14 <description>&lt;p&gt;Included in &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu /
15 Skolelinux&lt;/a&gt;, there are quite a lot of educational software.
16 Created to help teachers teach, and pupils learn. We have tried to
17 tag them all using debtags use::learning and role::program, and using
18 the debtags I was happy to be able to create a collage of the
19 educational software packages installed by default, sorted by the
20 debtag field. Here it is. Click on a image to learn more about the
21 program.&lt;/p&gt;

151 <description>&lt;p&gt;En ting
152 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux-prosjektet&lt;/a&gt; har
153 hatt mye glede av er studentprosjekter. F.eks. er
154 &lt;a href=&quot;http://linuxstopmotion.org/&quot;&gt;stillbildeanimasjonssystemet
155 Stopmotion&lt;/a&gt; resultat av et studentprosjekt i Skolelinux. De siste
156 månedene har en ivrig student veiledet av Marius Kotsbak i
157 &lt;a href=&quot;http://www.friprogramvareiskolen.no/&quot;&gt;FRiSK&lt;/a&gt; testet hva en
158 kan få til med en datamaskin til NOK 400,- (antagelig 1700,- med
159 skjerm, tastatur og mus) når det brukes i Skolelinux. Jeg spurte han
160 om et intervju.&lt;/p&gt;
161
162 &lt;p&gt;&lt;strong&gt;Hvem er du, og hva driver du med til daglig?&lt;/strong&gt;&lt;/p&gt;
163
164 &lt;p&gt;Jeg heter Nirosan Thiyagalingam. Jeg er 24 år og studerer
165 dataingeniør studiet ved Høgskolen i Sør Trøndelag. Interessen for
166 data har siden ung alder vært tilstede og jeg har i tillegg alltid
167 vært glad i å lære nye ting. Med teknologi som endres svært hurtig er
168 det alltid noe nytt å lære. Noe som igjen har gjort det svært
169 interessant å følge med på utviklingen. Jeg valgte dataingeniør
170 studiet grunnet ønske om å lære enda mer om programmering og utvikling
171 av store systemer.&lt;/p&gt;
172
173 &lt;p&gt;&lt;strong&gt;Hvordan kom du i kontakt med Skolelinux-prosjektet?&lt;/strong&gt;&lt;/p&gt;
174
175 &lt;p&gt;Skolelinux prosjektet hørte jeg først om i media. Men det var først
176 når jeg skulle velge bacheloroppgave at jeg fattet mer interesse for
177 prosjektet. Et enkelt søk på nettet førte meg til skolelinux sine
178 hjemmesider. Informasjonen jeg fant der gjorde meg enda nysgjerrig og
179 jeg valgte derfor en oppgave som gikk ut på å få en
180 &lt;a href=&quot;http://www.raspberrypi.org&quot;&gt;Raspberry PI&lt;/a&gt;. Altså en
181 ultra-billig datamaskin til å kjøre Debian Edu på lik linje med
182 vanlige datamaskiner. I løpet av prosjektet ble det gjort mye
183 forskning på nettet. Det var mye jeg måtte forstå rundt hvordan
184 operativsystemet Linux fungerte før jeg kunne angripe
185 problemet. Prøvde først å finne ut hvordan man kunne transformere en
186 vanlig installasjon av Skolelinux til Raspberry PI, men dette var
187 altfor vanskelig å jeg endte opp med mer spørsmål enn svar. Det ble
188 videre opprettet kontakt med Skolelinux utviklere på IRC der jeg fikk
189 diskutert hvilken retning jeg burde gå for å få til en fullverdig
190 løsning. Det ble bestemt at jeg skulle gå for å først installere
191 &lt;a href=&quot;http://www.raspbian.org/&quot;&gt;Raspian&lt;/a&gt;. Dette er et
192 operativsystem basert på Debian spesiallaget for Raspberry Pi sin
193 maskinvare. Nå som Debian var installert på datamaskinen gjenstod det
194 å installere de nødvendige Skolelinux pakkene for å få til et
195 fullverdig system. Disse pakkene ble installert manuelt i første
196 omgang, men ble senere installert automatisk via et script som Petter
197 Reinholdtsen laget. Dette scriptet er så enkel å bruke at man er i
198 gang med installasjonen i løpet av bare 5 minutter. Ikke nok med det,
199 alt skjer helt automatisk. Alt i alt er jeg veldig fornøyd med
200 resultatet av installasjonsprosessen. Raspberry Pi er en veldig svak
201 maskin og det merkes godt når man har installert Skolelinux på
202 den. Video og 3D-rendering fungerer utrolig dårlig, men nettsurfing og
203 kontorprogrammer fungerer godt. Det kan derfor konkluderes med at
204 datamaskinen er egnet for enkle oppgaver.
205
206 &lt;p&gt;Jeg syns det er viktig påpeke at dette kun er startfasen av en slik
207 løsning. På markedet finnes det nå maskiner som har bedre hardware enn
208 Raspberry Pi. Det er store muligheter for at man kan klare å
209 installere Skolelinux på disse også, og da forsvinner nok mest
210 sannsynlig ytelsesproblemene med Video og 3D rendering også.&lt;/p&gt;
211
212 &lt;p&gt;Det ble også prøvd med en løsning som gjorde at Raspberry Pi
213 fungerte som en tynnklient. Denne løsningen hadde langt bedre ytelse
214 med tanke på hastighet og brukeropplevelse. Men også her var video og
215 3D rendering dårlig. Det ble brukt en liten Linux distribusjon kalt
216 &lt;a href=&quot;http://www.berryterminal.com/&quot;&gt;BerryTerminal&lt;/a&gt; for å få til
217 dette.&lt;/p&gt;
218
219 &lt;p&gt;&lt;strong&gt;Hva er fordelene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
220
221 &lt;p&gt;Fordelen med Skolelinux er mange. At det er gratis er en stor
222 fordel, men at det er så mange som er med på å utvikle det og
223 vedlikeholde det er en enda større fordel. Allerede før jeg startet
224 med prosjektet så jeg mange fordeler, og når jeg nærmet meg sluttfasen
225 så jeg langt flere. At prosjektet skulle inneha en så høy kvalitet
226 hadde jeg aldri trodd. En vanlig Skolelinux installasjon har de
227 nødvendige programmene og funksjonen som både små og store skoler i
228 tillegg til organisasjoner kan klare seg med. At prosjektet tilbyr en
229 så komplett løsning er en kjempefordel. Installasjonen er knirkefri
230 og det er svært enkelt å installere og komme i gang.&lt;/p&gt;
231
232 &lt;p&gt;&lt;strong&gt;Hva er ulempene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
233
234 &lt;p&gt;Ulempene jeg ser med prosjektet er ryddigheten av websidene. Selv
235 om websidene er enkle og konsise er det allikevel ikke appellerende i
236 like stor grad som for eksempel
237 &lt;a href=&quot;http://www.ubuntu.com&quot;&gt;Ubuntu&lt;/a&gt; sine sider. Deres side
238 tilbyr, i tillegg til godt design og presentasjon, en nettbasert
239 emulator av deres operativsystem. Dette er en stor fordel slik jeg ser
240 det. Bortsett fra dette ser jeg absolutt ingen ulemper med
241 Skolelinux-prosjektet.&lt;/p&gt;
242
243 &lt;p&gt;&lt;strong&gt;Hvilken fri programvare bruker du til daglig?&lt;/strong&gt;&lt;/p&gt;
244
245 &lt;p&gt;Til daglig er jeg en flittig bruker av det åpne media
246 sentersystemet &lt;a href=&quot;http://xbmc.org/&quot;&gt;XBMC&lt;/a&gt;. Det enorme
247 samfunnet rundt dette prosjektet har gjort dette til et program som
248 dekker alles behov. Man kan tilpasse det akkurat slik man vil både med
249 tanke på utseende og funksjoner ved installere plug-ins eller
250 scripts.&lt;/p&gt;
251
252 &lt;p&gt;&lt;strong&gt;Hvilken strategi tror du er den rette å bruke for å få
253 skoler til å ta i bruk fri programvare?&lt;/strong&gt;&lt;/p&gt;
254
255 &lt;p&gt;Strategien som burde brukes sett fra mine øyne er
256 markedsføring. Jeg er sikker på at om flere skoler fikk et lite innsyn
257 i hvor bra Skolelinux er så ville de ikke nølt med å gå over fra noe
258 annet som koster de store summer. At skolelinux til de grader tilbyr
259 en så komplett løsning bure komme frem. Enten via reklamekampanjer
260 eller ved å sende ut folk til skoler for så å la skolenettverk
261 ansvarlige få teste ut hvordan Skolelinux fungerer i praksis. Om det
262 i tillegg ble utviklet gode websider og en emulator for å la brukere
263 prøve operativsystemet ville nok dette ha styrket inntrykket
264 betraktelig.&lt;/p&gt;

273 <description>&lt;p&gt;&lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu / Skolelinux&lt;/a&gt; is
274 an operating system based on Debian intended for use in schools. It
275 contain a turn-key solution for the computer network provided to
276 pupils in the primary schools. It provide both the central server,
277 network boot servers and desktop environments with heaps of
278 educational software. The project was founded almost 12 years ago,
279 2001-07-02. If you want to support the project, which is in need for
280 cash to fund developer gatherings and other project related activity,
281 &lt;a href=&quot;http://www.linuxiskolen.no/slxdebianlabs/donations.html&quot;&gt;please
282 donate some money&lt;/a&gt;.
283
284 &lt;p&gt;A topic that come up again and again on the Debian Edu mailing
285 lists and elsewhere, is the question on how to transform a Debian or
286 Ubuntu installation into a Debian Edu installation. It isn&#39;t very
287 hard, and last week I wrote a script to replicate the steps done by
288 the Debian Edu installer.&lt;/p&gt;
289
290 &lt;p&gt;The script,
291 &lt;a href=&quot;http://anonscm.debian.org/viewvc/debian-edu/branches/wheezy/debian-edu-config/share/debian-edu-config/tools/debian-edu-bless?view=markup&quot;&gt;debian-edu-bless&lt;a/&gt;
292 in the debian-edu-config package, will go through these six steps and
293 transform an existing Debian Wheezy or Ubuntu (untested) installation
294 into a Debian Edu Workstation:&lt;/p&gt;
295
296 &lt;ol&gt;
297
298 &lt;li&gt;Add skolelinux related APT sources.&lt;/li&gt;
299 &lt;li&gt;Create /etc/debian-edu/config with the wanted configuration.&lt;/li&gt;
300 &lt;li&gt;Install debian-edu-install to load preseeding values and pull in
301 our configuration.&lt;/li&gt;
302 &lt;li&gt;Preseed debconf database with profile setup in
303 /etc/debian-edu/config, and run tasksel to install packages
304 according to the profile specified in the config above,
305 overriding some of the Debian automation machinery.&lt;/li&gt;
306 &lt;li&gt;Run debian-edu-cfengine-D installation to configure everything
307 that could not be done using preseeding.&lt;/li&gt;
308 &lt;li&gt;Ask for a reboot to enable all the configuration changes.&lt;/li&gt;
309
310 &lt;/ol&gt;
311
312 &lt;p&gt;There are some steps in the Debian Edu installation that can not be
313 replicated like this. Disk partitioning and LVM setup, for example.
314 So this script just assume there is enough disk space to install all
315 the needed packages.&lt;/p&gt;
316
317 &lt;p&gt;The script was created to help a Debian Edu student working on
318 setting up &lt;a href=&quot;http://www.raspberrypi.org&quot;&gt;Raspberry Pi&lt;/a&gt; as a
319 Debian Edu client, and using it he can take the existing
320 &lt;a href=&quot;http://www.raspbian.org/FrontPage‎&quot;&gt;Raspbian&lt;/a&gt; installation and
321 transform it into a fully functioning Debian Edu Workstation (or
322 Roaming Workstation, or whatever :).&lt;/p&gt;
323
324 &lt;p&gt;The default setting in the script is to create a KDE Workstation.
325 If a LXDE based Roaming workstation is wanted instead, modify the
326 PROFILE and DESKTOP values at the top to look like this instead:&lt;/p&gt;
327
328 &lt;p&gt;&lt;pre&gt;
329 PROFILE=&quot;Roaming-Workstation&quot;
330 DESKTOP=&quot;lxde&quot;
331 &lt;/pre&gt;&lt;/p&gt;
332
333 &lt;p&gt;The script could even become useful to set up Debian Edu servers in
334 the cloud, by starting with a virtual Debian installation at some
335 virtual hosting service and setting up all the services on first
336 boot.&lt;/p&gt;

345 <description>&lt;p&gt;The &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu / Skolelinux
346 project&lt;/a&gt; is making great progress and made its second Wheezy based
347 release today. This is the release announcement:&lt;/p&gt;
348
349 &lt;p&gt;&lt;strong&gt;New features for Debian Edu 7.0.0 alpha1 released
350 2013-05-14&lt;/strong&gt;&lt;/p&gt;
351
352 &lt;p&gt;This is the release notes for for Debian Edu / Skolelinux 7.0.0 edu
353 alpha1, based on &lt;ahref=&quot;http://www.debian.org&quot;&gt;Debian&lt;/a&gt; with
354 codename &quot;Wheezy&quot;.&lt;/p&gt;
355
356 &lt;p&gt;&lt;strong&gt;About Debian Edu and Skolelinux&lt;/strong&gt;&lt;/p&gt;
357
358 &lt;p&gt;Debian Edu, also known as Skolelinux, is a Linux distribution based
359 on Debian providing an out-of-the box environment of a completely
360 configured school network. Immediatly after installation a school
361 server running all services needed for a school network is set up just
362 waiting for users and machines being added via GOsa², a comfortable
363 Web-UI. A netbooting environment is prepared using PXE, so after
364 initial installation of the main server from CD, DVD or USB stick all
365 other machines can be installed via the network.&lt;/p&gt;
366
367 &lt;p&gt;This is the first test release based on Wheezy (which currently is
368 not released yet). Basically this is an updated and slightly improved
369 version compared to the Squeeze release.&lt;/p&gt;
370
371 &lt;p&gt;&lt;strong&gt;Software updates&lt;/strong&gt;&lt;/p&gt;
372 &lt;ul&gt;
373 &lt;li&gt;Install freemind (0.9.0) by default, and stop installing vym by
374 default.&lt;/li&gt;
375 &lt;li&gt;Install chromium (26.0.1410.43) by default.&lt;/li&gt;
376 &lt;li&gt;Install goplay (0.5-1.1) to make golearn available by default.&lt;/li&gt;
377 &lt;li&gt;Updated support for Japanese input methods, now based on

379 &lt;/ul&gt;
380
381 &lt;p&gt;&lt;strong&gt;Other changes&lt;/strong&gt;&lt;/p&gt;
382 &lt;ul&gt;
383
384 &lt;li&gt;Switched default file system from ext3 to ext4 for speed and
385 reliability improvements.&lt;/li&gt;
386 &lt;li&gt;Got rid of unwanted winbind daemon and PAM setup activated because
387 of &lt;a href=&quot;http://bugs.debian.org/706434&quot;&gt;706434&lt;/a&gt;.&lt;/li&gt;
388 &lt;li&gt;Extended and improved the testsuite tests to detect more possible
389 problems.&lt;/li&gt;
390 &lt;li&gt;Corrected proxy handling to not set http_proxy to a bogus
391 direct:// URL.&lt;/li&gt;
392 &lt;li&gt;Corrected proxy setup for diskless workstations.&lt;/li&gt;
393 &lt;li&gt;Corrected PXE setup to use our updated udebs during installation.&lt;/li&gt;
394 &lt;li&gt;Made installation handling of low entropy level more robust.&lt;/li&gt;

397 &lt;li&gt;Fix bug in Roaming workstation PAM setup, making it impossible to
398 log in (&lt;a href=&quot;http://bugs.debian.org/706753&quot;&gt;706753&lt;/a&gt;).&lt;/li&gt;
399 &lt;/ul&gt;
400
401 &lt;p&gt;&lt;strong&gt;Known issues&lt;/strong&gt;&lt;/p&gt;
402 &lt;ul&gt;
403
404 &lt;li&gt;IP resolution for the local hostname give useless IPv6 address
405 (&lt;a href=&quot;http://bugs.debian.org/705900&quot;&gt;705900&lt;/a&gt;). Only install
406 libnss-myhostname on roaming workstations until it is fixed.&lt;/li&gt;
407 &lt;li&gt;DVD images are not yet ready.&lt;/li&gt;
408 &lt;li&gt;No mass import of user account data in GOsa (ldif or csv)
409 available yet (&lt;a href=&quot;http://bugs.debian.org/698840&quot;&gt;698840&lt;/a&gt;).&lt;/li&gt;
410 &lt;li&gt;Missing artwork for the KDE desktop (and probably a few others).&lt;/li&gt;
411 &lt;li&gt;KDE Debian submenu lacks icons.&lt;/li&gt;
412 &lt;li&gt;LXDE menu lacks entry for changing GOsa password
413 (website). Installing gosa-desktop will be an option.&lt;/li&gt;
414 &lt;li&gt;Backup configuration via web interface is impossible due to
415 password submission problem
416 (&lt;a href=&quot;http://bugs.debian.org/700257&quot;&gt;700257&lt;/a&gt;).&lt;/li&gt;

444 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Narvik_sparer_minst_9_millioner_p____bruke_Skolelinux.html</guid>
445 <pubDate>Fri, 10 May 2013 18:30:00 +0200</pubDate>
446 <description>&lt;p&gt;I fjor sommer ble jeg
447 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/Gladoppslag_om_Skolelinux_i_avisen_Fremover.html&quot;&gt;gledelig
448 overrasket&lt;/a&gt; over et oppslag i avisen Fremover om Narvik kommunes
449 bruk av &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt;. Oppslaget
450 var basert på et notat som besvarte spørsmål fra ordfører Tor Nysæter
451 og rådgiver for skolesektoren, Petter Falkbu, om bruken av Skolelinux
452 i Narvikskolene og konstnaden ved å gå over til Windows. For litt
453 over en uke siden siden fikk jeg endelig bedt kommunen om å få innsyn
454 i dette notatet, og det ble oversendt på epost tirsdag. Jeg fikk
455 &lt;a href=&quot;http://www.nuug.no/pub/offentliginnsyn/from-Narvik-kommune/2013-04-29-09:12-skolelinux-notat/PetterFalkbuogwindowsfornarvikskolen%20(L)351310.pdf&quot;&gt;lagt
456 ut notatet&lt;/a&gt; samme dag, og fikk i dag sjekket postlista til Narvik,
457 der jeg fant notatet som
458 &lt;a href=&quot;https://www.narvik.kommune.no/innsyn.aspx?response=arkivsak_detaljer&amp;arkivsakid=2013001023&amp;scripturi=/innsyn.aspx&amp;skin=infolink&amp;Mid1=301&amp;&quot;&gt;sak
459 2013/1023&lt;/a&gt;.&lt;/p&gt;
460
461 &lt;p&gt;Notatet forteller at Narvik ville måtte betalt minst 9 millioner
462 for å gå over til Windows på skolene. I tillegg dokumenterer notatet
463 at læreplanens krav oppfylles uten problemer ved bruk av Skolelinux.
464 Jeg anbefaler alle å lese de 10 sidene med gode argumenter for å kutte
465 unødige utgifter på IT i skoleverket. :)&lt;/p&gt;

473 <pubDate>Sun, 5 May 2013 07:40:00 +0200</pubDate>
474 <description>&lt;p&gt;When I woke up this morning, I was very happy to see that the
475 &lt;a href=&quot;http://www.debian.org/News/2013/20130504&quot;&gt;release announcement
476 for Debian Wheezy&lt;/a&gt; was waiting in my mail box. This is a great
477 Debian release, and I expect to move my machines at home over to it fairly
478 soon.&lt;/p&gt;
479
480 &lt;p&gt;The new debian release contain heaps of new stuff, and one program
481 in particular make me very happy to see included. The
482 &lt;a href=&quot;http://scratch.mit.edu/&quot;&gt;Scratch&lt;/a&gt; program, made famous by
483 the &lt;a href=&quot;http://www.code.org/&quot;&gt;Teach kids code&lt;/a&gt; movement, is
484 included for the first time. Alongside similar programs like
485 &lt;a href=&quot;http://edu.kde.org/kturtle/&quot;&gt;kturtle&lt;/a&gt; and
486 &lt;a href=&quot;http://wiki.sugarlabs.org/go/Activities/Turtle_Art&quot;&gt;turtleart&lt;/a&gt;,
487 it allow for visual programming where syntax errors can not happen,
488 and a friendly programming environment for learning to control the
489 computer. Scratch will also be included in the next release of Debian
490 Edu.&lt;/a&gt;
491
492 &lt;p&gt;And now that Wheezy is wrapped up, we can wrap up the next Debian
493 Edu/Skolelinux release too. The
494 &lt;a href=&quot;http://lists.debian.org/debian-edu/2013/04/msg00132.html&quot;&gt;first
495 alpha release&lt;/a&gt; went out last week, and the next should soon
496 follow.&lt;p&gt;

505 <description>&lt;p&gt;The Debian Edu / Skolelinux project is still going strong and made
506 its first Wheezy based release today. This is the release
507 announcement:&lt;/p&gt;
508
509 &lt;p&gt;&lt;strong&gt;New features for Debian Edu ~7.0.0 alpha0 released
510 2013-04-26&lt;/strong&gt;&lt;/p&gt;
511
512 &lt;p&gt;This is the release notes for for Debian Edu / Skolelinux ~7.0.0

514
515 &lt;p&gt;&lt;strong&gt;About Debian Edu and Skolelinux&lt;/strong&gt;&lt;/p&gt;
516
517 &lt;p&gt;&lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu, also known as
518 Skolelinux&lt;/a&gt;, is a Linux distribution based on Debian providing an
519 out-of-the box environment of a completely configured school
520 network. Immediatly after installation a school server running all
521 services needed for a school network is set up just waiting for users
522 and machines being added via GOsa², a comfortable Web-UI. A netbooting
523 environment is prepared using PXE, so after initial installation of
524 the main server from CD, DVD or USB stick all other machines can be
525 installed via the network.&lt;/p&gt;
526
527 &lt;p&gt;This is the first test release based on Wheezy (which currently is
528 not released yet). Basically this is an updated and slightly improved
529 version compared to the Squeeze release.&lt;/p&gt;
530
531 &lt;p&gt;&lt;strong&gt;Software updates&lt;/strong&gt;&lt;/p&gt;
532
533 &lt;ul&gt;
534 &lt;li&gt;Everything which is new in Debian Wheezy, eg:
535 &lt;ul&gt;
536 &lt;li&gt;Linux kernel 3.2.x&lt;/li&gt;
537 &lt;li&gt;Desktop environments KDE &quot;Plasma&quot; 4.8.4, GNOME 3.4, and LXDE 4
538 (KDE is installed by default; to choose GNOME or LXDE: see
539 manual.)&lt;/li&gt;
540 &lt;li&gt;Web browser Iceweasel 10 ESR&lt;/li&gt;
541 &lt;li&gt;LibreOffice 3.5.4&lt;/li&gt;
542 &lt;li&gt;LTSP 5.4.2&lt;/li&gt;
543 &lt;li&gt;GOsa 2.7.4&lt;/li&gt;
544 &lt;li&gt;CUPS print system 1.5.3&lt;/li&gt;
545 &lt;li&gt;Educational toolbox GCompris 12.01&lt;/li&gt;
546 &lt;li&gt;Music creator Rosegarden 12.04&lt;/li&gt;
547 &lt;li&gt;Image editor Gimp 2.8.2&lt;/li&gt;
548 &lt;li&gt;Virtual universe Celestia 1.6.1&lt;/li&gt;
549 &lt;li&gt;Virtual stargazer Stellarium 0.11.3&lt;/li&gt;
550 &lt;li&gt;Scratch visual programming environment 1.4.0.6&lt;/li&gt;
551 &lt;li&gt;New version of debian-installer from Debian Wheezy, see
552 &lt;a href=&quot;http://www.debian.org/releases/wheezy/installmanual&quot;&gt;installation
553 manual&lt;/a&gt; for more details.&lt;/li&gt;
554 &lt;li&gt;Debian Wheezy includes about 37000 packages available for
555 installation.&lt;/li&gt;
556 &lt;li&gt;More information about Debian Wheezy 7.0 is provided in the
557 &lt;a href=&quot;http://www.debian.org/releases/wheezy/releasenotes&quot;&gt;release notes&lt;/a&gt; and the &lt;a href=&quot;http://www.debian.org/releases/wheezy/installmanual&quot;&gt;installation manual&lt;/a&gt;.&lt;/li&gt;
558 &lt;/ul&gt;&lt;/li&gt;
559 &lt;/ul&gt;
560
561 &lt;p&gt;&lt;strong&gt;Documentation&lt;/strong&gt;&lt;/p&gt;
562 &lt;ul&gt;
563 &lt;li&gt;The (&lt;a href=&quot;http://wiki.debian.org/DebianEdu/Documentation/Wheezy&quot;&gt;English&lt;/a&gt;) Debian Edu Wheezy Manual is fully translated to
564 German, French, Italian and Danish. Partly translated versions exist
565 for Norwegian Bokmal and Spanish.&lt;/li&gt;
566 &lt;/ul&gt;
567
568 &lt;p&gt;&lt;Strong&gt;LDAP related changes&lt;/strong&gt;&lt;/p&gt;
569 &lt;ul&gt;
570 &lt;li&gt;Slight changes to some objects and acls to have more types to
571 choose from when adding systems in GOsa. Now systems can be of type
572 server, workstation, printer, terminal or netdevice.&lt;/li&gt;
573 &lt;/ul&gt;
574
575 &lt;p&gt;&lt;strong&gt;Other changes&lt;/strong&gt;&lt;/p&gt;
576 &lt;ul&gt;
577 &lt;li&gt;LTSP clients start as diskless workstation / thin client can be
578 configured via command line argument -- or individually adding an
579 entry in lts.conf or LDAP.&lt;li&gt;
580 &lt;li&gt;GOsa gui: Now some options that seemed to be available, but are non
581 functional, are greyed out (or are not clickable). Some tabs are
582 completely hidden to the end user, others even to the GOsa admin.&lt;/li&gt;
583 &lt;/ul&gt;
584
585 &lt;p&gt;&lt;strong&gt;Regressions&lt;/strong&gt;&lt;/p&gt;
586 &lt;ul&gt;
587 &lt;li&gt;No mass import of user account data in GOsa (ldif or csv) available
588 yet.&lt;/li&gt;
589 &lt;/ul&gt;
590
591 &lt;p&gt;&lt;strong&gt;No updated artwork&lt;/strong&gt;&lt;/p&gt;
592
593 &lt;ul&gt;
594 &lt;li&gt;Updated artwork which is visible during installation, in the login
595 screen and as desktop wallpaper is still missing or the same as we
596 had for our Squeeze based release.&lt;/li&gt;
597 &lt;/ul&gt;

623 <description>&lt;p&gt;This years first &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux /
624 Debian Edu&lt;/a&gt; developer gathering take place the coming weekend in Trondheim.
625 Details about the gathering can be found
626 &lt;a href=&quot;http://www.friprogramvareiskolen.no/Gathering/2013-04-19-21-Trondheim&quot;&gt;on
627 the FRiSK wiki&lt;/a&gt;. The dates are 19-21th of April 2013, and online
628 participation for those unable to make it in person is very welcome,
629 and I plan to participate online myself as I could not leave Oslo this
630 weekend.&lt;/p&gt;
631
632 &lt;p&gt;The focus of the gathering is to work on the web pages and project
633 infrastructure, and to continue the work on the Wheezy based Debian
634 Edu release.&lt;/p&gt;
635
636 &lt;p&gt;See you on &lt;a href=&quot;irc://irc.debian.org/%23debian-edu&quot;&gt;IRC, #debian-edu on irc.debian.org,&lt;/a&gt; then?&lt;/p&gt;

643 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Skolelinux_6_got_a_video_review_from_Pcwizz.html</guid>
644 <pubDate>Sun, 17 Mar 2013 10:30:00 +0100</pubDate>
645 <description>&lt;p&gt;Via
646 &lt;a href=&quot;https://twitter.com/pcwizz/status/313044373262716930&quot;&gt;twitter&lt;/a&gt;
647 I just discovered that &lt;a href=&quot;http://pcwizz.net/&quot;&gt;Pcwizz&lt;/a&gt; have
648 done a &lt;a href=&quot;http://www.youtube.com/watch?v=wPzTZ61Pcuc&quot;&gt;video
649 review&lt;/a&gt; on Youtube of &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux
650 / Debian Edu&lt;/a&gt; version 6. He installed the standalone profile and
651 the video show a walk-through of of the menu content, demonstration of
652 a few programs and his view of our distribution.&lt;/p&gt;
653
654 &lt;p&gt;There is also some really nice quotes (transcribed by me, might
655 have heard wrong). While looking thought the Graphics menu:&lt;/p&gt;
656
657 &lt;blockquote&gt;
658 &quot;Basically everything you ever need in a school environment.&quot;
659 &lt;/blockquote&gt;
660
661 &lt;p&gt;And as a general evaluation of the entire distribution:&lt;/p&gt;
662
663 &lt;blockquote&gt;
664 &quot;So, yeah, a bit bloated. It kept all the Debian stuff in there, just
665 to keep it nice and GNU. So, I do not want to go on about it, but
666 lets give it 7 out of 10. I am not going to use it. That is because
667 I am not deploying a school network. There may be some mythical
668 feature to help you deploy Skolelinux on a school network.&quot;
669 &lt;/blockquote&gt;
670
671 &lt;p&gt;To bad he did not test the server profile, and discovered the PXE
672 installation option. It make it possible to install only the main
673 server from CD, and the rest of the machines via the net, and might be
674 considered the mythical feature he talk about. :)&lt;/p&gt;
675
676 &lt;p&gt;While looking through the menus, there is also this funny comment
677 about the part of the K menu generated from the Debian menu subsystem:
678
679 &lt;blockquote&gt;
680 &quot;[The K menu] have a special Debian section for software that no-one
681 is going to look at, because it contain lots of junky stuff that you
682 actually don&#39;t need in the education distribution, but have just been
683 included because it isn&#39;t stripped out for some reason.&quot;
684 &lt;/blockquote&gt;
685
686 &lt;p&gt;I guess it is yet another argument for merging the Debian menu and
687 Gnome/KDE desktop menu entries into
688 &lt;a href=&quot;http://wiki.debian.org/Proposals/DebianMenuUsingDesktopEntries&quot;&gt;one
689 consistent menu system&lt;/a&gt; instead of two incomplete and partly
690 inconsistent menu systems.&lt;/p&gt;
691
692 &lt;p&gt;The entire video is available below for those accepting iframe
693 embedding:&lt;/p&gt;

797 <title>Skolelinux-intervju: Helge Tore Høyland</title>
798 <link>http://people.skolelinux.org/pere/blog/Skolelinux_intervju__Helge_Tore_H_yland.html</link>
799 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Skolelinux_intervju__Helge_Tore_H_yland.html</guid>
800 <pubDate>Fri, 22 Feb 2013 08:10:00 +0100</pubDate>
801 <description>&lt;p&gt;Etter en lang pause og travle uker har jeg endelig klart å få
802 samlet et nytt intervju med en av folkene i
803 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt;-miljøet.
804 Denne gang er det Helge Tore Høyland, en mangeårig bidragsyter på
805 epostlistene og ellers i prosjektet.&lt;/p&gt;
806
807 &lt;p&gt;&lt;strong&gt;Hvem er du, og hva driver du med til daglig?&lt;/strong&gt;&lt;/p&gt;
808
809 &lt;p&gt;Eg er IT-konsulent/teknikker hjå eit firma i Steinkjer med navn
810 &lt;a href=&quot;http://unoit.no/&quot;&gt;Uno IT&lt;/a&gt;. Uno IT er eit lite firma som
811 drifter nettverk og maskiner for små og mellomstore firma
812 Steinkjer-området. Per dags dato er me 2 ansatte. Min faglege bakgrunn
813 er Fagbrev som it-teknikker, samt nokre fag innen nettverk- og
814 server-drift frå HiST og NTNU. Dagleg arbeid består i oppsett av nye
815 maskiner og hjelp til sluttbrukere, samt oppsett og vedlikehold av eit
816 vidt spekter av fagsystemer ute hjå kunder. Erfaring med Skolelinux
817 har eg hatt i forbindelse med drifting av
818 &lt;a href=&quot;http://www.bjorkly.no/&quot;&gt;Bjørkly skule&lt;/a&gt;, ein privat
819 grunnskule i Namsos-området. I dag har skulen 65 elever, 15 lærere, 1
820 hovedserver og ca 60 klienter som kjører halvtjukt. Eg har bygd og
821 driftet systemet sidan summaren 2006.&lt;/p&gt;
822
823 &lt;p&gt;&lt;strong&gt;Hvordan kom du i kontakt med Skolelinux-prosjektet?&lt;/strong&gt;&lt;/p&gt;
824
825 &lt;p&gt;Eg kom i kontakt med Skolelinux-prosjektet via ein artikkel i eit
826 fagblad, som eg ikkje lenger hugsar namnet på. I og med at eg allereie
827 hadde pusla med nettverk for ein annan skule, fatta eg straks
828 interesse for prosjektet.&lt;/p&gt;
829
830 &lt;p&gt;&lt;strong&gt;Hva er fordelene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
831
832 &lt;p&gt;Fordelane med Skolelinux er sentralisert administrasjon og svært
833 mange gode verktøy «ut av boksen». Veldig kjekt å kunne drifte 60
834 klientar med berre å «bry» seg med ein server. Levetid for systemets
835 hardware er og ein veldig fin effekt. I tillegg kjem fordelar som økt
836 sikkerhet og mindre lisenskostnader. Etter min erfaring er det og
837 mykje mindre driftskostnader med eit slikt system enn konkurrerande
838 system, pga enkelhet med sentralisert administrasjon. På grunn av at
839 Skolelinux er basert på Debian er det òg svært stabilt.&lt;/p&gt;
840
841 &lt;p&gt;&lt;strong&gt;Hva er ulempene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
842
843 &lt;p&gt;Ulemper er mangel på vilje til å følge standarer ute i markedet,
844 som fører til mangel på støtte til nokre mykje brukte ting. Flash og
845 Java er typiske eksempel. Sidan Debian satsar på stabilitet framfor å
846 ha nyeste pakke av eit program, kan ein i nokre tilfeller kome borti
847 at program vert «for gamle». Det er spesielt nettlesaren som er
848 utsett. Mangel på vilje til å utvikle pedagogisk programvare, i Noreg,
849 for «alle» platformer fører òg til noko hovudbry.&lt;/p&gt;
850
851 &lt;p&gt;&lt;strong&gt;Hvilken fri programvare bruker du til daglig?&lt;/strong&gt;&lt;/p&gt;
852
853 &lt;p&gt;Til dagleg bruker eg svært mange forskjellige «fri programvare»
854 program. Firefox, Thunderbird, Freecommander, ImgBurn, Clonezilla,
855 OCS inventory, Icinga, Skolelinux, SystemRescueCD og mykje meir.&lt;/p&gt;
856
857 &lt;p&gt;&lt;strong&gt;Hvilken strategi tror du er den rette å bruke for å få
858 skoler til å ta i bruk fri programvare?&lt;/strong&gt;&lt;/p&gt;
859
860 &lt;p&gt;Strategisk må ein fokusere på at sluttbruker eigentleg ikkje er så
861 fokusert på at det er fri programvare men at det skal «berre fungere».
862 Gjer det enkelt å bruker og ikkje minst å administrere. For Skolelinux
863 sin del må ein få eit betre fokus på overganger. Utbytting av servere
864 må gå meir automatisk, import og eksport av brukerbase og maskinbase
865 med meir må kunne gå enkelt og oppgradering til neste versjon må bli
866 mykje meir automatisk og gjennomtesta. Ein må unngå at ein må sette
867 opp frå start når ein byter ut ein server eller oppgraderer til neste
868 versjon. For å få Skolelinux til å bli eit betre alternativ for skular
869 må ein ha fokus på nettlesaren. Denne må bli «up to date» og støtte
870 dei protokollar og tillegg som vert brukt av forlag med meir. Etter
871 kvart som meir og meir blir flytta ut i «skya» vert dette viktigare og
872 viktigare. Ein kunne ynskje og jobbe for at forlag med fleire tar i
873 bruk opne standarer, men inntil det skjer, må systemet kunne brukast
874 mot desse fagsystema.&lt;/p&gt;
875
876 &lt;p&gt;For meg har prosjektet med Skolelinux vore ein svært artig og
877 lærerik prosess. Miljøet rundt er ikkje enormt stort, dog stort nok,
878 men det er svært hjelpevillig og engasjert.&lt;/p&gt;

883 <title>A Christmas present for Skolelinux / Debian Edu</title>
884 <link>http://people.skolelinux.org/pere/blog/A_Christmas_present_for_Skolelinux___Debian_Edu.html</link>
885 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/A_Christmas_present_for_Skolelinux___Debian_Edu.html</guid>
886 <pubDate>Fri, 28 Dec 2012 09:20:00 +0100</pubDate>
887 <description>&lt;p&gt;I was happy to discover a few days ago that the
888 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux / Debian Edu&lt;/a&gt;
889 project also this year received a Christmas present from Another
890 Agency in Trondheim. NOK 1000,- showed up on our donation account
891 December 24th. I want to express our thanks for this very welcome
892 present. As the Debian Edu / Skolelinux project is very short on
893 funding these days, and thus lack the money to do regular developer
894 gatherings, this donation was most welcome. One developer gathering
895 cost around NOK 15&amp;nbsp;000,-, so we need quite a lot more to keep the
896 development pace we want. Thus, I hope their example this year is
897 followed by many others. :)&lt;/p&gt;
898
899 &lt;p&gt;The public list of donors can be found on
900 &lt;a href=&quot;http://www.linuxiskolen.no/slxdebianlabs/donations.html&quot;&gt;the
901 donation page&lt;/a&gt; for the project, which also contain instructions if
902 you want to donate to the project.&lt;/p&gt;

907 <title>Ledger - double-entry accounting using text based storage format</title>
908 <link>http://people.skolelinux.org/pere/blog/Ledger___double_entry_accounting_using_text_based_storage_format.html</link>
909 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Ledger___double_entry_accounting_using_text_based_storage_format.html</guid>
910 <pubDate>Tue, 18 Dec 2012 23:30:00 +0100</pubDate>
911 <description>&lt;p&gt;A few days ago I came across
912 &lt;a href=&quot;http://joeyh.name/blog/entry/hledger/&quot;&gt;a blog post from Joey
913 Hess&lt;/a&gt; describing &lt;a href=&quot;http://ledger-cli.org/&quot;&gt;ledger&lt;/a&gt; and
914 hledger, a text based system for double-entry accounting. I found it
915 interesting, as I am involved with several organizations where
916 accounting is an issue, and I have not really become too friendly with
917 the different web based systems we use. I find it hard to find what I
918 look for in the menus and even harder try to get sensible data out of
919 the systems. Ledger seem different. The accounting data is kept in
920 text files that can be stored in a version control system, and there
921
922 are at least &lt;a href=&quot;https://github.com/ledger/ledger/wiki/Ports&quot;&gt;five
923 different implementations&lt;/a&gt; able to read the format. An example
924 entry look like this, and is simple enough that it will be trivial to
925 generate entries based on CVS files fetched from the bank:&lt;/p&gt;
926
927 &lt;blockquote&gt;&lt;pre&gt;
928 2004-05-27 Book Store
929 Expenses:Books $20.00
930 Liabilities:Visa
931 &lt;/pre&gt;&lt;/blockquote&gt;
932
933 &lt;p&gt;The concept seemed interesting enough for me to check it out and
934 look for others using it. I found blog posts from
935 &lt;a href=&quot;http://blog.spang.cc/posts/hledger_rocks_my_world/&quot;&gt;Christine
936 Spang&lt;/a&gt;,
937 &lt;a href=&quot;http://bugsplat.info/2010-05-23-keeping-finances-with-ledger.html&quot;&gt;Pete
938 Keen&lt;/a&gt;,
939 &lt;a href=&quot;http://blog.andrewcantino.com/blog/2010/11/06/command-line-accounting-with-ledger-and-reckon/&quot;&gt;Andrew
940 Cantino&lt;/a&gt; and
941 &lt;a href=&quot;http://blog.iphoting.com/blog/2012/11/29/command-line-double-entry-accounting/&quot;&gt;Ronald
942 Ip&lt;/a&gt; describing how they use it, as well as a post from
943 &lt;a href=&quot;https://groups.google.com/forum/?fromgroups=#!topic/ledger-cli/r0oWjwbQ9Bo&quot;&gt;Bradley
944 M. Kuhn&lt;/a&gt; at the Software Freedom Conservancy. All seemed like good
945 recommendations fitting my need.&lt;/p&gt;
946
947 &lt;p&gt;The &lt;a href=&quot;http://packages.qa.debian.org/l/ledger.html&quot;&gt;ledger&lt;/a&gt;
948 package is available in Debian Squeeze, while the
949 &lt;a href=&quot;http://packages.qa.debian.org/h/haskell-hledger.html&quot;&gt;hledger&lt;/a&gt;
950 package only is available in Debian Sid. As I use Squeeze, ledger
951 seemed the best choice to get started.&lt;/p&gt;
952
953 &lt;p&gt;To get some real data to test on, I wrote a
954 &lt;a href=&quot;http://www.nuug.no/tools/lodo2ledger&quot;&gt;web scraper&lt;/a&gt; for
955 &lt;a href=&quot;http://www.lodo.no/&quot;&gt;LODO&lt;/a&gt;, the accounting system used by
956 the &lt;a href=&quot;http://www.nuug.no/&quot;&gt;NUUG&lt;/a&gt; association, and started to
957 play with the data set. I&#39;m not really deeply into accounting, but I
958 am able to get a simple balance and accounting status for example
959 using the &quot;&lt;tt&gt;ledger balance&lt;/tt&gt;&quot; command. But I will have to
960 gather more experience before I know if the ledger way is a good fit
961 for the organisations I am involved in.&lt;/p&gt;

966 <title>Debian Edu interview: Angela Fuß</title>

968 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Angela_Fu_.html</guid>
969 <pubDate>Wed, 14 Nov 2012 21:30:00 +0100</pubDate>
970 <description>&lt;p&gt;Here is another interview with one of the people in the &lt;a
971 href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu and Skolelinux&lt;/a&gt;
972 community. I am running short on people willing to be interviewed, so
973 if you know about someone I should interview, Please send me an email.
974 After asking for many months, I finally managed to lure another one of
975 the people behind the German
976 &quot;&lt;a href=&quot;http://wiki.it-zukunft-schule.de/&quot;&gt;IT-Zukunft Schule&lt;/a&gt;&quot;
977 project out from maternity leave to conduct an interview. Give a warm
978 welcome to Angela Fuß. :)&lt;/p&gt;
979
980 &lt;p&gt;&lt;strong&gt;Who are you, and how do you spend your days?&lt;/strong&gt;&lt;/p&gt;
981
982 &lt;p&gt;I am a 39-year-old woman living in the very north of Germany near
983 Denmark. I live in a patchwork family with &quot;my man&quot; Mike Gabriel, my
984 two daughters, Mikes daughter and Mikes and my rather newborn son.
985
986 &lt;p&gt;At the moment - because of our little baby - I am spending most of
987 the day by being a caring and organising mom for all the kids.
988 Besides that I am really involved into and occupied with several inner
989 growth processes: New born souls always bring the whole familiar
990 system into movement and that needs time and focus ;-). We are also
991 in the middle of buying a house and moving to it.&lt;/p&gt;
992
993 &lt;p&gt;In 2013 I will work again in my job in a German foundation for
994 nature conservation. I am doing public relation work there. Besides
995 that - and that is the connection to Skolelinux / Debian Edu - I am
996 working in our own school project &quot;IT-Zukunft Schule&quot; in North
997 Germany. I am responsible for the quality assurance, the customer
998 relationship management and the communication processes in the
999 project.&lt;/p&gt;
1000
1001 &lt;p&gt;Since 2001 I constantly have been training myself in communication
1002 and leadership. Besides that I am a forester, a landscaping gardener
1003 and a yoga teacher.&lt;/p&gt;
1004
1005 &lt;p&gt;&lt;strong&gt;How did you get in contact with the Skolelinux / Debian Edu
1006 project?&lt;/strong&gt;&lt;/p&gt;
1007
1008 &lt;p&gt;I fell in love with Mike ;-).&lt;/p&gt;
1009
1010 &lt;p&gt;Very soon after getting to know him I was completely enrolled into
1011 Free Software. At this time Mike did IT-services for one newly
1012 founded school in Kiel. Other schools in Kiel needed concepts for
1013 their IT environment. Often when Mike came home from working at the
1014 newly founded school I found myself listening to his complaints about
1015 several points where the communication with the schools head or the
1016 teachers did not work. So we were clear that he would not work for
1017 one more school if we did not set up a structure for communication
1018 between him, the schools head, the teachers, the students and the
1019 parents.&lt;/p&gt;
1020
1021 &lt;p&gt;Together with our friend and hardware supplier Andreas Buchholz we
1022 started to get an overview of free software solutions suitable for
1023 schools. One day before Christmas 2010 Mike and I had a date with Kurt
1024 Gramlich in Gütersloh. As Kurt and I are really interested in building
1025 networks of people and in being in communication we dived into
1026 Skolelinux and brought it to the first grammar schools in Northern
1027 Germany.&lt;/p&gt;
1028
1029 &lt;p&gt;For information about our school project you can read
1030 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Mike_Gabriel.html&quot;&gt;the
1031 interview with Mike Gabriel&lt;/a&gt;.&lt;/p&gt;
1032
1033 &lt;p&gt;&lt;strong&gt;What do you see as the advantages of Skolelinux / Debian
1034 Edu?&lt;/strong&gt;&lt;/p&gt;
1035
1036 &lt;p&gt;First I have to say: I cannot answer this question technically. My
1037 answer comes rather from a social point of view.&lt;/p&gt;
1038
1039 &lt;p&gt;The biggest advantage of Skolelinux / Debian Edu I see is the large
1040 and strong international community of Debian Developers in the
1041 background which is very alive and connected over mailinglists, blogs
1042 and meetings. My constant feeling for the Debian Community is: If
1043 something does not work they will somehow fix it. All is well
1044 ;-). This is of course a user experience. What I also get as a big
1045 advantage of Skolelinux / Debian Edu is that everybody who uses it and
1046 works with it can also contribute to it - that includes students,
1047 teachers, parents...&lt;/p&gt;
1048
1049 &lt;p&gt;&lt;strong&gt;What do you see as the disadvantages of Skolelinux / Debian
1050 Edu?&lt;/strong&gt;&lt;/p&gt;
1051
1052 &lt;p&gt;I will answer this question relating to the internal structure of
1053 Skolelinux / Debian Edu.&lt;/p&gt;
1054
1055 &lt;p&gt;What I see as a major disadvantage is that there is a gap between
1056 the group of developers for Debian Edu and the people who make the
1057 marketing, that means the people that bring Skolelinux to the
1058 schools. There is a lack of communication between these two groups and
1059 I think that does not really work for Skolelinux / Debian Edu.&lt;/p&gt;
1060
1061 &lt;p&gt;Further I appreciate that Skolelinux / Debian Edu is known as a
1062 do-ocracy. Nevertheless I keep asking myself if at some points a
1063 democracy or some kind of hierarchical project structure would be good
1064 and helpful. I am also missing some kind of contact between the
1065 Skolelinux / Debian Edu communities in Europe or on an international
1066 level. I think it would be good if there was more sharing between the
1067 different countries using Skolelinux / Debian Edu.&lt;/p&gt;
1068
1069 &lt;p&gt;&lt;strong&gt;Which free software do you use daily?&lt;/strong&gt;&lt;/p&gt;
1070
1071 &lt;p&gt;On my laptop I am still using an Ubuntu 10.04 with a Gnome Desktop
1072 on. As applications I use Openoffice.org, Gedit, Firefox, Pidgin,
1073 LaTeX and GnuCash. For mails I am using Horde. And I am really fond of
1074 my N900 running with Maemo.&lt;/p&gt;
1075
1076 &lt;p&gt;&lt;strong&gt;Which strategy do you believe is the right one to use to
1077 get schools to use free software?&lt;/strong&gt;&lt;/p&gt;
1078
1079 &lt;p&gt;I am really convinced that in our school project &quot;IT-Zukunft
1080 Schule&quot; we have developed (and keep developing) a great way to get
1081 schools to use Free Software. We have written a detailed concept for
1082 that so I cannot explain the whole thing here. But in a nutshell the
1083 strategy has three crucial pillars:&lt;/p&gt;
1084
1085 &lt;ul&gt;
1086
1087 &lt;li&gt;We really take time to get what sort of stories, questions and
1088 concerns the schools head and the teachers have about using different
1089 kinds of IT and we take time to enrol them into Free Software.&lt;/li&gt;
1090
1091 &lt;li&gt;Our solution for schools is never just technical. In the centre
1092 are always the people who are going to use the software. From the very
1093 beginning of the planning for a school, we tell the schools head that
1094 they are paying us not only for a technical solution for their school,
1095 they also pay us for leading all the communication processes
1096 needed. If they do not want that, we are not working with them because
1097 we cannot give a guarantee for the quality of our work then.&lt;/li&gt;
1098
1099 &lt;li&gt;Another focus lies in the training of teachers and students in
1100 co-administrating the IT-System at their school. They start getting in
1101 contact with the Skolelinux / Debian Edu community and they get the
1102 offer to become more and more independent from us.&lt;/li&gt;
1103
1104 &lt;/ul&gt;

1112 <pubDate>Sun, 14 Oct 2012 20:00:00 +0200</pubDate>
1113 <description>&lt;p&gt;Tirsdag 2012-10-09 sendte jeg følgende leserinnlegg til avisen
1114 &lt;a href=&quot;http://www.fremover.no/&quot;&gt;Fremover&lt;/a&gt;, etter å ha vært nordpå
1115 noen dager og lest noen gamle aviser. Publiserer den her i sin helhet
1116 for fremtidig referanse. Fremover publiserer dessverre ikke
1117 leserinnlegg på nett.&lt;/p&gt;
1118
1119 &lt;blockquote&gt;
1120 &lt;p&gt;To: redaksjon (at) fremover.no
1121 &lt;br&gt;Subject: Leserinnlegg til Fremover: Skolelinux noe for Ballangen?&lt;/p&gt;
1122
1123 &lt;p&gt;Ærede redaktør&lt;/p&gt;
1124
1125 &lt;p&gt;I sommer (2012-07-23) hadde Fremover et oppslag om at Narvik
1126 kommune hadde spart mellom 10 og 20 millioner kroner de siste årene på
1127 å bruke Skolelinux på sine skoler. Harstad har også tatt i bruk
1128 Skolelinux på alle sine skoler. Som tidligere Ballangsværing gledet
1129 det meg stort å se at skoleløsningen vi har utviklet siden 2001 tas i
1130 bruk i området der jeg vokste opp, og dermed bidrar til en bedre og
1131 billigere skolehverdag.&lt;/p&gt;
1132
1133 &lt;p&gt;Skolelinux er en komplett IT-løsning for elevnettverket på en
1134 skole, med både nettverkstjenester og løsning for elevmaskiner med
1135 pedagogisk programvare, som tillater en å øke levetiden på en
1136 datamaskin i skolen med mange år. En undersøkelse publisert i mars
1137 2012 viste at de 56 norske skolene som har offentliggjort at de bruker
1138 Skolelinux eller annen Linuxutgave hadde 36% større PC-tetthet enn
1139 landsgjennomsnittet, når en ser på tall rapportert til Grunnskolens
1140 Informasjonssystem. I følge Paul Reidar Løsnesløkken, IKT-konsulent i
1141 Nord-Odal, fungerer datamaskiner godt til de er 8 til 10 år gamle.&lt;/p&gt;
1142
1143 &lt;p&gt;I høst (2012-09-29) fortalte Fremover hvordan Ballangen kommune har
1144 opparbeidet seg 20 millioner i underskudd og nok havner på Robek-lista
1145 fra nyttår. Kanskje Ballangen også burde ta i bruk Skolelinux for å
1146 spare penger? Hvis kommunen mangler kompetanse lokalt på Linux finnes
1147 det kommersielle selskaper som tilbyr driftstjenester rundt
1148 Skolelinux, og jeg bør vel avsløre at jeg selv er involvert i et av
1149 dem, Skolelinux Drift AS. Kommunen kan dermed få hjelp hvis de ikke
1150 ønsker å bygge opp egen kompetanse.&lt;/p&gt;
1151

1176 <pubDate>Sat, 13 Oct 2012 12:10:00 +0200</pubDate>
1177 <description>&lt;p&gt;&lt;a href=&quot;http://no.speling.org/&quot;&gt;Den frie norske stavekontrollen&lt;/a&gt;
1178 består av ca. 1,3 millioner bokmåls- og nynorskord. Det er mange
1179 kilder til ordene, f.eks. den norske ordbanken, norske nett-aviser,
1180 stavekontrollbrukere og korrekturlesere, og endel feil har sneket seg
1181 inn i databasen over ord. For å finne og fikse feilene trengs det
1182 korrekturlesing. Her kommer frivillige inn.&lt;/p&gt;
1183
1184 &lt;p&gt;Hvis du vil bidra med korrektur av orddatabasen, kan du melde deg
1185 frivillig som bokmåls- eller nynorskkorrekturleser og få tilsendt en
1186 liten bunke ord på epost hver dag, lese over og sende inn på epost
1187 tilbake til korrekturlesing-systemet. Jo flere som sjekker, jo
1188 raskere kommer vi igjennom hele databasen. Så langt har vi oppdaget
1189 341 bokmålsord og 50 nynorskord som ikke skal vært med i databasen.
1190 Det er nok noen flere. I tillegg har korrekturleserne oppdaget flere
1191 ord som manglet, og fått lagt dem inn i stavekontrollen.&lt;/p&gt;
1192
1193 &lt;p&gt;Hvis du vil bidra, følg instruksene på
1194 &lt;a href=&quot;http://no.speling.org/dokumentasjon.html&quot;&gt;prosjektsidene&lt;/a&gt;
1195
1196 for nye bidragsytere, og ta kontakt med Håvard eller epostlisten
1197 &lt;a href=&quot;https://lister.ping.uio.no/mailman/listinfo/i18n-no&quot;&gt;i18n-no&lt;/a&gt;.
1198 Gode norskkunnskaper er en fordel, og vilje til å sjekke
1199 &lt;a href=&quot;http://www.nob-ordbok.uio.no/perl/ordbok.cgi&quot;&gt;ordboka&lt;/a&gt; et
1200 krav!&lt;/p&gt;

1208 <pubDate>Tue, 2 Oct 2012 09:20:00 +0200</pubDate>
1209 <description>&lt;p&gt;I helga fikk jeg endelig pakket sammen en ny versjon av den norske
1210 stavekontrollen, og gikk ut versjon 2.1 etter at det var gått fire og
1211 et halvt år siden sist. I dag fikk vi sendt ut annonseringen. Her er
1212 det vi sendte ut:&lt;/p&gt;
1213
1214 &lt;p&gt;Oslo, 2012-10-02&lt;/p&gt;
1215
1216 &lt;p&gt;&lt;strong&gt;Pressemelding: Ny utgave av norsk stavekontroll med
1217 synonymordliste&lt;/strong&gt;&lt;/p&gt;
1218
1219 &lt;p&gt;Mer enn fire år etter at forrige utgave av den frie norske
1220 stavekontrollen ble utgitt, er en ny og forbedret versjon klar. Dette er
1221 noe utviklerne er veldig glade for.&lt;/p&gt;
1222
1223 &lt;p&gt;Den største endringen er at byggesystemet for stavekontrollen er
1224 skrevet om til å akseptere ord med bindestrek (f.eks. «e-post»). Litt
1225 over 10.000 slike ordformer er lagt til i orddatabasen. I tillegg er
1226 det kommet en del nye ord og rettelser rapportert inn av de frivillige
1227 som gjennomfører korrektur av orddatabasen i prosjektet. For å få
1228 fortgang i dette korrekturarbeidet er det fint med flere frivillige
1229 som kan bidra i prosjektet.&lt;/p&gt;
1230
1231 &lt;p&gt;&lt;blockquote&gt;
1232 - En god og fritt tilgjengelig stavekontroll er en viktig byggestein
1233 for å fremme bruken av korrekt norsk språk, sier prosjektdeltager
1234 Petter Reinholdtsen.
1235 &lt;/blockquote&gt;&lt;/p&gt;
1236
1237 &lt;p&gt;Takket være samarbeidet med synonymordlisteprosjektet er
1238 synonymordlista for bokmål tilgjengelig sammen med ordlista for bokmål
1239 og nynorsk. En synonymordliste for nynorsk er også med, men den er på
1240 prøvestadiet og meget liten.&lt;/p&gt;
1241
1242 &lt;p&gt;Stavekontrollpakken og synonymordlistene brukes i
1243 LibreOffice/OpenOffice.org, Koffice, Mozilla Thunderbird, Firefox og
1244 en rekke andre programmer, og på både Windows, Mac OS X, Linux og
1245 BSD.&lt;/p&gt;
1246
1247 &lt;p&gt;Det hele utgis under den frie lisensen GPL og kan fritt lastes ned
1248 fra prosjektsidene på
1249 &lt;a href=&quot;http://no.speling.org&quot;&gt;no.speling.org&lt;/a&gt;. Ferdige pakker for
1250 LibreOffice/OpenOffice.org er også tilgjengelige fra samme sted.&lt;/p&gt;
1251
1252 &lt;p&gt;Det norske stavekontrollprosjektet er i kontakt med lignende
1253 prosjekter for blant annet å forbedre stavekontrollteknologien, å
1254 utveksle verktøy for vedlikehold av orddatabasen og å få tilgang til
1255 relevante datasett. Et av disse prosjektene er et separat prosjekt ved
1256 Sametinget som er i gang med å utvikle samisk stavekontroll for blant
1257 annet Microsoft Word og OpenOffice.org.&lt;/p&gt;
1258
1259 &lt;p&gt;Et søsterprosjekt for å lage grammatikk-kontroll for
1260 LibreOffice/OpenOffice.org er igangsatt, men har ennå ikke kommet
1261 langt nok til å brukes. Frivillige til å bidra i dette prosjektet er
1262 også svært velkomne.&lt;/p&gt;

1296 no longer work. This require the libmythes-dev package on Debian.&lt;/li&gt;
1297 &lt;li&gt;Introduce new Makefile variables hyphendir and thesdir to make it easier to
1298 control where to install these.&lt;/li&gt;
1299 &lt;li&gt;Change script used to import from no.speling.org, to load new word
1300 boundaries if at least two people believed the boundaries was correct.&lt;/li&gt;
1301 &lt;li&gt;Added word boundaries for several words (around 500 words) using the
1302 updated script.&lt;/li&gt;
1303 &lt;li&gt;Imported thesarus for bokmål from synonymer.merg.net.&lt;/li&gt;
1304 &lt;li&gt;Rewrote build rules to use = instead of - as combined word marker, thus
1305 allowing words like e-post.&lt;/li&gt;
1306 &lt;li&gt;Imported a lot (around 10k words) of new words with dash (-) in them from
1307 no.speling.org now that it is handled by the build system.&lt;/li&gt;

1313 <title>Debian Edu interview: Giorgio Pioda</title>
1314 <link>http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Giorgio_Pioda.html</link>
1315 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Giorgio_Pioda.html</guid>
1316 <pubDate>Mon, 17 Sep 2012 14:10:00 +0200</pubDate>
1317 <description>&lt;p&gt;After a long break in my row of interviews with people in the
1318 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu and Skolelinux&lt;/a&gt;
1319 community, I finally found time to wrap up another. This time it is
1320 Giorgio Pioda, which showed up on the mailing list at the start of
1321 this year, asking questions and inspiring us to improve the first time
1322 administrators experience with Skolelinux. :) The interview was
1323 conduced in May, but I only found time to publish it now.&lt;/p&gt;
1324
1325 &lt;p&gt;&lt;strong&gt;Who are you, and how do you spend your days?&lt;/strong&gt;&lt;/p&gt;
1326
1327 &lt;p&gt;I have a PhD in chemistry but since several years I work as teacher
1328 in secondary (15-18 year old students) and tertiary (a kind of &quot;light&quot;
1329 university) schools. Five years ago I started to manage a Learning
1330 Management Service server and slowly I got more and more involved with
1331 IT. 3 years ago the graduating schools moved completely to Linux and I
1332 got the head of the IT for this. The experience collected in chemistry
1333 labs computers (for example NMR analysis of protein folding) and in
1334 the IT-courses during university where sufficient to start. Self
1335 training is anyway very important&lt;/p&gt;
1336
1337 &lt;p&gt;I live in the Italian speaking part of Switzerland, and the
1338 &lt;a href=&quot;http://www.spse.ch/&quot;&gt;SPSE school&lt;/a&gt; (secondary) is a very
1339 special sport school for young people who try to became sport pro (for
1340 all sports, we have dozens of disciplines represented) and we are
1341 recognised by the Olympic Swiss Organisation.
1342
1343 &lt;p&gt;&lt;strong&gt;How did you get in contact with the Skolelinux/Debian Edu
1344 project?&lt;/strong&gt;&lt;/p&gt;
1345
1346 &lt;p&gt;Looking for Linux / Primary Domain Controller (PDC) I found it
1347 already several years ago. But since the system was still not
1348 Kerberized and since our schools relies strongly on laptops I didn&#39;t
1349 use it. I plan to introduce it in the next future, probably for the
1350 next school year, since the squeeze release solved this security
1351 hole.&lt;/p&gt;
1352
1353 &lt;p&gt;&lt;strong&gt;What do you see as the advantages of Skolelinux/Debian
1354 Edu?&lt;/strong&gt;&lt;/p&gt;
1355
1356 &lt;p&gt;Many. First of all there is a strong and living community that is
1357 very generous for help and hints. Chat help is crucial, together with
1358 the mailing list. Second. With Skolelinux you get an already well
1359 engineered platform and you don&#39;t have to start to build up your PDC
1360 and your clients from GNU/scratch; I&#39;ve already done this once and I
1361 can tell it, it is hard. Third, since Skolelinux is a standard
1362 platform, it is way easier to educate other IT people and even if the
1363 head IT is sick another one could pick up the task without too much
1364 hassle.&lt;/p&gt;
1365
1366 &lt;p&gt;&lt;strong&gt;What do you see as the disadvantages of Skolelinux/Debian
1367 Edu?&lt;/strong&gt;&lt;/p&gt;
1368
1369 &lt;p&gt;The only real problem I see is that it is a little too less
1370 flexible at client level. Debian stable is rocky and desirable, but
1371 there are many reasons that force for another choice. For example the
1372 need of new drivers for new PC, or the need for a specific OS for some
1373 devices that have specific software packages for another specific
1374 distribution (I have such a case for whiteboards that have only
1375 Ubuntu packages). Thus, I prepared compatibility packages educlient
1376 and eduroaming, hoping not to use them ;-)&lt;/p&gt;
1377
1378 &lt;p&gt;&lt;strong&gt;Which free software do you use daily?&lt;/strong&gt;&lt;/p&gt;
1379
1380 &lt;p&gt;I have a Debian Stable PDC at school (Kerberos, NIS, NFS) with
1381 mixed Debian and Ubuntu clients. If you think that this triad
1382 combination is exotic... well I discovered right yesterday that
1383 &lt;a href=&quot;http://moo.nac.uci.edu/~hjm/Perceus-Report.html&quot;&gt;Perceus&lt;/a&gt;
1384 has the same...&lt;/p&gt;
1385
1386 &lt;p&gt;For myself I run Debian wheezy/sid, but this combination is good
1387 only I you have enough competence to fix stuff for yourself, if
1388 something breaks. Daily I use texmacs, gnumeric, a little bit of R
1389 statistics, kmplot, and less frequently OpenOffice.org.&lt;/p&gt;
1390
1391 &lt;p&gt;&lt;strong&gt;Which strategy do you believe is the right one to use to
1392 get schools to use free software?&lt;/strong&gt;&lt;/p&gt;
1393
1394 &lt;P&gt;I think that the only real argument that school managers &quot;hear&quot; is
1395 cost reduction. They don&#39;t give too much weight on quality, stability,
1396 just because they are normally not open to change.&lt;/p&gt;
1397
1398 &lt;p&gt;Students adapts very quickly to GNU/Linux (and for them being able
1399 to switch between different OS is a plus value); teachers and managers
1400 don&#39;t.&lt;/p&gt;
1401
1402 &lt;p&gt;We decided to move to Linux because students at our school have own
1403 laptop and we have the responsibility to keep the laptop ready to use;
1404 we were really unsatisfied with Microsoft since every Monday we had 20
1405 machine to fix for viral infections... With Linux this has been
1406 reduced to zero, since people installs almost only from official
1407 repositories. I think that our special needs brought us to Linux.
1408 Those who don&#39;t have such needs will hardly move to Linux.&lt;/p&gt;

1415 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Gladoppslag_om_Skolelinux_i_avisen_Fremover.html</guid>
1416 <pubDate>Wed, 15 Aug 2012 10:20:00 +0200</pubDate>
1417 <description>&lt;p&gt;I sommer hadde avisen &lt;a href=&quot;http://www.fremover.no/&quot;&gt;Fremover&lt;/a&gt;
1418 et flott oppslag om bruken av
1419 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt; på alle skolene
1420 der. Artikkelen var på trykk på side 4 og 5 i papirutgaven
1421 2012-07-23, men mangler dessverre i nettutgaven av avisen. Mine
1422 henvendelser til avisen for å få artikkelen på nett har så langt ikke
1423 vært vellykket.&lt;/p&gt;
1424
1425 &lt;p&gt;Artikkelen med tittelen &quot;Narvik kommune bruker gratisprogram i
1426 skolen - Har spart millioner&quot;, forteller om hvordan bruken av
1427 Skolelinux er en stor suksess i Narvik siden det ble tatt i bruk i
1428 2004. Her er noen fine sitater:&lt;/p&gt;
1429
1430 &lt;blockquote&gt;
1431 &quot;- Skolelinux har spart kommunen for store pengesummer, millionbeløp,
1432 som de heller kan bruke på andre ting, sier IKT-konsulent Viggo
1433 Fedreheim.&quot;
1434 &lt;/blockquote&gt;
1435
1436 &lt;p&gt;Avisen forteller at de har fått tilgang til beregninger som viser
1437 at Narvik kommune har spart noe mellom 10 og 20 millioner kroner de
1438 siste 8 årene på å bruke Skolelinux, og fortsetter:&lt;/p&gt;
1439
1440 &lt;blockquote&gt;
1441
1442 &quot;Regnestykket tar høyde for sparte kostnader til lisenser som medfølger
1443 de alternative operativsystemene, lavere driftskostnader og lengre
1444 levetid på datautstyret. Totalt har Narvikskolen en maskinpark på
1445 1600 maskiner fordelt på de 11 skolene fra Skjomen i sør til Bjerkvik
1446 i nord.&quot;
1447
1448 &lt;/blockquote&gt;
1449
1450 &lt;p&gt;Viggo Fedreheim sier dette om hvor noe av gevinsten kommer fra:&lt;/p&gt;
1451
1452 &lt;blockquote&gt;
1453 &quot;- Vi kan gjenbruke gamle maskiner i skolen som er for dårlig andre
1454 steder i kommunen der de ikke bruker Skolelinux. Levetiden på en
1455 datamaskin blir 3-5 år lenger med Skolelinux. Vi kaller det for
1456 grønn IT, miljøvennlig IT.&quot;
1457 &lt;/blockquote&gt;
1458
1459 &lt;p&gt;Her er det mulighet for flere kommuner å få et godt IT-system på
1460 skolene, hvis de er villige til å forsøke. De som ikke har kompetanse
1461 innomhus kan kjøpe det fra en av de kommersielle leverandørene av
1462 Skolelinux-tjenester, som &lt;a href=&quot;http://www.slxdrift.no/&quot;&gt;Skolelinux
1463 Drift AS&lt;/a&gt; (der jeg er styremedlem). Komplett liste er tilgjengelig
1464 via
1465 &lt;a href=&quot;http://wiki.debian.org/DebianEdu/Help/ProfessionalHelp&quot;&gt;wikien&lt;/a&gt;.&lt;/p&gt;
1466
1467 &lt;p&gt;Update 2012-08-16: Today I was allowed by Fremover to put the PDF I
1468 received from them with a copy of the article on the Internet. It is
1469 &lt;a href=&quot;http://ftp.skolelinux.org/skolelinux/press/2012-07-23-fremover-narvik.pdf&quot;&gt;now
1470 available&lt;/a&gt; in the Skolelinux press archive.&lt;/p&gt;

1479 <description>&lt;p&gt;Jeg fikk nettopp spørsmål på epost om Skolelinux-prosjektet lever
1480 fra en som var interessert i å bidra, og måtte jo konstatere at i og
1481 med at spørsmålet ble stilt har prosjektet ikke lyktes med å formidle
1482 sin aktivitet. Her er det jeg svarte:&lt;/p&gt;
1483
1484 &lt;p&gt;&lt;blockquote&gt;
1485 &lt;p&gt;Jada, &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux-prosjektet&lt;/a&gt;
1486 lever, men det meste av utvikling foregår nå under paraplyen
1487 &lt;a href=&quot;http://wiki.debian.org/DebianEdu/&quot;&gt;Debian Edu&lt;/a&gt; som er det
1488 internasjonale navnet på prosjektet. Dugnaden i Norge organiseres av
1489 medlemsforeningen
1490 &lt;a href=&quot;http://www.friprogramvareiskolen.no/&quot;&gt;Fri programvare i
1491 Skolen&lt;/a&gt;, og det finnes minst ett selskap som selger kommersiell
1492 support på løsningen (&lt;a href=&quot;http://www.slxdrift.no/&quot;&gt;Skolelinux
1493 Drift AS&lt;/a&gt;, der jeg er styremedlem). Anbefaler at du melder deg på
1494 epostlisten
1495 &lt;a href=&quot;http://lists.debian.org/debian-edu/&quot;&gt;debian-edu@lists.debian.org&lt;/a&gt;
1496 (og debian-edu-announce) og
1497 &lt;a href=&quot;http://medlem.friprogramvareiskolen.no/&quot;&gt;melder deg inn i
1498 foreningen&lt;/a&gt; for å få beskjed om aktivitet som planlegges. Det
1499 planlegges
1500 &lt;a href=&quot;http://www.friprogramvareiskolen.no/Gathering&quot;&gt;utviklersamlinger
1501 i august&lt;/a&gt; og utover høsten.&lt;/p&gt;
1502
1503 &lt;p&gt;Bidra gjerne med å spre ordet om Skolelinux. Det er alt for få som
1504 bidrar til pressedekning, bloggposter, twittermeldinger, etc. :)&lt;/p&gt;
1505
1506 &lt;p&gt;Jeg antar du har funnet
1507 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/tags/intervju/&quot;&gt;bloggserien
1508 min med intervjuer&lt;/a&gt;. Det er antagelig også interessant for deg å
1509 følge med på &lt;a href=&quot;http://planet.skolelinux.org/&quot;&gt;Planet
1510 Skolelinux&lt;/a&gt;.&lt;/p&gt;
1511
1512 &lt;p&gt;Hm, jeg burde vel blogge alle disse lenkene slik at de blir enklere
1513 å finne...&lt;/p&gt;
1514 &lt;/blockquote&gt;&lt;/p&gt;
1515 &lt;p&gt;Herved gjort. :)&lt;/p&gt;

1520 <title>Debian Edu interview: George Bredberg</title>
1521 <link>http://people.skolelinux.org/pere/blog/Debian_Edu_interview__George_Bredberg.html</link>
1522 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Debian_Edu_interview__George_Bredberg.html</guid>
1523 <pubDate>Mon, 9 Jul 2012 00:30:00 +0200</pubDate>
1524 <description>&lt;p&gt;The &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu /
1525 Skolelinux&lt;/a&gt; project have users all over the globe, but until
1526 recently we have not known about any users in Norway&#39;s neighbour
1527 country Sweden. This changed when George Bredberg showed up in March
1528 this year on the mailing list, asking interesting questions about how
1529 to adjust and scale the just released
1530 &lt;a href=&quot;http://www.debian.org/News/2012/20120311.html&quot;&gt;Debian Edu
1531 Wheezy&lt;/a&gt; setup to his liking. He granted me an interview, and I am
1532 happy to share his answers with you here.&lt;/p&gt;
1533
1534 &lt;p&gt;&lt;strong&gt;Who are you, and how do you spend your days?&lt;/strong&gt;&lt;/p&gt;
1535
1536 &lt;p&gt;I&#39;m a 44 year old country guy that have been working 12 years at
1537 the same school as 50% IT-manager and 50% Teacher. My educational
1538 background is fil.kand in history and religious beliefs, an exam as a
1539 &quot;folkhighschool&quot; teacher, that is, for teaching grownups. In
1540 Norwegian I believe it&#39;s called &quot;Vuxenupplaring&quot;. I also have a master
1541 in &quot;Technology and social change&quot;. So I&#39;m not really a tech guy, I
1542 just like to study how humans and technology interact and that is my
1543 perspective when working with IT.&lt;/p&gt;
1544
1545 &lt;p&gt;&lt;strong&gt;How did you get in contact with the Skolelinux/Debian Edu
1546 project?&lt;/strong&gt;&lt;/p&gt;
1547
1548 I have followed the Skolelinux project for quite some time by
1549 now. Earlier I tested out the K12-LTSP project, which we used for some
1550 time, but I really like the idea of having a distribution aimed to be
1551 a complete solution for schools with necessary tools integrated. When
1552 K12-LTSP abandoned that idea some years ago, I started to look more
1553 seriously into Skolelinux instead.
1554
1555 &lt;p&gt;&lt;strong&gt;What do you see as the advantages of Skolelinux/Debian
1556 Edu?&lt;/strong&gt;&lt;/p&gt;
1557
1558 The big point of Skolelinux to me is that it is a complete
1559 distribution, ready to install. It has LDAP-support, MS Windows
1560 integration tools and so forth already configured, saving an
1561 administrator a lot of time and headache. We were using another Linux
1562 based thin-client system called Thinlinc, that has served us very
1563 well. But that Skolelinux is based on VNC and LTSP, to me, is better
1564 when it comes to the kind of multimedia used in schools. That is
1565 showing videos from Youtube or educational TV. It is also easier to
1566 mix thin clients with workstations, since the user settings will be the
1567 same. In our VNC-based solution you had to &quot;beat around the bush&quot; by
1568 setting up a second, hidden, home-directory for user settings for the
1569 workstations, because they will be different from the ones used on the
1570 thin clients. Skolelinux support for diskless workstations are very
1571 convenient since a school today often need to use a class room
1572 projector showing videos in full screen. That is easily done with a
1573 small integrated media computer running as a diskless workstation. You
1574 have only two installs to update and configure. One for the thin
1575 clients and one for the workstations. Also saving a lot of time. Our
1576 old system was also based on Redhat and CentOS. They are both very
1577 nice distributions, but they are sometimes painfully slow when it
1578 comes to updating multimedia support and multimedia programs (even
1579 such as Gimp), leaving us with a bit &quot;oldish&quot; applications. Debian is
1580 quicker to update.
1581
1582 &lt;p&gt;&lt;strong&gt;What do you see as the disadvantages of Skolelinux/Debian
1583 Edu?&lt;/strong&gt;&lt;/p&gt;
1584
1585 &lt;p&gt;Debian is a bit too quick when it comes to updating. As an example
1586 we use old HP terminals as thinclients, and two times already this
1587 year (2012) the updates you get from the repositories has stopped
1588 sound from working with them. It&#39;s a kernel/ALSA issue. So you have
1589 to be more careful properly testing the updates before you run them in
1590 a production environment. This has never happened with CentOS.&lt;/p&gt;
1591
1592 &lt;p&gt;I also would like to be able to set my own domain-settings at
1593 install time. In Skolelinux they are kind of hard coded into the
1594 distribution, when it comes to LDAP and at least samba integration.
1595 That is more a cosmetic/translation issue, and not a real problem.
1596 Running MS Windows applications within the Skolelinux environment needs
1597 to be better supported. That is, running them seamlessly via RDP, and
1598 support for single-sign on. That will make the transition to free
1599 software easier, because you can keep the applications you really
1600 need. No support will make it impossible if you work in a school where
1601 some applications can&#39;t be open source. As for us we really need to
1602 run Adobe InDesign in our journalist classes. We run a journalist
1603 education, and is one of the very few non university ones that is ok:d
1604 by Svenska journalistförbundet (Swedish journalist association). Our
1605 education gives the pupils the right of membership there, once they
1606 are done. This is important if you want to get a job.&lt;/p&gt;
1607
1608 &lt;p&gt;Adobe InDesign is the program most commonly used in newspapers and
1609 magazines. We used Quark Express before, but they seem to loose there
1610 market to Adobe. The only &quot;equivalent&quot; to InDesign in the opensource
1611 world is Scribus, and its not advanced enough. At least not according
1612 to the teacher. I think it would be possible to use it, because they
1613 are not supposed to learn a program, they are supposed to learn how to
1614 edit and compile a newspaper. But politically at our school we are not
1615 there yet. And Scribus lacks a lot of things you find i InDesign.&lt;/p&gt;
1616
1617 &lt;p&gt;We used even a windows program for sound editing when it comes to
1618 the radio-journalist part. The year to come we are going to try
1619 Audacity. That software has the same kind of limitations compared to
1620 Adobe Audition, but that teacher is a bit more open minded. We have
1621 tried Ardour also, but that instead is more like a music studio
1622 program, not intended for the kind of editing taking place in a radio
1623 studio. Its way to complex and the GUI is to scattered when you only
1624 want to cut, make pass-overs, add extra channels and normalise. Those
1625 things you can do in Audacity, but its not as easy as in Audition. You
1626 have to do more things manually with envelopes, and that is a bit old
1627 fashion and timewasting. Its also harder to cut and move sound from
1628 one channel to another, which is a thing that you do frequently
1629 because you often find yourself needing to rearrange parts of the
1630 sound file.&lt;/p&gt;
1631
1632 &lt;p&gt;So, I am not sure we will succeed in replacing even Audition, but we
1633 will try. The problem is the students have certain expectations when
1634 they start an education towards a profession. So the programs has to
1635 look and feel professional. Good thing with radio, there are many
1636 programs out there, that radio studios use, so its not as standardised
1637 as Newspaper editing. That means, it does not really matter what
1638 program they learn, because once they start working they still have to
1639 learn the program the studio uses, so instead focus has to be to learn
1640 the editing part without to much focus on a specific software.&lt;/p&gt;
1641
1642 &lt;p&gt;&lt;strong&gt;Which free software do you use daily?&lt;/strong&gt;&lt;/p&gt;
1643
1644 &lt;p&gt;Myself I&#39;m running Linux Mint, or Ubuntu these days. I use almost
1645 only open source software, and preferably Linux based. When it comes
1646 to most used applications its OpenOffice, and Firefox (of course ;)
1647 )&lt;/p&gt;
1648
1649 &lt;p&gt;&lt;strong&gt;Which strategy do you believe is the right one to use to
1650 get schools to use free software?&lt;/strong&gt;&lt;/p&gt;
1651
1652 &lt;p&gt;To get schools to use free software there has to be good open
1653 source software that are windows based, to ease the transition. But
1654 it&#39;s also very important that the multimedia support is working
1655 flawlessly. The problems with Youtube, Twitter, Facebook and whatever
1656 will create problems when it comes to both teachers and
1657 students. Economy are also important for schools, so using thin
1658 clients, as long as they have good multimedia support, is a very good
1659 idea. It&#39;s also important that the open source software works even for
1660 the administration. It&#39;s hard to convince the teachers to stick with
1661 open source, if the principal has to run Windows. It also creates a
1662 problem if some classes has to use Windows for there tasks, since that
1663 will create a difference in &quot;status&quot; between classes, so a good
1664 support for running windows applications via the thin client (Linux)
1665 desktop is essential. At least at our school, where we have mixed
1666 level of educations, from high-school to journalist-school.&lt;/p&gt;
1667
1668 &lt;p&gt;Update 2012-07-09 08:30: Paul Wise tipped me on IRC about three
1669 useful sources related to Free Software for radio stations: the LWN
1670 article &lt;a href=&quot;https://lwn.net/Articles/481607/&quot;&gt;Radio station
1671 management with Airtime&lt;/a&gt;,
1672 &lt;a href=&quot;http://www.sourcefabric.org/en/airtime/&quot;&gt;Airtime&lt;/a&gt; which
1673 claim to be a Free open source radio automation software and
1674 &lt;a href=&quot;http://www.rivendellaudio.org/&quot;&gt;Rivendell&lt;/a&gt; which claim to
1675 be complete radio broadcast automation solution. All of them seem
1676 useful to the aspiring radio producer.&lt;/p&gt;

1681 <title>Why do schools waste money on IT?</title>

1683 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Why_do_schools_waste_money_on_IT_.html</guid>
1684 <pubDate>Sun, 8 Jul 2012 09:40:00 +0200</pubDate>
1685 <description>&lt;p&gt;In the Debian Edu / Skolelinux project, we have realised that one
1686 of the major blockers for the project success is the purchasing skills
1687 in schools and municipalities. We provide what the happy users of
1688 Debian Edu / Skolelinux say they need and to a lower cost than the
1689 alternatives, and yet so few schools decide to use our solution. I
1690 was pleased to discover the same observation done by mySociety and Tom
1691 Steinberg in his blog post
1692 &quot;&lt;a href=&quot;http://www.mysociety.org/2012/06/19/can-you-recognize-the-million-pound-chair/&quot;&gt;Can
1693 you recognize the million pound chair?&lt;/a&gt;&quot;. Read it and weep for the
1694 spending of your tax money.&lt;/p&gt;
1695
1696 &lt;p&gt;Of course there are other factors involved as well, like our
1697 projects bad marketing skills and the Linux community fragmentation
1698 causing worry with the people on the outside, so we as a project need
1699 to keep working hard to gain users, but it is a up-hill battle when
1700 public decision makers are unable to understand computer system
1701 purchases.&lt;/p&gt;

1710 <description>&lt;p&gt;Included in &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu /
1711 Skolelinux&lt;/a&gt; is a large collection of end user and school specific
1712 software. It is one of the packages not installed by default but
1713 provided in the Debian archive for schools to install if they want to,
1714 is a system to automatically plan the school time table using
1715 information about available teachers, classes and rooms, combined with
1716 the list of required courses and how many hours each topic should
1717 receive. The software is
1718
1719 &lt;a href=&quot;http://lalescu.ro/liviu/fet/&quot;&gt;named FET&lt;/a&gt;, and it provide a
1720 graphical user interface to input the required information, save the
1721 result in a fairly simple XML format, and generate time tables for
1722 both teachers and students. It is available both for
1723 &lt;a href=&quot;http://lalescu.ro/liviu/fet/download.html&quot;&gt;Linux, MacOSX and
1724 Windows&lt;/a&gt;.&lt;/p&gt;

1741 (Uzbek) and vi (Vietnamese) (incompletely for some languages)
1742 &lt;/li&gt;
1743
1744 &lt;li&gt;Fully automatic generation algorithm, allowing also
1745 semi-automatic or manual allocation&lt;/li&gt;
1746
1747 &lt;li&gt;Platform independent implementation, allowing running on
1748 GNU/Linux, Windows, Mac and any system that Qt supports &lt;/li&gt;
1749
1750 &lt;li&gt;Flexible modular XML format for the input file, allowing editing
1751 with an XML editor or by hand (besides FET interface)&lt;/li&gt;
1752
1753 &lt;li&gt;Import/export from CSV format&lt;/li&gt;
1754
1755 &lt;li&gt;The resulted timetables are exported into HTML, XML and CSV
1756 formats &lt;/li&gt;
1757
1758 &lt;li&gt;Flexible students structure, organized into sets: years, groups
1759 and subgroups. FET allows overlapping years and groups and
1760 non-overlapping subgroups. You can even define individual students
1761 (as separate sets)&lt;/li&gt;
1762
1763 &lt;li&gt;Each constraint has a weight percentage, from 0.0% to 100.0%
1764 (but some special constraints are allowed to have only 100% weight
1765 percentage)&lt;/li&gt;
1766
1767 &lt;li&gt;Limits for the algorithm (all these limits can be increased on
1768 demand, as a custom version, because this would require a bit more
1769 memory):
1770 &lt;ul&gt;
1771 &lt;li&gt;Maximum total number of hours (periods) per day: 60&lt;/li&gt;
1772 &lt;li&gt;Maximum number of working days per week: 35&lt;/li&gt;
1773 &lt;li&gt;Maximum total number of teachers: 6000&lt;/li&gt;
1774 &lt;li&gt;Maximum total number of sets of students: 30000&lt;/li&gt;
1775 &lt;li&gt;Maximum total number of subjects: 6000&lt;/li&gt;
1776 &lt;li&gt;Virtually unlimited number of activity tags&lt;/li&gt;
1777 &lt;li&gt;Maximum number of activities: 30000&lt;/li&gt;
1778 &lt;li&gt;Maximum number of rooms: 6000&lt;/li&gt;
1779 &lt;li&gt;Maximum number of buildings: 6000&lt;/li&gt;
1780 &lt;li&gt;Possibility of adding multiple teachers and
1781 students sets for each activity. (it is possible
1782 also to have no teachers or no students sets for an
1783 activity)&lt;/li&gt;
1784 &lt;li&gt;Virtually unlimited number of time constraints&lt;/li&gt;
1785 &lt;li&gt;Virtually unlimited number of space constraints&lt;/li&gt;
1786 &lt;/ul&gt;&lt;/li&gt;
1787
1788 &lt;li&gt;A large and flexible palette of time constraints:
1789 &lt;ul&gt;
1790 &lt;li&gt;Break periods&lt;/li&gt;
1791 &lt;li&gt;For teacher(s):
1792 &lt;ul&gt;
1793 &lt;li&gt;Not available periods&lt;/li&gt;
1794 &lt;li&gt;Max/min days per week&lt;/li&gt;
1795 &lt;li&gt;Max gaps per day/week&lt;/li&gt;
1796 &lt;li&gt;Max hours daily/continuously&lt;/li&gt;
1797 &lt;li&gt;Min hours daily&lt;/li&gt;
1798 &lt;li&gt;Max hours daily/continuously with an activity tag&lt;/li&gt;
1799
1800 &lt;li&gt;Respect working in an hourly interval a max number of
1801 days per week&lt;/li&gt;
1802 &lt;/ul&gt;&lt;/li&gt;
1803 &lt;li&gt;For students (sets):
1804 &lt;ul&gt;
1805 &lt;li&gt;Not available periods&lt;/li&gt;
1806 &lt;li&gt;Begins early (specify max allowed beginnings at second hour)&lt;/li&gt;
1807 &lt;li&gt;Max gaps per day/week&lt;/li&gt;
1808 &lt;li&gt;Max hours daily/continuously&lt;/li&gt;
1809 &lt;li&gt;Min hours daily&lt;/li&gt;
1810 &lt;li&gt;Max hours daily/continuously with an activity tag&lt;/li&gt;
1811
1812 &lt;li&gt;Respect working in an hourly interval a max number of
1813 days per week&lt;/li&gt;
1814 &lt;/ul&gt;&lt;/li&gt;
1815 &lt;li&gt;For an activity or a set of activities/subactivities:
1816 &lt;ul&gt;
1817 &lt;li&gt;A single preferred starting time&lt;/li&gt;
1818 &lt;li&gt;A set of preferred starting times&lt;/li&gt;
1819 &lt;li&gt;A set of preferred time slots&lt;/li&gt;
1820 &lt;li&gt;Min/max days between them&lt;/li&gt;
1821 &lt;li&gt;End(s) students day&lt;/li&gt;
1822 &lt;li&gt;Same starting time/day/hour&lt;/li&gt;
1823 &lt;li&gt;Occupy max time slots from selection (a complex and
1824 flexible constraint, useful in many situations)&lt;/li&gt;
1825 &lt;li&gt;Consecutive, ordered, grouped (for 2 or 3 (sub)activities)&lt;/li&gt;
1826 &lt;li&gt;Not overlapping&lt;/li&gt;
1827 &lt;li&gt;Max simultaneous in selected time slots&lt;/li&gt;
1828 &lt;li&gt;Min gaps between a set of (sub)activities&lt;/li&gt;
1829 &lt;/ul&gt;&lt;/li&gt;
1830 &lt;/ul&gt;&lt;/li&gt;
1831
1832 &lt;li&gt;A large and flexible palette of space constraints:
1833 &lt;ul&gt;
1834 &lt;li&gt;Room not available periods&lt;/li&gt;
1835 &lt;li&gt;For teacher(s):
1836 &lt;ul&gt;
1837 &lt;li&gt;Home room(s)&lt;/li&gt;
1838 &lt;li&gt;Max building changes per day/week&lt;/li&gt;
1839 &lt;li&gt;Min gaps between building changes&lt;/li&gt;
1840 &lt;/ul&gt;
1841 &lt;/li&gt;
1842
1843 &lt;li&gt;For students (sets):
1844 &lt;ul&gt;
1845 &lt;li&gt;Home room(s)&lt;/li&gt;
1846 &lt;li&gt;Max building changes per day/week&lt;/li&gt;
1847 &lt;li&gt;Min gaps between building changes&lt;/li&gt;
1848 &lt;/ul&gt;
1849 &lt;/li&gt;
1850 &lt;li&gt;Preferred room(s):
1851 &lt;ul&gt;
1852 &lt;li&gt;For a subject&lt;/li&gt;
1853 &lt;li&gt;For an activity tag&lt;/li&gt;
1854 &lt;li&gt;For a subject and an activity tag&lt;/li&gt;
1855 &lt;li&gt;Individually for a (sub)activity&lt;/li&gt;
1856 &lt;/ul&gt;
1857 &lt;/li&gt;
1858
1859 &lt;li&gt;For a set of activities:
1860 &lt;ul&gt;
1861 &lt;li&gt;Occupy a maximum number of different rooms&lt;/li&gt;
1862 &lt;/ul&gt;
1863 &lt;/li&gt;
1864 &lt;/ul&gt;
1865 &lt;/li&gt;
1866 &lt;/ul&gt;&lt;/p&gt;
1867
1868 &lt;p&gt;I have not used it myself, as I am not involved in time table
1869 planning at a school, but it seem to work fine when I test it. If you
1870 need to set up your schools time table, and is tired of doing it
1871 manually, check it out.
1872
1873 A quick summary on how to use it can be found in
1874 &lt;a href=&quot;http://marvelsoft.co.in/wp/2012/03/generate-timetable-for-state-cbse-icse-igcse-schools-free/&quot;&gt;a
1875 blog post from MarvelSoft&lt;/a&gt;. If you find FET useful, please provide
1876 a recipe for the Debian Edu project in the

1885 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Skolelinux_intervju__Markus_Gamenius.html</guid>
1886 <pubDate>Sat, 30 Jun 2012 12:50:00 +0200</pubDate>
1887 <description>&lt;p&gt;Tidligere leder av
1888 &lt;a href=&quot;http://www.friprogramvareiskolen.no&quot;&gt;foreningen som
1889 organiserer Skolelinux-dugnaden&lt;/a&gt;, Markus Gamenius , har i vår vært
1890 i media og
1891 &lt;a href=&quot;http://www.dn.no/privatokonomi/article2345489.ece&quot;&gt;debattert
1892 skattepolitikk&lt;/a&gt;, og det fikk meg til å høre om han kunne lokkes til
1893 å fortelle om hans inntrykk nå, etter at han ble lokket bort fra
1894 Linux- og &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt;-verden
1895 for å overta familiebedriften. Her har vi hans betraktninger i dag,
1896 noen måneder etter at
1897 &lt;a href=&quot;http://www.debian.org/News/2012/20120311.html&quot;&gt;Skolelinux
1898 Squeeze&lt;/a&gt;-utgaven ble gitt ut.&lt;/p&gt;
1899
1900 &lt;p&gt;&lt;strong&gt;Hvem er du, og hva driver du med til daglig?&lt;/strong&gt;&lt;/p&gt;
1901
1902 &lt;p&gt;Jeg heter Markus Gamenius og er 40 år. Utdannet biolog med ymse
1903 fag på siden. Har jobbet som lærer der jeg var driftsansvarlig på
1904 Ulsrud VGS i Oslo. Senere eide og jobbet jeg flere år i Linuxlabs AS,
1905 som jeg solgte til Redpill Linpro AS (den gangen Linpro AS). I dag
1906 jobber jeg med ulike investeringer, hovedsaklig i eiendom, men også i
1907 en del ulike IT-relaterte bedrifter.&lt;/p&gt;
1908
1909 &lt;p&gt;&lt;strong&gt;Hvordan kom du i kontakt med Skolelinux-prosjektet?&lt;/strong&gt;&lt;/p&gt;
1910
1911 &lt;p&gt;Fruen og jeg dro på en lengre seiltur i 2000, der jeg måtte ha &quot;noe
1912 å gjøre&quot; under hjemturen over Atlanteren. Jeg kjøpte et par bøker om
1913 Linux i en bokhandel i New York og ble veldig fascinert. Etter
1914 hjemkomsten begynte jeg å jobbe på Ulsrud VGS, som naturfagslærer, men
1915 som IT-interessert ble jeg fort en del av den nye IT-satsningen som
1916 skulle løfte Ulsrud og gi skolen en bedre rykte. Vi hadde ganske
1917 mange maskiner, som gikk på Win98 og to servere som ble oppgradert til
1918 Win2000. Systemene var ustabil og dårlige. På leting etter noe
1919 bedre, uten å knekke ryggen økonomisk, kom jeg over &quot;Linux i Skolen&quot;
1920 og Skolelinux. Jeg tok kontakt med miljøet og en gjeng møtte opp på
1921 skolen, der vi gjorde en liten testinstallasjon. Etter et par år var
1922 ryggraden på skolen Linux (Skolelinux) og vi hadde flere hundre
1923 maskiner, både tynne klienter (gamle og nye), bærbare (Debian) og noen
1924 stasjonære (Win2000). På et tidspunkt var Ulsrud den råeste IT-skolen
1925 og det irriterte skolesjefen i Oslo, da de satset hardt på
1926 Windows.&lt;/p&gt;
1927
1928 &lt;p&gt;&lt;strong&gt;Hva er fordelene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
1929
1930 &lt;p&gt;Det som gjorde at vi fikk inn Skolelinux var ene og alene
1931 økonomiske. Det faktum at vi slapp å kjøpe masse nye lisenser og at
1932 vi kunne bruke gammel hardware. Alt i alt gjorde dette at vi sparte
1933 mye, men i stede for å bruke mindre på IT brukte vi det vi sparte på å
1934 skaffe mer hardware og på den måten gi det beste tilbudet i landet til
1935 våre elever. For oss som driftet var det himmel å ha et system som
1936 gikk å administrere sentralt og effektivt. Det var heller ikke så
1937 dumt at vi kunne &quot;låse&quot; maskinene mer effektivt enn vi kunne med
1938 Microsoft Windows, slik at vi slapp mye feil og problemer som ble
1939 forårsaket av &quot;kreative&quot; elever.&lt;/p&gt;
1940
1941 &lt;p&gt;&lt;strong&gt;Hva er ulempene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
1942
1943 &lt;p&gt;Det vi slet med var mangelen av en del programmer lærerne ville ha.
1944 Husker ikke alle, men det var et knippe med pedagogiske programmer de
1945 ikke fikk. I dag tror jeg det problemet er langt mindre da det meste
1946 av disse kjøres gjennom nettleseren.&lt;/p&gt;
1947
1948 &lt;p&gt;&lt;strong&gt;Hvilken fri programvare bruker du til daglig?&lt;/strong&gt;&lt;/p&gt;
1949
1950 &lt;p&gt;Jeg bruker mye Apple i dag og er ikke så stolt av det, men jeg har
1951 både OpenOffice, Firefox og en del andre programmer på den bærbare.
1952 Firefox brukes mest av disse. På Apple-serveren hjemme bruker jeg
1953 HandBrake mye, og jeg har installert OpenWRT på flere av
1954 basestasjonene både hjemme og på jobben. I tillegg til det har jeg i
1955 flere år finansiert et prosjekt som heter
1956 &lt;a href=&quot;http://www.found.no/&quot;&gt;Found IT&lt;/a&gt;. Dette er et prosjekt der
1957 vi lager et rammeverk for søk, der alt vi bruker fri programvare. Det
1958 er Alex Brasetvik som er daglig leder i Found IT.&lt;/p&gt;
1959
1960 &lt;p&gt;&lt;strong&gt;Hvilken strategi tror du er den rette å bruke for å få
1961 skoler til å ta i bruk fri programvare?&lt;/strong&gt;&lt;/p&gt;
1962
1963 &lt;p&gt;Når det gjelder IT og skole er fortsatt økonomi veldig viktig. Så
1964 man må oppfylle minimumskravene (ikke være best, men bra nok) og selge
1965 seg inn på hvor mye man sparer. Det betyr selvsagt at man sparer på
1966 lisenser, men også på driftsinnsats. Men nå når jeg ikke er en aktiv
1967 del av miljøet lenger hører jeg nesten ingen ting om fri programvare.
1968 Jeg stiller meg da spørsmålet om det har blitt stille rundt miljøet,
1969 eller om jeg kun så det tydeligere før når jeg var aktiv? Uansett er
1970 det for stille rundt Skolelinux-prosjektet nå.&lt;/p&gt;

1975 <title>Debian Edu interview: José Luis Redrejo Rodríguez</title>
1976 <link>http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Jos__Luis_Redrejo_Rodr_guez.html</link>
1977 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Jos__Luis_Redrejo_Rodr_guez.html</guid>
1978 <pubDate>Tue, 26 Jun 2012 08:30:00 +0200</pubDate>
1979 <description>&lt;p&gt;I&#39;ve been too busy at home, but finally I found time to wrap up
1980 another interview with the people behind
1981 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu and Skolelinux&lt;/a&gt;.
1982 This time we get to know José Luis Redrejo Rodríguez, one of our great
1983 helpers from Spain. His effort was the reason we added support for
1984 several desktop types (KDE, Gnome and most recently LXDE) in Debian
1985 Edu, and have all of these available in the recently published
1986 &lt;a href=&quot;http://www.debian.org/News/2012/20120311.html&quot;&gt;Debian Edu
1987 Squeeze&lt;/a&gt; version.&lt;/p&gt;
1988
1989 &lt;p&gt;&lt;strong&gt;Who are you, and how do you spend your days?&lt;/strong&gt;&lt;/p&gt;
1990
1991 &lt;p&gt;I&#39;m a father, teacher and engineer who is working for the Education
1992 ministry of the Region of Extremadura (Spain) in the implementation of
1993 ICT in schools&lt;/p&gt;
1994
1995 &lt;p&gt;&lt;strong&gt;How did you get in contact with the Skolelinux/Debian Edu
1996 project?&lt;/strong&gt;&lt;/p&gt;
1997
1998 &lt;p&gt;At 2006, I verified that both, we in Extremadura and Skolelinux
1999 project, had been working in parallel for some years, doing very
2000 similar things, using very similar tools and with similar targets, so
2001 I decided it was time to join forces as much as possible.&lt;/p&gt;
2002
2003 &lt;p&gt;&lt;strong&gt;What do you see as the advantages of Skolelinux/Debian
2004 Edu?&lt;/strong&gt;&lt;/p&gt;
2005
2006 &lt;p&gt;A community of highly skilled experts working together, with a
2007 really open schema of collaboration and work. I really love the
2008 concepts of Do-ocracy and Merit-ocracy and the way these concepts are
2009 been used everyday inside Debian Edu.&lt;/p&gt;
2010
2011 &lt;p&gt;&lt;strong&gt;What do you see as the disadvantages of Skolelinux/Debian
2012 Edu?&lt;/strong&gt;&lt;/p&gt;
2013
2014 &lt;p&gt;Sometimes the differences in the implementations, laws or
2015 economical and technical resources in the different countries don&#39;t
2016 allow us to agree in the same solution for all of us, and several
2017 approaches are needed, what is a waste of effort. Also, there is a
2018 lack of more man power to be able to follow the fast evolution of the
2019 technologies in school.&lt;/p&gt;
2020
2021 &lt;p&gt;&lt;strong&gt;Which free software do you use daily?&lt;/strong&gt;&lt;/p&gt;
2022
2023 &lt;p&gt;Debian, of course, and due to my kind of job I am most of my time
2024 between Iceweasel, &lt;a href=&quot;http://www.geany.org/&quot;&gt;Geany&lt;/a&gt; and
2025 &lt;a href=&quot;http://www.ohloh.net/p/gnome-terminator&quot;&gt;Terminator&lt;/a&gt;.&lt;/p&gt;
2026
2027 &lt;p&gt;&lt;strong&gt;Which strategy do you believe is the right one to use to
2028 get schools to use free software?&lt;/strong&gt;&lt;/p&gt;
2029
2030 &lt;p&gt;I think there is not a single strategy because there are very
2031 different scenarios: schools with mixed proprietary and free
2032 environments, schools using only workstations, other schools using
2033 laptops, netbooks, tablets, interactive white-boards, etc.&lt;/p&gt;
2034
2035 &lt;p&gt;Also the range of ages of the students is very broad and you can
2036 not use the same solutions for primary schools and secondary or even
2037 universities. So different strategies are needed.&lt;/p&gt;
2038
2039 &lt;p&gt;But, looking at these differences, and looking back to the things
2040 we&#39;ve done and implemented, and the places were we have spent most of
2041 our forces, I think we should focus as much as possible in free
2042 multi-platform environments, using only standards tools, and moving
2043 more and more to Internet or network solutions that could be deployed
2044 using wireless. I think we&#39;ll see more and more personal devices in
2045 the schools, devices the students and teachers will take home with
2046 them, so the solutions must be able to be taken at home and continue
2047 working there.&lt;/p&gt;

2052 <title>Debian Edu - some ideas for the future versions</title>
2053 <link>http://people.skolelinux.org/pere/blog/Debian_Edu___some_ideas_for_the_future_versions.html</link>
2054 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Debian_Edu___some_ideas_for_the_future_versions.html</guid>
2055 <pubDate>Mon, 11 Jun 2012 14:30:00 +0200</pubDate>
2056 <description>&lt;p&gt;During my work on
2057 &lt;a href=&quot;http://www.debian.org/News/2012/20120311.nb.html&quot;&gt;Debian Edu
2058 based on Squeeze&lt;/a&gt;, I came across some issues that should be
2059 addressed in the Wheezy release. I finally found time to wrap up my
2060 notes and provide quick summary of what I found, with a bit
2061 explanation.&lt;/p&gt;
2062
2063 &lt;p&gt;&lt;ul&gt;
2064
2065 &lt;li&gt;We need to rewrite our package installation framework, as tasksel
2066 changed from using tasksel tasks to using meta packages (aka packages
2067 with dependencies like our education-* packages), and our installation
2068 system depend on tasksel tasks in
2069 /usr/share/tasksel/debian-edu-tasks.desc for package
2070 installation.&lt;/li&gt;
2071
2072 &lt;li&gt;Enable Kerberos login for more services. Now with the Kerberos
2073 foundation in place, we should use it to get single sign on with more
2074 services, and avoiding unneeded password / login questions. We should
2075 at least try to enable it for these services:
2076 &lt;ul&gt;
2077
2078 &lt;li&gt;CUPS for admins to add/configure printers and users when using
2079 quotas.&lt;/li&gt;
2080 &lt;li&gt;Nagios for admins checking the system status.&lt;/li&gt;
2081 &lt;li&gt;GOsa for admins updating LDAP and users changing their passwords.&lt;/li&gt;
2082 &lt;li&gt;LDAP for admins updating LDAP.&lt;/li&gt;
2083 &lt;li&gt;Squid for users when exam mode / filtering is active.&lt;/li&gt;
2084 &lt;li&gt;ssh for admins and users to save a password prompt.&lt;/li&gt;
2085
2086 &lt;/ul&gt;&lt;/li&gt;
2087
2088 &lt;li&gt;When we move GOsa to use Kerberos instead of LDAP bind to
2089 authenticate users, we should try to block or at least limit access to
2090 use LDAP bind for authentication, to ensure Kerberos is used when it
2091 is intended, and nothing fall back to using the less safe LDAP bind&lt;/li&gt;
2092
2093 &lt;li&gt;Merge debian-edu-config and debian-edu-install. The split made
2094 sense when d-e-install did a lot more, but these days it is just an
2095 inconvenience when we update the debconf preseeding values.&lt;/li&gt;
2096
2097 &lt;li&gt;Fix partman-auto to allow us to abort the installation before
2098 touching the disk if the disk is too small. This is
2099 &lt;a href=&quot;http://bugs.debian.org/653305&quot;&gt;BTS report #653305&lt;/a&gt; and the
2100 d-i developers are fine with the patch and someone just need to apply
2101 it and upload. After this is done we need to adjust
2102 debian-edu-install to use this new hook.&lt;/li&gt;
2103
2104 &lt;li&gt;Adjust to new LTSP framework (boot time config instead of install
2105 time config). LTSP changed its design, and our hooks to install
2106 packages and update the configuration is most likely not going to work
2107 in Wheezy.
2108
2109 &lt;li&gt;Consider switching to NBD instead of NFS for LTSP root, to allow
2110 the Kernel to cache files in its normal file cache, possibly speeding
2111 up KDE login on slow networks.&lt;/li&gt;
2112
2113 &lt;li&gt;Make it possible to create expired user passwords that need to
2114 change on first login. This is useful when handing out password on
2115 paper, to make sure only the user know the password. This require
2116 fixes to the PAM handling of kdm and gdm.&lt;/li&gt;
2117
2118 &lt;li&gt;Make GUI for adding new machines automatically from sitesummary.
2119 The current command line script is not very friendly to people most
2120 familiar with GUIs. This should probably be integrated into GOsa to
2121 have it available where the admin will be looking for it..&lt;/li&gt;
2122
2123 &lt;li&gt;We should find way for Nagios to check that the DHCP service
2124 actually is working (as in handling out IP addresses). None of the
2125 Nagios checks I have found so far have been working for me.&lt;/li&gt;
2126
2127 &lt;li&gt;We should switch from libpam-nss-ldapd to sssd for all profiles
2128 using LDAP, and not only on for roaming workstations, to have less
2129 packages to configure and consistent setup across all profiles.&lt;/li&gt;
2130
2131 &lt;li&gt;We should configure Kerberos to update LDAP and Samba password
2132 when changing password using the Kerberos protocol. The hook was
2133 requested in &lt;a href=&quot;http://bugs.debian.org/588968&quot;&gt;BTS report
2134 #588968&lt;/a&gt; and is now available in Wheezy. We might need to write a
2135 MIT Kerberos plugin in C to get this.&lt;/li&gt;
2136
2137 &lt;li&gt;We should clean up the set of applications installed by default.
2138 &lt;ul&gt;
2139
2140 &lt;li&gt;reduce the number of chemistry visualisers&lt;/li&gt;
2141 &lt;li&gt;consider dropping xpaint&lt;/li&gt;
2142 &lt;li&gt;and probably more?&lt;/li&gt;
2143 &lt;/ul&gt;&lt;/li&gt;
2144
2145 &lt;li&gt;Some hardware need external firmware to work properly. This is
2146 mostly the case for WiFi network cards, but there are some other
2147 examples too. For popular laptops to work out of the box, such
2148 firmware need to be installed from non-free, and we should provide
2149 some GUI to do this. Ubuntu already have this implemented, and we
2150 could consider using their packages. At the moment we have some
2151 command line script to do this (one for the running system, another
2152 for the LTSP chroot).&lt;/li&gt;
2153
2154
2155 &lt;li&gt;In Squeeze, we provide KDE, Gnome and LXDE as desktop options. We
2156 should extend the list to Xfce and Sugar, and preferably find a way to
2157 install several and allow the admin or the user to select which one to
2158 use.&lt;/li&gt;
2159
2160 &lt;li&gt;The golearn tool from the goplay package make it easy to check out
2161 interesting educational packages. We should work on the package
2162 tagging in Debian to ensure it represent all the useful educational
2163 packages, and extend the tool to allow it to use packagekit to install
2164 new applications with a simple mouse click.&lt;/li&gt;
2165
2166 &lt;li&gt;The Squeeze version got half a exam solution already in place,
2167 with the introduction of iptable based network blocking, but for it to
2168 be a complete exam solution the Squid proxy need to enable
2169 filtering/blocking as well when the exam mode is enabled. We should
2170 implement a way to easily enable this for the schools that want it,
2171 instead of the &quot;it is documented&quot; method of today.&lt;/li&gt;
2172
2173 &lt;li&gt;A feature used in several schools is the ability for a teacher to
2174 &quot;take over&quot; the desktop of individual or all computers in the room.
2175 There are at least three implementations,
2176 &lt;a href=&quot;italc.sourceforge.net/&quot;&gt;italc&lt;/a&gt;,
2177 &lt;a href=&quot;http://www.itais.net/help/en/&quot;&gt;controlaula&lt;/a&gt; og
2178 &lt;a href=&quot;http://www.epoptes.org/&quot;&gt;epoptes&lt;/a&gt; and we should pick one of
2179 them and make it trivial to set it up in a school. The challenges is
2180 how to distribute crypto keys and how to group computers in one room
2181 and how to set up which machine/user can control the machines in a
2182 given room.&lt;/li&gt;
2183
2184 &lt;li&gt;Tablets and surf boards are getting more and more popular, and we
2185 should look into providing a good solution for integrating these into
2186 the Debian Edu network. Not quite sure how. Perhaps we should
2187 provide a installation profile with better touch screen support for
2188 them, or add some sync services to allow them to exchange
2189 configuration and data with the central server. This should be
2190 investigated.&lt;/li&gt;
2191
2192 &lt;/ul&gt;&lt;/p&gt;
2193
2194 &lt;p&gt;I guess we will discover more as we continue to work on the Wheezy
2195 version.&lt;/p&gt;

2200 <title>Debian Edu interview: Mike Gabriel</title>
2201 <link>http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Mike_Gabriel.html</link>
2202 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Mike_Gabriel.html</guid>
2203 <pubDate>Sat, 2 Jun 2012 15:00:00 +0200</pubDate>
2204 <description>&lt;p&gt;Back in 2010, Mike Gabriel showed up on the
2205 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu and Skolelinux&lt;/a&gt;
2206 mailing list. He quickly proved to be a valuable developer, and
2207 thanks to his tireless effort we now have Kerberos integrated into the
2208 &lt;a href=&quot;http://www.debian.org/News/2012/20120311.html&quot;&gt;Debian Edu
2209 Squeeze&lt;/a&gt; version.&lt;/p&gt;
2210
2211 &lt;p&gt;&lt;strong&gt;Who are you, and how do you spend your days?&lt;/strong&gt;&lt;/p&gt;
2212
2213 &lt;p&gt;My name is Mike Gabriel, I am 38 years old and live near Kiel,
2214 Schleswig-Holstein, Germany. I live together with a wonderful partner
2215 (Angela Fuß) and two own children and two bonus children (contributed
2216 by Angela).&lt;/p&gt;
2217
2218 &lt;p&gt;During the day I am part-time employed as a system administrator
2219 and part-time working as an IT consultant. The consultancy work
2220 touches free software topics wherever and whenever possible. During
2221 the nights I am a free software developer. In the gaps I also train in
2222 becoming an osteopath.&lt;/p&gt;
2223
2224 &lt;p&gt;Starting in 2010 we (Andreas Buchholz, Angela Fuß, Mike Gabriel)
2225 have set up a free software project in the area of Kiel that aims at
2226 introducing free software into schools. The project&#39;s name is
2227 &quot;IT-Zukunft Schule&quot; (IT future for schools). The project links IT
2228 skills with communication skills.&lt;/p&gt;
2229
2230 &lt;p&gt;&lt;strong&gt;How did you get in contact with the Skolelinux/Debian Edu
2231 project?&lt;/strong&gt;&lt;/p&gt;
2232
2233 &lt;p&gt;While preparing our own customised Linux distribution for
2234 &quot;IT-Zukunft Schule&quot; we were repeatedly asked if we really wanted to
2235 reinvent the wheel. What schools really need is already available,
2236 people said. From this impulse we started evaluating other Linux
2237 distributions that target being used for school networks.&lt;/p&gt;
2238
2239 &lt;p&gt;At the end we short-listed two approaches and compared them: a
2240 commercial Linux distribution developed by a company in Bremen,
2241 Germany, and Skolelinux / Debian Edu. Between 12/2010 and 03/2011 we
2242 went to several events and met people being responsible for marketing
2243 and development of either of the distributions. Skolelinux / Debian
2244 Edu was by far much more convincing compared to the other product that
2245 got short-listed beforehand--across the full spectrum. What was most
2246 attractive for me personally: the perspective of collaboration within
2247 the developmental branch of the Debian Edu project itself.&lt;/p&gt;
2248
2249 &lt;p&gt;In parallel with this, we talked to many local and not-so-local
2250 people. People teaching at schools, headmasters, politicians, data
2251 protection experts, other IT professionals.&lt;/p&gt;
2252
2253 &lt;p&gt;We came to two conclusions:&lt;/p&gt;
2254
2255 &lt;p&gt;First, a technical conclusion: What schools need is available in
2256 bits and pieces here and there, and none of the solutions really fit
2257 by 100%. Any school we have seen has a very individual IT setup
2258 whereas most of each school&#39;s requirements could mapped by a standard
2259 IT solution. The requirement to this IT solution is flexibility and
2260 customisability, so that individual adaptations here and there are
2261 possible. In terms of re-distributing and rolling out such a
2262 standardised IT system for schools (a system that is still to some
2263 degree customisable) there is still a lot of work to do here
2264 locally. Debian Edu / Skolelinux has been our choice as the starting
2265 point.&lt;/p&gt;
2266
2267 &lt;p&gt;Second, a holistic conclusion: What schools need does not exist at
2268 all (or we missed it so far). There are several technical solutions
2269 for handling IT at schools that tend to make a good impression. What
2270 has been missing completely here in Germany, though, is the enrolment
2271 of people into using IT and teaching with IT. &quot;IT-Zukunft Schule&quot;
2272 tries to provide an approach for this.&lt;/p&gt;
2273
2274 &lt;p&gt;Only some schools have some sort of a media concept which explains,
2275 defines and gives guidance on how to use IT in class. Most schools in
2276 Northern Germany do not have an IT service provider, the school&#39;s IT
2277 equipment is managed by one or (if the school is lucky) two (admin)
2278 teachers, most of the workload these admin teachers get done in there
2279 spare time.&lt;/p&gt;
2280
2281 &lt;p&gt;We were surprised that only a very few admin teachers were
2282 networked with colleagues from other schools. Basically, every school
2283 here around has its individual approach of providing IT equipment to
2284 teachers and students and the exchange of ideas has been quasi
2285 non-existent until 2010/2011.&lt;/p&gt;
2286
2287 &lt;p&gt;Quite some (non-admin) teachers try to avoid using IT technology in
2288 class as a learning medium completely. Several reasons for this
2289 avoidance do exist.&lt;/p&gt;
2290
2291 &lt;p&gt;We discovered that no-one has ever taken a closer look at this
2292 social part of IT management in schools, so far. On our quest journey
2293 for a technical IT solution for schools, we discussed this issue with
2294 several teachers, headmasters, politicians, other IT professionals and
2295 they all confirmed: a holistic approach of considering IT management
2296 at schools, an approach that includes the people in place, will be new
2297 and probably a gain for all.&lt;/p&gt;
2298
2299 &lt;p&gt;&lt;strong&gt;What do you see as the advantages of Skolelinux/Debian
2300 Edu?&lt;/strong&gt;&lt;/p&gt;
2301
2302 &lt;p&gt;There is a list of advantages: international context, openness to
2303 any kind of contributions, do-ocracy policy, the closeness to Debian,
2304 the different installation scenarios possible (from stand-alone
2305 workstation to complex multi-server sites), the transparency within
2306 project communication, honest communication within the group of
2307 developers, etc.&lt;/p&gt;
2308
2309 &lt;p&gt;&lt;strong&gt;What do you see as the disadvantages of Skolelinux/Debian
2310 Edu?&lt;/strong&gt;&lt;/p&gt;
2311
2312 &lt;p&gt;Every coin has two sides:&lt;/p&gt;
2313
2314 &lt;p&gt;Technically: &lt;a href=&quot;http://bugs.debian.org/311188&quot;&gt;BTS issue
2315 #311188&lt;/a&gt;, tricky upgradability of a Debian Edu main server, network
2316 client installations on top of a plain vanilla Debian installation
2317 should become possible sometime in the near future, one could think
2318 about splitting the very complex package debian-edu-config into
2319 several portions (to make it easier for new developers to
2320 contribute).&lt;/p&gt;
2321
2322 &lt;p&gt;Another issue I see is that we (as Debian Edu developers) should
2323 find out more about the network of people who do the marketing for
2324 Debian Edu / Skolelinux. There is a very active group in Germany
2325 promoting Skolelinux on the bigger Linux Days within Germany. Are
2326 there other groups like that in other countries? How can we bring
2327 these marketing people together (marketing group A with group B and
2328 all of them with the group of Debian Edu developers)? During the last
2329 meeting of the German Skolelinux group, I got the impression of people
2330 there being rather disconnected from the development department of
2331 Debian Edu / Skolelinux.&lt;/p&gt;
2332
2333 &lt;p&gt;&lt;strong&gt;Which free software do you use daily?&lt;/strong&gt;&lt;/p&gt;
2334
2335 &lt;p&gt;For my daily business, I do not use commercial software at all.&lt;/p&gt;
2336
2337 &lt;p&gt;For normal stuff I use Iceweasel/Firefox, Libreoffice.org. For
2338 serious text writing I prefer LaTeX. I use gimp, inkscape, scribus for
2339 more artistic tasks. I run virtual machines in KVM and Virtualbox.&lt;/p&gt;
2340
2341 &lt;p&gt;I am one of the upstream developers of X2Go. In 2010 I started the
2342 development of a Python based X2Go Client, called PyHoca-GUI.
2343 PyHoca-GUI has brought forth a Python X2Go Client API that currently
2344 is being integrated in Ubuntu&#39;s software center.&lt;/p&gt;
2345
2346 &lt;p&gt;For communications I have my own Kolab server running using Horde
2347 as web-based groupware client. For IRC I love to use irssi, for Jabber
2348 I have several clients that I use, mostly pidgin, though. I am also
2349 the Debian maintainer of Coccinella, a Jabber-based interactive
2350 whiteboard.&lt;/p&gt;
2351
2352 &lt;p&gt;My favourite terminal emulator is KDE&#39;s Yakuake.&lt;/p&gt;
2353
2354 &lt;p&gt;&lt;strong&gt;Which strategy do you believe is the right one to use to
2355 get schools to use free software?&lt;/strong&gt;&lt;/p&gt;
2356
2357 &lt;p&gt;Communicate, communicate, communicate. Enrol people, enrol people,
2358 enrol people.&lt;/p&gt;

2365 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Ralf_Gesellensetter.html</guid>
2366 <pubDate>Sun, 27 May 2012 17:15:00 +0200</pubDate>
2367 <description>&lt;p&gt;In 2003, a German teacher showed up on the
2368 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu and Skolelinux&lt;/a&gt;
2369 mailing list with interesting problems and reports proving he setting
2370 up Linux for a (for us at the time) lot of pupils. His name was Ralf
2371 Gesellensetter, and he has been an important tester and contributor
2372 since then, helping to make sure the
2373 &lt;a href=&quot;http://www.debian.org/News/2012/20120311.html&quot;&gt;Debian Edu
2374 Squeeze&lt;/a&gt; release became as good as it is..&lt;/p&gt;
2375
2376 &lt;p&gt;&lt;strong&gt;Who are you, and how do you spend your days?&lt;/strong&gt;&lt;/p&gt;
2377
2378 &lt;p&gt;I am a teacher from Germany, and my subjects are Geography,
2379 Mathematics, and Computer Science (&quot;Informatik&quot;). During the past 12
2380 years (since 2000), I have been working for a comprehensive (and soon,
2381 also inclusive) school leading to all kind of general levels, such as
2382 O- or A-level (&quot;Abitur&quot;). For quite as long, I&#39;ve been taking care of
2383 our computer network.&lt;/p&gt;
2384
2385 &lt;p&gt;Now, in my early 40s, I enjoy the privilege of spending a lot of my
2386 spare time together with my wife, our son (3 years) and our daughter
2387 (4 months).&lt;/p&gt;
2388
2389 &lt;p&gt;&lt;strong&gt;How did you get in contact with the Skolelinux/Debian Edu
2390 project?&lt;/strong&gt;&lt;/p&gt;
2391
2392 &lt;p&gt;We had tried different Linux based school servers, when members of
2393 my local Linux User Group (LUG OWL) detected Skolelinux. I remember
2394 very well, being part of a party celebrating the Linux New Media Award
2395 (&quot;Best Newcomer Distribution&quot;, also nominated: Ubuntu) that was given
2396 to Skolelinux at Linux World Exposition in Frankfurt, 2005 (IIRC). Few
2397 months later, I had the chance to join a developer meeting in Ulsrud
2398 (Oslo) and to hand out the award to Knut Yrvin and others. For more
2399 than 7 years, Skolelinux is part of our schools infrastructure, namely
2400 our main server (tjener), one LTSP (today without thin clients), and
2401 approximately 50 work stations. Most of these have the option to boot a
2402 locally installed Skolelinux image. As a consequence, I joined quite
2403 a few events dealing with free software or Linux, and met many Debian
2404 (Edu) developers. All of them seemed quite nice and competent to me,
2405 one more reason to stick to Skolelinux.&lt;/p&gt;
2406
2407 &lt;p&gt;&lt;strong&gt;What do you see as the advantages of Skolelinux/Debian
2408 Edu?&lt;/strong&gt;&lt;/p&gt;
2409
2410 &lt;p&gt;Debian driven, you are given all the advantages of a community
2411 project including well maintained updates. Once, you are familiar with
2412 the network layout, you can easily roll out an entire educational
2413 computer infrastructure, from just one installation media. As only
2414 free software (FOSS) is used, that supports even elderly hardware,
2415 up-sizing your IT equipment is only limited by space (i.e. available
2416 labs). Especially if you run a LTSP thin client server, your
2417 administration costs tend towards zero.&lt;/p&gt;
2418
2419 &lt;p&gt;&lt;strong&gt;What do you see as the disadvantages of Skolelinux/Debian
2420 Edu?&lt;/strong&gt;&lt;/p&gt;
2421
2422 &lt;p&gt;While Debian&#39;s stability has loads of advantages for servers, this
2423 might be different in some cases for clients: Schools with unlimited
2424 budget might buy new hardware with components that are not yet
2425 supported by Debian stable, or wish to use more recent versions of
2426 office packages or desktop environments. These schools have the
2427 option to run Debian testing or other distributions - if they have the
2428 capacity to do so. Another issue is that Debian release cycles
2429 include a wide range of changes; therefor a high percentage of human
2430 power seems to be absorbed by just keeping the features of Skolelinux
2431 within the new setting of the version to come. During this process,
2432 the cogs of Debian Edu are getting more and more professional,
2433 i.e. harder to understand for novices.&lt;/p&gt;
2434
2435 &lt;p&gt;&lt;strong&gt;Which free software do you use daily?&lt;/strong&gt;&lt;/p&gt;
2436
2437 &lt;p&gt;LibreOffice, Wikipedia, Openstreetmap, Iceweasel (Mozilla Firefox),
2438 KMail, Gimp, Inkscape - and of course the Linux Kernel (not only on
2439 PC, Laptop, Mobile, but also our SAT receiver)&lt;/p&gt;
2440
2441 &lt;p&gt;&lt;strong&gt;Which strategy do you believe is the right one to use to
2442 get schools to use free software?&lt;/strong&gt;&lt;/p&gt;
2443
2444 &lt;p&gt;&lt;ol&gt;
2445
2446 &lt;li&gt;Support computer science as regular subject in schools to make
2447 people really &quot;own&quot; their hardware, to make them understand the
2448 difference between proprietary software products, and free software
2449 developing.&lt;/li&gt;
2450
2451 &lt;li&gt;Make budget baskets corresponding: In Germany&#39;s public schools
2452 there are more or less fixed budgets for IT equipment (including
2453 licenses), so schools won&#39;t benefit from any savings here. This
2454 privilege is left to private schools which have consequently a large
2455 share among German Skolelinux schools.&lt;/li&gt;
2456
2457 &lt;li&gt;Get free software in the seminars where would-be teachers are
2458 trained. In many cases, teachers&#39; software customs are respected by
2459 decision makers rather than the expertise of any IT experts.&lt;/li&gt;
2460
2461 &lt;li&gt;Don&#39;t limit ourself to free software run natively. Everybody uses
2462 free software or free licenses (for instance Wikipedia), and this
2463 general concept should get expanded to free educational content to be
2464 shared world wide (school books e.g.).&lt;/li&gt;
2465
2466 &lt;li&gt;Make clear where ever you can that the market share of free (libre)
2467 office suites is much above 20 p.c. today, and that you pupils don&#39;t
2468 need to know the &quot;ribbon menu&quot; in order to get employed.&lt;/li&gt;
2469
2470 &lt;li&gt;Talk about the difference between freeware and free software.&lt;/li&gt;
2471
2472 &lt;li&gt;Spread free software, or even collections of portable free apps
2473 for USB pen drives. Endorse students to get a legal copy of
2474 Libreoffice rather than accepting them to use illegal serials. And
2475 keep sending documents in ODF formats.&lt;/li&gt;
2476
2477 &lt;/ol&gt;&lt;/p&gt;

2493 Tonny siden vi møttes som barn på påskefjellet i Ofoten, og ble
2494 gledelig overrasket da han dukket opp i Skolelinux-prosjektet etter å
2495 ikke ha sett noe til ham på mange år.&lt;/p&gt;
2496
2497 &lt;p&gt;&lt;strong&gt;Hvem er du, og hva driver du med til daglig?&lt;/strong&gt;&lt;/p&gt;
2498
2499 &lt;p&gt;Jeg er utdannet kokk av yrke, og har utøvet yrket i 12 år. Men
2500 etter at ryggen sa takk før seg, studerte jeg nettverksadministrasjon
2501 ved Næringsakademiet i Bergen årene 2008-2009 slik at jeg kunne
2502 forfølge en av mine største interesser - data. Til daglig jobber jeg
2503 ved &lt;a href=&quot;http://www.narvikskolen.no/parken/&quot;&gt;Parken
2504 ungdomsskole&lt;/a&gt; med å drifte skolens PC-er. Har også litt
2505 musikkundervisning.&lt;/p&gt;
2506
2507 &lt;p&gt;Mitt mål er å bevisstgjøre musikklærene mulighetene med de frie
2508 programmene som finnes i Skolelinux, blant annet Rosegarden.&lt;/p&gt;
2509
2510 &lt;p&gt;Har i mange år drevet med musikk og en av grunnen til at Rosegarden
2511 falt i smak for min del, var fordi denne fungere og ligner mest på
2512 Windows-programmet (cubase) jeg jobbet mye med da jeg i mine yngre
2513 dager var «Windows fanatiker». Ble introdusert til Linux av en kompis
2514 av meg for omtrent 14 år siden, og har bare blitt mer og mer glad i
2515 dette operativsystemet.&lt;/p&gt;
2516
2517 &lt;p&gt;&lt;strong&gt;Hvordan kom du i kontakt med Skolelinux-prosjektet?&lt;/strong&gt;&lt;/p&gt;
2518
2519 &lt;p&gt;Da jeg ble sykemeldt fra min gamle jobb, og måtte omskoleres,
2520 havnet jeg i 2007 sammen med Viggo Fedreheim på IKT-avdelingen i
2521 Narvik kommune, der ble jeg for første gang introdusert til
2522 Skolelinuxprosjektet.&lt;/p&gt;
2523
2524 &lt;p&gt;&lt;strong&gt;Hva er fordelene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
2525
2526 &lt;p&gt;Skolelinux er enkelt å holde i drift og masse flotte programmer som
2527 geogebra, ktouch og kgeografi følger med pakken. Man kan ta i bruk
2528 gamle PC-er igjen, slik at skoler med dårlig råd får opp en brukbar
2529 PC-park. PC-er som er ca 6-9 år gamle fungere tilfredstillende, bare
2530 de har 512 MB RAM eller mer.&lt;/p&gt;
2531
2532 &lt;p&gt;&lt;strong&gt;Hva er ulempene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
2533
2534 &lt;p&gt;Ulempene er at noen av de pedagogiske programmene som lærene ønsker
2535 å bruke fungere dårlig med Linux. Mye pga. av at disse programmene
2536 blir ikke laget til Linuxbaserte operativsystemer.&lt;/p&gt;
2537
2538 &lt;p&gt;Video- og bilde-redigering har dessverre en del mangler, mange av
2539 programmene har en tendens til og krasje. Det gjelder blant annet
2540 &lt;a href=&quot;http://www.kdenlive.org/&quot;&gt;kdenlive&lt;/a&gt; og
2541 &lt;a href=&quot;http://www.openshotvideo.com/&quot;&gt;openshot&lt;/a&gt;, for å nevne
2542 noen. De er ikke stabile nok. Når elevene kommer med filmsnutter de
2543 ønsker og jobbe med, så godtar ikke programmene filene, og når elevene
2544 jobber med redigering bare krasjer programmene uten forvarsel. Det er
2545 for vanskelig å få noe som bare fungerer ut av boksen her. Når en elev
2546 plugger inn et videokamera eller fotoapparat så er det alltid noe som
2547 ikke vil fungere. Programmene godtar ikke format, godtar ikke
2548 kameraet, osv., osv. Det er dessverre med på og dra ned en positiv
2549 opplevelse av bruk av fri programvare.&lt;/p&gt;
2550
2551 &lt;p&gt;Man må ofte bruke flere en et video redigerings program før og få
2552 fullført en ønsket oppgave.&lt;/p&gt;
2553
2554 &lt;p&gt;Eksempel:&lt;/p&gt;
2555
2556 &lt;p&gt;Hvis det ene programmet ikke vil ta i mot videofilen klarer et
2557 annet det, men det programmet som klarer det kan ikke gjøre de samme
2558 oppgavene som det programmet som ikke ville ta i mot filen,
2559 Tilsvarende er det med foto, man må bruke flere programmer for å få
2560 et ferdig resultat. Til dags dato har jeg enda ikke funnet et video-
2561 og fotoprogram som kan tilfredstillende fullføre en oppgave.&lt;/p&gt;
2562
2563 &lt;p&gt;Så man kan klare og fullføre en oppgave, men i verste fall må man
2564 innom 3-4 programmer for å få det til. Så jeg har enda ikke til dags
2565 dato sett at et program fungere 100% til alt.&lt;/p&gt;
2566
2567 &lt;p&gt;Det programmet jeg har best erfaring til er
2568 &lt;a href=&quot;http://cinelerra.org/&quot;&gt;cinelerra&lt;/a&gt;, men dessverre har det
2569 også tendenser og krasje av og til uten grunn.&lt;/p&gt;
2570
2571 Lydsystemet kan også være et mareritt. Konkret snakker jeg om når du
2572 bruker for eksempel et smartboard, så følger det med USB-lydkort på
2573 disse. Problemet ligger her i at systemet ikke vil velge rett
2574 lydkort, så man må inn med padevchooser for å sette opp PulseAudio
2575 til og velge at USB-lydkortet skal brukes. Det blir for tungvindt for
2576 lærene, de ønsker at ting skal fungere med en gang. (min løsning på
2577 det problemet ble at jeg måtte deaktivere lydkortet som fantes på
2578 maskinen) men da må man bestandig slå på smartboard-tavla.
2579
2580 &lt;p&gt;&lt;strong&gt;Hvilken fri programvare bruker du til daglig?&lt;/strong&gt;&lt;/p&gt;
2581
2582 Programmene jeg bruker mest av er: Rosegarden, jack, qsynth, audacity,
2583 k3b, openttd og libreoffice.
2584
2585 &lt;p&gt;&lt;strong&gt;Hvilken strategi tror du er den rette å bruke for å få
2586 skoler til å ta i bruk fri programvare?&lt;/strong&gt;&lt;/p&gt;
2587
2588 Jeg tror det må bevisstgjøring av Skolene til, dvs. reklamere høylytt
2589 og fortelle og vise de andre skolene at frie programvarer faktisk
2590 fungere. Jeg trur faktisk mange ikke vet at det finnes frie
2591 alternativer.

2596 <title>Debian Edu interview: Jürgen Leibner</title>
2597 <link>http://people.skolelinux.org/pere/blog/Debian_Edu_interview__J_rgen_Leibner.html</link>
2598 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Debian_Edu_interview__J_rgen_Leibner.html</guid>
2599 <pubDate>Sun, 13 May 2012 20:30:00 +0200</pubDate>
2600 <description>&lt;p&gt;It has been a few busy weeks for me, but I am finally back to
2601 publish another interview with the people behind
2602 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu and Skolelinux&lt;/a&gt;.
2603 This time it is one of our German developers, who have helped out over the
2604 years to make sure both a lot of major but also a lot of the minor
2605 details get right before release.
2606
2607 &lt;p&gt;&lt;strong&gt;Who are you, and how do you spend your days?&lt;/strong&gt;&lt;/p&gt;
2608
2609 &lt;p&gt;My name is Jürgen Leibner, I&#39;m 49 years old and living in
2610 Bielefeld, a town in northern Germany. I worked nearly 20 years as
2611 certified engineer in the department for plant design and layout of an
2612 international company for machinery and equipment. Since 2011 I&#39;m a
2613 certified technical writer (tekom e.V.) and doing technical
2614 documentations for a steam turbine manufacturer. From April this year
2615 I will manage the department of technical documentation at a
2616 manufacturer of automation and assembly line engineering.&lt;/p&gt;
2617
2618 &lt;p&gt;My first contact with linux was around 1993. Since that time I used
2619 it at work and at home repeatedly but not exclusively as I do now at
2620 home since 2006.&lt;/p&gt;
2621
2622 &lt;p&gt;&lt;strong&gt;How did you get in contact with the Skolelinux/Debian Edu
2623 project?&lt;/strong&gt;&lt;/p&gt;
2624
2625 &lt;p&gt;Once a day in the early year of 2001 when I wanted to fetch my
2626 daughter from primary school, there was a teacher sitting in the
2627 middle of 20 old computers trying to boot them and he failed. I helped
2628 him to get them booting. That was seen by the school director and she
2629 asked me if I would like to manage that the school gets all that old
2630 computers in use. I answered: &quot;Yes&quot;.&lt;/p&gt;
2631
2632 &lt;p&gt;Some weeks later every of the 10 classrooms had one computer
2633 running Windows98. I began to collect old computers and equipment as
2634 gifts and installed the first computer room with a peer-to-peer
2635 network. I did my work at school without being payed in my spare time
2636 and with a lot of fun. About one year later the school was connected
2637 to Internet and a local area network was installed in the school
2638 building. That was the time to have a server and I knew it must be a
2639 Linux server to be able to fulfil all the wishes of the teachers and
2640 being able to do this in a transparent and economic way, without extra
2641 costs for things like licence and software. So I searched for a
2642 school server system running under Linux and I found a couple of
2643 people nearby who founded &#39;skolelinux.de&#39;. It was the Skolelinux
2644 prerelease 32 I first tried out for being used at the school. I
2645 managed the IT of that school until the municipal authority took over
2646 the IT management and centralised the services for all schools in
2647 Bielefeld in December of 2006.&lt;/p&gt;
2648
2649 &lt;p&gt;&lt;strong&gt;What do you see as the advantages of Skolelinux/Debian
2650 Edu?&lt;/strong&gt;&lt;/p&gt;
2651
2652 &lt;p&gt;When I&#39;m looking back to the beginning, there were other advantages
2653 for me as today.&lt;/p&gt;
2654
2655 &lt;p&gt;In the past there were advantages like:&lt;/p&gt;
2656
2657 &lt;p&gt;&lt;ul&gt;
2658
2659 &lt;li&gt;I don&#39;t need to buy it so it generates no costs to the school as
2660 they had little money to spent for computers and software.&lt;/li&gt;
2661
2662 &lt;li&gt;It has a licence which grands all rights to use it without
2663 cost.&lt;/li&gt;
2664
2665 &lt;li&gt;It was more able to fit all requirements of a server system for
2666 schools than a Microsoft server system, even if there are only Windows
2667 clients because of it&#39;s preconfigured overall concept of being a
2668 infrastructure solution and community for schools, not only a
2669 server&lt;/li&gt;
2670
2671 &lt;li&gt;I was able to configure the server to the needs of the
2672 school.&lt;/li&gt;
2673
2674 &lt;/ul&gt;&lt;/p&gt;
2675
2676 &lt;p&gt;Today some of the advantages has been lost, changed or new ones
2677 came up in this way:&lt;/p&gt;
2678
2679 &lt;p&gt;&lt;ul&gt;
2680
2681 &lt;li&gt;Most schools here do have money to buy hardware and software
2682 now.&lt;/li&gt;
2683
2684 &lt;li&gt;They are today mostly managed from central IT departments which
2685 have own concepts which often do not fit to Debian Edu concepts
2686 because they are to close to Microsoft ideology.&lt;/li&gt;
2687
2688 &lt;li&gt;With the Squeeze version of Debian Edu which now uses GOsa² for
2689 management I feel more able to manage the daily tasks than with the
2690 interfaces used in the past.&lt;/li&gt;
2691
2692 &lt;li&gt;It is more modular than in the past and fits even better to the
2693 different needs.&lt;/li&gt;
2694
2695 &lt;li&gt;The documentation is usable and gets better every day.&lt;/li&gt;
2696
2697 &lt;li&gt;More people than ever before are using Debian Edu all over the
2698 world and so the community, which is an very important part I think,
2699 is sharing knowledge and minds.&lt;/li&gt;
2700
2701 &lt;li&gt;Most, maybe all, of the technical requirements for schools are
2702 solved today by Debian Edu. &lt;/li&gt;
2703
2704 &lt;/ul&gt;&lt;/p&gt;
2705
2706 &lt;p&gt;&lt;strong&gt;What do you see as the disadvantages of Skolelinux/Debian
2707 Edu?&lt;/strong&gt;&lt;/p&gt;
2708
2709 &lt;p&gt;&lt;ul&gt;
2710
2711 &lt;li&gt;There are too few IT companies able to integrate Debian Edu into
2712 their product portfolio for serving schools with concepts or even
2713 whole municipality areas.&lt;/li&gt;
2714
2715 &lt;li&gt;Debian Edu has beside other free and open software projects not
2716 enough lobbyists which promote free and open software to
2717 politicians.&lt;/li&gt;
2718
2719 &lt;li&gt;Technically there are no disadvantages I&#39;m aware of.&lt;/li&gt;
2720
2721 &lt;/ul&gt;&lt;/p&gt;
2722
2723 &lt;p&gt;&lt;strong&gt;Which free software do you use daily?&lt;/strong&gt;&lt;/p&gt;
2724
2725 &lt;p&gt;I use Debian stable on my home server and on my little desktop
2726 computer. On my laptop I use Debian testing/sid. The applications I
2727 use on my laptop and my desktop are Open/Libre-office, Iceweasel,
2728 KMail, DigiKam, Amarok, Dolphin, okular and all the other programs I
2729 need from the KDE environment. On console I use newsbeuter, mutt,
2730 screen, irssi and all the other famous and useful tools.&lt;/p&gt;
2731
2732 &lt;p&gt;My home server provides mail services with exim, dovecot, roundcube
2733 and mutt over ssh on the console, file services with samba, NFS,
2734 rsync, web services with apache, moinmoin-wiki, multimedia services
2735 with gallery2 and mediatomb and database services with MySQL for me
2736 and the whole family. I probably forgot something.&lt;/p&gt;
2737
2738 &lt;p&gt;&lt;strong&gt;Which strategy do you believe is the right one to use to
2739 get schools to use free software?&lt;/strong&gt;&lt;/p&gt;
2740
2741 &lt;p&gt;I believe, we should provide concepts for IT companies to integrate
2742 Debian Edu into their product portfolio with use cases for different
2743 countries and areas all over the world.&lt;/p&gt;

2748 <title>Forskning: &quot;GPL gir lokal frihet og kontroll gjennom omfordeling av makt fra produsent til bruker&quot;</title>
2749 <link>http://people.skolelinux.org/pere/blog/Forskning___GPL_gir_lokal_frihet_og_kontroll_gjennom_omfordeling_av_makt_fra_produsent_til_bruker_.html</link>

2751 <pubDate>Sun, 15 Apr 2012 13:00:00 +0200</pubDate>
2752 <description>&lt;p&gt;Da jeg googlet etter noe annet kom jeg tilfeldigvis over
2753 &lt;a href=&quot;http://www.duo.uio.no/sok/work.html?WORKID=58309&quot;&gt;en
2754 hovedfagsoppgave&lt;/a&gt; ved Universitetet i Oslo som diskuterer verdien
2755 av GPLs fire friheter for brukerne av IT-systemer. Jeg ble fascinert
2756 over det som presenteres der. Her er sammendraget:&lt;/p&gt;
2757
2758 &lt;p&gt;&lt;blockquote&gt;
2759
2760 &lt;p&gt;Motivasjonen til å skrive denne oppgaven er en personlig undring
2761 over hvorfor det primært, og ofte eksklusivt, fokuseres på det
2762 økonomiske aspektet ved utredninger om fri programvare er et godt valg
2763 for det offentlige. Fri og produsenteid programvare bygger på
2764 fundamentalt forskjellige ideologier som kan ha implikasjoner utover
2765 økonomiske kostnader. Kunnskapskulturen som er med på å definere fri
2766 programvare er basert på åpenhet, og er en verdi i seg selv.&lt;/p&gt;
2767
2768 &lt;p&gt;Oppgavens tema er programvarelisensen GPL og frihet. GPL-lisensiert
2769 programvare gir visse friheter i forhold til produsenteid
2770 programvare. Mitt spørsmål er om, og eventuelt i hvilken utstrekning,
2771 disse frihetene blir benyttet av ulike brukere og hvordan de
2772 manifesterer seg for disse brukerne. Sentrale spørsmål i oppgaven
2773 er:&lt;/p&gt;
2774
2775 &lt;ul&gt;
2776 &lt;li&gt;Hvordan fordeles handlekraft gjennom lisensieringen av programvaren?&lt;/li&gt;
2777 &lt;li&gt;Hvilke konsekvenser har programvarelisensen for de ulike brukere? &lt;/li&gt;
2778 &lt;/ul&gt;
2779
2780 &lt;p&gt;Fri programvare gir blant annet brukeren mulighet til å studere og
2781 modifisere kildekoden. Denne formen for frihet erverves gjennom
2782 kunnskap og krever at brukeren også er en ekspert. Hva skjer med
2783 frihetene til GPL når sluttbrukeren er en annen? Dette diskuteres i
2784 dialog med informantene.&lt;/p&gt;
2785
2786 &lt;p&gt;Jeg har i denne oppgaven samlet inn intervjudata fra IKT-ansvarlige
2787 ved grunnskolene i Nittedal kommune, driftsansvarlig og IKT-veilederen
2788 for skolene i kommunen, samt IKT-koordinator for utdanning i Akershus
2789 fylkeskommune og bokmåloversettere av OpenOffice.org. Den empiriske
2790 delen av oppgaven er delt inn i to seksjoner; den første omhandler
2791 operativsystemet Skolelinux, den andre kontorprogrampakken
2792 OpenOffice.org.&lt;/p&gt;
2793
2794 &lt;p&gt;Som vi vil se gir GPL lokal frihet og kontroll gjennom omfordeling
2795 av makt fra produsent til bruker. Brukerens makt analyseres gjennom
2796 begrepene brukermedvirkning og handlingsfrihet. Det blir også lagt
2797 vekt på strukturelle forhold rundt bruken av teknologi, og spesielt de
2798 økonomiske begrepene nettverkseksternaliteter, innlåsing og
2799 stiavhengighet. Dette er begreper av spesiell nytte når objektet som
2800 omsettes eller distribueres er et kommunikasjonsprodukt, fordi verdien
2801 til et slikt gode for en potensiell bruker avhenger av antall
2802 eksisterende brukere av godet. I tilknytning til denne problematikken
2803 inneholder oppgaven også en diskusjon rundt åpne standarder og
2804 formater.&lt;/p&gt;
2805
2806 &lt;p&gt;Oppgaven konkluderer med at de «fire frihetene» som GPL-lisensen er
2807 laget for å beskytte er av avgjørende betydning for bruken av
2808 OpenOffice.org og Skolelinux, i Akershus fylkeskommune såvel som i
2809 skolene i Nittedal. Distribusjonen av handlekraft er ikke helt
2810 symmetrisk. Det er først og fremst de profesjonelle utviklerne i
2811 Skolelinux som direkte kan nyttiggjøre seg friheten til å endre kode,
2812 mens en sluttbruker som Nittedal kommune nyttiggjør seg den økonomiske
2813 friheten til å kunne distribuere programmene. Det er imidlertid også
2814 slik at ingen aktør klarer seg uten alle disse «frihetene».&lt;/p&gt;
2815 &lt;/blockquote&gt;&lt;/p&gt;
2816
2817 &lt;p&gt;Jeg fant også en masteroppgave fra 2006, men der ligger ikke
2818 komplett oppgave tilgjengelig. På tide å holde et øye med
2819 &lt;a href=&quot;http://www.duo.uio.no/sok/search.html?q=skolelinux&quot;&gt;Skolelinux-søket&lt;/a&gt;
2820 til DUO...&lt;/p&gt;

2826 <title>Debian Edu interview: Andreas Mundt</title>
2827 <link>http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Andreas_Mundt.html</link>
2828 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Andreas_Mundt.html</guid>
2829 <pubDate>Sun, 15 Apr 2012 12:10:00 +0200</pubDate>
2830 <description>&lt;p&gt;Behind &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu and
2831 Skolelinux&lt;/a&gt; there are a lot of people doing the hard work of
2832 setting together all the pieces. This time I present to you Andreas
2833 Mundt, who have been part of the technical development team several
2834 years. He was also a key contributor in getting GOsa and Kerberos set
2835 up in the recently released
2836 &lt;a href=&quot;http://wiki.debian.org/DebianEdu/Documentation/Squeeze&quot;&gt;Debian
2837 Edu Squeeze&lt;/a&gt; version.&lt;/p&gt;
2838
2839 &lt;p&gt;&lt;strong&gt;Who are you, and how do you spend your days?&lt;/strong&gt;&lt;/p&gt;
2840
2841 &lt;p&gt;My name is Andreas Mundt, I grew up in south Germany. After
2842 studying Physics I spent several years at university doing research in
2843 Quantum Optics. After that I worked some years in an optics company.
2844 Finally I decided to turn over a new leaf in my life and started
2845 teaching 10 to 19 years old kids at school. I teach math, physics,
2846 information technology and science/technology.&lt;/p&gt;
2847
2848 &lt;p&gt;&lt;strong&gt;How did you get in contact with the Skolelinux/Debian Edu
2849 project?&lt;/strong&gt;&lt;/p&gt;
2850
2851 &lt;p&gt;Already before I switched to teaching, I followed the Debian Edu
2852 project because of my interest in education and Debian. Within the
2853 qualification/training period for the teaching, I started
2854 contributing.&lt;/p&gt;
2855
2856 &lt;p&gt;&lt;strong&gt;What do you see as the advantages of Skolelinux/Debian
2857 Edu?&lt;/strong&gt;&lt;/p&gt;
2858
2859 &lt;p&gt;The advantages of Debian Edu are the well known name, the
2860 out-of-the-box philosophy and of course the great free software of the
2861 Debian Project!&lt;/p&gt;
2862
2863 &lt;p&gt;&lt;strong&gt;What do you see as the disadvantages of Skolelinux/Debian
2864 Edu?&lt;/strong&gt;&lt;/p&gt;
2865
2866 &lt;p&gt;As every coin has two sides, the out-of-the-box philosophy has its
2867 downside, too. In my opinion, it is hard to modify and tweak the
2868 setup, if you need or want that. Further more, it is not easily
2869 possible to upgrade the system to a new release. It takes much too
2870 long after a Debian release to prepare the -Edu release, perhaps
2871 because the number of developers working on the core of the code is
2872 rather small and often busy elsewhere.&lt;/p&gt;
2873
2874 &lt;p&gt;The &lt;a href=&quot;http://wiki.debian.org/DebianLAN&quot;&gt;Debian LAN&lt;/a&gt;
2875 project might fill the use case of a more flexible system.&lt;/p&gt;
2876
2877 &lt;p&gt;&lt;strong&gt;Which free software do you use daily?&lt;/strong&gt;&lt;/p&gt;
2878
2879 &lt;p&gt;I am only using non-free software if I am forced to and run Debian
2880 on all my machines. For documents I prefer LaTeX and PGF/TikZ, then
2881 mutt and iceweasel for email respectively web browsing. At school I
2882 have Arduino and Fritzing in use for a micro controller project.&lt;/p&gt;
2883
2884 &lt;p&gt;&lt;strong&gt;Which strategy do you believe is the right one to use to
2885 get schools to use free software?&lt;/strong&gt;&lt;/p&gt;
2886
2887 &lt;p&gt;One of the major problems is the vendor lock-in from top to bottom:
2888 Especially in combination with ignorant government employees and
2889 politicians, this works out great for the &quot;market-leader&quot;. The school
2890 administration here in Baden-Wuerttemberg is occupied by that vendor.
2891 Documents have to be prepared in non-free, proprietary formats. Even
2892 free browsers do not work for the school administration. Publishers
2893 of school books provide software only for proprietary platforms.&lt;/p&gt;
2894
2895 &lt;p&gt;To change this, political work is very important. Parts of the
2896 political spectrum have become aware of the problem in the last years.
2897 However it takes quite some time and courageous politicians to &#39;free&#39;
2898 the system. There is currently some discussion about &quot;Open Data&quot; and
2899 &quot;Free/Open Standards&quot;. I am not sure if all the involved parties have
2900 a clue about the potential of these ideas, and probably only a
2901 fraction takes them seriously. However it might slowly make free
2902 software and the philosophy behind it more known and popular.&lt;/p&gt;

2907 <title>Debian Edu interview: Justin B. Rye</title>
2908 <link>http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Justin_B__Rye.html</link>
2909 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Justin_B__Rye.html</guid>
2910 <pubDate>Sun, 8 Apr 2012 10:50:00 +0200</pubDate>
2911 <description>&lt;p&gt;It take all kind of contributions to create a Linux distribution
2912 like &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu / Skolelinux&lt;/a&gt;,
2913 and this time I lend the ear to Justin B. Rye, who is listed as a big
2914 contributor to the
2915 &lt;a href=&quot;http://wiki.debian.org/DebianEdu/Documentation/Squeeze&quot;&gt;Debian
2916 Edu Squeeze release manual&lt;/a&gt;.
2917
2918 &lt;p&gt;&lt;strong&gt;Who are you, and how do you spend your days?&lt;/strong&gt;&lt;/p&gt;
2919
2920 &lt;p&gt;I&#39;m a 44-year-old linguistics graduate living in Edinburgh who has
2921 occasionally been employed as a sysadmin.&lt;/p&gt;
2922
2923 &lt;p&gt;&lt;strong&gt;How did you get in contact with the Skolelinux/Debian Edu
2924 project?&lt;/strong&gt;&lt;/p&gt;
2925
2926 &lt;p&gt;I&#39;m neither a developer nor a Skolelinux/Debian Edu user! The only
2927 reason my name&#39;s in the credits for the documentation is that I hang
2928 around on debian-l10n-english waiting for people to mention things
2929 they&#39;d like a native English speaker to proofread... So I did a sweep
2930 through the wiki for typos and Norglish and inconsistent spellings of
2931 &quot;localisation&quot;.&lt;/p&gt;
2932
2933 &lt;p&gt;&lt;strong&gt;What do you see as the advantages of Skolelinux/Debian
2934 Edu?&lt;/strong&gt;&lt;/p&gt;
2935
2936 &lt;p&gt;&lt;strong&gt;What do you see as the disadvantages of Skolelinux/Debian
2937 Edu?&lt;/strong&gt;&lt;/p&gt;
2938
2939 &lt;p&gt;These questions are too hard for me - I don&#39;t use it! In fact I
2940 had hardly any contact with I.T. until long after I&#39;d got out of the
2941 education system.&lt;/p&gt;
2942
2943 &lt;p&gt;I can tell you the advantages of Debian for me though: it soaks up
2944 as much of my free time as I want and no more, and lets me do
2945 everything I want a computer for without ever forcing me to spend
2946 money on the latest hardware.&lt;/p&gt;
2947
2948 &lt;p&gt;&lt;strong&gt;Which free software do you use daily?&lt;/strong&gt;&lt;/p&gt;
2949
2950 &lt;p&gt;I&#39;ve been using Debian since Rex; popularity-contest says the
2951 software that I use most is xinit, xterm, and xulrunner (in other
2952 words, I use a distinctly retro sort of desktop).&lt;/p&gt;
2953
2954 &lt;p&gt;&lt;strong&gt;Which strategy do you believe is the right one to use to
2955 get schools to use free software?&lt;/strong&gt;&lt;/p&gt;
2956
2957 &lt;p&gt;Well, I don&#39;t know. I suppose I&#39;d be inclined to try reasoning
2958 with the people who make the decisions, but obviously if that worked
2959 you would hardly need a strategy.&lt;/p&gt;

2964 <title>Why the KDE menu is slow when /usr/ is NFS mounted - and a workaround</title>

2966 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Why_the_KDE_menu_is_slow_when__usr__is_NFS_mounted___and_a_workaround.html</guid>
2967 <pubDate>Fri, 6 Apr 2012 22:40:00 +0200</pubDate>
2968 <description>&lt;p&gt;Recently I have spent time with
2969 &lt;a href=&quot;http://www.slxdrift.no/&quot;&gt;Skolelinux Drift AS&lt;/a&gt; on speeding
2970 up a &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu / Skolelinux&lt;/a&gt;
2971 Lenny installation using LTSP diskless workstations, and in the
2972 process I discovered something very surprising. The reason the KDE
2973 menu was responding slow when using it for the first time, was mostly
2974 due to the way KDE find application icons. I discovered that showing
2975 the Multimedia menu would cause more than 20 000 IP packages to be
2976 passed between the LTSP client and the NFS server. Most of these were
2977
2978 NFS LOOKUP calls, resulting in a NFS3ERR_NOENT response. Because the
2979 ping times between the client and the server were in the range 2-20
2980 ms, the menus would be very slow. Looking at the strace of kicker in
2981 Lenny (or plasma-desktop i Squeeze - same problem there), I see that
2982 the source of these NFS calls are access(2) system calls for
2983 non-existing files. KDE can do hundreds of access(2) calls to find
2984 one icon file. In my example, just finding the mplayer icon required
2985 around 230 access(2) calls.&lt;/p&gt;
2986
2987 &lt;p&gt;The KDE code seem to search for icons using a list of icon
2988 directories, and the list of possible directories is large. In
2989 (almost) each directory, it look for files ending in .png, .svgz, .svg
2990 and .xpm. The result is a very slow KDE menu when /usr/ is NFS
2991 mounted. Showing a single sub menu may result in thousands of NFS
2992 requests. I am not the first one to discover this. I found a
2993 &lt;a href=&quot;https://bugs.kde.org/show_bug.cgi?id=211416&quot;&gt;KDE bug report
2994 from 2009&lt;/a&gt; about this problem, and it is still unsolved.&lt;/p&gt;
2995
2996 &lt;p&gt;My solution to speed up the KDE menu was to create a package
2997 kde-icon-cache that upon installation will look at all .desktop files
2998 used to generate the KDE menu, find their icons, search the icon paths
2999 for the file that KDE will end up finding at run time, and copying the
3000 icon file to /var/lib/kde-icon-cache/. Finally, I add symlinks to
3001 these icon files in one of the first directories where KDE will look
3002 for them. This cut down the number of file accesses required to find
3003 one icon from several hundred to less than 5, and make the KDE menu
3004 almost instantaneous. I&#39;m not quite sure where to make the package
3005 publicly available, so for now it is only available on request.&lt;/p&gt;
3006
3007 &lt;p&gt;The bug report mention that this do not only affect the KDE menu
3008 and icon handling, but also the login process. Not quite sure how to
3009 speed up that part without replacing NFS with for example NBD, and
3010 that is not really an option at the moment.&lt;/p&gt;
3011
3012 &lt;p&gt;If you got feedback on this issue, please let us know on debian-edu
3013 (at) lists.debian.org.&lt;/p&gt;

3036 <pubDate>Sun, 1 Apr 2012 23:00:00 +0200</pubDate>
3037 <description>&lt;p&gt;Germany is a core area for the
3038 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu and Skolelinux&lt;/a&gt;
3039 user community, and this time I managed to get hold of Wolfgang
3040 Schweer, a valuable contributor to the project from Germany.
3041
3042 &lt;p&gt;&lt;strong&gt;Who are you, and how do you spend your days?&lt;/strong&gt;&lt;/p&gt;
3043
3044 &lt;p&gt;I&#39;ve studied Mathematics at the university &#39;Ruhr-Universität&#39; in
3045 Bochum, Germany. Since 1981 I&#39;m working as a teacher at the school
3046 &quot;&lt;a href=&quot;http://www.westfalenkolleg-dortmund.de/&quot;&gt;Westfalen-Kolleg
3047 Dortmund&lt;/a&gt;&quot;, a second chance school. Here, young adults is given
3048 the opportunity to get further education in order to do the school
3049 examination &#39;Abitur&#39;, which will allow to study at a university. This
3050 second chance is of value for those who want a better job perspective
3051 or failed to get a higher school examination being teens.&lt;/p&gt;
3052
3053 &lt;p&gt;Besides teaching I was involved in developing online courses for a
3054 blended learning project called &#39;abitur-online.nrw&#39; and in some other
3055 information technology related projects. For about ten years I&#39;ve been
3056 teacher and coordinator for the &#39;abitur-online&#39; project at my
3057 school. Being now in my early sixties, I&#39;ve decided to leave school at
3058 the end of April this year.&lt;/p&gt;
3059
3060 &lt;p&gt;&lt;strong&gt;How did you get in contact with the Skolelinux/Debian Edu
3061 project?&lt;/strong&gt;&lt;/p&gt;
3062
3063 &lt;p&gt;The first information about Skolelinux must have come to my
3064 attention years ago and somehow related to LTSP (Linux Terminal Server
3065 Project). At school, we had set up a network at the beginning of 1997
3066 using Suse Linux on the desktop, replacing a Novell network. Since
3067 2002, we used old machines from the city council of Dortmund as thin
3068 clients (LTSP, later Ubuntu/Lessdisks) cause new hardware was out of
3069 reach. At home I&#39;m using Debian since years and - subscribed to the
3070 Debian news letter - heard from time to time about Skolelinux. About
3071 two years ago I proposed to replace the (somehow undocumented and only
3072 known to me) system at school by a well known Debian based system:
3073 Skolelinux.&lt;/p&gt;
3074
3075 &lt;p&gt;Students and teachers appreciated the new system because of a
3076 better look and feel and an enhanced access to local media on thin
3077 clients. The possibility to alter and/or reset passwords using a GUI
3078 was welcomed, too. Being able to do administrative tasks using a GUI
3079 and to easily set up workstations using PXE was of very high value for
3080 the admin teachers.&lt;/p&gt;
3081
3082 &lt;p&gt;&lt;strong&gt;What do you see as the advantages of Skolelinux/Debian
3083 Edu?&lt;/strong&gt;&lt;/p&gt;
3084
3085 &lt;p&gt;It&#39;s open source, easy to set up, stable and flexible due to it&#39;s
3086 Debian base. It integrates LTSP out-of-the-box. And it is documented!
3087 So it was a perfect choice.&lt;/p&gt;
3088
3089 &lt;p&gt;Being open source, there are no license problems and so it&#39;s
3090 possible to point teachers and students to programs like
3091 OpenOffice.org, ViewYourMind (mind mapping) and The Gimp. It&#39;s of
3092 high value to be able to adapt parts of the system to special needs of
3093 a school and to choose where to get support for this.&lt;/p&gt;
3094
3095 &lt;p&gt;&lt;strong&gt;What do you see as the disadvantages of Skolelinux/Debian
3096 Edu?&lt;/strong&gt;&lt;/p&gt;
3097
3098 &lt;p&gt;Nothing yet.&lt;/p&gt;
3099
3100 &lt;p&gt;&lt;strong&gt;Which free software do you use daily?&lt;/strong&gt;&lt;/p&gt;
3101
3102 &lt;p&gt;At home (Debian Sid with Gnome Desktop): Iceweasel, LibreOffice,
3103 Mutt, Gedit, Document Viewer, Midnight Commander, flpsed (PDF
3104 Annotator). At school (Skolelinux Lenny): Iceweasel, Gedit,
3105 LibreOffice.&lt;/p&gt;
3106
3107 &lt;p&gt;&lt;strong&gt;Which strategy do you believe is the right one to use to
3108 get schools to use free software?&lt;/strong&gt;&lt;/p&gt;
3109
3110 &lt;p&gt;Some time ago I thought it was enough to tell people about it. But
3111 that doesn&#39;t seem to work quite well. Now I concentrate on those more
3112 interested and hope to get multiplicators that way.&lt;/p&gt;

3120 <pubDate>Fri, 30 Mar 2012 19:30:00 +0200</pubDate>
3121 <description>&lt;p&gt;I dag har &lt;a href=&quot;http://www.friprogramvareiskolen.no&quot;&gt;FRiSK&lt;/a&gt;
3122 sendt ut følgende pressemelding basert på mine beregninger av
3123 PC-tetthet på Linux-skoler:&lt;/p&gt;
3124
3125 &lt;p&gt;&lt;strong&gt;Linux-skoler har høyere PC-tetthet enn
3126 landsgjennomsnittet&lt;/strong&gt;&lt;/p&gt;
3127
3128 &lt;p&gt;Oslo, 30 Mars 2012&lt;/p&gt;
3129
3130 &lt;p&gt;Det er store forskjeller på skolenes digitale tilstand, viser
3131 undersøkelsen Monitor 2011 som er laget på oppdrag fra
3132 Kunnskapsdepartementet. Dette har ført til debatt om PC-tilgangen i
3133 skolen, og om de med Linux i skolen gjør det bedre bedre eller
3134 dårligere enn snittet i landet.&lt;/p&gt;
3135
3136 &lt;p&gt;Nå har vi tallene. Skoler med Linux har 36% større PC-tetthet en
3137 landsgjennomsnittet. På spørsmål hvorfor skoler med Linux har større
3138 PC-tetthet, observerer Paul Reidar Løsnesløkken som er IKT-konsulent i
3139 Nord-Odal:&lt;/p&gt;
3140
3141 &lt;p&gt;&lt;blockquote&gt;&quot;Vi erfarer at klienter med Skolelinux har god funksjon
3142 til de er 8 til 10 år gamle. Dette er omtrent dobbelt så lenge som
3143 andre løsninger, og skolene får mer datautstyr for
3144 pengene.&quot;&lt;/blockquote&gt;&lt;/p&gt;
3145
3146 &lt;p&gt;Undersøkelsen baserer seg på 56 skoler som har gjort det offentlig
3147 at de kjører Skolelinux eller annen Linux-utgave. De kan også ha PC-er
3148 med Windows i skolenettet. Når en sammenligner PC-tetthetene på
3149 skolene i kommunene Flora, Harstad, Kongsvinger, Narvik, Nittedal,
3150 Nord-Odal og Randaberg, er det i snitt 2,28 elev pr. PC på skolene med
3151 Linux. På landsbasis er det 3.11 elev per PC i grunnskolen, i følge
3152 side 95 i Monitor-rapporten for 2011. Målingen viser dermed 36% større
3153 PC-tetthet i skoler med Linux.&lt;/p&gt;
3154
3155 &lt;p&gt;&lt;strong&gt;Om Skolelinux/Debian Edu&lt;/strong&gt;&lt;/p&gt;
3156
3157 &lt;p&gt;Skolelinux har til hensikt å gi alle barn full tilgang til
3158 skoleaktuelle dataprogram på sitt eget morsmål. Derfor følger det med
3159 godt over 100 skoleaktuelle programmene laget for læring. De fleste
3160 programmene er oversatt til over 50 språk. Elevene skal også kunne
3161 studere alle sider av dataprogrammene. Derfor følger også kildekode
3162 med. Elever med interesse kan lære av eksperter som har laget
3163 systemet. Dette med enkelt programmering i læreprogram som KTurtle,
3164 til profesjonelle verktøy som Qt Creator eller Java.&lt;/p&gt;
3165
3166 &lt;p&gt;Skolelinux er laget for sentralisert drift, der alt teknisk
3167 administrasjon av alle skolene kan gjøres sentralt fra kommunehuset
3168 eller sentralt i en region. F.eks. drifter to-tre personer 70.000
3169 skoledatamaskiner på 200 skoler i delstaten Extremadura i
3170 Spania. Etter velykket bruk av Debian Edu i skolen, legger delstaten
3171 over til Debian på 40.000 datamaskiner i administrasjonen. Det er idag
3172 mange selskap som tilbyr profesjonell støtte til innføring og drift i
3173 Norge og verden.&lt;/p&gt;

3210 <description>&lt;p&gt;I serien med intervjuer av folk i
3211 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt;-miljøet, får vi
3212 denne gangen høre fra en IKT-ansvarlig som har brukt Skolelinux i
3213 mange år, og vært storfornøyd med erfaringene så langt.&lt;/p&gt;
3214
3215 &lt;p&gt;&lt;strong&gt;Hvem er du, og hva driver du med til daglig?&lt;/strong&gt;&lt;/p&gt;
3216
3217 &lt;p&gt;Mitt navn er Roy-Arne Myhre og jeg er 42 år. Jeg er ansatt hos
3218 &lt;a href=&quot;http://www.sandskole.no/&quot;&gt;Sand skole&lt;/a&gt; (Balsfjord kommune)
3219 og har stort sett vært det siden 1990. Jeg er IKT ansvarlig ved
3220 skolen i 40% stilling – 10% undervisning – musikk.&lt;/p&gt;
3221
3222 &lt;p&gt;Ved skolen er det ca 100 elever og ca 18 lærere + 4 assistenter i
3223 hele og delte stillinger. Alle lærerne har bærbar PC (dessverre med
3224 Win Vista) – assistenter har tilgang til egne. Vi benytter Fronter i
3225 det daglige arbeidet. Vi har ca 90 elevmaskiner som fungerer til
3226 daglig opp mot Linux server (XFCE) som driftes av
3227 &lt;a href=&quot;http://www.bzz.no/&quot;&gt;BzzWare AS&lt;/a&gt; via nett. Maskinparken
3228 består kun av brukt utstyr for elevene – og noe av dette begynner å
3229 bli vel gammelt selv som halvtykke klienter.&lt;/p&gt;
3230
3231 &lt;p&gt;&lt;strong&gt;Hvordan kom du i kontakt med
3232 Skolelinux-prosjektet?&lt;/strong&gt;&lt;/p&gt;
3233
3234 &lt;p&gt;Vi kom første gang i kontakt med Skolelinux rundt 1997. Den gang
3235 var det oppstart-disketter i hver maskin, ikke mulighet for lyd og
3236 video, gamle nettverkskort og mye plundring. Vi hadde en ihuga
3237 forelder med som pådriver, forsker og inspirator for hele opplegget.
3238 Selv ante jeg knapt at Skolelinux fantes, men han var av den
3239 utforskende typen, og fikk både meg og skolelederen i trua på at dette
3240 var ting som kunne fungere. Etter dette har det gått gradvis
3241 framover; flere maskiner er hentet inn gjennom bl.a
3242 &lt;a href=&quot;http://www.greentech.no/&quot;&gt;Greentech&lt;/a&gt; og utrangert utstyr
3243 fra høgskole / Avinor og private givere. Når maskinene ble for trege
3244 for nye Windows-versjoner, sto vi klare til å putte dem i nettverket
3245 vårt. Dette betyr at vi i dag har 1:1 dekning av maskiner på
3246 ungdomstrinnet og bedre enn 1:2 på barnetrinnet. Dette er vi veldig
3247 fornøyd med, og vi kan ikke se for oss hverdagen som ville vært
3248 alternativet ved bruk av Windows med sine lisenser pr. Bruker/maskin.
3249 Da ville vi nok vært tilbake til 1-2 maskiner pr klasserom med de
3250 negative konsekvenser det ville hatt for undervisningsformene våre. Vi
3251 kan ha en hel klasse i prosjektjobbing eller individuell jobbing
3252 samtidig – vi kan avholde tentamen og eksamen uten
3253 logistikkproblemer.&lt;/p&gt;
3254
3255 &lt;p&gt;&lt;strong&gt;Hva er fordelene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
3256
3257 Hvor skal jeg begynne... Stabiliteten er et nøkkelord - det bare
3258 virker. Har du først fått en server med Skolelinux opp og gå, så må
3259 det en maskinarefeil eller sabotasje til for å stoppe den. Det at man
3260 kan bruke eldre maskiner som normalt sett ville gått på dynga, er også
3261 glimrende - billig for skoler med dårlig økonomi og bra for miljøet
3262 siden vi gjenbruker utstyr i stedet for å skaffe nytt. Vi ville aldri
3263 hatt mulighet til å operere med det maskinantallet vi har pr i dag
3264 hvis det ikke var for Skolelinux - så tilgjengelighet er et annet
3265 nøkkelord. Et tredje moment er sikkerhet og brukertilgang. Alle
3266 brukerer opererer med egne brukernavn og passord, samt egne
3267 brukerområder som kan tilpasses for både enbrukertilgang og for
3268 samarbeid med andre.
3269
3270 Elever har godt av å se at det finnes andre alternativer enn de som
3271 storindustrien selger på lisensbasis - på den måten trenes de opp til
3272 å se flere muligheter og å foreta valg ut fra flere opsjoner.
3273
3274 &lt;p&gt;&lt;strong&gt;Hva er ulempene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
3275
3276 &lt;p&gt;Ulempene med Skolelinux er nok utbredelsen og mangelen på kjennskap
3277 til dette i skolenorge. De som skal ta økonomiske avgjørelser rynker
3278 på nesen og vil gå for det kjente og «sikre» selv om det koster mye
3279 mer. Man får rett og slett litt hetta av å ikke kunne noe – og unngår
3280 dette for enhver pris.&lt;/p&gt;
3281
3282 &lt;p&gt;I tillegg er mye av linux-systemet administrert av tekstkommandoer
3283 og er lite intuitiv/visuell for oss som ikke er «inne i»
3284 kildekodene». Så problemet er nok mye godt at de som
3285 utarbeider/drifter Skolelinux ikke helt klarer å sette seg ned på
3286 skoleadministratorens nivå når det gjelder problemer og
3287 utfordringer. Men dette er nok en utfordring alle administratorer
3288 sliter med uansett OS.&lt;/p&gt;
3289
3290 &lt;p&gt;Derfor har vi valgt å støtte oss til BzzWare AS for assistanse i
3291 drifta slik at jeg har kunnet konsentrere meg mer om kabling, skifting
3292 av komponenter, veiledning av lærere og elever, vedlikehold av
3293 skrivere og annen daglig drift.&lt;/p&gt;
3294
3295 &lt;p&gt;Elevene mestrer Skolelinux helt fint. Så lenge Internett
3296 (Iceweasel) og Libreoffice (Openoffice) fungerer er 90% av
3297 skolehverdagen velfungerende. I tillegg brukes jo en del av den
3298 pedagogiske programpakken bla. i forhold til matematikk og geografi,
3299 men det er såpass mye bra på nett om dagen, så disse programmene er
3300 mer som krydder å regne.&lt;/p&gt;
3301
3302 &lt;p&gt;Jeg skulle ønske neste versjon av Skolelinux kunne komme litt
3303 mindre stappet med programmer, for halvparten blir aldri brukt, eller
3304 fungerer ikke uansett. Hva med et pedagogisk panel av lærere/IKT
3305 ansvarlige som kunne sagt: disse programmene skal være standard, så
3306 får resten være slike man kan legge til ved behov – det kan lett bli
3307 en jungel å bevege seg i.&lt;/p&gt;
3308
3309 &lt;p&gt;Jeg ønsker meg også en mer grafisk versjon av
3310 &lt;a href=&quot;http://bzz.no/lwat/trac/trac.cgi&quot;&gt;Lwat&lt;/a&gt; hvor man kan krysse
3311 ut de som f.eks ikke skal ha internett-tilgang en dag pga
3312 eksamen/tentamen, samt en noe enklere brannmurløsning hvor man kan
3313 stenge for en del (få) sider på en enkel måte. Jeg liker godt
3314 Skolelinux sin ideologi om at filteret skal trenes i hodet på eleven –
3315 men av og til skulle jeg ønske at f.eks Facebook og Youtube kunne vært
3316 koblet vekk en periode for å få bedre utnyttelse av tid og
3317 ressurser. Disse to nettstedene er nok mye av årsaken til at mange
3318 lærere holder igjen databruken noe mer enn man kunne ønske.&lt;/p&gt;
3319
3320 &lt;p&gt;&lt;strong&gt;Hvilken fri programvare bruker du til daglig?&lt;/strong&gt;&lt;/p&gt;
3321
3322 Jeg benytter nesten bare fri programvare til daglig. LibreOffice,
3323 Iceweasel (Firefox), Thunderbird til e-post og Gimp til
3324 bildebehandling. Vi har PHP-Nuke-oppsatt hjemmeside. Det eneste som
3325 jeg ikke har fått helt til enda er videoredigering - her må man vel
3326 innrømme at Mac er hakket over, men da er vi igjen over på å se hva
3327 som egner seg best, og ta valg ut fra det. Folk flest lever i
3328 villfarelsen om at regneark HETER Excel og tekstbehandling HETER
3329 Word. Dette er en misforståelse som jeg bruker mye energi på å
3330 diskutere og &quot;åpne sinn&quot; på Microsoft-slaver. Dessverre er det mange
3331 IKT-ansvarlige som også har låst seg på at det eneste saliggjørende er
3332 Bill G sine produkter.
3333
3334 &lt;p&gt;&lt;strong&gt;Hvilken strategi tror du er den rette å bruke for å få
3335 skoler til å ta i bruk fri programvare?&lt;/strong&gt;&lt;/p&gt;
3336
3337 &lt;p&gt;For å komme lenger i utbredelsen av Skolelinux tror jeg det må mer
3338 fram i nasjonale medier, samt komme bedre fram hva økonomien i dette
3339 valget vil være – samt mulighetene. Fri programvare er en berikelse og
3340 gjør oss i stand til å utføre arbeidet i skolen uten å måtte legge
3341 igjen tusener på tusener i Bill Gates lomme.. Få ETT nettsted med
3342 forståelig veiledning av installasjon/oppgradering og ETT forum med
3343 konkrete feilrettinger og problemer, så tror jeg vi kunne kommet et
3344 par skritt framover. Ellers tror jeg bare at ildsjelene må fortsette å
3345 skinne – kanskje flere enn oss følger etter på veien.&lt;/p&gt;

3358 to set up Kmail in Debian Edu Squeze to authenticate using Kerberos,
3359 allowing users to check their local email account without providing
3360 any password. The video is embedded here in quarter size,

3375 <title>Større PC-tetthet i skolen med Skolelinux?</title>
3376 <link>http://people.skolelinux.org/pere/blog/St_rre_PC_tetthet_i_skolen_med_Skolelinux_.html</link>
3377 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/St_rre_PC_tetthet_i_skolen_med_Skolelinux_.html</guid>
3378 <pubDate>Mon, 19 Mar 2012 23:25:00 +0100</pubDate>
3379 <description>&lt;p&gt;Den siste uka har det vært en del skriverier om hvor store
3380 forskjeller det er mellom skolene når det gjelder digital kompetanse.
3381 Et eksempel er
3382 &lt;a href=&quot;http://www.digi.no/891660/bekymret-for-it-i-skolen&quot;&gt;oppslaget
3383 i Digi&lt;/a&gt;. Diskusjonen fikk meg til å bli litt nysgjerrig på om
3384 Linux-skoler har større PC-tettet enn snittet i landet. Grunnlaget
3385 for diskusjonen har vært undersøkelsen
3386 &lt;a href=&quot;https://iktsenteret.no/ressurser/monitor-2011-skolens-digitale-tilstand&quot;&gt;Monitor
3387 2011&lt;/a&gt;, som bruker informasjon fra
3388 &lt;a href=&quot;https://www.wis.no/gsi&quot;&gt;Grunnskolens Informasjonssystem&lt;/a&gt;
3389 (GSI). GSI-data kan lastes ned fra web og jeg lastet ned en Excel-fil
3390 (intet åpen standard-valg tilgjengelig) med navn på alle skoler,
3391 hvilke kommune de befinner seg i og hvor mange elever pr. elev-PC de
3392 har rapportert inn. For å få en ide om svaret trenger jeg deretter å
3393 vite hvilke skoler i landet som bruker Linux, slik at jeg kan slå dem
3394 opp i GSI og finne ut hvor stor PC-tetthet de har.&lt;/p&gt;
3395
3396 &lt;p&gt;Jeg vet om skoler i Balsfjord, Flora, Harstad, Kongsvinger, Narvik,
3397 Nittedal, Nord-Odal, Randaberg og Sunndal som bruker Skolelinux eller
3398 andre Linux-varianter. Jeg tror det er flere enn de 56 skolene jeg
3399 har klart å identifisere de siste dagene, men har ikke klart å få det
3400 bekreftet med offentlige kilder.&lt;/p&gt;
3401
3402 &lt;p&gt;Monitor 2011-rapporteres side 95 forteller at det &quot;ifølge GSI
3403 (20120-2011) er det 3,11 elever per datamaskin når vi tar med alle
3404 grunnskoler (1.-10.trinn)&quot;. For de 56 Linux-skolene jeg har klart å
3405 koble mot informasjon i GSI er det 2,28 elever per elevdatamaskin,
3406 hvilket betyr at det er 36% høyere PC-tetthet på Linux-skoler enn
3407 landsgjennomsnittet. Linux-skolen med høyest tettet blant de jeg har
3408 notert -skole er Flora ungdomsskule i Flora kommune med 0.82 elev
3409 pr. PC (482 elever, 588 elevdatamaskiner).&lt;/p&gt;
3410
3411 &lt;p&gt;Skolelinux gir datamaskiner lengre levetid, og en kan dermed få
3412 flere operative datamaskiner for samme budsjett, i tillegg til en
3413 rekke andre fordeler. Kan det være forklaringen på forskjellen?&lt;/p&gt;
3414
3415 &lt;p&gt;Tallene må tas med en liten klype, da GSI ser ut til å ha endel
3416 feilføringer. Jeg synes i hvert fall en skole med 423 elever og 9
3417 elevmaskiner ser mistenkelig ut. Eller en skole med 346 elever, 0
3418 elevmaskiner, som er et annet ekstremt eksempel jeg fant.&lt;/p&gt;
3419
3420 &lt;p&gt;Takk til Sturle Sunde, Klaus Ade Johnstad, Ole-Anders Andreassen og
3421 Trond Mæhlum for innspill om skoler med Linux.&lt;/p&gt;

3426 <title>Debian Edu interview: John Ingleby</title>

3428 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Debian_Edu_interview__John_Ingleby.html</guid>
3429 <pubDate>Mon, 19 Mar 2012 21:15:00 +0100</pubDate>
3430 <description>&lt;p&gt;&lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu / Skolelinux&lt;/a&gt;
3431 users are spread all across the globe. The second inteview after
3432 &lt;a href=&quot;http://lists.debian.org/debian-edu-announce/2012/03/msg00001.html&quot;&gt;the
3433 Squeeze release&lt;/a&gt; was publised is with John Ingleby, a teacher and
3434 long time Linux user in United Kingdom.&lt;/p&gt;
3435
3436 &lt;p&gt;&lt;strong&gt;Who are you, and how do you spend your days?&lt;/strong&gt;&lt;/p&gt;
3437
3438 &lt;p&gt;I teach ICT part time at the Rudolf Steiner School in Kings
3439 Langley, near London, UK. Previously I worked as a technical
3440 author/trainer while my children attended the school, and I also
3441 contributed to the Schoolforge UK community with the aim of
3442 encouraging UK schools to adopt free/open source software. Five or six
3443 years ago we had about 50 schools interested in some way, but we
3444 weren&#39;t able to convert many of them into sustainable
3445 installations.&lt;/p&gt;
3446
3447 &lt;p&gt;&lt;strong&gt;How did you get in contact with the Skolelinux/Debian Edu
3448 project?&lt;/strong&gt;&lt;/p&gt;
3449
3450 &lt;p&gt;Skolelinux had two representatives at an early Edubuntu meeting in
3451 London which I attended. However at that time our school network had
3452 just been installed using CentOS, LTSP 4 and GNOME. When LTSP 5 came
3453 along we switched to Edubuntu thin client servers so now we have a
3454 mixed environment which includes Windows PCs and student laptops, as
3455 well as their MacBooks and iPads. However, the proprietary systems
3456 have always been rather problematic, and we never built a GUI for the
3457 LDAP server, so when I discovered Skolelinux is configured for all
3458 these things we decided to try it.&lt;/p&gt;
3459
3460 &lt;p&gt;&lt;strong&gt;What do you see as the advantages of Skolelinux/Debian
3461 Edu?&lt;/strong&gt;&lt;/p&gt;
3462
3463 &lt;p&gt;By far the biggest advantage is the Debian Edu community. Apart
3464 from that I have always believed in the same &quot;sustainable computing&quot;
3465 goals that Skolelinux is built on: installing Linux on computers which
3466 would otherwise be thrown away, to provide a reliable, secure and
3467 low-cost IT environment for schools. From my own experience I know
3468 that a part-time person can teach and manage a network of about 25
3469 Linux computers, but it would take much more of my time if we had
3470 proprietary software everywhere.&lt;/p&gt;
3471
3472 &lt;p&gt;&lt;strong&gt;What do you see as the disadvantages of Skolelinux/Debian
3473 Edu?&lt;/strong&gt;&lt;/p&gt;
3474
3475 &lt;p&gt;As a newcomer I&#39;m just finding out who&#39;s who in the community and
3476 how you&#39;re organised, and what your procedures are for dealing with
3477 various things such as editing manual pages and so-on. The only
3478 English language mailing list seems to be for developers as well as
3479 users, so my inbox needs heavy pruning each day!&lt;/p&gt;
3480
3481 &lt;p&gt;&lt;strong&gt;Which free software do you use daily?&lt;/strong&gt;&lt;/p&gt;
3482
3483 &lt;p&gt;Besides the software already mentioned at school we use Samba,
3484 OpenLDAP, CUPS, Nagios and Dansguardian for the network, and on the
3485 desktops we have LibreOffice, Firefox, GIMP and Inkscape. At home I
3486 use Ubuntu and an Android 4 eePad Transformer (but I&#39;m not sure if
3487 that counts...)&lt;/p&gt;
3488
3489 &lt;p&gt;&lt;strong&gt;Which strategy do you believe is the right one to use to
3490 get schools to use free software?&lt;/strong&gt;&lt;/p&gt;
3491
3492 &lt;p&gt;That&#39;s a tough question! For very many years UK schools installed
3493 and taught only proprietary software, so that at the highest levels
3494 the notion of &quot;computer&quot; means simply &quot;proprietary office
3495 applications&quot;. However, schools today are experiencing budget
3496 constraints, and many are having to think hard about upgrading Windows
3497 XP. At the same time, we have students showing teachers how to use
3498 iPads, MacBooks and Android, so the choice of operating system is no
3499 longer quite so automatic. What is more, our government at last
3500 realised that we need people with programming skills, so they&#39;re
3501 putting coding back in the curriculum! And it&#39;s encouraging that the
3502 first 10,000 Raspberry Pi units sold out in 2 hours.&lt;/p&gt;
3503
3504 &lt;p&gt;I don&#39;t really know what strategy is going to get UK schools to use
3505 free software, but building an active community of Skolelinux/Debian
3506 Edu users in this country has to be part of it.&lt;/p&gt;

3511 <title>Writing and translating documentation in Debian Edu</title>
3512 <link>http://people.skolelinux.org/pere/blog/Writing_and_translating_documentation_in_Debian_Edu.html</link>
3513 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Writing_and_translating_documentation_in_Debian_Edu.html</guid>
3514 <pubDate>Fri, 16 Mar 2012 09:55:00 +0100</pubDate>
3515 <description>&lt;p&gt;Documentation in Debian Edu is provided in several languages, and
3516 it is important to make it both easy to contribute and to keep the
3517 translated versions in sync. To do this we have come up with what we
3518 believe is a very efficient work flow.&lt;/p&gt;
3519
3520 &lt;ol&gt;
3521
3522 &lt;li&gt;The documentation is written in a
3523 &lt;a href=&quot;http://moinmo.in&quot;&gt;moinmoin wiki&lt;/a&gt; (see for example
3524 &lt;a href=&quot;http://wiki.debian.org/DebianEdu/Documentation/Squeeze&quot;&gt;the
3525 Squeeze release manual&lt;/a&gt;) with support for exporting the content as
3526 docbook XML.&lt;/li&gt;
3527
3528 &lt;li&gt;This docbook document is given to po4a to extract a gettext style
3529 .pot file with the content, which in turn is used to create .po files
3530 with the translated text.&lt;/li&gt;
3531
3532 &lt;li&gt;The .po files are given to translators, and they can always tell
3533 which part of the original wiki document is new or changed. They can
3534 use their normal translation tools like lokalize or poedit to write
3535 the translation. There is even a system in place to handle translated
3536 images.&lt;/li&gt;
3537
3538 &lt;li&gt;The translated .po files are combined with the original docbook
3539 XML document using po4a to create a translated docbook document.&lt;/li&gt;
3540
3541 &lt;li&gt;The final step is to use all the generated docbook files and
3542 create PDF and HTML version of the original and translated documents.&lt;/li&gt;
3543
3544 &lt;/ol&gt;
3545
3546 &lt;p&gt;This setup work very well, but have a few issues. The biggest
3547 issue is that &lt;a href=&quot;http://moinmo.in/DocBook&quot;&gt;the docbook support
3548 we use in moinmoin&lt;/a&gt; is not actively maintained. The docbook
3549 support is also buggy, and our build system contain workarounds to
3550 make sure the generated docbook is usable despite these bugs.&lt;/p&gt;
3551
3552 &lt;p&gt;If you want to have a look at our setup, it is all there in the
3553 &lt;a href=&quot;http://packages.qa.debian.org/debian-edu-doc&quot;&gt;debian-edu-doc
3554 package&lt;/a&gt;.&lt;/p&gt;

3563 <description>&lt;p&gt;I dag presenterte jeg ny versjon av Skolelinux for NUUGs medlemmer.
3564 &lt;a href=&quot;http://www.hungry.com/~pere/mypapers/20120313-skolelinux-squeeze.html&quot;&gt;Lysark&lt;/a&gt;
3565 er tilgjengelige allerede og
3566 &lt;a href=&quot;http://www.nuug.no/aktiviteter/20120313-skolelinux/&quot;&gt;video-opptak&lt;/a&gt;
3567 kommer så snart videogruppa til NUUG får publisert den. Jeg kom på
3568 endel punkter om nye ting i Squeeze-utgaven under veis som jeg burde
3569 hatt med, og har sikkert skrevet noe tull på lysarkene som jeg ennå
3570 ikke har oppdaget. Denne presentasjonen ble smurt ihop på veldig kort
3571 tid, og jeg rakk ikke finpusse den. Håper den kan være lærerik
3572 likevel.&lt;/p&gt;

3581 <description>&lt;p&gt;Første ut i serien med intervjuer av folk i
3582 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt;-miljøet etter at
3583 &lt;a href=&quot;http://lists.debian.org/debian-edu-announce/2012/03/msg00001.html&quot;&gt;ny
3584 versjon av Skolelinux&lt;/a&gt; ble lansert i helga, er nylig valgte
3585 styremedlem i foreningen
3586 &lt;a href=&quot;http://www.friprogramvareiskolen.no/&quot;&gt;Fri programvare i
3587 Skolen&lt;/a&gt; (FRiSK) som organiserer
3588 Skolelinux-utviklingen og daglig leder i
3589 &lt;a href=&quot;http://www.slxdrift.no/&quot;&gt;Skolelinux Drift AS&lt;/a&gt;, selskapet
3590 prosjektet opprettet som et tilbud til skoler som ønsket en
3591 kommersiell samarbeidsparter. Det bør nevnes at jeg er styremedlem i
3592 Skolelinux Drift AS og styreleder i selskapets hovedeier stiftelsen
3593 &lt;a href=&quot;http://www.linuxiskolen.no/slxdebianlabs/&quot;&gt;SLX Debian Labs&lt;/a&gt;
3594 som beskytter verdiene til Skolelinux-prosjektet, og kjenner Kåre den
3595 veien.&lt;/p&gt;
3596
3597 &lt;p&gt;&lt;strong&gt;Hvem er du, og hva driver du med til daglig?&lt;/strong&gt;&lt;/p&gt;
3598
3599 &lt;p&gt;Jeg har siden januar 2010 vært daglig leder i Skolelinux Drift AS,
3600 som leverer support, installasjon, tilpasning, drift, og opplæring på
3601 Debian Edu / Skolelinux. Fra 2012 er jeg valgt inn som styremedlem i
3602 FRiSK. Min forrige jobb var som KAM i Redpill Linpro (som er en av
3603 eierne i Skolelinux Drift). Før det var jeg daglig leder i et eget 7
3604 manns konsulent selskap som også startet med fri programvare mot
3605 slutten.&lt;/p&gt;
3606
3607 &lt;p&gt;&lt;strong&gt;Hvordan kom du i kontakt med Skolelinux-prosjektet?&lt;/strong&gt;&lt;/p&gt;
3608
3609 &lt;p&gt;Jeg hørte om det først når jeg jobbet i Redpill Linpro. Men jeg
3610 har også en datter som går på en friskole, som også bruker Skolelinux.
3611 Som kjent har ikke friskoler de samme økonomiske rammebetingelsene som
3612 offentlige skoler, så for dem var det det absolutt beste alternativet.
3613 De anser også Skolelinux som et stabilt system, som bare går og går (i
3614 motsetning til det lille Windows-baserte nettverket de har på
3615 admin-siden).&lt;/p&gt;
3616
3617 &lt;p&gt;&lt;strong&gt;Hva er fordelene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
3618
3619 &lt;p&gt;Sentralisert drift av tynne og diskløse arbeidsstasjoner. Således
3620 lydløse og raskere arbeidsstasjoner som er bedre i klasserommet.
3621 Lengre levetid på PC&#39;er. Store besparelser på maskinvare og drift. Og
3622 så klart fjerning av alle lisenskostnader. Personlig synes jeg også at
3623 mange av programmene er bedre enn alternativene. Men dette er ofte en
3624 smakssak og avhengig om man må ha det man er vant til fra før.&lt;/p&gt;
3625
3626 &lt;p&gt;&lt;strong&gt;Hva er ulempene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
3627
3628 &lt;p&gt;For lite kjentskap til løsningen. Noen ganger for dårlig
3629 kompatibilitet med arbeidsstasjoners/bærbare maskiner sine
3630 nettverksdrivere eller skjermkort. Men dette løser vi i skolene ved
3631 standardisering. Ellers er det få, om nesten ingen, av de kjente
3632 maskinvare / infrastruktur leverandørene til fylkes- / kommuner som
3633 tilbyr denne plattformen. Skal dette endre seg så må kommunene selv
3634 sette slike krav til leverandørene.&lt;/p&gt;
3635
3636 &lt;p&gt;&lt;strong&gt;Hvilken fri programvare bruker du til daglig?&lt;/strong&gt;&lt;/p&gt;
3637
3638 &lt;p&gt;Har brukt OpenOffice.org siden starten (2001 ?), Kun Linux på
3639 desktop siden 2005. Bruker i dag Kubuntu, Libreoffice og ymse annet
3640 programvare til ulik kontorbruk som er lett å installere / teste via
3641 alle programarkivene som finnes.&lt;/p&gt;
3642
3643 &lt;p&gt;&lt;strong&gt;Hvilken strategi tror du er den rette å bruke for å få
3644 skoler til å ta i bruk fri programvare?&lt;/strong&gt;&lt;/p&gt;
3645
3646 &lt;p&gt;Fortsette å presentere flere av de gode eksemplene hvor Debian Edu
3647 / Skolelinux brukes i kommuner og enkeltskoler. Vi må få bedre frem
3648 at det er mulig tilknytte både Windows og Mac klienter på denne
3649 plattformen (selv om det vil øke driftskostnadene). Dette gjøres
3650 mange steder. Spesielt er det mange lærere som ønsker å bruke
3651 Windows/Mac-bærbare, gjerne som sin private PC også. Det er også mulig
3652 for kommunen å integrere med Active Directory i stedet for OpenLDAP
3653 som kommer med ut av boksen (selv om også dette øker kostnadene).
3654 Dette vil muligens bidra til å fjerne noe motstand hos noen
3655 potensielle brukere / driftpersonell for å ta i bruk noe
3656 nytt. Fremveksten av mobile brukere og nettbrett går i vår favør.
3657 Brukerne blir kjent og vant til flere nye operativsystemer /
3658 brukergrensesnitt. Så utviklerfellesskapet bør jobbe videre med å
3659 integrere flere nye klienttyper, som ultra lav-kostklienter og
3660 nettbrett (blant annet fri programvare-alternativet
3661 &lt;a href=&quot;http://makeplaylive.com/&quot;&gt;Spark&lt;/a&gt; med
3662 &lt;a href=&quot;http://www.merproject.org/&quot;&gt;Mer OS&lt;/a&gt; og
3663 &lt;a href=&quot;http://plasma-active.org/&quot;&gt;KDE Active Plasma&lt;/a&gt;).&lt;/p&gt;

3687 <title>Debian Edu interview: Nigel Barker</title>
3688 <link>http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Nigel_Barker.html</link>
3689 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Nigel_Barker.html</guid>
3690 <pubDate>Fri, 9 Mar 2012 11:30:00 +0100</pubDate>
3691 <description>&lt;p&gt;Inspired by &lt;a href=&quot;http://raphaelhertzog.com/tag/interview/&quot;&gt;the
3692 interview series&lt;/a&gt; conducted by Raphael, I started a Norwegian
3693 interview series with people involved in the Debian Edu / Skolelinux
3694 community. This was so popular that I believe it is time to move to a
3695 more international audience.&lt;/p&gt;
3696
3697 &lt;p&gt;While &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu and
3698 Skolelinux&lt;/a&gt; originated in France and Norway, and have most users in
3699 Europe, there are users all around the globe. One of those far away
3700 from me is Nigel Barker, a long time Debian Edu system administrator
3701 and contributor. It is thanks to him that Debian Edu is adjusted to
3702 work out of the box in Japan. I got him to answer a few questions,
3703 and am happy to share the response with you. :)
3704
3705
3706 &lt;p&gt;&lt;strong&gt;Who are you, and how do you spend your days?&lt;/strong&gt;&lt;/p&gt;
3707
3708 &lt;p&gt;My name is Nigel Barker, and I am British. I am married to Yumiko,
3709 and we have three lovely children, aged 15, 14 and 4(!) I am the IT
3710 Coordinator at Hiroshima International School, Japan. I am also a
3711 teacher, and in fact I spend most of my day teaching Mathematics,
3712 Science, IT, and Chemistry. I was originally a Chemistry teacher, but
3713 I have always had an interest in computers. Another teacher teaches
3714 primary school IT, but apart from that I am the only computer person,
3715 so that means I am the network manager, technician and webmaster,
3716 also, and I help people with their computer problems. I teach python
3717 to beginners in an after-school club. I am way too busy, so I really
3718 appreciate the simplicity of Skolelinux.&lt;/p&gt;
3719
3720 &lt;p&gt;&lt;strong&gt;How did you get in contact with the Skolelinux/Debian Edu
3721 project?&lt;/strong&gt;&lt;/p&gt;
3722
3723 &lt;p&gt;In around 2004 or 5 I discovered the ltsp project, and set up a
3724 server in the IT lab. I wanted some way to connect it to our central
3725 samba server, which I was also quite poor at configuring. I discovered
3726 Edubuntu when it came out, but it didn&#39;t really improve my setup. I
3727 did various desperate searches for things like &quot;school Linux server&quot;
3728 and ended up in a document called &quot;Drift&quot; something or other. Reading
3729 there it became clear that Skolelinux was going to solve all my
3730 problems in one go. I was very excited, but apprehensive, because my
3731 previous attempts to install Debian had ended in failure (I used
3732 Mandrake for everything - ltsp, samba, apache, mail, ns...). I
3733 downloaded a beta version, had some problems, so subscribed to the
3734 Debian Edu list for help. I have remained subscribed ever since, and
3735 my school has run a Skolelinux network since Sarge.&lt;/p&gt;
3736
3737 &lt;p&gt;&lt;strong&gt;What do you see as the advantages of Skolelinux/Debian
3738 Edu?&lt;/strong&gt;&lt;/p&gt;
3739
3740 &lt;p&gt;For me the integrated setup. This is not just the server, or the
3741 workstation, or the ltsp. Its all of them, and its all configured
3742 ready to go. I read somewhere in the early documentation that it is
3743 designed to be setup and managed by the Maths or Science teacher, who
3744 doesn&#39;t necessarily know much about computers, in a small Norwegian
3745 school. That describes me perfectly if you replace Norway with
3746 Japan.&lt;/p&gt;
3747
3748 &lt;p&gt;&lt;strong&gt;What do you see as the disadvantages of Skolelinux/Debian
3749 Edu?&lt;/strong&gt;&lt;/p&gt;
3750
3751 &lt;p&gt;The desktop is fairly plain. If you compare it with Edubuntu, who
3752 have fun themes for children, or with distributions such as Mint, who
3753 make the desktop beautiful. They create a good impression on people
3754 who don&#39;t need to understand how to use any of it, but who might be
3755 important to the school. School administrators or directors, for
3756 instance, or parents. Even kids. Debian itself usually has ugly
3757 default theme settings. It was my dream a few years back that some
3758 kind of integration would allow Edubuntu to do the desktop stuff and
3759 Debian Edu the servers, but now I realise how impossible that is. A
3760 second disadvantage is that if something goes wrong, or you need to
3761 customise something, then suddenly the level of expertise required
3762 multiplies. For example, backup wasn&#39;t working properly in Lenny. It
3763 took me ages to learn how to set up my own server to do rsync backups.
3764 I am afraid of anything to do with ldap, but perhaps Gosa will
3765 help.&lt;/p&gt;
3766
3767 &lt;p&gt;&lt;strong&gt;Which free software do you use daily?&lt;/strong&gt;&lt;/p&gt;
3768
3769 &lt;p&gt;Nowadays I only use Debian on my personal computers. I have one for
3770 studio work (I play guitar and write songs), running AV Linux
3771 (customised Debian) a netbook running Squeeze, and a bigger laptop
3772 still running Skolelinux Lenny workstation. I have a Tjener in my
3773 house, that&#39;s very useful for the family photos and music. At school
3774 the students only use Skolelinux. (Some teachers and the office still
3775 have windows). So that means we only use free software all day every
3776 day. Open office, The GIMP, Firefox/Iceweasel, VLC and Audacity are
3777 installed on every computer in school, irrespective of OS. We also
3778 have Koha on Debian for the library, and Apache, Moodle, b2evolution
3779 and Etomite on Debian for the www. The firewall is Untangle.&lt;/p&gt;
3780
3781 &lt;p&gt;&lt;strong&gt;Which strategy do you believe is the right one to use to
3782 get schools to use free software?&lt;/strong&gt;&lt;/p&gt;
3783
3784 &lt;p&gt;Current trends are in our favour. Open source is big in industry,
3785 and ordinary people have heard of it. The spread of Android and the
3786 popularity of Apple have helped to weaken the impression that you have
3787 to have Microsoft on everything. People complain to me much less about
3788 file formats and Word than they did 5 years ago. The Edu aspect is
3789 also a selling point. This is all customised for schools. Where is the
3790 Windows-edu, or the Mac-edu? But of course the main attraction is
3791 budget.The trick is to convince people that the quality is not
3792 compromised when you stop paying and use free software instead. That
3793 is one reason why I say the desktop experience is a weakness. People
3794 are not impressed when their USB drive doesn&#39;t work, or their browser
3795 doesn&#39;t play flash, for example.&lt;/p&gt;

3839 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Stopmotion_for_making_stop_motion_animations_on_Linux___reloaded.html</guid>
3840 <pubDate>Sat, 3 Mar 2012 12:50:00 +0100</pubDate>
3841 <description>&lt;p&gt;Many years ago, the &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux
3842 / Debian Edu project&lt;/a&gt; initiated a student project to create a tool
3843 for making stop motion movies. The proposal came from a teacher
3844 needing such tool on Skolelinux. The project, called &quot;stopmotion&quot;,
3845 was manned by two extraordinary students and won a school award and a
3846 national aware with this great project. The project was initiated and
3847 mentored by Herman Robak, and manned by the students Bjørn Erik Nilsen
3848 and Fredrik Berg Kjølstad. They got in touch with people at Aardman
3849 Animation studio and received feedback on how professionals would like
3850 such stopmotion tool to work, and the end result was and is used by
3851 animators around the globe. But as is usual after studying, both got
3852 jobs and went elsewhere, and did not have time to properly tend to the
3853 project, and it has been lingering for a few years now. Until last
3854 year...&lt;/p&gt;
3855
3856 &lt;p&gt;Last year some of the users got together with Herman, and moved the
3857 project to Sourceforge and in effect restarted the project under a new
3858 name,
3859 &lt;a href=&quot;http://sourceforge.net/projects/linuxstopmotion/&quot;&gt;linuxstopmotion&lt;/a&gt;.
3860 The name change was done to make it possible to find the project using
3861 Internet search engines (try to search for &#39;stopmotion&#39; to see what I
3862 mean). I&#39;ve been following
3863 &lt;a href=&quot;https://lists.sourceforge.net/lists/listinfo/linuxstopmotion-community&quot;&gt;the
3864 mailing list&lt;/a&gt; and the improvement already in place and planned for
3865 the future is encouraging. If you want to make stop motion movies.
3866 Check it out. :)&lt;/p&gt;

3876 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt;-miljøet møter vi
3877 denne gangen Frode Danielsen, som er leder for en IT-virksomhet som
3878 passer på IT-løsningen til flere kommuner i Hedmark-området, der noen
3879 av dem bruker Skolelinux i dag.&lt;/p&gt;
3880
3881 &lt;p&gt;&lt;strong&gt;Hvem er du, og hva driver du med til daglig?&lt;/strong&gt;&lt;/p&gt;
3882
3883 &lt;p&gt;Daglig leder i &lt;a href=&quot;http://www.hedmarken-ikt.no/&quot;&gt;Hedmark
3884 IKT&lt;/a&gt;. En interkommunal IKT-virksomhet for Stange, Nord-Odal,
3885 Kongsvinger, Grue, Løten og Hamar kommuner. Vi er 32 ansatte&lt;/p&gt;
3886
3887 &lt;p&gt;&lt;strong&gt;Hvordan kom du i kontakt med Skolelinux-prosjektet?&lt;/strong&gt;&lt;/p&gt;
3888
3889 &lt;p&gt;Vi har vært i kontakt med Skolelinux-prosjektet i flere
3890 sammenhenger, blant annet gjennom et par piloter som ikke har ført til
3891 noe konkret resultat. Nå sist gjennom satsingen på skolelinux i Grue,
3892 Kongsvinger og Nord-Odal.&lt;/p&gt;
3893
3894 &lt;p&gt;&lt;strong&gt;Hva er fordelene med Skolelinux slik du ser det?&lt;/strong&gt;
3895 &lt;br&gt;&lt;strong&gt;Hva er ulempene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
3896
3897 &lt;p&gt;Jeg tror alle løsninger har fordeler og ulemper, litt avhengig av
3898 hvilket ståsted du selv har, så jeg unnlater å svare på dette.&lt;/p&gt;
3899
3900 &lt;p&gt;&lt;strong&gt;Hvilken fri programvare bruker du til daglig?&lt;/strong&gt;&lt;/p&gt;
3901
3902 &lt;p&gt;Ingen for min egen del, men vi har noe fri programvare i våre
3903 løsninger.&lt;/p&gt;
3904
3905 &lt;p&gt;&lt;strong&gt;Hvilken strategi tror du er den rette å bruke for å få
3906 skoler til å ta i bruk fri programvare?&lt;/strong&gt;&lt;/p&gt;
3907
3908 &lt;p&gt;Jeg tror ikke man skal ha en slik strategi. Man bør ha en strategi
3909 basert på å løse fremtidige behov, og velge løsninger som støtter opp
3910 under dette.&lt;/p&gt;

3933 <pubDate>Tue, 21 Feb 2012 07:40:00 +0100</pubDate>
3934 <description>&lt;p&gt;I serien med intervjuer av folk i
3935 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt;-miljøet, får vi nå
3936 høre fra nyvalgt leder i foreningen
3937 &lt;a href=&quot;http://www.friprogramvareiskolen.no/&quot;&gt;Fri programvare i
3938 Skolen&lt;/a&gt; og en av stifterne av Skolelinux-prosjektet.&lt;/p&gt;
3939
3940 &lt;p&gt;&lt;strong&gt;Hvem er du, og hva driver du med til daglig?&lt;/strong&gt;&lt;/p&gt;
3941
3942 &lt;p&gt;Knut Yrvin her. Jobber i Nokia med å fremme rammeverket Qt og QML
3943 med tilhørende utviklerverktøy. Rollen er som leder av
3944 friprog-samfunn. I fjor var jeg med å legge om utviklingen av Qt til
3945 åpen forvaltning. På den måten kan alle som bidrar til Qt gjøre det
3946 på like vilkår. Nå er det
3947 &lt;a href=&quot;http://labs.qt.nokia.com/2011/12/22/qt-5-%E2%80%93-a-look-back-at-the-numbers/&quot;&gt;over
3948 1000 utviklere&lt;/a&gt; som bidrar til Qt. Med overgangen til åpen
3949 forvaltning er utviklingen av Qt mer åpen enn Linux-kjernen.&lt;/p&gt;
3950
3951 &lt;p&gt;&lt;strong&gt;Hvordan kom du i kontakt med Skolelinux-prosjektet?&lt;/strong&gt;&lt;/p&gt;
3952
3953 &lt;p&gt;Jeg var en av initiativtagerne til Skolelinux i 2001. Skolene slet
3954 med både utstyr og Internett-tilgang. De klarte ikke å møte
3955 forventningene til data i skolen. Driften av PC-ene var uholdbar. Som
3956 regel hadde rektor pekt ut en ivrig lærer til å passe på PC-ene,
3957 gjerne naturfaglæreren. Mange lærere jobbet mye ubetalt overtid for å
3958 vedlikeholde 30-40 datamaskiner på hver sin skole. Med 300 elever og
3959 lærere som brukere, blir det fort mye mer arbeid enn de 4-8 timene de
3960 kunne bruke på PC-drift. Skolene hadde kun en femtedel av
3961 IT-budsjettet som ble brukt på PC-ene i rådhuset.&lt;/p&gt;
3962
3963 &lt;p&gt;Vi erfarte at skolene hadde mye datautstyr som stod ubrukt. Skolene
3964 manglet penger til Microsoft-lisenser. Selv med solide skolerabatter,
3965 kostet Microsoft-lisensene gjerne like mye som PC-ene i seg selv over
3966 en periode på 5-6 år.&lt;/p&gt;
3967
3968 &lt;p&gt;Viktigheten av språklig mangfold og pedagogiske programmer var også
3969 viktig for oss. Vi oversatte mange skoleaktuelle programmer til
3970 nynorsk, nordsamisk og bokmål. Dette lenge før andre tok denne
3971 oppgaven seriøst. Allerede etter ett år hadde vi etablert et helt
3972 arsenal av skoleaktuelle programmer på nynorsk, bokmål og
3973 nordsamisk. Vi spredde vår ide om språklig mangfold til de andre frie
3974 prosjekter internasjonalt. Resultatene ser vi i mange land. Det er de
3975 frie programmene som kommer på brukernes morsmål. Det er en av flere
3976 gode grunner til at fri programvare som LibreOffice, VLC, KDE og
3977 Firefox konkurrerer ut godseid programvare mange steder i verden.&lt;/p&gt;
3978
3979 &lt;p&gt;&lt;strong&gt;Hva er fordelene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
3980
3981 &lt;p&gt;Fordelene er at Skolelinux tilbyr over 100 skoleaktuelle programmer
3982 på de norske språkene, uten ett øre i lisenskostnader. Systemet gir
3983 enormt lave driftskostnader med diskløse arbeidsstasjoner og bærbare
3984 med roaming. Skolelinux krever også mindre av maskinvaren.&lt;/p&gt;
3985
3986 &lt;p&gt;Man kan fint kjøre systemet med 512 MB RAM på en bærbar PC sammen
3987 med en nettvideo i nettleseren og en presentasjon med
3988 LibreOffice. Konkurrerende system krever fort 2 GB RAM for å få til
3989 noe tilsvarende uten at det går ufattelig tregt. Skal man gjøre noe
3990 nyttig, krever konkurrentene til Linux mye større harddisk. Skoler har
3991 rapportert at de fort har fått 50% flere nye maskiner om de velger
3992 Linux. Dette i tillegg til de årlige besparelsene ved å unngå
3993 lisensbetaling til godseid programvare.&lt;/p&gt;
3994
3995 &lt;p&gt;De lave driftskostnadene gjør at delstater i Europa har titusener
3996 av datamaskiner med Skolelinux i skolen. F.eks. er det under ti
3997 personer som drifter 70.000 PC-systemer i skolene i Extremadura i
3998 Spania. Det er slett ikke uvanlig at norske kommuner har 1500-2000
3999 datamaskiner med Skolelinux. Driften tar ett årsverk. Slår flere
4000 kommuner seg sammen, kan de få samme sentraliserte stordriftsfordeler
4001 som delstater i Tyskland og Spania. Delstater som kjører Skolelinux
4002 på alle skolene. Bare noen få personer sentraldrifter titusenvis av
4003 PC-er.&lt;/p&gt;
4004
4005 &lt;p&gt;&lt;strong&gt;Hva er ulempene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
4006
4007 &lt;p&gt;Den største ulempen for Skolelinux er motstand mot Linux fra
4008 IT-sjefer i det offentlige. Dette er ledere som holder innlegg som
4009 snytt ut av evangelist-håndboka til Microsoft. Dette gjøres i ett
4010 arbeidsmarked med stor vekst i etterspørselen etter Linux-fagfolk i
4011 privat sektor. Etterspørselen har økt mer enn noe annet tekniske yrke
4012 siste tiåret. Åtte av ti ledere vil ansette Linux-fagfolk i 2012,
4013 rapporterer jobbnettstedet Dice.com på oppdrag av Linux
4014 Foundation.&lt;/p&gt;
4015
4016 &lt;p&gt;Det mangler 16.000 ingeniører og IKT-fagfolk i Norge rapporterte
4017 arbeids- og velferdsetaten NAV. Linux-fagfolk kan velge svært
4018 interessante jobber med alt fra apps på ledende mobilsystem laget med
4019 Linux, sky- tjenester eller web-applikasjoner. De raskest voksende
4020 teknologiselskapene i verden er ute etter Linux-fagfolk. Det være seg
4021 Amazon, Google, Facebook og IBM for å nevne noen. Linux er kritisk
4022 for å sikre veksten i markedet. Det sier seg selv at lønningene og
4023 jobbmulighetene er bedre enn for andre tekniske yrker.&lt;/p&gt;
4024
4025 &lt;p&gt;Skal man lage apps for mobilen, smart-TV-en eller
4026 underholdningssystemet i bilen eller på flyet, er det Linux som
4027 gjelder. Med en slik konkurranse om Linux-kompetansen, kombinert med
4028 motstanden mot Linux hos mange IT-sjefer i offentlig sektor, så
4029 hindrer kommunene rekruttering av flere Linux- fagfolk. Skolene blir
4030 tvunget til å velge dyrere og mindre komplette IT-system. De har
4031 blitt hengende igjen slik IT var på begynnelsen av 2000- tallet. Dette
4032 fordi IT-ledere ikke har tilpasset seg markedet det siste tiåret.&lt;/p&gt;
4033
4034 &lt;p&gt;Når det er sagt, er Skolelinux svært enkelt å lære seg også for de
4035 som ikke kan. Det viser alle lærerne som drifter systemet for
4036 hundrevis og tusenvis av systemer. Det meste er på plass rett ut av
4037 boksen. I tillegg er det solid med dokumentasjon med god hjelp på
4038 nettet. Det er mange kommuner som har ansatt en lærer som først lærte
4039 Skolelinux på sin skole, for så å drifte alle PC-ene i kommunen med
4040 Skolelinux. Det kan fort være snakk om 1000-3000 datamaskiner på 10-15
4041 skoler som sentraldriftes med en stilling. Står man ordentlig fast,
4042 kan man også kjøpe profesjonell hjelp fra selskap som støtter
4043 Skolelinux. Det er flere slike selskap i Norge og i utlandet.&lt;/p&gt;
4044
4045 &lt;p&gt;&lt;strong&gt;Hvilken fri programvare bruker du til daglig?&lt;/strong&gt;&lt;/p&gt;
4046
4047 &lt;p&gt;Qt SDK, LibreOffice, Firefox, VLC og KDE-skrivebordet. Dette på et
4048 Debian-basert GNU/Linux-system. Jeg bruker også noen morsomme
4049 3D-spill. Idag kan jeg velge mellom over 30.000 Linux-programmer. Det
4050 finnes ikke tid i livet å undersøke alle valgmulighetene. Derfor er
4051 det bra med Skolelinux i skolen, da utvalget av programmer er
4052 begrenset til hva som er aktuelt i skolefagene.&lt;/p&gt;
4053
4054 &lt;p&gt;&lt;strong&gt;Hvilken strategi tror du er den rette å bruke for å få
4055 skoler til å ta i bruk fri programvare?&lt;/strong&gt;&lt;/p&gt;
4056
4057 &lt;p&gt;Vi må selge hele Skolelinux forhåndsinstallert på maskinvare i hele
4058 pakker med 50-100-1000 PC-klienter med servere. Dette kan selges til
4059 enkeltskoler eller hele kommuner. Pakken må inneholde tjenermaskiner,
4060 svært rimelige diskløse arbeidsstasjoner, nettbrett med Plasma Active,
4061 og bærbare med roaming. Alt er godt testet med Debian. I et slikt
4062 anbud er det mulig å legge til sentraliserte drifts- og
4063 støttetjenester.&lt;/p&gt;
4064
4065 &lt;p&gt;Man bør også selge sky-tjenester som læreadministrative systemet
4066 Moodle og driftsovervåking. I tillegg så bør man slenge seg på med
4067 presentasjoner de gangene LibreOffice og andre friprog-produkter
4068 selges til kommuner.&lt;/p&gt;

4090 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Skolelinux_intervju__Olav_Dahlum.html</guid>
4091 <pubDate>Sat, 18 Feb 2012 10:40:00 +0100</pubDate>
4092 <description>&lt;p&gt;I serien med intervjuer av folk i
4093 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt;-miljøet, får vi nå
4094 høre fra et nyvalgt medlem i foreningen
4095 &lt;a href=&quot;http://www.friprogramvareiskolen.no/&quot;&gt;Fri programvare i
4096 Skolen&lt;/a&gt;.&lt;/p&gt;
4097
4098 &lt;p&gt;&lt;strong&gt;Hvem er du, og hva driver du med til daglig?&lt;/strong&gt;&lt;/p&gt;
4099
4100 &lt;p&gt;Jeg heter Olav Dahlum, og er frilans oversetter, tester,
4101 prosjektleder og bruker av fri og åpen programvare som
4102 LibreOffice. Jeg er også et av styremedlemmene i FRISK.&lt;/p&gt;
4103
4104 &lt;p&gt;&lt;strong&gt;Hvordan kom du i kontakt med Skolelinux-prosjektet?&lt;/strong&gt;&lt;/p&gt;
4105
4106 &lt;p&gt;Jeg kom i kontakt med prosjektet i 2009, da jeg ble ansatt i
4107 stiftelsen Åpne kontorprogram på norsk for å oversette og teste den
4108 norske utgaven av OpenOffice.org. Arbeidet har hele tiden vært
4109 koordinert sammen med Skolelinux, og mange av de samme menneskene er
4110 involvert, så på den måten ble jeg en del av den utvidede
4111 familien.&lt;/p&gt;
4112
4113 &lt;p&gt;&lt;strong&gt;Hva er fordelene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
4114
4115 &lt;p&gt;Skolelinux handler i likhet med utdanningssektoren om å dele
4116 kunnskap med andre, og det er dette som er hovedstyrken til
4117 prosjektet. Selv om Skolelinux hovedsaklig er involvert i utvikling
4118 av programvare, er det også et sted der man kan utfolde seg uavhengig
4119 av bakgrunn og ferdigheter.&lt;/p&gt;
4120
4121 &lt;p&gt;&lt;strong&gt;Hva er ulempene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
4122
4123 &lt;p&gt;Liten utbredelse og manglende støtte fra leverandører som leverer
4124 pedagogisk programvare til skolebruk. Kunne kanskje hatt flere
4125 verktøy som letter administrasjonen ytterligere, slik at også mindre
4126 erfarne databrukere kan utføre lett vedlikehold og rutinejobber.&lt;/p&gt;
4127
4128 &lt;p&gt;&lt;strong&gt;Hvilken fri programvare bruker du til daglig?&lt;/strong&gt;&lt;/p&gt;
4129
4130 &lt;p&gt;Jeg er nesten forpliktet til å si at jeg bruker LibreOffice... Jeg
4131 bruker forøvrig frie og åpne operativsystemer basert på
4132 operativsystemkjernen Linux, for tiden openSUSE 12,1 med KDE4. Men
4133 hvis jeg skal dra fram noen flere eksempler så er nok Mozilla Firefox
4134 og Thunderbird to av de jeg bruker mest. I tillegg er jeg en flittig
4135 bruker av OpenSSH, Irssi, Midnight Commander, Git, Subversion,
4136 Translation Toolkit og Super Maryo Chronicles (litt gøy skal man ha,
4137 og med to håndkontroller liggende er det ikke til å unngå).&lt;/p&gt;
4138
4139 &lt;p&gt;&lt;strong&gt;Hvilken strategi tror du er den rette å bruke for å få
4140 skoler til å ta i bruk fri programvare?&lt;/strong&gt;&lt;/p&gt;
4141
4142 &lt;p&gt;Vi må få leverandører av pedagogisk programvare med på laget, men
4143 også utvikle vår egen tilpasset det norske markedet. Det er også
4144 mulig å involvere utdanningssektoren direkte i arbeidet, for eksempel
4145 gjennom studentprosjekter der elevene selv er med å utforme
4146 programvare direkte eller indirekte gjennom aktive bidrag. Dette gjør
4147 ikke bare samarbeidet tettere, men fokuset på standarder og friheten
4148 til å velge sin egen løsning vil kanskje stimulere interessen for
4149 framtidig deltakelse i bransjen. Vi som driver med fri og åpen
4150 programvare ønsker oss ikke rene konsumenter, men tenkende og
4151 selvstendige individer som kan være med å skape sin egen fremtid.&lt;/p&gt;

4156 <title>Automatic proxy configuration with Debian Edu / Skolelinux</title>
4157 <link>http://people.skolelinux.org/pere/blog/Automatic_proxy_configuration_with_Debian_Edu___Skolelinux.html</link>
4158 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Automatic_proxy_configuration_with_Debian_Edu___Skolelinux.html</guid>
4159 <pubDate>Mon, 13 Feb 2012 23:40:00 +0100</pubDate>
4160 <description>&lt;p&gt;New in the Squeeze version of
4161 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu / Skolelinux&lt;/a&gt; is the
4162 ability for clients to automatically configure their proxy settings
4163 based on their environment. We want all systems on the client to use
4164 the WPAD based proxy definition fetched from &lt;tt&gt;http://wpad/wpad.dat&lt;/tt&gt;, to
4165 allow sites to control the proxy setting from a central place and make
4166 sure clients do not have hard coded proxy settings. The schools can
4167 change the global proxy setting by editing
4168 &lt;tt&gt;tjener:/etc/debian-edu/www/wpad.dat&lt;/tt&gt; and the change propagate
4169 to all Debian Edu clients in the network.&lt;/p&gt;
4170
4171 &lt;p&gt;The problem is that some systems do not understand the WPAD system.
4172 In other words, how do one get from a WPAD file like this (this is a
4173 simple one, they can run arbitrary code):&lt;/p&gt;
4174
4175 &lt;blockquote&gt;&lt;pre&gt;
4176 function FindProxyForURL(url, host)
4177 {
4178 if (!isResolvable(host) ||
4179 isPlainHostName(host) ||
4180 dnsDomainIs(host, &quot;.intern&quot;))
4181 return &quot;DIRECT&quot;;
4182 else
4183 return &quot;PROXY webcache:3128; DIRECT&quot;;
4184 }
4185 &lt;/pre&gt;&lt;/blockquote&gt;
4186
4187 &lt;p&gt;to a proxy setting in the process environment looking like this:&lt;/p&gt;
4188
4189 &lt;blockquote&gt;&lt;pre&gt;
4190 http_proxy=http://webcache:3128/
4191 ftp_proxy=http://webcache:3128/
4192 &lt;/pre&gt;&lt;/blockquote&gt;
4193
4194 &lt;p&gt;To do this conversion I developed a perl script that will execute
4195 the javascript fragment in the WPAD file and return the proxy that
4196 would be used for
4197 &lt;tt&gt;&lt;a href=&quot;http://www.debian.org/&quot;&gt;http://www.debian.org/&lt;/a&gt;&lt;/tt&gt;,
4198 and insert this extracted proxy URL in &lt;tt&gt;/etc/environment&lt;/tt&gt; and
4199 &lt;tt&gt;/etc/apt/apt.conf&lt;/tt&gt;. The perl script wpad-extract work just
4200 fine in Squeeze, but in Wheezy the library it need to run the
4201 javascript code is &lt;a href=&quot;http://bugs.debian.org/631045&quot;&gt;no longer
4202 able to build&lt;/a&gt; because the C library it depended on is now a C++
4203 library. I hope someone find a solution to that problem before Wheezy
4204 is frozen. An alternative would be for us to rewrite wpad-extract to
4205 use some other javascript library currently working in Wheezy, but no
4206 known alternative is known at the moment.&lt;/p&gt;
4207
4208 &lt;p&gt;This automatic proxy system allow the roaming workstation (aka
4209 laptop) setup in Debian Edu/Squeeze to use the proxy when the laptop
4210 is connected to the backbone network in a Debian Edu setup, and to
4211 automatically use any proxy present and announced using the WPAD
4212 feature when it is connected to other networks. And if no proxy is
4213 announced, direct connections will be used instead.&lt;/p&gt;
4214
4215 &lt;p&gt;Silently using a proxy announced on the network might be a privacy
4216 or security problem. But those controlling DHCP and DNS on a network
4217 could just as easily set up a transparent proxy, and force all HTTP
4218 and FTP connections to use a proxy anyway, so I consider that
4219 distinction to be academic. If you are afraid of using the wrong
4220 proxy, you should avoid connecting to the network in question in the
4221 first place. In Debian Edu, the proxy setup is updated using dhcp and
4222 ifupdown hooks, to make sure the configuration is updated every time
4223 the network setup changes.&lt;/p&gt;
4224
4225 &lt;p&gt;The WPAD system is documented in a
4226 &lt;a href=&quot;http://tools.ietf.org/html/draft-ietf-wrec-wpad-01&quot;&gt;IETF
4227 draft&lt;/a&gt; and a
4228 &lt;a href=&quot;http://en.wikipedia.org/wiki/Web_Proxy_Autodiscovery_Protocol&quot;&gt;Wikipedia
4229 page&lt;/a&gt; for those that want to learn more.&lt;/p&gt;

4236 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Skolelinux_intervju__Axel_Bojer.html</guid>
4237 <pubDate>Tue, 7 Feb 2012 14:50:00 +0100</pubDate>
4238 <description>&lt;p&gt;I serien med intervjuer av folk i
4239 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt;-miljøet har jeg
4240 fått en av oversetterne som har vært med siden starten i tale.&lt;/p&gt;
4241
4242 &lt;p&gt;&lt;strong&gt;Hvem er du, og hva driver du med til daglig?&lt;/strong&gt;&lt;/p&gt;
4243
4244 &lt;p&gt;Jeg heter Axel Bojer og er datalærer, tysklærer, oversetter med
4245 mere.&lt;/p&gt;
4246
4247 &lt;p&gt;&lt;strong&gt;Hvordan kom du i kontakt med Skolelinux-prosjektet?&lt;/strong&gt;&lt;/p&gt;
4248
4249 &lt;p&gt;Tror jeg så en annonsering på nettet i slutten av 2001 og ville
4250 være med som oversetter. Jeg kom med på en utviklersamling og
4251 prosjektet var da helt i starten. Det var spennende å være med mens
4252 prosjektet vokste til og utviklet seg.&lt;/p&gt;
4253
4254 &lt;p&gt;Jeg har «alltid» vært språkinteressert og hadde nettopp startet med
4255 Linux og tror jeg tenkte det passet å bidra. Var også glad for å få
4256 en Debian-distribusjon, og ville gjerne bruke den selv. Til å begynne
4257 med brukte jeg først Mandrake og så Debian. Og siden jeg oppdaget at
4258 det ikke var noen mulighet for å bruke den som enkeltstående i lang
4259 tid, så gikk jeg etterhvert over til Kubuntu&lt;/p&gt;
4260
4261 &lt;p&gt;&lt;strong&gt;Hva er fordelene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
4262
4263 &lt;p&gt;Løsningen er forholdsvis lett å sette opp, gratis, fri programvare
4264 og gjør det mulig å gjenbruke eldre maskiner. Det fine med Debian er
4265 at det er stabilt og har en veldig stor mengde programmer. Jeg liker
4266 også apt. :-) Jeg liker også friheten ved Linux og muligheten til å
4267 delta og forme sin egen datahverdag.&lt;/p&gt;
4268
4269 &lt;p&gt;&lt;strong&gt;Hva er ulempene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
4270
4271 &lt;p&gt;Skolelinux er for lite kjent og for sent ute med å gi ut nye
4272 versjoner.&lt;/p&gt;
4273
4274 &lt;p&gt;Da jeg selv i hovedsak bruker Kubuntu, så kan jeg egentlig ikke
4275 svare så detaljert rundt ulempene med Skolelinux. Hovedårsaken til at
4276 jeg bruker Kubuntu er nok at da vi begynte med det mener jeg det ikke
4277 var noen annen løsning. «Vandrende arbeidsstasjon» mener jeg ikke
4278 fantes da. Dessuten ville jeg ha siste versjon, da den KDE-versjonen
4279 som var i Skolelinux den gangen var en god del enklere (tror det var
4280 KDE 2) var dårligere i mine øyne enn versjon 3.&lt;/p&gt;
4281
4282 &lt;p&gt;&lt;strong&gt;Hvilken fri programvare bruker du til daglig?&lt;/strong&gt;&lt;/p&gt;
4283
4284 &lt;p&gt;Jeg bruker blant annet Kubuntu, LibreOffice, Thunderbird, Firefox,
4285 Kate, &lt;a href=&quot;http://comix.sourceforge.net/&quot;&gt;Comix&lt;/a&gt; og Konsole. Og
4286 en hel haug andre ved behov :-)&lt;/p&gt;
4287
4288 &lt;p&gt;Har oversatt Comix selv, men det er jo ikke skjedd noe med Comix
4289 siden 2009, så den er det nok bare jeg som har. Om andre vil ha den
4290 gir jeg den gjerne videre. Ser at noen har startet på
4291 &lt;a href=&quot;http://mcomix.sourceforge.net/&quot;&gt;MComix&lt;/a&gt; siden jeg så på så
4292 på dette sist, så nå er jeg igang med å teste og oversette den
4293 også.&lt;/p&gt;
4294
4295 &lt;p&gt;&lt;strong&gt;Hvilken strategi tror du er den rette å bruke for å få
4296 skoler til å ta i bruk fri programvare?&lt;/strong&gt;&lt;/p&gt;
4297
4298 &lt;p&gt;Det viktigste er å forankre beslutningen i kollegiet og med de som
4299 er ansvarlige for å vedlikeholde og bruke datamaskinene. Flest mulig
4300 bør være med på å holde det (sosialt) vedlike, kjenne og støtte
4301 prinsippene. Som enkeltmannsprosjekt blir det lett veldig sårbart,
4302 særlig når (Skole)linux ennå i stor grad er en motkultur og ikke noe
4303 en stor nok andel av beslutningstakere, brukere osv kjenner til og
4304 bruker.&lt;/p&gt;
4305
4306 &lt;p&gt;Jeg tror det viktigste er å fortsette å holde fri programvare godt,
4307 oppdatert, minimere antall feil, ha en god kontakt med brukerne og
4308 attraktivt og spennende programmer. Beholde alt som er bra og ha det
4309 tilgjengelig samtidig som man tilbyr det nyeste og rareste for de som
4310 vil ha det.&lt;/p&gt;

4315 <title>Saving power with Debian Edu / Skolelinux using shutdown-at-night</title>
4316 <link>http://people.skolelinux.org/pere/blog/Saving_power_with_Debian_Edu___Skolelinux_using_shutdown_at_night.html</link>
4317 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Saving_power_with_Debian_Edu___Skolelinux_using_shutdown_at_night.html</guid>
4318 <pubDate>Sun, 5 Feb 2012 09:45:00 +0100</pubDate>
4319 <description>&lt;p&gt;Since the Lenny version of
4320 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu / Skolelinux&lt;/a&gt;, a
4321 feature to save power have been included. It is as simple as it is
4322 practical: Shut down unused clients at night, and turn them on again
4323 in the morning. This is done using the
4324 &lt;a href=&quot;http://packages.qa.debian.org/s/shutdown-at-night.html&quot;&gt;shutdown-at-night&lt;/a&gt; Debian package.&lt;/p&gt;
4325
4326 &lt;p&gt;To enable this feature on a client, the machine need to be added to
4327 the netgroup shutdown-at-night-hosts. For Debian Edu, this is done in
4328 LDAP, and once this is in place, the machine in question will check
4329 every hour from 16:00 until 06:00 to see if the machine is unused, and
4330 shut it down if it is. If the hardware in question is supported by
4331 the
4332 &lt;a href=&quot;http://packages.qa.debian.org/n/nvram-wakeup.html&quot;&gt;nvram-wakeup&lt;/a&gt;
4333 package, the BIOS is told to turn the machine back on around 07:00 +-
4334 10 minutes. If this isn&#39;t working, one can configure wake-on-lan to
4335 try to turn on the client. The wake-on-lan option is only documented
4336 and not enabled by default in Debian Edu.&lt;/p&gt;
4337
4338 &lt;p&gt;It is important to not turn all machines on at once, as this can
4339 blow a fuse if several computers are connected to the same fuse like
4340 the common setup for a classroom. The nvram-wakeup method only work
4341 for machines with a functioning hardware/BIOS clock. I&#39;ve seen old
4342 machines where the BIOS battery were dead and the hardware clock were
4343 starting from 0 (or was it 1990?) every boot. If you have one of
4344 those, you have to turn on the computer manually.&lt;/p&gt;
4345
4346 &lt;p&gt;The shutdown-at-night package is completely self contained, and can
4347 also be used outside the Debian Edu environment. For those without a
4348 central LDAP server with netgroups, one can instead touch the file
4349 &lt;tt&gt;/etc/shutdown-at-night/shutdown-at-night&lt;/tt&gt; to enable it.
4350 Perhaps you too can use it to save some power?&lt;/p&gt;

4355 <title>Third beta version of Debian Edu / Skolelinux based on Squeeze</title>
4356 <link>http://people.skolelinux.org/pere/blog/Third_beta_version_of_Debian_Edu___Skolelinux_based_on_Squeeze.html</link>
4357 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Third_beta_version_of_Debian_Edu___Skolelinux_based_on_Squeeze.html</guid>
4358 <pubDate>Sat, 4 Feb 2012 13:25:00 +0100</pubDate>
4359 <description>&lt;p&gt;I am happy to announce that finally we managed today to wrap up and
4360 publish the third beta version of
4361 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu / Skolelinux&lt;/a&gt; based
4362 on Squeeze. If you want to test a LDAP backed Kerberos server with
4363 out of the box PXE configuration for running diskless machines and
4364 installing new machines, check it out. If you need a software
4365 solution for your school, check it out too. The full announcement is
4366 &lt;a href=&quot;http://lists.debian.org/debian-edu-announce/2012/02/msg00000.html&quot;&gt;available&lt;/a&gt;
4367 on the project announcement list.&lt;/p&gt;
4368
4369 &lt;p&gt;I am very happy to report these changes and improvements since
4370 beta2 (there are more, see announcement for full list):&lt;/p&gt;
4371
4372 &lt;ul&gt;
4373
4374 &lt;li&gt;It is now possible to change the pre-configured IP subnet from
4375 10.0.0.0/8 to something else by using the subnet-change tool after
4376 the installation.&lt;/li&gt;
4377
4378 &lt;li&gt;Too full partitions are now automatically extended on the Main
4379 Server, based on the rules specified in /etc/fsautoresizetab.&lt;/li&gt;
4380
4381 &lt;li&gt;The CUPS queues are now automatically flushed every night, and all
4382 disabled queues are restarted every hour. This should cut down on
4383 the amount of manual administration needed for printers.&lt;/li&gt;
4384
4385 &lt;li&gt;The set of initial users have been changed. Now a personal user
4386 for the local system administrator is created during installation
4387 instead of the previously created localadmin and super-admin users,
4388 and this user is granted administrative privileges using group
4389 membership. This reduces the number of passwords one need to keep
4390 up to date on the system.&lt;/li&gt;
4391
4392 &lt;/ul&gt;
4393
4394 &lt;p&gt;The new main server seem to work so well that I am testing it as my
4395 private DNS/LDAP/Kerberos/PXE/LTSP server at home. I will use it look
4396 for issues we could fix to polish Debian Edu even further before the
4397 final Squeeze release is published.&lt;/p&gt;
4398
4399 &lt;p&gt;Next weekend the project organise a
4400 &lt;a href=&quot;http://lists.debian.org/debian-edu-announce/2012/01/msg00001.html&quot;&gt;developer
4401 gathering&lt;/a&gt; in Oslo. We will continue the work on the Squeeze
4402 version, and start initial planning for the Wheezy version. Perhaps I
4403 will see you there?&lt;/p&gt;

4408 <title>Handling non-free firmware in Debian Edu/Squeeze</title>
4409 <link>http://people.skolelinux.org/pere/blog/Handling_non_free_firmware_in_Debian_Edu_Squeeze.html</link>
4410 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Handling_non_free_firmware_in_Debian_Edu_Squeeze.html</guid>
4411 <pubDate>Fri, 27 Jan 2012 23:30:00 +0100</pubDate>
4412 <description>&lt;p&gt;With some computer hardware, one need non-free firmware blobs.
4413 This is the sad fact of todays computers. In the next version of
4414 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu / Skolelinux&lt;/a&gt; based
4415 on Squeeze, we provide several scripts and modifications to make
4416 firmware blobs easier to handle. The common use case I run into is a
4417 laptop with a wireless network card requiring non-free firmware to
4418 work, but there are other use cases as well.&lt;/p&gt;
4419
4420 &lt;p&gt;First and foremost, Debian Edu provide ISO images for DVD and CD
4421 with all firmware packages in the Debian sections main and non-free
4422 included, to ensure debian-installer find and can install all of them
4423 during installation. This take care firmware for network devices used
4424 by the installer when installing from from local media. But for
4425 example multimedia devices are not activated in the installer and are
4426 not taken care of by this.&lt;/p&gt;
4427
4428 &lt;p&gt;For non-network devices, we provide the script
4429 &lt;tt&gt;/usr/share/debian-edu-config/tools/auto-addfirmware&lt;/tt&gt; which
4430 search through the &lt;tt&gt;dmesg&lt;/tt&gt; output for drivers requesting extra
4431 firmware. The firmware file name is looked up in the Contents-ARCH.gz
4432 file available in the package repository, and the packages providing
4433 the requested firmware file(s) is installed. I have proposed to do
4434 something similar in debian-installer (BTS report
4435 &lt;a href=&quot;http://bugs.debian.org/655507&quot;&gt;#655507&lt;/a&gt;), to allow PXE
4436 installs of Debian to handle firmware installation better. Run the
4437 script as root from the command line to fetch and install the needed
4438 firmware packages.&lt;/p&gt;
4439
4440 &lt;p&gt;Debian Edu provide PXE installation of Debian out of the box, and
4441 because some machines need firmware to get their network cards
4442 working, the installation initrd some times need extra firmware
4443 included to be able to install at all. To fill the PXE installation
4444 initrd with extra firmware, the
4445 &lt;tt&gt;/usr/share/debian-edu-config/tools/pxe-addfirmware&lt;/tt&gt; script is
4446 provided. Again, just run it as root on the command line to fill the
4447 PXE initrd with firmware packages.&lt;/p&gt;
4448
4449 &lt;p&gt;Last, some LTSP clients might also need firmware to get their
4450 network cards working. For this,
4451 &lt;tt&gt;/usr/share/debian-edu-config/tools/ltsp-addfirmware&lt;/tt&gt; is
4452 provided to update the LTSP initrd with firmware blobs. It is used
4453 the same way as the other firmware related tools.&lt;/p&gt;
4454
4455 &lt;p&gt;At the moment, we do not run any of these during installation. We
4456 do not know if this is acceptable for the local administrator to use
4457 non-free software, and it is their choice.&lt;/p&gt;
4458
4459 &lt;p&gt;We plan to release beta3 this weekend. You might want to give it a
4460 try.&lt;/p&gt;

4465 <title>Skjermbilder fra nordsamisk installasjon av Skolelinux/Squeeze</title>

4467 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Skjermbilder_fra_nordsamisk_installasjon_av_Skolelinux_Squeeze.html</guid>
4468 <pubDate>Thu, 26 Jan 2012 20:00:00 +0100</pubDate>
4469 <description>&lt;p&gt;For morro skyld har jeg gjennomført en nordsamisk installasjon for
4470 neste utgave av &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt;
4471 (Squeeze) og knipset skjermbilder av resultatet.&lt;/p&gt;
4472
4473 &lt;p&gt;Som en kan se der er det noen oversettelser som mangler. Det hadde
4474 vært hyggelig hvis alle tekstene som vises i Skolelinux-installasjonen
4475 ble oversatt til nordsamisk, men for å få det til må noen som forstår
4476 språket melde seg til dyst. Det er mangel på nordsamiske oversettere
4477 av fri programvare. Hvis noen starter raskt, så bør en rekke å
4478 fullføre Wheezy-utgaven før den gis ut. :)&lt;/p&gt;
4479
4480 &lt;p&gt;Se &lt;a href=&quot;http://d-i.debian.org/l10n-stats/&quot;&gt;oversetterstatistikk for
4481 debian installer&lt;/a&gt; for detaljert status. Jeg har tipset
4482 &lt;a href=&quot;https://lister.ping.uio.no/mailman/listinfo/i18n-sme&quot;&gt;epostlisten for samiskoversettelser&lt;/a&gt;,
4483 men det har vært veldig liten aktivitet der de siste årene.&lt;/p&gt;

4511 <title>Setting up a new school with Debian Edu/Squeeze</title>
4512 <link>http://people.skolelinux.org/pere/blog/Setting_up_a_new_school_with_Debian_Edu_Squeeze.html</link>
4513 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Setting_up_a_new_school_with_Debian_Edu_Squeeze.html</guid>
4514 <pubDate>Wed, 25 Jan 2012 21:00:00 +0100</pubDate>
4515 <description>&lt;p&gt;The next version of &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu
4516 / Skolelinux&lt;/a&gt; will include a new tool
4517 &lt;tt&gt;sitesummary2ldapdhcp&lt;/tt&gt;, which can be used to quickly set up all
4518 the computers in a school without much manual labour. Here is a short
4519 summary on how to use it to set up a new school.&lt;/p&gt;
4520
4521 &lt;p&gt;First, install a combined Main Server and Thin Client Server as the
4522 central server in the network. Next, PXE boot all the client machines
4523 as thin clients and wait 5 minutes after the last client booted to
4524 allow the clients to report their existence to the central server. When
4525 this is done, log on to the central server and run
4526 &lt;tt&gt;sitesummary2ldapdhcp -a&lt;/tt&gt; in the &lt;tt&gt;konsole&lt;/tt&gt; to use the
4527 collected information to generate system objects in LDAP. The output
4528 will look similar to this:&lt;/p&gt;
4529
4530 &lt;p&gt;&lt;blockquote&gt;&lt;pre&gt;
4531 % sitesummary2ldapdhcp -a
4532 info: Updating machine tjener.intern [10.0.2.2] id ether-00:01:02:03:04:05.
4533 info: Create GOsa machine for auto-mac-00-01-02-03-04-06 [10.0.16.20] id ether-00:01:02:03:04:06.
4534
4535 Enter password if you want to activate these changes, and ^c to abort.
4536
4537 Connecting to LDAP as cn=admin,ou=ldap-access,dc=skole,dc=skolelinux,dc=no
4538 enter password: *******
4539 %
4540 &lt;/pre&gt;&lt;/blockquote&gt;&lt;/p&gt;
4541
4542 &lt;p&gt;After providing the LDAP administrative password (the same as the
4543 root password set during installation), the LDAP database will be
4544 populated with system objects for each PXE booted machine with
4545 automatically generated names. The final step to set up the school is
4546 then to log into &lt;a href=&quot;https://oss.gonicus.de/labs/gosa/&quot;&gt;GOsa&lt;/a&gt;,
4547 the web based user, group and system administration system to change
4548 system names, add systems to the correct host groups and finally
4549 enable DHCP and DNS for the systems. All clients that should be used
4550 as diskless workstations should be added to the workstation-hosts
4551 group. After this is done, all computers can be booted again via PXE
4552 and get their assigned names and group based configuration
4553 automatically.&lt;/p&gt;
4554
4555 &lt;p&gt;We plan to release beta3 with the updated version of this feature
4556 enabled this weekend. You might want to give it a try.&lt;/p&gt;
4557
4558 &lt;p&gt;Update 2012-01-28: When calling sitesummary2ldapdhcp to add new
4559 hosts, one need to add the option -a. I forgot to mention this in my
4560 original text, and have added it to the text now.&lt;/p&gt;

4565 <title>Skolelinux-intervju: Paul Reidar Løsnesløkken</title>
4566 <link>http://people.skolelinux.org/pere/blog/Skolelinux_intervju__Paul_Reidar_L_snesl_kken.html</link>
4567 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Skolelinux_intervju__Paul_Reidar_L_snesl_kken.html</guid>
4568 <pubDate>Wed, 18 Jan 2012 14:30:00 +0100</pubDate>
4569 <description>&lt;p&gt;I serien med intervjuer av folk i
4570 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt;-miljøet, har jeg nå
4571 lyktes med å få tak i en skolemann som ikke er aktiv med utviklingen,
4572 men likevel har vært med nesten siden starten av prosjektet. Jeg
4573 ønsker derfor velkommen til Paul Reidar Løsnesløkken, en mann med
4574 mange års erfaring i bruk av Skolelinux.&lt;/p&gt;
4575
4576 &lt;p&gt;&lt;strong&gt;Hvem er du, og hva driver du med til daglig?&lt;/strong&gt;&lt;/p&gt;
4577
4578 &lt;p&gt;Jeg driftet tidligere IKT løsningen for skolene i
4579 &lt;a href=&quot;http://www.nord-odal.kommune.no/&quot;&gt;Nord-Odal&lt;/a&gt;. I dag er jeg
4580 IKT-konsulent for hele kommunen og samarbeider med
4581 &lt;a href=&quot;http://www.hedmarken-ikt.no/&quot;&gt;Hedmark-IKT&lt;/a&gt; for best mulig
4582 tjenester til kommunen. Jeg har bakgrunn som elektronikkreparatør og
4583 grunnskolelærer og har tatt en del fag innen IKT, i hovedsak
4584 driftsfag. IKT i Nord-Odal kommune blir i dag driftet av Hedmark IKT
4585 som er et samarbeid mellom Løten, Stange, Grue, Hamar, Kongsvinger og
4586 Nord-Odal. Jeg er fortsatt &quot;IKT-personen&quot; på skolene i kommunen og
4587 følger opp og gjør enkelte mindre endringer der.&lt;/p&gt;
4588
4589 &lt;p&gt;&lt;strong&gt;Hvordan kom du i kontakt med Skolelinux-prosjektet?&lt;/strong&gt;&lt;/p&gt;
4590
4591 &lt;p&gt;Kommunen satset på Skolelinux i 2004. Jeg var ikke med i
4592 beslutningsprosessen den gang, men ble likevel med fra starten når
4593 dette ble levert.&lt;/p&gt;
4594
4595 &lt;p&gt;&lt;strong&gt;Hva er fordelene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
4596
4597 &lt;p&gt;Fordelene med Skolelinux er rask oppstart, sentral drift av
4598 klientene, klienter som jobber raskt og effektivt, bedre
4599 funksjonalitet på eldre utstyr og en ganske god programpakke med fri
4600 programvare som følger med. Løsningen med halvtykke klienter gjør at
4601 prosessering skjer lokalt med alltid ferske maskiner.&lt;/p&gt;
4602
4603 &lt;p&gt;Skolelinux kan fungere godt på gammelt utstyr, men det er klart at
4604 utstyr også blir for gammelt selv for Skolelinux. I forbindelese med
4605 at vi nylig fikk nye servere og ny installasjon kastet jeg ut ca 60
4606 klienter som fortsatt var i drift etter at de var kjøpt godt brukt i
4607 2004. Noe var rundt 15 år gammelt, men var fortsatt i bruk. Noen
4608 klaget på at det nå gikk veldig tregt på en del pedagogiske nettsider
4609 med flash o.l. Det er fullt forståelig.&lt;/p&gt;
4610
4611 &lt;p&gt;Jeg fikk nylig et spørsmål fra ungdomsskolens rektor om jeg kunne
4612 legge inn &lt;a href=&quot;http://freemind.sourceforge.net/&quot;&gt;FreeMind&lt;/a&gt;, et
4613 tankekartprogram , på skolens elev-Windowsmaskiner. Lærerne hadde
4614 vært på kurs og ville ta dette i bruk. Skolen har ca halvparten av
4615 elevmaskinene på bærbare Windowsmaskiner. Da kunne jeg fortelle at
4616 dette programmet allerede lå inne på den nye Skolelinuxløsningen
4617 som nettopp var satt i drift, klart til bruk.&lt;/p&gt;
4618
4619 &lt;p&gt;Vi har de bærbare maskinene på ungdomsskolen i domene med
4620 Skolelinux. Dette fungerer også meget bra nå. Elevene får opp en
4621 midlertidig windowsprofil når de logger på. Denne profilen slettes
4622 etter at de logger av, noe som medfører rene profiler hver gang de
4623 starter opp en maskin. De må lagre i sin Skolelinprofil, noe som
4624 medfører at de får tak i sine filer uavhengig av om de starter en
4625 Windowsmaskin eller en Skolelinuxklient. Det er mye mindre trafikk i
4626 det trådløse nettet etter at ikke hele profiler blir lastet opp til de
4627 enkelte Windowsmaskinene og tilbake når man avslutter. Jeg vet ikke om
4628 dette er standardoppsett i Skolelinux, men slik er vårt oppsett
4629 nå.&lt;/p&gt;
4630
4631 &lt;p&gt;Vi har i flere år satt opp vår løsning slik at skriverkøer slettes
4632 og skrivere startes hver natt. Hyggelig å høre at dette nå skal bli
4633 en standard i Skolelinuxløsningen. Dette har vært en god hjelp for
4634 oss.&lt;/p&gt;
4635
4636 &lt;p&gt;Elevene er lite opptatt av om de jobber på en Skolelinux eller en
4637 Windowsmaskin bare de har de programmene de trenger og at det virker
4638 når det skal brukes. Vi kjører mest mulig de samme programmene på
4639 Windows som i Skolelinux, som f.eks Audacity og LibreOffice.&lt;/p&gt;
4640
4641 &lt;p&gt;&lt;strong&gt;Hva er ulempene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
4642
4643 &lt;p&gt;Lærere bruker hos oss Windows. Dette fordi de da selv har mer
4644 kontroll over sin maskin, kan bruke den overalt, og kan legge inn
4645 programmer selv når de trenger noe i forhold til kurs o.l de er
4646 på. Jeg tror lærernes selvstendighet her gjør dem tryggere på IKT-bruk
4647 generelt. Det at de av og til får opp advarsler og lignende gjør også
4648 at de må tenke igjennom og spørre om ting rundt datasikkerhet.&lt;/p&gt;
4649
4650 &lt;p&gt;Det er en del programmer vi bruker som ikke finnes for Linux. Mest
4651 brukt er nok Photostory3 som brukes i mange sammenhenger, særlig på
4652 ungdomsskolen, bl.a. til å lage herbarier (plantesamling) . Dette
4653 finnes gratis for Windows, men er ikke fri programvare. Vi er opptatt
4654 av at programmer elevene bruker på skolen også kan brukes gratis
4655 hjemme. Det er også en del programmer som brukes til spesielle elever
4656 som bare går i Windows. Det er viktig med fokus på funksjoner og ikke
4657 på hvilket OS man bruker.&lt;/p&gt;
4658
4659 &lt;p&gt;For oss er det kombinasjonen mellom Skolelinux og Windows som gir
4660 oss en god og hel løsning. Skolelinux er best der de er gode.&lt;/p&gt;
4661
4662 &lt;p&gt;&lt;strong&gt;Hvilken fri programvare bruker du til daglig?&lt;/strong&gt;&lt;/p&gt;
4663
4664 &lt;p&gt;Selv er det LibreOffice jeg bruker til daglig. Jeg bruker selv en
4665 Windowsmaskin. Jeg har benyttet en del fri programvare i forbindelse
4666 med sjekking av trafikk i nettverk, slik som Wireshark, men dette er
4667 jo ikke aktuelt for skolene. Jeg er generelt glad i programmer som
4668 fungerer på både Linux og Windows og gjerne MAC.&lt;/p&gt;
4669
4670 &lt;p&gt;&lt;strong&gt;Hvilken strategi tror du er den rette å bruke for å få
4671 skoler til å ta i bruk fri programvare?&lt;/strong&gt;&lt;/p&gt;
4672
4673 &lt;p&gt;Det er viktig at det benyttes programmer som elevene også kan ta i
4674 bruk hjemme. Det skal da være enkelt, lovlig og gratis for
4675 elevene. Da er jeg ikke lenger veldig opptatt av om det kalles &quot;fri
4676 programvare&quot;. For skolene tror jeg &quot;gratis&quot; og &quot;funksjonelt&quot; er bedre
4677 begreper enn &quot;fri&quot; i forhold til programmer. De fleste skiller nok
4678 ikke mellom &quot;fri&quot; og &quot;gratis&quot;. Det er nå svært mange elever som
4679 benytter OpenOffice eller LibreOffice som sin primære kontorpakke
4680 hjemme.&lt;/p&gt;

4685 <title>Changing the default Iceweasel start page in Debian Edu/Squeeze</title>
4686 <link>http://people.skolelinux.org/pere/blog/Changing_the_default_Iceweasel_start_page_in_Debian_Edu_Squeeze.html</link>
4687 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Changing_the_default_Iceweasel_start_page_in_Debian_Edu_Squeeze.html</guid>
4688 <pubDate>Tue, 10 Jan 2012 15:30:00 +0100</pubDate>
4689 <description>&lt;p&gt;In the Squeeze version of
4690 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu / Skolelinux&lt;/a&gt; soon
4691 to be released, users of the system will get their default browser
4692 start page set from LDAP, allowing the system administrator to point
4693 all users to the school web page by updating one setting in LDAP. In
4694 addition to setting the default start page when a machine boots, users
4695 are shown the same page as a welcome page when they log in for the
4696 first time.&lt;/p&gt;
4697
4698 &lt;p&gt;The LDAP object dc=skole,dc=skolelinux,dc=no have an attribute
4699 labeledURI with &quot;http://www/ LDAP for Debian Edu/Skolelinux&quot; as the
4700 default content. By changing this value to another URL, all users get
4701 to see the page behind this new URL.&lt;/p&gt;
4702
4703 &lt;p&gt;An easy way to update it is by using the ldapvi tool. It can be
4704 called as &quot;&lt;tt&gt;ldapvi -ZD &#39;(cn=admin)&#39;&lt;/tt&gt;&#39; to update LDAP with the
4705 new setting.&lt;/p&gt;
4706
4707 &lt;p&gt;We have written the code to adjust the default start page and show
4708 the welcome page, and I wonder if there is an easier way to do this
4709 from within Iceweasel instead.&lt;/p&gt;

4720 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu / Skolelinux&lt;/a&gt;. If
4721 you want to test a LDAP backed Kerberos server with out of the box PXE
4722 configuration for running diskless machines and installing new
4723 machines, check it out. If you need a software solution for your
4724 school, check it out too. The full announcement is

4731 <title>Fixing an hanging debian installer for Debian Edu</title>
4732 <link>http://people.skolelinux.org/pere/blog/Fixing_an_hanging_debian_installer_for_Debian_Edu.html</link>
4733 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Fixing_an_hanging_debian_installer_for_Debian_Edu.html</guid>
4734 <pubDate>Tue, 3 Jan 2012 11:25:00 +0100</pubDate>
4735 <description>&lt;p&gt;During christmas, I have been working getting the next version of
4736 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu / Skolelinux&lt;/a&gt; ready
4737 for release. The initial problem I looked at was particularly
4738 interesting.&lt;/p&gt;
4739
4740 &lt;P&gt;The installer would hang at the end when it was doing it
4741 post-installation configuration, and whatevery I did to try to find
4742 the cause and fix it always worked while I tested it, but never when I
4743 integrated it into the installer and ran the installation from
4744 scratch. I would try to restart processes, close file descriptors,
4745 remove or create files, and the installer would always unblock and
4746 wrap up its tasks.&lt;/p&gt;
4747
4748 &lt;p&gt;Eventually the cause was found. The kernel was simply running out
4749 of entropy, causing the Kerberos setup to hang waiting for more.
4750 Pressing keys was adding entropy to the kernel, and thus all my tries
4751 to fix the problem worked not because what I was typing to fix it, but
4752 because I was typing.&lt;/P&gt;
4753
4754 &lt;p&gt;The fix I implemented was to add a background process looking at
4755 the level of entropy in the kernel (by checking
4756 /proc/sys/kernel/random/entropy_avail), and if it was too small, the
4757 installer will flush the kernel file buffers and do &#39;find /&#39; to
4758 generate some disk IO. Disk IO generate entropy in the kernel, and is
4759 one of the few things that can be initated from within the system to
4760 generate entropy.&lt;/p&gt;
4761
4762 &lt;p&gt;The fix is in
4763 &lt;a href=&quot;http://wiki.debian.org/DebianEdu/Documentation/Squeeze/Installation&quot;&gt;beta1
4764 of the Debian Edu/Squeeze&lt;/a&gt; version, and we
4765 &lt;a href=&quot;http://wiki.debian.org/DebianEdu&quot;&gt;welcome more testers and
4766 developers&lt;/a&gt;. We plan to release beta2 this weekend.&lt;/p&gt;

4774 <pubDate>Sun, 11 Dec 2011 23:10:00 +0100</pubDate>
4775 <description>&lt;p&gt;Etter en lang pause er det klart for neste mann ut i min serie med
4776 intervjuer av
4777 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt;-relaterte personer.
4778
4779 Denne gangen har jeg besøk av et avtroppende styremedlem i
4780 &lt;a href=&quot;http://www.friprogramvareiskolen.no/&quot;&gt;FRISK&lt;/a&gt;, og en mann
4781 som har vært aktiv i Linux-miljøet i Bergen siden 90-tallet.&lt;/p&gt;
4782
4783 &lt;p&gt;&lt;strong&gt;Hvem er du, og hva driver du med til daglig?&lt;/strong&gt;&lt;/p&gt;
4784
4785 &lt;p&gt;Jeg heter Peter Hansteen, og jobber til daglig som seniorkonsulent
4786 i EDB ErgoGroup i Bergen. I praksis betyr det systemadministrasjon på
4787 Unix (primært Solaris, men en viss komponent av Linux). Men Solaris
4788 er for meg et relativt nytt bekjentskap, hovedplattformen min har
4789 generelt vært OpenBSD og til dels FreeBSD.&lt;/p&gt;
4790
4791 &lt;p&gt;&lt;strong&gt;Hvordan kom du i kontakt med Skolelinux-prosjektet?&lt;/strong&gt;&lt;/p&gt;
4792
4793 &lt;p&gt;Jeg husker ikke helt alle detaljene mer ;) - men jeg tror det var
4794 gjennom news-gruppen no.it.os.unix.linux.diverse, efn-listen og
4795 etterhvert også BLUG-miljøet her i Bergen. Vi hadde et par
4796 Skolelinux-sentrerte BLUG-møter for noen år siden, og det har vært et
4797 par Skolelinux-utviklersamlinger her.&lt;/p&gt;
4798
4799 &lt;p&gt;&lt;strong&gt;Hva er fordelene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
4800
4801 &lt;p&gt;Jeg bruker dessverre ikke Skolelinux daglig. Men slik jeg kjenner
4802 prosjektet har det vært i stand til å ta opp i seg det beste av fri
4803 programvare i mange kategorier, så fra et sysadmin-perspektiv ser det
4804 ut som en svært behagelig sak. For brukerne er det vel både en fordel
4805 og en ulempe at det ikke er Windows. Men vi håper at fordelene med et
4806 fritt system etterhvert vil bli åpenbare for både elever, lærekrefter
4807 og foreldre.&lt;/p&gt;
4808
4809 &lt;p&gt;&lt;strong&gt;Hva er ulempene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
4810
4811 &lt;p&gt;Vel, ulempen er vel først og fremst at andre aktører med mer
4812 kapitalmuskel har klart å etablere seg som det både lærere og foreldre
4813 føler seg trygge på, selv om det etter mitt hode ikke er noen grunn
4814 til å være spesielt trygg på de kommersielle alternativene.&lt;/p&gt;
4815
4816 &lt;p&gt;&lt;strong&gt;Hvilken fri programvare bruker du til daglig?&lt;/strong&gt;&lt;/p&gt;
4817
4818 &lt;p&gt;Når jeg får bestemme helt selv, bruker jeg kun fri programvare. Da
4819 helst med vekt på ting som kjører greit på OpenBSD. Hjemme er det
4820 OpenBSD, Ubuntu eller FreeBSD vi bruker. På skrivebordet er det en
4821 avveining mellom Gnome, KDE eller hva-det-nå-heter som er
4822 standardvalget i Ubuntu, ellers er det de kjente tingene som
4823 LibreOffice, Emacs, mplayer. På server er det selvfølgelig Apache,
4824 for overvåking både OpenNMS og Nagios (det bare ble sånn, og
4825 forskjellige siter). Jeg skriver til tider om slikt jeg holder på med
4826
4827 &lt;a href=&quot;http://bsdly.blogspot.com&quot;&gt;http://bsdly.blogspot.com&lt;/a&gt;.&lt;/p&gt;
4828
4829 &lt;p&gt;Men vi må nevne at selv vi har en Microsoft-ting som vi slår på når
4830 vi av en eller annen grunn må. Det betyr igjen vanligvis når en
4831 mobiltelefon eller en annen lukket elektronisk dings krever kontakt
4832 via en slik for å få oppdateringene sine.&lt;/p&gt;
4833
4834 &lt;p&gt;&lt;strong&gt;Hvilken strategi tror du er den rette å bruke for å få
4835 skoler til å ta i bruk fri programvare?&lt;/strong&gt;&lt;/p&gt;
4836
4837 &lt;p&gt;Hadde vi hatt det rette svaret på det spørsmålet, så hadde vi
4838 gjerne hatt Skolelinux som førstevalg på alle skoler ;)&lt;/p&gt;
4839
4840 &lt;p&gt;Men jeg tror vi må legge vekt på flere forskjellige ting. En helt
4841 sentral sak er å fokusere på fri programvare og åpne standarder som de
4842 demokratiske verdiene de faktisk er. Det har kanskje kommet litt for
4843 mye i bakgrunnen i forhold til strevet etter å lage det mest mulig
4844 &#39;brukervennlige&#39; systemet. Det er en tung vei å gå, så det er
4845 forståelig at freenix-aktivister heller velger å skrive kode og annet
4846 som er mer lystbetont. Mer praktisk tror jeg vi må gjøre i alle fall
4847 to ting: For det første sørge for å fortsette med å levere det best
4848 mulige frie produktet, slik at det er lett å både komme i gang og
4849 holde systemene i daglig drift, og for det andre 2) spore opp mulige
4850 aktivister der de finnes, via lokale brukergrupper, sosiale medier
4851 eller annet og sørge for at de fortsetter å være aktive. Mer og
4852 mindre uformelle treff kan være nyttig i tillegg til de mer
4853 organiserte møtene med foredrag, konferanser og utviklersamlinger.&lt;/p&gt;

4860 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Skolelinux_intervju__Frode_Jemtland.html</guid>
4861 <pubDate>Wed, 27 Jul 2011 08:50:00 +0200</pubDate>
4862 <description>&lt;p&gt;Neste mann ut i min serie med intervjuer av Skolelinux-relaterte
4863 personer er en tidligere styreleder i
4864 &lt;a href=&quot;http://www.friprogramvareiskolen.no/&quot;&gt;FRISK&lt;/a&gt; som var med
4865 fra starten av
4866 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt;-prosjektet.&lt;/p&gt;
4867
4868 &lt;p&gt;&lt;strong&gt;Hvem er du, og hva driver du med til daglig?&lt;/strong&gt;&lt;/p&gt;
4869
4870 &lt;p&gt;Mitt navn er Frode Jemtland, og jeg jobber i Hedmark IKT, som er et
4871 driftsselskap for Grue, Hamar, Kongsvinger, Løten, Nord-Odal og Stange
4872 kommuner. Her er jeg leder for avdelingen Løsninger og Arkitektur. Vi
4873 har i hovedansvar for servere, infrastruktur og løsninger som
4874 helhet.&lt;/p&gt;
4875
4876 &lt;p&gt;&lt;strong&gt;Hvordan kom du i kontakt med Skolelinux-prosjektet?&lt;/strong&gt;&lt;/p&gt;
4877
4878 &lt;p&gt;Jobbet i IBM fra 2000, og da spesielt med Linux. Dette var da et av
4879 de mest tydelige linux prosjektene i Norge, og her ønsket jeg å
4880 bidra. Var aktivt med i prosjektet i 4-5 år.&lt;/p&gt;
4881
4882 &lt;p&gt;&lt;strong&gt;Hva er fordelene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
4883
4884 &lt;p&gt;Fordelene slik jeg ser det er den sentraliserte driftmodellen, og
4885 alle de vel gjennomtenkte løsningene som er inkludert i denne
4886 løsningen. Samtidig er det basert på en stabil, og godt kjent
4887 plattform. Dette vil si at man har en løsning som skal være mye
4888 tilgjengelig, og hvor det er relativt enkelt å få tak i personer som
4889 kan mye om den grunnleggende plattformen.&lt;/p&gt;
4890
4891 &lt;p&gt;&lt;strong&gt;Hva er ulempene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
4892
4893 &lt;p&gt;De største utfordringene med en løsningen er at den er intensiv på f.eks
4894 nettverk. I seg selv ikke et problem for en enkelt skole, men skal løsningen
4895 kjøres i større skala, med sentraliserte servere, så gir dette noen
4896 utfordringer.&lt;/p&gt;
4897
4898 &lt;p&gt;Utifra hva jeg har sett på større installasjoner så er det ikke så
4899 enkelt å skjønne, hva som bør gjøres for at den skal skaleres opp, og
4900 da ta godt vare på alle sider av dette, ikke bare mer server å fordele
4901 last/trykk, men hvordan også beholde robustheten og fleksibiliteten i
4902 løsningen.&lt;/p&gt;
4903
4904 &lt;p&gt;En annen utfordring er at stadig flere produkter som skal brukes i
4905 skoleløsningen ikke er laget til å kunne brukes i en
4906 skolelinuxløsning. Det blir derfor fort mye skreddersøm i de
4907 forskjellige installasjonene, for å få diverse pedagogiske programmer,
4908 webløsninger, smartboards, m.m. til å fungere. Man er også en for
4909 liten kundebase til at leverandørene ønsker å gjøre noe med
4910 utfordringen. Problemet overlates til oss.&lt;/p&gt;
4911
4912 &lt;p&gt;Det er også en kontinuerlig utfordring rundt problemet med å holde
4913 programvare på stabile versjoner, kontra å få ny funksjonalitet. Dette
4914 er jo en konflikt mellom oss som ønsker å drifte en stabil, og
4915 kostnadseffektiv løsning, mot sluttbrukerne som ønsker seg funksjoner
4916 det er vant med fra andre løsninger, eller som de må ha for at et
4917 eller annet nytt produkt skal fungere i løsningen. Dette er en
4918 utfordring også for andre plattformer.&lt;/p&gt;
4919
4920 &lt;p&gt;En siste utfordring som ikke har noe med løsningen å gjøre, men med
4921 det omkringliggende miljøet denne skal kjøre i, er at de enhetene som
4922 skal drifte dataløsninger for kommuner og fylkeskommuner begynner å
4923 profesjonaliseres, og er da avhengig av å ha standard løsninger for å
4924 drifte store brukermasser. MS er selvsagt klar over dette, og har jo
4925 nå flere områder de begynner å bli veldig dominerende på. Den største,
4926 og mest problematiske er katalogtjenesten. Man får snart ikke tak i
4927 større løsninger som ikke krever en AD. Når man da har store enheter
4928 som drifter både kommunalt ansatte og skoler, så vil det være et
4929 stordriftargument å standardisere på en katalog tjeneste, og da har
4930 man ikke noe valg. Her er alle slike driftsenheter for små til å få
4931 gjort om på dette. Her burde konkurransemyndighetene kommet på
4932 banen. Men konkurransetilsynet i USA griper sjeldent (og ikke før det
4933 har gått veldig lang tid) inn i monopolsituasjoner så lenge
4934 monopolisten er et amerikansk firma, så da har vel ikke andre
4935 myndigheter så mye de skulle ha sagt....&lt;/p&gt;
4936
4937 &lt;p&gt;&lt;strong&gt;Hvilken fri programvare bruker du til daglig?&lt;/strong&gt;&lt;/p&gt;
4938
4939 &lt;p&gt;Privat kjører jeg Debian på alle mine datamaskiner. Det gjør jeg
4940 også på min jobbmaskin. Vi har også 15-20 linux servere av typene
4941 SuSE, Debian, Redhat, CentOS m.m. Jeg bruker derfor mye fri
4942 programvare. Av enkelt programmer kan sikkert masse nevnes. Hvis vi
4943 skal begrense oss til daglig, så må jeg si: OpenOffice, Firefox,
4944 Kontact, Kopete, Amarok,
4945 &lt;a href=&quot;http://gramps-project.org/&quot;&gt;Gramps&lt;/a&gt;, Kate, ssh, bash,
4946 rsync, backuppc m.m.&lt;/p&gt;
4947
4948 &lt;p&gt;&lt;strong&gt;Hvilken strategi tror du er den rette å bruke for å få
4949 skoler til å ta i bruk fri programvare?&lt;/strong&gt;&lt;/p&gt;
4950
4951 &lt;p&gt;Det er et godt spørsmål, som jeg har lurt på selv.&lt;/p&gt;
4952
4953 &lt;p&gt;Argumentene som ofte har vært brukt om at ting koster mindre holder
4954 ikke mål når man ser på hva som faktisk koster penger. Det er de
4955 ansatte som er en kostnadsdriver. Det vil si at hvis man har et system
4956 som den ansatte kan, så vil en kostnad på dette systemet kunne
4957 forsvares ganske mye ved at den ansatte gjør dette raskere og
4958 effektivt. Også uten å måtte eventuelt leie inn folk.&lt;/p&gt;
4959
4960 &lt;p&gt;Jeg syns det er viktigere å fokusere på prinsippet med å velge fri
4961 programvare, men det er også et felt hvor man fort møter lite
4962 forståelse blant de ansatte i skolen.&lt;/p&gt;
4963
4964 &lt;p&gt;Her må nok strategien fortsette å være at de sentrale myndighetene
4965 må sende tydelige signaler for hva de ønsker at offentlige enheter
4966 skal gjøre. Det var mye positivt på gang ang. dette for et par år
4967 siden. Både med eNorge og eKommune planene, men dette syns jeg har
4968 stoppet opp. En del av dette kan jo kanskje være usikkerheten som
4969 etter hvert har blitt, når man har sett kompleksiteten i de
4970 prosjektene som har blitt igangsatt. Det har også blitt noe usikkerhet
4971 i markedet ref. Sun, Oracle, Novell, Microsoft m.m. Samtidig har jo
4972 også de proprietære programleverandørene sørget for å endre sine
4973 lisenser slik at man uansett ikke slipper unna kostnaden til deres
4974 produkter, selv om man skulle velge alternativer. Da er det økonomiske
4975 argumentet, som jeg nevnte tidligere, spilt ganske godt ut over
4976 sidelinjen.&lt;/p&gt;

4984 <pubDate>Sun, 10 Apr 2011 11:00:00 +0200</pubDate>
4985 <description>&lt;p&gt;Neste mann ut er Marius Kotsbak, styremedlem i
4986 &lt;a href=&quot;http://www.friprogramvareiskolen.no/&quot;&gt;FRISK&lt;/a&gt; og mangeårig
4987 bidragsyter i
4988 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt;-prosjektet.&lt;/p&gt;
4989
4990 &lt;p&gt;&lt;strong&gt;Hvem er du, og hva driver du med til daglig?&lt;/strong&gt;&lt;/p&gt;
4991
4992 &lt;p&gt;Jeg er en systemutvikler/kybernetiker og jobber med dette til
4993 daglig. På fritiden tester jeg ut/bruker mye fri programvare, og
4994 bidrar med testing og utvikling når jeg ser stort nok behov for det og
4995 jeg har noe å bidra med.&lt;/p&gt;
4996
4997 &lt;p&gt;&lt;strong&gt;Hvordan kom du i kontakt med Skolelinux-prosjektet?&lt;/strong&gt;&lt;/p&gt;
4998
4999 &lt;p&gt;Hmm, det er lenge siden, så det er nesten så jeg ikke husker. Jeg
5000 hadde vel hørt om prosjektet i media før en gjeng i Trondheim startet
5001 opp SPIST, Skolelinux-prosjektet i Sør-Trøndelag, hvor vi hjalp noen
5002 skoler i nærområdet med å installere Skolelinux og finne brukt
5003 IT-utstyr til disse. Det var moro å gjøre noe praktisk for å spre
5004 Skolelinux, og å se hvor fort gjort det var å sette opp utrangerte
5005 klientmaskiner og få disse opp som tynnklienter på helt nye datasaler
5006 på skolene, kun med kostnaden til servere.&lt;/p&gt;
5007
5008 &lt;p&gt;&lt;strong&gt;Hva er fordelene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
5009
5010 &lt;p&gt;Det er et system spesielt skreddersydd for drift av et stort antall
5011 klienter mot servere, og da spesielt i henhold til skolers behov. Det
5012 er enkelt og billig å installere og drifte, og det trenger ikke ny
5013 maskinvare for god ytelse.&lt;/p&gt;
5014
5015 &lt;p&gt;&lt;strong&gt;Hva er ulempene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
5016
5017 &lt;p&gt;Hardwarestøtten kunne vært bedre og i enda større grad
5018 installerbart rett ut av boksen. Distribusjonen har til tider hatt
5019 litt gammel programvare pga. at den følger Debian sine utgivelser.
5020 Kanskje man skulle vurdert en versjon basert på Ubuntu eller andre
5021 distribusjoner i tillegg?&lt;/p&gt;
5022
5023 &lt;p&gt;&lt;strong&gt;Hvilken fri programvare bruker du til daglig?&lt;/strong&gt;&lt;/p&gt;
5024
5025 &lt;p&gt;Oi, det er ikke lite. Her er det jeg kommer på i farta. Jeg bruker
5026 Linux og Ubuntu, og på Ubuntu programene Firefox, Thunderbird,
5027 Chromium, Pidgin, Digikam, OpenOffice, Wireshark, git og irssi.
5028 Telefonen min er en Android, og der bruker jeg programmene K-9 Mail,
5029 OI Shopping list, Shuffle, ZXing, OI Notepad og ADW Desktop. På jobb
5030 bruker jeg JBoss, Eclipse, uCLinux for Blackfin, RCF-CPP, Qt, Maven,
5031 og boost-bibliotekene for C++.&lt;/p&gt;
5032
5033 &lt;p&gt;&lt;strong&gt;Hvilken strategi tror du er den rette å bruke for å få
5034 skoler til å ta i bruk fri programvare?&lt;/strong&gt;&lt;/p&gt;
5035
5036 &lt;p&gt;En bør fokusere på totalkostnader inkludert driftsbehov,
5037 fleksibilitet, åpenhet og ikke låsing til en leverandør framfor sparte
5038 lisenskostnader, samt programvarens kvalitet og fortrinn, og at den
5039 fritt kan brukes på et ubegrenset antall PC-er, også hjemme hos
5040 elevene. En bør også forbedre den fri programvaren ved testing,
5041 bugrapportering og kodebidrag om man kan, og ikke anbefale programvare
5042 uten at man har forsikret seg at den har tilstrekkelig kvalitet,
5043 ellers kan man lett oppnå det motsatte. Tror en bør selge inn
5044 konseptet til fylkes-/statsnivå, kanskje med bidrag til
5045 utviklingsarbeid fra disse som alle landets skoler kan få glede
5046 av.&lt;/p&gt;

5055 <description>&lt;p&gt;Mine bloggposter om Linux i skolene i Norge førte til at inspektør
5056 og ildsjel på Harestad skole tok kontakt og fortalte at de bruker
5057 Linux på sin skole, og lurte på om de kunne bidra til å gjøre
5058 fordelene kjent. Riktig nok bruker de ikke
5059 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt; på denne skolen,
5060 men jeg synes dette er en god anledning til å gjøre flere fasetter
5061 rundt Linux-økosystemet kjent, og tok et lite intervju.&lt;/p&gt;
5062
5063 &lt;p&gt;&lt;strong&gt;Hvem er du, og hva driver du med til daglig?&lt;/strong&gt;&lt;/p&gt;
5064
5065 &lt;p&gt;Mitt navn er Odin Hetland Nøsen og er en 70-modell. Jeg er bosatt i
5066 Stavanger og jobber nå på 9. året som undervisninginspektør på
5067 Harestad skole i Randaberg kommune (nabokommune til Stavanger).&lt;/p&gt;
5068
5069 &lt;p&gt;&lt;strong&gt;Hvordan kom du i kontakt med Skolelinux-prosjektet?&lt;/strong&gt;&lt;/p&gt;
5070
5071 &lt;p&gt;I 2002 begynte daværende IKT-ansvarlige og jeg et arbeid på skolen
5072 med å gå over fra Win98 til... noe annet. Vi testet en rekke
5073 forskjellige løsninger, deriblant Skolelinux, men endte opp med
5074 RedHat. Skolelinux var den gang ikke modent for det vi ville ha. Jeg
5075 har siden fulgt jevnlig med på hva skolelinux holder på med, men har
5076 hele tiden vært bedre fornøyd med vår egen &quot;standardiserte&quot; løsning på
5077 RedHat/CentOS og Fedora. Vi snuser for tiden på Ubuntu som løsning på
5078 klientsiden.&lt;/p&gt;
5079
5080 &lt;p&gt;I dag har vi på skolen vår en større linux-løsning med 400 klienter
5081 som kjører en blanding av LTSP (tynnklient) og DRBL (tykk klient uten
5082 harddisk) med en masse tjenere på serverrommet. Vi drifter hele
5083 sulamitten selv med webtjener, eposttjener, webmail, filtjenere,
5084 virtuelle tjenere osv. Og IT-ansvarlig har en 80% stilling som
5085 IT-ansvarlig - og så er han KoH-lærer i de resterende 20% :-)&lt;/p&gt;
5086
5087 &lt;p&gt;Du kan få en ide om hva vi holder på med om du går inn på
5088 &lt;a href=&quot;http://www.gnuskole.no/&quot;&gt;http://www.gnuskole.no/&lt;/a&gt;.&lt;/p&gt;
5089
5090 &lt;p&gt;For å ta brodden av frykten for at ildsjeler gjør skolen sårbar om
5091 ildsjelene falle fra, har jeg forsikret kommunen og skolesjefen i
5092 Randaberg om at det finnes godt kommersielle tjenester vi kan benytte
5093 oss av - om det skulle bli nødvendig. Vi er tre stykker i kommunen som
5094 nå har &lt;strong&gt;god&lt;/strong&gt; linux-kompetanse ift. å drifte et større
5095 system. IT-avdelingen i kommunen vil ikke ta på oss med ildtang -
5096 selv om vi nok har større IT-kompetanse mot linux enn det de selv har
5097 mot windows (de kjøper en &lt;strong&gt;masse&lt;/strong&gt; konsulenttjenester
5098 fra ErgoGroup).&lt;/p&gt;
5099
5100 &lt;p&gt;I kvantitet er Harestad og Grødem skole tilsammen et større
5101 IT-system enn resten av Randaberg kommune + Kvitsøy og Rennesøy, som
5102 kommunen også har driftsansvar for. Vi har som sagt rundt 800
5103 maskiner, mens kommunen med sitt driftsansvar har ansvar for rundt 500
5104 maskiner. Det er selvfølgelig litt forskjell i hvor kritiske
5105 tjenestene våre er, men det gir allikevel et litt rart bilde når
5106 IT-avdelingen overhode ikke er interessert i å snakke med oss om
5107 hvordan vi gjør ting :-)&lt;/p&gt;
5108
5109 &lt;p&gt;&lt;strong&gt;Hva er fordelene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
5110
5111 &lt;p&gt;Fra linux-perspektivet (ikke bare Skolelinux) er det en fordel av
5112 systemet er basert på fri programvare - og dermed fritt i ordets mange
5113 betydninger. Det er alt vi trenger: stabilt, relativt enkelt å drifte
5114 (tross alt - et større windowssystem er ikke enkelt å holde live det
5115 heller), rimelig i innkjøp og drift, og sist, men ikke minst, det er
5116 moderne for sluttbruker! Linux, i sine mange varianter,
5117 &lt;strong&gt;ser&lt;/strong&gt; nytt ut, fordi det hele tiden blir
5118 oppdatert. Derfor lever systemet opp til hvordan elever forventer at
5119 et moderne GUI skal være (i motsetning til WinXP :-).&lt;/p&gt;
5120
5121 &lt;p&gt;Vi var veldig pragmatiske da vi begynte med linux i skolen. Det var
5122 billig, det fungerte og kunne bruke alle de gamle windows-maskinene
5123 som &quot;nye&quot; tynne klienter. I dag er vi mer bevisste fri
5124 programvare-tilhengere. Vi har oppdaget hva det er - og vi liker
5125 det!&lt;/p&gt;
5126
5127 &lt;p&gt;En av de &lt;strong&gt;store&lt;/strong&gt; fordelene med fri programvare er at
5128 vi kan installere tjenester vi ønsker å tilby brukerne våre - uten å
5129 måtte tenke på om vi har råd til lisensene (fordi det er ingen). Alt
5130 vi setter i produksjon er ut i fra brukernes behov og vår kapasitet
5131 til å drifte dem. Vi skreddersyr tjenestene etter behovet og dermed
5132 trenger vi ikke ende opp med å kjøpe en pakke der vi egentlig bare var
5133 interessert i en liten del av den.&lt;/p&gt;
5134
5135 &lt;p&gt;Bruk av linux frigjør ikke økonomiske midler, fordi midlene til IKT
5136 i skole er for få i utgangspunktet - men vi får så
5137 &lt;strong&gt;mye&lt;/strong&gt; mer igjen for dem når vi bruker en linux-løsning
5138 fremfor en windows-løsning. I praksis ser vi at vi måtte ut med det
5139 dobbelte på budsjettet vårt om vi skulle hatt en tilsvarende
5140 windows-løsning, som det vi i dag drifter med linux.&lt;/p&gt;
5141
5142 &lt;p&gt;&lt;strong&gt;Hva er ulempene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
5143
5144 &lt;p&gt;Ikke all pedagogisk programvare er tilgjengelig. Det er en del
5145 programvare i skolen som er laget med utviklerverktøy som bare virker
5146 i windows, f.eks. Drillpro, LingDys/LingWrite. Det er også
5147 &quot;programmer&quot; som bare virker om du har tilgang til Microsoft Office,
5148 f.eks. AskiRaski.&lt;/p&gt;
5149
5150 &lt;p&gt;Vi sliter også litt med at video-codecer ikke alltid er like lett å
5151 få opp å gå på klientene. Det er alltid en eller annen videosnutt fra
5152 nrk.no som ikke er så samarbeidsvillig, uansett mediaplayer.&lt;/p&gt;
5153
5154 &lt;p&gt;&lt;strong&gt;Hvilken fri programvare bruker du til daglig?&lt;/strong&gt;&lt;/p&gt;
5155
5156 &lt;p&gt;Alt :-) På skolen bruker vi det som finnes og som er nyttig. Det vi
5157 bruker mest er Firefox (jobber med Chrome, fordi det er
5158 &lt;strong&gt;mye&lt;/strong&gt; raskere med Flash enn Firefox), OpenOffice (skal
5159 over til LibreOffice), GIMP osv. Standardpakken av
5160 sluttbrukerprogrammer.&lt;/p&gt;
5161
5162 &lt;p&gt;På tjenernivå bruker vi OpenWebMail (skal over til Zimbra), Exim
5163 osv.&lt;/p&gt;
5164
5165 &lt;p&gt;Personlig bruker jeg de fleste programmer over flere plattformer,
5166 men jeg har lagt meg til en vane å prioritere bruken av fri
5167 programvare også i Windows 7 og OSX.&lt;/p&gt;
5168
5169 &lt;p&gt;&lt;strong&gt;Hvilken strategi tror du er den rette å bruke for å få
5170 skoler til å ta i bruk fri programvare?&lt;/strong&gt;&lt;/p&gt;
5171
5172 &lt;p&gt;Jeg er langt i fra sikker. For det første handler det mye om at
5173 IKT-avdelingen i kommunen ofte er de som styrer hva som er IKT på
5174 skolene - og de liker å bruke avtalene med Microsoft, som de garantert
5175 har fra før. Dessuten - Select 6-avtalen til skolene gjør Microsoft
5176 skvettbillig.&lt;/p&gt;
5177
5178 &lt;p&gt;Vi la vekt på effektiv drift av systemet - og at vi kunne øke
5179 antall maskiner uten å måtte øke budsjett for utstyr eller personell
5180 særlig mye, enn om vi hadde gått for en Microsoft-løsning. I praksis
5181 ser vi at en ren linux-installasjon driftes til halve prisen av en
5182 Microsoft-løsning.&lt;/p&gt;
5183
5184 &lt;p&gt;Vi har i praksis også sett at det lærerne (og elevene) liker er at
5185 vi tilbyr &lt;strong&gt;veldig&lt;/strong&gt; mange tjenester som ikke er så
5186 vanlige i en Microsoft-løsning. Det er ikke så vanlig at
5187 &lt;strong&gt;elevene&lt;/strong&gt; også har epost, hjemmekontor osv. Det har vi
5188 også brukt som et vellykket argument mot Microsoft.&lt;/p&gt;
5189
5190 &lt;p&gt;Den beste måten er selvfølgelig at noen bare bestemmer
5191 det. Problemet er å få dem som har makt til å bestemme det til faktisk
5192 å gjøre det ;-)&lt;/p&gt;

5200 <pubDate>Sun, 27 Feb 2011 12:50:00 +0100</pubDate>
5201 <description>&lt;p&gt;En dame som har bidratt lenge til fri programvare i skoleverket og
5202 i foreningen som organiserer skolelinux-utviklersamlinger,
5203 &lt;a href=&quot;http://www.friprogramvareiskolen.no/&quot;&gt;FRISK&lt;/a&gt;, er neste
5204 intervjuoffer. Det er en glede å her presentere en lærer fra Håkvik.&lt;/p&gt;
5205
5206 &lt;p&gt;&lt;strong&gt;Hvem er du, og hva driver du med til daglig?&lt;/strong&gt;&lt;/p&gt;
5207
5208 &lt;p&gt;Jeg heter Astri Sletteng. Jeg er lærer og IKT veileder ved Håkvik
5209 skole i Narvik kommune. Min bakgrunn når det gjelder IKT: Av formell
5210 utdannelse har jeg lærerutdanning, Master i skoleledelse og IKT for
5211 lærere. Har jobba som IKT veileder siden 2002.&lt;/p&gt;
5212
5213 &lt;p&gt;Det viktigste for meg som IKT veileder er å få fundamentert den
5214 5. basisferdigheten, digital kompetanse ved skolen min på en god måte
5215 slik at hele skolesamfunnet tar i bruk IKT i alle fag. Dette arbeidet
5216 gjøres i nært samarbeid med skolens ledelse.&lt;/p&gt;
5217
5218 &lt;p&gt;Min viktigste jobb som IKT veileder er å være motivator og pådriver
5219 i IKT arbeidet ved skolen.&lt;/p&gt;
5220
5221 &lt;p&gt;&lt;strong&gt;Hvordan kom du i kontakt med Skolelinux-prosjektet?&lt;/strong&gt;&lt;/p&gt;
5222
5223 &lt;p&gt;Jobber i en kommune hvor vi satser på Fri programvare. I 2004 ble
5224 det gjort et politisk vedtak om at vi skulle innføre Skolelinux ved
5225 alle skolene i kommunen. Jeg har dermed en god del erfaring med
5226 Skolelinux, samt annen fri programvare som Open Office, Joomla, Moodle
5227 etc.&lt;/p&gt;
5228
5229 &lt;p&gt;&lt;strong&gt;Hva er fordelene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
5230
5231 &lt;p&gt;Siden vi jobber med åpen kildekode kan vi få programmene og
5232 produktene tilpasset vår bruk. Det er jo heller ikke en ulempe at
5233 skolen kommer bedre ut økonomisk, men først og fremst er det viktig
5234 for oss at vi har digitale systemer som gjør at vi kan følge
5235 læreplanen i alle fag. Det syns jeg at vi kan gjøre gjennom
5236 Skolelinux.&lt;/p&gt;
5237
5238 &lt;p&gt;&lt;strong&gt;Hva er ulempene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
5239
5240 &lt;p&gt;Skolen er avhengige av å ha folk på IT avdelinga i kommunen som kan
5241 drive support, og være tilgjengelige når vi trenger hjelp. Det er en
5242 ulempe at ikke alle på denne avdelingen nødvendigvis er god på
5243 Linux.&lt;/p&gt;
5244
5245 &lt;p&gt;Vi har også noen utfordringer når det kommer til spesielle
5246 programmer som enkelte elever er avhengige av ? og som ikke er
5247 plattform uavhengige. Her har vi i Friprog-verden, men også
5248 departement en jobb å gjøre.&lt;/p&gt;
5249
5250 &lt;p&gt;&lt;strong&gt;Hvilken fri programvare bruker du til daglig?&lt;/strong&gt;&lt;/p&gt;
5251
5252 &lt;p&gt;Skolen vår bruker Skolelinux, Open Office, Iceweazel (Mozilla),
5253 VLC, Tux paint, Scribus, FreeMind, GIMP, digiKam, Ksnapshot, GeoGebra,
5254 Moodle (innført på alle klassetrinn + som et administrativt verktøy)
5255 og Joomla som hjemmeside.&lt;p&gt;
5256
5257 &lt;p&gt;Det er de jeg kommer på i farten. I tillegg har vi Smartboard
5258 installert på server, men det regnes vel ikke som fri programvare?&lt;/p&gt;
5259
5260 &lt;p&gt;&lt;strong&gt;Hvilken strategi tror du er den rette å bruke for å få
5261 skoler til å ta i bruk fri programvare?&lt;/strong&gt;&lt;/p&gt;
5262
5263 &lt;p&gt;Først og fremst trenger skolen oppetider på sine datasystemer. Syns
5264 også at det at vi kan få tilpasset plattform og systemer til vår bruk
5265 er en god strategi å bruke.&lt;/p&gt;

5273 <pubDate>Wed, 16 Feb 2011 12:00:00 +0100</pubDate>
5274 <description>&lt;p&gt;Styret i foreningen som organiserer skolelinux-utviklersamlinger,
5275 &lt;a href=&quot;http://www.friprogramvareiskolen.no/&quot;&gt;FRISK&lt;/a&gt;, er fullt av
5276 flinke folk. Denne gangen har jeg fått et ferskt styremedlem som
5277 kommer fra Ubuntu-miljøet i tale.&lt;/p&gt;
5278
5279 &lt;p&gt;&lt;strong&gt;Hvem er du, og hva driver du med til daglig?&lt;/strong&gt;&lt;/p&gt;
5280
5281 &lt;p&gt;Rubén Romero y Cordero, 81-modell, deltidspappa (50%) for en jente
52826 år. Jobber i Oslo som Global Sales Executive hos Varnish Software
5283 og til daglig har jeg kontakt med kunder fra hele verden. Min
5284 forkjærlighet for fri programvare har gjort at jeg har nå flere års
5285 erfaring med salg av slike løsninger (bl.a. fra Redpill Linpro og
5286 Freecode) og mye innsikt og kunnskap om det globale IT-markedet.
5287 Ellers er jeg involvert i flere prosjekter bl.a. er jeg Ubuntu
5288 Community medlem, kontaktpersonen for Ubuntu Norge og driveren av
5289 SpreadUbuntu marketing prosjektet og nå fersk styremedlem i FRISK. Jeg
5290 har brukt GNU/Linux siden 1997.&lt;/p&gt;
5291
5292 &lt;p&gt;&lt;strong&gt;Hvordan kom du i kontakt med Skolelinux-prosjektet?&lt;/strong&gt;&lt;/p&gt;
5293
5294 &lt;p&gt;Som Debian bruker siden slutten av 90-tallet var det uunngåelig å
5295 ikke komme bort i Skolelinux. Dette var vel i slutten av 2001 når jeg
5296 var student ved UiO. Flere år senere fikk jeg lastet og testet Venus
5297 (Skolelinux 1.0) på release dagen.&lt;/p&gt;
5298
5299 &lt;p&gt;&lt;strong&gt;Hva er fordelene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
5300
5301 &lt;p&gt;Fri programvare bygges sten for sten i det åpne, slik at koden og
5302 prosessen den lages på kan gjennomskues av andre enn de som har laget
5303 det. Det er et vitenskapelig og gjennomsiktig måte å lage programvare
5304 på.&lt;/p&gt;
5305
5306 &lt;p&gt;Skoler i vårt samfunn skal være steder hvor vitenskapelig kunnskap
5307 deles til alle. I dag har vi ikke et vitenskapelig tilnærming til
5308 hvordan programvaren som brukes på skolen lages. Skolelinux bringer
5309 inn at slik tilnærming i skoleverkets klasserom, siden
5310 operativsystemet er en åpent platform som gir skolene muligheten til å
5311 dra nytte av programvare som er laget av tusenvis av mennesker verden
5312 rundt og som gir elevene så vel som lærerne muligheten til å bruke,
5313 dele, forandre og forbedre OSet sitt uten begrensninger. I den
5314 forbindelsen representerer Skolelinux også konkrete resultater utfra
5315 samhandling på tvers av grenser.&lt;/p&gt;
5316
5317 &lt;p&gt;Når det gjelder de tekniske fordelene av Skolelinux er jeg sikker
5318 på at andre enn meg har allerede beskrevet disse bedre enn det jeg
5319 kan. Men jeg kan likevel tilføye noe: Skolelinux som sådan er en
5320 community-drevet operativsystemplatform. Som i ethvert
5321 community-prosjekt har alle Skolelinux brukere muligheten til å
5322 påvirke retning av prosjektet og resultatet som gjenspeiles i
5323 programvaren. Dette kommer sjeldent frem og jeg mener at det er noe
5324 som burde fokuseres mer på.&lt;/p&gt;
5325
5326 &lt;p&gt;&lt;strong&gt;Hva er ulempene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
5327
5328 &lt;p&gt;De største ulempene er:&lt;/p&gt;
5329
5330 &lt;ul&gt;
5331 &lt;li&gt;Mangel på kompetanse&lt;/li&gt;
5332 &lt;li&gt;Mangel av administrative verktøy som kunne hjelpe lokale IT
5333 avdelinger å bruke Skolelinux til mer enn bare en tjener for
5334 terminalklienter. Et eksempel: Zentyal sin web-dashboard.&lt;/li&gt;
5335 &lt;/ul&gt;
5336
5337 &lt;p&gt;Bedre og mer intuitive administrative verktøy kunne løst deler av
5338 problemet, men det er unektelig at ved bruk av Skolelinux må
5339 IT-personalet vite hva de gjør for å få ting gjort riktig, eller i det
5340 hele tatt. Med andre platformer er kompetansen enklere tilgjengelig og
5341 løsningene kan fungere på en tilfredstillende, om ikke riktig
5342 måte.&lt;/p&gt;
5343
5344 &lt;p&gt;&lt;strong&gt;Hvilken fri programvare bruker du til daglig?&lt;/strong&gt;&lt;/p&gt;
5345
5346 &lt;p&gt;Har brukt GNU/Linux utelukkende sommitt skrivebord OS siden 2000. I
5347 dag bruker jeg Ubuntu og gjør det meste med friprogramvare verktøyene
5348 som er tilgjengelige der. Med over 20.000 programmer å velge mellom er
5349 dette mer enn nok for de fleste brukerne.&lt;/p&gt;
5350
5351 &lt;p&gt;&lt;strong&gt;Hvilken strategi tror du er den rette å bruke for å få
5352 skoler til å ta i bruk fri programvare?&lt;/strong&gt;&lt;/p&gt;
5353
5354 &lt;p&gt;Opplysning og pragmatikk. Vi prøver å løse problemer med bruk av
5355 programvare. De fleste utfordringene skolene har på IKT-siden kan
5356 løses ved hjelp av friprogramvareverktøy i dag. Det som trenges er
5357 opplysning, kunnskap og kompetanse.&lt;/p&gt;

5365 <pubDate>Sun, 23 Jan 2011 12:00:00 +0100</pubDate>
5366 <description>&lt;p&gt;Denne gangen er det Tromsøkontoret til Friprog-senteret, og nyvalgt
5367 styremedlem i &lt;a href=&quot;http://www.friprogramvareiskolen.no/&quot;&gt;foreningen
5368 FRISK&lt;/a&gt; jeg har fått i tale i min intervjuserie med
5369 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt;-folk.&lt;/p&gt;
5370
5371 &lt;p&gt;&lt;strong&gt;Hvem er du, og hva driver du med til daglig?&lt;/strong&gt;&lt;/p&gt;
5372
5373 &lt;p&gt;Jeg heter Morten Amundsen og jobber i
5374 &lt;a href=&quot;http://www.friprog.no/&quot;&gt;Friprog.no&lt;/a&gt;, men er for tiden leid
5375 ut til &lt;a href=&quot;http://www.bredbandsfylket.no/&quot;&gt;Bredbåndsfylket
5376 Troms&lt;/a&gt; der jeg jobber med ett prosjekt som heter
5377 &quot;&lt;a href=&quot;http://www.bredbandsfylket.no/skolefjoela.157417.no.html&quot;&gt;Skolefjøla&lt;/a&gt;&quot;
5378 Vi ser på en åpen løsning som integrerer eksisterende lukkete
5379 løsninger sammen med fri programvare. Målet er å gi elever og lærere
5380 en plattform som de kan tilpasse utfra behov.&lt;/p&gt;
5381
5382 &lt;p&gt;&lt;strong&gt;Hvordan kom du i kontakt med Skolelinux-prosjektet?&lt;/strong&gt;&lt;/p&gt;
5383
5384 &lt;p&gt;Skolelinux har jeg møtt ved flere anledninger opp gjennom åra, både gjennom
5385 entusiastiske skolelinuxbrukere og skeptiske &quot;forståsegpåere&quot; :-)&lt;/p&gt;
5386
5387 &lt;p&gt;Jeg husker en leverandør av et stort OS for noen år siden mente at
5388 Skolelinux var kun for hackere og nerder og at ingen seriøse skoler
5389 kunne ta dette i bruk. Heldigvis er kunnskapen større nå og
5390 skikkelige &quot;IT-folk&quot; søker alltid å utvide sin kunnskap.
5391
5392 &lt;p&gt;&lt;strong&gt;Hva er fordelene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
5393
5394 &lt;p&gt;Ja det er mange fordeler. Uavhengighet, stabilitet, åpenhet, standarder
5395 osv. Tror det er viktig at man ikke begrenser mulighetene på den plattformen
5396 elevene skal jobbe.&lt;/p&gt;
5397
5398 &lt;p&gt;&lt;strong&gt;Hva er ulempene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
5399
5400 &lt;p&gt;Det største hinderet er det vi opplever på andre områder rundt
5401 fri programvare, nemlig kunnskap. For mange er det trygt å velge det vi
5402 alltid har valgt. Fordi leverandørene rundt oss sitter på den kunnskapen og
5403 de vi støtter oss på har den samme. Hvis vi klarer å riste løs litt og
5404 glemme gamle kriger mellom operativsystemer og leverandører, men sette ned
5405 hva som er viktig og velge ut fra det, så hadde man kanskje kommet ut med
5406 litt andre resultat. Jeg tror IT-folk er konservative og velger tradisjonelt
5407 og det er synd.&lt;/p&gt;
5408
5409 &lt;p&gt;&lt;strong&gt;Hvilken fri programvare bruker du til daglig?&lt;/strong&gt;&lt;/p&gt;
5410
5411 &lt;p&gt;Jeg bruker Ubuntu, Android, Jolicloud, Open Office, Zimbra, Picasa
5412 og Firefox samt en bråte med tjenester som er webbasert. Det eneste
5413 som er betalingslisens for er OSX. Ser at jeg jobber mer og mer i
5414 skyen og setter pris på alt jeg slipper egen klient til. Derfor er
5415 jeg veldig sjarmert av små kjappe operativsystemer som krever minimalt
5416 av maskinvaren.&lt;/p&gt;
5417
5418 &lt;p&gt;&lt;strong&gt;Hvilken strategi tror du er den rette å bruke for å få
5419 skoler til å ta i bruk fri programvare?&lt;/strong&gt;&lt;/p&gt;
5420
5421 &lt;p&gt;Tror en blanding av krav og informasjon er veien å gå. Krav om
5422 sikkerhet, oppetid og åpne standarder. Informasjon om muligheter og
5423 alternativer. Her har leverandører, IT-avdelinger og pedagoger en vei
5424 å gå sammen. Det er til slutt LÆRING det dreier seg om, og da må man
5425 få mest mulig læring for pengene man har.&lt;/p&gt;

5433 <pubDate>Wed, 19 Jan 2011 12:00:00 +0100</pubDate>
5434 <description>&lt;p&gt;Denne gang har jeg fått tak i en mangeårig unix-mann som etter
5435 mange år ved Universitetet i Oslo, der jeg først traff ham, har
5436 flyttet tilbake til vestlandet, og der bidratt til å revitalisere
5437 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt;-oppsettet i
5438 Florø.&lt;/p&gt;
5439
5440 &lt;p&gt;&lt;strong&gt;Hvem er du, og hva driver du med til daglig?&lt;/strong&gt;&lt;/p&gt;
5441
5442 &lt;p&gt;Sturle Sunde, ansvarleg for skulenettet i Flora kommune. Eg driv,
5443 vidareutviklar og er andrelinje brukarstøtte for datanettet ved
5444 skulane i Flora kommune. 10 skular og meir enn 700 maskiner med
5445 Linux, medrekna tynnklientar. Tidlegare jobba eg i mange år med
5446 unix-drift ved Universitetets senter for informasjonsteknologi ved
5447 Universitetet i Oslo.&lt;/p&gt;
5448
5449 &lt;p&gt;&lt;strong&gt;Hvordan kom du i kontakt med Skolelinux-prosjektet?&lt;/strong&gt;&lt;/p&gt;
5450
5451 &lt;p&gt;Det er vanskeleg å svare konkret på. Eg har drive med Unix og Linux i
5452 alle år, og Skulelinux er eit godt kjent prosjekt i miljøet. Det var
5453 først i 2008, då eg tok til i min noverande jobb, at eg fekk bruk for
5454 Skulelinux for alvor.&lt;/p&gt;
5455
5456 &lt;p&gt;Jobben min skulle vere drift av eit nytt skulenett i Flora kommune,
5457 levert av eit firma eg ikkje vil reklamere for. Systemet skulle vere
5458 ferdig levert i september året før. Dette viste seg å ta mykje lenger
5459 tid, og i haustferien 2008 hadde dei endå ikkje klart å få opp ei
5460 fungerande løysing. Situasjonen var prekær for den største skulen i
5461 kommunen med meir enn 500 elevar på ungdomssteget. Skulen hadde brukt
5462 Skulelinux før, og var tilfredse med det. No hadde dei vore utan
5463 fungerande datasystem i nesten eit år. Difor fekk eg opp ein ny tenar
5464 utanfor prosjektet og installerte Skulelinux på den. Etter litt
5465 justering av konfigurasjonen med god hjelp av #skolelinux på IRC, var
5466 den nye tenaren oppe og gjekk med både tynne og halv-tjukke klientar.
5467 Autentisering gjekk mot det nye systemet, slik at elevar og lærarar
5468 framleis har same brukarnamn og passord over alt. Dette berre
5469 fungerte, og vi bestemte oss for å erstatte delar av løysinga vi
5470 skulle få levert med Skulelinux.&lt;/p&gt;
5471
5472 &lt;p&gt;Det høyrer med til historia at det nye systemet eg skulle drive frå
5473 januar 2008 endå ikkje er ferdig levert. Dei jobbar med saka, seier
5474 dei, og har von om å fullføre leveransen i løpet av 2011.&lt;/p&gt;
5475
5476 &lt;p&gt;&lt;strong&gt;Hva er fordelene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
5477
5478 &lt;p&gt;Det er veldig mange. Eg skal ta nokre få.&lt;/p&gt;
5479
5480 &lt;p&gt;Den viktigaste fordelen er at det igrunn berre er ei maskin å passe
5481 på, og det er tenaren. Med andre løysingar har ein gjerne programvare
5482 og anna som skal vedlikehaldast på kvar enkelt maskin. Med Skulelinux
5483 kan alle feil rettast og alle program oppgraderast på alle maskiner
5484 samstundes ved å gjere endringa som må til på tenaren. Eg kan sitje
5485 på kontoret og passe på alle tenarane i kommunen derifrå.&lt;/p&gt;
5486
5487 &lt;ul&gt;
5488
5489 &lt;li&gt;Tynne klientar gjer det mogleg å bruke eldre utstyr lenge, so lenge
5490 tenaren er sterk nok. Ein liten tenar med eit par halv-moderne CPUar
5491 og 2 GiB RAM held lenge for eit typisk klasserom med 30 tynnklientar,
5492 og det er lett å utvide med fleire.
5493
5494 &lt;li&gt;Halvtjukke klientar gjer det mogleg å utnytte kapasiteten i litt
5495 nyare maskiner betre, og avlaste tenaren. Ingenting vert installert
5496 lokalt på desse heller, og harddisken kan gjerne koblast frå. Gode
5497 halvtjukke klientar kan kjøpast brukt for under 1000-lappen, og det er
5498 heile kostnaden. Ingen lisensar eller anna på toppen, og det er ikkje
5499 krav til kraftigare tenar heller.
5500
5501 &lt;li&gt;Det er Linux. Vi har ikkje noko kluss med drivarar, dei berre er
5502 der. Heller ikkje med virus, dei finst i realiteten ikkje. Eller med
5503 elevar som klussar med installert programvare, for dei klarar ikkje å
5504 øydeleggje for nokon andre enn seg sjølve.
5505
5506 &lt;/ul&gt;
5507
5508 &lt;p&gt;Skulelinux er lagt opp til å vere veldig lett å installere rett ut
5509 av boksen på ein heil skule av ein interessert lærar. Det er ofte ei
5510 god løysing for skulen. Å ha nokon til stades som kjenner systemet og
5511 kan forklare enkle ting eller løyse problem der og då, er uvurderleg
5512 viktig for ein stressa lærar fem minutt før det ringer inn.&lt;/p&gt;
5513
5514 &lt;p&gt;&lt;strong&gt;Hva er ulempene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
5515
5516 &lt;p&gt;All den ferdige konfigurasjonen gjer det tungvint å tilpasse
5517 Skulelinux til eit system som skal fungere saman med mange andre
5518 installasjonar i eit felles datanett for skulane i ein kommune. Det
5519 heile er prekonfigurert for ein skule, og utviding til mange skular
5520 med eigne tenarar er ikkje berre enkelt.&lt;/p&gt;
5521
5522 &lt;p&gt;&lt;strong&gt;Hvilken fri programvare bruker du til daglig?&lt;/strong&gt;&lt;/p&gt;
5523
5524 &lt;p&gt;Eg brukar mest alle små hjelpeprogram som føl med operativsystemet,
5525 samt scriptspråket perl. Elles er Firefox/Iceweasel, Gnome-terminal
5526 og ssh i kontinuerleg bruk. Av Linux-distribusjonar brukar eg både
5527 Debian, Ubuntu, SuSE og RedHat dagleg. Eg prøvar å finne det verktyet
5528 som passar best til kvar del av jobben.&lt;/p&gt;
5529
5530 &lt;p&gt;&lt;strong&gt;Hvilken strategi tror du er den rette å bruke for å få
5531 skoler til å ta i bruk fri programvare?&lt;/strong&gt;&lt;/p&gt;
5532
5533 &lt;p&gt;Det er to målgrupper ein må sikte mot. Det eine er alle skulane som
5534 manglar eller har eit lite tilfredsstillande opplegg i dag, og ikkje
5535 har råd til å kjøpe noko nytt og blankpussa opplegg. Der er det om å
5536 gjere å gjere det enkelt for skulane å finne Skulelinux, og gjere det
5537 enkelt for dei å få hjelp til installasjon på skulen. Gjerne med
5538 lokale kontaktpersonar. Her er det dugnadsinnsats som må til, for
5539 desse skulane har ikkje råd til å betale for dette.&lt;/p&gt;
5540
5541 &lt;p&gt;Den andre og kanskje viktigare målgruppa er dei meir eller mindre
5542 profesjonelle kundane. Alle store offentlege innkjøp, inkludert
5543 innkjøp av nytt datasystem for skular, må ut på offentleg anbod.
5544 Offentlege anbod er mykje meir lukka enn dei gjev inntrykk av, og både
5545 regelboka og boka med triks for å sminke tilbodet er tjukk. Det er
5546 vanskeleg å komme inn utan eit solid salsapparat i ryggen. Kanskje
5547 Skulelinux skulle prøve aktivt å få seg eit partnarskap med eit av dei
5548 store som gjerne vil sterkare inn på den offentlege IT-marknaden?
5549 Nokon som kjenner triksa og har krefter til å ta opp kampen mot både
5550 dårlege anbod og Rudolf Blostrupmoen IT AS. Leveranse til skulane i
5551 ein kommune er ein god måte å få ein fot inn døra som leverandør til
5552 ein lukrativ kommunemarknad som kjøper alle tenester. Ta kontakt med
5553 nokon som er passeleg store og ikkje er Microsoft-partnar, og fortell:
5554 «Vi har eit ferdig produkt som du kan selje. Nei vi skal ikkje ha for
5555 det. Du kan gjerne gjere kva du vil med det, berre vi får lov til å
5556 hjelpe deg. Målgruppa er alle kommunar, og det er noko dei vil ha.
5557 Det er eit godt produkt, brukt av mange og godt likt.»&lt;/p&gt;

5564 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Skolelinux_intervju__Embrik_Kaslegard.html</guid>
5565 <pubDate>Sun, 16 Jan 2011 12:00:00 +0100</pubDate>
5566 <description>&lt;p&gt;Neste ut i min intervjuserie med folk i
5567 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinuxprosjektet&lt;/a&gt; er
5568 lærer, mangeårig bidragsyter på epostlistene og tidligere
5569 Skolelinux-administrator på en skole i Hemsedal.&lt;/p&gt;
5570
5571 &lt;p&gt;&lt;strong&gt;Hvem er du, og hva driver du med til daglig?&lt;/strong&gt;&lt;/p&gt;
5572
5573 &lt;p&gt;Embrik Kaslegard, 1964-modell, fire barn (7-20 år). Begynte som
5574 lærer i 1989 - har hatt IKT-ansvar siden første året i jobb. Har
5575 jobbet som lærer/IKT-ansvarlig uavbrutt siden 1989. Jobbet med
5576 Skolelinux fra 2004 til 2010. Nå har jeg fått ny arbeidsplass og er
5577 40% lærer og 60% IKT med Windows XP, Win2003 server og et regionalt
5578 IKT-regime som legger premissene og begrensingene for hva vi kan gjøre
5579 på skolen.&lt;/p&gt;
5580
5581 &lt;p&gt;&lt;strong&gt;Hvordan kom du i kontakt med Skolelinux-prosjektet?&lt;/strong&gt;&lt;/p&gt;
5582
5583 &lt;p&gt;Jeg leste en artikkel om en dugnadsinstallasjon av Skolelinux på en
5584 skole på Jæren et sted. Tanken om dugnad og frihet appellerte til
5585 meg. Da vi skulle bygge ny skole var det en del vi måtte spare på,
5586 fordi vi beveget oss mot en kostnadssprekk. Kabling og investering i
5587 PC-er var en av tingene vi sparte på. Derfor kjøpe vi 72 pc-er for 390
5588 pr stk. En filtjener og en applikasjonsserver.&lt;/p&gt;
5589
5590 &lt;p&gt;&lt;strong&gt;Hva er fordelene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
5591
5592 &lt;p&gt;Fordelen er at så mye er satt opp fra starten. I tillegg er det
5593 tydelig at pakka er laga for skoleverket. Brukerne har egne
5594 skrivebord, tilgang på mange gode verktøyprogrammer. Vi slipper å
5595 tenke på virus. Brukerne har ikke mulighet til å ødelegge
5596 klientoppsett, men har gode muligheter til å endre eget oppsett. Dette
5597 tror jeg er inspirerende og kjekt for mange brukere. Mappestrukturen
5598 er ferdig og det er &quot;enkelt&quot; å designe lokale mappestrukturer via
5599 skeleton. Noen av oss i skoleverket mener skolen skal være en
5600 &quot;mot-kultur&quot;. Da er Skolelinux et av valgene man kan ta. Et annet er å
5601 spise på indisk restaurant i stedet for Mc Donald&#39;s når vi er på bytur
5602 osv.. Ordene deling, frihet, dugnad osv er positive ord i
5603 skoleverket. Det er viktig at elevene blir bevisst dette.&lt;/p&gt;
5604
5605 &lt;p&gt;&lt;strong&gt;Hva er ulempene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
5606
5607 &lt;p&gt;Kompabiliteten er selvsagt et problem, selv om det er mindre nå enn
5608 før. For IKT-personer på skolene som skal drifte dette er det
5609 problematisk med kommandoer i terminalen. I tillegg er det alt for
5610 mange programmer i Skolelinux som ikke blir brukt. Jeg tror
5611 Skolelinux er tjent med å tone ned begrepet pedagogisk programvare.
5612 Slik jeg ser det finnes ikke denne kategorien programmer lengre slik
5613 de gjorde før, som frittsående programmer som installeres på en
5614 datamaskin eller på serveren. Det finnes en del spesialpedagogiske
5615 programmer, som Textpilot, LingDys, LingRight, AskiRaski, Ny i Norge
5616 osv. Men dette er programmer for enkelt-elever eller små grupper av
5617 elever. Det som bør være fokus er at alle undervisningsressurser som
5618 lages for nettet skal være nettleseruavhengig.&lt;/p&gt;
5619
5620 &lt;p&gt;&lt;strong&gt;Hvilken fri programvare bruker du til daglig?&lt;/strong&gt;&lt;/p&gt;
5621
5622 &lt;p&gt;OpenOffice bruker jeg til vanlig kontorarbeide. VLC bruker jeg som
5623 videoavspiller og av og til streaming av film. Gimp bruker jeg i
5624 undervisningen til bildemanipulering. Firefox og Chrome er mine
5625 favoritt-nettlesere. Firefox har lenge vært førstevalget mitt, nå
5626 bruker jeg mest Chrome. Opplever den som raskere og smidigere enn
5627 Firefox. Ubuntu bruker jeg som dualboot på jobb-maskinen min i
5628 tillegg til at alle PCer hjemme har en eller annen Ubuntu-distribusjon
5629 installert. Jeg bruker Clonezilla på Ubuntu 10.04 til kloning av
5630 datamaskiner på jobb. Det er selvsagt en haug andre frie programmer
5631 jeg bruker men jeg bruker dem ikke daglig. Jeg kan ramse opp:
5632 recordmydesktop, cinelerra, acidrip, soundjuicer, audacity, NX
5633 (no-machine), Kino, Rythmbox...&lt;/p&gt;
5634
5635 &lt;p&gt;&lt;strong&gt;Hvilken strategi tror du er den rette å bruke for å få
5636 skoler til å ta i bruk fri programvare?&lt;/strong&gt;&lt;/p&gt;
5637
5638 &lt;p&gt;Jeg tror oppsøkende virksomhet er den rette strategien.
5639 Ressurspersoner gjør avtaler med rådmenn, skolesjefer, rektorer. Det
5640 er slik konkurrentene gjør det. Fokuset i slike samtaler bør være
5641 kost-nytte. Dersom personer med økonomisk ansvar ser at de kan få
5642 like godt tilbud til mindre utgifter, tror jeg det er mulighet til å
5643 få innpass. Dersom de også kan få konkrete tilbud på drift i slike
5644 samtaler, vil de kanskje bli litt mer interesserte i hvor mye penger
5645 som faktisk går til IKT i skolene. Det er også viktig at vi ikke
5646 firer for mye på krav til datamaskiner. Det er flott at Skolelinux
5647 går på &quot;utrangert&quot; utstyr, men dette bør bare presenteres som et
5648 alternativ. Skolelinux-installasjoner med utrangert utstyr er ikke å
5649 foretrekke dersom man kan unngå det. Det skaper ikke entusiasme hos
5650 brukerne (elever og lærere) når de bruker gamle datamaskiner som går
5651 tregt. Det er kjempefint med skoler som har kommet seg frem til
5652 Skolelinux og fri programvare av seg selv, men de lever på nåde.
5653 Slike valg må fundamenteres hos skoleeier.&lt;/p&gt;
5654
5655 &lt;p&gt;Oppdatering 2011-01-16 22:40: Oppdatert svarene for de tre siste
5656 spørsmålene litt mer tekst fra Embrik.&lt;/p&gt;

5664 <pubDate>Wed, 12 Jan 2011 12:00:00 +0100</pubDate>
5665 <description>&lt;p&gt;Jeg fortsetter min intervjuserie med folk i
5666 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinuxprosjektet&lt;/a&gt;. Denne
5667 gang er det en av folkene som har vært med lenge og som har tatt i
5668 bruk Skolelinux på alle skolene i Narvik kommune som skal i ilden.
5669 Han er styremedlem i
5670 &lt;a href=&quot;http://www.friprogramvareiskolen.no/&quot;&gt;foreningen
5671 FRISK&lt;/a&gt;.&lt;/p&gt;
5672
5673 &lt;p&gt;&lt;strong&gt;Hvem er du, og hva driver du med til daglig?&lt;/strong&gt;&lt;/p&gt;
5674
5675 &lt;p&gt;Mitt navn er Viggo Fedreheim, og jeg er pedagogisk og teknisk
5676 IKT-veileder for alle skoler i Narvik kommune. Jeg drifter totalt 17
5677 servere basert på Skolelinux og Debian. Jeg holder i tillegg noen kurs
5678 mellom all driftingen. For tiden arbeider jeg med en sentral
5679 LDAP-tjener for alle skoleservere samt våre Moodle- og
5680 Joomla-installasjoner.&lt;/p&gt;
5681
5682 &lt;p&gt;&lt;strong&gt;Hvordan kom du i kontakt med Skolelinux-prosjektet?&lt;/strong&gt;&lt;/p&gt;
5683
5684 &lt;p&gt;Gjennom en eller annen nettavis i 2001 der var det skrevet om
5685 Skolelinux. Artikkelen ga meg lyst til å prøve ut systemet.&lt;/p&gt;
5686
5687 &lt;p&gt;Det startet i 2002 ved at jeg installerte en av de første utgavene
5688 av Skolelinux på en standard pc på Solneset skole i Tromsø. Denne var
5689 oppe fram til desember 2003 da jeg sluttet på den skolen og begynte i
5690 ny jobb i Narvik kommune.&lt;/p&gt;
5691
5692 &lt;p&gt; I Narvik kommune var det i 2004 kun 2 servere på da totalt 15
5693 skoler. Disse var Windows NT baserte. På disse to skolene var det lite
5694 med maskiner. Jobben med å få Narvik Kommune opp på akseptabelt nivå
5695 virket å være formidabel. Men med hjelp av gode kollegaer og leder
5696 skrev jeg en IKT plan for Narvik kommune som ble vedtatt av politikere
5697 i august 2004. I denne planen ble det bestemt at Narvik kommune skulle
5698 bruke Skolelinux. Her ble det også satt av midler til kabling av god
5699 infrastruktur på alle skoler samt innkjøp av nye datamaskiner. Så i
5700 dag har vi 17 servere hvorav 13 er på Skolelinux, med ca 1500 klienter
5701 basert på tynne, &quot;halvtykke&quot; og et stort antall bærbare pcer basert på
5702 Kubuntu.&lt;/p&gt;
5703
5704 &lt;p&gt;&lt;strong&gt;Hva er fordelene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
5705
5706 &lt;p&gt;Lisenskostnader, driftkostnader og hardwarekrav som er mye lavere
5707 enn for andre systemer.&lt;/p&gt;
5708
5709 &lt;p&gt;&lt;strong&gt;Hva er ulempene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
5710
5711 &lt;p&gt;Pedagogiske programvare som ikke fungerer mot Linux. En Stoooor
5712 flaskehals og som gjør at Linux kanskje ikke blir valgt andre
5713 plasser.&lt;/p&gt;
5714
5715 &lt;p&gt;Eksempler er Relemo, Lindys (lingit sine programmer), 5plus
5716 (matematikk). Disse er programmer som ikke lar seg kjøre i Linux.&lt;/p&gt;
5717
5718 &lt;p&gt; Men det ser ut for at mange leverandører går over til mer
5719 nettbaserte programmer istedet for å installere lokalt. Dette med
5720 enkelte leverandører som ikke kan levere programmer til Linux er et
5721 lite problem og over tid tror jeg at denne barrieren er borte.&lt;/p&gt;
5722
5723 &lt;p&gt;&lt;strong&gt;Hvilken fri programvare bruker du til daglig?&lt;/strong&gt;&lt;/p&gt;
5724
5725 &lt;p&gt;Kjører Kubuntu på laptoper, Debian squeeze på stasjonær
5726 kontorpc. Ut over dette arbeder jeg svært mye via konsoll mot andre
5727 servere.&lt;/p&gt;

5735 <pubDate>Sun, 9 Jan 2011 12:00:00 +0100</pubDate>
5736 <description>&lt;p&gt;Inspirert av
5737 &lt;a href=&quot;http://raphaelhertzog.com/tag/interview/&quot;&gt;intervjurunden&lt;/a&gt;
5738 som Raphael Hertzog har startet med folk i Debianprosjektet, fikk jeg
5739 lyst til å gjøre det samme med folk i
5740 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinuxprosjektet&lt;/a&gt;. Håpet
5741 er at de som til daglig bidrar til å fremme fri programvare i
5742 skoleverket og utvikler en linux-distribusjon spesiallaget for
5743 skolebruk kan bli bedre kjent og kanskje inspirere flere til å bidra
5744 til Skolelinux-prosjektet.&lt;/p&gt;
5745
5746 &lt;p&gt;Først ut er nyvalgt leder i
5747 &lt;a href=&quot;http://www.friprogramvareiskolen.no/&quot;&gt;foreningen FRISK&lt;/a&gt; som
5748 organiserer utviklingen av Skolelinux-distribusjonen. FRISK trenger
5749 alltid flere medlemmer, så
5750 &lt;a href=&quot;http://medlem.friprogramvareiskolen.no/index.php?page=signup&quot;&gt;meld
5751 deg gjerne inn&lt;/a&gt; hvis du vil støtte oss.&lt;/p&gt;
5752
5753 &lt;p&gt;&lt;strong&gt;Hvem er du, og hva driver du med til daglig?&lt;/strong&gt;&lt;/p&gt;

5755 &lt;p&gt;&lt;!-- Mitt navn er Arnt Ove Gregersen, jeg er en småbarnfar på 32 år som
5756 for tiden bor Trondheim. --&gt;
5757 Mitt navn er Arnt Ove Gregersen, jeg er 32 år og bor for tiden i Trondheim.
5758
5759 Her jobber jeg som systemutvikler i et firma
5760 som heter &lt;a href=&quot;http://www.geomatikk-ikt.no/&quot;&gt;Geomatikk IKT AS&lt;/a&gt;,
5761 hvor jeg er på et Vegmeldings-prosjekt for Statens Vegvesen. På
5762 fritiden er jeg styreleder i FRISK (Fri programvare i skolen) og
5763 bidrar til bl.a. Skolelinux-prosjektet når jeg får tid til det. Det er
5764 primært hjemmesiden til Skolelinux-prosjektet og
5765 &lt;a href=&quot;http://linuxveiviseren.no/&quot;&gt;Linux-veiviseren&lt;/a&gt; jeg har
5766 jobbet med her, men jeg har også gjort en del arbeid i forhold til
5767 FRISK sin hjemmeside.&lt;/p&gt;
5768
5769 &lt;p&gt;&lt;strong&gt;Hvordan kom du i kontakt med Skolelinux-prosjektet?&lt;/strong&gt;&lt;/p&gt;
5770
5771 &lt;p&gt;Jeg var på en presentasjon av prosjektet i regi av Knut Yrvin på
5772 Gløshaugen i Trondheim, hvor jeg fattet stor interesse for prosjektet
5773 og ville hjelpe til så godt jeg kunne. Dette var vel i 2002 eller
5774 2003.&lt;/p&gt;
5775
5776 &lt;p&gt;Jeg hadde fra før hørt om prosjektet fra før og syntes tanken bak var
5777 ganske fin, men hadde ikke noen interesse av bruke min egen fritid på
5778 det selv.&lt;/p&gt;
5779
5780 &lt;p&gt;I etterkant av presentasjonen startet jeg og noen andre fra
5781 Trondheim &quot;Skolelinux-prosjektet i Sør-Trøndelag&quot; . Hvor vi var med å
5782 bidra til at Trondheim kommune satte igang Selsbakk ungdomskole som et
5783 pilotprosjekt med Skolelinux, som egentlig var og er en stor suksess,
5784 men det virker ut som det ikke skjer noe mer på. I tillegg var vi med
5785 på dugnad på Brundalen videregående skole hvor vi installerte
5786 Skolelinux som såvidt jeg vet fortsatt kjører på Skolelinux.&lt;/p&gt;
5787
5788 &lt;p&gt;&lt;strong&gt;Hva er fordelene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
5789
5790 &lt;p&gt;Det bygger på fri programvare og har lav kostnad i forhold til
5791 nytteverdien. Dette fordi det har forholdsvis lav inngangsum og bruker
5792 en arkitektur med sentral-drift som gir mange driftfordeler. I
5793 tillegg vil det kunne frigjøre kostnader for skolene slik at de kan
5794 bruke dem til å ansette f,eks flere lærere om det er ønskelig.&lt;/p&gt;
5795
5796 &lt;p&gt;&lt;strong&gt;Hva er ulempene med Skolelinux slik du ser det?&lt;/strong&gt;&lt;/p&gt;
5797
5798 &lt;P&gt;Ikke all pedagogisk programvare er tilgjengelig der, som f.eks
5799 Drillpro om jeg ikke husker feil.&lt;/p&gt;
5800
5801 &lt;p&gt;&lt;strong&gt;Hvilken fri programvare bruker du til daglig?&lt;/strong&gt;&lt;/p&gt;
5802
5803 &lt;p&gt;Til utvikling av Java-applikasjoner og Android bruker jeg Eclipse og
5804 Quanta til web-utvikling via php. For all bildebehandling bruker jeg
5805 GIMP og Blender til 3d-modellering . Dessverre har Blender en bratt
5806 læringskurve i starten, men det er absolutt verdt det.
5807
5808 &lt;p&gt;Til musikk bruker jeg stort Rhytmbox. Firefox til surfing på nettet og
5809 Thunderbird og Evolution til e-post,
5810
5811 &lt;p&gt;På database-siden bruker jeg PostgreSQL, Postgis og av og til Mysql.
5812
5813 &lt;p&gt;Når jeg får tid til å spille bruker jeg som regel et strategi-spill
5814 som er basert på TA Spring-motoren (springrts.com), her er det et
5815 veldig bra utvalg av gratis spill som er av høy kvalitet. Veldig lett
5816 å bli hektet :)&lt;/p&gt;

5824 <pubDate>Tue, 4 Jan 2011 07:50:00 +0100</pubDate>
5825 <description>&lt;p&gt;Følgende inspirerende historie fant jeg i
5826 &lt;a href=&quot;http://www.digi.no/php/ny_debatt.php?id=858869#innlegg_770926&quot;&gt;kommentarfeltet
5827 hos digi.no&lt;/a&gt; i forbindelse med en trist sak om hvordan
5828 &lt;a href=&quot;http://www.digi.no/858869/datakaos-etter-linux-satsing&quot;&gt;skolen
5829 i Hemsedal har fått ødelagt&lt;/a&gt; sin Skolelinux-installasjon. Jeg har
5830 fikset endel åpenbare skrivefeil for lesbarhetens skyld.&lt;/p&gt;
5831
5832 &lt;blockquote&gt;
5833 &lt;p&gt;&lt;strong&gt;Lignende situasjon i annen kommune, se bare her:&lt;/strong&gt;
5834 &lt;br&gt;av Inspektør Siri (gjest)
5835
5836 &lt;p&gt;Kommunen min har to omtrent jevnstore tettsteder, og en
5837 ungdomsskole i hvert av tettstedene. Den minste av disse har ca 300
5838 elever og til denne sogner det 3 barneskoler. Den største har ca 350
5839 elever og til denne sogner det 4 barneskoler.&lt;/p&gt;
5840
5841 &lt;ul&gt;
5842
5843 &lt;li&gt;Kommunen har i veldig lang tid forsømt IKT i skolen, og det har
5844 bare blitt gitt smuler i ny og ne. Det er kun den største av
5845 ungdomsskolene som har hatt en skikkelig datapark, og dette takket
5846 være en naturfaglærer som ble lei av å vente på kommunen. Det gjorde
5847 at vi bestemte oss for å ta ting i egne hender, og da vha
5848 skolelinux. En testinstallasjon med 10 gamle PCer ble gjort, og vi så
5849 raskt at dette var veldig lovende. Neste etappe var å gi alle lærere
5850 egen PC på arbeidsplassene sine (2004), og så sette opp 16 PCer på to
5851 datarom. Vi har kun basert oss på å kjøpe inn brukte maskiner, og
5852 aldri dyrere enn 1000 kr pr klient. For to år siden så hadde vi
5853 klienter i alle klasserom, og totalt hadde vi da rundt 250 stk. Rundt
5854 40 klienter brukes av lærerne og kjører på en egen server. Elvene har
5855 resten, og kjører også en egen server. Servere har vi også kjøpt
5856 brukt, 2 år gamle servere koster 6-7000 kroner.&lt;/li&gt;
5857
5858 &lt;li&gt;Skolen vår er et relativt gammelt bygg, men en meget dyktig
5859 vaktmester har sammen med IKT-ansvarlig/Naturfaglærer lagt kabler til alle
5860 rom. Gradvis har vi byttet ut billige svitsjer med mer solide saker
5861 som er mulig å fjernstyre.&lt;/li&gt;
5862
5863 &lt;li&gt;Vi har i all hovedsak greid å få dette til over eget budsjett, men
5864 vi har også passet på å få penger når de andre skolene har fått
5865 bærbare PCer til lærere osv.&lt;/li&gt;
5866
5867 &lt;li&gt;Vår IKT-ansvarlig har gjort (og gjør) en fenomenal jobb, og vi har
5868 en maskinpark som de andre av kommunens skoler bare kan drømme
5869 om.&lt;/li&gt;
5870
5871 &lt;/ul&gt;
5872
5873 &lt;p&gt;Så skjer det som ofte skjer. Det kommer en eller annen
5874 selger/blåruss og skal fikse ALT. I vårt tilfelle betyr dette også
5875 sentralisering av drift. Den ny-ansatte på kommunens IT-avdelingen
5876 skal også ha jobb, og ser for seg å ta over skoledriften. Kommunen
5877 kjøper inn eksterne driftstjenester, og nekter i samme slengen å ta
5878 hensyn til skolen vår. Dette til tross for at vi alene har like mange
5879 datamaskiner som de andre til sammen. &lt;/p&gt;
5880
5881 &lt;ul&gt;
5882
5883 &lt;li&gt;Det blir krevd at vi skal innlemmes i de kommunale systemet, og
5884 det er VI som får ansvar for at dette kommer på plass. Og det er her
5885 de horrible tingene begynner å skje. &lt;/li&gt;
5886
5887 &lt;li&gt;Det settes opp en lukket Exchange server som gjør av vi ikke kan
5888 hente epost for våre ansatte. Og det kreves at vi finner løsning på
5889 dette.&lt;/li&gt;
5890
5891 &lt;li&gt;Det velges sak arkivsystem som vi pålegges å bruke, noe som gjør
5892 at vi må bruke en terminalløsning mot kommunal server. Ikke i seg selv
5893 et problem i følge IKT-ansvarlig hos oss. Men kommunens IT-avd nektet
5894 faktisk å åpne de porter OSV som vi måtte bruke.&lt;/li&gt;
5895
5896 &lt;li&gt;Vi blir pålagt å flytte på innsiden av det kommunale
5897 nettverket. Dette gjorde at vi mistet hjemmekontor for lærere og
5898 elever. Å få åpnet porter i kommunal brannmur var ikke
5899 aktuelt. Mulighet for fjerndrift ble også vekk i samme slengen. &lt;/li&gt;
5900
5901 &lt;li&gt;Vår LMS Moodle er ikke mulig å nå for elevene og lærerne.
5902
5903 &lt;/ul&gt;
5904
5905 &lt;p&gt;Den andre ungdomsskolen i kommunen begynner så å kreve at de skal
5906 få bedre datatetthet, og komme opp på et nivå som ligner det vi
5907 har. De ser at vi kan avholde eksamen hvor alle 10. klassingene får
5908 sitte ved hver sin PC. Og de har fått tilbakemelding (klager) fra VGS
5909 om manglende datakompetanse på elevene som kommer fra dem. Dette fører
5910 videre til at kommunen endelig innser at de må ta grep. &lt;/p&gt;
5911
5912 &lt;p&gt;Grepet betyr sentralisering, og farvel til vår plattform får vi
5913 høre. Det blir gjort en rekke bestemmelser og vedtak som vi ikke får
5914 være en del av. Det blir helt klart at vi må redusere antall maskiner,
5915 og det skal satses på bærbare maskiner. Siden vi ikke har fått tatt
5916 del i prosessene som angår oss, så bruker vi fagforening. Vi har ikke
5917 blitt hørt i forbindelse med endringer som er betydelig for vår
5918 hverdag, og greier å stoppe omlegging. I tillegg så har vi et politisk
5919 vedtak i kommunen på at vi skal kjøre Linux på elevnett, og dette
5920 vedtaket kan ikke administrasjonen i kommunene helt uten videre
5921 tilsidesette. &lt;/p&gt;
5922
5923 &lt;p&gt;I sum har dette gjort at vi har fått jobbe videre i fred. Og en del
5924 runder i kommunens kontrollutvalg har gjort det tydelig at vi har blitt
5925 systematisk motarbeidet. &lt;/p&gt;
5926
5927 &lt;p&gt;I dag har de andre skolene fått sine bærbare maskiner til elever og
5928 lærere, men etter 2 år med innkjøring er det fremdeles problemer
5929 her. &lt;/p&gt;
5930
5931 &lt;ul&gt;
5932
5933 &lt;li&gt;Ungdomsskolen med windows kan ikke kjøre eksamen med sine bærbare,
5934 det er for mye arbeid å renske disse for innhold slik at juks ikke er
5935 mulig.&lt;/li&gt;
5936
5937 &lt;li&gt;Utskrift er et mareritt, etter sigende pga at utskrift først
5938 sendes til sentral server, og så sendes ut til rett skriver. I snitt
5939 så tar det 7-8 minutter før utskrift starter på enkelte av
5940 skolene.&lt;/li&gt;
5941
5942 &lt;li&gt;Trådløst skaper store problemer, og det er i perioder helt umulig
5943 å komme seg på nett. Og lagring på felles server er bare å glemme i
5944 perioder.&lt;/li&gt;
5945
5946 &lt;/ul&gt;
5947
5948 &lt;p&gt;Vi har slitt mye, kranglet og sloss. Ikke med tekniske problemer,
5949 men med omgivelsene rundt som vil oss til livs. Men det har vært verdt
5950 hver dråpe med svette, og timer med irritasjon. Men vi har begynt å få
5951 rutine her nå. &lt;/p&gt;
5952
5953 &lt;ul&gt;
5954
5955 &lt;li&gt;Vi har fremdeles et system som vi styrer helt selv. &lt;/li&gt;
5956 &lt;li&gt;Vi har vist at argumentet med at vår IKT-ansvarlig kan finne seg annen jobb ikke holder mål. Vi har kjøpt driftskonto hos et firma i tilfelle krise, og vi har kjørt opplæring på flere av de yngre lærerne. &lt;/li&gt;
5957 &lt;li&gt;Vi har til enhver tid en lærling IKT driftsfag, og velger selvsagt ut dem som satser på Linux. Vi har nå begynt å få tilbake av våre tidligere elever som vil til oss nettopp fordi vi har Linux.&lt;/li&gt;
5958 &lt;li&gt;Vi har vist at vi greier å opprettholde en dobbelt så stor datapark som naboskolen, og det til en billigere penge. &lt;/li&gt;
5959 &lt;li&gt;Vi har datastøtte og support på huset, ALLTID tilgjengelig. De andre skolene må vente flere dager hvis det ikke er noe kritisk. &lt;/li&gt;
5960 &lt;li&gt;Vår IKT-ansvarlig har 50% stilling som lærer og 50% som IKT-ansvarlig. &lt;/li&gt;
5961 &lt;li&gt;Vi har en lærer på hvert trinn som har 3 timer i uka til å drive support/støtte til de andre lærerne. &lt;/li&gt;
5962 &lt;li&gt;Vi opplever at de yngste lærerne ved den andre ungdomsskolen ønsker seg over til oss. &lt;/li&gt;
5963
5964 &lt;/ul&gt;
5965
5966 &lt;p&gt;Vi skal i løpet av året starte prosess med å planlegge ny skole, og vi har fått gjennomslag for at jeg (inspektør) og IKT-ansvarlig skal ha det fulle og hele ansvar for IKT/Infrastruktur. Begrunnelsen vår som ble avgjørende her, var at IT-avd i kommunen ikke kan noe om data i skolen. &lt;/p&gt;
5967
5968 &lt;p&gt;Beklager hvis dette ble litt usammenhengende, men det ble tastet i
5969 fei, og jeg har ikke lest gjennom&lt;/p&gt;
5970 &lt;/blockquote&gt;
5971
5972 &lt;p&gt;Det kom raskt et lite svar:&lt;/p&gt;
5973
5974 &lt;blockquote&gt;
5975 &lt;p&gt;&lt;strong&gt;SV: Lignende situasjon i annen kommune, se bare her:&lt;/strong&gt;
5976 &lt;br&gt;av captain_obvious&lt;/p&gt;
5977
5978 &lt;p&gt;Inspirerende å lese. Har dere gjort noe for å fortelle denne
5979 historien videre?&lt;/p&gt;
5980
5981 &lt;p&gt;Hadde vært svært interessant om dere tok kontakt med dokument 2 eller
5982 lignende for å fortelle hvordan det egentlig står til med
5983 IT-satsningen i kommune-Norge. Om ikke annet kan du begynner med å
5984 raffinere innlegget ditt og få en gjesteartikkel på digi.no&lt;/p&gt;
5985 &lt;/blockquote&gt;
5986
5987 &lt;p&gt;Og deretter en lengre oppfølging.&lt;/p&gt;
5988
5989 &lt;blockquote&gt;
5990 &lt;p&gt;&lt;strong&gt;SV: Lignende situasjon i annen kommune, se bare her:&lt;/strong&gt;
5991 &lt;br&gt;av Inspektør Siri (gjest)
5992
5993 &lt;p&gt;Joda, vi har lekt med tanken, og vi har t.o.m skrevet flere lengre
5994 leserinnlegg myntet på aviser. Disse er ikke sendt til aviser, men
5995 brukt internt i forbindelse med møter med kommune. Vår IKT-ansvarlig
5996 har også truet med å si opp jobben sin hvis det ikke ble tatt hensyn i
5997 større grad enn hva som har vært tilfelle. VI kan også dokumentere
5998 flere brudd på anbudsregler, og vi kjenner til at relativt store
5999 IT-leverandører som ikke har fått tatt del i disse anbudene, rett og
6000 slett ikke tør melde fra av redsel for å få et dårlig rykte. &lt;/p&gt;
6001
6002 &lt;p&gt;Alt ser ut til å roe seg ned, og vi har fått opp øynene på
6003 politikerne. I sum gjør dette at vi ikke ønsker for mye publisitet nå,
6004 det vil bare rote til igjen. &lt;/p&gt;
6005
6006 &lt;p&gt;Jeg glemte å nevne at vi nå nesten ikke bruker tid på å drifte
6007 systemet vårt, noe som gjør at det aller meste av tid blir brukt til å
6008 støtte lærerne og elevene. F.eks så bruker vår IKT-ansvarlig den
6009 første timen på jobb, 0730-0830 kun til å gå ute på arbeidsplassene
6010 til læreren. Dette for å kunne svare på små og store problem, gi tips
6011 og råd, eller bare for å plukke opp hva som er behovet ute i
6012 undervisningsarealene. Det er dessverre ikke slik at alle lærerne har
6013 nok digital kompetanse til å kunne formulere alle spørsmålene de har,
6014 men ved å kunne få vise eller lufte tanker med IKT-ansvarlig så er det
6015 utrolig hva som kommer fram. &lt;/p&gt;
6016
6017 &lt;ul&gt;
6018
6019 &lt;li&gt;Jeg ser at mange bruker økonomi som argument i forhold til å bruke
6020 SkoleLinux, og jeg skal ikke legge skjul på at det var dette som i
6021 utgangspunktet var årsaken til vårt valg. Men diskusjonene og kampen
6022 med kommunens IT-avdeling har gjort at vi har fått et noe annet
6023 fokus. Fordelene med drift og stabilitet, gjør at vi ville ha valgt
6024 samme løsning selv om den var dyrere. At vi slipper langt billigere
6025 unna, som følge av 0,- lisenskostnader og lave maskinvarekostnader, er
6026 bare en bonus. &lt;/li&gt;
6027
6028 &lt;li&gt;Etter å ha kranglet oss til å få skikkelig oversikt over hva de
6029 andre skolene i kommunen bruker på IT, så har vi fått gehør for å få
6030 samme midler til innkjøp. Dette har gjort at vi nå kan kjøpe inn
6031 utstyr som de andre skolene bare kan se langt etter. Vi har nettopp
6032 kjøpt inn 3 videokamera i semiproff-klassen for å kunne lage film,
6033 samt sende live fra skoleteater/konserter. Vi har kjøpt inn digitale
6034 kompaktkamera til alle klassene. Vi har et team av lærere som skal i
6035 gang med å teste ut tablets på svake elever. Håpet et at teknologien
6036 kan være med på å gi noen av elevene litt mer motivasjon. Vi har kjøpt
6037 inn et halvt klassesett med pulsklokker, noe som har vist seg å være
6038 overraskende inspirerende for en del av elevene. Vi har også oss på
6039 fag på en høyskole litt lengre sør for oss, slik at 3 av oss nå skal
6040 ta faget &quot;Linux tjenestedrift&quot;. Som inspektør og en del av skolens
6041 administrasjon er det veldig praktisk å kunne trå til hvis det
6042 kniper. Men IKT-ansvarlig har vært UTROLIG flink til å lage rene
6043 smørbrødlister for hvordan de mest vanlige driftsproblem løses, så det
6044 er lett for flere av oss å ta del i den daglige driften. Vi har svært
6045 stor nytte av lærling (som også hjelper to av naboskolene), men det er
6046 nesten blitt slik at det er om å gjøre å komme til først for å få løse
6047 problem. Det å få fingrene på problem og utfordringer er den aller
6048 beste læremester. &lt;/li&gt;
6049
6050 &lt;/ul&gt;
6051
6052 &lt;p&gt;Når vi nå tar til med planlegging av ny skole, så vil det være med
6053 tanke på at det skal være mulig med datautstyr på alle plasser. Vi
6054 kommer i all hovedsak til å legge kabel til alle tenkelige og
6055 utenkelige plasser. WiFi koster tilnærmet NULL å sette opp i
6056 ettertid.&lt;/p&gt;
6057
6058 &lt;p&gt;Vi har ikke vært noe flink til å bidra til SkoleLinux-prosjektet,
6059 vi har rett og slett vært for opptatt med vår egen kamp. Vi har hentet
6060 mye inspirasjon fra diskusjoner som har gått i det miljøet, og vi
6061 håper at vi nå framover kan få tid til å bidra. Vi er i ferd med å
6062 bytte ut en av serverne våre, og da vil denne trolig bli satt opp som
6063 testserver for neste versjon av Skolelinux. På den måten vil vi i alle
6064 fall kunne gi tilbakemeldinger og rapportere feil. I tillegg så vil
6065 det kanskje gi oss noen nye utfordringer, for som lærlingen vår sier:
6066 &quot;Skolelinux er noe herk, det skjer jo ikke noe galt og hvordan skal
6067 jeg da lære?&quot;&lt;/p&gt;
6068
6069 &lt;/blockquote&gt;
6070
6071 &lt;p&gt;Det er veldig hyggelig å høre at
6072 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt; fungerer så bra i
6073 skoleverdagen etter å ha jobbet med det i 10 år.&lt;/p&gt;

6078 <title>How to test if a laptop is working with Linux</title>
6079 <link>http://people.skolelinux.org/pere/blog/How_to_test_if_a_laptop_is_working_with_Linux.html</link>
6080 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/How_to_test_if_a_laptop_is_working_with_Linux.html</guid>
6081 <pubDate>Wed, 22 Dec 2010 14:55:00 +0100</pubDate>
6082 <description>&lt;p&gt;The last few days I have spent at work here at the &lt;a
6083 href=&quot;http://www.uio.no/&quot;&gt;University of Oslo&lt;/a&gt; testing if the new
6084 batch of computers will work with Linux. Every year for the last few
6085 years the university have organised shared bid of a few thousand
6086 computers, and this year HP won the bid. Two different desktops and
6087 five different laptops are on the list this year. We in the UNIX
6088 group want to know which one of these computers work well with RHEL
6089 and Ubuntu, the two Linux distributions we currently handle at the
6090 university.&lt;/p&gt;
6091
6092 &lt;p&gt;My test method is simple, and I share it here to get feedback and
6093 perhaps inspire others to test hardware as well. To test, I PXE
6094 install the OS version of choice, and log in as my normal user and run
6095 a few applications and plug in selected pieces of hardware. When
6096 something fail, I make a note about this in the test matrix and move
6097 on. If I have some spare time I try to report the bug to the OS
6098 vendor, but as I only have the machines for a short time, I rarely
6099 have the time to do this for all the problems I find.&lt;/p&gt;
6100
6101 &lt;p&gt;Anyway, to get to the point of this post. Here is the simple tests
6102 I perform on a new model.&lt;/p&gt;
6103
6104 &lt;ul&gt;
6105
6106 &lt;li&gt;Is PXE installation working? I&#39;m testing with RHEL6, Ubuntu Lucid
6107 and Ubuntu Maverik at the moment. If I feel like it, I also test with
6108 RHEL5 and Debian Edu/Squeeze.&lt;/li&gt;
6109
6110 &lt;li&gt;Is X.org working? If the graphical login screen show up after
6111 installation, X.org is working.&lt;/li&gt;
6112
6113 &lt;li&gt;Is hardware accelerated OpenGL working? Running glxgears (in
6114 package mesa-utils on Ubuntu) and writing down the frames per second
6115 reported by the program.&lt;/li&gt;
6116
6117 &lt;li&gt;Is sound working? With Gnome and KDE, a sound is played when
6118 logging in, and if I can hear this the test is successful. If there
6119 are several audio exits on the machine, I try them all and check if
6120 the Gnome/KDE audio mixer can control where to send the sound. I
6121 normally test this by playing
6122 &lt;a href=&quot;http://www.nuug.no/aktiviteter/20101012-chef/ &quot;&gt;a HTML5
6123 video&lt;/a&gt; in Firefox/Iceweasel.&lt;/li&gt;
6124
6125 &lt;li&gt;Is the USB subsystem working? I test this by plugging in a USB
6126 memory stick and see if Gnome/KDE notices this.&lt;/li&gt;
6127
6128 &lt;li&gt;Is the CD/DVD player working? I test this by inserting any CD/DVD
6129 I have lying around, and see if Gnome/KDE notices this.&lt;/li&gt;
6130
6131 &lt;li&gt;Is any built in camera working? Test using cheese, and see if a
6132 picture from the v4l device show up.&lt;/li&gt;
6133
6134 &lt;li&gt;Is bluetooth working? Use the Gnome/KDE browsing tool to see if
6135 any bluetooth devices are discovered. In my office, I normally see a
6136 few.&lt;/li&gt;
6137
6138 &lt;li&gt;For laptops, is the SD or Compaq Flash reader working. I have
6139 memory modules lying around, and stick them in and see if Gnome/KDE
6140 notice this.&lt;/li&gt;
6141
6142 &lt;li&gt;For laptops, is suspend/hibernate working? I&#39;m testing if the
6143 special button work, and if the laptop continue to work after
6144 resume.&lt;/li&gt;
6145
6146 &lt;li&gt;For laptops, is the extra buttons working, like audio level,
6147 adjusting background light, switching on/off external video output,
6148 switching on/off wifi, bluetooth, etc? The set of buttons differ from
6149 laptop to laptop, so I just write down which are working and which are
6150 not.&lt;/li&gt;
6151
6152 &lt;li&gt;Some laptops have smart card readers, finger print readers,
6153 acceleration sensors etc. I rarely test these, as I do not know how
6154 to quickly test if they are working or not, so I only document their
6155 existence.&lt;/li&gt;
6156
6157 &lt;/ul&gt;
6158
6159 &lt;p&gt;By now I suspect you are really curious what the test results are
6160 for the HP machines I am testing. I&#39;m not done yet, so I will report
6161 the test results later. For now I can report that HP 8100 Elite work
6162 fine, and hibernation fail with HP EliteBook 8440p on Ubuntu Lucid,
6163 and audio fail on RHEL6. Ubuntu Maverik worked with 8440p. As you
6164 can see, I have most machines left to test. One interesting
6165 observation is that Ubuntu Lucid has almost twice the frame rate than
6166 RHEL6 with glxgears. No idea why.&lt;/p&gt;

6177 gathering&lt;/a&gt; in a long time take place here in Oslo, Norway. I
6178 really look forward to seeing all the good people working on the
6179 Squeeze release. The gathering is open for everyone interested in
6180 learning more about Debian Edu / Skolelinux.&lt;/p&gt;
6181
6182 &lt;p&gt;On Saturday, the Norwegian member organization taking care of
6183 organizing these development gatherings, Fri Programvare i Skolen,
6184 will hold its
6185 &lt;a href=&quot;http://friprogramvareiskolen.no/Genfors/2010&quot;&gt;General Assembly
6186 for 2010&lt;/a&gt;. Membership is open for all, and currently there are 388
6187 people registered as members. Last year 32 members cast their vote in
6188 the memberdb based election system. I hope more people find time to
6189 vote this year.&lt;/p&gt;

6194 <title>Why isn&#39;t Debian Edu using VLC?</title>
6195 <link>http://people.skolelinux.org/pere/blog/Why_isn_t_Debian_Edu_using_VLC_.html</link>
6196 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Why_isn_t_Debian_Edu_using_VLC_.html</guid>
6197 <pubDate>Sat, 27 Nov 2010 11:30:00 +0100</pubDate>
6198 <description>&lt;p&gt;In the latest issue of Linux Journal, the readers choices were
6199 presented, and the winner among the multimedia player were VLC.
6200 Personally, I like VLC, and it is my player of choice when I first try
6201 to play a video file or stream. Only if VLC fail will I drag out
6202 gmplayer to see if it can do better. The reason is mostly the failure
6203 model and trust. When VLC fail, it normally pop up a error message
6204 reporting the problem. When mplayer fail, it normally segfault or
6205 just hangs. The latter failure mode drain my trust in the program.&lt;p&gt;
6206
6207 &lt;p&gt;But even if VLC is my player of choice, we have choosen to use
6208 mplayer in &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian
6209 Edu/Skolelinux&lt;/a&gt;. The reason is simple. We need a good browser
6210 plugin to play web videos seamlessly, and the VLC browser plugin is
6211 not very good. For example, it lack in-line control buttons, so there
6212 is no way for the user to pause the video. Also, when I
6213 &lt;a href=&quot;http://wiki.debian.org/DebianEdu/BrowserMultimedia&quot;&gt;last
6214 tested the browser plugins&lt;/a&gt; available in Debian, the VLC plugin
6215 failed on several video pages where mplayer based plugins worked. If
6216 the browser plugin for VLC was as good as the gecko-mediaplayer
6217 package (which uses mplayer), we would switch.&lt;/P&gt;
6218
6219 &lt;p&gt;While VLC is a good player, its user interface is slightly
6220 annoying. The most annoying feature is its inconsistent use of
6221 keyboard shortcuts. When the player is in full screen mode, its
6222 shortcuts are different from when it is playing the video in a window.
6223 For example, space only work as pause when in full screen mode. I
6224 wish it had consisten shortcuts and that space also would work when in
6225 window mode. Another nice shortcut in gmplayer is [enter] to restart
6226 the current video. It is very nice when playing short videos from the
6227 web and want to restart it when new people arrive to have a look at
6228 what is going on.&lt;/p&gt;

6233 <title>Lenny-&gt;Squeeze upgrades of the Gnome and KDE desktop, now with apt-get autoremove</title>

6237 <description>&lt;p&gt;Michael Biebl suggested to me on IRC, that I changed my automated
6238 upgrade testing of the
6239 &lt;a href=&quot;http://people.skolelinux.org/~pere/debian-upgrade-testing/&quot;&gt;Lenny
6240 Gnome and KDE Desktop&lt;/a&gt; to do &lt;tt&gt;apt-get autoremove&lt;/tt&gt; when using apt-get.
6241 This seem like a very good idea, so I adjusted by test scripts and
6242 can now present the updated result from today:&lt;/p&gt;

6678 <title>Migrating Xen virtual machines using LVM to KVM using disk images</title>

6681 <pubDate>Mon, 22 Nov 2010 11:20:00 +0100</pubDate>
6682 <description>&lt;p&gt;Most of the computers in use by the
6683 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu/Skolelinux project&lt;/a&gt;
6684 are virtual machines. And they have been Xen machines running on a
6685 fairly old IBM eserver xseries 345 machine, and we wanted to migrate
6686 them to KVM on a newer Dell PowerEdge 2950 host machine. This was a
6687 bit harder that it could have been, because we set up the Xen virtual
6688 machines to get the virtual partitions from LVM, which as far as I
6689 know is not supported by KVM. So to migrate, we had to convert
6690 several LVM logical volumes to partitions on a virtual disk file.&lt;/p&gt;
6691
6692 &lt;p&gt;I found
6693 &lt;a href=&quot;http://searchnetworking.techtarget.com.au/articles/35011-Six-steps-for-migrating-Xen-virtual-machines-to-KVM&quot;&gt;a
6694 nice recipe&lt;/a&gt; to do this, and wrote the following script to do the
6695 migration. It uses qemu-img from the qemu package to make the disk
6696 image, parted to partition it, losetup and kpartx to present the disk
6697 image partions as devices, and dd to copy the data. I NFS mounted the
6698 new servers storage area on the old server to do the migration.&lt;/p&gt;

6747 &lt;p&gt;The script is perhaps so simple that it is not copyrightable, but
6748 if it is, it is licenced using GPL v2 or later at your discretion.&lt;/p&gt;
6749
6750 &lt;p&gt;After doing this, I booted a Debian CD in rescue mode in KVM with
6751 the new disk image attached, installed grub-pc and linux-image-686 and
6752 set up grub to boot from the disk image. After this, the KVM machines
6753 seem to work just fine.&lt;/p&gt;

6762 <description>&lt;p&gt;I&#39;m still running upgrade testing of the
6763 &lt;a href=&quot;http://people.skolelinux.org/~pere/debian-upgrade-testing/&quot;&gt;Lenny
6764 Gnome and KDE Desktop&lt;/a&gt;, but have not had time to spend on reporting the
6765 status. Here is a short update based on a test I ran 20101118.&lt;/p&gt;
6766
6767 &lt;p&gt;I still do not know what a correct migration should look like, so I
6768 report any differences between apt and aptitude and hope someone else
6769 can see if anything should be changed.&lt;/p&gt;

6983 <description>&lt;p&gt;Answering
6984 &lt;a href=&quot;http://www.listware.net/201011/gnash-dev/67431-gnash-dev-buildbot-looking-for-slaves.html&quot;&gt;the
6985 call from the Gnash project&lt;/a&gt; for
6986 &lt;a href=&quot;http://www.gnashdev.org:8010&quot;&gt;buildbot&lt;/a&gt; slaves to test the
6987 current source, I have set up a virtual KVM machine on the Debian
6988 Edu/Skolelinux virtualization host to test the git source on
6989 Debian/Squeeze. I hope this can help the developers in getting new
6990 releases out more often.&lt;/p&gt;
6991
6992 &lt;p&gt;As the developers want less main-stream build platforms tested to,
6993 I have considered setting up a &lt;a
6994 href=&quot;http://www.debian.org/ports/kfreebsd-gnu/&quot;&gt;Debian/kfreebsd&lt;/a&gt;
6995 machine as well. I have also considered using the kfreebsd
6996 architecture in Debian as a file server in NUUG to get access to the 5
6997 TB zfs volume we currently use to store DV video. Because of this, I
6998 finally got around to do a test installation of Debian/Squeeze with
6999 kfreebsd. Installation went fairly smooth, thought I noticed some
7000 visual glitches in the cdebconf dialogs (black cursor left on the
7001 screen at random locations). Have not gotten very far with the
7002 testing. Noticed cfdisk did not work, but fdisk did so it was not a
7003 fatal problem. Have to spend some more time on it to see if it is
7004 useful as a file server for NUUG. Will try to find time to set up a
7005 gnash buildbot slave on the Debian Edu/Skolelinux this weekend.&lt;/p&gt;

7014 <description>&lt;p&gt;Prioritising packages for the Debian Edu /
7015 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt; DVD, which is
7016 supposed provide a school with all the services and user applications
7017 needed on the pupils computer network has always been hard. Even
7018 schools without Internet connections should be able to get Debian Edu
7019 working using this DVD.&lt;/p&gt;
7020
7021 &lt;p&gt;The job became a lot harder when apt and aptitude started
7022 installing recommended packages by default. We want the same set of
7023 packages to be installed when using the DVD and the netinst CD, and
7024 that means all recommended packages need to be on the DVD. I created
7025 a patch for debian-cd in &lt;a href=&quot;http://bugs.debian.org/601203&quot;&gt;BTS
7026 report #601203&lt;/a&gt; to do this, and since this change was applied to
7027 the Debian Edu DVD build, we have been seriously short on space.&lt;/p&gt;
7028
7029 &lt;p&gt;A few days ago we decided to drop blender, wxmaxima and kicad from
7030 the default installation to save space on the DVD, believing that
7031 those needing these applications are few and can get them from the
7032 Debian archive.&lt;/p&gt;
7033
7034 &lt;p&gt;Yesterday, I had a look what source packages to see which packages
7035 were using most space. A few large packages are well know;
7036 openoffice.org, openclipart and fluid-soundfont. But I also
7037 discovered that lilypond used 106 MiB and fglrx-driver used 53 MiB.
7038 The lilypond package is pulled in as a dependency for rosegarden, and
7039 when looking a bit closer I discovered that 99 MiB of the 106 MiB were
7040 the documentation package, which is recommended by the binary package.
7041 I decided to drop this documentation package from our DVD, as most of
7042 our users will use the GUI front-ends and do not need the lilypond
7043 documentation. Similarly, I dropped the non-free fglrx-driver package
7044 which might be installed by d-i when its hardware is detected, as the
7045 free X driver should work.&lt;/p&gt;
7046
7047 &lt;p&gt;With this change, we finally got space for the LXDE and Gnome
7048 desktop packages as well as the language specific packages making the
7049 DVD more useful again.&lt;/p&gt;

7058 <description>&lt;p&gt;Some updates.&lt;/p&gt;
7059
7060 &lt;p&gt;My &lt;a href=&quot;http://pledgebank.com/gnash-avm2&quot;&gt;gnash pledge&lt;/a&gt; to
7061 raise money for the project is going well. The lower limit of 10
7062 signers was reached in 24 hours, and so far 13 people have signed it.
7063 More signers and more funding is most welcome, and I am really curious
7064 how far we can get before the time limit of December 24 is reached.
7065 :)&lt;/p&gt;
7066
7067 &lt;p&gt;On the #gnash IRC channel on irc.freenode.net, I was just tipped
7068 about what appear to be a great code coverage tool capable of
7069 generating code coverage stats without any changes to the source code.
7070 It is called
7071 &lt;a href=&quot;http://simonkagstrom.github.com/kcov/index.html&quot;&gt;kcov&lt;/a&gt;,
7072 and can be used using &lt;tt&gt;kcov &amp;lt;directory&amp;gt; &amp;lt;binary&amp;gt;&lt;/tt&gt;.
7073 It is missing in Debian, but the git source built just fine in Squeeze
7074 after I installed libelf-dev, libdwarf-dev, pkg-config and
7075 libglib2.0-dev. Failed to build in Lenny, but suspect that is
7076 solvable. I hope kcov make it into Debian soon.&lt;/p&gt;
7077
7078 &lt;p&gt;Finally found time to wrap up the release notes for &lt;a
7079 href=&quot;http://lists.debian.org/debian-edu-announce/2010/10/msg00002.html&quot;&gt;a
7080 new alpha release of Debian Edu&lt;/a&gt;, and just published the second
7081 alpha test release of the Squeeze based Debian Edu /
7082 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt;
7083 release. Give it a try if you need a complete linux solution for your
7084 school, including central infrastructure server, workstations, thin
7085 client servers and diskless workstations. A nice touch added
7086 yesterday is RDP support on the thin client servers, for windows
7087 clients to get a Linux desktop on request.&lt;/p&gt;

7092 <title>Some notes on Flash in Debian and Debian Edu</title>
7093 <link>http://people.skolelinux.org/pere/blog/Some_notes_on_Flash_in_Debian_and_Debian_Edu.html</link>
7094 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Some_notes_on_Flash_in_Debian_and_Debian_Edu.html</guid>
7095 <pubDate>Sat, 4 Sep 2010 10:10:00 +0200</pubDate>
7096 <description>&lt;p&gt;In the &lt;a href=&quot;http://popcon.debian.org/unknown/by_vote&quot;&gt;Debian
7097 popularity-contest numbers&lt;/a&gt;, the adobe-flashplugin package the
7098 second most popular used package that is missing in Debian. The sixth
7099 most popular is flashplayer-mozilla. This is a clear indication that
7100 working flash is important for Debian users. Around 10 percent of the
7101 users submitting data to popcon.debian.org have this package
7102 installed.&lt;/p&gt;
7103
7104 &lt;p&gt;In the report written by Lars Risan in August 2008
7105&lt;a href=&quot;http://wiki.skolelinux.no/Dokumentasjon/Rapporter?action=AttachFile&amp;do=view&amp;target=Skolelinux_i_bruk_rapport_1.0.pdf&quot;&gt;Skolelinux
7106 i bruk – Rapport for Hurum kommune, Universitetet i Agder og
7107 stiftelsen SLX Debian Labs&lt;/a&gt;»), one of the most important problems
7108 schools experienced with &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian
7109 Edu/Skolelinux&lt;/a&gt; was the lack of working Flash. A lot of educational
7110 web sites require Flash to work, and lacking working Flash support in
7111 the web browser and the problems with installing it was perceived as a
7112 good reason to stay with Windows.&lt;/p&gt;
7113
7114 &lt;p&gt;I once saw a funny and sad comment in a web forum, where Linux was
7115 said to be the retarded cousin that did not really understand
7116 everything you told him but could work fairly well. This was a
7117 comment regarding the problems Linux have with proprietary formats and
7118 non-standard web pages, and is sad because it exposes a fairly common
7119 understanding of whose fault it is if web pages that only work in for
7120 example Internet Explorer 6 fail to work on Firefox, and funny because
7121 it explain very well how annoying it is for users when Linux
7122 distributions do not work with the documents they receive or the web
7123 pages they want to visit.&lt;/p&gt;
7124
7125 &lt;p&gt;This is part of the reason why I believe it is important for Debian
7126 and Debian Edu to have a well working Flash implementation in the
7127 distribution, to get at least popular sites as Youtube and Google
7128 Video to working out of the box. For Squeeze, Debian have the chance
7129 to include the latest version of Gnash that will make this happen, as
7130 the new release 0.8.8 was published a few weeks ago and is resting in
7131 unstable. The new version work with more sites that version 0.8.7.
7132 The Gnash maintainers have asked for a freeze exception, but the
7133 release team have not had time to reply to it yet. I hope they agree
7134 with me that Flash is important for the Debian desktop users, and thus
7135 accept the new package into Squeeze.&lt;/p&gt;

7142 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Broken_hard_link_handling_with_sshfs.html</guid>
7143 <pubDate>Mon, 30 Aug 2010 19:30:00 +0200</pubDate>
7144 <description>&lt;p&gt;Just got an email from Tobias Gruetzmacher as a followup on my
7145 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/Broken_umask_handling_with_sshfs.html&quot;&gt;previous
7146 post about sshfs&lt;/a&gt;. He reported another problem with sshfs. It
7147 fail to handle hard links properly. A simple way to spot this is to
7148 look at the . and .. entries in the directory tree. These should have
7149 a link count &gt;1, but on sshfs the count is 1. I just tested to see
7150 what happen when trying to hardlink, and this fail as well:&lt;/p&gt;
7151
7152 &lt;pre&gt;
7153 % ln foo bar
7154 ln: creating hard link `bar&#39; =&gt; `foo&#39;: Function not implemented
7155 %
7156 &lt;/pre&gt;
7157
7158 &lt;p&gt;I have not yet found time to implement a test for this in my file
7159 system test code, but believe having working hard links is useful to
7160 avoid surprised unix programs. Not as useful as working file locking
7161 and symlinks, which are required to get a working desktop, but useful
7162 nevertheless. :)&lt;/p&gt;
7163
7164 &lt;p&gt;The latest version of the file system test code is available via
7165 git from
7166 &lt;a href=&quot;http://github.com/gebi/fs-test&quot;&gt;http://github.com/gebi/fs-test&lt;/a&gt;&lt;/p&gt;

7173 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Skolelinux_i_Osloskolen.html</guid>
7174 <pubDate>Thu, 26 Aug 2010 22:25:00 +0200</pubDate>
7175 <description>&lt;p&gt;Denne høsten skal endelig alle Osloskolene få mulighet til å bruke
7176 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt;. Ny IT-løsning
7177 har vært rullet ut i noen måneder nå, og så vidt jeg fikk vite før
7178 sommeren skulle alle skoler ha nytt opplegg på plass før oppstart nå i
7179 høst. På alle skolene skal en kunne velge ved installasjon om en skal
7180 ha Windows eller Skolelinux på maskinene, og en kan i tillegg
7181 PXE-boote maskinene over nett som tynne klienter eller diskløse
7182 arbeidsstasjoner. Jeg er spent på hvor mange skoler som velger å ta i
7183 bruk Skolelinux, og gleder meg til å se hvordan dette utvikler seg.
7184 Løsningen leveres av
7185 &lt;a href=&quot;http://www.logica.no/&quot;&gt;Logica&lt;/a&gt; med
7186 &lt;a href=&quot;http://www.slxdrift.no/&quot;&gt;Skolelinux Drift AS&lt;/a&gt; som
7187 underleverandør, og jeg har vært involvert i utviklingen av løsningen
7188 via Skolelinux Drift AS siden prosjektet starter. Jeg synes det er
7189 fantastisk at Skolelinux er kommet så langt siden vi startet i 2001 at
7190 alle elevene i Osloskolene nå skal få mulighet til å bruke
7191 løsningen. Jeg håper de vil sette pris på alle de
7192 &lt;a href=&quot;http://www.skolelinux.no/linux-signpost/&quot;&gt;fantastiske
7193 brukerprogrammene&lt;/a&gt; som er tilgjengelig i Skolelinux.&lt;/p&gt;

7198 <title>Broken umask handling with sshfs</title>
7199 <link>http://people.skolelinux.org/pere/blog/Broken_umask_handling_with_sshfs.html</link>
7200 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Broken_umask_handling_with_sshfs.html</guid>
7201 <pubDate>Thu, 26 Aug 2010 13:30:00 +0200</pubDate>
7202 <description>&lt;p&gt;My file system sematics program
7203 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/Testing_if_a_file_system_can_be_used_for_home_directories___.html&quot;&gt;presented
7204 a few days ago&lt;/a&gt; is very useful to verify that a file system can
7205 work as a unix home directory,and today I had to extend it a bit. I&#39;m
7206 looking into alternatives for home directory access here at the
7207 University of Oslo, and one of the options is sshfs. My friend
7208 Finn-Arne mentioned a while back that they had used sshfs with Debian
7209 Edu, but stopped because of problems. I asked today what the problems
7210 where, and he mentioned that sshfs failed to handle umask properly.
7211 Trying to detect the problem I wrote this addition to my fs testing
7212 script:&lt;/p&gt;
7213
7214 &lt;pre&gt;
7215 mode_t touch_get_mode(const char *name, mode_t mode) {
7216 mode_t retval = 0;
7217 int fd = open(name, O_RDWR|O_CREAT|O_LARGEFILE, mode);
7218 if (-1 != fd) {
7219 unlink(name);
7220 struct stat statbuf;
7221 if (-1 != fstat(fd, &amp;statbuf)) {
7222 retval = statbuf.st_mode &amp; 0x1ff;
7223 }
7224 close(fd);
7225 }
7226 return retval;
7227 }
7228
7229 /* Try to detect problem discovered using sshfs */
7230 int test_umask(void) {
7231 printf(&quot;info: testing umask effect on file creation\n&quot;);
7232
7233 mode_t orig_umask = umask(000);
7234 mode_t newmode;
7235 if (0666 != (newmode = touch_get_mode(&quot;foobar&quot;, 0666))) {
7236 printf(&quot; error: Wrong file mode %o when creating using mode 666 and umask 000\n&quot;,
7237 newmode);
7238 }
7239 umask(007);
7240 if (0660 != (newmode = touch_get_mode(&quot;foobar&quot;, 0666))) {
7241 printf(&quot; error: Wrong file mode %o when creating using mode 666 and umask 007\n&quot;,
7242 newmode);
7243 }
7244
7245 umask (orig_umask);
7246 return 0;
7247 }
7248
7249 int main(int argc, char **argv) {
7250 [...]
7251 test_umask();
7252 return 0;
7253 }
7254 &lt;/pre&gt;
7255
7256 &lt;p&gt;Sure enough. On NFS to a netapp, I get this result:&lt;/p&gt;
7257
7258 &lt;pre&gt;
7259 Testing POSIX/Unix sematics on file system
7260 info: testing symlink creation
7261 info: testing subdirectory creation
7262 info: testing fcntl locking

7268 Unlocking 2 byte from 1073741824
7269 info: testing umask effect on file creation
7270 &lt;/pre&gt;
7271
7272 &lt;p&gt;When mounting the same directory using sshfs, I get this
7273 result:&lt;/p&gt;
7274
7275 &lt;pre&gt;
7276 Testing POSIX/Unix sematics on file system
7277 info: testing symlink creation
7278 info: testing subdirectory creation
7279 info: testing fcntl locking
7280 Read-locking 1 byte from 1073741824
7281 Read-locking 510 byte from 1073741826
7282 Unlocking 1 byte from 1073741824
7283 Write-locking 1 byte from 1073741824
7284 Write-locking 510 byte from 1073741826
7285 Unlocking 2 byte from 1073741824
7286 info: testing umask effect on file creation
7287 error: Wrong file mode 644 when creating using mode 666 and umask 000
7288 error: Wrong file mode 640 when creating using mode 666 and umask 007
7289 &lt;/pre&gt;
7290
7291 &lt;p&gt;So, I can conclude that sshfs is better than smb to a Netapp or a
7292 Windows server, but not good enough to be used as a home
7293 directory.&lt;/p&gt;
7294
7295 &lt;p&gt;Update 2010-08-26: Reported the issue in
7296 &lt;a href=&quot;http://bugs.debian.org/594498&quot;&gt;BTS report #594498&lt;/a&gt;&lt;/p&gt;
7297
7298 &lt;p&gt;Update 2010-08-27: Michael Gebetsroither report that he found the
7299 script so useful that he created a GIT repository and stored it in
7300 &lt;a href=&quot;http://github.com/gebi/fs-test&quot;&gt;http://github.com/gebi/fs-test&lt;/a&gt;.&lt;/p&gt;

7305 <title>No hardcoded config on Debian Edu clients</title>
7306 <link>http://people.skolelinux.org/pere/blog/No_hardcoded_config_on_Debian_Edu_clients.html</link>
7307 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/No_hardcoded_config_on_Debian_Edu_clients.html</guid>
7308 <pubDate>Mon, 9 Aug 2010 20:15:00 +0200</pubDate>
7309 <description>&lt;p&gt;As reported earlier, the last few days I have looked at how Debian
7310 Edu clients are configured, and tried to get rid of all hardcoded
7311 configuration settings on the clients. I believe the work to be
7312 mostly done, and the clients seem to work just fine with dynamically
7313 generated configuration.&lt;/p&gt;
7314
7315 &lt;p&gt;What is the point, you might ask? The point is to allow a Debian
7316 Edu desktop to integrate into an existing network infrastructure
7317 without any manual configuration.&lt;/p&gt;
7318
7319 &lt;p&gt;This is what happens when installing a Debian Edu client here at
7320 the University of Oslo using PXE. With the PXE installation, I am
7321 asked for language (Norwegian Bokmål), locality (Norway) and keyboard
7322 layout (no-latin1), Debian Edu profile (Roaming Workstation), if I
7323 accept to reformat the hard drive (yes), if I want to submit info to
7324 popcon.debian.org (no) and root password (secret). After answering
7325 these questions, the installer goes ahead and does its thing, and
7326 after around 50 minutes it is done. I press enter to finish the
7327 installation, and the machine reboots into KDE. When the machine is
7328 ready and kdm asks for login information, I enter my university
7329 username and password, am told by kdm that a local home directory has
7330 been created and that I must log in again, and finally log in with the
7331 same username and password to the KDE 4.4 desktop. At no point during
7332 this process did it ask for university specific settings, and all the
7333 required configuration was dynamically detected using information
7334 fetched via DHCP and DNS. The roaming workstation is now ready for
7335 use.&lt;/p&gt;
7336
7337 &lt;p&gt;How was this done, you might wonder? First of all, here is the
7338 list of things that need to be configured on the client to get it
7339 working properly out of the box:&lt;/p&gt;
7340
7341 &lt;ul&gt;
7342 &lt;li&gt;IP address/netmask and DNS server.&lt;/li&gt;
7343 &lt;li&gt;Web proxy URL.&lt;/li&gt;
7344 &lt;li&gt;LDAP server for NSS directory information (user, group, etc).&lt;/li&gt;
7345 &lt;li&gt;Kerberos server for PAM password checking.&lt;/li&gt;
7346 &lt;li&gt;SMB mount point to access the network home directory. (*)&lt;/li&gt;
7347 &lt;li&gt;Central syslog server to send syslog messages to. (*)&lt;/li&gt;
7348 &lt;li&gt;Sitesummary collector URL to submit info to central server. (*)&lt;/li&gt;
7349 &lt;/ul&gt;
7350
7351 &lt;p&gt;(Hm, did I forget anything? Let me knew if I did.)&lt;/p&gt;
7352
7353 &lt;p&gt;The points marked (*) are not required to be able to use the
7354 machine, but needed to provide central storage and allowing system
7355 administrators to track their machines. Since yesterday, everything
7356 but the sitesummary collector URL is dynamically discovered at boot
7357 and installation time in the svn version of Debian Edu.&lt;/p&gt;
7358
7359 &lt;p&gt;The IP and DNS setup is fetched during boot using DHCP as usual.
7360 When a DHCP update arrives, the proxy setup is updated by looking for
7361 http://wpat/wpad.dat and using the content of this WPAD file to
7362 configure the http and ftp proxy in /etc/environment and
7363 /etc/apt/apt.conf. I decided to update the proxy setup using a DHCP
7364 hook to ensure that the client stops using the Debian Edu proxy when
7365 it is moved outside the Debian Edu network, and instead uses any local
7366 proxy present on the new network when it moves around.&lt;/p&gt;
7367
7368 &lt;p&gt;The DNS names of the LDAP, Kerberos and syslog server and related
7369 configuration are generated using DNS information at boot. First the
7370 installer looks for a host named ldap in the current DNS domain. If
7371 not found, it looks for _ldap._tcp SRV records in DNS instead. If an
7372 LDAP server is found, its root DSE entry is requested and the
7373 attributes namingContexts and defaultNamingContext are used to
7374 determine which LDAP base to use for NSS. If there are several
7375 namingContexts attibutes and the defaultNamingContext is present, that
7376 LDAP subtree is used as the base. If defaultNamingContext is missing,
7377 the subtrees listed as namingContexts are searched in sequence for any
7378 object with class posixAccount or posixGroup, and the first one with
7379 such an object is used as the LDAP base. For Kerberos, a similar
7380 search is done by first looking for a host named kerberos, and then
7381 for the _kerberos._tcp SRV record. I&#39;ve been unable to find a way to
7382 look up the Kerberos realm, so for this the upper case string of the
7383 current DNS domain is used.&lt;/p&gt;
7384
7385 &lt;p&gt;For the syslog server, the hosts syslog and loghost are searched
7386 for, and the _syslog._udp SRV record is consulted if no such host is
7387 found. This algorithm works for both Debian Edu and the University of
7388 Oslo. A similar strategy would work for locating the sitesummary
7389 server, but have not been implemented yet. I decided to fetch and
7390 save these settings during installation, to make sure moving to a
7391 different network does not change the set of users being allowed to
7392 log in nor the passwords required to log in. Usernames and passwords
7393 will be cached by sssd when the user logs in on the Debian Edu
7394 network, and will not change as the laptop move around. For a
7395 non-roaming machine, there is no caching, but given that it is
7396 supposed to stay in place it should not matter much. Perhaps we
7397 should switch those to use sssd too?&lt;/p&gt;
7398
7399 &lt;p&gt;The user&#39;s SMB mount point for the network home directory is
7400 located when the user logs in for the first time. The LDAP server is
7401 consulted to look for the user&#39;s LDAP object and the sambaHomePath
7402 attribute is used if found. If it isn&#39;t found, the home directory
7403 path fetched from NSS is used instead. Assuming the path is of the
7404 form /site/server/directory/username, the second part is looked up in
7405 DNS and used to generate a SMB URL of the form
7406 smb://server.domain/username. This algorithm works for both Debian
7407 edu and the University of Oslo. Perhaps there are better attributes
7408 to use or a better algorithm that works for more sites, but this will
7409 do for now. :)&lt;/p&gt;
7410
7411 &lt;p&gt;This work should make it easier to integrate the Debian Edu clients
7412 into any LDAP/Kerberos infrastructure, and make the current setup even
7413 more flexible than before. I suspect it will also work for thin
7414 client servers, allowing one to easily set up LTSP and hook it into a
7415 existing network infrastructure, but I have not had time to test this
7416 yet.&lt;/p&gt;
7417
7418 &lt;p&gt;If you want to help out with implementing these things for Debian
7419 Edu, please contact us on debian-edu@lists.debian.org.&lt;/p&gt;
7420
7421 &lt;p&gt;Update 2010-08-09: Simon Farnsworth gave me a heads-up on how to
7422 detect Kerberos realm from DNS, by looking for _kerberos TXT entries
7423 before falling back to the upper case DNS domain name. Will have to
7424 implement it for Debian Edu. :)&lt;/p&gt;

7433 <description>&lt;p&gt;A few years ago, I was involved in a project planning to use
7434 Windows file servers as home directory servers for Debian
7435 Edu/Skolelinux machines. This was thought to be no problem, as the
7436 access would be through the SMB network file system protocol, and we
7437 knew other sites used SMB with unix and samba as the file server to
7438 mount home directories without any problems. But, after months of
7439 struggling, we had to conclude that our goal was impossible.&lt;/p&gt;
7440
7441 &lt;p&gt;The reason is simply that while SMB can be used for home
7442 directories when the file server is Samba running on Unix, this only
7443 work because of Samba have some extensions and the fact that the
7444 underlying file system is a unix file system. When using a Windows
7445 file server, the underlying file system do not have POSIX semantics,
7446 and several programs will fail if the users home directory where they
7447 want to store their configuration lack POSIX semantics.&lt;/p&gt;
7448
7449 &lt;p&gt;As part of this work, I wrote a small C program I want to share
7450 with you all, to replicate a few of the problematic applications (like
7451 OpenOffice.org and GCompris) and see if the file system was working as
7452 it should. If you find yourself in spooky file system land, it might
7453 help you find your way out again. This is the fs-test.c source:&lt;/p&gt;

7640
7641 &lt;p&gt;I do not remember the exact details of the problems we saw, but one
7642 of them was with locking, where if I remember correctly, POSIX allow a
7643 read-only lock to be upgraded to a read-write lock without unlocking
7644 the read-only lock (while Windows do not). Another was a bug in the
7645 CIFS/SMB client implementation in the Linux kernel where directory
7646 meta information would be wrong for a fraction of a second, making
7647 OpenOffice.org fail to create its deep directory tree because it was
7648 not allowed to create files in its freshly created directory.&lt;/p&gt;
7649
7650 &lt;p&gt;Anyway, here is a nice tool for your tool box, might you never need
7651 it. :)&lt;/p&gt;
7652
7653 &lt;p&gt;Update 2010-08-27: Michael Gebetsroither report that he found the
7654 script so useful that he created a GIT repository and stored it in
7655 &lt;a href=&quot;http://github.com/gebi/fs-test&quot;&gt;http://github.com/gebi/fs-test&lt;/a&gt;.&lt;/p&gt;

7660 <title>Autodetecting Client setup for roaming workstations in Debian Edu</title>
7661 <link>http://people.skolelinux.org/pere/blog/Autodetecting_Client_setup_for_roaming_workstations_in_Debian_Edu.html</link>
7662 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Autodetecting_Client_setup_for_roaming_workstations_in_Debian_Edu.html</guid>
7663 <pubDate>Sat, 7 Aug 2010 14:45:00 +0200</pubDate>
7664 <description>&lt;p&gt;A few days ago, I
7665 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/Debian_Edu_roaming_workstation___at_the_university_of_Oslo.html&quot;&gt;tried
7666 to install&lt;/a&gt; a Roaming workation profile from Debian Edu/Squeeze
7667 while on the university network here at the University of Oslo, and
7668 noticed how much had to change to get it operational using the
7669 university infrastructure. It was fairly easy, but it occured to me
7670 that Debian Edu would improve a lot if I could get the client to
7671 connect without any changes at all, and thus let the client configure
7672 itself during installation and first boot to use the infrastructure
7673 around it. Now I am a huge step further along that road.&lt;/p&gt;
7674
7675 &lt;p&gt;With our current squeeze-test packages, I can select the roaming
7676 workstation profile and get a working laptop connecting to the
7677 university LDAP server for user and group and our active directory
7678 servers for Kerberos authentication. All this without any
7679 configuration at all during installation. My users home directory got
7680 a bookmark in the KDE menu to mount it via SMB, with the correct URL.
7681 In short, openldap and sssd is correctly configured. In addition to
7682 this, the client look for http://wpad/wpad.dat to configure a web
7683 proxy, and when it fail to find it no proxy settings are stored in
7684 /etc/environment and /etc/apt/apt.conf. Iceweasel and KDE is
7685 configured to look for the same wpad configuration and also do not use
7686 a proxy when at the university network. If the machine is moved to a
7687 network with such wpad setup, it would automatically use it when DHCP
7688 gave it a IP address.&lt;/p&gt;
7689
7690 &lt;p&gt;The LDAP server is located using DNS, by first looking for the DNS
7691 entry ldap.$domain. If this do not exist, it look for the
7692 _ldap._tcp.$domain SRV records and use the first one as the LDAP
7693 server. Next, it connects to the LDAP server and search all
7694 namingContexts entries for posixAccount or posixGroup objects, and
7695 pick the first one as the LDAP base. For Kerberos, a similar
7696 algorithm is used to locate the LDAP server, and the realm is the
7697 uppercase version of $domain.&lt;/p&gt;
7698
7699 &lt;p&gt;So, what is not working, you might ask. SMB mounting my home
7700 directory do not work. No idea why, but suspected the incorrect
7701 Kerberos settings in /etc/krb5.conf and /etc/samba/smb.conf might be
7702 the cause. These are not properly configured during installation, and
7703 had to be hand-edited to get the correct Kerberos realm and server,
7704 but SMB mounting still do not work. :(&lt;/p&gt;
7705
7706 &lt;p&gt;With this automatic configuration in place, I expect a Debian Edu
7707 roaming profile installation would be able to automatically detect and
7708 connect to any site using LDAP and Kerberos for NSS directory and PAM
7709 authentication. It should also work out of the box in a Active
7710 Directory environment providing posixAccount and posixGroup objects
7711 with UID and GID values.&lt;/p&gt;
7712
7713 &lt;p&gt;If you want to help out with implementing these things for Debian
7714 Edu, please contact us on debian-edu@lists.debian.org.&lt;/p&gt;

7719 <title>Debian Edu roaming workstation - at the university of Oslo</title>
7720 <link>http://people.skolelinux.org/pere/blog/Debian_Edu_roaming_workstation___at_the_university_of_Oslo.html</link>
7721 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Debian_Edu_roaming_workstation___at_the_university_of_Oslo.html</guid>
7722 <pubDate>Tue, 3 Aug 2010 23:30:00 +0200</pubDate>
7723 <description>&lt;p&gt;The new roaming workstation profile in Debian Edu/Squeeze is fairly
7724 similar to the laptop setup am I working on using Ubuntu for the
7725 University of Oslo, and just for the heck of it, I tested today how
7726 hard it would be to integrate that profile into the university
7727 infrastructure. In this case, it is the university LDAP server,
7728 Active Directory Kerberos server and SMB mounting from the Netapp file
7729 servers.&lt;/p&gt;
7730
7731 &lt;p&gt;I was pleasantly surprised that the only three files needed to be
7732 changed (/etc/sssd/sssd.conf, /etc/ldap.conf and
7733 /etc/mklocaluser.d/20-debian-edu-config) and one file had to be added
7734 (/usr/share/perl5/Debian/Edu_Local.pm), to get the client working.
7735 Most of the changes were to get the client to use the university LDAP
7736 for NSS and Kerberos server for PAM, but one was to change a hard
7737 coded DNS domain name in the mklocaluser hook from .intern to
7738 .uio.no.&lt;/p&gt;
7739
7740 &lt;p&gt;This testing was so encouraging, that I went ahead and adjusted the
7741 Debian Edu scripts and setup in subversion to centralise the roaming
7742 workstation setup a bit more and avoid the hardcoded DNS domain name,
7743 so that when I test this tomorrow, I expect to get away with modifying
7744 only /etc/sssd/sssd.conf and /etc/ldap.conf to get it to use the
7745 university servers.&lt;/p&gt;
7746
7747 &lt;p&gt;My goal is to get the clients to have no hardcoded settings and
7748 fetch all their initial setup during installation and first boot, to
7749 allow them to be inserted also into environments where the default
7750 setup in Debian Edu has been changed or as with the university, where
7751 the environment is different but provides the protocols Debian Edu
7752 uses.&lt;/p&gt;

7760 <pubDate>Tue, 27 Jul 2010 17:45:00 +0200</pubDate>
7761 <description>&lt;p&gt;I just posted this announcement culminating several months of work
7762 with the next Debian Edu release. Not nearly done, but one major step
7763 completed.&lt;/p&gt;
7764
7765 &lt;blockquote&gt;
7766 &lt;p&gt;This is the first test release based on Squeeze. The focus of this
7767 release is to test the user application selection. To have a look,
7768 install the standalone profile and let the developers know if the set
7769 of installed packages i.e. applications should be modified. If some
7770 user application is missing, or if there are some applications that no
7771 longer make sense to be included in Debian Edu, please let us know.
7772 Also, if a useful application is missing the translation for your
7773 language of choice, please let us know too.&lt;/p&gt;
7774
7775 &lt;p&gt;In addition, feedback and help to polish the desktop (menus,
7776 artwork, starters, etc.) is appreciated. We would like to ship a nice
7777 and handy KDE4 desktop targeted for schools out of the box.&lt;/p&gt;
7778
7779 &lt;p&gt;The other profiles should be installable, but there is a lot more
7780 work left to be done before they are ready, so do not expect to
7781 much.&lt;/p&gt;
7782
7783 &lt;p&gt;Changes compared to the lenny based version&lt;/p&gt;
7784
7785 &lt;ul&gt;
7786 &lt;li&gt;Everything from Debian Squeeze
7787 &lt;ul&gt;
7788 &lt;li&gt;Desktop environment KDE 4.4 =&gt; the new KDE desktop in
7789 combination with some new artwork
7790 &lt;li&gt;Web browser Iceweasel 3.5

7798 &lt;li&gt;Video editor Kdenlive 0.7.7 (new application)
7799 &lt;/ul&gt;&lt;/li&gt;
7800 &lt;li&gt;Now using Kerberos for password checking (migration not finished).
7801 Enabled for:
7802 &lt;ul&gt;
7803 &lt;li&gt;PAM
7804 &lt;li&gt;LDAP
7805 &lt;li&gt;IMAP
7806 &lt;li&gt;SMTP (sender verification)
7807 &lt;/ul&gt;
7808 &lt;/li&gt;
7809 &lt;li&gt;New experimental roaming workstation profile for laptops.&lt;/li&gt;
7810 &lt;li&gt;Show welcome page to users when they first log in. The URL is
7811 fetched from LDAP.&lt;/li&gt;
7812 &lt;li&gt;New LXDE desktop option, in addition to KDE (default) and Gnome.&lt;/li&gt;
7813 &lt;li&gt;General cleanup (not finished)&lt;/li&gt;
7814 &lt;/ul&gt;
7815 &lt;p&gt;The following features are not working as they should&lt;/p&gt;
7816
7817 &lt;ul&gt;
7818 &lt;li&gt;No web based administration tool for creating users and groups. The
7819 scripts ldap-createuser-krb and ldap-add-user-to-group can be used
7820 for testing.&lt;/li&gt;
7821 &lt;li&gt;DVD installs are missing debian-installer images for the PXE boot,
7822 and do not set up the PXE menu on eth0 because of this. LTSP
7823 clients should still boot from eth1 on thin client servers.&lt;/li&gt;
7824 &lt;li&gt;The restructured KDE menu is not implemented.&lt;/li&gt;
7825 &lt;li&gt;The LDAP server setup need to be reviewed for security.&lt;/li&gt;
7826 &lt;li&gt;The LDAP directory structure need to be reworked.&lt;/li&gt;
7827 &lt;li&gt;Different sets of packages are installed when using the DVD and the
7828 netinst CD. More packages are installed using the netinst CD.&lt;/li&gt;
7829 &lt;li&gt;The jackd package fail to install. This is believed to be caused by

7876 <title>One step closer to single signon in Debian Edu</title>
7877 <link>http://people.skolelinux.org/pere/blog/One_step_closer_to_single_signon_in_Debian_Edu.html</link>
7878 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/One_step_closer_to_single_signon_in_Debian_Edu.html</guid>
7879 <pubDate>Sun, 25 Jul 2010 10:00:00 +0200</pubDate>
7880 <description>&lt;p&gt;The last few months me and the other Debian Edu developers have
7881 been working hard to get the Debian/Squeeze based version of Debian
7882 Edu/Skolelinux into shape. This future version will use Kerberos for
7883 authentication, and services are slowly migrated to single signon,
7884 getting rid of password questions one at the time.&lt;/p&gt;
7885
7886 &lt;p&gt;It will also feature a roaming workstation profile with local home
7887 directory, for laptops that are only some times on the Skolelinux
7888 network, and for this profile a shortcut is created in Gnome and KDE
7889 to gain access to the users home directory on the file server. This
7890 shortcut uses SMB at the moment, and yesterday I had time to test if
7891 SMB mounting had started working in KDE after we added the cifs-utils
7892 package. I was pleasantly surprised how well it worked.&lt;/p&gt;
7893
7894 &lt;p&gt;Thanks to the recent changes to our samba configuration to get it
7895 to use Kerberos for authentication, there were no question about user
7896 password when mounting the SMB volume. A simple click on the shortcut
7897 in the KDE menu, and a window with the home directory popped
7898 up. :)&lt;/p&gt;
7899
7900 &lt;p&gt;One step closer to a single signon solution out of the box in
7901 Debian Edu. We already had PAM, LDAP, IMAP and SMTP in place, and now
7902 also Samba. Next step is Cups and hopefully also NFS.&lt;/p&gt;
7903
7904 &lt;p&gt;We had planned a alpha0 release of Debian Edu for today, but thanks
7905 to the autobuilder administrators for some architectures being slow to
7906 sign packages, we are still missing the fixed LTSP package we need for
7907 the release. It was uploaded three days ago with urgency=high, and if
7908 it had entered testing yesterday we would have been able to test it in
7909 time for a alpha0 release today. As the binaries for ia64 and powerpc
7910 still not uploaded to the Debian archive, we need to delay the alpha
7911 release another day.&lt;/p&gt;
7912
7913 &lt;p&gt;If you want to help out with implementing Kerberos for Debian Edu,
7914 please contact us on debian-edu@lists.debian.org.&lt;/p&gt;

7923 <description>&lt;p&gt;This is a
7924 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/Time_for_new__LDAP_schemas_replacing_RFC_2307_.html&quot;&gt;followup&lt;/a&gt;

7926 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/Idea_for_a_change_to_LDAP_schemas_allowing_DNS_and_DHCP_info_to_be_combined_into_one_object.html&quot;&gt;previous

7929 all&lt;/a&gt; the computer related LDAP objects in Debian Edu.&lt;/p&gt;
7930
7931 &lt;p&gt;As a step to try to see if it possible to merge the DNS and DHCP
7932 LDAP objects, I have had a look at how the packages pdns-backend-ldap
7933 and dhcp3-server-ldap in Debian use the LDAP server. The two
7934 implementations are quite different in how they use LDAP.&lt;/p&gt;
7935
7936 To get this information, I started slapd with debugging enabled and
7937 dumped the debug output to a file to get the LDAP searches performed
7938 on a Debian Edu main-server. Here is a summary.
7939
7940 &lt;p&gt;&lt;strong&gt;powerdns&lt;/strong&gt;&lt;/p&gt;
7941
7942 &lt;a href=&quot;http://www.linuxnetworks.de/doc/index.php/PowerDNS_LDAP_Backend&quot;&gt;Clues
7943 on how to&lt;/a&gt; set up PowerDNS to use a LDAP backend is available on
7944 the web.
7945
7946 &lt;p&gt;PowerDNS have two modes of operation using LDAP as its backend.
7947 One &quot;strict&quot; mode where the forward and reverse DNS lookups are done
7948 using the same LDAP objects, and a &quot;tree&quot; mode where the forward and
7949 reverse entries are in two different subtrees in LDAP with a structure
7950 based on the DNS names, as in tjener.intern and
7951 2.2.0.10.in-addr.arpa.&lt;/p&gt;
7952
7953 &lt;p&gt;In tree mode, the server is set up to use a LDAP subtree as its
7954 base, and uses a &quot;base&quot; scoped search for the DNS name by adding
7955 &quot;dc=tjener,dc=intern,&quot; to the base with a filter for
7956 &quot;(associateddomain=tjener.intern)&quot; for the forward entry and
7957 &quot;dc=2,dc=2,dc=0,dc=10,dc=in-addr,dc=arpa,&quot; with a filter for
7958 &quot;(associateddomain=2.2.0.10.in-addr.arpa)&quot; for the reverse entry. For
7959 forward entries, it is looking for attributes named dnsttl, arecord,
7960 nsrecord, cnamerecord, soarecord, ptrrecord, hinforecord, mxrecord,
7961 txtrecord, rprecord, afsdbrecord, keyrecord, aaaarecord, locrecord,
7962 srvrecord, naptrrecord, kxrecord, certrecord, dsrecord, sshfprecord,
7963 ipseckeyrecord, rrsigrecord, nsecrecord, dnskeyrecord, dhcidrecord,
7964 spfrecord and modifytimestamp. For reverse entries it is looking for
7965 the attributes dnsttl, arecord, nsrecord, cnamerecord, soarecord,
7966 ptrrecord, hinforecord, mxrecord, txtrecord, rprecord, aaaarecord,
7967 locrecord, srvrecord, naptrrecord and modifytimestamp. The equivalent
7968 ldapsearch commands could look like this:&lt;/p&gt;
7969
7970 &lt;blockquote&gt;&lt;pre&gt;
7971 ldapsearch -h ldap \
7972 -b dc=tjener,dc=intern,ou=hosts,dc=skole,dc=skolelinux,dc=no \
7973 -s base -x &#39;(associateddomain=tjener.intern)&#39; dNSTTL aRecord nSRecord \
7974 cNAMERecord sOARecord pTRRecord hInfoRecord mXRecord tXTRecord \
7975 rPRecord aFSDBRecord KeyRecord aAAARecord lOCRecord sRVRecord \
7976 nAPTRRecord kXRecord certRecord dSRecord sSHFPRecord iPSecKeyRecord \
7977 rRSIGRecord nSECRecord dNSKeyRecord dHCIDRecord sPFRecord modifyTimestamp
7978
7979 ldapsearch -h ldap \
7980 -b dc=2,dc=2,dc=0,dc=10,dc=in-addr,dc=arpa,ou=hosts,dc=skole,dc=skolelinux,dc=no \
7981 -s base -x &#39;(associateddomain=2.2.0.10.in-addr.arpa)&#39;
7982 dnsttl, arecord, nsrecord, cnamerecord soarecord ptrrecord \
7983 hinforecord mxrecord txtrecord rprecord aaaarecord locrecord \
7984 srvrecord naptrrecord modifytimestamp
7985 &lt;/pre&gt;&lt;/blockquote&gt;
7986
7987 &lt;p&gt;In Debian Edu/Lenny, the PowerDNS tree mode is used with
7988 ou=hosts,dc=skole,dc=skolelinux,dc=no as the base, and these are two
7989 example LDAP objects used there. In addition to these objects, the
7990 parent objects all th way up to ou=hosts,dc=skole,dc=skolelinux,dc=no
7991 also exist.&lt;/p&gt;
7992
7993 &lt;blockquote&gt;&lt;pre&gt;
7994 dn: dc=tjener,dc=intern,ou=hosts,dc=skole,dc=skolelinux,dc=no
7995 objectclass: top
7996 objectclass: dnsdomain
7997 objectclass: domainrelatedobject
7998 dc: tjener
7999 arecord: 10.0.2.2
8000 associateddomain: tjener.intern
8001
8002 dn: dc=2,dc=2,dc=0,dc=10,dc=in-addr,dc=arpa,ou=hosts,dc=skole,dc=skolelinux,dc=no
8003 objectclass: top
8004 objectclass: dnsdomain2
8005 objectclass: domainrelatedobject
8006 dc: 2
8007 ptrrecord: tjener.intern
8008 associateddomain: 2.2.0.10.in-addr.arpa
8009 &lt;/pre&gt;&lt;/blockquote&gt;
8010
8011 &lt;p&gt;In strict mode, the server behaves differently. When looking for
8012 forward DNS entries, it is doing a &quot;subtree&quot; scoped search with the
8013 same base as in the tree mode for a object with filter
8014 &quot;(associateddomain=tjener.intern)&quot; and requests the attributes dnsttl,
8015 arecord, nsrecord, cnamerecord, soarecord, ptrrecord, hinforecord,
8016 mxrecord, txtrecord, rprecord, aaaarecord, locrecord, srvrecord,
8017 naptrrecord and modifytimestamp. For reverse entires it also do a
8018 subtree scoped search but this time the filter is &quot;(arecord=10.0.2.2)&quot;
8019 and the requested attributes are associateddomain, dnsttl and
8020 modifytimestamp. In short, in strict mode the objects with ptrrecord
8021 go away, and the arecord attribute in the forward object is used
8022 instead.&lt;/p&gt;
8023
8024 &lt;p&gt;The forward and reverse searches can be simulated using ldapsearch
8025 like this:&lt;/p&gt;
8026
8027 &lt;blockquote&gt;&lt;pre&gt;
8028 ldapsearch -h ldap -b ou=hosts,dc=skole,dc=skolelinux,dc=no -s sub -x \
8029 &#39;(associateddomain=tjener.intern)&#39; dNSTTL aRecord nSRecord \
8030 cNAMERecord sOARecord pTRRecord hInfoRecord mXRecord tXTRecord \
8031 rPRecord aFSDBRecord KeyRecord aAAARecord lOCRecord sRVRecord \
8032 nAPTRRecord kXRecord certRecord dSRecord sSHFPRecord iPSecKeyRecord \
8033 rRSIGRecord nSECRecord dNSKeyRecord dHCIDRecord sPFRecord modifyTimestamp
8034
8035 ldapsearch -h ldap -b ou=hosts,dc=skole,dc=skolelinux,dc=no -s sub -x \
8036 &#39;(arecord=10.0.2.2)&#39; associateddomain dnsttl modifytimestamp
8037 &lt;/pre&gt;&lt;/blockquote&gt;
8038
8039 &lt;p&gt;In addition to the forward and reverse searches , there is also a
8040 search for SOA records, which behave similar to the forward and
8041 reverse lookups.&lt;/p&gt;
8042
8043 &lt;p&gt;A thing to note with the PowerDNS behaviour is that it do not
8044 specify any objectclass names, and instead look for the attributes it
8045 need to generate a DNS reply. This make it able to work with any
8046 objectclass that provide the needed attributes.&lt;/p&gt;
8047
8048 &lt;p&gt;The attributes are normally provided in the cosine (RFC 1274) and
8049 dnsdomain2 schemas. The latter is used for reverse entries like
8050 ptrrecord and recent DNS additions like aaaarecord and srvrecord.&lt;/p&gt;
8051
8052 &lt;p&gt;In Debian Edu, we have created DNS objects using the object classes
8053 dcobject (for dc), dnsdomain or dnsdomain2 (structural, for the DNS
8054 attributes) and domainrelatedobject (for associatedDomain). The use
8055 of structural object classes make it impossible to combine these
8056 classes with the object classes used by DHCP.&lt;/p&gt;
8057
8058 &lt;p&gt;There are other schemas that could be used too, for example the
8059 dnszone structural object class used by Gosa and bind-sdb for the DNS
8060 attributes combined with the domainrelatedobject object class, but in
8061 this case some unused attributes would have to be included as well
8062 (zonename and relativedomainname).&lt;/p&gt;
8063
8064 &lt;p&gt;My proposal for Debian Edu would be to switch PowerDNS to strict
8065 mode and not use any of the existing objectclasses (dnsdomain,
8066 dnsdomain2 and dnszone) when one want to combine the DNS information
8067 with DHCP information, and instead create a auxiliary object class
8068 defined something like this (using the attributes defined for
8069 dnsdomain and dnsdomain2 or dnszone):&lt;/p&gt;
8070
8071 &lt;blockquote&gt;&lt;pre&gt;
8072 objectclass ( some-oid NAME &#39;dnsDomainAux&#39;
8073 SUP top
8074 AUXILIARY
8075 MAY ( ARecord $ MDRecord $ MXRecord $ NSRecord $ SOARecord $ CNAMERecord $
8076 DNSTTL $ DNSClass $ PTRRecord $ HINFORecord $ MINFORecord $
8077 TXTRecord $ SIGRecord $ KEYRecord $ AAAARecord $ LOCRecord $
8078 NXTRecord $ SRVRecord $ NAPTRRecord $ KXRecord $ CERTRecord $
8079 A6Record $ DNAMERecord
8080 ))
8081 &lt;/pre&gt;&lt;/blockquote&gt;
8082
8083 &lt;p&gt;This will allow any object to become a DNS entry when combined with
8084 the domainrelatedobject object class, and allow any entity to include
8085 all the attributes PowerDNS wants. I&#39;ve sent an email to the PowerDNS
8086 developers asking for their view on this schema and if they are
8087 interested in providing such schema with PowerDNS, and I hope my
8088 message will be accepted into their mailing list soon.&lt;/p&gt;
8089
8090 &lt;p&gt;&lt;strong&gt;ISC dhcp&lt;/strong&gt;&lt;/p&gt;
8091
8092 &lt;p&gt;The DHCP server searches for specific objectclass and requests all
8093 the object attributes, and then uses the attributes it want. This
8094 make it harder to figure out exactly what attributes are used, but
8095 thanks to the working example in Debian Edu I can at least get an idea
8096 what is needed without having to read the source code.&lt;/p&gt;
8097
8098 &lt;p&gt;In the DHCP server configuration, the LDAP base to use and the
8099 search filter to use to locate the correct dhcpServer entity is
8100 stored. These are the relevant entries from
8101 /etc/dhcp3/dhcpd.conf:&lt;/p&gt;
8102
8103 &lt;blockquote&gt;&lt;pre&gt;
8104 ldap-base-dn &quot;dc=skole,dc=skolelinux,dc=no&quot;;
8105 ldap-dhcp-server-cn &quot;dhcp&quot;;
8106 &lt;/pre&gt;&lt;/blockquote&gt;
8107
8108 &lt;p&gt;The DHCP server uses this information to nest all the DHCP
8109 configuration it need. The cn &quot;dhcp&quot; is located using the given LDAP
8110 base and the filter &quot;(&amp;(objectClass=dhcpServer)(cn=dhcp))&quot;. The
8111 search result is this entry:&lt;/p&gt;
8112
8113 &lt;blockquote&gt;&lt;pre&gt;
8114 dn: cn=dhcp,dc=skole,dc=skolelinux,dc=no
8115 cn: dhcp
8116 objectClass: top
8117 objectClass: dhcpServer
8118 dhcpServiceDN: cn=DHCP Config,dc=skole,dc=skolelinux,dc=no
8119 &lt;/pre&gt;&lt;/blockquote&gt;
8120
8121 &lt;p&gt;The content of the dhcpServiceDN attribute is next used to locate the
8122 subtree with DHCP configuration. The DHCP configuration subtree base
8123 is located using a base scope search with base &quot;cn=DHCP
8124 Config,dc=skole,dc=skolelinux,dc=no&quot; and filter
8125 &quot;(&amp;(objectClass=dhcpService)(|(dhcpPrimaryDN=cn=dhcp,dc=skole,dc=skolelinux,dc=no)(dhcpSecondaryDN=cn=dhcp,dc=skole,dc=skolelinux,dc=no)))&quot;.
8126 The search result is this entry:&lt;/p&gt;
8127
8128 &lt;blockquote&gt;&lt;pre&gt;
8129 dn: cn=DHCP Config,dc=skole,dc=skolelinux,dc=no
8130 cn: DHCP Config
8131 objectClass: top
8132 objectClass: dhcpService
8133 objectClass: dhcpOptions
8134 dhcpPrimaryDN: cn=dhcp, dc=skole,dc=skolelinux,dc=no
8135 dhcpStatements: ddns-update-style none
8136 dhcpStatements: authoritative
8137 dhcpOption: smtp-server code 69 = array of ip-address
8138 dhcpOption: www-server code 72 = array of ip-address
8139 dhcpOption: wpad-url code 252 = text
8140 &lt;/pre&gt;&lt;/blockquote&gt;
8141
8142 &lt;p&gt;Next, the entire subtree is processed, one level at the time. When
8143 all the DHCP configuration is loaded, it is ready to receive requests.
8144 The subtree in Debian Edu contain objects with object classes
8145 top/dhcpService/dhcpOptions, top/dhcpSharedNetwork/dhcpOptions,
8146 top/dhcpSubnet, top/dhcpGroup and top/dhcpHost. These provide options
8147 and information about netmasks, dynamic range etc. Leaving out the
8148 details here because it is not relevant for the focus of my
8149 investigation, which is to see if it is possible to merge dns and dhcp
8150 related computer objects.&lt;/p&gt;
8151
8152 &lt;p&gt;When a DHCP request come in, LDAP is searched for the MAC address
8153 of the client (00:00:00:00:00:00 in this example), using a subtree
8154 scoped search with &quot;cn=DHCP Config,dc=skole,dc=skolelinux,dc=no&quot; as
8155 the base and &quot;(&amp;(objectClass=dhcpHost)(dhcpHWAddress=ethernet
8156 00:00:00:00:00:00))&quot; as the filter. This is what a host object look
8157 like:&lt;/p&gt;
8158
8159 &lt;blockquote&gt;&lt;pre&gt;
8160 dn: cn=hostname,cn=group1,cn=THINCLIENTS,cn=DHCP Config,dc=skole,dc=skolelinux,dc=no
8161 cn: hostname
8162 objectClass: top
8163 objectClass: dhcpHost
8164 dhcpHWAddress: ethernet 00:00:00:00:00:00
8165 dhcpStatements: fixed-address hostname
8166 &lt;/pre&gt;&lt;/blockquote&gt;
8167
8168 &lt;p&gt;There is less flexiblity in the way LDAP searches are done here.
8169 The object classes need to have fixed names, and the configuration
8170 need to be stored in a fairly specific LDAP structure. On the
8171 positive side, the invidiual dhcpHost entires can be anywhere without
8172 the DN pointed to by the dhcpServer entries. The latter should make
8173 it possible to group all host entries in a subtree next to the
8174 configuration entries, and this subtree can also be shared with the
8175 DNS server if the schema proposed above is combined with the dhcpHost
8176 structural object class.
8177
8178 &lt;p&gt;&lt;strong&gt;Conclusion&lt;/strong&gt;&lt;/p&gt;
8179
8180 &lt;p&gt;The PowerDNS implementation seem to be very flexible when it come
8181 to which LDAP schemas to use. While its &quot;tree&quot; mode is rigid when it
8182 come to the the LDAP structure, the &quot;strict&quot; mode is very flexible,
8183 allowing DNS objects to be stored anywhere under the base cn specified
8184 in the configuration.&lt;/p&gt;
8185
8186 &lt;p&gt;The DHCP implementation on the other hand is very inflexible, both
8187 regarding which LDAP schemas to use and which LDAP structure to use.
8188 I guess one could implement ones own schema, as long as the
8189 objectclasses and attributes have the names used, but this do not
8190 really help when the DHCP subtree need to have a fairly fixed
8191 structure.&lt;/p&gt;
8192
8193 &lt;p&gt;Based on the observed behaviour, I suspect a LDAP structure like
8194 this might work for Debian Edu:&lt;/p&gt;
8195
8196 &lt;blockquote&gt;&lt;pre&gt;
8197 ou=services
8198 cn=machine-info (dhcpService) - dhcpServiceDN points here
8199 cn=dhcp (dhcpServer)
8200 cn=dhcp-internal (dhcpSharedNetwork/dhcpOptions)
8201 cn=10.0.2.0 (dhcpSubnet)
8202 cn=group1 (dhcpGroup/dhcpOptions)
8203 cn=dhcp-thinclients (dhcpSharedNetwork/dhcpOptions)
8204 cn=192.168.0.0 (dhcpSubnet)
8205 cn=group1 (dhcpGroup/dhcpOptions)
8206 ou=machines - PowerDNS base points here
8207 cn=hostname (dhcpHost/domainrelatedobject/dnsDomainAux)
8208 &lt;/pre&gt;&lt;/blockquote&gt;
8209
8210 &lt;P&gt;This is not tested yet. If the DHCP server require the dhcpHost
8211 entries to be in the dhcpGroup subtrees, the entries can be stored
8212 there instead of a common machines subtree, and the PowerDNS base
8213 would have to be moved one level up to the machine-info subtree.&lt;/p&gt;
8214
8215 &lt;p&gt;The combined object under the machines subtree would look something
8216 like this:&lt;/p&gt;
8217
8218 &lt;blockquote&gt;&lt;pre&gt;
8219 dn: dc=hostname,ou=machines,cn=machine-info,dc=skole,dc=skolelinux,dc=no
8220 dc: hostname
8221 objectClass: top
8222 objectClass: dhcpHost
8223 objectclass: domainrelatedobject
8224 objectclass: dnsDomainAux
8225 associateddomain: hostname.intern
8226 arecord: 10.11.12.13
8227 dhcpHWAddress: ethernet 00:00:00:00:00:00
8228 dhcpStatements: fixed-address hostname.intern
8229 &lt;/pre&gt;&lt;/blockquote&gt;
8230
8231 &lt;/p&gt;One could even add the LTSP configuration associated with a given
8232 machine, as long as the required attributes are available in a
8233 auxiliary object class.&lt;/p&gt;

8238 <title>Combining PowerDNS and ISC DHCP LDAP objects</title>
8239 <link>http://people.skolelinux.org/pere/blog/Combining_PowerDNS_and_ISC_DHCP_LDAP_objects.html</link>
8240 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Combining_PowerDNS_and_ISC_DHCP_LDAP_objects.html</guid>
8241 <pubDate>Wed, 14 Jul 2010 23:45:00 +0200</pubDate>
8242 <description>&lt;p&gt;For a while now, I have wanted to find a way to change the DNS and
8243 DHCP services in Debian Edu to use the same LDAP objects for a given
8244 computer, to avoid the possibility of having a inconsistent state for
8245 a computer in LDAP (as in DHCP but no DNS entry or the other way
8246 around) and make it easier to add computers to LDAP.&lt;/p&gt;
8247
8248 &lt;p&gt;I&#39;ve looked at how powerdns and dhcpd is using LDAP, and using this
8249 information finally found a solution that seem to work.&lt;/p&gt;
8250
8251 &lt;p&gt;The old setup required three LDAP objects for a given computer.
8252 One forward DNS entry, one reverse DNS entry and one DHCP entry. If
8253 we switch powerdns to use its strict LDAP method (ldap-method=strict
8254 in pdns-debian-edu.conf), the forward and reverse DNS entries are
8255 merged into one while making it impossible to transfer the reverse map
8256 to a slave DNS server.&lt;/p&gt;
8257
8258 &lt;p&gt;If we also replace the object class used to get the DNS related
8259 attributes to one allowing these attributes to be combined with the
8260 dhcphost object class, we can merge the DNS and DHCP entries into one.
8261 I&#39;ve written such object class in the dnsdomainaux.schema file (need
8262 proper OIDs, but that is a minor issue), and tested the setup. It
8263 seem to work.&lt;/p&gt;
8264
8265 &lt;p&gt;With this test setup in place, we can get away with one LDAP object
8266 for both DNS and DHCP, and even the LTSP configuration I suggested in
8267 an earlier email. The combined LDAP object will look something like
8268 this:&lt;/p&gt;
8269
8270 &lt;blockquote&gt;&lt;pre&gt;
8271 dn: cn=hostname,cn=group1,cn=THINCLIENTS,cn=DHCP Config,dc=skole,dc=skolelinux,dc=no
8272 cn: hostname
8273 objectClass: dhcphost
8274 objectclass: domainrelatedobject
8275 objectclass: dnsdomainaux
8276 associateddomain: hostname.intern
8277 arecord: 10.11.12.13
8278 dhcphwaddress: ethernet 00:00:00:00:00:00
8279 dhcpstatements: fixed-address hostname
8280 ldapconfigsound: Y
8281 &lt;/pre&gt;&lt;/blockquote&gt;
8282
8283 &lt;p&gt;The DNS server uses the associateddomain and arecord entries, while
8284 the DHCP server uses the dhcphwaddress and dhcpstatements entries
8285 before asking DNS to resolve the fixed-adddress. LTSP will use
8286 dhcphwaddress or associateddomain and the ldapconfig* attributes.&lt;/p&gt;
8287
8288 &lt;p&gt;I am not yet sure if I can get the DHCP server to look for its
8289 dhcphost in a different location, to allow us to put the objects
8290 outside the &quot;DHCP Config&quot; subtree, but hope to figure out a way to do
8291 that. If I can&#39;t figure out a way to do that, we can still get rid of
8292 the hosts subtree and move all its content into the DHCP Config tree
8293 (which probably should be renamed to be more related to the new
8294 content. I suspect cn=dnsdhcp,ou=services or something like that
8295 might be a good place to put it.&lt;/p&gt;
8296

8303 <title>Idea for storing LTSP configuration in LDAP</title>
8304 <link>http://people.skolelinux.org/pere/blog/Idea_for_storing_LTSP_configuration_in_LDAP.html</link>
8305 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Idea_for_storing_LTSP_configuration_in_LDAP.html</guid>
8306 <pubDate>Sun, 11 Jul 2010 22:00:00 +0200</pubDate>
8307 <description>&lt;p&gt;Vagrant mentioned on IRC today that ltsp_config now support
8308 sourcing files from /usr/share/ltsp/ltsp_config.d/ on the thin
8309 clients, and that this can be used to fetch configuration from LDAP if
8310 Debian Edu choose to store configuration there.&lt;/p&gt;
8311
8312 &lt;p&gt;Armed with this information, I got inspired and wrote a test module
8313 to get configuration from LDAP. The idea is to look up the MAC
8314 address of the client in LDAP, and look for attributes on the form
8315 ltspconfigsetting=value, and use this to export SETTING=value to the
8316 LTSP clients.&lt;/p&gt;
8317
8318 &lt;p&gt;The goal is to be able to store the LTSP configuration attributes
8319 in a &quot;computer&quot; LDAP object used by both DNS and DHCP, and thus
8320 allowing us to store all information about a computer in one place.&lt;/p&gt;
8321
8322 &lt;p&gt;This is a untested draft implementation, and I welcome feedback on
8323 this approach. A real LDAP schema for the ltspClientAux objectclass
8324 need to be written. Comments, suggestions, etc?&lt;/p&gt;
8325
8326 &lt;blockquote&gt;&lt;pre&gt;
8327 # Store in /opt/ltsp/$arch/usr/share/ltsp/ltsp_config.d/ldap-config
8328 #
8329 # Fetch LTSP client settings from LDAP based on MAC address
8330 #
8331 # Uses ethernet address as stored in the dhcpHost objectclass using
8332 # the dhcpHWAddress attribute or ethernet address stored in the
8333 # ieee802Device objectclass with the macAddress attribute.
8334 #
8335 # This module is written to be schema agnostic, and only depend on the
8336 # existence of attribute names.
8337 #
8338 # The LTSP configuration variables are saved directly using a
8339 # ltspConfig prefix and uppercasing the rest of the attribute name.
8340 # To set the SERVER variable, set the ltspConfigServer attribute.
8341 #
8342 # Some LDAP schema should be created with all the relevant
8343 # configuration settings. Something like this should work:
8344 #
8345 # objectclass ( 1.1.2.2 NAME &#39;ltspClientAux&#39;
8346 # SUP top
8347 # AUXILIARY
8348 # MAY ( ltspConfigServer $ ltsConfigSound $ ... )
8349
8350 LDAPSERVER=$(debian-edu-ldapserver)
8351 if [ &quot;$LDAPSERVER&quot; ] ; then
8352 LDAPBASE=$(debian-edu-ldapserver -b)
8353 for MAC in $(LANG=C ifconfig |grep -i hwaddr| awk &#39;{print $5}&#39;|sort -u) ; do
8354 filter=&quot;(|(dhcpHWAddress=ethernet $MAC)(macAddress=$MAC))&quot;
8355 ldapsearch -h &quot;$LDAPSERVER&quot; -b &quot;$LDAPBASE&quot; -v -x &quot;$filter&quot; | \
8356 grep &#39;^ltspConfig&#39; | while read attr value ; do
8357 # Remove prefix and convert to upper case
8358 attr=$(echo $attr | sed &#39;s/^ltspConfig//i&#39; | tr a-z A-Z)
8359 # bass value on to clients
8360 eval &quot;$attr=$value; export $attr&quot;
8361 done
8362 done
8363 fi
8364 &lt;/pre&gt;&lt;/blockquote&gt;
8365
8366 &lt;p&gt;I&#39;m not sure this shell construction will work, because I suspect
8367 the while block might end up in a subshell causing the variables set
8368 there to not show up in ltsp-config, but if that is the case I am sure
8369 the code can be restructured to make sure the variables are passed on.
8370 I expect that can be solved with some testing. :)&lt;/p&gt;
8371

8374
8375 &lt;p&gt;Update 2010-07-17: I am aware of another effort to store LTSP
8376 configuration in LDAP that was created around year 2000 by
8377 &lt;a href=&quot;http://www.pcxperience.com/thinclient/documentation/ldap.html&quot;&gt;PC
8378 Xperience, Inc., 2000&lt;/a&gt;. I found its
8379 &lt;a href=&quot;http://people.redhat.com/alikins/ltsp/ldap/&quot;&gt;files&lt;/a&gt; on a
8380 personal home page over at redhat.com.&lt;/p&gt;

8389 <description>&lt;p&gt;Since
8390 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/LUMA__a_very_nice_LDAP_GUI.html&quot;&gt;my
8391 last post&lt;/a&gt; about available LDAP tools in Debian, I was told about a
8392 LDAP GUI that is even better than luma. The java application
8393 &lt;a href=&quot;http://jxplorer.org/&quot;&gt;jXplorer&lt;/a&gt; is claimed to be capable of
8394 moving LDAP objects and subtrees using drag-and-drop, and can
8395 authenticate using Kerberos. I have only tested the Kerberos
8396 authentication, but do not have a LDAP setup allowing me to rewrite
8397 LDAP with my test user yet. It is
8398 &lt;a href=&quot;http://packages.qa.debian.org/j/jxplorer.html&quot;&gt;available in
8399 Debian&lt;/a&gt; testing and unstable at the moment. The only problem I
8400 have with it is how it handle errors. If something go wrong, its
8401 non-intuitive behaviour require me to go through some query work list
8402 and remove the failing query. Nothing big, but very annoying.&lt;/p&gt;

8410 <pubDate>Sat, 3 Jul 2010 23:55:00 +0200</pubDate>
8411 <description>&lt;p&gt;Here is a short update on my &lt;a
8412 href=&quot;http://people.skolelinux.org/~pere/debian-upgrade-testing/&quot;&gt;my
8413 Debian Lenny-&gt;Squeeze upgrade testing&lt;/a&gt;. Here is a summary of the
8414 difference for Gnome when it is upgraded by apt-get and aptitude. I&#39;m
8415 not reporting the status for KDE, because the upgrade crashes when
8416 aptitude try because of missing conflicts
8417 (&lt;a href=&quot;http://bugs.debian.org/584861&quot;&gt;#584861&lt;/a&gt; and
8418 &lt;a href=&quot;http://bugs.debian.org/585716&quot;&gt;#585716&lt;/a&gt;).&lt;/p&gt;
8419
8420 &lt;p&gt;At the end of the upgrade test script, dpkg -l is executed to get a
8421 complete list of the installed packages. Based on this I see these
8422 differences when I did a test run today. As usual, I do not really
8423 know what the correct set of packages would be, but thought it best to
8424 publish the difference.&lt;/p&gt;

8507 <title>Caching password, user and group on a roaming Debian laptop</title>
8508 <link>http://people.skolelinux.org/pere/blog/Caching_password__user_and_group_on_a_roaming_Debian_laptop.html</link>
8509 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Caching_password__user_and_group_on_a_roaming_Debian_laptop.html</guid>
8510 <pubDate>Thu, 1 Jul 2010 11:40:00 +0200</pubDate>
8511 <description>&lt;p&gt;For a laptop, centralized user directories and password checking is
8512 a bit troubling. Laptops are typically used also when not connected
8513 to the network, and it is vital for a user to be able to log in or
8514 unlock the screen saver also when a central server is unavailable.
8515 This is possible by caching passwords and directory information (user
8516 and group attributes) locally, and the packages to do so are available
8517 in Debian. Here follow two recipes to set this up in Debian/Squeeze.
8518 It is also possible to set up in Debian/Lenny, but require more manual
8519 setup there because pam-auth-update is missing in Lenny.&lt;/p&gt;
8520
8521 &lt;h2&gt;LDAP/Kerberos + nscd + libpam-ccreds + libpam-mklocaluser/pam_mkhomedir&lt;/h2&gt;
8522
8523 This is the traditional method with a twist. The password caching is
8524 provided by libpam-ccreds (version 10-4 or later is needed on
8525 Squeeze), and the directory caching is done by nscd. The directory
8526 lookup and password checking is done using LDAP. If one want to use
8527 Kerberos for password checking the libpam-ldapd package can be
8528 replaced with libpam-krb5 or libpam-heimdal. If one is happy having a
8529 local home directory with the path listed in LDAP, one can use the
8530 pam_mkhomedir module from pam-modules to make this happen instead of
8531 using libpam-mklocaluser. A setup for pam-auth-update to enable
8532 pam_mkhomedir will have to be written until a fix for
8533 &lt;a href=&quot;http://bugs.debian.org/568577&quot;&gt;bug #568577&lt;/a&gt; is in the
8534 archive. Because I believe it is a bad idea to have local home
8535 directories using misleading paths like /site/server/partition/, I
8536 prefer to create a local user with the home directory in /home/. This
8537 is done using the libpam-mklocaluser package.&lt;/p&gt;
8538
8539 &lt;p&gt;These packages need to be installed and configured&lt;/p&gt;
8540
8541 &lt;blockquote&gt;&lt;pre&gt;
8542 libnss-ldapd libpam-ldapd nscd libpam-ccreds libpam-mklocaluser
8543 &lt;/pre&gt;&lt;/blockquote&gt;
8544
8545 &lt;p&gt;The ldapd packages will ask for LDAP connection information, and
8546 one have to fill in the values that fits ones own site. Make sure the
8547 PAM part uses encrypted connections, to make sure the password is not
8548 sent in clear text to the LDAP server. I&#39;ve been unable to get TLS
8549 certificate checking for a self signed certificate working, which make
8550 LDAP authentication unsafe for Debian Edu (nslcd is not checking if it
8551 is talking to the correct LDAP server), and very much welcome feedback
8552 on how to get this working.&lt;/p&gt;
8553
8554 &lt;p&gt;Because nscd do not have a default configuration fit for offline
8555 caching until &lt;a href=&quot;http://bugs.debian.org/485282&quot;&gt;bug #485282&lt;/a&gt;
8556 is fixed, this configuration should be used instead of the one
8557 currently in /etc/nscd.conf. The changes are in the fields
8558 reload-count and positive-time-to-live, and is based on the
8559 instructions I found in the
8560 &lt;a href=&quot;http://www.flyn.org/laptopldap/&quot;&gt;LDAP for Mobile Laptops&lt;/a&gt;

8606
8607 &lt;p&gt;While we wait for a mechanism to update /etc/nsswitch.conf
8608 automatically like the one provided in
8609 &lt;a href=&quot;http://bugs.debian.org/496915&quot;&gt;bug #496915&lt;/a&gt;, the file
8610 content need to be manually replaced to ensure LDAP is used as the
8611 directory service on the machine. /etc/nsswitch.conf should normally
8612 look like this:&lt;/p&gt;
8613
8614 &lt;blockquote&gt;&lt;pre&gt;
8615 passwd: files ldap
8616 group: files ldap
8617 shadow: files ldap
8618 hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4
8619 networks: files
8620 protocols: files
8621 services: files
8622 ethers: files
8623 rpc: files
8624 netgroup: files ldap
8625 &lt;/pre&gt;&lt;/blockquote&gt;
8626
8627 &lt;p&gt;The important parts are that ldap is listed last for passwd, group,
8628 shadow and netgroup.&lt;/p&gt;
8629
8630 &lt;p&gt;With these changes in place, any user in LDAP will be able to log
8631 in locally on the machine using for example kdm, get a local home
8632 directory created and have the password as well as user and group
8633 attributes cached.
8634
8635 &lt;h2&gt;LDAP/Kerberos + nss-updatedb + libpam-ccreds +
8636 libpam-mklocaluser/pam_mkhomedir&lt;/h2&gt;
8637
8638 &lt;p&gt;Because nscd have had its share of problems, and seem to have
8639 problems doing proper caching, I&#39;ve seen suggestions and recipes to
8640 use nss-updatedb to copy parts of the LDAP database locally when the
8641 LDAP database is available. I have not tested such setup, because I
8642 discovered sssd.&lt;/p&gt;
8643
8644 &lt;h2&gt;LDAP/Kerberos + sssd + libpam-mklocaluser&lt;/h2&gt;
8645
8646 &lt;p&gt;A more flexible and robust setup than the nscd combination
8647 mentioned earlier that has shown up recently, is the
8648 &lt;a href=&quot;https://fedorahosted.org/sssd/&quot;&gt;sssd&lt;/a&gt; package from Redhat.
8649 It is part of the &lt;a href=&quot;http://www.freeipa.org/&quot;&gt;FreeIPA&lt;/A&gt; project
8650 to provide a Active Directory like directory service for Linux
8651 machines. The sssd system combines the caching of passwords and user
8652 information into one package, and remove the need for nscd and
8653 libpam-ccreds. It support LDAP and Kerberos, but not NIS. Version
8654 1.2 do not support netgroups, but it is said that it will support this
8655 in version 1.5 expected to show up later in 2010. Because the
8656 &lt;a href=&quot;http://packages.qa.debian.org/s/sssd.html&quot;&gt;sssd package&lt;/a&gt;
8657 was missing in Debian, I ended up co-maintaining it with Werner, and
8658 version 1.2 is now in testing.
8659
8660 &lt;p&gt;These packages need to be installed and configured to get the
8661 roaming setup I want&lt;/p&gt;
8662
8663 &lt;blockquote&gt;&lt;pre&gt;
8664 libpam-sss libnss-sss libpam-mklocaluser
8665 &lt;/pre&gt;&lt;/blockquote&gt;
8666
8667 The complete setup of sssd is done by editing/creating
8668 &lt;tt&gt;/etc/sssd/sssd.conf&lt;/tt&gt;.
8669
8670 &lt;blockquote&gt;&lt;pre&gt;

8699
8700 &lt;p&gt;I got the same problem here with certificate checking. Had to set
8701 &quot;ldap_tls_reqcert = never&quot; to get it working.&lt;/p&gt;
8702
8703 &lt;p&gt;With the libnss-sss package in testing at the moment, the
8704 nsswitch.conf file is update automatically, so there is no need to
8705 modify it manually.&lt;/p&gt;

8713 <title>LUMA, a very nice LDAP GUI</title>

8715 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/LUMA__a_very_nice_LDAP_GUI.html</guid>
8716 <pubDate>Mon, 28 Jun 2010 00:30:00 +0200</pubDate>
8717 <description>&lt;p&gt;The last few days I have been looking into the status of the LDAP
8718 directory in Debian Edu, and in the process I started to miss a GUI
8719 tool to browse the LDAP tree. The only one I was able to find in
8720 Debian/Squeeze and Lenny is
8721 &lt;a href=&quot;http://luma.sourceforge.net/&quot;&gt;LUMA&lt;/a&gt;, which has proved to
8722 be a great tool to get a overview of the current LDAP directory
8723 populated by default in Skolelinux. Thanks to it, I have been able to
8724 find empty and obsolete subtrees, misplaced objects and duplicate
8725 objects. It will be installed by default in Debian/Squeeze. If you
8726 are working with LDAP, give it a go. :)&lt;/p&gt;
8727
8728 &lt;p&gt;I did notice one problem with it I have not had time to report to
8729 the BTS yet. There is no .desktop file in the package, so the tool do
8730 not show up in the Gnome and KDE menus, but only deep down in in the
8731 Debian submenu in KDE. I hope that can be fixed before Squeeze is
8732 released.&lt;/p&gt;
8733
8734 &lt;p&gt;I have not yet been able to get it to modify the tree yet. I would
8735 like to move objects and remove subtrees directly in the GUI, but have
8736 not found a way to do that with LUMA yet. So in the mean time, I use
8737 &lt;a href=&quot;http://www.lichteblau.com/ldapvi/&quot;&gt;ldapvi&lt;/a&gt; for that.&lt;/p&gt;
8738
8739 &lt;p&gt;If you have tips on other GUI tools for LDAP that might be useful
8740 in Debian Edu, please contact us on debian-edu@lists.debian.org.&lt;/p&gt;
8741
8742 &lt;p&gt;Update 2010-06-29: Ross Reedstrom tipped us about the
8743 &lt;a href=&quot;http://packages.qa.debian.org/g/gq.html&quot;&gt;gq&lt;/a&gt; package as a
8744 useful GUI alternative. It seem like a good tool, but is unmaintained
8745 in Debian and got a RC bug keeping it out of Squeeze. Unless that
8746 changes, it will not be an option for Debian Edu based on Squeeze.&lt;/p&gt;

8751 <title>Idea for a change to LDAP schemas allowing DNS and DHCP info to be combined into one object</title>
8752 <link>http://people.skolelinux.org/pere/blog/Idea_for_a_change_to_LDAP_schemas_allowing_DNS_and_DHCP_info_to_be_combined_into_one_object.html</link>

8754 <pubDate>Thu, 24 Jun 2010 00:35:00 +0200</pubDate>
8755 <description>&lt;p&gt;A while back, I
8756 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/Time_for_new__LDAP_schemas_replacing_RFC_2307_.html&quot;&gt;complained
8757 about the fact&lt;/a&gt; that it is not possible with the provided schemas
8758 for storing DNS and DHCP information in LDAP to combine the two sets
8759 of information into one LDAP object representing a computer.&lt;/p&gt;
8760
8761 &lt;p&gt;In the mean time, I discovered that a simple fix would be to make
8762 the dhcpHost object class auxiliary, to allow it to be combined with
8763 the dNSDomain object class, and thus forming one object for one
8764 computer when storing both DHCP and DNS information in LDAP.&lt;/p&gt;
8765
8766 &lt;p&gt;If I understand this correctly, it is not safe to do this change
8767 without also changing the assigned number for the object class, and I
8768 do not know enough about LDAP schema design to do that properly for
8769 Debian Edu.&lt;/p&gt;
8770
8771 &lt;p&gt;Anyway, for future reference, this is how I believe we could change
8772 the
8773 &lt;a href=&quot;http://tools.ietf.org/html/draft-ietf-dhc-ldap-schema-00&quot;&gt;DHCP
8774 schema&lt;/a&gt; to solve at least part of the problem with the LDAP schemas
8775 available today from IETF.&lt;/p&gt;

8791 &lt;p&gt;I very much welcome clues on how to do this properly for Debian

8801 <title>Lenny-&gt;Squeeze upgrades, removals by apt and aptitude</title>

8805 <description>&lt;p&gt;My
8806 &lt;a href=&quot;http://people.skolelinux.org/pere/blog/Automatic_upgrade_testing_from_Lenny_to_Squeeze.html&quot;&gt;testing
8807 of Debian upgrades&lt;/a&gt; from Lenny to Squeeze continues, and I&#39;ve
8808 finally made the upgrade logs available from
8809 &lt;a href=&quot;http://people.skolelinux.org/pere/debian-upgrade-testing/&quot;&gt;http://people.skolelinux.org/pere/debian-upgrade-testing/&lt;/a&gt;.
8810 I am now testing dist-upgrade of Gnome and KDE in a chroot using both
8811 apt and aptitude, and found their differences interesting. This time
8812 I will only focus on their removal plans.&lt;/p&gt;
8813
8814 &lt;p&gt;After installing a Gnome desktop and the laptop task, apt-get wants
8815 to remove 72 packages when dist-upgrading from Lenny to Squeeze. The
8816 surprising part is that it want to remove xorg and all
8817 xserver-xorg-video* drivers. Clearly not a good choice, but I am not
8818 sure why. When asking aptitude to do the same, it want to remove 129
8819 packages, but most of them are library packages I suspect are no
8820 longer needed. Both of them want to remove bluetooth packages, which
8821 I do not know. Perhaps these bluetooth packages are obsolete?&lt;/p&gt;
8822
8823 &lt;p&gt;For KDE, apt-get want to remove 82 packages, among them kdebase
8824 which seem like a bad idea and xorg the same way as with Gnome. Asking
8825 aptitude for the same, it wants to remove 192 packages, none which are
8826 too surprising.&lt;/p&gt;
8827
8828 &lt;p&gt;I guess the removal of xorg during upgrades should be investigated
8829 and avoided, and perhaps others as well. Here are the complete list
8830 of planned removals. The complete logs is available from the URL
8831 above. Note if you want to repeat these tests, that the upgrade test
8832 for kde+apt-get hung in the tasksel setup because of dpkg asking
8833 conffile questions. No idea why. I worked around it by using
8834 &#39;&lt;tt&gt;echo &gt;&gt; /proc/&lt;em&gt;pidofdpkg&lt;/em&gt;/fd/0&lt;/tt&gt;&#39; to tell dpkg to
8835 continue.&lt;/p&gt;

8977 <title>Automatic upgrade testing from Lenny to Squeeze</title>
8978 <link>http://people.skolelinux.org/pere/blog/Automatic_upgrade_testing_from_Lenny_to_Squeeze.html</link>
8979 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Automatic_upgrade_testing_from_Lenny_to_Squeeze.html</guid>
8980 <pubDate>Fri, 11 Jun 2010 22:50:00 +0200</pubDate>
8981 <description>&lt;p&gt;The last few days I have done some upgrade testing in Debian, to
8982 see if the upgrade from Lenny to Squeeze will go smoothly. A few bugs
8983 have been discovered and reported in the process
8984 (&lt;a href=&quot;http://bugs.debian.org/585410&quot;&gt;#585410&lt;/a&gt; in nagios3-cgi,
8985 &lt;a href=&quot;http://bugs.debian.org/584879&quot;&gt;#584879&lt;/a&gt; already fixed in
8986 enscript and &lt;a href=&quot;http://bugs.debian.org/584861&quot;&gt;#584861&lt;/a&gt; in
8987 kdebase-workspace-data), and to get a more regular testing going on, I
8988 am working on a script to automate the test.&lt;/p&gt;
8989
8990 &lt;p&gt;The idea is to create a Lenny chroot and use tasksel to install a
8991 Gnome or KDE desktop installation inside the chroot before upgrading
8992 it. To ensure no services are started in the chroot, a policy-rc.d
8993 script is inserted. To make sure tasksel believe it is to install a
8994 desktop on a laptop, the tasksel tests are replaced in the chroot
8995 (only acceptable because this is a throw-away chroot).&lt;/p&gt;
8996
8997 &lt;p&gt;A naive upgrade from Lenny to Squeeze using aptitude dist-upgrade
8998 currently always fail because udev refuses to upgrade with the kernel
8999 in Lenny, so to avoid that problem the file /etc/udev/kernel-upgrade
9000 is created. The bug report
9001 &lt;a href=&quot;http://bugs.debian.org/566000&quot;&gt;#566000&lt;/a&gt; make me suspect
9002 this problem do not trigger in a chroot, but I touch the file anyway
9003 to make sure the upgrade go well. Testing on virtual and real
9004 hardware have failed me because of udev so far, and creating this file
9005 do the trick in such settings anyway. This is a
9006 &lt;a href=&quot;http://www.linuxquestions.org/questions/debian-26/failed-dist-upgrade-due-to-udev-config_sysfs_deprecated-nonsense-804130/&quot;&gt;known
9007 issue&lt;/a&gt; and the current udev behaviour is intended by the udev
9008 maintainer because he lack the resources to rewrite udev to keep
9009 working with old kernels or something like that. I really wish the
9010 udev upstream would keep udev backwards compatible, to avoid such
9011 upgrade problem, but given that they fail to do so, I guess
9012 documenting the way out of this mess is the best option we got for
9013 Debian Squeeze.&lt;/p&gt;
9014
9015 &lt;p&gt;Anyway, back to the task at hand, testing upgrades. This test
9016 script, which I call &lt;tt&gt;upgrade-test&lt;/tt&gt; for now, is doing the
9017 trick:&lt;/p&gt;
9018
9019 &lt;blockquote&gt;&lt;pre&gt;
9020 #!/bin/sh
9021 set -ex
9022
9023 if [ &quot;$1&quot; ] ; then
9024 desktop=$1
9025 else
9026 desktop=gnome
9027 fi
9028
9029 from=lenny
9030 to=squeeze
9031
9032 exec &amp;lt; /dev/null
9033 unset LANG

9035 tmpdir=chroot-$from-upgrade-$to-$desktop
9036 fuser -mv .
9037 debootstrap $from $tmpdir $mirror
9038 chroot $tmpdir aptitude update
9039 cat &gt; $tmpdir/usr/sbin/policy-rc.d &amp;lt;&amp;lt;EOF

9042 EOF
9043 chmod a+rx $tmpdir/usr/sbin/policy-rc.d
9044 exit_cleanup() {
9045 umount $tmpdir/proc
9046 }
9047 mount -t proc proc $tmpdir/proc
9048 # Make sure proc is unmounted also on failure
9049 trap exit_cleanup EXIT INT
9050
9051 chroot $tmpdir aptitude -y install debconf-utils
9052
9053 # Make sure tasksel autoselection trigger. It need the test scripts
9054 # to return the correct answers.
9055 echo tasksel tasksel/desktop multiselect $desktop | \
9056 chroot $tmpdir debconf-set-selections
9057
9058 # Include the desktop and laptop task
9059 for test in desktop laptop ; do
9060 echo &gt; $tmpdir/usr/lib/tasksel/tests/$test &amp;lt;&amp;lt;EOF
9061 #!/bin/sh
9062 exit 2
9063 EOF
9064 chmod a+rx $tmpdir/usr/lib/tasksel/tests/$test
9065 done
9066
9067 DEBIAN_FRONTEND=noninteractive
9068 DEBIAN_PRIORITY=critical
9069 export DEBIAN_FRONTEND DEBIAN_PRIORITY
9070 chroot $tmpdir tasksel --new-install
9071
9072 echo deb $mirror $to main &gt; $tmpdir/etc/apt/sources.list
9073 chroot $tmpdir aptitude update
9074 touch $tmpdir/etc/udev/kernel-upgrade
9075 chroot $tmpdir aptitude -y dist-upgrade
9076 fuser -mv
9077 &lt;/pre&gt;&lt;/blockquote&gt;
9078
9079 &lt;p&gt;I suspect it would be useful to test upgrades with both apt-get and
9080 with aptitude, but I have not had time to look at how they behave
9081 differently so far. I hope to get a cron job running to do the test
9082 regularly and post the result on the web. The Gnome upgrade currently
9083 work, while the KDE upgrade fail because of the bug in
9084 kdebase-workspace-data&lt;/p&gt;
9085
9086 &lt;p&gt;I am not quite sure what kind of extract from the huge upgrade logs
9087 (KDE 167 KiB, Gnome 516 KiB) it make sense to include in this blog
9088 post, so I will refrain from trying. I can report that for Gnome,
9089 aptitude report 760 packages upgraded, 448 newly installed, 129 to
9090 remove and 1 not upgraded and 1024MB need to be downloaded while for
9091 KDE the same numbers are 702 packages upgraded, 507 newly installed,
9092 193 to remove and 0 not upgraded and 1117MB need to be downloaded&lt;/p&gt;
9093
9094 &lt;p&gt;I am very happy to notice that the Gnome desktop + laptop upgrade
9095 is able to migrate to dependency based boot sequencing and parallel
9096 booting without a hitch. Was unsure if there were still bugs with
9097 packages failing to clean up their obsolete init.d script during
9098 upgrades, and no such problem seem to affect the Gnome desktop+laptop
9099 packages.&lt;/p&gt;

9108 <description>&lt;p&gt;Det er merkelig hvordan myter om Skolelinux overlever. En slik
9109 myte er at Skolelinux ikke kan sentraldriftes og ha sentralt plasserte
9110 tjenermaskiner. I siste Computerworld Norge er
9111 &lt;a href=&quot;http://www.idg.no/computerworld/article169432.ece&quot;&gt;IT-sjef
9112 Viggo Billdal i Steinkjer intervjuet&lt;/a&gt;, og forteller uten
9113 blygsel:&lt;/p&gt;
9114
9115 &lt;blockquote&gt;&lt;p&gt;Vi hadde Skolelinux, men det har vi sluttet med. Vi testet
9116 om det lønte seg med Microsoft eller en åpen plattform. Vi fant ut at
9117 Microsoft egentlig var totalt sett bedre egnet. Det var store
9118 driftskostnader med Skolelinux, blant annet på grunn av
9119 desentraliserte servere. Det var komplisert, så vi gikk vekk fra det
9120 og bruker nå bare Windows.&lt;/p&gt;&lt;/blockquote&gt;
9121
9122 &lt;p&gt;En &lt;a
9123 href=&quot;https://init.linpro.no/pipermail/skolelinux.no/bruker/2010-June/009101.html&quot;&gt;rask
9124 sjekk&lt;/a&gt; mot den norske brukerlista i Skolelinuxprosjektet forteller
9125 at Steinkjers forsøk foregikk fram til 2004/2005, og at Røysing skole
9126 i Steinkjer skal ha vært svært fornøyd med Skolelinux men at kommunen
9127 overkjørte skolen og krevde at de gikk over til Windows. Et søk på
9128 nettet sendte meg til
9129 &lt;a href=&quot;http://www.dn.no/multimedia/archive/00090/Dagens_it_nr__18_90826a.pdf&quot;&gt;Dagens
9130 IT nr. 18 2005&lt;/a&gt; hvor en kan lese på side 18:&lt;/p&gt;
9131
9132 &lt;blockquote&gt;&lt;p&gt;Inge Tømmerås ved Røysing skole i Steinkjer kjører ennå
9133 Microsoft, men forteller at kompetanseutfordringen med Skolelinux ikke
9134 var så stor. ­ Jeg syntes Skolelinux var utrolig lett å drifte uten
9135 forkunnskaper. Men man må jo selvsagt ha tilgang på ekstern kompetanse
9136 til installasjoner og maskinvarefeil, sier Tømmerås.&lt;/p&gt;&lt;/blockquote&gt;
9137
9138 &lt;p&gt;Som systemarkitekten bak Skolelinux, kan jeg bare riste på hodet
9139 over påstanden om at Skolelinux krever desentraliserte tjenere.
9140 Skolelinux-arkitekturen er laget for sentralisert drift og plassering
9141 av tjenerne lokalt eller sentralt alt etter behov og nettkapasitet.
9142 Den er modellert på nettverks- og tjenerløsningen som brukes på
9143 Universitetet i Tromsø og Oslo, der jeg jobber med utvikling av
9144 driftstjenester. Dette er det heldigvis noen som har fått med seg, og
9145 jeg er glad for å kunne sitere fra en kommentar på den overnevnte
9146 artikkelen. Min venn og gamle kollega Sturle Sunde forteller der:
9147
9148 &lt;blockquote&gt;
9149 &lt;p&gt;I Flora kommune køyrer vi Skulelinux på skular med alt frå 15 til
9150 meir enn 500 elevar. Dei store skulane har eigen tenar, for det er
9151 mest praktisk. Eg, som er driftsansvarleg for heile nettet, ser
9152 sjeldan dei tenarane fysisk, men at dei står der gjer skulane mindre
9153 avhengige av eksterne linjer som er trege eller dyre. Dei minste
9154 skulane har ikkje eigen tenar. Å bruke sentral tenar er heller ikkje
9155 noko problem. Småskulane klarar seg fint med 1 mbit-linje til ein
9156 sentral tenar eller tenaren på ein større skule.&lt;/p&gt;
9157
9158 &lt;p&gt;Det beste med Skulelinux er halvtjukke klientar. Dei treng ikkje
9159 harddisk og brukar minimalt med ressursar på tenaren fordi dei køyrer
9160 programma lokalt. Eit klasserom med 30 sju-åtte år gamle maskiner har
9161 mykje meir CPU og RAM totalt enn nokon moderne tenar til under
9162 millionen. Det trengst to kommandoar på den sentrale tenaren for å
9163 oppdatere alle klientane, både tynne og halvtjukke. Vi har ingen
9164 problem med diskar som ryk heller, som var eit problem før fordi
9165 elevane sat og sparka i maskinene. Og dei krev lite bandbreidde i
9166 nettet, so det er fullt mogleg å køyre slike på småskular med trege
9167 linjer mot tenaren på ein større skule.&lt;/p&gt;
9168
9169 &lt;p&gt;Flora kommune har nesten 800 Linux-maskiner i sitt skulenett, og
9170 ein person som tek seg av drift av heile nettet, inkludert tenarar,
9171 klientar, operativsystem, programvare, heimekontorløysing og
9172 administrasjon av brukarar.&lt;/p&gt;
9173
9174 &lt;p&gt;No skal det seiast at vi ikkje køyrer rein Skulelinux ut av
9175 boksen. Vi har gjort ein del tilpassingar mot noko Novell-greier som
9176 var der frå før, og som har komplisert installasjonen vår. Etter at
9177 oppsettet var gjort har løysinga vore stabil og kravd minimalt med
9178 arbeid.&lt;/p&gt;
9179 &lt;/blockquote&gt;
9180
9181 &lt;p&gt;Jeg vet at Narvik, Harstad og Oslo er kommuner der Skolelinux
9182 sentraldriftes med sentrale tjenere. Det forteller meg at Steinkjers
9183 IT-sjef neppe bør skylde på Skolelinux-løsningen for sine 5 år gamle
9184 minner.&lt;/p&gt;

9204 <link>http://people.skolelinux.org/pere/blog/Sitesummary_tip__Listing_computer_hardware_models_used_at_site.html</link>
9205 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Sitesummary_tip__Listing_computer_hardware_models_used_at_site.html</guid>
9206 <pubDate>Thu, 3 Jun 2010 12:05:00 +0200</pubDate>
9207 <description>&lt;p&gt;When using sitesummary at a site to track machines, it is possible
9208 to get a list of the machine types in use thanks to the DMI
9209 information extracted from each machine. The script to do so is
9210 included in the sitesummary package, and here is example output from
9211 the Skolelinux build servers:&lt;/p&gt;
9212
9213 &lt;blockquote&gt;&lt;pre&gt;
9214 maintainer:~# /usr/lib/sitesummary/hardware-model-summary
9215 vendor count
9216 Dell Computer Corporation 1
9217 PowerEdge 1750 1
9218 IBM 1
9219 eserver xSeries 345 -[8670M1X]- 1
9220 Intel 2
9221 [no-dmi-info] 3
9222 maintainer:~#
9223 &lt;/pre&gt;&lt;/blockquote&gt;
9224
9225 &lt;p&gt;The quality of the report depend on the quality of the DMI tables
9226 provided in each machine. Here there are Intel machines without model
9227 information listed with Intel as vendor and no model, and virtual Xen
9228 machines listed as [no-dmi-info]. One can add -l as a command line
9229 option to list the individual machines.&lt;/p&gt;
9230
9231 &lt;p&gt;A larger list is
9232 &lt;a href=&quot;http://narvikskolen.no/sitesummary/&quot;&gt;available from the the
9233 city of Narvik&lt;/a&gt;, which uses Skolelinux on all their shools and also
9234 provide the basic sitesummary report publicly. In their report there
9235 are ~1400 machines. I know they use both Ubuntu and Skolelinux on
9236 their machines, and as sitesummary is available in both distributions,
9237 it is trivial to get all of them to report to the same central
9238 collector.&lt;/p&gt;

9246 <pubDate>Tue, 1 Jun 2010 17:05:00 +0200</pubDate>
9247 <description>&lt;p&gt;It is strange to watch how a bug in Debian causing KDM to fail to
9248 start at boot when an NVidia video card is used is handled. The
9249 problem seem to be that the nvidia X.org driver uses a long time to
9250 initialize, and this duration is longer than kdm is configured to
9251 wait.&lt;/p&gt;
9252
9253 &lt;p&gt;I came across two bugs related to this issue,
9254 &lt;a href=&quot;http://bugs.debian.org/583312&quot;&gt;#583312&lt;/a&gt; initially filed
9255 against initscripts and passed on to nvidia-glx when it became obvious
9256 that the nvidia drivers were involved, and
9257 &lt;a href=&quot;http://bugs.debian.org/524751&quot;&gt;#524751&lt;/a&gt; initially filed against
9258 kdm and passed on to src:nvidia-graphics-drivers for unknown reasons.&lt;/p&gt;
9259
9260 &lt;p&gt;To me, it seem that no-one is interested in actually solving the
9261 problem nvidia video card owners experience and make sure the Debian
9262 distribution work out of the box for these users. The nvidia driver
9263 maintainers expect kdm to be set up to wait longer, while kdm expect
9264 the nvidia driver maintainers to fix the driver to start faster, and
9265 while they wait for each other I guess the users end up switching to a
9266 distribution that work for them. I have no idea what the solution is,
9267 but I am pretty sure that waiting for each other is not it.&lt;/p&gt;
9268
9269 &lt;p&gt;I wonder why we end up handling bugs this way.&lt;/p&gt;

9278 <description>&lt;p&gt;A few days ago, parallel booting was enabled in Debian/testing.
9279 The feature seem to hold up pretty well, but three fairly serious
9280 issues are known and should be solved:
9281
9282 &lt;p&gt;&lt;ul&gt;
9283
9284 &lt;li&gt;The wicd package seen to
9285 &lt;a href=&quot;http://bugs.debian.org/508289&quot;&gt;break NFS mounting&lt;/a&gt; and
9286 &lt;a href=&quot;http://bugs.debian.org/581586&quot;&gt;network setup&lt;/a&gt; when
9287 parallel booting is enabled. No idea why, but the wicd maintainer
9288 seem to be on the case.&lt;/li&gt;
9289
9290 &lt;li&gt;The nvidia X driver seem to
9291 &lt;a href=&quot;http://bugs.debian.org/583312&quot;&gt;have a race condition&lt;/a&gt;
9292 triggered more easily when parallel booting is in effect. The
9293 maintainer is on the case.&lt;/li&gt;
9294
9295 &lt;li&gt;The sysv-rc package fail to properly enable dependency based boot
9296 sequencing (the shutdown is broken) when old file-rc users
9297 &lt;a href=&quot;http://bugs.debian.org/575080&quot;&gt;try to switch back&lt;/a&gt; to
9298 sysv-rc. One way to solve it would be for file-rc to create
9299 /etc/init.d/.legacy-bootordering, and another is to try to make
9300 sysv-rc more robust. Will investigate some more and probably upload a
9301 workaround in sysv-rc to help those trying to move from file-rc to
9302 sysv-rc get a working shutdown.&lt;/li&gt;
9303
9304 &lt;/ul&gt;&lt;/p&gt;
9305
9306 &lt;p&gt;All in all not many surprising issues, and all of them seem
9307 solvable before Squeeze is released. In addition to these there are
9308 some packages with bugs in their dependencies and run level settings,
9309 which I expect will be fixed in a reasonable time span.&lt;/p&gt;
9310
9311 &lt;p&gt;If you report any problems with dependencies in init.d scripts to
9312 the BTS, please usertag the report to get it to show up at
9313 &lt;a href=&quot;http://bugs.debian.org/cgi-bin/pkgreport.cgi?users=initscripts-ng-devel@lists.alioth.debian.org&quot;&gt;the
9314 list of usertagged bugs related to this&lt;/a&gt;.&lt;/p&gt;
9315
9316 &lt;p&gt;Update: Correct bug number to file-rc issue.&lt;/p&gt;

9321 <title>More flexible firmware handling in debian-installer</title>
9322 <link>http://people.skolelinux.org/pere/blog/More_flexible_firmware_handling_in_debian_installer.html</link>
9323 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/More_flexible_firmware_handling_in_debian_installer.html</guid>
9324 <pubDate>Sat, 22 May 2010 21:30:00 +0200</pubDate>
9325 <description>&lt;p&gt;After a long break from debian-installer development, I finally
9326 found time today to return to the project. Having to spend less time
9327 working dependency based boot in debian, as it is almost complete now,
9328 definitely helped freeing some time.&lt;/p&gt;
9329
9330 &lt;p&gt;A while back, I ran into a problem while working on Debian Edu. We
9331 include some firmware packages on the Debian Edu CDs, those needed to
9332 get disk and network controllers working. Without having these
9333 firmware packages available during installation, it is impossible to
9334 install Debian Edu on the given machine, and because our target group
9335 are non-technical people, asking them to provide firmware packages on
9336 an external medium is a support pain. Initially, I expected it to be
9337 enough to include the firmware packages on the CD to get
9338 debian-installer to find and use them. This proved to be wrong.
9339 Next, I hoped it was enough to symlink the relevant firmware packages
9340 to some useful location on the CD (tried /cdrom/ and
9341 /cdrom/firmware/). This also proved to not work, and at this point I
9342 found time to look at the debian-installer code to figure out what was
9343 going to work.&lt;/p&gt;
9344
9345 &lt;p&gt;The firmware loading code is in the hw-detect package, and a closer
9346 look revealed that it would only look for firmware packages outside
9347 the installation media, so the CD was never checked for firmware
9348 packages. It would only check USB sticks, floppies and other
9349 &quot;external&quot; media devices. Today I changed it to also look in the
9350 /cdrom/firmware/ directory on the mounted CD or DVD, which should
9351 solve the problem I ran into with Debian edu. I also changed it to
9352 look in /firmware/, to make sure the installer also find firmware
9353 provided in the initrd when booting the installer via PXE, to allow us
9354 to provide the same feature in the PXE setup included in Debian
9355 Edu.&lt;/p&gt;
9356
9357 &lt;p&gt;To make sure firmware deb packages with a license questions are not
9358 activated without asking if the license is accepted, I extended
9359 hw-detect to look for preinst scripts in the firmware packages, and
9360 run these before activating the firmware during installation. The
9361 license question is asked using debconf in the preinst, so this should
9362 solve the issue for the firmware packages I have looked at so far.&lt;/p&gt;
9363
9364 &lt;p&gt;If you want to discuss the details of these features, please
9365 contact us on debian-boot@lists.debian.org.&lt;/p&gt;

9372 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Pieces_of_the_roaming_laptop_puzzle_in_Debian.html</guid>
9373 <pubDate>Wed, 19 May 2010 19:00:00 +0200</pubDate>
9374 <description>&lt;p&gt;Today, the last piece of the puzzle for roaming laptops in Debian
9375 Edu finally entered the Debian archive. Today, the new
9376 &lt;a href=&quot;http://packages.qa.debian.org/libp/libpam-mklocaluser.html&quot;&gt;libpam-mklocaluser&lt;/a&gt;
9377 package was accepted. Two days ago, two other pieces was accepted
9378 into unstable. The
9379 &lt;a href=&quot;http://packages.qa.debian.org/p/pam-python.html&quot;&gt;pam-python&lt;/a&gt;
9380 package needed by libpam-mklocaluser, and the
9381 &lt;a href=&quot;http://packages.qa.debian.org/s/sssd.html&quot;&gt;sssd&lt;/a&gt; package
9382 passed NEW on Monday. In addition, the
9383 &lt;a href=&quot;http://packages.qa.debian.org/libp/libpam-ccreds.html&quot;&gt;libpam-ccreds&lt;/a&gt;
9384 package we need is in experimental (version 10-4) since Saturday, and
9385 hopefully will be moved to unstable soon.&lt;/p&gt;
9386
9387 &lt;p&gt;This collection of packages allow for two different setups for
9388 roaming laptops. The traditional setup would be using libpam-ccreds,
9389 nscd and libpam-mklocaluser with LDAP or Kerberos authentication,
9390 which should work out of the box if the configuration changes proposed
9391 for nscd in &lt;a href=&quot;http://bugs.debian.org/485282&quot;&gt;BTS report
9392 #485282&lt;/a&gt; is implemented. The alternative setup is to use sssd with
9393 libpam-mklocaluser to connect to LDAP or Kerberos and let sssd take
9394 care of the caching of passwords and group information.&lt;/p&gt;
9395
9396 &lt;p&gt;I have so far been unable to get sssd to work with the LDAP server
9397 at the University, but suspect the issue is some SSL/GnuTLS related
9398 problem with the server certificate. I plan to update the Debian
9399 package to version 1.2, which is scheduled for next week, and hope to
9400 find time to make sure the next release will include both the
9401 Debian/Ubuntu specific patches. Upstream is friendly and responsive,
9402 and I am sure we will find a good solution.&lt;/p&gt;
9403
9404 &lt;p&gt;The idea is to set up the roaming laptops to authenticate using
9405 LDAP or Kerberos and create a local user with home directory in /home/
9406 when a usre in LDAP logs in via KDM or GDM for the first time, and
9407 cache the password for offline checking, as well as caching group
9408 memberhips and other relevant LDAP information. The
9409 libpam-mklocaluser package was created to make sure the local home
9410 directory is in /home/, instead of /site/server/directory/ which would
9411 be the home directory if pam_mkhomedir was used. To avoid confusion
9412 with support requests and configuration, we do not want local laptops
9413 to have users in a path that is used for the same users home directory
9414 on the home directory servers.&lt;/p&gt;
9415
9416 &lt;p&gt;One annoying problem with gdm is that it do not show the PAM
9417 message passed to the user from libpam-mklocaluser when the local user
9418 is created. Instead gdm simply reject the login with some generic
9419 message. The message is shown in kdm, ssh and login, so I guess it is
9420 a bug in gdm. Have not investigated if there is some other message
9421 type that can be used instead to get gdm to also show the message.&lt;/p&gt;

9429 <title>Parallellized boot is now the default in Debian/unstable</title>

9431 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Parallellized_boot_is_now_the_default_in_Debian_unstable.html</guid>

9433 <description>&lt;p&gt;Since this evening, parallel booting is the default in
9434 Debian/unstable for machines using dependency based boot sequencing.
9435 Apparently the testing of concurrent booting has been wider than
9436 expected, if I am to believe the
9437 &lt;a href=&quot;http://lists.debian.org/debian-devel/2010/05/msg00122.html&quot;&gt;input
9438 on debian-devel@&lt;/a&gt;, and I concluded a few days ago to move forward
9439 with the feature this weekend, to give us some time to detect any
9440 remaining problems before Squeeze is frozen. If serious problems are
9441 detected, it is simple to change the default back to sequential boot.
9442 The upload of the new sysvinit package also activate a new upstream
9443 version.&lt;/p&gt;
9444
9445 More information about
9446 &lt;a href=&quot;http://wiki.debian.org/LSBInitScripts/DependencyBasedBoot&quot;&gt;dependency
9447 based boot sequencing&lt;/a&gt; is available from the Debian wiki. It is
9448 currently possible to disable parallel booting when one run into
9449 problems caused by it, by adding this line to /etc/default/rcS:&lt;/p&gt;
9450
9451 &lt;blockquote&gt;&lt;pre&gt;
9452 CONCURRENCY=none
9453 &lt;/pre&gt;&lt;/blockquote&gt;

9455 &lt;p&gt;If you report any problems with dependencies in init.d scripts to
9456 the BTS, please usertag the report to get it to show up at
9457 &lt;a href=&quot;http://bugs.debian.org/cgi-bin/pkgreport.cgi?users=initscripts-ng-devel@lists.alioth.debian.org&quot;&gt;the

9465 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Sitesummary_tip__Listing_MAC_address_of_all_clients.html</guid>
9466 <pubDate>Fri, 14 May 2010 21:10:00 +0200</pubDate>
9467 <description>&lt;p&gt;In the recent Debian Edu versions, the
9468 &lt;a href=&quot;http://wiki.debian.org/DebianEdu/HowTo/SiteSummary&quot;&gt;sitesummary
9469 system&lt;/a&gt; is used to keep track of the machines in the school
9470 network. Each machine will automatically report its status to the
9471 central server after boot and once per night. The network setup is
9472 also reported, and using this information it is possible to get the
9473 MAC address of all network interfaces in the machines. This is useful
9474 to update the DHCP configuration.&lt;/p&gt;
9475
9476 &lt;p&gt;To give some idea how to use sitesummary, here is a one-liner to
9477 ist all MAC addresses of all machines reporting to sitesummary. Run
9478 this on the collector host:&lt;/p&gt;
9479
9480 &lt;blockquote&gt;&lt;pre&gt;
9481 perl -MSiteSummary -e &#39;for_all_hosts(sub { print join(&quot; &quot;, get_macaddresses(shift)), &quot;\n&quot;; });&#39;
9482 &lt;/pre&gt;&lt;/blockquote&gt;
9483
9484 &lt;p&gt;This will list all MAC addresses assosiated with all machine, one
9485 line per machine and with space between the MAC addresses.&lt;/p&gt;
9486
9487 &lt;p&gt;To allow system administrators easier job at adding static DHCP
9488 addresses for hosts, it would be possible to extend this to fetch
9489 machine information from sitesummary and update the DHCP and DNS
9490 tables in LDAP using this information. Such tool is unfortunately not
9491 written yet.&lt;/p&gt;

9496 <title>Forcing new users to change their password on first login</title>

9499 <pubDate>Sun, 2 May 2010 13:47:00 +0200</pubDate>
9500 <description>&lt;p&gt;One interesting feature in Active Directory, is the ability to
9501 create a new user with an expired password, and thus force the user to
9502 change the password on the first login attempt.&lt;/p&gt;
9503
9504 &lt;p&gt;I&#39;m not quite sure how to do that with the LDAP setup in Debian
9505 Edu, but did some initial testing with a local account. The account
9506 and password aging information is available in /etc/shadow, but
9507 unfortunately, it is not possible to specify an expiration time for
9508 passwords, only a maximum age for passwords.&lt;/p&gt;
9509
9510 &lt;p&gt;A freshly created account (using adduser test) will have these
9511 settings in /etc/shadow:&lt;/p&gt;
9512
9513 &lt;blockquote&gt;&lt;pre&gt;
9514 root@tjener:~# chage -l test
9515 Last password change : May 02, 2010
9516 Password expires : never
9517 Password inactive : never
9518 Account expires : never
9519 Minimum number of days between password change : 0
9520 Maximum number of days between password change : 99999
9521 Number of days of warning before password expires : 7
9522 root@tjener:~#
9523 &lt;/pre&gt;&lt;/blockquote&gt;
9524
9525 &lt;p&gt;The only way I could come up with to create a user with an expired
9526 account, is to change the date of the last password change to the
9527 lowest value possible (January 1th 1970), and the maximum password age
9528 to the difference in days between that date and today. To make it
9529 simple, I went for 30 years (30 * 365 = 10950) and January 2th (to
9530 avoid testing if 0 is a valid value).&lt;/p&gt;
9531
9532 &lt;p&gt;After using these commands to set it up, it seem to work as
9533 intended:&lt;/p&gt;
9534
9535 &lt;blockquote&gt;&lt;pre&gt;
9536 root@tjener:~# chage -d 1 test; chage -M 10950 test
9537 root@tjener:~# chage -l test
9538 Last password change : Jan 02, 1970
9539 Password expires : never
9540 Password inactive : never
9541 Account expires : never
9542 Minimum number of days between password change : 0
9543 Maximum number of days between password change : 10950
9544 Number of days of warning before password expires : 7
9545 root@tjener:~#
9546 &lt;/pre&gt;&lt;/blockquote&gt;
9547
9548 &lt;p&gt;So far I have tested this with ssh and console, and kdm (in
9549 Squeeze) login, and all ask for a new password before login in the
9550 user (with ssh, I was thrown out and had to log in again).&lt;/p&gt;
9551
9552 &lt;p&gt;Perhaps we should set up something similar for Debian Edu, to make
9553 sure only the user itself have the account password?&lt;/p&gt;
9554
9555 &lt;p&gt;If you want to comment on or help out with implementing this for
9556 Debian Edu, please contact us on debian-edu@lists.debian.org.&lt;/p&gt;
9557
9558 &lt;p&gt;Update 2010-05-02 17:20: Paul Tötterman tells me on IRC that the
9559 shadow(8) page in Debian/testing now state that setting the date of
9560 last password change to zero (0) will force the password to be changed
9561 on the first login. This was not mentioned in the manual in Lenny, so
9562 I did not notice this in my initial testing. I have tested it on
9563 Squeeze, and &#39;&lt;tt&gt;chage -d 0 username&lt;/tt&gt;&#39; do work there. I have not
9564 tested it on Lenny yet.&lt;/p&gt;
9565
9566 &lt;p&gt;Update 2010-05-02-19:05: Jim Paris tells me via email that an
9567 equivalent command to expire a password is &#39;&lt;tt&gt;passwd -e
9568 username&lt;/tt&gt;&#39;, which insert zero into the date of the last password
9569 change.&lt;/p&gt;

9574 <title>Thoughts on roaming laptop setup for Debian Edu</title>
9575 <link>http://people.skolelinux.org/pere/blog/Thoughts_on_roaming_laptop_setup_for_Debian_Edu.html</link>
9576 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Thoughts_on_roaming_laptop_setup_for_Debian_Edu.html</guid>
9577 <pubDate>Wed, 28 Apr 2010 20:40:00 +0200</pubDate>
9578 <description>&lt;p&gt;For some years now, I have wondered how we should handle laptops in
9579 Debian Edu. The Debian Edu infrastructure is mostly designed to
9580 handle stationary computers, and less suited for computers that come
9581 and go.&lt;/p&gt;
9582
9583 &lt;p&gt;Now I finally believe I have an sensible idea on how to adjust
9584 Debian Edu for laptops, by introducing a new profile for them, for
9585 example called Roaming Workstations. Here are my thought on this.
9586 The setup would consist of the following:&lt;/p&gt;
9587
9588 &lt;ul&gt;
9589
9590 &lt;li&gt;During installation, the user name of the owner / primary user of
9591 the laptop is requested and a local home directory is set up for
9592 the user, with uid and gid information fetched from the LDAP
9593 server. This allow the user to work also when offline. The
9594 central home directory can be available in a subdirectory on
9595 request, for example mounted via CIFS. It could be mounted
9596 automatically when a user log in while on the Debian Edu network,
9597 and unmounted when the machine is taken away (network down,
9598 hibernate, etc), it can be set up to do automatic mounting on
9599 request (using autofs), or perhaps some GUI button on the desktop
9600 can be used to access it when needed. Perhaps it is enough to use
9601 the fish protocol in KDE?&lt;/li&gt;
9602
9603 &lt;li&gt;Password checking is set up to use LDAP or Kerberos
9604 authentication when the machine is on the Debian Edu network, and
9605 to cache the password for offline checking when the machine unable
9606 to reach the LDAP or Kerberos server. This can be done using
9607 &lt;a href=&quot;http://www.padl.com/OSS/pam_ccreds.html&quot;&gt;libpam-ccreds&lt;/a&gt;
9608 or the Fedora developed
9609 &lt;a href=&quot;https://fedoraproject.org/wiki/Features/SSSD&quot;&gt;System
9610 Security Services Daemon&lt;/a&gt; packages.&lt;/li&gt;
9611
9612 &lt;li&gt;File synchronisation with the central home directory is set up
9613 using a shared directory in both the local and the central home
9614 directory, using unison.&lt;/li&gt;
9615
9616 &lt;li&gt;Printing should be set up to print to all printers broadcasting
9617 their existence on the local network, and should then work out of
9618 the box with CUPS. For sites needing accurate printer quotas, some
9619 system with Kerberos authentication or printing via ssh could be
9620 implemented.&lt;/li&gt;
9621
9622 &lt;li&gt;For users that should have local root access to their laptop,
9623 sudo should be used to allow this to the local user.&lt;/li&gt;
9624
9625 &lt;li&gt;It would be nice if user and group information from LDAP is
9626 cached on the client, but given that there are entries for the
9627 local user and primary group in /etc/, it should not be needed.&lt;/li&gt;
9628
9629 &lt;/ul&gt;
9630
9631 &lt;p&gt;I believe all the pieces to implement this are in Debian/testing at
9632 the moment. If we work quickly, we should be able to get this ready
9633 in time for the Squeeze release to freeze. Some of the pieces need
9634 tweaking, like libpam-ccreds should get support for pam-auth-update
9635 (&lt;a href=&quot;http://bugs.debian.org/566718&quot;&gt;#566718&lt;/a&gt;) and nslcd (or
9636 perhaps debian-edu-config) should get some integration code to stop
9637 its daemon when the LDAP server is unavailable to avoid long timeouts
9638 when disconnected from the net. If we get Kerberos enabled, we need
9639 to make sure we avoid long timeouts there too.&lt;/p&gt;
9640
9641 &lt;p&gt;If you want to help out with implementing this for Debian Edu,
9642 please contact us on debian-edu@lists.debian.org.&lt;/p&gt;

9651 <description>&lt;p&gt;&lt;a href=&quot;http://www.nuug.no/aktiviteter/20100413-kerberos/&quot;&gt;Yesterdays
9652 NUUG presentation&lt;/a&gt; about Kerberos was inspiring, and reminded me
9653 about the need to start using Kerberos in Skolelinux. Setting up a
9654 Kerberos server seem to be straight forward, and if we get this in
9655 place a long time before the Squeeze version of Debian freezes, we
9656 have a chance to migrate Skolelinux away from NFSv3 for the home
9657 directories, and over to an architecture where the infrastructure do
9658 not have to trust IP addresses and machines, and instead can trust
9659 users and cryptographic keys instead.&lt;/p&gt;
9660
9661 &lt;p&gt;A challenge will be integration and administration. Is there a
9662 Kerberos implementation for Debian where one can control the
9663 administration access in Kerberos using LDAP groups? With it, the
9664 school administration will have to maintain access control using flat
9665 files on the main server, which give a huge potential for errors.&lt;/p&gt;
9666
9667 &lt;p&gt;A related question I would like to know is how well Kerberos and
9668 pam-ccreds (offline password check) work together. Anyone know?&lt;/p&gt;
9669
9670 &lt;p&gt;Next step will be to use Kerberos for access control in Lwat and
9671 Nagios. I have no idea how much work that will be to implement. We
9672 would also need to document how to integrate with Windows AD, as such
9673 shared network will require two Kerberos realms that need to cooperate
9674 to work properly.&lt;/p&gt;
9675
9676 &lt;p&gt;I believe a good start would be to start using Kerberos on the
9677 skolelinux.no machines, and this way get ourselves experience with
9678 configuration and integration. A natural starting point would be
9679 setting up ldap.skolelinux.no as the Kerberos server, and migrate the
9680 rest of the machines from PAM via LDAP to PAM via Kerberos one at the
9681 time.&lt;/p&gt;
9682
9683 &lt;p&gt;If you would like to contribute to get this working in Skolelinux,
9684 I recommend you to see the video recording from yesterdays NUUG
9685 presentation, and start using Kerberos at home. The video show show
9686 up in a few days.&lt;/p&gt;

9695 <description>&lt;p&gt;6 years ago, as part of the Debian Edu development I am involved
9696 in, I asked for a hook in the kdm and gdm setup to run scripts as root
9697 when the user log out. A bug was submitted against the xfree86-common
9698 package in 2004 (&lt;a href=&quot;http://bugs.debian.org/230422&quot;&gt;#230422&lt;/a&gt;),
9699 and revisited every time Debian Edu was working on a new release.
9700 Today, this finally paid off.&lt;/p&gt;
9701
9702 &lt;p&gt;The framework for this feature was today commited to the git
9703 repositry for the xorg package, and the git repository for xdm has
9704 been updated to use this framework. Next on my agenda is to make sure
9705 kdm and gdm also add code to use this framework.&lt;/p&gt;
9706
9707 &lt;p&gt;In Debian Edu, we want to ability to run commands as root when the
9708 user log out, to get rid of runaway processes and do general cleanup
9709 after a user. With this framework in place, we finally can do that in
9710 a generic way that work with all display managers using this
9711 framework. My goal is to get all display managers in Debian use it,
9712 similar to how they use the Xsession.d framework today.&lt;p&gt;

9721 <description>&lt;p&gt;On Tuesday, the Debian/Lenny based version of
9722 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt; was finally
9723 shipped. This was a major leap forward for the project, and I am very
9724 pleased that we finally got the release wrapped up. Work on the first
9725 point release starts imediately, as we plan to get that one out a
9726 month after the major release, to include all fixes for bugs we found
9727 and fixed too late in the release process to include last Tuesday.&lt;/p&gt;
9728
9729 &lt;p&gt;Perhaps it even is time for some partying?&lt;/p&gt;
9730
9731 &lt;p&gt;After this first point release, my plan is to focus again on the
9732 next major release, based on Squeeze. We will try to get as many of
9733 the fixes we need into the official Debian packages before the freeze,
9734 and have just a few weeks or months to make it happen.&lt;/p&gt;

9739 <title>Automatic Munin and Nagios configuration</title>
9740 <link>http://people.skolelinux.org/pere/blog/Automatic_Munin_and_Nagios_configuration.html</link>
9741 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Automatic_Munin_and_Nagios_configuration.html</guid>
9742 <pubDate>Wed, 27 Jan 2010 15:15:00 +0100</pubDate>
9743 <description>&lt;p&gt;One of the new features in the next Debian/Lenny based release of
9744 Debian Edu/Skolelinux, which is scheduled for release in the next few
9745 days, is automatic configuration of the service monitoring system
9746 Nagios. The previous release had automatic configuration of trend
9747 analysis using Munin, and this Lenny based release take that a step
9748 further.&lt;/p&gt;
9749
9750 &lt;p&gt;When installing a Debian Edu Main-server, it is automatically
9751 configured as a Munin and Nagios server. In addition, it is
9752 configured to be a server for the
9753 &lt;a href=&quot;http://wiki.debian.org/DebianEdu/HowTo/SiteSummary&quot;&gt;SiteSummary
9754 system&lt;/a&gt; I have written for use in Debian Edu. The SiteSummary
9755 system is inspired by a system used by the University of Oslo where I
9756 work. In short, the system provide a centralised collector of
9757 information about the computers on the network, and a client on each
9758 computer submitting information to this collector. This allow for
9759 automatic information on which packages are installed on each machine,
9760 which kernel the machines are using, what kind of configuration the
9761 packages got etc. This also allow us to automatically generate Munin
9762 and Nagios configuration.&lt;/p&gt;
9763
9764 &lt;p&gt;All computers reporting to the sitesummary collector with the
9765 munin-node package installed is automatically enabled as a Munin
9766 client and graphs from the statistics collected from that machine show
9767 up automatically on http://www/munin/ on the Main-server.&lt;/p&gt;
9768
9769 &lt;p&gt;All non-laptop computers reporting to the sitesummary collector are
9770 automatically monitored for network presence (ping and any network
9771 services detected). In addition, all computers (also laptops) with
9772 the nagios-nrpe-server package installed and configured the way
9773 sitesummary would configure it, are monitored for full disks, software
9774 raid status, swap free and other checks that need to run locally on
9775 the machine.&lt;/p&gt;
9776
9777 &lt;p&gt;The result is that the administrator on a school using Debian Edu
9778 based on Lenny will be able to check the health of his installation
9779 with one look at the Nagios settings, without having to spend any time
9780 keeping the Nagios configuration up-to-date.&lt;/p&gt;
9781
9782 &lt;p&gt;The only configuration one need to do to get Nagios up and running
9783 is to set the password used to get access via HTTP. The system
9784 administrator need to run &quot;&lt;tt&gt;htpasswd /etc/nagios3/htpasswd.users
9785 nagiosadmin&lt;/tt&gt;&quot; to create a nagiosadmin user and set a password for
9786 it to be able to log into the Nagios web pages. After that,
9787 everything is taken care of.&lt;/p&gt;

9796 <description>&lt;p&gt;De færreste er klar over at Skolelinux-prosjektet kom som et resultat
9797 av en avgjørelse på årsmøtet i
9798 &lt;a href=&quot;http://www.nuug.no/&quot;&gt;NUUG&lt;/a&gt; i 2000-06-29, der Håkon Wium
9799 Lie, da varamedlem i styret, tok på seg oppdraget om å starte et
9800 initiativ kalt &quot;Teach the Teacher&quot;, som skulle være et initiativ for
9801 å få fri programvare og unix-lignende operativsystemer inn i Skolen.
9802 Tanken var at en måtte starte med lærerne for at ungene skulle få
9803 mulighet til å møte en bedre IT-hverdag. Jeg var tilstede på
9804 møtet, og hadde sans for ideen, men intet skjedde. På vårparten
9805 2001 ble det arrangert en demonstrasjon i anledning at First Tuesday
9806 hadde invitert Microsoft til et møte for å fortelle om fremtidens
9807 Internet. Dette provoserte endel av oss, og EFN og NUUG tok initiativ
9808 til å arrangere
9809 &lt;a href=&quot;http://www.digi.no/60982/first-tuesday-mote-med-microsoft-protest&quot;&gt;en
9810 demonstrasjon utenfor lokalene 2001-05-21&lt;/a&gt;. Blant de som sto bak
9811 demonstrasjonen var Vidar Bakke fra NUUG og Håkon W. Lie fra EFN.
9812 Etter demonstrasjonen arrangerte Håkon en fest hjemme hos seg der alle
9813 som hadde vært aktive i demonstrasjonsplanlegging og gjennomføringen
9814 deltok. Før festen var jeg blitt lei av å vente på at Håkon skulle ta
9815 initiativ til &quot;Teach the Teacher&quot;, og for å forsøke å få litt fremgang
9816 besteme jeg meg for å benytte anledningen hos Håkon til å snakke om
9817 behovet for å hjelpe skolene i gang med bedre datasystemer bestående
9818 av fri programvare og unix-lignende operativsystemer. Flere var
9819 interessert, og Knut Yrvin tenkte på ideen. Han
9820 &lt;a href=&quot;http://developer.skolelinux.no/brev/2001-06-28-invitasjon-skolelinux.txt&quot;&gt;ropte
9821 sammen&lt;/a&gt; til et stiftelsesmøte i prosjektet i sin arbeidsgivers
9822 Objectwares lokaler ved Ullevål stadion 2001-07-02, og jeg ble med.
9823 Resten er historie. :)&lt;/p&gt;

9832 <description>&lt;p&gt;Under helgens utviklersamling i
9833 &lt;a href=&quot;http://www.skolelinux.no/&quot;&gt;Skolelinux&lt;/a&gt; fikk jeg endelig
9834 satt meg ned sammen med Ronny Aasen i styret for å få et webbasert
9835 medlemsregister tilbake på plass for foreningen som passer på
9836 skolelinuxprosjektet. Etter flere års knot og problemer, er nå
9837 memberdb satt opp og klart til bruk. Import av det gamle
9838 medlemsregisteret har vist seg vanskelig, så alle medlemmer bes om å
9839 registrere seg på nytt. Hvis du støtter FRiSKs formål så er du
9840 hjertelig velkommen til
9841 &lt;a href=&quot;http://medlem.friprogramvareiskolen.no/&quot;&gt;å melde deg
9842 inn&lt;/a&gt;. Formålet lyder:&lt;/p&gt;
9843
9844 &lt;blockquote&gt;Linux i skolen skal tilrettelegge for og informere om bruk
9845 av fri programvare, i henhold til Debian Free Software Guidelines av
9846 2002-02-03, i den norske skolen, slik som f.eks. Linux og
9847 GNU.&lt;/blockquote&gt;

9856 <description>&lt;p&gt;I&#39;m sitting on the train going home from this weekends Debian
9857 Edu/Skolelinux development gathering. I got a bit done tuning the
9858 desktop, and looked into the dynamic service location protocol
9859 implementation avahi. It look like it could be useful for us. Almost
9860 30 people participated, and I believe it was a great environment to
9861 get to know the Skolelinux system. Walter Bender, involved in the
9862 development of the Sugar educational platform, presented his stuff and
9863 also helped me improve my OLPC installation. He also showed me that
9864 his Turtle Art application can be used in standalone mode, and we
9865 agreed that I would help getting it packaged for Debian. As a
9866 standalone application it would be great for Debian Edu. We also
9867 tried to get the video conferencing working with two OLPCs, but that
9868 proved to be too hard for us. The application seem to need more work
9869 before it is ready for me. I look forward to getting home and relax
9870 now. :)&lt;/p&gt;

9875 <title>Time for new LDAP schemas replacing RFC 2307?</title>
9876 <link>http://people.skolelinux.org/pere/blog/Time_for_new__LDAP_schemas_replacing_RFC_2307_.html</link>
9877 <guid isPermaLink="true">http://people.skolelinux.org/pere/blog/Time_for_new__LDAP_schemas_replacing_RFC_2307_.html</guid>
9878 <pubDate>Sun, 29 Mar 2009 20:30:00 +0200</pubDate>
9879 <description>&lt;p&gt;The state of standardized LDAP schemas on Linux is far from
9880 optimal. There is RFC 2307 documenting one way to store NIS maps in
9881 LDAP, and a modified version of this normally called RFC 2307bis, with
9882 some modifications to be compatible with Active Directory. The RFC
9883 specification handle the content of a lot of system databases, but do
9884 not handle DNS zones and DHCP configuration.&lt;/p&gt;
9885
9886 &lt;p&gt;In &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Debian Edu/Skolelinux&lt;/a&gt;,
9887 we would like to store information about users, SMB clients/hosts,
9888 filegroups, netgroups (users and hosts), DHCP and DNS configuration,
9889 and LTSP configuration in LDAP. These objects have a lot in common,
9890 but with the current LDAP schemas it is not possible to have one
9891 object per entity. For example, one need to have at least three LDAP
9892 objects for a given computer, one with the SMB related stuff, one with
9893 DNS information and another with DHCP information. The schemas
9894 provided for DNS and DHCP are impossible to combine into one LDAP
9895 object. In addition, it is impossible to implement quick queries for
9896 netgroup membership, because of the way NIS triples are implemented.
9897 It just do not scale. I believe it is time for a few RFC
9898 specifications to cleam up this mess.&lt;/p&gt;
9899
9900 &lt;p&gt;I would like to have one LDAP object representing each computer in
9901 the network, and this object can then keep the SMB (ie host key), DHCP
9902 (mac address/name) and DNS (name/IP address) settings in one place.
9903 It need to be efficently stored to make sure it scale well.&lt;/p&gt;
9904
9905 &lt;p&gt;I would also like to have a quick way to map from a user or
9906 computer and to the net group this user or computer is a member.&lt;/p&gt;
9907
9908 &lt;p&gt;Active Directory have done a better job than unix heads like myself
9909 in this regard, and the unix side need to catch up. Time to start a
9910 new IETF work group?&lt;/p&gt;

9939 <description>&lt;p&gt;Etter flere års mislykkede forsøk på å skrive om byggesystemet for
9940 &lt;a href=&quot;http://no.speling.org/&quot;&gt;den norske stavekontrollen for bokmål
9941 og nynorsk&lt;/a&gt; til å ikke bruke bindestrek som ordskillemarkør, lyktes jeg
9942 endelig første juledag. Bruken av bindestrek som ordskillemarkør har
9943 gjort det umulig å få med ord med bindestrek i
9944 stavekontrolldatagrunnlaget, slik at ord som e-post og CD-spiller ikke
9945 kunne godtas av stavekontrollen. Hadde litt tid til overs å bruke på
9946 stavekontrollen, og satte meg ned med to kopier av byggsystemet og en
9947 liten testdatafil, og byttet ut - med = på utvalgte steder i
9948 byggsystemet og datafilen helt til jeg fikk samme resultat med det
9949 gamle og det nye byggsystemet. Dette tror jeg var forsøk 4, der de
9950 foregående har feilet uten at jeg klarte å forstå hvorfor. Det sier
9951 kanskje litt om kompleksiteten i det originale byggsystemet som Rune
9952 Kleveland laget i sin tid.&lt;/p&gt;
9953
9954 &lt;p&gt;Etter å ha endret byggsystemet, var neste steg å importere ordene
9955 med bindestrek. Vi har en rekke slike i databasene for
9956 &lt;a href=&quot;http://tyge.sslug.dk/~korsvoll/nb.speling.org/htdocs/&quot;&gt;bokmål&lt;/a&gt;
9957 og
9958 &lt;a href=&quot;http://tyge.sslug.dk/~korsvoll/nn.speling.org/htdocs/&quot;&gt;nynorsk&lt;/a&gt;
9959 for korrektur av datagrunnlaget for stavekontrollen, og etter importen
9960 skulle nå 10350 nye ord bli godkjent som korrekt stavede ord av
9961 stavekontrollen.&lt;/p&gt;

9970 <description>&lt;p&gt;This weekend we had a small developer gathering for Debian Edu in
9971 Oslo. Most of Saturday was used for the general assemly for the
9972 member organization, but the rest of the weekend I used to tune the
9973 LTSP installation. LTSP now work out of the box on the 10-network.
9974 Acer Aspire One proved to be a very nice thin client, with both
9975 screen, mouse and keybard in a small box. Was working on getting the
9976 diskless workstation setup configured out of the box, but did not
9977 finish it before the weekend was up.&lt;/p&gt;
9978
9979 &lt;p&gt;Did not find time to look at the 4 VGA cards in one box we got from
9980 the Brazilian group, so that will have to wait for the next
9981 development gathering. Would love to have the Debian Edu installer
9982 automatically detect and configure a multiseat setup when it find one
9983 of these cards.&lt;/p&gt;

9992 <description>&lt;p&gt;Recently I have spent some time evaluating the multimedia browser
9993 plugins available in Debian Lenny, to see which one we should use by
9994 default in Debian Edu. We need an embedded video playing plugin with
9995 control buttons to pause or stop the video, and capable of streaming
9996 all the multimedia content available on the web. The test results and
9997 notes are available on
9998 &lt;a href=&quot;http://wiki.debian.org/DebianEdu/BrowserMultimedia&quot;&gt;the
9999 Debian wiki&lt;/a&gt;. I was surprised how few of the plugins are able to
10000 fill this need. My personal video player favorite, VLC, has a really
10001 bad plugin which fail on a lot of the test pages. A lot of the MIME
10002 types I would expect to work with any free software player (like
10003 video/ogg), just do not work. And simple formats like the
10004 audio/x-mplegurl format (m3u playlists), just isn&#39;t supported by the
10005 totem and vlc plugins. I hope the situation will improve soon. No
10006 wonder sites use the proprietary Adobe flash to play video.&lt;/p&gt;
10007
10008 &lt;p&gt;For Lenny, we seem to end up with the mplayer plugin. It seem to
10009 be the only one fitting our needs. :/&lt;/p&gt;
