><a href=

">Debian Edu, also known as
47 Skolelinux
</a
>, is a Linux distribution based on Debian providing an
48 out-of-the box environment of a completely configured school
49 network. Immediately after installation a school server running all
50 services needed for a school network is set up just waiting for users
51 and machines being added via GOsa², a comfortable Web-UI. A netbooting
52 environment is prepared using PXE, so after initial installation of
53 the main server from CD, DVD or USB stick all other machines can be
54 installed via the network. The provided school server provides LDAP
55 database and Kerberos authentication service, centralized home
56 directories, DHCP server, web proxy and many other services. The
58 <a href=
"http://people.skolelinux.org/pere/blog/Educational_applications_included_in_Debian_Edu___Skolelinux__the_screenshot_collection____.html
">more
59 than
60 educational software packages
</a
> and more are available from
60 the Debian archive, and schools can choose between KDE, Gnome, LXDE
61 and Xfce desktop environment.
</p
>
63 <p
>This is the fourth test release based on Debian Wheezy. Basically
64 this is an updated and slightly improved version compared to the
65 Squeeze release.
</p
>
67 <p
><strong
>Software updates
</strong
></p
>
69 <li
>Dropped ispell dictionaries from our default installation.
</li
>
70 <li
>Dropped menu-xdg from the KDE desktop option, to drop the Debian
71 submenu. It was not included with Gnome, LXDE or Xfce, so this
72 brings KDE in line with the others.
</li
>
73 <li
>Dropped xdrawchem, xjig and xsok from our default installation as
74 they don
't have a desktop menu entry and thus won
't show up in the
75 menu now that menu-xdg was removed.
</li
>
76 <li
>Removed the killer system to kill left behind processes on
77 multi-user machines, as it was no longer able to understand when a
78 X display was in use and killed the processes of the active users
80 <li
>Dropped the golearn (from goplay) package as the debtags in wheezy
81 are too few to make the package useful.
</li
>
83 <p
><strong
>Other changes
</strong
></p
>
85 <li
>Updated artwork matching http://wiki.debian.org/DebianArt/Themes/Joy
86 <li
>Multi-arch i386/amd64 USB stick ISO available.
</li
>
87 <li
>Got rid of ispell/wordlist related debconf questions that showed
88 up for some language options.
</li
>
89 <li
>Switched to using http.debian.net as APT source by default.
</li
>
90 <li
>Fixed proxy configuration on Main Server installations.
</li
>
91 <li
>Changed LTSP setup to ask dpkg to use force-unsafe-io the same way
92 d-i is doing it.
</li
>
93 <li
>Made sure root and user passwords were not left behind in the
94 debconf database after installation on Main Server installations.
</li
>
95 <li
>Made Roaming Workstation dynamic setup more robust and added draft
96 script setup-ad-client to hook a Roaming Workstation up to a
97 Active Directory server instead of a Debian Edu Main Server.
</li
>
98 <li
>Update system to install needed firmware packages during
99 installation, to work properly in Wheezy.
</li
>
100 <li
>Update system to handle hardware quirks (debian-edu-hwsetup).
</li
>
101 <li
>Corrected PXE installation setup to properly pass selected desktop
102 and keymap settings to PXE installation clients.
</li
>
103 <li
>LTSP diskless workstations use sshfs by default, allowing them to
104 work without adding them to DNS and NIS netgroups for NFS access.
</li

106 <p

>In the
<a href=
"http://www.skolelinux.org/
">Debian Edu /
146 Skolelinux
</a
> project, we include a post-installation test suite,
147 which check that services are running, working, and return the
148 expected results. It runs automatically just after the first boot on
149 test installations (using test ISOs), but not on production
150 installations (using non-test ISOs). It test that the LDAP service is
151 operating, Kerberos is responding, DNS is replying, file systems are
152 online resizable, etc, etc. And it check that the PXE service is
153 configured, which is the topic of this post.
</p
>
155 <p
>The last week I
've fixed the DVD and USB stick ISOs for our Debian
156 Edu Wheezy release. These ISOs are supposed to be able to install a
157 complete system without any Internet connection, but for that to
158 happen all the needed packages need to be on them. Thanks to our test
159 suite, I discovered that we had forgotten to adjust our PXE setup to
160 cope with the new names and paths used by the netboot d-i packages.
161 When Internet connectivity was available, the installer fall back to
162 using wget to fetch d-i boot images, but when offline it require
163 working packages to get it working. And ad the packages changed name
164 from debian-installer-
6.0-netboot-$arch to
165 debian-installer-
7.0-netboot-$arch, we no longer pulled in the
166 packages during installation. Without our test suite, I suspect we
167 would never have discovered this before release. Now it is fixed
168 right after we got the ISOs operational.
</p
>
170 <p
>Another by-product of the test suite is that we can ask system
171 administrators with problems getting Debian Edu to work, to run the
172 test suite using
<tt
>/usr/sbin/debian-edu-test-install
</tt
> and see if
173 any errors are detected. This usually pinpoint the subsystem causing
174 the problem.

>The
<a href=
"http://www.skolelinux.org/
">Debian Edu and
191 Skolelinux
</a

192 globe. And a while back, an enterprising young man showed up on
193 <a href=
"irc://irc.debian.org/%
23debian-edu
">our IRC channel
194 #debian-edu
</a
> and started asking questions about how Debian Edu
195 worked. We answered as good as we could, and even convinced him to
196 help us with translations. And today I managed to get an interview
197 with him, to learn more about him.
</p

199 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
201 <p
>I
'm a
25 year old free software enthusiast, living in Romania,
202 which is also my country of origin. Back in
2009, at a New Year
's Eve
203 party, I had a very nice
<strike
>beer
</strike
> discussion with a
204 friend, when we realized we have no organised Debian community in our
205 country. A few days later, we put together the infrastructure for such
206 community and even gathered a nice Debian-ish crowd. Since then, I
207 began my quest as a free software hacker and activist and I am
208 constantly trying to cover as much ground as possible on that
211 <p
>A few years ago I founded a small web development company, which
212 provided me the flexible schedule I needed so much for my
213 activities. For the last
13 months, I have been the Technical Director
214 of
<a href=
"http://ceata.org/
">Fundația Ceata
</a
>, which is a free
215 software activist organisation endorsed by the FSF and the FSFE, and
216 the only one we have in our country.
</p
>
218 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
219 project?
</strong
></p
>
221 <p
>The idea of participating in the Debian Edu project was a surprise
222 even to me, since I never used it before I began getting involved in
223 it. This year I had a great opportunity to deliver a talk on
224 educational software, and I knew immediately where to look. It was a
225 love at first sight, since I was previously involved with some of the
226 technologies the project incorporates, and I rapidly found a lot of
227 ways to contribute.
</p
>
229 <p
>My first contributions consisted in translating the installer and
230 configuration dialogs, then I found some bugs to squash (I still
231 haven
't fixed them yet though), and I even got my eyes on some other
232 areas where I can prove myself helpful. Since the appetite for free
233 software in my country is pretty low, I
'll be happy to be the first
234 one around here advocating for the project
's adoption in educational
235 environments, and maybe even get my hands dirty in creating a flavour
236 for our own needs. I am not used to make very advanced plannings, so
237 from now on, time will tell what I
'll be doing next, but I think I
238 have a pretty consistent starting point.
</p

240 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
241 Edu?
</strong
></p
>
243 <p
>Not a long time ago, I was in the position of configuring and
244 maintaining a LDAP server on some Debian derivative, and I must say it
245 took me a while. A long time ago, I was maintaining a bigger
246 Samba-powered infrastructure, and I must say I spent quite a lot of
247 time on it. I have similar stories about many of the services included
248 with Skolelinux, and the main advantage I see about it is the
249 out-of-the box availability of them, making it quite competitive when
250 it comes to managing a school
's network, for example.
</p
>
252 <p
>Of course, there is more to say about Skolelinux than the
253 availability of the software included, its flexibility in various
254 scenarios is something I can
't wait to experiment
"into the wild
" (I
255 only played with virtual machines so far). And I am sure there is a
256 lot more I haven
't discovered yet about it, being so new within the

><strong
>What do you see as the disadvantages of Skolelinux / Debian
260 Edu?
</strong
></p
>
262 <p
>As usual, when it comes to Debian Blends, I see as the biggest
263 disadvantage the lack of a numerous team dedicated to the
264 project. Every day I see the same names in the changelogs, and I have
265 a constantly fear of the bus factor in this story. I
'd like to see
266 Debian Edu advertised more as an entry point into the Debian
267 ecosystem, especially amongst newcomers and students. IMHO there are a
268 lot low-hanging fruits in terms of bug squashing, and enough
269 opportunities to get the feeling of the Debian Project
's dynamics. Not
270 to mention it
's a very fun blend to work on!
</p
>
272 <p
>Derived from the previous statement, is the delay in catching up
273 with the main Debian release and documentation. This is common though
274 to all blends and derivatives, but it
's an issue we can all work
277 <p
><strong
>Which free software do you use daily?
</strong
></p
>
279 <p
>I can hardly imagine myself spending a day without Vim, since my
280 daily routine covers writing code and hacking configuration files. I
281 am a fan of the Awesome window manager (but I also like the
282 Enlightenment project a lot!),
283 <a href=
"http://www.claws-mail.org/
">Claws Mail
</a
> due to its ease of
284 use and very configurable behaviour. Recently I fell in love with
285 <a href=
"https://launchpad.net/redshift
">Redshift
</a
>, which helps me
286 get through the night without headaches. Of course, there is much more
287 stuff in this bag, but I
'll need a blog on my own for doing this!
</p
>
289 <p
><strong
>Which strategy do you believe is the right one to use to
290 get schools to use free software?
</strong
></p
>
292 <p
>Well, on this field, I cannot do much more than experiment right
293 now. So, being far from having a recipe for success, I can only assume
298 <li
>schools would like to get rid of proprietary software
</li
>
300 <li
>students will love the openness of the system, and will want to
301 experiment with it - maybe we need to harvest the native curiosity
302 of teenagers more?
</li
>
304 <li
>there is no
"right one
" when it comes to strategies, but it would
305 be useful to have some success stories published somewhere, so
306 other can get some inspiration from them (I know I
'd promote
309 <li
>more active promotion - talks, conferences, even small school
310 lectures can do magical things if they encounter at least one
311 person interested. Who knows who that person might be? ;-)
</li
>
315 <p
>I also see some problems in getting Skolelinux into schools; for
316 example, in our country we have a great deal of corruption issues, so
317 it might be hard(er) to fight against proprietary solutions. Also,
318 people who relied on commercial software for all their lives, would be
319 very hard to convert against their will.

'm a South-African free software geek who lives in Cape Town. My
338 days vary quite a bit since I
'm involved in too many things. As I
'm
339 getting older I
'm learning how to focus a bit more :)
</p

341 <p

'm also an Edubuntu contributor and I love when there are
342 opportunities for the Edubuntu and Debian Edu projects to benefit from
343 each other.

345 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
346 project?
</strong
></p
>
348 <p
>I
've been somewhat familiar with the project before, but I think my
349 first direct exposure to the project was when I met Petter
350 [Reinholdtsen] and Knut [Yrvin] at the Edubuntu summit in
2005 in
351 London. They provided great feedback that helped the bootstrapping of
352 Edubuntu. Back then Edubuntu (and even Ubuntu) was still very new and
353 it was great getting input from people who have been around longer. I
354 was also still very excitable and said yes to everything and to this
355 day I have a big todo list backlog that I
'm catching up with. I think
356 over the years the relationship between Edubuntu and Debian-Edu has
357 been gradually improving, although I think there
's a lot that we could
358 still improve on in terms of working together on packages. I
'm sure
359 we
'll get there one day.

361 <p
><strong

362 Edu?
</strong
></p

364 <p
>Debian itself already has so many advantages. I could go on about
365 it for pages, but in essence I love that it
's a very honest project
366 that puts its users first with no hidden agendas and also produces
367 very high quality work.
</p
>
369 <p
>I think the advantage of Debian Edu is that it makes many common
370 set-up tasks simpler so that administrators can get up and running
371 with a lot less effort and frustration. At the same time I think it
372 helps to standardise installations in schools so that it
's easier for
373 community members and commercial suppliers to support.

378 <p
>I had to re-type this one a few times because I
'm trying to
379 separate
"disadvantages
" from
"areas that need improvement
" (which is
380 what I originally rambled on about)
</p
>
382 <p
>The biggest disadvantage I can think of is lack of manpower. The
383 project could do so much more if there were more good contributors. I
384 think some of the problems are external too. Free software and free
385 content in education is a no-brainer but it takes some time to catch
386 on. When you
've been working with the same proprietary eco-system for
387 years and have gotten used to it, it can be hard to adjust to some
388 concepts in the free software world. It would be nice if there were
389 more Debian Edu consultants across the world. I
'd love to be one

3rd party solutions that they don

397 have access to after the service has ended and they could
've gotten so
398 much more value otherwise by being more self-sustainable and
399 autonomous.

">Debian Edu, also known as
466 Skolelinux
</a
>, is a Linux distribution based on Debian providing an
467 out-of-the box environment of a completely configured school
468 network. Immediately after installation a school server running all
469 services needed for a school network is set up just waiting for users
470 and machines being added via GOsa², a comfortable Web-UI. A netbooting
471 environment is prepared using PXE, so after initial installation of
472 the main server from CD, DVD or USB stick all other machines can be
473 installed via the network. The provided school server provides LDAP
474 database and Kerberos authentication service, centralized home
475 directories, DHCP server, web proxy and many other services. The

609 interview last November. But the developers and translators are still
610 pulling along to get the Wheezy based release out the door, and this
611 time I managed to get an interview from one of the French translators
612 in the project, Cédric Boutillier.

616 <p

34 year old. I live near Paris, France. I am an assistant

618 mathematics at the university and doing fundamental research in
619 probability in connexion with combinatorics and statistical physics.

622 and became Debian Developer a few months ago. I am working on Ruby
623 packaging, publicity and translation.

><strong
>How did you get in contact with the Skolelinux / Debian Edu
626 project?
</strong

628 <p
>I came to the Debian Edu project after a call for translation of

635 virtual machine when I was preparing localised version of some screen
636 shots for the manual. I was amazed to see it worked out of the box and
637 how comprehensive the list of software installed by default was.
</p
>
639 <p
>What amazed me was the complete network infrastructure directly
640 ready to use, which can and the nice administration interface provided
641 by
<a href=
"https://oss.gonicus.de/labs/gosa/
">GOsa²
</a
>. What pleased
642 me also was the fact that among the software installed by default,
643 there were many
"traditional
" educative software to learn languages,
644 to count, to program... but also software to develop creativity and
645 artistic skills with music (
<a href=

">Ardour

>,
646 <a href=
"http://audacity.sourceforge.net/

't much time to get more involved in this
653 beautiful project.
</p

655 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
656 Edu?
</strong
></p
>
658 <p
>For me, the main advantages of Skolelinux/Debian Edu are its
659 community of experts and its precise documentation, as well as the
660 fact that it provides a solution ready to use.
</p
>
662 <p
>I would add also the fact that it is based on the rock solid Debian
663 distribution, which ensures stability and provides a huge collection
664 of educational free software.
</p
>
666 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
667 Edu?
</strong
></p
>
669 <p
>Maybe the lack of manpower to do lobbying on the
670 project. Sometimes, people who need to take decisions concerning IT do
671 not have all the elements to evaluate properly free software
672 solutions. The fact that support by a company may be difficult to find
673 is probably a problem if the school does not have IT personnel.
</p
>
675 <p
>One can find support from a company by looking at
676 <a href=
"http://wiki.debian.org/DebianEdu/Help/ProfessionalHelp
">the
677 wiki dokumentation
</a
>, where some countries already have a number of
678 companies providing support for Debian Edu, like Germany or
679 Norway. This list is easy to find readily from the manual. However,
680 for other countries, like France, the list is empty. I guess that
681 consultants proposing support for Debian would be able to provide some
682 support for Debian Edu as well.

686 <p
>I am using the KDE Plasma Desktop. But the pieces of software I use

891 kan få til med en datamaskin til NOK

897 <p
>Jeg heter Nirosan Thiyagalingam. Jeg er
24 år og studerer
898 dataingeniør studiet ved Høgskolen i Sør Trøndelag. Interessen for
899 data har siden ung alder vært tilstede og jeg har i tillegg alltid
900 vært glad i å lære nye ting. Med teknologi som endres svært hurtig er
901 det alltid noe nytt å lære. Noe som igjen har gjort det svært
902 interessant å følge med på utviklingen. Jeg valgte dataingeniør
903 studiet grunnet ønske om å lære enda mer om programmering og utvikling
904 av store systemer.
</p
>
906 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
908 <p
>Skolelinux prosjektet hørte jeg først om i media. Men det var først
909 når jeg skulle velge bacheloroppgave at jeg fattet mer interesse for
910 prosjektet. Et enkelt søk på nettet førte meg til skolelinux sine
911 hjemmesider. Informasjonen jeg fant der gjorde meg enda nysgjerrig og
912 jeg valgte derfor en oppgave som gikk ut på å få en
913 <a href=
"http://www.raspberrypi.org
">Raspberry PI
</a
>. Altså en
914 ultra-billig datamaskin til å kjøre Debian Edu på lik linje med
915 vanlige datamaskiner. I løpet av prosjektet ble det gjort mye
916 forskning på nettet. Det var mye jeg måtte forstå rundt hvordan
917 operativsystemet Linux fungerte før jeg kunne angripe
918 problemet. Prøvde først å finne ut hvordan man kunne transformere en
919 vanlig installasjon av Skolelinux til Raspberry PI, men dette var
920 altfor vanskelig å jeg endte opp med mer spørsmål enn svar. Det ble
921 videre opprettet kontakt med Skolelinux utviklere på IRC der jeg fikk
922 diskutert hvilken retning jeg burde gå for å få til en fullverdig
923 løsning. Det ble bestemt at jeg skulle gå for å først installere
924 <a href=
"http://www.raspbian.org/
">Raspian
</a
>. Dette er et
925 operativsystem basert på Debian spesiallaget for Raspberry Pi sin
926 maskinvare. Nå som Debian var installert på datamaskinen gjenstod det
927 å installere de nødvendige Skolelinux pakkene for å få til et
928 fullverdig system. Disse pakkene ble installert manuelt i første
929 omgang, men ble senere installert automatisk via et script som Petter
930 Reinholdtsen laget. Dette scriptet er så enkel å bruke at man er i
931 gang med installasjonen i løpet av bare
5 minutter. Ikke nok med det,
932 alt skjer helt automatisk. Alt i alt er jeg veldig fornøyd med
933 resultatet av installasjonsprosessen. Raspberry Pi er en veldig svak
934 maskin og det merkes godt når man har installert Skolelinux på
935 den. Video og
3D-rendering fungerer utrolig dårlig, men nettsurfing og
936 kontorprogrammer fungerer godt. Det kan derfor konkluderes med at
937 datamaskinen er egnet for enkle oppgaver.
939 <p
>Jeg syns det er viktig påpeke at dette kun er startfasen av en slik
940 løsning. På markedet finnes det nå maskiner som har bedre hardware enn
941 Raspberry Pi. Det er store muligheter for at man kan klare å
942 installere Skolelinux på disse også, og da forsvinner nok mest
943 sannsynlig ytelsesproblemene med Video og
3D rendering også.
</p
>
945 <p
>Det ble også prøvd med en løsning som gjorde at Raspberry Pi
946 fungerte som en tynnklient. Denne løsningen hadde langt bedre ytelse
947 med tanke på hastighet og brukeropplevelse. Men også her var video og
948 3D rendering dårlig. Det ble brukt en liten Linux distribusjon kalt
949 <a href=

</a

952 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
954 <p
>Fordelen med Skolelinux er mange. At det er gratis er en stor
955 fordel, men at det er så mange som er med på å utvikle det og
956 vedlikeholde det er en enda større fordel. Allerede før jeg startet
957 med prosjektet så jeg mange fordeler, og når jeg nærmet meg sluttfasen
958 så jeg langt flere. At prosjektet skulle inneha en så høy kvalitet
959 hadde jeg aldri trodd. En vanlig Skolelinux installasjon har de
960 nødvendige programmene og funksjonen som både små og store skoler i
961 tillegg til organisasjoner kan klare seg med. At prosjektet tilbyr en
962 så komplett løsning er en kjempefordel. Installasjonen er knirkefri
963 og det er svært enkelt å installere og komme i gang.
</p
>
965 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
967 <p
>Ulempene jeg ser med prosjektet er ryddigheten av websidene. Selv
968 om websidene er enkle og konsise er det allikevel ikke appellerende i
969 like stor grad som for eksempel
970 <a href=
"http://www.ubuntu.com
">Ubuntu
</a
> sine sider. Deres side
971 tilbyr, i tillegg til godt design og presentasjon, en nettbasert
972 emulator av deres operativsystem. Dette er en stor fordel slik jeg ser
973 det. Bortsett fra dette ser jeg absolutt ingen ulemper med
974 Skolelinux-prosjektet.
</p

976 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
978 <p
>Til daglig er jeg en flittig bruker av det åpne media
979 sentersystemet
<a href=
"http://xbmc.org/
">XBMC
</a
>. Det enorme
980 samfunnet rundt dette prosjektet har gjort dette til et program som
981 dekker alles behov. Man kan tilpasse det akkurat slik man vil både med
982 tanke på utseende og funksjoner ved installere plug-ins eller
985 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
986 skoler til å ta i bruk fri programvare?
</strong
></p
>
988 <p
>Strategien som burde brukes sett fra mine øyne er
989 markedsføring. Jeg er sikker på at om flere skoler fikk et lite innsyn
990 i hvor bra Skolelinux er så ville de ikke nølt med å gå over fra noe
991 annet som koster de store summer. At skolelinux til de grader tilbyr
992 en så komplett løsning bure komme frem. Enten via reklamekampanjer
993 eller ved å sende ut folk til skoler for så å la skolenettverk
994 ansvarlige få teste ut hvordan Skolelinux fungerer i praksis. Om det
995 i tillegg ble utviklet gode websider og en emulator for å la brukere
996 prøve operativsystemet ville nok dette ha styrket inntrykket
997 betraktelig.

1021 the Debian Edu installer.

</p

1031 <li

1036 /etc/debian-edu/config, and run tasksel to install packages
1037 according to the profile specified in the config above,
1038 overriding some of the Debian automation machinery.

1045 <p

1091 <p
>Debian Edu, also known as Skolelinux, is a Linux distribution based
1092 on Debian providing an out-of-the box environment of a completely
1093 configured school network. Immediatly after installation a school
1094 server running all services needed for a school network is set up just
1095 waiting for users and machines being added via GOsa², a comfortable
1096 Web-UI. A netbooting environment is prepared using PXE, so after
1097 initial installation of the main server from CD, DVD or USB stick all
1098 other machines can be installed via the network.

">Debian Edu, also known as
1251 Skolelinux
</a
>, is a Linux distribution based on Debian providing an
1252 out-of-the box environment of a completely configured school
1253 network. Immediatly after installation a school server running all
1254 services needed for a school network is set up just waiting for users
1255 and machines being added via GOsa², a comfortable Web-UI. A netbooting
1256 environment is prepared using PXE, so after initial installation of
1257 the main server from CD, DVD or USB stick all other machines can be
1258 installed via the network.

6. He installed the standalone profile and
1384 the video show a walk-through of of the menu content, demonstration of
1385 a few programs and his view of our distribution.
</p
>
1387 <p
>There is also some really nice quotes (transcribed by me, might
1388 have heard wrong). While looking thought the Graphics menu:
</p
>
1391 "Basically everything you ever need in a school environment.
"
1394 <p
>And as a general evaluation of the entire distribution:
</p
>
1397 "So, yeah, a bit bloated. It kept all the Debian stuff in there, just
1398 to keep it nice and GNU. So, I do not want to go on about it, but
1399 lets give it
7 out of
10. I am not going to use it. That is because
1400 I am not deploying a school network. There may be some mythical
1401 feature to help you deploy Skolelinux on a school network.
"
1404 <p
>To bad he did not test the server profile, and discovered the PXE
1405 installation option. It make it possible to install only the main
1406 server from CD, and the rest of the machines via the net, and might be
1407 considered the mythical feature he talk about. :)
</p
>
1409 <p
>While looking through the menus, there is also this funny comment
1410 about the part of the K menu generated from the Debian menu subsystem:
1413 "[The K menu] have a special Debian section for software that no-one
1414 is going to look at, because it contain lots of junky stuff that you
1415 actually don
't need in the education distribution, but have just been
1416 included because it isn
't stripped out for some reason.
"
1419 <p
>I guess it is yet another argument for merging the Debian menu and
1420 Gnome/KDE desktop menu entries into
1421 <a href=
"http://wiki.debian.org/Proposals/DebianMenuUsingDesktopEntries
">one
1422 consistent menu system
</a
> instead of two incomplete and partly
1423 inconsistent menu systems.

</a

1537 Denne gang er det Helge Tore Høyland, en mangeårig bidragsyter på
1538 epostlistene og ellers i prosjektet.
</p

1540 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
1542 <p
>Eg er IT-konsulent/teknikker hjå eit firma i Steinkjer med navn
1543 <a href=
"http://unoit.no/
">Uno IT
</a
>. Uno IT er eit lite firma som
1544 drifter nettverk og maskiner for små og mellomstore firma
1545 Steinkjer-området. Per dags dato er me
2 ansatte. Min faglege bakgrunn
1546 er Fagbrev som it-teknikker, samt nokre fag innen nettverk- og
1547 server-drift frå HiST og NTNU. Dagleg arbeid består i oppsett av nye
1548 maskiner og hjelp til sluttbrukere, samt oppsett og vedlikehold av eit
1549 vidt spekter av fagsystemer ute hjå kunder. Erfaring med Skolelinux
1550 har eg hatt i forbindelse med drifting av
1551 <a href=
"http://www.bjorkly.no/
">Bjørkly skule
</a
>, ein privat
1552 grunnskule i Namsos-området. I dag har skulen
65 elever,
15 lærere,
1
1553 hovedserver og ca
60 klienter som kjører halvtjukt. Eg har bygd og
1554 driftet systemet sidan summaren
2006.
</p
>
1556 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
1558 <p
>Eg kom i kontakt med Skolelinux-prosjektet via ein artikkel i eit
1559 fagblad, som eg ikkje lenger hugsar namnet på. I og med at eg allereie
1560 hadde pusla med nettverk for ein annan skule, fatta eg straks
1561 interesse for prosjektet.
</p
>
1563 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
1565 <p
>Fordelane med Skolelinux er sentralisert administrasjon og svært
1566 mange gode verktøy «ut av boksen». Veldig kjekt å kunne drifte
60
1567 klientar med berre å «bry» seg med ein server. Levetid for systemets
1568 hardware er og ein veldig fin effekt. I tillegg kjem fordelar som økt
1569 sikkerhet og mindre lisenskostnader. Etter min erfaring er det og
1570 mykje mindre driftskostnader med eit slikt system enn konkurrerande
1571 system, pga enkelhet med sentralisert administrasjon. På grunn av at
1572 Skolelinux er basert på Debian er det òg svært stabilt.
</p
>
1574 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
1576 <p
>Ulemper er mangel på vilje til å følge standarer ute i markedet,
1577 som fører til mangel på støtte til nokre mykje brukte ting. Flash og
1578 Java er typiske eksempel. Sidan Debian satsar på stabilitet framfor å

1580 at program vert «for gamle». Det er spesielt nettlesaren som er
1581 utsett. Mangel på vilje til å utvikle pedagogisk programvare, i Noreg,
1582 for «alle» platformer fører òg til noko hovudbry.

>Strategisk må ein fokusere på at sluttbruker eigentleg ikkje er så
1594 fokusert på at det er fri programvare men at det skal «berre fungere».
1595 Gjer det enkelt å bruker og ikkje minst å administrere. For Skolelinux
1596 sin del må ein få eit betre fokus på overganger. Utbytting av servere
1597 må gå meir automatisk, import og eksport av brukerbase og maskinbase
1598 med meir må kunne gå enkelt og oppgradering til neste versjon må bli
1599 mykje meir automatisk og gjennomtesta. Ein må unngå at ein må sette
1600 opp frå start når ein byter ut ein server eller oppgraderer til neste
1601 versjon. For å få Skolelinux til å bli eit betre alternativ for skular
1602 må ein ha fokus på nettlesaren. Denne må bli «up to date» og støtte
1603 dei protokollar og tillegg som vert brukt av forlag med meir. Etter
1604 kvart som meir og meir blir flytta ut i «skya» vert dette viktigare og
1605 viktigare. Ein kunne ynskje og jobbe for at forlag med fleire tar i
1606 bruk opne standarer, men inntil det skjer, må systemet kunne brukast
1607 mot desse fagsystema.

1609 <p
>For meg har prosjektet med Skolelinux vore ein svært artig og
1610 lærerik prosess. Miljøet rundt er ikkje enormt stort, dog stort nok,
1611 men det er svært hjelpevillig og engasjert.

1711 welcome to Angela Fuß. :)
</p
>
1713 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
1715 <p
>I am a
39-year-old woman living in the very north of Germany near
1716 Denmark. I live in a patchwork family with
"my man
" Mike Gabriel, my
1717 two daughters, Mikes daughter and Mikes and my rather newborn son.
1719 <p
>At the moment - because of our little baby - I am spending most of
1720 the day by being a caring and organising mom for all the kids.
1721 Besides that I am really involved into and occupied with several inner
1722 growth processes: New born souls always bring the whole familiar
1723 system into movement and that needs time and focus ;-). We are also
1724 in the middle of buying a house and moving to it.
</p
>
1726 <p
>In
2013 I will work again in my job in a German foundation for
1727 nature conservation. I am doing public relation work there. Besides
1728 that - and that is the connection to Skolelinux / Debian Edu - I am
1729 working in our own school project
"IT-Zukunft Schule
" in North
1730 Germany. I am responsible for the quality assurance, the customer
1731 relationship management and the communication processes in the
1734 <p
>Since
2001 I constantly have been training myself in communication
1735 and leadership. Besides that I am a forester, a landscaping gardener
1736 and a yoga teacher.
</p
>
1738 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
1739 project?
</strong
></p
>
1741 <p
>I fell in love with Mike ;-).
</p
>
1743 <p
>Very soon after getting to know him I was completely enrolled into
1744 Free Software. At this time Mike did IT-services for one newly
1745 founded school in Kiel. Other schools in Kiel needed concepts for
1746 their IT environment. Often when Mike came home from working at the
1747 newly founded school I found myself listening to his complaints about
1748 several points where the communication with the schools head or the
1749 teachers did not work. So we were clear that he would not work for
1750 one more school if we did not set up a structure for communication
1751 between him, the schools head, the teachers, the students and the
1754 <p
>Together with our friend and hardware supplier Andreas Buchholz we
1755 started to get an overview of free software solutions suitable for
1756 schools. One day before Christmas
2010 Mike and I had a date with Kurt
1757 Gramlich in Gütersloh. As Kurt and I are really interested in building
1758 networks of people and in being in communication we dived into
1759 Skolelinux and brought it to the first grammar schools in Northern

1766 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
1767 Edu?
</strong
></p
>
1769 <p
>First I have to say: I cannot answer this question technically. My
1770 answer comes rather from a social point of view.
</p
>
1772 <p
>The biggest advantage of Skolelinux / Debian Edu I see is the large
1773 and strong international community of Debian Developers in the
1774 background which is very alive and connected over mailinglists, blogs
1775 and meetings. My constant feeling for the Debian Community is: If
1776 something does not work they will somehow fix it. All is well
1777 ;-). This is of course a user experience. What I also get as a big
1778 advantage of Skolelinux / Debian Edu is that everybody who uses it and
1779 works with it can also contribute to it - that includes students,
1780 teachers, parents...
</p
>
1782 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
1783 Edu?
</strong
></p
>
1785 <p
>I will answer this question relating to the internal structure of
1786 Skolelinux / Debian Edu.
</p
>
1788 <p
>What I see as a major disadvantage is that there is a gap between
1789 the group of developers for Debian Edu and the people who make the
1790 marketing, that means the people that bring Skolelinux to the
1791 schools. There is a lack of communication between these two groups and
1792 I think that does not really work for Skolelinux / Debian Edu.
</p
>
1794 <p
>Further I appreciate that Skolelinux / Debian Edu is known as a
1795 do-ocracy. Nevertheless I keep asking myself if at some points a
1796 democracy or some kind of hierarchical project structure would be good
1797 and helpful. I am also missing some kind of contact between the
1798 Skolelinux / Debian Edu communities in Europe or on an international
1799 level. I think it would be good if there was more sharing between the
1800 different countries using Skolelinux / Debian Edu.
</p

1802 <p
><strong
>Which free software do you use daily?
</strong
></p
>
1804 <p
>On my laptop I am still using an Ubuntu
10.04 with a Gnome Desktop
1805 on. As applications I use Openoffice.org, Gedit, Firefox, Pidgin,
1806 LaTeX and GnuCash. For mails I am using Horde. And I am really fond of
1807 my N900 running with Maemo.
</p
>
1809 <p
><strong
>Which strategy do you believe is the right one to use to
1810 get schools to use free software?
</strong
></p
>
1812 <p
>I am really convinced that in our school project
"IT-Zukunft
1813 Schule
" we have developed (and keep developing) a great way to get
1814 schools to use Free Software. We have written a detailed concept for
1815 that so I cannot explain the whole thing here. But in a nutshell the
1816 strategy has three crucial pillars:
</p
>
1820 <li
>We really take time to get what sort of stories, questions and
1821 concerns the schools head and the teachers have about using different
1822 kinds of IT and we take time to enrol them into Free Software.
</li
>
1824 <li
>Our solution for schools is never just technical. In the centre
1825 are always the people who are going to use the software. From the very
1826 beginning of the planning for a school, we tell the schools head that
1827 they are paying us not only for a technical solution for their school,
1828 they also pay us for leading all the communication processes
1829 needed. If they do not want that, we are not working with them because
1830 we cannot give a guarantee for the quality of our work then.
</li
>
1832 <li
>Another focus lies in the training of teachers and students in
1833 co-administrating the IT-System at their school. They start getting in
1834 contact with the Skolelinux / Debian Edu community and they get the
1835 offer to become more and more independent from us.

1858 <p
>I sommer (
2012-
07-
23) hadde Fremover et oppslag om at Narvik
1859 kommune hadde spart mellom
10 og
20 millioner kroner de siste årene på
1860 å bruke Skolelinux på sine skoler. Harstad har også tatt i bruk
1861 Skolelinux på alle sine skoler. Som tidligere Ballangsværing gledet
1862 det meg stort å se at skoleløsningen vi har utviklet siden
2001 tas i
1863 bruk i området der jeg vokste opp, og dermed bidrar til en bedre og
1864 billigere skolehverdag.
</p
>
1866 <p
>Skolelinux er en komplett IT-løsning for elevnettverket på en
1867 skole, med både nettverkstjenester og løsning for elevmaskiner med
1868 pedagogisk programvare, som tillater en å øke levetiden på en
1869 datamaskin i skolen med mange år. En undersøkelse publisert i mars
1870 2012 viste at de
56 norske skolene som har offentliggjort at de bruker
1871 Skolelinux eller annen Linuxutgave hadde
36% større PC-tetthet enn
1872 landsgjennomsnittet, når en ser på tall rapportert til Grunnskolens
1873 Informasjonssystem. I følge Paul Reidar Løsnesløkken, IKT-konsulent i
1874 Nord-Odal, fungerer datamaskiner godt til de er
8 til
10 år gamle.
</p
>
1876 <p
>I høst (
2012-
09-
29) fortalte Fremover hvordan Ballangen kommune har
1877 opparbeidet seg
20 millioner i underskudd og nok havner på Robek-lista
1878 fra nyttår. Kanskje Ballangen også burde ta i bruk Skolelinux for å
1879 spare penger? Hvis kommunen mangler kompetanse lokalt på Linux finnes
1880 det kommersielle selskaper som tilbyr driftstjenester rundt
1881 Skolelinux, og jeg bør vel avsløre at jeg selv er involvert i et av
1882 dem, Skolelinux Drift AS. Kommunen kan dermed få hjelp hvis de ikke
1883 ønsker å bygge opp egen kompetanse.

>After a long break in my row of interviews with people in the
2051 <a href=
"http://www.skolelinux.org/
">Debian Edu and Skolelinux
</a
>
2052 community, I finally found time to wrap up another. This time it is
2053 Giorgio Pioda, which showed up on the mailing list at the start of
2054 this year, asking questions and inspiring us to improve the first time
2055 administrators experience with Skolelinux. :) The interview was
2056 conduced in May, but I only found time to publish it now.

2058 <p
><strong
>Who are you, and how do you spend your days?
</strong

2060 <p
>I have a PhD in chemistry but since several years I work as teacher
2061 in secondary (
15-
18 year old students) and tertiary (a kind of
"light
"
2062 university) schools. Five years ago I started to manage a Learning
2063 Management Service server and slowly I got more and more involved with
2064 IT.
3 years ago the graduating schools moved completely to Linux and I
2065 got the head of the IT for this. The experience collected in chemistry
2066 labs computers (for example NMR analysis of protein folding) and in
2067 the IT-courses during university where sufficient to start. Self
2068 training is anyway very important
</p
>
2070 <p
>I live in the Italian speaking part of Switzerland, and the
2071 <a href=
"http://www.spse.ch/
">SPSE school
</a
> (secondary) is a very
2072 special sport school for young people who try to became sport pro (for
2073 all sports, we have dozens of disciplines represented) and we are
2074 recognised by the Olympic Swiss Organisation.
2076 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
2077 project?
</strong
></p
>
2079 <p
>Looking for Linux / Primary Domain Controller (PDC) I found it
2080 already several years ago. But since the system was still not
2081 Kerberized and since our schools relies strongly on laptops I didn
't
2082 use it. I plan to introduce it in the next future, probably for the
2083 next school year, since the squeeze release solved this security
2086 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
2087 Edu?
</strong
></p
>
2089 <p
>Many. First of all there is a strong and living community that is
2090 very generous for help and hints. Chat help is crucial, together with
2091 the mailing list. Second. With Skolelinux you get an already well
2092 engineered platform and you don
't have to start to build up your PDC
2093 and your clients from GNU/scratch; I
've already done this once and I
2094 can tell it, it is hard. Third, since Skolelinux is a standard
2095 platform, it is way easier to educate other IT people and even if the
2096 head IT is sick another one could pick up the task without too much
2099 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
2100 Edu?
</strong
></p
>
2102 <p
>The only real problem I see is that it is a little too less
2103 flexible at client level. Debian stable is rocky and desirable, but
2104 there are many reasons that force for another choice. For example the
2105 need of new drivers for new PC, or the need for a specific OS for some
2106 devices that have specific software packages for another specific
2107 distribution (I have such a case for whiteboards that have only
2108 Ubuntu packages). Thus, I prepared compatibility packages educlient
2109 and eduroaming, hoping not to use them ;-)
</p
>
2111 <p
><strong
>Which free software do you use daily?
</strong
></p
>
2113 <p
>I have a Debian Stable PDC at school (Kerberos, NIS, NFS) with
2114 mixed Debian and Ubuntu clients. If you think that this triad
2115 combination is exotic... well I discovered right yesterday that
2116 <a href=
"http://moo.nac.uci.edu/~hjm/Perceus-Report.html
">Perceus
</a
>
2117 has the same...
</p
>
2119 <p
>For myself I run Debian wheezy/sid, but this combination is good
2120 only I you have enough competence to fix stuff for yourself, if
2121 something breaks. Daily I use texmacs, gnumeric, a little bit of R
2122 statistics, kmplot, and less frequently OpenOffice.org.
</p
>
2124 <p
><strong
>Which strategy do you believe is the right one to use to
2125 get schools to use free software?
</strong
></p
>
2127 <P
>I think that the only real argument that school managers
"hear
" is
2128 cost reduction. They don
't give too much weight on quality, stability,
2129 just because they are normally not open to change.
</p
>
2131 <p
>Students adapts very quickly to GNU/Linux (and for them being able
2132 to switch between different OS is a plus value); teachers and managers
2133 don
't.
</p
>
2135 <p
>We decided to move to Linux because students at our school have own
2136 laptop and we have the responsibility to keep the laptop ready to use;
2137 we were really unsatisfied with Microsoft since every Monday we had
20
2138 machine to fix for viral infections... With Linux this has been
2139 reduced to zero, since people installs almost only from official
2140 repositories. I think that our special needs brought us to Linux.
2141 Those who don
't have such needs will hardly move to Linux.

</p

2158 <p
>Artikkelen med tittelen
"Narvik kommune bruker gratisprogram i
2159 skolen - Har spart millioner
", forteller om hvordan bruken av
2160 Skolelinux er en stor suksess i Narvik siden det ble tatt i bruk i
2161 2004. Her er noen fine sitater:
</p
>
2164 "- Skolelinux har spart kommunen for store pengesummer, millionbeløp,
2165 som de heller kan bruke på andre ting, sier IKT-konsulent Viggo
2169 <p
>Avisen forteller at de har fått tilgang til beregninger som viser
2170 at Narvik kommune har spart noe mellom
10 og
20 millioner kroner de
2171 siste
8 årene på å bruke Skolelinux, og fortsetter:
</p
>
2175 "Regnestykket tar høyde for sparte kostnader til lisenser som medfølger
2176 de alternative operativsystemene, lavere driftskostnader og lengre
2177 levetid på datautstyret. Totalt har Narvikskolen en maskinpark på
2178 1600 maskiner fordelt på de
11 skolene fra Skjomen i sør til Bjerkvik
2183 <p
>Viggo Fedreheim sier dette om hvor noe av gevinsten kommer fra:
</p
>
2186 "- Vi kan gjenbruke gamle maskiner i skolen som er for dårlig andre
2187 steder i kommunen der de ikke bruker Skolelinux. Levetiden på en
2188 datamaskin blir
3-
5 år lenger med Skolelinux. Vi kaller det for
2189 grønn IT, miljøvennlig IT.
"
2192 <p
>Her er det mulighet for flere kommuner å få et godt IT-system på
2193 skolene, hvis de er villige til å forsøke. De som ikke har kompetanse
2194 innomhus kan kjøpe det fra en av de kommersielle leverandørene av

'm a
44 year old country guy that have been working
12 years at
2270 the same school as
50% IT-manager and
50% Teacher. My educational
2271 background is fil.kand in history and religious beliefs, an exam as a
2272 "folkhighschool

2273 Norwegian I believe it
's called
"Vuxenupplaring
". I also have a master
2274 in
"Technology and social change
". So I
'm not really a tech guy, I
2275 just like to study how humans and technology interact and that is my
2276 perspective when working with IT.
</p
>
2278 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
2279 project?
</strong
></p
>
2281 I have followed the Skolelinux project for quite some time by
2282 now. Earlier I tested out the K12-LTSP project, which we used for some
2283 time, but I really like the idea of having a distribution aimed to be
2284 a complete solution for schools with necessary tools integrated. When
2285 K12-LTSP abandoned that idea some years ago, I started to look more
2286 seriously into Skolelinux instead.
2288 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
2289 Edu?
</strong
></p
>
2291 The big point of Skolelinux to me is that it is a complete
2292 distribution, ready to install. It has LDAP-support, MS Windows
2293 integration tools and so forth already configured, saving an
2294 administrator a lot of time and headache. We were using another Linux
2295 based thin-client system called Thinlinc, that has served us very
2296 well. But that Skolelinux is based on VNC and LTSP, to me, is better
2297 when it comes to the kind of multimedia used in schools. That is
2298 showing videos from Youtube or educational TV. It is also easier to
2299 mix thin clients with workstations, since the user settings will be the
2300 same. In our VNC-based solution you had to
"beat around the bush
" by
2301 setting up a second, hidden, home-directory for user settings for the
2302 workstations, because they will be different from the ones used on the
2303 thin clients. Skolelinux support for diskless workstations are very
2304 convenient since a school today often need to use a class room
2305 projector showing videos in full screen. That is easily done with a
2306 small integrated media computer running as a diskless workstation. You
2307 have only two installs to update and configure. One for the thin
2308 clients and one for the workstations. Also saving a lot of time. Our
2309 old system was also based on Redhat and CentOS. They are both very
2310 nice distributions, but they are sometimes painfully slow when it
2311 comes to updating multimedia support and multimedia programs (even
2312 such as Gimp), leaving us with a bit
"oldish
" applications. Debian is
2315 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
2316 Edu?
</strong
></p
>
2318 <p
>Debian is a bit too quick when it comes to updating. As an example
2319 we use old HP terminals as thinclients, and two times already this
2320 year (
2012) the updates you get from the repositories has stopped
2321 sound from working with them. It
's a kernel/ALSA issue. So you have
2322 to be more careful properly testing the updates before you run them in
2323 a production environment. This has never happened with CentOS.
</p
>
2325 <p
>I also would like to be able to set my own domain-settings at
2326 install time. In Skolelinux they are kind of hard coded into the
2327 distribution, when it comes to LDAP and at least samba integration.
2328 That is more a cosmetic/translation issue, and not a real problem.
2329 Running MS Windows applications within the Skolelinux environment needs
2330 to be better supported. That is, running them seamlessly via RDP, and
2331 support for single-sign on. That will make the transition to free
2332 software easier, because you can keep the applications you really
2333 need. No support will make it impossible if you work in a school where
2334 some applications can
't be open source. As for us we really need to
2335 run Adobe InDesign in our journalist classes. We run a journalist
2336 education, and is one of the very few non university ones that is ok:d
2337 by Svenska journalistförbundet (Swedish journalist association). Our
2338 education gives the pupils the right of membership there, once they
2339 are done. This is important if you want to get a job.
</p
>
2341 <p
>Adobe InDesign is the program most commonly used in newspapers and
2342 magazines. We used Quark Express before, but they seem to loose there
2343 market to Adobe. The only
"equivalent
" to InDesign in the opensource
2344 world is Scribus, and its not advanced enough. At least not according
2345 to the teacher. I think it would be possible to use it, because they
2346 are not supposed to learn a program, they are supposed to learn how to
2347 edit and compile a newspaper. But politically at our school we are not
2348 there yet. And Scribus lacks a lot of things you find i InDesign.
</p
>
2350 <p
>We used even a windows program for sound editing when it comes to
2351 the radio-journalist part. The year to come we are going to try
2352 Audacity. That software has the same kind of limitations compared to
2353 Adobe Audition, but that teacher is a bit more open minded. We have
2354 tried Ardour also, but that instead is more like a music studio
2355 program, not intended for the kind of editing taking place in a radio
2356 studio. Its way to complex and the GUI is to scattered when you only
2357 want to cut, make pass-overs, add extra channels and normalise. Those
2358 things you can do in Audacity, but its not as easy as in Audition. You
2359 have to do more things manually with envelopes, and that is a bit old
2360 fashion and timewasting. Its also harder to cut and move sound from
2361 one channel to another, which is a thing that you do frequently
2362 because you often find yourself needing to rearrange parts of the
2363 sound file.
</p
>
2365 <p
>So, I am not sure we will succeed in replacing even Audition, but we
2366 will try. The problem is the students have certain expectations when
2367 they start an education towards a profession. So the programs has to
2368 look and feel professional. Good thing with radio, there are many
2369 programs out there, that radio studios use, so its not as standardised
2370 as Newspaper editing. That means, it does not really matter what
2371 program they learn, because once they start working they still have to
2372 learn the program the studio uses, so instead focus has to be to learn
2373 the editing part without to much focus on a specific software.

2377 <p
>Myself I
'm running Linux Mint, or Ubuntu these days. I use almost
2378 only open source software, and preferably Linux based. When it comes
2379 to most used applications its OpenOffice, and Firefox (of course ;)
2382 <p
><strong
>Which strategy do you believe is the right one to use to
2383 get schools to use free software?
</strong
></p

2385 <p
>To get schools to use free software there has to be good open
2386 source software that are windows based, to ease the transition. But
2387 it
's also very important that the multimedia support is working
2388 flawlessly. The problems with Youtube, Twitter, Facebook and whatever
2389 will create problems when it comes to both teachers and
2390 students. Economy are also important for schools, so using thin
2391 clients, as long as they have good multimedia support, is a very good
2392 idea. It
's also important that the open source software works even for
2393 the administration. It
's hard to convince the teachers to stick with
2394 open source, if the principal has to run Windows. It also creates a
2395 problem if some classes has to use Windows for there tasks, since that
2396 will create a difference in
"status
" between classes, so a good
2397 support for running windows applications via the thin client (Linux)
2398 desktop is essential. At least at our school, where we have mixed
2399 level of educations, from high-school to journalist-school.

>In the Debian Edu / Skolelinux project, we have realised that one
2419 of the major blockers for the project success is the purchasing skills

2421 Debian Edu / Skolelinux say they need and to a lower cost than the

>Fruen og jeg dro på en lengre seiltur i
2000, der jeg måtte ha
"noe
2645 å gjøre
" under hjemturen over Atlanteren. Jeg kjøpte et par bøker om
2646 Linux i en bokhandel i New York og ble veldig fascinert. Etter
2647 hjemkomsten begynte jeg å jobbe på Ulsrud VGS, som naturfagslærer, men
2648 som IT-interessert ble jeg fort en del av den nye IT-satsningen som
2649 skulle løfte Ulsrud og gi skolen en bedre rykte. Vi hadde ganske
2650 mange maskiner, som gikk på Win98 og to servere som ble oppgradert til
2651 Win2000. Systemene var ustabil og dårlige. På leting etter noe
2652 bedre, uten å knekke ryggen økonomisk, kom jeg over
"Linux i Skolen
"
2653 og Skolelinux. Jeg tok kontakt med miljøet og en gjeng møtte opp på
2654 skolen, der vi gjorde en liten testinstallasjon. Etter et par år var
2655 ryggraden på skolen Linux (Skolelinux) og vi hadde flere hundre
2656 maskiner, både tynne klienter (gamle og nye), bærbare (Debian) og noen
2657 stasjonære (Win2000). På et tidspunkt var Ulsrud den råeste IT-skolen
2658 og det irriterte skolesjefen i Oslo, da de satset hardt på

2663 <p
>Det som gjorde at vi fikk inn Skolelinux var ene og alene
2664 økonomiske. Det faktum at vi slapp å kjøpe masse nye lisenser og at
2665 vi kunne bruke gammel hardware. Alt i alt gjorde dette at vi sparte
2666 mye, men i stede for å bruke mindre på IT brukte vi det vi sparte på å
2667 skaffe mer hardware og på den måten gi det beste tilbudet i landet til
2668 våre elever. For oss som driftet var det himmel å ha et system som
2669 gikk å administrere sentralt og effektivt. Det var heller ikke så
2670 dumt at vi kunne
"låse
" maskinene mer effektivt enn vi kunne med
2671 Microsoft Windows, slik at vi slapp mye feil og problemer som ble
2672 forårsaket av
"kreative
" elever.

2686 HandBrake mye, og jeg har installert OpenWRT på flere av
2687 basestasjonene både hjemme og på jobben. I tillegg til det har jeg i
2688 flere år finansiert et prosjekt som heter

2697 man må oppfylle minimumskravene (ikke være best, men bra nok) og selge
2698 seg inn på hvor mye man sparer. Det betyr selvsagt at man sparer på
2699 lisenser, men også på driftsinnsats. Men nå når jeg ikke er en aktiv
2700 del av miljøet lenger hører jeg nesten ingen ting om fri programvare.
2701 Jeg stiller meg da spørsmålet om det har blitt stille rundt miljøet,
2702 eller om jeg kun så det tydeligere før når jeg var aktiv? Uansett er
2703 det for stille rundt Skolelinux-prosjektet nå.

</strong

2763 <p
>I think there is not a single strategy because there are very
2764 different scenarios: schools with mixed proprietary and free
2765 environments, schools using only workstations, other schools using
2766 laptops, netbooks, tablets, interactive white-boards, etc.
</p

2768 <p
>Also the range of ages of the students is very broad and you can
2769 not use the same solutions for primary schools and secondary or even
2770 universities. So different strategies are needed.
</p
>
2772 <p
>But, looking at these differences, and looking back to the things
2773 we
've done and implemented, and the places were we have spent most of
2774 our forces, I think we should focus as much as possible in free
2775 multi-platform environments, using only standards tools, and moving
2776 more and more to Internet or network solutions that could be deployed
2777 using wireless. I think we
'll see more and more personal devices in
2778 the schools, devices the students and teachers will take home with
2779 them, so the solutions must be able to be taken at home and continue
2780 working there.

>During my work on
2790 <a href=
"http://www.debian.org/News/
2012/
20120311.nb.html
">Debian Edu
2791 based on Squeeze
</a
>, I came across some issues that should be
2792 addressed in the Wheezy release. I finally found time to wrap up my
2793 notes and provide quick summary of what I found, with a bit
2794 explanation.
</p
>
2798 <li
>We need to rewrite our package installation framework, as tasksel
2799 changed from using tasksel tasks to using meta packages (aka packages
2800 with dependencies like our education-* packages), and our installation
2801 system depend on tasksel tasks in
2802 /usr/share/tasksel/debian-edu-tasks.desc for package
2803 installation.
</li
>
2805 <li
>Enable Kerberos login for more services. Now with the Kerberos
2806 foundation in place, we should use it to get single sign on with more
2807 services, and avoiding unneeded password / login questions. We should
2808 at least try to enable it for these services:
2811 <li
>CUPS for admins to add/configure printers and users when using
2813 <li
>Nagios for admins checking the system status.
</li
>
2814 <li
>GOsa for admins updating LDAP and users changing their passwords.
</li
>
2815 <li
>LDAP for admins updating LDAP.
</li
>
2816 <li
>Squid for users when exam mode / filtering is active.
</li
>
2817 <li
>ssh for admins and users to save a password prompt.
</li
>
2819 </ul
></li
>
2821 <li
>When we move GOsa to use Kerberos instead of LDAP bind to
2822 authenticate users, we should try to block or at least limit access to
2823 use LDAP bind for authentication, to ensure Kerberos is used when it
2824 is intended, and nothing fall back to using the less safe LDAP bind
</li
>
2826 <li
>Merge debian-edu-config and debian-edu-install. The split made
2827 sense when d-e-install did a lot more, but these days it is just an
2828 inconvenience when we update the debconf preseeding values.
</li
>
2830 <li
>Fix partman-auto to allow us to abort the installation before
2831 touching the disk if the disk is too small. This is
2832 <a href=
"http://bugs.debian.org/
653305">BTS report #
653305</a
> and the
2833 d-i developers are fine with the patch and someone just need to apply
2834 it and upload. After this is done we need to adjust
2835 debian-edu-install to use this new hook.
</li
>
2837 <li
>Adjust to new LTSP framework (boot time config instead of install
2838 time config). LTSP changed its design, and our hooks to install
2839 packages and update the configuration is most likely not going to work
2842 <li
>Consider switching to NBD instead of NFS for LTSP root, to allow
2843 the Kernel to cache files in its normal file cache, possibly speeding
2844 up KDE login on slow networks.
</li
>
2846 <li
>Make it possible to create expired user passwords that need to
2847 change on first login. This is useful when handing out password on
2848 paper, to make sure only the user know the password. This require
2849 fixes to the PAM handling of kdm and gdm.
</li
>
2851 <li
>Make GUI for adding new machines automatically from sitesummary.
2852 The current command line script is not very friendly to people most
2853 familiar with GUIs. This should probably be integrated into GOsa to
2854 have it available where the admin will be looking for it..
</li
>
2856 <li
>We should find way for Nagios to check that the DHCP service
2857 actually is working (as in handling out IP addresses). None of the
2858 Nagios checks I have found so far have been working for me.
</li
>
2860 <li
>We should switch from libpam-nss-ldapd to sssd for all profiles
2861 using LDAP, and not only on for roaming workstations, to have less
2862 packages to configure and consistent setup across all profiles.
</li
>
2864 <li
>We should configure Kerberos to update LDAP and Samba password
2865 when changing password using the Kerberos protocol. The hook was
2866 requested in
<a href=
"http://bugs.debian.org/
588968">BTS report
2867 #
588968</a
> and is now available in Wheezy. We might need to write a
2868 MIT Kerberos plugin in C to get this.
</li
>
2870 <li
>We should clean up the set of applications installed by default.
2873 <li
>reduce the number of chemistry visualisers
</li
>
2874 <li
>consider dropping xpaint
</li
>
2875 <li
>and probably more?
</li
>
2876 </ul
></li
>
2878 <li
>Some hardware need external firmware to work properly. This is
2879 mostly the case for WiFi network cards, but there are some other
2880 examples too. For popular laptops to work out of the box, such
2881 firmware need to be installed from non-free, and we should provide
2882 some GUI to do this. Ubuntu already have this implemented, and we
2883 could consider using their packages. At the moment we have some
2884 command line script to do this (one for the running system, another
2885 for the LTSP chroot).
</li
>
2888 <li
>In Squeeze, we provide KDE, Gnome and LXDE as desktop options. We
2889 should extend the list to Xfce and Sugar, and preferably find a way to
2890 install several and allow the admin or the user to select which one to
2893 <li
>The golearn tool from the goplay package make it easy to check out
2894 interesting educational packages. We should work on the package
2895 tagging in Debian to ensure it represent all the useful educational
2896 packages, and extend the tool to allow it to use packagekit to install
2897 new applications with a simple mouse click.
</li
>
2899 <li
>The Squeeze version got half a exam solution already in place,
2900 with the introduction of iptable based network blocking, but for it to
2901 be a complete exam solution the Squid proxy need to enable
2902 filtering/blocking as well when the exam mode is enabled. We should
2903 implement a way to easily enable this for the schools that want it,
2904 instead of the
"it is documented
" method of today.
</li
>
2906 <li
>A feature used in several schools is the ability for a teacher to
2907 "take over
" the desktop of individual or all computers in the room.
2908 There are at least three implementations,
2909 <a href=
"italc.sourceforge.net/
">italc
</a
>,
2910 <a href=
"http://www.itais.net/help/en/
">controlaula
</a
> og
2911 <a href=
"http://www.epoptes.org/
">epoptes
</a
> and we should pick one of
2912 them and make it trivial to set it up in a school. The challenges is
2913 how to distribute crypto keys and how to group computers in one room
2914 and how to set up which machine/user can control the machines in a
2915 given room.
</li
>
2917 <li
>Tablets and surf boards are getting more and more popular, and we
2918 should look into providing a good solution for integrating these into
2919 the Debian Edu network. Not quite sure how. Perhaps we should
2920 provide a installation profile with better touch screen support for
2921 them, or add some sync services to allow them to exchange
2922 configuration and data with the central server. This should be
2923 investigated.

>Back in
2010, Mike Gabriel showed up on the
2938 <a href=
"http://www.skolelinux.org/
">Debian Edu and Skolelinux
</a

2939 mailing list. He quickly proved to be a valuable developer, and
2940 thanks to his tireless effort we now have Kerberos integrated into the

2942 Squeeze
</a
> version.
</p
>
2944 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
2946 <p
>My name is Mike Gabriel, I am
38 years old and live near Kiel,
2947 Schleswig-Holstein, Germany. I live together with a wonderful partner
2948 (Angela Fuß) and two own children and two bonus children (contributed
2949 by Angela).
</p
>
2951 <p
>During the day I am part-time employed as a system administrator
2952 and part-time working as an IT consultant. The consultancy work
2953 touches free software topics wherever and whenever possible. During
2954 the nights I am a free software developer. In the gaps I also train in
2955 becoming an osteopath.
</p
>
2957 <p
>Starting in
2010 we (Andreas Buchholz, Angela Fuß, Mike Gabriel)
2958 have set up a free software project in the area of Kiel that aims at
2959 introducing free software into schools. The project
's name is
2960 "IT-Zukunft Schule
" (IT future for schools). The project links IT
2961 skills with communication skills.
</p
>
2963 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
2964 project?
</strong
></p
>
2966 <p
>While preparing our own customised Linux distribution for
2967 "IT-Zukunft Schule
" we were repeatedly asked if we really wanted to
2968 reinvent the wheel. What schools really need is already available,
2969 people said. From this impulse we started evaluating other Linux
2970 distributions that target being used for school networks.
</p
>
2972 <p
>At the end we short-listed two approaches and compared them: a
2973 commercial Linux distribution developed by a company in Bremen,
2974 Germany, and Skolelinux / Debian Edu. Between
12/
2010 and
03/
2011 we
2975 went to several events and met people being responsible for marketing
2976 and development of either of the distributions. Skolelinux / Debian
2977 Edu was by far much more convincing compared to the other product that
2978 got short-listed beforehand--across the full spectrum. What was most
2979 attractive for me personally: the perspective of collaboration within
2980 the developmental branch of the Debian Edu project itself.
</p
>
2982 <p
>In parallel with this, we talked to many local and not-so-local
2983 people. People teaching at schools, headmasters, politicians, data
2984 protection experts, other IT professionals.
</p
>
2986 <p
>We came to two conclusions:
</p
>
2988 <p
>First, a technical conclusion: What schools need is available in
2989 bits and pieces here and there, and none of the solutions really fit
2990 by
100%. Any school we have seen has a very individual IT setup
2991 whereas most of each school
's requirements could mapped by a standard
2992 IT solution. The requirement to this IT solution is flexibility and
2993 customisability, so that individual adaptations here and there are
2994 possible. In terms of re-distributing and rolling out such a
2995 standardised IT system for schools (a system that is still to some
2996 degree customisable) there is still a lot of work to do here
2997 locally. Debian Edu / Skolelinux has been our choice as the starting
3000 <p
>Second, a holistic conclusion: What schools need does not exist at
3001 all (or we missed it so far). There are several technical solutions
3002 for handling IT at schools that tend to make a good impression. What
3003 has been missing completely here in Germany, though, is the enrolment
3004 of people into using IT and teaching with IT.
"IT-Zukunft Schule
"
3005 tries to provide an approach for this.
</p
>
3007 <p
>Only some schools have some sort of a media concept which explains,
3008 defines and gives guidance on how to use IT in class. Most schools in
3009 Northern Germany do not have an IT service provider, the school
's IT
3010 equipment is managed by one or (if the school is lucky) two (admin)
3011 teachers, most of the workload these admin teachers get done in there
3012 spare time.
</p
>
3014 <p
>We were surprised that only a very few admin teachers were
3015 networked with colleagues from other schools. Basically, every school
3016 here around has its individual approach of providing IT equipment to
3017 teachers and students and the exchange of ideas has been quasi
3018 non-existent until
2010/
2011.
</p
>
3020 <p
>Quite some (non-admin) teachers try to avoid using IT technology in
3021 class as a learning medium completely. Several reasons for this
3022 avoidance do exist.
</p
>
3024 <p
>We discovered that no-one has ever taken a closer look at this
3025 social part of IT management in schools, so far. On our quest journey
3026 for a technical IT solution for schools, we discussed this issue with
3027 several teachers, headmasters, politicians, other IT professionals and
3028 they all confirmed: a holistic approach of considering IT management
3029 at schools, an approach that includes the people in place, will be new
3030 and probably a gain for all.
</p
>
3032 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
3033 Edu?
</strong
></p
>
3035 <p
>There is a list of advantages: international context, openness to
3036 any kind of contributions, do-ocracy policy, the closeness to Debian,
3037 the different installation scenarios possible (from stand-alone
3038 workstation to complex multi-server sites), the transparency within
3039 project communication, honest communication within the group of
3040 developers, etc.

3043 Edu?
</strong

3045 <p
>Every coin has two sides:
</p
>
3047 <p
>Technically:
<a href=
"http://bugs.debian.org/
311188">BTS issue
3048 #
311188</a
>, tricky upgradability of a Debian Edu main server, network
3049 client installations on top of a plain vanilla Debian installation
3050 should become possible sometime in the near future, one could think
3051 about splitting the very complex package debian-edu-config into
3052 several portions (to make it easier for new developers to
3053 contribute).
</p
>
3055 <p
>Another issue I see is that we (as Debian Edu developers) should
3056 find out more about the network of people who do the marketing for
3057 Debian Edu / Skolelinux. There is a very active group in Germany
3058 promoting Skolelinux on the bigger Linux Days within Germany. Are
3059 there other groups like that in other countries? How can we bring
3060 these marketing people together (marketing group A with group B and
3061 all of them with the group of Debian Edu developers)? During the last
3062 meeting of the German Skolelinux group, I got the impression of people
3063 there being rather disconnected from the development department of
3064 Debian Edu / Skolelinux.

3068 <p

</p

3070 <p
>For normal stuff I use Iceweasel/Firefox, Libreoffice.org. For
3071 serious text writing I prefer LaTeX. I use gimp, inkscape, scribus for
3072 more artistic tasks. I run virtual machines in KVM and Virtualbox.

3074 <p
>I am one of the upstream developers of X2Go. In
2010 I started the
3075 development of a Python based X2Go Client, called PyHoca-GUI.
3076 PyHoca-GUI has brought forth a Python X2Go Client API that currently
3077 is being integrated in Ubuntu
's software center.
</p
>
3079 <p
>For communications I have my own Kolab server running using Horde
3080 as web-based groupware client. For IRC I love to use irssi, for Jabber
3081 I have several clients that I use, mostly pidgin, though. I am also
3082 the Debian maintainer of Coccinella, a Jabber-based interactive

3111 <p

3112 Mathematics, and Computer Science (
"Informatik

12
3113 years (since
2000), I have been working for a comprehensive (and soon,
3114 also inclusive) school leading to all kind of general levels, such as
3115 O- or A-level (
"Abitur

3122 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
3123 project?
</strong
></p
>
3125 <p
>We had tried different Linux based school servers, when members of
3126 my local Linux User Group (LUG OWL) detected Skolelinux. I remember
3127 very well, being part of a party celebrating the Linux New Media Award
3128 (
"Best Newcomer Distribution
", also nominated: Ubuntu) that was given
3129 to Skolelinux at Linux World Exposition in Frankfurt,
2005 (IIRC). Few
3130 months later, I had the chance to join a developer meeting in Ulsrud
3131 (Oslo) and to hand out the award to Knut Yrvin and others. For more
3132 than
7 years, Skolelinux is part of our schools infrastructure, namely
3133 our main server (tjener), one LTSP (today without thin clients), and
3134 approximately
50 work stations. Most of these have the option to boot a
3135 locally installed Skolelinux image. As a consequence, I joined quite
3136 a few events dealing with free software or Linux, and met many Debian
3137 (Edu) developers. All of them seemed quite nice and competent to me,
3138 one more reason to stick to Skolelinux.

3143 <p
>Debian driven, you are given all the advantages of a community
3144 project including well maintained updates. Once, you are familiar with
3145 the network layout, you can easily roll out an entire educational
3146 computer infrastructure, from just one installation media. As only
3147 free software (FOSS) is used, that supports even elderly hardware,
3148 up-sizing your IT equipment is only limited by space (i.e. available
3149 labs). Especially if you run a LTSP thin client server, your
3150 administration costs tend towards zero.
</p
>
3152 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
3153 Edu?
</strong
></p
>
3155 <p
>While Debian
's stability has loads of advantages for servers, this
3156 might be different in some cases for clients: Schools with unlimited
3157 budget might buy new hardware with components that are not yet
3158 supported by Debian stable, or wish to use more recent versions of
3159 office packages or desktop environments. These schools have the
3160 option to run Debian testing or other distributions - if they have the
3161 capacity to do so. Another issue is that Debian release cycles
3162 include a wide range of changes; therefor a high percentage of human
3163 power seems to be absorbed by just keeping the features of Skolelinux
3164 within the new setting of the version to come. During this process,
3165 the cogs of Debian Edu are getting more and more professional,
3166 i.e. harder to understand for novices.

3184 <li

's public schools
3185 there are more or less fixed budgets for IT equipment (including
3186 licenses), so schools won

3188 share among German Skolelinux schools.

3225 intervjurunde av folkene bak Skolelinux-løsningen. Jeg har kjent Alf
3226 Tonny siden vi møttes som barn på påskefjellet i Ofoten, og ble
3227 gledelig overrasket da han dukket opp i Skolelinux-prosjektet etter å
3228 ikke ha sett noe til ham på mange år.

>Hvem er du, og hva driver du med til daglig?

3232 <p
>Jeg er utdannet kokk av yrke, og har utøvet yrket i
12 år. Men
3233 etter at ryggen sa takk før seg, studerte jeg nettverksadministrasjon
3234 ved Næringsakademiet i Bergen årene
2008-
2009 slik at jeg kunne
3235 forfølge en av mine største interesser - data. Til daglig jobber jeg
3236 ved
<a href=
"http://www.narvikskolen.no/parken/
">Parken
3237 ungdomsskole
</a
> med å drifte skolens PC-er. Har også litt
3238 musikkundervisning.
</p
>
3240 <p
>Mitt mål er å bevisstgjøre musikklærene mulighetene med de frie
3241 programmene som finnes i Skolelinux, blant annet Rosegarden.
</p
>
3243 <p
>Har i mange år drevet med musikk og en av grunnen til at Rosegarden
3244 falt i smak for min del, var fordi denne fungere og ligner mest på
3245 Windows-programmet (cubase) jeg jobbet mye med da jeg i mine yngre
3246 dager var «Windows fanatiker». Ble introdusert til Linux av en kompis
3247 av meg for omtrent
14 år siden, og har bare blitt mer og mer glad i
3248 dette operativsystemet.
</p
>
3250 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
3252 <p
>Da jeg ble sykemeldt fra min gamle jobb, og måtte omskoleres,
3253 havnet jeg i
2007 sammen med Viggo Fedreheim på IKT-avdelingen i
3254 Narvik kommune, der ble jeg for første gang introdusert til
3255 Skolelinuxprosjektet.
</p
>
3257 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
3259 <p
>Skolelinux er enkelt å holde i drift og masse flotte programmer som
3260 geogebra, ktouch og kgeografi følger med pakken. Man kan ta i bruk
3261 gamle PC-er igjen, slik at skoler med dårlig råd får opp en brukbar
3262 PC-park. PC-er som er ca
6-
9 år gamle fungere tilfredstillende, bare
3263 de har
512 MB RAM eller mer.
</p
>
3265 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
3267 <p
>Ulempene er at noen av de pedagogiske programmene som lærene ønsker
3268 å bruke fungere dårlig med Linux. Mye pga. av at disse programmene
3269 blir ikke laget til Linuxbaserte operativsystemer.
</p
>
3271 <p
>Video- og bilde-redigering har dessverre en del mangler, mange av
3272 programmene har en tendens til og krasje. Det gjelder blant annet
3273 <a href=
"http://www.kdenlive.org/
">kdenlive
</a
> og
3274 <a href=
"http://www.openshotvideo.com/
">openshot
</a
>, for å nevne
3275 noen. De er ikke stabile nok. Når elevene kommer med filmsnutter de
3276 ønsker og jobbe med, så godtar ikke programmene filene, og når elevene
3277 jobber med redigering bare krasjer programmene uten forvarsel. Det er
3278 for vanskelig å få noe som bare fungerer ut av boksen her. Når en elev
3279 plugger inn et videokamera eller fotoapparat så er det alltid noe som
3280 ikke vil fungere. Programmene godtar ikke format, godtar ikke
3281 kameraet, osv., osv. Det er dessverre med på og dra ned en positiv
3282 opplevelse av bruk av fri programvare.
</p
>
3284 <p
>Man må ofte bruke flere en et video redigerings program før og få
3285 fullført en ønsket oppgave.
</p
>
3287 <p
>Eksempel:
</p
>
3289 <p
>Hvis det ene programmet ikke vil ta i mot videofilen klarer et
3290 annet det, men det programmet som klarer det kan ikke gjøre de samme
3291 oppgavene som det programmet som ikke ville ta i mot filen,
3292 Tilsvarende er det med foto, man må bruke flere programmer for å få
3293 et ferdig resultat. Til dags dato har jeg enda ikke funnet et video-
3294 og fotoprogram som kan tilfredstillende fullføre en oppgave.
</p
>
3296 <p
>Så man kan klare og fullføre en oppgave, men i verste fall må man
3297 innom
3-
4 programmer for å få det til. Så jeg har enda ikke til dags
3298 dato sett at et program fungere
100% til alt.
</p
>
3300 <p
>Det programmet jeg har best erfaring til er
3301 <a href=
"http://cinelerra.org/
">cinelerra
</a
>, men dessverre har det
3302 også tendenser og krasje av og til uten grunn.
</p
>
3304 Lydsystemet kan også være et mareritt. Konkret snakker jeg om når du
3305 bruker for eksempel et smartboard, så følger det med USB-lydkort på
3306 disse. Problemet ligger her i at systemet ikke vil velge rett
3307 lydkort, så man må inn med padevchooser for å sette opp PulseAudio
3308 til og velge at USB-lydkortet skal brukes. Det blir for tungvindt for
3309 lærene, de ønsker at ting skal fungere med en gang. (min løsning på
3310 det problemet ble at jeg måtte deaktivere lydkortet som fantes på
3311 maskinen) men da må man bestandig slå på smartboard-tavla.
3313 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
3315 Programmene jeg bruker mest av er: Rosegarden, jack, qsynth, audacity,
3316 k3b, openttd og libreoffice.
3318 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
3319 skoler til å ta i bruk fri programvare?
</strong
></p
>
3321 Jeg tror det må bevisstgjøring av Skolene til, dvs. reklamere høylytt
3322 og fortelle og vise de andre skolene at frie programvarer faktisk
3323 fungere. Jeg trur faktisk mange ikke vet at det finnes frie

>It has been a few busy weeks for me, but I am finally back to
3334 publish another interview with the people behind
3335 <a href=
"http://www.skolelinux.org/
">Debian Edu and Skolelinux
</a
>.
3336 This time it is one of our German developers, who have helped out over the
3337 years to make sure both a lot of major but also a lot of the minor
3338 details get right before release.
3340 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
3342 <p
>My name is Jürgen Leibner, I
'm
49 years old and living in
3343 Bielefeld, a town in northern Germany. I worked nearly
20 years as
3344 certified engineer in the department for plant design and layout of an
3345 international company for machinery and equipment. Since
2011 I
'm a
3346 certified technical writer (tekom e.V.) and doing technical
3347 documentations for a steam turbine manufacturer. From April this year
3348 I will manage the department of technical documentation at a
3349 manufacturer of automation and assembly line engineering.
</p
>
3351 <p
>My first contact with linux was around
1993. Since that time I used
3352 it at work and at home repeatedly but not exclusively as I do now at
3353 home since
2006.
</p
>
3355 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
3356 project?
</strong
></p
>
3358 <p
>Once a day in the early year of
2001 when I wanted to fetch my
3359 daughter from primary school, there was a teacher sitting in the
3360 middle of
20 old computers trying to boot them and he failed. I helped
3361 him to get them booting. That was seen by the school director and she
3362 asked me if I would like to manage that the school gets all that old
3363 computers in use. I answered:
"Yes
".
</p
>
3365 <p
>Some weeks later every of the
10 classrooms had one computer
3366 running Windows98. I began to collect old computers and equipment as
3367 gifts and installed the first computer room with a peer-to-peer
3368 network. I did my work at school without being payed in my spare time
3369 and with a lot of fun. About one year later the school was connected
3370 to Internet and a local area network was installed in the school
3371 building. That was the time to have a server and I knew it must be a
3372 Linux server to be able to fulfil all the wishes of the teachers and
3373 being able to do this in a transparent and economic way, without extra
3374 costs for things like licence and software. So I searched for a
3375 school server system running under Linux and I found a couple of
3376 people nearby who founded
'skolelinux.de
'. It was the Skolelinux
3377 prerelease
32 I first tried out for being used at the school. I
3378 managed the IT of that school until the municipal authority took over
3379 the IT management and centralised the services for all schools in
3380 Bielefeld in December of
2006.

3382 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
3383 Edu?
</strong
></p
>
3385 <p
>When I
'm looking back to the beginning, there were other advantages
3386 for me as today.
</p
>
3388 <p
>In the past there were advantages like:
</p
>
3392 <li
>I don
't need to buy it so it generates no costs to the school as
3393 they had little money to spent for computers and software.
</li
>
3395 <li
>It has a licence which grands all rights to use it without
3398 <li
>It was more able to fit all requirements of a server system for
3399 schools than a Microsoft server system, even if there are only Windows
3400 clients because of it
's preconfigured overall concept of being a
3401 infrastructure solution and community for schools, not only a
3404 <li
>I was able to configure the server to the needs of the
3407 </ul
></p
>
3409 <p
>Today some of the advantages has been lost, changed or new ones
3410 came up in this way:
</p
>
3414 <li
>Most schools here do have money to buy hardware and software
3417 <li
>They are today mostly managed from central IT departments which
3418 have own concepts which often do not fit to Debian Edu concepts
3419 because they are to close to Microsoft ideology.
</li
>
3421 <li
>With the Squeeze version of Debian Edu which now uses GOsa² for
3422 management I feel more able to manage the daily tasks than with the
3423 interfaces used in the past.
</li
>
3425 <li
>It is more modular than in the past and fits even better to the
3426 different needs.
</li
>
3428 <li
>The documentation is usable and gets better every day.
</li
>
3430 <li
>More people than ever before are using Debian Edu all over the
3431 world and so the community, which is an very important part I think,
3432 is sharing knowledge and minds.
</li
>
3434 <li
>Most, maybe all, of the technical requirements for schools are
3435 solved today by Debian Edu.
</li
>
3437 </ul
></p
>
3439 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
3440 Edu?
</strong
></p
>
3444 <li
>There are too few IT companies able to integrate Debian Edu into
3445 their product portfolio for serving schools with concepts or even
3446 whole municipality areas.
</li
>
3448 <li
>Debian Edu has beside other free and open software projects not
3449 enough lobbyists which promote free and open software to
3450 politicians.
</li
>
3452 <li
>Technically there are no disadvantages I
'm aware of.
</li
>
3454 </ul
></p
>
3456 <p
><strong
>Which free software do you use daily?
</strong
></p
>
3458 <p
>I use Debian stable on my home server and on my little desktop
3459 computer. On my laptop I use Debian testing/sid. The applications I
3460 use on my laptop and my desktop are Open/Libre-office, Iceweasel,
3461 KMail, DigiKam, Amarok, Dolphin, okular and all the other programs I
3462 need from the KDE environment. On console I use newsbeuter, mutt,
3463 screen, irssi and all the other famous and useful tools.
</p
>
3465 <p
>My home server provides mail services with exim, dovecot, roundcube
3466 and mutt over ssh on the console, file services with samba, NFS,
3467 rsync, web services with apache, moinmoin-wiki, multimedia services
3468 with gallery2 and mediatomb and database services with MySQL for me
3469 and the whole family. I probably forgot something.

><strong
>Which strategy do you believe is the right one to use to
3472 get schools to use free software?

>Da jeg googlet etter noe annet kom jeg tilfeldigvis over
3486 <a href=
"http://www.duo.uio.no/sok/work.html?WORKID=
58309">en
3487 hovedfagsoppgave
</a
> ved Universitetet i Oslo som diskuterer verdien
3488 av GPLs fire friheter for brukerne av IT-systemer. Jeg ble fascinert
3489 over det som presenteres der. Her er sammendraget:
</p
>
3491 <p
><blockquote
>
3493 <p
>Motivasjonen til å skrive denne oppgaven er en personlig undring
3494 over hvorfor det primært, og ofte eksklusivt, fokuseres på det
3495 økonomiske aspektet ved utredninger om fri programvare er et godt valg
3496 for det offentlige. Fri og produsenteid programvare bygger på
3497 fundamentalt forskjellige ideologier som kan ha implikasjoner utover
3498 økonomiske kostnader. Kunnskapskulturen som er med på å definere fri
3499 programvare er basert på åpenhet, og er en verdi i seg selv.
</p
>
3501 <p
>Oppgavens tema er programvarelisensen GPL og frihet. GPL-lisensiert
3502 programvare gir visse friheter i forhold til produsenteid
3503 programvare. Mitt spørsmål er om, og eventuelt i hvilken utstrekning,
3504 disse frihetene blir benyttet av ulike brukere og hvordan de
3505 manifesterer seg for disse brukerne. Sentrale spørsmål i oppgaven
3509 <li
>Hvordan fordeles handlekraft gjennom lisensieringen av programvaren?
</li
>
3510 <li
>Hvilke konsekvenser har programvarelisensen for de ulike brukere?
</li
>
3513 <p
>Fri programvare gir blant annet brukeren mulighet til å studere og
3514 modifisere kildekoden. Denne formen for frihet erverves gjennom
3515 kunnskap og krever at brukeren også er en ekspert. Hva skjer med
3516 frihetene til GPL når sluttbrukeren er en annen? Dette diskuteres i
3517 dialog med informantene.
</p
>
3519 <p
>Jeg har i denne oppgaven samlet inn intervjudata fra IKT-ansvarlige
3520 ved grunnskolene i Nittedal kommune, driftsansvarlig og IKT-veilederen
3521 for skolene i kommunen, samt IKT-koordinator for utdanning i Akershus
3522 fylkeskommune og bokmåloversettere av OpenOffice.org. Den empiriske
3523 delen av oppgaven er delt inn i to seksjoner; den første omhandler
3524 operativsystemet Skolelinux, den andre kontorprogrampakken
3525 OpenOffice.org.
</p
>
3527 <p
>Som vi vil se gir GPL lokal frihet og kontroll gjennom omfordeling
3528 av makt fra produsent til bruker. Brukerens makt analyseres gjennom
3529 begrepene brukermedvirkning og handlingsfrihet. Det blir også lagt
3530 vekt på strukturelle forhold rundt bruken av teknologi, og spesielt de
3531 økonomiske begrepene nettverkseksternaliteter, innlåsing og
3532 stiavhengighet. Dette er begreper av spesiell nytte når objektet som
3533 omsettes eller distribueres er et kommunikasjonsprodukt, fordi verdien
3534 til et slikt gode for en potensiell bruker avhenger av antall
3535 eksisterende brukere av godet. I tilknytning til denne problematikken
3536 inneholder oppgaven også en diskusjon rundt åpne standarder og
3539 <p
>Oppgaven konkluderer med at de «fire frihetene» som GPL-lisensen er
3540 laget for å beskytte er av avgjørende betydning for bruken av
3541 OpenOffice.org og Skolelinux, i Akershus fylkeskommune såvel som i
3542 skolene i Nittedal. Distribusjonen av handlekraft er ikke helt
3543 symmetrisk. Det er først og fremst de profesjonelle utviklerne i
3544 Skolelinux som direkte kan nyttiggjøre seg friheten til å endre kode,
3545 mens en sluttbruker som Nittedal kommune nyttiggjør seg den økonomiske
3546 friheten til å kunne distribuere programmene. Det er imidlertid også
3547 slik at ingen aktør klarer seg uten alle disse «frihetene».

3565 setting together all the pieces. This time I present to you Andreas
3566 Mundt, who have been part of the technical development team several
3567 years. He was also a key contributor in getting GOsa and Kerberos set

3574 <p
>My name is Andreas Mundt, I grew up in south Germany. After
3575 studying Physics I spent several years at university doing research in
3576 Quantum Optics. After that I worked some years in an optics company.
3577 Finally I decided to turn over a new leaf in my life and started
3578 teaching
10 to
19 years old kids at school. I teach math, physics,
3579 information technology and science/technology.

3584 <p
>Already before I switched to teaching, I followed the Debian Edu
3585 project because of my interest in education and Debian. Within the
3586 qualification/training period for the teaching, I started
3587 contributing.

</strong

3592 <p
>The advantages of Debian Edu are the well known name, the
3593 out-of-the-box philosophy and of course the great free software of the
3594 Debian Project!

3599 <p
>As every coin has two sides, the out-of-the-box philosophy has its
3600 downside, too. In my opinion, it is hard to modify and tweak the
3601 setup, if you need or want that. Further more, it is not easily
3602 possible to upgrade the system to a new release. It takes much too
3603 long after a Debian release to prepare the -Edu release, perhaps
3604 because the number of developers working on the core of the code is
3605 rather small and often busy elsewhere.

3620 <p

3621 Especially in combination with ignorant government employees and
3622 politicians, this works out great for the
"market-leader
". The school
3623 administration here in Baden-Wuerttemberg is occupied by that vendor.
3624 Documents have to be prepared in non-free, proprietary formats. Even
3625 free browsers do not work for the school administration. Publishers
3626 of school books provide software only for proprietary platforms.
</p
>
3628 <p
>To change this, political work is very important. Parts of the
3629 political spectrum have become aware of the problem in the last years.
3630 However it takes quite some time and courageous politicians to
'free
'
3631 the system. There is currently some discussion about
"Open Data
" and
3632 "Free/Open Standards
". I am not sure if all the involved parties have
3633 a clue about the potential of these ideas, and probably only a
3634 fraction takes them seriously. However it might slowly make free
3635 software and the philosophy behind it more known and popular.

>Recently I have spent time with
3702 <a href=
"http://www.slxdrift.no/
">Skolelinux Drift AS
</a
> on speeding
3703 up a
<a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>
3704 Lenny installation using LTSP diskless workstations, and in the
3705 process I discovered something very surprising. The reason the KDE
3706 menu was responding slow when using it for the first time, was mostly
3707 due to the way KDE find application icons. I discovered that showing
3708 the Multimedia menu would cause more than
20 000 IP packages to be
3709 passed between the LTSP client and the NFS server. Most of these were
3711 NFS LOOKUP calls, resulting in a NFS3ERR_NOENT response. Because the
3712 ping times between the client and the server were in the range
2-
20
3713 ms, the menus would be very slow. Looking at the strace of kicker in
3714 Lenny (or plasma-desktop i Squeeze - same problem there), I see that
3715 the source of these NFS calls are access(
2) system calls for
3716 non-existing files. KDE can do hundreds of access(
2) calls to find
3717 one icon file. In my example, just finding the mplayer icon required
3718 around
230 access(
2) calls.
</p
>
3720 <p
>The KDE code seem to search for icons using a list of icon
3721 directories, and the list of possible directories is large. In
3722 (almost) each directory, it look for files ending in .png, .svgz, .svg
3723 and .xpm. The result is a very slow KDE menu when /usr/ is NFS
3724 mounted. Showing a single sub menu may result in thousands of NFS
3725 requests. I am not the first one to discover this. I found a
3726 <a href=
"https://bugs.kde.org/show_bug.cgi?id=
211416">KDE bug report
3727 from
2009</a
> about this problem, and it is still unsolved.
</p
>
3729 <p
>My solution to speed up the KDE menu was to create a package
3730 kde-icon-cache that upon installation will look at all .desktop files
3731 used to generate the KDE menu, find their icons, search the icon paths
3732 for the file that KDE will end up finding at run time, and copying the
3733 icon file to /var/lib/kde-icon-cache/. Finally, I add symlinks to
3734 these icon files in one of the first directories where KDE will look
3735 for them. This cut down the number of file accesses required to find
3736 one icon from several hundred to less than
5, and make the KDE menu
3737 almost instantaneous. I
'm not quite sure where to make the package
3738 publicly available, so for now it is only available on request.
</p
>
3740 <p
>The bug report mention that this do not only affect the KDE menu
3741 and icon handling, but also the login process. Not quite sure how to
3742 speed up that part without replacing NFS with for example NBD, and
3743 that is not really an option at the moment.

3772 user community, and this time I managed to get hold of Wolfgang
3773 Schweer, a valuable contributor to the project from Germany.
3775 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
3777 <p
>I
've studied Mathematics at the university
'Ruhr-Universität
' in
3778 Bochum, Germany. Since
1981 I
'm working as a teacher at the school
3779 "<a href=
"http://www.westfalenkolleg-dortmund.de/
">Westfalen-Kolleg
3780 Dortmund
</a
>", a second chance school. Here, young adults is given
3781 the opportunity to get further education in order to do the school
3782 examination
'Abitur
', which will allow to study at a university. This
3783 second chance is of value for those who want a better job perspective
3784 or failed to get a higher school examination being teens.
</p
>
3786 <p
>Besides teaching I was involved in developing online courses for a
3787 blended learning project called
'abitur-online.nrw
' and in some other
3788 information technology related projects. For about ten years I
've been
3789 teacher and coordinator for the
'abitur-online
' project at my
3790 school. Being now in my early sixties, I
've decided to leave school at
3791 the end of April this year.
</p
>
3793 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
3794 project?
</strong
></p
>
3796 <p
>The first information about Skolelinux must have come to my
3797 attention years ago and somehow related to LTSP (Linux Terminal Server
3798 Project). At school, we had set up a network at the beginning of
1997
3799 using Suse Linux on the desktop, replacing a Novell network. Since
3800 2002, we used old machines from the city council of Dortmund as thin
3801 clients (LTSP, later Ubuntu/Lessdisks) cause new hardware was out of
3802 reach. At home I
'm using Debian since years and - subscribed to the
3803 Debian news letter - heard from time to time about Skolelinux. About
3804 two years ago I proposed to replace the (somehow undocumented and only
3805 known to me) system at school by a well known Debian based system:
3806 Skolelinux.
</p
>
3808 <p
>Students and teachers appreciated the new system because of a
3809 better look and feel and an enhanced access to local media on thin
3810 clients. The possibility to alter and/or reset passwords using a GUI
3811 was welcomed, too. Being able to do administrative tasks using a GUI
3812 and to easily set up workstations using PXE was of very high value for
3813 the admin teachers.
</p
>
3815 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
3816 Edu?
</strong
></p
>
3818 <p
>It
's open source, easy to set up, stable and flexible due to it
's
3819 Debian base. It integrates LTSP out-of-the-box. And it is documented!
3820 So it was a perfect choice.
</p
>
3822 <p
>Being open source, there are no license problems and so it
's
3823 possible to point teachers and students to programs like
3824 OpenOffice.org, ViewYourMind (mind mapping) and The Gimp. It
's of
3825 high value to be able to adapt parts of the system to special needs of
3826 a school and to choose where to get support for this.

3828 <p

>What do you see as the disadvantages of Skolelinux/Debian
3829 Edu?

></p
>
3831 <p
>Nothing yet.
</p
>
3833 <p
><strong
>Which free software do you use daily?
</strong
></p
>
3835 <p
>At home (Debian Sid with Gnome Desktop): Iceweasel, LibreOffice,
3836 Mutt, Gedit, Document Viewer, Midnight Commander, flpsed (PDF
3837 Annotator). At school (Skolelinux Lenny): Iceweasel, Gedit,
3838 LibreOffice.
</p
>
3840 <p
><strong
>Which strategy do you believe is the right one to use to
3841 get schools to use free software?
</strong
></p

3843 <p
>Some time ago I thought it was enough to tell people about it. But
3844 that doesn
't seem to work quite well. Now I concentrate on those more
3845 interested and hope to get multiplicators that way.

3863 <p
>Det er store forskjeller på skolenes digitale tilstand, viser
3864 undersøkelsen Monitor
2011 som er laget på oppdrag fra
3865 Kunnskapsdepartementet. Dette har ført til debatt om PC-tilgangen i
3866 skolen, og om de med Linux i skolen gjør det bedre bedre eller
3867 dårligere enn snittet i landet.
</p
>
3869 <p
>Nå har vi tallene. Skoler med Linux har
36% større PC-tetthet en
3870 landsgjennomsnittet. På spørsmål hvorfor skoler med Linux har større
3871 PC-tetthet, observerer Paul Reidar Løsnesløkken som er IKT-konsulent i
3872 Nord-Odal:
</p
>
3874 <p
><blockquote
>"Vi erfarer at klienter med Skolelinux har god funksjon
3875 til de er
8 til
10 år gamle. Dette er omtrent dobbelt så lenge som
3876 andre løsninger, og skolene får mer datautstyr for
3877 pengene.
"</blockquote
></p
>
3879 <p
>Undersøkelsen baserer seg på
56 skoler som har gjort det offentlig
3880 at de kjører Skolelinux eller annen Linux-utgave. De kan også ha PC-er
3881 med Windows i skolenettet. Når en sammenligner PC-tetthetene på
3882 skolene i kommunene Flora, Harstad, Kongsvinger, Narvik, Nittedal,
3883 Nord-Odal og Randaberg, er det i snitt
2,
28 elev pr. PC på skolene med
3884 Linux. På landsbasis er det
3.11 elev per PC i grunnskolen, i følge
3885 side
95 i Monitor-rapporten for
2011. Målingen viser dermed
36% større
3886 PC-tetthet i skoler med Linux.

3890 <p
>Skolelinux har til hensikt å gi alle barn full tilgang til
3891 skoleaktuelle dataprogram på sitt eget morsmål. Derfor følger det med
3892 godt over
100 skoleaktuelle programmene laget for læring. De fleste
3893 programmene er oversatt til over
50 språk. Elevene skal også kunne
3894 studere alle sider av dataprogrammene. Derfor følger også kildekode
3895 med. Elever med interesse kan lære av eksperter som har laget
3896 systemet. Dette med enkelt programmering i læreprogram som KTurtle,
3897 til profesjonelle verktøy som Qt Creator eller Java.

3899 <p
>Skolelinux er laget for sentralisert drift, der alt teknisk
3900 administrasjon av alle skolene kan gjøres sentralt fra kommunehuset
3901 eller sentralt i en region. F.eks. drifter to-tre personer
70.000
3902 skoledatamaskiner på
200 skoler i delstaten Extremadura i
3903 Spania. Etter velykket bruk av Debian Edu i skolen, legger delstaten
3904 over til Debian på
40.000 datamaskiner i administrasjonen. Det er idag

3945 denne gangen høre fra en IKT-ansvarlig som har brukt Skolelinux i
3946 mange år, og vært storfornøyd med erfaringene så langt.

3948 <p

>Hvem er du, og hva driver du med til daglig?

3950 <p

42 år. Jeg er ansatt hos
3951 <a href=
"http://www.sandskole.no/
">Sand skole

3952 og har stort sett vært det siden
1990. Jeg er IKT ansvarlig ved
3953 skolen i
40% stilling –
10% undervisning – musikk.
</p
>
3955 <p
>Ved skolen er det ca
100 elever og ca
18 lærere +
4 assistenter i
3956 hele og delte stillinger. Alle lærerne har bærbar PC (dessverre med
3957 Win Vista) – assistenter har tilgang til egne. Vi benytter Fronter i
3958 det daglige arbeidet. Vi har ca
90 elevmaskiner som fungerer til
3959 daglig opp mot Linux server (XFCE) som driftes av
3960 <a href=
"http://www.bzz.no/
">BzzWare AS
</a
> via nett. Maskinparken
3961 består kun av brukt utstyr for elevene – og noe av dette begynner å
3962 bli vel gammelt selv som halvtykke klienter.
</p
>
3964 <p
><strong
>Hvordan kom du i kontakt med
3965 Skolelinux-prosjektet?
</strong
></p
>
3967 <p
>Vi kom første gang i kontakt med Skolelinux rundt
1997. Den gang
3968 var det oppstart-disketter i hver maskin, ikke mulighet for lyd og
3969 video, gamle nettverkskort og mye plundring. Vi hadde en ihuga
3970 forelder med som pådriver, forsker og inspirator for hele opplegget.
3971 Selv ante jeg knapt at Skolelinux fantes, men han var av den
3972 utforskende typen, og fikk både meg og skolelederen i trua på at dette
3973 var ting som kunne fungere. Etter dette har det gått gradvis
3974 framover; flere maskiner er hentet inn gjennom bl.a
3975 <a href=
"http://www.greentech.no/
">Greentech
</a
> og utrangert utstyr
3976 fra høgskole / Avinor og private givere. Når maskinene ble for trege
3977 for nye Windows-versjoner, sto vi klare til å putte dem i nettverket
3978 vårt. Dette betyr at vi i dag har
1:
1 dekning av maskiner på
3979 ungdomstrinnet og bedre enn
1:
2 på barnetrinnet. Dette er vi veldig
3980 fornøyd med, og vi kan ikke se for oss hverdagen som ville vært
3981 alternativet ved bruk av Windows med sine lisenser pr. Bruker/maskin.
3982 Da ville vi nok vært tilbake til
1-
2 maskiner pr klasserom med de
3983 negative konsekvenser det ville hatt for undervisningsformene våre. Vi
3984 kan ha en hel klasse i prosjektjobbing eller individuell jobbing
3985 samtidig – vi kan avholde tentamen og eksamen uten
3986 logistikkproblemer.

3988 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
3990 Hvor skal jeg begynne... Stabiliteten er et nøkkelord - det bare
3991 virker. Har du først fått en server med Skolelinux opp og gå, så må
3992 det en maskinarefeil eller sabotasje til for å stoppe den. Det at man
3993 kan bruke eldre maskiner som normalt sett ville gått på dynga, er også
3994 glimrende - billig for skoler med dårlig økonomi og bra for miljøet
3995 siden vi gjenbruker utstyr i stedet for å skaffe nytt. Vi ville aldri
3996 hatt mulighet til å operere med det maskinantallet vi har pr i dag
3997 hvis det ikke var for Skolelinux - så tilgjengelighet er et annet
3998 nøkkelord. Et tredje moment er sikkerhet og brukertilgang. Alle
3999 brukerer opererer med egne brukernavn og passord, samt egne
4000 brukerområder som kan tilpasses for både enbrukertilgang og for
4001 samarbeid med andre.
4003 Elever har godt av å se at det finnes andre alternativer enn de som
4004 storindustrien selger på lisensbasis - på den måten trenes de opp til
4005 å se flere muligheter og å foreta valg ut fra flere opsjoner.
4007 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
4009 <p
>Ulempene med Skolelinux er nok utbredelsen og mangelen på kjennskap
4010 til dette i skolenorge. De som skal ta økonomiske avgjørelser rynker
4011 på nesen og vil gå for det kjente og «sikre» selv om det koster mye
4012 mer. Man får rett og slett litt hetta av å ikke kunne noe – og unngår
4013 dette for enhver pris.
</p
>
4015 <p
>I tillegg er mye av linux-systemet administrert av tekstkommandoer
4016 og er lite intuitiv/visuell for oss som ikke er «inne i»
4017 kildekodene». Så problemet er nok mye godt at de som
4018 utarbeider/drifter Skolelinux ikke helt klarer å sette seg ned på
4019 skoleadministratorens nivå når det gjelder problemer og
4020 utfordringer. Men dette er nok en utfordring alle administratorer
4021 sliter med uansett OS.
</p
>
4023 <p
>Derfor har vi valgt å støtte oss til BzzWare AS for assistanse i
4024 drifta slik at jeg har kunnet konsentrere meg mer om kabling, skifting
4025 av komponenter, veiledning av lærere og elever, vedlikehold av
4026 skrivere og annen daglig drift.
</p
>
4028 <p
>Elevene mestrer Skolelinux helt fint. Så lenge Internett
4029 (Iceweasel) og Libreoffice (Openoffice) fungerer er
90% av
4030 skolehverdagen velfungerende. I tillegg brukes jo en del av den
4031 pedagogiske programpakken bla. i forhold til matematikk og geografi,
4032 men det er såpass mye bra på nett om dagen, så disse programmene er
4033 mer som krydder å regne.
</p
>
4035 <p
>Jeg skulle ønske neste versjon av Skolelinux kunne komme litt
4036 mindre stappet med programmer, for halvparten blir aldri brukt, eller
4037 fungerer ikke uansett. Hva med et pedagogisk panel av lærere/IKT
4038 ansvarlige som kunne sagt: disse programmene skal være standard, så
4039 får resten være slike man kan legge til ved behov – det kan lett bli
4040 en jungel å bevege seg i.
</p
>
4042 <p
>Jeg ønsker meg også en mer grafisk versjon av
4043 <a href=
"http://bzz.no/lwat/trac/trac.cgi
">Lwat
</a
> hvor man kan krysse
4044 ut de som f.eks ikke skal ha internett-tilgang en dag pga
4045 eksamen/tentamen, samt en noe enklere brannmurløsning hvor man kan
4046 stenge for en del (få) sider på en enkel måte. Jeg liker godt
4047 Skolelinux sin ideologi om at filteret skal trenes i hodet på eleven –
4048 men av og til skulle jeg ønske at f.eks Facebook og Youtube kunne vært
4049 koblet vekk en periode for å få bedre utnyttelse av tid og
4050 ressurser. Disse to nettstedene er nok mye av årsaken til at mange
4051 lærere holder igjen databruken noe mer enn man kunne ønske.
</p
>
4053 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
4055 Jeg benytter nesten bare fri programvare til daglig. LibreOffice,
4056 Iceweasel (Firefox), Thunderbird til e-post og Gimp til
4057 bildebehandling. Vi har PHP-Nuke-oppsatt hjemmeside. Det eneste som
4058 jeg ikke har fått helt til enda er videoredigering - her må man vel
4059 innrømme at Mac er hakket over, men da er vi igjen over på å se hva
4060 som egner seg best, og ta valg ut fra det. Folk flest lever i
4061 villfarelsen om at regneark HETER Excel og tekstbehandling HETER
4062 Word. Dette er en misforståelse som jeg bruker mye energi på å
4063 diskutere og
"åpne sinn
" på Microsoft-slaver. Dessverre er det mange
4064 IKT-ansvarlige som også har låst seg på at det eneste saliggjørende er
4065 Bill G sine produkter.
4067 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
4068 skoler til å ta i bruk fri programvare?
</strong
></p
>
4070 <p
>For å komme lenger i utbredelsen av Skolelinux tror jeg det må mer
4071 fram i nasjonale medier, samt komme bedre fram hva økonomien i dette
4072 valget vil være – samt mulighetene. Fri programvare er en berikelse og
4073 gjør oss i stand til å utføre arbeidet i skolen uten å måtte legge
4074 igjen tusener på tusener i Bill Gates lomme.. Få ETT nettsted med
4075 forståelig veiledning av installasjon/oppgradering og ETT forum med
4076 konkrete feilrettinger og problemer, så tror jeg vi kunne kommet et
4077 par skritt framover. Ellers tror jeg bare at ildsjelene må fortsette å
4078 skinne – kanskje flere enn oss følger etter på veien.

>Den siste uka har det vært en del skriverier om hvor store
4113 forskjeller det er mellom skolene når det gjelder digital kompetanse.
4115 <a href=
"http://www.digi.no/
891660/bekymret-for-it-i-skolen
">oppslaget
4116 i Digi
</a
>. Diskusjonen fikk meg til å bli litt nysgjerrig på om
4117 Linux-skoler har større PC-tettet enn snittet i landet. Grunnlaget
4118 for diskusjonen har vært undersøkelsen
4119 <a href=
"https://iktsenteret.no/ressurser/monitor-
2011-skolens-digitale-tilstand
">Monitor
4120 2011</a
>, som bruker informasjon fra
4121 <a href=
"https://www.wis.no/gsi
">Grunnskolens Informasjonssystem
</a
>
4122 (GSI). GSI-data kan lastes ned fra web og jeg lastet ned en Excel-fil
4123 (intet åpen standard-valg tilgjengelig) med navn på alle skoler,
4124 hvilke kommune de befinner seg i og hvor mange elever pr. elev-PC de
4125 har rapportert inn. For å få en ide om svaret trenger jeg deretter å
4126 vite hvilke skoler i landet som bruker Linux, slik at jeg kan slå dem
4127 opp i GSI og finne ut hvor stor PC-tetthet de har.
</p
>
4129 <p
>Jeg vet om skoler i Balsfjord, Flora, Harstad, Kongsvinger, Narvik,
4130 Nittedal, Nord-Odal, Randaberg og Sunndal som bruker Skolelinux eller
4131 andre Linux-varianter. Jeg tror det er flere enn de
56 skolene jeg
4132 har klart å identifisere de siste dagene, men har ikke klart å få det
4133 bekreftet med offentlige kilder.
</p
>
4135 <p
>Monitor
2011-rapporteres side
95 forteller at det
"ifølge GSI
4136 (
20120-
2011) er det
3,
11 elever per datamaskin når vi tar med alle
4137 grunnskoler (
1.-
10.trinn)
". For de
56 Linux-skolene jeg har klart å
4138 koble mot informasjon i GSI er det
2,
28 elever per elevdatamaskin,
4139 hvilket betyr at det er
36% høyere PC-tetthet på Linux-skoler enn
4140 landsgjennomsnittet. Linux-skolen med høyest tettet blant de jeg har
4141 notert -skole er Flora ungdomsskule i Flora kommune med
0.82 elev
4142 pr. PC (
482 elever,
588 elevdatamaskiner).
</p
>
4144 <p
>Skolelinux gir datamaskiner lengre levetid, og en kan dermed få
4145 flere operative datamaskiner for samme budsjett, i tillegg til en
4146 rekke andre fordeler. Kan det være forklaringen på forskjellen?
</p
>
4148 <p
>Tallene må tas med en liten klype, da GSI ser ut til å ha endel
4149 feilføringer. Jeg synes i hvert fall en skole med
423 elever og
9
4150 elevmaskiner ser mistenkelig ut. Eller en skole med
346 elever,
0
4151 elevmaskiner, som er et annet ekstremt eksempel jeg fant.

4171 <p
>I teach ICT part time at the Rudolf Steiner School in Kings
4172 Langley, near London, UK. Previously I worked as a technical
4173 author/trainer while my children attended the school, and I also
4174 contributed to the Schoolforge UK community with the aim of
4175 encouraging UK schools to adopt free/open source software. Five or six
4176 years ago we had about
50 schools interested in some way, but we
4177 weren
't able to convert many of them into sustainable
4178 installations.
</p
>
4180 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4181 project?
</strong
></p
>
4183 <p
>Skolelinux had two representatives at an early Edubuntu meeting in
4184 London which I attended. However at that time our school network had
4185 just been installed using CentOS, LTSP
4 and GNOME. When LTSP
5 came
4186 along we switched to Edubuntu thin client servers so now we have a
4187 mixed environment which includes Windows PCs and student laptops, as
4188 well as their MacBooks and iPads. However, the proprietary systems
4189 have always been rather problematic, and we never built a GUI for the
4190 LDAP server, so when I discovered Skolelinux is configured for all
4191 these things we decided to try it.
</p

4193 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4194 Edu?
</strong
></p
>
4196 <p
>By far the biggest advantage is the Debian Edu community. Apart
4197 from that I have always believed in the same
"sustainable computing
"
4198 goals that Skolelinux is built on: installing Linux on computers which
4199 would otherwise be thrown away, to provide a reliable, secure and
4200 low-cost IT environment for schools. From my own experience I know
4201 that a part-time person can teach and manage a network of about
25
4202 Linux computers, but it would take much more of my time if we had
4203 proprietary software everywhere.

4208 <p
>As a newcomer I
'm just finding out who
's who in the community and
4209 how you
're organised, and what your procedures are for dealing with
4210 various things such as editing manual pages and so-on. The only
4211 English language mailing list seems to be for developers as well as
4212 users, so my inbox needs heavy pruning each day!

4216 <p
>Besides the software already mentioned at school we use Samba,
4217 OpenLDAP, CUPS, Nagios and Dansguardian for the network, and on the
4218 desktops we have LibreOffice, Firefox, GIMP and Inkscape. At home I
4219 use Ubuntu and an Android
4 eePad Transformer (but I
'm not sure if
4220 that counts...)
</p

4222 <p
><strong
>Which strategy do you believe is the right one to use to
4223 get schools to use free software?
</strong
></p
>
4225 <p
>That
's a tough question! For very many years UK schools installed
4226 and taught only proprietary software, so that at the highest levels
4227 the notion of
"computer
" means simply
"proprietary office
4228 applications
". However, schools today are experiencing budget
4229 constraints, and many are having to think hard about upgrading Windows
4230 XP. At the same time, we have students showing teachers how to use
4231 iPads, MacBooks and Android, so the choice of operating system is no
4232 longer quite so automatic. What is more, our government at last
4233 realised that we need people with programming skills, so they
're
4234 putting coding back in the curriculum! And it
's encouraging that the
4235 first
10,
000 Raspberry Pi units sold out in
2 hours.
</p
>
4237 <p
>I don
't really know what strategy is going to get UK schools to use
4238 free software, but building an active community of Skolelinux/Debian
4239 Edu users in this country has to be part of it.

4249 it is important to make it both easy to contribute and to keep the

4251 believe is a very efficient work flow.
</p

4255 <li
>The documentation is written in a
4256 <a href=

</a

4257 <a href=

4259 docbook XML.
</li
>
4261 <li
>This docbook document is given to po4a to extract a gettext style
4262 .pot file with the content, which in turn is used to create .po files
4263 with the translated text.
</li
>
4265 <li
>The .po files are given to translators, and they can always tell
4266 which part of the original wiki document is new or changed. They can
4267 use their normal translation tools like lokalize or poedit to write
4268 the translation. There is even a system in place to handle translated
4271 <li
>The translated .po files are combined with the original docbook
4272 XML document using po4a to create a translated docbook document.
</li
>
4274 <li
>The final step is to use all the generated docbook files and
4275 create PDF and HTML version of the original and translated documents.
</li
>
4279 <p
>This setup work very well, but have a few issues. The biggest
4280 issue is that
<a href=
"http://moinmo.in/DocBook
">the docbook support
4281 we use in moinmoin
</a
> is not actively maintained. The docbook
4282 support is also buggy, and our build system contain workarounds to
4283 make sure the generated docbook is usable despite these bugs.

4343 har også en datter som går på en friskole, som også bruker Skolelinux.
4344 Som kjent har ikke friskoler de samme økonomiske rammebetingelsene som
4345 offentlige skoler, så for dem var det det absolutt beste alternativet.
4346 De anser også Skolelinux som et stabilt system, som bare går og går (i
4347 motsetning til det lille Windows-baserte nettverket de har på
4348 admin-siden).

4352 <p

4353 lydløse og raskere arbeidsstasjoner som er bedre i klasserommet.
4354 Lengre levetid på PC

4355 så klart fjerning av alle lisenskostnader. Personlig synes jeg også at
4356 mange av programmene er bedre enn alternativene. Men dette er ofte en
4357 smakssak og avhengig om man må ha det man er vant til fra før.

4362 kompatibilitet med arbeidsstasjoners/bærbare maskiner sine
4363 nettverksdrivere eller skjermkort. Men dette løser vi i skolene ved
4364 standardisering. Ellers er det få, om nesten ingen, av de kjente
4365 maskinvare / infrastruktur leverandørene til fylkes- / kommuner som
4366 tilbyr denne plattformen. Skal dette endre seg så må kommunene selv

>Fortsette å presentere flere av de gode eksemplene hvor Debian Edu
4380 / Skolelinux brukes i kommuner og enkeltskoler. Vi må få bedre frem
4381 at det er mulig tilknytte både Windows og Mac klienter på denne
4382 plattformen (selv om det vil øke driftskostnadene). Dette gjøres
4383 mange steder. Spesielt er det mange lærere som ønsker å bruke
4384 Windows/Mac-bærbare, gjerne som sin private PC også. Det er også mulig
4385 for kommunen å integrere med Active Directory i stedet for OpenLDAP
4386 som kommer med ut av boksen (selv om også dette øker kostnadene).
4387 Dette vil muligens bidra til å fjerne noe motstand hos noen
4388 potensielle brukere / driftpersonell for å ta i bruk noe
4389 nytt. Fremveksten av mobile brukere og nettbrett går i vår favør.
4390 Brukerne blir kjent og vant til flere nye operativsystemer /
4391 brukergrensesnitt. Så utviklerfellesskapet bør jobbe videre med å
4392 integrere flere nye klienttyper, som ultra lav-kostklienter og
4393 nettbrett (blant annet fri programvare-alternativet

>Inspired by
<a href=
"http://raphaelhertzog.com/tag/interview/
">the
4425 interview series
</a
> conducted by Raphael, I started a Norwegian
4426 interview series with people involved in the Debian Edu / Skolelinux
4427 community. This was so popular that I believe it is time to move to a
4428 more international audience.
</p
>
4430 <p
>While
<a href=
"http://www.skolelinux.org/
">Debian Edu and
4431 Skolelinux
</a
> originated in France and Norway, and have most users in
4432 Europe, there are users all around the globe. One of those far away
4433 from me is Nigel Barker, a long time Debian Edu system administrator
4434 and contributor. It is thanks to him that Debian Edu is adjusted to
4435 work out of the box in Japan. I got him to answer a few questions,
4436 and am happy to share the response with you. :)
4439 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
4441 <p
>My name is Nigel Barker, and I am British. I am married to Yumiko,
4442 and we have three lovely children, aged
15,
14 and
4(!) I am the IT
4443 Coordinator at Hiroshima International School, Japan. I am also a
4444 teacher, and in fact I spend most of my day teaching Mathematics,
4445 Science, IT, and Chemistry. I was originally a Chemistry teacher, but
4446 I have always had an interest in computers. Another teacher teaches
4447 primary school IT, but apart from that I am the only computer person,
4448 so that means I am the network manager, technician and webmaster,
4449 also, and I help people with their computer problems. I teach python
4450 to beginners in an after-school club. I am way too busy, so I really
4451 appreciate the simplicity of Skolelinux.
</p
>
4453 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4454 project?
</strong
></p
>
4456 <p
>In around
2004 or
5 I discovered the ltsp project, and set up a
4457 server in the IT lab. I wanted some way to connect it to our central
4458 samba server, which I was also quite poor at configuring. I discovered
4459 Edubuntu when it came out, but it didn
't really improve my setup. I
4460 did various desperate searches for things like
"school Linux server
"
4461 and ended up in a document called
"Drift
" something or other. Reading
4462 there it became clear that Skolelinux was going to solve all my
4463 problems in one go. I was very excited, but apprehensive, because my
4464 previous attempts to install Debian had ended in failure (I used
4465 Mandrake for everything - ltsp, samba, apache, mail, ns...). I
4466 downloaded a beta version, had some problems, so subscribed to the
4467 Debian Edu list for help. I have remained subscribed ever since, and
4468 my school has run a Skolelinux network since Sarge.
</p
>
4470 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4471 Edu?
</strong
></p
>
4473 <p
>For me the integrated setup. This is not just the server, or the
4474 workstation, or the ltsp. Its all of them, and its all configured
4475 ready to go. I read somewhere in the early documentation that it is
4476 designed to be setup and managed by the Maths or Science teacher, who
4477 doesn
't necessarily know much about computers, in a small Norwegian
4478 school. That describes me perfectly if you replace Norway with
4481 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
4482 Edu?
</strong
></p
>
4484 <p
>The desktop is fairly plain. If you compare it with Edubuntu, who
4485 have fun themes for children, or with distributions such as Mint, who
4486 make the desktop beautiful. They create a good impression on people
4487 who don
't need to understand how to use any of it, but who might be
4488 important to the school. School administrators or directors, for
4489 instance, or parents. Even kids. Debian itself usually has ugly
4490 default theme settings. It was my dream a few years back that some
4491 kind of integration would allow Edubuntu to do the desktop stuff and
4492 Debian Edu the servers, but now I realise how impossible that is. A
4493 second disadvantage is that if something goes wrong, or you need to
4494 customise something, then suddenly the level of expertise required
4495 multiplies. For example, backup wasn
't working properly in Lenny. It
4496 took me ages to learn how to set up my own server to do rsync backups.
4497 I am afraid of anything to do with ldap, but perhaps Gosa will
4500 <p
><strong
>Which free software do you use daily?
</strong
></p
>
4502 <p
>Nowadays I only use Debian on my personal computers. I have one for
4503 studio work (I play guitar and write songs), running AV Linux
4504 (customised Debian) a netbook running Squeeze, and a bigger laptop
4505 still running Skolelinux Lenny workstation. I have a Tjener in my
4506 house, that
's very useful for the family photos and music. At school
4507 the students only use Skolelinux. (Some teachers and the office still
4508 have windows). So that means we only use free software all day every
4509 day. Open office, The GIMP, Firefox/Iceweasel, VLC and Audacity are
4510 installed on every computer in school, irrespective of OS. We also
4511 have Koha on Debian for the library, and Apache, Moodle, b2evolution
4512 and Etomite on Debian for the www. The firewall is Untangle.
</p
>
4514 <p
><strong
>Which strategy do you believe is the right one to use to
4515 get schools to use free software?
</strong
></p
>
4517 <p
>Current trends are in our favour. Open source is big in industry,
4518 and ordinary people have heard of it. The spread of Android and the
4519 popularity of Apple have helped to weaken the impression that you have
4520 to have Microsoft on everything. People complain to me much less about
4521 file formats and Word than they did
5 years ago. The Edu aspect is
4522 also a selling point. This is all customised for schools. Where is the
4523 Windows-edu, or the Mac-edu? But of course the main attraction is
4524 budget.The trick is to convince people that the quality is not
4525 compromised when you stop paying and use free software instead. That
4526 is one reason why I say the desktop experience is a weakness. People
4527 are not impressed when their USB drive doesn
't work, or their browser
4528 doesn
't play flash, for example.

>Many years ago, the
<a href=
"http://www.skolelinux.org/
">Skolelinux
4575 / Debian Edu project
</a
> initiated a student project to create a tool
4576 for making stop motion movies. The proposal came from a teacher
4577 needing such tool on Skolelinux. The project, called
"stopmotion
",
4578 was manned by two extraordinary students and won a school award and a
4579 national aware with this great project. The project was initiated and
4580 mentored by Herman Robak, and manned by the students Bjørn Erik Nilsen
4581 and Fredrik Berg Kjølstad. They got in touch with people at Aardman
4582 Animation studio and received feedback on how professionals would like
4583 such stopmotion tool to work, and the end result was and is used by
4584 animators around the globe. But as is usual after studying, both got
4585 jobs and went elsewhere, and did not have time to properly tend to the
4586 project, and it has been lingering for a few years now. Until last
4589 <p
>Last year some of the users got together with Herman, and moved the
4590 project to Sourceforge and in effect restarted the project under a new
4592 <a href=
"http://sourceforge.net/projects/linuxstopmotion/
">linuxstopmotion
</a
>.
4593 The name change was done to make it possible to find the project using
4594 Internet search engines (try to search for
'stopmotion
' to see what I
4595 mean). I
've been following
4596 <a href=
"https://lists.sourceforge.net/lists/listinfo/linuxstopmotion-community

2001. Skolene slet
4687 med både utstyr og Internett-tilgang. De klarte ikke å møte
4688 forventningene til data i skolen. Driften av PC-ene var uholdbar. Som
4689 regel hadde rektor pekt ut en ivrig lærer til å passe på PC-ene,
4690 gjerne naturfaglæreren. Mange lærere jobbet mye ubetalt overtid for å

40 datamaskiner på hver sin skole. Med
300 elever og
4692 lærere som brukere, blir det fort mye mer arbeid enn de
4-
8 timene de
4693 kunne bruke på PC-drift. Skolene hadde kun en femtedel av
4694 IT-budsjettet som ble brukt på PC-ene i rådhuset.
</p
>
4696 <p
>Vi erfarte at skolene hadde mye datautstyr som stod ubrukt. Skolene
4697 manglet penger til Microsoft-lisenser. Selv med solide skolerabatter,
4698 kostet Microsoft-lisensene gjerne like mye som PC-ene i seg selv over
4699 en periode på
5-
6 år.
</p
>
4701 <p
>Viktigheten av språklig mangfold og pedagogiske programmer var også
4702 viktig for oss. Vi oversatte mange skoleaktuelle programmer til
4703 nynorsk, nordsamisk og bokmål. Dette lenge før andre tok denne
4704 oppgaven seriøst. Allerede etter ett år hadde vi etablert et helt
4705 arsenal av skoleaktuelle programmer på nynorsk, bokmål og
4706 nordsamisk. Vi spredde vår ide om språklig mangfold til de andre frie
4707 prosjekter internasjonalt. Resultatene ser vi i mange land. Det er de
4708 frie programmene som kommer på brukernes morsmål. Det er en av flere
4709 gode grunner til at fri programvare som LibreOffice, VLC, KDE og
4710 Firefox konkurrerer ut godseid programvare mange steder i verden.

4712 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
4714 <p
>Fordelene er at Skolelinux tilbyr over
100 skoleaktuelle programmer
4715 på de norske språkene, uten ett øre i lisenskostnader. Systemet gir
4716 enormt lave driftskostnader med diskløse arbeidsstasjoner og bærbare
4717 med roaming. Skolelinux krever også mindre av maskinvaren.
</p
>
4719 <p
>Man kan fint kjøre systemet med
512 MB RAM på en bærbar PC sammen
4720 med en nettvideo i nettleseren og en presentasjon med
4721 LibreOffice. Konkurrerende system krever fort
2 GB RAM for å få til
4722 noe tilsvarende uten at det går ufattelig tregt. Skal man gjøre noe
4723 nyttig, krever konkurrentene til Linux mye større harddisk. Skoler har
4724 rapportert at de fort har fått
50% flere nye maskiner om de velger
4725 Linux. Dette i tillegg til de årlige besparelsene ved å unngå
4726 lisensbetaling til godseid programvare.
</p
>
4728 <p
>De lave driftskostnadene gjør at delstater i Europa har titusener
4729 av datamaskiner med Skolelinux i skolen. F.eks. er det under ti
4730 personer som drifter
70.000 PC-systemer i skolene i Extremadura i
4731 Spania. Det er slett ikke uvanlig at norske kommuner har
1500-
2000
4732 datamaskiner med Skolelinux. Driften tar ett årsverk. Slår flere
4733 kommuner seg sammen, kan de få samme sentraliserte stordriftsfordeler
4734 som delstater i Tyskland og Spania. Delstater som kjører Skolelinux
4735 på alle skolene. Bare noen få personer sentraldrifter titusenvis av

>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
4740 <p
>Den største ulempen for Skolelinux er motstand mot Linux fra
4741 IT-sjefer i det offentlige. Dette er ledere som holder innlegg som
4742 snytt ut av evangelist-håndboka til Microsoft. Dette gjøres i ett
4743 arbeidsmarked med stor vekst i etterspørselen etter Linux-fagfolk i
4744 privat sektor. Etterspørselen har økt mer enn noe annet tekniske yrke
4745 siste tiåret. Åtte av ti ledere vil ansette Linux-fagfolk i
2012,
4746 rapporterer jobbnettstedet Dice.com på oppdrag av Linux
4747 Foundation.
</p
>
4749 <p
>Det mangler
16.000 ingeniører og IKT-fagfolk i Norge rapporterte
4750 arbeids- og velferdsetaten NAV. Linux-fagfolk kan velge svært
4751 interessante jobber med alt fra apps på ledende mobilsystem laget med
4752 Linux, sky- tjenester eller web-applikasjoner. De raskest voksende
4753 teknologiselskapene i verden er ute etter Linux-fagfolk. Det være seg
4754 Amazon, Google, Facebook og IBM for å nevne noen. Linux er kritisk
4755 for å sikre veksten i markedet. Det sier seg selv at lønningene og
4756 jobbmulighetene er bedre enn for andre tekniske yrker.
</p
>
4758 <p
>Skal man lage apps for mobilen, smart-TV-en eller
4759 underholdningssystemet i bilen eller på flyet, er det Linux som
4760 gjelder. Med en slik konkurranse om Linux-kompetansen, kombinert med
4761 motstanden mot Linux hos mange IT-sjefer i offentlig sektor, så
4762 hindrer kommunene rekruttering av flere Linux- fagfolk. Skolene blir
4763 tvunget til å velge dyrere og mindre komplette IT-system. De har
4764 blitt hengende igjen slik IT var på begynnelsen av
2000- tallet. Dette
4765 fordi IT-ledere ikke har tilpasset seg markedet det siste tiåret.
</p
>
4767 <p
>Når det er sagt, er Skolelinux svært enkelt å lære seg også for de
4768 som ikke kan. Det viser alle lærerne som drifter systemet for
4769 hundrevis og tusenvis av systemer. Det meste er på plass rett ut av
4770 boksen. I tillegg er det solid med dokumentasjon med god hjelp på
4771 nettet. Det er mange kommuner som har ansatt en lærer som først lærte
4772 Skolelinux på sin skole, for så å drifte alle PC-ene i kommunen med
4773 Skolelinux. Det kan fort være snakk om
1000-
3000 datamaskiner på
10-
15
4774 skoler som sentraldriftes med en stilling. Står man ordentlig fast,
4775 kan man også kjøpe profesjonell hjelp fra selskap som støtter
4776 Skolelinux. Det er flere slike selskap i Norge og i utlandet.

30.000 Linux-programmer. Det
4783 finnes ikke tid i livet å undersøke alle valgmulighetene. Derfor er
4784 det bra med Skolelinux i skolen, da utvalget av programmer er
4785 begrenset til hva som er aktuelt i skolefagene.

4792 enkeltskoler eller hele kommuner. Pakken må inneholde tjenermaskiner,
4793 svært rimelige diskløse arbeidsstasjoner, nettbrett med Plasma Active,
4794 og bærbare med roaming. Alt er godt testet med Debian. I et slikt
4795 anbud er det mulig å legge til sentraliserte drifts- og

4840 stiftelsen Åpne kontorprogram på norsk for å oversette og teste den
4841 norske utgaven av OpenOffice.org. Arbeidet har hele tiden vært

>Skolelinux handler i likhet med utdanningssektoren om å dele
4849 kunnskap med andre, og det er dette som er hovedstyrken til
4850 prosjektet. Selv om Skolelinux hovedsaklig er involvert i utvikling
4851 av programvare, er det også et sted der man kan utfolde seg uavhengig
4852 av bakgrunn og ferdigheter.

4876 også utvikle vår egen tilpasset det norske markedet. Det er også
4877 mulig å involvere utdanningssektoren direkte i arbeidet, for eksempel
4878 gjennom studentprosjekter der elevene selv er med å utforme
4879 programvare direkte eller indirekte gjennom aktive bidrag. Dette gjør
4880 ikke bare samarbeidet tettere, men fokuset på standarder og friheten
4881 til å velge sin egen løsning vil kanskje stimulere interessen for
4882 framtidig deltakelse i bransjen. Vi som driver med fri og åpen
4883 programvare ønsker oss ikke rene konsumenter, men tenkende og
4884 selvstendige individer som kan være med å skape sin egen fremtid.

>New in the Squeeze version of
4894 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> is the
4895 ability for clients to automatically configure their proxy settings
4896 based on their environment. We want all systems on the client to use
4897 the WPAD based proxy definition fetched from
<tt
>http://wpad/wpad.dat
</tt
>, to
4898 allow sites to control the proxy setting from a central place and make
4899 sure clients do not have hard coded proxy settings. The schools can
4900 change the global proxy setting by editing
4901 <tt
>tjener:/etc/debian-edu/www/wpad.dat
</tt
> and the change propagate
4902 to all Debian Edu clients in the network.
</p
>
4904 <p
>The problem is that some systems do not understand the WPAD system.
4905 In other words, how do one get from a WPAD file like this (this is a
4906 simple one, they can run arbitrary code):

4923 http_proxy=http://webcache:
3128/
4924 ftp_proxy=http://webcache:
3128/
4925 </pre
></blockquote
>
4927 <p
>To do this conversion I developed a perl script that will execute
4928 the javascript fragment in the WPAD file and return the proxy that
4930 <tt
><a href=
"http://www.debian.org/
">http://www.debian.org/
</a
></tt
>,
4931 and insert this extracted proxy URL in
<tt
>/etc/environment
</tt
> and
4932 <tt
>/etc/apt/apt.conf
</tt
>. The perl script wpad-extract work just
4933 fine in Squeeze, but in Wheezy the library it need to run the
4934 javascript code is
<a href=
"http://bugs.debian.org/
631045">no longer
4935 able to build
</a
> because the C library it depended on is now a C++
4936 library. I hope someone find a solution to that problem before Wheezy
4937 is frozen. An alternative would be for us to rewrite wpad-extract to
4938 use some other javascript library currently working in Wheezy, but no
4939 known alternative is known at the moment.
</p
>
4941 <p
>This automatic proxy system allow the roaming workstation (aka
4942 laptop) setup in Debian Edu/Squeeze to use the proxy when the laptop
4943 is connected to the backbone network in a Debian Edu setup, and to
4944 automatically use any proxy present and announced using the WPAD
4945 feature when it is connected to other networks. And if no proxy is
4946 announced, direct connections will be used instead.
</p
>
4948 <p
>Silently using a proxy announced on the network might be a privacy
4949 or security problem. But those controlling DHCP and DNS on a network
4950 could just as easily set up a transparent proxy, and force all HTTP
4951 and FTP connections to use a proxy anyway, so I consider that
4952 distinction to be academic. If you are afraid of using the wrong
4953 proxy, you should avoid connecting to the network in question in the
4954 first place. In Debian Edu, the proxy setup is updated using dhcp and
4955 ifupdown hooks, to make sure the configuration is updated every time
4956 the network setup changes.
</p
>
4958 <p
>The WPAD system is documented in a

5010 var noen annen løsning. «Vandrende arbeidsstasjon» mener jeg ikke
5011 fantes da. Dessuten ville jeg ha siste versjon, da den KDE-versjonen

5066 package, the BIOS is told to turn the machine back on around
07:
00 +-
5067 10 minutes. If this isn
't working, one can configure wake-on-lan to
5068 try to turn on the client. The wake-on-lan option is only documented
5069 and not enabled by default in Debian Edu.
</p
>
5071 <p
>It is important to not turn all machines on at once, as this can
5072 blow a fuse if several computers are connected to the same fuse like
5073 the common setup for a classroom. The nvram-wakeup method only work
5074 for machines with a functioning hardware/BIOS clock. I
've seen old
5075 machines where the BIOS battery were dead and the hardware clock were
5076 starting from
0 (or was it
1990?) every boot. If you have one of
5077 those, you have to turn on the computer manually.
</p
>
5079 <p
>The shutdown-at-night package is completely self contained, and can
5080 also be used outside the Debian Edu environment. For those without a
5081 central LDAP server with netgroups, one can instead touch the file
5082 <tt
>/etc/shutdown-at-night/shutdown-at-night
</tt
> to enable it.
5083 Perhaps you too can use it to save some power?

>I am happy to announce that finally we managed today to wrap up and
5093 publish the third beta version of
5094 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> based
5095 on Squeeze. If you want to test a LDAP backed Kerberos server with
5096 out of the box PXE configuration for running diskless machines and
5097 installing new machines, check it out. If you need a software
5098 solution for your school, check it out too. The full announcement is
5099 <a href=
"http://lists.debian.org/debian-edu-announce/

">available
</a

5100 on the project announcement list.
</p
>
5102 <p
>I am very happy to report these changes and improvements since
5103 beta2 (there are more, see announcement for full list):
</p
>
5107 <li
>It is now possible to change the pre-configured IP subnet from
5108 10.0.0.0/
8 to something else by using the subnet-change tool after
5109 the installation.
</li
>
5111 <li
>Too full partitions are now automatically extended on the Main
5112 Server, based on the rules specified in /etc/fsautoresizetab.
</li
>
5114 <li
>The CUPS queues are now automatically flushed every night, and all
5115 disabled queues are restarted every hour. This should cut down on
5116 the amount of manual administration needed for printers.
</li
>
5118 <li
>The set of initial users have been changed. Now a personal user
5119 for the local system administrator is created during installation
5120 instead of the previously created localadmin and super-admin users,
5121 and this user is granted administrative privileges using group
5122 membership. This reduces the number of passwords one need to keep
5123 up to date on the system.
</li
>
5127 <p
>The new main server seem to work so well that I am testing it as my
5128 private DNS/LDAP/Kerberos/PXE/LTSP server at home. I will use it look
5129 for issues we could fix to polish Debian Edu even further before the
5130 final Squeeze release is published.
</p
>
5132 <p
>Next weekend the project organise a
5133 <a href=
"http://lists.debian.org/debian-edu-announce/
2012/
01/msg00001.html
">developer
5134 gathering
</a

5135 version, and start initial planning for the Wheezy version. Perhaps I
5136 will see you there?

5145 <description><p
>With some computer hardware, one need non-free firmware blobs.
5146 This is the sad fact of todays computers. In the next version of
5147 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> based
5148 on Squeeze, we provide several scripts and modifications to make
5149 firmware blobs easier to handle. The common use case I run into is a
5150 laptop with a wireless network card requiring non-free firmware to
5151 work, but there are other use cases as well.
</p
>
5153 <p
>First and foremost, Debian Edu provide ISO images for DVD and CD
5154 with all firmware packages in the Debian sections main and non-free
5155 included, to ensure debian-installer find and can install all of them
5156 during installation. This take care firmware for network devices used
5157 by the installer when installing from from local media. But for
5158 example multimedia devices are not activated in the installer and are
5159 not taken care of by this.
</p
>
5161 <p
>For non-network devices, we provide the script
5162 <tt
>/usr/share/debian-edu-config/tools/auto-addfirmware
</tt
> which
5163 search through the
<tt
>dmesg
</tt
> output for drivers requesting extra
5164 firmware. The firmware file name is looked up in the Contents-ARCH.gz
5165 file available in the package repository, and the packages providing
5166 the requested firmware file(s) is installed. I have proposed to do
5167 something similar in debian-installer (BTS report
5168 <a href=
"http://bugs.debian.org/
655507">#
655507</a
>), to allow PXE
5169 installs of Debian to handle firmware installation better. Run the
5170 script as root from the command line to fetch and install the needed
5171 firmware packages.
</p
>
5173 <p
>Debian Edu provide PXE installation of Debian out of the box, and
5174 because some machines need firmware to get their network cards
5175 working, the installation initrd some times need extra firmware
5176 included to be able to install at all. To fill the PXE installation
5177 initrd with extra firmware, the
5178 <tt
>/usr/share/debian-edu-config/tools/pxe-addfirmware
</tt
> script is
5179 provided. Again, just run it as root on the command line to fill the
5180 PXE initrd with firmware packages.
</p
>
5182 <p
>Last, some LTSP clients might also need firmware to get their
5183 network cards working. For this,
5184 <tt
>/usr/share/debian-edu-config/tools/ltsp-addfirmware
</tt
> is
5185 provided to update the LTSP initrd with firmware blobs. It is used
5186 the same way as the other firmware related tools.
</p
>
5188 <p
>At the moment, we do not run any of these during installation. We
5189 do not know if this is acceptable for the local administrator to use
5190 non-free software, and it is their choice.

5209 språket melde seg til dyst. Det er mangel på nordsamiske oversettere

>The next version of
<a href=
"http://www.skolelinux.org/
">Debian Edu
5249 / Skolelinux
</a
> will include a new tool
5250 <tt
>sitesummary2ldapdhcp
</tt
>, which can be used to quickly set up all
5251 the computers in a school without much manual labour. Here is a short
5252 summary on how to use it to set up a new school.
</p
>
5254 <p
>First, install a combined Main Server and Thin Client Server as the
5255 central server in the network. Next, PXE boot all the client machines
5256 as thin clients and wait
5 minutes after the last client booted to
5257 allow the clients to report their existence to the central server. When
5258 this is done, log on to the central server and run
5259 <tt
>sitesummary2ldapdhcp -a
</tt
> in the
<tt
>konsole
</tt
> to use the
5260 collected information to generate system objects in LDAP. The output
5261 will look similar to this:
</p
>
5263 <p
><blockquote
><pre
>
5264 % sitesummary2ldapdhcp -a
5265 info: Updating machine tjener.intern [

5271 enter password: *******
5273 </pre
></blockquote
></p
>
5275 <p
>After providing the LDAP administrative password (the same as the
5276 root password set during installation), the LDAP database will be
5277 populated with system objects for each PXE booted machine with
5278 automatically generated names. The final step to set up the school is
5279 then to log into
<a href=
"https://oss.gonicus.de/labs/gosa/
">GOsa
</a
>,
5280 the web based user, group and system administration system to change
5281 system names, add systems to the correct host groups and finally
5282 enable DHCP and DNS for the systems. All clients that should be used
5283 as diskless workstations should be added to the workstation-hosts
5284 group. After this is done, all computers can be booted again via PXE
5285 and get their assigned names and group based configuration
5286 automatically.
</p
>
5288 <p
>We plan to release beta3 with the updated version of this feature
5289 enabled this weekend. You might want to give it a try.
</p

5291 <p
>Update
2012-
01-
28: When calling sitesummary2ldapdhcp to add new
5292 hosts, one need to add the option -a. I forgot to mention this in my
5293 original text, and have added it to the text now.

5324 <p
>Kommunen satset på Skolelinux i
2004. Jeg var ikke med i
5325 beslutningsprosessen den gang, men ble likevel med fra starten når
5326 dette ble levert.

5328 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
5330 <p
>Fordelene med Skolelinux er rask oppstart, sentral drift av
5331 klientene, klienter som jobber raskt og effektivt, bedre
5332 funksjonalitet på eldre utstyr og en ganske god programpakke med fri
5333 programvare som følger med. Løsningen med halvtykke klienter gjør at
5334 prosessering skjer lokalt med alltid ferske maskiner.
</p
>
5336 <p
>Skolelinux kan fungere godt på gammelt utstyr, men det er klart at
5337 utstyr også blir for gammelt selv for Skolelinux. I forbindelese med
5338 at vi nylig fikk nye servere og ny installasjon kastet jeg ut ca
60
5339 klienter som fortsatt var i drift etter at de var kjøpt godt brukt i
5340 2004. Noe var rundt
15 år gammelt, men var fortsatt i bruk. Noen
5341 klaget på at det nå gikk veldig tregt på en del pedagogiske nettsider
5342 med flash o.l. Det er fullt forståelig.
</p
>
5344 <p
>Jeg fikk nylig et spørsmål fra ungdomsskolens rektor om jeg kunne
5345 legge inn
<a href=
"http://freemind.sourceforge.net/
">FreeMind
</a
>, et
5346 tankekartprogram , på skolens elev-Windowsmaskiner. Lærerne hadde
5347 vært på kurs og ville ta dette i bruk. Skolen har ca halvparten av
5348 elevmaskinene på bærbare Windowsmaskiner. Da kunne jeg fortelle at
5349 dette programmet allerede lå inne på den nye Skolelinuxløsningen
5350 som nettopp var satt i drift, klart til bruk.
</p
>
5352 <p
>Vi har de bærbare maskinene på ungdomsskolen i domene med
5353 Skolelinux. Dette fungerer også meget bra nå. Elevene får opp en
5354 midlertidig windowsprofil når de logger på. Denne profilen slettes
5355 etter at de logger av, noe som medfører rene profiler hver gang de
5356 starter opp en maskin. De må lagre i sin Skolelinprofil, noe som
5357 medfører at de får tak i sine filer uavhengig av om de starter en
5358 Windowsmaskin eller en Skolelinuxklient. Det er mye mindre trafikk i
5359 det trådløse nettet etter at ikke hele profiler blir lastet opp til de
5360 enkelte Windowsmaskinene og tilbake når man avslutter. Jeg vet ikke om
5361 dette er standardoppsett i Skolelinux, men slik er vårt oppsett
5364 <p
>Vi har i flere år satt opp vår løsning slik at skriverkøer slettes
5365 og skrivere startes hver natt. Hyggelig å høre at dette nå skal bli
5366 en standard i Skolelinuxløsningen. Dette har vært en god hjelp for
5369 <p
>Elevene er lite opptatt av om de jobber på en Skolelinux eller en
5370 Windowsmaskin bare de har de programmene de trenger og at det virker
5371 når det skal brukes. Vi kjører mest mulig de samme programmene på
5372 Windows som i Skolelinux, som f.eks Audacity og LibreOffice.
</p
>
5374 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
5376 <p
>Lærere bruker hos oss Windows. Dette fordi de da selv har mer
5377 kontroll over sin maskin, kan bruke den overalt, og kan legge inn
5378 programmer selv når de trenger noe i forhold til kurs o.l de er
5379 på. Jeg tror lærernes selvstendighet her gjør dem tryggere på IKT-bruk
5380 generelt. Det at de av og til får opp advarsler og lignende gjør også
5381 at de må tenke igjennom og spørre om ting rundt datasikkerhet.
</p
>
5383 <p
>Det er en del programmer vi bruker som ikke finnes for Linux. Mest
5384 brukt er nok Photostory3 som brukes i mange sammenhenger, særlig på
5385 ungdomsskolen, bl.a. til å lage herbarier (plantesamling) . Dette
5386 finnes gratis for Windows, men er ikke fri programvare. Vi er opptatt
5387 av at programmer elevene bruker på skolen også kan brukes gratis
5388 hjemme. Det er også en del programmer som brukes til spesielle elever
5389 som bare går i Windows. Det er viktig med fokus på funksjoner og ikke
5390 på hvilket OS man bruker.
</p

5392 <p
>For oss er det kombinasjonen mellom Skolelinux og Windows som gir
5393 oss en god og hel løsning. Skolelinux er best der de er gode.

5397 <p
>Selv er det LibreOffice jeg bruker til daglig. Jeg bruker selv en
5398 Windowsmaskin. Jeg har benyttet en del fri programvare i forbindelse
5399 med sjekking av trafikk i nettverk, slik som Wireshark, men dette er
5400 jo ikke aktuelt for skolene. Jeg er generelt glad i programmer som
5401 fungerer på både Linux og Windows og gjerne MAC.

5406 <p
>Det er viktig at det benyttes programmer som elevene også kan ta i
5407 bruk hjemme. Det skal da være enkelt, lovlig og gratis for
5408 elevene. Da er jeg ikke lenger veldig opptatt av om det kalles
"fri
5409 programvare
". For skolene tror jeg
"gratis
" og
"funksjonelt
" er bedre
5410 begreper enn
"fri
" i forhold til programmer. De fleste skiller nok
5411 ikke mellom
"fri
" og
"gratis
". Det er nå svært mange elever som
5412 benytter OpenOffice eller LibreOffice som sin primære kontorpakke

5469 <a href=

5470 for release. The initial problem I looked at was particularly
5471 interesting.
</p

5473 <P
>The installer would hang at the end when it was doing it
5474 post-installation configuration, and whatevery I did to try to find
5475 the cause and fix it always worked while I tested it, but never when I
5476 integrated it into the installer and ran the installation from
5477 scratch. I would try to restart processes, close file descriptors,
5478 remove or create files, and the installer would always unblock and
5479 wrap up its tasks.
</p
>
5481 <p
>Eventually the cause was found. The kernel was simply running out
5482 of entropy, causing the Kerberos setup to hang waiting for more.
5483 Pressing keys was adding entropy to the kernel, and thus all my tries
5484 to fix the problem worked not because what I was typing to fix it, but
5485 because I was typing.
</P
>
5487 <p
>The fix I implemented was to add a background process looking at
5488 the level of entropy in the kernel (by checking
5489 /proc/sys/kernel/random/entropy_avail), and if it was too small, the
5490 installer will flush the kernel file buffers and do
'find /
' to
5491 generate some disk IO. Disk IO generate entropy in the kernel, and is
5492 one of the few things that can be initated from within the system to
5493 generate entropy.

5512 Denne gangen har jeg besøk av et avtroppende styremedlem i

5518 <p
>Jeg heter Peter Hansteen, og jobber til daglig som seniorkonsulent
5519 i EDB ErgoGroup i Bergen. I praksis betyr det systemadministrasjon på
5520 Unix (primært Solaris, men en viss komponent av Linux). Men Solaris
5521 er for meg et relativt nytt bekjentskap, hovedplattformen min har
5522 generelt vært OpenBSD og til dels FreeBSD.

5526 <p
>Jeg husker ikke helt alle detaljene mer ;) - men jeg tror det var
5527 gjennom news-gruppen no.it.os.unix.linux.diverse, efn-listen og
5528 etterhvert også BLUG-miljøet her i Bergen. Vi hadde et par
5529 Skolelinux-sentrerte BLUG-møter for noen år siden, og det har vært et
5530 par Skolelinux-utviklersamlinger her.

5532 <p

>Hva er fordelene med Skolelinux slik du ser det?
</strong

5534 <p
>Jeg bruker dessverre ikke Skolelinux daglig. Men slik jeg kjenner
5535 prosjektet har det vært i stand til å ta opp i seg det beste av fri
5536 programvare i mange kategorier, så fra et sysadmin-perspektiv ser det
5537 ut som en svært behagelig sak. For brukerne er det vel både en fordel
5538 og en ulempe at det ikke er Windows. Men vi håper at fordelene med et
5539 fritt system etterhvert vil bli åpenbare for både elever, lærekrefter
5540 og foreldre.
</p
>
5542 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
5544 <p
>Vel, ulempen er vel først og fremst at andre aktører med mer
5545 kapitalmuskel har klart å etablere seg som det både lærere og foreldre
5546 føler seg trygge på, selv om det etter mitt hode ikke er noen grunn
5547 til å være spesielt trygg på de kommersielle alternativene.
</p
>
5549 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
5551 <p
>Når jeg får bestemme helt selv, bruker jeg kun fri programvare. Da
5552 helst med vekt på ting som kjører greit på OpenBSD. Hjemme er det
5553 OpenBSD, Ubuntu eller FreeBSD vi bruker. På skrivebordet er det en
5554 avveining mellom Gnome, KDE eller hva-det-nå-heter som er
5555 standardvalget i Ubuntu, ellers er det de kjente tingene som
5556 LibreOffice, Emacs, mplayer. På server er det selvfølgelig Apache,
5557 for overvåking både OpenNMS og Nagios (det bare ble sånn, og
5558 forskjellige siter). Jeg skriver til tider om slikt jeg holder på med
5560 <a href=
"http://bsdly.blogspot.com
">http://bsdly.blogspot.com
</a
>.
</p
>
5562 <p
>Men vi må nevne at selv vi har en Microsoft-ting som vi slår på når
5563 vi av en eller annen grunn må. Det betyr igjen vanligvis når en
5564 mobiltelefon eller en annen lukket elektronisk dings krever kontakt
5565 via en slik for å få oppdateringene sine.
</p
>
5567 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
5568 skoler til å ta i bruk fri programvare?
</strong
></p
>
5570 <p
>Hadde vi hatt det rette svaret på det spørsmålet, så hadde vi
5571 gjerne hatt Skolelinux som førstevalg på alle skoler ;)
</p
>
5573 <p
>Men jeg tror vi må legge vekt på flere forskjellige ting. En helt
5574 sentral sak er å fokusere på fri programvare og åpne standarder som de
5575 demokratiske verdiene de faktisk er. Det har kanskje kommet litt for
5576 mye i bakgrunnen i forhold til strevet etter å lage det mest mulig
5577 'brukervennlige
' systemet. Det er en tung vei å gå, så det er
5578 forståelig at freenix-aktivister heller velger å skrive kode og annet
5579 som er mer lystbetont. Mer praktisk tror jeg vi må gjøre i alle fall
5580 to ting: For det første sørge for å fortsette med å levere det best
5581 mulige frie produktet, slik at det er lett å både komme i gang og
5582 holde systemene i daglig drift, og for det andre
2) spore opp mulige
5583 aktivister der de finnes, via lokale brukergrupper, sosiale medier
5584 eller annet og sørge for at de fortsetter å være aktive. Mer og
5585 mindre uformelle treff kan være nyttig i tillegg til de mer
5586 organiserte møtene med foredrag, konferanser og utviklersamlinger.

</strong
></p
>
5611 <p
>Jobbet i IBM fra
2000, og da spesielt med Linux. Dette var da et av
5612 de mest tydelige linux prosjektene i Norge, og her ønsket jeg å
5613 bidra. Var aktivt med i prosjektet i
4-
5 år.
</p
>
5615 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
5617 <p
>Fordelene slik jeg ser det er den sentraliserte driftmodellen, og
5618 alle de vel gjennomtenkte løsningene som er inkludert i denne
5619 løsningen. Samtidig er det basert på en stabil, og godt kjent
5620 plattform. Dette vil si at man har en løsning som skal være mye
5621 tilgjengelig, og hvor det er relativt enkelt å få tak i personer som
5622 kan mye om den grunnleggende plattformen.
</p
>
5624 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
5626 <p
>De største utfordringene med en løsningen er at den er intensiv på f.eks
5627 nettverk. I seg selv ikke et problem for en enkelt skole, men skal løsningen
5628 kjøres i større skala, med sentraliserte servere, så gir dette noen
5629 utfordringer.
</p
>
5631 <p
>Utifra hva jeg har sett på større installasjoner så er det ikke så
5632 enkelt å skjønne, hva som bør gjøres for at den skal skaleres opp, og
5633 da ta godt vare på alle sider av dette, ikke bare mer server å fordele
5634 last/trykk, men hvordan også beholde robustheten og fleksibiliteten i
5635 løsningen.
</p
>
5637 <p
>En annen utfordring er at stadig flere produkter som skal brukes i
5638 skoleløsningen ikke er laget til å kunne brukes i en
5639 skolelinuxløsning. Det blir derfor fort mye skreddersøm i de
5640 forskjellige installasjonene, for å få diverse pedagogiske programmer,
5641 webløsninger, smartboards, m.m. til å fungere. Man er også en for
5642 liten kundebase til at leverandørene ønsker å gjøre noe med
5643 utfordringen. Problemet overlates til oss.
</p
>
5645 <p
>Det er også en kontinuerlig utfordring rundt problemet med å holde
5646 programvare på stabile versjoner, kontra å få ny funksjonalitet. Dette
5647 er jo en konflikt mellom oss som ønsker å drifte en stabil, og
5648 kostnadseffektiv løsning, mot sluttbrukerne som ønsker seg funksjoner
5649 det er vant med fra andre løsninger, eller som de må ha for at et
5650 eller annet nytt produkt skal fungere i løsningen. Dette er en
5651 utfordring også for andre plattformer.
</p
>
5653 <p
>En siste utfordring som ikke har noe med løsningen å gjøre, men med
5654 det omkringliggende miljøet denne skal kjøre i, er at de enhetene som
5655 skal drifte dataløsninger for kommuner og fylkeskommuner begynner å
5656 profesjonaliseres, og er da avhengig av å ha standard løsninger for å
5657 drifte store brukermasser. MS er selvsagt klar over dette, og har jo
5658 nå flere områder de begynner å bli veldig dominerende på. Den største,
5659 og mest problematiske er katalogtjenesten. Man får snart ikke tak i
5660 større løsninger som ikke krever en AD. Når man da har store enheter
5661 som drifter både kommunalt ansatte og skoler, så vil det være et
5662 stordriftargument å standardisere på en katalog tjeneste, og da har
5663 man ikke noe valg. Her er alle slike driftsenheter for små til å få
5664 gjort om på dette. Her burde konkurransemyndighetene kommet på
5665 banen. Men konkurransetilsynet i USA griper sjeldent (og ikke før det
5666 har gått veldig lang tid) inn i monopolsituasjoner så lenge
5667 monopolisten er et amerikansk firma, så da har vel ikke andre
5668 myndigheter så mye de skulle ha sagt....

>Argumentene som ofte har vært brukt om at ting koster mindre holder
5687 ikke mål når man ser på hva som faktisk koster penger. Det er de
5688 ansatte som er en kostnadsdriver. Det vil si at hvis man har et system
5689 som den ansatte kan, så vil en kostnad på dette systemet kunne
5690 forsvares ganske mye ved at den ansatte gjør dette raskere og
5691 effektivt. Også uten å måtte eventuelt leie inn folk.

>Jeg syns det er viktigere å fokusere på prinsippet med å velge fri
5694 programvare, men det er også et felt hvor man fort møter lite
5695 forståelse blant de ansatte i skolen.
</p

5697 <p
>Her må nok strategien fortsette å være at de sentrale myndighetene
5698 må sende tydelige signaler for hva de ønsker at offentlige enheter
5699 skal gjøre. Det var mye positivt på gang ang. dette for et par år
5700 siden. Både med eNorge og eKommune planene, men dette syns jeg har
5701 stoppet opp. En del av dette kan jo kanskje være usikkerheten som
5702 etter hvert har blitt, når man har sett kompleksiteten i de
5703 prosjektene som har blitt igangsatt. Det har også blitt noe usikkerhet
5704 i markedet ref. Sun, Oracle, Novell, Microsoft m.m. Samtidig har jo
5705 også de proprietære programleverandørene sørget for å endre sine
5706 lisenser slik at man uansett ikke slipper unna kostnaden til deres
5707 produkter, selv om man skulle velge alternativer. Da er det økonomiske
5708 argumentet, som jeg nevnte tidligere, spilt ganske godt ut over
5709 sidelinjen.

5733 hadde vel hørt om prosjektet i media før en gjeng i Trondheim startet
5734 opp SPIST, Skolelinux-prosjektet i Sør-Trøndelag, hvor vi hjalp noen
5735 skoler i nærområdet med å installere Skolelinux og finne brukt
5736 IT-utstyr til disse. Det var moro å gjøre noe praktisk for å spre
5737 Skolelinux, og å se hvor fort gjort det var å sette opp utrangerte
5738 klientmaskiner og få disse opp som tynnklienter på helt nye datasaler
5739 på skolene, kun med kostnaden til servere.

5743 <p
>Det er et system spesielt skreddersydd for drift av et stort antall

5752 litt gammel programvare pga. at den følger Debian sine utgivelser.
5753 Kanskje man skulle vurdert en versjon basert på Ubuntu eller andre

5770 fleksibilitet, åpenhet og ikke låsing til en leverandør framfor sparte
5771 lisenskostnader, samt programvarens kvalitet og fortrinn, og at den
5772 fritt kan brukes på et ubegrenset antall PC-er, også hjemme hos
5773 elevene. En bør også forbedre den fri programvaren ved testing,
5774 bugrapportering og kodebidrag om man kan, og ikke anbefale programvare
5775 uten at man har forsikret seg at den har tilstrekkelig kvalitet,
5776 ellers kan man lett oppnå det motsatte. Tror en bør selge inn
5777 konseptet til fylkes-/statsnivå, kanskje med bidrag til
5778 utviklingsarbeid fra disse som alle landets skoler kan få glede

>Mine bloggposter om Linux i skolene i Norge førte til at inspektør
5789 og ildsjel på Harestad skole tok kontakt og fortalte at de bruker
5790 Linux på sin skole, og lurte på om de kunne bidra til å gjøre
5791 fordelene kjent. Riktig nok bruker de ikke
5792 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
> på denne skolen,
5793 men jeg synes dette er en god anledning til å gjøre flere fasetter
5794 rundt Linux-økosystemet kjent, og tok et lite intervju.
</p

5796 <p

5798 <p
>Mitt navn er Odin Hetland Nøsen og er en
70-modell. Jeg er bosatt i
5799 Stavanger og jobber nå på
9. året som undervisninginspektør på
5800 Harestad skole i Randaberg kommune (nabokommune til Stavanger).
</p

5802 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
5804 <p
>I
2002 begynte daværende IKT-ansvarlige og jeg et arbeid på skolen
5805 med å gå over fra Win98 til... noe annet. Vi testet en rekke
5806 forskjellige løsninger, deriblant Skolelinux, men endte opp med
5807 RedHat. Skolelinux var den gang ikke modent for det vi ville ha. Jeg
5808 har siden fulgt jevnlig med på hva skolelinux holder på med, men har
5809 hele tiden vært bedre fornøyd med vår egen
"standardiserte
" løsning på
5810 RedHat/CentOS og Fedora. Vi snuser for tiden på Ubuntu som løsning på
5811 klientsiden.
</p
>
5813 <p
>I dag har vi på skolen vår en større linux-løsning med
400 klienter
5814 som kjører en blanding av LTSP (tynnklient) og DRBL (tykk klient uten
5815 harddisk) med en masse tjenere på serverrommet. Vi drifter hele
5816 sulamitten selv med webtjener, eposttjener, webmail, filtjenere,
5817 virtuelle tjenere osv. Og IT-ansvarlig har en
80% stilling som
5818 IT-ansvarlig - og så er han KoH-lærer i de resterende
20% :-)
</p
>
5820 <p
>Du kan få en ide om hva vi holder på med om du går inn på
5821 <a href=
"http://www.gnuskole.no/
">http://www.gnuskole.no/
</a
>.
</p
>
5823 <p
>For å ta brodden av frykten for at ildsjeler gjør skolen sårbar om
5824 ildsjelene falle fra, har jeg forsikret kommunen og skolesjefen i
5825 Randaberg om at det finnes godt kommersielle tjenester vi kan benytte
5826 oss av - om det skulle bli nødvendig. Vi er tre stykker i kommunen som
5827 nå har
<strong
>god
</strong
> linux-kompetanse ift. å drifte et større
5828 system. IT-avdelingen i kommunen vil ikke ta på oss med ildtang -
5829 selv om vi nok har større IT-kompetanse mot linux enn det de selv har
5830 mot windows (de kjøper en
<strong
>masse
</strong
> konsulenttjenester
5831 fra ErgoGroup).
</p
>
5833 <p
>I kvantitet er Harestad og Grødem skole tilsammen et større
5834 IT-system enn resten av Randaberg kommune + Kvitsøy og Rennesøy, som
5835 kommunen også har driftsansvar for. Vi har som sagt rundt
800
5836 maskiner, mens kommunen med sitt driftsansvar har ansvar for rundt
500
5837 maskiner. Det er selvfølgelig litt forskjell i hvor kritiske
5838 tjenestene våre er, men det gir allikevel et litt rart bilde når
5839 IT-avdelingen overhode ikke er interessert i å snakke med oss om
5840 hvordan vi gjør ting :-)
</p

5842 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
5844 <p
>Fra linux-perspektivet (ikke bare Skolelinux) er det en fordel av
5845 systemet er basert på fri programvare - og dermed fritt i ordets mange
5846 betydninger. Det er alt vi trenger: stabilt, relativt enkelt å drifte
5847 (tross alt - et større windowssystem er ikke enkelt å holde live det
5848 heller), rimelig i innkjøp og drift, og sist, men ikke minst, det er
5849 moderne for sluttbruker! Linux, i sine mange varianter,
5850 <strong
>ser
</strong
> nytt ut, fordi det hele tiden blir
5851 oppdatert. Derfor lever systemet opp til hvordan elever forventer at
5852 et moderne GUI skal være (i motsetning til WinXP :-).
</p
>
5854 <p
>Vi var veldig pragmatiske da vi begynte med linux i skolen. Det var
5855 billig, det fungerte og kunne bruke alle de gamle windows-maskinene
5856 som
"nye
" tynne klienter. I dag er vi mer bevisste fri
5857 programvare-tilhengere. Vi har oppdaget hva det er - og vi liker
5860 <p
>En av de
<strong
>store
</strong
> fordelene med fri programvare er at
5861 vi kan installere tjenester vi ønsker å tilby brukerne våre - uten å
5862 måtte tenke på om vi har råd til lisensene (fordi det er ingen). Alt
5863 vi setter i produksjon er ut i fra brukernes behov og vår kapasitet
5864 til å drifte dem. Vi skreddersyr tjenestene etter behovet og dermed
5865 trenger vi ikke ende opp med å kjøpe en pakke der vi egentlig bare var
5866 interessert i en liten del av den.
</p
>
5868 <p
>Bruk av linux frigjør ikke økonomiske midler, fordi midlene til IKT
5869 i skole er for få i utgangspunktet - men vi får så
5870 <strong
>mye
</strong
> mer igjen for dem når vi bruker en linux-løsning
5871 fremfor en windows-løsning. I praksis ser vi at vi måtte ut med det
5872 dobbelte på budsjettet vårt om vi skulle hatt en tilsvarende
5873 windows-løsning, som det vi i dag drifter med linux.
</p
>
5875 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
5877 <p
>Ikke all pedagogisk programvare er tilgjengelig. Det er en del
5878 programvare i skolen som er laget med utviklerverktøy som bare virker
5879 i windows, f.eks. Drillpro, LingDys/LingWrite. Det er også
5880 "programmer
" som bare virker om du har tilgang til Microsoft Office,
5881 f.eks. AskiRaski.
</p
>
5883 <p
>Vi sliter også litt med at video-codecer ikke alltid er like lett å
5884 få opp å gå på klientene. Det er alltid en eller annen videosnutt fra
5885 nrk.no som ikke er så samarbeidsvillig, uansett mediaplayer.
</p
>
5887 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
5889 <p
>Alt :-) På skolen bruker vi det som finnes og som er nyttig. Det vi
5890 bruker mest er Firefox (jobber med Chrome, fordi det er
5891 <strong
>mye
</strong
> raskere med Flash enn Firefox), OpenOffice (skal
5892 over til LibreOffice), GIMP osv. Standardpakken av
5893 sluttbrukerprogrammer.
</p
>
5895 <p
>På tjenernivå bruker vi OpenWebMail (skal over til Zimbra), Exim
5898 <p
>Personlig bruker jeg de fleste programmer over flere plattformer,
5899 men jeg har lagt meg til en vane å prioritere bruken av fri
5900 programvare også i Windows
7 og OSX.
</p
>
5902 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
5903 skoler til å ta i bruk fri programvare?
</strong
></p
>
5905 <p
>Jeg er langt i fra sikker. For det første handler det mye om at
5906 IKT-avdelingen i kommunen ofte er de som styrer hva som er IKT på
5907 skolene - og de liker å bruke avtalene med Microsoft, som de garantert
5908 har fra før. Dessuten - Select
6-avtalen til skolene gjør Microsoft
5909 skvettbillig.
</p
>
5911 <p
>Vi la vekt på effektiv drift av systemet - og at vi kunne øke
5912 antall maskiner uten å måtte øke budsjett for utstyr eller personell
5913 særlig mye, enn om vi hadde gått for en Microsoft-løsning. I praksis
5914 ser vi at en ren linux-installasjon driftes til halve prisen av en
5915 Microsoft-løsning.
</p
>
5917 <p
>Vi har i praksis også sett at det lærerne (og elevene) liker er at
5918 vi tilbyr
<strong
>veldig
</strong
> mange tjenester som ikke er så
5919 vanlige i en Microsoft-løsning. Det er ikke så vanlig at
5920 <strong
>elevene
</strong
> også har epost, hjemmekontor osv. Det har vi
5921 også brukt som et vellykket argument mot Microsoft.
</p
>
5923 <p
>Den beste måten er selvfølgelig at noen bare bestemmer
5924 det. Problemet er å få dem som har makt til å bestemme det til faktisk
5925 å gjøre det ;-)

6015 på
6 år. Jobber i Oslo som Global Sales Executive hos Varnish Software
6016 og til daglig har jeg kontakt med kunder fra hele verden. Min
6017 forkjærlighet for fri programvare har gjort at jeg har nå flere års
6018 erfaring med salg av slike løsninger (bl.a. fra Redpill Linpro og
6019 Freecode) og mye innsikt og kunnskap om det globale IT-markedet.
6020 Ellers er jeg involvert i flere prosjekter bl.a. er jeg Ubuntu
6021 Community medlem, kontaktpersonen for Ubuntu Norge og driveren av
6022 SpreadUbuntu marketing prosjektet og nå fersk styremedlem i FRISK. Jeg
6023 har brukt GNU/Linux siden
1997.

</strong

6027 <p
>Som Debian bruker siden slutten av
90-tallet var det uunngåelig å
6028 ikke komme bort i Skolelinux. Dette var vel i slutten av
2001 når jeg
6029 var student ved UiO. Flere år senere fikk jeg lastet og testet Venus
6030 (Skolelinux
1.0) på release dagen.

6032 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong

6034 <p
>Fri programvare bygges sten for sten i det åpne, slik at koden og
6035 prosessen den lages på kan gjennomskues av andre enn de som har laget
6036 det. Det er et vitenskapelig og gjennomsiktig måte å lage programvare
6039 <p
>Skoler i vårt samfunn skal være steder hvor vitenskapelig kunnskap
6040 deles til alle. I dag har vi ikke et vitenskapelig tilnærming til
6041 hvordan programvaren som brukes på skolen lages. Skolelinux bringer
6042 inn at slik tilnærming i skoleverkets klasserom, siden
6043 operativsystemet er en åpent platform som gir skolene muligheten til å
6044 dra nytte av programvare som er laget av tusenvis av mennesker verden
6045 rundt og som gir elevene så vel som lærerne muligheten til å bruke,
6046 dele, forandre og forbedre OSet sitt uten begrensninger. I den
6047 forbindelsen representerer Skolelinux også konkrete resultater utfra
6048 samhandling på tvers av grenser.
</p
>
6050 <p
>Når det gjelder de tekniske fordelene av Skolelinux er jeg sikker
6051 på at andre enn meg har allerede beskrevet disse bedre enn det jeg
6052 kan. Men jeg kan likevel tilføye noe: Skolelinux som sådan er en
6053 community-drevet operativsystemplatform. Som i ethvert
6054 community-prosjekt har alle Skolelinux brukere muligheten til å
6055 påvirke retning av prosjektet og resultatet som gjenspeiles i
6056 programvaren. Dette kommer sjeldent frem og jeg mener at det er noe
6057 som burde fokuseres mer på.

>Jeg husker en leverandør av et stort OS for noen år siden mente at

6133 <p
>Det største hinderet er det vi opplever på andre områder rundt
6134 fri programvare, nemlig kunnskap. For mange er det trygt å velge det vi
6135 alltid har valgt. Fordi leverandørene rundt oss sitter på den kunnskapen og
6136 de vi støtter oss på har den samme. Hvis vi klarer å riste løs litt og
6137 glemme gamle kriger mellom operativsystemer og leverandører, men sette ned
6138 hva som er viktig og velge ut fra det, så hadde man kanskje kommet ut med
6139 litt andre resultat. Jeg tror IT-folk er konservative og velger tradisjonelt
6140 og det er synd.

6147 skyen og setter pris på alt jeg slipper egen klient til. Derfor er
6148 jeg veldig sjarmert av små kjappe operativsystemer som krever minimalt
6149 av maskinvaren.

6157 å gå sammen. Det er til slutt LÆRING det dreier seg om, og da må man

>Sturle Sunde, ansvarleg for skulenettet i Flora kommune. Eg driv,
6176 vidareutviklar og er andrelinje brukarstøtte for datanettet ved
6177 skulane i Flora kommune.
10 skular og meir enn
700 maskiner med
6178 Linux, medrekna tynnklientar. Tidlegare jobba eg i mange år med
6179 unix-drift ved Universitetets senter for informasjonsteknologi ved
6180 Universitetet i Oslo.

6182 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p

6184 <p
>Det er vanskeleg å svare konkret på. Eg har drive med Unix og Linux i
6185 alle år, og Skulelinux er eit godt kjent prosjekt i miljøet. Det var
6186 først i
2008, då eg tok til i min noverande jobb, at eg fekk bruk for
6187 Skulelinux for alvor.
</p
>
6189 <p
>Jobben min skulle vere drift av eit nytt skulenett i Flora kommune,
6190 levert av eit firma eg ikkje vil reklamere for. Systemet skulle vere
6191 ferdig levert i september året før. Dette viste seg å ta mykje lenger
6192 tid, og i haustferien
2008 hadde dei endå ikkje klart å få opp ei
6193 fungerande løysing. Situasjonen var prekær for den største skulen i
6194 kommunen med meir enn
500 elevar på ungdomssteget. Skulen hadde brukt
6195 Skulelinux før, og var tilfredse med det. No hadde dei vore utan
6196 fungerande datasystem i nesten eit år. Difor fekk eg opp ein ny tenar
6197 utanfor prosjektet og installerte Skulelinux på den. Etter litt
6198 justering av konfigurasjonen med god hjelp av #skolelinux på IRC, var
6199 den nye tenaren oppe og gjekk med både tynne og halv-tjukke klientar.
6200 Autentisering gjekk mot det nye systemet, slik at elevar og lærarar
6201 framleis har same brukarnamn og passord over alt. Dette berre
6202 fungerte, og vi bestemte oss for å erstatte delar av løysinga vi
6203 skulle få levert med Skulelinux.
</p
>
6205 <p
>Det høyrer med til historia at det nye systemet eg skulle drive frå
6206 januar
2008 endå ikkje er ferdig levert. Dei jobbar med saka, seier
6207 dei, og har von om å fullføre leveransen i løpet av
2011.
</p
>
6209 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6211 <p
>Det er veldig mange. Eg skal ta nokre få.
</p
>
6213 <p
>Den viktigaste fordelen er at det igrunn berre er ei maskin å passe
6214 på, og det er tenaren. Med andre løysingar har ein gjerne programvare
6215 og anna som skal vedlikehaldast på kvar enkelt maskin. Med Skulelinux
6216 kan alle feil rettast og alle program oppgraderast på alle maskiner
6217 samstundes ved å gjere endringa som må til på tenaren. Eg kan sitje
6218 på kontoret og passe på alle tenarane i kommunen derifrå.
</p
>
6222 <li
>Tynne klientar gjer det mogleg å bruke eldre utstyr lenge, so lenge
6223 tenaren er sterk nok. Ein liten tenar med eit par halv-moderne CPUar
6224 og
2 GiB RAM held lenge for eit typisk klasserom med
30 tynnklientar,
6225 og det er lett å utvide med fleire.
6227 <li
>Halvtjukke klientar gjer det mogleg å utnytte kapasiteten i litt
6228 nyare maskiner betre, og avlaste tenaren. Ingenting vert installert
6229 lokalt på desse heller, og harddisken kan gjerne koblast frå. Gode
6230 halvtjukke klientar kan kjøpast brukt for under
1000-lappen, og det er
6231 heile kostnaden. Ingen lisensar eller anna på toppen, og det er ikkje
6232 krav til kraftigare tenar heller.
6234 <li
>Det er Linux. Vi har ikkje noko kluss med drivarar, dei berre er
6235 der. Heller ikkje med virus, dei finst i realiteten ikkje. Eller med
6236 elevar som klussar med installert programvare, for dei klarar ikkje å
6237 øydeleggje for nokon andre enn seg sjølve.
6241 <p
>Skulelinux er lagt opp til å vere veldig lett å installere rett ut
6242 av boksen på ein heil skule av ein interessert lærar. Det er ofte ei
6243 god løysing for skulen. Å ha nokon til stades som kjenner systemet og
6244 kan forklare enkle ting eller løyse problem der og då, er uvurderleg
6245 viktig for ein stressa lærar fem minutt før det ringer inn.
</p
>
6247 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6249 <p
>All den ferdige konfigurasjonen gjer det tungvint å tilpasse
6250 Skulelinux til eit system som skal fungere saman med mange andre
6251 installasjonar i eit felles datanett for skulane i ein kommune. Det
6252 heile er prekonfigurert for ein skule, og utviding til mange skular
6253 med eigne tenarar er ikkje berre enkelt.
</p

6255 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
6257 <p
>Eg brukar mest alle små hjelpeprogram som føl med operativsystemet,
6258 samt scriptspråket perl. Elles er Firefox/Iceweasel, Gnome-terminal
6259 og ssh i kontinuerleg bruk. Av Linux-distribusjonar brukar eg både
6260 Debian, Ubuntu, SuSE og RedHat dagleg. Eg prøvar å finne det verktyet
6261 som passar best til kvar del av jobben.

6264 skoler til å ta i bruk fri programvare?
</strong

6266 <p
>Det er to målgrupper ein må sikte mot. Det eine er alle skulane som
6267 manglar eller har eit lite tilfredsstillande opplegg i dag, og ikkje
6268 har råd til å kjøpe noko nytt og blankpussa opplegg. Der er det om å
6269 gjere å gjere det enkelt for skulane å finne Skulelinux, og gjere det
6270 enkelt for dei å få hjelp til installasjon på skulen. Gjerne med
6271 lokale kontaktpersonar. Her er det dugnadsinnsats som må til, for
6272 desse skulane har ikkje råd til å betale for dette.
</p
>
6274 <p
>Den andre og kanskje viktigare målgruppa er dei meir eller mindre
6275 profesjonelle kundane. Alle store offentlege innkjøp, inkludert
6276 innkjøp av nytt datasystem for skular, må ut på offentleg anbod.
6277 Offentlege anbod er mykje meir lukka enn dei gjev inntrykk av, og både
6278 regelboka og boka med triks for å sminke tilbodet er tjukk. Det er
6279 vanskeleg å komme inn utan eit solid salsapparat i ryggen. Kanskje
6280 Skulelinux skulle prøve aktivt å få seg eit partnarskap med eit av dei
6281 store som gjerne vil sterkare inn på den offentlege IT-marknaden?
6282 Nokon som kjenner triksa og har krefter til å ta opp kampen mot både
6283 dårlege anbod og Rudolf Blostrupmoen IT AS. Leveranse til skulane i
6284 ein kommune er ein god måte å få ein fot inn døra som leverandør til
6285 ein lukrativ kommunemarknad som kjøper alle tenester. Ta kontakt med
6286 nokon som er passeleg store og ikkje er Microsoft-partnar, og fortell:
6287 «Vi har eit ferdig produkt som du kan selje. Nei vi skal ikkje ha for
6288 det. Du kan gjerne gjere kva du vil med det, berre vi får lov til å
6289 hjelpe deg. Målgruppa er alle kommunar, og det er noko dei vil ha.
6290 Det er eit godt produkt, brukt av mange og godt likt.»

6310 40% lærer og
60% IKT med Windows XP, Win2003 server og et regionalt
6311 IKT-regime som legger premissene og begrensingene for hva vi kan gjøre
6312 på skolen.

</strong

6316 <p
>Jeg leste en artikkel om en dugnadsinstallasjon av Skolelinux på en
6317 skole på Jæren et sted. Tanken om dugnad og frihet appellerte til
6318 meg. Da vi skulle bygge ny skole var det en del vi måtte spare på,
6319 fordi vi beveget oss mot en kostnadssprekk. Kabling og investering i
6320 PC-er var en av tingene vi sparte på. Derfor kjøpe vi
72 pc-er for
390
6321 pr stk. En filtjener og en applikasjonsserver.

6323 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6325 <p
>Fordelen er at så mye er satt opp fra starten. I tillegg er det
6326 tydelig at pakka er laga for skoleverket. Brukerne har egne
6327 skrivebord, tilgang på mange gode verktøyprogrammer. Vi slipper å
6328 tenke på virus. Brukerne har ikke mulighet til å ødelegge
6329 klientoppsett, men har gode muligheter til å endre eget oppsett. Dette
6330 tror jeg er inspirerende og kjekt for mange brukere. Mappestrukturen
6331 er ferdig og det er
"enkelt
" å designe lokale mappestrukturer via
6332 skeleton. Noen av oss i skoleverket mener skolen skal være en
6333 "mot-kultur
". Da er Skolelinux et av valgene man kan ta. Et annet er å
6334 spise på indisk restaurant i stedet for Mc Donald
's når vi er på bytur
6335 osv.. Ordene deling, frihet, dugnad osv er positive ord i
6336 skoleverket. Det er viktig at elevene blir bevisst dette.

>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p

6340 <p
>Kompabiliteten er selvsagt et problem, selv om det er mindre nå enn
6341 før. For IKT-personer på skolene som skal drifte dette er det
6342 problematisk med kommandoer i terminalen. I tillegg er det alt for
6343 mange programmer i Skolelinux som ikke blir brukt. Jeg tror
6344 Skolelinux er tjent med å tone ned begrepet pedagogisk programvare.
6345 Slik jeg ser det finnes ikke denne kategorien programmer lengre slik
6346 de gjorde før, som frittsående programmer som installeres på en
6347 datamaskin eller på serveren. Det finnes en del spesialpedagogiske
6348 programmer, som Textpilot, LingDys, LingRight, AskiRaski, Ny i Norge
6349 osv. Men dette er programmer for enkelt-elever eller små grupper av
6350 elever. Det som bør være fokus er at alle undervisningsressurser som
6351 lages for nettet skal være nettleseruavhengig.

>Hvilken fri programvare bruker du til daglig?
</strong

6355 <p
>OpenOffice bruker jeg til vanlig kontorarbeide. VLC bruker jeg som
6356 videoavspiller og av og til streaming av film. Gimp bruker jeg i
6357 undervisningen til bildemanipulering. Firefox og Chrome er mine
6358 favoritt-nettlesere. Firefox har lenge vært førstevalget mitt, nå
6359 bruker jeg mest Chrome. Opplever den som raskere og smidigere enn
6360 Firefox. Ubuntu bruker jeg som dualboot på jobb-maskinen min i
6361 tillegg til at alle PCer hjemme har en eller annen Ubuntu-distribusjon
6362 installert. Jeg bruker Clonezilla på Ubuntu
10.04 til kloning av
6363 datamaskiner på jobb. Det er selvsagt en haug andre frie programmer
6364 jeg bruker men jeg bruker dem ikke daglig. Jeg kan ramse opp:
6365 recordmydesktop, cinelerra, acidrip, soundjuicer, audacity, NX
6366 (no-machine), Kino, Rythmbox...

6368 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
6369 skoler til å ta i bruk fri programvare?
</strong
></p
>
6371 <p
>Jeg tror oppsøkende virksomhet er den rette strategien.
6372 Ressurspersoner gjør avtaler med rådmenn, skolesjefer, rektorer. Det
6373 er slik konkurrentene gjør det. Fokuset i slike samtaler bør være
6374 kost-nytte. Dersom personer med økonomisk ansvar ser at de kan få
6375 like godt tilbud til mindre utgifter, tror jeg det er mulighet til å
6376 få innpass. Dersom de også kan få konkrete tilbud på drift i slike
6377 samtaler, vil de kanskje bli litt mer interesserte i hvor mye penger
6378 som faktisk går til IKT i skolene. Det er også viktig at vi ikke
6379 firer for mye på krav til datamaskiner. Det er flott at Skolelinux
6380 går på
"utrangert
" utstyr, men dette bør bare presenteres som et
6381 alternativ. Skolelinux-installasjoner med utrangert utstyr er ikke å
6382 foretrekke dersom man kan unngå det. Det skaper ikke entusiasme hos
6383 brukerne (elever og lærere) når de bruker gamle datamaskiner som går
6384 tregt. Det er kjempefint med skoler som har kommet seg frem til
6385 Skolelinux og fri programvare av seg selv, men de lever på nåde.
6386 Slike valg må fundamenteres hos skoleeier.

6421 av Skolelinux på en standard pc på Solneset skole i Tromsø. Denne var

2004. I denne planen ble det bestemt at Narvik kommune skulle
6431 bruke Skolelinux. Her ble det også satt av midler til kabling av god
6432 infrastruktur på alle skoler samt innkjøp av nye datamaskiner. Så i
6433 dag har vi
17 servere hvorav
13 er på Skolelinux, med ca
1500 klienter
6434 basert på tynne,

6516 pilotprosjekt med Skolelinux, som egentlig var og er en stor suksess,
6517 men det virker ut som det ikke skjer noe mer på. I tillegg var vi med

>Kommunen min har to omtrent jevnstore tettsteder, og en
6570 ungdomsskole i hvert av tettstedene. Den minste av disse har ca
300
6571 elever og til denne sogner det
3 barneskoler. Den største har ca
350
6572 elever og til denne sogner det
4 barneskoler.
</p
>
6576 <li
>Kommunen har i veldig lang tid forsømt IKT i skolen, og det har
6577 bare blitt gitt smuler i ny og ne. Det er kun den største av
6578 ungdomsskolene som har hatt en skikkelig datapark, og dette takket
6579 være en naturfaglærer som ble lei av å vente på kommunen. Det gjorde
6580 at vi bestemte oss for å ta ting i egne hender, og da vha
6581 skolelinux. En testinstallasjon med
10 gamle PCer ble gjort, og vi så
6582 raskt at dette var veldig lovende. Neste etappe var å gi alle lærere
6583 egen PC på arbeidsplassene sine (
2004), og så sette opp
16 PCer på to
6584 datarom. Vi har kun basert oss på å kjøpe inn brukte maskiner, og
6585 aldri dyrere enn
1000 kr pr klient. For to år siden så hadde vi
6586 klienter i alle klasserom, og totalt hadde vi da rundt
250 stk. Rundt
6587 40 klienter brukes av lærerne og kjører på en egen server. Elvene har
6588 resten, og kjører også en egen server. Servere har vi også kjøpt
6589 brukt,
2 år gamle servere koster
6-
7000 kroner.
</li
>
6591 <li
>Skolen vår er et relativt gammelt bygg, men en meget dyktig
6592 vaktmester har sammen med IKT-ansvarlig/Naturfaglærer lagt kabler til alle
6593 rom. Gradvis har vi byttet ut billige svitsjer med mer solide saker
6594 som er mulig å fjernstyre.
</li
>
6596 <li
>Vi har i all hovedsak greid å få dette til over eget budsjett, men
6597 vi har også passet på å få penger når de andre skolene har fått
6598 bærbare PCer til lærere osv.
</li
>
6600 <li
>Vår IKT-ansvarlig har gjort (og gjør) en fenomenal jobb, og vi har
6601 en maskinpark som de andre av kommunens skoler bare kan drømme
6606 <p
>Så skjer det som ofte skjer. Det kommer en eller annen
6607 selger/blåruss og skal fikse ALT. I vårt tilfelle betyr dette også
6608 sentralisering av drift. Den ny-ansatte på kommunens IT-avdelingen
6609 skal også ha jobb, og ser for seg å ta over skoledriften. Kommunen
6610 kjøper inn eksterne driftstjenester, og nekter i samme slengen å ta
6611 hensyn til skolen vår. Dette til tross for at vi alene har like mange
6612 datamaskiner som de andre til sammen.
</p
>
6616 <li
>Det blir krevd at vi skal innlemmes i de kommunale systemet, og
6617 det er VI som får ansvar for at dette kommer på plass. Og det er her
6618 de horrible tingene begynner å skje.
</li
>
6620 <li
>Det settes opp en lukket Exchange server som gjør av vi ikke kan
6621 hente epost for våre ansatte. Og det kreves at vi finner løsning på
6624 <li
>Det velges sak arkivsystem som vi pålegges å bruke, noe som gjør
6625 at vi må bruke en terminalløsning mot kommunal server. Ikke i seg selv
6626 et problem i følge IKT-ansvarlig hos oss. Men kommunens IT-avd nektet
6627 faktisk å åpne de porter OSV som vi måtte bruke.
</li
>
6629 <li
>Vi blir pålagt å flytte på innsiden av det kommunale
6630 nettverket. Dette gjorde at vi mistet hjemmekontor for lærere og
6631 elever. Å få åpnet porter i kommunal brannmur var ikke
6632 aktuelt. Mulighet for fjerndrift ble også vekk i samme slengen.
</li
>
6634 <li
>Vår LMS Moodle er ikke mulig å nå for elevene og lærerne.
6638 <p
>Den andre ungdomsskolen i kommunen begynner så å kreve at de skal
6639 få bedre datatetthet, og komme opp på et nivå som ligner det vi
6640 har. De ser at vi kan avholde eksamen hvor alle
10. klassingene får
6641 sitte ved hver sin PC. Og de har fått tilbakemelding (klager) fra VGS
6642 om manglende datakompetanse på elevene som kommer fra dem. Dette fører
6643 videre til at kommunen endelig innser at de må ta grep.
</p
>
6645 <p
>Grepet betyr sentralisering, og farvel til vår plattform får vi
6646 høre. Det blir gjort en rekke bestemmelser og vedtak som vi ikke får
6647 være en del av. Det blir helt klart at vi må redusere antall maskiner,
6648 og det skal satses på bærbare maskiner. Siden vi ikke har fått tatt
6649 del i prosessene som angår oss, så bruker vi fagforening. Vi har ikke
6650 blitt hørt i forbindelse med endringer som er betydelig for vår
6651 hverdag, og greier å stoppe omlegging. I tillegg så har vi et politisk
6652 vedtak i kommunen på at vi skal kjøre Linux på elevnett, og dette
6653 vedtaket kan ikke administrasjonen i kommunene helt uten videre
6654 tilsidesette.
</p
>
6656 <p
>I sum har dette gjort at vi har fått jobbe videre i fred. Og en del
6657 runder i kommunens kontrollutvalg har gjort det tydelig at vi har blitt
6658 systematisk motarbeidet.
</p
>
6660 <p
>I dag har de andre skolene fått sine bærbare maskiner til elever og
6661 lærere, men etter
2 år med innkjøring er det fremdeles problemer

6667 det er for mye arbeid å renske disse for innhold slik at juks ikke er

6676 å komme seg på nett. Og lagring på felles server er bare å glemme i
6677 perioder.

6681 <p
>Vi har slitt mye, kranglet og sloss. Ikke med tekniske problemer,
6682 men med omgivelsene rundt som vil oss til livs. Men det har vært verdt
6683 hver dråpe med svette, og timer med irritasjon. Men vi har begynt å få

6729 har også truet med å si opp jobben sin hvis det ikke ble tatt hensyn i
6730 større grad enn hva som har vært tilfelle. VI kan også dokumentere
6731 flere brudd på anbudsregler, og vi kjenner til at relativt store
6732 IT-leverandører som ikke har fått tatt del i disse anbudene, rett og
6733 slett ikke tør melde fra av redsel for å få et dårlig rykte.

6739 <p
>Jeg glemte å nevne at vi nå nesten ikke bruker tid på å drifte
6740 systemet vårt, noe som gjør at det aller meste av tid blir brukt til å
6741 støtte lærerne og elevene. F.eks så bruker vår IKT-ansvarlig den
6742 første timen på jobb,
0730-
0830 kun til å gå ute på arbeidsplassene
6743 til læreren. Dette for å kunne svare på små og store problem, gi tips
6744 og råd, eller bare for å plukke opp hva som er behovet ute i
6745 undervisningsarealene. Det er dessverre ikke slik at alle lærerne har
6746 nok digital kompetanse til å kunne formulere alle spørsmålene de har,
6747 men ved å kunne få vise eller lufte tanker med IKT-ansvarlig så er det
6748 utrolig hva som kommer fram.
</p
>
6752 <li
>Jeg ser at mange bruker økonomi som argument i forhold til å bruke
6753 SkoleLinux, og jeg skal ikke legge skjul på at det var dette som i
6754 utgangspunktet var årsaken til vårt valg. Men diskusjonene og kampen
6755 med kommunens IT-avdeling har gjort at vi har fått et noe annet
6756 fokus. Fordelene med drift og stabilitet, gjør at vi ville ha valgt
6757 samme løsning selv om den var dyrere. At vi slipper langt billigere
6758 unna, som følge av
0,- lisenskostnader og lave maskinvarekostnader, er
6759 bare en bonus.
</li
>
6761 <li
>Etter å ha kranglet oss til å få skikkelig oversikt over hva de
6762 andre skolene i kommunen bruker på IT, så har vi fått gehør for å få
6763 samme midler til innkjøp. Dette har gjort at vi nå kan kjøpe inn
6764 utstyr som de andre skolene bare kan se langt etter. Vi har nettopp
6765 kjøpt inn
3 videokamera i semiproff-klassen for å kunne lage film,
6766 samt sende live fra skoleteater/konserter. Vi har kjøpt inn digitale
6767 kompaktkamera til alle klassene. Vi har et team av lærere som skal i
6768 gang med å teste ut tablets på svake elever. Håpet et at teknologien
6769 kan være med på å gi noen av elevene litt mer motivasjon. Vi har kjøpt
6770 inn et halvt klassesett med pulsklokker, noe som har vist seg å være
6771 overraskende inspirerende for en del av elevene. Vi har også oss på
6772 fag på en høyskole litt lengre sør for oss, slik at
3 av oss nå skal
6773 ta faget
"Linux tjenestedrift
". Som inspektør og en del av skolens
6774 administrasjon er det veldig praktisk å kunne trå til hvis det
6775 kniper. Men IKT-ansvarlig har vært UTROLIG flink til å lage rene
6776 smørbrødlister for hvordan de mest vanlige driftsproblem løses, så det
6777 er lett for flere av oss å ta del i den daglige driften. Vi har svært
6778 stor nytte av lærling (som også hjelper to av naboskolene), men det er
6779 nesten blitt slik at det er om å gjøre å komme til først for å få løse
6780 problem. Det å få fingrene på problem og utfordringer er den aller
6781 beste læremester.
</li
>
6785 <p
>Når vi nå tar til med planlegging av ny skole, så vil det være med
6786 tanke på at det skal være mulig med datautstyr på alle plasser. Vi
6787 kommer i all hovedsak til å legge kabel til alle tenkelige og
6788 utenkelige plasser. WiFi koster tilnærmet NULL å sette opp i
6791 <p
>Vi har ikke vært noe flink til å bidra til SkoleLinux-prosjektet,
6792 vi har rett og slett vært for opptatt med vår egen kamp. Vi har hentet
6793 mye inspirasjon fra diskusjoner som har gått i det miljøet, og vi
6794 håper at vi nå framover kan få tid til å bidra. Vi er i ferd med å
6795 bytte ut en av serverne våre, og da vil denne trolig bli satt opp som
6796 testserver for neste versjon av Skolelinux. På den måten vil vi i alle
6797 fall kunne gi tilbakemeldinger og rapportere feil. I tillegg så vil
6798 det kanskje gi oss noen nye utfordringer, for som lærlingen vår sier:
6799 "Skolelinux er noe herk, det skjer jo ikke noe galt og hvordan skal

6828 a few applications and plug in selected pieces of hardware. When
6829 something fail, I make a note about this in the test matrix and move
6830 on. If I have some spare time I try to report the bug to the OS
6831 vendor, but as I only have the machines for a short time, I rarely
6832 have the time to do this for all the problems I find.

6931 <description><p
>In the latest issue of Linux Journal, the readers choices were
6932 presented, and the winner among the multimedia player were VLC.
6933 Personally, I like VLC, and it is my player of choice when I first try
6934 to play a video file or stream. Only if VLC fail will I drag out
6935 gmplayer to see if it can do better. The reason is mostly the failure
6936 model and trust. When VLC fail, it normally pop up a error message
6937 reporting the problem. When mplayer fail, it normally segfault or
6938 just hangs. The latter failure mode drain my trust in the program.
<p
>
6940 <p
>But even if VLC is my player of choice, we have choosen to use
6941 mplayer in
<a href=
"http://www.skolelinux.org/
">Debian
6942 Edu/Skolelinux
</a
>. The reason is simple. We need a good browser
6943 plugin to play web videos seamlessly, and the VLC browser plugin is
6944 not very good. For example, it lack in-line control buttons, so there
6945 is no way for the user to pause the video. Also, when I
6946 <a href=
"http://wiki.debian.org/DebianEdu/BrowserMultimedia
">last
6947 tested the browser plugins
</a
> available in Debian, the VLC plugin
6948 failed on several video pages where mplayer based plugins worked. If
6949 the browser plugin for VLC was as good as the gecko-mediaplayer
6950 package (which uses mplayer), we would switch.
</P
>
6952 <p
>While VLC is a good player, its user interface is slightly
6953 annoying. The most annoying feature is its inconsistent use of
6954 keyboard shortcuts. When the player is in full screen mode, its
6955 shortcuts are different from when it is playing the video in a window.
6956 For example, space only work as pause when in full screen mode. I
6957 wish it had consisten shortcuts and that space also would work when in
6958 window mode. Another nice shortcut in gmplayer is [enter] to restart
6959 the current video. It is very nice when playing short videos from the
6960 web and want to restart it when new people arrive to have a look at
6961 what is going on.

7420 bit harder that it could have been, because we set up the Xen virtual
7421 machines to get the virtual partitions from LVM, which as far as I
7422 know is not supported by KVM. So to migrate, we had to convert
7423 several LVM logical volumes to partitions on a virtual disk file.

5
7730 TB zfs volume we currently use to store DV video. Because of this, I
7731 finally got around to do a test installation of Debian/Squeeze with
7732 kfreebsd. Installation went fairly smooth, thought I noticed some
7733 visual glitches in the cdebconf dialogs (black cursor left on the
7734 screen at random locations). Have not gotten very far with the
7735 testing. Noticed cfdisk did not work, but fdisk did so it was not a
7736 fatal problem. Have to spend some more time on it to see if it is
7737 useful as a file server for NUUG. Will try to find time to set up a
7738 gnash buildbot slave on the Debian Edu/Skolelinux this weekend.

>Prioritising packages for the Debian Edu /

"http://www.skolelinux.org/
">Skolelinux
</a
> DVD, which is
7749 supposed provide a school with all the services and user applications
7750 needed on the pupils computer network has always been hard. Even
7751 schools without Internet connections should be able to get Debian Edu
7752 working using this DVD.
</p
>
7754 <p
>The job became a lot harder when apt and aptitude started
7755 installing recommended packages by default. We want the same set of
7756 packages to be installed when using the DVD and the netinst CD, and
7757 that means all recommended packages need to be on the DVD. I created
7758 a patch for debian-cd in
<a href=
"http://bugs.debian.org/
601203">BTS
7759 report #
601203</a
> to do this, and since this change was applied to
7760 the Debian Edu DVD build, we have been seriously short on space.
</p
>
7762 <p
>A few days ago we decided to drop blender, wxmaxima and kicad from
7763 the default installation to save space on the DVD, believing that
7764 those needing these applications are few and can get them from the
7765 Debian archive.
</p
>
7767 <p
>Yesterday, I had a look what source packages to see which packages
7768 were using most space. A few large packages are well know;
7769 openoffice.org, openclipart and fluid-soundfont. But I also
7770 discovered that lilypond used
106 MiB and fglrx-driver used
53 MiB.
7771 The lilypond package is pulled in as a dependency for rosegarden, and
7772 when looking a bit closer I discovered that
99 MiB of the
106 MiB were
7773 the documentation package, which is recommended by the binary package.
7774 I decided to drop this documentation package from our DVD, as most of
7775 our users will use the GUI front-ends and do not need the lilypond
7776 documentation. Similarly, I dropped the non-free fglrx-driver package
7777 which might be installed by d-i when its hardware is detected, as the
7778 free X driver should work.
</p
>
7780 <p
>With this change, we finally got space for the LXDE and Gnome
7781 desktop packages as well as the language specific packages making the
7782 DVD more useful again.

7794 raise money for the project is going well. The lower limit of
10
7795 signers was reached in
24 hours, and so far
13 people have signed it.
7796 More signers and more funding is most welcome, and I am really curious
7797 how far we can get before the time limit of December
24 is reached.
7800 <p
>On the #gnash IRC channel on irc.freenode.net, I was just tipped
7801 about what appear to be a great code coverage tool capable of
7802 generating code coverage stats without any changes to the source code.

7806 It is missing in Debian, but the git source built just fine in Squeeze
7807 after I installed libelf-dev, libdwarf-dev, pkg-config and
7808 libglib2.0-dev. Failed to build in Lenny, but suspect that is
7809 solvable. I hope kcov make it into Debian soon.

7817 school, including central infrastructure server, workstations, thin
7818 client servers and diskless workstations. A nice touch added
7819 yesterday is RDP support on the thin client servers, for windows
7820 clients to get a Linux desktop on request.

7830 popularity-contest numbers
</a
>, the adobe-flashplugin package the
7831 second most popular used package that is missing in Debian. The sixth
7832 most popular is flashplayer-mozilla. This is a clear indication that
7833 working flash is important for Debian users. Around
10 percent of the
7834 users submitting data to popcon.debian.org have this package
7835 installed.

7837 <p

">Skolelinux
7839 i bruk – Rapport for Hurum kommune, Universitetet i Agder og
7840 stiftelsen SLX Debian Labs
</a
>»), one of the most important problems
7841 schools experienced with
<a href=
"http://www.skolelinux.org/
">Debian
7842 Edu/Skolelinux
</a
> was the lack of working Flash. A lot of educational
7843 web sites require Flash to work, and lacking working Flash support in
7844 the web browser and the problems with installing it was perceived as a
7845 good reason to stay with Windows.
</p
>
7847 <p
>I once saw a funny and sad comment in a web forum, where Linux was
7848 said to be the retarded cousin that did not really understand
7849 everything you told him but could work fairly well. This was a
7850 comment regarding the problems Linux have with proprietary formats and
7851 non-standard web pages, and is sad because it exposes a fairly common
7852 understanding of whose fault it is if web pages that only work in for
7853 example Internet Explorer
6 fail to work on Firefox, and funny because
7854 it explain very well how annoying it is for users when Linux
7855 distributions do not work with the documents they receive or the web
7856 pages they want to visit.
</p
>
7858 <p
>This is part of the reason why I believe it is important for Debian
7859 and Debian Edu to have a well working Flash implementation in the
7860 distribution, to get at least popular sites as Youtube and Google
7861 Video to working out of the box. For Squeeze, Debian have the chance
7862 to include the latest version of Gnash that will make this happen, as
7863 the new release
0.8.8 was published a few weeks ago and is resting in
7864 unstable. The new version work with more sites that version
0.8.7.
7865 The Gnash maintainers have asked for a freeze exception, but the
7866 release team have not had time to reply to it yet. I hope they agree
7867 with me that Flash is important for the Debian desktop users, and thus
7868 accept the new package into Squeeze.

7910 har vært rullet ut i noen måneder nå, og så vidt jeg fikk vite før
7911 sommeren skulle alle skoler ha nytt opplegg på plass før oppstart nå i
7912 høst. På alle skolene skal en kunne velge ved installasjon om en skal
7913 ha Windows eller Skolelinux på maskinene, og en kan i tillegg
7914 PXE-boote maskinene over nett som tynne klienter eller diskløse
7915 arbeidsstasjoner. Jeg er spent på hvor mange skoler som velger å ta i
7916 bruk Skolelinux, og gleder meg til å se hvordan dette utvikler seg.
7917 Løsningen leveres av

7921 via Skolelinux Drift AS siden prosjektet starter. Jeg synes det er
7922 fantastisk at Skolelinux er kommet så langt siden vi startet i
2001 at
7923 alle elevene i Osloskolene nå skal få mulighet til å bruke

7939 looking into alternatives for home directory access here at the
7940 University of Oslo, and one of the options is sshfs. My friend
7941 Finn-Arne mentioned a while back that they had used sshfs with Debian

7943 where, and he mentioned that sshfs failed to handle umask properly.

8042 <description><p
>As reported earlier, the last few days I have looked at how Debian
8043 Edu clients are configured, and tried to get rid of all hardcoded
8044 configuration settings on the clients. I believe the work to be
8045 mostly done, and the clients seem to work just fine with dynamically
8046 generated configuration.
</p
>
8048 <p
>What is the point, you might ask? The point is to allow a Debian
8049 Edu desktop to integrate into an existing network infrastructure
8050 without any manual configuration.
</p
>
8052 <p
>This is what happens when installing a Debian Edu client here at
8053 the University of Oslo using PXE. With the PXE installation, I am
8054 asked for language (Norwegian Bokmål), locality (Norway) and keyboard
8055 layout (no-latin1), Debian Edu profile (Roaming Workstation), if I
8056 accept to reformat the hard drive (yes), if I want to submit info to
8057 popcon.debian.org (no) and root password (secret). After answering
8058 these questions, the installer goes ahead and does its thing, and
8059 after around
50 minutes it is done. I press enter to finish the
8060 installation, and the machine reboots into KDE. When the machine is
8061 ready and kdm asks for login information, I enter my university
8062 username and password, am told by kdm that a local home directory has
8063 been created and that I must log in again, and finally log in with the
8064 same username and password to the KDE
4.4 desktop. At no point during
8065 this process did it ask for university specific settings, and all the
8066 required configuration was dynamically detected using information
8067 fetched via DHCP and DNS. The roaming workstation is now ready for
8070 <p
>How was this done, you might wonder? First of all, here is the
8071 list of things that need to be configured on the client to get it
8072 working properly out of the box:
</p
>
8075 <li
>IP address/netmask and DNS server.
</li
>
8076 <li
>Web proxy URL.
</li
>
8077 <li
>LDAP server for NSS directory information (user, group, etc).
</li
>
8078 <li
>Kerberos server for PAM password checking.
</li
>
8079 <li
>SMB mount point to access the network home directory. (*)
</li
>
8080 <li
>Central syslog server to send syslog messages to. (*)
</li
>
8081 <li
>Sitesummary collector URL to submit info to central server. (*)
</li
>
8084 <p
>(Hm, did I forget anything? Let me knew if I did.)
</p
>
8086 <p
>The points marked (*) are not required to be able to use the
8087 machine, but needed to provide central storage and allowing system
8088 administrators to track their machines. Since yesterday, everything
8089 but the sitesummary collector URL is dynamically discovered at boot
8090 and installation time in the svn version of Debian Edu.
</p
>
8092 <p
>The IP and DNS setup is fetched during boot using DHCP as usual.
8093 When a DHCP update arrives, the proxy setup is updated by looking for
8094 http://wpat/wpad.dat and using the content of this WPAD file to
8095 configure the http and ftp proxy in /etc/environment and
8096 /etc/apt/apt.conf. I decided to update the proxy setup using a DHCP
8097 hook to ensure that the client stops using the Debian Edu proxy when
8098 it is moved outside the Debian Edu network, and instead uses any local
8099 proxy present on the new network when it moves around.
</p
>
8101 <p
>The DNS names of the LDAP, Kerberos and syslog server and related
8102 configuration are generated using DNS information at boot. First the
8103 installer looks for a host named ldap in the current DNS domain. If
8104 not found, it looks for _ldap._tcp SRV records in DNS instead. If an
8105 LDAP server is found, its root DSE entry is requested and the
8106 attributes namingContexts and defaultNamingContext are used to
8107 determine which LDAP base to use for NSS. If there are several
8108 namingContexts attibutes and the defaultNamingContext is present, that
8109 LDAP subtree is used as the base. If defaultNamingContext is missing,
8110 the subtrees listed as namingContexts are searched in sequence for any
8111 object with class posixAccount or posixGroup, and the first one with
8112 such an object is used as the LDAP base. For Kerberos, a similar
8113 search is done by first looking for a host named kerberos, and then
8114 for the _kerberos._tcp SRV record. I
've been unable to find a way to
8115 look up the Kerberos realm, so for this the upper case string of the
8116 current DNS domain is used.
</p
>
8118 <p
>For the syslog server, the hosts syslog and loghost are searched
8119 for, and the _syslog._udp SRV record is consulted if no such host is
8120 found. This algorithm works for both Debian Edu and the University of
8121 Oslo. A similar strategy would work for locating the sitesummary
8122 server, but have not been implemented yet. I decided to fetch and
8123 save these settings during installation, to make sure moving to a
8124 different network does not change the set of users being allowed to
8125 log in nor the passwords required to log in. Usernames and passwords
8126 will be cached by sssd when the user logs in on the Debian Edu
8127 network, and will not change as the laptop move around. For a
8128 non-roaming machine, there is no caching, but given that it is
8129 supposed to stay in place it should not matter much. Perhaps we
8130 should switch those to use sssd too?
</p
>
8132 <p
>The user
's SMB mount point for the network home directory is
8133 located when the user logs in for the first time. The LDAP server is
8134 consulted to look for the user
's LDAP object and the sambaHomePath
8135 attribute is used if found. If it isn
't found, the home directory
8136 path fetched from NSS is used instead. Assuming the path is of the
8137 form /site/server/directory/username, the second part is looked up in
8138 DNS and used to generate a SMB URL of the form
8139 smb://server.domain/username. This algorithm works for both Debian
8140 edu and the University of Oslo. Perhaps there are better attributes
8141 to use or a better algorithm that works for more sites, but this will
8142 do for now. :)
</p
>
8144 <p
>This work should make it easier to integrate the Debian Edu clients
8145 into any LDAP/Kerberos infrastructure, and make the current setup even
8146 more flexible than before. I suspect it will also work for thin
8147 client servers, allowing one to easily set up LTSP and hook it into a
8148 existing network infrastructure, but I have not had time to test this
8151 <p
>If you want to help out with implementing these things for Debian
8152 Edu, please contact us on debian-edu@lists.debian.org.
</p
>
8154 <p
>Update
2010-
08-
09: Simon Farnsworth gave me a heads-up on how to
8155 detect Kerberos realm from DNS, by looking for _kerberos TXT entries
8156 before falling back to the upper case DNS domain name. Will have to
8157 implement it for Debian Edu. :)

8166 <description><p
>A few years ago, I was involved in a project planning to use
8167 Windows file servers as home directory servers for Debian
8168 Edu/Skolelinux machines. This was thought to be no problem, as the
8169 access would be through the SMB network file system protocol, and we
8170 knew other sites used SMB with unix and samba as the file server to
8171 mount home directories without any problems. But, after months of
8172 struggling, we had to conclude that our goal was impossible.
</p
>
8174 <p
>The reason is simply that while SMB can be used for home
8175 directories when the file server is Samba running on Unix, this only
8176 work because of Samba have some extensions and the fact that the
8177 underlying file system is a unix file system. When using a Windows
8178 file server, the underlying file system do not have POSIX semantics,
8179 and several programs will fail if the users home directory where they
8180 want to store their configuration lack POSIX semantics.
</p
>
8182 <p
>As part of this work, I wrote a small C program I want to share
8183 with you all, to replicate a few of the problematic applications (like
8184 OpenOffice.org and GCompris) and see if the file system was working as
8185 it should. If you find yourself in spooky file system land, it might

>A few days ago, I
8398 <a href=
"http://people.skolelinux.org/pere/blog/Debian_Edu_roaming_workstation___at_the_university_of_Oslo.html
">tried
8399 to install
</a
> a Roaming workation profile from Debian Edu/Squeeze
8400 while on the university network here at the University of Oslo, and
8401 noticed how much had to change to get it operational using the
8402 university infrastructure. It was fairly easy, but it occured to me
8403 that Debian Edu would improve a lot if I could get the client to
8404 connect without any changes at all, and thus let the client configure
8405 itself during installation and first boot to use the infrastructure
8406 around it. Now I am a huge step further along that road.
</p
>
8408 <p
>With our current squeeze-test packages, I can select the roaming
8409 workstation profile and get a working laptop connecting to the
8410 university LDAP server for user and group and our active directory
8411 servers for Kerberos authentication. All this without any
8412 configuration at all during installation. My users home directory got
8413 a bookmark in the KDE menu to mount it via SMB, with the correct URL.
8414 In short, openldap and sssd is correctly configured. In addition to
8415 this, the client look for http://wpad/wpad.dat to configure a web
8416 proxy, and when it fail to find it no proxy settings are stored in
8417 /etc/environment and /etc/apt/apt.conf. Iceweasel and KDE is
8418 configured to look for the same wpad configuration and also do not use
8419 a proxy when at the university network. If the machine is moved to a
8420 network with such wpad setup, it would automatically use it when DHCP
8421 gave it a IP address.
</p
>
8423 <p
>The LDAP server is located using DNS, by first looking for the DNS
8424 entry ldap.$domain. If this do not exist, it look for the
8425 _ldap._tcp.$domain SRV records and use the first one as the LDAP
8426 server. Next, it connects to the LDAP server and search all
8427 namingContexts entries for posixAccount or posixGroup objects, and
8428 pick the first one as the LDAP base. For Kerberos, a similar
8429 algorithm is used to locate the LDAP server, and the realm is the
8430 uppercase version of $domain.
</p
>
8432 <p
>So, what is not working, you might ask. SMB mounting my home
8433 directory do not work. No idea why, but suspected the incorrect
8434 Kerberos settings in /etc/krb5.conf and /etc/samba/smb.conf might be
8435 the cause. These are not properly configured during installation, and
8436 had to be hand-edited to get the correct Kerberos realm and server,
8437 but SMB mounting still do not work. :(
</p
>
8439 <p
>With this automatic configuration in place, I expect a Debian Edu
8440 roaming profile installation would be able to automatically detect and
8441 connect to any site using LDAP and Kerberos for NSS directory and PAM
8442 authentication. It should also work out of the box in a Active
8443 Directory environment providing posixAccount and posixGroup objects
8444 with UID and GID values.

>The new roaming workstation profile in Debian Edu/Squeeze is fairly
8457 similar to the laptop setup am I working on using Ubuntu for the
8458 University of Oslo, and just for the heck of it, I tested today how
8459 hard it would be to integrate that profile into the university
8460 infrastructure. In this case, it is the university LDAP server,
8461 Active Directory Kerberos server and SMB mounting from the Netapp file
8464 <p
>I was pleasantly surprised that the only three files needed to be
8465 changed (/etc/sssd/sssd.conf, /etc/ldap.conf and
8466 /etc/mklocaluser.d/
20-debian-edu-config) and one file had to be added
8467 (/usr/share/perl5/Debian/Edu_Local.pm), to get the client working.
8468 Most of the changes were to get the client to use the university LDAP
8469 for NSS and Kerberos server for PAM, but one was to change a hard
8470 coded DNS domain name in the mklocaluser hook from .intern to
8473 <p
>This testing was so encouraging, that I went ahead and adjusted the
8474 Debian Edu scripts and setup in subversion to centralise the roaming
8475 workstation setup a bit more and avoid the hardcoded DNS domain name,
8476 so that when I test this tomorrow, I expect to get away with modifying
8477 only /etc/sssd/sssd.conf and /etc/ldap.conf to get it to use the
8478 university servers.
</p
>
8480 <p
>My goal is to get the clients to have no hardcoded settings and
8481 fetch all their initial setup during installation and first boot, to
8482 allow them to be inserted also into environments where the default
8483 setup in Debian Edu has been changed or as with the university, where

>The last few months me and the other Debian Edu developers have
8614 been working hard to get the Debian/Squeeze based version of Debian
8615 Edu/Skolelinux into shape. This future version will use Kerberos for
8616 authentication, and services are slowly migrated to single signon,
8617 getting rid of password questions one at the time.
</p
>
8619 <p
>It will also feature a roaming workstation profile with local home
8620 directory, for laptops that are only some times on the Skolelinux
8621 network, and for this profile a shortcut is created in Gnome and KDE
8622 to gain access to the users home directory on the file server. This
8623 shortcut uses SMB at the moment, and yesterday I had time to test if
8624 SMB mounting had started working in KDE after we added the cifs-utils
8625 package. I was pleasantly surprised how well it worked.
</p
>
8627 <p
>Thanks to the recent changes to our samba configuration to get it
8628 to use Kerberos for authentication, there were no question about user
8629 password when mounting the SMB volume. A simple click on the shortcut
8630 in the KDE menu, and a window with the home directory popped
8633 <p
>One step closer to a single signon solution out of the box in
8634 Debian Edu. We already had PAM, LDAP, IMAP and SMTP in place, and now
8635 also Samba. Next step is Cups and hopefully also NFS.
</p

8637 <p
>We had planned a alpha0 release of Debian Edu for today, but thanks
8638 to the autobuilder administrators for some architectures being slow to
8639 sign packages, we are still missing the fixed LTSP package we need for
8640 the release. It was uploaded three days ago with urgency=high, and if
8641 it had entered testing yesterday we would have been able to test it in
8642 time for a alpha0 release today. As the binaries for ia64 and powerpc
8643 still not uploaded to the Debian archive, we need to delay the alpha
8644 release another day.

8905 the DN pointed to by the dhcpServer entries. The latter should make

8975 <description><p
>For a while now, I have wanted to find a way to change the DNS and
8976 DHCP services in Debian Edu to use the same LDAP objects for a given
8977 computer, to avoid the possibility of having a inconsistent state for
8978 a computer in LDAP (as in DHCP but no DNS entry or the other way
8979 around) and make it easier to add computers to LDAP.
</p
>
8981 <p
>I
've looked at how powerdns and dhcpd is using LDAP, and using this
8982 information finally found a solution that seem to work.
</p
>
8984 <p
>The old setup required three LDAP objects for a given computer.
8985 One forward DNS entry, one reverse DNS entry and one DHCP entry. If
8986 we switch powerdns to use its strict LDAP method (ldap-method=strict
8987 in pdns-debian-edu.conf), the forward and reverse DNS entries are
8988 merged into one while making it impossible to transfer the reverse map
8989 to a slave DNS server.
</p
>
8991 <p
>If we also replace the object class used to get the DNS related
8992 attributes to one allowing these attributes to be combined with the
8993 dhcphost object class, we can merge the DNS and DHCP entries into one.
8994 I
've written such object class in the dnsdomainaux.schema file (need
8995 proper OIDs, but that is a minor issue), and tested the setup. It
8996 seem to work.
</p
>
8998 <p
>With this test setup in place, we can get away with one LDAP object
8999 for both DNS and DHCP, and even the LTSP configuration I suggested in
9000 an earlier email. The combined LDAP object will look something like

9018 before asking DNS to resolve the fixed-adddress. LTSP will use
9019 dhcphwaddress or associateddomain and the ldapconfig* attributes.
</p
>
9021 <p
>I am not yet sure if I can get the DHCP server to look for its
9022 dhcphost in a different location, to allow us to put the objects
9023 outside the
"DHCP Config
" subtree, but hope to figure out a way to do
9024 that. If I can
't figure out a way to do that, we can still get rid of
9025 the hosts subtree and move all its content into the DHCP Config tree
9026 (which probably should be renamed to be more related to the new
9027 content. I suspect cn=dnsdhcp,ou=services or something like that
9028 might be a good place to put it.

9041 sourcing files from /usr/share/ltsp/ltsp_config.d/ on the thin

9043 Debian Edu choose to store configuration there.
</p

9045 <p

9046 to get configuration from LDAP. The idea is to look up the MAC

9244 <description><p
>For a laptop, centralized user directories and password checking is
9245 a bit troubling. Laptops are typically used also when not connected
9246 to the network, and it is vital for a user to be able to log in or
9247 unlock the screen saver also when a central server is unavailable.
9248 This is possible by caching passwords and directory information (user
9249 and group attributes) locally, and the packages to do so are available
9250 in Debian. Here follow two recipes to set this up in Debian/Squeeze.
9251 It is also possible to set up in Debian/Lenny, but require more manual
9252 setup there because pam-auth-update is missing in Lenny.
</p
>
9254 <h2
>LDAP/Kerberos + nscd + libpam-ccreds + libpam-mklocaluser/pam_mkhomedir
</h2
>
9256 This is the traditional method with a twist. The password caching is
9257 provided by libpam-ccreds (version
10-
4 or later is needed on
9258 Squeeze), and the directory caching is done by nscd. The directory
9259 lookup and password checking is done using LDAP. If one want to use
9260 Kerberos for password checking the libpam-ldapd package can be
9261 replaced with libpam-krb5 or libpam-heimdal. If one is happy having a
9262 local home directory with the path listed in LDAP, one can use the
9263 pam_mkhomedir module from pam-modules to make this happen instead of
9264 using libpam-mklocaluser. A setup for pam-auth-update to enable
9265 pam_mkhomedir will have to be written until a fix for
9266 <a href=
"http://bugs.debian.org/
568577">bug #
568577</a
> is in the
9267 archive. Because I believe it is a bad idea to have local home
9268 directories using misleading paths like /site/server/partition/, I
9269 prefer to create a local user with the home directory in /home/. This
9270 is done using the libpam-mklocaluser package.

9281 sent in clear text to the LDAP server. I
've been unable to get TLS
9282 certificate checking for a self signed certificate working, which make
9283 LDAP authentication unsafe for Debian Edu (nslcd is not checking if it
9284 is talking to the correct LDAP server), and very much welcome feedback
9285 on how to get this working.

>The last few days I have been looking into the status of the LDAP
9451 directory in Debian Edu, and in the process I started to miss a GUI
9452 tool to browse the LDAP tree. The only one I was able to find in
9453 Debian/Squeeze and Lenny is
9454 <a href=
"http://luma.sourceforge.net/
">LUMA
</a
>, which has proved to
9455 be a great tool to get a overview of the current LDAP directory
9456 populated by default in Skolelinux. Thanks to it, I have been able to
9457 find empty and obsolete subtrees, misplaced objects and duplicate
9458 objects. It will be installed by default in Debian/Squeeze. If you
9459 are working with LDAP, give it a go. :)
</p
>
9461 <p
>I did notice one problem with it I have not had time to report to
9462 the BTS yet. There is no .desktop file in the package, so the tool do
9463 not show up in the Gnome and KDE menus, but only deep down in in the
9464 Debian submenu in KDE. I hope that can be fixed before Squeeze is
9467 <p
>I have not yet been able to get it to modify the tree yet. I would
9468 like to move objects and remove subtrees directly in the GUI, but have
9469 not found a way to do that with LUMA yet. So in the mean time, I use
9470 <a href=

29: Ross Reedstrom tipped us about the
9476 <a href=
"http://packages.qa.debian.org/g/gq.html
">gq
</a
> package as a
9477 useful GUI alternative. It seem like a good tool, but is unmaintained
9478 in Debian and got a RC bug keeping it out of Squeeze. Unless that
9479 changes, it will not be an option for Debian Edu based on Squeeze.

9543 I am now testing dist-upgrade of Gnome and KDE in a chroot using both
9544 apt and aptitude, and found their differences interesting. This time
9545 I will only focus on their removal plans.
</p
>
9547 <p
>After installing a Gnome desktop and the laptop task, apt-get wants
9548 to remove
72 packages when dist-upgrading from Lenny to Squeeze. The
9549 surprising part is that it want to remove xorg and all
9550 xserver-xorg-video* drivers. Clearly not a good choice, but I am not
9551 sure why. When asking aptitude to do the same, it want to remove
129
9552 packages, but most of them are library packages I suspect are no
9553 longer needed. Both of them want to remove bluetooth packages, which
9554 I do not know. Perhaps these bluetooth packages are obsolete?
</p
>
9556 <p
>For KDE, apt-get want to remove
82 packages, among them kdebase
9557 which seem like a bad idea and xorg the same way as with Gnome. Asking
9558 aptitude for the same, it wants to remove
192 packages, none which are
9559 too surprising.
</p
>
9561 <p
>I guess the removal of xorg during upgrades should be investigated
9562 and avoided, and perhaps others as well. Here are the complete list
9563 of planned removals. The complete logs is available from the URL
9564 above. Note if you want to repeat these tests, that the upgrade test
9565 for kde+apt-get hung in the tasksel setup because of dpkg asking
9566 conffile questions. No idea why. I worked around it by using

9714 <description><p
>The last few days I have done some upgrade testing in Debian, to
9715 see if the upgrade from Lenny to Squeeze will go smoothly. A few bugs
9716 have been discovered and reported in the process
9717 (
<a href=
"http://bugs.debian.org/
585410">#
585410</a
> in nagios3-cgi,
9718 <a href=
"http://bugs.debian.org/
584879">#
584879</a
> already fixed in
9719 enscript and
<a href=
"http://bugs.debian.org/
584861">#
584861</a
> in
9720 kdebase-workspace-data), and to get a more regular testing going on, I
9721 am working on a script to automate the test.
</p
>
9723 <p
>The idea is to create a Lenny chroot and use tasksel to install a
9724 Gnome or KDE desktop installation inside the chroot before upgrading
9725 it. To ensure no services are started in the chroot, a policy-rc.d
9726 script is inserted. To make sure tasksel believe it is to install a
9727 desktop on a laptop, the tasksel tests are replaced in the chroot
9728 (only acceptable because this is a throw-away chroot).
</p
>
9730 <p
>A naive upgrade from Lenny to Squeeze using aptitude dist-upgrade
9731 currently always fail because udev refuses to upgrade with the kernel
9732 in Lenny, so to avoid that problem the file /etc/udev/kernel-upgrade
9733 is created. The bug report
9734 <a href=
"http://bugs.debian.org/
566000">#
566000</a
> make me suspect
9735 this problem do not trigger in a chroot, but I touch the file anyway
9736 to make sure the upgrade go well. Testing on virtual and real
9737 hardware have failed me because of udev so far, and creating this file
9738 do the trick in such settings anyway. This is a
9739 <a href=
"http://www.linuxquestions.org/questions/debian-
26/failed-dist-upgrade-due-to-udev-config_sysfs_deprecated-nonsense-
804130/
">known
9740 issue
</a
> and the current udev behaviour is intended by the udev
9741 maintainer because he lack the resources to rewrite udev to keep
9742 working with old kernels or something like that. I really wish the
9743 udev upstream would keep udev backwards compatible, to avoid such
9744 upgrade problem, but given that they fail to do so, I guess
9745 documenting the way out of this mess is the best option we got for
9746 Debian Squeeze.
</p

9749 script, which I call

>Som systemarkitekten bak Skolelinux, kan jeg bare riste på hodet
9872 over påstanden om at Skolelinux krever desentraliserte tjenere.
9873 Skolelinux-arkitekturen er laget for sentralisert drift og plassering
9874 av tjenerne lokalt eller sentralt alt etter behov og nettkapasitet.
9875 Den er modellert på nettverks- og tjenerløsningen som brukes på
9876 Universitetet i Tromsø og Oslo, der jeg jobber med utvikling av
9877 driftstjenester. Dette er det heldigvis noen som har fått med seg, og
9878 jeg er glad for å kunne sitere fra en kommentar på den overnevnte
9879 artikkelen. Min venn og gamle kollega Sturle Sunde forteller der:
9882 <p
>I Flora kommune køyrer vi Skulelinux på skular med alt frå
15 til
9883 meir enn
500 elevar. Dei store skulane har eigen tenar, for det er
9884 mest praktisk. Eg, som er driftsansvarleg for heile nettet, ser
9885 sjeldan dei tenarane fysisk, men at dei står der gjer skulane mindre
9886 avhengige av eksterne linjer som er trege eller dyre. Dei minste
9887 skulane har ikkje eigen tenar. Å bruke sentral tenar er heller ikkje
9888 noko problem. Småskulane klarar seg fint med
1 mbit-linje til ein
9889 sentral tenar eller tenaren på ein større skule.
</p
>
9891 <p
>Det beste med Skulelinux er halvtjukke klientar. Dei treng ikkje
9892 harddisk og brukar minimalt med ressursar på tenaren fordi dei køyrer
9893 programma lokalt. Eit klasserom med
30 sju-åtte år gamle maskiner har
9894 mykje meir CPU og RAM totalt enn nokon moderne tenar til under
9895 millionen. Det trengst to kommandoar på den sentrale tenaren for å
9896 oppdatere alle klientane, både tynne og halvtjukke. Vi har ingen
9897 problem med diskar som ryk heller, som var eit problem før fordi
9898 elevane sat og sparka i maskinene. Og dei krev lite bandbreidde i
9899 nettet, so det er fullt mogleg å køyre slike på småskular med trege
9900 linjer mot tenaren på ein større skule.
</p
>
9902 <p
>Flora kommune har nesten
800 Linux-maskiner i sitt skulenett, og
9903 ein person som tek seg av drift av heile nettet, inkludert tenarar,
9904 klientar, operativsystem, programvare, heimekontorløysing og
9905 administrasjon av brukarar.
</p
>
9907 <p
>No skal det seiast at vi ikkje køyrer rein Skulelinux ut av
9908 boksen. Vi har gjort ein del tilpassingar mot noko Novell-greier som
9909 var der frå før, og som har komplisert installasjonen vår. Etter at
9910 oppsettet var gjort har løysinga vore stabil og kravd minimalt med
9914 <p
>Jeg vet at Narvik, Harstad og Oslo er kommuner der Skolelinux
9915 sentraldriftes med sentrale tjenere. Det forteller meg at Steinkjers
9916 IT-sjef neppe bør skylde på Skolelinux-løsningen for sine
5 år gamle

9996 maintainers expect kdm to be set up to wait longer, while kdm expect
9997 the nvidia driver maintainers to fix the driver to start faster, and
9998 while they wait for each other I guess the users end up switching to a

>A few days ago, parallel booting was enabled in Debian/testing.
10012 The feature seem to hold up pretty well, but three fairly serious
10013 issues are known and should be solved:
10015 <p

10017 <li
>The wicd package seen to
10018 <a href=

10019 <a href=

581586">network setup
</a
> when
10020 parallel booting is enabled. No idea why, but the wicd maintainer
10021 seem to be on the case.
</li

10023 <li
>The nvidia X driver seem to
10024 <a href=
"http://bugs.debian.org/
583312">have a race condition
</a

10025 triggered more easily when parallel booting is in effect. The
10026 maintainer is on the case.
</li
>
10028 <li
>The sysv-rc package fail to properly enable dependency based boot
10029 sequencing (the shutdown is broken) when old file-rc users
10030 <a href=
"http://bugs.debian.org/
575080">try to switch back

10031 sysv-rc. One way to solve it would be for file-rc to create
10032 /etc/init.d/.legacy-bootordering, and another is to try to make
10033 sysv-rc more robust. Will investigate some more and probably upload a
10034 workaround in sysv-rc to help those trying to move from file-rc to
10035 sysv-rc get a working shutdown.

>After a long break from debian-installer development, I finally
10059 found time today to return to the project. Having to spend less time
10060 working dependency based boot in debian, as it is almost complete now,
10061 definitely helped freeing some time.
</p
>
10063 <p
>A while back, I ran into a problem while working on Debian Edu. We
10064 include some firmware packages on the Debian Edu CDs, those needed to
10065 get disk and network controllers working. Without having these
10066 firmware packages available during installation, it is impossible to
10067 install Debian Edu on the given machine, and because our target group
10068 are non-technical people, asking them to provide firmware packages on
10069 an external medium is a support pain. Initially, I expected it to be
10070 enough to include the firmware packages on the CD to get
10071 debian-installer to find and use them. This proved to be wrong.
10072 Next, I hoped it was enough to symlink the relevant firmware packages
10073 to some useful location on the CD (tried /cdrom/ and
10074 /cdrom/firmware/). This also proved to not work, and at this point I
10075 found time to look at the debian-installer code to figure out what was
10076 going to work.
</p
>
10078 <p
>The firmware loading code is in the hw-detect package, and a closer
10079 look revealed that it would only look for firmware packages outside
10080 the installation media, so the CD was never checked for firmware
10081 packages. It would only check USB sticks, floppies and other
10082 "external
" media devices. Today I changed it to also look in the
10083 /cdrom/firmware/ directory on the mounted CD or DVD, which should
10084 solve the problem I ran into with Debian edu. I also changed it to
10085 look in /firmware/, to make sure the installer also find firmware
10086 provided in the initrd when booting the installer via PXE, to allow us
10087 to provide the same feature in the PXE setup included in Debian
10090 <p
>To make sure firmware deb packages with a license questions are not
10091 activated without asking if the license is accepted, I extended
10092 hw-detect to look for preinst scripts in the firmware packages, and
10093 run these before activating the firmware during installation. The
10094 license question is asked using debconf in the preinst, so this should
10095 solve the issue for the firmware packages I have looked at so far.

>Today, the last piece of the puzzle for roaming laptops in Debian
10108 Edu finally entered the Debian archive. Today, the new
10109 <a href=
"http://packages.qa.debian.org/libp/libpam-mklocaluser.html
">libpam-mklocaluser
</a
>
10110 package was accepted. Two days ago, two other pieces was accepted
10112 <a href=
"http://packages.qa.debian.org/p/pam-python.html
">pam-python
</a

10113 package needed by libpam-mklocaluser, and the
10114 <a href=
"http://packages.qa.debian.org/s/sssd.html
">sssd
</a
> package
10115 passed NEW on Monday. In addition, the
10116 <a href=
"http://packages.qa.debian.org/libp/libpam-ccreds.html
">libpam-ccreds
</a
>
10117 package we need is in experimental (version
10-
4) since Saturday, and
10118 hopefully will be moved to unstable soon.
</p
>
10120 <p
>This collection of packages allow for two different setups for
10121 roaming laptops. The traditional setup would be using libpam-ccreds,
10122 nscd and libpam-mklocaluser with LDAP or Kerberos authentication,
10123 which should work out of the box if the configuration changes proposed
10124 for nscd in
<a href=
"http://bugs.debian.org/
485282">BTS report
10125 #
485282</a
> is implemented. The alternative setup is to use sssd with
10126 libpam-mklocaluser to connect to LDAP or Kerberos and let sssd take
10127 care of the caching of passwords and group information.
</p
>
10129 <p
>I have so far been unable to get sssd to work with the LDAP server
10130 at the University, but suspect the issue is some SSL/GnuTLS related
10131 problem with the server certificate. I plan to update the Debian
10132 package to version
1.2, which is scheduled for next week, and hope to
10133 find time to make sure the next release will include both the
10134 Debian/Ubuntu specific patches. Upstream is friendly and responsive,
10135 and I am sure we will find a good solution.
</p
>
10137 <p
>The idea is to set up the roaming laptops to authenticate using
10138 LDAP or Kerberos and create a local user with home directory in /home/
10139 when a usre in LDAP logs in via KDM or GDM for the first time, and
10140 cache the password for offline checking, as well as caching group
10141 memberhips and other relevant LDAP information. The
10142 libpam-mklocaluser package was created to make sure the local home
10143 directory is in /home/, instead of /site/server/directory/ which would
10144 be the home directory if pam_mkhomedir was used. To avoid confusion
10145 with support requests and configuration, we do not want local laptops
10146 to have users in a path that is used for the same users home directory
10147 on the home directory servers.
</p
>
10149 <p
>One annoying problem with gdm is that it do not show the PAM
10150 message passed to the user from libpam-mklocaluser when the local user
10151 is created. Instead gdm simply reject the login with some generic
10152 message. The message is shown in kdm, ssh and login, so I guess it is
10153 a bug in gdm. Have not investigated if there is some other message
10154 type that can be used instead to get gdm to also show the message.

>For some years now, I have wondered how we should handle laptops in
10312 Debian Edu. The Debian Edu infrastructure is mostly designed to
10313 handle stationary computers, and less suited for computers that come
10316 <p
>Now I finally believe I have an sensible idea on how to adjust
10317 Debian Edu for laptops, by introducing a new profile for them, for
10318 example called Roaming Workstations. Here are my thought on this.
10319 The setup would consist of the following:
</p
>
10323 <li
>During installation, the user name of the owner / primary user of
10324 the laptop is requested and a local home directory is set up for
10325 the user, with uid and gid information fetched from the LDAP
10326 server. This allow the user to work also when offline. The
10327 central home directory can be available in a subdirectory on
10328 request, for example mounted via CIFS. It could be mounted
10329 automatically when a user log in while on the Debian Edu network,
10330 and unmounted when the machine is taken away (network down,
10331 hibernate, etc), it can be set up to do automatic mounting on
10332 request (using autofs), or perhaps some GUI button on the desktop
10333 can be used to access it when needed. Perhaps it is enough to use
10334 the fish protocol in KDE?
</li
>
10336 <li
>Password checking is set up to use LDAP or Kerberos
10337 authentication when the machine is on the Debian Edu network, and
10338 to cache the password for offline checking when the machine unable
10339 to reach the LDAP or Kerberos server. This can be done using
10340 <a href=
"http://www.padl.com/OSS/pam_ccreds.html
">libpam-ccreds
</a
>
10341 or the Fedora developed
10342 <a href=
"https://fedoraproject.org/wiki/Features/SSSD
">System
10343 Security Services Daemon
</a
> packages.
</li
>
10345 <li
>File synchronisation with the central home directory is set up
10346 using a shared directory in both the local and the central home
10347 directory, using unison.
</li
>
10349 <li
>Printing should be set up to print to all printers broadcasting
10350 their existence on the local network, and should then work out of
10351 the box with CUPS. For sites needing accurate printer quotas, some
10352 system with Kerberos authentication or printing via ssh could be
10353 implemented.
</li
>
10355 <li
>For users that should have local root access to their laptop,
10356 sudo should be used to allow this to the local user.
</li
>
10358 <li
>It would be nice if user and group information from LDAP is
10359 cached on the client, but given that there are entries for the
10360 local user and primary group in /etc/, it should not be needed.

10369 perhaps debian-edu-config) should get some integration code to stop
10370 its daemon when the LDAP server is unavailable to avoid long timeouts
10371 when disconnected from the net. If we get Kerberos enabled, we need
10372 to make sure we avoid long timeouts there too.

10385 NUUG presentation
</a
> about Kerberos was inspiring, and reminded me
10386 about the need to start using Kerberos in Skolelinux. Setting up a
10387 Kerberos server seem to be straight forward, and if we get this in
10388 place a long time before the Squeeze version of Debian freezes, we
10389 have a chance to migrate Skolelinux away from NFSv3 for the home
10390 directories, and over to an architecture where the infrastructure do
10391 not have to trust IP addresses and machines, and instead can trust
10392 users and cryptographic keys instead.
</p
>
10394 <p
>A challenge will be integration and administration. Is there a
10395 Kerberos implementation for Debian where one can control the
10396 administration access in Kerberos using LDAP groups? With it, the
10397 school administration will have to maintain access control using flat
10398 files on the main server, which give a huge potential for errors.
</p
>
10400 <p
>A related question I would like to know is how well Kerberos and
10401 pam-ccreds (offline password check) work together. Anyone know?
</p
>
10403 <p
>Next step will be to use Kerberos for access control in Lwat and
10404 Nagios. I have no idea how much work that will be to implement. We
10405 would also need to document how to integrate with Windows AD, as such
10406 shared network will require two Kerberos realms that need to cooperate
10407 to work properly.
</p
>
10409 <p
>I believe a good start would be to start using Kerberos on the
10410 skolelinux.no machines, and this way get ourselves experience with
10411 configuration and integration. A natural starting point would be
10412 setting up ldap.skolelinux.no as the Kerberos server, and migrate the
10413 rest of the machines from PAM via LDAP to PAM via Kerberos one at the
10416 <p
>If you would like to contribute to get this working in Skolelinux,
10417 I recommend you to see the video recording from yesterdays NUUG
10418 presentation, and start using Kerberos at home. The video show show
10419 up in a few days.

>6 years ago, as part of the Debian Edu development I am involved
10429 in, I asked for a hook in the kdm and gdm setup to run scripts as root
10430 when the user log out. A bug was submitted against the xfree86-common
10431 package in
2004 (
<a href=
"http://bugs.debian.org/
230422">#
230422</a

10432 and revisited every time Debian Edu was working on a new release.
10433 Today, this finally paid off.
</p
>
10435 <p
>The framework for this feature was today commited to the git
10436 repositry for the xorg package, and the git repository for xdm has
10437 been updated to use this framework. Next on my agenda is to make sure
10438 kdm and gdm also add code to use this framework.
</p
>
10440 <p
>In Debian Edu, we want to ability to run commands as root when the
10441 user log out, to get rid of runaway processes and do general cleanup
10442 after a user. With this framework in place, we finally can do that in
10443 a generic way that work with all display managers using this
10444 framework. My goal is to get all display managers in Debian use it,
10445 similar to how they use the Xsession.d framework today.

>One of the new features in the next Debian/Lenny based release of
10477 Debian Edu/Skolelinux, which is scheduled for release in the next few
10478 days, is automatic configuration of the service monitoring system
10479 Nagios. The previous release had automatic configuration of trend
10480 analysis using Munin, and this Lenny based release take that a step
10483 <p
>When installing a Debian Edu Main-server, it is automatically
10484 configured as a Munin and Nagios server. In addition, it is
10485 configured to be a server for the
10486 <a href=
"http://wiki.debian.org/DebianEdu/HowTo/SiteSummary
">SiteSummary
10487 system
</a
> I have written for use in Debian Edu. The SiteSummary
10488 system is inspired by a system used by the University of Oslo where I
10489 work. In short, the system provide a centralised collector of
10490 information about the computers on the network, and a client on each
10491 computer submitting information to this collector. This allow for
10492 automatic information on which packages are installed on each machine,
10493 which kernel the machines are using, what kind of configuration the
10494 packages got etc. This also allow us to automatically generate Munin
10495 and Nagios configuration.
</p
>
10497 <p
>All computers reporting to the sitesummary collector with the
10498 munin-node package installed is automatically enabled as a Munin
10499 client and graphs from the statistics collected from that machine show
10500 up automatically on http://www/munin/ on the Main-server.
</p
>
10502 <p
>All non-laptop computers reporting to the sitesummary collector are
10503 automatically monitored for network presence (ping and any network
10504 services detected). In addition, all computers (also laptops) with
10505 the nagios-nrpe-server package installed and configured the way
10506 sitesummary would configure it, are monitored for full disks, software
10507 raid status, swap free and other checks that need to run locally on
10508 the machine.
</p
>
10510 <p
>The result is that the administrator on a school using Debian Edu
10511 based on Lenny will be able to check the health of his installation
10512 with one look at the Nagios settings, without having to spend any time
10513 keeping the Nagios configuration up-to-date.
</p
>
10515 <p
>The only configuration one need to do to get Nagios up and running
10516 is to set the password used to get access via HTTP. The system
10517 administrator need to run
"<tt
>htpasswd /etc/nagios3/htpasswd.users
10518 nagiosadmin
</tt
>" to create a nagiosadmin user and set a password for
10519 it to be able to log into the Nagios web pages. After that,
10520 everything is taken care of.

10590 Edu/Skolelinux development gathering. I got a bit done tuning the
10591 desktop, and looked into the dynamic service location protocol
10592 implementation avahi. It look like it could be useful for us. Almost
10593 30 people participated, and I believe it was a great environment to
10594 get to know the Skolelinux system. Walter Bender, involved in the
10595 development of the Sugar educational platform, presented his stuff and
10596 also helped me improve my OLPC installation. He also showed me that
10597 his Turtle Art application can be used in standalone mode, and we
10598 agreed that I would help getting it packaged for Debian. As a
10599 standalone application it would be great for Debian Edu. We also
10600 tried to get the video conferencing working with two OLPCs, but that
10601 proved to be too hard for us. The application seem to need more work

10713 the Brazilian group, so that will have to wait for the next
10714 development gathering. Would love to have the Debian Edu installer
10715 automatically detect and configure a multiseat setup when it find one
10716 of these cards.

>Recently I have spent some time evaluating the multimedia browser
10726 plugins available in Debian Lenny, to see which one we should use by
10727 default in Debian Edu. We need an embedded video playing plugin with
10728 control buttons to pause or stop the video, and capable of streaming
10729 all the multimedia content available on the web. The test results and
10730 notes are available on
10731 <a href=
"http://wiki.debian.org/DebianEdu/BrowserMultimedia
">the
10732 Debian wiki
</a
>. I was surprised how few of the plugins are able to
10733 fill this need. My personal video player favorite, VLC, has a really
10734 bad plugin which fail on a lot of the test pages. A lot of the MIME
10735 types I would expect to work with any free software player (like
10736 video/ogg), just do not work. And simple formats like the
10737 audio/x-mplegurl format (m3u playlists), just isn
't supported by the
10738 totem and vlc plugins. I hope the situation will improve soon. No
10739 wonder sites use the proprietary Adobe flash to play video.
