>The
<a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
15 project
</a
> provide an instruction manual for teachers, system
16 administrators and other users that contain useful tips for setting up
17 and maintaining a Debian Edu installation. This text is about how the
18 text processing of this manual is handled in the project.
</p
>
20 <p
>One goal of the project is to provide information in the native
21 language of its users, and for this we need to handle translations.
22 But we also want to make sure each language contain the same
23 information, so for this we need a good way to keep the translations
24 in sync. And we want it to be easy for our users to improve the
25 documentation, avoiding the need to learn special formats or tools to
26 contribute, and the obvious way to do this is to make it possible to
27 edit the documentation using a web browser. We also want it to be
28 easy for translators to keep the translation up to date, and give them
29 help in figuring out what need to be translated. Here is the list of
30 tools and the process we have found trying to reach all these
33 <p
>We maintain the authoritative source of our manual in the
34 <a href=
"https://wiki.debian.org/DebianEdu/Documentation/Wheezy/
">Debian
35 wiki
</a
>, as several wiki pages written in English. It consist of one
36 front page with references to the different chapters, several pages
37 for each chapter, and finally one
"collection page
" gluing all the
38 chapters together into one large web page (aka
39 <a href=
"https://wiki.debian.org/DebianEdu/Documentation/Wheezy/AllInOne
">the
40 AllInOne page
</a
>). The AllInOne page is the one used for further
41 processing and translations. Thanks to the fact that the
42 <a href=
"http://moinmo.in/
">MoinMoin
</a
> installation on
43 wiki.debian.org support exporting pages in
44 <a href=
"http://www.docbook.org/
">the Docbook format
</a
>, we can fetch
45 the list of pages to export using the raw version of the AllInOne
46 page, loop over each of them to generate a Docbook XML version of the
47 manual. This process also download images and transform image
48 references to use the locally downloaded images. The generated
49 Docbook XML files are slightly broken, so some post-processing is done
50 using the
<tt
>documentation/scripts/get_manual
</tt
> program, and the
51 result is a nice Docbook XML file (debian-edu-wheezy-manual.xml) and
52 a handfull of images. The XML file can now be used to generate PDF, HTML
53 and epub versions of the English manual. This is the basic step of
54 our process, making PDF (using dblatex), HTML (using xsltproc) and
55 epub (using dbtoepub) version from Docbook XML, and the resulting files
56 are placed in the debian-edu-doc-en binary package.
</p
>
58 <p
>But English documentation is not enough for us. We want translated
59 documentation too, and we want to make it easy for translators to
60 track the English original. For this we use the
61 <a href=
"http://packages.qa.debian.org/p/poxml.html
">poxml
</a
> package,
62 which allow us to transform the English Docbook XML file into a
63 translation file (a .pot file), usable with the normal gettext based
64 translation tools used by those translating free software. The pot
65 file is used to create and maintain translation files (several .po
66 files), which the translations update with the native language
67 translations of all titles, paragraphs and blocks of text in the
68 original. The next step is combining the original English Docbook XML
69 and the translation file (say debian-edu-wheezy-manual.nb.po), to
70 create a translated Docbook XML file (in this case
71 debian-edu-wheezy-manual.nb.xml). This translated (or partly
72 translated, if the translation is not complete) Docbook XML file can
73 then be used like the original to create a PDF, HTML and epub version
74 of the documentation.
</p
>
76 <p
>The translators use different tools to edit the .po files. We
78 <a href=
"http://www.kde.org/applications/development/lokalize/
">lokalize
</a
>,
79 while some use emacs and vi, others can use web based editors like
80 <a href=
"http://pootle.translatehouse.org/
">Poodle
</a
> or
81 <a href=
"https://www.transifex.com/
">Transifex
</a
>. All we care about
82 is where the .po file end up, in our git repository. Updated
83 translations can either be committed directly to git, or submitted as
84 <a href=
"https://bugs.debian.org/src:debian-edu-doc
">bug reports
85 against the debian-edu-doc package
</a
>.
</p
>
87 <p
>One challenge is images, which both might need to be translated (if
88 they show translated user applications), and are needed in different
89 formats when creating PDF and HTML versions (epub is a HTML version in
90 this regard). For this we transform the original PNG images to the
91 needed density and format during build, and have a way to provide
92 translated images by storing translated versions in
93 images/$LANGUAGECODE/. I am a bit unsure about the details here. The
94 package maintainers know more.
</p
>
96 <p
>If you wonder what the result look like, we provide
97 <a href=
"http://maintainer.skolelinux.org/debian-edu-doc/
">the content
98 of the documentation packages on the web
</a
>. See for example the

102 HTML version

103 but perhaps it will be done in the future.

121 keep gaining new users. Some weeks ago, a person showed up on IRC,
122 <a href=
"irc://irc.debian.org/#debian-edu
">#debian-edu
</a
>, with a
123 wish to contribute, and I managed to get a interview with this great
124 contributor Roger Marsal to learn more about his background.
</p
>
126 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
128 <p
>My name is Roger Marsal, I
'm
27 years old (
1986 generation) and I
129 live in Barcelona, Spain. I
've got a strong business background and I
130 work as a patrimony manager and as a real estate agent. Additionally,
131 I
've co-founded a British based tech company that is nowadays on the
132 last development phase of a new social networking concept.
</p
>
134 <p
>I
'm a Linux enthusiast that started its journey with Ubuntu four years
135 ago and have recently switched to Debian seeking rock solid stability
136 and as a necessary step to gain expertise.
</p
>
138 <p
>In a nutshell, I spend my days working and learning as much as I
139 can to face both my job, entrepreneur project and feed my Linux
142 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
143 project?
</strong
></p
>
145 <p
>I discovered the
<a href=
"http://www.ltsp.org/
">LTSP
</a
> advantages
146 with
"Ubuntu
12.04 alternate install
" and after a year of use I
147 started looking for an alternative. Even though I highly value and
148 respect the Ubuntu project, I thought it was necessary for me to
149 change to a more robust and stable alternative. As far as I was using
150 Debian on my personal laptop I thought it would be fine to install
151 Debian and configure an LTSP server myself. Surprised, I discovered
152 that the Debian project also supported a kind of Edubuntu equivalent,
153 and after having some pain I obtained a Debian Edu network up and
154 running. I just loved it.
</p
>
156 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
157 Edu?
</strong
></p
>
159 <p
>I found a main advantage in that, once you know
"the tips and
160 tricks
", a new installation just works out of the box. It
's the most
161 complete alternative I
've found to create an LTSP network. All the
162 other distributions seems to be made of plastic, Debian Edu seems to
163 be made of steel.
</p
>
165 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
166 Edu?
</strong
></p
>
168 <p
>I found two main disadvantages.
</p
>
170 <p
>I
'm not an expert but I
've got notions and I had to spent a considerable
171 amount of time trying to bring up a standard network topology. I
'm quite
172 stubborn and I just worked until I did but I
'm sure many people with few
173 resources (not big schools, but academies for example) would have switched
174 or dropped.
</p
>
176 <p
>It
's amazing how such a complex system like Debian Edu has achieved
177 this out-of-the-box state. Even though tweaking without breaking gets
178 more difficult, as more factors have to be considered. This can
179 discourage many people too.
</p
>
181 <p
><strong
>Which free software do you use daily?
</strong
></p
>
183 <p
>I use Debian, Firefox, Okular, Inkscape, LibreOffice and
184 Virtualbox.
</p
>
187 <p
><strong
>Which strategy do you believe is the right one to use to
188 get schools to use free software?
</strong
></p
>
190 <p
>I don
't think there is a need for a particular strategy. The free
191 attribute in both
"freedom
" and
"no price
" meanings is what will
192 really bring free software to schools. In my experience I can think of
193 the
<a href=
"http://www.r-project.org/
">"R
" statistical language
</a
>; a
194 few years a ago was an extremely nerd tool for university people.
195 Today it
's being increasingly used to teach statistics at many
196 different level of studies. I believe free and open software will
197 increasingly gain popularity, but I
'm sure schools will be one of the
198 first scenarios where this will happen.

>On larger sites, it is useful to use a dedicated storage server for
208 storing user home directories and data. The design for handling this
209 in
<a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>, is
210 to update the automount rules in LDAP and let the automount daemon on
211 the clients take care of the rest. I was reminded about the need to
212 document this better when one of the customers of
213 <a href=
"http://www.slxdrift.no/
">Skolelinux Drift AS
</a
>, where I am
214 on the board of directors, asked about how to do this. The steps to
215 get this working are the following:
</p
>
219 <li
>Add new storage server in DNS. I use nas-server.intern as the
220 example host here.
</li
>
222 <li
>Add automoun LDAP information about this server in LDAP, to allow
223 all clients to automatically mount it on reqeust.
</li
>
225 <li
>Add the relevant entries in tjener.intern:/etc/fstab, because
226 tjener.intern do not use automount to avoid mounting loops.
</li
>
228 </ol
></p
>
230 <p
>DNS entries are added in GOsa², and not described here. Follow the
231 <a href=
"https://wiki.debian.org/DebianEdu/Documentation/Wheezy/GettingStarted
">instructions
232 in the manual
</a
> (Machine Management with GOsa² in section Getting
235 <p
>Ensure that the NFS export points on the server are exported to the
236 relevant subnets or machines:

>
239 root@tjener:~# showmount -e nas-server
240 Export list for nas-server:
243 </pre
></blockquote
></p
>
245 <p
>Here everything on the backbone network is granted access to the
246 /storage export. With NFSv3 it is slightly better to limit it to
247 netgroup membership or single IP addresses to have some limits on the
248 NFS access.
</p
>
250 <p
>The next step is to update LDAP. This can not be done using GOsa²,
251 because it lack a module for automount. Instead, use ldapvi and add
252 the required LDAP objects using an editor.

>
254 <p
><blockquote
><pre
>
255 ldapvi --ldap-conf -ZD
'(cn=admin)
' -b ou=automount,dc=skole,dc=skolelinux,dc=no
256 </pre
></blockquote
></p
>
258 <p
>When the editor show up, add the following LDAP objects at the
259 bottom of the document. The
"/
&" part in the last LDAP object is a
260 wild card matching everything the nas-server exports, removing the
261 need to list individual mount points in LDAP.
</p
>
263 <p

>
264 add cn=nas-server,ou=auto.skole,ou=automount,dc=skole,dc=skolelinux,dc=no

&
278 </pre

280 <p
>The last step to remember is to mount the relevant mount points in
281 tjener.intern by adding them to /etc/fstab, creating the mount
282 directories using mkdir and running
"mount -a
" to mount them.
</p
>
284 <p
>When this is done, your users should be able to access the files on
285 the storage server directly by just visiting the
286 /tjener/nas-server/storage/ directory using any application on any
287 workstation, LTSP client or LTSP server.

298 was able to get an interview with a newcomer in the project who showed
299 up on the IRC channel a few weeks ago to let us know about his
300 successful installation of Debian Edu Wheezy in his School. Say hello

</strong

308 <p
>I am a
23 year-old student from Germany who has spent half of his
309 life with open source. In
"real life
", I am, as already mentioned, a
310 student in the fields of Computer Science, Electrical Engineering,
311 Information Technologies and Anglistics. Due to my (only partially
312 voluntary) huge engagement in the open source world, these things are
313 a bit vacant right now however.
</p
>
315 <p
>I also have been working as a project teacher at a Gymasnium
316 (public school) for various years now. I took up that work some time
317 around
2005 when still attending that school myself and have continued
318 it until today. I also had been running the (kind of very advanced)
319 network of that school together with a team of very interested and
320 talented students in the age of
11 to
15 years, who took the chance to
321 learn a lot about open source and networking before I left the school
322 to help building another school

325 <p
>That said, one might see me as a kind of
"glue
" between school kids
326 and the elderly of teachers as well as between the open source
327 ecosystem and the (even more complex) educational ecosystem.
</p

329 <p
>When I am not busy with open source or education, I like Geocaching
330 and cycling.

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

335 <p
>I think that happened some time around
2009 when I first attended
336 <a href=
"http://www.froscon.org
">FrOSCon
</a
> and visited the project
337 booth. I think I wasn
't too interested back then because I used to
338 have an attitude of disliking software that does too much stuff on its
339 own. Maybe I was too inexperienced to realise the upsides of an
340 "out-of-the-box
" solution ;).
</p
>
342 <p
>The first time I actively talked to Skolelinux people was at
343 <a href=
"http://www.openrheinruhr.de
">OpenRheinRuhr
</a
> 2011 when the
344 BiscuIT project, a home-grewn software used by my school for various
345 really cool things from timetables and class contact lists to lunch
346 ordering, student ID card printing and project elections first got to
347 a stage where it could have been published. I asked the Skolelinux
348 guys running the booth if the project were interested in it and gave a
349 small demonstration, but there wasn
't any real feedback and the guys
350 seemed rather uninterested.
</p
>
352 <p
>After I left the school where I developed the software, it got
353 mostly lost, but I am now reimplementing it for my new school. I have
354 reusability and compatibility in mind, and I hop there will be a new
355 basis for contributing it to the Skolelinux project ;)!
</p
>
357 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
358 Edu?
</strong
></p
>
360 <p
>The most important advantage seems to be that it
"just
361 works
". After overcoming some minor (but still very annoying) glitches
362 in the installer, I got a fully functional, working school network,
363 without the month-long hassle I experienced when setting all that up
364 from scratch in earlier years. And above that, it rocked - I didn
't
365 have any real hardware at hand, because the school was just founded
366 and has no money whatsoever, so I installed a combined server (main
367 server, terminal services and workstation) in a VM on my personal
368 notebook, bridging the LTSP network interface to the ethernet port,
369 and then PXE-booted the Windows notebooks that were lying around from
370 it. I could use
8 clients without any performance issues, by using a
371 tiny little VM on a tiny little notebook. I think that
's enough to say
372 that it rocks!
</p
>
374 <p
>Secondly, there are marketing reasons. Life
's bad, and so no
375 politician will ever permit a setup described as
"Debian, an universal
376 operating system, with some really cool educational tools
" while they
377 will be jsut fine with
"Skolelinux, a single-purpose solution for your
378 school network
", even if both turn out to be the very same thing (yes,
379 this is unfair towards the Skolelinux project, and must not be taken
380 too seriously - you get the idea, anyway).

383 Edu?
</strong
></p

385 <p
>I have not been involved with Skolelinux long enough to really
386 answer this question in a fair way. Thus, please allow me to put it in
387 other words:
"What do you expect from Skolelinux to keep liking it?
" I
388 can list a few points about that:
</p

392 <li
>always strive to get all things integrated into Debian upstream
393 <li

"http://jappix.org/
">Jappix
</a
>,
423 which I already introduced to some kids even before they got aware of
424 Facebook, making them see for themselves that they do not need
425 Facebook now ;).
</p
>
427 <p
><strong
>Which strategy do you believe is the right one to use to
428 get schools to use free software?
</strong
></p
>
430 <p
>Well, that
's a two-sided thing. One side is what I believe, and one
431 side is what I have experienced.
</p
>
433 <p
>I believe that the right strategy is showing them the benefits. But
434 that won
't work out as long as the acceptance of free alternatives
435 grows globally. What I mean is that if all the kids are almost forced
436 to use Windows, Facebook, Skype, you name it at home, they will not
437 see why they would want to use alternatives at school. I have seen
438 students take seat in front of a fully-functional, modern Debian
439 desktop that could do anything their Windows at home could do, and
440 they jsut refused to use it because
"Linux sucks
". It is something
441 that makes the council of our city spend around
600000 € to buy
442 software - not including hardware, mind you - for operating school
443 networks, and for installing a system that, as has been proved, does
444 not work. For those of you readers who are good at maths, have you
445 already found out how many lives could have been saved with that money
446 if we had instead used it to bring education to parts of the world
447 that need it? I have, and found it to be nothing less dramatic than
448 plain criminal.
</p
>
450 <p
>That said, the only feasible way appears to be the bottom up
451 method. We have to bring free software to kids and parents. I have
452 founded an association named
453 <a href=
"https://www.teckids.org
">Teckids
</a
> here in Germany that does
454 just that. We organise several events for kids and adolescents in the
455 area of free and open source software, for example the
456 <a href=
"http://kids.froscon.org
">FrogLabs
</a
>, which share staff with
457 Teckids and are the youth programme of
458 <a href=
"http://www.froscon.org
">the Free and Open Source Software
459 Conference (FrOSCon)
</a
>. We do a lot more than most other conferences
460 - this year, we first offered the FrogLabs as a holiday camp for kids
461 aged
10 to
16. It was a huge success, with approx.
30 kids taking part
462 and learning with and about free software through a whole weekend. All
463 of us had a lot of fun, and the results were really exciting.
</p
>
465 <p
>Apart from that, we are preparing a campaign that is supposed to bring
466 the message of free alternatives to stuff kids use every day to them and
467 their parents, e.g. the use of Jabber / Jappix instead of Facebook and
468 Skype. To make that possible, we are planning to get together a team of
469 clever kids who understand very well what their peers need and can bring
470 it across to them. So we will have a peer-driven network of adolescents
471 who teach each other and collect feedback from the community of minors.
472 We then take that feedback and our own experience to work closely with
473 open source projects, such as Skolelinux or Jappix, at improving their
474 software in a way that makes it more and more attractive for the target
475 group. At least I hope that we will have good cooperation with
476 Skolelinux in the future ;)!
</p
>
478 <p
>So in conclusion, what I believe is that, if it weren
't for the world
479 being so bad, it should be very clear to the political decision makers
480 that the only way to go nowadays is free software for various reasons,
481 but I have learnt that the only way that seems to work is bottom up.
</p
>
485 > * Who should be interviewed with this questions in the future?
487 That
's probably the hardest question of them all, as I do not know the
488 community. However, I would be willing to do the following:
490 <li
>Run an interview with a German headteacher who is very open to
491 free software, and also prefers it, but cannot really use it because
492 of the decision makers above;
493 <li
>Run interviews with some kids, both with and without previous
494 knowledge about free software
496 If that is wanted, just let me know ;).

508 but the
<a href=

512 his success story with installing Debian Edu at their school. This
513 time I have been able to get some helpful comments from the creator of
514 Knoppix, Klaus Knopper, who was involved in a Skolelinux project in
515 Germany a few years ago.

521 the university of applied sciences Kaiserslautern / Germany and
522 freelance Open Source software developer and consultant.

524 <p
>All of this is pretty much of the work I spend my days with. Apart
525 from teaching, I
'm also conducting some more or less experimental
526 projects like the

</strong

537 <p
>The credit for this have to go to Kurt Gramlich, who is the German
538 coordinator for Skolelinux. We were looking for an all-in-one open
539 source community-supported distribution for schools, and Kurt
540 introduced us to Skolelinux for this purpose.
</p

542 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
543 Edu?
</strong
></p
>
546 <li
>Quick installation,
</li
>
547 <li
>works (almost) out of the box,
</li
>
548 <li
>contains many useful software packages for teaching and learning,
</li
>
549 <li
>is a purely community-based distro and not controlled by a
550 single company,
</li
>
551 <li
>has a large number of supporters and teachers who share their
552 experience and problem solutions.
</li
>
555 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
556 Edu?
</strong
></p
>
559 <li
>Skolelinux is - as we had to learn - not easily upgradable to
560 the next version. Opposed to its genuine Debian base, upgrading to
561 a new version means a full new installation from scratch to get it
562 working again reliably.
564 <li
>Skolelinux is based on Debian/stable, and therefore always a
565 little outdated in terms of program versions compared to Edubuntu or
566 similar educational Linux distros, which rather use Debian/testing
569 <li
>Skolelinux has some very self-opinionated and stubborn default
570 configuration which in my opinion adds unnecessary complexity and is
571 not always suitable for a schools needs, the preset network
572 configuration is actually a core definition feature of Skolelinux
573 and not easy to change, so schools sometimes have to change their
574 network configuration to make it
"Skolelinux-compatible
".
576 <li
>Some proposed extensions, which were made available as
577 contribution, like secure examination mode and lecture material
578 distribution and collection, were not accepted into the mainline
579 Skolelinux development and are now not easy to maintain in the
580 future because of Skolelinux somewhat undeterministic update
583 <li
>Skolelinux has only a very tiny number of base developers
584 compared to Debian.
</li
>
588 <p
>For these reasons and experience from our project, I would now
589 rather consider using plain Debian for schools next time, until
590 Skolelinux is more closely integrated into Debian and becomes
591 upgradeable without reinstallation.
</p
>
593 <p
><strong
>Which free software do you use daily?
</strong
></p
>
595 <p
>GNU/Linux with LXDE desktop, bash for interactive dialog and
596 programming, texlive for documentation and correspondence,
597 occasionally LibreOffice for document format conversion. Various
598 programming languages for teaching.

600 <p
><strong
>Which strategy do you believe is the right one to use to
601 get schools to use free software?
</strong
></p
>
603 <p
>Strong arguments are
</p
>
607 <li
>Knowledge is free, and so should be methods and tools for
608 teaching and learning.
</li
>
610 <li
>Students can learn with and use the same software at school, at
611 home, and at their working place without running into license or
612 conversion problems.
</li
>
614 <li
>Closed source or proprietary software hides knowledge rather
615 than exposing it, and proprietary software vendors try to bind
616 customers to certain products. But teachers need to teach
617 science, not products.
</li
>
619 <li
>If you have everything you for daily work as open source, what
620 would you need proprietary software for?

><a href=
"http://www.skolelinux.org/
">Debian Edu, also known as
940 Skolelinux
</a
>, is a Linux distribution based on Debian providing an
941 out-of-the box environment of a completely configured school
942 network. Immediately after installation a school server running all
943 services needed for a school network is set up just waiting for users
944 and machines being added via GOsa², a comfortable Web-UI. A netbooting
945 environment is prepared using PXE, so after initial installation of
946 the main server from CD, DVD or USB stick all other machines can be
947 installed via the network. The provided school server provides LDAP
948 database and Kerberos authentication service, centralized home
949 directories, DHCP server, web proxy and many other services. The
951 <a href=
"http://people.skolelinux.org/pere/blog/Educational_applications_included_in_Debian_Edu___Skolelinux__the_screenshot_collection____.html
">more
952 than
60 educational software packages
</a
> and more are available from
953 the Debian archive, and schools can choose between KDE, Gnome, LXDE
954 and Xfce desktop environment.
</p
>
956 <p
>This is the fifth test release based on Debian Wheezy. Basically
957 this is an updated and slightly improved version compared to the
958 Squeeze release.
</p
>
960 <p
>ALERT: Alpha based installations should reinstall or downgrade the
961 versions of gosa and libpam-mklocaluser to the ones used in this beta
964 <p
><strong
>Software updates
</strong
></p
>
968 <li
>Switched roaming workstation profiles from wicd to network-manager
969 for network configuration, as wicd didn
't work any more.
</li
>
970 <li
>Changed version numbers of patched gosa and libpam-mklocaluser
971 packages to make sure our locally patched versions will be replaced
972 by the official packages when they are released from Debian. Those
973 installing alpha version need to reinstall or manually downgrade gosa
974 and libpam-mklocaluser.
</li
>
975 <li
>Added bluetooth tools to the default desktop (bluedevil, blueman).
</li
>
976 <li
>Added tools for sharing the desktop on KDE (krdc, krfb).
</li
>
977 <li
>Added valgrind to the default installation for easier debugging of
978 crash bugs.
</li
>
982 <p
><strong
>Other changes
</strong
></p
>
986 <li
>Fixed artwork package to work with gnome, no longer break
987 desktop=gnome installations.
</li
>
988 <li
>Adjusted installer to now work when forced to use a proxy with the
989 netinst CD.
</li
>
990 <li
>Fixed code detecting and setting/loading hardware specific
991 setup/firmware to work more robust out of the box.
</li
>
992 <li
>Adjusted Kerberos setup to detect realm and server settings at
993 install time instead of dynamically at run time. This avoid a crash
994 with krb5-auth-dialog on diskless workstations without a DNS name.
</li
>
995 <li
>Worked around misfeature in network-manager not calling the dhclient
996 exit hooks, causing automatic proxy configuration and automatic host
997 name setting at run time to work again.
</li
>
998 <li
>Fixed feature setting the default Iceweasel start page from URL
999 fetched from LDAP, to allow schools to set the global default by
1000 updating the dc=skole,dc=skolelinux,dc=no LDAP object.
</li
>
1001 <li
>Changed default host name on all networked machines to be unique
1002 (generated from MAC or reverse DNS) after boot.
</li
>
1003 <li
>Adjusted partition sizes to make sure they are big enough.
</li
>
1007 <p

1011 <li
>Grub is missing the new artwork.

1115 <li

</li
>
1116 <li
>Dropped menu-xdg from the KDE desktop option, to drop the Debian
1117 submenu. It was not included with Gnome, LXDE or Xfce, so this
1118 brings KDE in line with the others.
</li
>
1119 <li
>Dropped xdrawchem, xjig and xsok from our default installation as
1120 they don
't have a desktop menu entry and thus won
't show up in the
1121 menu now that menu-xdg was removed.
</li

1122 <li

1123 multi-user machines, as it was no longer able to understand when a
1124 X display was in use and killed the processes of the active users

>
1139 <li
>Made sure root and user passwords were not left behind in the
1140 debconf database after installation on Main Server installations.
</li
>
1141 <li
>Made Roaming Workstation dynamic setup more robust and added draft
1142 script setup-ad-client to hook a Roaming Workstation up to a
1143 Active Directory server instead of a Debian Edu Main Server.
</li

1144 <li

1148 and keymap settings to PXE installation clients.

>In the
<a href=

">Debian Edu /
1192 Skolelinux

1193 which check that services are running, working, and return the
1194 expected results. It runs automatically just after the first boot on
1195 test installations (using test ISOs), but not on production
1196 installations (using non-test ISOs). It test that the LDAP service is
1197 operating, Kerberos is responding, DNS is replying, file systems are
1198 online resizable, etc, etc. And it check that the PXE service is
1199 configured, which is the topic of this post.

've fixed the DVD and USB stick ISOs for our Debian

1203 complete system without any Internet connection, but for that to
1204 happen all the needed packages need to be on them. Thanks to our test
1205 suite, I discovered that we had forgotten to adjust our PXE setup to
1206 cope with the new names and paths used by the netboot d-i packages.
1207 When Internet connectivity was available, the installer fall back to
1208 using wget to fetch d-i boot images, but when offline it require
1209 working packages to get it working. And the packages changed name
1210 from debian-installer-
6.0-netboot-$arch to
1211 debian-installer-
7.0-netboot-$arch, we no longer pulled in the
1212 packages during installation. Without our test suite, I suspect we
1213 would never have discovered this before release. Now it is fixed
1214 right after we got the ISOs operational.

1216 <p
>Another by-product of the test suite is that we can ask system
1217 administrators with problems getting Debian Edu to work, to run the
1218 test suite using
<tt
>/usr/sbin/debian-edu-test-install
</tt
> and see if
1219 any errors are detected. This usually pinpoint the subsystem causing
1220 the problem.

>The
<a href=
"http://www.skolelinux.org/
">Debian Edu and
1237 Skolelinux
</a
> distribution have users and contributors all around the
1238 globe. And a while back, an enterprising young man showed up on
1239 <a href=
"irc://irc.debian.org/%
23debian-edu
">our IRC channel
1240 #debian-edu
</a
> and started asking questions about how Debian Edu
1241 worked. We answered as good as we could, and even convinced him to
1242 help us with translations. And today I managed to get an interview
1243 with him, to learn more about him.
</p

1245 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
1247 <p
>I
'm a
25 year old free software enthusiast, living in Romania,
1248 which is also my country of origin. Back in
2009, at a New Year
's Eve
1249 party, I had a very nice
<strike
>beer
</strike
> discussion with a
1250 friend, when we realized we have no organised Debian community in our
1251 country. A few days later, we put together the infrastructure for such
1252 community and even gathered a nice Debian-ish crowd. Since then, I
1253 began my quest as a free software hacker and activist and I am
1254 constantly trying to cover as much ground as possible on that
1257 <p
>A few years ago I founded a small web development company, which
1258 provided me the flexible schedule I needed so much for my
1259 activities. For the last
13 months, I have been the Technical Director
1260 of
<a href=
"http://ceata.org/
">Fundația Ceata
</a
>, which is a free
1261 software activist organisation endorsed by the FSF and the FSFE, and
1262 the only one we have in our country.
</p
>
1264 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
1265 project?
</strong
></p
>
1267 <p
>The idea of participating in the Debian Edu project was a surprise
1268 even to me, since I never used it before I began getting involved in
1269 it. This year I had a great opportunity to deliver a talk on
1270 educational software, and I knew immediately where to look. It was a
1271 love at first sight, since I was previously involved with some of the
1272 technologies the project incorporates, and I rapidly found a lot of
1273 ways to contribute.
</p
>
1275 <p
>My first contributions consisted in translating the installer and
1276 configuration dialogs, then I found some bugs to squash (I still
1277 haven
't fixed them yet though), and I even got my eyes on some other
1278 areas where I can prove myself helpful. Since the appetite for free
1279 software in my country is pretty low, I
'll be happy to be the first
1280 one around here advocating for the project
's adoption in educational
1281 environments, and maybe even get my hands dirty in creating a flavour
1282 for our own needs. I am not used to make very advanced plannings, so
1283 from now on, time will tell what I
'll be doing next, but I think I
1284 have a pretty consistent starting point.
</p
>
1286 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
1287 Edu?
</strong
></p
>
1289 <p
>Not a long time ago, I was in the position of configuring and
1290 maintaining a LDAP server on some Debian derivative, and I must say it
1291 took me a while. A long time ago, I was maintaining a bigger
1292 Samba-powered infrastructure, and I must say I spent quite a lot of
1293 time on it. I have similar stories about many of the services included
1294 with Skolelinux, and the main advantage I see about it is the
1295 out-of-the box availability of them, making it quite competitive when
1296 it comes to managing a school
's network, for example.
</p
>
1298 <p
>Of course, there is more to say about Skolelinux than the
1299 availability of the software included, its flexibility in various
1300 scenarios is something I can
't wait to experiment
"into the wild
" (I
1301 only played with virtual machines so far). And I am sure there is a
1302 lot more I haven
't discovered yet about it, being so new within the
1305 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
1306 Edu?
</strong
></p
>
1308 <p
>As usual, when it comes to Debian Blends, I see as the biggest
1309 disadvantage the lack of a numerous team dedicated to the
1310 project. Every day I see the same names in the changelogs, and I have
1311 a constantly fear of the bus factor in this story. I
'd like to see
1312 Debian Edu advertised more as an entry point into the Debian
1313 ecosystem, especially amongst newcomers and students. IMHO there are a
1314 lot low-hanging fruits in terms of bug squashing, and enough
1315 opportunities to get the feeling of the Debian Project
's dynamics. Not
1316 to mention it
's a very fun blend to work on!
</p
>
1318 <p
>Derived from the previous statement, is the delay in catching up
1319 with the main Debian release and documentation. This is common though
1320 to all blends and derivatives, but it
's an issue we can all work
1323 <p
><strong
>Which free software do you use daily?
</strong
></p
>
1325 <p
>I can hardly imagine myself spending a day without Vim, since my
1326 daily routine covers writing code and hacking configuration files. I
1327 am a fan of the Awesome window manager (but I also like the
1328 Enlightenment project a lot!),
1329 <a href=
"http://www.claws-mail.org/
">Claws Mail
</a
> due to its ease of
1330 use and very configurable behaviour. Recently I fell in love with
1331 <a href=
"https://launchpad.net/redshift
">Redshift
</a
>, which helps me
1332 get through the night without headaches. Of course, there is much more
1333 stuff in this bag, but I
'll need a blog on my own for doing this!
</p
>
1335 <p
><strong
>Which strategy do you believe is the right one to use to
1336 get schools to use free software?
</strong
></p
>
1338 <p
>Well, on this field, I cannot do much more than experiment right
1339 now. So, being far from having a recipe for success, I can only assume
1344 <li
>schools would like to get rid of proprietary software
</li
>
1346 <li
>students will love the openness of the system, and will want to
1347 experiment with it - maybe we need to harvest the native curiosity
1348 of teenagers more?
</li
>
1350 <li
>there is no
"right one
" when it comes to strategies, but it would
1351 be useful to have some success stories published somewhere, so
1352 other can get some inspiration from them (I know I
'd promote
1355 <li
>more active promotion - talks, conferences, even small school
1356 lectures can do magical things if they encounter at least one
1357 person interested. Who knows who that person might be? ;-)
</li
>
1361 <p
>I also see some problems in getting Skolelinux into schools; for
1362 example, in our country we have a great deal of corruption issues, so
1363 it might be hard(er) to fight against proprietary solutions. Also,
1364 people who relied on commercial software for all their lives, would be
1365 very hard to convert against their will.

</a

<a href=

1379 Jonathan Carter, which I am now happy to present to you.

1381 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p

1383 <p
>I
'm a South-African free software geek who lives in Cape Town. My
1384 days vary quite a bit since I
'm involved in too many things. As I
'm
1385 getting older I
'm learning how to focus a bit more :)
</p
>
1387 <p
>I
'm also an Edubuntu contributor and I love when there are
1388 opportunities for the Edubuntu and Debian Edu projects to benefit from
1389 each other.
</p
>
1391 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
1392 project?
</strong
></p
>
1394 <p
>I
've been somewhat familiar with the project before, but I think my
1395 first direct exposure to the project was when I met Petter
1396 [Reinholdtsen] and Knut [Yrvin] at the Edubuntu summit in
2005 in
1397 London. They provided great feedback that helped the bootstrapping of
1398 Edubuntu. Back then Edubuntu (and even Ubuntu) was still very new and
1399 it was great getting input from people who have been around longer. I
1400 was also still very excitable and said yes to everything and to this
1401 day I have a big todo list backlog that I
'm catching up with. I think
1402 over the years the relationship between Edubuntu and Debian-Edu has
1403 been gradually improving, although I think there
's a lot that we could
1404 still improve on in terms of working together on packages. I
'm sure
1405 we
'll get there one day.
</p
>
1407 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
1408 Edu?
</strong
></p
>
1410 <p
>Debian itself already has so many advantages. I could go on about
1411 it for pages, but in essence I love that it
's a very honest project
1412 that puts its users first with no hidden agendas and also produces
1413 very high quality work.
</p
>
1415 <p
>I think the advantage of Debian Edu is that it makes many common
1416 set-up tasks simpler so that administrators can get up and running
1417 with a lot less effort and frustration. At the same time I think it
1418 helps to standardise installations in schools so that it
's easier for
1419 community members and commercial suppliers to support.
</p
>
1421 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
1422 Edu?
</strong
></p
>
1424 <p
>I had to re-type this one a few times because I
'm trying to
1425 separate
"disadvantages
" from
"areas that need improvement
" (which is
1426 what I originally rambled on about)
</p
>
1428 <p
>The biggest disadvantage I can think of is lack of manpower. The
1429 project could do so much more if there were more good contributors. I
1430 think some of the problems are external too. Free software and free
1431 content in education is a no-brainer but it takes some time to catch
1432 on. When you
've been working with the same proprietary eco-system for
1433 years and have gotten used to it, it can be hard to adjust to some
1434 concepts in the free software world. It would be nice if there were
1435 more Debian Edu consultants across the world. I
'd love to be one
1436 myself but I
'm already so over-committed that it
's just not possible
1437 currently.
</p
>
1439 <p
>I think the best short-term solution to that large-scale problem is
1440 for schools to be pro-active and share their experiences and grow
1441 their skills in-house. I
'm often saddened to see how much money
1442 educational institutions spend on
3rd party solutions that they don
't
1443 have access to after the service has ended and they could
've gotten so
1444 much more value otherwise by being more self-sustainable and
1445 autonomous.
</p
>
1447 <p
><strong
>Which free software do you use daily?
</strong
></p
>
1449 <p
>My main laptop dual-boots between Debian and Windows
7. I was
1450 Windows free for years but started dual-booting again last year for
1451 some games which help me focus and relax (Starcraft II in
1452 particular). Gaming support on Linux is improving in leaps and bounds
1453 so I suppose I
'll soon be able to regain that disk space :)
</p
>
1455 <p
>Besides that I rely on Icedove, Chromium, Terminator, Byobu, irssi,
1456 git, Tomboy, KVM, VLC and LibreOffice. Recently I
've been torn on
1457 which desktop environment I like and I
'm taking some refuge in Xfce
1458 while I figure that out. I like tools that keep things simple. I enjoy
1459 Python and shell scripting. I went to an Arduino workshop recently and
1460 it was awesome seeing how easy and simple the IDE software was to get
1461 up and running in Debian compared to the users running Windows and OS
1464 <p
>I also use mc which some people frown upon slightly. I got used to
1465 using Norton Commander in the early
90's and it stuck (I think the
1466 people who sneer at it is just jealous that they don
't know how to use

><strong
>Which strategy do you believe is the right one to use to
1470 get schools to use free software?
</strong
></p
>
1472 <p
>I think trying to force it is unproductive. I also think that in
1473 many cases it
's appropriate for schools to use non-free systems and I
1474 don
't think that there
's any particular moral or ethical problem with
1477 <p
>I do think though that free software can already solve so so many
1478 problems in educational institutions and it
's just a shame not taking
1479 advantage of that.
</p
>
1481 <p
>I also think that some curricula need serious review. For example,
1482 some areas of the world rely heavily on very specific versions of MS
1483 Office, teaching students to parrot menu items instead of learning the
1484 general concepts. I think that
's very unproductive because firstly, MS
1485 Office
's interface changes drastically every few years and on top of
1486 that it also locks in a generation to a product that might not be the
1487 best solution for them.
</p
>
1489 <p
>To answer your question, I believe that the right strategy is to
1490 educate and inform, giving someone the information they require to
1491 make a decision that would work for them.

">Debian Edu, also known as
1512 Skolelinux
</a

1513 out-of-the box environment of a completely configured school
1514 network. Immediately after installation a school server running all
1515 services needed for a school network is set up just waiting for users
1516 and machines being added via GOsa², a comfortable Web-UI. A netbooting
1517 environment is prepared using PXE, so after initial installation of
1518 the main server from CD, DVD or USB stick all other machines can be
1519 installed via the network. The provided school server provides LDAP
1520 database and Kerberos authentication service, centralized home
1521 directories, DHCP server, web proxy and many other services. The

1621 We have two problems blocking the release of the Wheezy version we
1622 hope to get released soon. The two problems require some with PHP

1655 interview last November. But the developers and translators are still
1656 pulling along to get the Wheezy based release out the door, and this
1657 time I managed to get an interview from one of the French translators
1658 in the project, Cédric Boutillier.

1660 <p

>Who are you, and how do you spend your days?
</strong
></p
>
1662 <p
>I am
34 year old. I live near Paris, France. I am an assistant
1663 professor in probability theory. I spend my daytime teaching
1664 mathematics at the university and doing fundamental research in
1665 probability in connexion with combinatorics and statistical physics.
</p
>
1667 <p
>I have been involved in the Debian project for a couple of years
1668 and became Debian Developer a few months ago. I am working on Ruby
1669 packaging, publicity and translation.

1671 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
1672 project?
</strong
></p
>
1674 <p
>I came to the Debian Edu project after a call for translation of
1675 <a href=
"http://wiki.debian.org/DebianEdu/Documentation/Manuals
">the
1676 Debian Edu manual
</a
> for the release of Debian Edu Squeeze. Since
1677 then, I have been working on updating the French translation of the

>I had the opportunity to make an installation of Debian Edu in a
1681 virtual machine when I was preparing localised version of some screen
1682 shots for the manual. I was amazed to see it worked out of the box and
1683 how comprehensive the list of software installed by default was.
</p
>
1685 <p
>What amazed me was the complete network infrastructure directly
1686 ready to use, which can and the nice administration interface provided
1687 by
<a href=
"https://oss.gonicus.de/labs/gosa/
">GOsa²
</a
>. What pleased
1688 me also was the fact that among the software installed by default,
1689 there were many
"traditional
" educative software to learn languages,
1690 to count, to program... but also software to develop creativity and
1691 artistic skills with music (
<a href=
"http://ardour.org/
">Ardour
</a
>,
1692 <a href=
"http://audacity.sourceforge.net/
">Audacity
</a

1693 movies/animation (I was especially thinking of
1694 <a href=
"http://linuxstopmotion.sourceforge.net/
">Stopmotion
</a

't much time to get more involved in this

1701 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
1702 Edu?
</strong
></p
>
1704 <p
>For me, the main advantages of Skolelinux/Debian Edu are its
1705 community of experts and its precise documentation, as well as the
1706 fact that it provides a solution ready to use.
</p
>
1708 <p
>I would add also the fact that it is based on the rock solid Debian
1709 distribution, which ensures stability and provides a huge collection
1710 of educational free software.
</p
>
1712 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
1713 Edu?
</strong
></p
>
1715 <p
>Maybe the lack of manpower to do lobbying on the
1716 project. Sometimes, people who need to take decisions concerning IT do
1717 not have all the elements to evaluate properly free software
1718 solutions. The fact that support by a company may be difficult to find
1719 is probably a problem if the school does not have IT personnel.
</p
>
1721 <p
>One can find support from a company by looking at
1722 <a href=
"http://wiki.debian.org/DebianEdu/Help/ProfessionalHelp
">the
1723 wiki dokumentation
</a
>, where some countries already have a number of
1724 companies providing support for Debian Edu, like Germany or
1725 Norway. This list is easy to find readily from the manual. However,
1726 for other countries, like France, the list is empty. I guess that
1727 consultants proposing support for Debian would be able to provide some
1728 support for Debian Edu as well.
</p
>
1730 <p
><strong
>Which free software do you use daily?
</strong
></p
>
1732 <p
>I am using the KDE Plasma Desktop. But the pieces of software I use
1733 most runs in a terminal: Mutt and OfflineIMAP for emails, latex for
1734 scientific documents, mpd for music. VIM is my editor of choice. I am
1735 also using the mathematical software
1736 <a href=
"http://www.scilab.org/en/scilab/about
">Scilab
</a
> and
1737 <a href=
"http://www.sagemath.org/index.html
">Sage
</a
> (built from
1738 source as not completely packaged for Debian, yet).
1740 <p
><strong
>Do you have any suggestions for teachers interested in
1741 using the free software in Debian to teach mathematics and
1742 statistics?
</strong
></p
>
1744 <p
>I do not have any
"nice
" recommendations for statistics. At our
1745 university, we use both
<a href=
"http://www.r-project.org/
">R

> and
1746 Scilab to teach statistics and probabilistic simulations. For
1747 geometry, there are nice programs:

1752 <a href=

><a href=

1756 to discover symmetry groups (the so-called wallpapers and frieze

1934 Stopmotion
</a
> resultat av et studentprosjekt i Skolelinux. De siste
1935 månedene har en ivrig student veiledet av Marius Kotsbak i
1936 <a href=
"http://www.friprogramvareiskolen.no/
">FRiSK
</a

1937 kan få til med en datamaskin til NOK
400,- (antagelig
1700,- med
1938 skjerm, tastatur og mus) når det brukes i Skolelinux. Jeg spurte han
1939 om et intervju.
</p

1941 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
1943 <p
>Jeg heter Nirosan Thiyagalingam. Jeg er
24 år og studerer
1944 dataingeniør studiet ved Høgskolen i Sør Trøndelag. Interessen for
1945 data har siden ung alder vært tilstede og jeg har i tillegg alltid
1946 vært glad i å lære nye ting. Med teknologi som endres svært hurtig er
1947 det alltid noe nytt å lære. Noe som igjen har gjort det svært
1948 interessant å følge med på utviklingen. Jeg valgte dataingeniør
1949 studiet grunnet ønske om å lære enda mer om programmering og utvikling
1950 av store systemer.
</p
>
1952 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
1954 <p
>Skolelinux prosjektet hørte jeg først om i media. Men det var først
1955 når jeg skulle velge bacheloroppgave at jeg fattet mer interesse for
1956 prosjektet. Et enkelt søk på nettet førte meg til skolelinux sine
1957 hjemmesider. Informasjonen jeg fant der gjorde meg enda nysgjerrig og
1958 jeg valgte derfor en oppgave som gikk ut på å få en
1959 <a href=
"http://www.raspberrypi.org
">Raspberry PI
</a
>. Altså en
1960 ultra-billig datamaskin til å kjøre Debian Edu på lik linje med
1961 vanlige datamaskiner. I løpet av prosjektet ble det gjort mye
1962 forskning på nettet. Det var mye jeg måtte forstå rundt hvordan
1963 operativsystemet Linux fungerte før jeg kunne angripe
1964 problemet. Prøvde først å finne ut hvordan man kunne transformere en
1965 vanlig installasjon av Skolelinux til Raspberry PI, men dette var
1966 altfor vanskelig å jeg endte opp med mer spørsmål enn svar. Det ble
1967 videre opprettet kontakt med Skolelinux utviklere på IRC der jeg fikk
1968 diskutert hvilken retning jeg burde gå for å få til en fullverdig
1969 løsning. Det ble bestemt at jeg skulle gå for å først installere
1970 <a href=
"http://www.raspbian.org/
">Raspian
</a
>. Dette er et
1971 operativsystem basert på Debian spesiallaget for Raspberry Pi sin
1972 maskinvare. Nå som Debian var installert på datamaskinen gjenstod det
1973 å installere de nødvendige Skolelinux pakkene for å få til et
1974 fullverdig system. Disse pakkene ble installert manuelt i første
1975 omgang, men ble senere installert automatisk via et script som Petter
1976 Reinholdtsen laget. Dette scriptet er så enkel å bruke at man er i
1977 gang med installasjonen i løpet av bare
5 minutter. Ikke nok med det,
1978 alt skjer helt automatisk. Alt i alt er jeg veldig fornøyd med
1979 resultatet av installasjonsprosessen. Raspberry Pi er en veldig svak
1980 maskin og det merkes godt når man har installert Skolelinux på
1981 den. Video og
3D-rendering fungerer utrolig dårlig, men nettsurfing og
1982 kontorprogrammer fungerer godt. Det kan derfor konkluderes med at
1983 datamaskinen er egnet for enkle oppgaver.
1985 <p
>Jeg syns det er viktig påpeke at dette kun er startfasen av en slik
1986 løsning. På markedet finnes det nå maskiner som har bedre hardware enn
1987 Raspberry Pi. Det er store muligheter for at man kan klare å
1988 installere Skolelinux på disse også, og da forsvinner nok mest
1989 sannsynlig ytelsesproblemene med Video og
3D rendering også.
</p
>
1991 <p
>Det ble også prøvd med en løsning som gjorde at Raspberry Pi
1992 fungerte som en tynnklient. Denne løsningen hadde langt bedre ytelse
1993 med tanke på hastighet og brukeropplevelse. Men også her var video og
1994 3D rendering dårlig. Det ble brukt en liten Linux distribusjon kalt
1995 <a href=
"http://www.berryterminal.com/
">BerryTerminal
</a
> for å få til
1998 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
2000 <p
>Fordelen med Skolelinux er mange. At det er gratis er en stor
2001 fordel, men at det er så mange som er med på å utvikle det og
2002 vedlikeholde det er en enda større fordel. Allerede før jeg startet
2003 med prosjektet så jeg mange fordeler, og når jeg nærmet meg sluttfasen
2004 så jeg langt flere. At prosjektet skulle inneha en så høy kvalitet
2005 hadde jeg aldri trodd. En vanlig Skolelinux installasjon har de
2006 nødvendige programmene og funksjonen som både små og store skoler i
2007 tillegg til organisasjoner kan klare seg med. At prosjektet tilbyr en
2008 så komplett løsning er en kjempefordel. Installasjonen er knirkefri
2009 og det er svært enkelt å installere og komme i gang.
</p
>
2011 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
2013 <p
>Ulempene jeg ser med prosjektet er ryddigheten av websidene. Selv
2014 om websidene er enkle og konsise er det allikevel ikke appellerende i
2015 like stor grad som for eksempel
2016 <a href=
"http://www.ubuntu.com
">Ubuntu
</a
> sine sider. Deres side
2017 tilbyr, i tillegg til godt design og presentasjon, en nettbasert
2018 emulator av deres operativsystem. Dette er en stor fordel slik jeg ser
2019 det. Bortsett fra dette ser jeg absolutt ingen ulemper med
2020 Skolelinux-prosjektet.
</p
>
2022 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
2024 <p
>Til daglig er jeg en flittig bruker av det åpne media
2025 sentersystemet
<a href=
"http://xbmc.org/
">XBMC
</a
>. Det enorme
2026 samfunnet rundt dette prosjektet har gjort dette til et program som
2027 dekker alles behov. Man kan tilpasse det akkurat slik man vil både med
2028 tanke på utseende og funksjoner ved installere plug-ins eller
2031 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
2032 skoler til å ta i bruk fri programvare?
</strong
></p
>
2034 <p
>Strategien som burde brukes sett fra mine øyne er
2035 markedsføring. Jeg er sikker på at om flere skoler fikk et lite innsyn
2036 i hvor bra Skolelinux er så ville de ikke nølt med å gå over fra noe
2037 annet som koster de store summer. At skolelinux til de grader tilbyr
2038 en så komplett løsning bure komme frem. Enten via reklamekampanjer
2039 eller ved å sende ut folk til skoler for så å la skolenettverk
2040 ansvarlige få teste ut hvordan Skolelinux fungerer i praksis. Om det
2041 i tillegg ble utviklet gode websider og en emulator for å la brukere
2042 prøve operativsystemet ville nok dette ha styrket inntrykket
2043 betraktelig.

2055 pupils in the primary schools. It provide both the central server,
2056 network boot servers and desktop environments with heaps of
2057 educational software. The project was founded almost
12 years ago,

2063 <p
>A topic that come up again and again on the Debian Edu mailing
2064 lists and elsewhere, is the question on how to transform a Debian or
2065 Ubuntu installation into a Debian Edu installation. It isn
't very
2066 hard, and last week I wrote a script to replicate the steps done by
2067 the Debian Edu installer.
</p

2069 <p
>The script,

">debian-edu-bless
<a/
>
2071 in the debian-edu-config package, will go through these six steps and
2072 transform an existing Debian Wheezy or Ubuntu (untested) installation
2073 into a Debian Edu Workstation:
</p
>
2077 <li
>Add skolelinux related APT sources.
</li
>
2078 <li
>Create /etc/debian-edu/config with the wanted configuration.
</li
>
2079 <li
>Install debian-edu-install to load preseeding values and pull in
2080 our configuration.
</li
>
2081 <li
>Preseed debconf database with profile setup in
2082 /etc/debian-edu/config, and run tasksel to install packages
2083 according to the profile specified in the config above,
2084 overriding some of the Debian automation machinery.
</li
>
2085 <li
>Run debian-edu-cfengine-D installation to configure everything
2086 that could not be done using preseeding.
</li
>
2087 <li
>Ask for a reboot to enable all the configuration changes.
</li
>
2091 <p
>There are some steps in the Debian Edu installation that can not be
2092 replicated like this. Disk partitioning and LVM setup, for example.
2093 So this script just assume there is enough disk space to install all
2094 the needed packages.
</p

2096 <p

2097 setting up
<a href=

2100 transform it into a fully functioning Debian Edu Workstation (or
2101 Roaming Workstation, or whatever :).
</p
>
2103 <p
>The default setting in the script is to create a KDE Workstation.
2104 If a LXDE based Roaming workstation is wanted instead, modify the

2140 server running all services needed for a school network is set up just
2141 waiting for users and machines being added via GOsa², a comfortable
2142 Web-UI. A netbooting environment is prepared using PXE, so after
2143 initial installation of the main server from CD, DVD or USB stick all
2144 other machines can be installed via the network.

2231 i Narvikskolene og konstnaden ved å gå over til Windows. For litt

9 millioner
2241 for å gå over til Windows på skolene. I tillegg dokumenterer notatet
2242 at læreplanens krav oppfylles uten problemer ved bruk av Skolelinux.
2243 Jeg anbefaler alle å lese de
10 sidene med gode argumenter for å kutte
2244 unødige utgifter på IT i skoleverket. :)

2431 a few programs and his view of our distribution.
</p

2433 <p
>There is also some really nice quotes (transcribed by me, might
2434 have heard wrong). While looking thought the Graphics menu:
</p

2437 "Basically everything you ever need in a school environment.
"
2440 <p
>And as a general evaluation of the entire distribution:
</p
>
2443 "So, yeah, a bit bloated. It kept all the Debian stuff in there, just
2444 to keep it nice and GNU. So, I do not want to go on about it, but
2445 lets give it
7 out of
10. I am not going to use it. That is because
2446 I am not deploying a school network. There may be some mythical
2447 feature to help you deploy Skolelinux on a school network.
"
2450 <p
>To bad he did not test the server profile, and discovered the PXE
2451 installation option. It make it possible to install only the main
2452 server from CD, and the rest of the machines via the net, and might be
2453 considered the mythical feature he talk about. :)
</p
>
2455 <p
>While looking through the menus, there is also this funny comment
2456 about the part of the K menu generated from the Debian menu subsystem:
2459 "[The K menu] have a special Debian section for software that no-one
2460 is going to look at, because it contain lots of junky stuff that you
2461 actually don
't need in the education distribution, but have just been
2462 included because it isn
't stripped out for some reason.
"
2465 <p
>I guess it is yet another argument for merging the Debian menu and
2466 Gnome/KDE desktop menu entries into
2467 <a href=

>Etter en lang pause og travle uker har jeg endelig klart å få
2581 samlet et nytt intervju med en av folkene i
2582 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet.
2583 Denne gang er det Helge Tore Høyland, en mangeårig bidragsyter på
2584 epostlistene og ellers i prosjektet.
</p
>
2586 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
2588 <p
>Eg er IT-konsulent/teknikker hjå eit firma i Steinkjer med navn
2589 <a href=
"http://unoit.no/
">Uno IT
</a
>. Uno IT er eit lite firma som
2590 drifter nettverk og maskiner for små og mellomstore firma
2591 Steinkjer-området. Per dags dato er me
2 ansatte. Min faglege bakgrunn
2592 er Fagbrev som it-teknikker, samt nokre fag innen nettverk- og
2593 server-drift frå HiST og NTNU. Dagleg arbeid består i oppsett av nye
2594 maskiner og hjelp til sluttbrukere, samt oppsett og vedlikehold av eit
2595 vidt spekter av fagsystemer ute hjå kunder. Erfaring med Skolelinux
2596 har eg hatt i forbindelse med drifting av
2597 <a href=
"http://www.bjorkly.no/
">Bjørkly skule
</a
>, ein privat
2598 grunnskule i Namsos-området. I dag har skulen
65 elever,
15 lærere,
1
2599 hovedserver og ca
60 klienter som kjører halvtjukt. Eg har bygd og
2600 driftet systemet sidan summaren
2006.
</p
>
2602 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
2604 <p
>Eg kom i kontakt med Skolelinux-prosjektet via ein artikkel i eit
2605 fagblad, som eg ikkje lenger hugsar namnet på. I og med at eg allereie
2606 hadde pusla med nettverk for ein annan skule, fatta eg straks
2607 interesse for prosjektet.
</p
>
2609 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
2611 <p
>Fordelane med Skolelinux er sentralisert administrasjon og svært
2612 mange gode verktøy «ut av boksen». Veldig kjekt å kunne drifte
60
2613 klientar med berre å «bry» seg med ein server. Levetid for systemets
2614 hardware er og ein veldig fin effekt. I tillegg kjem fordelar som økt
2615 sikkerhet og mindre lisenskostnader. Etter min erfaring er det og
2616 mykje mindre driftskostnader med eit slikt system enn konkurrerande
2617 system, pga enkelhet med sentralisert administrasjon. På grunn av at
2618 Skolelinux er basert på Debian er det òg svært stabilt.
</p
>
2620 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
2622 <p
>Ulemper er mangel på vilje til å følge standarer ute i markedet,
2623 som fører til mangel på støtte til nokre mykje brukte ting. Flash og
2624 Java er typiske eksempel. Sidan Debian satsar på stabilitet framfor å
2625 ha nyeste pakke av eit program, kan ein i nokre tilfeller kome borti
2626 at program vert «for gamle». Det er spesielt nettlesaren som er
2627 utsett. Mangel på vilje til å utvikle pedagogisk programvare, i Noreg,
2628 for «alle» platformer fører òg til noko hovudbry.
</p
>
2630 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
2632 <p
>Til dagleg bruker eg svært mange forskjellige «fri programvare»
2633 program. Firefox, Thunderbird, Freecommander, ImgBurn, Clonezilla,
2634 OCS inventory, Icinga, Skolelinux, SystemRescueCD og mykje meir.
</p
>
2636 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
2637 skoler til å ta i bruk fri programvare?
</strong
></p
>
2639 <p
>Strategisk må ein fokusere på at sluttbruker eigentleg ikkje er så
2640 fokusert på at det er fri programvare men at det skal «berre fungere».
2641 Gjer det enkelt å bruker og ikkje minst å administrere. For Skolelinux
2642 sin del må ein få eit betre fokus på overganger. Utbytting av servere
2643 må gå meir automatisk, import og eksport av brukerbase og maskinbase
2644 med meir må kunne gå enkelt og oppgradering til neste versjon må bli
2645 mykje meir automatisk og gjennomtesta. Ein må unngå at ein må sette
2646 opp frå start når ein byter ut ein server eller oppgraderer til neste
2647 versjon. For å få Skolelinux til å bli eit betre alternativ for skular
2648 må ein ha fokus på nettlesaren. Denne må bli «up to date» og støtte
2649 dei protokollar og tillegg som vert brukt av forlag med meir. Etter
2650 kvart som meir og meir blir flytta ut i «skya» vert dette viktigare og
2651 viktigare. Ein kunne ynskje og jobbe for at forlag med fleire tar i
2652 bruk opne standarer, men inntil det skjer, må systemet kunne brukast
2653 mot desse fagsystema.
</p
>
2655 <p
>For meg har prosjektet med Skolelinux vore ein svært artig og
2656 lærerik prosess. Miljøet rundt er ikkje enormt stort, dog stort nok,
2657 men det er svært hjelpevillig og engasjert.

2674 cost around NOK

2694 interesting, as I am involved with several organizations where
2695 accounting is an issue, and I have not really become too friendly with
2696 the different web based systems we use. I find it hard to find what I
2697 look for in the menus and even harder try to get sensible data out of
2698 the systems. Ledger seem different. The accounting data is kept in
2699 text files that can be stored in a version control system, and there
2701 are at least
<a href=

2767 Besides that I am really involved into and occupied with several inner

2013 I will work again in my job in a German foundation for

2774 that - and that is the connection to Skolelinux / Debian Edu - I am

2787 <p

2789 <p
>Very soon after getting to know him I was completely enrolled into
2790 Free Software. At this time Mike did IT-services for one newly
2791 founded school in Kiel. Other schools in Kiel needed concepts for
2792 their IT environment. Often when Mike came home from working at the
2793 newly founded school I found myself listening to his complaints about
2794 several points where the communication with the schools head or the
2795 teachers did not work. So we were clear that he would not work for
2796 one more school if we did not set up a structure for communication
2797 between him, the schools head, the teachers, the students and the
2800 <p
>Together with our friend and hardware supplier Andreas Buchholz we
2801 started to get an overview of free software solutions suitable for
2802 schools. One day before Christmas
2010 Mike and I had a date with Kurt
2803 Gramlich in Gütersloh. As Kurt and I are really interested in building
2804 networks of people and in being in communication we dived into
2805 Skolelinux and brought it to the first grammar schools in Northern

>What do you see as the advantages of Skolelinux / Debian

</strong
></p

2815 <p
>First I have to say: I cannot answer this question technically. My
2816 answer comes rather from a social point of view.
</p
>
2818 <p
>The biggest advantage of Skolelinux / Debian Edu I see is the large
2819 and strong international community of Debian Developers in the
2820 background which is very alive and connected over mailinglists, blogs
2821 and meetings. My constant feeling for the Debian Community is: If
2822 something does not work they will somehow fix it. All is well
2823 ;-). This is of course a user experience. What I also get as a big
2824 advantage of Skolelinux / Debian Edu is that everybody who uses it and
2825 works with it can also contribute to it - that includes students,
2826 teachers, parents...
</p
>
2828 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
2829 Edu?
</strong
></p
>
2831 <p
>I will answer this question relating to the internal structure of
2832 Skolelinux / Debian Edu.
</p
>
2834 <p
>What I see as a major disadvantage is that there is a gap between
2835 the group of developers for Debian Edu and the people who make the
2836 marketing, that means the people that bring Skolelinux to the
2837 schools. There is a lack of communication between these two groups and
2838 I think that does not really work for Skolelinux / Debian Edu.
</p
>
2840 <p
>Further I appreciate that Skolelinux / Debian Edu is known as a
2841 do-ocracy. Nevertheless I keep asking myself if at some points a
2842 democracy or some kind of hierarchical project structure would be good
2843 and helpful. I am also missing some kind of contact between the
2844 Skolelinux / Debian Edu communities in Europe or on an international
2845 level. I think it would be good if there was more sharing between the
2846 different countries using Skolelinux / Debian Edu.

2851 on. As applications I use Openoffice.org, Gedit, Firefox, Pidgin,
2852 LaTeX and GnuCash. For mails I am using Horde. And I am really fond of
2853 my N900 running with Maemo.
</p

2855 <p
><strong
>Which strategy do you believe is the right one to use to
2856 get schools to use free software?
</strong
></p
>
2858 <p
>I am really convinced that in our school project
"IT-Zukunft
2859 Schule
" we have developed (and keep developing) a great way to get
2860 schools to use Free Software. We have written a detailed concept for
2861 that so I cannot explain the whole thing here. But in a nutshell the
2862 strategy has three crucial pillars:
</p
>
2866 <li
>We really take time to get what sort of stories, questions and
2867 concerns the schools head and the teachers have about using different
2868 kinds of IT and we take time to enrol them into Free Software.
</li
>
2870 <li
>Our solution for schools is never just technical. In the centre
2871 are always the people who are going to use the software. From the very
2872 beginning of the planning for a school, we tell the schools head that
2873 they are paying us not only for a technical solution for their school,
2874 they also pay us for leading all the communication processes
2875 needed. If they do not want that, we are not working with them because
2876 we cannot give a guarantee for the quality of our work then.
</li
>
2878 <li
>Another focus lies in the training of teachers and students in
2879 co-administrating the IT-System at their school. They start getting in
2880 contact with the Skolelinux / Debian Edu community and they get the
2881 offer to become more and more independent from us.

2904 <p
>I sommer (
2012-
07-
23) hadde Fremover et oppslag om at Narvik
2905 kommune hadde spart mellom
10 og
20 millioner kroner de siste årene på
2906 å bruke Skolelinux på sine skoler. Harstad har også tatt i bruk
2907 Skolelinux på alle sine skoler. Som tidligere Ballangsværing gledet
2908 det meg stort å se at skoleløsningen vi har utviklet siden
2001 tas i
2909 bruk i området der jeg vokste opp, og dermed bidrar til en bedre og
2910 billigere skolehverdag.
</p
>
2912 <p
>Skolelinux er en komplett IT-løsning for elevnettverket på en
2913 skole, med både nettverkstjenester og løsning for elevmaskiner med
2914 pedagogisk programvare, som tillater en å øke levetiden på en
2915 datamaskin i skolen med mange år. En undersøkelse publisert i mars
2916 2012 viste at de
56 norske skolene som har offentliggjort at de bruker
2917 Skolelinux eller annen Linuxutgave hadde
36% større PC-tetthet enn
2918 landsgjennomsnittet, når en ser på tall rapportert til Grunnskolens
2919 Informasjonssystem. I følge Paul Reidar Løsnesløkken, IKT-konsulent i
2920 Nord-Odal, fungerer datamaskiner godt til de er
8 til
10 år gamle.
</p
>
2922 <p
>I høst (
2012-
09-
29) fortalte Fremover hvordan Ballangen kommune har
2923 opparbeidet seg
20 millioner i underskudd og nok havner på Robek-lista
2924 fra nyttår. Kanskje Ballangen også burde ta i bruk Skolelinux for å
2925 spare penger? Hvis kommunen mangler kompetanse lokalt på Linux finnes
2926 det kommersielle selskaper som tilbyr driftstjenester rundt
2927 Skolelinux, og jeg bør vel avsløre at jeg selv er involvert i et av
2928 dem, Skolelinux Drift AS. Kommunen kan dermed få hjelp hvis de ikke
2929 ønsker å bygge opp egen kompetanse.

3099 Giorgio Pioda, which showed up on the mailing list at the start of
3100 this year, asking questions and inspiring us to improve the first time
3101 administrators experience with Skolelinux. :) The interview was
3102 conduced in May, but I only found time to publish it now.

>I have a PhD in chemistry but since several years I work as teacher
3107 in secondary (
15-
18 year old students) and tertiary (a kind of
"light
"
3108 university) schools. Five years ago I started to manage a Learning
3109 Management Service server and slowly I got more and more involved with
3110 IT.
3 years ago the graduating schools moved completely to Linux and I
3111 got the head of the IT for this. The experience collected in chemistry
3112 labs computers (for example NMR analysis of protein folding) and in
3113 the IT-courses during university where sufficient to start. Self
3114 training is anyway very important

3116 <p
>I live in the Italian speaking part of Switzerland, and the
3117 <a href=

3118 special sport school for young people who try to became sport pro (for
3119 all sports, we have dozens of disciplines represented) and we are

3125 <p
>Looking for Linux / Primary Domain Controller (PDC) I found it
3126 already several years ago. But since the system was still not
3127 Kerberized and since our schools relies strongly on laptops I didn
't
3128 use it. I plan to introduce it in the next future, probably for the
3129 next school year, since the squeeze release solved this security

><strong
>What do you see as the advantages of Skolelinux/Debian
3133 Edu?
</strong
></p
>
3135 <p
>Many. First of all there is a strong and living community that is
3136 very generous for help and hints. Chat help is crucial, together with
3137 the mailing list. Second. With Skolelinux you get an already well
3138 engineered platform and you don
't have to start to build up your PDC
3139 and your clients from GNU/scratch; I
've already done this once and I
3140 can tell it, it is hard. Third, since Skolelinux is a standard
3141 platform, it is way easier to educate other IT people and even if the
3142 head IT is sick another one could pick up the task without too much

3146 Edu?
</strong
></p
>
3148 <p
>The only real problem I see is that it is a little too less
3149 flexible at client level. Debian stable is rocky and desirable, but
3150 there are many reasons that force for another choice. For example the
3151 need of new drivers for new PC, or the need for a specific OS for some
3152 devices that have specific software packages for another specific
3153 distribution (I have such a case for whiteboards that have only
3154 Ubuntu packages). Thus, I prepared compatibility packages educlient
3155 and eduroaming, hoping not to use them ;-)

4 og

3202 vært vellykket.
</p

3204 <p
>Artikkelen med tittelen
"Narvik kommune bruker gratisprogram i
3205 skolen - Har spart millioner
", forteller om hvordan bruken av
3206 Skolelinux er en stor suksess i Narvik siden det ble tatt i bruk i
3207 2004. Her er noen fine sitater:
</p
>
3210 "- Skolelinux har spart kommunen for store pengesummer, millionbeløp,
3211 som de heller kan bruke på andre ting, sier IKT-konsulent Viggo
3215 <p
>Avisen forteller at de har fått tilgang til beregninger som viser
3216 at Narvik kommune har spart noe mellom
10 og
20 millioner kroner de
3217 siste
8 årene på å bruke Skolelinux, og fortsetter:
</p
>
3221 "Regnestykket tar høyde for sparte kostnader til lisenser som medfølger
3222 de alternative operativsystemene, lavere driftskostnader og lengre
3223 levetid på datautstyret. Totalt har Narvikskolen en maskinpark på
3224 1600 maskiner fordelt på de
11 skolene fra Skjomen i sør til Bjerkvik
3229 <p
>Viggo Fedreheim sier dette om hvor noe av gevinsten kommer fra:
</p
>
3232 "- Vi kan gjenbruke gamle maskiner i skolen som er for dårlig andre
3233 steder i kommunen der de ikke bruker Skolelinux. Levetiden på en
3234 datamaskin blir
3-
5 år lenger med Skolelinux. Vi kaller det for
3235 grønn IT, miljøvennlig IT.
"
3238 <p
>Her er det mulighet for flere kommuner å få et godt IT-system på
3239 skolene, hvis de er villige til å forsøke. De som ikke har kompetanse
3240 innomhus kan kjøpe det fra en av de kommersielle leverandørene av

3308 to adjust and scale the just released

3315 <p
>I
'm a
44 year old country guy that have been working
12 years at
3316 the same school as
50% IT-manager and
50% Teacher. My educational
3317 background is fil.kand in history and religious beliefs, an exam as a
3318 "folkhighschool
" teacher, that is, for teaching grownups. In
3319 Norwegian I believe it
's called
"Vuxenupplaring
". I also have a master
3320 in
"Technology and social change
". So I
'm not really a tech guy, I
3321 just like to study how humans and technology interact and that is my
3322 perspective when working with IT.
</p
>
3324 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
3325 project?
</strong
></p
>
3327 I have followed the Skolelinux project for quite some time by
3328 now. Earlier I tested out the K12-LTSP project, which we used for some
3329 time, but I really like the idea of having a distribution aimed to be
3330 a complete solution for schools with necessary tools integrated. When
3331 K12-LTSP abandoned that idea some years ago, I started to look more
3332 seriously into Skolelinux instead.
3334 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
3335 Edu?
</strong
></p
>
3337 The big point of Skolelinux to me is that it is a complete
3338 distribution, ready to install. It has LDAP-support, MS Windows
3339 integration tools and so forth already configured, saving an
3340 administrator a lot of time and headache. We were using another Linux
3341 based thin-client system called Thinlinc, that has served us very
3342 well. But that Skolelinux is based on VNC and LTSP, to me, is better
3343 when it comes to the kind of multimedia used in schools. That is
3344 showing videos from Youtube or educational TV. It is also easier to
3345 mix thin clients with workstations, since the user settings will be the
3346 same. In our VNC-based solution you had to
"beat around the bush
" by
3347 setting up a second, hidden, home-directory for user settings for the
3348 workstations, because they will be different from the ones used on the
3349 thin clients. Skolelinux support for diskless workstations are very
3350 convenient since a school today often need to use a class room
3351 projector showing videos in full screen. That is easily done with a
3352 small integrated media computer running as a diskless workstation. You
3353 have only two installs to update and configure. One for the thin
3354 clients and one for the workstations. Also saving a lot of time. Our
3355 old system was also based on Redhat and CentOS. They are both very
3356 nice distributions, but they are sometimes painfully slow when it
3357 comes to updating multimedia support and multimedia programs (even
3358 such as Gimp), leaving us with a bit
"oldish
" applications. Debian is
3361 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
3362 Edu?
</strong
></p
>
3364 <p
>Debian is a bit too quick when it comes to updating. As an example
3365 we use old HP terminals as thinclients, and two times already this
3366 year (
2012) the updates you get from the repositories has stopped
3367 sound from working with them. It
's a kernel/ALSA issue. So you have
3368 to be more careful properly testing the updates before you run them in
3369 a production environment. This has never happened with CentOS.
</p
>
3371 <p
>I also would like to be able to set my own domain-settings at
3372 install time. In Skolelinux they are kind of hard coded into the
3373 distribution, when it comes to LDAP and at least samba integration.
3374 That is more a cosmetic/translation issue, and not a real problem.
3375 Running MS Windows applications within the Skolelinux environment needs
3376 to be better supported. That is, running them seamlessly via RDP, and
3377 support for single-sign on. That will make the transition to free
3378 software easier, because you can keep the applications you really
3379 need. No support will make it impossible if you work in a school where
3380 some applications can
't be open source. As for us we really need to
3381 run Adobe InDesign in our journalist classes. We run a journalist
3382 education, and is one of the very few non university ones that is ok:d
3383 by Svenska journalistförbundet (Swedish journalist association). Our
3384 education gives the pupils the right of membership there, once they
3385 are done. This is important if you want to get a job.
</p
>
3387 <p
>Adobe InDesign is the program most commonly used in newspapers and
3388 magazines. We used Quark Express before, but they seem to loose there
3389 market to Adobe. The only
"equivalent
" to InDesign in the opensource
3390 world is Scribus, and its not advanced enough. At least not according
3391 to the teacher. I think it would be possible to use it, because they
3392 are not supposed to learn a program, they are supposed to learn how to
3393 edit and compile a newspaper. But politically at our school we are not
3394 there yet. And Scribus lacks a lot of things you find i InDesign.
</p
>
3396 <p
>We used even a windows program for sound editing when it comes to
3397 the radio-journalist part. The year to come we are going to try
3398 Audacity. That software has the same kind of limitations compared to
3399 Adobe Audition, but that teacher is a bit more open minded. We have
3400 tried Ardour also, but that instead is more like a music studio
3401 program, not intended for the kind of editing taking place in a radio
3402 studio. Its way to complex and the GUI is to scattered when you only
3403 want to cut, make pass-overs, add extra channels and normalise. Those
3404 things you can do in Audacity, but its not as easy as in Audition. You
3405 have to do more things manually with envelopes, and that is a bit old
3406 fashion and timewasting. Its also harder to cut and move sound from
3407 one channel to another, which is a thing that you do frequently
3408 because you often find yourself needing to rearrange parts of the
3409 sound file.
</p
>
3411 <p
>So, I am not sure we will succeed in replacing even Audition, but we
3412 will try. The problem is the students have certain expectations when
3413 they start an education towards a profession. So the programs has to
3414 look and feel professional. Good thing with radio, there are many
3415 programs out there, that radio studios use, so its not as standardised
3416 as Newspaper editing. That means, it does not really matter what
3417 program they learn, because once they start working they still have to
3418 learn the program the studio uses, so instead focus has to be to learn
3419 the editing part without to much focus on a specific software.

3421 <p
><strong
>Which free software do you use daily?
</strong
></p
>
3423 <p
>Myself I
'm running Linux Mint, or Ubuntu these days. I use almost
3424 only open source software, and preferably Linux based. When it comes
3425 to most used applications its OpenOffice, and Firefox (of course ;)
3428 <p
><strong
>Which strategy do you believe is the right one to use to
3429 get schools to use free software?
</strong
></p
>
3431 <p
>To get schools to use free software there has to be good open
3432 source software that are windows based, to ease the transition. But
3433 it
's also very important that the multimedia support is working
3434 flawlessly. The problems with Youtube, Twitter, Facebook and whatever
3435 will create problems when it comes to both teachers and
3436 students. Economy are also important for schools, so using thin
3437 clients, as long as they have good multimedia support, is a very good
3438 idea. It
's also important that the open source software works even for
3439 the administration. It
's hard to convince the teachers to stick with
3440 open source, if the principal has to run Windows. It also creates a
3441 problem if some classes has to use Windows for there tasks, since that
3442 will create a difference in
"status
" between classes, so a good
3443 support for running windows applications via the thin client (Linux)
3444 desktop is essential. At least at our school, where we have mixed
3445 level of educations, from high-school to journalist-school.

40 år. Utdannet biolog med ymse
3682 fag på siden. Har jobbet som lærer der jeg var driftsansvarlig på
3683 Ulsrud VGS i Oslo. Senere eide og jobbet jeg flere år i Linuxlabs AS,
3684 som jeg solgte til Redpill Linpro AS (den gangen Linpro AS). I dag
3685 jobber jeg med ulike investeringer, hovedsaklig i eiendom, men også i
3686 en del ulike IT-relaterte bedrifter.

3690 <p
>Fruen og jeg dro på en lengre seiltur i
2000, der jeg måtte ha
"noe
3691 å gjøre
" under hjemturen over Atlanteren. Jeg kjøpte et par bøker om
3692 Linux i en bokhandel i New York og ble veldig fascinert. Etter
3693 hjemkomsten begynte jeg å jobbe på Ulsrud VGS, som naturfagslærer, men
3694 som IT-interessert ble jeg fort en del av den nye IT-satsningen som
3695 skulle løfte Ulsrud og gi skolen en bedre rykte. Vi hadde ganske
3696 mange maskiner, som gikk på Win98 og to servere som ble oppgradert til
3697 Win2000. Systemene var ustabil og dårlige. På leting etter noe
3698 bedre, uten å knekke ryggen økonomisk, kom jeg over
"Linux i Skolen
"
3699 og Skolelinux. Jeg tok kontakt med miljøet og en gjeng møtte opp på
3700 skolen, der vi gjorde en liten testinstallasjon. Etter et par år var
3701 ryggraden på skolen Linux (Skolelinux) og vi hadde flere hundre
3702 maskiner, både tynne klienter (gamle og nye), bærbare (Debian) og noen
3703 stasjonære (Win2000). På et tidspunkt var Ulsrud den råeste IT-skolen
3704 og det irriterte skolesjefen i Oslo, da de satset hardt på

</strong

3709 <p
>Det som gjorde at vi fikk inn Skolelinux var ene og alene
3710 økonomiske. Det faktum at vi slapp å kjøpe masse nye lisenser og at
3711 vi kunne bruke gammel hardware. Alt i alt gjorde dette at vi sparte
3712 mye, men i stede for å bruke mindre på IT brukte vi det vi sparte på å
3713 skaffe mer hardware og på den måten gi det beste tilbudet i landet til
3714 våre elever. For oss som driftet var det himmel å ha et system som
3715 gikk å administrere sentralt og effektivt. Det var heller ikke så
3716 dumt at vi kunne
"låse
" maskinene mer effektivt enn vi kunne med
3717 Microsoft Windows, slik at vi slapp mye feil og problemer som ble
3718 forårsaket av
"kreative
" elever.

3722 <p
>Det vi slet med var mangelen av en del programmer lærerne ville ha.
3723 Husker ikke alle, men det var et knippe med pedagogiske programmer de
3724 ikke fikk. I dag tror jeg det problemet er langt mindre da det meste
3725 av disse kjøres gjennom nettleseren.

3729 <p

3730 både OpenOffice, Firefox og en del andre programmer på den bærbare.
3731 Firefox brukes mest av disse. På Apple-serveren hjemme bruker jeg
3732 HandBrake mye, og jeg har installert OpenWRT på flere av
3733 basestasjonene både hjemme og på jobben. I tillegg til det har jeg i
3734 flere år finansiert et prosjekt som heter
3735 <a href=
"http://www.found.no/
">Found IT
</a

3736 vi lager et rammeverk for søk, der alt vi bruker fri programvare. Det

3740 skoler til å ta i bruk fri programvare?

3742 <p
>Når det gjelder IT og skole er fortsatt økonomi veldig viktig. Så
3743 man må oppfylle minimumskravene (ikke være best, men bra nok) og selge
3744 seg inn på hvor mye man sparer. Det betyr selvsagt at man sparer på
3745 lisenser, men også på driftsinnsats. Men nå når jeg ikke er en aktiv
3746 del av miljøet lenger hører jeg nesten ingen ting om fri programvare.
3747 Jeg stiller meg da spørsmålet om det har blitt stille rundt miljøet,
3748 eller om jeg kun så det tydeligere før når jeg var aktiv? Uansett er
3749 det for stille rundt Skolelinux-prosjektet nå.

've been too busy at home, but finally I found time to wrap up
3759 another interview with the people behind
3760 <a href=
"http://www.skolelinux.org/
">Debian Edu and Skolelinux
</a
>.
3761 This time we get to know José Luis Redrejo Rodríguez, one of our great
3762 helpers from Spain. His effort was the reason we added support for
3763 several desktop types (KDE, Gnome and most recently LXDE) in Debian
3764 Edu, and have all of these available in the recently published
3765 <a href=

3766 Squeeze

</p
>
3768 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
3770 <p
>I
'm a father, teacher and engineer who is working for the Education
3771 ministry of the Region of Extremadura (Spain) in the implementation of
3772 ICT in schools
</p
>
3774 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
3775 project?
</strong
></p
>
3777 <p
>At
2006, I verified that both, we in Extremadura and Skolelinux
3778 project, had been working in parallel for some years, doing very
3779 similar things, using very similar tools and with similar targets, so
3780 I decided it was time to join forces as much as possible.
</p
>
3782 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
3783 Edu?
</strong
></p
>
3785 <p
>A community of highly skilled experts working together, with a
3786 really open schema of collaboration and work. I really love the
3787 concepts of Do-ocracy and Merit-ocracy and the way these concepts are
3788 been used everyday inside Debian Edu.
</p
>
3790 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
3791 Edu?
</strong
></p
>
3793 <p
>Sometimes the differences in the implementations, laws or
3794 economical and technical resources in the different countries don
't
3795 allow us to agree in the same solution for all of us, and several
3796 approaches are needed, what is a waste of effort. Also, there is a
3797 lack of more man power to be able to follow the fast evolution of the
3798 technologies in school.
</p
>
3800 <p
><strong
>Which free software do you use daily?
</strong
></p
>
3802 <p
>Debian, of course, and due to my kind of job I am most of my time
3803 between Iceweasel,
<a href=
"http://www.geany.org/
">Geany
</a
> and
3804 <a href=
"http://www.ohloh.net/p/gnome-terminator
">Terminator
</a
>.
</p
>
3806 <p
><strong
>Which strategy do you believe is the right one to use to
3807 get schools to use free software?
</strong
></p
>
3809 <p
>I think there is not a single strategy because there are very
3810 different scenarios: schools with mixed proprietary and free
3811 environments, schools using only workstations, other schools using
3812 laptops, netbooks, tablets, interactive white-boards, etc.
</p
>
3814 <p
>Also the range of ages of the students is very broad and you can
3815 not use the same solutions for primary schools and secondary or even
3816 universities. So different strategies are needed.
</p
>
3818 <p
>But, looking at these differences, and looking back to the things
3819 we
've done and implemented, and the places were we have spent most of
3820 our forces, I think we should focus as much as possible in free
3821 multi-platform environments, using only standards tools, and moving
3822 more and more to Internet or network solutions that could be deployed
3823 using wireless. I think we
'll see more and more personal devices in
3824 the schools, devices the students and teachers will take home with
3825 them, so the solutions must be able to be taken at home and continue
3826 working there.

">Debian Edu
3837 based on Squeeze
</a
>, I came across some issues that should be
3838 addressed in the Wheezy release. I finally found time to wrap up my
3839 notes and provide quick summary of what I found, with a bit
3840 explanation.
</p
>
3844 <li
>We need to rewrite our package installation framework, as tasksel
3845 changed from using tasksel tasks to using meta packages (aka packages
3846 with dependencies like our education-* packages), and our installation
3847 system depend on tasksel tasks in
3848 /usr/share/tasksel/debian-edu-tasks.desc for package
3849 installation.
</li
>
3851 <li
>Enable Kerberos login for more services. Now with the Kerberos
3852 foundation in place, we should use it to get single sign on with more
3853 services, and avoiding unneeded password / login questions. We should
3854 at least try to enable it for these services:
3857 <li
>CUPS for admins to add/configure printers and users when using
3859 <li
>Nagios for admins checking the system status.
</li
>
3860 <li
>GOsa for admins updating LDAP and users changing their passwords.
</li
>
3861 <li
>LDAP for admins updating LDAP.
</li
>
3862 <li
>Squid for users when exam mode / filtering is active.
</li
>
3863 <li
>ssh for admins and users to save a password prompt.
</li
>
3865 </ul
></li
>
3867 <li
>When we move GOsa to use Kerberos instead of LDAP bind to
3868 authenticate users, we should try to block or at least limit access to
3869 use LDAP bind for authentication, to ensure Kerberos is used when it
3870 is intended, and nothing fall back to using the less safe LDAP bind
</li
>
3872 <li
>Merge debian-edu-config and debian-edu-install. The split made
3873 sense when d-e-install did a lot more, but these days it is just an
3874 inconvenience when we update the debconf preseeding values.
</li
>
3876 <li
>Fix partman-auto to allow us to abort the installation before
3877 touching the disk if the disk is too small. This is
3878 <a href=
"http://bugs.debian.org/
653305">BTS report #
653305</a
> and the
3879 d-i developers are fine with the patch and someone just need to apply
3880 it and upload. After this is done we need to adjust
3881 debian-edu-install to use this new hook.
</li
>
3883 <li
>Adjust to new LTSP framework (boot time config instead of install
3884 time config). LTSP changed its design, and our hooks to install
3885 packages and update the configuration is most likely not going to work
3888 <li
>Consider switching to NBD instead of NFS for LTSP root, to allow
3889 the Kernel to cache files in its normal file cache, possibly speeding
3890 up KDE login on slow networks.
</li
>
3892 <li
>Make it possible to create expired user passwords that need to
3893 change on first login. This is useful when handing out password on
3894 paper, to make sure only the user know the password. This require
3895 fixes to the PAM handling of kdm and gdm.
</li
>
3897 <li
>Make GUI for adding new machines automatically from sitesummary.
3898 The current command line script is not very friendly to people most
3899 familiar with GUIs. This should probably be integrated into GOsa to
3900 have it available where the admin will be looking for it..
</li
>
3902 <li
>We should find way for Nagios to check that the DHCP service
3903 actually is working (as in handling out IP addresses). None of the
3904 Nagios checks I have found so far have been working for me.
</li
>
3906 <li
>We should switch from libpam-nss-ldapd to sssd for all profiles
3907 using LDAP, and not only on for roaming workstations, to have less
3908 packages to configure and consistent setup across all profiles.
</li
>
3910 <li
>We should configure Kerberos to update LDAP and Samba password
3911 when changing password using the Kerberos protocol. The hook was
3912 requested in
<a href=
"http://bugs.debian.org/
588968">BTS report
3913 #
588968</a
> and is now available in Wheezy. We might need to write a
3914 MIT Kerberos plugin in C to get this.
</li
>
3916 <li
>We should clean up the set of applications installed by default.
3919 <li
>reduce the number of chemistry visualisers
</li
>
3920 <li
>consider dropping xpaint
</li
>
3921 <li
>and probably more?
</li
>
3922 </ul
></li
>
3924 <li
>Some hardware need external firmware to work properly. This is
3925 mostly the case for WiFi network cards, but there are some other
3926 examples too. For popular laptops to work out of the box, such
3927 firmware need to be installed from non-free, and we should provide
3928 some GUI to do this. Ubuntu already have this implemented, and we
3929 could consider using their packages. At the moment we have some
3930 command line script to do this (one for the running system, another
3931 for the LTSP chroot).
</li
>
3934 <li
>In Squeeze, we provide KDE, Gnome and LXDE as desktop options. We
3935 should extend the list to Xfce and Sugar, and preferably find a way to
3936 install several and allow the admin or the user to select which one to
3939 <li
>The golearn tool from the goplay package make it easy to check out
3940 interesting educational packages. We should work on the package
3941 tagging in Debian to ensure it represent all the useful educational
3942 packages, and extend the tool to allow it to use packagekit to install
3943 new applications with a simple mouse click.
</li
>
3945 <li
>The Squeeze version got half a exam solution already in place,
3946 with the introduction of iptable based network blocking, but for it to
3947 be a complete exam solution the Squid proxy need to enable
3948 filtering/blocking as well when the exam mode is enabled. We should
3949 implement a way to easily enable this for the schools that want it,
3950 instead of the
"it is documented
" method of today.
</li
>
3952 <li
>A feature used in several schools is the ability for a teacher to
3953 "take over
" the desktop of individual or all computers in the room.
3954 There are at least three implementations,
3955 <a href=
"italc.sourceforge.net/
">italc
</a
>,
3956 <a href=
"http://www.itais.net/help/en/
">controlaula
</a
> og
3957 <a href=
"http://www.epoptes.org/
">epoptes
</a
> and we should pick one of
3958 them and make it trivial to set it up in a school. The challenges is
3959 how to distribute crypto keys and how to group computers in one room
3960 and how to set up which machine/user can control the machines in a
3961 given room.
</li
>
3963 <li
>Tablets and surf boards are getting more and more popular, and we
3964 should look into providing a good solution for integrating these into
3965 the Debian Edu network. Not quite sure how. Perhaps we should
3966 provide a installation profile with better touch screen support for
3967 them, or add some sync services to allow them to exchange
3968 configuration and data with the central server. This should be
3969 investigated.

2010, Mike Gabriel showed up on the
3984 <a href=
"http://www.skolelinux.org/
">Debian Edu and Skolelinux
</a

3985 mailing list. He quickly proved to be a valuable developer, and
3986 thanks to his tireless effort we now have Kerberos integrated into the

>Who are you, and how do you spend your days?
</strong
></p
>
3992 <p
>My name is Mike Gabriel, I am
38 years old and live near Kiel,
3993 Schleswig-Holstein, Germany. I live together with a wonderful partner
3994 (Angela Fuß) and two own children and two bonus children (contributed
3995 by Angela).
</p
>
3997 <p
>During the day I am part-time employed as a system administrator
3998 and part-time working as an IT consultant. The consultancy work
3999 touches free software topics wherever and whenever possible. During
4000 the nights I am a free software developer. In the gaps I also train in
4001 becoming an osteopath.
</p
>
4003 <p
>Starting in
2010 we (Andreas Buchholz, Angela Fuß, Mike Gabriel)
4004 have set up a free software project in the area of Kiel that aims at
4005 introducing free software into schools. The project
's name is
4006 "IT-Zukunft Schule
" (IT future for schools). The project links IT
4007 skills with communication skills.
</p
>
4009 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4010 project?
</strong
></p
>
4012 <p
>While preparing our own customised Linux distribution for
4013 "IT-Zukunft Schule
" we were repeatedly asked if we really wanted to
4014 reinvent the wheel. What schools really need is already available,
4015 people said. From this impulse we started evaluating other Linux
4016 distributions that target being used for school networks.
</p
>
4018 <p
>At the end we short-listed two approaches and compared them: a
4019 commercial Linux distribution developed by a company in Bremen,
4020 Germany, and Skolelinux / Debian Edu. Between
12/
2010 and
03/
2011 we
4021 went to several events and met people being responsible for marketing
4022 and development of either of the distributions. Skolelinux / Debian
4023 Edu was by far much more convincing compared to the other product that
4024 got short-listed beforehand--across the full spectrum. What was most
4025 attractive for me personally: the perspective of collaboration within
4026 the developmental branch of the Debian Edu project itself.
</p
>
4028 <p
>In parallel with this, we talked to many local and not-so-local
4029 people. People teaching at schools, headmasters, politicians, data
4030 protection experts, other IT professionals.
</p
>
4032 <p
>We came to two conclusions:
</p
>
4034 <p
>First, a technical conclusion: What schools need is available in
4035 bits and pieces here and there, and none of the solutions really fit
4036 by
100%. Any school we have seen has a very individual IT setup
4037 whereas most of each school
's requirements could mapped by a standard
4038 IT solution. The requirement to this IT solution is flexibility and
4039 customisability, so that individual adaptations here and there are
4040 possible. In terms of re-distributing and rolling out such a
4041 standardised IT system for schools (a system that is still to some
4042 degree customisable) there is still a lot of work to do here
4043 locally. Debian Edu / Skolelinux has been our choice as the starting
4046 <p
>Second, a holistic conclusion: What schools need does not exist at
4047 all (or we missed it so far). There are several technical solutions
4048 for handling IT at schools that tend to make a good impression. What
4049 has been missing completely here in Germany, though, is the enrolment
4050 of people into using IT and teaching with IT.
"IT-Zukunft Schule
"
4051 tries to provide an approach for this.
</p
>
4053 <p
>Only some schools have some sort of a media concept which explains,
4054 defines and gives guidance on how to use IT in class. Most schools in
4055 Northern Germany do not have an IT service provider, the school
's IT
4056 equipment is managed by one or (if the school is lucky) two (admin)
4057 teachers, most of the workload these admin teachers get done in there
4058 spare time.
</p
>
4060 <p
>We were surprised that only a very few admin teachers were
4061 networked with colleagues from other schools. Basically, every school
4062 here around has its individual approach of providing IT equipment to
4063 teachers and students and the exchange of ideas has been quasi
4064 non-existent until
2010/
2011.
</p
>
4066 <p
>Quite some (non-admin) teachers try to avoid using IT technology in
4067 class as a learning medium completely. Several reasons for this
4068 avoidance do exist.
</p
>
4070 <p
>We discovered that no-one has ever taken a closer look at this
4071 social part of IT management in schools, so far. On our quest journey
4072 for a technical IT solution for schools, we discussed this issue with
4073 several teachers, headmasters, politicians, other IT professionals and
4074 they all confirmed: a holistic approach of considering IT management
4075 at schools, an approach that includes the people in place, will be new
4076 and probably a gain for all.
</p
>
4078 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4079 Edu?
</strong
></p
>
4081 <p
>There is a list of advantages: international context, openness to
4082 any kind of contributions, do-ocracy policy, the closeness to Debian,
4083 the different installation scenarios possible (from stand-alone
4084 workstation to complex multi-server sites), the transparency within
4085 project communication, honest communication within the group of
4086 developers, etc.

4088 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
4089 Edu?
</strong
></p
>
4091 <p
>Every coin has two sides:
</p
>
4093 <p
>Technically:
<a href=
"http://bugs.debian.org/
311188">BTS issue
4094 #
311188</a
>, tricky upgradability of a Debian Edu main server, network
4095 client installations on top of a plain vanilla Debian installation
4096 should become possible sometime in the near future, one could think
4097 about splitting the very complex package debian-edu-config into
4098 several portions (to make it easier for new developers to
4099 contribute).
</p
>
4101 <p
>Another issue I see is that we (as Debian Edu developers) should
4102 find out more about the network of people who do the marketing for
4103 Debian Edu / Skolelinux. There is a very active group in Germany
4104 promoting Skolelinux on the bigger Linux Days within Germany. Are
4105 there other groups like that in other countries? How can we bring
4106 these marketing people together (marketing group A with group B and
4107 all of them with the group of Debian Edu developers)? During the last
4108 meeting of the German Skolelinux group, I got the impression of people
4109 there being rather disconnected from the development department of
4110 Debian Edu / Skolelinux.
</p

4112 <p
><strong
>Which free software do you use daily?
</strong
></p
>
4114 <p
>For my daily business, I do not use commercial software at all.
</p
>
4116 <p
>For normal stuff I use Iceweasel/Firefox, Libreoffice.org. For
4117 serious text writing I prefer LaTeX. I use gimp, inkscape, scribus for
4118 more artistic tasks. I run virtual machines in KVM and Virtualbox.
</p
>
4120 <p
>I am one of the upstream developers of X2Go. In
2010 I started the
4121 development of a Python based X2Go Client, called PyHoca-GUI.
4122 PyHoca-GUI has brought forth a Python X2Go Client API that currently
4123 is being integrated in Ubuntu
's software center.
</p
>
4125 <p
>For communications I have my own Kolab server running using Horde
4126 as web-based groupware client. For IRC I love to use irssi, for Jabber
4127 I have several clients that I use, mostly pidgin, though. I am also
4128 the Debian maintainer of Coccinella, a Jabber-based interactive
4129 whiteboard.

4131 <p
>My favourite terminal emulator is KDE

4155 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
4157 <p
>I am a teacher from Germany, and my subjects are Geography,
4158 Mathematics, and Computer Science (
"Informatik
"). During the past
12
4159 years (since
2000), I have been working for a comprehensive (and soon,
4160 also inclusive) school leading to all kind of general levels, such as
4161 O- or A-level (
"Abitur
"). For quite as long, I
've been taking care of
4162 our computer network.
</p
>
4164 <p
>Now, in my early
40s, I enjoy the privilege of spending a lot of my
4165 spare time together with my wife, our son (
3 years) and our daughter
4166 (
4 months).
</p
>
4168 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4169 project?
</strong
></p
>
4171 <p
>We had tried different Linux based school servers, when members of
4172 my local Linux User Group (LUG OWL) detected Skolelinux. I remember
4173 very well, being part of a party celebrating the Linux New Media Award
4174 (
"Best Newcomer Distribution
", also nominated: Ubuntu) that was given
4175 to Skolelinux at Linux World Exposition in Frankfurt,
2005 (IIRC). Few
4176 months later, I had the chance to join a developer meeting in Ulsrud
4177 (Oslo) and to hand out the award to Knut Yrvin and others. For more
4178 than
7 years, Skolelinux is part of our schools infrastructure, namely
4179 our main server (tjener), one LTSP (today without thin clients), and
4180 approximately
50 work stations. Most of these have the option to boot a
4181 locally installed Skolelinux image. As a consequence, I joined quite
4182 a few events dealing with free software or Linux, and met many Debian
4183 (Edu) developers. All of them seemed quite nice and competent to me,
4184 one more reason to stick to Skolelinux.
</p

4186 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4187 Edu?
</strong
></p
>
4189 <p
>Debian driven, you are given all the advantages of a community
4190 project including well maintained updates. Once, you are familiar with
4191 the network layout, you can easily roll out an entire educational
4192 computer infrastructure, from just one installation media. As only
4193 free software (FOSS) is used, that supports even elderly hardware,
4194 up-sizing your IT equipment is only limited by space (i.e. available
4195 labs). Especially if you run a LTSP thin client server, your
4196 administration costs tend towards zero.
</p
>
4198 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
4199 Edu?
</strong
></p
>
4201 <p
>While Debian
's stability has loads of advantages for servers, this
4202 might be different in some cases for clients: Schools with unlimited
4203 budget might buy new hardware with components that are not yet
4204 supported by Debian stable, or wish to use more recent versions of
4205 office packages or desktop environments. These schools have the
4206 option to run Debian testing or other distributions - if they have the
4207 capacity to do so. Another issue is that Debian release cycles
4208 include a wide range of changes; therefor a high percentage of human
4209 power seems to be absorbed by just keeping the features of Skolelinux
4210 within the new setting of the version to come. During this process,
4211 the cogs of Debian Edu are getting more and more professional,
4212 i.e. harder to understand for novices.
</p

4214 <p
><strong
>Which free software do you use daily?
</strong
></p
>
4216 <p
>LibreOffice, Wikipedia, Openstreetmap, Iceweasel (Mozilla Firefox),
4217 KMail, Gimp, Inkscape - and of course the Linux Kernel (not only on
4218 PC, Laptop, Mobile, but also our SAT receiver)
</p
>
4220 <p
><strong
>Which strategy do you believe is the right one to use to
4221 get schools to use free software?
</strong
></p
>
4225 <li
>Support computer science as regular subject in schools to make
4226 people really
"own
" their hardware, to make them understand the
4227 difference between proprietary software products, and free software
4228 developing.
</li
>
4230 <li
>Make budget baskets corresponding: In Germany
's public schools
4231 there are more or less fixed budgets for IT equipment (including
4232 licenses), so schools won
't benefit from any savings here. This
4233 privilege is left to private schools which have consequently a large
4234 share among German Skolelinux schools.
</li
>
4236 <li
>Get free software in the seminars where would-be teachers are
4237 trained. In many cases, teachers
' software customs are respected by
4238 decision makers rather than the expertise of any IT experts.
</li
>
4240 <li
>Don
't limit ourself to free software run natively. Everybody uses
4241 free software or free licenses (for instance Wikipedia), and this
4242 general concept should get expanded to free educational content to be
4243 shared world wide (school books e.g.).
</li
>
4245 <li
>Make clear where ever you can that the market share of free (libre)
4246 office suites is much above
20 p.c. today, and that you pupils don
't
4247 need to know the
"ribbon menu
" in order to get employed.
</li
>
4249 <li
>Talk about the difference between freeware and free software.
</li
>
4251 <li
>Spread free software, or even collections of portable free apps
4252 for USB pen drives. Endorse students to get a legal copy of
4253 Libreoffice rather than accepting them to use illegal serials. And
4254 keep sending documents in ODF formats.

4279 etter at ryggen sa takk før seg, studerte jeg nettverksadministrasjon
4280 ved Næringsakademiet i Bergen årene

</p
>
4286 <p
>Mitt mål er å bevisstgjøre musikklærene mulighetene med de frie
4287 programmene som finnes i Skolelinux, blant annet Rosegarden.
</p
>
4289 <p
>Har i mange år drevet med musikk og en av grunnen til at Rosegarden
4290 falt i smak for min del, var fordi denne fungere og ligner mest på
4291 Windows-programmet (cubase) jeg jobbet mye med da jeg i mine yngre
4292 dager var «Windows fanatiker». Ble introdusert til Linux av en kompis
4293 av meg for omtrent
14 år siden, og har bare blitt mer og mer glad i
4294 dette operativsystemet.

4298 <p
>Da jeg ble sykemeldt fra min gamle jobb, og måtte omskoleres,
4299 havnet jeg i
2007 sammen med Viggo Fedreheim på IKT-avdelingen i

4301 Skolelinuxprosjektet.
</p
>
4303 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
4305 <p
>Skolelinux er enkelt å holde i drift og masse flotte programmer som
4306 geogebra, ktouch og kgeografi følger med pakken. Man kan ta i bruk
4307 gamle PC-er igjen, slik at skoler med dårlig råd får opp en brukbar
4308 PC-park. PC-er som er ca
6-
9 år gamle fungere tilfredstillende, bare
4309 de har
512 MB RAM eller mer.
</p
>
4311 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
4313 <p
>Ulempene er at noen av de pedagogiske programmene som lærene ønsker
4314 å bruke fungere dårlig med Linux. Mye pga. av at disse programmene
4315 blir ikke laget til Linuxbaserte operativsystemer.
</p
>
4317 <p
>Video- og bilde-redigering har dessverre en del mangler, mange av
4318 programmene har en tendens til og krasje. Det gjelder blant annet
4319 <a href=
"http://www.kdenlive.org/
">kdenlive
</a
> og
4320 <a href=
"http://www.openshotvideo.com/
">openshot
</a
>, for å nevne
4321 noen. De er ikke stabile nok. Når elevene kommer med filmsnutter de
4322 ønsker og jobbe med, så godtar ikke programmene filene, og når elevene
4323 jobber med redigering bare krasjer programmene uten forvarsel. Det er
4324 for vanskelig å få noe som bare fungerer ut av boksen her. Når en elev
4325 plugger inn et videokamera eller fotoapparat så er det alltid noe som
4326 ikke vil fungere. Programmene godtar ikke format, godtar ikke
4327 kameraet, osv., osv. Det er dessverre med på og dra ned en positiv
4328 opplevelse av bruk av fri programvare.
</p
>
4330 <p
>Man må ofte bruke flere en et video redigerings program før og få
4331 fullført en ønsket oppgave.
</p
>
4333 <p
>Eksempel:
</p
>
4335 <p
>Hvis det ene programmet ikke vil ta i mot videofilen klarer et
4336 annet det, men det programmet som klarer det kan ikke gjøre de samme
4337 oppgavene som det programmet som ikke ville ta i mot filen,
4338 Tilsvarende er det med foto, man må bruke flere programmer for å få
4339 et ferdig resultat. Til dags dato har jeg enda ikke funnet et video-
4340 og fotoprogram som kan tilfredstillende fullføre en oppgave.
</p
>
4342 <p
>Så man kan klare og fullføre en oppgave, men i verste fall må man
4343 innom
3-
4 programmer for å få det til. Så jeg har enda ikke til dags
4344 dato sett at et program fungere
100% til alt.
</p
>
4346 <p
>Det programmet jeg har best erfaring til er
4347 <a href=
"http://cinelerra.org/
">cinelerra
</a
>, men dessverre har det
4348 også tendenser og krasje av og til uten grunn.
</p
>
4350 Lydsystemet kan også være et mareritt. Konkret snakker jeg om når du
4351 bruker for eksempel et smartboard, så følger det med USB-lydkort på
4352 disse. Problemet ligger her i at systemet ikke vil velge rett
4353 lydkort, så man må inn med padevchooser for å sette opp PulseAudio
4354 til og velge at USB-lydkortet skal brukes. Det blir for tungvindt for
4355 lærene, de ønsker at ting skal fungere med en gang. (min løsning på
4356 det problemet ble at jeg måtte deaktivere lydkortet som fantes på
4357 maskinen) men da må man bestandig slå på smartboard-tavla.
4359 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p

4361 Programmene jeg bruker mest av er: Rosegarden, jack, qsynth, audacity,
4362 k3b, openttd og libreoffice.

><strong
>Hvilken strategi tror du er den rette å bruke for å få

4367 Jeg tror det må bevisstgjøring av Skolene til, dvs. reklamere høylytt
4368 og fortelle og vise de andre skolene at frie programvarer faktisk
4369 fungere. Jeg trur faktisk mange ikke vet at det finnes frie

4388 <p
>My name is Jürgen Leibner, I
'm
49 years old and living in
4389 Bielefeld, a town in northern Germany. I worked nearly
20 years as
4390 certified engineer in the department for plant design and layout of an
4391 international company for machinery and equipment. Since
2011 I
'm a
4392 certified technical writer (tekom e.V.) and doing technical
4393 documentations for a steam turbine manufacturer. From April this year
4394 I will manage the department of technical documentation at a
4395 manufacturer of automation and assembly line engineering.

4397 <p
>My first contact with linux was around
1993. Since that time I used
4398 it at work and at home repeatedly but not exclusively as I do now at
4399 home since
2006.

4401 <p

>How did you get in contact with the Skolelinux/Debian Edu
4402 project?
</strong
></p

4404 <p
>Once a day in the early year of
2001 when I wanted to fetch my
4405 daughter from primary school, there was a teacher sitting in the
4406 middle of
20 old computers trying to boot them and he failed. I helped
4407 him to get them booting. That was seen by the school director and she
4408 asked me if I would like to manage that the school gets all that old
4409 computers in use. I answered:
"Yes
".
</p
>
4411 <p
>Some weeks later every of the
10 classrooms had one computer
4412 running Windows98. I began to collect old computers and equipment as
4413 gifts and installed the first computer room with a peer-to-peer
4414 network. I did my work at school without being payed in my spare time
4415 and with a lot of fun. About one year later the school was connected
4416 to Internet and a local area network was installed in the school
4417 building. That was the time to have a server and I knew it must be a
4418 Linux server to be able to fulfil all the wishes of the teachers and
4419 being able to do this in a transparent and economic way, without extra
4420 costs for things like licence and software. So I searched for a
4421 school server system running under Linux and I found a couple of
4422 people nearby who founded
'skolelinux.de
'. It was the Skolelinux
4423 prerelease
32 I first tried out for being used at the school. I
4424 managed the IT of that school until the municipal authority took over
4425 the IT management and centralised the services for all schools in
4426 Bielefeld in December of
2006.

4438 <li

4439 they had little money to spent for computers and software.

>It was more able to fit all requirements of a server system for
4445 schools than a Microsoft server system, even if there are only Windows
4446 clients because of it

4460 <li

4463 <li
>They are today mostly managed from central IT departments which
4464 have own concepts which often do not fit to Debian Edu concepts
4465 because they are to close to Microsoft ideology.

4467 <li
>With the Squeeze version of Debian Edu which now uses GOsa² for
4468 management I feel more able to manage the daily tasks than with the

>Da jeg googlet etter noe annet kom jeg tilfeldigvis over
4532 <a href=
"http://www.duo.uio.no/sok/work.html?WORKID=
58309">en
4533 hovedfagsoppgave
</a
> ved Universitetet i Oslo som diskuterer verdien
4534 av GPLs fire friheter for brukerne av IT-systemer. Jeg ble fascinert
4535 over det som presenteres der. Her er sammendraget:
</p
>
4537 <p
><blockquote
>
4539 <p
>Motivasjonen til å skrive denne oppgaven er en personlig undring
4540 over hvorfor det primært, og ofte eksklusivt, fokuseres på det
4541 økonomiske aspektet ved utredninger om fri programvare er et godt valg
4542 for det offentlige. Fri og produsenteid programvare bygger på
4543 fundamentalt forskjellige ideologier som kan ha implikasjoner utover
4544 økonomiske kostnader. Kunnskapskulturen som er med på å definere fri
4545 programvare er basert på åpenhet, og er en verdi i seg selv.
</p
>
4547 <p
>Oppgavens tema er programvarelisensen GPL og frihet. GPL-lisensiert
4548 programvare gir visse friheter i forhold til produsenteid
4549 programvare. Mitt spørsmål er om, og eventuelt i hvilken utstrekning,
4550 disse frihetene blir benyttet av ulike brukere og hvordan de
4551 manifesterer seg for disse brukerne. Sentrale spørsmål i oppgaven
4555 <li
>Hvordan fordeles handlekraft gjennom lisensieringen av programvaren?
</li
>
4556 <li
>Hvilke konsekvenser har programvarelisensen for de ulike brukere?
</li
>
4559 <p
>Fri programvare gir blant annet brukeren mulighet til å studere og
4560 modifisere kildekoden. Denne formen for frihet erverves gjennom
4561 kunnskap og krever at brukeren også er en ekspert. Hva skjer med
4562 frihetene til GPL når sluttbrukeren er en annen? Dette diskuteres i
4563 dialog med informantene.
</p
>
4565 <p
>Jeg har i denne oppgaven samlet inn intervjudata fra IKT-ansvarlige
4566 ved grunnskolene i Nittedal kommune, driftsansvarlig og IKT-veilederen
4567 for skolene i kommunen, samt IKT-koordinator for utdanning i Akershus
4568 fylkeskommune og bokmåloversettere av OpenOffice.org. Den empiriske
4569 delen av oppgaven er delt inn i to seksjoner; den første omhandler
4570 operativsystemet Skolelinux, den andre kontorprogrampakken
4571 OpenOffice.org.
</p
>
4573 <p
>Som vi vil se gir GPL lokal frihet og kontroll gjennom omfordeling
4574 av makt fra produsent til bruker. Brukerens makt analyseres gjennom
4575 begrepene brukermedvirkning og handlingsfrihet. Det blir også lagt
4576 vekt på strukturelle forhold rundt bruken av teknologi, og spesielt de
4577 økonomiske begrepene nettverkseksternaliteter, innlåsing og
4578 stiavhengighet. Dette er begreper av spesiell nytte når objektet som
4579 omsettes eller distribueres er et kommunikasjonsprodukt, fordi verdien
4580 til et slikt gode for en potensiell bruker avhenger av antall
4581 eksisterende brukere av godet. I tilknytning til denne problematikken
4582 inneholder oppgaven også en diskusjon rundt åpne standarder og
4585 <p
>Oppgaven konkluderer med at de «fire frihetene» som GPL-lisensen er
4586 laget for å beskytte er av avgjørende betydning for bruken av
4587 OpenOffice.org og Skolelinux, i Akershus fylkeskommune såvel som i
4588 skolene i Nittedal. Distribusjonen av handlekraft er ikke helt
4589 symmetrisk. Det er først og fremst de profesjonelle utviklerne i
4590 Skolelinux som direkte kan nyttiggjøre seg friheten til å endre kode,
4591 mens en sluttbruker som Nittedal kommune nyttiggjør seg den økonomiske
4592 friheten til å kunne distribuere programmene. Det er imidlertid også
4593 slik at ingen aktør klarer seg uten alle disse «frihetene».

">Debian Edu and
4610 Skolelinux
</a
> there are a lot of people doing the hard work of
4611 setting together all the pieces. This time I present to you Andreas
4612 Mundt, who have been part of the technical development team several
4613 years. He was also a key contributor in getting GOsa and Kerberos set
4614 up in the recently released
4615 <a href=

>Who are you, and how do you spend your days?
</strong
></p
>
4620 <p
>My name is Andreas Mundt, I grew up in south Germany. After
4621 studying Physics I spent several years at university doing research in
4622 Quantum Optics. After that I worked some years in an optics company.
4623 Finally I decided to turn over a new leaf in my life and started
4624 teaching
10 to
19 years old kids at school. I teach math, physics,
4625 information technology and science/technology.
</p
>
4627 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4628 project?
</strong
></p
>
4630 <p
>Already before I switched to teaching, I followed the Debian Edu
4631 project because of my interest in education and Debian. Within the
4632 qualification/training period for the teaching, I started
4633 contributing.
</p
>
4635 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4636 Edu?
</strong
></p
>
4638 <p
>The advantages of Debian Edu are the well known name, the
4639 out-of-the-box philosophy and of course the great free software of the
4640 Debian Project!
</p
>
4642 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
4643 Edu?
</strong
></p
>
4645 <p
>As every coin has two sides, the out-of-the-box philosophy has its
4646 downside, too. In my opinion, it is hard to modify and tweak the
4647 setup, if you need or want that. Further more, it is not easily
4648 possible to upgrade the system to a new release. It takes much too
4649 long after a Debian release to prepare the -Edu release, perhaps
4650 because the number of developers working on the core of the code is
4651 rather small and often busy elsewhere.
</p
>
4653 <p
>The
<a href=
"http://wiki.debian.org/DebianLAN
">Debian LAN
</a
>
4654 project might fill the use case of a more flexible system.
</p
>
4656 <p
><strong
>Which free software do you use daily?
</strong
></p
>
4658 <p
>I am only using non-free software if I am forced to and run Debian
4659 on all my machines. For documents I prefer LaTeX and PGF/TikZ, then
4660 mutt and iceweasel for email respectively web browsing. At school I
4661 have Arduino and Fritzing in use for a micro controller project.
</p
>
4663 <p
><strong
>Which strategy do you believe is the right one to use to
4664 get schools to use free software?
</strong
></p
>
4666 <p
>One of the major problems is the vendor lock-in from top to bottom:
4667 Especially in combination with ignorant government employees and
4668 politicians, this works out great for the
"market-leader
". The school
4669 administration here in Baden-Wuerttemberg is occupied by that vendor.
4670 Documents have to be prepared in non-free, proprietary formats. Even
4671 free browsers do not work for the school administration. Publishers
4672 of school books provide software only for proprietary platforms.
</p
>
4674 <p
>To change this, political work is very important. Parts of the
4675 political spectrum have become aware of the problem in the last years.
4676 However it takes quite some time and courageous politicians to
'free
'
4677 the system. There is currently some discussion about
"Open Data
" and
4678 "Free/Open Standards
". I am not sure if all the involved parties have
4679 a clue about the potential of these ideas, and probably only a
4680 fraction takes them seriously. However it might slowly make free
4681 software and the philosophy behind it more known and popular.

</a

4749 up a
<a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>
4750 Lenny installation using LTSP diskless workstations, and in the
4751 process I discovered something very surprising. The reason the KDE
4752 menu was responding slow when using it for the first time, was mostly
4753 due to the way KDE find application icons. I discovered that showing
4754 the Multimedia menu would cause more than
20 000 IP packages to be
4755 passed between the LTSP client and the NFS server. Most of these were
4757 NFS LOOKUP calls, resulting in a NFS3ERR_NOENT response. Because the
4758 ping times between the client and the server were in the range
2-
20
4759 ms, the menus would be very slow. Looking at the strace of kicker in
4760 Lenny (or plasma-desktop i Squeeze - same problem there), I see that
4761 the source of these NFS calls are access(
2) system calls for
4762 non-existing files. KDE can do hundreds of access(
2) calls to find
4763 one icon file. In my example, just finding the mplayer icon required
4764 around
230 access(
2) calls.
</p
>
4766 <p
>The KDE code seem to search for icons using a list of icon
4767 directories, and the list of possible directories is large. In
4768 (almost) each directory, it look for files ending in .png, .svgz, .svg
4769 and .xpm. The result is a very slow KDE menu when /usr/ is NFS
4770 mounted. Showing a single sub menu may result in thousands of NFS
4771 requests. I am not the first one to discover this. I found a
4772 <a href=
"https://bugs.kde.org/show_bug.cgi?id=
211416">KDE bug report
4773 from
2009</a
> about this problem, and it is still unsolved.
</p
>
4775 <p
>My solution to speed up the KDE menu was to create a package
4776 kde-icon-cache that upon installation will look at all .desktop files
4777 used to generate the KDE menu, find their icons, search the icon paths
4778 for the file that KDE will end up finding at run time, and copying the
4779 icon file to /var/lib/kde-icon-cache/. Finally, I add symlinks to
4780 these icon files in one of the first directories where KDE will look
4781 for them. This cut down the number of file accesses required to find
4782 one icon from several hundred to less than
5, and make the KDE menu
4783 almost instantaneous. I
'm not quite sure where to make the package
4784 publicly available, so for now it is only available on request.
</p
>
4786 <p
>The bug report mention that this do not only affect the KDE menu
4787 and icon handling, but also the login process. Not quite sure how to
4788 speed up that part without replacing NFS with for example NBD, and
4789 that is not really an option at the moment.

>Germany is a core area for the
4817 <a href=

">Debian Edu and Skolelinux
</a
>
4818 user community, and this time I managed to get hold of Wolfgang
4819 Schweer, a valuable contributor to the project from Germany.
4821 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
4823 <p
>I
've studied Mathematics at the university
'Ruhr-Universität
' in
4824 Bochum, Germany. Since
1981 I
'm working as a teacher at the school
4825 "<a href=
"http://www.westfalenkolleg-dortmund.de/
">Westfalen-Kolleg
4826 Dortmund
</a
>", a second chance school. Here, young adults is given
4827 the opportunity to get further education in order to do the school
4828 examination
'Abitur
', which will allow to study at a university. This
4829 second chance is of value for those who want a better job perspective
4830 or failed to get a higher school examination being teens.
</p
>
4832 <p
>Besides teaching I was involved in developing online courses for a
4833 blended learning project called
'abitur-online.nrw
' and in some other
4834 information technology related projects. For about ten years I
've been
4835 teacher and coordinator for the
'abitur-online
' project at my
4836 school. Being now in my early sixties, I
've decided to leave school at
4837 the end of April this year.
</p
>
4839 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4840 project?
</strong
></p
>
4842 <p
>The first information about Skolelinux must have come to my
4843 attention years ago and somehow related to LTSP (Linux Terminal Server
4844 Project). At school, we had set up a network at the beginning of
1997
4845 using Suse Linux on the desktop, replacing a Novell network. Since
4846 2002, we used old machines from the city council of Dortmund as thin
4847 clients (LTSP, later Ubuntu/Lessdisks) cause new hardware was out of
4848 reach. At home I
'm using Debian since years and - subscribed to the
4849 Debian news letter - heard from time to time about Skolelinux. About
4850 two years ago I proposed to replace the (somehow undocumented and only
4851 known to me) system at school by a well known Debian based system:
4852 Skolelinux.
</p
>
4854 <p
>Students and teachers appreciated the new system because of a
4855 better look and feel and an enhanced access to local media on thin
4856 clients. The possibility to alter and/or reset passwords using a GUI
4857 was welcomed, too. Being able to do administrative tasks using a GUI
4858 and to easily set up workstations using PXE was of very high value for
4859 the admin teachers.
</p
>
4861 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4862 Edu?
</strong
></p
>
4864 <p
>It
's open source, easy to set up, stable and flexible due to it
's
4865 Debian base. It integrates LTSP out-of-the-box. And it is documented!
4866 So it was a perfect choice.
</p
>
4868 <p
>Being open source, there are no license problems and so it
's
4869 possible to point teachers and students to programs like
4870 OpenOffice.org, ViewYourMind (mind mapping) and The Gimp. It
's of
4871 high value to be able to adapt parts of the system to special needs of
4872 a school and to choose where to get support for this.
</p
>
4874 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
4875 Edu?
</strong
></p
>
4877 <p
>Nothing yet.
</p
>
4879 <p
><strong
>Which free software do you use daily?
</strong
></p
>
4881 <p
>At home (Debian Sid with Gnome Desktop): Iceweasel, LibreOffice,
4882 Mutt, Gedit, Document Viewer, Midnight Commander, flpsed (PDF
4883 Annotator). At school (Skolelinux Lenny): Iceweasel, Gedit,
4884 LibreOffice.
</p
>
4886 <p
><strong
>Which strategy do you believe is the right one to use to
4887 get schools to use free software?
</strong
></p
>
4889 <p
>Some time ago I thought it was enough to tell people about it. But
4890 that doesn
't seem to work quite well. Now I concentrate on those more
4891 interested and hope to get multiplicators that way.

4901 sendt ut følgende pressemelding basert på mine beregninger av

4909 <p
>Det er store forskjeller på skolenes digitale tilstand, viser
4910 undersøkelsen Monitor
2011 som er laget på oppdrag fra
4911 Kunnskapsdepartementet. Dette har ført til debatt om PC-tilgangen i
4912 skolen, og om de med Linux i skolen gjør det bedre bedre eller
4913 dårligere enn snittet i landet.
</p
>
4915 <p
>Nå har vi tallene. Skoler med Linux har
36% større PC-tetthet en
4916 landsgjennomsnittet. På spørsmål hvorfor skoler med Linux har større
4917 PC-tetthet, observerer Paul Reidar Løsnesløkken som er IKT-konsulent i
4918 Nord-Odal:
</p
>
4920 <p
><blockquote
>"Vi erfarer at klienter med Skolelinux har god funksjon
4921 til de er
8 til
10 år gamle. Dette er omtrent dobbelt så lenge som
4922 andre løsninger, og skolene får mer datautstyr for
4923 pengene.
"</blockquote
></p
>
4925 <p
>Undersøkelsen baserer seg på
56 skoler som har gjort det offentlig
4926 at de kjører Skolelinux eller annen Linux-utgave. De kan også ha PC-er
4927 med Windows i skolenettet. Når en sammenligner PC-tetthetene på
4928 skolene i kommunene Flora, Harstad, Kongsvinger, Narvik, Nittedal,
4929 Nord-Odal og Randaberg, er det i snitt
2,
28 elev pr. PC på skolene med
4930 Linux. På landsbasis er det
3.11 elev per PC i grunnskolen, i følge
4931 side
95 i Monitor-rapporten for
2011. Målingen viser dermed
36% større
4932 PC-tetthet i skoler med Linux.

4936 <p
>Skolelinux har til hensikt å gi alle barn full tilgang til
4937 skoleaktuelle dataprogram på sitt eget morsmål. Derfor følger det med
4938 godt over
100 skoleaktuelle programmene laget for læring. De fleste
4939 programmene er oversatt til over
50 språk. Elevene skal også kunne
4940 studere alle sider av dataprogrammene. Derfor følger også kildekode
4941 med. Elever med interesse kan lære av eksperter som har laget
4942 systemet. Dette med enkelt programmering i læreprogram som KTurtle,
4943 til profesjonelle verktøy som Qt Creator eller Java.
</p
>
4945 <p
>Skolelinux er laget for sentralisert drift, der alt teknisk
4946 administrasjon av alle skolene kan gjøres sentralt fra kommunehuset
4947 eller sentralt i en region. F.eks. drifter to-tre personer
70.000
4948 skoledatamaskiner på
200 skoler i delstaten Extremadura i
4949 Spania. Etter velykket bruk av Debian Edu i skolen, legger delstaten
4950 over til Debian på
40.000 datamaskiner i administrasjonen. Det er idag
4951 mange selskap som tilbyr profesjonell støtte til innføring og drift i
4952 Norge og verden.

4989 <description><p
>I serien med intervjuer av folk i
4990 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet, får vi
4991 denne gangen høre fra en IKT-ansvarlig som har brukt Skolelinux i
4992 mange år, og vært storfornøyd med erfaringene så langt.
</p
>
4994 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
4996 <p
>Mitt navn er Roy-Arne Myhre og jeg er
42 år. Jeg er ansatt hos
4997 <a href=
"http://www.sandskole.no/
">Sand skole
</a
> (Balsfjord kommune)
4998 og har stort sett vært det siden
1990. Jeg er IKT ansvarlig ved
4999 skolen i
40% stilling –
10% undervisning – musikk.
</p
>
5001 <p
>Ved skolen er det ca
100 elever og ca
18 lærere +
4 assistenter i
5002 hele og delte stillinger. Alle lærerne har bærbar PC (dessverre med
5003 Win Vista) – assistenter har tilgang til egne. Vi benytter Fronter i
5004 det daglige arbeidet. Vi har ca
90 elevmaskiner som fungerer til
5005 daglig opp mot Linux server (XFCE) som driftes av
5006 <a href=
"http://www.bzz.no/
">BzzWare AS
</a
> via nett. Maskinparken
5007 består kun av brukt utstyr for elevene – og noe av dette begynner å
5008 bli vel gammelt selv som halvtykke klienter.
</p
>
5010 <p
><strong
>Hvordan kom du i kontakt med
5011 Skolelinux-prosjektet?
</strong
></p
>
5013 <p
>Vi kom første gang i kontakt med Skolelinux rundt
1997. Den gang
5014 var det oppstart-disketter i hver maskin, ikke mulighet for lyd og
5015 video, gamle nettverkskort og mye plundring. Vi hadde en ihuga
5016 forelder med som pådriver, forsker og inspirator for hele opplegget.
5017 Selv ante jeg knapt at Skolelinux fantes, men han var av den
5018 utforskende typen, og fikk både meg og skolelederen i trua på at dette
5019 var ting som kunne fungere. Etter dette har det gått gradvis
5020 framover; flere maskiner er hentet inn gjennom bl.a
5021 <a href=
"http://www.greentech.no/
">Greentech
</a
> og utrangert utstyr
5022 fra høgskole / Avinor og private givere. Når maskinene ble for trege
5023 for nye Windows-versjoner, sto vi klare til å putte dem i nettverket
5024 vårt. Dette betyr at vi i dag har
1:
1 dekning av maskiner på
5025 ungdomstrinnet og bedre enn
1:
2 på barnetrinnet. Dette er vi veldig
5026 fornøyd med, og vi kan ikke se for oss hverdagen som ville vært
5027 alternativet ved bruk av Windows med sine lisenser pr. Bruker/maskin.
5028 Da ville vi nok vært tilbake til
1-
2 maskiner pr klasserom med de
5029 negative konsekvenser det ville hatt for undervisningsformene våre. Vi
5030 kan ha en hel klasse i prosjektjobbing eller individuell jobbing
5031 samtidig – vi kan avholde tentamen og eksamen uten
5032 logistikkproblemer.
</p
>
5034 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
5036 Hvor skal jeg begynne... Stabiliteten er et nøkkelord - det bare
5037 virker. Har du først fått en server med Skolelinux opp og gå, så må
5038 det en maskinarefeil eller sabotasje til for å stoppe den. Det at man
5039 kan bruke eldre maskiner som normalt sett ville gått på dynga, er også
5040 glimrende - billig for skoler med dårlig økonomi og bra for miljøet
5041 siden vi gjenbruker utstyr i stedet for å skaffe nytt. Vi ville aldri
5042 hatt mulighet til å operere med det maskinantallet vi har pr i dag
5043 hvis det ikke var for Skolelinux - så tilgjengelighet er et annet
5044 nøkkelord. Et tredje moment er sikkerhet og brukertilgang. Alle
5045 brukerer opererer med egne brukernavn og passord, samt egne
5046 brukerområder som kan tilpasses for både enbrukertilgang og for
5047 samarbeid med andre.
5049 Elever har godt av å se at det finnes andre alternativer enn de som
5050 storindustrien selger på lisensbasis - på den måten trenes de opp til
5051 å se flere muligheter og å foreta valg ut fra flere opsjoner.
5053 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
5055 <p
>Ulempene med Skolelinux er nok utbredelsen og mangelen på kjennskap
5056 til dette i skolenorge. De som skal ta økonomiske avgjørelser rynker
5057 på nesen og vil gå for det kjente og «sikre» selv om det koster mye
5058 mer. Man får rett og slett litt hetta av å ikke kunne noe – og unngår
5059 dette for enhver pris.
</p
>
5061 <p
>I tillegg er mye av linux-systemet administrert av tekstkommandoer
5062 og er lite intuitiv/visuell for oss som ikke er «inne i»
5063 kildekodene». Så problemet er nok mye godt at de som
5064 utarbeider/drifter Skolelinux ikke helt klarer å sette seg ned på
5065 skoleadministratorens nivå når det gjelder problemer og
5066 utfordringer. Men dette er nok en utfordring alle administratorer
5067 sliter med uansett OS.
</p
>
5069 <p
>Derfor har vi valgt å støtte oss til BzzWare AS for assistanse i
5070 drifta slik at jeg har kunnet konsentrere meg mer om kabling, skifting
5071 av komponenter, veiledning av lærere og elever, vedlikehold av
5072 skrivere og annen daglig drift.
</p
>
5074 <p
>Elevene mestrer Skolelinux helt fint. Så lenge Internett
5075 (Iceweasel) og Libreoffice (Openoffice) fungerer er
90% av
5076 skolehverdagen velfungerende. I tillegg brukes jo en del av den
5077 pedagogiske programpakken bla. i forhold til matematikk og geografi,
5078 men det er såpass mye bra på nett om dagen, så disse programmene er
5079 mer som krydder å regne.
</p
>
5081 <p
>Jeg skulle ønske neste versjon av Skolelinux kunne komme litt
5082 mindre stappet med programmer, for halvparten blir aldri brukt, eller
5083 fungerer ikke uansett. Hva med et pedagogisk panel av lærere/IKT
5084 ansvarlige som kunne sagt: disse programmene skal være standard, så
5085 får resten være slike man kan legge til ved behov – det kan lett bli
5086 en jungel å bevege seg i.
</p
>
5088 <p
>Jeg ønsker meg også en mer grafisk versjon av
5089 <a href=
"http://bzz.no/lwat/trac/trac.cgi
">Lwat
</a
> hvor man kan krysse
5090 ut de som f.eks ikke skal ha internett-tilgang en dag pga
5091 eksamen/tentamen, samt en noe enklere brannmurløsning hvor man kan
5092 stenge for en del (få) sider på en enkel måte. Jeg liker godt
5093 Skolelinux sin ideologi om at filteret skal trenes i hodet på eleven –
5094 men av og til skulle jeg ønske at f.eks Facebook og Youtube kunne vært
5095 koblet vekk en periode for å få bedre utnyttelse av tid og
5096 ressurser. Disse to nettstedene er nok mye av årsaken til at mange
5097 lærere holder igjen databruken noe mer enn man kunne ønske.
</p
>
5099 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
5101 Jeg benytter nesten bare fri programvare til daglig. LibreOffice,
5102 Iceweasel (Firefox), Thunderbird til e-post og Gimp til
5103 bildebehandling. Vi har PHP-Nuke-oppsatt hjemmeside. Det eneste som
5104 jeg ikke har fått helt til enda er videoredigering - her må man vel
5105 innrømme at Mac er hakket over, men da er vi igjen over på å se hva
5106 som egner seg best, og ta valg ut fra det. Folk flest lever i
5107 villfarelsen om at regneark HETER Excel og tekstbehandling HETER
5108 Word. Dette er en misforståelse som jeg bruker mye energi på å
5109 diskutere og
"åpne sinn
" på Microsoft-slaver. Dessverre er det mange
5110 IKT-ansvarlige som også har låst seg på at det eneste saliggjørende er
5111 Bill G sine produkter.
5113 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
5114 skoler til å ta i bruk fri programvare?
</strong
></p
>
5116 <p
>For å komme lenger i utbredelsen av Skolelinux tror jeg det må mer
5117 fram i nasjonale medier, samt komme bedre fram hva økonomien i dette
5118 valget vil være – samt mulighetene. Fri programvare er en berikelse og
5119 gjør oss i stand til å utføre arbeidet i skolen uten å måtte legge
5120 igjen tusener på tusener i Bill Gates lomme.. Få ETT nettsted med
5121 forståelig veiledning av installasjon/oppgradering og ETT forum med
5122 konkrete feilrettinger og problemer, så tror jeg vi kunne kommet et
5123 par skritt framover. Ellers tror jeg bare at ildsjelene må fortsette å
5124 skinne – kanskje flere enn oss følger etter på veien.

5162 i Digi
</a

5163 Linux-skoler har større PC-tettet enn snittet i landet. Grunnlaget
5164 for diskusjonen har vært undersøkelsen

5168 (GSI). GSI-data kan lastes ned fra web og jeg lastet ned en Excel-fil
5169 (intet åpen standard-valg tilgjengelig) med navn på alle skoler,
5170 hvilke kommune de befinner seg i og hvor mange elever pr. elev-PC de
5171 har rapportert inn. For å få en ide om svaret trenger jeg deretter å
5172 vite hvilke skoler i landet som bruker Linux, slik at jeg kan slå dem
5173 opp i GSI og finne ut hvor stor PC-tetthet de har.
</p

5175 <p
>Jeg vet om skoler i Balsfjord, Flora, Harstad, Kongsvinger, Narvik,
5176 Nittedal, Nord-Odal, Randaberg og Sunndal som bruker Skolelinux eller
5177 andre Linux-varianter. Jeg tror det er flere enn de
56 skolene jeg
5178 har klart å identifisere de siste dagene, men har ikke klart å få det
5179 bekreftet med offentlige kilder.
</p

5181 <p
>Monitor
2011-rapporteres side
95 forteller at det
"ifølge GSI
5182 (
20120-
2011) er det
3,
11 elever per datamaskin når vi tar med alle
5183 grunnskoler (
1.-
10.trinn)
". For de
56 Linux-skolene jeg har klart å
5184 koble mot informasjon i GSI er det
2,
28 elever per elevdatamaskin,
5185 hvilket betyr at det er
36% høyere PC-tetthet på Linux-skoler enn
5186 landsgjennomsnittet. Linux-skolen med høyest tettet blant de jeg har
5187 notert -skole er Flora ungdomsskule i Flora kommune med
0.82 elev
5188 pr. PC (
482 elever,
588 elevdatamaskiner).
</p
>
5190 <p
>Skolelinux gir datamaskiner lengre levetid, og en kan dermed få
5191 flere operative datamaskiner for samme budsjett, i tillegg til en
5192 rekke andre fordeler. Kan det være forklaringen på forskjellen?
</p
>
5194 <p
>Tallene må tas med en liten klype, da GSI ser ut til å ha endel
5195 feilføringer. Jeg synes i hvert fall en skole med
423 elever og
9
5196 elevmaskiner ser mistenkelig ut. Eller en skole med
346 elever,
0
5197 elevmaskiner, som er et annet ekstremt eksempel jeg fant.

>Who are you, and how do you spend your days?
</strong
></p
>
5217 <p
>I teach ICT part time at the Rudolf Steiner School in Kings
5218 Langley, near London, UK. Previously I worked as a technical
5219 author/trainer while my children attended the school, and I also
5220 contributed to the Schoolforge UK community with the aim of
5221 encouraging UK schools to adopt free/open source software. Five or six
5222 years ago we had about
50 schools interested in some way, but we
5223 weren
't able to convert many of them into sustainable
5224 installations.
</p
>
5226 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5227 project?
</strong
></p
>
5229 <p
>Skolelinux had two representatives at an early Edubuntu meeting in
5230 London which I attended. However at that time our school network had
5231 just been installed using CentOS, LTSP
4 and GNOME. When LTSP
5 came
5232 along we switched to Edubuntu thin client servers so now we have a
5233 mixed environment which includes Windows PCs and student laptops, as
5234 well as their MacBooks and iPads. However, the proprietary systems
5235 have always been rather problematic, and we never built a GUI for the
5236 LDAP server, so when I discovered Skolelinux is configured for all
5237 these things we decided to try it.
</p

5239 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5240 Edu?
</strong
></p
>
5242 <p
>By far the biggest advantage is the Debian Edu community. Apart
5243 from that I have always believed in the same
"sustainable computing
"
5244 goals that Skolelinux is built on: installing Linux on computers which
5245 would otherwise be thrown away, to provide a reliable, secure and
5246 low-cost IT environment for schools. From my own experience I know
5247 that a part-time person can teach and manage a network of about
25
5248 Linux computers, but it would take much more of my time if we had
5249 proprietary software everywhere.

5254 <p
>As a newcomer I
'm just finding out who
's who in the community and
5255 how you
're organised, and what your procedures are for dealing with
5256 various things such as editing manual pages and so-on. The only
5257 English language mailing list seems to be for developers as well as
5258 users, so my inbox needs heavy pruning each day!

5260 <p
><strong
>Which free software do you use daily?
</strong
></p

5262 <p
>Besides the software already mentioned at school we use Samba,
5263 OpenLDAP, CUPS, Nagios and Dansguardian for the network, and on the
5264 desktops we have LibreOffice, Firefox, GIMP and Inkscape. At home I
5265 use Ubuntu and an Android
4 eePad Transformer (but I
'm not sure if
5266 that counts...)
</p
>
5268 <p
><strong
>Which strategy do you believe is the right one to use to
5269 get schools to use free software?
</strong
></p
>
5271 <p
>That
's a tough question! For very many years UK schools installed
5272 and taught only proprietary software, so that at the highest levels
5273 the notion of
"computer
" means simply
"proprietary office
5274 applications
". However, schools today are experiencing budget
5275 constraints, and many are having to think hard about upgrading Windows
5276 XP. At the same time, we have students showing teachers how to use
5277 iPads, MacBooks and Android, so the choice of operating system is no
5278 longer quite so automatic. What is more, our government at last
5279 realised that we need people with programming skills, so they
're
5280 putting coding back in the curriculum! And it
's encouraging that the
5281 first
10,
000 Raspberry Pi units sold out in
2 hours.
</p
>
5283 <p
>I don
't really know what strategy is going to get UK schools to use
5284 free software, but building an active community of Skolelinux/Debian
5285 Edu users in this country has to be part of it.

>Documentation in Debian Edu is provided in several languages, and
5295 it is important to make it both easy to contribute and to keep the
5296 translated versions in sync. To do this we have come up with what we
5297 believe is a very efficient work flow.
</p
>
5301 <li
>The documentation is written in a
5302 <a href=
"http://moinmo.in
">moinmoin wiki
</a
> (see for example
5303 <a href=
"http://wiki.debian.org/DebianEdu/Documentation/Squeeze
">the
5304 Squeeze release manual
</a
>) with support for exporting the content as
5305 docbook XML.
</li
>
5307 <li
>This docbook document is given to po4a to extract a gettext style
5308 .pot file with the content, which in turn is used to create .po files
5309 with the translated text.
</li
>
5311 <li
>The .po files are given to translators, and they can always tell
5312 which part of the original wiki document is new or changed. They can
5313 use their normal translation tools like lokalize or poedit to write
5314 the translation. There is even a system in place to handle translated
5317 <li
>The translated .po files are combined with the original docbook
5318 XML document using po4a to create a translated docbook document.
</li
>
5320 <li
>The final step is to use all the generated docbook files and
5321 create PDF and HTML version of the original and translated documents.
</li
>
5325 <p
>This setup work very well, but have a few issues. The biggest
5326 issue is that
<a href=
"http://moinmo.in/DocBook
">the docbook support
5327 we use in moinmoin
</a
> is not actively maintained. The docbook
5328 support is also buggy, and our build system contain workarounds to
5329 make sure the generated docbook is usable despite these bugs.
</p

5388 <p
>Jeg hørte om det først når jeg jobbet i Redpill Linpro. Men jeg
5389 har også en datter som går på en friskole, som også bruker Skolelinux.
5390 Som kjent har ikke friskoler de samme økonomiske rammebetingelsene som
5391 offentlige skoler, så for dem var det det absolutt beste alternativet.
5392 De anser også Skolelinux som et stabilt system, som bare går og går (i

5398 <p

5399 lydløse og raskere arbeidsstasjoner som er bedre i klasserommet.
5400 Lengre levetid på PC

5401 så klart fjerning av alle lisenskostnader. Personlig synes jeg også at
5402 mange av programmene er bedre enn alternativene. Men dette er ofte en

5408 kompatibilitet med arbeidsstasjoners/bærbare maskiner sine
5409 nettverksdrivere eller skjermkort. Men dette løser vi i skolene ved
5410 standardisering. Ellers er det få, om nesten ingen, av de kjente
5411 maskinvare / infrastruktur leverandørene til fylkes- / kommuner som
5412 tilbyr denne plattformen. Skal dette endre seg så må kommunene selv
5413 sette slike krav til leverandørene.

5417 <p
>Har brukt OpenOffice.org siden starten (

2005. Bruker i dag Kubuntu, Libreoffice og ymse annet
5419 programvare til ulik kontorbruk som er lett å installere / teste via

></p
>
5425 <p
>Fortsette å presentere flere av de gode eksemplene hvor Debian Edu
5426 / Skolelinux brukes i kommuner og enkeltskoler. Vi må få bedre frem
5427 at det er mulig tilknytte både Windows og Mac klienter på denne
5428 plattformen (selv om det vil øke driftskostnadene). Dette gjøres
5429 mange steder. Spesielt er det mange lærere som ønsker å bruke
5430 Windows/Mac-bærbare, gjerne som sin private PC også. Det er også mulig
5431 for kommunen å integrere med Active Directory i stedet for OpenLDAP
5432 som kommer med ut av boksen (selv om også dette øker kostnadene).
5433 Dette vil muligens bidra til å fjerne noe motstand hos noen
5434 potensielle brukere / driftpersonell for å ta i bruk noe
5435 nytt. Fremveksten av mobile brukere og nettbrett går i vår favør.
5436 Brukerne blir kjent og vant til flere nye operativsystemer /
5437 brukergrensesnitt. Så utviklerfellesskapet bør jobbe videre med å
5438 integrere flere nye klienttyper, som ultra lav-kostklienter og
5439 nettbrett (blant annet fri programvare-alternativet

5472 interview series with people involved in the Debian Edu / Skolelinux
5473 community. This was so popular that I believe it is time to move to a
5474 more international audience.

<a href=
"http://www.skolelinux.org/

5477 Skolelinux
</a

5478 Europe, there are users all around the globe. One of those far away
5479 from me is Nigel Barker, a long time Debian Edu system administrator
5480 and contributor. It is thanks to him that Debian Edu is adjusted to
5481 work out of the box in Japan. I got him to answer a few questions,
5482 and am happy to share the response with you. :)
5485 <p
><strong
>Who are you, and how do you spend your days?
</strong

5487 <p
>My name is Nigel Barker, and I am British. I am married to Yumiko,
5488 and we have three lovely children, aged
15,
14 and
4(!) I am the IT
5489 Coordinator at Hiroshima International School, Japan. I am also a
5490 teacher, and in fact I spend most of my day teaching Mathematics,
5491 Science, IT, and Chemistry. I was originally a Chemistry teacher, but
5492 I have always had an interest in computers. Another teacher teaches
5493 primary school IT, but apart from that I am the only computer person,
5494 so that means I am the network manager, technician and webmaster,
5495 also, and I help people with their computer problems. I teach python
5496 to beginners in an after-school club. I am way too busy, so I really
5497 appreciate the simplicity of Skolelinux.

5499 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5500 project?
</strong
></p
>
5502 <p
>In around
2004 or
5 I discovered the ltsp project, and set up a
5503 server in the IT lab. I wanted some way to connect it to our central
5504 samba server, which I was also quite poor at configuring. I discovered
5505 Edubuntu when it came out, but it didn
't really improve my setup. I
5506 did various desperate searches for things like
"school Linux server
"
5507 and ended up in a document called
"Drift
" something or other. Reading
5508 there it became clear that Skolelinux was going to solve all my
5509 problems in one go. I was very excited, but apprehensive, because my
5510 previous attempts to install Debian had ended in failure (I used
5511 Mandrake for everything - ltsp, samba, apache, mail, ns...). I
5512 downloaded a beta version, had some problems, so subscribed to the
5513 Debian Edu list for help. I have remained subscribed ever since, and
5514 my school has run a Skolelinux network since Sarge.

5519 <p
>For me the integrated setup. This is not just the server, or the
5520 workstation, or the ltsp. Its all of them, and its all configured
5521 ready to go. I read somewhere in the early documentation that it is
5522 designed to be setup and managed by the Maths or Science teacher, who
5523 doesn
't necessarily know much about computers, in a small Norwegian
5524 school. That describes me perfectly if you replace Norway with

5531 have fun themes for children, or with distributions such as Mint, who
5532 make the desktop beautiful. They create a good impression on people
5533 who don
't need to understand how to use any of it, but who might be
5534 important to the school. School administrators or directors, for
5535 instance, or parents. Even kids. Debian itself usually has ugly
5536 default theme settings. It was my dream a few years back that some
5537 kind of integration would allow Edubuntu to do the desktop stuff and
5538 Debian Edu the servers, but now I realise how impossible that is. A
5539 second disadvantage is that if something goes wrong, or you need to
5540 customise something, then suddenly the level of expertise required
5541 multiplies. For example, backup wasn
't working properly in Lenny. It
5542 took me ages to learn how to set up my own server to do rsync backups.

>Nowadays I only use Debian on my personal computers. I have one for
5549 studio work (I play guitar and write songs), running AV Linux
5550 (customised Debian) a netbook running Squeeze, and a bigger laptop
5551 still running Skolelinux Lenny workstation. I have a Tjener in my
5552 house, that
's very useful for the family photos and music. At school
5553 the students only use Skolelinux. (Some teachers and the office still
5554 have windows). So that means we only use free software all day every
5555 day. Open office, The GIMP, Firefox/Iceweasel, VLC and Audacity are
5556 installed on every computer in school, irrespective of OS. We also
5557 have Koha on Debian for the library, and Apache, Moodle, b2evolution
5558 and Etomite on Debian for the www. The firewall is Untangle.

5563 <p
>Current trends are in our favour. Open source is big in industry,
5564 and ordinary people have heard of it. The spread of Android and the
5565 popularity of Apple have helped to weaken the impression that you have
5566 to have Microsoft on everything. People complain to me much less about
5567 file formats and Word than they did
5 years ago. The Edu aspect is
5568 also a selling point. This is all customised for schools. Where is the
5569 Windows-edu, or the Mac-edu? But of course the main attraction is
5570 budget.The trick is to convince people that the quality is not
5571 compromised when you stop paying and use free software instead. That
5572 is one reason why I say the desktop experience is a weakness. People
5573 are not impressed when their USB drive doesn
't work, or their browser
5574 doesn
't play flash, for example.

>Many years ago, the
<a href=
"http://www.skolelinux.org/
">Skolelinux
5621 / Debian Edu project
</a
> initiated a student project to create a tool
5622 for making stop motion movies. The proposal came from a teacher
5623 needing such tool on Skolelinux. The project, called
"stopmotion
",
5624 was manned by two extraordinary students and won a school award and a
5625 national aware with this great project. The project was initiated and
5626 mentored by Herman Robak, and manned by the students Bjørn Erik Nilsen
5627 and Fredrik Berg Kjølstad. They got in touch with people at Aardman
5628 Animation studio and received feedback on how professionals would like
5629 such stopmotion tool to work, and the end result was and is used by
5630 animators around the globe. But as is usual after studying, both got
5631 jobs and went elsewhere, and did not have time to properly tend to the
5632 project, and it has been lingering for a few years now. Until last
5635 <p
>Last year some of the users got together with Herman, and moved the
5636 project to Sourceforge and in effect restarted the project under a new
5638 <a href=
"http://sourceforge.net/projects/linuxstopmotion/
">linuxstopmotion
</a
>.
5639 The name change was done to make it possible to find the project using
5640 Internet search engines (try to search for
'stopmotion
' to see what I
5641 mean). I
've been following
5642 <a href=
"https://lists.sourceforge.net/lists/listinfo/linuxstopmotion-community
">the
5643 mailing list
</a

5644 the future is encouraging. If you want to make stop motion movies.

>Knut Yrvin her. Jobber i Nokia med å fremme rammeverket Qt og QML
5722 med tilhørende utviklerverktøy. Rollen er som leder av
5723 friprog-samfunn. I fjor var jeg med å legge om utviklingen av Qt til
5724 åpen forvaltning. På den måten kan alle som bidrar til Qt gjøre det
5725 på like vilkår. Nå er det
5726 <a href=

">over
5727 1000 utviklere
</a
> som bidrar til Qt. Med overgangen til åpen
5728 forvaltning er utviklingen av Qt mer åpen enn Linux-kjernen.
</p
>
5730 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
5732 <p
>Jeg var en av initiativtagerne til Skolelinux i
2001. Skolene slet
5733 med både utstyr og Internett-tilgang. De klarte ikke å møte
5734 forventningene til data i skolen. Driften av PC-ene var uholdbar. Som
5735 regel hadde rektor pekt ut en ivrig lærer til å passe på PC-ene,
5736 gjerne naturfaglæreren. Mange lærere jobbet mye ubetalt overtid for å
5737 vedlikeholde
30-
40 datamaskiner på hver sin skole. Med
300 elever og
5738 lærere som brukere, blir det fort mye mer arbeid enn de
4-
8 timene de
5739 kunne bruke på PC-drift. Skolene hadde kun en femtedel av
5740 IT-budsjettet som ble brukt på PC-ene i rådhuset.
</p
>
5742 <p
>Vi erfarte at skolene hadde mye datautstyr som stod ubrukt. Skolene
5743 manglet penger til Microsoft-lisenser. Selv med solide skolerabatter,
5744 kostet Microsoft-lisensene gjerne like mye som PC-ene i seg selv over
5745 en periode på
5-
6 år.
</p
>
5747 <p
>Viktigheten av språklig mangfold og pedagogiske programmer var også
5748 viktig for oss. Vi oversatte mange skoleaktuelle programmer til
5749 nynorsk, nordsamisk og bokmål. Dette lenge før andre tok denne
5750 oppgaven seriøst. Allerede etter ett år hadde vi etablert et helt
5751 arsenal av skoleaktuelle programmer på nynorsk, bokmål og
5752 nordsamisk. Vi spredde vår ide om språklig mangfold til de andre frie
5753 prosjekter internasjonalt. Resultatene ser vi i mange land. Det er de
5754 frie programmene som kommer på brukernes morsmål. Det er en av flere
5755 gode grunner til at fri programvare som LibreOffice, VLC, KDE og
5756 Firefox konkurrerer ut godseid programvare mange steder i verden.
</p
>
5758 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
5760 <p
>Fordelene er at Skolelinux tilbyr over
100 skoleaktuelle programmer
5761 på de norske språkene, uten ett øre i lisenskostnader. Systemet gir
5762 enormt lave driftskostnader med diskløse arbeidsstasjoner og bærbare
5763 med roaming. Skolelinux krever også mindre av maskinvaren.
</p
>
5765 <p
>Man kan fint kjøre systemet med
512 MB RAM på en bærbar PC sammen
5766 med en nettvideo i nettleseren og en presentasjon med
5767 LibreOffice. Konkurrerende system krever fort
2 GB RAM for å få til
5768 noe tilsvarende uten at det går ufattelig tregt. Skal man gjøre noe
5769 nyttig, krever konkurrentene til Linux mye større harddisk. Skoler har
5770 rapportert at de fort har fått
50% flere nye maskiner om de velger
5771 Linux. Dette i tillegg til de årlige besparelsene ved å unngå
5772 lisensbetaling til godseid programvare.
</p
>
5774 <p
>De lave driftskostnadene gjør at delstater i Europa har titusener
5775 av datamaskiner med Skolelinux i skolen. F.eks. er det under ti
5776 personer som drifter
70.000 PC-systemer i skolene i Extremadura i
5777 Spania. Det er slett ikke uvanlig at norske kommuner har
1500-
2000
5778 datamaskiner med Skolelinux. Driften tar ett årsverk. Slår flere
5779 kommuner seg sammen, kan de få samme sentraliserte stordriftsfordeler
5780 som delstater i Tyskland og Spania. Delstater som kjører Skolelinux
5781 på alle skolene. Bare noen få personer sentraldrifter titusenvis av
5784 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
5786 <p
>Den største ulempen for Skolelinux er motstand mot Linux fra
5787 IT-sjefer i det offentlige. Dette er ledere som holder innlegg som
5788 snytt ut av evangelist-håndboka til Microsoft. Dette gjøres i ett
5789 arbeidsmarked med stor vekst i etterspørselen etter Linux-fagfolk i
5790 privat sektor. Etterspørselen har økt mer enn noe annet tekniske yrke
5791 siste tiåret. Åtte av ti ledere vil ansette Linux-fagfolk i
2012,
5792 rapporterer jobbnettstedet Dice.com på oppdrag av Linux
5793 Foundation.
</p
>
5795 <p
>Det mangler
16.000 ingeniører og IKT-fagfolk i Norge rapporterte
5796 arbeids- og velferdsetaten NAV. Linux-fagfolk kan velge svært
5797 interessante jobber med alt fra apps på ledende mobilsystem laget med
5798 Linux, sky- tjenester eller web-applikasjoner. De raskest voksende
5799 teknologiselskapene i verden er ute etter Linux-fagfolk. Det være seg
5800 Amazon, Google, Facebook og IBM for å nevne noen. Linux er kritisk
5801 for å sikre veksten i markedet. Det sier seg selv at lønningene og
5802 jobbmulighetene er bedre enn for andre tekniske yrker.
</p
>
5804 <p
>Skal man lage apps for mobilen, smart-TV-en eller
5805 underholdningssystemet i bilen eller på flyet, er det Linux som
5806 gjelder. Med en slik konkurranse om Linux-kompetansen, kombinert med
5807 motstanden mot Linux hos mange IT-sjefer i offentlig sektor, så
5808 hindrer kommunene rekruttering av flere Linux- fagfolk. Skolene blir
5809 tvunget til å velge dyrere og mindre komplette IT-system. De har
5810 blitt hengende igjen slik IT var på begynnelsen av
2000- tallet. Dette
5811 fordi IT-ledere ikke har tilpasset seg markedet det siste tiåret.
</p
>
5813 <p
>Når det er sagt, er Skolelinux svært enkelt å lære seg også for de
5814 som ikke kan. Det viser alle lærerne som drifter systemet for
5815 hundrevis og tusenvis av systemer. Det meste er på plass rett ut av
5816 boksen. I tillegg er det solid med dokumentasjon med god hjelp på
5817 nettet. Det er mange kommuner som har ansatt en lærer som først lærte
5818 Skolelinux på sin skole, for så å drifte alle PC-ene i kommunen med
5819 Skolelinux. Det kan fort være snakk om
1000-
3000 datamaskiner på
10-
15
5820 skoler som sentraldriftes med en stilling. Står man ordentlig fast,
5821 kan man også kjøpe profesjonell hjelp fra selskap som støtter
5822 Skolelinux. Det er flere slike selskap i Norge og i utlandet.

5826 <p
>Qt SDK, LibreOffice, Firefox, VLC og KDE-skrivebordet. Dette på et
5827 Debian-basert GNU/Linux-system. Jeg bruker også noen morsomme
5828 3D-spill. Idag kan jeg velge mellom over
30.000 Linux-programmer. Det
5829 finnes ikke tid i livet å undersøke alle valgmulighetene. Derfor er
5830 det bra med Skolelinux i skolen, da utvalget av programmer er
5831 begrenset til hva som er aktuelt i skolefagene.
</p

5833 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
5834 skoler til å ta i bruk fri programvare?
</strong
></p

5836 <p
>Vi må selge hele Skolelinux forhåndsinstallert på maskinvare i hele
5837 pakker med
50-
100-
1000 PC-klienter med servere. Dette kan selges til
5838 enkeltskoler eller hele kommuner. Pakken må inneholde tjenermaskiner,
5839 svært rimelige diskløse arbeidsstasjoner, nettbrett med Plasma Active,
5840 og bærbare med roaming. Alt er godt testet med Debian. I et slikt
5841 anbud er det mulig å legge til sentraliserte drifts- og
5842 støttetjenester.
</p
>
5844 <p
>Man bør også selge sky-tjenester som læreadministrative systemet
5845 Moodle og driftsovervåking. I tillegg så bør man slenge seg på med
5846 presentasjoner de gangene LibreOffice og andre friprog-produkter
5847 selges til kommuner.

5939 <description><p
>New in the Squeeze version of
5940 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> is the
5941 ability for clients to automatically configure their proxy settings
5942 based on their environment. We want all systems on the client to use
5943 the WPAD based proxy definition fetched from
<tt
>http://wpad/wpad.dat
</tt
>, to
5944 allow sites to control the proxy setting from a central place and make
5945 sure clients do not have hard coded proxy settings. The schools can
5946 change the global proxy setting by editing
5947 <tt
>tjener:/etc/debian-edu/www/wpad.dat
</tt
> and the change propagate
5948 to all Debian Edu clients in the network.
</p
>
5950 <p
>The problem is that some systems do not understand the WPAD system.
5951 In other words, how do one get from a WPAD file like this (this is a
5952 simple one, they can run arbitrary code):
</p

5954 <blockquote

5955 function FindProxyForURL(url, host)
5957 if (!isResolvable(host) ||
5958 isPlainHostName(host) ||
5959 dnsDomainIs(host,
".intern
"))
5960 return
"DIRECT
";
5962 return
"PROXY webcache:
3128; DIRECT
";
5964 </pre

5966 <p
>to a proxy setting in the process environment looking like this:
</p
>
5968 <blockquote
><pre
>
5969 http_proxy=http://webcache:
3128/
5970 ftp_proxy=http://webcache:
3128/
5971 </pre
></blockquote
>
5973 <p
>To do this conversion I developed a perl script that will execute
5974 the javascript fragment in the WPAD file and return the proxy that
5976 <tt
><a href=
"http://www.debian.org/
">http://www.debian.org/
</a
></tt
>,
5977 and insert this extracted proxy URL in
<tt
>/etc/environment
</tt
> and
5978 <tt
>/etc/apt/apt.conf
</tt
>. The perl script wpad-extract work just
5979 fine in Squeeze, but in Wheezy the library it need to run the
5980 javascript code is
<a href=
"http://bugs.debian.org/
631045">no longer
5981 able to build
</a
> because the C library it depended on is now a C++
5982 library. I hope someone find a solution to that problem before Wheezy
5983 is frozen. An alternative would be for us to rewrite wpad-extract to
5984 use some other javascript library currently working in Wheezy, but no
5985 known alternative is known at the moment.
</p
>
5987 <p
>This automatic proxy system allow the roaming workstation (aka
5988 laptop) setup in Debian Edu/Squeeze to use the proxy when the laptop
5989 is connected to the backbone network in a Debian Edu setup, and to
5990 automatically use any proxy present and announced using the WPAD
5991 feature when it is connected to other networks. And if no proxy is
5992 announced, direct connections will be used instead.
</p
>
5994 <p
>Silently using a proxy announced on the network might be a privacy
5995 or security problem. But those controlling DHCP and DNS on a network
5996 could just as easily set up a transparent proxy, and force all HTTP
5997 and FTP connections to use a proxy anyway, so I consider that
5998 distinction to be academic. If you are afraid of using the wrong
5999 proxy, you should avoid connecting to the network in question in the
6000 first place. In Debian Edu, the proxy setup is updated using dhcp and
6001 ifupdown hooks, to make sure the configuration is updated every time
6002 the network setup changes.
</p
>
6004 <p
>The WPAD system is documented in a
6005 <a href=

6036 med brukte jeg først Mandrake og så Debian. Og siden jeg oppdaget at

6055 jeg bruker Kubuntu er nok at da vi begynte med det mener jeg det ikke
6056 var noen annen løsning. «Vandrende arbeidsstasjon» mener jeg ikke
6057 fantes da. Dessuten ville jeg ha siste versjon, da den KDE-versjonen
6058 som var i Skolelinux den gangen var en god del enklere (tror det var

>Since the Lenny version of
6099 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>, a
6100 feature to save power have been included. It is as simple as it is
6101 practical: Shut down unused clients at night, and turn them on again
6102 in the morning. This is done using the
6103 <a href=
"http://packages.qa.debian.org/s/shutdown-at-night.html
">shutdown-at-night
</a
> Debian package.
</p
>
6105 <p
>To enable this feature on a client, the machine need to be added to
6106 the netgroup shutdown-at-night-hosts. For Debian Edu, this is done in
6107 LDAP, and once this is in place, the machine in question will check
6108 every hour from
16:
00 until
06:
00 to see if the machine is unused, and
6109 shut it down if it is. If the hardware in question is supported by
6111 <a href=
"http://packages.qa.debian.org/n/nvram-wakeup.html
">nvram-wakeup
</a
>
6112 package, the BIOS is told to turn the machine back on around
07:
00 +-
6113 10 minutes. If this isn
't working, one can configure wake-on-lan to
6114 try to turn on the client. The wake-on-lan option is only documented
6115 and not enabled by default in Debian Edu.
</p
>
6117 <p
>It is important to not turn all machines on at once, as this can
6118 blow a fuse if several computers are connected to the same fuse like
6119 the common setup for a classroom. The nvram-wakeup method only work
6120 for machines with a functioning hardware/BIOS clock. I
've seen old
6121 machines where the BIOS battery were dead and the hardware clock were
6122 starting from
0 (or was it
1990?) every boot. If you have one of
6123 those, you have to turn on the computer manually.
</p
>
6125 <p
>The shutdown-at-night package is completely self contained, and can
6126 also be used outside the Debian Edu environment. For those without a
6127 central LDAP server with netgroups, one can instead touch the file
6128 <tt
>/etc/shutdown-at-night/shutdown-at-night
</tt
> to enable it.
6129 Perhaps you too can use it to save some power?

6161 disabled queues are restarted every hour. This should cut down on
6162 the amount of manual administration needed for printers.

6164 <li
>The set of initial users have been changed. Now a personal user
6165 for the local system administrator is created during installation
6166 instead of the previously created localadmin and super-admin users,
6167 and this user is granted administrative privileges using group
6168 membership. This reduces the number of passwords one need to keep
6169 up to date on the system.

>With some computer hardware, one need non-free firmware blobs.
6192 This is the sad fact of todays computers. In the next version of
6193 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> based
6194 on Squeeze, we provide several scripts and modifications to make
6195 firmware blobs easier to handle. The common use case I run into is a
6196 laptop with a wireless network card requiring non-free firmware to
6197 work, but there are other use cases as well.
</p
>
6199 <p
>First and foremost, Debian Edu provide ISO images for DVD and CD
6200 with all firmware packages in the Debian sections main and non-free
6201 included, to ensure debian-installer find and can install all of them
6202 during installation. This take care firmware for network devices used
6203 by the installer when installing from from local media. But for
6204 example multimedia devices are not activated in the installer and are
6205 not taken care of by this.
</p
>
6207 <p
>For non-network devices, we provide the script
6208 <tt
>/usr/share/debian-edu-config/tools/auto-addfirmware
</tt
> which
6209 search through the
<tt
>dmesg
</tt
> output for drivers requesting extra
6210 firmware. The firmware file name is looked up in the Contents-ARCH.gz
6211 file available in the package repository, and the packages providing
6212 the requested firmware file(s) is installed. I have proposed to do
6213 something similar in debian-installer (BTS report
6214 <a href=
"http://bugs.debian.org/
655507">#
655507</a
>), to allow PXE
6215 installs of Debian to handle firmware installation better. Run the
6216 script as root from the command line to fetch and install the needed
6217 firmware packages.
</p
>
6219 <p
>Debian Edu provide PXE installation of Debian out of the box, and
6220 because some machines need firmware to get their network cards
6221 working, the installation initrd some times need extra firmware
6222 included to be able to install at all. To fill the PXE installation
6223 initrd with extra firmware, the
6224 <tt
>/usr/share/debian-edu-config/tools/pxe-addfirmware
</tt
> script is
6225 provided. Again, just run it as root on the command line to fill the
6226 PXE initrd with firmware packages.
</p
>
6228 <p
>Last, some LTSP clients might also need firmware to get their
6229 network cards working. For this,
6230 <tt
>/usr/share/debian-edu-config/tools/ltsp-addfirmware
</tt
> is
6231 provided to update the LTSP initrd with firmware blobs. It is used
6232 the same way as the other firmware related tools.
</p
>
6234 <p
>At the moment, we do not run any of these during installation. We
6235 do not know if this is acceptable for the local administrator to use
6236 non-free software, and it is their choice.

6294 <description><p
>The next version of
<a href=
"http://www.skolelinux.org/
">Debian Edu
6295 / Skolelinux
</a
> will include a new tool
6296 <tt
>sitesummary2ldapdhcp
</tt
>, which can be used to quickly set up all
6297 the computers in a school without much manual labour. Here is a short
6298 summary on how to use it to set up a new school.
</p
>
6300 <p
>First, install a combined Main Server and Thin Client Server as the
6301 central server in the network. Next, PXE boot all the client machines
6302 as thin clients and wait
5 minutes after the last client booted to
6303 allow the clients to report their existence to the central server. When
6304 this is done, log on to the central server and run
6305 <tt
>sitesummary2ldapdhcp -a
</tt
> in the
<tt
>konsole
</tt
> to use the
6306 collected information to generate system objects in LDAP. The output
6307 will look similar to this:
</p
>
6309 <p
><blockquote
><pre
>
6310 % sitesummary2ldapdhcp -a
6311 info: Updating machine tjener.intern [
10.0.2.2] id ether-

6314 Enter password if you want to activate these changes, and ^c to abort.
6316 Connecting to LDAP as cn=admin,ou=ldap-access,dc=skole,dc=skolelinux,dc=no
6317 enter password: *******
6319 </pre
></blockquote
></p
>
6321 <p
>After providing the LDAP administrative password (the same as the
6322 root password set during installation), the LDAP database will be
6323 populated with system objects for each PXE booted machine with
6324 automatically generated names. The final step to set up the school is
6325 then to log into
<a href=
"https://oss.gonicus.de/labs/gosa/
">GOsa
</a
>,
6326 the web based user, group and system administration system to change
6327 system names, add systems to the correct host groups and finally
6328 enable DHCP and DNS for the systems. All clients that should be used
6329 as diskless workstations should be added to the workstation-hosts
6330 group. After this is done, all computers can be booted again via PXE
6331 and get their assigned names and group based configuration
6332 automatically.
</p
>
6334 <p
>We plan to release beta3 with the updated version of this feature
6335 enabled this weekend. You might want to give it a try.
</p
>
6337 <p
>Update
2012-
01-
28: When calling sitesummary2ldapdhcp to add new
6338 hosts, one need to add the option -a. I forgot to mention this in my
6339 original text, and have added it to the text now.

6348 <description><p
>I serien med intervjuer av folk i
6349 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet, har jeg nå
6350 lyktes med å få tak i en skolemann som ikke er aktiv med utviklingen,
6351 men likevel har vært med nesten siden starten av prosjektet. Jeg
6352 ønsker derfor velkommen til Paul Reidar Løsnesløkken, en mann med
6353 mange års erfaring i bruk av Skolelinux.
</p
>
6355 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
6357 <p
>Jeg driftet tidligere IKT løsningen for skolene i
6358 <a href=
"http://www.nord-odal.kommune.no/
">Nord-Odal
</a
>. I dag er jeg
6359 IKT-konsulent for hele kommunen og samarbeider med
6360 <a href=
"http://www.hedmarken-ikt.no/
">Hedmark-IKT
</a
> for best mulig
6361 tjenester til kommunen. Jeg har bakgrunn som elektronikkreparatør og
6362 grunnskolelærer og har tatt en del fag innen IKT, i hovedsak
6363 driftsfag. IKT i Nord-Odal kommune blir i dag driftet av Hedmark IKT
6364 som er et samarbeid mellom Løten, Stange, Grue, Hamar, Kongsvinger og
6365 Nord-Odal. Jeg er fortsatt
"IKT-personen
" på skolene i kommunen og
6366 følger opp og gjør enkelte mindre endringer der.
</p
>
6368 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
6370 <p
>Kommunen satset på Skolelinux i
2004. Jeg var ikke med i
6371 beslutningsprosessen den gang, men ble likevel med fra starten når
6372 dette ble levert.
</p
>
6374 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6376 <p
>Fordelene med Skolelinux er rask oppstart, sentral drift av
6377 klientene, klienter som jobber raskt og effektivt, bedre
6378 funksjonalitet på eldre utstyr og en ganske god programpakke med fri
6379 programvare som følger med. Løsningen med halvtykke klienter gjør at
6380 prosessering skjer lokalt med alltid ferske maskiner.
</p
>
6382 <p
>Skolelinux kan fungere godt på gammelt utstyr, men det er klart at
6383 utstyr også blir for gammelt selv for Skolelinux. I forbindelese med
6384 at vi nylig fikk nye servere og ny installasjon kastet jeg ut ca
60
6385 klienter som fortsatt var i drift etter at de var kjøpt godt brukt i
6386 2004. Noe var rundt
15 år gammelt, men var fortsatt i bruk. Noen
6387 klaget på at det nå gikk veldig tregt på en del pedagogiske nettsider
6388 med flash o.l. Det er fullt forståelig.
</p
>
6390 <p
>Jeg fikk nylig et spørsmål fra ungdomsskolens rektor om jeg kunne
6391 legge inn
<a href=
"http://freemind.sourceforge.net/
">FreeMind
</a
>, et
6392 tankekartprogram , på skolens elev-Windowsmaskiner. Lærerne hadde
6393 vært på kurs og ville ta dette i bruk. Skolen har ca halvparten av
6394 elevmaskinene på bærbare Windowsmaskiner. Da kunne jeg fortelle at
6395 dette programmet allerede lå inne på den nye Skolelinuxløsningen
6396 som nettopp var satt i drift, klart til bruk.
</p
>
6398 <p
>Vi har de bærbare maskinene på ungdomsskolen i domene med
6399 Skolelinux. Dette fungerer også meget bra nå. Elevene får opp en
6400 midlertidig windowsprofil når de logger på. Denne profilen slettes
6401 etter at de logger av, noe som medfører rene profiler hver gang de
6402 starter opp en maskin. De må lagre i sin Skolelinprofil, noe som
6403 medfører at de får tak i sine filer uavhengig av om de starter en
6404 Windowsmaskin eller en Skolelinuxklient. Det er mye mindre trafikk i
6405 det trådløse nettet etter at ikke hele profiler blir lastet opp til de
6406 enkelte Windowsmaskinene og tilbake når man avslutter. Jeg vet ikke om
6407 dette er standardoppsett i Skolelinux, men slik er vårt oppsett
6410 <p
>Vi har i flere år satt opp vår løsning slik at skriverkøer slettes
6411 og skrivere startes hver natt. Hyggelig å høre at dette nå skal bli
6412 en standard i Skolelinuxløsningen. Dette har vært en god hjelp for
6415 <p
>Elevene er lite opptatt av om de jobber på en Skolelinux eller en
6416 Windowsmaskin bare de har de programmene de trenger og at det virker
6417 når det skal brukes. Vi kjører mest mulig de samme programmene på
6418 Windows som i Skolelinux, som f.eks Audacity og LibreOffice.
</p
>
6420 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6422 <p
>Lærere bruker hos oss Windows. Dette fordi de da selv har mer
6423 kontroll over sin maskin, kan bruke den overalt, og kan legge inn
6424 programmer selv når de trenger noe i forhold til kurs o.l de er
6425 på. Jeg tror lærernes selvstendighet her gjør dem tryggere på IKT-bruk
6426 generelt. Det at de av og til får opp advarsler og lignende gjør også
6427 at de må tenke igjennom og spørre om ting rundt datasikkerhet.
</p
>
6429 <p
>Det er en del programmer vi bruker som ikke finnes for Linux. Mest
6430 brukt er nok Photostory3 som brukes i mange sammenhenger, særlig på
6431 ungdomsskolen, bl.a. til å lage herbarier (plantesamling) . Dette
6432 finnes gratis for Windows, men er ikke fri programvare. Vi er opptatt
6433 av at programmer elevene bruker på skolen også kan brukes gratis
6434 hjemme. Det er også en del programmer som brukes til spesielle elever
6435 som bare går i Windows. Det er viktig med fokus på funksjoner og ikke
6436 på hvilket OS man bruker.
</p
>
6438 <p
>For oss er det kombinasjonen mellom Skolelinux og Windows som gir
6439 oss en god og hel løsning. Skolelinux er best der de er gode.
</p
>
6441 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
6443 <p
>Selv er det LibreOffice jeg bruker til daglig. Jeg bruker selv en
6444 Windowsmaskin. Jeg har benyttet en del fri programvare i forbindelse
6445 med sjekking av trafikk i nettverk, slik som Wireshark, men dette er
6446 jo ikke aktuelt for skolene. Jeg er generelt glad i programmer som
6447 fungerer på både Linux og Windows og gjerne MAC.
</p
>
6449 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
6450 skoler til å ta i bruk fri programvare?
</strong
></p
>
6452 <p
>Det er viktig at det benyttes programmer som elevene også kan ta i
6453 bruk hjemme. Det skal da være enkelt, lovlig og gratis for
6454 elevene. Da er jeg ikke lenger veldig opptatt av om det kalles
"fri
6455 programvare
". For skolene tror jeg
"gratis
" og
"funksjonelt
" er bedre
6456 begreper enn
"fri
" i forhold til programmer. De fleste skiller nok
6457 ikke mellom
"fri
" og
"gratis
". Det er nå svært mange elever som
6458 benytter OpenOffice eller LibreOffice som sin primære kontorpakke

6470 to be released, users of the system will get their default browser
6471 start page set from LDAP, allowing the system administrator to point
6472 all users to the school web page by updating one setting in LDAP. In
6473 addition to setting the default start page when a machine boots, users
6474 are shown the same page as a welcome page when they log in for the
6475 first time.
</p

6477 <p
>The LDAP object dc=skole,dc=skolelinux,dc=no have an attribute
6478 labeledURI with
"http://www/ LDAP for Debian Edu/Skolelinux

6479 default content. By changing this value to another URL, all users get
6480 to see the page behind this new URL.

6482 <p
>An easy way to update it is by using the ldapvi tool. It can be
6483 called as
"<tt

6484 new setting.
</p

6486 <p

6487 the welcome page, and I wonder if there is an easier way to do this
6488 from within Iceweasel instead.

>During christmas, I have been working getting the next version of
6515 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> ready
6516 for release. The initial problem I looked at was particularly
6517 interesting.
</p
>
6519 <P
>The installer would hang at the end when it was doing it
6520 post-installation configuration, and whatevery I did to try to find
6521 the cause and fix it always worked while I tested it, but never when I
6522 integrated it into the installer and ran the installation from
6523 scratch. I would try to restart processes, close file descriptors,
6524 remove or create files, and the installer would always unblock and
6525 wrap up its tasks.
</p
>
6527 <p
>Eventually the cause was found. The kernel was simply running out
6528 of entropy, causing the Kerberos setup to hang waiting for more.
6529 Pressing keys was adding entropy to the kernel, and thus all my tries
6530 to fix the problem worked not because what I was typing to fix it, but
6531 because I was typing.
</P
>
6533 <p
>The fix I implemented was to add a background process looking at
6534 the level of entropy in the kernel (by checking
6535 /proc/sys/kernel/random/entropy_avail), and if it was too small, the
6536 installer will flush the kernel file buffers and do
'find /
' to
6537 generate some disk IO. Disk IO generate entropy in the kernel, and is
6538 one of the few things that can be initated from within the system to
6539 generate entropy.

6541 <p
>The fix is in
6542 <a href=

>Etter en lang pause er det klart for neste mann ut i min serie med
6556 <a href=

">Skolelinux
</a

6558 Denne gangen har jeg besøk av et avtroppende styremedlem i
6559 <a href=
"http://www.friprogramvareiskolen.no/
">FRISK
</a

6560 som har vært aktiv i Linux-miljøet i Bergen siden
90-tallet.
</p

6562 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
6564 <p
>Jeg heter Peter Hansteen, og jobber til daglig som seniorkonsulent
6565 i EDB ErgoGroup i Bergen. I praksis betyr det systemadministrasjon på
6566 Unix (primært Solaris, men en viss komponent av Linux). Men Solaris
6567 er for meg et relativt nytt bekjentskap, hovedplattformen min har
6568 generelt vært OpenBSD og til dels FreeBSD.
</p

6570 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
6572 <p
>Jeg husker ikke helt alle detaljene mer ;) - men jeg tror det var
6573 gjennom news-gruppen no.it.os.unix.linux.diverse, efn-listen og
6574 etterhvert også BLUG-miljøet her i Bergen. Vi hadde et par
6575 Skolelinux-sentrerte BLUG-møter for noen år siden, og det har vært et
6576 par Skolelinux-utviklersamlinger her.
</p
>
6578 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6580 <p
>Jeg bruker dessverre ikke Skolelinux daglig. Men slik jeg kjenner
6581 prosjektet har det vært i stand til å ta opp i seg det beste av fri
6582 programvare i mange kategorier, så fra et sysadmin-perspektiv ser det
6583 ut som en svært behagelig sak. For brukerne er det vel både en fordel
6584 og en ulempe at det ikke er Windows. Men vi håper at fordelene med et
6585 fritt system etterhvert vil bli åpenbare for både elever, lærekrefter
6586 og foreldre.
</p
>
6588 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6590 <p
>Vel, ulempen er vel først og fremst at andre aktører med mer
6591 kapitalmuskel har klart å etablere seg som det både lærere og foreldre
6592 føler seg trygge på, selv om det etter mitt hode ikke er noen grunn
6593 til å være spesielt trygg på de kommersielle alternativene.
</p
>
6595 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
6597 <p
>Når jeg får bestemme helt selv, bruker jeg kun fri programvare. Da
6598 helst med vekt på ting som kjører greit på OpenBSD. Hjemme er det
6599 OpenBSD, Ubuntu eller FreeBSD vi bruker. På skrivebordet er det en
6600 avveining mellom Gnome, KDE eller hva-det-nå-heter som er
6601 standardvalget i Ubuntu, ellers er det de kjente tingene som
6602 LibreOffice, Emacs, mplayer. På server er det selvfølgelig Apache,
6603 for overvåking både OpenNMS og Nagios (det bare ble sånn, og
6604 forskjellige siter). Jeg skriver til tider om slikt jeg holder på med
6606 <a href=
"http://bsdly.blogspot.com
">http://bsdly.blogspot.com
</a
>.
</p
>
6608 <p
>Men vi må nevne at selv vi har en Microsoft-ting som vi slår på når
6609 vi av en eller annen grunn må. Det betyr igjen vanligvis når en
6610 mobiltelefon eller en annen lukket elektronisk dings krever kontakt
6611 via en slik for å få oppdateringene sine.
</p
>
6613 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
6614 skoler til å ta i bruk fri programvare?
</strong
></p
>
6616 <p
>Hadde vi hatt det rette svaret på det spørsmålet, så hadde vi
6617 gjerne hatt Skolelinux som førstevalg på alle skoler ;)
</p
>
6619 <p
>Men jeg tror vi må legge vekt på flere forskjellige ting. En helt
6620 sentral sak er å fokusere på fri programvare og åpne standarder som de
6621 demokratiske verdiene de faktisk er. Det har kanskje kommet litt for
6622 mye i bakgrunnen i forhold til strevet etter å lage det mest mulig
6623 'brukervennlige
' systemet. Det er en tung vei å gå, så det er
6624 forståelig at freenix-aktivister heller velger å skrive kode og annet
6625 som er mer lystbetont. Mer praktisk tror jeg vi må gjøre i alle fall
6626 to ting: For det første sørge for å fortsette med å levere det best
6627 mulige frie produktet, slik at det er lett å både komme i gang og
6628 holde systemene i daglig drift, og for det andre
2) spore opp mulige
6629 aktivister der de finnes, via lokale brukergrupper, sosiale medier
6630 eller annet og sørge for at de fortsetter å være aktive. Mer og
6631 mindre uformelle treff kan være nyttig i tillegg til de mer
6632 organiserte møtene med foredrag, konferanser og utviklersamlinger.

6649 <p
>Mitt navn er Frode Jemtland, og jeg jobber i Hedmark IKT, som er et
6650 driftsselskap for Grue, Hamar, Kongsvinger, Løten, Nord-Odal og Stange
6651 kommuner. Her er jeg leder for avdelingen Løsninger og Arkitektur. Vi

6655 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
6657 <p
>Jobbet i IBM fra
2000, og da spesielt med Linux. Dette var da et av
6658 de mest tydelige linux prosjektene i Norge, og her ønsket jeg å
6659 bidra. Var aktivt med i prosjektet i
4-
5 år.
</p
>
6661 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6663 <p
>Fordelene slik jeg ser det er den sentraliserte driftmodellen, og
6664 alle de vel gjennomtenkte løsningene som er inkludert i denne
6665 løsningen. Samtidig er det basert på en stabil, og godt kjent
6666 plattform. Dette vil si at man har en løsning som skal være mye
6667 tilgjengelig, og hvor det er relativt enkelt å få tak i personer som
6668 kan mye om den grunnleggende plattformen.
</p
>
6670 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6672 <p
>De største utfordringene med en løsningen er at den er intensiv på f.eks
6673 nettverk. I seg selv ikke et problem for en enkelt skole, men skal løsningen
6674 kjøres i større skala, med sentraliserte servere, så gir dette noen
6675 utfordringer.
</p
>
6677 <p
>Utifra hva jeg har sett på større installasjoner så er det ikke så
6678 enkelt å skjønne, hva som bør gjøres for at den skal skaleres opp, og
6679 da ta godt vare på alle sider av dette, ikke bare mer server å fordele
6680 last/trykk, men hvordan også beholde robustheten og fleksibiliteten i
6681 løsningen.
</p
>
6683 <p
>En annen utfordring er at stadig flere produkter som skal brukes i
6684 skoleløsningen ikke er laget til å kunne brukes i en
6685 skolelinuxløsning. Det blir derfor fort mye skreddersøm i de
6686 forskjellige installasjonene, for å få diverse pedagogiske programmer,
6687 webløsninger, smartboards, m.m. til å fungere. Man er også en for
6688 liten kundebase til at leverandørene ønsker å gjøre noe med
6689 utfordringen. Problemet overlates til oss.
</p
>
6691 <p
>Det er også en kontinuerlig utfordring rundt problemet med å holde
6692 programvare på stabile versjoner, kontra å få ny funksjonalitet. Dette
6693 er jo en konflikt mellom oss som ønsker å drifte en stabil, og
6694 kostnadseffektiv løsning, mot sluttbrukerne som ønsker seg funksjoner
6695 det er vant med fra andre løsninger, eller som de må ha for at et
6696 eller annet nytt produkt skal fungere i løsningen. Dette er en
6697 utfordring også for andre plattformer.
</p
>
6699 <p
>En siste utfordring som ikke har noe med løsningen å gjøre, men med
6700 det omkringliggende miljøet denne skal kjøre i, er at de enhetene som
6701 skal drifte dataløsninger for kommuner og fylkeskommuner begynner å
6702 profesjonaliseres, og er da avhengig av å ha standard løsninger for å
6703 drifte store brukermasser. MS er selvsagt klar over dette, og har jo
6704 nå flere områder de begynner å bli veldig dominerende på. Den største,
6705 og mest problematiske er katalogtjenesten. Man får snart ikke tak i
6706 større løsninger som ikke krever en AD. Når man da har store enheter
6707 som drifter både kommunalt ansatte og skoler, så vil det være et
6708 stordriftargument å standardisere på en katalog tjeneste, og da har
6709 man ikke noe valg. Her er alle slike driftsenheter for små til å få
6710 gjort om på dette. Her burde konkurransemyndighetene kommet på
6711 banen. Men konkurransetilsynet i USA griper sjeldent (og ikke før det
6712 har gått veldig lang tid) inn i monopolsituasjoner så lenge
6713 monopolisten er et amerikansk firma, så da har vel ikke andre
6714 myndigheter så mye de skulle ha sagt....

6716 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
6718 <p
>Privat kjører jeg Debian på alle mine datamaskiner. Det gjør jeg
6719 også på min jobbmaskin. Vi har også
15-
20 linux servere av typene
6720 SuSE, Debian, Redhat, CentOS m.m. Jeg bruker derfor mye fri
6721 programvare. Av enkelt programmer kan sikkert masse nevnes. Hvis vi
6722 skal begrense oss til daglig, så må jeg si: OpenOffice, Firefox,
6723 Kontact, Kopete, Amarok,
6724 <a href=
"http://gramps-project.org/
">Gramps
</a
>, Kate, ssh, bash,
6725 rsync, backuppc m.m.
</p
>
6727 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
6728 skoler til å ta i bruk fri programvare?
</strong
></p
>
6730 <p
>Det er et godt spørsmål, som jeg har lurt på selv.
</p
>
6732 <p
>Argumentene som ofte har vært brukt om at ting koster mindre holder
6733 ikke mål når man ser på hva som faktisk koster penger. Det er de
6734 ansatte som er en kostnadsdriver. Det vil si at hvis man har et system
6735 som den ansatte kan, så vil en kostnad på dette systemet kunne
6736 forsvares ganske mye ved at den ansatte gjør dette raskere og
6737 effektivt. Også uten å måtte eventuelt leie inn folk.
</p
>
6739 <p
>Jeg syns det er viktigere å fokusere på prinsippet med å velge fri
6740 programvare, men det er også et felt hvor man fort møter lite
6741 forståelse blant de ansatte i skolen.
</p
>
6743 <p
>Her må nok strategien fortsette å være at de sentrale myndighetene
6744 må sende tydelige signaler for hva de ønsker at offentlige enheter
6745 skal gjøre. Det var mye positivt på gang ang. dette for et par år
6746 siden. Både med eNorge og eKommune planene, men dette syns jeg har
6747 stoppet opp. En del av dette kan jo kanskje være usikkerheten som
6748 etter hvert har blitt, når man har sett kompleksiteten i de
6749 prosjektene som har blitt igangsatt. Det har også blitt noe usikkerhet
6750 i markedet ref. Sun, Oracle, Novell, Microsoft m.m. Samtidig har jo
6751 også de proprietære programleverandørene sørget for å endre sine
6752 lisenser slik at man uansett ikke slipper unna kostnaden til deres
6753 produkter, selv om man skulle velge alternativer. Da er det økonomiske
6754 argumentet, som jeg nevnte tidligere, spilt ganske godt ut over
6755 sidelinjen.

6779 hadde vel hørt om prosjektet i media før en gjeng i Trondheim startet
6780 opp SPIST, Skolelinux-prosjektet i Sør-Trøndelag, hvor vi hjalp noen
6781 skoler i nærområdet med å installere Skolelinux og finne brukt
6782 IT-utstyr til disse. Det var moro å gjøre noe praktisk for å spre
6783 Skolelinux, og å se hvor fort gjort det var å sette opp utrangerte
6784 klientmaskiner og få disse opp som tynnklienter på helt nye datasaler
6785 på skolene, kun med kostnaden til servere.

6816 fleksibilitet, åpenhet og ikke låsing til en leverandør framfor sparte
6817 lisenskostnader, samt programvarens kvalitet og fortrinn, og at den
6818 fritt kan brukes på et ubegrenset antall PC-er, også hjemme hos
6819 elevene. En bør også forbedre den fri programvaren ved testing,
6820 bugrapportering og kodebidrag om man kan, og ikke anbefale programvare
6821 uten at man har forsikret seg at den har tilstrekkelig kvalitet,
6822 ellers kan man lett oppnå det motsatte. Tror en bør selge inn
6823 konseptet til fylkes-/statsnivå, kanskje med bidrag til
6824 utviklingsarbeid fra disse som alle landets skoler kan få glede

>Mine bloggposter om Linux i skolene i Norge førte til at inspektør
6835 og ildsjel på Harestad skole tok kontakt og fortalte at de bruker
6836 Linux på sin skole, og lurte på om de kunne bidra til å gjøre
6837 fordelene kjent. Riktig nok bruker de ikke

2002 begynte daværende IKT-ansvarlige og jeg et arbeid på skolen
6851 med å gå over fra Win98 til... noe annet. Vi testet en rekke
6852 forskjellige løsninger, deriblant Skolelinux, men endte opp med
6853 RedHat. Skolelinux var den gang ikke modent for det vi ville ha. Jeg
6854 har siden fulgt jevnlig med på hva skolelinux holder på med, men har
6855 hele tiden vært bedre fornøyd med vår egen
"standardiserte

6876 mot windows (de kjøper en
<strong
>masse
</strong
> konsulenttjenester
6877 fra ErgoGroup).
</p
>
6879 <p
>I kvantitet er Harestad og Grødem skole tilsammen et større
6880 IT-system enn resten av Randaberg kommune + Kvitsøy og Rennesøy, som
6881 kommunen også har driftsansvar for. Vi har som sagt rundt
800
6882 maskiner, mens kommunen med sitt driftsansvar har ansvar for rundt
500
6883 maskiner. Det er selvfølgelig litt forskjell i hvor kritiske
6884 tjenestene våre er, men det gir allikevel et litt rart bilde når
6885 IT-avdelingen overhode ikke er interessert i å snakke med oss om
6886 hvordan vi gjør ting :-)

6890 <p
>Fra linux-perspektivet (ikke bare Skolelinux) er det en fordel av
6891 systemet er basert på fri programvare - og dermed fritt i ordets mange
6892 betydninger. Det er alt vi trenger: stabilt, relativt enkelt å drifte
6893 (tross alt - et større windowssystem er ikke enkelt å holde live det
6894 heller), rimelig i innkjøp og drift, og sist, men ikke minst, det er
6895 moderne for sluttbruker! Linux, i sine mange varianter,
6896 <strong
>ser
</strong
> nytt ut, fordi det hele tiden blir
6897 oppdatert. Derfor lever systemet opp til hvordan elever forventer at
6898 et moderne GUI skal være (i motsetning til WinXP :-).
</p
>
6900 <p
>Vi var veldig pragmatiske da vi begynte med linux i skolen. Det var
6901 billig, det fungerte og kunne bruke alle de gamle windows-maskinene
6902 som
"nye
" tynne klienter. I dag er vi mer bevisste fri
6903 programvare-tilhengere. Vi har oppdaget hva det er - og vi liker
6906 <p
>En av de
<strong
>store
</strong
> fordelene med fri programvare er at
6907 vi kan installere tjenester vi ønsker å tilby brukerne våre - uten å
6908 måtte tenke på om vi har råd til lisensene (fordi det er ingen). Alt
6909 vi setter i produksjon er ut i fra brukernes behov og vår kapasitet
6910 til å drifte dem. Vi skreddersyr tjenestene etter behovet og dermed
6911 trenger vi ikke ende opp med å kjøpe en pakke der vi egentlig bare var
6912 interessert i en liten del av den.
</p
>
6914 <p
>Bruk av linux frigjør ikke økonomiske midler, fordi midlene til IKT
6915 i skole er for få i utgangspunktet - men vi får så
6916 <strong
>mye
</strong
> mer igjen for dem når vi bruker en linux-løsning
6917 fremfor en windows-løsning. I praksis ser vi at vi måtte ut med det
6918 dobbelte på budsjettet vårt om vi skulle hatt en tilsvarende
6919 windows-løsning, som det vi i dag drifter med linux.
</p

6921 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6923 <p
>Ikke all pedagogisk programvare er tilgjengelig. Det er en del
6924 programvare i skolen som er laget med utviklerverktøy som bare virker
6925 i windows, f.eks. Drillpro, LingDys/LingWrite. Det er også
6926 "programmer
" som bare virker om du har tilgang til Microsoft Office,
6927 f.eks. AskiRaski.
</p
>
6929 <p
>Vi sliter også litt med at video-codecer ikke alltid er like lett å
6930 få opp å gå på klientene. Det er alltid en eller annen videosnutt fra
6931 nrk.no som ikke er så samarbeidsvillig, uansett mediaplayer.
</p
>
6933 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
6935 <p
>Alt :-) På skolen bruker vi det som finnes og som er nyttig. Det vi
6936 bruker mest er Firefox (jobber med Chrome, fordi det er
6937 <strong
>mye
</strong
> raskere med Flash enn Firefox), OpenOffice (skal
6938 over til LibreOffice), GIMP osv. Standardpakken av
6939 sluttbrukerprogrammer.
</p
>
6941 <p
>På tjenernivå bruker vi OpenWebMail (skal over til Zimbra), Exim
6944 <p
>Personlig bruker jeg de fleste programmer over flere plattformer,
6945 men jeg har lagt meg til en vane å prioritere bruken av fri
6946 programvare også i Windows
7 og OSX.
</p
>
6948 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
6949 skoler til å ta i bruk fri programvare?
</strong
></p
>
6951 <p
>Jeg er langt i fra sikker. For det første handler det mye om at
6952 IKT-avdelingen i kommunen ofte er de som styrer hva som er IKT på
6953 skolene - og de liker å bruke avtalene med Microsoft, som de garantert
6954 har fra før. Dessuten - Select
6-avtalen til skolene gjør Microsoft
6955 skvettbillig.
</p
>
6957 <p
>Vi la vekt på effektiv drift av systemet - og at vi kunne øke
6958 antall maskiner uten å måtte øke budsjett for utstyr eller personell
6959 særlig mye, enn om vi hadde gått for en Microsoft-løsning. I praksis
6960 ser vi at en ren linux-installasjon driftes til halve prisen av en
6961 Microsoft-løsning.
</p
>
6963 <p
>Vi har i praksis også sett at det lærerne (og elevene) liker er at
6964 vi tilbyr
<strong
>veldig
</strong
> mange tjenester som ikke er så
6965 vanlige i en Microsoft-løsning. Det er ikke så vanlig at
6966 <strong
>elevene
</strong
> også har epost, hjemmekontor osv. Det har vi
6967 også brukt som et vellykket argument mot Microsoft.
</p
>
6969 <p
>Den beste måten er selvfølgelig at noen bare bestemmer
6970 det. Problemet er å få dem som har makt til å bestemme det til faktisk
6971 å gjøre det ;-)

6987 <p
>Jeg heter Astri Sletteng. Jeg er lærer og IKT veileder ved Håkvik
6988 skole i Narvik kommune. Min bakgrunn når det gjelder IKT: Av formell
6989 utdannelse har jeg lærerutdanning, Master i skoleledelse og IKT for
6990 lærere. Har jobba som IKT veileder siden
2002.
</p
>
6992 <p
>Det viktigste for meg som IKT veileder er å få fundamentert den
6993 5. basisferdigheten, digital kompetanse ved skolen min på en god måte
6994 slik at hele skolesamfunnet tar i bruk IKT i alle fag. Dette arbeidet
6995 gjøres i nært samarbeid med skolens ledelse.
</p
>
6997 <p
>Min viktigste jobb som IKT veileder er å være motivator og pådriver
6998 i IKT arbeidet ved skolen.
</p

7000 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
7002 <p
>Jobber i en kommune hvor vi satser på Fri programvare. I
2004 ble
7003 det gjort et politisk vedtak om at vi skulle innføre Skolelinux ved
7004 alle skolene i kommunen. Jeg har dermed en god del erfaring med
7005 Skolelinux, samt annen fri programvare som Open Office, Joomla, Moodle
7008 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7010 <p
>Siden vi jobber med åpen kildekode kan vi få programmene og
7011 produktene tilpasset vår bruk. Det er jo heller ikke en ulempe at
7012 skolen kommer bedre ut økonomisk, men først og fremst er det viktig
7013 for oss at vi har digitale systemer som gjør at vi kan følge
7014 læreplanen i alle fag. Det syns jeg at vi kan gjøre gjennom
7015 Skolelinux.
</p
>
7017 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7019 <p
>Skolen er avhengige av å ha folk på IT avdelinga i kommunen som kan
7020 drive support, og være tilgjengelige når vi trenger hjelp. Det er en
7021 ulempe at ikke alle på denne avdelingen nødvendigvis er god på
7024 <p
>Vi har også noen utfordringer når det kommer til spesielle
7025 programmer som enkelte elever er avhengige av ? og som ikke er
7026 plattform uavhengige. Her har vi i Friprog-verden, men også
7027 departement en jobb å gjøre.
</p

7029 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong

7031 <p
>Skolen vår bruker Skolelinux, Open Office, Iceweazel (Mozilla),
7032 VLC, Tux paint, Scribus, FreeMind, GIMP, digiKam, Ksnapshot, GeoGebra,
7033 Moodle (innført på alle klassetrinn + som et administrativt verktøy)
7034 og Joomla som hjemmeside.
<p
>
7036 <p
>Det er de jeg kommer på i farten. I tillegg har vi Smartboard
7037 installert på server, men det regnes vel ikke som fri programvare?

7039 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
7040 skoler til å ta i bruk fri programvare?
</strong
></p
>
7042 <p
>Først og fremst trenger skolen oppetider på sine datasystemer. Syns
7043 også at det at vi kan få tilpasset plattform og systemer til vår bruk
7044 er en god strategi å bruke.

>Rubén Romero y Cordero,
81-modell, deltidspappa (
50%) for en jente
7061 på
6 år. Jobber i Oslo som Global Sales Executive hos Varnish Software
7062 og til daglig har jeg kontakt med kunder fra hele verden. Min
7063 forkjærlighet for fri programvare har gjort at jeg har nå flere års
7064 erfaring med salg av slike løsninger (bl.a. fra Redpill Linpro og
7065 Freecode) og mye innsikt og kunnskap om det globale IT-markedet.
7066 Ellers er jeg involvert i flere prosjekter bl.a. er jeg Ubuntu
7067 Community medlem, kontaktpersonen for Ubuntu Norge og driveren av
7068 SpreadUbuntu marketing prosjektet og nå fersk styremedlem i FRISK. Jeg
7069 har brukt GNU/Linux siden
1997.

</strong

7073 <p
>Som Debian bruker siden slutten av
90-tallet var det uunngåelig å
7074 ikke komme bort i Skolelinux. Dette var vel i slutten av
2001 når jeg
7075 var student ved UiO. Flere år senere fikk jeg lastet og testet Venus
7076 (Skolelinux
1.0) på release dagen.

7078 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7080 <p
>Fri programvare bygges sten for sten i det åpne, slik at koden og
7081 prosessen den lages på kan gjennomskues av andre enn de som har laget
7082 det. Det er et vitenskapelig og gjennomsiktig måte å lage programvare
7085 <p
>Skoler i vårt samfunn skal være steder hvor vitenskapelig kunnskap
7086 deles til alle. I dag har vi ikke et vitenskapelig tilnærming til
7087 hvordan programvaren som brukes på skolen lages. Skolelinux bringer
7088 inn at slik tilnærming i skoleverkets klasserom, siden
7089 operativsystemet er en åpent platform som gir skolene muligheten til å
7090 dra nytte av programvare som er laget av tusenvis av mennesker verden
7091 rundt og som gir elevene så vel som lærerne muligheten til å bruke,
7092 dele, forandre og forbedre OSet sitt uten begrensninger. I den
7093 forbindelsen representerer Skolelinux også konkrete resultater utfra
7094 samhandling på tvers av grenser.
</p
>
7096 <p
>Når det gjelder de tekniske fordelene av Skolelinux er jeg sikker
7097 på at andre enn meg har allerede beskrevet disse bedre enn det jeg
7098 kan. Men jeg kan likevel tilføye noe: Skolelinux som sådan er en
7099 community-drevet operativsystemplatform. Som i ethvert
7100 community-prosjekt har alle Skolelinux brukere muligheten til å
7101 påvirke retning av prosjektet og resultatet som gjenspeiles i
7102 programvaren. Dette kommer sjeldent frem og jeg mener at det er noe
7103 som burde fokuseres mer på.
</p
>
7105 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong

7107 <p
>De største ulempene er:
</p
>
7110 <li
>Mangel på kompetanse
</li
>
7111 <li
>Mangel av administrative verktøy som kunne hjelpe lokale IT
7112 avdelinger å bruke Skolelinux til mer enn bare en tjener for
7113 terminalklienter. Et eksempel: Zentyal sin web-dashboard.
</li
>
7116 <p
>Bedre og mer intuitive administrative verktøy kunne løst deler av
7117 problemet, men det er unektelig at ved bruk av Skolelinux må
7118 IT-personalet vite hva de gjør for å få ting gjort riktig, eller i det
7119 hele tatt. Med andre platformer er kompetansen enklere tilgjengelig og
7120 løsningene kan fungere på en tilfredstillende, om ikke riktig

7125 <p
>Har brukt GNU/Linux utelukkende sommitt skrivebord OS siden
2000. I
7126 dag bruker jeg Ubuntu og gjør det meste med friprogramvare verktøyene
7127 som er tilgjengelige der. Med over
20.000 programmer å velge mellom er
7128 dette mer enn nok for de fleste brukerne.

7134 programvare. De fleste utfordringene skolene har på IKT-siden kan
7135 løses ved hjelp av friprogramvareverktøy i dag. Det som trenges er
7136 opplysning, kunnskap og kompetanse.

7163 <p

7164 entusiastiske skolelinuxbrukere og skeptiske
"forståsegpåere

7166 <p
>Jeg husker en leverandør av et stort OS for noen år siden mente at
7167 Skolelinux var kun for hackere og nerder og at ingen seriøse skoler
7168 kunne ta dette i bruk. Heldigvis er kunnskapen større nå og
7169 skikkelige
"IT-folk

7171 <p

</strong

7173 <p
>Ja det er mange fordeler. Uavhengighet, stabilitet, åpenhet, standarder

7177 <p

7179 <p
>Det største hinderet er det vi opplever på andre områder rundt
7180 fri programvare, nemlig kunnskap. For mange er det trygt å velge det vi
7181 alltid har valgt. Fordi leverandørene rundt oss sitter på den kunnskapen og
7182 de vi støtter oss på har den samme. Hvis vi klarer å riste løs litt og
7183 glemme gamle kriger mellom operativsystemer og leverandører, men sette ned
7184 hva som er viktig og velge ut fra det, så hadde man kanskje kommet ut med
7185 litt andre resultat. Jeg tror IT-folk er konservative og velger tradisjonelt
7186 og det er synd.

7190 <p
>Jeg bruker Ubuntu, Android, Jolicloud, Open Office, Zimbra, Picasa

7192 som er betalingslisens for er OSX. Ser at jeg jobber mer og mer i
7193 skyen og setter pris på alt jeg slipper egen klient til. Derfor er
7194 jeg veldig sjarmert av små kjappe operativsystemer som krever minimalt
7195 av maskinvaren.

7200 <p
>Tror en blanding av krav og informasjon er veien å gå. Krav om
7201 sikkerhet, oppetid og åpne standarder. Informasjon om muligheter og
7202 alternativer. Her har leverandører, IT-avdelinger og pedagoger en vei
7203 å gå sammen. Det er til slutt LÆRING det dreier seg om, og da må man
7204 få mest mulig læring for pengene man har.

7222 vidareutviklar og er andrelinje brukarstøtte for datanettet ved
7223 skulane i Flora kommune.
10 skular og meir enn
700 maskiner med
7224 Linux, medrekna tynnklientar. Tidlegare jobba eg i mange år med
7225 unix-drift ved Universitetets senter for informasjonsteknologi ved

7230 <p
>Det er vanskeleg å svare konkret på. Eg har drive med Unix og Linux i
7231 alle år, og Skulelinux er eit godt kjent prosjekt i miljøet. Det var
7232 først i
2008, då eg tok til i min noverande jobb, at eg fekk bruk for
7233 Skulelinux for alvor.
</p
>
7235 <p
>Jobben min skulle vere drift av eit nytt skulenett i Flora kommune,
7236 levert av eit firma eg ikkje vil reklamere for. Systemet skulle vere
7237 ferdig levert i september året før. Dette viste seg å ta mykje lenger
7238 tid, og i haustferien
2008 hadde dei endå ikkje klart å få opp ei
7239 fungerande løysing. Situasjonen var prekær for den største skulen i
7240 kommunen med meir enn
500 elevar på ungdomssteget. Skulen hadde brukt
7241 Skulelinux før, og var tilfredse med det. No hadde dei vore utan
7242 fungerande datasystem i nesten eit år. Difor fekk eg opp ein ny tenar
7243 utanfor prosjektet og installerte Skulelinux på den. Etter litt
7244 justering av konfigurasjonen med god hjelp av #skolelinux på IRC, var
7245 den nye tenaren oppe og gjekk med både tynne og halv-tjukke klientar.
7246 Autentisering gjekk mot det nye systemet, slik at elevar og lærarar
7247 framleis har same brukarnamn og passord over alt. Dette berre
7248 fungerte, og vi bestemte oss for å erstatte delar av løysinga vi
7249 skulle få levert med Skulelinux.
</p
>
7251 <p
>Det høyrer med til historia at det nye systemet eg skulle drive frå
7252 januar
2008 endå ikkje er ferdig levert. Dei jobbar med saka, seier
7253 dei, og har von om å fullføre leveransen i løpet av
2011.

>Den viktigaste fordelen er at det igrunn berre er ei maskin å passe
7260 på, og det er tenaren. Med andre løysingar har ein gjerne programvare
7261 og anna som skal vedlikehaldast på kvar enkelt maskin. Med Skulelinux
7262 kan alle feil rettast og alle program oppgraderast på alle maskiner
7263 samstundes ved å gjere endringa som må til på tenaren. Eg kan sitje
7264 på kontoret og passe på alle tenarane i kommunen derifrå.

7268 <li
>Tynne klientar gjer det mogleg å bruke eldre utstyr lenge, so lenge
7269 tenaren er sterk nok. Ein liten tenar med eit par halv-moderne CPUar
7270 og
2 GiB RAM held lenge for eit typisk klasserom med
30 tynnklientar,
7271 og det er lett å utvide med fleire.
7273 <li
>Halvtjukke klientar gjer det mogleg å utnytte kapasiteten i litt
7274 nyare maskiner betre, og avlaste tenaren. Ingenting vert installert
7275 lokalt på desse heller, og harddisken kan gjerne koblast frå. Gode
7276 halvtjukke klientar kan kjøpast brukt for under
1000-lappen, og det er
7277 heile kostnaden. Ingen lisensar eller anna på toppen, og det er ikkje
7278 krav til kraftigare tenar heller.
7280 <li
>Det er Linux. Vi har ikkje noko kluss med drivarar, dei berre er
7281 der. Heller ikkje med virus, dei finst i realiteten ikkje. Eller med
7282 elevar som klussar med installert programvare, for dei klarar ikkje å
7283 øydeleggje for nokon andre enn seg sjølve.
7287 <p
>Skulelinux er lagt opp til å vere veldig lett å installere rett ut
7288 av boksen på ein heil skule av ein interessert lærar. Det er ofte ei
7289 god løysing for skulen. Å ha nokon til stades som kjenner systemet og
7290 kan forklare enkle ting eller løyse problem der og då, er uvurderleg
7291 viktig for ein stressa lærar fem minutt før det ringer inn.

7295 <p
>All den ferdige konfigurasjonen gjer det tungvint å tilpasse
7296 Skulelinux til eit system som skal fungere saman med mange andre
7297 installasjonar i eit felles datanett for skulane i ein kommune. Det
7298 heile er prekonfigurert for ein skule, og utviding til mange skular
7299 med eigne tenarar er ikkje berre enkelt.

7304 samt scriptspråket perl. Elles er Firefox/Iceweasel, Gnome-terminal
7305 og ssh i kontinuerleg bruk. Av Linux-distribusjonar brukar eg både
7306 Debian, Ubuntu, SuSE og RedHat dagleg. Eg prøvar å finne det verktyet

7312 <p

7313 manglar eller har eit lite tilfredsstillande opplegg i dag, og ikkje
7314 har råd til å kjøpe noko nytt og blankpussa opplegg. Der er det om å
7315 gjere å gjere det enkelt for skulane å finne Skulelinux, og gjere det
7316 enkelt for dei å få hjelp til installasjon på skulen. Gjerne med
7317 lokale kontaktpersonar. Her er det dugnadsinnsats som må til, for
7318 desse skulane har ikkje råd til å betale for dette.
</p
>
7320 <p
>Den andre og kanskje viktigare målgruppa er dei meir eller mindre
7321 profesjonelle kundane. Alle store offentlege innkjøp, inkludert
7322 innkjøp av nytt datasystem for skular, må ut på offentleg anbod.
7323 Offentlege anbod er mykje meir lukka enn dei gjev inntrykk av, og både
7324 regelboka og boka med triks for å sminke tilbodet er tjukk. Det er
7325 vanskeleg å komme inn utan eit solid salsapparat i ryggen. Kanskje
7326 Skulelinux skulle prøve aktivt å få seg eit partnarskap med eit av dei
7327 store som gjerne vil sterkare inn på den offentlege IT-marknaden?
7328 Nokon som kjenner triksa og har krefter til å ta opp kampen mot både
7329 dårlege anbod og Rudolf Blostrupmoen IT AS. Leveranse til skulane i
7330 ein kommune er ein god måte å få ein fot inn døra som leverandør til
7331 ein lukrativ kommunemarknad som kjøper alle tenester. Ta kontakt med
7332 nokon som er passeleg store og ikkje er Microsoft-partnar, og fortell:
7333 «Vi har eit ferdig produkt som du kan selje. Nei vi skal ikkje ha for
7334 det. Du kan gjerne gjere kva du vil med det, berre vi får lov til å
7335 hjelpe deg. Målgruppa er alle kommunar, og det er noko dei vil ha.
7336 Det er eit godt produkt, brukt av mange og godt likt.»

>Embrik Kaslegard,
1964-modell, fire barn (
7-
20 år). Begynte som
7353 lærer i
1989 - har hatt IKT-ansvar siden første året i jobb. Har
7354 jobbet som lærer/IKT-ansvarlig uavbrutt siden
1989. Jobbet med

2004 til
2010. Nå har jeg fått ny arbeidsplass og er
7356 40% lærer og
60% IKT med Windows XP, Win2003 server og et regionalt
7357 IKT-regime som legger premissene og begrensingene for hva vi kan gjøre
7358 på skolen.

7362 <p
>Jeg leste en artikkel om en dugnadsinstallasjon av Skolelinux på en
7363 skole på Jæren et sted. Tanken om dugnad og frihet appellerte til
7364 meg. Da vi skulle bygge ny skole var det en del vi måtte spare på,
7365 fordi vi beveget oss mot en kostnadssprekk. Kabling og investering i
7366 PC-er var en av tingene vi sparte på. Derfor kjøpe vi
72 pc-er for
390
7367 pr stk. En filtjener og en applikasjonsserver.

7369 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7371 <p
>Fordelen er at så mye er satt opp fra starten. I tillegg er det
7372 tydelig at pakka er laga for skoleverket. Brukerne har egne
7373 skrivebord, tilgang på mange gode verktøyprogrammer. Vi slipper å
7374 tenke på virus. Brukerne har ikke mulighet til å ødelegge
7375 klientoppsett, men har gode muligheter til å endre eget oppsett. Dette
7376 tror jeg er inspirerende og kjekt for mange brukere. Mappestrukturen
7377 er ferdig og det er
"enkelt
" å designe lokale mappestrukturer via
7378 skeleton. Noen av oss i skoleverket mener skolen skal være en
7379 "mot-kultur
". Da er Skolelinux et av valgene man kan ta. Et annet er å
7380 spise på indisk restaurant i stedet for Mc Donald
's når vi er på bytur
7381 osv.. Ordene deling, frihet, dugnad osv er positive ord i
7382 skoleverket. Det er viktig at elevene blir bevisst dette.

7384 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7386 <p
>Kompabiliteten er selvsagt et problem, selv om det er mindre nå enn
7387 før. For IKT-personer på skolene som skal drifte dette er det
7388 problematisk med kommandoer i terminalen. I tillegg er det alt for
7389 mange programmer i Skolelinux som ikke blir brukt. Jeg tror
7390 Skolelinux er tjent med å tone ned begrepet pedagogisk programvare.
7391 Slik jeg ser det finnes ikke denne kategorien programmer lengre slik
7392 de gjorde før, som frittsående programmer som installeres på en
7393 datamaskin eller på serveren. Det finnes en del spesialpedagogiske
7394 programmer, som Textpilot, LingDys, LingRight, AskiRaski, Ny i Norge
7395 osv. Men dette er programmer for enkelt-elever eller små grupper av
7396 elever. Det som bør være fokus er at alle undervisningsressurser som
7397 lages for nettet skal være nettleseruavhengig.

7399 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
7401 <p
>OpenOffice bruker jeg til vanlig kontorarbeide. VLC bruker jeg som
7402 videoavspiller og av og til streaming av film. Gimp bruker jeg i
7403 undervisningen til bildemanipulering. Firefox og Chrome er mine
7404 favoritt-nettlesere. Firefox har lenge vært førstevalget mitt, nå
7405 bruker jeg mest Chrome. Opplever den som raskere og smidigere enn
7406 Firefox. Ubuntu bruker jeg som dualboot på jobb-maskinen min i
7407 tillegg til at alle PCer hjemme har en eller annen Ubuntu-distribusjon
7408 installert. Jeg bruker Clonezilla på Ubuntu
10.04 til kloning av
7409 datamaskiner på jobb. Det er selvsagt en haug andre frie programmer
7410 jeg bruker men jeg bruker dem ikke daglig. Jeg kan ramse opp:
7411 recordmydesktop, cinelerra, acidrip, soundjuicer, audacity, NX
7412 (no-machine), Kino, Rythmbox...

7414 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
7415 skoler til å ta i bruk fri programvare?
</strong
></p
>
7417 <p
>Jeg tror oppsøkende virksomhet er den rette strategien.
7418 Ressurspersoner gjør avtaler med rådmenn, skolesjefer, rektorer. Det
7419 er slik konkurrentene gjør det. Fokuset i slike samtaler bør være
7420 kost-nytte. Dersom personer med økonomisk ansvar ser at de kan få
7421 like godt tilbud til mindre utgifter, tror jeg det er mulighet til å
7422 få innpass. Dersom de også kan få konkrete tilbud på drift i slike
7423 samtaler, vil de kanskje bli litt mer interesserte i hvor mye penger
7424 som faktisk går til IKT i skolene. Det er også viktig at vi ikke
7425 firer for mye på krav til datamaskiner. Det er flott at Skolelinux
7426 går på
"utrangert
" utstyr, men dette bør bare presenteres som et
7427 alternativ. Skolelinux-installasjoner med utrangert utstyr er ikke å
7428 foretrekke dersom man kan unngå det. Det skaper ikke entusiasme hos
7429 brukerne (elever og lærere) når de bruker gamle datamaskiner som går
7430 tregt. Det er kjempefint med skoler som har kommet seg frem til
7431 Skolelinux og fri programvare av seg selv, men de lever på nåde.
7432 Slike valg må fundamenteres hos skoleeier.

7463 <p
>Gjennom en eller annen nettavis i
2001 der var det skrevet om
7464 Skolelinux. Artikkelen ga meg lyst til å prøve ut systemet.
</p
>
7466 <p
>Det startet i
2002 ved at jeg installerte en av de første utgavene
7467 av Skolelinux på en standard pc på Solneset skole i Tromsø. Denne var
7468 oppe fram til desember
2003 da jeg sluttet på den skolen og begynte i
7469 ny jobb i Narvik kommune.
</p

7471 <p
> I Narvik kommune var det i
2004 kun
2 servere på da totalt
15
7472 skoler. Disse var Windows NT baserte. På disse to skolene var det lite
7473 med maskiner. Jobben med å få Narvik Kommune opp på akseptabelt nivå
7474 virket å være formidabel. Men med hjelp av gode kollegaer og leder
7475 skrev jeg en IKT plan for Narvik kommune som ble vedtatt av politikere
7476 i august
2004. I denne planen ble det bestemt at Narvik kommune skulle
7477 bruke Skolelinux. Her ble det også satt av midler til kabling av god
7478 infrastruktur på alle skoler samt innkjøp av nye datamaskiner. Så i
7479 dag har vi
17 servere hvorav
13 er på Skolelinux, med ca
1500 klienter
7480 basert på tynne,
"halvtykke
" og et stort antall bærbare pcer basert på

7625 være en naturfaglærer som ble lei av å vente på kommunen. Det gjorde
7626 at vi bestemte oss for å ta ting i egne hender, og da vha

7628 raskt at dette var veldig lovende. Neste etappe var å gi alle lærere

2004), og så sette opp
16 PCer på to
7630 datarom. Vi har kun basert oss på å kjøpe inn brukte maskiner, og
7631 aldri dyrere enn
1000 kr pr klient. For to år siden så hadde vi
7632 klienter i alle klasserom, og totalt hadde vi da rundt
250 stk. Rundt
7633 40 klienter brukes av lærerne og kjører på en egen server. Elvene har
7634 resten, og kjører også en egen server. Servere har vi også kjøpt
7635 brukt,
2 år gamle servere koster
6-
7000 kroner.

7638 vaktmester har sammen med IKT-ansvarlig/Naturfaglærer lagt kabler til alle

7640 som er mulig å fjernstyre.

7653 selger/blåruss og skal fikse ALT. I vårt tilfelle betyr dette også
7654 sentralisering av drift. Den ny-ansatte på kommunens IT-avdelingen
7655 skal også ha jobb, og ser for seg å ta over skoledriften. Kommunen
7656 kjøper inn eksterne driftstjenester, og nekter i samme slengen å ta
7657 hensyn til skolen vår. Dette til tross for at vi alene har like mange
7658 datamaskiner som de andre til sammen.

7673 faktisk å åpne de porter OSV som vi måtte bruke.

7675 <li
>Vi blir pålagt å flytte på innsiden av det kommunale
7676 nettverket. Dette gjorde at vi mistet hjemmekontor for lærere og
7677 elever. Å få åpnet porter i kommunal brannmur var ikke
7678 aktuelt. Mulighet for fjerndrift ble også vekk i samme slengen.

7685 få bedre datatetthet, og komme opp på et nivå som ligner det vi
7686 har. De ser at vi kan avholde eksamen hvor alle
10. klassingene får
7687 sitte ved hver sin PC. Og de har fått tilbakemelding (klager) fra VGS
7688 om manglende datakompetanse på elevene som kommer fra dem. Dette fører
7689 videre til at kommunen endelig innser at de må ta grep.
</p

7691 <p
>Grepet betyr sentralisering, og farvel til vår plattform får vi
7692 høre. Det blir gjort en rekke bestemmelser og vedtak som vi ikke får
7693 være en del av. Det blir helt klart at vi må redusere antall maskiner,
7694 og det skal satses på bærbare maskiner. Siden vi ikke har fått tatt
7695 del i prosessene som angår oss, så bruker vi fagforening. Vi har ikke
7696 blitt hørt i forbindelse med endringer som er betydelig for vår
7697 hverdag, og greier å stoppe omlegging. I tillegg så har vi et politisk
7698 vedtak i kommunen på at vi skal kjøre Linux på elevnett, og dette

7700 tilsidesette.

7785 <p
>Jeg glemte å nevne at vi nå nesten ikke bruker tid på å drifte
7786 systemet vårt, noe som gjør at det aller meste av tid blir brukt til å
7787 støtte lærerne og elevene. F.eks så bruker vår IKT-ansvarlig den
7788 første timen på jobb,
0730-
0830 kun til å gå ute på arbeidsplassene
7789 til læreren. Dette for å kunne svare på små og store problem, gi tips
7790 og råd, eller bare for å plukke opp hva som er behovet ute i
7791 undervisningsarealene. Det er dessverre ikke slik at alle lærerne har
7792 nok digital kompetanse til å kunne formulere alle spørsmålene de har,
7793 men ved å kunne få vise eller lufte tanker med IKT-ansvarlig så er det
7794 utrolig hva som kommer fram.
</p

7798 <li
>Jeg ser at mange bruker økonomi som argument i forhold til å bruke
7799 SkoleLinux, og jeg skal ikke legge skjul på at det var dette som i
7800 utgangspunktet var årsaken til vårt valg. Men diskusjonene og kampen
7801 med kommunens IT-avdeling har gjort at vi har fått et noe annet
7802 fokus. Fordelene med drift og stabilitet, gjør at vi ville ha valgt
7803 samme løsning selv om den var dyrere. At vi slipper langt billigere
7804 unna, som følge av
0,- lisenskostnader og lave maskinvarekostnader, er
7805 bare en bonus.
</li
>
7807 <li
>Etter å ha kranglet oss til å få skikkelig oversikt over hva de
7808 andre skolene i kommunen bruker på IT, så har vi fått gehør for å få
7809 samme midler til innkjøp. Dette har gjort at vi nå kan kjøpe inn
7810 utstyr som de andre skolene bare kan se langt etter. Vi har nettopp
7811 kjøpt inn
3 videokamera i semiproff-klassen for å kunne lage film,
7812 samt sende live fra skoleteater/konserter. Vi har kjøpt inn digitale
7813 kompaktkamera til alle klassene. Vi har et team av lærere som skal i
7814 gang med å teste ut tablets på svake elever. Håpet et at teknologien
7815 kan være med på å gi noen av elevene litt mer motivasjon. Vi har kjøpt
7816 inn et halvt klassesett med pulsklokker, noe som har vist seg å være
7817 overraskende inspirerende for en del av elevene. Vi har også oss på
7818 fag på en høyskole litt lengre sør for oss, slik at
3 av oss nå skal
7819 ta faget
"Linux tjenestedrift
". Som inspektør og en del av skolens
7820 administrasjon er det veldig praktisk å kunne trå til hvis det
7821 kniper. Men IKT-ansvarlig har vært UTROLIG flink til å lage rene
7822 smørbrødlister for hvordan de mest vanlige driftsproblem løses, så det
7823 er lett for flere av oss å ta del i den daglige driften. Vi har svært
7824 stor nytte av lærling (som også hjelper to av naboskolene), men det er
7825 nesten blitt slik at det er om å gjøre å komme til først for å få løse
7826 problem. Det å få fingrene på problem og utfordringer er den aller
7827 beste læremester.

7841 bytte ut en av serverne våre, og da vil denne trolig bli satt opp som
7842 testserver for neste versjon av Skolelinux. På den måten vil vi i alle

7977 <description><p
>In the latest issue of Linux Journal, the readers choices were
7978 presented, and the winner among the multimedia player were VLC.
7979 Personally, I like VLC, and it is my player of choice when I first try
7980 to play a video file or stream. Only if VLC fail will I drag out
7981 gmplayer to see if it can do better. The reason is mostly the failure
7982 model and trust. When VLC fail, it normally pop up a error message
7983 reporting the problem. When mplayer fail, it normally segfault or
7984 just hangs. The latter failure mode drain my trust in the program.
<p
>
7986 <p
>But even if VLC is my player of choice, we have choosen to use
7987 mplayer in
<a href=
"http://www.skolelinux.org/
">Debian
7988 Edu/Skolelinux
</a
>. The reason is simple. We need a good browser
7989 plugin to play web videos seamlessly, and the VLC browser plugin is
7990 not very good. For example, it lack in-line control buttons, so there
7991 is no way for the user to pause the video. Also, when I
7992 <a href=
"http://wiki.debian.org/DebianEdu/BrowserMultimedia
">last
7993 tested the browser plugins
</a
> available in Debian, the VLC plugin
7994 failed on several video pages where mplayer based plugins worked. If
7995 the browser plugin for VLC was as good as the gecko-mediaplayer
7996 package (which uses mplayer), we would switch.
</P
>
7998 <p
>While VLC is a good player, its user interface is slightly
7999 annoying. The most annoying feature is its inconsistent use of
8000 keyboard shortcuts. When the player is in full screen mode, its
8001 shortcuts are different from when it is playing the video in a window.
8002 For example, space only work as pause when in full screen mode. I
8003 wish it had consisten shortcuts and that space also would work when in
8004 window mode. Another nice shortcut in gmplayer is [enter] to restart
8005 the current video. It is very nice when playing short videos from the
8006 web and want to restart it when new people arrive to have a look at
8007 what is going on.

8463 are virtual machines. And they have been Xen machines running on a
8464 fairly old IBM eserver xseries
345 machine, and we wanted to migrate
8465 them to KVM on a newer Dell PowerEdge
2950 host machine. This was a
8466 bit harder that it could have been, because we set up the Xen virtual
8467 machines to get the virtual partitions from LVM, which as far as I
8468 know is not supported by KVM. So to migrate, we had to convert
8469 several LVM logical volumes to partitions on a virtual disk file.

">a
8473 nice recipe
</a
> to do this, and wrote the following script to do the
8474 migration. It uses qemu-img from the qemu package to make the disk
8475 image, parted to partition it, losetup and kpartx to present the disk
8476 image partions as devices, and dd to copy the data. I NFS mounted the
8477 new servers storage area on the old server to do the migration.

8777 finally got around to do a test installation of Debian/Squeeze with
8778 kfreebsd. Installation went fairly smooth, thought I noticed some
8779 visual glitches in the cdebconf dialogs (black cursor left on the
8780 screen at random locations). Have not gotten very far with the
8781 testing. Noticed cfdisk did not work, but fdisk did so it was not a
8782 fatal problem. Have to spend some more time on it to see if it is
8783 useful as a file server for NUUG. Will try to find time to set up a

8795 supposed provide a school with all the services and user applications
8796 needed on the pupils computer network has always been hard. Even
8797 schools without Internet connections should be able to get Debian Edu
8798 working using this DVD.
</p
>
8800 <p
>The job became a lot harder when apt and aptitude started
8801 installing recommended packages by default. We want the same set of
8802 packages to be installed when using the DVD and the netinst CD, and
8803 that means all recommended packages need to be on the DVD. I created
8804 a patch for debian-cd in
<a href=
"http://bugs.debian.org/
601203">BTS
8805 report #
601203</a
> to do this, and since this change was applied to
8806 the Debian Edu DVD build, we have been seriously short on space.
</p
>
8808 <p
>A few days ago we decided to drop blender, wxmaxima and kicad from
8809 the default installation to save space on the DVD, believing that
8810 those needing these applications are few and can get them from the
8811 Debian archive.
</p
>
8813 <p
>Yesterday, I had a look what source packages to see which packages
8814 were using most space. A few large packages are well know;
8815 openoffice.org, openclipart and fluid-soundfont. But I also
8816 discovered that lilypond used
106 MiB and fglrx-driver used
53 MiB.
8817 The lilypond package is pulled in as a dependency for rosegarden, and
8818 when looking a bit closer I discovered that
99 MiB of the
106 MiB were
8819 the documentation package, which is recommended by the binary package.
8820 I decided to drop this documentation package from our DVD, as most of
8821 our users will use the GUI front-ends and do not need the lilypond
8822 documentation. Similarly, I dropped the non-free fglrx-driver package
8823 which might be installed by d-i when its hardware is detected, as the
8824 free X driver should work.
</p
>
8826 <p
>With this change, we finally got space for the LXDE and Gnome
8827 desktop packages as well as the language specific packages making the
8828 DVD more useful again.

8842 More signers and more funding is most welcome, and I am really curious
8843 how far we can get before the time limit of December
24 is reached.
8846 <p
>On the #gnash IRC channel on irc.freenode.net, I was just tipped
8847 about what appear to be a great code coverage tool capable of
8848 generating code coverage stats without any changes to the source code.

8852 It is missing in Debian, but the git source built just fine in Squeeze
8853 after I installed libelf-dev, libdwarf-dev, pkg-config and
8854 libglib2.0-dev. Failed to build in Lenny, but suspect that is
8855 solvable. I hope kcov make it into Debian soon.

8887 schools experienced with
<a href=
"http://www.skolelinux.org/
">Debian
8888 Edu/Skolelinux
</a
> was the lack of working Flash. A lot of educational
8889 web sites require Flash to work, and lacking working Flash support in
8890 the web browser and the problems with installing it was perceived as a
8891 good reason to stay with Windows.
</p
>
8893 <p
>I once saw a funny and sad comment in a web forum, where Linux was
8894 said to be the retarded cousin that did not really understand
8895 everything you told him but could work fairly well. This was a
8896 comment regarding the problems Linux have with proprietary formats and
8897 non-standard web pages, and is sad because it exposes a fairly common
8898 understanding of whose fault it is if web pages that only work in for
8899 example Internet Explorer
6 fail to work on Firefox, and funny because
8900 it explain very well how annoying it is for users when Linux
8901 distributions do not work with the documents they receive or the web
8902 pages they want to visit.
</p
>
8904 <p
>This is part of the reason why I believe it is important for Debian
8905 and Debian Edu to have a well working Flash implementation in the
8906 distribution, to get at least popular sites as Youtube and Google
8907 Video to working out of the box. For Squeeze, Debian have the chance
8908 to include the latest version of Gnash that will make this happen, as
8909 the new release
0.8.8 was published a few weeks ago and is resting in
8910 unstable. The new version work with more sites that version
0.8.7.
8911 The Gnash maintainers have asked for a freeze exception, but the
8912 release team have not had time to reply to it yet. I hope they agree
8913 with me that Flash is important for the Debian desktop users, and thus
8914 accept the new package into Squeeze.

>As reported earlier, the last few days I have looked at how Debian
9089 Edu clients are configured, and tried to get rid of all hardcoded
9090 configuration settings on the clients. I believe the work to be
9091 mostly done, and the clients seem to work just fine with dynamically
9092 generated configuration.
</p

9094 <p
>What is the point, you might ask? The point is to allow a Debian
9095 Edu desktop to integrate into an existing network infrastructure
9096 without any manual configuration.
</p
>
9098 <p
>This is what happens when installing a Debian Edu client here at
9099 the University of Oslo using PXE. With the PXE installation, I am
9100 asked for language (Norwegian Bokmål), locality (Norway) and keyboard
9101 layout (no-latin1), Debian Edu profile (Roaming Workstation), if I
9102 accept to reformat the hard drive (yes), if I want to submit info to
9103 popcon.debian.org (no) and root password (secret). After answering
9104 these questions, the installer goes ahead and does its thing, and
9105 after around
50 minutes it is done. I press enter to finish the
9106 installation, and the machine reboots into KDE. When the machine is
9107 ready and kdm asks for login information, I enter my university
9108 username and password, am told by kdm that a local home directory has
9109 been created and that I must log in again, and finally log in with the
9110 same username and password to the KDE
4.4 desktop. At no point during
9111 this process did it ask for university specific settings, and all the
9112 required configuration was dynamically detected using information
9113 fetched via DHCP and DNS. The roaming workstation is now ready for
9116 <p
>How was this done, you might wonder? First of all, here is the
9117 list of things that need to be configured on the client to get it
9118 working properly out of the box:
</p
>
9121 <li
>IP address/netmask and DNS server.
</li
>
9122 <li
>Web proxy URL.
</li
>
9123 <li
>LDAP server for NSS directory information (user, group, etc).
</li
>
9124 <li
>Kerberos server for PAM password checking.

>SMB mount point to access the network home directory. (*)
</li
>
9126 <li
>Central syslog server to send syslog messages to. (*)
</li
>
9127 <li
>Sitesummary collector URL to submit info to central server. (*)
</li
>
9130 <p
>(Hm, did I forget anything? Let me knew if I did.)

9135 but the sitesummary collector URL is dynamically discovered at boot
9136 and installation time in the svn version of Debian Edu.
</p
>
9138 <p
>The IP and DNS setup is fetched during boot using DHCP as usual.
9139 When a DHCP update arrives, the proxy setup is updated by looking for
9140 http://wpat/wpad.dat and using the content of this WPAD file to
9141 configure the http and ftp proxy in /etc/environment and
9142 /etc/apt/apt.conf. I decided to update the proxy setup using a DHCP
9143 hook to ensure that the client stops using the Debian Edu proxy when
9144 it is moved outside the Debian Edu network, and instead uses any local
9145 proxy present on the new network when it moves around.
</p
>
9147 <p
>The DNS names of the LDAP, Kerberos and syslog server and related
9148 configuration are generated using DNS information at boot. First the
9149 installer looks for a host named ldap in the current DNS domain. If
9150 not found, it looks for _ldap._tcp SRV records in DNS instead. If an
9151 LDAP server is found, its root DSE entry is requested and the
9152 attributes namingContexts and defaultNamingContext are used to
9153 determine which LDAP base to use for NSS. If there are several
9154 namingContexts attibutes and the defaultNamingContext is present, that
9155 LDAP subtree is used as the base. If defaultNamingContext is missing,
9156 the subtrees listed as namingContexts are searched in sequence for any
9157 object with class posixAccount or posixGroup, and the first one with
9158 such an object is used as the LDAP base. For Kerberos, a similar
9159 search is done by first looking for a host named kerberos, and then
9160 for the _kerberos._tcp SRV record. I
've been unable to find a way to
9161 look up the Kerberos realm, so for this the upper case string of the
9162 current DNS domain is used.
</p
>
9164 <p
>For the syslog server, the hosts syslog and loghost are searched
9165 for, and the _syslog._udp SRV record is consulted if no such host is
9166 found. This algorithm works for both Debian Edu and the University of
9167 Oslo. A similar strategy would work for locating the sitesummary
9168 server, but have not been implemented yet. I decided to fetch and
9169 save these settings during installation, to make sure moving to a
9170 different network does not change the set of users being allowed to
9171 log in nor the passwords required to log in. Usernames and passwords
9172 will be cached by sssd when the user logs in on the Debian Edu
9173 network, and will not change as the laptop move around. For a
9174 non-roaming machine, there is no caching, but given that it is
9175 supposed to stay in place it should not matter much. Perhaps we
9176 should switch those to use sssd too?
</p
>
9178 <p
>The user
's SMB mount point for the network home directory is
9179 located when the user logs in for the first time. The LDAP server is
9180 consulted to look for the user
's LDAP object and the sambaHomePath
9181 attribute is used if found. If it isn
't found, the home directory
9182 path fetched from NSS is used instead. Assuming the path is of the
9183 form /site/server/directory/username, the second part is looked up in
9184 DNS and used to generate a SMB URL of the form
9185 smb://server.domain/username. This algorithm works for both Debian
9186 edu and the University of Oslo. Perhaps there are better attributes
9187 to use or a better algorithm that works for more sites, but this will
9188 do for now. :)
</p
>
9190 <p
>This work should make it easier to integrate the Debian Edu clients
9191 into any LDAP/Kerberos infrastructure, and make the current setup even
9192 more flexible than before. I suspect it will also work for thin
9193 client servers, allowing one to easily set up LTSP and hook it into a
9194 existing network infrastructure, but I have not had time to test this
9197 <p
>If you want to help out with implementing these things for Debian
9198 Edu, please contact us on debian-edu@lists.debian.org.
</p
>
9200 <p
>Update
2010-
08-
09: Simon Farnsworth gave me a heads-up on how to
9201 detect Kerberos realm from DNS, by looking for _kerberos TXT entries
9202 before falling back to the upper case DNS domain name. Will have to
9203 implement it for Debian Edu. :)

>A few years ago, I was involved in a project planning to use
9213 Windows file servers as home directory servers for Debian
9214 Edu/Skolelinux machines. This was thought to be no problem, as the
9215 access would be through the SMB network file system protocol, and we
9216 knew other sites used SMB with unix and samba as the file server to
9217 mount home directories without any problems. But, after months of
9218 struggling, we had to conclude that our goal was impossible.
</p
>
9220 <p
>The reason is simply that while SMB can be used for home
9221 directories when the file server is Samba running on Unix, this only
9222 work because of Samba have some extensions and the fact that the
9223 underlying file system is a unix file system. When using a Windows
9224 file server, the underlying file system do not have POSIX semantics,
9225 and several programs will fail if the users home directory where they
9226 want to store their configuration lack POSIX semantics.
</p
>
9228 <p
>As part of this work, I wrote a small C program I want to share
9229 with you all, to replicate a few of the problematic applications (like
9230 OpenOffice.org and GCompris) and see if the file system was working as
9231 it should. If you find yourself in spooky file system land, it might

>A few days ago, I
9444 <a href=
"http://people.skolelinux.org/pere/blog/Debian_Edu_roaming_workstation___at_the_university_of_Oslo.html
">tried
9445 to install
</a
> a Roaming workation profile from Debian Edu/Squeeze
9446 while on the university network here at the University of Oslo, and
9447 noticed how much had to change to get it operational using the
9448 university infrastructure. It was fairly easy, but it occured to me
9449 that Debian Edu would improve a lot if I could get the client to
9450 connect without any changes at all, and thus let the client configure
9451 itself during installation and first boot to use the infrastructure
9452 around it. Now I am a huge step further along that road.
</p
>
9454 <p
>With our current squeeze-test packages, I can select the roaming
9455 workstation profile and get a working laptop connecting to the
9456 university LDAP server for user and group and our active directory
9457 servers for Kerberos authentication. All this without any
9458 configuration at all during installation. My users home directory got
9459 a bookmark in the KDE menu to mount it via SMB, with the correct URL.
9460 In short, openldap and sssd is correctly configured. In addition to
9461 this, the client look for http://wpad/wpad.dat to configure a web
9462 proxy, and when it fail to find it no proxy settings are stored in
9463 /etc/environment and /etc/apt/apt.conf. Iceweasel and KDE is
9464 configured to look for the same wpad configuration and also do not use
9465 a proxy when at the university network. If the machine is moved to a
9466 network with such wpad setup, it would automatically use it when DHCP
9467 gave it a IP address.
</p
>
9469 <p
>The LDAP server is located using DNS, by first looking for the DNS
9470 entry ldap.$domain. If this do not exist, it look for the
9471 _ldap._tcp.$domain SRV records and use the first one as the LDAP
9472 server. Next, it connects to the LDAP server and search all
9473 namingContexts entries for posixAccount or posixGroup objects, and
9474 pick the first one as the LDAP base. For Kerberos, a similar
9475 algorithm is used to locate the LDAP server, and the realm is the
9476 uppercase version of $domain.
</p
>
9478 <p
>So, what is not working, you might ask. SMB mounting my home
9479 directory do not work. No idea why, but suspected the incorrect
9480 Kerberos settings in /etc/krb5.conf and /etc/samba/smb.conf might be
9481 the cause. These are not properly configured during installation, and
9482 had to be hand-edited to get the correct Kerberos realm and server,
9483 but SMB mounting still do not work. :(
</p
>
9485 <p
>With this automatic configuration in place, I expect a Debian Edu
9486 roaming profile installation would be able to automatically detect and
9487 connect to any site using LDAP and Kerberos for NSS directory and PAM
9488 authentication. It should also work out of the box in a Active
9489 Directory environment providing posixAccount and posixGroup objects
9490 with UID and GID values.

>The new roaming workstation profile in Debian Edu/Squeeze is fairly
9503 similar to the laptop setup am I working on using Ubuntu for the
9504 University of Oslo, and just for the heck of it, I tested today how
9505 hard it would be to integrate that profile into the university
9506 infrastructure. In this case, it is the university LDAP server,
9507 Active Directory Kerberos server and SMB mounting from the Netapp file
9510 <p
>I was pleasantly surprised that the only three files needed to be
9511 changed (/etc/sssd/sssd.conf, /etc/ldap.conf and
9512 /etc/mklocaluser.d/
20-debian-edu-config) and one file had to be added
9513 (/usr/share/perl5/Debian/Edu_Local.pm), to get the client working.
9514 Most of the changes were to get the client to use the university LDAP
9515 for NSS and Kerberos server for PAM, but one was to change a hard
9516 coded DNS domain name in the mklocaluser hook from .intern to
9519 <p
>This testing was so encouraging, that I went ahead and adjusted the
9520 Debian Edu scripts and setup in subversion to centralise the roaming
9521 workstation setup a bit more and avoid the hardcoded DNS domain name,
9522 so that when I test this tomorrow, I expect to get away with modifying
9523 only /etc/sssd/sssd.conf and /etc/ldap.conf to get it to use the
9524 university servers.

9526 <p

9527 fetch all their initial setup during installation and first boot, to
9528 allow them to be inserted also into environments where the default

>The last few months me and the other Debian Edu developers have
9660 been working hard to get the Debian/Squeeze based version of Debian
9661 Edu/Skolelinux into shape. This future version will use Kerberos for
9662 authentication, and services are slowly migrated to single signon,
9663 getting rid of password questions one at the time.
</p
>
9665 <p
>It will also feature a roaming workstation profile with local home
9666 directory, for laptops that are only some times on the Skolelinux
9667 network, and for this profile a shortcut is created in Gnome and KDE
9668 to gain access to the users home directory on the file server. This
9669 shortcut uses SMB at the moment, and yesterday I had time to test if
9670 SMB mounting had started working in KDE after we added the cifs-utils
9671 package. I was pleasantly surprised how well it worked.
</p
>
9673 <p
>Thanks to the recent changes to our samba configuration to get it
9674 to use Kerberos for authentication, there were no question about user
9675 password when mounting the SMB volume. A simple click on the shortcut
9676 in the KDE menu, and a window with the home directory popped
9679 <p

9680 Debian Edu. We already had PAM, LDAP, IMAP and SMTP in place, and now
9681 also Samba. Next step is Cups and hopefully also NFS.

9683 <p
>We had planned a alpha0 release of Debian Edu for today, but thanks
9684 to the autobuilder administrators for some architectures being slow to
9685 sign packages, we are still missing the fixed LTSP package we need for
9686 the release. It was uploaded three days ago with urgency=high, and if
9687 it had entered testing yesterday we would have been able to test it in
9688 time for a alpha0 release today. As the binaries for ia64 and powerpc
9689 still not uploaded to the Debian archive, we need to delay the alpha

9727 using the same LDAP objects, and a

9728 reverse entries are in two different subtrees in LDAP with a structure

9732 <p

9948 The object classes need to have fixed names, and the configuration
9949 need to be stored in a fairly specific LDAP structure. On the
9950 positive side, the invidiual dhcpHost entires can be anywhere without
9951 the DN pointed to by the dhcpServer entries. The latter should make
9952 it possible to group all host entries in a subtree next to the
9953 configuration entries, and this subtree can also be shared with the
9954 DNS server if the schema proposed above is combined with the dhcpHost
9955 structural object class.

9967 I guess one could implement ones own schema, as long as the

10021 <description><p
>For a while now, I have wanted to find a way to change the DNS and
10022 DHCP services in Debian Edu to use the same LDAP objects for a given
10023 computer, to avoid the possibility of having a inconsistent state for
10024 a computer in LDAP (as in DHCP but no DNS entry or the other way
10025 around) and make it easier to add computers to LDAP.
</p
>
10027 <p
>I
've looked at how powerdns and dhcpd is using LDAP, and using this
10028 information finally found a solution that seem to work.
</p
>
10030 <p
>The old setup required three LDAP objects for a given computer.
10031 One forward DNS entry, one reverse DNS entry and one DHCP entry. If
10032 we switch powerdns to use its strict LDAP method (ldap-method=strict
10033 in pdns-debian-edu.conf), the forward and reverse DNS entries are
10034 merged into one while making it impossible to transfer the reverse map
10035 to a slave DNS server.
</p
>
10037 <p
>If we also replace the object class used to get the DNS related
10038 attributes to one allowing these attributes to be combined with the
10039 dhcphost object class, we can merge the DNS and DHCP entries into one.
10040 I
've written such object class in the dnsdomainaux.schema file (need
10041 proper OIDs, but that is a minor issue), and tested the setup. It
10042 seem to work.
</p
>
10044 <p
>With this test setup in place, we can get away with one LDAP object
10045 for both DNS and DHCP, and even the LTSP configuration I suggested in
10046 an earlier email. The combined LDAP object will look something like

10064 before asking DNS to resolve the fixed-adddress. LTSP will use
10065 dhcphwaddress or associateddomain and the ldapconfig* attributes.
</p

10067 <p
>I am not yet sure if I can get the DHCP server to look for its
10068 dhcphost in a different location, to allow us to put the objects
10069 outside the
"DHCP Config

10070 that. If I can
't figure out a way to do that, we can still get rid of
10071 the hosts subtree and move all its content into the DHCP Config tree
10072 (which probably should be renamed to be more related to the new
10073 content. I suspect cn=dnsdhcp,ou=services or something like that
10074 might be a good place to put it.

>Vagrant mentioned on IRC today that ltsp_config now support
10087 sourcing files from /usr/share/ltsp/ltsp_config.d/ on the thin
10088 clients, and that this can be used to fetch configuration from LDAP if
10089 Debian Edu choose to store configuration there.
</p
>
10091 <p
>Armed with this information, I got inspired and wrote a test module
10092 to get configuration from LDAP. The idea is to look up the MAC
10093 address of the client in LDAP, and look for attributes on the form
10094 ltspconfigsetting=value, and use this to export SETTING=value to the
10095 LTSP clients.

10098 in a

10099 allowing us to store all information about a computer in one place.

10290 <description><p
>For a laptop, centralized user directories and password checking is
10291 a bit troubling. Laptops are typically used also when not connected
10292 to the network, and it is vital for a user to be able to log in or
10293 unlock the screen saver also when a central server is unavailable.
10294 This is possible by caching passwords and directory information (user
10295 and group attributes) locally, and the packages to do so are available
10296 in Debian. Here follow two recipes to set this up in Debian/Squeeze.
10297 It is also possible to set up in Debian/Lenny, but require more manual
10298 setup there because pam-auth-update is missing in Lenny.
</p
>
10300 <h2
>LDAP/Kerberos + nscd + libpam-ccreds + libpam-mklocaluser/pam_mkhomedir
</h2
>
10302 This is the traditional method with a twist. The password caching is
10303 provided by libpam-ccreds (version
10-
4 or later is needed on
10304 Squeeze), and the directory caching is done by nscd. The directory
10305 lookup and password checking is done using LDAP. If one want to use
10306 Kerberos for password checking the libpam-ldapd package can be
10307 replaced with libpam-krb5 or libpam-heimdal. If one is happy having a
10308 local home directory with the path listed in LDAP, one can use the
10309 pam_mkhomedir module from pam-modules to make this happen instead of
10310 using libpam-mklocaluser. A setup for pam-auth-update to enable
10311 pam_mkhomedir will have to be written until a fix for
10312 <a href=
"http://bugs.debian.org/
568577">bug #
568577</a
> is in the
10313 archive. Because I believe it is a bad idea to have local home
10314 directories using misleading paths like /site/server/partition/, I
10315 prefer to create a local user with the home directory in /home/. This
10316 is done using the libpam-mklocaluser package.

10432 libpam-ccreds. It support LDAP and Kerberos, but not NIS. Version
10433 1.2 do not support netgroups, but it is said that it will support this

10496 <description><p
>The last few days I have been looking into the status of the LDAP
10497 directory in Debian Edu, and in the process I started to miss a GUI
10498 tool to browse the LDAP tree. The only one I was able to find in
10499 Debian/Squeeze and Lenny is
10500 <a href=
"http://luma.sourceforge.net/
">LUMA
</a
>, which has proved to
10501 be a great tool to get a overview of the current LDAP directory
10502 populated by default in Skolelinux. Thanks to it, I have been able to
10503 find empty and obsolete subtrees, misplaced objects and duplicate
10504 objects. It will be installed by default in Debian/Squeeze. If you
10505 are working with LDAP, give it a go. :)
</p
>
10507 <p
>I did notice one problem with it I have not had time to report to
10508 the BTS yet. There is no .desktop file in the package, so the tool do
10509 not show up in the Gnome and KDE menus, but only deep down in in the
10510 Debian submenu in KDE. I hope that can be fixed before Squeeze is
10511 released.
</p
>
10513 <p
>I have not yet been able to get it to modify the tree yet. I would
10514 like to move objects and remove subtrees directly in the GUI, but have
10515 not found a way to do that with LUMA yet. So in the mean time, I use
10516 <a href=
"http://www.lichteblau.com/ldapvi/
">ldapvi
</a
> for that.
</p
>
10518 <p
>If you have tips on other GUI tools for LDAP that might be useful
10519 in Debian Edu, please contact us on debian-edu@lists.debian.org.

29: Ross Reedstrom tipped us about the
10522 <a href=
"http://packages.qa.debian.org/g/gq.html
">gq
</a
> package as a
10523 useful GUI alternative. It seem like a good tool, but is unmaintained
10524 in Debian and got a RC bug keeping it out of Squeeze. Unless that
10525 changes, it will not be an option for Debian Edu based on Squeeze.

10535 <a href=
"http://people.skolelinux.org/pere/blog/Time_for_new__LDAP_schemas_replacing_RFC_2307_.html
">complained
10536 about the fact
</a

10537 for storing DNS and DHCP information in LDAP to combine the two sets
10538 of information into one LDAP object representing a computer.
</p
>
10540 <p
>In the mean time, I discovered that a simple fix would be to make
10541 the dhcpHost object class auxiliary, to allow it to be combined with
10542 the dNSDomain object class, and thus forming one object for one
10543 computer when storing both DHCP and DNS information in LDAP.
</p

10545 <p
>If I understand this correctly, it is not safe to do this change
10546 without also changing the assigned number for the object class, and I
10547 do not know enough about LDAP schema design to do that properly for
10548 Debian Edu.

10586 of Debian upgrades
</a

've
10587 finally made the upgrade logs available from
10588 <a href=
"http://people.skolelinux.org/pere/debian-upgrade-testing/
">http://people.skolelinux.org/pere/debian-upgrade-testing/
</a
>.
10589 I am now testing dist-upgrade of Gnome and KDE in a chroot using both
10590 apt and aptitude, and found their differences interesting. This time
10591 I will only focus on their removal plans.
</p
>
10593 <p
>After installing a Gnome desktop and the laptop task, apt-get wants
10594 to remove
72 packages when dist-upgrading from Lenny to Squeeze. The
10595 surprising part is that it want to remove xorg and all
10596 xserver-xorg-video* drivers. Clearly not a good choice, but I am not
10597 sure why. When asking aptitude to do the same, it want to remove
129
10598 packages, but most of them are library packages I suspect are no
10599 longer needed. Both of them want to remove bluetooth packages, which
10600 I do not know. Perhaps these bluetooth packages are obsolete?
</p
>
10602 <p
>For KDE, apt-get want to remove
82 packages, among them kdebase
10603 which seem like a bad idea and xorg the same way as with Gnome. Asking
10604 aptitude for the same, it wants to remove
192 packages, none which are
10605 too surprising.
</p
>
10607 <p
>I guess the removal of xorg during upgrades should be investigated
10608 and avoided, and perhaps others as well. Here are the complete list
10609 of planned removals. The complete logs is available from the URL
10610 above. Note if you want to repeat these tests, that the upgrade test
10611 for kde+apt-get hung in the tasksel setup because of dpkg asking
10612 conffile questions. No idea why. I worked around it by using
10613 '<tt
>echo
>> /proc/
<em
>pidofdpkg
</em
>/fd/
0</tt
>' to tell dpkg to
10614 continue.

10760 <description><p
>The last few days I have done some upgrade testing in Debian, to
10761 see if the upgrade from Lenny to Squeeze will go smoothly. A few bugs
10762 have been discovered and reported in the process
10763 (
<a href=
"http://bugs.debian.org/
585410">#
585410</a
> in nagios3-cgi,
10764 <a href=
"http://bugs.debian.org/
584879">#
584879</a
> already fixed in
10765 enscript and
<a href=
"http://bugs.debian.org/
584861">#
584861</a
> in
10766 kdebase-workspace-data), and to get a more regular testing going on, I
10767 am working on a script to automate the test.
</p
>
10769 <p
>The idea is to create a Lenny chroot and use tasksel to install a
10770 Gnome or KDE desktop installation inside the chroot before upgrading
10771 it. To ensure no services are started in the chroot, a policy-rc.d
10772 script is inserted. To make sure tasksel believe it is to install a
10773 desktop on a laptop, the tasksel tests are replaced in the chroot
10774 (only acceptable because this is a throw-away chroot).
</p
>
10776 <p
>A naive upgrade from Lenny to Squeeze using aptitude dist-upgrade
10777 currently always fail because udev refuses to upgrade with the kernel
10778 in Lenny, so to avoid that problem the file /etc/udev/kernel-upgrade
10779 is created. The bug report
10780 <a href=
"http://bugs.debian.org/
566000">#
566000</a
> make me suspect
10781 this problem do not trigger in a chroot, but I touch the file anyway
10782 to make sure the upgrade go well. Testing on virtual and real
10783 hardware have failed me because of udev so far, and creating this file
10784 do the trick in such settings anyway. This is a
10785 <a href=
"http://www.linuxquestions.org/questions/debian-
26/failed-dist-upgrade-due-to-udev-config_sysfs_deprecated-nonsense-
804130/
">known
10786 issue
</a
> and the current udev behaviour is intended by the udev
10787 maintainer because he lack the resources to rewrite udev to keep
10788 working with old kernels or something like that. I really wish the
10789 udev upstream would keep udev backwards compatible, to avoid such
10790 upgrade problem, but given that they fail to do so, I guess
10791 documenting the way out of this mess is the best option we got for
10792 Debian Squeeze.

10919 Skolelinux-arkitekturen er laget for sentralisert drift og plassering
10920 av tjenerne lokalt eller sentralt alt etter behov og nettkapasitet.
10921 Den er modellert på nettverks- og tjenerløsningen som brukes på
10922 Universitetet i Tromsø og Oslo, der jeg jobber med utvikling av
10923 driftstjenester. Dette er det heldigvis noen som har fått med seg, og
10924 jeg er glad for å kunne sitere fra en kommentar på den overnevnte
10925 artikkelen. Min venn og gamle kollega Sturle Sunde forteller der:
10928 <p
>I Flora kommune køyrer vi Skulelinux på skular med alt frå
15 til
10929 meir enn
500 elevar. Dei store skulane har eigen tenar, for det er
10930 mest praktisk. Eg, som er driftsansvarleg for heile nettet, ser
10931 sjeldan dei tenarane fysisk, men at dei står der gjer skulane mindre
10932 avhengige av eksterne linjer som er trege eller dyre. Dei minste
10933 skulane har ikkje eigen tenar. Å bruke sentral tenar er heller ikkje
10934 noko problem. Småskulane klarar seg fint med
1 mbit-linje til ein
10935 sentral tenar eller tenaren på ein større skule.
</p
>
10937 <p
>Det beste med Skulelinux er halvtjukke klientar. Dei treng ikkje
10938 harddisk og brukar minimalt med ressursar på tenaren fordi dei køyrer
10939 programma lokalt. Eit klasserom med
30 sju-åtte år gamle maskiner har
10940 mykje meir CPU og RAM totalt enn nokon moderne tenar til under
10941 millionen. Det trengst to kommandoar på den sentrale tenaren for å
10942 oppdatere alle klientane, både tynne og halvtjukke. Vi har ingen
10943 problem med diskar som ryk heller, som var eit problem før fordi
10944 elevane sat og sparka i maskinene. Og dei krev lite bandbreidde i
10945 nettet, so det er fullt mogleg å køyre slike på småskular med trege
10946 linjer mot tenaren på ein større skule.
</p
>
10948 <p
>Flora kommune har nesten
800 Linux-maskiner i sitt skulenett, og
10949 ein person som tek seg av drift av heile nettet, inkludert tenarar,
10950 klientar, operativsystem, programvare, heimekontorløysing og
10951 administrasjon av brukarar.

10953 <p
>No skal det seiast at vi ikkje køyrer rein Skulelinux ut av
10954 boksen. Vi har gjort ein del tilpassingar mot noko Novell-greier som
10955 var der frå før, og som har komplisert installasjonen vår. Etter at

>After a long break from debian-installer development, I finally
11105 found time today to return to the project. Having to spend less time
11106 working dependency based boot in debian, as it is almost complete now,
11107 definitely helped freeing some time.
</p

11109 <p
>A while back, I ran into a problem while working on Debian Edu. We
11110 include some firmware packages on the Debian Edu CDs, those needed to
11111 get disk and network controllers working. Without having these
11112 firmware packages available during installation, it is impossible to
11113 install Debian Edu on the given machine, and because our target group
11114 are non-technical people, asking them to provide firmware packages on
11115 an external medium is a support pain. Initially, I expected it to be
11116 enough to include the firmware packages on the CD to get
11117 debian-installer to find and use them. This proved to be wrong.
11118 Next, I hoped it was enough to symlink the relevant firmware packages
11119 to some useful location on the CD (tried /cdrom/ and
11120 /cdrom/firmware/). This also proved to not work, and at this point I
11121 found time to look at the debian-installer code to figure out what was
11122 going to work.
</p
>
11124 <p
>The firmware loading code is in the hw-detect package, and a closer
11125 look revealed that it would only look for firmware packages outside
11126 the installation media, so the CD was never checked for firmware
11127 packages. It would only check USB sticks, floppies and other
11128 "external
" media devices. Today I changed it to also look in the
11129 /cdrom/firmware/ directory on the mounted CD or DVD, which should
11130 solve the problem I ran into with Debian edu. I also changed it to
11131 look in /firmware/, to make sure the installer also find firmware
11132 provided in the initrd when booting the installer via PXE, to allow us
11133 to provide the same feature in the PXE setup included in Debian
11136 <p
>To make sure firmware deb packages with a license questions are not
11137 activated without asking if the license is accepted, I extended
11138 hw-detect to look for preinst scripts in the firmware packages, and
11139 run these before activating the firmware during installation. The
11140 license question is asked using debconf in the preinst, so this should
11141 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
11154 Edu finally entered the Debian archive. Today, the new
11155 <a href=

">libpam-mklocaluser

11159 package needed by libpam-mklocaluser, and the
11160 <a href=
"http://packages.qa.debian.org/s/sssd.html
">sssd
</a

11161 passed NEW on Monday. In addition, the
11162 <a href=
"http://packages.qa.debian.org/libp/libpam-ccreds.html
">libpam-ccreds
</a
>
11163 package we need is in experimental (version
10-
4) since Saturday, and
11164 hopefully will be moved to unstable soon.
</p
>
11166 <p
>This collection of packages allow for two different setups for
11167 roaming laptops. The traditional setup would be using libpam-ccreds,
11168 nscd and libpam-mklocaluser with LDAP or Kerberos authentication,
11169 which should work out of the box if the configuration changes proposed
11170 for nscd in
<a href=
"http://bugs.debian.org/
485282">BTS report
11171 #
485282</a
> is implemented. The alternative setup is to use sssd with
11172 libpam-mklocaluser to connect to LDAP or Kerberos and let sssd take
11173 care of the caching of passwords and group information.
</p
>
11175 <p
>I have so far been unable to get sssd to work with the LDAP server
11176 at the University, but suspect the issue is some SSL/GnuTLS related
11177 problem with the server certificate. I plan to update the Debian
11178 package to version
1.2, which is scheduled for next week, and hope to
11179 find time to make sure the next release will include both the
11180 Debian/Ubuntu specific patches. Upstream is friendly and responsive,
11181 and I am sure we will find a good solution.
</p
>
11183 <p
>The idea is to set up the roaming laptops to authenticate using
11184 LDAP or Kerberos and create a local user with home directory in /home/
11185 when a usre in LDAP logs in via KDM or GDM for the first time, and
11186 cache the password for offline checking, as well as caching group
11187 memberhips and other relevant LDAP information. The
11188 libpam-mklocaluser package was created to make sure the local home
11189 directory is in /home/, instead of /site/server/directory/ which would
11190 be the home directory if pam_mkhomedir was used. To avoid confusion
11191 with support requests and configuration, we do not want local laptops
11192 to have users in a path that is used for the same users home directory
11193 on the home directory servers.
</p
>
11195 <p
>One annoying problem with gdm is that it do not show the PAM
11196 message passed to the user from libpam-mklocaluser when the local user
11197 is created. Instead gdm simply reject the login with some generic
11198 message. The message is shown in kdm, ssh and login, so I guess it is
11199 a bug in gdm. Have not investigated if there is some other message
11200 type that can be used instead to get gdm to also show the message.

11357 <description><p
>For some years now, I have wondered how we should handle laptops in
11358 Debian Edu. The Debian Edu infrastructure is mostly designed to
11359 handle stationary computers, and less suited for computers that come
11362 <p
>Now I finally believe I have an sensible idea on how to adjust
11363 Debian Edu for laptops, by introducing a new profile for them, for
11364 example called Roaming Workstations. Here are my thought on this.
11365 The setup would consist of the following:
</p
>
11369 <li
>During installation, the user name of the owner / primary user of
11370 the laptop is requested and a local home directory is set up for
11371 the user, with uid and gid information fetched from the LDAP
11372 server. This allow the user to work also when offline. The
11373 central home directory can be available in a subdirectory on
11374 request, for example mounted via CIFS. It could be mounted
11375 automatically when a user log in while on the Debian Edu network,
11376 and unmounted when the machine is taken away (network down,
11377 hibernate, etc), it can be set up to do automatic mounting on
11378 request (using autofs), or perhaps some GUI button on the desktop
11379 can be used to access it when needed. Perhaps it is enough to use
11380 the fish protocol in KDE?
</li
>
11382 <li
>Password checking is set up to use LDAP or Kerberos
11383 authentication when the machine is on the Debian Edu network, and
11384 to cache the password for offline checking when the machine unable
11385 to reach the LDAP or Kerberos server. This can be done using
11386 <a href=
"http://www.padl.com/OSS/pam_ccreds.html
">libpam-ccreds
</a
>
11387 or the Fedora developed
11388 <a href=
"https://fedoraproject.org/wiki/Features/SSSD
">System
11389 Security Services Daemon
</a
> packages.
</li
>
11391 <li
>File synchronisation with the central home directory is set up
11392 using a shared directory in both the local and the central home
11393 directory, using unison.
</li
>
11395 <li
>Printing should be set up to print to all printers broadcasting
11396 their existence on the local network, and should then work out of
11397 the box with CUPS. For sites needing accurate printer quotas, some
11398 system with Kerberos authentication or printing via ssh could be
11399 implemented.
</li
>
11401 <li
>For users that should have local root access to their laptop,
11402 sudo should be used to allow this to the local user.
</li
>
11404 <li
>It would be nice if user and group information from LDAP is
11405 cached on the client, but given that there are entries for the
11406 local user and primary group in /etc/, it should not be needed.
</li
>
11410 <p
>I believe all the pieces to implement this are in Debian/testing at
11411 the moment. If we work quickly, we should be able to get this ready
11412 in time for the Squeeze release to freeze. Some of the pieces need
11413 tweaking, like libpam-ccreds should get support for pam-auth-update
11414 (
<a href=
"http://bugs.debian.org/
566718">#
566718</a
>) and nslcd (or
11415 perhaps debian-edu-config) should get some integration code to stop
11416 its daemon when the LDAP server is unavailable to avoid long timeouts
11417 when disconnected from the net. If we get Kerberos enabled, we need
11418 to make sure we avoid long timeouts there too.

11431 NUUG presentation
</a
> about Kerberos was inspiring, and reminded me
11432 about the need to start using Kerberos in Skolelinux. Setting up a
11433 Kerberos server seem to be straight forward, and if we get this in
11434 place a long time before the Squeeze version of Debian freezes, we
11435 have a chance to migrate Skolelinux away from NFSv3 for the home
11436 directories, and over to an architecture where the infrastructure do
11437 not have to trust IP addresses and machines, and instead can trust
11438 users and cryptographic keys instead.
</p
>
11440 <p
>A challenge will be integration and administration. Is there a
11441 Kerberos implementation for Debian where one can control the
11442 administration access in Kerberos using LDAP groups? With it, the
11443 school administration will have to maintain access control using flat
11444 files on the main server, which give a huge potential for errors.
</p
>
11446 <p
>A related question I would like to know is how well Kerberos and
11447 pam-ccreds (offline password check) work together. Anyone know?
</p
>
11449 <p
>Next step will be to use Kerberos for access control in Lwat and
11450 Nagios. I have no idea how much work that will be to implement. We
11451 would also need to document how to integrate with Windows AD, as such
11452 shared network will require two Kerberos realms that need to cooperate
11453 to work properly.
</p
>
11455 <p
>I believe a good start would be to start using Kerberos on the
11456 skolelinux.no machines, and this way get ourselves experience with
11457 configuration and integration. A natural starting point would be
11458 setting up ldap.skolelinux.no as the Kerberos server, and migrate the
11459 rest of the machines from PAM via LDAP to PAM via Kerberos one at the
11462 <p
>If you would like to contribute to get this working in Skolelinux,
11463 I recommend you to see the video recording from yesterdays NUUG
11464 presentation, and start using Kerberos at home. The video show show
11465 up in a few days.

>6 years ago, as part of the Debian Edu development I am involved

11477 package in
2004 (
<a href=

11478 and revisited every time Debian Edu was working on a new release.
11479 Today, this finally paid off.

11481 <p
>The framework for this feature was today commited to the git
11482 repositry for the xorg package, and the git repository for xdm has
11483 been updated to use this framework. Next on my agenda is to make sure
11484 kdm and gdm also add code to use this framework.
</p

11486 <p
>In Debian Edu, we want to ability to run commands as root when the
11487 user log out, to get rid of runaway processes and do general cleanup
11488 after a user. With this framework in place, we finally can do that in
11489 a generic way that work with all display managers using this
11490 framework. My goal is to get all display managers in Debian use it,
11491 similar to how they use the Xsession.d framework today.

11513 and have just a few weeks or months to make it happen.

>One of the new features in the next Debian/Lenny based release of
11523 Debian Edu/Skolelinux, which is scheduled for release in the next few
11524 days, is automatic configuration of the service monitoring system
11525 Nagios. The previous release had automatic configuration of trend
11526 analysis using Munin, and this Lenny based release take that a step
11529 <p
>When installing a Debian Edu Main-server, it is automatically
11530 configured as a Munin and Nagios server. In addition, it is
11531 configured to be a server for the
11532 <a href=
"http://wiki.debian.org/DebianEdu/HowTo/SiteSummary
">SiteSummary
11533 system
</a
> I have written for use in Debian Edu. The SiteSummary
11534 system is inspired by a system used by the University of Oslo where I
11535 work. In short, the system provide a centralised collector of
11536 information about the computers on the network, and a client on each
11537 computer submitting information to this collector. This allow for
11538 automatic information on which packages are installed on each machine,
11539 which kernel the machines are using, what kind of configuration the
11540 packages got etc. This also allow us to automatically generate Munin
11541 and Nagios configuration.
</p
>
11543 <p
>All computers reporting to the sitesummary collector with the
11544 munin-node package installed is automatically enabled as a Munin
11545 client and graphs from the statistics collected from that machine show
11546 up automatically on http://www/munin/ on the Main-server.
</p
>
11548 <p
>All non-laptop computers reporting to the sitesummary collector are
11549 automatically monitored for network presence (ping and any network
11550 services detected). In addition, all computers (also laptops) with
11551 the nagios-nrpe-server package installed and configured the way
11552 sitesummary would configure it, are monitored for full disks, software
11553 raid status, swap free and other checks that need to run locally on
11554 the machine.
</p
>
11556 <p
>The result is that the administrator on a school using Debian Edu
11557 based on Lenny will be able to check the health of his installation
11558 with one look at the Nagios settings, without having to spend any time
11559 keeping the Nagios configuration up-to-date.
</p
>
11561 <p
>The only configuration one need to do to get Nagios up and running
11562 is to set the password used to get access via HTTP. The system
11563 administrator need to run
"<tt
>htpasswd /etc/nagios3/htpasswd.users
11564 nagiosadmin
</tt
>" to create a nagiosadmin user and set a password for
11565 it to be able to log into the Nagios web pages. After that,
11566 everything is taken care of.

11580 å få fri programvare og unix-lignende operativsystemer inn i Skolen.
11581 Tanken var at en måtte starte med lærerne for at ungene skulle få
11582 mulighet til å møte en bedre IT-hverdag. Jeg var tilstede på
11583 møtet, og hadde sans for ideen, men intet skjedde. På vårparten
11584 2001 ble det arrangert en demonstrasjon i anledning at First Tuesday
11585 hadde invitert Microsoft til et møte for å fortelle om fremtidens

11591 Etter demonstrasjonen arrangerte Håkon en fest hjemme hos seg der alle
11592 som hadde vært aktive i demonstrasjonsplanlegging og gjennomføringen
11593 deltok. Før festen var jeg blitt lei av å vente på at Håkon skulle ta
11594 initiativ til

11595 besteme jeg meg for å benytte anledningen hos Håkon til å snakke om
11596 behovet for å hjelpe skolene i gang med bedre datasystemer bestående
11597 av fri programvare og unix-lignende operativsystemer. Flere var
11598 interessert, og Knut Yrvin tenkte på ideen. Han

'm sitting on the train going home from this weekends Debian
11636 Edu/Skolelinux development gathering. I got a bit done tuning the
11637 desktop, and looked into the dynamic service location protocol
11638 implementation avahi. It look like it could be useful for us. Almost
11639 30 people participated, and I believe it was a great environment to
11640 get to know the Skolelinux system. Walter Bender, involved in the
11641 development of the Sugar educational platform, presented his stuff and
11642 also helped me improve my OLPC installation. He also showed me that
11643 his Turtle Art application can be used in standalone mode, and we
11644 agreed that I would help getting it packaged for Debian. As a
11645 standalone application it would be great for Debian Edu. We also
11646 tried to get the video conferencing working with two OLPCs, but that
11647 proved to be too hard for us. The application seem to need more work
11648 before it is ready for me. I look forward to getting home and relax

>The state of standardized LDAP schemas on Linux is far from
11659 optimal. There is RFC
2307 documenting one way to store NIS maps in
11660 LDAP, and a modified version of this normally called RFC
2307bis, with
11661 some modifications to be compatible with Active Directory. The RFC
11662 specification handle the content of a lot of system databases, but do
11663 not handle DNS zones and DHCP configuration.

11666 we would like to store information about users, SMB clients/hosts,
11667 filegroups, netgroups (users and hosts), DHCP and DNS configuration,
11668 and LTSP configuration in LDAP. These objects have a lot in common,
11669 but with the current LDAP schemas it is not possible to have one
11670 object per entity. For example, one need to have at least three LDAP
11671 objects for a given computer, one with the SMB related stuff, one with
11672 DNS information and another with DHCP information. The schemas
11673 provided for DNS and DHCP are impossible to combine into one LDAP
11674 object. In addition, it is impossible to implement quick queries for
11675 netgroup membership, because of the way NIS triples are implemented.
11676 It just do not scale. I believe it is time for a few RFC
11677 specifications to cleam up this mess.

11682 It need to be efficently stored to make sure it scale well.

11722 gjort det umulig å få med ord med bindestrek i

11724 kunne godtas av stavekontrollen. Hadde litt tid til overs å bruke på
11725 stavekontrollen, og satte meg ned med to kopier av byggsystemet og en
11726 liten testdatafil, og byttet ut - med = på utvalgte steder i
11727 byggsystemet og datafilen helt til jeg fikk samme resultat med det
11728 gamle og det nye byggsystemet. Dette tror jeg var forsøk
4, der de
11729 foregående har feilet uten at jeg klarte å forstå hvorfor. Det sier
11730 kanskje litt om kompleksiteten i det originale byggsystemet som Rune

>Recently I have spent some time evaluating the multimedia browser
11772 plugins available in Debian Lenny, to see which one we should use by
11773 default in Debian Edu. We need an embedded video playing plugin with
11774 control buttons to pause or stop the video, and capable of streaming
11775 all the multimedia content available on the web. The test results and
11776 notes are available on
11777 <a href=
"http://wiki.debian.org/DebianEdu/BrowserMultimedia

11778 Debian wiki
</a

11779 fill this need. My personal video player favorite, VLC, has a really
11780 bad plugin which fail on a lot of the test pages. A lot of the MIME
11781 types I would expect to work with any free software player (like
11782 video/ogg), just do not work. And simple formats like the
11783 audio/x-mplegurl format (m3u playlists), just isn
't supported by the
11784 totem and vlc plugins. I hope the situation will improve soon. No
11785 wonder sites use the proprietary Adobe flash to play video.
