19 The Debian Edu Team is pleased to announce the release of Debian Edu
20 Jessie
8.0+edu0~alpha0
22 Debian Edu is a complete operating system for schools. Through its
23 various installation profiles you can install servers, workstations
24 and laptops which will work together on the school network. With
25 Debian Edu, the teachers themselves or their technical support can
26 roll out a complete multi-user multi-machine study environment within
27 hours or a few days. Debian Edu comes with hundreds of applications
28 pre-installed, but you can always add more packages from Debian.
30 For those who want to give Debian Edu Jessie a try, download and
31 installation instructions are available, including detailed
32 instructions in the manual[
1] explaining the first steps, such as
33 setting up a network or adding users. Please note that the password
34 for the user your prompted for during installation must have a length
35 of at least
5 characters!

39 Would you like to give your school
's computer a longer life? Are you
40 tired of sneaker administration, running from computer to computer
41 reinstalling the operating system? Would you like to administrate all
42 the computers in your school using only a couple of hours every week?
43 Check out Debian Edu Jessie!
45 Skolelinux is used by at least two hundred schools all over the world,
46 mostly in Germany and Norway.
48 About Debian Edu and Skolelinux
49 ===============================
51 Debian Edu, also known as Skolelinux[
2], is a Linux distribution based
52 on Debian providing an out-of-the box environment of a completely
53 configured school network. Immediately after installation a school
54 server running all services needed for a school network is set up just
55 waiting for users and machines being added via GOsa², a comfortable
56 Web-UI. A netbooting environment is prepared using PXE, so after
57 initial installation of the main server from CD or USB stick all other
58 machines can be installed via the network. The provided school server
59 provides LDAP database and Kerberos authentication service,
60 centralized home directories, DHCP server, web proxy and many other
61 services. The desktop contains more than
60 educational software
62 packages[
3] and more are available from the Debian archive, and
63 schools can choose between KDE, Gnome, LXDE, Xfce and MATE desktop

205 Edu on machines with disk (and a few other services perhaps to small

207 the Jessie based version, trying to get everything in shape before the

"https://wiki.debian.org/DebianEdu/Status/Jessie

211 status
</a
> can be seen on the Debian wiki, and there is still heaps of
212 work left. Some fatal problems block testing, breaking the installer,
213 but it is possible to work around these to get anyway. Here is a
214 recipe on how to get the installation limping along.
</p
>
216 <p
>First, download the test ISO via
217 <a href=
"ftp://ftp.skolelinux.no/cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-
1.iso
">ftp

>
220 ftp.skolelinux.org::cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-
1.iso).
221 The ISO build was broken on Tuesday, so we do not get a new ISO every
222 12 hours or so, but thankfully the ISO we already got we are able to
223 install with some tweaking.
</p
>
225 <p
>When you get to the Debian Edu profile question, go to tty2
226 (use Alt-Ctrl-F2), run
</p
>
228 <p
><blockquote
><pre
>
229 nano /usr/bin/edu-eatmydata-install
230 </pre
></blockquote
></p
>
232 <p
>and add
'exit
0' as the second line, disabling the eatmydata
233 optimization. Return to the installation, select the profile you want
234 and continue. Without this change, exim4-config will fail to install
235 due to a known bug in eatmydata.
</p
>
237 <p
>When you get the grub question at the end, answer /dev/sda (or if
238 this do not work, figure out what your correct value would be. All my
239 test machines need /dev/sda, so I have no advice if it do not fit
242 <p
>If you installed a profile including a graphical desktop, log in as
243 root after the initial boot from hard drive, and install the
244 education-desktop-XXX metapackage. XXX can be kde, gnome, lxde, xfce
245 or mate. If you want several desktop options, install more than one
246 metapackage. Once this is done, reboot and you should have a working
247 graphical login screen. This workaround should no longer be needed
248 once the education-tasks package version
1.801 enter testing in two
251 <p
>I believe the ISO build will start working on two days when the new
252 tasksel package enter testing and Steve McIntyre get a chance to
253 update the debian-cd git repository. The eatmydata, grub and desktop
254 issues are already fixed in unstable and testing, and should show up
255 on the ISO as soon as the ISO build start working again. Well the
256 eatmydata optimization is really just disabled. The proper fix
257 require an upload by the eatmydata maintainer applying the patch
258 provided in bug
<a href=
"https://bugs.debian.org/
702711">#
702711</a
>.
259 The rest have proper fixes in unstable.
</p
>
261 <p
>I hope this get you going with the installation testing, as we are
262 quickly running out of time trying to get our Jessie based
263 installation ready before the distribution freeze in a month.

<a href=

273 a lot quicker. When we install more than
2000 packages in
274 <a href=
"http://www.skolelinux.org/
">Skolelinux / Debian Edu
</a
> using
275 tasksel in the installer, unpacking the binary packages take forever.
276 A part of the slow I/O issue was discussed in
277 <a href=
"https://bugs.debian.org/
613428">bug #
613428</a
> about too
278 much file system sync-ing done by dpkg, which is the package
279 responsible for unpacking the binary packages. Other parts (like code
280 executed by postinst scripts) might also sync to disk during
281 installation. All this sync-ing to disk do not really make sense to
282 me. If the machine crash half-way through, I start over, I do not try
283 to salvage the half installed system. So the failure sync-ing is
284 supposed to protect against, hardware or system crash, is not really
285 relevant while the installer is running.
</p
>
287 <p
>A few days ago, I thought of a way to get rid of all the file
288 system sync()-ing in a fairly non-intrusive way, without the need to
289 change the code in several packages. The idea is not new, but I have
290 not heard anyone propose the approach using dpkg-divert before. It
291 depend on the small and clever package
292 <a href=
"https://packages.qa.debian.org/eatmydata
">eatmydata
</a
>, which
293 uses LD_PRELOAD to replace the system functions for syncing data to
294 disk with functions doing nothing, thus allowing programs to live
295 dangerous while speeding up disk I/O significantly. Instead of
296 modifying the implementation of dpkg, apt and tasksel (which are the
297 packages responsible for selecting, fetching and installing packages),
298 it occurred to me that we could just divert the programs away, replace
299 them with a simple shell wrapper calling
300 "eatmydata
&nbsp;$program
&nbsp;$@
", to get the same effect.
301 Two days ago I decided to test the idea, and wrapped up a simple
302 implementation for the Debian Edu udeb.
</p
>
304 <p
>The effect was stunning. In my first test it reduced the running
305 time of the pkgsel step (installing tasks) from
64 to less than
44
306 minutes (
20 minutes shaved off the installation) on an old Dell
307 Latitude D505 machine. I am not quite sure what the optimised time
308 would have been, as I messed up the testing a bit, causing the debconf
309 priority to get low enough for two questions to pop up during
310 installation. As soon as I saw the questions I moved the installation
311 along, but do not know how long the question were holding up the
312 installation. I did some more measurements using Debian Edu Jessie,
313 and got these results. The time measured is the time stamp in
314 /var/log/syslog between the
"pkgsel: starting tasksel
" and the
315 "pkgsel: finishing up
" lines, if you want to do the same measurement
316 yourself. In Debian Edu, the tasksel dialog do not show up, and the
317 timing thus do not depend on how quickly the user handle the tasksel

366 <p
>The test is done using a netinst ISO on a USB stick, so some of the
367 time is spent downloading packages. The connection to the Internet
368 was
100Mbit/s during testing, so downloading should not be a
369 significant factor in the measurement. Download typically took a few
370 seconds to a few minutes, depending on the amount of packages being
373 <p
>The speedup is implemented by using two hooks in
374 <a href=
"https://www.debian.org/devel/debian-installer/
">Debian
375 Installer
</a
>, the pre-pkgsel.d hook to set up the diverts, and the
376 finish-install.d hook to remove the divert at the end of the
377 installation. I picked the pre-pkgsel.d hook instead of the
378 post-base-installer.d hook because I test using an ISO without the
379 eatmydata package included, and the post-base-installer.d hook in
380 Debian Edu can only operate on packages included in the ISO. The
381 negative effect of this is that I am unable to activate this
382 optimization for the kernel installation step in d-i. If the code is
383 moved to the post-base-installer.d hook, the speedup would be larger
384 for the entire installation.

've implemented this in the

388 git repository, and plan to provide the optimization as part of the
389 Debian Edu installation. If you want to test this yourself, you can
390 create two files in the installer (or in an udeb). One shell script
391 need do go into /usr/lib/pre-pkgsel.d/, with content like this:

'm not aware of any, but I
464 guess we will see if the change is safe after some more testing.
465 Perhaps there is some package in Debian depending on sync() and
466 fsync() having effect? Perhaps it should go into its own udeb, to

489 schools,
<a href=
"http://www.skolelinux.org/
">Debian Edu /
490 Skolelinux
</a
>, is used quite a lot in Germany, and one of the people
491 involved is Bernd Zeitzen, who show up on the project mailing lists
492 from time to time with interesting questions and tips on how to adjust
493 the setup. I managed to interview him this summer.
</p

495 <p

>Who are you, and how do you spend your days?
</strong
></p
>
497 <p
>My name is Bernd Zeitzen and I
'm married with Hedda, a self
498 employed physiotherapist. My former profession is tool maker, but I
499 haven
't worked for
30 years in this job.
30 years ago I started to
500 support my wife and become her officeworker and a few years later the
501 administrator for a small computer network, today based on Ubuntu
502 Server (Samba, OpenVPN). For her daily work she has to use Windows
503 Desktops because the software she needs to organize her business only
504 works with Windows . :-(
</p
>
506 <p
>In
1988 we started with one PC and DOS, then I learned to use
507 Windows
98,
2000, XP, …,
8, Ubuntu, MacOSX. Today we are running a
508 Linux server with
6 Windows clients and
10 persons (teacher of
509 children with special needs, speech therapist, occupational therapist,
510 psychologist and officeworkers) using our Samba shares via OpenVPN to
511 work with the documentations of our patients.
</p
>
513 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
514 project?
</strong
></p
>
516 <p
>Two years ago a friend of mine asked me, if I want to get a job in
517 his school (
<a href=
"http://www.gymnasium-harsewinkel.de/
">Gymnasium
518 Harsewinkel
</a
>). They started with Skolelinux / Debian Edu and they
519 were looking for people to give support to the teachers using the
520 software and the network and teaching the pupils increasing their
521 computer skills in optional lessons. I
'm spending
4-
6 hours a week
522 with this job.
</p
>
524 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
525 Edu?
</strong
></p
>
527 <p
>The independence.
</p
>
529 <p
>First: Every person is allowed to use, share and develop the
530 software. Even if you are poor, you are allowed to use the software
531 included in Skolelinux/Debian Edu and all the other Free Software.
</p
>
533 <p
>Second: The software runs on old machines and this gives us the
534 possibility to recycle computers, weeded out from offices. The
535 servers and desktops are running for more than two years and they are
536 working reliable.
</p
>
538 <p
>We have two servers (one tjener and one terminal server),
45
539 workstations in three classrooms and seven laptops as a mobile
540 solution for all classrooms. These machines are all booting from the
541 terminal server. In the moment we are installing
30 laptops as mobile
542 workstations. Then the pupils have the possibility to work with these
543 machines in their classrooms. Internet access is realized by a WLAN
544 router, connected to the schools network. This is all done without a
545 dedicated system administrator or a computer science teacher.
</p
>
547 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
548 Edu?
</strong
></p
>
550 <p
>Teachers and pupils are Windows users.
&lt;Irony on
&gt; And Linux
551 isn
't cool. It
's software for freaks using the command line.
&lt;Irony
552 off
&gt; They don
't realize the stability of the system.
</p
>
554 <p
><strong
>Which free software do you use daily?
</strong
></p
>
556 <p
>Firefox, Thunderbird, LibreOffice, Ubuntu Server
12.04 (Samba,
557 Apache, MySQL, Joomla!, … and Skolelinux / Debian Edu)
</p
>
559 <p
><strong
>Which strategy do you believe is the right one to use to
560 get schools to use free software?
</strong
></p
>
562 <p
>In Germany we have the situation: every school is free to decide
563 which software they want to use. This decision is influenced by
564 teachers who learned to use Windows and MS Office. They buy a PC with
565 Windows preinstalled and an additional testing version of MS
566 Office. They don
't know about the possibility to use Free Software
567 instead. Another problem are the publisher of school books. They
568 develop their software, added to the school books, for Windows.

>The
<a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
578 project
</a
> provide an instruction manual for teachers, system
579 administrators and other users that contain useful tips for setting up
580 and maintaining a Debian Edu installation. This text is about how the
581 text processing of this manual is handled in the project.
</p
>
583 <p
>One goal of the project is to provide information in the native
584 language of its users, and for this we need to handle translations.
585 But we also want to make sure each language contain the same
586 information, so for this we need a good way to keep the translations
587 in sync. And we want it to be easy for our users to improve the
588 documentation, avoiding the need to learn special formats or tools to
589 contribute, and the obvious way to do this is to make it possible to
590 edit the documentation using a web browser. We also want it to be
591 easy for translators to keep the translation up to date, and give them
592 help in figuring out what need to be translated. Here is the list of
593 tools and the process we have found trying to reach all these
596 <p
>We maintain the authoritative source of our manual in the
597 <a href=
"https://wiki.debian.org/DebianEdu/Documentation/Wheezy/
">Debian
598 wiki
</a
>, as several wiki pages written in English. It consist of one
599 front page with references to the different chapters, several pages
600 for each chapter, and finally one
"collection page
" gluing all the
601 chapters together into one large web page (aka
602 <a href=
"https://wiki.debian.org/DebianEdu/Documentation/Wheezy/AllInOne
">the
603 AllInOne page
</a
>). The AllInOne page is the one used for further
604 processing and translations. Thanks to the fact that the
605 <a href=
"http://moinmo.in/
">MoinMoin
</a
> installation on
606 wiki.debian.org support exporting pages in
607 <a href=
"http://www.docbook.org/
">the Docbook format
</a
>, we can fetch
608 the list of pages to export using the raw version of the AllInOne
609 page, loop over each of them to generate a Docbook XML version of the
610 manual. This process also download images and transform image
611 references to use the locally downloaded images. The generated
612 Docbook XML files are slightly broken, so some post-processing is done
613 using the
<tt
>documentation/scripts/get_manual
</tt
> program, and the
614 result is a nice Docbook XML file (debian-edu-wheezy-manual.xml) and
615 a handfull of images. The XML file can now be used to generate PDF, HTML
616 and epub versions of the English manual. This is the basic step of
617 our process, making PDF (using dblatex), HTML (using xsltproc) and
618 epub (using dbtoepub) version from Docbook XML, and the resulting files
619 are placed in the debian-edu-doc-en binary package.
</p
>
621 <p
>But English documentation is not enough for us. We want translated
622 documentation too, and we want to make it easy for translators to
623 track the English original. For this we use the
624 <a href=
"http://packages.qa.debian.org/p/poxml.html
">poxml
</a
> package,
625 which allow us to transform the English Docbook XML file into a
626 translation file (a .pot file), usable with the normal gettext based
627 translation tools used by those translating free software. The pot
628 file is used to create and maintain translation files (several .po
629 files), which the translations update with the native language
630 translations of all titles, paragraphs and blocks of text in the
631 original. The next step is combining the original English Docbook XML
632 and the translation file (say debian-edu-wheezy-manual.nb.po), to
633 create a translated Docbook XML file (in this case
634 debian-edu-wheezy-manual.nb.xml). This translated (or partly
635 translated, if the translation is not complete) Docbook XML file can
636 then be used like the original to create a PDF, HTML and epub version
637 of the documentation.
</p
>
639 <p
>The translators use different tools to edit the .po files. We
641 <a href=
"http://www.kde.org/applications/development/lokalize/
">lokalize
</a
>,
642 while some use emacs and vi, others can use web based editors like
643 <a href=
"http://pootle.translatehouse.org/
">Poodle
</a
> or
644 <a href=
"https://www.transifex.com/
">Transifex
</a
>. All we care about
645 is where the .po file end up, in our git repository. Updated
646 translations can either be committed directly to git, or submitted as
647 <a href=
"https://bugs.debian.org/src:debian-edu-doc
">bug reports
648 against the debian-edu-doc package
</a
>.
</p
>
650 <p
>One challenge is images, which both might need to be translated (if
651 they show translated user applications), and are needed in different
652 formats when creating PDF and HTML versions (epub is a HTML version in
653 this regard). For this we transform the original PNG images to the
654 needed density and format during build, and have a way to provide
655 translated images by storing translated versions in
656 images/$LANGUAGECODE/. I am a bit unsure about the details here. The
657 package maintainers know more.
</p
>
659 <p
>If you wonder what the result look like, we provide
660 <a href=
"http://maintainer.skolelinux.org/debian-edu-doc/
">the content
661 of the documentation packages on the web
</a

684 keep gaining new users. Some weeks ago, a person showed up on IRC,
685 <a href=
"irc://irc.debian.org/#debian-edu
">#debian-edu
</a
>, with a
686 wish to contribute, and I managed to get a interview with this great
687 contributor Roger Marsal to learn more about his background.
</p
>
689 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
691 <p
>My name is Roger Marsal, I
'm
27 years old (
1986 generation) and I
692 live in Barcelona, Spain. I
've got a strong business background and I
693 work as a patrimony manager and as a real estate agent. Additionally,
694 I
've co-founded a British based tech company that is nowadays on the
695 last development phase of a new social networking concept.
</p
>
697 <p
>I
'm a Linux enthusiast that started its journey with Ubuntu four years
698 ago and have recently switched to Debian seeking rock solid stability
699 and as a necessary step to gain expertise.
</p
>
701 <p
>In a nutshell, I spend my days working and learning as much as I
702 can to face both my job, entrepreneur project and feed my Linux
705 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
706 project?
</strong
></p
>
708 <p
>I discovered the
<a href=
"http://www.ltsp.org/
">LTSP
</a
> advantages
709 with
"Ubuntu
12.04 alternate install
" and after a year of use I
710 started looking for an alternative. Even though I highly value and
711 respect the Ubuntu project, I thought it was necessary for me to
712 change to a more robust and stable alternative. As far as I was using
713 Debian on my personal laptop I thought it would be fine to install
714 Debian and configure an LTSP server myself. Surprised, I discovered
715 that the Debian project also supported a kind of Edubuntu equivalent,
716 and after having some pain I obtained a Debian Edu network up and
717 running. I just loved it.
</p
>
719 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
720 Edu?
</strong
></p
>
722 <p
>I found a main advantage in that, once you know
"the tips and
723 tricks
", a new installation just works out of the box. It
's the most
724 complete alternative I
've found to create an LTSP network. All the
725 other distributions seems to be made of plastic, Debian Edu seems to
726 be made of steel.
</p
>
728 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
729 Edu?
</strong
></p
>
731 <p
>I found two main disadvantages.
</p
>
733 <p
>I
'm not an expert but I
've got notions and I had to spent a considerable
734 amount of time trying to bring up a standard network topology. I
'm quite
735 stubborn and I just worked until I did but I
'm sure many people with few
736 resources (not big schools, but academies for example) would have switched
737 or dropped.
</p
>
739 <p
>It
's amazing how such a complex system like Debian Edu has achieved
740 this out-of-the-box state. Even though tweaking without breaking gets
741 more difficult, as more factors have to be considered. This can
742 discourage many people too.
</p
>
744 <p
><strong
>Which free software do you use daily?
</strong
></p
>
746 <p
>I use Debian, Firefox, Okular, Inkscape, LibreOffice and
747 Virtualbox.
</p
>
750 <p
><strong
>Which strategy do you believe is the right one to use to
751 get schools to use free software?
</strong
></p
>
753 <p
>I don
't think there is a need for a particular strategy. The free
754 attribute in both
"freedom
" and
"no price
" meanings is what will
755 really bring free software to schools. In my experience I can think of
756 the
<a href=
"http://www.r-project.org/
">"R
" statistical language
</a
>; a
757 few years a ago was an extremely nerd tool for university people.
758 Today it
's being increasingly used to teach statistics at many
759 different level of studies. I believe free and open software will
760 increasingly gain popularity, but I
'm sure schools will be one of the
761 first scenarios where this will happen.

>On larger sites, it is useful to use a dedicated storage server for
771 storing user home directories and data. The design for handling this
772 in
<a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a

773 to update the automount rules in LDAP and let the automount daemon on
774 the clients take care of the rest. I was reminded about the need to
775 document this better when one of the customers of
776 <a href=
"http://www.slxdrift.no/

</a
>, where I am
777 on the board of directors, asked about how to do this. The steps to
778 get this working are the following:
</p
>
782 <li
>Add new storage server in DNS. I use nas-server.intern as the
783 example host here.
</li
>
785 <li
>Add automoun LDAP information about this server in LDAP, to allow
786 all clients to automatically mount it on reqeust.
</li
>
788 <li
>Add the relevant entries in tjener.intern:/etc/fstab, because
789 tjener.intern do not use automount to avoid mounting loops.
</li
>
791 </ol

793 <p
>DNS entries are added in GOsa², and not described here. Follow the

810 netgroup membership or single IP addresses to have some limits on the
811 NFS access.
</p
>
813 <p
>The next step is to update LDAP. This can not be done using GOsa²,
814 because it lack a module for automount. Instead, use ldapvi and add

822 bottom of the document. The
"/

823 wild card matching everything the nas-server exports, removing the
824 need to list individual mount points in LDAP.

881 it until today. I also had been running the (kind of very advanced)
882 network of that school together with a team of very interested and
883 talented students in the age of
11 to
15 years, who took the chance to
884 learn a lot about open source and networking before I left the school
885 to help building another school

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

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

895 <p

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

898 <p
>I think that happened some time around
2009 when I first attended
899 <a href=
"http://www.froscon.org
">FrOSCon
</a
> and visited the project
900 booth. I think I wasn
't too interested back then because I used to
901 have an attitude of disliking software that does too much stuff on its
902 own. Maybe I was too inexperienced to realise the upsides of an
903 "out-of-the-box
" solution ;).
</p
>
905 <p
>The first time I actively talked to Skolelinux people was at
906 <a href=
"http://www.openrheinruhr.de
">OpenRheinRuhr
</a
> 2011 when the
907 BiscuIT project, a home-grewn software used by my school for various
908 really cool things from timetables and class contact lists to lunch
909 ordering, student ID card printing and project elections first got to
910 a stage where it could have been published. I asked the Skolelinux
911 guys running the booth if the project were interested in it and gave a
912 small demonstration, but there wasn
't any real feedback and the guys
913 seemed rather uninterested.
</p
>
915 <p
>After I left the school where I developed the software, it got
916 mostly lost, but I am now reimplementing it for my new school. I have
917 reusability and compatibility in mind, and I hop there will be a new
918 basis for contributing it to the Skolelinux project ;)!
</p
>
920 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
921 Edu?
</strong
></p
>
923 <p
>The most important advantage seems to be that it
"just
924 works
". After overcoming some minor (but still very annoying) glitches
925 in the installer, I got a fully functional, working school network,
926 without the month-long hassle I experienced when setting all that up
927 from scratch in earlier years. And above that, it rocked - I didn
't
928 have any real hardware at hand, because the school was just founded
929 and has no money whatsoever, so I installed a combined server (main
930 server, terminal services and workstation) in a VM on my personal
931 notebook, bridging the LTSP network interface to the ethernet port,
932 and then PXE-booted the Windows notebooks that were lying around from
933 it. I could use
8 clients without any performance issues, by using a
934 tiny little VM on a tiny little notebook. I think that
's enough to say
935 that it rocks!
</p
>
937 <p
>Secondly, there are marketing reasons. Life
's bad, and so no
938 politician will ever permit a setup described as
"Debian, an universal
939 operating system, with some really cool educational tools
" while they
940 will be jsut fine with
"Skolelinux, a single-purpose solution for your
941 school network
", even if both turn out to be the very same thing (yes,
942 this is unfair towards the Skolelinux project, and must not be taken
943 too seriously - you get the idea, anyway).
</p
>
945 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
946 Edu?
</strong
></p
>
948 <p
>I have not been involved with Skolelinux long enough to really
949 answer this question in a fair way. Thus, please allow me to put it in
950 other words:
"What do you expect from Skolelinux to keep liking it?
" I
951 can list a few points about that:
</p
>
955 <li
>always strive to get all things integrated into Debian upstream
956 <li
>be open to discussion about changes and the like, even with newcomers
957 <li
>be helpful at being helpful ;)
961 <p
>I
'm really sorry I cannot say much more about that :(!
</p
>
963 <p
><strong
>Which free software do you use daily?
</strong
></p
>
965 <p
>First of all, all software I use is free and open. I have abandoned
966 all non-free software (except for firmware on my darned phone) this
969 <p
>I run Debian GNU/Linux on all PC systems I use. On that, I mostly
970 run text tools. I use
971 <a href=
"https://www.mirbsd.org/mksh.htm
">mksh
</a
> as shell,
972 <a href=
"https://www.mirbsd.org/jupp.htm
">jupp
</a
> as very advanced
973 text editor (I even got the developer to help me write a script/macro
974 based full-featured student management software with the two),
975 <a href=
"http://mcabber.com/
">mcabber
</a
> for XMPP and
976 <a href=
"http://www.irssi.org/
">irssi
</a
> for IRC. For that overly
977 coloured world called the WWW, I use
978 <a href=
"https://www.mozilla.org/en-US/firefox/new/
">Iceweasel
979 (Firefox)
</a
>. Oh, and
<a href=
"http://www.mutt.org/
">mutt
</a
> for
982 <p
>However, while I am personally aware of the fact that text tools
983 are more efficient and powerful than anything else, I also use (or at
984 least operate) some tools that are suitable to bring open source to
985 kids. One of these things is
<a href=
"http://jappix.org/
">Jappix
</a
>,
986 which I already introduced to some kids even before they got aware of
987 Facebook, making them see for themselves that they do not need
988 Facebook now ;).
</p
>
990 <p
><strong
>Which strategy do you believe is the right one to use to
991 get schools to use free software?
</strong
></p
>
993 <p
>Well, that
's a two-sided thing. One side is what I believe, and one
994 side is what I have experienced.
</p
>
996 <p
>I believe that the right strategy is showing them the benefits. But
997 that won
't work out as long as the acceptance of free alternatives
998 grows globally. What I mean is that if all the kids are almost forced
999 to use Windows, Facebook, Skype, you name it at home, they will not
1000 see why they would want to use alternatives at school. I have seen
1001 students take seat in front of a fully-functional, modern Debian
1002 desktop that could do anything their Windows at home could do, and
1003 they jsut refused to use it because
"Linux sucks
". It is something
1004 that makes the council of our city spend around
600000 € to buy
1005 software - not including hardware, mind you - for operating school
1006 networks, and for installing a system that, as has been proved, does
1007 not work. For those of you readers who are good at maths, have you
1008 already found out how many lives could have been saved with that money
1009 if we had instead used it to bring education to parts of the world
1010 that need it? I have, and found it to be nothing less dramatic than
1011 plain criminal.
</p
>
1013 <p
>That said, the only feasible way appears to be the bottom up
1014 method. We have to bring free software to kids and parents. I have
1015 founded an association named
1016 <a href=
"https://www.teckids.org
">Teckids
</a
> here in Germany that does
1017 just that. We organise several events for kids and adolescents in the
1018 area of free and open source software, for example the
1019 <a href=
"http://kids.froscon.org
">FrogLabs
</a
>, which share staff with
1020 Teckids and are the youth programme of
1021 <a href=
"http://www.froscon.org
">the Free and Open Source Software
1022 Conference (FrOSCon)
</a
>. We do a lot more than most other conferences
1023 - this year, we first offered the FrogLabs as a holiday camp for kids
1024 aged
10 to
16. It was a huge success, with approx.
30 kids taking part
1025 and learning with and about free software through a whole weekend. All
1026 of us had a lot of fun, and the results were really exciting.
</p
>
1028 <p
>Apart from that, we are preparing a campaign that is supposed to bring
1029 the message of free alternatives to stuff kids use every day to them and
1030 their parents, e.g. the use of Jabber / Jappix instead of Facebook and
1031 Skype. To make that possible, we are planning to get together a team of
1032 clever kids who understand very well what their peers need and can bring
1033 it across to them. So we will have a peer-driven network of adolescents
1034 who teach each other and collect feedback from the community of minors.
1035 We then take that feedback and our own experience to work closely with
1036 open source projects, such as Skolelinux or Jappix, at improving their
1037 software in a way that makes it more and more attractive for the target
1038 group. At least I hope that we will have good cooperation with
1039 Skolelinux in the future ;)!
</p
>
1041 <p
>So in conclusion, what I believe is that, if it weren
't for the world
1042 being so bad, it should be very clear to the political decision makers
1043 that the only way to go nowadays is free software for various reasons,
1044 but I have learnt that the only way that seems to work is bottom up.
</p
>
1048 > * Who should be interviewed with this questions in the future?
1050 That
's probably the hardest question of them all, as I do not know the
1051 community. However, I would be willing to do the following:
1053 <li
>Run an interview with a German headteacher who is very open to
1054 free software, and also prefers it, but cannot really use it because
1055 of the decision makers above;
1056 <li
>Run interviews with some kids, both with and without previous
1057 knowledge about free software
1059 If that is wanted, just let me know ;).

1075 his success story with installing Debian Edu at their school. This

</p

1087 <p

1088 from teaching, I

1089 projects like the

1119 Edu?
</strong

1122 <li
>Skolelinux is - as we had to learn - not easily upgradable to
1123 the next version. Opposed to its genuine Debian base, upgrading to
1124 a new version means a full new installation from scratch to get it
1125 working again reliably.
1127 <li
>Skolelinux is based on Debian/stable, and therefore always a
1128 little outdated in terms of program versions compared to Edubuntu or
1129 similar educational Linux distros, which rather use Debian/testing
1132 <li
>Skolelinux has some very self-opinionated and stubborn default
1133 configuration which in my opinion adds unnecessary complexity and is
1134 not always suitable for a schools needs, the preset network
1135 configuration is actually a core definition feature of Skolelinux
1136 and not easy to change, so schools sometimes have to change their
1137 network configuration to make it
"Skolelinux-compatible
".
1139 <li
>Some proposed extensions, which were made available as
1140 contribution, like secure examination mode and lecture material
1141 distribution and collection, were not accepted into the mainline
1142 Skolelinux development and are now not easy to maintain in the
1143 future because of Skolelinux somewhat undeterministic update
1146 <li
>Skolelinux has only a very tiny number of base developers
1147 compared to Debian.
</li
>
1151 <p
>For these reasons and experience from our project, I would now
1152 rather consider using plain Debian for schools next time, until
1153 Skolelinux is more closely integrated into Debian and becomes
1154 upgradeable without reinstallation.

>About Debian Edu and Skolelinux
</p
>
1315 <p
>Debian Edu, also known as Skolelinux, is a Linux distribution based
1316 on Debian providing an out-of-the box environment of a completely
1317 configured school network. Immediately after installation a school
1318 server running all services needed for a school network is set up just
1319 waiting for users and machines being added via GOsa², a comfortable
1320 Web-UI. A netbooting environment is prepared using PXE, so after
1321 initial installation of the main server from CD or USB stick all other
1322 machines can be installed via the network. The provided school server
1323 provides LDAP database and Kerberos authentication service,
1324 centralized home directories, DHCP server, web proxy and many other
1325 services. The desktop contains more than
60 educational software
1326 packages and more are available from the Debian archive, and schools
1327 can choose between KDE, Gnome, LXDE and Xfce desktop environment.
</p
>
1329 <p
>This is the seventh test release based on Debian Wheezy. Basically
1330 this is an updated and slightly improved version compared to the
1331 Squeeze release.
</p
>
1333 <p
>Notes for upgrades from Alpha Prereleases
</p
>
1335 <p
>Alpha based installations should reinstall or downgrade the
1336 versions of gosa and libpam-mklocaluser to the ones used in this beta
1337 release. Both alpha and beta0 based installations should reinstall or
1338 deal with gosa.conf manually; there are two options: (
1) Keep
1339 gosa.conf and edit this file as outlined on the mailing list. (
2)
1340 Accept the new version of gosa.conf and replace both contained admin
1341 password placeholders with the password hashes found in the old one
1342 (backup copy!). In both cases all users need to change their password
1343 to make sure a password is set for CIFS access to their home
1344 directory.

1754 <description><p
>In the
<a href=
"http://www.skolelinux.org/
">Debian Edu /
1755 Skolelinux
</a
> project, we include a post-installation test suite,
1756 which check that services are running, working, and return the
1757 expected results. It runs automatically just after the first boot on
1758 test installations (using test ISOs), but not on production
1759 installations (using non-test ISOs). It test that the LDAP service is
1760 operating, Kerberos is responding, DNS is replying, file systems are
1761 online resizable, etc, etc. And it check that the PXE service is
1762 configured, which is the topic of this post.
</p
>
1764 <p
>The last week I
've fixed the DVD and USB stick ISOs for our Debian
1765 Edu Wheezy release. These ISOs are supposed to be able to install a
1766 complete system without any Internet connection, but for that to
1767 happen all the needed packages need to be on them. Thanks to our test
1768 suite, I discovered that we had forgotten to adjust our PXE setup to
1769 cope with the new names and paths used by the netboot d-i packages.
1770 When Internet connectivity was available, the installer fall back to
1771 using wget to fetch d-i boot images, but when offline it require
1772 working packages to get it working. And the packages changed name
1773 from debian-installer-
6.0-netboot-$arch to
1774 debian-installer-
7.0-netboot-$arch, we no longer pulled in the
1775 packages during installation. Without our test suite, I suspect we
1776 would never have discovered this before release. Now it is fixed
1777 right after we got the ISOs operational.
</p
>
1779 <p
>Another by-product of the test suite is that we can ask system
1780 administrators with problems getting Debian Edu to work, to run the
1781 test suite using
<tt
>/usr/sbin/debian-edu-test-install
</tt
> and see if
1782 any errors are detected. This usually pinpoint the subsystem causing
1783 the problem.

">our IRC channel
1803 #debian-edu
</a

1804 worked. We answered as good as we could, and even convinced him to
1805 help us with translations. And today I managed to get an interview
1806 with him, to learn more about him.

</strong
></p

1810 <p
>I
'm a
25 year old free software enthusiast, living in Romania,
1811 which is also my country of origin. Back in
2009, at a New Year
's Eve
1812 party, I had a very nice
<strike
>beer
</strike
> discussion with a
1813 friend, when we realized we have no organised Debian community in our
1814 country. A few days later, we put together the infrastructure for such
1815 community and even gathered a nice Debian-ish crowd. Since then, I
1816 began my quest as a free software hacker and activist and I am
1817 constantly trying to cover as much ground as possible on that
1820 <p
>A few years ago I founded a small web development company, which
1821 provided me the flexible schedule I needed so much for my
1822 activities. For the last
13 months, I have been the Technical Director
1823 of
<a href=
"http://ceata.org/
">Fundația Ceata
</a
>, which is a free
1824 software activist organisation endorsed by the FSF and the FSFE, and
1825 the only one we have in our country.
</p
>
1827 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
1828 project?
</strong
></p
>
1830 <p
>The idea of participating in the Debian Edu project was a surprise
1831 even to me, since I never used it before I began getting involved in
1832 it. This year I had a great opportunity to deliver a talk on
1833 educational software, and I knew immediately where to look. It was a
1834 love at first sight, since I was previously involved with some of the
1835 technologies the project incorporates, and I rapidly found a lot of
1836 ways to contribute.
</p
>
1838 <p
>My first contributions consisted in translating the installer and
1839 configuration dialogs, then I found some bugs to squash (I still
1840 haven
't fixed them yet though), and I even got my eyes on some other
1841 areas where I can prove myself helpful. Since the appetite for free
1842 software in my country is pretty low, I
'll be happy to be the first
1843 one around here advocating for the project
's adoption in educational
1844 environments, and maybe even get my hands dirty in creating a flavour
1845 for our own needs. I am not used to make very advanced plannings, so
1846 from now on, time will tell what I
'll be doing next, but I think I
1847 have a pretty consistent starting point.
</p

1849 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
1850 Edu?
</strong
></p
>
1852 <p
>Not a long time ago, I was in the position of configuring and
1853 maintaining a LDAP server on some Debian derivative, and I must say it
1854 took me a while. A long time ago, I was maintaining a bigger
1855 Samba-powered infrastructure, and I must say I spent quite a lot of
1856 time on it. I have similar stories about many of the services included
1857 with Skolelinux, and the main advantage I see about it is the
1858 out-of-the box availability of them, making it quite competitive when
1859 it comes to managing a school
's network, for example.
</p
>
1861 <p
>Of course, there is more to say about Skolelinux than the
1862 availability of the software included, its flexibility in various
1863 scenarios is something I can
't wait to experiment
"into the wild
" (I
1864 only played with virtual machines so far). And I am sure there is a
1865 lot more I haven
't discovered yet about it, being so new within the

><strong
>What do you see as the disadvantages of Skolelinux / Debian
1869 Edu?
</strong
></p
>
1871 <p
>As usual, when it comes to Debian Blends, I see as the biggest
1872 disadvantage the lack of a numerous team dedicated to the
1873 project. Every day I see the same names in the changelogs, and I have
1874 a constantly fear of the bus factor in this story. I
'd like to see
1875 Debian Edu advertised more as an entry point into the Debian
1876 ecosystem, especially amongst newcomers and students. IMHO there are a
1877 lot low-hanging fruits in terms of bug squashing, and enough
1878 opportunities to get the feeling of the Debian Project
's dynamics. Not
1879 to mention it
's a very fun blend to work on!
</p
>
1881 <p
>Derived from the previous statement, is the delay in catching up
1882 with the main Debian release and documentation. This is common though
1883 to all blends and derivatives, but it
's an issue we can all work
1886 <p
><strong
>Which free software do you use daily?
</strong
></p
>
1888 <p
>I can hardly imagine myself spending a day without Vim, since my
1889 daily routine covers writing code and hacking configuration files. I
1890 am a fan of the Awesome window manager (but I also like the
1891 Enlightenment project a lot!),
1892 <a href=
"http://www.claws-mail.org/
">Claws Mail

1893 use and very configurable behaviour. Recently I fell in love with
1894 <a href=
"https://launchpad.net/redshift

1895 get through the night without headaches. Of course, there is much more
1896 stuff in this bag, but I
'll need a blog on my own for doing this!

1901 <p
>Well, on this field, I cannot do much more than experiment right
1902 now. So, being far from having a recipe for success, I can only assume
1907 <li
>schools would like to get rid of proprietary software
</li
>
1909 <li
>students will love the openness of the system, and will want to
1910 experiment with it - maybe we need to harvest the native curiosity
1911 of teenagers more?
</li
>
1913 <li
>there is no
"right one
" when it comes to strategies, but it would
1914 be useful to have some success stories published somewhere, so
1915 other can get some inspiration from them (I know I
'd promote
1918 <li
>more active promotion - talks, conferences, even small school
1919 lectures can do magical things if they encounter at least one
1920 person interested. Who knows who that person might be? ;-)
</li
>
1924 <p
>I also see some problems in getting Skolelinux into schools; for
1925 example, in our country we have a great deal of corruption issues, so
1926 it might be hard(er) to fight against proprietary solutions. Also,
1927 people who relied on commercial software for all their lives, would be
1928 very hard to convert against their will.

<a href=

1946 <p

'm a South-African free software geek who lives in Cape Town. My
1947 days vary quite a bit since I
'm involved in too many things. As I
'm
1948 getting older I
'm learning how to focus a bit more :)
</p

1950 <p

'm also an Edubuntu contributor and I love when there are
1951 opportunities for the Edubuntu and Debian Edu projects to benefit from
1952 each other.
</p

1954 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
1955 project?
</strong
></p
>
1957 <p
>I
've been somewhat familiar with the project before, but I think my
1958 first direct exposure to the project was when I met Petter
1959 [Reinholdtsen] and Knut [Yrvin] at the Edubuntu summit in
2005 in
1960 London. They provided great feedback that helped the bootstrapping of
1961 Edubuntu. Back then Edubuntu (and even Ubuntu) was still very new and
1962 it was great getting input from people who have been around longer. I
1963 was also still very excitable and said yes to everything and to this
1964 day I have a big todo list backlog that I
'm catching up with. I think
1965 over the years the relationship between Edubuntu and Debian-Edu has
1966 been gradually improving, although I think there
's a lot that we could
1967 still improve on in terms of working together on packages. I
'm sure
1968 we
'll get there one day.
</p
>
1970 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
1971 Edu?
</strong
></p
>
1973 <p
>Debian itself already has so many advantages. I could go on about
1974 it for pages, but in essence I love that it
's a very honest project
1975 that puts its users first with no hidden agendas and also produces
1976 very high quality work.
</p
>
1978 <p
>I think the advantage of Debian Edu is that it makes many common
1979 set-up tasks simpler so that administrators can get up and running
1980 with a lot less effort and frustration. At the same time I think it
1981 helps to standardise installations in schools so that it
's easier for
1982 community members and commercial suppliers to support.
</p
>
1984 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
1985 Edu?
</strong
></p
>
1987 <p
>I had to re-type this one a few times because I
'm trying to
1988 separate
"disadvantages
" from
"areas that need improvement
" (which is
1989 what I originally rambled on about)
</p
>
1991 <p
>The biggest disadvantage I can think of is lack of manpower. The
1992 project could do so much more if there were more good contributors. I
1993 think some of the problems are external too. Free software and free
1994 content in education is a no-brainer but it takes some time to catch
1995 on. When you
've been working with the same proprietary eco-system for
1996 years and have gotten used to it, it can be hard to adjust to some
1997 concepts in the free software world. It would be nice if there were
1998 more Debian Edu consultants across the world. I
'd love to be one
1999 myself but I
'm already so over-committed that it
's just not possible
2000 currently.
</p
>
2002 <p
>I think the best short-term solution to that large-scale problem is
2003 for schools to be pro-active and share their experiences and grow
2004 their skills in-house. I
'm often saddened to see how much money
2005 educational institutions spend on
3rd party solutions that they don
't
2006 have access to after the service has ended and they could
've gotten so
2007 much more value otherwise by being more self-sustainable and
2008 autonomous.
</p
>
2010 <p
><strong
>Which free software do you use daily?
</strong
></p
>
2012 <p
>My main laptop dual-boots between Debian and Windows
7. I was
2013 Windows free for years but started dual-booting again last year for
2014 some games which help me focus and relax (Starcraft II in
2015 particular). Gaming support on Linux is improving in leaps and bounds
2016 so I suppose I
'll soon be able to regain that disk space :)
</p
>
2018 <p
>Besides that I rely on Icedove, Chromium, Terminator, Byobu, irssi,
2019 git, Tomboy, KVM, VLC and LibreOffice. Recently I
've been torn on
2020 which desktop environment I like and I
'm taking some refuge in Xfce
2021 while I figure that out. I like tools that keep things simple. I enjoy
2022 Python and shell scripting. I went to an Arduino workshop recently and
2023 it was awesome seeing how easy and simple the IDE software was to get
2024 up and running in Debian compared to the users running Windows and OS
2027 <p
>I also use mc which some people frown upon slightly. I got used to
2028 using Norton Commander in the early
90's and it stuck (I think the
2029 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
2033 get schools to use free software?
</strong
></p
>
2035 <p
>I think trying to force it is unproductive. I also think that in
2036 many cases it
's appropriate for schools to use non-free systems and I
2037 don
't think that there
's any particular moral or ethical problem with
2040 <p
>I do think though that free software can already solve so so many
2041 problems in educational institutions and it
's just a shame not taking
2042 advantage of that.
</p
>
2044 <p
>I also think that some curricula need serious review. For example,
2045 some areas of the world rely heavily on very specific versions of MS
2046 Office, teaching students to parrot menu items instead of learning the
2047 general concepts. I think that
's very unproductive because firstly, MS
2048 Office
's interface changes drastically every few years and on top of
2049 that it also locks in a generation to a product that might not be the
2050 best solution for them.
</p
>
2052 <p
>To answer your question, I believe that the right strategy is to
2053 educate and inform, giving someone the information they require to
2054 make a decision that would work for them.

">Debian Edu, also known as
2075 Skolelinux
</a
>, is a Linux distribution based on Debian providing an
2076 out-of-the box environment of a completely configured school
2077 network. Immediately after installation a school server running all
2078 services needed for a school network is set up just waiting for users
2079 and machines being added via GOsa², a comfortable Web-UI. A netbooting
2080 environment is prepared using PXE, so after initial installation of
2081 the main server from CD, DVD or USB stick all other machines can be
2082 installed via the network. The provided school server provides LDAP
2083 database and Kerberos authentication service, centralized home
2084 directories, DHCP server, web proxy and many other services. The

2184 We have two problems blocking the release of the Wheezy version we
2185 hope to get released soon. The two problems require some with PHP
2186 skills, and we seem to lack anyone with both time and PHP skills in

2194 This used to work, but stopped working some time since Squeeze.

>It has been a while since my last English

">Debian Edu and Skolelinux
</a
>
2218 interview last November. But the developers and translators are still
2219 pulling along to get the Wheezy based release out the door, and this
2220 time I managed to get an interview from one of the French translators
2221 in the project, Cédric Boutillier.
</p
>
2223 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
2225 <p
>I am
34 year old. I live near Paris, France. I am an assistant
2226 professor in probability theory. I spend my daytime teaching
2227 mathematics at the university and doing fundamental research in
2228 probability in connexion with combinatorics and statistical physics.
</p
>
2230 <p
>I have been involved in the Debian project for a couple of years
2231 and became Debian Developer a few months ago. I am working on Ruby
2232 packaging, publicity and translation.
</p
>
2234 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
2235 project?
</strong
></p
>
2237 <p
>I came to the Debian Edu project after a call for translation of
2238 <a href=
"http://wiki.debian.org/DebianEdu/Documentation/Manuals
">the
2239 Debian Edu manual
</a
> for the release of Debian Edu Squeeze. Since
2240 then, I have been working on updating the French translation of the
2243 <p
>I had the opportunity to make an installation of Debian Edu in a
2244 virtual machine when I was preparing localised version of some screen
2245 shots for the manual. I was amazed to see it worked out of the box and
2246 how comprehensive the list of software installed by default was.
</p
>
2248 <p
>What amazed me was the complete network infrastructure directly
2249 ready to use, which can and the nice administration interface provided
2250 by
<a href=
"https://oss.gonicus.de/labs/gosa/
">GOsa²
</a
>. What pleased
2251 me also was the fact that among the software installed by default,
2252 there were many
"traditional
" educative software to learn languages,
2253 to count, to program... but also software to develop creativity and
2254 artistic skills with music (
<a href=
"http://ardour.org/
">Ardour
</a
>,
2255 <a href=
"http://audacity.sourceforge.net/
">Audacity
</a
>) and
2256 movies/animation (I was especially thinking of
2257 <a href=
"http://linuxstopmotion.sourceforge.net/
">Stopmotion
</a
>).
</p
>
2259 <p
>I am following the development of Debian Edu and am hanging out on
2260 <a href=
"irc://irc.debian.org/%
23debian-edu
">#debian-edu
</a
>.
2261 Unfortunately, I don
't much time to get more involved in this
2262 beautiful project.
</p
>
2264 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
2265 Edu?
</strong
></p
>
2267 <p
>For me, the main advantages of Skolelinux/Debian Edu are its
2268 community of experts and its precise documentation, as well as the
2269 fact that it provides a solution ready to use.
</p
>
2271 <p
>I would add also the fact that it is based on the rock solid Debian
2272 distribution, which ensures stability and provides a huge collection
2273 of educational free software.
</p
>
2275 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
2276 Edu?
</strong
></p
>
2278 <p
>Maybe the lack of manpower to do lobbying on the
2279 project. Sometimes, people who need to take decisions concerning IT do
2280 not have all the elements to evaluate properly free software
2281 solutions. The fact that support by a company may be difficult to find
2282 is probably a problem if the school does not have IT personnel.
</p
>
2284 <p
>One can find support from a company by looking at
2285 <a href=
"http://wiki.debian.org/DebianEdu/Help/ProfessionalHelp
">the
2286 wiki dokumentation
</a
>, where some countries already have a number of
2287 companies providing support for Debian Edu, like Germany or
2288 Norway. This list is easy to find readily from the manual. However,
2289 for other countries, like France, the list is empty. I guess that
2290 consultants proposing support for Debian would be able to provide some
2291 support for Debian Edu as well.
</p
>
2293 <p
><strong
>Which free software do you use daily?
</strong
></p
>
2295 <p
>I am using the KDE Plasma Desktop. But the pieces of software I use
2296 most runs in a terminal: Mutt and OfflineIMAP for emails, latex for
2297 scientific documents, mpd for music. VIM is my editor of choice. I am
2298 also using the mathematical software
2299 <a href=
"http://www.scilab.org/en/scilab/about
">Scilab
</a
> and
2300 <a href=
"http://www.sagemath.org/index.html
">Sage
</a
> (built from
2301 source as not completely packaged for Debian, yet).
2303 <p
><strong
>Do you have any suggestions for teachers interested in
2304 using the free software in Debian to teach mathematics and
2305 statistics?
</strong
></p
>
2307 <p
>I do not have any
"nice
" recommendations for statistics. At our
2308 university, we use both
<a href=
"http://www.r-project.org/
">R
</a
> and
2309 Scilab to teach statistics and probabilistic simulations. For
2310 geometry, there are nice programs:
</p
>
2314 <li
><a href=
"http://www.drgeo.eu/
">drgeo
</a
> and
2315 <a href=
"http://edu.kde.org/applications/all/kig
">kig
</a
> to do
2316 constructions in planar geometry
2318 <li
><a href=
"http://www.geom.uiuc.edu/software/download/kali.html
">kali
</a
>
2319 to discover symmetry groups (the so-called wallpapers and frieze
2320 groups), although the interface looks a bit old.
</li
>
2324 <p
>I like also
2325 <a href=
"http://edu.kde.org/applications/all/cantor
">cantor
</a
>, which
2326 provides a uniform interface to SciLab, Sage,
2327 <a href=

">Octave
</a
>, etc...
</p
>
2329 <p
><strong
>Which strategy do you believe is the right one to use to
2330 get schools to use free software?
</strong
></p
>
2332 <p
>My suggestions would be to
</p
>
2336 <li
>advertise the reduction of costs when free software is used.
</li
>
2338 <li
>communicate about the quality of free software projects, using
2339 well known examples like Firefox, ThunderBird and
2340 OpenOffice.org/LibreOffice.
</li
>
2342 <li
>advertise the living and strong community around the project.
</li
>
2344 <li
>show that it is not more difficult to use than any other

2507 dataingeniør studiet ved Høgskolen i Sør Trøndelag. Interessen for
2508 data har siden ung alder vært tilstede og jeg har i tillegg alltid
2509 vært glad i å lære nye ting. Med teknologi som endres svært hurtig er
2510 det alltid noe nytt å lære. Noe som igjen har gjort det svært
2511 interessant å følge med på utviklingen. Jeg valgte dataingeniør
2512 studiet grunnet ønske om å lære enda mer om programmering og utvikling
2513 av store systemer.

>Hvordan kom du i kontakt med Skolelinux-prosjektet?

2517 <p
>Skolelinux prosjektet hørte jeg først om i media. Men det var først
2518 når jeg skulle velge bacheloroppgave at jeg fattet mer interesse for
2519 prosjektet. Et enkelt søk på nettet førte meg til skolelinux sine
2520 hjemmesider. Informasjonen jeg fant der gjorde meg enda nysgjerrig og
2521 jeg valgte derfor en oppgave som gikk ut på å få en
2522 <a href=
"http://www.raspberrypi.org
">Raspberry PI
</a
>. Altså en
2523 ultra-billig datamaskin til å kjøre Debian Edu på lik linje med
2524 vanlige datamaskiner. I løpet av prosjektet ble det gjort mye
2525 forskning på nettet. Det var mye jeg måtte forstå rundt hvordan
2526 operativsystemet Linux fungerte før jeg kunne angripe
2527 problemet. Prøvde først å finne ut hvordan man kunne transformere en
2528 vanlig installasjon av Skolelinux til Raspberry PI, men dette var
2529 altfor vanskelig å jeg endte opp med mer spørsmål enn svar. Det ble
2530 videre opprettet kontakt med Skolelinux utviklere på IRC der jeg fikk
2531 diskutert hvilken retning jeg burde gå for å få til en fullverdig
2532 løsning. Det ble bestemt at jeg skulle gå for å først installere
2533 <a href=
"http://www.raspbian.org/
">Raspian
</a
>. Dette er et
2534 operativsystem basert på Debian spesiallaget for Raspberry Pi sin
2535 maskinvare. Nå som Debian var installert på datamaskinen gjenstod det
2536 å installere de nødvendige Skolelinux pakkene for å få til et
2537 fullverdig system. Disse pakkene ble installert manuelt i første
2538 omgang, men ble senere installert automatisk via et script som Petter
2539 Reinholdtsen laget. Dette scriptet er så enkel å bruke at man er i
2540 gang med installasjonen i løpet av bare
5 minutter. Ikke nok med det,
2541 alt skjer helt automatisk. Alt i alt er jeg veldig fornøyd med
2542 resultatet av installasjonsprosessen. Raspberry Pi er en veldig svak
2543 maskin og det merkes godt når man har installert Skolelinux på
2544 den. Video og
3D-rendering fungerer utrolig dårlig, men nettsurfing og
2545 kontorprogrammer fungerer godt. Det kan derfor konkluderes med at
2546 datamaskinen er egnet for enkle oppgaver.
2548 <p
>Jeg syns det er viktig påpeke at dette kun er startfasen av en slik
2549 løsning. På markedet finnes det nå maskiner som har bedre hardware enn
2550 Raspberry Pi. Det er store muligheter for at man kan klare å
2551 installere Skolelinux på disse også, og da forsvinner nok mest
2552 sannsynlig ytelsesproblemene med Video og
3D rendering også.
</p
>
2554 <p
>Det ble også prøvd med en løsning som gjorde at Raspberry Pi
2555 fungerte som en tynnklient. Denne løsningen hadde langt bedre ytelse
2556 med tanke på hastighet og brukeropplevelse. Men også her var video og
2557 3D rendering dårlig. Det ble brukt en liten Linux distribusjon kalt
2558 <a href=

>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
2563 <p
>Fordelen med Skolelinux er mange. At det er gratis er en stor
2564 fordel, men at det er så mange som er med på å utvikle det og
2565 vedlikeholde det er en enda større fordel. Allerede før jeg startet
2566 med prosjektet så jeg mange fordeler, og når jeg nærmet meg sluttfasen
2567 så jeg langt flere. At prosjektet skulle inneha en så høy kvalitet
2568 hadde jeg aldri trodd. En vanlig Skolelinux installasjon har de
2569 nødvendige programmene og funksjonen som både små og store skoler i
2570 tillegg til organisasjoner kan klare seg med. At prosjektet tilbyr en
2571 så komplett løsning er en kjempefordel. Installasjonen er knirkefri
2572 og det er svært enkelt å installere og komme i gang.
</p

2574 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
2576 <p
>Ulempene jeg ser med prosjektet er ryddigheten av websidene. Selv
2577 om websidene er enkle og konsise er det allikevel ikke appellerende i
2578 like stor grad som for eksempel
2579 <a href=
"http://www.ubuntu.com
">Ubuntu
</a
> sine sider. Deres side
2580 tilbyr, i tillegg til godt design og presentasjon, en nettbasert
2581 emulator av deres operativsystem. Dette er en stor fordel slik jeg ser
2582 det. Bortsett fra dette ser jeg absolutt ingen ulemper med
2583 Skolelinux-prosjektet.

<a href=
"http://xbmc.org/
">XBMC
</a
>. Det enorme
2589 samfunnet rundt dette prosjektet har gjort dette til et program som
2590 dekker alles behov. Man kan tilpasse det akkurat slik man vil både med
2591 tanke på utseende og funksjoner ved installere plug-ins eller
2594 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
2595 skoler til å ta i bruk fri programvare?
</strong
></p
>
2597 <p
>Strategien som burde brukes sett fra mine øyne er
2598 markedsføring. Jeg er sikker på at om flere skoler fikk et lite innsyn
2599 i hvor bra Skolelinux er så ville de ikke nølt med å gå over fra noe
2600 annet som koster de store summer. At skolelinux til de grader tilbyr
2601 en så komplett løsning bure komme frem. Enten via reklamekampanjer
2602 eller ved å sende ut folk til skoler for så å la skolenettverk
2603 ansvarlige få teste ut hvordan Skolelinux fungerer i praksis. Om det
2604 i tillegg ble utviklet gode websider og en emulator for å la brukere
2605 prøve operativsystemet ville nok dette ha styrket inntrykket
2606 betraktelig.

2863 services needed for a school network is set up just waiting for users
2864 and machines being added via GOsa², a comfortable Web-UI. A netbooting
2865 environment is prepared using PXE, so after initial installation of
2866 the main server from CD, DVD or USB stick all other machines can be
2867 installed via the network.

2993 the video show a walk-through of of the menu content, demonstration of
2994 a few programs and his view of our distribution.
</p

2996 <p
>There is also some really nice quotes (transcribed by me, might
2997 have heard wrong). While looking thought the Graphics menu:
</p
>
3000 "Basically everything you ever need in a school environment.
"
3003 <p
>And as a general evaluation of the entire distribution:
</p
>
3006 "So, yeah, a bit bloated. It kept all the Debian stuff in there, just
3007 to keep it nice and GNU. So, I do not want to go on about it, but
3008 lets give it
7 out of
10. I am not going to use it. That is because
3009 I am not deploying a school network. There may be some mythical
3010 feature to help you deploy Skolelinux on a school network.
"
3013 <p
>To bad he did not test the server profile, and discovered the PXE
3014 installation option. It make it possible to install only the main
3015 server from CD, and the rest of the machines via the net, and might be
3016 considered the mythical feature he talk about. :)
</p
>
3018 <p
>While looking through the menus, there is also this funny comment
3019 about the part of the K menu generated from the Debian menu subsystem:
3022 "[The K menu] have a special Debian section for software that no-one
3023 is going to look at, because it contain lots of junky stuff that you
3024 actually don
't need in the education distribution, but have just been
3025 included because it isn
't stripped out for some reason.
"
3028 <p
>I guess it is yet another argument for merging the Debian menu and
3029 Gnome/KDE desktop menu entries into
3030 <a href=

">one
3031 consistent menu system

>Etter en lang pause og travle uker har jeg endelig klart å få
3144 samlet et nytt intervju med en av folkene i
3145 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet.
3146 Denne gang er det Helge Tore Høyland, en mangeårig bidragsyter på
3147 epostlistene og ellers i prosjektet.
</p
>
3149 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
3151 <p
>Eg er IT-konsulent/teknikker hjå eit firma i Steinkjer med navn
3152 <a href=
"http://unoit.no/
">Uno IT
</a
>. Uno IT er eit lite firma som
3153 drifter nettverk og maskiner for små og mellomstore firma
3154 Steinkjer-området. Per dags dato er me
2 ansatte. Min faglege bakgrunn
3155 er Fagbrev som it-teknikker, samt nokre fag innen nettverk- og
3156 server-drift frå HiST og NTNU. Dagleg arbeid består i oppsett av nye
3157 maskiner og hjelp til sluttbrukere, samt oppsett og vedlikehold av eit
3158 vidt spekter av fagsystemer ute hjå kunder. Erfaring med Skolelinux
3159 har eg hatt i forbindelse med drifting av
3160 <a href=
"http://www.bjorkly.no/
">Bjørkly skule
</a
>, ein privat
3161 grunnskule i Namsos-området. I dag har skulen
65 elever,
15 lærere,
1
3162 hovedserver og ca
60 klienter som kjører halvtjukt. Eg har bygd og
3163 driftet systemet sidan summaren
2006.
</p
>
3165 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
3167 <p
>Eg kom i kontakt med Skolelinux-prosjektet via ein artikkel i eit
3168 fagblad, som eg ikkje lenger hugsar namnet på. I og med at eg allereie
3169 hadde pusla med nettverk for ein annan skule, fatta eg straks
3170 interesse for prosjektet.
</p
>
3172 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
3174 <p
>Fordelane med Skolelinux er sentralisert administrasjon og svært
3175 mange gode verktøy «ut av boksen». Veldig kjekt å kunne drifte
60
3176 klientar med berre å «bry» seg med ein server. Levetid for systemets
3177 hardware er og ein veldig fin effekt. I tillegg kjem fordelar som økt
3178 sikkerhet og mindre lisenskostnader. Etter min erfaring er det og
3179 mykje mindre driftskostnader med eit slikt system enn konkurrerande
3180 system, pga enkelhet med sentralisert administrasjon. På grunn av at
3181 Skolelinux er basert på Debian er det òg svært stabilt.
</p
>
3183 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
3185 <p
>Ulemper er mangel på vilje til å følge standarer ute i markedet,
3186 som fører til mangel på støtte til nokre mykje brukte ting. Flash og
3187 Java er typiske eksempel. Sidan Debian satsar på stabilitet framfor å
3188 ha nyeste pakke av eit program, kan ein i nokre tilfeller kome borti
3189 at program vert «for gamle». Det er spesielt nettlesaren som er
3190 utsett. Mangel på vilje til å utvikle pedagogisk programvare, i Noreg,
3191 for «alle» platformer fører òg til noko hovudbry.
</p
>
3193 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
3195 <p
>Til dagleg bruker eg svært mange forskjellige «fri programvare»
3196 program. Firefox, Thunderbird, Freecommander, ImgBurn, Clonezilla,
3197 OCS inventory, Icinga, Skolelinux, SystemRescueCD og mykje meir.
</p
>
3199 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
3200 skoler til å ta i bruk fri programvare?
</strong
></p
>
3202 <p
>Strategisk må ein fokusere på at sluttbruker eigentleg ikkje er så
3203 fokusert på at det er fri programvare men at det skal «berre fungere».
3204 Gjer det enkelt å bruker og ikkje minst å administrere. For Skolelinux
3205 sin del må ein få eit betre fokus på overganger. Utbytting av servere
3206 må gå meir automatisk, import og eksport av brukerbase og maskinbase
3207 med meir må kunne gå enkelt og oppgradering til neste versjon må bli
3208 mykje meir automatisk og gjennomtesta. Ein må unngå at ein må sette
3209 opp frå start når ein byter ut ein server eller oppgraderer til neste
3210 versjon. For å få Skolelinux til å bli eit betre alternativ for skular
3211 må ein ha fokus på nettlesaren. Denne må bli «up to date» og støtte
3212 dei protokollar og tillegg som vert brukt av forlag med meir. Etter
3213 kvart som meir og meir blir flytta ut i «skya» vert dette viktigare og
3214 viktigare. Ein kunne ynskje og jobbe for at forlag med fleire tar i
3215 bruk opne standarer, men inntil det skjer, må systemet kunne brukast
3216 mot desse fagsystema.
</p
>
3218 <p
>For meg har prosjektet med Skolelinux vore ein svært artig og
3219 lærerik prosess. Miljøet rundt er ikkje enormt stort, dog stort nok,
3220 men det er svært hjelpevillig og engasjert.

3231 project also this year received a Christmas present from Another
3232 Agency in Trondheim. NOK
1000,- showed up on our donation account
3233 December
24th. I want to express our thanks for this very welcome
3234 present. As the Debian Edu / Skolelinux project is very short on
3235 funding these days, and thus lack the money to do regular developer
3236 gatherings, this donation was most welcome. One developer gathering
3237 cost around NOK
15&nbsp;
000,-, so we need quite a lot more to keep the
3238 development pace we want. Thus, I hope their example this year is
3239 followed by many others. :)

3257 interesting, as I am involved with several organizations where
3258 accounting is an issue, and I have not really become too friendly with
3259 the different web based systems we use. I find it hard to find what I
3260 look for in the menus and even harder try to get sensible data out of
3261 the systems. Ledger seem different. The accounting data is kept in
3262 text files that can be stored in a version control system, and there
3264 are at least

3320 welcome to Angela Fuß. :)

3322 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
3324 <p
>I am a
39-year-old woman living in the very north of Germany near
3325 Denmark. I live in a patchwork family with
"my man
" Mike Gabriel, my
3326 two daughters, Mikes daughter and Mikes and my rather newborn son.
3328 <p
>At the moment - because of our little baby - I am spending most of
3329 the day by being a caring and organising mom for all the kids.
3330 Besides that I am really involved into and occupied with several inner
3331 growth processes: New born souls always bring the whole familiar
3332 system into movement and that needs time and focus ;-). We are also
3333 in the middle of buying a house and moving to it.
</p
>
3335 <p
>In
2013 I will work again in my job in a German foundation for
3336 nature conservation. I am doing public relation work there. Besides
3337 that - and that is the connection to Skolelinux / Debian Edu - I am
3338 working in our own school project
"IT-Zukunft Schule
" in North
3339 Germany. I am responsible for the quality assurance, the customer
3340 relationship management and the communication processes in the
3343 <p
>Since
2001 I constantly have been training myself in communication
3344 and leadership. Besides that I am a forester, a landscaping gardener
3345 and a yoga teacher.
</p
>
3347 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
3348 project?
</strong
></p
>
3350 <p
>I fell in love with Mike ;-).
</p
>
3352 <p
>Very soon after getting to know him I was completely enrolled into
3353 Free Software. At this time Mike did IT-services for one newly
3354 founded school in Kiel. Other schools in Kiel needed concepts for
3355 their IT environment. Often when Mike came home from working at the
3356 newly founded school I found myself listening to his complaints about
3357 several points where the communication with the schools head or the
3358 teachers did not work. So we were clear that he would not work for
3359 one more school if we did not set up a structure for communication
3360 between him, the schools head, the teachers, the students and the
3363 <p
>Together with our friend and hardware supplier Andreas Buchholz we
3364 started to get an overview of free software solutions suitable for
3365 schools. One day before Christmas
2010 Mike and I had a date with Kurt
3366 Gramlich in Gütersloh. As Kurt and I are really interested in building
3367 networks of people and in being in communication we dived into
3368 Skolelinux and brought it to the first grammar schools in Northern

><strong
>What do you see as the advantages of Skolelinux / Debian
3376 Edu?
</strong
></p
>
3378 <p
>First I have to say: I cannot answer this question technically. My
3379 answer comes rather from a social point of view.
</p
>
3381 <p
>The biggest advantage of Skolelinux / Debian Edu I see is the large
3382 and strong international community of Debian Developers in the
3383 background which is very alive and connected over mailinglists, blogs
3384 and meetings. My constant feeling for the Debian Community is: If
3385 something does not work they will somehow fix it. All is well
3386 ;-). This is of course a user experience. What I also get as a big
3387 advantage of Skolelinux / Debian Edu is that everybody who uses it and
3388 works with it can also contribute to it - that includes students,
3389 teachers, parents...
</p
>
3391 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
3392 Edu?
</strong
></p
>
3394 <p
>I will answer this question relating to the internal structure of
3395 Skolelinux / Debian Edu.
</p
>
3397 <p
>What I see as a major disadvantage is that there is a gap between
3398 the group of developers for Debian Edu and the people who make the
3399 marketing, that means the people that bring Skolelinux to the
3400 schools. There is a lack of communication between these two groups and
3401 I think that does not really work for Skolelinux / Debian Edu.
</p
>
3403 <p
>Further I appreciate that Skolelinux / Debian Edu is known as a
3404 do-ocracy. Nevertheless I keep asking myself if at some points a
3405 democracy or some kind of hierarchical project structure would be good
3406 and helpful. I am also missing some kind of contact between the
3407 Skolelinux / Debian Edu communities in Europe or on an international
3408 level. I think it would be good if there was more sharing between the
3409 different countries using Skolelinux / Debian Edu.

3411 <p
><strong
>Which free software do you use daily?
</strong
></p
>
3413 <p
>On my laptop I am still using an Ubuntu
10.04 with a Gnome Desktop
3414 on. As applications I use Openoffice.org, Gedit, Firefox, Pidgin,
3415 LaTeX and GnuCash. For mails I am using Horde. And I am really fond of
3416 my N900 running with Maemo.
</p
>
3418 <p
><strong
>Which strategy do you believe is the right one to use to
3419 get schools to use free software?
</strong
></p
>
3421 <p
>I am really convinced that in our school project
"IT-Zukunft
3422 Schule
" we have developed (and keep developing) a great way to get
3423 schools to use Free Software. We have written a detailed concept for
3424 that so I cannot explain the whole thing here. But in a nutshell the
3425 strategy has three crucial pillars:
</p
>
3429 <li
>We really take time to get what sort of stories, questions and
3430 concerns the schools head and the teachers have about using different
3431 kinds of IT and we take time to enrol them into Free Software.
</li
>
3433 <li
>Our solution for schools is never just technical. In the centre
3434 are always the people who are going to use the software. From the very
3435 beginning of the planning for a school, we tell the schools head that
3436 they are paying us not only for a technical solution for their school,
3437 they also pay us for leading all the communication processes
3438 needed. If they do not want that, we are not working with them because
3439 we cannot give a guarantee for the quality of our work then.
</li
>
3441 <li
>Another focus lies in the training of teachers and students in
3442 co-administrating the IT-System at their school. They start getting in
3443 contact with the Skolelinux / Debian Edu community and they get the
3444 offer to become more and more independent from us.

</p

3467 <p
>I sommer (
2012-
07-
23) hadde Fremover et oppslag om at Narvik
3468 kommune hadde spart mellom
10 og
20 millioner kroner de siste årene på
3469 å bruke Skolelinux på sine skoler. Harstad har også tatt i bruk
3470 Skolelinux på alle sine skoler. Som tidligere Ballangsværing gledet
3471 det meg stort å se at skoleløsningen vi har utviklet siden
2001 tas i
3472 bruk i området der jeg vokste opp, og dermed bidrar til en bedre og
3473 billigere skolehverdag.
</p
>
3475 <p
>Skolelinux er en komplett IT-løsning for elevnettverket på en
3476 skole, med både nettverkstjenester og løsning for elevmaskiner med
3477 pedagogisk programvare, som tillater en å øke levetiden på en
3478 datamaskin i skolen med mange år. En undersøkelse publisert i mars
3479 2012 viste at de
56 norske skolene som har offentliggjort at de bruker
3480 Skolelinux eller annen Linuxutgave hadde
36% større PC-tetthet enn
3481 landsgjennomsnittet, når en ser på tall rapportert til Grunnskolens
3482 Informasjonssystem. I følge Paul Reidar Løsnesløkken, IKT-konsulent i
3483 Nord-Odal, fungerer datamaskiner godt til de er
8 til
10 år gamle.
</p
>
3485 <p
>I høst (
2012-
09-
29) fortalte Fremover hvordan Ballangen kommune har
3486 opparbeidet seg
20 millioner i underskudd og nok havner på Robek-lista
3487 fra nyttår. Kanskje Ballangen også burde ta i bruk Skolelinux for å
3488 spare penger? Hvis kommunen mangler kompetanse lokalt på Linux finnes
3489 det kommersielle selskaper som tilbyr driftstjenester rundt
3490 Skolelinux, og jeg bør vel avsløre at jeg selv er involvert i et av
3491 dem, Skolelinux Drift AS. Kommunen kan dermed få hjelp hvis de ikke
3492 ønsker å bygge opp egen kompetanse.

>After a long break in my row of interviews with people in the
3660 <a href=
"http://www.skolelinux.org/
">Debian Edu and Skolelinux
</a
>
3661 community, I finally found time to wrap up another. This time it is
3662 Giorgio Pioda, which showed up on the mailing list at the start of
3663 this year, asking questions and inspiring us to improve the first time
3664 administrators experience with Skolelinux. :) The interview was
3665 conduced in May, but I only found time to publish it now.
</p

3667 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p

3669 <p
>I have a PhD in chemistry but since several years I work as teacher
3670 in secondary (
15-
18 year old students) and tertiary (a kind of
"light
"
3671 university) schools. Five years ago I started to manage a Learning
3672 Management Service server and slowly I got more and more involved with
3673 IT.
3 years ago the graduating schools moved completely to Linux and I
3674 got the head of the IT for this. The experience collected in chemistry
3675 labs computers (for example NMR analysis of protein folding) and in
3676 the IT-courses during university where sufficient to start. Self
3677 training is anyway very important
</p
>
3679 <p
>I live in the Italian speaking part of Switzerland, and the
3680 <a href=
"http://www.spse.ch/
">SPSE school
</a
> (secondary) is a very
3681 special sport school for young people who try to became sport pro (for
3682 all sports, we have dozens of disciplines represented) and we are
3683 recognised by the Olympic Swiss Organisation.
3685 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
3686 project?
</strong
></p
>
3688 <p
>Looking for Linux / Primary Domain Controller (PDC) I found it
3689 already several years ago. But since the system was still not
3690 Kerberized and since our schools relies strongly on laptops I didn
't
3691 use it. I plan to introduce it in the next future, probably for the
3692 next school year, since the squeeze release solved this security
3695 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
3696 Edu?
</strong
></p
>
3698 <p
>Many. First of all there is a strong and living community that is
3699 very generous for help and hints. Chat help is crucial, together with
3700 the mailing list. Second. With Skolelinux you get an already well
3701 engineered platform and you don
't have to start to build up your PDC
3702 and your clients from GNU/scratch; I
've already done this once and I
3703 can tell it, it is hard. Third, since Skolelinux is a standard
3704 platform, it is way easier to educate other IT people and even if the
3705 head IT is sick another one could pick up the task without too much
3708 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
3709 Edu?
</strong
></p
>
3711 <p
>The only real problem I see is that it is a little too less
3712 flexible at client level. Debian stable is rocky and desirable, but
3713 there are many reasons that force for another choice. For example the
3714 need of new drivers for new PC, or the need for a specific OS for some
3715 devices that have specific software packages for another specific
3716 distribution (I have such a case for whiteboards that have only
3717 Ubuntu packages). Thus, I prepared compatibility packages educlient
3718 and eduroaming, hoping not to use them ;-)
</p
>
3720 <p
><strong
>Which free software do you use daily?
</strong
></p
>
3722 <p
>I have a Debian Stable PDC at school (Kerberos, NIS, NFS) with
3723 mixed Debian and Ubuntu clients. If you think that this triad
3724 combination is exotic... well I discovered right yesterday that
3725 <a href=
"http://moo.nac.uci.edu/~hjm/Perceus-Report.html
">Perceus
</a
>
3726 has the same...
</p
>
3728 <p
>For myself I run Debian wheezy/sid, but this combination is good
3729 only I you have enough competence to fix stuff for yourself, if
3730 something breaks. Daily I use texmacs, gnumeric, a little bit of R
3731 statistics, kmplot, and less frequently OpenOffice.org.
</p
>
3733 <p
><strong
>Which strategy do you believe is the right one to use to
3734 get schools to use free software?
</strong
></p
>
3736 <P
>I think that the only real argument that school managers
"hear
" is
3737 cost reduction. They don
't give too much weight on quality, stability,
3738 just because they are normally not open to change.
</p
>
3740 <p
>Students adapts very quickly to GNU/Linux (and for them being able
3741 to switch between different OS is a plus value); teachers and managers
3742 don
't.
</p
>
3744 <p
>We decided to move to Linux because students at our school have own
3745 laptop and we have the responsibility to keep the laptop ready to use;
3746 we were really unsatisfied with Microsoft since every Monday we had
20
3747 machine to fix for viral infections... With Linux this has been
3748 reduced to zero, since people installs almost only from official
3749 repositories. I think that our special needs brought us to Linux.
3750 Those who don
't have such needs will hardly move to Linux.

3767 <p
>Artikkelen med tittelen
"Narvik kommune bruker gratisprogram i
3768 skolen - Har spart millioner
", forteller om hvordan bruken av
3769 Skolelinux er en stor suksess i Narvik siden det ble tatt i bruk i
3770 2004. Her er noen fine sitater:
</p
>
3773 "- Skolelinux har spart kommunen for store pengesummer, millionbeløp,
3774 som de heller kan bruke på andre ting, sier IKT-konsulent Viggo
3778 <p
>Avisen forteller at de har fått tilgang til beregninger som viser
3779 at Narvik kommune har spart noe mellom
10 og
20 millioner kroner de
3780 siste
8 årene på å bruke Skolelinux, og fortsetter:
</p
>
3784 "Regnestykket tar høyde for sparte kostnader til lisenser som medfølger
3785 de alternative operativsystemene, lavere driftskostnader og lengre
3786 levetid på datautstyret. Totalt har Narvikskolen en maskinpark på
3787 1600 maskiner fordelt på de
11 skolene fra Skjomen i sør til Bjerkvik
3792 <p
>Viggo Fedreheim sier dette om hvor noe av gevinsten kommer fra:
</p
>
3795 "- Vi kan gjenbruke gamle maskiner i skolen som er for dårlig andre
3796 steder i kommunen der de ikke bruker Skolelinux. Levetiden på en
3797 datamaskin blir
3-
5 år lenger med Skolelinux. Vi kaller det for
3798 grønn IT, miljøvennlig IT.
"
3801 <p
>Her er det mulighet for flere kommuner å få et godt IT-system på
3802 skolene, hvis de er villige til å forsøke. De som ikke har kompetanse

'm a
44 year old country guy that have been working
12 years at
3879 the same school as
50% IT-manager and
50% Teacher. My educational
3880 background is fil.kand in history and religious beliefs, an exam as a
3881 "folkhighschool

3882 Norwegian I believe it
's called
"Vuxenupplaring

3883 in
"Technology and social change

'm not really a tech guy, I
3884 just like to study how humans and technology interact and that is my
3885 perspective when working with IT.
</p
>
3887 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
3888 project?
</strong
></p
>
3890 I have followed the Skolelinux project for quite some time by
3891 now. Earlier I tested out the K12-LTSP project, which we used for some
3892 time, but I really like the idea of having a distribution aimed to be
3893 a complete solution for schools with necessary tools integrated. When
3894 K12-LTSP abandoned that idea some years ago, I started to look more
3895 seriously into Skolelinux instead.
3897 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
3898 Edu?
</strong
></p
>
3900 The big point of Skolelinux to me is that it is a complete
3901 distribution, ready to install. It has LDAP-support, MS Windows
3902 integration tools and so forth already configured, saving an
3903 administrator a lot of time and headache. We were using another Linux
3904 based thin-client system called Thinlinc, that has served us very
3905 well. But that Skolelinux is based on VNC and LTSP, to me, is better
3906 when it comes to the kind of multimedia used in schools. That is
3907 showing videos from Youtube or educational TV. It is also easier to
3908 mix thin clients with workstations, since the user settings will be the
3909 same. In our VNC-based solution you had to
"beat around the bush
" by
3910 setting up a second, hidden, home-directory for user settings for the
3911 workstations, because they will be different from the ones used on the
3912 thin clients. Skolelinux support for diskless workstations are very
3913 convenient since a school today often need to use a class room
3914 projector showing videos in full screen. That is easily done with a
3915 small integrated media computer running as a diskless workstation. You
3916 have only two installs to update and configure. One for the thin
3917 clients and one for the workstations. Also saving a lot of time. Our
3918 old system was also based on Redhat and CentOS. They are both very
3919 nice distributions, but they are sometimes painfully slow when it
3920 comes to updating multimedia support and multimedia programs (even
3921 such as Gimp), leaving us with a bit
"oldish
" applications. Debian is
3924 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
3925 Edu?
</strong
></p
>
3927 <p
>Debian is a bit too quick when it comes to updating. As an example
3928 we use old HP terminals as thinclients, and two times already this
3929 year (
2012) the updates you get from the repositories has stopped
3930 sound from working with them. It
's a kernel/ALSA issue. So you have
3931 to be more careful properly testing the updates before you run them in
3932 a production environment. This has never happened with CentOS.
</p
>
3934 <p
>I also would like to be able to set my own domain-settings at
3935 install time. In Skolelinux they are kind of hard coded into the
3936 distribution, when it comes to LDAP and at least samba integration.
3937 That is more a cosmetic/translation issue, and not a real problem.
3938 Running MS Windows applications within the Skolelinux environment needs
3939 to be better supported. That is, running them seamlessly via RDP, and
3940 support for single-sign on. That will make the transition to free
3941 software easier, because you can keep the applications you really
3942 need. No support will make it impossible if you work in a school where
3943 some applications can
't be open source. As for us we really need to
3944 run Adobe InDesign in our journalist classes. We run a journalist
3945 education, and is one of the very few non university ones that is ok:d
3946 by Svenska journalistförbundet (Swedish journalist association). Our
3947 education gives the pupils the right of membership there, once they
3948 are done. This is important if you want to get a job.
</p
>
3950 <p
>Adobe InDesign is the program most commonly used in newspapers and
3951 magazines. We used Quark Express before, but they seem to loose there
3952 market to Adobe. The only
"equivalent
" to InDesign in the opensource
3953 world is Scribus, and its not advanced enough. At least not according
3954 to the teacher. I think it would be possible to use it, because they
3955 are not supposed to learn a program, they are supposed to learn how to
3956 edit and compile a newspaper. But politically at our school we are not
3957 there yet. And Scribus lacks a lot of things you find i InDesign.
</p
>
3959 <p
>We used even a windows program for sound editing when it comes to
3960 the radio-journalist part. The year to come we are going to try
3961 Audacity. That software has the same kind of limitations compared to
3962 Adobe Audition, but that teacher is a bit more open minded. We have
3963 tried Ardour also, but that instead is more like a music studio
3964 program, not intended for the kind of editing taking place in a radio
3965 studio. Its way to complex and the GUI is to scattered when you only
3966 want to cut, make pass-overs, add extra channels and normalise. Those
3967 things you can do in Audacity, but its not as easy as in Audition. You
3968 have to do more things manually with envelopes, and that is a bit old
3969 fashion and timewasting. Its also harder to cut and move sound from
3970 one channel to another, which is a thing that you do frequently
3971 because you often find yourself needing to rearrange parts of the
3972 sound file.
</p
>
3974 <p
>So, I am not sure we will succeed in replacing even Audition, but we
3975 will try. The problem is the students have certain expectations when
3976 they start an education towards a profession. So the programs has to
3977 look and feel professional. Good thing with radio, there are many
3978 programs out there, that radio studios use, so its not as standardised
3979 as Newspaper editing. That means, it does not really matter what
3980 program they learn, because once they start working they still have to
3981 learn the program the studio uses, so instead focus has to be to learn
3982 the editing part without to much focus on a specific software.

3984 <p
><strong
>Which free software do you use daily?
</strong

3986 <p
>Myself I
'm running Linux Mint, or Ubuntu these days. I use almost
3987 only open source software, and preferably Linux based. When it comes
3988 to most used applications its OpenOffice, and Firefox (of course ;)
3991 <p
><strong
>Which strategy do you believe is the right one to use to
3992 get schools to use free software?
</strong
></p
>
3994 <p
>To get schools to use free software there has to be good open
3995 source software that are windows based, to ease the transition. But
3996 it
's also very important that the multimedia support is working
3997 flawlessly. The problems with Youtube, Twitter, Facebook and whatever
3998 will create problems when it comes to both teachers and
3999 students. Economy are also important for schools, so using thin
4000 clients, as long as they have good multimedia support, is a very good
4001 idea. It
's also important that the open source software works even for
4002 the administration. It
's hard to convince the teachers to stick with
4003 open source, if the principal has to run Windows. It also creates a
4004 problem if some classes has to use Windows for there tasks, since that
4005 will create a difference in
"status
" between classes, so a good
4006 support for running windows applications via the thin client (Linux)
4007 desktop is essential. At least at our school, where we have mixed
4008 level of educations, from high-school to journalist-school.

>In the Debian Edu / Skolelinux project, we have realised that one
4028 of the major blockers for the project success is the purchasing skills
4029 in schools and municipalities. We provide what the happy users of
4030 Debian Edu / Skolelinux say they need and to a lower cost than the
4031 alternatives, and yet so few schools decide to use our solution. I
4032 was pleased to discover the same observation done by mySociety and Tom

4038 <p
>Of course there are other factors involved as well, like our
4039 projects bad marketing skills and the Linux community fragmentation
4040 causing worry with the people on the outside, so we as a project need
4041 to keep working hard to gain users, but it is a up-hill battle when

4245 fag på siden. Har jobbet som lærer der jeg var driftsansvarlig på
4246 Ulsrud VGS i Oslo. Senere eide og jobbet jeg flere år i Linuxlabs AS,
4247 som jeg solgte til Redpill Linpro AS (den gangen Linpro AS). I dag
4248 jobber jeg med ulike investeringer, hovedsaklig i eiendom, men også i

4253 <p
>Fruen og jeg dro på en lengre seiltur i
2000, der jeg måtte ha
"noe
4254 å gjøre
" under hjemturen over Atlanteren. Jeg kjøpte et par bøker om
4255 Linux i en bokhandel i New York og ble veldig fascinert. Etter
4256 hjemkomsten begynte jeg å jobbe på Ulsrud VGS, som naturfagslærer, men
4257 som IT-interessert ble jeg fort en del av den nye IT-satsningen som
4258 skulle løfte Ulsrud og gi skolen en bedre rykte. Vi hadde ganske
4259 mange maskiner, som gikk på Win98 og to servere som ble oppgradert til
4260 Win2000. Systemene var ustabil og dårlige. På leting etter noe
4261 bedre, uten å knekke ryggen økonomisk, kom jeg over
"Linux i Skolen
"
4262 og Skolelinux. Jeg tok kontakt med miljøet og en gjeng møtte opp på
4263 skolen, der vi gjorde en liten testinstallasjon. Etter et par år var
4264 ryggraden på skolen Linux (Skolelinux) og vi hadde flere hundre
4265 maskiner, både tynne klienter (gamle og nye), bærbare (Debian) og noen
4266 stasjonære (Win2000). På et tidspunkt var Ulsrud den råeste IT-skolen
4267 og det irriterte skolesjefen i Oslo, da de satset hardt på

</strong

4272 <p
>Det som gjorde at vi fikk inn Skolelinux var ene og alene
4273 økonomiske. Det faktum at vi slapp å kjøpe masse nye lisenser og at
4274 vi kunne bruke gammel hardware. Alt i alt gjorde dette at vi sparte
4275 mye, men i stede for å bruke mindre på IT brukte vi det vi sparte på å
4276 skaffe mer hardware og på den måten gi det beste tilbudet i landet til
4277 våre elever. For oss som driftet var det himmel å ha et system som
4278 gikk å administrere sentralt og effektivt. Det var heller ikke så
4279 dumt at vi kunne
"låse
" maskinene mer effektivt enn vi kunne med
4280 Microsoft Windows, slik at vi slapp mye feil og problemer som ble
4281 forårsaket av
"kreative
" elever.

4285 <p
>Det vi slet med var mangelen av en del programmer lærerne ville ha.
4286 Husker ikke alle, men det var et knippe med pedagogiske programmer de
4287 ikke fikk. I dag tror jeg det problemet er langt mindre da det meste
4288 av disse kjøres gjennom nettleseren.

4294 Firefox brukes mest av disse. På Apple-serveren hjemme bruker jeg
4295 HandBrake mye, og jeg har installert OpenWRT på flere av
4296 basestasjonene både hjemme og på jobben. I tillegg til det har jeg i
4297 flere år finansiert et prosjekt som heter
4298 <a href=

4299 vi lager et rammeverk for søk, der alt vi bruker fri programvare. Det

4303 skoler til å ta i bruk fri programvare?

4305 <p
>Når det gjelder IT og skole er fortsatt økonomi veldig viktig. Så
4306 man må oppfylle minimumskravene (ikke være best, men bra nok) og selge
4307 seg inn på hvor mye man sparer. Det betyr selvsagt at man sparer på
4308 lisenser, men også på driftsinnsats. Men nå når jeg ikke er en aktiv
4309 del av miljøet lenger hører jeg nesten ingen ting om fri programvare.
4310 Jeg stiller meg da spørsmålet om det har blitt stille rundt miljøet,
4311 eller om jeg kun så det tydeligere før når jeg var aktiv? Uansett er
4312 det for stille rundt Skolelinux-prosjektet nå.

4324 This time we get to know José Luis Redrejo Rodríguez, one of our great
4325 helpers from Spain. His effort was the reason we added support for
4326 several desktop types (KDE, Gnome and most recently LXDE) in Debian
4327 Edu, and have all of these available in the recently published

><strong
>How did you get in contact with the Skolelinux/Debian Edu
4338 project?
</strong
></p
>
4340 <p
>At
2006, I verified that both, we in Extremadura and Skolelinux
4341 project, had been working in parallel for some years, doing very
4342 similar things, using very similar tools and with similar targets, so
4343 I decided it was time to join forces as much as possible.
</p
>
4345 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4346 Edu?
</strong
></p
>
4348 <p
>A community of highly skilled experts working together, with a
4349 really open schema of collaboration and work. I really love the
4350 concepts of Do-ocracy and Merit-ocracy and the way these concepts are
4351 been used everyday inside Debian Edu.
</p
>
4353 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
4354 Edu?
</strong
></p
>
4356 <p
>Sometimes the differences in the implementations, laws or
4357 economical and technical resources in the different countries don
't
4358 allow us to agree in the same solution for all of us, and several
4359 approaches are needed, what is a waste of effort. Also, there is a
4360 lack of more man power to be able to follow the fast evolution of the
4361 technologies in school.
</p
>
4363 <p
><strong
>Which free software do you use daily?
</strong
></p

4365 <p
>Debian, of course, and due to my kind of job I am most of my time
4366 between Iceweasel,
<a href=

</a

</p
>
4369 <p
><strong
>Which strategy do you believe is the right one to use to
4370 get schools to use free software?
</strong
></p
>
4372 <p
>I think there is not a single strategy because there are very
4373 different scenarios: schools with mixed proprietary and free
4374 environments, schools using only workstations, other schools using
4375 laptops, netbooks, tablets, interactive white-boards, etc.
</p
>
4377 <p
>Also the range of ages of the students is very broad and you can
4378 not use the same solutions for primary schools and secondary or even
4379 universities. So different strategies are needed.
</p
>
4381 <p
>But, looking at these differences, and looking back to the things
4382 we
've done and implemented, and the places were we have spent most of
4383 our forces, I think we should focus as much as possible in free
4384 multi-platform environments, using only standards tools, and moving
4385 more and more to Internet or network solutions that could be deployed
4386 using wireless. I think we
'll see more and more personal devices in
4387 the schools, devices the students and teachers will take home with
4388 them, so the solutions must be able to be taken at home and continue
4389 working there.

4408 changed from using tasksel tasks to using meta packages (aka packages
4409 with dependencies like our education-* packages), and our installation
4410 system depend on tasksel tasks in
4411 /usr/share/tasksel/debian-edu-tasks.desc for package
4412 installation.
</li
>
4414 <li
>Enable Kerberos login for more services. Now with the Kerberos
4415 foundation in place, we should use it to get single sign on with more
4416 services, and avoiding unneeded password / login questions. We should
4417 at least try to enable it for these services:
4420 <li
>CUPS for admins to add/configure printers and users when using
4422 <li
>Nagios for admins checking the system status.
</li
>
4423 <li
>GOsa for admins updating LDAP and users changing their passwords.
</li
>
4424 <li
>LDAP for admins updating LDAP.
</li
>
4425 <li
>Squid for users when exam mode / filtering is active.
</li
>
4426 <li
>ssh for admins and users to save a password prompt.
</li
>
4428 </ul
></li
>
4430 <li
>When we move GOsa to use Kerberos instead of LDAP bind to
4431 authenticate users, we should try to block or at least limit access to
4432 use LDAP bind for authentication, to ensure Kerberos is used when it
4433 is intended, and nothing fall back to using the less safe LDAP bind
</li
>
4435 <li
>Merge debian-edu-config and debian-edu-install. The split made
4436 sense when d-e-install did a lot more, but these days it is just an
4437 inconvenience when we update the debconf preseeding values.
</li
>
4439 <li
>Fix partman-auto to allow us to abort the installation before
4440 touching the disk if the disk is too small. This is
4441 <a href=
"http://bugs.debian.org/
653305">BTS report #
653305</a
> and the
4442 d-i developers are fine with the patch and someone just need to apply
4443 it and upload. After this is done we need to adjust
4444 debian-edu-install to use this new hook.
</li
>
4446 <li
>Adjust to new LTSP framework (boot time config instead of install
4447 time config). LTSP changed its design, and our hooks to install
4448 packages and update the configuration is most likely not going to work
4451 <li
>Consider switching to NBD instead of NFS for LTSP root, to allow
4452 the Kernel to cache files in its normal file cache, possibly speeding
4453 up KDE login on slow networks.
</li
>
4455 <li
>Make it possible to create expired user passwords that need to
4456 change on first login. This is useful when handing out password on
4457 paper, to make sure only the user know the password. This require
4458 fixes to the PAM handling of kdm and gdm.
</li
>
4460 <li
>Make GUI for adding new machines automatically from sitesummary.
4461 The current command line script is not very friendly to people most
4462 familiar with GUIs. This should probably be integrated into GOsa to
4463 have it available where the admin will be looking for it..
</li
>
4465 <li
>We should find way for Nagios to check that the DHCP service
4466 actually is working (as in handling out IP addresses). None of the
4467 Nagios checks I have found so far have been working for me.
</li
>
4469 <li
>We should switch from libpam-nss-ldapd to sssd for all profiles
4470 using LDAP, and not only on for roaming workstations, to have less
4471 packages to configure and consistent setup across all profiles.
</li
>
4473 <li
>We should configure Kerberos to update LDAP and Samba password
4474 when changing password using the Kerberos protocol. The hook was
4475 requested in
<a href=
"http://bugs.debian.org/
588968">BTS report
4476 #
588968</a
> and is now available in Wheezy. We might need to write a
4477 MIT Kerberos plugin in C to get this.
</li
>
4479 <li
>We should clean up the set of applications installed by default.
4482 <li
>reduce the number of chemistry visualisers
</li
>
4483 <li
>consider dropping xpaint
</li
>
4484 <li
>and probably more?
</li
>
4485 </ul
></li
>
4487 <li
>Some hardware need external firmware to work properly. This is
4488 mostly the case for WiFi network cards, but there are some other
4489 examples too. For popular laptops to work out of the box, such
4490 firmware need to be installed from non-free, and we should provide
4491 some GUI to do this. Ubuntu already have this implemented, and we
4492 could consider using their packages. At the moment we have some
4493 command line script to do this (one for the running system, another
4494 for the LTSP chroot).
</li
>
4497 <li
>In Squeeze, we provide KDE, Gnome and LXDE as desktop options. We
4498 should extend the list to Xfce and Sugar, and preferably find a way to
4499 install several and allow the admin or the user to select which one to
4502 <li
>The golearn tool from the goplay package make it easy to check out
4503 interesting educational packages. We should work on the package
4504 tagging in Debian to ensure it represent all the useful educational
4505 packages, and extend the tool to allow it to use packagekit to install
4506 new applications with a simple mouse click.
</li
>
4508 <li
>The Squeeze version got half a exam solution already in place,
4509 with the introduction of iptable based network blocking, but for it to
4510 be a complete exam solution the Squid proxy need to enable
4511 filtering/blocking as well when the exam mode is enabled. We should
4512 implement a way to easily enable this for the schools that want it,
4513 instead of the
"it is documented
" method of today.
</li
>
4515 <li
>A feature used in several schools is the ability for a teacher to
4516 "take over
" the desktop of individual or all computers in the room.
4517 There are at least three implementations,
4518 <a href=

4519 <a href=

">controlaula
</a

4520 <a href=

</a

4521 them and make it trivial to set it up in a school. The challenges is
4522 how to distribute crypto keys and how to group computers in one room
4523 and how to set up which machine/user can control the machines in a
4524 given room.
</li
>
4526 <li
>Tablets and surf boards are getting more and more popular, and we
4527 should look into providing a good solution for integrating these into
4528 the Debian Edu network. Not quite sure how. Perhaps we should
4529 provide a installation profile with better touch screen support for
4530 them, or add some sync services to allow them to exchange
4531 configuration and data with the central server. This should be
4532 investigated.

2010, Mike Gabriel showed up on the
4547 <a href=
"http://www.skolelinux.org/

</a

4548 mailing list. He quickly proved to be a valuable developer, and
4549 thanks to his tireless effort we now have Kerberos integrated into the

</p
>
4553 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
4555 <p
>My name is Mike Gabriel, I am
38 years old and live near Kiel,
4556 Schleswig-Holstein, Germany. I live together with a wonderful partner
4557 (Angela Fuß) and two own children and two bonus children (contributed
4558 by Angela).
</p
>
4560 <p
>During the day I am part-time employed as a system administrator
4561 and part-time working as an IT consultant. The consultancy work
4562 touches free software topics wherever and whenever possible. During
4563 the nights I am a free software developer. In the gaps I also train in
4564 becoming an osteopath.
</p
>
4566 <p
>Starting in
2010 we (Andreas Buchholz, Angela Fuß, Mike Gabriel)
4567 have set up a free software project in the area of Kiel that aims at
4568 introducing free software into schools. The project
's name is
4569 "IT-Zukunft Schule
" (IT future for schools). The project links IT
4570 skills with communication skills.
</p
>
4572 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4573 project?
</strong
></p
>
4575 <p
>While preparing our own customised Linux distribution for
4576 "IT-Zukunft Schule
" we were repeatedly asked if we really wanted to
4577 reinvent the wheel. What schools really need is already available,
4578 people said. From this impulse we started evaluating other Linux
4579 distributions that target being used for school networks.
</p
>
4581 <p
>At the end we short-listed two approaches and compared them: a
4582 commercial Linux distribution developed by a company in Bremen,
4583 Germany, and Skolelinux / Debian Edu. Between
12/
2010 and
03/
2011 we
4584 went to several events and met people being responsible for marketing
4585 and development of either of the distributions. Skolelinux / Debian
4586 Edu was by far much more convincing compared to the other product that
4587 got short-listed beforehand--across the full spectrum. What was most
4588 attractive for me personally: the perspective of collaboration within
4589 the developmental branch of the Debian Edu project itself.
</p
>
4591 <p
>In parallel with this, we talked to many local and not-so-local
4592 people. People teaching at schools, headmasters, politicians, data
4593 protection experts, other IT professionals.
</p
>
4595 <p
>We came to two conclusions:
</p
>
4597 <p
>First, a technical conclusion: What schools need is available in
4598 bits and pieces here and there, and none of the solutions really fit
4599 by
100%. Any school we have seen has a very individual IT setup
4600 whereas most of each school
's requirements could mapped by a standard
4601 IT solution. The requirement to this IT solution is flexibility and
4602 customisability, so that individual adaptations here and there are
4603 possible. In terms of re-distributing and rolling out such a
4604 standardised IT system for schools (a system that is still to some
4605 degree customisable) there is still a lot of work to do here
4606 locally. Debian Edu / Skolelinux has been our choice as the starting
4609 <p
>Second, a holistic conclusion: What schools need does not exist at
4610 all (or we missed it so far). There are several technical solutions
4611 for handling IT at schools that tend to make a good impression. What
4612 has been missing completely here in Germany, though, is the enrolment
4613 of people into using IT and teaching with IT.
"IT-Zukunft Schule
"
4614 tries to provide an approach for this.
</p
>
4616 <p
>Only some schools have some sort of a media concept which explains,
4617 defines and gives guidance on how to use IT in class. Most schools in
4618 Northern Germany do not have an IT service provider, the school
's IT
4619 equipment is managed by one or (if the school is lucky) two (admin)
4620 teachers, most of the workload these admin teachers get done in there
4621 spare time.
</p
>
4623 <p
>We were surprised that only a very few admin teachers were
4624 networked with colleagues from other schools. Basically, every school
4625 here around has its individual approach of providing IT equipment to
4626 teachers and students and the exchange of ideas has been quasi
4627 non-existent until
2010/
2011.
</p
>
4629 <p
>Quite some (non-admin) teachers try to avoid using IT technology in
4630 class as a learning medium completely. Several reasons for this
4631 avoidance do exist.
</p
>
4633 <p
>We discovered that no-one has ever taken a closer look at this
4634 social part of IT management in schools, so far. On our quest journey
4635 for a technical IT solution for schools, we discussed this issue with
4636 several teachers, headmasters, politicians, other IT professionals and
4637 they all confirmed: a holistic approach of considering IT management
4638 at schools, an approach that includes the people in place, will be new
4639 and probably a gain for all.
</p
>
4641 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4642 Edu?
</strong
></p
>
4644 <p
>There is a list of advantages: international context, openness to
4645 any kind of contributions, do-ocracy policy, the closeness to Debian,
4646 the different installation scenarios possible (from stand-alone
4647 workstation to complex multi-server sites), the transparency within
4648 project communication, honest communication within the group of
4649 developers, etc.

4651 <p

4652 Edu?
</strong

4654 <p
>Every coin has two sides:
</p
>
4656 <p
>Technically:
<a href=
"http://bugs.debian.org/
311188">BTS issue
4657 #
311188</a
>, tricky upgradability of a Debian Edu main server, network
4658 client installations on top of a plain vanilla Debian installation
4659 should become possible sometime in the near future, one could think
4660 about splitting the very complex package debian-edu-config into
4661 several portions (to make it easier for new developers to
4662 contribute).
</p
>
4664 <p
>Another issue I see is that we (as Debian Edu developers) should
4665 find out more about the network of people who do the marketing for
4666 Debian Edu / Skolelinux. There is a very active group in Germany
4667 promoting Skolelinux on the bigger Linux Days within Germany. Are
4668 there other groups like that in other countries? How can we bring
4669 these marketing people together (marketing group A with group B and
4670 all of them with the group of Debian Edu developers)? During the last
4671 meeting of the German Skolelinux group, I got the impression of people
4672 there being rather disconnected from the development department of
4673 Debian Edu / Skolelinux.
</p

4675 <p
><strong
>Which free software do you use daily?
</strong
></p
>
4677 <p
>For my daily business, I do not use commercial software at all.
</p
>
4679 <p
>For normal stuff I use Iceweasel/Firefox, Libreoffice.org. For
4680 serious text writing I prefer LaTeX. I use gimp, inkscape, scribus for
4681 more artistic tasks. I run virtual machines in KVM and Virtualbox.
</p
>
4683 <p
>I am one of the upstream developers of X2Go. In
2010 I started the
4684 development of a Python based X2Go Client, called PyHoca-GUI.
4685 PyHoca-GUI has brought forth a Python X2Go Client API that currently
4686 is being integrated in Ubuntu
's software center.
</p
>
4688 <p
>For communications I have my own Kolab server running using Horde
4689 as web-based groupware client. For IRC I love to use irssi, for Jabber
4690 I have several clients that I use, mostly pidgin, though. I am also
4691 the Debian maintainer of Coccinella, a Jabber-based interactive
4692 whiteboard.

4694 <p
>My favourite terminal emulator is KDE
's Yakuake.

4720 <p

4721 Mathematics, and Computer Science (
"Informatik

12
4722 years (since
2000), I have been working for a comprehensive (and soon,
4723 also inclusive) school leading to all kind of general levels, such as
4724 O- or A-level (

4731 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4732 project?
</strong
></p
>
4734 <p
>We had tried different Linux based school servers, when members of
4735 my local Linux User Group (LUG OWL) detected Skolelinux. I remember
4736 very well, being part of a party celebrating the Linux New Media Award
4737 (
"Best Newcomer Distribution
", also nominated: Ubuntu) that was given
4738 to Skolelinux at Linux World Exposition in Frankfurt,
2005 (IIRC). Few
4739 months later, I had the chance to join a developer meeting in Ulsrud
4740 (Oslo) and to hand out the award to Knut Yrvin and others. For more
4741 than
7 years, Skolelinux is part of our schools infrastructure, namely
4742 our main server (tjener), one LTSP (today without thin clients), and
4743 approximately
50 work stations. Most of these have the option to boot a
4744 locally installed Skolelinux image. As a consequence, I joined quite
4745 a few events dealing with free software or Linux, and met many Debian
4746 (Edu) developers. All of them seemed quite nice and competent to me,
4747 one more reason to stick to Skolelinux.

4750 Edu?
</strong
></p
>
4752 <p
>Debian driven, you are given all the advantages of a community
4753 project including well maintained updates. Once, you are familiar with
4754 the network layout, you can easily roll out an entire educational
4755 computer infrastructure, from just one installation media. As only
4756 free software (FOSS) is used, that supports even elderly hardware,
4757 up-sizing your IT equipment is only limited by space (i.e. available
4758 labs). Especially if you run a LTSP thin client server, your
4759 administration costs tend towards zero.
</p
>
4761 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
4762 Edu?
</strong
></p
>
4764 <p
>While Debian
's stability has loads of advantages for servers, this
4765 might be different in some cases for clients: Schools with unlimited
4766 budget might buy new hardware with components that are not yet
4767 supported by Debian stable, or wish to use more recent versions of
4768 office packages or desktop environments. These schools have the
4769 option to run Debian testing or other distributions - if they have the
4770 capacity to do so. Another issue is that Debian release cycles
4771 include a wide range of changes; therefor a high percentage of human
4772 power seems to be absorbed by just keeping the features of Skolelinux
4773 within the new setting of the version to come. During this process,
4774 the cogs of Debian Edu are getting more and more professional,
4775 i.e. harder to understand for novices.

</strong

4788 <li
>Support computer science as regular subject in schools to make
4789 people really
"own
" their hardware, to make them understand the
4790 difference between proprietary software products, and free software
4791 developing.
</li
>
4793 <li
>Make budget baskets corresponding: In Germany
's public schools
4794 there are more or less fixed budgets for IT equipment (including
4795 licenses), so schools won
't benefit from any savings here. This
4796 privilege is left to private schools which have consequently a large
4797 share among German Skolelinux schools.
</li
>
4799 <li
>Get free software in the seminars where would-be teachers are
4800 trained. In many cases, teachers
' software customs are respected by
4801 decision makers rather than the expertise of any IT experts.
</li
>
4803 <li
>Don
't limit ourself to free software run natively. Everybody uses
4804 free software or free licenses (for instance Wikipedia), and this
4805 general concept should get expanded to free educational content to be
4806 shared world wide (school books e.g.).
</li
>
4808 <li
>Make clear where ever you can that the market share of free (libre)
4809 office suites is much above
20 p.c. today, and that you pupils don
't
4810 need to know the
"ribbon menu
" in order to get employed.

4814 <li
>Spread free software, or even collections of portable free apps

4836 gledelig overrasket da han dukket opp i Skolelinux-prosjektet etter å
4837 ikke ha sett noe til ham på mange år.

4841 <p
>Jeg er utdannet kokk av yrke, og har utøvet yrket i
12 år. Men
4842 etter at ryggen sa takk før seg, studerte jeg nettverksadministrasjon
4843 ved Næringsakademiet i Bergen årene
2008-
2009 slik at jeg kunne
4844 forfølge en av mine største interesser - data. Til daglig jobber jeg
4845 ved
<a href=

">Parken
4846 ungdomsskole
</a
> med å drifte skolens PC-er. Har også litt
4847 musikkundervisning.
</p
>
4849 <p
>Mitt mål er å bevisstgjøre musikklærene mulighetene med de frie
4850 programmene som finnes i Skolelinux, blant annet Rosegarden.
</p
>
4852 <p
>Har i mange år drevet med musikk og en av grunnen til at Rosegarden
4853 falt i smak for min del, var fordi denne fungere og ligner mest på
4854 Windows-programmet (cubase) jeg jobbet mye med da jeg i mine yngre
4855 dager var «Windows fanatiker». Ble introdusert til Linux av en kompis
4856 av meg for omtrent
14 år siden, og har bare blitt mer og mer glad i
4857 dette operativsystemet.
</p
>
4859 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
4861 <p
>Da jeg ble sykemeldt fra min gamle jobb, og måtte omskoleres,
4862 havnet jeg i
2007 sammen med Viggo Fedreheim på IKT-avdelingen i
4863 Narvik kommune, der ble jeg for første gang introdusert til
4864 Skolelinuxprosjektet.
</p
>
4866 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
4868 <p
>Skolelinux er enkelt å holde i drift og masse flotte programmer som
4869 geogebra, ktouch og kgeografi følger med pakken. Man kan ta i bruk
4870 gamle PC-er igjen, slik at skoler med dårlig råd får opp en brukbar
4871 PC-park. PC-er som er ca
6-
9 år gamle fungere tilfredstillende, bare
4872 de har
512 MB RAM eller mer.
</p
>
4874 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
4876 <p
>Ulempene er at noen av de pedagogiske programmene som lærene ønsker
4877 å bruke fungere dårlig med Linux. Mye pga. av at disse programmene
4878 blir ikke laget til Linuxbaserte operativsystemer.
</p
>
4880 <p
>Video- og bilde-redigering har dessverre en del mangler, mange av
4881 programmene har en tendens til og krasje. Det gjelder blant annet
4882 <a href=
"http://www.kdenlive.org/
">kdenlive
</a
> og
4883 <a href=
"http://www.openshotvideo.com/
">openshot
</a
>, for å nevne
4884 noen. De er ikke stabile nok. Når elevene kommer med filmsnutter de
4885 ønsker og jobbe med, så godtar ikke programmene filene, og når elevene
4886 jobber med redigering bare krasjer programmene uten forvarsel. Det er
4887 for vanskelig å få noe som bare fungerer ut av boksen her. Når en elev
4888 plugger inn et videokamera eller fotoapparat så er det alltid noe som
4889 ikke vil fungere. Programmene godtar ikke format, godtar ikke
4890 kameraet, osv., osv. Det er dessverre med på og dra ned en positiv
4891 opplevelse av bruk av fri programvare.
</p
>
4893 <p
>Man må ofte bruke flere en et video redigerings program før og få
4894 fullført en ønsket oppgave.
</p
>
4896 <p
>Eksempel:
</p
>
4898 <p
>Hvis det ene programmet ikke vil ta i mot videofilen klarer et
4899 annet det, men det programmet som klarer det kan ikke gjøre de samme
4900 oppgavene som det programmet som ikke ville ta i mot filen,
4901 Tilsvarende er det med foto, man må bruke flere programmer for å få
4902 et ferdig resultat. Til dags dato har jeg enda ikke funnet et video-
4903 og fotoprogram som kan tilfredstillende fullføre en oppgave.
</p
>
4905 <p
>Så man kan klare og fullføre en oppgave, men i verste fall må man
4906 innom
3-
4 programmer for å få det til. Så jeg har enda ikke til dags
4907 dato sett at et program fungere
100% til alt.
</p
>
4909 <p
>Det programmet jeg har best erfaring til er
4910 <a href=
"http://cinelerra.org/
">cinelerra
</a
>, men dessverre har det
4911 også tendenser og krasje av og til uten grunn.
</p
>
4913 Lydsystemet kan også være et mareritt. Konkret snakker jeg om når du
4914 bruker for eksempel et smartboard, så følger det med USB-lydkort på
4915 disse. Problemet ligger her i at systemet ikke vil velge rett
4916 lydkort, så man må inn med padevchooser for å sette opp PulseAudio
4917 til og velge at USB-lydkortet skal brukes. Det blir for tungvindt for
4918 lærene, de ønsker at ting skal fungere med en gang. (min løsning på
4919 det problemet ble at jeg måtte deaktivere lydkortet som fantes på
4920 maskinen) men da må man bestandig slå på smartboard-tavla.
4922 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
4924 Programmene jeg bruker mest av er: Rosegarden, jack, qsynth, audacity,
4925 k3b, openttd og libreoffice.
4927 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
4928 skoler til å ta i bruk fri programvare?
</strong
></p
>
4930 Jeg tror det må bevisstgjøring av Skolene til, dvs. reklamere høylytt
4931 og fortelle og vise de andre skolene at frie programvarer faktisk
4932 fungere. Jeg trur faktisk mange ikke vet at det finnes frie

>It has been a few busy weeks for me, but I am finally back to
4943 publish another interview with the people behind
4944 <a href=
"http://www.skolelinux.org/
">Debian Edu and Skolelinux
</a
>.
4945 This time it is one of our German developers, who have helped out over the
4946 years to make sure both a lot of major but also a lot of the minor
4947 details get right before release.
4949 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
4951 <p
>My name is Jürgen Leibner, I
'm
49 years old and living in
4952 Bielefeld, a town in northern Germany. I worked nearly
20 years as
4953 certified engineer in the department for plant design and layout of an
4954 international company for machinery and equipment. Since
2011 I
'm a
4955 certified technical writer (tekom e.V.) and doing technical
4956 documentations for a steam turbine manufacturer. From April this year
4957 I will manage the department of technical documentation at a
4958 manufacturer of automation and assembly line engineering.
</p
>
4960 <p
>My first contact with linux was around
1993. Since that time I used
4961 it at work and at home repeatedly but not exclusively as I do now at
4962 home since
2006.
</p
>
4964 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4965 project?
</strong
></p
>
4967 <p
>Once a day in the early year of
2001 when I wanted to fetch my
4968 daughter from primary school, there was a teacher sitting in the
4969 middle of
20 old computers trying to boot them and he failed. I helped
4970 him to get them booting. That was seen by the school director and she
4971 asked me if I would like to manage that the school gets all that old
4972 computers in use. I answered:
"Yes
".
</p
>
4974 <p
>Some weeks later every of the
10 classrooms had one computer
4975 running Windows98. I began to collect old computers and equipment as
4976 gifts and installed the first computer room with a peer-to-peer
4977 network. I did my work at school without being payed in my spare time
4978 and with a lot of fun. About one year later the school was connected
4979 to Internet and a local area network was installed in the school
4980 building. That was the time to have a server and I knew it must be a
4981 Linux server to be able to fulfil all the wishes of the teachers and
4982 being able to do this in a transparent and economic way, without extra
4983 costs for things like licence and software. So I searched for a
4984 school server system running under Linux and I found a couple of
4985 people nearby who founded
'skolelinux.de
'. It was the Skolelinux
4986 prerelease
32 I first tried out for being used at the school. I
4987 managed the IT of that school until the municipal authority took over
4988 the IT management and centralised the services for all schools in
4989 Bielefeld in December of
2006.

4991 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4992 Edu?
</strong
></p
>
4994 <p
>When I
'm looking back to the beginning, there were other advantages
4995 for me as today.
</p
>
4997 <p
>In the past there were advantages like:
</p
>
5001 <li
>I don
't need to buy it so it generates no costs to the school as
5002 they had little money to spent for computers and software.
</li
>
5004 <li
>It has a licence which grands all rights to use it without
5007 <li
>It was more able to fit all requirements of a server system for
5008 schools than a Microsoft server system, even if there are only Windows
5009 clients because of it
's preconfigured overall concept of being a
5010 infrastructure solution and community for schools, not only a
5013 <li
>I was able to configure the server to the needs of the
5016 </ul
></p
>
5018 <p
>Today some of the advantages has been lost, changed or new ones
5019 came up in this way:
</p
>
5023 <li
>Most schools here do have money to buy hardware and software
5026 <li
>They are today mostly managed from central IT departments which
5027 have own concepts which often do not fit to Debian Edu concepts
5028 because they are to close to Microsoft ideology.
</li
>
5030 <li
>With the Squeeze version of Debian Edu which now uses GOsa² for
5031 management I feel more able to manage the daily tasks than with the
5032 interfaces used in the past.
</li
>
5034 <li
>It is more modular than in the past and fits even better to the
5035 different needs.
</li
>
5037 <li
>The documentation is usable and gets better every day.
</li
>
5039 <li
>More people than ever before are using Debian Edu all over the
5040 world and so the community, which is an very important part I think,
5041 is sharing knowledge and minds.
</li
>
5043 <li
>Most, maybe all, of the technical requirements for schools are
5044 solved today by Debian Edu.

>
5048 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
5049 Edu?
</strong

>
5053 <li
>There are too few IT companies able to integrate Debian Edu into
5054 their product portfolio for serving schools with concepts or even
5055 whole municipality areas.
</li
>
5057 <li
>Debian Edu has beside other free and open software projects not
5058 enough lobbyists which promote free and open software to
5059 politicians.

5061 <li
>Technically there are no disadvantages I
'm aware of.

>
5065 <p
><strong
>Which free software do you use daily?
</strong
></p
>
5067 <p
>I use Debian stable on my home server and on my little desktop
5068 computer. On my laptop I use Debian testing/sid. The applications I
5069 use on my laptop and my desktop are Open/Libre-office, Iceweasel,
5070 KMail, DigiKam, Amarok, Dolphin, okular and all the other programs I
5071 need from the KDE environment. On console I use newsbeuter, mutt,
5072 screen, irssi and all the other famous and useful tools.
</p
>
5074 <p
>My home server provides mail services with exim, dovecot, roundcube
5075 and mutt over ssh on the console, file services with samba, NFS,
5076 rsync, web services with apache, moinmoin-wiki, multimedia services
5077 with gallery2 and mediatomb and database services with MySQL for me
5078 and the whole family. I probably forgot something.

>Da jeg googlet etter noe annet kom jeg tilfeldigvis over
5095 <a href=
"http://www.duo.uio.no/sok/work.html?WORKID=
58309">en
5096 hovedfagsoppgave
</a
> ved Universitetet i Oslo som diskuterer verdien
5097 av GPLs fire friheter for brukerne av IT-systemer. Jeg ble fascinert
5098 over det som presenteres der. Her er sammendraget:
</p
>
5100 <p
><blockquote
>
5102 <p
>Motivasjonen til å skrive denne oppgaven er en personlig undring
5103 over hvorfor det primært, og ofte eksklusivt, fokuseres på det
5104 økonomiske aspektet ved utredninger om fri programvare er et godt valg
5105 for det offentlige. Fri og produsenteid programvare bygger på
5106 fundamentalt forskjellige ideologier som kan ha implikasjoner utover
5107 økonomiske kostnader. Kunnskapskulturen som er med på å definere fri
5108 programvare er basert på åpenhet, og er en verdi i seg selv.
</p
>
5110 <p
>Oppgavens tema er programvarelisensen GPL og frihet. GPL-lisensiert
5111 programvare gir visse friheter i forhold til produsenteid
5112 programvare. Mitt spørsmål er om, og eventuelt i hvilken utstrekning,
5113 disse frihetene blir benyttet av ulike brukere og hvordan de
5114 manifesterer seg for disse brukerne. Sentrale spørsmål i oppgaven
5118 <li
>Hvordan fordeles handlekraft gjennom lisensieringen av programvaren?
</li
>
5119 <li
>Hvilke konsekvenser har programvarelisensen for de ulike brukere?
</li
>
5122 <p
>Fri programvare gir blant annet brukeren mulighet til å studere og
5123 modifisere kildekoden. Denne formen for frihet erverves gjennom
5124 kunnskap og krever at brukeren også er en ekspert. Hva skjer med
5125 frihetene til GPL når sluttbrukeren er en annen? Dette diskuteres i
5126 dialog med informantene.
</p
>
5128 <p
>Jeg har i denne oppgaven samlet inn intervjudata fra IKT-ansvarlige
5129 ved grunnskolene i Nittedal kommune, driftsansvarlig og IKT-veilederen
5130 for skolene i kommunen, samt IKT-koordinator for utdanning i Akershus
5131 fylkeskommune og bokmåloversettere av OpenOffice.org. Den empiriske
5132 delen av oppgaven er delt inn i to seksjoner; den første omhandler
5133 operativsystemet Skolelinux, den andre kontorprogrampakken
5134 OpenOffice.org.
</p
>
5136 <p
>Som vi vil se gir GPL lokal frihet og kontroll gjennom omfordeling
5137 av makt fra produsent til bruker. Brukerens makt analyseres gjennom
5138 begrepene brukermedvirkning og handlingsfrihet. Det blir også lagt
5139 vekt på strukturelle forhold rundt bruken av teknologi, og spesielt de
5140 økonomiske begrepene nettverkseksternaliteter, innlåsing og
5141 stiavhengighet. Dette er begreper av spesiell nytte når objektet som
5142 omsettes eller distribueres er et kommunikasjonsprodukt, fordi verdien
5143 til et slikt gode for en potensiell bruker avhenger av antall
5144 eksisterende brukere av godet. I tilknytning til denne problematikken
5145 inneholder oppgaven også en diskusjon rundt åpne standarder og
5148 <p
>Oppgaven konkluderer med at de «fire frihetene» som GPL-lisensen er
5149 laget for å beskytte er av avgjørende betydning for bruken av
5150 OpenOffice.org og Skolelinux, i Akershus fylkeskommune såvel som i
5151 skolene i Nittedal. Distribusjonen av handlekraft er ikke helt
5152 symmetrisk. Det er først og fremst de profesjonelle utviklerne i
5153 Skolelinux som direkte kan nyttiggjøre seg friheten til å endre kode,
5154 mens en sluttbruker som Nittedal kommune nyttiggjør seg den økonomiske
5155 friheten til å kunne distribuere programmene. Det er imidlertid også
5156 slik at ingen aktør klarer seg uten alle disse «frihetene».

</a

5174 setting together all the pieces. This time I present to you Andreas
5175 Mundt, who have been part of the technical development team several
5176 years. He was also a key contributor in getting GOsa and Kerberos set
5177 up in the recently released

5183 <p
>My name is Andreas Mundt, I grew up in south Germany. After
5184 studying Physics I spent several years at university doing research in
5185 Quantum Optics. After that I worked some years in an optics company.
5186 Finally I decided to turn over a new leaf in my life and started
5187 teaching
10 to
19 years old kids at school. I teach math, physics,
5188 information technology and science/technology.

><strong
>How did you get in contact with the Skolelinux/Debian Edu
5191 project?
</strong
></p
>
5193 <p
>Already before I switched to teaching, I followed the Debian Edu
5194 project because of my interest in education and Debian. Within the
5195 qualification/training period for the teaching, I started
5196 contributing.
</p
>
5198 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5199 Edu?
</strong
></p
>
5201 <p
>The advantages of Debian Edu are the well known name, the
5202 out-of-the-box philosophy and of course the great free software of the
5203 Debian Project!
</p
>
5205 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
5206 Edu?
</strong
></p
>
5208 <p
>As every coin has two sides, the out-of-the-box philosophy has its
5209 downside, too. In my opinion, it is hard to modify and tweak the
5210 setup, if you need or want that. Further more, it is not easily
5211 possible to upgrade the system to a new release. It takes much too
5212 long after a Debian release to prepare the -Edu release, perhaps
5213 because the number of developers working on the core of the code is
5214 rather small and often busy elsewhere.
</p
>
5216 <p
>The
<a href=
"http://wiki.debian.org/DebianLAN
">Debian LAN

>
5217 project might fill the use case of a more flexible system.
</p
>
5219 <p
><strong
>Which free software do you use daily?
</strong
></p
>
5221 <p
>I am only using non-free software if I am forced to and run Debian
5222 on all my machines. For documents I prefer LaTeX and PGF/TikZ, then
5223 mutt and iceweasel for email respectively web browsing. At school I
5224 have Arduino and Fritzing in use for a micro controller project.
</p
>
5226 <p
><strong
>Which strategy do you believe is the right one to use to
5227 get schools to use free software?
</strong
></p
>
5229 <p
>One of the major problems is the vendor lock-in from top to bottom:
5230 Especially in combination with ignorant government employees and
5231 politicians, this works out great for the
"market-leader
". The school
5232 administration here in Baden-Wuerttemberg is occupied by that vendor.
5233 Documents have to be prepared in non-free, proprietary formats. Even
5234 free browsers do not work for the school administration. Publishers
5235 of school books provide software only for proprietary platforms.
</p
>
5237 <p
>To change this, political work is very important. Parts of the
5238 political spectrum have become aware of the problem in the last years.
5239 However it takes quite some time and courageous politicians to
'free
'
5240 the system. There is currently some discussion about
"Open Data
" and
5241 "Free/Open Standards
". I am not sure if all the involved parties have
5242 a clue about the potential of these ideas, and probably only a
5243 fraction takes them seriously. However it might slowly make free
5244 software and the philosophy behind it more known and popular.

5310 <description><p
>Recently I have spent time with
5311 <a href=
"http://www.slxdrift.no/
">Skolelinux Drift AS
</a
> on speeding
5312 up a
<a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>
5313 Lenny installation using LTSP diskless workstations, and in the
5314 process I discovered something very surprising. The reason the KDE
5315 menu was responding slow when using it for the first time, was mostly
5316 due to the way KDE find application icons. I discovered that showing
5317 the Multimedia menu would cause more than
20 000 IP packages to be
5318 passed between the LTSP client and the NFS server. Most of these were
5320 NFS LOOKUP calls, resulting in a NFS3ERR_NOENT response. Because the
5321 ping times between the client and the server were in the range
2-
20
5322 ms, the menus would be very slow. Looking at the strace of kicker in
5323 Lenny (or plasma-desktop i Squeeze - same problem there), I see that
5324 the source of these NFS calls are access(
2) system calls for
5325 non-existing files. KDE can do hundreds of access(
2) calls to find
5326 one icon file. In my example, just finding the mplayer icon required
5327 around
230 access(
2) calls.
</p
>
5329 <p
>The KDE code seem to search for icons using a list of icon
5330 directories, and the list of possible directories is large. In
5331 (almost) each directory, it look for files ending in .png, .svgz, .svg
5332 and .xpm. The result is a very slow KDE menu when /usr/ is NFS
5333 mounted. Showing a single sub menu may result in thousands of NFS
5334 requests. I am not the first one to discover this. I found a
5335 <a href=
"https://bugs.kde.org/show_bug.cgi?id=
211416">KDE bug report
5336 from
2009</a
> about this problem, and it is still unsolved.
</p
>
5338 <p
>My solution to speed up the KDE menu was to create a package
5339 kde-icon-cache that upon installation will look at all .desktop files
5340 used to generate the KDE menu, find their icons, search the icon paths
5341 for the file that KDE will end up finding at run time, and copying the
5342 icon file to /var/lib/kde-icon-cache/. Finally, I add symlinks to
5343 these icon files in one of the first directories where KDE will look
5344 for them. This cut down the number of file accesses required to find
5345 one icon from several hundred to less than
5, and make the KDE menu
5346 almost instantaneous. I
'm not quite sure where to make the package
5347 publicly available, so for now it is only available on request.
</p
>
5349 <p
>The bug report mention that this do not only affect the KDE menu
5350 and icon handling, but also the login process. Not quite sure how to
5351 speed up that part without replacing NFS with for example NBD, and
5352 that is not really an option at the moment.

5382 Schweer, a valuable contributor to the project from Germany.
5384 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
5386 <p
>I
've studied Mathematics at the university
'Ruhr-Universität
' in
5387 Bochum, Germany. Since
1981 I
'm working as a teacher at the school
5388 "<a href=
"http://www.westfalenkolleg-dortmund.de/
">Westfalen-Kolleg
5389 Dortmund

>", a second chance school. Here, young adults is given
5390 the opportunity to get further education in order to do the school
5391 examination
'Abitur
', which will allow to study at a university. This
5392 second chance is of value for those who want a better job perspective
5393 or failed to get a higher school examination being teens.
</p
>
5395 <p
>Besides teaching I was involved in developing online courses for a
5396 blended learning project called
'abitur-online.nrw
' and in some other
5397 information technology related projects. For about ten years I
've been
5398 teacher and coordinator for the
'abitur-online
' project at my
5399 school. Being now in my early sixties, I
've decided to leave school at
5400 the end of April this year.
</p

5402 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5403 project?
</strong
></p
>
5405 <p
>The first information about Skolelinux must have come to my
5406 attention years ago and somehow related to LTSP (Linux Terminal Server
5407 Project). At school, we had set up a network at the beginning of
1997
5408 using Suse Linux on the desktop, replacing a Novell network. Since
5409 2002, we used old machines from the city council of Dortmund as thin
5410 clients (LTSP, later Ubuntu/Lessdisks) cause new hardware was out of
5411 reach. At home I
'm using Debian since years and - subscribed to the
5412 Debian news letter - heard from time to time about Skolelinux. About
5413 two years ago I proposed to replace the (somehow undocumented and only
5414 known to me) system at school by a well known Debian based system:
5415 Skolelinux.
</p
>
5417 <p
>Students and teachers appreciated the new system because of a
5418 better look and feel and an enhanced access to local media on thin
5419 clients. The possibility to alter and/or reset passwords using a GUI
5420 was welcomed, too. Being able to do administrative tasks using a GUI
5421 and to easily set up workstations using PXE was of very high value for
5422 the admin teachers.
</p
>
5424 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5425 Edu?
</strong
></p
>
5427 <p
>It
's open source, easy to set up, stable and flexible due to it
's
5428 Debian base. It integrates LTSP out-of-the-box. And it is documented!
5429 So it was a perfect choice.
</p
>
5431 <p
>Being open source, there are no license problems and so it
's
5432 possible to point teachers and students to programs like
5433 OpenOffice.org, ViewYourMind (mind mapping) and The Gimp. It
's of
5434 high value to be able to adapt parts of the system to special needs of
5435 a school and to choose where to get support for this.

5440 <p
>Nothing yet.
</p

5442 <p
><strong
>Which free software do you use daily?

5444 <p
>At home (Debian Sid with Gnome Desktop): Iceweasel, LibreOffice,
5445 Mutt, Gedit, Document Viewer, Midnight Commander, flpsed (PDF
5446 Annotator). At school (Skolelinux Lenny): Iceweasel, Gedit,
5447 LibreOffice.

5449 <p
><strong

5450 get schools to use free software?
</strong

5452 <p

5453 that doesn
't seem to work quite well. Now I concentrate on those more
5454 interested and hope to get multiplicators that way.

5472 <p
>Det er store forskjeller på skolenes digitale tilstand, viser
5473 undersøkelsen Monitor
2011 som er laget på oppdrag fra
5474 Kunnskapsdepartementet. Dette har ført til debatt om PC-tilgangen i
5475 skolen, og om de med Linux i skolen gjør det bedre bedre eller
5476 dårligere enn snittet i landet.
</p
>
5478 <p
>Nå har vi tallene. Skoler med Linux har
36% større PC-tetthet en
5479 landsgjennomsnittet. På spørsmål hvorfor skoler med Linux har større
5480 PC-tetthet, observerer Paul Reidar Løsnesløkken som er IKT-konsulent i
5481 Nord-Odal:
</p
>
5483 <p
><blockquote
>"Vi erfarer at klienter med Skolelinux har god funksjon
5484 til de er
8 til
10 år gamle. Dette er omtrent dobbelt så lenge som
5485 andre løsninger, og skolene får mer datautstyr for
5486 pengene.
"</blockquote
></p
>
5488 <p
>Undersøkelsen baserer seg på
56 skoler som har gjort det offentlig
5489 at de kjører Skolelinux eller annen Linux-utgave. De kan også ha PC-er
5490 med Windows i skolenettet. Når en sammenligner PC-tetthetene på
5491 skolene i kommunene Flora, Harstad, Kongsvinger, Narvik, Nittedal,
5492 Nord-Odal og Randaberg, er det i snitt
2,
28 elev pr. PC på skolene med
5493 Linux. På landsbasis er det
3.11 elev per PC i grunnskolen, i følge
5494 side
95 i Monitor-rapporten for
2011. Målingen viser dermed
36% større
5495 PC-tetthet i skoler med Linux.

>Skolelinux har til hensikt å gi alle barn full tilgang til
5500 skoleaktuelle dataprogram på sitt eget morsmål. Derfor følger det med
5501 godt over
100 skoleaktuelle programmene laget for læring. De fleste
5502 programmene er oversatt til over
50 språk. Elevene skal også kunne
5503 studere alle sider av dataprogrammene. Derfor følger også kildekode
5504 med. Elever med interesse kan lære av eksperter som har laget
5505 systemet. Dette med enkelt programmering i læreprogram som KTurtle,
5506 til profesjonelle verktøy som Qt Creator eller Java.
</p
>
5508 <p
>Skolelinux er laget for sentralisert drift, der alt teknisk
5509 administrasjon av alle skolene kan gjøres sentralt fra kommunehuset
5510 eller sentralt i en region. F.eks. drifter to-tre personer
70.000
5511 skoledatamaskiner på
200 skoler i delstaten Extremadura i
5512 Spania. Etter velykket bruk av Debian Edu i skolen, legger delstaten
5513 over til Debian på
40.000 datamaskiner i administrasjonen. Det er idag
5514 mange selskap som tilbyr profesjonell støtte til innføring og drift i
5515 Norge og verden.

>I serien med intervjuer av folk i
5553 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet, får vi
5554 denne gangen høre fra en IKT-ansvarlig som har brukt Skolelinux i
5555 mange år, og vært storfornøyd med erfaringene så langt.
</p
>
5557 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
5559 <p
>Mitt navn er Roy-Arne Myhre og jeg er
42 år. Jeg er ansatt hos
5560 <a href=
"http://www.sandskole.no/
">Sand skole
</a
> (Balsfjord kommune)
5561 og har stort sett vært det siden
1990. Jeg er IKT ansvarlig ved
5562 skolen i
40% stilling –
10% undervisning – musikk.
</p
>
5564 <p
>Ved skolen er det ca
100 elever og ca
18 lærere +
4 assistenter i
5565 hele og delte stillinger. Alle lærerne har bærbar PC (dessverre med
5566 Win Vista) – assistenter har tilgang til egne. Vi benytter Fronter i
5567 det daglige arbeidet. Vi har ca
90 elevmaskiner som fungerer til
5568 daglig opp mot Linux server (XFCE) som driftes av
5569 <a href=
"http://www.bzz.no/
">BzzWare AS
</a
> via nett. Maskinparken
5570 består kun av brukt utstyr for elevene – og noe av dette begynner å
5571 bli vel gammelt selv som halvtykke klienter.
</p
>
5573 <p
><strong
>Hvordan kom du i kontakt med
5574 Skolelinux-prosjektet?
</strong
></p
>
5576 <p
>Vi kom første gang i kontakt med Skolelinux rundt
1997. Den gang
5577 var det oppstart-disketter i hver maskin, ikke mulighet for lyd og
5578 video, gamle nettverkskort og mye plundring. Vi hadde en ihuga
5579 forelder med som pådriver, forsker og inspirator for hele opplegget.
5580 Selv ante jeg knapt at Skolelinux fantes, men han var av den
5581 utforskende typen, og fikk både meg og skolelederen i trua på at dette
5582 var ting som kunne fungere. Etter dette har det gått gradvis
5583 framover; flere maskiner er hentet inn gjennom bl.a
5584 <a href=
"http://www.greentech.no/
">Greentech
</a
> og utrangert utstyr
5585 fra høgskole / Avinor og private givere. Når maskinene ble for trege
5586 for nye Windows-versjoner, sto vi klare til å putte dem i nettverket
5587 vårt. Dette betyr at vi i dag har
1:
1 dekning av maskiner på
5588 ungdomstrinnet og bedre enn
1:
2 på barnetrinnet. Dette er vi veldig
5589 fornøyd med, og vi kan ikke se for oss hverdagen som ville vært
5590 alternativet ved bruk av Windows med sine lisenser pr. Bruker/maskin.
5591 Da ville vi nok vært tilbake til
1-
2 maskiner pr klasserom med de
5592 negative konsekvenser det ville hatt for undervisningsformene våre. Vi
5593 kan ha en hel klasse i prosjektjobbing eller individuell jobbing
5594 samtidig – vi kan avholde tentamen og eksamen uten
5595 logistikkproblemer.
</p
>
5597 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
5599 Hvor skal jeg begynne... Stabiliteten er et nøkkelord - det bare
5600 virker. Har du først fått en server med Skolelinux opp og gå, så må
5601 det en maskinarefeil eller sabotasje til for å stoppe den. Det at man
5602 kan bruke eldre maskiner som normalt sett ville gått på dynga, er også
5603 glimrende - billig for skoler med dårlig økonomi og bra for miljøet
5604 siden vi gjenbruker utstyr i stedet for å skaffe nytt. Vi ville aldri
5605 hatt mulighet til å operere med det maskinantallet vi har pr i dag
5606 hvis det ikke var for Skolelinux - så tilgjengelighet er et annet
5607 nøkkelord. Et tredje moment er sikkerhet og brukertilgang. Alle
5608 brukerer opererer med egne brukernavn og passord, samt egne
5609 brukerområder som kan tilpasses for både enbrukertilgang og for
5610 samarbeid med andre.
5612 Elever har godt av å se at det finnes andre alternativer enn de som
5613 storindustrien selger på lisensbasis - på den måten trenes de opp til
5614 å se flere muligheter og å foreta valg ut fra flere opsjoner.
5616 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
5618 <p
>Ulempene med Skolelinux er nok utbredelsen og mangelen på kjennskap
5619 til dette i skolenorge. De som skal ta økonomiske avgjørelser rynker
5620 på nesen og vil gå for det kjente og «sikre» selv om det koster mye
5621 mer. Man får rett og slett litt hetta av å ikke kunne noe – og unngår
5622 dette for enhver pris.
</p

5624 <p
>I tillegg er mye av linux-systemet administrert av tekstkommandoer
5625 og er lite intuitiv/visuell for oss som ikke er «inne i»
5626 kildekodene». Så problemet er nok mye godt at de som
5627 utarbeider/drifter Skolelinux ikke helt klarer å sette seg ned på
5628 skoleadministratorens nivå når det gjelder problemer og
5629 utfordringer. Men dette er nok en utfordring alle administratorer
5630 sliter med uansett OS.
</p

5632 <p
>Derfor har vi valgt å støtte oss til BzzWare AS for assistanse i
5633 drifta slik at jeg har kunnet konsentrere meg mer om kabling, skifting
5634 av komponenter, veiledning av lærere og elever, vedlikehold av
5635 skrivere og annen daglig drift.
</p
>
5637 <p
>Elevene mestrer Skolelinux helt fint. Så lenge Internett
5638 (Iceweasel) og Libreoffice (Openoffice) fungerer er
90% av
5639 skolehverdagen velfungerende. I tillegg brukes jo en del av den
5640 pedagogiske programpakken bla. i forhold til matematikk og geografi,
5641 men det er såpass mye bra på nett om dagen, så disse programmene er
5642 mer som krydder å regne.
</p
>
5644 <p
>Jeg skulle ønske neste versjon av Skolelinux kunne komme litt
5645 mindre stappet med programmer, for halvparten blir aldri brukt, eller
5646 fungerer ikke uansett. Hva med et pedagogisk panel av lærere/IKT
5647 ansvarlige som kunne sagt: disse programmene skal være standard, så
5648 får resten være slike man kan legge til ved behov – det kan lett bli
5649 en jungel å bevege seg i.
</p

5651 <p
>Jeg ønsker meg også en mer grafisk versjon av
5652 <a href=

</a
> hvor man kan krysse
5653 ut de som f.eks ikke skal ha internett-tilgang en dag pga
5654 eksamen/tentamen, samt en noe enklere brannmurløsning hvor man kan
5655 stenge for en del (få) sider på en enkel måte. Jeg liker godt
5656 Skolelinux sin ideologi om at filteret skal trenes i hodet på eleven –
5657 men av og til skulle jeg ønske at f.eks Facebook og Youtube kunne vært
5658 koblet vekk en periode for å få bedre utnyttelse av tid og
5659 ressurser. Disse to nettstedene er nok mye av årsaken til at mange
5660 lærere holder igjen databruken noe mer enn man kunne ønske.
</p

5662 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
5664 Jeg benytter nesten bare fri programvare til daglig. LibreOffice,
5665 Iceweasel (Firefox), Thunderbird til e-post og Gimp til
5666 bildebehandling. Vi har PHP-Nuke-oppsatt hjemmeside. Det eneste som
5667 jeg ikke har fått helt til enda er videoredigering - her må man vel
5668 innrømme at Mac er hakket over, men da er vi igjen over på å se hva
5669 som egner seg best, og ta valg ut fra det. Folk flest lever i
5670 villfarelsen om at regneark HETER Excel og tekstbehandling HETER
5671 Word. Dette er en misforståelse som jeg bruker mye energi på å
5672 diskutere og
"åpne sinn
" på Microsoft-slaver. Dessverre er det mange
5673 IKT-ansvarlige som også har låst seg på at det eneste saliggjørende er
5674 Bill G sine produkter.
5676 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
5677 skoler til å ta i bruk fri programvare?
</strong
></p
>
5679 <p
>For å komme lenger i utbredelsen av Skolelinux tror jeg det må mer
5680 fram i nasjonale medier, samt komme bedre fram hva økonomien i dette
5681 valget vil være – samt mulighetene. Fri programvare er en berikelse og
5682 gjør oss i stand til å utføre arbeidet i skolen uten å måtte legge
5683 igjen tusener på tusener i Bill Gates lomme.. Få ETT nettsted med
5684 forståelig veiledning av installasjon/oppgradering og ETT forum med
5685 konkrete feilrettinger og problemer, så tror jeg vi kunne kommet et
5686 par skritt framover. Ellers tror jeg bare at ildsjelene må fortsette å
5687 skinne – kanskje flere enn oss følger etter på veien.

>Den siste uka har det vært en del skriverier om hvor store
5722 forskjeller det er mellom skolene når det gjelder digital kompetanse.

"http://www.digi.no/

">oppslaget
5725 i Digi
</a
>. Diskusjonen fikk meg til å bli litt nysgjerrig på om
5726 Linux-skoler har større PC-tettet enn snittet i landet. Grunnlaget
5727 for diskusjonen har vært undersøkelsen
5728 <a href=
"https://iktsenteret.no/ressurser/monitor-
2011-skolens-digitale-tilstand

"https://www.wis.no/gsi
">Grunnskolens Informasjonssystem
</a

5731 (GSI). GSI-data kan lastes ned fra web og jeg lastet ned en Excel-fil
5732 (intet åpen standard-valg tilgjengelig) med navn på alle skoler,
5733 hvilke kommune de befinner seg i og hvor mange elever pr. elev-PC de
5734 har rapportert inn. For å få en ide om svaret trenger jeg deretter å
5735 vite hvilke skoler i landet som bruker Linux, slik at jeg kan slå dem
5736 opp i GSI og finne ut hvor stor PC-tetthet de har.
</p
>
5738 <p
>Jeg vet om skoler i Balsfjord, Flora, Harstad, Kongsvinger, Narvik,
5739 Nittedal, Nord-Odal, Randaberg og Sunndal som bruker Skolelinux eller
5740 andre Linux-varianter. Jeg tror det er flere enn de
56 skolene jeg
5741 har klart å identifisere de siste dagene, men har ikke klart å få det
5742 bekreftet med offentlige kilder.
</p
>
5744 <p
>Monitor
2011-rapporteres side
95 forteller at det
"ifølge GSI
5745 (
20120-
2011) er det
3,
11 elever per datamaskin når vi tar med alle
5746 grunnskoler (
1.-
10.trinn)
". For de
56 Linux-skolene jeg har klart å
5747 koble mot informasjon i GSI er det
2,
28 elever per elevdatamaskin,
5748 hvilket betyr at det er
36% høyere PC-tetthet på Linux-skoler enn
5749 landsgjennomsnittet. Linux-skolen med høyest tettet blant de jeg har
5750 notert -skole er Flora ungdomsskule i Flora kommune med
0.82 elev
5751 pr. PC (
482 elever,
588 elevdatamaskiner).
</p
>
5753 <p
>Skolelinux gir datamaskiner lengre levetid, og en kan dermed få
5754 flere operative datamaskiner for samme budsjett, i tillegg til en
5755 rekke andre fordeler. Kan det være forklaringen på forskjellen?
</p
>
5757 <p
>Tallene må tas med en liten klype, da GSI ser ut til å ha endel
5758 feilføringer. Jeg synes i hvert fall en skole med
423 elever og
9
5759 elevmaskiner ser mistenkelig ut. Eller en skole med
346 elever,
0
5760 elevmaskiner, som er et annet ekstremt eksempel jeg fant.

5780 <p
>I teach ICT part time at the Rudolf Steiner School in Kings
5781 Langley, near London, UK. Previously I worked as a technical
5782 author/trainer while my children attended the school, and I also
5783 contributed to the Schoolforge UK community with the aim of
5784 encouraging UK schools to adopt free/open source software. Five or six
5785 years ago we had about
50 schools interested in some way, but we
5786 weren
't able to convert many of them into sustainable
5787 installations.
</p
>
5789 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5790 project?
</strong
></p
>
5792 <p
>Skolelinux had two representatives at an early Edubuntu meeting in
5793 London which I attended. However at that time our school network had
5794 just been installed using CentOS, LTSP
4 and GNOME. When LTSP
5 came
5795 along we switched to Edubuntu thin client servers so now we have a
5796 mixed environment which includes Windows PCs and student laptops, as
5797 well as their MacBooks and iPads. However, the proprietary systems
5798 have always been rather problematic, and we never built a GUI for the
5799 LDAP server, so when I discovered Skolelinux is configured for all
5800 these things we decided to try it.
</p

5802 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5803 Edu?
</strong
></p
>
5805 <p
>By far the biggest advantage is the Debian Edu community. Apart
5806 from that I have always believed in the same
"sustainable computing
"
5807 goals that Skolelinux is built on: installing Linux on computers which
5808 would otherwise be thrown away, to provide a reliable, secure and
5809 low-cost IT environment for schools. From my own experience I know
5810 that a part-time person can teach and manage a network of about
25
5811 Linux computers, but it would take much more of my time if we had
5812 proprietary software everywhere.

5817 <p
>As a newcomer I
'm just finding out who
's who in the community and
5818 how you
're organised, and what your procedures are for dealing with
5819 various things such as editing manual pages and so-on. The only
5820 English language mailing list seems to be for developers as well as
5821 users, so my inbox needs heavy pruning each day!

5823 <p
><strong
>Which free software do you use daily?
</strong

5825 <p
>Besides the software already mentioned at school we use Samba,
5826 OpenLDAP, CUPS, Nagios and Dansguardian for the network, and on the
5827 desktops we have LibreOffice, Firefox, GIMP and Inkscape. At home I
5828 use Ubuntu and an Android
4 eePad Transformer (but I
'm not sure if
5829 that counts...)
</p

5831 <p
><strong
>Which strategy do you believe is the right one to use to
5832 get schools to use free software?
</strong
></p
>
5834 <p
>That
's a tough question! For very many years UK schools installed
5835 and taught only proprietary software, so that at the highest levels
5836 the notion of
"computer
" means simply
"proprietary office
5837 applications
". However, schools today are experiencing budget
5838 constraints, and many are having to think hard about upgrading Windows
5839 XP. At the same time, we have students showing teachers how to use
5840 iPads, MacBooks and Android, so the choice of operating system is no
5841 longer quite so automatic. What is more, our government at last
5842 realised that we need people with programming skills, so they
're
5843 putting coding back in the curriculum! And it
's encouraging that the
5844 first
10,
000 Raspberry Pi units sold out in
2 hours.
</p
>
5846 <p
>I don
't really know what strategy is going to get UK schools to use
5847 free software, but building an active community of Skolelinux/Debian
5848 Edu users in this country has to be part of it.

5858 it is important to make it both easy to contribute and to keep the

5860 believe is a very efficient work flow.
</p

5864 <li
>The documentation is written in a
5865 <a href=

</a

5866 <a href=

5868 docbook XML.
</li
>
5870 <li
>This docbook document is given to po4a to extract a gettext style
5871 .pot file with the content, which in turn is used to create .po files
5872 with the translated text.
</li
>
5874 <li
>The .po files are given to translators, and they can always tell
5875 which part of the original wiki document is new or changed. They can
5876 use their normal translation tools like lokalize or poedit to write
5877 the translation. There is even a system in place to handle translated
5880 <li
>The translated .po files are combined with the original docbook
5881 XML document using po4a to create a translated docbook document.
</li
>
5883 <li
>The final step is to use all the generated docbook files and
5884 create PDF and HTML version of the original and translated documents.
</li
>
5888 <p
>This setup work very well, but have a few issues. The biggest
5889 issue is that
<a href=
"http://moinmo.in/DocBook
">the docbook support
5890 we use in moinmoin
</a
> is not actively maintained. The docbook
5891 support is also buggy, and our build system contain workarounds to
5892 make sure the generated docbook is usable despite these bugs.

2012 er jeg valgt inn som styremedlem i

5951 <p
>Jeg hørte om det først når jeg jobbet i Redpill Linpro. Men jeg
5952 har også en datter som går på en friskole, som også bruker Skolelinux.
5953 Som kjent har ikke friskoler de samme økonomiske rammebetingelsene som
5954 offentlige skoler, så for dem var det det absolutt beste alternativet.
5955 De anser også Skolelinux som et stabilt system, som bare går og går (i

5962 lydløse og raskere arbeidsstasjoner som er bedre i klasserommet.
5963 Lengre levetid på PC
'er. Store besparelser på maskinvare og drift. Og
5964 så klart fjerning av alle lisenskostnader. Personlig synes jeg også at
5965 mange av programmene er bedre enn alternativene. Men dette er ofte en
5966 smakssak og avhengig om man må ha det man er vant til fra før.

5971 kompatibilitet med arbeidsstasjoners/bærbare maskiner sine
5972 nettverksdrivere eller skjermkort. Men dette løser vi i skolene ved
5973 standardisering. Ellers er det få, om nesten ingen, av de kjente
5974 maskinvare / infrastruktur leverandørene til fylkes- / kommuner som
5975 tilbyr denne plattformen. Skal dette endre seg så må kommunene selv
5976 sette slike krav til leverandørene.

>Fortsette å presentere flere av de gode eksemplene hvor Debian Edu
5989 / Skolelinux brukes i kommuner og enkeltskoler. Vi må få bedre frem
5990 at det er mulig tilknytte både Windows og Mac klienter på denne
5991 plattformen (selv om det vil øke driftskostnadene). Dette gjøres
5992 mange steder. Spesielt er det mange lærere som ønsker å bruke
5993 Windows/Mac-bærbare, gjerne som sin private PC også. Det er også mulig
5994 for kommunen å integrere med Active Directory i stedet for OpenLDAP
5995 som kommer med ut av boksen (selv om også dette øker kostnadene).
5996 Dette vil muligens bidra til å fjerne noe motstand hos noen
5997 potensielle brukere / driftpersonell for å ta i bruk noe
5998 nytt. Fremveksten av mobile brukere og nettbrett går i vår favør.
5999 Brukerne blir kjent og vant til flere nye operativsystemer /
6000 brukergrensesnitt. Så utviklerfellesskapet bør jobbe videre med å
6001 integrere flere nye klienttyper, som ultra lav-kostklienter og

>Inspired by
<a href=
"http://raphaelhertzog.com/tag/interview/
">the
6034 interview series
</a
> conducted by Raphael, I started a Norwegian
6035 interview series with people involved in the Debian Edu / Skolelinux
6036 community. This was so popular that I believe it is time to move to a
6037 more international audience.
</p
>
6039 <p
>While
<a href=
"http://www.skolelinux.org/
">Debian Edu and
6040 Skolelinux
</a
> originated in France and Norway, and have most users in
6041 Europe, there are users all around the globe. One of those far away
6042 from me is Nigel Barker, a long time Debian Edu system administrator
6043 and contributor. It is thanks to him that Debian Edu is adjusted to
6044 work out of the box in Japan. I got him to answer a few questions,
6045 and am happy to share the response with you. :)
6048 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
6050 <p
>My name is Nigel Barker, and I am British. I am married to Yumiko,
6051 and we have three lovely children, aged
15,
14 and
4(!) I am the IT
6052 Coordinator at Hiroshima International School, Japan. I am also a
6053 teacher, and in fact I spend most of my day teaching Mathematics,
6054 Science, IT, and Chemistry. I was originally a Chemistry teacher, but
6055 I have always had an interest in computers. Another teacher teaches
6056 primary school IT, but apart from that I am the only computer person,
6057 so that means I am the network manager, technician and webmaster,
6058 also, and I help people with their computer problems. I teach python
6059 to beginners in an after-school club. I am way too busy, so I really
6060 appreciate the simplicity of Skolelinux.
</p
>
6062 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
6063 project?
</strong
></p
>
6065 <p
>In around
2004 or
5 I discovered the ltsp project, and set up a
6066 server in the IT lab. I wanted some way to connect it to our central
6067 samba server, which I was also quite poor at configuring. I discovered
6068 Edubuntu when it came out, but it didn
't really improve my setup. I
6069 did various desperate searches for things like
"school Linux server
"
6070 and ended up in a document called
"Drift
" something or other. Reading
6071 there it became clear that Skolelinux was going to solve all my
6072 problems in one go. I was very excited, but apprehensive, because my
6073 previous attempts to install Debian had ended in failure (I used
6074 Mandrake for everything - ltsp, samba, apache, mail, ns...). I
6075 downloaded a beta version, had some problems, so subscribed to the
6076 Debian Edu list for help. I have remained subscribed ever since, and
6077 my school has run a Skolelinux network since Sarge.
</p
>
6079 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
6080 Edu?
</strong
></p
>
6082 <p
>For me the integrated setup. This is not just the server, or the
6083 workstation, or the ltsp. Its all of them, and its all configured
6084 ready to go. I read somewhere in the early documentation that it is
6085 designed to be setup and managed by the Maths or Science teacher, who
6086 doesn
't necessarily know much about computers, in a small Norwegian
6087 school. That describes me perfectly if you replace Norway with
6090 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
6091 Edu?
</strong
></p
>
6093 <p
>The desktop is fairly plain. If you compare it with Edubuntu, who
6094 have fun themes for children, or with distributions such as Mint, who
6095 make the desktop beautiful. They create a good impression on people
6096 who don
't need to understand how to use any of it, but who might be
6097 important to the school. School administrators or directors, for
6098 instance, or parents. Even kids. Debian itself usually has ugly
6099 default theme settings. It was my dream a few years back that some
6100 kind of integration would allow Edubuntu to do the desktop stuff and
6101 Debian Edu the servers, but now I realise how impossible that is. A
6102 second disadvantage is that if something goes wrong, or you need to
6103 customise something, then suddenly the level of expertise required
6104 multiplies. For example, backup wasn
't working properly in Lenny. It
6105 took me ages to learn how to set up my own server to do rsync backups.
6106 I am afraid of anything to do with ldap, but perhaps Gosa will
6109 <p
><strong
>Which free software do you use daily?
</strong
></p
>
6111 <p
>Nowadays I only use Debian on my personal computers. I have one for
6112 studio work (I play guitar and write songs), running AV Linux
6113 (customised Debian) a netbook running Squeeze, and a bigger laptop
6114 still running Skolelinux Lenny workstation. I have a Tjener in my
6115 house, that
's very useful for the family photos and music. At school
6116 the students only use Skolelinux. (Some teachers and the office still
6117 have windows). So that means we only use free software all day every
6118 day. Open office, The GIMP, Firefox/Iceweasel, VLC and Audacity are
6119 installed on every computer in school, irrespective of OS. We also
6120 have Koha on Debian for the library, and Apache, Moodle, b2evolution
6121 and Etomite on Debian for the www. The firewall is Untangle.
</p
>
6123 <p
><strong
>Which strategy do you believe is the right one to use to
6124 get schools to use free software?
</strong
></p
>
6126 <p
>Current trends are in our favour. Open source is big in industry,
6127 and ordinary people have heard of it. The spread of Android and the
6128 popularity of Apple have helped to weaken the impression that you have
6129 to have Microsoft on everything. People complain to me much less about
6130 file formats and Word than they did
5 years ago. The Edu aspect is
6131 also a selling point. This is all customised for schools. Where is the
6132 Windows-edu, or the Mac-edu? But of course the main attraction is
6133 budget.The trick is to convince people that the quality is not
6134 compromised when you stop paying and use free software instead. That
6135 is one reason why I say the desktop experience is a weakness. People
6136 are not impressed when their USB drive doesn
't work, or their browser
6137 doesn
't play flash, for example.

>Many years ago, the
<a href=
"http://www.skolelinux.org/
">Skolelinux
6184 / Debian Edu project
</a
> initiated a student project to create a tool
6185 for making stop motion movies. The proposal came from a teacher
6186 needing such tool on Skolelinux. The project, called
"stopmotion
",
6187 was manned by two extraordinary students and won a school award and a
6188 national aware with this great project. The project was initiated and
6189 mentored by Herman Robak, and manned by the students Bjørn Erik Nilsen
6190 and Fredrik Berg Kjølstad. They got in touch with people at Aardman
6191 Animation studio and received feedback on how professionals would like
6192 such stopmotion tool to work, and the end result was and is used by
6193 animators around the globe. But as is usual after studying, both got
6194 jobs and went elsewhere, and did not have time to properly tend to the
6195 project, and it has been lingering for a few years now. Until last
6198 <p
>Last year some of the users got together with Herman, and moved the
6199 project to Sourceforge and in effect restarted the project under a new

"http://sourceforge.net/projects/linuxstopmotion/
">linuxstopmotion
</a
>.
6202 The name change was done to make it possible to find the project using
6203 Internet search engines (try to search for
'stopmotion
' to see what I
6204 mean). I
've been following
6205 <a href=
"https://lists.sourceforge.net/lists/listinfo/linuxstopmotion-community

6206 mailing list

>Knut Yrvin her. Jobber i Nokia med å fremme rammeverket Qt og QML
6285 med tilhørende utviklerverktøy. Rollen er som leder av
6286 friprog-samfunn. I fjor var jeg med å legge om utviklingen av Qt til
6287 åpen forvaltning. På den måten kan alle som bidrar til Qt gjøre det
6288 på like vilkår. Nå er det

6290 1000 utviklere

6293 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
6295 <p
>Jeg var en av initiativtagerne til Skolelinux i
2001. Skolene slet
6296 med både utstyr og Internett-tilgang. De klarte ikke å møte
6297 forventningene til data i skolen. Driften av PC-ene var uholdbar. Som
6298 regel hadde rektor pekt ut en ivrig lærer til å passe på PC-ene,
6299 gjerne naturfaglæreren. Mange lærere jobbet mye ubetalt overtid for å
6300 vedlikeholde
30-
40 datamaskiner på hver sin skole. Med
300 elever og
6301 lærere som brukere, blir det fort mye mer arbeid enn de
4-
8 timene de
6302 kunne bruke på PC-drift. Skolene hadde kun en femtedel av
6303 IT-budsjettet som ble brukt på PC-ene i rådhuset.
</p
>
6305 <p
>Vi erfarte at skolene hadde mye datautstyr som stod ubrukt. Skolene
6306 manglet penger til Microsoft-lisenser. Selv med solide skolerabatter,
6307 kostet Microsoft-lisensene gjerne like mye som PC-ene i seg selv over
6308 en periode på
5-
6 år.
</p
>
6310 <p
>Viktigheten av språklig mangfold og pedagogiske programmer var også
6311 viktig for oss. Vi oversatte mange skoleaktuelle programmer til
6312 nynorsk, nordsamisk og bokmål. Dette lenge før andre tok denne
6313 oppgaven seriøst. Allerede etter ett år hadde vi etablert et helt
6314 arsenal av skoleaktuelle programmer på nynorsk, bokmål og
6315 nordsamisk. Vi spredde vår ide om språklig mangfold til de andre frie
6316 prosjekter internasjonalt. Resultatene ser vi i mange land. Det er de
6317 frie programmene som kommer på brukernes morsmål. Det er en av flere
6318 gode grunner til at fri programvare som LibreOffice, VLC, KDE og
6319 Firefox konkurrerer ut godseid programvare mange steder i verden.
</p
>
6321 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6323 <p
>Fordelene er at Skolelinux tilbyr over
100 skoleaktuelle programmer
6324 på de norske språkene, uten ett øre i lisenskostnader. Systemet gir
6325 enormt lave driftskostnader med diskløse arbeidsstasjoner og bærbare
6326 med roaming. Skolelinux krever også mindre av maskinvaren.
</p
>
6328 <p
>Man kan fint kjøre systemet med
512 MB RAM på en bærbar PC sammen
6329 med en nettvideo i nettleseren og en presentasjon med
6330 LibreOffice. Konkurrerende system krever fort
2 GB RAM for å få til
6331 noe tilsvarende uten at det går ufattelig tregt. Skal man gjøre noe

6333 rapportert at de fort har fått
50% flere nye maskiner om de velger

70.000 PC-systemer i skolene i Extremadura i
6340 Spania. Det er slett ikke uvanlig at norske kommuner har
1500-

6349 <p
>Den største ulempen for Skolelinux er motstand mot Linux fra
6350 IT-sjefer i det offentlige. Dette er ledere som holder innlegg som
6351 snytt ut av evangelist-håndboka til Microsoft. Dette gjøres i ett
6352 arbeidsmarked med stor vekst i etterspørselen etter Linux-fagfolk i
6353 privat sektor. Etterspørselen har økt mer enn noe annet tekniske yrke
6354 siste tiåret. Åtte av ti ledere vil ansette Linux-fagfolk i
2012,
6355 rapporterer jobbnettstedet Dice.com på oppdrag av Linux
6356 Foundation.

6358 <p
>Det mangler
16.000 ingeniører og IKT-fagfolk i Norge rapporterte
6359 arbeids- og velferdsetaten NAV. Linux-fagfolk kan velge svært
6360 interessante jobber med alt fra apps på ledende mobilsystem laget med
6361 Linux, sky- tjenester eller web-applikasjoner. De raskest voksende
6362 teknologiselskapene i verden er ute etter Linux-fagfolk. Det være seg
6363 Amazon, Google, Facebook og IBM for å nevne noen. Linux er kritisk
6364 for å sikre veksten i markedet. Det sier seg selv at lønningene og
6365 jobbmulighetene er bedre enn for andre tekniske yrker.
</p

6367 <p
>Skal man lage apps for mobilen, smart-TV-en eller
6368 underholdningssystemet i bilen eller på flyet, er det Linux som
6369 gjelder. Med en slik konkurranse om Linux-kompetansen, kombinert med
6370 motstanden mot Linux hos mange IT-sjefer i offentlig sektor, så
6371 hindrer kommunene rekruttering av flere Linux- fagfolk. Skolene blir
6372 tvunget til å velge dyrere og mindre komplette IT-system. De har
6373 blitt hengende igjen slik IT var på begynnelsen av
2000- tallet. Dette
6374 fordi IT-ledere ikke har tilpasset seg markedet det siste tiåret.

6376 <p
>Når det er sagt, er Skolelinux svært enkelt å lære seg også for de
6377 som ikke kan. Det viser alle lærerne som drifter systemet for
6378 hundrevis og tusenvis av systemer. Det meste er på plass rett ut av
6379 boksen. I tillegg er det solid med dokumentasjon med god hjelp på
6380 nettet. Det er mange kommuner som har ansatt en lærer som først lærte
6381 Skolelinux på sin skole, for så å drifte alle PC-ene i kommunen med
6382 Skolelinux. Det kan fort være snakk om
1000-
3000 datamaskiner på
10-
15
6383 skoler som sentraldriftes med en stilling. Står man ordentlig fast,
6384 kan man også kjøpe profesjonell hjelp fra selskap som støtter
6385 Skolelinux. Det er flere slike selskap i Norge og i utlandet.

6392 finnes ikke tid i livet å undersøke alle valgmulighetene. Derfor er

6449 stiftelsen Åpne kontorprogram på norsk for å oversette og teste den
6450 norske utgaven av OpenOffice.org. Arbeidet har hele tiden vært

>Skolelinux handler i likhet med utdanningssektoren om å dele
6458 kunnskap med andre, og det er dette som er hovedstyrken til
6459 prosjektet. Selv om Skolelinux hovedsaklig er involvert i utvikling
6460 av programvare, er det også et sted der man kan utfolde seg uavhengig
6461 av bakgrunn og ferdigheter.

6485 også utvikle vår egen tilpasset det norske markedet. Det er også
6486 mulig å involvere utdanningssektoren direkte i arbeidet, for eksempel
6487 gjennom studentprosjekter der elevene selv er med å utforme
6488 programvare direkte eller indirekte gjennom aktive bidrag. Dette gjør
6489 ikke bare samarbeidet tettere, men fokuset på standarder og friheten
6490 til å velge sin egen løsning vil kanskje stimulere interessen for
6491 framtidig deltakelse i bransjen. Vi som driver med fri og åpen
6492 programvare ønsker oss ikke rene konsumenter, men tenkende og

>New in the Squeeze version of
6503 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> is the
6504 ability for clients to automatically configure their proxy settings
6505 based on their environment. We want all systems on the client to use
6506 the WPAD based proxy definition fetched from
<tt
>http://wpad/wpad.dat
</tt
>, to
6507 allow sites to control the proxy setting from a central place and make
6508 sure clients do not have hard coded proxy settings. The schools can
6509 change the global proxy setting by editing
6510 <tt
>tjener:/etc/debian-edu/www/wpad.dat
</tt
> and the change propagate
6511 to all Debian Edu clients in the network.
</p
>
6513 <p
>The problem is that some systems do not understand the WPAD system.
6514 In other words, how do one get from a WPAD file like this (this is a
6515 simple one, they can run arbitrary code):

"DIRECT

6525 return
"PROXY webcache:
3128; DIRECT

6532 http_proxy=http://webcache:
3128/
6533 ftp_proxy=http://webcache:
3128/
6534 </pre
></blockquote
>
6536 <p
>To do this conversion I developed a perl script that will execute
6537 the javascript fragment in the WPAD file and return the proxy that
6539 <tt
><a href=
"http://www.debian.org/
">http://www.debian.org/
</a
></tt
>,
6540 and insert this extracted proxy URL in
<tt
>/etc/environment
</tt
> and
6541 <tt
>/etc/apt/apt.conf
</tt
>. The perl script wpad-extract work just
6542 fine in Squeeze, but in Wheezy the library it need to run the
6543 javascript code is
<a href=
"http://bugs.debian.org/
631045">no longer
6544 able to build
</a
> because the C library it depended on is now a C++
6545 library. I hope someone find a solution to that problem before Wheezy
6546 is frozen. An alternative would be for us to rewrite wpad-extract to
6547 use some other javascript library currently working in Wheezy, but no
6548 known alternative is known at the moment.
</p
>
6550 <p
>This automatic proxy system allow the roaming workstation (aka
6551 laptop) setup in Debian Edu/Squeeze to use the proxy when the laptop
6552 is connected to the backbone network in a Debian Edu setup, and to
6553 automatically use any proxy present and announced using the WPAD
6554 feature when it is connected to other networks. And if no proxy is
6555 announced, direct connections will be used instead.
</p
>
6557 <p
>Silently using a proxy announced on the network might be a privacy
6558 or security problem. But those controlling DHCP and DNS on a network
6559 could just as easily set up a transparent proxy, and force all HTTP
6560 and FTP connections to use a proxy anyway, so I consider that
6561 distinction to be academic. If you are afraid of using the wrong
6562 proxy, you should avoid connecting to the network in question in the
6563 first place. In Debian Edu, the proxy setup is updated using dhcp and
6564 ifupdown hooks, to make sure the configuration is updated every time
6565 the network setup changes.
</p
>
6567 <p
>The WPAD system is documented in a
6568 <a href=

6619 var noen annen løsning. «Vandrende arbeidsstasjon» mener jeg ikke
6620 fantes da. Dessuten ville jeg ha siste versjon, da den KDE-versjonen

>Since the Lenny version of
6662 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>, a
6663 feature to save power have been included. It is as simple as it is
6664 practical: Shut down unused clients at night, and turn them on again
6665 in the morning. This is done using the
6666 <a href=
"http://packages.qa.debian.org/s/shutdown-at-night.html
">shutdown-at-night
</a
> Debian package.
</p
>
6668 <p
>To enable this feature on a client, the machine need to be added to
6669 the netgroup shutdown-at-night-hosts. For Debian Edu, this is done in
6670 LDAP, and once this is in place, the machine in question will check
6671 every hour from
16:
00 until
06:
00 to see if the machine is unused, and
6672 shut it down if it is. If the hardware in question is supported by
6674 <a href=
"http://packages.qa.debian.org/n/nvram-wakeup.html
">nvram-wakeup
</a
>
6675 package, the BIOS is told to turn the machine back on around
07:
00 +-
6676 10 minutes. If this isn
't working, one can configure wake-on-lan to
6677 try to turn on the client. The wake-on-lan option is only documented
6678 and not enabled by default in Debian Edu.
</p
>
6680 <p
>It is important to not turn all machines on at once, as this can
6681 blow a fuse if several computers are connected to the same fuse like
6682 the common setup for a classroom. The nvram-wakeup method only work
6683 for machines with a functioning hardware/BIOS clock. I
've seen old
6684 machines where the BIOS battery were dead and the hardware clock were
6685 starting from
0 (or was it
1990?) every boot. If you have one of
6686 those, you have to turn on the computer manually.
</p
>
6688 <p
>The shutdown-at-night package is completely self contained, and can
6689 also be used outside the Debian Edu environment. For those without a
6690 central LDAP server with netgroups, one can instead touch the file
6691 <tt
>/etc/shutdown-at-night/shutdown-at-night
</tt
> to enable it.
6692 Perhaps you too can use it to save some power?

6706 installing new machines, check it out. If you need a software
6707 solution for your school, check it out too. The full announcement is

</p

6711 <p
>I am very happy to report these changes and improvements since
6712 beta2 (there are more, see announcement for full list):
</p
>
6716 <li
>It is now possible to change the pre-configured IP subnet from
6717 10.0.0.0/
8 to something else by using the subnet-change tool after
6718 the installation.
</li
>
6720 <li
>Too full partitions are now automatically extended on the Main
6721 Server, based on the rules specified in /etc/fsautoresizetab.
</li
>
6723 <li
>The CUPS queues are now automatically flushed every night, and all
6724 disabled queues are restarted every hour. This should cut down on
6725 the amount of manual administration needed for printers.
</li
>
6727 <li
>The set of initial users have been changed. Now a personal user
6728 for the local system administrator is created during installation
6729 instead of the previously created localadmin and super-admin users,
6730 and this user is granted administrative privileges using group
6731 membership. This reduces the number of passwords one need to keep
6732 up to date on the system.
</li
>
6736 <p
>The new main server seem to work so well that I am testing it as my
6737 private DNS/LDAP/Kerberos/PXE/LTSP server at home. I will use it look
6738 for issues we could fix to polish Debian Edu even further before the
6739 final Squeeze release is published.
</p
>
6741 <p
>Next weekend the project organise a
6742 <a href=

">developer
6743 gathering

6744 version, and start initial planning for the Wheezy version. Perhaps I
6745 will see you there?

6754 <description><p
>With some computer hardware, one need non-free firmware blobs.
6755 This is the sad fact of todays computers. In the next version of
6756 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> based
6757 on Squeeze, we provide several scripts and modifications to make
6758 firmware blobs easier to handle. The common use case I run into is a
6759 laptop with a wireless network card requiring non-free firmware to
6760 work, but there are other use cases as well.
</p
>
6762 <p
>First and foremost, Debian Edu provide ISO images for DVD and CD
6763 with all firmware packages in the Debian sections main and non-free
6764 included, to ensure debian-installer find and can install all of them
6765 during installation. This take care firmware for network devices used
6766 by the installer when installing from from local media. But for
6767 example multimedia devices are not activated in the installer and are
6768 not taken care of by this.
</p
>
6770 <p
>For non-network devices, we provide the script
6771 <tt
>/usr/share/debian-edu-config/tools/auto-addfirmware
</tt
> which
6772 search through the
<tt
>dmesg
</tt
> output for drivers requesting extra
6773 firmware. The firmware file name is looked up in the Contents-ARCH.gz
6774 file available in the package repository, and the packages providing
6775 the requested firmware file(s) is installed. I have proposed to do
6776 something similar in debian-installer (BTS report
6777 <a href=
"http://bugs.debian.org/
655507">#
655507</a
>), to allow PXE
6778 installs of Debian to handle firmware installation better. Run the
6779 script as root from the command line to fetch and install the needed
6780 firmware packages.
</p
>
6782 <p
>Debian Edu provide PXE installation of Debian out of the box, and
6783 because some machines need firmware to get their network cards
6784 working, the installation initrd some times need extra firmware
6785 included to be able to install at all. To fill the PXE installation
6786 initrd with extra firmware, the
6787 <tt
>/usr/share/debian-edu-config/tools/pxe-addfirmware
</tt
> script is
6788 provided. Again, just run it as root on the command line to fill the
6789 PXE initrd with firmware packages.
</p
>
6791 <p
>Last, some LTSP clients might also need firmware to get their
6792 network cards working. For this,
6793 <tt
>/usr/share/debian-edu-config/tools/ltsp-addfirmware
</tt
> is
6794 provided to update the LTSP initrd with firmware blobs. It is used
6795 the same way as the other firmware related tools.
</p
>
6797 <p
>At the moment, we do not run any of these during installation. We
6798 do not know if this is acceptable for the local administrator to use
6799 non-free software, and it is their choice.

6818 språket melde seg til dyst. Det er mangel på nordsamiske oversettere
6819 av fri programvare. Hvis noen starter raskt, så bør en rekke å

>The next version of
<a href=
"http://www.skolelinux.org/
">Debian Edu
6858 / Skolelinux
</a
> will include a new tool
6859 <tt
>sitesummary2ldapdhcp
</tt
>, which can be used to quickly set up all
6860 the computers in a school without much manual labour. Here is a short
6861 summary on how to use it to set up a new school.
</p
>
6863 <p
>First, install a combined Main Server and Thin Client Server as the
6864 central server in the network. Next, PXE boot all the client machines
6865 as thin clients and wait
5 minutes after the last client booted to
6866 allow the clients to report their existence to the central server. When
6867 this is done, log on to the central server and run
6868 <tt
>sitesummary2ldapdhcp -a
</tt
> in the
<tt
>konsole
</tt
> to use the
6869 collected information to generate system objects in LDAP. The output
6870 will look similar to this:
</p
>
6872 <p
><blockquote
><pre
>

6882 </pre
></blockquote
></p
>
6884 <p
>After providing the LDAP administrative password (the same as the
6885 root password set during installation), the LDAP database will be
6886 populated with system objects for each PXE booted machine with
6887 automatically generated names. The final step to set up the school is
6888 then to log into
<a href=
"https://oss.gonicus.de/labs/gosa/
">GOsa
</a
>,
6889 the web based user, group and system administration system to change
6890 system names, add systems to the correct host groups and finally
6891 enable DHCP and DNS for the systems. All clients that should be used
6892 as diskless workstations should be added to the workstation-hosts
6893 group. After this is done, all computers can be booted again via PXE
6894 and get their assigned names and group based configuration
6895 automatically.
</p

6897 <p
>We plan to release beta3 with the updated version of this feature
6898 enabled this weekend. You might want to give it a try.

6901 hosts, one need to add the option -a. I forgot to mention this in my

>I serien med intervjuer av folk i

">Skolelinux
</a

6913 lyktes med å få tak i en skolemann som ikke er aktiv med utviklingen,
6914 men likevel har vært med nesten siden starten av prosjektet. Jeg
6915 ønsker derfor velkommen til Paul Reidar Løsnesløkken, en mann med
6916 mange års erfaring i bruk av Skolelinux.
</p

6918 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p

6920 <p
>Jeg driftet tidligere IKT løsningen for skolene i
6921 <a href=
"http://www.nord-odal.kommune.no/
">Nord-Odal
</a
>. I dag er jeg
6922 IKT-konsulent for hele kommunen og samarbeider med
6923 <a href=
"http://www.hedmarken-ikt.no/
">Hedmark-IKT
</a
> for best mulig
6924 tjenester til kommunen. Jeg har bakgrunn som elektronikkreparatør og
6925 grunnskolelærer og har tatt en del fag innen IKT, i hovedsak
6926 driftsfag. IKT i Nord-Odal kommune blir i dag driftet av Hedmark IKT
6927 som er et samarbeid mellom Løten, Stange, Grue, Hamar, Kongsvinger og
6928 Nord-Odal. Jeg er fortsatt
"IKT-personen
" på skolene i kommunen og
6929 følger opp og gjør enkelte mindre endringer der.
</p
>
6931 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
6933 <p
>Kommunen satset på Skolelinux i
2004. Jeg var ikke med i
6934 beslutningsprosessen den gang, men ble likevel med fra starten når
6935 dette ble levert.
</p
>
6937 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6939 <p
>Fordelene med Skolelinux er rask oppstart, sentral drift av
6940 klientene, klienter som jobber raskt og effektivt, bedre
6941 funksjonalitet på eldre utstyr og en ganske god programpakke med fri
6942 programvare som følger med. Løsningen med halvtykke klienter gjør at
6943 prosessering skjer lokalt med alltid ferske maskiner.
</p
>
6945 <p
>Skolelinux kan fungere godt på gammelt utstyr, men det er klart at
6946 utstyr også blir for gammelt selv for Skolelinux. I forbindelese med
6947 at vi nylig fikk nye servere og ny installasjon kastet jeg ut ca
60
6948 klienter som fortsatt var i drift etter at de var kjøpt godt brukt i
6949 2004. Noe var rundt
15 år gammelt, men var fortsatt i bruk. Noen
6950 klaget på at det nå gikk veldig tregt på en del pedagogiske nettsider
6951 med flash o.l. Det er fullt forståelig.
</p
>
6953 <p
>Jeg fikk nylig et spørsmål fra ungdomsskolens rektor om jeg kunne
6954 legge inn
<a href=
"http://freemind.sourceforge.net/
">FreeMind
</a
>, et
6955 tankekartprogram , på skolens elev-Windowsmaskiner. Lærerne hadde
6956 vært på kurs og ville ta dette i bruk. Skolen har ca halvparten av
6957 elevmaskinene på bærbare Windowsmaskiner. Da kunne jeg fortelle at
6958 dette programmet allerede lå inne på den nye Skolelinuxløsningen
6959 som nettopp var satt i drift, klart til bruk.
</p
>
6961 <p
>Vi har de bærbare maskinene på ungdomsskolen i domene med
6962 Skolelinux. Dette fungerer også meget bra nå. Elevene får opp en
6963 midlertidig windowsprofil når de logger på. Denne profilen slettes
6964 etter at de logger av, noe som medfører rene profiler hver gang de
6965 starter opp en maskin. De må lagre i sin Skolelinprofil, noe som
6966 medfører at de får tak i sine filer uavhengig av om de starter en
6967 Windowsmaskin eller en Skolelinuxklient. Det er mye mindre trafikk i
6968 det trådløse nettet etter at ikke hele profiler blir lastet opp til de
6969 enkelte Windowsmaskinene og tilbake når man avslutter. Jeg vet ikke om
6970 dette er standardoppsett i Skolelinux, men slik er vårt oppsett
6973 <p
>Vi har i flere år satt opp vår løsning slik at skriverkøer slettes
6974 og skrivere startes hver natt. Hyggelig å høre at dette nå skal bli
6975 en standard i Skolelinuxløsningen. Dette har vært en god hjelp for
6978 <p
>Elevene er lite opptatt av om de jobber på en Skolelinux eller en
6979 Windowsmaskin bare de har de programmene de trenger og at det virker
6980 når det skal brukes. Vi kjører mest mulig de samme programmene på
6981 Windows som i Skolelinux, som f.eks Audacity og LibreOffice.
</p
>
6983 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6985 <p
>Lærere bruker hos oss Windows. Dette fordi de da selv har mer
6986 kontroll over sin maskin, kan bruke den overalt, og kan legge inn
6987 programmer selv når de trenger noe i forhold til kurs o.l de er
6988 på. Jeg tror lærernes selvstendighet her gjør dem tryggere på IKT-bruk
6989 generelt. Det at de av og til får opp advarsler og lignende gjør også
6990 at de må tenke igjennom og spørre om ting rundt datasikkerhet.
</p
>
6992 <p
>Det er en del programmer vi bruker som ikke finnes for Linux. Mest
6993 brukt er nok Photostory3 som brukes i mange sammenhenger, særlig på
6994 ungdomsskolen, bl.a. til å lage herbarier (plantesamling) . Dette
6995 finnes gratis for Windows, men er ikke fri programvare. Vi er opptatt
6996 av at programmer elevene bruker på skolen også kan brukes gratis
6997 hjemme. Det er også en del programmer som brukes til spesielle elever
6998 som bare går i Windows. Det er viktig med fokus på funksjoner og ikke
6999 på hvilket OS man bruker.
</p

7001 <p
>For oss er det kombinasjonen mellom Skolelinux og Windows som gir
7002 oss en god og hel løsning. Skolelinux er best der de er gode.

7006 <p
>Selv er det LibreOffice jeg bruker til daglig. Jeg bruker selv en
7007 Windowsmaskin. Jeg har benyttet en del fri programvare i forbindelse
7008 med sjekking av trafikk i nettverk, slik som Wireshark, men dette er
7009 jo ikke aktuelt for skolene. Jeg er generelt glad i programmer som
7010 fungerer på både Linux og Windows og gjerne MAC.

7015 <p
>Det er viktig at det benyttes programmer som elevene også kan ta i

"fri
7018 programvare
". For skolene tror jeg
"gratis
" og
"funksjonelt
" er bedre
7019 begreper enn
"fri
" i forhold til programmer. De fleste skiller nok
7020 ikke mellom
"fri
" og
"gratis
". Det er nå svært mange elever som
7021 benytter OpenOffice eller LibreOffice som sin primære kontorpakke

>During christmas, I have been working getting the next version of
7078 <a href=
"http://www.skolelinux.org/

</a

7079 for release. The initial problem I looked at was particularly
7080 interesting.
</p

7082 <P
>The installer would hang at the end when it was doing it
7083 post-installation configuration, and whatevery I did to try to find
7084 the cause and fix it always worked while I tested it, but never when I
7085 integrated it into the installer and ran the installation from
7086 scratch. I would try to restart processes, close file descriptors,
7087 remove or create files, and the installer would always unblock and
7088 wrap up its tasks.
</p
>
7090 <p
>Eventually the cause was found. The kernel was simply running out
7091 of entropy, causing the Kerberos setup to hang waiting for more.
7092 Pressing keys was adding entropy to the kernel, and thus all my tries
7093 to fix the problem worked not because what I was typing to fix it, but
7094 because I was typing.
</P
>
7096 <p
>The fix I implemented was to add a background process looking at
7097 the level of entropy in the kernel (by checking
7098 /proc/sys/kernel/random/entropy_avail), and if it was too small, the
7099 installer will flush the kernel file buffers and do
'find /
' to
7100 generate some disk IO. Disk IO generate entropy in the kernel, and is
7101 one of the few things that can be initated from within the system to
7102 generate entropy.

>Etter en lang pause er det klart for neste mann ut i min serie med
7119 <a href=

">Skolelinux
</a

7121 Denne gangen har jeg besøk av et avtroppende styremedlem i
7122 <a href=

">FRISK
</a

7123 som har vært aktiv i Linux-miljøet i Bergen siden
90-tallet.
</p

7125 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
7127 <p
>Jeg heter Peter Hansteen, og jobber til daglig som seniorkonsulent
7128 i EDB ErgoGroup i Bergen. I praksis betyr det systemadministrasjon på
7129 Unix (primært Solaris, men en viss komponent av Linux). Men Solaris
7130 er for meg et relativt nytt bekjentskap, hovedplattformen min har
7131 generelt vært OpenBSD og til dels FreeBSD.
</p
>
7133 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
7135 <p
>Jeg husker ikke helt alle detaljene mer ;) - men jeg tror det var
7136 gjennom news-gruppen no.it.os.unix.linux.diverse, efn-listen og
7137 etterhvert også BLUG-miljøet her i Bergen. Vi hadde et par
7138 Skolelinux-sentrerte BLUG-møter for noen år siden, og det har vært et
7139 par Skolelinux-utviklersamlinger her.
</p
>
7141 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7143 <p
>Jeg bruker dessverre ikke Skolelinux daglig. Men slik jeg kjenner
7144 prosjektet har det vært i stand til å ta opp i seg det beste av fri
7145 programvare i mange kategorier, så fra et sysadmin-perspektiv ser det
7146 ut som en svært behagelig sak. For brukerne er det vel både en fordel
7147 og en ulempe at det ikke er Windows. Men vi håper at fordelene med et
7148 fritt system etterhvert vil bli åpenbare for både elever, lærekrefter
7149 og foreldre.
</p
>
7151 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7153 <p
>Vel, ulempen er vel først og fremst at andre aktører med mer
7154 kapitalmuskel har klart å etablere seg som det både lærere og foreldre
7155 føler seg trygge på, selv om det etter mitt hode ikke er noen grunn
7156 til å være spesielt trygg på de kommersielle alternativene.
</p
>
7158 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
7160 <p
>Når jeg får bestemme helt selv, bruker jeg kun fri programvare. Da
7161 helst med vekt på ting som kjører greit på OpenBSD. Hjemme er det
7162 OpenBSD, Ubuntu eller FreeBSD vi bruker. På skrivebordet er det en
7163 avveining mellom Gnome, KDE eller hva-det-nå-heter som er
7164 standardvalget i Ubuntu, ellers er det de kjente tingene som
7165 LibreOffice, Emacs, mplayer. På server er det selvfølgelig Apache,
7166 for overvåking både OpenNMS og Nagios (det bare ble sånn, og
7167 forskjellige siter). Jeg skriver til tider om slikt jeg holder på med
7169 <a href=
"http://bsdly.blogspot.com
">http://bsdly.blogspot.com
</a
>.
</p
>
7171 <p
>Men vi må nevne at selv vi har en Microsoft-ting som vi slår på når
7172 vi av en eller annen grunn må. Det betyr igjen vanligvis når en
7173 mobiltelefon eller en annen lukket elektronisk dings krever kontakt
7174 via en slik for å få oppdateringene sine.
</p
>
7176 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
7177 skoler til å ta i bruk fri programvare?
</strong
></p
>
7179 <p
>Hadde vi hatt det rette svaret på det spørsmålet, så hadde vi
7180 gjerne hatt Skolelinux som førstevalg på alle skoler ;)
</p
>
7182 <p
>Men jeg tror vi må legge vekt på flere forskjellige ting. En helt
7183 sentral sak er å fokusere på fri programvare og åpne standarder som de
7184 demokratiske verdiene de faktisk er. Det har kanskje kommet litt for
7185 mye i bakgrunnen i forhold til strevet etter å lage det mest mulig
7186 'brukervennlige
' systemet. Det er en tung vei å gå, så det er
7187 forståelig at freenix-aktivister heller velger å skrive kode og annet
7188 som er mer lystbetont. Mer praktisk tror jeg vi må gjøre i alle fall
7189 to ting: For det første sørge for å fortsette med å levere det best
7190 mulige frie produktet, slik at det er lett å både komme i gang og
7191 holde systemene i daglig drift, og for det andre
2) spore opp mulige
7192 aktivister der de finnes, via lokale brukergrupper, sosiale medier
7193 eller annet og sørge for at de fortsetter å være aktive. Mer og
7194 mindre uformelle treff kan være nyttig i tillegg til de mer
7195 organiserte møtene med foredrag, konferanser og utviklersamlinger.

7213 driftsselskap for Grue, Hamar, Kongsvinger, Løten, Nord-Odal og Stange

><strong

</strong
></p
>
7220 <p
>Jobbet i IBM fra
2000, og da spesielt med Linux. Dette var da et av
7221 de mest tydelige linux prosjektene i Norge, og her ønsket jeg å
7222 bidra. Var aktivt med i prosjektet i
4-
5 år.
</p
>
7224 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7226 <p
>Fordelene slik jeg ser det er den sentraliserte driftmodellen, og
7227 alle de vel gjennomtenkte løsningene som er inkludert i denne
7228 løsningen. Samtidig er det basert på en stabil, og godt kjent
7229 plattform. Dette vil si at man har en løsning som skal være mye
7230 tilgjengelig, og hvor det er relativt enkelt å få tak i personer som
7231 kan mye om den grunnleggende plattformen.
</p
>
7233 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7235 <p
>De største utfordringene med en løsningen er at den er intensiv på f.eks
7236 nettverk. I seg selv ikke et problem for en enkelt skole, men skal løsningen
7237 kjøres i større skala, med sentraliserte servere, så gir dette noen
7238 utfordringer.
</p
>
7240 <p
>Utifra hva jeg har sett på større installasjoner så er det ikke så
7241 enkelt å skjønne, hva som bør gjøres for at den skal skaleres opp, og
7242 da ta godt vare på alle sider av dette, ikke bare mer server å fordele
7243 last/trykk, men hvordan også beholde robustheten og fleksibiliteten i
7244 løsningen.
</p
>
7246 <p
>En annen utfordring er at stadig flere produkter som skal brukes i
7247 skoleløsningen ikke er laget til å kunne brukes i en
7248 skolelinuxløsning. Det blir derfor fort mye skreddersøm i de
7249 forskjellige installasjonene, for å få diverse pedagogiske programmer,
7250 webløsninger, smartboards, m.m. til å fungere. Man er også en for
7251 liten kundebase til at leverandørene ønsker å gjøre noe med
7252 utfordringen. Problemet overlates til oss.
</p
>
7254 <p
>Det er også en kontinuerlig utfordring rundt problemet med å holde
7255 programvare på stabile versjoner, kontra å få ny funksjonalitet. Dette
7256 er jo en konflikt mellom oss som ønsker å drifte en stabil, og
7257 kostnadseffektiv løsning, mot sluttbrukerne som ønsker seg funksjoner
7258 det er vant med fra andre løsninger, eller som de må ha for at et
7259 eller annet nytt produkt skal fungere i løsningen. Dette er en
7260 utfordring også for andre plattformer.
</p
>
7262 <p
>En siste utfordring som ikke har noe med løsningen å gjøre, men med
7263 det omkringliggende miljøet denne skal kjøre i, er at de enhetene som
7264 skal drifte dataløsninger for kommuner og fylkeskommuner begynner å
7265 profesjonaliseres, og er da avhengig av å ha standard løsninger for å
7266 drifte store brukermasser. MS er selvsagt klar over dette, og har jo
7267 nå flere områder de begynner å bli veldig dominerende på. Den største,
7268 og mest problematiske er katalogtjenesten. Man får snart ikke tak i
7269 større løsninger som ikke krever en AD. Når man da har store enheter
7270 som drifter både kommunalt ansatte og skoler, så vil det være et
7271 stordriftargument å standardisere på en katalog tjeneste, og da har
7272 man ikke noe valg. Her er alle slike driftsenheter for små til å få
7273 gjort om på dette. Her burde konkurransemyndighetene kommet på
7274 banen. Men konkurransetilsynet i USA griper sjeldent (og ikke før det
7275 har gått veldig lang tid) inn i monopolsituasjoner så lenge
7276 monopolisten er et amerikansk firma, så da har vel ikke andre
7277 myndigheter så mye de skulle ha sagt....

7281 <p
>Privat kjører jeg Debian på alle mine datamaskiner. Det gjør jeg
7282 også på min jobbmaskin. Vi har også
15-
20 linux servere av typene
7283 SuSE, Debian, Redhat, CentOS m.m. Jeg bruker derfor mye fri
7284 programvare. Av enkelt programmer kan sikkert masse nevnes. Hvis vi
7285 skal begrense oss til daglig, så må jeg si: OpenOffice, Firefox,
7286 Kontact, Kopete, Amarok,
7287 <a href=
"http://gramps-project.org/
">Gramps
</a

7288 rsync, backuppc m.m.

7290 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
7291 skoler til å ta i bruk fri programvare?
</strong
></p
>
7293 <p
>Det er et godt spørsmål, som jeg har lurt på selv.
</p
>
7295 <p
>Argumentene som ofte har vært brukt om at ting koster mindre holder
7296 ikke mål når man ser på hva som faktisk koster penger. Det er de
7297 ansatte som er en kostnadsdriver. Det vil si at hvis man har et system
7298 som den ansatte kan, så vil en kostnad på dette systemet kunne
7299 forsvares ganske mye ved at den ansatte gjør dette raskere og
7300 effektivt. Også uten å måtte eventuelt leie inn folk.
</p
>
7302 <p
>Jeg syns det er viktigere å fokusere på prinsippet med å velge fri
7303 programvare, men det er også et felt hvor man fort møter lite
7304 forståelse blant de ansatte i skolen.
</p
>
7306 <p
>Her må nok strategien fortsette å være at de sentrale myndighetene
7307 må sende tydelige signaler for hva de ønsker at offentlige enheter
7308 skal gjøre. Det var mye positivt på gang ang. dette for et par år
7309 siden. Både med eNorge og eKommune planene, men dette syns jeg har
7310 stoppet opp. En del av dette kan jo kanskje være usikkerheten som
7311 etter hvert har blitt, når man har sett kompleksiteten i de
7312 prosjektene som har blitt igangsatt. Det har også blitt noe usikkerhet
7313 i markedet ref. Sun, Oracle, Novell, Microsoft m.m. Samtidig har jo
7314 også de proprietære programleverandørene sørget for å endre sine
7315 lisenser slik at man uansett ikke slipper unna kostnaden til deres
7316 produkter, selv om man skulle velge alternativer. Da er det økonomiske
7317 argumentet, som jeg nevnte tidligere, spilt ganske godt ut over
7318 sidelinjen.

7341 <p
>Hmm, det er lenge siden, så det er nesten så jeg ikke husker. Jeg
7342 hadde vel hørt om prosjektet i media før en gjeng i Trondheim startet
7343 opp SPIST, Skolelinux-prosjektet i Sør-Trøndelag, hvor vi hjalp noen
7344 skoler i nærområdet med å installere Skolelinux og finne brukt
7345 IT-utstyr til disse. Det var moro å gjøre noe praktisk for å spre
7346 Skolelinux, og å se hvor fort gjort det var å sette opp utrangerte
7347 klientmaskiner og få disse opp som tynnklienter på helt nye datasaler
7348 på skolene, kun med kostnaden til servere.

7352 <p
>Det er et system spesielt skreddersydd for drift av et stort antall
7353 klienter mot servere, og da spesielt i henhold til skolers behov. Det
7354 er enkelt og billig å installere og drifte, og det trenger ikke ny
7355 maskinvare for god ytelse.

7359 <p
>Hardwarestøtten kunne vært bedre og i enda større grad
7360 installerbart rett ut av boksen. Distribusjonen har til tider hatt
7361 litt gammel programvare pga. at den følger Debian sine utgivelser.
7362 Kanskje man skulle vurdert en versjon basert på Ubuntu eller andre
7363 distribusjoner i tillegg?

7369 Chromium, Pidgin, Digikam, OpenOffice, Wireshark, git og irssi.
7370 Telefonen min er en Android, og der bruker jeg programmene K-

7371 OI Shopping list, Shuffle, ZXing, OI Notepad og ADW Desktop. På jobb
7372 bruker jeg JBoss, Eclipse, uCLinux for Blackfin, RCF-CPP, Qt, Maven,

7378 <p
>En bør fokusere på totalkostnader inkludert driftsbehov,
7379 fleksibilitet, åpenhet og ikke låsing til en leverandør framfor sparte
7380 lisenskostnader, samt programvarens kvalitet og fortrinn, og at den
7381 fritt kan brukes på et ubegrenset antall PC-er, også hjemme hos
7382 elevene. En bør også forbedre den fri programvaren ved testing,
7383 bugrapportering og kodebidrag om man kan, og ikke anbefale programvare
7384 uten at man har forsikret seg at den har tilstrekkelig kvalitet,
7385 ellers kan man lett oppnå det motsatte. Tror en bør selge inn
7386 konseptet til fylkes-/statsnivå, kanskje med bidrag til
7387 utviklingsarbeid fra disse som alle landets skoler kan få glede

>Mine bloggposter om Linux i skolene i Norge førte til at inspektør
7398 og ildsjel på Harestad skole tok kontakt og fortalte at de bruker
7399 Linux på sin skole, og lurte på om de kunne bidra til å gjøre
7400 fordelene kjent. Riktig nok bruker de ikke
7401 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
> på denne skolen,
7402 men jeg synes dette er en god anledning til å gjøre flere fasetter
7403 rundt Linux-økosystemet kjent, og tok et lite intervju.
</p

7405 <p

7407 <p
>Mitt navn er Odin Hetland Nøsen og er en
70-modell. Jeg er bosatt i
7408 Stavanger og jobber nå på
9. året som undervisninginspektør på
7409 Harestad skole i Randaberg kommune (nabokommune til Stavanger).
</p

7411 <p
><strong

</strong
></p
>
7413 <p
>I
2002 begynte daværende IKT-ansvarlige og jeg et arbeid på skolen
7414 med å gå over fra Win98 til... noe annet. Vi testet en rekke
7415 forskjellige løsninger, deriblant Skolelinux, men endte opp med
7416 RedHat. Skolelinux var den gang ikke modent for det vi ville ha. Jeg
7417 har siden fulgt jevnlig med på hva skolelinux holder på med, men har
7418 hele tiden vært bedre fornøyd med vår egen
"standardiserte
" løsning på
7419 RedHat/CentOS og Fedora. Vi snuser for tiden på Ubuntu som løsning på
7420 klientsiden.
</p
>
7422 <p
>I dag har vi på skolen vår en større linux-løsning med
400 klienter
7423 som kjører en blanding av LTSP (tynnklient) og DRBL (tykk klient uten
7424 harddisk) med en masse tjenere på serverrommet. Vi drifter hele
7425 sulamitten selv med webtjener, eposttjener, webmail, filtjenere,
7426 virtuelle tjenere osv. Og IT-ansvarlig har en
80% stilling som
7427 IT-ansvarlig - og så er han KoH-lærer i de resterende
20% :-)
</p
>
7429 <p
>Du kan få en ide om hva vi holder på med om du går inn på
7430 <a href=
"http://www.gnuskole.no/
">http://www.gnuskole.no/
</a
>.
</p
>
7432 <p
>For å ta brodden av frykten for at ildsjeler gjør skolen sårbar om
7433 ildsjelene falle fra, har jeg forsikret kommunen og skolesjefen i
7434 Randaberg om at det finnes godt kommersielle tjenester vi kan benytte
7435 oss av - om det skulle bli nødvendig. Vi er tre stykker i kommunen som
7436 nå har
<strong
>god
</strong
> linux-kompetanse ift. å drifte et større
7437 system. IT-avdelingen i kommunen vil ikke ta på oss med ildtang -
7438 selv om vi nok har større IT-kompetanse mot linux enn det de selv har
7439 mot windows (de kjøper en
<strong
>masse
</strong
> konsulenttjenester
7440 fra ErgoGroup).
</p
>
7442 <p
>I kvantitet er Harestad og Grødem skole tilsammen et større
7443 IT-system enn resten av Randaberg kommune + Kvitsøy og Rennesøy, som
7444 kommunen også har driftsansvar for. Vi har som sagt rundt
800
7445 maskiner, mens kommunen med sitt driftsansvar har ansvar for rundt
500
7446 maskiner. Det er selvfølgelig litt forskjell i hvor kritiske
7447 tjenestene våre er, men det gir allikevel et litt rart bilde når
7448 IT-avdelingen overhode ikke er interessert i å snakke med oss om
7449 hvordan vi gjør ting :-)
</p
>
7451 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7453 <p
>Fra linux-perspektivet (ikke bare Skolelinux) er det en fordel av
7454 systemet er basert på fri programvare - og dermed fritt i ordets mange
7455 betydninger. Det er alt vi trenger: stabilt, relativt enkelt å drifte
7456 (tross alt - et større windowssystem er ikke enkelt å holde live det
7457 heller), rimelig i innkjøp og drift, og sist, men ikke minst, det er
7458 moderne for sluttbruker! Linux, i sine mange varianter,
7459 <strong
>ser
</strong
> nytt ut, fordi det hele tiden blir
7460 oppdatert. Derfor lever systemet opp til hvordan elever forventer at
7461 et moderne GUI skal være (i motsetning til WinXP :-).
</p
>
7463 <p
>Vi var veldig pragmatiske da vi begynte med linux i skolen. Det var
7464 billig, det fungerte og kunne bruke alle de gamle windows-maskinene
7465 som
"nye
" tynne klienter. I dag er vi mer bevisste fri
7466 programvare-tilhengere. Vi har oppdaget hva det er - og vi liker
7469 <p
>En av de
<strong
>store
</strong
> fordelene med fri programvare er at
7470 vi kan installere tjenester vi ønsker å tilby brukerne våre - uten å
7471 måtte tenke på om vi har råd til lisensene (fordi det er ingen). Alt
7472 vi setter i produksjon er ut i fra brukernes behov og vår kapasitet
7473 til å drifte dem. Vi skreddersyr tjenestene etter behovet og dermed
7474 trenger vi ikke ende opp med å kjøpe en pakke der vi egentlig bare var
7475 interessert i en liten del av den.
</p
>
7477 <p
>Bruk av linux frigjør ikke økonomiske midler, fordi midlene til IKT
7478 i skole er for få i utgangspunktet - men vi får så
7479 <strong
>mye
</strong
> mer igjen for dem når vi bruker en linux-løsning
7480 fremfor en windows-løsning. I praksis ser vi at vi måtte ut med det
7481 dobbelte på budsjettet vårt om vi skulle hatt en tilsvarende
7482 windows-løsning, som det vi i dag drifter med linux.
</p

7484 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7486 <p
>Ikke all pedagogisk programvare er tilgjengelig. Det er en del
7487 programvare i skolen som er laget med utviklerverktøy som bare virker
7488 i windows, f.eks. Drillpro, LingDys/LingWrite. Det er også
7489 "programmer
" som bare virker om du har tilgang til Microsoft Office,
7490 f.eks. AskiRaski.
</p
>
7492 <p
>Vi sliter også litt med at video-codecer ikke alltid er like lett å
7493 få opp å gå på klientene. Det er alltid en eller annen videosnutt fra
7494 nrk.no som ikke er så samarbeidsvillig, uansett mediaplayer.
</p
>
7496 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
7498 <p
>Alt :-) På skolen bruker vi det som finnes og som er nyttig. Det vi
7499 bruker mest er Firefox (jobber med Chrome, fordi det er
7500 <strong
>mye
</strong
> raskere med Flash enn Firefox), OpenOffice (skal
7501 over til LibreOffice), GIMP osv. Standardpakken av
7502 sluttbrukerprogrammer.
</p
>
7504 <p
>På tjenernivå bruker vi OpenWebMail (skal over til Zimbra), Exim
7507 <p
>Personlig bruker jeg de fleste programmer over flere plattformer,
7508 men jeg har lagt meg til en vane å prioritere bruken av fri
7509 programvare også i Windows
7 og OSX.
</p
>
7511 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
7512 skoler til å ta i bruk fri programvare?
</strong
></p
>
7514 <p
>Jeg er langt i fra sikker. For det første handler det mye om at
7515 IKT-avdelingen i kommunen ofte er de som styrer hva som er IKT på
7516 skolene - og de liker å bruke avtalene med Microsoft, som de garantert
7517 har fra før. Dessuten - Select
6-avtalen til skolene gjør Microsoft
7518 skvettbillig.
</p
>
7520 <p
>Vi la vekt på effektiv drift av systemet - og at vi kunne øke
7521 antall maskiner uten å måtte øke budsjett for utstyr eller personell
7522 særlig mye, enn om vi hadde gått for en Microsoft-løsning. I praksis
7523 ser vi at en ren linux-installasjon driftes til halve prisen av en
7524 Microsoft-løsning.
</p
>
7526 <p
>Vi har i praksis også sett at det lærerne (og elevene) liker er at
7527 vi tilbyr
<strong
>veldig
</strong
> mange tjenester som ikke er så
7528 vanlige i en Microsoft-løsning. Det er ikke så vanlig at
7529 <strong
>elevene
</strong
> også har epost, hjemmekontor osv. Det har vi
7530 også brukt som et vellykket argument mot Microsoft.
</p
>
7532 <p
>Den beste måten er selvfølgelig at noen bare bestemmer
7533 det. Problemet er å få dem som har makt til å bestemme det til faktisk
7534 å gjøre det ;-)

7555 <p
>Det viktigste for meg som IKT veileder er å få fundamentert den
7556 5. basisferdigheten, digital kompetanse ved skolen min på en god måte
7557 slik at hele skolesamfunnet tar i bruk IKT i alle fag. Dette arbeidet
7558 gjøres i nært samarbeid med skolens ledelse.

7576 for oss at vi har digitale systemer som gjør at vi kan følge
7577 læreplanen i alle fag. Det syns jeg at vi kan gjøre gjennom

7582 <p

7584 ulempe at ikke alle på denne avdelingen nødvendigvis er god på
7587 <p

7624 på
6 år. Jobber i Oslo som Global Sales Executive hos Varnish Software
7625 og til daglig har jeg kontakt med kunder fra hele verden. Min
7626 forkjærlighet for fri programvare har gjort at jeg har nå flere års
7627 erfaring med salg av slike løsninger (bl.a. fra Redpill Linpro og
7628 Freecode) og mye innsikt og kunnskap om det globale IT-markedet.
7629 Ellers er jeg involvert i flere prosjekter bl.a. er jeg Ubuntu
7630 Community medlem, kontaktpersonen for Ubuntu Norge og driveren av
7631 SpreadUbuntu marketing prosjektet og nå fersk styremedlem i FRISK. Jeg
7632 har brukt GNU/Linux siden

7636 <p
>Som Debian bruker siden slutten av
90-tallet var det uunngåelig å
7637 ikke komme bort i Skolelinux. Dette var vel i slutten av
2001 når jeg
7638 var student ved UiO. Flere år senere fikk jeg lastet og testet Venus
7639 (Skolelinux
1.0) på release dagen.

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

7643 <p
>Fri programvare bygges sten for sten i det åpne, slik at koden og
7644 prosessen den lages på kan gjennomskues av andre enn de som har laget
7645 det. Det er et vitenskapelig og gjennomsiktig måte å lage programvare
7648 <p
>Skoler i vårt samfunn skal være steder hvor vitenskapelig kunnskap
7649 deles til alle. I dag har vi ikke et vitenskapelig tilnærming til
7650 hvordan programvaren som brukes på skolen lages. Skolelinux bringer
7651 inn at slik tilnærming i skoleverkets klasserom, siden
7652 operativsystemet er en åpent platform som gir skolene muligheten til å
7653 dra nytte av programvare som er laget av tusenvis av mennesker verden
7654 rundt og som gir elevene så vel som lærerne muligheten til å bruke,
7655 dele, forandre og forbedre OSet sitt uten begrensninger. I den
7656 forbindelsen representerer Skolelinux også konkrete resultater utfra
7657 samhandling på tvers av grenser.
</p
>
7659 <p
>Når det gjelder de tekniske fordelene av Skolelinux er jeg sikker
7660 på at andre enn meg har allerede beskrevet disse bedre enn det jeg
7661 kan. Men jeg kan likevel tilføye noe: Skolelinux som sådan er en
7662 community-drevet operativsystemplatform. Som i ethvert
7663 community-prosjekt har alle Skolelinux brukere muligheten til å
7664 påvirke retning av prosjektet og resultatet som gjenspeiles i
7665 programvaren. Dette kommer sjeldent frem og jeg mener at det er noe
7666 som burde fokuseres mer på.

7670 <p

</p

7673 <li
>Mangel på kompetanse

7674 <li
>Mangel av administrative verktøy som kunne hjelpe lokale IT
7675 avdelinger å bruke Skolelinux til mer enn bare en tjener for
7676 terminalklienter. Et eksempel: Zentyal sin web-dashboard.
</li
>
7679 <p
>Bedre og mer intuitive administrative verktøy kunne løst deler av
7680 problemet, men det er unektelig at ved bruk av Skolelinux må
7681 IT-personalet vite hva de gjør for å få ting gjort riktig, eller i det
7682 hele tatt. Med andre platformer er kompetansen enklere tilgjengelig og
7683 løsningene kan fungere på en tilfredstillende, om ikke riktig

7699 opplysning, kunnskap og kompetanse.

7720 Vi ser på en åpen løsning som integrerer eksisterende lukkete

7722 en plattform som de kan tilpasse utfra behov.

7726 <p
>Skolelinux har jeg møtt ved flere anledninger opp gjennom åra, både gjennom
7727 entusiastiske skolelinuxbrukere og skeptiske
"forståsegpåere

7729 <p
>Jeg husker en leverandør av et stort OS for noen år siden mente at
7730 Skolelinux var kun for hackere og nerder og at ingen seriøse skoler
7731 kunne ta dette i bruk. Heldigvis er kunnskapen større nå og
7732 skikkelige
"IT-folk
" søker alltid å utvide sin kunnskap.

7736 <p
>Ja det er mange fordeler. Uavhengighet, stabilitet, åpenhet, standarder

7742 <p
>Det største hinderet er det vi opplever på andre områder rundt
7743 fri programvare, nemlig kunnskap. For mange er det trygt å velge det vi
7744 alltid har valgt. Fordi leverandørene rundt oss sitter på den kunnskapen og
7745 de vi støtter oss på har den samme. Hvis vi klarer å riste løs litt og
7746 glemme gamle kriger mellom operativsystemer og leverandører, men sette ned
7747 hva som er viktig og velge ut fra det, så hadde man kanskje kommet ut med
7748 litt andre resultat. Jeg tror IT-folk er konservative og velger tradisjonelt
7749 og det er synd.

7753 <p
>Jeg bruker Ubuntu, Android, Jolicloud, Open Office, Zimbra, Picasa
7754 og Firefox samt en bråte med tjenester som er webbasert. Det eneste
7755 som er betalingslisens for er OSX. Ser at jeg jobber mer og mer i
7756 skyen og setter pris på alt jeg slipper egen klient til. Derfor er
7757 jeg veldig sjarmert av små kjappe operativsystemer som krever minimalt
7758 av maskinvaren.

7763 <p
>Tror en blanding av krav og informasjon er veien å gå. Krav om
7764 sikkerhet, oppetid og åpne standarder. Informasjon om muligheter og
7765 alternativer. Her har leverandører, IT-avdelinger og pedagoger en vei
7766 å gå sammen. Det er til slutt LÆRING det dreier seg om, og da må man
7767 få mest mulig læring for pengene man har.

>Sturle Sunde, ansvarleg for skulenettet i Flora kommune. Eg driv,
7785 vidareutviklar og er andrelinje brukarstøtte for datanettet ved
7786 skulane i Flora kommune.
10 skular og meir enn
700 maskiner med
7787 Linux, medrekna tynnklientar. Tidlegare jobba eg i mange år med
7788 unix-drift ved Universitetets senter for informasjonsteknologi ved
7789 Universitetet i Oslo.
</p
>
7791 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
7793 <p
>Det er vanskeleg å svare konkret på. Eg har drive med Unix og Linux i
7794 alle år, og Skulelinux er eit godt kjent prosjekt i miljøet. Det var
7795 først i
2008, då eg tok til i min noverande jobb, at eg fekk bruk for
7796 Skulelinux for alvor.
</p
>
7798 <p
>Jobben min skulle vere drift av eit nytt skulenett i Flora kommune,
7799 levert av eit firma eg ikkje vil reklamere for. Systemet skulle vere
7800 ferdig levert i september året før. Dette viste seg å ta mykje lenger
7801 tid, og i haustferien
2008 hadde dei endå ikkje klart å få opp ei
7802 fungerande løysing. Situasjonen var prekær for den største skulen i
7803 kommunen med meir enn
500 elevar på ungdomssteget. Skulen hadde brukt
7804 Skulelinux før, og var tilfredse med det. No hadde dei vore utan
7805 fungerande datasystem i nesten eit år. Difor fekk eg opp ein ny tenar
7806 utanfor prosjektet og installerte Skulelinux på den. Etter litt
7807 justering av konfigurasjonen med god hjelp av #skolelinux på IRC, var
7808 den nye tenaren oppe og gjekk med både tynne og halv-tjukke klientar.
7809 Autentisering gjekk mot det nye systemet, slik at elevar og lærarar
7810 framleis har same brukarnamn og passord over alt. Dette berre
7811 fungerte, og vi bestemte oss for å erstatte delar av løysinga vi
7812 skulle få levert med Skulelinux.
</p
>
7814 <p
>Det høyrer med til historia at det nye systemet eg skulle drive frå
7815 januar
2008 endå ikkje er ferdig levert. Dei jobbar med saka, seier
7816 dei, og har von om å fullføre leveransen i løpet av
2011.
</p
>
7818 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7820 <p
>Det er veldig mange. Eg skal ta nokre få.
</p
>
7822 <p
>Den viktigaste fordelen er at det igrunn berre er ei maskin å passe
7823 på, og det er tenaren. Med andre løysingar har ein gjerne programvare
7824 og anna som skal vedlikehaldast på kvar enkelt maskin. Med Skulelinux
7825 kan alle feil rettast og alle program oppgraderast på alle maskiner
7826 samstundes ved å gjere endringa som må til på tenaren. Eg kan sitje
7827 på kontoret og passe på alle tenarane i kommunen derifrå.
</p
>
7831 <li
>Tynne klientar gjer det mogleg å bruke eldre utstyr lenge, so lenge
7832 tenaren er sterk nok. Ein liten tenar med eit par halv-moderne CPUar
7833 og
2 GiB RAM held lenge for eit typisk klasserom med
30 tynnklientar,
7834 og det er lett å utvide med fleire.
7836 <li
>Halvtjukke klientar gjer det mogleg å utnytte kapasiteten i litt
7837 nyare maskiner betre, og avlaste tenaren. Ingenting vert installert
7838 lokalt på desse heller, og harddisken kan gjerne koblast frå. Gode
7839 halvtjukke klientar kan kjøpast brukt for under
1000-lappen, og det er
7840 heile kostnaden. Ingen lisensar eller anna på toppen, og det er ikkje
7841 krav til kraftigare tenar heller.
7843 <li
>Det er Linux. Vi har ikkje noko kluss med drivarar, dei berre er
7844 der. Heller ikkje med virus, dei finst i realiteten ikkje. Eller med
7845 elevar som klussar med installert programvare, for dei klarar ikkje å
7846 øydeleggje for nokon andre enn seg sjølve.
7850 <p
>Skulelinux er lagt opp til å vere veldig lett å installere rett ut
7851 av boksen på ein heil skule av ein interessert lærar. Det er ofte ei
7852 god løysing for skulen. Å ha nokon til stades som kjenner systemet og
7853 kan forklare enkle ting eller løyse problem der og då, er uvurderleg
7854 viktig for ein stressa lærar fem minutt før det ringer inn.
</p
>
7856 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7858 <p
>All den ferdige konfigurasjonen gjer det tungvint å tilpasse
7859 Skulelinux til eit system som skal fungere saman med mange andre
7860 installasjonar i eit felles datanett for skulane i ein kommune. Det
7861 heile er prekonfigurert for ein skule, og utviding til mange skular
7862 med eigne tenarar er ikkje berre enkelt.
</p
>
7864 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
7866 <p
>Eg brukar mest alle små hjelpeprogram som føl med operativsystemet,
7867 samt scriptspråket perl. Elles er Firefox/Iceweasel, Gnome-terminal
7868 og ssh i kontinuerleg bruk. Av Linux-distribusjonar brukar eg både
7869 Debian, Ubuntu, SuSE og RedHat dagleg. Eg prøvar å finne det verktyet
7870 som passar best til kvar del av jobben.

7872 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
7873 skoler til å ta i bruk fri programvare?
</strong
></p
>
7875 <p
>Det er to målgrupper ein må sikte mot. Det eine er alle skulane som
7876 manglar eller har eit lite tilfredsstillande opplegg i dag, og ikkje
7877 har råd til å kjøpe noko nytt og blankpussa opplegg. Der er det om å
7878 gjere å gjere det enkelt for skulane å finne Skulelinux, og gjere det
7879 enkelt for dei å få hjelp til installasjon på skulen. Gjerne med
7880 lokale kontaktpersonar. Her er det dugnadsinnsats som må til, for
7881 desse skulane har ikkje råd til å betale for dette.
</p
>
7883 <p
>Den andre og kanskje viktigare målgruppa er dei meir eller mindre
7884 profesjonelle kundane. Alle store offentlege innkjøp, inkludert
7885 innkjøp av nytt datasystem for skular, må ut på offentleg anbod.
7886 Offentlege anbod er mykje meir lukka enn dei gjev inntrykk av, og både
7887 regelboka og boka med triks for å sminke tilbodet er tjukk. Det er
7888 vanskeleg å komme inn utan eit solid salsapparat i ryggen. Kanskje
7889 Skulelinux skulle prøve aktivt å få seg eit partnarskap med eit av dei
7890 store som gjerne vil sterkare inn på den offentlege IT-marknaden?
7891 Nokon som kjenner triksa og har krefter til å ta opp kampen mot både
7892 dårlege anbod og Rudolf Blostrupmoen IT AS. Leveranse til skulane i
7893 ein kommune er ein god måte å få ein fot inn døra som leverandør til
7894 ein lukrativ kommunemarknad som kjøper alle tenester. Ta kontakt med
7895 nokon som er passeleg store og ikkje er Microsoft-partnar, og fortell:
7896 «Vi har eit ferdig produkt som du kan selje. Nei vi skal ikkje ha for
7897 det. Du kan gjerne gjere kva du vil med det, berre vi får lov til å
7898 hjelpe deg. Målgruppa er alle kommunar, og det er noko dei vil ha.
7899 Det er eit godt produkt, brukt av mange og godt likt.»

7925 <p
>Jeg leste en artikkel om en dugnadsinstallasjon av Skolelinux på en
7926 skole på Jæren et sted. Tanken om dugnad og frihet appellerte til
7927 meg. Da vi skulle bygge ny skole var det en del vi måtte spare på,
7928 fordi vi beveget oss mot en kostnadssprekk. Kabling og investering i
7929 PC-er var en av tingene vi sparte på. Derfor kjøpe vi
72 pc-er for
390
7930 pr stk. En filtjener og en applikasjonsserver.

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

7934 <p
>Fordelen er at så mye er satt opp fra starten. I tillegg er det
7935 tydelig at pakka er laga for skoleverket. Brukerne har egne
7936 skrivebord, tilgang på mange gode verktøyprogrammer. Vi slipper å
7937 tenke på virus. Brukerne har ikke mulighet til å ødelegge
7938 klientoppsett, men har gode muligheter til å endre eget oppsett. Dette
7939 tror jeg er inspirerende og kjekt for mange brukere. Mappestrukturen
7940 er ferdig og det er
"enkelt
" å designe lokale mappestrukturer via
7941 skeleton. Noen av oss i skoleverket mener skolen skal være en
7942 "mot-kultur
". Da er Skolelinux et av valgene man kan ta. Et annet er å
7943 spise på indisk restaurant i stedet for Mc Donald
's når vi er på bytur
7944 osv.. Ordene deling, frihet, dugnad osv er positive ord i
7945 skoleverket. Det er viktig at elevene blir bevisst dette.

</strong
></p

7949 <p
>Kompabiliteten er selvsagt et problem, selv om det er mindre nå enn
7950 før. For IKT-personer på skolene som skal drifte dette er det
7951 problematisk med kommandoer i terminalen. I tillegg er det alt for
7952 mange programmer i Skolelinux som ikke blir brukt. Jeg tror
7953 Skolelinux er tjent med å tone ned begrepet pedagogisk programvare.
7954 Slik jeg ser det finnes ikke denne kategorien programmer lengre slik
7955 de gjorde før, som frittsående programmer som installeres på en
7956 datamaskin eller på serveren. Det finnes en del spesialpedagogiske
7957 programmer, som Textpilot, LingDys, LingRight, AskiRaski, Ny i Norge
7958 osv. Men dette er programmer for enkelt-elever eller små grupper av
7959 elever. Det som bør være fokus er at alle undervisningsressurser som
7960 lages for nettet skal være nettleseruavhengig.

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

7964 <p
>OpenOffice bruker jeg til vanlig kontorarbeide. VLC bruker jeg som
7965 videoavspiller og av og til streaming av film. Gimp bruker jeg i
7966 undervisningen til bildemanipulering. Firefox og Chrome er mine
7967 favoritt-nettlesere. Firefox har lenge vært førstevalget mitt, nå
7968 bruker jeg mest Chrome. Opplever den som raskere og smidigere enn
7969 Firefox. Ubuntu bruker jeg som dualboot på jobb-maskinen min i
7970 tillegg til at alle PCer hjemme har en eller annen Ubuntu-distribusjon
7971 installert. Jeg bruker Clonezilla på Ubuntu
10.04 til kloning av
7972 datamaskiner på jobb. Det er selvsagt en haug andre frie programmer
7973 jeg bruker men jeg bruker dem ikke daglig. Jeg kan ramse opp:
7974 recordmydesktop, cinelerra, acidrip, soundjuicer, audacity, NX
7975 (no-machine), Kino, Rythmbox...

>Hvilken strategi tror du er den rette å bruke for å få
7978 skoler til å ta i bruk fri programvare?
</strong
></p
>
7980 <p
>Jeg tror oppsøkende virksomhet er den rette strategien.
7981 Ressurspersoner gjør avtaler med rådmenn, skolesjefer, rektorer. Det
7982 er slik konkurrentene gjør det. Fokuset i slike samtaler bør være
7983 kost-nytte. Dersom personer med økonomisk ansvar ser at de kan få
7984 like godt tilbud til mindre utgifter, tror jeg det er mulighet til å
7985 få innpass. Dersom de også kan få konkrete tilbud på drift i slike
7986 samtaler, vil de kanskje bli litt mer interesserte i hvor mye penger
7987 som faktisk går til IKT i skolene. Det er også viktig at vi ikke
7988 firer for mye på krav til datamaskiner. Det er flott at Skolelinux
7989 går på
"utrangert
" utstyr, men dette bør bare presenteres som et
7990 alternativ. Skolelinux-installasjoner med utrangert utstyr er ikke å
7991 foretrekke dersom man kan unngå det. Det skaper ikke entusiasme hos
7992 brukerne (elever og lærere) når de bruker gamle datamaskiner som går
7993 tregt. Det er kjempefint med skoler som har kommet seg frem til
7994 Skolelinux og fri programvare av seg selv, men de lever på nåde.
7995 Slike valg må fundamenteres hos skoleeier.

17
8019 servere basert på Skolelinux og Debian. Jeg holder i tillegg noen kurs

8026 <p
>Gjennom en eller annen nettavis i
2001 der var det skrevet om
8027 Skolelinux. Artikkelen ga meg lyst til å prøve ut systemet.
</p
>
8029 <p
>Det startet i
2002 ved at jeg installerte en av de første utgavene
8030 av Skolelinux på en standard pc på Solneset skole i Tromsø. Denne var
8031 oppe fram til desember
2003 da jeg sluttet på den skolen og begynte i
8032 ny jobb i Narvik kommune.
</p

8034 <p
> I Narvik kommune var det i
2004 kun
2 servere på da totalt
15
8035 skoler. Disse var Windows NT baserte. På disse to skolene var det lite
8036 med maskiner. Jobben med å få Narvik Kommune opp på akseptabelt nivå
8037 virket å være formidabel. Men med hjelp av gode kollegaer og leder
8038 skrev jeg en IKT plan for Narvik kommune som ble vedtatt av politikere
8039 i august
2004. I denne planen ble det bestemt at Narvik kommune skulle
8040 bruke Skolelinux. Her ble det også satt av midler til kabling av god
8041 infrastruktur på alle skoler samt innkjøp av nye datamaskiner. Så i
8042 dag har vi
17 servere hvorav
13 er på Skolelinux, med ca
1500 klienter

8083 er at de som til daglig bidrar til å fremme fri programvare i
8084 skoleverket og utvikler en linux-distribusjon spesiallaget for
8085 skolebruk kan bli bedre kjent og kanskje inspirere flere til å bidra
8086 til Skolelinux-prosjektet.

8099 Mitt navn er Arnt Ove Gregersen, jeg er
32 år og bor for tiden i Trondheim.
8101 Her jobber jeg som systemutvikler i et firma
8102 som heter
<a href=
"http://www.geomatikk-ikt.no/
">Geomatikk IKT AS
</a

8103 hvor jeg er på et Vegmeldings-prosjekt for Statens Vegvesen. På
8104 fritiden er jeg styreleder i FRISK (Fri programvare i skolen) og
8105 bidrar til bl.a. Skolelinux-prosjektet når jeg får tid til det. Det er
8106 primært hjemmesiden til Skolelinux-prosjektet og

</strong
></p

8113 <p
>Jeg var på en presentasjon av prosjektet i regi av Knut Yrvin på
8114 Gløshaugen i Trondheim, hvor jeg fattet stor interesse for prosjektet
8115 og ville hjelpe til så godt jeg kunne. Dette var vel i
2002 eller
8118 <p
>Jeg hadde fra før hørt om prosjektet fra før og syntes tanken bak var
8119 ganske fin, men hadde ikke noen interesse av bruke min egen fritid på
8122 <p
>I etterkant av presentasjonen startet jeg og noen andre fra
8123 Trondheim
"Skolelinux-prosjektet i Sør-Trøndelag
" . Hvor vi var med å
8124 bidra til at Trondheim kommune satte igang Selsbakk ungdomskole som et
8125 pilotprosjekt med Skolelinux, som egentlig var og er en stor suksess,
8126 men det virker ut som det ikke skjer noe mer på. I tillegg var vi med
8127 på dugnad på Brundalen videregående skole hvor vi installerte
8128 Skolelinux som såvidt jeg vet fortsatt kjører på Skolelinux.

</strong

8132 <p
>Det bygger på fri programvare og har lav kostnad i forhold til
8133 nytteverdien. Dette fordi det har forholdsvis lav inngangsum og bruker
8134 en arkitektur med sentral-drift som gir mange driftfordeler. I
8135 tillegg vil det kunne frigjøre kostnader for skolene slik at de kan
8136 bruke dem til å ansette f,eks flere lærere om det er ønskelig.

8145 <p
>Til utvikling av Java-applikasjoner og Android bruker jeg Eclipse og
8146 Quanta til web-utvikling via php. For all bildebehandling bruker jeg
8147 GIMP og Blender til
3d-modellering . Dessverre har Blender en bratt
8148 læringskurve i starten, men det er absolutt verdt det.
8150 <p
>Til musikk bruker jeg stort Rhytmbox. Firefox til surfing på nettet og
8151 Thunderbird og Evolution til e-post,
8153 <p

">skolen
8171 i Hemsedal har fått ødelagt

>av Inspektør Siri (gjest)
8178 <p
>Kommunen min har to omtrent jevnstore tettsteder, og en
8179 ungdomsskole i hvert av tettstedene. Den minste av disse har ca
300
8180 elever og til denne sogner det
3 barneskoler. Den største har ca
350
8181 elever og til denne sogner det
4 barneskoler.
</p
>
8185 <li
>Kommunen har i veldig lang tid forsømt IKT i skolen, og det har
8186 bare blitt gitt smuler i ny og ne. Det er kun den største av
8187 ungdomsskolene som har hatt en skikkelig datapark, og dette takket
8188 være en naturfaglærer som ble lei av å vente på kommunen. Det gjorde
8189 at vi bestemte oss for å ta ting i egne hender, og da vha
8190 skolelinux. En testinstallasjon med
10 gamle PCer ble gjort, og vi så
8191 raskt at dette var veldig lovende. Neste etappe var å gi alle lærere
8192 egen PC på arbeidsplassene sine (
2004), og så sette opp
16 PCer på to
8193 datarom. Vi har kun basert oss på å kjøpe inn brukte maskiner, og
8194 aldri dyrere enn
1000 kr pr klient. For to år siden så hadde vi
8195 klienter i alle klasserom, og totalt hadde vi da rundt
250 stk. Rundt
8196 40 klienter brukes av lærerne og kjører på en egen server. Elvene har
8197 resten, og kjører også en egen server. Servere har vi også kjøpt
8198 brukt,
2 år gamle servere koster
6-
7000 kroner.
</li
>
8200 <li
>Skolen vår er et relativt gammelt bygg, men en meget dyktig
8201 vaktmester har sammen med IKT-ansvarlig/Naturfaglærer lagt kabler til alle
8202 rom. Gradvis har vi byttet ut billige svitsjer med mer solide saker
8203 som er mulig å fjernstyre.
</li
>
8205 <li
>Vi har i all hovedsak greid å få dette til over eget budsjett, men
8206 vi har også passet på å få penger når de andre skolene har fått
8207 bærbare PCer til lærere osv.
</li
>
8209 <li
>Vår IKT-ansvarlig har gjort (og gjør) en fenomenal jobb, og vi har
8210 en maskinpark som de andre av kommunens skoler bare kan drømme
8215 <p
>Så skjer det som ofte skjer. Det kommer en eller annen
8216 selger/blåruss og skal fikse ALT. I vårt tilfelle betyr dette også
8217 sentralisering av drift. Den ny-ansatte på kommunens IT-avdelingen
8218 skal også ha jobb, og ser for seg å ta over skoledriften. Kommunen
8219 kjøper inn eksterne driftstjenester, og nekter i samme slengen å ta
8220 hensyn til skolen vår. Dette til tross for at vi alene har like mange
8221 datamaskiner som de andre til sammen.
</p
>
8225 <li
>Det blir krevd at vi skal innlemmes i de kommunale systemet, og
8226 det er VI som får ansvar for at dette kommer på plass. Og det er her
8227 de horrible tingene begynner å skje.
</li
>
8229 <li
>Det settes opp en lukket Exchange server som gjør av vi ikke kan
8230 hente epost for våre ansatte. Og det kreves at vi finner løsning på
8233 <li
>Det velges sak arkivsystem som vi pålegges å bruke, noe som gjør
8234 at vi må bruke en terminalløsning mot kommunal server. Ikke i seg selv
8235 et problem i følge IKT-ansvarlig hos oss. Men kommunens IT-avd nektet
8236 faktisk å åpne de porter OSV som vi måtte bruke.
</li
>
8238 <li
>Vi blir pålagt å flytte på innsiden av det kommunale
8239 nettverket. Dette gjorde at vi mistet hjemmekontor for lærere og
8240 elever. Å få åpnet porter i kommunal brannmur var ikke
8241 aktuelt. Mulighet for fjerndrift ble også vekk i samme slengen.
</li
>
8243 <li
>Vår LMS Moodle er ikke mulig å nå for elevene og lærerne.
8247 <p
>Den andre ungdomsskolen i kommunen begynner så å kreve at de skal
8248 få bedre datatetthet, og komme opp på et nivå som ligner det vi
8249 har. De ser at vi kan avholde eksamen hvor alle
10. klassingene får
8250 sitte ved hver sin PC. Og de har fått tilbakemelding (klager) fra VGS
8251 om manglende datakompetanse på elevene som kommer fra dem. Dette fører
8252 videre til at kommunen endelig innser at de må ta grep.
</p
>
8254 <p
>Grepet betyr sentralisering, og farvel til vår plattform får vi
8255 høre. Det blir gjort en rekke bestemmelser og vedtak som vi ikke får
8256 være en del av. Det blir helt klart at vi må redusere antall maskiner,
8257 og det skal satses på bærbare maskiner. Siden vi ikke har fått tatt
8258 del i prosessene som angår oss, så bruker vi fagforening. Vi har ikke
8259 blitt hørt i forbindelse med endringer som er betydelig for vår
8260 hverdag, og greier å stoppe omlegging. I tillegg så har vi et politisk
8261 vedtak i kommunen på at vi skal kjøre Linux på elevnett, og dette
8262 vedtaket kan ikke administrasjonen i kommunene helt uten videre
8263 tilsidesette.
</p
>
8265 <p
>I sum har dette gjort at vi har fått jobbe videre i fred. Og en del
8266 runder i kommunens kontrollutvalg har gjort det tydelig at vi har blitt
8267 systematisk motarbeidet.
</p
>
8269 <p
>I dag har de andre skolene fått sine bærbare maskiner til elever og
8270 lærere, men etter
2 år med innkjøring er det fremdeles problemer
8275 <li
>Ungdomsskolen med windows kan ikke kjøre eksamen med sine bærbare,
8276 det er for mye arbeid å renske disse for innhold slik at juks ikke er

>Utskrift er et mareritt, etter sigende pga at utskrift først
8280 sendes til sentral server, og så sendes ut til rett skriver. I snitt
8281 så tar det
7-
8 minutter før utskrift starter på enkelte av

>Trådløst skaper store problemer, og det er i perioder helt umulig
8285 å komme seg på nett. Og lagring på felles server er bare å glemme i
8286 perioder.
</li
>
8290 <p
>Vi har slitt mye, kranglet og sloss. Ikke med tekniske problemer,
8291 men med omgivelsene rundt som vil oss til livs. Men det har vært verdt
8292 hver dråpe med svette, og timer med irritasjon. Men vi har begynt å få
8293 rutine her nå.

8299 <li

8336 leserinnlegg myntet på aviser. Disse er ikke sendt til aviser, men
8337 brukt internt i forbindelse med møter med kommune. Vår IKT-ansvarlig
8338 har også truet med å si opp jobben sin hvis det ikke ble tatt hensyn i
8339 større grad enn hva som har vært tilfelle. VI kan også dokumentere
8340 flere brudd på anbudsregler, og vi kjenner til at relativt store
8341 IT-leverandører som ikke har fått tatt del i disse anbudene, rett og
8342 slett ikke tør melde fra av redsel for å få et dårlig rykte.

8344 <p
>Alt ser ut til å roe seg ned, og vi har fått opp øynene på
8345 politikerne. I sum gjør dette at vi ikke ønsker for mye publisitet nå,
8346 det vil bare rote til igjen.
</p

8348 <p
>Jeg glemte å nevne at vi nå nesten ikke bruker tid på å drifte
8349 systemet vårt, noe som gjør at det aller meste av tid blir brukt til å
8350 støtte lærerne og elevene. F.eks så bruker vår IKT-ansvarlig den
8351 første timen på jobb,
0730-
0830 kun til å gå ute på arbeidsplassene
8352 til læreren. Dette for å kunne svare på små og store problem, gi tips
8353 og råd, eller bare for å plukke opp hva som er behovet ute i
8354 undervisningsarealene. Det er dessverre ikke slik at alle lærerne har
8355 nok digital kompetanse til å kunne formulere alle spørsmålene de har,
8356 men ved å kunne få vise eller lufte tanker med IKT-ansvarlig så er det
8357 utrolig hva som kommer fram.
</p
>
8361 <li
>Jeg ser at mange bruker økonomi som argument i forhold til å bruke
8362 SkoleLinux, og jeg skal ikke legge skjul på at det var dette som i
8363 utgangspunktet var årsaken til vårt valg. Men diskusjonene og kampen
8364 med kommunens IT-avdeling har gjort at vi har fått et noe annet
8365 fokus. Fordelene med drift og stabilitet, gjør at vi ville ha valgt
8366 samme løsning selv om den var dyrere. At vi slipper langt billigere
8367 unna, som følge av
0,- lisenskostnader og lave maskinvarekostnader, er
8368 bare en bonus.
</li
>
8370 <li
>Etter å ha kranglet oss til å få skikkelig oversikt over hva de
8371 andre skolene i kommunen bruker på IT, så har vi fått gehør for å få
8372 samme midler til innkjøp. Dette har gjort at vi nå kan kjøpe inn
8373 utstyr som de andre skolene bare kan se langt etter. Vi har nettopp
8374 kjøpt inn
3 videokamera i semiproff-klassen for å kunne lage film,
8375 samt sende live fra skoleteater/konserter. Vi har kjøpt inn digitale
8376 kompaktkamera til alle klassene. Vi har et team av lærere som skal i
8377 gang med å teste ut tablets på svake elever. Håpet et at teknologien
8378 kan være med på å gi noen av elevene litt mer motivasjon. Vi har kjøpt
8379 inn et halvt klassesett med pulsklokker, noe som har vist seg å være
8380 overraskende inspirerende for en del av elevene. Vi har også oss på
8381 fag på en høyskole litt lengre sør for oss, slik at
3 av oss nå skal
8382 ta faget
"Linux tjenestedrift
". Som inspektør og en del av skolens
8383 administrasjon er det veldig praktisk å kunne trå til hvis det
8384 kniper. Men IKT-ansvarlig har vært UTROLIG flink til å lage rene
8385 smørbrødlister for hvordan de mest vanlige driftsproblem løses, så det
8386 er lett for flere av oss å ta del i den daglige driften. Vi har svært
8387 stor nytte av lærling (som også hjelper to av naboskolene), men det er
8388 nesten blitt slik at det er om å gjøre å komme til først for å få løse
8389 problem. Det å få fingrene på problem og utfordringer er den aller
8390 beste læremester.
</li
>
8394 <p
>Når vi nå tar til med planlegging av ny skole, så vil det være med
8395 tanke på at det skal være mulig med datautstyr på alle plasser. Vi
8396 kommer i all hovedsak til å legge kabel til alle tenkelige og
8397 utenkelige plasser. WiFi koster tilnærmet NULL å sette opp i
8400 <p
>Vi har ikke vært noe flink til å bidra til SkoleLinux-prosjektet,
8401 vi har rett og slett vært for opptatt med vår egen kamp. Vi har hentet
8402 mye inspirasjon fra diskusjoner som har gått i det miljøet, og vi
8403 håper at vi nå framover kan få tid til å bidra. Vi er i ferd med å
8404 bytte ut en av serverne våre, og da vil denne trolig bli satt opp som
8405 testserver for neste versjon av Skolelinux. På den måten vil vi i alle
8406 fall kunne gi tilbakemeldinger og rapportere feil. I tillegg så vil
8407 det kanskje gi oss noen nye utfordringer, for som lærlingen vår sier:
8408 "Skolelinux er noe herk, det skjer jo ikke noe galt og hvordan skal

8427 years the university have organised shared bid of a few thousand
8428 computers, and this year HP won the bid. Two different desktops and
8429 five different laptops are on the list this year. We in the UNIX

8435 perhaps inspire others to test hardware as well. To test, I PXE
8436 install the OS version of choice, and log in as my normal user and run
8437 a few applications and plug in selected pieces of hardware. When
8438 something fail, I make a note about this in the test matrix and move
8439 on. If I have some spare time I try to report the bug to the OS
8440 vendor, but as I only have the machines for a short time, I rarely
8441 have the time to do this for all the problems I find.

8536 <title>Why isn

8540 <description><p
>In the latest issue of Linux Journal, the readers choices were
8541 presented, and the winner among the multimedia player were VLC.
8542 Personally, I like VLC, and it is my player of choice when I first try
8543 to play a video file or stream. Only if VLC fail will I drag out
8544 gmplayer to see if it can do better. The reason is mostly the failure
8545 model and trust. When VLC fail, it normally pop up a error message
8546 reporting the problem. When mplayer fail, it normally segfault or
8547 just hangs. The latter failure mode drain my trust in the program.
<p
>
8549 <p
>But even if VLC is my player of choice, we have choosen to use
8550 mplayer in
<a href=
"http://www.skolelinux.org/
">Debian
8551 Edu/Skolelinux
</a
>. The reason is simple. We need a good browser
8552 plugin to play web videos seamlessly, and the VLC browser plugin is
8553 not very good. For example, it lack in-line control buttons, so there
8554 is no way for the user to pause the video. Also, when I
8555 <a href=
"http://wiki.debian.org/DebianEdu/BrowserMultimedia
">last
8556 tested the browser plugins
</a
> available in Debian, the VLC plugin
8557 failed on several video pages where mplayer based plugins worked. If
8558 the browser plugin for VLC was as good as the gecko-mediaplayer
8559 package (which uses mplayer), we would switch.
</P
>
8561 <p
>While VLC is a good player, its user interface is slightly
8562 annoying. The most annoying feature is its inconsistent use of
8563 keyboard shortcuts. When the player is in full screen mode, its
8564 shortcuts are different from when it is playing the video in a window.
8565 For example, space only work as pause when in full screen mode. I
8566 wish it had consisten shortcuts and that space also would work when in
8567 window mode. Another nice shortcut in gmplayer is [enter] to restart
8568 the current video. It is very nice when playing short videos from the
8569 web and want to restart it when new people arrive to have a look at
8570 what is going on.

9026 are virtual machines. And they have been Xen machines running on a
9027 fairly old IBM eserver xseries
345 machine, and we wanted to migrate
9028 them to KVM on a newer Dell PowerEdge
2950 host machine. This was a
9029 bit harder that it could have been, because we set up the Xen virtual
9030 machines to get the virtual partitions from LVM, which as far as I
9031 know is not supported by KVM. So to migrate, we had to convert
9032 several LVM logical volumes to partitions on a virtual disk file.

9039 image partions as devices, and dd to copy the data. I NFS mounted the

9339 TB zfs volume we currently use to store DV video. Because of this, I
9340 finally got around to do a test installation of Debian/Squeeze with
9341 kfreebsd. Installation went fairly smooth, thought I noticed some
9342 visual glitches in the cdebconf dialogs (black cursor left on the
9343 screen at random locations). Have not gotten very far with the
9344 testing. Noticed cfdisk did not work, but fdisk did so it was not a
9345 fatal problem. Have to spend some more time on it to see if it is
9346 useful as a file server for NUUG. Will try to find time to set up a
9347 gnash buildbot slave on the Debian Edu/Skolelinux this weekend.

>Prioritising packages for the Debian Edu /
9357 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
> DVD, which is
9358 supposed provide a school with all the services and user applications
9359 needed on the pupils computer network has always been hard. Even
9360 schools without Internet connections should be able to get Debian Edu
9361 working using this DVD.
</p
>
9363 <p
>The job became a lot harder when apt and aptitude started
9364 installing recommended packages by default. We want the same set of
9365 packages to be installed when using the DVD and the netinst CD, and
9366 that means all recommended packages need to be on the DVD. I created
9367 a patch for debian-cd in
<a href=
"http://bugs.debian.org/
601203">BTS
9368 report #
601203</a
> to do this, and since this change was applied to
9369 the Debian Edu DVD build, we have been seriously short on space.
</p
>
9371 <p
>A few days ago we decided to drop blender, wxmaxima and kicad from
9372 the default installation to save space on the DVD, believing that
9373 those needing these applications are few and can get them from the
9374 Debian archive.
</p
>
9376 <p
>Yesterday, I had a look what source packages to see which packages
9377 were using most space. A few large packages are well know;
9378 openoffice.org, openclipart and fluid-soundfont. But I also
9379 discovered that lilypond used
106 MiB and fglrx-driver used
53 MiB.
9380 The lilypond package is pulled in as a dependency for rosegarden, and
9381 when looking a bit closer I discovered that
99 MiB of the
106 MiB were
9382 the documentation package, which is recommended by the binary package.
9383 I decided to drop this documentation package from our DVD, as most of
9384 our users will use the GUI front-ends and do not need the lilypond
9385 documentation. Similarly, I dropped the non-free fglrx-driver package
9386 which might be installed by d-i when its hardware is detected, as the
9387 free X driver should work.
</p
>
9389 <p
>With this change, we finally got space for the LXDE and Gnome
9390 desktop packages as well as the language specific packages making the
9391 DVD more useful again.

9402 <p

<a href=

">gnash pledge
</a
> to
9403 raise money for the project is going well. The lower limit of
10
9404 signers was reached in
24 hours, and so far
13 people have signed it.
9405 More signers and more funding is most welcome, and I am really curious
9406 how far we can get before the time limit of December
24 is reached.
9409 <p
>On the #gnash IRC channel on irc.freenode.net, I was just tipped
9410 about what appear to be a great code coverage tool capable of
9411 generating code coverage stats without any changes to the source code.

&gt;
</tt
>.
9415 It is missing in Debian, but the git source built just fine in Squeeze
9416 after I installed libelf-dev, libdwarf-dev, pkg-config and
9417 libglib2.0-dev. Failed to build in Lenny, but suspect that is
9418 solvable. I hope kcov make it into Debian soon.

9425 release. Give it a try if you need a complete linux solution for your
9426 school, including central infrastructure server, workstations, thin
9427 client servers and diskless workstations. A nice touch added
9428 yesterday is RDP support on the thin client servers, for windows
9429 clients to get a Linux desktop on request.

9439 popularity-contest numbers
</a

9440 second most popular used package that is missing in Debian. The sixth
9441 most popular is flashplayer-mozilla. This is a clear indication that
9442 working flash is important for Debian users. Around
10 percent of the
9443 users submitting data to popcon.debian.org have this package
9444 installed.

9446 <p

">Skolelinux
9448 i bruk – Rapport for Hurum kommune, Universitetet i Agder og
9449 stiftelsen SLX Debian Labs

>»), one of the most important problems
9450 schools experienced with
<a href=
"http://www.skolelinux.org/
">Debian
9451 Edu/Skolelinux
</a
> was the lack of working Flash. A lot of educational
9452 web sites require Flash to work, and lacking working Flash support in
9453 the web browser and the problems with installing it was perceived as a
9454 good reason to stay with Windows.
</p
>
9456 <p
>I once saw a funny and sad comment in a web forum, where Linux was
9457 said to be the retarded cousin that did not really understand
9458 everything you told him but could work fairly well. This was a
9459 comment regarding the problems Linux have with proprietary formats and
9460 non-standard web pages, and is sad because it exposes a fairly common
9461 understanding of whose fault it is if web pages that only work in for
9462 example Internet Explorer
6 fail to work on Firefox, and funny because
9463 it explain very well how annoying it is for users when Linux
9464 distributions do not work with the documents they receive or the web
9465 pages they want to visit.
</p
>
9467 <p
>This is part of the reason why I believe it is important for Debian
9468 and Debian Edu to have a well working Flash implementation in the
9469 distribution, to get at least popular sites as Youtube and Google
9470 Video to working out of the box. For Squeeze, Debian have the chance
9471 to include the latest version of Gnash that will make this happen, as
9472 the new release
0.8.8 was published a few weeks ago and is resting in
9473 unstable. The new version work with more sites that version
0.8.7.
9474 The Gnash maintainers have asked for a freeze exception, but the
9475 release team have not had time to reply to it yet. I hope they agree
9476 with me that Flash is important for the Debian desktop users, and thus
9477 accept the new package into Squeeze.

9519 har vært rullet ut i noen måneder nå, og så vidt jeg fikk vite før

9521 høst. På alle skolene skal en kunne velge ved installasjon om en skal
9522 ha Windows eller Skolelinux på maskinene, og en kan i tillegg
9523 PXE-boote maskinene over nett som tynne klienter eller diskløse
9524 arbeidsstasjoner. Jeg er spent på hvor mange skoler som velger å ta i
9525 bruk Skolelinux, og gleder meg til å se hvordan dette utvikler seg.
9526 Løsningen leveres av

9528 <a href=

9547 work as a unix home directory,and today I had to extend it a bit. I
'm
9548 looking into alternatives for home directory access here at the
9549 University of Oslo, and one of the options is sshfs. My friend
9550 Finn-Arne mentioned a while back that they had used sshfs with Debian
9551 Edu, but stopped because of problems. I asked today what the problems
9552 where, and he mentioned that sshfs failed to handle umask properly.
9553 Trying to detect the problem I wrote this addition to my fs testing
9557 mode_t touch_get_mode(const char *name, mode_t mode) {
9559 int fd = open(name, O_RDWR|O_CREAT|O_LARGEFILE, mode);

9651 <description><p
>As reported earlier, the last few days I have looked at how Debian
9652 Edu clients are configured, and tried to get rid of all hardcoded
9653 configuration settings on the clients. I believe the work to be
9654 mostly done, and the clients seem to work just fine with dynamically
9655 generated configuration.
</p
>
9657 <p
>What is the point, you might ask? The point is to allow a Debian
9658 Edu desktop to integrate into an existing network infrastructure
9659 without any manual configuration.
</p
>
9661 <p
>This is what happens when installing a Debian Edu client here at
9662 the University of Oslo using PXE. With the PXE installation, I am
9663 asked for language (Norwegian Bokmål), locality (Norway) and keyboard
9664 layout (no-latin1), Debian Edu profile (Roaming Workstation), if I
9665 accept to reformat the hard drive (yes), if I want to submit info to
9666 popcon.debian.org (no) and root password (secret). After answering
9667 these questions, the installer goes ahead and does its thing, and
9668 after around
50 minutes it is done. I press enter to finish the
9669 installation, and the machine reboots into KDE. When the machine is
9670 ready and kdm asks for login information, I enter my university
9671 username and password, am told by kdm that a local home directory has
9672 been created and that I must log in again, and finally log in with the
9673 same username and password to the KDE
4.4 desktop. At no point during
9674 this process did it ask for university specific settings, and all the
9675 required configuration was dynamically detected using information
9676 fetched via DHCP and DNS. The roaming workstation is now ready for
9679 <p
>How was this done, you might wonder? First of all, here is the
9680 list of things that need to be configured on the client to get it
9681 working properly out of the box:
</p
>
9684 <li
>IP address/netmask and DNS server.
</li
>
9685 <li
>Web proxy URL.
</li
>
9686 <li
>LDAP server for NSS directory information (user, group, etc).
</li
>
9687 <li
>Kerberos server for PAM password checking.
</li
>
9688 <li
>SMB mount point to access the network home directory. (*)
</li
>
9689 <li
>Central syslog server to send syslog messages to. (*)
</li
>
9690 <li
>Sitesummary collector URL to submit info to central server. (*)
</li
>
9693 <p
>(Hm, did I forget anything? Let me knew if I did.)
</p
>
9695 <p
>The points marked (*) are not required to be able to use the
9696 machine, but needed to provide central storage and allowing system
9697 administrators to track their machines. Since yesterday, everything
9698 but the sitesummary collector URL is dynamically discovered at boot
9699 and installation time in the svn version of Debian Edu.
</p
>
9701 <p
>The IP and DNS setup is fetched during boot using DHCP as usual.
9702 When a DHCP update arrives, the proxy setup is updated by looking for
9703 http://wpat/wpad.dat and using the content of this WPAD file to
9704 configure the http and ftp proxy in /etc/environment and
9705 /etc/apt/apt.conf. I decided to update the proxy setup using a DHCP
9706 hook to ensure that the client stops using the Debian Edu proxy when
9707 it is moved outside the Debian Edu network, and instead uses any local
9708 proxy present on the new network when it moves around.
</p
>
9710 <p
>The DNS names of the LDAP, Kerberos and syslog server and related
9711 configuration are generated using DNS information at boot. First the
9712 installer looks for a host named ldap in the current DNS domain. If
9713 not found, it looks for _ldap._tcp SRV records in DNS instead. If an
9714 LDAP server is found, its root DSE entry is requested and the
9715 attributes namingContexts and defaultNamingContext are used to
9716 determine which LDAP base to use for NSS. If there are several
9717 namingContexts attibutes and the defaultNamingContext is present, that
9718 LDAP subtree is used as the base. If defaultNamingContext is missing,
9719 the subtrees listed as namingContexts are searched in sequence for any
9720 object with class posixAccount or posixGroup, and the first one with
9721 such an object is used as the LDAP base. For Kerberos, a similar
9722 search is done by first looking for a host named kerberos, and then
9723 for the _kerberos._tcp SRV record. I
've been unable to find a way to
9724 look up the Kerberos realm, so for this the upper case string of the
9725 current DNS domain is used.
</p
>
9727 <p
>For the syslog server, the hosts syslog and loghost are searched
9728 for, and the _syslog._udp SRV record is consulted if no such host is
9729 found. This algorithm works for both Debian Edu and the University of
9730 Oslo. A similar strategy would work for locating the sitesummary
9731 server, but have not been implemented yet. I decided to fetch and
9732 save these settings during installation, to make sure moving to a
9733 different network does not change the set of users being allowed to
9734 log in nor the passwords required to log in. Usernames and passwords
9735 will be cached by sssd when the user logs in on the Debian Edu
9736 network, and will not change as the laptop move around. For a
9737 non-roaming machine, there is no caching, but given that it is
9738 supposed to stay in place it should not matter much. Perhaps we
9739 should switch those to use sssd too?
</p
>
9741 <p
>The user
's SMB mount point for the network home directory is
9742 located when the user logs in for the first time. The LDAP server is
9743 consulted to look for the user
's LDAP object and the sambaHomePath
9744 attribute is used if found. If it isn
't found, the home directory
9745 path fetched from NSS is used instead. Assuming the path is of the
9746 form /site/server/directory/username, the second part is looked up in
9747 DNS and used to generate a SMB URL of the form
9748 smb://server.domain/username. This algorithm works for both Debian
9749 edu and the University of Oslo. Perhaps there are better attributes
9750 to use or a better algorithm that works for more sites, but this will
9751 do for now. :)
</p
>
9753 <p
>This work should make it easier to integrate the Debian Edu clients
9754 into any LDAP/Kerberos infrastructure, and make the current setup even
9755 more flexible than before. I suspect it will also work for thin
9756 client servers, allowing one to easily set up LTSP and hook it into a
9757 existing network infrastructure, but I have not had time to test this
9760 <p
>If you want to help out with implementing these things for Debian
9761 Edu, please contact us on debian-edu@lists.debian.org.
</p
>
9763 <p
>Update
2010-
08-
09: Simon Farnsworth gave me a heads-up on how to
9764 detect Kerberos realm from DNS, by looking for _kerberos TXT entries
9765 before falling back to the upper case DNS domain name. Will have to
9766 implement it for Debian Edu. :)

9775 <description><p
>A few years ago, I was involved in a project planning to use
9776 Windows file servers as home directory servers for Debian
9777 Edu/Skolelinux machines. This was thought to be no problem, as the
9778 access would be through the SMB network file system protocol, and we
9779 knew other sites used SMB with unix and samba as the file server to
9780 mount home directories without any problems. But, after months of
9781 struggling, we had to conclude that our goal was impossible.
</p
>
9783 <p
>The reason is simply that while SMB can be used for home
9784 directories when the file server is Samba running on Unix, this only
9785 work because of Samba have some extensions and the fact that the
9786 underlying file system is a unix file system. When using a Windows
9787 file server, the underlying file system do not have POSIX semantics,
9788 and several programs will fail if the users home directory where they
9789 want to store their configuration lack POSIX semantics.
</p
>
9791 <p
>As part of this work, I wrote a small C program I want to share
9792 with you all, to replicate a few of the problematic applications (like
9793 OpenOffice.org and GCompris) and see if the file system was working as
9794 it should. If you find yourself in spooky file system land, it might

10009 while on the university network here at the University of Oslo, and
10010 noticed how much had to change to get it operational using the
10011 university infrastructure. It was fairly easy, but it occured to me
10012 that Debian Edu would improve a lot if I could get the client to
10013 connect without any changes at all, and thus let the client configure
10014 itself during installation and first boot to use the infrastructure
10015 around it. Now I am a huge step further along that road.
</p
>
10017 <p
>With our current squeeze-test packages, I can select the roaming
10018 workstation profile and get a working laptop connecting to the
10019 university LDAP server for user and group and our active directory
10020 servers for Kerberos authentication. All this without any
10021 configuration at all during installation. My users home directory got
10022 a bookmark in the KDE menu to mount it via SMB, with the correct URL.
10023 In short, openldap and sssd is correctly configured. In addition to
10024 this, the client look for http://wpad/wpad.dat to configure a web
10025 proxy, and when it fail to find it no proxy settings are stored in
10026 /etc/environment and /etc/apt/apt.conf. Iceweasel and KDE is
10027 configured to look for the same wpad configuration and also do not use
10028 a proxy when at the university network. If the machine is moved to a
10029 network with such wpad setup, it would automatically use it when DHCP
10030 gave it a IP address.

10032 <p
>The LDAP server is located using DNS, by first looking for the DNS
10033 entry ldap.$domain. If this do not exist, it look for the
10034 _ldap._tcp.$domain SRV records and use the first one as the LDAP
10035 server. Next, it connects to the LDAP server and search all
10036 namingContexts entries for posixAccount or posixGroup objects, and
10037 pick the first one as the LDAP base. For Kerberos, a similar
10038 algorithm is used to locate the LDAP server, and the realm is the
10039 uppercase version of $domain.
</p
>
10041 <p
>So, what is not working, you might ask. SMB mounting my home
10042 directory do not work. No idea why, but suspected the incorrect
10043 Kerberos settings in /etc/krb5.conf and /etc/samba/smb.conf might be
10044 the cause. These are not properly configured during installation, and
10045 had to be hand-edited to get the correct Kerberos realm and server,
10046 but SMB mounting still do not work. :(
</p
>
10048 <p
>With this automatic configuration in place, I expect a Debian Edu
10049 roaming profile installation would be able to automatically detect and
10050 connect to any site using LDAP and Kerberos for NSS directory and PAM
10051 authentication. It should also work out of the box in a Active
10052 Directory environment providing posixAccount and posixGroup objects
10053 with UID and GID values.

>The new roaming workstation profile in Debian Edu/Squeeze is fairly
10066 similar to the laptop setup am I working on using Ubuntu for the
10067 University of Oslo, and just for the heck of it, I tested today how
10068 hard it would be to integrate that profile into the university
10069 infrastructure. In this case, it is the university LDAP server,
10070 Active Directory Kerberos server and SMB mounting from the Netapp file
10073 <p
>I was pleasantly surprised that the only three files needed to be
10074 changed (/etc/sssd/sssd.conf, /etc/ldap.conf and
10075 /etc/mklocaluser.d/
20-debian-edu-config) and one file had to be added
10076 (/usr/share/perl5/Debian/Edu_Local.pm), to get the client working.
10077 Most of the changes were to get the client to use the university LDAP
10078 for NSS and Kerberos server for PAM, but one was to change a hard
10079 coded DNS domain name in the mklocaluser hook from .intern to
10082 <p
>This testing was so encouraging, that I went ahead and adjusted the
10083 Debian Edu scripts and setup in subversion to centralise the roaming
10084 workstation setup a bit more and avoid the hardcoded DNS domain name,
10085 so that when I test this tomorrow, I expect to get away with modifying
10086 only /etc/sssd/sssd.conf and /etc/ldap.conf to get it to use the
10087 university servers.
</p
>
10089 <p
>My goal is to get the clients to have no hardcoded settings and
10090 fetch all their initial setup during installation and first boot, to
10091 allow them to be inserted also into environments where the default
10092 setup in Debian Edu has been changed or as with the university, where
10093 the environment is different but provides the protocols Debian Edu

10109 release is to test the user application selection. To have a look,
10110 install the standalone profile and let the developers know if the set
10111 of installed packages i.e. applications should be modified. If some
10112 user application is missing, or if there are some applications that no
10113 longer make sense to be included in Debian Edu, please let us know.
10114 Also, if a useful application is missing the translation for your
10115 language of choice, please let us know too.

>The last few months me and the other Debian Edu developers have
10223 been working hard to get the Debian/Squeeze based version of Debian
10224 Edu/Skolelinux into shape. This future version will use Kerberos for
10225 authentication, and services are slowly migrated to single signon,
10226 getting rid of password questions one at the time.
</p
>
10228 <p
>It will also feature a roaming workstation profile with local home
10229 directory, for laptops that are only some times on the Skolelinux
10230 network, and for this profile a shortcut is created in Gnome and KDE
10231 to gain access to the users home directory on the file server. This
10232 shortcut uses SMB at the moment, and yesterday I had time to test if
10233 SMB mounting had started working in KDE after we added the cifs-utils
10234 package. I was pleasantly surprised how well it worked.
</p
>
10236 <p
>Thanks to the recent changes to our samba configuration to get it
10237 to use Kerberos for authentication, there were no question about user
10238 password when mounting the SMB volume. A simple click on the shortcut
10239 in the KDE menu, and a window with the home directory popped
10242 <p
>One step closer to a single signon solution out of the box in
10243 Debian Edu. We already had PAM, LDAP, IMAP and SMTP in place, and now
10244 also Samba. Next step is Cups and hopefully also NFS.

10246 <p
>We had planned a alpha0 release of Debian Edu for today, but thanks
10247 to the autobuilder administrators for some architectures being slow to
10248 sign packages, we are still missing the fixed LTSP package we need for
10249 the release. It was uploaded three days ago with urgency=high, and if
10250 it had entered testing yesterday we would have been able to test it in
10251 time for a alpha0 release today. As the binaries for ia64 and powerpc
10252 still not uploaded to the Debian archive, we need to delay the alpha
10253 release another day.

>For a while now, I have wanted to find a way to change the DNS and
10585 DHCP services in Debian Edu to use the same LDAP objects for a given
10586 computer, to avoid the possibility of having a inconsistent state for
10587 a computer in LDAP (as in DHCP but no DNS entry or the other way
10588 around) and make it easier to add computers to LDAP.
</p

10590 <p

've looked at how powerdns and dhcpd is using LDAP, and using this
10591 information finally found a solution that seem to work.
</p

10593 <p
>The old setup required three LDAP objects for a given computer.
10594 One forward DNS entry, one reverse DNS entry and one DHCP entry. If
10595 we switch powerdns to use its strict LDAP method (ldap-method=strict
10596 in pdns-debian-edu.conf), the forward and reverse DNS entries are
10597 merged into one while making it impossible to transfer the reverse map
10598 to a slave DNS server.
</p
>
10600 <p
>If we also replace the object class used to get the DNS related
10601 attributes to one allowing these attributes to be combined with the
10602 dhcphost object class, we can merge the DNS and DHCP entries into one.
10603 I
've written such object class in the dnsdomainaux.schema file (need
10604 proper OIDs, but that is a minor issue), and tested the setup. It
10605 seem to work.
</p
>
10607 <p
>With this test setup in place, we can get away with one LDAP object
10608 for both DNS and DHCP, and even the LTSP configuration I suggested in
10609 an earlier email. The combined LDAP object will look something like

10630 <p

10631 dhcphost in a different location, to allow us to put the objects
10632 outside the

10633 that. If I can
't figure out a way to do that, we can still get rid of
10634 the hosts subtree and move all its content into the DHCP Config tree
10635 (which probably should be renamed to be more related to the new

10652 Debian Edu choose to store configuration there.
</p

10654 <p

10655 to get configuration from LDAP. The idea is to look up the MAC

10853 <description><p
>For a laptop, centralized user directories and password checking is
10854 a bit troubling. Laptops are typically used also when not connected
10855 to the network, and it is vital for a user to be able to log in or
10856 unlock the screen saver also when a central server is unavailable.
10857 This is possible by caching passwords and directory information (user
10858 and group attributes) locally, and the packages to do so are available
10859 in Debian. Here follow two recipes to set this up in Debian/Squeeze.
10860 It is also possible to set up in Debian/Lenny, but require more manual
10861 setup there because pam-auth-update is missing in Lenny.
</p
>
10863 <h2
>LDAP/Kerberos + nscd + libpam-ccreds + libpam-mklocaluser/pam_mkhomedir
</h2
>
10865 This is the traditional method with a twist. The password caching is
10866 provided by libpam-ccreds (version
10-
4 or later is needed on
10867 Squeeze), and the directory caching is done by nscd. The directory
10868 lookup and password checking is done using LDAP. If one want to use
10869 Kerberos for password checking the libpam-ldapd package can be
10870 replaced with libpam-krb5 or libpam-heimdal. If one is happy having a
10871 local home directory with the path listed in LDAP, one can use the
10872 pam_mkhomedir module from pam-modules to make this happen instead of
10873 using libpam-mklocaluser. A setup for pam-auth-update to enable
10874 pam_mkhomedir will have to be written until a fix for
10875 <a href=
"http://bugs.debian.org/
568577">bug #
568577</a
> is in the
10876 archive. Because I believe it is a bad idea to have local home
10877 directories using misleading paths like /site/server/partition/, I
10878 prefer to create a local user with the home directory in /home/. This
10879 is done using the libpam-mklocaluser package.

've been unable to get TLS

>The last few days I have been looking into the status of the LDAP
11060 directory in Debian Edu, and in the process I started to miss a GUI
11061 tool to browse the LDAP tree. The only one I was able to find in
11062 Debian/Squeeze and Lenny is
11063 <a href=
"http://luma.sourceforge.net/
">LUMA
</a
>, which has proved to
11064 be a great tool to get a overview of the current LDAP directory
11065 populated by default in Skolelinux. Thanks to it, I have been able to
11066 find empty and obsolete subtrees, misplaced objects and duplicate
11067 objects. It will be installed by default in Debian/Squeeze. If you
11068 are working with LDAP, give it a go. :)
</p
>
11070 <p
>I did notice one problem with it I have not had time to report to
11071 the BTS yet. There is no .desktop file in the package, so the tool do
11072 not show up in the Gnome and KDE menus, but only deep down in in the
11073 Debian submenu in KDE. I hope that can be fixed before Squeeze is
11074 released.
</p
>
11076 <p
>I have not yet been able to get it to modify the tree yet. I would
11077 like to move objects and remove subtrees directly in the GUI, but have
11078 not found a way to do that with LUMA yet. So in the mean time, I use
11079 <a href=

11085 <a href=
"http://packages.qa.debian.org/g/gq.html
">gq
</a
> package as a
11086 useful GUI alternative. It seem like a good tool, but is unmaintained
11087 in Debian and got a RC bug keeping it out of Squeeze. Unless that
11088 changes, it will not be an option for Debian Edu based on Squeeze.

11152 I am now testing dist-upgrade of Gnome and KDE in a chroot using both
11153 apt and aptitude, and found their differences interesting. This time
11154 I will only focus on their removal plans.
</p
>
11156 <p
>After installing a Gnome desktop and the laptop task, apt-get wants
11157 to remove
72 packages when dist-upgrading from Lenny to Squeeze. The
11158 surprising part is that it want to remove xorg and all
11159 xserver-xorg-video* drivers. Clearly not a good choice, but I am not
11160 sure why. When asking aptitude to do the same, it want to remove
129
11161 packages, but most of them are library packages I suspect are no
11162 longer needed. Both of them want to remove bluetooth packages, which
11163 I do not know. Perhaps these bluetooth packages are obsolete?
</p
>
11165 <p
>For KDE, apt-get want to remove
82 packages, among them kdebase
11166 which seem like a bad idea and xorg the same way as with Gnome. Asking
11167 aptitude for the same, it wants to remove
192 packages, none which are
11168 too surprising.
</p
>
11170 <p
>I guess the removal of xorg during upgrades should be investigated
11171 and avoided, and perhaps others as well. Here are the complete list
11172 of planned removals. The complete logs is available from the URL
11173 above. Note if you want to repeat these tests, that the upgrade test
11174 for kde+apt-get hung in the tasksel setup because of dpkg asking
11175 conffile questions. No idea why. I worked around it by using
11176 '<tt

11323 <description><p
>The last few days I have done some upgrade testing in Debian, to
11324 see if the upgrade from Lenny to Squeeze will go smoothly. A few bugs
11325 have been discovered and reported in the process
11326 (
<a href=
"http://bugs.debian.org/
585410">#
585410</a
> in nagios3-cgi,
11327 <a href=
"http://bugs.debian.org/
584879">#
584879</a
> already fixed in
11328 enscript and
<a href=
"http://bugs.debian.org/
584861">#
584861</a
> in
11329 kdebase-workspace-data), and to get a more regular testing going on, I
11330 am working on a script to automate the test.
</p
>
11332 <p
>The idea is to create a Lenny chroot and use tasksel to install a
11333 Gnome or KDE desktop installation inside the chroot before upgrading
11334 it. To ensure no services are started in the chroot, a policy-rc.d
11335 script is inserted. To make sure tasksel believe it is to install a
11336 desktop on a laptop, the tasksel tests are replaced in the chroot
11337 (only acceptable because this is a throw-away chroot).
</p
>
11339 <p
>A naive upgrade from Lenny to Squeeze using aptitude dist-upgrade
11340 currently always fail because udev refuses to upgrade with the kernel
11341 in Lenny, so to avoid that problem the file /etc/udev/kernel-upgrade
11342 is created. The bug report
11343 <a href=
"http://bugs.debian.org/
566000">#
566000</a
> make me suspect
11344 this problem do not trigger in a chroot, but I touch the file anyway
11345 to make sure the upgrade go well. Testing on virtual and real
11346 hardware have failed me because of udev so far, and creating this file
11347 do the trick in such settings anyway. This is a
11348 <a href=
"http://www.linuxquestions.org/questions/debian-
26/failed-dist-upgrade-due-to-udev-config_sysfs_deprecated-nonsense-
804130/
">known
11349 issue
</a
> and the current udev behaviour is intended by the udev
11350 maintainer because he lack the resources to rewrite udev to keep
11351 working with old kernels or something like that. I really wish the
11352 udev upstream would keep udev backwards compatible, to avoid such
11353 upgrade problem, but given that they fail to do so, I guess
11354 documenting the way out of this mess is the best option we got for
11355 Debian Squeeze.
</p
>

11358 script, which I call

11436 <p
>I am very happy to notice that the Gnome desktop + laptop upgrade
11437 is able to migrate to dependency based boot sequencing and parallel
11438 booting without a hitch. Was unsure if there were still bugs with
11439 packages failing to clean up their obsolete init.d script during
11440 upgrades, and no such problem seem to affect the Gnome desktop+laptop
11441 packages.

>Som systemarkitekten bak Skolelinux, kan jeg bare riste på hodet
11481 over påstanden om at Skolelinux krever desentraliserte tjenere.
11482 Skolelinux-arkitekturen er laget for sentralisert drift og plassering
11483 av tjenerne lokalt eller sentralt alt etter behov og nettkapasitet.
11484 Den er modellert på nettverks- og tjenerløsningen som brukes på
11485 Universitetet i Tromsø og Oslo, der jeg jobber med utvikling av
11486 driftstjenester. Dette er det heldigvis noen som har fått med seg, og
11487 jeg er glad for å kunne sitere fra en kommentar på den overnevnte
11488 artikkelen. Min venn og gamle kollega Sturle Sunde forteller der:
11491 <p
>I Flora kommune køyrer vi Skulelinux på skular med alt frå
15 til
11492 meir enn
500 elevar. Dei store skulane har eigen tenar, for det er
11493 mest praktisk. Eg, som er driftsansvarleg for heile nettet, ser
11494 sjeldan dei tenarane fysisk, men at dei står der gjer skulane mindre
11495 avhengige av eksterne linjer som er trege eller dyre. Dei minste
11496 skulane har ikkje eigen tenar. Å bruke sentral tenar er heller ikkje
11497 noko problem. Småskulane klarar seg fint med
1 mbit-linje til ein
11498 sentral tenar eller tenaren på ein større skule.
</p
>
11500 <p
>Det beste med Skulelinux er halvtjukke klientar. Dei treng ikkje
11501 harddisk og brukar minimalt med ressursar på tenaren fordi dei køyrer
11502 programma lokalt. Eit klasserom med
30 sju-åtte år gamle maskiner har
11503 mykje meir CPU og RAM totalt enn nokon moderne tenar til under
11504 millionen. Det trengst to kommandoar på den sentrale tenaren for å
11505 oppdatere alle klientane, både tynne og halvtjukke. Vi har ingen
11506 problem med diskar som ryk heller, som var eit problem før fordi
11507 elevane sat og sparka i maskinene. Og dei krev lite bandbreidde i
11508 nettet, so det er fullt mogleg å køyre slike på småskular med trege
11509 linjer mot tenaren på ein større skule.
</p
>
11511 <p
>Flora kommune har nesten
800 Linux-maskiner i sitt skulenett, og
11512 ein person som tek seg av drift av heile nettet, inkludert tenarar,
11513 klientar, operativsystem, programvare, heimekontorløysing og
11514 administrasjon av brukarar.
</p
>
11516 <p
>No skal det seiast at vi ikkje køyrer rein Skulelinux ut av
11517 boksen. Vi har gjort ein del tilpassingar mot noko Novell-greier som
11518 var der frå før, og som har komplisert installasjonen vår. Etter at
11519 oppsettet var gjort har løysinga vore stabil og kravd minimalt med

>After a long break from debian-installer development, I finally
11668 found time today to return to the project. Having to spend less time
11669 working dependency based boot in debian, as it is almost complete now,
11670 definitely helped freeing some time.
</p
>
11672 <p
>A while back, I ran into a problem while working on Debian Edu. We
11673 include some firmware packages on the Debian Edu CDs, those needed to
11674 get disk and network controllers working. Without having these
11675 firmware packages available during installation, it is impossible to
11676 install Debian Edu on the given machine, and because our target group
11677 are non-technical people, asking them to provide firmware packages on
11678 an external medium is a support pain. Initially, I expected it to be
11679 enough to include the firmware packages on the CD to get
11680 debian-installer to find and use them. This proved to be wrong.
11681 Next, I hoped it was enough to symlink the relevant firmware packages
11682 to some useful location on the CD (tried /cdrom/ and
11683 /cdrom/firmware/). This also proved to not work, and at this point I
11684 found time to look at the debian-installer code to figure out what was
11685 going to work.
</p
>
11687 <p
>The firmware loading code is in the hw-detect package, and a closer
11688 look revealed that it would only look for firmware packages outside
11689 the installation media, so the CD was never checked for firmware
11690 packages. It would only check USB sticks, floppies and other
11691 "external
" media devices. Today I changed it to also look in the
11692 /cdrom/firmware/ directory on the mounted CD or DVD, which should
11693 solve the problem I ran into with Debian edu. I also changed it to
11694 look in /firmware/, to make sure the installer also find firmware
11695 provided in the initrd when booting the installer via PXE, to allow us
11696 to provide the same feature in the PXE setup included in Debian
11699 <p
>To make sure firmware deb packages with a license questions are not
11700 activated without asking if the license is accepted, I extended
11701 hw-detect to look for preinst scripts in the firmware packages, and
11702 run these before activating the firmware during installation. The
11703 license question is asked using debconf in the preinst, so this should
11704 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
11717 Edu finally entered the Debian archive. Today, the new
11718 <a href=
"http://packages.qa.debian.org/libp/libpam-mklocaluser.html
">libpam-mklocaluser
</a
>
11719 package was accepted. Two days ago, two other pieces was accepted
11721 <a href=
"http://packages.qa.debian.org/p/pam-python.html
">pam-python

11722 package needed by libpam-mklocaluser, and the
11723 <a href=
"http://packages.qa.debian.org/s/sssd.html
">sssd
</a
> package
11724 passed NEW on Monday. In addition, the
11725 <a href=
"http://packages.qa.debian.org/libp/libpam-ccreds.html
">libpam-ccreds
</a
>
11726 package we need is in experimental (version
10-
4) since Saturday, and
11727 hopefully will be moved to unstable soon.
</p
>
11729 <p
>This collection of packages allow for two different setups for
11730 roaming laptops. The traditional setup would be using libpam-ccreds,
11731 nscd and libpam-mklocaluser with LDAP or Kerberos authentication,
11732 which should work out of the box if the configuration changes proposed
11733 for nscd in
<a href=
"http://bugs.debian.org/
485282">BTS report
11734 #
485282</a
> is implemented. The alternative setup is to use sssd with
11735 libpam-mklocaluser to connect to LDAP or Kerberos and let sssd take
11736 care of the caching of passwords and group information.
</p
>
11738 <p
>I have so far been unable to get sssd to work with the LDAP server
11739 at the University, but suspect the issue is some SSL/GnuTLS related
11740 problem with the server certificate. I plan to update the Debian
11741 package to version
1.2, which is scheduled for next week, and hope to
11742 find time to make sure the next release will include both the
11743 Debian/Ubuntu specific patches. Upstream is friendly and responsive,
11744 and I am sure we will find a good solution.
</p
>
11746 <p
>The idea is to set up the roaming laptops to authenticate using
11747 LDAP or Kerberos and create a local user with home directory in /home/
11748 when a usre in LDAP logs in via KDM or GDM for the first time, and
11749 cache the password for offline checking, as well as caching group
11750 memberhips and other relevant LDAP information. The
11751 libpam-mklocaluser package was created to make sure the local home
11752 directory is in /home/, instead of /site/server/directory/ which would
11753 be the home directory if pam_mkhomedir was used. To avoid confusion
11754 with support requests and configuration, we do not want local laptops
11755 to have users in a path that is used for the same users home directory
11756 on the home directory servers.
</p
>
11758 <p
>One annoying problem with gdm is that it do not show the PAM
11759 message passed to the user from libpam-mklocaluser when the local user
11760 is created. Instead gdm simply reject the login with some generic
11761 message. The message is shown in kdm, ssh and login, so I guess it is
11762 a bug in gdm. Have not investigated if there is some other message
11763 type that can be used instead to get gdm to also show the message.

11933 the laptop is requested and a local home directory is set up for
11934 the user, with uid and gid information fetched from the LDAP
11935 server. This allow the user to work also when offline. The
11936 central home directory can be available in a subdirectory on
11937 request, for example mounted via CIFS. It could be mounted
11938 automatically when a user log in while on the Debian Edu network,
11939 and unmounted when the machine is taken away (network down,
11940 hibernate, etc), it can be set up to do automatic mounting on
11941 request (using autofs), or perhaps some GUI button on the desktop
11942 can be used to access it when needed. Perhaps it is enough to use

11947 to cache the password for offline checking when the machine unable

11977 (
<a href=

11978 perhaps debian-edu-config) should get some integration code to stop
11979 its daemon when the LDAP server is unavailable to avoid long timeouts
11980 when disconnected from the net. If we get Kerberos enabled, we need
11981 to make sure we avoid long timeouts there too.

11994 NUUG presentation
</a
> about Kerberos was inspiring, and reminded me
11995 about the need to start using Kerberos in Skolelinux. Setting up a
11996 Kerberos server seem to be straight forward, and if we get this in
11997 place a long time before the Squeeze version of Debian freezes, we
11998 have a chance to migrate Skolelinux away from NFSv3 for the home
11999 directories, and over to an architecture where the infrastructure do
12000 not have to trust IP addresses and machines, and instead can trust
12001 users and cryptographic keys instead.
</p
>
12003 <p
>A challenge will be integration and administration. Is there a
12004 Kerberos implementation for Debian where one can control the
12005 administration access in Kerberos using LDAP groups? With it, the
12006 school administration will have to maintain access control using flat
12007 files on the main server, which give a huge potential for errors.
</p

12009 <p
>A related question I would like to know is how well Kerberos and
12010 pam-ccreds (offline password check) work together. Anyone know?
</p
>
12012 <p
>Next step will be to use Kerberos for access control in Lwat and
12013 Nagios. I have no idea how much work that will be to implement. We
12014 would also need to document how to integrate with Windows AD, as such
12015 shared network will require two Kerberos realms that need to cooperate
12016 to work properly.
</p
>
12018 <p
>I believe a good start would be to start using Kerberos on the
12019 skolelinux.no machines, and this way get ourselves experience with
12020 configuration and integration. A natural starting point would be
12021 setting up ldap.skolelinux.no as the Kerberos server, and migrate the
12022 rest of the machines from PAM via LDAP to PAM via Kerberos one at the

>If you would like to contribute to get this working in Skolelinux,
12026 I recommend you to see the video recording from yesterdays NUUG

>6 years ago, as part of the Debian Edu development I am involved
12038 in, I asked for a hook in the kdm and gdm setup to run scripts as root
12039 when the user log out. A bug was submitted against the xfree86-common
12040 package in
2004 (
<a href=
"http://bugs.debian.org/

230422</a

12041 and revisited every time Debian Edu was working on a new release.
12042 Today, this finally paid off.
</p

12044 <p
>The framework for this feature was today commited to the git
12045 repositry for the xorg package, and the git repository for xdm has
12046 been updated to use this framework. Next on my agenda is to make sure
12047 kdm and gdm also add code to use this framework.
</p
>
12049 <p
>In Debian Edu, we want to ability to run commands as root when the
12050 user log out, to get rid of runaway processes and do general cleanup
12051 after a user. With this framework in place, we finally can do that in
12052 a generic way that work with all display managers using this
12053 framework. My goal is to get all display managers in Debian use it,
12054 similar to how they use the Xsession.d framework today.

>One of the new features in the next Debian/Lenny based release of
12086 Debian Edu/Skolelinux, which is scheduled for release in the next few
12087 days, is automatic configuration of the service monitoring system
12088 Nagios. The previous release had automatic configuration of trend
12089 analysis using Munin, and this Lenny based release take that a step
12092 <p
>When installing a Debian Edu Main-server, it is automatically
12093 configured as a Munin and Nagios server. In addition, it is
12094 configured to be a server for the
12095 <a href=
"http://wiki.debian.org/DebianEdu/HowTo/SiteSummary
">SiteSummary
12096 system
</a
> I have written for use in Debian Edu. The SiteSummary
12097 system is inspired by a system used by the University of Oslo where I
12098 work. In short, the system provide a centralised collector of
12099 information about the computers on the network, and a client on each
12100 computer submitting information to this collector. This allow for
12101 automatic information on which packages are installed on each machine,
12102 which kernel the machines are using, what kind of configuration the
12103 packages got etc. This also allow us to automatically generate Munin
12104 and Nagios configuration.
</p
>
12106 <p
>All computers reporting to the sitesummary collector with the
12107 munin-node package installed is automatically enabled as a Munin
12108 client and graphs from the statistics collected from that machine show
12109 up automatically on http://www/munin/ on the Main-server.
</p
>
12111 <p
>All non-laptop computers reporting to the sitesummary collector are
12112 automatically monitored for network presence (ping and any network
12113 services detected). In addition, all computers (also laptops) with
12114 the nagios-nrpe-server package installed and configured the way
12115 sitesummary would configure it, are monitored for full disks, software
12116 raid status, swap free and other checks that need to run locally on
12117 the machine.
</p
>
12119 <p
>The result is that the administrator on a school using Debian Edu
12120 based on Lenny will be able to check the health of his installation
12121 with one look at the Nagios settings, without having to spend any time
12122 keeping the Nagios configuration up-to-date.
</p
>
12124 <p
>The only configuration one need to do to get Nagios up and running
12125 is to set the password used to get access via HTTP. The system
12126 administrator need to run
"<tt
>htpasswd /etc/nagios3/htpasswd.users
12127 nagiosadmin
</tt
>" to create a nagiosadmin user and set a password for
12128 it to be able to log into the Nagios web pages. After that,
12129 everything is taken care of.

12203 get to know the Skolelinux system. Walter Bender, involved in the

12205 also helped me improve my OLPC installation. He also showed me that
12206 his Turtle Art application can be used in standalone mode, and we

12290 byggsystemet og datafilen helt til jeg fikk samme resultat med det
12291 gamle og det nye byggsystemet. Dette tror jeg var forsøk
4, der de
12292 foregående har feilet uten at jeg klarte å forstå hvorfor. Det sier
12293 kanskje litt om kompleksiteten i det originale byggsystemet som Rune
12294 Kleveland laget i sin tid.

12302 skulle nå
10350 nye ord bli godkjent som korrekt stavede ord av

>This weekend we had a small developer gathering for Debian Edu in
12313 Oslo. Most of Saturday was used for the general assemly for the
12314 member organization, but the rest of the weekend I used to tune the
12315 LTSP installation. LTSP now work out of the box on the
10-network.
12316 Acer Aspire One proved to be a very nice thin client, with both
12317 screen, mouse and keybard in a small box. Was working on getting the
12318 diskless workstation setup configured out of the box, but did not
12319 finish it before the weekend was up.

12321 <p
>Did not find time to look at the
4 VGA cards in one box we got from
12322 the Brazilian group, so that will have to wait for the next
12323 development gathering. Would love to have the Debian Edu installer
12324 automatically detect and configure a multiseat setup when it find one
12325 of these cards.

>Recently I have spent some time evaluating the multimedia browser
12335 plugins available in Debian Lenny, to see which one we should use by
12336 default in Debian Edu. We need an embedded video playing plugin with
12337 control buttons to pause or stop the video, and capable of streaming
12338 all the multimedia content available on the web. The test results and
12339 notes are available on
12340 <a href=
"http://wiki.debian.org/DebianEdu/BrowserMultimedia
">the
12341 Debian wiki
</a
>. I was surprised how few of the plugins are able to
12342 fill this need. My personal video player favorite, VLC, has a really
12343 bad plugin which fail on a lot of the test pages. A lot of the MIME
12344 types I would expect to work with any free software player (like
12345 video/ogg), just do not work. And simple formats like the
12346 audio/x-mplegurl format (m3u playlists), just isn
't supported by the
12347 totem and vlc plugins. I hope the situation will improve soon. No
12348 wonder sites use the proprietary Adobe flash to play video.
