>It was a surprise to me to learn that project to create a complete
15 computer system for schools I
've involved in,
16 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>, was
17 being used in India. But apparently it is, and I managed to get an
18 interview with one of the friends of the project there, Shirish
21 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
23 <p
>My name is Shirish Agarwal. Based out of the educational and
24 historical city of Pune, from the western state of Maharashtra, India.
25 My bread comes from giving training, giving policy tips,
26 installations on free software to mom and pop shops in different
27 fields from Desktop publishing to retail shops as well as work with
28 few software start-ups as well.
</p
>
30 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
31 project?
</strong
></p
>
33 <p
>It started innocently enough. I have been using Debian for a few
34 years and in one local minidebconf / debutsav I was asked if there was
35 anything for schools or education. I had worked / played with free
36 educational softwares such as Gcompris and Stellarium for my many
37 nieces and nephews so researched and found Debian Edu or Skolelinux as
38 it was known then. Since then I have started using the various
39 education meta-packages provided by the project.
</p
>
41 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
42 Edu?
</strong
></p
>
44 <p
>It
's closest I have seen where a package full of educational
45 software are packed, which are free and open (both literally and
46 figuratively). Even if I take the simplest software which is
47 gcompris, the number of activities therein are amazing. Another one of
48 the softwares that I have liked for a long time is stellarium. Even
49 pysycache is cool except for couple of issues I encountered
50 <a href=
"https://bugs.debian.org/
781841">#
781841</a
> and
51 <a href=
"https://bugs.debian.org/
781842">#
781842</a
>.
</p
>
53 <p
>I prefer software installed on the system over web based solutions,
54 as a web site can disappear any time but the software on disk has the
55 possibility of a larger life span. Of course with both it
's more a
56 question if it has enough users who make it fun or sustainable or both
57 for the developer per-se.
</p
>
59 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
60 Edu?
</strong
></p
>
62 <p
>I do see that the Debian Edu team seems to be short-handed and I
63 think more efforts should be made to make it popular and ask and take
64 help from people and the larger community wherever possible.
</p
>
66 <p
>I don
't see any disadvantage to use Skolelinux apart from the fact
67 that most apps. are generic which is good or bad how you see it.
68 However, saying that I do acknowledge the fact that the canvas is
69 pretty big and there are lot of interesting ideas that could be done
70 but for reasons not known not done or if done I don
't know about them.
71 Let me share some of the ideas (these are more upstream based but
72 still) I have had for a long time :
</p
>
74 <p
>1. Classical maths question of two trains in opposing directions
75 each running @x kmph/mph at y distance, when they will meet and how
76 far would each travel and similar questions like these.
78 <p
>The computer is a fantastic system where questions like these can
79 be drawn, animated and the methodology and answers teased out in
80 interactive manner. While sites such as the
81 <a href=
"http://mathforum.org/dr.math/faq/faq.two.trains.html
">Ask
82 Dr. Math FAQ on The Two Trains problem
</a
> (as an example or point of
83 inspiration) can be used there is lot more that can be done. I dunno
84 if there is a free software which does something like this. The idea
85 being a blend of objects + animation + interaction which does
86 this. The whole interaction could be gamified with points or sounds or
87 colourful celebration whenever the user gets even part of the question
88 or/and methodology right. That would help reinforce good behaviour.
89 This understanding could be used to share/showcase everything from how
90 the first wheel came to be, to evolution to how astronomy started,
91 psychics and everything in-between.
</p
>
93 <p
>One specific idea in the train part was having the Linux mascot on
94 one train and the BSD or GNU mascot on the other train and they
95 meeting somewhere in-between. Characters from blender movies could
96 also be used.
</p
>
98 <p
>2. Loads of crossword-puzzles with reference to subjects: We have
99 enormous data sets in Wikipedia and Wikitionary. I don
't think it
100 should be a big job to design crossword puzzles. Using categories and
101 sub-categories it should be doable to have Q
&A single word answers
102 from the existing data-sets. What would make it easy or hard could be
103 the length of the word + existence of many or few vowels depending on
104 the user
's input.
</p
>
106 <p
>3. Jigsaw puzzles - We already have a great software called
107 palapeli with number of slicers making it pretty interesting. What
108 needs to be done is to download large number of public domain and
109 copyleft images, tease and use IPTC tags to categorise them into
110 nature, history etc. and let it loose. This could turn to be really
111 huge collection of images. One source could be taken from
112 commons.wikimedia.org, others could be huge collection of royalty-free
113 stock photos. Potential is immense.
</p
>
115 <p
>Apart from this, free software suffers in two directions, we lag
116 both in development (of using new features per-se) and maintenance a
117 lot. This is more so in educational software as these applications
118 need to be timely and the opportunity cost of missing deadlines is
119 immense. If we are able to solve issues of funding for development and
120 maintenance of such software I don
't see any big difficulties. I know
121 of few start-ups in and around India who would love to develop and
122 maintain such software if funding issues could be solved.
</p
>
124 <p
><strong
>Which free software do you use daily?
</strong
></p
>
126 <p
>That would be huge list. Some of the softwares are obviously apt,
127 aptitude, debdelta, leafpad, the shell of course (zsh nowadays),
128 quassel for IRC. In games I use shisen-sho while card-games are evenly
129 between kpat and Aiselriot. In desktops it
's a tie between
130 gnome-flashback and mate.
</p
>
132 <p
><strong
>Which strategy do you believe is the right one to use to
133 get schools to use free software?
</strong
></p
>
135 <p
>I think it should first start with using specific FOSS apps. in
136 whatever environment they are. If it
's MS-Windows or Mac so be it.
137 Once they are habitual with the apps. and there is buy-in from the
138 school management then it could be installed anywhere. Most of the
139 people now understand the concept of a repository because of the
140 various online stores so it isn
't hard to convince on that front.
</p
>
142 <p
>What is harder is having enough people with technical skills and
143 passion to service them. If you get buy-in from one or two teachers
144 then ideas like above could also be asked to be done as a project as
147 <p
>I think where we fall short more than anything is in marketing. For
148 instance, Debian has this whole range of fonts in its archive but
149 there isn
't even a page where all those different fonts in the La
150 Ipsum format could be tried out for newcomers.
</p
>
152 <p
>One of the issues faced constantly in installations is with updates
153 and upgrades. People have this myth that each update and upgrade
154 means the user interface will / has to change. I have seen this
155 innumerable times. That perhaps is one of the reasons which browsers
156 like Iceweasel / Firefox change user interfaces so much, not because
157 it might be needed or be functional but because people believe that
158 changed user interfaces are better. This, can easily be pointed with
159 the user interfaces changed with almost every MS-Windows and Mac OS
162 <p
>The problems with Debian Edu for deployment are many. The biggest
163 is the huge gap between what is taught in schools and what Debian Edu
166 <p
>Me and my friends did teach on week-ends in a government school for
168 <a href=
"https://flossexperiences.wordpress.com/
2012/

08/sharings/
">gathered
169 some experience
</a
> there. Some of the things we learnt/discovered
170 there was :
</p
>
174 <li
>Most of the teachers are very territorial about their subjects
175 and they do not want you to teach anything out of the
176 portion/syllabus given.
</li
>
178 <li
>They want any activity on the system in accordance to whatever
179 is in the syllabus.
</li
>
181 <li
>There are huge barriers both with the English language and at
182 times with objects or whatever. An example, let
's say in gcompris
183 you have objects falling down and you have to name them and let
's
184 say the falling object is a hat or a fedora hat, this would not be
185 as recognizable as say a
186 <a href=
"https://en.wikipedia.org/wiki/Puneri_Pagadi
">Puneri
187 Pagdi
</a
> so there is need to inject local objects, words wherever
188 possible. Especially for word-games there are so many hindi words
189 which have become part of english vocabulary (for instance in
190 parley), those could be made into a hinglish collection or
191 something but that is something for upstream to do.

228 Would you like to give your school
's computer a longer life? Are you
229 tired of sneaker administration, running from computer to computer
230 reinstalling the operating system? Would you like to administrate all
231 the computers in your school using only a couple of hours every week?
232 Check out Debian Edu Jessie!
234 Skolelinux is used by at least two hundred schools all over the world,
235 mostly in Germany and Norway.
237 About Debian Edu and Skolelinux
238 ===============================
240 Debian Edu, also known as Skolelinux[
2], is a Linux distribution based
241 on Debian providing an out-of-the box environment of a completely
242 configured school network. Immediately after installation a school
243 server running all services needed for a school network is set up just
244 waiting for users and machines being added via GOsa², a comfortable
245 Web-UI. A netbooting environment is prepared using PXE, so after
246 initial installation of the main server from CD or USB stick all other
247 machines can be installed via the network. The provided school server
248 provides LDAP database and Kerberos authentication service,
249 centralized home directories, DHCP server, web proxy and many other
250 services. The desktop contains more than
60 educational software
251 packages[
3] and more are available from the Debian archive, and
252 schools can choose between KDE, Gnome, LXDE, Xfce and MATE desktop

394 Edu on machines with disk (and a few other services perhaps to small
395 to mention here). We in the Debian Edu team are currently working on
396 the Jessie based version, trying to get everything in shape before the
397 freeze, to avoid having to maintain our own package repository in the

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

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

>
409 ftp.skolelinux.org::cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-
1.iso).
410 The ISO build was broken on Tuesday, so we do not get a new ISO every
411 12 hours or so, but thankfully the ISO we already got we are able to
412 install with some tweaking.
</p
>
414 <p
>When you get to the Debian Edu profile question, go to tty2
415 (use Alt-Ctrl-F2), run
</p
>
417 <p
><blockquote
><pre
>
418 nano /usr/bin/edu-eatmydata-install
419 </pre
></blockquote
></p
>
421 <p
>and add
'exit
0' as the second line, disabling the eatmydata
422 optimization. Return to the installation, select the profile you want
423 and continue. Without this change, exim4-config will fail to install
424 due to a known bug in eatmydata.
</p
>
426 <p
>When you get the grub question at the end, answer /dev/sda (or if
427 this do not work, figure out what your correct value would be. All my
428 test machines need /dev/sda, so I have no advice if it do not fit
431 <p
>If you installed a profile including a graphical desktop, log in as
432 root after the initial boot from hard drive, and install the
433 education-desktop-XXX metapackage. XXX can be kde, gnome, lxde, xfce
434 or mate. If you want several desktop options, install more than one
435 metapackage. Once this is done, reboot and you should have a working
436 graphical login screen. This workaround should no longer be needed
437 once the education-tasks package version
1.801 enter testing in two
440 <p
>I believe the ISO build will start working on two days when the new
441 tasksel package enter testing and Steve McIntyre get a chance to
442 update the debian-cd git repository. The eatmydata, grub and desktop
443 issues are already fixed in unstable and testing, and should show up
444 on the ISO as soon as the ISO build start working again. Well the
445 eatmydata optimization is really just disabled. The proper fix
446 require an upload by the eatmydata maintainer applying the patch
447 provided in bug
<a href=
"https://bugs.debian.org/
702711">#
702711</a
>.
448 The rest have proper fixes in unstable.
</p
>
450 <p
>I hope this get you going with the installation testing, as we are
451 quickly running out of time trying to get our Jessie based
452 installation ready before the distribution freeze in a month.

>The
<a href=
"https://www.debian.org/
">Debian
</a
> installer could be
462 a lot quicker. When we install more than
2000 packages in
463 <a href=
"http://www.skolelinux.org/
">Skolelinux / Debian Edu
</a
> using
464 tasksel in the installer, unpacking the binary packages take forever.
465 A part of the slow I/O issue was discussed in
466 <a href=
"https://bugs.debian.org/
613428">bug #
613428</a
> about too
467 much file system sync-ing done by dpkg, which is the package
468 responsible for unpacking the binary packages. Other parts (like code
469 executed by postinst scripts) might also sync to disk during
470 installation. All this sync-ing to disk do not really make sense to
471 me. If the machine crash half-way through, I start over, I do not try
472 to salvage the half installed system. So the failure sync-ing is
473 supposed to protect against, hardware or system crash, is not really
474 relevant while the installer is running.
</p
>
476 <p
>A few days ago, I thought of a way to get rid of all the file
477 system sync()-ing in a fairly non-intrusive way, without the need to
478 change the code in several packages. The idea is not new, but I have
479 not heard anyone propose the approach using dpkg-divert before. It
480 depend on the small and clever package
481 <a href=
"https://packages.qa.debian.org/eatmydata
">eatmydata
</a
>, which
482 uses LD_PRELOAD to replace the system functions for syncing data to
483 disk with functions doing nothing, thus allowing programs to live
484 dangerous while speeding up disk I/O significantly. Instead of
485 modifying the implementation of dpkg, apt and tasksel (which are the
486 packages responsible for selecting, fetching and installing packages),
487 it occurred to me that we could just divert the programs away, replace
488 them with a simple shell wrapper calling
489 "eatmydata
&nbsp;$program
&nbsp;$@
", to get the same effect.
490 Two days ago I decided to test the idea, and wrapped up a simple
491 implementation for the Debian Edu udeb.
</p
>
493 <p
>The effect was stunning. In my first test it reduced the running
494 time of the pkgsel step (installing tasks) from
64 to less than
44
495 minutes (
20 minutes shaved off the installation) on an old Dell
496 Latitude D505 machine. I am not quite sure what the optimised time
497 would have been, as I messed up the testing a bit, causing the debconf
498 priority to get low enough for two questions to pop up during
499 installation. As soon as I saw the questions I moved the installation
500 along, but do not know how long the question were holding up the
501 installation. I did some more measurements using Debian Edu Jessie,
502 and got these results. The time measured is the time stamp in
503 /var/log/syslog between the
"pkgsel: starting tasksel
" and the
504 "pkgsel: finishing up
" lines, if you want to do the same measurement
505 yourself. In Debian Edu, the tasksel dialog do not show up, and the
506 timing thus do not depend on how quickly the user handle the tasksel

555 <p
>The test is done using a netinst ISO on a USB stick, so some of the
556 time is spent downloading packages. The connection to the Internet
557 was
100Mbit/s during testing, so downloading should not be a
558 significant factor in the measurement. Download typically took a few
559 seconds to a few minutes, depending on the amount of packages being
562 <p
>The speedup is implemented by using two hooks in
563 <a href=
"https://www.debian.org/devel/debian-installer/
">Debian
564 Installer
</a
>, the pre-pkgsel.d hook to set up the diverts, and the
565 finish-install.d hook to remove the divert at the end of the
566 installation. I picked the pre-pkgsel.d hook instead of the
567 post-base-installer.d hook because I test using an ISO without the
568 eatmydata package included, and the post-base-installer.d hook in
569 Debian Edu can only operate on packages included in the ISO. The
570 negative effect of this is that I am unable to activate this
571 optimization for the kernel installation step in d-i. If the code is
572 moved to the post-base-installer.d hook, the speedup would be larger
573 for the entire installation.
</p

575 <p
>I
've implemented this in the
576 <a href=
"https://packages.qa.debian.org/debian-edu-install
">debian-edu-install
</a
>
577 git repository, and plan to provide the optimization as part of the
578 Debian Edu installation. If you want to test this yourself, you can
579 create two files in the installer (or in an udeb). One shell script
580 need do go into /usr/lib/pre-pkgsel.d/, with content like this:

651 current debian-installer coordinators find it useful enough. It also
652 depend on the side effects of the change. I
'm not aware of any, but I
653 guess we will see if the change is safe after some more testing.
654 Perhaps there is some package in Debian depending on sync() and
655 fsync() having effect? Perhaps it should go into its own udeb, to
656 allow those of us wanting to enable it to do so without affecting
659 <p
>Update
2014-
09-
24: Since a few days ago, enabling this optimization
660 will break installation of all programs using gnutls because of
661 <a href=
"https://bugs.debian.org/

662 eatmydata package in Debian will solve it.

664 <p

2014-
10-
17: The bug mentioned above is fixed in testing and
665 the optimization work again. And I have discovered that the
666 dpkg-divert trick is not really needed and implemented a slightly
667 simpler approach as part of the debian-edu-install package. See
668 tools/edu-eatmydata-install in the source package.

672 triggering on i386 made it into testing, and broke this installation

686 involved is Bernd Zeitzen, who show up on the project mailing lists
687 from time to time with interesting questions and tips on how to adjust
688 the setup. I managed to interview him this summer.

692 <p
>My name is Bernd Zeitzen and I
'm married with Hedda, a self
693 employed physiotherapist. My former profession is tool maker, but I
694 haven
't worked for
30 years in this job.
30 years ago I started to
695 support my wife and become her officeworker and a few years later the
696 administrator for a small computer network, today based on Ubuntu
697 Server (Samba, OpenVPN). For her daily work she has to use Windows
698 Desktops because the software she needs to organize her business only
699 works with Windows . :-(
</p
>
701 <p
>In
1988 we started with one PC and DOS, then I learned to use
702 Windows
98,
2000, XP, …,
8, Ubuntu, MacOSX. Today we are running a
703 Linux server with
6 Windows clients and
10 persons (teacher of
704 children with special needs, speech therapist, occupational therapist,
705 psychologist and officeworkers) using our Samba shares via OpenVPN to
706 work with the documentations of our patients.

708 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
709 project?
</strong
></p
>
711 <p
>Two years ago a friend of mine asked me, if I want to get a job in
712 his school (
<a href=
"http://www.gymnasium-harsewinkel.de/
">Gymnasium
713 Harsewinkel
</a
>). They started with Skolelinux / Debian Edu and they
714 were looking for people to give support to the teachers using the
715 software and the network and teaching the pupils increasing their
716 computer skills in optional lessons. I
'm spending
4-
6 hours a week
717 with this job.
</p
>
719 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
720 Edu?
</strong
></p
>
722 <p
>The independence.
</p
>
724 <p
>First: Every person is allowed to use, share and develop the
725 software. Even if you are poor, you are allowed to use the software
726 included in Skolelinux/Debian Edu and all the other Free Software.
</p
>
728 <p
>Second: The software runs on old machines and this gives us the
729 possibility to recycle computers, weeded out from offices. The
730 servers and desktops are running for more than two years and they are
731 working reliable.
</p
>
733 <p
>We have two servers (one tjener and one terminal server),
45
734 workstations in three classrooms and seven laptops as a mobile
735 solution for all classrooms. These machines are all booting from the
736 terminal server. In the moment we are installing
30 laptops as mobile
737 workstations. Then the pupils have the possibility to work with these
738 machines in their classrooms. Internet access is realized by a WLAN
739 router, connected to the schools network. This is all done without a
740 dedicated system administrator or a computer science teacher.

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

745 <p
>Teachers and pupils are Windows users.
&lt;Irony on
&gt; And Linux
746 isn
't cool. It
's software for freaks using the command line.
&lt;Irony
747 off
&gt; They don
't realize the stability of the system.
</p

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

751 <p
>Firefox, Thunderbird, LibreOffice, Ubuntu Server
12.04 (Samba,
752 Apache, MySQL, Joomla!, … and Skolelinux / Debian Edu)
</p
>
754 <p
><strong
>Which strategy do you believe is the right one to use to
755 get schools to use free software?
</strong
></p
>
757 <p
>In Germany we have the situation: every school is free to decide
758 which software they want to use. This decision is influenced by
759 teachers who learned to use Windows and MS Office. They buy a PC with
760 Windows preinstalled and an additional testing version of MS
761 Office. They don
't know about the possibility to use Free Software
762 instead. Another problem are the publisher of school books. They
763 develop their software, added to the school books, for Windows.

773 project
</a
> provide an instruction manual for teachers, system
774 administrators and other users that contain useful tips for setting up
775 and maintaining a Debian Edu installation. This text is about how the
776 text processing of this manual is handled in the project.
</p
>
778 <p
>One goal of the project is to provide information in the native
779 language of its users, and for this we need to handle translations.
780 But we also want to make sure each language contain the same
781 information, so for this we need a good way to keep the translations
782 in sync. And we want it to be easy for our users to improve the
783 documentation, avoiding the need to learn special formats or tools to
784 contribute, and the obvious way to do this is to make it possible to
785 edit the documentation using a web browser. We also want it to be
786 easy for translators to keep the translation up to date, and give them
787 help in figuring out what need to be translated. Here is the list of
788 tools and the process we have found trying to reach all these
791 <p
>We maintain the authoritative source of our manual in the
792 <a href=
"https://wiki.debian.org/DebianEdu/Documentation/Wheezy/
">Debian
793 wiki
</a
>, as several wiki pages written in English. It consist of one
794 front page with references to the different chapters, several pages
795 for each chapter, and finally one
"collection page
" gluing all the
796 chapters together into one large web page (aka
797 <a href=
"https://wiki.debian.org/DebianEdu/Documentation/Wheezy/AllInOne
">the
798 AllInOne page
</a
>). The AllInOne page is the one used for further
799 processing and translations. Thanks to the fact that the
800 <a href=
"http://moinmo.in/
">MoinMoin
</a
> installation on
801 wiki.debian.org support exporting pages in
802 <a href=
"http://www.docbook.org/
">the Docbook format
</a
>, we can fetch
803 the list of pages to export using the raw version of the AllInOne
804 page, loop over each of them to generate a Docbook XML version of the
805 manual. This process also download images and transform image
806 references to use the locally downloaded images. The generated
807 Docbook XML files are slightly broken, so some post-processing is done
808 using the
<tt
>documentation/scripts/get_manual
</tt
> program, and the
809 result is a nice Docbook XML file (debian-edu-wheezy-manual.xml) and
810 a handfull of images. The XML file can now be used to generate PDF, HTML
811 and epub versions of the English manual. This is the basic step of
812 our process, making PDF (using dblatex), HTML (using xsltproc) and
813 epub (using dbtoepub) version from Docbook XML, and the resulting files
814 are placed in the debian-edu-doc-en binary package.
</p
>
816 <p
>But English documentation is not enough for us. We want translated
817 documentation too, and we want to make it easy for translators to
818 track the English original. For this we use the
819 <a href=
"http://packages.qa.debian.org/p/poxml.html
">poxml
</a
> package,
820 which allow us to transform the English Docbook XML file into a
821 translation file (a .pot file), usable with the normal gettext based
822 translation tools used by those translating free software. The pot
823 file is used to create and maintain translation files (several .po
824 files), which the translations update with the native language
825 translations of all titles, paragraphs and blocks of text in the
826 original. The next step is combining the original English Docbook XML
827 and the translation file (say debian-edu-wheezy-manual.nb.po), to
828 create a translated Docbook XML file (in this case
829 debian-edu-wheezy-manual.nb.xml). This translated (or partly
830 translated, if the translation is not complete) Docbook XML file can
831 then be used like the original to create a PDF, HTML and epub version
832 of the documentation.
</p
>
834 <p
>The translators use different tools to edit the .po files. We
836 <a href=
"http://www.kde.org/applications/development/lokalize/
">lokalize
</a
>,
837 while some use emacs and vi, others can use web based editors like
838 <a href=
"http://pootle.translatehouse.org/
">Poodle
</a
> or
839 <a href=
"https://www.transifex.com/
">Transifex
</a
>. All we care about
840 is where the .po file end up, in our git repository. Updated
841 translations can either be committed directly to git, or submitted as
842 <a href=
"https://bugs.debian.org/src:debian-edu-doc
">bug reports
843 against the debian-edu-doc package
</a
>.
</p
>
845 <p
>One challenge is images, which both might need to be translated (if
846 they show translated user applications), and are needed in different
847 formats when creating PDF and HTML versions (epub is a HTML version in
848 this regard). For this we transform the original PNG images to the
849 needed density and format during build, and have a way to provide
850 translated images by storing translated versions in
851 images/$LANGUAGECODE/. I am a bit unsure about the details here. The
852 package maintainers know more.
</p
>
854 <p
>If you wonder what the result look like, we provide
855 <a href=

">the content
856 of the documentation packages on the web

27 years old (
1986 generation) and I
887 live in Barcelona, Spain. I
've got a strong business background and I
888 work as a patrimony manager and as a real estate agent. Additionally,
889 I

893 ago and have recently switched to Debian seeking rock solid stability
894 and as a necessary step to gain expertise.

901 project?
</strong

903 <p
>I discovered the
<a href=
"http://www.ltsp.org/
">LTSP
</a
> advantages
904 with
"Ubuntu
12.04 alternate install
" and after a year of use I
905 started looking for an alternative. Even though I highly value and
906 respect the Ubuntu project, I thought it was necessary for me to
907 change to a more robust and stable alternative. As far as I was using
908 Debian on my personal laptop I thought it would be fine to install
909 Debian and configure an LTSP server myself. Surprised, I discovered
910 that the Debian project also supported a kind of Edubuntu equivalent,
911 and after having some pain I obtained a Debian Edu network up and
912 running. I just loved it.
</p
>
914 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
915 Edu?
</strong
></p
>
917 <p
>I found a main advantage in that, once you know
"the tips and
918 tricks
", a new installation just works out of the box. It
's the most
919 complete alternative I
've found to create an LTSP network. All the
920 other distributions seems to be made of plastic, Debian Edu seems to
921 be made of steel.

923 <p

</strong

926 <p
>I found two main disadvantages.
</p

928 <p
>I
'm not an expert but I
've got notions and I had to spent a considerable
929 amount of time trying to bring up a standard network topology. I
'm quite
930 stubborn and I just worked until I did but I
'm sure many people with few
931 resources (not big schools, but academies for example) would have switched
932 or dropped.
</p
>
934 <p
>It
's amazing how such a complex system like Debian Edu has achieved
935 this out-of-the-box state. Even though tweaking without breaking gets
936 more difficult, as more factors have to be considered. This can
937 discourage many people too.
</p

939 <p

</strong

941 <p
>I use Debian, Firefox, Okular, Inkscape, LibreOffice and
942 Virtualbox.
</p

945 <p
><strong
>Which strategy do you believe is the right one to use to
946 get schools to use free software?
</strong
></p
>
948 <p
>I don
't think there is a need for a particular strategy. The free
949 attribute in both
"freedom
" and
"no price
" meanings is what will
950 really bring free software to schools. In my experience I can think of
951 the
<a href=
"http://www.r-project.org/

" statistical language
</a
>; a
952 few years a ago was an extremely nerd tool for university people.
953 Today it
's being increasingly used to teach statistics at many
954 different level of studies. I believe free and open software will
955 increasingly gain popularity, but I
'm sure schools will be one of the
956 first scenarios where this will happen.

965 <description><p
>On larger sites, it is useful to use a dedicated storage server for
966 storing user home directories and data. The design for handling this
967 in
<a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>, is
968 to update the automount rules in LDAP and let the automount daemon on
969 the clients take care of the rest. I was reminded about the need to
970 document this better when one of the customers of
971 <a href=
"http://www.slxdrift.no/
">Skolelinux Drift AS
</a
>, where I am
972 on the board of directors, asked about how to do this. The steps to
973 get this working are the following:
</p
>
977 <li
>Add new storage server in DNS. I use nas-server.intern as the
978 example host here.
</li
>
980 <li
>Add automoun LDAP information about this server in LDAP, to allow
981 all clients to automatically mount it on reqeust.
</li
>
983 <li
>Add the relevant entries in tjener.intern:/etc/fstab, because
984 tjener.intern do not use automount to avoid mounting loops.
</li
>
986 </ol
></p
>
988 <p
>DNS entries are added in GOsa², and not described here. Follow the
989 <a href=
"https://wiki.debian.org/DebianEdu/Documentation/Wheezy/GettingStarted
">instructions
990 in the manual
</a
> (Machine Management with GOsa² in section Getting
993 <p
>Ensure that the NFS export points on the server are exported to the
994 relevant subnets or machines:

997 root@tjener:~# showmount -e nas-server
998 Export list for nas-server:
1001 </pre

>
1003 <p
>Here everything on the backbone network is granted access to the
1004 /storage export. With NFSv3 it is slightly better to limit it to
1005 netgroup membership or single IP addresses to have some limits on the
1006 NFS access.
</p
>
1008 <p
>The next step is to update LDAP. This can not be done using GOsa²,
1009 because it lack a module for automount. Instead, use ldapvi and add
1010 the required LDAP objects using an editor.

></p
>
1016 <p
>When the editor show up, add the following LDAP objects at the
1017 bottom of the document. The
"/
&" part in the last LDAP object is a
1018 wild card matching everything the nas-server exports, removing the
1019 need to list individual mount points in LDAP.

1042 <p

1056 was able to get an interview with a newcomer in the project who showed
1057 up on the IRC channel a few weeks ago to let us know about his
1058 successful installation of Debian Edu Wheezy in his School. Say hello
1059 to
<a href=

>
1064 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
1066 <p
>I am a
23 year-old student from Germany who has spent half of his
1067 life with open source. In
"real life
", I am, as already mentioned, a
1068 student in the fields of Computer Science, Electrical Engineering,
1069 Information Technologies and Anglistics. Due to my (only partially
1070 voluntary) huge engagement in the open source world, these things are
1071 a bit vacant right now however.
</p
>
1073 <p
>I also have been working as a project teacher at a Gymasnium
1074 (public school) for various years now. I took up that work some time
1075 around
2005 when still attending that school myself and have continued
1076 it until today. I also had been running the (kind of very advanced)
1077 network of that school together with a team of very interested and
1078 talented students in the age of
11 to
15 years, who took the chance to
1079 learn a lot about open source and networking before I left the school
1080 to help building another school
's informational education concept from
1083 <p
>That said, one might see me as a kind of
"glue
" between school kids
1084 and the elderly of teachers as well as between the open source
1085 ecosystem and the (even more complex) educational ecosystem.
</p
>
1087 <p
>When I am not busy with open source or education, I like Geocaching
1088 and cycling.
</p
>
1090 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
1091 project?
</strong
></p
>
1093 <p
>I think that happened some time around
2009 when I first attended
1094 <a href=
"http://www.froscon.org
">FrOSCon
</a
> and visited the project
1095 booth. I think I wasn
't too interested back then because I used to
1096 have an attitude of disliking software that does too much stuff on its
1097 own. Maybe I was too inexperienced to realise the upsides of an
1098 "out-of-the-box
" solution ;).
</p
>
1100 <p
>The first time I actively talked to Skolelinux people was at
1101 <a href=
"http://www.openrheinruhr.de
">OpenRheinRuhr
</a
> 2011 when the
1102 BiscuIT project, a home-grewn software used by my school for various
1103 really cool things from timetables and class contact lists to lunch
1104 ordering, student ID card printing and project elections first got to
1105 a stage where it could have been published. I asked the Skolelinux
1106 guys running the booth if the project were interested in it and gave a
1107 small demonstration, but there wasn
't any real feedback and the guys
1108 seemed rather uninterested.
</p
>
1110 <p
>After I left the school where I developed the software, it got
1111 mostly lost, but I am now reimplementing it for my new school. I have
1112 reusability and compatibility in mind, and I hop there will be a new
1113 basis for contributing it to the Skolelinux project ;)!
</p
>
1115 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
1116 Edu?
</strong
></p
>
1118 <p
>The most important advantage seems to be that it
"just
1119 works
". After overcoming some minor (but still very annoying) glitches
1120 in the installer, I got a fully functional, working school network,
1121 without the month-long hassle I experienced when setting all that up
1122 from scratch in earlier years. And above that, it rocked - I didn
't
1123 have any real hardware at hand, because the school was just founded
1124 and has no money whatsoever, so I installed a combined server (main
1125 server, terminal services and workstation) in a VM on my personal
1126 notebook, bridging the LTSP network interface to the ethernet port,
1127 and then PXE-booted the Windows notebooks that were lying around from
1128 it. I could use
8 clients without any performance issues, by using a
1129 tiny little VM on a tiny little notebook. I think that
's enough to say
1130 that it rocks!
</p
>
1132 <p
>Secondly, there are marketing reasons. Life
's bad, and so no
1133 politician will ever permit a setup described as
"Debian, an universal
1134 operating system, with some really cool educational tools
" while they
1135 will be jsut fine with
"Skolelinux, a single-purpose solution for your
1136 school network
", even if both turn out to be the very same thing (yes,
1137 this is unfair towards the Skolelinux project, and must not be taken
1138 too seriously - you get the idea, anyway).
</p
>
1140 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
1141 Edu?
</strong
></p
>
1143 <p
>I have not been involved with Skolelinux long enough to really
1144 answer this question in a fair way. Thus, please allow me to put it in
1145 other words:
"What do you expect from Skolelinux to keep liking it?
" I
1146 can list a few points about that:
</p
>
1150 <li
>always strive to get all things integrated into Debian upstream
1151 <li
>be open to discussion about changes and the like, even with newcomers
1152 <li
>be helpful at being helpful ;)
1156 <p
>I
'm really sorry I cannot say much more about that :(!
</p
>
1158 <p
><strong
>Which free software do you use daily?
</strong
></p
>
1160 <p
>First of all, all software I use is free and open. I have abandoned
1161 all non-free software (except for firmware on my darned phone) this
1164 <p
>I run Debian GNU/Linux on all PC systems I use. On that, I mostly
1165 run text tools. I use
1166 <a href=
"https://www.mirbsd.org/mksh.htm
">mksh
</a
> as shell,
1167 <a href=
"https://www.mirbsd.org/jupp.htm
">jupp
</a
> as very advanced
1168 text editor (I even got the developer to help me write a script/macro
1169 based full-featured student management software with the two),
1170 <a href=
"http://mcabber.com/
">mcabber
</a
> for XMPP and
1171 <a href=
"http://www.irssi.org/
">irssi
</a
> for IRC. For that overly
1172 coloured world called the WWW, I use
1173 <a href=
"https://www.mozilla.org/en-US/firefox/new/
">Iceweasel
1174 (Firefox)
</a
>. Oh, and
<a href=
"http://www.mutt.org/
">mutt
</a
> for
1177 <p
>However, while I am personally aware of the fact that text tools
1178 are more efficient and powerful than anything else, I also use (or at
1179 least operate) some tools that are suitable to bring open source to
1180 kids. One of these things is
<a href=
"http://jappix.org/
">Jappix
</a
>,
1181 which I already introduced to some kids even before they got aware of
1182 Facebook, making them see for themselves that they do not need
1183 Facebook now ;).
</p
>
1185 <p
><strong
>Which strategy do you believe is the right one to use to
1186 get schools to use free software?
</strong
></p
>
1188 <p
>Well, that
's a two-sided thing. One side is what I believe, and one
1189 side is what I have experienced.
</p
>
1191 <p
>I believe that the right strategy is showing them the benefits. But
1192 that won
't work out as long as the acceptance of free alternatives
1193 grows globally. What I mean is that if all the kids are almost forced
1194 to use Windows, Facebook, Skype, you name it at home, they will not
1195 see why they would want to use alternatives at school. I have seen
1196 students take seat in front of a fully-functional, modern Debian
1197 desktop that could do anything their Windows at home could do, and
1198 they jsut refused to use it because
"Linux sucks
". It is something
1199 that makes the council of our city spend around
600000 € to buy
1200 software - not including hardware, mind you - for operating school
1201 networks, and for installing a system that, as has been proved, does
1202 not work. For those of you readers who are good at maths, have you
1203 already found out how many lives could have been saved with that money
1204 if we had instead used it to bring education to parts of the world
1205 that need it? I have, and found it to be nothing less dramatic than
1206 plain criminal.
</p
>
1208 <p
>That said, the only feasible way appears to be the bottom up
1209 method. We have to bring free software to kids and parents. I have
1210 founded an association named
1211 <a href=
"https://www.teckids.org
">Teckids
</a
> here in Germany that does
1212 just that. We organise several events for kids and adolescents in the
1213 area of free and open source software, for example the
1214 <a href=
"http://kids.froscon.org
">FrogLabs
</a
>, which share staff with
1215 Teckids and are the youth programme of
1216 <a href=
"http://www.froscon.org
">the Free and Open Source Software
1217 Conference (FrOSCon)
</a
>. We do a lot more than most other conferences
1218 - this year, we first offered the FrogLabs as a holiday camp for kids
1219 aged
10 to
16. It was a huge success, with approx.
30 kids taking part
1220 and learning with and about free software through a whole weekend. All
1221 of us had a lot of fun, and the results were really exciting.
</p
>
1223 <p
>Apart from that, we are preparing a campaign that is supposed to bring
1224 the message of free alternatives to stuff kids use every day to them and
1225 their parents, e.g. the use of Jabber / Jappix instead of Facebook and
1226 Skype. To make that possible, we are planning to get together a team of
1227 clever kids who understand very well what their peers need and can bring
1228 it across to them. So we will have a peer-driven network of adolescents
1229 who teach each other and collect feedback from the community of minors.
1230 We then take that feedback and our own experience to work closely with
1231 open source projects, such as Skolelinux or Jappix, at improving their
1232 software in a way that makes it more and more attractive for the target
1233 group. At least I hope that we will have good cooperation with
1234 Skolelinux in the future ;)!
</p
>
1236 <p
>So in conclusion, what I believe is that, if it weren
't for the world
1237 being so bad, it should be very clear to the political decision makers
1238 that the only way to go nowadays is free software for various reasons,
1239 but I have learnt that the only way that seems to work is bottom up.
</p
>
1243 > * Who should be interviewed with this questions in the future?
1245 That
's probably the hardest question of them all, as I do not know the
1246 community. However, I would be willing to do the following:
1248 <li
>Run an interview with a German headteacher who is very open to
1249 free software, and also prefers it, but cannot really use it because
1250 of the decision makers above;
1251 <li
>Run interviews with some kids, both with and without previous
1252 knowledge about free software
1254 If that is wanted, just let me know ;).

1314 Edu?
</strong
></p
>
1317 <li
>Skolelinux is - as we had to learn - not easily upgradable to
1318 the next version. Opposed to its genuine Debian base, upgrading to
1319 a new version means a full new installation from scratch to get it
1320 working again reliably.
1322 <li
>Skolelinux is based on Debian/stable, and therefore always a
1323 little outdated in terms of program versions compared to Edubuntu or
1324 similar educational Linux distros, which rather use Debian/testing
1327 <li
>Skolelinux has some very self-opinionated and stubborn default
1328 configuration which in my opinion adds unnecessary complexity and is
1329 not always suitable for a schools needs, the preset network
1330 configuration is actually a core definition feature of Skolelinux
1331 and not easy to change, so schools sometimes have to change their
1332 network configuration to make it
"Skolelinux-compatible
".
1334 <li
>Some proposed extensions, which were made available as
1335 contribution, like secure examination mode and lecture material
1336 distribution and collection, were not accepted into the mainline
1337 Skolelinux development and are now not easy to maintain in the
1338 future because of Skolelinux somewhat undeterministic update
1341 <li
>Skolelinux has only a very tiny number of base developers
1342 compared to Debian.
</li
>
1346 <p
>For these reasons and experience from our project, I would now
1347 rather consider using plain Debian for schools next time, until
1348 Skolelinux is more closely integrated into Debian and becomes
1349 upgradeable without reinstallation.

1353 <p
>GNU/Linux with LXDE desktop, bash for interactive dialog and

1358 <p
><strong
>Which strategy do you believe is the right one to use to
1359 get schools to use free software?
</strong

1361 <p
>Strong arguments are
</p
>
1365 <li
>Knowledge is free, and so should be methods and tools for
1366 teaching and learning.
</li
>
1368 <li
>Students can learn with and use the same software at school, at
1369 home, and at their working place without running into license or
1370 conversion problems.
</li
>
1372 <li
>Closed source or proprietary software hides knowledge rather
1373 than exposing it, and proprietary software vendors try to bind
1374 customers to certain products. But teachers need to teach
1375 science, not products.

>About Debian Edu and Skolelinux
</p
>
1510 <p
>Debian Edu, also known as Skolelinux, is a Linux distribution based
1511 on Debian providing an out-of-the box environment of a completely
1512 configured school network. Immediately after installation a school
1513 server running all services needed for a school network is set up just
1514 waiting for users and machines being added via GOsa², a comfortable
1515 Web-UI. A netbooting environment is prepared using PXE, so after
1516 initial installation of the main server from CD or USB stick all other
1517 machines can be installed via the network. The provided school server
1518 provides LDAP database and Kerberos authentication service,
1519 centralized home directories, DHCP server, web proxy and many other
1520 services. The desktop contains more than
60 educational software
1521 packages and more are available from the Debian archive, and schools
1522 can choose between KDE, Gnome, LXDE and Xfce desktop environment.
</p
>
1524 <p
>This is the seventh test release based on Debian Wheezy. Basically
1525 this is an updated and slightly improved version compared to the
1526 Squeeze release.
</p
>
1528 <p
>Notes for upgrades from Alpha Prereleases
</p
>
1530 <p
>Alpha based installations should reinstall or downgrade the
1531 versions of gosa and libpam-mklocaluser to the ones used in this beta
1532 release. Both alpha and beta0 based installations should reinstall or
1533 deal with gosa.conf manually; there are two options: (
1) Keep
1534 gosa.conf and edit this file as outlined on the mailing list. (
2)
1535 Accept the new version of gosa.conf and replace both contained admin
1536 password placeholders with the password hashes found in the old one
1537 (backup copy!). In both cases all users need to change their password
1538 to make sure a password is set for CIFS access to their home
1539 directory.

1726 <li
>Switched roaming workstation profiles from wicd to network-manager
1727 for network configuration, as wicd didn

1728 <li
>Changed version numbers of patched gosa and libpam-mklocaluser

">Debian Edu, also known as
1851 Skolelinux
</a
>, is a Linux distribution based on Debian providing an
1852 out-of-the box environment of a completely configured school
1853 network. Immediately after installation a school server running all
1854 services needed for a school network is set up just waiting for users
1855 and machines being added via GOsa², a comfortable Web-UI. A netbooting
1856 environment is prepared using PXE, so after initial installation of
1857 the main server from CD, DVD or USB stick all other machines can be
1858 installed via the network. The provided school server provides LDAP
1859 database and Kerberos authentication service, centralized home

1869 Squeeze release.
</p

1871 <p
><strong
>Software updates
</strong
></p
>
1873 <li
>Dropped ispell dictionaries from our default installation.
</li
>
1874 <li
>Dropped menu-xdg from the KDE desktop option, to drop the Debian
1875 submenu. It was not included with Gnome, LXDE or Xfce, so this
1876 brings KDE in line with the others.
</li
>
1877 <li
>Dropped xdrawchem, xjig and xsok from our default installation as
1878 they don
't have a desktop menu entry and thus won
't show up in the
1879 menu now that menu-xdg was removed.
</li
>
1880 <li
>Removed the killer system to kill left behind processes on
1881 multi-user machines, as it was no longer able to understand when a
1882 X display was in use and killed the processes of the active users
1884 <li
>Dropped the golearn (from goplay) package as the debtags in wheezy
1885 are too few to make the package useful.

>
1887 <p
><strong
>Other changes
</strong
></p

1889 <li
>Updated artwork matching http://wiki.debian.org/DebianArt/Themes/Joy
1890 <li
>Multi-arch i386/amd64 USB stick ISO available.
</li
>
1891 <li
>Got rid of ispell/wordlist related debconf questions that showed
1892 up for some language options.
</li
>
1893 <li
>Switched to using http.debian.net as APT source by default.
</li
>
1894 <li
>Fixed proxy configuration on Main Server installations.
</li
>
1895 <li
>Changed LTSP setup to ask dpkg to use force-unsafe-io the same way
1896 d-i is doing it.
</li
>
1897 <li
>Made sure root and user passwords were not left behind in the
1898 debconf database after installation on Main Server installations.
</li
>
1899 <li
>Made Roaming Workstation dynamic setup more robust and added draft
1900 script setup-ad-client to hook a Roaming Workstation up to a
1901 Active Directory server instead of a Debian Edu Main Server.
</li
>
1902 <li
>Update system to install needed firmware packages during
1903 installation, to work properly in Wheezy.
</li
>
1904 <li
>Update system to handle hardware quirks (debian-edu-hwsetup).
</li
>
1905 <li
>Corrected PXE installation setup to properly pass selected desktop
1906 and keymap settings to PXE installation clients.
</li
>
1907 <li
>LTSP diskless workstations use sshfs by default, allowing them to
1908 work without adding them to DNS and NIS netgroups for NFS access.

>In the
<a href=
"http://www.skolelinux.org/
">Debian Edu /
1950 Skolelinux
</a
> project, we include a post-installation test suite,
1951 which check that services are running, working, and return the
1952 expected results. It runs automatically just after the first boot on
1953 test installations (using test ISOs), but not on production
1954 installations (using non-test ISOs). It test that the LDAP service is
1955 operating, Kerberos is responding, DNS is replying, file systems are
1956 online resizable, etc, etc. And it check that the PXE service is
1957 configured, which is the topic of this post.
</p
>
1959 <p
>The last week I
've fixed the DVD and USB stick ISOs for our Debian
1960 Edu Wheezy release. These ISOs are supposed to be able to install a
1961 complete system without any Internet connection, but for that to
1962 happen all the needed packages need to be on them. Thanks to our test
1963 suite, I discovered that we had forgotten to adjust our PXE setup to
1964 cope with the new names and paths used by the netboot d-i packages.
1965 When Internet connectivity was available, the installer fall back to
1966 using wget to fetch d-i boot images, but when offline it require
1967 working packages to get it working. And the packages changed name
1968 from debian-installer-
6.0-netboot-$arch to
1969 debian-installer-
7.0-netboot-$arch, we no longer pulled in the
1970 packages during installation. Without our test suite, I suspect we
1971 would never have discovered this before release. Now it is fixed
1972 right after we got the ISOs operational.
</p
>
1974 <p
>Another by-product of the test suite is that we can ask system
1975 administrators with problems getting Debian Edu to work, to run the
1976 test suite using
<tt
>/usr/sbin/debian-edu-test-install
</tt
> and see if
1977 any errors are detected. This usually pinpoint the subsystem causing
1978 the problem.

1998 #debian-edu

1999 worked. We answered as good as we could, and even convinced him to
2000 help us with translations. And today I managed to get an interview
2001 with him, to learn more about him.

2005 <p
>I
'm a
25 year old free software enthusiast, living in Romania,
2006 which is also my country of origin. Back in
2009, at a New Year
's Eve
2007 party, I had a very nice
<strike
>beer
</strike
> discussion with a
2008 friend, when we realized we have no organised Debian community in our
2009 country. A few days later, we put together the infrastructure for such
2010 community and even gathered a nice Debian-ish crowd. Since then, I
2011 began my quest as a free software hacker and activist and I am
2012 constantly trying to cover as much ground as possible on that
2015 <p
>A few years ago I founded a small web development company, which
2016 provided me the flexible schedule I needed so much for my
2017 activities. For the last
13 months, I have been the Technical Director
2018 of
<a href=
"http://ceata.org/
">Fundația Ceata
</a
>, which is a free
2019 software activist organisation endorsed by the FSF and the FSFE, and
2020 the only one we have in our country.
</p

2022 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
2023 project?
</strong
></p
>
2025 <p
>The idea of participating in the Debian Edu project was a surprise
2026 even to me, since I never used it before I began getting involved in
2027 it. This year I had a great opportunity to deliver a talk on
2028 educational software, and I knew immediately where to look. It was a
2029 love at first sight, since I was previously involved with some of the
2030 technologies the project incorporates, and I rapidly found a lot of
2031 ways to contribute.
</p
>
2033 <p
>My first contributions consisted in translating the installer and
2034 configuration dialogs, then I found some bugs to squash (I still
2035 haven
't fixed them yet though), and I even got my eyes on some other
2036 areas where I can prove myself helpful. Since the appetite for free
2037 software in my country is pretty low, I
'll be happy to be the first
2038 one around here advocating for the project
's adoption in educational
2039 environments, and maybe even get my hands dirty in creating a flavour
2040 for our own needs. I am not used to make very advanced plannings, so
2041 from now on, time will tell what I
'll be doing next, but I think I
2042 have a pretty consistent starting point.

><strong
>What do you see as the advantages of Skolelinux/Debian
2045 Edu?
</strong
></p
>
2047 <p
>Not a long time ago, I was in the position of configuring and
2048 maintaining a LDAP server on some Debian derivative, and I must say it
2049 took me a while. A long time ago, I was maintaining a bigger
2050 Samba-powered infrastructure, and I must say I spent quite a lot of
2051 time on it. I have similar stories about many of the services included
2052 with Skolelinux, and the main advantage I see about it is the
2053 out-of-the box availability of them, making it quite competitive when
2054 it comes to managing a school
's network, for example.
</p
>
2056 <p
>Of course, there is more to say about Skolelinux than the
2057 availability of the software included, its flexibility in various
2058 scenarios is something I can
't wait to experiment
"into the wild
" (I
2059 only played with virtual machines so far). And I am sure there is a
2060 lot more I haven
't discovered yet about it, being so new within the

>As usual, when it comes to Debian Blends, I see as the biggest
2067 disadvantage the lack of a numerous team dedicated to the
2068 project. Every day I see the same names in the changelogs, and I have
2069 a constantly fear of the bus factor in this story. I
'd like to see
2070 Debian Edu advertised more as an entry point into the Debian
2071 ecosystem, especially amongst newcomers and students. IMHO there are a
2072 lot low-hanging fruits in terms of bug squashing, and enough
2073 opportunities to get the feeling of the Debian Project
's dynamics. Not
2074 to mention it
's a very fun blend to work on!

2076 <p

2077 with the main Debian release and documentation. This is common though

2087 <a href=

2104 <li

2108 <li

"right one

2109 be useful to have some success stories published somewhere, so
2110 other can get some inspiration from them (I know I
'd promote
2113 <li

2114 lectures can do magical things if they encounter at least one
2115 person interested. Who knows who that person might be? ;-)

2119 <p
>I also see some problems in getting Skolelinux into schools; for
2120 example, in our country we have a great deal of corruption issues, so
2121 it might be hard(er) to fight against proprietary solutions. Also,

>There is a certain cross-over between the
2133 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
2134 project
</a
> and
<a href=
"http://www.edubuntu.org/
">the Edubuntu
2135 project
</a
>, and for example the LTSP packages in Debian are a joint
2136 effort between the projects. One person with a foot in both camps is
2137 Jonathan Carter, which I am now happy to present to you.
</p
>
2139 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
2141 <p
>I
'm a South-African free software geek who lives in Cape Town. My
2142 days vary quite a bit since I
'm involved in too many things. As I
'm
2143 getting older I
'm learning how to focus a bit more :)
</p
>
2145 <p
>I
'm also an Edubuntu contributor and I love when there are
2146 opportunities for the Edubuntu and Debian Edu projects to benefit from
2147 each other.
</p
>
2149 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
2150 project?
</strong
></p
>
2152 <p
>I
've been somewhat familiar with the project before, but I think my
2153 first direct exposure to the project was when I met Petter
2154 [Reinholdtsen] and Knut [Yrvin] at the Edubuntu summit in
2005 in
2155 London. They provided great feedback that helped the bootstrapping of
2156 Edubuntu. Back then Edubuntu (and even Ubuntu) was still very new and
2157 it was great getting input from people who have been around longer. I
2158 was also still very excitable and said yes to everything and to this
2159 day I have a big todo list backlog that I
'm catching up with. I think
2160 over the years the relationship between Edubuntu and Debian-Edu has
2161 been gradually improving, although I think there
's a lot that we could
2162 still improve on in terms of working together on packages. I
'm sure
2163 we
'll get there one day.
</p
>
2165 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
2166 Edu?
</strong
></p
>
2168 <p
>Debian itself already has so many advantages. I could go on about
2169 it for pages, but in essence I love that it
's a very honest project
2170 that puts its users first with no hidden agendas and also produces
2171 very high quality work.
</p
>
2173 <p
>I think the advantage of Debian Edu is that it makes many common
2174 set-up tasks simpler so that administrators can get up and running
2175 with a lot less effort and frustration. At the same time I think it
2176 helps to standardise installations in schools so that it
's easier for
2177 community members and commercial suppliers to support.
</p
>
2179 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
2180 Edu?
</strong
></p
>
2182 <p
>I had to re-type this one a few times because I
'm trying to
2183 separate
"disadvantages
" from
"areas that need improvement
" (which is
2184 what I originally rambled on about)
</p
>
2186 <p
>The biggest disadvantage I can think of is lack of manpower. The
2187 project could do so much more if there were more good contributors. I
2188 think some of the problems are external too. Free software and free
2189 content in education is a no-brainer but it takes some time to catch
2190 on. When you
've been working with the same proprietary eco-system for
2191 years and have gotten used to it, it can be hard to adjust to some
2192 concepts in the free software world. It would be nice if there were
2193 more Debian Edu consultants across the world. I
'd love to be one
2194 myself but I
'm already so over-committed that it
's just not possible
2195 currently.
</p
>
2197 <p
>I think the best short-term solution to that large-scale problem is
2198 for schools to be pro-active and share their experiences and grow
2199 their skills in-house. I
'm often saddened to see how much money
2200 educational institutions spend on
3rd party solutions that they don
't
2201 have access to after the service has ended and they could
've gotten so
2202 much more value otherwise by being more self-sustainable and
2203 autonomous.
</p
>
2205 <p
><strong
>Which free software do you use daily?
</strong
></p
>
2207 <p
>My main laptop dual-boots between Debian and Windows
7. I was
2208 Windows free for years but started dual-booting again last year for
2209 some games which help me focus and relax (Starcraft II in
2210 particular). Gaming support on Linux is improving in leaps and bounds
2211 so I suppose I
'll soon be able to regain that disk space :)
</p
>
2213 <p
>Besides that I rely on Icedove, Chromium, Terminator, Byobu, irssi,
2214 git, Tomboy, KVM, VLC and LibreOffice. Recently I
've been torn on
2215 which desktop environment I like and I
'm taking some refuge in Xfce
2216 while I figure that out. I like tools that keep things simple. I enjoy
2217 Python and shell scripting. I went to an Arduino workshop recently and
2218 it was awesome seeing how easy and simple the IDE software was to get
2219 up and running in Debian compared to the users running Windows and OS
2222 <p
>I also use mc which some people frown upon slightly. I got used to
2223 using Norton Commander in the early
90's and it stuck (I think the
2224 people who sneer at it is just jealous that they don
't know how to use
2227 <p
><strong
>Which strategy do you believe is the right one to use to
2228 get schools to use free software?
</strong
></p
>
2230 <p
>I think trying to force it is unproductive. I also think that in
2231 many cases it
's appropriate for schools to use non-free systems and I
2232 don
't think that there
's any particular moral or ethical problem with
2235 <p
>I do think though that free software can already solve so so many
2236 problems in educational institutions and it
's just a shame not taking
2237 advantage of that.
</p
>
2239 <p
>I also think that some curricula need serious review. For example,
2240 some areas of the world rely heavily on very specific versions of MS
2241 Office, teaching students to parrot menu items instead of learning the
2242 general concepts. I think that
's very unproductive because firstly, MS
2243 Office
's interface changes drastically every few years and on top of
2244 that it also locks in a generation to a product that might not be the
2245 best solution for them.
</p
>
2247 <p
>To answer your question, I believe that the right strategy is to
2248 educate and inform, giving someone the information they require to
2249 make a decision that would work for them.

">Debian Edu, also known as
2270 Skolelinux
</a
>, is a Linux distribution based on Debian providing an
2271 out-of-the box environment of a completely configured school
2272 network. Immediately after installation a school server running all
2273 services needed for a school network is set up just waiting for users
2274 and machines being added via GOsa², a comfortable Web-UI. A netbooting
2275 environment is prepared using PXE, so after initial installation of
2276 the main server from CD, DVD or USB stick all other machines can be
2277 installed via the network. The provided school server provides LDAP
2278 database and Kerberos authentication service, centralized home
2279 directories, DHCP server, web proxy and many other services. The

>What do you see as the disadvantages of Skolelinux / Debian
2471 Edu?
</strong
></p

2473 <p
>Maybe the lack of manpower to do lobbying on the
2474 project. Sometimes, people who need to take decisions concerning IT do
2475 not have all the elements to evaluate properly free software
2476 solutions. The fact that support by a company may be difficult to find
2477 is probably a problem if the school does not have IT personnel.
</p

2479 <p
>One can find support from a company by looking at
2480 <a href=
"http://wiki.debian.org/DebianEdu/Help/ProfessionalHelp
">the
2481 wiki dokumentation
</a
>, where some countries already have a number of
2482 companies providing support for Debian Edu, like Germany or
2483 Norway. This list is easy to find readily from the manual. However,
2484 for other countries, like France, the list is empty. I guess that
2485 consultants proposing support for Debian would be able to provide some
2486 support for Debian Edu as well.

2488 <p
><strong
>Which free software do you use daily?
</strong
></p

2490 <p
>I am using the KDE Plasma Desktop. But the pieces of software I use
2491 most runs in a terminal: Mutt and OfflineIMAP for emails, latex for
2492 scientific documents, mpd for music. VIM is my editor of choice. I am
2493 also using the mathematical software
2494 <a href=
"http://www.scilab.org/en/scilab/about
">Scilab
</a
> and
2495 <a href=
"http://www.sagemath.org/index.html
">Sage
</a

2496 source as not completely packaged for Debian, yet).
2498 <p

2502 <p
>I do not have any
"nice
" recommendations for statistics. At our
2503 university, we use both
<a href=
"http://www.r-project.org/

2504 Scilab to teach statistics and probabilistic simulations. For
2505 geometry, there are nice programs:

2510 <a href=
"http://edu.kde.org/applications/all/kig

2513 <li
><a href=

2514 to discover symmetry groups (the so-called wallpapers and frieze

2554 tag them all using debtags use::learning and role::program, and using
2555 the debtags I was happy to be able to create a collage of the

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

2701 <p
>Jeg heter Nirosan Thiyagalingam. Jeg er
24 år og studerer
2702 dataingeniør studiet ved Høgskolen i Sør Trøndelag. Interessen for
2703 data har siden ung alder vært tilstede og jeg har i tillegg alltid
2704 vært glad i å lære nye ting. Med teknologi som endres svært hurtig er
2705 det alltid noe nytt å lære. Noe som igjen har gjort det svært
2706 interessant å følge med på utviklingen. Jeg valgte dataingeniør
2707 studiet grunnet ønske om å lære enda mer om programmering og utvikling
2708 av store systemer.
</p
>
2710 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
2712 <p
>Skolelinux prosjektet hørte jeg først om i media. Men det var først
2713 når jeg skulle velge bacheloroppgave at jeg fattet mer interesse for
2714 prosjektet. Et enkelt søk på nettet førte meg til skolelinux sine
2715 hjemmesider. Informasjonen jeg fant der gjorde meg enda nysgjerrig og
2716 jeg valgte derfor en oppgave som gikk ut på å få en
2717 <a href=
"http://www.raspberrypi.org
">Raspberry PI
</a
>. Altså en
2718 ultra-billig datamaskin til å kjøre Debian Edu på lik linje med
2719 vanlige datamaskiner. I løpet av prosjektet ble det gjort mye
2720 forskning på nettet. Det var mye jeg måtte forstå rundt hvordan
2721 operativsystemet Linux fungerte før jeg kunne angripe
2722 problemet. Prøvde først å finne ut hvordan man kunne transformere en
2723 vanlig installasjon av Skolelinux til Raspberry PI, men dette var
2724 altfor vanskelig å jeg endte opp med mer spørsmål enn svar. Det ble
2725 videre opprettet kontakt med Skolelinux utviklere på IRC der jeg fikk
2726 diskutert hvilken retning jeg burde gå for å få til en fullverdig
2727 løsning. Det ble bestemt at jeg skulle gå for å først installere
2728 <a href=
"http://www.raspbian.org/
">Raspian
</a
>. Dette er et
2729 operativsystem basert på Debian spesiallaget for Raspberry Pi sin
2730 maskinvare. Nå som Debian var installert på datamaskinen gjenstod det
2731 å installere de nødvendige Skolelinux pakkene for å få til et
2732 fullverdig system. Disse pakkene ble installert manuelt i første
2733 omgang, men ble senere installert automatisk via et script som Petter
2734 Reinholdtsen laget. Dette scriptet er så enkel å bruke at man er i
2735 gang med installasjonen i løpet av bare
5 minutter. Ikke nok med det,
2736 alt skjer helt automatisk. Alt i alt er jeg veldig fornøyd med
2737 resultatet av installasjonsprosessen. Raspberry Pi er en veldig svak
2738 maskin og det merkes godt når man har installert Skolelinux på
2739 den. Video og
3D-rendering fungerer utrolig dårlig, men nettsurfing og
2740 kontorprogrammer fungerer godt. Det kan derfor konkluderes med at
2741 datamaskinen er egnet for enkle oppgaver.
2743 <p
>Jeg syns det er viktig påpeke at dette kun er startfasen av en slik
2744 løsning. På markedet finnes det nå maskiner som har bedre hardware enn
2745 Raspberry Pi. Det er store muligheter for at man kan klare å
2746 installere Skolelinux på disse også, og da forsvinner nok mest
2747 sannsynlig ytelsesproblemene med Video og
3D rendering også.
</p
>
2749 <p
>Det ble også prøvd med en løsning som gjorde at Raspberry Pi
2750 fungerte som en tynnklient. Denne løsningen hadde langt bedre ytelse
2751 med tanke på hastighet og brukeropplevelse. Men også her var video og
2752 3D rendering dårlig. Det ble brukt en liten Linux distribusjon kalt
2753 <a href=

2756 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
2758 <p
>Fordelen med Skolelinux er mange. At det er gratis er en stor
2759 fordel, men at det er så mange som er med på å utvikle det og
2760 vedlikeholde det er en enda større fordel. Allerede før jeg startet
2761 med prosjektet så jeg mange fordeler, og når jeg nærmet meg sluttfasen
2762 så jeg langt flere. At prosjektet skulle inneha en så høy kvalitet
2763 hadde jeg aldri trodd. En vanlig Skolelinux installasjon har de
2764 nødvendige programmene og funksjonen som både små og store skoler i
2765 tillegg til organisasjoner kan klare seg med. At prosjektet tilbyr en
2766 så komplett løsning er en kjempefordel. Installasjonen er knirkefri
2767 og det er svært enkelt å installere og komme i gang.
</p
>
2769 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
2771 <p
>Ulempene jeg ser med prosjektet er ryddigheten av websidene. Selv
2772 om websidene er enkle og konsise er det allikevel ikke appellerende i
2773 like stor grad som for eksempel
2774 <a href=
"http://www.ubuntu.com
">Ubuntu
</a
> sine sider. Deres side
2775 tilbyr, i tillegg til godt design og presentasjon, en nettbasert
2776 emulator av deres operativsystem. Dette er en stor fordel slik jeg ser
2777 det. Bortsett fra dette ser jeg absolutt ingen ulemper med
2778 Skolelinux-prosjektet.
</p
>
2780 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
2782 <p
>Til daglig er jeg en flittig bruker av det åpne media
2783 sentersystemet
<a href=
"http://xbmc.org/
">XBMC
</a
>. Det enorme
2784 samfunnet rundt dette prosjektet har gjort dette til et program som
2785 dekker alles behov. Man kan tilpasse det akkurat slik man vil både med
2786 tanke på utseende og funksjoner ved installere plug-ins eller
2789 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
2790 skoler til å ta i bruk fri programvare?
</strong
></p
>
2792 <p
>Strategien som burde brukes sett fra mine øyne er
2793 markedsføring. Jeg er sikker på at om flere skoler fikk et lite innsyn
2794 i hvor bra Skolelinux er så ville de ikke nølt med å gå over fra noe
2795 annet som koster de store summer. At skolelinux til de grader tilbyr
2796 en så komplett løsning bure komme frem. Enten via reklamekampanjer
2797 eller ved å sende ut folk til skoler for så å la skolenettverk
2798 ansvarlige få teste ut hvordan Skolelinux fungerer i praksis. Om det
2799 i tillegg ble utviklet gode websider og en emulator for å la brukere
2800 prøve operativsystemet ville nok dette ha styrket inntrykket
2801 betraktelig.

2822 lists and elsewhere, is the question on how to transform a Debian or
2823 Ubuntu installation into a Debian Edu installation. It isn
't very
2824 hard, and last week I wrote a script to replicate the steps done by
2825 the Debian Edu installer.

2830 transform an existing Debian Wheezy or Ubuntu (untested) installation
2831 into a Debian Edu Workstation:
</p
>
2835 <li
>Add skolelinux related APT sources.
</li

2836 <li
>Create /etc/debian-edu/config with the wanted configuration.

>Install debian-edu-install to load preseeding values and pull in
2838 our configuration.
</li

2839 <li
>Preseed debconf database with profile setup in
2840 /etc/debian-edu/config, and run tasksel to install packages
2841 according to the profile specified in the config above,
2842 overriding some of the Debian automation machinery.
</li

2843 <li
>Run debian-edu-cfengine-D installation to configure everything
2844 that could not be done using preseeding.
</li

2845 <li
>Ask for a reboot to enable all the configuration changes.
</li

2849 <p

2850 replicated like this. Disk partitioning and LVM setup, for example.
2851 So this script just assume there is enough disk space to install all

2858 transform it into a fully functioning Debian Edu Workstation (or
2859 Roaming Workstation, or whatever :).

2895 <p
>Debian Edu, also known as Skolelinux, is a Linux distribution based
2896 on Debian providing an out-of-the box environment of a completely
2897 configured school network. Immediatly after installation a school
2898 server running all services needed for a school network is set up just
2899 waiting for users and machines being added via GOsa², a comfortable
2900 Web-UI. A netbooting environment is prepared using PXE, so after
2901 initial installation of the main server from CD, DVD or USB stick all
2902 other machines can be installed via the network.
</p

3056 out-of-the box environment of a completely configured school
3057 network. Immediatly after installation a school server running all
3058 services needed for a school network is set up just waiting for users
3059 and machines being added via GOsa², a comfortable Web-UI. A netbooting
3060 environment is prepared using PXE, so after initial installation of
3061 the main server from CD, DVD or USB stick all other machines can be
3062 installed via the network.

3188 the video show a walk-through of of the menu content, demonstration of
3189 a few programs and his view of our distribution.
</p

3191 <p
>There is also some really nice quotes (transcribed by me, might
3192 have heard wrong). While looking thought the Graphics menu:
</p
>
3195 "Basically everything you ever need in a school environment.
"
3198 <p
>And as a general evaluation of the entire distribution:
</p
>
3201 "So, yeah, a bit bloated. It kept all the Debian stuff in there, just
3202 to keep it nice and GNU. So, I do not want to go on about it, but
3203 lets give it
7 out of
10. I am not going to use it. That is because
3204 I am not deploying a school network. There may be some mythical
3205 feature to help you deploy Skolelinux on a school network.
"
3208 <p
>To bad he did not test the server profile, and discovered the PXE
3209 installation option. It make it possible to install only the main
3210 server from CD, and the rest of the machines via the net, and might be
3211 considered the mythical feature he talk about. :)
</p
>
3213 <p
>While looking through the menus, there is also this funny comment
3214 about the part of the K menu generated from the Debian menu subsystem:
3217 "[The K menu] have a special Debian section for software that no-one
3218 is going to look at, because it contain lots of junky stuff that you
3219 actually don
't need in the education distribution, but have just been
3220 included because it isn
't stripped out for some reason.
"
3223 <p
>I guess it is yet another argument for merging the Debian menu and
3224 Gnome/KDE desktop menu entries into
3225 <a href=
"http://wiki.debian.org/Proposals/DebianMenuUsingDesktopEntries
">one
3226 consistent menu system
</a

3227 inconsistent menu systems.

>Etter en lang pause og travle uker har jeg endelig klart å få
3339 samlet et nytt intervju med en av folkene i
3340 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet.
3341 Denne gang er det Helge Tore Høyland, en mangeårig bidragsyter på
3342 epostlistene og ellers i prosjektet.
</p
>
3344 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
3346 <p
>Eg er IT-konsulent/teknikker hjå eit firma i Steinkjer med navn
3347 <a href=
"http://unoit.no/
">Uno IT
</a
>. Uno IT er eit lite firma som
3348 drifter nettverk og maskiner for små og mellomstore firma
3349 Steinkjer-området. Per dags dato er me
2 ansatte. Min faglege bakgrunn
3350 er Fagbrev som it-teknikker, samt nokre fag innen nettverk- og
3351 server-drift frå HiST og NTNU. Dagleg arbeid består i oppsett av nye
3352 maskiner og hjelp til sluttbrukere, samt oppsett og vedlikehold av eit
3353 vidt spekter av fagsystemer ute hjå kunder. Erfaring med Skolelinux
3354 har eg hatt i forbindelse med drifting av
3355 <a href=
"http://www.bjorkly.no/
">Bjørkly skule
</a
>, ein privat
3356 grunnskule i Namsos-området. I dag har skulen
65 elever,
15 lærere,
1
3357 hovedserver og ca
60 klienter som kjører halvtjukt. Eg har bygd og
3358 driftet systemet sidan summaren
2006.
</p
>
3360 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
3362 <p
>Eg kom i kontakt med Skolelinux-prosjektet via ein artikkel i eit
3363 fagblad, som eg ikkje lenger hugsar namnet på. I og med at eg allereie
3364 hadde pusla med nettverk for ein annan skule, fatta eg straks
3365 interesse for prosjektet.
</p
>
3367 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
3369 <p
>Fordelane med Skolelinux er sentralisert administrasjon og svært
3370 mange gode verktøy «ut av boksen». Veldig kjekt å kunne drifte
60
3371 klientar med berre å «bry» seg med ein server. Levetid for systemets
3372 hardware er og ein veldig fin effekt. I tillegg kjem fordelar som økt
3373 sikkerhet og mindre lisenskostnader. Etter min erfaring er det og
3374 mykje mindre driftskostnader med eit slikt system enn konkurrerande
3375 system, pga enkelhet med sentralisert administrasjon. På grunn av at
3376 Skolelinux er basert på Debian er det òg svært stabilt.
</p
>
3378 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
3380 <p
>Ulemper er mangel på vilje til å følge standarer ute i markedet,
3381 som fører til mangel på støtte til nokre mykje brukte ting. Flash og
3382 Java er typiske eksempel. Sidan Debian satsar på stabilitet framfor å
3383 ha nyeste pakke av eit program, kan ein i nokre tilfeller kome borti
3384 at program vert «for gamle». Det er spesielt nettlesaren som er
3385 utsett. Mangel på vilje til å utvikle pedagogisk programvare, i Noreg,
3386 for «alle» platformer fører òg til noko hovudbry.
</p
>
3388 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
3390 <p
>Til dagleg bruker eg svært mange forskjellige «fri programvare»
3391 program. Firefox, Thunderbird, Freecommander, ImgBurn, Clonezilla,
3392 OCS inventory, Icinga, Skolelinux, SystemRescueCD og mykje meir.
</p
>
3394 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
3395 skoler til å ta i bruk fri programvare?
</strong
></p
>
3397 <p
>Strategisk må ein fokusere på at sluttbruker eigentleg ikkje er så
3398 fokusert på at det er fri programvare men at det skal «berre fungere».
3399 Gjer det enkelt å bruker og ikkje minst å administrere. For Skolelinux
3400 sin del må ein få eit betre fokus på overganger. Utbytting av servere
3401 må gå meir automatisk, import og eksport av brukerbase og maskinbase
3402 med meir må kunne gå enkelt og oppgradering til neste versjon må bli
3403 mykje meir automatisk og gjennomtesta. Ein må unngå at ein må sette
3404 opp frå start når ein byter ut ein server eller oppgraderer til neste
3405 versjon. For å få Skolelinux til å bli eit betre alternativ for skular
3406 må ein ha fokus på nettlesaren. Denne må bli «up to date» og støtte
3407 dei protokollar og tillegg som vert brukt av forlag med meir. Etter
3408 kvart som meir og meir blir flytta ut i «skya» vert dette viktigare og
3409 viktigare. Ein kunne ynskje og jobbe for at forlag med fleire tar i
3410 bruk opne standarer, men inntil det skjer, må systemet kunne brukast
3411 mot desse fagsystema.
</p
>
3413 <p
>For meg har prosjektet med Skolelinux vore ein svært artig og
3414 lærerik prosess. Miljøet rundt er ikkje enormt stort, dog stort nok,
3415 men det er svært hjelpevillig og engasjert.

3429 present. As the Debian Edu / Skolelinux project is very short on
3430 funding these days, and thus lack the money to do regular developer
3431 gatherings, this donation was most welcome. One developer gathering
3432 cost around NOK
15&nbsp;

3452 interesting, as I am involved with several organizations where
3453 accounting is an issue, and I have not really become too friendly with
3454 the different web based systems we use. I find it hard to find what I
3455 look for in the menus and even harder try to get sensible data out of
3456 the systems. Ledger seem different. The accounting data is kept in
3457 text files that can be stored in a version control system, and there
3459 are at least
<a href=

3460 different implementations

">IT-Zukunft Schule

3514 project out from maternity leave to conduct an interview. Give a warm
3515 welcome to Angela Fuß. :)
</p
>
3517 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
3519 <p
>I am a
39-year-old woman living in the very north of Germany near
3520 Denmark. I live in a patchwork family with
"my man
" Mike Gabriel, my
3521 two daughters, Mikes daughter and Mikes and my rather newborn son.
3523 <p
>At the moment - because of our little baby - I am spending most of
3524 the day by being a caring and organising mom for all the kids.
3525 Besides that I am really involved into and occupied with several inner
3526 growth processes: New born souls always bring the whole familiar
3527 system into movement and that needs time and focus ;-). We are also
3528 in the middle of buying a house and moving to it.
</p
>
3530 <p
>In
2013 I will work again in my job in a German foundation for
3531 nature conservation. I am doing public relation work there. Besides
3532 that - and that is the connection to Skolelinux / Debian Edu - I am
3533 working in our own school project
"IT-Zukunft Schule
" in North
3534 Germany. I am responsible for the quality assurance, the customer
3535 relationship management and the communication processes in the
3538 <p
>Since
2001 I constantly have been training myself in communication
3539 and leadership. Besides that I am a forester, a landscaping gardener
3540 and a yoga teacher.
</p
>
3542 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
3543 project?
</strong
></p
>
3545 <p
>I fell in love with Mike ;-).
</p
>
3547 <p
>Very soon after getting to know him I was completely enrolled into
3548 Free Software. At this time Mike did IT-services for one newly
3549 founded school in Kiel. Other schools in Kiel needed concepts for
3550 their IT environment. Often when Mike came home from working at the
3551 newly founded school I found myself listening to his complaints about
3552 several points where the communication with the schools head or the
3553 teachers did not work. So we were clear that he would not work for
3554 one more school if we did not set up a structure for communication
3555 between him, the schools head, the teachers, the students and the
3558 <p
>Together with our friend and hardware supplier Andreas Buchholz we
3559 started to get an overview of free software solutions suitable for
3560 schools. One day before Christmas
2010 Mike and I had a date with Kurt
3561 Gramlich in Gütersloh. As Kurt and I are really interested in building
3562 networks of people and in being in communication we dived into
3563 Skolelinux and brought it to the first grammar schools in Northern
3566 <p
>For information about our school project you can read

</p
>
3570 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
3571 Edu?
</strong
></p
>
3573 <p
>First I have to say: I cannot answer this question technically. My
3574 answer comes rather from a social point of view.
</p
>
3576 <p
>The biggest advantage of Skolelinux / Debian Edu I see is the large
3577 and strong international community of Debian Developers in the
3578 background which is very alive and connected over mailinglists, blogs
3579 and meetings. My constant feeling for the Debian Community is: If
3580 something does not work they will somehow fix it. All is well
3581 ;-). This is of course a user experience. What I also get as a big
3582 advantage of Skolelinux / Debian Edu is that everybody who uses it and
3583 works with it can also contribute to it - that includes students,
3584 teachers, parents...
</p
>
3586 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
3587 Edu?
</strong
></p
>
3589 <p
>I will answer this question relating to the internal structure of
3590 Skolelinux / Debian Edu.
</p
>
3592 <p
>What I see as a major disadvantage is that there is a gap between
3593 the group of developers for Debian Edu and the people who make the
3594 marketing, that means the people that bring Skolelinux to the
3595 schools. There is a lack of communication between these two groups and
3596 I think that does not really work for Skolelinux / Debian Edu.
</p
>
3598 <p
>Further I appreciate that Skolelinux / Debian Edu is known as a
3599 do-ocracy. Nevertheless I keep asking myself if at some points a
3600 democracy or some kind of hierarchical project structure would be good
3601 and helpful. I am also missing some kind of contact between the
3602 Skolelinux / Debian Edu communities in Europe or on an international
3603 level. I think it would be good if there was more sharing between the
3604 different countries using Skolelinux / Debian Edu.
</p
>
3606 <p
><strong
>Which free software do you use daily?
</strong
></p
>
3608 <p
>On my laptop I am still using an Ubuntu
10.04 with a Gnome Desktop
3609 on. As applications I use Openoffice.org, Gedit, Firefox, Pidgin,
3610 LaTeX and GnuCash. For mails I am using Horde. And I am really fond of
3611 my N900 running with Maemo.
</p
>
3613 <p
><strong
>Which strategy do you believe is the right one to use to
3614 get schools to use free software?
</strong
></p
>
3616 <p
>I am really convinced that in our school project
"IT-Zukunft
3617 Schule
" we have developed (and keep developing) a great way to get
3618 schools to use Free Software. We have written a detailed concept for
3619 that so I cannot explain the whole thing here. But in a nutshell the
3620 strategy has three crucial pillars:
</p
>
3624 <li
>We really take time to get what sort of stories, questions and
3625 concerns the schools head and the teachers have about using different
3626 kinds of IT and we take time to enrol them into Free Software.
</li
>
3628 <li
>Our solution for schools is never just technical. In the centre
3629 are always the people who are going to use the software. From the very
3630 beginning of the planning for a school, we tell the schools head that
3631 they are paying us not only for a technical solution for their school,
3632 they also pay us for leading all the communication processes
3633 needed. If they do not want that, we are not working with them because
3634 we cannot give a guarantee for the quality of our work then.
</li
>
3636 <li
>Another focus lies in the training of teachers and students in
3637 co-administrating the IT-System at their school. They start getting in
3638 contact with the Skolelinux / Debian Edu community and they get the
3639 offer to become more and more independent from us.

3662 <p
>I sommer (
2012-
07-
23) hadde Fremover et oppslag om at Narvik
3663 kommune hadde spart mellom
10 og
20 millioner kroner de siste årene på
3664 å bruke Skolelinux på sine skoler. Harstad har også tatt i bruk
3665 Skolelinux på alle sine skoler. Som tidligere Ballangsværing gledet
3666 det meg stort å se at skoleløsningen vi har utviklet siden
2001 tas i
3667 bruk i området der jeg vokste opp, og dermed bidrar til en bedre og
3668 billigere skolehverdag.
</p
>
3670 <p
>Skolelinux er en komplett IT-løsning for elevnettverket på en
3671 skole, med både nettverkstjenester og løsning for elevmaskiner med
3672 pedagogisk programvare, som tillater en å øke levetiden på en
3673 datamaskin i skolen med mange år. En undersøkelse publisert i mars
3674 2012 viste at de
56 norske skolene som har offentliggjort at de bruker
3675 Skolelinux eller annen Linuxutgave hadde
36% større PC-tetthet enn
3676 landsgjennomsnittet, når en ser på tall rapportert til Grunnskolens
3677 Informasjonssystem. I følge Paul Reidar Løsnesløkken, IKT-konsulent i
3678 Nord-Odal, fungerer datamaskiner godt til de er
8 til
10 år gamle.
</p
>
3680 <p
>I høst (
2012-
09-
29) fortalte Fremover hvordan Ballangen kommune har
3681 opparbeidet seg
20 millioner i underskudd og nok havner på Robek-lista
3682 fra nyttår. Kanskje Ballangen også burde ta i bruk Skolelinux for å
3683 spare penger? Hvis kommunen mangler kompetanse lokalt på Linux finnes
3684 det kommersielle selskaper som tilbyr driftstjenester rundt
3685 Skolelinux, og jeg bør vel avsløre at jeg selv er involvert i et av
3686 dem, Skolelinux Drift AS. Kommunen kan dermed få hjelp hvis de ikke
3687 ønsker å bygge opp egen kompetanse.

3758 noe utviklerne er veldig glade for.

3760 <p

3761 skrevet om til å akseptere ord med bindestrek (f.eks. «e-post»). Litt
3762 over
10.000 slike ordformer er lagt til i orddatabasen. I tillegg er
3763 det kommet en del nye ord og rettelser rapportert inn av de frivillige

>After a long break in my row of interviews with people in the
3855 <a href=
"http://www.skolelinux.org/
">Debian Edu and Skolelinux
</a
>
3856 community, I finally found time to wrap up another. This time it is
3857 Giorgio Pioda, which showed up on the mailing list at the start of
3858 this year, asking questions and inspiring us to improve the first time
3859 administrators experience with Skolelinux. :) The interview was
3860 conduced in May, but I only found time to publish it now.
</p
>
3862 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
3864 <p
>I have a PhD in chemistry but since several years I work as teacher
3865 in secondary (
15-
18 year old students) and tertiary (a kind of
"light
"
3866 university) schools. Five years ago I started to manage a Learning
3867 Management Service server and slowly I got more and more involved with
3868 IT.
3 years ago the graduating schools moved completely to Linux and I
3869 got the head of the IT for this. The experience collected in chemistry
3870 labs computers (for example NMR analysis of protein folding) and in
3871 the IT-courses during university where sufficient to start. Self
3872 training is anyway very important
</p
>
3874 <p
>I live in the Italian speaking part of Switzerland, and the
3875 <a href=
"http://www.spse.ch/
">SPSE school
</a
> (secondary) is a very
3876 special sport school for young people who try to became sport pro (for
3877 all sports, we have dozens of disciplines represented) and we are
3878 recognised by the Olympic Swiss Organisation.
3880 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
3881 project?
</strong
></p
>
3883 <p
>Looking for Linux / Primary Domain Controller (PDC) I found it
3884 already several years ago. But since the system was still not
3885 Kerberized and since our schools relies strongly on laptops I didn
't
3886 use it. I plan to introduce it in the next future, probably for the
3887 next school year, since the squeeze release solved this security
3890 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
3891 Edu?
</strong
></p
>
3893 <p
>Many. First of all there is a strong and living community that is
3894 very generous for help and hints. Chat help is crucial, together with
3895 the mailing list. Second. With Skolelinux you get an already well
3896 engineered platform and you don
't have to start to build up your PDC
3897 and your clients from GNU/scratch; I
've already done this once and I
3898 can tell it, it is hard. Third, since Skolelinux is a standard
3899 platform, it is way easier to educate other IT people and even if the
3900 head IT is sick another one could pick up the task without too much
3903 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
3904 Edu?
</strong
></p
>
3906 <p
>The only real problem I see is that it is a little too less
3907 flexible at client level. Debian stable is rocky and desirable, but
3908 there are many reasons that force for another choice. For example the
3909 need of new drivers for new PC, or the need for a specific OS for some
3910 devices that have specific software packages for another specific
3911 distribution (I have such a case for whiteboards that have only
3912 Ubuntu packages). Thus, I prepared compatibility packages educlient
3913 and eduroaming, hoping not to use them ;-)
</p
>
3915 <p
><strong
>Which free software do you use daily?
</strong
></p
>
3917 <p
>I have a Debian Stable PDC at school (Kerberos, NIS, NFS) with
3918 mixed Debian and Ubuntu clients. If you think that this triad
3919 combination is exotic... well I discovered right yesterday that
3920 <a href=
"http://moo.nac.uci.edu/~hjm/Perceus-Report.html
">Perceus
</a
>
3921 has the same...
</p
>
3923 <p
>For myself I run Debian wheezy/sid, but this combination is good
3924 only I you have enough competence to fix stuff for yourself, if
3925 something breaks. Daily I use texmacs, gnumeric, a little bit of R
3926 statistics, kmplot, and less frequently OpenOffice.org.
</p
>
3928 <p
><strong
>Which strategy do you believe is the right one to use to
3929 get schools to use free software?
</strong
></p
>
3931 <P
>I think that the only real argument that school managers
"hear
" is
3932 cost reduction. They don
't give too much weight on quality, stability,
3933 just because they are normally not open to change.
</p
>
3935 <p
>Students adapts very quickly to GNU/Linux (and for them being able
3936 to switch between different OS is a plus value); teachers and managers
3937 don
't.
</p
>
3939 <p
>We decided to move to Linux because students at our school have own
3940 laptop and we have the responsibility to keep the laptop ready to use;
3941 we were really unsatisfied with Microsoft since every Monday we had
20
3942 machine to fix for viral infections... With Linux this has been
3943 reduced to zero, since people installs almost only from official
3944 repositories. I think that our special needs brought us to Linux.
3945 Those who don
't have such needs will hardly move to Linux.

3960 vært vellykket.
</p

3962 <p
>Artikkelen med tittelen
"Narvik kommune bruker gratisprogram i
3963 skolen - Har spart millioner
", forteller om hvordan bruken av
3964 Skolelinux er en stor suksess i Narvik siden det ble tatt i bruk i
3965 2004. Her er noen fine sitater:
</p
>
3968 "- Skolelinux har spart kommunen for store pengesummer, millionbeløp,
3969 som de heller kan bruke på andre ting, sier IKT-konsulent Viggo
3973 <p
>Avisen forteller at de har fått tilgang til beregninger som viser
3974 at Narvik kommune har spart noe mellom
10 og
20 millioner kroner de
3975 siste
8 årene på å bruke Skolelinux, og fortsetter:
</p
>
3979 "Regnestykket tar høyde for sparte kostnader til lisenser som medfølger
3980 de alternative operativsystemene, lavere driftskostnader og lengre
3981 levetid på datautstyret. Totalt har Narvikskolen en maskinpark på
3982 1600 maskiner fordelt på de
11 skolene fra Skjomen i sør til Bjerkvik
3987 <p
>Viggo Fedreheim sier dette om hvor noe av gevinsten kommer fra:
</p
>
3990 "- Vi kan gjenbruke gamle maskiner i skolen som er for dårlig andre
3991 steder i kommunen der de ikke bruker Skolelinux. Levetiden på en
3992 datamaskin blir
3-
5 år lenger med Skolelinux. Vi kaller det for
3993 grønn IT, miljøvennlig IT.
"
3996 <p
>Her er det mulighet for flere kommuner å få et godt IT-system på
3997 skolene, hvis de er villige til å forsøke. De som ikke har kompetanse
3998 innomhus kan kjøpe det fra en av de kommersielle leverandørene av

>I
'm a
44 year old country guy that have been working
12 years at
4074 the same school as
50% IT-manager and
50% Teacher. My educational
4075 background is fil.kand in history and religious beliefs, an exam as a
4076 "folkhighschool
" teacher, that is, for teaching grownups. In
4077 Norwegian I believe it
's called
"Vuxenupplaring
". I also have a master
4078 in
"Technology and social change
". So I
'm not really a tech guy, I
4079 just like to study how humans and technology interact and that is my
4080 perspective when working with IT.
</p
>
4082 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4083 project?
</strong
></p
>
4085 I have followed the Skolelinux project for quite some time by
4086 now. Earlier I tested out the K12-LTSP project, which we used for some
4087 time, but I really like the idea of having a distribution aimed to be
4088 a complete solution for schools with necessary tools integrated. When
4089 K12-LTSP abandoned that idea some years ago, I started to look more
4090 seriously into Skolelinux instead.
4092 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4093 Edu?
</strong
></p
>
4095 The big point of Skolelinux to me is that it is a complete
4096 distribution, ready to install. It has LDAP-support, MS Windows
4097 integration tools and so forth already configured, saving an
4098 administrator a lot of time and headache. We were using another Linux
4099 based thin-client system called Thinlinc, that has served us very
4100 well. But that Skolelinux is based on VNC and LTSP, to me, is better
4101 when it comes to the kind of multimedia used in schools. That is
4102 showing videos from Youtube or educational TV. It is also easier to
4103 mix thin clients with workstations, since the user settings will be the
4104 same. In our VNC-based solution you had to
"beat around the bush
" by
4105 setting up a second, hidden, home-directory for user settings for the
4106 workstations, because they will be different from the ones used on the
4107 thin clients. Skolelinux support for diskless workstations are very
4108 convenient since a school today often need to use a class room
4109 projector showing videos in full screen. That is easily done with a
4110 small integrated media computer running as a diskless workstation. You
4111 have only two installs to update and configure. One for the thin
4112 clients and one for the workstations. Also saving a lot of time. Our
4113 old system was also based on Redhat and CentOS. They are both very
4114 nice distributions, but they are sometimes painfully slow when it
4115 comes to updating multimedia support and multimedia programs (even
4116 such as Gimp), leaving us with a bit
"oldish
" applications. Debian is
4119 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
4120 Edu?
</strong
></p
>
4122 <p
>Debian is a bit too quick when it comes to updating. As an example
4123 we use old HP terminals as thinclients, and two times already this
4124 year (
2012) the updates you get from the repositories has stopped
4125 sound from working with them. It
's a kernel/ALSA issue. So you have
4126 to be more careful properly testing the updates before you run them in
4127 a production environment. This has never happened with CentOS.
</p
>
4129 <p
>I also would like to be able to set my own domain-settings at
4130 install time. In Skolelinux they are kind of hard coded into the
4131 distribution, when it comes to LDAP and at least samba integration.
4132 That is more a cosmetic/translation issue, and not a real problem.
4133 Running MS Windows applications within the Skolelinux environment needs
4134 to be better supported. That is, running them seamlessly via RDP, and
4135 support for single-sign on. That will make the transition to free
4136 software easier, because you can keep the applications you really
4137 need. No support will make it impossible if you work in a school where
4138 some applications can
't be open source. As for us we really need to
4139 run Adobe InDesign in our journalist classes. We run a journalist
4140 education, and is one of the very few non university ones that is ok:d
4141 by Svenska journalistförbundet (Swedish journalist association). Our
4142 education gives the pupils the right of membership there, once they
4143 are done. This is important if you want to get a job.
</p
>
4145 <p
>Adobe InDesign is the program most commonly used in newspapers and
4146 magazines. We used Quark Express before, but they seem to loose there
4147 market to Adobe. The only
"equivalent
" to InDesign in the opensource
4148 world is Scribus, and its not advanced enough. At least not according
4149 to the teacher. I think it would be possible to use it, because they
4150 are not supposed to learn a program, they are supposed to learn how to
4151 edit and compile a newspaper. But politically at our school we are not
4152 there yet. And Scribus lacks a lot of things you find i InDesign.
</p
>
4154 <p
>We used even a windows program for sound editing when it comes to
4155 the radio-journalist part. The year to come we are going to try
4156 Audacity. That software has the same kind of limitations compared to
4157 Adobe Audition, but that teacher is a bit more open minded. We have
4158 tried Ardour also, but that instead is more like a music studio
4159 program, not intended for the kind of editing taking place in a radio
4160 studio. Its way to complex and the GUI is to scattered when you only
4161 want to cut, make pass-overs, add extra channels and normalise. Those
4162 things you can do in Audacity, but its not as easy as in Audition. You
4163 have to do more things manually with envelopes, and that is a bit old
4164 fashion and timewasting. Its also harder to cut and move sound from
4165 one channel to another, which is a thing that you do frequently
4166 because you often find yourself needing to rearrange parts of the
4167 sound file.
</p
>
4169 <p
>So, I am not sure we will succeed in replacing even Audition, but we
4170 will try. The problem is the students have certain expectations when
4171 they start an education towards a profession. So the programs has to
4172 look and feel professional. Good thing with radio, there are many
4173 programs out there, that radio studios use, so its not as standardised
4174 as Newspaper editing. That means, it does not really matter what
4175 program they learn, because once they start working they still have to
4176 learn the program the studio uses, so instead focus has to be to learn
4177 the editing part without to much focus on a specific software.
</p

4179 <p
><strong
>Which free software do you use daily?
</strong
></p
>
4181 <p
>Myself I
'm running Linux Mint, or Ubuntu these days. I use almost
4182 only open source software, and preferably Linux based. When it comes
4183 to most used applications its OpenOffice, and Firefox (of course ;)
4186 <p
><strong
>Which strategy do you believe is the right one to use to
4187 get schools to use free software?
</strong
></p
>
4189 <p
>To get schools to use free software there has to be good open
4190 source software that are windows based, to ease the transition. But
4191 it
's also very important that the multimedia support is working
4192 flawlessly. The problems with Youtube, Twitter, Facebook and whatever
4193 will create problems when it comes to both teachers and
4194 students. Economy are also important for schools, so using thin
4195 clients, as long as they have good multimedia support, is a very good
4196 idea. It
's also important that the open source software works even for
4197 the administration. It
's hard to convince the teachers to stick with
4198 open source, if the principal has to run Windows. It also creates a
4199 problem if some classes has to use Windows for there tasks, since that
4200 will create a difference in
"status
" between classes, so a good
4201 support for running windows applications via the thin client (Linux)
4202 desktop is essential. At least at our school, where we have mixed
4203 level of educations, from high-school to journalist-school.

>In the Debian Edu / Skolelinux project, we have realised that one
4223 of the major blockers for the project success is the purchasing skills
4224 in schools and municipalities. We provide what the happy users of
4225 Debian Edu / Skolelinux say they need and to a lower cost than the
4226 alternatives, and yet so few schools decide to use our solution. I
4227 was pleased to discover the same observation done by mySociety and Tom
4228 Steinberg in his blog post
4229 "<a href=

4231 spending of your tax money.
</p

4233 <p
>Of course there are other factors involved as well, like our
4234 projects bad marketing skills and the Linux community fragmentation
4235 causing worry with the people on the outside, so we as a project need
4236 to keep working hard to gain users, but it is a up-hill battle when
4237 public decision makers are unable to understand computer system
4238 purchases.

40 år. Utdannet biolog med ymse
4440 fag på siden. Har jobbet som lærer der jeg var driftsansvarlig på
4441 Ulsrud VGS i Oslo. Senere eide og jobbet jeg flere år i Linuxlabs AS,
4442 som jeg solgte til Redpill Linpro AS (den gangen Linpro AS). I dag
4443 jobber jeg med ulike investeringer, hovedsaklig i eiendom, men også i
4444 en del ulike IT-relaterte bedrifter.

>Fruen og jeg dro på en lengre seiltur i
2000, der jeg måtte ha
"noe
4449 å gjøre
" under hjemturen over Atlanteren. Jeg kjøpte et par bøker om
4450 Linux i en bokhandel i New York og ble veldig fascinert. Etter
4451 hjemkomsten begynte jeg å jobbe på Ulsrud VGS, som naturfagslærer, men
4452 som IT-interessert ble jeg fort en del av den nye IT-satsningen som
4453 skulle løfte Ulsrud og gi skolen en bedre rykte. Vi hadde ganske
4454 mange maskiner, som gikk på Win98 og to servere som ble oppgradert til
4455 Win2000. Systemene var ustabil og dårlige. På leting etter noe
4456 bedre, uten å knekke ryggen økonomisk, kom jeg over
"Linux i Skolen
"
4457 og Skolelinux. Jeg tok kontakt med miljøet og en gjeng møtte opp på
4458 skolen, der vi gjorde en liten testinstallasjon. Etter et par år var
4459 ryggraden på skolen Linux (Skolelinux) og vi hadde flere hundre
4460 maskiner, både tynne klienter (gamle og nye), bærbare (Debian) og noen
4461 stasjonære (Win2000). På et tidspunkt var Ulsrud den råeste IT-skolen
4462 og det irriterte skolesjefen i Oslo, da de satset hardt på

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

4467 <p
>Det som gjorde at vi fikk inn Skolelinux var ene og alene
4468 økonomiske. Det faktum at vi slapp å kjøpe masse nye lisenser og at
4469 vi kunne bruke gammel hardware. Alt i alt gjorde dette at vi sparte
4470 mye, men i stede for å bruke mindre på IT brukte vi det vi sparte på å
4471 skaffe mer hardware og på den måten gi det beste tilbudet i landet til
4472 våre elever. For oss som driftet var det himmel å ha et system som
4473 gikk å administrere sentralt og effektivt. Det var heller ikke så
4474 dumt at vi kunne
"låse
" maskinene mer effektivt enn vi kunne med
4475 Microsoft Windows, slik at vi slapp mye feil og problemer som ble
4476 forårsaket av
"kreative
" elever.

4480 <p
>Det vi slet med var mangelen av en del programmer lærerne ville ha.
4481 Husker ikke alle, men det var et knippe med pedagogiske programmer de
4482 ikke fikk. I dag tror jeg det problemet er langt mindre da det meste
4483 av disse kjøres gjennom nettleseren.

4487 <p
>Jeg bruker mye Apple i dag og er ikke så stolt av det, men jeg har
4488 både OpenOffice, Firefox og en del andre programmer på den bærbare.
4489 Firefox brukes mest av disse. På Apple-serveren hjemme bruker jeg
4490 HandBrake mye, og jeg har installert OpenWRT på flere av
4491 basestasjonene både hjemme og på jobben. I tillegg til det har jeg i
4492 flere år finansiert et prosjekt som heter
4493 <a href=

">Found IT
</a

4494 vi lager et rammeverk for søk, der alt vi bruker fri programvare. Det

4498 skoler til å ta i bruk fri programvare?

4500 <p
>Når det gjelder IT og skole er fortsatt økonomi veldig viktig. Så
4501 man må oppfylle minimumskravene (ikke være best, men bra nok) og selge
4502 seg inn på hvor mye man sparer. Det betyr selvsagt at man sparer på
4503 lisenser, men også på driftsinnsats. Men nå når jeg ikke er en aktiv
4504 del av miljøet lenger hører jeg nesten ingen ting om fri programvare.
4505 Jeg stiller meg da spørsmålet om det har blitt stille rundt miljøet,
4506 eller om jeg kun så det tydeligere før når jeg var aktiv? Uansett er
4507 det for stille rundt Skolelinux-prosjektet nå.

4517 another interview with the people behind
4518 <a href=

">Debian Edu and Skolelinux
</a
>.
4519 This time we get to know José Luis Redrejo Rodríguez, one of our great
4520 helpers from Spain. His effort was the reason we added support for
4521 several desktop types (KDE, Gnome and most recently LXDE) in Debian
4522 Edu, and have all of these available in the recently published

>I
'm a father, teacher and engineer who is working for the Education

><strong
>How did you get in contact with the Skolelinux/Debian Edu
4533 project?
</strong
></p
>
4535 <p
>At
2006, I verified that both, we in Extremadura and Skolelinux
4536 project, had been working in parallel for some years, doing very
4537 similar things, using very similar tools and with similar targets, so
4538 I decided it was time to join forces as much as possible.
</p

4540 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4541 Edu?
</strong
></p
>
4543 <p
>A community of highly skilled experts working together, with a
4544 really open schema of collaboration and work. I really love the
4545 concepts of Do-ocracy and Merit-ocracy and the way these concepts are
4546 been used everyday inside Debian Edu.
</p
>
4548 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
4549 Edu?
</strong
></p
>
4551 <p
>Sometimes the differences in the implementations, laws or
4552 economical and technical resources in the different countries don
't
4553 allow us to agree in the same solution for all of us, and several
4554 approaches are needed, what is a waste of effort. Also, there is a
4555 lack of more man power to be able to follow the fast evolution of the
4556 technologies in school.
</p
>
4558 <p
><strong
>Which free software do you use daily?
</strong
></p

4560 <p

</p
>
4564 <p
><strong
>Which strategy do you believe is the right one to use to
4565 get schools to use free software?
</strong
></p
>
4567 <p
>I think there is not a single strategy because there are very
4568 different scenarios: schools with mixed proprietary and free
4569 environments, schools using only workstations, other schools using
4570 laptops, netbooks, tablets, interactive white-boards, etc.
</p
>
4572 <p
>Also the range of ages of the students is very broad and you can
4573 not use the same solutions for primary schools and secondary or even
4574 universities. So different strategies are needed.
</p
>
4576 <p
>But, looking at these differences, and looking back to the things
4577 we
've done and implemented, and the places were we have spent most of
4578 our forces, I think we should focus as much as possible in free
4579 multi-platform environments, using only standards tools, and moving
4580 more and more to Internet or network solutions that could be deployed
4581 using wireless. I think we
'll see more and more personal devices in
4582 the schools, devices the students and teachers will take home with
4583 them, so the solutions must be able to be taken at home and continue
4584 working there.

"http://www.debian.org/News/

20120311.nb.html
">Debian Edu
4595 based on Squeeze
</a
>, I came across some issues that should be
4596 addressed in the Wheezy release. I finally found time to wrap up my
4597 notes and provide quick summary of what I found, with a bit
4598 explanation.
</p
>
4602 <li
>We need to rewrite our package installation framework, as tasksel
4603 changed from using tasksel tasks to using meta packages (aka packages
4604 with dependencies like our education-* packages), and our installation
4605 system depend on tasksel tasks in
4606 /usr/share/tasksel/debian-edu-tasks.desc for package
4607 installation.
</li
>
4609 <li
>Enable Kerberos login for more services. Now with the Kerberos
4610 foundation in place, we should use it to get single sign on with more
4611 services, and avoiding unneeded password / login questions. We should
4612 at least try to enable it for these services:
4615 <li
>CUPS for admins to add/configure printers and users when using
4617 <li
>Nagios for admins checking the system status.
</li
>
4618 <li
>GOsa for admins updating LDAP and users changing their passwords.
</li
>
4619 <li
>LDAP for admins updating LDAP.
</li
>
4620 <li
>Squid for users when exam mode / filtering is active.
</li
>
4621 <li
>ssh for admins and users to save a password prompt.
</li
>
4623 </ul
></li
>
4625 <li
>When we move GOsa to use Kerberos instead of LDAP bind to
4626 authenticate users, we should try to block or at least limit access to
4627 use LDAP bind for authentication, to ensure Kerberos is used when it
4628 is intended, and nothing fall back to using the less safe LDAP bind
</li
>
4630 <li
>Merge debian-edu-config and debian-edu-install. The split made
4631 sense when d-e-install did a lot more, but these days it is just an
4632 inconvenience when we update the debconf preseeding values.
</li
>
4634 <li
>Fix partman-auto to allow us to abort the installation before
4635 touching the disk if the disk is too small. This is
4636 <a href=
"http://bugs.debian.org/
653305">BTS report #
653305</a
> and the
4637 d-i developers are fine with the patch and someone just need to apply
4638 it and upload. After this is done we need to adjust
4639 debian-edu-install to use this new hook.
</li
>
4641 <li
>Adjust to new LTSP framework (boot time config instead of install
4642 time config). LTSP changed its design, and our hooks to install
4643 packages and update the configuration is most likely not going to work
4646 <li
>Consider switching to NBD instead of NFS for LTSP root, to allow
4647 the Kernel to cache files in its normal file cache, possibly speeding
4648 up KDE login on slow networks.
</li
>
4650 <li
>Make it possible to create expired user passwords that need to
4651 change on first login. This is useful when handing out password on
4652 paper, to make sure only the user know the password. This require
4653 fixes to the PAM handling of kdm and gdm.
</li
>
4655 <li
>Make GUI for adding new machines automatically from sitesummary.
4656 The current command line script is not very friendly to people most
4657 familiar with GUIs. This should probably be integrated into GOsa to
4658 have it available where the admin will be looking for it..
</li
>
4660 <li
>We should find way for Nagios to check that the DHCP service
4661 actually is working (as in handling out IP addresses). None of the
4662 Nagios checks I have found so far have been working for me.
</li
>
4664 <li
>We should switch from libpam-nss-ldapd to sssd for all profiles
4665 using LDAP, and not only on for roaming workstations, to have less
4666 packages to configure and consistent setup across all profiles.
</li
>
4668 <li
>We should configure Kerberos to update LDAP and Samba password
4669 when changing password using the Kerberos protocol. The hook was
4670 requested in
<a href=
"http://bugs.debian.org/
588968">BTS report
4671 #
588968</a
> and is now available in Wheezy. We might need to write a
4672 MIT Kerberos plugin in C to get this.
</li
>
4674 <li
>We should clean up the set of applications installed by default.
4677 <li
>reduce the number of chemistry visualisers
</li
>
4678 <li
>consider dropping xpaint
</li
>
4679 <li
>and probably more?
</li
>
4680 </ul
></li
>
4682 <li
>Some hardware need external firmware to work properly. This is
4683 mostly the case for WiFi network cards, but there are some other
4684 examples too. For popular laptops to work out of the box, such
4685 firmware need to be installed from non-free, and we should provide
4686 some GUI to do this. Ubuntu already have this implemented, and we
4687 could consider using their packages. At the moment we have some
4688 command line script to do this (one for the running system, another
4689 for the LTSP chroot).
</li
>
4692 <li
>In Squeeze, we provide KDE, Gnome and LXDE as desktop options. We
4693 should extend the list to Xfce and Sugar, and preferably find a way to
4694 install several and allow the admin or the user to select which one to
4697 <li
>The golearn tool from the goplay package make it easy to check out
4698 interesting educational packages. We should work on the package
4699 tagging in Debian to ensure it represent all the useful educational
4700 packages, and extend the tool to allow it to use packagekit to install
4701 new applications with a simple mouse click.
</li
>
4703 <li
>The Squeeze version got half a exam solution already in place,
4704 with the introduction of iptable based network blocking, but for it to
4705 be a complete exam solution the Squid proxy need to enable
4706 filtering/blocking as well when the exam mode is enabled. We should
4707 implement a way to easily enable this for the schools that want it,
4708 instead of the
"it is documented
" method of today.
</li
>
4710 <li
>A feature used in several schools is the ability for a teacher to
4711 "take over
" the desktop of individual or all computers in the room.
4712 There are at least three implementations,
4713 <a href=
"italc.sourceforge.net/
">italc
</a
>,
4714 <a href=
"http://www.itais.net/help/en/
">controlaula
</a
> og
4715 <a href=
"http://www.epoptes.org/
">epoptes
</a
> and we should pick one of
4716 them and make it trivial to set it up in a school. The challenges is
4717 how to distribute crypto keys and how to group computers in one room
4718 and how to set up which machine/user can control the machines in a
4719 given room.
</li
>
4721 <li
>Tablets and surf boards are getting more and more popular, and we
4722 should look into providing a good solution for integrating these into
4723 the Debian Edu network. Not quite sure how. Perhaps we should
4724 provide a installation profile with better touch screen support for
4725 them, or add some sync services to allow them to exchange
4726 configuration and data with the central server. This should be
4727 investigated.

><strong
>Who are you, and how do you spend your days?
</strong
></p
>
4750 <p
>My name is Mike Gabriel, I am
38 years old and live near Kiel,
4751 Schleswig-Holstein, Germany. I live together with a wonderful partner
4752 (Angela Fuß) and two own children and two bonus children (contributed
4753 by Angela).
</p
>
4755 <p
>During the day I am part-time employed as a system administrator
4756 and part-time working as an IT consultant. The consultancy work
4757 touches free software topics wherever and whenever possible. During
4758 the nights I am a free software developer. In the gaps I also train in
4759 becoming an osteopath.
</p
>
4761 <p
>Starting in
2010 we (Andreas Buchholz, Angela Fuß, Mike Gabriel)
4762 have set up a free software project in the area of Kiel that aims at
4763 introducing free software into schools. The project
's name is
4764 "IT-Zukunft Schule
" (IT future for schools). The project links IT
4765 skills with communication skills.
</p
>
4767 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4768 project?
</strong
></p
>
4770 <p
>While preparing our own customised Linux distribution for
4771 "IT-Zukunft Schule
" we were repeatedly asked if we really wanted to
4772 reinvent the wheel. What schools really need is already available,
4773 people said. From this impulse we started evaluating other Linux
4774 distributions that target being used for school networks.
</p
>
4776 <p
>At the end we short-listed two approaches and compared them: a
4777 commercial Linux distribution developed by a company in Bremen,
4778 Germany, and Skolelinux / Debian Edu. Between
12/
2010 and
03/
2011 we
4779 went to several events and met people being responsible for marketing
4780 and development of either of the distributions. Skolelinux / Debian
4781 Edu was by far much more convincing compared to the other product that
4782 got short-listed beforehand--across the full spectrum. What was most
4783 attractive for me personally: the perspective of collaboration within
4784 the developmental branch of the Debian Edu project itself.
</p
>
4786 <p
>In parallel with this, we talked to many local and not-so-local
4787 people. People teaching at schools, headmasters, politicians, data
4788 protection experts, other IT professionals.
</p
>
4790 <p
>We came to two conclusions:
</p
>
4792 <p
>First, a technical conclusion: What schools need is available in
4793 bits and pieces here and there, and none of the solutions really fit
4794 by
100%. Any school we have seen has a very individual IT setup
4795 whereas most of each school
's requirements could mapped by a standard
4796 IT solution. The requirement to this IT solution is flexibility and
4797 customisability, so that individual adaptations here and there are
4798 possible. In terms of re-distributing and rolling out such a
4799 standardised IT system for schools (a system that is still to some
4800 degree customisable) there is still a lot of work to do here
4801 locally. Debian Edu / Skolelinux has been our choice as the starting
4804 <p
>Second, a holistic conclusion: What schools need does not exist at
4805 all (or we missed it so far). There are several technical solutions
4806 for handling IT at schools that tend to make a good impression. What
4807 has been missing completely here in Germany, though, is the enrolment
4808 of people into using IT and teaching with IT.
"IT-Zukunft Schule
"
4809 tries to provide an approach for this.
</p
>
4811 <p
>Only some schools have some sort of a media concept which explains,
4812 defines and gives guidance on how to use IT in class. Most schools in
4813 Northern Germany do not have an IT service provider, the school
's IT
4814 equipment is managed by one or (if the school is lucky) two (admin)
4815 teachers, most of the workload these admin teachers get done in there
4816 spare time.
</p
>
4818 <p
>We were surprised that only a very few admin teachers were
4819 networked with colleagues from other schools. Basically, every school
4820 here around has its individual approach of providing IT equipment to
4821 teachers and students and the exchange of ideas has been quasi
4822 non-existent until
2010/
2011.
</p
>
4824 <p
>Quite some (non-admin) teachers try to avoid using IT technology in
4825 class as a learning medium completely. Several reasons for this
4826 avoidance do exist.
</p
>
4828 <p
>We discovered that no-one has ever taken a closer look at this
4829 social part of IT management in schools, so far. On our quest journey
4830 for a technical IT solution for schools, we discussed this issue with
4831 several teachers, headmasters, politicians, other IT professionals and
4832 they all confirmed: a holistic approach of considering IT management
4833 at schools, an approach that includes the people in place, will be new
4834 and probably a gain for all.
</p

4836 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4837 Edu?
</strong
></p
>
4839 <p
>There is a list of advantages: international context, openness to
4840 any kind of contributions, do-ocracy policy, the closeness to Debian,
4841 the different installation scenarios possible (from stand-alone
4842 workstation to complex multi-server sites), the transparency within
4843 project communication, honest communication within the group of
4844 developers, etc.

4853 client installations on top of a plain vanilla Debian installation
4854 should become possible sometime in the near future, one could think
4855 about splitting the very complex package debian-edu-config into
4856 several portions (to make it easier for new developers to
4857 contribute).
</p

4859 <p
>Another issue I see is that we (as Debian Edu developers) should
4860 find out more about the network of people who do the marketing for
4861 Debian Edu / Skolelinux. There is a very active group in Germany
4862 promoting Skolelinux on the bigger Linux Days within Germany. Are
4863 there other groups like that in other countries? How can we bring
4864 these marketing people together (marketing group A with group B and
4865 all of them with the group of Debian Edu developers)? During the last
4866 meeting of the German Skolelinux group, I got the impression of people
4867 there being rather disconnected from the development department of
4868 Debian Edu / Skolelinux.

4913 <p

>Who are you, and how do you spend your days?

></p

4915 <p
>I am a teacher from Germany, and my subjects are Geography,
4916 Mathematics, and Computer Science (
"Informatik
"). During the past
12
4917 years (since
2000), I have been working for a comprehensive (and soon,
4918 also inclusive) school leading to all kind of general levels, such as
4919 O- or A-level (
"Abitur
"). For quite as long, I
've been taking care of
4920 our computer network.
</p
>
4922 <p
>Now, in my early
40s, I enjoy the privilege of spending a lot of my
4923 spare time together with my wife, our son (
3 years) and our daughter
4924 (
4 months).
</p
>
4926 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4927 project?
</strong
></p
>
4929 <p
>We had tried different Linux based school servers, when members of
4930 my local Linux User Group (LUG OWL) detected Skolelinux. I remember
4931 very well, being part of a party celebrating the Linux New Media Award
4932 (
"Best Newcomer Distribution
", also nominated: Ubuntu) that was given
4933 to Skolelinux at Linux World Exposition in Frankfurt,
2005 (IIRC). Few
4934 months later, I had the chance to join a developer meeting in Ulsrud
4935 (Oslo) and to hand out the award to Knut Yrvin and others. For more
4936 than
7 years, Skolelinux is part of our schools infrastructure, namely
4937 our main server (tjener), one LTSP (today without thin clients), and
4938 approximately
50 work stations. Most of these have the option to boot a
4939 locally installed Skolelinux image. As a consequence, I joined quite
4940 a few events dealing with free software or Linux, and met many Debian
4941 (Edu) developers. All of them seemed quite nice and competent to me,
4942 one more reason to stick to Skolelinux.
</p

4944 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4945 Edu?
</strong
></p
>
4947 <p
>Debian driven, you are given all the advantages of a community
4948 project including well maintained updates. Once, you are familiar with
4949 the network layout, you can easily roll out an entire educational
4950 computer infrastructure, from just one installation media. As only
4951 free software (FOSS) is used, that supports even elderly hardware,
4952 up-sizing your IT equipment is only limited by space (i.e. available
4953 labs). Especially if you run a LTSP thin client server, your
4954 administration costs tend towards zero.
</p
>
4956 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
4957 Edu?
</strong
></p
>
4959 <p
>While Debian
's stability has loads of advantages for servers, this
4960 might be different in some cases for clients: Schools with unlimited
4961 budget might buy new hardware with components that are not yet
4962 supported by Debian stable, or wish to use more recent versions of
4963 office packages or desktop environments. These schools have the
4964 option to run Debian testing or other distributions - if they have the
4965 capacity to do so. Another issue is that Debian release cycles
4966 include a wide range of changes; therefor a high percentage of human
4967 power seems to be absorbed by just keeping the features of Skolelinux
4968 within the new setting of the version to come. During this process,
4969 the cogs of Debian Edu are getting more and more professional,
4970 i.e. harder to understand for novices.
</p

4972 <p
><strong
>Which free software do you use daily?
</strong
></p
>
4974 <p
>LibreOffice, Wikipedia, Openstreetmap, Iceweasel (Mozilla Firefox),
4975 KMail, Gimp, Inkscape - and of course the Linux Kernel (not only on
4976 PC, Laptop, Mobile, but also our SAT receiver)
</p
>
4978 <p
><strong
>Which strategy do you believe is the right one to use to
4979 get schools to use free software?
</strong
></p
>
4983 <li
>Support computer science as regular subject in schools to make
4984 people really
"own
" their hardware, to make them understand the
4985 difference between proprietary software products, and free software
4986 developing.
</li
>
4988 <li
>Make budget baskets corresponding: In Germany
's public schools
4989 there are more or less fixed budgets for IT equipment (including
4990 licenses), so schools won
't benefit from any savings here. This
4991 privilege is left to private schools which have consequently a large
4992 share among German Skolelinux schools.
</li
>
4994 <li
>Get free software in the seminars where would-be teachers are
4995 trained. In many cases, teachers
' software customs are respected by
4996 decision makers rather than the expertise of any IT experts.
</li
>
4998 <li
>Don
't limit ourself to free software run natively. Everybody uses
4999 free software or free licenses (for instance Wikipedia), and this
5000 general concept should get expanded to free educational content to be
5001 shared world wide (school books e.g.).
</li
>
5003 <li
>Make clear where ever you can that the market share of free (libre)
5004 office suites is much above
20 p.c. today, and that you pupils don
't
5005 need to know the
"ribbon menu
" in order to get employed.
</li
>
5007 <li
>Talk about the difference between freeware and free software.
</li
>
5009 <li
>Spread free software, or even collections of portable free apps
5010 for USB pen drives. Endorse students to get a legal copy of
5011 Libreoffice rather than accepting them to use illegal serials. And
5012 keep sending documents in ODF formats.

5031 gledelig overrasket da han dukket opp i Skolelinux-prosjektet etter å
5032 ikke ha sett noe til ham på mange år.

5034 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p

5036 <p
>Jeg er utdannet kokk av yrke, og har utøvet yrket i
12 år. Men
5037 etter at ryggen sa takk før seg, studerte jeg nettverksadministrasjon
5038 ved Næringsakademiet i Bergen årene
2008-
2009 slik at jeg kunne
5039 forfølge en av mine største interesser - data. Til daglig jobber jeg
5040 ved
<a href=

5041 ungdomsskole
</a
> med å drifte skolens PC-er. Har også litt
5042 musikkundervisning.
</p
>
5044 <p
>Mitt mål er å bevisstgjøre musikklærene mulighetene med de frie
5045 programmene som finnes i Skolelinux, blant annet Rosegarden.
</p
>
5047 <p
>Har i mange år drevet med musikk og en av grunnen til at Rosegarden
5048 falt i smak for min del, var fordi denne fungere og ligner mest på
5049 Windows-programmet (cubase) jeg jobbet mye med da jeg i mine yngre
5050 dager var «Windows fanatiker». Ble introdusert til Linux av en kompis
5051 av meg for omtrent
14 år siden, og har bare blitt mer og mer glad i
5052 dette operativsystemet.
</p
>
5054 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
5056 <p
>Da jeg ble sykemeldt fra min gamle jobb, og måtte omskoleres,
5057 havnet jeg i
2007 sammen med Viggo Fedreheim på IKT-avdelingen i
5058 Narvik kommune, der ble jeg for første gang introdusert til
5059 Skolelinuxprosjektet.
</p
>
5061 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
5063 <p
>Skolelinux er enkelt å holde i drift og masse flotte programmer som
5064 geogebra, ktouch og kgeografi følger med pakken. Man kan ta i bruk
5065 gamle PC-er igjen, slik at skoler med dårlig råd får opp en brukbar
5066 PC-park. PC-er som er ca
6-
9 år gamle fungere tilfredstillende, bare
5067 de har
512 MB RAM eller mer.
</p
>
5069 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
5071 <p
>Ulempene er at noen av de pedagogiske programmene som lærene ønsker
5072 å bruke fungere dårlig med Linux. Mye pga. av at disse programmene
5073 blir ikke laget til Linuxbaserte operativsystemer.
</p
>
5075 <p
>Video- og bilde-redigering har dessverre en del mangler, mange av
5076 programmene har en tendens til og krasje. Det gjelder blant annet
5077 <a href=
"http://www.kdenlive.org/
">kdenlive
</a
> og
5078 <a href=
"http://www.openshotvideo.com/
">openshot
</a
>, for å nevne
5079 noen. De er ikke stabile nok. Når elevene kommer med filmsnutter de
5080 ønsker og jobbe med, så godtar ikke programmene filene, og når elevene
5081 jobber med redigering bare krasjer programmene uten forvarsel. Det er
5082 for vanskelig å få noe som bare fungerer ut av boksen her. Når en elev
5083 plugger inn et videokamera eller fotoapparat så er det alltid noe som
5084 ikke vil fungere. Programmene godtar ikke format, godtar ikke
5085 kameraet, osv., osv. Det er dessverre med på og dra ned en positiv
5086 opplevelse av bruk av fri programvare.
</p
>
5088 <p
>Man må ofte bruke flere en et video redigerings program før og få
5089 fullført en ønsket oppgave.
</p
>
5091 <p
>Eksempel:
</p
>
5093 <p
>Hvis det ene programmet ikke vil ta i mot videofilen klarer et
5094 annet det, men det programmet som klarer det kan ikke gjøre de samme
5095 oppgavene som det programmet som ikke ville ta i mot filen,
5096 Tilsvarende er det med foto, man må bruke flere programmer for å få
5097 et ferdig resultat. Til dags dato har jeg enda ikke funnet et video-
5098 og fotoprogram som kan tilfredstillende fullføre en oppgave.
</p
>
5100 <p
>Så man kan klare og fullføre en oppgave, men i verste fall må man
5101 innom
3-
4 programmer for å få det til. Så jeg har enda ikke til dags
5102 dato sett at et program fungere
100% til alt.
</p
>
5104 <p
>Det programmet jeg har best erfaring til er
5105 <a href=
"http://cinelerra.org/
">cinelerra
</a
>, men dessverre har det
5106 også tendenser og krasje av og til uten grunn.
</p
>
5108 Lydsystemet kan også være et mareritt. Konkret snakker jeg om når du
5109 bruker for eksempel et smartboard, så følger det med USB-lydkort på
5110 disse. Problemet ligger her i at systemet ikke vil velge rett
5111 lydkort, så man må inn med padevchooser for å sette opp PulseAudio
5112 til og velge at USB-lydkortet skal brukes. Det blir for tungvindt for
5113 lærene, de ønsker at ting skal fungere med en gang. (min løsning på
5114 det problemet ble at jeg måtte deaktivere lydkortet som fantes på
5115 maskinen) men da må man bestandig slå på smartboard-tavla.
5117 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
5119 Programmene jeg bruker mest av er: Rosegarden, jack, qsynth, audacity,
5120 k3b, openttd og libreoffice.
5122 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
5123 skoler til å ta i bruk fri programvare?
</strong
></p
>
5125 Jeg tror det må bevisstgjøring av Skolene til, dvs. reklamere høylytt
5126 og fortelle og vise de andre skolene at frie programvarer faktisk
5127 fungere. Jeg trur faktisk mange ikke vet at det finnes frie

5138 publish another interview with the people behind

">Debian Edu and Skolelinux
</a
>.
5140 This time it is one of our German developers, who have helped out over the
5141 years to make sure both a lot of major but also a lot of the minor
5142 details get right before release.
5144 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
5146 <p
>My name is Jürgen Leibner, I
'm
49 years old and living in
5147 Bielefeld, a town in northern Germany. I worked nearly
20 years as
5148 certified engineer in the department for plant design and layout of an
5149 international company for machinery and equipment. Since
2011 I
'm a
5150 certified technical writer (tekom e.V.) and doing technical
5151 documentations for a steam turbine manufacturer. From April this year
5152 I will manage the department of technical documentation at a
5153 manufacturer of automation and assembly line engineering.
</p
>
5155 <p
>My first contact with linux was around
1993. Since that time I used
5156 it at work and at home repeatedly but not exclusively as I do now at
5157 home since
2006.
</p
>
5159 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5160 project?
</strong
></p
>
5162 <p
>Once a day in the early year of
2001 when I wanted to fetch my
5163 daughter from primary school, there was a teacher sitting in the
5164 middle of
20 old computers trying to boot them and he failed. I helped
5165 him to get them booting. That was seen by the school director and she
5166 asked me if I would like to manage that the school gets all that old
5167 computers in use. I answered:
"Yes
".
</p
>
5169 <p
>Some weeks later every of the
10 classrooms had one computer
5170 running Windows98. I began to collect old computers and equipment as
5171 gifts and installed the first computer room with a peer-to-peer
5172 network. I did my work at school without being payed in my spare time
5173 and with a lot of fun. About one year later the school was connected
5174 to Internet and a local area network was installed in the school
5175 building. That was the time to have a server and I knew it must be a
5176 Linux server to be able to fulfil all the wishes of the teachers and
5177 being able to do this in a transparent and economic way, without extra
5178 costs for things like licence and software. So I searched for a
5179 school server system running under Linux and I found a couple of
5180 people nearby who founded
'skolelinux.de
'. It was the Skolelinux
5181 prerelease
32 I first tried out for being used at the school. I
5182 managed the IT of that school until the municipal authority took over
5183 the IT management and centralised the services for all schools in
5184 Bielefeld in December of
2006.

>What do you see as the advantages of Skolelinux/Debian
5187 Edu?
</strong

>
5189 <p
>When I
'm looking back to the beginning, there were other advantages
5190 for me as today.
</p
>
5192 <p
>In the past there were advantages like:
</p
>
5196 <li
>I don
't need to buy it so it generates no costs to the school as
5197 they had little money to spent for computers and software.
</li
>
5199 <li
>It has a licence which grands all rights to use it without
5202 <li
>It was more able to fit all requirements of a server system for
5203 schools than a Microsoft server system, even if there are only Windows
5204 clients because of it
's preconfigured overall concept of being a
5205 infrastructure solution and community for schools, not only a

>I was able to configure the server to the needs of the
5211 </ul
></p
>
5213 <p
>Today some of the advantages has been lost, changed or new ones
5214 came up in this way:
</p
>
5218 <li
>Most schools here do have money to buy hardware and software
5221 <li
>They are today mostly managed from central IT departments which
5222 have own concepts which often do not fit to Debian Edu concepts
5223 because they are to close to Microsoft ideology.
</li
>
5225 <li
>With the Squeeze version of Debian Edu which now uses GOsa² for
5226 management I feel more able to manage the daily tasks than with the
5227 interfaces used in the past.
</li
>
5229 <li
>It is more modular than in the past and fits even better to the
5230 different needs.
</li
>
5232 <li
>The documentation is usable and gets better every day.
</li
>
5234 <li
>More people than ever before are using Debian Edu all over the
5235 world and so the community, which is an very important part I think,
5236 is sharing knowledge and minds.
</li
>
5238 <li
>Most, maybe all, of the technical requirements for schools are
5239 solved today by Debian Edu.

5248 <li
>There are too few IT companies able to integrate Debian Edu into
5249 their product portfolio for serving schools with concepts or even
5250 whole municipality areas.
</li

5252 <li
>Debian Edu has beside other free and open software projects not
5253 enough lobbyists which promote free and open software to

5263 computer. On my laptop I use Debian testing/sid. The applications I
5264 use on my laptop and my desktop are Open/Libre-office, Iceweasel,
5265 KMail, DigiKam, Amarok, Dolphin, okular and all the other programs I
5266 need from the KDE environment. On console I use newsbeuter, mutt,
5267 screen, irssi and all the other famous and useful tools.
</p

5269 <p

5270 and mutt over ssh on the console, file services with samba, NFS,
5271 rsync, web services with apache, moinmoin-wiki, multimedia services
5272 with gallery2 and mediatomb and database services with MySQL for me

>Da jeg googlet etter noe annet kom jeg tilfeldigvis over
5290 <a href=
"http://www.duo.uio.no/sok/work.html?WORKID=
58309">en
5291 hovedfagsoppgave
</a
> ved Universitetet i Oslo som diskuterer verdien
5292 av GPLs fire friheter for brukerne av IT-systemer. Jeg ble fascinert
5293 over det som presenteres der. Her er sammendraget:
</p
>
5295 <p
><blockquote
>
5297 <p
>Motivasjonen til å skrive denne oppgaven er en personlig undring
5298 over hvorfor det primært, og ofte eksklusivt, fokuseres på det
5299 økonomiske aspektet ved utredninger om fri programvare er et godt valg
5300 for det offentlige. Fri og produsenteid programvare bygger på
5301 fundamentalt forskjellige ideologier som kan ha implikasjoner utover
5302 økonomiske kostnader. Kunnskapskulturen som er med på å definere fri
5303 programvare er basert på åpenhet, og er en verdi i seg selv.
</p
>
5305 <p
>Oppgavens tema er programvarelisensen GPL og frihet. GPL-lisensiert
5306 programvare gir visse friheter i forhold til produsenteid
5307 programvare. Mitt spørsmål er om, og eventuelt i hvilken utstrekning,
5308 disse frihetene blir benyttet av ulike brukere og hvordan de
5309 manifesterer seg for disse brukerne. Sentrale spørsmål i oppgaven
5313 <li
>Hvordan fordeles handlekraft gjennom lisensieringen av programvaren?
</li
>
5314 <li
>Hvilke konsekvenser har programvarelisensen for de ulike brukere?
</li
>
5317 <p
>Fri programvare gir blant annet brukeren mulighet til å studere og
5318 modifisere kildekoden. Denne formen for frihet erverves gjennom
5319 kunnskap og krever at brukeren også er en ekspert. Hva skjer med
5320 frihetene til GPL når sluttbrukeren er en annen? Dette diskuteres i
5321 dialog med informantene.
</p
>
5323 <p
>Jeg har i denne oppgaven samlet inn intervjudata fra IKT-ansvarlige
5324 ved grunnskolene i Nittedal kommune, driftsansvarlig og IKT-veilederen
5325 for skolene i kommunen, samt IKT-koordinator for utdanning i Akershus
5326 fylkeskommune og bokmåloversettere av OpenOffice.org. Den empiriske
5327 delen av oppgaven er delt inn i to seksjoner; den første omhandler
5328 operativsystemet Skolelinux, den andre kontorprogrampakken
5329 OpenOffice.org.
</p
>
5331 <p
>Som vi vil se gir GPL lokal frihet og kontroll gjennom omfordeling
5332 av makt fra produsent til bruker. Brukerens makt analyseres gjennom
5333 begrepene brukermedvirkning og handlingsfrihet. Det blir også lagt
5334 vekt på strukturelle forhold rundt bruken av teknologi, og spesielt de
5335 økonomiske begrepene nettverkseksternaliteter, innlåsing og
5336 stiavhengighet. Dette er begreper av spesiell nytte når objektet som
5337 omsettes eller distribueres er et kommunikasjonsprodukt, fordi verdien
5338 til et slikt gode for en potensiell bruker avhenger av antall
5339 eksisterende brukere av godet. I tilknytning til denne problematikken
5340 inneholder oppgaven også en diskusjon rundt åpne standarder og
5343 <p
>Oppgaven konkluderer med at de «fire frihetene» som GPL-lisensen er
5344 laget for å beskytte er av avgjørende betydning for bruken av
5345 OpenOffice.org og Skolelinux, i Akershus fylkeskommune såvel som i
5346 skolene i Nittedal. Distribusjonen av handlekraft er ikke helt
5347 symmetrisk. Det er først og fremst de profesjonelle utviklerne i
5348 Skolelinux som direkte kan nyttiggjøre seg friheten til å endre kode,
5349 mens en sluttbruker som Nittedal kommune nyttiggjør seg den økonomiske
5350 friheten til å kunne distribuere programmene. Det er imidlertid også
5351 slik at ingen aktør klarer seg uten alle disse «frihetene».

>Behind
<a href=
"http://www.skolelinux.org/
">Debian Edu and
5368 Skolelinux
</a
> there are a lot of people doing the hard work of
5369 setting together all the pieces. This time I present to you Andreas
5370 Mundt, who have been part of the technical development team several
5371 years. He was also a key contributor in getting GOsa and Kerberos set
5372 up in the recently released
5373 <a href=
"http://wiki.debian.org/DebianEdu/Documentation/Squeeze

5374 Edu Squeeze
</a
> version.
</p
>
5376 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
5378 <p
>My name is Andreas Mundt, I grew up in south Germany. After
5379 studying Physics I spent several years at university doing research in
5380 Quantum Optics. After that I worked some years in an optics company.
5381 Finally I decided to turn over a new leaf in my life and started
5382 teaching
10 to
19 years old kids at school. I teach math, physics,
5383 information technology and science/technology.
</p
>
5385 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5386 project?
</strong
></p
>
5388 <p
>Already before I switched to teaching, I followed the Debian Edu
5389 project because of my interest in education and Debian. Within the
5390 qualification/training period for the teaching, I started
5391 contributing.
</p
>
5393 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5394 Edu?
</strong
></p
>
5396 <p
>The advantages of Debian Edu are the well known name, the
5397 out-of-the-box philosophy and of course the great free software of the
5398 Debian Project!
</p
>
5400 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
5401 Edu?
</strong
></p
>
5403 <p
>As every coin has two sides, the out-of-the-box philosophy has its
5404 downside, too. In my opinion, it is hard to modify and tweak the
5405 setup, if you need or want that. Further more, it is not easily
5406 possible to upgrade the system to a new release. It takes much too
5407 long after a Debian release to prepare the -Edu release, perhaps
5408 because the number of developers working on the core of the code is
5409 rather small and often busy elsewhere.
</p
>
5411 <p
>The
<a href=
"http://wiki.debian.org/DebianLAN
">Debian LAN
</a
>
5412 project might fill the use case of a more flexible system.
</p
>
5414 <p
><strong
>Which free software do you use daily?
</strong
></p
>
5416 <p
>I am only using non-free software if I am forced to and run Debian
5417 on all my machines. For documents I prefer LaTeX and PGF/TikZ, then
5418 mutt and iceweasel for email respectively web browsing. At school I
5419 have Arduino and Fritzing in use for a micro controller project.
</p
>
5421 <p
><strong
>Which strategy do you believe is the right one to use to
5422 get schools to use free software?
</strong
></p
>
5424 <p
>One of the major problems is the vendor lock-in from top to bottom:
5425 Especially in combination with ignorant government employees and
5426 politicians, this works out great for the
"market-leader
". The school
5427 administration here in Baden-Wuerttemberg is occupied by that vendor.
5428 Documents have to be prepared in non-free, proprietary formats. Even
5429 free browsers do not work for the school administration. Publishers
5430 of school books provide software only for proprietary platforms.
</p
>
5432 <p
>To change this, political work is very important. Parts of the
5433 political spectrum have become aware of the problem in the last years.
5434 However it takes quite some time and courageous politicians to
'free
'
5435 the system. There is currently some discussion about
"Open Data
" and
5436 "Free/Open Standards
". I am not sure if all the involved parties have
5437 a clue about the potential of these ideas, and probably only a
5438 fraction takes them seriously. However it might slowly make free
5439 software and the philosophy behind it more known and popular.

5506 <a href=

">Skolelinux Drift AS
</a
> on speeding
5507 up a
<a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>
5508 Lenny installation using LTSP diskless workstations, and in the
5509 process I discovered something very surprising. The reason the KDE
5510 menu was responding slow when using it for the first time, was mostly
5511 due to the way KDE find application icons. I discovered that showing
5512 the Multimedia menu would cause more than
20 000 IP packages to be
5513 passed between the LTSP client and the NFS server. Most of these were
5515 NFS LOOKUP calls, resulting in a NFS3ERR_NOENT response. Because the
5516 ping times between the client and the server were in the range
2-
20
5517 ms, the menus would be very slow. Looking at the strace of kicker in
5518 Lenny (or plasma-desktop i Squeeze - same problem there), I see that
5519 the source of these NFS calls are access(
2) system calls for
5520 non-existing files. KDE can do hundreds of access(
2) calls to find
5521 one icon file. In my example, just finding the mplayer icon required
5522 around
230 access(
2) calls.
</p
>
5524 <p
>The KDE code seem to search for icons using a list of icon
5525 directories, and the list of possible directories is large. In
5526 (almost) each directory, it look for files ending in .png, .svgz, .svg
5527 and .xpm. The result is a very slow KDE menu when /usr/ is NFS
5528 mounted. Showing a single sub menu may result in thousands of NFS
5529 requests. I am not the first one to discover this. I found a
5530 <a href=
"https://bugs.kde.org/show_bug.cgi?id=
211416">KDE bug report
5531 from
2009</a
> about this problem, and it is still unsolved.
</p
>
5533 <p
>My solution to speed up the KDE menu was to create a package
5534 kde-icon-cache that upon installation will look at all .desktop files
5535 used to generate the KDE menu, find their icons, search the icon paths
5536 for the file that KDE will end up finding at run time, and copying the
5537 icon file to /var/lib/kde-icon-cache/. Finally, I add symlinks to
5538 these icon files in one of the first directories where KDE will look
5539 for them. This cut down the number of file accesses required to find
5540 one icon from several hundred to less than
5, and make the KDE menu
5541 almost instantaneous. I
'm not quite sure where to make the package
5542 publicly available, so for now it is only available on request.
</p
>
5544 <p
>The bug report mention that this do not only affect the KDE menu
5545 and icon handling, but also the login process. Not quite sure how to
5546 speed up that part without replacing NFS with for example NBD, and
5547 that is not really an option at the moment.

5600 <p
>The first information about Skolelinux must have come to my
5601 attention years ago and somehow related to LTSP (Linux Terminal Server
5602 Project). At school, we had set up a network at the beginning of
1997
5603 using Suse Linux on the desktop, replacing a Novell network. Since
5604 2002, we used old machines from the city council of Dortmund as thin
5605 clients (LTSP, later Ubuntu/Lessdisks) cause new hardware was out of
5606 reach. At home I
'm using Debian since years and - subscribed to the
5607 Debian news letter - heard from time to time about Skolelinux. About
5608 two years ago I proposed to replace the (somehow undocumented and only
5609 known to me) system at school by a well known Debian based system:
5610 Skolelinux.
</p
>
5612 <p
>Students and teachers appreciated the new system because of a
5613 better look and feel and an enhanced access to local media on thin
5614 clients. The possibility to alter and/or reset passwords using a GUI
5615 was welcomed, too. Being able to do administrative tasks using a GUI
5616 and to easily set up workstations using PXE was of very high value for
5617 the admin teachers.

's open source, easy to set up, stable and flexible due to it
's
5623 Debian base. It integrates LTSP out-of-the-box. And it is documented!
5624 So it was a perfect choice.
</p
>
5626 <p
>Being open source, there are no license problems and so it
's
5627 possible to point teachers and students to programs like
5628 OpenOffice.org, ViewYourMind (mind mapping) and The Gimp. It
's of
5629 high value to be able to adapt parts of the system to special needs of
5630 a school and to choose where to get support for this.

5668 undersøkelsen Monitor
2011 som er laget på oppdrag fra
5669 Kunnskapsdepartementet. Dette har ført til debatt om PC-tilgangen i
5670 skolen, og om de med Linux i skolen gjør det bedre bedre eller
5671 dårligere enn snittet i landet.
</p
>
5673 <p
>Nå har vi tallene. Skoler med Linux har
36% større PC-tetthet en
5674 landsgjennomsnittet. På spørsmål hvorfor skoler med Linux har større
5675 PC-tetthet, observerer Paul Reidar Løsnesløkken som er IKT-konsulent i
5676 Nord-Odal:
</p

5678 <p
><blockquote
>"Vi erfarer at klienter med Skolelinux har god funksjon
5679 til de er
8 til
10 år gamle. Dette er omtrent dobbelt så lenge som
5680 andre løsninger, og skolene får mer datautstyr for
5681 pengene.
"</blockquote
></p
>
5683 <p
>Undersøkelsen baserer seg på
56 skoler som har gjort det offentlig
5684 at de kjører Skolelinux eller annen Linux-utgave. De kan også ha PC-er
5685 med Windows i skolenettet. Når en sammenligner PC-tetthetene på
5686 skolene i kommunene Flora, Harstad, Kongsvinger, Narvik, Nittedal,
5687 Nord-Odal og Randaberg, er det i snitt
2,
28 elev pr. PC på skolene med
5688 Linux. På landsbasis er det
3.11 elev per PC i grunnskolen, i følge
5689 side
95 i Monitor-rapporten for
2011. Målingen viser dermed
36% større
5690 PC-tetthet i skoler med Linux.

>Skolelinux har til hensikt å gi alle barn full tilgang til
5695 skoleaktuelle dataprogram på sitt eget morsmål. Derfor følger det med
5696 godt over
100 skoleaktuelle programmene laget for læring. De fleste
5697 programmene er oversatt til over
50 språk. Elevene skal også kunne
5698 studere alle sider av dataprogrammene. Derfor følger også kildekode
5699 med. Elever med interesse kan lære av eksperter som har laget
5700 systemet. Dette med enkelt programmering i læreprogram som KTurtle,
5701 til profesjonelle verktøy som Qt Creator eller Java.
</p

5703 <p
>Skolelinux er laget for sentralisert drift, der alt teknisk
5704 administrasjon av alle skolene kan gjøres sentralt fra kommunehuset
5705 eller sentralt i en region. F.eks. drifter to-tre personer
70.000
5706 skoledatamaskiner på
200 skoler i delstaten Extremadura i
5707 Spania. Etter velykket bruk av Debian Edu i skolen, legger delstaten
5708 over til Debian på
40.000 datamaskiner i administrasjonen. Det er idag
5709 mange selskap som tilbyr profesjonell støtte til innføring og drift i
5710 Norge og verden.

5747 <description><p
>I serien med intervjuer av folk i
5748 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet, får vi
5749 denne gangen høre fra en IKT-ansvarlig som har brukt Skolelinux i
5750 mange år, og vært storfornøyd med erfaringene så langt.
</p
>
5752 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
5754 <p
>Mitt navn er Roy-Arne Myhre og jeg er
42 år. Jeg er ansatt hos
5755 <a href=
"http://www.sandskole.no/
">Sand skole
</a
> (Balsfjord kommune)
5756 og har stort sett vært det siden
1990. Jeg er IKT ansvarlig ved
5757 skolen i
40% stilling –
10% undervisning – musikk.
</p
>
5759 <p
>Ved skolen er det ca
100 elever og ca
18 lærere +
4 assistenter i
5760 hele og delte stillinger. Alle lærerne har bærbar PC (dessverre med
5761 Win Vista) – assistenter har tilgang til egne. Vi benytter Fronter i
5762 det daglige arbeidet. Vi har ca
90 elevmaskiner som fungerer til
5763 daglig opp mot Linux server (XFCE) som driftes av
5764 <a href=
"http://www.bzz.no/
">BzzWare AS
</a
> via nett. Maskinparken
5765 består kun av brukt utstyr for elevene – og noe av dette begynner å
5766 bli vel gammelt selv som halvtykke klienter.
</p
>
5768 <p
><strong
>Hvordan kom du i kontakt med
5769 Skolelinux-prosjektet?
</strong
></p
>
5771 <p
>Vi kom første gang i kontakt med Skolelinux rundt
1997. Den gang
5772 var det oppstart-disketter i hver maskin, ikke mulighet for lyd og
5773 video, gamle nettverkskort og mye plundring. Vi hadde en ihuga
5774 forelder med som pådriver, forsker og inspirator for hele opplegget.
5775 Selv ante jeg knapt at Skolelinux fantes, men han var av den
5776 utforskende typen, og fikk både meg og skolelederen i trua på at dette
5777 var ting som kunne fungere. Etter dette har det gått gradvis
5778 framover; flere maskiner er hentet inn gjennom bl.a
5779 <a href=
"http://www.greentech.no/
">Greentech
</a
> og utrangert utstyr
5780 fra høgskole / Avinor og private givere. Når maskinene ble for trege
5781 for nye Windows-versjoner, sto vi klare til å putte dem i nettverket
5782 vårt. Dette betyr at vi i dag har
1:
1 dekning av maskiner på
5783 ungdomstrinnet og bedre enn
1:
2 på barnetrinnet. Dette er vi veldig
5784 fornøyd med, og vi kan ikke se for oss hverdagen som ville vært
5785 alternativet ved bruk av Windows med sine lisenser pr. Bruker/maskin.
5786 Da ville vi nok vært tilbake til
1-
2 maskiner pr klasserom med de
5787 negative konsekvenser det ville hatt for undervisningsformene våre. Vi
5788 kan ha en hel klasse i prosjektjobbing eller individuell jobbing
5789 samtidig – vi kan avholde tentamen og eksamen uten
5790 logistikkproblemer.
</p
>
5792 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
5794 Hvor skal jeg begynne... Stabiliteten er et nøkkelord - det bare
5795 virker. Har du først fått en server med Skolelinux opp og gå, så må
5796 det en maskinarefeil eller sabotasje til for å stoppe den. Det at man
5797 kan bruke eldre maskiner som normalt sett ville gått på dynga, er også
5798 glimrende - billig for skoler med dårlig økonomi og bra for miljøet
5799 siden vi gjenbruker utstyr i stedet for å skaffe nytt. Vi ville aldri
5800 hatt mulighet til å operere med det maskinantallet vi har pr i dag
5801 hvis det ikke var for Skolelinux - så tilgjengelighet er et annet
5802 nøkkelord. Et tredje moment er sikkerhet og brukertilgang. Alle
5803 brukerer opererer med egne brukernavn og passord, samt egne
5804 brukerområder som kan tilpasses for både enbrukertilgang og for
5805 samarbeid med andre.
5807 Elever har godt av å se at det finnes andre alternativer enn de som
5808 storindustrien selger på lisensbasis - på den måten trenes de opp til
5809 å se flere muligheter og å foreta valg ut fra flere opsjoner.
5811 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
5813 <p
>Ulempene med Skolelinux er nok utbredelsen og mangelen på kjennskap
5814 til dette i skolenorge. De som skal ta økonomiske avgjørelser rynker
5815 på nesen og vil gå for det kjente og «sikre» selv om det koster mye
5816 mer. Man får rett og slett litt hetta av å ikke kunne noe – og unngår
5817 dette for enhver pris.
</p
>
5819 <p
>I tillegg er mye av linux-systemet administrert av tekstkommandoer
5820 og er lite intuitiv/visuell for oss som ikke er «inne i»
5821 kildekodene». Så problemet er nok mye godt at de som
5822 utarbeider/drifter Skolelinux ikke helt klarer å sette seg ned på
5823 skoleadministratorens nivå når det gjelder problemer og
5824 utfordringer. Men dette er nok en utfordring alle administratorer
5825 sliter med uansett OS.
</p
>
5827 <p
>Derfor har vi valgt å støtte oss til BzzWare AS for assistanse i
5828 drifta slik at jeg har kunnet konsentrere meg mer om kabling, skifting
5829 av komponenter, veiledning av lærere og elever, vedlikehold av
5830 skrivere og annen daglig drift.
</p
>
5832 <p
>Elevene mestrer Skolelinux helt fint. Så lenge Internett
5833 (Iceweasel) og Libreoffice (Openoffice) fungerer er
90% av
5834 skolehverdagen velfungerende. I tillegg brukes jo en del av den
5835 pedagogiske programpakken bla. i forhold til matematikk og geografi,
5836 men det er såpass mye bra på nett om dagen, så disse programmene er
5837 mer som krydder å regne.
</p
>
5839 <p
>Jeg skulle ønske neste versjon av Skolelinux kunne komme litt
5840 mindre stappet med programmer, for halvparten blir aldri brukt, eller
5841 fungerer ikke uansett. Hva med et pedagogisk panel av lærere/IKT
5842 ansvarlige som kunne sagt: disse programmene skal være standard, så
5843 får resten være slike man kan legge til ved behov – det kan lett bli
5844 en jungel å bevege seg i.
</p
>
5846 <p
>Jeg ønsker meg også en mer grafisk versjon av
5847 <a href=
"http://bzz.no/lwat/trac/trac.cgi
">Lwat
</a
> hvor man kan krysse
5848 ut de som f.eks ikke skal ha internett-tilgang en dag pga
5849 eksamen/tentamen, samt en noe enklere brannmurløsning hvor man kan
5850 stenge for en del (få) sider på en enkel måte. Jeg liker godt
5851 Skolelinux sin ideologi om at filteret skal trenes i hodet på eleven –
5852 men av og til skulle jeg ønske at f.eks Facebook og Youtube kunne vært
5853 koblet vekk en periode for å få bedre utnyttelse av tid og
5854 ressurser. Disse to nettstedene er nok mye av årsaken til at mange
5855 lærere holder igjen databruken noe mer enn man kunne ønske.
</p
>
5857 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
5859 Jeg benytter nesten bare fri programvare til daglig. LibreOffice,
5860 Iceweasel (Firefox), Thunderbird til e-post og Gimp til
5861 bildebehandling. Vi har PHP-Nuke-oppsatt hjemmeside. Det eneste som
5862 jeg ikke har fått helt til enda er videoredigering - her må man vel
5863 innrømme at Mac er hakket over, men da er vi igjen over på å se hva
5864 som egner seg best, og ta valg ut fra det. Folk flest lever i
5865 villfarelsen om at regneark HETER Excel og tekstbehandling HETER
5866 Word. Dette er en misforståelse som jeg bruker mye energi på å
5867 diskutere og
"åpne sinn
" på Microsoft-slaver. Dessverre er det mange
5868 IKT-ansvarlige som også har låst seg på at det eneste saliggjørende er
5869 Bill G sine produkter.
5871 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
5872 skoler til å ta i bruk fri programvare?
</strong
></p
>
5874 <p
>For å komme lenger i utbredelsen av Skolelinux tror jeg det må mer
5875 fram i nasjonale medier, samt komme bedre fram hva økonomien i dette
5876 valget vil være – samt mulighetene. Fri programvare er en berikelse og
5877 gjør oss i stand til å utføre arbeidet i skolen uten å måtte legge
5878 igjen tusener på tusener i Bill Gates lomme.. Få ETT nettsted med
5879 forståelig veiledning av installasjon/oppgradering og ETT forum med
5880 konkrete feilrettinger og problemer, så tror jeg vi kunne kommet et
5881 par skritt framover. Ellers tror jeg bare at ildsjelene må fortsette å
5882 skinne – kanskje flere enn oss følger etter på veien.

>Den siste uka har det vært en del skriverier om hvor store

">oppslaget
5920 i Digi
</a
>. Diskusjonen fikk meg til å bli litt nysgjerrig på om
5921 Linux-skoler har større PC-tettet enn snittet i landet. Grunnlaget
5922 for diskusjonen har vært undersøkelsen
5923 <a href=
"https://iktsenteret.no/ressurser/monitor-
2011-skolens-digitale-tilstand
">Monitor
5924 2011</a
>, som bruker informasjon fra
5925 <a href=
"https://www.wis.no/gsi
">Grunnskolens Informasjonssystem
</a
>
5926 (GSI). GSI-data kan lastes ned fra web og jeg lastet ned en Excel-fil
5927 (intet åpen standard-valg tilgjengelig) med navn på alle skoler,
5928 hvilke kommune de befinner seg i og hvor mange elever pr. elev-PC de
5929 har rapportert inn. For å få en ide om svaret trenger jeg deretter å
5930 vite hvilke skoler i landet som bruker Linux, slik at jeg kan slå dem
5931 opp i GSI og finne ut hvor stor PC-tetthet de har.
</p
>
5933 <p
>Jeg vet om skoler i Balsfjord, Flora, Harstad, Kongsvinger, Narvik,
5934 Nittedal, Nord-Odal, Randaberg og Sunndal som bruker Skolelinux eller
5935 andre Linux-varianter. Jeg tror det er flere enn de
56 skolene jeg
5936 har klart å identifisere de siste dagene, men har ikke klart å få det
5937 bekreftet med offentlige kilder.
</p
>
5939 <p
>Monitor
2011-rapporteres side
95 forteller at det
"ifølge GSI
5940 (
20120-
2011) er det
3,
11 elever per datamaskin når vi tar med alle
5941 grunnskoler (
1.-
10.trinn)
". For de
56 Linux-skolene jeg har klart å
5942 koble mot informasjon i GSI er det
2,
28 elever per elevdatamaskin,
5943 hvilket betyr at det er
36% høyere PC-tetthet på Linux-skoler enn
5944 landsgjennomsnittet. Linux-skolen med høyest tettet blant de jeg har
5945 notert -skole er Flora ungdomsskule i Flora kommune med
0.82 elev
5946 pr. PC (
482 elever,
588 elevdatamaskiner).
</p
>
5948 <p
>Skolelinux gir datamaskiner lengre levetid, og en kan dermed få
5949 flere operative datamaskiner for samme budsjett, i tillegg til en
5950 rekke andre fordeler. Kan det være forklaringen på forskjellen?
</p
>
5952 <p
>Tallene må tas med en liten klype, da GSI ser ut til å ha endel
5953 feilføringer. Jeg synes i hvert fall en skole med
423 elever og
9
5954 elevmaskiner ser mistenkelig ut. Eller en skole med
346 elever,
0
5955 elevmaskiner, som er et annet ekstremt eksempel jeg fant.

5977 author/trainer while my children attended the school, and I also
5978 contributed to the Schoolforge UK community with the aim of
5979 encouraging UK schools to adopt free/open source software. Five or six
5980 years ago we had about
50 schools interested in some way, but we
5981 weren

5987 <p
>Skolelinux had two representatives at an early Edubuntu meeting in
5988 London which I attended. However at that time our school network had
5989 just been installed using CentOS, LTSP
4 and GNOME. When LTSP
5 came
5990 along we switched to Edubuntu thin client servers so now we have a
5991 mixed environment which includes Windows PCs and student laptops, as
5992 well as their MacBooks and iPads. However, the proprietary systems
5993 have always been rather problematic, and we never built a GUI for the
5994 LDAP server, so when I discovered Skolelinux is configured for all
5995 these things we decided to try it.

6002 goals that Skolelinux is built on: installing Linux on computers which
6003 would otherwise be thrown away, to provide a reliable, secure and
6004 low-cost IT environment for schools. From my own experience I know
6005 that a part-time person can teach and manage a network of about

6029 <p
>That
's a tough question! For very many years UK schools installed
6030 and taught only proprietary software, so that at the highest levels
6031 the notion of
"computer
" means simply
"proprietary office
6032 applications
". However, schools today are experiencing budget
6033 constraints, and many are having to think hard about upgrading Windows
6034 XP. At the same time, we have students showing teachers how to use
6035 iPads, MacBooks and Android, so the choice of operating system is no
6036 longer quite so automatic. What is more, our government at last
6037 realised that we need people with programming skills, so they
're
6038 putting coding back in the curriculum! And it
's encouraging that the
6039 first
10,
000 Raspberry Pi units sold out in
2 hours.

6041 <p
>I don
't really know what strategy is going to get UK schools to use
6042 free software, but building an active community of Skolelinux/Debian
6043 Edu users in this country has to be part of it.

>Documentation in Debian Edu is provided in several languages, and
6053 it is important to make it both easy to contribute and to keep the
6054 translated versions in sync. To do this we have come up with what we
6055 believe is a very efficient work flow.
</p
>
6059 <li
>The documentation is written in a
6060 <a href=
"http://moinmo.in
">moinmoin wiki
</a
> (see for example
6061 <a href=
"http://wiki.debian.org/DebianEdu/Documentation/Squeeze
">the
6062 Squeeze release manual
</a
>) with support for exporting the content as
6063 docbook XML.
</li
>
6065 <li
>This docbook document is given to po4a to extract a gettext style
6066 .pot file with the content, which in turn is used to create .po files
6067 with the translated text.
</li
>
6069 <li
>The .po files are given to translators, and they can always tell
6070 which part of the original wiki document is new or changed. They can
6071 use their normal translation tools like lokalize or poedit to write
6072 the translation. There is even a system in place to handle translated
6075 <li
>The translated .po files are combined with the original docbook
6076 XML document using po4a to create a translated docbook document.
</li
>
6078 <li
>The final step is to use all the generated docbook files and
6079 create PDF and HTML version of the original and translated documents.
</li
>
6083 <p
>This setup work very well, but have a few issues. The biggest
6084 issue is that
<a href=
"http://moinmo.in/DocBook
">the docbook support
6085 we use in moinmoin
</a
> is not actively maintained. The docbook
6086 support is also buggy, and our build system contain workarounds to
6087 make sure the generated docbook is usable despite these bugs.
</p
>
6089 <p
>If you want to have a look at our setup, it is all there in the

6146 <p
>Jeg hørte om det først når jeg jobbet i Redpill Linpro. Men jeg
6147 har også en datter som går på en friskole, som også bruker Skolelinux.
6148 Som kjent har ikke friskoler de samme økonomiske rammebetingelsene som
6149 offentlige skoler, så for dem var det det absolutt beste alternativet.
6150 De anser også Skolelinux som et stabilt system, som bare går og går (i
6151 motsetning til det lille Windows-baserte nettverket de har på
6152 admin-siden).

6156 <p
>Sentralisert drift av tynne og diskløse arbeidsstasjoner. Således
6157 lydløse og raskere arbeidsstasjoner som er bedre i klasserommet.
6158 Lengre levetid på PC
'er. Store besparelser på maskinvare og drift. Og
6159 så klart fjerning av alle lisenskostnader. Personlig synes jeg også at
6160 mange av programmene er bedre enn alternativene. Men dette er ofte en
6161 smakssak og avhengig om man må ha det man er vant til fra før.

6163 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong

6165 <p
>For lite kjentskap til løsningen. Noen ganger for dårlig
6166 kompatibilitet med arbeidsstasjoners/bærbare maskiner sine
6167 nettverksdrivere eller skjermkort. Men dette løser vi i skolene ved
6168 standardisering. Ellers er det få, om nesten ingen, av de kjente
6169 maskinvare / infrastruktur leverandørene til fylkes- / kommuner som
6170 tilbyr denne plattformen. Skal dette endre seg så må kommunene selv
6171 sette slike krav til leverandørene.
</p

6173 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
6175 <p
>Har brukt OpenOffice.org siden starten (
2001 ?), Kun Linux på
6176 desktop siden
2005. Bruker i dag Kubuntu, Libreoffice og ymse annet
6177 programvare til ulik kontorbruk som er lett å installere / teste via
6178 alle programarkivene som finnes.
</p

6180 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
6181 skoler til å ta i bruk fri programvare?
</strong
></p
>
6183 <p
>Fortsette å presentere flere av de gode eksemplene hvor Debian Edu
6184 / Skolelinux brukes i kommuner og enkeltskoler. Vi må få bedre frem
6185 at det er mulig tilknytte både Windows og Mac klienter på denne
6186 plattformen (selv om det vil øke driftskostnadene). Dette gjøres
6187 mange steder. Spesielt er det mange lærere som ønsker å bruke
6188 Windows/Mac-bærbare, gjerne som sin private PC også. Det er også mulig
6189 for kommunen å integrere med Active Directory i stedet for OpenLDAP
6190 som kommer med ut av boksen (selv om også dette øker kostnadene).
6191 Dette vil muligens bidra til å fjerne noe motstand hos noen
6192 potensielle brukere / driftpersonell for å ta i bruk noe
6193 nytt. Fremveksten av mobile brukere og nettbrett går i vår favør.
6194 Brukerne blir kjent og vant til flere nye operativsystemer /
6195 brukergrensesnitt. Så utviklerfellesskapet bør jobbe videre med å
6196 integrere flere nye klienttyper, som ultra lav-kostklienter og
6197 nettbrett (blant annet fri programvare-alternativet

>Inspired by
<a href=
"http://raphaelhertzog.com/tag/interview/
">the
6229 interview series
</a
> conducted by Raphael, I started a Norwegian
6230 interview series with people involved in the Debian Edu / Skolelinux
6231 community. This was so popular that I believe it is time to move to a
6232 more international audience.
</p
>
6234 <p
>While
<a href=
"http://www.skolelinux.org/
">Debian Edu and
6235 Skolelinux
</a
> originated in France and Norway, and have most users in
6236 Europe, there are users all around the globe. One of those far away
6237 from me is Nigel Barker, a long time Debian Edu system administrator
6238 and contributor. It is thanks to him that Debian Edu is adjusted to
6239 work out of the box in Japan. I got him to answer a few questions,
6240 and am happy to share the response with you. :)
6243 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
6245 <p
>My name is Nigel Barker, and I am British. I am married to Yumiko,
6246 and we have three lovely children, aged
15,
14 and
4(!) I am the IT
6247 Coordinator at Hiroshima International School, Japan. I am also a
6248 teacher, and in fact I spend most of my day teaching Mathematics,
6249 Science, IT, and Chemistry. I was originally a Chemistry teacher, but
6250 I have always had an interest in computers. Another teacher teaches
6251 primary school IT, but apart from that I am the only computer person,
6252 so that means I am the network manager, technician and webmaster,
6253 also, and I help people with their computer problems. I teach python
6254 to beginners in an after-school club. I am way too busy, so I really
6255 appreciate the simplicity of Skolelinux.
</p
>
6257 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
6258 project?
</strong
></p
>
6260 <p
>In around
2004 or
5 I discovered the ltsp project, and set up a
6261 server in the IT lab. I wanted some way to connect it to our central
6262 samba server, which I was also quite poor at configuring. I discovered
6263 Edubuntu when it came out, but it didn
't really improve my setup. I
6264 did various desperate searches for things like
"school Linux server
"
6265 and ended up in a document called
"Drift
" something or other. Reading
6266 there it became clear that Skolelinux was going to solve all my
6267 problems in one go. I was very excited, but apprehensive, because my
6268 previous attempts to install Debian had ended in failure (I used
6269 Mandrake for everything - ltsp, samba, apache, mail, ns...). I
6270 downloaded a beta version, had some problems, so subscribed to the
6271 Debian Edu list for help. I have remained subscribed ever since, and
6272 my school has run a Skolelinux network since Sarge.
</p

6274 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
6275 Edu?
</strong
></p
>
6277 <p
>For me the integrated setup. This is not just the server, or the
6278 workstation, or the ltsp. Its all of them, and its all configured
6279 ready to go. I read somewhere in the early documentation that it is
6280 designed to be setup and managed by the Maths or Science teacher, who
6281 doesn
't necessarily know much about computers, in a small Norwegian
6282 school. That describes me perfectly if you replace Norway with
6285 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
6286 Edu?
</strong
></p
>
6288 <p
>The desktop is fairly plain. If you compare it with Edubuntu, who
6289 have fun themes for children, or with distributions such as Mint, who
6290 make the desktop beautiful. They create a good impression on people
6291 who don
't need to understand how to use any of it, but who might be
6292 important to the school. School administrators or directors, for
6293 instance, or parents. Even kids. Debian itself usually has ugly
6294 default theme settings. It was my dream a few years back that some
6295 kind of integration would allow Edubuntu to do the desktop stuff and
6296 Debian Edu the servers, but now I realise how impossible that is. A
6297 second disadvantage is that if something goes wrong, or you need to
6298 customise something, then suddenly the level of expertise required
6299 multiplies. For example, backup wasn
't working properly in Lenny. It
6300 took me ages to learn how to set up my own server to do rsync backups.
6301 I am afraid of anything to do with ldap, but perhaps Gosa will
6304 <p
><strong
>Which free software do you use daily?
</strong
></p
>
6306 <p
>Nowadays I only use Debian on my personal computers. I have one for
6307 studio work (I play guitar and write songs), running AV Linux
6308 (customised Debian) a netbook running Squeeze, and a bigger laptop
6309 still running Skolelinux Lenny workstation. I have a Tjener in my
6310 house, that
's very useful for the family photos and music. At school
6311 the students only use Skolelinux. (Some teachers and the office still
6312 have windows). So that means we only use free software all day every
6313 day. Open office, The GIMP, Firefox/Iceweasel, VLC and Audacity are
6314 installed on every computer in school, irrespective of OS. We also
6315 have Koha on Debian for the library, and Apache, Moodle, b2evolution
6316 and Etomite on Debian for the www. The firewall is Untangle.
</p
>
6318 <p
><strong
>Which strategy do you believe is the right one to use to
6319 get schools to use free software?
</strong
></p
>
6321 <p
>Current trends are in our favour. Open source is big in industry,
6322 and ordinary people have heard of it. The spread of Android and the
6323 popularity of Apple have helped to weaken the impression that you have
6324 to have Microsoft on everything. People complain to me much less about
6325 file formats and Word than they did
5 years ago. The Edu aspect is
6326 also a selling point. This is all customised for schools. Where is the
6327 Windows-edu, or the Mac-edu? But of course the main attraction is
6328 budget.The trick is to convince people that the quality is not
6329 compromised when you stop paying and use free software instead. That
6330 is one reason why I say the desktop experience is a weakness. People
6331 are not impressed when their USB drive doesn
't work, or their browser
6332 doesn
't play flash, for example.

>Many years ago, the
<a href=
"http://www.skolelinux.org/
">Skolelinux
6379 / Debian Edu project
</a
> initiated a student project to create a tool
6380 for making stop motion movies. The proposal came from a teacher
6381 needing such tool on Skolelinux. The project, called
"stopmotion
",
6382 was manned by two extraordinary students and won a school award and a
6383 national aware with this great project. The project was initiated and
6384 mentored by Herman Robak, and manned by the students Bjørn Erik Nilsen
6385 and Fredrik Berg Kjølstad. They got in touch with people at Aardman
6386 Animation studio and received feedback on how professionals would like
6387 such stopmotion tool to work, and the end result was and is used by
6388 animators around the globe. But as is usual after studying, both got
6389 jobs and went elsewhere, and did not have time to properly tend to the
6390 project, and it has been lingering for a few years now. Until last
6393 <p
>Last year some of the users got together with Herman, and moved the
6394 project to Sourceforge and in effect restarted the project under a new
6396 <a href=
"http://sourceforge.net/projects/linuxstopmotion/
">linuxstopmotion
</a
>.
6397 The name change was done to make it possible to find the project using
6398 Internet search engines (try to search for
'stopmotion
' to see what I
6399 mean). I
've been following
6400 <a href=
"https://lists.sourceforge.net/lists/listinfo/linuxstopmotion-community
">the
6401 mailing list
</a
> and the improvement already in place and planned for
6402 the future is encouraging. If you want to make stop motion movies.

>Knut Yrvin her. Jobber i Nokia med å fremme rammeverket Qt og QML
6480 med tilhørende utviklerverktøy. Rollen er som leder av
6481 friprog-samfunn. I fjor var jeg med å legge om utviklingen av Qt til
6482 åpen forvaltning. På den måten kan alle som bidrar til Qt gjøre det
6483 på like vilkår. Nå er det

">over
6485 1000 utviklere
</a
> som bidrar til Qt. Med overgangen til åpen
6486 forvaltning er utviklingen av Qt mer åpen enn Linux-kjernen.
</p
>
6488 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
6490 <p
>Jeg var en av initiativtagerne til Skolelinux i
2001. Skolene slet
6491 med både utstyr og Internett-tilgang. De klarte ikke å møte
6492 forventningene til data i skolen. Driften av PC-ene var uholdbar. Som
6493 regel hadde rektor pekt ut en ivrig lærer til å passe på PC-ene,
6494 gjerne naturfaglæreren. Mange lærere jobbet mye ubetalt overtid for å
6495 vedlikeholde
30-
40 datamaskiner på hver sin skole. Med
300 elever og
6496 lærere som brukere, blir det fort mye mer arbeid enn de
4-
8 timene de
6497 kunne bruke på PC-drift. Skolene hadde kun en femtedel av
6498 IT-budsjettet som ble brukt på PC-ene i rådhuset.
</p
>
6500 <p
>Vi erfarte at skolene hadde mye datautstyr som stod ubrukt. Skolene
6501 manglet penger til Microsoft-lisenser. Selv med solide skolerabatter,
6502 kostet Microsoft-lisensene gjerne like mye som PC-ene i seg selv over
6503 en periode på
5-
6 år.
</p
>
6505 <p
>Viktigheten av språklig mangfold og pedagogiske programmer var også
6506 viktig for oss. Vi oversatte mange skoleaktuelle programmer til
6507 nynorsk, nordsamisk og bokmål. Dette lenge før andre tok denne
6508 oppgaven seriøst. Allerede etter ett år hadde vi etablert et helt
6509 arsenal av skoleaktuelle programmer på nynorsk, bokmål og
6510 nordsamisk. Vi spredde vår ide om språklig mangfold til de andre frie
6511 prosjekter internasjonalt. Resultatene ser vi i mange land. Det er de
6512 frie programmene som kommer på brukernes morsmål. Det er en av flere
6513 gode grunner til at fri programvare som LibreOffice, VLC, KDE og
6514 Firefox konkurrerer ut godseid programvare mange steder i verden.
</p
>
6516 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6518 <p
>Fordelene er at Skolelinux tilbyr over
100 skoleaktuelle programmer
6519 på de norske språkene, uten ett øre i lisenskostnader. Systemet gir
6520 enormt lave driftskostnader med diskløse arbeidsstasjoner og bærbare
6521 med roaming. Skolelinux krever også mindre av maskinvaren.
</p
>
6523 <p
>Man kan fint kjøre systemet med
512 MB RAM på en bærbar PC sammen
6524 med en nettvideo i nettleseren og en presentasjon med
6525 LibreOffice. Konkurrerende system krever fort
2 GB RAM for å få til
6526 noe tilsvarende uten at det går ufattelig tregt. Skal man gjøre noe
6527 nyttig, krever konkurrentene til Linux mye større harddisk. Skoler har
6528 rapportert at de fort har fått
50% flere nye maskiner om de velger
6529 Linux. Dette i tillegg til de årlige besparelsene ved å unngå
6530 lisensbetaling til godseid programvare.
</p
>
6532 <p
>De lave driftskostnadene gjør at delstater i Europa har titusener
6533 av datamaskiner med Skolelinux i skolen. F.eks. er det under ti
6534 personer som drifter
70.000 PC-systemer i skolene i Extremadura i
6535 Spania. Det er slett ikke uvanlig at norske kommuner har
1500-
2000
6536 datamaskiner med Skolelinux. Driften tar ett årsverk. Slår flere
6537 kommuner seg sammen, kan de få samme sentraliserte stordriftsfordeler
6538 som delstater i Tyskland og Spania. Delstater som kjører Skolelinux
6539 på alle skolene. Bare noen få personer sentraldrifter titusenvis av
6542 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6544 <p
>Den største ulempen for Skolelinux er motstand mot Linux fra
6545 IT-sjefer i det offentlige. Dette er ledere som holder innlegg som
6546 snytt ut av evangelist-håndboka til Microsoft. Dette gjøres i ett
6547 arbeidsmarked med stor vekst i etterspørselen etter Linux-fagfolk i
6548 privat sektor. Etterspørselen har økt mer enn noe annet tekniske yrke
6549 siste tiåret. Åtte av ti ledere vil ansette Linux-fagfolk i
2012,
6550 rapporterer jobbnettstedet Dice.com på oppdrag av Linux
6551 Foundation.
</p
>
6553 <p
>Det mangler
16.000 ingeniører og IKT-fagfolk i Norge rapporterte
6554 arbeids- og velferdsetaten NAV. Linux-fagfolk kan velge svært
6555 interessante jobber med alt fra apps på ledende mobilsystem laget med
6556 Linux, sky- tjenester eller web-applikasjoner. De raskest voksende
6557 teknologiselskapene i verden er ute etter Linux-fagfolk. Det være seg
6558 Amazon, Google, Facebook og IBM for å nevne noen. Linux er kritisk
6559 for å sikre veksten i markedet. Det sier seg selv at lønningene og
6560 jobbmulighetene er bedre enn for andre tekniske yrker.
</p
>
6562 <p
>Skal man lage apps for mobilen, smart-TV-en eller
6563 underholdningssystemet i bilen eller på flyet, er det Linux som
6564 gjelder. Med en slik konkurranse om Linux-kompetansen, kombinert med
6565 motstanden mot Linux hos mange IT-sjefer i offentlig sektor, så
6566 hindrer kommunene rekruttering av flere Linux- fagfolk. Skolene blir
6567 tvunget til å velge dyrere og mindre komplette IT-system. De har
6568 blitt hengende igjen slik IT var på begynnelsen av
2000- tallet. Dette
6569 fordi IT-ledere ikke har tilpasset seg markedet det siste tiåret.
</p
>
6571 <p
>Når det er sagt, er Skolelinux svært enkelt å lære seg også for de
6572 som ikke kan. Det viser alle lærerne som drifter systemet for
6573 hundrevis og tusenvis av systemer. Det meste er på plass rett ut av
6574 boksen. I tillegg er det solid med dokumentasjon med god hjelp på
6575 nettet. Det er mange kommuner som har ansatt en lærer som først lærte
6576 Skolelinux på sin skole, for så å drifte alle PC-ene i kommunen med
6577 Skolelinux. Det kan fort være snakk om
1000-
3000 datamaskiner på
10-
15
6578 skoler som sentraldriftes med en stilling. Står man ordentlig fast,
6579 kan man også kjøpe profesjonell hjelp fra selskap som støtter
6580 Skolelinux. Det er flere slike selskap i Norge og i utlandet.

>Qt SDK, LibreOffice, Firefox, VLC og KDE-skrivebordet. Dette på et
6585 Debian-basert GNU/Linux-system. Jeg bruker også noen morsomme
6586 3D-spill. Idag kan jeg velge mellom over
30.000 Linux-programmer. Det
6587 finnes ikke tid i livet å undersøke alle valgmulighetene. Derfor er
6588 det bra med Skolelinux i skolen, da utvalget av programmer er
6589 begrenset til hva som er aktuelt i skolefagene.

><strong
>Hvilken strategi tror du er den rette å bruke for å få
6592 skoler til å ta i bruk fri programvare?

6594 <p
>Vi må selge hele Skolelinux forhåndsinstallert på maskinvare i hele
6595 pakker med
50-
100-
1000 PC-klienter med servere. Dette kan selges til
6596 enkeltskoler eller hele kommuner. Pakken må inneholde tjenermaskiner,
6597 svært rimelige diskløse arbeidsstasjoner, nettbrett med Plasma Active,
6598 og bærbare med roaming. Alt er godt testet med Debian. I et slikt
6599 anbud er det mulig å legge til sentraliserte drifts- og
6600 støttetjenester.
</p
>
6602 <p
>Man bør også selge sky-tjenester som læreadministrative systemet
6603 Moodle og driftsovervåking. I tillegg så bør man slenge seg på med
6604 presentasjoner de gangene LibreOffice og andre friprog-produkter
6605 selges til kommuner.

6681 mulig å involvere utdanningssektoren direkte i arbeidet, for eksempel
6682 gjennom studentprosjekter der elevene selv er med å utforme
6683 programvare direkte eller indirekte gjennom aktive bidrag. Dette gjør
6684 ikke bare samarbeidet tettere, men fokuset på standarder og friheten
6685 til å velge sin egen løsning vil kanskje stimulere interessen for
6686 framtidig deltakelse i bransjen. Vi som driver med fri og åpen

6740 library. I hope someone find a solution to that problem before Wheezy
6741 is frozen. An alternative would be for us to rewrite wpad-extract to
6742 use some other javascript library currently working in Wheezy, but no
6743 known alternative is known at the moment.

>This automatic proxy system allow the roaming workstation (aka
6746 laptop) setup in Debian Edu/Squeeze to use the proxy when the laptop
6747 is connected to the backbone network in a Debian Edu setup, and to
6748 automatically use any proxy present and announced using the WPAD
6749 feature when it is connected to other networks. And if no proxy is
6750 announced, direct connections will be used instead.

6752 <p
>Silently using a proxy announced on the network might be a privacy
6753 or security problem. But those controlling DHCP and DNS on a network
6754 could just as easily set up a transparent proxy, and force all HTTP
6755 and FTP connections to use a proxy anyway, so I consider that
6756 distinction to be academic. If you are afraid of using the wrong
6757 proxy, you should avoid connecting to the network in question in the
6758 first place. In Debian Edu, the proxy setup is updated using dhcp and
6759 ifupdown hooks, to make sure the configuration is updated every time
6760 the network setup changes.

6787 være med som oversetter. Jeg kom med på en utviklersamling og
6788 prosjektet var da helt i starten. Det var spennende å være med mens
6789 prosjektet vokste til og utviklet seg.
</p

6791 <p
>Jeg har «alltid» vært språkinteressert og hadde nettopp startet med
6792 Linux og tror jeg tenkte det passet å bidra. Var også glad for å få
6793 en Debian-distribusjon, og ville gjerne bruke den selv. Til å begynne
6794 med brukte jeg først Mandrake og så Debian. Og siden jeg oppdaget at
6795 det ikke var noen mulighet for å bruke den som enkeltstående i lang
6796 tid, så gikk jeg etterhvert over til Kubuntu

6800 <p
>Løsningen er forholdsvis lett å sette opp, gratis, fri programvare
6801 og gjør det mulig å gjenbruke eldre maskiner. Det fine med Debian er
6802 at det er stabilt og har en veldig stor mengde programmer. Jeg liker
6803 også apt. :-) Jeg liker også friheten ved Linux og muligheten til å
6804 delta og forme sin egen datahverdag.

6808 <p
>Skolelinux er for lite kjent og for sent ute med å gi ut nye
6809 versjoner.
</p
>
6811 <p
>Da jeg selv i hovedsak bruker Kubuntu, så kan jeg egentlig ikke
6812 svare så detaljert rundt ulempene med Skolelinux. Hovedårsaken til at
6813 jeg bruker Kubuntu er nok at da vi begynte med det mener jeg det ikke
6814 var noen annen løsning. «Vandrende arbeidsstasjon» mener jeg ikke
6815 fantes da. Dessuten ville jeg ha siste versjon, da den KDE-versjonen
6816 som var i Skolelinux den gangen var en god del enklere (tror det var
6817 KDE
2) var dårligere i mine øyne enn versjon
3.

6835 <p
>Det viktigste er å forankre beslutningen i kollegiet og med de som
6836 er ansvarlige for å vedlikeholde og bruke datamaskinene. Flest mulig
6837 bør være med på å holde det (sosialt) vedlike, kjenne og støtte
6838 prinsippene. Som enkeltmannsprosjekt blir det lett veldig sårbart,
6839 særlig når (Skole)linux ennå i stor grad er en motkultur og ikke noe
6840 en stor nok andel av beslutningstakere, brukere osv kjenner til og
6843 <p

6844 oppdatert, minimere antall feil, ha en god kontakt med brukerne og
6845 attraktivt og spennende programmer. Beholde alt som er bra og ha det
6846 tilgjengelig samtidig som man tilbyr det nyeste og rareste for de som

>Since the Lenny version of
6857 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>, a
6858 feature to save power have been included. It is as simple as it is
6859 practical: Shut down unused clients at night, and turn them on again
6860 in the morning. This is done using the
6861 <a href=
"http://packages.qa.debian.org/s/shutdown-at-night.html
">shutdown-at-night
</a
> Debian package.
</p
>
6863 <p
>To enable this feature on a client, the machine need to be added to
6864 the netgroup shutdown-at-night-hosts. For Debian Edu, this is done in
6865 LDAP, and once this is in place, the machine in question will check
6866 every hour from
16:
00 until
06:
00 to see if the machine is unused, and
6867 shut it down if it is. If the hardware in question is supported by
6869 <a href=
"http://packages.qa.debian.org/n/nvram-wakeup.html
">nvram-wakeup
</a
>
6870 package, the BIOS is told to turn the machine back on around
07:
00 +-
6871 10 minutes. If this isn
't working, one can configure wake-on-lan to
6872 try to turn on the client. The wake-on-lan option is only documented
6873 and not enabled by default in Debian Edu.
</p
>
6875 <p
>It is important to not turn all machines on at once, as this can
6876 blow a fuse if several computers are connected to the same fuse like
6877 the common setup for a classroom. The nvram-wakeup method only work
6878 for machines with a functioning hardware/BIOS clock. I
've seen old
6879 machines where the BIOS battery were dead and the hardware clock were
6880 starting from
0 (or was it
1990?) every boot. If you have one of
6881 those, you have to turn on the computer manually.
</p
>
6883 <p
>The shutdown-at-night package is completely self contained, and can
6884 also be used outside the Debian Edu environment. For those without a
6885 central LDAP server with netgroups, one can instead touch the file
6886 <tt
>/etc/shutdown-at-night/shutdown-at-night
</tt
> to enable it.
6887 Perhaps you too can use it to save some power?

6906 <p

6907 beta2 (there are more, see announcement for full list):
</p
>
6911 <li
>It is now possible to change the pre-configured IP subnet from
6912 10.0.0.0/
8 to something else by using the subnet-change tool after
6913 the installation.
</li
>
6915 <li
>Too full partitions are now automatically extended on the Main
6916 Server, based on the rules specified in /etc/fsautoresizetab.
</li
>
6918 <li
>The CUPS queues are now automatically flushed every night, and all
6919 disabled queues are restarted every hour. This should cut down on
6920 the amount of manual administration needed for printers.
</li
>
6922 <li
>The set of initial users have been changed. Now a personal user
6923 for the local system administrator is created during installation
6924 instead of the previously created localadmin and super-admin users,
6925 and this user is granted administrative privileges using group
6926 membership. This reduces the number of passwords one need to keep
6927 up to date on the system.
</li
>
6931 <p
>The new main server seem to work so well that I am testing it as my
6932 private DNS/LDAP/Kerberos/PXE/LTSP server at home. I will use it look
6933 for issues we could fix to polish Debian Edu even further before the
6934 final Squeeze release is published.

6936 <p

>With some computer hardware, one need non-free firmware blobs.
6950 This is the sad fact of todays computers. In the next version of
6951 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> based
6952 on Squeeze, we provide several scripts and modifications to make
6953 firmware blobs easier to handle. The common use case I run into is a
6954 laptop with a wireless network card requiring non-free firmware to
6955 work, but there are other use cases as well.
</p
>
6957 <p
>First and foremost, Debian Edu provide ISO images for DVD and CD
6958 with all firmware packages in the Debian sections main and non-free
6959 included, to ensure debian-installer find and can install all of them
6960 during installation. This take care firmware for network devices used
6961 by the installer when installing from from local media. But for
6962 example multimedia devices are not activated in the installer and are
6963 not taken care of by this.
</p
>
6965 <p
>For non-network devices, we provide the script
6966 <tt
>/usr/share/debian-edu-config/tools/auto-addfirmware
</tt
> which
6967 search through the
<tt
>dmesg
</tt
> output for drivers requesting extra
6968 firmware. The firmware file name is looked up in the Contents-ARCH.gz
6969 file available in the package repository, and the packages providing
6970 the requested firmware file(s) is installed. I have proposed to do
6971 something similar in debian-installer (BTS report
6972 <a href=
"http://bugs.debian.org/
655507">#
655507</a
>), to allow PXE
6973 installs of Debian to handle firmware installation better. Run the
6974 script as root from the command line to fetch and install the needed
6975 firmware packages.
</p
>
6977 <p
>Debian Edu provide PXE installation of Debian out of the box, and
6978 because some machines need firmware to get their network cards
6979 working, the installation initrd some times need extra firmware
6980 included to be able to install at all. To fill the PXE installation
6981 initrd with extra firmware, the
6982 <tt
>/usr/share/debian-edu-config/tools/pxe-addfirmware
</tt
> script is
6983 provided. Again, just run it as root on the command line to fill the
6984 PXE initrd with firmware packages.
</p
>
6986 <p
>Last, some LTSP clients might also need firmware to get their
6987 network cards working. For this,
6988 <tt
>/usr/share/debian-edu-config/tools/ltsp-addfirmware
</tt
> is
6989 provided to update the LTSP initrd with firmware blobs. It is used
6990 the same way as the other firmware related tools.
</p
>
6992 <p
>At the moment, we do not run any of these during installation. We
6993 do not know if this is acceptable for the local administrator to use
6994 non-free software, and it is their choice.

6996 <p

7052 <description><p
>The next version of
<a href=
"http://www.skolelinux.org/
">Debian Edu
7053 / Skolelinux
</a
> will include a new tool
7054 <tt
>sitesummary2ldapdhcp
</tt
>, which can be used to quickly set up all
7055 the computers in a school without much manual labour. Here is a short
7056 summary on how to use it to set up a new school.
</p
>
7058 <p
>First, install a combined Main Server and Thin Client Server as the
7059 central server in the network. Next, PXE boot all the client machines
7060 as thin clients and wait
5 minutes after the last client booted to
7061 allow the clients to report their existence to the central server. When
7062 this is done, log on to the central server and run
7063 <tt
>sitesummary2ldapdhcp -a
</tt
> in the
<tt
>konsole
</tt
> to use the
7064 collected information to generate system objects in LDAP. The output
7065 will look similar to this:
</p
>
7067 <p
><blockquote
><pre
>
7068 % sitesummary2ldapdhcp -a

7072 Enter password if you want to activate these changes, and ^c to abort.
7074 Connecting to LDAP as cn=admin,ou=ldap-access,dc=skole,dc=skolelinux,dc=no
7075 enter password: *******
7077 </pre
></blockquote
></p
>
7079 <p
>After providing the LDAP administrative password (the same as the
7080 root password set during installation), the LDAP database will be
7081 populated with system objects for each PXE booted machine with
7082 automatically generated names. The final step to set up the school is
7083 then to log into
<a href=
"https://oss.gonicus.de/labs/gosa/
">GOsa
</a
>,
7084 the web based user, group and system administration system to change
7085 system names, add systems to the correct host groups and finally
7086 enable DHCP and DNS for the systems. All clients that should be used
7087 as diskless workstations should be added to the workstation-hosts
7088 group. After this is done, all computers can be booted again via PXE
7089 and get their assigned names and group based configuration
7090 automatically.
</p
>
7092 <p
>We plan to release beta3 with the updated version of this feature
7093 enabled this weekend. You might want to give it a try.
</p
>
7095 <p
>Update
2012-
01-
28: When calling sitesummary2ldapdhcp to add new
7096 hosts, one need to add the option -a. I forgot to mention this in my
7097 original text, and have added it to the text now.

7106 <description><p
>I serien med intervjuer av folk i
7107 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet, har jeg nå
7108 lyktes med å få tak i en skolemann som ikke er aktiv med utviklingen,
7109 men likevel har vært med nesten siden starten av prosjektet. Jeg
7110 ønsker derfor velkommen til Paul Reidar Løsnesløkken, en mann med
7111 mange års erfaring i bruk av Skolelinux.
</p
>
7113 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
7115 <p
>Jeg driftet tidligere IKT løsningen for skolene i
7116 <a href=
"http://www.nord-odal.kommune.no/
">Nord-Odal
</a
>. I dag er jeg
7117 IKT-konsulent for hele kommunen og samarbeider med
7118 <a href=
"http://www.hedmarken-ikt.no/
">Hedmark-IKT
</a
> for best mulig
7119 tjenester til kommunen. Jeg har bakgrunn som elektronikkreparatør og
7120 grunnskolelærer og har tatt en del fag innen IKT, i hovedsak
7121 driftsfag. IKT i Nord-Odal kommune blir i dag driftet av Hedmark IKT
7122 som er et samarbeid mellom Løten, Stange, Grue, Hamar, Kongsvinger og
7123 Nord-Odal. Jeg er fortsatt
"IKT-personen
" på skolene i kommunen og
7124 følger opp og gjør enkelte mindre endringer der.
</p
>
7126 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
7128 <p
>Kommunen satset på Skolelinux i
2004. Jeg var ikke med i
7129 beslutningsprosessen den gang, men ble likevel med fra starten når
7130 dette ble levert.
</p
>
7132 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7134 <p
>Fordelene med Skolelinux er rask oppstart, sentral drift av
7135 klientene, klienter som jobber raskt og effektivt, bedre
7136 funksjonalitet på eldre utstyr og en ganske god programpakke med fri
7137 programvare som følger med. Løsningen med halvtykke klienter gjør at
7138 prosessering skjer lokalt med alltid ferske maskiner.
</p
>
7140 <p
>Skolelinux kan fungere godt på gammelt utstyr, men det er klart at
7141 utstyr også blir for gammelt selv for Skolelinux. I forbindelese med
7142 at vi nylig fikk nye servere og ny installasjon kastet jeg ut ca
60
7143 klienter som fortsatt var i drift etter at de var kjøpt godt brukt i
7144 2004. Noe var rundt
15 år gammelt, men var fortsatt i bruk. Noen
7145 klaget på at det nå gikk veldig tregt på en del pedagogiske nettsider
7146 med flash o.l. Det er fullt forståelig.
</p
>
7148 <p
>Jeg fikk nylig et spørsmål fra ungdomsskolens rektor om jeg kunne
7149 legge inn
<a href=
"http://freemind.sourceforge.net/
">FreeMind
</a
>, et
7150 tankekartprogram , på skolens elev-Windowsmaskiner. Lærerne hadde
7151 vært på kurs og ville ta dette i bruk. Skolen har ca halvparten av
7152 elevmaskinene på bærbare Windowsmaskiner. Da kunne jeg fortelle at
7153 dette programmet allerede lå inne på den nye Skolelinuxløsningen
7154 som nettopp var satt i drift, klart til bruk.
</p
>
7156 <p
>Vi har de bærbare maskinene på ungdomsskolen i domene med
7157 Skolelinux. Dette fungerer også meget bra nå. Elevene får opp en
7158 midlertidig windowsprofil når de logger på. Denne profilen slettes
7159 etter at de logger av, noe som medfører rene profiler hver gang de
7160 starter opp en maskin. De må lagre i sin Skolelinprofil, noe som
7161 medfører at de får tak i sine filer uavhengig av om de starter en
7162 Windowsmaskin eller en Skolelinuxklient. Det er mye mindre trafikk i
7163 det trådløse nettet etter at ikke hele profiler blir lastet opp til de
7164 enkelte Windowsmaskinene og tilbake når man avslutter. Jeg vet ikke om
7165 dette er standardoppsett i Skolelinux, men slik er vårt oppsett
7168 <p
>Vi har i flere år satt opp vår løsning slik at skriverkøer slettes
7169 og skrivere startes hver natt. Hyggelig å høre at dette nå skal bli
7170 en standard i Skolelinuxløsningen. Dette har vært en god hjelp for
7173 <p
>Elevene er lite opptatt av om de jobber på en Skolelinux eller en
7174 Windowsmaskin bare de har de programmene de trenger og at det virker
7175 når det skal brukes. Vi kjører mest mulig de samme programmene på
7176 Windows som i Skolelinux, som f.eks Audacity og LibreOffice.
</p
>
7178 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7180 <p
>Lærere bruker hos oss Windows. Dette fordi de da selv har mer
7181 kontroll over sin maskin, kan bruke den overalt, og kan legge inn
7182 programmer selv når de trenger noe i forhold til kurs o.l de er
7183 på. Jeg tror lærernes selvstendighet her gjør dem tryggere på IKT-bruk
7184 generelt. Det at de av og til får opp advarsler og lignende gjør også
7185 at de må tenke igjennom og spørre om ting rundt datasikkerhet.
</p
>
7187 <p
>Det er en del programmer vi bruker som ikke finnes for Linux. Mest
7188 brukt er nok Photostory3 som brukes i mange sammenhenger, særlig på
7189 ungdomsskolen, bl.a. til å lage herbarier (plantesamling) . Dette
7190 finnes gratis for Windows, men er ikke fri programvare. Vi er opptatt
7191 av at programmer elevene bruker på skolen også kan brukes gratis
7192 hjemme. Det er også en del programmer som brukes til spesielle elever
7193 som bare går i Windows. Det er viktig med fokus på funksjoner og ikke
7194 på hvilket OS man bruker.
</p
>
7196 <p
>For oss er det kombinasjonen mellom Skolelinux og Windows som gir
7197 oss en god og hel løsning. Skolelinux er best der de er gode.
</p
>
7199 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
7201 <p
>Selv er det LibreOffice jeg bruker til daglig. Jeg bruker selv en
7202 Windowsmaskin. Jeg har benyttet en del fri programvare i forbindelse
7203 med sjekking av trafikk i nettverk, slik som Wireshark, men dette er
7204 jo ikke aktuelt for skolene. Jeg er generelt glad i programmer som
7205 fungerer på både Linux og Windows og gjerne MAC.
</p
>
7207 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
7208 skoler til å ta i bruk fri programvare?
</strong
></p
>
7210 <p
>Det er viktig at det benyttes programmer som elevene også kan ta i
7211 bruk hjemme. Det skal da være enkelt, lovlig og gratis for
7212 elevene. Da er jeg ikke lenger veldig opptatt av om det kalles
"fri
7213 programvare
". For skolene tror jeg
"gratis
" og
"funksjonelt
" er bedre
7214 begreper enn
"fri
" i forhold til programmer. De fleste skiller nok
7215 ikke mellom
"fri
" og
"gratis
". Det er nå svært mange elever som
7216 benytter OpenOffice eller LibreOffice som sin primære kontorpakke

7232 are shown the same page as a welcome page when they log in for the

7235 <p

7244 <p

>During christmas, I have been working getting the next version of
7273 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> ready
7274 for release. The initial problem I looked at was particularly
7275 interesting.
</p
>
7277 <P
>The installer would hang at the end when it was doing it
7278 post-installation configuration, and whatevery I did to try to find
7279 the cause and fix it always worked while I tested it, but never when I
7280 integrated it into the installer and ran the installation from
7281 scratch. I would try to restart processes, close file descriptors,
7282 remove or create files, and the installer would always unblock and
7283 wrap up its tasks.
</p
>
7285 <p
>Eventually the cause was found. The kernel was simply running out
7286 of entropy, causing the Kerberos setup to hang waiting for more.
7287 Pressing keys was adding entropy to the kernel, and thus all my tries
7288 to fix the problem worked not because what I was typing to fix it, but
7289 because I was typing.
</P
>
7291 <p
>The fix I implemented was to add a background process looking at
7292 the level of entropy in the kernel (by checking
7293 /proc/sys/kernel/random/entropy_avail), and if it was too small, the
7294 installer will flush the kernel file buffers and do
'find /
' to
7295 generate some disk IO. Disk IO generate entropy in the kernel, and is
7296 one of the few things that can be initated from within the system to
7297 generate entropy.

7316 Denne gangen har jeg besøk av et avtroppende styremedlem i
7317 <a href=

</strong

7322 <p
>Jeg heter Peter Hansteen, og jobber til daglig som seniorkonsulent
7323 i EDB ErgoGroup i Bergen. I praksis betyr det systemadministrasjon på
7324 Unix (primært Solaris, men en viss komponent av Linux). Men Solaris
7325 er for meg et relativt nytt bekjentskap, hovedplattformen min har
7326 generelt vært OpenBSD og til dels FreeBSD.
</p
>
7328 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
7330 <p
>Jeg husker ikke helt alle detaljene mer ;) - men jeg tror det var
7331 gjennom news-gruppen no.it.os.unix.linux.diverse, efn-listen og
7332 etterhvert også BLUG-miljøet her i Bergen. Vi hadde et par
7333 Skolelinux-sentrerte BLUG-møter for noen år siden, og det har vært et
7334 par Skolelinux-utviklersamlinger her.

7336 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong

7338 <p
>Jeg bruker dessverre ikke Skolelinux daglig. Men slik jeg kjenner
7339 prosjektet har det vært i stand til å ta opp i seg det beste av fri
7340 programvare i mange kategorier, så fra et sysadmin-perspektiv ser det
7341 ut som en svært behagelig sak. For brukerne er det vel både en fordel
7342 og en ulempe at det ikke er Windows. Men vi håper at fordelene med et
7343 fritt system etterhvert vil bli åpenbare for både elever, lærekrefter
7344 og foreldre.

7346 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7348 <p
>Vel, ulempen er vel først og fremst at andre aktører med mer
7349 kapitalmuskel har klart å etablere seg som det både lærere og foreldre
7350 føler seg trygge på, selv om det etter mitt hode ikke er noen grunn
7351 til å være spesielt trygg på de kommersielle alternativene.
</p

7353 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
7355 <p
>Når jeg får bestemme helt selv, bruker jeg kun fri programvare. Da
7356 helst med vekt på ting som kjører greit på OpenBSD. Hjemme er det
7357 OpenBSD, Ubuntu eller FreeBSD vi bruker. På skrivebordet er det en
7358 avveining mellom Gnome, KDE eller hva-det-nå-heter som er
7359 standardvalget i Ubuntu, ellers er det de kjente tingene som
7360 LibreOffice, Emacs, mplayer. På server er det selvfølgelig Apache,
7361 for overvåking både OpenNMS og Nagios (det bare ble sånn, og
7362 forskjellige siter). Jeg skriver til tider om slikt jeg holder på med
7364 <a href=

7366 <p
>Men vi må nevne at selv vi har en Microsoft-ting som vi slår på når
7367 vi av en eller annen grunn må. Det betyr igjen vanligvis når en
7368 mobiltelefon eller en annen lukket elektronisk dings krever kontakt
7369 via en slik for å få oppdateringene sine.

7377 <p

7378 sentral sak er å fokusere på fri programvare og åpne standarder som de

7380 mye i bakgrunnen i forhold til strevet etter å lage det mest mulig
7381 'brukervennlige
' systemet. Det er en tung vei å gå, så det er
7382 forståelig at freenix-aktivister heller velger å skrive kode og annet
7383 som er mer lystbetont. Mer praktisk tror jeg vi må gjøre i alle fall
7384 to ting: For det første sørge for å fortsette med å levere det best
7385 mulige frie produktet, slik at det er lett å både komme i gang og
7386 holde systemene i daglig drift, og for det andre
2) spore opp mulige
7387 aktivister der de finnes, via lokale brukergrupper, sosiale medier
7388 eller annet og sørge for at de fortsetter å være aktive. Mer og
7389 mindre uformelle treff kan være nyttig i tillegg til de mer
7390 organiserte møtene med foredrag, konferanser og utviklersamlinger.

</strong
></p
>
7407 <p
>Mitt navn er Frode Jemtland, og jeg jobber i Hedmark IKT, som er et
7408 driftsselskap for Grue, Hamar, Kongsvinger, Løten, Nord-Odal og Stange
7409 kommuner. Her er jeg leder for avdelingen Løsninger og Arkitektur. Vi
7410 har i hovedansvar for servere, infrastruktur og løsninger som
7413 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
7415 <p
>Jobbet i IBM fra
2000, og da spesielt med Linux. Dette var da et av
7416 de mest tydelige linux prosjektene i Norge, og her ønsket jeg å
7417 bidra. Var aktivt med i prosjektet i
4-
5 år.
</p
>
7419 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7421 <p
>Fordelene slik jeg ser det er den sentraliserte driftmodellen, og
7422 alle de vel gjennomtenkte løsningene som er inkludert i denne
7423 løsningen. Samtidig er det basert på en stabil, og godt kjent
7424 plattform. Dette vil si at man har en løsning som skal være mye
7425 tilgjengelig, og hvor det er relativt enkelt å få tak i personer som
7426 kan mye om den grunnleggende plattformen.
</p
>
7428 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7430 <p
>De største utfordringene med en løsningen er at den er intensiv på f.eks
7431 nettverk. I seg selv ikke et problem for en enkelt skole, men skal løsningen
7432 kjøres i større skala, med sentraliserte servere, så gir dette noen
7433 utfordringer.
</p
>
7435 <p
>Utifra hva jeg har sett på større installasjoner så er det ikke så
7436 enkelt å skjønne, hva som bør gjøres for at den skal skaleres opp, og
7437 da ta godt vare på alle sider av dette, ikke bare mer server å fordele
7438 last/trykk, men hvordan også beholde robustheten og fleksibiliteten i
7439 løsningen.
</p
>
7441 <p
>En annen utfordring er at stadig flere produkter som skal brukes i
7442 skoleløsningen ikke er laget til å kunne brukes i en
7443 skolelinuxløsning. Det blir derfor fort mye skreddersøm i de
7444 forskjellige installasjonene, for å få diverse pedagogiske programmer,
7445 webløsninger, smartboards, m.m. til å fungere. Man er også en for
7446 liten kundebase til at leverandørene ønsker å gjøre noe med
7447 utfordringen. Problemet overlates til oss.
</p
>
7449 <p
>Det er også en kontinuerlig utfordring rundt problemet med å holde
7450 programvare på stabile versjoner, kontra å få ny funksjonalitet. Dette
7451 er jo en konflikt mellom oss som ønsker å drifte en stabil, og
7452 kostnadseffektiv løsning, mot sluttbrukerne som ønsker seg funksjoner
7453 det er vant med fra andre løsninger, eller som de må ha for at et
7454 eller annet nytt produkt skal fungere i løsningen. Dette er en
7455 utfordring også for andre plattformer.
</p
>
7457 <p
>En siste utfordring som ikke har noe med løsningen å gjøre, men med
7458 det omkringliggende miljøet denne skal kjøre i, er at de enhetene som
7459 skal drifte dataløsninger for kommuner og fylkeskommuner begynner å
7460 profesjonaliseres, og er da avhengig av å ha standard løsninger for å
7461 drifte store brukermasser. MS er selvsagt klar over dette, og har jo
7462 nå flere områder de begynner å bli veldig dominerende på. Den største,
7463 og mest problematiske er katalogtjenesten. Man får snart ikke tak i
7464 større løsninger som ikke krever en AD. Når man da har store enheter
7465 som drifter både kommunalt ansatte og skoler, så vil det være et
7466 stordriftargument å standardisere på en katalog tjeneste, og da har
7467 man ikke noe valg. Her er alle slike driftsenheter for små til å få
7468 gjort om på dette. Her burde konkurransemyndighetene kommet på
7469 banen. Men konkurransetilsynet i USA griper sjeldent (og ikke før det
7470 har gått veldig lang tid) inn i monopolsituasjoner så lenge
7471 monopolisten er et amerikansk firma, så da har vel ikke andre
7472 myndigheter så mye de skulle ha sagt....
</p
>
7474 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
7476 <p
>Privat kjører jeg Debian på alle mine datamaskiner. Det gjør jeg
7477 også på min jobbmaskin. Vi har også
15-
20 linux servere av typene
7478 SuSE, Debian, Redhat, CentOS m.m. Jeg bruker derfor mye fri
7479 programvare. Av enkelt programmer kan sikkert masse nevnes. Hvis vi
7480 skal begrense oss til daglig, så må jeg si: OpenOffice, Firefox,
7481 Kontact, Kopete, Amarok,
7482 <a href=
"http://gramps-project.org/
">Gramps
</a
>, Kate, ssh, bash,
7483 rsync, backuppc m.m.
</p
>
7485 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
7486 skoler til å ta i bruk fri programvare?
</strong
></p
>
7488 <p
>Det er et godt spørsmål, som jeg har lurt på selv.
</p
>
7490 <p
>Argumentene som ofte har vært brukt om at ting koster mindre holder
7491 ikke mål når man ser på hva som faktisk koster penger. Det er de
7492 ansatte som er en kostnadsdriver. Det vil si at hvis man har et system
7493 som den ansatte kan, så vil en kostnad på dette systemet kunne
7494 forsvares ganske mye ved at den ansatte gjør dette raskere og
7495 effektivt. Også uten å måtte eventuelt leie inn folk.
</p
>
7497 <p
>Jeg syns det er viktigere å fokusere på prinsippet med å velge fri
7498 programvare, men det er også et felt hvor man fort møter lite
7499 forståelse blant de ansatte i skolen.
</p
>
7501 <p
>Her må nok strategien fortsette å være at de sentrale myndighetene
7502 må sende tydelige signaler for hva de ønsker at offentlige enheter
7503 skal gjøre. Det var mye positivt på gang ang. dette for et par år
7504 siden. Både med eNorge og eKommune planene, men dette syns jeg har
7505 stoppet opp. En del av dette kan jo kanskje være usikkerheten som
7506 etter hvert har blitt, når man har sett kompleksiteten i de
7507 prosjektene som har blitt igangsatt. Det har også blitt noe usikkerhet
7508 i markedet ref. Sun, Oracle, Novell, Microsoft m.m. Samtidig har jo
7509 også de proprietære programleverandørene sørget for å endre sine
7510 lisenser slik at man uansett ikke slipper unna kostnaden til deres
7511 produkter, selv om man skulle velge alternativer. Da er det økonomiske
7512 argumentet, som jeg nevnte tidligere, spilt ganske godt ut over
7513 sidelinjen.

7537 hadde vel hørt om prosjektet i media før en gjeng i Trondheim startet
7538 opp SPIST, Skolelinux-prosjektet i Sør-Trøndelag, hvor vi hjalp noen
7539 skoler i nærområdet med å installere Skolelinux og finne brukt
7540 IT-utstyr til disse. Det var moro å gjøre noe praktisk for å spre
7541 Skolelinux, og å se hvor fort gjort det var å sette opp utrangerte
7542 klientmaskiner og få disse opp som tynnklienter på helt nye datasaler
7543 på skolene, kun med kostnaden til servere.

7545 <p

7547 <p
>Det er et system spesielt skreddersydd for drift av et stort antall

7549 er enkelt og billig å installere og drifte, og det trenger ikke ny
7550 maskinvare for god ytelse.

7555 installerbart rett ut av boksen. Distribusjonen har til tider hatt
7556 litt gammel programvare pga. at den følger Debian sine utgivelser.
7557 Kanskje man skulle vurdert en versjon basert på Ubuntu eller andre
7558 distribusjoner i tillegg?

7566 OI Shopping list, Shuffle, ZXing, OI Notepad og ADW Desktop. På jobb

>En bør fokusere på totalkostnader inkludert driftsbehov,
7574 fleksibilitet, åpenhet og ikke låsing til en leverandør framfor sparte
7575 lisenskostnader, samt programvarens kvalitet og fortrinn, og at den
7576 fritt kan brukes på et ubegrenset antall PC-er, også hjemme hos
7577 elevene. En bør også forbedre den fri programvaren ved testing,
7578 bugrapportering og kodebidrag om man kan, og ikke anbefale programvare
7579 uten at man har forsikret seg at den har tilstrekkelig kvalitet,
7580 ellers kan man lett oppnå det motsatte. Tror en bør selge inn
7581 konseptet til fylkes-/statsnivå, kanskje med bidrag til
7582 utviklingsarbeid fra disse som alle landets skoler kan få glede

>Mine bloggposter om Linux i skolene i Norge førte til at inspektør
7593 og ildsjel på Harestad skole tok kontakt og fortalte at de bruker
7594 Linux på sin skole, og lurte på om de kunne bidra til å gjøre
7595 fordelene kjent. Riktig nok bruker de ikke
7596 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
> på denne skolen,
7597 men jeg synes dette er en god anledning til å gjøre flere fasetter
7598 rundt Linux-økosystemet kjent, og tok et lite intervju.

7602 <p
>Mitt navn er Odin Hetland Nøsen og er en
70-modell. Jeg er bosatt i
7603 Stavanger og jobber nå på
9. året som undervisninginspektør på
7604 Harestad skole i Randaberg kommune (nabokommune til Stavanger).

7608 <p
>I
2002 begynte daværende IKT-ansvarlige og jeg et arbeid på skolen
7609 med å gå over fra Win98 til... noe annet. Vi testet en rekke
7610 forskjellige løsninger, deriblant Skolelinux, men endte opp med
7611 RedHat. Skolelinux var den gang ikke modent for det vi ville ha. Jeg
7612 har siden fulgt jevnlig med på hva skolelinux holder på med, men har
7613 hele tiden vært bedre fornøyd med vår egen
"standardiserte
" løsning på
7614 RedHat/CentOS og Fedora. Vi snuser for tiden på Ubuntu som løsning på
7615 klientsiden.
</p
>
7617 <p
>I dag har vi på skolen vår en større linux-løsning med
400 klienter
7618 som kjører en blanding av LTSP (tynnklient) og DRBL (tykk klient uten
7619 harddisk) med en masse tjenere på serverrommet. Vi drifter hele
7620 sulamitten selv med webtjener, eposttjener, webmail, filtjenere,
7621 virtuelle tjenere osv. Og IT-ansvarlig har en
80% stilling som
7622 IT-ansvarlig - og så er han KoH-lærer i de resterende
20% :-)

>Du kan få en ide om hva vi holder på med om du går inn på
7625 <a href=

</a
>.
</p
>
7627 <p
>For å ta brodden av frykten for at ildsjeler gjør skolen sårbar om
7628 ildsjelene falle fra, har jeg forsikret kommunen og skolesjefen i
7629 Randaberg om at det finnes godt kommersielle tjenester vi kan benytte
7630 oss av - om det skulle bli nødvendig. Vi er tre stykker i kommunen som
7631 nå har
<strong
>god
</strong
> linux-kompetanse ift. å drifte et større
7632 system. IT-avdelingen i kommunen vil ikke ta på oss med ildtang -
7633 selv om vi nok har større IT-kompetanse mot linux enn det de selv har
7634 mot windows (de kjøper en
<strong
>masse
</strong
> konsulenttjenester
7635 fra ErgoGroup).
</p
>
7637 <p
>I kvantitet er Harestad og Grødem skole tilsammen et større
7638 IT-system enn resten av Randaberg kommune + Kvitsøy og Rennesøy, som
7639 kommunen også har driftsansvar for. Vi har som sagt rundt
800
7640 maskiner, mens kommunen med sitt driftsansvar har ansvar for rundt
500
7641 maskiner. Det er selvfølgelig litt forskjell i hvor kritiske
7642 tjenestene våre er, men det gir allikevel et litt rart bilde når
7643 IT-avdelingen overhode ikke er interessert i å snakke med oss om
7644 hvordan vi gjør ting :-)
</p

7646 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7648 <p
>Fra linux-perspektivet (ikke bare Skolelinux) er det en fordel av
7649 systemet er basert på fri programvare - og dermed fritt i ordets mange
7650 betydninger. Det er alt vi trenger: stabilt, relativt enkelt å drifte
7651 (tross alt - et større windowssystem er ikke enkelt å holde live det
7652 heller), rimelig i innkjøp og drift, og sist, men ikke minst, det er
7653 moderne for sluttbruker! Linux, i sine mange varianter,
7654 <strong
>ser
</strong
> nytt ut, fordi det hele tiden blir
7655 oppdatert. Derfor lever systemet opp til hvordan elever forventer at
7656 et moderne GUI skal være (i motsetning til WinXP :-).
</p
>
7658 <p
>Vi var veldig pragmatiske da vi begynte med linux i skolen. Det var
7659 billig, det fungerte og kunne bruke alle de gamle windows-maskinene
7660 som
"nye
" tynne klienter. I dag er vi mer bevisste fri
7661 programvare-tilhengere. Vi har oppdaget hva det er - og vi liker
7664 <p
>En av de
<strong
>store
</strong
> fordelene med fri programvare er at
7665 vi kan installere tjenester vi ønsker å tilby brukerne våre - uten å
7666 måtte tenke på om vi har råd til lisensene (fordi det er ingen). Alt
7667 vi setter i produksjon er ut i fra brukernes behov og vår kapasitet
7668 til å drifte dem. Vi skreddersyr tjenestene etter behovet og dermed
7669 trenger vi ikke ende opp med å kjøpe en pakke der vi egentlig bare var
7670 interessert i en liten del av den.
</p
>
7672 <p
>Bruk av linux frigjør ikke økonomiske midler, fordi midlene til IKT
7673 i skole er for få i utgangspunktet - men vi får så
7674 <strong
>mye
</strong
> mer igjen for dem når vi bruker en linux-løsning
7675 fremfor en windows-løsning. I praksis ser vi at vi måtte ut med det
7676 dobbelte på budsjettet vårt om vi skulle hatt en tilsvarende
7677 windows-løsning, som det vi i dag drifter med linux.

7681 <p
>Ikke all pedagogisk programvare er tilgjengelig. Det er en del
7682 programvare i skolen som er laget med utviklerverktøy som bare virker
7683 i windows, f.eks. Drillpro, LingDys/LingWrite. Det er også
7684 "programmer
" som bare virker om du har tilgang til Microsoft Office,
7685 f.eks. AskiRaski.
</p
>
7687 <p
>Vi sliter også litt med at video-codecer ikke alltid er like lett å
7688 få opp å gå på klientene. Det er alltid en eller annen videosnutt fra
7689 nrk.no som ikke er så samarbeidsvillig, uansett mediaplayer.

7693 <p

7694 bruker mest er Firefox (jobber med Chrome, fordi det er
7695 <strong

</strong

7696 over til LibreOffice), GIMP osv. Standardpakken av
7697 sluttbrukerprogrammer.

7699 <p
>På tjenernivå bruker vi OpenWebMail (skal over til Zimbra), Exim
7702 <p

7707 skoler til å ta i bruk fri programvare?

7709 <p
>Jeg er langt i fra sikker. For det første handler det mye om at
7710 IKT-avdelingen i kommunen ofte er de som styrer hva som er IKT på
7711 skolene - og de liker å bruke avtalene med Microsoft, som de garantert
7712 har fra før. Dessuten - Select
6-avtalen til skolene gjør Microsoft
7713 skvettbillig.
</p
>
7715 <p
>Vi la vekt på effektiv drift av systemet - og at vi kunne øke
7716 antall maskiner uten å måtte øke budsjett for utstyr eller personell
7717 særlig mye, enn om vi hadde gått for en Microsoft-løsning. I praksis
7718 ser vi at en ren linux-installasjon driftes til halve prisen av en
7719 Microsoft-løsning.
</p
>
7721 <p
>Vi har i praksis også sett at det lærerne (og elevene) liker er at
7722 vi tilbyr

7723 vanlige i en Microsoft-løsning. Det er ikke så vanlig at
7724 <strong

7725 også brukt som et vellykket argument mot Microsoft.

7728 det. Problemet er å få dem som har makt til å bestemme det til faktisk

7745 <p
>Jeg heter Astri Sletteng. Jeg er lærer og IKT veileder ved Håkvik
7746 skole i Narvik kommune. Min bakgrunn når det gjelder IKT: Av formell
7747 utdannelse har jeg lærerutdanning, Master i skoleledelse og IKT for
7748 lærere. Har jobba som IKT veileder siden
2002.
</p
>
7750 <p
>Det viktigste for meg som IKT veileder er å få fundamentert den
7751 5. basisferdigheten, digital kompetanse ved skolen min på en god måte
7752 slik at hele skolesamfunnet tar i bruk IKT i alle fag. Dette arbeidet
7753 gjøres i nært samarbeid med skolens ledelse.
</p
>
7755 <p
>Min viktigste jobb som IKT veileder er å være motivator og pådriver
7756 i IKT arbeidet ved skolen.

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

7760 <p
>Jobber i en kommune hvor vi satser på Fri programvare. I
2004 ble
7761 det gjort et politisk vedtak om at vi skulle innføre Skolelinux ved
7762 alle skolene i kommunen. Jeg har dermed en god del erfaring med
7763 Skolelinux, samt annen fri programvare som Open Office, Joomla, Moodle
7766 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p

7768 <p
>Siden vi jobber med åpen kildekode kan vi få programmene og
7769 produktene tilpasset vår bruk. Det er jo heller ikke en ulempe at
7770 skolen kommer bedre ut økonomisk, men først og fremst er det viktig
7771 for oss at vi har digitale systemer som gjør at vi kan følge
7772 læreplanen i alle fag. Det syns jeg at vi kan gjøre gjennom
7773 Skolelinux.
</p
>
7775 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7777 <p
>Skolen er avhengige av å ha folk på IT avdelinga i kommunen som kan
7778 drive support, og være tilgjengelige når vi trenger hjelp. Det er en
7779 ulempe at ikke alle på denne avdelingen nødvendigvis er god på
7782 <p
>Vi har også noen utfordringer når det kommer til spesielle
7783 programmer som enkelte elever er avhengige av ? og som ikke er
7784 plattform uavhengige. Her har vi i Friprog-verden, men også
7785 departement en jobb å gjøre.
</p

7787 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong

7789 <p
>Skolen vår bruker Skolelinux, Open Office, Iceweazel (Mozilla),
7790 VLC, Tux paint, Scribus, FreeMind, GIMP, digiKam, Ksnapshot, GeoGebra,
7791 Moodle (innført på alle klassetrinn + som et administrativt verktøy)
7792 og Joomla som hjemmeside.

7794 <p
>Det er de jeg kommer på i farten. I tillegg har vi Smartboard
7795 installert på server, men det regnes vel ikke som fri programvare?

7800 <p
>Først og fremst trenger skolen oppetider på sine datasystemer. Syns
7801 også at det at vi kan få tilpasset plattform og systemer til vår bruk
7802 er en god strategi å bruke.

7818 <p
>Rubén Romero y Cordero,
81-modell, deltidspappa (
50%) for en jente
7819 på
6 år. Jobber i Oslo som Global Sales Executive hos Varnish Software
7820 og til daglig har jeg kontakt med kunder fra hele verden. Min
7821 forkjærlighet for fri programvare har gjort at jeg har nå flere års
7822 erfaring med salg av slike løsninger (bl.a. fra Redpill Linpro og
7823 Freecode) og mye innsikt og kunnskap om det globale IT-markedet.
7824 Ellers er jeg involvert i flere prosjekter bl.a. er jeg Ubuntu
7825 Community medlem, kontaktpersonen for Ubuntu Norge og driveren av
7826 SpreadUbuntu marketing prosjektet og nå fersk styremedlem i FRISK. Jeg
7827 har brukt GNU/Linux siden
1997.
</p

7829 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
7831 <p
>Som Debian bruker siden slutten av
90-tallet var det uunngåelig å
7832 ikke komme bort i Skolelinux. Dette var vel i slutten av
2001 når jeg
7833 var student ved UiO. Flere år senere fikk jeg lastet og testet Venus
7834 (Skolelinux
1.0) på release dagen.
</p
>
7836 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7838 <p
>Fri programvare bygges sten for sten i det åpne, slik at koden og
7839 prosessen den lages på kan gjennomskues av andre enn de som har laget
7840 det. Det er et vitenskapelig og gjennomsiktig måte å lage programvare
7843 <p
>Skoler i vårt samfunn skal være steder hvor vitenskapelig kunnskap
7844 deles til alle. I dag har vi ikke et vitenskapelig tilnærming til
7845 hvordan programvaren som brukes på skolen lages. Skolelinux bringer
7846 inn at slik tilnærming i skoleverkets klasserom, siden
7847 operativsystemet er en åpent platform som gir skolene muligheten til å
7848 dra nytte av programvare som er laget av tusenvis av mennesker verden
7849 rundt og som gir elevene så vel som lærerne muligheten til å bruke,
7850 dele, forandre og forbedre OSet sitt uten begrensninger. I den
7851 forbindelsen representerer Skolelinux også konkrete resultater utfra
7852 samhandling på tvers av grenser.
</p
>
7854 <p
>Når det gjelder de tekniske fordelene av Skolelinux er jeg sikker
7855 på at andre enn meg har allerede beskrevet disse bedre enn det jeg
7856 kan. Men jeg kan likevel tilføye noe: Skolelinux som sådan er en
7857 community-drevet operativsystemplatform. Som i ethvert
7858 community-prosjekt har alle Skolelinux brukere muligheten til å
7859 påvirke retning av prosjektet og resultatet som gjenspeiles i
7860 programvaren. Dette kommer sjeldent frem og jeg mener at det er noe
7861 som burde fokuseres mer på.
</p
>
7863 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7865 <p
>De største ulempene er:
</p
>
7868 <li
>Mangel på kompetanse
</li
>
7869 <li
>Mangel av administrative verktøy som kunne hjelpe lokale IT
7870 avdelinger å bruke Skolelinux til mer enn bare en tjener for
7871 terminalklienter. Et eksempel: Zentyal sin web-dashboard.
</li
>
7874 <p
>Bedre og mer intuitive administrative verktøy kunne løst deler av
7875 problemet, men det er unektelig at ved bruk av Skolelinux må
7876 IT-personalet vite hva de gjør for å få ting gjort riktig, eller i det
7877 hele tatt. Med andre platformer er kompetansen enklere tilgjengelig og
7878 løsningene kan fungere på en tilfredstillende, om ikke riktig
7881 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
7883 <p
>Har brukt GNU/Linux utelukkende sommitt skrivebord OS siden
2000. I
7884 dag bruker jeg Ubuntu og gjør det meste med friprogramvare verktøyene
7885 som er tilgjengelige der. Med over
20.000 programmer å velge mellom er
7886 dette mer enn nok for de fleste brukerne.

7888 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
7889 skoler til å ta i bruk fri programvare?
</strong
></p
>
7891 <p
>Opplysning og pragmatikk. Vi prøver å løse problemer med bruk av
7892 programvare. De fleste utfordringene skolene har på IKT-siden kan
7893 løses ved hjelp av friprogramvareverktøy i dag. Det som trenges er
7894 opplysning, kunnskap og kompetanse.

</strong

7921 <p
>Skolelinux har jeg møtt ved flere anledninger opp gjennom åra, både gjennom
7922 entusiastiske skolelinuxbrukere og skeptiske
"forståsegpåere
" :-)
</p
>
7924 <p
>Jeg husker en leverandør av et stort OS for noen år siden mente at
7925 Skolelinux var kun for hackere og nerder og at ingen seriøse skoler
7926 kunne ta dette i bruk. Heldigvis er kunnskapen større nå og
7927 skikkelige
"IT-folk
" søker alltid å utvide sin kunnskap.
7929 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7931 <p
>Ja det er mange fordeler. Uavhengighet, stabilitet, åpenhet, standarder
7932 osv. Tror det er viktig at man ikke begrenser mulighetene på den plattformen
7933 elevene skal jobbe.
</p
>
7935 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7937 <p
>Det største hinderet er det vi opplever på andre områder rundt
7938 fri programvare, nemlig kunnskap. For mange er det trygt å velge det vi
7939 alltid har valgt. Fordi leverandørene rundt oss sitter på den kunnskapen og
7940 de vi støtter oss på har den samme. Hvis vi klarer å riste løs litt og
7941 glemme gamle kriger mellom operativsystemer og leverandører, men sette ned
7942 hva som er viktig og velge ut fra det, så hadde man kanskje kommet ut med
7943 litt andre resultat. Jeg tror IT-folk er konservative og velger tradisjonelt
7944 og det er synd.
</p
>
7946 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
7948 <p
>Jeg bruker Ubuntu, Android, Jolicloud, Open Office, Zimbra, Picasa
7949 og Firefox samt en bråte med tjenester som er webbasert. Det eneste
7950 som er betalingslisens for er OSX. Ser at jeg jobber mer og mer i
7951 skyen og setter pris på alt jeg slipper egen klient til. Derfor er
7952 jeg veldig sjarmert av små kjappe operativsystemer som krever minimalt
7953 av maskinvaren.

>
7955 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
7956 skoler til å ta i bruk fri programvare?
</strong
></p
>
7958 <p
>Tror en blanding av krav og informasjon er veien å gå. Krav om
7959 sikkerhet, oppetid og åpne standarder. Informasjon om muligheter og
7960 alternativer. Her har leverandører, IT-avdelinger og pedagoger en vei
7961 å gå sammen. Det er til slutt LÆRING det dreier seg om, og da må man
7962 få mest mulig læring for pengene man har.

>Sturle Sunde, ansvarleg for skulenettet i Flora kommune. Eg driv,
7980 vidareutviklar og er andrelinje brukarstøtte for datanettet ved
7981 skulane i Flora kommune.
10 skular og meir enn
700 maskiner med
7982 Linux, medrekna tynnklientar. Tidlegare jobba eg i mange år med
7983 unix-drift ved Universitetets senter for informasjonsteknologi ved
7984 Universitetet i Oslo.
</p

7986 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
7988 <p
>Det er vanskeleg å svare konkret på. Eg har drive med Unix og Linux i
7989 alle år, og Skulelinux er eit godt kjent prosjekt i miljøet. Det var
7990 først i
2008, då eg tok til i min noverande jobb, at eg fekk bruk for
7991 Skulelinux for alvor.
</p
>
7993 <p
>Jobben min skulle vere drift av eit nytt skulenett i Flora kommune,
7994 levert av eit firma eg ikkje vil reklamere for. Systemet skulle vere
7995 ferdig levert i september året før. Dette viste seg å ta mykje lenger
7996 tid, og i haustferien
2008 hadde dei endå ikkje klart å få opp ei
7997 fungerande løysing. Situasjonen var prekær for den største skulen i
7998 kommunen med meir enn
500 elevar på ungdomssteget. Skulen hadde brukt
7999 Skulelinux før, og var tilfredse med det. No hadde dei vore utan
8000 fungerande datasystem i nesten eit år. Difor fekk eg opp ein ny tenar
8001 utanfor prosjektet og installerte Skulelinux på den. Etter litt
8002 justering av konfigurasjonen med god hjelp av #skolelinux på IRC, var
8003 den nye tenaren oppe og gjekk med både tynne og halv-tjukke klientar.
8004 Autentisering gjekk mot det nye systemet, slik at elevar og lærarar
8005 framleis har same brukarnamn og passord over alt. Dette berre
8006 fungerte, og vi bestemte oss for å erstatte delar av løysinga vi
8007 skulle få levert med Skulelinux.
</p
>
8009 <p
>Det høyrer med til historia at det nye systemet eg skulle drive frå
8010 januar
2008 endå ikkje er ferdig levert. Dei jobbar med saka, seier
8011 dei, og har von om å fullføre leveransen i løpet av
2011.
</p
>
8013 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
8015 <p
>Det er veldig mange. Eg skal ta nokre få.
</p
>
8017 <p
>Den viktigaste fordelen er at det igrunn berre er ei maskin å passe
8018 på, og det er tenaren. Med andre løysingar har ein gjerne programvare
8019 og anna som skal vedlikehaldast på kvar enkelt maskin. Med Skulelinux
8020 kan alle feil rettast og alle program oppgraderast på alle maskiner
8021 samstundes ved å gjere endringa som må til på tenaren. Eg kan sitje
8022 på kontoret og passe på alle tenarane i kommunen derifrå.
</p
>
8026 <li
>Tynne klientar gjer det mogleg å bruke eldre utstyr lenge, so lenge
8027 tenaren er sterk nok. Ein liten tenar med eit par halv-moderne CPUar
8028 og
2 GiB RAM held lenge for eit typisk klasserom med
30 tynnklientar,
8029 og det er lett å utvide med fleire.
8031 <li
>Halvtjukke klientar gjer det mogleg å utnytte kapasiteten i litt
8032 nyare maskiner betre, og avlaste tenaren. Ingenting vert installert
8033 lokalt på desse heller, og harddisken kan gjerne koblast frå. Gode
8034 halvtjukke klientar kan kjøpast brukt for under
1000-lappen, og det er
8035 heile kostnaden. Ingen lisensar eller anna på toppen, og det er ikkje
8036 krav til kraftigare tenar heller.
8038 <li
>Det er Linux. Vi har ikkje noko kluss med drivarar, dei berre er
8039 der. Heller ikkje med virus, dei finst i realiteten ikkje. Eller med
8040 elevar som klussar med installert programvare, for dei klarar ikkje å
8041 øydeleggje for nokon andre enn seg sjølve.
8045 <p
>Skulelinux er lagt opp til å vere veldig lett å installere rett ut
8046 av boksen på ein heil skule av ein interessert lærar. Det er ofte ei
8047 god løysing for skulen. Å ha nokon til stades som kjenner systemet og
8048 kan forklare enkle ting eller løyse problem der og då, er uvurderleg
8049 viktig for ein stressa lærar fem minutt før det ringer inn.
</p
>
8051 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
8053 <p
>All den ferdige konfigurasjonen gjer det tungvint å tilpasse
8054 Skulelinux til eit system som skal fungere saman med mange andre
8055 installasjonar i eit felles datanett for skulane i ein kommune. Det
8056 heile er prekonfigurert for ein skule, og utviding til mange skular
8057 med eigne tenarar er ikkje berre enkelt.
</p

8059 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
8061 <p
>Eg brukar mest alle små hjelpeprogram som føl med operativsystemet,
8062 samt scriptspråket perl. Elles er Firefox/Iceweasel, Gnome-terminal
8063 og ssh i kontinuerleg bruk. Av Linux-distribusjonar brukar eg både
8064 Debian, Ubuntu, SuSE og RedHat dagleg. Eg prøvar å finne det verktyet
8065 som passar best til kvar del av jobben.

8068 skoler til å ta i bruk fri programvare?
</strong

8070 <p
>Det er to målgrupper ein må sikte mot. Det eine er alle skulane som
8071 manglar eller har eit lite tilfredsstillande opplegg i dag, og ikkje
8072 har råd til å kjøpe noko nytt og blankpussa opplegg. Der er det om å
8073 gjere å gjere det enkelt for skulane å finne Skulelinux, og gjere det
8074 enkelt for dei å få hjelp til installasjon på skulen. Gjerne med
8075 lokale kontaktpersonar. Her er det dugnadsinnsats som må til, for
8076 desse skulane har ikkje råd til å betale for dette.
</p
>
8078 <p
>Den andre og kanskje viktigare målgruppa er dei meir eller mindre
8079 profesjonelle kundane. Alle store offentlege innkjøp, inkludert
8080 innkjøp av nytt datasystem for skular, må ut på offentleg anbod.
8081 Offentlege anbod er mykje meir lukka enn dei gjev inntrykk av, og både
8082 regelboka og boka med triks for å sminke tilbodet er tjukk. Det er
8083 vanskeleg å komme inn utan eit solid salsapparat i ryggen. Kanskje
8084 Skulelinux skulle prøve aktivt å få seg eit partnarskap med eit av dei
8085 store som gjerne vil sterkare inn på den offentlege IT-marknaden?
8086 Nokon som kjenner triksa og har krefter til å ta opp kampen mot både
8087 dårlege anbod og Rudolf Blostrupmoen IT AS. Leveranse til skulane i
8088 ein kommune er ein god måte å få ein fot inn døra som leverandør til
8089 ein lukrativ kommunemarknad som kjøper alle tenester. Ta kontakt med
8090 nokon som er passeleg store og ikkje er Microsoft-partnar, og fortell:
8091 «Vi har eit ferdig produkt som du kan selje. Nei vi skal ikkje ha for
8092 det. Du kan gjerne gjere kva du vil med det, berre vi får lov til å
8093 hjelpe deg. Målgruppa er alle kommunar, og det er noko dei vil ha.
8094 Det er eit godt produkt, brukt av mange og godt likt.»

>Jeg leste en artikkel om en dugnadsinstallasjon av Skolelinux på en
8121 skole på Jæren et sted. Tanken om dugnad og frihet appellerte til
8122 meg. Da vi skulle bygge ny skole var det en del vi måtte spare på,
8123 fordi vi beveget oss mot en kostnadssprekk. Kabling og investering i
8124 PC-er var en av tingene vi sparte på. Derfor kjøpe vi
72 pc-er for
390
8125 pr stk. En filtjener og en applikasjonsserver.

>Fordelen er at så mye er satt opp fra starten. I tillegg er det
8130 tydelig at pakka er laga for skoleverket. Brukerne har egne
8131 skrivebord, tilgang på mange gode verktøyprogrammer. Vi slipper å
8132 tenke på virus. Brukerne har ikke mulighet til å ødelegge
8133 klientoppsett, men har gode muligheter til å endre eget oppsett. Dette
8134 tror jeg er inspirerende og kjekt for mange brukere. Mappestrukturen
8135 er ferdig og det er
"enkelt
" å designe lokale mappestrukturer via
8136 skeleton. Noen av oss i skoleverket mener skolen skal være en
8137 "mot-kultur
". Da er Skolelinux et av valgene man kan ta. Et annet er å
8138 spise på indisk restaurant i stedet for Mc Donald
's når vi er på bytur
8139 osv.. Ordene deling, frihet, dugnad osv er positive ord i
8140 skoleverket. Det er viktig at elevene blir bevisst dette.

>Kompabiliteten er selvsagt et problem, selv om det er mindre nå enn
8145 før. For IKT-personer på skolene som skal drifte dette er det
8146 problematisk med kommandoer i terminalen. I tillegg er det alt for
8147 mange programmer i Skolelinux som ikke blir brukt. Jeg tror
8148 Skolelinux er tjent med å tone ned begrepet pedagogisk programvare.
8149 Slik jeg ser det finnes ikke denne kategorien programmer lengre slik
8150 de gjorde før, som frittsående programmer som installeres på en
8151 datamaskin eller på serveren. Det finnes en del spesialpedagogiske
8152 programmer, som Textpilot, LingDys, LingRight, AskiRaski, Ny i Norge
8153 osv. Men dette er programmer for enkelt-elever eller små grupper av
8154 elever. Det som bør være fokus er at alle undervisningsressurser som
8155 lages for nettet skal være nettleseruavhengig.

8159 <p
>OpenOffice bruker jeg til vanlig kontorarbeide. VLC bruker jeg som
8160 videoavspiller og av og til streaming av film. Gimp bruker jeg i
8161 undervisningen til bildemanipulering. Firefox og Chrome er mine
8162 favoritt-nettlesere. Firefox har lenge vært førstevalget mitt, nå
8163 bruker jeg mest Chrome. Opplever den som raskere og smidigere enn
8164 Firefox. Ubuntu bruker jeg som dualboot på jobb-maskinen min i
8165 tillegg til at alle PCer hjemme har en eller annen Ubuntu-distribusjon
8166 installert. Jeg bruker Clonezilla på Ubuntu
10.04 til kloning av
8167 datamaskiner på jobb. Det er selvsagt en haug andre frie programmer
8168 jeg bruker men jeg bruker dem ikke daglig. Jeg kan ramse opp:
8169 recordmydesktop, cinelerra, acidrip, soundjuicer, audacity, NX
8170 (no-machine), Kino, Rythmbox...

</strong
></p
>
8175 <p
>Jeg tror oppsøkende virksomhet er den rette strategien.
8176 Ressurspersoner gjør avtaler med rådmenn, skolesjefer, rektorer. Det
8177 er slik konkurrentene gjør det. Fokuset i slike samtaler bør være
8178 kost-nytte. Dersom personer med økonomisk ansvar ser at de kan få
8179 like godt tilbud til mindre utgifter, tror jeg det er mulighet til å
8180 få innpass. Dersom de også kan få konkrete tilbud på drift i slike
8181 samtaler, vil de kanskje bli litt mer interesserte i hvor mye penger
8182 som faktisk går til IKT i skolene. Det er også viktig at vi ikke
8183 firer for mye på krav til datamaskiner. Det er flott at Skolelinux
8184 går på
"utrangert
" utstyr, men dette bør bare presenteres som et
8185 alternativ. Skolelinux-installasjoner med utrangert utstyr er ikke å
8186 foretrekke dersom man kan unngå det. Det skaper ikke entusiasme hos
8187 brukerne (elever og lærere) når de bruker gamle datamaskiner som går
8188 tregt. Det er kjempefint med skoler som har kommet seg frem til
8189 Skolelinux og fri programvare av seg selv, men de lever på nåde.
8190 Slike valg må fundamenteres hos skoleeier.

8221 <p
>Gjennom en eller annen nettavis i
2001 der var det skrevet om
8222 Skolelinux. Artikkelen ga meg lyst til å prøve ut systemet.
</p

8224 <p
>Det startet i
2002 ved at jeg installerte en av de første utgavene
8225 av Skolelinux på en standard pc på Solneset skole i Tromsø. Denne var
8226 oppe fram til desember
2003 da jeg sluttet på den skolen og begynte i
8227 ny jobb i Narvik kommune.

8229 <p
> I Narvik kommune var det i
2004 kun
2 servere på da totalt
15
8230 skoler. Disse var Windows NT baserte. På disse to skolene var det lite
8231 med maskiner. Jobben med å få Narvik Kommune opp på akseptabelt nivå
8232 virket å være formidabel. Men med hjelp av gode kollegaer og leder
8233 skrev jeg en IKT plan for Narvik kommune som ble vedtatt av politikere
8234 i august
2004. I denne planen ble det bestemt at Narvik kommune skulle
8235 bruke Skolelinux. Her ble det også satt av midler til kabling av god
8236 infrastruktur på alle skoler samt innkjøp av nye datamaskiner. Så i
8237 dag har vi
17 servere hvorav
13 er på Skolelinux, med ca
1500 klienter
8238 basert på tynne,
"halvtykke
" og et stort antall bærbare pcer basert på

8321 men det virker ut som det ikke skjer noe mer på. I tillegg var vi med

8329 en arkitektur med sentral-drift som gir mange driftfordeler. I

8371 <br

8373 <p
>Kommunen min har to omtrent jevnstore tettsteder, og en
8374 ungdomsskole i hvert av tettstedene. Den minste av disse har ca
300
8375 elever og til denne sogner det
3 barneskoler. Den største har ca
350
8376 elever og til denne sogner det
4 barneskoler.
</p
>
8380 <li
>Kommunen har i veldig lang tid forsømt IKT i skolen, og det har
8381 bare blitt gitt smuler i ny og ne. Det er kun den største av
8382 ungdomsskolene som har hatt en skikkelig datapark, og dette takket
8383 være en naturfaglærer som ble lei av å vente på kommunen. Det gjorde
8384 at vi bestemte oss for å ta ting i egne hender, og da vha
8385 skolelinux. En testinstallasjon med
10 gamle PCer ble gjort, og vi så
8386 raskt at dette var veldig lovende. Neste etappe var å gi alle lærere
8387 egen PC på arbeidsplassene sine (
2004), og så sette opp
16 PCer på to
8388 datarom. Vi har kun basert oss på å kjøpe inn brukte maskiner, og
8389 aldri dyrere enn
1000 kr pr klient. For to år siden så hadde vi
8390 klienter i alle klasserom, og totalt hadde vi da rundt
250 stk. Rundt
8391 40 klienter brukes av lærerne og kjører på en egen server. Elvene har
8392 resten, og kjører også en egen server. Servere har vi også kjøpt
8393 brukt,
2 år gamle servere koster
6-
7000 kroner.
</li
>
8395 <li
>Skolen vår er et relativt gammelt bygg, men en meget dyktig
8396 vaktmester har sammen med IKT-ansvarlig/Naturfaglærer lagt kabler til alle
8397 rom. Gradvis har vi byttet ut billige svitsjer med mer solide saker
8398 som er mulig å fjernstyre.
</li
>
8400 <li
>Vi har i all hovedsak greid å få dette til over eget budsjett, men
8401 vi har også passet på å få penger når de andre skolene har fått
8402 bærbare PCer til lærere osv.
</li

8404 <li
>Vår IKT-ansvarlig har gjort (og gjør) en fenomenal jobb, og vi har
8405 en maskinpark som de andre av kommunens skoler bare kan drømme
8410 <p
>Så skjer det som ofte skjer. Det kommer en eller annen
8411 selger/blåruss og skal fikse ALT. I vårt tilfelle betyr dette også
8412 sentralisering av drift. Den ny-ansatte på kommunens IT-avdelingen
8413 skal også ha jobb, og ser for seg å ta over skoledriften. Kommunen
8414 kjøper inn eksterne driftstjenester, og nekter i samme slengen å ta
8415 hensyn til skolen vår. Dette til tross for at vi alene har like mange
8416 datamaskiner som de andre til sammen.
</p
>
8420 <li
>Det blir krevd at vi skal innlemmes i de kommunale systemet, og
8421 det er VI som får ansvar for at dette kommer på plass. Og det er her
8422 de horrible tingene begynner å skje.

8425 hente epost for våre ansatte. Og det kreves at vi finner løsning på

8429 at vi må bruke en terminalløsning mot kommunal server. Ikke i seg selv
8430 et problem i følge IKT-ansvarlig hos oss. Men kommunens IT-avd nektet
8431 faktisk å åpne de porter OSV som vi måtte bruke.
</li
>
8433 <li
>Vi blir pålagt å flytte på innsiden av det kommunale
8434 nettverket. Dette gjorde at vi mistet hjemmekontor for lærere og
8435 elever. Å få åpnet porter i kommunal brannmur var ikke
8436 aktuelt. Mulighet for fjerndrift ble også vekk i samme slengen.
</li
>
8438 <li
>Vår LMS Moodle er ikke mulig å nå for elevene og lærerne.
8442 <p
>Den andre ungdomsskolen i kommunen begynner så å kreve at de skal
8443 få bedre datatetthet, og komme opp på et nivå som ligner det vi
8444 har. De ser at vi kan avholde eksamen hvor alle
10. klassingene får
8445 sitte ved hver sin PC. Og de har fått tilbakemelding (klager) fra VGS
8446 om manglende datakompetanse på elevene som kommer fra dem. Dette fører
8447 videre til at kommunen endelig innser at de må ta grep.
</p
>
8449 <p
>Grepet betyr sentralisering, og farvel til vår plattform får vi
8450 høre. Det blir gjort en rekke bestemmelser og vedtak som vi ikke får
8451 være en del av. Det blir helt klart at vi må redusere antall maskiner,
8452 og det skal satses på bærbare maskiner. Siden vi ikke har fått tatt
8453 del i prosessene som angår oss, så bruker vi fagforening. Vi har ikke
8454 blitt hørt i forbindelse med endringer som er betydelig for vår
8455 hverdag, og greier å stoppe omlegging. I tillegg så har vi et politisk
8456 vedtak i kommunen på at vi skal kjøre Linux på elevnett, og dette
8457 vedtaket kan ikke administrasjonen i kommunene helt uten videre
8458 tilsidesette.

8460 <p

8461 runder i kommunens kontrollutvalg har gjort det tydelig at vi har blitt
8462 systematisk motarbeidet.

8486 men med omgivelsene rundt som vil oss til livs. Men det har vært verdt

8543 <p
>Jeg glemte å nevne at vi nå nesten ikke bruker tid på å drifte
8544 systemet vårt, noe som gjør at det aller meste av tid blir brukt til å
8545 støtte lærerne og elevene. F.eks så bruker vår IKT-ansvarlig den
8546 første timen på jobb,
0730-
0830 kun til å gå ute på arbeidsplassene
8547 til læreren. Dette for å kunne svare på små og store problem, gi tips
8548 og råd, eller bare for å plukke opp hva som er behovet ute i
8549 undervisningsarealene. Det er dessverre ikke slik at alle lærerne har
8550 nok digital kompetanse til å kunne formulere alle spørsmålene de har,
8551 men ved å kunne få vise eller lufte tanker med IKT-ansvarlig så er det
8552 utrolig hva som kommer fram.
</p

8556 <li
>Jeg ser at mange bruker økonomi som argument i forhold til å bruke
8557 SkoleLinux, og jeg skal ikke legge skjul på at det var dette som i
8558 utgangspunktet var årsaken til vårt valg. Men diskusjonene og kampen
8559 med kommunens IT-avdeling har gjort at vi har fått et noe annet
8560 fokus. Fordelene med drift og stabilitet, gjør at vi ville ha valgt
8561 samme løsning selv om den var dyrere. At vi slipper langt billigere
8562 unna, som følge av
0,- lisenskostnader og lave maskinvarekostnader, er
8563 bare en bonus.
</li
>
8565 <li
>Etter å ha kranglet oss til å få skikkelig oversikt over hva de
8566 andre skolene i kommunen bruker på IT, så har vi fått gehør for å få
8567 samme midler til innkjøp. Dette har gjort at vi nå kan kjøpe inn
8568 utstyr som de andre skolene bare kan se langt etter. Vi har nettopp
8569 kjøpt inn
3 videokamera i semiproff-klassen for å kunne lage film,
8570 samt sende live fra skoleteater/konserter. Vi har kjøpt inn digitale
8571 kompaktkamera til alle klassene. Vi har et team av lærere som skal i
8572 gang med å teste ut tablets på svake elever. Håpet et at teknologien
8573 kan være med på å gi noen av elevene litt mer motivasjon. Vi har kjøpt
8574 inn et halvt klassesett med pulsklokker, noe som har vist seg å være
8575 overraskende inspirerende for en del av elevene. Vi har også oss på
8576 fag på en høyskole litt lengre sør for oss, slik at
3 av oss nå skal
8577 ta faget
"Linux tjenestedrift
". Som inspektør og en del av skolens
8578 administrasjon er det veldig praktisk å kunne trå til hvis det
8579 kniper. Men IKT-ansvarlig har vært UTROLIG flink til å lage rene
8580 smørbrødlister for hvordan de mest vanlige driftsproblem løses, så det
8581 er lett for flere av oss å ta del i den daglige driften. Vi har svært
8582 stor nytte av lærling (som også hjelper to av naboskolene), men det er
8583 nesten blitt slik at det er om å gjøre å komme til først for å få løse
8584 problem. Det å få fingrene på problem og utfordringer er den aller
8585 beste læremester.

8598 håper at vi nå framover kan få tid til å bidra. Vi er i ferd med å
8599 bytte ut en av serverne våre, og da vil denne trolig bli satt opp som
8600 testserver for neste versjon av Skolelinux. På den måten vil vi i alle
8601 fall kunne gi tilbakemeldinger og rapportere feil. I tillegg så vil
8602 det kanskje gi oss noen nye utfordringer, for som lærlingen vår sier:

8630 perhaps inspire others to test hardware as well. To test, I PXE

8632 a few applications and plug in selected pieces of hardware. When
8633 something fail, I make a note about this in the test matrix and move
8634 on. If I have some spare time I try to report the bug to the OS
8635 vendor, but as I only have the machines for a short time, I rarely
8636 have the time to do this for all the problems I find.

8735 <description><p
>In the latest issue of Linux Journal, the readers choices were
8736 presented, and the winner among the multimedia player were VLC.
8737 Personally, I like VLC, and it is my player of choice when I first try
8738 to play a video file or stream. Only if VLC fail will I drag out
8739 gmplayer to see if it can do better. The reason is mostly the failure
8740 model and trust. When VLC fail, it normally pop up a error message
8741 reporting the problem. When mplayer fail, it normally segfault or
8742 just hangs. The latter failure mode drain my trust in the program.
<p
>
8744 <p
>But even if VLC is my player of choice, we have choosen to use
8745 mplayer in
<a href=
"http://www.skolelinux.org/
">Debian
8746 Edu/Skolelinux
</a
>. The reason is simple. We need a good browser
8747 plugin to play web videos seamlessly, and the VLC browser plugin is
8748 not very good. For example, it lack in-line control buttons, so there
8749 is no way for the user to pause the video. Also, when I
8750 <a href=
"http://wiki.debian.org/DebianEdu/BrowserMultimedia
">last
8751 tested the browser plugins
</a
> available in Debian, the VLC plugin
8752 failed on several video pages where mplayer based plugins worked. If
8753 the browser plugin for VLC was as good as the gecko-mediaplayer
8754 package (which uses mplayer), we would switch.
</P
>
8756 <p
>While VLC is a good player, its user interface is slightly
8757 annoying. The most annoying feature is its inconsistent use of
8758 keyboard shortcuts. When the player is in full screen mode, its
8759 shortcuts are different from when it is playing the video in a window.
8760 For example, space only work as pause when in full screen mode. I
8761 wish it had consisten shortcuts and that space also would work when in
8762 window mode. Another nice shortcut in gmplayer is [enter] to restart
8763 the current video. It is very nice when playing short videos from the
8764 web and want to restart it when new people arrive to have a look at
8765 what is going on.

9232 migration. It uses qemu-img from the qemu package to make the disk
9233 image, parted to partition it, losetup and kpartx to present the disk
9234 image partions as devices, and dd to copy the data. I NFS mounted the
9235 new servers storage area on the old server to do the migration.

9534 TB zfs volume we currently use to store DV video. Because of this, I
9535 finally got around to do a test installation of Debian/Squeeze with
9536 kfreebsd. Installation went fairly smooth, thought I noticed some
9537 visual glitches in the cdebconf dialogs (black cursor left on the
9538 screen at random locations). Have not gotten very far with the
9539 testing. Noticed cfdisk did not work, but fdisk did so it was not a
9540 fatal problem. Have to spend some more time on it to see if it is
9541 useful as a file server for NUUG. Will try to find time to set up a
9542 gnash buildbot slave on the Debian Edu/Skolelinux this weekend.

>Prioritising packages for the Debian Edu /

"http://www.skolelinux.org/
">Skolelinux
</a
> DVD, which is
9553 supposed provide a school with all the services and user applications
9554 needed on the pupils computer network has always been hard. Even
9555 schools without Internet connections should be able to get Debian Edu
9556 working using this DVD.
</p
>
9558 <p
>The job became a lot harder when apt and aptitude started
9559 installing recommended packages by default. We want the same set of
9560 packages to be installed when using the DVD and the netinst CD, and
9561 that means all recommended packages need to be on the DVD. I created
9562 a patch for debian-cd in
<a href=
"http://bugs.debian.org/
601203">BTS
9563 report #
601203</a
> to do this, and since this change was applied to
9564 the Debian Edu DVD build, we have been seriously short on space.
</p
>
9566 <p
>A few days ago we decided to drop blender, wxmaxima and kicad from
9567 the default installation to save space on the DVD, believing that
9568 those needing these applications are few and can get them from the
9569 Debian archive.
</p
>
9571 <p
>Yesterday, I had a look what source packages to see which packages
9572 were using most space. A few large packages are well know;
9573 openoffice.org, openclipart and fluid-soundfont. But I also
9574 discovered that lilypond used
106 MiB and fglrx-driver used
53 MiB.
9575 The lilypond package is pulled in as a dependency for rosegarden, and
9576 when looking a bit closer I discovered that
99 MiB of the
106 MiB were
9577 the documentation package, which is recommended by the binary package.
9578 I decided to drop this documentation package from our DVD, as most of
9579 our users will use the GUI front-ends and do not need the lilypond
9580 documentation. Similarly, I dropped the non-free fglrx-driver package
9581 which might be installed by d-i when its hardware is detected, as the
9582 free X driver should work.
</p
>
9584 <p
>With this change, we finally got space for the LXDE and Gnome
9585 desktop packages as well as the language specific packages making the
9586 DVD more useful again.

9598 raise money for the project is going well. The lower limit of
10
9599 signers was reached in
24 hours, and so far
13 people have signed it.
9600 More signers and more funding is most welcome, and I am really curious
9601 how far we can get before the time limit of December
24 is reached.
9604 <p
>On the #gnash IRC channel on irc.freenode.net, I was just tipped
9605 about what appear to be a great code coverage tool capable of
9606 generating code coverage stats without any changes to the source code.

9610 It is missing in Debian, but the git source built just fine in Squeeze
9611 after I installed libelf-dev, libdwarf-dev, pkg-config and
9612 libglib2.0-dev. Failed to build in Lenny, but suspect that is
9613 solvable. I hope kcov make it into Debian soon.

9621 school, including central infrastructure server, workstations, thin
9622 client servers and diskless workstations. A nice touch added
9623 yesterday is RDP support on the thin client servers, for windows
9624 clients to get a Linux desktop on request.

9635 second most popular used package that is missing in Debian. The sixth
9636 most popular is flashplayer-mozilla. This is a clear indication that
9637 working flash is important for Debian users. Around
10 percent of the

9645 schools experienced with
<a href=
"http://www.skolelinux.org/
">Debian
9646 Edu/Skolelinux
</a
> was the lack of working Flash. A lot of educational
9647 web sites require Flash to work, and lacking working Flash support in
9648 the web browser and the problems with installing it was perceived as a
9649 good reason to stay with Windows.
</p

9651 <p
>I once saw a funny and sad comment in a web forum, where Linux was
9652 said to be the retarded cousin that did not really understand
9653 everything you told him but could work fairly well. This was a
9654 comment regarding the problems Linux have with proprietary formats and
9655 non-standard web pages, and is sad because it exposes a fairly common
9656 understanding of whose fault it is if web pages that only work in for
9657 example Internet Explorer
6 fail to work on Firefox, and funny because
9658 it explain very well how annoying it is for users when Linux
9659 distributions do not work with the documents they receive or the web
9660 pages they want to visit.
</p
>
9662 <p
>This is part of the reason why I believe it is important for Debian
9663 and Debian Edu to have a well working Flash implementation in the
9664 distribution, to get at least popular sites as Youtube and Google
9665 Video to working out of the box. For Squeeze, Debian have the chance
9666 to include the latest version of Gnash that will make this happen, as
9667 the new release
0.8.8 was published a few weeks ago and is resting in
9668 unstable. The new version work with more sites that version
0.8.7.
9669 The Gnash maintainers have asked for a freeze exception, but the
9670 release team have not had time to reply to it yet. I hope they agree
9671 with me that Flash is important for the Debian desktop users, and thus
9672 accept the new package into Squeeze.

9846 <description><p
>As reported earlier, the last few days I have looked at how Debian
9847 Edu clients are configured, and tried to get rid of all hardcoded
9848 configuration settings on the clients. I believe the work to be
9849 mostly done, and the clients seem to work just fine with dynamically
9850 generated configuration.
</p
>
9852 <p
>What is the point, you might ask? The point is to allow a Debian
9853 Edu desktop to integrate into an existing network infrastructure
9854 without any manual configuration.
</p
>
9856 <p
>This is what happens when installing a Debian Edu client here at
9857 the University of Oslo using PXE. With the PXE installation, I am
9858 asked for language (Norwegian Bokmål), locality (Norway) and keyboard
9859 layout (no-latin1), Debian Edu profile (Roaming Workstation), if I
9860 accept to reformat the hard drive (yes), if I want to submit info to
9861 popcon.debian.org (no) and root password (secret). After answering
9862 these questions, the installer goes ahead and does its thing, and
9863 after around
50 minutes it is done. I press enter to finish the
9864 installation, and the machine reboots into KDE. When the machine is
9865 ready and kdm asks for login information, I enter my university
9866 username and password, am told by kdm that a local home directory has
9867 been created and that I must log in again, and finally log in with the
9868 same username and password to the KDE
4.4 desktop. At no point during
9869 this process did it ask for university specific settings, and all the
9870 required configuration was dynamically detected using information
9871 fetched via DHCP and DNS. The roaming workstation is now ready for
9874 <p
>How was this done, you might wonder? First of all, here is the
9875 list of things that need to be configured on the client to get it
9876 working properly out of the box:
</p
>
9879 <li
>IP address/netmask and DNS server.
</li
>
9880 <li
>Web proxy URL.
</li
>
9881 <li
>LDAP server for NSS directory information (user, group, etc).
</li
>
9882 <li
>Kerberos server for PAM password checking.
</li
>
9883 <li
>SMB mount point to access the network home directory. (*)
</li
>
9884 <li
>Central syslog server to send syslog messages to. (*)
</li
>
9885 <li
>Sitesummary collector URL to submit info to central server. (*)
</li
>
9888 <p
>(Hm, did I forget anything? Let me knew if I did.)
</p
>
9890 <p
>The points marked (*) are not required to be able to use the
9891 machine, but needed to provide central storage and allowing system
9892 administrators to track their machines. Since yesterday, everything
9893 but the sitesummary collector URL is dynamically discovered at boot
9894 and installation time in the svn version of Debian Edu.
</p
>
9896 <p
>The IP and DNS setup is fetched during boot using DHCP as usual.
9897 When a DHCP update arrives, the proxy setup is updated by looking for
9898 http://wpat/wpad.dat and using the content of this WPAD file to
9899 configure the http and ftp proxy in /etc/environment and
9900 /etc/apt/apt.conf. I decided to update the proxy setup using a DHCP
9901 hook to ensure that the client stops using the Debian Edu proxy when
9902 it is moved outside the Debian Edu network, and instead uses any local
9903 proxy present on the new network when it moves around.
</p
>
9905 <p
>The DNS names of the LDAP, Kerberos and syslog server and related
9906 configuration are generated using DNS information at boot. First the
9907 installer looks for a host named ldap in the current DNS domain. If
9908 not found, it looks for _ldap._tcp SRV records in DNS instead. If an
9909 LDAP server is found, its root DSE entry is requested and the
9910 attributes namingContexts and defaultNamingContext are used to
9911 determine which LDAP base to use for NSS. If there are several
9912 namingContexts attibutes and the defaultNamingContext is present, that
9913 LDAP subtree is used as the base. If defaultNamingContext is missing,
9914 the subtrees listed as namingContexts are searched in sequence for any
9915 object with class posixAccount or posixGroup, and the first one with
9916 such an object is used as the LDAP base. For Kerberos, a similar
9917 search is done by first looking for a host named kerberos, and then
9918 for the _kerberos._tcp SRV record. I
've been unable to find a way to
9919 look up the Kerberos realm, so for this the upper case string of the
9920 current DNS domain is used.
</p
>
9922 <p
>For the syslog server, the hosts syslog and loghost are searched
9923 for, and the _syslog._udp SRV record is consulted if no such host is
9924 found. This algorithm works for both Debian Edu and the University of
9925 Oslo. A similar strategy would work for locating the sitesummary
9926 server, but have not been implemented yet. I decided to fetch and
9927 save these settings during installation, to make sure moving to a
9928 different network does not change the set of users being allowed to
9929 log in nor the passwords required to log in. Usernames and passwords
9930 will be cached by sssd when the user logs in on the Debian Edu
9931 network, and will not change as the laptop move around. For a
9932 non-roaming machine, there is no caching, but given that it is
9933 supposed to stay in place it should not matter much. Perhaps we
9934 should switch those to use sssd too?
</p
>
9936 <p
>The user
's SMB mount point for the network home directory is
9937 located when the user logs in for the first time. The LDAP server is
9938 consulted to look for the user
's LDAP object and the sambaHomePath
9939 attribute is used if found. If it isn
't found, the home directory
9940 path fetched from NSS is used instead. Assuming the path is of the
9941 form /site/server/directory/username, the second part is looked up in
9942 DNS and used to generate a SMB URL of the form
9943 smb://server.domain/username. This algorithm works for both Debian
9944 edu and the University of Oslo. Perhaps there are better attributes
9945 to use or a better algorithm that works for more sites, but this will
9946 do for now. :)
</p
>
9948 <p
>This work should make it easier to integrate the Debian Edu clients
9949 into any LDAP/Kerberos infrastructure, and make the current setup even
9950 more flexible than before. I suspect it will also work for thin
9951 client servers, allowing one to easily set up LTSP and hook it into a
9952 existing network infrastructure, but I have not had time to test this
9955 <p
>If you want to help out with implementing these things for Debian
9956 Edu, please contact us on debian-edu@lists.debian.org.
</p
>
9958 <p
>Update
2010-
08-
09: Simon Farnsworth gave me a heads-up on how to
9959 detect Kerberos realm from DNS, by looking for _kerberos TXT entries
9960 before falling back to the upper case DNS domain name. Will have to
9961 implement it for Debian Edu. :)

9970 <description><p
>A few years ago, I was involved in a project planning to use
9971 Windows file servers as home directory servers for Debian
9972 Edu/Skolelinux machines. This was thought to be no problem, as the
9973 access would be through the SMB network file system protocol, and we
9974 knew other sites used SMB with unix and samba as the file server to
9975 mount home directories without any problems. But, after months of
9976 struggling, we had to conclude that our goal was impossible.
</p
>
9978 <p
>The reason is simply that while SMB can be used for home
9979 directories when the file server is Samba running on Unix, this only
9980 work because of Samba have some extensions and the fact that the
9981 underlying file system is a unix file system. When using a Windows
9982 file server, the underlying file system do not have POSIX semantics,
9983 and several programs will fail if the users home directory where they
9984 want to store their configuration lack POSIX semantics.
</p
>
9986 <p
>As part of this work, I wrote a small C program I want to share
9987 with you all, to replicate a few of the problematic applications (like
9988 OpenOffice.org and GCompris) and see if the file system was working as
9989 it should. If you find yourself in spooky file system land, it might

>A few days ago, I
10202 <a href=
"http://people.skolelinux.org/pere/blog/Debian_Edu_roaming_workstation___at_the_university_of_Oslo.html
">tried
10203 to install
</a
> a Roaming workation profile from Debian Edu/Squeeze
10204 while on the university network here at the University of Oslo, and
10205 noticed how much had to change to get it operational using the
10206 university infrastructure. It was fairly easy, but it occured to me
10207 that Debian Edu would improve a lot if I could get the client to
10208 connect without any changes at all, and thus let the client configure
10209 itself during installation and first boot to use the infrastructure
10210 around it. Now I am a huge step further along that road.
</p
>
10212 <p
>With our current squeeze-test packages, I can select the roaming
10213 workstation profile and get a working laptop connecting to the
10214 university LDAP server for user and group and our active directory
10215 servers for Kerberos authentication. All this without any
10216 configuration at all during installation. My users home directory got
10217 a bookmark in the KDE menu to mount it via SMB, with the correct URL.
10218 In short, openldap and sssd is correctly configured. In addition to
10219 this, the client look for http://wpad/wpad.dat to configure a web
10220 proxy, and when it fail to find it no proxy settings are stored in
10221 /etc/environment and /etc/apt/apt.conf. Iceweasel and KDE is
10222 configured to look for the same wpad configuration and also do not use
10223 a proxy when at the university network. If the machine is moved to a
10224 network with such wpad setup, it would automatically use it when DHCP
10225 gave it a IP address.
</p
>
10227 <p
>The LDAP server is located using DNS, by first looking for the DNS
10228 entry ldap.$domain. If this do not exist, it look for the
10229 _ldap._tcp.$domain SRV records and use the first one as the LDAP
10230 server. Next, it connects to the LDAP server and search all
10231 namingContexts entries for posixAccount or posixGroup objects, and
10232 pick the first one as the LDAP base. For Kerberos, a similar
10233 algorithm is used to locate the LDAP server, and the realm is the
10234 uppercase version of $domain.
</p
>
10236 <p
>So, what is not working, you might ask. SMB mounting my home
10237 directory do not work. No idea why, but suspected the incorrect
10238 Kerberos settings in /etc/krb5.conf and /etc/samba/smb.conf might be
10239 the cause. These are not properly configured during installation, and
10240 had to be hand-edited to get the correct Kerberos realm and server,
10241 but SMB mounting still do not work. :(
</p
>
10243 <p
>With this automatic configuration in place, I expect a Debian Edu
10244 roaming profile installation would be able to automatically detect and
10245 connect to any site using LDAP and Kerberos for NSS directory and PAM
10246 authentication. It should also work out of the box in a Active
10247 Directory environment providing posixAccount and posixGroup objects
10248 with UID and GID values.

>The new roaming workstation profile in Debian Edu/Squeeze is fairly
10261 similar to the laptop setup am I working on using Ubuntu for the
10262 University of Oslo, and just for the heck of it, I tested today how
10263 hard it would be to integrate that profile into the university
10264 infrastructure. In this case, it is the university LDAP server,
10265 Active Directory Kerberos server and SMB mounting from the Netapp file
10268 <p
>I was pleasantly surprised that the only three files needed to be
10269 changed (/etc/sssd/sssd.conf, /etc/ldap.conf and
10270 /etc/mklocaluser.d/
20-debian-edu-config) and one file had to be added
10271 (/usr/share/perl5/Debian/Edu_Local.pm), to get the client working.
10272 Most of the changes were to get the client to use the university LDAP
10273 for NSS and Kerberos server for PAM, but one was to change a hard
10274 coded DNS domain name in the mklocaluser hook from .intern to
10277 <p
>This testing was so encouraging, that I went ahead and adjusted the
10278 Debian Edu scripts and setup in subversion to centralise the roaming
10279 workstation setup a bit more and avoid the hardcoded DNS domain name,
10280 so that when I test this tomorrow, I expect to get away with modifying
10281 only /etc/sssd/sssd.conf and /etc/ldap.conf to get it to use the
10282 university servers.
</p
>
10284 <p
>My goal is to get the clients to have no hardcoded settings and
10285 fetch all their initial setup during installation and first boot, to
10286 allow them to be inserted also into environments where the default
10287 setup in Debian Edu has been changed or as with the university, where
10288 the environment is different but provides the protocols Debian Edu

>The last few months me and the other Debian Edu developers have
10418 been working hard to get the Debian/Squeeze based version of Debian
10419 Edu/Skolelinux into shape. This future version will use Kerberos for
10420 authentication, and services are slowly migrated to single signon,
10421 getting rid of password questions one at the time.

10423 <p
>It will also feature a roaming workstation profile with local home
10424 directory, for laptops that are only some times on the Skolelinux
10425 network, and for this profile a shortcut is created in Gnome and KDE
10426 to gain access to the users home directory on the file server. This
10427 shortcut uses SMB at the moment, and yesterday I had time to test if
10428 SMB mounting had started working in KDE after we added the cifs-utils
10429 package. I was pleasantly surprised how well it worked.

10468 <p
>As a step to try to see if it possible to merge the DNS and DHCP
10469 LDAP objects, I have had a look at how the packages pdns-backend-ldap
10470 and dhcp3-server-ldap in Debian use the LDAP server. The two
10471 implementations are quite different in how they use LDAP.
</p

10473 To get this information, I started slapd with debugging enabled and
10474 dumped the debug output to a file to get the LDAP searches performed
10475 on a Debian Edu main-server. Here is a summary.

>PowerDNS have two modes of operation using LDAP as its backend.
10484 One
"strict
" mode where the forward and reverse DNS lookups are done
10485 using the same LDAP objects, and a
"tree
" mode where the forward and
10486 reverse entries are in two different subtrees in LDAP with a structure
10487 based on the DNS names, as in tjener.intern and
10488 2.2.0.10.in-addr.arpa.
</p
>
10490 <p
>In tree mode, the server is set up to use a LDAP subtree as its
10491 base, and uses a
"base

10492 "dc=tjener,dc=intern,

" with a filter for
10495 "(associateddomain=

10496 forward entries, it is looking for attributes named dnsttl, arecord,

>Vagrant mentioned on IRC today that ltsp_config now support
10845 sourcing files from /usr/share/ltsp/ltsp_config.d/ on the thin
10846 clients, and that this can be used to fetch configuration from LDAP if
10847 Debian Edu choose to store configuration there.
</p
>
10849 <p
>Armed with this information, I got inspired and wrote a test module
10850 to get configuration from LDAP. The idea is to look up the MAC
10851 address of the client in LDAP, and look for attributes on the form
10852 ltspconfigsetting=value, and use this to export SETTING=value to the
10853 LTSP clients.
</p
>
10855 <p
>The goal is to be able to store the LTSP configuration attributes
10856 in a
"computer
" LDAP object used by both DNS and DHCP, and thus
10857 allowing us to store all information about a computer in one place.
</p
>
10859 <p
>This is a untested draft implementation, and I welcome feedback on
10860 this approach. A real LDAP schema for the ltspClientAux objectclass
10861 need to be written. Comments, suggestions, etc?

11048 <description><p
>For a laptop, centralized user directories and password checking is
11049 a bit troubling. Laptops are typically used also when not connected
11050 to the network, and it is vital for a user to be able to log in or
11051 unlock the screen saver also when a central server is unavailable.
11052 This is possible by caching passwords and directory information (user
11053 and group attributes) locally, and the packages to do so are available
11054 in Debian. Here follow two recipes to set this up in Debian/Squeeze.
11055 It is also possible to set up in Debian/Lenny, but require more manual
11056 setup there because pam-auth-update is missing in Lenny.
</p
>
11058 <h2
>LDAP/Kerberos + nscd + libpam-ccreds + libpam-mklocaluser/pam_mkhomedir
</h2
>
11060 This is the traditional method with a twist. The password caching is
11061 provided by libpam-ccreds (version
10-
4 or later is needed on
11062 Squeeze), and the directory caching is done by nscd. The directory
11063 lookup and password checking is done using LDAP. If one want to use
11064 Kerberos for password checking the libpam-ldapd package can be
11065 replaced with libpam-krb5 or libpam-heimdal. If one is happy having a
11066 local home directory with the path listed in LDAP, one can use the
11067 pam_mkhomedir module from pam-modules to make this happen instead of
11068 using libpam-mklocaluser. A setup for pam-auth-update to enable
11069 pam_mkhomedir will have to be written until a fix for
11070 <a href=
"http://bugs.debian.org/
568577">bug #
568577</a
> is in the
11071 archive. Because I believe it is a bad idea to have local home
11072 directories using misleading paths like /site/server/partition/, I
11073 prefer to create a local user with the home directory in /home/. This
11074 is done using the libpam-mklocaluser package.

11254 <description><p
>The last few days I have been looking into the status of the LDAP
11255 directory in Debian Edu, and in the process I started to miss a GUI
11256 tool to browse the LDAP tree. The only one I was able to find in
11257 Debian/Squeeze and Lenny is
11258 <a href=
"http://luma.sourceforge.net/
">LUMA
</a
>, which has proved to
11259 be a great tool to get a overview of the current LDAP directory
11260 populated by default in Skolelinux. Thanks to it, I have been able to
11261 find empty and obsolete subtrees, misplaced objects and duplicate
11262 objects. It will be installed by default in Debian/Squeeze. If you
11263 are working with LDAP, give it a go. :)
</p
>
11265 <p
>I did notice one problem with it I have not had time to report to
11266 the BTS yet. There is no .desktop file in the package, so the tool do
11267 not show up in the Gnome and KDE menus, but only deep down in in the
11268 Debian submenu in KDE. I hope that can be fixed before Squeeze is
11269 released.
</p
>
11271 <p
>I have not yet been able to get it to modify the tree yet. I would
11272 like to move objects and remove subtrees directly in the GUI, but have
11273 not found a way to do that with LUMA yet. So in the mean time, I use
11274 <a href=
"http://www.lichteblau.com/ldapvi/
">ldapvi
</a
> for that.
</p
>
11276 <p
>If you have tips on other GUI tools for LDAP that might be useful
11277 in Debian Edu, please contact us on debian-edu@lists.debian.org.

11279 <p

29: Ross Reedstrom tipped us about the
11280 <a href=
"http://packages.qa.debian.org/g/gq.html
">gq
</a
> package as a
11281 useful GUI alternative. It seem like a good tool, but is unmaintained
11282 in Debian and got a RC bug keeping it out of Squeeze. Unless that
11283 changes, it will not be an option for Debian Edu based on Squeeze.

11288 <title>Idea for a change to LDAP schemas allowing DNS and DHCP info to be combined into one object

>A while back, I
11293 <a href=
"http://people.skolelinux.org/pere/blog/Time_for_new__LDAP_schemas_replacing_RFC_2307_.html
">complained
11294 about the fact
</a

11295 for storing DNS and DHCP information in LDAP to combine the two sets
11296 of information into one LDAP object representing a computer.
</p
>
11298 <p
>In the mean time, I discovered that a simple fix would be to make
11299 the dhcpHost object class auxiliary, to allow it to be combined with
11300 the dNSDomain object class, and thus forming one object for one
11301 computer when storing both DHCP and DNS information in LDAP.
</p

11303 <p
>If I understand this correctly, it is not safe to do this change
11304 without also changing the assigned number for the object class, and I
11305 do not know enough about LDAP schema design to do that properly for
11306 Debian Edu.

11344 of Debian upgrades
</a

've
11345 finally made the upgrade logs available from
11346 <a href=
"http://people.skolelinux.org/pere/debian-upgrade-testing/
">http://people.skolelinux.org/pere/debian-upgrade-testing/
</a
>.
11347 I am now testing dist-upgrade of Gnome and KDE in a chroot using both
11348 apt and aptitude, and found their differences interesting. This time
11349 I will only focus on their removal plans.
</p
>
11351 <p
>After installing a Gnome desktop and the laptop task, apt-get wants
11352 to remove
72 packages when dist-upgrading from Lenny to Squeeze. The
11353 surprising part is that it want to remove xorg and all
11354 xserver-xorg-video* drivers. Clearly not a good choice, but I am not
11355 sure why. When asking aptitude to do the same, it want to remove
129
11356 packages, but most of them are library packages I suspect are no
11357 longer needed. Both of them want to remove bluetooth packages, which
11358 I do not know. Perhaps these bluetooth packages are obsolete?
</p
>
11360 <p
>For KDE, apt-get want to remove
82 packages, among them kdebase
11361 which seem like a bad idea and xorg the same way as with Gnome. Asking
11362 aptitude for the same, it wants to remove
192 packages, none which are
11363 too surprising.
</p
>
11365 <p
>I guess the removal of xorg during upgrades should be investigated
11366 and avoided, and perhaps others as well. Here are the complete list
11367 of planned removals. The complete logs is available from the URL
11368 above. Note if you want to repeat these tests, that the upgrade test
11369 for kde+apt-get hung in the tasksel setup because of dpkg asking
11370 conffile questions. No idea why. I worked around it by using
11371 '<tt
>echo
>> /proc/
<em
>pidofdpkg
</em
>/fd/
0</tt
>' to tell dpkg to
11372 continue.

11518 <description><p
>The last few days I have done some upgrade testing in Debian, to
11519 see if the upgrade from Lenny to Squeeze will go smoothly. A few bugs
11520 have been discovered and reported in the process
11521 (
<a href=
"http://bugs.debian.org/
585410">#
585410</a
> in nagios3-cgi,
11522 <a href=
"http://bugs.debian.org/
584879">#
584879</a
> already fixed in
11523 enscript and
<a href=
"http://bugs.debian.org/
584861">#
584861</a
> in
11524 kdebase-workspace-data), and to get a more regular testing going on, I
11525 am working on a script to automate the test.
</p
>
11527 <p
>The idea is to create a Lenny chroot and use tasksel to install a
11528 Gnome or KDE desktop installation inside the chroot before upgrading
11529 it. To ensure no services are started in the chroot, a policy-rc.d
11530 script is inserted. To make sure tasksel believe it is to install a
11531 desktop on a laptop, the tasksel tests are replaced in the chroot
11532 (only acceptable because this is a throw-away chroot).
</p
>
11534 <p
>A naive upgrade from Lenny to Squeeze using aptitude dist-upgrade
11535 currently always fail because udev refuses to upgrade with the kernel
11536 in Lenny, so to avoid that problem the file /etc/udev/kernel-upgrade
11537 is created. The bug report
11538 <a href=
"http://bugs.debian.org/
566000">#
566000</a
> make me suspect
11539 this problem do not trigger in a chroot, but I touch the file anyway
11540 to make sure the upgrade go well. Testing on virtual and real
11541 hardware have failed me because of udev so far, and creating this file
11542 do the trick in such settings anyway. This is a
11543 <a href=
"http://www.linuxquestions.org/questions/debian-
26/failed-dist-upgrade-due-to-udev-config_sysfs_deprecated-nonsense-
804130/
">known
11544 issue
</a
> and the current udev behaviour is intended by the udev
11545 maintainer because he lack the resources to rewrite udev to keep
11546 working with old kernels or something like that. I really wish the
11547 udev upstream would keep udev backwards compatible, to avoid such
11548 upgrade problem, but given that they fail to do so, I guess
11549 documenting the way out of this mess is the best option we got for
11550 Debian Squeeze.
</p
>
11552 <p
>Anyway, back to the task at hand, testing upgrades. This test
11553 script, which I call
<tt
>upgrade-test

>Som systemarkitekten bak Skolelinux, kan jeg bare riste på hodet
11676 over påstanden om at Skolelinux krever desentraliserte tjenere.
11677 Skolelinux-arkitekturen er laget for sentralisert drift og plassering
11678 av tjenerne lokalt eller sentralt alt etter behov og nettkapasitet.
11679 Den er modellert på nettverks- og tjenerløsningen som brukes på
11680 Universitetet i Tromsø og Oslo, der jeg jobber med utvikling av
11681 driftstjenester. Dette er det heldigvis noen som har fått med seg, og
11682 jeg er glad for å kunne sitere fra en kommentar på den overnevnte
11683 artikkelen. Min venn og gamle kollega Sturle Sunde forteller der:
11686 <p
>I Flora kommune køyrer vi Skulelinux på skular med alt frå
15 til
11687 meir enn
500 elevar. Dei store skulane har eigen tenar, for det er
11688 mest praktisk. Eg, som er driftsansvarleg for heile nettet, ser
11689 sjeldan dei tenarane fysisk, men at dei står der gjer skulane mindre
11690 avhengige av eksterne linjer som er trege eller dyre. Dei minste
11691 skulane har ikkje eigen tenar. Å bruke sentral tenar er heller ikkje
11692 noko problem. Småskulane klarar seg fint med
1 mbit-linje til ein
11693 sentral tenar eller tenaren på ein større skule.
</p
>
11695 <p
>Det beste med Skulelinux er halvtjukke klientar. Dei treng ikkje
11696 harddisk og brukar minimalt med ressursar på tenaren fordi dei køyrer
11697 programma lokalt. Eit klasserom med
30 sju-åtte år gamle maskiner har
11698 mykje meir CPU og RAM totalt enn nokon moderne tenar til under
11699 millionen. Det trengst to kommandoar på den sentrale tenaren for å
11700 oppdatere alle klientane, både tynne og halvtjukke. Vi har ingen
11701 problem med diskar som ryk heller, som var eit problem før fordi
11702 elevane sat og sparka i maskinene. Og dei krev lite bandbreidde i
11703 nettet, so det er fullt mogleg å køyre slike på småskular med trege
11704 linjer mot tenaren på ein større skule.
</p

11706 <p
>Flora kommune har nesten
800 Linux-maskiner i sitt skulenett, og
11707 ein person som tek seg av drift av heile nettet, inkludert tenarar,
11708 klientar, operativsystem, programvare, heimekontorløysing og
11709 administrasjon av brukarar.

>After a long break from debian-installer development, I finally
11863 found time today to return to the project. Having to spend less time
11864 working dependency based boot in debian, as it is almost complete now,
11865 definitely helped freeing some time.
</p
>
11867 <p
>A while back, I ran into a problem while working on Debian Edu. We
11868 include some firmware packages on the Debian Edu CDs, those needed to
11869 get disk and network controllers working. Without having these
11870 firmware packages available during installation, it is impossible to
11871 install Debian Edu on the given machine, and because our target group
11872 are non-technical people, asking them to provide firmware packages on
11873 an external medium is a support pain. Initially, I expected it to be
11874 enough to include the firmware packages on the CD to get
11875 debian-installer to find and use them. This proved to be wrong.
11876 Next, I hoped it was enough to symlink the relevant firmware packages
11877 to some useful location on the CD (tried /cdrom/ and
11878 /cdrom/firmware/). This also proved to not work, and at this point I
11879 found time to look at the debian-installer code to figure out what was
11880 going to work.
</p
>
11882 <p
>The firmware loading code is in the hw-detect package, and a closer
11883 look revealed that it would only look for firmware packages outside
11884 the installation media, so the CD was never checked for firmware
11885 packages. It would only check USB sticks, floppies and other
11886 "external
" media devices. Today I changed it to also look in the
11887 /cdrom/firmware/ directory on the mounted CD or DVD, which should
11888 solve the problem I ran into with Debian edu. I also changed it to
11889 look in /firmware/, to make sure the installer also find firmware
11890 provided in the initrd when booting the installer via PXE, to allow us
11891 to provide the same feature in the PXE setup included in Debian
11894 <p
>To make sure firmware deb packages with a license questions are not
11895 activated without asking if the license is accepted, I extended
11896 hw-detect to look for preinst scripts in the firmware packages, and
11897 run these before activating the firmware during installation. The
11898 license question is asked using debconf in the preinst, so this should
11899 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
11912 Edu finally entered the Debian archive. Today, the new
11913 <a href=
"http://packages.qa.debian.org/libp/libpam-mklocaluser.html
">libpam-mklocaluser
</a
>
11914 package was accepted. Two days ago, two other pieces was accepted
11916 <a href=
"http://packages.qa.debian.org/p/pam-python.html

11917 package needed by libpam-mklocaluser, and the
11918 <a href=
"http://packages.qa.debian.org/s/sssd.html
">sssd
</a

11919 passed NEW on Monday. In addition, the
11920 <a href=
"http://packages.qa.debian.org/libp/libpam-ccreds.html
">libpam-ccreds
</a
>
11921 package we need is in experimental (version
10-
4) since Saturday, and
11922 hopefully will be moved to unstable soon.
</p
>
11924 <p
>This collection of packages allow for two different setups for
11925 roaming laptops. The traditional setup would be using libpam-ccreds,
11926 nscd and libpam-mklocaluser with LDAP or Kerberos authentication,
11927 which should work out of the box if the configuration changes proposed
11928 for nscd in
<a href=
"http://bugs.debian.org/
485282">BTS report
11929 #
485282</a
> is implemented. The alternative setup is to use sssd with
11930 libpam-mklocaluser to connect to LDAP or Kerberos and let sssd take
11931 care of the caching of passwords and group information.
</p
>
11933 <p
>I have so far been unable to get sssd to work with the LDAP server
11934 at the University, but suspect the issue is some SSL/GnuTLS related
11935 problem with the server certificate. I plan to update the Debian
11936 package to version
1.2, which is scheduled for next week, and hope to
11937 find time to make sure the next release will include both the
11938 Debian/Ubuntu specific patches. Upstream is friendly and responsive,
11939 and I am sure we will find a good solution.
</p
>
11941 <p
>The idea is to set up the roaming laptops to authenticate using
11942 LDAP or Kerberos and create a local user with home directory in /home/
11943 when a usre in LDAP logs in via KDM or GDM for the first time, and
11944 cache the password for offline checking, as well as caching group
11945 memberhips and other relevant LDAP information. The
11946 libpam-mklocaluser package was created to make sure the local home
11947 directory is in /home/, instead of /site/server/directory/ which would
11948 be the home directory if pam_mkhomedir was used. To avoid confusion
11949 with support requests and configuration, we do not want local laptops
11950 to have users in a path that is used for the same users home directory
11951 on the home directory servers.
</p
>
11953 <p
>One annoying problem with gdm is that it do not show the PAM
11954 message passed to the user from libpam-mklocaluser when the local user
11955 is created. Instead gdm simply reject the login with some generic
11956 message. The message is shown in kdm, ssh and login, so I guess it is
11957 a bug in gdm. Have not investigated if there is some other message
11958 type that can be used instead to get gdm to also show the message.

12115 <description><p
>For some years now, I have wondered how we should handle laptops in
12116 Debian Edu. The Debian Edu infrastructure is mostly designed to
12117 handle stationary computers, and less suited for computers that come
12120 <p
>Now I finally believe I have an sensible idea on how to adjust
12121 Debian Edu for laptops, by introducing a new profile for them, for
12122 example called Roaming Workstations. Here are my thought on this.
12123 The setup would consist of the following:
</p
>
12127 <li
>During installation, the user name of the owner / primary user of
12128 the laptop is requested and a local home directory is set up for
12129 the user, with uid and gid information fetched from the LDAP
12130 server. This allow the user to work also when offline. The
12131 central home directory can be available in a subdirectory on
12132 request, for example mounted via CIFS. It could be mounted
12133 automatically when a user log in while on the Debian Edu network,
12134 and unmounted when the machine is taken away (network down,
12135 hibernate, etc), it can be set up to do automatic mounting on
12136 request (using autofs), or perhaps some GUI button on the desktop
12137 can be used to access it when needed. Perhaps it is enough to use
12138 the fish protocol in KDE?
</li
>
12140 <li
>Password checking is set up to use LDAP or Kerberos
12141 authentication when the machine is on the Debian Edu network, and
12142 to cache the password for offline checking when the machine unable
12143 to reach the LDAP or Kerberos server. This can be done using
12144 <a href=
"http://www.padl.com/OSS/pam_ccreds.html
">libpam-ccreds
</a
>
12145 or the Fedora developed
12146 <a href=
"https://fedoraproject.org/wiki/Features/SSSD
">System
12147 Security Services Daemon
</a
> packages.
</li
>
12149 <li
>File synchronisation with the central home directory is set up
12150 using a shared directory in both the local and the central home
12151 directory, using unison.
</li
>
12153 <li
>Printing should be set up to print to all printers broadcasting
12154 their existence on the local network, and should then work out of
12155 the box with CUPS. For sites needing accurate printer quotas, some
12156 system with Kerberos authentication or printing via ssh could be
12157 implemented.
</li
>
12159 <li
>For users that should have local root access to their laptop,
12160 sudo should be used to allow this to the local user.
</li
>
12162 <li
>It would be nice if user and group information from LDAP is
12163 cached on the client, but given that there are entries for the
12164 local user and primary group in /etc/, it should not be needed.
</li
>
12168 <p
>I believe all the pieces to implement this are in Debian/testing at
12169 the moment. If we work quickly, we should be able to get this ready
12170 in time for the Squeeze release to freeze. Some of the pieces need
12171 tweaking, like libpam-ccreds should get support for pam-auth-update
12172 (
<a href=
"http://bugs.debian.org/
566718">#
566718</a
>) and nslcd (or
12173 perhaps debian-edu-config) should get some integration code to stop
12174 its daemon when the LDAP server is unavailable to avoid long timeouts
12175 when disconnected from the net. If we get Kerberos enabled, we need
12176 to make sure we avoid long timeouts there too.

12189 NUUG presentation
</a
> about Kerberos was inspiring, and reminded me
12190 about the need to start using Kerberos in Skolelinux. Setting up a
12191 Kerberos server seem to be straight forward, and if we get this in
12192 place a long time before the Squeeze version of Debian freezes, we
12193 have a chance to migrate Skolelinux away from NFSv3 for the home
12194 directories, and over to an architecture where the infrastructure do
12195 not have to trust IP addresses and machines, and instead can trust
12196 users and cryptographic keys instead.
</p
>
12198 <p
>A challenge will be integration and administration. Is there a
12199 Kerberos implementation for Debian where one can control the
12200 administration access in Kerberos using LDAP groups? With it, the
12201 school administration will have to maintain access control using flat
12202 files on the main server, which give a huge potential for errors.
</p
>
12204 <p
>A related question I would like to know is how well Kerberos and
12205 pam-ccreds (offline password check) work together. Anyone know?
</p
>
12207 <p
>Next step will be to use Kerberos for access control in Lwat and
12208 Nagios. I have no idea how much work that will be to implement. We
12209 would also need to document how to integrate with Windows AD, as such
12210 shared network will require two Kerberos realms that need to cooperate
12211 to work properly.
</p
>
12213 <p
>I believe a good start would be to start using Kerberos on the
12214 skolelinux.no machines, and this way get ourselves experience with
12215 configuration and integration. A natural starting point would be
12216 setting up ldap.skolelinux.no as the Kerberos server, and migrate the
12217 rest of the machines from PAM via LDAP to PAM via Kerberos one at the
12220 <p
>If you would like to contribute to get this working in Skolelinux,
12221 I recommend you to see the video recording from yesterdays NUUG
12222 presentation, and start using Kerberos at home. The video show show
12223 up in a few days.

>6 years ago, as part of the Debian Edu development I am involved
12233 in, I asked for a hook in the kdm and gdm setup to run scripts as root

12235 package in
2004 (
<a href=

230422</a

12236 and revisited every time Debian Edu was working on a new release.
12237 Today, this finally paid off.

12239 <p
>The framework for this feature was today commited to the git
12240 repositry for the xorg package, and the git repository for xdm has
12241 been updated to use this framework. Next on my agenda is to make sure
12242 kdm and gdm also add code to use this framework.
</p

12244 <p
>In Debian Edu, we want to ability to run commands as root when the
12245 user log out, to get rid of runaway processes and do general cleanup
12246 after a user. With this framework in place, we finally can do that in
12247 a generic way that work with all display managers using this
12248 framework. My goal is to get all display managers in Debian use it,
12249 similar to how they use the Xsession.d framework today.

>One of the new features in the next Debian/Lenny based release of
12281 Debian Edu/Skolelinux, which is scheduled for release in the next few
12282 days, is automatic configuration of the service monitoring system
12283 Nagios. The previous release had automatic configuration of trend
12284 analysis using Munin, and this Lenny based release take that a step
12287 <p
>When installing a Debian Edu Main-server, it is automatically
12288 configured as a Munin and Nagios server. In addition, it is
12289 configured to be a server for the
12290 <a href=
"http://wiki.debian.org/DebianEdu/HowTo/SiteSummary
">SiteSummary
12291 system
</a
> I have written for use in Debian Edu. The SiteSummary
12292 system is inspired by a system used by the University of Oslo where I
12293 work. In short, the system provide a centralised collector of
12294 information about the computers on the network, and a client on each
12295 computer submitting information to this collector. This allow for
12296 automatic information on which packages are installed on each machine,
12297 which kernel the machines are using, what kind of configuration the
12298 packages got etc. This also allow us to automatically generate Munin
12299 and Nagios configuration.
</p
>
12301 <p
>All computers reporting to the sitesummary collector with the
12302 munin-node package installed is automatically enabled as a Munin
12303 client and graphs from the statistics collected from that machine show
12304 up automatically on http://www/munin/ on the Main-server.
</p
>
12306 <p
>All non-laptop computers reporting to the sitesummary collector are
12307 automatically monitored for network presence (ping and any network
12308 services detected). In addition, all computers (also laptops) with
12309 the nagios-nrpe-server package installed and configured the way
12310 sitesummary would configure it, are monitored for full disks, software
12311 raid status, swap free and other checks that need to run locally on
12312 the machine.
</p
>
12314 <p
>The result is that the administrator on a school using Debian Edu
12315 based on Lenny will be able to check the health of his installation
12316 with one look at the Nagios settings, without having to spend any time
12317 keeping the Nagios configuration up-to-date.
</p
>
12319 <p
>The only configuration one need to do to get Nagios up and running
12320 is to set the password used to get access via HTTP. The system
12321 administrator need to run
"<tt
>htpasswd /etc/nagios3/htpasswd.users
12322 nagiosadmin
</tt
>" to create a nagiosadmin user and set a password for
12323 it to be able to log into the Nagios web pages. After that,
12324 everything is taken care of.

12349 Etter demonstrasjonen arrangerte Håkon en fest hjemme hos seg der alle
12350 som hadde vært aktive i demonstrasjonsplanlegging og gjennomføringen
12351 deltok. Før festen var jeg blitt lei av å vente på at Håkon skulle ta
12352 initiativ til

12353 besteme jeg meg for å benytte anledningen hos Håkon til å snakke om
12354 behovet for å hjelpe skolene i gang med bedre datasystemer bestående
12355 av fri programvare og unix-lignende operativsystemer. Flere var
12356 interessert, og Knut Yrvin tenkte på ideen. Han

'm sitting on the train going home from this weekends Debian
12394 Edu/Skolelinux development gathering. I got a bit done tuning the
12395 desktop, and looked into the dynamic service location protocol
12396 implementation avahi. It look like it could be useful for us. Almost
12397 30 people participated, and I believe it was a great environment to
12398 get to know the Skolelinux system. Walter Bender, involved in the
12399 development of the Sugar educational platform, presented his stuff and
12400 also helped me improve my OLPC installation. He also showed me that
12401 his Turtle Art application can be used in standalone mode, and we
12402 agreed that I would help getting it packaged for Debian. As a
12403 standalone application it would be great for Debian Edu. We also
12404 tried to get the video conferencing working with two OLPCs, but that
12405 proved to be too hard for us. The application seem to need more work
12406 before it is ready for me. I look forward to getting home and relax

>The state of standardized LDAP schemas on Linux is far from
12417 optimal. There is RFC
2307 documenting one way to store NIS maps in
12418 LDAP, and a modified version of this normally called RFC
2307bis, with
12419 some modifications to be compatible with Active Directory. The RFC
12420 specification handle the content of a lot of system databases, but do
12421 not handle DNS zones and DHCP configuration.

12424 we would like to store information about users, SMB clients/hosts,
12425 filegroups, netgroups (users and hosts), DHCP and DNS configuration,
12426 and LTSP configuration in LDAP. These objects have a lot in common,
12427 but with the current LDAP schemas it is not possible to have one
12428 object per entity. For example, one need to have at least three LDAP
12429 objects for a given computer, one with the SMB related stuff, one with
12430 DNS information and another with DHCP information. The schemas
12431 provided for DNS and DHCP are impossible to combine into one LDAP
12432 object. In addition, it is impossible to implement quick queries for
12433 netgroup membership, because of the way NIS triples are implemented.
12434 It just do not scale. I believe it is time for a few RFC
12435 specifications to cleam up this mess.

</a

12479 endelig første juledag. Bruken av bindestrek som ordskillemarkør har
12480 gjort det umulig å få med ord med bindestrek i
12481 stavekontrolldatagrunnlaget, slik at ord som e-post og CD-spiller ikke
12482 kunne godtas av stavekontrollen. Hadde litt tid til overs å bruke på
12483 stavekontrollen, og satte meg ned med to kopier av byggsystemet og en
12484 liten testdatafil, og byttet ut - med = på utvalgte steder i
12485 byggsystemet og datafilen helt til jeg fikk samme resultat med det
12486 gamle og det nye byggsystemet. Dette tror jeg var forsøk
4, der de
12487 foregående har feilet uten at jeg klarte å forstå hvorfor. Det sier
12488 kanskje litt om kompleksiteten i det originale byggsystemet som Rune
12489 Kleveland laget i sin tid.

12511 Acer Aspire One proved to be a very nice thin client, with both

>Recently I have spent some time evaluating the multimedia browser
12530 plugins available in Debian Lenny, to see which one we should use by
12531 default in Debian Edu. We need an embedded video playing plugin with
12532 control buttons to pause or stop the video, and capable of streaming
12533 all the multimedia content available on the web. The test results and
12534 notes are available on
12535 <a href=
"http://wiki.debian.org/DebianEdu/BrowserMultimedia
">the
12536 Debian wiki
</a
>. I was surprised how few of the plugins are able to
12537 fill this need. My personal video player favorite, VLC, has a really
12538 bad plugin which fail on a lot of the test pages. A lot of the MIME
12539 types I would expect to work with any free software player (like
12540 video/ogg), just do not work. And simple formats like the
12541 audio/x-mplegurl format (m3u playlists), just isn
't supported by the
12542 totem and vlc plugins. I hope the situation will improve soon. No
12543 wonder sites use the proprietary Adobe flash to play video.
