48 imply, public domain and permissively licensed software can lead to
49 the production of more proprietary software as people discover useful
50 software, extend it and or incorporate it into their hardware or
51 software products. Copyleft licenses such as the GNU GPL were created
52 to close off this avenue to the production of proprietary software but
53 such licenses are not enough. With the ongoing adoption of Free
54 Software by individuals and groups, inevitably the community
's
55 expectations of license compliance are violated, usually out of
56 ignorance of the way Free Software works, but not always. As Karen

"Jessie
" 8.0+edu0~b1, which for the first
130 time is composed entirely of packages from the current Debian stable
131 release, Debian
8 "Jessie
".
133 (As most reading this will know, Debian
"Jessie
" hasn
't actually been
134 released by now. The release is still in progress but should finish
137 We expect to make a final release of Debian Edu
"Jessie
" in the coming
138 weeks, timed with the first point release of Debian Jessie. Upgrades
139 from this beta release of Debian Edu Jessie to the final release will
140 be possible and encouraged!
142 Please report feedback to debian-edu@lists.debian.org and/or submit
143 bugs: http://wiki.debian.org/DebianEdu/HowTo/ReportBugs
145 Debian Edu - sometimes also known as
"Skolelinux
" - is a complete
146 operating system for schools, universities and other
147 organisations. Through its pre- prepared installation profiles
148 administrators can install servers, workstations and laptops which
149 will work in harmony on the school network. With Debian Edu, the
150 teachers themselves or their technical support staff can roll out a
151 complete multi-user, multi-machine study environment within hours or
154 Debian Edu is already in use at several hundred schools all over the
155 world, particularly in Germany, Spain and Norway. Installations come
156 with hundreds of applications pre-installed, plus the whole Debian
157 archive of thousands of compatible packages within easy reach.
159 For those who want to give Debian Edu Jessie a try, download and
160 installation instructions are available, including detailed

272 == About Debian Edu / Skolelinux ==
274 Debian Edu, also known as Skolelinux, is a Linux distribution based on
275 Debian providing an out-of-the box environment of a completely
276 configured school network. Directly after installation a school server
277 running all services needed for a school network is set up just
278 waiting for users and machines being added via GOsa², a comfortable
279 Web-UI. A netbooting environment is prepared using PXE, so after
280 initial installation of the main server from CD or USB stick all other
281 machines can be installed via the network. The provided school server
282 provides LDAP database and Kerberos authentication service,
283 centralized home directories, DHCP server, web proxy and many other
284 services. The desktop contains more than
60 educational software
285 packages and more are available from the Debian archive, and schools
286 can choose between KDE, GNOME, LXDE, Xfce and MATE desktop
291 The Debian Project was founded in
1993 by Ian Murdock to be a truly
292 free community project. Since then the project has grown to be one of
293 the largest and most influential open source projects. Thousands of
294 volunteers from all over the world work together to create and
295 maintain Debian software. Available in
70 languages, and supporting a
296 huge range of computer types, Debian calls itself the universal
301 Thanks to everyone making Debian and Debian Edu / Skolelinux happen!

>It was a surprise to me to learn that project to create a complete
313 computer system for schools I
've involved in,
314 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>, was
315 being used in India. But apparently it is, and I managed to get an
316 interview with one of the friends of the project there, Shirish
319 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
321 <p
>My name is Shirish Agarwal. Based out of the educational and
322 historical city of Pune, from the western state of Maharashtra, India.
323 My bread comes from giving training, giving policy tips,
324 installations on free software to mom and pop shops in different
325 fields from Desktop publishing to retail shops as well as work with
326 few software start-ups as well.
</p
>
328 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
329 project?
</strong
></p
>
331 <p
>It started innocently enough. I have been using Debian for a few
332 years and in one local minidebconf / debutsav I was asked if there was
333 anything for schools or education. I had worked / played with free
334 educational softwares such as Gcompris and Stellarium for my many
335 nieces and nephews so researched and found Debian Edu or Skolelinux as
336 it was known then. Since then I have started using the various
337 education meta-packages provided by the project.
</p
>
339 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
340 Edu?
</strong
></p
>
342 <p
>It
's closest I have seen where a package full of educational
343 software are packed, which are free and open (both literally and
344 figuratively). Even if I take the simplest software which is
345 gcompris, the number of activities therein are amazing. Another one of
346 the softwares that I have liked for a long time is stellarium. Even
347 pysycache is cool except for couple of issues I encountered
348 <a href=
"https://bugs.debian.org/
781841">#
781841</a
> and
349 <a href=
"https://bugs.debian.org/
781842">#
781842</a
>.
</p
>
351 <p
>I prefer software installed on the system over web based solutions,
352 as a web site can disappear any time but the software on disk has the
353 possibility of a larger life span. Of course with both it
's more a
354 question if it has enough users who make it fun or sustainable or both
355 for the developer per-se.
</p
>
357 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
358 Edu?
</strong
></p
>
360 <p
>I do see that the Debian Edu team seems to be short-handed and I
361 think more efforts should be made to make it popular and ask and take
362 help from people and the larger community wherever possible.
</p
>
364 <p
>I don
't see any disadvantage to use Skolelinux apart from the fact
365 that most apps. are generic which is good or bad how you see it.
366 However, saying that I do acknowledge the fact that the canvas is
367 pretty big and there are lot of interesting ideas that could be done
368 but for reasons not known not done or if done I don
't know about them.
369 Let me share some of the ideas (these are more upstream based but
370 still) I have had for a long time :
</p
>
372 <p
>1. Classical maths question of two trains in opposing directions
373 each running @x kmph/mph at y distance, when they will meet and how
374 far would each travel and similar questions like these.
376 <p
>The computer is a fantastic system where questions like these can
377 be drawn, animated and the methodology and answers teased out in
378 interactive manner. While sites such as the
379 <a href=
"http://mathforum.org/dr.math/faq/faq.two.trains.html
">Ask
380 Dr. Math FAQ on The Two Trains problem
</a
> (as an example or point of
381 inspiration) can be used there is lot more that can be done. I dunno
382 if there is a free software which does something like this. The idea
383 being a blend of objects + animation + interaction which does
384 this. The whole interaction could be gamified with points or sounds or
385 colourful celebration whenever the user gets even part of the question
386 or/and methodology right. That would help reinforce good behaviour.
387 This understanding could be used to share/showcase everything from how
388 the first wheel came to be, to evolution to how astronomy started,
389 psychics and everything in-between.
</p
>
391 <p
>One specific idea in the train part was having the Linux mascot on
392 one train and the BSD or GNU mascot on the other train and they
393 meeting somewhere in-between. Characters from blender movies could
394 also be used.
</p
>
396 <p
>2. Loads of crossword-puzzles with reference to subjects: We have
397 enormous data sets in Wikipedia and Wikitionary. I don
't think it
398 should be a big job to design crossword puzzles. Using categories and
399 sub-categories it should be doable to have Q
&A single word answers
400 from the existing data-sets. What would make it easy or hard could be
401 the length of the word + existence of many or few vowels depending on
402 the user
's input.
</p
>
404 <p
>3. Jigsaw puzzles - We already have a great software called
405 palapeli with number of slicers making it pretty interesting. What
406 needs to be done is to download large number of public domain and
407 copyleft images, tease and use IPTC tags to categorise them into
408 nature, history etc. and let it loose. This could turn to be really
409 huge collection of images. One source could be taken from
410 commons.wikimedia.org, others could be huge collection of royalty-free
411 stock photos. Potential is immense.
</p
>
413 <p
>Apart from this, free software suffers in two directions, we lag
414 both in development (of using new features per-se) and maintenance a
415 lot. This is more so in educational software as these applications
416 need to be timely and the opportunity cost of missing deadlines is
417 immense. If we are able to solve issues of funding for development and
418 maintenance of such software I don
't see any big difficulties. I know
419 of few start-ups in and around India who would love to develop and
420 maintain such software if funding issues could be solved.
</p
>
422 <p
><strong
>Which free software do you use daily?
</strong
></p
>
424 <p
>That would be huge list. Some of the softwares are obviously apt,
425 aptitude, debdelta, leafpad, the shell of course (zsh nowadays),
426 quassel for IRC. In games I use shisen-sho while card-games are evenly
427 between kpat and Aiselriot. In desktops it
's a tie between
428 gnome-flashback and mate.
</p
>
430 <p
><strong
>Which strategy do you believe is the right one to use to
431 get schools to use free software?
</strong
></p
>
433 <p
>I think it should first start with using specific FOSS apps. in
434 whatever environment they are. If it
's MS-Windows or Mac so be it.
435 Once they are habitual with the apps. and there is buy-in from the
436 school management then it could be installed anywhere. Most of the
437 people now understand the concept of a repository because of the
438 various online stores so it isn
't hard to convince on that front.
</p
>
440 <p
>What is harder is having enough people with technical skills and
441 passion to service them. If you get buy-in from one or two teachers
442 then ideas like above could also be asked to be done as a project as
445 <p
>I think where we fall short more than anything is in marketing. For
446 instance, Debian has this whole range of fonts in its archive but
447 there isn
't even a page where all those different fonts in the La
448 Ipsum format could be tried out for newcomers.
</p
>
450 <p
>One of the issues faced constantly in installations is with updates
451 and upgrades. People have this myth that each update and upgrade
452 means the user interface will / has to change. I have seen this
453 innumerable times. That perhaps is one of the reasons which browsers
454 like Iceweasel / Firefox change user interfaces so much, not because
455 it might be needed or be functional but because people believe that

506 The Debian Edu Team is pleased to announce the release of Debian Edu
507 Jessie
8.0+edu0~alpha0
509 Debian Edu is a complete operating system for schools. Through its
510 various installation profiles you can install servers, workstations
511 and laptops which will work together on the school network. With
512 Debian Edu, the teachers themselves or their technical support can
513 roll out a complete multi-user multi-machine study environment within
514 hours or a few days. Debian Edu comes with hundreds of applications
515 pre-installed, but you can always add more packages from Debian.
517 For those who want to give Debian Edu Jessie a try, download and
518 installation instructions are available, including detailed
519 instructions in the manual[
1] explaining the first steps, such as
520 setting up a network or adding users. Please note that the password
521 for the user your prompted for during installation must have a length
522 of at least
5 characters!

526 Would you like to give your school
's computer a longer life? Are you
527 tired of sneaker administration, running from computer to computer
528 reinstalling the operating system? Would you like to administrate all
529 the computers in your school using only a couple of hours every week?
530 Check out Debian Edu Jessie!
532 Skolelinux is used by at least two hundred schools all over the world,
533 mostly in Germany and Norway.
535 About Debian Edu and Skolelinux
536 ===============================
538 Debian Edu, also known as Skolelinux[
2], is a Linux distribution based
539 on Debian providing an out-of-the box environment of a completely
540 configured school network. Immediately after installation a school
541 server running all services needed for a school network is set up just
542 waiting for users and machines being added via GOsa², a comfortable
543 Web-UI. A netbooting environment is prepared using PXE, so after
544 initial installation of the main server from CD or USB stick all other
545 machines can be installed via the network. The provided school server
546 provides LDAP database and Kerberos authentication service,
547 centralized home directories, DHCP server, web proxy and many other
548 services. The desktop contains more than
60 educational software
549 packages[
3] and more are available from the Debian archive, and
550 schools can choose between KDE, Gnome, LXDE, Xfce and MATE desktop

692 Edu on machines with disk (and a few other services perhaps to small
693 to mention here). We in the Debian Edu team are currently working on
694 the Jessie based version, trying to get everything in shape before the
695 freeze, to avoid having to maintain our own package repository in the
697 <a href=
"https://wiki.debian.org/DebianEdu/Status/Jessie

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

">http
</a
>
707 ftp.skolelinux.org::cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-
1.iso).
708 The ISO build was broken on Tuesday, so we do not get a new ISO every
709 12 hours or so, but thankfully the ISO we already got we are able to
710 install with some tweaking.
</p
>
712 <p
>When you get to the Debian Edu profile question, go to tty2
713 (use Alt-Ctrl-F2), run
</p
>
715 <p
><blockquote
><pre
>
716 nano /usr/bin/edu-eatmydata-install
717 </pre
></blockquote
></p
>
719 <p
>and add
'exit
0' as the second line, disabling the eatmydata
720 optimization. Return to the installation, select the profile you want
721 and continue. Without this change, exim4-config will fail to install
722 due to a known bug in eatmydata.
</p
>
724 <p
>When you get the grub question at the end, answer /dev/sda (or if
725 this do not work, figure out what your correct value would be. All my
726 test machines need /dev/sda, so I have no advice if it do not fit
729 <p
>If you installed a profile including a graphical desktop, log in as
730 root after the initial boot from hard drive, and install the
731 education-desktop-XXX metapackage. XXX can be kde, gnome, lxde, xfce
732 or mate. If you want several desktop options, install more than one
733 metapackage. Once this is done, reboot and you should have a working
734 graphical login screen. This workaround should no longer be needed
735 once the education-tasks package version
1.801 enter testing in two
738 <p
>I believe the ISO build will start working on two days when the new
739 tasksel package enter testing and Steve McIntyre get a chance to
740 update the debian-cd git repository. The eatmydata, grub and desktop
741 issues are already fixed in unstable and testing, and should show up
742 on the ISO as soon as the ISO build start working again. Well the
743 eatmydata optimization is really just disabled. The proper fix
744 require an upload by the eatmydata maintainer applying the patch
745 provided in bug
<a href=
"https://bugs.debian.org/
702711">#
702711</a
>.
746 The rest have proper fixes in unstable.
</p
>
748 <p
>I hope this get you going with the installation testing, as we are
749 quickly running out of time trying to get our Jessie based
750 installation ready before the distribution freeze in a month.

<a href=

760 a lot quicker. When we install more than
2000 packages in
761 <a href=
"http://www.skolelinux.org/
">Skolelinux / Debian Edu
</a
> using
762 tasksel in the installer, unpacking the binary packages take forever.
763 A part of the slow I/O issue was discussed in
764 <a href=
"https://bugs.debian.org/
613428">bug #
613428</a
> about too
765 much file system sync-ing done by dpkg, which is the package
766 responsible for unpacking the binary packages. Other parts (like code
767 executed by postinst scripts) might also sync to disk during
768 installation. All this sync-ing to disk do not really make sense to
769 me. If the machine crash half-way through, I start over, I do not try
770 to salvage the half installed system. So the failure sync-ing is
771 supposed to protect against, hardware or system crash, is not really
772 relevant while the installer is running.
</p
>
774 <p
>A few days ago, I thought of a way to get rid of all the file
775 system sync()-ing in a fairly non-intrusive way, without the need to
776 change the code in several packages. The idea is not new, but I have
777 not heard anyone propose the approach using dpkg-divert before. It
778 depend on the small and clever package
779 <a href=
"https://packages.qa.debian.org/eatmydata
">eatmydata
</a
>, which
780 uses LD_PRELOAD to replace the system functions for syncing data to
781 disk with functions doing nothing, thus allowing programs to live
782 dangerous while speeding up disk I/O significantly. Instead of
783 modifying the implementation of dpkg, apt and tasksel (which are the
784 packages responsible for selecting, fetching and installing packages),
785 it occurred to me that we could just divert the programs away, replace
786 them with a simple shell wrapper calling
787 "eatmydata
&nbsp;$program
&nbsp;$@
", to get the same effect.
788 Two days ago I decided to test the idea, and wrapped up a simple
789 implementation for the Debian Edu udeb.
</p
>
791 <p
>The effect was stunning. In my first test it reduced the running
792 time of the pkgsel step (installing tasks) from
64 to less than
44
793 minutes (
20 minutes shaved off the installation) on an old Dell
794 Latitude D505 machine. I am not quite sure what the optimised time
795 would have been, as I messed up the testing a bit, causing the debconf
796 priority to get low enough for two questions to pop up during
797 installation. As soon as I saw the questions I moved the installation
798 along, but do not know how long the question were holding up the
799 installation. I did some more measurements using Debian Edu Jessie,
800 and got these results. The time measured is the time stamp in
801 /var/log/syslog between the
"pkgsel: starting tasksel
" and the
802 "pkgsel: finishing up
" lines, if you want to do the same measurement
803 yourself. In Debian Edu, the tasksel dialog do not show up, and the
804 timing thus do not depend on how quickly the user handle the tasksel

>The test is done using a netinst ISO on a USB stick, so some of the
854 time is spent downloading packages. The connection to the Internet
855 was
100Mbit/s during testing, so downloading should not be a
856 significant factor in the measurement. Download typically took a few
857 seconds to a few minutes, depending on the amount of packages being
860 <p
>The speedup is implemented by using two hooks in
861 <a href=
"https://www.debian.org/devel/debian-installer/
">Debian
862 Installer
</a
>, the pre-pkgsel.d hook to set up the diverts, and the
863 finish-install.d hook to remove the divert at the end of the
864 installation. I picked the pre-pkgsel.d hook instead of the
865 post-base-installer.d hook because I test using an ISO without the
866 eatmydata package included, and the post-base-installer.d hook in
867 Debian Edu can only operate on packages included in the ISO. The
868 negative effect of this is that I am unable to activate this
869 optimization for the kernel installation step in d-i. If the code is
870 moved to the post-base-installer.d hook, the speedup would be larger
871 for the entire installation.

've implemented this in the

876 Debian Edu installation. If you want to test this yourself, you can
877 create two files in the installer (or in an udeb). One shell script
878 need do go into /usr/lib/pre-pkgsel.d/, with content like this:

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

990 <p
>My name is Bernd Zeitzen and I
'm married with Hedda, a self
991 employed physiotherapist. My former profession is tool maker, but I
992 haven
't worked for
30 years in this job.
30 years ago I started to
993 support my wife and become her officeworker and a few years later the
994 administrator for a small computer network, today based on Ubuntu
995 Server (Samba, OpenVPN). For her daily work she has to use Windows
996 Desktops because the software she needs to organize her business only
997 works with Windows . :-(
</p
>
999 <p
>In
1988 we started with one PC and DOS, then I learned to use
1000 Windows
98,
2000, XP, …,
8, Ubuntu, MacOSX. Today we are running a
1001 Linux server with
6 Windows clients and
10 persons (teacher of
1002 children with special needs, speech therapist, occupational therapist,
1003 psychologist and officeworkers) using our Samba shares via OpenVPN to
1004 work with the documentations of our patients.

1006 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
1007 project?
</strong
></p

1009 <p
>Two years ago a friend of mine asked me, if I want to get a job in
1010 his school (
<a href=
"http://www.gymnasium-harsewinkel.de/
">Gymnasium
1011 Harsewinkel
</a
>). They started with Skolelinux / Debian Edu and they
1012 were looking for people to give support to the teachers using the
1013 software and the network and teaching the pupils increasing their
1014 computer skills in optional lessons. I
'm spending
4-
6 hours a week
1015 with this job.

1017 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
1018 Edu?
</strong
></p
>
1020 <p
>The independence.
</p
>
1022 <p
>First: Every person is allowed to use, share and develop the
1023 software. Even if you are poor, you are allowed to use the software
1024 included in Skolelinux/Debian Edu and all the other Free Software.
</p
>
1026 <p
>Second: The software runs on old machines and this gives us the
1027 possibility to recycle computers, weeded out from offices. The
1028 servers and desktops are running for more than two years and they are
1029 working reliable.
</p
>
1031 <p
>We have two servers (one tjener and one terminal server),
45
1032 workstations in three classrooms and seven laptops as a mobile
1033 solution for all classrooms. These machines are all booting from the
1034 terminal server. In the moment we are installing
30 laptops as mobile
1035 workstations. Then the pupils have the possibility to work with these
1036 machines in their classrooms. Internet access is realized by a WLAN
1037 router, connected to the schools network. This is all done without a
1038 dedicated system administrator or a computer science teacher.

1043 <p
>Teachers and pupils are Windows users.
&lt;Irony on
&gt; And Linux
1044 isn
't cool. It
's software for freaks using the command line.
&lt;Irony
1045 off
&gt; They don
't realize the stability of the system.
</p

1047 <p
><strong
>Which free software do you use daily?
</strong

1049 <p
>Firefox, Thunderbird, LibreOffice, Ubuntu Server
12.04 (Samba,
1050 Apache, MySQL, Joomla!, … and Skolelinux / Debian Edu)
</p

1052 <p
><strong
>Which strategy do you believe is the right one to use to
1053 get schools to use free software?
</strong
></p
>
1055 <p
>In Germany we have the situation: every school is free to decide
1056 which software they want to use. This decision is influenced by
1057 teachers who learned to use Windows and MS Office. They buy a PC with
1058 Windows preinstalled and an additional testing version of MS
1059 Office. They don
't know about the possibility to use Free Software
1060 instead. Another problem are the publisher of school books. They
1061 develop their software, added to the school books, for Windows.

>The
<a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
1071 project
</a
> provide an instruction manual for teachers, system
1072 administrators and other users that contain useful tips for setting up
1073 and maintaining a Debian Edu installation. This text is about how the
1074 text processing of this manual is handled in the project.
</p
>
1076 <p
>One goal of the project is to provide information in the native
1077 language of its users, and for this we need to handle translations.
1078 But we also want to make sure each language contain the same
1079 information, so for this we need a good way to keep the translations
1080 in sync. And we want it to be easy for our users to improve the
1081 documentation, avoiding the need to learn special formats or tools to
1082 contribute, and the obvious way to do this is to make it possible to
1083 edit the documentation using a web browser. We also want it to be
1084 easy for translators to keep the translation up to date, and give them
1085 help in figuring out what need to be translated. Here is the list of
1086 tools and the process we have found trying to reach all these
1089 <p
>We maintain the authoritative source of our manual in the
1090 <a href=
"https://wiki.debian.org/DebianEdu/Documentation/Wheezy/
">Debian
1091 wiki
</a
>, as several wiki pages written in English. It consist of one
1092 front page with references to the different chapters, several pages
1093 for each chapter, and finally one
"collection page
" gluing all the
1094 chapters together into one large web page (aka
1095 <a href=
"https://wiki.debian.org/DebianEdu/Documentation/Wheezy/AllInOne
">the
1096 AllInOne page
</a
>). The AllInOne page is the one used for further
1097 processing and translations. Thanks to the fact that the
1098 <a href=
"http://moinmo.in/
">MoinMoin
</a
> installation on
1099 wiki.debian.org support exporting pages in
1100 <a href=
"http://www.docbook.org/
">the Docbook format
</a
>, we can fetch
1101 the list of pages to export using the raw version of the AllInOne
1102 page, loop over each of them to generate a Docbook XML version of the
1103 manual. This process also download images and transform image
1104 references to use the locally downloaded images. The generated
1105 Docbook XML files are slightly broken, so some post-processing is done
1106 using the
<tt
>documentation/scripts/get_manual
</tt
> program, and the
1107 result is a nice Docbook XML file (debian-edu-wheezy-manual.xml) and
1108 a handfull of images. The XML file can now be used to generate PDF, HTML
1109 and epub versions of the English manual. This is the basic step of
1110 our process, making PDF (using dblatex), HTML (using xsltproc) and
1111 epub (using dbtoepub) version from Docbook XML, and the resulting files
1112 are placed in the debian-edu-doc-en binary package.
</p
>
1114 <p
>But English documentation is not enough for us. We want translated
1115 documentation too, and we want to make it easy for translators to
1116 track the English original. For this we use the
1117 <a href=
"http://packages.qa.debian.org/p/poxml.html
">poxml
</a
> package,
1118 which allow us to transform the English Docbook XML file into a
1119 translation file (a .pot file), usable with the normal gettext based
1120 translation tools used by those translating free software. The pot
1121 file is used to create and maintain translation files (several .po
1122 files), which the translations update with the native language
1123 translations of all titles, paragraphs and blocks of text in the
1124 original. The next step is combining the original English Docbook XML
1125 and the translation file (say debian-edu-wheezy-manual.nb.po), to
1126 create a translated Docbook XML file (in this case
1127 debian-edu-wheezy-manual.nb.xml). This translated (or partly
1128 translated, if the translation is not complete) Docbook XML file can
1129 then be used like the original to create a PDF, HTML and epub version
1130 of the documentation.
</p
>
1132 <p
>The translators use different tools to edit the .po files. We
1134 <a href=
"http://www.kde.org/applications/development/lokalize/
">lokalize
</a
>,
1135 while some use emacs and vi, others can use web based editors like
1136 <a href=
"http://pootle.translatehouse.org/
">Poodle
</a
> or
1137 <a href=
"https://www.transifex.com/
">Transifex
</a
>. All we care about
1138 is where the .po file end up, in our git repository. Updated
1139 translations can either be committed directly to git, or submitted as
1140 <a href=
"https://bugs.debian.org/src:debian-edu-doc
">bug reports
1141 against the debian-edu-doc package
</a
>.
</p
>
1143 <p
>One challenge is images, which both might need to be translated (if
1144 they show translated user applications), and are needed in different
1145 formats when creating PDF and HTML versions (epub is a HTML version in
1146 this regard). For this we transform the original PNG images to the
1147 needed density and format during build, and have a way to provide
1148 translated images by storing translated versions in
1149 images/$LANGUAGECODE/. I am a bit unsure about the details here. The
1150 package maintainers know more.
</p
>
1152 <p
>If you wonder what the result look like, we provide
1153 <a href=
"http://maintainer.skolelinux.org/debian-edu-doc/
">the content
1154 of the documentation packages on the web
</a

1158 HTML version

1159 but perhaps it will be done in the future.

1179 wish to contribute, and I managed to get a interview with this great

1182 <p

1184 <p
>My name is Roger Marsal, I
'm
27 years old (
1986 generation) and I
1185 live in Barcelona, Spain. I
've got a strong business background and I
1186 work as a patrimony manager and as a real estate agent. Additionally,
1187 I
've co-founded a British based tech company that is nowadays on the
1188 last development phase of a new social networking concept.

1190 <p

'm a Linux enthusiast that started its journey with Ubuntu four years
1191 ago and have recently switched to Debian seeking rock solid stability
1192 and as a necessary step to gain expertise.
</p

1194 <p
>In a nutshell, I spend my days working and learning as much as I
1195 can to face both my job, entrepreneur project and feed my Linux
1198 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
1199 project?
</strong
></p
>
1201 <p
>I discovered the
<a href=
"http://www.ltsp.org/
">LTSP
</a
> advantages
1202 with
"Ubuntu
12.04 alternate install
" and after a year of use I
1203 started looking for an alternative. Even though I highly value and
1204 respect the Ubuntu project, I thought it was necessary for me to
1205 change to a more robust and stable alternative. As far as I was using
1206 Debian on my personal laptop I thought it would be fine to install
1207 Debian and configure an LTSP server myself. Surprised, I discovered
1208 that the Debian project also supported a kind of Edubuntu equivalent,
1209 and after having some pain I obtained a Debian Edu network up and
1210 running. I just loved it.
</p
>
1212 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
1213 Edu?
</strong
></p
>
1215 <p
>I found a main advantage in that, once you know
"the tips and
1216 tricks
", a new installation just works out of the box. It
's the most
1217 complete alternative I
've found to create an LTSP network. All the
1218 other distributions seems to be made of plastic, Debian Edu seems to
1219 be made of steel.

1222 Edu?

1224 <p
>I found two main disadvantages.
</p

1226 <p
>I
'm not an expert but I
've got notions and I had to spent a considerable
1227 amount of time trying to bring up a standard network topology. I
'm quite
1228 stubborn and I just worked until I did but I
'm sure many people with few
1229 resources (not big schools, but academies for example) would have switched
1230 or dropped.
</p
>
1232 <p
>It
's amazing how such a complex system like Debian Edu has achieved
1233 this out-of-the-box state. Even though tweaking without breaking gets
1234 more difficult, as more factors have to be considered. This can
1235 discourage many people too.

1246 <p
>I don
't think there is a need for a particular strategy. The free
1247 attribute in both
"freedom
" and
"no price
" meanings is what will
1248 really bring free software to schools. In my experience I can think of
1249 the
<a href=
"http://www.r-project.org/

</a
>; a
1250 few years a ago was an extremely nerd tool for university people.
1251 Today it
's being increasingly used to teach statistics at many
1252 different level of studies. I believe free and open software will
1253 increasingly gain popularity, but I
'm sure schools will be one of the
1254 first scenarios where this will happen.

>On larger sites, it is useful to use a dedicated storage server for
1264 storing user home directories and data. The design for handling this
1265 in
<a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a

1266 to update the automount rules in LDAP and let the automount daemon on

1269 <a href=

1270 on the board of directors, asked about how to do this. The steps to

</p

1275 <li
>Add new storage server in DNS. I use nas-server.intern as the
1276 example host here.
</li

1278 <li
>Add automoun LDAP information about this server in LDAP, to allow
1279 all clients to automatically mount it on reqeust.
</li
>
1281 <li
>Add the relevant entries in tjener.intern:/etc/fstab, because
1282 tjener.intern do not use automount to avoid mounting loops.
</li

1284 </ol

1286 <p

1306 <p

</a

1354 was able to get an interview with a newcomer in the project who showed
1355 up on the IRC channel a few weeks ago to let us know about his
1356 successful installation of Debian Edu Wheezy in his School. Say hello
1357 to
<a href=

1362 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
1364 <p
>I am a
23 year-old student from Germany who has spent half of his
1365 life with open source. In
"real life
", I am, as already mentioned, a
1366 student in the fields of Computer Science, Electrical Engineering,
1367 Information Technologies and Anglistics. Due to my (only partially
1368 voluntary) huge engagement in the open source world, these things are
1369 a bit vacant right now however.
</p
>
1371 <p
>I also have been working as a project teacher at a Gymasnium
1372 (public school) for various years now. I took up that work some time
1373 around
2005 when still attending that school myself and have continued
1374 it until today. I also had been running the (kind of very advanced)
1375 network of that school together with a team of very interested and
1376 talented students in the age of
11 to
15 years, who took the chance to
1377 learn a lot about open source and networking before I left the school
1378 to help building another school
's informational education concept from
1381 <p
>That said, one might see me as a kind of
"glue
" between school kids
1382 and the elderly of teachers as well as between the open source
1383 ecosystem and the (even more complex) educational ecosystem.
</p
>
1385 <p
>When I am not busy with open source or education, I like Geocaching
1386 and cycling.
</p
>
1388 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
1389 project?
</strong
></p
>
1391 <p
>I think that happened some time around
2009 when I first attended
1392 <a href=
"http://www.froscon.org
">FrOSCon
</a
> and visited the project
1393 booth. I think I wasn
't too interested back then because I used to
1394 have an attitude of disliking software that does too much stuff on its
1395 own. Maybe I was too inexperienced to realise the upsides of an
1396 "out-of-the-box
" solution ;).
</p
>
1398 <p
>The first time I actively talked to Skolelinux people was at
1399 <a href=
"http://www.openrheinruhr.de
">OpenRheinRuhr
</a
> 2011 when the
1400 BiscuIT project, a home-grewn software used by my school for various
1401 really cool things from timetables and class contact lists to lunch
1402 ordering, student ID card printing and project elections first got to
1403 a stage where it could have been published. I asked the Skolelinux
1404 guys running the booth if the project were interested in it and gave a
1405 small demonstration, but there wasn
't any real feedback and the guys
1406 seemed rather uninterested.
</p
>
1408 <p
>After I left the school where I developed the software, it got
1409 mostly lost, but I am now reimplementing it for my new school. I have
1410 reusability and compatibility in mind, and I hop there will be a new
1411 basis for contributing it to the Skolelinux project ;)!
</p
>
1413 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
1414 Edu?
</strong
></p
>
1416 <p
>The most important advantage seems to be that it
"just
1417 works
". After overcoming some minor (but still very annoying) glitches
1418 in the installer, I got a fully functional, working school network,
1419 without the month-long hassle I experienced when setting all that up
1420 from scratch in earlier years. And above that, it rocked - I didn
't
1421 have any real hardware at hand, because the school was just founded
1422 and has no money whatsoever, so I installed a combined server (main
1423 server, terminal services and workstation) in a VM on my personal
1424 notebook, bridging the LTSP network interface to the ethernet port,
1425 and then PXE-booted the Windows notebooks that were lying around from
1426 it. I could use
8 clients without any performance issues, by using a
1427 tiny little VM on a tiny little notebook. I think that
's enough to say
1428 that it rocks!
</p
>
1430 <p
>Secondly, there are marketing reasons. Life
's bad, and so no
1431 politician will ever permit a setup described as
"Debian, an universal
1432 operating system, with some really cool educational tools
" while they
1433 will be jsut fine with
"Skolelinux, a single-purpose solution for your
1434 school network
", even if both turn out to be the very same thing (yes,
1435 this is unfair towards the Skolelinux project, and must not be taken
1436 too seriously - you get the idea, anyway).
</p
>
1438 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
1439 Edu?
</strong
></p
>
1441 <p
>I have not been involved with Skolelinux long enough to really
1442 answer this question in a fair way. Thus, please allow me to put it in
1443 other words:
"What do you expect from Skolelinux to keep liking it?
" I
1444 can list a few points about that:
</p
>
1448 <li
>always strive to get all things integrated into Debian upstream
1449 <li
>be open to discussion about changes and the like, even with newcomers
1450 <li
>be helpful at being helpful ;)
1454 <p
>I
'm really sorry I cannot say much more about that :(!
</p
>
1456 <p
><strong
>Which free software do you use daily?
</strong
></p
>
1458 <p
>First of all, all software I use is free and open. I have abandoned
1459 all non-free software (except for firmware on my darned phone) this
1462 <p
>I run Debian GNU/Linux on all PC systems I use. On that, I mostly
1463 run text tools. I use
1464 <a href=
"https://www.mirbsd.org/mksh.htm
">mksh
</a
> as shell,
1465 <a href=
"https://www.mirbsd.org/jupp.htm
">jupp
</a
> as very advanced
1466 text editor (I even got the developer to help me write a script/macro
1467 based full-featured student management software with the two),
1468 <a href=
"http://mcabber.com/
">mcabber
</a
> for XMPP and
1469 <a href=
"http://www.irssi.org/
">irssi
</a
> for IRC. For that overly
1470 coloured world called the WWW, I use
1471 <a href=
"https://www.mozilla.org/en-US/firefox/new/
">Iceweasel
1472 (Firefox)
</a
>. Oh, and
<a href=
"http://www.mutt.org/
">mutt
</a
> for
1475 <p
>However, while I am personally aware of the fact that text tools
1476 are more efficient and powerful than anything else, I also use (or at
1477 least operate) some tools that are suitable to bring open source to
1478 kids. One of these things is
<a href=
"http://jappix.org/
">Jappix
</a
>,
1479 which I already introduced to some kids even before they got aware of
1480 Facebook, making them see for themselves that they do not need
1481 Facebook now ;).
</p
>
1483 <p
><strong
>Which strategy do you believe is the right one to use to
1484 get schools to use free software?
</strong
></p
>
1486 <p
>Well, that
's a two-sided thing. One side is what I believe, and one
1487 side is what I have experienced.
</p
>
1489 <p
>I believe that the right strategy is showing them the benefits. But
1490 that won
't work out as long as the acceptance of free alternatives
1491 grows globally. What I mean is that if all the kids are almost forced
1492 to use Windows, Facebook, Skype, you name it at home, they will not
1493 see why they would want to use alternatives at school. I have seen
1494 students take seat in front of a fully-functional, modern Debian
1495 desktop that could do anything their Windows at home could do, and
1496 they jsut refused to use it because
"Linux sucks
". It is something
1497 that makes the council of our city spend around
600000 € to buy
1498 software - not including hardware, mind you - for operating school
1499 networks, and for installing a system that, as has been proved, does
1500 not work. For those of you readers who are good at maths, have you
1501 already found out how many lives could have been saved with that money
1502 if we had instead used it to bring education to parts of the world
1503 that need it? I have, and found it to be nothing less dramatic than
1504 plain criminal.
</p
>
1506 <p
>That said, the only feasible way appears to be the bottom up
1507 method. We have to bring free software to kids and parents. I have
1508 founded an association named
1509 <a href=
"https://www.teckids.org
">Teckids
</a
> here in Germany that does
1510 just that. We organise several events for kids and adolescents in the
1511 area of free and open source software, for example the
1512 <a href=
"http://kids.froscon.org
">FrogLabs
</a
>, which share staff with
1513 Teckids and are the youth programme of
1514 <a href=
"http://www.froscon.org
">the Free and Open Source Software
1515 Conference (FrOSCon)
</a
>. We do a lot more than most other conferences
1516 - this year, we first offered the FrogLabs as a holiday camp for kids
1517 aged
10 to
16. It was a huge success, with approx.
30 kids taking part
1518 and learning with and about free software through a whole weekend. All
1519 of us had a lot of fun, and the results were really exciting.
</p
>
1521 <p
>Apart from that, we are preparing a campaign that is supposed to bring
1522 the message of free alternatives to stuff kids use every day to them and
1523 their parents, e.g. the use of Jabber / Jappix instead of Facebook and
1524 Skype. To make that possible, we are planning to get together a team of
1525 clever kids who understand very well what their peers need and can bring
1526 it across to them. So we will have a peer-driven network of adolescents
1527 who teach each other and collect feedback from the community of minors.
1528 We then take that feedback and our own experience to work closely with
1529 open source projects, such as Skolelinux or Jappix, at improving their
1530 software in a way that makes it more and more attractive for the target
1531 group. At least I hope that we will have good cooperation with
1532 Skolelinux in the future ;)!
</p
>
1534 <p
>So in conclusion, what I believe is that, if it weren
't for the world
1535 being so bad, it should be very clear to the political decision makers
1536 that the only way to go nowadays is free software for various reasons,
1537 but I have learnt that the only way that seems to work is bottom up.
</p
>
1541 > * Who should be interviewed with this questions in the future?
1543 That
's probably the hardest question of them all, as I do not know the
1544 community. However, I would be willing to do the following:
1546 <li
>Run an interview with a German headteacher who is very open to
1547 free software, and also prefers it, but cannot really use it because
1548 of the decision makers above;
1549 <li
>Run interviews with some kids, both with and without previous
1550 knowledge about free software
1552 If that is wanted, just let me know ;).

1580 <p

1611 <p
><strong

1612 Edu?
</strong
></p
>
1615 <li
>Skolelinux is - as we had to learn - not easily upgradable to
1616 the next version. Opposed to its genuine Debian base, upgrading to
1617 a new version means a full new installation from scratch to get it
1618 working again reliably.
1620 <li
>Skolelinux is based on Debian/stable, and therefore always a
1621 little outdated in terms of program versions compared to Edubuntu or
1622 similar educational Linux distros, which rather use Debian/testing
1625 <li
>Skolelinux has some very self-opinionated and stubborn default
1626 configuration which in my opinion adds unnecessary complexity and is
1627 not always suitable for a schools needs, the preset network
1628 configuration is actually a core definition feature of Skolelinux
1629 and not easy to change, so schools sometimes have to change their
1630 network configuration to make it
"Skolelinux-compatible
".
1632 <li
>Some proposed extensions, which were made available as
1633 contribution, like secure examination mode and lecture material
1634 distribution and collection, were not accepted into the mainline
1635 Skolelinux development and are now not easy to maintain in the
1636 future because of Skolelinux somewhat undeterministic update
1639 <li
>Skolelinux has only a very tiny number of base developers
1640 compared to Debian.
</li
>
1644 <p
>For these reasons and experience from our project, I would now
1645 rather consider using plain Debian for schools next time, until
1646 Skolelinux is more closely integrated into Debian and becomes
1647 upgradeable without reinstallation.

>About Debian Edu and Skolelinux
</p
>
1808 <p
>Debian Edu, also known as Skolelinux, is a Linux distribution based
1809 on Debian providing an out-of-the box environment of a completely
1810 configured school network. Immediately after installation a school
1811 server running all services needed for a school network is set up just
1812 waiting for users and machines being added via GOsa², a comfortable
1813 Web-UI. A netbooting environment is prepared using PXE, so after
1814 initial installation of the main server from CD or USB stick all other
1815 machines can be installed via the network. The provided school server
1816 provides LDAP database and Kerberos authentication service,
1817 centralized home directories, DHCP server, web proxy and many other
1818 services. The desktop contains more than
60 educational software
1819 packages and more are available from the Debian archive, and schools
1820 can choose between KDE, Gnome, LXDE and Xfce desktop environment.
</p
>
1822 <p
>This is the seventh test release based on Debian Wheezy. Basically
1823 this is an updated and slightly improved version compared to the
1824 Squeeze release.
</p
>
1826 <p
>Notes for upgrades from Alpha Prereleases
</p
>
1828 <p
>Alpha based installations should reinstall or downgrade the
1829 versions of gosa and libpam-mklocaluser to the ones used in this beta
1830 release. Both alpha and beta0 based installations should reinstall or
1831 deal with gosa.conf manually; there are two options: (
1) Keep
1832 gosa.conf and edit this file as outlined on the mailing list. (
2)
1833 Accept the new version of gosa.conf and replace both contained admin
1834 password placeholders with the password hashes found in the old one
1835 (backup copy!). In both cases all users need to change their password
1836 to make sure a password is set for CIFS access to their home
1837 directory.

">Debian Edu, also known as
2149 Skolelinux
</a
>, is a Linux distribution based on Debian providing an
2150 out-of-the box environment of a completely configured school
2151 network. Immediately after installation a school server running all
2152 services needed for a school network is set up just waiting for users
2153 and machines being added via GOsa², a comfortable Web-UI. A netbooting
2154 environment is prepared using PXE, so after initial installation of
2155 the main server from CD, DVD or USB stick all other machines can be
2156 installed via the network. The provided school server provides LDAP
2157 database and Kerberos authentication service, centralized home
2158 directories, DHCP server, web proxy and many other services. The
2160 <a href=

">more
2161 than
60 educational software packages
</a
> and more are available from
2162 the Debian archive, and schools can choose between KDE, Gnome, LXDE
2163 and Xfce desktop environment.
</p
>
2165 <p
>This is the fourth test release based on Debian Wheezy. Basically
2166 this is an updated and slightly improved version compared to the
2167 Squeeze release.
</p
>
2169 <p
><strong
>Software updates
</strong
></p
>
2171 <li
>Dropped ispell dictionaries from our default installation.
</li
>
2172 <li
>Dropped menu-xdg from the KDE desktop option, to drop the Debian
2173 submenu. It was not included with Gnome, LXDE or Xfce, so this
2174 brings KDE in line with the others.
</li
>
2175 <li
>Dropped xdrawchem, xjig and xsok from our default installation as
2176 they don
't have a desktop menu entry and thus won
't show up in the
2177 menu now that menu-xdg was removed.
</li
>
2178 <li
>Removed the killer system to kill left behind processes on
2179 multi-user machines, as it was no longer able to understand when a
2180 X display was in use and killed the processes of the active users
2182 <li
>Dropped the golearn (from goplay) package as the debtags in wheezy
2183 are too few to make the package useful.
</li
>
2185 <p
><strong
>Other changes
</strong
></p
>
2187 <li
>Updated artwork matching http://wiki.debian.org/DebianArt/Themes/Joy
2188 <li
>Multi-arch i386/amd64 USB stick ISO available.
</li
>
2189 <li
>Got rid of ispell/wordlist related debconf questions that showed
2190 up for some language options.
</li
>
2191 <li
>Switched to using http.debian.net as APT source by default.
</li
>
2192 <li
>Fixed proxy configuration on Main Server installations.
</li
>
2193 <li
>Changed LTSP setup to ask dpkg to use force-unsafe-io the same way
2194 d-i is doing it.
</li
>
2195 <li
>Made sure root and user passwords were not left behind in the
2196 debconf database after installation on Main Server installations.
</li
>
2197 <li
>Made Roaming Workstation dynamic setup more robust and added draft
2198 script setup-ad-client to hook a Roaming Workstation up to a
2199 Active Directory server instead of a Debian Edu Main Server.
</li
>
2200 <li
>Update system to install needed firmware packages during
2201 installation, to work properly in Wheezy.
</li
>
2202 <li
>Update system to handle hardware quirks (debian-edu-hwsetup).
</li
>
2203 <li
>Corrected PXE installation setup to properly pass selected desktop
2204 and keymap settings to PXE installation clients.
</li
>
2205 <li
>LTSP diskless workstations use sshfs by default, allowing them to
2206 work without adding them to DNS and NIS netgroups for NFS access.

2247 <description><p
>In the
<a href=
"http://www.skolelinux.org/
">Debian Edu /
2248 Skolelinux
</a
> project, we include a post-installation test suite,
2249 which check that services are running, working, and return the
2250 expected results. It runs automatically just after the first boot on
2251 test installations (using test ISOs), but not on production
2252 installations (using non-test ISOs). It test that the LDAP service is
2253 operating, Kerberos is responding, DNS is replying, file systems are
2254 online resizable, etc, etc. And it check that the PXE service is
2255 configured, which is the topic of this post.
</p
>
2257 <p
>The last week I
've fixed the DVD and USB stick ISOs for our Debian
2258 Edu Wheezy release. These ISOs are supposed to be able to install a
2259 complete system without any Internet connection, but for that to
2260 happen all the needed packages need to be on them. Thanks to our test
2261 suite, I discovered that we had forgotten to adjust our PXE setup to
2262 cope with the new names and paths used by the netboot d-i packages.
2263 When Internet connectivity was available, the installer fall back to
2264 using wget to fetch d-i boot images, but when offline it require
2265 working packages to get it working. And the packages changed name
2266 from debian-installer-
6.0-netboot-$arch to
2267 debian-installer-
7.0-netboot-$arch, we no longer pulled in the
2268 packages during installation. Without our test suite, I suspect we
2269 would never have discovered this before release. Now it is fixed
2270 right after we got the ISOs operational.
</p
>
2272 <p
>Another by-product of the test suite is that we can ask system
2273 administrators with problems getting Debian Edu to work, to run the
2274 test suite using
<tt
>/usr/sbin/debian-edu-test-install
</tt
> and see if
2275 any errors are detected. This usually pinpoint the subsystem causing
2276 the problem.

><strong
>Who are you, and how do you spend your days?
</strong
></p
>
2303 <p
>I
'm a
25 year old free software enthusiast, living in Romania,
2304 which is also my country of origin. Back in
2009, at a New Year
's Eve
2305 party, I had a very nice
<strike
>beer
</strike
> discussion with a
2306 friend, when we realized we have no organised Debian community in our
2307 country. A few days later, we put together the infrastructure for such
2308 community and even gathered a nice Debian-ish crowd. Since then, I
2309 began my quest as a free software hacker and activist and I am
2310 constantly trying to cover as much ground as possible on that
2313 <p
>A few years ago I founded a small web development company, which
2314 provided me the flexible schedule I needed so much for my
2315 activities. For the last
13 months, I have been the Technical Director
2316 of
<a href=
"http://ceata.org/
">Fundația Ceata
</a
>, which is a free
2317 software activist organisation endorsed by the FSF and the FSFE, and
2318 the only one we have in our country.
</p
>
2320 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
2321 project?
</strong
></p
>
2323 <p
>The idea of participating in the Debian Edu project was a surprise
2324 even to me, since I never used it before I began getting involved in
2325 it. This year I had a great opportunity to deliver a talk on
2326 educational software, and I knew immediately where to look. It was a
2327 love at first sight, since I was previously involved with some of the
2328 technologies the project incorporates, and I rapidly found a lot of
2329 ways to contribute.
</p
>
2331 <p
>My first contributions consisted in translating the installer and
2332 configuration dialogs, then I found some bugs to squash (I still
2333 haven
't fixed them yet though), and I even got my eyes on some other
2334 areas where I can prove myself helpful. Since the appetite for free
2335 software in my country is pretty low, I
'll be happy to be the first
2336 one around here advocating for the project
's adoption in educational
2337 environments, and maybe even get my hands dirty in creating a flavour
2338 for our own needs. I am not used to make very advanced plannings, so
2339 from now on, time will tell what I
'll be doing next, but I think I
2340 have a pretty consistent starting point.
</p
>
2342 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
2343 Edu?
</strong
></p
>
2345 <p
>Not a long time ago, I was in the position of configuring and
2346 maintaining a LDAP server on some Debian derivative, and I must say it
2347 took me a while. A long time ago, I was maintaining a bigger
2348 Samba-powered infrastructure, and I must say I spent quite a lot of
2349 time on it. I have similar stories about many of the services included
2350 with Skolelinux, and the main advantage I see about it is the
2351 out-of-the box availability of them, making it quite competitive when
2352 it comes to managing a school
's network, for example.
</p
>
2354 <p
>Of course, there is more to say about Skolelinux than the
2355 availability of the software included, its flexibility in various
2356 scenarios is something I can
't wait to experiment
"into the wild
" (I
2357 only played with virtual machines so far). And I am sure there is a
2358 lot more I haven
't discovered yet about it, being so new within the
2361 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
2362 Edu?
</strong
></p
>
2364 <p
>As usual, when it comes to Debian Blends, I see as the biggest
2365 disadvantage the lack of a numerous team dedicated to the
2366 project. Every day I see the same names in the changelogs, and I have
2367 a constantly fear of the bus factor in this story. I
'd like to see
2368 Debian Edu advertised more as an entry point into the Debian
2369 ecosystem, especially amongst newcomers and students. IMHO there are a
2370 lot low-hanging fruits in terms of bug squashing, and enough
2371 opportunities to get the feeling of the Debian Project
's dynamics. Not
2372 to mention it
's a very fun blend to work on!
</p
>
2374 <p
>Derived from the previous statement, is the delay in catching up
2375 with the main Debian release and documentation. This is common though
2376 to all blends and derivatives, but it
's an issue we can all work
2379 <p
><strong
>Which free software do you use daily?
</strong
></p
>
2381 <p
>I can hardly imagine myself spending a day without Vim, since my
2382 daily routine covers writing code and hacking configuration files. I
2383 am a fan of the Awesome window manager (but I also like the
2384 Enlightenment project a lot!),
2385 <a href=
"http://www.claws-mail.org/

2386 use and very configurable behaviour. Recently I fell in love with
2387 <a href=
"https://launchpad.net/redshift

</a
>, which helps me
2388 get through the night without headaches. Of course, there is much more
2389 stuff in this bag, but I
'll need a blog on my own for doing this!

2391 <p
><strong
>Which strategy do you believe is the right one to use to
2392 get schools to use free software?
</strong

>
2394 <p
>Well, on this field, I cannot do much more than experiment right
2395 now. So, being far from having a recipe for success, I can only assume
2400 <li
>schools would like to get rid of proprietary software
</li
>
2402 <li
>students will love the openness of the system, and will want to
2403 experiment with it - maybe we need to harvest the native curiosity
2404 of teenagers more?
</li
>
2406 <li
>there is no
"right one
" when it comes to strategies, but it would
2407 be useful to have some success stories published somewhere, so
2408 other can get some inspiration from them (I know I
'd promote
2411 <li
>more active promotion - talks, conferences, even small school
2412 lectures can do magical things if they encounter at least one
2413 person interested. Who knows who that person might be? ;-)
</li
>
2417 <p
>I also see some problems in getting Skolelinux into schools; for
2418 example, in our country we have a great deal of corruption issues, so
2419 it might be hard(er) to fight against proprietary solutions. Also,
2420 people who relied on commercial software for all their lives, would be
2421 very hard to convert against their will.

>How did you get in contact with the Skolelinux / Debian Edu
2448 project?
</strong

2450 <p
>I
've been somewhat familiar with the project before, but I think my
2451 first direct exposure to the project was when I met Petter
2452 [Reinholdtsen] and Knut [Yrvin] at the Edubuntu summit in
2005 in
2453 London. They provided great feedback that helped the bootstrapping of
2454 Edubuntu. Back then Edubuntu (and even Ubuntu) was still very new and
2455 it was great getting input from people who have been around longer. I
2456 was also still very excitable and said yes to everything and to this
2457 day I have a big todo list backlog that I
'm catching up with. I think
2458 over the years the relationship between Edubuntu and Debian-Edu has
2459 been gradually improving, although I think there
's a lot that we could
2460 still improve on in terms of working together on packages. I
'm sure
2461 we
'll get there one day.

2463 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
2464 Edu?
</strong
></p

2466 <p
>Debian itself already has so many advantages. I could go on about
2467 it for pages, but in essence I love that it
's a very honest project
2468 that puts its users first with no hidden agendas and also produces
2469 very high quality work.
</p
>
2471 <p
>I think the advantage of Debian Edu is that it makes many common
2472 set-up tasks simpler so that administrators can get up and running
2473 with a lot less effort and frustration. At the same time I think it
2474 helps to standardise installations in schools so that it
's easier for
2475 community members and commercial suppliers to support.

>What do you see as the disadvantages of Skolelinux / Debian
2478 Edu?
</strong

2480 <p
>I had to re-type this one a few times because I
'm trying to
2481 separate
"disadvantages
" from
"areas that need improvement
" (which is
2482 what I originally rambled on about)
</p
>
2484 <p
>The biggest disadvantage I can think of is lack of manpower. The
2485 project could do so much more if there were more good contributors. I
2486 think some of the problems are external too. Free software and free
2487 content in education is a no-brainer but it takes some time to catch
2488 on. When you
've been working with the same proprietary eco-system for
2489 years and have gotten used to it, it can be hard to adjust to some
2490 concepts in the free software world. It would be nice if there were
2491 more Debian Edu consultants across the world. I
'd love to be one
2492 myself but I
'm already so over-committed that it
's just not possible
2493 currently.
</p
>
2495 <p
>I think the best short-term solution to that large-scale problem is
2496 for schools to be pro-active and share their experiences and grow
2497 their skills in-house. I
'm often saddened to see how much money
2498 educational institutions spend on
3rd party solutions that they don
't
2499 have access to after the service has ended and they could
've gotten so
2500 much more value otherwise by being more self-sustainable and
2501 autonomous.

">Debian Edu, also known as
2568 Skolelinux
</a
>, is a Linux distribution based on Debian providing an
2569 out-of-the box environment of a completely configured school
2570 network. Immediately after installation a school server running all
2571 services needed for a school network is set up just waiting for users
2572 and machines being added via GOsa², a comfortable Web-UI. A netbooting
2573 environment is prepared using PXE, so after initial installation of
2574 the main server from CD, DVD or USB stick all other machines can be
2575 installed via the network. The provided school server provides LDAP
2576 database and Kerberos authentication service, centralized home
2577 directories, DHCP server, web proxy and many other services. The

2711 interview last November. But the developers and translators are still
2712 pulling along to get the Wheezy based release out the door, and this
2713 time I managed to get an interview from one of the French translators
2714 in the project, Cédric Boutillier.

2719 professor in probability theory. I spend my daytime teaching
2720 mathematics at the university and doing fundamental research in
2721 probability in connexion with combinatorics and statistical physics.
</p

2723 <p
>I have been involved in the Debian project for a couple of years
2724 and became Debian Developer a few months ago. I am working on Ruby
2725 packaging, publicity and translation.

2728 project?
</strong

2730 <p
>I came to the Debian Edu project after a call for translation of
2731 <a href=
"http://wiki.debian.org/DebianEdu/Documentation/Manuals

2732 Debian Edu manual

2737 virtual machine when I was preparing localised version of some screen
2738 shots for the manual. I was amazed to see it worked out of the box and
2739 how comprehensive the list of software installed by default was.
</p
>
2741 <p
>What amazed me was the complete network infrastructure directly
2742 ready to use, which can and the nice administration interface provided
2743 by
<a href=
"https://oss.gonicus.de/labs/gosa/
">GOsa²
</a
>. What pleased
2744 me also was the fact that among the software installed by default,
2745 there were many
"traditional
" educative software to learn languages,
2746 to count, to program... but also software to develop creativity and
2747 artistic skills with music (
<a href=

2757 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
2758 Edu?
</strong
></p
>
2760 <p
>For me, the main advantages of Skolelinux/Debian Edu are its
2761 community of experts and its precise documentation, as well as the
2762 fact that it provides a solution ready to use.
</p
>
2764 <p
>I would add also the fact that it is based on the rock solid Debian
2765 distribution, which ensures stability and provides a huge collection
2766 of educational free software.

>
2768 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
2769 Edu?
</strong
></p
>
2771 <p
>Maybe the lack of manpower to do lobbying on the
2772 project. Sometimes, people who need to take decisions concerning IT do
2773 not have all the elements to evaluate properly free software
2774 solutions. The fact that support by a company may be difficult to find
2775 is probably a problem if the school does not have IT personnel.
</p
>
2777 <p
>One can find support from a company by looking at
2778 <a href=
"http://wiki.debian.org/DebianEdu/Help/ProfessionalHelp
">the
2779 wiki dokumentation
</a
>, where some countries already have a number of
2780 companies providing support for Debian Edu, like Germany or
2781 Norway. This list is easy to find readily from the manual. However,
2782 for other countries, like France, the list is empty. I guess that
2783 consultants proposing support for Debian would be able to provide some
2784 support for Debian Edu as well.
</p
>
2786 <p
><strong
>Which free software do you use daily?
</strong

>
2788 <p
>I am using the KDE Plasma Desktop. But the pieces of software I use
2789 most runs in a terminal: Mutt and OfflineIMAP for emails, latex for
2790 scientific documents, mpd for music. VIM is my editor of choice. I am
2791 also using the mathematical software
2792 <a href=

2801 university, we use both

2999 <p
>Jeg heter Nirosan Thiyagalingam. Jeg er
24 år og studerer
3000 dataingeniør studiet ved Høgskolen i Sør Trøndelag. Interessen for
3001 data har siden ung alder vært tilstede og jeg har i tillegg alltid
3002 vært glad i å lære nye ting. Med teknologi som endres svært hurtig er
3003 det alltid noe nytt å lære. Noe som igjen har gjort det svært
3004 interessant å følge med på utviklingen. Jeg valgte dataingeniør
3005 studiet grunnet ønske om å lære enda mer om programmering og utvikling
3006 av store systemer.
</p
>
3008 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
3010 <p
>Skolelinux prosjektet hørte jeg først om i media. Men det var først
3011 når jeg skulle velge bacheloroppgave at jeg fattet mer interesse for
3012 prosjektet. Et enkelt søk på nettet førte meg til skolelinux sine
3013 hjemmesider. Informasjonen jeg fant der gjorde meg enda nysgjerrig og
3014 jeg valgte derfor en oppgave som gikk ut på å få en
3015 <a href=
"http://www.raspberrypi.org
">Raspberry PI
</a
>. Altså en
3016 ultra-billig datamaskin til å kjøre Debian Edu på lik linje med
3017 vanlige datamaskiner. I løpet av prosjektet ble det gjort mye
3018 forskning på nettet. Det var mye jeg måtte forstå rundt hvordan
3019 operativsystemet Linux fungerte før jeg kunne angripe
3020 problemet. Prøvde først å finne ut hvordan man kunne transformere en
3021 vanlig installasjon av Skolelinux til Raspberry PI, men dette var
3022 altfor vanskelig å jeg endte opp med mer spørsmål enn svar. Det ble
3023 videre opprettet kontakt med Skolelinux utviklere på IRC der jeg fikk
3024 diskutert hvilken retning jeg burde gå for å få til en fullverdig
3025 løsning. Det ble bestemt at jeg skulle gå for å først installere
3026 <a href=
"http://www.raspbian.org/
">Raspian
</a
>. Dette er et
3027 operativsystem basert på Debian spesiallaget for Raspberry Pi sin
3028 maskinvare. Nå som Debian var installert på datamaskinen gjenstod det
3029 å installere de nødvendige Skolelinux pakkene for å få til et
3030 fullverdig system. Disse pakkene ble installert manuelt i første
3031 omgang, men ble senere installert automatisk via et script som Petter
3032 Reinholdtsen laget. Dette scriptet er så enkel å bruke at man er i
3033 gang med installasjonen i løpet av bare
5 minutter. Ikke nok med det,
3034 alt skjer helt automatisk. Alt i alt er jeg veldig fornøyd med
3035 resultatet av installasjonsprosessen. Raspberry Pi er en veldig svak
3036 maskin og det merkes godt når man har installert Skolelinux på
3037 den. Video og
3D-rendering fungerer utrolig dårlig, men nettsurfing og
3038 kontorprogrammer fungerer godt. Det kan derfor konkluderes med at
3039 datamaskinen er egnet for enkle oppgaver.
3041 <p
>Jeg syns det er viktig påpeke at dette kun er startfasen av en slik
3042 løsning. På markedet finnes det nå maskiner som har bedre hardware enn
3043 Raspberry Pi. Det er store muligheter for at man kan klare å
3044 installere Skolelinux på disse også, og da forsvinner nok mest
3045 sannsynlig ytelsesproblemene med Video og
3D rendering også.
</p
>
3047 <p
>Det ble også prøvd med en løsning som gjorde at Raspberry Pi
3048 fungerte som en tynnklient. Denne løsningen hadde langt bedre ytelse
3049 med tanke på hastighet og brukeropplevelse. Men også her var video og
3050 3D rendering dårlig. Det ble brukt en liten Linux distribusjon kalt
3051 <a href=

</a
> for å få til
3054 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
3056 <p
>Fordelen med Skolelinux er mange. At det er gratis er en stor
3057 fordel, men at det er så mange som er med på å utvikle det og
3058 vedlikeholde det er en enda større fordel. Allerede før jeg startet
3059 med prosjektet så jeg mange fordeler, og når jeg nærmet meg sluttfasen
3060 så jeg langt flere. At prosjektet skulle inneha en så høy kvalitet
3061 hadde jeg aldri trodd. En vanlig Skolelinux installasjon har de
3062 nødvendige programmene og funksjonen som både små og store skoler i
3063 tillegg til organisasjoner kan klare seg med. At prosjektet tilbyr en
3064 så komplett løsning er en kjempefordel. Installasjonen er knirkefri
3065 og det er svært enkelt å installere og komme i gang.
</p
>
3067 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
3069 <p
>Ulempene jeg ser med prosjektet er ryddigheten av websidene. Selv
3070 om websidene er enkle og konsise er det allikevel ikke appellerende i
3071 like stor grad som for eksempel
3072 <a href=
"http://www.ubuntu.com
">Ubuntu
</a
> sine sider. Deres side
3073 tilbyr, i tillegg til godt design og presentasjon, en nettbasert
3074 emulator av deres operativsystem. Dette er en stor fordel slik jeg ser
3075 det. Bortsett fra dette ser jeg absolutt ingen ulemper med
3076 Skolelinux-prosjektet.
</p

3078 <p
><strong
>Hvilken fri programvare bruker du til daglig?

3080 <p
>Til daglig er jeg en flittig bruker av det åpne media
3081 sentersystemet
<a href=
"http://xbmc.org/
">XBMC
</a
>. Det enorme
3082 samfunnet rundt dette prosjektet har gjort dette til et program som
3083 dekker alles behov. Man kan tilpasse det akkurat slik man vil både med
3084 tanke på utseende og funksjoner ved installere plug-ins eller
3087 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
3088 skoler til å ta i bruk fri programvare?
</strong
></p
>
3090 <p
>Strategien som burde brukes sett fra mine øyne er
3091 markedsføring. Jeg er sikker på at om flere skoler fikk et lite innsyn
3092 i hvor bra Skolelinux er så ville de ikke nølt med å gå over fra noe
3093 annet som koster de store summer. At skolelinux til de grader tilbyr
3094 en så komplett løsning bure komme frem. Enten via reklamekampanjer
3095 eller ved å sende ut folk til skoler for så å la skolenettverk
3096 ansvarlige få teste ut hvordan Skolelinux fungerer i praksis. Om det
3097 i tillegg ble utviklet gode websider og en emulator for å la brukere
3098 prøve operativsystemet ville nok dette ha styrket inntrykket
3099 betraktelig.

3193 <p
>Debian Edu, also known as Skolelinux, is a Linux distribution based
3194 on Debian providing an out-of-the box environment of a completely
3195 configured school network. Immediatly after installation a school
3196 server running all services needed for a school network is set up just
3197 waiting for users and machines being added via GOsa², a comfortable
3198 Web-UI. A netbooting environment is prepared using PXE, so after
3199 initial installation of the main server from CD, DVD or USB stick all
3200 other machines can be installed via the network.

">Debian Edu, also known as
3353 Skolelinux
</a

3354 out-of-the box environment of a completely configured school
3355 network. Immediatly after installation a school server running all
3356 services needed for a school network is set up just waiting for users
3357 and machines being added via GOsa², a comfortable Web-UI. A netbooting
3358 environment is prepared using PXE, so after initial installation of
3359 the main server from CD, DVD or USB stick all other machines can be
3360 installed via the network.

6. He installed the standalone profile and
3486 the video show a walk-through of of the menu content, demonstration of
3487 a few programs and his view of our distribution.
</p
>
3489 <p
>There is also some really nice quotes (transcribed by me, might
3490 have heard wrong). While looking thought the Graphics menu:
</p
>
3493 "Basically everything you ever need in a school environment.
"
3496 <p
>And as a general evaluation of the entire distribution:
</p
>
3499 "So, yeah, a bit bloated. It kept all the Debian stuff in there, just
3500 to keep it nice and GNU. So, I do not want to go on about it, but
3501 lets give it
7 out of
10. I am not going to use it. That is because
3502 I am not deploying a school network. There may be some mythical
3503 feature to help you deploy Skolelinux on a school network.
"
3506 <p
>To bad he did not test the server profile, and discovered the PXE
3507 installation option. It make it possible to install only the main
3508 server from CD, and the rest of the machines via the net, and might be
3509 considered the mythical feature he talk about. :)
</p
>
3511 <p
>While looking through the menus, there is also this funny comment
3512 about the part of the K menu generated from the Debian menu subsystem:
3515 "[The K menu] have a special Debian section for software that no-one
3516 is going to look at, because it contain lots of junky stuff that you
3517 actually don
't need in the education distribution, but have just been
3518 included because it isn
't stripped out for some reason.
"
3521 <p
>I guess it is yet another argument for merging the Debian menu and
3522 Gnome/KDE desktop menu entries into
3523 <a href=
"http://wiki.debian.org/Proposals/DebianMenuUsingDesktopEntries
">one
3524 consistent menu system
</a
> instead of two incomplete and partly
3525 inconsistent menu systems.

3646 drifter nettverk og maskiner for små og mellomstore firma

2 ansatte. Min faglege bakgrunn
3648 er Fagbrev som it-teknikker, samt nokre fag innen nettverk- og

3650 maskiner og hjelp til sluttbrukere, samt oppsett og vedlikehold av eit
3651 vidt spekter av fagsystemer ute hjå kunder. Erfaring med Skolelinux
3652 har eg hatt i forbindelse med drifting av

3667 <p
>Fordelane med Skolelinux er sentralisert administrasjon og svært
3668 mange gode verktøy «ut av boksen». Veldig kjekt å kunne drifte
60
3669 klientar med berre å «bry» seg med ein server. Levetid for systemets
3670 hardware er og ein veldig fin effekt. I tillegg kjem fordelar som økt
3671 sikkerhet og mindre lisenskostnader. Etter min erfaring er det og
3672 mykje mindre driftskostnader med eit slikt system enn konkurrerande
3673 system, pga enkelhet med sentralisert administrasjon. På grunn av at
3674 Skolelinux er basert på Debian er det òg svært stabilt.
</p

3676 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
3678 <p
>Ulemper er mangel på vilje til å følge standarer ute i markedet,
3679 som fører til mangel på støtte til nokre mykje brukte ting. Flash og
3680 Java er typiske eksempel. Sidan Debian satsar på stabilitet framfor å
3681 ha nyeste pakke av eit program, kan ein i nokre tilfeller kome borti
3682 at program vert «for gamle». Det er spesielt nettlesaren som er
3683 utsett. Mangel på vilje til å utvikle pedagogisk programvare, i Noreg,
3684 for «alle» platformer fører òg til noko hovudbry.
</p
>
3686 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
3688 <p
>Til dagleg bruker eg svært mange forskjellige «fri programvare»
3689 program. Firefox, Thunderbird, Freecommander, ImgBurn, Clonezilla,
3690 OCS inventory, Icinga, Skolelinux, SystemRescueCD og mykje meir.
</p
>
3692 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
3693 skoler til å ta i bruk fri programvare?
</strong
></p
>
3695 <p
>Strategisk må ein fokusere på at sluttbruker eigentleg ikkje er så
3696 fokusert på at det er fri programvare men at det skal «berre fungere».
3697 Gjer det enkelt å bruker og ikkje minst å administrere. For Skolelinux
3698 sin del må ein få eit betre fokus på overganger. Utbytting av servere
3699 må gå meir automatisk, import og eksport av brukerbase og maskinbase
3700 med meir må kunne gå enkelt og oppgradering til neste versjon må bli
3701 mykje meir automatisk og gjennomtesta. Ein må unngå at ein må sette
3702 opp frå start når ein byter ut ein server eller oppgraderer til neste
3703 versjon. For å få Skolelinux til å bli eit betre alternativ for skular
3704 må ein ha fokus på nettlesaren. Denne må bli «up to date» og støtte
3705 dei protokollar og tillegg som vert brukt av forlag med meir. Etter
3706 kvart som meir og meir blir flytta ut i «skya» vert dette viktigare og
3707 viktigare. Ein kunne ynskje og jobbe for at forlag med fleire tar i
3708 bruk opne standarer, men inntil det skjer, må systemet kunne brukast
3709 mot desse fagsystema.
</p
>
3711 <p
>For meg har prosjektet med Skolelinux vore ein svært artig og
3712 lærerik prosess. Miljøet rundt er ikkje enormt stort, dog stort nok,
3713 men det er svært hjelpevillig og engasjert.

3808 if you know about someone I should interview, Please send me an email.
3809 After asking for many months, I finally managed to lure another one of
3810 the people behind the German

3813 welcome to Angela Fuß. :)
</p
>
3815 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
3817 <p
>I am a
39-year-old woman living in the very north of Germany near
3818 Denmark. I live in a patchwork family with
"my man
" Mike Gabriel, my
3819 two daughters, Mikes daughter and Mikes and my rather newborn son.
3821 <p
>At the moment - because of our little baby - I am spending most of
3822 the day by being a caring and organising mom for all the kids.
3823 Besides that I am really involved into and occupied with several inner
3824 growth processes: New born souls always bring the whole familiar
3825 system into movement and that needs time and focus ;-). We are also
3826 in the middle of buying a house and moving to it.
</p
>
3828 <p
>In
2013 I will work again in my job in a German foundation for
3829 nature conservation. I am doing public relation work there. Besides
3830 that - and that is the connection to Skolelinux / Debian Edu - I am
3831 working in our own school project
"IT-Zukunft Schule
" in North
3832 Germany. I am responsible for the quality assurance, the customer
3833 relationship management and the communication processes in the
3836 <p
>Since
2001 I constantly have been training myself in communication
3837 and leadership. Besides that I am a forester, a landscaping gardener
3838 and a yoga teacher.
</p
>
3840 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
3841 project?
</strong
></p
>
3843 <p
>I fell in love with Mike ;-).
</p
>
3845 <p
>Very soon after getting to know him I was completely enrolled into
3846 Free Software. At this time Mike did IT-services for one newly
3847 founded school in Kiel. Other schools in Kiel needed concepts for
3848 their IT environment. Often when Mike came home from working at the
3849 newly founded school I found myself listening to his complaints about
3850 several points where the communication with the schools head or the
3851 teachers did not work. So we were clear that he would not work for
3852 one more school if we did not set up a structure for communication
3853 between him, the schools head, the teachers, the students and the
3856 <p
>Together with our friend and hardware supplier Andreas Buchholz we
3857 started to get an overview of free software solutions suitable for
3858 schools. One day before Christmas
2010 Mike and I had a date with Kurt
3859 Gramlich in Gütersloh. As Kurt and I are really interested in building
3860 networks of people and in being in communication we dived into
3861 Skolelinux and brought it to the first grammar schools in Northern

3868 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
3869 Edu?
</strong
></p
>
3871 <p
>First I have to say: I cannot answer this question technically. My
3872 answer comes rather from a social point of view.
</p
>
3874 <p
>The biggest advantage of Skolelinux / Debian Edu I see is the large
3875 and strong international community of Debian Developers in the
3876 background which is very alive and connected over mailinglists, blogs
3877 and meetings. My constant feeling for the Debian Community is: If
3878 something does not work they will somehow fix it. All is well
3879 ;-). This is of course a user experience. What I also get as a big
3880 advantage of Skolelinux / Debian Edu is that everybody who uses it and
3881 works with it can also contribute to it - that includes students,
3882 teachers, parents...
</p
>
3884 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
3885 Edu?
</strong
></p
>
3887 <p
>I will answer this question relating to the internal structure of
3888 Skolelinux / Debian Edu.
</p
>
3890 <p
>What I see as a major disadvantage is that there is a gap between
3891 the group of developers for Debian Edu and the people who make the
3892 marketing, that means the people that bring Skolelinux to the
3893 schools. There is a lack of communication between these two groups and
3894 I think that does not really work for Skolelinux / Debian Edu.
</p
>
3896 <p
>Further I appreciate that Skolelinux / Debian Edu is known as a
3897 do-ocracy. Nevertheless I keep asking myself if at some points a
3898 democracy or some kind of hierarchical project structure would be good
3899 and helpful. I am also missing some kind of contact between the
3900 Skolelinux / Debian Edu communities in Europe or on an international
3901 level. I think it would be good if there was more sharing between the
3902 different countries using Skolelinux / Debian Edu.
</p
>
3904 <p
><strong
>Which free software do you use daily?
</strong
></p
>
3906 <p
>On my laptop I am still using an Ubuntu
10.04 with a Gnome Desktop
3907 on. As applications I use Openoffice.org, Gedit, Firefox, Pidgin,
3908 LaTeX and GnuCash. For mails I am using Horde. And I am really fond of
3909 my N900 running with Maemo.
</p
>
3911 <p
><strong
>Which strategy do you believe is the right one to use to
3912 get schools to use free software?
</strong
></p
>
3914 <p
>I am really convinced that in our school project
"IT-Zukunft
3915 Schule
" we have developed (and keep developing) a great way to get
3916 schools to use Free Software. We have written a detailed concept for
3917 that so I cannot explain the whole thing here. But in a nutshell the
3918 strategy has three crucial pillars:
</p
>
3922 <li
>We really take time to get what sort of stories, questions and
3923 concerns the schools head and the teachers have about using different
3924 kinds of IT and we take time to enrol them into Free Software.
</li
>
3926 <li
>Our solution for schools is never just technical. In the centre
3927 are always the people who are going to use the software. From the very
3928 beginning of the planning for a school, we tell the schools head that
3929 they are paying us not only for a technical solution for their school,
3930 they also pay us for leading all the communication processes
3931 needed. If they do not want that, we are not working with them because
3932 we cannot give a guarantee for the quality of our work then.
</li
>
3934 <li
>Another focus lies in the training of teachers and students in
3935 co-administrating the IT-System at their school. They start getting in
3936 contact with the Skolelinux / Debian Edu community and they get the
3937 offer to become more and more independent from us.

3960 <p
>I sommer (
2012-
07-
23) hadde Fremover et oppslag om at Narvik
3961 kommune hadde spart mellom
10 og
20 millioner kroner de siste årene på
3962 å bruke Skolelinux på sine skoler. Harstad har også tatt i bruk
3963 Skolelinux på alle sine skoler. Som tidligere Ballangsværing gledet
3964 det meg stort å se at skoleløsningen vi har utviklet siden
2001 tas i
3965 bruk i området der jeg vokste opp, og dermed bidrar til en bedre og
3966 billigere skolehverdag.
</p
>
3968 <p
>Skolelinux er en komplett IT-løsning for elevnettverket på en
3969 skole, med både nettverkstjenester og løsning for elevmaskiner med
3970 pedagogisk programvare, som tillater en å øke levetiden på en
3971 datamaskin i skolen med mange år. En undersøkelse publisert i mars
3972 2012 viste at de
56 norske skolene som har offentliggjort at de bruker
3973 Skolelinux eller annen Linuxutgave hadde
36% større PC-tetthet enn
3974 landsgjennomsnittet, når en ser på tall rapportert til Grunnskolens
3975 Informasjonssystem. I følge Paul Reidar Løsnesløkken, IKT-konsulent i
3976 Nord-Odal, fungerer datamaskiner godt til de er
8 til
10 år gamle.
</p
>
3978 <p
>I høst (
2012-
09-
29) fortalte Fremover hvordan Ballangen kommune har
3979 opparbeidet seg
20 millioner i underskudd og nok havner på Robek-lista
3980 fra nyttår. Kanskje Ballangen også burde ta i bruk Skolelinux for å
3981 spare penger? Hvis kommunen mangler kompetanse lokalt på Linux finnes
3982 det kommersielle selskaper som tilbyr driftstjenester rundt
3983 Skolelinux, og jeg bør vel avsløre at jeg selv er involvert i et av
3984 dem, Skolelinux Drift AS. Kommunen kan dermed få hjelp hvis de ikke
3985 ønsker å bygge opp egen kompetanse.

4056 noe utviklerne er veldig glade for.

4058 <p

4059 skrevet om til å akseptere ord med bindestrek (f.eks. «e-post»). Litt
4060 over
10.000 slike ordformer er lagt til i orddatabasen. I tillegg er
4061 det kommet en del nye ord og rettelser rapportert inn av de frivillige
4062 som gjennomfører korrektur av orddatabasen i prosjektet. For å få
4063 fortgang i dette korrekturarbeidet er det fint med flere frivillige
4064 som kan bidra i prosjektet.

>After a long break in my row of interviews with people in the
4153 <a href=
"http://www.skolelinux.org/
">Debian Edu and Skolelinux
</a
>
4154 community, I finally found time to wrap up another. This time it is
4155 Giorgio Pioda, which showed up on the mailing list at the start of
4156 this year, asking questions and inspiring us to improve the first time
4157 administrators experience with Skolelinux. :) The interview was
4158 conduced in May, but I only found time to publish it now.
</p

4160 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p

4162 <p
>I have a PhD in chemistry but since several years I work as teacher
4163 in secondary (
15-
18 year old students) and tertiary (a kind of
"light
"
4164 university) schools. Five years ago I started to manage a Learning
4165 Management Service server and slowly I got more and more involved with
4166 IT.
3 years ago the graduating schools moved completely to Linux and I
4167 got the head of the IT for this. The experience collected in chemistry
4168 labs computers (for example NMR analysis of protein folding) and in
4169 the IT-courses during university where sufficient to start. Self
4170 training is anyway very important
</p
>
4172 <p
>I live in the Italian speaking part of Switzerland, and the
4173 <a href=
"http://www.spse.ch/
">SPSE school
</a
> (secondary) is a very
4174 special sport school for young people who try to became sport pro (for
4175 all sports, we have dozens of disciplines represented) and we are
4176 recognised by the Olympic Swiss Organisation.
4178 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4179 project?
</strong
></p
>
4181 <p
>Looking for Linux / Primary Domain Controller (PDC) I found it
4182 already several years ago. But since the system was still not
4183 Kerberized and since our schools relies strongly on laptops I didn
't
4184 use it. I plan to introduce it in the next future, probably for the
4185 next school year, since the squeeze release solved this security
4188 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4189 Edu?
</strong
></p
>
4191 <p
>Many. First of all there is a strong and living community that is
4192 very generous for help and hints. Chat help is crucial, together with
4193 the mailing list. Second. With Skolelinux you get an already well
4194 engineered platform and you don
't have to start to build up your PDC
4195 and your clients from GNU/scratch; I
've already done this once and I
4196 can tell it, it is hard. Third, since Skolelinux is a standard
4197 platform, it is way easier to educate other IT people and even if the
4198 head IT is sick another one could pick up the task without too much
4201 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
4202 Edu?
</strong
></p
>
4204 <p
>The only real problem I see is that it is a little too less
4205 flexible at client level. Debian stable is rocky and desirable, but
4206 there are many reasons that force for another choice. For example the
4207 need of new drivers for new PC, or the need for a specific OS for some
4208 devices that have specific software packages for another specific
4209 distribution (I have such a case for whiteboards that have only
4210 Ubuntu packages). Thus, I prepared compatibility packages educlient
4211 and eduroaming, hoping not to use them ;-)
</p
>
4213 <p
><strong
>Which free software do you use daily?
</strong
></p
>
4215 <p
>I have a Debian Stable PDC at school (Kerberos, NIS, NFS) with
4216 mixed Debian and Ubuntu clients. If you think that this triad
4217 combination is exotic... well I discovered right yesterday that
4218 <a href=
"http://moo.nac.uci.edu/~hjm/Perceus-Report.html
">Perceus
</a
>
4219 has the same...
</p
>
4221 <p
>For myself I run Debian wheezy/sid, but this combination is good
4222 only I you have enough competence to fix stuff for yourself, if
4223 something breaks. Daily I use texmacs, gnumeric, a little bit of R
4224 statistics, kmplot, and less frequently OpenOffice.org.
</p
>
4226 <p
><strong
>Which strategy do you believe is the right one to use to
4227 get schools to use free software?
</strong
></p
>
4229 <P
>I think that the only real argument that school managers
"hear
" is
4230 cost reduction. They don
't give too much weight on quality, stability,
4231 just because they are normally not open to change.
</p
>
4233 <p
>Students adapts very quickly to GNU/Linux (and for them being able
4234 to switch between different OS is a plus value); teachers and managers
4235 don
't.
</p
>
4237 <p
>We decided to move to Linux because students at our school have own
4238 laptop and we have the responsibility to keep the laptop ready to use;
4239 we were really unsatisfied with Microsoft since every Monday we had
20
4240 machine to fix for viral infections... With Linux this has been
4241 reduced to zero, since people installs almost only from official
4242 repositories. I think that our special needs brought us to Linux.
4243 Those who don
't have such needs will hardly move to Linux.

4258 vært vellykket.
</p

4260 <p
>Artikkelen med tittelen
"Narvik kommune bruker gratisprogram i
4261 skolen - Har spart millioner
", forteller om hvordan bruken av
4262 Skolelinux er en stor suksess i Narvik siden det ble tatt i bruk i
4263 2004. Her er noen fine sitater:
</p
>
4266 "- Skolelinux har spart kommunen for store pengesummer, millionbeløp,
4267 som de heller kan bruke på andre ting, sier IKT-konsulent Viggo
4271 <p
>Avisen forteller at de har fått tilgang til beregninger som viser
4272 at Narvik kommune har spart noe mellom
10 og
20 millioner kroner de
4273 siste
8 årene på å bruke Skolelinux, og fortsetter:
</p
>
4277 "Regnestykket tar høyde for sparte kostnader til lisenser som medfølger
4278 de alternative operativsystemene, lavere driftskostnader og lengre
4279 levetid på datautstyret. Totalt har Narvikskolen en maskinpark på
4280 1600 maskiner fordelt på de
11 skolene fra Skjomen i sør til Bjerkvik
4285 <p
>Viggo Fedreheim sier dette om hvor noe av gevinsten kommer fra:
</p
>
4288 "- Vi kan gjenbruke gamle maskiner i skolen som er for dårlig andre
4289 steder i kommunen der de ikke bruker Skolelinux. Levetiden på en
4290 datamaskin blir
3-
5 år lenger med Skolelinux. Vi kaller det for
4291 grønn IT, miljøvennlig IT.
"
4294 <p
>Her er det mulighet for flere kommuner å få et godt IT-system på
4295 skolene, hvis de er villige til å forsøke. De som ikke har kompetanse

12 years at
4372 the same school as
50% IT-manager and

4375 Norwegian I believe it

4376 in

'm not really a tech guy, I
4377 just like to study how humans and technology interact and that is my
4378 perspective when working with IT.
</p
>
4380 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4381 project?
</strong
></p
>
4383 I have followed the Skolelinux project for quite some time by
4384 now. Earlier I tested out the K12-LTSP project, which we used for some
4385 time, but I really like the idea of having a distribution aimed to be
4386 a complete solution for schools with necessary tools integrated. When
4387 K12-LTSP abandoned that idea some years ago, I started to look more
4388 seriously into Skolelinux instead.
4390 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4391 Edu?
</strong
></p
>
4393 The big point of Skolelinux to me is that it is a complete
4394 distribution, ready to install. It has LDAP-support, MS Windows
4395 integration tools and so forth already configured, saving an
4396 administrator a lot of time and headache. We were using another Linux
4397 based thin-client system called Thinlinc, that has served us very
4398 well. But that Skolelinux is based on VNC and LTSP, to me, is better
4399 when it comes to the kind of multimedia used in schools. That is
4400 showing videos from Youtube or educational TV. It is also easier to
4401 mix thin clients with workstations, since the user settings will be the
4402 same. In our VNC-based solution you had to
"beat around the bush
" by
4403 setting up a second, hidden, home-directory for user settings for the
4404 workstations, because they will be different from the ones used on the
4405 thin clients. Skolelinux support for diskless workstations are very
4406 convenient since a school today often need to use a class room
4407 projector showing videos in full screen. That is easily done with a
4408 small integrated media computer running as a diskless workstation. You
4409 have only two installs to update and configure. One for the thin
4410 clients and one for the workstations. Also saving a lot of time. Our
4411 old system was also based on Redhat and CentOS. They are both very
4412 nice distributions, but they are sometimes painfully slow when it
4413 comes to updating multimedia support and multimedia programs (even
4414 such as Gimp), leaving us with a bit
"oldish
" applications. Debian is
4417 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
4418 Edu?
</strong
></p
>
4420 <p
>Debian is a bit too quick when it comes to updating. As an example
4421 we use old HP terminals as thinclients, and two times already this
4422 year (
2012) the updates you get from the repositories has stopped
4423 sound from working with them. It
's a kernel/ALSA issue. So you have
4424 to be more careful properly testing the updates before you run them in
4425 a production environment. This has never happened with CentOS.
</p
>
4427 <p
>I also would like to be able to set my own domain-settings at
4428 install time. In Skolelinux they are kind of hard coded into the
4429 distribution, when it comes to LDAP and at least samba integration.
4430 That is more a cosmetic/translation issue, and not a real problem.
4431 Running MS Windows applications within the Skolelinux environment needs
4432 to be better supported. That is, running them seamlessly via RDP, and
4433 support for single-sign on. That will make the transition to free
4434 software easier, because you can keep the applications you really
4435 need. No support will make it impossible if you work in a school where
4436 some applications can
't be open source. As for us we really need to
4437 run Adobe InDesign in our journalist classes. We run a journalist
4438 education, and is one of the very few non university ones that is ok:d
4439 by Svenska journalistförbundet (Swedish journalist association). Our
4440 education gives the pupils the right of membership there, once they
4441 are done. This is important if you want to get a job.
</p
>
4443 <p
>Adobe InDesign is the program most commonly used in newspapers and
4444 magazines. We used Quark Express before, but they seem to loose there
4445 market to Adobe. The only
"equivalent
" to InDesign in the opensource
4446 world is Scribus, and its not advanced enough. At least not according
4447 to the teacher. I think it would be possible to use it, because they
4448 are not supposed to learn a program, they are supposed to learn how to
4449 edit and compile a newspaper. But politically at our school we are not
4450 there yet. And Scribus lacks a lot of things you find i InDesign.
</p
>
4452 <p
>We used even a windows program for sound editing when it comes to
4453 the radio-journalist part. The year to come we are going to try
4454 Audacity. That software has the same kind of limitations compared to
4455 Adobe Audition, but that teacher is a bit more open minded. We have
4456 tried Ardour also, but that instead is more like a music studio
4457 program, not intended for the kind of editing taking place in a radio
4458 studio. Its way to complex and the GUI is to scattered when you only
4459 want to cut, make pass-overs, add extra channels and normalise. Those
4460 things you can do in Audacity, but its not as easy as in Audition. You
4461 have to do more things manually with envelopes, and that is a bit old
4462 fashion and timewasting. Its also harder to cut and move sound from
4463 one channel to another, which is a thing that you do frequently
4464 because you often find yourself needing to rearrange parts of the
4465 sound file.
</p
>
4467 <p
>So, I am not sure we will succeed in replacing even Audition, but we
4468 will try. The problem is the students have certain expectations when
4469 they start an education towards a profession. So the programs has to
4470 look and feel professional. Good thing with radio, there are many
4471 programs out there, that radio studios use, so its not as standardised
4472 as Newspaper editing. That means, it does not really matter what
4473 program they learn, because once they start working they still have to
4474 learn the program the studio uses, so instead focus has to be to learn
4475 the editing part without to much focus on a specific software.

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

4479 <p
>Myself I
'm running Linux Mint, or Ubuntu these days. I use almost
4480 only open source software, and preferably Linux based. When it comes
4481 to most used applications its OpenOffice, and Firefox (of course ;)
4484 <p
><strong
>Which strategy do you believe is the right one to use to
4485 get schools to use free software?
</strong
></p
>
4487 <p
>To get schools to use free software there has to be good open
4488 source software that are windows based, to ease the transition. But
4489 it
's also very important that the multimedia support is working
4490 flawlessly. The problems with Youtube, Twitter, Facebook and whatever
4491 will create problems when it comes to both teachers and
4492 students. Economy are also important for schools, so using thin
4493 clients, as long as they have good multimedia support, is a very good
4494 idea. It
's also important that the open source software works even for
4495 the administration. It
's hard to convince the teachers to stick with
4496 open source, if the principal has to run Windows. It also creates a
4497 problem if some classes has to use Windows for there tasks, since that
4498 will create a difference in
"status
" between classes, so a good
4499 support for running windows applications via the thin client (Linux)
4500 desktop is essential. At least at our school, where we have mixed
4501 level of educations, from high-school to journalist-school.

>In the Debian Edu / Skolelinux project, we have realised that one
4521 of the major blockers for the project success is the purchasing skills
4522 in schools and municipalities. We provide what the happy users of
4523 Debian Edu / Skolelinux say they need and to a lower cost than the
4524 alternatives, and yet so few schools decide to use our solution. I

2000, der jeg måtte ha
"noe
4747 å gjøre
" under hjemturen over Atlanteren. Jeg kjøpte et par bøker om
4748 Linux i en bokhandel i New York og ble veldig fascinert. Etter
4749 hjemkomsten begynte jeg å jobbe på Ulsrud VGS, som naturfagslærer, men
4750 som IT-interessert ble jeg fort en del av den nye IT-satsningen som
4751 skulle løfte Ulsrud og gi skolen en bedre rykte. Vi hadde ganske
4752 mange maskiner, som gikk på Win98 og to servere som ble oppgradert til
4753 Win2000. Systemene var ustabil og dårlige. På leting etter noe
4754 bedre, uten å knekke ryggen økonomisk, kom jeg over
"Linux i Skolen
"
4755 og Skolelinux. Jeg tok kontakt med miljøet og en gjeng møtte opp på
4756 skolen, der vi gjorde en liten testinstallasjon. Etter et par år var
4757 ryggraden på skolen Linux (Skolelinux) og vi hadde flere hundre
4758 maskiner, både tynne klienter (gamle og nye), bærbare (Debian) og noen
4759 stasjonære (Win2000). På et tidspunkt var Ulsrud den råeste IT-skolen
4760 og det irriterte skolesjefen i Oslo, da de satset hardt på

4765 <p

4766 økonomiske. Det faktum at vi slapp å kjøpe masse nye lisenser og at
4767 vi kunne bruke gammel hardware. Alt i alt gjorde dette at vi sparte
4768 mye, men i stede for å bruke mindre på IT brukte vi det vi sparte på å
4769 skaffe mer hardware og på den måten gi det beste tilbudet i landet til
4770 våre elever. For oss som driftet var det himmel å ha et system som
4771 gikk å administrere sentralt og effektivt. Det var heller ikke så
4772 dumt at vi kunne
"låse
" maskinene mer effektivt enn vi kunne med
4773 Microsoft Windows, slik at vi slapp mye feil og problemer som ble
4774 forårsaket av
"kreative
" elever.

4788 HandBrake mye, og jeg har installert OpenWRT på flere av
4789 basestasjonene både hjemme og på jobben. I tillegg til det har jeg i
4790 flere år finansiert et prosjekt som heter

4799 man må oppfylle minimumskravene (ikke være best, men bra nok) og selge
4800 seg inn på hvor mye man sparer. Det betyr selvsagt at man sparer på
4801 lisenser, men også på driftsinnsats. Men nå når jeg ikke er en aktiv
4802 del av miljøet lenger hører jeg nesten ingen ting om fri programvare.
4803 Jeg stiller meg da spørsmålet om det har blitt stille rundt miljøet,
4804 eller om jeg kun så det tydeligere før når jeg var aktiv? Uansett er
4805 det for stille rundt Skolelinux-prosjektet nå.

4844 been used everyday inside Debian Edu.

4865 <p

4868 laptops, netbooks, tablets, interactive white-boards, etc.
</p

4870 <p
>Also the range of ages of the students is very broad and you can
4871 not use the same solutions for primary schools and secondary or even
4872 universities. So different strategies are needed.

4874 <p
>But, looking at these differences, and looking back to the things
4875 we
've done and implemented, and the places were we have spent most of
4876 our forces, I think we should focus as much as possible in free
4877 multi-platform environments, using only standards tools, and moving
4878 more and more to Internet or network solutions that could be deployed
4879 using wireless. I think we
'll see more and more personal devices in
4880 the schools, devices the students and teachers will take home with
4881 them, so the solutions must be able to be taken at home and continue
4882 working there.

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

20120311.nb.html
">Debian Edu
4893 based on Squeeze
</a
>, I came across some issues that should be
4894 addressed in the Wheezy release. I finally found time to wrap up my
4895 notes and provide quick summary of what I found, with a bit
4896 explanation.
</p
>
4900 <li
>We need to rewrite our package installation framework, as tasksel
4901 changed from using tasksel tasks to using meta packages (aka packages
4902 with dependencies like our education-* packages), and our installation
4903 system depend on tasksel tasks in
4904 /usr/share/tasksel/debian-edu-tasks.desc for package
4905 installation.
</li
>
4907 <li
>Enable Kerberos login for more services. Now with the Kerberos
4908 foundation in place, we should use it to get single sign on with more
4909 services, and avoiding unneeded password / login questions. We should
4910 at least try to enable it for these services:
4913 <li
>CUPS for admins to add/configure printers and users when using
4915 <li
>Nagios for admins checking the system status.
</li
>
4916 <li
>GOsa for admins updating LDAP and users changing their passwords.
</li
>
4917 <li
>LDAP for admins updating LDAP.
</li
>
4918 <li
>Squid for users when exam mode / filtering is active.
</li
>
4919 <li
>ssh for admins and users to save a password prompt.
</li
>
4921 </ul
></li
>
4923 <li
>When we move GOsa to use Kerberos instead of LDAP bind to
4924 authenticate users, we should try to block or at least limit access to
4925 use LDAP bind for authentication, to ensure Kerberos is used when it
4926 is intended, and nothing fall back to using the less safe LDAP bind
</li
>
4928 <li
>Merge debian-edu-config and debian-edu-install. The split made
4929 sense when d-e-install did a lot more, but these days it is just an
4930 inconvenience when we update the debconf preseeding values.
</li
>
4932 <li
>Fix partman-auto to allow us to abort the installation before
4933 touching the disk if the disk is too small. This is
4934 <a href=
"http://bugs.debian.org/
653305">BTS report #
653305</a
> and the
4935 d-i developers are fine with the patch and someone just need to apply
4936 it and upload. After this is done we need to adjust
4937 debian-edu-install to use this new hook.
</li
>
4939 <li
>Adjust to new LTSP framework (boot time config instead of install
4940 time config). LTSP changed its design, and our hooks to install
4941 packages and update the configuration is most likely not going to work
4944 <li
>Consider switching to NBD instead of NFS for LTSP root, to allow
4945 the Kernel to cache files in its normal file cache, possibly speeding
4946 up KDE login on slow networks.
</li
>
4948 <li
>Make it possible to create expired user passwords that need to
4949 change on first login. This is useful when handing out password on
4950 paper, to make sure only the user know the password. This require
4951 fixes to the PAM handling of kdm and gdm.
</li
>
4953 <li
>Make GUI for adding new machines automatically from sitesummary.
4954 The current command line script is not very friendly to people most
4955 familiar with GUIs. This should probably be integrated into GOsa to
4956 have it available where the admin will be looking for it..
</li
>
4958 <li
>We should find way for Nagios to check that the DHCP service
4959 actually is working (as in handling out IP addresses). None of the
4960 Nagios checks I have found so far have been working for me.
</li
>
4962 <li
>We should switch from libpam-nss-ldapd to sssd for all profiles
4963 using LDAP, and not only on for roaming workstations, to have less
4964 packages to configure and consistent setup across all profiles.
</li
>
4966 <li
>We should configure Kerberos to update LDAP and Samba password
4967 when changing password using the Kerberos protocol. The hook was
4968 requested in
<a href=
"http://bugs.debian.org/
588968">BTS report
4969 #
588968</a
> and is now available in Wheezy. We might need to write a
4970 MIT Kerberos plugin in C to get this.
</li
>
4972 <li
>We should clean up the set of applications installed by default.
4975 <li
>reduce the number of chemistry visualisers
</li
>
4976 <li
>consider dropping xpaint
</li
>
4977 <li
>and probably more?
</li
>
4978 </ul
></li
>
4980 <li
>Some hardware need external firmware to work properly. This is
4981 mostly the case for WiFi network cards, but there are some other
4982 examples too. For popular laptops to work out of the box, such
4983 firmware need to be installed from non-free, and we should provide
4984 some GUI to do this. Ubuntu already have this implemented, and we
4985 could consider using their packages. At the moment we have some
4986 command line script to do this (one for the running system, another
4987 for the LTSP chroot).
</li
>
4990 <li
>In Squeeze, we provide KDE, Gnome and LXDE as desktop options. We
4991 should extend the list to Xfce and Sugar, and preferably find a way to
4992 install several and allow the admin or the user to select which one to
4995 <li
>The golearn tool from the goplay package make it easy to check out
4996 interesting educational packages. We should work on the package
4997 tagging in Debian to ensure it represent all the useful educational
4998 packages, and extend the tool to allow it to use packagekit to install
4999 new applications with a simple mouse click.
</li
>
5001 <li
>The Squeeze version got half a exam solution already in place,
5002 with the introduction of iptable based network blocking, but for it to
5003 be a complete exam solution the Squid proxy need to enable
5004 filtering/blocking as well when the exam mode is enabled. We should
5005 implement a way to easily enable this for the schools that want it,
5006 instead of the
"it is documented
" method of today.
</li
>
5008 <li
>A feature used in several schools is the ability for a teacher to
5009 "take over
" the desktop of individual or all computers in the room.
5010 There are at least three implementations,
5011 <a href=
"italc.sourceforge.net/
">italc
</a
>,
5012 <a href=
"http://www.itais.net/help/en/
">controlaula
</a
> og
5013 <a href=
"http://www.epoptes.org/
">epoptes
</a
> and we should pick one of
5014 them and make it trivial to set it up in a school. The challenges is
5015 how to distribute crypto keys and how to group computers in one room
5016 and how to set up which machine/user can control the machines in a
5017 given room.
</li
>
5019 <li
>Tablets and surf boards are getting more and more popular, and we
5020 should look into providing a good solution for integrating these into
5021 the Debian Edu network. Not quite sure how. Perhaps we should
5022 provide a installation profile with better touch screen support for
5023 them, or add some sync services to allow them to exchange
5024 configuration and data with the central server. This should be
5025 investigated.

2010, Mike Gabriel showed up on the
5040 <a href=

</p

5046 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
5048 <p
>My name is Mike Gabriel, I am
38 years old and live near Kiel,
5049 Schleswig-Holstein, Germany. I live together with a wonderful partner
5050 (Angela Fuß) and two own children and two bonus children (contributed
5051 by Angela).
</p
>
5053 <p
>During the day I am part-time employed as a system administrator
5054 and part-time working as an IT consultant. The consultancy work
5055 touches free software topics wherever and whenever possible. During
5056 the nights I am a free software developer. In the gaps I also train in
5057 becoming an osteopath.
</p
>
5059 <p
>Starting in
2010 we (Andreas Buchholz, Angela Fuß, Mike Gabriel)
5060 have set up a free software project in the area of Kiel that aims at
5061 introducing free software into schools. The project
's name is
5062 "IT-Zukunft Schule
" (IT future for schools). The project links IT
5063 skills with communication skills.
</p
>
5065 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5066 project?
</strong
></p
>
5068 <p
>While preparing our own customised Linux distribution for
5069 "IT-Zukunft Schule
" we were repeatedly asked if we really wanted to
5070 reinvent the wheel. What schools really need is already available,
5071 people said. From this impulse we started evaluating other Linux
5072 distributions that target being used for school networks.
</p
>
5074 <p
>At the end we short-listed two approaches and compared them: a
5075 commercial Linux distribution developed by a company in Bremen,
5076 Germany, and Skolelinux / Debian Edu. Between
12/
2010 and
03/
2011 we
5077 went to several events and met people being responsible for marketing
5078 and development of either of the distributions. Skolelinux / Debian
5079 Edu was by far much more convincing compared to the other product that
5080 got short-listed beforehand--across the full spectrum. What was most
5081 attractive for me personally: the perspective of collaboration within
5082 the developmental branch of the Debian Edu project itself.
</p
>
5084 <p
>In parallel with this, we talked to many local and not-so-local
5085 people. People teaching at schools, headmasters, politicians, data
5086 protection experts, other IT professionals.
</p
>
5088 <p
>We came to two conclusions:
</p
>
5090 <p
>First, a technical conclusion: What schools need is available in
5091 bits and pieces here and there, and none of the solutions really fit
5092 by
100%. Any school we have seen has a very individual IT setup
5093 whereas most of each school
's requirements could mapped by a standard
5094 IT solution. The requirement to this IT solution is flexibility and
5095 customisability, so that individual adaptations here and there are
5096 possible. In terms of re-distributing and rolling out such a
5097 standardised IT system for schools (a system that is still to some
5098 degree customisable) there is still a lot of work to do here
5099 locally. Debian Edu / Skolelinux has been our choice as the starting
5102 <p
>Second, a holistic conclusion: What schools need does not exist at
5103 all (or we missed it so far). There are several technical solutions
5104 for handling IT at schools that tend to make a good impression. What
5105 has been missing completely here in Germany, though, is the enrolment
5106 of people into using IT and teaching with IT.
"IT-Zukunft Schule
"
5107 tries to provide an approach for this.
</p
>
5109 <p
>Only some schools have some sort of a media concept which explains,
5110 defines and gives guidance on how to use IT in class. Most schools in
5111 Northern Germany do not have an IT service provider, the school
's IT
5112 equipment is managed by one or (if the school is lucky) two (admin)
5113 teachers, most of the workload these admin teachers get done in there
5114 spare time.
</p
>
5116 <p
>We were surprised that only a very few admin teachers were
5117 networked with colleagues from other schools. Basically, every school
5118 here around has its individual approach of providing IT equipment to
5119 teachers and students and the exchange of ideas has been quasi
5120 non-existent until
2010/
2011.
</p
>
5122 <p
>Quite some (non-admin) teachers try to avoid using IT technology in
5123 class as a learning medium completely. Several reasons for this
5124 avoidance do exist.
</p
>
5126 <p
>We discovered that no-one has ever taken a closer look at this
5127 social part of IT management in schools, so far. On our quest journey
5128 for a technical IT solution for schools, we discussed this issue with
5129 several teachers, headmasters, politicians, other IT professionals and
5130 they all confirmed: a holistic approach of considering IT management
5131 at schools, an approach that includes the people in place, will be new
5132 and probably a gain for all.
</p
>
5134 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5135 Edu?
</strong
></p
>
5137 <p
>There is a list of advantages: international context, openness to
5138 any kind of contributions, do-ocracy policy, the closeness to Debian,
5139 the different installation scenarios possible (from stand-alone
5140 workstation to complex multi-server sites), the transparency within
5141 project communication, honest communication within the group of
5142 developers, etc.

5145 Edu?
</strong

5147 <p
>Every coin has two sides:
</p
>
5149 <p
>Technically:
<a href=
"http://bugs.debian.org/
311188">BTS issue
5150 #
311188</a
>, tricky upgradability of a Debian Edu main server, network
5151 client installations on top of a plain vanilla Debian installation
5152 should become possible sometime in the near future, one could think
5153 about splitting the very complex package debian-edu-config into
5154 several portions (to make it easier for new developers to
5155 contribute).
</p
>
5157 <p
>Another issue I see is that we (as Debian Edu developers) should
5158 find out more about the network of people who do the marketing for
5159 Debian Edu / Skolelinux. There is a very active group in Germany
5160 promoting Skolelinux on the bigger Linux Days within Germany. Are
5161 there other groups like that in other countries? How can we bring
5162 these marketing people together (marketing group A with group B and
5163 all of them with the group of Debian Edu developers)? During the last
5164 meeting of the German Skolelinux group, I got the impression of people
5165 there being rather disconnected from the development department of
5166 Debian Edu / Skolelinux.

5173 serious text writing I prefer LaTeX. I use gimp, inkscape, scribus for
5174 more artistic tasks. I run virtual machines in KVM and Virtualbox.

5179 is being integrated in Ubuntu

5213 <p

5214 Mathematics, and Computer Science (
"Informatik
"). During the past
12
5215 years (since
2000), I have been working for a comprehensive (and soon,
5216 also inclusive) school leading to all kind of general levels, such as
5217 O- or A-level (
"Abitur

><strong

</strong

5227 <p
>We had tried different Linux based school servers, when members of
5228 my local Linux User Group (LUG OWL) detected Skolelinux. I remember
5229 very well, being part of a party celebrating the Linux New Media Award
5230 (
"Best Newcomer Distribution
", also nominated: Ubuntu) that was given
5231 to Skolelinux at Linux World Exposition in Frankfurt,
2005 (IIRC). Few
5232 months later, I had the chance to join a developer meeting in Ulsrud
5233 (Oslo) and to hand out the award to Knut Yrvin and others. For more
5234 than
7 years, Skolelinux is part of our schools infrastructure, namely
5235 our main server (tjener), one LTSP (today without thin clients), and
5236 approximately
50 work stations. Most of these have the option to boot a
5237 locally installed Skolelinux image. As a consequence, I joined quite
5238 a few events dealing with free software or Linux, and met many Debian
5239 (Edu) developers. All of them seemed quite nice and competent to me,
5240 one more reason to stick to Skolelinux.

5245 <p
>Debian driven, you are given all the advantages of a community
5246 project including well maintained updates. Once, you are familiar with
5247 the network layout, you can easily roll out an entire educational
5248 computer infrastructure, from just one installation media. As only
5249 free software (FOSS) is used, that supports even elderly hardware,
5250 up-sizing your IT equipment is only limited by space (i.e. available
5251 labs). Especially if you run a LTSP thin client server, your
5252 administration costs tend towards zero.
</p
>
5254 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
5255 Edu?
</strong
></p
>
5257 <p
>While Debian
's stability has loads of advantages for servers, this
5258 might be different in some cases for clients: Schools with unlimited
5259 budget might buy new hardware with components that are not yet
5260 supported by Debian stable, or wish to use more recent versions of
5261 office packages or desktop environments. These schools have the
5262 option to run Debian testing or other distributions - if they have the
5263 capacity to do so. Another issue is that Debian release cycles
5264 include a wide range of changes; therefor a high percentage of human
5265 power seems to be absorbed by just keeping the features of Skolelinux
5266 within the new setting of the version to come. During this process,
5267 the cogs of Debian Edu are getting more and more professional,
5268 i.e. harder to understand for novices.

5327 intervjurunde av folkene bak Skolelinux-løsningen. Jeg har kjent Alf
5328 Tonny siden vi møttes som barn på påskefjellet i Ofoten, og ble
5329 gledelig overrasket da han dukket opp i Skolelinux-prosjektet etter å
5330 ikke ha sett noe til ham på mange år.

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

5334 <p
>Jeg er utdannet kokk av yrke, og har utøvet yrket i
12 år. Men
5335 etter at ryggen sa takk før seg, studerte jeg nettverksadministrasjon
5336 ved Næringsakademiet i Bergen årene
2008-
2009 slik at jeg kunne
5337 forfølge en av mine største interesser - data. Til daglig jobber jeg
5338 ved
<a href=

">Parken
5339 ungdomsskole
</a
> med å drifte skolens PC-er. Har også litt
5340 musikkundervisning.
</p
>
5342 <p
>Mitt mål er å bevisstgjøre musikklærene mulighetene med de frie
5343 programmene som finnes i Skolelinux, blant annet Rosegarden.
</p
>
5345 <p
>Har i mange år drevet med musikk og en av grunnen til at Rosegarden
5346 falt i smak for min del, var fordi denne fungere og ligner mest på
5347 Windows-programmet (cubase) jeg jobbet mye med da jeg i mine yngre
5348 dager var «Windows fanatiker». Ble introdusert til Linux av en kompis
5349 av meg for omtrent
14 år siden, og har bare blitt mer og mer glad i
5350 dette operativsystemet.
</p
>
5352 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
5354 <p
>Da jeg ble sykemeldt fra min gamle jobb, og måtte omskoleres,
5355 havnet jeg i
2007 sammen med Viggo Fedreheim på IKT-avdelingen i
5356 Narvik kommune, der ble jeg for første gang introdusert til
5357 Skolelinuxprosjektet.
</p
>
5359 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
5361 <p
>Skolelinux er enkelt å holde i drift og masse flotte programmer som
5362 geogebra, ktouch og kgeografi følger med pakken. Man kan ta i bruk
5363 gamle PC-er igjen, slik at skoler med dårlig råd får opp en brukbar
5364 PC-park. PC-er som er ca
6-
9 år gamle fungere tilfredstillende, bare
5365 de har
512 MB RAM eller mer.
</p
>
5367 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
5369 <p
>Ulempene er at noen av de pedagogiske programmene som lærene ønsker
5370 å bruke fungere dårlig med Linux. Mye pga. av at disse programmene
5371 blir ikke laget til Linuxbaserte operativsystemer.
</p
>
5373 <p
>Video- og bilde-redigering har dessverre en del mangler, mange av
5374 programmene har en tendens til og krasje. Det gjelder blant annet
5375 <a href=
"http://www.kdenlive.org/
">kdenlive
</a
> og
5376 <a href=
"http://www.openshotvideo.com/
">openshot
</a
>, for å nevne
5377 noen. De er ikke stabile nok. Når elevene kommer med filmsnutter de
5378 ønsker og jobbe med, så godtar ikke programmene filene, og når elevene
5379 jobber med redigering bare krasjer programmene uten forvarsel. Det er
5380 for vanskelig å få noe som bare fungerer ut av boksen her. Når en elev
5381 plugger inn et videokamera eller fotoapparat så er det alltid noe som
5382 ikke vil fungere. Programmene godtar ikke format, godtar ikke
5383 kameraet, osv., osv. Det er dessverre med på og dra ned en positiv
5384 opplevelse av bruk av fri programvare.
</p
>
5386 <p
>Man må ofte bruke flere en et video redigerings program før og få
5387 fullført en ønsket oppgave.
</p
>
5389 <p
>Eksempel:
</p
>
5391 <p
>Hvis det ene programmet ikke vil ta i mot videofilen klarer et
5392 annet det, men det programmet som klarer det kan ikke gjøre de samme
5393 oppgavene som det programmet som ikke ville ta i mot filen,
5394 Tilsvarende er det med foto, man må bruke flere programmer for å få
5395 et ferdig resultat. Til dags dato har jeg enda ikke funnet et video-
5396 og fotoprogram som kan tilfredstillende fullføre en oppgave.
</p
>
5398 <p
>Så man kan klare og fullføre en oppgave, men i verste fall må man
5399 innom
3-
4 programmer for å få det til. Så jeg har enda ikke til dags
5400 dato sett at et program fungere
100% til alt.
</p
>
5402 <p
>Det programmet jeg har best erfaring til er
5403 <a href=
"http://cinelerra.org/
">cinelerra
</a
>, men dessverre har det
5404 også tendenser og krasje av og til uten grunn.
</p
>
5406 Lydsystemet kan også være et mareritt. Konkret snakker jeg om når du
5407 bruker for eksempel et smartboard, så følger det med USB-lydkort på
5408 disse. Problemet ligger her i at systemet ikke vil velge rett
5409 lydkort, så man må inn med padevchooser for å sette opp PulseAudio
5410 til og velge at USB-lydkortet skal brukes. Det blir for tungvindt for
5411 lærene, de ønsker at ting skal fungere med en gang. (min løsning på
5412 det problemet ble at jeg måtte deaktivere lydkortet som fantes på
5413 maskinen) men da må man bestandig slå på smartboard-tavla.
5415 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
5417 Programmene jeg bruker mest av er: Rosegarden, jack, qsynth, audacity,
5418 k3b, openttd og libreoffice.
5420 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
5421 skoler til å ta i bruk fri programvare?
</strong
></p
>
5423 Jeg tror det må bevisstgjøring av Skolene til, dvs. reklamere høylytt
5424 og fortelle og vise de andre skolene at frie programvarer faktisk
5425 fungere. Jeg trur faktisk mange ikke vet at det finnes frie

>It has been a few busy weeks for me, but I am finally back to
5436 publish another interview with the people behind
5437 <a href=
"http://www.skolelinux.org/
">Debian Edu and Skolelinux
</a
>.
5438 This time it is one of our German developers, who have helped out over the
5439 years to make sure both a lot of major but also a lot of the minor
5440 details get right before release.
5442 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
5444 <p
>My name is Jürgen Leibner, I
'm
49 years old and living in
5445 Bielefeld, a town in northern Germany. I worked nearly
20 years as
5446 certified engineer in the department for plant design and layout of an
5447 international company for machinery and equipment. Since
2011 I
'm a
5448 certified technical writer (tekom e.V.) and doing technical
5449 documentations for a steam turbine manufacturer. From April this year
5450 I will manage the department of technical documentation at a
5451 manufacturer of automation and assembly line engineering.
</p
>
5453 <p
>My first contact with linux was around
1993. Since that time I used
5454 it at work and at home repeatedly but not exclusively as I do now at
5455 home since
2006.
</p
>
5457 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5458 project?
</strong
></p
>
5460 <p
>Once a day in the early year of
2001 when I wanted to fetch my
5461 daughter from primary school, there was a teacher sitting in the
5462 middle of
20 old computers trying to boot them and he failed. I helped
5463 him to get them booting. That was seen by the school director and she
5464 asked me if I would like to manage that the school gets all that old
5465 computers in use. I answered:
"Yes
".
</p
>
5467 <p
>Some weeks later every of the
10 classrooms had one computer
5468 running Windows98. I began to collect old computers and equipment as
5469 gifts and installed the first computer room with a peer-to-peer
5470 network. I did my work at school without being payed in my spare time
5471 and with a lot of fun. About one year later the school was connected
5472 to Internet and a local area network was installed in the school
5473 building. That was the time to have a server and I knew it must be a
5474 Linux server to be able to fulfil all the wishes of the teachers and
5475 being able to do this in a transparent and economic way, without extra
5476 costs for things like licence and software. So I searched for a
5477 school server system running under Linux and I found a couple of
5478 people nearby who founded
'skolelinux.de
'. It was the Skolelinux
5479 prerelease
32 I first tried out for being used at the school. I
5480 managed the IT of that school until the municipal authority took over
5481 the IT management and centralised the services for all schools in
5482 Bielefeld in December of
2006.

5484 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5485 Edu?
</strong
></p
>
5487 <p
>When I
'm looking back to the beginning, there were other advantages
5488 for me as today.
</p
>
5490 <p
>In the past there were advantages like:
</p
>
5494 <li
>I don
't need to buy it so it generates no costs to the school as
5495 they had little money to spent for computers and software.
</li
>
5497 <li
>It has a licence which grands all rights to use it without
5500 <li
>It was more able to fit all requirements of a server system for
5501 schools than a Microsoft server system, even if there are only Windows
5502 clients because of it
's preconfigured overall concept of being a
5503 infrastructure solution and community for schools, not only a
5506 <li
>I was able to configure the server to the needs of the
5509 </ul
></p
>
5511 <p
>Today some of the advantages has been lost, changed or new ones
5512 came up in this way:
</p
>
5516 <li
>Most schools here do have money to buy hardware and software
5519 <li
>They are today mostly managed from central IT departments which
5520 have own concepts which often do not fit to Debian Edu concepts
5521 because they are to close to Microsoft ideology.
</li
>
5523 <li
>With the Squeeze version of Debian Edu which now uses GOsa² for
5524 management I feel more able to manage the daily tasks than with the
5525 interfaces used in the past.
</li
>
5527 <li
>It is more modular than in the past and fits even better to the
5528 different needs.
</li
>
5530 <li
>The documentation is usable and gets better every day.
</li
>
5532 <li
>More people than ever before are using Debian Edu all over the
5533 world and so the community, which is an very important part I think,
5534 is sharing knowledge and minds.
</li
>
5536 <li
>Most, maybe all, of the technical requirements for schools are
5537 solved today by Debian Edu.
</li

5539 </ul
></p
>
5541 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
5542 Edu?
</strong
></p
>
5546 <li
>There are too few IT companies able to integrate Debian Edu into
5547 their product portfolio for serving schools with concepts or even
5548 whole municipality areas.
</li
>
5550 <li
>Debian Edu has beside other free and open software projects not
5551 enough lobbyists which promote free and open software to
5552 politicians.

5554 <li
>Technically there are no disadvantages I
'm aware of.

>
5556 </ul
></p
>
5558 <p
><strong
>Which free software do you use daily?
</strong
></p
>
5560 <p
>I use Debian stable on my home server and on my little desktop
5561 computer. On my laptop I use Debian testing/sid. The applications I
5562 use on my laptop and my desktop are Open/Libre-office, Iceweasel,
5563 KMail, DigiKam, Amarok, Dolphin, okular and all the other programs I
5564 need from the KDE environment. On console I use newsbeuter, mutt,
5565 screen, irssi and all the other famous and useful tools.
</p
>
5567 <p
>My home server provides mail services with exim, dovecot, roundcube
5568 and mutt over ssh on the console, file services with samba, NFS,
5569 rsync, web services with apache, moinmoin-wiki, multimedia services
5570 with gallery2 and mediatomb and database services with MySQL for me
5571 and the whole family. I probably forgot something.

>Da jeg googlet etter noe annet kom jeg tilfeldigvis over
5588 <a href=
"http://www.duo.uio.no/sok/work.html?WORKID=
58309">en
5589 hovedfagsoppgave
</a
> ved Universitetet i Oslo som diskuterer verdien
5590 av GPLs fire friheter for brukerne av IT-systemer. Jeg ble fascinert
5591 over det som presenteres der. Her er sammendraget:
</p
>
5593 <p
><blockquote
>
5595 <p
>Motivasjonen til å skrive denne oppgaven er en personlig undring
5596 over hvorfor det primært, og ofte eksklusivt, fokuseres på det
5597 økonomiske aspektet ved utredninger om fri programvare er et godt valg
5598 for det offentlige. Fri og produsenteid programvare bygger på
5599 fundamentalt forskjellige ideologier som kan ha implikasjoner utover
5600 økonomiske kostnader. Kunnskapskulturen som er med på å definere fri
5601 programvare er basert på åpenhet, og er en verdi i seg selv.
</p
>
5603 <p
>Oppgavens tema er programvarelisensen GPL og frihet. GPL-lisensiert
5604 programvare gir visse friheter i forhold til produsenteid
5605 programvare. Mitt spørsmål er om, og eventuelt i hvilken utstrekning,
5606 disse frihetene blir benyttet av ulike brukere og hvordan de
5607 manifesterer seg for disse brukerne. Sentrale spørsmål i oppgaven
5611 <li
>Hvordan fordeles handlekraft gjennom lisensieringen av programvaren?
</li
>
5612 <li
>Hvilke konsekvenser har programvarelisensen for de ulike brukere?
</li
>
5615 <p
>Fri programvare gir blant annet brukeren mulighet til å studere og
5616 modifisere kildekoden. Denne formen for frihet erverves gjennom
5617 kunnskap og krever at brukeren også er en ekspert. Hva skjer med
5618 frihetene til GPL når sluttbrukeren er en annen? Dette diskuteres i
5619 dialog med informantene.
</p
>
5621 <p
>Jeg har i denne oppgaven samlet inn intervjudata fra IKT-ansvarlige
5622 ved grunnskolene i Nittedal kommune, driftsansvarlig og IKT-veilederen
5623 for skolene i kommunen, samt IKT-koordinator for utdanning i Akershus
5624 fylkeskommune og bokmåloversettere av OpenOffice.org. Den empiriske
5625 delen av oppgaven er delt inn i to seksjoner; den første omhandler
5626 operativsystemet Skolelinux, den andre kontorprogrampakken
5627 OpenOffice.org.
</p
>
5629 <p
>Som vi vil se gir GPL lokal frihet og kontroll gjennom omfordeling
5630 av makt fra produsent til bruker. Brukerens makt analyseres gjennom
5631 begrepene brukermedvirkning og handlingsfrihet. Det blir også lagt
5632 vekt på strukturelle forhold rundt bruken av teknologi, og spesielt de
5633 økonomiske begrepene nettverkseksternaliteter, innlåsing og
5634 stiavhengighet. Dette er begreper av spesiell nytte når objektet som
5635 omsettes eller distribueres er et kommunikasjonsprodukt, fordi verdien
5636 til et slikt gode for en potensiell bruker avhenger av antall
5637 eksisterende brukere av godet. I tilknytning til denne problematikken
5638 inneholder oppgaven også en diskusjon rundt åpne standarder og
5641 <p
>Oppgaven konkluderer med at de «fire frihetene» som GPL-lisensen er
5642 laget for å beskytte er av avgjørende betydning for bruken av
5643 OpenOffice.org og Skolelinux, i Akershus fylkeskommune såvel som i
5644 skolene i Nittedal. Distribusjonen av handlekraft er ikke helt
5645 symmetrisk. Det er først og fremst de profesjonelle utviklerne i
5646 Skolelinux som direkte kan nyttiggjøre seg friheten til å endre kode,
5647 mens en sluttbruker som Nittedal kommune nyttiggjør seg den økonomiske
5648 friheten til å kunne distribuere programmene. Det er imidlertid også
5649 slik at ingen aktør klarer seg uten alle disse «frihetene».

5701 <p
>As every coin has two sides, the out-of-the-box philosophy has its
5702 downside, too. In my opinion, it is hard to modify and tweak the
5703 setup, if you need or want that. Further more, it is not easily
5704 possible to upgrade the system to a new release. It takes much too
5705 long after a Debian release to prepare the -Edu release, perhaps
5706 because the number of developers working on the core of the code is
5707 rather small and often busy elsewhere.

5714 <p

5722 <p
>One of the major problems is the vendor lock-in from top to bottom:
5723 Especially in combination with ignorant government employees and
5724 politicians, this works out great for the
"market-leader
". The school
5725 administration here in Baden-Wuerttemberg is occupied by that vendor.
5726 Documents have to be prepared in non-free, proprietary formats. Even
5727 free browsers do not work for the school administration. Publishers
5728 of school books provide software only for proprietary platforms.
</p
>
5730 <p
>To change this, political work is very important. Parts of the
5731 political spectrum have become aware of the problem in the last years.
5732 However it takes quite some time and courageous politicians to
'free
'
5733 the system. There is currently some discussion about
"Open Data
" and
5734 "Free/Open Standards
". I am not sure if all the involved parties have
5735 a clue about the potential of these ideas, and probably only a
5736 fraction takes them seriously. However it might slowly make free
5737 software and the philosophy behind it more known and popular.

5804 <a href=

">Skolelinux Drift AS
</a
> on speeding
5805 up a
<a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>
5806 Lenny installation using LTSP diskless workstations, and in the
5807 process I discovered something very surprising. The reason the KDE
5808 menu was responding slow when using it for the first time, was mostly
5809 due to the way KDE find application icons. I discovered that showing
5810 the Multimedia menu would cause more than
20 000 IP packages to be
5811 passed between the LTSP client and the NFS server. Most of these were
5813 NFS LOOKUP calls, resulting in a NFS3ERR_NOENT response. Because the
5814 ping times between the client and the server were in the range
2-
20
5815 ms, the menus would be very slow. Looking at the strace of kicker in
5816 Lenny (or plasma-desktop i Squeeze - same problem there), I see that
5817 the source of these NFS calls are access(
2) system calls for
5818 non-existing files. KDE can do hundreds of access(
2) calls to find
5819 one icon file. In my example, just finding the mplayer icon required
5820 around
230 access(
2) calls.
</p
>
5822 <p
>The KDE code seem to search for icons using a list of icon
5823 directories, and the list of possible directories is large. In
5824 (almost) each directory, it look for files ending in .png, .svgz, .svg
5825 and .xpm. The result is a very slow KDE menu when /usr/ is NFS
5826 mounted. Showing a single sub menu may result in thousands of NFS
5827 requests. I am not the first one to discover this. I found a
5828 <a href=
"https://bugs.kde.org/show_bug.cgi?id=
211416">KDE bug report
5829 from
2009</a
> about this problem, and it is still unsolved.
</p
>
5831 <p
>My solution to speed up the KDE menu was to create a package
5832 kde-icon-cache that upon installation will look at all .desktop files
5833 used to generate the KDE menu, find their icons, search the icon paths
5834 for the file that KDE will end up finding at run time, and copying the
5835 icon file to /var/lib/kde-icon-cache/. Finally, I add symlinks to
5836 these icon files in one of the first directories where KDE will look
5837 for them. This cut down the number of file accesses required to find
5838 one icon from several hundred to less than
5, and make the KDE menu
5839 almost instantaneous. I
'm not quite sure where to make the package
5840 publicly available, so for now it is only available on request.
</p
>
5842 <p
>The bug report mention that this do not only affect the KDE menu
5843 and icon handling, but also the login process. Not quite sure how to
5844 speed up that part without replacing NFS with for example NBD, and
5845 that is not really an option at the moment.

5880 Schweer, a valuable contributor to the project from Germany.
5882 <p

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

5884 <p
>I
've studied Mathematics at the university
'Ruhr-Universität
' in
5885 Bochum, Germany. Since
1981 I
'm working as a teacher at the school
5886 "<a href=
"http://www.westfalenkolleg-dortmund.de/
">Westfalen-Kolleg

</a
>", a second chance school. Here, young adults is given
5888 the opportunity to get further education in order to do the school
5889 examination
'Abitur
', which will allow to study at a university. This
5890 second chance is of value for those who want a better job perspective
5891 or failed to get a higher school examination being teens.
</p
>
5893 <p
>Besides teaching I was involved in developing online courses for a
5894 blended learning project called
'abitur-online.nrw
' and in some other
5895 information technology related projects. For about ten years I
've been
5896 teacher and coordinator for the
'abitur-online
' project at my
5897 school. Being now in my early sixties, I
've decided to leave school at
5898 the end of April this year.
</p

5900 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5901 project?
</strong
></p
>
5903 <p
>The first information about Skolelinux must have come to my
5904 attention years ago and somehow related to LTSP (Linux Terminal Server
5905 Project). At school, we had set up a network at the beginning of
1997
5906 using Suse Linux on the desktop, replacing a Novell network. Since
5907 2002, we used old machines from the city council of Dortmund as thin
5908 clients (LTSP, later Ubuntu/Lessdisks) cause new hardware was out of
5909 reach. At home I
'm using Debian since years and - subscribed to the
5910 Debian news letter - heard from time to time about Skolelinux. About
5911 two years ago I proposed to replace the (somehow undocumented and only
5912 known to me) system at school by a well known Debian based system:
5913 Skolelinux.
</p
>
5915 <p
>Students and teachers appreciated the new system because of a
5916 better look and feel and an enhanced access to local media on thin
5917 clients. The possibility to alter and/or reset passwords using a GUI
5918 was welcomed, too. Being able to do administrative tasks using a GUI
5919 and to easily set up workstations using PXE was of very high value for
5920 the admin teachers.
</p
>
5922 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5923 Edu?
</strong
></p
>
5925 <p
>It
's open source, easy to set up, stable and flexible due to it
's
5926 Debian base. It integrates LTSP out-of-the-box. And it is documented!
5927 So it was a perfect choice.
</p
>
5929 <p
>Being open source, there are no license problems and so it
's
5930 possible to point teachers and students to programs like
5931 OpenOffice.org, ViewYourMind (mind mapping) and The Gimp. It
's of
5932 high value to be able to adapt parts of the system to special needs of
5933 a school and to choose where to get support for this.

5970 <p
>Det er store forskjeller på skolenes digitale tilstand, viser
5971 undersøkelsen Monitor
2011 som er laget på oppdrag fra
5972 Kunnskapsdepartementet. Dette har ført til debatt om PC-tilgangen i
5973 skolen, og om de med Linux i skolen gjør det bedre bedre eller
5974 dårligere enn snittet i landet.
</p

5976 <p
>Nå har vi tallene. Skoler med Linux har
36% større PC-tetthet en
5977 landsgjennomsnittet. På spørsmål hvorfor skoler med Linux har større
5978 PC-tetthet, observerer Paul Reidar Løsnesløkken som er IKT-konsulent i
5979 Nord-Odal:
</p

5981 <p
><blockquote
>"Vi erfarer at klienter med Skolelinux har god funksjon
5982 til de er
8 til
10 år gamle. Dette er omtrent dobbelt så lenge som
5983 andre løsninger, og skolene får mer datautstyr for
5984 pengene.
"</blockquote
></p
>
5986 <p
>Undersøkelsen baserer seg på
56 skoler som har gjort det offentlig
5987 at de kjører Skolelinux eller annen Linux-utgave. De kan også ha PC-er
5988 med Windows i skolenettet. Når en sammenligner PC-tetthetene på
5989 skolene i kommunene Flora, Harstad, Kongsvinger, Narvik, Nittedal,
5990 Nord-Odal og Randaberg, er det i snitt
2,
28 elev pr. PC på skolene med
5991 Linux. På landsbasis er det
3.11 elev per PC i grunnskolen, i følge
5992 side
95 i Monitor-rapporten for

36% større
5993 PC-tetthet i skoler med Linux.

5999 godt over
100 skoleaktuelle programmene laget for læring. De fleste
6000 programmene er oversatt til over
50 språk. Elevene skal også kunne
6001 studere alle sider av dataprogrammene. Derfor følger også kildekode
6002 med. Elever med interesse kan lære av eksperter som har laget
6003 systemet. Dette med enkelt programmering i læreprogram som KTurtle,
6004 til profesjonelle verktøy som Qt Creator eller Java.

6006 <p
>Skolelinux er laget for sentralisert drift, der alt teknisk
6007 administrasjon av alle skolene kan gjøres sentralt fra kommunehuset
6008 eller sentralt i en region. F.eks. drifter to-tre personer
70.000
6009 skoledatamaskiner på
200 skoler i delstaten Extremadura i
6010 Spania. Etter velykket bruk av Debian Edu i skolen, legger delstaten
6011 over til Debian på
40.000 datamaskiner i administrasjonen. Det er idag

6064 Win Vista) – assistenter har tilgang til egne. Vi benytter Fronter i
6065 det daglige arbeidet. Vi har ca
90 elevmaskiner som fungerer til
6066 daglig opp mot Linux server (XFCE) som driftes av
6067 <a href=
"http://www.bzz.no/
">BzzWare AS
</a
> via nett. Maskinparken
6068 består kun av brukt utstyr for elevene – og noe av dette begynner å
6069 bli vel gammelt selv som halvtykke klienter.
</p

6071 <p
><strong
>Hvordan kom du i kontakt med
6072 Skolelinux-prosjektet?
</strong
></p
>
6074 <p
>Vi kom første gang i kontakt med Skolelinux rundt
1997. Den gang
6075 var det oppstart-disketter i hver maskin, ikke mulighet for lyd og
6076 video, gamle nettverkskort og mye plundring. Vi hadde en ihuga
6077 forelder med som pådriver, forsker og inspirator for hele opplegget.
6078 Selv ante jeg knapt at Skolelinux fantes, men han var av den
6079 utforskende typen, og fikk både meg og skolelederen i trua på at dette
6080 var ting som kunne fungere. Etter dette har det gått gradvis
6081 framover; flere maskiner er hentet inn gjennom bl.a
6082 <a href=
"http://www.greentech.no/
">Greentech
</a
> og utrangert utstyr
6083 fra høgskole / Avinor og private givere. Når maskinene ble for trege
6084 for nye Windows-versjoner, sto vi klare til å putte dem i nettverket
6085 vårt. Dette betyr at vi i dag har
1:
1 dekning av maskiner på
6086 ungdomstrinnet og bedre enn
1:
2 på barnetrinnet. Dette er vi veldig
6087 fornøyd med, og vi kan ikke se for oss hverdagen som ville vært
6088 alternativet ved bruk av Windows med sine lisenser pr. Bruker/maskin.
6089 Da ville vi nok vært tilbake til
1-
2 maskiner pr klasserom med de
6090 negative konsekvenser det ville hatt for undervisningsformene våre. Vi
6091 kan ha en hel klasse i prosjektjobbing eller individuell jobbing
6092 samtidig – vi kan avholde tentamen og eksamen uten
6093 logistikkproblemer.
</p
>
6095 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6097 Hvor skal jeg begynne... Stabiliteten er et nøkkelord - det bare
6098 virker. Har du først fått en server med Skolelinux opp og gå, så må
6099 det en maskinarefeil eller sabotasje til for å stoppe den. Det at man
6100 kan bruke eldre maskiner som normalt sett ville gått på dynga, er også
6101 glimrende - billig for skoler med dårlig økonomi og bra for miljøet
6102 siden vi gjenbruker utstyr i stedet for å skaffe nytt. Vi ville aldri
6103 hatt mulighet til å operere med det maskinantallet vi har pr i dag
6104 hvis det ikke var for Skolelinux - så tilgjengelighet er et annet
6105 nøkkelord. Et tredje moment er sikkerhet og brukertilgang. Alle
6106 brukerer opererer med egne brukernavn og passord, samt egne
6107 brukerområder som kan tilpasses for både enbrukertilgang og for
6108 samarbeid med andre.
6110 Elever har godt av å se at det finnes andre alternativer enn de som
6111 storindustrien selger på lisensbasis - på den måten trenes de opp til
6112 å se flere muligheter og å foreta valg ut fra flere opsjoner.
6114 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6116 <p
>Ulempene med Skolelinux er nok utbredelsen og mangelen på kjennskap
6117 til dette i skolenorge. De som skal ta økonomiske avgjørelser rynker
6118 på nesen og vil gå for det kjente og «sikre» selv om det koster mye
6119 mer. Man får rett og slett litt hetta av å ikke kunne noe – og unngår
6120 dette for enhver pris.
</p
>
6122 <p
>I tillegg er mye av linux-systemet administrert av tekstkommandoer
6123 og er lite intuitiv/visuell for oss som ikke er «inne i»
6124 kildekodene». Så problemet er nok mye godt at de som
6125 utarbeider/drifter Skolelinux ikke helt klarer å sette seg ned på
6126 skoleadministratorens nivå når det gjelder problemer og
6127 utfordringer. Men dette er nok en utfordring alle administratorer
6128 sliter med uansett OS.
</p
>
6130 <p
>Derfor har vi valgt å støtte oss til BzzWare AS for assistanse i
6131 drifta slik at jeg har kunnet konsentrere meg mer om kabling, skifting
6132 av komponenter, veiledning av lærere og elever, vedlikehold av
6133 skrivere og annen daglig drift.
</p
>
6135 <p
>Elevene mestrer Skolelinux helt fint. Så lenge Internett
6136 (Iceweasel) og Libreoffice (Openoffice) fungerer er
90% av
6137 skolehverdagen velfungerende. I tillegg brukes jo en del av den
6138 pedagogiske programpakken bla. i forhold til matematikk og geografi,
6139 men det er såpass mye bra på nett om dagen, så disse programmene er
6140 mer som krydder å regne.
</p
>
6142 <p
>Jeg skulle ønske neste versjon av Skolelinux kunne komme litt
6143 mindre stappet med programmer, for halvparten blir aldri brukt, eller
6144 fungerer ikke uansett. Hva med et pedagogisk panel av lærere/IKT
6145 ansvarlige som kunne sagt: disse programmene skal være standard, så
6146 får resten være slike man kan legge til ved behov – det kan lett bli
6147 en jungel å bevege seg i.
</p
>
6149 <p
>Jeg ønsker meg også en mer grafisk versjon av
6150 <a href=
"http://bzz.no/lwat/trac/trac.cgi
">Lwat
</a
> hvor man kan krysse
6151 ut de som f.eks ikke skal ha internett-tilgang en dag pga
6152 eksamen/tentamen, samt en noe enklere brannmurløsning hvor man kan
6153 stenge for en del (få) sider på en enkel måte. Jeg liker godt
6154 Skolelinux sin ideologi om at filteret skal trenes i hodet på eleven –
6155 men av og til skulle jeg ønske at f.eks Facebook og Youtube kunne vært
6156 koblet vekk en periode for å få bedre utnyttelse av tid og
6157 ressurser. Disse to nettstedene er nok mye av årsaken til at mange
6158 lærere holder igjen databruken noe mer enn man kunne ønske.
</p
>
6160 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
6162 Jeg benytter nesten bare fri programvare til daglig. LibreOffice,
6163 Iceweasel (Firefox), Thunderbird til e-post og Gimp til
6164 bildebehandling. Vi har PHP-Nuke-oppsatt hjemmeside. Det eneste som
6165 jeg ikke har fått helt til enda er videoredigering - her må man vel
6166 innrømme at Mac er hakket over, men da er vi igjen over på å se hva
6167 som egner seg best, og ta valg ut fra det. Folk flest lever i
6168 villfarelsen om at regneark HETER Excel og tekstbehandling HETER
6169 Word. Dette er en misforståelse som jeg bruker mye energi på å
6170 diskutere og
"åpne sinn
" på Microsoft-slaver. Dessverre er det mange
6171 IKT-ansvarlige som også har låst seg på at det eneste saliggjørende er
6172 Bill G sine produkter.
6174 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
6175 skoler til å ta i bruk fri programvare?
</strong
></p
>
6177 <p
>For å komme lenger i utbredelsen av Skolelinux tror jeg det må mer
6178 fram i nasjonale medier, samt komme bedre fram hva økonomien i dette
6179 valget vil være – samt mulighetene. Fri programvare er en berikelse og
6180 gjør oss i stand til å utføre arbeidet i skolen uten å måtte legge
6181 igjen tusener på tusener i Bill Gates lomme.. Få ETT nettsted med
6182 forståelig veiledning av installasjon/oppgradering og ETT forum med
6183 konkrete feilrettinger og problemer, så tror jeg vi kunne kommet et
6184 par skritt framover. Ellers tror jeg bare at ildsjelene må fortsette å
6185 skinne – kanskje flere enn oss følger etter på veien.

>Den siste uka har det vært en del skriverier om hvor store
6220 forskjeller det er mellom skolene når det gjelder digital kompetanse.

"http://www.digi.no/

">oppslaget
6223 i Digi
</a
>. Diskusjonen fikk meg til å bli litt nysgjerrig på om
6224 Linux-skoler har større PC-tettet enn snittet i landet. Grunnlaget
6225 for diskusjonen har vært undersøkelsen
6226 <a href=
"https://iktsenteret.no/ressurser/monitor-
2011-skolens-digitale-tilstand
">Monitor
6227 2011</a
>, som bruker informasjon fra
6228 <a href=
"https://www.wis.no/gsi
">Grunnskolens Informasjonssystem
</a
>
6229 (GSI). GSI-data kan lastes ned fra web og jeg lastet ned en Excel-fil
6230 (intet åpen standard-valg tilgjengelig) med navn på alle skoler,
6231 hvilke kommune de befinner seg i og hvor mange elever pr. elev-PC de
6232 har rapportert inn. For å få en ide om svaret trenger jeg deretter å
6233 vite hvilke skoler i landet som bruker Linux, slik at jeg kan slå dem
6234 opp i GSI og finne ut hvor stor PC-tetthet de har.
</p
>
6236 <p
>Jeg vet om skoler i Balsfjord, Flora, Harstad, Kongsvinger, Narvik,
6237 Nittedal, Nord-Odal, Randaberg og Sunndal som bruker Skolelinux eller
6238 andre Linux-varianter. Jeg tror det er flere enn de
56 skolene jeg
6239 har klart å identifisere de siste dagene, men har ikke klart å få det
6240 bekreftet med offentlige kilder.
</p
>
6242 <p
>Monitor
2011-rapporteres side
95 forteller at det
"ifølge GSI
6243 (
20120-
2011) er det
3,
11 elever per datamaskin når vi tar med alle
6244 grunnskoler (
1.-
10.trinn)
". For de
56 Linux-skolene jeg har klart å
6245 koble mot informasjon i GSI er det
2,
28 elever per elevdatamaskin,
6246 hvilket betyr at det er
36% høyere PC-tetthet på Linux-skoler enn
6247 landsgjennomsnittet. Linux-skolen med høyest tettet blant de jeg har
6248 notert -skole er Flora ungdomsskule i Flora kommune med
0.82 elev
6249 pr. PC (
482 elever,
588 elevdatamaskiner).
</p
>
6251 <p
>Skolelinux gir datamaskiner lengre levetid, og en kan dermed få
6252 flere operative datamaskiner for samme budsjett, i tillegg til en
6253 rekke andre fordeler. Kan det være forklaringen på forskjellen?
</p
>
6255 <p
>Tallene må tas med en liten klype, da GSI ser ut til å ha endel
6256 feilføringer. Jeg synes i hvert fall en skole med
423 elever og
9
6257 elevmaskiner ser mistenkelig ut. Eller en skole med
346 elever,
0
6258 elevmaskiner, som er et annet ekstremt eksempel jeg fant.

6278 <p
>I teach ICT part time at the Rudolf Steiner School in Kings
6279 Langley, near London, UK. Previously I worked as a technical
6280 author/trainer while my children attended the school, and I also
6281 contributed to the Schoolforge UK community with the aim of
6282 encouraging UK schools to adopt free/open source software. Five or six
6283 years ago we had about
50 schools interested in some way, but we
6284 weren
't able to convert many of them into sustainable
6285 installations.
</p

6287 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
6288 project?
</strong
></p

6290 <p
>Skolelinux had two representatives at an early Edubuntu meeting in
6291 London which I attended. However at that time our school network had
6292 just been installed using CentOS, LTSP
4 and GNOME. When LTSP
5 came
6293 along we switched to Edubuntu thin client servers so now we have a
6294 mixed environment which includes Windows PCs and student laptops, as
6295 well as their MacBooks and iPads. However, the proprietary systems
6296 have always been rather problematic, and we never built a GUI for the
6297 LDAP server, so when I discovered Skolelinux is configured for all
6298 these things we decided to try it.

6303 <p
>By far the biggest advantage is the Debian Edu community. Apart
6304 from that I have always believed in the same
"sustainable computing
"
6305 goals that Skolelinux is built on: installing Linux on computers which
6306 would otherwise be thrown away, to provide a reliable, secure and
6307 low-cost IT environment for schools. From my own experience I know
6308 that a part-time person can teach and manage a network of about
25
6309 Linux computers, but it would take much more of my time if we had
6310 proprietary software everywhere.

6315 <p

'm just finding out who
's who in the community and
6316 how you
're organised, and what your procedures are for dealing with
6317 various things such as editing manual pages and so-on. The only
6318 English language mailing list seems to be for developers as well as
6319 users, so my inbox needs heavy pruning each day!

6323 <p
>Besides the software already mentioned at school we use Samba,
6324 OpenLDAP, CUPS, Nagios and Dansguardian for the network, and on the
6325 desktops we have LibreOffice, Firefox, GIMP and Inkscape. At home I
6326 use Ubuntu and an Android
4 eePad Transformer (but I
'm not sure if
6327 that counts...)
</p

6329 <p
><strong
>Which strategy do you believe is the right one to use to
6330 get schools to use free software?
</strong
></p
>
6332 <p
>That
's a tough question! For very many years UK schools installed
6333 and taught only proprietary software, so that at the highest levels
6334 the notion of
"computer
" means simply
"proprietary office
6335 applications
". However, schools today are experiencing budget
6336 constraints, and many are having to think hard about upgrading Windows
6337 XP. At the same time, we have students showing teachers how to use
6338 iPads, MacBooks and Android, so the choice of operating system is no
6339 longer quite so automatic. What is more, our government at last
6340 realised that we need people with programming skills, so they
're
6341 putting coding back in the curriculum! And it
's encouraging that the
6342 first
10,
000 Raspberry Pi units sold out in
2 hours.
</p

6344 <p
>I don
't really know what strategy is going to get UK schools to use
6345 free software, but building an active community of Skolelinux/Debian
6346 Edu users in this country has to be part of it.

6356 it is important to make it both easy to contribute and to keep the
6357 translated versions in sync. To do this we have come up with what we
6358 believe is a very efficient work flow.
</p
>
6362 <li
>The documentation is written in a
6363 <a href=
"http://moinmo.in

</a
> (see for example
6364 <a href=
"http://wiki.debian.org/DebianEdu/Documentation/Squeeze

6366 docbook XML.
</li
>
6368 <li
>This docbook document is given to po4a to extract a gettext style
6369 .pot file with the content, which in turn is used to create .po files
6370 with the translated text.
</li
>
6372 <li
>The .po files are given to translators, and they can always tell
6373 which part of the original wiki document is new or changed. They can
6374 use their normal translation tools like lokalize or poedit to write
6375 the translation. There is even a system in place to handle translated
6378 <li
>The translated .po files are combined with the original docbook
6379 XML document using po4a to create a translated docbook document.
</li
>
6381 <li
>The final step is to use all the generated docbook files and
6382 create PDF and HTML version of the original and translated documents.
</li
>
6386 <p
>This setup work very well, but have a few issues. The biggest
6387 issue is that
<a href=
"http://moinmo.in/DocBook
">the docbook support
6388 we use in moinmoin
</a
> is not actively maintained. The docbook
6389 support is also buggy, and our build system contain workarounds to
6390 make sure the generated docbook is usable despite these bugs.

6449 <p
>Jeg hørte om det først når jeg jobbet i Redpill Linpro. Men jeg
6450 har også en datter som går på en friskole, som også bruker Skolelinux.
6451 Som kjent har ikke friskoler de samme økonomiske rammebetingelsene som
6452 offentlige skoler, så for dem var det det absolutt beste alternativet.
6453 De anser også Skolelinux som et stabilt system, som bare går og går (i
6454 motsetning til det lille Windows-baserte nettverket de har på
6455 admin-siden).

6459 <p
>Sentralisert drift av tynne og diskløse arbeidsstasjoner. Således
6460 lydløse og raskere arbeidsstasjoner som er bedre i klasserommet.
6461 Lengre levetid på PC
'er. Store besparelser på maskinvare og drift. Og
6462 så klart fjerning av alle lisenskostnader. Personlig synes jeg også at
6463 mange av programmene er bedre enn alternativene. Men dette er ofte en
6464 smakssak og avhengig om man må ha det man er vant til fra før.

6469 kompatibilitet med arbeidsstasjoners/bærbare maskiner sine
6470 nettverksdrivere eller skjermkort. Men dette løser vi i skolene ved
6471 standardisering. Ellers er det få, om nesten ingen, av de kjente
6472 maskinvare / infrastruktur leverandørene til fylkes- / kommuner som
6473 tilbyr denne plattformen. Skal dette endre seg så må kommunene selv
6474 sette slike krav til leverandørene.

6486 <p
>Fortsette å presentere flere av de gode eksemplene hvor Debian Edu
6487 / Skolelinux brukes i kommuner og enkeltskoler. Vi må få bedre frem
6488 at det er mulig tilknytte både Windows og Mac klienter på denne
6489 plattformen (selv om det vil øke driftskostnadene). Dette gjøres
6490 mange steder. Spesielt er det mange lærere som ønsker å bruke
6491 Windows/Mac-bærbare, gjerne som sin private PC også. Det er også mulig
6492 for kommunen å integrere med Active Directory i stedet for OpenLDAP
6493 som kommer med ut av boksen (selv om også dette øker kostnadene).
6494 Dette vil muligens bidra til å fjerne noe motstand hos noen
6495 potensielle brukere / driftpersonell for å ta i bruk noe
6496 nytt. Fremveksten av mobile brukere og nettbrett går i vår favør.
6497 Brukerne blir kjent og vant til flere nye operativsystemer /
6498 brukergrensesnitt. Så utviklerfellesskapet bør jobbe videre med å
6499 integrere flere nye klienttyper, som ultra lav-kostklienter og
6500 nettbrett (blant annet fri programvare-alternativet

>Inspired by
<a href=
"http://raphaelhertzog.com/tag/interview/
">the
6532 interview series
</a
> conducted by Raphael, I started a Norwegian
6533 interview series with people involved in the Debian Edu / Skolelinux
6534 community. This was so popular that I believe it is time to move to a
6535 more international audience.
</p
>
6537 <p
>While
<a href=
"http://www.skolelinux.org/
">Debian Edu and
6538 Skolelinux
</a
> originated in France and Norway, and have most users in
6539 Europe, there are users all around the globe. One of those far away
6540 from me is Nigel Barker, a long time Debian Edu system administrator
6541 and contributor. It is thanks to him that Debian Edu is adjusted to
6542 work out of the box in Japan. I got him to answer a few questions,
6543 and am happy to share the response with you. :)
6546 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
6548 <p
>My name is Nigel Barker, and I am British. I am married to Yumiko,
6549 and we have three lovely children, aged
15,
14 and
4(!) I am the IT
6550 Coordinator at Hiroshima International School, Japan. I am also a
6551 teacher, and in fact I spend most of my day teaching Mathematics,
6552 Science, IT, and Chemistry. I was originally a Chemistry teacher, but
6553 I have always had an interest in computers. Another teacher teaches
6554 primary school IT, but apart from that I am the only computer person,
6555 so that means I am the network manager, technician and webmaster,
6556 also, and I help people with their computer problems. I teach python
6557 to beginners in an after-school club. I am way too busy, so I really
6558 appreciate the simplicity of Skolelinux.
</p
>
6560 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
6561 project?
</strong
></p
>
6563 <p
>In around
2004 or
5 I discovered the ltsp project, and set up a
6564 server in the IT lab. I wanted some way to connect it to our central
6565 samba server, which I was also quite poor at configuring. I discovered
6566 Edubuntu when it came out, but it didn
't really improve my setup. I
6567 did various desperate searches for things like
"school Linux server
"
6568 and ended up in a document called
"Drift
" something or other. Reading
6569 there it became clear that Skolelinux was going to solve all my
6570 problems in one go. I was very excited, but apprehensive, because my
6571 previous attempts to install Debian had ended in failure (I used
6572 Mandrake for everything - ltsp, samba, apache, mail, ns...). I
6573 downloaded a beta version, had some problems, so subscribed to the
6574 Debian Edu list for help. I have remained subscribed ever since, and
6575 my school has run a Skolelinux network since Sarge.
</p
>
6577 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
6578 Edu?
</strong
></p
>
6580 <p
>For me the integrated setup. This is not just the server, or the
6581 workstation, or the ltsp. Its all of them, and its all configured
6582 ready to go. I read somewhere in the early documentation that it is
6583 designed to be setup and managed by the Maths or Science teacher, who
6584 doesn
't necessarily know much about computers, in a small Norwegian
6585 school. That describes me perfectly if you replace Norway with
6588 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
6589 Edu?
</strong
></p
>
6591 <p
>The desktop is fairly plain. If you compare it with Edubuntu, who
6592 have fun themes for children, or with distributions such as Mint, who
6593 make the desktop beautiful. They create a good impression on people
6594 who don
't need to understand how to use any of it, but who might be
6595 important to the school. School administrators or directors, for
6596 instance, or parents. Even kids. Debian itself usually has ugly
6597 default theme settings. It was my dream a few years back that some
6598 kind of integration would allow Edubuntu to do the desktop stuff and
6599 Debian Edu the servers, but now I realise how impossible that is. A
6600 second disadvantage is that if something goes wrong, or you need to
6601 customise something, then suddenly the level of expertise required
6602 multiplies. For example, backup wasn
't working properly in Lenny. It
6603 took me ages to learn how to set up my own server to do rsync backups.
6604 I am afraid of anything to do with ldap, but perhaps Gosa will
6607 <p
><strong
>Which free software do you use daily?
</strong
></p
>
6609 <p
>Nowadays I only use Debian on my personal computers. I have one for
6610 studio work (I play guitar and write songs), running AV Linux
6611 (customised Debian) a netbook running Squeeze, and a bigger laptop
6612 still running Skolelinux Lenny workstation. I have a Tjener in my
6613 house, that
's very useful for the family photos and music. At school
6614 the students only use Skolelinux. (Some teachers and the office still
6615 have windows). So that means we only use free software all day every
6616 day. Open office, The GIMP, Firefox/Iceweasel, VLC and Audacity are
6617 installed on every computer in school, irrespective of OS. We also
6618 have Koha on Debian for the library, and Apache, Moodle, b2evolution
6619 and Etomite on Debian for the www. The firewall is Untangle.
</p
>
6621 <p
><strong
>Which strategy do you believe is the right one to use to
6622 get schools to use free software?
</strong
></p
>
6624 <p
>Current trends are in our favour. Open source is big in industry,
6625 and ordinary people have heard of it. The spread of Android and the
6626 popularity of Apple have helped to weaken the impression that you have
6627 to have Microsoft on everything. People complain to me much less about
6628 file formats and Word than they did
5 years ago. The Edu aspect is
6629 also a selling point. This is all customised for schools. Where is the
6630 Windows-edu, or the Mac-edu? But of course the main attraction is
6631 budget.The trick is to convince people that the quality is not
6632 compromised when you stop paying and use free software instead. That
6633 is one reason why I say the desktop experience is a weakness. People
6634 are not impressed when their USB drive doesn
't work, or their browser
6635 doesn
't play flash, for example.

>Many years ago, the
<a href=
"http://www.skolelinux.org/
">Skolelinux
6682 / Debian Edu project
</a
> initiated a student project to create a tool
6683 for making stop motion movies. The proposal came from a teacher
6684 needing such tool on Skolelinux. The project, called
"stopmotion
",
6685 was manned by two extraordinary students and won a school award and a
6686 national aware with this great project. The project was initiated and
6687 mentored by Herman Robak, and manned by the students Bjørn Erik Nilsen
6688 and Fredrik Berg Kjølstad. They got in touch with people at Aardman
6689 Animation studio and received feedback on how professionals would like
6690 such stopmotion tool to work, and the end result was and is used by
6691 animators around the globe. But as is usual after studying, both got
6692 jobs and went elsewhere, and did not have time to properly tend to the
6693 project, and it has been lingering for a few years now. Until last
6696 <p
>Last year some of the users got together with Herman, and moved the
6697 project to Sourceforge and in effect restarted the project under a new
6699 <a href=
"http://sourceforge.net/projects/linuxstopmotion/
">linuxstopmotion
</a
>.
6700 The name change was done to make it possible to find the project using
6701 Internet search engines (try to search for
'stopmotion
' to see what I
6702 mean). I
've been following
6703 <a href=

>Knut Yrvin her. Jobber i Nokia med å fremme rammeverket Qt og QML
6783 med tilhørende utviklerverktøy. Rollen er som leder av
6784 friprog-samfunn. I fjor var jeg med å legge om utviklingen av Qt til
6785 åpen forvaltning. På den måten kan alle som bidrar til Qt gjøre det
6786 på like vilkår. Nå er det

6788 1000 utviklere

6789 forvaltning er utviklingen av Qt mer åpen enn Linux-kjernen.

>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
6793 <p
>Jeg var en av initiativtagerne til Skolelinux i
2001. Skolene slet
6794 med både utstyr og Internett-tilgang. De klarte ikke å møte
6795 forventningene til data i skolen. Driften av PC-ene var uholdbar. Som
6796 regel hadde rektor pekt ut en ivrig lærer til å passe på PC-ene,
6797 gjerne naturfaglæreren. Mange lærere jobbet mye ubetalt overtid for å
6798 vedlikeholde
30-
40 datamaskiner på hver sin skole. Med
300 elever og
6799 lærere som brukere, blir det fort mye mer arbeid enn de
4-
8 timene de
6800 kunne bruke på PC-drift. Skolene hadde kun en femtedel av
6801 IT-budsjettet som ble brukt på PC-ene i rådhuset.
</p
>
6803 <p
>Vi erfarte at skolene hadde mye datautstyr som stod ubrukt. Skolene
6804 manglet penger til Microsoft-lisenser. Selv med solide skolerabatter,
6805 kostet Microsoft-lisensene gjerne like mye som PC-ene i seg selv over
6806 en periode på
5-
6 år.
</p
>
6808 <p
>Viktigheten av språklig mangfold og pedagogiske programmer var også
6809 viktig for oss. Vi oversatte mange skoleaktuelle programmer til
6810 nynorsk, nordsamisk og bokmål. Dette lenge før andre tok denne
6811 oppgaven seriøst. Allerede etter ett år hadde vi etablert et helt
6812 arsenal av skoleaktuelle programmer på nynorsk, bokmål og
6813 nordsamisk. Vi spredde vår ide om språklig mangfold til de andre frie
6814 prosjekter internasjonalt. Resultatene ser vi i mange land. Det er de
6815 frie programmene som kommer på brukernes morsmål. Det er en av flere
6816 gode grunner til at fri programvare som LibreOffice, VLC, KDE og
6817 Firefox konkurrerer ut godseid programvare mange steder i verden.
</p
>
6819 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6821 <p
>Fordelene er at Skolelinux tilbyr over
100 skoleaktuelle programmer
6822 på de norske språkene, uten ett øre i lisenskostnader. Systemet gir
6823 enormt lave driftskostnader med diskløse arbeidsstasjoner og bærbare
6824 med roaming. Skolelinux krever også mindre av maskinvaren.
</p
>
6826 <p
>Man kan fint kjøre systemet med
512 MB RAM på en bærbar PC sammen
6827 med en nettvideo i nettleseren og en presentasjon med
6828 LibreOffice. Konkurrerende system krever fort
2 GB RAM for å få til
6829 noe tilsvarende uten at det går ufattelig tregt. Skal man gjøre noe
6830 nyttig, krever konkurrentene til Linux mye større harddisk. Skoler har
6831 rapportert at de fort har fått
50% flere nye maskiner om de velger
6832 Linux. Dette i tillegg til de årlige besparelsene ved å unngå
6833 lisensbetaling til godseid programvare.
</p
>
6835 <p
>De lave driftskostnadene gjør at delstater i Europa har titusener
6836 av datamaskiner med Skolelinux i skolen. F.eks. er det under ti
6837 personer som drifter
70.000 PC-systemer i skolene i Extremadura i
6838 Spania. Det er slett ikke uvanlig at norske kommuner har
1500-
2000
6839 datamaskiner med Skolelinux. Driften tar ett årsverk. Slår flere
6840 kommuner seg sammen, kan de få samme sentraliserte stordriftsfordeler
6841 som delstater i Tyskland og Spania. Delstater som kjører Skolelinux
6842 på alle skolene. Bare noen få personer sentraldrifter titusenvis av
6845 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6847 <p
>Den største ulempen for Skolelinux er motstand mot Linux fra
6848 IT-sjefer i det offentlige. Dette er ledere som holder innlegg som
6849 snytt ut av evangelist-håndboka til Microsoft. Dette gjøres i ett
6850 arbeidsmarked med stor vekst i etterspørselen etter Linux-fagfolk i
6851 privat sektor. Etterspørselen har økt mer enn noe annet tekniske yrke
6852 siste tiåret. Åtte av ti ledere vil ansette Linux-fagfolk i
2012,
6853 rapporterer jobbnettstedet Dice.com på oppdrag av Linux
6854 Foundation.
</p
>
6856 <p
>Det mangler
16.000 ingeniører og IKT-fagfolk i Norge rapporterte
6857 arbeids- og velferdsetaten NAV. Linux-fagfolk kan velge svært
6858 interessante jobber med alt fra apps på ledende mobilsystem laget med
6859 Linux, sky- tjenester eller web-applikasjoner. De raskest voksende
6860 teknologiselskapene i verden er ute etter Linux-fagfolk. Det være seg
6861 Amazon, Google, Facebook og IBM for å nevne noen. Linux er kritisk
6862 for å sikre veksten i markedet. Det sier seg selv at lønningene og
6863 jobbmulighetene er bedre enn for andre tekniske yrker.
</p
>
6865 <p
>Skal man lage apps for mobilen, smart-TV-en eller
6866 underholdningssystemet i bilen eller på flyet, er det Linux som
6867 gjelder. Med en slik konkurranse om Linux-kompetansen, kombinert med
6868 motstanden mot Linux hos mange IT-sjefer i offentlig sektor, så
6869 hindrer kommunene rekruttering av flere Linux- fagfolk. Skolene blir
6870 tvunget til å velge dyrere og mindre komplette IT-system. De har
6871 blitt hengende igjen slik IT var på begynnelsen av
2000- tallet. Dette
6872 fordi IT-ledere ikke har tilpasset seg markedet det siste tiåret.
</p
>
6874 <p
>Når det er sagt, er Skolelinux svært enkelt å lære seg også for de
6875 som ikke kan. Det viser alle lærerne som drifter systemet for
6876 hundrevis og tusenvis av systemer. Det meste er på plass rett ut av
6877 boksen. I tillegg er det solid med dokumentasjon med god hjelp på
6878 nettet. Det er mange kommuner som har ansatt en lærer som først lærte
6879 Skolelinux på sin skole, for så å drifte alle PC-ene i kommunen med
6880 Skolelinux. Det kan fort være snakk om
1000-
3000 datamaskiner på
10-
15
6881 skoler som sentraldriftes med en stilling. Står man ordentlig fast,
6882 kan man også kjøpe profesjonell hjelp fra selskap som støtter
6883 Skolelinux. Det er flere slike selskap i Norge og i utlandet.

6888 Debian-basert GNU/Linux-system. Jeg bruker også noen morsomme
6889 3D-spill. Idag kan jeg velge mellom over
30.000 Linux-programmer. Det
6890 finnes ikke tid i livet å undersøke alle valgmulighetene. Derfor er
6891 det bra med Skolelinux i skolen, da utvalget av programmer er
6892 begrenset til hva som er aktuelt i skolefagene.

6899 enkeltskoler eller hele kommuner. Pakken må inneholde tjenermaskiner,
6900 svært rimelige diskløse arbeidsstasjoner, nettbrett med Plasma Active,
6901 og bærbare med roaming. Alt er godt testet med Debian. I et slikt
6902 anbud er det mulig å legge til sentraliserte drifts- og
6903 støttetjenester.
</p

6905 <p
>Man bør også selge sky-tjenester som læreadministrative systemet

6908 selges til kommuner.

6946 <p
>Jeg kom i kontakt med prosjektet i
2009, da jeg ble ansatt i
6947 stiftelsen Åpne kontorprogram på norsk for å oversette og teste den
6948 norske utgaven av OpenOffice.org. Arbeidet har hele tiden vært
6949 koordinert sammen med Skolelinux, og mange av de samme menneskene er

6955 <p
>Skolelinux handler i likhet med utdanningssektoren om å dele
6956 kunnskap med andre, og det er dette som er hovedstyrken til
6957 prosjektet. Selv om Skolelinux hovedsaklig er involvert i utvikling
6958 av programvare, er det også et sted der man kan utfolde seg uavhengig
6959 av bakgrunn og ferdigheter.

6961 <p

6963 <p
>Liten utbredelse og manglende støtte fra leverandører som leverer
6964 pedagogisk programvare til skolebruk. Kunne kanskje hatt flere
6965 verktøy som letter administrasjonen ytterligere, slik at også mindre

1 med KDE4. Men
6973 hvis jeg skal dra fram noen flere eksempler så er nok Mozilla Firefox
6974 og Thunderbird to av de jeg bruker mest. I tillegg er jeg en flittig
6975 bruker av OpenSSH, Irssi, Midnight Commander, Git, Subversion,
6976 Translation Toolkit og Super Maryo Chronicles (litt gøy skal man ha,

6982 <p
>Vi må få leverandører av pedagogisk programvare med på laget, men
6983 også utvikle vår egen tilpasset det norske markedet. Det er også
6984 mulig å involvere utdanningssektoren direkte i arbeidet, for eksempel
6985 gjennom studentprosjekter der elevene selv er med å utforme
6986 programvare direkte eller indirekte gjennom aktive bidrag. Dette gjør
6987 ikke bare samarbeidet tettere, men fokuset på standarder og friheten
6988 til å velge sin egen løsning vil kanskje stimulere interessen for
6989 framtidig deltakelse i bransjen. Vi som driver med fri og åpen
6990 programvare ønsker oss ikke rene konsumenter, men tenkende og
6991 selvstendige individer som kan være med å skape sin egen fremtid.

>New in the Squeeze version of
7001 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> is the
7002 ability for clients to automatically configure their proxy settings
7003 based on their environment. We want all systems on the client to use
7004 the WPAD based proxy definition fetched from
<tt
>http://wpad/wpad.dat
</tt
>, to
7005 allow sites to control the proxy setting from a central place and make
7006 sure clients do not have hard coded proxy settings. The schools can
7007 change the global proxy setting by editing
7008 <tt
>tjener:/etc/debian-edu/www/wpad.dat
</tt
> and the change propagate
7009 to all Debian Edu clients in the network.
</p
>
7011 <p
>The problem is that some systems do not understand the WPAD system.
7012 In other words, how do one get from a WPAD file like this (this is a
7013 simple one, they can run arbitrary code):
</p

7015 <blockquote

7018 if (!isResolvable(host) ||
7019 isPlainHostName(host) ||
7020 dnsDomainIs(host,
".intern
"))
7021 return
"DIRECT
";
7023 return
"PROXY webcache:
3128; DIRECT
";
7025 </pre

7027 <p
>to a proxy setting in the process environment looking like this:
</p
>
7029 <blockquote
><pre
>
7030 http_proxy=http://webcache:
3128/
7031 ftp_proxy=http://webcache:
3128/
7032 </pre
></blockquote
>
7034 <p
>To do this conversion I developed a perl script that will execute
7035 the javascript fragment in the WPAD file and return the proxy that
7037 <tt
><a href=
"http://www.debian.org/
">http://www.debian.org/
</a
></tt
>,
7038 and insert this extracted proxy URL in
<tt
>/etc/environment
</tt
> and
7039 <tt
>/etc/apt/apt.conf
</tt
>. The perl script wpad-extract work just
7040 fine in Squeeze, but in Wheezy the library it need to run the
7041 javascript code is
<a href=
"http://bugs.debian.org/
631045">no longer
7042 able to build
</a
> because the C library it depended on is now a C++
7043 library. I hope someone find a solution to that problem before Wheezy
7044 is frozen. An alternative would be for us to rewrite wpad-extract to
7045 use some other javascript library currently working in Wheezy, but no
7046 known alternative is known at the moment.
</p
>
7048 <p
>This automatic proxy system allow the roaming workstation (aka
7049 laptop) setup in Debian Edu/Squeeze to use the proxy when the laptop
7050 is connected to the backbone network in a Debian Edu setup, and to
7051 automatically use any proxy present and announced using the WPAD
7052 feature when it is connected to other networks. And if no proxy is
7053 announced, direct connections will be used instead.
</p
>
7055 <p
>Silently using a proxy announced on the network might be a privacy
7056 or security problem. But those controlling DHCP and DNS on a network
7057 could just as easily set up a transparent proxy, and force all HTTP
7058 and FTP connections to use a proxy anyway, so I consider that
7059 distinction to be academic. If you are afraid of using the wrong
7060 proxy, you should avoid connecting to the network in question in the
7061 first place. In Debian Edu, the proxy setup is updated using dhcp and
7062 ifupdown hooks, to make sure the configuration is updated every time
7063 the network setup changes.
</p
>
7065 <p
>The WPAD system is documented in a

7117 var noen annen løsning. «Vandrende arbeidsstasjon» mener jeg ikke
7118 fantes da. Dessuten ville jeg ha siste versjon, da den KDE-versjonen

>Since the Lenny version of
7160 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>, a
7161 feature to save power have been included. It is as simple as it is
7162 practical: Shut down unused clients at night, and turn them on again
7163 in the morning. This is done using the
7164 <a href=
"http://packages.qa.debian.org/s/shutdown-at-night.html
">shutdown-at-night
</a
> Debian package.
</p
>
7166 <p
>To enable this feature on a client, the machine need to be added to
7167 the netgroup shutdown-at-night-hosts. For Debian Edu, this is done in
7168 LDAP, and once this is in place, the machine in question will check
7169 every hour from
16:
00 until
06:
00 to see if the machine is unused, and
7170 shut it down if it is. If the hardware in question is supported by
7172 <a href=
"http://packages.qa.debian.org/n/nvram-wakeup.html
">nvram-wakeup
</a
>
7173 package, the BIOS is told to turn the machine back on around
07:
00 +-
7174 10 minutes. If this isn
't working, one can configure wake-on-lan to
7175 try to turn on the client. The wake-on-lan option is only documented
7176 and not enabled by default in Debian Edu.
</p
>
7178 <p
>It is important to not turn all machines on at once, as this can
7179 blow a fuse if several computers are connected to the same fuse like
7180 the common setup for a classroom. The nvram-wakeup method only work
7181 for machines with a functioning hardware/BIOS clock. I
've seen old
7182 machines where the BIOS battery were dead and the hardware clock were
7183 starting from
0 (or was it
1990?) every boot. If you have one of
7184 those, you have to turn on the computer manually.
</p
>
7186 <p
>The shutdown-at-night package is completely self contained, and can
7187 also be used outside the Debian Edu environment. For those without a
7188 central LDAP server with netgroups, one can instead touch the file
7189 <tt
>/etc/shutdown-at-night/shutdown-at-night
</tt
> to enable it.
7190 Perhaps you too can use it to save some power?

>I am happy to announce that finally we managed today to wrap up and
7200 publish the third beta version of
7201 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> based
7202 on Squeeze. If you want to test a LDAP backed Kerberos server with
7203 out of the box PXE configuration for running diskless machines and
7204 installing new machines, check it out. If you need a software
7205 solution for your school, check it out too. The full announcement is
7206 <a href=
"http://lists.debian.org/debian-edu-announce/
2012/
02/msg00000.html
">available
</a
>
7207 on the project announcement list.
</p
>
7209 <p
>I am very happy to report these changes and improvements since
7210 beta2 (there are more, see announcement for full list):
</p
>
7214 <li
>It is now possible to change the pre-configured IP subnet from
7215 10.0.0.0/
8 to something else by using the subnet-change tool after
7216 the installation.
</li
>
7218 <li
>Too full partitions are now automatically extended on the Main
7219 Server, based on the rules specified in /etc/fsautoresizetab.
</li
>
7221 <li
>The CUPS queues are now automatically flushed every night, and all
7222 disabled queues are restarted every hour. This should cut down on
7223 the amount of manual administration needed for printers.
</li
>
7225 <li
>The set of initial users have been changed. Now a personal user
7226 for the local system administrator is created during installation
7227 instead of the previously created localadmin and super-admin users,
7228 and this user is granted administrative privileges using group
7229 membership. This reduces the number of passwords one need to keep
7230 up to date on the system.
</li
>
7234 <p
>The new main server seem to work so well that I am testing it as my
7235 private DNS/LDAP/Kerberos/PXE/LTSP server at home. I will use it look
7236 for issues we could fix to polish Debian Edu even further before the
7237 final Squeeze release is published.
</p
>
7239 <p
>Next weekend the project organise a
7240 <a href=
"http://lists.debian.org/debian-edu-announce/
2012/
01/msg00001.html
">developer
7241 gathering
</a
> in Oslo. We will continue the work on the Squeeze
7242 version, and start initial planning for the Wheezy version. Perhaps I
7243 will see you there?

>With some computer hardware, one need non-free firmware blobs.
7253 This is the sad fact of todays computers. In the next version of
7254 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> based
7255 on Squeeze, we provide several scripts and modifications to make
7256 firmware blobs easier to handle. The common use case I run into is a
7257 laptop with a wireless network card requiring non-free firmware to
7258 work, but there are other use cases as well.
</p
>
7260 <p
>First and foremost, Debian Edu provide ISO images for DVD and CD
7261 with all firmware packages in the Debian sections main and non-free
7262 included, to ensure debian-installer find and can install all of them
7263 during installation. This take care firmware for network devices used
7264 by the installer when installing from from local media. But for
7265 example multimedia devices are not activated in the installer and are
7266 not taken care of by this.
</p
>
7268 <p
>For non-network devices, we provide the script
7269 <tt
>/usr/share/debian-edu-config/tools/auto-addfirmware
</tt
> which
7270 search through the
<tt
>dmesg
</tt
> output for drivers requesting extra
7271 firmware. The firmware file name is looked up in the Contents-ARCH.gz
7272 file available in the package repository, and the packages providing
7273 the requested firmware file(s) is installed. I have proposed to do
7274 something similar in debian-installer (BTS report
7275 <a href=
"http://bugs.debian.org/
655507">#
655507</a
>), to allow PXE
7276 installs of Debian to handle firmware installation better. Run the
7277 script as root from the command line to fetch and install the needed
7278 firmware packages.
</p
>
7280 <p
>Debian Edu provide PXE installation of Debian out of the box, and
7281 because some machines need firmware to get their network cards
7282 working, the installation initrd some times need extra firmware
7283 included to be able to install at all. To fill the PXE installation
7284 initrd with extra firmware, the
7285 <tt
>/usr/share/debian-edu-config/tools/pxe-addfirmware
</tt
> script is
7286 provided. Again, just run it as root on the command line to fill the
7287 PXE initrd with firmware packages.
</p
>
7289 <p
>Last, some LTSP clients might also need firmware to get their
7290 network cards working. For this,
7291 <tt
>/usr/share/debian-edu-config/tools/ltsp-addfirmware
</tt
> is
7292 provided to update the LTSP initrd with firmware blobs. It is used
7293 the same way as the other firmware related tools.
</p
>
7295 <p
>At the moment, we do not run any of these during installation. We
7296 do not know if this is acceptable for the local administrator to use
7297 non-free software, and it is their choice.
</p

7299 <p

>The next version of
<a href=

">Debian Edu
7356 / Skolelinux
</a
> will include a new tool
7357 <tt
>sitesummary2ldapdhcp
</tt
>, which can be used to quickly set up all
7358 the computers in a school without much manual labour. Here is a short
7359 summary on how to use it to set up a new school.
</p
>
7361 <p
>First, install a combined Main Server and Thin Client Server as the
7362 central server in the network. Next, PXE boot all the client machines
7363 as thin clients and wait
5 minutes after the last client booted to
7364 allow the clients to report their existence to the central server. When
7365 this is done, log on to the central server and run
7366 <tt
>sitesummary2ldapdhcp -a
</tt
> in the
<tt
>konsole
</tt
> to use the
7367 collected information to generate system objects in LDAP. The output
7368 will look similar to this:
</p
>
7370 <p
><blockquote

></blockquote
></p
>
7382 <p
>After providing the LDAP administrative password (the same as the
7383 root password set during installation), the LDAP database will be
7384 populated with system objects for each PXE booted machine with
7385 automatically generated names. The final step to set up the school is
7386 then to log into
<a href=
"https://oss.gonicus.de/labs/gosa/
">GOsa
</a
>,
7387 the web based user, group and system administration system to change
7388 system names, add systems to the correct host groups and finally
7389 enable DHCP and DNS for the systems. All clients that should be used
7390 as diskless workstations should be added to the workstation-hosts
7391 group. After this is done, all computers can be booted again via PXE
7392 and get their assigned names and group based configuration
7393 automatically.

>I serien med intervjuer av folk i
7410 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet, har jeg nå
7411 lyktes med å få tak i en skolemann som ikke er aktiv med utviklingen,
7412 men likevel har vært med nesten siden starten av prosjektet. Jeg
7413 ønsker derfor velkommen til Paul Reidar Løsnesløkken, en mann med
7414 mange års erfaring i bruk av Skolelinux.
</p

7416 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
7418 <p
>Jeg driftet tidligere IKT løsningen for skolene i
7419 <a href=
"http://www.nord-odal.kommune.no/
">Nord-Odal
</a
>. I dag er jeg
7420 IKT-konsulent for hele kommunen og samarbeider med
7421 <a href=
"http://www.hedmarken-ikt.no/
">Hedmark-IKT
</a
> for best mulig
7422 tjenester til kommunen. Jeg har bakgrunn som elektronikkreparatør og
7423 grunnskolelærer og har tatt en del fag innen IKT, i hovedsak
7424 driftsfag. IKT i Nord-Odal kommune blir i dag driftet av Hedmark IKT
7425 som er et samarbeid mellom Løten, Stange, Grue, Hamar, Kongsvinger og
7426 Nord-Odal. Jeg er fortsatt
"IKT-personen
" på skolene i kommunen og
7427 følger opp og gjør enkelte mindre endringer der.
</p
>
7429 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
7431 <p
>Kommunen satset på Skolelinux i
2004. Jeg var ikke med i
7432 beslutningsprosessen den gang, men ble likevel med fra starten når
7433 dette ble levert.
</p
>
7435 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7437 <p
>Fordelene med Skolelinux er rask oppstart, sentral drift av
7438 klientene, klienter som jobber raskt og effektivt, bedre
7439 funksjonalitet på eldre utstyr og en ganske god programpakke med fri
7440 programvare som følger med. Løsningen med halvtykke klienter gjør at
7441 prosessering skjer lokalt med alltid ferske maskiner.
</p
>
7443 <p
>Skolelinux kan fungere godt på gammelt utstyr, men det er klart at
7444 utstyr også blir for gammelt selv for Skolelinux. I forbindelese med
7445 at vi nylig fikk nye servere og ny installasjon kastet jeg ut ca
60
7446 klienter som fortsatt var i drift etter at de var kjøpt godt brukt i
7447 2004. Noe var rundt
15 år gammelt, men var fortsatt i bruk. Noen
7448 klaget på at det nå gikk veldig tregt på en del pedagogiske nettsider
7449 med flash o.l. Det er fullt forståelig.
</p
>
7451 <p
>Jeg fikk nylig et spørsmål fra ungdomsskolens rektor om jeg kunne
7452 legge inn
<a href=
"http://freemind.sourceforge.net/
">FreeMind
</a
>, et
7453 tankekartprogram , på skolens elev-Windowsmaskiner. Lærerne hadde
7454 vært på kurs og ville ta dette i bruk. Skolen har ca halvparten av
7455 elevmaskinene på bærbare Windowsmaskiner. Da kunne jeg fortelle at
7456 dette programmet allerede lå inne på den nye Skolelinuxløsningen
7457 som nettopp var satt i drift, klart til bruk.
</p
>
7459 <p
>Vi har de bærbare maskinene på ungdomsskolen i domene med
7460 Skolelinux. Dette fungerer også meget bra nå. Elevene får opp en
7461 midlertidig windowsprofil når de logger på. Denne profilen slettes
7462 etter at de logger av, noe som medfører rene profiler hver gang de
7463 starter opp en maskin. De må lagre i sin Skolelinprofil, noe som
7464 medfører at de får tak i sine filer uavhengig av om de starter en
7465 Windowsmaskin eller en Skolelinuxklient. Det er mye mindre trafikk i
7466 det trådløse nettet etter at ikke hele profiler blir lastet opp til de
7467 enkelte Windowsmaskinene og tilbake når man avslutter. Jeg vet ikke om
7468 dette er standardoppsett i Skolelinux, men slik er vårt oppsett
7471 <p
>Vi har i flere år satt opp vår løsning slik at skriverkøer slettes
7472 og skrivere startes hver natt. Hyggelig å høre at dette nå skal bli
7473 en standard i Skolelinuxløsningen. Dette har vært en god hjelp for
7476 <p
>Elevene er lite opptatt av om de jobber på en Skolelinux eller en
7477 Windowsmaskin bare de har de programmene de trenger og at det virker
7478 når det skal brukes. Vi kjører mest mulig de samme programmene på
7479 Windows som i Skolelinux, som f.eks Audacity og LibreOffice.
</p
>
7481 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7483 <p
>Lærere bruker hos oss Windows. Dette fordi de da selv har mer
7484 kontroll over sin maskin, kan bruke den overalt, og kan legge inn
7485 programmer selv når de trenger noe i forhold til kurs o.l de er
7486 på. Jeg tror lærernes selvstendighet her gjør dem tryggere på IKT-bruk
7487 generelt. Det at de av og til får opp advarsler og lignende gjør også
7488 at de må tenke igjennom og spørre om ting rundt datasikkerhet.
</p
>
7490 <p
>Det er en del programmer vi bruker som ikke finnes for Linux. Mest
7491 brukt er nok Photostory3 som brukes i mange sammenhenger, særlig på
7492 ungdomsskolen, bl.a. til å lage herbarier (plantesamling) . Dette
7493 finnes gratis for Windows, men er ikke fri programvare. Vi er opptatt
7494 av at programmer elevene bruker på skolen også kan brukes gratis
7495 hjemme. Det er også en del programmer som brukes til spesielle elever
7496 som bare går i Windows. Det er viktig med fokus på funksjoner og ikke
7497 på hvilket OS man bruker.
</p
>
7499 <p
>For oss er det kombinasjonen mellom Skolelinux og Windows som gir
7500 oss en god og hel løsning. Skolelinux er best der de er gode.
</p
>
7502 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
7504 <p
>Selv er det LibreOffice jeg bruker til daglig. Jeg bruker selv en
7505 Windowsmaskin. Jeg har benyttet en del fri programvare i forbindelse
7506 med sjekking av trafikk i nettverk, slik som Wireshark, men dette er
7507 jo ikke aktuelt for skolene. Jeg er generelt glad i programmer som
7508 fungerer på både Linux og Windows og gjerne MAC.
</p
>
7510 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
7511 skoler til å ta i bruk fri programvare?
</strong
></p
>
7513 <p
>Det er viktig at det benyttes programmer som elevene også kan ta i
7514 bruk hjemme. Det skal da være enkelt, lovlig og gratis for
7515 elevene. Da er jeg ikke lenger veldig opptatt av om det kalles
"fri
7516 programvare
". For skolene tror jeg
"gratis
" og
"funksjonelt
" er bedre
7517 begreper enn
"fri
" i forhold til programmer. De fleste skiller nok
7518 ikke mellom
"fri
" og
"gratis
". Det er nå svært mange elever som
7519 benytter OpenOffice eller LibreOffice som sin primære kontorpakke

>During christmas, I have been working getting the next version of
7576 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> ready
7577 for release. The initial problem I looked at was particularly
7578 interesting.
</p
>
7580 <P
>The installer would hang at the end when it was doing it
7581 post-installation configuration, and whatevery I did to try to find
7582 the cause and fix it always worked while I tested it, but never when I
7583 integrated it into the installer and ran the installation from
7584 scratch. I would try to restart processes, close file descriptors,
7585 remove or create files, and the installer would always unblock and
7586 wrap up its tasks.
</p
>
7588 <p
>Eventually the cause was found. The kernel was simply running out
7589 of entropy, causing the Kerberos setup to hang waiting for more.
7590 Pressing keys was adding entropy to the kernel, and thus all my tries
7591 to fix the problem worked not because what I was typing to fix it, but
7592 because I was typing.
</P
>
7594 <p
>The fix I implemented was to add a background process looking at
7595 the level of entropy in the kernel (by checking
7596 /proc/sys/kernel/random/entropy_avail), and if it was too small, the
7597 installer will flush the kernel file buffers and do
'find /
' to
7598 generate some disk IO. Disk IO generate entropy in the kernel, and is
7599 one of the few things that can be initated from within the system to
7600 generate entropy.

>Etter en lang pause er det klart for neste mann ut i min serie med
7617 <a href=

">Skolelinux

7619 Denne gangen har jeg besøk av et avtroppende styremedlem i
7620 <a href=

7621 som har vært aktiv i Linux-miljøet i Bergen siden
90-tallet.

</strong

>
7625 <p
>Jeg heter Peter Hansteen, og jobber til daglig som seniorkonsulent
7626 i EDB ErgoGroup i Bergen. I praksis betyr det systemadministrasjon på
7627 Unix (primært Solaris, men en viss komponent av Linux). Men Solaris
7628 er for meg et relativt nytt bekjentskap, hovedplattformen min har
7629 generelt vært OpenBSD og til dels FreeBSD.
</p

7631 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
7633 <p
>Jeg husker ikke helt alle detaljene mer ;) - men jeg tror det var
7634 gjennom news-gruppen no.it.os.unix.linux.diverse, efn-listen og
7635 etterhvert også BLUG-miljøet her i Bergen. Vi hadde et par
7636 Skolelinux-sentrerte BLUG-møter for noen år siden, og det har vært et
7637 par Skolelinux-utviklersamlinger her.
</p
>
7639 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7641 <p
>Jeg bruker dessverre ikke Skolelinux daglig. Men slik jeg kjenner
7642 prosjektet har det vært i stand til å ta opp i seg det beste av fri
7643 programvare i mange kategorier, så fra et sysadmin-perspektiv ser det
7644 ut som en svært behagelig sak. For brukerne er det vel både en fordel
7645 og en ulempe at det ikke er Windows. Men vi håper at fordelene med et
7646 fritt system etterhvert vil bli åpenbare for både elever, lærekrefter
7647 og foreldre.
</p
>
7649 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7651 <p
>Vel, ulempen er vel først og fremst at andre aktører med mer
7652 kapitalmuskel har klart å etablere seg som det både lærere og foreldre
7653 føler seg trygge på, selv om det etter mitt hode ikke er noen grunn
7654 til å være spesielt trygg på de kommersielle alternativene.
</p
>
7656 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
7658 <p
>Når jeg får bestemme helt selv, bruker jeg kun fri programvare. Da
7659 helst med vekt på ting som kjører greit på OpenBSD. Hjemme er det
7660 OpenBSD, Ubuntu eller FreeBSD vi bruker. På skrivebordet er det en
7661 avveining mellom Gnome, KDE eller hva-det-nå-heter som er
7662 standardvalget i Ubuntu, ellers er det de kjente tingene som
7663 LibreOffice, Emacs, mplayer. På server er det selvfølgelig Apache,
7664 for overvåking både OpenNMS og Nagios (det bare ble sånn, og
7665 forskjellige siter). Jeg skriver til tider om slikt jeg holder på med
7667 <a href=
"http://bsdly.blogspot.com
">http://bsdly.blogspot.com
</a
>.
</p
>
7669 <p
>Men vi må nevne at selv vi har en Microsoft-ting som vi slår på når
7670 vi av en eller annen grunn må. Det betyr igjen vanligvis når en
7671 mobiltelefon eller en annen lukket elektronisk dings krever kontakt
7672 via en slik for å få oppdateringene sine.
</p
>
7674 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
7675 skoler til å ta i bruk fri programvare?
</strong
></p
>
7677 <p
>Hadde vi hatt det rette svaret på det spørsmålet, så hadde vi
7678 gjerne hatt Skolelinux som førstevalg på alle skoler ;)
</p
>
7680 <p
>Men jeg tror vi må legge vekt på flere forskjellige ting. En helt
7681 sentral sak er å fokusere på fri programvare og åpne standarder som de
7682 demokratiske verdiene de faktisk er. Det har kanskje kommet litt for
7683 mye i bakgrunnen i forhold til strevet etter å lage det mest mulig
7684 'brukervennlige
' systemet. Det er en tung vei å gå, så det er
7685 forståelig at freenix-aktivister heller velger å skrive kode og annet
7686 som er mer lystbetont. Mer praktisk tror jeg vi må gjøre i alle fall
7687 to ting: For det første sørge for å fortsette med å levere det best
7688 mulige frie produktet, slik at det er lett å både komme i gang og
7689 holde systemene i daglig drift, og for det andre
2) spore opp mulige
7690 aktivister der de finnes, via lokale brukergrupper, sosiale medier
7691 eller annet og sørge for at de fortsetter å være aktive. Mer og
7692 mindre uformelle treff kan være nyttig i tillegg til de mer
7693 organiserte møtene med foredrag, konferanser og utviklersamlinger.

7718 <p
>Jobbet i IBM fra
2000, og da spesielt med Linux. Dette var da et av
7719 de mest tydelige linux prosjektene i Norge, og her ønsket jeg å
7720 bidra. Var aktivt med i prosjektet i
4-
5 år.
</p
>
7722 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7724 <p
>Fordelene slik jeg ser det er den sentraliserte driftmodellen, og
7725 alle de vel gjennomtenkte løsningene som er inkludert i denne
7726 løsningen. Samtidig er det basert på en stabil, og godt kjent
7727 plattform. Dette vil si at man har en løsning som skal være mye
7728 tilgjengelig, og hvor det er relativt enkelt å få tak i personer som
7729 kan mye om den grunnleggende plattformen.
</p
>
7731 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7733 <p
>De største utfordringene med en løsningen er at den er intensiv på f.eks
7734 nettverk. I seg selv ikke et problem for en enkelt skole, men skal løsningen
7735 kjøres i større skala, med sentraliserte servere, så gir dette noen
7736 utfordringer.
</p
>
7738 <p
>Utifra hva jeg har sett på større installasjoner så er det ikke så
7739 enkelt å skjønne, hva som bør gjøres for at den skal skaleres opp, og
7740 da ta godt vare på alle sider av dette, ikke bare mer server å fordele
7741 last/trykk, men hvordan også beholde robustheten og fleksibiliteten i
7742 løsningen.
</p
>
7744 <p
>En annen utfordring er at stadig flere produkter som skal brukes i
7745 skoleløsningen ikke er laget til å kunne brukes i en
7746 skolelinuxløsning. Det blir derfor fort mye skreddersøm i de
7747 forskjellige installasjonene, for å få diverse pedagogiske programmer,
7748 webløsninger, smartboards, m.m. til å fungere. Man er også en for
7749 liten kundebase til at leverandørene ønsker å gjøre noe med
7750 utfordringen. Problemet overlates til oss.
</p
>
7752 <p
>Det er også en kontinuerlig utfordring rundt problemet med å holde
7753 programvare på stabile versjoner, kontra å få ny funksjonalitet. Dette
7754 er jo en konflikt mellom oss som ønsker å drifte en stabil, og
7755 kostnadseffektiv løsning, mot sluttbrukerne som ønsker seg funksjoner
7756 det er vant med fra andre løsninger, eller som de må ha for at et
7757 eller annet nytt produkt skal fungere i løsningen. Dette er en
7758 utfordring også for andre plattformer.
</p
>
7760 <p
>En siste utfordring som ikke har noe med løsningen å gjøre, men med
7761 det omkringliggende miljøet denne skal kjøre i, er at de enhetene som
7762 skal drifte dataløsninger for kommuner og fylkeskommuner begynner å
7763 profesjonaliseres, og er da avhengig av å ha standard løsninger for å
7764 drifte store brukermasser. MS er selvsagt klar over dette, og har jo
7765 nå flere områder de begynner å bli veldig dominerende på. Den største,
7766 og mest problematiske er katalogtjenesten. Man får snart ikke tak i
7767 større løsninger som ikke krever en AD. Når man da har store enheter
7768 som drifter både kommunalt ansatte og skoler, så vil det være et
7769 stordriftargument å standardisere på en katalog tjeneste, og da har
7770 man ikke noe valg. Her er alle slike driftsenheter for små til å få
7771 gjort om på dette. Her burde konkurransemyndighetene kommet på
7772 banen. Men konkurransetilsynet i USA griper sjeldent (og ikke før det
7773 har gått veldig lang tid) inn i monopolsituasjoner så lenge
7774 monopolisten er et amerikansk firma, så da har vel ikke andre
7775 myndigheter så mye de skulle ha sagt....

15-

7782 programvare. Av enkelt programmer kan sikkert masse nevnes. Hvis vi
7783 skal begrense oss til daglig, så må jeg si: OpenOffice, Firefox,
7784 Kontact, Kopete, Amarok,

</p

7793 <p
>Argumentene som ofte har vært brukt om at ting koster mindre holder
7794 ikke mål når man ser på hva som faktisk koster penger. Det er de
7795 ansatte som er en kostnadsdriver. Det vil si at hvis man har et system
7796 som den ansatte kan, så vil en kostnad på dette systemet kunne
7797 forsvares ganske mye ved at den ansatte gjør dette raskere og
7798 effektivt. Også uten å måtte eventuelt leie inn folk.

7800 <p
>Jeg syns det er viktigere å fokusere på prinsippet med å velge fri
7801 programvare, men det er også et felt hvor man fort møter lite
7802 forståelse blant de ansatte i skolen.
</p
>
7804 <p
>Her må nok strategien fortsette å være at de sentrale myndighetene
7805 må sende tydelige signaler for hva de ønsker at offentlige enheter
7806 skal gjøre. Det var mye positivt på gang ang. dette for et par år
7807 siden. Både med eNorge og eKommune planene, men dette syns jeg har
7808 stoppet opp. En del av dette kan jo kanskje være usikkerheten som
7809 etter hvert har blitt, når man har sett kompleksiteten i de
7810 prosjektene som har blitt igangsatt. Det har også blitt noe usikkerhet
7811 i markedet ref. Sun, Oracle, Novell, Microsoft m.m. Samtidig har jo
7812 også de proprietære programleverandørene sørget for å endre sine
7813 lisenser slik at man uansett ikke slipper unna kostnaden til deres
7814 produkter, selv om man skulle velge alternativer. Da er det økonomiske
7815 argumentet, som jeg nevnte tidligere, spilt ganske godt ut over
7816 sidelinjen.

7840 hadde vel hørt om prosjektet i media før en gjeng i Trondheim startet
7841 opp SPIST, Skolelinux-prosjektet i Sør-Trøndelag, hvor vi hjalp noen
7842 skoler i nærområdet med å installere Skolelinux og finne brukt
7843 IT-utstyr til disse. Det var moro å gjøre noe praktisk for å spre
7844 Skolelinux, og å se hvor fort gjort det var å sette opp utrangerte
7845 klientmaskiner og få disse opp som tynnklienter på helt nye datasaler
7846 på skolene, kun med kostnaden til servere.

7850 <p
>Det er et system spesielt skreddersydd for drift av et stort antall

7852 er enkelt og billig å installere og drifte, og det trenger ikke ny
7853 maskinvare for god ytelse.

7857 <p
>Hardwarestøtten kunne vært bedre og i enda større grad
7858 installerbart rett ut av boksen. Distribusjonen har til tider hatt
7859 litt gammel programvare pga. at den følger Debian sine utgivelser.
7860 Kanskje man skulle vurdert en versjon basert på Ubuntu eller andre
7861 distribusjoner i tillegg?

7868 Telefonen min er en Android, og der bruker jeg programmene K-

7869 OI Shopping list, Shuffle, ZXing, OI Notepad og ADW Desktop. På jobb
7870 bruker jeg JBoss, Eclipse, uCLinux for Blackfin, RCF-CPP, Qt, Maven,

>En bør fokusere på totalkostnader inkludert driftsbehov,
7877 fleksibilitet, åpenhet og ikke låsing til en leverandør framfor sparte
7878 lisenskostnader, samt programvarens kvalitet og fortrinn, og at den
7879 fritt kan brukes på et ubegrenset antall PC-er, også hjemme hos
7880 elevene. En bør også forbedre den fri programvaren ved testing,
7881 bugrapportering og kodebidrag om man kan, og ikke anbefale programvare
7882 uten at man har forsikret seg at den har tilstrekkelig kvalitet,
7883 ellers kan man lett oppnå det motsatte. Tror en bør selge inn
7884 konseptet til fylkes-/statsnivå, kanskje med bidrag til
7885 utviklingsarbeid fra disse som alle landets skoler kan få glede

>Mine bloggposter om Linux i skolene i Norge førte til at inspektør
7896 og ildsjel på Harestad skole tok kontakt og fortalte at de bruker
7897 Linux på sin skole, og lurte på om de kunne bidra til å gjøre
7898 fordelene kjent. Riktig nok bruker de ikke
7899 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
> på denne skolen,
7900 men jeg synes dette er en god anledning til å gjøre flere fasetter
7901 rundt Linux-økosystemet kjent, og tok et lite intervju.
</p

7903 <p
><strong

7905 <p
>Mitt navn er Odin Hetland Nøsen og er en
70-modell. Jeg er bosatt i
7906 Stavanger og jobber nå på
9. året som undervisninginspektør på
7907 Harestad skole i Randaberg kommune (nabokommune til Stavanger).
</p

7909 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
7911 <p
>I
2002 begynte daværende IKT-ansvarlige og jeg et arbeid på skolen
7912 med å gå over fra Win98 til... noe annet. Vi testet en rekke
7913 forskjellige løsninger, deriblant Skolelinux, men endte opp med
7914 RedHat. Skolelinux var den gang ikke modent for det vi ville ha. Jeg
7915 har siden fulgt jevnlig med på hva skolelinux holder på med, men har
7916 hele tiden vært bedre fornøyd med vår egen
"standardiserte
" løsning på
7917 RedHat/CentOS og Fedora. Vi snuser for tiden på Ubuntu som løsning på
7918 klientsiden.
</p
>
7920 <p
>I dag har vi på skolen vår en større linux-løsning med
400 klienter
7921 som kjører en blanding av LTSP (tynnklient) og DRBL (tykk klient uten
7922 harddisk) med en masse tjenere på serverrommet. Vi drifter hele
7923 sulamitten selv med webtjener, eposttjener, webmail, filtjenere,
7924 virtuelle tjenere osv. Og IT-ansvarlig har en
80% stilling som
7925 IT-ansvarlig - og så er han KoH-lærer i de resterende
20% :-)

7927 <p
>Du kan få en ide om hva vi holder på med om du går inn på
7928 <a href=
"http://www.gnuskole.no/
">http://www.gnuskole.no/
</a
>.
</p
>
7930 <p
>For å ta brodden av frykten for at ildsjeler gjør skolen sårbar om
7931 ildsjelene falle fra, har jeg forsikret kommunen og skolesjefen i
7932 Randaberg om at det finnes godt kommersielle tjenester vi kan benytte
7933 oss av - om det skulle bli nødvendig. Vi er tre stykker i kommunen som
7934 nå har
<strong
>god
</strong
> linux-kompetanse ift. å drifte et større
7935 system. IT-avdelingen i kommunen vil ikke ta på oss med ildtang -
7936 selv om vi nok har større IT-kompetanse mot linux enn det de selv har
7937 mot windows (de kjøper en
<strong
>masse
</strong
> konsulenttjenester
7938 fra ErgoGroup).
</p
>
7940 <p
>I kvantitet er Harestad og Grødem skole tilsammen et større
7941 IT-system enn resten av Randaberg kommune + Kvitsøy og Rennesøy, som
7942 kommunen også har driftsansvar for. Vi har som sagt rundt
800
7943 maskiner, mens kommunen med sitt driftsansvar har ansvar for rundt
500
7944 maskiner. Det er selvfølgelig litt forskjell i hvor kritiske
7945 tjenestene våre er, men det gir allikevel et litt rart bilde når
7946 IT-avdelingen overhode ikke er interessert i å snakke med oss om
7947 hvordan vi gjør ting :-)
</p
>
7949 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7951 <p
>Fra linux-perspektivet (ikke bare Skolelinux) er det en fordel av
7952 systemet er basert på fri programvare - og dermed fritt i ordets mange
7953 betydninger. Det er alt vi trenger: stabilt, relativt enkelt å drifte
7954 (tross alt - et større windowssystem er ikke enkelt å holde live det
7955 heller), rimelig i innkjøp og drift, og sist, men ikke minst, det er
7956 moderne for sluttbruker! Linux, i sine mange varianter,
7957 <strong
>ser
</strong
> nytt ut, fordi det hele tiden blir
7958 oppdatert. Derfor lever systemet opp til hvordan elever forventer at
7959 et moderne GUI skal være (i motsetning til WinXP :-).
</p
>
7961 <p
>Vi var veldig pragmatiske da vi begynte med linux i skolen. Det var
7962 billig, det fungerte og kunne bruke alle de gamle windows-maskinene
7963 som
"nye
" tynne klienter. I dag er vi mer bevisste fri
7964 programvare-tilhengere. Vi har oppdaget hva det er - og vi liker
7967 <p
>En av de
<strong
>store
</strong
> fordelene med fri programvare er at
7968 vi kan installere tjenester vi ønsker å tilby brukerne våre - uten å
7969 måtte tenke på om vi har råd til lisensene (fordi det er ingen). Alt
7970 vi setter i produksjon er ut i fra brukernes behov og vår kapasitet
7971 til å drifte dem. Vi skreddersyr tjenestene etter behovet og dermed
7972 trenger vi ikke ende opp med å kjøpe en pakke der vi egentlig bare var
7973 interessert i en liten del av den.
</p
>
7975 <p
>Bruk av linux frigjør ikke økonomiske midler, fordi midlene til IKT
7976 i skole er for få i utgangspunktet - men vi får så
7977 <strong
>mye
</strong
> mer igjen for dem når vi bruker en linux-løsning
7978 fremfor en windows-løsning. I praksis ser vi at vi måtte ut med det
7979 dobbelte på budsjettet vårt om vi skulle hatt en tilsvarende
7980 windows-løsning, som det vi i dag drifter med linux.
</p
>
7982 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7984 <p
>Ikke all pedagogisk programvare er tilgjengelig. Det er en del
7985 programvare i skolen som er laget med utviklerverktøy som bare virker
7986 i windows, f.eks. Drillpro, LingDys/LingWrite. Det er også
7987 "programmer
" som bare virker om du har tilgang til Microsoft Office,
7988 f.eks. AskiRaski.
</p
>
7990 <p
>Vi sliter også litt med at video-codecer ikke alltid er like lett å
7991 få opp å gå på klientene. Det er alltid en eller annen videosnutt fra
7992 nrk.no som ikke er så samarbeidsvillig, uansett mediaplayer.
</p
>
7994 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
7996 <p
>Alt :-) På skolen bruker vi det som finnes og som er nyttig. Det vi
7997 bruker mest er Firefox (jobber med Chrome, fordi det er
7998 <strong
>mye
</strong
> raskere med Flash enn Firefox), OpenOffice (skal
7999 over til LibreOffice), GIMP osv. Standardpakken av
8000 sluttbrukerprogrammer.
</p
>
8002 <p
>På tjenernivå bruker vi OpenWebMail (skal over til Zimbra), Exim
8005 <p
>Personlig bruker jeg de fleste programmer over flere plattformer,
8006 men jeg har lagt meg til en vane å prioritere bruken av fri
8007 programvare også i Windows
7 og OSX.
</p
>
8009 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
8010 skoler til å ta i bruk fri programvare?
</strong
></p
>
8012 <p
>Jeg er langt i fra sikker. For det første handler det mye om at
8013 IKT-avdelingen i kommunen ofte er de som styrer hva som er IKT på
8014 skolene - og de liker å bruke avtalene med Microsoft, som de garantert
8015 har fra før. Dessuten - Select
6-avtalen til skolene gjør Microsoft
8016 skvettbillig.
</p
>
8018 <p
>Vi la vekt på effektiv drift av systemet - og at vi kunne øke
8019 antall maskiner uten å måtte øke budsjett for utstyr eller personell
8020 særlig mye, enn om vi hadde gått for en Microsoft-løsning. I praksis
8021 ser vi at en ren linux-installasjon driftes til halve prisen av en
8022 Microsoft-løsning.
</p
>
8024 <p
>Vi har i praksis også sett at det lærerne (og elevene) liker er at
8025 vi tilbyr
<strong
>veldig
</strong
> mange tjenester som ikke er så
8026 vanlige i en Microsoft-løsning. Det er ikke så vanlig at
8027 <strong
>elevene
</strong
> også har epost, hjemmekontor osv. Det har vi
8028 også brukt som et vellykket argument mot Microsoft.
</p
>
8030 <p
>Den beste måten er selvfølgelig at noen bare bestemmer
8031 det. Problemet er å få dem som har makt til å bestemme det til faktisk
8032 å gjøre det ;-)

8147 deles til alle. I dag har vi ikke et vitenskapelig tilnærming til
8148 hvordan programvaren som brukes på skolen lages. Skolelinux bringer
8149 inn at slik tilnærming i skoleverkets klasserom, siden
8150 operativsystemet er en åpent platform som gir skolene muligheten til å
8151 dra nytte av programvare som er laget av tusenvis av mennesker verden
8152 rundt og som gir elevene så vel som lærerne muligheten til å bruke,
8153 dele, forandre og forbedre OSet sitt uten begrensninger. I den
8154 forbindelsen representerer Skolelinux også konkrete resultater utfra
8155 samhandling på tvers av grenser.

8157 <p
>Når det gjelder de tekniske fordelene av Skolelinux er jeg sikker
8158 på at andre enn meg har allerede beskrevet disse bedre enn det jeg
8159 kan. Men jeg kan likevel tilføye noe: Skolelinux som sådan er en
8160 community-drevet operativsystemplatform. Som i ethvert
8161 community-prosjekt har alle Skolelinux brukere muligheten til å
8162 påvirke retning av prosjektet og resultatet som gjenspeiles i
8163 programvaren. Dette kommer sjeldent frem og jeg mener at det er noe
8164 som burde fokuseres mer på.

8224 <p
>Skolelinux har jeg møtt ved flere anledninger opp gjennom åra, både gjennom

8227 <p
>Jeg husker en leverandør av et stort OS for noen år siden mente at

8229 kunne ta dette i bruk. Heldigvis er kunnskapen større nå og
8230 skikkelige

8240 <p
>Det største hinderet er det vi opplever på andre områder rundt
8241 fri programvare, nemlig kunnskap. For mange er det trygt å velge det vi
8242 alltid har valgt. Fordi leverandørene rundt oss sitter på den kunnskapen og
8243 de vi støtter oss på har den samme. Hvis vi klarer å riste løs litt og
8244 glemme gamle kriger mellom operativsystemer og leverandører, men sette ned
8245 hva som er viktig og velge ut fra det, så hadde man kanskje kommet ut med
8246 litt andre resultat. Jeg tror IT-folk er konservative og velger tradisjonelt
8247 og det er synd.

8253 som er betalingslisens for er OSX. Ser at jeg jobber mer og mer i
8254 skyen og setter pris på alt jeg slipper egen klient til. Derfor er
8255 jeg veldig sjarmert av små kjappe operativsystemer som krever minimalt
8256 av maskinvaren.

8262 sikkerhet, oppetid og åpne standarder. Informasjon om muligheter og
8263 alternativer. Her har leverandører, IT-avdelinger og pedagoger en vei
8264 å gå sammen. Det er til slutt LÆRING det dreier seg om, og da må man

>Sturle Sunde, ansvarleg for skulenettet i Flora kommune. Eg driv,
8283 vidareutviklar og er andrelinje brukarstøtte for datanettet ved
8284 skulane i Flora kommune.
10 skular og meir enn
700 maskiner med
8285 Linux, medrekna tynnklientar. Tidlegare jobba eg i mange år med
8286 unix-drift ved Universitetets senter for informasjonsteknologi ved
8287 Universitetet i Oslo.
</p
>
8289 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
8291 <p
>Det er vanskeleg å svare konkret på. Eg har drive med Unix og Linux i
8292 alle år, og Skulelinux er eit godt kjent prosjekt i miljøet. Det var
8293 først i
2008, då eg tok til i min noverande jobb, at eg fekk bruk for
8294 Skulelinux for alvor.
</p
>
8296 <p
>Jobben min skulle vere drift av eit nytt skulenett i Flora kommune,
8297 levert av eit firma eg ikkje vil reklamere for. Systemet skulle vere
8298 ferdig levert i september året før. Dette viste seg å ta mykje lenger
8299 tid, og i haustferien
2008 hadde dei endå ikkje klart å få opp ei
8300 fungerande løysing. Situasjonen var prekær for den største skulen i
8301 kommunen med meir enn
500 elevar på ungdomssteget. Skulen hadde brukt
8302 Skulelinux før, og var tilfredse med det. No hadde dei vore utan
8303 fungerande datasystem i nesten eit år. Difor fekk eg opp ein ny tenar
8304 utanfor prosjektet og installerte Skulelinux på den. Etter litt
8305 justering av konfigurasjonen med god hjelp av #skolelinux på IRC, var
8306 den nye tenaren oppe og gjekk med både tynne og halv-tjukke klientar.
8307 Autentisering gjekk mot det nye systemet, slik at elevar og lærarar
8308 framleis har same brukarnamn og passord over alt. Dette berre
8309 fungerte, og vi bestemte oss for å erstatte delar av løysinga vi
8310 skulle få levert med Skulelinux.
</p
>
8312 <p
>Det høyrer med til historia at det nye systemet eg skulle drive frå
8313 januar
2008 endå ikkje er ferdig levert. Dei jobbar med saka, seier
8314 dei, og har von om å fullføre leveransen i løpet av
2011.
</p
>
8316 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
8318 <p
>Det er veldig mange. Eg skal ta nokre få.
</p
>
8320 <p
>Den viktigaste fordelen er at det igrunn berre er ei maskin å passe
8321 på, og det er tenaren. Med andre løysingar har ein gjerne programvare
8322 og anna som skal vedlikehaldast på kvar enkelt maskin. Med Skulelinux
8323 kan alle feil rettast og alle program oppgraderast på alle maskiner
8324 samstundes ved å gjere endringa som må til på tenaren. Eg kan sitje
8325 på kontoret og passe på alle tenarane i kommunen derifrå.
</p
>
8329 <li
>Tynne klientar gjer det mogleg å bruke eldre utstyr lenge, so lenge
8330 tenaren er sterk nok. Ein liten tenar med eit par halv-moderne CPUar
8331 og
2 GiB RAM held lenge for eit typisk klasserom med
30 tynnklientar,
8332 og det er lett å utvide med fleire.
8334 <li
>Halvtjukke klientar gjer det mogleg å utnytte kapasiteten i litt
8335 nyare maskiner betre, og avlaste tenaren. Ingenting vert installert
8336 lokalt på desse heller, og harddisken kan gjerne koblast frå. Gode
8337 halvtjukke klientar kan kjøpast brukt for under
1000-lappen, og det er
8338 heile kostnaden. Ingen lisensar eller anna på toppen, og det er ikkje
8339 krav til kraftigare tenar heller.
8341 <li
>Det er Linux. Vi har ikkje noko kluss med drivarar, dei berre er
8342 der. Heller ikkje med virus, dei finst i realiteten ikkje. Eller med
8343 elevar som klussar med installert programvare, for dei klarar ikkje å
8344 øydeleggje for nokon andre enn seg sjølve.
8348 <p
>Skulelinux er lagt opp til å vere veldig lett å installere rett ut
8349 av boksen på ein heil skule av ein interessert lærar. Det er ofte ei
8350 god løysing for skulen. Å ha nokon til stades som kjenner systemet og
8351 kan forklare enkle ting eller løyse problem der og då, er uvurderleg
8352 viktig for ein stressa lærar fem minutt før det ringer inn.
</p
>
8354 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
8356 <p
>All den ferdige konfigurasjonen gjer det tungvint å tilpasse
8357 Skulelinux til eit system som skal fungere saman med mange andre
8358 installasjonar i eit felles datanett for skulane i ein kommune. Det
8359 heile er prekonfigurert for ein skule, og utviding til mange skular
8360 med eigne tenarar er ikkje berre enkelt.
</p

8362 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
8364 <p
>Eg brukar mest alle små hjelpeprogram som føl med operativsystemet,
8365 samt scriptspråket perl. Elles er Firefox/Iceweasel, Gnome-terminal
8366 og ssh i kontinuerleg bruk. Av Linux-distribusjonar brukar eg både
8367 Debian, Ubuntu, SuSE og RedHat dagleg. Eg prøvar å finne det verktyet
8368 som passar best til kvar del av jobben.

8371 skoler til å ta i bruk fri programvare?
</strong

8373 <p
>Det er to målgrupper ein må sikte mot. Det eine er alle skulane som
8374 manglar eller har eit lite tilfredsstillande opplegg i dag, og ikkje
8375 har råd til å kjøpe noko nytt og blankpussa opplegg. Der er det om å
8376 gjere å gjere det enkelt for skulane å finne Skulelinux, og gjere det
8377 enkelt for dei å få hjelp til installasjon på skulen. Gjerne med
8378 lokale kontaktpersonar. Her er det dugnadsinnsats som må til, for
8379 desse skulane har ikkje råd til å betale for dette.
</p
>
8381 <p
>Den andre og kanskje viktigare målgruppa er dei meir eller mindre
8382 profesjonelle kundane. Alle store offentlege innkjøp, inkludert
8383 innkjøp av nytt datasystem for skular, må ut på offentleg anbod.
8384 Offentlege anbod er mykje meir lukka enn dei gjev inntrykk av, og både
8385 regelboka og boka med triks for å sminke tilbodet er tjukk. Det er
8386 vanskeleg å komme inn utan eit solid salsapparat i ryggen. Kanskje
8387 Skulelinux skulle prøve aktivt å få seg eit partnarskap med eit av dei
8388 store som gjerne vil sterkare inn på den offentlege IT-marknaden?
8389 Nokon som kjenner triksa og har krefter til å ta opp kampen mot både
8390 dårlege anbod og Rudolf Blostrupmoen IT AS. Leveranse til skulane i
8391 ein kommune er ein god måte å få ein fot inn døra som leverandør til
8392 ein lukrativ kommunemarknad som kjøper alle tenester. Ta kontakt med
8393 nokon som er passeleg store og ikkje er Microsoft-partnar, og fortell:
8394 «Vi har eit ferdig produkt som du kan selje. Nei vi skal ikkje ha for
8395 det. Du kan gjerne gjere kva du vil med det, berre vi får lov til å
8396 hjelpe deg. Målgruppa er alle kommunar, og det er noko dei vil ha.
8397 Det er eit godt produkt, brukt av mange og godt likt.»

8423 <p
>Jeg leste en artikkel om en dugnadsinstallasjon av Skolelinux på en
8424 skole på Jæren et sted. Tanken om dugnad og frihet appellerte til
8425 meg. Da vi skulle bygge ny skole var det en del vi måtte spare på,
8426 fordi vi beveget oss mot en kostnadssprekk. Kabling og investering i
8427 PC-er var en av tingene vi sparte på. Derfor kjøpe vi
72 pc-er for
390
8428 pr stk. En filtjener og en applikasjonsserver.

8430 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
8432 <p
>Fordelen er at så mye er satt opp fra starten. I tillegg er det
8433 tydelig at pakka er laga for skoleverket. Brukerne har egne
8434 skrivebord, tilgang på mange gode verktøyprogrammer. Vi slipper å
8435 tenke på virus. Brukerne har ikke mulighet til å ødelegge
8436 klientoppsett, men har gode muligheter til å endre eget oppsett. Dette
8437 tror jeg er inspirerende og kjekt for mange brukere. Mappestrukturen
8438 er ferdig og det er
"enkelt
" å designe lokale mappestrukturer via
8439 skeleton. Noen av oss i skoleverket mener skolen skal være en
8440 "mot-kultur
". Da er Skolelinux et av valgene man kan ta. Et annet er å
8441 spise på indisk restaurant i stedet for Mc Donald
's når vi er på bytur
8442 osv.. Ordene deling, frihet, dugnad osv er positive ord i
8443 skoleverket. Det er viktig at elevene blir bevisst dette.

8445 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
8447 <p
>Kompabiliteten er selvsagt et problem, selv om det er mindre nå enn
8448 før. For IKT-personer på skolene som skal drifte dette er det
8449 problematisk med kommandoer i terminalen. I tillegg er det alt for
8450 mange programmer i Skolelinux som ikke blir brukt. Jeg tror
8451 Skolelinux er tjent med å tone ned begrepet pedagogisk programvare.
8452 Slik jeg ser det finnes ikke denne kategorien programmer lengre slik
8453 de gjorde før, som frittsående programmer som installeres på en
8454 datamaskin eller på serveren. Det finnes en del spesialpedagogiske
8455 programmer, som Textpilot, LingDys, LingRight, AskiRaski, Ny i Norge
8456 osv. Men dette er programmer for enkelt-elever eller små grupper av
8457 elever. Det som bør være fokus er at alle undervisningsressurser som
8458 lages for nettet skal være nettleseruavhengig.

8460 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
8462 <p
>OpenOffice bruker jeg til vanlig kontorarbeide. VLC bruker jeg som
8463 videoavspiller og av og til streaming av film. Gimp bruker jeg i
8464 undervisningen til bildemanipulering. Firefox og Chrome er mine
8465 favoritt-nettlesere. Firefox har lenge vært førstevalget mitt, nå
8466 bruker jeg mest Chrome. Opplever den som raskere og smidigere enn
8467 Firefox. Ubuntu bruker jeg som dualboot på jobb-maskinen min i
8468 tillegg til at alle PCer hjemme har en eller annen Ubuntu-distribusjon
8469 installert. Jeg bruker Clonezilla på Ubuntu
10.04 til kloning av
8470 datamaskiner på jobb. Det er selvsagt en haug andre frie programmer
8471 jeg bruker men jeg bruker dem ikke daglig. Jeg kan ramse opp:
8472 recordmydesktop, cinelerra, acidrip, soundjuicer, audacity, NX
8473 (no-machine), Kino, Rythmbox...

8475 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
8476 skoler til å ta i bruk fri programvare?
</strong
></p
>
8478 <p
>Jeg tror oppsøkende virksomhet er den rette strategien.
8479 Ressurspersoner gjør avtaler med rådmenn, skolesjefer, rektorer. Det
8480 er slik konkurrentene gjør det. Fokuset i slike samtaler bør være
8481 kost-nytte. Dersom personer med økonomisk ansvar ser at de kan få
8482 like godt tilbud til mindre utgifter, tror jeg det er mulighet til å
8483 få innpass. Dersom de også kan få konkrete tilbud på drift i slike
8484 samtaler, vil de kanskje bli litt mer interesserte i hvor mye penger
8485 som faktisk går til IKT i skolene. Det er også viktig at vi ikke
8486 firer for mye på krav til datamaskiner. Det er flott at Skolelinux
8487 går på
"utrangert
" utstyr, men dette bør bare presenteres som et
8488 alternativ. Skolelinux-installasjoner med utrangert utstyr er ikke å
8489 foretrekke dersom man kan unngå det. Det skaper ikke entusiasme hos
8490 brukerne (elever og lærere) når de bruker gamle datamaskiner som går
8491 tregt. Det er kjempefint med skoler som har kommet seg frem til
8492 Skolelinux og fri programvare av seg selv, men de lever på nåde.
8493 Slike valg må fundamenteres hos skoleeier.

8535 virket å være formidabel. Men med hjelp av gode kollegaer og leder
8536 skrev jeg en IKT plan for Narvik kommune som ble vedtatt av politikere
8537 i august
2004. I denne planen ble det bestemt at Narvik kommune skulle
8538 bruke Skolelinux. Her ble det også satt av midler til kabling av god
8539 infrastruktur på alle skoler samt innkjøp av nye datamaskiner. Så i
8540 dag har vi
17 servere hvorav
13 er på Skolelinux, med ca
1500 klienter

>Kommunen min har to omtrent jevnstore tettsteder, og en
8677 ungdomsskole i hvert av tettstedene. Den minste av disse har ca
300
8678 elever og til denne sogner det
3 barneskoler. Den største har ca
350
8679 elever og til denne sogner det
4 barneskoler.
</p
>
8683 <li
>Kommunen har i veldig lang tid forsømt IKT i skolen, og det har
8684 bare blitt gitt smuler i ny og ne. Det er kun den største av
8685 ungdomsskolene som har hatt en skikkelig datapark, og dette takket
8686 være en naturfaglærer som ble lei av å vente på kommunen. Det gjorde
8687 at vi bestemte oss for å ta ting i egne hender, og da vha
8688 skolelinux. En testinstallasjon med
10 gamle PCer ble gjort, og vi så
8689 raskt at dette var veldig lovende. Neste etappe var å gi alle lærere
8690 egen PC på arbeidsplassene sine (
2004), og så sette opp
16 PCer på to
8691 datarom. Vi har kun basert oss på å kjøpe inn brukte maskiner, og
8692 aldri dyrere enn
1000 kr pr klient. For to år siden så hadde vi
8693 klienter i alle klasserom, og totalt hadde vi da rundt
250 stk. Rundt
8694 40 klienter brukes av lærerne og kjører på en egen server. Elvene har
8695 resten, og kjører også en egen server. Servere har vi også kjøpt
8696 brukt,
2 år gamle servere koster
6-
7000 kroner.
</li
>
8698 <li
>Skolen vår er et relativt gammelt bygg, men en meget dyktig
8699 vaktmester har sammen med IKT-ansvarlig/Naturfaglærer lagt kabler til alle
8700 rom. Gradvis har vi byttet ut billige svitsjer med mer solide saker
8701 som er mulig å fjernstyre.
</li
>
8703 <li
>Vi har i all hovedsak greid å få dette til over eget budsjett, men
8704 vi har også passet på å få penger når de andre skolene har fått
8705 bærbare PCer til lærere osv.
</li
>
8707 <li
>Vår IKT-ansvarlig har gjort (og gjør) en fenomenal jobb, og vi har
8708 en maskinpark som de andre av kommunens skoler bare kan drømme
8713 <p
>Så skjer det som ofte skjer. Det kommer en eller annen
8714 selger/blåruss og skal fikse ALT. I vårt tilfelle betyr dette også
8715 sentralisering av drift. Den ny-ansatte på kommunens IT-avdelingen
8716 skal også ha jobb, og ser for seg å ta over skoledriften. Kommunen
8717 kjøper inn eksterne driftstjenester, og nekter i samme slengen å ta
8718 hensyn til skolen vår. Dette til tross for at vi alene har like mange
8719 datamaskiner som de andre til sammen.
</p
>
8723 <li
>Det blir krevd at vi skal innlemmes i de kommunale systemet, og
8724 det er VI som får ansvar for at dette kommer på plass. Og det er her
8725 de horrible tingene begynner å skje.
</li
>
8727 <li
>Det settes opp en lukket Exchange server som gjør av vi ikke kan
8728 hente epost for våre ansatte. Og det kreves at vi finner løsning på
8731 <li
>Det velges sak arkivsystem som vi pålegges å bruke, noe som gjør
8732 at vi må bruke en terminalløsning mot kommunal server. Ikke i seg selv
8733 et problem i følge IKT-ansvarlig hos oss. Men kommunens IT-avd nektet
8734 faktisk å åpne de porter OSV som vi måtte bruke.
</li
>
8736 <li
>Vi blir pålagt å flytte på innsiden av det kommunale
8737 nettverket. Dette gjorde at vi mistet hjemmekontor for lærere og
8738 elever. Å få åpnet porter i kommunal brannmur var ikke
8739 aktuelt. Mulighet for fjerndrift ble også vekk i samme slengen.
</li
>
8741 <li
>Vår LMS Moodle er ikke mulig å nå for elevene og lærerne.
8745 <p
>Den andre ungdomsskolen i kommunen begynner så å kreve at de skal
8746 få bedre datatetthet, og komme opp på et nivå som ligner det vi
8747 har. De ser at vi kan avholde eksamen hvor alle
10. klassingene får
8748 sitte ved hver sin PC. Og de har fått tilbakemelding (klager) fra VGS
8749 om manglende datakompetanse på elevene som kommer fra dem. Dette fører
8750 videre til at kommunen endelig innser at de må ta grep.
</p
>
8752 <p
>Grepet betyr sentralisering, og farvel til vår plattform får vi
8753 høre. Det blir gjort en rekke bestemmelser og vedtak som vi ikke får
8754 være en del av. Det blir helt klart at vi må redusere antall maskiner,
8755 og det skal satses på bærbare maskiner. Siden vi ikke har fått tatt
8756 del i prosessene som angår oss, så bruker vi fagforening. Vi har ikke
8757 blitt hørt i forbindelse med endringer som er betydelig for vår
8758 hverdag, og greier å stoppe omlegging. I tillegg så har vi et politisk
8759 vedtak i kommunen på at vi skal kjøre Linux på elevnett, og dette
8760 vedtaket kan ikke administrasjonen i kommunene helt uten videre
8761 tilsidesette.
</p
>
8763 <p
>I sum har dette gjort at vi har fått jobbe videre i fred. Og en del
8764 runder i kommunens kontrollutvalg har gjort det tydelig at vi har blitt
8765 systematisk motarbeidet.

8768 lærere, men etter
2 år med innkjøring er det fremdeles problemer

8789 men med omgivelsene rundt som vil oss til livs. Men det har vært verdt

8836 har også truet med å si opp jobben sin hvis det ikke ble tatt hensyn i
8837 større grad enn hva som har vært tilfelle. VI kan også dokumentere
8838 flere brudd på anbudsregler, og vi kjenner til at relativt store
8839 IT-leverandører som ikke har fått tatt del i disse anbudene, rett og
8840 slett ikke tør melde fra av redsel for å få et dårlig rykte.

8846 <p
>Jeg glemte å nevne at vi nå nesten ikke bruker tid på å drifte
8847 systemet vårt, noe som gjør at det aller meste av tid blir brukt til å
8848 støtte lærerne og elevene. F.eks så bruker vår IKT-ansvarlig den
8849 første timen på jobb,
0730-
0830 kun til å gå ute på arbeidsplassene
8850 til læreren. Dette for å kunne svare på små og store problem, gi tips
8851 og råd, eller bare for å plukke opp hva som er behovet ute i
8852 undervisningsarealene. Det er dessverre ikke slik at alle lærerne har
8853 nok digital kompetanse til å kunne formulere alle spørsmålene de har,
8854 men ved å kunne få vise eller lufte tanker med IKT-ansvarlig så er det
8855 utrolig hva som kommer fram.
</p
>
8859 <li
>Jeg ser at mange bruker økonomi som argument i forhold til å bruke
8860 SkoleLinux, og jeg skal ikke legge skjul på at det var dette som i
8861 utgangspunktet var årsaken til vårt valg. Men diskusjonene og kampen
8862 med kommunens IT-avdeling har gjort at vi har fått et noe annet
8863 fokus. Fordelene med drift og stabilitet, gjør at vi ville ha valgt
8864 samme løsning selv om den var dyrere. At vi slipper langt billigere
8865 unna, som følge av
0,- lisenskostnader og lave maskinvarekostnader, er
8866 bare en bonus.
</li
>
8868 <li
>Etter å ha kranglet oss til å få skikkelig oversikt over hva de
8869 andre skolene i kommunen bruker på IT, så har vi fått gehør for å få
8870 samme midler til innkjøp. Dette har gjort at vi nå kan kjøpe inn
8871 utstyr som de andre skolene bare kan se langt etter. Vi har nettopp
8872 kjøpt inn
3 videokamera i semiproff-klassen for å kunne lage film,
8873 samt sende live fra skoleteater/konserter. Vi har kjøpt inn digitale
8874 kompaktkamera til alle klassene. Vi har et team av lærere som skal i
8875 gang med å teste ut tablets på svake elever. Håpet et at teknologien
8876 kan være med på å gi noen av elevene litt mer motivasjon. Vi har kjøpt
8877 inn et halvt klassesett med pulsklokker, noe som har vist seg å være
8878 overraskende inspirerende for en del av elevene. Vi har også oss på
8879 fag på en høyskole litt lengre sør for oss, slik at
3 av oss nå skal
8880 ta faget
"Linux tjenestedrift
". Som inspektør og en del av skolens
8881 administrasjon er det veldig praktisk å kunne trå til hvis det
8882 kniper. Men IKT-ansvarlig har vært UTROLIG flink til å lage rene
8883 smørbrødlister for hvordan de mest vanlige driftsproblem løses, så det
8884 er lett for flere av oss å ta del i den daglige driften. Vi har svært
8885 stor nytte av lærling (som også hjelper to av naboskolene), men det er
8886 nesten blitt slik at det er om å gjøre å komme til først for å få løse
8887 problem. Det å få fingrene på problem og utfordringer er den aller
8888 beste læremester.
</li

8892 <p
>Når vi nå tar til med planlegging av ny skole, så vil det være med
8893 tanke på at det skal være mulig med datautstyr på alle plasser. Vi
8894 kommer i all hovedsak til å legge kabel til alle tenkelige og
8895 utenkelige plasser. WiFi koster tilnærmet NULL å sette opp i
8898 <p
>Vi har ikke vært noe flink til å bidra til SkoleLinux-prosjektet,
8899 vi har rett og slett vært for opptatt med vår egen kamp. Vi har hentet
8900 mye inspirasjon fra diskusjoner som har gått i det miljøet, og vi
8901 håper at vi nå framover kan få tid til å bidra. Vi er i ferd med å
8902 bytte ut en av serverne våre, og da vil denne trolig bli satt opp som
8903 testserver for neste versjon av Skolelinux. På den måten vil vi i alle
8904 fall kunne gi tilbakemeldinger og rapportere feil. I tillegg så vil
8905 det kanskje gi oss noen nye utfordringer, for som lærlingen vår sier:

<a
8923 href=
"http://www.uio.no/
">University of Oslo
</a
> testing if the new
8924 batch of computers will work with Linux. Every year for the last few
8925 years the university have organised shared bid of a few thousand
8926 computers, and this year HP won the bid. Two different desktops and
8927 five different laptops are on the list this year. We in the UNIX
8928 group want to know which one of these computers work well with RHEL
8929 and Ubuntu, the two Linux distributions we currently handle at the
8930 university.

8932 <p
>My test method is simple, and I share it here to get feedback and
8933 perhaps inspire others to test hardware as well. To test, I PXE
8934 install the OS version of choice, and log in as my normal user and run
8935 a few applications and plug in selected pieces of hardware. When
8936 something fail, I make a note about this in the test matrix and move
8937 on. If I have some spare time I try to report the bug to the OS
8938 vendor, but as I only have the machines for a short time, I rarely
8939 have the time to do this for all the problems I find.

9034 <title>Why isn

9038 <description><p
>In the latest issue of Linux Journal, the readers choices were
9039 presented, and the winner among the multimedia player were VLC.
9040 Personally, I like VLC, and it is my player of choice when I first try
9041 to play a video file or stream. Only if VLC fail will I drag out
9042 gmplayer to see if it can do better. The reason is mostly the failure
9043 model and trust. When VLC fail, it normally pop up a error message
9044 reporting the problem. When mplayer fail, it normally segfault or
9045 just hangs. The latter failure mode drain my trust in the program.
<p
>
9047 <p
>But even if VLC is my player of choice, we have choosen to use
9048 mplayer in
<a href=
"http://www.skolelinux.org/
">Debian
9049 Edu/Skolelinux
</a
>. The reason is simple. We need a good browser
9050 plugin to play web videos seamlessly, and the VLC browser plugin is
9051 not very good. For example, it lack in-line control buttons, so there
9052 is no way for the user to pause the video. Also, when I
9053 <a href=
"http://wiki.debian.org/DebianEdu/BrowserMultimedia
">last
9054 tested the browser plugins
</a
> available in Debian, the VLC plugin
9055 failed on several video pages where mplayer based plugins worked. If
9056 the browser plugin for VLC was as good as the gecko-mediaplayer
9057 package (which uses mplayer), we would switch.
</P
>
9059 <p
>While VLC is a good player, its user interface is slightly
9060 annoying. The most annoying feature is its inconsistent use of
9061 keyboard shortcuts. When the player is in full screen mode, its
9062 shortcuts are different from when it is playing the video in a window.
9063 For example, space only work as pause when in full screen mode. I
9064 wish it had consisten shortcuts and that space also would work when in
9065 window mode. Another nice shortcut in gmplayer is [enter] to restart
9066 the current video. It is very nice when playing short videos from the
9067 web and want to restart it when new people arrive to have a look at
9068 what is going on.

9836 architecture in Debian as a file server in NUUG to get access to the
5
9837 TB zfs volume we currently use to store DV video. Because of this, I
9838 finally got around to do a test installation of Debian/Squeeze with
9839 kfreebsd. Installation went fairly smooth, thought I noticed some
9840 visual glitches in the cdebconf dialogs (black cursor left on the
9841 screen at random locations). Have not gotten very far with the
9842 testing. Noticed cfdisk did not work, but fdisk did so it was not a
9843 fatal problem. Have to spend some more time on it to see if it is
9844 useful as a file server for NUUG. Will try to find time to set up a
9845 gnash buildbot slave on the Debian Edu/Skolelinux this weekend.

>Prioritising packages for the Debian Edu /
9855 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
> DVD, which is
9856 supposed provide a school with all the services and user applications
9857 needed on the pupils computer network has always been hard. Even
9858 schools without Internet connections should be able to get Debian Edu
9859 working using this DVD.
</p
>
9861 <p
>The job became a lot harder when apt and aptitude started
9862 installing recommended packages by default. We want the same set of
9863 packages to be installed when using the DVD and the netinst CD, and
9864 that means all recommended packages need to be on the DVD. I created
9865 a patch for debian-cd in
<a href=
"http://bugs.debian.org/
601203">BTS
9866 report #
601203</a
> to do this, and since this change was applied to
9867 the Debian Edu DVD build, we have been seriously short on space.
</p
>
9869 <p
>A few days ago we decided to drop blender, wxmaxima and kicad from
9870 the default installation to save space on the DVD, believing that
9871 those needing these applications are few and can get them from the
9872 Debian archive.
</p
>
9874 <p
>Yesterday, I had a look what source packages to see which packages
9875 were using most space. A few large packages are well know;
9876 openoffice.org, openclipart and fluid-soundfont. But I also
9877 discovered that lilypond used
106 MiB and fglrx-driver used
53 MiB.
9878 The lilypond package is pulled in as a dependency for rosegarden, and
9879 when looking a bit closer I discovered that
99 MiB of the
106 MiB were
9880 the documentation package, which is recommended by the binary package.
9881 I decided to drop this documentation package from our DVD, as most of
9882 our users will use the GUI front-ends and do not need the lilypond
9883 documentation. Similarly, I dropped the non-free fglrx-driver package
9884 which might be installed by d-i when its hardware is detected, as the
9885 free X driver should work.
</p
>
9887 <p
>With this change, we finally got space for the LXDE and Gnome
9888 desktop packages as well as the language specific packages making the
9889 DVD more useful again.

9900 <p
>My
<a href=
"http://pledgebank.com/gnash-avm2
">gnash pledge
</a
> to
9901 raise money for the project is going well. The lower limit of
10
9902 signers was reached in
24 hours, and so far
13 people have signed it.
9903 More signers and more funding is most welcome, and I am really curious
9904 how far we can get before the time limit of December
24 is reached.
9907 <p
>On the #gnash IRC channel on irc.freenode.net, I was just tipped
9908 about what appear to be a great code coverage tool capable of
9909 generating code coverage stats without any changes to the source code.
9911 <a href=
"http://simonkagstrom.github.com/kcov/index.html
">kcov
</a
>,
9912 and can be used using
<tt
>kcov
&lt;directory
&gt;
&lt;binary
&gt;
</tt
>.
9913 It is missing in Debian, but the git source built just fine in Squeeze
9914 after I installed libelf-dev, libdwarf-dev, pkg-config and
9915 libglib2.0-dev. Failed to build in Lenny, but suspect that is
9916 solvable. I hope kcov make it into Debian soon.
</p

9918 <p

9923 release. Give it a try if you need a complete linux solution for your
9924 school, including central infrastructure server, workstations, thin
9925 client servers and diskless workstations. A nice touch added
9926 yesterday is RDP support on the thin client servers, for windows
9927 clients to get a Linux desktop on request.

>In the
<a href=
"http://popcon.debian.org/unknown/by_vote
">Debian
9937 popularity-contest numbers
</a
>, the adobe-flashplugin package the
9938 second most popular used package that is missing in Debian. The sixth
9939 most popular is flashplayer-mozilla. This is a clear indication that
9940 working flash is important for Debian users. Around
10 percent of the
9941 users submitting data to popcon.debian.org have this package
9942 installed.
</p

9944 <p
>In the report written by Lars Risan in August
2008
9945 («
<a href=
"http://wiki.skolelinux.no/Dokumentasjon/Rapporter?action=AttachFile
&do=view
&target=Skolelinux_i_bruk_rapport_1.0.pdf
">Skolelinux
9946 i bruk – Rapport for Hurum kommune, Universitetet i Agder og
9947 stiftelsen SLX Debian Labs
</a
>»), one of the most important problems
9948 schools experienced with
<a href=
"http://www.skolelinux.org/
">Debian
9949 Edu/Skolelinux
</a
> was the lack of working Flash. A lot of educational
9950 web sites require Flash to work, and lacking working Flash support in
9951 the web browser and the problems with installing it was perceived as a
9952 good reason to stay with Windows.
</p
>
9954 <p
>I once saw a funny and sad comment in a web forum, where Linux was
9955 said to be the retarded cousin that did not really understand
9956 everything you told him but could work fairly well. This was a
9957 comment regarding the problems Linux have with proprietary formats and
9958 non-standard web pages, and is sad because it exposes a fairly common
9959 understanding of whose fault it is if web pages that only work in for
9960 example Internet Explorer
6 fail to work on Firefox, and funny because
9961 it explain very well how annoying it is for users when Linux
9962 distributions do not work with the documents they receive or the web
9963 pages they want to visit.
</p
>
9965 <p
>This is part of the reason why I believe it is important for Debian
9966 and Debian Edu to have a well working Flash implementation in the
9967 distribution, to get at least popular sites as Youtube and Google
9968 Video to working out of the box. For Squeeze, Debian have the chance
9969 to include the latest version of Gnash that will make this happen, as
9970 the new release
0.8.8 was published a few weeks ago and is resting in
9971 unstable. The new version work with more sites that version
0.8.7.
9972 The Gnash maintainers have asked for a freeze exception, but the
9973 release team have not had time to reply to it yet. I hope they agree
9974 with me that Flash is important for the Debian desktop users, and thus
9975 accept the new package into Squeeze.

10017 har vært rullet ut i noen måneder nå, og så vidt jeg fikk vite før
10018 sommeren skulle alle skoler ha nytt opplegg på plass før oppstart nå i
10019 høst. På alle skolene skal en kunne velge ved installasjon om en skal
10020 ha Windows eller Skolelinux på maskinene, og en kan i tillegg
10021 PXE-boote maskinene over nett som tynne klienter eller diskløse
10022 arbeidsstasjoner. Jeg er spent på hvor mange skoler som velger å ta i
10023 bruk Skolelinux, og gleder meg til å se hvordan dette utvikler seg.
10024 Løsningen leveres av

10149 <description><p
>As reported earlier, the last few days I have looked at how Debian
10150 Edu clients are configured, and tried to get rid of all hardcoded
10151 configuration settings on the clients. I believe the work to be
10152 mostly done, and the clients seem to work just fine with dynamically
10153 generated configuration.
</p
>
10155 <p
>What is the point, you might ask? The point is to allow a Debian
10156 Edu desktop to integrate into an existing network infrastructure
10157 without any manual configuration.
</p
>
10159 <p
>This is what happens when installing a Debian Edu client here at
10160 the University of Oslo using PXE. With the PXE installation, I am
10161 asked for language (Norwegian Bokmål), locality (Norway) and keyboard
10162 layout (no-latin1), Debian Edu profile (Roaming Workstation), if I
10163 accept to reformat the hard drive (yes), if I want to submit info to
10164 popcon.debian.org (no) and root password (secret). After answering
10165 these questions, the installer goes ahead and does its thing, and
10166 after around
50 minutes it is done. I press enter to finish the
10167 installation, and the machine reboots into KDE. When the machine is
10168 ready and kdm asks for login information, I enter my university
10169 username and password, am told by kdm that a local home directory has
10170 been created and that I must log in again, and finally log in with the
10171 same username and password to the KDE
4.4 desktop. At no point during
10172 this process did it ask for university specific settings, and all the
10173 required configuration was dynamically detected using information
10174 fetched via DHCP and DNS. The roaming workstation is now ready for
10177 <p
>How was this done, you might wonder? First of all, here is the
10178 list of things that need to be configured on the client to get it
10179 working properly out of the box:
</p
>
10182 <li
>IP address/netmask and DNS server.
</li
>
10183 <li
>Web proxy URL.
</li
>
10184 <li
>LDAP server for NSS directory information (user, group, etc).
</li
>
10185 <li
>Kerberos server for PAM password checking.
</li
>
10186 <li
>SMB mount point to access the network home directory. (*)
</li
>
10187 <li
>Central syslog server to send syslog messages to. (*)
</li
>
10188 <li
>Sitesummary collector URL to submit info to central server. (*)
</li
>
10191 <p
>(Hm, did I forget anything? Let me knew if I did.)
</p
>
10193 <p
>The points marked (*) are not required to be able to use the
10194 machine, but needed to provide central storage and allowing system
10195 administrators to track their machines. Since yesterday, everything
10196 but the sitesummary collector URL is dynamically discovered at boot
10197 and installation time in the svn version of Debian Edu.
</p
>
10199 <p
>The IP and DNS setup is fetched during boot using DHCP as usual.
10200 When a DHCP update arrives, the proxy setup is updated by looking for
10201 http://wpat/wpad.dat and using the content of this WPAD file to
10202 configure the http and ftp proxy in /etc/environment and
10203 /etc/apt/apt.conf. I decided to update the proxy setup using a DHCP
10204 hook to ensure that the client stops using the Debian Edu proxy when
10205 it is moved outside the Debian Edu network, and instead uses any local
10206 proxy present on the new network when it moves around.
</p
>
10208 <p
>The DNS names of the LDAP, Kerberos and syslog server and related
10209 configuration are generated using DNS information at boot. First the
10210 installer looks for a host named ldap in the current DNS domain. If
10211 not found, it looks for _ldap._tcp SRV records in DNS instead. If an
10212 LDAP server is found, its root DSE entry is requested and the
10213 attributes namingContexts and defaultNamingContext are used to
10214 determine which LDAP base to use for NSS. If there are several
10215 namingContexts attibutes and the defaultNamingContext is present, that
10216 LDAP subtree is used as the base. If defaultNamingContext is missing,
10217 the subtrees listed as namingContexts are searched in sequence for any
10218 object with class posixAccount or posixGroup, and the first one with
10219 such an object is used as the LDAP base. For Kerberos, a similar
10220 search is done by first looking for a host named kerberos, and then
10221 for the _kerberos._tcp SRV record. I
've been unable to find a way to
10222 look up the Kerberos realm, so for this the upper case string of the
10223 current DNS domain is used.
</p
>
10225 <p
>For the syslog server, the hosts syslog and loghost are searched
10226 for, and the _syslog._udp SRV record is consulted if no such host is
10227 found. This algorithm works for both Debian Edu and the University of
10228 Oslo. A similar strategy would work for locating the sitesummary
10229 server, but have not been implemented yet. I decided to fetch and
10230 save these settings during installation, to make sure moving to a
10231 different network does not change the set of users being allowed to
10232 log in nor the passwords required to log in. Usernames and passwords
10233 will be cached by sssd when the user logs in on the Debian Edu
10234 network, and will not change as the laptop move around. For a
10235 non-roaming machine, there is no caching, but given that it is
10236 supposed to stay in place it should not matter much. Perhaps we
10237 should switch those to use sssd too?
</p
>
10239 <p
>The user
's SMB mount point for the network home directory is
10240 located when the user logs in for the first time. The LDAP server is
10241 consulted to look for the user
's LDAP object and the sambaHomePath
10242 attribute is used if found. If it isn
't found, the home directory
10243 path fetched from NSS is used instead. Assuming the path is of the
10244 form /site/server/directory/username, the second part is looked up in
10245 DNS and used to generate a SMB URL of the form
10246 smb://server.domain/username. This algorithm works for both Debian
10247 edu and the University of Oslo. Perhaps there are better attributes
10248 to use or a better algorithm that works for more sites, but this will
10249 do for now. :)
</p
>
10251 <p
>This work should make it easier to integrate the Debian Edu clients
10252 into any LDAP/Kerberos infrastructure, and make the current setup even
10253 more flexible than before. I suspect it will also work for thin
10254 client servers, allowing one to easily set up LTSP and hook it into a
10255 existing network infrastructure, but I have not had time to test this
10258 <p
>If you want to help out with implementing these things for Debian
10259 Edu, please contact us on debian-edu@lists.debian.org.
</p
>
10261 <p
>Update
2010-
08-
09: Simon Farnsworth gave me a heads-up on how to
10262 detect Kerberos realm from DNS, by looking for _kerberos TXT entries
10263 before falling back to the upper case DNS domain name. Will have to
10264 implement it for Debian Edu. :)

10273 <description><p
>A few years ago, I was involved in a project planning to use
10274 Windows file servers as home directory servers for Debian
10275 Edu/Skolelinux machines. This was thought to be no problem, as the
10276 access would be through the SMB network file system protocol, and we
10277 knew other sites used SMB with unix and samba as the file server to
10278 mount home directories without any problems. But, after months of
10279 struggling, we had to conclude that our goal was impossible.
</p
>
10281 <p
>The reason is simply that while SMB can be used for home
10282 directories when the file server is Samba running on Unix, this only
10283 work because of Samba have some extensions and the fact that the
10284 underlying file system is a unix file system. When using a Windows
10285 file server, the underlying file system do not have POSIX semantics,
10286 and several programs will fail if the users home directory where they
10287 want to store their configuration lack POSIX semantics.
</p
>
10289 <p
>As part of this work, I wrote a small C program I want to share
10290 with you all, to replicate a few of the problematic applications (like
10291 OpenOffice.org and GCompris) and see if the file system was working as
10292 it should. If you find yourself in spooky file system land, it might

>A few days ago, I
10505 <a href=
"http://people.skolelinux.org/pere/blog/Debian_Edu_roaming_workstation___at_the_university_of_Oslo.html
">tried
10506 to install
</a
> a Roaming workation profile from Debian Edu/Squeeze
10507 while on the university network here at the University of Oslo, and
10508 noticed how much had to change to get it operational using the
10509 university infrastructure. It was fairly easy, but it occured to me
10510 that Debian Edu would improve a lot if I could get the client to
10511 connect without any changes at all, and thus let the client configure
10512 itself during installation and first boot to use the infrastructure
10513 around it. Now I am a huge step further along that road.
</p
>
10515 <p
>With our current squeeze-test packages, I can select the roaming
10516 workstation profile and get a working laptop connecting to the
10517 university LDAP server for user and group and our active directory
10518 servers for Kerberos authentication. All this without any
10519 configuration at all during installation. My users home directory got
10520 a bookmark in the KDE menu to mount it via SMB, with the correct URL.
10521 In short, openldap and sssd is correctly configured. In addition to
10522 this, the client look for http://wpad/wpad.dat to configure a web
10523 proxy, and when it fail to find it no proxy settings are stored in
10524 /etc/environment and /etc/apt/apt.conf. Iceweasel and KDE is
10525 configured to look for the same wpad configuration and also do not use
10526 a proxy when at the university network. If the machine is moved to a
10527 network with such wpad setup, it would automatically use it when DHCP
10528 gave it a IP address.
</p
>
10530 <p
>The LDAP server is located using DNS, by first looking for the DNS
10531 entry ldap.$domain. If this do not exist, it look for the
10532 _ldap._tcp.$domain SRV records and use the first one as the LDAP
10533 server. Next, it connects to the LDAP server and search all
10534 namingContexts entries for posixAccount or posixGroup objects, and
10535 pick the first one as the LDAP base. For Kerberos, a similar
10536 algorithm is used to locate the LDAP server, and the realm is the
10537 uppercase version of $domain.
</p
>
10539 <p
>So, what is not working, you might ask. SMB mounting my home
10540 directory do not work. No idea why, but suspected the incorrect
10541 Kerberos settings in /etc/krb5.conf and /etc/samba/smb.conf might be
10542 the cause. These are not properly configured during installation, and
10543 had to be hand-edited to get the correct Kerberos realm and server,
10544 but SMB mounting still do not work. :(
</p
>
10546 <p
>With this automatic configuration in place, I expect a Debian Edu
10547 roaming profile installation would be able to automatically detect and
10548 connect to any site using LDAP and Kerberos for NSS directory and PAM
10549 authentication. It should also work out of the box in a Active
10550 Directory environment providing posixAccount and posixGroup objects
10551 with UID and GID values.

>The new roaming workstation profile in Debian Edu/Squeeze is fairly
10564 similar to the laptop setup am I working on using Ubuntu for the
10565 University of Oslo, and just for the heck of it, I tested today how
10566 hard it would be to integrate that profile into the university
10567 infrastructure. In this case, it is the university LDAP server,
10568 Active Directory Kerberos server and SMB mounting from the Netapp file
10571 <p
>I was pleasantly surprised that the only three files needed to be
10572 changed (/etc/sssd/sssd.conf, /etc/ldap.conf and
10573 /etc/mklocaluser.d/
20-debian-edu-config) and one file had to be added
10574 (/usr/share/perl5/Debian/Edu_Local.pm), to get the client working.
10575 Most of the changes were to get the client to use the university LDAP
10576 for NSS and Kerberos server for PAM, but one was to change a hard
10577 coded DNS domain name in the mklocaluser hook from .intern to
10580 <p
>This testing was so encouraging, that I went ahead and adjusted the
10581 Debian Edu scripts and setup in subversion to centralise the roaming
10582 workstation setup a bit more and avoid the hardcoded DNS domain name,
10583 so that when I test this tomorrow, I expect to get away with modifying
10584 only /etc/sssd/sssd.conf and /etc/ldap.conf to get it to use the
10585 university servers.
</p
>
10587 <p
>My goal is to get the clients to have no hardcoded settings and
10588 fetch all their initial setup during installation and first boot, to
10589 allow them to be inserted also into environments where the default
10590 setup in Debian Edu has been changed or as with the university, where

>The last few months me and the other Debian Edu developers have
10721 been working hard to get the Debian/Squeeze based version of Debian
10722 Edu/Skolelinux into shape. This future version will use Kerberos for
10723 authentication, and services are slowly migrated to single signon,
10724 getting rid of password questions one at the time.
</p

10726 <p
>It will also feature a roaming workstation profile with local home
10727 directory, for laptops that are only some times on the Skolelinux
10728 network, and for this profile a shortcut is created in Gnome and KDE
10729 to gain access to the users home directory on the file server. This
10730 shortcut uses SMB at the moment, and yesterday I had time to test if
10731 SMB mounting had started working in KDE after we added the cifs-utils
10732 package. I was pleasantly surprised how well it worked.
</p
>
10734 <p
>Thanks to the recent changes to our samba configuration to get it
10735 to use Kerberos for authentication, there were no question about user
10736 password when mounting the SMB volume. A simple click on the shortcut
10737 in the KDE menu, and a window with the home directory popped

10744 <p

10745 to the autobuilder administrators for some architectures being slow to
10746 sign packages, we are still missing the fixed LTSP package we need for
10747 the release. It was uploaded three days ago with urgency=high, and if
10748 it had entered testing yesterday we would have been able to test it in
10749 time for a alpha0 release today. As the binaries for ia64 and powerpc
10750 still not uploaded to the Debian archive, we need to delay the alpha
10751 release another day.

11095 merged into one while making it impossible to transfer the reverse map
11096 to a slave DNS server.

've written such object class in the dnsdomainaux.schema file (need
11102 proper OIDs, but that is a minor issue), and tested the setup. It
11103 seem to work.

'm
11255 not reporting the status for KDE, because the upgrade crashes when

11263 know what the correct set of packages would be, but thought it best to

11351 <description><p
>For a laptop, centralized user directories and password checking is
11352 a bit troubling. Laptops are typically used also when not connected
11353 to the network, and it is vital for a user to be able to log in or
11354 unlock the screen saver also when a central server is unavailable.
11355 This is possible by caching passwords and directory information (user
11356 and group attributes) locally, and the packages to do so are available
11357 in Debian. Here follow two recipes to set this up in Debian/Squeeze.
11358 It is also possible to set up in Debian/Lenny, but require more manual
11359 setup there because pam-auth-update is missing in Lenny.
</p
>
11361 <h2
>LDAP/Kerberos + nscd + libpam-ccreds + libpam-mklocaluser/pam_mkhomedir
</h2
>
11363 This is the traditional method with a twist. The password caching is
11364 provided by libpam-ccreds (version
10-
4 or later is needed on
11365 Squeeze), and the directory caching is done by nscd. The directory
11366 lookup and password checking is done using LDAP. If one want to use
11367 Kerberos for password checking the libpam-ldapd package can be
11368 replaced with libpam-krb5 or libpam-heimdal. If one is happy having a
11369 local home directory with the path listed in LDAP, one can use the
11370 pam_mkhomedir module from pam-modules to make this happen instead of
11371 using libpam-mklocaluser. A setup for pam-auth-update to enable
11372 pam_mkhomedir will have to be written until a fix for
11373 <a href=
"http://bugs.debian.org/
568577">bug #
568577</a
> is in the
11374 archive. Because I believe it is a bad idea to have local home
11375 directories using misleading paths like /site/server/partition/, I
11376 prefer to create a local user with the home directory in /home/. This
11377 is done using the libpam-mklocaluser package.

've been unable to get TLS

>The last few days I have been looking into the status of the LDAP
11558 directory in Debian Edu, and in the process I started to miss a GUI
11559 tool to browse the LDAP tree. The only one I was able to find in
11560 Debian/Squeeze and Lenny is
11561 <a href=
"http://luma.sourceforge.net/
">LUMA
</a
>, which has proved to
11562 be a great tool to get a overview of the current LDAP directory
11563 populated by default in Skolelinux. Thanks to it, I have been able to
11564 find empty and obsolete subtrees, misplaced objects and duplicate
11565 objects. It will be installed by default in Debian/Squeeze. If you
11566 are working with LDAP, give it a go. :)
</p
>
11568 <p
>I did notice one problem with it I have not had time to report to
11569 the BTS yet. There is no .desktop file in the package, so the tool do
11570 not show up in the Gnome and KDE menus, but only deep down in in the
11571 Debian submenu in KDE. I hope that can be fixed before Squeeze is
11572 released.
</p
>
11574 <p
>I have not yet been able to get it to modify the tree yet. I would
11575 like to move objects and remove subtrees directly in the GUI, but have
11576 not found a way to do that with LUMA yet. So in the mean time, I use
11577 <a href=

11583 <a href=

">gq
</a
> package as a
11584 useful GUI alternative. It seem like a good tool, but is unmaintained
11585 in Debian and got a RC bug keeping it out of Squeeze. Unless that
11586 changes, it will not be an option for Debian Edu based on Squeeze.

11601 <p

11602 the dhcpHost object class auxiliary, to allow it to be combined with

11606 <p

11647 of Debian upgrades

've
11648 finally made the upgrade logs available from
11649 <a href=
"http://people.skolelinux.org/pere/debian-upgrade-testing/
">http://people.skolelinux.org/pere/debian-upgrade-testing/
</a
>.
11650 I am now testing dist-upgrade of Gnome and KDE in a chroot using both
11651 apt and aptitude, and found their differences interesting. This time
11652 I will only focus on their removal plans.
</p
>
11654 <p
>After installing a Gnome desktop and the laptop task, apt-get wants
11655 to remove
72 packages when dist-upgrading from Lenny to Squeeze. The
11656 surprising part is that it want to remove xorg and all
11657 xserver-xorg-video* drivers. Clearly not a good choice, but I am not
11658 sure why. When asking aptitude to do the same, it want to remove
129
11659 packages, but most of them are library packages I suspect are no
11660 longer needed. Both of them want to remove bluetooth packages, which
11661 I do not know. Perhaps these bluetooth packages are obsolete?
</p
>
11663 <p
>For KDE, apt-get want to remove
82 packages, among them kdebase
11664 which seem like a bad idea and xorg the same way as with Gnome. Asking
11665 aptitude for the same, it wants to remove
192 packages, none which are
11666 too surprising.
</p
>
11668 <p
>I guess the removal of xorg during upgrades should be investigated
11669 and avoided, and perhaps others as well. Here are the complete list
11670 of planned removals. The complete logs is available from the URL
11671 above. Note if you want to repeat these tests, that the upgrade test
11672 for kde+apt-get hung in the tasksel setup because of dpkg asking
11673 conffile questions. No idea why. I worked around it by using
11674 '<tt
>echo
>> /proc/
<em
>pidofdpkg
</em
>/fd/
0</tt
>' to tell dpkg to
11675 continue.

11821 <description><p
>The last few days I have done some upgrade testing in Debian, to
11822 see if the upgrade from Lenny to Squeeze will go smoothly. A few bugs
11823 have been discovered and reported in the process
11824 (
<a href=
"http://bugs.debian.org/
585410">#
585410</a
> in nagios3-cgi,
11825 <a href=
"http://bugs.debian.org/
584879">#
584879</a
> already fixed in
11826 enscript and
<a href=
"http://bugs.debian.org/
584861">#
584861</a
> in
11827 kdebase-workspace-data), and to get a more regular testing going on, I
11828 am working on a script to automate the test.
</p
>
11830 <p
>The idea is to create a Lenny chroot and use tasksel to install a
11831 Gnome or KDE desktop installation inside the chroot before upgrading
11832 it. To ensure no services are started in the chroot, a policy-rc.d
11833 script is inserted. To make sure tasksel believe it is to install a
11834 desktop on a laptop, the tasksel tests are replaced in the chroot
11835 (only acceptable because this is a throw-away chroot).
</p
>
11837 <p
>A naive upgrade from Lenny to Squeeze using aptitude dist-upgrade
11838 currently always fail because udev refuses to upgrade with the kernel
11839 in Lenny, so to avoid that problem the file /etc/udev/kernel-upgrade
11840 is created. The bug report
11841 <a href=
"http://bugs.debian.org/
566000">#
566000</a
> make me suspect
11842 this problem do not trigger in a chroot, but I touch the file anyway
11843 to make sure the upgrade go well. Testing on virtual and real
11844 hardware have failed me because of udev so far, and creating this file
11845 do the trick in such settings anyway. This is a
11846 <a href=
"http://www.linuxquestions.org/questions/debian-
26/failed-dist-upgrade-due-to-udev-config_sysfs_deprecated-nonsense-
804130/
">known
11847 issue
</a
> and the current udev behaviour is intended by the udev
11848 maintainer because he lack the resources to rewrite udev to keep
11849 working with old kernels or something like that. I really wish the
11850 udev upstream would keep udev backwards compatible, to avoid such
11851 upgrade problem, but given that they fail to do so, I guess
11852 documenting the way out of this mess is the best option we got for
11853 Debian Squeeze.
</p

11856 script, which I call

>Som systemarkitekten bak Skolelinux, kan jeg bare riste på hodet
11979 over påstanden om at Skolelinux krever desentraliserte tjenere.
11980 Skolelinux-arkitekturen er laget for sentralisert drift og plassering
11981 av tjenerne lokalt eller sentralt alt etter behov og nettkapasitet.
11982 Den er modellert på nettverks- og tjenerløsningen som brukes på
11983 Universitetet i Tromsø og Oslo, der jeg jobber med utvikling av
11984 driftstjenester. Dette er det heldigvis noen som har fått med seg, og
11985 jeg er glad for å kunne sitere fra en kommentar på den overnevnte
11986 artikkelen. Min venn og gamle kollega Sturle Sunde forteller der:
11989 <p
>I Flora kommune køyrer vi Skulelinux på skular med alt frå
15 til
11990 meir enn
500 elevar. Dei store skulane har eigen tenar, for det er
11991 mest praktisk. Eg, som er driftsansvarleg for heile nettet, ser
11992 sjeldan dei tenarane fysisk, men at dei står der gjer skulane mindre
11993 avhengige av eksterne linjer som er trege eller dyre. Dei minste
11994 skulane har ikkje eigen tenar. Å bruke sentral tenar er heller ikkje
11995 noko problem. Småskulane klarar seg fint med
1 mbit-linje til ein
11996 sentral tenar eller tenaren på ein større skule.
</p
>
11998 <p
>Det beste med Skulelinux er halvtjukke klientar. Dei treng ikkje
11999 harddisk og brukar minimalt med ressursar på tenaren fordi dei køyrer
12000 programma lokalt. Eit klasserom med
30 sju-åtte år gamle maskiner har
12001 mykje meir CPU og RAM totalt enn nokon moderne tenar til under
12002 millionen. Det trengst to kommandoar på den sentrale tenaren for å
12003 oppdatere alle klientane, både tynne og halvtjukke. Vi har ingen
12004 problem med diskar som ryk heller, som var eit problem før fordi
12005 elevane sat og sparka i maskinene. Og dei krev lite bandbreidde i
12006 nettet, so det er fullt mogleg å køyre slike på småskular med trege
12007 linjer mot tenaren på ein større skule.
</p
>
12009 <p
>Flora kommune har nesten
800 Linux-maskiner i sitt skulenett, og
12010 ein person som tek seg av drift av heile nettet, inkludert tenarar,
12011 klientar, operativsystem, programvare, heimekontorløysing og
12012 administrasjon av brukarar.
</p
>
12014 <p
>No skal det seiast at vi ikkje køyrer rein Skulelinux ut av
12015 boksen. Vi har gjort ein del tilpassingar mot noko Novell-greier som
12016 var der frå før, og som har komplisert installasjonen vår. Etter at
12017 oppsettet var gjort har løysinga vore stabil og kravd minimalt med

12124 <li

12126 <a href=

12127 parallel booting is enabled. No idea why, but the wicd maintainer
12128 seem to be on the case.

12130 <li
>The nvidia X driver seem to
12131 <a href=

</a

12132 triggered more easily when parallel booting is in effect. The
12133 maintainer is on the case.

12135 <li

12136 sequencing (the shutdown is broken) when old file-rc users
12137 <a href=
"http://bugs.debian.org/

12138 sysv-rc. One way to solve it would be for file-rc to create
12139 /etc/init.d/.legacy-bootordering, and another is to try to make
12140 sysv-rc more robust. Will investigate some more and probably upload a
12141 workaround in sysv-rc to help those trying to move from file-rc to
12142 sysv-rc get a working shutdown.

>After a long break from debian-installer development, I finally
12166 found time today to return to the project. Having to spend less time
12167 working dependency based boot in debian, as it is almost complete now,
12168 definitely helped freeing some time.
</p
>
12170 <p
>A while back, I ran into a problem while working on Debian Edu. We
12171 include some firmware packages on the Debian Edu CDs, those needed to
12172 get disk and network controllers working. Without having these
12173 firmware packages available during installation, it is impossible to
12174 install Debian Edu on the given machine, and because our target group
12175 are non-technical people, asking them to provide firmware packages on
12176 an external medium is a support pain. Initially, I expected it to be
12177 enough to include the firmware packages on the CD to get
12178 debian-installer to find and use them. This proved to be wrong.
12179 Next, I hoped it was enough to symlink the relevant firmware packages
12180 to some useful location on the CD (tried /cdrom/ and
12181 /cdrom/firmware/). This also proved to not work, and at this point I
12182 found time to look at the debian-installer code to figure out what was
12183 going to work.
</p
>
12185 <p
>The firmware loading code is in the hw-detect package, and a closer
12186 look revealed that it would only look for firmware packages outside
12187 the installation media, so the CD was never checked for firmware
12188 packages. It would only check USB sticks, floppies and other
12189 "external
" media devices. Today I changed it to also look in the
12190 /cdrom/firmware/ directory on the mounted CD or DVD, which should
12191 solve the problem I ran into with Debian edu. I also changed it to
12192 look in /firmware/, to make sure the installer also find firmware
12193 provided in the initrd when booting the installer via PXE, to allow us
12194 to provide the same feature in the PXE setup included in Debian
12197 <p
>To make sure firmware deb packages with a license questions are not
12198 activated without asking if the license is accepted, I extended
12199 hw-detect to look for preinst scripts in the firmware packages, and
12200 run these before activating the firmware during installation. The
12201 license question is asked using debconf in the preinst, so this should
12202 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
12215 Edu finally entered the Debian archive. Today, the new
12216 <a href=
"http://packages.qa.debian.org/libp/libpam-mklocaluser.html
">libpam-mklocaluser
</a

12217 package was accepted. Two days ago, two other pieces was accepted
12219 <a href=

12220 package needed by libpam-mklocaluser, and the
12221 <a href=
"http://packages.qa.debian.org/s/sssd.html

12222 passed NEW on Monday. In addition, the
12223 <a href=
"http://packages.qa.debian.org/libp/libpam-ccreds.html
">libpam-ccreds
</a
>
12224 package we need is in experimental (version
10-
4) since Saturday, and
12225 hopefully will be moved to unstable soon.
</p
>
12227 <p
>This collection of packages allow for two different setups for
12228 roaming laptops. The traditional setup would be using libpam-ccreds,
12229 nscd and libpam-mklocaluser with LDAP or Kerberos authentication,
12230 which should work out of the box if the configuration changes proposed
12231 for nscd in
<a href=
"http://bugs.debian.org/
485282">BTS report
12232 #
485282</a
> is implemented. The alternative setup is to use sssd with
12233 libpam-mklocaluser to connect to LDAP or Kerberos and let sssd take
12234 care of the caching of passwords and group information.
</p
>
12236 <p
>I have so far been unable to get sssd to work with the LDAP server
12237 at the University, but suspect the issue is some SSL/GnuTLS related
12238 problem with the server certificate. I plan to update the Debian
12239 package to version
1.2, which is scheduled for next week, and hope to
12240 find time to make sure the next release will include both the
12241 Debian/Ubuntu specific patches. Upstream is friendly and responsive,
12242 and I am sure we will find a good solution.
</p
>
12244 <p
>The idea is to set up the roaming laptops to authenticate using
12245 LDAP or Kerberos and create a local user with home directory in /home/
12246 when a usre in LDAP logs in via KDM or GDM for the first time, and
12247 cache the password for offline checking, as well as caching group
12248 memberhips and other relevant LDAP information. The
12249 libpam-mklocaluser package was created to make sure the local home
12250 directory is in /home/, instead of /site/server/directory/ which would
12251 be the home directory if pam_mkhomedir was used. To avoid confusion
12252 with support requests and configuration, we do not want local laptops
12253 to have users in a path that is used for the same users home directory
12254 on the home directory servers.
</p
>
12256 <p
>One annoying problem with gdm is that it do not show the PAM
12257 message passed to the user from libpam-mklocaluser when the local user
12258 is created. Instead gdm simply reject the login with some generic
12259 message. The message is shown in kdm, ssh and login, so I guess it is
12260 a bug in gdm. Have not investigated if there is some other message
12261 type that can be used instead to get gdm to also show the message.

12418 <description><p
>For some years now, I have wondered how we should handle laptops in
12419 Debian Edu. The Debian Edu infrastructure is mostly designed to
12420 handle stationary computers, and less suited for computers that come
12423 <p
>Now I finally believe I have an sensible idea on how to adjust
12424 Debian Edu for laptops, by introducing a new profile for them, for
12425 example called Roaming Workstations. Here are my thought on this.
12426 The setup would consist of the following:
</p
>
12430 <li
>During installation, the user name of the owner / primary user of
12431 the laptop is requested and a local home directory is set up for
12432 the user, with uid and gid information fetched from the LDAP
12433 server. This allow the user to work also when offline. The
12434 central home directory can be available in a subdirectory on
12435 request, for example mounted via CIFS. It could be mounted
12436 automatically when a user log in while on the Debian Edu network,
12437 and unmounted when the machine is taken away (network down,
12438 hibernate, etc), it can be set up to do automatic mounting on
12439 request (using autofs), or perhaps some GUI button on the desktop
12440 can be used to access it when needed. Perhaps it is enough to use
12441 the fish protocol in KDE?
</li
>
12443 <li
>Password checking is set up to use LDAP or Kerberos
12444 authentication when the machine is on the Debian Edu network, and
12445 to cache the password for offline checking when the machine unable
12446 to reach the LDAP or Kerberos server. This can be done using
12447 <a href=
"http://www.padl.com/OSS/pam_ccreds.html
">libpam-ccreds
</a
>
12448 or the Fedora developed
12449 <a href=
"https://fedoraproject.org/wiki/Features/SSSD
">System
12450 Security Services Daemon
</a
> packages.
</li
>
12452 <li
>File synchronisation with the central home directory is set up
12453 using a shared directory in both the local and the central home
12454 directory, using unison.
</li
>
12456 <li
>Printing should be set up to print to all printers broadcasting
12457 their existence on the local network, and should then work out of
12458 the box with CUPS. For sites needing accurate printer quotas, some
12459 system with Kerberos authentication or printing via ssh could be
12460 implemented.
</li
>
12462 <li
>For users that should have local root access to their laptop,
12463 sudo should be used to allow this to the local user.
</li
>
12465 <li
>It would be nice if user and group information from LDAP is
12466 cached on the client, but given that there are entries for the
12467 local user and primary group in /etc/, it should not be needed.
</li
>
12471 <p
>I believe all the pieces to implement this are in Debian/testing at
12472 the moment. If we work quickly, we should be able to get this ready
12473 in time for the Squeeze release to freeze. Some of the pieces need
12474 tweaking, like libpam-ccreds should get support for pam-auth-update
12475 (
<a href=
"http://bugs.debian.org/
566718">#
566718</a
>) and nslcd (or
12476 perhaps debian-edu-config) should get some integration code to stop
12477 its daemon when the LDAP server is unavailable to avoid long timeouts
12478 when disconnected from the net. If we get Kerberos enabled, we need
12479 to make sure we avoid long timeouts there too.

">Yesterdays
12492 NUUG presentation
</a
> about Kerberos was inspiring, and reminded me
12493 about the need to start using Kerberos in Skolelinux. Setting up a
12494 Kerberos server seem to be straight forward, and if we get this in
12495 place a long time before the Squeeze version of Debian freezes, we
12496 have a chance to migrate Skolelinux away from NFSv3 for the home
12497 directories, and over to an architecture where the infrastructure do
12498 not have to trust IP addresses and machines, and instead can trust
12499 users and cryptographic keys instead.
</p
>
12501 <p
>A challenge will be integration and administration. Is there a
12502 Kerberos implementation for Debian where one can control the
12503 administration access in Kerberos using LDAP groups? With it, the
12504 school administration will have to maintain access control using flat
12505 files on the main server, which give a huge potential for errors.
</p
>
12507 <p
>A related question I would like to know is how well Kerberos and
12508 pam-ccreds (offline password check) work together. Anyone know?
</p
>
12510 <p
>Next step will be to use Kerberos for access control in Lwat and
12511 Nagios. I have no idea how much work that will be to implement. We
12512 would also need to document how to integrate with Windows AD, as such
12513 shared network will require two Kerberos realms that need to cooperate
12514 to work properly.
</p
>
12516 <p
>I believe a good start would be to start using Kerberos on the
12517 skolelinux.no machines, and this way get ourselves experience with
12518 configuration and integration. A natural starting point would be
12519 setting up ldap.skolelinux.no as the Kerberos server, and migrate the
12520 rest of the machines from PAM via LDAP to PAM via Kerberos one at the
12523 <p
>If you would like to contribute to get this working in Skolelinux,
12524 I recommend you to see the video recording from yesterdays NUUG
12525 presentation, and start using Kerberos at home. The video show show
12526 up in a few days.

>6 years ago, as part of the Debian Edu development I am involved
12536 in, I asked for a hook in the kdm and gdm setup to run scripts as root
12537 when the user log out. A bug was submitted against the xfree86-common
12538 package in
2004 (
<a href=
"http://bugs.debian.org/
230422">#
230422</a

12539 and revisited every time Debian Edu was working on a new release.
12540 Today, this finally paid off.
</p
>
12542 <p
>The framework for this feature was today commited to the git
12543 repositry for the xorg package, and the git repository for xdm has
12544 been updated to use this framework. Next on my agenda is to make sure
12545 kdm and gdm also add code to use this framework.
</p
>
12547 <p
>In Debian Edu, we want to ability to run commands as root when the
12548 user log out, to get rid of runaway processes and do general cleanup
12549 after a user. With this framework in place, we finally can do that in
12550 a generic way that work with all display managers using this
12551 framework. My goal is to get all display managers in Debian use it,
12552 similar to how they use the Xsession.d framework today.

>One of the new features in the next Debian/Lenny based release of
12584 Debian Edu/Skolelinux, which is scheduled for release in the next few
12585 days, is automatic configuration of the service monitoring system
12586 Nagios. The previous release had automatic configuration of trend
12587 analysis using Munin, and this Lenny based release take that a step
12590 <p
>When installing a Debian Edu Main-server, it is automatically
12591 configured as a Munin and Nagios server. In addition, it is
12592 configured to be a server for the
12593 <a href=
"http://wiki.debian.org/DebianEdu/HowTo/SiteSummary
">SiteSummary
12594 system
</a
> I have written for use in Debian Edu. The SiteSummary
12595 system is inspired by a system used by the University of Oslo where I
12596 work. In short, the system provide a centralised collector of
12597 information about the computers on the network, and a client on each
12598 computer submitting information to this collector. This allow for
12599 automatic information on which packages are installed on each machine,
12600 which kernel the machines are using, what kind of configuration the
12601 packages got etc. This also allow us to automatically generate Munin
12602 and Nagios configuration.
</p
>
12604 <p
>All computers reporting to the sitesummary collector with the
12605 munin-node package installed is automatically enabled as a Munin
12606 client and graphs from the statistics collected from that machine show
12607 up automatically on http://www/munin/ on the Main-server.
</p
>
12609 <p
>All non-laptop computers reporting to the sitesummary collector are
12610 automatically monitored for network presence (ping and any network
12611 services detected). In addition, all computers (also laptops) with
12612 the nagios-nrpe-server package installed and configured the way
12613 sitesummary would configure it, are monitored for full disks, software
12614 raid status, swap free and other checks that need to run locally on
12615 the machine.
</p
>
12617 <p
>The result is that the administrator on a school using Debian Edu
12618 based on Lenny will be able to check the health of his installation
12619 with one look at the Nagios settings, without having to spend any time
12620 keeping the Nagios configuration up-to-date.
</p
>
12622 <p
>The only configuration one need to do to get Nagios up and running
12623 is to set the password used to get access via HTTP. The system
12624 administrator need to run
"<tt
>htpasswd /etc/nagios3/htpasswd.users
12625 nagiosadmin
</tt
>" to create a nagiosadmin user and set a password for
12626 it to be able to log into the Nagios web pages. After that,
12627 everything is taken care of.

12701 get to know the Skolelinux system. Walter Bender, involved in the

12703 also helped me improve my OLPC installation. He also showed me that
12704 his Turtle Art application can be used in standalone mode, and we

12730 but with the current LDAP schemas it is not possible to have one
12731 object per entity. For example, one need to have at least three LDAP
12732 objects for a given computer, one with the SMB related stuff, one with
12733 DNS information and another with DHCP information. The schemas
12734 provided for DNS and DHCP are impossible to combine into one LDAP
12735 object. In addition, it is impossible to implement quick queries for
12736 netgroup membership, because of the way NIS triples are implemented.
12737 It just do not scale. I believe it is time for a few RFC
12738 specifications to cleam up this mess.

12743 It need to be efficently stored to make sure it scale well.

>Etter flere års mislykkede forsøk på å skrive om byggesystemet for
12780 <a href=
"http://no.speling.org/
">den norske stavekontrollen for bokmål
12781 og nynorsk
</a
> til å ikke bruke bindestrek som ordskillemarkør, lyktes jeg
12782 endelig første juledag. Bruken av bindestrek som ordskillemarkør har
12783 gjort det umulig å få med ord med bindestrek i
12784 stavekontrolldatagrunnlaget, slik at ord som e-post og CD-spiller ikke
12785 kunne godtas av stavekontrollen. Hadde litt tid til overs å bruke på
12786 stavekontrollen, og satte meg ned med to kopier av byggsystemet og en
12787 liten testdatafil, og byttet ut - med = på utvalgte steder i
12788 byggsystemet og datafilen helt til jeg fikk samme resultat med det
12789 gamle og det nye byggsystemet. Dette tror jeg var forsøk
4, der de
12790 foregående har feilet uten at jeg klarte å forstå hvorfor. Det sier
12791 kanskje litt om kompleksiteten i det originale byggsystemet som Rune
12792 Kleveland laget i sin tid.
</p

12794 <p
>Etter å ha endret byggsystemet, var neste steg å importere ordene
12795 med bindestrek. Vi har en rekke slike i databasene for
12796 <a href=

12798 <a href=
"http://tyge.sslug.dk/~korsvoll/nn.speling.org/htdocs/
">nynorsk
</a
>
12799 for korrektur av datagrunnlaget for stavekontrollen, og etter importen
12800 skulle nå
10350 nye ord bli godkjent som korrekt stavede ord av
12801 stavekontrollen.

>This weekend we had a small developer gathering for Debian Edu in
12811 Oslo. Most of Saturday was used for the general assemly for the
12812 member organization, but the rest of the weekend I used to tune the
12813 LTSP installation. LTSP now work out of the box on the
10-network.
12814 Acer Aspire One proved to be a very nice thin client, with both
12815 screen, mouse and keybard in a small box. Was working on getting the
12816 diskless workstation setup configured out of the box, but did not
12817 finish it before the weekend was up.

12819 <p
>Did not find time to look at the
4 VGA cards in one box we got from
12820 the Brazilian group, so that will have to wait for the next
12821 development gathering. Would love to have the Debian Edu installer
12822 automatically detect and configure a multiseat setup when it find one
12823 of these cards.

>Recently I have spent some time evaluating the multimedia browser
12833 plugins available in Debian Lenny, to see which one we should use by
12834 default in Debian Edu. We need an embedded video playing plugin with
12835 control buttons to pause or stop the video, and capable of streaming
12836 all the multimedia content available on the web. The test results and
12837 notes are available on
12838 <a href=
"http://wiki.debian.org/DebianEdu/BrowserMultimedia
">the
12839 Debian wiki
</a
>. I was surprised how few of the plugins are able to
12840 fill this need. My personal video player favorite, VLC, has a really
12841 bad plugin which fail on a lot of the test pages. A lot of the MIME
12842 types I would expect to work with any free software player (like
12843 video/ogg), just do not work. And simple formats like the
12844 audio/x-mplegurl format (m3u playlists), just isn
't supported by the
12845 totem and vlc plugins. I hope the situation will improve soon. No
12846 wonder sites use the proprietary Adobe flash to play video.
