93 imply, public domain and permissively licensed software can lead to
94 the production of more proprietary software as people discover useful
95 software, extend it and or incorporate it into their hardware or
96 software products. Copyleft licenses such as the GNU GPL were created
97 to close off this avenue to the production of proprietary software but
98 such licenses are not enough. With the ongoing adoption of Free
99 Software by individuals and groups, inevitably the community
's
100 expectations of license compliance are violated, usually out of
101 ignorance of the way Free Software works, but not always. As Karen

317 == About Debian Edu / Skolelinux ==
319 Debian Edu, also known as Skolelinux, is a Linux distribution based on
320 Debian providing an out-of-the box environment of a completely
321 configured school network. Directly after installation a school server
322 running all services needed for a school network is set up just
323 waiting for users and machines being added via GOsa², a comfortable
324 Web-UI. A netbooting environment is prepared using PXE, so after
325 initial installation of the main server from CD or USB stick all other
326 machines can be installed via the network. The provided school server
327 provides LDAP database and Kerberos authentication service,
328 centralized home directories, DHCP server, web proxy and many other
329 services. The desktop contains more than
60 educational software
330 packages and more are available from the Debian archive, and schools
331 can choose between KDE, GNOME, LXDE, Xfce and MATE desktop
336 The Debian Project was founded in
1993 by Ian Murdock to be a truly
337 free community project. Since then the project has grown to be one of
338 the largest and most influential open source projects. Thousands of
339 volunteers from all over the world work together to create and
340 maintain Debian software. Available in
70 languages, and supporting a
341 huge range of computer types, Debian calls itself the universal
346 Thanks to everyone making Debian and Debian Edu / Skolelinux happen!

358 computer system for schools I
've involved in,
359 <a href=
"http://www.skolelinux.org/

360 being used in India. But apparently it is, and I managed to get an
361 interview with one of the friends of the project there, Shirish
364 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
366 <p
>My name is Shirish Agarwal. Based out of the educational and
367 historical city of Pune, from the western state of Maharashtra, India.
368 My bread comes from giving training, giving policy tips,
369 installations on free software to mom and pop shops in different
370 fields from Desktop publishing to retail shops as well as work with
371 few software start-ups as well.
</p
>
373 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
374 project?
</strong
></p
>
376 <p
>It started innocently enough. I have been using Debian for a few
377 years and in one local minidebconf / debutsav I was asked if there was
378 anything for schools or education. I had worked / played with free
379 educational softwares such as Gcompris and Stellarium for my many
380 nieces and nephews so researched and found Debian Edu or Skolelinux as
381 it was known then. Since then I have started using the various
382 education meta-packages provided by the project.
</p
>
384 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
385 Edu?
</strong
></p
>
387 <p
>It
's closest I have seen where a package full of educational
388 software are packed, which are free and open (both literally and
389 figuratively). Even if I take the simplest software which is
390 gcompris, the number of activities therein are amazing. Another one of
391 the softwares that I have liked for a long time is stellarium. Even
392 pysycache is cool except for couple of issues I encountered
393 <a href=
"https://bugs.debian.org/
781841">#
781841</a
> and
394 <a href=
"https://bugs.debian.org/
781842">#
781842</a
>.
</p
>
396 <p
>I prefer software installed on the system over web based solutions,
397 as a web site can disappear any time but the software on disk has the
398 possibility of a larger life span. Of course with both it
's more a
399 question if it has enough users who make it fun or sustainable or both
400 for the developer per-se.
</p
>
402 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
403 Edu?
</strong
></p
>
405 <p
>I do see that the Debian Edu team seems to be short-handed and I
406 think more efforts should be made to make it popular and ask and take
407 help from people and the larger community wherever possible.
</p
>
409 <p
>I don
't see any disadvantage to use Skolelinux apart from the fact
410 that most apps. are generic which is good or bad how you see it.
411 However, saying that I do acknowledge the fact that the canvas is
412 pretty big and there are lot of interesting ideas that could be done
413 but for reasons not known not done or if done I don
't know about them.
414 Let me share some of the ideas (these are more upstream based but
415 still) I have had for a long time :
</p
>
417 <p
>1. Classical maths question of two trains in opposing directions
418 each running @x kmph/mph at y distance, when they will meet and how
419 far would each travel and similar questions like these.
421 <p
>The computer is a fantastic system where questions like these can
422 be drawn, animated and the methodology and answers teased out in
423 interactive manner. While sites such as the
424 <a href=
"http://mathforum.org/dr.math/faq/faq.two.trains.html
">Ask
425 Dr. Math FAQ on The Two Trains problem
</a
> (as an example or point of
426 inspiration) can be used there is lot more that can be done. I dunno
427 if there is a free software which does something like this. The idea
428 being a blend of objects + animation + interaction which does
429 this. The whole interaction could be gamified with points or sounds or
430 colourful celebration whenever the user gets even part of the question
431 or/and methodology right. That would help reinforce good behaviour.
432 This understanding could be used to share/showcase everything from how
433 the first wheel came to be, to evolution to how astronomy started,
434 psychics and everything in-between.
</p
>
436 <p
>One specific idea in the train part was having the Linux mascot on
437 one train and the BSD or GNU mascot on the other train and they
438 meeting somewhere in-between. Characters from blender movies could
439 also be used.
</p
>
441 <p
>2. Loads of crossword-puzzles with reference to subjects: We have
442 enormous data sets in Wikipedia and Wikitionary. I don
't think it
443 should be a big job to design crossword puzzles. Using categories and
444 sub-categories it should be doable to have Q
&A single word answers
445 from the existing data-sets. What would make it easy or hard could be
446 the length of the word + existence of many or few vowels depending on
447 the user
's input.
</p
>
449 <p
>3. Jigsaw puzzles - We already have a great software called
450 palapeli with number of slicers making it pretty interesting. What
451 needs to be done is to download large number of public domain and
452 copyleft images, tease and use IPTC tags to categorise them into
453 nature, history etc. and let it loose. This could turn to be really
454 huge collection of images. One source could be taken from
455 commons.wikimedia.org, others could be huge collection of royalty-free
456 stock photos. Potential is immense.

>Apart from this, free software suffers in two directions, we lag
459 both in development (of using new features per-se) and maintenance a
460 lot. This is more so in educational software as these applications
461 need to be timely and the opportunity cost of missing deadlines is
462 immense. If we are able to solve issues of funding for development and
463 maintenance of such software I don
't see any big difficulties. I know
464 of few start-ups in and around India who would love to develop and
465 maintain such software if funding issues could be solved.

469 <p
>That would be huge list. Some of the softwares are obviously apt,
470 aptitude, debdelta, leafpad, the shell of course (zsh nowadays),
471 quassel for IRC. In games I use shisen-sho while card-games are evenly
472 between kpat and Aiselriot. In desktops it
's a tie between
473 gnome-flashback and mate.

478 <p

479 whatever environment they are. If it
's MS-Windows or Mac so be it.
480 Once they are habitual with the apps. and there is buy-in from the
481 school management then it could be installed anywhere. Most of the
482 people now understand the concept of a repository because of the
483 various online stores so it isn
't hard to convince on that front.

491 instance, Debian has this whole range of fonts in its archive but
492 there isn

495 <p
>One of the issues faced constantly in installations is with updates
496 and upgrades. People have this myth that each update and upgrade
497 means the user interface will / has to change. I have seen this
498 innumerable times. That perhaps is one of the reasons which browsers
499 like Iceweasel / Firefox change user interfaces so much, not because
500 it might be needed or be functional but because people believe that
501 changed user interfaces are better. This, can easily be pointed with

551 The Debian Edu Team is pleased to announce the release of Debian Edu
552 Jessie
8.0+edu0~alpha0
554 Debian Edu is a complete operating system for schools. Through its
555 various installation profiles you can install servers, workstations
556 and laptops which will work together on the school network. With
557 Debian Edu, the teachers themselves or their technical support can
558 roll out a complete multi-user multi-machine study environment within
559 hours or a few days. Debian Edu comes with hundreds of applications
560 pre-installed, but you can always add more packages from Debian.
562 For those who want to give Debian Edu Jessie a try, download and
563 installation instructions are available, including detailed
564 instructions in the manual[
1] explaining the first steps, such as
565 setting up a network or adding users. Please note that the password
566 for the user your prompted for during installation must have a length
567 of at least
5 characters!

's computer a longer life? Are you
572 tired of sneaker administration, running from computer to computer
573 reinstalling the operating system? Would you like to administrate all
574 the computers in your school using only a couple of hours every week?
575 Check out Debian Edu Jessie!
577 Skolelinux is used by at least two hundred schools all over the world,
578 mostly in Germany and Norway.
580 About Debian Edu and Skolelinux
581 ===============================
583 Debian Edu, also known as Skolelinux[
2], is a Linux distribution based
584 on Debian providing an out-of-the box environment of a completely
585 configured school network. Immediately after installation a school
586 server running all services needed for a school network is set up just
587 waiting for users and machines being added via GOsa², a comfortable
588 Web-UI. A netbooting environment is prepared using PXE, so after
589 initial installation of the main server from CD or USB stick all other
590 machines can be installed via the network. The provided school server
591 provides LDAP database and Kerberos authentication service,
592 centralized home directories, DHCP server, web proxy and many other
593 services. The desktop contains more than
60 educational software
594 packages[
3] and more are available from the Debian archive, and
595 schools can choose between KDE, Gnome, LXDE, Xfce and MATE desktop

736 boot of both clients without disk and the installation to install Debian
737 Edu on machines with disk (and a few other services perhaps to small
738 to mention here). We in the Debian Edu team are currently working on
739 the Jessie based version, trying to get everything in shape before the
740 freeze, to avoid having to maintain our own package repository in the
742 <a href=
"https://wiki.debian.org/DebianEdu/Status/Jessie

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

">http
</a
>
752 ftp.skolelinux.org::cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-
1.iso).
753 The ISO build was broken on Tuesday, so we do not get a new ISO every
754 12 hours or so, but thankfully the ISO we already got we are able to
755 install with some tweaking.
</p
>
757 <p
>When you get to the Debian Edu profile question, go to tty2
758 (use Alt-Ctrl-F2), run
</p
>
760 <p
><blockquote
><pre
>
761 nano /usr/bin/edu-eatmydata-install
762 </pre
></blockquote
></p
>
764 <p
>and add
'exit
0' as the second line, disabling the eatmydata
765 optimization. Return to the installation, select the profile you want
766 and continue. Without this change, exim4-config will fail to install
767 due to a known bug in eatmydata.
</p
>
769 <p
>When you get the grub question at the end, answer /dev/sda (or if
770 this do not work, figure out what your correct value would be. All my
771 test machines need /dev/sda, so I have no advice if it do not fit
774 <p
>If you installed a profile including a graphical desktop, log in as
775 root after the initial boot from hard drive, and install the
776 education-desktop-XXX metapackage. XXX can be kde, gnome, lxde, xfce
777 or mate. If you want several desktop options, install more than one
778 metapackage. Once this is done, reboot and you should have a working
779 graphical login screen. This workaround should no longer be needed
780 once the education-tasks package version
1.801 enter testing in two
783 <p
>I believe the ISO build will start working on two days when the new
784 tasksel package enter testing and Steve McIntyre get a chance to
785 update the debian-cd git repository. The eatmydata, grub and desktop
786 issues are already fixed in unstable and testing, and should show up
787 on the ISO as soon as the ISO build start working again. Well the
788 eatmydata optimization is really just disabled. The proper fix
789 require an upload by the eatmydata maintainer applying the patch
790 provided in bug
<a href=
"https://bugs.debian.org/
702711">#
702711</a
>.
791 The rest have proper fixes in unstable.
</p
>
793 <p
>I hope this get you going with the installation testing, as we are
794 quickly running out of time trying to get our Jessie based
795 installation ready before the distribution freeze in a month.

<a href=

805 a lot quicker. When we install more than
2000 packages in
806 <a href=
"http://www.skolelinux.org/
">Skolelinux / Debian Edu
</a
> using
807 tasksel in the installer, unpacking the binary packages take forever.
808 A part of the slow I/O issue was discussed in
809 <a href=
"https://bugs.debian.org/
613428">bug #
613428</a
> about too
810 much file system sync-ing done by dpkg, which is the package
811 responsible for unpacking the binary packages. Other parts (like code
812 executed by postinst scripts) might also sync to disk during
813 installation. All this sync-ing to disk do not really make sense to
814 me. If the machine crash half-way through, I start over, I do not try
815 to salvage the half installed system. So the failure sync-ing is
816 supposed to protect against, hardware or system crash, is not really
817 relevant while the installer is running.
</p
>
819 <p
>A few days ago, I thought of a way to get rid of all the file
820 system sync()-ing in a fairly non-intrusive way, without the need to
821 change the code in several packages. The idea is not new, but I have
822 not heard anyone propose the approach using dpkg-divert before. It
823 depend on the small and clever package
824 <a href=
"https://packages.qa.debian.org/eatmydata
">eatmydata
</a
>, which
825 uses LD_PRELOAD to replace the system functions for syncing data to
826 disk with functions doing nothing, thus allowing programs to live
827 dangerous while speeding up disk I/O significantly. Instead of
828 modifying the implementation of dpkg, apt and tasksel (which are the
829 packages responsible for selecting, fetching and installing packages),
830 it occurred to me that we could just divert the programs away, replace
831 them with a simple shell wrapper calling
832 "eatmydata
&nbsp;$program
&nbsp;$@
", to get the same effect.
833 Two days ago I decided to test the idea, and wrapped up a simple
834 implementation for the Debian Edu udeb.
</p
>
836 <p
>The effect was stunning. In my first test it reduced the running
837 time of the pkgsel step (installing tasks) from
64 to less than
44
838 minutes (
20 minutes shaved off the installation) on an old Dell
839 Latitude D505 machine. I am not quite sure what the optimised time
840 would have been, as I messed up the testing a bit, causing the debconf
841 priority to get low enough for two questions to pop up during
842 installation. As soon as I saw the questions I moved the installation
843 along, but do not know how long the question were holding up the
844 installation. I did some more measurements using Debian Edu Jessie,
845 and got these results. The time measured is the time stamp in
846 /var/log/syslog between the
"pkgsel: starting tasksel
" and the
847 "pkgsel: finishing up
" lines, if you want to do the same measurement
848 yourself. In Debian Edu, the tasksel dialog do not show up, and the
849 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
899 time is spent downloading packages. The connection to the Internet
900 was
100Mbit/s during testing, so downloading should not be a
901 significant factor in the measurement. Download typically took a few
902 seconds to a few minutes, depending on the amount of packages being
905 <p
>The speedup is implemented by using two hooks in
906 <a href=
"https://www.debian.org/devel/debian-installer/
">Debian
907 Installer
</a
>, the pre-pkgsel.d hook to set up the diverts, and the
908 finish-install.d hook to remove the divert at the end of the
909 installation. I picked the pre-pkgsel.d hook instead of the
910 post-base-installer.d hook because I test using an ISO without the
911 eatmydata package included, and the post-base-installer.d hook in
912 Debian Edu can only operate on packages included in the ISO. The
913 negative effect of this is that I am unable to activate this
914 optimization for the kernel installation step in d-i. If the code is
915 moved to the post-base-installer.d hook, the speedup would be larger
916 for the entire installation.

1029 involved is Bernd Zeitzen, who show up on the project mailing lists
1030 from time to time with interesting questions and tips on how to adjust
1031 the setup. I managed to interview him this summer.
</p

1035 <p
>My name is Bernd Zeitzen and I
'm married with Hedda, a self
1036 employed physiotherapist. My former profession is tool maker, but I
1037 haven
't worked for
30 years in this job.
30 years ago I started to
1038 support my wife and become her officeworker and a few years later the
1039 administrator for a small computer network, today based on Ubuntu
1040 Server (Samba, OpenVPN). For her daily work she has to use Windows
1041 Desktops because the software she needs to organize her business only
1042 works with Windows . :-(
</p
>
1044 <p
>In
1988 we started with one PC and DOS, then I learned to use
1045 Windows
98,
2000, XP, …,
8, Ubuntu, MacOSX. Today we are running a
1046 Linux server with
6 Windows clients and
10 persons (teacher of
1047 children with special needs, speech therapist, occupational therapist,
1048 psychologist and officeworkers) using our Samba shares via OpenVPN to
1049 work with the documentations of our patients.

1051 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
1052 project?
</strong
></p
>
1054 <p
>Two years ago a friend of mine asked me, if I want to get a job in
1055 his school (
<a href=
"http://www.gymnasium-harsewinkel.de/
">Gymnasium
1056 Harsewinkel
</a
>). They started with Skolelinux / Debian Edu and they
1057 were looking for people to give support to the teachers using the
1058 software and the network and teaching the pupils increasing their
1059 computer skills in optional lessons. I
'm spending
4-
6 hours a week
1060 with this job.
</p
>
1062 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
1063 Edu?
</strong
></p
>
1065 <p
>The independence.
</p
>
1067 <p
>First: Every person is allowed to use, share and develop the
1068 software. Even if you are poor, you are allowed to use the software
1069 included in Skolelinux/Debian Edu and all the other Free Software.
</p
>
1071 <p
>Second: The software runs on old machines and this gives us the
1072 possibility to recycle computers, weeded out from offices. The
1073 servers and desktops are running for more than two years and they are
1074 working reliable.
</p
>
1076 <p
>We have two servers (one tjener and one terminal server),
45
1077 workstations in three classrooms and seven laptops as a mobile
1078 solution for all classrooms. These machines are all booting from the
1079 terminal server. In the moment we are installing
30 laptops as mobile
1080 workstations. Then the pupils have the possibility to work with these
1081 machines in their classrooms. Internet access is realized by a WLAN
1082 router, connected to the schools network. This is all done without a
1083 dedicated system administrator or a computer science teacher.
</p

1085 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
1086 Edu?
</strong
></p
>
1088 <p
>Teachers and pupils are Windows users.
&lt;Irony on
&gt; And Linux
1089 isn
't cool. It
's software for freaks using the command line.
&lt;Irony
1090 off
&gt; They don
't realize the stability of the system.
</p
>
1092 <p
><strong
>Which free software do you use daily?
</strong
></p
>
1094 <p
>Firefox, Thunderbird, LibreOffice, Ubuntu Server
12.04 (Samba,
1095 Apache, MySQL, Joomla!, … and Skolelinux / Debian Edu)
</p
>
1097 <p
><strong
>Which strategy do you believe is the right one to use to
1098 get schools to use free software?
</strong
></p
>
1100 <p
>In Germany we have the situation: every school is free to decide
1101 which software they want to use. This decision is influenced by
1102 teachers who learned to use Windows and MS Office. They buy a PC with
1103 Windows preinstalled and an additional testing version of MS
1104 Office. They don
't know about the possibility to use Free Software
1105 instead. Another problem are the publisher of school books. They
1106 develop their software, added to the school books, for Windows.

>The
<a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
1116 project
</a
> provide an instruction manual for teachers, system
1117 administrators and other users that contain useful tips for setting up
1118 and maintaining a Debian Edu installation. This text is about how the
1119 text processing of this manual is handled in the project.
</p
>
1121 <p
>One goal of the project is to provide information in the native
1122 language of its users, and for this we need to handle translations.
1123 But we also want to make sure each language contain the same
1124 information, so for this we need a good way to keep the translations
1125 in sync. And we want it to be easy for our users to improve the
1126 documentation, avoiding the need to learn special formats or tools to
1127 contribute, and the obvious way to do this is to make it possible to
1128 edit the documentation using a web browser. We also want it to be
1129 easy for translators to keep the translation up to date, and give them
1130 help in figuring out what need to be translated. Here is the list of
1131 tools and the process we have found trying to reach all these
1134 <p
>We maintain the authoritative source of our manual in the
1135 <a href=
"https://wiki.debian.org/DebianEdu/Documentation/Wheezy/
">Debian
1136 wiki
</a
>, as several wiki pages written in English. It consist of one
1137 front page with references to the different chapters, several pages
1138 for each chapter, and finally one
"collection page
" gluing all the
1139 chapters together into one large web page (aka
1140 <a href=
"https://wiki.debian.org/DebianEdu/Documentation/Wheezy/AllInOne
">the
1141 AllInOne page
</a
>). The AllInOne page is the one used for further
1142 processing and translations. Thanks to the fact that the
1143 <a href=
"http://moinmo.in/
">MoinMoin
</a
> installation on
1144 wiki.debian.org support exporting pages in
1145 <a href=
"http://www.docbook.org/
">the Docbook format
</a
>, we can fetch
1146 the list of pages to export using the raw version of the AllInOne
1147 page, loop over each of them to generate a Docbook XML version of the
1148 manual. This process also download images and transform image
1149 references to use the locally downloaded images. The generated
1150 Docbook XML files are slightly broken, so some post-processing is done
1151 using the
<tt
>documentation/scripts/get_manual
</tt
> program, and the
1152 result is a nice Docbook XML file (debian-edu-wheezy-manual.xml) and
1153 a handfull of images. The XML file can now be used to generate PDF, HTML
1154 and epub versions of the English manual. This is the basic step of
1155 our process, making PDF (using dblatex), HTML (using xsltproc) and
1156 epub (using dbtoepub) version from Docbook XML, and the resulting files
1157 are placed in the debian-edu-doc-en binary package.
</p
>
1159 <p
>But English documentation is not enough for us. We want translated
1160 documentation too, and we want to make it easy for translators to
1161 track the English original. For this we use the
1162 <a href=
"http://packages.qa.debian.org/p/poxml.html
">poxml
</a
> package,
1163 which allow us to transform the English Docbook XML file into a
1164 translation file (a .pot file), usable with the normal gettext based
1165 translation tools used by those translating free software. The pot
1166 file is used to create and maintain translation files (several .po
1167 files), which the translations update with the native language
1168 translations of all titles, paragraphs and blocks of text in the
1169 original. The next step is combining the original English Docbook XML
1170 and the translation file (say debian-edu-wheezy-manual.nb.po), to
1171 create a translated Docbook XML file (in this case
1172 debian-edu-wheezy-manual.nb.xml). This translated (or partly
1173 translated, if the translation is not complete) Docbook XML file can
1174 then be used like the original to create a PDF, HTML and epub version
1175 of the documentation.
</p
>
1177 <p
>The translators use different tools to edit the .po files. We
1179 <a href=
"http://www.kde.org/applications/development/lokalize/
">lokalize
</a
>,
1180 while some use emacs and vi, others can use web based editors like
1181 <a href=
"http://pootle.translatehouse.org/
">Poodle
</a
> or
1182 <a href=
"https://www.transifex.com/
">Transifex
</a
>. All we care about
1183 is where the .po file end up, in our git repository. Updated
1184 translations can either be committed directly to git, or submitted as
1185 <a href=
"https://bugs.debian.org/src:debian-edu-doc
">bug reports
1186 against the debian-edu-doc package
</a
>.
</p
>
1188 <p
>One challenge is images, which both might need to be translated (if
1189 they show translated user applications), and are needed in different
1190 formats when creating PDF and HTML versions (epub is a HTML version in
1191 this regard). For this we transform the original PNG images to the
1192 needed density and format during build, and have a way to provide
1193 translated images by storing translated versions in
1194 images/$LANGUAGECODE/. I am a bit unsure about the details here. The
1195 package maintainers know more.
</p
>
1197 <p
>If you wonder what the result look like, we provide
1198 <a href=
"http://maintainer.skolelinux.org/debian-edu-doc/
">the content
1199 of the documentation packages on the web
</a

1203 HTML version

1204 but perhaps it will be done in the future.

1224 wish to contribute, and I managed to get a interview with this great
1225 contributor Roger Marsal to learn more about his background.
</p

1227 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p

1229 <p
>My name is Roger Marsal, I
'm
27 years old (
1986 generation) and I
1230 live in Barcelona, Spain. I
've got a strong business background and I
1231 work as a patrimony manager and as a real estate agent. Additionally,
1232 I
've co-founded a British based tech company that is nowadays on the
1233 last development phase of a new social networking concept.
</p

1235 <p
>I
'm a Linux enthusiast that started its journey with Ubuntu four years
1236 ago and have recently switched to Debian seeking rock solid stability
1237 and as a necessary step to gain expertise.
</p

1239 <p
>In a nutshell, I spend my days working and learning as much as I
1240 can to face both my job, entrepreneur project and feed my Linux
1243 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
1244 project?
</strong
></p
>
1246 <p
>I discovered the
<a href=
"http://www.ltsp.org/
">LTSP
</a
> advantages
1247 with
"Ubuntu
12.04 alternate install
" and after a year of use I
1248 started looking for an alternative. Even though I highly value and
1249 respect the Ubuntu project, I thought it was necessary for me to
1250 change to a more robust and stable alternative. As far as I was using
1251 Debian on my personal laptop I thought it would be fine to install
1252 Debian and configure an LTSP server myself. Surprised, I discovered
1253 that the Debian project also supported a kind of Edubuntu equivalent,
1254 and after having some pain I obtained a Debian Edu network up and
1255 running. I just loved it.
</p
>
1257 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
1258 Edu?
</strong
></p
>
1260 <p
>I found a main advantage in that, once you know
"the tips and
1261 tricks
", a new installation just works out of the box. It
's the most
1262 complete alternative I
've found to create an LTSP network. All the
1263 other distributions seems to be made of plastic, Debian Edu seems to
1264 be made of steel.

1266 <p

1267 Edu?
</strong

>
1269 <p
>I found two main disadvantages.
</p
>
1271 <p
>I
'm not an expert but I
've got notions and I had to spent a considerable
1272 amount of time trying to bring up a standard network topology. I
'm quite
1273 stubborn and I just worked until I did but I
'm sure many people with few
1274 resources (not big schools, but academies for example) would have switched
1275 or dropped.
</p
>
1277 <p
>It
's amazing how such a complex system like Debian Edu has achieved
1278 this out-of-the-box state. Even though tweaking without breaking gets
1279 more difficult, as more factors have to be considered. This can
1280 discourage many people too.

1282 <p

1291 <p
>I don
't think there is a need for a particular strategy. The free
1292 attribute in both
"freedom
" and
"no price
" meanings is what will
1293 really bring free software to schools. In my experience I can think of
1294 the
<a href=
"http://www.r-project.org/

</a
>; a
1295 few years a ago was an extremely nerd tool for university people.
1296 Today it
's being increasingly used to teach statistics at many
1297 different level of studies. I believe free and open software will
1298 increasingly gain popularity, but I
'm sure schools will be one of the
1299 first scenarios where this will happen.

"http://www.slxdrift.no/
">Skolelinux Drift AS
</a
>, where I am
1315 on the board of directors, asked about how to do this. The steps to
1316 get this working are the following:
</p
>
1320 <li
>Add new storage server in DNS. I use nas-server.intern as the
1321 example host here.
</li
>
1323 <li
>Add automoun LDAP information about this server in LDAP, to allow
1324 all clients to automatically mount it on reqeust.
</li
>
1326 <li
>Add the relevant entries in tjener.intern:/etc/fstab, because
1327 tjener.intern do not use automount to avoid mounting loops.
</li
>
1329 </ol
></p
>
1331 <p
>DNS entries are added in GOsa², and not described here. Follow the
1332 <a href=
"https://wiki.debian.org/DebianEdu/Documentation/Wheezy/GettingStarted
">instructions
1333 in the manual
</a
> (Machine Management with GOsa² in section Getting
1336 <p
>Ensure that the NFS export points on the server are exported to the
1337 relevant subnets or machines:

1340 root@tjener:~# showmount -e nas-server
1341 Export list for nas-server:
1344 </pre
></blockquote

>
1346 <p
>Here everything on the backbone network is granted access to the
1347 /storage export. With NFSv3 it is slightly better to limit it to
1348 netgroup membership or single IP addresses to have some limits on the
1349 NFS access.
</p
>
1351 <p
>The next step is to update LDAP. This can not be done using GOsa²,
1352 because it lack a module for automount. Instead, use ldapvi and add
1353 the required LDAP objects using an editor.

1355 <p

></blockquote
></p
>
1359 <p
>When the editor show up, add the following LDAP objects at the
1360 bottom of the document. The
"/
&" part in the last LDAP object is a
1361 wild card matching everything the nas-server exports, removing the
1362 need to list individual mount points in LDAP.

1399 was able to get an interview with a newcomer in the project who showed
1400 up on the IRC channel a few weeks ago to let us know about his
1401 successful installation of Debian Edu Wheezy in his School. Say hello
1402 to
<a href=

1407 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
1409 <p
>I am a
23 year-old student from Germany who has spent half of his
1410 life with open source. In
"real life
", I am, as already mentioned, a
1411 student in the fields of Computer Science, Electrical Engineering,
1412 Information Technologies and Anglistics. Due to my (only partially
1413 voluntary) huge engagement in the open source world, these things are
1414 a bit vacant right now however.
</p
>
1416 <p
>I also have been working as a project teacher at a Gymasnium
1417 (public school) for various years now. I took up that work some time
1418 around
2005 when still attending that school myself and have continued
1419 it until today. I also had been running the (kind of very advanced)
1420 network of that school together with a team of very interested and
1421 talented students in the age of
11 to
15 years, who took the chance to
1422 learn a lot about open source and networking before I left the school
1423 to help building another school
's informational education concept from
1426 <p
>That said, one might see me as a kind of
"glue
" between school kids
1427 and the elderly of teachers as well as between the open source
1428 ecosystem and the (even more complex) educational ecosystem.
</p
>
1430 <p
>When I am not busy with open source or education, I like Geocaching
1431 and cycling.
</p
>
1433 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
1434 project?
</strong
></p
>
1436 <p
>I think that happened some time around
2009 when I first attended
1437 <a href=
"http://www.froscon.org
">FrOSCon
</a
> and visited the project
1438 booth. I think I wasn
't too interested back then because I used to
1439 have an attitude of disliking software that does too much stuff on its
1440 own. Maybe I was too inexperienced to realise the upsides of an
1441 "out-of-the-box
" solution ;).
</p
>
1443 <p
>The first time I actively talked to Skolelinux people was at
1444 <a href=
"http://www.openrheinruhr.de
">OpenRheinRuhr
</a
> 2011 when the
1445 BiscuIT project, a home-grewn software used by my school for various
1446 really cool things from timetables and class contact lists to lunch
1447 ordering, student ID card printing and project elections first got to
1448 a stage where it could have been published. I asked the Skolelinux
1449 guys running the booth if the project were interested in it and gave a
1450 small demonstration, but there wasn
't any real feedback and the guys
1451 seemed rather uninterested.
</p
>
1453 <p
>After I left the school where I developed the software, it got
1454 mostly lost, but I am now reimplementing it for my new school. I have
1455 reusability and compatibility in mind, and I hop there will be a new
1456 basis for contributing it to the Skolelinux project ;)!
</p
>
1458 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
1459 Edu?
</strong
></p
>
1461 <p
>The most important advantage seems to be that it
"just
1462 works
". After overcoming some minor (but still very annoying) glitches
1463 in the installer, I got a fully functional, working school network,
1464 without the month-long hassle I experienced when setting all that up
1465 from scratch in earlier years. And above that, it rocked - I didn
't
1466 have any real hardware at hand, because the school was just founded
1467 and has no money whatsoever, so I installed a combined server (main
1468 server, terminal services and workstation) in a VM on my personal
1469 notebook, bridging the LTSP network interface to the ethernet port,
1470 and then PXE-booted the Windows notebooks that were lying around from
1471 it. I could use
8 clients without any performance issues, by using a
1472 tiny little VM on a tiny little notebook. I think that
's enough to say
1473 that it rocks!
</p
>
1475 <p
>Secondly, there are marketing reasons. Life
's bad, and so no
1476 politician will ever permit a setup described as
"Debian, an universal
1477 operating system, with some really cool educational tools
" while they
1478 will be jsut fine with
"Skolelinux, a single-purpose solution for your
1479 school network
", even if both turn out to be the very same thing (yes,
1480 this is unfair towards the Skolelinux project, and must not be taken
1481 too seriously - you get the idea, anyway).
</p
>
1483 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
1484 Edu?
</strong
></p
>
1486 <p
>I have not been involved with Skolelinux long enough to really
1487 answer this question in a fair way. Thus, please allow me to put it in
1488 other words:
"What do you expect from Skolelinux to keep liking it?
" I
1489 can list a few points about that:
</p
>
1493 <li
>always strive to get all things integrated into Debian upstream
1494 <li
>be open to discussion about changes and the like, even with newcomers
1495 <li
>be helpful at being helpful ;)
1499 <p
>I
'm really sorry I cannot say much more about that :(!
</p
>
1501 <p
><strong
>Which free software do you use daily?
</strong
></p
>
1503 <p
>First of all, all software I use is free and open. I have abandoned
1504 all non-free software (except for firmware on my darned phone) this
1507 <p
>I run Debian GNU/Linux on all PC systems I use. On that, I mostly
1508 run text tools. I use
1509 <a href=
"https://www.mirbsd.org/mksh.htm
">mksh
</a
> as shell,
1510 <a href=
"https://www.mirbsd.org/jupp.htm
">jupp
</a
> as very advanced
1511 text editor (I even got the developer to help me write a script/macro
1512 based full-featured student management software with the two),
1513 <a href=
"http://mcabber.com/
">mcabber
</a
> for XMPP and
1514 <a href=
"http://www.irssi.org/
">irssi
</a
> for IRC. For that overly
1515 coloured world called the WWW, I use
1516 <a href=
"https://www.mozilla.org/en-US/firefox/new/
">Iceweasel
1517 (Firefox)
</a
>. Oh, and
<a href=
"http://www.mutt.org/
">mutt
</a
> for
1520 <p
>However, while I am personally aware of the fact that text tools
1521 are more efficient and powerful than anything else, I also use (or at
1522 least operate) some tools that are suitable to bring open source to
1523 kids. One of these things is
<a href=
"http://jappix.org/
">Jappix
</a
>,
1524 which I already introduced to some kids even before they got aware of
1525 Facebook, making them see for themselves that they do not need
1526 Facebook now ;).
</p
>
1528 <p
><strong
>Which strategy do you believe is the right one to use to
1529 get schools to use free software?
</strong
></p
>
1531 <p
>Well, that
's a two-sided thing. One side is what I believe, and one
1532 side is what I have experienced.
</p
>
1534 <p
>I believe that the right strategy is showing them the benefits. But
1535 that won
't work out as long as the acceptance of free alternatives
1536 grows globally. What I mean is that if all the kids are almost forced
1537 to use Windows, Facebook, Skype, you name it at home, they will not
1538 see why they would want to use alternatives at school. I have seen
1539 students take seat in front of a fully-functional, modern Debian
1540 desktop that could do anything their Windows at home could do, and
1541 they jsut refused to use it because
"Linux sucks
". It is something
1542 that makes the council of our city spend around
600000 € to buy
1543 software - not including hardware, mind you - for operating school
1544 networks, and for installing a system that, as has been proved, does
1545 not work. For those of you readers who are good at maths, have you
1546 already found out how many lives could have been saved with that money
1547 if we had instead used it to bring education to parts of the world
1548 that need it? I have, and found it to be nothing less dramatic than
1549 plain criminal.
</p
>
1551 <p
>That said, the only feasible way appears to be the bottom up
1552 method. We have to bring free software to kids and parents. I have
1553 founded an association named
1554 <a href=
"https://www.teckids.org
">Teckids
</a
> here in Germany that does
1555 just that. We organise several events for kids and adolescents in the
1556 area of free and open source software, for example the
1557 <a href=
"http://kids.froscon.org
">FrogLabs
</a
>, which share staff with
1558 Teckids and are the youth programme of
1559 <a href=
"http://www.froscon.org
">the Free and Open Source Software
1560 Conference (FrOSCon)
</a
>. We do a lot more than most other conferences
1561 - this year, we first offered the FrogLabs as a holiday camp for kids
1562 aged
10 to
16. It was a huge success, with approx.
30 kids taking part
1563 and learning with and about free software through a whole weekend. All
1564 of us had a lot of fun, and the results were really exciting.
</p
>
1566 <p
>Apart from that, we are preparing a campaign that is supposed to bring
1567 the message of free alternatives to stuff kids use every day to them and
1568 their parents, e.g. the use of Jabber / Jappix instead of Facebook and
1569 Skype. To make that possible, we are planning to get together a team of
1570 clever kids who understand very well what their peers need and can bring
1571 it across to them. So we will have a peer-driven network of adolescents
1572 who teach each other and collect feedback from the community of minors.
1573 We then take that feedback and our own experience to work closely with
1574 open source projects, such as Skolelinux or Jappix, at improving their
1575 software in a way that makes it more and more attractive for the target
1576 group. At least I hope that we will have good cooperation with
1577 Skolelinux in the future ;)!
</p
>
1579 <p
>So in conclusion, what I believe is that, if it weren
't for the world
1580 being so bad, it should be very clear to the political decision makers
1581 that the only way to go nowadays is free software for various reasons,
1582 but I have learnt that the only way that seems to work is bottom up.
</p
>
1586 > * Who should be interviewed with this questions in the future?
1588 That
's probably the hardest question of them all, as I do not know the
1589 community. However, I would be willing to do the following:
1591 <li
>Run an interview with a German headteacher who is very open to
1592 free software, and also prefers it, but cannot really use it because
1593 of the decision makers above;
1594 <li
>Run interviews with some kids, both with and without previous
1595 knowledge about free software
1597 If that is wanted, just let me know ;).

1660 <li
>Skolelinux is - as we had to learn - not easily upgradable to
1661 the next version. Opposed to its genuine Debian base, upgrading to
1662 a new version means a full new installation from scratch to get it
1663 working again reliably.
1665 <li
>Skolelinux is based on Debian/stable, and therefore always a
1666 little outdated in terms of program versions compared to Edubuntu or
1667 similar educational Linux distros, which rather use Debian/testing
1670 <li
>Skolelinux has some very self-opinionated and stubborn default
1671 configuration which in my opinion adds unnecessary complexity and is
1672 not always suitable for a schools needs, the preset network
1673 configuration is actually a core definition feature of Skolelinux
1674 and not easy to change, so schools sometimes have to change their
1675 network configuration to make it
"Skolelinux-compatible
".
1677 <li
>Some proposed extensions, which were made available as
1678 contribution, like secure examination mode and lecture material
1679 distribution and collection, were not accepted into the mainline
1680 Skolelinux development and are now not easy to maintain in the
1681 future because of Skolelinux somewhat undeterministic update
1684 <li
>Skolelinux has only a very tiny number of base developers
1685 compared to Debian.
</li
>
1689 <p
>For these reasons and experience from our project, I would now
1690 rather consider using plain Debian for schools next time, until
1691 Skolelinux is more closely integrated into Debian and becomes
1692 upgradeable without reinstallation.

>A few hours ago, the announcement for the first stable release of
1765 Debian Edu Wheezy went out from the Debian publicity team. The
1766 complete announcement text can be found at
1767 <a href=
"http://www.debian.org/News/

1768 section
</a

</p
>
1770 <p
>There is one minor known problem that we will fix very soon. One
1771 can not install a amd64 Thin Client Server using PXE, as the /var/
1772 partition is too small. A workaround is to extend the partition (use
1773 lvresize + resize2fs in tty
2 while installing).

>About Debian Edu and Skolelinux
</p
>
1853 <p
>Debian Edu, also known as Skolelinux, is a Linux distribution based
1854 on Debian providing an out-of-the box environment of a completely
1855 configured school network. Immediately after installation a school
1856 server running all services needed for a school network is set up just
1857 waiting for users and machines being added via GOsa², a comfortable
1858 Web-UI. A netbooting environment is prepared using PXE, so after
1859 initial installation of the main server from CD or USB stick all other
1860 machines can be installed via the network. The provided school server
1861 provides LDAP database and Kerberos authentication service,
1862 centralized home directories, DHCP server, web proxy and many other
1863 services. The desktop contains more than
60 educational software
1864 packages and more are available from the Debian archive, and schools
1865 can choose between KDE, Gnome, LXDE and Xfce desktop environment.
</p
>
1867 <p
>This is the seventh test release based on Debian Wheezy. Basically
1868 this is an updated and slightly improved version compared to the
1869 Squeeze release.
</p
>
1871 <p
>Notes for upgrades from Alpha Prereleases
</p
>
1873 <p
>Alpha based installations should reinstall or downgrade the
1874 versions of gosa and libpam-mklocaluser to the ones used in this beta
1875 release. Both alpha and beta0 based installations should reinstall or
1876 deal with gosa.conf manually; there are two options: (
1) Keep
1877 gosa.conf and edit this file as outlined on the mailing list. (
2)
1878 Accept the new version of gosa.conf and replace both contained admin
1879 password placeholders with the password hashes found in the old one
1880 (backup copy!). In both cases all users need to change their password
1881 to make sure a password is set for CIFS access to their home
1882 directory.

2193 <p
><a href=
"http://www.skolelinux.org/
">Debian Edu, also known as
2194 Skolelinux
</a
>, is a Linux distribution based on Debian providing an
2195 out-of-the box environment of a completely configured school
2196 network. Immediately after installation a school server running all
2197 services needed for a school network is set up just waiting for users
2198 and machines being added via GOsa², a comfortable Web-UI. A netbooting
2199 environment is prepared using PXE, so after initial installation of
2200 the main server from CD, DVD or USB stick all other machines can be
2201 installed via the network. The provided school server provides LDAP
2202 database and Kerberos authentication service, centralized home
2203 directories, DHCP server, web proxy and many other services. The
2205 <a href=
"http://people.skolelinux.org/pere/blog/Educational_applications_included_in_Debian_Edu___Skolelinux__the_screenshot_collection____.html
">more
2206 than
60 educational software packages
</a
> and more are available from
2207 the Debian archive, and schools can choose between KDE, Gnome, LXDE
2208 and Xfce desktop environment.
</p
>
2210 <p
>This is the fourth test release based on Debian Wheezy. Basically
2211 this is an updated and slightly improved version compared to the
2212 Squeeze release.
</p
>
2214 <p
><strong
>Software updates
</strong
></p
>
2216 <li
>Dropped ispell dictionaries from our default installation.
</li
>
2217 <li
>Dropped menu-xdg from the KDE desktop option, to drop the Debian
2218 submenu. It was not included with Gnome, LXDE or Xfce, so this
2219 brings KDE in line with the others.
</li
>
2220 <li
>Dropped xdrawchem, xjig and xsok from our default installation as
2221 they don
't have a desktop menu entry and thus won
't show up in the
2222 menu now that menu-xdg was removed.
</li
>
2223 <li
>Removed the killer system to kill left behind processes on
2224 multi-user machines, as it was no longer able to understand when a
2225 X display was in use and killed the processes of the active users
2227 <li
>Dropped the golearn (from goplay) package as the debtags in wheezy
2228 are too few to make the package useful.
</li
>
2230 <p
><strong
>Other changes
</strong
></p
>
2232 <li
>Updated artwork matching http://wiki.debian.org/DebianArt/Themes/Joy
2233 <li
>Multi-arch i386/amd64 USB stick ISO available.
</li
>
2234 <li
>Got rid of ispell/wordlist related debconf questions that showed
2235 up for some language options.
</li
>
2236 <li
>Switched to using http.debian.net as APT source by default.
</li
>
2237 <li
>Fixed proxy configuration on Main Server installations.
</li
>
2238 <li
>Changed LTSP setup to ask dpkg to use force-unsafe-io the same way
2239 d-i is doing it.
</li
>
2240 <li
>Made sure root and user passwords were not left behind in the
2241 debconf database after installation on Main Server installations.
</li
>
2242 <li
>Made Roaming Workstation dynamic setup more robust and added draft
2243 script setup-ad-client to hook a Roaming Workstation up to a
2244 Active Directory server instead of a Debian Edu Main Server.
</li
>
2245 <li
>Update system to install needed firmware packages during
2246 installation, to work properly in Wheezy.
</li
>
2247 <li
>Update system to handle hardware quirks (debian-edu-hwsetup).
</li
>
2248 <li
>Corrected PXE installation setup to properly pass selected desktop
2249 and keymap settings to PXE installation clients.
</li
>
2250 <li
>LTSP diskless workstations use sshfs by default, allowing them to
2251 work without adding them to DNS and NIS netgroups for NFS access.

2292 <description><p
>In the
<a href=
"http://www.skolelinux.org/
">Debian Edu /
2293 Skolelinux
</a
> project, we include a post-installation test suite,
2294 which check that services are running, working, and return the
2295 expected results. It runs automatically just after the first boot on
2296 test installations (using test ISOs), but not on production
2297 installations (using non-test ISOs). It test that the LDAP service is
2298 operating, Kerberos is responding, DNS is replying, file systems are
2299 online resizable, etc, etc. And it check that the PXE service is
2300 configured, which is the topic of this post.
</p
>
2302 <p
>The last week I
've fixed the DVD and USB stick ISOs for our Debian
2303 Edu Wheezy release. These ISOs are supposed to be able to install a
2304 complete system without any Internet connection, but for that to
2305 happen all the needed packages need to be on them. Thanks to our test
2306 suite, I discovered that we had forgotten to adjust our PXE setup to
2307 cope with the new names and paths used by the netboot d-i packages.
2308 When Internet connectivity was available, the installer fall back to
2309 using wget to fetch d-i boot images, but when offline it require
2310 working packages to get it working. And the packages changed name
2311 from debian-installer-
6.0-netboot-$arch to
2312 debian-installer-
7.0-netboot-$arch, we no longer pulled in the
2313 packages during installation. Without our test suite, I suspect we
2314 would never have discovered this before release. Now it is fixed
2315 right after we got the ISOs operational.
</p
>
2317 <p
>Another by-product of the test suite is that we can ask system
2318 administrators with problems getting Debian Edu to work, to run the
2319 test suite using
<tt
>/usr/sbin/debian-edu-test-install
</tt
> and see if
2320 any errors are detected. This usually pinpoint the subsystem causing
2321 the problem.

">our IRC channel
2341 #debian-edu

</strong
></p

2348 <p
>I
'm a
25 year old free software enthusiast, living in Romania,
2349 which is also my country of origin. Back in
2009, at a New Year
's Eve
2350 party, I had a very nice
<strike
>beer
</strike
> discussion with a
2351 friend, when we realized we have no organised Debian community in our
2352 country. A few days later, we put together the infrastructure for such
2353 community and even gathered a nice Debian-ish crowd. Since then, I
2354 began my quest as a free software hacker and activist and I am
2355 constantly trying to cover as much ground as possible on that
2358 <p
>A few years ago I founded a small web development company, which
2359 provided me the flexible schedule I needed so much for my
2360 activities. For the last
13 months, I have been the Technical Director
2361 of
<a href=
"http://ceata.org/
">Fundația Ceata
</a
>, which is a free
2362 software activist organisation endorsed by the FSF and the FSFE, and
2363 the only one we have in our country.
</p
>
2365 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
2366 project?
</strong
></p
>
2368 <p
>The idea of participating in the Debian Edu project was a surprise
2369 even to me, since I never used it before I began getting involved in
2370 it. This year I had a great opportunity to deliver a talk on
2371 educational software, and I knew immediately where to look. It was a
2372 love at first sight, since I was previously involved with some of the
2373 technologies the project incorporates, and I rapidly found a lot of
2374 ways to contribute.
</p
>
2376 <p
>My first contributions consisted in translating the installer and
2377 configuration dialogs, then I found some bugs to squash (I still
2378 haven
't fixed them yet though), and I even got my eyes on some other
2379 areas where I can prove myself helpful. Since the appetite for free
2380 software in my country is pretty low, I
'll be happy to be the first
2381 one around here advocating for the project
's adoption in educational
2382 environments, and maybe even get my hands dirty in creating a flavour
2383 for our own needs. I am not used to make very advanced plannings, so
2384 from now on, time will tell what I
'll be doing next, but I think I
2385 have a pretty consistent starting point.
</p

2387 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
2388 Edu?
</strong
></p
>
2390 <p
>Not a long time ago, I was in the position of configuring and
2391 maintaining a LDAP server on some Debian derivative, and I must say it
2392 took me a while. A long time ago, I was maintaining a bigger
2393 Samba-powered infrastructure, and I must say I spent quite a lot of
2394 time on it. I have similar stories about many of the services included
2395 with Skolelinux, and the main advantage I see about it is the
2396 out-of-the box availability of them, making it quite competitive when
2397 it comes to managing a school
's network, for example.
</p
>
2399 <p
>Of course, there is more to say about Skolelinux than the
2400 availability of the software included, its flexibility in various
2401 scenarios is something I can
't wait to experiment
"into the wild
" (I
2402 only played with virtual machines so far). And I am sure there is a
2403 lot more I haven
't discovered yet about it, being so new within the
2406 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
2407 Edu?
</strong
></p
>
2409 <p
>As usual, when it comes to Debian Blends, I see as the biggest
2410 disadvantage the lack of a numerous team dedicated to the
2411 project. Every day I see the same names in the changelogs, and I have
2412 a constantly fear of the bus factor in this story. I
'd like to see
2413 Debian Edu advertised more as an entry point into the Debian
2414 ecosystem, especially amongst newcomers and students. IMHO there are a
2415 lot low-hanging fruits in terms of bug squashing, and enough
2416 opportunities to get the feeling of the Debian Project
's dynamics. Not
2417 to mention it
's a very fun blend to work on!
</p
>
2419 <p
>Derived from the previous statement, is the delay in catching up
2420 with the main Debian release and documentation. This is common though
2421 to all blends and derivatives, but it
's an issue we can all work
2424 <p
><strong
>Which free software do you use daily?
</strong
></p
>
2426 <p
>I can hardly imagine myself spending a day without Vim, since my
2427 daily routine covers writing code and hacking configuration files. I
2428 am a fan of the Awesome window manager (but I also like the
2429 Enlightenment project a lot!),
2430 <a href=
"http://www.claws-mail.org/
">Claws Mail

> due to its ease of
2431 use and very configurable behaviour. Recently I fell in love with
2432 <a href=
"https://launchpad.net/redshift
">Redshift
</a
>, which helps me
2433 get through the night without headaches. Of course, there is much more
2434 stuff in this bag, but I
'll need a blog on my own for doing this!

2436 <p
><strong
>Which strategy do you believe is the right one to use to
2437 get schools to use free software?
</strong
></p
>
2439 <p
>Well, on this field, I cannot do much more than experiment right
2440 now. So, being far from having a recipe for success, I can only assume
2445 <li
>schools would like to get rid of proprietary software
</li
>
2447 <li
>students will love the openness of the system, and will want to
2448 experiment with it - maybe we need to harvest the native curiosity
2449 of teenagers more?
</li
>
2451 <li
>there is no
"right one
" when it comes to strategies, but it would
2452 be useful to have some success stories published somewhere, so
2453 other can get some inspiration from them (I know I
'd promote
2456 <li
>more active promotion - talks, conferences, even small school
2457 lectures can do magical things if they encounter at least one
2458 person interested. Who knows who that person might be? ;-)
</li
>
2462 <p
>I also see some problems in getting Skolelinux into schools; for
2463 example, in our country we have a great deal of corruption issues, so
2464 it might be hard(er) to fight against proprietary solutions. Also,
2465 people who relied on commercial software for all their lives, would be
2466 very hard to convert against their will.

2500 it was great getting input from people who have been around longer. I
2501 was also still very excitable and said yes to everything and to this
2502 day I have a big todo list backlog that I
'm catching up with. I think
2503 over the years the relationship between Edubuntu and Debian-Edu has
2504 been gradually improving, although I think there
's a lot that we could
2505 still improve on in terms of working together on packages. I
'm sure
2506 we
'll get there one day.

2511 <p
>Debian itself already has so many advantages. I could go on about
2512 it for pages, but in essence I love that it
's a very honest project
2513 that puts its users first with no hidden agendas and also produces
2514 very high quality work.
</p

2516 <p
>I think the advantage of Debian Edu is that it makes many common
2517 set-up tasks simpler so that administrators can get up and running
2518 with a lot less effort and frustration. At the same time I think it
2519 helps to standardise installations in schools so that it
's easier for
2520 community members and commercial suppliers to support.

2525 <p

'm trying to
2526 separate
"disadvantages
" from
"areas that need improvement
" (which is
2527 what I originally rambled on about)
</p
>
2529 <p
>The biggest disadvantage I can think of is lack of manpower. The
2530 project could do so much more if there were more good contributors. I
2531 think some of the problems are external too. Free software and free
2532 content in education is a no-brainer but it takes some time to catch
2533 on. When you
've been working with the same proprietary eco-system for
2534 years and have gotten used to it, it can be hard to adjust to some
2535 concepts in the free software world. It would be nice if there were
2536 more Debian Edu consultants across the world. I
'd love to be one
2537 myself but I
'm already so over-committed that it
's just not possible
2538 currently.
</p
>
2540 <p
>I think the best short-term solution to that large-scale problem is
2541 for schools to be pro-active and share their experiences and grow
2542 their skills in-house. I
'm often saddened to see how much money
2543 educational institutions spend on
3rd party solutions that they don
't
2544 have access to after the service has ended and they could
've gotten so
2545 much more value otherwise by being more self-sustainable and
2546 autonomous.

2550 <p
>My main laptop dual-boots between Debian and Windows
7. I was
2551 Windows free for years but started dual-booting again last year for
2552 some games which help me focus and relax (Starcraft II in
2553 particular). Gaming support on Linux is improving in leaps and bounds
2554 so I suppose I
'll soon be able to regain that disk space :)

2556 <p
>Besides that I rely on Icedove, Chromium, Terminator, Byobu, irssi,
2557 git, Tomboy, KVM, VLC and LibreOffice. Recently I
've been torn on
2558 which desktop environment I like and I
'm taking some refuge in Xfce
2559 while I figure that out. I like tools that keep things simple. I enjoy
2560 Python and shell scripting. I went to an Arduino workshop recently and
2561 it was awesome seeing how easy and simple the IDE software was to get

2583 some areas of the world rely heavily on very specific versions of MS

2585 general concepts. I think that
's very unproductive because firstly, MS
2586 Office
's interface changes drastically every few years and on top of
2587 that it also locks in a generation to a product that might not be the
2588 best solution for them.

">Debian Edu, also known as
2613 Skolelinux
</a
>, is a Linux distribution based on Debian providing an
2614 out-of-the box environment of a completely configured school
2615 network. Immediately after installation a school server running all
2616 services needed for a school network is set up just waiting for users
2617 and machines being added via GOsa², a comfortable Web-UI. A netbooting
2618 environment is prepared using PXE, so after initial installation of
2619 the main server from CD, DVD or USB stick all other machines can be
2620 installed via the network. The provided school server provides LDAP
2621 database and Kerberos authentication service, centralized home
2622 directories, DHCP server, web proxy and many other services. The

2786 <p

2787 ready to use, which can and the nice administration interface provided
2788 by

2789 me also was the fact that among the software installed by default,
2790 there were many
"traditional

2807 fact that it provides a solution ready to use.

2816 <p
>Maybe the lack of manpower to do lobbying on the
2817 project. Sometimes, people who need to take decisions concerning IT do
2818 not have all the elements to evaluate properly free software
2819 solutions. The fact that support by a company may be difficult to find
2820 is probably a problem if the school does not have IT personnel.

2822 <p

"http://wiki.debian.org/DebianEdu/Help/ProfessionalHelp

2825 companies providing support for Debian Edu, like Germany or
2826 Norway. This list is easy to find readily from the manual. However,
2827 for other countries, like France, the list is empty. I guess that
2828 consultants proposing support for Debian would be able to provide some
2829 support for Debian Edu as well.

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

3044 <p
>Jeg heter Nirosan Thiyagalingam. Jeg er
24 år og studerer
3045 dataingeniør studiet ved Høgskolen i Sør Trøndelag. Interessen for
3046 data har siden ung alder vært tilstede og jeg har i tillegg alltid
3047 vært glad i å lære nye ting. Med teknologi som endres svært hurtig er
3048 det alltid noe nytt å lære. Noe som igjen har gjort det svært
3049 interessant å følge med på utviklingen. Jeg valgte dataingeniør
3050 studiet grunnet ønske om å lære enda mer om programmering og utvikling
3051 av store systemer.
</p
>
3053 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
3055 <p
>Skolelinux prosjektet hørte jeg først om i media. Men det var først
3056 når jeg skulle velge bacheloroppgave at jeg fattet mer interesse for
3057 prosjektet. Et enkelt søk på nettet førte meg til skolelinux sine
3058 hjemmesider. Informasjonen jeg fant der gjorde meg enda nysgjerrig og
3059 jeg valgte derfor en oppgave som gikk ut på å få en
3060 <a href=
"http://www.raspberrypi.org
">Raspberry PI
</a
>. Altså en
3061 ultra-billig datamaskin til å kjøre Debian Edu på lik linje med
3062 vanlige datamaskiner. I løpet av prosjektet ble det gjort mye
3063 forskning på nettet. Det var mye jeg måtte forstå rundt hvordan
3064 operativsystemet Linux fungerte før jeg kunne angripe
3065 problemet. Prøvde først å finne ut hvordan man kunne transformere en
3066 vanlig installasjon av Skolelinux til Raspberry PI, men dette var
3067 altfor vanskelig å jeg endte opp med mer spørsmål enn svar. Det ble
3068 videre opprettet kontakt med Skolelinux utviklere på IRC der jeg fikk
3069 diskutert hvilken retning jeg burde gå for å få til en fullverdig
3070 løsning. Det ble bestemt at jeg skulle gå for å først installere
3071 <a href=
"http://www.raspbian.org/
">Raspian
</a
>. Dette er et
3072 operativsystem basert på Debian spesiallaget for Raspberry Pi sin
3073 maskinvare. Nå som Debian var installert på datamaskinen gjenstod det
3074 å installere de nødvendige Skolelinux pakkene for å få til et
3075 fullverdig system. Disse pakkene ble installert manuelt i første
3076 omgang, men ble senere installert automatisk via et script som Petter
3077 Reinholdtsen laget. Dette scriptet er så enkel å bruke at man er i
3078 gang med installasjonen i løpet av bare
5 minutter. Ikke nok med det,
3079 alt skjer helt automatisk. Alt i alt er jeg veldig fornøyd med
3080 resultatet av installasjonsprosessen. Raspberry Pi er en veldig svak
3081 maskin og det merkes godt når man har installert Skolelinux på
3082 den. Video og
3D-rendering fungerer utrolig dårlig, men nettsurfing og
3083 kontorprogrammer fungerer godt. Det kan derfor konkluderes med at
3084 datamaskinen er egnet for enkle oppgaver.
3086 <p
>Jeg syns det er viktig påpeke at dette kun er startfasen av en slik
3087 løsning. På markedet finnes det nå maskiner som har bedre hardware enn
3088 Raspberry Pi. Det er store muligheter for at man kan klare å
3089 installere Skolelinux på disse også, og da forsvinner nok mest
3090 sannsynlig ytelsesproblemene med Video og
3D rendering også.
</p
>
3092 <p
>Det ble også prøvd med en løsning som gjorde at Raspberry Pi
3093 fungerte som en tynnklient. Denne løsningen hadde langt bedre ytelse
3094 med tanke på hastighet og brukeropplevelse. Men også her var video og
3095 3D rendering dårlig. Det ble brukt en liten Linux distribusjon kalt
3096 <a href=
"http://www.berryterminal.com/
">BerryTerminal
</a
> for å få til
3099 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
3101 <p
>Fordelen med Skolelinux er mange. At det er gratis er en stor
3102 fordel, men at det er så mange som er med på å utvikle det og
3103 vedlikeholde det er en enda større fordel. Allerede før jeg startet
3104 med prosjektet så jeg mange fordeler, og når jeg nærmet meg sluttfasen
3105 så jeg langt flere. At prosjektet skulle inneha en så høy kvalitet
3106 hadde jeg aldri trodd. En vanlig Skolelinux installasjon har de
3107 nødvendige programmene og funksjonen som både små og store skoler i
3108 tillegg til organisasjoner kan klare seg med. At prosjektet tilbyr en
3109 så komplett løsning er en kjempefordel. Installasjonen er knirkefri
3110 og det er svært enkelt å installere og komme i gang.
</p
>
3112 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
3114 <p
>Ulempene jeg ser med prosjektet er ryddigheten av websidene. Selv
3115 om websidene er enkle og konsise er det allikevel ikke appellerende i
3116 like stor grad som for eksempel
3117 <a href=
"http://www.ubuntu.com
">Ubuntu
</a
> sine sider. Deres side
3118 tilbyr, i tillegg til godt design og presentasjon, en nettbasert
3119 emulator av deres operativsystem. Dette er en stor fordel slik jeg ser
3120 det. Bortsett fra dette ser jeg absolutt ingen ulemper med
3121 Skolelinux-prosjektet.
</p
>
3123 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
3125 <p
>Til daglig er jeg en flittig bruker av det åpne media
3126 sentersystemet
<a href=
"http://xbmc.org/
">XBMC
</a
>. Det enorme
3127 samfunnet rundt dette prosjektet har gjort dette til et program som
3128 dekker alles behov. Man kan tilpasse det akkurat slik man vil både med
3129 tanke på utseende og funksjoner ved installere plug-ins eller
3132 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
3133 skoler til å ta i bruk fri programvare?
</strong
></p
>
3135 <p
>Strategien som burde brukes sett fra mine øyne er
3136 markedsføring. Jeg er sikker på at om flere skoler fikk et lite innsyn
3137 i hvor bra Skolelinux er så ville de ikke nølt med å gå over fra noe
3138 annet som koster de store summer. At skolelinux til de grader tilbyr
3139 en så komplett løsning bure komme frem. Enten via reklamekampanjer
3140 eller ved å sende ut folk til skoler for så å la skolenettverk
3141 ansvarlige få teste ut hvordan Skolelinux fungerer i praksis. Om det
3142 i tillegg ble utviklet gode websider og en emulator for å la brukere
3143 prøve operativsystemet ville nok dette ha styrket inntrykket
3144 betraktelig.

3238 <p
>Debian Edu, also known as Skolelinux, is a Linux distribution based
3239 on Debian providing an out-of-the box environment of a completely
3240 configured school network. Immediatly after installation a school
3241 server running all services needed for a school network is set up just
3242 waiting for users and machines being added via GOsa², a comfortable
3243 Web-UI. A netbooting environment is prepared using PXE, so after
3244 initial installation of the main server from CD, DVD or USB stick all
3245 other machines can be installed via the network.

3330 var basert på et notat som besvarte spørsmål fra ordfører Tor Nysæter
3331 og rådgiver for skolesektoren, Petter Falkbu, om bruken av Skolelinux
3332 i Narvikskolene og konstnaden ved å gå over til Windows. For litt

3343 at læreplanens krav oppfylles uten problemer ved bruk av Skolelinux.

3345 unødige utgifter på IT i skoleverket. :)

</a

3399 out-of-the box environment of a completely configured school
3400 network. Immediatly after installation a school server running all
3401 services needed for a school network is set up just waiting for users
3402 and machines being added via GOsa², a comfortable Web-UI. A netbooting
3403 environment is prepared using PXE, so after initial installation of
3404 the main server from CD, DVD or USB stick all other machines can be
3405 installed via the network.

3531 the video show a walk-through of of the menu content, demonstration of
3532 a few programs and his view of our distribution.
</p
>
3534 <p
>There is also some really nice quotes (transcribed by me, might
3535 have heard wrong). While looking thought the Graphics menu:
</p
>
3538 "Basically everything you ever need in a school environment.
"
3541 <p
>And as a general evaluation of the entire distribution:
</p
>
3544 "So, yeah, a bit bloated. It kept all the Debian stuff in there, just
3545 to keep it nice and GNU. So, I do not want to go on about it, but
3546 lets give it
7 out of
10. I am not going to use it. That is because
3547 I am not deploying a school network. There may be some mythical
3548 feature to help you deploy Skolelinux on a school network.
"
3551 <p
>To bad he did not test the server profile, and discovered the PXE
3552 installation option. It make it possible to install only the main
3553 server from CD, and the rest of the machines via the net, and might be
3554 considered the mythical feature he talk about. :)
</p
>
3556 <p
>While looking through the menus, there is also this funny comment
3557 about the part of the K menu generated from the Debian menu subsystem:
3560 "[The K menu] have a special Debian section for software that no-one
3561 is going to look at, because it contain lots of junky stuff that you
3562 actually don
't need in the education distribution, but have just been
3563 included because it isn
't stripped out for some reason.
"
3566 <p
>I guess it is yet another argument for merging the Debian menu and
3567 Gnome/KDE desktop menu entries into
3568 <a href=
"http://wiki.debian.org/Proposals/DebianMenuUsingDesktopEntries
">one
3569 consistent menu system
</a
> instead of two incomplete and partly
3570 inconsistent menu systems.

>Etter en lang pause og travle uker har jeg endelig klart å få
3682 samlet et nytt intervju med en av folkene i
3683 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet.
3684 Denne gang er det Helge Tore Høyland, en mangeårig bidragsyter på
3685 epostlistene og ellers i prosjektet.
</p
>
3687 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
3689 <p
>Eg er IT-konsulent/teknikker hjå eit firma i Steinkjer med navn
3690 <a href=
"http://unoit.no/
">Uno IT
</a
>. Uno IT er eit lite firma som
3691 drifter nettverk og maskiner for små og mellomstore firma
3692 Steinkjer-området. Per dags dato er me
2 ansatte. Min faglege bakgrunn
3693 er Fagbrev som it-teknikker, samt nokre fag innen nettverk- og
3694 server-drift frå HiST og NTNU. Dagleg arbeid består i oppsett av nye
3695 maskiner og hjelp til sluttbrukere, samt oppsett og vedlikehold av eit
3696 vidt spekter av fagsystemer ute hjå kunder. Erfaring med Skolelinux
3697 har eg hatt i forbindelse med drifting av
3698 <a href=
"http://www.bjorkly.no/
">Bjørkly skule
</a
>, ein privat
3699 grunnskule i Namsos-området. I dag har skulen
65 elever,
15 lærere,
1
3700 hovedserver og ca
60 klienter som kjører halvtjukt. Eg har bygd og
3701 driftet systemet sidan summaren
2006.
</p
>
3703 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
3705 <p
>Eg kom i kontakt med Skolelinux-prosjektet via ein artikkel i eit
3706 fagblad, som eg ikkje lenger hugsar namnet på. I og med at eg allereie
3707 hadde pusla med nettverk for ein annan skule, fatta eg straks
3708 interesse for prosjektet.
</p
>
3710 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
3712 <p
>Fordelane med Skolelinux er sentralisert administrasjon og svært
3713 mange gode verktøy «ut av boksen». Veldig kjekt å kunne drifte
60
3714 klientar med berre å «bry» seg med ein server. Levetid for systemets
3715 hardware er og ein veldig fin effekt. I tillegg kjem fordelar som økt
3716 sikkerhet og mindre lisenskostnader. Etter min erfaring er det og
3717 mykje mindre driftskostnader med eit slikt system enn konkurrerande
3718 system, pga enkelhet med sentralisert administrasjon. På grunn av at
3719 Skolelinux er basert på Debian er det òg svært stabilt.
</p
>
3721 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
3723 <p
>Ulemper er mangel på vilje til å følge standarer ute i markedet,
3724 som fører til mangel på støtte til nokre mykje brukte ting. Flash og
3725 Java er typiske eksempel. Sidan Debian satsar på stabilitet framfor å
3726 ha nyeste pakke av eit program, kan ein i nokre tilfeller kome borti
3727 at program vert «for gamle». Det er spesielt nettlesaren som er
3728 utsett. Mangel på vilje til å utvikle pedagogisk programvare, i Noreg,
3729 for «alle» platformer fører òg til noko hovudbry.
</p
>
3731 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
3733 <p
>Til dagleg bruker eg svært mange forskjellige «fri programvare»
3734 program. Firefox, Thunderbird, Freecommander, ImgBurn, Clonezilla,
3735 OCS inventory, Icinga, Skolelinux, SystemRescueCD og mykje meir.
</p
>
3737 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
3738 skoler til å ta i bruk fri programvare?
</strong
></p
>
3740 <p
>Strategisk må ein fokusere på at sluttbruker eigentleg ikkje er så
3741 fokusert på at det er fri programvare men at det skal «berre fungere».
3742 Gjer det enkelt å bruker og ikkje minst å administrere. For Skolelinux
3743 sin del må ein få eit betre fokus på overganger. Utbytting av servere
3744 må gå meir automatisk, import og eksport av brukerbase og maskinbase
3745 med meir må kunne gå enkelt og oppgradering til neste versjon må bli
3746 mykje meir automatisk og gjennomtesta. Ein må unngå at ein må sette
3747 opp frå start når ein byter ut ein server eller oppgraderer til neste
3748 versjon. For å få Skolelinux til å bli eit betre alternativ for skular
3749 må ein ha fokus på nettlesaren. Denne må bli «up to date» og støtte
3750 dei protokollar og tillegg som vert brukt av forlag med meir. Etter
3751 kvart som meir og meir blir flytta ut i «skya» vert dette viktigare og
3752 viktigare. Ein kunne ynskje og jobbe for at forlag med fleire tar i
3753 bruk opne standarer, men inntil det skjer, må systemet kunne brukast
3754 mot desse fagsystema.
</p
>
3756 <p
>For meg har prosjektet med Skolelinux vore ein svært artig og
3757 lærerik prosess. Miljøet rundt er ikkje enormt stort, dog stort nok,
3758 men det er svært hjelpevillig og engasjert.

3772 present. As the Debian Edu / Skolelinux project is very short on
3773 funding these days, and thus lack the money to do regular developer
3774 gatherings, this donation was most welcome. One developer gathering
3775 cost around NOK
15&nbsp;
000,-, so we need quite a lot more to keep the
3776 development pace we want. Thus, I hope their example this year is
3777 followed by many others. :)

3795 interesting, as I am involved with several organizations where
3796 accounting is an issue, and I have not really become too friendly with
3797 the different web based systems we use. I find it hard to find what I
3798 look for in the menus and even harder try to get sensible data out of
3799 the systems. Ledger seem different. The accounting data is kept in
3800 text files that can be stored in a version control system, and there
3802 are at least
<a href=

3803 different implementations

3853 if you know about someone I should interview, Please send me an email.
3854 After asking for many months, I finally managed to lure another one of
3855 the people behind the German
3856 "<a href=

">IT-Zukunft Schule

3857 project out from maternity leave to conduct an interview. Give a warm
3858 welcome to Angela Fuß. :)
</p
>
3860 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
3862 <p
>I am a
39-year-old woman living in the very north of Germany near
3863 Denmark. I live in a patchwork family with
"my man
" Mike Gabriel, my
3864 two daughters, Mikes daughter and Mikes and my rather newborn son.
3866 <p
>At the moment - because of our little baby - I am spending most of
3867 the day by being a caring and organising mom for all the kids.
3868 Besides that I am really involved into and occupied with several inner
3869 growth processes: New born souls always bring the whole familiar
3870 system into movement and that needs time and focus ;-). We are also
3871 in the middle of buying a house and moving to it.
</p
>
3873 <p
>In
2013 I will work again in my job in a German foundation for
3874 nature conservation. I am doing public relation work there. Besides
3875 that - and that is the connection to Skolelinux / Debian Edu - I am
3876 working in our own school project
"IT-Zukunft Schule
" in North
3877 Germany. I am responsible for the quality assurance, the customer
3878 relationship management and the communication processes in the
3881 <p
>Since
2001 I constantly have been training myself in communication
3882 and leadership. Besides that I am a forester, a landscaping gardener
3883 and a yoga teacher.
</p
>
3885 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
3886 project?
</strong
></p
>
3888 <p
>I fell in love with Mike ;-).
</p
>
3890 <p
>Very soon after getting to know him I was completely enrolled into
3891 Free Software. At this time Mike did IT-services for one newly
3892 founded school in Kiel. Other schools in Kiel needed concepts for
3893 their IT environment. Often when Mike came home from working at the
3894 newly founded school I found myself listening to his complaints about
3895 several points where the communication with the schools head or the
3896 teachers did not work. So we were clear that he would not work for
3897 one more school if we did not set up a structure for communication
3898 between him, the schools head, the teachers, the students and the
3901 <p
>Together with our friend and hardware supplier Andreas Buchholz we
3902 started to get an overview of free software solutions suitable for
3903 schools. One day before Christmas
2010 Mike and I had a date with Kurt
3904 Gramlich in Gütersloh. As Kurt and I are really interested in building
3905 networks of people and in being in communication we dived into
3906 Skolelinux and brought it to the first grammar schools in Northern
3909 <p

</p
>
3913 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
3914 Edu?
</strong
></p
>
3916 <p
>First I have to say: I cannot answer this question technically. My
3917 answer comes rather from a social point of view.
</p
>
3919 <p
>The biggest advantage of Skolelinux / Debian Edu I see is the large
3920 and strong international community of Debian Developers in the
3921 background which is very alive and connected over mailinglists, blogs
3922 and meetings. My constant feeling for the Debian Community is: If
3923 something does not work they will somehow fix it. All is well
3924 ;-). This is of course a user experience. What I also get as a big
3925 advantage of Skolelinux / Debian Edu is that everybody who uses it and
3926 works with it can also contribute to it - that includes students,
3927 teachers, parents...
</p
>
3929 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
3930 Edu?
</strong
></p
>
3932 <p
>I will answer this question relating to the internal structure of
3933 Skolelinux / Debian Edu.
</p
>
3935 <p
>What I see as a major disadvantage is that there is a gap between
3936 the group of developers for Debian Edu and the people who make the
3937 marketing, that means the people that bring Skolelinux to the
3938 schools. There is a lack of communication between these two groups and
3939 I think that does not really work for Skolelinux / Debian Edu.
</p
>
3941 <p
>Further I appreciate that Skolelinux / Debian Edu is known as a
3942 do-ocracy. Nevertheless I keep asking myself if at some points a
3943 democracy or some kind of hierarchical project structure would be good
3944 and helpful. I am also missing some kind of contact between the
3945 Skolelinux / Debian Edu communities in Europe or on an international
3946 level. I think it would be good if there was more sharing between the
3947 different countries using Skolelinux / Debian Edu.
</p
>
3949 <p
><strong
>Which free software do you use daily?
</strong
></p
>
3951 <p
>On my laptop I am still using an Ubuntu
10.04 with a Gnome Desktop
3952 on. As applications I use Openoffice.org, Gedit, Firefox, Pidgin,
3953 LaTeX and GnuCash. For mails I am using Horde. And I am really fond of
3954 my N900 running with Maemo.
</p
>
3956 <p
><strong
>Which strategy do you believe is the right one to use to
3957 get schools to use free software?
</strong
></p
>
3959 <p
>I am really convinced that in our school project
"IT-Zukunft
3960 Schule
" we have developed (and keep developing) a great way to get
3961 schools to use Free Software. We have written a detailed concept for
3962 that so I cannot explain the whole thing here. But in a nutshell the
3963 strategy has three crucial pillars:
</p
>
3967 <li
>We really take time to get what sort of stories, questions and
3968 concerns the schools head and the teachers have about using different
3969 kinds of IT and we take time to enrol them into Free Software.
</li
>
3971 <li
>Our solution for schools is never just technical. In the centre
3972 are always the people who are going to use the software. From the very
3973 beginning of the planning for a school, we tell the schools head that
3974 they are paying us not only for a technical solution for their school,
3975 they also pay us for leading all the communication processes
3976 needed. If they do not want that, we are not working with them because
3977 we cannot give a guarantee for the quality of our work then.
</li
>
3979 <li
>Another focus lies in the training of teachers and students in
3980 co-administrating the IT-System at their school. They start getting in
3981 contact with the Skolelinux / Debian Edu community and they get the
3982 offer to become more and more independent from us.

4005 <p
>I sommer (
2012-
07-
23) hadde Fremover et oppslag om at Narvik
4006 kommune hadde spart mellom
10 og
20 millioner kroner de siste årene på
4007 å bruke Skolelinux på sine skoler. Harstad har også tatt i bruk
4008 Skolelinux på alle sine skoler. Som tidligere Ballangsværing gledet
4009 det meg stort å se at skoleløsningen vi har utviklet siden
2001 tas i
4010 bruk i området der jeg vokste opp, og dermed bidrar til en bedre og
4011 billigere skolehverdag.
</p
>
4013 <p
>Skolelinux er en komplett IT-løsning for elevnettverket på en
4014 skole, med både nettverkstjenester og løsning for elevmaskiner med
4015 pedagogisk programvare, som tillater en å øke levetiden på en
4016 datamaskin i skolen med mange år. En undersøkelse publisert i mars
4017 2012 viste at de
56 norske skolene som har offentliggjort at de bruker
4018 Skolelinux eller annen Linuxutgave hadde
36% større PC-tetthet enn
4019 landsgjennomsnittet, når en ser på tall rapportert til Grunnskolens
4020 Informasjonssystem. I følge Paul Reidar Løsnesløkken, IKT-konsulent i
4021 Nord-Odal, fungerer datamaskiner godt til de er
8 til
10 år gamle.
</p
>
4023 <p
>I høst (
2012-
09-
29) fortalte Fremover hvordan Ballangen kommune har
4024 opparbeidet seg
20 millioner i underskudd og nok havner på Robek-lista
4025 fra nyttår. Kanskje Ballangen også burde ta i bruk Skolelinux for å
4026 spare penger? Hvis kommunen mangler kompetanse lokalt på Linux finnes
4027 det kommersielle selskaper som tilbyr driftstjenester rundt
4028 Skolelinux, og jeg bør vel avsløre at jeg selv er involvert i et av
4029 dem, Skolelinux Drift AS. Kommunen kan dermed få hjelp hvis de ikke
4030 ønsker å bygge opp egen kompetanse.

4058 består av ca.
1,
3 millioner bokmåls- og nynorskord. Det er mange
4059 kilder til ordene, f.eks. den norske ordbanken, norske nett-aviser,
4060 stavekontrollbrukere og korrekturlesere, og endel feil har sneket seg
4061 inn i databasen over ord. For å finne og fikse feilene trengs det
4062 korrekturlesing. Her kommer frivillige inn.

>Hvis du vil bidra med korrektur av orddatabasen, kan du melde deg
4065 frivillig som bokmåls- eller nynorskkorrekturleser og få tilsendt en
4066 liten bunke ord på epost hver dag, lese over og sende inn på epost
4067 tilbake til korrekturlesing-systemet. Jo flere som sjekker, jo
4068 raskere kommer vi igjennom hele databasen. Så langt har vi oppdaget
4069 341 bokmålsord og
50 nynorskord som ikke skal vært med i databasen.
4070 Det er nok noen flere. I tillegg har korrekturleserne oppdaget flere
4071 ord som manglet, og fått lagt dem inn i stavekontrollen.

4101 noe utviklerne er veldig glade for.

4103 <p
>Den største endringen er at byggesystemet for stavekontrollen er
4104 skrevet om til å akseptere ord med bindestrek (f.eks. «e-post»). Litt
4105 over
10.000 slike ordformer er lagt til i orddatabasen. I tillegg er
4106 det kommet en del nye ord og rettelser rapportert inn av de frivillige
4107 som gjennomfører korrektur av orddatabasen i prosjektet. For å få
4108 fortgang i dette korrekturarbeidet er det fint med flere frivillige

>After a long break in my row of interviews with people in the
4198 <a href=
"http://www.skolelinux.org/
">Debian Edu and Skolelinux
</a
>
4199 community, I finally found time to wrap up another. This time it is
4200 Giorgio Pioda, which showed up on the mailing list at the start of
4201 this year, asking questions and inspiring us to improve the first time
4202 administrators experience with Skolelinux. :) The interview was
4203 conduced in May, but I only found time to publish it now.
</p
>
4205 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
4207 <p
>I have a PhD in chemistry but since several years I work as teacher
4208 in secondary (
15-
18 year old students) and tertiary (a kind of
"light
"
4209 university) schools. Five years ago I started to manage a Learning
4210 Management Service server and slowly I got more and more involved with
4211 IT.
3 years ago the graduating schools moved completely to Linux and I
4212 got the head of the IT for this. The experience collected in chemistry
4213 labs computers (for example NMR analysis of protein folding) and in
4214 the IT-courses during university where sufficient to start. Self
4215 training is anyway very important
</p
>
4217 <p
>I live in the Italian speaking part of Switzerland, and the
4218 <a href=
"http://www.spse.ch/
">SPSE school
</a
> (secondary) is a very
4219 special sport school for young people who try to became sport pro (for
4220 all sports, we have dozens of disciplines represented) and we are
4221 recognised by the Olympic Swiss Organisation.
4223 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4224 project?
</strong
></p
>
4226 <p
>Looking for Linux / Primary Domain Controller (PDC) I found it
4227 already several years ago. But since the system was still not
4228 Kerberized and since our schools relies strongly on laptops I didn
't
4229 use it. I plan to introduce it in the next future, probably for the
4230 next school year, since the squeeze release solved this security
4233 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4234 Edu?
</strong
></p
>
4236 <p
>Many. First of all there is a strong and living community that is
4237 very generous for help and hints. Chat help is crucial, together with
4238 the mailing list. Second. With Skolelinux you get an already well
4239 engineered platform and you don
't have to start to build up your PDC
4240 and your clients from GNU/scratch; I
've already done this once and I
4241 can tell it, it is hard. Third, since Skolelinux is a standard
4242 platform, it is way easier to educate other IT people and even if the
4243 head IT is sick another one could pick up the task without too much
4246 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
4247 Edu?
</strong
></p
>
4249 <p
>The only real problem I see is that it is a little too less
4250 flexible at client level. Debian stable is rocky and desirable, but
4251 there are many reasons that force for another choice. For example the
4252 need of new drivers for new PC, or the need for a specific OS for some
4253 devices that have specific software packages for another specific
4254 distribution (I have such a case for whiteboards that have only
4255 Ubuntu packages). Thus, I prepared compatibility packages educlient
4256 and eduroaming, hoping not to use them ;-)
</p
>
4258 <p
><strong
>Which free software do you use daily?
</strong
></p
>
4260 <p
>I have a Debian Stable PDC at school (Kerberos, NIS, NFS) with
4261 mixed Debian and Ubuntu clients. If you think that this triad
4262 combination is exotic... well I discovered right yesterday that
4263 <a href=
"http://moo.nac.uci.edu/~hjm/Perceus-Report.html
">Perceus
</a
>
4264 has the same...
</p
>
4266 <p
>For myself I run Debian wheezy/sid, but this combination is good
4267 only I you have enough competence to fix stuff for yourself, if
4268 something breaks. Daily I use texmacs, gnumeric, a little bit of R
4269 statistics, kmplot, and less frequently OpenOffice.org.
</p
>
4271 <p
><strong
>Which strategy do you believe is the right one to use to
4272 get schools to use free software?
</strong
></p
>
4274 <P
>I think that the only real argument that school managers
"hear
" is
4275 cost reduction. They don
't give too much weight on quality, stability,
4276 just because they are normally not open to change.
</p
>
4278 <p
>Students adapts very quickly to GNU/Linux (and for them being able
4279 to switch between different OS is a plus value); teachers and managers
4280 don
't.
</p
>
4282 <p
>We decided to move to Linux because students at our school have own
4283 laptop and we have the responsibility to keep the laptop ready to use;
4284 we were really unsatisfied with Microsoft since every Monday we had
20
4285 machine to fix for viral infections... With Linux this has been
4286 reduced to zero, since people installs almost only from official
4287 repositories. I think that our special needs brought us to Linux.
4288 Those who don
't have such needs will hardly move to Linux.

4 og

4302 henvendelser til avisen for å få artikkelen på nett har så langt ikke
4303 vært vellykket.
</p
>
4305 <p
>Artikkelen med tittelen
"Narvik kommune bruker gratisprogram i
4306 skolen - Har spart millioner
", forteller om hvordan bruken av
4307 Skolelinux er en stor suksess i Narvik siden det ble tatt i bruk i
4308 2004. Her er noen fine sitater:
</p
>
4311 "- Skolelinux har spart kommunen for store pengesummer, millionbeløp,
4312 som de heller kan bruke på andre ting, sier IKT-konsulent Viggo
4316 <p
>Avisen forteller at de har fått tilgang til beregninger som viser
4317 at Narvik kommune har spart noe mellom
10 og
20 millioner kroner de
4318 siste
8 årene på å bruke Skolelinux, og fortsetter:
</p
>
4322 "Regnestykket tar høyde for sparte kostnader til lisenser som medfølger
4323 de alternative operativsystemene, lavere driftskostnader og lengre
4324 levetid på datautstyret. Totalt har Narvikskolen en maskinpark på
4325 1600 maskiner fordelt på de
11 skolene fra Skjomen i sør til Bjerkvik
4330 <p
>Viggo Fedreheim sier dette om hvor noe av gevinsten kommer fra:
</p
>
4333 "- Vi kan gjenbruke gamle maskiner i skolen som er for dårlig andre
4334 steder i kommunen der de ikke bruker Skolelinux. Levetiden på en
4335 datamaskin blir
3-
5 år lenger med Skolelinux. Vi kaller det for
4336 grønn IT, miljøvennlig IT.
"
4339 <p
>Her er det mulighet for flere kommuner å få et godt IT-system på
4340 skolene, hvis de er villige til å forsøke. De som ikke har kompetanse
4341 innomhus kan kjøpe det fra en av de kommersielle leverandørene av

4428 I have followed the Skolelinux project for quite some time by
4429 now. Earlier I tested out the K12-LTSP project, which we used for some
4430 time, but I really like the idea of having a distribution aimed to be
4431 a complete solution for schools with necessary tools integrated. When
4432 K12-LTSP abandoned that idea some years ago, I started to look more
4433 seriously into Skolelinux instead.

4436 Edu?
</strong

4438 The big point of Skolelinux to me is that it is a complete
4439 distribution, ready to install. It has LDAP-support, MS Windows
4440 integration tools and so forth already configured, saving an
4441 administrator a lot of time and headache. We were using another Linux
4442 based thin-client system called Thinlinc, that has served us very
4443 well. But that Skolelinux is based on VNC and LTSP, to me, is better
4444 when it comes to the kind of multimedia used in schools. That is
4445 showing videos from Youtube or educational TV. It is also easier to
4446 mix thin clients with workstations, since the user settings will be the
4447 same. In our VNC-based solution you had to
"beat around the bush
" by
4448 setting up a second, hidden, home-directory for user settings for the
4449 workstations, because they will be different from the ones used on the
4450 thin clients. Skolelinux support for diskless workstations are very
4451 convenient since a school today often need to use a class room
4452 projector showing videos in full screen. That is easily done with a
4453 small integrated media computer running as a diskless workstation. You
4454 have only two installs to update and configure. One for the thin
4455 clients and one for the workstations. Also saving a lot of time. Our
4456 old system was also based on Redhat and CentOS. They are both very
4457 nice distributions, but they are sometimes painfully slow when it
4458 comes to updating multimedia support and multimedia programs (even
4459 such as Gimp), leaving us with a bit
"oldish
" applications. Debian is
4462 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
4463 Edu?
</strong
></p
>
4465 <p
>Debian is a bit too quick when it comes to updating. As an example
4466 we use old HP terminals as thinclients, and two times already this
4467 year (
2012) the updates you get from the repositories has stopped
4468 sound from working with them. It
's a kernel/ALSA issue. So you have
4469 to be more careful properly testing the updates before you run them in
4470 a production environment. This has never happened with CentOS.
</p
>
4472 <p
>I also would like to be able to set my own domain-settings at
4473 install time. In Skolelinux they are kind of hard coded into the
4474 distribution, when it comes to LDAP and at least samba integration.
4475 That is more a cosmetic/translation issue, and not a real problem.
4476 Running MS Windows applications within the Skolelinux environment needs
4477 to be better supported. That is, running them seamlessly via RDP, and
4478 support for single-sign on. That will make the transition to free
4479 software easier, because you can keep the applications you really
4480 need. No support will make it impossible if you work in a school where
4481 some applications can
't be open source. As for us we really need to
4482 run Adobe InDesign in our journalist classes. We run a journalist
4483 education, and is one of the very few non university ones that is ok:d
4484 by Svenska journalistförbundet (Swedish journalist association). Our
4485 education gives the pupils the right of membership there, once they
4486 are done. This is important if you want to get a job.
</p
>
4488 <p
>Adobe InDesign is the program most commonly used in newspapers and
4489 magazines. We used Quark Express before, but they seem to loose there
4490 market to Adobe. The only
"equivalent
" to InDesign in the opensource
4491 world is Scribus, and its not advanced enough. At least not according
4492 to the teacher. I think it would be possible to use it, because they
4493 are not supposed to learn a program, they are supposed to learn how to
4494 edit and compile a newspaper. But politically at our school we are not
4495 there yet. And Scribus lacks a lot of things you find i InDesign.
</p
>
4497 <p
>We used even a windows program for sound editing when it comes to
4498 the radio-journalist part. The year to come we are going to try
4499 Audacity. That software has the same kind of limitations compared to
4500 Adobe Audition, but that teacher is a bit more open minded. We have
4501 tried Ardour also, but that instead is more like a music studio
4502 program, not intended for the kind of editing taking place in a radio
4503 studio. Its way to complex and the GUI is to scattered when you only
4504 want to cut, make pass-overs, add extra channels and normalise. Those
4505 things you can do in Audacity, but its not as easy as in Audition. You
4506 have to do more things manually with envelopes, and that is a bit old
4507 fashion and timewasting. Its also harder to cut and move sound from
4508 one channel to another, which is a thing that you do frequently
4509 because you often find yourself needing to rearrange parts of the
4510 sound file.
</p
>
4512 <p
>So, I am not sure we will succeed in replacing even Audition, but we
4513 will try. The problem is the students have certain expectations when
4514 they start an education towards a profession. So the programs has to
4515 look and feel professional. Good thing with radio, there are many
4516 programs out there, that radio studios use, so its not as standardised
4517 as Newspaper editing. That means, it does not really matter what
4518 program they learn, because once they start working they still have to
4519 learn the program the studio uses, so instead focus has to be to learn
4520 the editing part without to much focus on a specific software.

4524 <p

4525 only open source software, and preferably Linux based. When it comes
4526 to most used applications its OpenOffice, and Firefox (of course ;)
4529 <p
><strong
>Which strategy do you believe is the right one to use to
4530 get schools to use free software?
</strong
></p
>
4532 <p
>To get schools to use free software there has to be good open
4533 source software that are windows based, to ease the transition. But
4534 it
's also very important that the multimedia support is working
4535 flawlessly. The problems with Youtube, Twitter, Facebook and whatever
4536 will create problems when it comes to both teachers and
4537 students. Economy are also important for schools, so using thin
4538 clients, as long as they have good multimedia support, is a very good
4539 idea. It
's also important that the open source software works even for
4540 the administration. It
's hard to convince the teachers to stick with
4541 open source, if the principal has to run Windows. It also creates a
4542 problem if some classes has to use Windows for there tasks, since that
4543 will create a difference in
"status
" between classes, so a good
4544 support for running windows applications via the thin client (Linux)
4545 desktop is essential. At least at our school, where we have mixed
4546 level of educations, from high-school to journalist-school.

4793 Linux i en bokhandel i New York og ble veldig fascinert. Etter
4794 hjemkomsten begynte jeg å jobbe på Ulsrud VGS, som naturfagslærer, men
4795 som IT-interessert ble jeg fort en del av den nye IT-satsningen som
4796 skulle løfte Ulsrud og gi skolen en bedre rykte. Vi hadde ganske
4797 mange maskiner, som gikk på Win98 og to servere som ble oppgradert til
4798 Win2000. Systemene var ustabil og dårlige. På leting etter noe
4799 bedre, uten å knekke ryggen økonomisk, kom jeg over
"Linux i Skolen
"
4800 og Skolelinux. Jeg tok kontakt med miljøet og en gjeng møtte opp på
4801 skolen, der vi gjorde en liten testinstallasjon. Etter et par år var
4802 ryggraden på skolen Linux (Skolelinux) og vi hadde flere hundre
4803 maskiner, både tynne klienter (gamle og nye), bærbare (Debian) og noen
4804 stasjonære (Win2000). På et tidspunkt var Ulsrud den råeste IT-skolen

4811 økonomiske. Det faktum at vi slapp å kjøpe masse nye lisenser og at
4812 vi kunne bruke gammel hardware. Alt i alt gjorde dette at vi sparte
4813 mye, men i stede for å bruke mindre på IT brukte vi det vi sparte på å
4814 skaffe mer hardware og på den måten gi det beste tilbudet i landet til
4815 våre elever. For oss som driftet var det himmel å ha et system som
4816 gikk å administrere sentralt og effektivt. Det var heller ikke så
4817 dumt at vi kunne
"låse
" maskinene mer effektivt enn vi kunne med
4818 Microsoft Windows, slik at vi slapp mye feil og problemer som ble
4819 forårsaket av
"kreative

4845 seg inn på hvor mye man sparer. Det betyr selvsagt at man sparer på
4846 lisenser, men også på driftsinnsats. Men nå når jeg ikke er en aktiv
4847 del av miljøet lenger hører jeg nesten ingen ting om fri programvare.
4848 Jeg stiller meg da spørsmålet om det har blitt stille rundt miljøet,
4849 eller om jeg kun så det tydeligere før når jeg var aktiv? Uansett er
4850 det for stille rundt Skolelinux-prosjektet nå.

4860 another interview with the people behind

">Debian Edu and Skolelinux
</a
>.
4862 This time we get to know José Luis Redrejo Rodríguez, one of our great
4863 helpers from Spain. His effort was the reason we added support for
4864 several desktop types (KDE, Gnome and most recently LXDE) in Debian
4865 Edu, and have all of these available in the recently published

><strong
>How did you get in contact with the Skolelinux/Debian Edu
4876 project?
</strong
></p
>
4878 <p
>At
2006, I verified that both, we in Extremadura and Skolelinux
4879 project, had been working in parallel for some years, doing very
4880 similar things, using very similar tools and with similar targets, so
4881 I decided it was time to join forces as much as possible.

4883 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4884 Edu?
</strong
></p
>
4886 <p
>A community of highly skilled experts working together, with a
4887 really open schema of collaboration and work. I really love the
4888 concepts of Do-ocracy and Merit-ocracy and the way these concepts are
4889 been used everyday inside Debian Edu.
</p

4891 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
4892 Edu?
</strong
></p
>
4894 <p
>Sometimes the differences in the implementations, laws or
4895 economical and technical resources in the different countries don
't
4896 allow us to agree in the same solution for all of us, and several
4897 approaches are needed, what is a waste of effort. Also, there is a
4898 lack of more man power to be able to follow the fast evolution of the
4899 technologies in school.
</p

4901 <p

4903 <p

</p

4907 <p
><strong
>Which strategy do you believe is the right one to use to
4908 get schools to use free software?
</strong
></p
>
4910 <p
>I think there is not a single strategy because there are very
4911 different scenarios: schools with mixed proprietary and free
4912 environments, schools using only workstations, other schools using
4913 laptops, netbooks, tablets, interactive white-boards, etc.
</p
>
4915 <p
>Also the range of ages of the students is very broad and you can
4916 not use the same solutions for primary schools and secondary or even
4917 universities. So different strategies are needed.
</p
>
4919 <p
>But, looking at these differences, and looking back to the things
4920 we
've done and implemented, and the places were we have spent most of
4921 our forces, I think we should focus as much as possible in free
4922 multi-platform environments, using only standards tools, and moving
4923 more and more to Internet or network solutions that could be deployed
4924 using wireless. I think we
'll see more and more personal devices in
4925 the schools, devices the students and teachers will take home with
4926 them, so the solutions must be able to be taken at home and continue
4927 working there.

>During my work on
4937 <a href=
"http://www.debian.org/News/
2012/
20120311.nb.html
">Debian Edu
4938 based on Squeeze
</a
>, I came across some issues that should be
4939 addressed in the Wheezy release. I finally found time to wrap up my
4940 notes and provide quick summary of what I found, with a bit
4941 explanation.
</p
>
4945 <li
>We need to rewrite our package installation framework, as tasksel
4946 changed from using tasksel tasks to using meta packages (aka packages
4947 with dependencies like our education-* packages), and our installation
4948 system depend on tasksel tasks in
4949 /usr/share/tasksel/debian-edu-tasks.desc for package
4950 installation.
</li
>
4952 <li
>Enable Kerberos login for more services. Now with the Kerberos
4953 foundation in place, we should use it to get single sign on with more
4954 services, and avoiding unneeded password / login questions. We should
4955 at least try to enable it for these services:
4958 <li
>CUPS for admins to add/configure printers and users when using
4960 <li
>Nagios for admins checking the system status.
</li
>
4961 <li
>GOsa for admins updating LDAP and users changing their passwords.
</li
>
4962 <li
>LDAP for admins updating LDAP.
</li
>
4963 <li
>Squid for users when exam mode / filtering is active.
</li
>
4964 <li
>ssh for admins and users to save a password prompt.
</li
>
4966 </ul
></li
>
4968 <li
>When we move GOsa to use Kerberos instead of LDAP bind to
4969 authenticate users, we should try to block or at least limit access to
4970 use LDAP bind for authentication, to ensure Kerberos is used when it
4971 is intended, and nothing fall back to using the less safe LDAP bind
</li
>
4973 <li
>Merge debian-edu-config and debian-edu-install. The split made
4974 sense when d-e-install did a lot more, but these days it is just an
4975 inconvenience when we update the debconf preseeding values.
</li
>
4977 <li
>Fix partman-auto to allow us to abort the installation before
4978 touching the disk if the disk is too small. This is
4979 <a href=
"http://bugs.debian.org/
653305">BTS report #
653305</a
> and the
4980 d-i developers are fine with the patch and someone just need to apply
4981 it and upload. After this is done we need to adjust
4982 debian-edu-install to use this new hook.
</li
>
4984 <li
>Adjust to new LTSP framework (boot time config instead of install
4985 time config). LTSP changed its design, and our hooks to install
4986 packages and update the configuration is most likely not going to work
4989 <li
>Consider switching to NBD instead of NFS for LTSP root, to allow
4990 the Kernel to cache files in its normal file cache, possibly speeding
4991 up KDE login on slow networks.
</li
>
4993 <li
>Make it possible to create expired user passwords that need to
4994 change on first login. This is useful when handing out password on
4995 paper, to make sure only the user know the password. This require
4996 fixes to the PAM handling of kdm and gdm.
</li
>
4998 <li
>Make GUI for adding new machines automatically from sitesummary.
4999 The current command line script is not very friendly to people most
5000 familiar with GUIs. This should probably be integrated into GOsa to
5001 have it available where the admin will be looking for it..
</li
>
5003 <li
>We should find way for Nagios to check that the DHCP service
5004 actually is working (as in handling out IP addresses). None of the
5005 Nagios checks I have found so far have been working for me.
</li
>
5007 <li
>We should switch from libpam-nss-ldapd to sssd for all profiles
5008 using LDAP, and not only on for roaming workstations, to have less
5009 packages to configure and consistent setup across all profiles.
</li
>
5011 <li
>We should configure Kerberos to update LDAP and Samba password
5012 when changing password using the Kerberos protocol. The hook was
5013 requested in
<a href=
"http://bugs.debian.org/
588968">BTS report
5014 #
588968</a
> and is now available in Wheezy. We might need to write a
5015 MIT Kerberos plugin in C to get this.
</li
>
5017 <li
>We should clean up the set of applications installed by default.
5020 <li
>reduce the number of chemistry visualisers
</li
>
5021 <li
>consider dropping xpaint
</li
>
5022 <li
>and probably more?
</li
>
5023 </ul
></li
>
5025 <li
>Some hardware need external firmware to work properly. This is
5026 mostly the case for WiFi network cards, but there are some other
5027 examples too. For popular laptops to work out of the box, such
5028 firmware need to be installed from non-free, and we should provide
5029 some GUI to do this. Ubuntu already have this implemented, and we
5030 could consider using their packages. At the moment we have some
5031 command line script to do this (one for the running system, another
5032 for the LTSP chroot).
</li
>
5035 <li
>In Squeeze, we provide KDE, Gnome and LXDE as desktop options. We
5036 should extend the list to Xfce and Sugar, and preferably find a way to
5037 install several and allow the admin or the user to select which one to
5040 <li
>The golearn tool from the goplay package make it easy to check out
5041 interesting educational packages. We should work on the package
5042 tagging in Debian to ensure it represent all the useful educational
5043 packages, and extend the tool to allow it to use packagekit to install
5044 new applications with a simple mouse click.
</li
>
5046 <li
>The Squeeze version got half a exam solution already in place,
5047 with the introduction of iptable based network blocking, but for it to
5048 be a complete exam solution the Squid proxy need to enable
5049 filtering/blocking as well when the exam mode is enabled. We should
5050 implement a way to easily enable this for the schools that want it,
5051 instead of the
"it is documented
" method of today.
</li
>
5053 <li
>A feature used in several schools is the ability for a teacher to
5054 "take over
" the desktop of individual or all computers in the room.
5055 There are at least three implementations,
5056 <a href=
"italc.sourceforge.net/
">italc
</a
>,
5057 <a href=
"http://www.itais.net/help/en/
">controlaula
</a
> og
5058 <a href=
"http://www.epoptes.org/
">epoptes
</a
> and we should pick one of
5059 them and make it trivial to set it up in a school. The challenges is
5060 how to distribute crypto keys and how to group computers in one room
5061 and how to set up which machine/user can control the machines in a
5062 given room.
</li
>
5064 <li
>Tablets and surf boards are getting more and more popular, and we
5065 should look into providing a good solution for integrating these into
5066 the Debian Edu network. Not quite sure how. Perhaps we should
5067 provide a installation profile with better touch screen support for
5068 them, or add some sync services to allow them to exchange
5069 configuration and data with the central server. This should be
5070 investigated.

2010, Mike Gabriel showed up on the
5085 <a href=

</p

5091 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
5093 <p
>My name is Mike Gabriel, I am
38 years old and live near Kiel,
5094 Schleswig-Holstein, Germany. I live together with a wonderful partner
5095 (Angela Fuß) and two own children and two bonus children (contributed
5096 by Angela).
</p
>
5098 <p
>During the day I am part-time employed as a system administrator
5099 and part-time working as an IT consultant. The consultancy work
5100 touches free software topics wherever and whenever possible. During
5101 the nights I am a free software developer. In the gaps I also train in
5102 becoming an osteopath.
</p
>
5104 <p
>Starting in
2010 we (Andreas Buchholz, Angela Fuß, Mike Gabriel)
5105 have set up a free software project in the area of Kiel that aims at
5106 introducing free software into schools. The project
's name is
5107 "IT-Zukunft Schule
" (IT future for schools). The project links IT
5108 skills with communication skills.
</p
>
5110 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5111 project?
</strong
></p
>
5113 <p
>While preparing our own customised Linux distribution for
5114 "IT-Zukunft Schule
" we were repeatedly asked if we really wanted to
5115 reinvent the wheel. What schools really need is already available,
5116 people said. From this impulse we started evaluating other Linux
5117 distributions that target being used for school networks.
</p
>
5119 <p
>At the end we short-listed two approaches and compared them: a
5120 commercial Linux distribution developed by a company in Bremen,
5121 Germany, and Skolelinux / Debian Edu. Between
12/
2010 and
03/
2011 we
5122 went to several events and met people being responsible for marketing
5123 and development of either of the distributions. Skolelinux / Debian
5124 Edu was by far much more convincing compared to the other product that
5125 got short-listed beforehand--across the full spectrum. What was most
5126 attractive for me personally: the perspective of collaboration within
5127 the developmental branch of the Debian Edu project itself.
</p
>
5129 <p
>In parallel with this, we talked to many local and not-so-local
5130 people. People teaching at schools, headmasters, politicians, data
5131 protection experts, other IT professionals.
</p
>
5133 <p
>We came to two conclusions:
</p
>
5135 <p
>First, a technical conclusion: What schools need is available in
5136 bits and pieces here and there, and none of the solutions really fit
5137 by
100%. Any school we have seen has a very individual IT setup
5138 whereas most of each school
's requirements could mapped by a standard
5139 IT solution. The requirement to this IT solution is flexibility and
5140 customisability, so that individual adaptations here and there are
5141 possible. In terms of re-distributing and rolling out such a
5142 standardised IT system for schools (a system that is still to some
5143 degree customisable) there is still a lot of work to do here
5144 locally. Debian Edu / Skolelinux has been our choice as the starting
5147 <p
>Second, a holistic conclusion: What schools need does not exist at
5148 all (or we missed it so far). There are several technical solutions
5149 for handling IT at schools that tend to make a good impression. What
5150 has been missing completely here in Germany, though, is the enrolment
5151 of people into using IT and teaching with IT.
"IT-Zukunft Schule
"
5152 tries to provide an approach for this.
</p
>
5154 <p
>Only some schools have some sort of a media concept which explains,
5155 defines and gives guidance on how to use IT in class. Most schools in
5156 Northern Germany do not have an IT service provider, the school
's IT
5157 equipment is managed by one or (if the school is lucky) two (admin)
5158 teachers, most of the workload these admin teachers get done in there
5159 spare time.
</p
>
5161 <p
>We were surprised that only a very few admin teachers were
5162 networked with colleagues from other schools. Basically, every school
5163 here around has its individual approach of providing IT equipment to
5164 teachers and students and the exchange of ideas has been quasi
5165 non-existent until
2010/
2011.
</p
>
5167 <p
>Quite some (non-admin) teachers try to avoid using IT technology in
5168 class as a learning medium completely. Several reasons for this
5169 avoidance do exist.
</p
>
5171 <p
>We discovered that no-one has ever taken a closer look at this
5172 social part of IT management in schools, so far. On our quest journey
5173 for a technical IT solution for schools, we discussed this issue with
5174 several teachers, headmasters, politicians, other IT professionals and
5175 they all confirmed: a holistic approach of considering IT management
5176 at schools, an approach that includes the people in place, will be new
5177 and probably a gain for all.
</p
>
5179 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5180 Edu?
</strong
></p
>
5182 <p
>There is a list of advantages: international context, openness to
5183 any kind of contributions, do-ocracy policy, the closeness to Debian,
5184 the different installation scenarios possible (from stand-alone
5185 workstation to complex multi-server sites), the transparency within
5186 project communication, honest communication within the group of
5187 developers, etc.

5190 Edu?
</strong

5192 <p
>Every coin has two sides:
</p
>
5194 <p
>Technically:
<a href=
"http://bugs.debian.org/
311188">BTS issue
5195 #
311188</a
>, tricky upgradability of a Debian Edu main server, network
5196 client installations on top of a plain vanilla Debian installation
5197 should become possible sometime in the near future, one could think
5198 about splitting the very complex package debian-edu-config into
5199 several portions (to make it easier for new developers to
5200 contribute).
</p
>
5202 <p
>Another issue I see is that we (as Debian Edu developers) should
5203 find out more about the network of people who do the marketing for
5204 Debian Edu / Skolelinux. There is a very active group in Germany
5205 promoting Skolelinux on the bigger Linux Days within Germany. Are
5206 there other groups like that in other countries? How can we bring
5207 these marketing people together (marketing group A with group B and
5208 all of them with the group of Debian Edu developers)? During the last
5209 meeting of the German Skolelinux group, I got the impression of people
5210 there being rather disconnected from the development department of
5211 Debian Edu / Skolelinux.

5215 <p

</p

5217 <p
>For normal stuff I use Iceweasel/Firefox, Libreoffice.org. For
5218 serious text writing I prefer LaTeX. I use gimp, inkscape, scribus for
5219 more artistic tasks. I run virtual machines in KVM and Virtualbox.

5223 PyHoca-GUI has brought forth a Python X2Go Client API that currently
5224 is being integrated in Ubuntu
's software center.
</p

5226 <p
>For communications I have my own Kolab server running using Horde
5227 as web-based groupware client. For IRC I love to use irssi, for Jabber

5270 project?
</strong

5272 <p
>We had tried different Linux based school servers, when members of
5273 my local Linux User Group (LUG OWL) detected Skolelinux. I remember
5274 very well, being part of a party celebrating the Linux New Media Award
5275 (
"Best Newcomer Distribution
", also nominated: Ubuntu) that was given
5276 to Skolelinux at Linux World Exposition in Frankfurt,
2005 (IIRC). Few
5277 months later, I had the chance to join a developer meeting in Ulsrud
5278 (Oslo) and to hand out the award to Knut Yrvin and others. For more
5279 than
7 years, Skolelinux is part of our schools infrastructure, namely
5280 our main server (tjener), one LTSP (today without thin clients), and
5281 approximately
50 work stations. Most of these have the option to boot a
5282 locally installed Skolelinux image. As a consequence, I joined quite
5283 a few events dealing with free software or Linux, and met many Debian
5284 (Edu) developers. All of them seemed quite nice and competent to me,
5285 one more reason to stick to Skolelinux.

5290 <p
>Debian driven, you are given all the advantages of a community
5291 project including well maintained updates. Once, you are familiar with
5292 the network layout, you can easily roll out an entire educational
5293 computer infrastructure, from just one installation media. As only
5294 free software (FOSS) is used, that supports even elderly hardware,
5295 up-sizing your IT equipment is only limited by space (i.e. available
5296 labs). Especially if you run a LTSP thin client server, your
5297 administration costs tend towards zero.

>What do you see as the disadvantages of Skolelinux/Debian
5300 Edu?
</strong
></p
>
5302 <p
>While Debian
's stability has loads of advantages for servers, this
5303 might be different in some cases for clients: Schools with unlimited
5304 budget might buy new hardware with components that are not yet
5305 supported by Debian stable, or wish to use more recent versions of
5306 office packages or desktop environments. These schools have the
5307 option to run Debian testing or other distributions - if they have the
5308 capacity to do so. Another issue is that Debian release cycles
5309 include a wide range of changes; therefor a high percentage of human
5310 power seems to be absorbed by just keeping the features of Skolelinux
5311 within the new setting of the version to come. During this process,
5312 the cogs of Debian Edu are getting more and more professional,
5313 i.e. harder to understand for novices.

5315 <p

5326 <li
>Support computer science as regular subject in schools to make
5327 people really
"own
" their hardware, to make them understand the
5328 difference between proprietary software products, and free software
5329 developing.
</li
>
5331 <li
>Make budget baskets corresponding: In Germany
's public schools
5332 there are more or less fixed budgets for IT equipment (including
5333 licenses), so schools won
't benefit from any savings here. This
5334 privilege is left to private schools which have consequently a large
5335 share among German Skolelinux schools.
</li
>
5337 <li
>Get free software in the seminars where would-be teachers are
5338 trained. In many cases, teachers
' software customs are respected by
5339 decision makers rather than the expertise of any IT experts.
</li
>
5341 <li
>Don
't limit ourself to free software run natively. Everybody uses
5342 free software or free licenses (for instance Wikipedia), and this
5343 general concept should get expanded to free educational content to be
5344 shared world wide (school books e.g.).
</li
>
5346 <li
>Make clear where ever you can that the market share of free (libre)
5347 office suites is much above
20 p.c. today, and that you pupils don
't
5348 need to know the
"ribbon menu
" in order to get employed.
</li
>
5350 <li
>Talk about the difference between freeware and free software.
</li
>
5352 <li
>Spread free software, or even collections of portable free apps
5353 for USB pen drives. Endorse students to get a legal copy of
5354 Libreoffice rather than accepting them to use illegal serials. And
5355 keep sending documents in ODF formats.

5374 gledelig overrasket da han dukket opp i Skolelinux-prosjektet etter å
5375 ikke ha sett noe til ham på mange år.

5379 <p
>Jeg er utdannet kokk av yrke, og har utøvet yrket i
12 år. Men
5380 etter at ryggen sa takk før seg, studerte jeg nettverksadministrasjon
5381 ved Næringsakademiet i Bergen årene
2008-
2009 slik at jeg kunne
5382 forfølge en av mine største interesser - data. Til daglig jobber jeg
5383 ved
<a href=

5384 ungdomsskole
</a
> med å drifte skolens PC-er. Har også litt
5385 musikkundervisning.
</p
>
5387 <p
>Mitt mål er å bevisstgjøre musikklærene mulighetene med de frie
5388 programmene som finnes i Skolelinux, blant annet Rosegarden.
</p
>
5390 <p
>Har i mange år drevet med musikk og en av grunnen til at Rosegarden
5391 falt i smak for min del, var fordi denne fungere og ligner mest på
5392 Windows-programmet (cubase) jeg jobbet mye med da jeg i mine yngre
5393 dager var «Windows fanatiker». Ble introdusert til Linux av en kompis
5394 av meg for omtrent
14 år siden, og har bare blitt mer og mer glad i
5395 dette operativsystemet.

5397 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p

5399 <p
>Da jeg ble sykemeldt fra min gamle jobb, og måtte omskoleres,
5400 havnet jeg i
2007 sammen med Viggo Fedreheim på IKT-avdelingen i
5401 Narvik kommune, der ble jeg for første gang introdusert til
5402 Skolelinuxprosjektet.
</p
>
5404 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
5406 <p
>Skolelinux er enkelt å holde i drift og masse flotte programmer som
5407 geogebra, ktouch og kgeografi følger med pakken. Man kan ta i bruk
5408 gamle PC-er igjen, slik at skoler med dårlig råd får opp en brukbar
5409 PC-park. PC-er som er ca
6-
9 år gamle fungere tilfredstillende, bare
5410 de har
512 MB RAM eller mer.
</p
>
5412 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
5414 <p
>Ulempene er at noen av de pedagogiske programmene som lærene ønsker
5415 å bruke fungere dårlig med Linux. Mye pga. av at disse programmene
5416 blir ikke laget til Linuxbaserte operativsystemer.
</p
>
5418 <p
>Video- og bilde-redigering har dessverre en del mangler, mange av
5419 programmene har en tendens til og krasje. Det gjelder blant annet
5420 <a href=
"http://www.kdenlive.org/
">kdenlive
</a
> og
5421 <a href=
"http://www.openshotvideo.com/
">openshot
</a
>, for å nevne
5422 noen. De er ikke stabile nok. Når elevene kommer med filmsnutter de
5423 ønsker og jobbe med, så godtar ikke programmene filene, og når elevene
5424 jobber med redigering bare krasjer programmene uten forvarsel. Det er
5425 for vanskelig å få noe som bare fungerer ut av boksen her. Når en elev
5426 plugger inn et videokamera eller fotoapparat så er det alltid noe som
5427 ikke vil fungere. Programmene godtar ikke format, godtar ikke
5428 kameraet, osv., osv. Det er dessverre med på og dra ned en positiv
5429 opplevelse av bruk av fri programvare.
</p
>
5431 <p
>Man må ofte bruke flere en et video redigerings program før og få
5432 fullført en ønsket oppgave.
</p
>
5434 <p
>Eksempel:
</p
>
5436 <p
>Hvis det ene programmet ikke vil ta i mot videofilen klarer et
5437 annet det, men det programmet som klarer det kan ikke gjøre de samme
5438 oppgavene som det programmet som ikke ville ta i mot filen,
5439 Tilsvarende er det med foto, man må bruke flere programmer for å få
5440 et ferdig resultat. Til dags dato har jeg enda ikke funnet et video-
5441 og fotoprogram som kan tilfredstillende fullføre en oppgave.
</p
>
5443 <p
>Så man kan klare og fullføre en oppgave, men i verste fall må man
5444 innom
3-
4 programmer for å få det til. Så jeg har enda ikke til dags
5445 dato sett at et program fungere
100% til alt.
</p
>
5447 <p
>Det programmet jeg har best erfaring til er
5448 <a href=
"http://cinelerra.org/
">cinelerra
</a
>, men dessverre har det
5449 også tendenser og krasje av og til uten grunn.
</p
>
5451 Lydsystemet kan også være et mareritt. Konkret snakker jeg om når du
5452 bruker for eksempel et smartboard, så følger det med USB-lydkort på
5453 disse. Problemet ligger her i at systemet ikke vil velge rett
5454 lydkort, så man må inn med padevchooser for å sette opp PulseAudio
5455 til og velge at USB-lydkortet skal brukes. Det blir for tungvindt for
5456 lærene, de ønsker at ting skal fungere med en gang. (min løsning på
5457 det problemet ble at jeg måtte deaktivere lydkortet som fantes på
5458 maskinen) men da må man bestandig slå på smartboard-tavla.
5460 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
5462 Programmene jeg bruker mest av er: Rosegarden, jack, qsynth, audacity,
5463 k3b, openttd og libreoffice.
5465 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
5466 skoler til å ta i bruk fri programvare?
</strong
></p
>
5468 Jeg tror det må bevisstgjøring av Skolene til, dvs. reklamere høylytt
5469 og fortelle og vise de andre skolene at frie programvarer faktisk
5470 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
5481 publish another interview with the people behind
5482 <a href=
"http://www.skolelinux.org/
">Debian Edu and Skolelinux
</a
>.
5483 This time it is one of our German developers, who have helped out over the
5484 years to make sure both a lot of major but also a lot of the minor
5485 details get right before release.
5487 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
5489 <p
>My name is Jürgen Leibner, I
'm
49 years old and living in
5490 Bielefeld, a town in northern Germany. I worked nearly
20 years as
5491 certified engineer in the department for plant design and layout of an
5492 international company for machinery and equipment. Since
2011 I
'm a
5493 certified technical writer (tekom e.V.) and doing technical
5494 documentations for a steam turbine manufacturer. From April this year
5495 I will manage the department of technical documentation at a
5496 manufacturer of automation and assembly line engineering.
</p
>
5498 <p
>My first contact with linux was around
1993. Since that time I used
5499 it at work and at home repeatedly but not exclusively as I do now at
5500 home since
2006.
</p
>
5502 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5503 project?
</strong
></p
>
5505 <p
>Once a day in the early year of
2001 when I wanted to fetch my
5506 daughter from primary school, there was a teacher sitting in the
5507 middle of
20 old computers trying to boot them and he failed. I helped
5508 him to get them booting. That was seen by the school director and she
5509 asked me if I would like to manage that the school gets all that old
5510 computers in use. I answered:
"Yes
".
</p
>
5512 <p
>Some weeks later every of the
10 classrooms had one computer
5513 running Windows98. I began to collect old computers and equipment as
5514 gifts and installed the first computer room with a peer-to-peer
5515 network. I did my work at school without being payed in my spare time
5516 and with a lot of fun. About one year later the school was connected
5517 to Internet and a local area network was installed in the school
5518 building. That was the time to have a server and I knew it must be a
5519 Linux server to be able to fulfil all the wishes of the teachers and
5520 being able to do this in a transparent and economic way, without extra
5521 costs for things like licence and software. So I searched for a
5522 school server system running under Linux and I found a couple of
5523 people nearby who founded
'skolelinux.de
'. It was the Skolelinux
5524 prerelease
32 I first tried out for being used at the school. I
5525 managed the IT of that school until the municipal authority took over
5526 the IT management and centralised the services for all schools in
5527 Bielefeld in December of
2006.

>What do you see as the advantages of Skolelinux/Debian
5530 Edu?
</strong

5532 <p
>When I
'm looking back to the beginning, there were other advantages
5533 for me as today.
</p
>
5535 <p
>In the past there were advantages like:
</p
>
5539 <li
>I don
't need to buy it so it generates no costs to the school as
5540 they had little money to spent for computers and software.
</li
>
5542 <li
>It has a licence which grands all rights to use it without
5545 <li
>It was more able to fit all requirements of a server system for
5546 schools than a Microsoft server system, even if there are only Windows
5547 clients because of it
's preconfigured overall concept of being a
5548 infrastructure solution and community for schools, not only a

>
5556 <p
>Today some of the advantages has been lost, changed or new ones
5557 came up in this way:
</p
>
5561 <li
>Most schools here do have money to buy hardware and software
5564 <li
>They are today mostly managed from central IT departments which
5565 have own concepts which often do not fit to Debian Edu concepts
5566 because they are to close to Microsoft ideology.
</li
>
5568 <li
>With the Squeeze version of Debian Edu which now uses GOsa² for
5569 management I feel more able to manage the daily tasks than with the
5570 interfaces used in the past.
</li
>
5572 <li
>It is more modular than in the past and fits even better to the
5573 different needs.
</li
>
5575 <li
>The documentation is usable and gets better every day.
</li
>
5577 <li
>More people than ever before are using Debian Edu all over the
5578 world and so the community, which is an very important part I think,
5579 is sharing knowledge and minds.
</li

5581 <li
>Most, maybe all, of the technical requirements for schools are
5582 solved today by Debian Edu.

5592 their product portfolio for serving schools with concepts or even
5593 whole municipality areas.

5606 computer. On my laptop I use Debian testing/sid. The applications I
5607 use on my laptop and my desktop are Open/Libre-office, Iceweasel,
5608 KMail, DigiKam, Amarok, Dolphin, okular and all the other programs I
5609 need from the KDE environment. On console I use newsbeuter, mutt,
5610 screen, irssi and all the other famous and useful tools.

5613 and mutt over ssh on the console, file services with samba, NFS,

>Da jeg googlet etter noe annet kom jeg tilfeldigvis over
5633 <a href=
"http://www.duo.uio.no/sok/work.html?WORKID=
58309">en
5634 hovedfagsoppgave
</a
> ved Universitetet i Oslo som diskuterer verdien
5635 av GPLs fire friheter for brukerne av IT-systemer. Jeg ble fascinert
5636 over det som presenteres der. Her er sammendraget:
</p
>
5638 <p
><blockquote
>
5640 <p
>Motivasjonen til å skrive denne oppgaven er en personlig undring
5641 over hvorfor det primært, og ofte eksklusivt, fokuseres på det
5642 økonomiske aspektet ved utredninger om fri programvare er et godt valg
5643 for det offentlige. Fri og produsenteid programvare bygger på
5644 fundamentalt forskjellige ideologier som kan ha implikasjoner utover
5645 økonomiske kostnader. Kunnskapskulturen som er med på å definere fri
5646 programvare er basert på åpenhet, og er en verdi i seg selv.
</p
>
5648 <p
>Oppgavens tema er programvarelisensen GPL og frihet. GPL-lisensiert
5649 programvare gir visse friheter i forhold til produsenteid
5650 programvare. Mitt spørsmål er om, og eventuelt i hvilken utstrekning,
5651 disse frihetene blir benyttet av ulike brukere og hvordan de
5652 manifesterer seg for disse brukerne. Sentrale spørsmål i oppgaven
5656 <li
>Hvordan fordeles handlekraft gjennom lisensieringen av programvaren?
</li
>
5657 <li
>Hvilke konsekvenser har programvarelisensen for de ulike brukere?
</li
>
5660 <p
>Fri programvare gir blant annet brukeren mulighet til å studere og
5661 modifisere kildekoden. Denne formen for frihet erverves gjennom
5662 kunnskap og krever at brukeren også er en ekspert. Hva skjer med
5663 frihetene til GPL når sluttbrukeren er en annen? Dette diskuteres i
5664 dialog med informantene.
</p
>
5666 <p
>Jeg har i denne oppgaven samlet inn intervjudata fra IKT-ansvarlige
5667 ved grunnskolene i Nittedal kommune, driftsansvarlig og IKT-veilederen
5668 for skolene i kommunen, samt IKT-koordinator for utdanning i Akershus
5669 fylkeskommune og bokmåloversettere av OpenOffice.org. Den empiriske
5670 delen av oppgaven er delt inn i to seksjoner; den første omhandler
5671 operativsystemet Skolelinux, den andre kontorprogrampakken
5672 OpenOffice.org.
</p
>
5674 <p
>Som vi vil se gir GPL lokal frihet og kontroll gjennom omfordeling
5675 av makt fra produsent til bruker. Brukerens makt analyseres gjennom
5676 begrepene brukermedvirkning og handlingsfrihet. Det blir også lagt
5677 vekt på strukturelle forhold rundt bruken av teknologi, og spesielt de
5678 økonomiske begrepene nettverkseksternaliteter, innlåsing og
5679 stiavhengighet. Dette er begreper av spesiell nytte når objektet som
5680 omsettes eller distribueres er et kommunikasjonsprodukt, fordi verdien
5681 til et slikt gode for en potensiell bruker avhenger av antall
5682 eksisterende brukere av godet. I tilknytning til denne problematikken
5683 inneholder oppgaven også en diskusjon rundt åpne standarder og
5686 <p
>Oppgaven konkluderer med at de «fire frihetene» som GPL-lisensen er
5687 laget for å beskytte er av avgjørende betydning for bruken av
5688 OpenOffice.org og Skolelinux, i Akershus fylkeskommune såvel som i
5689 skolene i Nittedal. Distribusjonen av handlekraft er ikke helt
5690 symmetrisk. Det er først og fremst de profesjonelle utviklerne i

>Behind
<a href=

">Debian Edu and
5711 Skolelinux
</a
> there are a lot of people doing the hard work of
5712 setting together all the pieces. This time I present to you Andreas
5713 Mundt, who have been part of the technical development team several
5714 years. He was also a key contributor in getting GOsa and Kerberos set
5715 up in the recently released
5716 <a href=

5719 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
5721 <p
>My name is Andreas Mundt, I grew up in south Germany. After
5722 studying Physics I spent several years at university doing research in
5723 Quantum Optics. After that I worked some years in an optics company.
5724 Finally I decided to turn over a new leaf in my life and started
5725 teaching
10 to
19 years old kids at school. I teach math, physics,
5726 information technology and science/technology.
</p
>
5728 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5729 project?
</strong
></p
>
5731 <p
>Already before I switched to teaching, I followed the Debian Edu
5732 project because of my interest in education and Debian. Within the
5733 qualification/training period for the teaching, I started
5734 contributing.
</p
>
5736 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5737 Edu?
</strong
></p
>
5739 <p
>The advantages of Debian Edu are the well known name, the
5740 out-of-the-box philosophy and of course the great free software of the
5741 Debian Project!
</p
>
5743 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
5744 Edu?
</strong
></p
>
5746 <p
>As every coin has two sides, the out-of-the-box philosophy has its
5747 downside, too. In my opinion, it is hard to modify and tweak the
5748 setup, if you need or want that. Further more, it is not easily
5749 possible to upgrade the system to a new release. It takes much too
5750 long after a Debian release to prepare the -Edu release, perhaps
5751 because the number of developers working on the core of the code is
5752 rather small and often busy elsewhere.
</p
>
5754 <p
>The
<a href=
"http://wiki.debian.org/DebianLAN
">Debian LAN
</a
>
5755 project might fill the use case of a more flexible system.
</p
>
5757 <p
><strong
>Which free software do you use daily?
</strong
></p
>
5759 <p
>I am only using non-free software if I am forced to and run Debian
5760 on all my machines. For documents I prefer LaTeX and PGF/TikZ, then
5761 mutt and iceweasel for email respectively web browsing. At school I
5762 have Arduino and Fritzing in use for a micro controller project.
</p
>
5764 <p
><strong
>Which strategy do you believe is the right one to use to
5765 get schools to use free software?
</strong
></p
>
5767 <p
>One of the major problems is the vendor lock-in from top to bottom:
5768 Especially in combination with ignorant government employees and
5769 politicians, this works out great for the
"market-leader
". The school
5770 administration here in Baden-Wuerttemberg is occupied by that vendor.
5771 Documents have to be prepared in non-free, proprietary formats. Even
5772 free browsers do not work for the school administration. Publishers
5773 of school books provide software only for proprietary platforms.
</p
>
5775 <p
>To change this, political work is very important. Parts of the
5776 political spectrum have become aware of the problem in the last years.
5777 However it takes quite some time and courageous politicians to
'free
'
5778 the system. There is currently some discussion about
"Open Data
" and
5779 "Free/Open Standards
". I am not sure if all the involved parties have
5780 a clue about the potential of these ideas, and probably only a
5781 fraction takes them seriously. However it might slowly make free
5782 software and the philosophy behind it more known and popular.

>Recently I have spent time with
5849 <a href=
"http://www.slxdrift.no/
">Skolelinux Drift AS
</a
> on speeding
5850 up a
<a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>
5851 Lenny installation using LTSP diskless workstations, and in the
5852 process I discovered something very surprising. The reason the KDE
5853 menu was responding slow when using it for the first time, was mostly
5854 due to the way KDE find application icons. I discovered that showing
5855 the Multimedia menu would cause more than
20 000 IP packages to be
5856 passed between the LTSP client and the NFS server. Most of these were
5858 NFS LOOKUP calls, resulting in a NFS3ERR_NOENT response. Because the
5859 ping times between the client and the server were in the range
2-
20
5860 ms, the menus would be very slow. Looking at the strace of kicker in
5861 Lenny (or plasma-desktop i Squeeze - same problem there), I see that
5862 the source of these NFS calls are access(
2) system calls for
5863 non-existing files. KDE can do hundreds of access(
2) calls to find
5864 one icon file. In my example, just finding the mplayer icon required
5865 around
230 access(
2) calls.
</p
>
5867 <p
>The KDE code seem to search for icons using a list of icon
5868 directories, and the list of possible directories is large. In
5869 (almost) each directory, it look for files ending in .png, .svgz, .svg
5870 and .xpm. The result is a very slow KDE menu when /usr/ is NFS
5871 mounted. Showing a single sub menu may result in thousands of NFS
5872 requests. I am not the first one to discover this. I found a
5873 <a href=
"https://bugs.kde.org/show_bug.cgi?id=
211416">KDE bug report
5874 from
2009</a
> about this problem, and it is still unsolved.
</p
>
5876 <p
>My solution to speed up the KDE menu was to create a package
5877 kde-icon-cache that upon installation will look at all .desktop files
5878 used to generate the KDE menu, find their icons, search the icon paths
5879 for the file that KDE will end up finding at run time, and copying the
5880 icon file to /var/lib/kde-icon-cache/. Finally, I add symlinks to
5881 these icon files in one of the first directories where KDE will look
5882 for them. This cut down the number of file accesses required to find
5883 one icon from several hundred to less than
5, and make the KDE menu
5884 almost instantaneous. I
'm not quite sure where to make the package
5885 publicly available, so for now it is only available on request.
</p
>
5887 <p
>The bug report mention that this do not only affect the KDE menu
5888 and icon handling, but also the login process. Not quite sure how to
5889 speed up that part without replacing NFS with for example NBD, and
5890 that is not really an option at the moment.

5929 <p
>I
've studied Mathematics at the university
'Ruhr-Universität
' in
5930 Bochum, Germany. Since
1981 I
'm working as a teacher at the school
5931 "<a href=
"http://www.westfalenkolleg-dortmund.de/
">Westfalen-Kolleg

5933 the opportunity to get further education in order to do the school
5934 examination
'Abitur
', which will allow to study at a university. This
5935 second chance is of value for those who want a better job perspective
5936 or failed to get a higher school examination being teens.
</p
>
5938 <p
>Besides teaching I was involved in developing online courses for a
5939 blended learning project called
'abitur-online.nrw
' and in some other
5940 information technology related projects. For about ten years I
've been
5941 teacher and coordinator for the
'abitur-online
' project at my
5942 school. Being now in my early sixties, I
've decided to leave school at
5943 the end of April this year.
</p

5945 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5946 project?
</strong
></p
>
5948 <p
>The first information about Skolelinux must have come to my
5949 attention years ago and somehow related to LTSP (Linux Terminal Server
5950 Project). At school, we had set up a network at the beginning of
1997
5951 using Suse Linux on the desktop, replacing a Novell network. Since
5952 2002, we used old machines from the city council of Dortmund as thin
5953 clients (LTSP, later Ubuntu/Lessdisks) cause new hardware was out of
5954 reach. At home I
'm using Debian since years and - subscribed to the
5955 Debian news letter - heard from time to time about Skolelinux. About
5956 two years ago I proposed to replace the (somehow undocumented and only
5957 known to me) system at school by a well known Debian based system:
5958 Skolelinux.
</p
>
5960 <p
>Students and teachers appreciated the new system because of a
5961 better look and feel and an enhanced access to local media on thin
5962 clients. The possibility to alter and/or reset passwords using a GUI
5963 was welcomed, too. Being able to do administrative tasks using a GUI
5964 and to easily set up workstations using PXE was of very high value for
5965 the admin teachers.

>
5967 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5968 Edu?
</strong

5970 <p
>It
's open source, easy to set up, stable and flexible due to it
's
5971 Debian base. It integrates LTSP out-of-the-box. And it is documented!
5972 So it was a perfect choice.
</p
>
5974 <p
>Being open source, there are no license problems and so it
's
5975 possible to point teachers and students to programs like
5976 OpenOffice.org, ViewYourMind (mind mapping) and The Gimp. It
's of
5977 high value to be able to adapt parts of the system to special needs of
5978 a school and to choose where to get support for this.

6015 <p
>Det er store forskjeller på skolenes digitale tilstand, viser
6016 undersøkelsen Monitor
2011 som er laget på oppdrag fra
6017 Kunnskapsdepartementet. Dette har ført til debatt om PC-tilgangen i
6018 skolen, og om de med Linux i skolen gjør det bedre bedre eller
6019 dårligere enn snittet i landet.
</p

6021 <p
>Nå har vi tallene. Skoler med Linux har
36% større PC-tetthet en
6022 landsgjennomsnittet. På spørsmål hvorfor skoler med Linux har større
6023 PC-tetthet, observerer Paul Reidar Løsnesløkken som er IKT-konsulent i
6024 Nord-Odal:
</p

6026 <p
><blockquote
>"Vi erfarer at klienter med Skolelinux har god funksjon
6027 til de er
8 til
10 år gamle. Dette er omtrent dobbelt så lenge som
6028 andre løsninger, og skolene får mer datautstyr for
6029 pengene.
"</blockquote
></p
>
6031 <p
>Undersøkelsen baserer seg på
56 skoler som har gjort det offentlig
6032 at de kjører Skolelinux eller annen Linux-utgave. De kan også ha PC-er
6033 med Windows i skolenettet. Når en sammenligner PC-tetthetene på
6034 skolene i kommunene Flora, Harstad, Kongsvinger, Narvik, Nittedal,
6035 Nord-Odal og Randaberg, er det i snitt
2,
28 elev pr. PC på skolene med
6036 Linux. På landsbasis er det
3.11 elev per PC i grunnskolen, i følge
6037 side
95 i Monitor-rapporten for

36% større
6038 PC-tetthet i skoler med Linux.

6042 <p
>Skolelinux har til hensikt å gi alle barn full tilgang til
6043 skoleaktuelle dataprogram på sitt eget morsmål. Derfor følger det med
6044 godt over
100 skoleaktuelle programmene laget for læring. De fleste
6045 programmene er oversatt til over
50 språk. Elevene skal også kunne
6046 studere alle sider av dataprogrammene. Derfor følger også kildekode
6047 med. Elever med interesse kan lære av eksperter som har laget
6048 systemet. Dette med enkelt programmering i læreprogram som KTurtle,
6049 til profesjonelle verktøy som Qt Creator eller Java.
</p

6051 <p
>Skolelinux er laget for sentralisert drift, der alt teknisk
6052 administrasjon av alle skolene kan gjøres sentralt fra kommunehuset
6053 eller sentralt i en region. F.eks. drifter to-tre personer
70.000
6054 skoledatamaskiner på
200 skoler i delstaten Extremadura i
6055 Spania. Etter velykket bruk av Debian Edu i skolen, legger delstaten
6056 over til Debian på
40.000 datamaskiner i administrasjonen. Det er idag

>I serien med intervjuer av folk i
6096 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet, får vi
6097 denne gangen høre fra en IKT-ansvarlig som har brukt Skolelinux i
6098 mange år, og vært storfornøyd med erfaringene så langt.
</p
>
6100 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
6102 <p
>Mitt navn er Roy-Arne Myhre og jeg er
42 år. Jeg er ansatt hos
6103 <a href=
"http://www.sandskole.no/
">Sand skole
</a
> (Balsfjord kommune)
6104 og har stort sett vært det siden
1990. Jeg er IKT ansvarlig ved
6105 skolen i
40% stilling –
10% undervisning – musikk.
</p
>
6107 <p
>Ved skolen er det ca
100 elever og ca
18 lærere +
4 assistenter i
6108 hele og delte stillinger. Alle lærerne har bærbar PC (dessverre med
6109 Win Vista) – assistenter har tilgang til egne. Vi benytter Fronter i
6110 det daglige arbeidet. Vi har ca
90 elevmaskiner som fungerer til
6111 daglig opp mot Linux server (XFCE) som driftes av
6112 <a href=
"http://www.bzz.no/
">BzzWare AS
</a
> via nett. Maskinparken
6113 består kun av brukt utstyr for elevene – og noe av dette begynner å
6114 bli vel gammelt selv som halvtykke klienter.
</p
>
6116 <p
><strong
>Hvordan kom du i kontakt med
6117 Skolelinux-prosjektet?
</strong
></p
>
6119 <p
>Vi kom første gang i kontakt med Skolelinux rundt
1997. Den gang
6120 var det oppstart-disketter i hver maskin, ikke mulighet for lyd og
6121 video, gamle nettverkskort og mye plundring. Vi hadde en ihuga
6122 forelder med som pådriver, forsker og inspirator for hele opplegget.
6123 Selv ante jeg knapt at Skolelinux fantes, men han var av den
6124 utforskende typen, og fikk både meg og skolelederen i trua på at dette
6125 var ting som kunne fungere. Etter dette har det gått gradvis
6126 framover; flere maskiner er hentet inn gjennom bl.a
6127 <a href=
"http://www.greentech.no/
">Greentech
</a
> og utrangert utstyr
6128 fra høgskole / Avinor og private givere. Når maskinene ble for trege
6129 for nye Windows-versjoner, sto vi klare til å putte dem i nettverket
6130 vårt. Dette betyr at vi i dag har
1:
1 dekning av maskiner på
6131 ungdomstrinnet og bedre enn
1:
2 på barnetrinnet. Dette er vi veldig
6132 fornøyd med, og vi kan ikke se for oss hverdagen som ville vært
6133 alternativet ved bruk av Windows med sine lisenser pr. Bruker/maskin.
6134 Da ville vi nok vært tilbake til
1-
2 maskiner pr klasserom med de
6135 negative konsekvenser det ville hatt for undervisningsformene våre. Vi
6136 kan ha en hel klasse i prosjektjobbing eller individuell jobbing
6137 samtidig – vi kan avholde tentamen og eksamen uten
6138 logistikkproblemer.
</p
>
6140 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6142 Hvor skal jeg begynne... Stabiliteten er et nøkkelord - det bare
6143 virker. Har du først fått en server med Skolelinux opp og gå, så må
6144 det en maskinarefeil eller sabotasje til for å stoppe den. Det at man
6145 kan bruke eldre maskiner som normalt sett ville gått på dynga, er også
6146 glimrende - billig for skoler med dårlig økonomi og bra for miljøet
6147 siden vi gjenbruker utstyr i stedet for å skaffe nytt. Vi ville aldri
6148 hatt mulighet til å operere med det maskinantallet vi har pr i dag
6149 hvis det ikke var for Skolelinux - så tilgjengelighet er et annet
6150 nøkkelord. Et tredje moment er sikkerhet og brukertilgang. Alle
6151 brukerer opererer med egne brukernavn og passord, samt egne
6152 brukerområder som kan tilpasses for både enbrukertilgang og for
6153 samarbeid med andre.
6155 Elever har godt av å se at det finnes andre alternativer enn de som
6156 storindustrien selger på lisensbasis - på den måten trenes de opp til
6157 å se flere muligheter og å foreta valg ut fra flere opsjoner.
6159 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6161 <p
>Ulempene med Skolelinux er nok utbredelsen og mangelen på kjennskap
6162 til dette i skolenorge. De som skal ta økonomiske avgjørelser rynker
6163 på nesen og vil gå for det kjente og «sikre» selv om det koster mye
6164 mer. Man får rett og slett litt hetta av å ikke kunne noe – og unngår
6165 dette for enhver pris.
</p
>
6167 <p
>I tillegg er mye av linux-systemet administrert av tekstkommandoer
6168 og er lite intuitiv/visuell for oss som ikke er «inne i»
6169 kildekodene». Så problemet er nok mye godt at de som
6170 utarbeider/drifter Skolelinux ikke helt klarer å sette seg ned på
6171 skoleadministratorens nivå når det gjelder problemer og
6172 utfordringer. Men dette er nok en utfordring alle administratorer
6173 sliter med uansett OS.
</p
>
6175 <p
>Derfor har vi valgt å støtte oss til BzzWare AS for assistanse i
6176 drifta slik at jeg har kunnet konsentrere meg mer om kabling, skifting
6177 av komponenter, veiledning av lærere og elever, vedlikehold av
6178 skrivere og annen daglig drift.
</p
>
6180 <p
>Elevene mestrer Skolelinux helt fint. Så lenge Internett
6181 (Iceweasel) og Libreoffice (Openoffice) fungerer er
90% av
6182 skolehverdagen velfungerende. I tillegg brukes jo en del av den
6183 pedagogiske programpakken bla. i forhold til matematikk og geografi,
6184 men det er såpass mye bra på nett om dagen, så disse programmene er
6185 mer som krydder å regne.
</p
>
6187 <p
>Jeg skulle ønske neste versjon av Skolelinux kunne komme litt
6188 mindre stappet med programmer, for halvparten blir aldri brukt, eller
6189 fungerer ikke uansett. Hva med et pedagogisk panel av lærere/IKT
6190 ansvarlige som kunne sagt: disse programmene skal være standard, så
6191 får resten være slike man kan legge til ved behov – det kan lett bli
6192 en jungel å bevege seg i.
</p
>
6194 <p
>Jeg ønsker meg også en mer grafisk versjon av
6195 <a href=
"http://bzz.no/lwat/trac/trac.cgi
">Lwat
</a
> hvor man kan krysse
6196 ut de som f.eks ikke skal ha internett-tilgang en dag pga
6197 eksamen/tentamen, samt en noe enklere brannmurløsning hvor man kan
6198 stenge for en del (få) sider på en enkel måte. Jeg liker godt
6199 Skolelinux sin ideologi om at filteret skal trenes i hodet på eleven –
6200 men av og til skulle jeg ønske at f.eks Facebook og Youtube kunne vært
6201 koblet vekk en periode for å få bedre utnyttelse av tid og
6202 ressurser. Disse to nettstedene er nok mye av årsaken til at mange
6203 lærere holder igjen databruken noe mer enn man kunne ønske.
</p
>
6205 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
6207 Jeg benytter nesten bare fri programvare til daglig. LibreOffice,
6208 Iceweasel (Firefox), Thunderbird til e-post og Gimp til
6209 bildebehandling. Vi har PHP-Nuke-oppsatt hjemmeside. Det eneste som
6210 jeg ikke har fått helt til enda er videoredigering - her må man vel
6211 innrømme at Mac er hakket over, men da er vi igjen over på å se hva
6212 som egner seg best, og ta valg ut fra det. Folk flest lever i
6213 villfarelsen om at regneark HETER Excel og tekstbehandling HETER
6214 Word. Dette er en misforståelse som jeg bruker mye energi på å
6215 diskutere og
"åpne sinn
" på Microsoft-slaver. Dessverre er det mange
6216 IKT-ansvarlige som også har låst seg på at det eneste saliggjørende er
6217 Bill G sine produkter.
6219 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
6220 skoler til å ta i bruk fri programvare?
</strong
></p
>
6222 <p
>For å komme lenger i utbredelsen av Skolelinux tror jeg det må mer
6223 fram i nasjonale medier, samt komme bedre fram hva økonomien i dette
6224 valget vil være – samt mulighetene. Fri programvare er en berikelse og
6225 gjør oss i stand til å utføre arbeidet i skolen uten å måtte legge
6226 igjen tusener på tusener i Bill Gates lomme.. Få ETT nettsted med
6227 forståelig veiledning av installasjon/oppgradering og ETT forum med
6228 konkrete feilrettinger og problemer, så tror jeg vi kunne kommet et
6229 par skritt framover. Ellers tror jeg bare at ildsjelene må fortsette å
6230 skinne – kanskje flere enn oss følger etter på veien.

>Den siste uka har det vært en del skriverier om hvor store
6265 forskjeller det er mellom skolene når det gjelder digital kompetanse.
6267 <a href=
"http://www.digi.no/
891660/bekymret-for-it-i-skolen
">oppslaget
6268 i Digi
</a
>. Diskusjonen fikk meg til å bli litt nysgjerrig på om
6269 Linux-skoler har større PC-tettet enn snittet i landet. Grunnlaget
6270 for diskusjonen har vært undersøkelsen
6271 <a href=
"https://iktsenteret.no/ressurser/monitor-
2011-skolens-digitale-tilstand
">Monitor
6272 2011</a
>, som bruker informasjon fra
6273 <a href=
"https://www.wis.no/gsi
">Grunnskolens Informasjonssystem
</a
>
6274 (GSI). GSI-data kan lastes ned fra web og jeg lastet ned en Excel-fil
6275 (intet åpen standard-valg tilgjengelig) med navn på alle skoler,
6276 hvilke kommune de befinner seg i og hvor mange elever pr. elev-PC de
6277 har rapportert inn. For å få en ide om svaret trenger jeg deretter å
6278 vite hvilke skoler i landet som bruker Linux, slik at jeg kan slå dem
6279 opp i GSI og finne ut hvor stor PC-tetthet de har.
</p
>
6281 <p
>Jeg vet om skoler i Balsfjord, Flora, Harstad, Kongsvinger, Narvik,
6282 Nittedal, Nord-Odal, Randaberg og Sunndal som bruker Skolelinux eller
6283 andre Linux-varianter. Jeg tror det er flere enn de
56 skolene jeg
6284 har klart å identifisere de siste dagene, men har ikke klart å få det
6285 bekreftet med offentlige kilder.
</p
>
6287 <p
>Monitor
2011-rapporteres side
95 forteller at det
"ifølge GSI
6288 (
20120-
2011) er det
3,
11 elever per datamaskin når vi tar med alle
6289 grunnskoler (
1.-
10.trinn)
". For de
56 Linux-skolene jeg har klart å
6290 koble mot informasjon i GSI er det
2,
28 elever per elevdatamaskin,
6291 hvilket betyr at det er
36% høyere PC-tetthet på Linux-skoler enn
6292 landsgjennomsnittet. Linux-skolen med høyest tettet blant de jeg har
6293 notert -skole er Flora ungdomsskule i Flora kommune med
0.82 elev
6294 pr. PC (
482 elever,
588 elevdatamaskiner).
</p
>
6296 <p
>Skolelinux gir datamaskiner lengre levetid, og en kan dermed få
6297 flere operative datamaskiner for samme budsjett, i tillegg til en
6298 rekke andre fordeler. Kan det være forklaringen på forskjellen?
</p
>
6300 <p
>Tallene må tas med en liten klype, da GSI ser ut til å ha endel
6301 feilføringer. Jeg synes i hvert fall en skole med
423 elever og
9
6302 elevmaskiner ser mistenkelig ut. Eller en skole med
346 elever,
0
6303 elevmaskiner, som er et annet ekstremt eksempel jeg fant.

6323 <p
>I teach ICT part time at the Rudolf Steiner School in Kings
6324 Langley, near London, UK. Previously I worked as a technical
6325 author/trainer while my children attended the school, and I also
6326 contributed to the Schoolforge UK community with the aim of
6327 encouraging UK schools to adopt free/open source software. Five or six
6328 years ago we had about
50 schools interested in some way, but we
6329 weren
't able to convert many of them into sustainable
6330 installations.
</p
>
6332 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
6333 project?
</strong
></p
>
6335 <p
>Skolelinux had two representatives at an early Edubuntu meeting in
6336 London which I attended. However at that time our school network had
6337 just been installed using CentOS, LTSP
4 and GNOME. When LTSP
5 came
6338 along we switched to Edubuntu thin client servers so now we have a
6339 mixed environment which includes Windows PCs and student laptops, as
6340 well as their MacBooks and iPads. However, the proprietary systems
6341 have always been rather problematic, and we never built a GUI for the
6342 LDAP server, so when I discovered Skolelinux is configured for all
6343 these things we decided to try it.
</p
>
6345 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
6346 Edu?
</strong
></p
>
6348 <p
>By far the biggest advantage is the Debian Edu community. Apart
6349 from that I have always believed in the same
"sustainable computing
"
6350 goals that Skolelinux is built on: installing Linux on computers which
6351 would otherwise be thrown away, to provide a reliable, secure and
6352 low-cost IT environment for schools. From my own experience I know
6353 that a part-time person can teach and manage a network of about
25
6354 Linux computers, but it would take much more of my time if we had
6355 proprietary software everywhere.

>What do you see as the disadvantages of Skolelinux/Debian
6358 Edu?
</strong
></p

6360 <p
>As a newcomer I
'm just finding out who
's who in the community and
6361 how you
're organised, and what your procedures are for dealing with
6362 various things such as editing manual pages and so-on. The only
6363 English language mailing list seems to be for developers as well as
6364 users, so my inbox needs heavy pruning each day!
</p
>
6366 <p
><strong
>Which free software do you use daily?
</strong
></p
>
6368 <p
>Besides the software already mentioned at school we use Samba,
6369 OpenLDAP, CUPS, Nagios and Dansguardian for the network, and on the
6370 desktops we have LibreOffice, Firefox, GIMP and Inkscape. At home I
6371 use Ubuntu and an Android
4 eePad Transformer (but I
'm not sure if
6372 that counts...)
</p
>
6374 <p
><strong
>Which strategy do you believe is the right one to use to
6375 get schools to use free software?
</strong
></p
>
6377 <p
>That
's a tough question! For very many years UK schools installed
6378 and taught only proprietary software, so that at the highest levels
6379 the notion of
"computer
" means simply
"proprietary office
6380 applications
". However, schools today are experiencing budget
6381 constraints, and many are having to think hard about upgrading Windows
6382 XP. At the same time, we have students showing teachers how to use
6383 iPads, MacBooks and Android, so the choice of operating system is no
6384 longer quite so automatic. What is more, our government at last
6385 realised that we need people with programming skills, so they
're
6386 putting coding back in the curriculum! And it
's encouraging that the
6387 first
10,
000 Raspberry Pi units sold out in
2 hours.
</p
>
6389 <p
>I don
't really know what strategy is going to get UK schools to use
6390 free software, but building an active community of Skolelinux/Debian
6391 Edu users in this country has to be part of it.

>Documentation in Debian Edu is provided in several languages, and
6401 it is important to make it both easy to contribute and to keep the
6402 translated versions in sync. To do this we have come up with what we
6403 believe is a very efficient work flow.
</p

6407 <li

6408 <a href=

</a

6409 <a href=

6411 docbook XML.
</li
>
6413 <li
>This docbook document is given to po4a to extract a gettext style
6414 .pot file with the content, which in turn is used to create .po files
6415 with the translated text.
</li
>
6417 <li
>The .po files are given to translators, and they can always tell
6418 which part of the original wiki document is new or changed. They can
6419 use their normal translation tools like lokalize or poedit to write
6420 the translation. There is even a system in place to handle translated
6423 <li
>The translated .po files are combined with the original docbook
6424 XML document using po4a to create a translated docbook document.
</li
>
6426 <li
>The final step is to use all the generated docbook files and
6427 create PDF and HTML version of the original and translated documents.

6494 <p
>Jeg hørte om det først når jeg jobbet i Redpill Linpro. Men jeg
6495 har også en datter som går på en friskole, som også bruker Skolelinux.
6496 Som kjent har ikke friskoler de samme økonomiske rammebetingelsene som
6497 offentlige skoler, så for dem var det det absolutt beste alternativet.
6498 De anser også Skolelinux som et stabilt system, som bare går og går (i
6499 motsetning til det lille Windows-baserte nettverket de har på
6500 admin-siden).

6504 <p

6505 lydløse og raskere arbeidsstasjoner som er bedre i klasserommet.
6506 Lengre levetid på PC
'er. Store besparelser på maskinvare og drift. Og
6507 så klart fjerning av alle lisenskostnader. Personlig synes jeg også at
6508 mange av programmene er bedre enn alternativene. Men dette er ofte en
6509 smakssak og avhengig om man må ha det man er vant til fra før.

>For lite kjentskap til løsningen. Noen ganger for dårlig
6514 kompatibilitet med arbeidsstasjoners/bærbare maskiner sine
6515 nettverksdrivere eller skjermkort. Men dette løser vi i skolene ved
6516 standardisering. Ellers er det få, om nesten ingen, av de kjente
6517 maskinvare / infrastruktur leverandørene til fylkes- / kommuner som
6518 tilbyr denne plattformen. Skal dette endre seg så må kommunene selv
6519 sette slike krav til leverandørene.

6523 <p
>Har brukt OpenOffice.org siden starten (

6531 <p
>Fortsette å presentere flere av de gode eksemplene hvor Debian Edu
6532 / Skolelinux brukes i kommuner og enkeltskoler. Vi må få bedre frem
6533 at det er mulig tilknytte både Windows og Mac klienter på denne
6534 plattformen (selv om det vil øke driftskostnadene). Dette gjøres
6535 mange steder. Spesielt er det mange lærere som ønsker å bruke
6536 Windows/Mac-bærbare, gjerne som sin private PC også. Det er også mulig
6537 for kommunen å integrere med Active Directory i stedet for OpenLDAP
6538 som kommer med ut av boksen (selv om også dette øker kostnadene).
6539 Dette vil muligens bidra til å fjerne noe motstand hos noen
6540 potensielle brukere / driftpersonell for å ta i bruk noe
6541 nytt. Fremveksten av mobile brukere og nettbrett går i vår favør.
6542 Brukerne blir kjent og vant til flere nye operativsystemer /
6543 brukergrensesnitt. Så utviklerfellesskapet bør jobbe videre med å
6544 integrere flere nye klienttyper, som ultra lav-kostklienter og
6545 nettbrett (blant annet fri programvare-alternativet

>Inspired by
<a href=
"http://raphaelhertzog.com/tag/interview/
">the
6577 interview series
</a
> conducted by Raphael, I started a Norwegian
6578 interview series with people involved in the Debian Edu / Skolelinux
6579 community. This was so popular that I believe it is time to move to a
6580 more international audience.
</p
>
6582 <p
>While
<a href=
"http://www.skolelinux.org/
">Debian Edu and
6583 Skolelinux
</a
> originated in France and Norway, and have most users in
6584 Europe, there are users all around the globe. One of those far away
6585 from me is Nigel Barker, a long time Debian Edu system administrator
6586 and contributor. It is thanks to him that Debian Edu is adjusted to
6587 work out of the box in Japan. I got him to answer a few questions,
6588 and am happy to share the response with you. :)
6591 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
6593 <p
>My name is Nigel Barker, and I am British. I am married to Yumiko,
6594 and we have three lovely children, aged
15,
14 and
4(!) I am the IT
6595 Coordinator at Hiroshima International School, Japan. I am also a
6596 teacher, and in fact I spend most of my day teaching Mathematics,
6597 Science, IT, and Chemistry. I was originally a Chemistry teacher, but
6598 I have always had an interest in computers. Another teacher teaches
6599 primary school IT, but apart from that I am the only computer person,
6600 so that means I am the network manager, technician and webmaster,
6601 also, and I help people with their computer problems. I teach python
6602 to beginners in an after-school club. I am way too busy, so I really
6603 appreciate the simplicity of Skolelinux.
</p
>
6605 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
6606 project?
</strong
></p
>
6608 <p
>In around
2004 or
5 I discovered the ltsp project, and set up a
6609 server in the IT lab. I wanted some way to connect it to our central
6610 samba server, which I was also quite poor at configuring. I discovered
6611 Edubuntu when it came out, but it didn
't really improve my setup. I
6612 did various desperate searches for things like
"school Linux server
"
6613 and ended up in a document called
"Drift
" something or other. Reading
6614 there it became clear that Skolelinux was going to solve all my
6615 problems in one go. I was very excited, but apprehensive, because my
6616 previous attempts to install Debian had ended in failure (I used
6617 Mandrake for everything - ltsp, samba, apache, mail, ns...). I
6618 downloaded a beta version, had some problems, so subscribed to the
6619 Debian Edu list for help. I have remained subscribed ever since, and
6620 my school has run a Skolelinux network since Sarge.
</p
>
6622 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
6623 Edu?
</strong
></p
>
6625 <p
>For me the integrated setup. This is not just the server, or the
6626 workstation, or the ltsp. Its all of them, and its all configured
6627 ready to go. I read somewhere in the early documentation that it is
6628 designed to be setup and managed by the Maths or Science teacher, who
6629 doesn
't necessarily know much about computers, in a small Norwegian
6630 school. That describes me perfectly if you replace Norway with
6633 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
6634 Edu?
</strong
></p
>
6636 <p
>The desktop is fairly plain. If you compare it with Edubuntu, who
6637 have fun themes for children, or with distributions such as Mint, who
6638 make the desktop beautiful. They create a good impression on people
6639 who don
't need to understand how to use any of it, but who might be
6640 important to the school. School administrators or directors, for
6641 instance, or parents. Even kids. Debian itself usually has ugly
6642 default theme settings. It was my dream a few years back that some
6643 kind of integration would allow Edubuntu to do the desktop stuff and
6644 Debian Edu the servers, but now I realise how impossible that is. A
6645 second disadvantage is that if something goes wrong, or you need to
6646 customise something, then suddenly the level of expertise required
6647 multiplies. For example, backup wasn
't working properly in Lenny. It
6648 took me ages to learn how to set up my own server to do rsync backups.
6649 I am afraid of anything to do with ldap, but perhaps Gosa will
6652 <p
><strong
>Which free software do you use daily?
</strong
></p
>
6654 <p
>Nowadays I only use Debian on my personal computers. I have one for
6655 studio work (I play guitar and write songs), running AV Linux
6656 (customised Debian) a netbook running Squeeze, and a bigger laptop
6657 still running Skolelinux Lenny workstation. I have a Tjener in my
6658 house, that
's very useful for the family photos and music. At school
6659 the students only use Skolelinux. (Some teachers and the office still
6660 have windows). So that means we only use free software all day every
6661 day. Open office, The GIMP, Firefox/Iceweasel, VLC and Audacity are
6662 installed on every computer in school, irrespective of OS. We also
6663 have Koha on Debian for the library, and Apache, Moodle, b2evolution
6664 and Etomite on Debian for the www. The firewall is Untangle.
</p
>
6666 <p
><strong
>Which strategy do you believe is the right one to use to
6667 get schools to use free software?
</strong
></p
>
6669 <p
>Current trends are in our favour. Open source is big in industry,
6670 and ordinary people have heard of it. The spread of Android and the
6671 popularity of Apple have helped to weaken the impression that you have
6672 to have Microsoft on everything. People complain to me much less about
6673 file formats and Word than they did
5 years ago. The Edu aspect is
6674 also a selling point. This is all customised for schools. Where is the
6675 Windows-edu, or the Mac-edu? But of course the main attraction is
6676 budget.The trick is to convince people that the quality is not
6677 compromised when you stop paying and use free software instead. That
6678 is one reason why I say the desktop experience is a weakness. People
6679 are not impressed when their USB drive doesn
't work, or their browser
6680 doesn
't play flash, for example.

>Many years ago, the
<a href=
"http://www.skolelinux.org/
">Skolelinux
6727 / Debian Edu project
</a
> initiated a student project to create a tool
6728 for making stop motion movies. The proposal came from a teacher
6729 needing such tool on Skolelinux. The project, called
"stopmotion
",
6730 was manned by two extraordinary students and won a school award and a
6731 national aware with this great project. The project was initiated and
6732 mentored by Herman Robak, and manned by the students Bjørn Erik Nilsen
6733 and Fredrik Berg Kjølstad. They got in touch with people at Aardman
6734 Animation studio and received feedback on how professionals would like
6735 such stopmotion tool to work, and the end result was and is used by
6736 animators around the globe. But as is usual after studying, both got
6737 jobs and went elsewhere, and did not have time to properly tend to the
6738 project, and it has been lingering for a few years now. Until last
6741 <p
>Last year some of the users got together with Herman, and moved the
6742 project to Sourceforge and in effect restarted the project under a new
6744 <a href=
"http://sourceforge.net/projects/linuxstopmotion/
">linuxstopmotion
</a
>.
6745 The name change was done to make it possible to find the project using
6746 Internet search engines (try to search for
'stopmotion
' to see what I
6747 mean). I
've been following
6748 <a href=
"https://lists.sourceforge.net/lists/listinfo/linuxstopmotion-community

6827 <p
>Knut Yrvin her. Jobber i Nokia med å fremme rammeverket Qt og QML
6828 med tilhørende utviklerverktøy. Rollen er som leder av
6829 friprog-samfunn. I fjor var jeg med å legge om utviklingen av Qt til
6830 åpen forvaltning. På den måten kan alle som bidrar til Qt gjøre det
6831 på like vilkår. Nå er det

">over
6833 1000 utviklere
</a
> som bidrar til Qt. Med overgangen til åpen
6834 forvaltning er utviklingen av Qt mer åpen enn Linux-kjernen.
</p
>
6836 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
6838 <p
>Jeg var en av initiativtagerne til Skolelinux i
2001. Skolene slet
6839 med både utstyr og Internett-tilgang. De klarte ikke å møte
6840 forventningene til data i skolen. Driften av PC-ene var uholdbar. Som
6841 regel hadde rektor pekt ut en ivrig lærer til å passe på PC-ene,
6842 gjerne naturfaglæreren. Mange lærere jobbet mye ubetalt overtid for å
6843 vedlikeholde
30-
40 datamaskiner på hver sin skole. Med
300 elever og
6844 lærere som brukere, blir det fort mye mer arbeid enn de
4-
8 timene de
6845 kunne bruke på PC-drift. Skolene hadde kun en femtedel av
6846 IT-budsjettet som ble brukt på PC-ene i rådhuset.
</p
>
6848 <p
>Vi erfarte at skolene hadde mye datautstyr som stod ubrukt. Skolene
6849 manglet penger til Microsoft-lisenser. Selv med solide skolerabatter,
6850 kostet Microsoft-lisensene gjerne like mye som PC-ene i seg selv over
6851 en periode på
5-
6 år.
</p
>
6853 <p
>Viktigheten av språklig mangfold og pedagogiske programmer var også
6854 viktig for oss. Vi oversatte mange skoleaktuelle programmer til
6855 nynorsk, nordsamisk og bokmål. Dette lenge før andre tok denne
6856 oppgaven seriøst. Allerede etter ett år hadde vi etablert et helt
6857 arsenal av skoleaktuelle programmer på nynorsk, bokmål og
6858 nordsamisk. Vi spredde vår ide om språklig mangfold til de andre frie
6859 prosjekter internasjonalt. Resultatene ser vi i mange land. Det er de
6860 frie programmene som kommer på brukernes morsmål. Det er en av flere
6861 gode grunner til at fri programvare som LibreOffice, VLC, KDE og
6862 Firefox konkurrerer ut godseid programvare mange steder i verden.
</p
>
6864 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6866 <p
>Fordelene er at Skolelinux tilbyr over
100 skoleaktuelle programmer
6867 på de norske språkene, uten ett øre i lisenskostnader. Systemet gir
6868 enormt lave driftskostnader med diskløse arbeidsstasjoner og bærbare
6869 med roaming. Skolelinux krever også mindre av maskinvaren.
</p
>
6871 <p
>Man kan fint kjøre systemet med
512 MB RAM på en bærbar PC sammen
6872 med en nettvideo i nettleseren og en presentasjon med
6873 LibreOffice. Konkurrerende system krever fort
2 GB RAM for å få til
6874 noe tilsvarende uten at det går ufattelig tregt. Skal man gjøre noe
6875 nyttig, krever konkurrentene til Linux mye større harddisk. Skoler har
6876 rapportert at de fort har fått
50% flere nye maskiner om de velger
6877 Linux. Dette i tillegg til de årlige besparelsene ved å unngå
6878 lisensbetaling til godseid programvare.
</p
>
6880 <p
>De lave driftskostnadene gjør at delstater i Europa har titusener
6881 av datamaskiner med Skolelinux i skolen. F.eks. er det under ti
6882 personer som drifter
70.000 PC-systemer i skolene i Extremadura i
6883 Spania. Det er slett ikke uvanlig at norske kommuner har
1500-
2000
6884 datamaskiner med Skolelinux. Driften tar ett årsverk. Slår flere
6885 kommuner seg sammen, kan de få samme sentraliserte stordriftsfordeler
6886 som delstater i Tyskland og Spania. Delstater som kjører Skolelinux
6887 på alle skolene. Bare noen få personer sentraldrifter titusenvis av
6890 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6892 <p
>Den største ulempen for Skolelinux er motstand mot Linux fra
6893 IT-sjefer i det offentlige. Dette er ledere som holder innlegg som
6894 snytt ut av evangelist-håndboka til Microsoft. Dette gjøres i ett
6895 arbeidsmarked med stor vekst i etterspørselen etter Linux-fagfolk i
6896 privat sektor. Etterspørselen har økt mer enn noe annet tekniske yrke
6897 siste tiåret. Åtte av ti ledere vil ansette Linux-fagfolk i
2012,
6898 rapporterer jobbnettstedet Dice.com på oppdrag av Linux
6899 Foundation.
</p
>
6901 <p
>Det mangler
16.000 ingeniører og IKT-fagfolk i Norge rapporterte
6902 arbeids- og velferdsetaten NAV. Linux-fagfolk kan velge svært
6903 interessante jobber med alt fra apps på ledende mobilsystem laget med
6904 Linux, sky- tjenester eller web-applikasjoner. De raskest voksende
6905 teknologiselskapene i verden er ute etter Linux-fagfolk. Det være seg
6906 Amazon, Google, Facebook og IBM for å nevne noen. Linux er kritisk
6907 for å sikre veksten i markedet. Det sier seg selv at lønningene og
6908 jobbmulighetene er bedre enn for andre tekniske yrker.
</p
>
6910 <p
>Skal man lage apps for mobilen, smart-TV-en eller
6911 underholdningssystemet i bilen eller på flyet, er det Linux som
6912 gjelder. Med en slik konkurranse om Linux-kompetansen, kombinert med
6913 motstanden mot Linux hos mange IT-sjefer i offentlig sektor, så
6914 hindrer kommunene rekruttering av flere Linux- fagfolk. Skolene blir
6915 tvunget til å velge dyrere og mindre komplette IT-system. De har
6916 blitt hengende igjen slik IT var på begynnelsen av
2000- tallet. Dette
6917 fordi IT-ledere ikke har tilpasset seg markedet det siste tiåret.
</p
>
6919 <p
>Når det er sagt, er Skolelinux svært enkelt å lære seg også for de
6920 som ikke kan. Det viser alle lærerne som drifter systemet for
6921 hundrevis og tusenvis av systemer. Det meste er på plass rett ut av
6922 boksen. I tillegg er det solid med dokumentasjon med god hjelp på
6923 nettet. Det er mange kommuner som har ansatt en lærer som først lærte
6924 Skolelinux på sin skole, for så å drifte alle PC-ene i kommunen med
6925 Skolelinux. Det kan fort være snakk om
1000-
3000 datamaskiner på
10-
15
6926 skoler som sentraldriftes med en stilling. Står man ordentlig fast,
6927 kan man også kjøpe profesjonell hjelp fra selskap som støtter
6928 Skolelinux. Det er flere slike selskap i Norge og i utlandet.

6932 <p
>Qt SDK, LibreOffice, Firefox, VLC og KDE-skrivebordet. Dette på et
6933 Debian-basert GNU/Linux-system. Jeg bruker også noen morsomme
6934 3D-spill. Idag kan jeg velge mellom over
30.000 Linux-programmer. Det
6935 finnes ikke tid i livet å undersøke alle valgmulighetene. Derfor er
6936 det bra med Skolelinux i skolen, da utvalget av programmer er
6937 begrenset til hva som er aktuelt i skolefagene.

><strong
>Hvilken strategi tror du er den rette å bruke for å få
6940 skoler til å ta i bruk fri programvare?
</strong

6942 <p
>Vi må selge hele Skolelinux forhåndsinstallert på maskinvare i hele
6943 pakker med
50-
100-
1000 PC-klienter med servere. Dette kan selges til
6944 enkeltskoler eller hele kommuner. Pakken må inneholde tjenermaskiner,
6945 svært rimelige diskløse arbeidsstasjoner, nettbrett med Plasma Active,
6946 og bærbare med roaming. Alt er godt testet med Debian. I et slikt
6947 anbud er det mulig å legge til sentraliserte drifts- og
6948 støttetjenester.
</p
>
6950 <p
>Man bør også selge sky-tjenester som læreadministrative systemet
6951 Moodle og driftsovervåking. I tillegg så bør man slenge seg på med
6952 presentasjoner de gangene LibreOffice og andre friprog-produkter
6953 selges til kommuner.

7030 gjennom studentprosjekter der elevene selv er med å utforme
7031 programvare direkte eller indirekte gjennom aktive bidrag. Dette gjør
7032 ikke bare samarbeidet tettere, men fokuset på standarder og friheten
7033 til å velge sin egen løsning vil kanskje stimulere interessen for
7034 framtidig deltakelse i bransjen. Vi som driver med fri og åpen

">Debian Edu / Skolelinux
</a

7047 ability for clients to automatically configure their proxy settings
7048 based on their environment. We want all systems on the client to use
7049 the WPAD based proxy definition fetched from
<tt
>http://wpad/wpad.dat
</tt
>, to
7050 allow sites to control the proxy setting from a central place and make
7051 sure clients do not have hard coded proxy settings. The schools can
7052 change the global proxy setting by editing
7053 <tt

> and the change propagate
7054 to all Debian Edu clients in the network.
</p

7056 <p

7079 <p
>To do this conversion I developed a perl script that will execute
7080 the javascript fragment in the WPAD file and return the proxy that
7082 <tt
><a href=
"http://www.debian.org/

>,
7083 and insert this extracted proxy URL in
<tt

7084 <tt

7085 fine in Squeeze, but in Wheezy the library it need to run the
7086 javascript code is
<a href=
"http://bugs.debian.org/
631045">no longer
7087 able to build
</a

7088 library. I hope someone find a solution to that problem before Wheezy
7089 is frozen. An alternative would be for us to rewrite wpad-extract to
7090 use some other javascript library currently working in Wheezy, but no
7091 known alternative is known at the moment.

7093 <p
>This automatic proxy system allow the roaming workstation (aka
7094 laptop) setup in Debian Edu/Squeeze to use the proxy when the laptop
7095 is connected to the backbone network in a Debian Edu setup, and to
7096 automatically use any proxy present and announced using the WPAD
7097 feature when it is connected to other networks. And if no proxy is
7098 announced, direct connections will be used instead.
</p
>
7100 <p
>Silently using a proxy announced on the network might be a privacy
7101 or security problem. But those controlling DHCP and DNS on a network
7102 could just as easily set up a transparent proxy, and force all HTTP
7103 and FTP connections to use a proxy anyway, so I consider that
7104 distinction to be academic. If you are afraid of using the wrong
7105 proxy, you should avoid connecting to the network in question in the
7106 first place. In Debian Edu, the proxy setup is updated using dhcp and
7107 ifupdown hooks, to make sure the configuration is updated every time
7108 the network setup changes.

7162 var noen annen løsning. «Vandrende arbeidsstasjon» mener jeg ikke
7163 fantes da. Dessuten ville jeg ha siste versjon, da den KDE-versjonen
7164 som var i Skolelinux den gangen var en god del enklere (tror det var
7165 KDE

7204 <description><p
>Since the Lenny version of
7205 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>, a
7206 feature to save power have been included. It is as simple as it is
7207 practical: Shut down unused clients at night, and turn them on again
7208 in the morning. This is done using the
7209 <a href=
"http://packages.qa.debian.org/s/shutdown-at-night.html
">shutdown-at-night
</a
> Debian package.
</p
>
7211 <p
>To enable this feature on a client, the machine need to be added to
7212 the netgroup shutdown-at-night-hosts. For Debian Edu, this is done in
7213 LDAP, and once this is in place, the machine in question will check
7214 every hour from
16:
00 until
06:
00 to see if the machine is unused, and
7215 shut it down if it is. If the hardware in question is supported by
7217 <a href=
"http://packages.qa.debian.org/n/nvram-wakeup.html
">nvram-wakeup
</a
>
7218 package, the BIOS is told to turn the machine back on around
07:
00 +-
7219 10 minutes. If this isn
't working, one can configure wake-on-lan to
7220 try to turn on the client. The wake-on-lan option is only documented
7221 and not enabled by default in Debian Edu.
</p
>
7223 <p
>It is important to not turn all machines on at once, as this can
7224 blow a fuse if several computers are connected to the same fuse like
7225 the common setup for a classroom. The nvram-wakeup method only work
7226 for machines with a functioning hardware/BIOS clock. I
've seen old
7227 machines where the BIOS battery were dead and the hardware clock were
7228 starting from
0 (or was it
1990?) every boot. If you have one of
7229 those, you have to turn on the computer manually.
</p
>
7231 <p
>The shutdown-at-night package is completely self contained, and can
7232 also be used outside the Debian Edu environment. For those without a
7233 central LDAP server with netgroups, one can instead touch the file
7234 <tt
>/etc/shutdown-at-night/shutdown-at-night
</tt
> to enable it.
7235 Perhaps you too can use it to save some power?

>I am happy to announce that finally we managed today to wrap up and
7245 publish the third beta version of
7246 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> based
7247 on Squeeze. If you want to test a LDAP backed Kerberos server with
7248 out of the box PXE configuration for running diskless machines and
7249 installing new machines, check it out. If you need a software
7250 solution for your school, check it out too. The full announcement is
7251 <a href=
"http://lists.debian.org/debian-edu-announce/
2012/
02/msg00000.html
">available
</a
>
7252 on the project announcement list.
</p
>
7254 <p
>I am very happy to report these changes and improvements since
7255 beta2 (there are more, see announcement for full list):
</p
>
7259 <li
>It is now possible to change the pre-configured IP subnet from
7260 10.0.0.0/
8 to something else by using the subnet-change tool after
7261 the installation.
</li
>
7263 <li
>Too full partitions are now automatically extended on the Main
7264 Server, based on the rules specified in /etc/fsautoresizetab.
</li
>
7266 <li
>The CUPS queues are now automatically flushed every night, and all
7267 disabled queues are restarted every hour. This should cut down on
7268 the amount of manual administration needed for printers.
</li
>
7270 <li
>The set of initial users have been changed. Now a personal user
7271 for the local system administrator is created during installation
7272 instead of the previously created localadmin and super-admin users,
7273 and this user is granted administrative privileges using group
7274 membership. This reduces the number of passwords one need to keep
7275 up to date on the system.
</li
>
7279 <p
>The new main server seem to work so well that I am testing it as my
7280 private DNS/LDAP/Kerberos/PXE/LTSP server at home. I will use it look
7281 for issues we could fix to polish Debian Edu even further before the
7282 final Squeeze release is published.
</p
>
7284 <p
>Next weekend the project organise a
7285 <a href=
"http://lists.debian.org/debian-edu-announce/
2012/
01/msg00001.html
">developer
7286 gathering
</a

7287 version, and start initial planning for the Wheezy version. Perhaps I
7288 will see you there?

7297 <description><p
>With some computer hardware, one need non-free firmware blobs.
7298 This is the sad fact of todays computers. In the next version of
7299 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> based
7300 on Squeeze, we provide several scripts and modifications to make
7301 firmware blobs easier to handle. The common use case I run into is a
7302 laptop with a wireless network card requiring non-free firmware to
7303 work, but there are other use cases as well.
</p
>
7305 <p
>First and foremost, Debian Edu provide ISO images for DVD and CD
7306 with all firmware packages in the Debian sections main and non-free
7307 included, to ensure debian-installer find and can install all of them
7308 during installation. This take care firmware for network devices used
7309 by the installer when installing from from local media. But for
7310 example multimedia devices are not activated in the installer and are
7311 not taken care of by this.
</p
>
7313 <p
>For non-network devices, we provide the script
7314 <tt
>/usr/share/debian-edu-config/tools/auto-addfirmware
</tt
> which
7315 search through the
<tt
>dmesg
</tt
> output for drivers requesting extra
7316 firmware. The firmware file name is looked up in the Contents-ARCH.gz
7317 file available in the package repository, and the packages providing
7318 the requested firmware file(s) is installed. I have proposed to do
7319 something similar in debian-installer (BTS report
7320 <a href=
"http://bugs.debian.org/
655507">#
655507</a
>), to allow PXE
7321 installs of Debian to handle firmware installation better. Run the
7322 script as root from the command line to fetch and install the needed
7323 firmware packages.
</p
>
7325 <p
>Debian Edu provide PXE installation of Debian out of the box, and
7326 because some machines need firmware to get their network cards
7327 working, the installation initrd some times need extra firmware
7328 included to be able to install at all. To fill the PXE installation
7329 initrd with extra firmware, the
7330 <tt
>/usr/share/debian-edu-config/tools/pxe-addfirmware
</tt
> script is
7331 provided. Again, just run it as root on the command line to fill the
7332 PXE initrd with firmware packages.
</p
>
7334 <p
>Last, some LTSP clients might also need firmware to get their
7335 network cards working. For this,
7336 <tt
>/usr/share/debian-edu-config/tools/ltsp-addfirmware
</tt
> is
7337 provided to update the LTSP initrd with firmware blobs. It is used
7338 the same way as the other firmware related tools.
</p
>
7340 <p
>At the moment, we do not run any of these during installation. We
7341 do not know if this is acceptable for the local administrator to use
7342 non-free software, and it is their choice.
</p
>
7344 <p

7361 språket melde seg til dyst. Det er mangel på nordsamiske oversettere
7362 av fri programvare. Hvis noen starter raskt, så bør en rekke å
7363 fullføre Wheezy-utgaven før den gis ut. :)

">Debian Edu

</a
> will include a new tool
7402 <tt
>sitesummary2ldapdhcp
</tt
>, which can be used to quickly set up all
7403 the computers in a school without much manual labour. Here is a short
7404 summary on how to use it to set up a new school.
</p
>
7406 <p
>First, install a combined Main Server and Thin Client Server as the
7407 central server in the network. Next, PXE boot all the client machines
7408 as thin clients and wait
5 minutes after the last client booted to
7409 allow the clients to report their existence to the central server. When
7410 this is done, log on to the central server and run
7411 <tt
>sitesummary2ldapdhcp -a
</tt
> in the
<tt
>konsole
</tt
> to use the
7412 collected information to generate system objects in LDAP. The output
7413 will look similar to this:

7427 <p
>After providing the LDAP administrative password (the same as the
7428 root password set during installation), the LDAP database will be
7429 populated with system objects for each PXE booted machine with
7430 automatically generated names. The final step to set up the school is
7431 then to log into
<a href=
"https://oss.gonicus.de/labs/gosa/
">GOsa
</a
>,
7432 the web based user, group and system administration system to change
7433 system names, add systems to the correct host groups and finally
7434 enable DHCP and DNS for the systems. All clients that should be used
7435 as diskless workstations should be added to the workstation-hosts
7436 group. After this is done, all computers can be booted again via PXE
7437 and get their assigned names and group based configuration
7438 automatically.

>I serien med intervjuer av folk i
7455 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet, har jeg nå
7456 lyktes med å få tak i en skolemann som ikke er aktiv med utviklingen,
7457 men likevel har vært med nesten siden starten av prosjektet. Jeg
7458 ønsker derfor velkommen til Paul Reidar Løsnesløkken, en mann med
7459 mange års erfaring i bruk av Skolelinux.
</p
>
7461 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
7463 <p
>Jeg driftet tidligere IKT løsningen for skolene i
7464 <a href=
"http://www.nord-odal.kommune.no/
">Nord-Odal
</a
>. I dag er jeg
7465 IKT-konsulent for hele kommunen og samarbeider med
7466 <a href=
"http://www.hedmarken-ikt.no/
">Hedmark-IKT
</a
> for best mulig
7467 tjenester til kommunen. Jeg har bakgrunn som elektronikkreparatør og
7468 grunnskolelærer og har tatt en del fag innen IKT, i hovedsak
7469 driftsfag. IKT i Nord-Odal kommune blir i dag driftet av Hedmark IKT
7470 som er et samarbeid mellom Løten, Stange, Grue, Hamar, Kongsvinger og
7471 Nord-Odal. Jeg er fortsatt
"IKT-personen
" på skolene i kommunen og
7472 følger opp og gjør enkelte mindre endringer der.
</p
>
7474 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
7476 <p
>Kommunen satset på Skolelinux i
2004. Jeg var ikke med i
7477 beslutningsprosessen den gang, men ble likevel med fra starten når
7478 dette ble levert.
</p
>
7480 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7482 <p
>Fordelene med Skolelinux er rask oppstart, sentral drift av
7483 klientene, klienter som jobber raskt og effektivt, bedre
7484 funksjonalitet på eldre utstyr og en ganske god programpakke med fri
7485 programvare som følger med. Løsningen med halvtykke klienter gjør at
7486 prosessering skjer lokalt med alltid ferske maskiner.
</p
>
7488 <p
>Skolelinux kan fungere godt på gammelt utstyr, men det er klart at
7489 utstyr også blir for gammelt selv for Skolelinux. I forbindelese med
7490 at vi nylig fikk nye servere og ny installasjon kastet jeg ut ca
60
7491 klienter som fortsatt var i drift etter at de var kjøpt godt brukt i
7492 2004. Noe var rundt
15 år gammelt, men var fortsatt i bruk. Noen
7493 klaget på at det nå gikk veldig tregt på en del pedagogiske nettsider
7494 med flash o.l. Det er fullt forståelig.
</p
>
7496 <p
>Jeg fikk nylig et spørsmål fra ungdomsskolens rektor om jeg kunne
7497 legge inn
<a href=
"http://freemind.sourceforge.net/
">FreeMind
</a
>, et
7498 tankekartprogram , på skolens elev-Windowsmaskiner. Lærerne hadde
7499 vært på kurs og ville ta dette i bruk. Skolen har ca halvparten av
7500 elevmaskinene på bærbare Windowsmaskiner. Da kunne jeg fortelle at
7501 dette programmet allerede lå inne på den nye Skolelinuxløsningen
7502 som nettopp var satt i drift, klart til bruk.
</p
>
7504 <p
>Vi har de bærbare maskinene på ungdomsskolen i domene med
7505 Skolelinux. Dette fungerer også meget bra nå. Elevene får opp en
7506 midlertidig windowsprofil når de logger på. Denne profilen slettes
7507 etter at de logger av, noe som medfører rene profiler hver gang de
7508 starter opp en maskin. De må lagre i sin Skolelinprofil, noe som
7509 medfører at de får tak i sine filer uavhengig av om de starter en
7510 Windowsmaskin eller en Skolelinuxklient. Det er mye mindre trafikk i
7511 det trådløse nettet etter at ikke hele profiler blir lastet opp til de
7512 enkelte Windowsmaskinene og tilbake når man avslutter. Jeg vet ikke om
7513 dette er standardoppsett i Skolelinux, men slik er vårt oppsett
7516 <p
>Vi har i flere år satt opp vår løsning slik at skriverkøer slettes
7517 og skrivere startes hver natt. Hyggelig å høre at dette nå skal bli
7518 en standard i Skolelinuxløsningen. Dette har vært en god hjelp for
7521 <p
>Elevene er lite opptatt av om de jobber på en Skolelinux eller en
7522 Windowsmaskin bare de har de programmene de trenger og at det virker
7523 når det skal brukes. Vi kjører mest mulig de samme programmene på
7524 Windows som i Skolelinux, som f.eks Audacity og LibreOffice.
</p
>
7526 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7528 <p
>Lærere bruker hos oss Windows. Dette fordi de da selv har mer
7529 kontroll over sin maskin, kan bruke den overalt, og kan legge inn
7530 programmer selv når de trenger noe i forhold til kurs o.l de er
7531 på. Jeg tror lærernes selvstendighet her gjør dem tryggere på IKT-bruk
7532 generelt. Det at de av og til får opp advarsler og lignende gjør også
7533 at de må tenke igjennom og spørre om ting rundt datasikkerhet.
</p
>
7535 <p
>Det er en del programmer vi bruker som ikke finnes for Linux. Mest
7536 brukt er nok Photostory3 som brukes i mange sammenhenger, særlig på
7537 ungdomsskolen, bl.a. til å lage herbarier (plantesamling) . Dette
7538 finnes gratis for Windows, men er ikke fri programvare. Vi er opptatt
7539 av at programmer elevene bruker på skolen også kan brukes gratis
7540 hjemme. Det er også en del programmer som brukes til spesielle elever
7541 som bare går i Windows. Det er viktig med fokus på funksjoner og ikke
7542 på hvilket OS man bruker.
</p
>
7544 <p
>For oss er det kombinasjonen mellom Skolelinux og Windows som gir
7545 oss en god og hel løsning. Skolelinux er best der de er gode.
</p
>
7547 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
7549 <p
>Selv er det LibreOffice jeg bruker til daglig. Jeg bruker selv en
7550 Windowsmaskin. Jeg har benyttet en del fri programvare i forbindelse
7551 med sjekking av trafikk i nettverk, slik som Wireshark, men dette er
7552 jo ikke aktuelt for skolene. Jeg er generelt glad i programmer som
7553 fungerer på både Linux og Windows og gjerne MAC.
</p
>
7555 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
7556 skoler til å ta i bruk fri programvare?
</strong
></p
>
7558 <p
>Det er viktig at det benyttes programmer som elevene også kan ta i
7559 bruk hjemme. Det skal da være enkelt, lovlig og gratis for
7560 elevene. Da er jeg ikke lenger veldig opptatt av om det kalles
"fri
7561 programvare
". For skolene tror jeg
"gratis
" og
"funksjonelt
" er bedre
7562 begreper enn
"fri
" i forhold til programmer. De fleste skiller nok
7563 ikke mellom
"fri
" og
"gratis
". Det er nå svært mange elever som
7564 benytter OpenOffice eller LibreOffice som sin primære kontorpakke

>During christmas, I have been working getting the next version of
7621 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> ready
7622 for release. The initial problem I looked at was particularly
7623 interesting.
</p
>
7625 <P
>The installer would hang at the end when it was doing it
7626 post-installation configuration, and whatevery I did to try to find
7627 the cause and fix it always worked while I tested it, but never when I
7628 integrated it into the installer and ran the installation from
7629 scratch. I would try to restart processes, close file descriptors,
7630 remove or create files, and the installer would always unblock and
7631 wrap up its tasks.
</p
>
7633 <p
>Eventually the cause was found. The kernel was simply running out
7634 of entropy, causing the Kerberos setup to hang waiting for more.
7635 Pressing keys was adding entropy to the kernel, and thus all my tries
7636 to fix the problem worked not because what I was typing to fix it, but
7637 because I was typing.
</P
>
7639 <p
>The fix I implemented was to add a background process looking at
7640 the level of entropy in the kernel (by checking
7641 /proc/sys/kernel/random/entropy_avail), and if it was too small, the
7642 installer will flush the kernel file buffers and do
'find /
' to
7643 generate some disk IO. Disk IO generate entropy in the kernel, and is
7644 one of the few things that can be initated from within the system to
7645 generate entropy.

7664 Denne gangen har jeg besøk av et avtroppende styremedlem i

</strong

7670 <p
>Jeg heter Peter Hansteen, og jobber til daglig som seniorkonsulent
7671 i EDB ErgoGroup i Bergen. I praksis betyr det systemadministrasjon på
7672 Unix (primært Solaris, men en viss komponent av Linux). Men Solaris
7673 er for meg et relativt nytt bekjentskap, hovedplattformen min har
7674 generelt vært OpenBSD og til dels FreeBSD.

7676 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
7678 <p
>Jeg husker ikke helt alle detaljene mer ;) - men jeg tror det var
7679 gjennom news-gruppen no.it.os.unix.linux.diverse, efn-listen og
7680 etterhvert også BLUG-miljøet her i Bergen. Vi hadde et par
7681 Skolelinux-sentrerte BLUG-møter for noen år siden, og det har vært et
7682 par Skolelinux-utviklersamlinger her.
</p
>
7684 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7686 <p
>Jeg bruker dessverre ikke Skolelinux daglig. Men slik jeg kjenner
7687 prosjektet har det vært i stand til å ta opp i seg det beste av fri
7688 programvare i mange kategorier, så fra et sysadmin-perspektiv ser det
7689 ut som en svært behagelig sak. For brukerne er det vel både en fordel
7690 og en ulempe at det ikke er Windows. Men vi håper at fordelene med et
7691 fritt system etterhvert vil bli åpenbare for både elever, lærekrefter
7692 og foreldre.
</p
>
7694 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7696 <p
>Vel, ulempen er vel først og fremst at andre aktører med mer
7697 kapitalmuskel har klart å etablere seg som det både lærere og foreldre
7698 føler seg trygge på, selv om det etter mitt hode ikke er noen grunn
7699 til å være spesielt trygg på de kommersielle alternativene.
</p
>
7701 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
7703 <p
>Når jeg får bestemme helt selv, bruker jeg kun fri programvare. Da
7704 helst med vekt på ting som kjører greit på OpenBSD. Hjemme er det
7705 OpenBSD, Ubuntu eller FreeBSD vi bruker. På skrivebordet er det en
7706 avveining mellom Gnome, KDE eller hva-det-nå-heter som er
7707 standardvalget i Ubuntu, ellers er det de kjente tingene som
7708 LibreOffice, Emacs, mplayer. På server er det selvfølgelig Apache,
7709 for overvåking både OpenNMS og Nagios (det bare ble sånn, og
7710 forskjellige siter). Jeg skriver til tider om slikt jeg holder på med
7712 <a href=
"http://bsdly.blogspot.com
">http://bsdly.blogspot.com
</a
>.
</p
>
7714 <p
>Men vi må nevne at selv vi har en Microsoft-ting som vi slår på når
7715 vi av en eller annen grunn må. Det betyr igjen vanligvis når en
7716 mobiltelefon eller en annen lukket elektronisk dings krever kontakt
7717 via en slik for å få oppdateringene sine.
</p
>
7719 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
7720 skoler til å ta i bruk fri programvare?
</strong
></p
>
7722 <p
>Hadde vi hatt det rette svaret på det spørsmålet, så hadde vi
7723 gjerne hatt Skolelinux som førstevalg på alle skoler ;)
</p
>
7725 <p
>Men jeg tror vi må legge vekt på flere forskjellige ting. En helt
7726 sentral sak er å fokusere på fri programvare og åpne standarder som de
7727 demokratiske verdiene de faktisk er. Det har kanskje kommet litt for
7728 mye i bakgrunnen i forhold til strevet etter å lage det mest mulig
7729 'brukervennlige
' systemet. Det er en tung vei å gå, så det er
7730 forståelig at freenix-aktivister heller velger å skrive kode og annet
7731 som er mer lystbetont. Mer praktisk tror jeg vi må gjøre i alle fall
7732 to ting: For det første sørge for å fortsette med å levere det best
7733 mulige frie produktet, slik at det er lett å både komme i gang og
7734 holde systemene i daglig drift, og for det andre
2) spore opp mulige
7735 aktivister der de finnes, via lokale brukergrupper, sosiale medier
7736 eller annet og sørge for at de fortsetter å være aktive. Mer og
7737 mindre uformelle treff kan være nyttig i tillegg til de mer
7738 organiserte møtene med foredrag, konferanser og utviklersamlinger.

7772 plattform. Dette vil si at man har en løsning som skal være mye
7773 tilgjengelig, og hvor det er relativt enkelt å få tak i personer som
7774 kan mye om den grunnleggende plattformen.

</strong

7778 <p
>De største utfordringene med en løsningen er at den er intensiv på f.eks
7779 nettverk. I seg selv ikke et problem for en enkelt skole, men skal løsningen
7780 kjøres i større skala, med sentraliserte servere, så gir dette noen
7781 utfordringer.
</p
>
7783 <p
>Utifra hva jeg har sett på større installasjoner så er det ikke så
7784 enkelt å skjønne, hva som bør gjøres for at den skal skaleres opp, og
7785 da ta godt vare på alle sider av dette, ikke bare mer server å fordele
7786 last/trykk, men hvordan også beholde robustheten og fleksibiliteten i
7787 løsningen.
</p
>
7789 <p
>En annen utfordring er at stadig flere produkter som skal brukes i
7790 skoleløsningen ikke er laget til å kunne brukes i en
7791 skolelinuxløsning. Det blir derfor fort mye skreddersøm i de
7792 forskjellige installasjonene, for å få diverse pedagogiske programmer,
7793 webløsninger, smartboards, m.m. til å fungere. Man er også en for
7794 liten kundebase til at leverandørene ønsker å gjøre noe med
7795 utfordringen. Problemet overlates til oss.
</p
>
7797 <p
>Det er også en kontinuerlig utfordring rundt problemet med å holde
7798 programvare på stabile versjoner, kontra å få ny funksjonalitet. Dette
7799 er jo en konflikt mellom oss som ønsker å drifte en stabil, og
7800 kostnadseffektiv løsning, mot sluttbrukerne som ønsker seg funksjoner
7801 det er vant med fra andre løsninger, eller som de må ha for at et
7802 eller annet nytt produkt skal fungere i løsningen. Dette er en
7803 utfordring også for andre plattformer.
</p
>
7805 <p
>En siste utfordring som ikke har noe med løsningen å gjøre, men med
7806 det omkringliggende miljøet denne skal kjøre i, er at de enhetene som
7807 skal drifte dataløsninger for kommuner og fylkeskommuner begynner å
7808 profesjonaliseres, og er da avhengig av å ha standard løsninger for å
7809 drifte store brukermasser. MS er selvsagt klar over dette, og har jo
7810 nå flere områder de begynner å bli veldig dominerende på. Den største,
7811 og mest problematiske er katalogtjenesten. Man får snart ikke tak i
7812 større løsninger som ikke krever en AD. Når man da har store enheter
7813 som drifter både kommunalt ansatte og skoler, så vil det være et
7814 stordriftargument å standardisere på en katalog tjeneste, og da har
7815 man ikke noe valg. Her er alle slike driftsenheter for små til å få
7816 gjort om på dette. Her burde konkurransemyndighetene kommet på
7817 banen. Men konkurransetilsynet i USA griper sjeldent (og ikke før det
7818 har gått veldig lang tid) inn i monopolsituasjoner så lenge
7819 monopolisten er et amerikansk firma, så da har vel ikke andre
7820 myndigheter så mye de skulle ha sagt....

><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
7824 <p
>Privat kjører jeg Debian på alle mine datamaskiner. Det gjør jeg
7825 også på min jobbmaskin. Vi har også
15-
20 linux servere av typene
7826 SuSE, Debian, Redhat, CentOS m.m. Jeg bruker derfor mye fri
7827 programvare. Av enkelt programmer kan sikkert masse nevnes. Hvis vi
7828 skal begrense oss til daglig, så må jeg si: OpenOffice, Firefox,
7829 Kontact, Kopete, Amarok,
7830 <a href=
"http://gramps-project.org/
">Gramps
</a
>, Kate, ssh, bash,
7831 rsync, backuppc m.m.
</p
>
7833 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
7834 skoler til å ta i bruk fri programvare?
</strong
></p
>
7836 <p
>Det er et godt spørsmål, som jeg har lurt på selv.
</p
>
7838 <p
>Argumentene som ofte har vært brukt om at ting koster mindre holder
7839 ikke mål når man ser på hva som faktisk koster penger. Det er de
7840 ansatte som er en kostnadsdriver. Det vil si at hvis man har et system
7841 som den ansatte kan, så vil en kostnad på dette systemet kunne
7842 forsvares ganske mye ved at den ansatte gjør dette raskere og
7843 effektivt. Også uten å måtte eventuelt leie inn folk.
</p
>
7845 <p
>Jeg syns det er viktigere å fokusere på prinsippet med å velge fri
7846 programvare, men det er også et felt hvor man fort møter lite
7847 forståelse blant de ansatte i skolen.
</p
>
7849 <p
>Her må nok strategien fortsette å være at de sentrale myndighetene
7850 må sende tydelige signaler for hva de ønsker at offentlige enheter
7851 skal gjøre. Det var mye positivt på gang ang. dette for et par år
7852 siden. Både med eNorge og eKommune planene, men dette syns jeg har
7853 stoppet opp. En del av dette kan jo kanskje være usikkerheten som
7854 etter hvert har blitt, når man har sett kompleksiteten i de
7855 prosjektene som har blitt igangsatt. Det har også blitt noe usikkerhet
7856 i markedet ref. Sun, Oracle, Novell, Microsoft m.m. Samtidig har jo
7857 også de proprietære programleverandørene sørget for å endre sine
7858 lisenser slik at man uansett ikke slipper unna kostnaden til deres
7859 produkter, selv om man skulle velge alternativer. Da er det økonomiske
7860 argumentet, som jeg nevnte tidligere, spilt ganske godt ut over
7861 sidelinjen.

7886 opp SPIST, Skolelinux-prosjektet i Sør-Trøndelag, hvor vi hjalp noen
7887 skoler i nærområdet med å installere Skolelinux og finne brukt
7888 IT-utstyr til disse. Det var moro å gjøre noe praktisk for å spre
7889 Skolelinux, og å se hvor fort gjort det var å sette opp utrangerte
7890 klientmaskiner og få disse opp som tynnklienter på helt nye datasaler
7891 på skolene, kun med kostnaden til servere.

7922 fleksibilitet, åpenhet og ikke låsing til en leverandør framfor sparte
7923 lisenskostnader, samt programvarens kvalitet og fortrinn, og at den
7924 fritt kan brukes på et ubegrenset antall PC-er, også hjemme hos
7925 elevene. En bør også forbedre den fri programvaren ved testing,
7926 bugrapportering og kodebidrag om man kan, og ikke anbefale programvare
7927 uten at man har forsikret seg at den har tilstrekkelig kvalitet,
7928 ellers kan man lett oppnå det motsatte. Tror en bør selge inn
7929 konseptet til fylkes-/statsnivå, kanskje med bidrag til
7930 utviklingsarbeid fra disse som alle landets skoler kan få glede

>Mine bloggposter om Linux i skolene i Norge førte til at inspektør
7941 og ildsjel på Harestad skole tok kontakt og fortalte at de bruker
7942 Linux på sin skole, og lurte på om de kunne bidra til å gjøre
7943 fordelene kjent. Riktig nok bruker de ikke
7944 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
> på denne skolen,
7945 men jeg synes dette er en god anledning til å gjøre flere fasetter
7946 rundt Linux-økosystemet kjent, og tok et lite intervju.
</p

7948 <p

7950 <p
>Mitt navn er Odin Hetland Nøsen og er en
70-modell. Jeg er bosatt i
7951 Stavanger og jobber nå på
9. året som undervisninginspektør på
7952 Harestad skole i Randaberg kommune (nabokommune til Stavanger).
</p

7954 <p
><strong

</strong
></p
>
7956 <p
>I
2002 begynte daværende IKT-ansvarlige og jeg et arbeid på skolen
7957 med å gå over fra Win98 til... noe annet. Vi testet en rekke
7958 forskjellige løsninger, deriblant Skolelinux, men endte opp med
7959 RedHat. Skolelinux var den gang ikke modent for det vi ville ha. Jeg
7960 har siden fulgt jevnlig med på hva skolelinux holder på med, men har
7961 hele tiden vært bedre fornøyd med vår egen
"standardiserte
" løsning på
7962 RedHat/CentOS og Fedora. Vi snuser for tiden på Ubuntu som løsning på
7963 klientsiden.
</p
>
7965 <p
>I dag har vi på skolen vår en større linux-løsning med
400 klienter
7966 som kjører en blanding av LTSP (tynnklient) og DRBL (tykk klient uten
7967 harddisk) med en masse tjenere på serverrommet. Vi drifter hele
7968 sulamitten selv med webtjener, eposttjener, webmail, filtjenere,
7969 virtuelle tjenere osv. Og IT-ansvarlig har en
80% stilling som
7970 IT-ansvarlig - og så er han KoH-lærer i de resterende
20% :-)
</p
>
7972 <p
>Du kan få en ide om hva vi holder på med om du går inn på
7973 <a href=
"http://www.gnuskole.no/
">http://www.gnuskole.no/
</a
>.
</p
>
7975 <p
>For å ta brodden av frykten for at ildsjeler gjør skolen sårbar om
7976 ildsjelene falle fra, har jeg forsikret kommunen og skolesjefen i
7977 Randaberg om at det finnes godt kommersielle tjenester vi kan benytte
7978 oss av - om det skulle bli nødvendig. Vi er tre stykker i kommunen som
7979 nå har
<strong
>god
</strong
> linux-kompetanse ift. å drifte et større
7980 system. IT-avdelingen i kommunen vil ikke ta på oss med ildtang -
7981 selv om vi nok har større IT-kompetanse mot linux enn det de selv har
7982 mot windows (de kjøper en
<strong
>masse
</strong
> konsulenttjenester
7983 fra ErgoGroup).
</p
>
7985 <p
>I kvantitet er Harestad og Grødem skole tilsammen et større
7986 IT-system enn resten av Randaberg kommune + Kvitsøy og Rennesøy, som
7987 kommunen også har driftsansvar for. Vi har som sagt rundt
800
7988 maskiner, mens kommunen med sitt driftsansvar har ansvar for rundt
500
7989 maskiner. Det er selvfølgelig litt forskjell i hvor kritiske
7990 tjenestene våre er, men det gir allikevel et litt rart bilde når
7991 IT-avdelingen overhode ikke er interessert i å snakke med oss om
7992 hvordan vi gjør ting :-)
</p

7994 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7996 <p
>Fra linux-perspektivet (ikke bare Skolelinux) er det en fordel av
7997 systemet er basert på fri programvare - og dermed fritt i ordets mange
7998 betydninger. Det er alt vi trenger: stabilt, relativt enkelt å drifte
7999 (tross alt - et større windowssystem er ikke enkelt å holde live det
8000 heller), rimelig i innkjøp og drift, og sist, men ikke minst, det er
8001 moderne for sluttbruker! Linux, i sine mange varianter,
8002 <strong
>ser
</strong
> nytt ut, fordi det hele tiden blir
8003 oppdatert. Derfor lever systemet opp til hvordan elever forventer at
8004 et moderne GUI skal være (i motsetning til WinXP :-).
</p
>
8006 <p
>Vi var veldig pragmatiske da vi begynte med linux i skolen. Det var
8007 billig, det fungerte og kunne bruke alle de gamle windows-maskinene
8008 som
"nye
" tynne klienter. I dag er vi mer bevisste fri
8009 programvare-tilhengere. Vi har oppdaget hva det er - og vi liker
8012 <p
>En av de
<strong
>store
</strong
> fordelene med fri programvare er at
8013 vi kan installere tjenester vi ønsker å tilby brukerne våre - uten å
8014 måtte tenke på om vi har råd til lisensene (fordi det er ingen). Alt
8015 vi setter i produksjon er ut i fra brukernes behov og vår kapasitet
8016 til å drifte dem. Vi skreddersyr tjenestene etter behovet og dermed
8017 trenger vi ikke ende opp med å kjøpe en pakke der vi egentlig bare var
8018 interessert i en liten del av den.
</p
>
8020 <p
>Bruk av linux frigjør ikke økonomiske midler, fordi midlene til IKT
8021 i skole er for få i utgangspunktet - men vi får så
8022 <strong
>mye
</strong
> mer igjen for dem når vi bruker en linux-løsning
8023 fremfor en windows-løsning. I praksis ser vi at vi måtte ut med det
8024 dobbelte på budsjettet vårt om vi skulle hatt en tilsvarende
8025 windows-løsning, som det vi i dag drifter med linux.

8027 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
8029 <p
>Ikke all pedagogisk programvare er tilgjengelig. Det er en del
8030 programvare i skolen som er laget med utviklerverktøy som bare virker
8031 i windows, f.eks. Drillpro, LingDys/LingWrite. Det er også
8032 "programmer
" som bare virker om du har tilgang til Microsoft Office,
8033 f.eks. AskiRaski.
</p
>
8035 <p
>Vi sliter også litt med at video-codecer ikke alltid er like lett å
8036 få opp å gå på klientene. Det er alltid en eller annen videosnutt fra
8037 nrk.no som ikke er så samarbeidsvillig, uansett mediaplayer.

8039 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong

8041 <p
>Alt :-) På skolen bruker vi det som finnes og som er nyttig. Det vi
8042 bruker mest er Firefox (jobber med Chrome, fordi det er
8043 <strong
>mye
</strong

8044 over til LibreOffice), GIMP osv. Standardpakken av
8045 sluttbrukerprogrammer.
</p

8047 <p
>På tjenernivå bruker vi OpenWebMail (skal over til Zimbra), Exim
8050 <p

8055 skoler til å ta i bruk fri programvare?
</strong

8057 <p
>Jeg er langt i fra sikker. For det første handler det mye om at
8058 IKT-avdelingen i kommunen ofte er de som styrer hva som er IKT på
8059 skolene - og de liker å bruke avtalene med Microsoft, som de garantert
8060 har fra før. Dessuten - Select
6-avtalen til skolene gjør Microsoft
8061 skvettbillig.
</p
>
8063 <p
>Vi la vekt på effektiv drift av systemet - og at vi kunne øke
8064 antall maskiner uten å måtte øke budsjett for utstyr eller personell
8065 særlig mye, enn om vi hadde gått for en Microsoft-løsning. I praksis
8066 ser vi at en ren linux-installasjon driftes til halve prisen av en
8067 Microsoft-løsning.
</p
>
8069 <p
>Vi har i praksis også sett at det lærerne (og elevene) liker er at
8070 vi tilbyr
<strong

</strong

8071 vanlige i en Microsoft-løsning. Det er ikke så vanlig at
8072 <strong

</strong

8073 også brukt som et vellykket argument mot Microsoft.
</p

8075 <p

8076 det. Problemet er å få dem som har makt til å bestemme det til faktisk

8161 flinke folk. Denne gangen har jeg fått et ferskt styremedlem som
8162 kommer fra Ubuntu-miljøet i tale.

8166 <p
>Rubén Romero y Cordero,
81-modell, deltidspappa (
50%) for en jente
8167 på
6 år. Jobber i Oslo som Global Sales Executive hos Varnish Software
8168 og til daglig har jeg kontakt med kunder fra hele verden. Min
8169 forkjærlighet for fri programvare har gjort at jeg har nå flere års
8170 erfaring med salg av slike løsninger (bl.a. fra Redpill Linpro og
8171 Freecode) og mye innsikt og kunnskap om det globale IT-markedet.
8172 Ellers er jeg involvert i flere prosjekter bl.a. er jeg Ubuntu
8173 Community medlem, kontaktpersonen for Ubuntu Norge og driveren av
8174 SpreadUbuntu marketing prosjektet og nå fersk styremedlem i FRISK. Jeg
8175 har brukt GNU/Linux siden
1997.

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

8179 <p
>Som Debian bruker siden slutten av
90-tallet var det uunngåelig å
8180 ikke komme bort i Skolelinux. Dette var vel i slutten av
2001 når jeg
8181 var student ved UiO. Flere år senere fikk jeg lastet og testet Venus
8182 (Skolelinux
1.0) på release dagen.

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

8186 <p
>Fri programvare bygges sten for sten i det åpne, slik at koden og
8187 prosessen den lages på kan gjennomskues av andre enn de som har laget
8188 det. Det er et vitenskapelig og gjennomsiktig måte å lage programvare
8191 <p
>Skoler i vårt samfunn skal være steder hvor vitenskapelig kunnskap
8192 deles til alle. I dag har vi ikke et vitenskapelig tilnærming til
8193 hvordan programvaren som brukes på skolen lages. Skolelinux bringer
8194 inn at slik tilnærming i skoleverkets klasserom, siden
8195 operativsystemet er en åpent platform som gir skolene muligheten til å
8196 dra nytte av programvare som er laget av tusenvis av mennesker verden
8197 rundt og som gir elevene så vel som lærerne muligheten til å bruke,
8198 dele, forandre og forbedre OSet sitt uten begrensninger. I den
8199 forbindelsen representerer Skolelinux også konkrete resultater utfra
8200 samhandling på tvers av grenser.
</p
>
8202 <p
>Når det gjelder de tekniske fordelene av Skolelinux er jeg sikker
8203 på at andre enn meg har allerede beskrevet disse bedre enn det jeg
8204 kan. Men jeg kan likevel tilføye noe: Skolelinux som sådan er en
8205 community-drevet operativsystemplatform. Som i ethvert
8206 community-prosjekt har alle Skolelinux brukere muligheten til å
8207 påvirke retning av prosjektet og resultatet som gjenspeiles i
8208 programvaren. Dette kommer sjeldent frem og jeg mener at det er noe
8209 som burde fokuseres mer på.
</p
>
8211 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
8213 <p
>De største ulempene er:
</p
>
8216 <li
>Mangel på kompetanse
</li
>
8217 <li
>Mangel av administrative verktøy som kunne hjelpe lokale IT
8218 avdelinger å bruke Skolelinux til mer enn bare en tjener for
8219 terminalklienter. Et eksempel: Zentyal sin web-dashboard.
</li
>
8222 <p
>Bedre og mer intuitive administrative verktøy kunne løst deler av
8223 problemet, men det er unektelig at ved bruk av Skolelinux må
8224 IT-personalet vite hva de gjør for å få ting gjort riktig, eller i det
8225 hele tatt. Med andre platformer er kompetansen enklere tilgjengelig og
8226 løsningene kan fungere på en tilfredstillende, om ikke riktig
8229 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong

8231 <p
>Har brukt GNU/Linux utelukkende sommitt skrivebord OS siden
2000. I
8232 dag bruker jeg Ubuntu og gjør det meste med friprogramvare verktøyene
8233 som er tilgjengelige der. Med over
20.000 programmer å velge mellom er
8234 dette mer enn nok for de fleste brukerne.

8236 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
8237 skoler til å ta i bruk fri programvare?
</strong

8239 <p
>Opplysning og pragmatikk. Vi prøver å løse problemer med bruk av
8240 programvare. De fleste utfordringene skolene har på IKT-siden kan
8241 løses ved hjelp av friprogramvareverktøy i dag. Det som trenges er
8242 opplysning, kunnskap og kompetanse.

8263 Vi ser på en åpen løsning som integrerer eksisterende lukkete
8264 løsninger sammen med fri programvare. Målet er å gi elever og lærere
8265 en plattform som de kan tilpasse utfra behov.
</p

8267 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
8269 <p
>Skolelinux har jeg møtt ved flere anledninger opp gjennom åra, både gjennom
8270 entusiastiske skolelinuxbrukere og skeptiske
"forståsegpåere
" :-)
</p
>
8272 <p
>Jeg husker en leverandør av et stort OS for noen år siden mente at
8273 Skolelinux var kun for hackere og nerder og at ingen seriøse skoler
8274 kunne ta dette i bruk. Heldigvis er kunnskapen større nå og
8275 skikkelige
"IT-folk
" søker alltid å utvide sin kunnskap.
8277 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
8279 <p
>Ja det er mange fordeler. Uavhengighet, stabilitet, åpenhet, standarder
8280 osv. Tror det er viktig at man ikke begrenser mulighetene på den plattformen
8281 elevene skal jobbe.
</p
>
8283 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
8285 <p
>Det største hinderet er det vi opplever på andre områder rundt
8286 fri programvare, nemlig kunnskap. For mange er det trygt å velge det vi
8287 alltid har valgt. Fordi leverandørene rundt oss sitter på den kunnskapen og
8288 de vi støtter oss på har den samme. Hvis vi klarer å riste løs litt og
8289 glemme gamle kriger mellom operativsystemer og leverandører, men sette ned
8290 hva som er viktig og velge ut fra det, så hadde man kanskje kommet ut med
8291 litt andre resultat. Jeg tror IT-folk er konservative og velger tradisjonelt
8292 og det er synd.
</p
>
8294 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
8296 <p
>Jeg bruker Ubuntu, Android, Jolicloud, Open Office, Zimbra, Picasa
8297 og Firefox samt en bråte med tjenester som er webbasert. Det eneste
8298 som er betalingslisens for er OSX. Ser at jeg jobber mer og mer i
8299 skyen og setter pris på alt jeg slipper egen klient til. Derfor er
8300 jeg veldig sjarmert av små kjappe operativsystemer som krever minimalt
8301 av maskinvaren.

>
8303 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
8304 skoler til å ta i bruk fri programvare?
</strong
></p
>
8306 <p
>Tror en blanding av krav og informasjon er veien å gå. Krav om
8307 sikkerhet, oppetid og åpne standarder. Informasjon om muligheter og
8308 alternativer. Her har leverandører, IT-avdelinger og pedagoger en vei
8309 å gå sammen. Det er til slutt LÆRING det dreier seg om, og da må man
8310 få mest mulig læring for pengene man har.

8327 <p
>Sturle Sunde, ansvarleg for skulenettet i Flora kommune. Eg driv,
8328 vidareutviklar og er andrelinje brukarstøtte for datanettet ved
8329 skulane i Flora kommune.
10 skular og meir enn
700 maskiner med
8330 Linux, medrekna tynnklientar. Tidlegare jobba eg i mange år med
8331 unix-drift ved Universitetets senter for informasjonsteknologi ved
8332 Universitetet i Oslo.
</p
>
8334 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
8336 <p
>Det er vanskeleg å svare konkret på. Eg har drive med Unix og Linux i
8337 alle år, og Skulelinux er eit godt kjent prosjekt i miljøet. Det var
8338 først i
2008, då eg tok til i min noverande jobb, at eg fekk bruk for
8339 Skulelinux for alvor.
</p
>
8341 <p
>Jobben min skulle vere drift av eit nytt skulenett i Flora kommune,
8342 levert av eit firma eg ikkje vil reklamere for. Systemet skulle vere
8343 ferdig levert i september året før. Dette viste seg å ta mykje lenger
8344 tid, og i haustferien
2008 hadde dei endå ikkje klart å få opp ei
8345 fungerande løysing. Situasjonen var prekær for den største skulen i
8346 kommunen med meir enn
500 elevar på ungdomssteget. Skulen hadde brukt
8347 Skulelinux før, og var tilfredse med det. No hadde dei vore utan
8348 fungerande datasystem i nesten eit år. Difor fekk eg opp ein ny tenar
8349 utanfor prosjektet og installerte Skulelinux på den. Etter litt
8350 justering av konfigurasjonen med god hjelp av #skolelinux på IRC, var
8351 den nye tenaren oppe og gjekk med både tynne og halv-tjukke klientar.
8352 Autentisering gjekk mot det nye systemet, slik at elevar og lærarar
8353 framleis har same brukarnamn og passord over alt. Dette berre
8354 fungerte, og vi bestemte oss for å erstatte delar av løysinga vi
8355 skulle få levert med Skulelinux.
</p
>
8357 <p
>Det høyrer med til historia at det nye systemet eg skulle drive frå
8358 januar
2008 endå ikkje er ferdig levert. Dei jobbar med saka, seier
8359 dei, og har von om å fullføre leveransen i løpet av
2011.
</p
>
8361 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
8363 <p
>Det er veldig mange. Eg skal ta nokre få.
</p
>
8365 <p
>Den viktigaste fordelen er at det igrunn berre er ei maskin å passe
8366 på, og det er tenaren. Med andre løysingar har ein gjerne programvare
8367 og anna som skal vedlikehaldast på kvar enkelt maskin. Med Skulelinux
8368 kan alle feil rettast og alle program oppgraderast på alle maskiner
8369 samstundes ved å gjere endringa som må til på tenaren. Eg kan sitje
8370 på kontoret og passe på alle tenarane i kommunen derifrå.
</p
>
8374 <li
>Tynne klientar gjer det mogleg å bruke eldre utstyr lenge, so lenge
8375 tenaren er sterk nok. Ein liten tenar med eit par halv-moderne CPUar
8376 og
2 GiB RAM held lenge for eit typisk klasserom med
30 tynnklientar,
8377 og det er lett å utvide med fleire.
8379 <li
>Halvtjukke klientar gjer det mogleg å utnytte kapasiteten i litt
8380 nyare maskiner betre, og avlaste tenaren. Ingenting vert installert
8381 lokalt på desse heller, og harddisken kan gjerne koblast frå. Gode
8382 halvtjukke klientar kan kjøpast brukt for under
1000-lappen, og det er
8383 heile kostnaden. Ingen lisensar eller anna på toppen, og det er ikkje
8384 krav til kraftigare tenar heller.
8386 <li
>Det er Linux. Vi har ikkje noko kluss med drivarar, dei berre er
8387 der. Heller ikkje med virus, dei finst i realiteten ikkje. Eller med
8388 elevar som klussar med installert programvare, for dei klarar ikkje å
8389 øydeleggje for nokon andre enn seg sjølve.
8393 <p
>Skulelinux er lagt opp til å vere veldig lett å installere rett ut
8394 av boksen på ein heil skule av ein interessert lærar. Det er ofte ei
8395 god løysing for skulen. Å ha nokon til stades som kjenner systemet og
8396 kan forklare enkle ting eller løyse problem der og då, er uvurderleg
8397 viktig for ein stressa lærar fem minutt før det ringer inn.
</p
>
8399 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
8401 <p
>All den ferdige konfigurasjonen gjer det tungvint å tilpasse
8402 Skulelinux til eit system som skal fungere saman med mange andre
8403 installasjonar i eit felles datanett for skulane i ein kommune. Det
8404 heile er prekonfigurert for ein skule, og utviding til mange skular
8405 med eigne tenarar er ikkje berre enkelt.

8407 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
8409 <p
>Eg brukar mest alle små hjelpeprogram som føl med operativsystemet,
8410 samt scriptspråket perl. Elles er Firefox/Iceweasel, Gnome-terminal
8411 og ssh i kontinuerleg bruk. Av Linux-distribusjonar brukar eg både
8412 Debian, Ubuntu, SuSE og RedHat dagleg. Eg prøvar å finne det verktyet
8413 som passar best til kvar del av jobben.

8416 skoler til å ta i bruk fri programvare?
</strong

8418 <p
>Det er to målgrupper ein må sikte mot. Det eine er alle skulane som
8419 manglar eller har eit lite tilfredsstillande opplegg i dag, og ikkje
8420 har råd til å kjøpe noko nytt og blankpussa opplegg. Der er det om å
8421 gjere å gjere det enkelt for skulane å finne Skulelinux, og gjere det
8422 enkelt for dei å få hjelp til installasjon på skulen. Gjerne med
8423 lokale kontaktpersonar. Her er det dugnadsinnsats som må til, for
8424 desse skulane har ikkje råd til å betale for dette.
</p
>
8426 <p
>Den andre og kanskje viktigare målgruppa er dei meir eller mindre
8427 profesjonelle kundane. Alle store offentlege innkjøp, inkludert
8428 innkjøp av nytt datasystem for skular, må ut på offentleg anbod.
8429 Offentlege anbod er mykje meir lukka enn dei gjev inntrykk av, og både
8430 regelboka og boka med triks for å sminke tilbodet er tjukk. Det er
8431 vanskeleg å komme inn utan eit solid salsapparat i ryggen. Kanskje
8432 Skulelinux skulle prøve aktivt å få seg eit partnarskap med eit av dei
8433 store som gjerne vil sterkare inn på den offentlege IT-marknaden?
8434 Nokon som kjenner triksa og har krefter til å ta opp kampen mot både
8435 dårlege anbod og Rudolf Blostrupmoen IT AS. Leveranse til skulane i
8436 ein kommune er ein god måte å få ein fot inn døra som leverandør til
8437 ein lukrativ kommunemarknad som kjøper alle tenester. Ta kontakt med
8438 nokon som er passeleg store og ikkje er Microsoft-partnar, og fortell:
8439 «Vi har eit ferdig produkt som du kan selje. Nei vi skal ikkje ha for
8440 det. Du kan gjerne gjere kva du vil med det, berre vi får lov til å
8441 hjelpe deg. Målgruppa er alle kommunar, og det er noko dei vil ha.
8442 Det er eit godt produkt, brukt av mange og godt likt.»

8468 <p
>Jeg leste en artikkel om en dugnadsinstallasjon av Skolelinux på en
8469 skole på Jæren et sted. Tanken om dugnad og frihet appellerte til
8470 meg. Da vi skulle bygge ny skole var det en del vi måtte spare på,
8471 fordi vi beveget oss mot en kostnadssprekk. Kabling og investering i
8472 PC-er var en av tingene vi sparte på. Derfor kjøpe vi
72 pc-er for
390
8473 pr stk. En filtjener og en applikasjonsserver.

8477 <p
>Fordelen er at så mye er satt opp fra starten. I tillegg er det
8478 tydelig at pakka er laga for skoleverket. Brukerne har egne
8479 skrivebord, tilgang på mange gode verktøyprogrammer. Vi slipper å
8480 tenke på virus. Brukerne har ikke mulighet til å ødelegge
8481 klientoppsett, men har gode muligheter til å endre eget oppsett. Dette
8482 tror jeg er inspirerende og kjekt for mange brukere. Mappestrukturen
8483 er ferdig og det er
"enkelt
" å designe lokale mappestrukturer via
8484 skeleton. Noen av oss i skoleverket mener skolen skal være en
8485 "mot-kultur
". Da er Skolelinux et av valgene man kan ta. Et annet er å
8486 spise på indisk restaurant i stedet for Mc Donald
's når vi er på bytur
8487 osv.. Ordene deling, frihet, dugnad osv er positive ord i
8488 skoleverket. Det er viktig at elevene blir bevisst dette.

</strong
></p

8492 <p
>Kompabiliteten er selvsagt et problem, selv om det er mindre nå enn
8493 før. For IKT-personer på skolene som skal drifte dette er det
8494 problematisk med kommandoer i terminalen. I tillegg er det alt for
8495 mange programmer i Skolelinux som ikke blir brukt. Jeg tror
8496 Skolelinux er tjent med å tone ned begrepet pedagogisk programvare.
8497 Slik jeg ser det finnes ikke denne kategorien programmer lengre slik
8498 de gjorde før, som frittsående programmer som installeres på en
8499 datamaskin eller på serveren. Det finnes en del spesialpedagogiske
8500 programmer, som Textpilot, LingDys, LingRight, AskiRaski, Ny i Norge
8501 osv. Men dette er programmer for enkelt-elever eller små grupper av
8502 elever. Det som bør være fokus er at alle undervisningsressurser som
8503 lages for nettet skal være nettleseruavhengig.

8507 <p
>OpenOffice bruker jeg til vanlig kontorarbeide. VLC bruker jeg som
8508 videoavspiller og av og til streaming av film. Gimp bruker jeg i
8509 undervisningen til bildemanipulering. Firefox og Chrome er mine
8510 favoritt-nettlesere. Firefox har lenge vært førstevalget mitt, nå
8511 bruker jeg mest Chrome. Opplever den som raskere og smidigere enn
8512 Firefox. Ubuntu bruker jeg som dualboot på jobb-maskinen min i
8513 tillegg til at alle PCer hjemme har en eller annen Ubuntu-distribusjon
8514 installert. Jeg bruker Clonezilla på Ubuntu
10.04 til kloning av
8515 datamaskiner på jobb. Det er selvsagt en haug andre frie programmer
8516 jeg bruker men jeg bruker dem ikke daglig. Jeg kan ramse opp:
8517 recordmydesktop, cinelerra, acidrip, soundjuicer, audacity, NX
8518 (no-machine), Kino, Rythmbox...

>Jeg tror oppsøkende virksomhet er den rette strategien.
8524 Ressurspersoner gjør avtaler med rådmenn, skolesjefer, rektorer. Det
8525 er slik konkurrentene gjør det. Fokuset i slike samtaler bør være
8526 kost-nytte. Dersom personer med økonomisk ansvar ser at de kan få
8527 like godt tilbud til mindre utgifter, tror jeg det er mulighet til å
8528 få innpass. Dersom de også kan få konkrete tilbud på drift i slike
8529 samtaler, vil de kanskje bli litt mer interesserte i hvor mye penger
8530 som faktisk går til IKT i skolene. Det er også viktig at vi ikke
8531 firer for mye på krav til datamaskiner. Det er flott at Skolelinux
8532 går på
"utrangert
" utstyr, men dette bør bare presenteres som et
8533 alternativ. Skolelinux-installasjoner med utrangert utstyr er ikke å
8534 foretrekke dersom man kan unngå det. Det skaper ikke entusiasme hos
8535 brukerne (elever og lærere) når de bruker gamle datamaskiner som går
8536 tregt. Det er kjempefint med skoler som har kommet seg frem til
8537 Skolelinux og fri programvare av seg selv, men de lever på nåde.
8538 Slike valg må fundamenteres hos skoleeier.

8572 <p
>Det startet i
2002 ved at jeg installerte en av de første utgavene
8573 av Skolelinux på en standard pc på Solneset skole i Tromsø. Denne var
8574 oppe fram til desember
2003 da jeg sluttet på den skolen og begynte i

2004 kun
2 servere på da totalt
15
8578 skoler. Disse var Windows NT baserte. På disse to skolene var det lite
8579 med maskiner. Jobben med å få Narvik Kommune opp på akseptabelt nivå
8580 virket å være formidabel. Men med hjelp av gode kollegaer og leder
8581 skrev jeg en IKT plan for Narvik kommune som ble vedtatt av politikere
8582 i august
2004. I denne planen ble det bestemt at Narvik kommune skulle
8583 bruke Skolelinux. Her ble det også satt av midler til kabling av god
8584 infrastruktur på alle skoler samt innkjøp av nye datamaskiner. Så i
8585 dag har vi
17 servere hvorav
13 er på Skolelinux, med ca
1500 klienter

8669 men det virker ut som det ikke skjer noe mer på. I tillegg var vi med

>Kommunen min har to omtrent jevnstore tettsteder, og en
8722 ungdomsskole i hvert av tettstedene. Den minste av disse har ca
300
8723 elever og til denne sogner det
3 barneskoler. Den største har ca
350
8724 elever og til denne sogner det
4 barneskoler.
</p
>
8728 <li
>Kommunen har i veldig lang tid forsømt IKT i skolen, og det har
8729 bare blitt gitt smuler i ny og ne. Det er kun den største av
8730 ungdomsskolene som har hatt en skikkelig datapark, og dette takket
8731 være en naturfaglærer som ble lei av å vente på kommunen. Det gjorde
8732 at vi bestemte oss for å ta ting i egne hender, og da vha
8733 skolelinux. En testinstallasjon med
10 gamle PCer ble gjort, og vi så
8734 raskt at dette var veldig lovende. Neste etappe var å gi alle lærere
8735 egen PC på arbeidsplassene sine (
2004), og så sette opp
16 PCer på to
8736 datarom. Vi har kun basert oss på å kjøpe inn brukte maskiner, og
8737 aldri dyrere enn
1000 kr pr klient. For to år siden så hadde vi
8738 klienter i alle klasserom, og totalt hadde vi da rundt
250 stk. Rundt
8739 40 klienter brukes av lærerne og kjører på en egen server. Elvene har
8740 resten, og kjører også en egen server. Servere har vi også kjøpt
8741 brukt,
2 år gamle servere koster
6-
7000 kroner.
</li
>
8743 <li
>Skolen vår er et relativt gammelt bygg, men en meget dyktig
8744 vaktmester har sammen med IKT-ansvarlig/Naturfaglærer lagt kabler til alle
8745 rom. Gradvis har vi byttet ut billige svitsjer med mer solide saker
8746 som er mulig å fjernstyre.
</li
>
8748 <li
>Vi har i all hovedsak greid å få dette til over eget budsjett, men
8749 vi har også passet på å få penger når de andre skolene har fått
8750 bærbare PCer til lærere osv.
</li

8752 <li
>Vår IKT-ansvarlig har gjort (og gjør) en fenomenal jobb, og vi har
8753 en maskinpark som de andre av kommunens skoler bare kan drømme
8758 <p
>Så skjer det som ofte skjer. Det kommer en eller annen
8759 selger/blåruss og skal fikse ALT. I vårt tilfelle betyr dette også
8760 sentralisering av drift. Den ny-ansatte på kommunens IT-avdelingen
8761 skal også ha jobb, og ser for seg å ta over skoledriften. Kommunen
8762 kjøper inn eksterne driftstjenester, og nekter i samme slengen å ta
8763 hensyn til skolen vår. Dette til tross for at vi alene har like mange
8764 datamaskiner som de andre til sammen.
</p
>
8768 <li
>Det blir krevd at vi skal innlemmes i de kommunale systemet, og
8769 det er VI som får ansvar for at dette kommer på plass. Og det er her
8770 de horrible tingene begynner å skje.

8773 hente epost for våre ansatte. Og det kreves at vi finner løsning på

8777 at vi må bruke en terminalløsning mot kommunal server. Ikke i seg selv
8778 et problem i følge IKT-ansvarlig hos oss. Men kommunens IT-avd nektet
8779 faktisk å åpne de porter OSV som vi måtte bruke.
</li
>
8781 <li
>Vi blir pålagt å flytte på innsiden av det kommunale
8782 nettverket. Dette gjorde at vi mistet hjemmekontor for lærere og
8783 elever. Å få åpnet porter i kommunal brannmur var ikke
8784 aktuelt. Mulighet for fjerndrift ble også vekk i samme slengen.
</li
>
8786 <li
>Vår LMS Moodle er ikke mulig å nå for elevene og lærerne.
8790 <p
>Den andre ungdomsskolen i kommunen begynner så å kreve at de skal
8791 få bedre datatetthet, og komme opp på et nivå som ligner det vi
8792 har. De ser at vi kan avholde eksamen hvor alle
10. klassingene får
8793 sitte ved hver sin PC. Og de har fått tilbakemelding (klager) fra VGS
8794 om manglende datakompetanse på elevene som kommer fra dem. Dette fører
8795 videre til at kommunen endelig innser at de må ta grep.
</p
>
8797 <p
>Grepet betyr sentralisering, og farvel til vår plattform får vi
8798 høre. Det blir gjort en rekke bestemmelser og vedtak som vi ikke får
8799 være en del av. Det blir helt klart at vi må redusere antall maskiner,
8800 og det skal satses på bærbare maskiner. Siden vi ikke har fått tatt
8801 del i prosessene som angår oss, så bruker vi fagforening. Vi har ikke
8802 blitt hørt i forbindelse med endringer som er betydelig for vår
8803 hverdag, og greier å stoppe omlegging. I tillegg så har vi et politisk
8804 vedtak i kommunen på at vi skal kjøre Linux på elevnett, og dette
8805 vedtaket kan ikke administrasjonen i kommunene helt uten videre
8806 tilsidesette.

8808 <p

8810 systematisk motarbeidet.

8883 flere brudd på anbudsregler, og vi kjenner til at relativt store
8884 IT-leverandører som ikke har fått tatt del i disse anbudene, rett og

8894 første timen på jobb,
0730-
0830 kun til å gå ute på arbeidsplassene
8895 til læreren. Dette for å kunne svare på små og store problem, gi tips
8896 og råd, eller bare for å plukke opp hva som er behovet ute i
8897 undervisningsarealene. Det er dessverre ikke slik at alle lærerne har
8898 nok digital kompetanse til å kunne formulere alle spørsmålene de har,
8899 men ved å kunne få vise eller lufte tanker med IKT-ansvarlig så er det
8900 utrolig hva som kommer fram.

8904 <li
>Jeg ser at mange bruker økonomi som argument i forhold til å bruke
8905 SkoleLinux, og jeg skal ikke legge skjul på at det var dette som i
8906 utgangspunktet var årsaken til vårt valg. Men diskusjonene og kampen
8907 med kommunens IT-avdeling har gjort at vi har fått et noe annet
8908 fokus. Fordelene med drift og stabilitet, gjør at vi ville ha valgt
8909 samme løsning selv om den var dyrere. At vi slipper langt billigere
8910 unna, som følge av
0,- lisenskostnader og lave maskinvarekostnader, er
8911 bare en bonus.

8914 andre skolene i kommunen bruker på IT, så har vi fått gehør for å få
8915 samme midler til innkjøp. Dette har gjort at vi nå kan kjøpe inn
8916 utstyr som de andre skolene bare kan se langt etter. Vi har nettopp
8917 kjøpt inn
3 videokamera i semiproff-klassen for å kunne lage film,
8918 samt sende live fra skoleteater/konserter. Vi har kjøpt inn digitale
8919 kompaktkamera til alle klassene. Vi har et team av lærere som skal i
8920 gang med å teste ut tablets på svake elever. Håpet et at teknologien
8921 kan være med på å gi noen av elevene litt mer motivasjon. Vi har kjøpt
8922 inn et halvt klassesett med pulsklokker, noe som har vist seg å være
8923 overraskende inspirerende for en del av elevene. Vi har også oss på
8924 fag på en høyskole litt lengre sør for oss, slik at
3 av oss nå skal
8925 ta faget
"Linux tjenestedrift
". Som inspektør og en del av skolens
8926 administrasjon er det veldig praktisk å kunne trå til hvis det
8927 kniper. Men IKT-ansvarlig har vært UTROLIG flink til å lage rene
8928 smørbrødlister for hvordan de mest vanlige driftsproblem løses, så det
8929 er lett for flere av oss å ta del i den daglige driften. Vi har svært
8930 stor nytte av lærling (som også hjelper to av naboskolene), men det er
8931 nesten blitt slik at det er om å gjøre å komme til først for å få løse
8932 problem. Det å få fingrene på problem og utfordringer er den aller
8933 beste læremester.

8946 håper at vi nå framover kan få tid til å bidra. Vi er i ferd med å
8947 bytte ut en av serverne våre, og da vil denne trolig bli satt opp som
8948 testserver for neste versjon av Skolelinux. På den måten vil vi i alle
8949 fall kunne gi tilbakemeldinger og rapportere feil. I tillegg så vil
8950 det kanskje gi oss noen nye utfordringer, for som lærlingen vår sier:

8970 years the university have organised shared bid of a few thousand
8971 computers, and this year HP won the bid. Two different desktops and
8972 five different laptops are on the list this year. We in the UNIX

8978 perhaps inspire others to test hardware as well. To test, I PXE
8979 install the OS version of choice, and log in as my normal user and run
8980 a few applications and plug in selected pieces of hardware. When
8981 something fail, I make a note about this in the test matrix and move
8982 on. If I have some spare time I try to report the bug to the OS
8983 vendor, but as I only have the machines for a short time, I rarely
8984 have the time to do this for all the problems I find.

9079 <title>Why isn

9083 <description><p
>In the latest issue of Linux Journal, the readers choices were
9084 presented, and the winner among the multimedia player were VLC.
9085 Personally, I like VLC, and it is my player of choice when I first try
9086 to play a video file or stream. Only if VLC fail will I drag out
9087 gmplayer to see if it can do better. The reason is mostly the failure
9088 model and trust. When VLC fail, it normally pop up a error message
9089 reporting the problem. When mplayer fail, it normally segfault or
9090 just hangs. The latter failure mode drain my trust in the program.
<p
>
9092 <p
>But even if VLC is my player of choice, we have choosen to use
9093 mplayer in
<a href=
"http://www.skolelinux.org/
">Debian
9094 Edu/Skolelinux
</a
>. The reason is simple. We need a good browser
9095 plugin to play web videos seamlessly, and the VLC browser plugin is
9096 not very good. For example, it lack in-line control buttons, so there
9097 is no way for the user to pause the video. Also, when I
9098 <a href=
"http://wiki.debian.org/DebianEdu/BrowserMultimedia
">last
9099 tested the browser plugins
</a
> available in Debian, the VLC plugin
9100 failed on several video pages where mplayer based plugins worked. If
9101 the browser plugin for VLC was as good as the gecko-mediaplayer
9102 package (which uses mplayer), we would switch.
</P
>
9104 <p
>While VLC is a good player, its user interface is slightly
9105 annoying. The most annoying feature is its inconsistent use of
9106 keyboard shortcuts. When the player is in full screen mode, its
9107 shortcuts are different from when it is playing the video in a window.
9108 For example, space only work as pause when in full screen mode. I
9109 wish it had consisten shortcuts and that space also would work when in
9110 window mode. Another nice shortcut in gmplayer is [enter] to restart
9111 the current video. It is very nice when playing short videos from the
9112 web and want to restart it when new people arrive to have a look at
9113 what is going on.

9881 architecture in Debian as a file server in NUUG to get access to the
5
9882 TB zfs volume we currently use to store DV video. Because of this, I
9883 finally got around to do a test installation of Debian/Squeeze with
9884 kfreebsd. Installation went fairly smooth, thought I noticed some
9885 visual glitches in the cdebconf dialogs (black cursor left on the
9886 screen at random locations). Have not gotten very far with the
9887 testing. Noticed cfdisk did not work, but fdisk did so it was not a
9888 fatal problem. Have to spend some more time on it to see if it is
9889 useful as a file server for NUUG. Will try to find time to set up a
9890 gnash buildbot slave on the Debian Edu/Skolelinux this weekend.

>Prioritising packages for the Debian Edu /
9900 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
> DVD, which is
9901 supposed provide a school with all the services and user applications
9902 needed on the pupils computer network has always been hard. Even
9903 schools without Internet connections should be able to get Debian Edu
9904 working using this DVD.
</p
>
9906 <p
>The job became a lot harder when apt and aptitude started
9907 installing recommended packages by default. We want the same set of
9908 packages to be installed when using the DVD and the netinst CD, and
9909 that means all recommended packages need to be on the DVD. I created
9910 a patch for debian-cd in
<a href=
"http://bugs.debian.org/
601203">BTS
9911 report #
601203</a
> to do this, and since this change was applied to
9912 the Debian Edu DVD build, we have been seriously short on space.
</p
>
9914 <p
>A few days ago we decided to drop blender, wxmaxima and kicad from
9915 the default installation to save space on the DVD, believing that
9916 those needing these applications are few and can get them from the
9917 Debian archive.
</p
>
9919 <p
>Yesterday, I had a look what source packages to see which packages
9920 were using most space. A few large packages are well know;
9921 openoffice.org, openclipart and fluid-soundfont. But I also
9922 discovered that lilypond used
106 MiB and fglrx-driver used
53 MiB.
9923 The lilypond package is pulled in as a dependency for rosegarden, and
9924 when looking a bit closer I discovered that
99 MiB of the
106 MiB were
9925 the documentation package, which is recommended by the binary package.
9926 I decided to drop this documentation package from our DVD, as most of
9927 our users will use the GUI front-ends and do not need the lilypond
9928 documentation. Similarly, I dropped the non-free fglrx-driver package
9929 which might be installed by d-i when its hardware is detected, as the
9930 free X driver should work.
</p
>
9932 <p
>With this change, we finally got space for the LXDE and Gnome
9933 desktop packages as well as the language specific packages making the
9934 DVD more useful again.

9945 <p
>My
<a href=
"http://pledgebank.com/gnash-avm2
">gnash pledge
</a
> to
9946 raise money for the project is going well. The lower limit of
10
9947 signers was reached in
24 hours, and so far
13 people have signed it.
9948 More signers and more funding is most welcome, and I am really curious
9949 how far we can get before the time limit of December
24 is reached.
9952 <p
>On the #gnash IRC channel on irc.freenode.net, I was just tipped
9953 about what appear to be a great code coverage tool capable of
9954 generating code coverage stats without any changes to the source code.
9956 <a href=
"http://simonkagstrom.github.com/kcov/index.html
">kcov
</a
>,
9957 and can be used using
<tt
>kcov
&lt;directory
&gt;
&lt;binary
&gt;
</tt
>.
9958 It is missing in Debian, but the git source built just fine in Squeeze
9959 after I installed libelf-dev, libdwarf-dev, pkg-config and
9960 libglib2.0-dev. Failed to build in Lenny, but suspect that is
9961 solvable. I hope kcov make it into Debian soon.
</p

9963 <p
>Finally found time to wrap up the release notes for

">a
9965 new alpha release of Debian Edu

9966 alpha test release of the Squeeze based Debian Edu /
9967 <a href=

">Skolelinux
</a
>
9968 release. Give it a try if you need a complete linux solution for your
9969 school, including central infrastructure server, workstations, thin
9970 client servers and diskless workstations. A nice touch added
9971 yesterday is RDP support on the thin client servers, for windows
9972 clients to get a Linux desktop on request.

10014 to include the latest version of Gnash that will make this happen, as
10015 the new release
0.8.8 was published a few weeks ago and is resting in
10016 unstable. The new version work with more sites that version
0.8.7.
10017 The Gnash maintainers have asked for a freeze exception, but the

10020 accept the new package into Squeeze.

10194 <description><p
>As reported earlier, the last few days I have looked at how Debian
10195 Edu clients are configured, and tried to get rid of all hardcoded
10196 configuration settings on the clients. I believe the work to be
10197 mostly done, and the clients seem to work just fine with dynamically
10198 generated configuration.
</p
>
10200 <p
>What is the point, you might ask? The point is to allow a Debian
10201 Edu desktop to integrate into an existing network infrastructure
10202 without any manual configuration.
</p
>
10204 <p
>This is what happens when installing a Debian Edu client here at
10205 the University of Oslo using PXE. With the PXE installation, I am
10206 asked for language (Norwegian Bokmål), locality (Norway) and keyboard
10207 layout (no-latin1), Debian Edu profile (Roaming Workstation), if I
10208 accept to reformat the hard drive (yes), if I want to submit info to
10209 popcon.debian.org (no) and root password (secret). After answering
10210 these questions, the installer goes ahead and does its thing, and
10211 after around
50 minutes it is done. I press enter to finish the
10212 installation, and the machine reboots into KDE. When the machine is
10213 ready and kdm asks for login information, I enter my university
10214 username and password, am told by kdm that a local home directory has
10215 been created and that I must log in again, and finally log in with the
10216 same username and password to the KDE
4.4 desktop. At no point during
10217 this process did it ask for university specific settings, and all the
10218 required configuration was dynamically detected using information
10219 fetched via DHCP and DNS. The roaming workstation is now ready for
10222 <p
>How was this done, you might wonder? First of all, here is the
10223 list of things that need to be configured on the client to get it
10224 working properly out of the box:
</p
>
10227 <li
>IP address/netmask and DNS server.
</li
>
10228 <li
>Web proxy URL.
</li
>
10229 <li
>LDAP server for NSS directory information (user, group, etc).
</li
>
10230 <li
>Kerberos server for PAM password checking.
</li
>
10231 <li
>SMB mount point to access the network home directory. (*)
</li
>
10232 <li
>Central syslog server to send syslog messages to. (*)
</li
>
10233 <li
>Sitesummary collector URL to submit info to central server. (*)
</li
>
10236 <p
>(Hm, did I forget anything? Let me knew if I did.)
</p
>
10238 <p
>The points marked (*) are not required to be able to use the
10239 machine, but needed to provide central storage and allowing system
10240 administrators to track their machines. Since yesterday, everything
10241 but the sitesummary collector URL is dynamically discovered at boot
10242 and installation time in the svn version of Debian Edu.
</p
>
10244 <p
>The IP and DNS setup is fetched during boot using DHCP as usual.
10245 When a DHCP update arrives, the proxy setup is updated by looking for
10246 http://wpat/wpad.dat and using the content of this WPAD file to
10247 configure the http and ftp proxy in /etc/environment and
10248 /etc/apt/apt.conf. I decided to update the proxy setup using a DHCP
10249 hook to ensure that the client stops using the Debian Edu proxy when
10250 it is moved outside the Debian Edu network, and instead uses any local
10251 proxy present on the new network when it moves around.
</p
>
10253 <p
>The DNS names of the LDAP, Kerberos and syslog server and related
10254 configuration are generated using DNS information at boot. First the
10255 installer looks for a host named ldap in the current DNS domain. If
10256 not found, it looks for _ldap._tcp SRV records in DNS instead. If an
10257 LDAP server is found, its root DSE entry is requested and the
10258 attributes namingContexts and defaultNamingContext are used to
10259 determine which LDAP base to use for NSS. If there are several
10260 namingContexts attibutes and the defaultNamingContext is present, that
10261 LDAP subtree is used as the base. If defaultNamingContext is missing,
10262 the subtrees listed as namingContexts are searched in sequence for any
10263 object with class posixAccount or posixGroup, and the first one with
10264 such an object is used as the LDAP base. For Kerberos, a similar
10265 search is done by first looking for a host named kerberos, and then
10266 for the _kerberos._tcp SRV record. I
've been unable to find a way to
10267 look up the Kerberos realm, so for this the upper case string of the
10268 current DNS domain is used.
</p
>
10270 <p
>For the syslog server, the hosts syslog and loghost are searched
10271 for, and the _syslog._udp SRV record is consulted if no such host is
10272 found. This algorithm works for both Debian Edu and the University of
10273 Oslo. A similar strategy would work for locating the sitesummary
10274 server, but have not been implemented yet. I decided to fetch and
10275 save these settings during installation, to make sure moving to a
10276 different network does not change the set of users being allowed to
10277 log in nor the passwords required to log in. Usernames and passwords
10278 will be cached by sssd when the user logs in on the Debian Edu
10279 network, and will not change as the laptop move around. For a
10280 non-roaming machine, there is no caching, but given that it is
10281 supposed to stay in place it should not matter much. Perhaps we
10282 should switch those to use sssd too?
</p
>
10284 <p
>The user
's SMB mount point for the network home directory is
10285 located when the user logs in for the first time. The LDAP server is
10286 consulted to look for the user
's LDAP object and the sambaHomePath
10287 attribute is used if found. If it isn
't found, the home directory
10288 path fetched from NSS is used instead. Assuming the path is of the
10289 form /site/server/directory/username, the second part is looked up in
10290 DNS and used to generate a SMB URL of the form
10291 smb://server.domain/username. This algorithm works for both Debian
10292 edu and the University of Oslo. Perhaps there are better attributes
10293 to use or a better algorithm that works for more sites, but this will
10294 do for now. :)
</p
>
10296 <p
>This work should make it easier to integrate the Debian Edu clients
10297 into any LDAP/Kerberos infrastructure, and make the current setup even
10298 more flexible than before. I suspect it will also work for thin
10299 client servers, allowing one to easily set up LTSP and hook it into a
10300 existing network infrastructure, but I have not had time to test this
10303 <p
>If you want to help out with implementing these things for Debian
10304 Edu, please contact us on debian-edu@lists.debian.org.
</p
>
10306 <p
>Update
2010-
08-
09: Simon Farnsworth gave me a heads-up on how to
10307 detect Kerberos realm from DNS, by looking for _kerberos TXT entries
10308 before falling back to the upper case DNS domain name. Will have to
10309 implement it for Debian Edu. :)

10318 <description><p
>A few years ago, I was involved in a project planning to use
10319 Windows file servers as home directory servers for Debian
10320 Edu/Skolelinux machines. This was thought to be no problem, as the
10321 access would be through the SMB network file system protocol, and we
10322 knew other sites used SMB with unix and samba as the file server to
10323 mount home directories without any problems. But, after months of
10324 struggling, we had to conclude that our goal was impossible.
</p
>
10326 <p
>The reason is simply that while SMB can be used for home
10327 directories when the file server is Samba running on Unix, this only
10328 work because of Samba have some extensions and the fact that the
10329 underlying file system is a unix file system. When using a Windows
10330 file server, the underlying file system do not have POSIX semantics,
10331 and several programs will fail if the users home directory where they
10332 want to store their configuration lack POSIX semantics.
</p
>
10334 <p
>As part of this work, I wrote a small C program I want to share
10335 with you all, to replicate a few of the problematic applications (like
10336 OpenOffice.org and GCompris) and see if the file system was working as
10337 it should. If you find yourself in spooky file system land, it might

>A few days ago, I
10550 <a href=
"http://people.skolelinux.org/pere/blog/Debian_Edu_roaming_workstation___at_the_university_of_Oslo.html
">tried
10551 to install
</a
> a Roaming workation profile from Debian Edu/Squeeze
10552 while on the university network here at the University of Oslo, and
10553 noticed how much had to change to get it operational using the
10554 university infrastructure. It was fairly easy, but it occured to me
10555 that Debian Edu would improve a lot if I could get the client to
10556 connect without any changes at all, and thus let the client configure
10557 itself during installation and first boot to use the infrastructure
10558 around it. Now I am a huge step further along that road.
</p
>
10560 <p
>With our current squeeze-test packages, I can select the roaming
10561 workstation profile and get a working laptop connecting to the
10562 university LDAP server for user and group and our active directory
10563 servers for Kerberos authentication. All this without any
10564 configuration at all during installation. My users home directory got
10565 a bookmark in the KDE menu to mount it via SMB, with the correct URL.
10566 In short, openldap and sssd is correctly configured. In addition to
10567 this, the client look for http://wpad/wpad.dat to configure a web
10568 proxy, and when it fail to find it no proxy settings are stored in
10569 /etc/environment and /etc/apt/apt.conf. Iceweasel and KDE is
10570 configured to look for the same wpad configuration and also do not use
10571 a proxy when at the university network. If the machine is moved to a
10572 network with such wpad setup, it would automatically use it when DHCP
10573 gave it a IP address.
</p
>
10575 <p
>The LDAP server is located using DNS, by first looking for the DNS
10576 entry ldap.$domain. If this do not exist, it look for the
10577 _ldap._tcp.$domain SRV records and use the first one as the LDAP
10578 server. Next, it connects to the LDAP server and search all
10579 namingContexts entries for posixAccount or posixGroup objects, and
10580 pick the first one as the LDAP base. For Kerberos, a similar
10581 algorithm is used to locate the LDAP server, and the realm is the
10582 uppercase version of $domain.
</p
>
10584 <p
>So, what is not working, you might ask. SMB mounting my home
10585 directory do not work. No idea why, but suspected the incorrect
10586 Kerberos settings in /etc/krb5.conf and /etc/samba/smb.conf might be
10587 the cause. These are not properly configured during installation, and
10588 had to be hand-edited to get the correct Kerberos realm and server,
10589 but SMB mounting still do not work. :(
</p
>
10591 <p
>With this automatic configuration in place, I expect a Debian Edu
10592 roaming profile installation would be able to automatically detect and
10593 connect to any site using LDAP and Kerberos for NSS directory and PAM
10594 authentication. It should also work out of the box in a Active
10595 Directory environment providing posixAccount and posixGroup objects
10596 with UID and GID values.

>The new roaming workstation profile in Debian Edu/Squeeze is fairly
10609 similar to the laptop setup am I working on using Ubuntu for the
10610 University of Oslo, and just for the heck of it, I tested today how
10611 hard it would be to integrate that profile into the university
10612 infrastructure. In this case, it is the university LDAP server,
10613 Active Directory Kerberos server and SMB mounting from the Netapp file
10616 <p
>I was pleasantly surprised that the only three files needed to be
10617 changed (/etc/sssd/sssd.conf, /etc/ldap.conf and
10618 /etc/mklocaluser.d/
20-debian-edu-config) and one file had to be added
10619 (/usr/share/perl5/Debian/Edu_Local.pm), to get the client working.
10620 Most of the changes were to get the client to use the university LDAP
10621 for NSS and Kerberos server for PAM, but one was to change a hard
10622 coded DNS domain name in the mklocaluser hook from .intern to
10625 <p
>This testing was so encouraging, that I went ahead and adjusted the
10626 Debian Edu scripts and setup in subversion to centralise the roaming
10627 workstation setup a bit more and avoid the hardcoded DNS domain name,
10628 so that when I test this tomorrow, I expect to get away with modifying
10629 only /etc/sssd/sssd.conf and /etc/ldap.conf to get it to use the
10630 university servers.
</p
>
10632 <p
>My goal is to get the clients to have no hardcoded settings and
10633 fetch all their initial setup during installation and first boot, to
10634 allow them to be inserted also into environments where the default
10635 setup in Debian Edu has been changed or as with the university, where
10636 the environment is different but provides the protocols Debian Edu

>The last few months me and the other Debian Edu developers have
10766 been working hard to get the Debian/Squeeze based version of Debian
10767 Edu/Skolelinux into shape. This future version will use Kerberos for
10768 authentication, and services are slowly migrated to single signon,
10769 getting rid of password questions one at the time.
</p
>
10771 <p
>It will also feature a roaming workstation profile with local home
10772 directory, for laptops that are only some times on the Skolelinux
10773 network, and for this profile a shortcut is created in Gnome and KDE
10774 to gain access to the users home directory on the file server. This
10775 shortcut uses SMB at the moment, and yesterday I had time to test if
10776 SMB mounting had started working in KDE after we added the cifs-utils
10777 package. I was pleasantly surprised how well it worked.
</p
>
10779 <p
>Thanks to the recent changes to our samba configuration to get it
10780 to use Kerberos for authentication, there were no question about user
10781 password when mounting the SMB volume. A simple click on the shortcut
10782 in the KDE menu, and a window with the home directory popped
10785 <p

10786 Debian Edu. We already had PAM, LDAP, IMAP and SMTP in place, and now
10787 also Samba. Next step is Cups and hopefully also NFS.

10789 <p

10790 to the autobuilder administrators for some architectures being slow to
10791 sign packages, we are still missing the fixed LTSP package we need for
10792 the release. It was uploaded three days ago with urgency=high, and if
10793 it had entered testing yesterday we would have been able to test it in
10794 time for a alpha0 release today. As the binaries for ia64 and powerpc
10795 still not uploaded to the Debian archive, we need to delay the alpha
10796 release another day.

10831 <p
>PowerDNS have two modes of operation using LDAP as its backend.
10832 One
"strict
" mode where the forward and reverse DNS lookups are done
10833 using the same LDAP objects, and a
"tree
" mode where the forward and
10834 reverse entries are in two different subtrees in LDAP with a structure
10835 based on the DNS names, as in tjener.intern and
10836 2.2.0.10.in-addr.arpa.
</p
>
10838 <p
>In tree mode, the server is set up to use a LDAP subtree as its
10839 base, and uses a
"base
" scoped search for the DNS name by adding
10840 "dc=tjener,dc=intern,
" to the base with a filter for
10841 "(associateddomain=tjener.intern)
" for the forward entry and
10842 "dc=
2,dc=
2,dc=
0,dc=
10,dc=in-addr,dc=arpa,
" with a filter for
10843 "(associateddomain=
2.2.0.10.in-addr.arpa)
" for the reverse entry. For
10844 forward entries, it is looking for attributes named dnsttl, arecord,
10845 nsrecord, cnamerecord, soarecord, ptrrecord, hinforecord, mxrecord,
10846 txtrecord, rprecord, afsdbrecord, keyrecord, aaaarecord, locrecord,

10848 ipseckeyrecord, rrsigrecord, nsecrecord, dnskeyrecord, dhcidrecord,

10850 the attributes dnsttl, arecord, nsrecord, cnamerecord, soarecord,
10851 ptrrecord, hinforecord, mxrecord, txtrecord, rprecord, aaaarecord,

11128 DHCP services in Debian Edu to use the same LDAP objects for a given
11129 computer, to avoid the possibility of having a inconsistent state for
11130 a computer in LDAP (as in DHCP but no DNS entry or the other way
11131 around) and make it easier to add computers to LDAP.

11137 One forward DNS entry, one reverse DNS entry and one DHCP entry. If
11138 we switch powerdns to use its strict LDAP method (ldap-method=strict

11140 merged into one while making it impossible to transfer the reverse map
11141 to a slave DNS server.

11143 <p
>If we also replace the object class used to get the DNS related
11144 attributes to one allowing these attributes to be combined with the

11146 I
've written such object class in the dnsdomainaux.schema file (need
11147 proper OIDs, but that is a minor issue), and tested the setup. It
11148 seem to work.

11150 <p

11396 <description><p
>For a laptop, centralized user directories and password checking is
11397 a bit troubling. Laptops are typically used also when not connected
11398 to the network, and it is vital for a user to be able to log in or
11399 unlock the screen saver also when a central server is unavailable.
11400 This is possible by caching passwords and directory information (user
11401 and group attributes) locally, and the packages to do so are available
11402 in Debian. Here follow two recipes to set this up in Debian/Squeeze.
11403 It is also possible to set up in Debian/Lenny, but require more manual
11404 setup there because pam-auth-update is missing in Lenny.
</p
>
11406 <h2
>LDAP/Kerberos + nscd + libpam-ccreds + libpam-mklocaluser/pam_mkhomedir
</h2
>
11408 This is the traditional method with a twist. The password caching is
11409 provided by libpam-ccreds (version
10-
4 or later is needed on
11410 Squeeze), and the directory caching is done by nscd. The directory
11411 lookup and password checking is done using LDAP. If one want to use
11412 Kerberos for password checking the libpam-ldapd package can be
11413 replaced with libpam-krb5 or libpam-heimdal. If one is happy having a
11414 local home directory with the path listed in LDAP, one can use the
11415 pam_mkhomedir module from pam-modules to make this happen instead of
11416 using libpam-mklocaluser. A setup for pam-auth-update to enable
11417 pam_mkhomedir will have to be written until a fix for
11418 <a href=
"http://bugs.debian.org/
568577">bug #
568577</a
> is in the
11419 archive. Because I believe it is a bad idea to have local home
11420 directories using misleading paths like /site/server/partition/, I
11421 prefer to create a local user with the home directory in /home/. This
11422 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
11603 directory in Debian Edu, and in the process I started to miss a GUI
11604 tool to browse the LDAP tree. The only one I was able to find in
11605 Debian/Squeeze and Lenny is
11606 <a href=
"http://luma.sourceforge.net/
">LUMA
</a
>, which has proved to
11607 be a great tool to get a overview of the current LDAP directory
11608 populated by default in Skolelinux. Thanks to it, I have been able to
11609 find empty and obsolete subtrees, misplaced objects and duplicate
11610 objects. It will be installed by default in Debian/Squeeze. If you
11611 are working with LDAP, give it a go. :)
</p
>
11613 <p
>I did notice one problem with it I have not had time to report to
11614 the BTS yet. There is no .desktop file in the package, so the tool do
11615 not show up in the Gnome and KDE menus, but only deep down in in the
11616 Debian submenu in KDE. I hope that can be fixed before Squeeze is
11617 released.
</p

11619 <p
>I have not yet been able to get it to modify the tree yet. I would
11620 like to move objects and remove subtrees directly in the GUI, but have
11621 not found a way to do that with LUMA yet. So in the mean time, I use
11622 <a href=

11629 useful GUI alternative. It seem like a good tool, but is unmaintained
11630 in Debian and got a RC bug keeping it out of Squeeze. Unless that
11631 changes, it will not be an option for Debian Edu based on Squeeze.

>A while back, I
11641 <a href=
"http://people.skolelinux.org/pere/blog/Time_for_new__LDAP_schemas_replacing_RFC_2307_.html
">complained
11642 about the fact
</a
> that it is not possible with the provided schemas
11643 for storing DNS and DHCP information in LDAP to combine the two sets
11644 of information into one LDAP object representing a computer.
</p
>
11646 <p
>In the mean time, I discovered that a simple fix would be to make
11647 the dhcpHost object class auxiliary, to allow it to be combined with
11648 the dNSDomain object class, and thus forming one object for one
11649 computer when storing both DHCP and DNS information in LDAP.
</p
>
11651 <p
>If I understand this correctly, it is not safe to do this change
11652 without also changing the assigned number for the object class, and I
11653 do not know enough about LDAP schema design to do that properly for
11654 Debian Edu.
</p

11656 <p

11658 <a href=
"http://tools.ietf.org/html/draft-ietf-dhc-ldap-schema-

</a

">testing
11692 of Debian upgrades
</a

've
11693 finally made the upgrade logs available from
11694 <a href=
"http://people.skolelinux.org/pere/debian-upgrade-testing/
">http://people.skolelinux.org/pere/debian-upgrade-testing/
</a
>.
11695 I am now testing dist-upgrade of Gnome and KDE in a chroot using both
11696 apt and aptitude, and found their differences interesting. This time
11697 I will only focus on their removal plans.
</p
>
11699 <p
>After installing a Gnome desktop and the laptop task, apt-get wants
11700 to remove
72 packages when dist-upgrading from Lenny to Squeeze. The
11701 surprising part is that it want to remove xorg and all
11702 xserver-xorg-video* drivers. Clearly not a good choice, but I am not
11703 sure why. When asking aptitude to do the same, it want to remove
129
11704 packages, but most of them are library packages I suspect are no
11705 longer needed. Both of them want to remove bluetooth packages, which
11706 I do not know. Perhaps these bluetooth packages are obsolete?
</p
>
11708 <p
>For KDE, apt-get want to remove
82 packages, among them kdebase
11709 which seem like a bad idea and xorg the same way as with Gnome. Asking
11710 aptitude for the same, it wants to remove
192 packages, none which are
11711 too surprising.
</p
>
11713 <p
>I guess the removal of xorg during upgrades should be investigated
11714 and avoided, and perhaps others as well. Here are the complete list
11715 of planned removals. The complete logs is available from the URL
11716 above. Note if you want to repeat these tests, that the upgrade test
11717 for kde+apt-get hung in the tasksel setup because of dpkg asking
11718 conffile questions. No idea why. I worked around it by using
11719 '<tt
>echo
>> /proc/
<em
>pidofdpkg
</em
>/fd/
0</tt
>' to tell dpkg to
11720 continue.

11866 <description><p
>The last few days I have done some upgrade testing in Debian, to
11867 see if the upgrade from Lenny to Squeeze will go smoothly. A few bugs
11868 have been discovered and reported in the process
11869 (
<a href=
"http://bugs.debian.org/
585410">#
585410</a
> in nagios3-cgi,
11870 <a href=
"http://bugs.debian.org/
584879">#
584879</a
> already fixed in
11871 enscript and
<a href=
"http://bugs.debian.org/
584861">#
584861</a
> in
11872 kdebase-workspace-data), and to get a more regular testing going on, I
11873 am working on a script to automate the test.
</p
>
11875 <p
>The idea is to create a Lenny chroot and use tasksel to install a
11876 Gnome or KDE desktop installation inside the chroot before upgrading
11877 it. To ensure no services are started in the chroot, a policy-rc.d
11878 script is inserted. To make sure tasksel believe it is to install a
11879 desktop on a laptop, the tasksel tests are replaced in the chroot
11880 (only acceptable because this is a throw-away chroot).
</p
>
11882 <p
>A naive upgrade from Lenny to Squeeze using aptitude dist-upgrade
11883 currently always fail because udev refuses to upgrade with the kernel
11884 in Lenny, so to avoid that problem the file /etc/udev/kernel-upgrade
11885 is created. The bug report
11886 <a href=
"http://bugs.debian.org/
566000">#
566000</a
> make me suspect
11887 this problem do not trigger in a chroot, but I touch the file anyway
11888 to make sure the upgrade go well. Testing on virtual and real
11889 hardware have failed me because of udev so far, and creating this file
11890 do the trick in such settings anyway. This is a
11891 <a href=
"http://www.linuxquestions.org/questions/debian-
26/failed-dist-upgrade-due-to-udev-config_sysfs_deprecated-nonsense-
804130/
">known
11892 issue
</a
> and the current udev behaviour is intended by the udev
11893 maintainer because he lack the resources to rewrite udev to keep
11894 working with old kernels or something like that. I really wish the
11895 udev upstream would keep udev backwards compatible, to avoid such
11896 upgrade problem, but given that they fail to do so, I guess
11897 documenting the way out of this mess is the best option we got for
11898 Debian Squeeze.

>Som systemarkitekten bak Skolelinux, kan jeg bare riste på hodet
12024 over påstanden om at Skolelinux krever desentraliserte tjenere.
12025 Skolelinux-arkitekturen er laget for sentralisert drift og plassering
12026 av tjenerne lokalt eller sentralt alt etter behov og nettkapasitet.
12027 Den er modellert på nettverks- og tjenerløsningen som brukes på
12028 Universitetet i Tromsø og Oslo, der jeg jobber med utvikling av
12029 driftstjenester. Dette er det heldigvis noen som har fått med seg, og
12030 jeg er glad for å kunne sitere fra en kommentar på den overnevnte
12031 artikkelen. Min venn og gamle kollega Sturle Sunde forteller der:
12034 <p
>I Flora kommune køyrer vi Skulelinux på skular med alt frå
15 til
12035 meir enn
500 elevar. Dei store skulane har eigen tenar, for det er
12036 mest praktisk. Eg, som er driftsansvarleg for heile nettet, ser
12037 sjeldan dei tenarane fysisk, men at dei står der gjer skulane mindre
12038 avhengige av eksterne linjer som er trege eller dyre. Dei minste
12039 skulane har ikkje eigen tenar. Å bruke sentral tenar er heller ikkje
12040 noko problem. Småskulane klarar seg fint med
1 mbit-linje til ein
12041 sentral tenar eller tenaren på ein større skule.
</p
>
12043 <p
>Det beste med Skulelinux er halvtjukke klientar. Dei treng ikkje
12044 harddisk og brukar minimalt med ressursar på tenaren fordi dei køyrer
12045 programma lokalt. Eit klasserom med
30 sju-åtte år gamle maskiner har
12046 mykje meir CPU og RAM totalt enn nokon moderne tenar til under
12047 millionen. Det trengst to kommandoar på den sentrale tenaren for å
12048 oppdatere alle klientane, både tynne og halvtjukke. Vi har ingen
12049 problem med diskar som ryk heller, som var eit problem før fordi
12050 elevane sat og sparka i maskinene. Og dei krev lite bandbreidde i
12051 nettet, so det er fullt mogleg å køyre slike på småskular med trege
12052 linjer mot tenaren på ein større skule.
</p

12054 <p
>Flora kommune har nesten
800 Linux-maskiner i sitt skulenett, og
12055 ein person som tek seg av drift av heile nettet, inkludert tenarar,
12056 klientar, operativsystem, programvare, heimekontorløysing og
12057 administrasjon av brukarar.

>After a long break from debian-installer development, I finally
12211 found time today to return to the project. Having to spend less time
12212 working dependency based boot in debian, as it is almost complete now,
12213 definitely helped freeing some time.
</p
>
12215 <p
>A while back, I ran into a problem while working on Debian Edu. We
12216 include some firmware packages on the Debian Edu CDs, those needed to
12217 get disk and network controllers working. Without having these
12218 firmware packages available during installation, it is impossible to
12219 install Debian Edu on the given machine, and because our target group
12220 are non-technical people, asking them to provide firmware packages on
12221 an external medium is a support pain. Initially, I expected it to be
12222 enough to include the firmware packages on the CD to get
12223 debian-installer to find and use them. This proved to be wrong.
12224 Next, I hoped it was enough to symlink the relevant firmware packages
12225 to some useful location on the CD (tried /cdrom/ and
12226 /cdrom/firmware/). This also proved to not work, and at this point I
12227 found time to look at the debian-installer code to figure out what was
12228 going to work.
</p
>
12230 <p
>The firmware loading code is in the hw-detect package, and a closer
12231 look revealed that it would only look for firmware packages outside
12232 the installation media, so the CD was never checked for firmware
12233 packages. It would only check USB sticks, floppies and other
12234 "external
" media devices. Today I changed it to also look in the
12235 /cdrom/firmware/ directory on the mounted CD or DVD, which should
12236 solve the problem I ran into with Debian edu. I also changed it to
12237 look in /firmware/, to make sure the installer also find firmware
12238 provided in the initrd when booting the installer via PXE, to allow us
12239 to provide the same feature in the PXE setup included in Debian
12242 <p
>To make sure firmware deb packages with a license questions are not
12243 activated without asking if the license is accepted, I extended
12244 hw-detect to look for preinst scripts in the firmware packages, and
12245 run these before activating the firmware during installation. The
12246 license question is asked using debconf in the preinst, so this should
12247 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
12260 Edu finally entered the Debian archive. Today, the new
12261 <a href=
"http://packages.qa.debian.org/libp/libpam-mklocaluser.html
">libpam-mklocaluser
</a

12262 package was accepted. Two days ago, two other pieces was accepted

12265 package needed by libpam-mklocaluser, and the

12267 passed NEW on Monday. In addition, the
12268 <a href=

">libpam-ccreds
</a
>
12269 package we need is in experimental (version
10-
4) since Saturday, and
12270 hopefully will be moved to unstable soon.
</p
>
12272 <p
>This collection of packages allow for two different setups for
12273 roaming laptops. The traditional setup would be using libpam-ccreds,
12274 nscd and libpam-mklocaluser with LDAP or Kerberos authentication,
12275 which should work out of the box if the configuration changes proposed
12276 for nscd in
<a href=
"http://bugs.debian.org/
485282">BTS report
12277 #
485282</a
> is implemented. The alternative setup is to use sssd with
12278 libpam-mklocaluser to connect to LDAP or Kerberos and let sssd take
12279 care of the caching of passwords and group information.
</p
>
12281 <p
>I have so far been unable to get sssd to work with the LDAP server
12282 at the University, but suspect the issue is some SSL/GnuTLS related
12283 problem with the server certificate. I plan to update the Debian
12284 package to version
1.2, which is scheduled for next week, and hope to
12285 find time to make sure the next release will include both the
12286 Debian/Ubuntu specific patches. Upstream is friendly and responsive,
12287 and I am sure we will find a good solution.
</p
>
12289 <p
>The idea is to set up the roaming laptops to authenticate using
12290 LDAP or Kerberos and create a local user with home directory in /home/
12291 when a usre in LDAP logs in via KDM or GDM for the first time, and
12292 cache the password for offline checking, as well as caching group
12293 memberhips and other relevant LDAP information. The
12294 libpam-mklocaluser package was created to make sure the local home
12295 directory is in /home/, instead of /site/server/directory/ which would
12296 be the home directory if pam_mkhomedir was used. To avoid confusion
12297 with support requests and configuration, we do not want local laptops
12298 to have users in a path that is used for the same users home directory
12299 on the home directory servers.
</p
>
12301 <p
>One annoying problem with gdm is that it do not show the PAM
12302 message passed to the user from libpam-mklocaluser when the local user
12303 is created. Instead gdm simply reject the login with some generic
12304 message. The message is shown in kdm, ssh and login, so I guess it is
12305 a bug in gdm. Have not investigated if there is some other message
12306 type that can be used instead to get gdm to also show the message.

>In the recent Debian Edu versions, the
12353 <a href=
"http://wiki.debian.org/DebianEdu/HowTo/SiteSummary
">sitesummary
12354 system
</a
> is used to keep track of the machines in the school
12355 network. Each machine will automatically report its status to the
12356 central server after boot and once per night. The network setup is
12357 also reported, and using this information it is possible to get the
12358 MAC address of all network interfaces in the machines. This is useful
12359 to update the DHCP configuration.
</p

12361 <p
>To give some idea how to use sitesummary, here is a one-liner to
12362 ist all MAC addresses of all machines reporting to sitesummary. Run
12363 this on the collector host:

12365 <blockquote

12366 perl -MSiteSummary -e
'for_all_hosts(sub { print join(
" ", get_macaddresses(shift)),
"\n
"; });
'
12367 </pre
></blockquote
>
12369 <p
>This will list all MAC addresses assosiated with all machine, one
12370 line per machine and with space between the MAC addresses.
</p
>
12372 <p
>To allow system administrators easier job at adding static DHCP
12373 addresses for hosts, it would be possible to extend this to fetch
12374 machine information from sitesummary and update the DHCP and DNS
12375 tables in LDAP using this information. Such tool is unfortunately not
12376 written yet.

12463 <description><p
>For some years now, I have wondered how we should handle laptops in
12464 Debian Edu. The Debian Edu infrastructure is mostly designed to
12465 handle stationary computers, and less suited for computers that come
12468 <p
>Now I finally believe I have an sensible idea on how to adjust
12469 Debian Edu for laptops, by introducing a new profile for them, for
12470 example called Roaming Workstations. Here are my thought on this.
12471 The setup would consist of the following:
</p
>
12475 <li
>During installation, the user name of the owner / primary user of
12476 the laptop is requested and a local home directory is set up for
12477 the user, with uid and gid information fetched from the LDAP
12478 server. This allow the user to work also when offline. The
12479 central home directory can be available in a subdirectory on
12480 request, for example mounted via CIFS. It could be mounted
12481 automatically when a user log in while on the Debian Edu network,
12482 and unmounted when the machine is taken away (network down,
12483 hibernate, etc), it can be set up to do automatic mounting on
12484 request (using autofs), or perhaps some GUI button on the desktop
12485 can be used to access it when needed. Perhaps it is enough to use
12486 the fish protocol in KDE?
</li
>
12488 <li
>Password checking is set up to use LDAP or Kerberos
12489 authentication when the machine is on the Debian Edu network, and
12490 to cache the password for offline checking when the machine unable
12491 to reach the LDAP or Kerberos server. This can be done using
12492 <a href=
"http://www.padl.com/OSS/pam_ccreds.html
">libpam-ccreds
</a
>
12493 or the Fedora developed
12494 <a href=
"https://fedoraproject.org/wiki/Features/SSSD
">System
12495 Security Services Daemon
</a
> packages.
</li
>
12497 <li
>File synchronisation with the central home directory is set up
12498 using a shared directory in both the local and the central home
12499 directory, using unison.
</li
>
12501 <li
>Printing should be set up to print to all printers broadcasting
12502 their existence on the local network, and should then work out of
12503 the box with CUPS. For sites needing accurate printer quotas, some
12504 system with Kerberos authentication or printing via ssh could be
12505 implemented.
</li
>
12507 <li
>For users that should have local root access to their laptop,
12508 sudo should be used to allow this to the local user.
</li
>
12510 <li
>It would be nice if user and group information from LDAP is
12511 cached on the client, but given that there are entries for the
12512 local user and primary group in /etc/, it should not be needed.
</li
>
12516 <p
>I believe all the pieces to implement this are in Debian/testing at
12517 the moment. If we work quickly, we should be able to get this ready
12518 in time for the Squeeze release to freeze. Some of the pieces need
12519 tweaking, like libpam-ccreds should get support for pam-auth-update
12520 (
<a href=
"http://bugs.debian.org/
566718">#
566718</a
>) and nslcd (or
12521 perhaps debian-edu-config) should get some integration code to stop
12522 its daemon when the LDAP server is unavailable to avoid long timeouts
12523 when disconnected from the net. If we get Kerberos enabled, we need
12524 to make sure we avoid long timeouts there too.

"http://www.nuug.no/aktiviteter/

">Yesterdays
12537 NUUG presentation
</a
> about Kerberos was inspiring, and reminded me
12538 about the need to start using Kerberos in Skolelinux. Setting up a
12539 Kerberos server seem to be straight forward, and if we get this in
12540 place a long time before the Squeeze version of Debian freezes, we
12541 have a chance to migrate Skolelinux away from NFSv3 for the home
12542 directories, and over to an architecture where the infrastructure do
12543 not have to trust IP addresses and machines, and instead can trust
12544 users and cryptographic keys instead.
</p
>
12546 <p
>A challenge will be integration and administration. Is there a
12547 Kerberos implementation for Debian where one can control the
12548 administration access in Kerberos using LDAP groups? With it, the
12549 school administration will have to maintain access control using flat
12550 files on the main server, which give a huge potential for errors.
</p
>
12552 <p
>A related question I would like to know is how well Kerberos and
12553 pam-ccreds (offline password check) work together. Anyone know?
</p
>
12555 <p
>Next step will be to use Kerberos for access control in Lwat and
12556 Nagios. I have no idea how much work that will be to implement. We
12557 would also need to document how to integrate with Windows AD, as such
12558 shared network will require two Kerberos realms that need to cooperate
12559 to work properly.
</p
>
12561 <p
>I believe a good start would be to start using Kerberos on the
12562 skolelinux.no machines, and this way get ourselves experience with
12563 configuration and integration. A natural starting point would be
12564 setting up ldap.skolelinux.no as the Kerberos server, and migrate the
12565 rest of the machines from PAM via LDAP to PAM via Kerberos one at the
12568 <p
>If you would like to contribute to get this working in Skolelinux,
12569 I recommend you to see the video recording from yesterdays NUUG
12570 presentation, and start using Kerberos at home. The video show show
12571 up in a few days.

>6 years ago, as part of the Debian Edu development I am involved
12581 in, I asked for a hook in the kdm and gdm setup to run scripts as root
12582 when the user log out. A bug was submitted against the xfree86-common
12583 package in
2004 (
<a href=
"http://bugs.debian.org/
230422">#
230422</a

12584 and revisited every time Debian Edu was working on a new release.
12585 Today, this finally paid off.
</p
>
12587 <p
>The framework for this feature was today commited to the git
12588 repositry for the xorg package, and the git repository for xdm has
12589 been updated to use this framework. Next on my agenda is to make sure
12590 kdm and gdm also add code to use this framework.
</p
>
12592 <p
>In Debian Edu, we want to ability to run commands as root when the
12593 user log out, to get rid of runaway processes and do general cleanup
12594 after a user. With this framework in place, we finally can do that in
12595 a generic way that work with all display managers using this
12596 framework. My goal is to get all display managers in Debian use it,
12597 similar to how they use the Xsession.d framework today.

>One of the new features in the next Debian/Lenny based release of
12629 Debian Edu/Skolelinux, which is scheduled for release in the next few
12630 days, is automatic configuration of the service monitoring system
12631 Nagios. The previous release had automatic configuration of trend
12632 analysis using Munin, and this Lenny based release take that a step
12635 <p
>When installing a Debian Edu Main-server, it is automatically
12636 configured as a Munin and Nagios server. In addition, it is
12637 configured to be a server for the
12638 <a href=
"http://wiki.debian.org/DebianEdu/HowTo/SiteSummary
">SiteSummary
12639 system
</a
> I have written for use in Debian Edu. The SiteSummary
12640 system is inspired by a system used by the University of Oslo where I
12641 work. In short, the system provide a centralised collector of
12642 information about the computers on the network, and a client on each
12643 computer submitting information to this collector. This allow for
12644 automatic information on which packages are installed on each machine,
12645 which kernel the machines are using, what kind of configuration the
12646 packages got etc. This also allow us to automatically generate Munin
12647 and Nagios configuration.
</p
>
12649 <p
>All computers reporting to the sitesummary collector with the
12650 munin-node package installed is automatically enabled as a Munin
12651 client and graphs from the statistics collected from that machine show
12652 up automatically on http://www/munin/ on the Main-server.
</p
>
12654 <p
>All non-laptop computers reporting to the sitesummary collector are
12655 automatically monitored for network presence (ping and any network
12656 services detected). In addition, all computers (also laptops) with
12657 the nagios-nrpe-server package installed and configured the way
12658 sitesummary would configure it, are monitored for full disks, software
12659 raid status, swap free and other checks that need to run locally on
12660 the machine.
</p
>
12662 <p
>The result is that the administrator on a school using Debian Edu
12663 based on Lenny will be able to check the health of his installation
12664 with one look at the Nagios settings, without having to spend any time
12665 keeping the Nagios configuration up-to-date.
</p
>
12667 <p
>The only configuration one need to do to get Nagios up and running
12668 is to set the password used to get access via HTTP. The system
12669 administrator need to run
"<tt
>htpasswd /etc/nagios3/htpasswd.users
12670 nagiosadmin
</tt
>" to create a nagiosadmin user and set a password for
12671 it to be able to log into the Nagios web pages. After that,
12672 everything is taken care of.

12686 å få fri programvare og unix-lignende operativsystemer inn i Skolen.

12689 møtet, og hadde sans for ideen, men intet skjedde. På vårparten
12690 2001 ble det arrangert en demonstrasjon i anledning at First Tuesday
12691 hadde invitert Microsoft til et møte for å fortelle om fremtidens

12701 besteme jeg meg for å benytte anledningen hos Håkon til å snakke om
12702 behovet for å hjelpe skolene i gang med bedre datasystemer bestående
12703 av fri programvare og unix-lignende operativsystemer. Flere var

>I
'm sitting on the train going home from this weekends Debian
12742 Edu/Skolelinux development gathering. I got a bit done tuning the
12743 desktop, and looked into the dynamic service location protocol
12744 implementation avahi. It look like it could be useful for us. Almost
12745 30 people participated, and I believe it was a great environment to
12746 get to know the Skolelinux system. Walter Bender, involved in the
12747 development of the Sugar educational platform, presented his stuff and
12748 also helped me improve my OLPC installation. He also showed me that
12749 his Turtle Art application can be used in standalone mode, and we
12750 agreed that I would help getting it packaged for Debian. As a
12751 standalone application it would be great for Debian Edu. We also
12752 tried to get the video conferencing working with two OLPCs, but that
12753 proved to be too hard for us. The application seem to need more work
12754 before it is ready for me. I look forward to getting home and relax

>The state of standardized LDAP schemas on Linux is far from
12765 optimal. There is RFC
2307 documenting one way to store NIS maps in
12766 LDAP, and a modified version of this normally called RFC
2307bis, with
12767 some modifications to be compatible with Active Directory. The RFC
12768 specification handle the content of a lot of system databases, but do
12769 not handle DNS zones and DHCP configuration.

12772 we would like to store information about users, SMB clients/hosts,
12773 filegroups, netgroups (users and hosts), DHCP and DNS configuration,
12774 and LTSP configuration in LDAP. These objects have a lot in common,
12775 but with the current LDAP schemas it is not possible to have one
12776 object per entity. For example, one need to have at least three LDAP
12777 objects for a given computer, one with the SMB related stuff, one with
12778 DNS information and another with DHCP information. The schemas
12779 provided for DNS and DHCP are impossible to combine into one LDAP
12780 object. In addition, it is impossible to implement quick queries for
12781 netgroup membership, because of the way NIS triples are implemented.
12782 It just do not scale. I believe it is time for a few RFC
12783 specifications to cleam up this mess.

12788 It need to be efficently stored to make sure it scale well.

12825 <a href=
"http://no.speling.org/
">den norske stavekontrollen for bokmål
12826 og nynorsk
</a
> til å ikke bruke bindestrek som ordskillemarkør, lyktes jeg
12827 endelig første juledag. Bruken av bindestrek som ordskillemarkør har
12828 gjort det umulig å få med ord med bindestrek i
12829 stavekontrolldatagrunnlaget, slik at ord som e-post og CD-spiller ikke
12830 kunne godtas av stavekontrollen. Hadde litt tid til overs å bruke på
12831 stavekontrollen, og satte meg ned med to kopier av byggsystemet og en
12832 liten testdatafil, og byttet ut - med = på utvalgte steder i
12833 byggsystemet og datafilen helt til jeg fikk samme resultat med det
12834 gamle og det nye byggsystemet. Dette tror jeg var forsøk
4, der de
12835 foregående har feilet uten at jeg klarte å forstå hvorfor. Det sier
12836 kanskje litt om kompleksiteten i det originale byggsystemet som Rune
12837 Kleveland laget i sin tid.
</p

12839 <p
>Etter å ha endret byggsystemet, var neste steg å importere ordene
12840 med bindestrek. Vi har en rekke slike i databasene for

12844 for korrektur av datagrunnlaget for stavekontrollen, og etter importen
12845 skulle nå
10350 nye ord bli godkjent som korrekt stavede ord av

>This weekend we had a small developer gathering for Debian Edu in
12856 Oslo. Most of Saturday was used for the general assemly for the
12857 member organization, but the rest of the weekend I used to tune the
12858 LTSP installation. LTSP now work out of the box on the
10-network.
12859 Acer Aspire One proved to be a very nice thin client, with both
12860 screen, mouse and keybard in a small box. Was working on getting the
12861 diskless workstation setup configured out of the box, but did not
12862 finish it before the weekend was up.

12864 <p
>Did not find time to look at the
4 VGA cards in one box we got from
12865 the Brazilian group, so that will have to wait for the next
12866 development gathering. Would love to have the Debian Edu installer
12867 automatically detect and configure a multiseat setup when it find one
12868 of these cards.

>Recently I have spent some time evaluating the multimedia browser
12878 plugins available in Debian Lenny, to see which one we should use by
12879 default in Debian Edu. We need an embedded video playing plugin with
12880 control buttons to pause or stop the video, and capable of streaming
12881 all the multimedia content available on the web. The test results and
12882 notes are available on
12883 <a href=
"http://wiki.debian.org/DebianEdu/BrowserMultimedia
">the
12884 Debian wiki
</a
>. I was surprised how few of the plugins are able to
12885 fill this need. My personal video player favorite, VLC, has a really
12886 bad plugin which fail on a lot of the test pages. A lot of the MIME
12887 types I would expect to work with any free software player (like
12888 video/ogg), just do not work. And simple formats like the
12889 audio/x-mplegurl format (m3u playlists), just isn
't supported by the
12890 totem and vlc plugins. I hope the situation will improve soon. No
12891 wonder sites use the proprietary Adobe flash to play video.
