165 Debian Edu, also known as Skolelinux, is a Linux distribution based on
166 Debian providing an out-of-the box environment of a completely
167 configured school network. Directly after installation a school server
168 running all services needed for a school network is set up just
169 waiting for users and machines being added via GOsa², a comfortable
170 Web-UI. A netbooting environment is prepared using PXE, so after
171 initial installation of the main server from CD or USB stick all other
172 machines can be installed via the network. The provided school server
173 provides LDAP database and Kerberos authentication service,
174 centralized home directories, DHCP server, web proxy and many other
175 services. The desktop contains more than
60 educational software
176 packages and more are available from the Debian archive, and schools
177 can choose between KDE, GNOME, LXDE, Xfce and MATE desktop
182 The Debian Project was founded in
1993 by Ian Murdock to be a truly
183 free community project. Since then the project has grown to be one of
184 the largest and most influential open source projects. Thousands of
185 volunteers from all over the world work together to create and
186 maintain Debian software. Available in
70 languages, and supporting a
187 huge range of computer types, Debian calls itself the universal
192 Thanks to everyone making Debian and Debian Edu / Skolelinux happen!

>It was a surprise to me to learn that project to create a complete
204 computer system for schools I
've involved in,
205 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>, was
206 being used in India. But apparently it is, and I managed to get an
207 interview with one of the friends of the project there, Shirish
210 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
212 <p
>My name is Shirish Agarwal. Based out of the educational and
213 historical city of Pune, from the western state of Maharashtra, India.
214 My bread comes from giving training, giving policy tips,
215 installations on free software to mom and pop shops in different
216 fields from Desktop publishing to retail shops as well as work with
217 few software start-ups as well.
</p
>
219 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
220 project?
</strong
></p
>
222 <p
>It started innocently enough. I have been using Debian for a few
223 years and in one local minidebconf / debutsav I was asked if there was
224 anything for schools or education. I had worked / played with free
225 educational softwares such as Gcompris and Stellarium for my many
226 nieces and nephews so researched and found Debian Edu or Skolelinux as
227 it was known then. Since then I have started using the various
228 education meta-packages provided by the project.
</p
>
230 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
231 Edu?
</strong
></p
>
233 <p
>It
's closest I have seen where a package full of educational
234 software are packed, which are free and open (both literally and
235 figuratively). Even if I take the simplest software which is
236 gcompris, the number of activities therein are amazing. Another one of
237 the softwares that I have liked for a long time is stellarium. Even
238 pysycache is cool except for couple of issues I encountered
239 <a href=
"https://bugs.debian.org/
781841">#
781841</a
> and
240 <a href=
"https://bugs.debian.org/
781842">#
781842</a
>.
</p
>
242 <p
>I prefer software installed on the system over web based solutions,
243 as a web site can disappear any time but the software on disk has the
244 possibility of a larger life span. Of course with both it
's more a
245 question if it has enough users who make it fun or sustainable or both
246 for the developer per-se.
</p
>
248 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
249 Edu?
</strong
></p
>
251 <p
>I do see that the Debian Edu team seems to be short-handed and I
252 think more efforts should be made to make it popular and ask and take
253 help from people and the larger community wherever possible.
</p
>
255 <p
>I don
't see any disadvantage to use Skolelinux apart from the fact
256 that most apps. are generic which is good or bad how you see it.
257 However, saying that I do acknowledge the fact that the canvas is
258 pretty big and there are lot of interesting ideas that could be done
259 but for reasons not known not done or if done I don
't know about them.
260 Let me share some of the ideas (these are more upstream based but
261 still) I have had for a long time :
</p
>
263 <p
>1. Classical maths question of two trains in opposing directions
264 each running @x kmph/mph at y distance, when they will meet and how
265 far would each travel and similar questions like these.
267 <p
>The computer is a fantastic system where questions like these can
268 be drawn, animated and the methodology and answers teased out in
269 interactive manner. While sites such as the
270 <a href=
"http://mathforum.org/dr.math/faq/faq.two.trains.html
">Ask
271 Dr. Math FAQ on The Two Trains problem
</a
> (as an example or point of
272 inspiration) can be used there is lot more that can be done. I dunno
273 if there is a free software which does something like this. The idea
274 being a blend of objects + animation + interaction which does
275 this. The whole interaction could be gamified with points or sounds or
276 colourful celebration whenever the user gets even part of the question
277 or/and methodology right. That would help reinforce good behaviour.
278 This understanding could be used to share/showcase everything from how
279 the first wheel came to be, to evolution to how astronomy started,
280 psychics and everything in-between.
</p
>
282 <p
>One specific idea in the train part was having the Linux mascot on
283 one train and the BSD or GNU mascot on the other train and they
284 meeting somewhere in-between. Characters from blender movies could
285 also be used.
</p
>
287 <p
>2. Loads of crossword-puzzles with reference to subjects: We have
288 enormous data sets in Wikipedia and Wikitionary. I don
't think it
289 should be a big job to design crossword puzzles. Using categories and
290 sub-categories it should be doable to have Q
&A single word answers
291 from the existing data-sets. What would make it easy or hard could be
292 the length of the word + existence of many or few vowels depending on
293 the user
's input.
</p
>
295 <p
>3. Jigsaw puzzles - We already have a great software called
296 palapeli with number of slicers making it pretty interesting. What
297 needs to be done is to download large number of public domain and
298 copyleft images, tease and use IPTC tags to categorise them into
299 nature, history etc. and let it loose. This could turn to be really
300 huge collection of images. One source could be taken from
301 commons.wikimedia.org, others could be huge collection of royalty-free
302 stock photos. Potential is immense.
</p
>
304 <p
>Apart from this, free software suffers in two directions, we lag
305 both in development (of using new features per-se) and maintenance a
306 lot. This is more so in educational software as these applications
307 need to be timely and the opportunity cost of missing deadlines is
308 immense. If we are able to solve issues of funding for development and
309 maintenance of such software I don
't see any big difficulties. I know
310 of few start-ups in and around India who would love to develop and
311 maintain such software if funding issues could be solved.
</p
>
313 <p
><strong
>Which free software do you use daily?
</strong
></p
>
315 <p
>That would be huge list. Some of the softwares are obviously apt,
316 aptitude, debdelta, leafpad, the shell of course (zsh nowadays),
317 quassel for IRC. In games I use shisen-sho while card-games are evenly
318 between kpat and Aiselriot. In desktops it
's a tie between
319 gnome-flashback and mate.
</p
>
321 <p
><strong
>Which strategy do you believe is the right one to use to
322 get schools to use free software?
</strong
></p
>
324 <p
>I think it should first start with using specific FOSS apps. in
325 whatever environment they are. If it
's MS-Windows or Mac so be it.
326 Once they are habitual with the apps. and there is buy-in from the
327 school management then it could be installed anywhere. Most of the
328 people now understand the concept of a repository because of the
329 various online stores so it isn
't hard to convince on that front.
</p
>
331 <p
>What is harder is having enough people with technical skills and
332 passion to service them. If you get buy-in from one or two teachers
333 then ideas like above could also be asked to be done as a project as
336 <p
>I think where we fall short more than anything is in marketing. For
337 instance, Debian has this whole range of fonts in its archive but
338 there isn
't even a page where all those different fonts in the La
339 Ipsum format could be tried out for newcomers.
</p
>
341 <p
>One of the issues faced constantly in installations is with updates
342 and upgrades. People have this myth that each update and upgrade
343 means the user interface will / has to change. I have seen this
344 innumerable times. That perhaps is one of the reasons which browsers
345 like Iceweasel / Firefox change user interfaces so much, not because
346 it might be needed or be functional but because people believe that
347 changed user interfaces are better. This, can easily be pointed with
348 the user interfaces changed with almost every MS-Windows and Mac OS
351 <p
>The problems with Debian Edu for deployment are many. The biggest
352 is the huge gap between what is taught in schools and what Debian Edu
355 <p
>Me and my friends did teach on week-ends in a government school for
357 <a href=
"https://flossexperiences.wordpress.com/
2012/
10/
08/sharings/
">gathered
358 some experience
</a
> there. Some of the things we learnt/discovered
359 there was :
</p
>
363 <li
>Most of the teachers are very territorial about their subjects
364 and they do not want you to teach anything out of the
365 portion/syllabus given.
</li
>
367 <li
>They want any activity on the system in accordance to whatever
368 is in the syllabus.
</li
>
370 <li
>There are huge barriers both with the English language and at
371 times with objects or whatever. An example, let
's say in gcompris
372 you have objects falling down and you have to name them and let
's
373 say the falling object is a hat or a fedora hat, this would not be
374 as recognizable as say a
375 <a href=
"https://en.wikipedia.org/wiki/Puneri_Pagadi
">Puneri
376 Pagdi
</a
> so there is need to inject local objects, words wherever
377 possible. Especially for word-games there are so many hindi words
378 which have become part of english vocabulary (for instance in
379 parley), those could be made into a hinglish collection or
380 something but that is something for upstream to do.

580 powerful desktop with education software, a central server providing
581 web pages, user database, user home directories, central login and PXE
582 boot of both clients without disk and the installation to install Debian
583 Edu on machines with disk (and a few other services perhaps to small
584 to mention here). We in the Debian Edu team are currently working on
585 the Jessie based version, trying to get everything in shape before the
586 freeze, to avoid having to maintain our own package repository in the
588 <a href=
"https://wiki.debian.org/DebianEdu/Status/Jessie
">current
589 status
</a
> can be seen on the Debian wiki, and there is still heaps of
590 work left. Some fatal problems block testing, breaking the installer,
591 but it is possible to work around these to get anyway. Here is a
592 recipe on how to get the installation limping along.
</p
>
594 <p
>First, download the test ISO via
595 <a href=
"ftp://ftp.skolelinux.no/cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-
1.iso
">ftp
</a
>,
596 <a href=

1.iso
">http
</a
>
598 ftp.skolelinux.org::cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-
1.iso).
599 The ISO build was broken on Tuesday, so we do not get a new ISO every
600 12 hours or so, but thankfully the ISO we already got we are able to
601 install with some tweaking.
</p
>
603 <p
>When you get to the Debian Edu profile question, go to tty2
604 (use Alt-Ctrl-F2), run
</p
>
606 <p
><blockquote
><pre
>
607 nano /usr/bin/edu-eatmydata-install
608 </pre
></blockquote
></p
>
610 <p
>and add
'exit
0' as the second line, disabling the eatmydata
611 optimization. Return to the installation, select the profile you want
612 and continue. Without this change, exim4-config will fail to install
613 due to a known bug in eatmydata.
</p
>
615 <p
>When you get the grub question at the end, answer /dev/sda (or if
616 this do not work, figure out what your correct value would be. All my
617 test machines need /dev/sda, so I have no advice if it do not fit
620 <p
>If you installed a profile including a graphical desktop, log in as
621 root after the initial boot from hard drive, and install the
622 education-desktop-XXX metapackage. XXX can be kde, gnome, lxde, xfce
623 or mate. If you want several desktop options, install more than one
624 metapackage. Once this is done, reboot and you should have a working
625 graphical login screen. This workaround should no longer be needed
626 once the education-tasks package version
1.801 enter testing in two
629 <p
>I believe the ISO build will start working on two days when the new
630 tasksel package enter testing and Steve McIntyre get a chance to
631 update the debian-cd git repository. The eatmydata, grub and desktop
632 issues are already fixed in unstable and testing, and should show up
633 on the ISO as soon as the ISO build start working again. Well the
634 eatmydata optimization is really just disabled. The proper fix
635 require an upload by the eatmydata maintainer applying the patch
636 provided in bug
<a href=
"https://bugs.debian.org/
702711">#
702711</a
>.
637 The rest have proper fixes in unstable.
</p
>
639 <p
>I hope this get you going with the installation testing, as we are
640 quickly running out of time trying to get our Jessie based
641 installation ready before the distribution freeze in a month.

<a href=

651 a lot quicker. When we install more than
2000 packages in
652 <a href=
"http://www.skolelinux.org/
">Skolelinux / Debian Edu
</a
> using
653 tasksel in the installer, unpacking the binary packages take forever.
654 A part of the slow I/O issue was discussed in
655 <a href=
"https://bugs.debian.org/
613428">bug #
613428</a
> about too
656 much file system sync-ing done by dpkg, which is the package
657 responsible for unpacking the binary packages. Other parts (like code
658 executed by postinst scripts) might also sync to disk during
659 installation. All this sync-ing to disk do not really make sense to
660 me. If the machine crash half-way through, I start over, I do not try
661 to salvage the half installed system. So the failure sync-ing is
662 supposed to protect against, hardware or system crash, is not really
663 relevant while the installer is running.
</p
>
665 <p
>A few days ago, I thought of a way to get rid of all the file
666 system sync()-ing in a fairly non-intrusive way, without the need to
667 change the code in several packages. The idea is not new, but I have
668 not heard anyone propose the approach using dpkg-divert before. It
669 depend on the small and clever package
670 <a href=
"https://packages.qa.debian.org/eatmydata
">eatmydata
</a
>, which
671 uses LD_PRELOAD to replace the system functions for syncing data to
672 disk with functions doing nothing, thus allowing programs to live
673 dangerous while speeding up disk I/O significantly. Instead of
674 modifying the implementation of dpkg, apt and tasksel (which are the
675 packages responsible for selecting, fetching and installing packages),
676 it occurred to me that we could just divert the programs away, replace
677 them with a simple shell wrapper calling
678 "eatmydata
&nbsp;$program
&nbsp;$@
", to get the same effect.
679 Two days ago I decided to test the idea, and wrapped up a simple
680 implementation for the Debian Edu udeb.
</p
>
682 <p
>The effect was stunning. In my first test it reduced the running
683 time of the pkgsel step (installing tasks) from
64 to less than
44
684 minutes (
20 minutes shaved off the installation) on an old Dell
685 Latitude D505 machine. I am not quite sure what the optimised time
686 would have been, as I messed up the testing a bit, causing the debconf
687 priority to get low enough for two questions to pop up during
688 installation. As soon as I saw the questions I moved the installation
689 along, but do not know how long the question were holding up the
690 installation. I did some more measurements using Debian Edu Jessie,
691 and got these results. The time measured is the time stamp in
692 /var/log/syslog between the
"pkgsel: starting tasksel
" and the
693 "pkgsel: finishing up
" lines, if you want to do the same measurement
694 yourself. In Debian Edu, the tasksel dialog do not show up, and the
695 timing thus do not depend on how quickly the user handle the tasksel

744 <p
>The test is done using a netinst ISO on a USB stick, so some of the
745 time is spent downloading packages. The connection to the Internet
746 was
100Mbit/s during testing, so downloading should not be a
747 significant factor in the measurement. Download typically took a few
748 seconds to a few minutes, depending on the amount of packages being
751 <p
>The speedup is implemented by using two hooks in
752 <a href=
"https://www.debian.org/devel/debian-installer/
">Debian
753 Installer
</a
>, the pre-pkgsel.d hook to set up the diverts, and the
754 finish-install.d hook to remove the divert at the end of the
755 installation. I picked the pre-pkgsel.d hook instead of the
756 post-base-installer.d hook because I test using an ISO without the
757 eatmydata package included, and the post-base-installer.d hook in
758 Debian Edu can only operate on packages included in the ISO. The
759 negative effect of this is that I am unable to activate this
760 optimization for the kernel installation step in d-i. If the code is
761 moved to the post-base-installer.d hook, the speedup would be larger
762 for the entire installation.

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

838 <p

839 Debian installer too? I suspect it should, but am not sure the
840 current debian-installer coordinators find it useful enough. It also
841 depend on the side effects of the change. I
'm not aware of any, but I
842 guess we will see if the change is safe after some more testing.
843 Perhaps there is some package in Debian depending on sync() and
844 fsync() having effect? Perhaps it should go into its own udeb, to
845 allow those of us wanting to enable it to do so without affecting
848 <p
>Update
2014-
09-
24: Since a few days ago, enabling this optimization
849 will break installation of all programs using gnutls because of
850 <a href=
"https://bugs.debian.org/
702711">bug #

>. An updated
851 eatmydata package in Debian will solve it.

853 <p
>Update
2014-
10-
17: The bug mentioned above is fixed in testing and
854 the optimization work again. And I have discovered that the
855 dpkg-divert trick is not really needed and implemented a slightly
856 simpler approach as part of the debian-edu-install package. See
857 tools/edu-eatmydata-install in the source package.

860 <a href=
"http://bugs.debian.org/

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

30 laptops as mobile
926 workstations. Then the pupils have the possibility to work with these

>The
<a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
962 project
</a
> provide an instruction manual for teachers, system
963 administrators and other users that contain useful tips for setting up
964 and maintaining a Debian Edu installation. This text is about how the
965 text processing of this manual is handled in the project.
</p
>
967 <p
>One goal of the project is to provide information in the native
968 language of its users, and for this we need to handle translations.
969 But we also want to make sure each language contain the same
970 information, so for this we need a good way to keep the translations
971 in sync. And we want it to be easy for our users to improve the
972 documentation, avoiding the need to learn special formats or tools to
973 contribute, and the obvious way to do this is to make it possible to
974 edit the documentation using a web browser. We also want it to be
975 easy for translators to keep the translation up to date, and give them
976 help in figuring out what need to be translated. Here is the list of
977 tools and the process we have found trying to reach all these
980 <p
>We maintain the authoritative source of our manual in the
981 <a href=
"https://wiki.debian.org/DebianEdu/Documentation/Wheezy/
">Debian
982 wiki
</a
>, as several wiki pages written in English. It consist of one
983 front page with references to the different chapters, several pages
984 for each chapter, and finally one
"collection page
" gluing all the
985 chapters together into one large web page (aka
986 <a href=
"https://wiki.debian.org/DebianEdu/Documentation/Wheezy/AllInOne
">the
987 AllInOne page
</a
>). The AllInOne page is the one used for further
988 processing and translations. Thanks to the fact that the
989 <a href=
"http://moinmo.in/
">MoinMoin
</a
> installation on
990 wiki.debian.org support exporting pages in
991 <a href=
"http://www.docbook.org/
">the Docbook format
</a
>, we can fetch
992 the list of pages to export using the raw version of the AllInOne
993 page, loop over each of them to generate a Docbook XML version of the
994 manual. This process also download images and transform image
995 references to use the locally downloaded images. The generated
996 Docbook XML files are slightly broken, so some post-processing is done
997 using the
<tt
>documentation/scripts/get_manual
</tt
> program, and the
998 result is a nice Docbook XML file (debian-edu-wheezy-manual.xml) and
999 a handfull of images. The XML file can now be used to generate PDF, HTML
1000 and epub versions of the English manual. This is the basic step of
1001 our process, making PDF (using dblatex), HTML (using xsltproc) and
1002 epub (using dbtoepub) version from Docbook XML, and the resulting files
1003 are placed in the debian-edu-doc-en binary package.
</p
>
1005 <p
>But English documentation is not enough for us. We want translated
1006 documentation too, and we want to make it easy for translators to
1007 track the English original. For this we use the
1008 <a href=
"http://packages.qa.debian.org/p/poxml.html
">poxml
</a
> package,
1009 which allow us to transform the English Docbook XML file into a
1010 translation file (a .pot file), usable with the normal gettext based
1011 translation tools used by those translating free software. The pot
1012 file is used to create and maintain translation files (several .po
1013 files), which the translations update with the native language
1014 translations of all titles, paragraphs and blocks of text in the
1015 original. The next step is combining the original English Docbook XML
1016 and the translation file (say debian-edu-wheezy-manual.nb.po), to
1017 create a translated Docbook XML file (in this case
1018 debian-edu-wheezy-manual.nb.xml). This translated (or partly
1019 translated, if the translation is not complete) Docbook XML file can
1020 then be used like the original to create a PDF, HTML and epub version
1021 of the documentation.
</p
>
1023 <p
>The translators use different tools to edit the .po files. We
1025 <a href=
"http://www.kde.org/applications/development/lokalize/
">lokalize
</a
>,
1026 while some use emacs and vi, others can use web based editors like
1027 <a href=
"http://pootle.translatehouse.org/
">Poodle
</a
> or
1028 <a href=
"https://www.transifex.com/
">Transifex
</a
>. All we care about
1029 is where the .po file end up, in our git repository. Updated
1030 translations can either be committed directly to git, or submitted as
1031 <a href=
"https://bugs.debian.org/src:debian-edu-doc
">bug reports
1032 against the debian-edu-doc package
</a
>.
</p
>
1034 <p
>One challenge is images, which both might need to be translated (if
1035 they show translated user applications), and are needed in different
1036 formats when creating PDF and HTML versions (epub is a HTML version in
1037 this regard). For this we transform the original PNG images to the
1038 needed density and format during build, and have a way to provide
1039 translated images by storing translated versions in
1040 images/$LANGUAGECODE/. I am a bit unsure about the details here. The
1041 package maintainers know more.
</p
>
1043 <p
>If you wonder what the result look like, we provide
1044 <a href=
"http://maintainer.skolelinux.org/debian-edu-doc/
">the content
1045 of the documentation packages on the web
</a

1068 keep gaining new users. Some weeks ago, a person showed up on IRC,
1069 <a href=
"irc://irc.debian.org/#debian-edu
">#debian-edu
</a
>, with a
1070 wish to contribute, and I managed to get a interview with this great
1071 contributor Roger Marsal to learn more about his background.
</p
>
1073 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
1075 <p
>My name is Roger Marsal, I
'm
27 years old (
1986 generation) and I
1076 live in Barcelona, Spain. I
've got a strong business background and I
1077 work as a patrimony manager and as a real estate agent. Additionally,
1078 I
've co-founded a British based tech company that is nowadays on the
1079 last development phase of a new social networking concept.
</p
>
1081 <p
>I
'm a Linux enthusiast that started its journey with Ubuntu four years
1082 ago and have recently switched to Debian seeking rock solid stability
1083 and as a necessary step to gain expertise.
</p
>
1085 <p
>In a nutshell, I spend my days working and learning as much as I
1086 can to face both my job, entrepreneur project and feed my Linux
1089 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
1090 project?
</strong
></p
>
1092 <p
>I discovered the
<a href=
"http://www.ltsp.org/
">LTSP
</a
> advantages
1093 with
"Ubuntu
12.04 alternate install
" and after a year of use I
1094 started looking for an alternative. Even though I highly value and
1095 respect the Ubuntu project, I thought it was necessary for me to
1096 change to a more robust and stable alternative. As far as I was using
1097 Debian on my personal laptop I thought it would be fine to install
1098 Debian and configure an LTSP server myself. Surprised, I discovered
1099 that the Debian project also supported a kind of Edubuntu equivalent,
1100 and after having some pain I obtained a Debian Edu network up and
1101 running. I just loved it.
</p
>
1103 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
1104 Edu?
</strong
></p
>
1106 <p
>I found a main advantage in that, once you know
"the tips and
1107 tricks
", a new installation just works out of the box. It
's the most
1108 complete alternative I
've found to create an LTSP network. All the
1109 other distributions seems to be made of plastic, Debian Edu seems to
1110 be made of steel.
</p
>
1112 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
1113 Edu?
</strong
></p
>
1115 <p
>I found two main disadvantages.
</p
>
1117 <p
>I
'm not an expert but I
've got notions and I had to spent a considerable
1118 amount of time trying to bring up a standard network topology. I
'm quite
1119 stubborn and I just worked until I did but I
'm sure many people with few
1120 resources (not big schools, but academies for example) would have switched
1121 or dropped.
</p
>
1123 <p
>It
's amazing how such a complex system like Debian Edu has achieved
1124 this out-of-the-box state. Even though tweaking without breaking gets
1125 more difficult, as more factors have to be considered. This can
1126 discourage many people too.
</p
>
1128 <p
><strong
>Which free software do you use daily?
</strong
></p
>
1130 <p
>I use Debian, Firefox, Okular, Inkscape, LibreOffice and
1131 Virtualbox.
</p
>
1134 <p
><strong
>Which strategy do you believe is the right one to use to
1135 get schools to use free software?
</strong
></p
>
1137 <p
>I don
't think there is a need for a particular strategy. The free
1138 attribute in both
"freedom
" and
"no price
" meanings is what will
1139 really bring free software to schools. In my experience I can think of
1140 the
<a href=
"http://www.r-project.org/
">"R
" statistical language
</a
>; a
1141 few years a ago was an extremely nerd tool for university people.
1142 Today it
's being increasingly used to teach statistics at many
1143 different level of studies. I believe free and open software will
1144 increasingly gain popularity, but I
'm sure schools will be one of the
1145 first scenarios where this will happen.

>On larger sites, it is useful to use a dedicated storage server for
1155 storing user home directories and data. The design for handling this
1156 in
<a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>, is
1157 to update the automount rules in LDAP and let the automount daemon on
1158 the clients take care of the rest. I was reminded about the need to
1159 document this better when one of the customers of
1160 <a href=
"http://www.slxdrift.no/
">Skolelinux Drift AS
</a
>, where I am
1161 on the board of directors, asked about how to do this. The steps to
1162 get this working are the following:
</p
>
1166 <li
>Add new storage server in DNS. I use nas-server.intern as the
1167 example host here.
</li
>
1169 <li
>Add automoun LDAP information about this server in LDAP, to allow
1170 all clients to automatically mount it on reqeust.
</li
>
1172 <li
>Add the relevant entries in tjener.intern:/etc/fstab, because
1173 tjener.intern do not use automount to avoid mounting loops.
</li
>
1175 </ol
></p
>
1177 <p
>DNS entries are added in GOsa², and not described here. Follow the
1178 <a href=
"https://wiki.debian.org/DebianEdu/Documentation/Wheezy/GettingStarted
">instructions
1179 in the manual
</a
> (Machine Management with GOsa² in section Getting
1182 <p
>Ensure that the NFS export points on the server are exported to the
1183 relevant subnets or machines:

1192 <p
>Here everything on the backbone network is granted access to the
1193 /storage export. With NFSv3 it is slightly better to limit it to
1194 netgroup membership or single IP addresses to have some limits on the
1195 NFS access.
</p
>
1197 <p
>The next step is to update LDAP. This can not be done using GOsa²,
1198 because it lack a module for automount. Instead, use ldapvi and add
1199 the required LDAP objects using an editor.

1205 <p
>When the editor show up, add the following LDAP objects at the
1206 bottom of the document. The
"/
&" part in the last LDAP object is a
1207 wild card matching everything the nas-server exports, removing the
1208 need to list individual mount points in LDAP.

1227 <p

1228 tjener.intern by adding them to /etc/fstab, creating the mount
1229 directories using mkdir and running
"mount -a

1231 <p

1255 <p
>I am a
23 year-old student from Germany who has spent half of his
1256 life with open source. In
"real life
", I am, as already mentioned, a
1257 student in the fields of Computer Science, Electrical Engineering,
1258 Information Technologies and Anglistics. Due to my (only partially
1259 voluntary) huge engagement in the open source world, these things are
1260 a bit vacant right now however.
</p
>
1262 <p
>I also have been working as a project teacher at a Gymasnium
1263 (public school) for various years now. I took up that work some time
1264 around
2005 when still attending that school myself and have continued
1265 it until today. I also had been running the (kind of very advanced)
1266 network of that school together with a team of very interested and
1267 talented students in the age of
11 to
15 years, who took the chance to
1268 learn a lot about open source and networking before I left the school
1269 to help building another school

1272 <p
>That said, one might see me as a kind of
"glue
" between school kids
1273 and the elderly of teachers as well as between the open source
1274 ecosystem and the (even more complex) educational ecosystem.
</p
>
1276 <p
>When I am not busy with open source or education, I like Geocaching
1277 and cycling.

1279 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
1280 project?
</strong

1282 <p
>I think that happened some time around
2009 when I first attended
1283 <a href=
"http://www.froscon.org
">FrOSCon
</a
> and visited the project
1284 booth. I think I wasn
't too interested back then because I used to
1285 have an attitude of disliking software that does too much stuff on its
1286 own. Maybe I was too inexperienced to realise the upsides of an
1287 "out-of-the-box
" solution ;).
</p
>
1289 <p
>The first time I actively talked to Skolelinux people was at
1290 <a href=
"http://www.openrheinruhr.de
">OpenRheinRuhr
</a
> 2011 when the
1291 BiscuIT project, a home-grewn software used by my school for various
1292 really cool things from timetables and class contact lists to lunch
1293 ordering, student ID card printing and project elections first got to
1294 a stage where it could have been published. I asked the Skolelinux
1295 guys running the booth if the project were interested in it and gave a
1296 small demonstration, but there wasn
't any real feedback and the guys
1297 seemed rather uninterested.
</p
>
1299 <p
>After I left the school where I developed the software, it got
1300 mostly lost, but I am now reimplementing it for my new school. I have
1301 reusability and compatibility in mind, and I hop there will be a new
1302 basis for contributing it to the Skolelinux project ;)!
</p
>
1304 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
1305 Edu?
</strong
></p
>
1307 <p
>The most important advantage seems to be that it
"just
1308 works
". After overcoming some minor (but still very annoying) glitches
1309 in the installer, I got a fully functional, working school network,
1310 without the month-long hassle I experienced when setting all that up
1311 from scratch in earlier years. And above that, it rocked - I didn
't
1312 have any real hardware at hand, because the school was just founded
1313 and has no money whatsoever, so I installed a combined server (main
1314 server, terminal services and workstation) in a VM on my personal
1315 notebook, bridging the LTSP network interface to the ethernet port,
1316 and then PXE-booted the Windows notebooks that were lying around from
1317 it. I could use
8 clients without any performance issues, by using a
1318 tiny little VM on a tiny little notebook. I think that
's enough to say
1319 that it rocks!
</p
>
1321 <p
>Secondly, there are marketing reasons. Life
's bad, and so no
1322 politician will ever permit a setup described as
"Debian, an universal
1323 operating system, with some really cool educational tools
" while they
1324 will be jsut fine with
"Skolelinux, a single-purpose solution for your
1325 school network
", even if both turn out to be the very same thing (yes,
1326 this is unfair towards the Skolelinux project, and must not be taken
1327 too seriously - you get the idea, anyway).

1332 <p

1333 answer this question in a fair way. Thus, please allow me to put it in
1334 other words:
"What do you expect from Skolelinux to keep liking it?

1335 can list a few points about that:

1367 are more efficient and powerful than anything else, I also use (or at

1369 kids. One of these things is

1374 <p

>Which strategy do you believe is the right one to use to
1375 get schools to use free software?
</strong
></p
>
1377 <p
>Well, that
's a two-sided thing. One side is what I believe, and one
1378 side is what I have experienced.
</p
>
1380 <p
>I believe that the right strategy is showing them the benefits. But
1381 that won
't work out as long as the acceptance of free alternatives
1382 grows globally. What I mean is that if all the kids are almost forced
1383 to use Windows, Facebook, Skype, you name it at home, they will not
1384 see why they would want to use alternatives at school. I have seen
1385 students take seat in front of a fully-functional, modern Debian
1386 desktop that could do anything their Windows at home could do, and
1387 they jsut refused to use it because
"Linux sucks
". It is something
1388 that makes the council of our city spend around
600000 € to buy
1389 software - not including hardware, mind you - for operating school
1390 networks, and for installing a system that, as has been proved, does
1391 not work. For those of you readers who are good at maths, have you
1392 already found out how many lives could have been saved with that money
1393 if we had instead used it to bring education to parts of the world
1394 that need it? I have, and found it to be nothing less dramatic than
1395 plain criminal.
</p
>
1397 <p
>That said, the only feasible way appears to be the bottom up
1398 method. We have to bring free software to kids and parents. I have
1399 founded an association named
1400 <a href=
"https://www.teckids.org
">Teckids
</a
> here in Germany that does
1401 just that. We organise several events for kids and adolescents in the
1402 area of free and open source software, for example the
1403 <a href=
"http://kids.froscon.org
">FrogLabs
</a
>, which share staff with
1404 Teckids and are the youth programme of
1405 <a href=
"http://www.froscon.org
">the Free and Open Source Software
1406 Conference (FrOSCon)
</a
>. We do a lot more than most other conferences
1407 - this year, we first offered the FrogLabs as a holiday camp for kids
1408 aged
10 to
16. It was a huge success, with approx.
30 kids taking part
1409 and learning with and about free software through a whole weekend. All
1410 of us had a lot of fun, and the results were really exciting.
</p
>
1412 <p
>Apart from that, we are preparing a campaign that is supposed to bring
1413 the message of free alternatives to stuff kids use every day to them and
1414 their parents, e.g. the use of Jabber / Jappix instead of Facebook and
1415 Skype. To make that possible, we are planning to get together a team of
1416 clever kids who understand very well what their peers need and can bring
1417 it across to them. So we will have a peer-driven network of adolescents
1418 who teach each other and collect feedback from the community of minors.
1419 We then take that feedback and our own experience to work closely with
1420 open source projects, such as Skolelinux or Jappix, at improving their
1421 software in a way that makes it more and more attractive for the target
1422 group. At least I hope that we will have good cooperation with
1423 Skolelinux in the future ;)!
</p
>
1425 <p
>So in conclusion, what I believe is that, if it weren
't for the world
1426 being so bad, it should be very clear to the political decision makers
1427 that the only way to go nowadays is free software for various reasons,
1428 but I have learnt that the only way that seems to work is bottom up.
</p
>
1432 > * Who should be interviewed with this questions in the future?
1434 That
's probably the hardest question of them all, as I do not know the
1435 community. However, I would be willing to do the following:
1437 <li
>Run an interview with a German headteacher who is very open to
1438 free software, and also prefers it, but cannot really use it because
1439 of the decision makers above;
1440 <li
>Run interviews with some kids, both with and without previous
1441 knowledge about free software
1443 If that is wanted, just let me know ;).

1459 his success story with installing Debian Edu at their school. This
1460 time I have been able to get some helpful comments from the creator of

1462 Germany a few years ago.

1469 freelance Open Source software developer and consultant.
</p

1471 <p

1472 from teaching, I

1484 <p

1485 coordinator for Skolelinux. We were looking for an all-in-one open

</li

1495 <li

</li
>
1502 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
1503 Edu?
</strong
></p
>
1506 <li
>Skolelinux is - as we had to learn - not easily upgradable to
1507 the next version. Opposed to its genuine Debian base, upgrading to
1508 a new version means a full new installation from scratch to get it
1509 working again reliably.
1511 <li
>Skolelinux is based on Debian/stable, and therefore always a
1512 little outdated in terms of program versions compared to Edubuntu or
1513 similar educational Linux distros, which rather use Debian/testing
1516 <li
>Skolelinux has some very self-opinionated and stubborn default
1517 configuration which in my opinion adds unnecessary complexity and is
1518 not always suitable for a schools needs, the preset network
1519 configuration is actually a core definition feature of Skolelinux
1520 and not easy to change, so schools sometimes have to change their
1521 network configuration to make it
"Skolelinux-compatible
".
1523 <li
>Some proposed extensions, which were made available as
1524 contribution, like secure examination mode and lecture material
1525 distribution and collection, were not accepted into the mainline
1526 Skolelinux development and are now not easy to maintain in the
1527 future because of Skolelinux somewhat undeterministic update
1530 <li
>Skolelinux has only a very tiny number of base developers
1531 compared to Debian.
</li
>
1535 <p
>For these reasons and experience from our project, I would now
1536 rather consider using plain Debian for schools next time, until
1537 Skolelinux is more closely integrated into Debian and becomes
1538 upgradeable without reinstallation.
</p

1540 <p
><strong
>Which free software do you use daily?
</strong
></p
>
1542 <p
>GNU/Linux with LXDE desktop, bash for interactive dialog and
1543 programming, texlive for documentation and correspondence,
1544 occasionally LibreOffice for document format conversion. Various
1545 programming languages for teaching.
</p

1547 <p
><strong
>Which strategy do you believe is the right one to use to
1548 get schools to use free software?
</strong

1550 <p
>Strong arguments are
</p

1554 <li
>Knowledge is free, and so should be methods and tools for
1555 teaching and learning.
</li
>
1557 <li
>Students can learn with and use the same software at school, at
1558 home, and at their working place without running into license or
1559 conversion problems.
</li
>
1561 <li
>Closed source or proprietary software hides knowledge rather
1562 than exposing it, and proprietary software vendors try to bind
1563 customers to certain products. But teachers need to teach
1564 science, not products.

>About Debian Edu and Skolelinux
</p
>
1699 <p
>Debian Edu, also known as Skolelinux, is a Linux distribution based
1700 on Debian providing an out-of-the box environment of a completely
1701 configured school network. Immediately after installation a school
1702 server running all services needed for a school network is set up just
1703 waiting for users and machines being added via GOsa², a comfortable
1704 Web-UI. A netbooting environment is prepared using PXE, so after
1705 initial installation of the main server from CD or USB stick all other
1706 machines can be installed via the network. The provided school server
1707 provides LDAP database and Kerberos authentication service,
1708 centralized home directories, DHCP server, web proxy and many other
1709 services. The desktop contains more than
60 educational software
1710 packages and more are available from the Debian archive, and schools
1711 can choose between KDE, Gnome, LXDE and Xfce desktop environment.
</p
>
1713 <p
>This is the seventh test release based on Debian Wheezy. Basically
1714 this is an updated and slightly improved version compared to the
1715 Squeeze release.
</p
>
1717 <p
>Notes for upgrades from Alpha Prereleases
</p
>
1719 <p
>Alpha based installations should reinstall or downgrade the
1720 versions of gosa and libpam-mklocaluser to the ones used in this beta
1721 release. Both alpha and beta0 based installations should reinstall or
1722 deal with gosa.conf manually; there are two options: (
1) Keep
1723 gosa.conf and edit this file as outlined on the mailing list. (
2)
1724 Accept the new version of gosa.conf and replace both contained admin
1725 password placeholders with the password hashes found in the old one
1726 (backup copy!). In both cases all users need to change their password
1727 to make sure a password is set for CIFS access to their home
1728 directory.

1781 replace both contained admin password placeholders with the password
1782 hashes found in the old one (backup copy!). In both cases every user
1783 need to change their their password to make sure a password is set for

1911 <p
><strong

</strong
></p
>
1915 <li
>Switched roaming workstation profiles from wicd to network-manager
1916 for network configuration, as wicd didn
't work any more.
</li
>
1917 <li
>Changed version numbers of patched gosa and libpam-mklocaluser
1918 packages to make sure our locally patched versions will be replaced
1919 by the official packages when they are released from Debian. Those
1920 installing alpha version need to reinstall or manually downgrade gosa

>
1937 <li
>Fixed code detecting and setting/loading hardware specific
1938 setup/firmware to work more robust out of the box.
</li
>
1939 <li

1940 install time instead of dynamically at run time. This avoid a crash
1941 with krb5-auth-dialog on diskless workstations without a DNS name.
</li
>
1942 <li
>Worked around misfeature in network-manager not calling the dhclient
1943 exit hooks, causing automatic proxy configuration and automatic host
1944 name setting at run time to work again.
</li
>
1945 <li
>Fixed feature setting the default Iceweasel start page from URL
1946 fetched from LDAP, to allow schools to set the global default by
1947 updating the dc=skole,dc=skolelinux,dc=no LDAP object.

2062 <li

</li

2063 <li
>Dropped menu-xdg from the KDE desktop option, to drop the Debian
2064 submenu. It was not included with Gnome, LXDE or Xfce, so this
2065 brings KDE in line with the others.
</li
>
2066 <li
>Dropped xdrawchem, xjig and xsok from our default installation as
2067 they don
't have a desktop menu entry and thus won
't show up in the
2068 menu now that menu-xdg was removed.
</li

2069 <li
>Removed the killer system to kill left behind processes on
2070 multi-user machines, as it was no longer able to understand when a
2071 X display was in use and killed the processes of the active users
2073 <li

2086 <li
>Made sure root and user passwords were not left behind in the
2087 debconf database after installation on Main Server installations.
</li
>
2088 <li
>Made Roaming Workstation dynamic setup more robust and added draft
2089 script setup-ad-client to hook a Roaming Workstation up to a
2090 Active Directory server instead of a Debian Edu Main Server.
</li

2091 <li

>In the
<a href=
"http://www.skolelinux.org/
">Debian Edu /
2139 Skolelinux
</a
> project, we include a post-installation test suite,
2140 which check that services are running, working, and return the
2141 expected results. It runs automatically just after the first boot on
2142 test installations (using test ISOs), but not on production
2143 installations (using non-test ISOs). It test that the LDAP service is
2144 operating, Kerberos is responding, DNS is replying, file systems are
2145 online resizable, etc, etc. And it check that the PXE service is
2146 configured, which is the topic of this post.
</p
>
2148 <p
>The last week I
've fixed the DVD and USB stick ISOs for our Debian
2149 Edu Wheezy release. These ISOs are supposed to be able to install a
2150 complete system without any Internet connection, but for that to
2151 happen all the needed packages need to be on them. Thanks to our test
2152 suite, I discovered that we had forgotten to adjust our PXE setup to
2153 cope with the new names and paths used by the netboot d-i packages.
2154 When Internet connectivity was available, the installer fall back to
2155 using wget to fetch d-i boot images, but when offline it require
2156 working packages to get it working. And the packages changed name
2157 from debian-installer-
6.0-netboot-$arch to
2158 debian-installer-
7.0-netboot-$arch, we no longer pulled in the
2159 packages during installation. Without our test suite, I suspect we
2160 would never have discovered this before release. Now it is fixed
2161 right after we got the ISOs operational.
</p
>
2163 <p
>Another by-product of the test suite is that we can ask system
2164 administrators with problems getting Debian Edu to work, to run the
2165 test suite using
<tt
>/usr/sbin/debian-edu-test-install
</tt
> and see if
2166 any errors are detected. This usually pinpoint the subsystem causing
2167 the problem.

2185 globe. And a while back, an enterprising young man showed up on
2186 <a href=
"irc://irc.debian.org/%

">our IRC channel
2187 #debian-edu
</a
> and started asking questions about how Debian Edu
2188 worked. We answered as good as we could, and even convinced him to
2189 help us with translations. And today I managed to get an interview
2190 with him, to learn more about him.

</strong
></p

2194 <p
>I
'm a
25 year old free software enthusiast, living in Romania,
2195 which is also my country of origin. Back in
2009, at a New Year
's Eve
2196 party, I had a very nice
<strike
>beer
</strike
> discussion with a
2197 friend, when we realized we have no organised Debian community in our
2198 country. A few days later, we put together the infrastructure for such
2199 community and even gathered a nice Debian-ish crowd. Since then, I
2200 began my quest as a free software hacker and activist and I am
2201 constantly trying to cover as much ground as possible on that
2204 <p
>A few years ago I founded a small web development company, which
2205 provided me the flexible schedule I needed so much for my
2206 activities. For the last
13 months, I have been the Technical Director
2207 of
<a href=
"http://ceata.org/
">Fundația Ceata
</a
>, which is a free
2208 software activist organisation endorsed by the FSF and the FSFE, and
2209 the only one we have in our country.
</p
>
2211 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
2212 project?
</strong
></p
>
2214 <p
>The idea of participating in the Debian Edu project was a surprise
2215 even to me, since I never used it before I began getting involved in
2216 it. This year I had a great opportunity to deliver a talk on
2217 educational software, and I knew immediately where to look. It was a
2218 love at first sight, since I was previously involved with some of the
2219 technologies the project incorporates, and I rapidly found a lot of
2220 ways to contribute.
</p
>
2222 <p
>My first contributions consisted in translating the installer and
2223 configuration dialogs, then I found some bugs to squash (I still
2224 haven
't fixed them yet though), and I even got my eyes on some other
2225 areas where I can prove myself helpful. Since the appetite for free
2226 software in my country is pretty low, I
'll be happy to be the first
2227 one around here advocating for the project
's adoption in educational
2228 environments, and maybe even get my hands dirty in creating a flavour
2229 for our own needs. I am not used to make very advanced plannings, so
2230 from now on, time will tell what I
'll be doing next, but I think I
2231 have a pretty consistent starting point.
</p

2233 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
2234 Edu?
</strong
></p
>
2236 <p
>Not a long time ago, I was in the position of configuring and
2237 maintaining a LDAP server on some Debian derivative, and I must say it
2238 took me a while. A long time ago, I was maintaining a bigger
2239 Samba-powered infrastructure, and I must say I spent quite a lot of
2240 time on it. I have similar stories about many of the services included
2241 with Skolelinux, and the main advantage I see about it is the
2242 out-of-the box availability of them, making it quite competitive when
2243 it comes to managing a school
's network, for example.
</p
>
2245 <p
>Of course, there is more to say about Skolelinux than the
2246 availability of the software included, its flexibility in various
2247 scenarios is something I can
't wait to experiment
"into the wild
" (I
2248 only played with virtual machines so far). And I am sure there is a
2249 lot more I haven
't discovered yet about it, being so new within the

><strong
>What do you see as the disadvantages of Skolelinux / Debian
2253 Edu?
</strong
></p
>
2255 <p
>As usual, when it comes to Debian Blends, I see as the biggest
2256 disadvantage the lack of a numerous team dedicated to the
2257 project. Every day I see the same names in the changelogs, and I have
2258 a constantly fear of the bus factor in this story. I
'd like to see
2259 Debian Edu advertised more as an entry point into the Debian
2260 ecosystem, especially amongst newcomers and students. IMHO there are a
2261 lot low-hanging fruits in terms of bug squashing, and enough
2262 opportunities to get the feeling of the Debian Project
's dynamics. Not
2263 to mention it
's a very fun blend to work on!
</p
>
2265 <p
>Derived from the previous statement, is the delay in catching up
2266 with the main Debian release and documentation. This is common though
2267 to all blends and derivatives, but it
's an issue we can all work
2270 <p
><strong
>Which free software do you use daily?
</strong
></p
>
2272 <p
>I can hardly imagine myself spending a day without Vim, since my
2273 daily routine covers writing code and hacking configuration files. I
2274 am a fan of the Awesome window manager (but I also like the
2275 Enlightenment project a lot!),
2276 <a href=
"http://www.claws-mail.org/
">Claws Mail

2277 use and very configurable behaviour. Recently I fell in love with
2278 <a href=
"https://launchpad.net/redshift

2279 get through the night without headaches. Of course, there is much more
2280 stuff in this bag, but I
'll need a blog on my own for doing this!

2283 get schools to use free software?
</strong

2285 <p
>Well, on this field, I cannot do much more than experiment right
2286 now. So, being far from having a recipe for success, I can only assume
2291 <li
>schools would like to get rid of proprietary software
</li
>
2293 <li
>students will love the openness of the system, and will want to
2294 experiment with it - maybe we need to harvest the native curiosity
2295 of teenagers more?
</li
>
2297 <li
>there is no
"right one
" when it comes to strategies, but it would
2298 be useful to have some success stories published somewhere, so
2299 other can get some inspiration from them (I know I
'd promote
2302 <li
>more active promotion - talks, conferences, even small school
2303 lectures can do magical things if they encounter at least one
2304 person interested. Who knows who that person might be? ;-)
</li
>
2308 <p
>I also see some problems in getting Skolelinux into schools; for
2309 example, in our country we have a great deal of corruption issues, so
2310 it might be hard(er) to fight against proprietary solutions. Also,
2311 people who relied on commercial software for all their lives, would be
2312 very hard to convert against their will.

2331 days vary quite a bit since I
'm involved in too many things. As I
'm
2332 getting older I
'm learning how to focus a bit more :)

2334 <p

'm also an Edubuntu contributor and I love when there are

2338 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
2339 project?
</strong
></p
>
2341 <p
>I
've been somewhat familiar with the project before, but I think my
2342 first direct exposure to the project was when I met Petter
2343 [Reinholdtsen] and Knut [Yrvin] at the Edubuntu summit in
2005 in
2344 London. They provided great feedback that helped the bootstrapping of
2345 Edubuntu. Back then Edubuntu (and even Ubuntu) was still very new and
2346 it was great getting input from people who have been around longer. I
2347 was also still very excitable and said yes to everything and to this
2348 day I have a big todo list backlog that I
'm catching up with. I think
2349 over the years the relationship between Edubuntu and Debian-Edu has
2350 been gradually improving, although I think there
's a lot that we could
2351 still improve on in terms of working together on packages. I
'm sure
2352 we
'll get there one day.
</p
>
2354 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
2355 Edu?
</strong
></p
>
2357 <p
>Debian itself already has so many advantages. I could go on about
2358 it for pages, but in essence I love that it
's a very honest project
2359 that puts its users first with no hidden agendas and also produces
2360 very high quality work.
</p
>
2362 <p
>I think the advantage of Debian Edu is that it makes many common
2363 set-up tasks simpler so that administrators can get up and running
2364 with a lot less effort and frustration. At the same time I think it
2365 helps to standardise installations in schools so that it
's easier for
2366 community members and commercial suppliers to support.

2368 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
2369 Edu?
</strong
></p
>
2371 <p
>I had to re-type this one a few times because I
'm trying to
2372 separate
"disadvantages
" from
"areas that need improvement
" (which is
2373 what I originally rambled on about)
</p
>
2375 <p
>The biggest disadvantage I can think of is lack of manpower. The
2376 project could do so much more if there were more good contributors. I
2377 think some of the problems are external too. Free software and free
2378 content in education is a no-brainer but it takes some time to catch
2379 on. When you
've been working with the same proprietary eco-system for
2380 years and have gotten used to it, it can be hard to adjust to some
2381 concepts in the free software world. It would be nice if there were
2382 more Debian Edu consultants across the world. I
'd love to be one
2383 myself but I
'm already so over-committed that it
's just not possible
2384 currently.
</p
>
2386 <p
>I think the best short-term solution to that large-scale problem is
2387 for schools to be pro-active and share their experiences and grow
2388 their skills in-house. I
'm often saddened to see how much money
2389 educational institutions spend on
3rd party solutions that they don
't
2390 have access to after the service has ended and they could
've gotten so
2391 much more value otherwise by being more self-sustainable and
2392 autonomous.
</p
>
2394 <p
><strong
>Which free software do you use daily?
</strong
></p
>
2396 <p
>My main laptop dual-boots between Debian and Windows
7. I was
2397 Windows free for years but started dual-booting again last year for
2398 some games which help me focus and relax (Starcraft II in
2399 particular). Gaming support on Linux is improving in leaps and bounds
2400 so I suppose I
'll soon be able to regain that disk space :)
</p
>
2402 <p
>Besides that I rely on Icedove, Chromium, Terminator, Byobu, irssi,
2403 git, Tomboy, KVM, VLC and LibreOffice. Recently I
've been torn on
2404 which desktop environment I like and I
'm taking some refuge in Xfce
2405 while I figure that out. I like tools that keep things simple. I enjoy
2406 Python and shell scripting. I went to an Arduino workshop recently and
2407 it was awesome seeing how easy and simple the IDE software was to get
2408 up and running in Debian compared to the users running Windows and OS
2411 <p
>I also use mc which some people frown upon slightly. I got used to
2412 using Norton Commander in the early
90's and it stuck (I think the
2413 people who sneer at it is just jealous that they don

2417 get schools to use free software?
</strong

2419 <p
>I think trying to force it is unproductive. I also think that in
2420 many cases it
's appropriate for schools to use non-free systems and I
2421 don
't think that there
's any particular moral or ethical problem with
2424 <p
>I do think though that free software can already solve so so many
2425 problems in educational institutions and it
's just a shame not taking
2426 advantage of that.
</p
>
2428 <p
>I also think that some curricula need serious review. For example,
2429 some areas of the world rely heavily on very specific versions of MS
2430 Office, teaching students to parrot menu items instead of learning the
2431 general concepts. I think that
's very unproductive because firstly, MS
2432 Office
's interface changes drastically every few years and on top of
2433 that it also locks in a generation to a product that might not be the
2434 best solution for them.
</p

2436 <p
>To answer your question, I believe that the right strategy is to
2437 educate and inform, giving someone the information they require to
2438 make a decision that would work for them.

2460 out-of-the box environment of a completely configured school
2461 network. Immediately after installation a school server running all
2462 services needed for a school network is set up just waiting for users

2464 environment is prepared using PXE, so after initial installation of

2602 interview last November. But the developers and translators are still
2603 pulling along to get the Wheezy based release out the door, and this
2604 time I managed to get an interview from one of the French translators
2605 in the project, Cédric Boutillier.

2607 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
2609 <p
>I am
34 year old. I live near Paris, France. I am an assistant
2610 professor in probability theory. I spend my daytime teaching
2611 mathematics at the university and doing fundamental research in
2612 probability in connexion with combinatorics and statistical physics.
</p
>
2614 <p
>I have been involved in the Debian project for a couple of years
2615 and became Debian Developer a few months ago. I am working on Ruby
2616 packaging, publicity and translation.
</p

2618 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
2619 project?
</strong
></p
>
2621 <p
>I came to the Debian Edu project after a call for translation of
2622 <a href=
"http://wiki.debian.org/DebianEdu/Documentation/Manuals
">the
2623 Debian Edu manual
</a
> for the release of Debian Edu Squeeze. Since
2624 then, I have been working on updating the French translation of the

>I had the opportunity to make an installation of Debian Edu in a
2628 virtual machine when I was preparing localised version of some screen
2629 shots for the manual. I was amazed to see it worked out of the box and
2630 how comprehensive the list of software installed by default was.
</p
>
2632 <p
>What amazed me was the complete network infrastructure directly
2633 ready to use, which can and the nice administration interface provided
2634 by
<a href=
"https://oss.gonicus.de/labs/gosa/
">GOsa²
</a
>. What pleased
2635 me also was the fact that among the software installed by default,
2636 there were many
"traditional
" educative software to learn languages,
2637 to count, to program... but also software to develop creativity and
2638 artistic skills with music (
<a href=
"http://ardour.org/
">Ardour
</a
>,
2639 <a href=
"http://audacity.sourceforge.net/
">Audacity
</a
>) and
2640 movies/animation (I was especially thinking of
2641 <a href=
"http://linuxstopmotion.sourceforge.net/
">Stopmotion
</a
>).
</p
>
2643 <p
>I am following the development of Debian Edu and am hanging out on
2644 <a href=
"irc://irc.debian.org/%

2645 Unfortunately, I don
't much time to get more involved in this
2646 beautiful project.
</p
>
2648 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
2649 Edu?
</strong
></p
>
2651 <p
>For me, the main advantages of Skolelinux/Debian Edu are its
2652 community of experts and its precise documentation, as well as the
2653 fact that it provides a solution ready to use.
</p
>
2655 <p
>I would add also the fact that it is based on the rock solid Debian
2656 distribution, which ensures stability and provides a huge collection
2657 of educational free software.
</p
>
2659 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
2660 Edu?
</strong
></p
>
2662 <p
>Maybe the lack of manpower to do lobbying on the
2663 project. Sometimes, people who need to take decisions concerning IT do
2664 not have all the elements to evaluate properly free software
2665 solutions. The fact that support by a company may be difficult to find
2666 is probably a problem if the school does not have IT personnel.
</p
>
2668 <p
>One can find support from a company by looking at
2669 <a href=
"http://wiki.debian.org/DebianEdu/Help/ProfessionalHelp
">the
2670 wiki dokumentation
</a
>, where some countries already have a number of
2671 companies providing support for Debian Edu, like Germany or
2672 Norway. This list is easy to find readily from the manual. However,
2673 for other countries, like France, the list is empty. I guess that
2674 consultants proposing support for Debian would be able to provide some
2675 support for Debian Edu as well.
</p
>
2677 <p
><strong
>Which free software do you use daily?
</strong
></p
>
2679 <p
>I am using the KDE Plasma Desktop. But the pieces of software I use
2680 most runs in a terminal: Mutt and OfflineIMAP for emails, latex for
2681 scientific documents, mpd for music. VIM is my editor of choice. I am
2682 also using the mathematical software
2683 <a href=
"http://www.scilab.org/en/scilab/about
">Scilab
</a
> and
2684 <a href=
"http://www.sagemath.org/index.html
">Sage
</a
> (built from
2685 source as not completely packaged for Debian, yet).
2687 <p
><strong
>Do you have any suggestions for teachers interested in
2688 using the free software in Debian to teach mathematics and
2689 statistics?
</strong
></p
>
2691 <p
>I do not have any
"nice
" recommendations for statistics. At our
2692 university, we use both
<a href=
"http://www.r-project.org/
">R

> and
2693 Scilab to teach statistics and probabilistic simulations. For
2694 geometry, there are nice programs:

2699 <a href=

2703 to discover symmetry groups (the so-called wallpapers and frieze

2884 kan få til med en datamaskin til NOK

2886 om et intervju.
</p

2888 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p

2890 <p
>Jeg heter Nirosan Thiyagalingam. Jeg er
24 år og studerer
2891 dataingeniør studiet ved Høgskolen i Sør Trøndelag. Interessen for
2892 data har siden ung alder vært tilstede og jeg har i tillegg alltid
2893 vært glad i å lære nye ting. Med teknologi som endres svært hurtig er
2894 det alltid noe nytt å lære. Noe som igjen har gjort det svært
2895 interessant å følge med på utviklingen. Jeg valgte dataingeniør
2896 studiet grunnet ønske om å lære enda mer om programmering og utvikling
2897 av store systemer.
</p

2899 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
2901 <p
>Skolelinux prosjektet hørte jeg først om i media. Men det var først
2902 når jeg skulle velge bacheloroppgave at jeg fattet mer interesse for
2903 prosjektet. Et enkelt søk på nettet førte meg til skolelinux sine
2904 hjemmesider. Informasjonen jeg fant der gjorde meg enda nysgjerrig og
2905 jeg valgte derfor en oppgave som gikk ut på å få en
2906 <a href=
"http://www.raspberrypi.org
">Raspberry PI
</a
>. Altså en
2907 ultra-billig datamaskin til å kjøre Debian Edu på lik linje med
2908 vanlige datamaskiner. I løpet av prosjektet ble det gjort mye
2909 forskning på nettet. Det var mye jeg måtte forstå rundt hvordan
2910 operativsystemet Linux fungerte før jeg kunne angripe
2911 problemet. Prøvde først å finne ut hvordan man kunne transformere en
2912 vanlig installasjon av Skolelinux til Raspberry PI, men dette var
2913 altfor vanskelig å jeg endte opp med mer spørsmål enn svar. Det ble
2914 videre opprettet kontakt med Skolelinux utviklere på IRC der jeg fikk
2915 diskutert hvilken retning jeg burde gå for å få til en fullverdig
2916 løsning. Det ble bestemt at jeg skulle gå for å først installere
2917 <a href=
"http://www.raspbian.org/
">Raspian
</a
>. Dette er et
2918 operativsystem basert på Debian spesiallaget for Raspberry Pi sin
2919 maskinvare. Nå som Debian var installert på datamaskinen gjenstod det
2920 å installere de nødvendige Skolelinux pakkene for å få til et
2921 fullverdig system. Disse pakkene ble installert manuelt i første
2922 omgang, men ble senere installert automatisk via et script som Petter
2923 Reinholdtsen laget. Dette scriptet er så enkel å bruke at man er i
2924 gang med installasjonen i løpet av bare
5 minutter. Ikke nok med det,
2925 alt skjer helt automatisk. Alt i alt er jeg veldig fornøyd med
2926 resultatet av installasjonsprosessen. Raspberry Pi er en veldig svak
2927 maskin og det merkes godt når man har installert Skolelinux på
2928 den. Video og
3D-rendering fungerer utrolig dårlig, men nettsurfing og
2929 kontorprogrammer fungerer godt. Det kan derfor konkluderes med at
2930 datamaskinen er egnet for enkle oppgaver.
2932 <p
>Jeg syns det er viktig påpeke at dette kun er startfasen av en slik
2933 løsning. På markedet finnes det nå maskiner som har bedre hardware enn
2934 Raspberry Pi. Det er store muligheter for at man kan klare å
2935 installere Skolelinux på disse også, og da forsvinner nok mest
2936 sannsynlig ytelsesproblemene med Video og
3D rendering også.
</p
>
2938 <p
>Det ble også prøvd med en løsning som gjorde at Raspberry Pi
2939 fungerte som en tynnklient. Denne løsningen hadde langt bedre ytelse
2940 med tanke på hastighet og brukeropplevelse. Men også her var video og
2941 3D rendering dårlig. Det ble brukt en liten Linux distribusjon kalt
2942 <a href=

">BerryTerminal
</a
> for å få til
2945 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
2947 <p
>Fordelen med Skolelinux er mange. At det er gratis er en stor
2948 fordel, men at det er så mange som er med på å utvikle det og
2949 vedlikeholde det er en enda større fordel. Allerede før jeg startet
2950 med prosjektet så jeg mange fordeler, og når jeg nærmet meg sluttfasen
2951 så jeg langt flere. At prosjektet skulle inneha en så høy kvalitet
2952 hadde jeg aldri trodd. En vanlig Skolelinux installasjon har de
2953 nødvendige programmene og funksjonen som både små og store skoler i
2954 tillegg til organisasjoner kan klare seg med. At prosjektet tilbyr en
2955 så komplett løsning er en kjempefordel. Installasjonen er knirkefri
2956 og det er svært enkelt å installere og komme i gang.

2958 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
2960 <p
>Ulempene jeg ser med prosjektet er ryddigheten av websidene. Selv
2961 om websidene er enkle og konsise er det allikevel ikke appellerende i
2962 like stor grad som for eksempel
2963 <a href=

2964 tilbyr, i tillegg til godt design og presentasjon, en nettbasert

2981 <p
>Strategien som burde brukes sett fra mine øyne er
2982 markedsføring. Jeg er sikker på at om flere skoler fikk et lite innsyn
2983 i hvor bra Skolelinux er så ville de ikke nølt med å gå over fra noe
2984 annet som koster de store summer. At skolelinux til de grader tilbyr
2985 en så komplett løsning bure komme frem. Enten via reklamekampanjer
2986 eller ved å sende ut folk til skoler for så å la skolenettverk
2987 ansvarlige få teste ut hvordan Skolelinux fungerer i praksis. Om det
2988 i tillegg ble utviklet gode websider og en emulator for å la brukere
2989 prøve operativsystemet ville nok dette ha styrket inntrykket
2990 betraktelig.

3011 lists and elsewhere, is the question on how to transform a Debian or
3012 Ubuntu installation into a Debian Edu installation. It isn
't very
3013 hard, and last week I wrote a script to replicate the steps done by
3014 the Debian Edu installer.

3018 in the debian-edu-config package, will go through these six steps and
3019 transform an existing Debian Wheezy or Ubuntu (untested) installation
3020 into a Debian Edu Workstation:
</p
>
3024 <li
>Add skolelinux related APT sources.
</li
>
3025 <li
>Create /etc/debian-edu/config with the wanted configuration.
</li

3026 <li
>Install debian-edu-install to load preseeding values and pull in
3027 our configuration.
</li

3028 <li
>Preseed debconf database with profile setup in
3029 /etc/debian-edu/config, and run tasksel to install packages
3030 according to the profile specified in the config above,
3031 overriding some of the Debian automation machinery.
</li

3032 <li
>Run debian-edu-cfengine-D installation to configure everything
3033 that could not be done using preseeding.
</li

3034 <li
>Ask for a reboot to enable all the configuration changes.

3038 <p
>There are some steps in the Debian Edu installation that can not be

3085 on Debian providing an out-of-the box environment of a completely
3086 configured school network. Immediatly after installation a school
3087 server running all services needed for a school network is set up just
3088 waiting for users and machines being added via GOsa², a comfortable
3089 Web-UI. A netbooting environment is prepared using PXE, so after
3090 initial installation of the main server from CD, DVD or USB stick all
3091 other machines can be installed via the network.

3178 i Narvikskolene og konstnaden ved å gå over til Windows. For litt

9 millioner
3188 for å gå over til Windows på skolene. I tillegg dokumenterer notatet
3189 at læreplanens krav oppfylles uten problemer ved bruk av Skolelinux.

3191 unødige utgifter på IT i skoleverket. :)

3377 the video show a walk-through of of the menu content, demonstration of
3378 a few programs and his view of our distribution.
</p

3380 <p
>There is also some really nice quotes (transcribed by me, might
3381 have heard wrong). While looking thought the Graphics menu:
</p

3384 "Basically everything you ever need in a school environment.
"
3387 <p
>And as a general evaluation of the entire distribution:
</p
>
3390 "So, yeah, a bit bloated. It kept all the Debian stuff in there, just
3391 to keep it nice and GNU. So, I do not want to go on about it, but
3392 lets give it
7 out of
10. I am not going to use it. That is because
3393 I am not deploying a school network. There may be some mythical
3394 feature to help you deploy Skolelinux on a school network.
"
3397 <p
>To bad he did not test the server profile, and discovered the PXE
3398 installation option. It make it possible to install only the main
3399 server from CD, and the rest of the machines via the net, and might be
3400 considered the mythical feature he talk about. :)
</p
>
3402 <p
>While looking through the menus, there is also this funny comment
3403 about the part of the K menu generated from the Debian menu subsystem:
3406 "[The K menu] have a special Debian section for software that no-one
3407 is going to look at, because it contain lots of junky stuff that you
3408 actually don
't need in the education distribution, but have just been
3409 included because it isn
't stripped out for some reason.
"
3412 <p
>I guess it is yet another argument for merging the Debian menu and
3413 Gnome/KDE desktop menu entries into
3414 <a href=

3415 consistent menu system

>Etter en lang pause og travle uker har jeg endelig klart å få
3528 samlet et nytt intervju med en av folkene i
3529 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet.
3530 Denne gang er det Helge Tore Høyland, en mangeårig bidragsyter på
3531 epostlistene og ellers i prosjektet.
</p
>
3533 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
3535 <p
>Eg er IT-konsulent/teknikker hjå eit firma i Steinkjer med navn
3536 <a href=
"http://unoit.no/
">Uno IT
</a
>. Uno IT er eit lite firma som
3537 drifter nettverk og maskiner for små og mellomstore firma
3538 Steinkjer-området. Per dags dato er me
2 ansatte. Min faglege bakgrunn
3539 er Fagbrev som it-teknikker, samt nokre fag innen nettverk- og
3540 server-drift frå HiST og NTNU. Dagleg arbeid består i oppsett av nye
3541 maskiner og hjelp til sluttbrukere, samt oppsett og vedlikehold av eit
3542 vidt spekter av fagsystemer ute hjå kunder. Erfaring med Skolelinux
3543 har eg hatt i forbindelse med drifting av
3544 <a href=
"http://www.bjorkly.no/
">Bjørkly skule
</a
>, ein privat
3545 grunnskule i Namsos-området. I dag har skulen
65 elever,
15 lærere,
1
3546 hovedserver og ca
60 klienter som kjører halvtjukt. Eg har bygd og
3547 driftet systemet sidan summaren
2006.
</p
>
3549 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
3551 <p
>Eg kom i kontakt med Skolelinux-prosjektet via ein artikkel i eit
3552 fagblad, som eg ikkje lenger hugsar namnet på. I og med at eg allereie
3553 hadde pusla med nettverk for ein annan skule, fatta eg straks
3554 interesse for prosjektet.
</p
>
3556 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
3558 <p
>Fordelane med Skolelinux er sentralisert administrasjon og svært
3559 mange gode verktøy «ut av boksen». Veldig kjekt å kunne drifte
60
3560 klientar med berre å «bry» seg med ein server. Levetid for systemets
3561 hardware er og ein veldig fin effekt. I tillegg kjem fordelar som økt
3562 sikkerhet og mindre lisenskostnader. Etter min erfaring er det og
3563 mykje mindre driftskostnader med eit slikt system enn konkurrerande
3564 system, pga enkelhet med sentralisert administrasjon. På grunn av at
3565 Skolelinux er basert på Debian er det òg svært stabilt.
</p
>
3567 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
3569 <p
>Ulemper er mangel på vilje til å følge standarer ute i markedet,
3570 som fører til mangel på støtte til nokre mykje brukte ting. Flash og
3571 Java er typiske eksempel. Sidan Debian satsar på stabilitet framfor å
3572 ha nyeste pakke av eit program, kan ein i nokre tilfeller kome borti
3573 at program vert «for gamle». Det er spesielt nettlesaren som er
3574 utsett. Mangel på vilje til å utvikle pedagogisk programvare, i Noreg,
3575 for «alle» platformer fører òg til noko hovudbry.
</p
>
3577 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
3579 <p
>Til dagleg bruker eg svært mange forskjellige «fri programvare»
3580 program. Firefox, Thunderbird, Freecommander, ImgBurn, Clonezilla,
3581 OCS inventory, Icinga, Skolelinux, SystemRescueCD og mykje meir.
</p
>
3583 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
3584 skoler til å ta i bruk fri programvare?
</strong
></p
>
3586 <p
>Strategisk må ein fokusere på at sluttbruker eigentleg ikkje er så
3587 fokusert på at det er fri programvare men at det skal «berre fungere».
3588 Gjer det enkelt å bruker og ikkje minst å administrere. For Skolelinux
3589 sin del må ein få eit betre fokus på overganger. Utbytting av servere
3590 må gå meir automatisk, import og eksport av brukerbase og maskinbase
3591 med meir må kunne gå enkelt og oppgradering til neste versjon må bli
3592 mykje meir automatisk og gjennomtesta. Ein må unngå at ein må sette
3593 opp frå start når ein byter ut ein server eller oppgraderer til neste
3594 versjon. For å få Skolelinux til å bli eit betre alternativ for skular
3595 må ein ha fokus på nettlesaren. Denne må bli «up to date» og støtte
3596 dei protokollar og tillegg som vert brukt av forlag med meir. Etter
3597 kvart som meir og meir blir flytta ut i «skya» vert dette viktigare og
3598 viktigare. Ein kunne ynskje og jobbe for at forlag med fleire tar i
3599 bruk opne standarer, men inntil det skjer, må systemet kunne brukast
3600 mot desse fagsystema.
</p
>
3602 <p
>For meg har prosjektet med Skolelinux vore ein svært artig og
3603 lærerik prosess. Miljøet rundt er ikkje enormt stort, dog stort nok,
3604 men det er svært hjelpevillig og engasjert.

3618 present. As the Debian Edu / Skolelinux project is very short on
3619 funding these days, and thus lack the money to do regular developer
3620 gatherings, this donation was most welcome. One developer gathering
3621 cost around NOK
15&nbsp;

3622 development pace we want. Thus, I hope their example this year is
3623 followed by many others. :)

3641 interesting, as I am involved with several organizations where
3642 accounting is an issue, and I have not really become too friendly with
3643 the different web based systems we use. I find it hard to find what I
3644 look for in the menus and even harder try to get sensible data out of
3645 the systems. Ledger seem different. The accounting data is kept in
3646 text files that can be stored in a version control system, and there
3648 are at least
<a href=

3698 community. I am running short on people willing to be interviewed, so
3699 if you know about someone I should interview, Please send me an email.
3700 After asking for many months, I finally managed to lure another one of
3701 the people behind the German
3702 "<a href=
"http://wiki.it-zukunft-schule.de/
">IT-Zukunft Schule

3703 project out from maternity leave to conduct an interview. Give a warm
3704 welcome to Angela Fuß. :)
</p

3706 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
3708 <p
>I am a
39-year-old woman living in the very north of Germany near
3709 Denmark. I live in a patchwork family with
"my man
" Mike Gabriel, my
3710 two daughters, Mikes daughter and Mikes and my rather newborn son.
3712 <p
>At the moment - because of our little baby - I am spending most of
3713 the day by being a caring and organising mom for all the kids.
3714 Besides that I am really involved into and occupied with several inner
3715 growth processes: New born souls always bring the whole familiar
3716 system into movement and that needs time and focus ;-). We are also
3717 in the middle of buying a house and moving to it.
</p
>
3719 <p
>In
2013 I will work again in my job in a German foundation for
3720 nature conservation. I am doing public relation work there. Besides
3721 that - and that is the connection to Skolelinux / Debian Edu - I am
3722 working in our own school project
"IT-Zukunft Schule
" in North
3723 Germany. I am responsible for the quality assurance, the customer
3724 relationship management and the communication processes in the
3727 <p
>Since
2001 I constantly have been training myself in communication
3728 and leadership. Besides that I am a forester, a landscaping gardener
3729 and a yoga teacher.
</p
>
3731 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
3732 project?
</strong
></p
>
3734 <p
>I fell in love with Mike ;-).
</p
>
3736 <p
>Very soon after getting to know him I was completely enrolled into
3737 Free Software. At this time Mike did IT-services for one newly
3738 founded school in Kiel. Other schools in Kiel needed concepts for
3739 their IT environment. Often when Mike came home from working at the
3740 newly founded school I found myself listening to his complaints about
3741 several points where the communication with the schools head or the
3742 teachers did not work. So we were clear that he would not work for
3743 one more school if we did not set up a structure for communication
3744 between him, the schools head, the teachers, the students and the
3747 <p
>Together with our friend and hardware supplier Andreas Buchholz we
3748 started to get an overview of free software solutions suitable for
3749 schools. One day before Christmas
2010 Mike and I had a date with Kurt
3750 Gramlich in Gütersloh. As Kurt and I are really interested in building
3751 networks of people and in being in communication we dived into
3752 Skolelinux and brought it to the first grammar schools in Northern
3755 <p

>
3759 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
3760 Edu?
</strong
></p
>
3762 <p
>First I have to say: I cannot answer this question technically. My
3763 answer comes rather from a social point of view.
</p
>
3765 <p
>The biggest advantage of Skolelinux / Debian Edu I see is the large
3766 and strong international community of Debian Developers in the
3767 background which is very alive and connected over mailinglists, blogs
3768 and meetings. My constant feeling for the Debian Community is: If
3769 something does not work they will somehow fix it. All is well
3770 ;-). This is of course a user experience. What I also get as a big
3771 advantage of Skolelinux / Debian Edu is that everybody who uses it and
3772 works with it can also contribute to it - that includes students,
3773 teachers, parents...
</p
>
3775 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
3776 Edu?
</strong
></p
>
3778 <p
>I will answer this question relating to the internal structure of
3779 Skolelinux / Debian Edu.
</p
>
3781 <p
>What I see as a major disadvantage is that there is a gap between
3782 the group of developers for Debian Edu and the people who make the
3783 marketing, that means the people that bring Skolelinux to the
3784 schools. There is a lack of communication between these two groups and
3785 I think that does not really work for Skolelinux / Debian Edu.
</p
>
3787 <p
>Further I appreciate that Skolelinux / Debian Edu is known as a
3788 do-ocracy. Nevertheless I keep asking myself if at some points a
3789 democracy or some kind of hierarchical project structure would be good
3790 and helpful. I am also missing some kind of contact between the
3791 Skolelinux / Debian Edu communities in Europe or on an international
3792 level. I think it would be good if there was more sharing between the
3793 different countries using Skolelinux / Debian Edu.
</p
>
3795 <p
><strong
>Which free software do you use daily?
</strong
></p
>
3797 <p
>On my laptop I am still using an Ubuntu
10.04 with a Gnome Desktop
3798 on. As applications I use Openoffice.org, Gedit, Firefox, Pidgin,
3799 LaTeX and GnuCash. For mails I am using Horde. And I am really fond of
3800 my N900 running with Maemo.
</p
>
3802 <p
><strong
>Which strategy do you believe is the right one to use to
3803 get schools to use free software?
</strong
></p
>
3805 <p
>I am really convinced that in our school project
"IT-Zukunft
3806 Schule
" we have developed (and keep developing) a great way to get
3807 schools to use Free Software. We have written a detailed concept for
3808 that so I cannot explain the whole thing here. But in a nutshell the
3809 strategy has three crucial pillars:
</p
>
3813 <li
>We really take time to get what sort of stories, questions and
3814 concerns the schools head and the teachers have about using different
3815 kinds of IT and we take time to enrol them into Free Software.
</li
>
3817 <li
>Our solution for schools is never just technical. In the centre
3818 are always the people who are going to use the software. From the very
3819 beginning of the planning for a school, we tell the schools head that
3820 they are paying us not only for a technical solution for their school,
3821 they also pay us for leading all the communication processes
3822 needed. If they do not want that, we are not working with them because
3823 we cannot give a guarantee for the quality of our work then.
</li
>
3825 <li
>Another focus lies in the training of teachers and students in
3826 co-administrating the IT-System at their school. They start getting in
3827 contact with the Skolelinux / Debian Edu community and they get the
3828 offer to become more and more independent from us.

</p

3851 <p
>I sommer (
2012-
07-
23) hadde Fremover et oppslag om at Narvik
3852 kommune hadde spart mellom
10 og
20 millioner kroner de siste årene på
3853 å bruke Skolelinux på sine skoler. Harstad har også tatt i bruk
3854 Skolelinux på alle sine skoler. Som tidligere Ballangsværing gledet
3855 det meg stort å se at skoleløsningen vi har utviklet siden
2001 tas i
3856 bruk i området der jeg vokste opp, og dermed bidrar til en bedre og
3857 billigere skolehverdag.
</p
>
3859 <p
>Skolelinux er en komplett IT-løsning for elevnettverket på en
3860 skole, med både nettverkstjenester og løsning for elevmaskiner med
3861 pedagogisk programvare, som tillater en å øke levetiden på en
3862 datamaskin i skolen med mange år. En undersøkelse publisert i mars
3863 2012 viste at de
56 norske skolene som har offentliggjort at de bruker
3864 Skolelinux eller annen Linuxutgave hadde
36% større PC-tetthet enn
3865 landsgjennomsnittet, når en ser på tall rapportert til Grunnskolens
3866 Informasjonssystem. I følge Paul Reidar Løsnesløkken, IKT-konsulent i
3867 Nord-Odal, fungerer datamaskiner godt til de er
8 til
10 år gamle.
</p
>
3869 <p
>I høst (
2012-
09-
29) fortalte Fremover hvordan Ballangen kommune har
3870 opparbeidet seg
20 millioner i underskudd og nok havner på Robek-lista
3871 fra nyttår. Kanskje Ballangen også burde ta i bruk Skolelinux for å
3872 spare penger? Hvis kommunen mangler kompetanse lokalt på Linux finnes
3873 det kommersielle selskaper som tilbyr driftstjenester rundt
3874 Skolelinux, og jeg bør vel avsløre at jeg selv er involvert i et av
3875 dem, Skolelinux Drift AS. Kommunen kan dermed få hjelp hvis de ikke
3876 ønsker å bygge opp egen kompetanse.

4082 <p

4083 very generous for help and hints. Chat help is crucial, together with
4084 the mailing list. Second. With Skolelinux you get an already well
4085 engineered platform and you don
't have to start to build up your PDC
4086 and your clients from GNU/scratch; I
've already done this once and I
4087 can tell it, it is hard. Third, since Skolelinux is a standard
4088 platform, it is way easier to educate other IT people and even if the
4089 head IT is sick another one could pick up the task without too much

4097 there are many reasons that force for another choice. For example the
4098 need of new drivers for new PC, or the need for a specific OS for some
4099 devices that have specific software packages for another specific

4151 <p
>Artikkelen med tittelen
"Narvik kommune bruker gratisprogram i
4152 skolen - Har spart millioner
", forteller om hvordan bruken av
4153 Skolelinux er en stor suksess i Narvik siden det ble tatt i bruk i
4154 2004. Her er noen fine sitater:
</p
>
4157 "- Skolelinux har spart kommunen for store pengesummer, millionbeløp,
4158 som de heller kan bruke på andre ting, sier IKT-konsulent Viggo
4162 <p
>Avisen forteller at de har fått tilgang til beregninger som viser
4163 at Narvik kommune har spart noe mellom
10 og
20 millioner kroner de
4164 siste
8 årene på å bruke Skolelinux, og fortsetter:
</p
>
4168 "Regnestykket tar høyde for sparte kostnader til lisenser som medfølger
4169 de alternative operativsystemene, lavere driftskostnader og lengre
4170 levetid på datautstyret. Totalt har Narvikskolen en maskinpark på
4171 1600 maskiner fordelt på de
11 skolene fra Skjomen i sør til Bjerkvik
4176 <p
>Viggo Fedreheim sier dette om hvor noe av gevinsten kommer fra:
</p
>
4179 "- Vi kan gjenbruke gamle maskiner i skolen som er for dårlig andre
4180 steder i kommunen der de ikke bruker Skolelinux. Levetiden på en
4181 datamaskin blir
3-
5 år lenger med Skolelinux. Vi kaller det for
4182 grønn IT, miljøvennlig IT.
"
4185 <p
>Her er det mulighet for flere kommuner å få et godt IT-system på
4186 skolene, hvis de er villige til å forsøke. De som ikke har kompetanse

'm a
44 year old country guy that have been working
12 years at
4263 the same school as
50% IT-manager and
50% Teacher. My educational
4264 background is fil.kand in history and religious beliefs, an exam as a
4265 "folkhighschool
" teacher, that is, for teaching grownups. In
4266 Norwegian I believe it
's called
"Vuxenupplaring
". I also have a master
4267 in
"Technology and social change

'm not really a tech guy, I
4268 just like to study how humans and technology interact and that is my
4269 perspective when working with IT.
</p
>
4271 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4272 project?
</strong
></p
>
4274 I have followed the Skolelinux project for quite some time by
4275 now. Earlier I tested out the K12-LTSP project, which we used for some
4276 time, but I really like the idea of having a distribution aimed to be
4277 a complete solution for schools with necessary tools integrated. When
4278 K12-LTSP abandoned that idea some years ago, I started to look more
4279 seriously into Skolelinux instead.
4281 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4282 Edu?
</strong
></p
>
4284 The big point of Skolelinux to me is that it is a complete
4285 distribution, ready to install. It has LDAP-support, MS Windows
4286 integration tools and so forth already configured, saving an
4287 administrator a lot of time and headache. We were using another Linux
4288 based thin-client system called Thinlinc, that has served us very
4289 well. But that Skolelinux is based on VNC and LTSP, to me, is better
4290 when it comes to the kind of multimedia used in schools. That is
4291 showing videos from Youtube or educational TV. It is also easier to
4292 mix thin clients with workstations, since the user settings will be the
4293 same. In our VNC-based solution you had to
"beat around the bush
" by
4294 setting up a second, hidden, home-directory for user settings for the
4295 workstations, because they will be different from the ones used on the
4296 thin clients. Skolelinux support for diskless workstations are very
4297 convenient since a school today often need to use a class room
4298 projector showing videos in full screen. That is easily done with a
4299 small integrated media computer running as a diskless workstation. You
4300 have only two installs to update and configure. One for the thin
4301 clients and one for the workstations. Also saving a lot of time. Our
4302 old system was also based on Redhat and CentOS. They are both very
4303 nice distributions, but they are sometimes painfully slow when it
4304 comes to updating multimedia support and multimedia programs (even
4305 such as Gimp), leaving us with a bit
"oldish
" applications. Debian is
4308 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
4309 Edu?
</strong
></p
>
4311 <p
>Debian is a bit too quick when it comes to updating. As an example
4312 we use old HP terminals as thinclients, and two times already this
4313 year (
2012) the updates you get from the repositories has stopped
4314 sound from working with them. It
's a kernel/ALSA issue. So you have
4315 to be more careful properly testing the updates before you run them in
4316 a production environment. This has never happened with CentOS.
</p
>
4318 <p
>I also would like to be able to set my own domain-settings at
4319 install time. In Skolelinux they are kind of hard coded into the
4320 distribution, when it comes to LDAP and at least samba integration.
4321 That is more a cosmetic/translation issue, and not a real problem.
4322 Running MS Windows applications within the Skolelinux environment needs
4323 to be better supported. That is, running them seamlessly via RDP, and
4324 support for single-sign on. That will make the transition to free
4325 software easier, because you can keep the applications you really
4326 need. No support will make it impossible if you work in a school where
4327 some applications can
't be open source. As for us we really need to
4328 run Adobe InDesign in our journalist classes. We run a journalist
4329 education, and is one of the very few non university ones that is ok:d
4330 by Svenska journalistförbundet (Swedish journalist association). Our
4331 education gives the pupils the right of membership there, once they
4332 are done. This is important if you want to get a job.
</p
>
4334 <p
>Adobe InDesign is the program most commonly used in newspapers and
4335 magazines. We used Quark Express before, but they seem to loose there
4336 market to Adobe. The only
"equivalent
" to InDesign in the opensource
4337 world is Scribus, and its not advanced enough. At least not according
4338 to the teacher. I think it would be possible to use it, because they
4339 are not supposed to learn a program, they are supposed to learn how to
4340 edit and compile a newspaper. But politically at our school we are not
4341 there yet. And Scribus lacks a lot of things you find i InDesign.
</p
>
4343 <p
>We used even a windows program for sound editing when it comes to
4344 the radio-journalist part. The year to come we are going to try
4345 Audacity. That software has the same kind of limitations compared to
4346 Adobe Audition, but that teacher is a bit more open minded. We have
4347 tried Ardour also, but that instead is more like a music studio
4348 program, not intended for the kind of editing taking place in a radio
4349 studio. Its way to complex and the GUI is to scattered when you only
4350 want to cut, make pass-overs, add extra channels and normalise. Those
4351 things you can do in Audacity, but its not as easy as in Audition. You
4352 have to do more things manually with envelopes, and that is a bit old
4353 fashion and timewasting. Its also harder to cut and move sound from
4354 one channel to another, which is a thing that you do frequently
4355 because you often find yourself needing to rearrange parts of the
4356 sound file.
</p
>
4358 <p
>So, I am not sure we will succeed in replacing even Audition, but we
4359 will try. The problem is the students have certain expectations when
4360 they start an education towards a profession. So the programs has to
4361 look and feel professional. Good thing with radio, there are many
4362 programs out there, that radio studios use, so its not as standardised
4363 as Newspaper editing. That means, it does not really matter what
4364 program they learn, because once they start working they still have to
4365 learn the program the studio uses, so instead focus has to be to learn
4366 the editing part without to much focus on a specific software.

4370 <p
>Myself I
'm running Linux Mint, or Ubuntu these days. I use almost
4371 only open source software, and preferably Linux based. When it comes
4372 to most used applications its OpenOffice, and Firefox (of course ;)
4375 <p
><strong
>Which strategy do you believe is the right one to use to
4376 get schools to use free software?
</strong
></p
>
4378 <p
>To get schools to use free software there has to be good open
4379 source software that are windows based, to ease the transition. But
4380 it
's also very important that the multimedia support is working
4381 flawlessly. The problems with Youtube, Twitter, Facebook and whatever
4382 will create problems when it comes to both teachers and
4383 students. Economy are also important for schools, so using thin
4384 clients, as long as they have good multimedia support, is a very good
4385 idea. It
's also important that the open source software works even for
4386 the administration. It
's hard to convince the teachers to stick with
4387 open source, if the principal has to run Windows. It also creates a
4388 problem if some classes has to use Windows for there tasks, since that
4389 will create a difference in
"status
" between classes, so a good
4390 support for running windows applications via the thin client (Linux)
4391 desktop is essential. At least at our school, where we have mixed
4392 level of educations, from high-school to journalist-school.

4628 <p
>Jeg heter Markus Gamenius og er
40 år. Utdannet biolog med ymse
4629 fag på siden. Har jobbet som lærer der jeg var driftsansvarlig på
4630 Ulsrud VGS i Oslo. Senere eide og jobbet jeg flere år i Linuxlabs AS,
4631 som jeg solgte til Redpill Linpro AS (den gangen Linpro AS). I dag
4632 jobber jeg med ulike investeringer, hovedsaklig i eiendom, men også i
4633 en del ulike IT-relaterte bedrifter.

4637 <p
>Fruen og jeg dro på en lengre seiltur i
2000, der jeg måtte ha
"noe
4638 å gjøre
" under hjemturen over Atlanteren. Jeg kjøpte et par bøker om
4639 Linux i en bokhandel i New York og ble veldig fascinert. Etter
4640 hjemkomsten begynte jeg å jobbe på Ulsrud VGS, som naturfagslærer, men
4641 som IT-interessert ble jeg fort en del av den nye IT-satsningen som
4642 skulle løfte Ulsrud og gi skolen en bedre rykte. Vi hadde ganske
4643 mange maskiner, som gikk på Win98 og to servere som ble oppgradert til
4644 Win2000. Systemene var ustabil og dårlige. På leting etter noe
4645 bedre, uten å knekke ryggen økonomisk, kom jeg over
"Linux i Skolen
"
4646 og Skolelinux. Jeg tok kontakt med miljøet og en gjeng møtte opp på
4647 skolen, der vi gjorde en liten testinstallasjon. Etter et par år var
4648 ryggraden på skolen Linux (Skolelinux) og vi hadde flere hundre
4649 maskiner, både tynne klienter (gamle og nye), bærbare (Debian) og noen
4650 stasjonære (Win2000). På et tidspunkt var Ulsrud den råeste IT-skolen
4651 og det irriterte skolesjefen i Oslo, da de satset hardt på

>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
4656 <p
>Det som gjorde at vi fikk inn Skolelinux var ene og alene
4657 økonomiske. Det faktum at vi slapp å kjøpe masse nye lisenser og at
4658 vi kunne bruke gammel hardware. Alt i alt gjorde dette at vi sparte
4659 mye, men i stede for å bruke mindre på IT brukte vi det vi sparte på å
4660 skaffe mer hardware og på den måten gi det beste tilbudet i landet til
4661 våre elever. For oss som driftet var det himmel å ha et system som
4662 gikk å administrere sentralt og effektivt. Det var heller ikke så
4663 dumt at vi kunne
"låse
" maskinene mer effektivt enn vi kunne med
4664 Microsoft Windows, slik at vi slapp mye feil og problemer som ble
4665 forårsaket av
"kreative
" elever.

4667 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
4669 <p
>Det vi slet med var mangelen av en del programmer lærerne ville ha.
4670 Husker ikke alle, men det var et knippe med pedagogiske programmer de
4671 ikke fikk. I dag tror jeg det problemet er langt mindre da det meste
4672 av disse kjøres gjennom nettleseren.

4676 <p
>Jeg bruker mye Apple i dag og er ikke så stolt av det, men jeg har
4677 både OpenOffice, Firefox og en del andre programmer på den bærbare.
4678 Firefox brukes mest av disse. På Apple-serveren hjemme bruker jeg
4679 HandBrake mye, og jeg har installert OpenWRT på flere av
4680 basestasjonene både hjemme og på jobben. I tillegg til det har jeg i
4681 flere år finansiert et prosjekt som heter
4682 <a href=
"http://www.found.no/
">Found IT
</a
>. Dette er et prosjekt der
4683 vi lager et rammeverk for søk, der alt vi bruker fri programvare. Det
4684 er Alex Brasetvik som er daglig leder i Found IT.

4687 skoler til å ta i bruk fri programvare?
</strong

4689 <p
>Når det gjelder IT og skole er fortsatt økonomi veldig viktig. Så
4690 man må oppfylle minimumskravene (ikke være best, men bra nok) og selge
4691 seg inn på hvor mye man sparer. Det betyr selvsagt at man sparer på
4692 lisenser, men også på driftsinnsats. Men nå når jeg ikke er en aktiv
4693 del av miljøet lenger hører jeg nesten ingen ting om fri programvare.
4694 Jeg stiller meg da spørsmålet om det har blitt stille rundt miljøet,
4695 eller om jeg kun så det tydeligere før når jeg var aktiv? Uansett er
4696 det for stille rundt Skolelinux-prosjektet nå.

've been too busy at home, but finally I found time to wrap up
4706 another interview with the people behind
4707 <a href=
"http://www.skolelinux.org/
">Debian Edu and Skolelinux
</a
>.
4708 This time we get to know José Luis Redrejo Rodríguez, one of our great
4709 helpers from Spain. His effort was the reason we added support for
4710 several desktop types (KDE, Gnome and most recently LXDE) in Debian
4711 Edu, and have all of these available in the recently published
4712 <a href=
"http://www.debian.org/News/

4713 Squeeze

> version.
</p
>
4715 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
4717 <p
>I
'm a father, teacher and engineer who is working for the Education
4718 ministry of the Region of Extremadura (Spain) in the implementation of
4719 ICT in schools
</p
>
4721 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4722 project?
</strong
></p
>
4724 <p
>At
2006, I verified that both, we in Extremadura and Skolelinux
4725 project, had been working in parallel for some years, doing very
4726 similar things, using very similar tools and with similar targets, so
4727 I decided it was time to join forces as much as possible.
</p
>
4729 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4730 Edu?
</strong
></p
>
4732 <p
>A community of highly skilled experts working together, with a
4733 really open schema of collaboration and work. I really love the
4734 concepts of Do-ocracy and Merit-ocracy and the way these concepts are
4735 been used everyday inside Debian Edu.
</p
>
4737 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
4738 Edu?
</strong
></p
>
4740 <p
>Sometimes the differences in the implementations, laws or
4741 economical and technical resources in the different countries don
't
4742 allow us to agree in the same solution for all of us, and several
4743 approaches are needed, what is a waste of effort. Also, there is a
4744 lack of more man power to be able to follow the fast evolution of the
4745 technologies in school.
</p
>
4747 <p
><strong
>Which free software do you use daily?
</strong
></p
>
4749 <p
>Debian, of course, and due to my kind of job I am most of my time
4750 between Iceweasel,
<a href=
"http://www.geany.org/
">Geany
</a
> and
4751 <a href=
"http://www.ohloh.net/p/gnome-terminator
">Terminator
</a
>.
</p
>
4753 <p
><strong
>Which strategy do you believe is the right one to use to
4754 get schools to use free software?
</strong
></p
>
4756 <p
>I think there is not a single strategy because there are very
4757 different scenarios: schools with mixed proprietary and free
4758 environments, schools using only workstations, other schools using
4759 laptops, netbooks, tablets, interactive white-boards, etc.
</p
>
4761 <p
>Also the range of ages of the students is very broad and you can
4762 not use the same solutions for primary schools and secondary or even
4763 universities. So different strategies are needed.
</p
>
4765 <p
>But, looking at these differences, and looking back to the things
4766 we
've done and implemented, and the places were we have spent most of
4767 our forces, I think we should focus as much as possible in free
4768 multi-platform environments, using only standards tools, and moving
4769 more and more to Internet or network solutions that could be deployed
4770 using wireless. I think we
'll see more and more personal devices in
4771 the schools, devices the students and teachers will take home with
4772 them, so the solutions must be able to be taken at home and continue
4773 working there.

">Debian Edu
4784 based on Squeeze
</a
>, I came across some issues that should be
4785 addressed in the Wheezy release. I finally found time to wrap up my
4786 notes and provide quick summary of what I found, with a bit
4787 explanation.
</p
>
4791 <li
>We need to rewrite our package installation framework, as tasksel
4792 changed from using tasksel tasks to using meta packages (aka packages
4793 with dependencies like our education-* packages), and our installation
4794 system depend on tasksel tasks in
4795 /usr/share/tasksel/debian-edu-tasks.desc for package
4796 installation.
</li
>
4798 <li
>Enable Kerberos login for more services. Now with the Kerberos
4799 foundation in place, we should use it to get single sign on with more
4800 services, and avoiding unneeded password / login questions. We should
4801 at least try to enable it for these services:
4804 <li
>CUPS for admins to add/configure printers and users when using
4806 <li
>Nagios for admins checking the system status.
</li
>
4807 <li
>GOsa for admins updating LDAP and users changing their passwords.
</li
>
4808 <li
>LDAP for admins updating LDAP.
</li
>
4809 <li
>Squid for users when exam mode / filtering is active.
</li
>
4810 <li
>ssh for admins and users to save a password prompt.
</li
>
4812 </ul
></li
>
4814 <li
>When we move GOsa to use Kerberos instead of LDAP bind to
4815 authenticate users, we should try to block or at least limit access to
4816 use LDAP bind for authentication, to ensure Kerberos is used when it
4817 is intended, and nothing fall back to using the less safe LDAP bind
</li
>
4819 <li
>Merge debian-edu-config and debian-edu-install. The split made
4820 sense when d-e-install did a lot more, but these days it is just an
4821 inconvenience when we update the debconf preseeding values.
</li
>
4823 <li
>Fix partman-auto to allow us to abort the installation before
4824 touching the disk if the disk is too small. This is
4825 <a href=
"http://bugs.debian.org/
653305">BTS report #
653305</a
> and the
4826 d-i developers are fine with the patch and someone just need to apply
4827 it and upload. After this is done we need to adjust
4828 debian-edu-install to use this new hook.
</li
>
4830 <li
>Adjust to new LTSP framework (boot time config instead of install
4831 time config). LTSP changed its design, and our hooks to install
4832 packages and update the configuration is most likely not going to work
4835 <li
>Consider switching to NBD instead of NFS for LTSP root, to allow
4836 the Kernel to cache files in its normal file cache, possibly speeding
4837 up KDE login on slow networks.
</li
>
4839 <li
>Make it possible to create expired user passwords that need to
4840 change on first login. This is useful when handing out password on
4841 paper, to make sure only the user know the password. This require
4842 fixes to the PAM handling of kdm and gdm.
</li
>
4844 <li
>Make GUI for adding new machines automatically from sitesummary.
4845 The current command line script is not very friendly to people most
4846 familiar with GUIs. This should probably be integrated into GOsa to
4847 have it available where the admin will be looking for it..
</li
>
4849 <li
>We should find way for Nagios to check that the DHCP service
4850 actually is working (as in handling out IP addresses). None of the
4851 Nagios checks I have found so far have been working for me.
</li
>
4853 <li
>We should switch from libpam-nss-ldapd to sssd for all profiles
4854 using LDAP, and not only on for roaming workstations, to have less
4855 packages to configure and consistent setup across all profiles.
</li
>
4857 <li
>We should configure Kerberos to update LDAP and Samba password
4858 when changing password using the Kerberos protocol. The hook was
4859 requested in
<a href=
"http://bugs.debian.org/
588968">BTS report
4860 #
588968</a
> and is now available in Wheezy. We might need to write a
4861 MIT Kerberos plugin in C to get this.
</li
>
4863 <li
>We should clean up the set of applications installed by default.
4866 <li
>reduce the number of chemistry visualisers
</li
>
4867 <li
>consider dropping xpaint
</li
>
4868 <li
>and probably more?
</li
>
4869 </ul
></li
>
4871 <li
>Some hardware need external firmware to work properly. This is
4872 mostly the case for WiFi network cards, but there are some other
4873 examples too. For popular laptops to work out of the box, such
4874 firmware need to be installed from non-free, and we should provide
4875 some GUI to do this. Ubuntu already have this implemented, and we
4876 could consider using their packages. At the moment we have some
4877 command line script to do this (one for the running system, another
4878 for the LTSP chroot).
</li
>
4881 <li

4896 implement a way to easily enable this for the schools that want it,

2010, Mike Gabriel showed up on the
4931 <a href=
"http://www.skolelinux.org/

</a

4932 mailing list. He quickly proved to be a valuable developer, and

</p

4937 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
4939 <p
>My name is Mike Gabriel, I am
38 years old and live near Kiel,
4940 Schleswig-Holstein, Germany. I live together with a wonderful partner
4941 (Angela Fuß) and two own children and two bonus children (contributed
4942 by Angela).
</p
>
4944 <p
>During the day I am part-time employed as a system administrator
4945 and part-time working as an IT consultant. The consultancy work
4946 touches free software topics wherever and whenever possible. During
4947 the nights I am a free software developer. In the gaps I also train in
4948 becoming an osteopath.
</p
>
4950 <p
>Starting in
2010 we (Andreas Buchholz, Angela Fuß, Mike Gabriel)
4951 have set up a free software project in the area of Kiel that aims at
4952 introducing free software into schools. The project
's name is
4953 "IT-Zukunft Schule
" (IT future for schools). The project links IT
4954 skills with communication skills.
</p
>
4956 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4957 project?
</strong
></p
>
4959 <p
>While preparing our own customised Linux distribution for
4960 "IT-Zukunft Schule
" we were repeatedly asked if we really wanted to
4961 reinvent the wheel. What schools really need is already available,
4962 people said. From this impulse we started evaluating other Linux
4963 distributions that target being used for school networks.
</p
>
4965 <p
>At the end we short-listed two approaches and compared them: a
4966 commercial Linux distribution developed by a company in Bremen,
4967 Germany, and Skolelinux / Debian Edu. Between
12/
2010 and
03/
2011 we
4968 went to several events and met people being responsible for marketing
4969 and development of either of the distributions. Skolelinux / Debian
4970 Edu was by far much more convincing compared to the other product that
4971 got short-listed beforehand--across the full spectrum. What was most
4972 attractive for me personally: the perspective of collaboration within
4973 the developmental branch of the Debian Edu project itself.
</p
>
4975 <p
>In parallel with this, we talked to many local and not-so-local
4976 people. People teaching at schools, headmasters, politicians, data
4977 protection experts, other IT professionals.
</p
>
4979 <p
>We came to two conclusions:
</p
>
4981 <p
>First, a technical conclusion: What schools need is available in
4982 bits and pieces here and there, and none of the solutions really fit
4983 by
100%. Any school we have seen has a very individual IT setup
4984 whereas most of each school
's requirements could mapped by a standard
4985 IT solution. The requirement to this IT solution is flexibility and
4986 customisability, so that individual adaptations here and there are
4987 possible. In terms of re-distributing and rolling out such a
4988 standardised IT system for schools (a system that is still to some
4989 degree customisable) there is still a lot of work to do here
4990 locally. Debian Edu / Skolelinux has been our choice as the starting
4993 <p
>Second, a holistic conclusion: What schools need does not exist at
4994 all (or we missed it so far). There are several technical solutions
4995 for handling IT at schools that tend to make a good impression. What
4996 has been missing completely here in Germany, though, is the enrolment
4997 of people into using IT and teaching with IT.
"IT-Zukunft Schule
"
4998 tries to provide an approach for this.
</p
>
5000 <p
>Only some schools have some sort of a media concept which explains,
5001 defines and gives guidance on how to use IT in class. Most schools in
5002 Northern Germany do not have an IT service provider, the school
's IT
5003 equipment is managed by one or (if the school is lucky) two (admin)
5004 teachers, most of the workload these admin teachers get done in there
5005 spare time.
</p
>
5007 <p
>We were surprised that only a very few admin teachers were
5008 networked with colleagues from other schools. Basically, every school
5009 here around has its individual approach of providing IT equipment to
5010 teachers and students and the exchange of ideas has been quasi
5011 non-existent until
2010/
2011.
</p
>
5013 <p
>Quite some (non-admin) teachers try to avoid using IT technology in
5014 class as a learning medium completely. Several reasons for this
5015 avoidance do exist.
</p
>
5017 <p
>We discovered that no-one has ever taken a closer look at this
5018 social part of IT management in schools, so far. On our quest journey
5019 for a technical IT solution for schools, we discussed this issue with
5020 several teachers, headmasters, politicians, other IT professionals and
5021 they all confirmed: a holistic approach of considering IT management
5022 at schools, an approach that includes the people in place, will be new
5023 and probably a gain for all.
</p
>
5025 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5026 Edu?
</strong
></p
>
5028 <p
>There is a list of advantages: international context, openness to
5029 any kind of contributions, do-ocracy policy, the closeness to Debian,
5030 the different installation scenarios possible (from stand-alone
5031 workstation to complex multi-server sites), the transparency within
5032 project communication, honest communication within the group of
5033 developers, etc.

5036 Edu?
</strong

5038 <p
>Every coin has two sides:
</p
>
5040 <p
>Technically:
<a href=
"http://bugs.debian.org/
311188">BTS issue
5041 #
311188</a
>, tricky upgradability of a Debian Edu main server, network
5042 client installations on top of a plain vanilla Debian installation
5043 should become possible sometime in the near future, one could think
5044 about splitting the very complex package debian-edu-config into
5045 several portions (to make it easier for new developers to
5046 contribute).
</p
>
5048 <p
>Another issue I see is that we (as Debian Edu developers) should
5049 find out more about the network of people who do the marketing for
5050 Debian Edu / Skolelinux. There is a very active group in Germany
5051 promoting Skolelinux on the bigger Linux Days within Germany. Are
5052 there other groups like that in other countries? How can we bring
5053 these marketing people together (marketing group A with group B and
5054 all of them with the group of Debian Edu developers)? During the last
5055 meeting of the German Skolelinux group, I got the impression of people
5056 there being rather disconnected from the development department of
5057 Debian Edu / Skolelinux.

><strong
>Which free software do you use daily?
</strong
></p
>
5061 <p
>For my daily business, I do not use commercial software at all.
</p
>
5063 <p
>For normal stuff I use Iceweasel/Firefox, Libreoffice.org. For
5064 serious text writing I prefer LaTeX. I use gimp, inkscape, scribus for
5065 more artistic tasks. I run virtual machines in KVM and Virtualbox.
</p

5067 <p
>I am one of the upstream developers of X2Go. In
2010 I started the
5068 development of a Python based X2Go Client, called PyHoca-GUI.
5069 PyHoca-GUI has brought forth a Python X2Go Client API that currently
5070 is being integrated in Ubuntu
's software center.
</p
>
5072 <p
>For communications I have my own Kolab server running using Horde
5073 as web-based groupware client. For IRC I love to use irssi, for Jabber
5074 I have several clients that I use, mostly pidgin, though. I am also
5075 the Debian maintainer of Coccinella, a Jabber-based interactive
5076 whiteboard.

12
5106 years (since
2000), I have been working for a comprehensive (and soon,
5107 also inclusive) school leading to all kind of general levels, such as
5108 O- or A-level (
"Abitur

3 years) and our daughter
5113 (
4 months).
</p
>
5115 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5116 project?
</strong
></p
>
5118 <p
>We had tried different Linux based school servers, when members of
5119 my local Linux User Group (LUG OWL) detected Skolelinux. I remember
5120 very well, being part of a party celebrating the Linux New Media Award
5121 (
"Best Newcomer Distribution
", also nominated: Ubuntu) that was given
5122 to Skolelinux at Linux World Exposition in Frankfurt,
2005 (IIRC). Few
5123 months later, I had the chance to join a developer meeting in Ulsrud
5124 (Oslo) and to hand out the award to Knut Yrvin and others. For more
5125 than
7 years, Skolelinux is part of our schools infrastructure, namely
5126 our main server (tjener), one LTSP (today without thin clients), and
5127 approximately
50 work stations. Most of these have the option to boot a
5128 locally installed Skolelinux image. As a consequence, I joined quite
5129 a few events dealing with free software or Linux, and met many Debian
5130 (Edu) developers. All of them seemed quite nice and competent to me,
5131 one more reason to stick to Skolelinux.

5133 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5134 Edu?
</strong
></p
>
5136 <p
>Debian driven, you are given all the advantages of a community
5137 project including well maintained updates. Once, you are familiar with
5138 the network layout, you can easily roll out an entire educational
5139 computer infrastructure, from just one installation media. As only
5140 free software (FOSS) is used, that supports even elderly hardware,
5141 up-sizing your IT equipment is only limited by space (i.e. available
5142 labs). Especially if you run a LTSP thin client server, your
5143 administration costs tend towards zero.
</p
>
5145 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
5146 Edu?
</strong
></p
>
5148 <p
>While Debian
's stability has loads of advantages for servers, this
5149 might be different in some cases for clients: Schools with unlimited
5150 budget might buy new hardware with components that are not yet
5151 supported by Debian stable, or wish to use more recent versions of
5152 office packages or desktop environments. These schools have the
5153 option to run Debian testing or other distributions - if they have the
5154 capacity to do so. Another issue is that Debian release cycles
5155 include a wide range of changes; therefor a high percentage of human
5156 power seems to be absorbed by just keeping the features of Skolelinux
5157 within the new setting of the version to come. During this process,
5158 the cogs of Debian Edu are getting more and more professional,
5159 i.e. harder to understand for novices.

5163 <p

</strong

5172 <li
>Support computer science as regular subject in schools to make
5173 people really
"own
" their hardware, to make them understand the
5174 difference between proprietary software products, and free software
5175 developing.
</li
>
5177 <li
>Make budget baskets corresponding: In Germany
's public schools
5178 there are more or less fixed budgets for IT equipment (including
5179 licenses), so schools won
't benefit from any savings here. This
5180 privilege is left to private schools which have consequently a large
5181 share among German Skolelinux schools.
</li
>
5183 <li
>Get free software in the seminars where would-be teachers are
5184 trained. In many cases, teachers
' software customs are respected by
5185 decision makers rather than the expertise of any IT experts.
</li
>
5187 <li
>Don
't limit ourself to free software run natively. Everybody uses
5188 free software or free licenses (for instance Wikipedia), and this
5189 general concept should get expanded to free educational content to be
5190 shared world wide (school books e.g.).
</li
>
5192 <li
>Make clear where ever you can that the market share of free (libre)
5193 office suites is much above
20 p.c. today, and that you pupils don
't
5194 need to know the
"ribbon menu
" in order to get employed.

>Spread free software, or even collections of portable free apps

5226 etter at ryggen sa takk før seg, studerte jeg nettverksadministrasjon
5227 ved Næringsakademiet i Bergen årene
2008-

</p
>
5233 <p
>Mitt mål er å bevisstgjøre musikklærene mulighetene med de frie
5234 programmene som finnes i Skolelinux, blant annet Rosegarden.
</p
>
5236 <p
>Har i mange år drevet med musikk og en av grunnen til at Rosegarden
5237 falt i smak for min del, var fordi denne fungere og ligner mest på
5238 Windows-programmet (cubase) jeg jobbet mye med da jeg i mine yngre
5239 dager var «Windows fanatiker». Ble introdusert til Linux av en kompis
5240 av meg for omtrent

5246 havnet jeg i

5248 Skolelinuxprosjektet.

>
5250 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
5252 <p
>Skolelinux er enkelt å holde i drift og masse flotte programmer som
5253 geogebra, ktouch og kgeografi følger med pakken. Man kan ta i bruk
5254 gamle PC-er igjen, slik at skoler med dårlig råd får opp en brukbar
5255 PC-park. PC-er som er ca
6-
9 år gamle fungere tilfredstillende, bare
5256 de har
512 MB RAM eller mer.
</p
>
5258 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
5260 <p
>Ulempene er at noen av de pedagogiske programmene som lærene ønsker
5261 å bruke fungere dårlig med Linux. Mye pga. av at disse programmene
5262 blir ikke laget til Linuxbaserte operativsystemer.
</p
>
5264 <p
>Video- og bilde-redigering har dessverre en del mangler, mange av
5265 programmene har en tendens til og krasje. Det gjelder blant annet
5266 <a href=
"http://www.kdenlive.org/
">kdenlive
</a
> og
5267 <a href=
"http://www.openshotvideo.com/
">openshot
</a
>, for å nevne
5268 noen. De er ikke stabile nok. Når elevene kommer med filmsnutter de
5269 ønsker og jobbe med, så godtar ikke programmene filene, og når elevene
5270 jobber med redigering bare krasjer programmene uten forvarsel. Det er
5271 for vanskelig å få noe som bare fungerer ut av boksen her. Når en elev
5272 plugger inn et videokamera eller fotoapparat så er det alltid noe som
5273 ikke vil fungere. Programmene godtar ikke format, godtar ikke
5274 kameraet, osv., osv. Det er dessverre med på og dra ned en positiv
5275 opplevelse av bruk av fri programvare.
</p
>
5277 <p
>Man må ofte bruke flere en et video redigerings program før og få
5278 fullført en ønsket oppgave.
</p
>
5280 <p
>Eksempel:
</p
>
5282 <p
>Hvis det ene programmet ikke vil ta i mot videofilen klarer et
5283 annet det, men det programmet som klarer det kan ikke gjøre de samme
5284 oppgavene som det programmet som ikke ville ta i mot filen,
5285 Tilsvarende er det med foto, man må bruke flere programmer for å få
5286 et ferdig resultat. Til dags dato har jeg enda ikke funnet et video-
5287 og fotoprogram som kan tilfredstillende fullføre en oppgave.
</p
>
5289 <p
>Så man kan klare og fullføre en oppgave, men i verste fall må man
5290 innom
3-
4 programmer for å få det til. Så jeg har enda ikke til dags
5291 dato sett at et program fungere
100% til alt.

5297 Lydsystemet kan også være et mareritt. Konkret snakker jeg om når du
5298 bruker for eksempel et smartboard, så følger det med USB-lydkort på
5299 disse. Problemet ligger her i at systemet ikke vil velge rett
5300 lydkort, så man må inn med padevchooser for å sette opp PulseAudio
5301 til og velge at USB-lydkortet skal brukes. Det blir for tungvindt for
5302 lærene, de ønsker at ting skal fungere med en gang. (min løsning på
5303 det problemet ble at jeg måtte deaktivere lydkortet som fantes på
5304 maskinen) men da må man bestandig slå på smartboard-tavla.

>It has been a few busy weeks for me, but I am finally back to
5327 publish another interview with the people behind
5328 <a href=
"http://www.skolelinux.org/
">Debian Edu and Skolelinux
</a
>.
5329 This time it is one of our German developers, who have helped out over the
5330 years to make sure both a lot of major but also a lot of the minor
5331 details get right before release.
5333 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
5335 <p
>My name is Jürgen Leibner, I
'm
49 years old and living in
5336 Bielefeld, a town in northern Germany. I worked nearly
20 years as
5337 certified engineer in the department for plant design and layout of an
5338 international company for machinery and equipment. Since
2011 I
'm a
5339 certified technical writer (tekom e.V.) and doing technical
5340 documentations for a steam turbine manufacturer. From April this year
5341 I will manage the department of technical documentation at a
5342 manufacturer of automation and assembly line engineering.
</p
>
5344 <p
>My first contact with linux was around
1993. Since that time I used
5345 it at work and at home repeatedly but not exclusively as I do now at
5346 home since
2006.
</p
>
5348 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5349 project?
</strong
></p
>
5351 <p
>Once a day in the early year of
2001 when I wanted to fetch my
5352 daughter from primary school, there was a teacher sitting in the
5353 middle of
20 old computers trying to boot them and he failed. I helped
5354 him to get them booting. That was seen by the school director and she
5355 asked me if I would like to manage that the school gets all that old
5356 computers in use. I answered:
"Yes
".
</p
>
5358 <p
>Some weeks later every of the
10 classrooms had one computer
5359 running Windows98. I began to collect old computers and equipment as
5360 gifts and installed the first computer room with a peer-to-peer
5361 network. I did my work at school without being payed in my spare time
5362 and with a lot of fun. About one year later the school was connected
5363 to Internet and a local area network was installed in the school
5364 building. That was the time to have a server and I knew it must be a
5365 Linux server to be able to fulfil all the wishes of the teachers and
5366 being able to do this in a transparent and economic way, without extra
5367 costs for things like licence and software. So I searched for a
5368 school server system running under Linux and I found a couple of
5369 people nearby who founded
'skolelinux.de
'. It was the Skolelinux
5370 prerelease
32 I first tried out for being used at the school. I
5371 managed the IT of that school until the municipal authority took over
5372 the IT management and centralised the services for all schools in
5373 Bielefeld in December of
2006.

>What do you see as the advantages of Skolelinux/Debian
5376 Edu?
</strong

5378 <p
>When I
'm looking back to the beginning, there were other advantages
5379 for me as today.
</p
>
5381 <p
>In the past there were advantages like:
</p
>
5385 <li
>I don
't need to buy it so it generates no costs to the school as
5386 they had little money to spent for computers and software.
</li
>
5388 <li
>It has a licence which grands all rights to use it without
5391 <li
>It was more able to fit all requirements of a server system for
5392 schools than a Microsoft server system, even if there are only Windows
5393 clients because of it
's preconfigured overall concept of being a
5394 infrastructure solution and community for schools, not only a
5397 <li
>I was able to configure the server to the needs of the
5400 </ul
></p
>
5402 <p
>Today some of the advantages has been lost, changed or new ones
5403 came up in this way:
</p
>
5407 <li
>Most schools here do have money to buy hardware and software
5410 <li
>They are today mostly managed from central IT departments which
5411 have own concepts which often do not fit to Debian Edu concepts
5412 because they are to close to Microsoft ideology.
</li
>
5414 <li
>With the Squeeze version of Debian Edu which now uses GOsa² for
5415 management I feel more able to manage the daily tasks than with the
5416 interfaces used in the past.
</li
>
5418 <li
>It is more modular than in the past and fits even better to the
5419 different needs.
</li
>
5421 <li
>The documentation is usable and gets better every day.
</li
>
5423 <li
>More people than ever before are using Debian Edu all over the
5424 world and so the community, which is an very important part I think,
5425 is sharing knowledge and minds.
</li
>
5427 <li
>Most, maybe all, of the technical requirements for schools are
5428 solved today by Debian Edu.

5432 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
5433 Edu?
</strong

>
5437 <li
>There are too few IT companies able to integrate Debian Edu into
5438 their product portfolio for serving schools with concepts or even
5439 whole municipality areas.
</li

5441 <li
>Debian Edu has beside other free and open software projects not
5442 enough lobbyists which promote free and open software to
5443 politicians.

5449 <p
><strong
>Which free software do you use daily?
</strong
></p
>
5451 <p
>I use Debian stable on my home server and on my little desktop
5452 computer. On my laptop I use Debian testing/sid. The applications I
5453 use on my laptop and my desktop are Open/Libre-office, Iceweasel,
5454 KMail, DigiKam, Amarok, Dolphin, okular and all the other programs I
5455 need from the KDE environment. On console I use newsbeuter, mutt,
5456 screen, irssi and all the other famous and useful tools.
</p
>
5458 <p
>My home server provides mail services with exim, dovecot, roundcube
5459 and mutt over ssh on the console, file services with samba, NFS,
5460 rsync, web services with apache, moinmoin-wiki, multimedia services
5461 with gallery2 and mediatomb and database services with MySQL for me
5462 and the whole family. I probably forgot something.

>Da jeg googlet etter noe annet kom jeg tilfeldigvis over
5479 <a href=
"http://www.duo.uio.no/sok/work.html?WORKID=
58309">en
5480 hovedfagsoppgave
</a
> ved Universitetet i Oslo som diskuterer verdien
5481 av GPLs fire friheter for brukerne av IT-systemer. Jeg ble fascinert
5482 over det som presenteres der. Her er sammendraget:
</p
>
5484 <p
><blockquote
>
5486 <p
>Motivasjonen til å skrive denne oppgaven er en personlig undring
5487 over hvorfor det primært, og ofte eksklusivt, fokuseres på det
5488 økonomiske aspektet ved utredninger om fri programvare er et godt valg
5489 for det offentlige. Fri og produsenteid programvare bygger på
5490 fundamentalt forskjellige ideologier som kan ha implikasjoner utover
5491 økonomiske kostnader. Kunnskapskulturen som er med på å definere fri
5492 programvare er basert på åpenhet, og er en verdi i seg selv.
</p
>
5494 <p
>Oppgavens tema er programvarelisensen GPL og frihet. GPL-lisensiert
5495 programvare gir visse friheter i forhold til produsenteid
5496 programvare. Mitt spørsmål er om, og eventuelt i hvilken utstrekning,
5497 disse frihetene blir benyttet av ulike brukere og hvordan de
5498 manifesterer seg for disse brukerne. Sentrale spørsmål i oppgaven
5502 <li
>Hvordan fordeles handlekraft gjennom lisensieringen av programvaren?
</li
>
5503 <li
>Hvilke konsekvenser har programvarelisensen for de ulike brukere?
</li
>
5506 <p
>Fri programvare gir blant annet brukeren mulighet til å studere og
5507 modifisere kildekoden. Denne formen for frihet erverves gjennom
5508 kunnskap og krever at brukeren også er en ekspert. Hva skjer med
5509 frihetene til GPL når sluttbrukeren er en annen? Dette diskuteres i
5510 dialog med informantene.
</p
>
5512 <p
>Jeg har i denne oppgaven samlet inn intervjudata fra IKT-ansvarlige
5513 ved grunnskolene i Nittedal kommune, driftsansvarlig og IKT-veilederen
5514 for skolene i kommunen, samt IKT-koordinator for utdanning i Akershus
5515 fylkeskommune og bokmåloversettere av OpenOffice.org. Den empiriske
5516 delen av oppgaven er delt inn i to seksjoner; den første omhandler
5517 operativsystemet Skolelinux, den andre kontorprogrampakken
5518 OpenOffice.org.
</p
>
5520 <p
>Som vi vil se gir GPL lokal frihet og kontroll gjennom omfordeling
5521 av makt fra produsent til bruker. Brukerens makt analyseres gjennom
5522 begrepene brukermedvirkning og handlingsfrihet. Det blir også lagt
5523 vekt på strukturelle forhold rundt bruken av teknologi, og spesielt de
5524 økonomiske begrepene nettverkseksternaliteter, innlåsing og
5525 stiavhengighet. Dette er begreper av spesiell nytte når objektet som
5526 omsettes eller distribueres er et kommunikasjonsprodukt, fordi verdien
5527 til et slikt gode for en potensiell bruker avhenger av antall
5528 eksisterende brukere av godet. I tilknytning til denne problematikken
5529 inneholder oppgaven også en diskusjon rundt åpne standarder og
5532 <p
>Oppgaven konkluderer med at de «fire frihetene» som GPL-lisensen er
5533 laget for å beskytte er av avgjørende betydning for bruken av
5534 OpenOffice.org og Skolelinux, i Akershus fylkeskommune såvel som i
5535 skolene i Nittedal. Distribusjonen av handlekraft er ikke helt
5536 symmetrisk. Det er først og fremst de profesjonelle utviklerne i
5537 Skolelinux som direkte kan nyttiggjøre seg friheten til å endre kode,
5538 mens en sluttbruker som Nittedal kommune nyttiggjør seg den økonomiske
5539 friheten til å kunne distribuere programmene. Det er imidlertid også
5540 slik at ingen aktør klarer seg uten alle disse «frihetene».

<a href=

">Debian Edu and
5557 Skolelinux
</a
> there are a lot of people doing the hard work of
5558 setting together all the pieces. This time I present to you Andreas
5559 Mundt, who have been part of the technical development team several
5560 years. He was also a key contributor in getting GOsa and Kerberos set
5561 up in the recently released
5562 <a href=

5567 <p
>My name is Andreas Mundt, I grew up in south Germany. After
5568 studying Physics I spent several years at university doing research in
5569 Quantum Optics. After that I worked some years in an optics company.
5570 Finally I decided to turn over a new leaf in my life and started
5571 teaching
10 to
19 years old kids at school. I teach math, physics,
5572 information technology and science/technology.
</p
>
5574 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5575 project?
</strong
></p
>
5577 <p
>Already before I switched to teaching, I followed the Debian Edu
5578 project because of my interest in education and Debian. Within the
5579 qualification/training period for the teaching, I started
5580 contributing.
</p
>
5582 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5583 Edu?
</strong
></p
>
5585 <p
>The advantages of Debian Edu are the well known name, the
5586 out-of-the-box philosophy and of course the great free software of the
5587 Debian Project!
</p
>
5589 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
5590 Edu?
</strong
></p
>
5592 <p
>As every coin has two sides, the out-of-the-box philosophy has its
5593 downside, too. In my opinion, it is hard to modify and tweak the
5594 setup, if you need or want that. Further more, it is not easily
5595 possible to upgrade the system to a new release. It takes much too
5596 long after a Debian release to prepare the -Edu release, perhaps
5597 because the number of developers working on the core of the code is
5598 rather small and often busy elsewhere.
</p
>
5600 <p
>The
<a href=

>
5601 project might fill the use case of a more flexible system.
</p
>
5603 <p
><strong
>Which free software do you use daily?
</strong
></p
>
5605 <p
>I am only using non-free software if I am forced to and run Debian
5606 on all my machines. For documents I prefer LaTeX and PGF/TikZ, then
5607 mutt and iceweasel for email respectively web browsing. At school I
5608 have Arduino and Fritzing in use for a micro controller project.
</p
>
5610 <p
><strong
>Which strategy do you believe is the right one to use to
5611 get schools to use free software?
</strong
></p
>
5613 <p
>One of the major problems is the vendor lock-in from top to bottom:
5614 Especially in combination with ignorant government employees and
5615 politicians, this works out great for the
"market-leader
". The school
5616 administration here in Baden-Wuerttemberg is occupied by that vendor.
5617 Documents have to be prepared in non-free, proprietary formats. Even
5618 free browsers do not work for the school administration. Publishers
5619 of school books provide software only for proprietary platforms.
</p
>
5621 <p
>To change this, political work is very important. Parts of the
5622 political spectrum have become aware of the problem in the last years.
5623 However it takes quite some time and courageous politicians to
'free
'
5624 the system. There is currently some discussion about
"Open Data
" and
5625 "Free/Open Standards
". I am not sure if all the involved parties have
5626 a clue about the potential of these ideas, and probably only a
5627 fraction takes them seriously. However it might slowly make free
5628 software and the philosophy behind it more known and popular.

5696 up a
<a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>
5697 Lenny installation using LTSP diskless workstations, and in the
5698 process I discovered something very surprising. The reason the KDE
5699 menu was responding slow when using it for the first time, was mostly
5700 due to the way KDE find application icons. I discovered that showing
5701 the Multimedia menu would cause more than
20 000 IP packages to be
5702 passed between the LTSP client and the NFS server. Most of these were
5704 NFS LOOKUP calls, resulting in a NFS3ERR_NOENT response. Because the
5705 ping times between the client and the server were in the range
2-
20
5706 ms, the menus would be very slow. Looking at the strace of kicker in
5707 Lenny (or plasma-desktop i Squeeze - same problem there), I see that
5708 the source of these NFS calls are access(
2) system calls for
5709 non-existing files. KDE can do hundreds of access(
2) calls to find
5710 one icon file. In my example, just finding the mplayer icon required
5711 around
230 access(
2) calls.
</p
>
5713 <p
>The KDE code seem to search for icons using a list of icon
5714 directories, and the list of possible directories is large. In
5715 (almost) each directory, it look for files ending in .png, .svgz, .svg
5716 and .xpm. The result is a very slow KDE menu when /usr/ is NFS
5717 mounted. Showing a single sub menu may result in thousands of NFS
5718 requests. I am not the first one to discover this. I found a
5719 <a href=
"https://bugs.kde.org/show_bug.cgi?id=
211416">KDE bug report
5720 from
2009</a
> about this problem, and it is still unsolved.
</p
>
5722 <p
>My solution to speed up the KDE menu was to create a package
5723 kde-icon-cache that upon installation will look at all .desktop files
5724 used to generate the KDE menu, find their icons, search the icon paths
5725 for the file that KDE will end up finding at run time, and copying the
5726 icon file to /var/lib/kde-icon-cache/. Finally, I add symlinks to
5727 these icon files in one of the first directories where KDE will look
5728 for them. This cut down the number of file accesses required to find
5729 one icon from several hundred to less than
5, and make the KDE menu
5730 almost instantaneous. I
'm not quite sure where to make the package
5731 publicly available, so for now it is only available on request.
</p
>
5733 <p
>The bug report mention that this do not only affect the KDE menu
5734 and icon handling, but also the login process. Not quite sure how to
5735 speed up that part without replacing NFS with for example NBD, and
5736 that is not really an option at the moment.

5770 user community, and this time I managed to get hold of Wolfgang
5771 Schweer, a valuable contributor to the project from Germany.
5773 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
5775 <p
>I
've studied Mathematics at the university
'Ruhr-Universität
' in
5776 Bochum, Germany. Since
1981 I
'm working as a teacher at the school
5777 "<a href=
"http://www.westfalenkolleg-dortmund.de/
">Westfalen-Kolleg
5778 Dortmund
</a
>", a second chance school. Here, young adults is given
5779 the opportunity to get further education in order to do the school
5780 examination
'Abitur
', which will allow to study at a university. This
5781 second chance is of value for those who want a better job perspective
5782 or failed to get a higher school examination being teens.
</p
>
5784 <p
>Besides teaching I was involved in developing online courses for a
5785 blended learning project called
'abitur-online.nrw
' and in some other
5786 information technology related projects. For about ten years I
've been
5787 teacher and coordinator for the
'abitur-online
' project at my
5788 school. Being now in my early sixties, I
've decided to leave school at
5789 the end of April this year.
</p
>
5791 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5792 project?
</strong
></p
>
5794 <p
>The first information about Skolelinux must have come to my
5795 attention years ago and somehow related to LTSP (Linux Terminal Server
5796 Project). At school, we had set up a network at the beginning of
1997
5797 using Suse Linux on the desktop, replacing a Novell network. Since
5798 2002, we used old machines from the city council of Dortmund as thin
5799 clients (LTSP, later Ubuntu/Lessdisks) cause new hardware was out of
5800 reach. At home I
'm using Debian since years and - subscribed to the
5801 Debian news letter - heard from time to time about Skolelinux. About
5802 two years ago I proposed to replace the (somehow undocumented and only
5803 known to me) system at school by a well known Debian based system:
5804 Skolelinux.
</p
>
5806 <p
>Students and teachers appreciated the new system because of a
5807 better look and feel and an enhanced access to local media on thin
5808 clients. The possibility to alter and/or reset passwords using a GUI
5809 was welcomed, too. Being able to do administrative tasks using a GUI
5810 and to easily set up workstations using PXE was of very high value for
5811 the admin teachers.
</p
>
5813 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5814 Edu?
</strong
></p
>
5816 <p
>It
's open source, easy to set up, stable and flexible due to it
's
5817 Debian base. It integrates LTSP out-of-the-box. And it is documented!
5818 So it was a perfect choice.
</p
>
5820 <p
>Being open source, there are no license problems and so it
's
5821 possible to point teachers and students to programs like
5822 OpenOffice.org, ViewYourMind (mind mapping) and The Gimp. It
's of
5823 high value to be able to adapt parts of the system to special needs of
5824 a school and to choose where to get support for this.
</p
>
5826 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
5827 Edu?
</strong
></p
>
5829 <p
>Nothing yet.
</p
>
5831 <p
><strong
>Which free software do you use daily?
</strong
></p
>
5833 <p
>At home (Debian Sid with Gnome Desktop): Iceweasel, LibreOffice,
5834 Mutt, Gedit, Document Viewer, Midnight Commander, flpsed (PDF
5835 Annotator). At school (Skolelinux Lenny): Iceweasel, Gedit,
5836 LibreOffice.
</p
>
5838 <p
><strong
>Which strategy do you believe is the right one to use to
5839 get schools to use free software?
</strong
></p
>
5841 <p
>Some time ago I thought it was enough to tell people about it. But
5842 that doesn
't seem to work quite well. Now I concentrate on those more
5843 interested and hope to get multiplicators that way.

5861 <p
>Det er store forskjeller på skolenes digitale tilstand, viser
5862 undersøkelsen Monitor
2011 som er laget på oppdrag fra
5863 Kunnskapsdepartementet. Dette har ført til debatt om PC-tilgangen i
5864 skolen, og om de med Linux i skolen gjør det bedre bedre eller
5865 dårligere enn snittet i landet.
</p
>
5867 <p
>Nå har vi tallene. Skoler med Linux har
36% større PC-tetthet en
5868 landsgjennomsnittet. På spørsmål hvorfor skoler med Linux har større
5869 PC-tetthet, observerer Paul Reidar Løsnesløkken som er IKT-konsulent i
5870 Nord-Odal:
</p
>
5872 <p
><blockquote
>"Vi erfarer at klienter med Skolelinux har god funksjon
5873 til de er
8 til
10 år gamle. Dette er omtrent dobbelt så lenge som
5874 andre løsninger, og skolene får mer datautstyr for
5875 pengene.
"</blockquote
></p
>
5877 <p
>Undersøkelsen baserer seg på
56 skoler som har gjort det offentlig
5878 at de kjører Skolelinux eller annen Linux-utgave. De kan også ha PC-er
5879 med Windows i skolenettet. Når en sammenligner PC-tetthetene på
5880 skolene i kommunene Flora, Harstad, Kongsvinger, Narvik, Nittedal,
5881 Nord-Odal og Randaberg, er det i snitt
2,
28 elev pr. PC på skolene med
5882 Linux. På landsbasis er det
3.11 elev per PC i grunnskolen, i følge
5883 side
95 i Monitor-rapporten for
2011. Målingen viser dermed
36% større
5884 PC-tetthet i skoler med Linux.

5888 <p
>Skolelinux har til hensikt å gi alle barn full tilgang til
5889 skoleaktuelle dataprogram på sitt eget morsmål. Derfor følger det med
5890 godt over
100 skoleaktuelle programmene laget for læring. De fleste
5891 programmene er oversatt til over
50 språk. Elevene skal også kunne
5892 studere alle sider av dataprogrammene. Derfor følger også kildekode
5893 med. Elever med interesse kan lære av eksperter som har laget
5894 systemet. Dette med enkelt programmering i læreprogram som KTurtle,
5895 til profesjonelle verktøy som Qt Creator eller Java.
</p
>
5897 <p
>Skolelinux er laget for sentralisert drift, der alt teknisk
5898 administrasjon av alle skolene kan gjøres sentralt fra kommunehuset
5899 eller sentralt i en region. F.eks. drifter to-tre personer
70.000
5900 skoledatamaskiner på
200 skoler i delstaten Extremadura i
5901 Spania. Etter velykket bruk av Debian Edu i skolen, legger delstaten
5902 over til Debian på
40.000 datamaskiner i administrasjonen. Det er idag
5903 mange selskap som tilbyr profesjonell støtte til innføring og drift i
5904 Norge og verden.

5941 <description><p
>I serien med intervjuer av folk i
5942 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet, får vi
5943 denne gangen høre fra en IKT-ansvarlig som har brukt Skolelinux i
5944 mange år, og vært storfornøyd med erfaringene så langt.
</p
>
5946 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
5948 <p
>Mitt navn er Roy-Arne Myhre og jeg er
42 år. Jeg er ansatt hos
5949 <a href=
"http://www.sandskole.no/
">Sand skole
</a
> (Balsfjord kommune)
5950 og har stort sett vært det siden
1990. Jeg er IKT ansvarlig ved
5951 skolen i
40% stilling –
10% undervisning – musikk.
</p
>
5953 <p
>Ved skolen er det ca
100 elever og ca
18 lærere +
4 assistenter i
5954 hele og delte stillinger. Alle lærerne har bærbar PC (dessverre med
5955 Win Vista) – assistenter har tilgang til egne. Vi benytter Fronter i
5956 det daglige arbeidet. Vi har ca
90 elevmaskiner som fungerer til
5957 daglig opp mot Linux server (XFCE) som driftes av
5958 <a href=
"http://www.bzz.no/
">BzzWare AS
</a
> via nett. Maskinparken
5959 består kun av brukt utstyr for elevene – og noe av dette begynner å
5960 bli vel gammelt selv som halvtykke klienter.
</p
>
5962 <p
><strong
>Hvordan kom du i kontakt med
5963 Skolelinux-prosjektet?
</strong
></p
>
5965 <p
>Vi kom første gang i kontakt med Skolelinux rundt
1997. Den gang
5966 var det oppstart-disketter i hver maskin, ikke mulighet for lyd og
5967 video, gamle nettverkskort og mye plundring. Vi hadde en ihuga
5968 forelder med som pådriver, forsker og inspirator for hele opplegget.
5969 Selv ante jeg knapt at Skolelinux fantes, men han var av den
5970 utforskende typen, og fikk både meg og skolelederen i trua på at dette
5971 var ting som kunne fungere. Etter dette har det gått gradvis
5972 framover; flere maskiner er hentet inn gjennom bl.a
5973 <a href=
"http://www.greentech.no/
">Greentech
</a
> og utrangert utstyr
5974 fra høgskole / Avinor og private givere. Når maskinene ble for trege
5975 for nye Windows-versjoner, sto vi klare til å putte dem i nettverket
5976 vårt. Dette betyr at vi i dag har
1:
1 dekning av maskiner på
5977 ungdomstrinnet og bedre enn
1:
2 på barnetrinnet. Dette er vi veldig
5978 fornøyd med, og vi kan ikke se for oss hverdagen som ville vært
5979 alternativet ved bruk av Windows med sine lisenser pr. Bruker/maskin.
5980 Da ville vi nok vært tilbake til
1-
2 maskiner pr klasserom med de
5981 negative konsekvenser det ville hatt for undervisningsformene våre. Vi
5982 kan ha en hel klasse i prosjektjobbing eller individuell jobbing
5983 samtidig – vi kan avholde tentamen og eksamen uten
5984 logistikkproblemer.
</p
>
5986 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
5988 Hvor skal jeg begynne... Stabiliteten er et nøkkelord - det bare
5989 virker. Har du først fått en server med Skolelinux opp og gå, så må
5990 det en maskinarefeil eller sabotasje til for å stoppe den. Det at man
5991 kan bruke eldre maskiner som normalt sett ville gått på dynga, er også
5992 glimrende - billig for skoler med dårlig økonomi og bra for miljøet
5993 siden vi gjenbruker utstyr i stedet for å skaffe nytt. Vi ville aldri
5994 hatt mulighet til å operere med det maskinantallet vi har pr i dag
5995 hvis det ikke var for Skolelinux - så tilgjengelighet er et annet
5996 nøkkelord. Et tredje moment er sikkerhet og brukertilgang. Alle
5997 brukerer opererer med egne brukernavn og passord, samt egne
5998 brukerområder som kan tilpasses for både enbrukertilgang og for
5999 samarbeid med andre.
6001 Elever har godt av å se at det finnes andre alternativer enn de som
6002 storindustrien selger på lisensbasis - på den måten trenes de opp til
6003 å se flere muligheter og å foreta valg ut fra flere opsjoner.
6005 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6007 <p
>Ulempene med Skolelinux er nok utbredelsen og mangelen på kjennskap
6008 til dette i skolenorge. De som skal ta økonomiske avgjørelser rynker
6009 på nesen og vil gå for det kjente og «sikre» selv om det koster mye
6010 mer. Man får rett og slett litt hetta av å ikke kunne noe – og unngår
6011 dette for enhver pris.
</p
>
6013 <p
>I tillegg er mye av linux-systemet administrert av tekstkommandoer
6014 og er lite intuitiv/visuell for oss som ikke er «inne i»
6015 kildekodene». Så problemet er nok mye godt at de som
6016 utarbeider/drifter Skolelinux ikke helt klarer å sette seg ned på
6017 skoleadministratorens nivå når det gjelder problemer og
6018 utfordringer. Men dette er nok en utfordring alle administratorer
6019 sliter med uansett OS.
</p
>
6021 <p
>Derfor har vi valgt å støtte oss til BzzWare AS for assistanse i
6022 drifta slik at jeg har kunnet konsentrere meg mer om kabling, skifting
6023 av komponenter, veiledning av lærere og elever, vedlikehold av
6024 skrivere og annen daglig drift.
</p
>
6026 <p
>Elevene mestrer Skolelinux helt fint. Så lenge Internett
6027 (Iceweasel) og Libreoffice (Openoffice) fungerer er
90% av
6028 skolehverdagen velfungerende. I tillegg brukes jo en del av den
6029 pedagogiske programpakken bla. i forhold til matematikk og geografi,
6030 men det er såpass mye bra på nett om dagen, så disse programmene er
6031 mer som krydder å regne.
</p
>
6033 <p
>Jeg skulle ønske neste versjon av Skolelinux kunne komme litt
6034 mindre stappet med programmer, for halvparten blir aldri brukt, eller
6035 fungerer ikke uansett. Hva med et pedagogisk panel av lærere/IKT
6036 ansvarlige som kunne sagt: disse programmene skal være standard, så
6037 får resten være slike man kan legge til ved behov – det kan lett bli
6038 en jungel å bevege seg i.
</p
>
6040 <p
>Jeg ønsker meg også en mer grafisk versjon av
6041 <a href=
"http://bzz.no/lwat/trac/trac.cgi
">Lwat
</a
> hvor man kan krysse
6042 ut de som f.eks ikke skal ha internett-tilgang en dag pga
6043 eksamen/tentamen, samt en noe enklere brannmurløsning hvor man kan
6044 stenge for en del (få) sider på en enkel måte. Jeg liker godt
6045 Skolelinux sin ideologi om at filteret skal trenes i hodet på eleven –
6046 men av og til skulle jeg ønske at f.eks Facebook og Youtube kunne vært
6047 koblet vekk en periode for å få bedre utnyttelse av tid og
6048 ressurser. Disse to nettstedene er nok mye av årsaken til at mange
6049 lærere holder igjen databruken noe mer enn man kunne ønske.
</p
>
6051 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
6053 Jeg benytter nesten bare fri programvare til daglig. LibreOffice,
6054 Iceweasel (Firefox), Thunderbird til e-post og Gimp til
6055 bildebehandling. Vi har PHP-Nuke-oppsatt hjemmeside. Det eneste som
6056 jeg ikke har fått helt til enda er videoredigering - her må man vel
6057 innrømme at Mac er hakket over, men da er vi igjen over på å se hva
6058 som egner seg best, og ta valg ut fra det. Folk flest lever i
6059 villfarelsen om at regneark HETER Excel og tekstbehandling HETER
6060 Word. Dette er en misforståelse som jeg bruker mye energi på å
6061 diskutere og
"åpne sinn
" på Microsoft-slaver. Dessverre er det mange
6062 IKT-ansvarlige som også har låst seg på at det eneste saliggjørende er
6063 Bill G sine produkter.
6065 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
6066 skoler til å ta i bruk fri programvare?
</strong
></p
>
6068 <p
>For å komme lenger i utbredelsen av Skolelinux tror jeg det må mer
6069 fram i nasjonale medier, samt komme bedre fram hva økonomien i dette
6070 valget vil være – samt mulighetene. Fri programvare er en berikelse og
6071 gjør oss i stand til å utføre arbeidet i skolen uten å måtte legge
6072 igjen tusener på tusener i Bill Gates lomme.. Få ETT nettsted med
6073 forståelig veiledning av installasjon/oppgradering og ETT forum med
6074 konkrete feilrettinger og problemer, så tror jeg vi kunne kommet et
6075 par skritt framover. Ellers tror jeg bare at ildsjelene må fortsette å
6076 skinne – kanskje flere enn oss følger etter på veien.

>The same Debian Edu developer that did the last screen cast I
6088 published, Wolfgang Schweer, has created a new screen cast showing how
6089 to set up Kmail in Debian Edu Squeze to authenticate using Kerberos,
6090 allowing users to check their local email account without providing
6091 any password. The video is embedded here in quarter size,

>Den siste uka har det vært en del skriverier om hvor store
6111 forskjeller det er mellom skolene når det gjelder digital kompetanse.
6113 <a href=
"http://www.digi.no/
891660/bekymret-for-it-i-skolen
">oppslaget
6114 i Digi
</a
>. Diskusjonen fikk meg til å bli litt nysgjerrig på om
6115 Linux-skoler har større PC-tettet enn snittet i landet. Grunnlaget
6116 for diskusjonen har vært undersøkelsen
6117 <a href=
"https://iktsenteret.no/ressurser/monitor-
2011-skolens-digitale-tilstand
">Monitor
6118 2011</a
>, som bruker informasjon fra
6119 <a href=
"https://www.wis.no/gsi
">Grunnskolens Informasjonssystem
</a
>
6120 (GSI). GSI-data kan lastes ned fra web og jeg lastet ned en Excel-fil
6121 (intet åpen standard-valg tilgjengelig) med navn på alle skoler,
6122 hvilke kommune de befinner seg i og hvor mange elever pr. elev-PC de
6123 har rapportert inn. For å få en ide om svaret trenger jeg deretter å
6124 vite hvilke skoler i landet som bruker Linux, slik at jeg kan slå dem
6125 opp i GSI og finne ut hvor stor PC-tetthet de har.
</p
>
6127 <p
>Jeg vet om skoler i Balsfjord, Flora, Harstad, Kongsvinger, Narvik,
6128 Nittedal, Nord-Odal, Randaberg og Sunndal som bruker Skolelinux eller
6129 andre Linux-varianter. Jeg tror det er flere enn de
56 skolene jeg
6130 har klart å identifisere de siste dagene, men har ikke klart å få det
6131 bekreftet med offentlige kilder.
</p
>
6133 <p
>Monitor
2011-rapporteres side
95 forteller at det
"ifølge GSI
6134 (
20120-
2011) er det
3,
11 elever per datamaskin når vi tar med alle
6135 grunnskoler (
1.-
10.trinn)
". For de
56 Linux-skolene jeg har klart å
6136 koble mot informasjon i GSI er det
2,
28 elever per elevdatamaskin,
6137 hvilket betyr at det er
36% høyere PC-tetthet på Linux-skoler enn
6138 landsgjennomsnittet. Linux-skolen med høyest tettet blant de jeg har
6139 notert -skole er Flora ungdomsskule i Flora kommune med
0.82 elev
6140 pr. PC (
482 elever,
588 elevdatamaskiner).
</p
>
6142 <p
>Skolelinux gir datamaskiner lengre levetid, og en kan dermed få
6143 flere operative datamaskiner for samme budsjett, i tillegg til en
6144 rekke andre fordeler. Kan det være forklaringen på forskjellen?
</p
>
6146 <p
>Tallene må tas med en liten klype, da GSI ser ut til å ha endel
6147 feilføringer. Jeg synes i hvert fall en skole med
423 elever og
9
6148 elevmaskiner ser mistenkelig ut. Eller en skole med
346 elever,
0
6149 elevmaskiner, som er et annet ekstremt eksempel jeg fant.

6152 Trond Mæhlum for innspill om skoler med Linux.

>Who are you, and how do you spend your days?
</strong
></p
>
6169 <p
>I teach ICT part time at the Rudolf Steiner School in Kings
6170 Langley, near London, UK. Previously I worked as a technical
6171 author/trainer while my children attended the school, and I also
6172 contributed to the Schoolforge UK community with the aim of
6173 encouraging UK schools to adopt free/open source software. Five or six
6174 years ago we had about
50 schools interested in some way, but we
6175 weren
't able to convert many of them into sustainable
6176 installations.
</p
>
6178 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
6179 project?
</strong
></p
>
6181 <p
>Skolelinux had two representatives at an early Edubuntu meeting in
6182 London which I attended. However at that time our school network had
6183 just been installed using CentOS, LTSP
4 and GNOME. When LTSP
5 came
6184 along we switched to Edubuntu thin client servers so now we have a
6185 mixed environment which includes Windows PCs and student laptops, as
6186 well as their MacBooks and iPads. However, the proprietary systems
6187 have always been rather problematic, and we never built a GUI for the
6188 LDAP server, so when I discovered Skolelinux is configured for all
6189 these things we decided to try it.
</p
>
6191 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
6192 Edu?
</strong
></p
>
6194 <p
>By far the biggest advantage is the Debian Edu community. Apart
6195 from that I have always believed in the same
"sustainable computing
"
6196 goals that Skolelinux is built on: installing Linux on computers which
6197 would otherwise be thrown away, to provide a reliable, secure and
6198 low-cost IT environment for schools. From my own experience I know
6199 that a part-time person can teach and manage a network of about
25
6200 Linux computers, but it would take much more of my time if we had
6201 proprietary software everywhere.
</p
>
6203 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
6204 Edu?
</strong
></p
>
6206 <p
>As a newcomer I
'm just finding out who
's who in the community and
6207 how you
're organised, and what your procedures are for dealing with
6208 various things such as editing manual pages and so-on. The only
6209 English language mailing list seems to be for developers as well as
6210 users, so my inbox needs heavy pruning each day!
</p
>
6212 <p
><strong
>Which free software do you use daily?
</strong
></p
>
6214 <p
>Besides the software already mentioned at school we use Samba,
6215 OpenLDAP, CUPS, Nagios and Dansguardian for the network, and on the
6216 desktops we have LibreOffice, Firefox, GIMP and Inkscape. At home I
6217 use Ubuntu and an Android
4 eePad Transformer (but I
'm not sure if
6218 that counts...)
</p
>
6220 <p
><strong
>Which strategy do you believe is the right one to use to
6221 get schools to use free software?
</strong
></p
>
6223 <p
>That
's a tough question! For very many years UK schools installed
6224 and taught only proprietary software, so that at the highest levels
6225 the notion of
"computer
" means simply
"proprietary office
6226 applications
". However, schools today are experiencing budget
6227 constraints, and many are having to think hard about upgrading Windows
6228 XP. At the same time, we have students showing teachers how to use
6229 iPads, MacBooks and Android, so the choice of operating system is no
6230 longer quite so automatic. What is more, our government at last
6231 realised that we need people with programming skills, so they
're
6232 putting coding back in the curriculum! And it
's encouraging that the
6233 first
10,
000 Raspberry Pi units sold out in
2 hours.
</p
>
6235 <p
>I don
't really know what strategy is going to get UK schools to use
6236 free software, but building an active community of Skolelinux/Debian
6237 Edu users in this country has to be part of it.

>Documentation in Debian Edu is provided in several languages, and
6247 it is important to make it both easy to contribute and to keep the
6248 translated versions in sync. To do this we have come up with what we
6249 believe is a very efficient work flow.
</p
>
6253 <li
>The documentation is written in a
6254 <a href=
"http://moinmo.in
">moinmoin wiki
</a
> (see for example
6255 <a href=
"http://wiki.debian.org/DebianEdu/Documentation/Squeeze
">the
6256 Squeeze release manual
</a
>) with support for exporting the content as
6257 docbook XML.
</li
>
6259 <li
>This docbook document is given to po4a to extract a gettext style
6260 .pot file with the content, which in turn is used to create .po files
6261 with the translated text.
</li
>
6263 <li
>The .po files are given to translators, and they can always tell
6264 which part of the original wiki document is new or changed. They can
6265 use their normal translation tools like lokalize or poedit to write
6266 the translation. There is even a system in place to handle translated
6269 <li
>The translated .po files are combined with the original docbook
6270 XML document using po4a to create a translated docbook document.
</li
>
6272 <li
>The final step is to use all the generated docbook files and
6273 create PDF and HTML version of the original and translated documents.
</li
>
6277 <p
>This setup work very well, but have a few issues. The biggest
6278 issue is that
<a href=
"http://moinmo.in/DocBook
">the docbook support
6279 we use in moinmoin
</a
> is not actively maintained. The docbook
6280 support is also buggy, and our build system contain workarounds to
6281 make sure the generated docbook is usable despite these bugs.
</p
>
6283 <p
>If you want to have a look at our setup, it is all there in the

6340 <p

6341 har også en datter som går på en friskole, som også bruker Skolelinux.
6342 Som kjent har ikke friskoler de samme økonomiske rammebetingelsene som
6343 offentlige skoler, så for dem var det det absolutt beste alternativet.
6344 De anser også Skolelinux som et stabilt system, som bare går og går (i

6351 lydløse og raskere arbeidsstasjoner som er bedre i klasserommet.
6352 Lengre levetid på PC
'er. Store besparelser på maskinvare og drift. Og
6353 så klart fjerning av alle lisenskostnader. Personlig synes jeg også at
6354 mange av programmene er bedre enn alternativene. Men dette er ofte en
6355 smakssak og avhengig om man må ha det man er vant til fra før.

6360 kompatibilitet med arbeidsstasjoners/bærbare maskiner sine
6361 nettverksdrivere eller skjermkort. Men dette løser vi i skolene ved
6362 standardisering. Ellers er det få, om nesten ingen, av de kjente
6363 maskinvare / infrastruktur leverandørene til fylkes- / kommuner som
6364 tilbyr denne plattformen. Skal dette endre seg så må kommunene selv
6365 sette slike krav til leverandørene.

6377 <p
>Fortsette å presentere flere av de gode eksemplene hvor Debian Edu
6378 / Skolelinux brukes i kommuner og enkeltskoler. Vi må få bedre frem
6379 at det er mulig tilknytte både Windows og Mac klienter på denne
6380 plattformen (selv om det vil øke driftskostnadene). Dette gjøres
6381 mange steder. Spesielt er det mange lærere som ønsker å bruke
6382 Windows/Mac-bærbare, gjerne som sin private PC også. Det er også mulig
6383 for kommunen å integrere med Active Directory i stedet for OpenLDAP
6384 som kommer med ut av boksen (selv om også dette øker kostnadene).
6385 Dette vil muligens bidra til å fjerne noe motstand hos noen
6386 potensielle brukere / driftpersonell for å ta i bruk noe
6387 nytt. Fremveksten av mobile brukere og nettbrett går i vår favør.
6388 Brukerne blir kjent og vant til flere nye operativsystemer /
6389 brukergrensesnitt. Så utviklerfellesskapet bør jobbe videre med å
6390 integrere flere nye klienttyper, som ultra lav-kostklienter og
6391 nettbrett (blant annet fri programvare-alternativet

6433 work out of the box in Japan. I got him to answer a few questions,
6434 and am happy to share the response with you. :)

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

6439 <p
>My name is Nigel Barker, and I am British. I am married to Yumiko,
6440 and we have three lovely children, aged
15,
14 and
4(!) I am the IT
6441 Coordinator at Hiroshima International School, Japan. I am also a
6442 teacher, and in fact I spend most of my day teaching Mathematics,
6443 Science, IT, and Chemistry. I was originally a Chemistry teacher, but
6444 I have always had an interest in computers. Another teacher teaches
6445 primary school IT, but apart from that I am the only computer person,
6446 so that means I am the network manager, technician and webmaster,
6447 also, and I help people with their computer problems. I teach python
6448 to beginners in an after-school club. I am way too busy, so I really
6449 appreciate the simplicity of Skolelinux.

>How did you get in contact with the Skolelinux/Debian Edu
6452 project?
</strong
></p
>
6454 <p
>In around
2004 or
5 I discovered the ltsp project, and set up a
6455 server in the IT lab. I wanted some way to connect it to our central
6456 samba server, which I was also quite poor at configuring. I discovered
6457 Edubuntu when it came out, but it didn
't really improve my setup. I
6458 did various desperate searches for things like
"school Linux server
"
6459 and ended up in a document called
"Drift
" something or other. Reading
6460 there it became clear that Skolelinux was going to solve all my
6461 problems in one go. I was very excited, but apprehensive, because my
6462 previous attempts to install Debian had ended in failure (I used
6463 Mandrake for everything - ltsp, samba, apache, mail, ns...). I
6464 downloaded a beta version, had some problems, so subscribed to the
6465 Debian Edu list for help. I have remained subscribed ever since, and
6466 my school has run a Skolelinux network since Sarge.

>What do you see as the advantages of Skolelinux/Debian
6469 Edu?
</strong
></p
>
6471 <p
>For me the integrated setup. This is not just the server, or the
6472 workstation, or the ltsp. Its all of them, and its all configured
6473 ready to go. I read somewhere in the early documentation that it is
6474 designed to be setup and managed by the Maths or Science teacher, who
6475 doesn
't necessarily know much about computers, in a small Norwegian
6476 school. That describes me perfectly if you replace Norway with
6479 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
6480 Edu?
</strong
></p

6482 <p
>The desktop is fairly plain. If you compare it with Edubuntu, who
6483 have fun themes for children, or with distributions such as Mint, who
6484 make the desktop beautiful. They create a good impression on people
6485 who don
't need to understand how to use any of it, but who might be
6486 important to the school. School administrators or directors, for
6487 instance, or parents. Even kids. Debian itself usually has ugly
6488 default theme settings. It was my dream a few years back that some
6489 kind of integration would allow Edubuntu to do the desktop stuff and
6490 Debian Edu the servers, but now I realise how impossible that is. A
6491 second disadvantage is that if something goes wrong, or you need to
6492 customise something, then suddenly the level of expertise required
6493 multiplies. For example, backup wasn
't working properly in Lenny. It
6494 took me ages to learn how to set up my own server to do rsync backups.
6495 I am afraid of anything to do with ldap, but perhaps Gosa will
6498 <p
><strong
>Which free software do you use daily?
</strong
></p
>
6500 <p
>Nowadays I only use Debian on my personal computers. I have one for
6501 studio work (I play guitar and write songs), running AV Linux
6502 (customised Debian) a netbook running Squeeze, and a bigger laptop
6503 still running Skolelinux Lenny workstation. I have a Tjener in my
6504 house, that
's very useful for the family photos and music. At school
6505 the students only use Skolelinux. (Some teachers and the office still
6506 have windows). So that means we only use free software all day every
6507 day. Open office, The GIMP, Firefox/Iceweasel, VLC and Audacity are
6508 installed on every computer in school, irrespective of OS. We also
6509 have Koha on Debian for the library, and Apache, Moodle, b2evolution
6510 and Etomite on Debian for the www. The firewall is Untangle.
</p

6512 <p
><strong
>Which strategy do you believe is the right one to use to
6513 get schools to use free software?
</strong
></p
>
6515 <p
>Current trends are in our favour. Open source is big in industry,
6516 and ordinary people have heard of it. The spread of Android and the
6517 popularity of Apple have helped to weaken the impression that you have
6518 to have Microsoft on everything. People complain to me much less about
6519 file formats and Word than they did
5 years ago. The Edu aspect is
6520 also a selling point. This is all customised for schools. Where is the
6521 Windows-edu, or the Mac-edu? But of course the main attraction is
6522 budget.The trick is to convince people that the quality is not
6523 compromised when you stop paying and use free software instead. That
6524 is one reason why I say the desktop experience is a weakness. People
6525 are not impressed when their USB drive doesn
't work, or their browser
6526 doesn
't play flash, for example.

>Many years ago, the
<a href=

">Skolelinux
6573 / Debian Edu project
</a
> initiated a student project to create a tool
6574 for making stop motion movies. The proposal came from a teacher
6575 needing such tool on Skolelinux. The project, called
"stopmotion
",
6576 was manned by two extraordinary students and won a school award and a
6577 national aware with this great project. The project was initiated and
6578 mentored by Herman Robak, and manned by the students Bjørn Erik Nilsen
6579 and Fredrik Berg Kjølstad. They got in touch with people at Aardman
6580 Animation studio and received feedback on how professionals would like
6581 such stopmotion tool to work, and the end result was and is used by
6582 animators around the globe. But as is usual after studying, both got
6583 jobs and went elsewhere, and did not have time to properly tend to the
6584 project, and it has been lingering for a few years now. Until last
6587 <p
>Last year some of the users got together with Herman, and moved the
6588 project to Sourceforge and in effect restarted the project under a new
6590 <a href=
"http://sourceforge.net/projects/linuxstopmotion/
">linuxstopmotion
</a
>.
6591 The name change was done to make it possible to find the project using
6592 Internet search engines (try to search for
'stopmotion
' to see what I
6593 mean). I
've been following
6594 <a href=
"https://lists.sourceforge.net/lists/listinfo/linuxstopmotion-community

>Knut Yrvin her. Jobber i Nokia med å fremme rammeverket Qt og QML
6674 med tilhørende utviklerverktøy. Rollen er som leder av
6675 friprog-samfunn. I fjor var jeg med å legge om utviklingen av Qt til
6676 åpen forvaltning. På den måten kan alle som bidrar til Qt gjøre det
6677 på like vilkår. Nå er det

">over
6679 1000 utviklere
</a

6680 forvaltning er utviklingen av Qt mer åpen enn Linux-kjernen.
</p
>
6682 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
6684 <p
>Jeg var en av initiativtagerne til Skolelinux i
2001. Skolene slet
6685 med både utstyr og Internett-tilgang. De klarte ikke å møte
6686 forventningene til data i skolen. Driften av PC-ene var uholdbar. Som
6687 regel hadde rektor pekt ut en ivrig lærer til å passe på PC-ene,
6688 gjerne naturfaglæreren. Mange lærere jobbet mye ubetalt overtid for å
6689 vedlikeholde
30-
40 datamaskiner på hver sin skole. Med
300 elever og
6690 lærere som brukere, blir det fort mye mer arbeid enn de
4-
8 timene de
6691 kunne bruke på PC-drift. Skolene hadde kun en femtedel av
6692 IT-budsjettet som ble brukt på PC-ene i rådhuset.
</p
>
6694 <p
>Vi erfarte at skolene hadde mye datautstyr som stod ubrukt. Skolene
6695 manglet penger til Microsoft-lisenser. Selv med solide skolerabatter,
6696 kostet Microsoft-lisensene gjerne like mye som PC-ene i seg selv over
6697 en periode på
5-
6 år.
</p
>
6699 <p
>Viktigheten av språklig mangfold og pedagogiske programmer var også
6700 viktig for oss. Vi oversatte mange skoleaktuelle programmer til
6701 nynorsk, nordsamisk og bokmål. Dette lenge før andre tok denne
6702 oppgaven seriøst. Allerede etter ett år hadde vi etablert et helt
6703 arsenal av skoleaktuelle programmer på nynorsk, bokmål og
6704 nordsamisk. Vi spredde vår ide om språklig mangfold til de andre frie
6705 prosjekter internasjonalt. Resultatene ser vi i mange land. Det er de
6706 frie programmene som kommer på brukernes morsmål. Det er en av flere
6707 gode grunner til at fri programvare som LibreOffice, VLC, KDE og
6708 Firefox konkurrerer ut godseid programvare mange steder i verden.
</p
>
6710 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6712 <p
>Fordelene er at Skolelinux tilbyr over
100 skoleaktuelle programmer
6713 på de norske språkene, uten ett øre i lisenskostnader. Systemet gir
6714 enormt lave driftskostnader med diskløse arbeidsstasjoner og bærbare
6715 med roaming. Skolelinux krever også mindre av maskinvaren.
</p
>
6717 <p
>Man kan fint kjøre systemet med
512 MB RAM på en bærbar PC sammen
6718 med en nettvideo i nettleseren og en presentasjon med
6719 LibreOffice. Konkurrerende system krever fort
2 GB RAM for å få til
6720 noe tilsvarende uten at det går ufattelig tregt. Skal man gjøre noe
6721 nyttig, krever konkurrentene til Linux mye større harddisk. Skoler har
6722 rapportert at de fort har fått
50% flere nye maskiner om de velger
6723 Linux. Dette i tillegg til de årlige besparelsene ved å unngå
6724 lisensbetaling til godseid programvare.
</p
>
6726 <p
>De lave driftskostnadene gjør at delstater i Europa har titusener
6727 av datamaskiner med Skolelinux i skolen. F.eks. er det under ti
6728 personer som drifter
70.000 PC-systemer i skolene i Extremadura i
6729 Spania. Det er slett ikke uvanlig at norske kommuner har
1500-
2000
6730 datamaskiner med Skolelinux. Driften tar ett årsverk. Slår flere
6731 kommuner seg sammen, kan de få samme sentraliserte stordriftsfordeler
6732 som delstater i Tyskland og Spania. Delstater som kjører Skolelinux
6733 på alle skolene. Bare noen få personer sentraldrifter titusenvis av
6736 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6738 <p
>Den største ulempen for Skolelinux er motstand mot Linux fra
6739 IT-sjefer i det offentlige. Dette er ledere som holder innlegg som
6740 snytt ut av evangelist-håndboka til Microsoft. Dette gjøres i ett
6741 arbeidsmarked med stor vekst i etterspørselen etter Linux-fagfolk i
6742 privat sektor. Etterspørselen har økt mer enn noe annet tekniske yrke
6743 siste tiåret. Åtte av ti ledere vil ansette Linux-fagfolk i
2012,
6744 rapporterer jobbnettstedet Dice.com på oppdrag av Linux
6745 Foundation.
</p
>
6747 <p
>Det mangler
16.000 ingeniører og IKT-fagfolk i Norge rapporterte
6748 arbeids- og velferdsetaten NAV. Linux-fagfolk kan velge svært
6749 interessante jobber med alt fra apps på ledende mobilsystem laget med
6750 Linux, sky- tjenester eller web-applikasjoner. De raskest voksende
6751 teknologiselskapene i verden er ute etter Linux-fagfolk. Det være seg
6752 Amazon, Google, Facebook og IBM for å nevne noen. Linux er kritisk
6753 for å sikre veksten i markedet. Det sier seg selv at lønningene og
6754 jobbmulighetene er bedre enn for andre tekniske yrker.
</p
>
6756 <p
>Skal man lage apps for mobilen, smart-TV-en eller
6757 underholdningssystemet i bilen eller på flyet, er det Linux som
6758 gjelder. Med en slik konkurranse om Linux-kompetansen, kombinert med
6759 motstanden mot Linux hos mange IT-sjefer i offentlig sektor, så
6760 hindrer kommunene rekruttering av flere Linux- fagfolk. Skolene blir
6761 tvunget til å velge dyrere og mindre komplette IT-system. De har
6762 blitt hengende igjen slik IT var på begynnelsen av
2000- tallet. Dette
6763 fordi IT-ledere ikke har tilpasset seg markedet det siste tiåret.
</p
>
6765 <p
>Når det er sagt, er Skolelinux svært enkelt å lære seg også for de
6766 som ikke kan. Det viser alle lærerne som drifter systemet for
6767 hundrevis og tusenvis av systemer. Det meste er på plass rett ut av
6768 boksen. I tillegg er det solid med dokumentasjon med god hjelp på
6769 nettet. Det er mange kommuner som har ansatt en lærer som først lærte
6770 Skolelinux på sin skole, for så å drifte alle PC-ene i kommunen med
6771 Skolelinux. Det kan fort være snakk om
1000-
3000 datamaskiner på
10-
15
6772 skoler som sentraldriftes med en stilling. Står man ordentlig fast,
6773 kan man også kjøpe profesjonell hjelp fra selskap som støtter
6774 Skolelinux. Det er flere slike selskap i Norge og i utlandet.

>Qt SDK, LibreOffice, Firefox, VLC og KDE-skrivebordet. Dette på et
6779 Debian-basert GNU/Linux-system. Jeg bruker også noen morsomme
6780 3D-spill. Idag kan jeg velge mellom over
30.000 Linux-programmer. Det
6781 finnes ikke tid i livet å undersøke alle valgmulighetene. Derfor er
6782 det bra med Skolelinux i skolen, da utvalget av programmer er
6783 begrenset til hva som er aktuelt i skolefagene.

6837 <p
>Jeg kom i kontakt med prosjektet i
2009, da jeg ble ansatt i
6838 stiftelsen Åpne kontorprogram på norsk for å oversette og teste den
6839 norske utgaven av OpenOffice.org. Arbeidet har hele tiden vært

6846 <p
>Skolelinux handler i likhet med utdanningssektoren om å dele
6847 kunnskap med andre, og det er dette som er hovedstyrken til
6848 prosjektet. Selv om Skolelinux hovedsaklig er involvert i utvikling
6849 av programvare, er det også et sted der man kan utfolde seg uavhengig
6850 av bakgrunn og ferdigheter.

6854 <p
>Liten utbredelse og manglende støtte fra leverandører som leverer
6855 pedagogisk programvare til skolebruk. Kunne kanskje hatt flere
6856 verktøy som letter administrasjonen ytterligere, slik at også mindre

6864 hvis jeg skal dra fram noen flere eksempler så er nok Mozilla Firefox

>Vi må få leverandører av pedagogisk programvare med på laget, men
6874 også utvikle vår egen tilpasset det norske markedet. Det er også
6875 mulig å involvere utdanningssektoren direkte i arbeidet, for eksempel
6876 gjennom studentprosjekter der elevene selv er med å utforme
6877 programvare direkte eller indirekte gjennom aktive bidrag. Dette gjør
6878 ikke bare samarbeidet tettere, men fokuset på standarder og friheten
6879 til å velge sin egen løsning vil kanskje stimulere interessen for
6880 framtidig deltakelse i bransjen. Vi som driver med fri og åpen
6881 programvare ønsker oss ikke rene konsumenter, men tenkende og
6882 selvstendige individer som kan være med å skape sin egen fremtid.

>New in the Squeeze version of
6892 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> is the
6893 ability for clients to automatically configure their proxy settings
6894 based on their environment. We want all systems on the client to use
6895 the WPAD based proxy definition fetched from
<tt
>http://wpad/wpad.dat
</tt
>, to
6896 allow sites to control the proxy setting from a central place and make
6897 sure clients do not have hard coded proxy settings. The schools can
6898 change the global proxy setting by editing
6899 <tt
>tjener:/etc/debian-edu/www/wpad.dat
</tt
> and the change propagate
6900 to all Debian Edu clients in the network.
</p
>
6902 <p
>The problem is that some systems do not understand the WPAD system.
6903 In other words, how do one get from a WPAD file like this (this is a
6904 simple one, they can run arbitrary code):
</p
>
6906 <blockquote
><pre
>
6907 function FindProxyForURL(url, host)
6909 if (!isResolvable(host) ||
6910 isPlainHostName(host) ||
6911 dnsDomainIs(host,
".intern
"))
6912 return
"DIRECT
";
6914 return
"PROXY webcache:
3128; DIRECT
";
6916 </pre
></blockquote
>
6918 <p
>to a proxy setting in the process environment looking like this:
</p
>
6920 <blockquote
><pre
>
6921 http_proxy=http://webcache:
3128/
6922 ftp_proxy=http://webcache:
3128/
6923 </pre
></blockquote
>
6925 <p
>To do this conversion I developed a perl script that will execute
6926 the javascript fragment in the WPAD file and return the proxy that
6928 <tt
><a href=
"http://www.debian.org/
">http://www.debian.org/
</a
></tt
>,
6929 and insert this extracted proxy URL in
<tt
>/etc/environment
</tt
> and
6930 <tt
>/etc/apt/apt.conf
</tt
>. The perl script wpad-extract work just
6931 fine in Squeeze, but in Wheezy the library it need to run the
6932 javascript code is
<a href=
"http://bugs.debian.org/
631045">no longer
6933 able to build
</a
> because the C library it depended on is now a C++
6934 library. I hope someone find a solution to that problem before Wheezy
6935 is frozen. An alternative would be for us to rewrite wpad-extract to
6936 use some other javascript library currently working in Wheezy, but no
6937 known alternative is known at the moment.
</p
>
6939 <p
>This automatic proxy system allow the roaming workstation (aka
6940 laptop) setup in Debian Edu/Squeeze to use the proxy when the laptop
6941 is connected to the backbone network in a Debian Edu setup, and to
6942 automatically use any proxy present and announced using the WPAD
6943 feature when it is connected to other networks. And if no proxy is
6944 announced, direct connections will be used instead.
</p
>
6946 <p
>Silently using a proxy announced on the network might be a privacy
6947 or security problem. But those controlling DHCP and DNS on a network
6948 could just as easily set up a transparent proxy, and force all HTTP
6949 and FTP connections to use a proxy anyway, so I consider that
6950 distinction to be academic. If you are afraid of using the wrong
6951 proxy, you should avoid connecting to the network in question in the
6952 first place. In Debian Edu, the proxy setup is updated using dhcp and
6953 ifupdown hooks, to make sure the configuration is updated every time
6954 the network setup changes.
</p
>
6956 <p
>The WPAD system is documented in a
6957 <a href=
"http://tools.ietf.org/html/draft-ietf-wrec-wpad-
01">IETF
6958 draft

6988 med brukte jeg først Mandrake og så Debian. Og siden jeg oppdaget at

7006 svare så detaljert rundt ulempene med Skolelinux. Hovedårsaken til at
7007 jeg bruker Kubuntu er nok at da vi begynte med det mener jeg det ikke
7008 var noen annen løsning. «Vandrende arbeidsstasjon» mener jeg ikke
7009 fantes da. Dessuten ville jeg ha siste versjon, da den KDE-versjonen
7010 som var i Skolelinux den gangen var en god del enklere (tror det var

7050 <description><p
>Since the Lenny version of
7051 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>, a
7052 feature to save power have been included. It is as simple as it is
7053 practical: Shut down unused clients at night, and turn them on again
7054 in the morning. This is done using the
7055 <a href=
"http://packages.qa.debian.org/s/shutdown-at-night.html
">shutdown-at-night
</a
> Debian package.
</p
>
7057 <p
>To enable this feature on a client, the machine need to be added to
7058 the netgroup shutdown-at-night-hosts. For Debian Edu, this is done in
7059 LDAP, and once this is in place, the machine in question will check
7060 every hour from
16:
00 until
06:
00 to see if the machine is unused, and
7061 shut it down if it is. If the hardware in question is supported by
7063 <a href=
"http://packages.qa.debian.org/n/nvram-wakeup.html
">nvram-wakeup
</a
>
7064 package, the BIOS is told to turn the machine back on around
07:
00 +-
7065 10 minutes. If this isn
't working, one can configure wake-on-lan to
7066 try to turn on the client. The wake-on-lan option is only documented
7067 and not enabled by default in Debian Edu.
</p
>
7069 <p
>It is important to not turn all machines on at once, as this can
7070 blow a fuse if several computers are connected to the same fuse like
7071 the common setup for a classroom. The nvram-wakeup method only work
7072 for machines with a functioning hardware/BIOS clock. I
've seen old
7073 machines where the BIOS battery were dead and the hardware clock were
7074 starting from
0 (or was it
1990?) every boot. If you have one of
7075 those, you have to turn on the computer manually.
</p
>
7077 <p
>The shutdown-at-night package is completely self contained, and can
7078 also be used outside the Debian Edu environment. For those without a
7079 central LDAP server with netgroups, one can instead touch the file
7080 <tt
>/etc/shutdown-at-night/shutdown-at-night
</tt
> to enable it.
7081 Perhaps you too can use it to save some power?

7113 disabled queues are restarted every hour. This should cut down on
7114 the amount of manual administration needed for printers.

7116 <li
>The set of initial users have been changed. Now a personal user
7117 for the local system administrator is created during installation
7118 instead of the previously created localadmin and super-admin users,
7119 and this user is granted administrative privileges using group
7120 membership. This reduces the number of passwords one need to keep
7121 up to date on the system.

>With some computer hardware, one need non-free firmware blobs.
7144 This is the sad fact of todays computers. In the next version of
7145 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> based
7146 on Squeeze, we provide several scripts and modifications to make
7147 firmware blobs easier to handle. The common use case I run into is a
7148 laptop with a wireless network card requiring non-free firmware to
7149 work, but there are other use cases as well.
</p
>
7151 <p
>First and foremost, Debian Edu provide ISO images for DVD and CD
7152 with all firmware packages in the Debian sections main and non-free
7153 included, to ensure debian-installer find and can install all of them
7154 during installation. This take care firmware for network devices used
7155 by the installer when installing from from local media. But for
7156 example multimedia devices are not activated in the installer and are
7157 not taken care of by this.
</p
>
7159 <p
>For non-network devices, we provide the script
7160 <tt
>/usr/share/debian-edu-config/tools/auto-addfirmware
</tt
> which
7161 search through the
<tt
>dmesg
</tt
> output for drivers requesting extra
7162 firmware. The firmware file name is looked up in the Contents-ARCH.gz
7163 file available in the package repository, and the packages providing
7164 the requested firmware file(s) is installed. I have proposed to do
7165 something similar in debian-installer (BTS report
7166 <a href=
"http://bugs.debian.org/
655507">#
655507</a
>), to allow PXE
7167 installs of Debian to handle firmware installation better. Run the
7168 script as root from the command line to fetch and install the needed
7169 firmware packages.

7175 initrd with extra firmware, the
7176 <tt

7183 provided to update the LTSP initrd with firmware blobs. It is used
7184 the same way as the other firmware related tools.

7246 <description><p
>The next version of
<a href=
"http://www.skolelinux.org/
">Debian Edu
7247 / Skolelinux
</a
> will include a new tool
7248 <tt
>sitesummary2ldapdhcp
</tt
>, which can be used to quickly set up all
7249 the computers in a school without much manual labour. Here is a short
7250 summary on how to use it to set up a new school.
</p
>
7252 <p
>First, install a combined Main Server and Thin Client Server as the
7253 central server in the network. Next, PXE boot all the client machines
7254 as thin clients and wait
5 minutes after the last client booted to
7255 allow the clients to report their existence to the central server. When
7256 this is done, log on to the central server and run
7257 <tt
>sitesummary2ldapdhcp -a
</tt
> in the
<tt
>konsole
</tt
> to use the
7258 collected information to generate system objects in LDAP. The output
7259 will look similar to this:
</p
>
7261 <p
><blockquote
><pre
>
7262 % sitesummary2ldapdhcp -a

7266 Enter password if you want to activate these changes, and ^c to abort.
7268 Connecting to LDAP as cn=admin,ou=ldap-access,dc=skole,dc=skolelinux,dc=no
7269 enter password: *******
7271 </pre
></blockquote
></p
>
7273 <p
>After providing the LDAP administrative password (the same as the
7274 root password set during installation), the LDAP database will be
7275 populated with system objects for each PXE booted machine with
7276 automatically generated names. The final step to set up the school is
7277 then to log into
<a href=
"https://oss.gonicus.de/labs/gosa/
">GOsa
</a
>,
7278 the web based user, group and system administration system to change
7279 system names, add systems to the correct host groups and finally
7280 enable DHCP and DNS for the systems. All clients that should be used
7281 as diskless workstations should be added to the workstation-hosts
7282 group. After this is done, all computers can be booted again via PXE
7283 and get their assigned names and group based configuration
7284 automatically.
</p
>
7286 <p
>We plan to release beta3 with the updated version of this feature
7287 enabled this weekend. You might want to give it a try.
</p
>
7289 <p
>Update
2012-
01-
28: When calling sitesummary2ldapdhcp to add new
7290 hosts, one need to add the option -a. I forgot to mention this in my
7291 original text, and have added it to the text now.

>I serien med intervjuer av folk i
7301 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet, har jeg nå
7302 lyktes med å få tak i en skolemann som ikke er aktiv med utviklingen,
7303 men likevel har vært med nesten siden starten av prosjektet. Jeg
7304 ønsker derfor velkommen til Paul Reidar Løsnesløkken, en mann med
7305 mange års erfaring i bruk av Skolelinux.
</p
>
7307 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
7309 <p
>Jeg driftet tidligere IKT løsningen for skolene i
7310 <a href=
"http://www.nord-odal.kommune.no/
">Nord-Odal
</a
>. I dag er jeg
7311 IKT-konsulent for hele kommunen og samarbeider med
7312 <a href=
"http://www.hedmarken-ikt.no/
">Hedmark-IKT
</a
> for best mulig
7313 tjenester til kommunen. Jeg har bakgrunn som elektronikkreparatør og
7314 grunnskolelærer og har tatt en del fag innen IKT, i hovedsak
7315 driftsfag. IKT i Nord-Odal kommune blir i dag driftet av Hedmark IKT
7316 som er et samarbeid mellom Løten, Stange, Grue, Hamar, Kongsvinger og
7317 Nord-Odal. Jeg er fortsatt
"IKT-personen
" på skolene i kommunen og
7318 følger opp og gjør enkelte mindre endringer der.
</p
>
7320 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
7322 <p
>Kommunen satset på Skolelinux i
2004. Jeg var ikke med i
7323 beslutningsprosessen den gang, men ble likevel med fra starten når
7324 dette ble levert.
</p
>
7326 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7328 <p
>Fordelene med Skolelinux er rask oppstart, sentral drift av
7329 klientene, klienter som jobber raskt og effektivt, bedre
7330 funksjonalitet på eldre utstyr og en ganske god programpakke med fri
7331 programvare som følger med. Løsningen med halvtykke klienter gjør at
7332 prosessering skjer lokalt med alltid ferske maskiner.
</p
>
7334 <p
>Skolelinux kan fungere godt på gammelt utstyr, men det er klart at
7335 utstyr også blir for gammelt selv for Skolelinux. I forbindelese med
7336 at vi nylig fikk nye servere og ny installasjon kastet jeg ut ca
60
7337 klienter som fortsatt var i drift etter at de var kjøpt godt brukt i
7338 2004. Noe var rundt
15 år gammelt, men var fortsatt i bruk. Noen
7339 klaget på at det nå gikk veldig tregt på en del pedagogiske nettsider
7340 med flash o.l. Det er fullt forståelig.
</p
>
7342 <p
>Jeg fikk nylig et spørsmål fra ungdomsskolens rektor om jeg kunne
7343 legge inn
<a href=
"http://freemind.sourceforge.net/
">FreeMind
</a
>, et
7344 tankekartprogram , på skolens elev-Windowsmaskiner. Lærerne hadde
7345 vært på kurs og ville ta dette i bruk. Skolen har ca halvparten av
7346 elevmaskinene på bærbare Windowsmaskiner. Da kunne jeg fortelle at
7347 dette programmet allerede lå inne på den nye Skolelinuxløsningen
7348 som nettopp var satt i drift, klart til bruk.
</p
>
7350 <p
>Vi har de bærbare maskinene på ungdomsskolen i domene med
7351 Skolelinux. Dette fungerer også meget bra nå. Elevene får opp en
7352 midlertidig windowsprofil når de logger på. Denne profilen slettes
7353 etter at de logger av, noe som medfører rene profiler hver gang de
7354 starter opp en maskin. De må lagre i sin Skolelinprofil, noe som
7355 medfører at de får tak i sine filer uavhengig av om de starter en
7356 Windowsmaskin eller en Skolelinuxklient. Det er mye mindre trafikk i
7357 det trådløse nettet etter at ikke hele profiler blir lastet opp til de
7358 enkelte Windowsmaskinene og tilbake når man avslutter. Jeg vet ikke om
7359 dette er standardoppsett i Skolelinux, men slik er vårt oppsett
7362 <p
>Vi har i flere år satt opp vår løsning slik at skriverkøer slettes
7363 og skrivere startes hver natt. Hyggelig å høre at dette nå skal bli
7364 en standard i Skolelinuxløsningen. Dette har vært en god hjelp for
7367 <p
>Elevene er lite opptatt av om de jobber på en Skolelinux eller en
7368 Windowsmaskin bare de har de programmene de trenger og at det virker
7369 når det skal brukes. Vi kjører mest mulig de samme programmene på
7370 Windows som i Skolelinux, som f.eks Audacity og LibreOffice.
</p
>
7372 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7374 <p
>Lærere bruker hos oss Windows. Dette fordi de da selv har mer
7375 kontroll over sin maskin, kan bruke den overalt, og kan legge inn
7376 programmer selv når de trenger noe i forhold til kurs o.l de er
7377 på. Jeg tror lærernes selvstendighet her gjør dem tryggere på IKT-bruk
7378 generelt. Det at de av og til får opp advarsler og lignende gjør også
7379 at de må tenke igjennom og spørre om ting rundt datasikkerhet.
</p
>
7381 <p
>Det er en del programmer vi bruker som ikke finnes for Linux. Mest
7382 brukt er nok Photostory3 som brukes i mange sammenhenger, særlig på
7383 ungdomsskolen, bl.a. til å lage herbarier (plantesamling) . Dette
7384 finnes gratis for Windows, men er ikke fri programvare. Vi er opptatt
7385 av at programmer elevene bruker på skolen også kan brukes gratis
7386 hjemme. Det er også en del programmer som brukes til spesielle elever
7387 som bare går i Windows. Det er viktig med fokus på funksjoner og ikke
7388 på hvilket OS man bruker.
</p
>
7390 <p
>For oss er det kombinasjonen mellom Skolelinux og Windows som gir
7391 oss en god og hel løsning. Skolelinux er best der de er gode.
</p
>
7393 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
7395 <p
>Selv er det LibreOffice jeg bruker til daglig. Jeg bruker selv en
7396 Windowsmaskin. Jeg har benyttet en del fri programvare i forbindelse
7397 med sjekking av trafikk i nettverk, slik som Wireshark, men dette er
7398 jo ikke aktuelt for skolene. Jeg er generelt glad i programmer som
7399 fungerer på både Linux og Windows og gjerne MAC.
</p
>
7401 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
7402 skoler til å ta i bruk fri programvare?
</strong
></p
>
7404 <p
>Det er viktig at det benyttes programmer som elevene også kan ta i
7405 bruk hjemme. Det skal da være enkelt, lovlig og gratis for
7406 elevene. Da er jeg ikke lenger veldig opptatt av om det kalles
"fri
7407 programvare
". For skolene tror jeg
"gratis
" og
"funksjonelt
" er bedre
7408 begreper enn
"fri
" i forhold til programmer. De fleste skiller nok
7409 ikke mellom
"fri

>During christmas, I have been working getting the next version of
7467 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> ready
7468 for release. The initial problem I looked at was particularly
7469 interesting.
</p
>
7471 <P
>The installer would hang at the end when it was doing it
7472 post-installation configuration, and whatevery I did to try to find
7473 the cause and fix it always worked while I tested it, but never when I
7474 integrated it into the installer and ran the installation from
7475 scratch. I would try to restart processes, close file descriptors,
7476 remove or create files, and the installer would always unblock and
7477 wrap up its tasks.
</p
>
7479 <p
>Eventually the cause was found. The kernel was simply running out
7480 of entropy, causing the Kerberos setup to hang waiting for more.
7481 Pressing keys was adding entropy to the kernel, and thus all my tries
7482 to fix the problem worked not because what I was typing to fix it, but
7483 because I was typing.
</P
>
7485 <p
>The fix I implemented was to add a background process looking at
7486 the level of entropy in the kernel (by checking
7487 /proc/sys/kernel/random/entropy_avail), and if it was too small, the
7488 installer will flush the kernel file buffers and do
'find /
' to
7489 generate some disk IO. Disk IO generate entropy in the kernel, and is
7490 one of the few things that can be initated from within the system to
7491 generate entropy.

>Etter en lang pause er det klart for neste mann ut i min serie med
7508 <a href=

">Skolelinux
</a

7510 Denne gangen har jeg besøk av et avtroppende styremedlem i
7511 <a href=
"http://www.friprogramvareiskolen.no/
">FRISK
</a
>, og en mann
7512 som har vært aktiv i Linux-miljøet i Bergen siden
90-tallet.
</p

7514 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
7516 <p
>Jeg heter Peter Hansteen, og jobber til daglig som seniorkonsulent
7517 i EDB ErgoGroup i Bergen. I praksis betyr det systemadministrasjon på
7518 Unix (primært Solaris, men en viss komponent av Linux). Men Solaris
7519 er for meg et relativt nytt bekjentskap, hovedplattformen min har
7520 generelt vært OpenBSD og til dels FreeBSD.
</p

7522 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
7524 <p
>Jeg husker ikke helt alle detaljene mer ;) - men jeg tror det var
7525 gjennom news-gruppen no.it.os.unix.linux.diverse, efn-listen og
7526 etterhvert også BLUG-miljøet her i Bergen. Vi hadde et par
7527 Skolelinux-sentrerte BLUG-møter for noen år siden, og det har vært et
7528 par Skolelinux-utviklersamlinger her.
</p
>
7530 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7532 <p
>Jeg bruker dessverre ikke Skolelinux daglig. Men slik jeg kjenner
7533 prosjektet har det vært i stand til å ta opp i seg det beste av fri
7534 programvare i mange kategorier, så fra et sysadmin-perspektiv ser det
7535 ut som en svært behagelig sak. For brukerne er det vel både en fordel
7536 og en ulempe at det ikke er Windows. Men vi håper at fordelene med et
7537 fritt system etterhvert vil bli åpenbare for både elever, lærekrefter
7538 og foreldre.
</p
>
7540 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7542 <p
>Vel, ulempen er vel først og fremst at andre aktører med mer
7543 kapitalmuskel har klart å etablere seg som det både lærere og foreldre
7544 føler seg trygge på, selv om det etter mitt hode ikke er noen grunn
7545 til å være spesielt trygg på de kommersielle alternativene.
</p
>
7547 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
7549 <p
>Når jeg får bestemme helt selv, bruker jeg kun fri programvare. Da
7550 helst med vekt på ting som kjører greit på OpenBSD. Hjemme er det
7551 OpenBSD, Ubuntu eller FreeBSD vi bruker. På skrivebordet er det en
7552 avveining mellom Gnome, KDE eller hva-det-nå-heter som er
7553 standardvalget i Ubuntu, ellers er det de kjente tingene som
7554 LibreOffice, Emacs, mplayer. På server er det selvfølgelig Apache,
7555 for overvåking både OpenNMS og Nagios (det bare ble sånn, og
7556 forskjellige siter). Jeg skriver til tider om slikt jeg holder på med
7558 <a href=
"http://bsdly.blogspot.com
">http://bsdly.blogspot.com
</a
>.
</p
>
7560 <p
>Men vi må nevne at selv vi har en Microsoft-ting som vi slår på når
7561 vi av en eller annen grunn må. Det betyr igjen vanligvis når en
7562 mobiltelefon eller en annen lukket elektronisk dings krever kontakt
7563 via en slik for å få oppdateringene sine.
</p
>
7565 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
7566 skoler til å ta i bruk fri programvare?
</strong
></p
>
7568 <p
>Hadde vi hatt det rette svaret på det spørsmålet, så hadde vi
7569 gjerne hatt Skolelinux som førstevalg på alle skoler ;)
</p
>
7571 <p
>Men jeg tror vi må legge vekt på flere forskjellige ting. En helt
7572 sentral sak er å fokusere på fri programvare og åpne standarder som de
7573 demokratiske verdiene de faktisk er. Det har kanskje kommet litt for
7574 mye i bakgrunnen i forhold til strevet etter å lage det mest mulig
7575 'brukervennlige
' systemet. Det er en tung vei å gå, så det er
7576 forståelig at freenix-aktivister heller velger å skrive kode og annet
7577 som er mer lystbetont. Mer praktisk tror jeg vi må gjøre i alle fall
7578 to ting: For det første sørge for å fortsette med å levere det best
7579 mulige frie produktet, slik at det er lett å både komme i gang og
7580 holde systemene i daglig drift, og for det andre
2) spore opp mulige
7581 aktivister der de finnes, via lokale brukergrupper, sosiale medier
7582 eller annet og sørge for at de fortsetter å være aktive. Mer og
7583 mindre uformelle treff kan være nyttig i tillegg til de mer
7584 organiserte møtene med foredrag, konferanser og utviklersamlinger.

7601 <p
>Mitt navn er Frode Jemtland, og jeg jobber i Hedmark IKT, som er et
7602 driftsselskap for Grue, Hamar, Kongsvinger, Løten, Nord-Odal og Stange
7603 kommuner. Her er jeg leder for avdelingen Løsninger og Arkitektur. Vi

7607 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
7609 <p
>Jobbet i IBM fra
2000, og da spesielt med Linux. Dette var da et av
7610 de mest tydelige linux prosjektene i Norge, og her ønsket jeg å
7611 bidra. Var aktivt med i prosjektet i
4-
5 år.
</p
>
7613 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7615 <p
>Fordelene slik jeg ser det er den sentraliserte driftmodellen, og
7616 alle de vel gjennomtenkte løsningene som er inkludert i denne
7617 løsningen. Samtidig er det basert på en stabil, og godt kjent
7618 plattform. Dette vil si at man har en løsning som skal være mye
7619 tilgjengelig, og hvor det er relativt enkelt å få tak i personer som
7620 kan mye om den grunnleggende plattformen.
</p
>
7622 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7624 <p
>De største utfordringene med en løsningen er at den er intensiv på f.eks
7625 nettverk. I seg selv ikke et problem for en enkelt skole, men skal løsningen
7626 kjøres i større skala, med sentraliserte servere, så gir dette noen
7627 utfordringer.
</p
>
7629 <p
>Utifra hva jeg har sett på større installasjoner så er det ikke så
7630 enkelt å skjønne, hva som bør gjøres for at den skal skaleres opp, og
7631 da ta godt vare på alle sider av dette, ikke bare mer server å fordele
7632 last/trykk, men hvordan også beholde robustheten og fleksibiliteten i
7633 løsningen.
</p
>
7635 <p
>En annen utfordring er at stadig flere produkter som skal brukes i
7636 skoleløsningen ikke er laget til å kunne brukes i en
7637 skolelinuxløsning. Det blir derfor fort mye skreddersøm i de
7638 forskjellige installasjonene, for å få diverse pedagogiske programmer,
7639 webløsninger, smartboards, m.m. til å fungere. Man er også en for
7640 liten kundebase til at leverandørene ønsker å gjøre noe med
7641 utfordringen. Problemet overlates til oss.
</p
>
7643 <p
>Det er også en kontinuerlig utfordring rundt problemet med å holde
7644 programvare på stabile versjoner, kontra å få ny funksjonalitet. Dette
7645 er jo en konflikt mellom oss som ønsker å drifte en stabil, og
7646 kostnadseffektiv løsning, mot sluttbrukerne som ønsker seg funksjoner
7647 det er vant med fra andre løsninger, eller som de må ha for at et
7648 eller annet nytt produkt skal fungere i løsningen. Dette er en
7649 utfordring også for andre plattformer.
</p
>
7651 <p
>En siste utfordring som ikke har noe med løsningen å gjøre, men med
7652 det omkringliggende miljøet denne skal kjøre i, er at de enhetene som
7653 skal drifte dataløsninger for kommuner og fylkeskommuner begynner å
7654 profesjonaliseres, og er da avhengig av å ha standard løsninger for å
7655 drifte store brukermasser. MS er selvsagt klar over dette, og har jo
7656 nå flere områder de begynner å bli veldig dominerende på. Den største,
7657 og mest problematiske er katalogtjenesten. Man får snart ikke tak i
7658 større løsninger som ikke krever en AD. Når man da har store enheter
7659 som drifter både kommunalt ansatte og skoler, så vil det være et
7660 stordriftargument å standardisere på en katalog tjeneste, og da har
7661 man ikke noe valg. Her er alle slike driftsenheter for små til å få
7662 gjort om på dette. Her burde konkurransemyndighetene kommet på
7663 banen. Men konkurransetilsynet i USA griper sjeldent (og ikke før det
7664 har gått veldig lang tid) inn i monopolsituasjoner så lenge
7665 monopolisten er et amerikansk firma, så da har vel ikke andre
7666 myndigheter så mye de skulle ha sagt....

><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
7670 <p
>Privat kjører jeg Debian på alle mine datamaskiner. Det gjør jeg
7671 også på min jobbmaskin. Vi har også
15-
20 linux servere av typene
7672 SuSE, Debian, Redhat, CentOS m.m. Jeg bruker derfor mye fri
7673 programvare. Av enkelt programmer kan sikkert masse nevnes. Hvis vi
7674 skal begrense oss til daglig, så må jeg si: OpenOffice, Firefox,
7675 Kontact, Kopete, Amarok,
7676 <a href=
"http://gramps-project.org/
">Gramps
</a
>, Kate, ssh, bash,
7677 rsync, backuppc m.m.

>
7679 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
7680 skoler til å ta i bruk fri programvare?
</strong
></p
>
7682 <p
>Det er et godt spørsmål, som jeg har lurt på selv.
</p
>
7684 <p
>Argumentene som ofte har vært brukt om at ting koster mindre holder
7685 ikke mål når man ser på hva som faktisk koster penger. Det er de
7686 ansatte som er en kostnadsdriver. Det vil si at hvis man har et system
7687 som den ansatte kan, så vil en kostnad på dette systemet kunne
7688 forsvares ganske mye ved at den ansatte gjør dette raskere og
7689 effektivt. Også uten å måtte eventuelt leie inn folk.
</p
>
7691 <p
>Jeg syns det er viktigere å fokusere på prinsippet med å velge fri
7692 programvare, men det er også et felt hvor man fort møter lite
7693 forståelse blant de ansatte i skolen.
</p
>
7695 <p
>Her må nok strategien fortsette å være at de sentrale myndighetene
7696 må sende tydelige signaler for hva de ønsker at offentlige enheter
7697 skal gjøre. Det var mye positivt på gang ang. dette for et par år
7698 siden. Både med eNorge og eKommune planene, men dette syns jeg har
7699 stoppet opp. En del av dette kan jo kanskje være usikkerheten som
7700 etter hvert har blitt, når man har sett kompleksiteten i de
7701 prosjektene som har blitt igangsatt. Det har også blitt noe usikkerhet
7702 i markedet ref. Sun, Oracle, Novell, Microsoft m.m. Samtidig har jo
7703 også de proprietære programleverandørene sørget for å endre sine
7704 lisenser slik at man uansett ikke slipper unna kostnaden til deres
7705 produkter, selv om man skulle velge alternativer. Da er det økonomiske
7706 argumentet, som jeg nevnte tidligere, spilt ganske godt ut over
7707 sidelinjen.

7731 hadde vel hørt om prosjektet i media før en gjeng i Trondheim startet
7732 opp SPIST, Skolelinux-prosjektet i Sør-Trøndelag, hvor vi hjalp noen
7733 skoler i nærområdet med å installere Skolelinux og finne brukt
7734 IT-utstyr til disse. Det var moro å gjøre noe praktisk for å spre
7735 Skolelinux, og å se hvor fort gjort det var å sette opp utrangerte
7736 klientmaskiner og få disse opp som tynnklienter på helt nye datasaler
7737 på skolene, kun med kostnaden til servere.

7739 <p

7741 <p
>Det er et system spesielt skreddersydd for drift av et stort antall

7743 er enkelt og billig å installere og drifte, og det trenger ikke ny

7750 litt gammel programvare pga. at den følger Debian sine utgivelser.

7768 fleksibilitet, åpenhet og ikke låsing til en leverandør framfor sparte
7769 lisenskostnader, samt programvarens kvalitet og fortrinn, og at den
7770 fritt kan brukes på et ubegrenset antall PC-er, også hjemme hos
7771 elevene. En bør også forbedre den fri programvaren ved testing,
7772 bugrapportering og kodebidrag om man kan, og ikke anbefale programvare
7773 uten at man har forsikret seg at den har tilstrekkelig kvalitet,
7774 ellers kan man lett oppnå det motsatte. Tror en bør selge inn
7775 konseptet til fylkes-/statsnivå, kanskje med bidrag til
7776 utviklingsarbeid fra disse som alle landets skoler kan få glede

7787 og ildsjel på Harestad skole tok kontakt og fortalte at de bruker
7788 Linux på sin skole, og lurte på om de kunne bidra til å gjøre
7789 fordelene kjent. Riktig nok bruker de ikke

7791 men jeg synes dette er en god anledning til å gjøre flere fasetter
7792 rundt Linux-økosystemet kjent, og tok et lite intervju.

7802 <p
>I
2002 begynte daværende IKT-ansvarlige og jeg et arbeid på skolen
7803 med å gå over fra Win98 til... noe annet. Vi testet en rekke
7804 forskjellige løsninger, deriblant Skolelinux, men endte opp med
7805 RedHat. Skolelinux var den gang ikke modent for det vi ville ha. Jeg
7806 har siden fulgt jevnlig med på hva skolelinux holder på med, men har
7807 hele tiden vært bedre fornøyd med vår egen
"standardiserte
" løsning på
7808 RedHat/CentOS og Fedora. Vi snuser for tiden på Ubuntu som løsning på
7809 klientsiden.
</p
>
7811 <p
>I dag har vi på skolen vår en større linux-løsning med
400 klienter
7812 som kjører en blanding av LTSP (tynnklient) og DRBL (tykk klient uten
7813 harddisk) med en masse tjenere på serverrommet. Vi drifter hele
7814 sulamitten selv med webtjener, eposttjener, webmail, filtjenere,
7815 virtuelle tjenere osv. Og IT-ansvarlig har en
80% stilling som
7816 IT-ansvarlig - og så er han KoH-lærer i de resterende
20% :-)

</p

7821 <p
>For å ta brodden av frykten for at ildsjeler gjør skolen sårbar om
7822 ildsjelene falle fra, har jeg forsikret kommunen og skolesjefen i
7823 Randaberg om at det finnes godt kommersielle tjenester vi kan benytte
7824 oss av - om det skulle bli nødvendig. Vi er tre stykker i kommunen som
7825 nå har
<strong
>god
</strong
> linux-kompetanse ift. å drifte et større
7826 system. IT-avdelingen i kommunen vil ikke ta på oss med ildtang -
7827 selv om vi nok har større IT-kompetanse mot linux enn det de selv har
7828 mot windows (de kjøper en
<strong
>masse
</strong
> konsulenttjenester
7829 fra ErgoGroup).
</p
>
7831 <p
>I kvantitet er Harestad og Grødem skole tilsammen et større
7832 IT-system enn resten av Randaberg kommune + Kvitsøy og Rennesøy, som
7833 kommunen også har driftsansvar for. Vi har som sagt rundt
800
7834 maskiner, mens kommunen med sitt driftsansvar har ansvar for rundt
500
7835 maskiner. Det er selvfølgelig litt forskjell i hvor kritiske
7836 tjenestene våre er, men det gir allikevel et litt rart bilde når
7837 IT-avdelingen overhode ikke er interessert i å snakke med oss om
7838 hvordan vi gjør ting :-)
</p

7840 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7842 <p
>Fra linux-perspektivet (ikke bare Skolelinux) er det en fordel av
7843 systemet er basert på fri programvare - og dermed fritt i ordets mange
7844 betydninger. Det er alt vi trenger: stabilt, relativt enkelt å drifte
7845 (tross alt - et større windowssystem er ikke enkelt å holde live det
7846 heller), rimelig i innkjøp og drift, og sist, men ikke minst, det er
7847 moderne for sluttbruker! Linux, i sine mange varianter,
7848 <strong
>ser
</strong
> nytt ut, fordi det hele tiden blir
7849 oppdatert. Derfor lever systemet opp til hvordan elever forventer at
7850 et moderne GUI skal være (i motsetning til WinXP :-).
</p
>
7852 <p
>Vi var veldig pragmatiske da vi begynte med linux i skolen. Det var
7853 billig, det fungerte og kunne bruke alle de gamle windows-maskinene
7854 som
"nye
" tynne klienter. I dag er vi mer bevisste fri
7855 programvare-tilhengere. Vi har oppdaget hva det er - og vi liker
7858 <p
>En av de
<strong
>store
</strong
> fordelene med fri programvare er at
7859 vi kan installere tjenester vi ønsker å tilby brukerne våre - uten å
7860 måtte tenke på om vi har råd til lisensene (fordi det er ingen). Alt
7861 vi setter i produksjon er ut i fra brukernes behov og vår kapasitet
7862 til å drifte dem. Vi skreddersyr tjenestene etter behovet og dermed
7863 trenger vi ikke ende opp med å kjøpe en pakke der vi egentlig bare var
7864 interessert i en liten del av den.
</p
>
7866 <p
>Bruk av linux frigjør ikke økonomiske midler, fordi midlene til IKT
7867 i skole er for få i utgangspunktet - men vi får så
7868 <strong
>mye
</strong
> mer igjen for dem når vi bruker en linux-løsning
7869 fremfor en windows-løsning. I praksis ser vi at vi måtte ut med det
7870 dobbelte på budsjettet vårt om vi skulle hatt en tilsvarende
7871 windows-løsning, som det vi i dag drifter med linux.
</p
>
7873 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7875 <p
>Ikke all pedagogisk programvare er tilgjengelig. Det er en del
7876 programvare i skolen som er laget med utviklerverktøy som bare virker
7877 i windows, f.eks. Drillpro, LingDys/LingWrite. Det er også
7878 "programmer
" som bare virker om du har tilgang til Microsoft Office,
7879 f.eks. AskiRaski.
</p
>
7881 <p
>Vi sliter også litt med at video-codecer ikke alltid er like lett å
7882 få opp å gå på klientene. Det er alltid en eller annen videosnutt fra
7883 nrk.no som ikke er så samarbeidsvillig, uansett mediaplayer.
</p
>
7885 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
7887 <p
>Alt :-) På skolen bruker vi det som finnes og som er nyttig. Det vi
7888 bruker mest er Firefox (jobber med Chrome, fordi det er
7889 <strong
>mye
</strong
> raskere med Flash enn Firefox), OpenOffice (skal
7890 over til LibreOffice), GIMP osv. Standardpakken av
7891 sluttbrukerprogrammer.
</p
>
7893 <p
>På tjenernivå bruker vi OpenWebMail (skal over til Zimbra), Exim
7896 <p
>Personlig bruker jeg de fleste programmer over flere plattformer,
7897 men jeg har lagt meg til en vane å prioritere bruken av fri
7898 programvare også i Windows
7 og OSX.
</p
>
7900 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
7901 skoler til å ta i bruk fri programvare?
</strong
></p
>
7903 <p
>Jeg er langt i fra sikker. For det første handler det mye om at
7904 IKT-avdelingen i kommunen ofte er de som styrer hva som er IKT på
7905 skolene - og de liker å bruke avtalene med Microsoft, som de garantert
7906 har fra før. Dessuten - Select
6-avtalen til skolene gjør Microsoft
7907 skvettbillig.
</p
>
7909 <p
>Vi la vekt på effektiv drift av systemet - og at vi kunne øke
7910 antall maskiner uten å måtte øke budsjett for utstyr eller personell
7911 særlig mye, enn om vi hadde gått for en Microsoft-løsning. I praksis
7912 ser vi at en ren linux-installasjon driftes til halve prisen av en
7913 Microsoft-løsning.
</p
>
7915 <p
>Vi har i praksis også sett at det lærerne (og elevene) liker er at
7916 vi tilbyr
<strong
>veldig
</strong
> mange tjenester som ikke er så
7917 vanlige i en Microsoft-løsning. Det er ikke så vanlig at
7918 <strong
>elevene
</strong
> også har epost, hjemmekontor osv. Det har vi
7919 også brukt som et vellykket argument mot Microsoft.
</p
>
7921 <p
>Den beste måten er selvfølgelig at noen bare bestemmer
7922 det. Problemet er å få dem som har makt til å bestemme det til faktisk
7923 å gjøre det ;-)

7939 <p
>Jeg heter Astri Sletteng. Jeg er lærer og IKT veileder ved Håkvik
7940 skole i Narvik kommune. Min bakgrunn når det gjelder IKT: Av formell
7941 utdannelse har jeg lærerutdanning, Master i skoleledelse og IKT for
7942 lærere. Har jobba som IKT veileder siden
2002.
</p
>
7944 <p
>Det viktigste for meg som IKT veileder er å få fundamentert den
7945 5. basisferdigheten, digital kompetanse ved skolen min på en god måte
7946 slik at hele skolesamfunnet tar i bruk IKT i alle fag. Dette arbeidet
7947 gjøres i nært samarbeid med skolens ledelse.
</p

7949 <p
>Min viktigste jobb som IKT veileder er å være motivator og pådriver
7950 i IKT arbeidet ved skolen.

7952 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong

7954 <p
>Jobber i en kommune hvor vi satser på Fri programvare. I
2004 ble
7955 det gjort et politisk vedtak om at vi skulle innføre Skolelinux ved
7956 alle skolene i kommunen. Jeg har dermed en god del erfaring med
7957 Skolelinux, samt annen fri programvare som Open Office, Joomla, Moodle
7960 <p
><strong

7962 <p
>Siden vi jobber med åpen kildekode kan vi få programmene og
7963 produktene tilpasset vår bruk. Det er jo heller ikke en ulempe at
7964 skolen kommer bedre ut økonomisk, men først og fremst er det viktig
7965 for oss at vi har digitale systemer som gjør at vi kan følge
7966 læreplanen i alle fag. Det syns jeg at vi kan gjøre gjennom
7967 Skolelinux.
</p

7969 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p

7971 <p
>Skolen er avhengige av å ha folk på IT avdelinga i kommunen som kan
7972 drive support, og være tilgjengelige når vi trenger hjelp. Det er en
7973 ulempe at ikke alle på denne avdelingen nødvendigvis er god på
7976 <p
>Vi har også noen utfordringer når det kommer til spesielle
7977 programmer som enkelte elever er avhengige av ? og som ikke er
7978 plattform uavhengige. Her har vi i Friprog-verden, men også
7979 departement en jobb å gjøre.

7985 Moodle (innført på alle klassetrinn + som et administrativt verktøy)
7986 og Joomla som hjemmeside.

7994 <p

>Rubén Romero y Cordero,
81-modell, deltidspappa (
50%) for en jente
8013 på
6 år. Jobber i Oslo som Global Sales Executive hos Varnish Software
8014 og til daglig har jeg kontakt med kunder fra hele verden. Min
8015 forkjærlighet for fri programvare har gjort at jeg har nå flere års
8016 erfaring med salg av slike løsninger (bl.a. fra Redpill Linpro og
8017 Freecode) og mye innsikt og kunnskap om det globale IT-markedet.
8018 Ellers er jeg involvert i flere prosjekter bl.a. er jeg Ubuntu
8019 Community medlem, kontaktpersonen for Ubuntu Norge og driveren av
8020 SpreadUbuntu marketing prosjektet og nå fersk styremedlem i FRISK. Jeg
8021 har brukt GNU/Linux siden
1997.

8025 <p
>Som Debian bruker siden slutten av
90-tallet var det uunngåelig å
8026 ikke komme bort i Skolelinux. Dette var vel i slutten av
2001 når jeg
8027 var student ved UiO. Flere år senere fikk jeg lastet og testet Venus
8028 (Skolelinux
1.0) på release dagen.
</p

8030 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
8032 <p
>Fri programvare bygges sten for sten i det åpne, slik at koden og
8033 prosessen den lages på kan gjennomskues av andre enn de som har laget
8034 det. Det er et vitenskapelig og gjennomsiktig måte å lage programvare
8037 <p
>Skoler i vårt samfunn skal være steder hvor vitenskapelig kunnskap
8038 deles til alle. I dag har vi ikke et vitenskapelig tilnærming til
8039 hvordan programvaren som brukes på skolen lages. Skolelinux bringer
8040 inn at slik tilnærming i skoleverkets klasserom, siden
8041 operativsystemet er en åpent platform som gir skolene muligheten til å
8042 dra nytte av programvare som er laget av tusenvis av mennesker verden
8043 rundt og som gir elevene så vel som lærerne muligheten til å bruke,
8044 dele, forandre og forbedre OSet sitt uten begrensninger. I den
8045 forbindelsen representerer Skolelinux også konkrete resultater utfra
8046 samhandling på tvers av grenser.
</p
>
8048 <p
>Når det gjelder de tekniske fordelene av Skolelinux er jeg sikker
8049 på at andre enn meg har allerede beskrevet disse bedre enn det jeg
8050 kan. Men jeg kan likevel tilføye noe: Skolelinux som sådan er en
8051 community-drevet operativsystemplatform. Som i ethvert
8052 community-prosjekt har alle Skolelinux brukere muligheten til å
8053 påvirke retning av prosjektet og resultatet som gjenspeiles i
8054 programvaren. Dette kommer sjeldent frem og jeg mener at det er noe
8055 som burde fokuseres mer på.
</p

8057 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong

8059 <p
>De største ulempene er:
</p
>
8062 <li
>Mangel på kompetanse
</li
>
8063 <li
>Mangel av administrative verktøy som kunne hjelpe lokale IT
8064 avdelinger å bruke Skolelinux til mer enn bare en tjener for
8065 terminalklienter. Et eksempel: Zentyal sin web-dashboard.
</li
>
8068 <p
>Bedre og mer intuitive administrative verktøy kunne løst deler av
8069 problemet, men det er unektelig at ved bruk av Skolelinux må
8070 IT-personalet vite hva de gjør for å få ting gjort riktig, eller i det
8071 hele tatt. Med andre platformer er kompetansen enklere tilgjengelig og
8072 løsningene kan fungere på en tilfredstillende, om ikke riktig

</strong

8115 <p
>Skolelinux har jeg møtt ved flere anledninger opp gjennom åra, både gjennom
8116 entusiastiske skolelinuxbrukere og skeptiske
"forståsegpåere
" :-)
</p
>
8118 <p
>Jeg husker en leverandør av et stort OS for noen år siden mente at
8119 Skolelinux var kun for hackere og nerder og at ingen seriøse skoler
8120 kunne ta dette i bruk. Heldigvis er kunnskapen større nå og
8121 skikkelige
"IT-folk
" søker alltid å utvide sin kunnskap.
8123 <p
><strong

</strong

8125 <p
>Ja det er mange fordeler. Uavhengighet, stabilitet, åpenhet, standarder

8127 elevene skal jobbe.
</p

8129 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong

8131 <p
>Det største hinderet er det vi opplever på andre områder rundt
8132 fri programvare, nemlig kunnskap. For mange er det trygt å velge det vi
8133 alltid har valgt. Fordi leverandørene rundt oss sitter på den kunnskapen og
8134 de vi støtter oss på har den samme. Hvis vi klarer å riste løs litt og
8135 glemme gamle kriger mellom operativsystemer og leverandører, men sette ned
8136 hva som er viktig og velge ut fra det, så hadde man kanskje kommet ut med
8137 litt andre resultat. Jeg tror IT-folk er konservative og velger tradisjonelt
8138 og det er synd.

8140 <p

8142 <p
>Jeg bruker Ubuntu, Android, Jolicloud, Open Office, Zimbra, Picasa
8143 og Firefox samt en bråte med tjenester som er webbasert. Det eneste
8144 som er betalingslisens for er OSX. Ser at jeg jobber mer og mer i
8145 skyen og setter pris på alt jeg slipper egen klient til. Derfor er
8146 jeg veldig sjarmert av små kjappe operativsystemer som krever minimalt
8147 av maskinvaren.

><strong
>Hvilken strategi tror du er den rette å bruke for å få
8150 skoler til å ta i bruk fri programvare?

8152 <p
>Tror en blanding av krav og informasjon er veien å gå. Krav om
8153 sikkerhet, oppetid og åpne standarder. Informasjon om muligheter og
8154 alternativer. Her har leverandører, IT-avdelinger og pedagoger en vei
8155 å gå sammen. Det er til slutt LÆRING det dreier seg om, og da må man
8156 få mest mulig læring for pengene man har.

8173 <p
>Sturle Sunde, ansvarleg for skulenettet i Flora kommune. Eg driv,
8174 vidareutviklar og er andrelinje brukarstøtte for datanettet ved
8175 skulane i Flora kommune.
10 skular og meir enn
700 maskiner med
8176 Linux, medrekna tynnklientar. Tidlegare jobba eg i mange år med
8177 unix-drift ved Universitetets senter for informasjonsteknologi ved
8178 Universitetet i Oslo.

8180 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p

8182 <p
>Det er vanskeleg å svare konkret på. Eg har drive med Unix og Linux i
8183 alle år, og Skulelinux er eit godt kjent prosjekt i miljøet. Det var
8184 først i
2008, då eg tok til i min noverande jobb, at eg fekk bruk for
8185 Skulelinux for alvor.
</p
>
8187 <p
>Jobben min skulle vere drift av eit nytt skulenett i Flora kommune,
8188 levert av eit firma eg ikkje vil reklamere for. Systemet skulle vere
8189 ferdig levert i september året før. Dette viste seg å ta mykje lenger
8190 tid, og i haustferien
2008 hadde dei endå ikkje klart å få opp ei
8191 fungerande løysing. Situasjonen var prekær for den største skulen i
8192 kommunen med meir enn
500 elevar på ungdomssteget. Skulen hadde brukt
8193 Skulelinux før, og var tilfredse med det. No hadde dei vore utan
8194 fungerande datasystem i nesten eit år. Difor fekk eg opp ein ny tenar
8195 utanfor prosjektet og installerte Skulelinux på den. Etter litt
8196 justering av konfigurasjonen med god hjelp av #skolelinux på IRC, var
8197 den nye tenaren oppe og gjekk med både tynne og halv-tjukke klientar.
8198 Autentisering gjekk mot det nye systemet, slik at elevar og lærarar
8199 framleis har same brukarnamn og passord over alt. Dette berre
8200 fungerte, og vi bestemte oss for å erstatte delar av løysinga vi
8201 skulle få levert med Skulelinux.
</p
>
8203 <p
>Det høyrer med til historia at det nye systemet eg skulle drive frå
8204 januar
2008 endå ikkje er ferdig levert. Dei jobbar med saka, seier
8205 dei, og har von om å fullføre leveransen i løpet av
2011.
</p

8207 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
8209 <p
>Det er veldig mange. Eg skal ta nokre få.
</p
>
8211 <p
>Den viktigaste fordelen er at det igrunn berre er ei maskin å passe
8212 på, og det er tenaren. Med andre løysingar har ein gjerne programvare
8213 og anna som skal vedlikehaldast på kvar enkelt maskin. Med Skulelinux
8214 kan alle feil rettast og alle program oppgraderast på alle maskiner
8215 samstundes ved å gjere endringa som må til på tenaren. Eg kan sitje
8216 på kontoret og passe på alle tenarane i kommunen derifrå.
</p
>
8220 <li
>Tynne klientar gjer det mogleg å bruke eldre utstyr lenge, so lenge
8221 tenaren er sterk nok. Ein liten tenar med eit par halv-moderne CPUar
8222 og
2 GiB RAM held lenge for eit typisk klasserom med
30 tynnklientar,
8223 og det er lett å utvide med fleire.
8225 <li
>Halvtjukke klientar gjer det mogleg å utnytte kapasiteten i litt
8226 nyare maskiner betre, og avlaste tenaren. Ingenting vert installert
8227 lokalt på desse heller, og harddisken kan gjerne koblast frå. Gode
8228 halvtjukke klientar kan kjøpast brukt for under
1000-lappen, og det er
8229 heile kostnaden. Ingen lisensar eller anna på toppen, og det er ikkje
8230 krav til kraftigare tenar heller.
8232 <li
>Det er Linux. Vi har ikkje noko kluss med drivarar, dei berre er
8233 der. Heller ikkje med virus, dei finst i realiteten ikkje. Eller med
8234 elevar som klussar med installert programvare, for dei klarar ikkje å
8235 øydeleggje for nokon andre enn seg sjølve.
8239 <p
>Skulelinux er lagt opp til å vere veldig lett å installere rett ut
8240 av boksen på ein heil skule av ein interessert lærar. Det er ofte ei
8241 god løysing for skulen. Å ha nokon til stades som kjenner systemet og
8242 kan forklare enkle ting eller løyse problem der og då, er uvurderleg
8243 viktig for ein stressa lærar fem minutt før det ringer inn.
</p
>
8245 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
8247 <p
>All den ferdige konfigurasjonen gjer det tungvint å tilpasse
8248 Skulelinux til eit system som skal fungere saman med mange andre
8249 installasjonar i eit felles datanett for skulane i ein kommune. Det
8250 heile er prekonfigurert for ein skule, og utviding til mange skular
8251 med eigne tenarar er ikkje berre enkelt.
</p
>
8253 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
8255 <p
>Eg brukar mest alle små hjelpeprogram som føl med operativsystemet,
8256 samt scriptspråket perl. Elles er Firefox/Iceweasel, Gnome-terminal
8257 og ssh i kontinuerleg bruk. Av Linux-distribusjonar brukar eg både
8258 Debian, Ubuntu, SuSE og RedHat dagleg. Eg prøvar å finne det verktyet
8259 som passar best til kvar del av jobben.
</p
>
8261 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
8262 skoler til å ta i bruk fri programvare?
</strong
></p
>
8264 <p
>Det er to målgrupper ein må sikte mot. Det eine er alle skulane som
8265 manglar eller har eit lite tilfredsstillande opplegg i dag, og ikkje
8266 har råd til å kjøpe noko nytt og blankpussa opplegg. Der er det om å
8267 gjere å gjere det enkelt for skulane å finne Skulelinux, og gjere det
8268 enkelt for dei å få hjelp til installasjon på skulen. Gjerne med
8269 lokale kontaktpersonar. Her er det dugnadsinnsats som må til, for
8270 desse skulane har ikkje råd til å betale for dette.
</p
>
8272 <p
>Den andre og kanskje viktigare målgruppa er dei meir eller mindre
8273 profesjonelle kundane. Alle store offentlege innkjøp, inkludert
8274 innkjøp av nytt datasystem for skular, må ut på offentleg anbod.
8275 Offentlege anbod er mykje meir lukka enn dei gjev inntrykk av, og både
8276 regelboka og boka med triks for å sminke tilbodet er tjukk. Det er
8277 vanskeleg å komme inn utan eit solid salsapparat i ryggen. Kanskje
8278 Skulelinux skulle prøve aktivt å få seg eit partnarskap med eit av dei
8279 store som gjerne vil sterkare inn på den offentlege IT-marknaden?
8280 Nokon som kjenner triksa og har krefter til å ta opp kampen mot både
8281 dårlege anbod og Rudolf Blostrupmoen IT AS. Leveranse til skulane i
8282 ein kommune er ein god måte å få ein fot inn døra som leverandør til
8283 ein lukrativ kommunemarknad som kjøper alle tenester. Ta kontakt med
8284 nokon som er passeleg store og ikkje er Microsoft-partnar, og fortell:
8285 «Vi har eit ferdig produkt som du kan selje. Nei vi skal ikkje ha for
8286 det. Du kan gjerne gjere kva du vil med det, berre vi får lov til å
8287 hjelpe deg. Målgruppa er alle kommunar, og det er noko dei vil ha.
8288 Det er eit godt produkt, brukt av mange og godt likt.»

8308 40% lærer og
60% IKT med Windows XP, Win2003 server og et regionalt
8309 IKT-regime som legger premissene og begrensingene for hva vi kan gjøre

8314 <p
>Jeg leste en artikkel om en dugnadsinstallasjon av Skolelinux på en
8315 skole på Jæren et sted. Tanken om dugnad og frihet appellerte til
8316 meg. Da vi skulle bygge ny skole var det en del vi måtte spare på,
8317 fordi vi beveget oss mot en kostnadssprekk. Kabling og investering i
8318 PC-er var en av tingene vi sparte på. Derfor kjøpe vi
72 pc-er for
390
8319 pr stk. En filtjener og en applikasjonsserver.

8321 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong

8323 <p
>Fordelen er at så mye er satt opp fra starten. I tillegg er det
8324 tydelig at pakka er laga for skoleverket. Brukerne har egne
8325 skrivebord, tilgang på mange gode verktøyprogrammer. Vi slipper å
8326 tenke på virus. Brukerne har ikke mulighet til å ødelegge
8327 klientoppsett, men har gode muligheter til å endre eget oppsett. Dette
8328 tror jeg er inspirerende og kjekt for mange brukere. Mappestrukturen
8329 er ferdig og det er
"enkelt
" å designe lokale mappestrukturer via
8330 skeleton. Noen av oss i skoleverket mener skolen skal være en
8331 "mot-kultur
". Da er Skolelinux et av valgene man kan ta. Et annet er å
8332 spise på indisk restaurant i stedet for Mc Donald
's når vi er på bytur
8333 osv.. Ordene deling, frihet, dugnad osv er positive ord i
8334 skoleverket. Det er viktig at elevene blir bevisst dette.

8336 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p

8338 <p
>Kompabiliteten er selvsagt et problem, selv om det er mindre nå enn
8339 før. For IKT-personer på skolene som skal drifte dette er det
8340 problematisk med kommandoer i terminalen. I tillegg er det alt for
8341 mange programmer i Skolelinux som ikke blir brukt. Jeg tror
8342 Skolelinux er tjent med å tone ned begrepet pedagogisk programvare.
8343 Slik jeg ser det finnes ikke denne kategorien programmer lengre slik
8344 de gjorde før, som frittsående programmer som installeres på en
8345 datamaskin eller på serveren. Det finnes en del spesialpedagogiske
8346 programmer, som Textpilot, LingDys, LingRight, AskiRaski, Ny i Norge
8347 osv. Men dette er programmer for enkelt-elever eller små grupper av
8348 elever. Det som bør være fokus er at alle undervisningsressurser som
8349 lages for nettet skal være nettleseruavhengig.

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

8353 <p
>OpenOffice bruker jeg til vanlig kontorarbeide. VLC bruker jeg som
8354 videoavspiller og av og til streaming av film. Gimp bruker jeg i
8355 undervisningen til bildemanipulering. Firefox og Chrome er mine
8356 favoritt-nettlesere. Firefox har lenge vært førstevalget mitt, nå
8357 bruker jeg mest Chrome. Opplever den som raskere og smidigere enn
8358 Firefox. Ubuntu bruker jeg som dualboot på jobb-maskinen min i
8359 tillegg til at alle PCer hjemme har en eller annen Ubuntu-distribusjon
8360 installert. Jeg bruker Clonezilla på Ubuntu
10.04 til kloning av
8361 datamaskiner på jobb. Det er selvsagt en haug andre frie programmer
8362 jeg bruker men jeg bruker dem ikke daglig. Jeg kan ramse opp:
8363 recordmydesktop, cinelerra, acidrip, soundjuicer, audacity, NX
8364 (no-machine), Kino, Rythmbox...

><strong
>Hvilken strategi tror du er den rette å bruke for å få
8367 skoler til å ta i bruk fri programvare?
</strong
></p
>
8369 <p
>Jeg tror oppsøkende virksomhet er den rette strategien.
8370 Ressurspersoner gjør avtaler med rådmenn, skolesjefer, rektorer. Det
8371 er slik konkurrentene gjør det. Fokuset i slike samtaler bør være
8372 kost-nytte. Dersom personer med økonomisk ansvar ser at de kan få
8373 like godt tilbud til mindre utgifter, tror jeg det er mulighet til å
8374 få innpass. Dersom de også kan få konkrete tilbud på drift i slike
8375 samtaler, vil de kanskje bli litt mer interesserte i hvor mye penger
8376 som faktisk går til IKT i skolene. Det er også viktig at vi ikke
8377 firer for mye på krav til datamaskiner. Det er flott at Skolelinux
8378 går på
"utrangert
" utstyr, men dette bør bare presenteres som et
8379 alternativ. Skolelinux-installasjoner med utrangert utstyr er ikke å
8380 foretrekke dersom man kan unngå det. Det skaper ikke entusiasme hos
8381 brukerne (elever og lærere) når de bruker gamle datamaskiner som går
8382 tregt. Det er kjempefint med skoler som har kommet seg frem til
8383 Skolelinux og fri programvare av seg selv, men de lever på nåde.
8384 Slike valg må fundamenteres hos skoleeier.

8415 <p
>Gjennom en eller annen nettavis i
2001 der var det skrevet om
8416 Skolelinux. Artikkelen ga meg lyst til å prøve ut systemet.
</p

8418 <p
>Det startet i
2002 ved at jeg installerte en av de første utgavene
8419 av Skolelinux på en standard pc på Solneset skole i Tromsø. Denne var
8420 oppe fram til desember
2003 da jeg sluttet på den skolen og begynte i
8421 ny jobb i Narvik kommune.

8423 <p
> I Narvik kommune var det i
2004 kun
2 servere på da totalt
15
8424 skoler. Disse var Windows NT baserte. På disse to skolene var det lite
8425 med maskiner. Jobben med å få Narvik Kommune opp på akseptabelt nivå
8426 virket å være formidabel. Men med hjelp av gode kollegaer og leder
8427 skrev jeg en IKT plan for Narvik kommune som ble vedtatt av politikere
8428 i august
2004. I denne planen ble det bestemt at Narvik kommune skulle
8429 bruke Skolelinux. Her ble det også satt av midler til kabling av god
8430 infrastruktur på alle skoler samt innkjøp av nye datamaskiner. Så i
8431 dag har vi
17 servere hvorav
13 er på Skolelinux, med ca
1500 klienter

8523 en arkitektur med sentral-drift som gir mange driftfordeler. I

8567 <p
>Kommunen min har to omtrent jevnstore tettsteder, og en
8568 ungdomsskole i hvert av tettstedene. Den minste av disse har ca
300
8569 elever og til denne sogner det
3 barneskoler. Den største har ca
350
8570 elever og til denne sogner det
4 barneskoler.
</p
>
8574 <li
>Kommunen har i veldig lang tid forsømt IKT i skolen, og det har
8575 bare blitt gitt smuler i ny og ne. Det er kun den største av
8576 ungdomsskolene som har hatt en skikkelig datapark, og dette takket
8577 være en naturfaglærer som ble lei av å vente på kommunen. Det gjorde
8578 at vi bestemte oss for å ta ting i egne hender, og da vha
8579 skolelinux. En testinstallasjon med
10 gamle PCer ble gjort, og vi så
8580 raskt at dette var veldig lovende. Neste etappe var å gi alle lærere
8581 egen PC på arbeidsplassene sine (
2004), og så sette opp
16 PCer på to
8582 datarom. Vi har kun basert oss på å kjøpe inn brukte maskiner, og
8583 aldri dyrere enn
1000 kr pr klient. For to år siden så hadde vi
8584 klienter i alle klasserom, og totalt hadde vi da rundt
250 stk. Rundt
8585 40 klienter brukes av lærerne og kjører på en egen server. Elvene har
8586 resten, og kjører også en egen server. Servere har vi også kjøpt
8587 brukt,
2 år gamle servere koster
6-
7000 kroner.
</li
>
8589 <li
>Skolen vår er et relativt gammelt bygg, men en meget dyktig
8590 vaktmester har sammen med IKT-ansvarlig/Naturfaglærer lagt kabler til alle
8591 rom. Gradvis har vi byttet ut billige svitsjer med mer solide saker
8592 som er mulig å fjernstyre.
</li
>
8594 <li
>Vi har i all hovedsak greid å få dette til over eget budsjett, men
8595 vi har også passet på å få penger når de andre skolene har fått
8596 bærbare PCer til lærere osv.
</li
>
8598 <li
>Vår IKT-ansvarlig har gjort (og gjør) en fenomenal jobb, og vi har
8599 en maskinpark som de andre av kommunens skoler bare kan drømme
8604 <p
>Så skjer det som ofte skjer. Det kommer en eller annen
8605 selger/blåruss og skal fikse ALT. I vårt tilfelle betyr dette også
8606 sentralisering av drift. Den ny-ansatte på kommunens IT-avdelingen
8607 skal også ha jobb, og ser for seg å ta over skoledriften. Kommunen
8608 kjøper inn eksterne driftstjenester, og nekter i samme slengen å ta
8609 hensyn til skolen vår. Dette til tross for at vi alene har like mange
8610 datamaskiner som de andre til sammen.
</p
>
8614 <li
>Det blir krevd at vi skal innlemmes i de kommunale systemet, og
8615 det er VI som får ansvar for at dette kommer på plass. Og det er her
8616 de horrible tingene begynner å skje.
</li
>
8618 <li
>Det settes opp en lukket Exchange server som gjør av vi ikke kan
8619 hente epost for våre ansatte. Og det kreves at vi finner løsning på
8622 <li
>Det velges sak arkivsystem som vi pålegges å bruke, noe som gjør
8623 at vi må bruke en terminalløsning mot kommunal server. Ikke i seg selv
8624 et problem i følge IKT-ansvarlig hos oss. Men kommunens IT-avd nektet
8625 faktisk å åpne de porter OSV som vi måtte bruke.
</li
>
8627 <li
>Vi blir pålagt å flytte på innsiden av det kommunale
8628 nettverket. Dette gjorde at vi mistet hjemmekontor for lærere og
8629 elever. Å få åpnet porter i kommunal brannmur var ikke
8630 aktuelt. Mulighet for fjerndrift ble også vekk i samme slengen.
</li
>
8632 <li
>Vår LMS Moodle er ikke mulig å nå for elevene og lærerne.
8636 <p
>Den andre ungdomsskolen i kommunen begynner så å kreve at de skal
8637 få bedre datatetthet, og komme opp på et nivå som ligner det vi
8638 har. De ser at vi kan avholde eksamen hvor alle
10. klassingene får
8639 sitte ved hver sin PC. Og de har fått tilbakemelding (klager) fra VGS
8640 om manglende datakompetanse på elevene som kommer fra dem. Dette fører
8641 videre til at kommunen endelig innser at de må ta grep.
</p
>
8643 <p
>Grepet betyr sentralisering, og farvel til vår plattform får vi
8644 høre. Det blir gjort en rekke bestemmelser og vedtak som vi ikke får
8645 være en del av. Det blir helt klart at vi må redusere antall maskiner,
8646 og det skal satses på bærbare maskiner. Siden vi ikke har fått tatt
8647 del i prosessene som angår oss, så bruker vi fagforening. Vi har ikke
8648 blitt hørt i forbindelse med endringer som er betydelig for vår
8649 hverdag, og greier å stoppe omlegging. I tillegg så har vi et politisk
8650 vedtak i kommunen på at vi skal kjøre Linux på elevnett, og dette
8651 vedtaket kan ikke administrasjonen i kommunene helt uten videre
8652 tilsidesette.
</p
>
8654 <p
>I sum har dette gjort at vi har fått jobbe videre i fred. Og en del
8655 runder i kommunens kontrollutvalg har gjort det tydelig at vi har blitt
8656 systematisk motarbeidet.
</p
>
8658 <p
>I dag har de andre skolene fått sine bærbare maskiner til elever og
8659 lærere, men etter
2 år med innkjøring er det fremdeles problemer

8665 det er for mye arbeid å renske disse for innhold slik at juks ikke er

8674 å komme seg på nett. Og lagring på felles server er bare å glemme i

8679 <p
>Vi har slitt mye, kranglet og sloss. Ikke med tekniske problemer,
8680 men med omgivelsene rundt som vil oss til livs. Men det har vært verdt
8681 hver dråpe med svette, og timer med irritasjon. Men vi har begynt å få
8682 rutine her nå.

8725 leserinnlegg myntet på aviser. Disse er ikke sendt til aviser, men
8726 brukt internt i forbindelse med møter med kommune. Vår IKT-ansvarlig
8727 har også truet med å si opp jobben sin hvis det ikke ble tatt hensyn i
8728 større grad enn hva som har vært tilfelle. VI kan også dokumentere
8729 flere brudd på anbudsregler, og vi kjenner til at relativt store
8730 IT-leverandører som ikke har fått tatt del i disse anbudene, rett og
8731 slett ikke tør melde fra av redsel for å få et dårlig rykte.

8737 <p
>Jeg glemte å nevne at vi nå nesten ikke bruker tid på å drifte
8738 systemet vårt, noe som gjør at det aller meste av tid blir brukt til å
8739 støtte lærerne og elevene. F.eks så bruker vår IKT-ansvarlig den
8740 første timen på jobb,
0730-
0830 kun til å gå ute på arbeidsplassene
8741 til læreren. Dette for å kunne svare på små og store problem, gi tips
8742 og råd, eller bare for å plukke opp hva som er behovet ute i
8743 undervisningsarealene. Det er dessverre ikke slik at alle lærerne har
8744 nok digital kompetanse til å kunne formulere alle spørsmålene de har,
8745 men ved å kunne få vise eller lufte tanker med IKT-ansvarlig så er det
8746 utrolig hva som kommer fram.
</p
>
8750 <li
>Jeg ser at mange bruker økonomi som argument i forhold til å bruke
8751 SkoleLinux, og jeg skal ikke legge skjul på at det var dette som i
8752 utgangspunktet var årsaken til vårt valg. Men diskusjonene og kampen
8753 med kommunens IT-avdeling har gjort at vi har fått et noe annet
8754 fokus. Fordelene med drift og stabilitet, gjør at vi ville ha valgt
8755 samme løsning selv om den var dyrere. At vi slipper langt billigere
8756 unna, som følge av
0,- lisenskostnader og lave maskinvarekostnader, er
8757 bare en bonus.
</li
>
8759 <li
>Etter å ha kranglet oss til å få skikkelig oversikt over hva de
8760 andre skolene i kommunen bruker på IT, så har vi fått gehør for å få
8761 samme midler til innkjøp. Dette har gjort at vi nå kan kjøpe inn
8762 utstyr som de andre skolene bare kan se langt etter. Vi har nettopp
8763 kjøpt inn
3 videokamera i semiproff-klassen for å kunne lage film,
8764 samt sende live fra skoleteater/konserter. Vi har kjøpt inn digitale
8765 kompaktkamera til alle klassene. Vi har et team av lærere som skal i
8766 gang med å teste ut tablets på svake elever. Håpet et at teknologien
8767 kan være med på å gi noen av elevene litt mer motivasjon. Vi har kjøpt
8768 inn et halvt klassesett med pulsklokker, noe som har vist seg å være
8769 overraskende inspirerende for en del av elevene. Vi har også oss på
8770 fag på en høyskole litt lengre sør for oss, slik at
3 av oss nå skal
8771 ta faget
"Linux tjenestedrift
". Som inspektør og en del av skolens
8772 administrasjon er det veldig praktisk å kunne trå til hvis det
8773 kniper. Men IKT-ansvarlig har vært UTROLIG flink til å lage rene
8774 smørbrødlister for hvordan de mest vanlige driftsproblem løses, så det
8775 er lett for flere av oss å ta del i den daglige driften. Vi har svært
8776 stor nytte av lærling (som også hjelper to av naboskolene), men det er
8777 nesten blitt slik at det er om å gjøre å komme til først for å få løse
8778 problem. Det å få fingrene på problem og utfordringer er den aller
8779 beste læremester.
</li
>
8783 <p
>Når vi nå tar til med planlegging av ny skole, så vil det være med
8784 tanke på at det skal være mulig med datautstyr på alle plasser. Vi
8785 kommer i all hovedsak til å legge kabel til alle tenkelige og
8786 utenkelige plasser. WiFi koster tilnærmet NULL å sette opp i
8789 <p
>Vi har ikke vært noe flink til å bidra til SkoleLinux-prosjektet,
8790 vi har rett og slett vært for opptatt med vår egen kamp. Vi har hentet
8791 mye inspirasjon fra diskusjoner som har gått i det miljøet, og vi
8792 håper at vi nå framover kan få tid til å bidra. Vi er i ferd med å
8793 bytte ut en av serverne våre, og da vil denne trolig bli satt opp som
8794 testserver for neste versjon av Skolelinux. På den måten vil vi i alle
8795 fall kunne gi tilbakemeldinger og rapportere feil. I tillegg så vil
8796 det kanskje gi oss noen nye utfordringer, for som lærlingen vår sier:
8797 "Skolelinux er noe herk, det skjer jo ikke noe galt og hvordan skal
8798 jeg da lære?

8827 something fail, I make a note about this in the test matrix and move

>In the latest issue of Linux Journal, the readers choices were
8930 presented, and the winner among the multimedia player were VLC.
8931 Personally, I like VLC, and it is my player of choice when I first try
8932 to play a video file or stream. Only if VLC fail will I drag out
8933 gmplayer to see if it can do better. The reason is mostly the failure
8934 model and trust. When VLC fail, it normally pop up a error message
8935 reporting the problem. When mplayer fail, it normally segfault or
8936 just hangs. The latter failure mode drain my trust in the program.

8941 plugin to play web videos seamlessly, and the VLC browser plugin is
8942 not very good. For example, it lack in-line control buttons, so there
8943 is no way for the user to pause the video. Also, when I
8944 <a href=
"http://wiki.debian.org/DebianEdu/BrowserMultimedia
">last
8945 tested the browser plugins
</a
> available in Debian, the VLC plugin
8946 failed on several video pages where mplayer based plugins worked. If
8947 the browser plugin for VLC was as good as the gecko-mediaplayer
8948 package (which uses mplayer), we would switch.
</P
>
8950 <p
>While VLC is a good player, its user interface is slightly
8951 annoying. The most annoying feature is its inconsistent use of
8952 keyboard shortcuts. When the player is in full screen mode, its
8953 shortcuts are different from when it is playing the video in a window.
8954 For example, space only work as pause when in full screen mode. I
8955 wish it had consisten shortcuts and that space also would work when in
8956 window mode. Another nice shortcut in gmplayer is [enter] to restart
8957 the current video. It is very nice when playing short videos from the
8958 web and want to restart it when new people arrive to have a look at
8959 what is going on.

9415 are virtual machines. And they have been Xen machines running on a
9416 fairly old IBM eserver xseries
345 machine, and we wanted to migrate
9417 them to KVM on a newer Dell PowerEdge
2950 host machine. This was a
9418 bit harder that it could have been, because we set up the Xen virtual
9419 machines to get the virtual partitions from LVM, which as far as I
9420 know is not supported by KVM. So to migrate, we had to convert
9421 several LVM logical volumes to partitions on a virtual disk file.

9427 image, parted to partition it, losetup and kpartx to present the disk
9428 image partions as devices, and dd to copy the data. I NFS mounted the
9429 new servers storage area on the old server to do the migration.

9729 finally got around to do a test installation of Debian/Squeeze with
9730 kfreebsd. Installation went fairly smooth, thought I noticed some
9731 visual glitches in the cdebconf dialogs (black cursor left on the
9732 screen at random locations). Have not gotten very far with the
9733 testing. Noticed cfdisk did not work, but fdisk did so it was not a
9734 fatal problem. Have to spend some more time on it to see if it is
9735 useful as a file server for NUUG. Will try to find time to set up a

>Prioritising packages for the Debian Edu /

"http://www.skolelinux.org/
">Skolelinux
</a
> DVD, which is
9747 supposed provide a school with all the services and user applications
9748 needed on the pupils computer network has always been hard. Even
9749 schools without Internet connections should be able to get Debian Edu
9750 working using this DVD.
</p
>
9752 <p
>The job became a lot harder when apt and aptitude started
9753 installing recommended packages by default. We want the same set of
9754 packages to be installed when using the DVD and the netinst CD, and
9755 that means all recommended packages need to be on the DVD. I created
9756 a patch for debian-cd in
<a href=
"http://bugs.debian.org/
601203">BTS
9757 report #
601203</a
> to do this, and since this change was applied to
9758 the Debian Edu DVD build, we have been seriously short on space.
</p
>
9760 <p
>A few days ago we decided to drop blender, wxmaxima and kicad from
9761 the default installation to save space on the DVD, believing that
9762 those needing these applications are few and can get them from the
9763 Debian archive.
</p
>
9765 <p
>Yesterday, I had a look what source packages to see which packages
9766 were using most space. A few large packages are well know;
9767 openoffice.org, openclipart and fluid-soundfont. But I also
9768 discovered that lilypond used
106 MiB and fglrx-driver used
53 MiB.
9769 The lilypond package is pulled in as a dependency for rosegarden, and
9770 when looking a bit closer I discovered that
99 MiB of the
106 MiB were
9771 the documentation package, which is recommended by the binary package.
9772 I decided to drop this documentation package from our DVD, as most of
9773 our users will use the GUI front-ends and do not need the lilypond
9774 documentation. Similarly, I dropped the non-free fglrx-driver package
9775 which might be installed by d-i when its hardware is detected, as the
9776 free X driver should work.
</p
>
9778 <p
>With this change, we finally got space for the LXDE and Gnome
9779 desktop packages as well as the language specific packages making the
9780 DVD more useful again.

9791 <p
>My
<a href=

">gnash pledge
</a

9792 raise money for the project is going well. The lower limit of
10
9793 signers was reached in
24 hours, and so far
13 people have signed it.
9794 More signers and more funding is most welcome, and I am really curious
9795 how far we can get before the time limit of December
24 is reached.
9798 <p
>On the #gnash IRC channel on irc.freenode.net, I was just tipped
9799 about what appear to be a great code coverage tool capable of
9800 generating code coverage stats without any changes to the source code.

&gt;
</tt
>.
9804 It is missing in Debian, but the git source built just fine in Squeeze
9805 after I installed libelf-dev, libdwarf-dev, pkg-config and
9806 libglib2.0-dev. Failed to build in Lenny, but suspect that is
9807 solvable. I hope kcov make it into Debian soon.

9814 release. Give it a try if you need a complete linux solution for your
9815 school, including central infrastructure server, workstations, thin
9816 client servers and diskless workstations. A nice touch added
9817 yesterday is RDP support on the thin client servers, for windows
9818 clients to get a Linux desktop on request.

9829 second most popular used package that is missing in Debian. The sixth
9830 most popular is flashplayer-mozilla. This is a clear indication that

10 percent of the

9839 schools experienced with
<a href=
"http://www.skolelinux.org/
">Debian
9840 Edu/Skolelinux
</a
> was the lack of working Flash. A lot of educational
9841 web sites require Flash to work, and lacking working Flash support in
9842 the web browser and the problems with installing it was perceived as a
9843 good reason to stay with Windows.
</p
>
9845 <p
>I once saw a funny and sad comment in a web forum, where Linux was
9846 said to be the retarded cousin that did not really understand
9847 everything you told him but could work fairly well. This was a
9848 comment regarding the problems Linux have with proprietary formats and
9849 non-standard web pages, and is sad because it exposes a fairly common
9850 understanding of whose fault it is if web pages that only work in for
9851 example Internet Explorer
6 fail to work on Firefox, and funny because
9852 it explain very well how annoying it is for users when Linux
9853 distributions do not work with the documents they receive or the web
9854 pages they want to visit.
</p
>
9856 <p
>This is part of the reason why I believe it is important for Debian
9857 and Debian Edu to have a well working Flash implementation in the
9858 distribution, to get at least popular sites as Youtube and Google
9859 Video to working out of the box. For Squeeze, Debian have the chance
9860 to include the latest version of Gnash that will make this happen, as
9861 the new release
0.8.8 was published a few weeks ago and is resting in
9862 unstable. The new version work with more sites that version
0.8.7.
9863 The Gnash maintainers have asked for a freeze exception, but the
9864 release team have not had time to reply to it yet. I hope they agree
9865 with me that Flash is important for the Debian desktop users, and thus
9866 accept the new package into Squeeze.

10040 <description><p
>As reported earlier, the last few days I have looked at how Debian
10041 Edu clients are configured, and tried to get rid of all hardcoded
10042 configuration settings on the clients. I believe the work to be
10043 mostly done, and the clients seem to work just fine with dynamically
10044 generated configuration.
</p
>
10046 <p
>What is the point, you might ask? The point is to allow a Debian
10047 Edu desktop to integrate into an existing network infrastructure
10048 without any manual configuration.
</p
>
10050 <p
>This is what happens when installing a Debian Edu client here at
10051 the University of Oslo using PXE. With the PXE installation, I am
10052 asked for language (Norwegian Bokmål), locality (Norway) and keyboard
10053 layout (no-latin1), Debian Edu profile (Roaming Workstation), if I
10054 accept to reformat the hard drive (yes), if I want to submit info to
10055 popcon.debian.org (no) and root password (secret). After answering
10056 these questions, the installer goes ahead and does its thing, and
10057 after around
50 minutes it is done. I press enter to finish the
10058 installation, and the machine reboots into KDE. When the machine is
10059 ready and kdm asks for login information, I enter my university
10060 username and password, am told by kdm that a local home directory has
10061 been created and that I must log in again, and finally log in with the
10062 same username and password to the KDE
4.4 desktop. At no point during
10063 this process did it ask for university specific settings, and all the
10064 required configuration was dynamically detected using information
10065 fetched via DHCP and DNS. The roaming workstation is now ready for
10068 <p
>How was this done, you might wonder? First of all, here is the
10069 list of things that need to be configured on the client to get it
10070 working properly out of the box:
</p
>
10073 <li
>IP address/netmask and DNS server.
</li
>
10074 <li
>Web proxy URL.
</li
>
10075 <li
>LDAP server for NSS directory information (user, group, etc).
</li
>
10076 <li
>Kerberos server for PAM password checking.
</li
>
10077 <li
>SMB mount point to access the network home directory. (*)
</li
>
10078 <li
>Central syslog server to send syslog messages to. (*)
</li
>
10079 <li
>Sitesummary collector URL to submit info to central server. (*)
</li
>
10082 <p
>(Hm, did I forget anything? Let me knew if I did.)
</p
>
10084 <p
>The points marked (*) are not required to be able to use the
10085 machine, but needed to provide central storage and allowing system
10086 administrators to track their machines. Since yesterday, everything
10087 but the sitesummary collector URL is dynamically discovered at boot
10088 and installation time in the svn version of Debian Edu.
</p
>
10090 <p
>The IP and DNS setup is fetched during boot using DHCP as usual.
10091 When a DHCP update arrives, the proxy setup is updated by looking for
10092 http://wpat/wpad.dat and using the content of this WPAD file to
10093 configure the http and ftp proxy in /etc/environment and
10094 /etc/apt/apt.conf. I decided to update the proxy setup using a DHCP
10095 hook to ensure that the client stops using the Debian Edu proxy when
10096 it is moved outside the Debian Edu network, and instead uses any local
10097 proxy present on the new network when it moves around.
</p
>
10099 <p
>The DNS names of the LDAP, Kerberos and syslog server and related
10100 configuration are generated using DNS information at boot. First the
10101 installer looks for a host named ldap in the current DNS domain. If
10102 not found, it looks for _ldap._tcp SRV records in DNS instead. If an
10103 LDAP server is found, its root DSE entry is requested and the
10104 attributes namingContexts and defaultNamingContext are used to
10105 determine which LDAP base to use for NSS. If there are several
10106 namingContexts attibutes and the defaultNamingContext is present, that
10107 LDAP subtree is used as the base. If defaultNamingContext is missing,
10108 the subtrees listed as namingContexts are searched in sequence for any
10109 object with class posixAccount or posixGroup, and the first one with
10110 such an object is used as the LDAP base. For Kerberos, a similar
10111 search is done by first looking for a host named kerberos, and then
10112 for the _kerberos._tcp SRV record. I
've been unable to find a way to
10113 look up the Kerberos realm, so for this the upper case string of the
10114 current DNS domain is used.
</p
>
10116 <p
>For the syslog server, the hosts syslog and loghost are searched
10117 for, and the _syslog._udp SRV record is consulted if no such host is
10118 found. This algorithm works for both Debian Edu and the University of
10119 Oslo. A similar strategy would work for locating the sitesummary
10120 server, but have not been implemented yet. I decided to fetch and
10121 save these settings during installation, to make sure moving to a
10122 different network does not change the set of users being allowed to
10123 log in nor the passwords required to log in. Usernames and passwords
10124 will be cached by sssd when the user logs in on the Debian Edu
10125 network, and will not change as the laptop move around. For a
10126 non-roaming machine, there is no caching, but given that it is
10127 supposed to stay in place it should not matter much. Perhaps we
10128 should switch those to use sssd too?
</p
>
10130 <p
>The user
's SMB mount point for the network home directory is
10131 located when the user logs in for the first time. The LDAP server is
10132 consulted to look for the user
's LDAP object and the sambaHomePath
10133 attribute is used if found. If it isn
't found, the home directory
10134 path fetched from NSS is used instead. Assuming the path is of the
10135 form /site/server/directory/username, the second part is looked up in
10136 DNS and used to generate a SMB URL of the form
10137 smb://server.domain/username. This algorithm works for both Debian
10138 edu and the University of Oslo. Perhaps there are better attributes
10139 to use or a better algorithm that works for more sites, but this will
10140 do for now. :)
</p
>
10142 <p
>This work should make it easier to integrate the Debian Edu clients
10143 into any LDAP/Kerberos infrastructure, and make the current setup even
10144 more flexible than before. I suspect it will also work for thin
10145 client servers, allowing one to easily set up LTSP and hook it into a
10146 existing network infrastructure, but I have not had time to test this
10149 <p
>If you want to help out with implementing these things for Debian
10150 Edu, please contact us on debian-edu@lists.debian.org.
</p
>
10152 <p
>Update
2010-
08-
09: Simon Farnsworth gave me a heads-up on how to
10153 detect Kerberos realm from DNS, by looking for _kerberos TXT entries
10154 before falling back to the upper case DNS domain name. Will have to
10155 implement it for Debian Edu. :)

>A few years ago, I was involved in a project planning to use
10165 Windows file servers as home directory servers for Debian
10166 Edu/Skolelinux machines. This was thought to be no problem, as the
10167 access would be through the SMB network file system protocol, and we
10168 knew other sites used SMB with unix and samba as the file server to
10169 mount home directories without any problems. But, after months of
10170 struggling, we had to conclude that our goal was impossible.
</p
>
10172 <p
>The reason is simply that while SMB can be used for home
10173 directories when the file server is Samba running on Unix, this only
10174 work because of Samba have some extensions and the fact that the
10175 underlying file system is a unix file system. When using a Windows
10176 file server, the underlying file system do not have POSIX semantics,
10177 and several programs will fail if the users home directory where they
10178 want to store their configuration lack POSIX semantics.
</p
>
10180 <p
>As part of this work, I wrote a small C program I want to share
10181 with you all, to replicate a few of the problematic applications (like
10182 OpenOffice.org and GCompris) and see if the file system was working as
10183 it should. If you find yourself in spooky file system land, it might

>A few days ago, I
10396 <a href=
"http://people.skolelinux.org/pere/blog/Debian_Edu_roaming_workstation___at_the_university_of_Oslo.html
">tried
10397 to install
</a
> a Roaming workation profile from Debian Edu/Squeeze
10398 while on the university network here at the University of Oslo, and
10399 noticed how much had to change to get it operational using the
10400 university infrastructure. It was fairly easy, but it occured to me
10401 that Debian Edu would improve a lot if I could get the client to
10402 connect without any changes at all, and thus let the client configure
10403 itself during installation and first boot to use the infrastructure
10404 around it. Now I am a huge step further along that road.
</p
>
10406 <p
>With our current squeeze-test packages, I can select the roaming
10407 workstation profile and get a working laptop connecting to the
10408 university LDAP server for user and group and our active directory
10409 servers for Kerberos authentication. All this without any
10410 configuration at all during installation. My users home directory got
10411 a bookmark in the KDE menu to mount it via SMB, with the correct URL.
10412 In short, openldap and sssd is correctly configured. In addition to
10413 this, the client look for http://wpad/wpad.dat to configure a web
10414 proxy, and when it fail to find it no proxy settings are stored in
10415 /etc/environment and /etc/apt/apt.conf. Iceweasel and KDE is
10416 configured to look for the same wpad configuration and also do not use
10417 a proxy when at the university network. If the machine is moved to a
10418 network with such wpad setup, it would automatically use it when DHCP
10419 gave it a IP address.
</p
>
10421 <p
>The LDAP server is located using DNS, by first looking for the DNS
10422 entry ldap.$domain. If this do not exist, it look for the
10423 _ldap._tcp.$domain SRV records and use the first one as the LDAP
10424 server. Next, it connects to the LDAP server and search all
10425 namingContexts entries for posixAccount or posixGroup objects, and
10426 pick the first one as the LDAP base. For Kerberos, a similar
10427 algorithm is used to locate the LDAP server, and the realm is the
10428 uppercase version of $domain.
</p
>
10430 <p
>So, what is not working, you might ask. SMB mounting my home
10431 directory do not work. No idea why, but suspected the incorrect
10432 Kerberos settings in /etc/krb5.conf and /etc/samba/smb.conf might be
10433 the cause. These are not properly configured during installation, and
10434 had to be hand-edited to get the correct Kerberos realm and server,
10435 but SMB mounting still do not work. :(
</p
>
10437 <p
>With this automatic configuration in place, I expect a Debian Edu
10438 roaming profile installation would be able to automatically detect and
10439 connect to any site using LDAP and Kerberos for NSS directory and PAM
10440 authentication. It should also work out of the box in a Active
10441 Directory environment providing posixAccount and posixGroup objects
10442 with UID and GID values.

>The new roaming workstation profile in Debian Edu/Squeeze is fairly
10455 similar to the laptop setup am I working on using Ubuntu for the
10456 University of Oslo, and just for the heck of it, I tested today how
10457 hard it would be to integrate that profile into the university
10458 infrastructure. In this case, it is the university LDAP server,
10459 Active Directory Kerberos server and SMB mounting from the Netapp file
10462 <p
>I was pleasantly surprised that the only three files needed to be
10463 changed (/etc/sssd/sssd.conf, /etc/ldap.conf and
10464 /etc/mklocaluser.d/
20-debian-edu-config) and one file had to be added
10465 (/usr/share/perl5/Debian/Edu_Local.pm), to get the client working.
10466 Most of the changes were to get the client to use the university LDAP
10467 for NSS and Kerberos server for PAM, but one was to change a hard
10468 coded DNS domain name in the mklocaluser hook from .intern to
10471 <p
>This testing was so encouraging, that I went ahead and adjusted the
10472 Debian Edu scripts and setup in subversion to centralise the roaming

>I just posted this announcement culminating several months of work
10493 with the next Debian Edu release. Not nearly done, but one major step
10494 completed.
</p

10497 <p
>This is the first test release based on Squeeze. The focus of this
10498 release is to test the user application selection. To have a look,
10499 install the standalone profile and let the developers know if the set
10500 of installed packages i.e. applications should be modified. If some
10501 user application is missing, or if there are some applications that no
10502 longer make sense to be included in Debian Edu, please let us know.
10503 Also, if a useful application is missing the translation for your
10504 language of choice, please let us know too.
</p
>
10506 <p
>In addition, feedback and help to polish the desktop (menus,
10507 artwork, starters, etc.) is appreciated. We would like to ship a nice
10508 and handy KDE4 desktop targeted for schools out of the box.

>The last few months me and the other Debian Edu developers have
10612 been working hard to get the Debian/Squeeze based version of Debian
10613 Edu/Skolelinux into shape. This future version will use Kerberos for
10614 authentication, and services are slowly migrated to single signon,
10615 getting rid of password questions one at the time.
</p
>
10617 <p
>It will also feature a roaming workstation profile with local home
10618 directory, for laptops that are only some times on the Skolelinux
10619 network, and for this profile a shortcut is created in Gnome and KDE
10620 to gain access to the users home directory on the file server. This
10621 shortcut uses SMB at the moment, and yesterday I had time to test if
10622 SMB mounting had started working in KDE after we added the cifs-utils
10623 package. I was pleasantly surprised how well it worked.
</p
>
10625 <p
>Thanks to the recent changes to our samba configuration to get it
10626 to use Kerberos for authentication, there were no question about user
10627 password when mounting the SMB volume. A simple click on the shortcut
10628 in the KDE menu, and a window with the home directory popped
10631 <p
>One step closer to a single signon solution out of the box in
10632 Debian Edu. We already had PAM, LDAP, IMAP and SMTP in place, and now
10633 also Samba. Next step is Cups and hopefully also NFS.
</p
>
10635 <p
>We had planned a alpha0 release of Debian Edu for today, but thanks
10636 to the autobuilder administrators for some architectures being slow to
10637 sign packages, we are still missing the fixed LTSP package we need for
10638 the release. It was uploaded three days ago with urgency=high, and if
10639 it had entered testing yesterday we would have been able to test it in
10640 time for a alpha0 release today. As the binaries for ia64 and powerpc
10641 still not uploaded to the Debian archive, we need to delay the alpha
10642 release another day.

>As a step to try to see if it possible to merge the DNS and DHCP
10663 LDAP objects, I have had a look at how the packages pdns-backend-ldap
10664 and dhcp3-server-ldap in Debian use the LDAP server. The two
10665 implementations are quite different in how they use LDAP.

10678 One
"strict
" mode where the forward and reverse DNS lookups are done
10679 using the same LDAP objects, and a
"tree
" mode where the forward and
10680 reverse entries are in two different subtrees in LDAP with a structure
10681 based on the DNS names, as in tjener.intern and
10682 2.2.0.10.in-addr.arpa.
</p
>
10684 <p
>In tree mode, the server is set up to use a LDAP subtree as its
10685 base, and uses a
"base
" scoped search for the DNS name by adding
10686 "dc=tjener,dc=intern,

10,dc=in-addr,dc=arpa,
" with a filter for
10689 "(associateddomain=
2.2.0.10.in-addr.arpa)
" for the reverse entry. For
10690 forward entries, it is looking for attributes named dnsttl, arecord,

10774 <p

10775 specify any objectclass names, and instead look for the attributes it

10783 <p
>In Debian Edu, we have created DNS objects using the object classes
10784 dcobject (for dc), dnsdomain or dnsdomain2 (structural, for the DNS
10785 attributes) and domainrelatedobject (for associatedDomain). The use
10786 of structural object classes make it impossible to combine these
10787 classes with the object classes used by DHCP.
</p

10789 <p
>There are other schemas that could be used too, for example the
10790 dnszone structural object class used by Gosa and bind-sdb for the DNS
10791 attributes combined with the domainrelatedobject object class, but in
10792 this case some unused attributes would have to be included as well
10793 (zonename and relativedomainname).
</p

10795 <p

10796 mode and not use any of the existing objectclasses (dnsdomain,
10797 dnsdomain2 and dnszone) when one want to combine the DNS information
10798 with DHCP information, and instead create a auxiliary object class
10799 defined something like this (using the attributes defined for
10800 dnsdomain and dnsdomain2 or dnszone):

10900 The object classes need to have fixed names, and the configuration

10904 it possible to group all host entries in a subtree next to the

10973 <description><p
>For a while now, I have wanted to find a way to change the DNS and
10974 DHCP services in Debian Edu to use the same LDAP objects for a given
10975 computer, to avoid the possibility of having a inconsistent state for
10976 a computer in LDAP (as in DHCP but no DNS entry or the other way
10977 around) and make it easier to add computers to LDAP.
</p
>
10979 <p
>I
've looked at how powerdns and dhcpd is using LDAP, and using this
10980 information finally found a solution that seem to work.
</p
>
10982 <p
>The old setup required three LDAP objects for a given computer.
10983 One forward DNS entry, one reverse DNS entry and one DHCP entry. If
10984 we switch powerdns to use its strict LDAP method (ldap-method=strict
10985 in pdns-debian-edu.conf), the forward and reverse DNS entries are
10986 merged into one while making it impossible to transfer the reverse map
10987 to a slave DNS server.
</p
>
10989 <p
>If we also replace the object class used to get the DNS related
10990 attributes to one allowing these attributes to be combined with the
10991 dhcphost object class, we can merge the DNS and DHCP entries into one.
10992 I
've written such object class in the dnsdomainaux.schema file (need
10993 proper OIDs, but that is a minor issue), and tested the setup. It
10994 seem to work.
</p
>
10996 <p
>With this test setup in place, we can get away with one LDAP object
10997 for both DNS and DHCP, and even the LTSP configuration I suggested in
10998 an earlier email. The combined LDAP object will look something like

11019 <p

11020 dhcphost in a different location, to allow us to put the objects
11021 outside the

11022 that. If I can
't figure out a way to do that, we can still get rid of
11023 the hosts subtree and move all its content into the DHCP Config tree
11024 (which probably should be renamed to be more related to the new

11026 might be a good place to put it.

>Vagrant mentioned on IRC today that ltsp_config now support
11039 sourcing files from /usr/share/ltsp/ltsp_config.d/ on the thin
11040 clients, and that this can be used to fetch configuration from LDAP if
11041 Debian Edu choose to store configuration there.
</p

11043 <p
>Armed with this information, I got inspired and wrote a test module
11044 to get configuration from LDAP. The idea is to look up the MAC
11045 address of the client in LDAP, and look for attributes on the form
11046 ltspconfigsetting=value, and use this to export SETTING=value to the
11047 LTSP clients.

11050 in a

11051 allowing us to store all information about a computer in one place.

11053 <p

11242 <description><p
>For a laptop, centralized user directories and password checking is
11243 a bit troubling. Laptops are typically used also when not connected
11244 to the network, and it is vital for a user to be able to log in or
11245 unlock the screen saver also when a central server is unavailable.
11246 This is possible by caching passwords and directory information (user
11247 and group attributes) locally, and the packages to do so are available
11248 in Debian. Here follow two recipes to set this up in Debian/Squeeze.
11249 It is also possible to set up in Debian/Lenny, but require more manual
11250 setup there because pam-auth-update is missing in Lenny.
</p
>
11252 <h2
>LDAP/Kerberos + nscd + libpam-ccreds + libpam-mklocaluser/pam_mkhomedir
</h2
>
11254 This is the traditional method with a twist. The password caching is
11255 provided by libpam-ccreds (version
10-
4 or later is needed on
11256 Squeeze), and the directory caching is done by nscd. The directory
11257 lookup and password checking is done using LDAP. If one want to use
11258 Kerberos for password checking the libpam-ldapd package can be
11259 replaced with libpam-krb5 or libpam-heimdal. If one is happy having a
11260 local home directory with the path listed in LDAP, one can use the
11261 pam_mkhomedir module from pam-modules to make this happen instead of
11262 using libpam-mklocaluser. A setup for pam-auth-update to enable
11263 pam_mkhomedir will have to be written until a fix for
11264 <a href=
"http://bugs.debian.org/
568577">bug #
568577</a
> is in the
11265 archive. Because I believe it is a bad idea to have local home
11266 directories using misleading paths like /site/server/partition/, I
11267 prefer to create a local user with the home directory in /home/. This
11268 is done using the libpam-mklocaluser package.

've been unable to get TLS

11281 LDAP authentication unsafe for Debian Edu (nslcd is not checking if it

11384 libpam-ccreds. It support LDAP and Kerberos, but not NIS. Version
11385 1.2 do not support netgroups, but it is said that it will support this

>The last few days I have been looking into the status of the LDAP
11449 directory in Debian Edu, and in the process I started to miss a GUI
11450 tool to browse the LDAP tree. The only one I was able to find in
11451 Debian/Squeeze and Lenny is
11452 <a href=
"http://luma.sourceforge.net/
">LUMA
</a
>, which has proved to
11453 be a great tool to get a overview of the current LDAP directory
11454 populated by default in Skolelinux. Thanks to it, I have been able to
11455 find empty and obsolete subtrees, misplaced objects and duplicate
11456 objects. It will be installed by default in Debian/Squeeze. If you
11457 are working with LDAP, give it a go. :)
</p
>
11459 <p
>I did notice one problem with it I have not had time to report to
11460 the BTS yet. There is no .desktop file in the package, so the tool do
11461 not show up in the Gnome and KDE menus, but only deep down in in the
11462 Debian submenu in KDE. I hope that can be fixed before Squeeze is
11463 released.
</p
>
11465 <p
>I have not yet been able to get it to modify the tree yet. I would
11466 like to move objects and remove subtrees directly in the GUI, but have
11467 not found a way to do that with LUMA yet. So in the mean time, I use
11468 <a href=
"http://www.lichteblau.com/ldapvi/

</a
> for that.

29: Ross Reedstrom tipped us about the
11474 <a href=
"http://packages.qa.debian.org/g/gq.html
">gq
</a
> package as a
11475 useful GUI alternative. It seem like a good tool, but is unmaintained
11476 in Debian and got a RC bug keeping it out of Squeeze. Unless that
11477 changes, it will not be an option for Debian Edu based on Squeeze.

11492 <p

11493 the dhcpHost object class auxiliary, to allow it to be combined with

11541 I am now testing dist-upgrade of Gnome and KDE in a chroot using both
11542 apt and aptitude, and found their differences interesting. This time
11543 I will only focus on their removal plans.
</p
>
11545 <p
>After installing a Gnome desktop and the laptop task, apt-get wants
11546 to remove
72 packages when dist-upgrading from Lenny to Squeeze. The
11547 surprising part is that it want to remove xorg and all
11548 xserver-xorg-video* drivers. Clearly not a good choice, but I am not
11549 sure why. When asking aptitude to do the same, it want to remove
129
11550 packages, but most of them are library packages I suspect are no
11551 longer needed. Both of them want to remove bluetooth packages, which
11552 I do not know. Perhaps these bluetooth packages are obsolete?
</p
>
11554 <p
>For KDE, apt-get want to remove
82 packages, among them kdebase
11555 which seem like a bad idea and xorg the same way as with Gnome. Asking
11556 aptitude for the same, it wants to remove
192 packages, none which are
11557 too surprising.
</p
>
11559 <p
>I guess the removal of xorg during upgrades should be investigated
11560 and avoided, and perhaps others as well. Here are the complete list
11561 of planned removals. The complete logs is available from the URL
11562 above. Note if you want to repeat these tests, that the upgrade test
11563 for kde+apt-get hung in the tasksel setup because of dpkg asking
11564 conffile questions. No idea why. I worked around it by using
11565 '<tt
>echo

<em
>pidofdpkg

11712 <description><p
>The last few days I have done some upgrade testing in Debian, to
11713 see if the upgrade from Lenny to Squeeze will go smoothly. A few bugs
11714 have been discovered and reported in the process
11715 (
<a href=
"http://bugs.debian.org/
585410">#
585410</a
> in nagios3-cgi,
11716 <a href=
"http://bugs.debian.org/
584879">#
584879</a
> already fixed in
11717 enscript and
<a href=
"http://bugs.debian.org/
584861">#
584861</a
> in
11718 kdebase-workspace-data), and to get a more regular testing going on, I
11719 am working on a script to automate the test.
</p
>
11721 <p
>The idea is to create a Lenny chroot and use tasksel to install a
11722 Gnome or KDE desktop installation inside the chroot before upgrading
11723 it. To ensure no services are started in the chroot, a policy-rc.d
11724 script is inserted. To make sure tasksel believe it is to install a
11725 desktop on a laptop, the tasksel tests are replaced in the chroot
11726 (only acceptable because this is a throw-away chroot).
</p
>
11728 <p
>A naive upgrade from Lenny to Squeeze using aptitude dist-upgrade
11729 currently always fail because udev refuses to upgrade with the kernel
11730 in Lenny, so to avoid that problem the file /etc/udev/kernel-upgrade
11731 is created. The bug report
11732 <a href=
"http://bugs.debian.org/
566000">#
566000</a
> make me suspect
11733 this problem do not trigger in a chroot, but I touch the file anyway
11734 to make sure the upgrade go well. Testing on virtual and real
11735 hardware have failed me because of udev so far, and creating this file
11736 do the trick in such settings anyway. This is a
11737 <a href=
"http://www.linuxquestions.org/questions/debian-
26/failed-dist-upgrade-due-to-udev-config_sysfs_deprecated-nonsense-
804130/
">known
11738 issue
</a
> and the current udev behaviour is intended by the udev
11739 maintainer because he lack the resources to rewrite udev to keep
11740 working with old kernels or something like that. I really wish the
11741 udev upstream would keep udev backwards compatible, to avoid such
11742 upgrade problem, but given that they fail to do so, I guess
11743 documenting the way out of this mess is the best option we got for
11744 Debian Squeeze.
</p
>

11747 script, which I call
<tt

11826 is able to migrate to dependency based boot sequencing and parallel

11828 packages failing to clean up their obsolete init.d script during
11829 upgrades, and no such problem seem to affect the Gnome desktop+laptop
11830 packages.

>Som systemarkitekten bak Skolelinux, kan jeg bare riste på hodet
11870 over påstanden om at Skolelinux krever desentraliserte tjenere.
11871 Skolelinux-arkitekturen er laget for sentralisert drift og plassering
11872 av tjenerne lokalt eller sentralt alt etter behov og nettkapasitet.
11873 Den er modellert på nettverks- og tjenerløsningen som brukes på
11874 Universitetet i Tromsø og Oslo, der jeg jobber med utvikling av
11875 driftstjenester. Dette er det heldigvis noen som har fått med seg, og
11876 jeg er glad for å kunne sitere fra en kommentar på den overnevnte
11877 artikkelen. Min venn og gamle kollega Sturle Sunde forteller der:
11880 <p
>I Flora kommune køyrer vi Skulelinux på skular med alt frå
15 til
11881 meir enn
500 elevar. Dei store skulane har eigen tenar, for det er
11882 mest praktisk. Eg, som er driftsansvarleg for heile nettet, ser
11883 sjeldan dei tenarane fysisk, men at dei står der gjer skulane mindre
11884 avhengige av eksterne linjer som er trege eller dyre. Dei minste
11885 skulane har ikkje eigen tenar. Å bruke sentral tenar er heller ikkje
11886 noko problem. Småskulane klarar seg fint med
1 mbit-linje til ein
11887 sentral tenar eller tenaren på ein større skule.
</p
>
11889 <p
>Det beste med Skulelinux er halvtjukke klientar. Dei treng ikkje
11890 harddisk og brukar minimalt med ressursar på tenaren fordi dei køyrer
11891 programma lokalt. Eit klasserom med
30 sju-åtte år gamle maskiner har
11892 mykje meir CPU og RAM totalt enn nokon moderne tenar til under
11893 millionen. Det trengst to kommandoar på den sentrale tenaren for å
11894 oppdatere alle klientane, både tynne og halvtjukke. Vi har ingen
11895 problem med diskar som ryk heller, som var eit problem før fordi
11896 elevane sat og sparka i maskinene. Og dei krev lite bandbreidde i
11897 nettet, so det er fullt mogleg å køyre slike på småskular med trege
11898 linjer mot tenaren på ein større skule.
</p
>
11900 <p
>Flora kommune har nesten
800 Linux-maskiner i sitt skulenett, og
11901 ein person som tek seg av drift av heile nettet, inkludert tenarar,
11902 klientar, operativsystem, programvare, heimekontorløysing og
11903 administrasjon av brukarar.
</p
>
11905 <p
>No skal det seiast at vi ikkje køyrer rein Skulelinux ut av
11906 boksen. Vi har gjort ein del tilpassingar mot noko Novell-greier som
11907 var der frå før, og som har komplisert installasjonen vår. Etter at

11995 the nvidia driver maintainers to fix the driver to start faster, and
11996 while they wait for each other I guess the users end up switching to a
11997 distribution that work for them. I have no idea what the solution is,
11998 but I am pretty sure that waiting for each other is not it.

>A few days ago, parallel booting was enabled in Debian/testing.
12010 The feature seem to hold up pretty well, but three fairly serious
12011 issues are known and should be solved:
12013 <p
><ul
>
12015 <li
>The wicd package seen to
12016 <a href=
"http://bugs.debian.org/
508289">break NFS mounting
</a
> and
12017 <a href=
"http://bugs.debian.org/
581586">network setup
</a
> when
12018 parallel booting is enabled. No idea why, but the wicd maintainer
12019 seem to be on the case.
</li
>
12021 <li
>The nvidia X driver seem to
12022 <a href=
"http://bugs.debian.org/
583312">have a race condition
</a
>
12023 triggered more easily when parallel booting is in effect. The
12024 maintainer is on the case.
</li
>
12026 <li
>The sysv-rc package fail to properly enable dependency based boot
12027 sequencing (the shutdown is broken) when old file-rc users
12028 <a href=
"http://bugs.debian.org/
575080">try to switch back
</a
> to
12029 sysv-rc. One way to solve it would be for file-rc to create
12030 /etc/init.d/.legacy-bootordering, and another is to try to make
12031 sysv-rc more robust. Will investigate some more and probably upload a
12032 workaround in sysv-rc to help those trying to move from file-rc to
12033 sysv-rc get a working shutdown.
</li
>
12035 </ul

>
12037 <p
>All in all not many surprising issues, and all of them seem
12038 solvable before Squeeze is released. In addition to these there are
12039 some packages with bugs in their dependencies and run level settings,
12040 which I expect will be fixed in a reasonable time span.

>After a long break from debian-installer development, I finally
12057 found time today to return to the project. Having to spend less time
12058 working dependency based boot in debian, as it is almost complete now,
12059 definitely helped freeing some time.
</p
>
12061 <p
>A while back, I ran into a problem while working on Debian Edu. We
12062 include some firmware packages on the Debian Edu CDs, those needed to
12063 get disk and network controllers working. Without having these
12064 firmware packages available during installation, it is impossible to
12065 install Debian Edu on the given machine, and because our target group
12066 are non-technical people, asking them to provide firmware packages on
12067 an external medium is a support pain. Initially, I expected it to be
12068 enough to include the firmware packages on the CD to get
12069 debian-installer to find and use them. This proved to be wrong.
12070 Next, I hoped it was enough to symlink the relevant firmware packages
12071 to some useful location on the CD (tried /cdrom/ and
12072 /cdrom/firmware/). This also proved to not work, and at this point I
12073 found time to look at the debian-installer code to figure out what was
12074 going to work.
</p
>
12076 <p
>The firmware loading code is in the hw-detect package, and a closer
12077 look revealed that it would only look for firmware packages outside
12078 the installation media, so the CD was never checked for firmware
12079 packages. It would only check USB sticks, floppies and other
12080 "external
" media devices. Today I changed it to also look in the
12081 /cdrom/firmware/ directory on the mounted CD or DVD, which should
12082 solve the problem I ran into with Debian edu. I also changed it to
12083 look in /firmware/, to make sure the installer also find firmware
12084 provided in the initrd when booting the installer via PXE, to allow us
12085 to provide the same feature in the PXE setup included in Debian
12088 <p
>To make sure firmware deb packages with a license questions are not
12089 activated without asking if the license is accepted, I extended
12090 hw-detect to look for preinst scripts in the firmware packages, and
12091 run these before activating the firmware during installation. The
12092 license question is asked using debconf in the preinst, so this should
12093 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
12106 Edu finally entered the Debian archive. Today, the new
12107 <a href=
"http://packages.qa.debian.org/libp/libpam-mklocaluser.html
">libpam-mklocaluser
</a
>
12108 package was accepted. Two days ago, two other pieces was accepted
12110 <a href=
"http://packages.qa.debian.org/p/pam-python.html
">pam-python
</a
>
12111 package needed by libpam-mklocaluser, and the
12112 <a href=
"http://packages.qa.debian.org/s/sssd.html
">sssd
</a
> package
12113 passed NEW on Monday. In addition, the
12114 <a href=
"http://packages.qa.debian.org/libp/libpam-ccreds.html
">libpam-ccreds
</a
>
12115 package we need is in experimental (version
10-
4) since Saturday, and
12116 hopefully will be moved to unstable soon.
</p
>
12118 <p
>This collection of packages allow for two different setups for
12119 roaming laptops. The traditional setup would be using libpam-ccreds,
12120 nscd and libpam-mklocaluser with LDAP or Kerberos authentication,
12121 which should work out of the box if the configuration changes proposed
12122 for nscd in
<a href=
"http://bugs.debian.org/
485282">BTS report
12123 #
485282</a
> is implemented. The alternative setup is to use sssd with
12124 libpam-mklocaluser to connect to LDAP or Kerberos and let sssd take
12125 care of the caching of passwords and group information.
</p
>
12127 <p
>I have so far been unable to get sssd to work with the LDAP server
12128 at the University, but suspect the issue is some SSL/GnuTLS related
12129 problem with the server certificate. I plan to update the Debian
12130 package to version
1.2, which is scheduled for next week, and hope to
12131 find time to make sure the next release will include both the
12132 Debian/Ubuntu specific patches. Upstream is friendly and responsive,
12133 and I am sure we will find a good solution.
</p
>
12135 <p
>The idea is to set up the roaming laptops to authenticate using
12136 LDAP or Kerberos and create a local user with home directory in /home/
12137 when a usre in LDAP logs in via KDM or GDM for the first time, and
12138 cache the password for offline checking, as well as caching group
12139 memberhips and other relevant LDAP information. The
12140 libpam-mklocaluser package was created to make sure the local home
12141 directory is in /home/, instead of /site/server/directory/ which would
12142 be the home directory if pam_mkhomedir was used. To avoid confusion
12143 with support requests and configuration, we do not want local laptops
12144 to have users in a path that is used for the same users home directory
12145 on the home directory servers.
</p
>
12147 <p
>One annoying problem with gdm is that it do not show the PAM
12148 message passed to the user from libpam-mklocaluser when the local user
12149 is created. Instead gdm simply reject the login with some generic
12150 message. The message is shown in kdm, ssh and login, so I guess it is
12151 a bug in gdm. Have not investigated if there is some other message
12152 type that can be used instead to get gdm to also show the message.

>For some years now, I have wondered how we should handle laptops in
12310 Debian Edu. The Debian Edu infrastructure is mostly designed to
12311 handle stationary computers, and less suited for computers that come
12314 <p
>Now I finally believe I have an sensible idea on how to adjust
12315 Debian Edu for laptops, by introducing a new profile for them, for
12316 example called Roaming Workstations. Here are my thought on this.
12317 The setup would consist of the following:
</p
>
12321 <li
>During installation, the user name of the owner / primary user of
12322 the laptop is requested and a local home directory is set up for
12323 the user, with uid and gid information fetched from the LDAP
12324 server. This allow the user to work also when offline. The
12325 central home directory can be available in a subdirectory on
12326 request, for example mounted via CIFS. It could be mounted
12327 automatically when a user log in while on the Debian Edu network,
12328 and unmounted when the machine is taken away (network down,
12329 hibernate, etc), it can be set up to do automatic mounting on
12330 request (using autofs), or perhaps some GUI button on the desktop
12331 can be used to access it when needed. Perhaps it is enough to use
12332 the fish protocol in KDE?
</li
>
12334 <li
>Password checking is set up to use LDAP or Kerberos
12335 authentication when the machine is on the Debian Edu network, and
12336 to cache the password for offline checking when the machine unable
12337 to reach the LDAP or Kerberos server. This can be done using
12338 <a href=
"http://www.padl.com/OSS/pam_ccreds.html
">libpam-ccreds
</a
>
12339 or the Fedora developed
12340 <a href=
"https://fedoraproject.org/wiki/Features/SSSD
">System
12341 Security Services Daemon
</a
> packages.
</li
>
12343 <li
>File synchronisation with the central home directory is set up
12344 using a shared directory in both the local and the central home
12345 directory, using unison.
</li
>
12347 <li
>Printing should be set up to print to all printers broadcasting
12348 their existence on the local network, and should then work out of
12349 the box with CUPS. For sites needing accurate printer quotas, some
12350 system with Kerberos authentication or printing via ssh could be
12351 implemented.
</li
>
12353 <li
>For users that should have local root access to their laptop,
12354 sudo should be used to allow this to the local user.
</li
>
12356 <li
>It would be nice if user and group information from LDAP is
12357 cached on the client, but given that there are entries for the
12358 local user and primary group in /etc/, it should not be needed.
</li
>
12362 <p
>I believe all the pieces to implement this are in Debian/testing at
12363 the moment. If we work quickly, we should be able to get this ready
12364 in time for the Squeeze release to freeze. Some of the pieces need
12365 tweaking, like libpam-ccreds should get support for pam-auth-update
12366 (
<a href=
"http://bugs.debian.org/
566718">#
566718</a
>) and nslcd (or
12367 perhaps debian-edu-config) should get some integration code to stop
12368 its daemon when the LDAP server is unavailable to avoid long timeouts
12369 when disconnected from the net. If we get Kerberos enabled, we need
12370 to make sure we avoid long timeouts there too.

12383 NUUG presentation
</a
> about Kerberos was inspiring, and reminded me
12384 about the need to start using Kerberos in Skolelinux. Setting up a
12385 Kerberos server seem to be straight forward, and if we get this in
12386 place a long time before the Squeeze version of Debian freezes, we
12387 have a chance to migrate Skolelinux away from NFSv3 for the home
12388 directories, and over to an architecture where the infrastructure do
12389 not have to trust IP addresses and machines, and instead can trust
12390 users and cryptographic keys instead.
</p
>
12392 <p
>A challenge will be integration and administration. Is there a
12393 Kerberos implementation for Debian where one can control the
12394 administration access in Kerberos using LDAP groups? With it, the
12395 school administration will have to maintain access control using flat
12396 files on the main server, which give a huge potential for errors.
</p
>
12398 <p
>A related question I would like to know is how well Kerberos and
12399 pam-ccreds (offline password check) work together. Anyone know?
</p
>
12401 <p
>Next step will be to use Kerberos for access control in Lwat and
12402 Nagios. I have no idea how much work that will be to implement. We
12403 would also need to document how to integrate with Windows AD, as such
12404 shared network will require two Kerberos realms that need to cooperate
12405 to work properly.
</p
>
12407 <p
>I believe a good start would be to start using Kerberos on the
12408 skolelinux.no machines, and this way get ourselves experience with
12409 configuration and integration. A natural starting point would be
12410 setting up ldap.skolelinux.no as the Kerberos server, and migrate the
12411 rest of the machines from PAM via LDAP to PAM via Kerberos one at the
12414 <p
>If you would like to contribute to get this working in Skolelinux,
12415 I recommend you to see the video recording from yesterdays NUUG
12416 presentation, and start using Kerberos at home. The video show show
12417 up in a few days.

>6 years ago, as part of the Debian Edu development I am involved
12427 in, I asked for a hook in the kdm and gdm setup to run scripts as root
12428 when the user log out. A bug was submitted against the xfree86-common
12429 package in
2004 (
<a href=
"http://bugs.debian.org/
230422">#
230422</a
>),
12430 and revisited every time Debian Edu was working on a new release.
12431 Today, this finally paid off.
</p
>
12433 <p
>The framework for this feature was today commited to the git
12434 repositry for the xorg package, and the git repository for xdm has
12435 been updated to use this framework. Next on my agenda is to make sure
12436 kdm and gdm also add code to use this framework.
</p
>
12438 <p
>In Debian Edu, we want to ability to run commands as root when the
12439 user log out, to get rid of runaway processes and do general cleanup
12440 after a user. With this framework in place, we finally can do that in
12441 a generic way that work with all display managers using this
12442 framework. My goal is to get all display managers in Debian use it,
12443 similar to how they use the Xsession.d framework today.

>One of the new features in the next Debian/Lenny based release of
12475 Debian Edu/Skolelinux, which is scheduled for release in the next few
12476 days, is automatic configuration of the service monitoring system
12477 Nagios. The previous release had automatic configuration of trend
12478 analysis using Munin, and this Lenny based release take that a step
12481 <p
>When installing a Debian Edu Main-server, it is automatically
12482 configured as a Munin and Nagios server. In addition, it is
12483 configured to be a server for the
12484 <a href=
"http://wiki.debian.org/DebianEdu/HowTo/SiteSummary
">SiteSummary
12485 system
</a
> I have written for use in Debian Edu. The SiteSummary
12486 system is inspired by a system used by the University of Oslo where I
12487 work. In short, the system provide a centralised collector of
12488 information about the computers on the network, and a client on each
12489 computer submitting information to this collector. This allow for
12490 automatic information on which packages are installed on each machine,
12491 which kernel the machines are using, what kind of configuration the
12492 packages got etc. This also allow us to automatically generate Munin
12493 and Nagios configuration.
</p
>
12495 <p
>All computers reporting to the sitesummary collector with the
12496 munin-node package installed is automatically enabled as a Munin
12497 client and graphs from the statistics collected from that machine show
12498 up automatically on http://www/munin/ on the Main-server.
</p
>
12500 <p
>All non-laptop computers reporting to the sitesummary collector are
12501 automatically monitored for network presence (ping and any network
12502 services detected). In addition, all computers (also laptops) with
12503 the nagios-nrpe-server package installed and configured the way
12504 sitesummary would configure it, are monitored for full disks, software
12505 raid status, swap free and other checks that need to run locally on
12506 the machine.
</p
>
12508 <p
>The result is that the administrator on a school using Debian Edu
12509 based on Lenny will be able to check the health of his installation
12510 with one look at the Nagios settings, without having to spend any time
12511 keeping the Nagios configuration up-to-date.
</p
>
12513 <p
>The only configuration one need to do to get Nagios up and running
12514 is to set the password used to get access via HTTP. The system
12515 administrator need to run
"<tt
>htpasswd /etc/nagios3/htpasswd.users
12516 nagiosadmin
</tt
>" to create a nagiosadmin user and set a password for
12517 it to be able to log into the Nagios web pages. After that,
12518 everything is taken care of.

12588 Edu/Skolelinux development gathering. I got a bit done tuning the
12589 desktop, and looked into the dynamic service location protocol
12590 implementation avahi. It look like it could be useful for us. Almost
12591 30 people participated, and I believe it was a great environment to
12592 get to know the Skolelinux system. Walter Bender, involved in the
12593 development of the Sugar educational platform, presented his stuff and
12594 also helped me improve my OLPC installation. He also showed me that
12595 his Turtle Art application can be used in standalone mode, and we
12596 agreed that I would help getting it packaged for Debian. As a
12597 standalone application it would be great for Debian Edu. We also
12598 tried to get the video conferencing working with two OLPCs, but that
12599 proved to be too hard for us. The application seem to need more work

12733 types I would expect to work with any free software player (like
12734 video/ogg), just do not work. And simple formats like the
12735 audio/x-mplegurl format (m3u playlists), just isn
't supported by the
12736 totem and vlc plugins. I hope the situation will improve soon. No
12737 wonder sites use the proprietary Adobe flash to play video.
