</a

18 <a href=
"https://lists.debian.org/debian-edu/

20 might pick up the idea and run with it, but this has not happened as
21 far as I can tell, so here we are… This time the announcement of a new

><strong
>Who are you, and how do you spend your days?
</strong
></p
>
29 <p
>My name is Yvan MASSON, I live in France. I have my own one person
30 business in computer services. The work consist of visiting my
31 customers (person
's home, local authority, small business) to give
32 advise, install computers and software, fix issues, and provide
33 computing usage training. I spend the rest of my time enjoying my
34 family and promoting free software.
</p
>
36 <p
><strong
>What is your approach for promoting free
37 software?
</strong
></p
>
39 <p
>When I think that free software could be suitable for someone, I
40 explain what it is, with simple words, give a few known examples, and
41 explain that while there is no fee it is a viable alternative in many
42 situations. Most people are receptive when you explain how it is
43 better (I simplify arguments here, I know that it is not so simple):
44 Linux works on older hardware, there are no viruses, and the software
45 can be audited to ensure user is not spied upon. I think the most
46 important is to keep a clear but moderated speech: when you try to
47 convince too much, people feel attacked and stop listening.
</p
>
49 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
50 project?
</strong
></p
>
52 <p
>I can not remember how I first heard of Skolelinux / Debian Edu,
53 but probably on planet.debian.org. As I have been working for a
54 school, I have interest in this type of project.
56 <p
>The school I am involved in is a school for
"children
" between
14
57 and
18 years old. The French government has recommended free software
58 since
2012, but they do not always use free software themselves. The
59 school computers are still using the Windows operating system, but all
60 of them have the classic set of free software: Firefox ESR,
61 LibreOffice (with the excellent extension Grammalecte that indicates
62 French grammatical errors), SumatraPDF, Audacity,
7zip, KeePass2, VLC,
65 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
66 Edu?
</strong
></p
>
68 <p
>It is free software! Built on Debian, I am sure that users are not
69 spied upon, and that it can run on low end hardware. This last point
70 is very important, because we really need to improve
"green IT
". I do
71 not know enough about Skolelinux / Debian Edu to tell how it is better
72 than another free software solution, but what I like is the
"all in
73 one
" solution: everything has been thought of and prepared to ease
74 installation and usage.
</p
>
76 <p
>I like Free Software because I hate using something that I can not
77 understand. I do not say that I can understand everything nor that I
78 want to understand everything, but knowing that someone / some company
79 intentionally prevents me from understanding how things work is really
80 unacceptable to me.
</p
>
82 <p
>Secondly, and more importantly, free software is a requirement to
83 prevent abuses regarding human rights and environmental care.
84 Humanity can not rely on tools that are in the hands of small group of

><strong
>What do you see as the disadvantages of Skolelinux / Debian
88 Edu?
</strong
></p
>
90 <p
>Again, I don
't know this project enough. Maybe a dedicated website?
91 Debian wiki works well for documentation, but is not very appealing to
92 someone discovering the project. Also, as Skolelinux / Debian Edu uses
93 OpenLDAP, it probably means that Windows workstations cannot use
94 centralized authentication. Maybe the project could use Samba as an
95 Active Directory domain controller instead, allowing Windows desktop
96 usage when necessary.
</p
>
98 <p
>(Editors note: In fact Windows workstations can
99 <a href=
"https://wiki.debian.org/DebianEdu/Documentation/Buster/HowTo/Samba
">use
100 the centralized authentication in a Debian Edu setup
</a
>, at least for
101 some versions of Windows, but the fact that this is not well known can
102 be seen as an indication of the need for better documentation and
103 marketing. :)
</p
>
105 <p
><strong
>Which free software do you use daily?
</strong
></p
>
107 <p
>Nothing original: Debian testing/sid with Gnome desktop, Firefox,
108 Thunderbird, LibreOffice…
</p
>
110 <p
><strong
>Which strategy do you believe is the right one to use to
111 get schools to use free software?
</strong
></p
>
113 <p
>Every effort to spread free software into schools is important,
114 whatever it is. But I think, at least where I live, that IT
115 professionals maintaining schools networks are still very
"Microsoft
116 centric
". Schools will use any working solution, but they need people
117 to install and maintain it. How to make these professionals sensitive
118 about free software and train them with solutions like Debian Edu /
119 Skolelinux is a really good question :-)

>Two years ago, I did some experiments with eatmydata and the Debian
129 installation system, observing how using
130 <a href=
"https://people.skolelinux.org/pere/blog/Speeding_up_the_Debian_installer_using_eatmydata_and_dpkg_divert.html
">eatmydata
131 could speed up the installation
</a
> quite a bit. My testing measured
132 speedup around
20-
40 percent for Debian Edu, where we install around
133 1000 packages from within the installer. The eatmydata package
134 provide a way to disable/delay file system flushing. This is a bit
135 risky in the general case, as files that should be stored on disk will
136 stay only in memory a bit longer than expected, causing problems if a
137 machine crashes at an inconvenient time. But for an installation, if
138 the machine crashes during installation the process is normally
139 restarted, and avoiding disk operations as much as possible to speed
140 up the process make perfect sense.
142 <p
>I added code in the Debian Edu specific installation code to enable
143 <a href=
"https://tracker.debian.org/pkg/libeatmydata
">eatmydata
</a
>,
144 but did not have time to push it any further. But a few months ago I
145 picked it up again and worked with the libeatmydata package maintainer
146 Mattia Rizzolo to make it easier for everyone to get this installation
147 speedup in Debian. Thanks to our cooperation There is now an
148 eatmydata-udeb package in Debian testing and unstable, and simply
149 enabling/installing it in debian-installer (d-i) is enough to get the
150 quicker installations. It can be enabled using preseeding. The
151 following untested kernel argument should do the trick:
</p
>
153 <blockquote
><pre
>
154 preseed/early_command=
"anna-install eatmydata-udeb
"
155 </pre
></blockquote
>
157 <p
>This should ask d-i to install the package inside the d-i
158 environment early in the installation sequence. Having it installed
159 in d-i in turn will make sure the relevant scripts are called just
160 after debootstrap filled /target/ with the freshly installed Debian
161 system to configure apt to run dpkg with eatmydata. This is enough to
162 speed up the installation process. There is a proposal to
163 <a href=
"https://bugs.debian.org/
841153">extend the idea a bit further
164 by using /etc/ld.so.preload instead of apt.conf
</a
>, but I have not
165 tested its impact.

177 multimedia player in Debian claimed to support most file formats /

</a

179 the various players claimed support for. The range was from
55 to
130
180 MIME types. I suspect most media formats are supported by all
181 players, but this is not really reflected in the MimeTypes values in
182 their desktop files. There are probably also some bogus MIME types
183 listed, but it is hard to identify which one this is.

185 <p
>Anyway, in the mean time I got in touch with upstream for some of
186 the players suggesting to add more MIME types to their desktop files,
187 and decided to spend some time myself improving the situation for my
188 favorite media player VLC. The fixes for VLC entered Debian unstable
189 yesterday. The complete list of MIME types can be seen on the

196 several of the formats currently listed as working only with vlc,

219 <p
>A few years ago, I had a look at the media support for Browser
220 plugins in Debian, to get an idea which plugins to include in Debian
221 Edu. I created a script to extract the set of supported MIME types
222 for each plugin, and used this to find out which multimedia browser
223 plugin supported most file formats / media types.
224 <a href=
"https://wiki.debian.org/DebianEdu/BrowserMultimedia

226 not been updated for a while. But browser plugins are less relevant
227 these days, so I thought it was time to look at standalone

>A few days ago I was tired of VLC not being listed as a viable
231 player when I wanted to play videos from the Norwegian National
232 Broadcasting Company, and decided to investigate why. The cause is a
233 <a href=
"https://bugs.debian.org/
822245">missing MIME type in the VLC
234 desktop file
</a
>. In the process I wrote a script to compare the set
235 of MIME types announced in the desktop file and the browser plugin,
236 only to discover that there is quite a large difference between the
237 two for VLC. This discovery made me dig up the script I used to
238 compare browser plugins, and adjust it to compare desktop files
239 instead, to try to figure out which multimedia player in Debian

339 imply, public domain and permissively licensed software can lead to
340 the production of more proprietary software as people discover useful
341 software, extend it and or incorporate it into their hardware or
342 software products. Copyleft licenses such as the GNU GPL were created
343 to close off this avenue to the production of proprietary software but
344 such licenses are not enough. With the ongoing adoption of Free
345 Software by individuals and groups, inevitably the community
's
346 expectations of license compliance are violated, usually out of
347 ignorance of the way Free Software works, but not always. As Karen

436 Debian Edu - sometimes also known as
"Skolelinux
" - is a complete
437 operating system for schools, universities and other
438 organisations. Through its pre- prepared installation profiles
439 administrators can install servers, workstations and laptops which
440 will work in harmony on the school network. With Debian Edu, the
441 teachers themselves or their technical support staff can roll out a
442 complete multi-user, multi-machine study environment within hours or
445 Debian Edu is already in use at several hundred schools all over the
446 world, particularly in Germany, Spain and Norway. Installations come
447 with hundreds of applications pre-installed, plus the whole Debian
448 archive of thousands of compatible packages within easy reach.

563 == About Debian Edu / Skolelinux ==
565 Debian Edu, also known as Skolelinux, is a Linux distribution based on
566 Debian providing an out-of-the box environment of a completely
567 configured school network. Directly after installation a school server
568 running all services needed for a school network is set up just
569 waiting for users and machines being added via GOsa², a comfortable
570 Web-UI. A netbooting environment is prepared using PXE, so after
571 initial installation of the main server from CD or USB stick all other
572 machines can be installed via the network. The provided school server
573 provides LDAP database and Kerberos authentication service,
574 centralized home directories, DHCP server, web proxy and many other
575 services. The desktop contains more than
60 educational software
576 packages and more are available from the Debian archive, and schools
577 can choose between KDE, GNOME, LXDE, Xfce and MATE desktop
582 The Debian Project was founded in
1993 by Ian Murdock to be a truly
583 free community project. Since then the project has grown to be one of
584 the largest and most influential open source projects. Thousands of
585 volunteers from all over the world work together to create and
586 maintain Debian software. Available in
70 languages, and supporting a
587 huge range of computer types, Debian calls itself the universal
592 Thanks to everyone making Debian and Debian Edu / Skolelinux happen!

>It was a surprise to me to learn that project to create a complete
604 computer system for schools I
've involved in,
605 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>, was
606 being used in India. But apparently it is, and I managed to get an
607 interview with one of the friends of the project there, Shirish
610 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
612 <p
>My name is Shirish Agarwal. Based out of the educational and
613 historical city of Pune, from the western state of Maharashtra, India.
614 My bread comes from giving training, giving policy tips,
615 installations on free software to mom and pop shops in different
616 fields from Desktop publishing to retail shops as well as work with
617 few software start-ups as well.
</p
>
619 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
620 project?
</strong
></p
>
622 <p
>It started innocently enough. I have been using Debian for a few
623 years and in one local minidebconf / debutsav I was asked if there was
624 anything for schools or education. I had worked / played with free
625 educational softwares such as Gcompris and Stellarium for my many
626 nieces and nephews so researched and found Debian Edu or Skolelinux as
627 it was known then. Since then I have started using the various
628 education meta-packages provided by the project.
</p
>
630 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
631 Edu?
</strong
></p
>
633 <p
>It
's closest I have seen where a package full of educational
634 software are packed, which are free and open (both literally and
635 figuratively). Even if I take the simplest software which is
636 gcompris, the number of activities therein are amazing. Another one of
637 the softwares that I have liked for a long time is stellarium. Even
638 pysycache is cool except for couple of issues I encountered
639 <a href=
"https://bugs.debian.org/
781841">#
781841</a
> and
640 <a href=
"https://bugs.debian.org/
781842">#
781842</a
>.
</p
>
642 <p
>I prefer software installed on the system over web based solutions,
643 as a web site can disappear any time but the software on disk has the
644 possibility of a larger life span. Of course with both it
's more a
645 question if it has enough users who make it fun or sustainable or both
646 for the developer per-se.
</p
>
648 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
649 Edu?
</strong
></p
>
651 <p
>I do see that the Debian Edu team seems to be short-handed and I
652 think more efforts should be made to make it popular and ask and take
653 help from people and the larger community wherever possible.
</p
>
655 <p
>I don
't see any disadvantage to use Skolelinux apart from the fact
656 that most apps. are generic which is good or bad how you see it.
657 However, saying that I do acknowledge the fact that the canvas is
658 pretty big and there are lot of interesting ideas that could be done
659 but for reasons not known not done or if done I don
't know about them.
660 Let me share some of the ideas (these are more upstream based but
661 still) I have had for a long time :
</p
>
663 <p
>1. Classical maths question of two trains in opposing directions
664 each running @x kmph/mph at y distance, when they will meet and how
665 far would each travel and similar questions like these.
667 <p
>The computer is a fantastic system where questions like these can
668 be drawn, animated and the methodology and answers teased out in
669 interactive manner. While sites such as the
670 <a href=
"http://mathforum.org/dr.math/faq/faq.two.trains.html
">Ask
671 Dr. Math FAQ on The Two Trains problem
</a
> (as an example or point of
672 inspiration) can be used there is lot more that can be done. I dunno
673 if there is a free software which does something like this. The idea
674 being a blend of objects + animation + interaction which does
675 this. The whole interaction could be gamified with points or sounds or
676 colourful celebration whenever the user gets even part of the question
677 or/and methodology right. That would help reinforce good behaviour.
678 This understanding could be used to share/showcase everything from how
679 the first wheel came to be, to evolution to how astronomy started,
680 psychics and everything in-between.
</p
>
682 <p
>One specific idea in the train part was having the Linux mascot on
683 one train and the BSD or GNU mascot on the other train and they
684 meeting somewhere in-between. Characters from blender movies could
685 also be used.
</p
>
687 <p
>2. Loads of crossword-puzzles with reference to subjects: We have
688 enormous data sets in Wikipedia and Wikitionary. I don
't think it
689 should be a big job to design crossword puzzles. Using categories and
690 sub-categories it should be doable to have Q
&A single word answers
691 from the existing data-sets. What would make it easy or hard could be
692 the length of the word + existence of many or few vowels depending on
693 the user
's input.
</p
>
695 <p
>3. Jigsaw puzzles - We already have a great software called
696 palapeli with number of slicers making it pretty interesting. What
697 needs to be done is to download large number of public domain and
698 copyleft images, tease and use IPTC tags to categorise them into
699 nature, history etc. and let it loose. This could turn to be really
700 huge collection of images. One source could be taken from
701 commons.wikimedia.org, others could be huge collection of royalty-free
702 stock photos. Potential is immense.
</p
>
704 <p
>Apart from this, free software suffers in two directions, we lag
705 both in development (of using new features per-se) and maintenance a
706 lot. This is more so in educational software as these applications
707 need to be timely and the opportunity cost of missing deadlines is
708 immense. If we are able to solve issues of funding for development and
709 maintenance of such software I don
't see any big difficulties. I know
710 of few start-ups in and around India who would love to develop and
711 maintain such software if funding issues could be solved.
</p
>
713 <p
><strong
>Which free software do you use daily?
</strong
></p
>
715 <p
>That would be huge list. Some of the softwares are obviously apt,
716 aptitude, debdelta, leafpad, the shell of course (zsh nowadays),
717 quassel for IRC. In games I use shisen-sho while card-games are evenly
718 between kpat and Aiselriot. In desktops it
's a tie between
719 gnome-flashback and mate.
</p
>
721 <p
><strong
>Which strategy do you believe is the right one to use to
722 get schools to use free software?
</strong
></p
>
724 <p
>I think it should first start with using specific FOSS apps. in
725 whatever environment they are. If it
's MS-Windows or Mac so be it.
726 Once they are habitual with the apps. and there is buy-in from the
727 school management then it could be installed anywhere. Most of the
728 people now understand the concept of a repository because of the
729 various online stores so it isn
't hard to convince on that front.
</p
>
731 <p
>What is harder is having enough people with technical skills and
732 passion to service them. If you get buy-in from one or two teachers
733 then ideas like above could also be asked to be done as a project as
736 <p
>I think where we fall short more than anything is in marketing. For
737 instance, Debian has this whole range of fonts in its archive but
738 there isn
't even a page where all those different fonts in the La
739 Ipsum format could be tried out for newcomers.
</p
>
741 <p
>One of the issues faced constantly in installations is with updates
742 and upgrades. People have this myth that each update and upgrade
743 means the user interface will / has to change. I have seen this
744 innumerable times. That perhaps is one of the reasons which browsers
745 like Iceweasel / Firefox change user interfaces so much, not because
746 it might be needed or be functional but because people believe that
747 changed user interfaces are better. This, can easily be pointed with
748 the user interfaces changed with almost every MS-Windows and Mac OS
751 <p
>The problems with Debian Edu for deployment are many. The biggest
752 is the huge gap between what is taught in schools and what Debian Edu
755 <p
>Me and my friends did teach on week-ends in a government school for
757 <a href=
"https://flossexperiences.wordpress.com/
2012/
10/
08/sharings/
">gathered
758 some experience
</a
> there. Some of the things we learnt/discovered
759 there was :
</p
>
763 <li
>Most of the teachers are very territorial about their subjects
764 and they do not want you to teach anything out of the
765 portion/syllabus given.
</li
>
767 <li
>They want any activity on the system in accordance to whatever
768 is in the syllabus.
</li
>
770 <li
>There are huge barriers both with the English language and at
771 times with objects or whatever. An example, let
's say in gcompris
772 you have objects falling down and you have to name them and let
's
773 say the falling object is a hat or a fedora hat, this would not be
774 as recognizable as say a
775 <a href=
"https://en.wikipedia.org/wiki/Puneri_Pagadi
">Puneri
776 Pagdi
</a
> so there is need to inject local objects, words wherever
777 possible. Especially for word-games there are so many hindi words
778 which have become part of english vocabulary (for instance in
779 parley), those could be made into a hinglish collection or
780 something but that is something for upstream to do.

980 powerful desktop with education software, a central server providing
981 web pages, user database, user home directories, central login and PXE
982 boot of both clients without disk and the installation to install Debian
983 Edu on machines with disk (and a few other services perhaps to small
984 to mention here). We in the Debian Edu team are currently working on
985 the Jessie based version, trying to get everything in shape before the
986 freeze, to avoid having to maintain our own package repository in the
988 <a href=
"https://wiki.debian.org/DebianEdu/Status/Jessie
">current
989 status
</a
> can be seen on the Debian wiki, and there is still heaps of
990 work left. Some fatal problems block testing, breaking the installer,
991 but it is possible to work around these to get anyway. Here is a
992 recipe on how to get the installation limping along.
</p
>
994 <p
>First, download the test ISO via
995 <a href=
"ftp://ftp.skolelinux.no/cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-
1.iso
">ftp
</a
>,
996 <a href=
"http://ftp.skolelinux.no/cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-
1.iso
">http
</a
>
998 ftp.skolelinux.org::cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-
1.iso).
999 The ISO build was broken on Tuesday, so we do not get a new ISO every
1000 12 hours or so, but thankfully the ISO we already got we are able to
1001 install with some tweaking.
</p
>
1003 <p
>When you get to the Debian Edu profile question, go to tty2
1004 (use Alt-Ctrl-F2), run
</p
>
1006 <p
><blockquote
><pre
>
1007 nano /usr/bin/edu-eatmydata-install
1008 </pre
></blockquote
></p
>
1010 <p
>and add
'exit
0' as the second line, disabling the eatmydata
1011 optimization. Return to the installation, select the profile you want
1012 and continue. Without this change, exim4-config will fail to install
1013 due to a known bug in eatmydata.
</p
>
1015 <p
>When you get the grub question at the end, answer /dev/sda (or if
1016 this do not work, figure out what your correct value would be. All my
1017 test machines need /dev/sda, so I have no advice if it do not fit
1018 your need.
</p
>
1020 <p
>If you installed a profile including a graphical desktop, log in as
1021 root after the initial boot from hard drive, and install the
1022 education-desktop-XXX metapackage. XXX can be kde, gnome, lxde, xfce
1023 or mate. If you want several desktop options, install more than one
1024 metapackage. Once this is done, reboot and you should have a working
1025 graphical login screen. This workaround should no longer be needed
1026 once the education-tasks package version
1.801 enter testing in two
1029 <p
>I believe the ISO build will start working on two days when the new
1030 tasksel package enter testing and Steve McIntyre get a chance to
1031 update the debian-cd git repository. The eatmydata, grub and desktop
1032 issues are already fixed in unstable and testing, and should show up
1033 on the ISO as soon as the ISO build start working again. Well the
1034 eatmydata optimization is really just disabled. The proper fix
1035 require an upload by the eatmydata maintainer applying the patch
1036 provided in bug
<a href=
"https://bugs.debian.org/
702711">#
702711</a
>.
1037 The rest have proper fixes in unstable.
</p
>
1039 <p
>I hope this get you going with the installation testing, as we are
1040 quickly running out of time trying to get our Jessie based
1041 installation ready before the distribution freeze in a month.

1051 a lot quicker. When we install more than

1052 <a href=
"http://www.skolelinux.org/
">Skolelinux / Debian Edu
</a
> using
1053 tasksel in the installer, unpacking the binary packages take forever.
1054 A part of the slow I/O issue was discussed in
1055 <a href=
"https://bugs.debian.org/
613428">bug #
613428</a
> about too
1056 much file system sync-ing done by dpkg, which is the package
1057 responsible for unpacking the binary packages. Other parts (like code
1058 executed by postinst scripts) might also sync to disk during
1059 installation. All this sync-ing to disk do not really make sense to
1060 me. If the machine crash half-way through, I start over, I do not try
1061 to salvage the half installed system. So the failure sync-ing is
1062 supposed to protect against, hardware or system crash, is not really
1063 relevant while the installer is running.
</p
>
1065 <p
>A few days ago, I thought of a way to get rid of all the file
1066 system sync()-ing in a fairly non-intrusive way, without the need to
1067 change the code in several packages. The idea is not new, but I have
1068 not heard anyone propose the approach using dpkg-divert before. It
1069 depend on the small and clever package
1070 <a href=
"https://packages.qa.debian.org/eatmydata
">eatmydata
</a
>, which
1071 uses LD_PRELOAD to replace the system functions for syncing data to
1072 disk with functions doing nothing, thus allowing programs to live
1073 dangerous while speeding up disk I/O significantly. Instead of
1074 modifying the implementation of dpkg, apt and tasksel (which are the
1075 packages responsible for selecting, fetching and installing packages),
1076 it occurred to me that we could just divert the programs away, replace
1077 them with a simple shell wrapper calling
1078 "eatmydata
&nbsp;$program
&nbsp;$@
", to get the same effect.
1079 Two days ago I decided to test the idea, and wrapped up a simple
1080 implementation for the Debian Edu udeb.
</p
>
1082 <p
>The effect was stunning. In my first test it reduced the running
1083 time of the pkgsel step (installing tasks) from
64 to less than
44
1084 minutes (
20 minutes shaved off the installation) on an old Dell
1085 Latitude D505 machine. I am not quite sure what the optimised time
1086 would have been, as I messed up the testing a bit, causing the debconf
1087 priority to get low enough for two questions to pop up during
1088 installation. As soon as I saw the questions I moved the installation
1089 along, but do not know how long the question were holding up the
1090 installation. I did some more measurements using Debian Edu Jessie,
1091 and got these results. The time measured is the time stamp in
1092 /var/log/syslog between the
"pkgsel: starting tasksel
" and the
1093 "pkgsel: finishing up
" lines, if you want to do the same measurement
1094 yourself. In Debian Edu, the tasksel dialog do not show up, and the
1095 timing thus do not depend on how quickly the user handle the tasksel

1144 <p
>The test is done using a netinst ISO on a USB stick, so some of the
1145 time is spent downloading packages. The connection to the Internet
1146 was
100Mbit/s during testing, so downloading should not be a
1147 significant factor in the measurement. Download typically took a few
1148 seconds to a few minutes, depending on the amount of packages being
1149 installed.
</p
>
1151 <p
>The speedup is implemented by using two hooks in
1152 <a href=
"https://www.debian.org/devel/debian-installer/
">Debian
1153 Installer
</a
>, the pre-pkgsel.d hook to set up the diverts, and the
1154 finish-install.d hook to remove the divert at the end of the
1155 installation. I picked the pre-pkgsel.d hook instead of the
1156 post-base-installer.d hook because I test using an ISO without the
1157 eatmydata package included, and the post-base-installer.d hook in
1158 Debian Edu can only operate on packages included in the ISO. The
1159 negative effect of this is that I am unable to activate this
1160 optimization for the kernel installation step in d-i. If the code is
1161 moved to the post-base-installer.d hook, the speedup would be larger
1162 for the entire installation.
</p
>
1164 <p
>I
've implemented this in the
1165 <a href=
"https://packages.qa.debian.org/debian-edu-install
">debian-edu-install
</a
>
1166 git repository, and plan to provide the optimization as part of the
1167 Debian Edu installation. If you want to test this yourself, you can
1168 create two files in the installer (or in an udeb). One shell script
1169 need do go into /usr/lib/pre-pkgsel.d/, with content like this:

1240 current debian-installer coordinators find it useful enough. It also
1241 depend on the side effects of the change. I
'm not aware of any, but I
1242 guess we will see if the change is safe after some more testing.
1243 Perhaps there is some package in Debian depending on sync() and
1244 fsync() having effect? Perhaps it should go into its own udeb, to
1245 allow those of us wanting to enable it to do so without affecting
1248 <p

2014-
09-
24: Since a few days ago, enabling this optimization

30 years in this job.
30 years ago I started to

1285 administrator for a small computer network, today based on Ubuntu
1286 Server (Samba, OpenVPN). For her daily work she has to use Windows

1292 Linux server with
6 Windows clients and
10 persons (teacher of

>The
<a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
1362 project
</a
> provide an instruction manual for teachers, system
1363 administrators and other users that contain useful tips for setting up
1364 and maintaining a Debian Edu installation. This text is about how the
1365 text processing of this manual is handled in the project.
</p
>
1367 <p
>One goal of the project is to provide information in the native
1368 language of its users, and for this we need to handle translations.
1369 But we also want to make sure each language contain the same
1370 information, so for this we need a good way to keep the translations
1371 in sync. And we want it to be easy for our users to improve the
1372 documentation, avoiding the need to learn special formats or tools to
1373 contribute, and the obvious way to do this is to make it possible to
1374 edit the documentation using a web browser. We also want it to be
1375 easy for translators to keep the translation up to date, and give them
1376 help in figuring out what need to be translated. Here is the list of
1377 tools and the process we have found trying to reach all these
1380 <p
>We maintain the authoritative source of our manual in the
1381 <a href=
"https://wiki.debian.org/DebianEdu/Documentation/Wheezy/
">Debian
1382 wiki
</a
>, as several wiki pages written in English. It consist of one
1383 front page with references to the different chapters, several pages
1384 for each chapter, and finally one
"collection page
" gluing all the
1385 chapters together into one large web page (aka
1386 <a href=
"https://wiki.debian.org/DebianEdu/Documentation/Wheezy/AllInOne
">the
1387 AllInOne page
</a
>). The AllInOne page is the one used for further
1388 processing and translations. Thanks to the fact that the
1389 <a href=
"http://moinmo.in/
">MoinMoin
</a
> installation on
1390 wiki.debian.org support exporting pages in
1391 <a href=
"http://www.docbook.org/
">the Docbook format
</a
>, we can fetch
1392 the list of pages to export using the raw version of the AllInOne
1393 page, loop over each of them to generate a Docbook XML version of the
1394 manual. This process also download images and transform image
1395 references to use the locally downloaded images. The generated
1396 Docbook XML files are slightly broken, so some post-processing is done
1397 using the
<tt
>documentation/scripts/get_manual
</tt
> program, and the
1398 result is a nice Docbook XML file (debian-edu-wheezy-manual.xml) and
1399 a handfull of images. The XML file can now be used to generate PDF, HTML
1400 and epub versions of the English manual. This is the basic step of
1401 our process, making PDF (using dblatex), HTML (using xsltproc) and
1402 epub (using dbtoepub) version from Docbook XML, and the resulting files
1403 are placed in the debian-edu-doc-en binary package.
</p
>
1405 <p
>But English documentation is not enough for us. We want translated
1406 documentation too, and we want to make it easy for translators to
1407 track the English original. For this we use the
1408 <a href=
"http://packages.qa.debian.org/p/poxml.html
">poxml
</a
> package,
1409 which allow us to transform the English Docbook XML file into a
1410 translation file (a .pot file), usable with the normal gettext based
1411 translation tools used by those translating free software. The pot
1412 file is used to create and maintain translation files (several .po
1413 files), which the translations update with the native language
1414 translations of all titles, paragraphs and blocks of text in the
1415 original. The next step is combining the original English Docbook XML
1416 and the translation file (say debian-edu-wheezy-manual.nb.po), to
1417 create a translated Docbook XML file (in this case
1418 debian-edu-wheezy-manual.nb.xml). This translated (or partly
1419 translated, if the translation is not complete) Docbook XML file can
1420 then be used like the original to create a PDF, HTML and epub version
1421 of the documentation.
</p
>
1423 <p
>The translators use different tools to edit the .po files. We
1425 <a href=
"http://www.kde.org/applications/development/lokalize/
">lokalize
</a
>,
1426 while some use emacs and vi, others can use web based editors like
1427 <a href=
"http://pootle.translatehouse.org/
">Poodle
</a
> or
1428 <a href=
"https://www.transifex.com/
">Transifex
</a
>. All we care about
1429 is where the .po file end up, in our git repository. Updated
1430 translations can either be committed directly to git, or submitted as
1431 <a href=
"https://bugs.debian.org/src:debian-edu-doc
">bug reports
1432 against the debian-edu-doc package
</a
>.
</p
>
1434 <p
>One challenge is images, which both might need to be translated (if
1435 they show translated user applications), and are needed in different
1436 formats when creating PDF and HTML versions (epub is a HTML version in
1437 this regard). For this we transform the original PNG images to the
1438 needed density and format during build, and have a way to provide
1439 translated images by storing translated versions in
1440 images/$LANGUAGECODE/. I am a bit unsure about the details here. The
1441 package maintainers know more.
</p
>
1443 <p
>If you wonder what the result look like, we provide
1444 <a href=
"http://maintainer.skolelinux.org/debian-edu-doc/
">the content
1445 of the documentation packages on the web
</a

1468 keep gaining new users. Some weeks ago, a person showed up on IRC,
1469 <a href=
"irc://irc.debian.org/#debian-edu
">#debian-edu
</a
>, with a
1470 wish to contribute, and I managed to get a interview with this great
1471 contributor Roger Marsal to learn more about his background.
</p
>
1473 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
1475 <p
>My name is Roger Marsal, I
'm
27 years old (
1986 generation) and I
1476 live in Barcelona, Spain. I
've got a strong business background and I
1477 work as a patrimony manager and as a real estate agent. Additionally,
1478 I
've co-founded a British based tech company that is nowadays on the
1479 last development phase of a new social networking concept.
</p
>
1481 <p
>I
'm a Linux enthusiast that started its journey with Ubuntu four years
1482 ago and have recently switched to Debian seeking rock solid stability
1483 and as a necessary step to gain expertise.
</p
>
1485 <p
>In a nutshell, I spend my days working and learning as much as I
1486 can to face both my job, entrepreneur project and feed my Linux
1489 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
1490 project?
</strong
></p
>
1492 <p
>I discovered the
<a href=
"http://www.ltsp.org/
">LTSP
</a
> advantages
1493 with
"Ubuntu
12.04 alternate install
" and after a year of use I
1494 started looking for an alternative. Even though I highly value and
1495 respect the Ubuntu project, I thought it was necessary for me to
1496 change to a more robust and stable alternative. As far as I was using
1497 Debian on my personal laptop I thought it would be fine to install
1498 Debian and configure an LTSP server myself. Surprised, I discovered
1499 that the Debian project also supported a kind of Edubuntu equivalent,
1500 and after having some pain I obtained a Debian Edu network up and
1501 running. I just loved it.
</p
>
1503 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
1504 Edu?
</strong
></p
>
1506 <p
>I found a main advantage in that, once you know
"the tips and
1507 tricks
", a new installation just works out of the box. It
's the most
1508 complete alternative I
've found to create an LTSP network. All the
1509 other distributions seems to be made of plastic, Debian Edu seems to
1510 be made of steel.
</p
>
1512 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
1513 Edu?
</strong
></p
>
1515 <p
>I found two main disadvantages.
</p
>
1517 <p
>I
'm not an expert but I
've got notions and I had to spent a considerable
1518 amount of time trying to bring up a standard network topology. I
'm quite
1519 stubborn and I just worked until I did but I
'm sure many people with few
1520 resources (not big schools, but academies for example) would have switched
1521 or dropped.
</p
>
1523 <p
>It
's amazing how such a complex system like Debian Edu has achieved
1524 this out-of-the-box state. Even though tweaking without breaking gets
1525 more difficult, as more factors have to be considered. This can
1526 discourage many people too.
</p
>
1528 <p
><strong
>Which free software do you use daily?
</strong
></p
>
1530 <p
>I use Debian, Firefox, Okular, Inkscape, LibreOffice and
1531 Virtualbox.
</p
>
1534 <p
><strong
>Which strategy do you believe is the right one to use to
1535 get schools to use free software?
</strong
></p
>
1537 <p
>I don
't think there is a need for a particular strategy. The free
1538 attribute in both
"freedom
" and
"no price
" meanings is what will
1539 really bring free software to schools. In my experience I can think of
1540 the
<a href=
"http://www.r-project.org/
">"R
" statistical language
</a
>; a
1541 few years a ago was an extremely nerd tool for university people.
1542 Today it
's being increasingly used to teach statistics at many
1543 different level of studies. I believe free and open software will
1544 increasingly gain popularity, but I
'm sure schools will be one of the
1545 first scenarios where this will happen.

>On larger sites, it is useful to use a dedicated storage server for
1555 storing user home directories and data. The design for handling this
1556 in
<a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>, is
1557 to update the automount rules in LDAP and let the automount daemon on
1558 the clients take care of the rest. I was reminded about the need to
1559 document this better when one of the customers of
1560 <a href=
"http://www.slxdrift.no/
">Skolelinux Drift AS
</a
>, where I am
1561 on the board of directors, asked about how to do this. The steps to
1562 get this working are the following:
</p
>
1566 <li
>Add new storage server in DNS. I use nas-server.intern as the
1567 example host here.
</li
>
1569 <li
>Add automoun LDAP information about this server in LDAP, to allow
1570 all clients to automatically mount it on reqeust.
</li
>
1572 <li
>Add the relevant entries in tjener.intern:/etc/fstab, because
1573 tjener.intern do not use automount to avoid mounting loops.
</li
>
1575 </ol
></p
>
1577 <p
>DNS entries are added in GOsa², and not described here. Follow the
1578 <a href=
"https://wiki.debian.org/DebianEdu/Documentation/Wheezy/GettingStarted
">instructions
1579 in the manual
</a
> (Machine Management with GOsa² in section Getting
1582 <p
>Ensure that the NFS export points on the server are exported to the
1583 relevant subnets or machines:

1592 <p
>Here everything on the backbone network is granted access to the
1593 /storage export. With NFSv3 it is slightly better to limit it to
1594 netgroup membership or single IP addresses to have some limits on the
1595 NFS access.
</p
>
1597 <p
>The next step is to update LDAP. This can not be done using GOsa²,
1598 because it lack a module for automount. Instead, use ldapvi and add
1599 the required LDAP objects using an editor.

1605 <p
>When the editor show up, add the following LDAP objects at the
1606 bottom of the document. The
"/
&" part in the last LDAP object is a
1607 wild card matching everything the nas-server exports, removing the
1608 need to list individual mount points in LDAP.

1631 <p

1655 <p
>I am a
23 year-old student from Germany who has spent half of his
1656 life with open source. In
"real life
", I am, as already mentioned, a
1657 student in the fields of Computer Science, Electrical Engineering,
1658 Information Technologies and Anglistics. Due to my (only partially
1659 voluntary) huge engagement in the open source world, these things are
1660 a bit vacant right now however.
</p
>
1662 <p
>I also have been working as a project teacher at a Gymasnium
1663 (public school) for various years now. I took up that work some time
1664 around
2005 when still attending that school myself and have continued
1665 it until today. I also had been running the (kind of very advanced)
1666 network of that school together with a team of very interested and
1667 talented students in the age of
11 to
15 years, who took the chance to
1668 learn a lot about open source and networking before I left the school
1669 to help building another school
's informational education concept from
1672 <p
>That said, one might see me as a kind of
"glue
" between school kids
1673 and the elderly of teachers as well as between the open source
1674 ecosystem and the (even more complex) educational ecosystem.
</p
>
1676 <p
>When I am not busy with open source or education, I like Geocaching
1677 and cycling.

1679 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
1680 project?
</strong

1682 <p
>I think that happened some time around
2009 when I first attended
1683 <a href=
"http://www.froscon.org
">FrOSCon
</a
> and visited the project
1684 booth. I think I wasn
't too interested back then because I used to
1685 have an attitude of disliking software that does too much stuff on its
1686 own. Maybe I was too inexperienced to realise the upsides of an
1687 "out-of-the-box
" solution ;).
</p
>
1689 <p
>The first time I actively talked to Skolelinux people was at
1690 <a href=
"http://www.openrheinruhr.de
">OpenRheinRuhr
</a
> 2011 when the
1691 BiscuIT project, a home-grewn software used by my school for various
1692 really cool things from timetables and class contact lists to lunch
1693 ordering, student ID card printing and project elections first got to
1694 a stage where it could have been published. I asked the Skolelinux
1695 guys running the booth if the project were interested in it and gave a
1696 small demonstration, but there wasn
't any real feedback and the guys
1697 seemed rather uninterested.
</p
>
1699 <p
>After I left the school where I developed the software, it got
1700 mostly lost, but I am now reimplementing it for my new school. I have
1701 reusability and compatibility in mind, and I hop there will be a new
1702 basis for contributing it to the Skolelinux project ;)!
</p
>
1704 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
1705 Edu?
</strong
></p
>
1707 <p
>The most important advantage seems to be that it
"just
1708 works
". After overcoming some minor (but still very annoying) glitches
1709 in the installer, I got a fully functional, working school network,
1710 without the month-long hassle I experienced when setting all that up
1711 from scratch in earlier years. And above that, it rocked - I didn
't
1712 have any real hardware at hand, because the school was just founded
1713 and has no money whatsoever, so I installed a combined server (main
1714 server, terminal services and workstation) in a VM on my personal
1715 notebook, bridging the LTSP network interface to the ethernet port,
1716 and then PXE-booted the Windows notebooks that were lying around from
1717 it. I could use
8 clients without any performance issues, by using a
1718 tiny little VM on a tiny little notebook. I think that
's enough to say
1719 that it rocks!
</p
>
1721 <p
>Secondly, there are marketing reasons. Life
's bad, and so no
1722 politician will ever permit a setup described as
"Debian, an universal
1723 operating system, with some really cool educational tools
" while they
1724 will be jsut fine with
"Skolelinux, a single-purpose solution for your
1725 school network
", even if both turn out to be the very same thing (yes,
1726 this is unfair towards the Skolelinux project, and must not be taken
1727 too seriously - you get the idea, anyway).

</strong

1749 <p
>First of all, all software I use is free and open. I have abandoned
1750 all non-free software (except for firmware on my darned phone) this
1753 <p
>I run Debian GNU/Linux on all PC systems I use. On that, I mostly
1754 run text tools. I use
1755 <a href=

">mksh
</a
> as shell,
1756 <a href=
"https://www.mirbsd.org/jupp.htm
">jupp
</a
> as very advanced
1757 text editor (I even got the developer to help me write a script/macro
1758 based full-featured student management software with the two),
1759 <a href=
"http://mcabber.com/
">mcabber

> for XMPP and
1760 <a href=
"http://www.irssi.org/
">irssi
</a
> for IRC. For that overly
1761 coloured world called the WWW, I use
1762 <a href=

1763 (Firefox)
</a
>. Oh, and

1766 <p
>However, while I am personally aware of the fact that text tools
1767 are more efficient and powerful than anything else, I also use (or at
1768 least operate) some tools that are suitable to bring open source to
1769 kids. One of these things is
<a href=
"http://jappix.org/
">Jappix
</a
>,
1770 which I already introduced to some kids even before they got aware of
1771 Facebook, making them see for themselves that they do not need
1772 Facebook now ;).
</p
>
1774 <p
><strong
>Which strategy do you believe is the right one to use to
1775 get schools to use free software?
</strong
></p
>
1777 <p
>Well, that
's a two-sided thing. One side is what I believe, and one
1778 side is what I have experienced.
</p
>
1780 <p
>I believe that the right strategy is showing them the benefits. But
1781 that won
't work out as long as the acceptance of free alternatives
1782 grows globally. What I mean is that if all the kids are almost forced
1783 to use Windows, Facebook, Skype, you name it at home, they will not
1784 see why they would want to use alternatives at school. I have seen
1785 students take seat in front of a fully-functional, modern Debian
1786 desktop that could do anything their Windows at home could do, and
1787 they jsut refused to use it because
"Linux sucks
". It is something
1788 that makes the council of our city spend around
600000 € to buy
1789 software - not including hardware, mind you - for operating school
1790 networks, and for installing a system that, as has been proved, does
1791 not work. For those of you readers who are good at maths, have you
1792 already found out how many lives could have been saved with that money
1793 if we had instead used it to bring education to parts of the world
1794 that need it? I have, and found it to be nothing less dramatic than
1795 plain criminal.
</p
>
1797 <p
>That said, the only feasible way appears to be the bottom up
1798 method. We have to bring free software to kids and parents. I have
1799 founded an association named
1800 <a href=
"https://www.teckids.org
">Teckids
</a
> here in Germany that does
1801 just that. We organise several events for kids and adolescents in the
1802 area of free and open source software, for example the
1803 <a href=
"http://kids.froscon.org
">FrogLabs
</a
>, which share staff with
1804 Teckids and are the youth programme of
1805 <a href=
"http://www.froscon.org
">the Free and Open Source Software
1806 Conference (FrOSCon)
</a
>. We do a lot more than most other conferences
1807 - this year, we first offered the FrogLabs as a holiday camp for kids
1808 aged
10 to
16. It was a huge success, with approx.
30 kids taking part
1809 and learning with and about free software through a whole weekend. All
1810 of us had a lot of fun, and the results were really exciting.
</p
>
1812 <p
>Apart from that, we are preparing a campaign that is supposed to bring
1813 the message of free alternatives to stuff kids use every day to them and
1814 their parents, e.g. the use of Jabber / Jappix instead of Facebook and
1815 Skype. To make that possible, we are planning to get together a team of
1816 clever kids who understand very well what their peers need and can bring
1817 it across to them. So we will have a peer-driven network of adolescents
1818 who teach each other and collect feedback from the community of minors.
1819 We then take that feedback and our own experience to work closely with
1820 open source projects, such as Skolelinux or Jappix, at improving their
1821 software in a way that makes it more and more attractive for the target
1822 group. At least I hope that we will have good cooperation with
1823 Skolelinux in the future ;)!
</p
>
1825 <p
>So in conclusion, what I believe is that, if it weren
't for the world
1826 being so bad, it should be very clear to the political decision makers
1827 that the only way to go nowadays is free software for various reasons,
1828 but I have learnt that the only way that seems to work is bottom up.
</p
>
1832 > * Who should be interviewed with this questions in the future?
1834 That
's probably the hardest question of them all, as I do not know the
1835 community. However, I would be willing to do the following:
1837 <li
>Run an interview with a German headteacher who is very open to
1838 free software, and also prefers it, but cannot really use it because
1839 of the decision makers above;
1840 <li
>Run interviews with some kids, both with and without previous
1841 knowledge about free software
1843 If that is wanted, just let me know ;).

1859 his success story with installing Debian Edu at their school. This
1860 time I have been able to get some helpful comments from the creator of
1861 Knoppix, Klaus Knopper, who was involved in a Skolelinux project in
1862 Germany a few years ago.

1868 the university of applied sciences Kaiserslautern / Germany and
1869 freelance Open Source software developer and consultant.
</p

1871 <p

1872 from teaching, I
'm also conducting some more or less experimental
1873 projects like the

1882 project?
</strong
></p

1884 <p
>The credit for this have to go to Kurt Gramlich, who is the German
1885 coordinator for Skolelinux. We were looking for an all-in-one open
1886 source community-supported distribution for schools, and Kurt
1887 introduced us to Skolelinux for this purpose.

1890 Edu?

1893 <li

</li

1895 <li

1897 single company,
</li

1898 <li

</li
>
1902 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
1903 Edu?
</strong
></p
>
1906 <li
>Skolelinux is - as we had to learn - not easily upgradable to
1907 the next version. Opposed to its genuine Debian base, upgrading to
1908 a new version means a full new installation from scratch to get it
1909 working again reliably.
1911 <li
>Skolelinux is based on Debian/stable, and therefore always a
1912 little outdated in terms of program versions compared to Edubuntu or
1913 similar educational Linux distros, which rather use Debian/testing
1916 <li
>Skolelinux has some very self-opinionated and stubborn default
1917 configuration which in my opinion adds unnecessary complexity and is
1918 not always suitable for a schools needs, the preset network
1919 configuration is actually a core definition feature of Skolelinux
1920 and not easy to change, so schools sometimes have to change their
1921 network configuration to make it
"Skolelinux-compatible
".
1923 <li
>Some proposed extensions, which were made available as
1924 contribution, like secure examination mode and lecture material
1925 distribution and collection, were not accepted into the mainline
1926 Skolelinux development and are now not easy to maintain in the
1927 future because of Skolelinux somewhat undeterministic update
1930 <li
>Skolelinux has only a very tiny number of base developers
1931 compared to Debian.
</li
>
1935 <p
>For these reasons and experience from our project, I would now
1936 rather consider using plain Debian for schools next time, until
1937 Skolelinux is more closely integrated into Debian and becomes
1938 upgradeable without reinstallation.
</p

1940 <p
><strong
>Which free software do you use daily?
</strong
></p
>
1942 <p
>GNU/Linux with LXDE desktop, bash for interactive dialog and
1943 programming, texlive for documentation and correspondence,
1944 occasionally LibreOffice for document format conversion. Various
1945 programming languages for teaching.

1947 <p
><strong
>Which strategy do you believe is the right one to use to
1948 get schools to use free software?
</strong

1950 <p
>Strong arguments are
</p

1954 <li
>Knowledge is free, and so should be methods and tools for
1955 teaching and learning.
</li
>
1957 <li
>Students can learn with and use the same software at school, at
1958 home, and at their working place without running into license or
1959 conversion problems.
</li
>
1961 <li
>Closed source or proprietary software hides knowledge rather
1962 than exposing it, and proprietary software vendors try to bind
1963 customers to certain products. But teachers need to teach
1964 science, not products.

>About Debian Edu and Skolelinux
</p
>
2099 <p
>Debian Edu, also known as Skolelinux, is a Linux distribution based
2100 on Debian providing an out-of-the box environment of a completely
2101 configured school network. Immediately after installation a school
2102 server running all services needed for a school network is set up just
2103 waiting for users and machines being added via GOsa², a comfortable
2104 Web-UI. A netbooting environment is prepared using PXE, so after
2105 initial installation of the main server from CD or USB stick all other
2106 machines can be installed via the network. The provided school server
2107 provides LDAP database and Kerberos authentication service,
2108 centralized home directories, DHCP server, web proxy and many other
2109 services. The desktop contains more than
60 educational software
2110 packages and more are available from the Debian archive, and schools
2111 can choose between KDE, Gnome, LXDE and Xfce desktop environment.
</p
>
2113 <p
>This is the seventh test release based on Debian Wheezy. Basically
2114 this is an updated and slightly improved version compared to the
2115 Squeeze release.
</p
>
2117 <p
>Notes for upgrades from Alpha Prereleases
</p
>
2119 <p
>Alpha based installations should reinstall or downgrade the
2120 versions of gosa and libpam-mklocaluser to the ones used in this beta
2121 release. Both alpha and beta0 based installations should reinstall or
2122 deal with gosa.conf manually; there are two options: (
1) Keep
2123 gosa.conf and edit this file as outlined on the mailing list. (
2)
2124 Accept the new version of gosa.conf and replace both contained admin
2125 password placeholders with the password hashes found in the old one
2126 (backup copy!). In both cases all users need to change their password
2127 to make sure a password is set for CIFS access to their home
2128 directory.

2175 versions of gosa and libpam-mklocaluser to the ones used in this beta
2176 release. Both alpha and beta0 based installations should reinstall or
2177 deal with gosa.conf manually; there are two options: (
1) Keep
2178 gosa.conf and edit this file as outlined

"http://lists.debian.org/debian-edu/
2013/
08/msg00127.html
">on
2180 the mailing list
</a

2) Accept the new version of gosa.conf and
2181 replace both contained admin password placeholders with the password
2182 hashes found in the old one (backup copy!). In both cases every user
2183 need to change their their password to make sure a password is set for
2184 CIFS access to their home directory.

2190 <li
>Added ssh askpass packages to default installation, to ensure ssh
2191 work also without a attached tty.
</li

2192 <li
>Add the command-not-found package to the default installation to
2193 make it easier to figure out where to find missing command line
2194 tools. Please note, that the command
'update-command-not-found
'
2195 has to be run as root to actually make it useful (internet access
2196 required).

2462 <li

</li

2463 <li
>Dropped menu-xdg from the KDE desktop option, to drop the Debian
2464 submenu. It was not included with Gnome, LXDE or Xfce, so this
2465 brings KDE in line with the others.
</li

2466 <li
>Dropped xdrawchem, xjig and xsok from our default installation as
2467 they don
't have a desktop menu entry and thus won
't show up in the
2468 menu now that menu-xdg was removed.

>
2486 <li
>Made sure root and user passwords were not left behind in the
2487 debconf database after installation on Main Server installations.
</li
>
2488 <li
>Made Roaming Workstation dynamic setup more robust and added draft
2489 script setup-ad-client to hook a Roaming Workstation up to a
2490 Active Directory server instead of a Debian Edu Main Server.
</li
>
2491 <li
>Update system to install needed firmware packages during

2495 and keymap settings to PXE installation clients.

>In the
<a href=
"http://www.skolelinux.org/
">Debian Edu /
2539 Skolelinux
</a
> project, we include a post-installation test suite,
2540 which check that services are running, working, and return the
2541 expected results. It runs automatically just after the first boot on
2542 test installations (using test ISOs), but not on production
2543 installations (using non-test ISOs). It test that the LDAP service is
2544 operating, Kerberos is responding, DNS is replying, file systems are
2545 online resizable, etc, etc. And it check that the PXE service is
2546 configured, which is the topic of this post.
</p
>
2548 <p
>The last week I
've fixed the DVD and USB stick ISOs for our Debian
2549 Edu Wheezy release. These ISOs are supposed to be able to install a
2550 complete system without any Internet connection, but for that to
2551 happen all the needed packages need to be on them. Thanks to our test
2552 suite, I discovered that we had forgotten to adjust our PXE setup to
2553 cope with the new names and paths used by the netboot d-i packages.
2554 When Internet connectivity was available, the installer fall back to
2555 using wget to fetch d-i boot images, but when offline it require
2556 working packages to get it working. And the packages changed name
2557 from debian-installer-
6.0-netboot-$arch to
2558 debian-installer-
7.0-netboot-$arch, we no longer pulled in the
2559 packages during installation. Without our test suite, I suspect we
2560 would never have discovered this before release. Now it is fixed
2561 right after we got the ISOs operational.
</p
>
2563 <p
>Another by-product of the test suite is that we can ask system
2564 administrators with problems getting Debian Edu to work, to run the
2565 test suite using
<tt
>/usr/sbin/debian-edu-test-install
</tt
> and see if
2566 any errors are detected. This usually pinpoint the subsystem causing
2567 the problem.

><strong
>Who are you, and how do you spend your days?
</strong
></p
>
2594 <p
>I
'm a
25 year old free software enthusiast, living in Romania,
2595 which is also my country of origin. Back in
2009, at a New Year
's Eve
2596 party, I had a very nice
<strike
>beer
</strike
> discussion with a
2597 friend, when we realized we have no organised Debian community in our
2598 country. A few days later, we put together the infrastructure for such
2599 community and even gathered a nice Debian-ish crowd. Since then, I
2600 began my quest as a free software hacker and activist and I am
2601 constantly trying to cover as much ground as possible on that
2604 <p
>A few years ago I founded a small web development company, which
2605 provided me the flexible schedule I needed so much for my
2606 activities. For the last
13 months, I have been the Technical Director
2607 of
<a href=
"http://ceata.org/
">Fundația Ceata
</a
>, which is a free
2608 software activist organisation endorsed by the FSF and the FSFE, and
2609 the only one we have in our country.
</p
>
2611 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
2612 project?
</strong
></p
>
2614 <p
>The idea of participating in the Debian Edu project was a surprise
2615 even to me, since I never used it before I began getting involved in
2616 it. This year I had a great opportunity to deliver a talk on
2617 educational software, and I knew immediately where to look. It was a
2618 love at first sight, since I was previously involved with some of the
2619 technologies the project incorporates, and I rapidly found a lot of
2620 ways to contribute.
</p
>
2622 <p
>My first contributions consisted in translating the installer and
2623 configuration dialogs, then I found some bugs to squash (I still
2624 haven
't fixed them yet though), and I even got my eyes on some other
2625 areas where I can prove myself helpful. Since the appetite for free
2626 software in my country is pretty low, I
'll be happy to be the first
2627 one around here advocating for the project
's adoption in educational
2628 environments, and maybe even get my hands dirty in creating a flavour
2629 for our own needs. I am not used to make very advanced plannings, so
2630 from now on, time will tell what I
'll be doing next, but I think I
2631 have a pretty consistent starting point.
</p
>
2633 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
2634 Edu?
</strong
></p
>
2636 <p
>Not a long time ago, I was in the position of configuring and
2637 maintaining a LDAP server on some Debian derivative, and I must say it
2638 took me a while. A long time ago, I was maintaining a bigger
2639 Samba-powered infrastructure, and I must say I spent quite a lot of
2640 time on it. I have similar stories about many of the services included
2641 with Skolelinux, and the main advantage I see about it is the
2642 out-of-the box availability of them, making it quite competitive when
2643 it comes to managing a school
's network, for example.
</p
>
2645 <p
>Of course, there is more to say about Skolelinux than the
2646 availability of the software included, its flexibility in various
2647 scenarios is something I can
't wait to experiment
"into the wild
" (I
2648 only played with virtual machines so far). And I am sure there is a
2649 lot more I haven
't discovered yet about it, being so new within the
2652 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
2653 Edu?
</strong
></p
>
2655 <p
>As usual, when it comes to Debian Blends, I see as the biggest
2656 disadvantage the lack of a numerous team dedicated to the
2657 project. Every day I see the same names in the changelogs, and I have
2658 a constantly fear of the bus factor in this story. I
'd like to see
2659 Debian Edu advertised more as an entry point into the Debian
2660 ecosystem, especially amongst newcomers and students. IMHO there are a
2661 lot low-hanging fruits in terms of bug squashing, and enough
2662 opportunities to get the feeling of the Debian Project
's dynamics. Not
2663 to mention it
's a very fun blend to work on!
</p
>
2665 <p
>Derived from the previous statement, is the delay in catching up
2666 with the main Debian release and documentation. This is common though
2667 to all blends and derivatives, but it
's an issue we can all work
2670 <p
><strong
>Which free software do you use daily?
</strong
></p
>
2672 <p
>I can hardly imagine myself spending a day without Vim, since my
2673 daily routine covers writing code and hacking configuration files. I
2674 am a fan of the Awesome window manager (but I also like the
2675 Enlightenment project a lot!),
2676 <a href=
"http://www.claws-mail.org/

2677 use and very configurable behaviour. Recently I fell in love with
2678 <a href=
"https://launchpad.net/redshift

</a

2679 get through the night without headaches. Of course, there is much more
2680 stuff in this bag, but I
'll need a blog on my own for doing this!

2682 <p
><strong
>Which strategy do you believe is the right one to use to
2683 get schools to use free software?
</strong

2685 <p
>Well, on this field, I cannot do much more than experiment right
2686 now. So, being far from having a recipe for success, I can only assume
2691 <li
>schools would like to get rid of proprietary software
</li
>
2693 <li
>students will love the openness of the system, and will want to
2694 experiment with it - maybe we need to harvest the native curiosity
2695 of teenagers more?
</li
>
2697 <li
>there is no
"right one
" when it comes to strategies, but it would
2698 be useful to have some success stories published somewhere, so
2699 other can get some inspiration from them (I know I
'd promote
2702 <li
>more active promotion - talks, conferences, even small school
2703 lectures can do magical things if they encounter at least one
2704 person interested. Who knows who that person might be? ;-)
</li
>
2708 <p
>I also see some problems in getting Skolelinux into schools; for
2709 example, in our country we have a great deal of corruption issues, so
2710 it might be hard(er) to fight against proprietary solutions. Also,
2711 people who relied on commercial software for all their lives, would be
2712 very hard to convert against their will.

'm involved in too many things. As I
'm
2732 getting older I
'm learning how to focus a bit more :)

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

2738 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
2739 project?
</strong
></p
>
2741 <p
>I
've been somewhat familiar with the project before, but I think my
2742 first direct exposure to the project was when I met Petter
2743 [Reinholdtsen] and Knut [Yrvin] at the Edubuntu summit in
2005 in
2744 London. They provided great feedback that helped the bootstrapping of
2745 Edubuntu. Back then Edubuntu (and even Ubuntu) was still very new and
2746 it was great getting input from people who have been around longer. I
2747 was also still very excitable and said yes to everything and to this
2748 day I have a big todo list backlog that I
'm catching up with. I think
2749 over the years the relationship between Edubuntu and Debian-Edu has
2750 been gradually improving, although I think there
's a lot that we could
2751 still improve on in terms of working together on packages. I
'm sure
2752 we
'll get there one day.
</p
>
2754 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
2755 Edu?
</strong
></p
>
2757 <p
>Debian itself already has so many advantages. I could go on about
2758 it for pages, but in essence I love that it
's a very honest project
2759 that puts its users first with no hidden agendas and also produces
2760 very high quality work.
</p
>
2762 <p
>I think the advantage of Debian Edu is that it makes many common
2763 set-up tasks simpler so that administrators can get up and running
2764 with a lot less effort and frustration. At the same time I think it
2765 helps to standardise installations in schools so that it
's easier for
2766 community members and commercial suppliers to support.

><strong
>What do you see as the disadvantages of Skolelinux / Debian
2769 Edu?
</strong

2771 <p
>I had to re-type this one a few times because I
'm trying to
2772 separate
"disadvantages
" from
"areas that need improvement
" (which is
2773 what I originally rambled on about)
</p
>
2775 <p
>The biggest disadvantage I can think of is lack of manpower. The
2776 project could do so much more if there were more good contributors. I
2777 think some of the problems are external too. Free software and free
2778 content in education is a no-brainer but it takes some time to catch
2779 on. When you
've been working with the same proprietary eco-system for
2780 years and have gotten used to it, it can be hard to adjust to some
2781 concepts in the free software world. It would be nice if there were
2782 more Debian Edu consultants across the world. I
'd love to be one
2783 myself but I
'm already so over-committed that it
's just not possible
2784 currently.
</p
>
2786 <p
>I think the best short-term solution to that large-scale problem is
2787 for schools to be pro-active and share their experiences and grow
2788 their skills in-house. I
'm often saddened to see how much money
2789 educational institutions spend on
3rd party solutions that they don
't
2790 have access to after the service has ended and they could
've gotten so
2791 much more value otherwise by being more self-sustainable and
2792 autonomous.
</p
>
2794 <p
><strong
>Which free software do you use daily?
</strong
></p
>
2796 <p
>My main laptop dual-boots between Debian and Windows
7. I was
2797 Windows free for years but started dual-booting again last year for
2798 some games which help me focus and relax (Starcraft II in
2799 particular). Gaming support on Linux is improving in leaps and bounds
2800 so I suppose I
'll soon be able to regain that disk space :)
</p
>
2802 <p
>Besides that I rely on Icedove, Chromium, Terminator, Byobu, irssi,
2803 git, Tomboy, KVM, VLC and LibreOffice. Recently I
've been torn on
2804 which desktop environment I like and I
'm taking some refuge in Xfce
2805 while I figure that out. I like tools that keep things simple. I enjoy
2806 Python and shell scripting. I went to an Arduino workshop recently and
2807 it was awesome seeing how easy and simple the IDE software was to get
2808 up and running in Debian compared to the users running Windows and OS
2811 <p

2812 using Norton Commander in the early

2819 <p

2820 many cases it
's appropriate for schools to use non-free systems and I
2821 don
't think that there
's any particular moral or ethical problem with
2824 <p
>I do think though that free software can already solve so so many
2825 problems in educational institutions and it
's just a shame not taking
2826 advantage of that.
</p
>
2828 <p
>I also think that some curricula need serious review. For example,
2829 some areas of the world rely heavily on very specific versions of MS
2830 Office, teaching students to parrot menu items instead of learning the
2831 general concepts. I think that
's very unproductive because firstly, MS
2832 Office
's interface changes drastically every few years and on top of
2833 that it also locks in a generation to a product that might not be the
2834 best solution for them.
</p

2836 <p
>To answer your question, I believe that the right strategy is to
2837 educate and inform, giving someone the information they require to
2838 make a decision that would work for them.

2860 out-of-the box environment of a completely configured school
2861 network. Immediately after installation a school server running all
2862 services needed for a school network is set up just waiting for users
2863 and machines being added via GOsa², a comfortable Web-UI. A netbooting
2864 environment is prepared using PXE, so after initial installation of
2865 the main server from CD, DVD or USB stick all other machines can be
2866 installed via the network. The provided school server provides LDAP
2867 database and Kerberos authentication service, centralized home
2868 directories, DHCP server, web proxy and many other services. The

3002 interview last November. But the developers and translators are still
3003 pulling along to get the Wheezy based release out the door, and this
3004 time I managed to get an interview from one of the French translators
3005 in the project, Cédric Boutillier.

3009 <p
>I am
34 year old. I live near Paris, France. I am an assistant
3010 professor in probability theory. I spend my daytime teaching
3011 mathematics at the university and doing fundamental research in
3012 probability in connexion with combinatorics and statistical physics.
</p
>
3014 <p
>I have been involved in the Debian project for a couple of years
3015 and became Debian Developer a few months ago. I am working on Ruby
3016 packaging, publicity and translation.

3018 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
3019 project?
</strong
></p
>
3021 <p
>I came to the Debian Edu project after a call for translation of
3022 <a href=
"http://wiki.debian.org/DebianEdu/Documentation/Manuals

3023 Debian Edu manual

3024 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
3028 virtual machine when I was preparing localised version of some screen
3029 shots for the manual. I was amazed to see it worked out of the box and
3030 how comprehensive the list of software installed by default was.
</p
>
3032 <p
>What amazed me was the complete network infrastructure directly
3033 ready to use, which can and the nice administration interface provided
3034 by
<a href=
"https://oss.gonicus.de/labs/gosa/
">GOsa²
</a
>. What pleased
3035 me also was the fact that among the software installed by default,
3036 there were many
"traditional
" educative software to learn languages,
3037 to count, to program... but also software to develop creativity and
3038 artistic skills with music (
<a href=
"http://ardour.org/
">Ardour
</a
>,
3039 <a href=
"http://audacity.sourceforge.net/
">Audacity
</a

3040 movies/animation (I was especially thinking of
3041 <a href=
"http://linuxstopmotion.sourceforge.net/
">Stopmotion
</a

3045 Unfortunately, I don
't much time to get more involved in this
3046 beautiful project.
</p
>
3048 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
3049 Edu?
</strong
></p
>
3051 <p
>For me, the main advantages of Skolelinux/Debian Edu are its
3052 community of experts and its precise documentation, as well as the
3053 fact that it provides a solution ready to use.
</p
>
3055 <p
>I would add also the fact that it is based on the rock solid Debian
3056 distribution, which ensures stability and provides a huge collection
3057 of educational free software.
</p
>
3059 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
3060 Edu?
</strong
></p
>
3062 <p
>Maybe the lack of manpower to do lobbying on the
3063 project. Sometimes, people who need to take decisions concerning IT do
3064 not have all the elements to evaluate properly free software
3065 solutions. The fact that support by a company may be difficult to find
3066 is probably a problem if the school does not have IT personnel.
</p
>
3068 <p
>One can find support from a company by looking at
3069 <a href=
"http://wiki.debian.org/DebianEdu/Help/ProfessionalHelp
">the
3070 wiki dokumentation
</a
>, where some countries already have a number of
3071 companies providing support for Debian Edu, like Germany or
3072 Norway. This list is easy to find readily from the manual. However,
3073 for other countries, like France, the list is empty. I guess that
3074 consultants proposing support for Debian would be able to provide some
3075 support for Debian Edu as well.
</p
>
3077 <p
><strong
>Which free software do you use daily?
</strong
></p
>
3079 <p
>I am using the KDE Plasma Desktop. But the pieces of software I use
3080 most runs in a terminal: Mutt and OfflineIMAP for emails, latex for
3081 scientific documents, mpd for music. VIM is my editor of choice. I am
3082 also using the mathematical software
3083 <a href=
"http://www.scilab.org/en/scilab/about
">Scilab
</a
> and
3084 <a href=
"http://www.sagemath.org/index.html
">Sage

3088 using the free software in Debian to teach mathematics and
3089 statistics?
</strong

3091 <p
>I do not have any
"nice
" recommendations for statistics. At our
3092 university, we use both
<a href=
"http://www.r-project.org/

3093 Scilab to teach statistics and probabilistic simulations. For
3094 geometry, there are nice programs:

3284 kan få til med en datamaskin til NOK

1700,- med
3285 skjerm, tastatur og mus) når det brukes i Skolelinux. Jeg spurte han
3286 om et intervju.

3288 <p
><strong
>Hvem er du, og hva driver du med til daglig?

3290 <p
>Jeg heter Nirosan Thiyagalingam. Jeg er
24 år og studerer
3291 dataingeniør studiet ved Høgskolen i Sør Trøndelag. Interessen for
3292 data har siden ung alder vært tilstede og jeg har i tillegg alltid
3293 vært glad i å lære nye ting. Med teknologi som endres svært hurtig er
3294 det alltid noe nytt å lære. Noe som igjen har gjort det svært
3295 interessant å følge med på utviklingen. Jeg valgte dataingeniør
3296 studiet grunnet ønske om å lære enda mer om programmering og utvikling
3297 av store systemer.
</p

3299 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
3301 <p
>Skolelinux prosjektet hørte jeg først om i media. Men det var først
3302 når jeg skulle velge bacheloroppgave at jeg fattet mer interesse for
3303 prosjektet. Et enkelt søk på nettet førte meg til skolelinux sine
3304 hjemmesider. Informasjonen jeg fant der gjorde meg enda nysgjerrig og
3305 jeg valgte derfor en oppgave som gikk ut på å få en
3306 <a href=
"http://www.raspberrypi.org
">Raspberry PI
</a
>. Altså en
3307 ultra-billig datamaskin til å kjøre Debian Edu på lik linje med
3308 vanlige datamaskiner. I løpet av prosjektet ble det gjort mye
3309 forskning på nettet. Det var mye jeg måtte forstå rundt hvordan
3310 operativsystemet Linux fungerte før jeg kunne angripe
3311 problemet. Prøvde først å finne ut hvordan man kunne transformere en
3312 vanlig installasjon av Skolelinux til Raspberry PI, men dette var
3313 altfor vanskelig å jeg endte opp med mer spørsmål enn svar. Det ble
3314 videre opprettet kontakt med Skolelinux utviklere på IRC der jeg fikk
3315 diskutert hvilken retning jeg burde gå for å få til en fullverdig
3316 løsning. Det ble bestemt at jeg skulle gå for å først installere
3317 <a href=
"http://www.raspbian.org/
">Raspian
</a
>. Dette er et
3318 operativsystem basert på Debian spesiallaget for Raspberry Pi sin
3319 maskinvare. Nå som Debian var installert på datamaskinen gjenstod det
3320 å installere de nødvendige Skolelinux pakkene for å få til et
3321 fullverdig system. Disse pakkene ble installert manuelt i første
3322 omgang, men ble senere installert automatisk via et script som Petter
3323 Reinholdtsen laget. Dette scriptet er så enkel å bruke at man er i
3324 gang med installasjonen i løpet av bare
5 minutter. Ikke nok med det,
3325 alt skjer helt automatisk. Alt i alt er jeg veldig fornøyd med
3326 resultatet av installasjonsprosessen. Raspberry Pi er en veldig svak
3327 maskin og det merkes godt når man har installert Skolelinux på
3328 den. Video og
3D-rendering fungerer utrolig dårlig, men nettsurfing og
3329 kontorprogrammer fungerer godt. Det kan derfor konkluderes med at
3330 datamaskinen er egnet for enkle oppgaver.
3332 <p
>Jeg syns det er viktig påpeke at dette kun er startfasen av en slik
3333 løsning. På markedet finnes det nå maskiner som har bedre hardware enn
3334 Raspberry Pi. Det er store muligheter for at man kan klare å
3335 installere Skolelinux på disse også, og da forsvinner nok mest
3336 sannsynlig ytelsesproblemene med Video og
3D rendering også.
</p
>
3338 <p
>Det ble også prøvd med en løsning som gjorde at Raspberry Pi
3339 fungerte som en tynnklient. Denne løsningen hadde langt bedre ytelse
3340 med tanke på hastighet og brukeropplevelse. Men også her var video og
3341 3D rendering dårlig. Det ble brukt en liten Linux distribusjon kalt

3348 fordel, men at det er så mange som er med på å utvikle det og
3349 vedlikeholde det er en enda større fordel. Allerede før jeg startet
3350 med prosjektet så jeg mange fordeler, og når jeg nærmet meg sluttfasen
3351 så jeg langt flere. At prosjektet skulle inneha en så høy kvalitet
3352 hadde jeg aldri trodd. En vanlig Skolelinux installasjon har de
3353 nødvendige programmene og funksjonen som både små og store skoler i
3354 tillegg til organisasjoner kan klare seg med. At prosjektet tilbyr en
3355 så komplett løsning er en kjempefordel. Installasjonen er knirkefri
3356 og det er svært enkelt å installere og komme i gang.

3358 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p

3360 <p
>Ulempene jeg ser med prosjektet er ryddigheten av websidene. Selv
3361 om websidene er enkle og konsise er det allikevel ikke appellerende i
3362 like stor grad som for eksempel
3363 <a href=
"http://www.ubuntu.com
">Ubuntu
</a
> sine sider. Deres side
3364 tilbyr, i tillegg til godt design og presentasjon, en nettbasert
3365 emulator av deres operativsystem. Dette er en stor fordel slik jeg ser
3366 det. Bortsett fra dette ser jeg absolutt ingen ulemper med
3367 Skolelinux-prosjektet.

3369 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong

3371 <p
>Til daglig er jeg en flittig bruker av det åpne media
3372 sentersystemet
<a href=
"http://xbmc.org/
">XBMC
</a
>. Det enorme
3373 samfunnet rundt dette prosjektet har gjort dette til et program som
3374 dekker alles behov. Man kan tilpasse det akkurat slik man vil både med
3375 tanke på utseende og funksjoner ved installere plug-ins eller
3378 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
3379 skoler til å ta i bruk fri programvare?
</strong
></p
>
3381 <p
>Strategien som burde brukes sett fra mine øyne er
3382 markedsføring. Jeg er sikker på at om flere skoler fikk et lite innsyn
3383 i hvor bra Skolelinux er så ville de ikke nølt med å gå over fra noe
3384 annet som koster de store summer. At skolelinux til de grader tilbyr
3385 en så komplett løsning bure komme frem. Enten via reklamekampanjer
3386 eller ved å sende ut folk til skoler for så å la skolenettverk
3387 ansvarlige få teste ut hvordan Skolelinux fungerer i praksis. Om det
3388 i tillegg ble utviklet gode websider og en emulator for å la brukere
3389 prøve operativsystemet ville nok dette ha styrket inntrykket
3390 betraktelig.

3430 according to the profile specified in the config above,
3431 overriding some of the Debian automation machinery.

>Run debian-edu-cfengine-D installation to configure everything

3488 waiting for users and machines being added via GOsa², a comfortable
3489 Web-UI. A netbooting environment is prepared using PXE, so after
3490 initial installation of the main server from CD, DVD or USB stick all
3491 other machines can be installed via the network.

9 millioner

3589 at læreplanens krav oppfylles uten problemer ved bruk av Skolelinux.
3590 Jeg anbefaler alle å lese de
10 sidene med gode argumenter for å kutte
3591 unødige utgifter på IT i skoleverket. :)

3777 the video show a walk-through of of the menu content, demonstration of
3778 a few programs and his view of our distribution.
</p

3780 <p
>There is also some really nice quotes (transcribed by me, might
3781 have heard wrong). While looking thought the Graphics menu:
</p
>
3784 "Basically everything you ever need in a school environment.
"
3787 <p
>And as a general evaluation of the entire distribution:
</p
>
3790 "So, yeah, a bit bloated. It kept all the Debian stuff in there, just
3791 to keep it nice and GNU. So, I do not want to go on about it, but
3792 lets give it
7 out of
10. I am not going to use it. That is because
3793 I am not deploying a school network. There may be some mythical
3794 feature to help you deploy Skolelinux on a school network.
"
3797 <p
>To bad he did not test the server profile, and discovered the PXE
3798 installation option. It make it possible to install only the main
3799 server from CD, and the rest of the machines via the net, and might be
3800 considered the mythical feature he talk about. :)
</p
>
3802 <p
>While looking through the menus, there is also this funny comment
3803 about the part of the K menu generated from the Debian menu subsystem:
3806 "[The K menu] have a special Debian section for software that no-one
3807 is going to look at, because it contain lots of junky stuff that you
3808 actually don
't need in the education distribution, but have just been
3809 included because it isn
't stripped out for some reason.
"
3812 <p
>I guess it is yet another argument for merging the Debian menu and
3813 Gnome/KDE desktop menu entries into
3814 <a href=
"http://wiki.debian.org/Proposals/DebianMenuUsingDesktopEntries
">one
3815 consistent menu system

>Etter en lang pause og travle uker har jeg endelig klart å få
3928 samlet et nytt intervju med en av folkene i
3929 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet.
3930 Denne gang er det Helge Tore Høyland, en mangeårig bidragsyter på
3931 epostlistene og ellers i prosjektet.
</p
>
3933 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
3935 <p
>Eg er IT-konsulent/teknikker hjå eit firma i Steinkjer med navn
3936 <a href=
"http://unoit.no/
">Uno IT
</a
>. Uno IT er eit lite firma som
3937 drifter nettverk og maskiner for små og mellomstore firma
3938 Steinkjer-området. Per dags dato er me
2 ansatte. Min faglege bakgrunn
3939 er Fagbrev som it-teknikker, samt nokre fag innen nettverk- og
3940 server-drift frå HiST og NTNU. Dagleg arbeid består i oppsett av nye
3941 maskiner og hjelp til sluttbrukere, samt oppsett og vedlikehold av eit
3942 vidt spekter av fagsystemer ute hjå kunder. Erfaring med Skolelinux
3943 har eg hatt i forbindelse med drifting av
3944 <a href=
"http://www.bjorkly.no/
">Bjørkly skule
</a
>, ein privat
3945 grunnskule i Namsos-området. I dag har skulen
65 elever,
15 lærere,
1
3946 hovedserver og ca
60 klienter som kjører halvtjukt. Eg har bygd og
3947 driftet systemet sidan summaren
2006.
</p
>
3949 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
3951 <p
>Eg kom i kontakt med Skolelinux-prosjektet via ein artikkel i eit
3952 fagblad, som eg ikkje lenger hugsar namnet på. I og med at eg allereie
3953 hadde pusla med nettverk for ein annan skule, fatta eg straks
3954 interesse for prosjektet.
</p
>
3956 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
3958 <p
>Fordelane med Skolelinux er sentralisert administrasjon og svært
3959 mange gode verktøy «ut av boksen». Veldig kjekt å kunne drifte
60
3960 klientar med berre å «bry» seg med ein server. Levetid for systemets
3961 hardware er og ein veldig fin effekt. I tillegg kjem fordelar som økt
3962 sikkerhet og mindre lisenskostnader. Etter min erfaring er det og
3963 mykje mindre driftskostnader med eit slikt system enn konkurrerande
3964 system, pga enkelhet med sentralisert administrasjon. På grunn av at
3965 Skolelinux er basert på Debian er det òg svært stabilt.
</p
>
3967 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
3969 <p
>Ulemper er mangel på vilje til å følge standarer ute i markedet,
3970 som fører til mangel på støtte til nokre mykje brukte ting. Flash og
3971 Java er typiske eksempel. Sidan Debian satsar på stabilitet framfor å
3972 ha nyeste pakke av eit program, kan ein i nokre tilfeller kome borti
3973 at program vert «for gamle». Det er spesielt nettlesaren som er
3974 utsett. Mangel på vilje til å utvikle pedagogisk programvare, i Noreg,
3975 for «alle» platformer fører òg til noko hovudbry.
</p
>
3977 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
3979 <p
>Til dagleg bruker eg svært mange forskjellige «fri programvare»
3980 program. Firefox, Thunderbird, Freecommander, ImgBurn, Clonezilla,
3981 OCS inventory, Icinga, Skolelinux, SystemRescueCD og mykje meir.
</p
>
3983 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
3984 skoler til å ta i bruk fri programvare?
</strong
></p
>
3986 <p
>Strategisk må ein fokusere på at sluttbruker eigentleg ikkje er så
3987 fokusert på at det er fri programvare men at det skal «berre fungere».
3988 Gjer det enkelt å bruker og ikkje minst å administrere. For Skolelinux
3989 sin del må ein få eit betre fokus på overganger. Utbytting av servere
3990 må gå meir automatisk, import og eksport av brukerbase og maskinbase
3991 med meir må kunne gå enkelt og oppgradering til neste versjon må bli
3992 mykje meir automatisk og gjennomtesta. Ein må unngå at ein må sette
3993 opp frå start når ein byter ut ein server eller oppgraderer til neste
3994 versjon. For å få Skolelinux til å bli eit betre alternativ for skular
3995 må ein ha fokus på nettlesaren. Denne må bli «up to date» og støtte
3996 dei protokollar og tillegg som vert brukt av forlag med meir. Etter
3997 kvart som meir og meir blir flytta ut i «skya» vert dette viktigare og
3998 viktigare. Ein kunne ynskje og jobbe for at forlag med fleire tar i
3999 bruk opne standarer, men inntil det skjer, må systemet kunne brukast
4000 mot desse fagsystema.
</p
>
4002 <p
>For meg har prosjektet med Skolelinux vore ein svært artig og
4003 lærerik prosess. Miljøet rundt er ikkje enormt stort, dog stort nok,
4004 men det er svært hjelpevillig og engasjert.

4018 present. As the Debian Edu / Skolelinux project is very short on
4019 funding these days, and thus lack the money to do regular developer
4020 gatherings, this donation was most welcome. One developer gathering
4021 cost around NOK
15&nbsp;
000,-, so we need quite a lot more to keep the
4022 development pace we want. Thus, I hope their example this year is
4023 followed by many others. :)

4041 interesting, as I am involved with several organizations where
4042 accounting is an issue, and I have not really become too friendly with
4043 the different web based systems we use. I find it hard to find what I
4044 look for in the menus and even harder try to get sensible data out of
4045 the systems. Ledger seem different. The accounting data is kept in
4046 text files that can be stored in a version control system, and there
4048 are at least
<a href=

4049 different implementations

4099 if you know about someone I should interview, Please send me an email.
4100 After asking for many months, I finally managed to lure another one of
4101 the people behind the German

">IT-Zukunft Schule

4103 project out from maternity leave to conduct an interview. Give a warm
4104 welcome to Angela Fuß. :)
</p
>
4106 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
4108 <p
>I am a
39-year-old woman living in the very north of Germany near
4109 Denmark. I live in a patchwork family with
"my man
" Mike Gabriel, my
4110 two daughters, Mikes daughter and Mikes and my rather newborn son.
4112 <p
>At the moment - because of our little baby - I am spending most of
4113 the day by being a caring and organising mom for all the kids.
4114 Besides that I am really involved into and occupied with several inner
4115 growth processes: New born souls always bring the whole familiar
4116 system into movement and that needs time and focus ;-). We are also
4117 in the middle of buying a house and moving to it.
</p
>
4119 <p
>In
2013 I will work again in my job in a German foundation for
4120 nature conservation. I am doing public relation work there. Besides
4121 that - and that is the connection to Skolelinux / Debian Edu - I am
4122 working in our own school project
"IT-Zukunft Schule
" in North
4123 Germany. I am responsible for the quality assurance, the customer
4124 relationship management and the communication processes in the
4127 <p
>Since
2001 I constantly have been training myself in communication
4128 and leadership. Besides that I am a forester, a landscaping gardener
4129 and a yoga teacher.
</p
>
4131 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
4132 project?
</strong
></p
>
4134 <p
>I fell in love with Mike ;-).
</p
>
4136 <p
>Very soon after getting to know him I was completely enrolled into
4137 Free Software. At this time Mike did IT-services for one newly
4138 founded school in Kiel. Other schools in Kiel needed concepts for
4139 their IT environment. Often when Mike came home from working at the
4140 newly founded school I found myself listening to his complaints about
4141 several points where the communication with the schools head or the
4142 teachers did not work. So we were clear that he would not work for
4143 one more school if we did not set up a structure for communication
4144 between him, the schools head, the teachers, the students and the
4147 <p
>Together with our friend and hardware supplier Andreas Buchholz we
4148 started to get an overview of free software solutions suitable for
4149 schools. One day before Christmas
2010 Mike and I had a date with Kurt
4150 Gramlich in Gütersloh. As Kurt and I are really interested in building
4151 networks of people and in being in communication we dived into
4152 Skolelinux and brought it to the first grammar schools in Northern

</p
>
4159 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
4160 Edu?
</strong
></p
>
4162 <p
>First I have to say: I cannot answer this question technically. My
4163 answer comes rather from a social point of view.
</p
>
4165 <p
>The biggest advantage of Skolelinux / Debian Edu I see is the large
4166 and strong international community of Debian Developers in the
4167 background which is very alive and connected over mailinglists, blogs
4168 and meetings. My constant feeling for the Debian Community is: If
4169 something does not work they will somehow fix it. All is well
4170 ;-). This is of course a user experience. What I also get as a big
4171 advantage of Skolelinux / Debian Edu is that everybody who uses it and
4172 works with it can also contribute to it - that includes students,
4173 teachers, parents...
</p
>
4175 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
4176 Edu?
</strong
></p
>
4178 <p
>I will answer this question relating to the internal structure of
4179 Skolelinux / Debian Edu.
</p
>
4181 <p
>What I see as a major disadvantage is that there is a gap between
4182 the group of developers for Debian Edu and the people who make the
4183 marketing, that means the people that bring Skolelinux to the
4184 schools. There is a lack of communication between these two groups and
4185 I think that does not really work for Skolelinux / Debian Edu.
</p
>
4187 <p
>Further I appreciate that Skolelinux / Debian Edu is known as a
4188 do-ocracy. Nevertheless I keep asking myself if at some points a
4189 democracy or some kind of hierarchical project structure would be good
4190 and helpful. I am also missing some kind of contact between the
4191 Skolelinux / Debian Edu communities in Europe or on an international
4192 level. I think it would be good if there was more sharing between the
4193 different countries using Skolelinux / Debian Edu.
</p
>
4195 <p
><strong
>Which free software do you use daily?
</strong
></p
>
4197 <p
>On my laptop I am still using an Ubuntu
10.04 with a Gnome Desktop
4198 on. As applications I use Openoffice.org, Gedit, Firefox, Pidgin,
4199 LaTeX and GnuCash. For mails I am using Horde. And I am really fond of
4200 my N900 running with Maemo.
</p
>
4202 <p
><strong
>Which strategy do you believe is the right one to use to
4203 get schools to use free software?
</strong
></p
>
4205 <p
>I am really convinced that in our school project
"IT-Zukunft
4206 Schule
" we have developed (and keep developing) a great way to get
4207 schools to use Free Software. We have written a detailed concept for
4208 that so I cannot explain the whole thing here. But in a nutshell the
4209 strategy has three crucial pillars:
</p
>
4213 <li
>We really take time to get what sort of stories, questions and
4214 concerns the schools head and the teachers have about using different
4215 kinds of IT and we take time to enrol them into Free Software.
</li
>
4217 <li
>Our solution for schools is never just technical. In the centre
4218 are always the people who are going to use the software. From the very
4219 beginning of the planning for a school, we tell the schools head that
4220 they are paying us not only for a technical solution for their school,
4221 they also pay us for leading all the communication processes
4222 needed. If they do not want that, we are not working with them because
4223 we cannot give a guarantee for the quality of our work then.
</li
>
4225 <li
>Another focus lies in the training of teachers and students in
4226 co-administrating the IT-System at their school. They start getting in
4227 contact with the Skolelinux / Debian Edu community and they get the
4228 offer to become more and more independent from us.

</p

4251 <p
>I sommer (
2012-
07-
23) hadde Fremover et oppslag om at Narvik
4252 kommune hadde spart mellom
10 og
20 millioner kroner de siste årene på
4253 å bruke Skolelinux på sine skoler. Harstad har også tatt i bruk
4254 Skolelinux på alle sine skoler. Som tidligere Ballangsværing gledet
4255 det meg stort å se at skoleløsningen vi har utviklet siden
2001 tas i
4256 bruk i området der jeg vokste opp, og dermed bidrar til en bedre og
4257 billigere skolehverdag.
</p
>
4259 <p
>Skolelinux er en komplett IT-løsning for elevnettverket på en
4260 skole, med både nettverkstjenester og løsning for elevmaskiner med
4261 pedagogisk programvare, som tillater en å øke levetiden på en
4262 datamaskin i skolen med mange år. En undersøkelse publisert i mars
4263 2012 viste at de
56 norske skolene som har offentliggjort at de bruker
4264 Skolelinux eller annen Linuxutgave hadde
36% større PC-tetthet enn
4265 landsgjennomsnittet, når en ser på tall rapportert til Grunnskolens
4266 Informasjonssystem. I følge Paul Reidar Løsnesløkken, IKT-konsulent i
4267 Nord-Odal, fungerer datamaskiner godt til de er
8 til
10 år gamle.
</p
>
4269 <p
>I høst (
2012-
09-
29) fortalte Fremover hvordan Ballangen kommune har
4270 opparbeidet seg
20 millioner i underskudd og nok havner på Robek-lista
4271 fra nyttår. Kanskje Ballangen også burde ta i bruk Skolelinux for å
4272 spare penger? Hvis kommunen mangler kompetanse lokalt på Linux finnes
4273 det kommersielle selskaper som tilbyr driftstjenester rundt
4274 Skolelinux, og jeg bør vel avsløre at jeg selv er involvert i et av
4275 dem, Skolelinux Drift AS. Kommunen kan dermed få hjelp hvis de ikke
4276 ønsker å bygge opp egen kompetanse.

4482 <p
>Many. First of all there is a strong and living community that is
4483 very generous for help and hints. Chat help is crucial, together with
4484 the mailing list. Second. With Skolelinux you get an already well
4485 engineered platform and you don
't have to start to build up your PDC
4486 and your clients from GNU/scratch; I
've already done this once and I
4487 can tell it, it is hard. Third, since Skolelinux is a standard
4488 platform, it is way easier to educate other IT people and even if the
4489 head IT is sick another one could pick up the task without too much

4496 flexible at client level. Debian stable is rocky and desirable, but
4497 there are many reasons that force for another choice. For example the
4498 need of new drivers for new PC, or the need for a specific OS for some
4499 devices that have specific software packages for another specific

"Narvik kommune bruker gratisprogram i
4552 skolen - Har spart millioner
", forteller om hvordan bruken av
4553 Skolelinux er en stor suksess i Narvik siden det ble tatt i bruk i
4554 2004. Her er noen fine sitater:
</p
>
4557 "- Skolelinux har spart kommunen for store pengesummer, millionbeløp,
4558 som de heller kan bruke på andre ting, sier IKT-konsulent Viggo
4562 <p
>Avisen forteller at de har fått tilgang til beregninger som viser
4563 at Narvik kommune har spart noe mellom
10 og
20 millioner kroner de
4564 siste
8 årene på å bruke Skolelinux, og fortsetter:
</p
>
4568 "Regnestykket tar høyde for sparte kostnader til lisenser som medfølger
4569 de alternative operativsystemene, lavere driftskostnader og lengre
4570 levetid på datautstyret. Totalt har Narvikskolen en maskinpark på
4571 1600 maskiner fordelt på de
11 skolene fra Skjomen i sør til Bjerkvik
4576 <p
>Viggo Fedreheim sier dette om hvor noe av gevinsten kommer fra:
</p
>
4579 "- Vi kan gjenbruke gamle maskiner i skolen som er for dårlig andre
4580 steder i kommunen der de ikke bruker Skolelinux. Levetiden på en
4581 datamaskin blir
3-
5 år lenger med Skolelinux. Vi kaller det for
4582 grønn IT, miljøvennlig IT.
"
4585 <p
>Her er det mulighet for flere kommuner å få et godt IT-system på
4586 skolene, hvis de er villige til å forsøke. De som ikke har kompetanse

12 years at
4663 the same school as
50% IT-manager and

4664 background is fil.kand in history and religious beliefs, an exam as a
4665 "folkhighschool

4666 Norwegian I believe it
's called

4668 just like to study how humans and technology interact and that is my
4669 perspective when working with IT.
</p

4671 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4672 project?
</strong
></p
>
4674 I have followed the Skolelinux project for quite some time by
4675 now. Earlier I tested out the K12-LTSP project, which we used for some
4676 time, but I really like the idea of having a distribution aimed to be
4677 a complete solution for schools with necessary tools integrated. When
4678 K12-LTSP abandoned that idea some years ago, I started to look more
4679 seriously into Skolelinux instead.
4681 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4682 Edu?
</strong
></p
>
4684 The big point of Skolelinux to me is that it is a complete
4685 distribution, ready to install. It has LDAP-support, MS Windows
4686 integration tools and so forth already configured, saving an
4687 administrator a lot of time and headache. We were using another Linux
4688 based thin-client system called Thinlinc, that has served us very
4689 well. But that Skolelinux is based on VNC and LTSP, to me, is better
4690 when it comes to the kind of multimedia used in schools. That is
4691 showing videos from Youtube or educational TV. It is also easier to
4692 mix thin clients with workstations, since the user settings will be the
4693 same. In our VNC-based solution you had to
"beat around the bush
" by
4694 setting up a second, hidden, home-directory for user settings for the
4695 workstations, because they will be different from the ones used on the
4696 thin clients. Skolelinux support for diskless workstations are very
4697 convenient since a school today often need to use a class room
4698 projector showing videos in full screen. That is easily done with a
4699 small integrated media computer running as a diskless workstation. You
4700 have only two installs to update and configure. One for the thin
4701 clients and one for the workstations. Also saving a lot of time. Our
4702 old system was also based on Redhat and CentOS. They are both very
4703 nice distributions, but they are sometimes painfully slow when it
4704 comes to updating multimedia support and multimedia programs (even
4705 such as Gimp), leaving us with a bit
"oldish
" applications. Debian is
4708 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
4709 Edu?
</strong
></p
>
4711 <p
>Debian is a bit too quick when it comes to updating. As an example
4712 we use old HP terminals as thinclients, and two times already this
4713 year (
2012) the updates you get from the repositories has stopped
4714 sound from working with them. It
's a kernel/ALSA issue. So you have
4715 to be more careful properly testing the updates before you run them in
4716 a production environment. This has never happened with CentOS.
</p
>
4718 <p
>I also would like to be able to set my own domain-settings at
4719 install time. In Skolelinux they are kind of hard coded into the
4720 distribution, when it comes to LDAP and at least samba integration.
4721 That is more a cosmetic/translation issue, and not a real problem.
4722 Running MS Windows applications within the Skolelinux environment needs
4723 to be better supported. That is, running them seamlessly via RDP, and
4724 support for single-sign on. That will make the transition to free
4725 software easier, because you can keep the applications you really
4726 need. No support will make it impossible if you work in a school where
4727 some applications can
't be open source. As for us we really need to
4728 run Adobe InDesign in our journalist classes. We run a journalist
4729 education, and is one of the very few non university ones that is ok:d
4730 by Svenska journalistförbundet (Swedish journalist association). Our
4731 education gives the pupils the right of membership there, once they
4732 are done. This is important if you want to get a job.
</p
>
4734 <p
>Adobe InDesign is the program most commonly used in newspapers and
4735 magazines. We used Quark Express before, but they seem to loose there
4736 market to Adobe. The only
"equivalent
" to InDesign in the opensource
4737 world is Scribus, and its not advanced enough. At least not according
4738 to the teacher. I think it would be possible to use it, because they
4739 are not supposed to learn a program, they are supposed to learn how to
4740 edit and compile a newspaper. But politically at our school we are not
4741 there yet. And Scribus lacks a lot of things you find i InDesign.
</p
>
4743 <p
>We used even a windows program for sound editing when it comes to
4744 the radio-journalist part. The year to come we are going to try
4745 Audacity. That software has the same kind of limitations compared to
4746 Adobe Audition, but that teacher is a bit more open minded. We have
4747 tried Ardour also, but that instead is more like a music studio
4748 program, not intended for the kind of editing taking place in a radio
4749 studio. Its way to complex and the GUI is to scattered when you only
4750 want to cut, make pass-overs, add extra channels and normalise. Those
4751 things you can do in Audacity, but its not as easy as in Audition. You
4752 have to do more things manually with envelopes, and that is a bit old
4753 fashion and timewasting. Its also harder to cut and move sound from
4754 one channel to another, which is a thing that you do frequently
4755 because you often find yourself needing to rearrange parts of the
4756 sound file.
</p
>
4758 <p
>So, I am not sure we will succeed in replacing even Audition, but we
4759 will try. The problem is the students have certain expectations when
4760 they start an education towards a profession. So the programs has to
4761 look and feel professional. Good thing with radio, there are many
4762 programs out there, that radio studios use, so its not as standardised
4763 as Newspaper editing. That means, it does not really matter what
4764 program they learn, because once they start working they still have to
4765 learn the program the studio uses, so instead focus has to be to learn
4766 the editing part without to much focus on a specific software.

4770 <p
>Myself I
'm running Linux Mint, or Ubuntu these days. I use almost
4771 only open source software, and preferably Linux based. When it comes
4772 to most used applications its OpenOffice, and Firefox (of course ;)
4775 <p
><strong
>Which strategy do you believe is the right one to use to
4776 get schools to use free software?
</strong
></p
>
4778 <p
>To get schools to use free software there has to be good open
4779 source software that are windows based, to ease the transition. But
4780 it
's also very important that the multimedia support is working
4781 flawlessly. The problems with Youtube, Twitter, Facebook and whatever
4782 will create problems when it comes to both teachers and
4783 students. Economy are also important for schools, so using thin
4784 clients, as long as they have good multimedia support, is a very good
4785 idea. It
's also important that the open source software works even for
4786 the administration. It
's hard to convince the teachers to stick with
4787 open source, if the principal has to run Windows. It also creates a
4788 problem if some classes has to use Windows for there tasks, since that
4789 will create a difference in
"status
" between classes, so a good
4790 support for running windows applications via the thin client (Linux)
4791 desktop is essential. At least at our school, where we have mixed
4792 level of educations, from high-school to journalist-school.

>Jeg heter Markus Gamenius og er
40 år. Utdannet biolog med ymse
5029 fag på siden. Har jobbet som lærer der jeg var driftsansvarlig på
5030 Ulsrud VGS i Oslo. Senere eide og jobbet jeg flere år i Linuxlabs AS,
5031 som jeg solgte til Redpill Linpro AS (den gangen Linpro AS). I dag
5032 jobber jeg med ulike investeringer, hovedsaklig i eiendom, men også i
5033 en del ulike IT-relaterte bedrifter.

5037 <p
>Fruen og jeg dro på en lengre seiltur i
2000, der jeg måtte ha
"noe
5038 å gjøre
" under hjemturen over Atlanteren. Jeg kjøpte et par bøker om
5039 Linux i en bokhandel i New York og ble veldig fascinert. Etter
5040 hjemkomsten begynte jeg å jobbe på Ulsrud VGS, som naturfagslærer, men
5041 som IT-interessert ble jeg fort en del av den nye IT-satsningen som
5042 skulle løfte Ulsrud og gi skolen en bedre rykte. Vi hadde ganske
5043 mange maskiner, som gikk på Win98 og to servere som ble oppgradert til
5044 Win2000. Systemene var ustabil og dårlige. På leting etter noe
5045 bedre, uten å knekke ryggen økonomisk, kom jeg over
"Linux i Skolen
"
5046 og Skolelinux. Jeg tok kontakt med miljøet og en gjeng møtte opp på
5047 skolen, der vi gjorde en liten testinstallasjon. Etter et par år var
5048 ryggraden på skolen Linux (Skolelinux) og vi hadde flere hundre
5049 maskiner, både tynne klienter (gamle og nye), bærbare (Debian) og noen
5050 stasjonære (Win2000). På et tidspunkt var Ulsrud den råeste IT-skolen
5051 og det irriterte skolesjefen i Oslo, da de satset hardt på

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

5056 <p
>Det som gjorde at vi fikk inn Skolelinux var ene og alene
5057 økonomiske. Det faktum at vi slapp å kjøpe masse nye lisenser og at
5058 vi kunne bruke gammel hardware. Alt i alt gjorde dette at vi sparte
5059 mye, men i stede for å bruke mindre på IT brukte vi det vi sparte på å
5060 skaffe mer hardware og på den måten gi det beste tilbudet i landet til
5061 våre elever. For oss som driftet var det himmel å ha et system som
5062 gikk å administrere sentralt og effektivt. Det var heller ikke så
5063 dumt at vi kunne
"låse
" maskinene mer effektivt enn vi kunne med
5064 Microsoft Windows, slik at vi slapp mye feil og problemer som ble
5065 forårsaket av
"kreative
" elever.

5067 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
5069 <p
>Det vi slet med var mangelen av en del programmer lærerne ville ha.
5070 Husker ikke alle, men det var et knippe med pedagogiske programmer de
5071 ikke fikk. I dag tror jeg det problemet er langt mindre da det meste
5072 av disse kjøres gjennom nettleseren.

5076 <p
>Jeg bruker mye Apple i dag og er ikke så stolt av det, men jeg har
5077 både OpenOffice, Firefox og en del andre programmer på den bærbare.
5078 Firefox brukes mest av disse. På Apple-serveren hjemme bruker jeg
5079 HandBrake mye, og jeg har installert OpenWRT på flere av
5080 basestasjonene både hjemme og på jobben. I tillegg til det har jeg i
5081 flere år finansiert et prosjekt som heter
5082 <a href=
"http://www.found.no/
">Found IT
</a
>. Dette er et prosjekt der
5083 vi lager et rammeverk for søk, der alt vi bruker fri programvare. Det
5084 er Alex Brasetvik som er daglig leder i Found IT.

5087 skoler til å ta i bruk fri programvare?
</strong
></p

5089 <p
>Når det gjelder IT og skole er fortsatt økonomi veldig viktig. Så
5090 man må oppfylle minimumskravene (ikke være best, men bra nok) og selge
5091 seg inn på hvor mye man sparer. Det betyr selvsagt at man sparer på
5092 lisenser, men også på driftsinnsats. Men nå når jeg ikke er en aktiv
5093 del av miljøet lenger hører jeg nesten ingen ting om fri programvare.
5094 Jeg stiller meg da spørsmålet om det har blitt stille rundt miljøet,
5095 eller om jeg kun så det tydeligere før når jeg var aktiv? Uansett er
5096 det for stille rundt Skolelinux-prosjektet nå.

5106 another interview with the people behind

">Debian Edu and Skolelinux
</a
>.
5108 This time we get to know José Luis Redrejo Rodríguez, one of our great
5109 helpers from Spain. His effort was the reason we added support for
5110 several desktop types (KDE, Gnome and most recently LXDE) in Debian
5111 Edu, and have all of these available in the recently published

</strong

>
5117 <p
>I
'm a father, teacher and engineer who is working for the Education
5118 ministry of the Region of Extremadura (Spain) in the implementation of
5119 ICT in schools
</p
>
5121 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5122 project?
</strong
></p
>
5124 <p
>At
2006, I verified that both, we in Extremadura and Skolelinux
5125 project, had been working in parallel for some years, doing very
5126 similar things, using very similar tools and with similar targets, so
5127 I decided it was time to join forces as much as possible.
</p
>
5129 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5130 Edu?
</strong
></p
>
5132 <p
>A community of highly skilled experts working together, with a
5133 really open schema of collaboration and work. I really love the
5134 concepts of Do-ocracy and Merit-ocracy and the way these concepts are
5135 been used everyday inside Debian Edu.
</p
>
5137 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
5138 Edu?
</strong
></p
>
5140 <p
>Sometimes the differences in the implementations, laws or
5141 economical and technical resources in the different countries don
't
5142 allow us to agree in the same solution for all of us, and several
5143 approaches are needed, what is a waste of effort. Also, there is a
5144 lack of more man power to be able to follow the fast evolution of the
5145 technologies in school.
</p
>
5147 <p
><strong
>Which free software do you use daily?
</strong
></p
>
5149 <p
>Debian, of course, and due to my kind of job I am most of my time
5150 between Iceweasel,

">Geany
</a
> and
5151 <a href=
"http://www.ohloh.net/p/gnome-terminator
">Terminator
</a
>.
</p
>
5153 <p
><strong
>Which strategy do you believe is the right one to use to
5154 get schools to use free software?
</strong
></p
>
5156 <p
>I think there is not a single strategy because there are very
5157 different scenarios: schools with mixed proprietary and free
5158 environments, schools using only workstations, other schools using
5159 laptops, netbooks, tablets, interactive white-boards, etc.
</p
>
5161 <p
>Also the range of ages of the students is very broad and you can
5162 not use the same solutions for primary schools and secondary or even
5163 universities. So different strategies are needed.
</p
>
5165 <p
>But, looking at these differences, and looking back to the things
5166 we
've done and implemented, and the places were we have spent most of
5167 our forces, I think we should focus as much as possible in free
5168 multi-platform environments, using only standards tools, and moving
5169 more and more to Internet or network solutions that could be deployed
5170 using wireless. I think we
'll see more and more personal devices in
5171 the schools, devices the students and teachers will take home with
5172 them, so the solutions must be able to be taken at home and continue
5173 working there.

">Debian Edu
5184 based on Squeeze
</a
>, I came across some issues that should be
5185 addressed in the Wheezy release. I finally found time to wrap up my
5186 notes and provide quick summary of what I found, with a bit
5187 explanation.
</p
>
5191 <li
>We need to rewrite our package installation framework, as tasksel
5192 changed from using tasksel tasks to using meta packages (aka packages
5193 with dependencies like our education-* packages), and our installation
5194 system depend on tasksel tasks in
5195 /usr/share/tasksel/debian-edu-tasks.desc for package
5196 installation.
</li
>
5198 <li
>Enable Kerberos login for more services. Now with the Kerberos
5199 foundation in place, we should use it to get single sign on with more
5200 services, and avoiding unneeded password / login questions. We should
5201 at least try to enable it for these services:
5204 <li
>CUPS for admins to add/configure printers and users when using
5206 <li
>Nagios for admins checking the system status.
</li
>
5207 <li
>GOsa for admins updating LDAP and users changing their passwords.
</li
>
5208 <li
>LDAP for admins updating LDAP.
</li
>
5209 <li
>Squid for users when exam mode / filtering is active.
</li
>
5210 <li
>ssh for admins and users to save a password prompt.
</li
>
5212 </ul
></li
>
5214 <li
>When we move GOsa to use Kerberos instead of LDAP bind to
5215 authenticate users, we should try to block or at least limit access to
5216 use LDAP bind for authentication, to ensure Kerberos is used when it
5217 is intended, and nothing fall back to using the less safe LDAP bind
</li
>
5219 <li
>Merge debian-edu-config and debian-edu-install. The split made
5220 sense when d-e-install did a lot more, but these days it is just an
5221 inconvenience when we update the debconf preseeding values.
</li
>
5223 <li
>Fix partman-auto to allow us to abort the installation before
5224 touching the disk if the disk is too small. This is
5225 <a href=
"http://bugs.debian.org/
653305">BTS report #
653305</a
> and the
5226 d-i developers are fine with the patch and someone just need to apply
5227 it and upload. After this is done we need to adjust
5228 debian-edu-install to use this new hook.
</li
>
5230 <li
>Adjust to new LTSP framework (boot time config instead of install
5231 time config). LTSP changed its design, and our hooks to install
5232 packages and update the configuration is most likely not going to work
5235 <li
>Consider switching to NBD instead of NFS for LTSP root, to allow
5236 the Kernel to cache files in its normal file cache, possibly speeding
5237 up KDE login on slow networks.
</li
>
5239 <li
>Make it possible to create expired user passwords that need to
5240 change on first login. This is useful when handing out password on
5241 paper, to make sure only the user know the password. This require
5242 fixes to the PAM handling of kdm and gdm.
</li
>
5244 <li
>Make GUI for adding new machines automatically from sitesummary.
5245 The current command line script is not very friendly to people most
5246 familiar with GUIs. This should probably be integrated into GOsa to
5247 have it available where the admin will be looking for it..
</li
>
5249 <li
>We should find way for Nagios to check that the DHCP service
5250 actually is working (as in handling out IP addresses). None of the
5251 Nagios checks I have found so far have been working for me.
</li
>
5253 <li
>We should switch from libpam-nss-ldapd to sssd for all profiles
5254 using LDAP, and not only on for roaming workstations, to have less
5255 packages to configure and consistent setup across all profiles.
</li
>
5257 <li
>We should configure Kerberos to update LDAP and Samba password
5258 when changing password using the Kerberos protocol. The hook was
5259 requested in
<a href=
"http://bugs.debian.org/
588968">BTS report
5260 #
588968</a
> and is now available in Wheezy. We might need to write a
5261 MIT Kerberos plugin in C to get this.
</li
>
5263 <li
>We should clean up the set of applications installed by default.
5266 <li
>reduce the number of chemistry visualisers
</li
>
5267 <li
>consider dropping xpaint
</li

5273 examples too. For popular laptops to work out of the box, such
5274 firmware need to be installed from non-free, and we should provide
5275 some GUI to do this. Ubuntu already have this implemented, and we
5276 could consider using their packages. At the moment we have some

2010, Mike Gabriel showed up on the
5331 <a href=
"http://www.skolelinux.org/
">Debian Edu and Skolelinux
</a

5332 mailing list. He quickly proved to be a valuable developer, and
5333 thanks to his tireless effort we now have Kerberos integrated into the

</p
>
5337 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
5339 <p
>My name is Mike Gabriel, I am
38 years old and live near Kiel,
5340 Schleswig-Holstein, Germany. I live together with a wonderful partner
5341 (Angela Fuß) and two own children and two bonus children (contributed
5342 by Angela).
</p
>
5344 <p
>During the day I am part-time employed as a system administrator
5345 and part-time working as an IT consultant. The consultancy work
5346 touches free software topics wherever and whenever possible. During
5347 the nights I am a free software developer. In the gaps I also train in
5348 becoming an osteopath.
</p
>
5350 <p
>Starting in
2010 we (Andreas Buchholz, Angela Fuß, Mike Gabriel)
5351 have set up a free software project in the area of Kiel that aims at
5352 introducing free software into schools. The project
's name is
5353 "IT-Zukunft Schule
" (IT future for schools). The project links IT
5354 skills with communication skills.
</p
>
5356 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5357 project?
</strong
></p
>
5359 <p
>While preparing our own customised Linux distribution for
5360 "IT-Zukunft Schule
" we were repeatedly asked if we really wanted to
5361 reinvent the wheel. What schools really need is already available,
5362 people said. From this impulse we started evaluating other Linux
5363 distributions that target being used for school networks.
</p
>
5365 <p
>At the end we short-listed two approaches and compared them: a
5366 commercial Linux distribution developed by a company in Bremen,
5367 Germany, and Skolelinux / Debian Edu. Between
12/
2010 and
03/
2011 we
5368 went to several events and met people being responsible for marketing
5369 and development of either of the distributions. Skolelinux / Debian
5370 Edu was by far much more convincing compared to the other product that
5371 got short-listed beforehand--across the full spectrum. What was most
5372 attractive for me personally: the perspective of collaboration within
5373 the developmental branch of the Debian Edu project itself.
</p
>
5375 <p
>In parallel with this, we talked to many local and not-so-local
5376 people. People teaching at schools, headmasters, politicians, data
5377 protection experts, other IT professionals.
</p
>
5379 <p
>We came to two conclusions:
</p
>
5381 <p
>First, a technical conclusion: What schools need is available in
5382 bits and pieces here and there, and none of the solutions really fit
5383 by
100%. Any school we have seen has a very individual IT setup
5384 whereas most of each school
's requirements could mapped by a standard
5385 IT solution. The requirement to this IT solution is flexibility and
5386 customisability, so that individual adaptations here and there are
5387 possible. In terms of re-distributing and rolling out such a
5388 standardised IT system for schools (a system that is still to some
5389 degree customisable) there is still a lot of work to do here
5390 locally. Debian Edu / Skolelinux has been our choice as the starting
5393 <p
>Second, a holistic conclusion: What schools need does not exist at
5394 all (or we missed it so far). There are several technical solutions
5395 for handling IT at schools that tend to make a good impression. What
5396 has been missing completely here in Germany, though, is the enrolment
5397 of people into using IT and teaching with IT.
"IT-Zukunft Schule
"
5398 tries to provide an approach for this.
</p
>
5400 <p
>Only some schools have some sort of a media concept which explains,
5401 defines and gives guidance on how to use IT in class. Most schools in
5402 Northern Germany do not have an IT service provider, the school
's IT
5403 equipment is managed by one or (if the school is lucky) two (admin)
5404 teachers, most of the workload these admin teachers get done in there
5405 spare time.
</p
>
5407 <p
>We were surprised that only a very few admin teachers were
5408 networked with colleagues from other schools. Basically, every school
5409 here around has its individual approach of providing IT equipment to
5410 teachers and students and the exchange of ideas has been quasi
5411 non-existent until
2010/
2011.
</p
>
5413 <p
>Quite some (non-admin) teachers try to avoid using IT technology in
5414 class as a learning medium completely. Several reasons for this
5415 avoidance do exist.
</p
>
5417 <p
>We discovered that no-one has ever taken a closer look at this
5418 social part of IT management in schools, so far. On our quest journey
5419 for a technical IT solution for schools, we discussed this issue with
5420 several teachers, headmasters, politicians, other IT professionals and
5421 they all confirmed: a holistic approach of considering IT management
5422 at schools, an approach that includes the people in place, will be new
5423 and probably a gain for all.
</p
>
5425 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5426 Edu?
</strong
></p
>
5428 <p
>There is a list of advantages: international context, openness to
5429 any kind of contributions, do-ocracy policy, the closeness to Debian,
5430 the different installation scenarios possible (from stand-alone
5431 workstation to complex multi-server sites), the transparency within
5432 project communication, honest communication within the group of
5433 developers, etc.

5436 Edu?
</strong

5438 <p
>Every coin has two sides:
</p
>
5440 <p
>Technically:
<a href=
"http://bugs.debian.org/
311188">BTS issue
5441 #
311188</a
>, tricky upgradability of a Debian Edu main server, network
5442 client installations on top of a plain vanilla Debian installation
5443 should become possible sometime in the near future, one could think
5444 about splitting the very complex package debian-edu-config into
5445 several portions (to make it easier for new developers to
5446 contribute).
</p
>
5448 <p
>Another issue I see is that we (as Debian Edu developers) should
5449 find out more about the network of people who do the marketing for
5450 Debian Edu / Skolelinux. There is a very active group in Germany
5451 promoting Skolelinux on the bigger Linux Days within Germany. Are
5452 there other groups like that in other countries? How can we bring
5453 these marketing people together (marketing group A with group B and
5454 all of them with the group of Debian Edu developers)? During the last
5455 meeting of the German Skolelinux group, I got the impression of people
5456 there being rather disconnected from the development department of
5457 Debian Edu / Skolelinux.

><strong
>Which free software do you use daily?
</strong
></p
>
5461 <p
>For my daily business, I do not use commercial software at all.
</p
>
5463 <p
>For normal stuff I use Iceweasel/Firefox, Libreoffice.org. For
5464 serious text writing I prefer LaTeX. I use gimp, inkscape, scribus for
5465 more artistic tasks. I run virtual machines in KVM and Virtualbox.
</p

5467 <p
>I am one of the upstream developers of X2Go. In
2010 I started the
5468 development of a Python based X2Go Client, called PyHoca-GUI.
5469 PyHoca-GUI has brought forth a Python X2Go Client API that currently
5470 is being integrated in Ubuntu
's software center.
</p
>
5472 <p
>For communications I have my own Kolab server running using Horde
5473 as web-based groupware client. For IRC I love to use irssi, for Jabber
5474 I have several clients that I use, mostly pidgin, though. I am also
5475 the Debian maintainer of Coccinella, a Jabber-based interactive
5476 whiteboard.

12
5506 years (since

5507 also inclusive) school leading to all kind of general levels, such as

5515 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5516 project?
</strong
></p
>
5518 <p
>We had tried different Linux based school servers, when members of
5519 my local Linux User Group (LUG OWL) detected Skolelinux. I remember
5520 very well, being part of a party celebrating the Linux New Media Award
5521 (
"Best Newcomer Distribution
", also nominated: Ubuntu) that was given
5522 to Skolelinux at Linux World Exposition in Frankfurt,
2005 (IIRC). Few
5523 months later, I had the chance to join a developer meeting in Ulsrud
5524 (Oslo) and to hand out the award to Knut Yrvin and others. For more
5525 than
7 years, Skolelinux is part of our schools infrastructure, namely
5526 our main server (tjener), one LTSP (today without thin clients), and
5527 approximately
50 work stations. Most of these have the option to boot a
5528 locally installed Skolelinux image. As a consequence, I joined quite
5529 a few events dealing with free software or Linux, and met many Debian
5530 (Edu) developers. All of them seemed quite nice and competent to me,
5531 one more reason to stick to Skolelinux.

5534 Edu?
</strong
></p
>
5536 <p
>Debian driven, you are given all the advantages of a community
5537 project including well maintained updates. Once, you are familiar with
5538 the network layout, you can easily roll out an entire educational
5539 computer infrastructure, from just one installation media. As only
5540 free software (FOSS) is used, that supports even elderly hardware,
5541 up-sizing your IT equipment is only limited by space (i.e. available
5542 labs). Especially if you run a LTSP thin client server, your
5543 administration costs tend towards zero.
</p
>
5545 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
5546 Edu?
</strong
></p
>
5548 <p
>While Debian
's stability has loads of advantages for servers, this
5549 might be different in some cases for clients: Schools with unlimited
5550 budget might buy new hardware with components that are not yet
5551 supported by Debian stable, or wish to use more recent versions of
5552 office packages or desktop environments. These schools have the
5553 option to run Debian testing or other distributions - if they have the
5554 capacity to do so. Another issue is that Debian release cycles
5555 include a wide range of changes; therefor a high percentage of human
5556 power seems to be absorbed by just keeping the features of Skolelinux
5557 within the new setting of the version to come. During this process,
5558 the cogs of Debian Edu are getting more and more professional,
5559 i.e. harder to understand for novices.

5577 <li
>Make budget baskets corresponding: In Germany
's public schools
5578 there are more or less fixed budgets for IT equipment (including
5579 licenses), so schools won

5581 share among German Skolelinux schools.

5583 <li

5636 <p
>Har i mange år drevet med musikk og en av grunnen til at Rosegarden
5637 falt i smak for min del, var fordi denne fungere og ligner mest på
5638 Windows-programmet (cubase) jeg jobbet mye med da jeg i mine yngre
5639 dager var «Windows fanatiker». Ble introdusert til Linux av en kompis

5652 <p
>Skolelinux er enkelt å holde i drift og masse flotte programmer som
5653 geogebra, ktouch og kgeografi følger med pakken. Man kan ta i bruk
5654 gamle PC-er igjen, slik at skoler med dårlig råd får opp en brukbar
5655 PC-park. PC-er som er ca
6-
9 år gamle fungere tilfredstillende, bare
5656 de har
512 MB RAM eller mer.

5658 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
5660 <p
>Ulempene er at noen av de pedagogiske programmene som lærene ønsker
5661 å bruke fungere dårlig med Linux. Mye pga. av at disse programmene
5662 blir ikke laget til Linuxbaserte operativsystemer.
</p
>
5664 <p
>Video- og bilde-redigering har dessverre en del mangler, mange av
5665 programmene har en tendens til og krasje. Det gjelder blant annet
5666 <a href=
"http://www.kdenlive.org/
">kdenlive
</a
> og
5667 <a href=
"http://www.openshotvideo.com/
">openshot
</a
>, for å nevne
5668 noen. De er ikke stabile nok. Når elevene kommer med filmsnutter de
5669 ønsker og jobbe med, så godtar ikke programmene filene, og når elevene
5670 jobber med redigering bare krasjer programmene uten forvarsel. Det er
5671 for vanskelig å få noe som bare fungerer ut av boksen her. Når en elev
5672 plugger inn et videokamera eller fotoapparat så er det alltid noe som
5673 ikke vil fungere. Programmene godtar ikke format, godtar ikke
5674 kameraet, osv., osv. Det er dessverre med på og dra ned en positiv
5675 opplevelse av bruk av fri programvare.
</p

5677 <p
>Man må ofte bruke flere en et video redigerings program før og få
5678 fullført en ønsket oppgave.

5680 <p
>Eksempel:
</p
>
5682 <p
>Hvis det ene programmet ikke vil ta i mot videofilen klarer et

5697 Lydsystemet kan også være et mareritt. Konkret snakker jeg om når du
5698 bruker for eksempel et smartboard, så følger det med USB-lydkort på
5699 disse. Problemet ligger her i at systemet ikke vil velge rett
5700 lydkort, så man må inn med padevchooser for å sette opp PulseAudio
5701 til og velge at USB-lydkortet skal brukes. Det blir for tungvindt for
5702 lærene, de ønsker at ting skal fungere med en gang. (min løsning på
5703 det problemet ble at jeg måtte deaktivere lydkortet som fantes på
5704 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
5727 publish another interview with the people behind
5728 <a href=
"http://www.skolelinux.org/
">Debian Edu and Skolelinux
</a
>.
5729 This time it is one of our German developers, who have helped out over the
5730 years to make sure both a lot of major but also a lot of the minor
5731 details get right before release.
5733 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
5735 <p
>My name is Jürgen Leibner, I
'm
49 years old and living in
5736 Bielefeld, a town in northern Germany. I worked nearly
20 years as
5737 certified engineer in the department for plant design and layout of an
5738 international company for machinery and equipment. Since
2011 I
'm a
5739 certified technical writer (tekom e.V.) and doing technical
5740 documentations for a steam turbine manufacturer. From April this year
5741 I will manage the department of technical documentation at a
5742 manufacturer of automation and assembly line engineering.
</p
>
5744 <p
>My first contact with linux was around
1993. Since that time I used
5745 it at work and at home repeatedly but not exclusively as I do now at
5746 home since
2006.
</p
>
5748 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5749 project?
</strong
></p
>
5751 <p
>Once a day in the early year of
2001 when I wanted to fetch my
5752 daughter from primary school, there was a teacher sitting in the
5753 middle of
20 old computers trying to boot them and he failed. I helped
5754 him to get them booting. That was seen by the school director and she
5755 asked me if I would like to manage that the school gets all that old
5756 computers in use. I answered:
"Yes
".
</p
>
5758 <p
>Some weeks later every of the
10 classrooms had one computer
5759 running Windows98. I began to collect old computers and equipment as
5760 gifts and installed the first computer room with a peer-to-peer
5761 network. I did my work at school without being payed in my spare time
5762 and with a lot of fun. About one year later the school was connected
5763 to Internet and a local area network was installed in the school
5764 building. That was the time to have a server and I knew it must be a
5765 Linux server to be able to fulfil all the wishes of the teachers and
5766 being able to do this in a transparent and economic way, without extra
5767 costs for things like licence and software. So I searched for a
5768 school server system running under Linux and I found a couple of
5769 people nearby who founded
'skolelinux.de
'. It was the Skolelinux
5770 prerelease
32 I first tried out for being used at the school. I
5771 managed the IT of that school until the municipal authority took over
5772 the IT management and centralised the services for all schools in
5773 Bielefeld in December of
2006.

>What do you see as the advantages of Skolelinux/Debian
5776 Edu?
</strong

5778 <p
>When I
'm looking back to the beginning, there were other advantages
5779 for me as today.
</p
>
5781 <p
>In the past there were advantages like:
</p
>
5785 <li
>I don
't need to buy it so it generates no costs to the school as
5786 they had little money to spent for computers and software.
</li
>
5788 <li
>It has a licence which grands all rights to use it without
5791 <li
>It was more able to fit all requirements of a server system for
5792 schools than a Microsoft server system, even if there are only Windows
5793 clients because of it
's preconfigured overall concept of being a
5794 infrastructure solution and community for schools, not only a
5797 <li
>I was able to configure the server to the needs of the
5800 </ul
></p
>
5802 <p
>Today some of the advantages has been lost, changed or new ones
5803 came up in this way:
</p
>
5807 <li
>Most schools here do have money to buy hardware and software
5810 <li
>They are today mostly managed from central IT departments which
5811 have own concepts which often do not fit to Debian Edu concepts
5812 because they are to close to Microsoft ideology.
</li
>
5814 <li
>With the Squeeze version of Debian Edu which now uses GOsa² for
5815 management I feel more able to manage the daily tasks than with the
5816 interfaces used in the past.
</li
>
5818 <li
>It is more modular than in the past and fits even better to the
5819 different needs.
</li
>
5821 <li
>The documentation is usable and gets better every day.
</li
>
5823 <li
>More people than ever before are using Debian Edu all over the
5824 world and so the community, which is an very important part I think,
5825 is sharing knowledge and minds.
</li
>
5827 <li
>Most, maybe all, of the technical requirements for schools are
5828 solved today by Debian Edu.
</li

>
5832 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
5833 Edu?
</strong

5837 <li
>There are too few IT companies able to integrate Debian Edu into
5838 their product portfolio for serving schools with concepts or even
5839 whole municipality areas.
</li
>
5841 <li
>Debian Edu has beside other free and open software projects not
5842 enough lobbyists which promote free and open software to
5843 politicians.

'm aware of.

>
5849 <p
><strong
>Which free software do you use daily?
</strong
></p
>
5851 <p
>I use Debian stable on my home server and on my little desktop
5852 computer. On my laptop I use Debian testing/sid. The applications I
5853 use on my laptop and my desktop are Open/Libre-office, Iceweasel,
5854 KMail, DigiKam, Amarok, Dolphin, okular and all the other programs I
5855 need from the KDE environment. On console I use newsbeuter, mutt,
5856 screen, irssi and all the other famous and useful tools.
</p
>
5858 <p
>My home server provides mail services with exim, dovecot, roundcube
5859 and mutt over ssh on the console, file services with samba, NFS,
5860 rsync, web services with apache, moinmoin-wiki, multimedia services
5861 with gallery2 and mediatomb and database services with MySQL for me
5862 and the whole family. I probably forgot something.

>Da jeg googlet etter noe annet kom jeg tilfeldigvis over
5879 <a href=
"http://www.duo.uio.no/sok/work.html?WORKID=
58309">en
5880 hovedfagsoppgave
</a
> ved Universitetet i Oslo som diskuterer verdien
5881 av GPLs fire friheter for brukerne av IT-systemer. Jeg ble fascinert
5882 over det som presenteres der. Her er sammendraget:
</p
>
5884 <p
><blockquote
>
5886 <p
>Motivasjonen til å skrive denne oppgaven er en personlig undring
5887 over hvorfor det primært, og ofte eksklusivt, fokuseres på det
5888 økonomiske aspektet ved utredninger om fri programvare er et godt valg
5889 for det offentlige. Fri og produsenteid programvare bygger på
5890 fundamentalt forskjellige ideologier som kan ha implikasjoner utover
5891 økonomiske kostnader. Kunnskapskulturen som er med på å definere fri
5892 programvare er basert på åpenhet, og er en verdi i seg selv.
</p
>
5894 <p
>Oppgavens tema er programvarelisensen GPL og frihet. GPL-lisensiert
5895 programvare gir visse friheter i forhold til produsenteid
5896 programvare. Mitt spørsmål er om, og eventuelt i hvilken utstrekning,
5897 disse frihetene blir benyttet av ulike brukere og hvordan de
5898 manifesterer seg for disse brukerne. Sentrale spørsmål i oppgaven
5902 <li
>Hvordan fordeles handlekraft gjennom lisensieringen av programvaren?
</li
>
5903 <li
>Hvilke konsekvenser har programvarelisensen for de ulike brukere?
</li
>
5906 <p
>Fri programvare gir blant annet brukeren mulighet til å studere og
5907 modifisere kildekoden. Denne formen for frihet erverves gjennom
5908 kunnskap og krever at brukeren også er en ekspert. Hva skjer med
5909 frihetene til GPL når sluttbrukeren er en annen? Dette diskuteres i
5910 dialog med informantene.
</p
>
5912 <p
>Jeg har i denne oppgaven samlet inn intervjudata fra IKT-ansvarlige
5913 ved grunnskolene i Nittedal kommune, driftsansvarlig og IKT-veilederen
5914 for skolene i kommunen, samt IKT-koordinator for utdanning i Akershus
5915 fylkeskommune og bokmåloversettere av OpenOffice.org. Den empiriske
5916 delen av oppgaven er delt inn i to seksjoner; den første omhandler
5917 operativsystemet Skolelinux, den andre kontorprogrampakken
5918 OpenOffice.org.
</p
>
5920 <p
>Som vi vil se gir GPL lokal frihet og kontroll gjennom omfordeling
5921 av makt fra produsent til bruker. Brukerens makt analyseres gjennom
5922 begrepene brukermedvirkning og handlingsfrihet. Det blir også lagt
5923 vekt på strukturelle forhold rundt bruken av teknologi, og spesielt de
5924 økonomiske begrepene nettverkseksternaliteter, innlåsing og
5925 stiavhengighet. Dette er begreper av spesiell nytte når objektet som
5926 omsettes eller distribueres er et kommunikasjonsprodukt, fordi verdien
5927 til et slikt gode for en potensiell bruker avhenger av antall
5928 eksisterende brukere av godet. I tilknytning til denne problematikken
5929 inneholder oppgaven også en diskusjon rundt åpne standarder og
5932 <p
>Oppgaven konkluderer med at de «fire frihetene» som GPL-lisensen er
5933 laget for å beskytte er av avgjørende betydning for bruken av
5934 OpenOffice.org og Skolelinux, i Akershus fylkeskommune såvel som i
5935 skolene i Nittedal. Distribusjonen av handlekraft er ikke helt
5936 symmetrisk. Det er først og fremst de profesjonelle utviklerne i
5937 Skolelinux som direkte kan nyttiggjøre seg friheten til å endre kode,
5938 mens en sluttbruker som Nittedal kommune nyttiggjør seg den økonomiske
5939 friheten til å kunne distribuere programmene. Det er imidlertid også
5940 slik at ingen aktør klarer seg uten alle disse «frihetene».

2006, men der ligger ikke
5944 komplett oppgave tilgjengelig. På tide å holde et øye med

5957 Skolelinux
</a

5958 setting together all the pieces. This time I present to you Andreas
5959 Mundt, who have been part of the technical development team several
5960 years. He was also a key contributor in getting GOsa and Kerberos set
5961 up in the recently released

5967 <p
>My name is Andreas Mundt, I grew up in south Germany. After
5968 studying Physics I spent several years at university doing research in
5969 Quantum Optics. After that I worked some years in an optics company.
5970 Finally I decided to turn over a new leaf in my life and started
5971 teaching
10 to
19 years old kids at school. I teach math, physics,
5972 information technology and science/technology.

5974 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5975 project?
</strong
></p
>
5977 <p
>Already before I switched to teaching, I followed the Debian Edu
5978 project because of my interest in education and Debian. Within the
5979 qualification/training period for the teaching, I started
5980 contributing.
</p
>
5982 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5983 Edu?
</strong
></p
>
5985 <p
>The advantages of Debian Edu are the well known name, the
5986 out-of-the-box philosophy and of course the great free software of the
5987 Debian Project!
</p
>
5989 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
5990 Edu?
</strong
></p
>
5992 <p
>As every coin has two sides, the out-of-the-box philosophy has its
5993 downside, too. In my opinion, it is hard to modify and tweak the
5994 setup, if you need or want that. Further more, it is not easily
5995 possible to upgrade the system to a new release. It takes much too
5996 long after a Debian release to prepare the -Edu release, perhaps
5997 because the number of developers working on the core of the code is
5998 rather small and often busy elsewhere.

>
6003 <p
><strong
>Which free software do you use daily?
</strong
></p
>
6005 <p
>I am only using non-free software if I am forced to and run Debian
6006 on all my machines. For documents I prefer LaTeX and PGF/TikZ, then
6007 mutt and iceweasel for email respectively web browsing. At school I
6008 have Arduino and Fritzing in use for a micro controller project.
</p
>
6010 <p
><strong
>Which strategy do you believe is the right one to use to
6011 get schools to use free software?
</strong
></p
>
6013 <p
>One of the major problems is the vendor lock-in from top to bottom:
6014 Especially in combination with ignorant government employees and
6015 politicians, this works out great for the
"market-leader
". The school
6016 administration here in Baden-Wuerttemberg is occupied by that vendor.
6017 Documents have to be prepared in non-free, proprietary formats. Even
6018 free browsers do not work for the school administration. Publishers
6019 of school books provide software only for proprietary platforms.
</p
>
6021 <p
>To change this, political work is very important. Parts of the
6022 political spectrum have become aware of the problem in the last years.
6023 However it takes quite some time and courageous politicians to
'free
'
6024 the system. There is currently some discussion about
"Open Data
" and
6025 "Free/Open Standards
". I am not sure if all the involved parties have
6026 a clue about the potential of these ideas, and probably only a
6027 fraction takes them seriously. However it might slowly make free
6028 software and the philosophy behind it more known and popular.

6097 Lenny installation using LTSP diskless workstations, and in the
6098 process I discovered something very surprising. The reason the KDE
6099 menu was responding slow when using it for the first time, was mostly
6100 due to the way KDE find application icons. I discovered that showing
6101 the Multimedia menu would cause more than
20 000 IP packages to be
6102 passed between the LTSP client and the NFS server. Most of these were
6104 NFS LOOKUP calls, resulting in a NFS3ERR_NOENT response. Because the
6105 ping times between the client and the server were in the range
2-
20
6106 ms, the menus would be very slow. Looking at the strace of kicker in
6107 Lenny (or plasma-desktop i Squeeze - same problem there), I see that
6108 the source of these NFS calls are access(
2) system calls for
6109 non-existing files. KDE can do hundreds of access(
2) calls to find
6110 one icon file. In my example, just finding the mplayer icon required
6111 around
230 access(
2) calls.
</p
>
6113 <p
>The KDE code seem to search for icons using a list of icon
6114 directories, and the list of possible directories is large. In
6115 (almost) each directory, it look for files ending in .png, .svgz, .svg
6116 and .xpm. The result is a very slow KDE menu when /usr/ is NFS
6117 mounted. Showing a single sub menu may result in thousands of NFS
6118 requests. I am not the first one to discover this. I found a
6119 <a href=
"https://bugs.kde.org/show_bug.cgi?id=
211416">KDE bug report
6120 from
2009</a
> about this problem, and it is still unsolved.
</p
>
6122 <p
>My solution to speed up the KDE menu was to create a package
6123 kde-icon-cache that upon installation will look at all .desktop files
6124 used to generate the KDE menu, find their icons, search the icon paths
6125 for the file that KDE will end up finding at run time, and copying the
6126 icon file to /var/lib/kde-icon-cache/. Finally, I add symlinks to
6127 these icon files in one of the first directories where KDE will look
6128 for them. This cut down the number of file accesses required to find
6129 one icon from several hundred to less than
5, and make the KDE menu
6130 almost instantaneous. I
'm not quite sure where to make the package
6131 publicly available, so for now it is only available on request.
</p
>
6133 <p
>The bug report mention that this do not only affect the KDE menu
6134 and icon handling, but also the login process. Not quite sure how to
6135 speed up that part without replacing NFS with for example NBD, and
6136 that is not really an option at the moment.

>Germany is a core area for the
6169 <a href=

</a

6170 user community, and this time I managed to get hold of Wolfgang
6171 Schweer, a valuable contributor to the project from Germany.
6173 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
6175 <p
>I
've studied Mathematics at the university
'Ruhr-Universität
' in
6176 Bochum, Germany. Since
1981 I
'm working as a teacher at the school
6177 "<a href=
"http://www.westfalenkolleg-dortmund.de/
">Westfalen-Kolleg
6178 Dortmund
</a
>", a second chance school. Here, young adults is given
6179 the opportunity to get further education in order to do the school
6180 examination
'Abitur
', which will allow to study at a university. This
6181 second chance is of value for those who want a better job perspective
6182 or failed to get a higher school examination being teens.
</p
>
6184 <p
>Besides teaching I was involved in developing online courses for a
6185 blended learning project called
'abitur-online.nrw
' and in some other
6186 information technology related projects. For about ten years I
've been
6187 teacher and coordinator for the
'abitur-online
' project at my
6188 school. Being now in my early sixties, I
've decided to leave school at
6189 the end of April this year.
</p
>
6191 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
6192 project?
</strong
></p
>
6194 <p
>The first information about Skolelinux must have come to my
6195 attention years ago and somehow related to LTSP (Linux Terminal Server
6196 Project). At school, we had set up a network at the beginning of
1997
6197 using Suse Linux on the desktop, replacing a Novell network. Since
6198 2002, we used old machines from the city council of Dortmund as thin
6199 clients (LTSP, later Ubuntu/Lessdisks) cause new hardware was out of
6200 reach. At home I
'm using Debian since years and - subscribed to the
6201 Debian news letter - heard from time to time about Skolelinux. About
6202 two years ago I proposed to replace the (somehow undocumented and only
6203 known to me) system at school by a well known Debian based system:
6204 Skolelinux.
</p
>
6206 <p
>Students and teachers appreciated the new system because of a
6207 better look and feel and an enhanced access to local media on thin
6208 clients. The possibility to alter and/or reset passwords using a GUI
6209 was welcomed, too. Being able to do administrative tasks using a GUI
6210 and to easily set up workstations using PXE was of very high value for
6211 the admin teachers.
</p
>
6213 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
6214 Edu?
</strong
></p
>
6216 <p
>It
's open source, easy to set up, stable and flexible due to it
's
6217 Debian base. It integrates LTSP out-of-the-box. And it is documented!
6218 So it was a perfect choice.
</p
>
6220 <p
>Being open source, there are no license problems and so it
's
6221 possible to point teachers and students to programs like
6222 OpenOffice.org, ViewYourMind (mind mapping) and The Gimp. It
's of
6223 high value to be able to adapt parts of the system to special needs of
6224 a school and to choose where to get support for this.
</p
>
6226 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
6227 Edu?
</strong
></p
>
6229 <p
>Nothing yet.
</p
>
6231 <p
><strong
>Which free software do you use daily?
</strong
></p
>
6233 <p
>At home (Debian Sid with Gnome Desktop): Iceweasel, LibreOffice,
6234 Mutt, Gedit, Document Viewer, Midnight Commander, flpsed (PDF
6235 Annotator). At school (Skolelinux Lenny): Iceweasel, Gedit,
6236 LibreOffice.
</p
>
6238 <p
><strong
>Which strategy do you believe is the right one to use to
6239 get schools to use free software?
</strong
></p
>
6241 <p
>Some time ago I thought it was enough to tell people about it. But
6242 that doesn
't seem to work quite well. Now I concentrate on those more
6243 interested and hope to get multiplicators that way.

6261 <p
>Det er store forskjeller på skolenes digitale tilstand, viser
6262 undersøkelsen Monitor
2011 som er laget på oppdrag fra
6263 Kunnskapsdepartementet. Dette har ført til debatt om PC-tilgangen i
6264 skolen, og om de med Linux i skolen gjør det bedre bedre eller
6265 dårligere enn snittet i landet.
</p
>
6267 <p
>Nå har vi tallene. Skoler med Linux har
36% større PC-tetthet en
6268 landsgjennomsnittet. På spørsmål hvorfor skoler med Linux har større
6269 PC-tetthet, observerer Paul Reidar Løsnesløkken som er IKT-konsulent i
6270 Nord-Odal:
</p
>
6272 <p
><blockquote
>"Vi erfarer at klienter med Skolelinux har god funksjon
6273 til de er
8 til
10 år gamle. Dette er omtrent dobbelt så lenge som
6274 andre løsninger, og skolene får mer datautstyr for
6275 pengene.
"</blockquote
></p
>
6277 <p
>Undersøkelsen baserer seg på
56 skoler som har gjort det offentlig
6278 at de kjører Skolelinux eller annen Linux-utgave. De kan også ha PC-er
6279 med Windows i skolenettet. Når en sammenligner PC-tetthetene på
6280 skolene i kommunene Flora, Harstad, Kongsvinger, Narvik, Nittedal,
6281 Nord-Odal og Randaberg, er det i snitt
2,
28 elev pr. PC på skolene med
6282 Linux. På landsbasis er det
3.11 elev per PC i grunnskolen, i følge
6283 side
95 i Monitor-rapporten for
2011. Målingen viser dermed
36% større
6284 PC-tetthet i skoler med Linux.

6288 <p
>Skolelinux har til hensikt å gi alle barn full tilgang til
6289 skoleaktuelle dataprogram på sitt eget morsmål. Derfor følger det med
6290 godt over
100 skoleaktuelle programmene laget for læring. De fleste
6291 programmene er oversatt til over
50 språk. Elevene skal også kunne
6292 studere alle sider av dataprogrammene. Derfor følger også kildekode
6293 med. Elever med interesse kan lære av eksperter som har laget
6294 systemet. Dette med enkelt programmering i læreprogram som KTurtle,
6295 til profesjonelle verktøy som Qt Creator eller Java.
</p
>
6297 <p
>Skolelinux er laget for sentralisert drift, der alt teknisk
6298 administrasjon av alle skolene kan gjøres sentralt fra kommunehuset
6299 eller sentralt i en region. F.eks. drifter to-tre personer
70.000
6300 skoledatamaskiner på
200 skoler i delstaten Extremadura i
6301 Spania. Etter velykket bruk av Debian Edu i skolen, legger delstaten
6302 over til Debian på
40.000 datamaskiner i administrasjonen. Det er idag
6303 mange selskap som tilbyr profesjonell støtte til innføring og drift i
6304 Norge og verden.

6341 <description><p
>I serien med intervjuer av folk i
6342 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet, får vi
6343 denne gangen høre fra en IKT-ansvarlig som har brukt Skolelinux i
6344 mange år, og vært storfornøyd med erfaringene så langt.
</p
>
6346 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
6348 <p
>Mitt navn er Roy-Arne Myhre og jeg er
42 år. Jeg er ansatt hos
6349 <a href=
"http://www.sandskole.no/
">Sand skole
</a
> (Balsfjord kommune)
6350 og har stort sett vært det siden
1990. Jeg er IKT ansvarlig ved
6351 skolen i
40% stilling –
10% undervisning – musikk.
</p
>
6353 <p
>Ved skolen er det ca
100 elever og ca
18 lærere +
4 assistenter i
6354 hele og delte stillinger. Alle lærerne har bærbar PC (dessverre med
6355 Win Vista) – assistenter har tilgang til egne. Vi benytter Fronter i
6356 det daglige arbeidet. Vi har ca
90 elevmaskiner som fungerer til
6357 daglig opp mot Linux server (XFCE) som driftes av
6358 <a href=
"http://www.bzz.no/
">BzzWare AS
</a
> via nett. Maskinparken
6359 består kun av brukt utstyr for elevene – og noe av dette begynner å
6360 bli vel gammelt selv som halvtykke klienter.
</p
>
6362 <p
><strong
>Hvordan kom du i kontakt med
6363 Skolelinux-prosjektet?
</strong
></p
>
6365 <p
>Vi kom første gang i kontakt med Skolelinux rundt
1997. Den gang
6366 var det oppstart-disketter i hver maskin, ikke mulighet for lyd og
6367 video, gamle nettverkskort og mye plundring. Vi hadde en ihuga
6368 forelder med som pådriver, forsker og inspirator for hele opplegget.
6369 Selv ante jeg knapt at Skolelinux fantes, men han var av den
6370 utforskende typen, og fikk både meg og skolelederen i trua på at dette
6371 var ting som kunne fungere. Etter dette har det gått gradvis
6372 framover; flere maskiner er hentet inn gjennom bl.a
6373 <a href=
"http://www.greentech.no/
">Greentech
</a
> og utrangert utstyr
6374 fra høgskole / Avinor og private givere. Når maskinene ble for trege
6375 for nye Windows-versjoner, sto vi klare til å putte dem i nettverket
6376 vårt. Dette betyr at vi i dag har
1:
1 dekning av maskiner på
6377 ungdomstrinnet og bedre enn
1:
2 på barnetrinnet. Dette er vi veldig
6378 fornøyd med, og vi kan ikke se for oss hverdagen som ville vært
6379 alternativet ved bruk av Windows med sine lisenser pr. Bruker/maskin.
6380 Da ville vi nok vært tilbake til
1-
2 maskiner pr klasserom med de
6381 negative konsekvenser det ville hatt for undervisningsformene våre. Vi
6382 kan ha en hel klasse i prosjektjobbing eller individuell jobbing
6383 samtidig – vi kan avholde tentamen og eksamen uten
6384 logistikkproblemer.
</p
>
6386 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6388 Hvor skal jeg begynne... Stabiliteten er et nøkkelord - det bare
6389 virker. Har du først fått en server med Skolelinux opp og gå, så må
6390 det en maskinarefeil eller sabotasje til for å stoppe den. Det at man
6391 kan bruke eldre maskiner som normalt sett ville gått på dynga, er også
6392 glimrende - billig for skoler med dårlig økonomi og bra for miljøet
6393 siden vi gjenbruker utstyr i stedet for å skaffe nytt. Vi ville aldri
6394 hatt mulighet til å operere med det maskinantallet vi har pr i dag
6395 hvis det ikke var for Skolelinux - så tilgjengelighet er et annet
6396 nøkkelord. Et tredje moment er sikkerhet og brukertilgang. Alle
6397 brukerer opererer med egne brukernavn og passord, samt egne
6398 brukerområder som kan tilpasses for både enbrukertilgang og for
6399 samarbeid med andre.
6401 Elever har godt av å se at det finnes andre alternativer enn de som
6402 storindustrien selger på lisensbasis - på den måten trenes de opp til
6403 å se flere muligheter og å foreta valg ut fra flere opsjoner.
6405 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6407 <p
>Ulempene med Skolelinux er nok utbredelsen og mangelen på kjennskap
6408 til dette i skolenorge. De som skal ta økonomiske avgjørelser rynker
6409 på nesen og vil gå for det kjente og «sikre» selv om det koster mye
6410 mer. Man får rett og slett litt hetta av å ikke kunne noe – og unngår
6411 dette for enhver pris.
</p
>
6413 <p
>I tillegg er mye av linux-systemet administrert av tekstkommandoer
6414 og er lite intuitiv/visuell for oss som ikke er «inne i»
6415 kildekodene». Så problemet er nok mye godt at de som
6416 utarbeider/drifter Skolelinux ikke helt klarer å sette seg ned på
6417 skoleadministratorens nivå når det gjelder problemer og
6418 utfordringer. Men dette er nok en utfordring alle administratorer
6419 sliter med uansett OS.
</p
>
6421 <p
>Derfor har vi valgt å støtte oss til BzzWare AS for assistanse i
6422 drifta slik at jeg har kunnet konsentrere meg mer om kabling, skifting
6423 av komponenter, veiledning av lærere og elever, vedlikehold av
6424 skrivere og annen daglig drift.
</p
>
6426 <p
>Elevene mestrer Skolelinux helt fint. Så lenge Internett
6427 (Iceweasel) og Libreoffice (Openoffice) fungerer er
90% av
6428 skolehverdagen velfungerende. I tillegg brukes jo en del av den
6429 pedagogiske programpakken bla. i forhold til matematikk og geografi,
6430 men det er såpass mye bra på nett om dagen, så disse programmene er
6431 mer som krydder å regne.
</p
>
6433 <p
>Jeg skulle ønske neste versjon av Skolelinux kunne komme litt
6434 mindre stappet med programmer, for halvparten blir aldri brukt, eller
6435 fungerer ikke uansett. Hva med et pedagogisk panel av lærere/IKT
6436 ansvarlige som kunne sagt: disse programmene skal være standard, så
6437 får resten være slike man kan legge til ved behov – det kan lett bli
6438 en jungel å bevege seg i.
</p
>
6440 <p
>Jeg ønsker meg også en mer grafisk versjon av
6441 <a href=
"http://bzz.no/lwat/trac/trac.cgi
">Lwat
</a
> hvor man kan krysse
6442 ut de som f.eks ikke skal ha internett-tilgang en dag pga
6443 eksamen/tentamen, samt en noe enklere brannmurløsning hvor man kan
6444 stenge for en del (få) sider på en enkel måte. Jeg liker godt
6445 Skolelinux sin ideologi om at filteret skal trenes i hodet på eleven –
6446 men av og til skulle jeg ønske at f.eks Facebook og Youtube kunne vært
6447 koblet vekk en periode for å få bedre utnyttelse av tid og
6448 ressurser. Disse to nettstedene er nok mye av årsaken til at mange
6449 lærere holder igjen databruken noe mer enn man kunne ønske.
</p
>
6451 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
6453 Jeg benytter nesten bare fri programvare til daglig. LibreOffice,
6454 Iceweasel (Firefox), Thunderbird til e-post og Gimp til
6455 bildebehandling. Vi har PHP-Nuke-oppsatt hjemmeside. Det eneste som
6456 jeg ikke har fått helt til enda er videoredigering - her må man vel
6457 innrømme at Mac er hakket over, men da er vi igjen over på å se hva
6458 som egner seg best, og ta valg ut fra det. Folk flest lever i
6459 villfarelsen om at regneark HETER Excel og tekstbehandling HETER
6460 Word. Dette er en misforståelse som jeg bruker mye energi på å
6461 diskutere og
"åpne sinn
" på Microsoft-slaver. Dessverre er det mange
6462 IKT-ansvarlige som også har låst seg på at det eneste saliggjørende er
6463 Bill G sine produkter.
6465 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
6466 skoler til å ta i bruk fri programvare?
</strong
></p
>
6468 <p
>For å komme lenger i utbredelsen av Skolelinux tror jeg det må mer
6469 fram i nasjonale medier, samt komme bedre fram hva økonomien i dette
6470 valget vil være – samt mulighetene. Fri programvare er en berikelse og
6471 gjør oss i stand til å utføre arbeidet i skolen uten å måtte legge
6472 igjen tusener på tusener i Bill Gates lomme.. Få ETT nettsted med
6473 forståelig veiledning av installasjon/oppgradering og ETT forum med
6474 konkrete feilrettinger og problemer, så tror jeg vi kunne kommet et
6475 par skritt framover. Ellers tror jeg bare at ildsjelene må fortsette å
6476 skinne – kanskje flere enn oss følger etter på veien.

>Den siste uka har det vært en del skriverier om hvor store
6511 forskjeller det er mellom skolene når det gjelder digital kompetanse.
6513 <a href=
"http://www.digi.no/
891660/bekymret-for-it-i-skolen
">oppslaget
6514 i Digi
</a
>. Diskusjonen fikk meg til å bli litt nysgjerrig på om
6515 Linux-skoler har større PC-tettet enn snittet i landet. Grunnlaget
6516 for diskusjonen har vært undersøkelsen
6517 <a href=
"https://iktsenteret.no/ressurser/monitor-
2011-skolens-digitale-tilstand
">Monitor
6518 2011</a
>, som bruker informasjon fra
6519 <a href=
"https://www.wis.no/gsi
">Grunnskolens Informasjonssystem
</a
>
6520 (GSI). GSI-data kan lastes ned fra web og jeg lastet ned en Excel-fil
6521 (intet åpen standard-valg tilgjengelig) med navn på alle skoler,
6522 hvilke kommune de befinner seg i og hvor mange elever pr. elev-PC de
6523 har rapportert inn. For å få en ide om svaret trenger jeg deretter å
6524 vite hvilke skoler i landet som bruker Linux, slik at jeg kan slå dem
6525 opp i GSI og finne ut hvor stor PC-tetthet de har.
</p
>
6527 <p
>Jeg vet om skoler i Balsfjord, Flora, Harstad, Kongsvinger, Narvik,
6528 Nittedal, Nord-Odal, Randaberg og Sunndal som bruker Skolelinux eller
6529 andre Linux-varianter. Jeg tror det er flere enn de
56 skolene jeg
6530 har klart å identifisere de siste dagene, men har ikke klart å få det
6531 bekreftet med offentlige kilder.
</p
>
6533 <p
>Monitor
2011-rapporteres side
95 forteller at det
"ifølge GSI
6534 (
20120-
2011) er det
3,
11 elever per datamaskin når vi tar med alle
6535 grunnskoler (
1.-
10.trinn)
". For de
56 Linux-skolene jeg har klart å
6536 koble mot informasjon i GSI er det
2,
28 elever per elevdatamaskin,
6537 hvilket betyr at det er
36% høyere PC-tetthet på Linux-skoler enn
6538 landsgjennomsnittet. Linux-skolen med høyest tettet blant de jeg har
6539 notert -skole er Flora ungdomsskule i Flora kommune med
0.82 elev
6540 pr. PC (
482 elever,
588 elevdatamaskiner).
</p
>
6542 <p
>Skolelinux gir datamaskiner lengre levetid, og en kan dermed få
6543 flere operative datamaskiner for samme budsjett, i tillegg til en
6544 rekke andre fordeler. Kan det være forklaringen på forskjellen?
</p
>
6546 <p
>Tallene må tas med en liten klype, da GSI ser ut til å ha endel
6547 feilføringer. Jeg synes i hvert fall en skole med
423 elever og
9
6548 elevmaskiner ser mistenkelig ut. Eller en skole med
346 elever,
0
6549 elevmaskiner, som er et annet ekstremt eksempel jeg fant.

</p

6567 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
6569 <p
>I teach ICT part time at the Rudolf Steiner School in Kings
6570 Langley, near London, UK. Previously I worked as a technical
6571 author/trainer while my children attended the school, and I also
6572 contributed to the Schoolforge UK community with the aim of
6573 encouraging UK schools to adopt free/open source software. Five or six
6574 years ago we had about
50 schools interested in some way, but we
6575 weren
't able to convert many of them into sustainable
6576 installations.
</p
>
6578 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
6579 project?
</strong
></p
>
6581 <p
>Skolelinux had two representatives at an early Edubuntu meeting in
6582 London which I attended. However at that time our school network had
6583 just been installed using CentOS, LTSP
4 and GNOME. When LTSP
5 came
6584 along we switched to Edubuntu thin client servers so now we have a
6585 mixed environment which includes Windows PCs and student laptops, as
6586 well as their MacBooks and iPads. However, the proprietary systems
6587 have always been rather problematic, and we never built a GUI for the
6588 LDAP server, so when I discovered Skolelinux is configured for all
6589 these things we decided to try it.
</p
>
6591 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
6592 Edu?
</strong
></p
>
6594 <p
>By far the biggest advantage is the Debian Edu community. Apart
6595 from that I have always believed in the same
"sustainable computing
"
6596 goals that Skolelinux is built on: installing Linux on computers which
6597 would otherwise be thrown away, to provide a reliable, secure and
6598 low-cost IT environment for schools. From my own experience I know
6599 that a part-time person can teach and manage a network of about
25
6600 Linux computers, but it would take much more of my time if we had
6601 proprietary software everywhere.
</p
>
6603 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
6604 Edu?
</strong
></p
>
6606 <p
>As a newcomer I
'm just finding out who
's who in the community and
6607 how you
're organised, and what your procedures are for dealing with
6608 various things such as editing manual pages and so-on. The only
6609 English language mailing list seems to be for developers as well as
6610 users, so my inbox needs heavy pruning each day!
</p
>
6612 <p
><strong
>Which free software do you use daily?
</strong
></p
>
6614 <p
>Besides the software already mentioned at school we use Samba,
6615 OpenLDAP, CUPS, Nagios and Dansguardian for the network, and on the
6616 desktops we have LibreOffice, Firefox, GIMP and Inkscape. At home I
6617 use Ubuntu and an Android
4 eePad Transformer (but I
'm not sure if
6618 that counts...)
</p
>
6620 <p
><strong
>Which strategy do you believe is the right one to use to
6621 get schools to use free software?
</strong
></p
>
6623 <p
>That
's a tough question! For very many years UK schools installed
6624 and taught only proprietary software, so that at the highest levels
6625 the notion of
"computer
" means simply
"proprietary office
6626 applications
". However, schools today are experiencing budget
6627 constraints, and many are having to think hard about upgrading Windows
6628 XP. At the same time, we have students showing teachers how to use
6629 iPads, MacBooks and Android, so the choice of operating system is no
6630 longer quite so automatic. What is more, our government at last
6631 realised that we need people with programming skills, so they
're
6632 putting coding back in the curriculum! And it
's encouraging that the
6633 first
10,
000 Raspberry Pi units sold out in
2 hours.
</p
>
6635 <p
>I don
't really know what strategy is going to get UK schools to use
6636 free software, but building an active community of Skolelinux/Debian
6637 Edu users in this country has to be part of it.

>Documentation in Debian Edu is provided in several languages, and
6647 it is important to make it both easy to contribute and to keep the
6648 translated versions in sync. To do this we have come up with what we
6649 believe is a very efficient work flow.
</p
>
6653 <li
>The documentation is written in a
6654 <a href=
"http://moinmo.in
">moinmoin wiki
</a
> (see for example
6655 <a href=
"http://wiki.debian.org/DebianEdu/Documentation/Squeeze
">the
6656 Squeeze release manual
</a
>) with support for exporting the content as
6657 docbook XML.
</li
>
6659 <li
>This docbook document is given to po4a to extract a gettext style
6660 .pot file with the content, which in turn is used to create .po files
6661 with the translated text.
</li
>
6663 <li
>The .po files are given to translators, and they can always tell
6664 which part of the original wiki document is new or changed. They can
6665 use their normal translation tools like lokalize or poedit to write
6666 the translation. There is even a system in place to handle translated
6669 <li
>The translated .po files are combined with the original docbook
6670 XML document using po4a to create a translated docbook document.
</li
>
6672 <li
>The final step is to use all the generated docbook files and
6673 create PDF and HTML version of the original and translated documents.
</li
>
6677 <p
>This setup work very well, but have a few issues. The biggest
6678 issue is that
<a href=
"http://moinmo.in/DocBook
">the docbook support
6679 we use in moinmoin
</a
> is not actively maintained. The docbook
6680 support is also buggy, and our build system contain workarounds to
6681 make sure the generated docbook is usable despite these bugs.
</p
>
6683 <p
>If you want to have a look at our setup, it is all there in the

6740 <p
>Jeg hørte om det først når jeg jobbet i Redpill Linpro. Men jeg
6741 har også en datter som går på en friskole, som også bruker Skolelinux.
6742 Som kjent har ikke friskoler de samme økonomiske rammebetingelsene som
6743 offentlige skoler, så for dem var det det absolutt beste alternativet.
6744 De anser også Skolelinux som et stabilt system, som bare går og går (i

6750 <p

6751 lydløse og raskere arbeidsstasjoner som er bedre i klasserommet.
6752 Lengre levetid på PC
'er. Store besparelser på maskinvare og drift. Og
6753 så klart fjerning av alle lisenskostnader. Personlig synes jeg også at
6754 mange av programmene er bedre enn alternativene. Men dette er ofte en
6755 smakssak og avhengig om man må ha det man er vant til fra før.

6760 kompatibilitet med arbeidsstasjoners/bærbare maskiner sine
6761 nettverksdrivere eller skjermkort. Men dette løser vi i skolene ved
6762 standardisering. Ellers er det få, om nesten ingen, av de kjente
6763 maskinvare / infrastruktur leverandørene til fylkes- / kommuner som
6764 tilbyr denne plattformen. Skal dette endre seg så må kommunene selv
6765 sette slike krav til leverandørene.

6769 <p
>Har brukt OpenOffice.org siden starten (

6770 desktop siden
2005. Bruker i dag Kubuntu, Libreoffice og ymse annet
6771 programvare til ulik kontorbruk som er lett å installere / teste via

>
6777 <p
>Fortsette å presentere flere av de gode eksemplene hvor Debian Edu
6778 / Skolelinux brukes i kommuner og enkeltskoler. Vi må få bedre frem
6779 at det er mulig tilknytte både Windows og Mac klienter på denne
6780 plattformen (selv om det vil øke driftskostnadene). Dette gjøres
6781 mange steder. Spesielt er det mange lærere som ønsker å bruke
6782 Windows/Mac-bærbare, gjerne som sin private PC også. Det er også mulig
6783 for kommunen å integrere med Active Directory i stedet for OpenLDAP
6784 som kommer med ut av boksen (selv om også dette øker kostnadene).
6785 Dette vil muligens bidra til å fjerne noe motstand hos noen
6786 potensielle brukere / driftpersonell for å ta i bruk noe
6787 nytt. Fremveksten av mobile brukere og nettbrett går i vår favør.
6788 Brukerne blir kjent og vant til flere nye operativsystemer /
6789 brukergrensesnitt. Så utviklerfellesskapet bør jobbe videre med å
6790 integrere flere nye klienttyper, som ultra lav-kostklienter og
6791 nettbrett (blant annet fri programvare-alternativet

6826 more international audience.

6828 <p
>While
<a href=
"http://www.skolelinux.org/
">Debian Edu and
6829 Skolelinux
</a
> originated in France and Norway, and have most users in
6830 Europe, there are users all around the globe. One of those far away
6831 from me is Nigel Barker, a long time Debian Edu system administrator
6832 and contributor. It is thanks to him that Debian Edu is adjusted to
6833 work out of the box in Japan. I got him to answer a few questions,
6834 and am happy to share the response with you. :)
6837 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
6839 <p
>My name is Nigel Barker, and I am British. I am married to Yumiko,
6840 and we have three lovely children, aged
15,
14 and
4(!) I am the IT
6841 Coordinator at Hiroshima International School, Japan. I am also a
6842 teacher, and in fact I spend most of my day teaching Mathematics,
6843 Science, IT, and Chemistry. I was originally a Chemistry teacher, but
6844 I have always had an interest in computers. Another teacher teaches
6845 primary school IT, but apart from that I am the only computer person,
6846 so that means I am the network manager, technician and webmaster,
6847 also, and I help people with their computer problems. I teach python
6848 to beginners in an after-school club. I am way too busy, so I really
6849 appreciate the simplicity of Skolelinux.
</p

6851 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
6852 project?
</strong
></p
>
6854 <p
>In around
2004 or
5 I discovered the ltsp project, and set up a
6855 server in the IT lab. I wanted some way to connect it to our central
6856 samba server, which I was also quite poor at configuring. I discovered
6857 Edubuntu when it came out, but it didn
't really improve my setup. I
6858 did various desperate searches for things like
"school Linux server
"
6859 and ended up in a document called
"Drift
" something or other. Reading
6860 there it became clear that Skolelinux was going to solve all my
6861 problems in one go. I was very excited, but apprehensive, because my
6862 previous attempts to install Debian had ended in failure (I used
6863 Mandrake for everything - ltsp, samba, apache, mail, ns...). I
6864 downloaded a beta version, had some problems, so subscribed to the
6865 Debian Edu list for help. I have remained subscribed ever since, and
6866 my school has run a Skolelinux network since Sarge.
</p

6868 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
6869 Edu?
</strong
></p
>
6871 <p
>For me the integrated setup. This is not just the server, or the
6872 workstation, or the ltsp. Its all of them, and its all configured
6873 ready to go. I read somewhere in the early documentation that it is
6874 designed to be setup and managed by the Maths or Science teacher, who
6875 doesn
't necessarily know much about computers, in a small Norwegian
6876 school. That describes me perfectly if you replace Norway with
6879 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
6880 Edu?
</strong
></p
>
6882 <p
>The desktop is fairly plain. If you compare it with Edubuntu, who
6883 have fun themes for children, or with distributions such as Mint, who
6884 make the desktop beautiful. They create a good impression on people
6885 who don
't need to understand how to use any of it, but who might be
6886 important to the school. School administrators or directors, for
6887 instance, or parents. Even kids. Debian itself usually has ugly
6888 default theme settings. It was my dream a few years back that some
6889 kind of integration would allow Edubuntu to do the desktop stuff and
6890 Debian Edu the servers, but now I realise how impossible that is. A
6891 second disadvantage is that if something goes wrong, or you need to
6892 customise something, then suddenly the level of expertise required
6893 multiplies. For example, backup wasn
't working properly in Lenny. It
6894 took me ages to learn how to set up my own server to do rsync backups.
6895 I am afraid of anything to do with ldap, but perhaps Gosa will
6898 <p
><strong
>Which free software do you use daily?
</strong
></p
>
6900 <p
>Nowadays I only use Debian on my personal computers. I have one for
6901 studio work (I play guitar and write songs), running AV Linux
6902 (customised Debian) a netbook running Squeeze, and a bigger laptop
6903 still running Skolelinux Lenny workstation. I have a Tjener in my
6904 house, that
's very useful for the family photos and music. At school
6905 the students only use Skolelinux. (Some teachers and the office still
6906 have windows). So that means we only use free software all day every
6907 day. Open office, The GIMP, Firefox/Iceweasel, VLC and Audacity are
6908 installed on every computer in school, irrespective of OS. We also
6909 have Koha on Debian for the library, and Apache, Moodle, b2evolution
6910 and Etomite on Debian for the www. The firewall is Untangle.
</p
>
6912 <p
><strong
>Which strategy do you believe is the right one to use to
6913 get schools to use free software?
</strong
></p
>
6915 <p
>Current trends are in our favour. Open source is big in industry,
6916 and ordinary people have heard of it. The spread of Android and the
6917 popularity of Apple have helped to weaken the impression that you have
6918 to have Microsoft on everything. People complain to me much less about
6919 file formats and Word than they did
5 years ago. The Edu aspect is
6920 also a selling point. This is all customised for schools. Where is the
6921 Windows-edu, or the Mac-edu? But of course the main attraction is
6922 budget.The trick is to convince people that the quality is not
6923 compromised when you stop paying and use free software instead. That
6924 is one reason why I say the desktop experience is a weakness. People
6925 are not impressed when their USB drive doesn
't work, or their browser
6926 doesn
't play flash, for example.

>Many years ago, the
<a href=
"http://www.skolelinux.org/
">Skolelinux
6973 / Debian Edu project
</a
> initiated a student project to create a tool
6974 for making stop motion movies. The proposal came from a teacher
6975 needing such tool on Skolelinux. The project, called
"stopmotion
",
6976 was manned by two extraordinary students and won a school award and a
6977 national aware with this great project. The project was initiated and
6978 mentored by Herman Robak, and manned by the students Bjørn Erik Nilsen
6979 and Fredrik Berg Kjølstad. They got in touch with people at Aardman
6980 Animation studio and received feedback on how professionals would like
6981 such stopmotion tool to work, and the end result was and is used by
6982 animators around the globe. But as is usual after studying, both got
6983 jobs and went elsewhere, and did not have time to properly tend to the
6984 project, and it has been lingering for a few years now. Until last
6987 <p
>Last year some of the users got together with Herman, and moved the
6988 project to Sourceforge and in effect restarted the project under a new
6990 <a href=
"http://sourceforge.net/projects/linuxstopmotion/
">linuxstopmotion
</a
>.
6991 The name change was done to make it possible to find the project using
6992 Internet search engines (try to search for
'stopmotion
' to see what I
6993 mean). I
've been following
6994 <a href=
"https://lists.sourceforge.net/lists/listinfo/linuxstopmotion-community
">the
6995 mailing list
</a
> and the improvement already in place and planned for
6996 the future is encouraging. If you want to make stop motion movies.

>Knut Yrvin her. Jobber i Nokia med å fremme rammeverket Qt og QML
7074 med tilhørende utviklerverktøy. Rollen er som leder av
7075 friprog-samfunn. I fjor var jeg med å legge om utviklingen av Qt til
7076 åpen forvaltning. På den måten kan alle som bidrar til Qt gjøre det
7077 på like vilkår. Nå er det

">over
7079 1000 utviklere
</a

7080 forvaltning er utviklingen av Qt mer åpen enn Linux-kjernen.
</p
>
7082 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
7084 <p
>Jeg var en av initiativtagerne til Skolelinux i
2001. Skolene slet
7085 med både utstyr og Internett-tilgang. De klarte ikke å møte
7086 forventningene til data i skolen. Driften av PC-ene var uholdbar. Som
7087 regel hadde rektor pekt ut en ivrig lærer til å passe på PC-ene,
7088 gjerne naturfaglæreren. Mange lærere jobbet mye ubetalt overtid for å
7089 vedlikeholde
30-
40 datamaskiner på hver sin skole. Med
300 elever og
7090 lærere som brukere, blir det fort mye mer arbeid enn de
4-
8 timene de
7091 kunne bruke på PC-drift. Skolene hadde kun en femtedel av
7092 IT-budsjettet som ble brukt på PC-ene i rådhuset.
</p
>
7094 <p
>Vi erfarte at skolene hadde mye datautstyr som stod ubrukt. Skolene
7095 manglet penger til Microsoft-lisenser. Selv med solide skolerabatter,
7096 kostet Microsoft-lisensene gjerne like mye som PC-ene i seg selv over
7097 en periode på
5-
6 år.
</p
>
7099 <p
>Viktigheten av språklig mangfold og pedagogiske programmer var også
7100 viktig for oss. Vi oversatte mange skoleaktuelle programmer til
7101 nynorsk, nordsamisk og bokmål. Dette lenge før andre tok denne
7102 oppgaven seriøst. Allerede etter ett år hadde vi etablert et helt
7103 arsenal av skoleaktuelle programmer på nynorsk, bokmål og
7104 nordsamisk. Vi spredde vår ide om språklig mangfold til de andre frie
7105 prosjekter internasjonalt. Resultatene ser vi i mange land. Det er de
7106 frie programmene som kommer på brukernes morsmål. Det er en av flere
7107 gode grunner til at fri programvare som LibreOffice, VLC, KDE og
7108 Firefox konkurrerer ut godseid programvare mange steder i verden.
</p
>
7110 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7112 <p
>Fordelene er at Skolelinux tilbyr over
100 skoleaktuelle programmer
7113 på de norske språkene, uten ett øre i lisenskostnader. Systemet gir
7114 enormt lave driftskostnader med diskløse arbeidsstasjoner og bærbare
7115 med roaming. Skolelinux krever også mindre av maskinvaren.
</p
>
7117 <p
>Man kan fint kjøre systemet med
512 MB RAM på en bærbar PC sammen
7118 med en nettvideo i nettleseren og en presentasjon med
7119 LibreOffice. Konkurrerende system krever fort
2 GB RAM for å få til
7120 noe tilsvarende uten at det går ufattelig tregt. Skal man gjøre noe
7121 nyttig, krever konkurrentene til Linux mye større harddisk. Skoler har
7122 rapportert at de fort har fått
50% flere nye maskiner om de velger
7123 Linux. Dette i tillegg til de årlige besparelsene ved å unngå
7124 lisensbetaling til godseid programvare.
</p
>
7126 <p
>De lave driftskostnadene gjør at delstater i Europa har titusener
7127 av datamaskiner med Skolelinux i skolen. F.eks. er det under ti
7128 personer som drifter
70.000 PC-systemer i skolene i Extremadura i
7129 Spania. Det er slett ikke uvanlig at norske kommuner har
1500-
2000
7130 datamaskiner med Skolelinux. Driften tar ett årsverk. Slår flere
7131 kommuner seg sammen, kan de få samme sentraliserte stordriftsfordeler
7132 som delstater i Tyskland og Spania. Delstater som kjører Skolelinux
7133 på alle skolene. Bare noen få personer sentraldrifter titusenvis av
7136 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7138 <p
>Den største ulempen for Skolelinux er motstand mot Linux fra
7139 IT-sjefer i det offentlige. Dette er ledere som holder innlegg som
7140 snytt ut av evangelist-håndboka til Microsoft. Dette gjøres i ett
7141 arbeidsmarked med stor vekst i etterspørselen etter Linux-fagfolk i
7142 privat sektor. Etterspørselen har økt mer enn noe annet tekniske yrke
7143 siste tiåret. Åtte av ti ledere vil ansette Linux-fagfolk i
2012,
7144 rapporterer jobbnettstedet Dice.com på oppdrag av Linux
7145 Foundation.
</p
>
7147 <p
>Det mangler
16.000 ingeniører og IKT-fagfolk i Norge rapporterte
7148 arbeids- og velferdsetaten NAV. Linux-fagfolk kan velge svært
7149 interessante jobber med alt fra apps på ledende mobilsystem laget med
7150 Linux, sky- tjenester eller web-applikasjoner. De raskest voksende
7151 teknologiselskapene i verden er ute etter Linux-fagfolk. Det være seg
7152 Amazon, Google, Facebook og IBM for å nevne noen. Linux er kritisk
7153 for å sikre veksten i markedet. Det sier seg selv at lønningene og
7154 jobbmulighetene er bedre enn for andre tekniske yrker.
</p
>
7156 <p
>Skal man lage apps for mobilen, smart-TV-en eller
7157 underholdningssystemet i bilen eller på flyet, er det Linux som
7158 gjelder. Med en slik konkurranse om Linux-kompetansen, kombinert med
7159 motstanden mot Linux hos mange IT-sjefer i offentlig sektor, så
7160 hindrer kommunene rekruttering av flere Linux- fagfolk. Skolene blir
7161 tvunget til å velge dyrere og mindre komplette IT-system. De har
7162 blitt hengende igjen slik IT var på begynnelsen av
2000- tallet. Dette
7163 fordi IT-ledere ikke har tilpasset seg markedet det siste tiåret.
</p
>
7165 <p
>Når det er sagt, er Skolelinux svært enkelt å lære seg også for de
7166 som ikke kan. Det viser alle lærerne som drifter systemet for
7167 hundrevis og tusenvis av systemer. Det meste er på plass rett ut av
7168 boksen. I tillegg er det solid med dokumentasjon med god hjelp på
7169 nettet. Det er mange kommuner som har ansatt en lærer som først lærte
7170 Skolelinux på sin skole, for så å drifte alle PC-ene i kommunen med
7171 Skolelinux. Det kan fort være snakk om
1000-
3000 datamaskiner på
10-
15
7172 skoler som sentraldriftes med en stilling. Står man ordentlig fast,
7173 kan man også kjøpe profesjonell hjelp fra selskap som støtter
7174 Skolelinux. Det er flere slike selskap i Norge og i utlandet.

7182 det bra med Skolelinux i skolen, da utvalget av programmer er

7238 stiftelsen Åpne kontorprogram på norsk for å oversette og teste den
7239 norske utgaven av OpenOffice.org. Arbeidet har hele tiden vært

7247 kunnskap med andre, og det er dette som er hovedstyrken til
7248 prosjektet. Selv om Skolelinux hovedsaklig er involvert i utvikling

7275 mulig å involvere utdanningssektoren direkte i arbeidet, for eksempel
7276 gjennom studentprosjekter der elevene selv er med å utforme
7277 programvare direkte eller indirekte gjennom aktive bidrag. Dette gjør
7278 ikke bare samarbeidet tettere, men fokuset på standarder og friheten
7279 til å velge sin egen løsning vil kanskje stimulere interessen for
7280 framtidig deltakelse i bransjen. Vi som driver med fri og åpen
7281 programvare ønsker oss ikke rene konsumenter, men tenkende og

>New in the Squeeze version of
7292 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> is the
7293 ability for clients to automatically configure their proxy settings
7294 based on their environment. We want all systems on the client to use
7295 the WPAD based proxy definition fetched from
<tt
>http://wpad/wpad.dat
</tt
>, to
7296 allow sites to control the proxy setting from a central place and make
7297 sure clients do not have hard coded proxy settings. The schools can
7298 change the global proxy setting by editing
7299 <tt
>tjener:/etc/debian-edu/www/wpad.dat
</tt
> and the change propagate
7300 to all Debian Edu clients in the network.
</p
>
7302 <p
>The problem is that some systems do not understand the WPAD system.
7303 In other words, how do one get from a WPAD file like this (this is a
7304 simple one, they can run arbitrary code):
</p
>
7306 <blockquote
><pre
>
7307 function FindProxyForURL(url, host)
7309 if (!isResolvable(host) ||
7310 isPlainHostName(host) ||
7311 dnsDomainIs(host,
".intern
"))
7312 return
"DIRECT
";
7314 return
"PROXY webcache:
3128; DIRECT
";
7316 </pre
></blockquote
>
7318 <p
>to a proxy setting in the process environment looking like this:
</p
>
7320 <blockquote
><pre
>
7321 http_proxy=http://webcache:
3128/
7322 ftp_proxy=http://webcache:
3128/
7323 </pre
></blockquote
>
7325 <p
>To do this conversion I developed a perl script that will execute
7326 the javascript fragment in the WPAD file and return the proxy that
7328 <tt
><a href=
"http://www.debian.org/
">http://www.debian.org/
</a
></tt
>,
7329 and insert this extracted proxy URL in
<tt
>/etc/environment
</tt
> and
7330 <tt
>/etc/apt/apt.conf
</tt
>. The perl script wpad-extract work just
7331 fine in Squeeze, but in Wheezy the library it need to run the
7332 javascript code is
<a href=
"http://bugs.debian.org/
631045">no longer
7333 able to build
</a
> because the C library it depended on is now a C++
7334 library. I hope someone find a solution to that problem before Wheezy
7335 is frozen. An alternative would be for us to rewrite wpad-extract to
7336 use some other javascript library currently working in Wheezy, but no
7337 known alternative is known at the moment.
</p
>
7339 <p
>This automatic proxy system allow the roaming workstation (aka
7340 laptop) setup in Debian Edu/Squeeze to use the proxy when the laptop
7341 is connected to the backbone network in a Debian Edu setup, and to
7342 automatically use any proxy present and announced using the WPAD
7343 feature when it is connected to other networks. And if no proxy is
7344 announced, direct connections will be used instead.
</p
>
7346 <p
>Silently using a proxy announced on the network might be a privacy
7347 or security problem. But those controlling DHCP and DNS on a network
7348 could just as easily set up a transparent proxy, and force all HTTP
7349 and FTP connections to use a proxy anyway, so I consider that
7350 distinction to be academic. If you are afraid of using the wrong
7351 proxy, you should avoid connecting to the network in question in the
7352 first place. In Debian Edu, the proxy setup is updated using dhcp and
7353 ifupdown hooks, to make sure the configuration is updated every time
7354 the network setup changes.
</p
>
7356 <p
>The WPAD system is documented in a
7357 <a href=
"http://tools.ietf.org/html/draft-ietf-wrec-wpad-
01">IETF
7358 draft

7388 med brukte jeg først Mandrake og så Debian. Og siden jeg oppdaget at

7406 svare så detaljert rundt ulempene med Skolelinux. Hovedårsaken til at
7407 jeg bruker Kubuntu er nok at da vi begynte med det mener jeg det ikke
7408 var noen annen løsning. «Vandrende arbeidsstasjon» mener jeg ikke
7409 fantes da. Dessuten ville jeg ha siste versjon, da den KDE-versjonen
7410 som var i Skolelinux den gangen var en god del enklere (tror det var

>Since the Lenny version of
7451 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>, a
7452 feature to save power have been included. It is as simple as it is
7453 practical: Shut down unused clients at night, and turn them on again
7454 in the morning. This is done using the
7455 <a href=
"http://packages.qa.debian.org/s/shutdown-at-night.html
">shutdown-at-night
</a
> Debian package.
</p
>
7457 <p
>To enable this feature on a client, the machine need to be added to
7458 the netgroup shutdown-at-night-hosts. For Debian Edu, this is done in
7459 LDAP, and once this is in place, the machine in question will check
7460 every hour from
16:
00 until
06:
00 to see if the machine is unused, and
7461 shut it down if it is. If the hardware in question is supported by
7463 <a href=
"http://packages.qa.debian.org/n/nvram-wakeup.html
">nvram-wakeup
</a
>
7464 package, the BIOS is told to turn the machine back on around
07:
00 +-
7465 10 minutes. If this isn
't working, one can configure wake-on-lan to
7466 try to turn on the client. The wake-on-lan option is only documented
7467 and not enabled by default in Debian Edu.
</p
>
7469 <p
>It is important to not turn all machines on at once, as this can
7470 blow a fuse if several computers are connected to the same fuse like
7471 the common setup for a classroom. The nvram-wakeup method only work
7472 for machines with a functioning hardware/BIOS clock. I
've seen old
7473 machines where the BIOS battery were dead and the hardware clock were
7474 starting from
0 (or was it
1990?) every boot. If you have one of
7475 those, you have to turn on the computer manually.
</p
>
7477 <p
>The shutdown-at-night package is completely self contained, and can
7478 also be used outside the Debian Edu environment. For those without a
7479 central LDAP server with netgroups, one can instead touch the file
7480 <tt
>/etc/shutdown-at-night/shutdown-at-night
</tt
> to enable it.
7481 Perhaps you too can use it to save some power?

7512 <li

7513 disabled queues are restarted every hour. This should cut down on
7514 the amount of manual administration needed for printers.
</li
>
7516 <li
>The set of initial users have been changed. Now a personal user
7517 for the local system administrator is created during installation
7518 instead of the previously created localadmin and super-admin users,
7519 and this user is granted administrative privileges using group
7520 membership. This reduces the number of passwords one need to keep
7521 up to date on the system.

7546 on Squeeze, we provide several scripts and modifications to make
7547 firmware blobs easier to handle. The common use case I run into is a
7548 laptop with a wireless network card requiring non-free firmware to
7549 work, but there are other use cases as well.
</p

7551 <p
>First and foremost, Debian Edu provide ISO images for DVD and CD
7552 with all firmware packages in the Debian sections main and non-free
7553 included, to ensure debian-installer find and can install all of them
7554 during installation. This take care firmware for network devices used
7555 by the installer when installing from from local media. But for
7556 example multimedia devices are not activated in the installer and are
7557 not taken care of by this.

7559 <p

7562 firmware. The firmware file name is looked up in the Contents-ARCH.gz
7563 file available in the package repository, and the packages providing

7646 <description><p
>The next version of
<a href=
"http://www.skolelinux.org/
">Debian Edu
7647 / Skolelinux
</a
> will include a new tool
7648 <tt
>sitesummary2ldapdhcp
</tt
>, which can be used to quickly set up all
7649 the computers in a school without much manual labour. Here is a short
7650 summary on how to use it to set up a new school.
</p
>
7652 <p
>First, install a combined Main Server and Thin Client Server as the
7653 central server in the network. Next, PXE boot all the client machines
7654 as thin clients and wait
5 minutes after the last client booted to
7655 allow the clients to report their existence to the central server. When
7656 this is done, log on to the central server and run
7657 <tt
>sitesummary2ldapdhcp -a
</tt
> in the
<tt
>konsole
</tt
> to use the
7658 collected information to generate system objects in LDAP. The output
7659 will look similar to this:
</p
>
7661 <p
><blockquote

>

7669 enter password: *******
7671 </pre
></blockquote
></p
>
7673 <p
>After providing the LDAP administrative password (the same as the
7674 root password set during installation), the LDAP database will be
7675 populated with system objects for each PXE booted machine with
7676 automatically generated names. The final step to set up the school is
7677 then to log into
<a href=
"https://oss.gonicus.de/labs/gosa/
">GOsa
</a
>,
7678 the web based user, group and system administration system to change
7679 system names, add systems to the correct host groups and finally
7680 enable DHCP and DNS for the systems. All clients that should be used
7681 as diskless workstations should be added to the workstation-hosts
7682 group. After this is done, all computers can be booted again via PXE
7683 and get their assigned names and group based configuration
7684 automatically.
</p
>
7686 <p
>We plan to release beta3 with the updated version of this feature
7687 enabled this weekend. You might want to give it a try.
</p
>
7689 <p
>Update
2012-
01-
28: When calling sitesummary2ldapdhcp to add new
7690 hosts, one need to add the option -a. I forgot to mention this in my
7691 original text, and have added it to the text now.

>I serien med intervjuer av folk i
7701 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet, har jeg nå
7702 lyktes med å få tak i en skolemann som ikke er aktiv med utviklingen,
7703 men likevel har vært med nesten siden starten av prosjektet. Jeg
7704 ønsker derfor velkommen til Paul Reidar Løsnesløkken, en mann med
7705 mange års erfaring i bruk av Skolelinux.
</p
>
7707 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
7709 <p
>Jeg driftet tidligere IKT løsningen for skolene i
7710 <a href=
"http://www.nord-odal.kommune.no/
">Nord-Odal
</a
>. I dag er jeg
7711 IKT-konsulent for hele kommunen og samarbeider med
7712 <a href=
"http://www.hedmarken-ikt.no/
">Hedmark-IKT
</a
> for best mulig
7713 tjenester til kommunen. Jeg har bakgrunn som elektronikkreparatør og
7714 grunnskolelærer og har tatt en del fag innen IKT, i hovedsak
7715 driftsfag. IKT i Nord-Odal kommune blir i dag driftet av Hedmark IKT
7716 som er et samarbeid mellom Løten, Stange, Grue, Hamar, Kongsvinger og
7717 Nord-Odal. Jeg er fortsatt
"IKT-personen
" på skolene i kommunen og
7718 følger opp og gjør enkelte mindre endringer der.
</p
>
7720 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
7722 <p
>Kommunen satset på Skolelinux i
2004. Jeg var ikke med i
7723 beslutningsprosessen den gang, men ble likevel med fra starten når
7724 dette ble levert.
</p
>
7726 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7728 <p
>Fordelene med Skolelinux er rask oppstart, sentral drift av
7729 klientene, klienter som jobber raskt og effektivt, bedre
7730 funksjonalitet på eldre utstyr og en ganske god programpakke med fri
7731 programvare som følger med. Løsningen med halvtykke klienter gjør at
7732 prosessering skjer lokalt med alltid ferske maskiner.
</p
>
7734 <p
>Skolelinux kan fungere godt på gammelt utstyr, men det er klart at
7735 utstyr også blir for gammelt selv for Skolelinux. I forbindelese med
7736 at vi nylig fikk nye servere og ny installasjon kastet jeg ut ca
60
7737 klienter som fortsatt var i drift etter at de var kjøpt godt brukt i
7738 2004. Noe var rundt
15 år gammelt, men var fortsatt i bruk. Noen
7739 klaget på at det nå gikk veldig tregt på en del pedagogiske nettsider
7740 med flash o.l. Det er fullt forståelig.
</p
>
7742 <p
>Jeg fikk nylig et spørsmål fra ungdomsskolens rektor om jeg kunne
7743 legge inn
<a href=
"http://freemind.sourceforge.net/
">FreeMind
</a
>, et
7744 tankekartprogram , på skolens elev-Windowsmaskiner. Lærerne hadde
7745 vært på kurs og ville ta dette i bruk. Skolen har ca halvparten av
7746 elevmaskinene på bærbare Windowsmaskiner. Da kunne jeg fortelle at
7747 dette programmet allerede lå inne på den nye Skolelinuxløsningen
7748 som nettopp var satt i drift, klart til bruk.
</p
>
7750 <p
>Vi har de bærbare maskinene på ungdomsskolen i domene med
7751 Skolelinux. Dette fungerer også meget bra nå. Elevene får opp en
7752 midlertidig windowsprofil når de logger på. Denne profilen slettes
7753 etter at de logger av, noe som medfører rene profiler hver gang de
7754 starter opp en maskin. De må lagre i sin Skolelinprofil, noe som
7755 medfører at de får tak i sine filer uavhengig av om de starter en
7756 Windowsmaskin eller en Skolelinuxklient. Det er mye mindre trafikk i
7757 det trådløse nettet etter at ikke hele profiler blir lastet opp til de
7758 enkelte Windowsmaskinene og tilbake når man avslutter. Jeg vet ikke om
7759 dette er standardoppsett i Skolelinux, men slik er vårt oppsett
7762 <p
>Vi har i flere år satt opp vår løsning slik at skriverkøer slettes
7763 og skrivere startes hver natt. Hyggelig å høre at dette nå skal bli
7764 en standard i Skolelinuxløsningen. Dette har vært en god hjelp for
7767 <p
>Elevene er lite opptatt av om de jobber på en Skolelinux eller en
7768 Windowsmaskin bare de har de programmene de trenger og at det virker
7769 når det skal brukes. Vi kjører mest mulig de samme programmene på
7770 Windows som i Skolelinux, som f.eks Audacity og LibreOffice.
</p
>
7772 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7774 <p
>Lærere bruker hos oss Windows. Dette fordi de da selv har mer
7775 kontroll over sin maskin, kan bruke den overalt, og kan legge inn
7776 programmer selv når de trenger noe i forhold til kurs o.l de er
7777 på. Jeg tror lærernes selvstendighet her gjør dem tryggere på IKT-bruk
7778 generelt. Det at de av og til får opp advarsler og lignende gjør også
7779 at de må tenke igjennom og spørre om ting rundt datasikkerhet.
</p
>
7781 <p
>Det er en del programmer vi bruker som ikke finnes for Linux. Mest
7782 brukt er nok Photostory3 som brukes i mange sammenhenger, særlig på
7783 ungdomsskolen, bl.a. til å lage herbarier (plantesamling) . Dette
7784 finnes gratis for Windows, men er ikke fri programvare. Vi er opptatt
7785 av at programmer elevene bruker på skolen også kan brukes gratis
7786 hjemme. Det er også en del programmer som brukes til spesielle elever
7787 som bare går i Windows. Det er viktig med fokus på funksjoner og ikke
7788 på hvilket OS man bruker.
</p
>
7790 <p
>For oss er det kombinasjonen mellom Skolelinux og Windows som gir
7791 oss en god og hel løsning. Skolelinux er best der de er gode.
</p
>
7793 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
7795 <p
>Selv er det LibreOffice jeg bruker til daglig. Jeg bruker selv en
7796 Windowsmaskin. Jeg har benyttet en del fri programvare i forbindelse
7797 med sjekking av trafikk i nettverk, slik som Wireshark, men dette er
7798 jo ikke aktuelt for skolene. Jeg er generelt glad i programmer som
7799 fungerer på både Linux og Windows og gjerne MAC.
</p
>
7801 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
7802 skoler til å ta i bruk fri programvare?
</strong
></p
>
7804 <p
>Det er viktig at det benyttes programmer som elevene også kan ta i
7805 bruk hjemme. Det skal da være enkelt, lovlig og gratis for
7806 elevene. Da er jeg ikke lenger veldig opptatt av om det kalles
"fri
7807 programvare

"gratis
" og
"funksjonelt

7808 begreper enn
"fri

>During christmas, I have been working getting the next version of
7867 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> ready
7868 for release. The initial problem I looked at was particularly
7869 interesting.
</p
>
7871 <P
>The installer would hang at the end when it was doing it
7872 post-installation configuration, and whatevery I did to try to find
7873 the cause and fix it always worked while I tested it, but never when I
7874 integrated it into the installer and ran the installation from
7875 scratch. I would try to restart processes, close file descriptors,
7876 remove or create files, and the installer would always unblock and
7877 wrap up its tasks.
</p
>
7879 <p
>Eventually the cause was found. The kernel was simply running out
7880 of entropy, causing the Kerberos setup to hang waiting for more.
7881 Pressing keys was adding entropy to the kernel, and thus all my tries
7882 to fix the problem worked not because what I was typing to fix it, but
7883 because I was typing.
</P
>
7885 <p
>The fix I implemented was to add a background process looking at
7886 the level of entropy in the kernel (by checking
7887 /proc/sys/kernel/random/entropy_avail), and if it was too small, the
7888 installer will flush the kernel file buffers and do
'find /
' to
7889 generate some disk IO. Disk IO generate entropy in the kernel, and is
7890 one of the few things that can be initated from within the system to
7891 generate entropy.

>Etter en lang pause er det klart for neste mann ut i min serie med
7908 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a

7910 Denne gangen har jeg besøk av et avtroppende styremedlem i
7911 <a href=
"http://www.friprogramvareiskolen.no/
">FRISK
</a
>, og en mann
7912 som har vært aktiv i Linux-miljøet i Bergen siden
90-tallet.
</p

7914 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
7916 <p
>Jeg heter Peter Hansteen, og jobber til daglig som seniorkonsulent
7917 i EDB ErgoGroup i Bergen. I praksis betyr det systemadministrasjon på
7918 Unix (primært Solaris, men en viss komponent av Linux). Men Solaris
7919 er for meg et relativt nytt bekjentskap, hovedplattformen min har
7920 generelt vært OpenBSD og til dels FreeBSD.
</p

7922 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
7924 <p
>Jeg husker ikke helt alle detaljene mer ;) - men jeg tror det var
7925 gjennom news-gruppen no.it.os.unix.linux.diverse, efn-listen og
7926 etterhvert også BLUG-miljøet her i Bergen. Vi hadde et par
7927 Skolelinux-sentrerte BLUG-møter for noen år siden, og det har vært et
7928 par Skolelinux-utviklersamlinger her.
</p
>
7930 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7932 <p
>Jeg bruker dessverre ikke Skolelinux daglig. Men slik jeg kjenner
7933 prosjektet har det vært i stand til å ta opp i seg det beste av fri
7934 programvare i mange kategorier, så fra et sysadmin-perspektiv ser det
7935 ut som en svært behagelig sak. For brukerne er det vel både en fordel
7936 og en ulempe at det ikke er Windows. Men vi håper at fordelene med et
7937 fritt system etterhvert vil bli åpenbare for både elever, lærekrefter
7938 og foreldre.
</p
>
7940 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7942 <p
>Vel, ulempen er vel først og fremst at andre aktører med mer
7943 kapitalmuskel har klart å etablere seg som det både lærere og foreldre
7944 føler seg trygge på, selv om det etter mitt hode ikke er noen grunn
7945 til å være spesielt trygg på de kommersielle alternativene.
</p
>
7947 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
7949 <p
>Når jeg får bestemme helt selv, bruker jeg kun fri programvare. Da
7950 helst med vekt på ting som kjører greit på OpenBSD. Hjemme er det
7951 OpenBSD, Ubuntu eller FreeBSD vi bruker. På skrivebordet er det en
7952 avveining mellom Gnome, KDE eller hva-det-nå-heter som er
7953 standardvalget i Ubuntu, ellers er det de kjente tingene som
7954 LibreOffice, Emacs, mplayer. På server er det selvfølgelig Apache,
7955 for overvåking både OpenNMS og Nagios (det bare ble sånn, og
7956 forskjellige siter). Jeg skriver til tider om slikt jeg holder på med
7958 <a href=
"http://bsdly.blogspot.com
">http://bsdly.blogspot.com
</a
>.
</p
>
7960 <p
>Men vi må nevne at selv vi har en Microsoft-ting som vi slår på når
7961 vi av en eller annen grunn må. Det betyr igjen vanligvis når en
7962 mobiltelefon eller en annen lukket elektronisk dings krever kontakt
7963 via en slik for å få oppdateringene sine.
</p
>
7965 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
7966 skoler til å ta i bruk fri programvare?
</strong
></p
>
7968 <p
>Hadde vi hatt det rette svaret på det spørsmålet, så hadde vi
7969 gjerne hatt Skolelinux som førstevalg på alle skoler ;)
</p
>
7971 <p
>Men jeg tror vi må legge vekt på flere forskjellige ting. En helt
7972 sentral sak er å fokusere på fri programvare og åpne standarder som de
7973 demokratiske verdiene de faktisk er. Det har kanskje kommet litt for
7974 mye i bakgrunnen i forhold til strevet etter å lage det mest mulig
7975 'brukervennlige
' systemet. Det er en tung vei å gå, så det er
7976 forståelig at freenix-aktivister heller velger å skrive kode og annet
7977 som er mer lystbetont. Mer praktisk tror jeg vi må gjøre i alle fall
7978 to ting: For det første sørge for å fortsette med å levere det best
7979 mulige frie produktet, slik at det er lett å både komme i gang og
7980 holde systemene i daglig drift, og for det andre
2) spore opp mulige
7981 aktivister der de finnes, via lokale brukergrupper, sosiale medier
7982 eller annet og sørge for at de fortsetter å være aktive. Mer og
7983 mindre uformelle treff kan være nyttig i tillegg til de mer
7984 organiserte møtene med foredrag, konferanser og utviklersamlinger.

8001 <p
>Mitt navn er Frode Jemtland, og jeg jobber i Hedmark IKT, som er et
8002 driftsselskap for Grue, Hamar, Kongsvinger, Løten, Nord-Odal og Stange
8003 kommuner. Her er jeg leder for avdelingen Løsninger og Arkitektur. Vi

8007 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
8009 <p
>Jobbet i IBM fra
2000, og da spesielt med Linux. Dette var da et av
8010 de mest tydelige linux prosjektene i Norge, og her ønsket jeg å
8011 bidra. Var aktivt med i prosjektet i
4-
5 år.
</p
>
8013 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
8015 <p
>Fordelene slik jeg ser det er den sentraliserte driftmodellen, og
8016 alle de vel gjennomtenkte løsningene som er inkludert i denne
8017 løsningen. Samtidig er det basert på en stabil, og godt kjent
8018 plattform. Dette vil si at man har en løsning som skal være mye
8019 tilgjengelig, og hvor det er relativt enkelt å få tak i personer som
8020 kan mye om den grunnleggende plattformen.
</p
>
8022 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
8024 <p
>De største utfordringene med en løsningen er at den er intensiv på f.eks
8025 nettverk. I seg selv ikke et problem for en enkelt skole, men skal løsningen
8026 kjøres i større skala, med sentraliserte servere, så gir dette noen
8027 utfordringer.
</p
>
8029 <p
>Utifra hva jeg har sett på større installasjoner så er det ikke så
8030 enkelt å skjønne, hva som bør gjøres for at den skal skaleres opp, og
8031 da ta godt vare på alle sider av dette, ikke bare mer server å fordele
8032 last/trykk, men hvordan også beholde robustheten og fleksibiliteten i
8033 løsningen.
</p
>
8035 <p
>En annen utfordring er at stadig flere produkter som skal brukes i
8036 skoleløsningen ikke er laget til å kunne brukes i en
8037 skolelinuxløsning. Det blir derfor fort mye skreddersøm i de
8038 forskjellige installasjonene, for å få diverse pedagogiske programmer,
8039 webløsninger, smartboards, m.m. til å fungere. Man er også en for
8040 liten kundebase til at leverandørene ønsker å gjøre noe med
8041 utfordringen. Problemet overlates til oss.
</p
>
8043 <p
>Det er også en kontinuerlig utfordring rundt problemet med å holde
8044 programvare på stabile versjoner, kontra å få ny funksjonalitet. Dette
8045 er jo en konflikt mellom oss som ønsker å drifte en stabil, og
8046 kostnadseffektiv løsning, mot sluttbrukerne som ønsker seg funksjoner
8047 det er vant med fra andre løsninger, eller som de må ha for at et
8048 eller annet nytt produkt skal fungere i løsningen. Dette er en
8049 utfordring også for andre plattformer.
</p
>
8051 <p
>En siste utfordring som ikke har noe med løsningen å gjøre, men med
8052 det omkringliggende miljøet denne skal kjøre i, er at de enhetene som
8053 skal drifte dataløsninger for kommuner og fylkeskommuner begynner å
8054 profesjonaliseres, og er da avhengig av å ha standard løsninger for å
8055 drifte store brukermasser. MS er selvsagt klar over dette, og har jo
8056 nå flere områder de begynner å bli veldig dominerende på. Den største,
8057 og mest problematiske er katalogtjenesten. Man får snart ikke tak i
8058 større løsninger som ikke krever en AD. Når man da har store enheter
8059 som drifter både kommunalt ansatte og skoler, så vil det være et
8060 stordriftargument å standardisere på en katalog tjeneste, og da har
8061 man ikke noe valg. Her er alle slike driftsenheter for små til å få
8062 gjort om på dette. Her burde konkurransemyndighetene kommet på
8063 banen. Men konkurransetilsynet i USA griper sjeldent (og ikke før det
8064 har gått veldig lang tid) inn i monopolsituasjoner så lenge
8065 monopolisten er et amerikansk firma, så da har vel ikke andre
8066 myndigheter så mye de skulle ha sagt....

><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
8070 <p
>Privat kjører jeg Debian på alle mine datamaskiner. Det gjør jeg
8071 også på min jobbmaskin. Vi har også
15-
20 linux servere av typene
8072 SuSE, Debian, Redhat, CentOS m.m. Jeg bruker derfor mye fri
8073 programvare. Av enkelt programmer kan sikkert masse nevnes. Hvis vi
8074 skal begrense oss til daglig, så må jeg si: OpenOffice, Firefox,
8075 Kontact, Kopete, Amarok,
8076 <a href=
"http://gramps-project.org/
">Gramps
</a
>, Kate, ssh, bash,
8077 rsync, backuppc m.m.
</p
>
8079 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
8080 skoler til å ta i bruk fri programvare?
</strong
></p
>
8082 <p
>Det er et godt spørsmål, som jeg har lurt på selv.
</p
>
8084 <p
>Argumentene som ofte har vært brukt om at ting koster mindre holder
8085 ikke mål når man ser på hva som faktisk koster penger. Det er de
8086 ansatte som er en kostnadsdriver. Det vil si at hvis man har et system
8087 som den ansatte kan, så vil en kostnad på dette systemet kunne
8088 forsvares ganske mye ved at den ansatte gjør dette raskere og
8089 effektivt. Også uten å måtte eventuelt leie inn folk.
</p
>
8091 <p
>Jeg syns det er viktigere å fokusere på prinsippet med å velge fri
8092 programvare, men det er også et felt hvor man fort møter lite
8093 forståelse blant de ansatte i skolen.
</p
>
8095 <p
>Her må nok strategien fortsette å være at de sentrale myndighetene
8096 må sende tydelige signaler for hva de ønsker at offentlige enheter
8097 skal gjøre. Det var mye positivt på gang ang. dette for et par år
8098 siden. Både med eNorge og eKommune planene, men dette syns jeg har
8099 stoppet opp. En del av dette kan jo kanskje være usikkerheten som
8100 etter hvert har blitt, når man har sett kompleksiteten i de
8101 prosjektene som har blitt igangsatt. Det har også blitt noe usikkerhet
8102 i markedet ref. Sun, Oracle, Novell, Microsoft m.m. Samtidig har jo
8103 også de proprietære programleverandørene sørget for å endre sine
8104 lisenser slik at man uansett ikke slipper unna kostnaden til deres
8105 produkter, selv om man skulle velge alternativer. Da er det økonomiske
8106 argumentet, som jeg nevnte tidligere, spilt ganske godt ut over
8107 sidelinjen.

8130 <p
>Hmm, det er lenge siden, så det er nesten så jeg ikke husker. Jeg
8131 hadde vel hørt om prosjektet i media før en gjeng i Trondheim startet
8132 opp SPIST, Skolelinux-prosjektet i Sør-Trøndelag, hvor vi hjalp noen
8133 skoler i nærområdet med å installere Skolelinux og finne brukt
8134 IT-utstyr til disse. Det var moro å gjøre noe praktisk for å spre
8135 Skolelinux, og å se hvor fort gjort det var å sette opp utrangerte
8136 klientmaskiner og få disse opp som tynnklienter på helt nye datasaler
8137 på skolene, kun med kostnaden til servere.
</p
>
8139 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?

8141 <p
>Det er et system spesielt skreddersydd for drift av et stort antall
8142 klienter mot servere, og da spesielt i henhold til skolers behov. Det
8143 er enkelt og billig å installere og drifte, og det trenger ikke ny
8144 maskinvare for god ytelse.

>Hardwarestøtten kunne vært bedre og i enda større grad
8149 installerbart rett ut av boksen. Distribusjonen har til tider hatt
8150 litt gammel programvare pga. at den følger Debian sine utgivelser.
8151 Kanskje man skulle vurdert en versjon basert på Ubuntu eller andre
8152 distribusjoner i tillegg?

8168 fleksibilitet, åpenhet og ikke låsing til en leverandør framfor sparte
8169 lisenskostnader, samt programvarens kvalitet og fortrinn, og at den
8170 fritt kan brukes på et ubegrenset antall PC-er, også hjemme hos
8171 elevene. En bør også forbedre den fri programvaren ved testing,
8172 bugrapportering og kodebidrag om man kan, og ikke anbefale programvare
8173 uten at man har forsikret seg at den har tilstrekkelig kvalitet,
8174 ellers kan man lett oppnå det motsatte. Tror en bør selge inn
8175 konseptet til fylkes-/statsnivå, kanskje med bidrag til
8176 utviklingsarbeid fra disse som alle landets skoler kan få glede

>Mine bloggposter om Linux i skolene i Norge førte til at inspektør
8187 og ildsjel på Harestad skole tok kontakt og fortalte at de bruker
8188 Linux på sin skole, og lurte på om de kunne bidra til å gjøre
8189 fordelene kjent. Riktig nok bruker de ikke
8190 <a href=

">Skolelinux
</a
> på denne skolen,
8191 men jeg synes dette er en god anledning til å gjøre flere fasetter
8192 rundt Linux-økosystemet kjent, og tok et lite intervju.

8196 <p
>Mitt navn er Odin Hetland Nøsen og er en
70-modell. Jeg er bosatt i
8197 Stavanger og jobber nå på
9. året som undervisninginspektør på
8198 Harestad skole i Randaberg kommune (nabokommune til Stavanger).
</p

8200 <p

8202 <p
>I
2002 begynte daværende IKT-ansvarlige og jeg et arbeid på skolen
8203 med å gå over fra Win98 til... noe annet. Vi testet en rekke
8204 forskjellige løsninger, deriblant Skolelinux, men endte opp med
8205 RedHat. Skolelinux var den gang ikke modent for det vi ville ha. Jeg
8206 har siden fulgt jevnlig med på hva skolelinux holder på med, men har
8207 hele tiden vært bedre fornøyd med vår egen
"standardiserte
" løsning på
8208 RedHat/CentOS og Fedora. Vi snuser for tiden på Ubuntu som løsning på
8209 klientsiden.
</p
>
8211 <p
>I dag har vi på skolen vår en større linux-løsning med
400 klienter
8212 som kjører en blanding av LTSP (tynnklient) og DRBL (tykk klient uten
8213 harddisk) med en masse tjenere på serverrommet. Vi drifter hele
8214 sulamitten selv med webtjener, eposttjener, webmail, filtjenere,
8215 virtuelle tjenere osv. Og IT-ansvarlig har en
80% stilling som
8216 IT-ansvarlig - og så er han KoH-lærer i de resterende
20% :-)

8219 <a href=

</a

</p
>
8221 <p
>For å ta brodden av frykten for at ildsjeler gjør skolen sårbar om
8222 ildsjelene falle fra, har jeg forsikret kommunen og skolesjefen i
8223 Randaberg om at det finnes godt kommersielle tjenester vi kan benytte
8224 oss av - om det skulle bli nødvendig. Vi er tre stykker i kommunen som
8225 nå har
<strong
>god
</strong
> linux-kompetanse ift. å drifte et større
8226 system. IT-avdelingen i kommunen vil ikke ta på oss med ildtang -
8227 selv om vi nok har større IT-kompetanse mot linux enn det de selv har
8228 mot windows (de kjøper en
<strong
>masse
</strong
> konsulenttjenester
8229 fra ErgoGroup).
</p
>
8231 <p
>I kvantitet er Harestad og Grødem skole tilsammen et større
8232 IT-system enn resten av Randaberg kommune + Kvitsøy og Rennesøy, som
8233 kommunen også har driftsansvar for. Vi har som sagt rundt
800
8234 maskiner, mens kommunen med sitt driftsansvar har ansvar for rundt
500
8235 maskiner. Det er selvfølgelig litt forskjell i hvor kritiske
8236 tjenestene våre er, men det gir allikevel et litt rart bilde når
8237 IT-avdelingen overhode ikke er interessert i å snakke med oss om
8238 hvordan vi gjør ting :-)
</p
>
8240 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
8242 <p
>Fra linux-perspektivet (ikke bare Skolelinux) er det en fordel av
8243 systemet er basert på fri programvare - og dermed fritt i ordets mange
8244 betydninger. Det er alt vi trenger: stabilt, relativt enkelt å drifte
8245 (tross alt - et større windowssystem er ikke enkelt å holde live det
8246 heller), rimelig i innkjøp og drift, og sist, men ikke minst, det er
8247 moderne for sluttbruker! Linux, i sine mange varianter,
8248 <strong
>ser
</strong
> nytt ut, fordi det hele tiden blir
8249 oppdatert. Derfor lever systemet opp til hvordan elever forventer at
8250 et moderne GUI skal være (i motsetning til WinXP :-).
</p
>
8252 <p
>Vi var veldig pragmatiske da vi begynte med linux i skolen. Det var
8253 billig, det fungerte og kunne bruke alle de gamle windows-maskinene
8254 som
"nye
" tynne klienter. I dag er vi mer bevisste fri
8255 programvare-tilhengere. Vi har oppdaget hva det er - og vi liker
8258 <p
>En av de
<strong
>store
</strong
> fordelene med fri programvare er at
8259 vi kan installere tjenester vi ønsker å tilby brukerne våre - uten å
8260 måtte tenke på om vi har råd til lisensene (fordi det er ingen). Alt
8261 vi setter i produksjon er ut i fra brukernes behov og vår kapasitet
8262 til å drifte dem. Vi skreddersyr tjenestene etter behovet og dermed
8263 trenger vi ikke ende opp med å kjøpe en pakke der vi egentlig bare var
8264 interessert i en liten del av den.
</p
>
8266 <p
>Bruk av linux frigjør ikke økonomiske midler, fordi midlene til IKT
8267 i skole er for få i utgangspunktet - men vi får så
8268 <strong
>mye
</strong
> mer igjen for dem når vi bruker en linux-løsning
8269 fremfor en windows-løsning. I praksis ser vi at vi måtte ut med det
8270 dobbelte på budsjettet vårt om vi skulle hatt en tilsvarende
8271 windows-løsning, som det vi i dag drifter med linux.
</p
>
8273 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
8275 <p
>Ikke all pedagogisk programvare er tilgjengelig. Det er en del
8276 programvare i skolen som er laget med utviklerverktøy som bare virker
8277 i windows, f.eks. Drillpro, LingDys/LingWrite. Det er også
8278 "programmer
" som bare virker om du har tilgang til Microsoft Office,
8279 f.eks. AskiRaski.
</p
>
8281 <p
>Vi sliter også litt med at video-codecer ikke alltid er like lett å
8282 få opp å gå på klientene. Det er alltid en eller annen videosnutt fra
8283 nrk.no som ikke er så samarbeidsvillig, uansett mediaplayer.
</p
>
8285 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
8287 <p
>Alt :-) På skolen bruker vi det som finnes og som er nyttig. Det vi
8288 bruker mest er Firefox (jobber med Chrome, fordi det er
8289 <strong
>mye
</strong
> raskere med Flash enn Firefox), OpenOffice (skal
8290 over til LibreOffice), GIMP osv. Standardpakken av
8291 sluttbrukerprogrammer.
</p
>
8293 <p
>På tjenernivå bruker vi OpenWebMail (skal over til Zimbra), Exim
8296 <p
>Personlig bruker jeg de fleste programmer over flere plattformer,
8297 men jeg har lagt meg til en vane å prioritere bruken av fri
8298 programvare også i Windows
7 og OSX.
</p
>
8300 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
8301 skoler til å ta i bruk fri programvare?
</strong
></p
>
8303 <p
>Jeg er langt i fra sikker. For det første handler det mye om at
8304 IKT-avdelingen i kommunen ofte er de som styrer hva som er IKT på
8305 skolene - og de liker å bruke avtalene med Microsoft, som de garantert
8306 har fra før. Dessuten - Select
6-avtalen til skolene gjør Microsoft
8307 skvettbillig.
</p
>
8309 <p
>Vi la vekt på effektiv drift av systemet - og at vi kunne øke
8310 antall maskiner uten å måtte øke budsjett for utstyr eller personell
8311 særlig mye, enn om vi hadde gått for en Microsoft-løsning. I praksis
8312 ser vi at en ren linux-installasjon driftes til halve prisen av en
8313 Microsoft-løsning.
</p
>
8315 <p
>Vi har i praksis også sett at det lærerne (og elevene) liker er at
8316 vi tilbyr
<strong
>veldig
</strong
> mange tjenester som ikke er så
8317 vanlige i en Microsoft-løsning. Det er ikke så vanlig at
8318 <strong
>elevene
</strong
> også har epost, hjemmekontor osv. Det har vi
8319 også brukt som et vellykket argument mot Microsoft.
</p
>
8321 <p
>Den beste måten er selvfølgelig at noen bare bestemmer
8322 det. Problemet er å få dem som har makt til å bestemme det til faktisk
8323 å gjøre det ;-)

8339 <p
>Jeg heter Astri Sletteng. Jeg er lærer og IKT veileder ved Håkvik
8340 skole i Narvik kommune. Min bakgrunn når det gjelder IKT: Av formell
8341 utdannelse har jeg lærerutdanning, Master i skoleledelse og IKT for
8342 lærere. Har jobba som IKT veileder siden
2002.
</p
>
8344 <p
>Det viktigste for meg som IKT veileder er å få fundamentert den
8345 5. basisferdigheten, digital kompetanse ved skolen min på en god måte
8346 slik at hele skolesamfunnet tar i bruk IKT i alle fag. Dette arbeidet
8347 gjøres i nært samarbeid med skolens ledelse.
</p
>
8349 <p
>Min viktigste jobb som IKT veileder er å være motivator og pådriver
8350 i IKT arbeidet ved skolen.
</p
>
8352 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p

8354 <p
>Jobber i en kommune hvor vi satser på Fri programvare. I
2004 ble
8355 det gjort et politisk vedtak om at vi skulle innføre Skolelinux ved
8356 alle skolene i kommunen. Jeg har dermed en god del erfaring med
8357 Skolelinux, samt annen fri programvare som Open Office, Joomla, Moodle
8360 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
8362 <p
>Siden vi jobber med åpen kildekode kan vi få programmene og
8363 produktene tilpasset vår bruk. Det er jo heller ikke en ulempe at
8364 skolen kommer bedre ut økonomisk, men først og fremst er det viktig
8365 for oss at vi har digitale systemer som gjør at vi kan følge
8366 læreplanen i alle fag. Det syns jeg at vi kan gjøre gjennom
8367 Skolelinux.
</p
>
8369 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
8371 <p
>Skolen er avhengige av å ha folk på IT avdelinga i kommunen som kan
8372 drive support, og være tilgjengelige når vi trenger hjelp. Det er en
8373 ulempe at ikke alle på denne avdelingen nødvendigvis er god på
8376 <p
>Vi har også noen utfordringer når det kommer til spesielle
8377 programmer som enkelte elever er avhengige av ? og som ikke er
8378 plattform uavhengige. Her har vi i Friprog-verden, men også
8379 departement en jobb å gjøre.
</p

8381 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong

8383 <p
>Skolen vår bruker Skolelinux, Open Office, Iceweazel (Mozilla),
8384 VLC, Tux paint, Scribus, FreeMind, GIMP, digiKam, Ksnapshot, GeoGebra,
8385 Moodle (innført på alle klassetrinn + som et administrativt verktøy)
8386 og Joomla som hjemmeside.
<p

8388 <p
>Det er de jeg kommer på i farten. I tillegg har vi Smartboard
8389 installert på server, men det regnes vel ikke som fri programvare?

>Hvilken strategi tror du er den rette å bruke for å få
8392 skoler til å ta i bruk fri programvare?
</strong

8394 <p
>Først og fremst trenger skolen oppetider på sine datasystemer. Syns
8395 også at det at vi kan få tilpasset plattform og systemer til vår bruk
8396 er en god strategi å bruke.

>Rubén Romero y Cordero,
81-modell, deltidspappa (
50%) for en jente
8413 på
6 år. Jobber i Oslo som Global Sales Executive hos Varnish Software
8414 og til daglig har jeg kontakt med kunder fra hele verden. Min
8415 forkjærlighet for fri programvare har gjort at jeg har nå flere års
8416 erfaring med salg av slike løsninger (bl.a. fra Redpill Linpro og
8417 Freecode) og mye innsikt og kunnskap om det globale IT-markedet.
8418 Ellers er jeg involvert i flere prosjekter bl.a. er jeg Ubuntu
8419 Community medlem, kontaktpersonen for Ubuntu Norge og driveren av
8420 SpreadUbuntu marketing prosjektet og nå fersk styremedlem i FRISK. Jeg
8421 har brukt GNU/Linux siden
1997.

><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
8425 <p
>Som Debian bruker siden slutten av
90-tallet var det uunngåelig å
8426 ikke komme bort i Skolelinux. Dette var vel i slutten av
2001 når jeg
8427 var student ved UiO. Flere år senere fikk jeg lastet og testet Venus
8428 (Skolelinux
1.0) på release dagen.
</p
>
8430 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
8432 <p
>Fri programvare bygges sten for sten i det åpne, slik at koden og
8433 prosessen den lages på kan gjennomskues av andre enn de som har laget
8434 det. Det er et vitenskapelig og gjennomsiktig måte å lage programvare
8437 <p
>Skoler i vårt samfunn skal være steder hvor vitenskapelig kunnskap
8438 deles til alle. I dag har vi ikke et vitenskapelig tilnærming til
8439 hvordan programvaren som brukes på skolen lages. Skolelinux bringer
8440 inn at slik tilnærming i skoleverkets klasserom, siden
8441 operativsystemet er en åpent platform som gir skolene muligheten til å
8442 dra nytte av programvare som er laget av tusenvis av mennesker verden
8443 rundt og som gir elevene så vel som lærerne muligheten til å bruke,
8444 dele, forandre og forbedre OSet sitt uten begrensninger. I den
8445 forbindelsen representerer Skolelinux også konkrete resultater utfra
8446 samhandling på tvers av grenser.
</p
>
8448 <p
>Når det gjelder de tekniske fordelene av Skolelinux er jeg sikker
8449 på at andre enn meg har allerede beskrevet disse bedre enn det jeg
8450 kan. Men jeg kan likevel tilføye noe: Skolelinux som sådan er en
8451 community-drevet operativsystemplatform. Som i ethvert
8452 community-prosjekt har alle Skolelinux brukere muligheten til å
8453 påvirke retning av prosjektet og resultatet som gjenspeiles i
8454 programvaren. Dette kommer sjeldent frem og jeg mener at det er noe
8455 som burde fokuseres mer på.
</p
>
8457 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p

8459 <p
>De største ulempene er:
</p
>
8462 <li
>Mangel på kompetanse
</li
>
8463 <li
>Mangel av administrative verktøy som kunne hjelpe lokale IT
8464 avdelinger å bruke Skolelinux til mer enn bare en tjener for
8465 terminalklienter. Et eksempel: Zentyal sin web-dashboard.
</li
>
8468 <p
>Bedre og mer intuitive administrative verktøy kunne løst deler av
8469 problemet, men det er unektelig at ved bruk av Skolelinux må
8470 IT-personalet vite hva de gjør for å få ting gjort riktig, eller i det
8471 hele tatt. Med andre platformer er kompetansen enklere tilgjengelig og
8472 løsningene kan fungere på en tilfredstillende, om ikke riktig

8477 <p
>Har brukt GNU/Linux utelukkende sommitt skrivebord OS siden
2000. I
8478 dag bruker jeg Ubuntu og gjør det meste med friprogramvare verktøyene
8479 som er tilgjengelige der. Med over
20.000 programmer å velge mellom er

8486 programvare. De fleste utfordringene skolene har på IKT-siden kan
8487 løses ved hjelp av friprogramvareverktøy i dag. Det som trenges er
8488 opplysning, kunnskap og kompetanse.

8515 <p
>Skolelinux har jeg møtt ved flere anledninger opp gjennom åra, både gjennom
8516 entusiastiske skolelinuxbrukere og skeptiske
"forståsegpåere
" :-)
</p
>
8518 <p
>Jeg husker en leverandør av et stort OS for noen år siden mente at
8519 Skolelinux var kun for hackere og nerder og at ingen seriøse skoler
8520 kunne ta dette i bruk. Heldigvis er kunnskapen større nå og
8521 skikkelige
"IT-folk
" søker alltid å utvide sin kunnskap.
8523 <p
><strong

</strong

8525 <p
>Ja det er mange fordeler. Uavhengighet, stabilitet, åpenhet, standarder

8527 elevene skal jobbe.
</p

8529 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong

8531 <p
>Det største hinderet er det vi opplever på andre områder rundt
8532 fri programvare, nemlig kunnskap. For mange er det trygt å velge det vi
8533 alltid har valgt. Fordi leverandørene rundt oss sitter på den kunnskapen og
8534 de vi støtter oss på har den samme. Hvis vi klarer å riste løs litt og
8535 glemme gamle kriger mellom operativsystemer og leverandører, men sette ned
8536 hva som er viktig og velge ut fra det, så hadde man kanskje kommet ut med
8537 litt andre resultat. Jeg tror IT-folk er konservative og velger tradisjonelt
8538 og det er synd.

8540 <p

8542 <p
>Jeg bruker Ubuntu, Android, Jolicloud, Open Office, Zimbra, Picasa
8543 og Firefox samt en bråte med tjenester som er webbasert. Det eneste
8544 som er betalingslisens for er OSX. Ser at jeg jobber mer og mer i
8545 skyen og setter pris på alt jeg slipper egen klient til. Derfor er
8546 jeg veldig sjarmert av små kjappe operativsystemer som krever minimalt
8547 av maskinvaren.

><strong
>Hvilken strategi tror du er den rette å bruke for å få
8550 skoler til å ta i bruk fri programvare?

8552 <p
>Tror en blanding av krav og informasjon er veien å gå. Krav om
8553 sikkerhet, oppetid og åpne standarder. Informasjon om muligheter og
8554 alternativer. Her har leverandører, IT-avdelinger og pedagoger en vei
8555 å gå sammen. Det er til slutt LÆRING det dreier seg om, og da må man
8556 få mest mulig læring for pengene man har.

8573 <p
>Sturle Sunde, ansvarleg for skulenettet i Flora kommune. Eg driv,
8574 vidareutviklar og er andrelinje brukarstøtte for datanettet ved
8575 skulane i Flora kommune.
10 skular og meir enn
700 maskiner med
8576 Linux, medrekna tynnklientar. Tidlegare jobba eg i mange år med
8577 unix-drift ved Universitetets senter for informasjonsteknologi ved
8578 Universitetet i Oslo.
</p

8580 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
8582 <p
>Det er vanskeleg å svare konkret på. Eg har drive med Unix og Linux i
8583 alle år, og Skulelinux er eit godt kjent prosjekt i miljøet. Det var
8584 først i
2008, då eg tok til i min noverande jobb, at eg fekk bruk for
8585 Skulelinux for alvor.
</p
>
8587 <p
>Jobben min skulle vere drift av eit nytt skulenett i Flora kommune,
8588 levert av eit firma eg ikkje vil reklamere for. Systemet skulle vere
8589 ferdig levert i september året før. Dette viste seg å ta mykje lenger
8590 tid, og i haustferien
2008 hadde dei endå ikkje klart å få opp ei
8591 fungerande løysing. Situasjonen var prekær for den største skulen i
8592 kommunen med meir enn
500 elevar på ungdomssteget. Skulen hadde brukt
8593 Skulelinux før, og var tilfredse med det. No hadde dei vore utan
8594 fungerande datasystem i nesten eit år. Difor fekk eg opp ein ny tenar
8595 utanfor prosjektet og installerte Skulelinux på den. Etter litt
8596 justering av konfigurasjonen med god hjelp av #skolelinux på IRC, var
8597 den nye tenaren oppe og gjekk med både tynne og halv-tjukke klientar.
8598 Autentisering gjekk mot det nye systemet, slik at elevar og lærarar
8599 framleis har same brukarnamn og passord over alt. Dette berre
8600 fungerte, og vi bestemte oss for å erstatte delar av løysinga vi
8601 skulle få levert med Skulelinux.
</p
>
8603 <p
>Det høyrer med til historia at det nye systemet eg skulle drive frå
8604 januar
2008 endå ikkje er ferdig levert. Dei jobbar med saka, seier
8605 dei, og har von om å fullføre leveransen i løpet av
2011.
</p
>
8607 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
8609 <p
>Det er veldig mange. Eg skal ta nokre få.
</p
>
8611 <p
>Den viktigaste fordelen er at det igrunn berre er ei maskin å passe
8612 på, og det er tenaren. Med andre løysingar har ein gjerne programvare
8613 og anna som skal vedlikehaldast på kvar enkelt maskin. Med Skulelinux
8614 kan alle feil rettast og alle program oppgraderast på alle maskiner
8615 samstundes ved å gjere endringa som må til på tenaren. Eg kan sitje
8616 på kontoret og passe på alle tenarane i kommunen derifrå.
</p
>
8620 <li
>Tynne klientar gjer det mogleg å bruke eldre utstyr lenge, so lenge
8621 tenaren er sterk nok. Ein liten tenar med eit par halv-moderne CPUar
8622 og
2 GiB RAM held lenge for eit typisk klasserom med
30 tynnklientar,
8623 og det er lett å utvide med fleire.
8625 <li
>Halvtjukke klientar gjer det mogleg å utnytte kapasiteten i litt
8626 nyare maskiner betre, og avlaste tenaren. Ingenting vert installert
8627 lokalt på desse heller, og harddisken kan gjerne koblast frå. Gode
8628 halvtjukke klientar kan kjøpast brukt for under
1000-lappen, og det er
8629 heile kostnaden. Ingen lisensar eller anna på toppen, og det er ikkje
8630 krav til kraftigare tenar heller.
8632 <li
>Det er Linux. Vi har ikkje noko kluss med drivarar, dei berre er
8633 der. Heller ikkje med virus, dei finst i realiteten ikkje. Eller med
8634 elevar som klussar med installert programvare, for dei klarar ikkje å
8635 øydeleggje for nokon andre enn seg sjølve.
8639 <p
>Skulelinux er lagt opp til å vere veldig lett å installere rett ut
8640 av boksen på ein heil skule av ein interessert lærar. Det er ofte ei
8641 god løysing for skulen. Å ha nokon til stades som kjenner systemet og
8642 kan forklare enkle ting eller løyse problem der og då, er uvurderleg
8643 viktig for ein stressa lærar fem minutt før det ringer inn.
</p
>
8645 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
8647 <p
>All den ferdige konfigurasjonen gjer det tungvint å tilpasse
8648 Skulelinux til eit system som skal fungere saman med mange andre
8649 installasjonar i eit felles datanett for skulane i ein kommune. Det
8650 heile er prekonfigurert for ein skule, og utviding til mange skular
8651 med eigne tenarar er ikkje berre enkelt.
</p
>
8653 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
8655 <p
>Eg brukar mest alle små hjelpeprogram som føl med operativsystemet,
8656 samt scriptspråket perl. Elles er Firefox/Iceweasel, Gnome-terminal
8657 og ssh i kontinuerleg bruk. Av Linux-distribusjonar brukar eg både
8658 Debian, Ubuntu, SuSE og RedHat dagleg. Eg prøvar å finne det verktyet
8659 som passar best til kvar del av jobben.

>
8661 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
8662 skoler til å ta i bruk fri programvare?
</strong
></p
>
8664 <p
>Det er to målgrupper ein må sikte mot. Det eine er alle skulane som
8665 manglar eller har eit lite tilfredsstillande opplegg i dag, og ikkje
8666 har råd til å kjøpe noko nytt og blankpussa opplegg. Der er det om å
8667 gjere å gjere det enkelt for skulane å finne Skulelinux, og gjere det
8668 enkelt for dei å få hjelp til installasjon på skulen. Gjerne med
8669 lokale kontaktpersonar. Her er det dugnadsinnsats som må til, for
8670 desse skulane har ikkje råd til å betale for dette.
</p
>
8672 <p
>Den andre og kanskje viktigare målgruppa er dei meir eller mindre
8673 profesjonelle kundane. Alle store offentlege innkjøp, inkludert
8674 innkjøp av nytt datasystem for skular, må ut på offentleg anbod.
8675 Offentlege anbod er mykje meir lukka enn dei gjev inntrykk av, og både
8676 regelboka og boka med triks for å sminke tilbodet er tjukk. Det er
8677 vanskeleg å komme inn utan eit solid salsapparat i ryggen. Kanskje
8678 Skulelinux skulle prøve aktivt å få seg eit partnarskap med eit av dei
8679 store som gjerne vil sterkare inn på den offentlege IT-marknaden?
8680 Nokon som kjenner triksa og har krefter til å ta opp kampen mot både
8681 dårlege anbod og Rudolf Blostrupmoen IT AS. Leveranse til skulane i
8682 ein kommune er ein god måte å få ein fot inn døra som leverandør til
8683 ein lukrativ kommunemarknad som kjøper alle tenester. Ta kontakt med
8684 nokon som er passeleg store og ikkje er Microsoft-partnar, og fortell:
8685 «Vi har eit ferdig produkt som du kan selje. Nei vi skal ikkje ha for
8686 det. Du kan gjerne gjere kva du vil med det, berre vi får lov til å
8687 hjelpe deg. Målgruppa er alle kommunar, og det er noko dei vil ha.
8688 Det er eit godt produkt, brukt av mange og godt likt.»

8708 40% lærer og
60% IKT med Windows XP, Win2003 server og et regionalt
8709 IKT-regime som legger premissene og begrensingene for hva vi kan gjøre
8710 på skolen.

8714 <p
>Jeg leste en artikkel om en dugnadsinstallasjon av Skolelinux på en
8715 skole på Jæren et sted. Tanken om dugnad og frihet appellerte til
8716 meg. Da vi skulle bygge ny skole var det en del vi måtte spare på,
8717 fordi vi beveget oss mot en kostnadssprekk. Kabling og investering i
8718 PC-er var en av tingene vi sparte på. Derfor kjøpe vi
72 pc-er for
390
8719 pr stk. En filtjener og en applikasjonsserver.

8721 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p

8723 <p
>Fordelen er at så mye er satt opp fra starten. I tillegg er det
8724 tydelig at pakka er laga for skoleverket. Brukerne har egne
8725 skrivebord, tilgang på mange gode verktøyprogrammer. Vi slipper å
8726 tenke på virus. Brukerne har ikke mulighet til å ødelegge
8727 klientoppsett, men har gode muligheter til å endre eget oppsett. Dette
8728 tror jeg er inspirerende og kjekt for mange brukere. Mappestrukturen
8729 er ferdig og det er
"enkelt
" å designe lokale mappestrukturer via
8730 skeleton. Noen av oss i skoleverket mener skolen skal være en
8731 "mot-kultur
". Da er Skolelinux et av valgene man kan ta. Et annet er å
8732 spise på indisk restaurant i stedet for Mc Donald
's når vi er på bytur
8733 osv.. Ordene deling, frihet, dugnad osv er positive ord i
8734 skoleverket. Det er viktig at elevene blir bevisst dette.

8736 <p

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

8738 <p
>Kompabiliteten er selvsagt et problem, selv om det er mindre nå enn
8739 før. For IKT-personer på skolene som skal drifte dette er det
8740 problematisk med kommandoer i terminalen. I tillegg er det alt for
8741 mange programmer i Skolelinux som ikke blir brukt. Jeg tror
8742 Skolelinux er tjent med å tone ned begrepet pedagogisk programvare.
8743 Slik jeg ser det finnes ikke denne kategorien programmer lengre slik
8744 de gjorde før, som frittsående programmer som installeres på en
8745 datamaskin eller på serveren. Det finnes en del spesialpedagogiske
8746 programmer, som Textpilot, LingDys, LingRight, AskiRaski, Ny i Norge
8747 osv. Men dette er programmer for enkelt-elever eller små grupper av
8748 elever. Det som bør være fokus er at alle undervisningsressurser som
8749 lages for nettet skal være nettleseruavhengig.

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

8753 <p
>OpenOffice bruker jeg til vanlig kontorarbeide. VLC bruker jeg som
8754 videoavspiller og av og til streaming av film. Gimp bruker jeg i
8755 undervisningen til bildemanipulering. Firefox og Chrome er mine
8756 favoritt-nettlesere. Firefox har lenge vært førstevalget mitt, nå
8757 bruker jeg mest Chrome. Opplever den som raskere og smidigere enn
8758 Firefox. Ubuntu bruker jeg som dualboot på jobb-maskinen min i
8759 tillegg til at alle PCer hjemme har en eller annen Ubuntu-distribusjon
8760 installert. Jeg bruker Clonezilla på Ubuntu
10.04 til kloning av
8761 datamaskiner på jobb. Det er selvsagt en haug andre frie programmer
8762 jeg bruker men jeg bruker dem ikke daglig. Jeg kan ramse opp:
8763 recordmydesktop, cinelerra, acidrip, soundjuicer, audacity, NX
8764 (no-machine), Kino, Rythmbox...

>Hvilken strategi tror du er den rette å bruke for å få
8767 skoler til å ta i bruk fri programvare?
</strong
></p
>
8769 <p
>Jeg tror oppsøkende virksomhet er den rette strategien.
8770 Ressurspersoner gjør avtaler med rådmenn, skolesjefer, rektorer. Det
8771 er slik konkurrentene gjør det. Fokuset i slike samtaler bør være
8772 kost-nytte. Dersom personer med økonomisk ansvar ser at de kan få
8773 like godt tilbud til mindre utgifter, tror jeg det er mulighet til å
8774 få innpass. Dersom de også kan få konkrete tilbud på drift i slike
8775 samtaler, vil de kanskje bli litt mer interesserte i hvor mye penger
8776 som faktisk går til IKT i skolene. Det er også viktig at vi ikke
8777 firer for mye på krav til datamaskiner. Det er flott at Skolelinux
8778 går på
"utrangert
" utstyr, men dette bør bare presenteres som et
8779 alternativ. Skolelinux-installasjoner med utrangert utstyr er ikke å
8780 foretrekke dersom man kan unngå det. Det skaper ikke entusiasme hos
8781 brukerne (elever og lærere) når de bruker gamle datamaskiner som går
8782 tregt. Det er kjempefint med skoler som har kommet seg frem til
8783 Skolelinux og fri programvare av seg selv, men de lever på nåde.
8784 Slike valg må fundamenteres hos skoleeier.

8815 <p
>Gjennom en eller annen nettavis i
2001 der var det skrevet om
8816 Skolelinux. Artikkelen ga meg lyst til å prøve ut systemet.
</p

8818 <p
>Det startet i
2002 ved at jeg installerte en av de første utgavene
8819 av Skolelinux på en standard pc på Solneset skole i Tromsø. Denne var
8820 oppe fram til desember
2003 da jeg sluttet på den skolen og begynte i
8821 ny jobb i Narvik kommune.

8823 <p
> I Narvik kommune var det i
2004 kun
2 servere på da totalt
15
8824 skoler. Disse var Windows NT baserte. På disse to skolene var det lite
8825 med maskiner. Jobben med å få Narvik Kommune opp på akseptabelt nivå
8826 virket å være formidabel. Men med hjelp av gode kollegaer og leder
8827 skrev jeg en IKT plan for Narvik kommune som ble vedtatt av politikere
8828 i august
2004. I denne planen ble det bestemt at Narvik kommune skulle
8829 bruke Skolelinux. Her ble det også satt av midler til kabling av god
8830 infrastruktur på alle skoler samt innkjøp av nye datamaskiner. Så i
8831 dag har vi
17 servere hvorav
13 er på Skolelinux, med ca
1500 klienter

8915 men det virker ut som det ikke skjer noe mer på. I tillegg var vi med

8923 en arkitektur med sentral-drift som gir mange driftfordeler. I
8924 tillegg vil det kunne frigjøre kostnader for skolene slik at de kan

8967 <p
>Kommunen min har to omtrent jevnstore tettsteder, og en
8968 ungdomsskole i hvert av tettstedene. Den minste av disse har ca
300
8969 elever og til denne sogner det
3 barneskoler. Den største har ca
350
8970 elever og til denne sogner det
4 barneskoler.
</p
>
8974 <li
>Kommunen har i veldig lang tid forsømt IKT i skolen, og det har
8975 bare blitt gitt smuler i ny og ne. Det er kun den største av
8976 ungdomsskolene som har hatt en skikkelig datapark, og dette takket
8977 være en naturfaglærer som ble lei av å vente på kommunen. Det gjorde
8978 at vi bestemte oss for å ta ting i egne hender, og da vha
8979 skolelinux. En testinstallasjon med
10 gamle PCer ble gjort, og vi så
8980 raskt at dette var veldig lovende. Neste etappe var å gi alle lærere
8981 egen PC på arbeidsplassene sine (
2004), og så sette opp
16 PCer på to
8982 datarom. Vi har kun basert oss på å kjøpe inn brukte maskiner, og
8983 aldri dyrere enn
1000 kr pr klient. For to år siden så hadde vi
8984 klienter i alle klasserom, og totalt hadde vi da rundt
250 stk. Rundt
8985 40 klienter brukes av lærerne og kjører på en egen server. Elvene har
8986 resten, og kjører også en egen server. Servere har vi også kjøpt
8987 brukt,
2 år gamle servere koster
6-
7000 kroner.
</li
>
8989 <li
>Skolen vår er et relativt gammelt bygg, men en meget dyktig
8990 vaktmester har sammen med IKT-ansvarlig/Naturfaglærer lagt kabler til alle
8991 rom. Gradvis har vi byttet ut billige svitsjer med mer solide saker
8992 som er mulig å fjernstyre.
</li
>
8994 <li
>Vi har i all hovedsak greid å få dette til over eget budsjett, men
8995 vi har også passet på å få penger når de andre skolene har fått
8996 bærbare PCer til lærere osv.
</li
>
8998 <li
>Vår IKT-ansvarlig har gjort (og gjør) en fenomenal jobb, og vi har
8999 en maskinpark som de andre av kommunens skoler bare kan drømme
9004 <p
>Så skjer det som ofte skjer. Det kommer en eller annen
9005 selger/blåruss og skal fikse ALT. I vårt tilfelle betyr dette også
9006 sentralisering av drift. Den ny-ansatte på kommunens IT-avdelingen
9007 skal også ha jobb, og ser for seg å ta over skoledriften. Kommunen
9008 kjøper inn eksterne driftstjenester, og nekter i samme slengen å ta
9009 hensyn til skolen vår. Dette til tross for at vi alene har like mange
9010 datamaskiner som de andre til sammen.
</p
>
9014 <li
>Det blir krevd at vi skal innlemmes i de kommunale systemet, og
9015 det er VI som får ansvar for at dette kommer på plass. Og det er her
9016 de horrible tingene begynner å skje.
</li
>
9018 <li
>Det settes opp en lukket Exchange server som gjør av vi ikke kan
9019 hente epost for våre ansatte. Og det kreves at vi finner løsning på
9022 <li
>Det velges sak arkivsystem som vi pålegges å bruke, noe som gjør
9023 at vi må bruke en terminalløsning mot kommunal server. Ikke i seg selv
9024 et problem i følge IKT-ansvarlig hos oss. Men kommunens IT-avd nektet
9025 faktisk å åpne de porter OSV som vi måtte bruke.
</li
>
9027 <li
>Vi blir pålagt å flytte på innsiden av det kommunale
9028 nettverket. Dette gjorde at vi mistet hjemmekontor for lærere og
9029 elever. Å få åpnet porter i kommunal brannmur var ikke
9030 aktuelt. Mulighet for fjerndrift ble også vekk i samme slengen.
</li
>
9032 <li
>Vår LMS Moodle er ikke mulig å nå for elevene og lærerne.
9036 <p
>Den andre ungdomsskolen i kommunen begynner så å kreve at de skal
9037 få bedre datatetthet, og komme opp på et nivå som ligner det vi
9038 har. De ser at vi kan avholde eksamen hvor alle
10. klassingene får
9039 sitte ved hver sin PC. Og de har fått tilbakemelding (klager) fra VGS
9040 om manglende datakompetanse på elevene som kommer fra dem. Dette fører
9041 videre til at kommunen endelig innser at de må ta grep.
</p
>
9043 <p
>Grepet betyr sentralisering, og farvel til vår plattform får vi
9044 høre. Det blir gjort en rekke bestemmelser og vedtak som vi ikke får
9045 være en del av. Det blir helt klart at vi må redusere antall maskiner,
9046 og det skal satses på bærbare maskiner. Siden vi ikke har fått tatt
9047 del i prosessene som angår oss, så bruker vi fagforening. Vi har ikke
9048 blitt hørt i forbindelse med endringer som er betydelig for vår
9049 hverdag, og greier å stoppe omlegging. I tillegg så har vi et politisk
9050 vedtak i kommunen på at vi skal kjøre Linux på elevnett, og dette
9051 vedtaket kan ikke administrasjonen i kommunene helt uten videre
9052 tilsidesette.
</p
>
9054 <p
>I sum har dette gjort at vi har fått jobbe videre i fred. Og en del
9055 runder i kommunens kontrollutvalg har gjort det tydelig at vi har blitt
9056 systematisk motarbeidet.
</p
>
9058 <p
>I dag har de andre skolene fått sine bærbare maskiner til elever og
9059 lærere, men etter
2 år med innkjøring er det fremdeles problemer

9065 det er for mye arbeid å renske disse for innhold slik at juks ikke er

9074 å komme seg på nett. Og lagring på felles server er bare å glemme i
9075 perioder.

9079 <p
>Vi har slitt mye, kranglet og sloss. Ikke med tekniske problemer,
9080 men med omgivelsene rundt som vil oss til livs. Men det har vært verdt
9081 hver dråpe med svette, og timer med irritasjon. Men vi har begynt å få
9082 rutine her nå.

9088 <li

9125 leserinnlegg myntet på aviser. Disse er ikke sendt til aviser, men
9126 brukt internt i forbindelse med møter med kommune. Vår IKT-ansvarlig
9127 har også truet med å si opp jobben sin hvis det ikke ble tatt hensyn i
9128 større grad enn hva som har vært tilfelle. VI kan også dokumentere
9129 flere brudd på anbudsregler, og vi kjenner til at relativt store
9130 IT-leverandører som ikke har fått tatt del i disse anbudene, rett og
9131 slett ikke tør melde fra av redsel for å få et dårlig rykte.

9133 <p

9135 det vil bare rote til igjen.

9137 <p
>Jeg glemte å nevne at vi nå nesten ikke bruker tid på å drifte
9138 systemet vårt, noe som gjør at det aller meste av tid blir brukt til å
9139 støtte lærerne og elevene. F.eks så bruker vår IKT-ansvarlig den
9140 første timen på jobb,
0730-
0830 kun til å gå ute på arbeidsplassene
9141 til læreren. Dette for å kunne svare på små og store problem, gi tips
9142 og råd, eller bare for å plukke opp hva som er behovet ute i
9143 undervisningsarealene. Det er dessverre ikke slik at alle lærerne har
9144 nok digital kompetanse til å kunne formulere alle spørsmålene de har,
9145 men ved å kunne få vise eller lufte tanker med IKT-ansvarlig så er det
9146 utrolig hva som kommer fram.
</p
>
9150 <li
>Jeg ser at mange bruker økonomi som argument i forhold til å bruke
9151 SkoleLinux, og jeg skal ikke legge skjul på at det var dette som i
9152 utgangspunktet var årsaken til vårt valg. Men diskusjonene og kampen
9153 med kommunens IT-avdeling har gjort at vi har fått et noe annet
9154 fokus. Fordelene med drift og stabilitet, gjør at vi ville ha valgt
9155 samme løsning selv om den var dyrere. At vi slipper langt billigere
9156 unna, som følge av
0,- lisenskostnader og lave maskinvarekostnader, er
9157 bare en bonus.
</li
>
9159 <li
>Etter å ha kranglet oss til å få skikkelig oversikt over hva de
9160 andre skolene i kommunen bruker på IT, så har vi fått gehør for å få
9161 samme midler til innkjøp. Dette har gjort at vi nå kan kjøpe inn
9162 utstyr som de andre skolene bare kan se langt etter. Vi har nettopp
9163 kjøpt inn
3 videokamera i semiproff-klassen for å kunne lage film,
9164 samt sende live fra skoleteater/konserter. Vi har kjøpt inn digitale
9165 kompaktkamera til alle klassene. Vi har et team av lærere som skal i
9166 gang med å teste ut tablets på svake elever. Håpet et at teknologien
9167 kan være med på å gi noen av elevene litt mer motivasjon. Vi har kjøpt
9168 inn et halvt klassesett med pulsklokker, noe som har vist seg å være
9169 overraskende inspirerende for en del av elevene. Vi har også oss på
9170 fag på en høyskole litt lengre sør for oss, slik at
3 av oss nå skal
9171 ta faget
"Linux tjenestedrift
". Som inspektør og en del av skolens
9172 administrasjon er det veldig praktisk å kunne trå til hvis det
9173 kniper. Men IKT-ansvarlig har vært UTROLIG flink til å lage rene
9174 smørbrødlister for hvordan de mest vanlige driftsproblem løses, så det
9175 er lett for flere av oss å ta del i den daglige driften. Vi har svært
9176 stor nytte av lærling (som også hjelper to av naboskolene), men det er
9177 nesten blitt slik at det er om å gjøre å komme til først for å få løse
9178 problem. Det å få fingrene på problem og utfordringer er den aller
9179 beste læremester.
</li
>
9183 <p
>Når vi nå tar til med planlegging av ny skole, så vil det være med
9184 tanke på at det skal være mulig med datautstyr på alle plasser. Vi
9185 kommer i all hovedsak til å legge kabel til alle tenkelige og
9186 utenkelige plasser. WiFi koster tilnærmet NULL å sette opp i
9189 <p
>Vi har ikke vært noe flink til å bidra til SkoleLinux-prosjektet,
9190 vi har rett og slett vært for opptatt med vår egen kamp. Vi har hentet
9191 mye inspirasjon fra diskusjoner som har gått i det miljøet, og vi
9192 håper at vi nå framover kan få tid til å bidra. Vi er i ferd med å
9193 bytte ut en av serverne våre, og da vil denne trolig bli satt opp som
9194 testserver for neste versjon av Skolelinux. På den måten vil vi i alle
9195 fall kunne gi tilbakemeldinger og rapportere feil. I tillegg så vil
9196 det kanskje gi oss noen nye utfordringer, for som lærlingen vår sier:
9197 "Skolelinux er noe herk, det skjer jo ikke noe galt og hvordan skal
9198 jeg da lære?

9227 something fail, I make a note about this in the test matrix and move

9331 Personally, I like VLC, and it is my player of choice when I first try
9332 to play a video file or stream. Only if VLC fail will I drag out
9333 gmplayer to see if it can do better. The reason is mostly the failure
9334 model and trust. When VLC fail, it normally pop up a error message
9335 reporting the problem. When mplayer fail, it normally segfault or
9336 just hangs. The latter failure mode drain my trust in the program.

9339 mplayer in
<a href=
"http://www.skolelinux.org/
">Debian
9340 Edu/Skolelinux
</a
>. The reason is simple. We need a good browser
9341 plugin to play web videos seamlessly, and the VLC browser plugin is
9342 not very good. For example, it lack in-line control buttons, so there
9343 is no way for the user to pause the video. Also, when I
9344 <a href=
"http://wiki.debian.org/DebianEdu/BrowserMultimedia
">last
9345 tested the browser plugins
</a
> available in Debian, the VLC plugin
9346 failed on several video pages where mplayer based plugins worked. If
9347 the browser plugin for VLC was as good as the gecko-mediaplayer
9348 package (which uses mplayer), we would switch.
</P
>
9350 <p
>While VLC is a good player, its user interface is slightly
9351 annoying. The most annoying feature is its inconsistent use of
9352 keyboard shortcuts. When the player is in full screen mode, its
9353 shortcuts are different from when it is playing the video in a window.
9354 For example, space only work as pause when in full screen mode. I
9355 wish it had consisten shortcuts and that space also would work when in
9356 window mode. Another nice shortcut in gmplayer is [enter] to restart
9357 the current video. It is very nice when playing short videos from the
9358 web and want to restart it when new people arrive to have a look at
9359 what is going on.

9815 are virtual machines. And they have been Xen machines running on a
9816 fairly old IBM eserver xseries
345 machine, and we wanted to migrate
9817 them to KVM on a newer Dell PowerEdge
2950 host machine. This was a
9818 bit harder that it could have been, because we set up the Xen virtual
9819 machines to get the virtual partitions from LVM, which as far as I
9820 know is not supported by KVM. So to migrate, we had to convert
9821 several LVM logical volumes to partitions on a virtual disk file.

9828 image partions as devices, and dd to copy the data. I NFS mounted the
9829 new servers storage area on the old server to do the migration.

10129 finally got around to do a test installation of Debian/Squeeze with
10130 kfreebsd. Installation went fairly smooth, thought I noticed some
10131 visual glitches in the cdebconf dialogs (black cursor left on the
10132 screen at random locations). Have not gotten very far with the
10133 testing. Noticed cfdisk did not work, but fdisk did so it was not a
10134 fatal problem. Have to spend some more time on it to see if it is
10135 useful as a file server for NUUG. Will try to find time to set up a
10136 gnash buildbot slave on the Debian Edu/Skolelinux this weekend.

">Skolelinux
</a

10147 supposed provide a school with all the services and user applications
10148 needed on the pupils computer network has always been hard. Even
10149 schools without Internet connections should be able to get Debian Edu
10150 working using this DVD.
</p
>
10152 <p
>The job became a lot harder when apt and aptitude started
10153 installing recommended packages by default. We want the same set of
10154 packages to be installed when using the DVD and the netinst CD, and
10155 that means all recommended packages need to be on the DVD. I created
10156 a patch for debian-cd in
<a href=
"http://bugs.debian.org/
601203">BTS
10157 report #
601203</a
> to do this, and since this change was applied to
10158 the Debian Edu DVD build, we have been seriously short on space.
</p
>
10160 <p
>A few days ago we decided to drop blender, wxmaxima and kicad from
10161 the default installation to save space on the DVD, believing that
10162 those needing these applications are few and can get them from the
10163 Debian archive.
</p
>
10165 <p
>Yesterday, I had a look what source packages to see which packages
10166 were using most space. A few large packages are well know;
10167 openoffice.org, openclipart and fluid-soundfont. But I also
10168 discovered that lilypond used
106 MiB and fglrx-driver used
53 MiB.
10169 The lilypond package is pulled in as a dependency for rosegarden, and
10170 when looking a bit closer I discovered that
99 MiB of the
106 MiB were
10171 the documentation package, which is recommended by the binary package.
10172 I decided to drop this documentation package from our DVD, as most of
10173 our users will use the GUI front-ends and do not need the lilypond
10174 documentation. Similarly, I dropped the non-free fglrx-driver package
10175 which might be installed by d-i when its hardware is detected, as the
10176 free X driver should work.
</p
>
10178 <p
>With this change, we finally got space for the LXDE and Gnome
10179 desktop packages as well as the language specific packages making the
10180 DVD more useful again.

10191 <p
>My
<a href=
"http://pledgebank.com/gnash-avm2
">gnash pledge
</a
> to
10192 raise money for the project is going well. The lower limit of
10
10193 signers was reached in
24 hours, and so far
13 people have signed it.
10194 More signers and more funding is most welcome, and I am really curious
10195 how far we can get before the time limit of December
24 is reached.
10198 <p
>On the #gnash IRC channel on irc.freenode.net, I was just tipped
10199 about what appear to be a great code coverage tool capable of
10200 generating code coverage stats without any changes to the source code.
10202 <a href=

">kcov
</a
>,
10203 and can be used using
<tt
>kcov
&lt;directory
&gt;
&lt;binary
&gt;
</tt
>.
10204 It is missing in Debian, but the git source built just fine in Squeeze
10205 after I installed libelf-dev, libdwarf-dev, pkg-config and
10206 libglib2.0-dev. Failed to build in Lenny, but suspect that is
10207 solvable. I hope kcov make it into Debian soon.
</p

10209 <p
>Finally found time to wrap up the release notes for

10214 release. Give it a try if you need a complete linux solution for your
10215 school, including central infrastructure server, workstations, thin
10216 client servers and diskless workstations. A nice touch added
10217 yesterday is RDP support on the thin client servers, for windows
10218 clients to get a Linux desktop on request.

10229 second most popular used package that is missing in Debian. The sixth
10230 most popular is flashplayer-mozilla. This is a clear indication that
10231 working flash is important for Debian users. Around
10 percent of the
10232 users submitting data to popcon.debian.org have this package
10233 installed.

">Skolelinux

10239 schools experienced with
<a href=
"http://www.skolelinux.org/
">Debian
10240 Edu/Skolelinux
</a
> was the lack of working Flash. A lot of educational
10241 web sites require Flash to work, and lacking working Flash support in
10242 the web browser and the problems with installing it was perceived as a
10243 good reason to stay with Windows.
</p
>
10245 <p
>I once saw a funny and sad comment in a web forum, where Linux was
10246 said to be the retarded cousin that did not really understand
10247 everything you told him but could work fairly well. This was a
10248 comment regarding the problems Linux have with proprietary formats and
10249 non-standard web pages, and is sad because it exposes a fairly common
10250 understanding of whose fault it is if web pages that only work in for
10251 example Internet Explorer
6 fail to work on Firefox, and funny because
10252 it explain very well how annoying it is for users when Linux
10253 distributions do not work with the documents they receive or the web
10254 pages they want to visit.
</p
>
10256 <p
>This is part of the reason why I believe it is important for Debian
10257 and Debian Edu to have a well working Flash implementation in the
10258 distribution, to get at least popular sites as Youtube and Google
10259 Video to working out of the box. For Squeeze, Debian have the chance
10260 to include the latest version of Gnash that will make this happen, as
10261 the new release
0.8.8 was published a few weeks ago and is resting in
10262 unstable. The new version work with more sites that version
0.8.7.
10263 The Gnash maintainers have asked for a freeze exception, but the
10264 release team have not had time to reply to it yet. I hope they agree
10265 with me that Flash is important for the Debian desktop users, and thus
10266 accept the new package into Squeeze.

10308 har vært rullet ut i noen måneder nå, og så vidt jeg fikk vite før

10440 <description><p
>As reported earlier, the last few days I have looked at how Debian
10441 Edu clients are configured, and tried to get rid of all hardcoded
10442 configuration settings on the clients. I believe the work to be
10443 mostly done, and the clients seem to work just fine with dynamically
10444 generated configuration.
</p
>
10446 <p
>What is the point, you might ask? The point is to allow a Debian
10447 Edu desktop to integrate into an existing network infrastructure
10448 without any manual configuration.
</p
>
10450 <p
>This is what happens when installing a Debian Edu client here at
10451 the University of Oslo using PXE. With the PXE installation, I am
10452 asked for language (Norwegian Bokmål), locality (Norway) and keyboard
10453 layout (no-latin1), Debian Edu profile (Roaming Workstation), if I
10454 accept to reformat the hard drive (yes), if I want to submit info to
10455 popcon.debian.org (no) and root password (secret). After answering
10456 these questions, the installer goes ahead and does its thing, and
10457 after around
50 minutes it is done. I press enter to finish the
10458 installation, and the machine reboots into KDE. When the machine is
10459 ready and kdm asks for login information, I enter my university
10460 username and password, am told by kdm that a local home directory has
10461 been created and that I must log in again, and finally log in with the
10462 same username and password to the KDE
4.4 desktop. At no point during
10463 this process did it ask for university specific settings, and all the
10464 required configuration was dynamically detected using information
10465 fetched via DHCP and DNS. The roaming workstation is now ready for
10468 <p
>How was this done, you might wonder? First of all, here is the
10469 list of things that need to be configured on the client to get it
10470 working properly out of the box:
</p
>
10473 <li
>IP address/netmask and DNS server.
</li
>
10474 <li
>Web proxy URL.
</li
>
10475 <li
>LDAP server for NSS directory information (user, group, etc).
</li
>
10476 <li
>Kerberos server for PAM password checking.
</li
>
10477 <li
>SMB mount point to access the network home directory. (*)
</li
>
10478 <li
>Central syslog server to send syslog messages to. (*)
</li
>
10479 <li
>Sitesummary collector URL to submit info to central server. (*)
</li
>
10482 <p
>(Hm, did I forget anything? Let me knew if I did.)
</p
>
10484 <p
>The points marked (*) are not required to be able to use the
10485 machine, but needed to provide central storage and allowing system
10486 administrators to track their machines. Since yesterday, everything
10487 but the sitesummary collector URL is dynamically discovered at boot
10488 and installation time in the svn version of Debian Edu.
</p
>
10490 <p
>The IP and DNS setup is fetched during boot using DHCP as usual.
10491 When a DHCP update arrives, the proxy setup is updated by looking for
10492 http://wpat/wpad.dat and using the content of this WPAD file to
10493 configure the http and ftp proxy in /etc/environment and
10494 /etc/apt/apt.conf. I decided to update the proxy setup using a DHCP
10495 hook to ensure that the client stops using the Debian Edu proxy when
10496 it is moved outside the Debian Edu network, and instead uses any local
10497 proxy present on the new network when it moves around.
</p
>
10499 <p
>The DNS names of the LDAP, Kerberos and syslog server and related
10500 configuration are generated using DNS information at boot. First the
10501 installer looks for a host named ldap in the current DNS domain. If
10502 not found, it looks for _ldap._tcp SRV records in DNS instead. If an
10503 LDAP server is found, its root DSE entry is requested and the
10504 attributes namingContexts and defaultNamingContext are used to
10505 determine which LDAP base to use for NSS. If there are several
10506 namingContexts attibutes and the defaultNamingContext is present, that
10507 LDAP subtree is used as the base. If defaultNamingContext is missing,
10508 the subtrees listed as namingContexts are searched in sequence for any
10509 object with class posixAccount or posixGroup, and the first one with
10510 such an object is used as the LDAP base. For Kerberos, a similar
10511 search is done by first looking for a host named kerberos, and then
10512 for the _kerberos._tcp SRV record. I
've been unable to find a way to
10513 look up the Kerberos realm, so for this the upper case string of the
10514 current DNS domain is used.
</p
>
10516 <p
>For the syslog server, the hosts syslog and loghost are searched
10517 for, and the _syslog._udp SRV record is consulted if no such host is
10518 found. This algorithm works for both Debian Edu and the University of
10519 Oslo. A similar strategy would work for locating the sitesummary
10520 server, but have not been implemented yet. I decided to fetch and
10521 save these settings during installation, to make sure moving to a
10522 different network does not change the set of users being allowed to
10523 log in nor the passwords required to log in. Usernames and passwords
10524 will be cached by sssd when the user logs in on the Debian Edu
10525 network, and will not change as the laptop move around. For a
10526 non-roaming machine, there is no caching, but given that it is
10527 supposed to stay in place it should not matter much. Perhaps we
10528 should switch those to use sssd too?
</p
>
10530 <p
>The user
's SMB mount point for the network home directory is
10531 located when the user logs in for the first time. The LDAP server is
10532 consulted to look for the user
's LDAP object and the sambaHomePath
10533 attribute is used if found. If it isn
't found, the home directory
10534 path fetched from NSS is used instead. Assuming the path is of the
10535 form /site/server/directory/username, the second part is looked up in
10536 DNS and used to generate a SMB URL of the form
10537 smb://server.domain/username. This algorithm works for both Debian
10538 edu and the University of Oslo. Perhaps there are better attributes
10539 to use or a better algorithm that works for more sites, but this will
10540 do for now. :)
</p
>
10542 <p
>This work should make it easier to integrate the Debian Edu clients
10543 into any LDAP/Kerberos infrastructure, and make the current setup even
10544 more flexible than before. I suspect it will also work for thin
10545 client servers, allowing one to easily set up LTSP and hook it into a
10546 existing network infrastructure, but I have not had time to test this
10549 <p
>If you want to help out with implementing these things for Debian
10550 Edu, please contact us on debian-edu@lists.debian.org.
</p
>
10552 <p
>Update
2010-
08-
09: Simon Farnsworth gave me a heads-up on how to
10553 detect Kerberos realm from DNS, by looking for _kerberos TXT entries
10554 before falling back to the upper case DNS domain name. Will have to
10555 implement it for Debian Edu. :)

10564 <description><p
>A few years ago, I was involved in a project planning to use
10565 Windows file servers as home directory servers for Debian
10566 Edu/Skolelinux machines. This was thought to be no problem, as the
10567 access would be through the SMB network file system protocol, and we
10568 knew other sites used SMB with unix and samba as the file server to
10569 mount home directories without any problems. But, after months of
10570 struggling, we had to conclude that our goal was impossible.
</p
>
10572 <p
>The reason is simply that while SMB can be used for home
10573 directories when the file server is Samba running on Unix, this only
10574 work because of Samba have some extensions and the fact that the
10575 underlying file system is a unix file system. When using a Windows
10576 file server, the underlying file system do not have POSIX semantics,
10577 and several programs will fail if the users home directory where they
10578 want to store their configuration lack POSIX semantics.
</p
>
10580 <p
>As part of this work, I wrote a small C program I want to share
10581 with you all, to replicate a few of the problematic applications (like
10582 OpenOffice.org and GCompris) and see if the file system was working as
10583 it should. If you find yourself in spooky file system land, it might

>A few days ago, I
10796 <a href=
"https://people.skolelinux.org/pere/blog/Debian_Edu_roaming_workstation___at_the_university_of_Oslo.html
">tried
10797 to install
</a
> a Roaming workation profile from Debian Edu/Squeeze
10798 while on the university network here at the University of Oslo, and
10799 noticed how much had to change to get it operational using the
10800 university infrastructure. It was fairly easy, but it occured to me
10801 that Debian Edu would improve a lot if I could get the client to
10802 connect without any changes at all, and thus let the client configure
10803 itself during installation and first boot to use the infrastructure
10804 around it. Now I am a huge step further along that road.
</p
>
10806 <p
>With our current squeeze-test packages, I can select the roaming
10807 workstation profile and get a working laptop connecting to the
10808 university LDAP server for user and group and our active directory
10809 servers for Kerberos authentication. All this without any
10810 configuration at all during installation. My users home directory got
10811 a bookmark in the KDE menu to mount it via SMB, with the correct URL.
10812 In short, openldap and sssd is correctly configured. In addition to
10813 this, the client look for http://wpad/wpad.dat to configure a web
10814 proxy, and when it fail to find it no proxy settings are stored in
10815 /etc/environment and /etc/apt/apt.conf. Iceweasel and KDE is
10816 configured to look for the same wpad configuration and also do not use
10817 a proxy when at the university network. If the machine is moved to a
10818 network with such wpad setup, it would automatically use it when DHCP
10819 gave it a IP address.
</p
>
10821 <p
>The LDAP server is located using DNS, by first looking for the DNS
10822 entry ldap.$domain. If this do not exist, it look for the
10823 _ldap._tcp.$domain SRV records and use the first one as the LDAP
10824 server. Next, it connects to the LDAP server and search all
10825 namingContexts entries for posixAccount or posixGroup objects, and
10826 pick the first one as the LDAP base. For Kerberos, a similar
10827 algorithm is used to locate the LDAP server, and the realm is the
10828 uppercase version of $domain.
</p
>
10830 <p
>So, what is not working, you might ask. SMB mounting my home
10831 directory do not work. No idea why, but suspected the incorrect
10832 Kerberos settings in /etc/krb5.conf and /etc/samba/smb.conf might be
10833 the cause. These are not properly configured during installation, and
10834 had to be hand-edited to get the correct Kerberos realm and server,
10835 but SMB mounting still do not work. :(
</p
>
10837 <p
>With this automatic configuration in place, I expect a Debian Edu
10838 roaming profile installation would be able to automatically detect and
10839 connect to any site using LDAP and Kerberos for NSS directory and PAM
10840 authentication. It should also work out of the box in a Active
10841 Directory environment providing posixAccount and posixGroup objects
10842 with UID and GID values.

10855 similar to the laptop setup am I working on using Ubuntu for the
10856 University of Oslo, and just for the heck of it, I tested today how
10857 hard it would be to integrate that profile into the university
10858 infrastructure. In this case, it is the university LDAP server,
10859 Active Directory Kerberos server and SMB mounting from the Netapp file
10862 <p
>I was pleasantly surprised that the only three files needed to be
10863 changed (/etc/sssd/sssd.conf, /etc/ldap.conf and
10864 /etc/mklocaluser.d/
20-debian-edu-config) and one file had to be added
10865 (/usr/share/perl5/Debian/Edu_Local.pm), to get the client working.
10866 Most of the changes were to get the client to use the university LDAP
10867 for NSS and Kerberos server for PAM, but one was to change a hard
10868 coded DNS domain name in the mklocaluser hook from .intern to
10871 <p
>This testing was so encouraging, that I went ahead and adjusted the
10872 Debian Edu scripts and setup in subversion to centralise the roaming
10873 workstation setup a bit more and avoid the hardcoded DNS domain name,
10874 so that when I test this tomorrow, I expect to get away with modifying
10875 only /etc/sssd/sssd.conf and /etc/ldap.conf to get it to use the
10876 university servers.
</p
>
10878 <p
>My goal is to get the clients to have no hardcoded settings and
10879 fetch all their initial setup during installation and first boot, to
10880 allow them to be inserted also into environments where the default
10881 setup in Debian Edu has been changed or as with the university, where
10882 the environment is different but provides the protocols Debian Edu

10893 with the next Debian Edu release. Not nearly done, but one major step
10894 completed.

10897 <p
>This is the first test release based on Squeeze. The focus of this
10898 release is to test the user application selection. To have a look,
10899 install the standalone profile and let the developers know if the set
10900 of installed packages i.e. applications should be modified. If some
10901 user application is missing, or if there are some applications that no
10902 longer make sense to be included in Debian Edu, please let us know.
10903 Also, if a useful application is missing the translation for your
10904 language of choice, please let us know too.
</p

10906 <p
>In addition, feedback and help to polish the desktop (menus,
10907 artwork, starters, etc.) is appreciated. We would like to ship a nice
10908 and handy KDE4 desktop targeted for schools out of the box.

>The last few months me and the other Debian Edu developers have
11012 been working hard to get the Debian/Squeeze based version of Debian
11013 Edu/Skolelinux into shape. This future version will use Kerberos for
11014 authentication, and services are slowly migrated to single signon,
11015 getting rid of password questions one at the time.
</p
>
11017 <p
>It will also feature a roaming workstation profile with local home
11018 directory, for laptops that are only some times on the Skolelinux
11019 network, and for this profile a shortcut is created in Gnome and KDE
11020 to gain access to the users home directory on the file server. This
11021 shortcut uses SMB at the moment, and yesterday I had time to test if
11022 SMB mounting had started working in KDE after we added the cifs-utils
11023 package. I was pleasantly surprised how well it worked.
</p
>
11025 <p
>Thanks to the recent changes to our samba configuration to get it
11026 to use Kerberos for authentication, there were no question about user
11027 password when mounting the SMB volume. A simple click on the shortcut
11028 in the KDE menu, and a window with the home directory popped
11031 <p
>One step closer to a single signon solution out of the box in
11032 Debian Edu. We already had PAM, LDAP, IMAP and SMTP in place, and now
11033 also Samba. Next step is Cups and hopefully also NFS.
</p
>
11035 <p
>We had planned a alpha0 release of Debian Edu for today, but thanks
11036 to the autobuilder administrators for some architectures being slow to
11037 sign packages, we are still missing the fixed LTSP package we need for
11038 the release. It was uploaded three days ago with urgency=high, and if
11039 it had entered testing yesterday we would have been able to test it in
11040 time for a alpha0 release today. As the binaries for ia64 and powerpc
11041 still not uploaded to the Debian archive, we need to delay the alpha
11042 release another day.

11063 LDAP objects, I have had a look at how the packages pdns-backend-ldap

11078 One
"strict

11079 using the same LDAP objects, and a
"tree
" mode where the forward and
11080 reverse entries are in two different subtrees in LDAP with a structure
11081 based on the DNS names, as in tjener.intern and
11082 2.2.0.10.in-addr.arpa.
</p

11084 <p
>In tree mode, the server is set up to use a LDAP subtree as its
11085 base, and uses a
"base

11086 "dc=tjener,dc=intern,

" with a filter for
11089 "(associateddomain=

11090 forward entries, it is looking for attributes named dnsttl, arecord,

11183 <p
>In Debian Edu, we have created DNS objects using the object classes
11184 dcobject (for dc), dnsdomain or dnsdomain2 (structural, for the DNS
11185 attributes) and domainrelatedobject (for associatedDomain). The use
11186 of structural object classes make it impossible to combine these
11187 classes with the object classes used by DHCP.

11189 <p

11190 dnszone structural object class used by Gosa and bind-sdb for the DNS
11191 attributes combined with the domainrelatedobject object class, but in
11192 this case some unused attributes would have to be included as well
11193 (zonename and relativedomainname).

11195 <p

11196 mode and not use any of the existing objectclasses (dnsdomain,
11197 dnsdomain2 and dnszone) when one want to combine the DNS information
11198 with DHCP information, and instead create a auxiliary object class
11199 defined something like this (using the attributes defined for

11304 it possible to group all host entries in a subtree next to the

11319 I guess one could implement ones own schema, as long as the

11373 <description><p
>For a while now, I have wanted to find a way to change the DNS and
11374 DHCP services in Debian Edu to use the same LDAP objects for a given
11375 computer, to avoid the possibility of having a inconsistent state for
11376 a computer in LDAP (as in DHCP but no DNS entry or the other way
11377 around) and make it easier to add computers to LDAP.
</p
>
11379 <p
>I
've looked at how powerdns and dhcpd is using LDAP, and using this
11380 information finally found a solution that seem to work.
</p
>
11382 <p
>The old setup required three LDAP objects for a given computer.
11383 One forward DNS entry, one reverse DNS entry and one DHCP entry. If
11384 we switch powerdns to use its strict LDAP method (ldap-method=strict
11385 in pdns-debian-edu.conf), the forward and reverse DNS entries are
11386 merged into one while making it impossible to transfer the reverse map
11387 to a slave DNS server.
</p
>
11389 <p
>If we also replace the object class used to get the DNS related
11390 attributes to one allowing these attributes to be combined with the
11391 dhcphost object class, we can merge the DNS and DHCP entries into one.
11392 I
've written such object class in the dnsdomainaux.schema file (need
11393 proper OIDs, but that is a minor issue), and tested the setup. It
11394 seem to work.
</p
>
11396 <p
>With this test setup in place, we can get away with one LDAP object
11397 for both DNS and DHCP, and even the LTSP configuration I suggested in
11398 an earlier email. The combined LDAP object will look something like

11419 <p

11420 dhcphost in a different location, to allow us to put the objects

11422 that. If I can
't figure out a way to do that, we can still get rid of
11423 the hosts subtree and move all its content into the DHCP Config tree
11424 (which probably should be renamed to be more related to the new
11425 content. I suspect cn=dnsdhcp,ou=services or something like that
11426 might be a good place to put it.

>Vagrant mentioned on IRC today that ltsp_config now support
11439 sourcing files from /usr/share/ltsp/ltsp_config.d/ on the thin
11440 clients, and that this can be used to fetch configuration from LDAP if
11441 Debian Edu choose to store configuration there.
</p
>
11443 <p
>Armed with this information, I got inspired and wrote a test module
11444 to get configuration from LDAP. The idea is to look up the MAC
11445 address of the client in LDAP, and look for attributes on the form
11446 ltspconfigsetting=value, and use this to export SETTING=value to the
11447 LTSP clients.

11449 <p
>The goal is to be able to store the LTSP configuration attributes
11450 in a
"computer

11451 allowing us to store all information about a computer in one place.
</p

11453 <p

11454 this approach. A real LDAP schema for the ltspClientAux objectclass

11642 <description><p
>For a laptop, centralized user directories and password checking is
11643 a bit troubling. Laptops are typically used also when not connected
11644 to the network, and it is vital for a user to be able to log in or
11645 unlock the screen saver also when a central server is unavailable.
11646 This is possible by caching passwords and directory information (user
11647 and group attributes) locally, and the packages to do so are available
11648 in Debian. Here follow two recipes to set this up in Debian/Squeeze.
11649 It is also possible to set up in Debian/Lenny, but require more manual
11650 setup there because pam-auth-update is missing in Lenny.
</p
>
11652 <h2
>LDAP/Kerberos + nscd + libpam-ccreds + libpam-mklocaluser/pam_mkhomedir
</h2
>
11654 This is the traditional method with a twist. The password caching is
11655 provided by libpam-ccreds (version
10-
4 or later is needed on
11656 Squeeze), and the directory caching is done by nscd. The directory
11657 lookup and password checking is done using LDAP. If one want to use
11658 Kerberos for password checking the libpam-ldapd package can be
11659 replaced with libpam-krb5 or libpam-heimdal. If one is happy having a
11660 local home directory with the path listed in LDAP, one can use the
11661 pam_mkhomedir module from pam-modules to make this happen instead of
11662 using libpam-mklocaluser. A setup for pam-auth-update to enable
11663 pam_mkhomedir will have to be written until a fix for
11664 <a href=
"http://bugs.debian.org/
568577">bug #
568577</a
> is in the
11665 archive. Because I believe it is a bad idea to have local home
11666 directories using misleading paths like /site/server/partition/, I
11667 prefer to create a local user with the home directory in /home/. This
11668 is done using the libpam-mklocaluser package.

>The last few days I have been looking into the status of the LDAP
11849 directory in Debian Edu, and in the process I started to miss a GUI
11850 tool to browse the LDAP tree. The only one I was able to find in
11851 Debian/Squeeze and Lenny is
11852 <a href=
"http://luma.sourceforge.net/
">LUMA
</a
>, which has proved to
11853 be a great tool to get a overview of the current LDAP directory
11854 populated by default in Skolelinux. Thanks to it, I have been able to
11855 find empty and obsolete subtrees, misplaced objects and duplicate
11856 objects. It will be installed by default in Debian/Squeeze. If you
11857 are working with LDAP, give it a go. :)
</p
>
11859 <p
>I did notice one problem with it I have not had time to report to
11860 the BTS yet. There is no .desktop file in the package, so the tool do
11861 not show up in the Gnome and KDE menus, but only deep down in in the
11862 Debian submenu in KDE. I hope that can be fixed before Squeeze is
11863 released.
</p
>
11865 <p
>I have not yet been able to get it to modify the tree yet. I would
11866 like to move objects and remove subtrees directly in the GUI, but have
11867 not found a way to do that with LUMA yet. So in the mean time, I use
11868 <a href=

11874 <a href=
"http://packages.qa.debian.org/g/gq.html
">gq
</a
> package as a
11875 useful GUI alternative. It seem like a good tool, but is unmaintained
11876 in Debian and got a RC bug keeping it out of Squeeze. Unless that
11877 changes, it will not be an option for Debian Edu based on Squeeze.

11892 <p

11893 the dhcpHost object class auxiliary, to allow it to be combined with

11941 I am now testing dist-upgrade of Gnome and KDE in a chroot using both
11942 apt and aptitude, and found their differences interesting. This time
11943 I will only focus on their removal plans.
</p
>
11945 <p
>After installing a Gnome desktop and the laptop task, apt-get wants
11946 to remove
72 packages when dist-upgrading from Lenny to Squeeze. The
11947 surprising part is that it want to remove xorg and all
11948 xserver-xorg-video* drivers. Clearly not a good choice, but I am not
11949 sure why. When asking aptitude to do the same, it want to remove
129
11950 packages, but most of them are library packages I suspect are no
11951 longer needed. Both of them want to remove bluetooth packages, which
11952 I do not know. Perhaps these bluetooth packages are obsolete?
</p
>
11954 <p
>For KDE, apt-get want to remove
82 packages, among them kdebase
11955 which seem like a bad idea and xorg the same way as with Gnome. Asking
11956 aptitude for the same, it wants to remove
192 packages, none which are
11957 too surprising.
</p
>
11959 <p
>I guess the removal of xorg during upgrades should be investigated
11960 and avoided, and perhaps others as well. Here are the complete list
11961 of planned removals. The complete logs is available from the URL
11962 above. Note if you want to repeat these tests, that the upgrade test
11963 for kde+apt-get hung in the tasksel setup because of dpkg asking
11964 conffile questions. No idea why. I worked around it by using
11965 '<tt

12112 <description><p
>The last few days I have done some upgrade testing in Debian, to
12113 see if the upgrade from Lenny to Squeeze will go smoothly. A few bugs
12114 have been discovered and reported in the process
12115 (
<a href=
"http://bugs.debian.org/
585410">#
585410</a
> in nagios3-cgi,
12116 <a href=
"http://bugs.debian.org/
584879">#
584879</a
> already fixed in
12117 enscript and
<a href=
"http://bugs.debian.org/
584861">#
584861</a
> in
12118 kdebase-workspace-data), and to get a more regular testing going on, I
12119 am working on a script to automate the test.
</p
>
12121 <p
>The idea is to create a Lenny chroot and use tasksel to install a
12122 Gnome or KDE desktop installation inside the chroot before upgrading
12123 it. To ensure no services are started in the chroot, a policy-rc.d
12124 script is inserted. To make sure tasksel believe it is to install a
12125 desktop on a laptop, the tasksel tests are replaced in the chroot
12126 (only acceptable because this is a throw-away chroot).
</p
>
12128 <p
>A naive upgrade from Lenny to Squeeze using aptitude dist-upgrade
12129 currently always fail because udev refuses to upgrade with the kernel
12130 in Lenny, so to avoid that problem the file /etc/udev/kernel-upgrade
12131 is created. The bug report
12132 <a href=
"http://bugs.debian.org/
566000">#
566000</a
> make me suspect
12133 this problem do not trigger in a chroot, but I touch the file anyway
12134 to make sure the upgrade go well. Testing on virtual and real
12135 hardware have failed me because of udev so far, and creating this file
12136 do the trick in such settings anyway. This is a
12137 <a href=
"http://www.linuxquestions.org/questions/debian-
26/failed-dist-upgrade-due-to-udev-config_sysfs_deprecated-nonsense-
804130/
">known
12138 issue
</a
> and the current udev behaviour is intended by the udev
12139 maintainer because he lack the resources to rewrite udev to keep
12140 working with old kernels or something like that. I really wish the
12141 udev upstream would keep udev backwards compatible, to avoid such
12142 upgrade problem, but given that they fail to do so, I guess
12143 documenting the way out of this mess is the best option we got for
12144 Debian Squeeze.
</p

12147 script, which I call

12228 packages failing to clean up their obsolete init.d script during
12229 upgrades, and no such problem seem to affect the Gnome desktop+laptop

>Som systemarkitekten bak Skolelinux, kan jeg bare riste på hodet
12270 over påstanden om at Skolelinux krever desentraliserte tjenere.
12271 Skolelinux-arkitekturen er laget for sentralisert drift og plassering
12272 av tjenerne lokalt eller sentralt alt etter behov og nettkapasitet.
12273 Den er modellert på nettverks- og tjenerløsningen som brukes på
12274 Universitetet i Tromsø og Oslo, der jeg jobber med utvikling av
12275 driftstjenester. Dette er det heldigvis noen som har fått med seg, og
12276 jeg er glad for å kunne sitere fra en kommentar på den overnevnte
12277 artikkelen. Min venn og gamle kollega Sturle Sunde forteller der:
12280 <p
>I Flora kommune køyrer vi Skulelinux på skular med alt frå
15 til
12281 meir enn
500 elevar. Dei store skulane har eigen tenar, for det er
12282 mest praktisk. Eg, som er driftsansvarleg for heile nettet, ser
12283 sjeldan dei tenarane fysisk, men at dei står der gjer skulane mindre
12284 avhengige av eksterne linjer som er trege eller dyre. Dei minste
12285 skulane har ikkje eigen tenar. Å bruke sentral tenar er heller ikkje
12286 noko problem. Småskulane klarar seg fint med
1 mbit-linje til ein
12287 sentral tenar eller tenaren på ein større skule.
</p
>
12289 <p
>Det beste med Skulelinux er halvtjukke klientar. Dei treng ikkje
12290 harddisk og brukar minimalt med ressursar på tenaren fordi dei køyrer
12291 programma lokalt. Eit klasserom med
30 sju-åtte år gamle maskiner har
12292 mykje meir CPU og RAM totalt enn nokon moderne tenar til under
12293 millionen. Det trengst to kommandoar på den sentrale tenaren for å
12294 oppdatere alle klientane, både tynne og halvtjukke. Vi har ingen
12295 problem med diskar som ryk heller, som var eit problem før fordi
12296 elevane sat og sparka i maskinene. Og dei krev lite bandbreidde i
12297 nettet, so det er fullt mogleg å køyre slike på småskular med trege
12298 linjer mot tenaren på ein større skule.
</p
>
12300 <p
>Flora kommune har nesten
800 Linux-maskiner i sitt skulenett, og
12301 ein person som tek seg av drift av heile nettet, inkludert tenarar,
12302 klientar, operativsystem, programvare, heimekontorløysing og
12303 administrasjon av brukarar.
</p
>
12305 <p
>No skal det seiast at vi ikkje køyrer rein Skulelinux ut av
12306 boksen. Vi har gjort ein del tilpassingar mot noko Novell-greier som
12307 var der frå før, og som har komplisert installasjonen vår. Etter at
12308 oppsettet var gjort har løysinga vore stabil og kravd minimalt med

12392 problem nvidia video card owners experience and make sure the Debian
12393 distribution work out of the box for these users. The nvidia driver
12394 maintainers expect kdm to be set up to wait longer, while kdm expect
12395 the nvidia driver maintainers to fix the driver to start faster, and
12396 while they wait for each other I guess the users end up switching to a

>A few days ago, parallel booting was enabled in Debian/testing.
12410 The feature seem to hold up pretty well, but three fairly serious
12411 issues are known and should be solved:
12413 <p
><ul

12415 <li
>The wicd package seen to
12416 <a href=

508289">break NFS mounting
</a

12417 <a href=
"http://bugs.debian.org/
581586">network setup
</a
> when
12418 parallel booting is enabled. No idea why, but the wicd maintainer
12419 seem to be on the case.
</li
>
12421 <li
>The nvidia X driver seem to
12422 <a href=
"http://bugs.debian.org/
583312">have a race condition
</a
>
12423 triggered more easily when parallel booting is in effect. The
12424 maintainer is on the case.
</li
>
12426 <li
>The sysv-rc package fail to properly enable dependency based boot
12427 sequencing (the shutdown is broken) when old file-rc users
12428 <a href=
"http://bugs.debian.org/
575080">try to switch back
</a
> to
12429 sysv-rc. One way to solve it would be for file-rc to create
12430 /etc/init.d/.legacy-bootordering, and another is to try to make
12431 sysv-rc more robust. Will investigate some more and probably upload a
12432 workaround in sysv-rc to help those trying to move from file-rc to
12433 sysv-rc get a working shutdown.

>After a long break from debian-installer development, I finally
12457 found time today to return to the project. Having to spend less time
12458 working dependency based boot in debian, as it is almost complete now,
12459 definitely helped freeing some time.
</p
>
12461 <p
>A while back, I ran into a problem while working on Debian Edu. We
12462 include some firmware packages on the Debian Edu CDs, those needed to
12463 get disk and network controllers working. Without having these
12464 firmware packages available during installation, it is impossible to
12465 install Debian Edu on the given machine, and because our target group
12466 are non-technical people, asking them to provide firmware packages on
12467 an external medium is a support pain. Initially, I expected it to be
12468 enough to include the firmware packages on the CD to get
12469 debian-installer to find and use them. This proved to be wrong.
12470 Next, I hoped it was enough to symlink the relevant firmware packages
12471 to some useful location on the CD (tried /cdrom/ and
12472 /cdrom/firmware/). This also proved to not work, and at this point I
12473 found time to look at the debian-installer code to figure out what was
12474 going to work.
</p
>
12476 <p
>The firmware loading code is in the hw-detect package, and a closer
12477 look revealed that it would only look for firmware packages outside
12478 the installation media, so the CD was never checked for firmware
12479 packages. It would only check USB sticks, floppies and other
12480 "external
" media devices. Today I changed it to also look in the
12481 /cdrom/firmware/ directory on the mounted CD or DVD, which should
12482 solve the problem I ran into with Debian edu. I also changed it to
12483 look in /firmware/, to make sure the installer also find firmware
12484 provided in the initrd when booting the installer via PXE, to allow us
12485 to provide the same feature in the PXE setup included in Debian
12488 <p
>To make sure firmware deb packages with a license questions are not
12489 activated without asking if the license is accepted, I extended
12490 hw-detect to look for preinst scripts in the firmware packages, and
12491 run these before activating the firmware during installation. The
12492 license question is asked using debconf in the preinst, so this should
12493 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
12506 Edu finally entered the Debian archive. Today, the new
12507 <a href=
"http://packages.qa.debian.org/libp/libpam-mklocaluser.html
">libpam-mklocaluser
</a
>
12508 package was accepted. Two days ago, two other pieces was accepted
12510 <a href=
"http://packages.qa.debian.org/p/pam-python.html
">pam-python
</a
>
12511 package needed by libpam-mklocaluser, and the
12512 <a href=
"http://packages.qa.debian.org/s/sssd.html
">sssd
</a
> package
12513 passed NEW on Monday. In addition, the
12514 <a href=
"http://packages.qa.debian.org/libp/libpam-ccreds.html
">libpam-ccreds
</a
>
12515 package we need is in experimental (version
10-
4) since Saturday, and
12516 hopefully will be moved to unstable soon.
</p
>
12518 <p
>This collection of packages allow for two different setups for
12519 roaming laptops. The traditional setup would be using libpam-ccreds,
12520 nscd and libpam-mklocaluser with LDAP or Kerberos authentication,
12521 which should work out of the box if the configuration changes proposed
12522 for nscd in
<a href=
"http://bugs.debian.org/
485282">BTS report
12523 #
485282</a
> is implemented. The alternative setup is to use sssd with
12524 libpam-mklocaluser to connect to LDAP or Kerberos and let sssd take
12525 care of the caching of passwords and group information.
</p
>
12527 <p
>I have so far been unable to get sssd to work with the LDAP server
12528 at the University, but suspect the issue is some SSL/GnuTLS related
12529 problem with the server certificate. I plan to update the Debian
12530 package to version
1.2, which is scheduled for next week, and hope to
12531 find time to make sure the next release will include both the
12532 Debian/Ubuntu specific patches. Upstream is friendly and responsive,
12533 and I am sure we will find a good solution.
</p
>
12535 <p
>The idea is to set up the roaming laptops to authenticate using
12536 LDAP or Kerberos and create a local user with home directory in /home/
12537 when a usre in LDAP logs in via KDM or GDM for the first time, and
12538 cache the password for offline checking, as well as caching group
12539 memberhips and other relevant LDAP information. The
12540 libpam-mklocaluser package was created to make sure the local home
12541 directory is in /home/, instead of /site/server/directory/ which would
12542 be the home directory if pam_mkhomedir was used. To avoid confusion
12543 with support requests and configuration, we do not want local laptops
12544 to have users in a path that is used for the same users home directory
12545 on the home directory servers.
</p
>
12547 <p
>One annoying problem with gdm is that it do not show the PAM
12548 message passed to the user from libpam-mklocaluser when the local user
12549 is created. Instead gdm simply reject the login with some generic
12550 message. The message is shown in kdm, ssh and login, so I guess it is
12551 a bug in gdm. Have not investigated if there is some other message
12552 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
12710 Debian Edu. The Debian Edu infrastructure is mostly designed to
12711 handle stationary computers, and less suited for computers that come
12714 <p
>Now I finally believe I have an sensible idea on how to adjust
12715 Debian Edu for laptops, by introducing a new profile for them, for
12716 example called Roaming Workstations. Here are my thought on this.
12717 The setup would consist of the following:
</p
>
12721 <li
>During installation, the user name of the owner / primary user of
12722 the laptop is requested and a local home directory is set up for
12723 the user, with uid and gid information fetched from the LDAP
12724 server. This allow the user to work also when offline. The
12725 central home directory can be available in a subdirectory on
12726 request, for example mounted via CIFS. It could be mounted
12727 automatically when a user log in while on the Debian Edu network,
12728 and unmounted when the machine is taken away (network down,
12729 hibernate, etc), it can be set up to do automatic mounting on
12730 request (using autofs), or perhaps some GUI button on the desktop
12731 can be used to access it when needed. Perhaps it is enough to use
12732 the fish protocol in KDE?
</li
>
12734 <li
>Password checking is set up to use LDAP or Kerberos
12735 authentication when the machine is on the Debian Edu network, and
12736 to cache the password for offline checking when the machine unable
12737 to reach the LDAP or Kerberos server. This can be done using
12738 <a href=
"http://www.padl.com/OSS/pam_ccreds.html
">libpam-ccreds
</a
>
12739 or the Fedora developed
12740 <a href=
"https://fedoraproject.org/wiki/Features/SSSD
">System
12741 Security Services Daemon
</a
> packages.
</li
>
12743 <li
>File synchronisation with the central home directory is set up
12744 using a shared directory in both the local and the central home
12745 directory, using unison.
</li
>
12747 <li
>Printing should be set up to print to all printers broadcasting
12748 their existence on the local network, and should then work out of
12749 the box with CUPS. For sites needing accurate printer quotas, some
12750 system with Kerberos authentication or printing via ssh could be
12751 implemented.
</li
>
12753 <li
>For users that should have local root access to their laptop,
12754 sudo should be used to allow this to the local user.
</li
>
12756 <li
>It would be nice if user and group information from LDAP is
12757 cached on the client, but given that there are entries for the
12758 local user and primary group in /etc/, it should not be needed.
</li
>
12762 <p
>I believe all the pieces to implement this are in Debian/testing at
12763 the moment. If we work quickly, we should be able to get this ready
12764 in time for the Squeeze release to freeze. Some of the pieces need
12765 tweaking, like libpam-ccreds should get support for pam-auth-update
12766 (
<a href=
"http://bugs.debian.org/
566718">#
566718</a
>) and nslcd (or
12767 perhaps debian-edu-config) should get some integration code to stop
12768 its daemon when the LDAP server is unavailable to avoid long timeouts
12769 when disconnected from the net. If we get Kerberos enabled, we need
12770 to make sure we avoid long timeouts there too.

12783 NUUG presentation
</a
> about Kerberos was inspiring, and reminded me
12784 about the need to start using Kerberos in Skolelinux. Setting up a
12785 Kerberos server seem to be straight forward, and if we get this in
12786 place a long time before the Squeeze version of Debian freezes, we
12787 have a chance to migrate Skolelinux away from NFSv3 for the home
12788 directories, and over to an architecture where the infrastructure do
12789 not have to trust IP addresses and machines, and instead can trust
12790 users and cryptographic keys instead.
</p
>
12792 <p
>A challenge will be integration and administration. Is there a
12793 Kerberos implementation for Debian where one can control the
12794 administration access in Kerberos using LDAP groups? With it, the
12795 school administration will have to maintain access control using flat
12796 files on the main server, which give a huge potential for errors.
</p
>
12798 <p
>A related question I would like to know is how well Kerberos and
12799 pam-ccreds (offline password check) work together. Anyone know?
</p
>
12801 <p
>Next step will be to use Kerberos for access control in Lwat and
12802 Nagios. I have no idea how much work that will be to implement. We
12803 would also need to document how to integrate with Windows AD, as such
12804 shared network will require two Kerberos realms that need to cooperate
12805 to work properly.
</p
>
12807 <p
>I believe a good start would be to start using Kerberos on the
12808 skolelinux.no machines, and this way get ourselves experience with
12809 configuration and integration. A natural starting point would be
12810 setting up ldap.skolelinux.no as the Kerberos server, and migrate the
12811 rest of the machines from PAM via LDAP to PAM via Kerberos one at the
12814 <p
>If you would like to contribute to get this working in Skolelinux,
12815 I recommend you to see the video recording from yesterdays NUUG
12816 presentation, and start using Kerberos at home. The video show show
12817 up in a few days.

>6 years ago, as part of the Debian Edu development I am involved
12827 in, I asked for a hook in the kdm and gdm setup to run scripts as root
12828 when the user log out. A bug was submitted against the xfree86-common
12829 package in
2004 (
<a href=
"http://bugs.debian.org/
230422">#
230422</a
>),
12830 and revisited every time Debian Edu was working on a new release.
12831 Today, this finally paid off.
</p
>
12833 <p
>The framework for this feature was today commited to the git
12834 repositry for the xorg package, and the git repository for xdm has
12835 been updated to use this framework. Next on my agenda is to make sure
12836 kdm and gdm also add code to use this framework.
</p
>
12838 <p
>In Debian Edu, we want to ability to run commands as root when the
12839 user log out, to get rid of runaway processes and do general cleanup
12840 after a user. With this framework in place, we finally can do that in
12841 a generic way that work with all display managers using this
12842 framework. My goal is to get all display managers in Debian use it,
12843 similar to how they use the Xsession.d framework today.

>One of the new features in the next Debian/Lenny based release of
12875 Debian Edu/Skolelinux, which is scheduled for release in the next few
12876 days, is automatic configuration of the service monitoring system
12877 Nagios. The previous release had automatic configuration of trend
12878 analysis using Munin, and this Lenny based release take that a step
12881 <p
>When installing a Debian Edu Main-server, it is automatically
12882 configured as a Munin and Nagios server. In addition, it is
12883 configured to be a server for the
12884 <a href=
"http://wiki.debian.org/DebianEdu/HowTo/SiteSummary
">SiteSummary
12885 system
</a
> I have written for use in Debian Edu. The SiteSummary
12886 system is inspired by a system used by the University of Oslo where I
12887 work. In short, the system provide a centralised collector of
12888 information about the computers on the network, and a client on each
12889 computer submitting information to this collector. This allow for
12890 automatic information on which packages are installed on each machine,
12891 which kernel the machines are using, what kind of configuration the
12892 packages got etc. This also allow us to automatically generate Munin
12893 and Nagios configuration.
</p
>
12895 <p
>All computers reporting to the sitesummary collector with the
12896 munin-node package installed is automatically enabled as a Munin
12897 client and graphs from the statistics collected from that machine show
12898 up automatically on http://www/munin/ on the Main-server.
</p
>
12900 <p
>All non-laptop computers reporting to the sitesummary collector are
12901 automatically monitored for network presence (ping and any network
12902 services detected). In addition, all computers (also laptops) with
12903 the nagios-nrpe-server package installed and configured the way
12904 sitesummary would configure it, are monitored for full disks, software
12905 raid status, swap free and other checks that need to run locally on
12906 the machine.
</p
>
12908 <p
>The result is that the administrator on a school using Debian Edu
12909 based on Lenny will be able to check the health of his installation
12910 with one look at the Nagios settings, without having to spend any time
12911 keeping the Nagios configuration up-to-date.
</p
>
12913 <p
>The only configuration one need to do to get Nagios up and running
12914 is to set the password used to get access via HTTP. The system
12915 administrator need to run
"<tt
>htpasswd /etc/nagios3/htpasswd.users
12916 nagiosadmin
</tt
>" to create a nagiosadmin user and set a password for
12917 it to be able to log into the Nagios web pages. After that,
12918 everything is taken care of.

"Teach the Teacher

12932 å få fri programvare og unix-lignende operativsystemer inn i Skolen.

12934 mulighet til å møte en bedre IT-hverdag. Jeg var tilstede på
12935 møtet, og hadde sans for ideen, men intet skjedde. På vårparten
12936 2001 ble det arrangert en demonstrasjon i anledning at First Tuesday
12937 hadde invitert Microsoft til et møte for å fortelle om fremtidens
12938 Internet. Dette provoserte endel av oss, og EFN og NUUG tok initiativ

12943 Etter demonstrasjonen arrangerte Håkon en fest hjemme hos seg der alle
12944 som hadde vært aktive i demonstrasjonsplanlegging og gjennomføringen
12945 deltok. Før festen var jeg blitt lei av å vente på at Håkon skulle ta
12946 initiativ til

12947 besteme jeg meg for å benytte anledningen hos Håkon til å snakke om
12948 behovet for å hjelpe skolene i gang med bedre datasystemer bestående
12949 av fri programvare og unix-lignende operativsystemer. Flere var
12950 interessert, og Knut Yrvin tenkte på ideen. Han

12988 Edu/Skolelinux development gathering. I got a bit done tuning the
12989 desktop, and looked into the dynamic service location protocol
12990 implementation avahi. It look like it could be useful for us. Almost
12991 30 people participated, and I believe it was a great environment to
12992 get to know the Skolelinux system. Walter Bender, involved in the
12993 development of the Sugar educational platform, presented his stuff and
12994 also helped me improve my OLPC installation. He also showed me that
12995 his Turtle Art application can be used in standalone mode, and we
12996 agreed that I would help getting it packaged for Debian. As a
12997 standalone application it would be great for Debian Edu. We also
12998 tried to get the video conferencing working with two OLPCs, but that
12999 proved to be too hard for us. The application seem to need more work

13126 control buttons to pause or stop the video, and capable of streaming
13127 all the multimedia content available on the web. The test results and
13128 notes are available on
13129 <a href=
"http://wiki.debian.org/DebianEdu/BrowserMultimedia
">the
13130 Debian wiki
</a
>. I was surprised how few of the plugins are able to
13131 fill this need. My personal video player favorite, VLC, has a really
13132 bad plugin which fail on a lot of the test pages. A lot of the MIME
13133 types I would expect to work with any free software player (like
13134 video/ogg), just do not work. And simple formats like the
13135 audio/x-mplegurl format (m3u playlists), just isn
't supported by the
13136 totem and vlc plugins. I hope the situation will improve soon. No
13137 wonder sites use the proprietary Adobe flash to play video.
