>Two years ago, I did some experiments with eatmydata and the Debian
15 installation system, observing how using
16 <a href=
"http://people.skolelinux.org/pere/blog/Speeding_up_the_Debian_installer_using_eatmydata_and_dpkg_divert.html
">eatmydata
17 could speed up the installation
</a
> quite a bit. My testing measured
18 speedup around
20-
40 percent for Debian Edu, where we install around
19 1000 packages from within the installer. The eatmydata package
20 provide a way to disable/delay file system flushing. This is a bit
21 risky in the general case, as files that should be stored on disk will
22 stay only in memory a bit longer than expected, causing problems if a
23 machine crashes at an inconvenient time. But for an installation, if
24 the machine crashes during installation the process is normally
25 restarted, and avoiding disk operations as much as possible to speed
26 up the process make perfect sense.
28 <p
>I added code in the Debian Edu specific installation code to enable
29 <a href=
"https://tracker.debian.org/pkg/libeatmydata
">eatmydata
</a
>,
30 but did not have time to push it any further. But a few months ago I
31 picked it up again and worked with the libeatmydata package maintainer
32 Mattia Rizzolo to make it easier for everyone to get this installation
33 speedup in Debian. Thanks to our cooperation There is now an
34 eatmydata-udeb package in Debian testing and unstable, and simply
35 enabling/installing it in debian-installer (d-i) is enough to get the
36 quicker installations. It can be enabled using preseeding. The
37 following untested kernel argument should do the trick:
</p
>
39 <blockquote
><pre
>
40 preseed/early_command=
"anna-install eatmydata-udeb
"
41 </pre
></blockquote
>
43 <p
>This should ask d-i to install the package inside the d-i
44 environment early in the installation sequence. Having it installed
45 in d-i in turn will make sure the relevant scripts are called just
46 after debootstrap filled /target/ with the freshly installed Debian
47 system to configure apt to run dpkg with eatmydata. This is enough to
48 speed up the installation process. There is a proposal to
49 <a href=
"https://bugs.debian.org/
841153">extend the idea a bit further
50 by using /etc/ld.so.preload instead of apt.conf
</a
>, but I have not
51 tested its impact.

63 multimedia player in Debian claimed to support most file formats /
64 MIME types
</a

65 the various players claimed support for. The range was from
55 to
130
66 MIME types. I suspect most media formats are supported by all
67 players, but this is not really reflected in the MimeTypes values in
68 their desktop files. There are probably also some bogus MIME types
69 listed, but it is hard to identify which one this is.
</p

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

81 kmplayer. I am sure some of the other players desktop files support
82 several of the formats currently listed as working only with vlc,
83 toten and parole.

85 <p
>A sad observation is that only
14 MIME types are listed as
86 supported by all the tested multimedia players in Debian in their
87 desktop files: audio/mpeg, audio/vnd.rn-realaudio, audio/x-mpegurl,
88 audio/x-ms-wma, audio/x-scpls, audio/x-wav, video/mp4, video/mpeg,
89 video/quicktime, video/vnd.rn-realvideo, video/x-matroska,
90 video/x-ms-asf, video/x-ms-wmv and video/x-msvideo. Personally I find
91 it sad that video/ogg and video/webm is not supported by all the media

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

112 not been updated for a while. But browser plugins are less relevant
113 these days, so I thought it was time to look at standalone
116 <p
>A few days ago I was tired of VLC not being listed as a viable
117 player when I wanted to play videos from the Norwegian National
118 Broadcasting Company, and decided to investigate why. The cause is a
119 <a href=
"https://bugs.debian.org/
822245">missing MIME type in the VLC
120 desktop file
</a
>. In the process I wrote a script to compare the set
121 of MIME types announced in the desktop file and the browser plugin,
122 only to discover that there is quite a large difference between the
123 two for VLC. This discovery made me dig up the script I used to
124 compare browser plugins, and adjust it to compare desktop files
125 instead, to try to figure out which multimedia player in Debian
126 support most file formats.

225 imply, public domain and permissively licensed software can lead to
226 the production of more proprietary software as people discover useful
227 software, extend it and or incorporate it into their hardware or
228 software products. Copyleft licenses such as the GNU GPL were created
229 to close off this avenue to the production of proprietary software but
230 such licenses are not enough. With the ongoing adoption of Free
231 Software by individuals and groups, inevitably the community
's
232 expectations of license compliance are violated, usually out of
233 ignorance of the way Free Software works, but not always. As Karen

449 == About Debian Edu / Skolelinux ==
451 Debian Edu, also known as Skolelinux, is a Linux distribution based on
452 Debian providing an out-of-the box environment of a completely
453 configured school network. Directly after installation a school server
454 running all services needed for a school network is set up just
455 waiting for users and machines being added via GOsa², a comfortable
456 Web-UI. A netbooting environment is prepared using PXE, so after
457 initial installation of the main server from CD or USB stick all other
458 machines can be installed via the network. The provided school server
459 provides LDAP database and Kerberos authentication service,
460 centralized home directories, DHCP server, web proxy and many other
461 services. The desktop contains more than
60 educational software
462 packages and more are available from the Debian archive, and schools
463 can choose between KDE, GNOME, LXDE, Xfce and MATE desktop
468 The Debian Project was founded in
1993 by Ian Murdock to be a truly
469 free community project. Since then the project has grown to be one of
470 the largest and most influential open source projects. Thousands of
471 volunteers from all over the world work together to create and
472 maintain Debian software. Available in
70 languages, and supporting a
473 huge range of computer types, Debian calls itself the universal
478 Thanks to everyone making Debian and Debian Edu / Skolelinux happen!

>It was a surprise to me to learn that project to create a complete
490 computer system for schools I
've involved in,
491 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>, was
492 being used in India. But apparently it is, and I managed to get an
493 interview with one of the friends of the project there, Shirish
496 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
498 <p
>My name is Shirish Agarwal. Based out of the educational and
499 historical city of Pune, from the western state of Maharashtra, India.
500 My bread comes from giving training, giving policy tips,
501 installations on free software to mom and pop shops in different
502 fields from Desktop publishing to retail shops as well as work with
503 few software start-ups as well.
</p
>
505 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
506 project?
</strong
></p
>
508 <p
>It started innocently enough. I have been using Debian for a few
509 years and in one local minidebconf / debutsav I was asked if there was
510 anything for schools or education. I had worked / played with free
511 educational softwares such as Gcompris and Stellarium for my many
512 nieces and nephews so researched and found Debian Edu or Skolelinux as
513 it was known then. Since then I have started using the various
514 education meta-packages provided by the project.
</p
>
516 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
517 Edu?
</strong
></p
>
519 <p
>It
's closest I have seen where a package full of educational
520 software are packed, which are free and open (both literally and
521 figuratively). Even if I take the simplest software which is
522 gcompris, the number of activities therein are amazing. Another one of
523 the softwares that I have liked for a long time is stellarium. Even
524 pysycache is cool except for couple of issues I encountered
525 <a href=
"https://bugs.debian.org/
781841">#
781841</a
> and
526 <a href=
"https://bugs.debian.org/
781842">#
781842</a
>.
</p
>
528 <p
>I prefer software installed on the system over web based solutions,
529 as a web site can disappear any time but the software on disk has the
530 possibility of a larger life span. Of course with both it
's more a
531 question if it has enough users who make it fun or sustainable or both
532 for the developer per-se.
</p
>
534 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
535 Edu?
</strong
></p
>
537 <p
>I do see that the Debian Edu team seems to be short-handed and I
538 think more efforts should be made to make it popular and ask and take
539 help from people and the larger community wherever possible.
</p
>
541 <p
>I don
't see any disadvantage to use Skolelinux apart from the fact
542 that most apps. are generic which is good or bad how you see it.
543 However, saying that I do acknowledge the fact that the canvas is
544 pretty big and there are lot of interesting ideas that could be done
545 but for reasons not known not done or if done I don
't know about them.
546 Let me share some of the ideas (these are more upstream based but
547 still) I have had for a long time :
</p
>
549 <p
>1. Classical maths question of two trains in opposing directions
550 each running @x kmph/mph at y distance, when they will meet and how
551 far would each travel and similar questions like these.
553 <p
>The computer is a fantastic system where questions like these can
554 be drawn, animated and the methodology and answers teased out in
555 interactive manner. While sites such as the
556 <a href=
"http://mathforum.org/dr.math/faq/faq.two.trains.html
">Ask
557 Dr. Math FAQ on The Two Trains problem
</a
> (as an example or point of
558 inspiration) can be used there is lot more that can be done. I dunno
559 if there is a free software which does something like this. The idea
560 being a blend of objects + animation + interaction which does
561 this. The whole interaction could be gamified with points or sounds or
562 colourful celebration whenever the user gets even part of the question
563 or/and methodology right. That would help reinforce good behaviour.
564 This understanding could be used to share/showcase everything from how
565 the first wheel came to be, to evolution to how astronomy started,
566 psychics and everything in-between.
</p
>
568 <p
>One specific idea in the train part was having the Linux mascot on
569 one train and the BSD or GNU mascot on the other train and they
570 meeting somewhere in-between. Characters from blender movies could
571 also be used.
</p
>
573 <p
>2. Loads of crossword-puzzles with reference to subjects: We have
574 enormous data sets in Wikipedia and Wikitionary. I don
't think it
575 should be a big job to design crossword puzzles. Using categories and
576 sub-categories it should be doable to have Q
&A single word answers
577 from the existing data-sets. What would make it easy or hard could be
578 the length of the word + existence of many or few vowels depending on
579 the user
's input.
</p
>
581 <p
>3. Jigsaw puzzles - We already have a great software called
582 palapeli with number of slicers making it pretty interesting. What
583 needs to be done is to download large number of public domain and
584 copyleft images, tease and use IPTC tags to categorise them into
585 nature, history etc. and let it loose. This could turn to be really
586 huge collection of images. One source could be taken from
587 commons.wikimedia.org, others could be huge collection of royalty-free
588 stock photos. Potential is immense.
</p
>
590 <p
>Apart from this, free software suffers in two directions, we lag
591 both in development (of using new features per-se) and maintenance a
592 lot. This is more so in educational software as these applications
593 need to be timely and the opportunity cost of missing deadlines is
594 immense. If we are able to solve issues of funding for development and
595 maintenance of such software I don
't see any big difficulties. I know
596 of few start-ups in and around India who would love to develop and
597 maintain such software if funding issues could be solved.
</p
>
599 <p
><strong
>Which free software do you use daily?
</strong
></p
>
601 <p
>That would be huge list. Some of the softwares are obviously apt,
602 aptitude, debdelta, leafpad, the shell of course (zsh nowadays),
603 quassel for IRC. In games I use shisen-sho while card-games are evenly
604 between kpat and Aiselriot. In desktops it
's a tie between
605 gnome-flashback and mate.
</p
>
607 <p
><strong
>Which strategy do you believe is the right one to use to
608 get schools to use free software?
</strong
></p
>
610 <p
>I think it should first start with using specific FOSS apps. in
611 whatever environment they are. If it
's MS-Windows or Mac so be it.
612 Once they are habitual with the apps. and there is buy-in from the
613 school management then it could be installed anywhere. Most of the
614 people now understand the concept of a repository because of the
615 various online stores so it isn
't hard to convince on that front.
</p
>
617 <p
>What is harder is having enough people with technical skills and
618 passion to service them. If you get buy-in from one or two teachers
619 then ideas like above could also be asked to be done as a project as
622 <p
>I think where we fall short more than anything is in marketing. For
623 instance, Debian has this whole range of fonts in its archive but
624 there isn
't even a page where all those different fonts in the La
625 Ipsum format could be tried out for newcomers.
</p
>
627 <p
>One of the issues faced constantly in installations is with updates
628 and upgrades. People have this myth that each update and upgrade
629 means the user interface will / has to change. I have seen this
630 innumerable times. That perhaps is one of the reasons which browsers
631 like Iceweasel / Firefox change user interfaces so much, not because
632 it might be needed or be functional but because people believe that
633 changed user interfaces are better. This, can easily be pointed with
634 the user interfaces changed with almost every MS-Windows and Mac OS
637 <p
>The problems with Debian Edu for deployment are many. The biggest
638 is the huge gap between what is taught in schools and what Debian Edu
641 <p
>Me and my friends did teach on week-ends in a government school for
643 <a href=
"https://flossexperiences.wordpress.com/
2012/
10/
08/sharings/
">gathered
644 some experience
</a
> there. Some of the things we learnt/discovered
645 there was :
</p
>
649 <li
>Most of the teachers are very territorial about their subjects
650 and they do not want you to teach anything out of the
651 portion/syllabus given.
</li
>
653 <li
>They want any activity on the system in accordance to whatever
654 is in the syllabus.
</li
>
656 <li
>There are huge barriers both with the English language and at
657 times with objects or whatever. An example, let
's say in gcompris
658 you have objects falling down and you have to name them and let
's
659 say the falling object is a hat or a fedora hat, this would not be
660 as recognizable as say a
661 <a href=
"https://en.wikipedia.org/wiki/Puneri_Pagadi
">Puneri
662 Pagdi
</a
> so there is need to inject local objects, words wherever
663 possible. Especially for word-games there are so many hindi words
664 which have become part of english vocabulary (for instance in
665 parley), those could be made into a hinglish collection or
666 something but that is something for upstream to do.

877 but it is possible to work around these to get anyway. Here is a
878 recipe on how to get the installation limping along.
</p

880 <p
>First, download the test ISO via

1.iso).
885 The ISO build was broken on Tuesday, so we do not get a new ISO every
886 12 hours or so, but thankfully the ISO we already got we are able to
887 install with some tweaking.

>The
<a href=
"https://www.debian.org/
">Debian
</a

937 a lot quicker. When we install more than
2000 packages in
938 <a href=
"http://www.skolelinux.org/
">Skolelinux / Debian Edu
</a
> using
939 tasksel in the installer, unpacking the binary packages take forever.
940 A part of the slow I/O issue was discussed in
941 <a href=
"https://bugs.debian.org/
613428">bug #
613428</a
> about too
942 much file system sync-ing done by dpkg, which is the package
943 responsible for unpacking the binary packages. Other parts (like code
944 executed by postinst scripts) might also sync to disk during
945 installation. All this sync-ing to disk do not really make sense to
946 me. If the machine crash half-way through, I start over, I do not try
947 to salvage the half installed system. So the failure sync-ing is
948 supposed to protect against, hardware or system crash, is not really
949 relevant while the installer is running.
</p
>
951 <p
>A few days ago, I thought of a way to get rid of all the file
952 system sync()-ing in a fairly non-intrusive way, without the need to
953 change the code in several packages. The idea is not new, but I have
954 not heard anyone propose the approach using dpkg-divert before. It
955 depend on the small and clever package
956 <a href=
"https://packages.qa.debian.org/eatmydata
">eatmydata
</a
>, which
957 uses LD_PRELOAD to replace the system functions for syncing data to
958 disk with functions doing nothing, thus allowing programs to live
959 dangerous while speeding up disk I/O significantly. Instead of
960 modifying the implementation of dpkg, apt and tasksel (which are the
961 packages responsible for selecting, fetching and installing packages),
962 it occurred to me that we could just divert the programs away, replace
963 them with a simple shell wrapper calling
964 "eatmydata
&nbsp;$program
&nbsp;$@
", to get the same effect.
965 Two days ago I decided to test the idea, and wrapped up a simple
966 implementation for the Debian Edu udeb.
</p
>
968 <p
>The effect was stunning. In my first test it reduced the running
969 time of the pkgsel step (installing tasks) from
64 to less than
44
970 minutes (
20 minutes shaved off the installation) on an old Dell
971 Latitude D505 machine. I am not quite sure what the optimised time
972 would have been, as I messed up the testing a bit, causing the debconf
973 priority to get low enough for two questions to pop up during
974 installation. As soon as I saw the questions I moved the installation
975 along, but do not know how long the question were holding up the
976 installation. I did some more measurements using Debian Edu Jessie,
977 and got these results. The time measured is the time stamp in
978 /var/log/syslog between the
"pkgsel: starting tasksel
" and the
979 "pkgsel: finishing up
" lines, if you want to do the same measurement
980 yourself. In Debian Edu, the tasksel dialog do not show up, and the
981 timing thus do not depend on how quickly the user handle the tasksel

1030 <p
>The test is done using a netinst ISO on a USB stick, so some of the
1031 time is spent downloading packages. The connection to the Internet
1032 was
100Mbit/s during testing, so downloading should not be a
1033 significant factor in the measurement. Download typically took a few
1034 seconds to a few minutes, depending on the amount of packages being
1035 installed.
</p
>
1037 <p
>The speedup is implemented by using two hooks in
1038 <a href=
"https://www.debian.org/devel/debian-installer/
">Debian
1039 Installer
</a
>, the pre-pkgsel.d hook to set up the diverts, and the
1040 finish-install.d hook to remove the divert at the end of the
1041 installation. I picked the pre-pkgsel.d hook instead of the
1042 post-base-installer.d hook because I test using an ISO without the
1043 eatmydata package included, and the post-base-installer.d hook in
1044 Debian Edu can only operate on packages included in the ISO. The
1045 negative effect of this is that I am unable to activate this
1046 optimization for the kernel installation step in d-i. If the code is
1047 moved to the post-base-installer.d hook, the speedup would be larger
1048 for the entire installation.
</p

1050 <p
>I
've implemented this in the
1051 <a href=
"https://packages.qa.debian.org/debian-edu-install
">debian-edu-install
</a
>
1052 git repository, and plan to provide the optimization as part of the
1053 Debian Edu installation. If you want to test this yourself, you can
1054 create two files in the installer (or in an udeb). One shell script
1055 need do go into /usr/lib/pre-pkgsel.d/, with content like this:

1128 guess we will see if the change is safe after some more testing.
1129 Perhaps there is some package in Debian depending on sync() and
1130 fsync() having effect? Perhaps it should go into its own udeb, to
1131 allow those of us wanting to enable it to do so without affecting
1134 <p

2014-

24: Since a few days ago, enabling this optimization

17: The bug mentioned above is fixed in testing and
1140 the optimization work again. And I have discovered that the

1142 simpler approach as part of the debian-edu-install package. See

1161 involved is Bernd Zeitzen, who show up on the project mailing lists
1162 from time to time with interesting questions and tips on how to adjust
1163 the setup. I managed to interview him this summer.

>My name is Bernd Zeitzen and I
'm married with Hedda, a self
1168 employed physiotherapist. My former profession is tool maker, but I
1169 haven
't worked for
30 years in this job.
30 years ago I started to
1170 support my wife and become her officeworker and a few years later the
1171 administrator for a small computer network, today based on Ubuntu
1172 Server (Samba, OpenVPN). For her daily work she has to use Windows
1173 Desktops because the software she needs to organize her business only
1174 works with Windows . :-(
</p
>
1176 <p
>In
1988 we started with one PC and DOS, then I learned to use
1177 Windows
98,
2000, XP, …,
8, Ubuntu, MacOSX. Today we are running a
1178 Linux server with
6 Windows clients and
10 persons (teacher of
1179 children with special needs, speech therapist, occupational therapist,
1180 psychologist and officeworkers) using our Samba shares via OpenVPN to
1181 work with the documentations of our patients.

>How did you get in contact with the Skolelinux / Debian Edu
1184 project?
</strong

1186 <p
>Two years ago a friend of mine asked me, if I want to get a job in
1187 his school (
<a href=
"http://www.gymnasium-harsewinkel.de/
">Gymnasium
1188 Harsewinkel
</a
>). They started with Skolelinux / Debian Edu and they
1189 were looking for people to give support to the teachers using the
1190 software and the network and teaching the pupils increasing their
1191 computer skills in optional lessons. I
'm spending
4-
6 hours a week
1192 with this job.

1197 <p
>The independence.
</p
>
1199 <p
>First: Every person is allowed to use, share and develop the
1200 software. Even if you are poor, you are allowed to use the software
1201 included in Skolelinux/Debian Edu and all the other Free Software.
</p
>
1203 <p
>Second: The software runs on old machines and this gives us the
1204 possibility to recycle computers, weeded out from offices. The
1205 servers and desktops are running for more than two years and they are
1206 working reliable.
</p
>
1208 <p
>We have two servers (one tjener and one terminal server),
45
1209 workstations in three classrooms and seven laptops as a mobile
1210 solution for all classrooms. These machines are all booting from the
1211 terminal server. In the moment we are installing
30 laptops as mobile
1212 workstations. Then the pupils have the possibility to work with these
1213 machines in their classrooms. Internet access is realized by a WLAN
1214 router, connected to the schools network. This is all done without a
1215 dedicated system administrator or a computer science teacher.

1232 <p
>In Germany we have the situation: every school is free to decide
1233 which software they want to use. This decision is influenced by
1234 teachers who learned to use Windows and MS Office. They buy a PC with
1235 Windows preinstalled and an additional testing version of MS
1236 Office. They don
't know about the possibility to use Free Software
1237 instead. Another problem are the publisher of school books. They
1238 develop their software, added to the school books, for Windows.

1248 project
</a
> provide an instruction manual for teachers, system
1249 administrators and other users that contain useful tips for setting up
1250 and maintaining a Debian Edu installation. This text is about how the
1251 text processing of this manual is handled in the project.
</p
>
1253 <p
>One goal of the project is to provide information in the native
1254 language of its users, and for this we need to handle translations.
1255 But we also want to make sure each language contain the same
1256 information, so for this we need a good way to keep the translations
1257 in sync. And we want it to be easy for our users to improve the
1258 documentation, avoiding the need to learn special formats or tools to
1259 contribute, and the obvious way to do this is to make it possible to
1260 edit the documentation using a web browser. We also want it to be
1261 easy for translators to keep the translation up to date, and give them
1262 help in figuring out what need to be translated. Here is the list of
1263 tools and the process we have found trying to reach all these
1266 <p
>We maintain the authoritative source of our manual in the
1267 <a href=
"https://wiki.debian.org/DebianEdu/Documentation/Wheezy/
">Debian
1268 wiki
</a
>, as several wiki pages written in English. It consist of one
1269 front page with references to the different chapters, several pages
1270 for each chapter, and finally one
"collection page
" gluing all the
1271 chapters together into one large web page (aka
1272 <a href=
"https://wiki.debian.org/DebianEdu/Documentation/Wheezy/AllInOne
">the
1273 AllInOne page
</a
>). The AllInOne page is the one used for further
1274 processing and translations. Thanks to the fact that the
1275 <a href=
"http://moinmo.in/
">MoinMoin
</a
> installation on
1276 wiki.debian.org support exporting pages in
1277 <a href=
"http://www.docbook.org/
">the Docbook format
</a
>, we can fetch
1278 the list of pages to export using the raw version of the AllInOne
1279 page, loop over each of them to generate a Docbook XML version of the
1280 manual. This process also download images and transform image
1281 references to use the locally downloaded images. The generated
1282 Docbook XML files are slightly broken, so some post-processing is done
1283 using the
<tt
>documentation/scripts/get_manual
</tt
> program, and the
1284 result is a nice Docbook XML file (debian-edu-wheezy-manual.xml) and
1285 a handfull of images. The XML file can now be used to generate PDF, HTML
1286 and epub versions of the English manual. This is the basic step of
1287 our process, making PDF (using dblatex), HTML (using xsltproc) and
1288 epub (using dbtoepub) version from Docbook XML, and the resulting files
1289 are placed in the debian-edu-doc-en binary package.
</p
>
1291 <p
>But English documentation is not enough for us. We want translated
1292 documentation too, and we want to make it easy for translators to
1293 track the English original. For this we use the
1294 <a href=
"http://packages.qa.debian.org/p/poxml.html
">poxml
</a
> package,
1295 which allow us to transform the English Docbook XML file into a
1296 translation file (a .pot file), usable with the normal gettext based
1297 translation tools used by those translating free software. The pot
1298 file is used to create and maintain translation files (several .po
1299 files), which the translations update with the native language
1300 translations of all titles, paragraphs and blocks of text in the
1301 original. The next step is combining the original English Docbook XML
1302 and the translation file (say debian-edu-wheezy-manual.nb.po), to
1303 create a translated Docbook XML file (in this case
1304 debian-edu-wheezy-manual.nb.xml). This translated (or partly
1305 translated, if the translation is not complete) Docbook XML file can
1306 then be used like the original to create a PDF, HTML and epub version
1307 of the documentation.
</p
>
1309 <p
>The translators use different tools to edit the .po files. We
1311 <a href=
"http://www.kde.org/applications/development/lokalize/
">lokalize
</a
>,
1312 while some use emacs and vi, others can use web based editors like

1354 keep gaining new users. Some weeks ago, a person showed up on IRC,
1355 <a href=
"irc://irc.debian.org/#debian-edu
">#debian-edu
</a
>, with a
1356 wish to contribute, and I managed to get a interview with this great
1357 contributor Roger Marsal to learn more about his background.
</p
>
1359 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
1361 <p
>My name is Roger Marsal, I
'm
27 years old (
1986 generation) and I
1362 live in Barcelona, Spain. I
've got a strong business background and I
1363 work as a patrimony manager and as a real estate agent. Additionally,
1364 I
've co-founded a British based tech company that is nowadays on the
1365 last development phase of a new social networking concept.
</p
>
1367 <p
>I
'm a Linux enthusiast that started its journey with Ubuntu four years
1368 ago and have recently switched to Debian seeking rock solid stability
1369 and as a necessary step to gain expertise.
</p
>
1371 <p
>In a nutshell, I spend my days working and learning as much as I
1372 can to face both my job, entrepreneur project and feed my Linux
1375 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
1376 project?
</strong
></p
>
1378 <p
>I discovered the
<a href=
"http://www.ltsp.org/
">LTSP
</a
> advantages
1379 with
"Ubuntu
12.04 alternate install
" and after a year of use I
1380 started looking for an alternative. Even though I highly value and
1381 respect the Ubuntu project, I thought it was necessary for me to
1382 change to a more robust and stable alternative. As far as I was using
1383 Debian on my personal laptop I thought it would be fine to install
1384 Debian and configure an LTSP server myself. Surprised, I discovered
1385 that the Debian project also supported a kind of Edubuntu equivalent,
1386 and after having some pain I obtained a Debian Edu network up and
1387 running. I just loved it.
</p
>
1389 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
1390 Edu?
</strong
></p
>
1392 <p
>I found a main advantage in that, once you know
"the tips and
1393 tricks
", a new installation just works out of the box. It
's the most
1394 complete alternative I
've found to create an LTSP network. All the
1395 other distributions seems to be made of plastic, Debian Edu seems to
1396 be made of steel.
</p
>
1398 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
1399 Edu?
</strong
></p
>
1401 <p
>I found two main disadvantages.
</p
>
1403 <p
>I
'm not an expert but I
've got notions and I had to spent a considerable
1404 amount of time trying to bring up a standard network topology. I
'm quite
1405 stubborn and I just worked until I did but I
'm sure many people with few
1406 resources (not big schools, but academies for example) would have switched
1407 or dropped.
</p
>
1409 <p
>It
's amazing how such a complex system like Debian Edu has achieved
1410 this out-of-the-box state. Even though tweaking without breaking gets
1411 more difficult, as more factors have to be considered. This can
1412 discourage many people too.
</p
>
1414 <p
><strong
>Which free software do you use daily?
</strong
></p
>
1416 <p
>I use Debian, Firefox, Okular, Inkscape, LibreOffice and
1417 Virtualbox.
</p
>
1420 <p
><strong
>Which strategy do you believe is the right one to use to
1421 get schools to use free software?
</strong
></p
>
1423 <p
>I don
't think there is a need for a particular strategy. The free
1424 attribute in both
"freedom
" and
"no price
" meanings is what will
1425 really bring free software to schools. In my experience I can think of
1426 the
<a href=
"http://www.r-project.org/
">"R
" statistical language
</a
>; a
1427 few years a ago was an extremely nerd tool for university people.
1428 Today it
's being increasingly used to teach statistics at many
1429 different level of studies. I believe free and open software will
1430 increasingly gain popularity, but I
'm sure schools will be one of the
1431 first scenarios where this will happen.

1440 <description><p
>On larger sites, it is useful to use a dedicated storage server for
1441 storing user home directories and data. The design for handling this
1442 in
<a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>, is
1443 to update the automount rules in LDAP and let the automount daemon on
1444 the clients take care of the rest. I was reminded about the need to
1445 document this better when one of the customers of
1446 <a href=
"http://www.slxdrift.no/
">Skolelinux Drift AS
</a
>, where I am
1447 on the board of directors, asked about how to do this. The steps to
1448 get this working are the following:
</p
>
1452 <li
>Add new storage server in DNS. I use nas-server.intern as the
1453 example host here.
</li
>
1455 <li
>Add automoun LDAP information about this server in LDAP, to allow
1456 all clients to automatically mount it on reqeust.
</li
>
1458 <li
>Add the relevant entries in tjener.intern:/etc/fstab, because
1459 tjener.intern do not use automount to avoid mounting loops.
</li
>
1461 </ol
></p
>
1463 <p
>DNS entries are added in GOsa², and not described here. Follow the
1464 <a href=
"https://wiki.debian.org/DebianEdu/Documentation/Wheezy/GettingStarted
">instructions
1465 in the manual
</a
> (Machine Management with GOsa² in section Getting
1468 <p
>Ensure that the NFS export points on the server are exported to the
1469 relevant subnets or machines:
</p
>
1471 <p
><blockquote
><pre
>
1472 root@tjener:~# showmount -e nas-server
1473 Export list for nas-server:
1476 </pre
></blockquote
></p
>
1478 <p
>Here everything on the backbone network is granted access to the
1479 /storage export. With NFSv3 it is slightly better to limit it to
1480 netgroup membership or single IP addresses to have some limits on the
1481 NFS access.
</p
>
1483 <p
>The next step is to update LDAP. This can not be done using GOsa²,
1484 because it lack a module for automount. Instead, use ldapvi and add
1485 the required LDAP objects using an editor.
</p
>
1487 <p
><blockquote

>
1488 ldapvi --ldap-conf -ZD
'(cn=admin)
' -b ou=automount,dc=skole,dc=skolelinux,dc=no
1489 </pre
></blockquote
></p
>
1491 <p
>When the editor show up, add the following LDAP objects at the
1492 bottom of the document. The
"/
&" part in the last LDAP object is a
1493 wild card matching everything the nas-server exports, removing the
1494 need to list individual mount points in LDAP.
</p
>
1496 <p
><blockquote
><pre
>
1497 add cn=nas-server,ou=auto.skole,ou=automount,dc=skole,dc=skolelinux,dc=no

&
1511 </pre

></p
>
1513 <p
>The last step to remember is to mount the relevant mount points in
1514 tjener.intern by adding them to /etc/fstab, creating the mount
1515 directories using mkdir and running
"mount -a
" to mount them.
</p
>
1517 <p
>When this is done, your users should be able to access the files on
1518 the storage server directly by just visiting the
1519 /tjener/nas-server/storage/ directory using any application on any
1520 workstation, LTSP client or LTSP server.

1531 was able to get an interview with a newcomer in the project who showed
1532 up on the IRC channel a few weeks ago to let us know about his
1533 successful installation of Debian Edu Wheezy in his School. Say hello

1539 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p

1541 <p
>I am a
23 year-old student from Germany who has spent half of his
1542 life with open source. In
"real life
", I am, as already mentioned, a
1543 student in the fields of Computer Science, Electrical Engineering,
1544 Information Technologies and Anglistics. Due to my (only partially
1545 voluntary) huge engagement in the open source world, these things are
1546 a bit vacant right now however.
</p
>
1548 <p
>I also have been working as a project teacher at a Gymasnium
1549 (public school) for various years now. I took up that work some time
1550 around
2005 when still attending that school myself and have continued
1551 it until today. I also had been running the (kind of very advanced)
1552 network of that school together with a team of very interested and
1553 talented students in the age of
11 to
15 years, who took the chance to
1554 learn a lot about open source and networking before I left the school
1555 to help building another school
's informational education concept from
1558 <p
>That said, one might see me as a kind of
"glue
" between school kids
1559 and the elderly of teachers as well as between the open source
1560 ecosystem and the (even more complex) educational ecosystem.
</p
>
1562 <p
>When I am not busy with open source or education, I like Geocaching
1563 and cycling.
</p
>
1565 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
1566 project?
</strong
></p
>
1568 <p
>I think that happened some time around
2009 when I first attended
1569 <a href=
"http://www.froscon.org
">FrOSCon
</a
> and visited the project
1570 booth. I think I wasn
't too interested back then because I used to
1571 have an attitude of disliking software that does too much stuff on its
1572 own. Maybe I was too inexperienced to realise the upsides of an
1573 "out-of-the-box
" solution ;).
</p
>
1575 <p
>The first time I actively talked to Skolelinux people was at
1576 <a href=
"http://www.openrheinruhr.de
">OpenRheinRuhr
</a
> 2011 when the
1577 BiscuIT project, a home-grewn software used by my school for various
1578 really cool things from timetables and class contact lists to lunch
1579 ordering, student ID card printing and project elections first got to
1580 a stage where it could have been published. I asked the Skolelinux
1581 guys running the booth if the project were interested in it and gave a
1582 small demonstration, but there wasn
't any real feedback and the guys
1583 seemed rather uninterested.
</p
>
1585 <p
>After I left the school where I developed the software, it got
1586 mostly lost, but I am now reimplementing it for my new school. I have
1587 reusability and compatibility in mind, and I hop there will be a new
1588 basis for contributing it to the Skolelinux project ;)!
</p
>
1590 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
1591 Edu?
</strong
></p
>
1593 <p
>The most important advantage seems to be that it
"just
1594 works
". After overcoming some minor (but still very annoying) glitches
1595 in the installer, I got a fully functional, working school network,
1596 without the month-long hassle I experienced when setting all that up
1597 from scratch in earlier years. And above that, it rocked - I didn
't
1598 have any real hardware at hand, because the school was just founded
1599 and has no money whatsoever, so I installed a combined server (main
1600 server, terminal services and workstation) in a VM on my personal
1601 notebook, bridging the LTSP network interface to the ethernet port,
1602 and then PXE-booted the Windows notebooks that were lying around from
1603 it. I could use
8 clients without any performance issues, by using a
1604 tiny little VM on a tiny little notebook. I think that
's enough to say
1605 that it rocks!
</p
>
1607 <p
>Secondly, there are marketing reasons. Life
's bad, and so no
1608 politician will ever permit a setup described as
"Debian, an universal
1609 operating system, with some really cool educational tools
" while they
1610 will be jsut fine with
"Skolelinux, a single-purpose solution for your
1611 school network
", even if both turn out to be the very same thing (yes,
1612 this is unfair towards the Skolelinux project, and must not be taken
1613 too seriously - you get the idea, anyway).
</p
>
1615 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
1616 Edu?
</strong
></p
>
1618 <p
>I have not been involved with Skolelinux long enough to really
1619 answer this question in a fair way. Thus, please allow me to put it in
1620 other words:
"What do you expect from Skolelinux to keep liking it?
" I
1621 can list a few points about that:
</p
>
1625 <li
>always strive to get all things integrated into Debian upstream
1626 <li
>be open to discussion about changes and the like, even with newcomers
1627 <li
>be helpful at being helpful ;)
1631 <p
>I
'm really sorry I cannot say much more about that :(!
</p
>
1633 <p
><strong
>Which free software do you use daily?
</strong
></p
>
1635 <p
>First of all, all software I use is free and open. I have abandoned
1636 all non-free software (except for firmware on my darned phone) this
1639 <p
>I run Debian GNU/Linux on all PC systems I use. On that, I mostly
1640 run text tools. I use
1641 <a href=
"https://www.mirbsd.org/mksh.htm
">mksh
</a
> as shell,
1642 <a href=
"https://www.mirbsd.org/jupp.htm
">jupp
</a
> as very advanced
1643 text editor (I even got the developer to help me write a script/macro
1644 based full-featured student management software with the two),
1645 <a href=
"http://mcabber.com/
">mcabber
</a
> for XMPP and
1646 <a href=
"http://www.irssi.org/
">irssi
</a
> for IRC. For that overly
1647 coloured world called the WWW, I use
1648 <a href=
"https://www.mozilla.org/en-US/firefox/new/
">Iceweasel
1649 (Firefox)
</a
>. Oh, and
<a href=
"http://www.mutt.org/
">mutt
</a
> for
1652 <p
>However, while I am personally aware of the fact that text tools
1653 are more efficient and powerful than anything else, I also use (or at
1654 least operate) some tools that are suitable to bring open source to
1655 kids. One of these things is
<a href=
"http://jappix.org/
">Jappix
</a
>,
1656 which I already introduced to some kids even before they got aware of
1657 Facebook, making them see for themselves that they do not need
1658 Facebook now ;).
</p
>
1660 <p
><strong
>Which strategy do you believe is the right one to use to
1661 get schools to use free software?
</strong
></p
>
1663 <p
>Well, that
's a two-sided thing. One side is what I believe, and one
1664 side is what I have experienced.
</p
>
1666 <p
>I believe that the right strategy is showing them the benefits. But
1667 that won
't work out as long as the acceptance of free alternatives
1668 grows globally. What I mean is that if all the kids are almost forced
1669 to use Windows, Facebook, Skype, you name it at home, they will not
1670 see why they would want to use alternatives at school. I have seen
1671 students take seat in front of a fully-functional, modern Debian
1672 desktop that could do anything their Windows at home could do, and
1673 they jsut refused to use it because
"Linux sucks
". It is something
1674 that makes the council of our city spend around
600000 € to buy
1675 software - not including hardware, mind you - for operating school
1676 networks, and for installing a system that, as has been proved, does
1677 not work. For those of you readers who are good at maths, have you
1678 already found out how many lives could have been saved with that money
1679 if we had instead used it to bring education to parts of the world
1680 that need it? I have, and found it to be nothing less dramatic than
1681 plain criminal.
</p
>
1683 <p
>That said, the only feasible way appears to be the bottom up
1684 method. We have to bring free software to kids and parents. I have
1685 founded an association named
1686 <a href=
"https://www.teckids.org
">Teckids
</a
> here in Germany that does
1687 just that. We organise several events for kids and adolescents in the
1688 area of free and open source software, for example the
1689 <a href=
"http://kids.froscon.org
">FrogLabs
</a
>, which share staff with
1690 Teckids and are the youth programme of
1691 <a href=
"http://www.froscon.org
">the Free and Open Source Software
1692 Conference (FrOSCon)
</a
>. We do a lot more than most other conferences
1693 - this year, we first offered the FrogLabs as a holiday camp for kids
1694 aged
10 to
16. It was a huge success, with approx.
30 kids taking part
1695 and learning with and about free software through a whole weekend. All
1696 of us had a lot of fun, and the results were really exciting.
</p
>
1698 <p
>Apart from that, we are preparing a campaign that is supposed to bring
1699 the message of free alternatives to stuff kids use every day to them and
1700 their parents, e.g. the use of Jabber / Jappix instead of Facebook and
1701 Skype. To make that possible, we are planning to get together a team of
1702 clever kids who understand very well what their peers need and can bring
1703 it across to them. So we will have a peer-driven network of adolescents
1704 who teach each other and collect feedback from the community of minors.
1705 We then take that feedback and our own experience to work closely with
1706 open source projects, such as Skolelinux or Jappix, at improving their
1707 software in a way that makes it more and more attractive for the target
1708 group. At least I hope that we will have good cooperation with
1709 Skolelinux in the future ;)!
</p
>
1711 <p
>So in conclusion, what I believe is that, if it weren
't for the world
1712 being so bad, it should be very clear to the political decision makers
1713 that the only way to go nowadays is free software for various reasons,
1714 but I have learnt that the only way that seems to work is bottom up.
</p
>
1718 > * Who should be interviewed with this questions in the future?
1720 That
's probably the hardest question of them all, as I do not know the
1721 community. However, I would be willing to do the following:
1723 <li
>Run an interview with a German headteacher who is very open to
1724 free software, and also prefers it, but cannot really use it because
1725 of the decision makers above;

1741 but the
<a href=
"http://www.skolelinux.org/
">Debian Edu /
1742 Skolelinux
</a

1743 had a new school administrator show up on
1744 <a href=
"irc://irc.debian.org/#debian-edu
">#debian-edu
</a
> to share
1745 his success story with installing Debian Edu at their school. This
1746 time I have been able to get some helpful comments from the creator of
1747 Knoppix, Klaus Knopper, who was involved in a Skolelinux project in
1748 Germany a few years ago.

1750 <p

1752 <p
>I am Klaus Knopper. I have a master degree in electrical
1753 engineering, and is currently professor in information management at
1754 the university of applied sciences Kaiserslautern / Germany and
1755 freelance Open Source software developer and consultant.
</p
>
1757 <p
>All of this is pretty much of the work I spend my days with. Apart
1758 from teaching, I
'm also conducting some more or less experimental
1759 projects like the
<a href=

1764 (Linux-based network boot console, a fast remote install and repair

</p

>How did you get in contact with the Skolelinux / Debian Edu
1768 project?
</strong
></p
>
1770 <p
>The credit for this have to go to Kurt Gramlich, who is the German
1771 coordinator for Skolelinux. We were looking for an all-in-one open
1772 source community-supported distribution for schools, and Kurt
1773 introduced us to Skolelinux for this purpose.
</p

1775 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
1776 Edu?
</strong
></p
>
1779 <li
>Quick installation,
</li
>
1780 <li
>works (almost) out of the box,
</li
>
1781 <li
>contains many useful software packages for teaching and learning,
</li
>
1782 <li
>is a purely community-based distro and not controlled by a
1783 single company,
</li
>
1784 <li
>has a large number of supporters and teachers who share their
1785 experience and problem solutions.
</li
>
1788 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
1789 Edu?
</strong
></p
>
1792 <li
>Skolelinux is - as we had to learn - not easily upgradable to
1793 the next version. Opposed to its genuine Debian base, upgrading to
1794 a new version means a full new installation from scratch to get it
1795 working again reliably.
1797 <li
>Skolelinux is based on Debian/stable, and therefore always a
1798 little outdated in terms of program versions compared to Edubuntu or
1799 similar educational Linux distros, which rather use Debian/testing
1802 <li
>Skolelinux has some very self-opinionated and stubborn default
1803 configuration which in my opinion adds unnecessary complexity and is
1804 not always suitable for a schools needs, the preset network
1805 configuration is actually a core definition feature of Skolelinux
1806 and not easy to change, so schools sometimes have to change their
1807 network configuration to make it
"Skolelinux-compatible
".
1809 <li
>Some proposed extensions, which were made available as
1810 contribution, like secure examination mode and lecture material
1811 distribution and collection, were not accepted into the mainline
1812 Skolelinux development and are now not easy to maintain in the
1813 future because of Skolelinux somewhat undeterministic update
1816 <li
>Skolelinux has only a very tiny number of base developers
1817 compared to Debian.
</li
>
1821 <p
>For these reasons and experience from our project, I would now
1822 rather consider using plain Debian for schools next time, until
1823 Skolelinux is more closely integrated into Debian and becomes
1824 upgradeable without reinstallation.
</p
>
1826 <p
><strong
>Which free software do you use daily?
</strong
></p
>
1828 <p
>GNU/Linux with LXDE desktop, bash for interactive dialog and
1829 programming, texlive for documentation and correspondence,
1830 occasionally LibreOffice for document format conversion. Various
1831 programming languages for teaching.
</p
>
1833 <p
><strong
>Which strategy do you believe is the right one to use to
1834 get schools to use free software?
</strong
></p
>
1836 <p
>Strong arguments are
</p
>
1840 <li
>Knowledge is free, and so should be methods and tools for
1841 teaching and learning.
</li
>
1843 <li
>Students can learn with and use the same software at school, at
1844 home, and at their working place without running into license or
1845 conversion problems.
</li
>
1847 <li
>Closed source or proprietary software hides knowledge rather
1848 than exposing it, and proprietary software vendors try to bind
1849 customers to certain products. But teachers need to teach
1850 science, not products.
</li
>
1852 <li
>If you have everything you for daily work as open source, what
1853 would you need proprietary software for?

>About Debian Edu and Skolelinux
</p
>
1985 <p
>Debian Edu, also known as Skolelinux, is a Linux distribution based
1986 on Debian providing an out-of-the box environment of a completely
1987 configured school network. Immediately after installation a school
1988 server running all services needed for a school network is set up just
1989 waiting for users and machines being added via GOsa², a comfortable
1990 Web-UI. A netbooting environment is prepared using PXE, so after
1991 initial installation of the main server from CD or USB stick all other
1992 machines can be installed via the network. The provided school server
1993 provides LDAP database and Kerberos authentication service,
1994 centralized home directories, DHCP server, web proxy and many other
1995 services. The desktop contains more than
60 educational software
1996 packages and more are available from the Debian archive, and schools
1997 can choose between KDE, Gnome, LXDE and Xfce desktop environment.
</p
>
1999 <p
>This is the seventh test release based on Debian Wheezy. Basically
2000 this is an updated and slightly improved version compared to the
2001 Squeeze release.
</p
>
2003 <p
>Notes for upgrades from Alpha Prereleases
</p
>
2005 <p
>Alpha based installations should reinstall or downgrade the
2006 versions of gosa and libpam-mklocaluser to the ones used in this beta
2007 release. Both alpha and beta0 based installations should reinstall or
2008 deal with gosa.conf manually; there are two options: (
1) Keep
2009 gosa.conf and edit this file as outlined on the mailing list. (
2)
2010 Accept the new version of gosa.conf and replace both contained admin
2011 password placeholders with the password hashes found in the old one
2012 (backup copy!). In both cases all users need to change their password
2013 to make sure a password is set for CIFS access to their home
2014 directory.

><a href=
"http://www.skolelinux.org/
">Debian Edu, also known as
2173 Skolelinux
</a
>, is a Linux distribution based on Debian providing an
2174 out-of-the box environment of a completely configured school
2175 network. Immediately after installation a school server running all
2176 services needed for a school network is set up just waiting for users
2177 and machines being added via GOsa², a comfortable Web-UI. A netbooting
2178 environment is prepared using PXE, so after initial installation of
2179 the main server from CD, DVD or USB stick all other machines can be
2180 installed via the network. The provided school server provides LDAP
2181 database and Kerberos authentication service, centralized home
2182 directories, DHCP server, web proxy and many other services. The
2184 <a href=
"http://people.skolelinux.org/pere/blog/Educational_applications_included_in_Debian_Edu___Skolelinux__the_screenshot_collection____.html
">more
2185 than
60 educational software packages
</a
> and more are available from
2186 the Debian archive, and schools can choose between KDE, Gnome, LXDE
2187 and Xfce desktop environment.
</p
>
2189 <p
>This is the fifth test release based on Debian Wheezy. Basically
2190 this is an updated and slightly improved version compared to the
2191 Squeeze release.
</p
>
2193 <p
>ALERT: Alpha based installations should reinstall or downgrade the
2194 versions of gosa and libpam-mklocaluser to the ones used in this beta
2197 <p
><strong
>Software updates
</strong
></p
>
2201 <li
>Switched roaming workstation profiles from wicd to network-manager
2202 for network configuration, as wicd didn
't work any more.
</li
>
2203 <li
>Changed version numbers of patched gosa and libpam-mklocaluser
2204 packages to make sure our locally patched versions will be replaced
2205 by the official packages when they are released from Debian. Those
2206 installing alpha version need to reinstall or manually downgrade gosa
2207 and libpam-mklocaluser.
</li
>
2208 <li
>Added bluetooth tools to the default desktop (bluedevil, blueman).
</li
>
2209 <li
>Added tools for sharing the desktop on KDE (krdc, krfb).
</li
>
2210 <li
>Added valgrind to the default installation for easier debugging of
2211 crash bugs.
</li
>
2215 <p
><strong
>Other changes
</strong
></p
>
2219 <li
>Fixed artwork package to work with gnome, no longer break
2220 desktop=gnome installations.
</li
>
2221 <li
>Adjusted installer to now work when forced to use a proxy with the
2222 netinst CD.
</li
>
2223 <li
>Fixed code detecting and setting/loading hardware specific
2224 setup/firmware to work more robust out of the box.
</li
>
2225 <li
>Adjusted Kerberos setup to detect realm and server settings at
2226 install time instead of dynamically at run time. This avoid a crash
2227 with krb5-auth-dialog on diskless workstations without a DNS name.
</li
>
2228 <li
>Worked around misfeature in network-manager not calling the dhclient
2229 exit hooks, causing automatic proxy configuration and automatic host
2230 name setting at run time to work again.
</li
>
2231 <li
>Fixed feature setting the default Iceweasel start page from URL
2232 fetched from LDAP, to allow schools to set the global default by
2233 updating the dc=skole,dc=skolelinux,dc=no LDAP object.
</li
>
2234 <li
>Changed default host name on all networked machines to be unique
2235 (generated from MAC or reverse DNS) after boot.
</li
>
2236 <li
>Adjusted partition sizes to make sure they are big enough.
</li
>
2240 <p
><strong
>Known issues
</strong
></p
>
2244 <li
>Grub is missing the new artwork.
</li
>
2245 <li
>KDE fail to understand the wpad.dat file provided, causing it to
2246 not use the http proxy as it should.
</li
>
2247 <li
>Chromium also fail to use the proxy.

2348 <li
>Dropped ispell dictionaries from our default installation.
</li
>
2349 <li
>Dropped menu-xdg from the KDE desktop option, to drop the Debian
2350 submenu. It was not included with Gnome, LXDE or Xfce, so this
2351 brings KDE in line with the others.
</li
>
2352 <li
>Dropped xdrawchem, xjig and xsok from our default installation as
2353 they don
't have a desktop menu entry and thus won
't show up in the
2354 menu now that menu-xdg was removed.
</li
>
2355 <li
>Removed the killer system to kill left behind processes on
2356 multi-user machines, as it was no longer able to understand when a
2357 X display was in use and killed the processes of the active users
2359 <li
>Dropped the golearn (from goplay) package as the debtags in wheezy
2360 are too few to make the package useful.

2368 <li
>Switched to using http.debian.net as APT source by default.
</li

2371 d-i is doing it.
</li
>
2372 <li
>Made sure root and user passwords were not left behind in the
2373 debconf database after installation on Main Server installations.
</li
>
2374 <li
>Made Roaming Workstation dynamic setup more robust and added draft
2375 script setup-ad-client to hook a Roaming Workstation up to a
2376 Active Directory server instead of a Debian Edu Main Server.
</li
>
2377 <li
>Update system to install needed firmware packages during

2379 <li

2381 and keymap settings to PXE installation clients.

2424 <description><p
>In the
<a href=
"http://www.skolelinux.org/
">Debian Edu /
2425 Skolelinux
</a
> project, we include a post-installation test suite,
2426 which check that services are running, working, and return the
2427 expected results. It runs automatically just after the first boot on
2428 test installations (using test ISOs), but not on production
2429 installations (using non-test ISOs). It test that the LDAP service is
2430 operating, Kerberos is responding, DNS is replying, file systems are
2431 online resizable, etc, etc. And it check that the PXE service is
2432 configured, which is the topic of this post.
</p
>
2434 <p
>The last week I
've fixed the DVD and USB stick ISOs for our Debian
2435 Edu Wheezy release. These ISOs are supposed to be able to install a
2436 complete system without any Internet connection, but for that to
2437 happen all the needed packages need to be on them. Thanks to our test
2438 suite, I discovered that we had forgotten to adjust our PXE setup to
2439 cope with the new names and paths used by the netboot d-i packages.
2440 When Internet connectivity was available, the installer fall back to
2441 using wget to fetch d-i boot images, but when offline it require
2442 working packages to get it working. And the packages changed name
2443 from debian-installer-
6.0-netboot-$arch to
2444 debian-installer-
7.0-netboot-$arch, we no longer pulled in the
2445 packages during installation. Without our test suite, I suspect we
2446 would never have discovered this before release. Now it is fixed
2447 right after we got the ISOs operational.
</p
>
2449 <p
>Another by-product of the test suite is that we can ask system
2450 administrators with problems getting Debian Edu to work, to run the
2451 test suite using
<tt
>/usr/sbin/debian-edu-test-install
</tt
> and see if
2452 any errors are detected. This usually pinpoint the subsystem causing
2453 the problem.

2484 country. A few days later, we put together the infrastructure for such
2485 community and even gathered a nice Debian-ish crowd. Since then, I
2486 began my quest as a free software hacker and activist and I am
2487 constantly trying to cover as much ground as possible on that
2490 <p
>A few years ago I founded a small web development company, which
2491 provided me the flexible schedule I needed so much for my
2492 activities. For the last
13 months, I have been the Technical Director
2493 of
<a href=
"http://ceata.org/
">Fundația Ceata
</a
>, which is a free
2494 software activist organisation endorsed by the FSF and the FSFE, and
2495 the only one we have in our country.

2497 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
2498 project?
</strong
></p
>
2500 <p
>The idea of participating in the Debian Edu project was a surprise
2501 even to me, since I never used it before I began getting involved in
2502 it. This year I had a great opportunity to deliver a talk on
2503 educational software, and I knew immediately where to look. It was a
2504 love at first sight, since I was previously involved with some of the
2505 technologies the project incorporates, and I rapidly found a lot of
2506 ways to contribute.
</p
>
2508 <p
>My first contributions consisted in translating the installer and
2509 configuration dialogs, then I found some bugs to squash (I still
2510 haven
't fixed them yet though), and I even got my eyes on some other
2511 areas where I can prove myself helpful. Since the appetite for free
2512 software in my country is pretty low, I
'll be happy to be the first
2513 one around here advocating for the project
's adoption in educational
2514 environments, and maybe even get my hands dirty in creating a flavour
2515 for our own needs. I am not used to make very advanced plannings, so
2516 from now on, time will tell what I
'll be doing next, but I think I
2517 have a pretty consistent starting point.
</p

2519 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
2520 Edu?
</strong
></p

2522 <p
>Not a long time ago, I was in the position of configuring and
2523 maintaining a LDAP server on some Debian derivative, and I must say it
2524 took me a while. A long time ago, I was maintaining a bigger
2525 Samba-powered infrastructure, and I must say I spent quite a lot of
2526 time on it. I have similar stories about many of the services included
2527 with Skolelinux, and the main advantage I see about it is the
2528 out-of-the box availability of them, making it quite competitive when
2529 it comes to managing a school
's network, for example.
</p
>
2531 <p
>Of course, there is more to say about Skolelinux than the
2532 availability of the software included, its flexibility in various
2533 scenarios is something I can
't wait to experiment
"into the wild
" (I
2534 only played with virtual machines so far). And I am sure there is a
2535 lot more I haven
't discovered yet about it, being so new within the

><strong
>What do you see as the disadvantages of Skolelinux / Debian
2539 Edu?
</strong
></p
>
2541 <p
>As usual, when it comes to Debian Blends, I see as the biggest
2542 disadvantage the lack of a numerous team dedicated to the
2543 project. Every day I see the same names in the changelogs, and I have
2544 a constantly fear of the bus factor in this story. I
'd like to see
2545 Debian Edu advertised more as an entry point into the Debian
2546 ecosystem, especially amongst newcomers and students. IMHO there are a
2547 lot low-hanging fruits in terms of bug squashing, and enough
2548 opportunities to get the feeling of the Debian Project
's dynamics. Not
2549 to mention it
's a very fun blend to work on!
</p
>
2551 <p
>Derived from the previous statement, is the delay in catching up
2552 with the main Debian release and documentation. This is common though
2553 to all blends and derivatives, but it
's an issue we can all work
2556 <p
><strong
>Which free software do you use daily?
</strong
></p
>
2558 <p
>I can hardly imagine myself spending a day without Vim, since my
2559 daily routine covers writing code and hacking configuration files. I
2560 am a fan of the Awesome window manager (but I also like the
2561 Enlightenment project a lot!),
2562 <a href=
"http://www.claws-mail.org/

2563 use and very configurable behaviour. Recently I fell in love with

2565 get through the night without headaches. Of course, there is much more
2566 stuff in this bag, but I
'll need a blog on my own for doing this!

2571 <p
>Well, on this field, I cannot do much more than experiment right
2572 now. So, being far from having a recipe for success, I can only assume
2577 <li
>schools would like to get rid of proprietary software
</li
>
2579 <li
>students will love the openness of the system, and will want to
2580 experiment with it - maybe we need to harvest the native curiosity
2581 of teenagers more?
</li

2583 <li
>there is no
"right one
" when it comes to strategies, but it would
2584 be useful to have some success stories published somewhere, so
2585 other can get some inspiration from them (I know I
'd promote
2588 <li
>more active promotion - talks, conferences, even small school
2589 lectures can do magical things if they encounter at least one
2590 person interested. Who knows who that person might be? ;-)
</li

2594 <p
>I also see some problems in getting Skolelinux into schools; for
2595 example, in our country we have a great deal of corruption issues, so
2596 it might be hard(er) to fight against proprietary solutions. Also,
2597 people who relied on commercial software for all their lives, would be
2598 very hard to convert against their will.

>There is a certain cross-over between the
2608 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
2609 project
</a
> and
<a href=
"http://www.edubuntu.org/
">the Edubuntu
2610 project
</a
>, and for example the LTSP packages in Debian are a joint
2611 effort between the projects. One person with a foot in both camps is
2612 Jonathan Carter, which I am now happy to present to you.
</p
>
2614 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
2616 <p
>I
'm a South-African free software geek who lives in Cape Town. My
2617 days vary quite a bit since I
'm involved in too many things. As I
'm
2618 getting older I
'm learning how to focus a bit more :)
</p
>
2620 <p
>I
'm also an Edubuntu contributor and I love when there are
2621 opportunities for the Edubuntu and Debian Edu projects to benefit from
2622 each other.
</p
>
2624 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
2625 project?
</strong
></p
>
2627 <p
>I
've been somewhat familiar with the project before, but I think my
2628 first direct exposure to the project was when I met Petter
2629 [Reinholdtsen] and Knut [Yrvin] at the Edubuntu summit in
2005 in
2630 London. They provided great feedback that helped the bootstrapping of
2631 Edubuntu. Back then Edubuntu (and even Ubuntu) was still very new and
2632 it was great getting input from people who have been around longer. I
2633 was also still very excitable and said yes to everything and to this
2634 day I have a big todo list backlog that I
'm catching up with. I think
2635 over the years the relationship between Edubuntu and Debian-Edu has
2636 been gradually improving, although I think there
's a lot that we could
2637 still improve on in terms of working together on packages. I
'm sure
2638 we
'll get there one day.
</p
>
2640 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
2641 Edu?
</strong
></p
>
2643 <p
>Debian itself already has so many advantages. I could go on about
2644 it for pages, but in essence I love that it
's a very honest project
2645 that puts its users first with no hidden agendas and also produces
2646 very high quality work.
</p
>
2648 <p
>I think the advantage of Debian Edu is that it makes many common
2649 set-up tasks simpler so that administrators can get up and running
2650 with a lot less effort and frustration. At the same time I think it
2651 helps to standardise installations in schools so that it
's easier for
2652 community members and commercial suppliers to support.
</p
>
2654 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
2655 Edu?
</strong
></p
>
2657 <p
>I had to re-type this one a few times because I
'm trying to
2658 separate
"disadvantages
" from
"areas that need improvement
" (which is
2659 what I originally rambled on about)
</p
>
2661 <p
>The biggest disadvantage I can think of is lack of manpower. The
2662 project could do so much more if there were more good contributors. I
2663 think some of the problems are external too. Free software and free
2664 content in education is a no-brainer but it takes some time to catch
2665 on. When you
've been working with the same proprietary eco-system for
2666 years and have gotten used to it, it can be hard to adjust to some
2667 concepts in the free software world. It would be nice if there were
2668 more Debian Edu consultants across the world. I
'd love to be one
2669 myself but I
'm already so over-committed that it
's just not possible
2670 currently.
</p
>
2672 <p
>I think the best short-term solution to that large-scale problem is
2673 for schools to be pro-active and share their experiences and grow
2674 their skills in-house. I
'm often saddened to see how much money
2675 educational institutions spend on
3rd party solutions that they don
't
2676 have access to after the service has ended and they could
've gotten so
2677 much more value otherwise by being more self-sustainable and
2678 autonomous.
</p
>
2680 <p
><strong
>Which free software do you use daily?
</strong
></p
>
2682 <p
>My main laptop dual-boots between Debian and Windows
7. I was
2683 Windows free for years but started dual-booting again last year for
2684 some games which help me focus and relax (Starcraft II in
2685 particular). Gaming support on Linux is improving in leaps and bounds
2686 so I suppose I
'll soon be able to regain that disk space :)
</p
>
2688 <p
>Besides that I rely on Icedove, Chromium, Terminator, Byobu, irssi,
2689 git, Tomboy, KVM, VLC and LibreOffice. Recently I
've been torn on
2690 which desktop environment I like and I
'm taking some refuge in Xfce
2691 while I figure that out. I like tools that keep things simple. I enjoy
2692 Python and shell scripting. I went to an Arduino workshop recently and
2693 it was awesome seeing how easy and simple the IDE software was to get
2694 up and running in Debian compared to the users running Windows and OS
2697 <p
>I also use mc which some people frown upon slightly. I got used to
2698 using Norton Commander in the early
90's and it stuck (I think the
2699 people who sneer at it is just jealous that they don
't know how to use
2702 <p
><strong
>Which strategy do you believe is the right one to use to
2703 get schools to use free software?
</strong
></p
>
2705 <p
>I think trying to force it is unproductive. I also think that in
2706 many cases it
's appropriate for schools to use non-free systems and I
2707 don
't think that there
's any particular moral or ethical problem with
2710 <p
>I do think though that free software can already solve so so many
2711 problems in educational institutions and it
's just a shame not taking
2712 advantage of that.
</p
>
2714 <p
>I also think that some curricula need serious review. For example,
2715 some areas of the world rely heavily on very specific versions of MS
2716 Office, teaching students to parrot menu items instead of learning the
2717 general concepts. I think that
's very unproductive because firstly, MS
2718 Office
's interface changes drastically every few years and on top of
2719 that it also locks in a generation to a product that might not be the
2720 best solution for them.
</p
>
2722 <p
>To answer your question, I believe that the right strategy is to
2723 educate and inform, giving someone the information they require to
2724 make a decision that would work for them.

">Debian Edu, also known as
2745 Skolelinux
</a
>, is a Linux distribution based on Debian providing an
2746 out-of-the box environment of a completely configured school
2747 network. Immediately after installation a school server running all
2748 services needed for a school network is set up just waiting for users
2749 and machines being added via GOsa², a comfortable Web-UI. A netbooting
2750 environment is prepared using PXE, so after initial installation of
2751 the main server from CD, DVD or USB stick all other machines can be
2752 installed via the network. The provided school server provides LDAP
2753 database and Kerberos authentication service, centralized home
2754 directories, DHCP server, web proxy and many other services. The

2889 pulling along to get the Wheezy based release out the door, and this
2890 time I managed to get an interview from one of the French translators
2891 in the project, Cédric Boutillier.

2895 <p
>I am
34 year old. I live near Paris, France. I am an assistant
2896 professor in probability theory. I spend my daytime teaching
2897 mathematics at the university and doing fundamental research in
2898 probability in connexion with combinatorics and statistical physics.
</p

2900 <p
>I have been involved in the Debian project for a couple of years
2901 and became Debian Developer a few months ago. I am working on Ruby
2902 packaging, publicity and translation.
</p

2904 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
2905 project?
</strong
></p
>
2907 <p
>I came to the Debian Edu project after a call for translation of
2908 <a href=
"http://wiki.debian.org/DebianEdu/Documentation/Manuals
">the
2909 Debian Edu manual
</a
> for the release of Debian Edu Squeeze. Since
2910 then, I have been working on updating the French translation of the
2913 <p
>I had the opportunity to make an installation of Debian Edu in a
2914 virtual machine when I was preparing localised version of some screen
2915 shots for the manual. I was amazed to see it worked out of the box and
2916 how comprehensive the list of software installed by default was.
</p
>
2918 <p
>What amazed me was the complete network infrastructure directly
2919 ready to use, which can and the nice administration interface provided
2920 by
<a href=
"https://oss.gonicus.de/labs/gosa/
">GOsa²
</a
>. What pleased
2921 me also was the fact that among the software installed by default,
2922 there were many
"traditional
" educative software to learn languages,
2923 to count, to program... but also software to develop creativity and
2924 artistic skills with music (
<a href=
"http://ardour.org/
">Ardour
</a
>,
2925 <a href=
"http://audacity.sourceforge.net/
">Audacity
</a
>) and
2926 movies/animation (I was especially thinking of
2927 <a href=
"http://linuxstopmotion.sourceforge.net/
">Stopmotion
</a
>).
</p
>
2929 <p
>I am following the development of Debian Edu and am hanging out on
2930 <a href=
"irc://irc.debian.org/%
23debian-edu
">#debian-edu
</a
>.
2931 Unfortunately, I don
't much time to get more involved in this
2932 beautiful project.
</p
>
2934 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
2935 Edu?
</strong
></p
>
2937 <p
>For me, the main advantages of Skolelinux/Debian Edu are its
2938 community of experts and its precise documentation, as well as the
2939 fact that it provides a solution ready to use.
</p
>
2941 <p
>I would add also the fact that it is based on the rock solid Debian
2942 distribution, which ensures stability and provides a huge collection
2943 of educational free software.
</p
>
2945 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
2946 Edu?
</strong
></p
>
2948 <p
>Maybe the lack of manpower to do lobbying on the
2949 project. Sometimes, people who need to take decisions concerning IT do
2950 not have all the elements to evaluate properly free software
2951 solutions. The fact that support by a company may be difficult to find
2952 is probably a problem if the school does not have IT personnel.
</p
>
2954 <p
>One can find support from a company by looking at
2955 <a href=
"http://wiki.debian.org/DebianEdu/Help/ProfessionalHelp
">the
2956 wiki dokumentation
</a
>, where some countries already have a number of
2957 companies providing support for Debian Edu, like Germany or
2958 Norway. This list is easy to find readily from the manual. However,
2959 for other countries, like France, the list is empty. I guess that
2960 consultants proposing support for Debian would be able to provide some
2961 support for Debian Edu as well.
</p
>
2963 <p
><strong
>Which free software do you use daily?
</strong
></p
>
2965 <p
>I am using the KDE Plasma Desktop. But the pieces of software I use
2966 most runs in a terminal: Mutt and OfflineIMAP for emails, latex for
2967 scientific documents, mpd for music. VIM is my editor of choice. I am
2968 also using the mathematical software
2969 <a href=
"http://www.scilab.org/en/scilab/about
">Scilab
</a
> and
2970 <a href=
"http://www.sagemath.org/index.html
">Sage
</a
> (built from
2971 source as not completely packaged for Debian, yet).
2973 <p
><strong
>Do you have any suggestions for teachers interested in
2974 using the free software in Debian to teach mathematics and
2975 statistics?
</strong
></p
>
2977 <p
>I do not have any
"nice
" recommendations for statistics. At our
2978 university, we use both
<a href=
"http://www.r-project.org/
">R
</a
> and
2979 Scilab to teach statistics and probabilistic simulations. For
2980 geometry, there are nice programs:
</p
>
2984 <li

"http://www.drgeo.eu/
">drgeo
</a
> and
2985 <a href=
"http://edu.kde.org/applications/all/kig

</a
> to do
2986 constructions in planar geometry
2988 <li
><a href=
"http://www.geom.uiuc.edu/software/download/kali.html
">kali
</a
>
2989 to discover symmetry groups (the so-called wallpapers and frieze
2990 groups), although the interface looks a bit old.

><strong
>Which strategy do you believe is the right one to use to

3002 <p
>My suggestions would be to
</p
>
3006 <li
>advertise the reduction of costs when free software is used.
</li

3008 <li
>communicate about the quality of free software projects, using
3009 well known examples like Firefox, ThunderBird and
3010 OpenOffice.org/LibreOffice.
</li
>
3012 <li
>advertise the living and strong community around the project.
</li

3174 <p
><strong
>Hvem er du, og hva driver du med til daglig?

3176 <p
>Jeg heter Nirosan Thiyagalingam. Jeg er
24 år og studerer
3177 dataingeniør studiet ved Høgskolen i Sør Trøndelag. Interessen for
3178 data har siden ung alder vært tilstede og jeg har i tillegg alltid
3179 vært glad i å lære nye ting. Med teknologi som endres svært hurtig er
3180 det alltid noe nytt å lære. Noe som igjen har gjort det svært
3181 interessant å følge med på utviklingen. Jeg valgte dataingeniør
3182 studiet grunnet ønske om å lære enda mer om programmering og utvikling
3183 av store systemer.
</p
>
3185 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
3187 <p
>Skolelinux prosjektet hørte jeg først om i media. Men det var først
3188 når jeg skulle velge bacheloroppgave at jeg fattet mer interesse for
3189 prosjektet. Et enkelt søk på nettet førte meg til skolelinux sine
3190 hjemmesider. Informasjonen jeg fant der gjorde meg enda nysgjerrig og
3191 jeg valgte derfor en oppgave som gikk ut på å få en
3192 <a href=
"http://www.raspberrypi.org
">Raspberry PI
</a
>. Altså en
3193 ultra-billig datamaskin til å kjøre Debian Edu på lik linje med
3194 vanlige datamaskiner. I løpet av prosjektet ble det gjort mye
3195 forskning på nettet. Det var mye jeg måtte forstå rundt hvordan
3196 operativsystemet Linux fungerte før jeg kunne angripe
3197 problemet. Prøvde først å finne ut hvordan man kunne transformere en
3198 vanlig installasjon av Skolelinux til Raspberry PI, men dette var
3199 altfor vanskelig å jeg endte opp med mer spørsmål enn svar. Det ble
3200 videre opprettet kontakt med Skolelinux utviklere på IRC der jeg fikk
3201 diskutert hvilken retning jeg burde gå for å få til en fullverdig
3202 løsning. Det ble bestemt at jeg skulle gå for å først installere
3203 <a href=
"http://www.raspbian.org/
">Raspian
</a
>. Dette er et
3204 operativsystem basert på Debian spesiallaget for Raspberry Pi sin
3205 maskinvare. Nå som Debian var installert på datamaskinen gjenstod det
3206 å installere de nødvendige Skolelinux pakkene for å få til et
3207 fullverdig system. Disse pakkene ble installert manuelt i første
3208 omgang, men ble senere installert automatisk via et script som Petter
3209 Reinholdtsen laget. Dette scriptet er så enkel å bruke at man er i
3210 gang med installasjonen i løpet av bare
5 minutter. Ikke nok med det,
3211 alt skjer helt automatisk. Alt i alt er jeg veldig fornøyd med
3212 resultatet av installasjonsprosessen. Raspberry Pi er en veldig svak
3213 maskin og det merkes godt når man har installert Skolelinux på
3214 den. Video og
3D-rendering fungerer utrolig dårlig, men nettsurfing og
3215 kontorprogrammer fungerer godt. Det kan derfor konkluderes med at
3216 datamaskinen er egnet for enkle oppgaver.
3218 <p
>Jeg syns det er viktig påpeke at dette kun er startfasen av en slik
3219 løsning. På markedet finnes det nå maskiner som har bedre hardware enn
3220 Raspberry Pi. Det er store muligheter for at man kan klare å
3221 installere Skolelinux på disse også, og da forsvinner nok mest
3222 sannsynlig ytelsesproblemene med Video og
3D rendering også.
</p
>
3224 <p
>Det ble også prøvd med en løsning som gjorde at Raspberry Pi
3225 fungerte som en tynnklient. Denne løsningen hadde langt bedre ytelse
3226 med tanke på hastighet og brukeropplevelse. Men også her var video og
3227 3D rendering dårlig. Det ble brukt en liten Linux distribusjon kalt
3228 <a href=

</a
> for å få til
3231 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
3233 <p
>Fordelen med Skolelinux er mange. At det er gratis er en stor
3234 fordel, men at det er så mange som er med på å utvikle det og
3235 vedlikeholde det er en enda større fordel. Allerede før jeg startet
3236 med prosjektet så jeg mange fordeler, og når jeg nærmet meg sluttfasen
3237 så jeg langt flere. At prosjektet skulle inneha en så høy kvalitet
3238 hadde jeg aldri trodd. En vanlig Skolelinux installasjon har de
3239 nødvendige programmene og funksjonen som både små og store skoler i
3240 tillegg til organisasjoner kan klare seg med. At prosjektet tilbyr en
3241 så komplett løsning er en kjempefordel. Installasjonen er knirkefri
3242 og det er svært enkelt å installere og komme i gang.
</p
>
3244 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
3246 <p
>Ulempene jeg ser med prosjektet er ryddigheten av websidene. Selv
3247 om websidene er enkle og konsise er det allikevel ikke appellerende i
3248 like stor grad som for eksempel
3249 <a href=
"http://www.ubuntu.com
">Ubuntu
</a
> sine sider. Deres side
3250 tilbyr, i tillegg til godt design og presentasjon, en nettbasert
3251 emulator av deres operativsystem. Dette er en stor fordel slik jeg ser
3252 det. Bortsett fra dette ser jeg absolutt ingen ulemper med
3253 Skolelinux-prosjektet.
</p
>
3255 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
3257 <p
>Til daglig er jeg en flittig bruker av det åpne media
3258 sentersystemet
<a href=
"http://xbmc.org/
">XBMC
</a
>. Det enorme
3259 samfunnet rundt dette prosjektet har gjort dette til et program som
3260 dekker alles behov. Man kan tilpasse det akkurat slik man vil både med
3261 tanke på utseende og funksjoner ved installere plug-ins eller
3264 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
3265 skoler til å ta i bruk fri programvare?
</strong
></p
>
3267 <p
>Strategien som burde brukes sett fra mine øyne er
3268 markedsføring. Jeg er sikker på at om flere skoler fikk et lite innsyn
3269 i hvor bra Skolelinux er så ville de ikke nølt med å gå over fra noe
3270 annet som koster de store summer. At skolelinux til de grader tilbyr
3271 en så komplett løsning bure komme frem. Enten via reklamekampanjer
3272 eller ved å sende ut folk til skoler for så å la skolenettverk
3273 ansvarlige få teste ut hvordan Skolelinux fungerer i praksis. Om det
3274 i tillegg ble utviklet gode websider og en emulator for å la brukere
3275 prøve operativsystemet ville nok dette ha styrket inntrykket
3276 betraktelig.

3286 an operating system based on Debian intended for use in schools. It
3287 contain a turn-key solution for the computer network provided to
3288 pupils in the primary schools. It provide both the central server,
3289 network boot servers and desktop environments with heaps of
3290 educational software. The project was founded almost
12 years ago,
3291 2001-

3292 cash to fund developer gatherings and other project related activity,

>A topic that come up again and again on the Debian Edu mailing
3297 lists and elsewhere, is the question on how to transform a Debian or
3298 Ubuntu installation into a Debian Edu installation. It isn
't very
3299 hard, and last week I wrote a script to replicate the steps done by
3300 the Debian Edu installer.
</p

3302 <p
>The script,
3303 <a href=
"http://anonscm.debian.org/viewvc/debian-edu/branches/wheezy/debian-edu-config/share/debian-edu-config/tools/debian-edu-bless?view=markup
">debian-edu-bless
<a/
>
3304 in the debian-edu-config package, will go through these six steps and
3305 transform an existing Debian Wheezy or Ubuntu (untested) installation
3306 into a Debian Edu Workstation:
</p
>
3310 <li
>Add skolelinux related APT sources.
</li
>
3311 <li
>Create /etc/debian-edu/config with the wanted configuration.
</li
>
3312 <li
>Install debian-edu-install to load preseeding values and pull in
3313 our configuration.
</li
>
3314 <li
>Preseed debconf database with profile setup in
3315 /etc/debian-edu/config, and run tasksel to install packages
3316 according to the profile specified in the config above,
3317 overriding some of the Debian automation machinery.
</li
>
3318 <li
>Run debian-edu-cfengine-D installation to configure everything
3319 that could not be done using preseeding.
</li
>
3320 <li
>Ask for a reboot to enable all the configuration changes.
</li
>
3324 <p
>There are some steps in the Debian Edu installation that can not be
3325 replicated like this. Disk partitioning and LVM setup, for example.
3326 So this script just assume there is enough disk space to install all
3327 the needed packages.

3370 <p
>Debian Edu, also known as Skolelinux, is a Linux distribution based
3371 on Debian providing an out-of-the box environment of a completely
3372 configured school network. Immediatly after installation a school
3373 server running all services needed for a school network is set up just
3374 waiting for users and machines being added via GOsa², a comfortable
3375 Web-UI. A netbooting environment is prepared using PXE, so after
3376 initial installation of the main server from CD, DVD or USB stick all
3377 other machines can be installed via the network.
</p

>This is the first test release based on Wheezy (which currently is
3380 not released yet). Basically this is an updated and slightly improved

3464 i Narvikskolene og konstnaden ved å gå over til Windows. For litt

3473 <p
>Notatet forteller at Narvik ville måtte betalt minst
9 millioner
3474 for å gå over til Windows på skolene. I tillegg dokumenterer notatet
3475 at læreplanens krav oppfylles uten problemer ved bruk av Skolelinux.
3476 Jeg anbefaler alle å lese de
10 sidene med gode argumenter for å kutte
3477 unødige utgifter på IT i skoleverket. :)

6. He installed the standalone profile and
3663 the video show a walk-through of of the menu content, demonstration of
3664 a few programs and his view of our distribution.
</p

3666 <p
>There is also some really nice quotes (transcribed by me, might
3667 have heard wrong). While looking thought the Graphics menu:
</p
>
3670 "Basically everything you ever need in a school environment.
"
3673 <p
>And as a general evaluation of the entire distribution:
</p
>
3676 "So, yeah, a bit bloated. It kept all the Debian stuff in there, just
3677 to keep it nice and GNU. So, I do not want to go on about it, but
3678 lets give it
7 out of
10. I am not going to use it. That is because
3679 I am not deploying a school network. There may be some mythical
3680 feature to help you deploy Skolelinux on a school network.
"
3683 <p
>To bad he did not test the server profile, and discovered the PXE
3684 installation option. It make it possible to install only the main
3685 server from CD, and the rest of the machines via the net, and might be
3686 considered the mythical feature he talk about. :)
</p
>
3688 <p
>While looking through the menus, there is also this funny comment
3689 about the part of the K menu generated from the Debian menu subsystem:
3692 "[The K menu] have a special Debian section for software that no-one

>Etter en lang pause og travle uker har jeg endelig klart å få
3814 samlet et nytt intervju med en av folkene i
3815 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet.
3816 Denne gang er det Helge Tore Høyland, en mangeårig bidragsyter på
3817 epostlistene og ellers i prosjektet.
</p
>
3819 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
3821 <p
>Eg er IT-konsulent/teknikker hjå eit firma i Steinkjer med navn
3822 <a href=
"http://unoit.no/
">Uno IT
</a
>. Uno IT er eit lite firma som
3823 drifter nettverk og maskiner for små og mellomstore firma
3824 Steinkjer-området. Per dags dato er me
2 ansatte. Min faglege bakgrunn
3825 er Fagbrev som it-teknikker, samt nokre fag innen nettverk- og
3826 server-drift frå HiST og NTNU. Dagleg arbeid består i oppsett av nye
3827 maskiner og hjelp til sluttbrukere, samt oppsett og vedlikehold av eit
3828 vidt spekter av fagsystemer ute hjå kunder. Erfaring med Skolelinux
3829 har eg hatt i forbindelse med drifting av
3830 <a href=
"http://www.bjorkly.no/
">Bjørkly skule
</a
>, ein privat
3831 grunnskule i Namsos-området. I dag har skulen
65 elever,
15 lærere,
1
3832 hovedserver og ca
60 klienter som kjører halvtjukt. Eg har bygd og
3833 driftet systemet sidan summaren
2006.
</p
>
3835 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
3837 <p
>Eg kom i kontakt med Skolelinux-prosjektet via ein artikkel i eit
3838 fagblad, som eg ikkje lenger hugsar namnet på. I og med at eg allereie
3839 hadde pusla med nettverk for ein annan skule, fatta eg straks
3840 interesse for prosjektet.
</p
>
3842 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
3844 <p
>Fordelane med Skolelinux er sentralisert administrasjon og svært
3845 mange gode verktøy «ut av boksen». Veldig kjekt å kunne drifte
60
3846 klientar med berre å «bry» seg med ein server. Levetid for systemets
3847 hardware er og ein veldig fin effekt. I tillegg kjem fordelar som økt
3848 sikkerhet og mindre lisenskostnader. Etter min erfaring er det og
3849 mykje mindre driftskostnader med eit slikt system enn konkurrerande
3850 system, pga enkelhet med sentralisert administrasjon. På grunn av at
3851 Skolelinux er basert på Debian er det òg svært stabilt.
</p
>
3853 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
3855 <p
>Ulemper er mangel på vilje til å følge standarer ute i markedet,
3856 som fører til mangel på støtte til nokre mykje brukte ting. Flash og
3857 Java er typiske eksempel. Sidan Debian satsar på stabilitet framfor å
3858 ha nyeste pakke av eit program, kan ein i nokre tilfeller kome borti
3859 at program vert «for gamle». Det er spesielt nettlesaren som er
3860 utsett. Mangel på vilje til å utvikle pedagogisk programvare, i Noreg,
3861 for «alle» platformer fører òg til noko hovudbry.
</p
>
3863 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
3865 <p
>Til dagleg bruker eg svært mange forskjellige «fri programvare»
3866 program. Firefox, Thunderbird, Freecommander, ImgBurn, Clonezilla,
3867 OCS inventory, Icinga, Skolelinux, SystemRescueCD og mykje meir.
</p
>
3869 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
3870 skoler til å ta i bruk fri programvare?
</strong
></p
>
3872 <p
>Strategisk må ein fokusere på at sluttbruker eigentleg ikkje er så
3873 fokusert på at det er fri programvare men at det skal «berre fungere».
3874 Gjer det enkelt å bruker og ikkje minst å administrere. For Skolelinux
3875 sin del må ein få eit betre fokus på overganger. Utbytting av servere
3876 må gå meir automatisk, import og eksport av brukerbase og maskinbase
3877 med meir må kunne gå enkelt og oppgradering til neste versjon må bli
3878 mykje meir automatisk og gjennomtesta. Ein må unngå at ein må sette
3879 opp frå start når ein byter ut ein server eller oppgraderer til neste
3880 versjon. For å få Skolelinux til å bli eit betre alternativ for skular
3881 må ein ha fokus på nettlesaren. Denne må bli «up to date» og støtte
3882 dei protokollar og tillegg som vert brukt av forlag med meir. Etter
3883 kvart som meir og meir blir flytta ut i «skya» vert dette viktigare og
3884 viktigare. Ein kunne ynskje og jobbe for at forlag med fleire tar i
3885 bruk opne standarer, men inntil det skjer, må systemet kunne brukast
3886 mot desse fagsystema.
</p
>
3888 <p
>For meg har prosjektet med Skolelinux vore ein svært artig og
3889 lærerik prosess. Miljøet rundt er ikkje enormt stort, dog stort nok,
3890 men det er svært hjelpevillig og engasjert.

3904 present. As the Debian Edu / Skolelinux project is very short on
3905 funding these days, and thus lack the money to do regular developer
3906 gatherings, this donation was most welcome. One developer gathering
3907 cost around NOK
15&nbsp;
000,-, so we need quite a lot more to keep the
3908 development pace we want. Thus, I hope their example this year is
3909 followed by many others. :)

3927 interesting, as I am involved with several organizations where
3928 accounting is an issue, and I have not really become too friendly with
3929 the different web based systems we use. I find it hard to find what I
3930 look for in the menus and even harder try to get sensible data out of
3931 the systems. Ledger seem different. The accounting data is kept in
3932 text files that can be stored in a version control system, and there
3934 are at least
<a href=

3935 different implementations

3994 <p
>I am a
39-year-old woman living in the very north of Germany near
3995 Denmark. I live in a patchwork family with
"my man
" Mike Gabriel, my
3996 two daughters, Mikes daughter and Mikes and my rather newborn son.
3998 <p
>At the moment - because of our little baby - I am spending most of
3999 the day by being a caring and organising mom for all the kids.
4000 Besides that I am really involved into and occupied with several inner
4001 growth processes: New born souls always bring the whole familiar
4002 system into movement and that needs time and focus ;-). We are also
4003 in the middle of buying a house and moving to it.
</p
>
4005 <p
>In
2013 I will work again in my job in a German foundation for
4006 nature conservation. I am doing public relation work there. Besides
4007 that - and that is the connection to Skolelinux / Debian Edu - I am
4008 working in our own school project
"IT-Zukunft Schule
" in North
4009 Germany. I am responsible for the quality assurance, the customer
4010 relationship management and the communication processes in the

2001 I constantly have been training myself in communication

</strong

4020 <p
>I fell in love with Mike ;-).
</p
>
4022 <p
>Very soon after getting to know him I was completely enrolled into
4023 Free Software. At this time Mike did IT-services for one newly
4024 founded school in Kiel. Other schools in Kiel needed concepts for
4025 their IT environment. Often when Mike came home from working at the
4026 newly founded school I found myself listening to his complaints about
4027 several points where the communication with the schools head or the
4028 teachers did not work. So we were clear that he would not work for
4029 one more school if we did not set up a structure for communication
4030 between him, the schools head, the teachers, the students and the
4033 <p
>Together with our friend and hardware supplier Andreas Buchholz we
4034 started to get an overview of free software solutions suitable for
4035 schools. One day before Christmas
2010 Mike and I had a date with Kurt
4036 Gramlich in Gütersloh. As Kurt and I are really interested in building
4037 networks of people and in being in communication we dived into
4038 Skolelinux and brought it to the first grammar schools in Northern

4049 answer comes rather from a social point of view.

4051 <p
>The biggest advantage of Skolelinux / Debian Edu I see is the large
4052 and strong international community of Debian Developers in the
4053 background which is very alive and connected over mailinglists, blogs
4054 and meetings. My constant feeling for the Debian Community is: If
4055 something does not work they will somehow fix it. All is well
4056 ;-). This is of course a user experience. What I also get as a big
4057 advantage of Skolelinux / Debian Edu is that everybody who uses it and
4058 works with it can also contribute to it - that includes students,
4059 teachers, parents...

4067 <p

4068 the group of developers for Debian Edu and the people who make the
4069 marketing, that means the people that bring Skolelinux to the
4070 schools. There is a lack of communication between these two groups and
4071 I think that does not really work for Skolelinux / Debian Edu.

4073 <p
>Further I appreciate that Skolelinux / Debian Edu is known as a
4074 do-ocracy. Nevertheless I keep asking myself if at some points a
4075 democracy or some kind of hierarchical project structure would be good
4076 and helpful. I am also missing some kind of contact between the
4077 Skolelinux / Debian Edu communities in Europe or on an international
4078 level. I think it would be good if there was more sharing between the
4079 different countries using Skolelinux / Debian Edu.

4091 <p

"IT-Zukunft
4092 Schule
" we have developed (and keep developing) a great way to get
4093 schools to use Free Software. We have written a detailed concept for
4094 that so I cannot explain the whole thing here. But in a nutshell the
4095 strategy has three crucial pillars:
</p
>
4099 <li
>We really take time to get what sort of stories, questions and
4100 concerns the schools head and the teachers have about using different
4101 kinds of IT and we take time to enrol them into Free Software.
</li
>
4103 <li
>Our solution for schools is never just technical. In the centre
4104 are always the people who are going to use the software. From the very
4105 beginning of the planning for a school, we tell the schools head that
4106 they are paying us not only for a technical solution for their school,
4107 they also pay us for leading all the communication processes
4108 needed. If they do not want that, we are not working with them because
4109 we cannot give a guarantee for the quality of our work then.
</li
>
4111 <li
>Another focus lies in the training of teachers and students in
4112 co-administrating the IT-System at their school. They start getting in
4113 contact with the Skolelinux / Debian Edu community and they get the
4114 offer to become more and more independent from us.

4137 <p
>I sommer (
2012-
07-
23) hadde Fremover et oppslag om at Narvik
4138 kommune hadde spart mellom
10 og
20 millioner kroner de siste årene på
4139 å bruke Skolelinux på sine skoler. Harstad har også tatt i bruk
4140 Skolelinux på alle sine skoler. Som tidligere Ballangsværing gledet
4141 det meg stort å se at skoleløsningen vi har utviklet siden
2001 tas i
4142 bruk i området der jeg vokste opp, og dermed bidrar til en bedre og
4143 billigere skolehverdag.
</p
>
4145 <p
>Skolelinux er en komplett IT-løsning for elevnettverket på en
4146 skole, med både nettverkstjenester og løsning for elevmaskiner med
4147 pedagogisk programvare, som tillater en å øke levetiden på en
4148 datamaskin i skolen med mange år. En undersøkelse publisert i mars
4149 2012 viste at de
56 norske skolene som har offentliggjort at de bruker
4150 Skolelinux eller annen Linuxutgave hadde
36% større PC-tetthet enn
4151 landsgjennomsnittet, når en ser på tall rapportert til Grunnskolens
4152 Informasjonssystem. I følge Paul Reidar Løsnesløkken, IKT-konsulent i
4153 Nord-Odal, fungerer datamaskiner godt til de er
8 til
10 år gamle.
</p
>
4155 <p
>I høst (
2012-
09-
29) fortalte Fremover hvordan Ballangen kommune har
4156 opparbeidet seg
20 millioner i underskudd og nok havner på Robek-lista
4157 fra nyttår. Kanskje Ballangen også burde ta i bruk Skolelinux for å
4158 spare penger? Hvis kommunen mangler kompetanse lokalt på Linux finnes
4159 det kommersielle selskaper som tilbyr driftstjenester rundt
4160 Skolelinux, og jeg bør vel avsløre at jeg selv er involvert i et av
4161 dem, Skolelinux Drift AS. Kommunen kan dermed få hjelp hvis de ikke
4162 ønsker å bygge opp egen kompetanse.

4331 community, I finally found time to wrap up another. This time it is
4332 Giorgio Pioda, which showed up on the mailing list at the start of
4333 this year, asking questions and inspiring us to improve the first time
4334 administrators experience with Skolelinux. :) The interview was
4335 conduced in May, but I only found time to publish it now.

>I have a PhD in chemistry but since several years I work as teacher
4340 in secondary (
15-
18 year old students) and tertiary (a kind of
"light
"
4341 university) schools. Five years ago I started to manage a Learning
4342 Management Service server and slowly I got more and more involved with
4343 IT.
3 years ago the graduating schools moved completely to Linux and I
4344 got the head of the IT for this. The experience collected in chemistry
4345 labs computers (for example NMR analysis of protein folding) and in
4346 the IT-courses during university where sufficient to start. Self
4347 training is anyway very important
</p

4349 <p
>I live in the Italian speaking part of Switzerland, and the
4350 <a href=

">SPSE school
</a
> (secondary) is a very
4351 special sport school for young people who try to became sport pro (for
4352 all sports, we have dozens of disciplines represented) and we are
4353 recognised by the Olympic Swiss Organisation.

4356 project?
</strong
></p
>
4358 <p
>Looking for Linux / Primary Domain Controller (PDC) I found it
4359 already several years ago. But since the system was still not
4360 Kerberized and since our schools relies strongly on laptops I didn
't
4361 use it. I plan to introduce it in the next future, probably for the
4362 next school year, since the squeeze release solved this security
4365 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4366 Edu?
</strong
></p
>
4368 <p
>Many. First of all there is a strong and living community that is
4369 very generous for help and hints. Chat help is crucial, together with
4370 the mailing list. Second. With Skolelinux you get an already well
4371 engineered platform and you don
't have to start to build up your PDC
4372 and your clients from GNU/scratch; I
've already done this once and I
4373 can tell it, it is hard. Third, since Skolelinux is a standard
4374 platform, it is way easier to educate other IT people and even if the
4375 head IT is sick another one could pick up the task without too much
4378 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
4379 Edu?
</strong
></p
>
4381 <p
>The only real problem I see is that it is a little too less
4382 flexible at client level. Debian stable is rocky and desirable, but
4383 there are many reasons that force for another choice. For example the
4384 need of new drivers for new PC, or the need for a specific OS for some
4385 devices that have specific software packages for another specific
4386 distribution (I have such a case for whiteboards that have only
4387 Ubuntu packages). Thus, I prepared compatibility packages educlient
4388 and eduroaming, hoping not to use them ;-)
</p

4390 <p
><strong
>Which free software do you use daily?
</strong
></p
>
4392 <p
>I have a Debian Stable PDC at school (Kerberos, NIS, NFS) with
4393 mixed Debian and Ubuntu clients. If you think that this triad
4394 combination is exotic... well I discovered right yesterday that
4395 <a href=
"http://moo.nac.uci.edu/~hjm/Perceus-Report.html
">Perceus
</a
>
4396 has the same...
</p
>
4398 <p
>For myself I run Debian wheezy/sid, but this combination is good
4399 only I you have enough competence to fix stuff for yourself, if
4400 something breaks. Daily I use texmacs, gnumeric, a little bit of R
4401 statistics, kmplot, and less frequently OpenOffice.org.
</p
>
4403 <p
><strong
>Which strategy do you believe is the right one to use to
4404 get schools to use free software?
</strong
></p
>
4406 <P
>I think that the only real argument that school managers
"hear
" is
4407 cost reduction. They don
't give too much weight on quality, stability,
4408 just because they are normally not open to change.
</p
>
4410 <p
>Students adapts very quickly to GNU/Linux (and for them being able
4411 to switch between different OS is a plus value); teachers and managers
4412 don
't.
</p
>
4414 <p
>We decided to move to Linux because students at our school have own
4415 laptop and we have the responsibility to keep the laptop ready to use;
4416 we were really unsatisfied with Microsoft since every Monday we had
20
4417 machine to fix for viral infections... With Linux this has been
4418 reduced to zero, since people installs almost only from official
4419 repositories. I think that our special needs brought us to Linux.
4420 Those who don
't have such needs will hardly move to Linux.

4439 Skolelinux er en stor suksess i Narvik siden det ble tatt i bruk i
4440 2004. Her er noen fine sitater:
</p
>
4443 "- Skolelinux har spart kommunen for store pengesummer, millionbeløp,
4444 som de heller kan bruke på andre ting, sier IKT-konsulent Viggo
4448 <p
>Avisen forteller at de har fått tilgang til beregninger som viser
4449 at Narvik kommune har spart noe mellom
10 og
20 millioner kroner de
4450 siste
8 årene på å bruke Skolelinux, og fortsetter:
</p
>
4454 "Regnestykket tar høyde for sparte kostnader til lisenser som medfølger
4455 de alternative operativsystemene, lavere driftskostnader og lengre
4456 levetid på datautstyret. Totalt har Narvikskolen en maskinpark på
4457 1600 maskiner fordelt på de
11 skolene fra Skjomen i sør til Bjerkvik
4462 <p
>Viggo Fedreheim sier dette om hvor noe av gevinsten kommer fra:
</p
>
4465 "- Vi kan gjenbruke gamle maskiner i skolen som er for dårlig andre
4466 steder i kommunen der de ikke bruker Skolelinux. Levetiden på en
4467 datamaskin blir
3-
5 år lenger med Skolelinux. Vi kaller det for
4468 grønn IT, miljøvennlig IT.
"
4471 <p
>Her er det mulighet for flere kommuner å få et godt IT-system på
4472 skolene, hvis de er villige til å forsøke. De som ikke har kompetanse
4473 innomhus kan kjøpe det fra en av de kommersielle leverandørene av

>I
'm a
44 year old country guy that have been working
12 years at
4549 the same school as
50% IT-manager and
50% Teacher. My educational
4550 background is fil.kand in history and religious beliefs, an exam as a
4551 "folkhighschool
" teacher, that is, for teaching grownups. In
4552 Norwegian I believe it
's called
"Vuxenupplaring
". I also have a master
4553 in
"Technology and social change
". So I
'm not really a tech guy, I
4554 just like to study how humans and technology interact and that is my
4555 perspective when working with IT.
</p
>
4557 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4558 project?
</strong
></p
>
4560 I have followed the Skolelinux project for quite some time by
4561 now. Earlier I tested out the K12-LTSP project, which we used for some
4562 time, but I really like the idea of having a distribution aimed to be
4563 a complete solution for schools with necessary tools integrated. When
4564 K12-LTSP abandoned that idea some years ago, I started to look more
4565 seriously into Skolelinux instead.
4567 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4568 Edu?
</strong
></p
>
4570 The big point of Skolelinux to me is that it is a complete
4571 distribution, ready to install. It has LDAP-support, MS Windows
4572 integration tools and so forth already configured, saving an
4573 administrator a lot of time and headache. We were using another Linux
4574 based thin-client system called Thinlinc, that has served us very
4575 well. But that Skolelinux is based on VNC and LTSP, to me, is better
4576 when it comes to the kind of multimedia used in schools. That is
4577 showing videos from Youtube or educational TV. It is also easier to
4578 mix thin clients with workstations, since the user settings will be the
4579 same. In our VNC-based solution you had to
"beat around the bush
" by
4580 setting up a second, hidden, home-directory for user settings for the
4581 workstations, because they will be different from the ones used on the
4582 thin clients. Skolelinux support for diskless workstations are very
4583 convenient since a school today often need to use a class room
4584 projector showing videos in full screen. That is easily done with a
4585 small integrated media computer running as a diskless workstation. You
4586 have only two installs to update and configure. One for the thin
4587 clients and one for the workstations. Also saving a lot of time. Our
4588 old system was also based on Redhat and CentOS. They are both very
4589 nice distributions, but they are sometimes painfully slow when it
4590 comes to updating multimedia support and multimedia programs (even
4591 such as Gimp), leaving us with a bit
"oldish
" applications. Debian is
4594 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
4595 Edu?
</strong
></p
>
4597 <p
>Debian is a bit too quick when it comes to updating. As an example
4598 we use old HP terminals as thinclients, and two times already this
4599 year (
2012) the updates you get from the repositories has stopped
4600 sound from working with them. It
's a kernel/ALSA issue. So you have
4601 to be more careful properly testing the updates before you run them in
4602 a production environment. This has never happened with CentOS.
</p
>
4604 <p
>I also would like to be able to set my own domain-settings at
4605 install time. In Skolelinux they are kind of hard coded into the
4606 distribution, when it comes to LDAP and at least samba integration.
4607 That is more a cosmetic/translation issue, and not a real problem.
4608 Running MS Windows applications within the Skolelinux environment needs
4609 to be better supported. That is, running them seamlessly via RDP, and
4610 support for single-sign on. That will make the transition to free
4611 software easier, because you can keep the applications you really
4612 need. No support will make it impossible if you work in a school where
4613 some applications can
't be open source. As for us we really need to
4614 run Adobe InDesign in our journalist classes. We run a journalist
4615 education, and is one of the very few non university ones that is ok:d
4616 by Svenska journalistförbundet (Swedish journalist association). Our
4617 education gives the pupils the right of membership there, once they
4618 are done. This is important if you want to get a job.
</p
>
4620 <p
>Adobe InDesign is the program most commonly used in newspapers and
4621 magazines. We used Quark Express before, but they seem to loose there
4622 market to Adobe. The only
"equivalent
" to InDesign in the opensource
4623 world is Scribus, and its not advanced enough. At least not according
4624 to the teacher. I think it would be possible to use it, because they
4625 are not supposed to learn a program, they are supposed to learn how to
4626 edit and compile a newspaper. But politically at our school we are not
4627 there yet. And Scribus lacks a lot of things you find i InDesign.
</p
>
4629 <p
>We used even a windows program for sound editing when it comes to
4630 the radio-journalist part. The year to come we are going to try
4631 Audacity. That software has the same kind of limitations compared to
4632 Adobe Audition, but that teacher is a bit more open minded. We have
4633 tried Ardour also, but that instead is more like a music studio
4634 program, not intended for the kind of editing taking place in a radio
4635 studio. Its way to complex and the GUI is to scattered when you only
4636 want to cut, make pass-overs, add extra channels and normalise. Those
4637 things you can do in Audacity, but its not as easy as in Audition. You
4638 have to do more things manually with envelopes, and that is a bit old
4639 fashion and timewasting. Its also harder to cut and move sound from
4640 one channel to another, which is a thing that you do frequently
4641 because you often find yourself needing to rearrange parts of the
4642 sound file.
</p
>
4644 <p
>So, I am not sure we will succeed in replacing even Audition, but we
4645 will try. The problem is the students have certain expectations when
4646 they start an education towards a profession. So the programs has to
4647 look and feel professional. Good thing with radio, there are many
4648 programs out there, that radio studios use, so its not as standardised
4649 as Newspaper editing. That means, it does not really matter what
4650 program they learn, because once they start working they still have to
4651 learn the program the studio uses, so instead focus has to be to learn
4652 the editing part without to much focus on a specific software.

4654 <p
><strong
>Which free software do you use daily?
</strong
></p

4656 <p
>Myself I
'm running Linux Mint, or Ubuntu these days. I use almost
4657 only open source software, and preferably Linux based. When it comes
4658 to most used applications its OpenOffice, and Firefox (of course ;)
4661 <p
><strong
>Which strategy do you believe is the right one to use to
4662 get schools to use free software?
</strong
></p
>
4664 <p
>To get schools to use free software there has to be good open
4665 source software that are windows based, to ease the transition. But
4666 it
's also very important that the multimedia support is working
4667 flawlessly. The problems with Youtube, Twitter, Facebook and whatever
4668 will create problems when it comes to both teachers and
4669 students. Economy are also important for schools, so using thin
4670 clients, as long as they have good multimedia support, is a very good
4671 idea. It
's also important that the open source software works even for
4672 the administration. It
's hard to convince the teachers to stick with
4673 open source, if the principal has to run Windows. It also creates a
4674 problem if some classes has to use Windows for there tasks, since that
4675 will create a difference in
"status
" between classes, so a good
4676 support for running windows applications via the thin client (Linux)
4677 desktop is essential. At least at our school, where we have mixed
4678 level of educations, from high-school to journalist-school.

4698 of the major blockers for the project success is the purchasing skills

4700 Debian Edu / Skolelinux say they need and to a lower cost than the
4701 alternatives, and yet so few schools decide to use our solution. I

4916 Ulsrud VGS i Oslo. Senere eide og jobbet jeg flere år i Linuxlabs AS,
4917 som jeg solgte til Redpill Linpro AS (den gangen Linpro AS). I dag

4923 <p
>Fruen og jeg dro på en lengre seiltur i
2000, der jeg måtte ha
"noe
4924 å gjøre
" under hjemturen over Atlanteren. Jeg kjøpte et par bøker om
4925 Linux i en bokhandel i New York og ble veldig fascinert. Etter
4926 hjemkomsten begynte jeg å jobbe på Ulsrud VGS, som naturfagslærer, men
4927 som IT-interessert ble jeg fort en del av den nye IT-satsningen som
4928 skulle løfte Ulsrud og gi skolen en bedre rykte. Vi hadde ganske
4929 mange maskiner, som gikk på Win98 og to servere som ble oppgradert til
4930 Win2000. Systemene var ustabil og dårlige. På leting etter noe
4931 bedre, uten å knekke ryggen økonomisk, kom jeg over
"Linux i Skolen
"
4932 og Skolelinux. Jeg tok kontakt med miljøet og en gjeng møtte opp på
4933 skolen, der vi gjorde en liten testinstallasjon. Etter et par år var
4934 ryggraden på skolen Linux (Skolelinux) og vi hadde flere hundre
4935 maskiner, både tynne klienter (gamle og nye), bærbare (Debian) og noen
4936 stasjonære (Win2000). På et tidspunkt var Ulsrud den råeste IT-skolen
4937 og det irriterte skolesjefen i Oslo, da de satset hardt på

</strong
></p

4942 <p
>Det som gjorde at vi fikk inn Skolelinux var ene og alene
4943 økonomiske. Det faktum at vi slapp å kjøpe masse nye lisenser og at
4944 vi kunne bruke gammel hardware. Alt i alt gjorde dette at vi sparte
4945 mye, men i stede for å bruke mindre på IT brukte vi det vi sparte på å
4946 skaffe mer hardware og på den måten gi det beste tilbudet i landet til
4947 våre elever. For oss som driftet var det himmel å ha et system som
4948 gikk å administrere sentralt og effektivt. Det var heller ikke så
4949 dumt at vi kunne
"låse
" maskinene mer effektivt enn vi kunne med
4950 Microsoft Windows, slik at vi slapp mye feil og problemer som ble
4951 forårsaket av
"kreative
" elever.

4955 <p
>Det vi slet med var mangelen av en del programmer lærerne ville ha.
4956 Husker ikke alle, men det var et knippe med pedagogiske programmer de
4957 ikke fikk. I dag tror jeg det problemet er langt mindre da det meste
4958 av disse kjøres gjennom nettleseren.

4962 <p

4963 både OpenOffice, Firefox og en del andre programmer på den bærbare.
4964 Firefox brukes mest av disse. På Apple-serveren hjemme bruker jeg
4965 HandBrake mye, og jeg har installert OpenWRT på flere av
4966 basestasjonene både hjemme og på jobben. I tillegg til det har jeg i
4967 flere år finansiert et prosjekt som heter
4968 <a href=
"http://www.found.no/
">Found IT
</a

4969 vi lager et rammeverk for søk, der alt vi bruker fri programvare. Det

4973 skoler til å ta i bruk fri programvare?

4975 <p
>Når det gjelder IT og skole er fortsatt økonomi veldig viktig. Så
4976 man må oppfylle minimumskravene (ikke være best, men bra nok) og selge
4977 seg inn på hvor mye man sparer. Det betyr selvsagt at man sparer på
4978 lisenser, men også på driftsinnsats. Men nå når jeg ikke er en aktiv
4979 del av miljøet lenger hører jeg nesten ingen ting om fri programvare.
4980 Jeg stiller meg da spørsmålet om det har blitt stille rundt miljøet,
4981 eller om jeg kun så det tydeligere før når jeg var aktiv? Uansett er
4982 det for stille rundt Skolelinux-prosjektet nå.

4992 another interview with the people behind
4993 <a href=
"http://www.skolelinux.org/
">Debian Edu and Skolelinux
</a
>.
4994 This time we get to know José Luis Redrejo Rodríguez, one of our great
4995 helpers from Spain. His effort was the reason we added support for
4996 several desktop types (KDE, Gnome and most recently LXDE) in Debian
4997 Edu, and have all of these available in the recently published

</p

5001 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
5003 <p
>I
'm a father, teacher and engineer who is working for the Education
5004 ministry of the Region of Extremadura (Spain) in the implementation of
5005 ICT in schools
</p
>
5007 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5008 project?
</strong
></p
>
5010 <p
>At
2006, I verified that both, we in Extremadura and Skolelinux
5011 project, had been working in parallel for some years, doing very
5012 similar things, using very similar tools and with similar targets, so
5013 I decided it was time to join forces as much as possible.
</p
>
5015 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5016 Edu?
</strong
></p
>
5018 <p
>A community of highly skilled experts working together, with a
5019 really open schema of collaboration and work. I really love the
5020 concepts of Do-ocracy and Merit-ocracy and the way these concepts are
5021 been used everyday inside Debian Edu.
</p
>
5023 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
5024 Edu?
</strong
></p
>
5026 <p
>Sometimes the differences in the implementations, laws or
5027 economical and technical resources in the different countries don
't
5028 allow us to agree in the same solution for all of us, and several
5029 approaches are needed, what is a waste of effort. Also, there is a
5030 lack of more man power to be able to follow the fast evolution of the
5031 technologies in school.
</p
>
5033 <p
><strong
>Which free software do you use daily?
</strong
></p
>
5035 <p
>Debian, of course, and due to my kind of job I am most of my time
5036 between Iceweasel,
<a href=

">Geany
</a

">Terminator
</a
>.
</p
>
5039 <p
><strong
>Which strategy do you believe is the right one to use to
5040 get schools to use free software?
</strong
></p
>
5042 <p
>I think there is not a single strategy because there are very
5043 different scenarios: schools with mixed proprietary and free
5044 environments, schools using only workstations, other schools using
5045 laptops, netbooks, tablets, interactive white-boards, etc.
</p
>
5047 <p
>Also the range of ages of the students is very broad and you can
5048 not use the same solutions for primary schools and secondary or even
5049 universities. So different strategies are needed.
</p
>
5051 <p
>But, looking at these differences, and looking back to the things
5052 we
've done and implemented, and the places were we have spent most of
5053 our forces, I think we should focus as much as possible in free
5054 multi-platform environments, using only standards tools, and moving
5055 more and more to Internet or network solutions that could be deployed
5056 using wireless. I think we
'll see more and more personal devices in
5057 the schools, devices the students and teachers will take home with
5058 them, so the solutions must be able to be taken at home and continue
5059 working there.

">Debian Edu
5070 based on Squeeze
</a
>, I came across some issues that should be
5071 addressed in the Wheezy release. I finally found time to wrap up my
5072 notes and provide quick summary of what I found, with a bit
5073 explanation.
</p
>
5077 <li
>We need to rewrite our package installation framework, as tasksel
5078 changed from using tasksel tasks to using meta packages (aka packages
5079 with dependencies like our education-* packages), and our installation
5080 system depend on tasksel tasks in
5081 /usr/share/tasksel/debian-edu-tasks.desc for package
5082 installation.
</li
>
5084 <li
>Enable Kerberos login for more services. Now with the Kerberos
5085 foundation in place, we should use it to get single sign on with more
5086 services, and avoiding unneeded password / login questions. We should
5087 at least try to enable it for these services:
5090 <li
>CUPS for admins to add/configure printers and users when using
5092 <li
>Nagios for admins checking the system status.
</li
>
5093 <li
>GOsa for admins updating LDAP and users changing their passwords.
</li
>
5094 <li
>LDAP for admins updating LDAP.
</li
>
5095 <li
>Squid for users when exam mode / filtering is active.
</li
>
5096 <li
>ssh for admins and users to save a password prompt.
</li
>
5098 </ul
></li
>
5100 <li
>When we move GOsa to use Kerberos instead of LDAP bind to
5101 authenticate users, we should try to block or at least limit access to
5102 use LDAP bind for authentication, to ensure Kerberos is used when it
5103 is intended, and nothing fall back to using the less safe LDAP bind
</li
>
5105 <li
>Merge debian-edu-config and debian-edu-install. The split made
5106 sense when d-e-install did a lot more, but these days it is just an
5107 inconvenience when we update the debconf preseeding values.
</li
>
5109 <li
>Fix partman-auto to allow us to abort the installation before
5110 touching the disk if the disk is too small. This is
5111 <a href=
"http://bugs.debian.org/
653305">BTS report #
653305</a
> and the
5112 d-i developers are fine with the patch and someone just need to apply
5113 it and upload. After this is done we need to adjust
5114 debian-edu-install to use this new hook.
</li
>
5116 <li
>Adjust to new LTSP framework (boot time config instead of install
5117 time config). LTSP changed its design, and our hooks to install
5118 packages and update the configuration is most likely not going to work
5121 <li
>Consider switching to NBD instead of NFS for LTSP root, to allow
5122 the Kernel to cache files in its normal file cache, possibly speeding
5123 up KDE login on slow networks.
</li
>
5125 <li
>Make it possible to create expired user passwords that need to
5126 change on first login. This is useful when handing out password on
5127 paper, to make sure only the user know the password. This require
5128 fixes to the PAM handling of kdm and gdm.
</li
>
5130 <li
>Make GUI for adding new machines automatically from sitesummary.
5131 The current command line script is not very friendly to people most
5132 familiar with GUIs. This should probably be integrated into GOsa to
5133 have it available where the admin will be looking for it..
</li
>
5135 <li
>We should find way for Nagios to check that the DHCP service
5136 actually is working (as in handling out IP addresses). None of the
5137 Nagios checks I have found so far have been working for me.
</li
>
5139 <li
>We should switch from libpam-nss-ldapd to sssd for all profiles
5140 using LDAP, and not only on for roaming workstations, to have less
5141 packages to configure and consistent setup across all profiles.
</li
>
5143 <li
>We should configure Kerberos to update LDAP and Samba password
5144 when changing password using the Kerberos protocol. The hook was
5145 requested in
<a href=
"http://bugs.debian.org/
588968">BTS report
5146 #
588968</a
> and is now available in Wheezy. We might need to write a
5147 MIT Kerberos plugin in C to get this.
</li
>
5149 <li
>We should clean up the set of applications installed by default.
5152 <li
>reduce the number of chemistry visualisers
</li
>
5153 <li
>consider dropping xpaint
</li
>
5154 <li
>and probably more?
</li
>
5155 </ul
></li
>
5157 <li
>Some hardware need external firmware to work properly. This is
5158 mostly the case for WiFi network cards, but there are some other
5159 examples too. For popular laptops to work out of the box, such
5160 firmware need to be installed from non-free, and we should provide
5161 some GUI to do this. Ubuntu already have this implemented, and we
5162 could consider using their packages. At the moment we have some
5163 command line script to do this (one for the running system, another
5164 for the LTSP chroot).
</li
>
5167 <li
>In Squeeze, we provide KDE, Gnome and LXDE as desktop options. We
5168 should extend the list to Xfce and Sugar, and preferably find a way to
5169 install several and allow the admin or the user to select which one to
5172 <li
>The golearn tool from the goplay package make it easy to check out
5173 interesting educational packages. We should work on the package
5174 tagging in Debian to ensure it represent all the useful educational
5175 packages, and extend the tool to allow it to use packagekit to install
5176 new applications with a simple mouse click.
</li
>
5178 <li
>The Squeeze version got half a exam solution already in place,
5179 with the introduction of iptable based network blocking, but for it to
5180 be a complete exam solution the Squid proxy need to enable
5181 filtering/blocking as well when the exam mode is enabled. We should
5182 implement a way to easily enable this for the schools that want it,
5183 instead of the
"it is documented
" method of today.
</li
>
5185 <li
>A feature used in several schools is the ability for a teacher to
5186 "take over
" the desktop of individual or all computers in the room.
5187 There are at least three implementations,
5188 <a href=
"italc.sourceforge.net/
">italc
</a
>,
5189 <a href=
"http://www.itais.net/help/en/
">controlaula
</a
> og
5190 <a href=
"http://www.epoptes.org/
">epoptes
</a
> and we should pick one of
5191 them and make it trivial to set it up in a school. The challenges is
5192 how to distribute crypto keys and how to group computers in one room
5193 and how to set up which machine/user can control the machines in a
5194 given room.
</li
>
5196 <li
>Tablets and surf boards are getting more and more popular, and we
5197 should look into providing a good solution for integrating these into
5198 the Debian Edu network. Not quite sure how. Perhaps we should
5199 provide a installation profile with better touch screen support for
5200 them, or add some sync services to allow them to exchange
5201 configuration and data with the central server. This should be
5202 investigated.

5225 <p

38 years old and live near Kiel,
5226 Schleswig-Holstein, Germany. I live together with a wonderful partner
5227 (Angela Fuß) and two own children and two bonus children (contributed
5228 by Angela).

5234 becoming an osteopath.
</p

5236 <p
>Starting in
2010 we (Andreas Buchholz, Angela Fuß, Mike Gabriel)
5237 have set up a free software project in the area of Kiel that aims at
5238 introducing free software into schools. The project
's name is
5239 "IT-Zukunft Schule
" (IT future for schools). The project links IT
5240 skills with communication skills.

5245 <p
>While preparing our own customised Linux distribution for
5246 "IT-Zukunft Schule
" we were repeatedly asked if we really wanted to
5247 reinvent the wheel. What schools really need is already available,
5248 people said. From this impulse we started evaluating other Linux
5249 distributions that target being used for school networks.
</p
>
5251 <p
>At the end we short-listed two approaches and compared them: a
5252 commercial Linux distribution developed by a company in Bremen,
5253 Germany, and Skolelinux / Debian Edu. Between
12/
2010 and
03/
2011 we
5254 went to several events and met people being responsible for marketing
5255 and development of either of the distributions. Skolelinux / Debian
5256 Edu was by far much more convincing compared to the other product that
5257 got short-listed beforehand--across the full spectrum. What was most
5258 attractive for me personally: the perspective of collaboration within
5259 the developmental branch of the Debian Edu project itself.
</p
>
5261 <p
>In parallel with this, we talked to many local and not-so-local
5262 people. People teaching at schools, headmasters, politicians, data
5263 protection experts, other IT professionals.
</p
>
5265 <p
>We came to two conclusions:
</p
>
5267 <p
>First, a technical conclusion: What schools need is available in
5268 bits and pieces here and there, and none of the solutions really fit
5269 by
100%. Any school we have seen has a very individual IT setup
5270 whereas most of each school
's requirements could mapped by a standard
5271 IT solution. The requirement to this IT solution is flexibility and
5272 customisability, so that individual adaptations here and there are
5273 possible. In terms of re-distributing and rolling out such a
5274 standardised IT system for schools (a system that is still to some
5275 degree customisable) there is still a lot of work to do here
5276 locally. Debian Edu / Skolelinux has been our choice as the starting
5279 <p
>Second, a holistic conclusion: What schools need does not exist at
5280 all (or we missed it so far). There are several technical solutions
5281 for handling IT at schools that tend to make a good impression. What
5282 has been missing completely here in Germany, though, is the enrolment
5283 of people into using IT and teaching with IT.
"IT-Zukunft Schule
"
5284 tries to provide an approach for this.
</p
>
5286 <p
>Only some schools have some sort of a media concept which explains,
5287 defines and gives guidance on how to use IT in class. Most schools in
5288 Northern Germany do not have an IT service provider, the school
's IT
5289 equipment is managed by one or (if the school is lucky) two (admin)
5290 teachers, most of the workload these admin teachers get done in there
5291 spare time.
</p
>
5293 <p
>We were surprised that only a very few admin teachers were
5294 networked with colleagues from other schools. Basically, every school
5295 here around has its individual approach of providing IT equipment to
5296 teachers and students and the exchange of ideas has been quasi
5297 non-existent until
2010/
2011.
</p
>
5299 <p
>Quite some (non-admin) teachers try to avoid using IT technology in
5300 class as a learning medium completely. Several reasons for this
5301 avoidance do exist.
</p
>
5303 <p
>We discovered that no-one has ever taken a closer look at this
5304 social part of IT management in schools, so far. On our quest journey
5305 for a technical IT solution for schools, we discussed this issue with
5306 several teachers, headmasters, politicians, other IT professionals and
5307 they all confirmed: a holistic approach of considering IT management
5308 at schools, an approach that includes the people in place, will be new
5309 and probably a gain for all.

5311 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5312 Edu?
</strong
></p
>
5314 <p
>There is a list of advantages: international context, openness to
5315 any kind of contributions, do-ocracy policy, the closeness to Debian,
5316 the different installation scenarios possible (from stand-alone
5317 workstation to complex multi-server sites), the transparency within
5318 project communication, honest communication within the group of
5319 developers, etc.

5324 <p

</p
>
5326 <p
>Technically:
<a href=

311188">BTS issue
5327 #
311188</a
>, tricky upgradability of a Debian Edu main server, network
5328 client installations on top of a plain vanilla Debian installation
5329 should become possible sometime in the near future, one could think
5330 about splitting the very complex package debian-edu-config into
5331 several portions (to make it easier for new developers to
5332 contribute).
</p
>
5334 <p
>Another issue I see is that we (as Debian Edu developers) should
5335 find out more about the network of people who do the marketing for
5336 Debian Edu / Skolelinux. There is a very active group in Germany
5337 promoting Skolelinux on the bigger Linux Days within Germany. Are
5338 there other groups like that in other countries? How can we bring
5339 these marketing people together (marketing group A with group B and
5340 all of them with the group of Debian Edu developers)? During the last
5341 meeting of the German Skolelinux group, I got the impression of people
5342 there being rather disconnected from the development department of
5343 Debian Edu / Skolelinux.

5347 <p

5351 more artistic tasks. I run virtual machines in KVM and Virtualbox.

5388 <p

5390 <p
>I am a teacher from Germany, and my subjects are Geography,
5391 Mathematics, and Computer Science (
"Informatik
"). During the past
12
5392 years (since
2000), I have been working for a comprehensive (and soon,
5393 also inclusive) school leading to all kind of general levels, such as
5394 O- or A-level (
"Abitur
"). For quite as long, I
've been taking care of
5395 our computer network.
</p

5397 <p
>Now, in my early
40s, I enjoy the privilege of spending a lot of my
5398 spare time together with my wife, our son (
3 years) and our daughter
5399 (
4 months).
</p
>
5401 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5402 project?
</strong
></p
>
5404 <p
>We had tried different Linux based school servers, when members of
5405 my local Linux User Group (LUG OWL) detected Skolelinux. I remember
5406 very well, being part of a party celebrating the Linux New Media Award
5407 (
"Best Newcomer Distribution
", also nominated: Ubuntu) that was given
5408 to Skolelinux at Linux World Exposition in Frankfurt,
2005 (IIRC). Few
5409 months later, I had the chance to join a developer meeting in Ulsrud
5410 (Oslo) and to hand out the award to Knut Yrvin and others. For more
5411 than
7 years, Skolelinux is part of our schools infrastructure, namely
5412 our main server (tjener), one LTSP (today without thin clients), and
5413 approximately
50 work stations. Most of these have the option to boot a
5414 locally installed Skolelinux image. As a consequence, I joined quite
5415 a few events dealing with free software or Linux, and met many Debian
5416 (Edu) developers. All of them seemed quite nice and competent to me,
5417 one more reason to stick to Skolelinux.
</p

5419 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5420 Edu?
</strong
></p
>
5422 <p
>Debian driven, you are given all the advantages of a community
5423 project including well maintained updates. Once, you are familiar with
5424 the network layout, you can easily roll out an entire educational
5425 computer infrastructure, from just one installation media. As only
5426 free software (FOSS) is used, that supports even elderly hardware,
5427 up-sizing your IT equipment is only limited by space (i.e. available
5428 labs). Especially if you run a LTSP thin client server, your
5429 administration costs tend towards zero.
</p
>
5431 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
5432 Edu?
</strong
></p
>
5434 <p
>While Debian
's stability has loads of advantages for servers, this
5435 might be different in some cases for clients: Schools with unlimited
5436 budget might buy new hardware with components that are not yet
5437 supported by Debian stable, or wish to use more recent versions of
5438 office packages or desktop environments. These schools have the
5439 option to run Debian testing or other distributions - if they have the
5440 capacity to do so. Another issue is that Debian release cycles
5441 include a wide range of changes; therefor a high percentage of human
5442 power seems to be absorbed by just keeping the features of Skolelinux
5443 within the new setting of the version to come. During this process,
5444 the cogs of Debian Edu are getting more and more professional,
5445 i.e. harder to understand for novices.
</p

5447 <p
><strong
>Which free software do you use daily?
</strong
></p
>
5449 <p
>LibreOffice, Wikipedia, Openstreetmap, Iceweasel (Mozilla Firefox),
5450 KMail, Gimp, Inkscape - and of course the Linux Kernel (not only on
5451 PC, Laptop, Mobile, but also our SAT receiver)
</p

5453 <p
><strong
>Which strategy do you believe is the right one to use to
5454 get schools to use free software?
</strong
></p
>
5458 <li
>Support computer science as regular subject in schools to make
5459 people really
"own
" their hardware, to make them understand the
5460 difference between proprietary software products, and free software
5461 developing.
</li
>
5463 <li
>Make budget baskets corresponding: In Germany
's public schools
5464 there are more or less fixed budgets for IT equipment (including
5465 licenses), so schools won
't benefit from any savings here. This
5466 privilege is left to private schools which have consequently a large
5467 share among German Skolelinux schools.
</li
>
5469 <li
>Get free software in the seminars where would-be teachers are
5470 trained. In many cases, teachers
' software customs are respected by
5471 decision makers rather than the expertise of any IT experts.
</li
>
5473 <li
>Don
't limit ourself to free software run natively. Everybody uses
5474 free software or free licenses (for instance Wikipedia), and this
5475 general concept should get expanded to free educational content to be
5476 shared world wide (school books e.g.).
</li
>
5478 <li
>Make clear where ever you can that the market share of free (libre)
5479 office suites is much above
20 p.c. today, and that you pupils don
't
5480 need to know the
"ribbon menu
" in order to get employed.
</li
>
5482 <li
>Talk about the difference between freeware and free software.
</li
>
5484 <li
>Spread free software, or even collections of portable free apps
5485 for USB pen drives. Endorse students to get a legal copy of
5486 Libreoffice rather than accepting them to use illegal serials. And
5487 keep sending documents in ODF formats.

12 år. Men
5512 etter at ryggen sa takk før seg, studerte jeg nettverksadministrasjon
5513 ved Næringsakademiet i Bergen årene
2008-

</p
>
5519 <p
>Mitt mål er å bevisstgjøre musikklærene mulighetene med de frie
5520 programmene som finnes i Skolelinux, blant annet Rosegarden.
</p
>
5522 <p
>Har i mange år drevet med musikk og en av grunnen til at Rosegarden
5523 falt i smak for min del, var fordi denne fungere og ligner mest på
5524 Windows-programmet (cubase) jeg jobbet mye med da jeg i mine yngre
5525 dager var «Windows fanatiker». Ble introdusert til Linux av en kompis
5526 av meg for omtrent
14 år siden, og har bare blitt mer og mer glad i
5527 dette operativsystemet.

5532 havnet jeg i
2007 sammen med Viggo Fedreheim på IKT-avdelingen i

5534 Skolelinuxprosjektet.

>
5536 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p

5538 <p
>Skolelinux er enkelt å holde i drift og masse flotte programmer som
5539 geogebra, ktouch og kgeografi følger med pakken. Man kan ta i bruk
5540 gamle PC-er igjen, slik at skoler med dårlig råd får opp en brukbar
5541 PC-park. PC-er som er ca
6-
9 år gamle fungere tilfredstillende, bare
5542 de har
512 MB RAM eller mer.
</p
>
5544 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
5546 <p
>Ulempene er at noen av de pedagogiske programmene som lærene ønsker
5547 å bruke fungere dårlig med Linux. Mye pga. av at disse programmene
5548 blir ikke laget til Linuxbaserte operativsystemer.
</p
>
5550 <p
>Video- og bilde-redigering har dessverre en del mangler, mange av
5551 programmene har en tendens til og krasje. Det gjelder blant annet
5552 <a href=
"http://www.kdenlive.org/
">kdenlive
</a
> og
5553 <a href=
"http://www.openshotvideo.com/
">openshot
</a
>, for å nevne
5554 noen. De er ikke stabile nok. Når elevene kommer med filmsnutter de
5555 ønsker og jobbe med, så godtar ikke programmene filene, og når elevene
5556 jobber med redigering bare krasjer programmene uten forvarsel. Det er
5557 for vanskelig å få noe som bare fungerer ut av boksen her. Når en elev
5558 plugger inn et videokamera eller fotoapparat så er det alltid noe som
5559 ikke vil fungere. Programmene godtar ikke format, godtar ikke
5560 kameraet, osv., osv. Det er dessverre med på og dra ned en positiv
5561 opplevelse av bruk av fri programvare.
</p
>
5563 <p
>Man må ofte bruke flere en et video redigerings program før og få
5564 fullført en ønsket oppgave.
</p
>
5566 <p
>Eksempel:
</p
>
5568 <p
>Hvis det ene programmet ikke vil ta i mot videofilen klarer et
5569 annet det, men det programmet som klarer det kan ikke gjøre de samme
5570 oppgavene som det programmet som ikke ville ta i mot filen,
5571 Tilsvarende er det med foto, man må bruke flere programmer for å få
5572 et ferdig resultat. Til dags dato har jeg enda ikke funnet et video-
5573 og fotoprogram som kan tilfredstillende fullføre en oppgave.
</p
>
5575 <p
>Så man kan klare og fullføre en oppgave, men i verste fall må man
5576 innom
3-
4 programmer for å få det til. Så jeg har enda ikke til dags
5577 dato sett at et program fungere
100% til alt.
</p
>
5579 <p
>Det programmet jeg har best erfaring til er
5580 <a href=
"http://cinelerra.org/
">cinelerra
</a
>, men dessverre har det
5581 også tendenser og krasje av og til uten grunn.
</p
>
5583 Lydsystemet kan også være et mareritt. Konkret snakker jeg om når du
5584 bruker for eksempel et smartboard, så følger det med USB-lydkort på
5585 disse. Problemet ligger her i at systemet ikke vil velge rett
5586 lydkort, så man må inn med padevchooser for å sette opp PulseAudio
5587 til og velge at USB-lydkortet skal brukes. Det blir for tungvindt for
5588 lærene, de ønsker at ting skal fungere med en gang. (min løsning på
5589 det problemet ble at jeg måtte deaktivere lydkortet som fantes på
5590 maskinen) men da må man bestandig slå på smartboard-tavla.
5592 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
5594 Programmene jeg bruker mest av er: Rosegarden, jack, qsynth, audacity,
5595 k3b, openttd og libreoffice.
5597 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
5598 skoler til å ta i bruk fri programvare?

5600 Jeg tror det må bevisstgjøring av Skolene til, dvs. reklamere høylytt
5601 og fortelle og vise de andre skolene at frie programvarer faktisk
5602 fungere. Jeg trur faktisk mange ikke vet at det finnes frie

>It has been a few busy weeks for me, but I am finally back to
5613 publish another interview with the people behind
5614 <a href=
"http://www.skolelinux.org/
">Debian Edu and Skolelinux
</a
>.
5615 This time it is one of our German developers, who have helped out over the
5616 years to make sure both a lot of major but also a lot of the minor
5617 details get right before release.
5619 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
5621 <p
>My name is Jürgen Leibner, I
'm
49 years old and living in
5622 Bielefeld, a town in northern Germany. I worked nearly
20 years as
5623 certified engineer in the department for plant design and layout of an
5624 international company for machinery and equipment. Since
2011 I
'm a
5625 certified technical writer (tekom e.V.) and doing technical
5626 documentations for a steam turbine manufacturer. From April this year
5627 I will manage the department of technical documentation at a
5628 manufacturer of automation and assembly line engineering.
</p
>
5630 <p
>My first contact with linux was around
1993. Since that time I used
5631 it at work and at home repeatedly but not exclusively as I do now at
5632 home since
2006.
</p
>
5634 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5635 project?
</strong
></p
>
5637 <p
>Once a day in the early year of
2001 when I wanted to fetch my
5638 daughter from primary school, there was a teacher sitting in the
5639 middle of
20 old computers trying to boot them and he failed. I helped
5640 him to get them booting. That was seen by the school director and she
5641 asked me if I would like to manage that the school gets all that old
5642 computers in use. I answered:
"Yes
".
</p
>
5644 <p
>Some weeks later every of the
10 classrooms had one computer
5645 running Windows98. I began to collect old computers and equipment as
5646 gifts and installed the first computer room with a peer-to-peer
5647 network. I did my work at school without being payed in my spare time
5648 and with a lot of fun. About one year later the school was connected
5649 to Internet and a local area network was installed in the school
5650 building. That was the time to have a server and I knew it must be a
5651 Linux server to be able to fulfil all the wishes of the teachers and
5652 being able to do this in a transparent and economic way, without extra
5653 costs for things like licence and software. So I searched for a
5654 school server system running under Linux and I found a couple of
5655 people nearby who founded
'skolelinux.de
'. It was the Skolelinux
5656 prerelease
32 I first tried out for being used at the school. I
5657 managed the IT of that school until the municipal authority took over
5658 the IT management and centralised the services for all schools in
5659 Bielefeld in December of
2006.

>What do you see as the advantages of Skolelinux/Debian
5662 Edu?

5664 <p

'm looking back to the beginning, there were other advantages
5665 for me as today.

>Da jeg googlet etter noe annet kom jeg tilfeldigvis over
5765 <a href=
"http://www.duo.uio.no/sok/work.html?WORKID=
58309">en
5766 hovedfagsoppgave
</a
> ved Universitetet i Oslo som diskuterer verdien
5767 av GPLs fire friheter for brukerne av IT-systemer. Jeg ble fascinert
5768 over det som presenteres der. Her er sammendraget:
</p
>
5770 <p
><blockquote
>
5772 <p
>Motivasjonen til å skrive denne oppgaven er en personlig undring
5773 over hvorfor det primært, og ofte eksklusivt, fokuseres på det
5774 økonomiske aspektet ved utredninger om fri programvare er et godt valg
5775 for det offentlige. Fri og produsenteid programvare bygger på
5776 fundamentalt forskjellige ideologier som kan ha implikasjoner utover
5777 økonomiske kostnader. Kunnskapskulturen som er med på å definere fri
5778 programvare er basert på åpenhet, og er en verdi i seg selv.
</p
>
5780 <p
>Oppgavens tema er programvarelisensen GPL og frihet. GPL-lisensiert
5781 programvare gir visse friheter i forhold til produsenteid
5782 programvare. Mitt spørsmål er om, og eventuelt i hvilken utstrekning,
5783 disse frihetene blir benyttet av ulike brukere og hvordan de
5784 manifesterer seg for disse brukerne. Sentrale spørsmål i oppgaven
5788 <li
>Hvordan fordeles handlekraft gjennom lisensieringen av programvaren?
</li
>
5789 <li
>Hvilke konsekvenser har programvarelisensen for de ulike brukere?
</li
>
5792 <p
>Fri programvare gir blant annet brukeren mulighet til å studere og
5793 modifisere kildekoden. Denne formen for frihet erverves gjennom
5794 kunnskap og krever at brukeren også er en ekspert. Hva skjer med
5795 frihetene til GPL når sluttbrukeren er en annen? Dette diskuteres i
5796 dialog med informantene.
</p
>
5798 <p
>Jeg har i denne oppgaven samlet inn intervjudata fra IKT-ansvarlige
5799 ved grunnskolene i Nittedal kommune, driftsansvarlig og IKT-veilederen
5800 for skolene i kommunen, samt IKT-koordinator for utdanning i Akershus
5801 fylkeskommune og bokmåloversettere av OpenOffice.org. Den empiriske
5802 delen av oppgaven er delt inn i to seksjoner; den første omhandler
5803 operativsystemet Skolelinux, den andre kontorprogrampakken
5804 OpenOffice.org.
</p
>
5806 <p
>Som vi vil se gir GPL lokal frihet og kontroll gjennom omfordeling
5807 av makt fra produsent til bruker. Brukerens makt analyseres gjennom
5808 begrepene brukermedvirkning og handlingsfrihet. Det blir også lagt
5809 vekt på strukturelle forhold rundt bruken av teknologi, og spesielt de
5810 økonomiske begrepene nettverkseksternaliteter, innlåsing og
5811 stiavhengighet. Dette er begreper av spesiell nytte når objektet som
5812 omsettes eller distribueres er et kommunikasjonsprodukt, fordi verdien
5813 til et slikt gode for en potensiell bruker avhenger av antall
5814 eksisterende brukere av godet. I tilknytning til denne problematikken
5815 inneholder oppgaven også en diskusjon rundt åpne standarder og
5818 <p
>Oppgaven konkluderer med at de «fire frihetene» som GPL-lisensen er
5819 laget for å beskytte er av avgjørende betydning for bruken av
5820 OpenOffice.org og Skolelinux, i Akershus fylkeskommune såvel som i
5821 skolene i Nittedal. Distribusjonen av handlekraft er ikke helt
5822 symmetrisk. Det er først og fremst de profesjonelle utviklerne i
5823 Skolelinux som direkte kan nyttiggjøre seg friheten til å endre kode,
5824 mens en sluttbruker som Nittedal kommune nyttiggjør seg den økonomiske
5825 friheten til å kunne distribuere programmene. Det er imidlertid også
5826 slik at ingen aktør klarer seg uten alle disse «frihetene».

>Behind
<a href=
"http://www.skolelinux.org/
">Debian Edu and
5843 Skolelinux
</a
> there are a lot of people doing the hard work of
5844 setting together all the pieces. This time I present to you Andreas
5845 Mundt, who have been part of the technical development team several
5846 years. He was also a key contributor in getting GOsa and Kerberos set
5847 up in the recently released
5848 <a href=

5849 Edu Squeeze
</a

</p
>
5851 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
5853 <p
>My name is Andreas Mundt, I grew up in south Germany. After
5854 studying Physics I spent several years at university doing research in
5855 Quantum Optics. After that I worked some years in an optics company.
5856 Finally I decided to turn over a new leaf in my life and started
5857 teaching
10 to
19 years old kids at school. I teach math, physics,
5858 information technology and science/technology.
</p
>
5860 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5861 project?
</strong
></p
>
5863 <p
>Already before I switched to teaching, I followed the Debian Edu
5864 project because of my interest in education and Debian. Within the
5865 qualification/training period for the teaching, I started
5866 contributing.
</p
>
5868 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5869 Edu?
</strong
></p
>
5871 <p
>The advantages of Debian Edu are the well known name, the
5872 out-of-the-box philosophy and of course the great free software of the
5873 Debian Project!
</p
>
5875 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
5876 Edu?
</strong
></p
>
5878 <p
>As every coin has two sides, the out-of-the-box philosophy has its
5879 downside, too. In my opinion, it is hard to modify and tweak the
5880 setup, if you need or want that. Further more, it is not easily
5881 possible to upgrade the system to a new release. It takes much too
5882 long after a Debian release to prepare the -Edu release, perhaps
5883 because the number of developers working on the core of the code is
5884 rather small and often busy elsewhere.
</p
>
5886 <p
>The
<a href=
"http://wiki.debian.org/DebianLAN
">Debian LAN
</a
>
5887 project might fill the use case of a more flexible system.
</p
>
5889 <p
><strong
>Which free software do you use daily?
</strong
></p
>
5891 <p
>I am only using non-free software if I am forced to and run Debian
5892 on all my machines. For documents I prefer LaTeX and PGF/TikZ, then
5893 mutt and iceweasel for email respectively web browsing. At school I
5894 have Arduino and Fritzing in use for a micro controller project.
</p
>
5896 <p
><strong
>Which strategy do you believe is the right one to use to
5897 get schools to use free software?
</strong
></p
>
5899 <p
>One of the major problems is the vendor lock-in from top to bottom:
5900 Especially in combination with ignorant government employees and
5901 politicians, this works out great for the
"market-leader
". The school
5902 administration here in Baden-Wuerttemberg is occupied by that vendor.
5903 Documents have to be prepared in non-free, proprietary formats. Even
5904 free browsers do not work for the school administration. Publishers
5905 of school books provide software only for proprietary platforms.
</p
>
5907 <p
>To change this, political work is very important. Parts of the
5908 political spectrum have become aware of the problem in the last years.
5909 However it takes quite some time and courageous politicians to
'free
'
5910 the system. There is currently some discussion about
"Open Data
" and
5911 "Free/Open Standards
". I am not sure if all the involved parties have
5912 a clue about the potential of these ideas, and probably only a
5913 fraction takes them seriously. However it might slowly make free
5914 software and the philosophy behind it more known and popular.

5981 <a href=

">Skolelinux Drift AS
</a
> on speeding
5982 up a
<a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>
5983 Lenny installation using LTSP diskless workstations, and in the
5984 process I discovered something very surprising. The reason the KDE
5985 menu was responding slow when using it for the first time, was mostly
5986 due to the way KDE find application icons. I discovered that showing
5987 the Multimedia menu would cause more than
20 000 IP packages to be
5988 passed between the LTSP client and the NFS server. Most of these were
5990 NFS LOOKUP calls, resulting in a NFS3ERR_NOENT response. Because the
5991 ping times between the client and the server were in the range
2-
20
5992 ms, the menus would be very slow. Looking at the strace of kicker in
5993 Lenny (or plasma-desktop i Squeeze - same problem there), I see that
5994 the source of these NFS calls are access(
2) system calls for
5995 non-existing files. KDE can do hundreds of access(
2) calls to find
5996 one icon file. In my example, just finding the mplayer icon required
5997 around
230 access(
2) calls.
</p
>
5999 <p
>The KDE code seem to search for icons using a list of icon
6000 directories, and the list of possible directories is large. In
6001 (almost) each directory, it look for files ending in .png, .svgz, .svg
6002 and .xpm. The result is a very slow KDE menu when /usr/ is NFS
6003 mounted. Showing a single sub menu may result in thousands of NFS
6004 requests. I am not the first one to discover this. I found a
6005 <a href=
"https://bugs.kde.org/show_bug.cgi?id=
211416">KDE bug report
6006 from
2009</a
> about this problem, and it is still unsolved.
</p
>
6008 <p
>My solution to speed up the KDE menu was to create a package
6009 kde-icon-cache that upon installation will look at all .desktop files
6010 used to generate the KDE menu, find their icons, search the icon paths
6011 for the file that KDE will end up finding at run time, and copying the
6012 icon file to /var/lib/kde-icon-cache/. Finally, I add symlinks to
6013 these icon files in one of the first directories where KDE will look
6014 for them. This cut down the number of file accesses required to find
6015 one icon from several hundred to less than
5, and make the KDE menu
6016 almost instantaneous. I
'm not quite sure where to make the package
6017 publicly available, so for now it is only available on request.
</p
>
6019 <p
>The bug report mention that this do not only affect the KDE menu
6020 and icon handling, but also the login process. Not quite sure how to
6021 speed up that part without replacing NFS with for example NBD, and
6022 that is not really an option at the moment.

6084 2002, we used old machines from the city council of Dortmund as thin
6085 clients (LTSP, later Ubuntu/Lessdisks) cause new hardware was out of
6086 reach. At home I
'm using Debian since years and - subscribed to the
6087 Debian news letter - heard from time to time about Skolelinux. About
6088 two years ago I proposed to replace the (somehow undocumented and only
6089 known to me) system at school by a well known Debian based system:
6090 Skolelinux.
</p
>
6092 <p
>Students and teachers appreciated the new system because of a
6093 better look and feel and an enhanced access to local media on thin
6094 clients. The possibility to alter and/or reset passwords using a GUI
6095 was welcomed, too. Being able to do administrative tasks using a GUI
6096 and to easily set up workstations using PXE was of very high value for
6097 the admin teachers.

>What do you see as the advantages of Skolelinux/Debian
6100 Edu?
</strong

6102 <p
>It
's open source, easy to set up, stable and flexible due to it
's
6103 Debian base. It integrates LTSP out-of-the-box. And it is documented!
6104 So it was a perfect choice.
</p
>
6106 <p
>Being open source, there are no license problems and so it
's
6107 possible to point teachers and students to programs like
6108 OpenOffice.org, ViewYourMind (mind mapping) and The Gimp. It
's of
6109 high value to be able to adapt parts of the system to special needs of
6110 a school and to choose where to get support for this.

6117 <p

6119 <p
>At home (Debian Sid with Gnome Desktop): Iceweasel, LibreOffice,
6120 Mutt, Gedit, Document Viewer, Midnight Commander, flpsed (PDF
6121 Annotator). At school (Skolelinux Lenny): Iceweasel, Gedit,
6122 LibreOffice.
</p

6124 <p

>Which strategy do you believe is the right one to use to
6125 get schools to use free software?

6128 that doesn
't seem to work quite well. Now I concentrate on those more

6147 <p
>Det er store forskjeller på skolenes digitale tilstand, viser
6148 undersøkelsen Monitor
2011 som er laget på oppdrag fra
6149 Kunnskapsdepartementet. Dette har ført til debatt om PC-tilgangen i
6150 skolen, og om de med Linux i skolen gjør det bedre bedre eller
6151 dårligere enn snittet i landet.
</p
>
6153 <p
>Nå har vi tallene. Skoler med Linux har
36% større PC-tetthet en
6154 landsgjennomsnittet. På spørsmål hvorfor skoler med Linux har større
6155 PC-tetthet, observerer Paul Reidar Løsnesløkken som er IKT-konsulent i
6156 Nord-Odal:
</p
>
6158 <p
><blockquote
>"Vi erfarer at klienter med Skolelinux har god funksjon
6159 til de er
8 til
10 år gamle. Dette er omtrent dobbelt så lenge som
6160 andre løsninger, og skolene får mer datautstyr for
6161 pengene.
"</blockquote
></p
>
6163 <p
>Undersøkelsen baserer seg på
56 skoler som har gjort det offentlig
6164 at de kjører Skolelinux eller annen Linux-utgave. De kan også ha PC-er
6165 med Windows i skolenettet. Når en sammenligner PC-tetthetene på
6166 skolene i kommunene Flora, Harstad, Kongsvinger, Narvik, Nittedal,
6167 Nord-Odal og Randaberg, er det i snitt
2,
28 elev pr. PC på skolene med
6168 Linux. På landsbasis er det
3.11 elev per PC i grunnskolen, i følge
6169 side
95 i Monitor-rapporten for
2011. Målingen viser dermed
36% større
6170 PC-tetthet i skoler med Linux.

6174 <p
>Skolelinux har til hensikt å gi alle barn full tilgang til
6175 skoleaktuelle dataprogram på sitt eget morsmål. Derfor følger det med
6176 godt over
100 skoleaktuelle programmene laget for læring. De fleste
6177 programmene er oversatt til over
50 språk. Elevene skal også kunne
6178 studere alle sider av dataprogrammene. Derfor følger også kildekode
6179 med. Elever med interesse kan lære av eksperter som har laget
6180 systemet. Dette med enkelt programmering i læreprogram som KTurtle,
6181 til profesjonelle verktøy som Qt Creator eller Java.
</p
>
6183 <p
>Skolelinux er laget for sentralisert drift, der alt teknisk
6184 administrasjon av alle skolene kan gjøres sentralt fra kommunehuset
6185 eller sentralt i en region. F.eks. drifter to-tre personer
70.000
6186 skoledatamaskiner på
200 skoler i delstaten Extremadura i
6187 Spania. Etter velykket bruk av Debian Edu i skolen, legger delstaten
6188 over til Debian på
40.000 datamaskiner i administrasjonen. Det er idag
6189 mange selskap som tilbyr profesjonell støtte til innføring og drift i
6190 Norge og verden.

6227 <description><p
>I serien med intervjuer av folk i
6228 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet, får vi
6229 denne gangen høre fra en IKT-ansvarlig som har brukt Skolelinux i
6230 mange år, og vært storfornøyd med erfaringene så langt.
</p
>
6232 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
6234 <p
>Mitt navn er Roy-Arne Myhre og jeg er
42 år. Jeg er ansatt hos
6235 <a href=
"http://www.sandskole.no/
">Sand skole
</a
> (Balsfjord kommune)
6236 og har stort sett vært det siden
1990. Jeg er IKT ansvarlig ved
6237 skolen i
40% stilling –
10% undervisning – musikk.
</p
>
6239 <p
>Ved skolen er det ca
100 elever og ca
18 lærere +
4 assistenter i
6240 hele og delte stillinger. Alle lærerne har bærbar PC (dessverre med
6241 Win Vista) – assistenter har tilgang til egne. Vi benytter Fronter i
6242 det daglige arbeidet. Vi har ca
90 elevmaskiner som fungerer til
6243 daglig opp mot Linux server (XFCE) som driftes av
6244 <a href=
"http://www.bzz.no/
">BzzWare AS
</a
> via nett. Maskinparken
6245 består kun av brukt utstyr for elevene – og noe av dette begynner å
6246 bli vel gammelt selv som halvtykke klienter.
</p
>
6248 <p
><strong
>Hvordan kom du i kontakt med
6249 Skolelinux-prosjektet?
</strong
></p
>
6251 <p
>Vi kom første gang i kontakt med Skolelinux rundt
1997. Den gang
6252 var det oppstart-disketter i hver maskin, ikke mulighet for lyd og
6253 video, gamle nettverkskort og mye plundring. Vi hadde en ihuga
6254 forelder med som pådriver, forsker og inspirator for hele opplegget.
6255 Selv ante jeg knapt at Skolelinux fantes, men han var av den
6256 utforskende typen, og fikk både meg og skolelederen i trua på at dette
6257 var ting som kunne fungere. Etter dette har det gått gradvis
6258 framover; flere maskiner er hentet inn gjennom bl.a
6259 <a href=
"http://www.greentech.no/
">Greentech
</a
> og utrangert utstyr
6260 fra høgskole / Avinor og private givere. Når maskinene ble for trege
6261 for nye Windows-versjoner, sto vi klare til å putte dem i nettverket
6262 vårt. Dette betyr at vi i dag har
1:
1 dekning av maskiner på
6263 ungdomstrinnet og bedre enn
1:
2 på barnetrinnet. Dette er vi veldig
6264 fornøyd med, og vi kan ikke se for oss hverdagen som ville vært
6265 alternativet ved bruk av Windows med sine lisenser pr. Bruker/maskin.
6266 Da ville vi nok vært tilbake til
1-
2 maskiner pr klasserom med de
6267 negative konsekvenser det ville hatt for undervisningsformene våre. Vi
6268 kan ha en hel klasse i prosjektjobbing eller individuell jobbing
6269 samtidig – vi kan avholde tentamen og eksamen uten
6270 logistikkproblemer.
</p
>
6272 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6274 Hvor skal jeg begynne... Stabiliteten er et nøkkelord - det bare
6275 virker. Har du først fått en server med Skolelinux opp og gå, så må
6276 det en maskinarefeil eller sabotasje til for å stoppe den. Det at man
6277 kan bruke eldre maskiner som normalt sett ville gått på dynga, er også
6278 glimrende - billig for skoler med dårlig økonomi og bra for miljøet
6279 siden vi gjenbruker utstyr i stedet for å skaffe nytt. Vi ville aldri
6280 hatt mulighet til å operere med det maskinantallet vi har pr i dag
6281 hvis det ikke var for Skolelinux - så tilgjengelighet er et annet
6282 nøkkelord. Et tredje moment er sikkerhet og brukertilgang. Alle
6283 brukerer opererer med egne brukernavn og passord, samt egne
6284 brukerområder som kan tilpasses for både enbrukertilgang og for
6285 samarbeid med andre.
6287 Elever har godt av å se at det finnes andre alternativer enn de som
6288 storindustrien selger på lisensbasis - på den måten trenes de opp til
6289 å se flere muligheter og å foreta valg ut fra flere opsjoner.
6291 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6293 <p
>Ulempene med Skolelinux er nok utbredelsen og mangelen på kjennskap
6294 til dette i skolenorge. De som skal ta økonomiske avgjørelser rynker
6295 på nesen og vil gå for det kjente og «sikre» selv om det koster mye
6296 mer. Man får rett og slett litt hetta av å ikke kunne noe – og unngår
6297 dette for enhver pris.
</p
>
6299 <p
>I tillegg er mye av linux-systemet administrert av tekstkommandoer
6300 og er lite intuitiv/visuell for oss som ikke er «inne i»
6301 kildekodene». Så problemet er nok mye godt at de som
6302 utarbeider/drifter Skolelinux ikke helt klarer å sette seg ned på
6303 skoleadministratorens nivå når det gjelder problemer og
6304 utfordringer. Men dette er nok en utfordring alle administratorer
6305 sliter med uansett OS.
</p
>
6307 <p
>Derfor har vi valgt å støtte oss til BzzWare AS for assistanse i
6308 drifta slik at jeg har kunnet konsentrere meg mer om kabling, skifting
6309 av komponenter, veiledning av lærere og elever, vedlikehold av
6310 skrivere og annen daglig drift.
</p
>
6312 <p
>Elevene mestrer Skolelinux helt fint. Så lenge Internett
6313 (Iceweasel) og Libreoffice (Openoffice) fungerer er
90% av
6314 skolehverdagen velfungerende. I tillegg brukes jo en del av den
6315 pedagogiske programpakken bla. i forhold til matematikk og geografi,
6316 men det er såpass mye bra på nett om dagen, så disse programmene er
6317 mer som krydder å regne.
</p
>
6319 <p
>Jeg skulle ønske neste versjon av Skolelinux kunne komme litt
6320 mindre stappet med programmer, for halvparten blir aldri brukt, eller
6321 fungerer ikke uansett. Hva med et pedagogisk panel av lærere/IKT
6322 ansvarlige som kunne sagt: disse programmene skal være standard, så
6323 får resten være slike man kan legge til ved behov – det kan lett bli
6324 en jungel å bevege seg i.
</p
>
6326 <p
>Jeg ønsker meg også en mer grafisk versjon av
6327 <a href=
"http://bzz.no/lwat/trac/trac.cgi
">Lwat
</a
> hvor man kan krysse
6328 ut de som f.eks ikke skal ha internett-tilgang en dag pga
6329 eksamen/tentamen, samt en noe enklere brannmurløsning hvor man kan
6330 stenge for en del (få) sider på en enkel måte. Jeg liker godt
6331 Skolelinux sin ideologi om at filteret skal trenes i hodet på eleven –
6332 men av og til skulle jeg ønske at f.eks Facebook og Youtube kunne vært
6333 koblet vekk en periode for å få bedre utnyttelse av tid og
6334 ressurser. Disse to nettstedene er nok mye av årsaken til at mange
6335 lærere holder igjen databruken noe mer enn man kunne ønske.
</p
>
6337 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
6339 Jeg benytter nesten bare fri programvare til daglig. LibreOffice,
6340 Iceweasel (Firefox), Thunderbird til e-post og Gimp til
6341 bildebehandling. Vi har PHP-Nuke-oppsatt hjemmeside. Det eneste som
6342 jeg ikke har fått helt til enda er videoredigering - her må man vel
6343 innrømme at Mac er hakket over, men da er vi igjen over på å se hva
6344 som egner seg best, og ta valg ut fra det. Folk flest lever i
6345 villfarelsen om at regneark HETER Excel og tekstbehandling HETER
6346 Word. Dette er en misforståelse som jeg bruker mye energi på å
6347 diskutere og
"åpne sinn
" på Microsoft-slaver. Dessverre er det mange
6348 IKT-ansvarlige som også har låst seg på at det eneste saliggjørende er
6349 Bill G sine produkter.
6351 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
6352 skoler til å ta i bruk fri programvare?
</strong
></p
>
6354 <p
>For å komme lenger i utbredelsen av Skolelinux tror jeg det må mer
6355 fram i nasjonale medier, samt komme bedre fram hva økonomien i dette
6356 valget vil være – samt mulighetene. Fri programvare er en berikelse og
6357 gjør oss i stand til å utføre arbeidet i skolen uten å måtte legge
6358 igjen tusener på tusener i Bill Gates lomme.. Få ETT nettsted med
6359 forståelig veiledning av installasjon/oppgradering og ETT forum med
6360 konkrete feilrettinger og problemer, så tror jeg vi kunne kommet et
6361 par skritt framover. Ellers tror jeg bare at ildsjelene må fortsette å
6362 skinne – kanskje flere enn oss følger etter på veien.

6400 i Digi
</a
>. Diskusjonen fikk meg til å bli litt nysgjerrig på om
6401 Linux-skoler har større PC-tettet enn snittet i landet. Grunnlaget
6402 for diskusjonen har vært undersøkelsen
6403 <a href=
"https://iktsenteret.no/ressurser/monitor-
2011-skolens-digitale-tilstand
">Monitor
6404 2011</a
>, som bruker informasjon fra
6405 <a href=
"https://www.wis.no/gsi
">Grunnskolens Informasjonssystem
</a
>
6406 (GSI). GSI-data kan lastes ned fra web og jeg lastet ned en Excel-fil
6407 (intet åpen standard-valg tilgjengelig) med navn på alle skoler,
6408 hvilke kommune de befinner seg i og hvor mange elever pr. elev-PC de
6409 har rapportert inn. For å få en ide om svaret trenger jeg deretter å
6410 vite hvilke skoler i landet som bruker Linux, slik at jeg kan slå dem
6411 opp i GSI og finne ut hvor stor PC-tetthet de har.
</p
>
6413 <p
>Jeg vet om skoler i Balsfjord, Flora, Harstad, Kongsvinger, Narvik,
6414 Nittedal, Nord-Odal, Randaberg og Sunndal som bruker Skolelinux eller
6415 andre Linux-varianter. Jeg tror det er flere enn de
56 skolene jeg
6416 har klart å identifisere de siste dagene, men har ikke klart å få det
6417 bekreftet med offentlige kilder.
</p

6419 <p
>Monitor
2011-rapporteres side
95 forteller at det
"ifølge GSI
6420 (
20120-
2011) er det
3,
11 elever per datamaskin når vi tar med alle
6421 grunnskoler (

". For de
56 Linux-skolene jeg har klart å
6422 koble mot informasjon i GSI er det
2,
28 elever per elevdatamaskin,
6423 hvilket betyr at det er
36% høyere PC-tetthet på Linux-skoler enn
6424 landsgjennomsnittet. Linux-skolen med høyest tettet blant de jeg har
6425 notert -skole er Flora ungdomsskule i Flora kommune med
0.82 elev
6426 pr. PC (
482 elever,

>Who are you, and how do you spend your days?
</strong
></p
>
6455 <p
>I teach ICT part time at the Rudolf Steiner School in Kings
6456 Langley, near London, UK. Previously I worked as a technical
6457 author/trainer while my children attended the school, and I also
6458 contributed to the Schoolforge UK community with the aim of
6459 encouraging UK schools to adopt free/open source software. Five or six
6460 years ago we had about
50 schools interested in some way, but we
6461 weren
't able to convert many of them into sustainable
6462 installations.
</p
>
6464 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
6465 project?
</strong
></p
>
6467 <p
>Skolelinux had two representatives at an early Edubuntu meeting in
6468 London which I attended. However at that time our school network had
6469 just been installed using CentOS, LTSP
4 and GNOME. When LTSP
5 came
6470 along we switched to Edubuntu thin client servers so now we have a
6471 mixed environment which includes Windows PCs and student laptops, as
6472 well as their MacBooks and iPads. However, the proprietary systems
6473 have always been rather problematic, and we never built a GUI for the
6474 LDAP server, so when I discovered Skolelinux is configured for all
6475 these things we decided to try it.
</p
>
6477 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
6478 Edu?
</strong
></p
>
6480 <p
>By far the biggest advantage is the Debian Edu community. Apart
6481 from that I have always believed in the same
"sustainable computing
"
6482 goals that Skolelinux is built on: installing Linux on computers which
6483 would otherwise be thrown away, to provide a reliable, secure and
6484 low-cost IT environment for schools. From my own experience I know
6485 that a part-time person can teach and manage a network of about
25
6486 Linux computers, but it would take much more of my time if we had
6487 proprietary software everywhere.

6489 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
6490 Edu?
</strong

6492 <p
>As a newcomer I
'm just finding out who
's who in the community and
6493 how you
're organised, and what your procedures are for dealing with
6494 various things such as editing manual pages and so-on. The only
6495 English language mailing list seems to be for developers as well as
6496 users, so my inbox needs heavy pruning each day!
</p
>
6498 <p
><strong
>Which free software do you use daily?
</strong
></p
>
6500 <p
>Besides the software already mentioned at school we use Samba,
6501 OpenLDAP, CUPS, Nagios and Dansguardian for the network, and on the
6502 desktops we have LibreOffice, Firefox, GIMP and Inkscape. At home I
6503 use Ubuntu and an Android
4 eePad Transformer (but I
'm not sure if
6504 that counts...)
</p
>
6506 <p
><strong
>Which strategy do you believe is the right one to use to
6507 get schools to use free software?
</strong
></p
>
6509 <p
>That
's a tough question! For very many years UK schools installed
6510 and taught only proprietary software, so that at the highest levels
6511 the notion of
"computer
" means simply
"proprietary office
6512 applications
". However, schools today are experiencing budget
6513 constraints, and many are having to think hard about upgrading Windows
6514 XP. At the same time, we have students showing teachers how to use
6515 iPads, MacBooks and Android, so the choice of operating system is no
6516 longer quite so automatic. What is more, our government at last
6517 realised that we need people with programming skills, so they
're
6518 putting coding back in the curriculum! And it
's encouraging that the
6519 first
10,
000 Raspberry Pi units sold out in
2 hours.
</p
>
6521 <p
>I don
't really know what strategy is going to get UK schools to use
6522 free software, but building an active community of Skolelinux/Debian
6523 Edu users in this country has to be part of it.

>Documentation in Debian Edu is provided in several languages, and
6533 it is important to make it both easy to contribute and to keep the
6534 translated versions in sync. To do this we have come up with what we
6535 believe is a very efficient work flow.
</p
>
6539 <li
>The documentation is written in a
6540 <a href=
"http://moinmo.in
">moinmoin wiki
</a
> (see for example
6541 <a href=
"http://wiki.debian.org/DebianEdu/Documentation/Squeeze
">the
6542 Squeeze release manual
</a
>) with support for exporting the content as
6543 docbook XML.
</li
>
6545 <li
>This docbook document is given to po4a to extract a gettext style
6546 .pot file with the content, which in turn is used to create .po files
6547 with the translated text.
</li
>
6549 <li
>The .po files are given to translators, and they can always tell
6550 which part of the original wiki document is new or changed. They can
6551 use their normal translation tools like lokalize or poedit to write
6552 the translation. There is even a system in place to handle translated
6555 <li
>The translated .po files are combined with the original docbook
6556 XML document using po4a to create a translated docbook document.
</li
>
6558 <li
>The final step is to use all the generated docbook files and
6559 create PDF and HTML version of the original and translated documents.
</li
>
6563 <p
>This setup work very well, but have a few issues. The biggest
6564 issue is that
<a href=
"http://moinmo.in/DocBook
">the docbook support
6565 we use in moinmoin
</a
> is not actively maintained. The docbook
6566 support is also buggy, and our build system contain workarounds to
6567 make sure the generated docbook is usable despite these bugs.

6626 <p
>Jeg hørte om det først når jeg jobbet i Redpill Linpro. Men jeg
6627 har også en datter som går på en friskole, som også bruker Skolelinux.
6628 Som kjent har ikke friskoler de samme økonomiske rammebetingelsene som
6629 offentlige skoler, så for dem var det det absolutt beste alternativet.
6630 De anser også Skolelinux som et stabilt system, som bare går og går (i
6631 motsetning til det lille Windows-baserte nettverket de har på
6632 admin-siden).

6636 <p
>Sentralisert drift av tynne og diskløse arbeidsstasjoner. Således
6637 lydløse og raskere arbeidsstasjoner som er bedre i klasserommet.
6638 Lengre levetid på PC
'er. Store besparelser på maskinvare og drift. Og
6639 så klart fjerning av alle lisenskostnader. Personlig synes jeg også at
6640 mange av programmene er bedre enn alternativene. Men dette er ofte en
6641 smakssak og avhengig om man må ha det man er vant til fra før.

6643 <p

>Hva er ulempene med Skolelinux slik du ser det?

6645 <p
>For lite kjentskap til løsningen. Noen ganger for dårlig
6646 kompatibilitet med arbeidsstasjoners/bærbare maskiner sine
6647 nettverksdrivere eller skjermkort. Men dette løser vi i skolene ved
6648 standardisering. Ellers er det få, om nesten ingen, av de kjente
6649 maskinvare / infrastruktur leverandørene til fylkes- / kommuner som
6650 tilbyr denne plattformen. Skal dette endre seg så må kommunene selv
6651 sette slike krav til leverandørene.
</p

6653 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
6655 <p
>Har brukt OpenOffice.org siden starten (
2001 ?), Kun Linux på
6656 desktop siden
2005. Bruker i dag Kubuntu, Libreoffice og ymse annet
6657 programvare til ulik kontorbruk som er lett å installere / teste via
6658 alle programarkivene som finnes.

6660 <p

>Hvilken strategi tror du er den rette å bruke for å få
6661 skoler til å ta i bruk fri programvare?
</strong
></p
>
6663 <p
>Fortsette å presentere flere av de gode eksemplene hvor Debian Edu
6664 / Skolelinux brukes i kommuner og enkeltskoler. Vi må få bedre frem
6665 at det er mulig tilknytte både Windows og Mac klienter på denne
6666 plattformen (selv om det vil øke driftskostnadene). Dette gjøres
6667 mange steder. Spesielt er det mange lærere som ønsker å bruke
6668 Windows/Mac-bærbare, gjerne som sin private PC også. Det er også mulig
6669 for kommunen å integrere med Active Directory i stedet for OpenLDAP
6670 som kommer med ut av boksen (selv om også dette øker kostnadene).
6671 Dette vil muligens bidra til å fjerne noe motstand hos noen
6672 potensielle brukere / driftpersonell for å ta i bruk noe
6673 nytt. Fremveksten av mobile brukere og nettbrett går i vår favør.
6674 Brukerne blir kjent og vant til flere nye operativsystemer /
6675 brukergrensesnitt. Så utviklerfellesskapet bør jobbe videre med å
6676 integrere flere nye klienttyper, som ultra lav-kostklienter og
6677 nettbrett (blant annet fri programvare-alternativet

<a href=

">the
6709 interview series
</a
> conducted by Raphael, I started a Norwegian
6710 interview series with people involved in the Debian Edu / Skolelinux
6711 community. This was so popular that I believe it is time to move to a
6712 more international audience.
</p
>
6714 <p
>While
<a href=
"http://www.skolelinux.org/
">Debian Edu and
6715 Skolelinux
</a
> originated in France and Norway, and have most users in
6716 Europe, there are users all around the globe. One of those far away
6717 from me is Nigel Barker, a long time Debian Edu system administrator
6718 and contributor. It is thanks to him that Debian Edu is adjusted to
6719 work out of the box in Japan. I got him to answer a few questions,
6720 and am happy to share the response with you. :)
6723 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
6725 <p
>My name is Nigel Barker, and I am British. I am married to Yumiko,
6726 and we have three lovely children, aged
15,
14 and
4(!) I am the IT
6727 Coordinator at Hiroshima International School, Japan. I am also a
6728 teacher, and in fact I spend most of my day teaching Mathematics,
6729 Science, IT, and Chemistry. I was originally a Chemistry teacher, but
6730 I have always had an interest in computers. Another teacher teaches
6731 primary school IT, but apart from that I am the only computer person,
6732 so that means I am the network manager, technician and webmaster,
6733 also, and I help people with their computer problems. I teach python
6734 to beginners in an after-school club. I am way too busy, so I really
6735 appreciate the simplicity of Skolelinux.
</p
>
6737 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
6738 project?
</strong
></p
>
6740 <p
>In around
2004 or
5 I discovered the ltsp project, and set up a
6741 server in the IT lab. I wanted some way to connect it to our central
6742 samba server, which I was also quite poor at configuring. I discovered
6743 Edubuntu when it came out, but it didn
't really improve my setup. I
6744 did various desperate searches for things like
"school Linux server
"
6745 and ended up in a document called
"Drift
" something or other. Reading
6746 there it became clear that Skolelinux was going to solve all my
6747 problems in one go. I was very excited, but apprehensive, because my
6748 previous attempts to install Debian had ended in failure (I used
6749 Mandrake for everything - ltsp, samba, apache, mail, ns...). I
6750 downloaded a beta version, had some problems, so subscribed to the
6751 Debian Edu list for help. I have remained subscribed ever since, and
6752 my school has run a Skolelinux network since Sarge.

6755 Edu?

6757 <p
>For me the integrated setup. This is not just the server, or the
6758 workstation, or the ltsp. Its all of them, and its all configured
6759 ready to go. I read somewhere in the early documentation that it is
6760 designed to be setup and managed by the Maths or Science teacher, who
6761 doesn
't necessarily know much about computers, in a small Norwegian
6762 school. That describes me perfectly if you replace Norway with

6768 <p
>The desktop is fairly plain. If you compare it with Edubuntu, who
6769 have fun themes for children, or with distributions such as Mint, who
6770 make the desktop beautiful. They create a good impression on people
6771 who don
't need to understand how to use any of it, but who might be
6772 important to the school. School administrators or directors, for
6773 instance, or parents. Even kids. Debian itself usually has ugly
6774 default theme settings. It was my dream a few years back that some
6775 kind of integration would allow Edubuntu to do the desktop stuff and
6776 Debian Edu the servers, but now I realise how impossible that is. A
6777 second disadvantage is that if something goes wrong, or you need to
6778 customise something, then suddenly the level of expertise required
6779 multiplies. For example, backup wasn
't working properly in Lenny. It
6780 took me ages to learn how to set up my own server to do rsync backups.
6781 I am afraid of anything to do with ldap, but perhaps Gosa will

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

6786 <p
>Nowadays I only use Debian on my personal computers. I have one for
6787 studio work (I play guitar and write songs), running AV Linux
6788 (customised Debian) a netbook running Squeeze, and a bigger laptop
6789 still running Skolelinux Lenny workstation. I have a Tjener in my
6790 house, that
's very useful for the family photos and music. At school
6791 the students only use Skolelinux. (Some teachers and the office still
6792 have windows). So that means we only use free software all day every
6793 day. Open office, The GIMP, Firefox/Iceweasel, VLC and Audacity are
6794 installed on every computer in school, irrespective of OS. We also
6795 have Koha on Debian for the library, and Apache, Moodle, b2evolution
6796 and Etomite on Debian for the www. The firewall is Untangle.

><strong
>Which strategy do you believe is the right one to use to
6799 get schools to use free software?
</strong
></p
>
6801 <p
>Current trends are in our favour. Open source is big in industry,
6802 and ordinary people have heard of it. The spread of Android and the
6803 popularity of Apple have helped to weaken the impression that you have
6804 to have Microsoft on everything. People complain to me much less about
6805 file formats and Word than they did
5 years ago. The Edu aspect is
6806 also a selling point. This is all customised for schools. Where is the
6807 Windows-edu, or the Mac-edu? But of course the main attraction is
6808 budget.The trick is to convince people that the quality is not
6809 compromised when you stop paying and use free software instead. That
6810 is one reason why I say the desktop experience is a weakness. People

>Many years ago, the
<a href=
"http://www.skolelinux.org/
">Skolelinux
6859 / Debian Edu project
</a
> initiated a student project to create a tool
6860 for making stop motion movies. The proposal came from a teacher
6861 needing such tool on Skolelinux. The project, called
"stopmotion
",
6862 was manned by two extraordinary students and won a school award and a
6863 national aware with this great project. The project was initiated and
6864 mentored by Herman Robak, and manned by the students Bjørn Erik Nilsen
6865 and Fredrik Berg Kjølstad. They got in touch with people at Aardman
6866 Animation studio and received feedback on how professionals would like
6867 such stopmotion tool to work, and the end result was and is used by
6868 animators around the globe. But as is usual after studying, both got
6869 jobs and went elsewhere, and did not have time to properly tend to the
6870 project, and it has been lingering for a few years now. Until last
6873 <p
>Last year some of the users got together with Herman, and moved the
6874 project to Sourceforge and in effect restarted the project under a new
6876 <a href=
"http://sourceforge.net/projects/linuxstopmotion/
">linuxstopmotion
</a
>.
6877 The name change was done to make it possible to find the project using
6878 Internet search engines (try to search for
'stopmotion
' to see what I
6879 mean). I
've been following
6880 <a href=
"https://lists.sourceforge.net/lists/listinfo/linuxstopmotion-community
">the
6881 mailing list
</a

>Knut Yrvin her. Jobber i Nokia med å fremme rammeverket Qt og QML
6960 med tilhørende utviklerverktøy. Rollen er som leder av
6961 friprog-samfunn. I fjor var jeg med å legge om utviklingen av Qt til
6962 åpen forvaltning. På den måten kan alle som bidrar til Qt gjøre det
6963 på like vilkår. Nå er det
6964 <a href=

5-%E2%
80%
93-a-look-back-at-the-numbers/
">over
6965 1000 utviklere
</a
> som bidrar til Qt. Med overgangen til åpen
6966 forvaltning er utviklingen av Qt mer åpen enn Linux-kjernen.
</p
>
6968 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
6970 <p
>Jeg var en av initiativtagerne til Skolelinux i
2001. Skolene slet
6971 med både utstyr og Internett-tilgang. De klarte ikke å møte
6972 forventningene til data i skolen. Driften av PC-ene var uholdbar. Som
6973 regel hadde rektor pekt ut en ivrig lærer til å passe på PC-ene,
6974 gjerne naturfaglæreren. Mange lærere jobbet mye ubetalt overtid for å
6975 vedlikeholde
30-
40 datamaskiner på hver sin skole. Med
300 elever og
6976 lærere som brukere, blir det fort mye mer arbeid enn de
4-
8 timene de
6977 kunne bruke på PC-drift. Skolene hadde kun en femtedel av
6978 IT-budsjettet som ble brukt på PC-ene i rådhuset.
</p
>
6980 <p
>Vi erfarte at skolene hadde mye datautstyr som stod ubrukt. Skolene
6981 manglet penger til Microsoft-lisenser. Selv med solide skolerabatter,
6982 kostet Microsoft-lisensene gjerne like mye som PC-ene i seg selv over
6983 en periode på
5-
6 år.
</p
>
6985 <p
>Viktigheten av språklig mangfold og pedagogiske programmer var også
6986 viktig for oss. Vi oversatte mange skoleaktuelle programmer til
6987 nynorsk, nordsamisk og bokmål. Dette lenge før andre tok denne
6988 oppgaven seriøst. Allerede etter ett år hadde vi etablert et helt
6989 arsenal av skoleaktuelle programmer på nynorsk, bokmål og
6990 nordsamisk. Vi spredde vår ide om språklig mangfold til de andre frie
6991 prosjekter internasjonalt. Resultatene ser vi i mange land. Det er de
6992 frie programmene som kommer på brukernes morsmål. Det er en av flere
6993 gode grunner til at fri programvare som LibreOffice, VLC, KDE og
6994 Firefox konkurrerer ut godseid programvare mange steder i verden.
</p
>
6996 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6998 <p
>Fordelene er at Skolelinux tilbyr over
100 skoleaktuelle programmer
6999 på de norske språkene, uten ett øre i lisenskostnader. Systemet gir
7000 enormt lave driftskostnader med diskløse arbeidsstasjoner og bærbare
7001 med roaming. Skolelinux krever også mindre av maskinvaren.
</p
>
7003 <p
>Man kan fint kjøre systemet med
512 MB RAM på en bærbar PC sammen
7004 med en nettvideo i nettleseren og en presentasjon med
7005 LibreOffice. Konkurrerende system krever fort
2 GB RAM for å få til
7006 noe tilsvarende uten at det går ufattelig tregt. Skal man gjøre noe
7007 nyttig, krever konkurrentene til Linux mye større harddisk. Skoler har
7008 rapportert at de fort har fått
50% flere nye maskiner om de velger
7009 Linux. Dette i tillegg til de årlige besparelsene ved å unngå
7010 lisensbetaling til godseid programvare.
</p
>
7012 <p
>De lave driftskostnadene gjør at delstater i Europa har titusener
7013 av datamaskiner med Skolelinux i skolen. F.eks. er det under ti
7014 personer som drifter
70.000 PC-systemer i skolene i Extremadura i
7015 Spania. Det er slett ikke uvanlig at norske kommuner har
1500-
2000
7016 datamaskiner med Skolelinux. Driften tar ett årsverk. Slår flere
7017 kommuner seg sammen, kan de få samme sentraliserte stordriftsfordeler
7018 som delstater i Tyskland og Spania. Delstater som kjører Skolelinux
7019 på alle skolene. Bare noen få personer sentraldrifter titusenvis av
7022 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7024 <p
>Den største ulempen for Skolelinux er motstand mot Linux fra
7025 IT-sjefer i det offentlige. Dette er ledere som holder innlegg som
7026 snytt ut av evangelist-håndboka til Microsoft. Dette gjøres i ett
7027 arbeidsmarked med stor vekst i etterspørselen etter Linux-fagfolk i
7028 privat sektor. Etterspørselen har økt mer enn noe annet tekniske yrke
7029 siste tiåret. Åtte av ti ledere vil ansette Linux-fagfolk i
2012,
7030 rapporterer jobbnettstedet Dice.com på oppdrag av Linux
7031 Foundation.
</p
>
7033 <p
>Det mangler
16.000 ingeniører og IKT-fagfolk i Norge rapporterte
7034 arbeids- og velferdsetaten NAV. Linux-fagfolk kan velge svært
7035 interessante jobber med alt fra apps på ledende mobilsystem laget med
7036 Linux, sky- tjenester eller web-applikasjoner. De raskest voksende
7037 teknologiselskapene i verden er ute etter Linux-fagfolk. Det være seg
7038 Amazon, Google, Facebook og IBM for å nevne noen. Linux er kritisk
7039 for å sikre veksten i markedet. Det sier seg selv at lønningene og
7040 jobbmulighetene er bedre enn for andre tekniske yrker.
</p
>
7042 <p
>Skal man lage apps for mobilen, smart-TV-en eller
7043 underholdningssystemet i bilen eller på flyet, er det Linux som
7044 gjelder. Med en slik konkurranse om Linux-kompetansen, kombinert med
7045 motstanden mot Linux hos mange IT-sjefer i offentlig sektor, så
7046 hindrer kommunene rekruttering av flere Linux- fagfolk. Skolene blir
7047 tvunget til å velge dyrere og mindre komplette IT-system. De har
7048 blitt hengende igjen slik IT var på begynnelsen av
2000- tallet. Dette
7049 fordi IT-ledere ikke har tilpasset seg markedet det siste tiåret.
</p
>
7051 <p
>Når det er sagt, er Skolelinux svært enkelt å lære seg også for de
7052 som ikke kan. Det viser alle lærerne som drifter systemet for
7053 hundrevis og tusenvis av systemer. Det meste er på plass rett ut av
7054 boksen. I tillegg er det solid med dokumentasjon med god hjelp på
7055 nettet. Det er mange kommuner som har ansatt en lærer som først lærte
7056 Skolelinux på sin skole, for så å drifte alle PC-ene i kommunen med
7057 Skolelinux. Det kan fort være snakk om
1000-
3000 datamaskiner på
10-
15
7058 skoler som sentraldriftes med en stilling. Står man ordentlig fast,
7059 kan man også kjøpe profesjonell hjelp fra selskap som støtter
7060 Skolelinux. Det er flere slike selskap i Norge og i utlandet.

7064 <p
>Qt SDK, LibreOffice, Firefox, VLC og KDE-skrivebordet. Dette på et
7065 Debian-basert GNU/Linux-system. Jeg bruker også noen morsomme
7066 3D-spill. Idag kan jeg velge mellom over
30.000 Linux-programmer. Det
7067 finnes ikke tid i livet å undersøke alle valgmulighetene. Derfor er
7068 det bra med Skolelinux i skolen, da utvalget av programmer er
7069 begrenset til hva som er aktuelt i skolefagene.
</p

7071 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
7072 skoler til å ta i bruk fri programvare?
</strong
></p

7074 <p
>Vi må selge hele Skolelinux forhåndsinstallert på maskinvare i hele
7075 pakker med
50-
100-
1000 PC-klienter med servere. Dette kan selges til
7076 enkeltskoler eller hele kommuner. Pakken må inneholde tjenermaskiner,
7077 svært rimelige diskløse arbeidsstasjoner, nettbrett med Plasma Active,
7078 og bærbare med roaming. Alt er godt testet med Debian. I et slikt
7079 anbud er det mulig å legge til sentraliserte drifts- og
7080 støttetjenester.
</p
>
7082 <p
>Man bør også selge sky-tjenester som læreadministrative systemet
7083 Moodle og driftsovervåking. I tillegg så bør man slenge seg på med
7084 presentasjoner de gangene LibreOffice og andre friprog-produkter
7085 selges til kommuner.

7125 norske utgaven av OpenOffice.org. Arbeidet har hele tiden vært

>Vi må få leverandører av pedagogisk programvare med på laget, men
7160 også utvikle vår egen tilpasset det norske markedet. Det er også
7161 mulig å involvere utdanningssektoren direkte i arbeidet, for eksempel
7162 gjennom studentprosjekter der elevene selv er med å utforme
7163 programvare direkte eller indirekte gjennom aktive bidrag. Dette gjør
7164 ikke bare samarbeidet tettere, men fokuset på standarder og friheten
7165 til å velge sin egen løsning vil kanskje stimulere interessen for
7166 framtidig deltakelse i bransjen. Vi som driver med fri og åpen
7167 programvare ønsker oss ikke rene konsumenter, men tenkende og
7168 selvstendige individer som kan være med å skape sin egen fremtid.

7177 <description><p
>New in the Squeeze version of
7178 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> is the
7179 ability for clients to automatically configure their proxy settings
7180 based on their environment. We want all systems on the client to use
7181 the WPAD based proxy definition fetched from
<tt
>http://wpad/wpad.dat
</tt
>, to
7182 allow sites to control the proxy setting from a central place and make
7183 sure clients do not have hard coded proxy settings. The schools can
7184 change the global proxy setting by editing
7185 <tt
>tjener:/etc/debian-edu/www/wpad.dat
</tt
> and the change propagate
7186 to all Debian Edu clients in the network.
</p
>
7188 <p
>The problem is that some systems do not understand the WPAD system.
7189 In other words, how do one get from a WPAD file like this (this is a
7190 simple one, they can run arbitrary code):
</p
>
7192 <blockquote
><pre
>
7193 function FindProxyForURL(url, host)
7195 if (!isResolvable(host) ||
7196 isPlainHostName(host) ||
7197 dnsDomainIs(host,
".intern
"))
7198 return
"DIRECT
";
7200 return
"PROXY webcache:
3128; DIRECT
";
7202 </pre
></blockquote
>
7204 <p
>to a proxy setting in the process environment looking like this:
</p
>
7206 <blockquote
><pre
>
7207 http_proxy=http://webcache:
3128/
7208 ftp_proxy=http://webcache:
3128/
7209 </pre
></blockquote
>
7211 <p
>To do this conversion I developed a perl script that will execute
7212 the javascript fragment in the WPAD file and return the proxy that
7214 <tt
><a href=
"http://www.debian.org/
">http://www.debian.org/
</a
></tt
>,
7215 and insert this extracted proxy URL in
<tt
>/etc/environment
</tt
> and
7216 <tt
>/etc/apt/apt.conf
</tt
>. The perl script wpad-extract work just
7217 fine in Squeeze, but in Wheezy the library it need to run the
7218 javascript code is
<a href=
"http://bugs.debian.org/
631045">no longer
7219 able to build
</a
> because the C library it depended on is now a C++
7220 library. I hope someone find a solution to that problem before Wheezy
7221 is frozen. An alternative would be for us to rewrite wpad-extract to
7222 use some other javascript library currently working in Wheezy, but no
7223 known alternative is known at the moment.
</p
>
7225 <p
>This automatic proxy system allow the roaming workstation (aka
7226 laptop) setup in Debian Edu/Squeeze to use the proxy when the laptop
7227 is connected to the backbone network in a Debian Edu setup, and to
7228 automatically use any proxy present and announced using the WPAD
7229 feature when it is connected to other networks. And if no proxy is
7230 announced, direct connections will be used instead.
</p
>
7232 <p
>Silently using a proxy announced on the network might be a privacy
7233 or security problem. But those controlling DHCP and DNS on a network
7234 could just as easily set up a transparent proxy, and force all HTTP
7235 and FTP connections to use a proxy anyway, so I consider that
7236 distinction to be academic. If you are afraid of using the wrong
7237 proxy, you should avoid connecting to the network in question in the
7238 first place. In Debian Edu, the proxy setup is updated using dhcp and
7239 ifupdown hooks, to make sure the configuration is updated every time
7240 the network setup changes.
</p
>
7242 <p
>The WPAD system is documented in a
7243 <a href=

01">IETF

7267 være med som oversetter. Jeg kom med på en utviklersamling og
7268 prosjektet var da helt i starten. Det var spennende å være med mens
7269 prosjektet vokste til og utviklet seg.
</p

7271 <p
>Jeg har «alltid» vært språkinteressert og hadde nettopp startet med
7272 Linux og tror jeg tenkte det passet å bidra. Var også glad for å få
7273 en Debian-distribusjon, og ville gjerne bruke den selv. Til å begynne
7274 med brukte jeg først Mandrake og så Debian. Og siden jeg oppdaget at
7275 det ikke var noen mulighet for å bruke den som enkeltstående i lang
7276 tid, så gikk jeg etterhvert over til Kubuntu

7278 <p

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

7280 <p
>Løsningen er forholdsvis lett å sette opp, gratis, fri programvare
7281 og gjør det mulig å gjenbruke eldre maskiner. Det fine med Debian er
7282 at det er stabilt og har en veldig stor mengde programmer. Jeg liker
7283 også apt. :-) Jeg liker også friheten ved Linux og muligheten til å
7284 delta og forme sin egen datahverdag.

7288 <p
>Skolelinux er for lite kjent og for sent ute med å gi ut nye
7289 versjoner.
</p
>
7291 <p
>Da jeg selv i hovedsak bruker Kubuntu, så kan jeg egentlig ikke
7292 svare så detaljert rundt ulempene med Skolelinux. Hovedårsaken til at
7293 jeg bruker Kubuntu er nok at da vi begynte med det mener jeg det ikke
7294 var noen annen løsning. «Vandrende arbeidsstasjon» mener jeg ikke
7295 fantes da. Dessuten ville jeg ha siste versjon, da den KDE-versjonen
7296 som var i Skolelinux den gangen var en god del enklere (tror det var
7297 KDE
2) var dårligere i mine øyne enn versjon
3.

7316 er ansvarlige for å vedlikeholde og bruke datamaskinene. Flest mulig
7317 bør være med på å holde det (sosialt) vedlike, kjenne og støtte
7318 prinsippene. Som enkeltmannsprosjekt blir det lett veldig sårbart,
7319 særlig når (Skole)linux ennå i stor grad er en motkultur og ikke noe
7320 en stor nok andel av beslutningstakere, brukere osv kjenner til og
7323 <p

7324 oppdatert, minimere antall feil, ha en god kontakt med brukerne og
7325 attraktivt og spennende programmer. Beholde alt som er bra og ha det
7326 tilgjengelig samtidig som man tilbyr det nyeste og rareste for de som

>Since the Lenny version of
7337 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>, a
7338 feature to save power have been included. It is as simple as it is
7339 practical: Shut down unused clients at night, and turn them on again
7340 in the morning. This is done using the
7341 <a href=
"http://packages.qa.debian.org/s/shutdown-at-night.html
">shutdown-at-night
</a
> Debian package.
</p
>
7343 <p
>To enable this feature on a client, the machine need to be added to
7344 the netgroup shutdown-at-night-hosts. For Debian Edu, this is done in
7345 LDAP, and once this is in place, the machine in question will check
7346 every hour from
16:
00 until
06:
00 to see if the machine is unused, and
7347 shut it down if it is. If the hardware in question is supported by
7349 <a href=
"http://packages.qa.debian.org/n/nvram-wakeup.html
">nvram-wakeup
</a
>
7350 package, the BIOS is told to turn the machine back on around
07:
00 +-
7351 10 minutes. If this isn
't working, one can configure wake-on-lan to
7352 try to turn on the client. The wake-on-lan option is only documented
7353 and not enabled by default in Debian Edu.
</p
>
7355 <p
>It is important to not turn all machines on at once, as this can
7356 blow a fuse if several computers are connected to the same fuse like
7357 the common setup for a classroom. The nvram-wakeup method only work
7358 for machines with a functioning hardware/BIOS clock. I
've seen old
7359 machines where the BIOS battery were dead and the hardware clock were
7360 starting from
0 (or was it
1990?) every boot. If you have one of
7361 those, you have to turn on the computer manually.
</p
>
7363 <p
>The shutdown-at-night package is completely self contained, and can
7364 also be used outside the Debian Edu environment. For those without a
7365 central LDAP server with netgroups, one can instead touch the file
7366 <tt
>/etc/shutdown-at-night/shutdown-at-night
</tt
> to enable it.
7367 Perhaps you too can use it to save some power?

</p

7391 <li
>It is now possible to change the pre-configured IP subnet from
7392 10.0.0.0/
8 to something else by using the subnet-change tool after
7393 the installation.
</li

7395 <li
>Too full partitions are now automatically extended on the Main
7396 Server, based on the rules specified in /etc/fsautoresizetab.
</li
>
7398 <li
>The CUPS queues are now automatically flushed every night, and all
7399 disabled queues are restarted every hour. This should cut down on
7400 the amount of manual administration needed for printers.
</li
>
7402 <li
>The set of initial users have been changed. Now a personal user
7403 for the local system administrator is created during installation
7404 instead of the previously created localadmin and super-admin users,
7405 and this user is granted administrative privileges using group
7406 membership. This reduces the number of passwords one need to keep
7407 up to date on the system.

7411 <p
>The new main server seem to work so well that I am testing it as my
7412 private DNS/LDAP/Kerberos/PXE/LTSP server at home. I will use it look
7413 for issues we could fix to polish Debian Edu even further before the
7414 final Squeeze release is published.

>With some computer hardware, one need non-free firmware blobs.
7430 This is the sad fact of todays computers. In the next version of
7431 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> based
7432 on Squeeze, we provide several scripts and modifications to make
7433 firmware blobs easier to handle. The common use case I run into is a
7434 laptop with a wireless network card requiring non-free firmware to
7435 work, but there are other use cases as well.
</p
>
7437 <p
>First and foremost, Debian Edu provide ISO images for DVD and CD
7438 with all firmware packages in the Debian sections main and non-free
7439 included, to ensure debian-installer find and can install all of them
7440 during installation. This take care firmware for network devices used
7441 by the installer when installing from from local media. But for
7442 example multimedia devices are not activated in the installer and are
7443 not taken care of by this.
</p
>
7445 <p
>For non-network devices, we provide the script
7446 <tt
>/usr/share/debian-edu-config/tools/auto-addfirmware
</tt
> which
7447 search through the
<tt
>dmesg
</tt
> output for drivers requesting extra
7448 firmware. The firmware file name is looked up in the Contents-ARCH.gz
7449 file available in the package repository, and the packages providing
7450 the requested firmware file(s) is installed. I have proposed to do
7451 something similar in debian-installer (BTS report
7452 <a href=
"http://bugs.debian.org/
655507">#
655507</a
>), to allow PXE
7453 installs of Debian to handle firmware installation better. Run the
7454 script as root from the command line to fetch and install the needed
7455 firmware packages.
</p
>
7457 <p
>Debian Edu provide PXE installation of Debian out of the box, and
7458 because some machines need firmware to get their network cards
7459 working, the installation initrd some times need extra firmware
7460 included to be able to install at all. To fill the PXE installation
7461 initrd with extra firmware, the
7462 <tt
>/usr/share/debian-edu-config/tools/pxe-addfirmware
</tt
> script is
7463 provided. Again, just run it as root on the command line to fill the
7464 PXE initrd with firmware packages.
</p
>
7466 <p
>Last, some LTSP clients might also need firmware to get their
7467 network cards working. For this,
7468 <tt
>/usr/share/debian-edu-config/tools/ltsp-addfirmware
</tt
> is
7469 provided to update the LTSP initrd with firmware blobs. It is used
7470 the same way as the other firmware related tools.
</p
>
7472 <p
>At the moment, we do not run any of these during installation. We
7473 do not know if this is acceptable for the local administrator to use
7474 non-free software, and it is their choice.

7532 <description><p
>The next version of
<a href=
"http://www.skolelinux.org/
">Debian Edu
7533 / Skolelinux
</a
> will include a new tool
7534 <tt
>sitesummary2ldapdhcp
</tt
>, which can be used to quickly set up all
7535 the computers in a school without much manual labour. Here is a short
7536 summary on how to use it to set up a new school.
</p
>
7538 <p
>First, install a combined Main Server and Thin Client Server as the
7539 central server in the network. Next, PXE boot all the client machines
7540 as thin clients and wait
5 minutes after the last client booted to
7541 allow the clients to report their existence to the central server. When
7542 this is done, log on to the central server and run
7543 <tt
>sitesummary2ldapdhcp -a
</tt
> in the
<tt
>konsole
</tt
> to use the
7544 collected information to generate system objects in LDAP. The output
7545 will look similar to this:
</p
>
7547 <p
><blockquote
><pre
>
7548 % sitesummary2ldapdhcp -a

7552 Enter password if you want to activate these changes, and ^c to abort.
7554 Connecting to LDAP as cn=admin,ou=ldap-access,dc=skole,dc=skolelinux,dc=no
7555 enter password: *******
7557 </pre
></blockquote
></p
>
7559 <p
>After providing the LDAP administrative password (the same as the
7560 root password set during installation), the LDAP database will be
7561 populated with system objects for each PXE booted machine with
7562 automatically generated names. The final step to set up the school is
7563 then to log into
<a href=
"https://oss.gonicus.de/labs/gosa/
">GOsa
</a
>,
7564 the web based user, group and system administration system to change
7565 system names, add systems to the correct host groups and finally
7566 enable DHCP and DNS for the systems. All clients that should be used
7567 as diskless workstations should be added to the workstation-hosts
7568 group. After this is done, all computers can be booted again via PXE
7569 and get their assigned names and group based configuration
7570 automatically.
</p
>
7572 <p
>We plan to release beta3 with the updated version of this feature
7573 enabled this weekend. You might want to give it a try.
</p
>
7575 <p
>Update
2012-
01-
28: When calling sitesummary2ldapdhcp to add new
7576 hosts, one need to add the option -a. I forgot to mention this in my
7577 original text, and have added it to the text now.

7586 <description><p
>I serien med intervjuer av folk i
7587 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet, har jeg nå
7588 lyktes med å få tak i en skolemann som ikke er aktiv med utviklingen,
7589 men likevel har vært med nesten siden starten av prosjektet. Jeg
7590 ønsker derfor velkommen til Paul Reidar Løsnesløkken, en mann med
7591 mange års erfaring i bruk av Skolelinux.
</p
>
7593 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
7595 <p
>Jeg driftet tidligere IKT løsningen for skolene i
7596 <a href=
"http://www.nord-odal.kommune.no/
">Nord-Odal
</a
>. I dag er jeg
7597 IKT-konsulent for hele kommunen og samarbeider med
7598 <a href=
"http://www.hedmarken-ikt.no/
">Hedmark-IKT
</a
> for best mulig
7599 tjenester til kommunen. Jeg har bakgrunn som elektronikkreparatør og
7600 grunnskolelærer og har tatt en del fag innen IKT, i hovedsak
7601 driftsfag. IKT i Nord-Odal kommune blir i dag driftet av Hedmark IKT
7602 som er et samarbeid mellom Løten, Stange, Grue, Hamar, Kongsvinger og
7603 Nord-Odal. Jeg er fortsatt
"IKT-personen
" på skolene i kommunen og
7604 følger opp og gjør enkelte mindre endringer der.
</p
>
7606 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
7608 <p
>Kommunen satset på Skolelinux i
2004. Jeg var ikke med i
7609 beslutningsprosessen den gang, men ble likevel med fra starten når
7610 dette ble levert.
</p
>
7612 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7614 <p
>Fordelene med Skolelinux er rask oppstart, sentral drift av
7615 klientene, klienter som jobber raskt og effektivt, bedre
7616 funksjonalitet på eldre utstyr og en ganske god programpakke med fri
7617 programvare som følger med. Løsningen med halvtykke klienter gjør at
7618 prosessering skjer lokalt med alltid ferske maskiner.
</p
>
7620 <p
>Skolelinux kan fungere godt på gammelt utstyr, men det er klart at
7621 utstyr også blir for gammelt selv for Skolelinux. I forbindelese med
7622 at vi nylig fikk nye servere og ny installasjon kastet jeg ut ca
60
7623 klienter som fortsatt var i drift etter at de var kjøpt godt brukt i
7624 2004. Noe var rundt
15 år gammelt, men var fortsatt i bruk. Noen
7625 klaget på at det nå gikk veldig tregt på en del pedagogiske nettsider
7626 med flash o.l. Det er fullt forståelig.
</p
>
7628 <p
>Jeg fikk nylig et spørsmål fra ungdomsskolens rektor om jeg kunne
7629 legge inn
<a href=
"http://freemind.sourceforge.net/
">FreeMind
</a
>, et
7630 tankekartprogram , på skolens elev-Windowsmaskiner. Lærerne hadde
7631 vært på kurs og ville ta dette i bruk. Skolen har ca halvparten av
7632 elevmaskinene på bærbare Windowsmaskiner. Da kunne jeg fortelle at
7633 dette programmet allerede lå inne på den nye Skolelinuxløsningen
7634 som nettopp var satt i drift, klart til bruk.
</p
>
7636 <p
>Vi har de bærbare maskinene på ungdomsskolen i domene med
7637 Skolelinux. Dette fungerer også meget bra nå. Elevene får opp en
7638 midlertidig windowsprofil når de logger på. Denne profilen slettes
7639 etter at de logger av, noe som medfører rene profiler hver gang de
7640 starter opp en maskin. De må lagre i sin Skolelinprofil, noe som
7641 medfører at de får tak i sine filer uavhengig av om de starter en
7642 Windowsmaskin eller en Skolelinuxklient. Det er mye mindre trafikk i
7643 det trådløse nettet etter at ikke hele profiler blir lastet opp til de
7644 enkelte Windowsmaskinene og tilbake når man avslutter. Jeg vet ikke om
7645 dette er standardoppsett i Skolelinux, men slik er vårt oppsett
7648 <p
>Vi har i flere år satt opp vår løsning slik at skriverkøer slettes
7649 og skrivere startes hver natt. Hyggelig å høre at dette nå skal bli
7650 en standard i Skolelinuxløsningen. Dette har vært en god hjelp for
7653 <p
>Elevene er lite opptatt av om de jobber på en Skolelinux eller en
7654 Windowsmaskin bare de har de programmene de trenger og at det virker
7655 når det skal brukes. Vi kjører mest mulig de samme programmene på
7656 Windows som i Skolelinux, som f.eks Audacity og LibreOffice.
</p
>
7658 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7660 <p
>Lærere bruker hos oss Windows. Dette fordi de da selv har mer
7661 kontroll over sin maskin, kan bruke den overalt, og kan legge inn
7662 programmer selv når de trenger noe i forhold til kurs o.l de er
7663 på. Jeg tror lærernes selvstendighet her gjør dem tryggere på IKT-bruk
7664 generelt. Det at de av og til får opp advarsler og lignende gjør også
7665 at de må tenke igjennom og spørre om ting rundt datasikkerhet.
</p
>
7667 <p
>Det er en del programmer vi bruker som ikke finnes for Linux. Mest
7668 brukt er nok Photostory3 som brukes i mange sammenhenger, særlig på
7669 ungdomsskolen, bl.a. til å lage herbarier (plantesamling) . Dette
7670 finnes gratis for Windows, men er ikke fri programvare. Vi er opptatt
7671 av at programmer elevene bruker på skolen også kan brukes gratis
7672 hjemme. Det er også en del programmer som brukes til spesielle elever
7673 som bare går i Windows. Det er viktig med fokus på funksjoner og ikke
7674 på hvilket OS man bruker.
</p
>
7676 <p
>For oss er det kombinasjonen mellom Skolelinux og Windows som gir
7677 oss en god og hel løsning. Skolelinux er best der de er gode.
</p
>
7679 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
7681 <p
>Selv er det LibreOffice jeg bruker til daglig. Jeg bruker selv en
7682 Windowsmaskin. Jeg har benyttet en del fri programvare i forbindelse
7683 med sjekking av trafikk i nettverk, slik som Wireshark, men dette er
7684 jo ikke aktuelt for skolene. Jeg er generelt glad i programmer som
7685 fungerer på både Linux og Windows og gjerne MAC.
</p
>
7687 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
7688 skoler til å ta i bruk fri programvare?
</strong
></p
>
7690 <p
>Det er viktig at det benyttes programmer som elevene også kan ta i
7691 bruk hjemme. Det skal da være enkelt, lovlig og gratis for
7692 elevene. Da er jeg ikke lenger veldig opptatt av om det kalles
"fri
7693 programvare
". For skolene tror jeg
"gratis
" og
"funksjonelt
" er bedre
7694 begreper enn
"fri
" i forhold til programmer. De fleste skiller nok
7695 ikke mellom
"fri
" og
"gratis
". Det er nå svært mange elever som
7696 benytter OpenOffice eller LibreOffice som sin primære kontorpakke

>During christmas, I have been working getting the next version of
7753 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> ready
7754 for release. The initial problem I looked at was particularly
7755 interesting.
</p
>
7757 <P
>The installer would hang at the end when it was doing it
7758 post-installation configuration, and whatevery I did to try to find
7759 the cause and fix it always worked while I tested it, but never when I
7760 integrated it into the installer and ran the installation from
7761 scratch. I would try to restart processes, close file descriptors,
7762 remove or create files, and the installer would always unblock and
7763 wrap up its tasks.
</p
>
7765 <p
>Eventually the cause was found. The kernel was simply running out
7766 of entropy, causing the Kerberos setup to hang waiting for more.
7767 Pressing keys was adding entropy to the kernel, and thus all my tries
7768 to fix the problem worked not because what I was typing to fix it, but
7769 because I was typing.
</P
>
7771 <p
>The fix I implemented was to add a background process looking at
7772 the level of entropy in the kernel (by checking
7773 /proc/sys/kernel/random/entropy_avail), and if it was too small, the
7774 installer will flush the kernel file buffers and do
'find /
' to
7775 generate some disk IO. Disk IO generate entropy in the kernel, and is
7776 one of the few things that can be initated from within the system to
7777 generate entropy.

>Etter en lang pause er det klart for neste mann ut i min serie med
7794 <a href=

">Skolelinux
</a

7796 Denne gangen har jeg besøk av et avtroppende styremedlem i
7797 <a href=

">FRISK
</a

7798 som har vært aktiv i Linux-miljøet i Bergen siden
90-tallet.

7800 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
7802 <p
>Jeg heter Peter Hansteen, og jobber til daglig som seniorkonsulent
7803 i EDB ErgoGroup i Bergen. I praksis betyr det systemadministrasjon på
7804 Unix (primært Solaris, men en viss komponent av Linux). Men Solaris
7805 er for meg et relativt nytt bekjentskap, hovedplattformen min har
7806 generelt vært OpenBSD og til dels FreeBSD.

7808 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
7810 <p
>Jeg husker ikke helt alle detaljene mer ;) - men jeg tror det var
7811 gjennom news-gruppen no.it.os.unix.linux.diverse, efn-listen og
7812 etterhvert også BLUG-miljøet her i Bergen. Vi hadde et par
7813 Skolelinux-sentrerte BLUG-møter for noen år siden, og det har vært et
7814 par Skolelinux-utviklersamlinger her.
</p

7816 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7818 <p
>Jeg bruker dessverre ikke Skolelinux daglig. Men slik jeg kjenner
7819 prosjektet har det vært i stand til å ta opp i seg det beste av fri
7820 programvare i mange kategorier, så fra et sysadmin-perspektiv ser det
7821 ut som en svært behagelig sak. For brukerne er det vel både en fordel
7822 og en ulempe at det ikke er Windows. Men vi håper at fordelene med et
7823 fritt system etterhvert vil bli åpenbare for både elever, lærekrefter
7824 og foreldre.
</p
>
7826 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7828 <p
>Vel, ulempen er vel først og fremst at andre aktører med mer
7829 kapitalmuskel har klart å etablere seg som det både lærere og foreldre
7830 føler seg trygge på, selv om det etter mitt hode ikke er noen grunn
7831 til å være spesielt trygg på de kommersielle alternativene.
</p
>
7833 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
7835 <p
>Når jeg får bestemme helt selv, bruker jeg kun fri programvare. Da
7836 helst med vekt på ting som kjører greit på OpenBSD. Hjemme er det
7837 OpenBSD, Ubuntu eller FreeBSD vi bruker. På skrivebordet er det en
7838 avveining mellom Gnome, KDE eller hva-det-nå-heter som er
7839 standardvalget i Ubuntu, ellers er det de kjente tingene som
7840 LibreOffice, Emacs, mplayer. På server er det selvfølgelig Apache,
7841 for overvåking både OpenNMS og Nagios (det bare ble sånn, og
7842 forskjellige siter). Jeg skriver til tider om slikt jeg holder på med
7844 <a href=
"http://bsdly.blogspot.com
">http://bsdly.blogspot.com
</a
>.
</p
>
7846 <p
>Men vi må nevne at selv vi har en Microsoft-ting som vi slår på når
7847 vi av en eller annen grunn må. Det betyr igjen vanligvis når en
7848 mobiltelefon eller en annen lukket elektronisk dings krever kontakt
7849 via en slik for å få oppdateringene sine.
</p
>
7851 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
7852 skoler til å ta i bruk fri programvare?
</strong
></p
>
7854 <p
>Hadde vi hatt det rette svaret på det spørsmålet, så hadde vi
7855 gjerne hatt Skolelinux som førstevalg på alle skoler ;)
</p
>
7857 <p
>Men jeg tror vi må legge vekt på flere forskjellige ting. En helt
7858 sentral sak er å fokusere på fri programvare og åpne standarder som de
7859 demokratiske verdiene de faktisk er. Det har kanskje kommet litt for
7860 mye i bakgrunnen i forhold til strevet etter å lage det mest mulig
7861 'brukervennlige
' systemet. Det er en tung vei å gå, så det er
7862 forståelig at freenix-aktivister heller velger å skrive kode og annet
7863 som er mer lystbetont. Mer praktisk tror jeg vi må gjøre i alle fall
7864 to ting: For det første sørge for å fortsette med å levere det best
7865 mulige frie produktet, slik at det er lett å både komme i gang og
7866 holde systemene i daglig drift, og for det andre
2) spore opp mulige
7867 aktivister der de finnes, via lokale brukergrupper, sosiale medier
7868 eller annet og sørge for at de fortsetter å være aktive. Mer og
7869 mindre uformelle treff kan være nyttig i tillegg til de mer
7870 organiserte møtene med foredrag, konferanser og utviklersamlinger.

7885 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
7887 <p
>Mitt navn er Frode Jemtland, og jeg jobber i Hedmark IKT, som er et
7888 driftsselskap for Grue, Hamar, Kongsvinger, Løten, Nord-Odal og Stange
7889 kommuner. Her er jeg leder for avdelingen Løsninger og Arkitektur. Vi
7890 har i hovedansvar for servere, infrastruktur og løsninger som
7893 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
7895 <p
>Jobbet i IBM fra
2000, og da spesielt med Linux. Dette var da et av
7896 de mest tydelige linux prosjektene i Norge, og her ønsket jeg å
7897 bidra. Var aktivt med i prosjektet i
4-
5 år.
</p
>
7899 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7901 <p
>Fordelene slik jeg ser det er den sentraliserte driftmodellen, og
7902 alle de vel gjennomtenkte løsningene som er inkludert i denne
7903 løsningen. Samtidig er det basert på en stabil, og godt kjent
7904 plattform. Dette vil si at man har en løsning som skal være mye
7905 tilgjengelig, og hvor det er relativt enkelt å få tak i personer som
7906 kan mye om den grunnleggende plattformen.
</p
>
7908 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7910 <p
>De største utfordringene med en løsningen er at den er intensiv på f.eks
7911 nettverk. I seg selv ikke et problem for en enkelt skole, men skal løsningen
7912 kjøres i større skala, med sentraliserte servere, så gir dette noen
7913 utfordringer.
</p
>
7915 <p
>Utifra hva jeg har sett på større installasjoner så er det ikke så
7916 enkelt å skjønne, hva som bør gjøres for at den skal skaleres opp, og
7917 da ta godt vare på alle sider av dette, ikke bare mer server å fordele
7918 last/trykk, men hvordan også beholde robustheten og fleksibiliteten i
7919 løsningen.
</p
>
7921 <p
>En annen utfordring er at stadig flere produkter som skal brukes i
7922 skoleløsningen ikke er laget til å kunne brukes i en
7923 skolelinuxløsning. Det blir derfor fort mye skreddersøm i de
7924 forskjellige installasjonene, for å få diverse pedagogiske programmer,
7925 webløsninger, smartboards, m.m. til å fungere. Man er også en for
7926 liten kundebase til at leverandørene ønsker å gjøre noe med
7927 utfordringen. Problemet overlates til oss.
</p
>
7929 <p
>Det er også en kontinuerlig utfordring rundt problemet med å holde
7930 programvare på stabile versjoner, kontra å få ny funksjonalitet. Dette
7931 er jo en konflikt mellom oss som ønsker å drifte en stabil, og
7932 kostnadseffektiv løsning, mot sluttbrukerne som ønsker seg funksjoner
7933 det er vant med fra andre løsninger, eller som de må ha for at et
7934 eller annet nytt produkt skal fungere i løsningen. Dette er en
7935 utfordring også for andre plattformer.
</p
>
7937 <p
>En siste utfordring som ikke har noe med løsningen å gjøre, men med
7938 det omkringliggende miljøet denne skal kjøre i, er at de enhetene som
7939 skal drifte dataløsninger for kommuner og fylkeskommuner begynner å
7940 profesjonaliseres, og er da avhengig av å ha standard løsninger for å
7941 drifte store brukermasser. MS er selvsagt klar over dette, og har jo
7942 nå flere områder de begynner å bli veldig dominerende på. Den største,
7943 og mest problematiske er katalogtjenesten. Man får snart ikke tak i
7944 større løsninger som ikke krever en AD. Når man da har store enheter
7945 som drifter både kommunalt ansatte og skoler, så vil det være et
7946 stordriftargument å standardisere på en katalog tjeneste, og da har
7947 man ikke noe valg. Her er alle slike driftsenheter for små til å få
7948 gjort om på dette. Her burde konkurransemyndighetene kommet på
7949 banen. Men konkurransetilsynet i USA griper sjeldent (og ikke før det
7950 har gått veldig lang tid) inn i monopolsituasjoner så lenge
7951 monopolisten er et amerikansk firma, så da har vel ikke andre
7952 myndigheter så mye de skulle ha sagt....
</p
>
7954 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
7956 <p
>Privat kjører jeg Debian på alle mine datamaskiner. Det gjør jeg
7957 også på min jobbmaskin. Vi har også
15-
20 linux servere av typene
7958 SuSE, Debian, Redhat, CentOS m.m. Jeg bruker derfor mye fri
7959 programvare. Av enkelt programmer kan sikkert masse nevnes. Hvis vi
7960 skal begrense oss til daglig, så må jeg si: OpenOffice, Firefox,
7961 Kontact, Kopete, Amarok,
7962 <a href=
"http://gramps-project.org/
">Gramps
</a
>, Kate, ssh, bash,
7963 rsync, backuppc m.m.
</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
>Det er et godt spørsmål, som jeg har lurt på selv.
</p
>
7970 <p
>Argumentene som ofte har vært brukt om at ting koster mindre holder
7971 ikke mål når man ser på hva som faktisk koster penger. Det er de
7972 ansatte som er en kostnadsdriver. Det vil si at hvis man har et system
7973 som den ansatte kan, så vil en kostnad på dette systemet kunne
7974 forsvares ganske mye ved at den ansatte gjør dette raskere og
7975 effektivt. Også uten å måtte eventuelt leie inn folk.
</p
>
7977 <p
>Jeg syns det er viktigere å fokusere på prinsippet med å velge fri
7978 programvare, men det er også et felt hvor man fort møter lite
7979 forståelse blant de ansatte i skolen.
</p
>
7981 <p
>Her må nok strategien fortsette å være at de sentrale myndighetene
7982 må sende tydelige signaler for hva de ønsker at offentlige enheter
7983 skal gjøre. Det var mye positivt på gang ang. dette for et par år
7984 siden. Både med eNorge og eKommune planene, men dette syns jeg har
7985 stoppet opp. En del av dette kan jo kanskje være usikkerheten som
7986 etter hvert har blitt, når man har sett kompleksiteten i de
7987 prosjektene som har blitt igangsatt. Det har også blitt noe usikkerhet
7988 i markedet ref. Sun, Oracle, Novell, Microsoft m.m. Samtidig har jo
7989 også de proprietære programleverandørene sørget for å endre sine
7990 lisenser slik at man uansett ikke slipper unna kostnaden til deres
7991 produkter, selv om man skulle velge alternativer. Da er det økonomiske
7992 argumentet, som jeg nevnte tidligere, spilt ganske godt ut over
7993 sidelinjen.

8016 <p
>Hmm, det er lenge siden, så det er nesten så jeg ikke husker. Jeg
8017 hadde vel hørt om prosjektet i media før en gjeng i Trondheim startet
8018 opp SPIST, Skolelinux-prosjektet i Sør-Trøndelag, hvor vi hjalp noen
8019 skoler i nærområdet med å installere Skolelinux og finne brukt
8020 IT-utstyr til disse. Det var moro å gjøre noe praktisk for å spre
8021 Skolelinux, og å se hvor fort gjort det var å sette opp utrangerte
8022 klientmaskiner og få disse opp som tynnklienter på helt nye datasaler
8023 på skolene, kun med kostnaden til servere.
</p

8025 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?

8027 <p
>Det er et system spesielt skreddersydd for drift av et stort antall
8028 klienter mot servere, og da spesielt i henhold til skolers behov. Det
8029 er enkelt og billig å installere og drifte, og det trenger ikke ny
8030 maskinvare for god ytelse.

>Hardwarestøtten kunne vært bedre og i enda større grad
8035 installerbart rett ut av boksen. Distribusjonen har til tider hatt
8036 litt gammel programvare pga. at den følger Debian sine utgivelser.
8037 Kanskje man skulle vurdert en versjon basert på Ubuntu eller andre
8038 distribusjoner i tillegg?

8044 Chromium, Pidgin, Digikam, OpenOffice, Wireshark, git og irssi.
8045 Telefonen min er en Android, og der bruker jeg programmene K-
9 Mail,
8046 OI Shopping list, Shuffle, ZXing, OI Notepad og ADW Desktop. På jobb
8047 bruker jeg JBoss, Eclipse, uCLinux for Blackfin, RCF-CPP, Qt, Maven,

>En bør fokusere på totalkostnader inkludert driftsbehov,
8054 fleksibilitet, åpenhet og ikke låsing til en leverandør framfor sparte
8055 lisenskostnader, samt programvarens kvalitet og fortrinn, og at den
8056 fritt kan brukes på et ubegrenset antall PC-er, også hjemme hos
8057 elevene. En bør også forbedre den fri programvaren ved testing,
8058 bugrapportering og kodebidrag om man kan, og ikke anbefale programvare
8059 uten at man har forsikret seg at den har tilstrekkelig kvalitet,
8060 ellers kan man lett oppnå det motsatte. Tror en bør selge inn
8061 konseptet til fylkes-/statsnivå, kanskje med bidrag til
8062 utviklingsarbeid fra disse som alle landets skoler kan få glede

>Mine bloggposter om Linux i skolene i Norge førte til at inspektør
8073 og ildsjel på Harestad skole tok kontakt og fortalte at de bruker
8074 Linux på sin skole, og lurte på om de kunne bidra til å gjøre
8075 fordelene kjent. Riktig nok bruker de ikke
8076 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
> på denne skolen,
8077 men jeg synes dette er en god anledning til å gjøre flere fasetter
8078 rundt Linux-økosystemet kjent, og tok et lite intervju.

>Mitt navn er Odin Hetland Nøsen og er en
70-modell. Jeg er bosatt i
8083 Stavanger og jobber nå på
9. året som undervisninginspektør på
8084 Harestad skole i Randaberg kommune (nabokommune til Stavanger).

8088 <p
>I
2002 begynte daværende IKT-ansvarlige og jeg et arbeid på skolen
8089 med å gå over fra Win98 til... noe annet. Vi testet en rekke
8090 forskjellige løsninger, deriblant Skolelinux, men endte opp med
8091 RedHat. Skolelinux var den gang ikke modent for det vi ville ha. Jeg
8092 har siden fulgt jevnlig med på hva skolelinux holder på med, men har
8093 hele tiden vært bedre fornøyd med vår egen
"standardiserte
" løsning på
8094 RedHat/CentOS og Fedora. Vi snuser for tiden på Ubuntu som løsning på
8095 klientsiden.
</p
>
8097 <p
>I dag har vi på skolen vår en større linux-løsning med
400 klienter
8098 som kjører en blanding av LTSP (tynnklient) og DRBL (tykk klient uten
8099 harddisk) med en masse tjenere på serverrommet. Vi drifter hele
8100 sulamitten selv med webtjener, eposttjener, webmail, filtjenere,
8101 virtuelle tjenere osv. Og IT-ansvarlig har en
80% stilling som
8102 IT-ansvarlig - og så er han KoH-lærer i de resterende
20% :-)

</a

</p
>
8107 <p
>For å ta brodden av frykten for at ildsjeler gjør skolen sårbar om
8108 ildsjelene falle fra, har jeg forsikret kommunen og skolesjefen i
8109 Randaberg om at det finnes godt kommersielle tjenester vi kan benytte
8110 oss av - om det skulle bli nødvendig. Vi er tre stykker i kommunen som
8111 nå har
<strong
>god
</strong
> linux-kompetanse ift. å drifte et større
8112 system. IT-avdelingen i kommunen vil ikke ta på oss med ildtang -
8113 selv om vi nok har større IT-kompetanse mot linux enn det de selv har
8114 mot windows (de kjøper en
<strong
>masse
</strong
> konsulenttjenester
8115 fra ErgoGroup).
</p
>
8117 <p
>I kvantitet er Harestad og Grødem skole tilsammen et større
8118 IT-system enn resten av Randaberg kommune + Kvitsøy og Rennesøy, som
8119 kommunen også har driftsansvar for. Vi har som sagt rundt
800
8120 maskiner, mens kommunen med sitt driftsansvar har ansvar for rundt
500
8121 maskiner. Det er selvfølgelig litt forskjell i hvor kritiske
8122 tjenestene våre er, men det gir allikevel et litt rart bilde når
8123 IT-avdelingen overhode ikke er interessert i å snakke med oss om
8124 hvordan vi gjør ting :-)

><strong

</strong
></p
>
8128 <p
>Fra linux-perspektivet (ikke bare Skolelinux) er det en fordel av
8129 systemet er basert på fri programvare - og dermed fritt i ordets mange
8130 betydninger. Det er alt vi trenger: stabilt, relativt enkelt å drifte
8131 (tross alt - et større windowssystem er ikke enkelt å holde live det
8132 heller), rimelig i innkjøp og drift, og sist, men ikke minst, det er
8133 moderne for sluttbruker! Linux, i sine mange varianter,
8134 <strong
>ser
</strong
> nytt ut, fordi det hele tiden blir
8135 oppdatert. Derfor lever systemet opp til hvordan elever forventer at
8136 et moderne GUI skal være (i motsetning til WinXP :-).
</p
>
8138 <p
>Vi var veldig pragmatiske da vi begynte med linux i skolen. Det var
8139 billig, det fungerte og kunne bruke alle de gamle windows-maskinene
8140 som
"nye
" tynne klienter. I dag er vi mer bevisste fri
8141 programvare-tilhengere. Vi har oppdaget hva det er - og vi liker
8144 <p
>En av de
<strong
>store
</strong
> fordelene med fri programvare er at
8145 vi kan installere tjenester vi ønsker å tilby brukerne våre - uten å
8146 måtte tenke på om vi har råd til lisensene (fordi det er ingen). Alt
8147 vi setter i produksjon er ut i fra brukernes behov og vår kapasitet
8148 til å drifte dem. Vi skreddersyr tjenestene etter behovet og dermed
8149 trenger vi ikke ende opp med å kjøpe en pakke der vi egentlig bare var
8150 interessert i en liten del av den.

>Ikke all pedagogisk programvare er tilgjengelig. Det er en del
8162 programvare i skolen som er laget med utviklerverktøy som bare virker
8163 i windows, f.eks. Drillpro, LingDys/LingWrite. Det er også
8164 "programmer
" som bare virker om du har tilgang til Microsoft Office,
8165 f.eks. AskiRaski.

8167 <p
>Vi sliter også litt med at video-codecer ikke alltid er like lett å
8168 få opp å gå på klientene. Det er alltid en eller annen videosnutt fra

8173 <p

8174 bruker mest er Firefox (jobber med Chrome, fordi det er
8175 <strong

</strong

8176 over til LibreOffice), GIMP osv. Standardpakken av

8189 <p
>Jeg er langt i fra sikker. For det første handler det mye om at
8190 IKT-avdelingen i kommunen ofte er de som styrer hva som er IKT på
8191 skolene - og de liker å bruke avtalene med Microsoft, som de garantert
8192 har fra før. Dessuten - Select
6-avtalen til skolene gjør Microsoft
8193 skvettbillig.
</p

8195 <p
>Vi la vekt på effektiv drift av systemet - og at vi kunne øke
8196 antall maskiner uten å måtte øke budsjett for utstyr eller personell
8197 særlig mye, enn om vi hadde gått for en Microsoft-løsning. I praksis
8198 ser vi at en ren linux-installasjon driftes til halve prisen av en
8199 Microsoft-løsning.
</p
>
8201 <p
>Vi har i praksis også sett at det lærerne (og elevene) liker er at
8202 vi tilbyr
<strong

</strong

8203 vanlige i en Microsoft-løsning. Det er ikke så vanlig at
8204 <strong
>elevene
</strong

8205 også brukt som et vellykket argument mot Microsoft.
</p
>
8207 <p

8208 det. Problemet er å få dem som har makt til å bestemme det til faktisk

</p

8223 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong

8225 <p
>Jeg heter Astri Sletteng. Jeg er lærer og IKT veileder ved Håkvik
8226 skole i Narvik kommune. Min bakgrunn når det gjelder IKT: Av formell
8227 utdannelse har jeg lærerutdanning, Master i skoleledelse og IKT for
8228 lærere. Har jobba som IKT veileder siden
2002.
</p
>
8230 <p
>Det viktigste for meg som IKT veileder er å få fundamentert den
8231 5. basisferdigheten, digital kompetanse ved skolen min på en god måte
8232 slik at hele skolesamfunnet tar i bruk IKT i alle fag. Dette arbeidet
8233 gjøres i nært samarbeid med skolens ledelse.
</p
>
8235 <p
>Min viktigste jobb som IKT veileder er å være motivator og pådriver
8236 i IKT arbeidet ved skolen.
</p
>
8238 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
8240 <p
>Jobber i en kommune hvor vi satser på Fri programvare. I
2004 ble
8241 det gjort et politisk vedtak om at vi skulle innføre Skolelinux ved
8242 alle skolene i kommunen. Jeg har dermed en god del erfaring med
8243 Skolelinux, samt annen fri programvare som Open Office, Joomla, Moodle
8246 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
8248 <p
>Siden vi jobber med åpen kildekode kan vi få programmene og
8249 produktene tilpasset vår bruk. Det er jo heller ikke en ulempe at
8250 skolen kommer bedre ut økonomisk, men først og fremst er det viktig
8251 for oss at vi har digitale systemer som gjør at vi kan følge
8252 læreplanen i alle fag. Det syns jeg at vi kan gjøre gjennom
8253 Skolelinux.
</p
>
8255 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
8257 <p
>Skolen er avhengige av å ha folk på IT avdelinga i kommunen som kan
8258 drive support, og være tilgjengelige når vi trenger hjelp. Det er en
8259 ulempe at ikke alle på denne avdelingen nødvendigvis er god på
8262 <p
>Vi har også noen utfordringer når det kommer til spesielle
8263 programmer som enkelte elever er avhengige av ? og som ikke er
8264 plattform uavhengige. Her har vi i Friprog-verden, men også
8265 departement en jobb å gjøre.
</p
>
8267 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
8269 <p
>Skolen vår bruker Skolelinux, Open Office, Iceweazel (Mozilla),
8270 VLC, Tux paint, Scribus, FreeMind, GIMP, digiKam, Ksnapshot, GeoGebra,
8271 Moodle (innført på alle klassetrinn + som et administrativt verktøy)
8272 og Joomla som hjemmeside.
<p
>
8274 <p
>Det er de jeg kommer på i farten. I tillegg har vi Smartboard
8275 installert på server, men det regnes vel ikke som fri programvare?

><strong
>Hvilken strategi tror du er den rette å bruke for å få
8278 skoler til å ta i bruk fri programvare?
</strong

8280 <p
>Først og fremst trenger skolen oppetider på sine datasystemer. Syns
8281 også at det at vi kan få tilpasset plattform og systemer til vår bruk
8282 er en god strategi å bruke.

8298 <p
>Rubén Romero y Cordero,
81-modell, deltidspappa (
50%) for en jente
8299 på
6 år. Jobber i Oslo som Global Sales Executive hos Varnish Software
8300 og til daglig har jeg kontakt med kunder fra hele verden. Min
8301 forkjærlighet for fri programvare har gjort at jeg har nå flere års
8302 erfaring med salg av slike løsninger (bl.a. fra Redpill Linpro og
8303 Freecode) og mye innsikt og kunnskap om det globale IT-markedet.
8304 Ellers er jeg involvert i flere prosjekter bl.a. er jeg Ubuntu
8305 Community medlem, kontaktpersonen for Ubuntu Norge og driveren av
8306 SpreadUbuntu marketing prosjektet og nå fersk styremedlem i FRISK. Jeg
8307 har brukt GNU/Linux siden
1997.
</p

8309 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
8311 <p
>Som Debian bruker siden slutten av
90-tallet var det uunngåelig å
8312 ikke komme bort i Skolelinux. Dette var vel i slutten av
2001 når jeg
8313 var student ved UiO. Flere år senere fikk jeg lastet og testet Venus
8314 (Skolelinux
1.0) på release dagen.
</p
>
8316 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
8318 <p
>Fri programvare bygges sten for sten i det åpne, slik at koden og
8319 prosessen den lages på kan gjennomskues av andre enn de som har laget
8320 det. Det er et vitenskapelig og gjennomsiktig måte å lage programvare
8323 <p
>Skoler i vårt samfunn skal være steder hvor vitenskapelig kunnskap
8324 deles til alle. I dag har vi ikke et vitenskapelig tilnærming til
8325 hvordan programvaren som brukes på skolen lages. Skolelinux bringer
8326 inn at slik tilnærming i skoleverkets klasserom, siden
8327 operativsystemet er en åpent platform som gir skolene muligheten til å
8328 dra nytte av programvare som er laget av tusenvis av mennesker verden
8329 rundt og som gir elevene så vel som lærerne muligheten til å bruke,
8330 dele, forandre og forbedre OSet sitt uten begrensninger. I den
8331 forbindelsen representerer Skolelinux også konkrete resultater utfra
8332 samhandling på tvers av grenser.
</p
>
8334 <p
>Når det gjelder de tekniske fordelene av Skolelinux er jeg sikker
8335 på at andre enn meg har allerede beskrevet disse bedre enn det jeg
8336 kan. Men jeg kan likevel tilføye noe: Skolelinux som sådan er en
8337 community-drevet operativsystemplatform. Som i ethvert
8338 community-prosjekt har alle Skolelinux brukere muligheten til å
8339 påvirke retning av prosjektet og resultatet som gjenspeiles i
8340 programvaren. Dette kommer sjeldent frem og jeg mener at det er noe
8341 som burde fokuseres mer på.
</p
>
8343 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
8345 <p
>De største ulempene er:
</p
>
8348 <li
>Mangel på kompetanse
</li
>
8349 <li
>Mangel av administrative verktøy som kunne hjelpe lokale IT
8350 avdelinger å bruke Skolelinux til mer enn bare en tjener for
8351 terminalklienter. Et eksempel: Zentyal sin web-dashboard.
</li
>
8354 <p
>Bedre og mer intuitive administrative verktøy kunne løst deler av
8355 problemet, men det er unektelig at ved bruk av Skolelinux må
8356 IT-personalet vite hva de gjør for å få ting gjort riktig, eller i det
8357 hele tatt. Med andre platformer er kompetansen enklere tilgjengelig og
8358 løsningene kan fungere på en tilfredstillende, om ikke riktig
8361 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
8363 <p
>Har brukt GNU/Linux utelukkende sommitt skrivebord OS siden
2000. I
8364 dag bruker jeg Ubuntu og gjør det meste med friprogramvare verktøyene
8365 som er tilgjengelige der. Med over
20.000 programmer å velge mellom er
8366 dette mer enn nok for de fleste brukerne.

8368 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
8369 skoler til å ta i bruk fri programvare?
</strong
></p

8371 <p
>Opplysning og pragmatikk. Vi prøver å løse problemer med bruk av
8372 programvare. De fleste utfordringene skolene har på IKT-siden kan
8373 løses ved hjelp av friprogramvareverktøy i dag. Det som trenges er
8374 opplysning, kunnskap og kompetanse.

8401 <p
>Skolelinux har jeg møtt ved flere anledninger opp gjennom åra, både gjennom
8402 entusiastiske skolelinuxbrukere og skeptiske
"forståsegpåere
" :-)
</p
>
8404 <p
>Jeg husker en leverandør av et stort OS for noen år siden mente at
8405 Skolelinux var kun for hackere og nerder og at ingen seriøse skoler
8406 kunne ta dette i bruk. Heldigvis er kunnskapen større nå og
8407 skikkelige
"IT-folk
" søker alltid å utvide sin kunnskap.
8409 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
8411 <p
>Ja det er mange fordeler. Uavhengighet, stabilitet, åpenhet, standarder
8412 osv. Tror det er viktig at man ikke begrenser mulighetene på den plattformen
8413 elevene skal jobbe.
</p
>
8415 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
8417 <p
>Det største hinderet er det vi opplever på andre områder rundt
8418 fri programvare, nemlig kunnskap. For mange er det trygt å velge det vi
8419 alltid har valgt. Fordi leverandørene rundt oss sitter på den kunnskapen og
8420 de vi støtter oss på har den samme. Hvis vi klarer å riste løs litt og
8421 glemme gamle kriger mellom operativsystemer og leverandører, men sette ned
8422 hva som er viktig og velge ut fra det, så hadde man kanskje kommet ut med
8423 litt andre resultat. Jeg tror IT-folk er konservative og velger tradisjonelt
8424 og det er synd.
</p
>
8426 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong

>
8428 <p
>Jeg bruker Ubuntu, Android, Jolicloud, Open Office, Zimbra, Picasa
8429 og Firefox samt en bråte med tjenester som er webbasert. Det eneste
8430 som er betalingslisens for er OSX. Ser at jeg jobber mer og mer i
8431 skyen og setter pris på alt jeg slipper egen klient til. Derfor er
8432 jeg veldig sjarmert av små kjappe operativsystemer som krever minimalt
8433 av maskinvaren.

><strong
>Hvilken strategi tror du er den rette å bruke for å få
8436 skoler til å ta i bruk fri programvare?

8438 <p
>Tror en blanding av krav og informasjon er veien å gå. Krav om
8439 sikkerhet, oppetid og åpne standarder. Informasjon om muligheter og
8440 alternativer. Her har leverandører, IT-avdelinger og pedagoger en vei
8441 å gå sammen. Det er til slutt LÆRING det dreier seg om, og da må man
8442 få mest mulig læring for pengene man har.

>Sturle Sunde, ansvarleg for skulenettet i Flora kommune. Eg driv,
8460 vidareutviklar og er andrelinje brukarstøtte for datanettet ved
8461 skulane i Flora kommune.
10 skular og meir enn
700 maskiner med
8462 Linux, medrekna tynnklientar. Tidlegare jobba eg i mange år med
8463 unix-drift ved Universitetets senter for informasjonsteknologi ved
8464 Universitetet i Oslo.

8466 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p

8468 <p
>Det er vanskeleg å svare konkret på. Eg har drive med Unix og Linux i
8469 alle år, og Skulelinux er eit godt kjent prosjekt i miljøet. Det var
8470 først i
2008, då eg tok til i min noverande jobb, at eg fekk bruk for
8471 Skulelinux for alvor.
</p
>
8473 <p
>Jobben min skulle vere drift av eit nytt skulenett i Flora kommune,
8474 levert av eit firma eg ikkje vil reklamere for. Systemet skulle vere
8475 ferdig levert i september året før. Dette viste seg å ta mykje lenger
8476 tid, og i haustferien
2008 hadde dei endå ikkje klart å få opp ei
8477 fungerande løysing. Situasjonen var prekær for den største skulen i
8478 kommunen med meir enn
500 elevar på ungdomssteget. Skulen hadde brukt
8479 Skulelinux før, og var tilfredse med det. No hadde dei vore utan
8480 fungerande datasystem i nesten eit år. Difor fekk eg opp ein ny tenar
8481 utanfor prosjektet og installerte Skulelinux på den. Etter litt
8482 justering av konfigurasjonen med god hjelp av #skolelinux på IRC, var
8483 den nye tenaren oppe og gjekk med både tynne og halv-tjukke klientar.
8484 Autentisering gjekk mot det nye systemet, slik at elevar og lærarar
8485 framleis har same brukarnamn og passord over alt. Dette berre
8486 fungerte, og vi bestemte oss for å erstatte delar av løysinga vi
8487 skulle få levert med Skulelinux.
</p
>
8489 <p
>Det høyrer med til historia at det nye systemet eg skulle drive frå
8490 januar
2008 endå ikkje er ferdig levert. Dei jobbar med saka, seier
8491 dei, og har von om å fullføre leveransen i løpet av
2011.
</p
>
8493 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
8495 <p
>Det er veldig mange. Eg skal ta nokre få.
</p
>
8497 <p
>Den viktigaste fordelen er at det igrunn berre er ei maskin å passe
8498 på, og det er tenaren. Med andre løysingar har ein gjerne programvare
8499 og anna som skal vedlikehaldast på kvar enkelt maskin. Med Skulelinux
8500 kan alle feil rettast og alle program oppgraderast på alle maskiner
8501 samstundes ved å gjere endringa som må til på tenaren. Eg kan sitje
8502 på kontoret og passe på alle tenarane i kommunen derifrå.
</p
>
8506 <li
>Tynne klientar gjer det mogleg å bruke eldre utstyr lenge, so lenge
8507 tenaren er sterk nok. Ein liten tenar med eit par halv-moderne CPUar
8508 og
2 GiB RAM held lenge for eit typisk klasserom med
30 tynnklientar,
8509 og det er lett å utvide med fleire.
8511 <li
>Halvtjukke klientar gjer det mogleg å utnytte kapasiteten i litt
8512 nyare maskiner betre, og avlaste tenaren. Ingenting vert installert
8513 lokalt på desse heller, og harddisken kan gjerne koblast frå. Gode
8514 halvtjukke klientar kan kjøpast brukt for under
1000-lappen, og det er
8515 heile kostnaden. Ingen lisensar eller anna på toppen, og det er ikkje
8516 krav til kraftigare tenar heller.
8518 <li
>Det er Linux. Vi har ikkje noko kluss med drivarar, dei berre er
8519 der. Heller ikkje med virus, dei finst i realiteten ikkje. Eller med
8520 elevar som klussar med installert programvare, for dei klarar ikkje å
8521 øydeleggje for nokon andre enn seg sjølve.
8525 <p
>Skulelinux er lagt opp til å vere veldig lett å installere rett ut
8526 av boksen på ein heil skule av ein interessert lærar. Det er ofte ei
8527 god løysing for skulen. Å ha nokon til stades som kjenner systemet og
8528 kan forklare enkle ting eller løyse problem der og då, er uvurderleg
8529 viktig for ein stressa lærar fem minutt før det ringer inn.
</p
>
8531 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
8533 <p
>All den ferdige konfigurasjonen gjer det tungvint å tilpasse
8534 Skulelinux til eit system som skal fungere saman med mange andre
8535 installasjonar i eit felles datanett for skulane i ein kommune. Det
8536 heile er prekonfigurert for ein skule, og utviding til mange skular
8537 med eigne tenarar er ikkje berre enkelt.

8553 gjere å gjere det enkelt for skulane å finne Skulelinux, og gjere det
8554 enkelt for dei å få hjelp til installasjon på skulen. Gjerne med
8555 lokale kontaktpersonar. Her er det dugnadsinnsats som må til, for
8556 desse skulane har ikkje råd til å betale for dette.

8558 <p
>Den andre og kanskje viktigare målgruppa er dei meir eller mindre
8559 profesjonelle kundane. Alle store offentlege innkjøp, inkludert
8560 innkjøp av nytt datasystem for skular, må ut på offentleg anbod.
8561 Offentlege anbod er mykje meir lukka enn dei gjev inntrykk av, og både
8562 regelboka og boka med triks for å sminke tilbodet er tjukk. Det er
8563 vanskeleg å komme inn utan eit solid salsapparat i ryggen. Kanskje
8564 Skulelinux skulle prøve aktivt å få seg eit partnarskap med eit av dei
8565 store som gjerne vil sterkare inn på den offentlege IT-marknaden?
8566 Nokon som kjenner triksa og har krefter til å ta opp kampen mot både
8567 dårlege anbod og Rudolf Blostrupmoen IT AS. Leveranse til skulane i
8568 ein kommune er ein god måte å få ein fot inn døra som leverandør til
8569 ein lukrativ kommunemarknad som kjøper alle tenester. Ta kontakt med
8570 nokon som er passeleg store og ikkje er Microsoft-partnar, og fortell:
8571 «Vi har eit ferdig produkt som du kan selje. Nei vi skal ikkje ha for
8572 det. Du kan gjerne gjere kva du vil med det, berre vi får lov til å
8573 hjelpe deg. Målgruppa er alle kommunar, og det er noko dei vil ha.
8574 Det er eit godt produkt, brukt av mange og godt likt.»

>Embrik Kaslegard,
1964-modell, fire barn (
7-
20 år). Begynte som
8591 lærer i
1989 - har hatt IKT-ansvar siden første året i jobb. Har
8592 jobbet som lærer/IKT-ansvarlig uavbrutt siden
1989. Jobbet med
8593 Skolelinux fra
2004 til
2010. Nå har jeg fått ny arbeidsplass og er
8594 40% lærer og
60% IKT med Windows XP, Win2003 server og et regionalt
8595 IKT-regime som legger premissene og begrensingene for hva vi kan gjøre
8596 på skolen.

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

8600 <p
>Jeg leste en artikkel om en dugnadsinstallasjon av Skolelinux på en
8601 skole på Jæren et sted. Tanken om dugnad og frihet appellerte til
8602 meg. Da vi skulle bygge ny skole var det en del vi måtte spare på,
8603 fordi vi beveget oss mot en kostnadssprekk. Kabling og investering i
8604 PC-er var en av tingene vi sparte på. Derfor kjøpe vi
72 pc-er for
390
8605 pr stk. En filtjener og en applikasjonsserver.

8607 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
8609 <p
>Fordelen er at så mye er satt opp fra starten. I tillegg er det
8610 tydelig at pakka er laga for skoleverket. Brukerne har egne
8611 skrivebord, tilgang på mange gode verktøyprogrammer. Vi slipper å
8612 tenke på virus. Brukerne har ikke mulighet til å ødelegge
8613 klientoppsett, men har gode muligheter til å endre eget oppsett. Dette
8614 tror jeg er inspirerende og kjekt for mange brukere. Mappestrukturen
8615 er ferdig og det er
"enkelt
" å designe lokale mappestrukturer via
8616 skeleton. Noen av oss i skoleverket mener skolen skal være en
8617 "mot-kultur
". Da er Skolelinux et av valgene man kan ta. Et annet er å
8618 spise på indisk restaurant i stedet for Mc Donald
's når vi er på bytur
8619 osv.. Ordene deling, frihet, dugnad osv er positive ord i
8620 skoleverket. Det er viktig at elevene blir bevisst dette.

8622 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
8624 <p
>Kompabiliteten er selvsagt et problem, selv om det er mindre nå enn
8625 før. For IKT-personer på skolene som skal drifte dette er det
8626 problematisk med kommandoer i terminalen. I tillegg er det alt for
8627 mange programmer i Skolelinux som ikke blir brukt. Jeg tror
8628 Skolelinux er tjent med å tone ned begrepet pedagogisk programvare.
8629 Slik jeg ser det finnes ikke denne kategorien programmer lengre slik
8630 de gjorde før, som frittsående programmer som installeres på en
8631 datamaskin eller på serveren. Det finnes en del spesialpedagogiske
8632 programmer, som Textpilot, LingDys, LingRight, AskiRaski, Ny i Norge
8633 osv. Men dette er programmer for enkelt-elever eller små grupper av
8634 elever. Det som bør være fokus er at alle undervisningsressurser som
8635 lages for nettet skal være nettleseruavhengig.

8637 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
8639 <p
>OpenOffice bruker jeg til vanlig kontorarbeide. VLC bruker jeg som
8640 videoavspiller og av og til streaming av film. Gimp bruker jeg i
8641 undervisningen til bildemanipulering. Firefox og Chrome er mine
8642 favoritt-nettlesere. Firefox har lenge vært førstevalget mitt, nå
8643 bruker jeg mest Chrome. Opplever den som raskere og smidigere enn
8644 Firefox. Ubuntu bruker jeg som dualboot på jobb-maskinen min i
8645 tillegg til at alle PCer hjemme har en eller annen Ubuntu-distribusjon
8646 installert. Jeg bruker Clonezilla på Ubuntu
10.04 til kloning av
8647 datamaskiner på jobb. Det er selvsagt en haug andre frie programmer
8648 jeg bruker men jeg bruker dem ikke daglig. Jeg kan ramse opp:
8649 recordmydesktop, cinelerra, acidrip, soundjuicer, audacity, NX
8650 (no-machine), Kino, Rythmbox...

8652 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
8653 skoler til å ta i bruk fri programvare?
</strong
></p
>
8655 <p
>Jeg tror oppsøkende virksomhet er den rette strategien.
8656 Ressurspersoner gjør avtaler med rådmenn, skolesjefer, rektorer. Det
8657 er slik konkurrentene gjør det. Fokuset i slike samtaler bør være
8658 kost-nytte. Dersom personer med økonomisk ansvar ser at de kan få
8659 like godt tilbud til mindre utgifter, tror jeg det er mulighet til å
8660 få innpass. Dersom de også kan få konkrete tilbud på drift i slike
8661 samtaler, vil de kanskje bli litt mer interesserte i hvor mye penger
8662 som faktisk går til IKT i skolene. Det er også viktig at vi ikke
8663 firer for mye på krav til datamaskiner. Det er flott at Skolelinux
8664 går på
"utrangert
" utstyr, men dette bør bare presenteres som et
8665 alternativ. Skolelinux-installasjoner med utrangert utstyr er ikke å
8666 foretrekke dersom man kan unngå det. Det skaper ikke entusiasme hos
8667 brukerne (elever og lærere) når de bruker gamle datamaskiner som går
8668 tregt. Det er kjempefint med skoler som har kommet seg frem til
8669 Skolelinux og fri programvare av seg selv, men de lever på nåde.
8670 Slike valg må fundamenteres hos skoleeier.

17
8694 servere basert på Skolelinux og Debian. Jeg holder i tillegg noen kurs

8701 <p
>Gjennom en eller annen nettavis i
2001 der var det skrevet om
8702 Skolelinux. Artikkelen ga meg lyst til å prøve ut systemet.
</p
>
8704 <p
>Det startet i
2002 ved at jeg installerte en av de første utgavene
8705 av Skolelinux på en standard pc på Solneset skole i Tromsø. Denne var
8706 oppe fram til desember
2003 da jeg sluttet på den skolen og begynte i
8707 ny jobb i Narvik kommune.
</p

8709 <p
> I Narvik kommune var det i
2004 kun
2 servere på da totalt
15
8710 skoler. Disse var Windows NT baserte. På disse to skolene var det lite
8711 med maskiner. Jobben med å få Narvik Kommune opp på akseptabelt nivå
8712 virket å være formidabel. Men med hjelp av gode kollegaer og leder
8713 skrev jeg en IKT plan for Narvik kommune som ble vedtatt av politikere
8714 i august
2004. I denne planen ble det bestemt at Narvik kommune skulle
8715 bruke Skolelinux. Her ble det også satt av midler til kabling av god
8716 infrastruktur på alle skoler samt innkjøp av nye datamaskiner. Så i
8717 dag har vi
17 servere hvorav
13 er på Skolelinux, med ca
1500 klienter
8718 basert på tynne,
"halvtykke
" og et stort antall bærbare pcer basert på

8735 <p

8736 nettbaserte programmer istedet for å installere lokalt. Dette med
8737 enkelte leverandører som ikke kan levere programmer til Linux er et
8738 lite problem og over tid tror jeg at denne barrieren er borte.

8800 pilotprosjekt med Skolelinux, som egentlig var og er en stor suksess,
8801 men det virker ut som det ikke skjer noe mer på. I tillegg var vi med

8851 <br
>av Inspektør Siri (gjest)
8853 <p
>Kommunen min har to omtrent jevnstore tettsteder, og en
8854 ungdomsskole i hvert av tettstedene. Den minste av disse har ca
300
8855 elever og til denne sogner det
3 barneskoler. Den største har ca
350
8856 elever og til denne sogner det
4 barneskoler.
</p
>
8860 <li
>Kommunen har i veldig lang tid forsømt IKT i skolen, og det har
8861 bare blitt gitt smuler i ny og ne. Det er kun den største av
8862 ungdomsskolene som har hatt en skikkelig datapark, og dette takket
8863 være en naturfaglærer som ble lei av å vente på kommunen. Det gjorde
8864 at vi bestemte oss for å ta ting i egne hender, og da vha
8865 skolelinux. En testinstallasjon med
10 gamle PCer ble gjort, og vi så
8866 raskt at dette var veldig lovende. Neste etappe var å gi alle lærere
8867 egen PC på arbeidsplassene sine (
2004), og så sette opp
16 PCer på to
8868 datarom. Vi har kun basert oss på å kjøpe inn brukte maskiner, og
8869 aldri dyrere enn
1000 kr pr klient. For to år siden så hadde vi
8870 klienter i alle klasserom, og totalt hadde vi da rundt
250 stk. Rundt
8871 40 klienter brukes av lærerne og kjører på en egen server. Elvene har
8872 resten, og kjører også en egen server. Servere har vi også kjøpt
8873 brukt,
2 år gamle servere koster
6-
7000 kroner.
</li
>
8875 <li
>Skolen vår er et relativt gammelt bygg, men en meget dyktig
8876 vaktmester har sammen med IKT-ansvarlig/Naturfaglærer lagt kabler til alle
8877 rom. Gradvis har vi byttet ut billige svitsjer med mer solide saker
8878 som er mulig å fjernstyre.
</li
>
8880 <li
>Vi har i all hovedsak greid å få dette til over eget budsjett, men
8881 vi har også passet på å få penger når de andre skolene har fått
8882 bærbare PCer til lærere osv.
</li

8884 <li
>Vår IKT-ansvarlig har gjort (og gjør) en fenomenal jobb, og vi har
8885 en maskinpark som de andre av kommunens skoler bare kan drømme
8890 <p
>Så skjer det som ofte skjer. Det kommer en eller annen
8891 selger/blåruss og skal fikse ALT. I vårt tilfelle betyr dette også
8892 sentralisering av drift. Den ny-ansatte på kommunens IT-avdelingen
8893 skal også ha jobb, og ser for seg å ta over skoledriften. Kommunen
8894 kjøper inn eksterne driftstjenester, og nekter i samme slengen å ta
8895 hensyn til skolen vår. Dette til tross for at vi alene har like mange
8896 datamaskiner som de andre til sammen.
</p
>
8900 <li
>Det blir krevd at vi skal innlemmes i de kommunale systemet, og
8901 det er VI som får ansvar for at dette kommer på plass. Og det er her
8902 de horrible tingene begynner å skje.

8909 at vi må bruke en terminalløsning mot kommunal server. Ikke i seg selv

8911 faktisk å åpne de porter OSV som vi måtte bruke.

8925 sitte ved hver sin PC. Og de har fått tilbakemelding (klager) fra VGS
8926 om manglende datakompetanse på elevene som kommer fra dem. Dette fører
8927 videre til at kommunen endelig innser at de må ta grep.

8932 og det skal satses på bærbare maskiner. Siden vi ikke har fått tatt
8933 del i prosessene som angår oss, så bruker vi fagforening. Vi har ikke
8934 blitt hørt i forbindelse med endringer som er betydelig for vår
8935 hverdag, og greier å stoppe omlegging. I tillegg så har vi et politisk

>Jeg glemte å nevne at vi nå nesten ikke bruker tid på å drifte
9024 systemet vårt, noe som gjør at det aller meste av tid blir brukt til å
9025 støtte lærerne og elevene. F.eks så bruker vår IKT-ansvarlig den
9026 første timen på jobb,
0730-
0830 kun til å gå ute på arbeidsplassene
9027 til læreren. Dette for å kunne svare på små og store problem, gi tips
9028 og råd, eller bare for å plukke opp hva som er behovet ute i
9029 undervisningsarealene. Det er dessverre ikke slik at alle lærerne har
9030 nok digital kompetanse til å kunne formulere alle spørsmålene de har,
9031 men ved å kunne få vise eller lufte tanker med IKT-ansvarlig så er det
9032 utrolig hva som kommer fram.
</p

9036 <li
>Jeg ser at mange bruker økonomi som argument i forhold til å bruke
9037 SkoleLinux, og jeg skal ikke legge skjul på at det var dette som i
9038 utgangspunktet var årsaken til vårt valg. Men diskusjonene og kampen
9039 med kommunens IT-avdeling har gjort at vi har fått et noe annet
9040 fokus. Fordelene med drift og stabilitet, gjør at vi ville ha valgt
9041 samme løsning selv om den var dyrere. At vi slipper langt billigere
9042 unna, som følge av
0,- lisenskostnader og lave maskinvarekostnader, er
9043 bare en bonus.
</li
>
9045 <li
>Etter å ha kranglet oss til å få skikkelig oversikt over hva de
9046 andre skolene i kommunen bruker på IT, så har vi fått gehør for å få
9047 samme midler til innkjøp. Dette har gjort at vi nå kan kjøpe inn
9048 utstyr som de andre skolene bare kan se langt etter. Vi har nettopp
9049 kjøpt inn
3 videokamera i semiproff-klassen for å kunne lage film,
9050 samt sende live fra skoleteater/konserter. Vi har kjøpt inn digitale
9051 kompaktkamera til alle klassene. Vi har et team av lærere som skal i
9052 gang med å teste ut tablets på svake elever. Håpet et at teknologien
9053 kan være med på å gi noen av elevene litt mer motivasjon. Vi har kjøpt
9054 inn et halvt klassesett med pulsklokker, noe som har vist seg å være
9055 overraskende inspirerende for en del av elevene. Vi har også oss på
9056 fag på en høyskole litt lengre sør for oss, slik at
3 av oss nå skal
9057 ta faget
"Linux tjenestedrift
". Som inspektør og en del av skolens
9058 administrasjon er det veldig praktisk å kunne trå til hvis det
9059 kniper. Men IKT-ansvarlig har vært UTROLIG flink til å lage rene
9060 smørbrødlister for hvordan de mest vanlige driftsproblem løses, så det
9061 er lett for flere av oss å ta del i den daglige driften. Vi har svært
9062 stor nytte av lærling (som også hjelper to av naboskolene), men det er
9063 nesten blitt slik at det er om å gjøre å komme til først for å få løse
9064 problem. Det å få fingrene på problem og utfordringer er den aller
9065 beste læremester.

9078 håper at vi nå framover kan få tid til å bidra. Vi er i ferd med å
9079 bytte ut en av serverne våre, og da vil denne trolig bli satt opp som
9080 testserver for neste versjon av Skolelinux. På den måten vil vi i alle
9081 fall kunne gi tilbakemeldinger og rapportere feil. I tillegg så vil

9215 <description><p
>In the latest issue of Linux Journal, the readers choices were
9216 presented, and the winner among the multimedia player were VLC.
9217 Personally, I like VLC, and it is my player of choice when I first try
9218 to play a video file or stream. Only if VLC fail will I drag out
9219 gmplayer to see if it can do better. The reason is mostly the failure
9220 model and trust. When VLC fail, it normally pop up a error message
9221 reporting the problem. When mplayer fail, it normally segfault or
9222 just hangs. The latter failure mode drain my trust in the program.
<p
>
9224 <p
>But even if VLC is my player of choice, we have choosen to use
9225 mplayer in
<a href=
"http://www.skolelinux.org/
">Debian
9226 Edu/Skolelinux
</a
>. The reason is simple. We need a good browser
9227 plugin to play web videos seamlessly, and the VLC browser plugin is
9228 not very good. For example, it lack in-line control buttons, so there
9229 is no way for the user to pause the video. Also, when I
9230 <a href=
"http://wiki.debian.org/DebianEdu/BrowserMultimedia
">last
9231 tested the browser plugins
</a
> available in Debian, the VLC plugin
9232 failed on several video pages where mplayer based plugins worked. If
9233 the browser plugin for VLC was as good as the gecko-mediaplayer
9234 package (which uses mplayer), we would switch.
</P
>
9236 <p
>While VLC is a good player, its user interface is slightly
9237 annoying. The most annoying feature is its inconsistent use of
9238 keyboard shortcuts. When the player is in full screen mode, its
9239 shortcuts are different from when it is playing the video in a window.
9240 For example, space only work as pause when in full screen mode. I
9241 wish it had consisten shortcuts and that space also would work when in
9242 window mode. Another nice shortcut in gmplayer is [enter] to restart
9243 the current video. It is very nice when playing short videos from the
9244 web and want to restart it when new people arrive to have a look at
9245 what is going on.

9701 are virtual machines. And they have been Xen machines running on a
9702 fairly old IBM eserver xseries
345 machine, and we wanted to migrate
9703 them to KVM on a newer Dell PowerEdge
2950 host machine. This was a
9704 bit harder that it could have been, because we set up the Xen virtual
9705 machines to get the virtual partitions from LVM, which as far as I
9706 know is not supported by KVM. So to migrate, we had to convert
9707 several LVM logical volumes to partitions on a virtual disk file.

">a
9711 nice recipe
</a

9712 migration. It uses qemu-img from the qemu package to make the disk
9713 image, parted to partition it, losetup and kpartx to present the disk
9714 image partions as devices, and dd to copy the data. I NFS mounted the
9715 new servers storage area on the old server to do the migration.

10012 machine as well. I have also considered using the kfreebsd
10013 architecture in Debian as a file server in NUUG to get access to the
5
10014 TB zfs volume we currently use to store DV video. Because of this, I
10015 finally got around to do a test installation of Debian/Squeeze with
10016 kfreebsd. Installation went fairly smooth, thought I noticed some
10017 visual glitches in the cdebconf dialogs (black cursor left on the
10018 screen at random locations). Have not gotten very far with the
10019 testing. Noticed cfdisk did not work, but fdisk did so it was not a
10020 fatal problem. Have to spend some more time on it to see if it is
10021 useful as a file server for NUUG. Will try to find time to set up a
10022 gnash buildbot slave on the Debian Edu/Skolelinux this weekend.

>Prioritising packages for the Debian Edu /

</a
> DVD, which is
10033 supposed provide a school with all the services and user applications
10034 needed on the pupils computer network has always been hard. Even
10035 schools without Internet connections should be able to get Debian Edu
10036 working using this DVD.
</p
>
10038 <p
>The job became a lot harder when apt and aptitude started
10039 installing recommended packages by default. We want the same set of
10040 packages to be installed when using the DVD and the netinst CD, and
10041 that means all recommended packages need to be on the DVD. I created
10042 a patch for debian-cd in
<a href=
"http://bugs.debian.org/
601203">BTS
10043 report #
601203</a
> to do this, and since this change was applied to
10044 the Debian Edu DVD build, we have been seriously short on space.
</p
>
10046 <p
>A few days ago we decided to drop blender, wxmaxima and kicad from
10047 the default installation to save space on the DVD, believing that
10048 those needing these applications are few and can get them from the
10049 Debian archive.
</p
>
10051 <p
>Yesterday, I had a look what source packages to see which packages
10052 were using most space. A few large packages are well know;
10053 openoffice.org, openclipart and fluid-soundfont. But I also
10054 discovered that lilypond used
106 MiB and fglrx-driver used
53 MiB.
10055 The lilypond package is pulled in as a dependency for rosegarden, and
10056 when looking a bit closer I discovered that
99 MiB of the
106 MiB were
10057 the documentation package, which is recommended by the binary package.
10058 I decided to drop this documentation package from our DVD, as most of
10059 our users will use the GUI front-ends and do not need the lilypond
10060 documentation. Similarly, I dropped the non-free fglrx-driver package
10061 which might be installed by d-i when its hardware is detected, as the
10062 free X driver should work.
</p
>
10064 <p
>With this change, we finally got space for the LXDE and Gnome
10065 desktop packages as well as the language specific packages making the
10066 DVD more useful again.

10078 raise money for the project is going well. The lower limit of
10

13 people have signed it.
10080 More signers and more funding is most welcome, and I am really curious
10081 how far we can get before the time limit of December
24 is reached.
10084 <p
>On the #gnash IRC channel on irc.freenode.net, I was just tipped
10085 about what appear to be a great code coverage tool capable of
10086 generating code coverage stats without any changes to the source code.

10090 It is missing in Debian, but the git source built just fine in Squeeze
10091 after I installed libelf-dev, libdwarf-dev, pkg-config and
10092 libglib2.0-dev. Failed to build in Lenny, but suspect that is
10093 solvable. I hope kcov make it into Debian soon.

10125 schools experienced with
<a href=
"http://www.skolelinux.org/
">Debian
10126 Edu/Skolelinux
</a
> was the lack of working Flash. A lot of educational
10127 web sites require Flash to work, and lacking working Flash support in
10128 the web browser and the problems with installing it was perceived as a
10129 good reason to stay with Windows.

10131 <p

10132 said to be the retarded cousin that did not really understand
10133 everything you told him but could work fairly well. This was a
10134 comment regarding the problems Linux have with proprietary formats and
10135 non-standard web pages, and is sad because it exposes a fairly common
10136 understanding of whose fault it is if web pages that only work in for
10137 example Internet Explorer
6 fail to work on Firefox, and funny because
10138 it explain very well how annoying it is for users when Linux
10139 distributions do not work with the documents they receive or the web
10140 pages they want to visit.
</p

10142 <p
>This is part of the reason why I believe it is important for Debian
10143 and Debian Edu to have a well working Flash implementation in the
10144 distribution, to get at least popular sites as Youtube and Google
10145 Video to working out of the box. For Squeeze, Debian have the chance
10146 to include the latest version of Gnash that will make this happen, as
10147 the new release
0.8.8 was published a few weeks ago and is resting in
10148 unstable. The new version work with more sites that version
0.8.7.
10149 The Gnash maintainers have asked for a freeze exception, but the
10150 release team have not had time to reply to it yet. I hope they agree
10151 with me that Flash is important for the Debian desktop users, and thus
10152 accept the new package into Squeeze.

>As reported earlier, the last few days I have looked at how Debian
10327 Edu clients are configured, and tried to get rid of all hardcoded
10328 configuration settings on the clients. I believe the work to be
10329 mostly done, and the clients seem to work just fine with dynamically
10330 generated configuration.
</p
>
10332 <p
>What is the point, you might ask? The point is to allow a Debian
10333 Edu desktop to integrate into an existing network infrastructure
10334 without any manual configuration.
</p
>
10336 <p
>This is what happens when installing a Debian Edu client here at
10337 the University of Oslo using PXE. With the PXE installation, I am
10338 asked for language (Norwegian Bokmål), locality (Norway) and keyboard
10339 layout (no-latin1), Debian Edu profile (Roaming Workstation), if I
10340 accept to reformat the hard drive (yes), if I want to submit info to
10341 popcon.debian.org (no) and root password (secret). After answering
10342 these questions, the installer goes ahead and does its thing, and
10343 after around
50 minutes it is done. I press enter to finish the
10344 installation, and the machine reboots into KDE. When the machine is
10345 ready and kdm asks for login information, I enter my university
10346 username and password, am told by kdm that a local home directory has
10347 been created and that I must log in again, and finally log in with the
10348 same username and password to the KDE
4.4 desktop. At no point during
10349 this process did it ask for university specific settings, and all the
10350 required configuration was dynamically detected using information
10351 fetched via DHCP and DNS. The roaming workstation is now ready for
10354 <p
>How was this done, you might wonder? First of all, here is the
10355 list of things that need to be configured on the client to get it
10356 working properly out of the box:
</p
>
10359 <li
>IP address/netmask and DNS server.
</li
>
10360 <li
>Web proxy URL.
</li
>
10361 <li
>LDAP server for NSS directory information (user, group, etc).
</li
>
10362 <li
>Kerberos server for PAM password checking.
</li
>
10363 <li
>SMB mount point to access the network home directory. (*)
</li
>
10364 <li
>Central syslog server to send syslog messages to. (*)
</li
>
10365 <li
>Sitesummary collector URL to submit info to central server. (*)
</li
>
10368 <p
>(Hm, did I forget anything? Let me knew if I did.)
</p
>
10370 <p
>The points marked (*) are not required to be able to use the
10371 machine, but needed to provide central storage and allowing system
10372 administrators to track their machines. Since yesterday, everything
10373 but the sitesummary collector URL is dynamically discovered at boot
10374 and installation time in the svn version of Debian Edu.
</p
>
10376 <p
>The IP and DNS setup is fetched during boot using DHCP as usual.
10377 When a DHCP update arrives, the proxy setup is updated by looking for
10378 http://wpat/wpad.dat and using the content of this WPAD file to
10379 configure the http and ftp proxy in /etc/environment and
10380 /etc/apt/apt.conf. I decided to update the proxy setup using a DHCP
10381 hook to ensure that the client stops using the Debian Edu proxy when
10382 it is moved outside the Debian Edu network, and instead uses any local
10383 proxy present on the new network when it moves around.
</p
>
10385 <p
>The DNS names of the LDAP, Kerberos and syslog server and related
10386 configuration are generated using DNS information at boot. First the
10387 installer looks for a host named ldap in the current DNS domain. If
10388 not found, it looks for _ldap._tcp SRV records in DNS instead. If an
10389 LDAP server is found, its root DSE entry is requested and the
10390 attributes namingContexts and defaultNamingContext are used to
10391 determine which LDAP base to use for NSS. If there are several
10392 namingContexts attibutes and the defaultNamingContext is present, that
10393 LDAP subtree is used as the base. If defaultNamingContext is missing,
10394 the subtrees listed as namingContexts are searched in sequence for any
10395 object with class posixAccount or posixGroup, and the first one with
10396 such an object is used as the LDAP base. For Kerberos, a similar
10397 search is done by first looking for a host named kerberos, and then
10398 for the _kerberos._tcp SRV record. I
've been unable to find a way to
10399 look up the Kerberos realm, so for this the upper case string of the
10400 current DNS domain is used.

>For the syslog server, the hosts syslog and loghost are searched
10403 for, and the _syslog._udp SRV record is consulted if no such host is
10404 found. This algorithm works for both Debian Edu and the University of
10405 Oslo. A similar strategy would work for locating the sitesummary
10406 server, but have not been implemented yet. I decided to fetch and
10407 save these settings during installation, to make sure moving to a
10408 different network does not change the set of users being allowed to
10409 log in nor the passwords required to log in. Usernames and passwords
10410 will be cached by sssd when the user logs in on the Debian Edu
10411 network, and will not change as the laptop move around. For a
10412 non-roaming machine, there is no caching, but given that it is
10413 supposed to stay in place it should not matter much. Perhaps we
10414 should switch those to use sssd too?
</p
>
10416 <p
>The user
's SMB mount point for the network home directory is
10417 located when the user logs in for the first time. The LDAP server is
10418 consulted to look for the user
's LDAP object and the sambaHomePath
10419 attribute is used if found. If it isn
't found, the home directory
10420 path fetched from NSS is used instead. Assuming the path is of the
10421 form /site/server/directory/username, the second part is looked up in
10422 DNS and used to generate a SMB URL of the form
10423 smb://server.domain/username. This algorithm works for both Debian
10424 edu and the University of Oslo. Perhaps there are better attributes
10425 to use or a better algorithm that works for more sites, but this will
10426 do for now. :)

10428 <p
>This work should make it easier to integrate the Debian Edu clients
10429 into any LDAP/Kerberos infrastructure, and make the current setup even
10430 more flexible than before. I suspect it will also work for thin
10431 client servers, allowing one to easily set up LTSP and hook it into a
10432 existing network infrastructure, but I have not had time to test this

2010-
08-
09: Simon Farnsworth gave me a heads-up on how to
10439 detect Kerberos realm from DNS, by looking for _kerberos TXT entries
10440 before falling back to the upper case DNS domain name. Will have to
10441 implement it for Debian Edu. :)

10450 <description><p
>A few years ago, I was involved in a project planning to use
10451 Windows file servers as home directory servers for Debian
10452 Edu/Skolelinux machines. This was thought to be no problem, as the
10453 access would be through the SMB network file system protocol, and we
10454 knew other sites used SMB with unix and samba as the file server to
10455 mount home directories without any problems. But, after months of
10456 struggling, we had to conclude that our goal was impossible.
</p
>
10458 <p
>The reason is simply that while SMB can be used for home
10459 directories when the file server is Samba running on Unix, this only
10460 work because of Samba have some extensions and the fact that the
10461 underlying file system is a unix file system. When using a Windows
10462 file server, the underlying file system do not have POSIX semantics,
10463 and several programs will fail if the users home directory where they
10464 want to store their configuration lack POSIX semantics.
</p
>
10466 <p
>As part of this work, I wrote a small C program I want to share
10467 with you all, to replicate a few of the problematic applications (like
10468 OpenOffice.org and GCompris) and see if the file system was working as
10469 it should. If you find yourself in spooky file system land, it might

>A few days ago, I
10682 <a href=
"http://people.skolelinux.org/pere/blog/Debian_Edu_roaming_workstation___at_the_university_of_Oslo.html
">tried
10683 to install
</a
> a Roaming workation profile from Debian Edu/Squeeze
10684 while on the university network here at the University of Oslo, and
10685 noticed how much had to change to get it operational using the
10686 university infrastructure. It was fairly easy, but it occured to me
10687 that Debian Edu would improve a lot if I could get the client to
10688 connect without any changes at all, and thus let the client configure
10689 itself during installation and first boot to use the infrastructure
10690 around it. Now I am a huge step further along that road.
</p
>
10692 <p
>With our current squeeze-test packages, I can select the roaming
10693 workstation profile and get a working laptop connecting to the
10694 university LDAP server for user and group and our active directory
10695 servers for Kerberos authentication. All this without any
10696 configuration at all during installation. My users home directory got
10697 a bookmark in the KDE menu to mount it via SMB, with the correct URL.
10698 In short, openldap and sssd is correctly configured. In addition to
10699 this, the client look for http://wpad/wpad.dat to configure a web
10700 proxy, and when it fail to find it no proxy settings are stored in
10701 /etc/environment and /etc/apt/apt.conf. Iceweasel and KDE is
10702 configured to look for the same wpad configuration and also do not use
10703 a proxy when at the university network. If the machine is moved to a
10704 network with such wpad setup, it would automatically use it when DHCP
10705 gave it a IP address.
</p
>
10707 <p
>The LDAP server is located using DNS, by first looking for the DNS
10708 entry ldap.$domain. If this do not exist, it look for the
10709 _ldap._tcp.$domain SRV records and use the first one as the LDAP
10710 server. Next, it connects to the LDAP server and search all
10711 namingContexts entries for posixAccount or posixGroup objects, and
10712 pick the first one as the LDAP base. For Kerberos, a similar
10713 algorithm is used to locate the LDAP server, and the realm is the
10714 uppercase version of $domain.
</p
>
10716 <p
>So, what is not working, you might ask. SMB mounting my home
10717 directory do not work. No idea why, but suspected the incorrect
10718 Kerberos settings in /etc/krb5.conf and /etc/samba/smb.conf might be
10719 the cause. These are not properly configured during installation, and
10720 had to be hand-edited to get the correct Kerberos realm and server,
10721 but SMB mounting still do not work. :(
</p
>
10723 <p
>With this automatic configuration in place, I expect a Debian Edu
10724 roaming profile installation would be able to automatically detect and
10725 connect to any site using LDAP and Kerberos for NSS directory and PAM
10726 authentication. It should also work out of the box in a Active
10727 Directory environment providing posixAccount and posixGroup objects
10728 with UID and GID values.

>The new roaming workstation profile in Debian Edu/Squeeze is fairly
10741 similar to the laptop setup am I working on using Ubuntu for the
10742 University of Oslo, and just for the heck of it, I tested today how
10743 hard it would be to integrate that profile into the university
10744 infrastructure. In this case, it is the university LDAP server,
10745 Active Directory Kerberos server and SMB mounting from the Netapp file
10748 <p
>I was pleasantly surprised that the only three files needed to be
10749 changed (/etc/sssd/sssd.conf, /etc/ldap.conf and
10750 /etc/mklocaluser.d/
20-debian-edu-config) and one file had to be added
10751 (/usr/share/perl5/Debian/Edu_Local.pm), to get the client working.
10752 Most of the changes were to get the client to use the university LDAP
10753 for NSS and Kerberos server for PAM, but one was to change a hard
10754 coded DNS domain name in the mklocaluser hook from .intern to
10757 <p
>This testing was so encouraging, that I went ahead and adjusted the
10758 Debian Edu scripts and setup in subversion to centralise the roaming
10759 workstation setup a bit more and avoid the hardcoded DNS domain name,
10760 so that when I test this tomorrow, I expect to get away with modifying
10761 only /etc/sssd/sssd.conf and /etc/ldap.conf to get it to use the
10762 university servers.
</p
>
10764 <p
>My goal is to get the clients to have no hardcoded settings and
10765 fetch all their initial setup during installation and first boot, to
10766 allow them to be inserted also into environments where the default
10767 setup in Debian Edu has been changed or as with the university, where

>The last few months me and the other Debian Edu developers have
10898 been working hard to get the Debian/Squeeze based version of Debian
10899 Edu/Skolelinux into shape. This future version will use Kerberos for
10900 authentication, and services are slowly migrated to single signon,
10901 getting rid of password questions one at the time.
</p
>
10903 <p
>It will also feature a roaming workstation profile with local home
10904 directory, for laptops that are only some times on the Skolelinux
10905 network, and for this profile a shortcut is created in Gnome and KDE
10906 to gain access to the users home directory on the file server. This
10907 shortcut uses SMB at the moment, and yesterday I had time to test if
10908 SMB mounting had started working in KDE after we added the cifs-utils
10909 package. I was pleasantly surprised how well it worked.
</p
>
10911 <p
>Thanks to the recent changes to our samba configuration to get it
10912 to use Kerberos for authentication, there were no question about user
10913 password when mounting the SMB volume. A simple click on the shortcut
10914 in the KDE menu, and a window with the home directory popped
10917 <p
>One step closer to a single signon solution out of the box in
10918 Debian Edu. We already had PAM, LDAP, IMAP and SMTP in place, and now
10919 also Samba. Next step is Cups and hopefully also NFS.
</p

10921 <p
>We had planned a alpha0 release of Debian Edu for today, but thanks
10922 to the autobuilder administrators for some architectures being slow to
10923 sign packages, we are still missing the fixed LTSP package we need for
10924 the release. It was uploaded three days ago with urgency=high, and if
10925 it had entered testing yesterday we would have been able to test it in
10926 time for a alpha0 release today. As the binaries for ia64 and powerpc
10927 still not uploaded to the Debian archive, we need to delay the alpha
10928 release another day.

10949 LDAP objects, I have had a look at how the packages pdns-backend-ldap

10964 One
"strict
" mode where the forward and reverse DNS lookups are done
10965 using the same LDAP objects, and a
"tree
" mode where the forward and
10966 reverse entries are in two different subtrees in LDAP with a structure
10967 based on the DNS names, as in tjener.intern and
10968 2.2.0.10.in-addr.arpa.
</p

10970 <p
>In tree mode, the server is set up to use a LDAP subtree as its
10971 base, and uses a

10,dc=in-addr,dc=arpa,
" with a filter for
10975 "(associateddomain=

10976 forward entries, it is looking for attributes named dnsttl, arecord,

11259 <description><p
>For a while now, I have wanted to find a way to change the DNS and
11260 DHCP services in Debian Edu to use the same LDAP objects for a given
11261 computer, to avoid the possibility of having a inconsistent state for
11262 a computer in LDAP (as in DHCP but no DNS entry or the other way
11263 around) and make it easier to add computers to LDAP.
</p
>
11265 <p
>I
've looked at how powerdns and dhcpd is using LDAP, and using this
11266 information finally found a solution that seem to work.
</p
>
11268 <p
>The old setup required three LDAP objects for a given computer.
11269 One forward DNS entry, one reverse DNS entry and one DHCP entry. If
11270 we switch powerdns to use its strict LDAP method (ldap-method=strict
11271 in pdns-debian-edu.conf), the forward and reverse DNS entries are
11272 merged into one while making it impossible to transfer the reverse map
11273 to a slave DNS server.
</p
>
11275 <p
>If we also replace the object class used to get the DNS related
11276 attributes to one allowing these attributes to be combined with the
11277 dhcphost object class, we can merge the DNS and DHCP entries into one.
11278 I
've written such object class in the dnsdomainaux.schema file (need
11279 proper OIDs, but that is a minor issue), and tested the setup. It
11280 seem to work.
</p
>
11282 <p
>With this test setup in place, we can get away with one LDAP object
11283 for both DNS and DHCP, and even the LTSP configuration I suggested in
11284 an earlier email. The combined LDAP object will look something like

</p

11305 <p

11306 dhcphost in a different location, to allow us to put the objects
11307 outside the

11308 that. If I can
't figure out a way to do that, we can still get rid of
11309 the hosts subtree and move all its content into the DHCP Config tree
11310 (which probably should be renamed to be more related to the new
11311 content. I suspect cn=dnsdhcp,ou=services or something like that
11312 might be a good place to put it.

>Vagrant mentioned on IRC today that ltsp_config now support
11325 sourcing files from /usr/share/ltsp/ltsp_config.d/ on the thin
11326 clients, and that this can be used to fetch configuration from LDAP if
11327 Debian Edu choose to store configuration there.
</p

11329 <p
>Armed with this information, I got inspired and wrote a test module
11330 to get configuration from LDAP. The idea is to look up the MAC
11331 address of the client in LDAP, and look for attributes on the form
11332 ltspconfigsetting=value, and use this to export SETTING=value to the
11333 LTSP clients.

11336 in a

11337 allowing us to store all information about a computer in one place.

11339 <p

11528 <description><p
>For a laptop, centralized user directories and password checking is
11529 a bit troubling. Laptops are typically used also when not connected
11530 to the network, and it is vital for a user to be able to log in or
11531 unlock the screen saver also when a central server is unavailable.
11532 This is possible by caching passwords and directory information (user
11533 and group attributes) locally, and the packages to do so are available
11534 in Debian. Here follow two recipes to set this up in Debian/Squeeze.
11535 It is also possible to set up in Debian/Lenny, but require more manual
11536 setup there because pam-auth-update is missing in Lenny.
</p
>
11538 <h2
>LDAP/Kerberos + nscd + libpam-ccreds + libpam-mklocaluser/pam_mkhomedir
</h2
>
11540 This is the traditional method with a twist. The password caching is
11541 provided by libpam-ccreds (version
10-
4 or later is needed on
11542 Squeeze), and the directory caching is done by nscd. The directory
11543 lookup and password checking is done using LDAP. If one want to use
11544 Kerberos for password checking the libpam-ldapd package can be
11545 replaced with libpam-krb5 or libpam-heimdal. If one is happy having a
11546 local home directory with the path listed in LDAP, one can use the
11547 pam_mkhomedir module from pam-modules to make this happen instead of
11548 using libpam-mklocaluser. A setup for pam-auth-update to enable
11549 pam_mkhomedir will have to be written until a fix for
11550 <a href=
"http://bugs.debian.org/
568577">bug #
568577</a
> is in the
11551 archive. Because I believe it is a bad idea to have local home
11552 directories using misleading paths like /site/server/partition/, I
11553 prefer to create a local user with the home directory in /home/. This
11554 is done using the libpam-mklocaluser package.

11670 libpam-ccreds. It support LDAP and Kerberos, but not NIS. Version
11671 1.2 do not support netgroups, but it is said that it will support this

11734 <description><p
>The last few days I have been looking into the status of the LDAP
11735 directory in Debian Edu, and in the process I started to miss a GUI
11736 tool to browse the LDAP tree. The only one I was able to find in
11737 Debian/Squeeze and Lenny is
11738 <a href=
"http://luma.sourceforge.net/
">LUMA
</a
>, which has proved to
11739 be a great tool to get a overview of the current LDAP directory
11740 populated by default in Skolelinux. Thanks to it, I have been able to
11741 find empty and obsolete subtrees, misplaced objects and duplicate
11742 objects. It will be installed by default in Debian/Squeeze. If you
11743 are working with LDAP, give it a go. :)
</p
>
11745 <p
>I did notice one problem with it I have not had time to report to
11746 the BTS yet. There is no .desktop file in the package, so the tool do
11747 not show up in the Gnome and KDE menus, but only deep down in in the
11748 Debian submenu in KDE. I hope that can be fixed before Squeeze is
11749 released.
</p
>
11751 <p
>I have not yet been able to get it to modify the tree yet. I would
11752 like to move objects and remove subtrees directly in the GUI, but have
11753 not found a way to do that with LUMA yet. So in the mean time, I use
11754 <a href=
"http://www.lichteblau.com/ldapvi/
">ldapvi
</a
> for that.
</p

11756 <p

11757 in Debian Edu, please contact us on debian-edu@lists.debian.org.

29: Ross Reedstrom tipped us about the
11760 <a href=
"http://packages.qa.debian.org/g/gq.html
">gq
</a
> package as a
11761 useful GUI alternative. It seem like a good tool, but is unmaintained
11762 in Debian and got a RC bug keeping it out of Squeeze. Unless that
11763 changes, it will not be an option for Debian Edu based on Squeeze.

11773 <a href=
"http://people.skolelinux.org/pere/blog/Time_for_new__LDAP_schemas_replacing_RFC_2307_.html
">complained
11774 about the fact
</a

11775 for storing DNS and DHCP information in LDAP to combine the two sets
11776 of information into one LDAP object representing a computer.
</p
>
11778 <p
>In the mean time, I discovered that a simple fix would be to make
11779 the dhcpHost object class auxiliary, to allow it to be combined with
11780 the dNSDomain object class, and thus forming one object for one
11781 computer when storing both DHCP and DNS information in LDAP.
</p

11783 <p
>If I understand this correctly, it is not safe to do this change
11784 without also changing the assigned number for the object class, and I
11785 do not know enough about LDAP schema design to do that properly for
11786 Debian Edu.

11824 of Debian upgrades
</a

've
11825 finally made the upgrade logs available from
11826 <a href=
"http://people.skolelinux.org/pere/debian-upgrade-testing/
">http://people.skolelinux.org/pere/debian-upgrade-testing/
</a
>.
11827 I am now testing dist-upgrade of Gnome and KDE in a chroot using both
11828 apt and aptitude, and found their differences interesting. This time
11829 I will only focus on their removal plans.
</p
>
11831 <p
>After installing a Gnome desktop and the laptop task, apt-get wants
11832 to remove
72 packages when dist-upgrading from Lenny to Squeeze. The
11833 surprising part is that it want to remove xorg and all
11834 xserver-xorg-video* drivers. Clearly not a good choice, but I am not
11835 sure why. When asking aptitude to do the same, it want to remove
129
11836 packages, but most of them are library packages I suspect are no
11837 longer needed. Both of them want to remove bluetooth packages, which
11838 I do not know. Perhaps these bluetooth packages are obsolete?
</p
>
11840 <p
>For KDE, apt-get want to remove
82 packages, among them kdebase
11841 which seem like a bad idea and xorg the same way as with Gnome. Asking
11842 aptitude for the same, it wants to remove
192 packages, none which are
11843 too surprising.
</p
>
11845 <p
>I guess the removal of xorg during upgrades should be investigated
11846 and avoided, and perhaps others as well. Here are the complete list
11847 of planned removals. The complete logs is available from the URL
11848 above. Note if you want to repeat these tests, that the upgrade test
11849 for kde+apt-get hung in the tasksel setup because of dpkg asking
11850 conffile questions. No idea why. I worked around it by using
11851 '<tt
>echo
>> /proc/
<em
>pidofdpkg
</em
>/fd/
0</tt
>' to tell dpkg to
11852 continue.

11998 <description><p
>The last few days I have done some upgrade testing in Debian, to
11999 see if the upgrade from Lenny to Squeeze will go smoothly. A few bugs
12000 have been discovered and reported in the process
12001 (
<a href=
"http://bugs.debian.org/
585410">#
585410</a
> in nagios3-cgi,
12002 <a href=
"http://bugs.debian.org/
584879">#
584879</a
> already fixed in
12003 enscript and
<a href=
"http://bugs.debian.org/
584861">#
584861</a
> in
12004 kdebase-workspace-data), and to get a more regular testing going on, I
12005 am working on a script to automate the test.
</p
>
12007 <p
>The idea is to create a Lenny chroot and use tasksel to install a
12008 Gnome or KDE desktop installation inside the chroot before upgrading
12009 it. To ensure no services are started in the chroot, a policy-rc.d
12010 script is inserted. To make sure tasksel believe it is to install a
12011 desktop on a laptop, the tasksel tests are replaced in the chroot
12012 (only acceptable because this is a throw-away chroot).
</p
>
12014 <p
>A naive upgrade from Lenny to Squeeze using aptitude dist-upgrade
12015 currently always fail because udev refuses to upgrade with the kernel
12016 in Lenny, so to avoid that problem the file /etc/udev/kernel-upgrade
12017 is created. The bug report
12018 <a href=
"http://bugs.debian.org/
566000">#
566000</a
> make me suspect
12019 this problem do not trigger in a chroot, but I touch the file anyway
12020 to make sure the upgrade go well. Testing on virtual and real
12021 hardware have failed me because of udev so far, and creating this file
12022 do the trick in such settings anyway. This is a
12023 <a href=
"http://www.linuxquestions.org/questions/debian-
26/failed-dist-upgrade-due-to-udev-config_sysfs_deprecated-nonsense-
804130/
">known
12024 issue
</a
> and the current udev behaviour is intended by the udev
12025 maintainer because he lack the resources to rewrite udev to keep
12026 working with old kernels or something like that. I really wish the
12027 udev upstream would keep udev backwards compatible, to avoid such
12028 upgrade problem, but given that they fail to do so, I guess
12029 documenting the way out of this mess is the best option we got for
12030 Debian Squeeze.

>Som systemarkitekten bak Skolelinux, kan jeg bare riste på hodet
12156 over påstanden om at Skolelinux krever desentraliserte tjenere.
12157 Skolelinux-arkitekturen er laget for sentralisert drift og plassering
12158 av tjenerne lokalt eller sentralt alt etter behov og nettkapasitet.
12159 Den er modellert på nettverks- og tjenerløsningen som brukes på
12160 Universitetet i Tromsø og Oslo, der jeg jobber med utvikling av
12161 driftstjenester. Dette er det heldigvis noen som har fått med seg, og
12162 jeg er glad for å kunne sitere fra en kommentar på den overnevnte
12163 artikkelen. Min venn og gamle kollega Sturle Sunde forteller der:
12166 <p
>I Flora kommune køyrer vi Skulelinux på skular med alt frå
15 til
12167 meir enn
500 elevar. Dei store skulane har eigen tenar, for det er
12168 mest praktisk. Eg, som er driftsansvarleg for heile nettet, ser
12169 sjeldan dei tenarane fysisk, men at dei står der gjer skulane mindre
12170 avhengige av eksterne linjer som er trege eller dyre. Dei minste
12171 skulane har ikkje eigen tenar. Å bruke sentral tenar er heller ikkje
12172 noko problem. Småskulane klarar seg fint med
1 mbit-linje til ein
12173 sentral tenar eller tenaren på ein større skule.
</p
>
12175 <p
>Det beste med Skulelinux er halvtjukke klientar. Dei treng ikkje
12176 harddisk og brukar minimalt med ressursar på tenaren fordi dei køyrer
12177 programma lokalt. Eit klasserom med
30 sju-åtte år gamle maskiner har
12178 mykje meir CPU og RAM totalt enn nokon moderne tenar til under
12179 millionen. Det trengst to kommandoar på den sentrale tenaren for å
12180 oppdatere alle klientane, både tynne og halvtjukke. Vi har ingen
12181 problem med diskar som ryk heller, som var eit problem før fordi
12182 elevane sat og sparka i maskinene. Og dei krev lite bandbreidde i
12183 nettet, so det er fullt mogleg å køyre slike på småskular med trege
12184 linjer mot tenaren på ein større skule.
</p
>
12186 <p
>Flora kommune har nesten
800 Linux-maskiner i sitt skulenett, og
12187 ein person som tek seg av drift av heile nettet, inkludert tenarar,
12188 klientar, operativsystem, programvare, heimekontorløysing og
12189 administrasjon av brukarar.

12191 <p
>No skal det seiast at vi ikkje køyrer rein Skulelinux ut av
12192 boksen. Vi har gjort ein del tilpassingar mot noko Novell-greier som
12193 var der frå før, og som har komplisert installasjonen vår. Etter at

12347 <p

12348 include some firmware packages on the Debian Edu CDs, those needed to
12349 get disk and network controllers working. Without having these
12350 firmware packages available during installation, it is impossible to
12351 install Debian Edu on the given machine, and because our target group
12352 are non-technical people, asking them to provide firmware packages on
12353 an external medium is a support pain. Initially, I expected it to be
12354 enough to include the firmware packages on the CD to get
12355 debian-installer to find and use them. This proved to be wrong.
12356 Next, I hoped it was enough to symlink the relevant firmware packages
12357 to some useful location on the CD (tried /cdrom/ and
12358 /cdrom/firmware/). This also proved to not work, and at this point I
12359 found time to look at the debian-installer code to figure out what was
12360 going to work.

12363 look revealed that it would only look for firmware packages outside
12364 the installation media, so the CD was never checked for firmware
12365 packages. It would only check USB sticks, floppies and other
12366 "external
" media devices. Today I changed it to also look in the
12367 /cdrom/firmware/ directory on the mounted CD or DVD, which should
12368 solve the problem I ran into with Debian edu. I also changed it to
12369 look in /firmware/, to make sure the installer also find firmware
12370 provided in the initrd when booting the installer via PXE, to allow us
12371 to provide the same feature in the PXE setup included in Debian
12374 <p
>To make sure firmware deb packages with a license questions are not
12375 activated without asking if the license is accepted, I extended
12376 hw-detect to look for preinst scripts in the firmware packages, and
12377 run these before activating the firmware during installation. The
12378 license question is asked using debconf in the preinst, so this should
12379 solve the issue for the firmware packages I have looked at so far.

12397 package needed by libpam-mklocaluser, and the
12398 <a href=
"http://packages.qa.debian.org/s/sssd.html
">sssd
</a

12399 passed NEW on Monday. In addition, the
12400 <a href=
"http://packages.qa.debian.org/libp/libpam-ccreds.html
">libpam-ccreds
</a
>
12401 package we need is in experimental (version
10-
4) since Saturday, and
12402 hopefully will be moved to unstable soon.
</p
>
12404 <p
>This collection of packages allow for two different setups for
12405 roaming laptops. The traditional setup would be using libpam-ccreds,
12406 nscd and libpam-mklocaluser with LDAP or Kerberos authentication,
12407 which should work out of the box if the configuration changes proposed
12408 for nscd in
<a href=
"http://bugs.debian.org/
485282">BTS report
12409 #
485282</a
> is implemented. The alternative setup is to use sssd with
12410 libpam-mklocaluser to connect to LDAP or Kerberos and let sssd take
12411 care of the caching of passwords and group information.
</p
>
12413 <p
>I have so far been unable to get sssd to work with the LDAP server
12414 at the University, but suspect the issue is some SSL/GnuTLS related
12415 problem with the server certificate. I plan to update the Debian
12416 package to version
1.2, which is scheduled for next week, and hope to
12417 find time to make sure the next release will include both the
12418 Debian/Ubuntu specific patches. Upstream is friendly and responsive,
12419 and I am sure we will find a good solution.
</p
>
12421 <p
>The idea is to set up the roaming laptops to authenticate using
12422 LDAP or Kerberos and create a local user with home directory in /home/
12423 when a usre in LDAP logs in via KDM or GDM for the first time, and
12424 cache the password for offline checking, as well as caching group
12425 memberhips and other relevant LDAP information. The
12426 libpam-mklocaluser package was created to make sure the local home
12427 directory is in /home/, instead of /site/server/directory/ which would
12428 be the home directory if pam_mkhomedir was used. To avoid confusion
12429 with support requests and configuration, we do not want local laptops
12430 to have users in a path that is used for the same users home directory
12431 on the home directory servers.
</p
>
12433 <p
>One annoying problem with gdm is that it do not show the PAM
12434 message passed to the user from libpam-mklocaluser when the local user
12435 is created. Instead gdm simply reject the login with some generic
12436 message. The message is shown in kdm, ssh and login, so I guess it is
12437 a bug in gdm. Have not investigated if there is some other message
12438 type that can be used instead to get gdm to also show the message.

12595 <description><p
>For some years now, I have wondered how we should handle laptops in
12596 Debian Edu. The Debian Edu infrastructure is mostly designed to
12597 handle stationary computers, and less suited for computers that come
12600 <p
>Now I finally believe I have an sensible idea on how to adjust
12601 Debian Edu for laptops, by introducing a new profile for them, for
12602 example called Roaming Workstations. Here are my thought on this.
12603 The setup would consist of the following:
</p
>
12607 <li
>During installation, the user name of the owner / primary user of
12608 the laptop is requested and a local home directory is set up for
12609 the user, with uid and gid information fetched from the LDAP
12610 server. This allow the user to work also when offline. The
12611 central home directory can be available in a subdirectory on
12612 request, for example mounted via CIFS. It could be mounted
12613 automatically when a user log in while on the Debian Edu network,
12614 and unmounted when the machine is taken away (network down,
12615 hibernate, etc), it can be set up to do automatic mounting on
12616 request (using autofs), or perhaps some GUI button on the desktop
12617 can be used to access it when needed. Perhaps it is enough to use
12618 the fish protocol in KDE?
</li
>
12620 <li
>Password checking is set up to use LDAP or Kerberos
12621 authentication when the machine is on the Debian Edu network, and
12622 to cache the password for offline checking when the machine unable
12623 to reach the LDAP or Kerberos server. This can be done using
12624 <a href=
"http://www.padl.com/OSS/pam_ccreds.html
">libpam-ccreds
</a
>
12625 or the Fedora developed
12626 <a href=
"https://fedoraproject.org/wiki/Features/SSSD
">System
12627 Security Services Daemon
</a
> packages.
</li
>
12629 <li
>File synchronisation with the central home directory is set up
12630 using a shared directory in both the local and the central home
12631 directory, using unison.
</li
>
12633 <li
>Printing should be set up to print to all printers broadcasting
12634 their existence on the local network, and should then work out of
12635 the box with CUPS. For sites needing accurate printer quotas, some
12636 system with Kerberos authentication or printing via ssh could be
12637 implemented.
</li
>
12639 <li
>For users that should have local root access to their laptop,
12640 sudo should be used to allow this to the local user.
</li
>
12642 <li
>It would be nice if user and group information from LDAP is
12643 cached on the client, but given that there are entries for the
12644 local user and primary group in /etc/, it should not be needed.
</li
>
12648 <p
>I believe all the pieces to implement this are in Debian/testing at
12649 the moment. If we work quickly, we should be able to get this ready
12650 in time for the Squeeze release to freeze. Some of the pieces need
12651 tweaking, like libpam-ccreds should get support for pam-auth-update
12652 (
<a href=
"http://bugs.debian.org/
566718">#
566718</a
>) and nslcd (or
12653 perhaps debian-edu-config) should get some integration code to stop
12654 its daemon when the LDAP server is unavailable to avoid long timeouts
12655 when disconnected from the net. If we get Kerberos enabled, we need
12656 to make sure we avoid long timeouts there too.

12669 NUUG presentation
</a
> about Kerberos was inspiring, and reminded me
12670 about the need to start using Kerberos in Skolelinux. Setting up a
12671 Kerberos server seem to be straight forward, and if we get this in
12672 place a long time before the Squeeze version of Debian freezes, we
12673 have a chance to migrate Skolelinux away from NFSv3 for the home
12674 directories, and over to an architecture where the infrastructure do
12675 not have to trust IP addresses and machines, and instead can trust
12676 users and cryptographic keys instead.
</p
>
12678 <p
>A challenge will be integration and administration. Is there a
12679 Kerberos implementation for Debian where one can control the
12680 administration access in Kerberos using LDAP groups? With it, the
12681 school administration will have to maintain access control using flat
12682 files on the main server, which give a huge potential for errors.
</p
>
12684 <p
>A related question I would like to know is how well Kerberos and
12685 pam-ccreds (offline password check) work together. Anyone know?
</p
>
12687 <p
>Next step will be to use Kerberos for access control in Lwat and
12688 Nagios. I have no idea how much work that will be to implement. We
12689 would also need to document how to integrate with Windows AD, as such
12690 shared network will require two Kerberos realms that need to cooperate
12691 to work properly.
</p
>
12693 <p
>I believe a good start would be to start using Kerberos on the
12694 skolelinux.no machines, and this way get ourselves experience with
12695 configuration and integration. A natural starting point would be
12696 setting up ldap.skolelinux.no as the Kerberos server, and migrate the
12697 rest of the machines from PAM via LDAP to PAM via Kerberos one at the
12700 <p
>If you would like to contribute to get this working in Skolelinux,
12701 I recommend you to see the video recording from yesterdays NUUG
12702 presentation, and start using Kerberos at home. The video show show
12703 up in a few days.

>6 years ago, as part of the Debian Edu development I am involved

12715 package in
2004 (
<a href=

12716 and revisited every time Debian Edu was working on a new release.
12717 Today, this finally paid off.

12719 <p

12720 repositry for the xorg package, and the git repository for xdm has
12721 been updated to use this framework. Next on my agenda is to make sure
12722 kdm and gdm also add code to use this framework.
</p

12724 <p
>In Debian Edu, we want to ability to run commands as root when the
12725 user log out, to get rid of runaway processes and do general cleanup
12726 after a user. With this framework in place, we finally can do that in
12727 a generic way that work with all display managers using this
12728 framework. My goal is to get all display managers in Debian use it,
12729 similar to how they use the Xsession.d framework today.

12750 the fixes we need into the official Debian packages before the freeze,

>One of the new features in the next Debian/Lenny based release of
12761 Debian Edu/Skolelinux, which is scheduled for release in the next few
12762 days, is automatic configuration of the service monitoring system
12763 Nagios. The previous release had automatic configuration of trend
12764 analysis using Munin, and this Lenny based release take that a step
12767 <p
>When installing a Debian Edu Main-server, it is automatically
12768 configured as a Munin and Nagios server. In addition, it is
12769 configured to be a server for the
12770 <a href=
"http://wiki.debian.org/DebianEdu/HowTo/SiteSummary
">SiteSummary
12771 system
</a
> I have written for use in Debian Edu. The SiteSummary
12772 system is inspired by a system used by the University of Oslo where I
12773 work. In short, the system provide a centralised collector of
12774 information about the computers on the network, and a client on each
12775 computer submitting information to this collector. This allow for
12776 automatic information on which packages are installed on each machine,
12777 which kernel the machines are using, what kind of configuration the
12778 packages got etc. This also allow us to automatically generate Munin
12779 and Nagios configuration.
</p
>
12781 <p
>All computers reporting to the sitesummary collector with the
12782 munin-node package installed is automatically enabled as a Munin
12783 client and graphs from the statistics collected from that machine show
12784 up automatically on http://www/munin/ on the Main-server.
</p
>
12786 <p
>All non-laptop computers reporting to the sitesummary collector are
12787 automatically monitored for network presence (ping and any network
12788 services detected). In addition, all computers (also laptops) with
12789 the nagios-nrpe-server package installed and configured the way
12790 sitesummary would configure it, are monitored for full disks, software
12791 raid status, swap free and other checks that need to run locally on
12792 the machine.
</p
>
12794 <p
>The result is that the administrator on a school using Debian Edu
12795 based on Lenny will be able to check the health of his installation
12796 with one look at the Nagios settings, without having to spend any time
12797 keeping the Nagios configuration up-to-date.
</p
>
12799 <p
>The only configuration one need to do to get Nagios up and running
12800 is to set the password used to get access via HTTP. The system
12801 administrator need to run
"<tt
>htpasswd /etc/nagios3/htpasswd.users
12802 nagiosadmin
</tt
>" to create a nagiosadmin user and set a password for
12803 it to be able to log into the Nagios web pages. After that,
12804 everything is taken care of.

"Teach the Teacher

12818 å få fri programvare og unix-lignende operativsystemer inn i Skolen.
12819 Tanken var at en måtte starte med lærerne for at ungene skulle få
12820 mulighet til å møte en bedre IT-hverdag. Jeg var tilstede på
12821 møtet, og hadde sans for ideen, men intet skjedde. På vårparten
12822 2001 ble det arrangert en demonstrasjon i anledning at First Tuesday
12823 hadde invitert Microsoft til et møte for å fortelle om fremtidens

12829 Etter demonstrasjonen arrangerte Håkon en fest hjemme hos seg der alle
12830 som hadde vært aktive i demonstrasjonsplanlegging og gjennomføringen
12831 deltok. Før festen var jeg blitt lei av å vente på at Håkon skulle ta
12832 initiativ til

12833 besteme jeg meg for å benytte anledningen hos Håkon til å snakke om
12834 behovet for å hjelpe skolene i gang med bedre datasystemer bestående
12835 av fri programvare og unix-lignende operativsystemer. Flere var
12836 interessert, og Knut Yrvin tenkte på ideen. Han

>I
'm sitting on the train going home from this weekends Debian
12874 Edu/Skolelinux development gathering. I got a bit done tuning the
12875 desktop, and looked into the dynamic service location protocol
12876 implementation avahi. It look like it could be useful for us. Almost
12877 30 people participated, and I believe it was a great environment to
12878 get to know the Skolelinux system. Walter Bender, involved in the
12879 development of the Sugar educational platform, presented his stuff and
12880 also helped me improve my OLPC installation. He also showed me that
12881 his Turtle Art application can be used in standalone mode, and we
12882 agreed that I would help getting it packaged for Debian. As a
12883 standalone application it would be great for Debian Edu. We also
12884 tried to get the video conferencing working with two OLPCs, but that
12885 proved to be too hard for us. The application seem to need more work
12886 before it is ready for me. I look forward to getting home and relax

>The state of standardized LDAP schemas on Linux is far from
12897 optimal. There is RFC
2307 documenting one way to store NIS maps in
12898 LDAP, and a modified version of this normally called RFC
2307bis, with
12899 some modifications to be compatible with Active Directory. The RFC
12900 specification handle the content of a lot of system databases, but do
12901 not handle DNS zones and DHCP configuration.

12904 we would like to store information about users, SMB clients/hosts,
12905 filegroups, netgroups (users and hosts), DHCP and DNS configuration,
12906 and LTSP configuration in LDAP. These objects have a lot in common,
12907 but with the current LDAP schemas it is not possible to have one
12908 object per entity. For example, one need to have at least three LDAP
12909 objects for a given computer, one with the SMB related stuff, one with
12910 DNS information and another with DHCP information. The schemas
12911 provided for DNS and DHCP are impossible to combine into one LDAP
12912 object. In addition, it is impossible to implement quick queries for
12913 netgroup membership, because of the way NIS triples are implemented.
12914 It just do not scale. I believe it is time for a few RFC
12915 specifications to cleam up this mess.

12918 the network, and this object can then keep the SMB (ie host key), DHCP

12920 It need to be efficently stored to make sure it scale well.

</a

12959 endelig første juledag. Bruken av bindestrek som ordskillemarkør har
12960 gjort det umulig å få med ord med bindestrek i
12961 stavekontrolldatagrunnlaget, slik at ord som e-post og CD-spiller ikke
12962 kunne godtas av stavekontrollen. Hadde litt tid til overs å bruke på
12963 stavekontrollen, og satte meg ned med to kopier av byggsystemet og en
12964 liten testdatafil, og byttet ut - med = på utvalgte steder i
12965 byggsystemet og datafilen helt til jeg fikk samme resultat med det
12966 gamle og det nye byggsystemet. Dette tror jeg var forsøk
4, der de
12967 foregående har feilet uten at jeg klarte å forstå hvorfor. Det sier
12968 kanskje litt om kompleksiteten i det originale byggsystemet som Rune
12969 Kleveland laget i sin tid.

>Recently I have spent some time evaluating the multimedia browser
13010 plugins available in Debian Lenny, to see which one we should use by
13011 default in Debian Edu. We need an embedded video playing plugin with
13012 control buttons to pause or stop the video, and capable of streaming
13013 all the multimedia content available on the web. The test results and
13014 notes are available on
13015 <a href=

13016 Debian wiki

13017 fill this need. My personal video player favorite, VLC, has a really
13018 bad plugin which fail on a lot of the test pages. A lot of the MIME
13019 types I would expect to work with any free software player (like
13020 video/ogg), just do not work. And simple formats like the
13021 audio/x-mplegurl format (m3u playlists), just isn
't supported by the
13022 totem and vlc plugins. I hope the situation will improve soon. No
13023 wonder sites use the proprietary Adobe flash to play video.
