>The
<a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
15 project
</a
> provide a Linux solution for schools, including a
16 powerful desktop with education software, a central server providing
17 web pages, user database, user home directories, central login and PXE
18 boot of both clients without disk and the installation to install Debian
19 Edu on machines with disk (and a few other services perhaps to small
20 to mention here). We in the Debian Edu team are currently working on
21 the Jessie based version, trying to get everything in shape before the
22 freeze, to avoid having to maintain our own package repository in the
24 <a href=
"https://wiki.debian.org/DebianEdu/Status/Jessie
">current
25 status
</a
> can be seen on the Debian wiki, and there is still heaps of
26 work left. Some fatal problems block testing, breaking the installer,
27 but it is possible to work around these to get anyway. Here is a
28 recipe on how to get the installation limping along.
</p
>
30 <p
>First, download the test ISO via
31 <a href=
"ftp://ftp.skolelinux.no/cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-
1.iso
">ftp
</a
>,
32 <a href=
"http://ftp.skolelinux.no/cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-
1.iso
">http
</a
>
34 ftp.skolelinux.org::cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-
1.iso).
35 The ISO build was broken on Tuesday, so we do not get a new ISO every
36 12 hours or so, but thankfully the ISO we got is able to install with
37 some tweaking.
</p
>
39 <p
>When you get to the Debian Edu profile question, go to tty2
40 (use Alt-Ctrl-F2), run
</p
>
42 <p
><blockquote
><pre
>
43 nano /usr/bin/edu-eatmydata-install
44 </pre
></blockquote
></p
>
46 <p
>and add
'exit
0' as the second line, disabling the eatmydata
47 optimization. Return to the installation, select the profile you want
48 and continue. Without this change, exim4-config will fail to install
49 due to a known bug in eatmydata.
</p
>
51 <p
>When you get the grub question at the end, answer /dev/sda (or if
52 this do not work, figure out what your correct value would be. All my
53 test machines need /dev/sda, so I have no advice if it do not fit
56 <p
>If you installed a profile including a graphical desktop, log in as
57 root after the initial boot from hard drive, and install the
58 education-desktop-XXX metapackage. XXX can be kde, gnome, lxde, xfce
59 or mate. If you want several desktop options, install more than one
60 metapackage. Once this is done, reboot and you should have a working
61 graphical login screen. This should no longer be needed once the
62 education-tasks package version
1.801 enter testing in two days.
</p
>
64 <p
>I believe the ISO build will start working on two days when the new
65 tasksel package enter testing and Steve McIntyre get a chance to
66 update the debian-cd git repository. The eatmydata, grub and desktop
67 issues are already fixed in unstable and testing, and should show up
68 on the ISO as soon as the ISO build start working again. Well the
69 eatmydata optimization is really just disabled. The proper fix
70 require an upload by the eatmydata maintainer applying the patch
71 provided in bug
<a href=
"https://bugs.debian.org/
702711">#
702711</a
>.
72 The rest have proper fixes in unstable.
</p
>
74 <p
>I hope this get you going with the installation testing, as we are
75 quickly running out of time trying to get our Jessie based
76 installation ready before the distribution freeze in a month.

85 <description><p
>The
<a href=
"https://www.debian.org/
">Debian
</a
> installer could be
86 a lot quicker. When we install more than
2000 packages in
87 <a href=
"http://www.skolelinux.org/
">Skolelinux / Debian Edu
</a
> using
88 tasksel in the installer, unpacking the binary packages take forever.
89 A part of the slow I/O issue was discussed in
90 <a href=
"https://bugs.debian.org/
613428">bug #
613428</a
> about too
91 much file system sync-ing done by dpkg, which is the package
92 responsible for unpacking the binary packages. Other parts (like code
93 executed by postinst scripts) might also sync to disk during
94 installation. All this sync-ing to disk do not really make sense to
95 me. If the machine crash half-way through, I start over, I do not try
96 to salvage the half installed system. So the failure sync-ing is
97 supposed to protect against, hardware or system crash, is not really
98 relevant while the installer is running.
</p
>
100 <p
>A few days ago, I thought of a way to get rid of all the file
101 system sync()-ing in a fairly non-intrusive way, without the need to
102 change the code in several packages. The idea is not new, but I have
103 not heard anyone propose the approach using dpkg-divert before. It
104 depend on the small and clever package
105 <a href=
"https://packages.qa.debian.org/eatmydata
">eatmydata
</a
>, which
106 uses LD_PRELOAD to replace the system functions for syncing data to
107 disk with functions doing nothing, thus allowing programs to live
108 dangerous while speeding up disk I/O significantly. Instead of
109 modifying the implementation of dpkg, apt and tasksel (which are the
110 packages responsible for selecting, fetching and installing packages),
111 it occurred to me that we could just divert the programs away, replace
112 them with a simple shell wrapper calling
113 "eatmydata
&nbsp;$program
&nbsp;$@
", to get the same effect.
114 Two days ago I decided to test the idea, and wrapped up a simple
115 implementation for the Debian Edu udeb.
</p
>
117 <p
>The effect was stunning. In my first test it reduced the running
118 time of the pkgsel step (installing tasks) from
64 to less than
44
119 minutes (
20 minutes shaved off the installation) on an old Dell
120 Latitude D505 machine. I am not quite sure what the optimised time
121 would have been, as I messed up the testing a bit, causing the debconf
122 priority to get low enough for two questions to pop up during
123 installation. As soon as I saw the questions I moved the installation
124 along, but do not know how long the question were holding up the
125 installation. I did some more measurements using Debian Edu Jessie,
126 and got these results. The time measured is the time stamp in
127 /var/log/syslog between the
"pkgsel: starting tasksel
" and the
128 "pkgsel: finishing up
" lines, if you want to do the same measurement
129 yourself. In Debian Edu, the tasksel dialog do not show up, and the
130 timing thus do not depend on how quickly the user handle the tasksel

179 <p
>The test is done using a netinst ISO on a USB stick, so some of the
180 time is spent downloading packages. The connection to the Internet
181 was
100Mbit/s during testing, so downloading should not be a
182 significant factor in the measurement. Download typically took a few
183 seconds to a few minutes, depending on the amount of packages being
186 <p
>The speedup is implemented by using two hooks in
187 <a href=
"https://www.debian.org/devel/debian-installer/
">Debian
188 Installer
</a
>, the pre-pkgsel.d hook to set up the diverts, and the
189 finish-install.d hook to remove the divert at the end of the
190 installation. I picked the pre-pkgsel.d hook instead of the
191 post-base-installer.d hook because I test using an ISO without the
192 eatmydata package included, and the post-base-installer.d hook in
193 Debian Edu can only operate on packages included in the ISO. The
194 negative effect of this is that I am unable to activate this
195 optimization for the kernel installation step in d-i. If the code is
196 moved to the post-base-installer.d hook, the speedup would be larger
197 for the entire installation.

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

273 <p

274 Debian installer too? I suspect it should, but am not sure the
275 current debian-installer coordinators find it useful enough. It also
276 depend on the side effects of the change. I
'm not aware of any, but I
277 guess we will see if the change is safe after some more testing.
278 Perhaps there is some package in Debian depending on sync() and
279 fsync() having effect? Perhaps it should go into its own udeb, to
280 allow those of us wanting to enable it to do so without affecting

>Update
2014-
09-
24: Since a few days ago, enabling this optimization
284 will break installation of all programs using gnutls because of

30 years in this job.
30 years ago I started to
307 support my wife and become her officeworker and a few years later the
308 administrator for a small computer network, today based on Ubuntu
309 Server (Samba, OpenVPN). For her daily work she has to use Windows
310 Desktops because the software she needs to organize her business only

315 Linux server with
6 Windows clients and
10 persons (teacher of
316 children with special needs, speech therapist, occupational therapist,
317 psychologist and officeworkers) using our Samba shares via OpenVPN to

324 his school (
<a href=
"http://www.gymnasium-harsewinkel.de/

336 <p
>First: Every person is allowed to use, share and develop the
337 software. Even if you are poor, you are allowed to use the software
338 included in Skolelinux/Debian Edu and all the other Free Software.
</p

340 <p

348 terminal server. In the moment we are installing
30 laptops as mobile
349 workstations. Then the pupils have the possibility to work with these

385 project
</a
> provide an instruction manual for teachers, system
386 administrators and other users that contain useful tips for setting up
387 and maintaining a Debian Edu installation. This text is about how the
388 text processing of this manual is handled in the project.
</p
>
390 <p
>One goal of the project is to provide information in the native
391 language of its users, and for this we need to handle translations.
392 But we also want to make sure each language contain the same
393 information, so for this we need a good way to keep the translations
394 in sync. And we want it to be easy for our users to improve the
395 documentation, avoiding the need to learn special formats or tools to
396 contribute, and the obvious way to do this is to make it possible to
397 edit the documentation using a web browser. We also want it to be
398 easy for translators to keep the translation up to date, and give them
399 help in figuring out what need to be translated. Here is the list of
400 tools and the process we have found trying to reach all these
403 <p
>We maintain the authoritative source of our manual in the
404 <a href=
"https://wiki.debian.org/DebianEdu/Documentation/Wheezy/
">Debian
405 wiki
</a
>, as several wiki pages written in English. It consist of one
406 front page with references to the different chapters, several pages
407 for each chapter, and finally one
"collection page
" gluing all the
408 chapters together into one large web page (aka
409 <a href=
"https://wiki.debian.org/DebianEdu/Documentation/Wheezy/AllInOne
">the
410 AllInOne page
</a
>). The AllInOne page is the one used for further
411 processing and translations. Thanks to the fact that the
412 <a href=
"http://moinmo.in/
">MoinMoin
</a
> installation on
413 wiki.debian.org support exporting pages in
414 <a href=
"http://www.docbook.org/
">the Docbook format
</a
>, we can fetch
415 the list of pages to export using the raw version of the AllInOne
416 page, loop over each of them to generate a Docbook XML version of the
417 manual. This process also download images and transform image
418 references to use the locally downloaded images. The generated
419 Docbook XML files are slightly broken, so some post-processing is done
420 using the
<tt
>documentation/scripts/get_manual
</tt
> program, and the
421 result is a nice Docbook XML file (debian-edu-wheezy-manual.xml) and
422 a handfull of images. The XML file can now be used to generate PDF, HTML
423 and epub versions of the English manual. This is the basic step of
424 our process, making PDF (using dblatex), HTML (using xsltproc) and
425 epub (using dbtoepub) version from Docbook XML, and the resulting files
426 are placed in the debian-edu-doc-en binary package.
</p
>
428 <p
>But English documentation is not enough for us. We want translated
429 documentation too, and we want to make it easy for translators to
430 track the English original. For this we use the
431 <a href=
"http://packages.qa.debian.org/p/poxml.html
">poxml
</a
> package,
432 which allow us to transform the English Docbook XML file into a
433 translation file (a .pot file), usable with the normal gettext based
434 translation tools used by those translating free software. The pot
435 file is used to create and maintain translation files (several .po
436 files), which the translations update with the native language
437 translations of all titles, paragraphs and blocks of text in the
438 original. The next step is combining the original English Docbook XML
439 and the translation file (say debian-edu-wheezy-manual.nb.po), to
440 create a translated Docbook XML file (in this case
441 debian-edu-wheezy-manual.nb.xml). This translated (or partly
442 translated, if the translation is not complete) Docbook XML file can
443 then be used like the original to create a PDF, HTML and epub version
444 of the documentation.
</p
>
446 <p
>The translators use different tools to edit the .po files. We
448 <a href=
"http://www.kde.org/applications/development/lokalize/
">lokalize
</a
>,
449 while some use emacs and vi, others can use web based editors like
450 <a href=
"http://pootle.translatehouse.org/
">Poodle
</a
> or
451 <a href=
"https://www.transifex.com/
">Transifex
</a
>. All we care about
452 is where the .po file end up, in our git repository. Updated
453 translations can either be committed directly to git, or submitted as
454 <a href=
"https://bugs.debian.org/src:debian-edu-doc
">bug reports
455 against the debian-edu-doc package
</a
>.
</p
>
457 <p
>One challenge is images, which both might need to be translated (if
458 they show translated user applications), and are needed in different
459 formats when creating PDF and HTML versions (epub is a HTML version in
460 this regard). For this we transform the original PNG images to the
461 needed density and format during build, and have a way to provide
462 translated images by storing translated versions in
463 images/$LANGUAGECODE/. I am a bit unsure about the details here. The
464 package maintainers know more.

466 <p

467 <a href=
"http://maintainer.skolelinux.org/debian-edu-doc/

468 of the documentation packages on the web

491 keep gaining new users. Some weeks ago, a person showed up on IRC,
492 <a href=
"irc://irc.debian.org/#debian-edu
">#debian-edu
</a
>, with a
493 wish to contribute, and I managed to get a interview with this great
494 contributor Roger Marsal to learn more about his background.
</p
>
496 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
498 <p
>My name is Roger Marsal, I
'm
27 years old (
1986 generation) and I
499 live in Barcelona, Spain. I
've got a strong business background and I
500 work as a patrimony manager and as a real estate agent. Additionally,
501 I
've co-founded a British based tech company that is nowadays on the
502 last development phase of a new social networking concept.
</p
>
504 <p
>I
'm a Linux enthusiast that started its journey with Ubuntu four years
505 ago and have recently switched to Debian seeking rock solid stability
506 and as a necessary step to gain expertise.
</p
>
508 <p
>In a nutshell, I spend my days working and learning as much as I
509 can to face both my job, entrepreneur project and feed my Linux
512 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
513 project?
</strong
></p
>
515 <p
>I discovered the
<a href=
"http://www.ltsp.org/
">LTSP
</a
> advantages
516 with
"Ubuntu
12.04 alternate install
" and after a year of use I
517 started looking for an alternative. Even though I highly value and
518 respect the Ubuntu project, I thought it was necessary for me to
519 change to a more robust and stable alternative. As far as I was using
520 Debian on my personal laptop I thought it would be fine to install
521 Debian and configure an LTSP server myself. Surprised, I discovered
522 that the Debian project also supported a kind of Edubuntu equivalent,
523 and after having some pain I obtained a Debian Edu network up and
524 running. I just loved it.
</p
>
526 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
527 Edu?
</strong
></p
>
529 <p
>I found a main advantage in that, once you know
"the tips and
530 tricks
", a new installation just works out of the box. It
's the most
531 complete alternative I
've found to create an LTSP network. All the
532 other distributions seems to be made of plastic, Debian Edu seems to
533 be made of steel.
</p
>
535 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
536 Edu?
</strong
></p
>
538 <p
>I found two main disadvantages.
</p
>
540 <p
>I
'm not an expert but I
've got notions and I had to spent a considerable
541 amount of time trying to bring up a standard network topology. I
'm quite
542 stubborn and I just worked until I did but I
'm sure many people with few
543 resources (not big schools, but academies for example) would have switched
544 or dropped.
</p
>
546 <p
>It
's amazing how such a complex system like Debian Edu has achieved
547 this out-of-the-box state. Even though tweaking without breaking gets
548 more difficult, as more factors have to be considered. This can
549 discourage many people too.
</p
>
551 <p
><strong
>Which free software do you use daily?
</strong
></p
>
553 <p
>I use Debian, Firefox, Okular, Inkscape, LibreOffice and
554 Virtualbox.
</p
>
557 <p
><strong
>Which strategy do you believe is the right one to use to
558 get schools to use free software?
</strong
></p
>
560 <p
>I don
't think there is a need for a particular strategy. The free
561 attribute in both
"freedom
" and
"no price
" meanings is what will
562 really bring free software to schools. In my experience I can think of
563 the
<a href=
"http://www.r-project.org/
">"R
" statistical language
</a
>; a
564 few years a ago was an extremely nerd tool for university people.
565 Today it
's being increasingly used to teach statistics at many
566 different level of studies. I believe free and open software will
567 increasingly gain popularity, but I
'm sure schools will be one of the
568 first scenarios where this will happen.

>On larger sites, it is useful to use a dedicated storage server for
578 storing user home directories and data. The design for handling this
579 in
<a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>, is
580 to update the automount rules in LDAP and let the automount daemon on
581 the clients take care of the rest. I was reminded about the need to
582 document this better when one of the customers of
583 <a href=
"http://www.slxdrift.no/
">Skolelinux Drift AS
</a
>, where I am
584 on the board of directors, asked about how to do this. The steps to
585 get this working are the following:
</p
>
589 <li
>Add new storage server in DNS. I use nas-server.intern as the
590 example host here.
</li
>
592 <li
>Add automoun LDAP information about this server in LDAP, to allow
593 all clients to automatically mount it on reqeust.
</li
>
595 <li
>Add the relevant entries in tjener.intern:/etc/fstab, because
596 tjener.intern do not use automount to avoid mounting loops.
</li
>
598 </ol
></p
>
600 <p
>DNS entries are added in GOsa², and not described here. Follow the
601 <a href=
"https://wiki.debian.org/DebianEdu/Documentation/Wheezy/GettingStarted
">instructions
602 in the manual
</a
> (Machine Management with GOsa² in section Getting
605 <p
>Ensure that the NFS export points on the server are exported to the
606 relevant subnets or machines:

609 root@tjener:~# showmount -e nas-server
610 Export list for nas-server:

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

625 ldapvi --ldap-conf -ZD

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

650 <p

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

</p

654 <p
>When this is done, your users should be able to access the files on
655 the storage server directly by just visiting the

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

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

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

695 <p
>That said, one might see me as a kind of
"glue
" between school kids
696 and the elderly of teachers as well as between the open source
697 ecosystem and the (even more complex) educational ecosystem.
</p
>
699 <p
>When I am not busy with open source or education, I like Geocaching
700 and cycling.
</p
>
702 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
703 project?
</strong
></p
>
705 <p
>I think that happened some time around
2009 when I first attended
706 <a href=
"http://www.froscon.org
">FrOSCon
</a
> and visited the project
707 booth. I think I wasn
't too interested back then because I used to
708 have an attitude of disliking software that does too much stuff on its
709 own. Maybe I was too inexperienced to realise the upsides of an
710 "out-of-the-box
" solution ;).
</p
>
712 <p
>The first time I actively talked to Skolelinux people was at
713 <a href=
"http://www.openrheinruhr.de
">OpenRheinRuhr
</a
> 2011 when the
714 BiscuIT project, a home-grewn software used by my school for various
715 really cool things from timetables and class contact lists to lunch
716 ordering, student ID card printing and project elections first got to
717 a stage where it could have been published. I asked the Skolelinux
718 guys running the booth if the project were interested in it and gave a
719 small demonstration, but there wasn
't any real feedback and the guys
720 seemed rather uninterested.
</p
>
722 <p
>After I left the school where I developed the software, it got
723 mostly lost, but I am now reimplementing it for my new school. I have
724 reusability and compatibility in mind, and I hop there will be a new
725 basis for contributing it to the Skolelinux project ;)!
</p
>
727 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
728 Edu?
</strong
></p
>
730 <p
>The most important advantage seems to be that it
"just
731 works
". After overcoming some minor (but still very annoying) glitches
732 in the installer, I got a fully functional, working school network,
733 without the month-long hassle I experienced when setting all that up
734 from scratch in earlier years. And above that, it rocked - I didn
't
735 have any real hardware at hand, because the school was just founded
736 and has no money whatsoever, so I installed a combined server (main
737 server, terminal services and workstation) in a VM on my personal
738 notebook, bridging the LTSP network interface to the ethernet port,
739 and then PXE-booted the Windows notebooks that were lying around from
740 it. I could use
8 clients without any performance issues, by using a
741 tiny little VM on a tiny little notebook. I think that
's enough to say
742 that it rocks!
</p
>
744 <p
>Secondly, there are marketing reasons. Life
's bad, and so no
745 politician will ever permit a setup described as
"Debian, an universal
746 operating system, with some really cool educational tools
" while they
747 will be jsut fine with
"Skolelinux, a single-purpose solution for your
748 school network
", even if both turn out to be the very same thing (yes,
749 this is unfair towards the Skolelinux project, and must not be taken
750 too seriously - you get the idea, anyway).
</p
>
752 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
753 Edu?
</strong
></p
>
755 <p
>I have not been involved with Skolelinux long enough to really
756 answer this question in a fair way. Thus, please allow me to put it in
757 other words:
"What do you expect from Skolelinux to keep liking it?
" I
758 can list a few points about that:
</p
>
762 <li
>always strive to get all things integrated into Debian upstream
763 <li
>be open to discussion about changes and the like, even with newcomers
764 <li
>be helpful at being helpful ;)

>I
'm really sorry I cannot say much more about that :(!
</p
>
770 <p
><strong
>Which free software do you use daily?
</strong
></p
>
772 <p
>First of all, all software I use is free and open. I have abandoned
773 all non-free software (except for firmware on my darned phone) this
776 <p
>I run Debian GNU/Linux on all PC systems I use. On that, I mostly
777 run text tools. I use
778 <a href=
"https://www.mirbsd.org/mksh.htm
">mksh
</a
> as shell,
779 <a href=
"https://www.mirbsd.org/jupp.htm
">jupp
</a
> as very advanced
780 text editor (I even got the developer to help me write a script/macro
781 based full-featured student management software with the two),
782 <a href=
"http://mcabber.com/
">mcabber
</a
> for XMPP and
783 <a href=
"http://www.irssi.org/
">irssi
</a
> for IRC. For that overly
784 coloured world called the WWW, I use
785 <a href=
"https://www.mozilla.org/en-US/firefox/new/
">Iceweasel
786 (Firefox)
</a
>. Oh, and
<a href=
"http://www.mutt.org/
">mutt
</a
> for
789 <p
>However, while I am personally aware of the fact that text tools
790 are more efficient and powerful than anything else, I also use (or at
791 least operate) some tools that are suitable to bring open source to
792 kids. One of these things is
<a href=
"http://jappix.org/
">Jappix
</a
>,
793 which I already introduced to some kids even before they got aware of
794 Facebook, making them see for themselves that they do not need
795 Facebook now ;).
</p
>
797 <p
><strong
>Which strategy do you believe is the right one to use to
798 get schools to use free software?
</strong
></p
>
800 <p
>Well, that
's a two-sided thing. One side is what I believe, and one
801 side is what I have experienced.
</p
>
803 <p
>I believe that the right strategy is showing them the benefits. But
804 that won
't work out as long as the acceptance of free alternatives
805 grows globally. What I mean is that if all the kids are almost forced
806 to use Windows, Facebook, Skype, you name it at home, they will not
807 see why they would want to use alternatives at school. I have seen
808 students take seat in front of a fully-functional, modern Debian
809 desktop that could do anything their Windows at home could do, and
810 they jsut refused to use it because
"Linux sucks
". It is something
811 that makes the council of our city spend around
600000 € to buy
812 software - not including hardware, mind you - for operating school
813 networks, and for installing a system that, as has been proved, does
814 not work. For those of you readers who are good at maths, have you
815 already found out how many lives could have been saved with that money
816 if we had instead used it to bring education to parts of the world
817 that need it? I have, and found it to be nothing less dramatic than
818 plain criminal.
</p
>
820 <p
>That said, the only feasible way appears to be the bottom up
821 method. We have to bring free software to kids and parents. I have
822 founded an association named
823 <a href=
"https://www.teckids.org
">Teckids
</a
> here in Germany that does
824 just that. We organise several events for kids and adolescents in the
825 area of free and open source software, for example the
826 <a href=
"http://kids.froscon.org
">FrogLabs
</a
>, which share staff with
827 Teckids and are the youth programme of
828 <a href=
"http://www.froscon.org
">the Free and Open Source Software
829 Conference (FrOSCon)
</a
>. We do a lot more than most other conferences
830 - this year, we first offered the FrogLabs as a holiday camp for kids
831 aged
10 to
16. It was a huge success, with approx.
30 kids taking part
832 and learning with and about free software through a whole weekend. All
833 of us had a lot of fun, and the results were really exciting.
</p
>
835 <p
>Apart from that, we are preparing a campaign that is supposed to bring
836 the message of free alternatives to stuff kids use every day to them and
837 their parents, e.g. the use of Jabber / Jappix instead of Facebook and
838 Skype. To make that possible, we are planning to get together a team of
839 clever kids who understand very well what their peers need and can bring
840 it across to them. So we will have a peer-driven network of adolescents
841 who teach each other and collect feedback from the community of minors.
842 We then take that feedback and our own experience to work closely with
843 open source projects, such as Skolelinux or Jappix, at improving their
844 software in a way that makes it more and more attractive for the target
845 group. At least I hope that we will have good cooperation with
846 Skolelinux in the future ;)!
</p
>
848 <p
>So in conclusion, what I believe is that, if it weren
't for the world
849 being so bad, it should be very clear to the political decision makers
850 that the only way to go nowadays is free software for various reasons,
851 but I have learnt that the only way that seems to work is bottom up.
</p
>
855 > * Who should be interviewed with this questions in the future?
857 That
's probably the hardest question of them all, as I do not know the
858 community. However, I would be willing to do the following:
860 <li

878 but the
<a href=

880 had a new school administrator show up on

</a

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

889 <p
>I am Klaus Knopper. I have a master degree in electrical
890 engineering, and is currently professor in information management at
891 the university of applied sciences Kaiserslautern / Germany and
892 freelance Open Source software developer and consultant.
</p

894 <p
>All of this is pretty much of the work I spend my days with. Apart
895 from teaching, I
'm also conducting some more or less experimental
896 projects like the

904 <p

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

912 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
913 Edu?
</strong
></p
>
916 <li
>Quick installation,
</li

917 <li

</li
>
918 <li
>contains many useful software packages for teaching and learning,
</li
>
919 <li
>is a purely community-based distro and not controlled by a
920 single company,
</li
>
921 <li
>has a large number of supporters and teachers who share their
922 experience and problem solutions.
</li
>
925 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
926 Edu?
</strong
></p
>
929 <li
>Skolelinux is - as we had to learn - not easily upgradable to
930 the next version. Opposed to its genuine Debian base, upgrading to
931 a new version means a full new installation from scratch to get it
932 working again reliably.
934 <li
>Skolelinux is based on Debian/stable, and therefore always a
935 little outdated in terms of program versions compared to Edubuntu or
936 similar educational Linux distros, which rather use Debian/testing
939 <li
>Skolelinux has some very self-opinionated and stubborn default
940 configuration which in my opinion adds unnecessary complexity and is
941 not always suitable for a schools needs, the preset network
942 configuration is actually a core definition feature of Skolelinux
943 and not easy to change, so schools sometimes have to change their
944 network configuration to make it
"Skolelinux-compatible
".
946 <li
>Some proposed extensions, which were made available as
947 contribution, like secure examination mode and lecture material
948 distribution and collection, were not accepted into the mainline
949 Skolelinux development and are now not easy to maintain in the
950 future because of Skolelinux somewhat undeterministic update
953 <li
>Skolelinux has only a very tiny number of base developers
954 compared to Debian.
</li
>
958 <p
>For these reasons and experience from our project, I would now
959 rather consider using plain Debian for schools next time, until
960 Skolelinux is more closely integrated into Debian and becomes
961 upgradeable without reinstallation.
</p
>
963 <p
><strong
>Which free software do you use daily?
</strong
></p
>
965 <p
>GNU/Linux with LXDE desktop, bash for interactive dialog and
966 programming, texlive for documentation and correspondence,
967 occasionally LibreOffice for document format conversion. Various
968 programming languages for teaching.
</p
>
970 <p
><strong
>Which strategy do you believe is the right one to use to
971 get schools to use free software?
</strong
></p
>
973 <p
>Strong arguments are
</p
>
977 <li
>Knowledge is free, and so should be methods and tools for
978 teaching and learning.
</li
>
980 <li
>Students can learn with and use the same software at school, at
981 home, and at their working place without running into license or
982 conversion problems.
</li
>
984 <li
>Closed source or proprietary software hides knowledge rather
985 than exposing it, and proprietary software vendors try to bind
986 customers to certain products. But teachers need to teach
987 science, not products.
</li
>
989 <li
>If you have everything you for daily work as open source, what
990 would you need proprietary software for?

>About Debian Edu and Skolelinux
</p
>
1122 <p
>Debian Edu, also known as Skolelinux, is a Linux distribution based
1123 on Debian providing an out-of-the box environment of a completely
1124 configured school network. Immediately after installation a school
1125 server running all services needed for a school network is set up just
1126 waiting for users and machines being added via GOsa², a comfortable
1127 Web-UI. A netbooting environment is prepared using PXE, so after
1128 initial installation of the main server from CD or USB stick all other
1129 machines can be installed via the network. The provided school server
1130 provides LDAP database and Kerberos authentication service,
1131 centralized home directories, DHCP server, web proxy and many other
1132 services. The desktop contains more than
60 educational software
1133 packages and more are available from the Debian archive, and schools
1134 can choose between KDE, Gnome, LXDE and Xfce desktop environment.
</p
>
1136 <p
>This is the seventh test release based on Debian Wheezy. Basically
1137 this is an updated and slightly improved version compared to the
1138 Squeeze release.
</p
>
1140 <p
>Notes for upgrades from Alpha Prereleases
</p
>
1142 <p
>Alpha based installations should reinstall or downgrade the
1143 versions of gosa and libpam-mklocaluser to the ones used in this beta
1144 release. Both alpha and beta0 based installations should reinstall or
1145 deal with gosa.conf manually; there are two options: (
1) Keep
1146 gosa.conf and edit this file as outlined on the mailing list. (
2)
1147 Accept the new version of gosa.conf and replace both contained admin
1148 password placeholders with the password hashes found in the old one
1149 (backup copy!). In both cases all users need to change their password
1150 to make sure a password is set for CIFS access to their home
1151 directory.

">Debian Edu, also known as
1310 Skolelinux
</a
>, is a Linux distribution based on Debian providing an
1311 out-of-the box environment of a completely configured school
1312 network. Immediately after installation a school server running all
1313 services needed for a school network is set up just waiting for users
1314 and machines being added via GOsa², a comfortable Web-UI. A netbooting
1315 environment is prepared using PXE, so after initial installation of
1316 the main server from CD, DVD or USB stick all other machines can be
1317 installed via the network. The provided school server provides LDAP
1318 database and Kerberos authentication service, centralized home
1319 directories, DHCP server, web proxy and many other services. The
1321 <a href=
"http://people.skolelinux.org/pere/blog/Educational_applications_included_in_Debian_Edu___Skolelinux__the_screenshot_collection____.html
">more
1322 than
60 educational software packages
</a
> and more are available from
1323 the Debian archive, and schools can choose between KDE, Gnome, LXDE
1324 and Xfce desktop environment.
</p
>
1326 <p
>This is the fifth test release based on Debian Wheezy. Basically
1327 this is an updated and slightly improved version compared to the
1328 Squeeze release.
</p
>
1330 <p
>ALERT: Alpha based installations should reinstall or downgrade the
1331 versions of gosa and libpam-mklocaluser to the ones used in this beta
1334 <p
><strong
>Software updates
</strong
></p
>
1338 <li
>Switched roaming workstation profiles from wicd to network-manager
1339 for network configuration, as wicd didn
't work any more.
</li
>
1340 <li
>Changed version numbers of patched gosa and libpam-mklocaluser
1341 packages to make sure our locally patched versions will be replaced
1342 by the official packages when they are released from Debian. Those
1343 installing alpha version need to reinstall or manually downgrade gosa
1344 and libpam-mklocaluser.
</li
>
1345 <li
>Added bluetooth tools to the default desktop (bluedevil, blueman).
</li
>
1346 <li
>Added tools for sharing the desktop on KDE (krdc, krfb).
</li
>
1347 <li
>Added valgrind to the default installation for easier debugging of
1348 crash bugs.
</li
>
1352 <p
><strong
>Other changes
</strong
></p
>
1356 <li
>Fixed artwork package to work with gnome, no longer break
1357 desktop=gnome installations.
</li
>
1358 <li
>Adjusted installer to now work when forced to use a proxy with the
1359 netinst CD.
</li
>
1360 <li
>Fixed code detecting and setting/loading hardware specific
1361 setup/firmware to work more robust out of the box.
</li
>
1362 <li
>Adjusted Kerberos setup to detect realm and server settings at
1363 install time instead of dynamically at run time. This avoid a crash
1364 with krb5-auth-dialog on diskless workstations without a DNS name.
</li
>
1365 <li
>Worked around misfeature in network-manager not calling the dhclient
1366 exit hooks, causing automatic proxy configuration and automatic host
1367 name setting at run time to work again.
</li
>
1368 <li
>Fixed feature setting the default Iceweasel start page from URL
1369 fetched from LDAP, to allow schools to set the global default by
1370 updating the dc=skole,dc=skolelinux,dc=no LDAP object.
</li
>
1371 <li
>Changed default host name on all networked machines to be unique
1372 (generated from MAC or reverse DNS) after boot.
</li
>
1373 <li
>Adjusted partition sizes to make sure they are big enough.
</li
>
1377 <p
><strong
>Known issues
</strong
></p
>
1381 <li
>Grub is missing the new artwork.
</li
>
1382 <li
>KDE fail to understand the wpad.dat file provided, causing it to
1383 not use the http proxy as it should.
</li
>
1384 <li
>Chromium also fail to use the proxy.

1485 <li
>Dropped ispell dictionaries from our default installation.
</li
>
1486 <li
>Dropped menu-xdg from the KDE desktop option, to drop the Debian
1487 submenu. It was not included with Gnome, LXDE or Xfce, so this
1488 brings KDE in line with the others.
</li
>
1489 <li
>Dropped xdrawchem, xjig and xsok from our default installation as
1490 they don
't have a desktop menu entry and thus won
't show up in the
1491 menu now that menu-xdg was removed.
</li
>
1492 <li
>Removed the killer system to kill left behind processes on
1493 multi-user machines, as it was no longer able to understand when a
1494 X display was in use and killed the processes of the active users
1496 <li
>Dropped the golearn (from goplay) package as the debtags in wheezy
1497 are too few to make the package useful.

1508 d-i is doing it.

>
1509 <li
>Made sure root and user passwords were not left behind in the
1510 debconf database after installation on Main Server installations.
</li
>
1511 <li
>Made Roaming Workstation dynamic setup more robust and added draft
1512 script setup-ad-client to hook a Roaming Workstation up to a
1513 Active Directory server instead of a Debian Edu Main Server.
</li
>
1514 <li

1516 <li

1518 and keymap settings to PXE installation clients.

>In the
<a href=
"http://www.skolelinux.org/
">Debian Edu /
1562 Skolelinux
</a
> project, we include a post-installation test suite,
1563 which check that services are running, working, and return the
1564 expected results. It runs automatically just after the first boot on
1565 test installations (using test ISOs), but not on production
1566 installations (using non-test ISOs). It test that the LDAP service is
1567 operating, Kerberos is responding, DNS is replying, file systems are
1568 online resizable, etc, etc. And it check that the PXE service is
1569 configured, which is the topic of this post.
</p
>
1571 <p
>The last week I
've fixed the DVD and USB stick ISOs for our Debian
1572 Edu Wheezy release. These ISOs are supposed to be able to install a
1573 complete system without any Internet connection, but for that to
1574 happen all the needed packages need to be on them. Thanks to our test
1575 suite, I discovered that we had forgotten to adjust our PXE setup to
1576 cope with the new names and paths used by the netboot d-i packages.
1577 When Internet connectivity was available, the installer fall back to
1578 using wget to fetch d-i boot images, but when offline it require
1579 working packages to get it working. And the packages changed name
1580 from debian-installer-
6.0-netboot-$arch to
1581 debian-installer-
7.0-netboot-$arch, we no longer pulled in the
1582 packages during installation. Without our test suite, I suspect we
1583 would never have discovered this before release. Now it is fixed
1584 right after we got the ISOs operational.
</p
>
1586 <p
>Another by-product of the test suite is that we can ask system
1587 administrators with problems getting Debian Edu to work, to run the
1588 test suite using
<tt
>/usr/sbin/debian-edu-test-install
</tt
> and see if
1589 any errors are detected. This usually pinpoint the subsystem causing
1590 the problem.

1622 community and even gathered a nice Debian-ish crowd. Since then, I
1623 began my quest as a free software hacker and activist and I am
1624 constantly trying to cover as much ground as possible on that
1627 <p
>A few years ago I founded a small web development company, which
1628 provided me the flexible schedule I needed so much for my
1629 activities. For the last
13 months, I have been the Technical Director
1630 of
<a href=
"http://ceata.org/
">Fundația Ceata
</a
>, which is a free
1631 software activist organisation endorsed by the FSF and the FSFE, and
1632 the only one we have in our country.
</p
>
1634 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
1635 project?
</strong
></p
>
1637 <p
>The idea of participating in the Debian Edu project was a surprise
1638 even to me, since I never used it before I began getting involved in
1639 it. This year I had a great opportunity to deliver a talk on
1640 educational software, and I knew immediately where to look. It was a
1641 love at first sight, since I was previously involved with some of the
1642 technologies the project incorporates, and I rapidly found a lot of
1643 ways to contribute.
</p
>
1645 <p
>My first contributions consisted in translating the installer and
1646 configuration dialogs, then I found some bugs to squash (I still
1647 haven
't fixed them yet though), and I even got my eyes on some other
1648 areas where I can prove myself helpful. Since the appetite for free
1649 software in my country is pretty low, I
'll be happy to be the first
1650 one around here advocating for the project
's adoption in educational
1651 environments, and maybe even get my hands dirty in creating a flavour
1652 for our own needs. I am not used to make very advanced plannings, so
1653 from now on, time will tell what I
'll be doing next, but I think I
1654 have a pretty consistent starting point.
</p
>
1656 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
1657 Edu?
</strong
></p
>
1659 <p
>Not a long time ago, I was in the position of configuring and
1660 maintaining a LDAP server on some Debian derivative, and I must say it
1661 took me a while. A long time ago, I was maintaining a bigger
1662 Samba-powered infrastructure, and I must say I spent quite a lot of
1663 time on it. I have similar stories about many of the services included
1664 with Skolelinux, and the main advantage I see about it is the
1665 out-of-the box availability of them, making it quite competitive when
1666 it comes to managing a school
's network, for example.
</p
>
1668 <p
>Of course, there is more to say about Skolelinux than the
1669 availability of the software included, its flexibility in various
1670 scenarios is something I can
't wait to experiment
"into the wild
" (I
1671 only played with virtual machines so far). And I am sure there is a
1672 lot more I haven
't discovered yet about it, being so new within the
1675 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
1676 Edu?
</strong
></p
>
1678 <p
>As usual, when it comes to Debian Blends, I see as the biggest
1679 disadvantage the lack of a numerous team dedicated to the
1680 project. Every day I see the same names in the changelogs, and I have
1681 a constantly fear of the bus factor in this story. I
'd like to see
1682 Debian Edu advertised more as an entry point into the Debian
1683 ecosystem, especially amongst newcomers and students. IMHO there are a
1684 lot low-hanging fruits in terms of bug squashing, and enough
1685 opportunities to get the feeling of the Debian Project
's dynamics. Not
1686 to mention it
's a very fun blend to work on!
</p
>
1688 <p
>Derived from the previous statement, is the delay in catching up
1689 with the main Debian release and documentation. This is common though
1690 to all blends and derivatives, but it
's an issue we can all work
1693 <p
><strong
>Which free software do you use daily?
</strong
></p
>
1695 <p
>I can hardly imagine myself spending a day without Vim, since my
1696 daily routine covers writing code and hacking configuration files. I
1697 am a fan of the Awesome window manager (but I also like the
1698 Enlightenment project a lot!),
1699 <a href=
"http://www.claws-mail.org/
">Claws Mail

1700 use and very configurable behaviour. Recently I fell in love with
1701 <a href=
"https://launchpad.net/redshift

1702 get through the night without headaches. Of course, there is much more
1703 stuff in this bag, but I
'll need a blog on my own for doing this!

1705 <p
><strong
>Which strategy do you believe is the right one to use to
1706 get schools to use free software?
</strong

1708 <p
>Well, on this field, I cannot do much more than experiment right
1709 now. So, being far from having a recipe for success, I can only assume
1714 <li
>schools would like to get rid of proprietary software
</li
>
1716 <li
>students will love the openness of the system, and will want to
1717 experiment with it - maybe we need to harvest the native curiosity
1718 of teenagers more?
</li
>
1720 <li
>there is no
"right one
" when it comes to strategies, but it would
1721 be useful to have some success stories published somewhere, so
1722 other can get some inspiration from them (I know I
'd promote
1725 <li
>more active promotion - talks, conferences, even small school
1726 lectures can do magical things if they encounter at least one
1727 person interested. Who knows who that person might be? ;-)
</li
>
1731 <p
>I also see some problems in getting Skolelinux into schools; for
1732 example, in our country we have a great deal of corruption issues, so
1733 it might be hard(er) to fight against proprietary solutions. Also,
1734 people who relied on commercial software for all their lives, would be
1735 very hard to convert against their will.

>There is a certain cross-over between the
1745 <a href=

">Debian Edu / Skolelinux
1746 project
</a
> and
<a href=
"http://www.edubuntu.org/

</a

1748 effort between the projects. One person with a foot in both camps is
1749 Jonathan Carter, which I am now happy to present to you.
</p
>
1751 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
1753 <p
>I
'm a South-African free software geek who lives in Cape Town. My
1754 days vary quite a bit since I
'm involved in too many things. As I
'm
1755 getting older I
'm learning how to focus a bit more :)
</p
>
1757 <p
>I
'm also an Edubuntu contributor and I love when there are
1758 opportunities for the Edubuntu and Debian Edu projects to benefit from
1759 each other.
</p
>
1761 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
1762 project?
</strong
></p
>
1764 <p
>I
've been somewhat familiar with the project before, but I think my
1765 first direct exposure to the project was when I met Petter
1766 [Reinholdtsen] and Knut [Yrvin] at the Edubuntu summit in
2005 in
1767 London. They provided great feedback that helped the bootstrapping of
1768 Edubuntu. Back then Edubuntu (and even Ubuntu) was still very new and
1769 it was great getting input from people who have been around longer. I
1770 was also still very excitable and said yes to everything and to this
1771 day I have a big todo list backlog that I
'm catching up with. I think
1772 over the years the relationship between Edubuntu and Debian-Edu has
1773 been gradually improving, although I think there
's a lot that we could
1774 still improve on in terms of working together on packages. I
'm sure
1775 we
'll get there one day.
</p
>
1777 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
1778 Edu?
</strong
></p
>
1780 <p
>Debian itself already has so many advantages. I could go on about
1781 it for pages, but in essence I love that it
's a very honest project
1782 that puts its users first with no hidden agendas and also produces
1783 very high quality work.
</p
>
1785 <p
>I think the advantage of Debian Edu is that it makes many common
1786 set-up tasks simpler so that administrators can get up and running
1787 with a lot less effort and frustration. At the same time I think it
1788 helps to standardise installations in schools so that it
's easier for
1789 community members and commercial suppliers to support.
</p
>
1791 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
1792 Edu?
</strong
></p
>
1794 <p
>I had to re-type this one a few times because I
'm trying to
1795 separate
"disadvantages
" from
"areas that need improvement
" (which is
1796 what I originally rambled on about)
</p
>
1798 <p
>The biggest disadvantage I can think of is lack of manpower. The
1799 project could do so much more if there were more good contributors. I
1800 think some of the problems are external too. Free software and free
1801 content in education is a no-brainer but it takes some time to catch
1802 on. When you
've been working with the same proprietary eco-system for
1803 years and have gotten used to it, it can be hard to adjust to some
1804 concepts in the free software world. It would be nice if there were
1805 more Debian Edu consultants across the world. I
'd love to be one
1806 myself but I
'm already so over-committed that it
's just not possible
1807 currently.
</p
>
1809 <p
>I think the best short-term solution to that large-scale problem is
1810 for schools to be pro-active and share their experiences and grow
1811 their skills in-house. I
'm often saddened to see how much money
1812 educational institutions spend on
3rd party solutions that they don
't
1813 have access to after the service has ended and they could
've gotten so
1814 much more value otherwise by being more self-sustainable and
1815 autonomous.
</p
>
1817 <p
><strong
>Which free software do you use daily?
</strong
></p
>
1819 <p
>My main laptop dual-boots between Debian and Windows
7. I was
1820 Windows free for years but started dual-booting again last year for
1821 some games which help me focus and relax (Starcraft II in
1822 particular). Gaming support on Linux is improving in leaps and bounds
1823 so I suppose I
'll soon be able to regain that disk space :)
</p
>
1825 <p
>Besides that I rely on Icedove, Chromium, Terminator, Byobu, irssi,
1826 git, Tomboy, KVM, VLC and LibreOffice. Recently I
've been torn on
1827 which desktop environment I like and I
'm taking some refuge in Xfce
1828 while I figure that out. I like tools that keep things simple. I enjoy
1829 Python and shell scripting. I went to an Arduino workshop recently and
1830 it was awesome seeing how easy and simple the IDE software was to get
1831 up and running in Debian compared to the users running Windows and OS
1834 <p
>I also use mc which some people frown upon slightly. I got used to
1835 using Norton Commander in the early
90's and it stuck (I think the
1836 people who sneer at it is just jealous that they don
't know how to use
1839 <p
><strong
>Which strategy do you believe is the right one to use to
1840 get schools to use free software?
</strong
></p
>
1842 <p
>I think trying to force it is unproductive. I also think that in
1843 many cases it
's appropriate for schools to use non-free systems and I
1844 don
't think that there
's any particular moral or ethical problem with
1847 <p
>I do think though that free software can already solve so so many
1848 problems in educational institutions and it
's just a shame not taking
1849 advantage of that.
</p
>
1851 <p
>I also think that some curricula need serious review. For example,
1852 some areas of the world rely heavily on very specific versions of MS
1853 Office, teaching students to parrot menu items instead of learning the
1854 general concepts. I think that
's very unproductive because firstly, MS
1855 Office
's interface changes drastically every few years and on top of
1856 that it also locks in a generation to a product that might not be the
1857 best solution for them.
</p
>
1859 <p
>To answer your question, I believe that the right strategy is to
1860 educate and inform, giving someone the information they require to
1861 make a decision that would work for them.

">Debian Edu, also known as
1882 Skolelinux
</a
>, is a Linux distribution based on Debian providing an
1883 out-of-the box environment of a completely configured school
1884 network. Immediately after installation a school server running all
1885 services needed for a school network is set up just waiting for users
1886 and machines being added via GOsa², a comfortable Web-UI. A netbooting
1887 environment is prepared using PXE, so after initial installation of
1888 the main server from CD, DVD or USB stick all other machines can be
1889 installed via the network. The provided school server provides LDAP
1890 database and Kerberos authentication service, centralized home
1891 directories, DHCP server, web proxy and many other services. The

2026 pulling along to get the Wheezy based release out the door, and this
2027 time I managed to get an interview from one of the French translators
2028 in the project, Cédric Boutillier.

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

2032 <p
>I am
34 year old. I live near Paris, France. I am an assistant
2033 professor in probability theory. I spend my daytime teaching
2034 mathematics at the university and doing fundamental research in
2035 probability in connexion with combinatorics and statistical physics.
</p
>
2037 <p
>I have been involved in the Debian project for a couple of years
2038 and became Debian Developer a few months ago. I am working on Ruby
2039 packaging, publicity and translation.
</p
>
2041 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
2042 project?
</strong
></p
>
2044 <p
>I came to the Debian Edu project after a call for translation of
2045 <a href=
"http://wiki.debian.org/DebianEdu/Documentation/Manuals
">the
2046 Debian Edu manual
</a
> for the release of Debian Edu Squeeze. Since
2047 then, I have been working on updating the French translation of the
2050 <p
>I had the opportunity to make an installation of Debian Edu in a
2051 virtual machine when I was preparing localised version of some screen
2052 shots for the manual. I was amazed to see it worked out of the box and
2053 how comprehensive the list of software installed by default was.
</p
>
2055 <p
>What amazed me was the complete network infrastructure directly
2056 ready to use, which can and the nice administration interface provided
2057 by
<a href=
"https://oss.gonicus.de/labs/gosa/
">GOsa²
</a
>. What pleased
2058 me also was the fact that among the software installed by default,
2059 there were many
"traditional
" educative software to learn languages,
2060 to count, to program... but also software to develop creativity and
2061 artistic skills with music (
<a href=
"http://ardour.org/
">Ardour
</a
>,
2062 <a href=
"http://audacity.sourceforge.net/
">Audacity
</a
>) and
2063 movies/animation (I was especially thinking of
2064 <a href=
"http://linuxstopmotion.sourceforge.net/
">Stopmotion
</a
>).
</p
>
2066 <p
>I am following the development of Debian Edu and am hanging out on
2067 <a href=
"irc://irc.debian.org/%
23debian-edu
">#debian-edu
</a
>.
2068 Unfortunately, I don
't much time to get more involved in this
2069 beautiful project.
</p
>
2071 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
2072 Edu?
</strong
></p
>
2074 <p
>For me, the main advantages of Skolelinux/Debian Edu are its
2075 community of experts and its precise documentation, as well as the
2076 fact that it provides a solution ready to use.
</p
>
2078 <p
>I would add also the fact that it is based on the rock solid Debian
2079 distribution, which ensures stability and provides a huge collection
2080 of educational free software.
</p
>
2082 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
2083 Edu?
</strong
></p
>
2085 <p
>Maybe the lack of manpower to do lobbying on the
2086 project. Sometimes, people who need to take decisions concerning IT do
2087 not have all the elements to evaluate properly free software
2088 solutions. The fact that support by a company may be difficult to find
2089 is probably a problem if the school does not have IT personnel.
</p
>
2091 <p
>One can find support from a company by looking at
2092 <a href=
"http://wiki.debian.org/DebianEdu/Help/ProfessionalHelp
">the
2093 wiki dokumentation
</a
>, where some countries already have a number of
2094 companies providing support for Debian Edu, like Germany or
2095 Norway. This list is easy to find readily from the manual. However,
2096 for other countries, like France, the list is empty. I guess that
2097 consultants proposing support for Debian would be able to provide some
2098 support for Debian Edu as well.
</p
>
2100 <p
><strong
>Which free software do you use daily?
</strong
></p
>
2102 <p
>I am using the KDE Plasma Desktop. But the pieces of software I use
2103 most runs in a terminal: Mutt and OfflineIMAP for emails, latex for
2104 scientific documents, mpd for music. VIM is my editor of choice. I am
2105 also using the mathematical software
2106 <a href=
"http://www.scilab.org/en/scilab/about
">Scilab
</a
> and
2107 <a href=
"http://www.sagemath.org/index.html
">Sage
</a
> (built from
2108 source as not completely packaged for Debian, yet).
2110 <p
><strong
>Do you have any suggestions for teachers interested in
2111 using the free software in Debian to teach mathematics and
2112 statistics?
</strong
></p
>
2114 <p
>I do not have any
"nice
" recommendations for statistics. At our
2115 university, we use both
<a href=
"http://www.r-project.org/
">R
</a
> and
2116 Scilab to teach statistics and probabilistic simulations. For
2117 geometry, there are nice programs:
</p
>
2121 <li

"http://www.drgeo.eu/
">drgeo
</a
> and
2122 <a href=
"http://edu.kde.org/applications/all/kig

</a
> to do
2123 constructions in planar geometry
2125 <li
><a href=
"http://www.geom.uiuc.edu/software/download/kali.html
">kali
</a
>
2126 to discover symmetry groups (the so-called wallpapers and frieze
2127 groups), although the interface looks a bit old.
</li

2136 <p
><strong
>Which strategy do you believe is the right one to use to
2137 get schools to use free software?
</strong
></p
>
2139 <p
>My suggestions would be to
</p
>
2143 <li
>advertise the reduction of costs when free software is used.
</li
>
2145 <li
>communicate about the quality of free software projects, using
2146 well known examples like Firefox, ThunderBird and
2147 OpenOffice.org/LibreOffice.
</li
>
2149 <li
>advertise the living and strong community around the project.
</li

2313 <p
>Jeg heter Nirosan Thiyagalingam. Jeg er
24 år og studerer
2314 dataingeniør studiet ved Høgskolen i Sør Trøndelag. Interessen for
2315 data har siden ung alder vært tilstede og jeg har i tillegg alltid
2316 vært glad i å lære nye ting. Med teknologi som endres svært hurtig er
2317 det alltid noe nytt å lære. Noe som igjen har gjort det svært
2318 interessant å følge med på utviklingen. Jeg valgte dataingeniør
2319 studiet grunnet ønske om å lære enda mer om programmering og utvikling
2320 av store systemer.
</p
>
2322 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
2324 <p
>Skolelinux prosjektet hørte jeg først om i media. Men det var først
2325 når jeg skulle velge bacheloroppgave at jeg fattet mer interesse for
2326 prosjektet. Et enkelt søk på nettet førte meg til skolelinux sine
2327 hjemmesider. Informasjonen jeg fant der gjorde meg enda nysgjerrig og
2328 jeg valgte derfor en oppgave som gikk ut på å få en
2329 <a href=
"http://www.raspberrypi.org
">Raspberry PI
</a
>. Altså en
2330 ultra-billig datamaskin til å kjøre Debian Edu på lik linje med
2331 vanlige datamaskiner. I løpet av prosjektet ble det gjort mye
2332 forskning på nettet. Det var mye jeg måtte forstå rundt hvordan
2333 operativsystemet Linux fungerte før jeg kunne angripe
2334 problemet. Prøvde først å finne ut hvordan man kunne transformere en
2335 vanlig installasjon av Skolelinux til Raspberry PI, men dette var
2336 altfor vanskelig å jeg endte opp med mer spørsmål enn svar. Det ble
2337 videre opprettet kontakt med Skolelinux utviklere på IRC der jeg fikk
2338 diskutert hvilken retning jeg burde gå for å få til en fullverdig
2339 løsning. Det ble bestemt at jeg skulle gå for å først installere
2340 <a href=
"http://www.raspbian.org/
">Raspian
</a
>. Dette er et
2341 operativsystem basert på Debian spesiallaget for Raspberry Pi sin
2342 maskinvare. Nå som Debian var installert på datamaskinen gjenstod det
2343 å installere de nødvendige Skolelinux pakkene for å få til et
2344 fullverdig system. Disse pakkene ble installert manuelt i første
2345 omgang, men ble senere installert automatisk via et script som Petter
2346 Reinholdtsen laget. Dette scriptet er så enkel å bruke at man er i
2347 gang med installasjonen i løpet av bare
5 minutter. Ikke nok med det,
2348 alt skjer helt automatisk. Alt i alt er jeg veldig fornøyd med
2349 resultatet av installasjonsprosessen. Raspberry Pi er en veldig svak
2350 maskin og det merkes godt når man har installert Skolelinux på
2351 den. Video og
3D-rendering fungerer utrolig dårlig, men nettsurfing og
2352 kontorprogrammer fungerer godt. Det kan derfor konkluderes med at
2353 datamaskinen er egnet for enkle oppgaver.
2355 <p
>Jeg syns det er viktig påpeke at dette kun er startfasen av en slik
2356 løsning. På markedet finnes det nå maskiner som har bedre hardware enn
2357 Raspberry Pi. Det er store muligheter for at man kan klare å
2358 installere Skolelinux på disse også, og da forsvinner nok mest
2359 sannsynlig ytelsesproblemene med Video og
3D rendering også.
</p
>
2361 <p
>Det ble også prøvd med en løsning som gjorde at Raspberry Pi
2362 fungerte som en tynnklient. Denne løsningen hadde langt bedre ytelse
2363 med tanke på hastighet og brukeropplevelse. Men også her var video og
2364 3D rendering dårlig. Det ble brukt en liten Linux distribusjon kalt
2365 <a href=

</a

2368 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
2370 <p
>Fordelen med Skolelinux er mange. At det er gratis er en stor
2371 fordel, men at det er så mange som er med på å utvikle det og
2372 vedlikeholde det er en enda større fordel. Allerede før jeg startet
2373 med prosjektet så jeg mange fordeler, og når jeg nærmet meg sluttfasen
2374 så jeg langt flere. At prosjektet skulle inneha en så høy kvalitet
2375 hadde jeg aldri trodd. En vanlig Skolelinux installasjon har de
2376 nødvendige programmene og funksjonen som både små og store skoler i
2377 tillegg til organisasjoner kan klare seg med. At prosjektet tilbyr en
2378 så komplett løsning er en kjempefordel. Installasjonen er knirkefri
2379 og det er svært enkelt å installere og komme i gang.
</p
>
2381 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
2383 <p
>Ulempene jeg ser med prosjektet er ryddigheten av websidene. Selv
2384 om websidene er enkle og konsise er det allikevel ikke appellerende i
2385 like stor grad som for eksempel
2386 <a href=
"http://www.ubuntu.com
">Ubuntu
</a
> sine sider. Deres side
2387 tilbyr, i tillegg til godt design og presentasjon, en nettbasert
2388 emulator av deres operativsystem. Dette er en stor fordel slik jeg ser
2389 det. Bortsett fra dette ser jeg absolutt ingen ulemper med
2390 Skolelinux-prosjektet.
</p
>
2392 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
2394 <p
>Til daglig er jeg en flittig bruker av det åpne media
2395 sentersystemet
<a href=
"http://xbmc.org/
">XBMC
</a
>. Det enorme
2396 samfunnet rundt dette prosjektet har gjort dette til et program som
2397 dekker alles behov. Man kan tilpasse det akkurat slik man vil både med
2398 tanke på utseende og funksjoner ved installere plug-ins eller
2401 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
2402 skoler til å ta i bruk fri programvare?
</strong
></p
>
2404 <p
>Strategien som burde brukes sett fra mine øyne er
2405 markedsføring. Jeg er sikker på at om flere skoler fikk et lite innsyn
2406 i hvor bra Skolelinux er så ville de ikke nølt med å gå over fra noe
2407 annet som koster de store summer. At skolelinux til de grader tilbyr
2408 en så komplett løsning bure komme frem. Enten via reklamekampanjer
2409 eller ved å sende ut folk til skoler for så å la skolenettverk
2410 ansvarlige få teste ut hvordan Skolelinux fungerer i praksis. Om det
2411 i tillegg ble utviklet gode websider og en emulator for å la brukere
2412 prøve operativsystemet ville nok dette ha styrket inntrykket
2413 betraktelig.

2423 an operating system based on Debian intended for use in schools. It
2424 contain a turn-key solution for the computer network provided to
2425 pupils in the primary schools. It provide both the central server,
2426 network boot servers and desktop environments with heaps of
2427 educational software. The project was founded almost
12 years ago,

>A topic that come up again and again on the Debian Edu mailing
2434 lists and elsewhere, is the question on how to transform a Debian or
2435 Ubuntu installation into a Debian Edu installation. It isn
't very
2436 hard, and last week I wrote a script to replicate the steps done by
2437 the Debian Edu installer.
</p

2439 <p
>The script,
2440 <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/
>
2441 in the debian-edu-config package, will go through these six steps and
2442 transform an existing Debian Wheezy or Ubuntu (untested) installation
2443 into a Debian Edu Workstation:
</p
>
2447 <li
>Add skolelinux related APT sources.
</li
>
2448 <li
>Create /etc/debian-edu/config with the wanted configuration.
</li
>
2449 <li
>Install debian-edu-install to load preseeding values and pull in
2450 our configuration.
</li
>
2451 <li
>Preseed debconf database with profile setup in
2452 /etc/debian-edu/config, and run tasksel to install packages
2453 according to the profile specified in the config above,
2454 overriding some of the Debian automation machinery.
</li
>
2455 <li
>Run debian-edu-cfengine-D installation to configure everything
2456 that could not be done using preseeding.
</li
>
2457 <li
>Ask for a reboot to enable all the configuration changes.
</li
>
2461 <p
>There are some steps in the Debian Edu installation that can not be
2462 replicated like this. Disk partitioning and LVM setup, for example.
2463 So this script just assume there is enough disk space to install all
2464 the needed packages.

2507 <p
>Debian Edu, also known as Skolelinux, is a Linux distribution based
2508 on Debian providing an out-of-the box environment of a completely
2509 configured school network. Immediatly after installation a school
2510 server running all services needed for a school network is set up just
2511 waiting for users and machines being added via GOsa², a comfortable
2512 Web-UI. A netbooting environment is prepared using PXE, so after
2513 initial installation of the main server from CD, DVD or USB stick all
2514 other machines can be installed via the network.
</p

2601 i Narvikskolene og konstnaden ved å gå over til Windows. For litt

9 millioner
2611 for å gå over til Windows på skolene. I tillegg dokumenterer notatet
2612 at læreplanens krav oppfylles uten problemer ved bruk av Skolelinux.
2613 Jeg anbefaler alle å lese de
10 sidene med gode argumenter for å kutte
2614 unødige utgifter på IT i skoleverket. :)

6. He installed the standalone profile and
2800 the video show a walk-through of of the menu content, demonstration of
2801 a few programs and his view of our distribution.
</p
>
2803 <p
>There is also some really nice quotes (transcribed by me, might
2804 have heard wrong). While looking thought the Graphics menu:
</p
>
2807 "Basically everything you ever need in a school environment.
"
2810 <p
>And as a general evaluation of the entire distribution:
</p
>
2813 "So, yeah, a bit bloated. It kept all the Debian stuff in there, just
2814 to keep it nice and GNU. So, I do not want to go on about it, but
2815 lets give it
7 out of
10. I am not going to use it. That is because
2816 I am not deploying a school network. There may be some mythical
2817 feature to help you deploy Skolelinux on a school network.
"
2820 <p
>To bad he did not test the server profile, and discovered the PXE
2821 installation option. It make it possible to install only the main
2822 server from CD, and the rest of the machines via the net, and might be
2823 considered the mythical feature he talk about. :)
</p
>
2825 <p
>While looking through the menus, there is also this funny comment
2826 about the part of the K menu generated from the Debian menu subsystem:
2829 "[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
2951 samlet et nytt intervju med en av folkene i
2952 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet.
2953 Denne gang er det Helge Tore Høyland, en mangeårig bidragsyter på
2954 epostlistene og ellers i prosjektet.
</p
>
2956 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
2958 <p
>Eg er IT-konsulent/teknikker hjå eit firma i Steinkjer med navn
2959 <a href=
"http://unoit.no/
">Uno IT
</a
>. Uno IT er eit lite firma som
2960 drifter nettverk og maskiner for små og mellomstore firma
2961 Steinkjer-området. Per dags dato er me
2 ansatte. Min faglege bakgrunn
2962 er Fagbrev som it-teknikker, samt nokre fag innen nettverk- og
2963 server-drift frå HiST og NTNU. Dagleg arbeid består i oppsett av nye
2964 maskiner og hjelp til sluttbrukere, samt oppsett og vedlikehold av eit
2965 vidt spekter av fagsystemer ute hjå kunder. Erfaring med Skolelinux
2966 har eg hatt i forbindelse med drifting av
2967 <a href=
"http://www.bjorkly.no/
">Bjørkly skule
</a
>, ein privat
2968 grunnskule i Namsos-området. I dag har skulen
65 elever,
15 lærere,
1
2969 hovedserver og ca
60 klienter som kjører halvtjukt. Eg har bygd og
2970 driftet systemet sidan summaren
2006.
</p
>
2972 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
2974 <p
>Eg kom i kontakt med Skolelinux-prosjektet via ein artikkel i eit
2975 fagblad, som eg ikkje lenger hugsar namnet på. I og med at eg allereie
2976 hadde pusla med nettverk for ein annan skule, fatta eg straks
2977 interesse for prosjektet.
</p
>
2979 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
2981 <p
>Fordelane med Skolelinux er sentralisert administrasjon og svært
2982 mange gode verktøy «ut av boksen». Veldig kjekt å kunne drifte
60
2983 klientar med berre å «bry» seg med ein server. Levetid for systemets
2984 hardware er og ein veldig fin effekt. I tillegg kjem fordelar som økt
2985 sikkerhet og mindre lisenskostnader. Etter min erfaring er det og
2986 mykje mindre driftskostnader med eit slikt system enn konkurrerande
2987 system, pga enkelhet med sentralisert administrasjon. På grunn av at
2988 Skolelinux er basert på Debian er det òg svært stabilt.
</p
>
2990 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
2992 <p
>Ulemper er mangel på vilje til å følge standarer ute i markedet,
2993 som fører til mangel på støtte til nokre mykje brukte ting. Flash og
2994 Java er typiske eksempel. Sidan Debian satsar på stabilitet framfor å
2995 ha nyeste pakke av eit program, kan ein i nokre tilfeller kome borti
2996 at program vert «for gamle». Det er spesielt nettlesaren som er
2997 utsett. Mangel på vilje til å utvikle pedagogisk programvare, i Noreg,
2998 for «alle» platformer fører òg til noko hovudbry.
</p
>
3000 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
3002 <p
>Til dagleg bruker eg svært mange forskjellige «fri programvare»
3003 program. Firefox, Thunderbird, Freecommander, ImgBurn, Clonezilla,
3004 OCS inventory, Icinga, Skolelinux, SystemRescueCD og mykje meir.
</p
>
3006 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
3007 skoler til å ta i bruk fri programvare?
</strong
></p
>
3009 <p
>Strategisk må ein fokusere på at sluttbruker eigentleg ikkje er så
3010 fokusert på at det er fri programvare men at det skal «berre fungere».
3011 Gjer det enkelt å bruker og ikkje minst å administrere. For Skolelinux
3012 sin del må ein få eit betre fokus på overganger. Utbytting av servere
3013 må gå meir automatisk, import og eksport av brukerbase og maskinbase
3014 med meir må kunne gå enkelt og oppgradering til neste versjon må bli
3015 mykje meir automatisk og gjennomtesta. Ein må unngå at ein må sette
3016 opp frå start når ein byter ut ein server eller oppgraderer til neste
3017 versjon. For å få Skolelinux til å bli eit betre alternativ for skular
3018 må ein ha fokus på nettlesaren. Denne må bli «up to date» og støtte
3019 dei protokollar og tillegg som vert brukt av forlag med meir. Etter
3020 kvart som meir og meir blir flytta ut i «skya» vert dette viktigare og
3021 viktigare. Ein kunne ynskje og jobbe for at forlag med fleire tar i
3022 bruk opne standarer, men inntil det skjer, må systemet kunne brukast
3023 mot desse fagsystema.
</p
>
3025 <p
>For meg har prosjektet med Skolelinux vore ein svært artig og
3026 lærerik prosess. Miljøet rundt er ikkje enormt stort, dog stort nok,
3027 men det er svært hjelpevillig og engasjert.

3041 present. As the Debian Edu / Skolelinux project is very short on
3042 funding these days, and thus lack the money to do regular developer
3043 gatherings, this donation was most welcome. One developer gathering
3044 cost around NOK
15&nbsp;
000,-, so we need quite a lot more to keep the
3045 development pace we want. Thus, I hope their example this year is
3046 followed by many others. :)

3063 hledger, a text based system for double-entry accounting. I found it
3064 interesting, as I am involved with several organizations where
3065 accounting is an issue, and I have not really become too friendly with
3066 the different web based systems we use. I find it hard to find what I
3067 look for in the menus and even harder try to get sensible data out of
3068 the systems. Ledger seem different. The accounting data is kept in
3069 text files that can be stored in a version control system, and there
3071 are at least
<a href=
"https://github.com/ledger/ledger/wiki/Ports

3072 different implementations

3131 <p
>I am a
39-year-old woman living in the very north of Germany near
3132 Denmark. I live in a patchwork family with
"my man
" Mike Gabriel, my
3133 two daughters, Mikes daughter and Mikes and my rather newborn son.
3135 <p
>At the moment - because of our little baby - I am spending most of
3136 the day by being a caring and organising mom for all the kids.
3137 Besides that I am really involved into and occupied with several inner
3138 growth processes: New born souls always bring the whole familiar
3139 system into movement and that needs time and focus ;-). We are also
3140 in the middle of buying a house and moving to it.
</p
>
3142 <p
>In
2013 I will work again in my job in a German foundation for
3143 nature conservation. I am doing public relation work there. Besides
3144 that - and that is the connection to Skolelinux / Debian Edu - I am
3145 working in our own school project
"IT-Zukunft Schule
" in North
3146 Germany. I am responsible for the quality assurance, the customer
3147 relationship management and the communication processes in the

2001 I constantly have been training myself in communication
3151 and leadership. Besides that I am a forester, a landscaping gardener

3155 project?
</strong

>
3157 <p
>I fell in love with Mike ;-).
</p
>
3159 <p
>Very soon after getting to know him I was completely enrolled into
3160 Free Software. At this time Mike did IT-services for one newly
3161 founded school in Kiel. Other schools in Kiel needed concepts for
3162 their IT environment. Often when Mike came home from working at the
3163 newly founded school I found myself listening to his complaints about
3164 several points where the communication with the schools head or the
3165 teachers did not work. So we were clear that he would not work for
3166 one more school if we did not set up a structure for communication
3167 between him, the schools head, the teachers, the students and the
3170 <p
>Together with our friend and hardware supplier Andreas Buchholz we
3171 started to get an overview of free software solutions suitable for
3172 schools. One day before Christmas
2010 Mike and I had a date with Kurt
3173 Gramlich in Gütersloh. As Kurt and I are really interested in building
3174 networks of people and in being in communication we dived into
3175 Skolelinux and brought it to the first grammar schools in Northern

3186 answer comes rather from a social point of view.

3188 <p
>The biggest advantage of Skolelinux / Debian Edu I see is the large
3189 and strong international community of Debian Developers in the
3190 background which is very alive and connected over mailinglists, blogs
3191 and meetings. My constant feeling for the Debian Community is: If
3192 something does not work they will somehow fix it. All is well
3193 ;-). This is of course a user experience. What I also get as a big
3194 advantage of Skolelinux / Debian Edu is that everybody who uses it and
3195 works with it can also contribute to it - that includes students,
3196 teachers, parents...

3204 <p

3205 the group of developers for Debian Edu and the people who make the
3206 marketing, that means the people that bring Skolelinux to the
3207 schools. There is a lack of communication between these two groups and
3208 I think that does not really work for Skolelinux / Debian Edu.

3210 <p
>Further I appreciate that Skolelinux / Debian Edu is known as a
3211 do-ocracy. Nevertheless I keep asking myself if at some points a
3212 democracy or some kind of hierarchical project structure would be good
3213 and helpful. I am also missing some kind of contact between the
3214 Skolelinux / Debian Edu communities in Europe or on an international
3215 level. I think it would be good if there was more sharing between the
3216 different countries using Skolelinux / Debian Edu.

3228 <p

"IT-Zukunft
3229 Schule
" we have developed (and keep developing) a great way to get
3230 schools to use Free Software. We have written a detailed concept for
3231 that so I cannot explain the whole thing here. But in a nutshell the
3232 strategy has three crucial pillars:
</p
>
3236 <li
>We really take time to get what sort of stories, questions and
3237 concerns the schools head and the teachers have about using different
3238 kinds of IT and we take time to enrol them into Free Software.
</li
>
3240 <li
>Our solution for schools is never just technical. In the centre
3241 are always the people who are going to use the software. From the very
3242 beginning of the planning for a school, we tell the schools head that
3243 they are paying us not only for a technical solution for their school,
3244 they also pay us for leading all the communication processes
3245 needed. If they do not want that, we are not working with them because
3246 we cannot give a guarantee for the quality of our work then.
</li
>
3248 <li
>Another focus lies in the training of teachers and students in
3249 co-administrating the IT-System at their school. They start getting in
3250 contact with the Skolelinux / Debian Edu community and they get the
3251 offer to become more and more independent from us.

3274 <p
>I sommer (
2012-
07-
23) hadde Fremover et oppslag om at Narvik
3275 kommune hadde spart mellom
10 og
20 millioner kroner de siste årene på
3276 å bruke Skolelinux på sine skoler. Harstad har også tatt i bruk
3277 Skolelinux på alle sine skoler. Som tidligere Ballangsværing gledet
3278 det meg stort å se at skoleløsningen vi har utviklet siden
2001 tas i
3279 bruk i området der jeg vokste opp, og dermed bidrar til en bedre og
3280 billigere skolehverdag.
</p
>
3282 <p
>Skolelinux er en komplett IT-løsning for elevnettverket på en
3283 skole, med både nettverkstjenester og løsning for elevmaskiner med
3284 pedagogisk programvare, som tillater en å øke levetiden på en
3285 datamaskin i skolen med mange år. En undersøkelse publisert i mars
3286 2012 viste at de
56 norske skolene som har offentliggjort at de bruker
3287 Skolelinux eller annen Linuxutgave hadde
36% større PC-tetthet enn
3288 landsgjennomsnittet, når en ser på tall rapportert til Grunnskolens
3289 Informasjonssystem. I følge Paul Reidar Løsnesløkken, IKT-konsulent i
3290 Nord-Odal, fungerer datamaskiner godt til de er
8 til
10 år gamle.
</p
>
3292 <p
>I høst (
2012-
09-
29) fortalte Fremover hvordan Ballangen kommune har
3293 opparbeidet seg
20 millioner i underskudd og nok havner på Robek-lista
3294 fra nyttår. Kanskje Ballangen også burde ta i bruk Skolelinux for å
3295 spare penger? Hvis kommunen mangler kompetanse lokalt på Linux finnes
3296 det kommersielle selskaper som tilbyr driftstjenester rundt
3297 Skolelinux, og jeg bør vel avsløre at jeg selv er involvert i et av
3298 dem, Skolelinux Drift AS. Kommunen kan dermed få hjelp hvis de ikke
3299 ønsker å bygge opp egen kompetanse.

3469 Giorgio Pioda, which showed up on the mailing list at the start of
3470 this year, asking questions and inspiring us to improve the first time
3471 administrators experience with Skolelinux. :) The interview was
3472 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
3477 in secondary (
15-
18 year old students) and tertiary (a kind of
"light
"
3478 university) schools. Five years ago I started to manage a Learning
3479 Management Service server and slowly I got more and more involved with
3480 IT.
3 years ago the graduating schools moved completely to Linux and I
3481 got the head of the IT for this. The experience collected in chemistry
3482 labs computers (for example NMR analysis of protein folding) and in
3483 the IT-courses during university where sufficient to start. Self
3484 training is anyway very important
</p

3486 <p
>I live in the Italian speaking part of Switzerland, and the
3487 <a href=
"http://www.spse.ch/
">SPSE school
</a
> (secondary) is a very
3488 special sport school for young people who try to became sport pro (for
3489 all sports, we have dozens of disciplines represented) and we are
3490 recognised by the Olympic Swiss Organisation.

3493 project?
</strong
></p
>
3495 <p
>Looking for Linux / Primary Domain Controller (PDC) I found it
3496 already several years ago. But since the system was still not
3497 Kerberized and since our schools relies strongly on laptops I didn
't
3498 use it. I plan to introduce it in the next future, probably for the
3499 next school year, since the squeeze release solved this security
3502 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
3503 Edu?
</strong
></p
>
3505 <p
>Many. First of all there is a strong and living community that is
3506 very generous for help and hints. Chat help is crucial, together with
3507 the mailing list. Second. With Skolelinux you get an already well
3508 engineered platform and you don
't have to start to build up your PDC
3509 and your clients from GNU/scratch; I
've already done this once and I
3510 can tell it, it is hard. Third, since Skolelinux is a standard
3511 platform, it is way easier to educate other IT people and even if the
3512 head IT is sick another one could pick up the task without too much
3515 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
3516 Edu?
</strong
></p
>
3518 <p
>The only real problem I see is that it is a little too less
3519 flexible at client level. Debian stable is rocky and desirable, but
3520 there are many reasons that force for another choice. For example the
3521 need of new drivers for new PC, or the need for a specific OS for some
3522 devices that have specific software packages for another specific
3523 distribution (I have such a case for whiteboards that have only
3524 Ubuntu packages). Thus, I prepared compatibility packages educlient
3525 and eduroaming, hoping not to use them ;-)
</p

3527 <p
><strong
>Which free software do you use daily?
</strong
></p
>
3529 <p
>I have a Debian Stable PDC at school (Kerberos, NIS, NFS) with
3530 mixed Debian and Ubuntu clients. If you think that this triad
3531 combination is exotic... well I discovered right yesterday that
3532 <a href=
"http://moo.nac.uci.edu/~hjm/Perceus-Report.html
">Perceus
</a
>
3533 has the same...
</p
>
3535 <p
>For myself I run Debian wheezy/sid, but this combination is good
3536 only I you have enough competence to fix stuff for yourself, if
3537 something breaks. Daily I use texmacs, gnumeric, a little bit of R
3538 statistics, kmplot, and less frequently OpenOffice.org.
</p
>
3540 <p
><strong
>Which strategy do you believe is the right one to use to
3541 get schools to use free software?
</strong
></p
>
3543 <P
>I think that the only real argument that school managers
"hear
" is
3544 cost reduction. They don
't give too much weight on quality, stability,
3545 just because they are normally not open to change.
</p
>
3547 <p
>Students adapts very quickly to GNU/Linux (and for them being able
3548 to switch between different OS is a plus value); teachers and managers
3549 don
't.
</p
>
3551 <p
>We decided to move to Linux because students at our school have own
3552 laptop and we have the responsibility to keep the laptop ready to use;
3553 we were really unsatisfied with Microsoft since every Monday we had
20
3554 machine to fix for viral infections... With Linux this has been
3555 reduced to zero, since people installs almost only from official
3556 repositories. I think that our special needs brought us to Linux.
3557 Those who don
't have such needs will hardly move to Linux.

3576 Skolelinux er en stor suksess i Narvik siden det ble tatt i bruk i
3577 2004. Her er noen fine sitater:
</p
>
3580 "- Skolelinux har spart kommunen for store pengesummer, millionbeløp,
3581 som de heller kan bruke på andre ting, sier IKT-konsulent Viggo
3585 <p
>Avisen forteller at de har fått tilgang til beregninger som viser
3586 at Narvik kommune har spart noe mellom
10 og
20 millioner kroner de
3587 siste
8 årene på å bruke Skolelinux, og fortsetter:
</p
>
3591 "Regnestykket tar høyde for sparte kostnader til lisenser som medfølger
3592 de alternative operativsystemene, lavere driftskostnader og lengre
3593 levetid på datautstyret. Totalt har Narvikskolen en maskinpark på
3594 1600 maskiner fordelt på de
11 skolene fra Skjomen i sør til Bjerkvik
3599 <p
>Viggo Fedreheim sier dette om hvor noe av gevinsten kommer fra:
</p
>
3602 "- Vi kan gjenbruke gamle maskiner i skolen som er for dårlig andre
3603 steder i kommunen der de ikke bruker Skolelinux. Levetiden på en
3604 datamaskin blir
3-
5 år lenger med Skolelinux. Vi kaller det for
3605 grønn IT, miljøvennlig IT.
"
3608 <p
>Her er det mulighet for flere kommuner å få et godt IT-system på
3609 skolene, hvis de er villige til å forsøke. De som ikke har kompetanse
3610 innomhus kan kjøpe det fra en av de kommersielle leverandørene av

3685 <p
>I
'm a
44 year old country guy that have been working
12 years at
3686 the same school as
50% IT-manager and
50% Teacher. My educational
3687 background is fil.kand in history and religious beliefs, an exam as a
3688 "folkhighschool
" teacher, that is, for teaching grownups. In
3689 Norwegian I believe it
's called
"Vuxenupplaring
". I also have a master
3690 in
"Technology and social change
". So I
'm not really a tech guy, I
3691 just like to study how humans and technology interact and that is my
3692 perspective when working with IT.
</p
>
3694 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
3695 project?
</strong
></p
>
3697 I have followed the Skolelinux project for quite some time by
3698 now. Earlier I tested out the K12-LTSP project, which we used for some
3699 time, but I really like the idea of having a distribution aimed to be
3700 a complete solution for schools with necessary tools integrated. When
3701 K12-LTSP abandoned that idea some years ago, I started to look more
3702 seriously into Skolelinux instead.
3704 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
3705 Edu?
</strong
></p
>
3707 The big point of Skolelinux to me is that it is a complete
3708 distribution, ready to install. It has LDAP-support, MS Windows
3709 integration tools and so forth already configured, saving an
3710 administrator a lot of time and headache. We were using another Linux
3711 based thin-client system called Thinlinc, that has served us very
3712 well. But that Skolelinux is based on VNC and LTSP, to me, is better
3713 when it comes to the kind of multimedia used in schools. That is
3714 showing videos from Youtube or educational TV. It is also easier to
3715 mix thin clients with workstations, since the user settings will be the
3716 same. In our VNC-based solution you had to
"beat around the bush
" by
3717 setting up a second, hidden, home-directory for user settings for the
3718 workstations, because they will be different from the ones used on the
3719 thin clients. Skolelinux support for diskless workstations are very
3720 convenient since a school today often need to use a class room
3721 projector showing videos in full screen. That is easily done with a
3722 small integrated media computer running as a diskless workstation. You
3723 have only two installs to update and configure. One for the thin
3724 clients and one for the workstations. Also saving a lot of time. Our
3725 old system was also based on Redhat and CentOS. They are both very
3726 nice distributions, but they are sometimes painfully slow when it
3727 comes to updating multimedia support and multimedia programs (even
3728 such as Gimp), leaving us with a bit
"oldish
" applications. Debian is
3731 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
3732 Edu?
</strong
></p
>
3734 <p
>Debian is a bit too quick when it comes to updating. As an example
3735 we use old HP terminals as thinclients, and two times already this
3736 year (
2012) the updates you get from the repositories has stopped
3737 sound from working with them. It
's a kernel/ALSA issue. So you have
3738 to be more careful properly testing the updates before you run them in
3739 a production environment. This has never happened with CentOS.
</p
>
3741 <p
>I also would like to be able to set my own domain-settings at
3742 install time. In Skolelinux they are kind of hard coded into the
3743 distribution, when it comes to LDAP and at least samba integration.
3744 That is more a cosmetic/translation issue, and not a real problem.
3745 Running MS Windows applications within the Skolelinux environment needs
3746 to be better supported. That is, running them seamlessly via RDP, and
3747 support for single-sign on. That will make the transition to free
3748 software easier, because you can keep the applications you really
3749 need. No support will make it impossible if you work in a school where
3750 some applications can
't be open source. As for us we really need to
3751 run Adobe InDesign in our journalist classes. We run a journalist
3752 education, and is one of the very few non university ones that is ok:d
3753 by Svenska journalistförbundet (Swedish journalist association). Our
3754 education gives the pupils the right of membership there, once they
3755 are done. This is important if you want to get a job.
</p
>
3757 <p
>Adobe InDesign is the program most commonly used in newspapers and
3758 magazines. We used Quark Express before, but they seem to loose there
3759 market to Adobe. The only
"equivalent
" to InDesign in the opensource
3760 world is Scribus, and its not advanced enough. At least not according
3761 to the teacher. I think it would be possible to use it, because they
3762 are not supposed to learn a program, they are supposed to learn how to
3763 edit and compile a newspaper. But politically at our school we are not
3764 there yet. And Scribus lacks a lot of things you find i InDesign.
</p
>
3766 <p
>We used even a windows program for sound editing when it comes to
3767 the radio-journalist part. The year to come we are going to try
3768 Audacity. That software has the same kind of limitations compared to
3769 Adobe Audition, but that teacher is a bit more open minded. We have
3770 tried Ardour also, but that instead is more like a music studio
3771 program, not intended for the kind of editing taking place in a radio
3772 studio. Its way to complex and the GUI is to scattered when you only
3773 want to cut, make pass-overs, add extra channels and normalise. Those
3774 things you can do in Audacity, but its not as easy as in Audition. You
3775 have to do more things manually with envelopes, and that is a bit old
3776 fashion and timewasting. Its also harder to cut and move sound from
3777 one channel to another, which is a thing that you do frequently
3778 because you often find yourself needing to rearrange parts of the
3779 sound file.
</p
>
3781 <p
>So, I am not sure we will succeed in replacing even Audition, but we
3782 will try. The problem is the students have certain expectations when
3783 they start an education towards a profession. So the programs has to
3784 look and feel professional. Good thing with radio, there are many
3785 programs out there, that radio studios use, so its not as standardised
3786 as Newspaper editing. That means, it does not really matter what
3787 program they learn, because once they start working they still have to
3788 learn the program the studio uses, so instead focus has to be to learn
3789 the editing part without to much focus on a specific software.

3791 <p
><strong
>Which free software do you use daily?
</strong
></p
>
3793 <p
>Myself I
'm running Linux Mint, or Ubuntu these days. I use almost
3794 only open source software, and preferably Linux based. When it comes
3795 to most used applications its OpenOffice, and Firefox (of course ;)
3798 <p
><strong
>Which strategy do you believe is the right one to use to
3799 get schools to use free software?
</strong
></p
>
3801 <p
>To get schools to use free software there has to be good open
3802 source software that are windows based, to ease the transition. But
3803 it
's also very important that the multimedia support is working
3804 flawlessly. The problems with Youtube, Twitter, Facebook and whatever
3805 will create problems when it comes to both teachers and
3806 students. Economy are also important for schools, so using thin
3807 clients, as long as they have good multimedia support, is a very good
3808 idea. It
's also important that the open source software works even for
3809 the administration. It
's hard to convince the teachers to stick with
3810 open source, if the principal has to run Windows. It also creates a
3811 problem if some classes has to use Windows for there tasks, since that
3812 will create a difference in
"status
" between classes, so a good
3813 support for running windows applications via the thin client (Linux)
3814 desktop is essential. At least at our school, where we have mixed
3815 level of educations, from high-school to journalist-school.

>In the Debian Edu / Skolelinux project, we have realised that one
3835 of the major blockers for the project success is the purchasing skills
3836 in schools and municipalities. We provide what the happy users of
3837 Debian Edu / Skolelinux say they need and to a lower cost than the
3838 alternatives, and yet so few schools decide to use our solution. I
3839 was pleased to discover the same observation done by mySociety and Tom

3845 <p

3846 projects bad marketing skills and the Linux community fragmentation
3847 causing worry with the people on the outside, so we as a project need
3848 to keep working hard to gain users, but it is a up-hill battle when

40 år. Utdannet biolog med ymse
4052 fag på siden. Har jobbet som lærer der jeg var driftsansvarlig på
4053 Ulsrud VGS i Oslo. Senere eide og jobbet jeg flere år i Linuxlabs AS,
4054 som jeg solgte til Redpill Linpro AS (den gangen Linpro AS). I dag
4055 jobber jeg med ulike investeringer, hovedsaklig i eiendom, men også i
4056 en del ulike IT-relaterte bedrifter.

4060 <p
>Fruen og jeg dro på en lengre seiltur i
2000, der jeg måtte ha
"noe
4061 å gjøre
" under hjemturen over Atlanteren. Jeg kjøpte et par bøker om
4062 Linux i en bokhandel i New York og ble veldig fascinert. Etter
4063 hjemkomsten begynte jeg å jobbe på Ulsrud VGS, som naturfagslærer, men
4064 som IT-interessert ble jeg fort en del av den nye IT-satsningen som
4065 skulle løfte Ulsrud og gi skolen en bedre rykte. Vi hadde ganske
4066 mange maskiner, som gikk på Win98 og to servere som ble oppgradert til
4067 Win2000. Systemene var ustabil og dårlige. På leting etter noe
4068 bedre, uten å knekke ryggen økonomisk, kom jeg over
"Linux i Skolen
"
4069 og Skolelinux. Jeg tok kontakt med miljøet og en gjeng møtte opp på
4070 skolen, der vi gjorde en liten testinstallasjon. Etter et par år var
4071 ryggraden på skolen Linux (Skolelinux) og vi hadde flere hundre
4072 maskiner, både tynne klienter (gamle og nye), bærbare (Debian) og noen
4073 stasjonære (Win2000). På et tidspunkt var Ulsrud den råeste IT-skolen
4074 og det irriterte skolesjefen i Oslo, da de satset hardt på

</strong

4079 <p
>Det som gjorde at vi fikk inn Skolelinux var ene og alene
4080 økonomiske. Det faktum at vi slapp å kjøpe masse nye lisenser og at
4081 vi kunne bruke gammel hardware. Alt i alt gjorde dette at vi sparte
4082 mye, men i stede for å bruke mindre på IT brukte vi det vi sparte på å
4083 skaffe mer hardware og på den måten gi det beste tilbudet i landet til
4084 våre elever. For oss som driftet var det himmel å ha et system som
4085 gikk å administrere sentralt og effektivt. Det var heller ikke så
4086 dumt at vi kunne
"låse
" maskinene mer effektivt enn vi kunne med
4087 Microsoft Windows, slik at vi slapp mye feil og problemer som ble
4088 forårsaket av
"kreative
" elever.

4092 <p
>Det vi slet med var mangelen av en del programmer lærerne ville ha.
4093 Husker ikke alle, men det var et knippe med pedagogiske programmer de
4094 ikke fikk. I dag tror jeg det problemet er langt mindre da det meste
4095 av disse kjøres gjennom nettleseren.

4099 <p

4100 både OpenOffice, Firefox og en del andre programmer på den bærbare.
4101 Firefox brukes mest av disse. På Apple-serveren hjemme bruker jeg
4102 HandBrake mye, og jeg har installert OpenWRT på flere av
4103 basestasjonene både hjemme og på jobben. I tillegg til det har jeg i
4104 flere år finansiert et prosjekt som heter
4105 <a href=

">Found IT
</a

4106 vi lager et rammeverk for søk, der alt vi bruker fri programvare. Det

4110 skoler til å ta i bruk fri programvare?

4112 <p
>Når det gjelder IT og skole er fortsatt økonomi veldig viktig. Så
4113 man må oppfylle minimumskravene (ikke være best, men bra nok) og selge
4114 seg inn på hvor mye man sparer. Det betyr selvsagt at man sparer på
4115 lisenser, men også på driftsinnsats. Men nå når jeg ikke er en aktiv
4116 del av miljøet lenger hører jeg nesten ingen ting om fri programvare.
4117 Jeg stiller meg da spørsmålet om det har blitt stille rundt miljøet,
4118 eller om jeg kun så det tydeligere før når jeg var aktiv? Uansett er
4119 det for stille rundt Skolelinux-prosjektet nå.

've been too busy at home, but finally I found time to wrap up
4129 another interview with the people behind
4130 <a href=
"http://www.skolelinux.org/
">Debian Edu and Skolelinux
</a
>.
4131 This time we get to know José Luis Redrejo Rodríguez, one of our great
4132 helpers from Spain. His effort was the reason we added support for
4133 several desktop types (KDE, Gnome and most recently LXDE) in Debian
4134 Edu, and have all of these available in the recently published
4135 <a href=

</p
>
4138 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
4140 <p
>I
'm a father, teacher and engineer who is working for the Education
4141 ministry of the Region of Extremadura (Spain) in the implementation of
4142 ICT in schools
</p
>
4144 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4145 project?
</strong
></p
>
4147 <p
>At
2006, I verified that both, we in Extremadura and Skolelinux
4148 project, had been working in parallel for some years, doing very
4149 similar things, using very similar tools and with similar targets, so
4150 I decided it was time to join forces as much as possible.
</p
>
4152 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4153 Edu?
</strong
></p
>
4155 <p
>A community of highly skilled experts working together, with a
4156 really open schema of collaboration and work. I really love the
4157 concepts of Do-ocracy and Merit-ocracy and the way these concepts are
4158 been used everyday inside Debian Edu.
</p
>
4160 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
4161 Edu?
</strong
></p
>
4163 <p
>Sometimes the differences in the implementations, laws or
4164 economical and technical resources in the different countries don
't
4165 allow us to agree in the same solution for all of us, and several
4166 approaches are needed, what is a waste of effort. Also, there is a
4167 lack of more man power to be able to follow the fast evolution of the
4168 technologies in school.
</p
>
4170 <p
><strong
>Which free software do you use daily?
</strong
></p
>
4172 <p
>Debian, of course, and due to my kind of job I am most of my time
4173 between Iceweasel,
<a href=

">Geany
</a
> and
4174 <a href=
"http://www.ohloh.net/p/gnome-terminator
">Terminator
</a
>.
</p
>
4176 <p
><strong
>Which strategy do you believe is the right one to use to
4177 get schools to use free software?
</strong
></p
>
4179 <p
>I think there is not a single strategy because there are very
4180 different scenarios: schools with mixed proprietary and free
4181 environments, schools using only workstations, other schools using
4182 laptops, netbooks, tablets, interactive white-boards, etc.
</p
>
4184 <p
>Also the range of ages of the students is very broad and you can
4185 not use the same solutions for primary schools and secondary or even
4186 universities. So different strategies are needed.
</p
>
4188 <p
>But, looking at these differences, and looking back to the things
4189 we
've done and implemented, and the places were we have spent most of
4190 our forces, I think we should focus as much as possible in free
4191 multi-platform environments, using only standards tools, and moving
4192 more and more to Internet or network solutions that could be deployed
4193 using wireless. I think we
'll see more and more personal devices in
4194 the schools, devices the students and teachers will take home with
4195 them, so the solutions must be able to be taken at home and continue
4196 working there.

">Debian Edu
4207 based on Squeeze
</a
>, I came across some issues that should be
4208 addressed in the Wheezy release. I finally found time to wrap up my
4209 notes and provide quick summary of what I found, with a bit
4210 explanation.
</p
>
4214 <li
>We need to rewrite our package installation framework, as tasksel
4215 changed from using tasksel tasks to using meta packages (aka packages
4216 with dependencies like our education-* packages), and our installation
4217 system depend on tasksel tasks in
4218 /usr/share/tasksel/debian-edu-tasks.desc for package
4219 installation.
</li
>
4221 <li
>Enable Kerberos login for more services. Now with the Kerberos
4222 foundation in place, we should use it to get single sign on with more
4223 services, and avoiding unneeded password / login questions. We should
4224 at least try to enable it for these services:
4227 <li
>CUPS for admins to add/configure printers and users when using
4229 <li
>Nagios for admins checking the system status.
</li
>
4230 <li
>GOsa for admins updating LDAP and users changing their passwords.
</li
>
4231 <li
>LDAP for admins updating LDAP.
</li
>
4232 <li
>Squid for users when exam mode / filtering is active.
</li
>
4233 <li
>ssh for admins and users to save a password prompt.
</li
>
4235 </ul
></li
>
4237 <li
>When we move GOsa to use Kerberos instead of LDAP bind to
4238 authenticate users, we should try to block or at least limit access to
4239 use LDAP bind for authentication, to ensure Kerberos is used when it
4240 is intended, and nothing fall back to using the less safe LDAP bind
</li
>
4242 <li
>Merge debian-edu-config and debian-edu-install. The split made
4243 sense when d-e-install did a lot more, but these days it is just an
4244 inconvenience when we update the debconf preseeding values.
</li
>
4246 <li
>Fix partman-auto to allow us to abort the installation before
4247 touching the disk if the disk is too small. This is
4248 <a href=
"http://bugs.debian.org/
653305">BTS report #
653305</a
> and the
4249 d-i developers are fine with the patch and someone just need to apply
4250 it and upload. After this is done we need to adjust
4251 debian-edu-install to use this new hook.
</li
>
4253 <li
>Adjust to new LTSP framework (boot time config instead of install
4254 time config). LTSP changed its design, and our hooks to install
4255 packages and update the configuration is most likely not going to work
4258 <li
>Consider switching to NBD instead of NFS for LTSP root, to allow
4259 the Kernel to cache files in its normal file cache, possibly speeding
4260 up KDE login on slow networks.
</li
>
4262 <li
>Make it possible to create expired user passwords that need to
4263 change on first login. This is useful when handing out password on
4264 paper, to make sure only the user know the password. This require
4265 fixes to the PAM handling of kdm and gdm.
</li
>
4267 <li
>Make GUI for adding new machines automatically from sitesummary.
4268 The current command line script is not very friendly to people most
4269 familiar with GUIs. This should probably be integrated into GOsa to
4270 have it available where the admin will be looking for it..
</li
>
4272 <li
>We should find way for Nagios to check that the DHCP service
4273 actually is working (as in handling out IP addresses). None of the
4274 Nagios checks I have found so far have been working for me.
</li
>
4276 <li
>We should switch from libpam-nss-ldapd to sssd for all profiles
4277 using LDAP, and not only on for roaming workstations, to have less
4278 packages to configure and consistent setup across all profiles.
</li
>
4280 <li
>We should configure Kerberos to update LDAP and Samba password
4281 when changing password using the Kerberos protocol. The hook was
4282 requested in
<a href=
"http://bugs.debian.org/
588968">BTS report
4283 #
588968</a
> and is now available in Wheezy. We might need to write a
4284 MIT Kerberos plugin in C to get this.
</li
>
4286 <li
>We should clean up the set of applications installed by default.
4289 <li
>reduce the number of chemistry visualisers
</li
>
4290 <li
>consider dropping xpaint
</li
>
4291 <li
>and probably more?
</li
>
4292 </ul
></li
>
4294 <li
>Some hardware need external firmware to work properly. This is
4295 mostly the case for WiFi network cards, but there are some other
4296 examples too. For popular laptops to work out of the box, such
4297 firmware need to be installed from non-free, and we should provide
4298 some GUI to do this. Ubuntu already have this implemented, and we
4299 could consider using their packages. At the moment we have some
4300 command line script to do this (one for the running system, another
4301 for the LTSP chroot).
</li
>
4304 <li
>In Squeeze, we provide KDE, Gnome and LXDE as desktop options. We
4305 should extend the list to Xfce and Sugar, and preferably find a way to
4306 install several and allow the admin or the user to select which one to
4309 <li
>The golearn tool from the goplay package make it easy to check out
4310 interesting educational packages. We should work on the package
4311 tagging in Debian to ensure it represent all the useful educational
4312 packages, and extend the tool to allow it to use packagekit to install
4313 new applications with a simple mouse click.
</li
>
4315 <li
>The Squeeze version got half a exam solution already in place,
4316 with the introduction of iptable based network blocking, but for it to
4317 be a complete exam solution the Squid proxy need to enable
4318 filtering/blocking as well when the exam mode is enabled. We should
4319 implement a way to easily enable this for the schools that want it,
4320 instead of the
"it is documented
" method of today.
</li
>
4322 <li
>A feature used in several schools is the ability for a teacher to
4323 "take over
" the desktop of individual or all computers in the room.
4324 There are at least three implementations,
4325 <a href=
"italc.sourceforge.net/
">italc
</a
>,
4326 <a href=
"http://www.itais.net/help/en/
">controlaula
</a
> og
4327 <a href=
"http://www.epoptes.org/
">epoptes
</a
> and we should pick one of
4328 them and make it trivial to set it up in a school. The challenges is
4329 how to distribute crypto keys and how to group computers in one room
4330 and how to set up which machine/user can control the machines in a
4331 given room.
</li
>
4333 <li
>Tablets and surf boards are getting more and more popular, and we
4334 should look into providing a good solution for integrating these into
4335 the Debian Edu network. Not quite sure how. Perhaps we should
4336 provide a installation profile with better touch screen support for
4337 them, or add some sync services to allow them to exchange
4338 configuration and data with the central server. This should be
4339 investigated.

4362 <p
>My name is Mike Gabriel, I am
38 years old and live near Kiel,
4363 Schleswig-Holstein, Germany. I live together with a wonderful partner
4364 (Angela Fuß) and two own children and two bonus children (contributed
4365 by Angela).

4371 becoming an osteopath.
</p

4373 <p
>Starting in
2010 we (Andreas Buchholz, Angela Fuß, Mike Gabriel)
4374 have set up a free software project in the area of Kiel that aims at
4375 introducing free software into schools. The project
's name is
4376 "IT-Zukunft Schule
" (IT future for schools). The project links IT
4377 skills with communication skills.

4380 project?
</strong

4382 <p
>While preparing our own customised Linux distribution for
4383 "IT-Zukunft Schule
" we were repeatedly asked if we really wanted to
4384 reinvent the wheel. What schools really need is already available,
4385 people said. From this impulse we started evaluating other Linux
4386 distributions that target being used for school networks.
</p
>
4388 <p
>At the end we short-listed two approaches and compared them: a
4389 commercial Linux distribution developed by a company in Bremen,
4390 Germany, and Skolelinux / Debian Edu. Between
12/
2010 and
03/
2011 we
4391 went to several events and met people being responsible for marketing
4392 and development of either of the distributions. Skolelinux / Debian
4393 Edu was by far much more convincing compared to the other product that
4394 got short-listed beforehand--across the full spectrum. What was most
4395 attractive for me personally: the perspective of collaboration within
4396 the developmental branch of the Debian Edu project itself.
</p
>
4398 <p
>In parallel with this, we talked to many local and not-so-local
4399 people. People teaching at schools, headmasters, politicians, data
4400 protection experts, other IT professionals.
</p
>
4402 <p
>We came to two conclusions:
</p
>
4404 <p
>First, a technical conclusion: What schools need is available in
4405 bits and pieces here and there, and none of the solutions really fit
4406 by
100%. Any school we have seen has a very individual IT setup
4407 whereas most of each school
's requirements could mapped by a standard
4408 IT solution. The requirement to this IT solution is flexibility and
4409 customisability, so that individual adaptations here and there are
4410 possible. In terms of re-distributing and rolling out such a
4411 standardised IT system for schools (a system that is still to some
4412 degree customisable) there is still a lot of work to do here
4413 locally. Debian Edu / Skolelinux has been our choice as the starting
4416 <p
>Second, a holistic conclusion: What schools need does not exist at
4417 all (or we missed it so far). There are several technical solutions
4418 for handling IT at schools that tend to make a good impression. What
4419 has been missing completely here in Germany, though, is the enrolment
4420 of people into using IT and teaching with IT.
"IT-Zukunft Schule
"
4421 tries to provide an approach for this.
</p
>
4423 <p
>Only some schools have some sort of a media concept which explains,
4424 defines and gives guidance on how to use IT in class. Most schools in
4425 Northern Germany do not have an IT service provider, the school
's IT
4426 equipment is managed by one or (if the school is lucky) two (admin)
4427 teachers, most of the workload these admin teachers get done in there
4428 spare time.
</p
>
4430 <p
>We were surprised that only a very few admin teachers were
4431 networked with colleagues from other schools. Basically, every school
4432 here around has its individual approach of providing IT equipment to
4433 teachers and students and the exchange of ideas has been quasi
4434 non-existent until
2010/
2011.
</p
>
4436 <p
>Quite some (non-admin) teachers try to avoid using IT technology in
4437 class as a learning medium completely. Several reasons for this
4438 avoidance do exist.
</p
>
4440 <p
>We discovered that no-one has ever taken a closer look at this
4441 social part of IT management in schools, so far. On our quest journey
4442 for a technical IT solution for schools, we discussed this issue with
4443 several teachers, headmasters, politicians, other IT professionals and
4444 they all confirmed: a holistic approach of considering IT management
4445 at schools, an approach that includes the people in place, will be new
4446 and probably a gain for all.
</p
>
4448 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4449 Edu?
</strong
></p
>
4451 <p
>There is a list of advantages: international context, openness to
4452 any kind of contributions, do-ocracy policy, the closeness to Debian,
4453 the different installation scenarios possible (from stand-alone
4454 workstation to complex multi-server sites), the transparency within
4455 project communication, honest communication within the group of
4456 developers, etc.

4458 <p

4459 Edu?
</strong

4461 <p
>Every coin has two sides:
</p
>
4463 <p
>Technically:
<a href=
"http://bugs.debian.org/
311188">BTS issue
4464 #
311188</a
>, tricky upgradability of a Debian Edu main server, network
4465 client installations on top of a plain vanilla Debian installation
4466 should become possible sometime in the near future, one could think
4467 about splitting the very complex package debian-edu-config into
4468 several portions (to make it easier for new developers to
4469 contribute).
</p
>
4471 <p
>Another issue I see is that we (as Debian Edu developers) should
4472 find out more about the network of people who do the marketing for
4473 Debian Edu / Skolelinux. There is a very active group in Germany
4474 promoting Skolelinux on the bigger Linux Days within Germany. Are
4475 there other groups like that in other countries? How can we bring
4476 these marketing people together (marketing group A with group B and
4477 all of them with the group of Debian Edu developers)? During the last
4478 meeting of the German Skolelinux group, I got the impression of people
4479 there being rather disconnected from the development department of
4480 Debian Edu / Skolelinux.

4484 <p
>For my daily business, I do not use commercial software at all.
</p

4486 <p
>For normal stuff I use Iceweasel/Firefox, Libreoffice.org. For
4487 serious text writing I prefer LaTeX. I use gimp, inkscape, scribus for
4488 more artistic tasks. I run virtual machines in KVM and Virtualbox.

2010 I started the

4492 PyHoca-GUI has brought forth a Python X2Go Client API that currently
4493 is being integrated in Ubuntu

4525 <p
><strong
>Who are you, and how do you spend your days?

></p

4527 <p
>I am a teacher from Germany, and my subjects are Geography,
4528 Mathematics, and Computer Science (
"Informatik
"). During the past
12
4529 years (since
2000), I have been working for a comprehensive (and soon,
4530 also inclusive) school leading to all kind of general levels, such as
4531 O- or A-level (
"Abitur
"). For quite as long, I
've been taking care of
4532 our computer network.
</p
>
4534 <p
>Now, in my early
40s, I enjoy the privilege of spending a lot of my
4535 spare time together with my wife, our son (
3 years) and our daughter
4536 (
4 months).
</p
>
4538 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4539 project?
</strong
></p
>
4541 <p
>We had tried different Linux based school servers, when members of
4542 my local Linux User Group (LUG OWL) detected Skolelinux. I remember
4543 very well, being part of a party celebrating the Linux New Media Award
4544 (
"Best Newcomer Distribution
", also nominated: Ubuntu) that was given
4545 to Skolelinux at Linux World Exposition in Frankfurt,
2005 (IIRC). Few
4546 months later, I had the chance to join a developer meeting in Ulsrud
4547 (Oslo) and to hand out the award to Knut Yrvin and others. For more
4548 than
7 years, Skolelinux is part of our schools infrastructure, namely
4549 our main server (tjener), one LTSP (today without thin clients), and
4550 approximately
50 work stations. Most of these have the option to boot a
4551 locally installed Skolelinux image. As a consequence, I joined quite
4552 a few events dealing with free software or Linux, and met many Debian
4553 (Edu) developers. All of them seemed quite nice and competent to me,
4554 one more reason to stick to Skolelinux.
</p

4556 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4557 Edu?
</strong
></p
>
4559 <p
>Debian driven, you are given all the advantages of a community
4560 project including well maintained updates. Once, you are familiar with
4561 the network layout, you can easily roll out an entire educational
4562 computer infrastructure, from just one installation media. As only
4563 free software (FOSS) is used, that supports even elderly hardware,
4564 up-sizing your IT equipment is only limited by space (i.e. available
4565 labs). Especially if you run a LTSP thin client server, your
4566 administration costs tend towards zero.
</p
>
4568 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
4569 Edu?
</strong
></p
>
4571 <p
>While Debian
's stability has loads of advantages for servers, this
4572 might be different in some cases for clients: Schools with unlimited
4573 budget might buy new hardware with components that are not yet
4574 supported by Debian stable, or wish to use more recent versions of
4575 office packages or desktop environments. These schools have the
4576 option to run Debian testing or other distributions - if they have the
4577 capacity to do so. Another issue is that Debian release cycles
4578 include a wide range of changes; therefor a high percentage of human
4579 power seems to be absorbed by just keeping the features of Skolelinux
4580 within the new setting of the version to come. During this process,
4581 the cogs of Debian Edu are getting more and more professional,
4582 i.e. harder to understand for novices.
</p

4584 <p
><strong
>Which free software do you use daily?
</strong
></p
>
4586 <p
>LibreOffice, Wikipedia, Openstreetmap, Iceweasel (Mozilla Firefox),
4587 KMail, Gimp, Inkscape - and of course the Linux Kernel (not only on
4588 PC, Laptop, Mobile, but also our SAT receiver)
</p
>
4590 <p
><strong
>Which strategy do you believe is the right one to use to
4591 get schools to use free software?
</strong
></p
>
4595 <li
>Support computer science as regular subject in schools to make
4596 people really
"own
" their hardware, to make them understand the
4597 difference between proprietary software products, and free software
4598 developing.
</li
>
4600 <li
>Make budget baskets corresponding: In Germany
's public schools
4601 there are more or less fixed budgets for IT equipment (including
4602 licenses), so schools won
't benefit from any savings here. This
4603 privilege is left to private schools which have consequently a large
4604 share among German Skolelinux schools.
</li
>
4606 <li
>Get free software in the seminars where would-be teachers are
4607 trained. In many cases, teachers
' software customs are respected by
4608 decision makers rather than the expertise of any IT experts.
</li
>
4610 <li
>Don
't limit ourself to free software run natively. Everybody uses
4611 free software or free licenses (for instance Wikipedia), and this
4612 general concept should get expanded to free educational content to be
4613 shared world wide (school books e.g.).
</li
>
4615 <li
>Make clear where ever you can that the market share of free (libre)
4616 office suites is much above
20 p.c. today, and that you pupils don
't
4617 need to know the
"ribbon menu
" in order to get employed.
</li
>
4619 <li
>Talk about the difference between freeware and free software.
</li
>
4621 <li
>Spread free software, or even collections of portable free apps
4622 for USB pen drives. Endorse students to get a legal copy of
4623 Libreoffice rather than accepting them to use illegal serials. And
4624 keep sending documents in ODF formats.

4649 etter at ryggen sa takk før seg, studerte jeg nettverksadministrasjon
4650 ved Næringsakademiet i Bergen årene

4656 <p
>Mitt mål er å bevisstgjøre musikklærene mulighetene med de frie
4657 programmene som finnes i Skolelinux, blant annet Rosegarden.
</p
>
4659 <p
>Har i mange år drevet med musikk og en av grunnen til at Rosegarden
4660 falt i smak for min del, var fordi denne fungere og ligner mest på
4661 Windows-programmet (cubase) jeg jobbet mye med da jeg i mine yngre
4662 dager var «Windows fanatiker». Ble introdusert til Linux av en kompis
4663 av meg for omtrent
14 år siden, og har bare blitt mer og mer glad i

4671 Skolelinuxprosjektet.

>
4673 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p

4675 <p
>Skolelinux er enkelt å holde i drift og masse flotte programmer som
4676 geogebra, ktouch og kgeografi følger med pakken. Man kan ta i bruk
4677 gamle PC-er igjen, slik at skoler med dårlig råd får opp en brukbar
4678 PC-park. PC-er som er ca
6-
9 år gamle fungere tilfredstillende, bare
4679 de har
512 MB RAM eller mer.
</p
>
4681 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
4683 <p
>Ulempene er at noen av de pedagogiske programmene som lærene ønsker
4684 å bruke fungere dårlig med Linux. Mye pga. av at disse programmene
4685 blir ikke laget til Linuxbaserte operativsystemer.
</p
>
4687 <p
>Video- og bilde-redigering har dessverre en del mangler, mange av
4688 programmene har en tendens til og krasje. Det gjelder blant annet
4689 <a href=
"http://www.kdenlive.org/
">kdenlive
</a
> og
4690 <a href=
"http://www.openshotvideo.com/
">openshot
</a
>, for å nevne
4691 noen. De er ikke stabile nok. Når elevene kommer med filmsnutter de
4692 ønsker og jobbe med, så godtar ikke programmene filene, og når elevene
4693 jobber med redigering bare krasjer programmene uten forvarsel. Det er
4694 for vanskelig å få noe som bare fungerer ut av boksen her. Når en elev
4695 plugger inn et videokamera eller fotoapparat så er det alltid noe som
4696 ikke vil fungere. Programmene godtar ikke format, godtar ikke
4697 kameraet, osv., osv. Det er dessverre med på og dra ned en positiv
4698 opplevelse av bruk av fri programvare.
</p
>
4700 <p
>Man må ofte bruke flere en et video redigerings program før og få
4701 fullført en ønsket oppgave.
</p
>
4703 <p
>Eksempel:
</p
>
4705 <p
>Hvis det ene programmet ikke vil ta i mot videofilen klarer et
4706 annet det, men det programmet som klarer det kan ikke gjøre de samme
4707 oppgavene som det programmet som ikke ville ta i mot filen,
4708 Tilsvarende er det med foto, man må bruke flere programmer for å få
4709 et ferdig resultat. Til dags dato har jeg enda ikke funnet et video-
4710 og fotoprogram som kan tilfredstillende fullføre en oppgave.
</p
>
4712 <p
>Så man kan klare og fullføre en oppgave, men i verste fall må man
4713 innom
3-
4 programmer for å få det til. Så jeg har enda ikke til dags
4714 dato sett at et program fungere
100% til alt.
</p
>
4716 <p
>Det programmet jeg har best erfaring til er
4717 <a href=
"http://cinelerra.org/
">cinelerra
</a
>, men dessverre har det
4718 også tendenser og krasje av og til uten grunn.
</p
>
4720 Lydsystemet kan også være et mareritt. Konkret snakker jeg om når du
4721 bruker for eksempel et smartboard, så følger det med USB-lydkort på
4722 disse. Problemet ligger her i at systemet ikke vil velge rett
4723 lydkort, så man må inn med padevchooser for å sette opp PulseAudio
4724 til og velge at USB-lydkortet skal brukes. Det blir for tungvindt for
4725 lærene, de ønsker at ting skal fungere med en gang. (min løsning på
4726 det problemet ble at jeg måtte deaktivere lydkortet som fantes på
4727 maskinen) men da må man bestandig slå på smartboard-tavla.
4729 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
4731 Programmene jeg bruker mest av er: Rosegarden, jack, qsynth, audacity,
4732 k3b, openttd og libreoffice.
4734 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
4735 skoler til å ta i bruk fri programvare?

4737 Jeg tror det må bevisstgjøring av Skolene til, dvs. reklamere høylytt
4738 og fortelle og vise de andre skolene at frie programvarer faktisk
4739 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
4750 publish another interview with the people behind
4751 <a href=
"http://www.skolelinux.org/
">Debian Edu and Skolelinux
</a
>.
4752 This time it is one of our German developers, who have helped out over the
4753 years to make sure both a lot of major but also a lot of the minor
4754 details get right before release.
4756 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
4758 <p
>My name is Jürgen Leibner, I
'm
49 years old and living in
4759 Bielefeld, a town in northern Germany. I worked nearly
20 years as
4760 certified engineer in the department for plant design and layout of an
4761 international company for machinery and equipment. Since
2011 I
'm a
4762 certified technical writer (tekom e.V.) and doing technical
4763 documentations for a steam turbine manufacturer. From April this year
4764 I will manage the department of technical documentation at a
4765 manufacturer of automation and assembly line engineering.
</p
>
4767 <p
>My first contact with linux was around
1993. Since that time I used
4768 it at work and at home repeatedly but not exclusively as I do now at
4769 home since
2006.
</p
>
4771 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4772 project?
</strong
></p
>
4774 <p
>Once a day in the early year of
2001 when I wanted to fetch my
4775 daughter from primary school, there was a teacher sitting in the
4776 middle of
20 old computers trying to boot them and he failed. I helped
4777 him to get them booting. That was seen by the school director and she
4778 asked me if I would like to manage that the school gets all that old
4779 computers in use. I answered:
"Yes
".
</p
>
4781 <p
>Some weeks later every of the
10 classrooms had one computer
4782 running Windows98. I began to collect old computers and equipment as
4783 gifts and installed the first computer room with a peer-to-peer
4784 network. I did my work at school without being payed in my spare time
4785 and with a lot of fun. About one year later the school was connected
4786 to Internet and a local area network was installed in the school
4787 building. That was the time to have a server and I knew it must be a
4788 Linux server to be able to fulfil all the wishes of the teachers and
4789 being able to do this in a transparent and economic way, without extra
4790 costs for things like licence and software. So I searched for a
4791 school server system running under Linux and I found a couple of
4792 people nearby who founded
'skolelinux.de
'. It was the Skolelinux
4793 prerelease
32 I first tried out for being used at the school. I
4794 managed the IT of that school until the municipal authority took over
4795 the IT management and centralised the services for all schools in
4796 Bielefeld in December of
2006.

><strong
>What do you see as the advantages of Skolelinux/Debian
4799 Edu?
</strong

>
4801 <p
>When I
'm looking back to the beginning, there were other advantages
4802 for me as today.
</p

>Da jeg googlet etter noe annet kom jeg tilfeldigvis over
4902 <a href=
"http://www.duo.uio.no/sok/work.html?WORKID=
58309">en
4903 hovedfagsoppgave
</a
> ved Universitetet i Oslo som diskuterer verdien
4904 av GPLs fire friheter for brukerne av IT-systemer. Jeg ble fascinert
4905 over det som presenteres der. Her er sammendraget:
</p
>
4907 <p
><blockquote
>
4909 <p
>Motivasjonen til å skrive denne oppgaven er en personlig undring
4910 over hvorfor det primært, og ofte eksklusivt, fokuseres på det
4911 økonomiske aspektet ved utredninger om fri programvare er et godt valg
4912 for det offentlige. Fri og produsenteid programvare bygger på
4913 fundamentalt forskjellige ideologier som kan ha implikasjoner utover
4914 økonomiske kostnader. Kunnskapskulturen som er med på å definere fri
4915 programvare er basert på åpenhet, og er en verdi i seg selv.
</p
>
4917 <p
>Oppgavens tema er programvarelisensen GPL og frihet. GPL-lisensiert
4918 programvare gir visse friheter i forhold til produsenteid
4919 programvare. Mitt spørsmål er om, og eventuelt i hvilken utstrekning,
4920 disse frihetene blir benyttet av ulike brukere og hvordan de
4921 manifesterer seg for disse brukerne. Sentrale spørsmål i oppgaven
4925 <li
>Hvordan fordeles handlekraft gjennom lisensieringen av programvaren?
</li
>
4926 <li
>Hvilke konsekvenser har programvarelisensen for de ulike brukere?
</li
>
4929 <p
>Fri programvare gir blant annet brukeren mulighet til å studere og
4930 modifisere kildekoden. Denne formen for frihet erverves gjennom
4931 kunnskap og krever at brukeren også er en ekspert. Hva skjer med
4932 frihetene til GPL når sluttbrukeren er en annen? Dette diskuteres i
4933 dialog med informantene.
</p
>
4935 <p
>Jeg har i denne oppgaven samlet inn intervjudata fra IKT-ansvarlige
4936 ved grunnskolene i Nittedal kommune, driftsansvarlig og IKT-veilederen
4937 for skolene i kommunen, samt IKT-koordinator for utdanning i Akershus
4938 fylkeskommune og bokmåloversettere av OpenOffice.org. Den empiriske
4939 delen av oppgaven er delt inn i to seksjoner; den første omhandler
4940 operativsystemet Skolelinux, den andre kontorprogrampakken
4941 OpenOffice.org.
</p
>
4943 <p
>Som vi vil se gir GPL lokal frihet og kontroll gjennom omfordeling
4944 av makt fra produsent til bruker. Brukerens makt analyseres gjennom
4945 begrepene brukermedvirkning og handlingsfrihet. Det blir også lagt
4946 vekt på strukturelle forhold rundt bruken av teknologi, og spesielt de
4947 økonomiske begrepene nettverkseksternaliteter, innlåsing og
4948 stiavhengighet. Dette er begreper av spesiell nytte når objektet som
4949 omsettes eller distribueres er et kommunikasjonsprodukt, fordi verdien
4950 til et slikt gode for en potensiell bruker avhenger av antall
4951 eksisterende brukere av godet. I tilknytning til denne problematikken
4952 inneholder oppgaven også en diskusjon rundt åpne standarder og
4955 <p
>Oppgaven konkluderer med at de «fire frihetene» som GPL-lisensen er
4956 laget for å beskytte er av avgjørende betydning for bruken av
4957 OpenOffice.org og Skolelinux, i Akershus fylkeskommune såvel som i
4958 skolene i Nittedal. Distribusjonen av handlekraft er ikke helt
4959 symmetrisk. Det er først og fremst de profesjonelle utviklerne i
4960 Skolelinux som direkte kan nyttiggjøre seg friheten til å endre kode,
4961 mens en sluttbruker som Nittedal kommune nyttiggjør seg den økonomiske
4962 friheten til å kunne distribuere programmene. Det er imidlertid også
4963 slik at ingen aktør klarer seg uten alle disse «frihetene».

<a href=

">Debian Edu and
4980 Skolelinux
</a
> there are a lot of people doing the hard work of
4981 setting together all the pieces. This time I present to you Andreas
4982 Mundt, who have been part of the technical development team several
4983 years. He was also a key contributor in getting GOsa and Kerberos set
4984 up in the recently released
4985 <a href=

4988 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
4990 <p
>My name is Andreas Mundt, I grew up in south Germany. After
4991 studying Physics I spent several years at university doing research in
4992 Quantum Optics. After that I worked some years in an optics company.
4993 Finally I decided to turn over a new leaf in my life and started
4994 teaching
10 to
19 years old kids at school. I teach math, physics,
4995 information technology and science/technology.
</p
>
4997 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4998 project?
</strong
></p
>
5000 <p
>Already before I switched to teaching, I followed the Debian Edu
5001 project because of my interest in education and Debian. Within the
5002 qualification/training period for the teaching, I started
5003 contributing.
</p
>
5005 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5006 Edu?
</strong
></p
>
5008 <p
>The advantages of Debian Edu are the well known name, the
5009 out-of-the-box philosophy and of course the great free software of the
5010 Debian Project!
</p
>
5012 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
5013 Edu?
</strong
></p
>
5015 <p
>As every coin has two sides, the out-of-the-box philosophy has its
5016 downside, too. In my opinion, it is hard to modify and tweak the
5017 setup, if you need or want that. Further more, it is not easily
5018 possible to upgrade the system to a new release. It takes much too
5019 long after a Debian release to prepare the -Edu release, perhaps
5020 because the number of developers working on the core of the code is
5021 rather small and often busy elsewhere.
</p
>
5023 <p
>The
<a href=
"http://wiki.debian.org/DebianLAN
">Debian LAN
</a
>
5024 project might fill the use case of a more flexible system.
</p
>
5026 <p
><strong
>Which free software do you use daily?
</strong
></p
>
5028 <p
>I am only using non-free software if I am forced to and run Debian
5029 on all my machines. For documents I prefer LaTeX and PGF/TikZ, then
5030 mutt and iceweasel for email respectively web browsing. At school I
5031 have Arduino and Fritzing in use for a micro controller project.
</p
>
5033 <p
><strong
>Which strategy do you believe is the right one to use to
5034 get schools to use free software?
</strong
></p
>
5036 <p
>One of the major problems is the vendor lock-in from top to bottom:
5037 Especially in combination with ignorant government employees and
5038 politicians, this works out great for the
"market-leader
". The school
5039 administration here in Baden-Wuerttemberg is occupied by that vendor.
5040 Documents have to be prepared in non-free, proprietary formats. Even
5041 free browsers do not work for the school administration. Publishers
5042 of school books provide software only for proprietary platforms.
</p
>
5044 <p
>To change this, political work is very important. Parts of the
5045 political spectrum have become aware of the problem in the last years.
5046 However it takes quite some time and courageous politicians to
'free
'
5047 the system. There is currently some discussion about
"Open Data
" and
5048 "Free/Open Standards
". I am not sure if all the involved parties have
5049 a clue about the potential of these ideas, and probably only a
5050 fraction takes them seriously. However it might slowly make free
5051 software and the philosophy behind it more known and popular.

5118 <a href=

">Skolelinux Drift AS
</a
> on speeding
5119 up a
<a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>
5120 Lenny installation using LTSP diskless workstations, and in the
5121 process I discovered something very surprising. The reason the KDE
5122 menu was responding slow when using it for the first time, was mostly
5123 due to the way KDE find application icons. I discovered that showing
5124 the Multimedia menu would cause more than
20 000 IP packages to be
5125 passed between the LTSP client and the NFS server. Most of these were
5127 NFS LOOKUP calls, resulting in a NFS3ERR_NOENT response. Because the
5128 ping times between the client and the server were in the range
2-
20
5129 ms, the menus would be very slow. Looking at the strace of kicker in
5130 Lenny (or plasma-desktop i Squeeze - same problem there), I see that
5131 the source of these NFS calls are access(
2) system calls for
5132 non-existing files. KDE can do hundreds of access(
2) calls to find
5133 one icon file. In my example, just finding the mplayer icon required
5134 around
230 access(
2) calls.
</p
>
5136 <p
>The KDE code seem to search for icons using a list of icon
5137 directories, and the list of possible directories is large. In
5138 (almost) each directory, it look for files ending in .png, .svgz, .svg
5139 and .xpm. The result is a very slow KDE menu when /usr/ is NFS
5140 mounted. Showing a single sub menu may result in thousands of NFS
5141 requests. I am not the first one to discover this. I found a
5142 <a href=
"https://bugs.kde.org/show_bug.cgi?id=
211416">KDE bug report
5143 from
2009</a
> about this problem, and it is still unsolved.
</p
>
5145 <p
>My solution to speed up the KDE menu was to create a package
5146 kde-icon-cache that upon installation will look at all .desktop files
5147 used to generate the KDE menu, find their icons, search the icon paths
5148 for the file that KDE will end up finding at run time, and copying the
5149 icon file to /var/lib/kde-icon-cache/. Finally, I add symlinks to
5150 these icon files in one of the first directories where KDE will look
5151 for them. This cut down the number of file accesses required to find
5152 one icon from several hundred to less than
5, and make the KDE menu
5153 almost instantaneous. I
'm not quite sure where to make the package
5154 publicly available, so for now it is only available on request.
</p
>
5156 <p
>The bug report mention that this do not only affect the KDE menu
5157 and icon handling, but also the login process. Not quite sure how to
5158 speed up that part without replacing NFS with for example NBD, and
5159 that is not really an option at the moment.

5212 <p
>The first information about Skolelinux must have come to my
5213 attention years ago and somehow related to LTSP (Linux Terminal Server
5214 Project). At school, we had set up a network at the beginning of
1997
5215 using Suse Linux on the desktop, replacing a Novell network. Since
5216 2002, we used old machines from the city council of Dortmund as thin
5217 clients (LTSP, later Ubuntu/Lessdisks) cause new hardware was out of
5218 reach. At home I
'm using Debian since years and - subscribed to the
5219 Debian news letter - heard from time to time about Skolelinux. About
5220 two years ago I proposed to replace the (somehow undocumented and only
5221 known to me) system at school by a well known Debian based system:
5222 Skolelinux.
</p
>
5224 <p
>Students and teachers appreciated the new system because of a
5225 better look and feel and an enhanced access to local media on thin
5226 clients. The possibility to alter and/or reset passwords using a GUI
5227 was welcomed, too. Being able to do administrative tasks using a GUI
5228 and to easily set up workstations using PXE was of very high value for
5229 the admin teachers.
</p

5231 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5232 Edu?
</strong
></p
>
5234 <p
>It
's open source, easy to set up, stable and flexible due to it
's
5235 Debian base. It integrates LTSP out-of-the-box. And it is documented!
5236 So it was a perfect choice.
</p
>
5238 <p
>Being open source, there are no license problems and so it
's
5239 possible to point teachers and students to programs like
5240 OpenOffice.org, ViewYourMind (mind mapping) and The Gimp. It
's of
5241 high value to be able to adapt parts of the system to special needs of
5242 a school and to choose where to get support for this.

5244 <p

>What do you see as the disadvantages of Skolelinux/Debian
5245 Edu?
</strong

>
5247 <p
>Nothing yet.
</p
>
5249 <p
><strong
>Which free software do you use daily?
</strong
></p
>
5251 <p
>At home (Debian Sid with Gnome Desktop): Iceweasel, LibreOffice,
5252 Mutt, Gedit, Document Viewer, Midnight Commander, flpsed (PDF
5253 Annotator). At school (Skolelinux Lenny): Iceweasel, Gedit,
5254 LibreOffice.
</p
>
5256 <p
><strong
>Which strategy do you believe is the right one to use to
5257 get schools to use free software?
</strong
></p
>
5259 <p
>Some time ago I thought it was enough to tell people about it. But
5260 that doesn
't seem to work quite well. Now I concentrate on those more
5261 interested and hope to get multiplicators that way.

5279 <p
>Det er store forskjeller på skolenes digitale tilstand, viser
5280 undersøkelsen Monitor
2011 som er laget på oppdrag fra
5281 Kunnskapsdepartementet. Dette har ført til debatt om PC-tilgangen i
5282 skolen, og om de med Linux i skolen gjør det bedre bedre eller
5283 dårligere enn snittet i landet.
</p
>
5285 <p
>Nå har vi tallene. Skoler med Linux har
36% større PC-tetthet en
5286 landsgjennomsnittet. På spørsmål hvorfor skoler med Linux har større
5287 PC-tetthet, observerer Paul Reidar Løsnesløkken som er IKT-konsulent i
5288 Nord-Odal:
</p
>
5290 <p
><blockquote
>"Vi erfarer at klienter med Skolelinux har god funksjon
5291 til de er
8 til
10 år gamle. Dette er omtrent dobbelt så lenge som
5292 andre løsninger, og skolene får mer datautstyr for
5293 pengene.
"</blockquote
></p
>
5295 <p
>Undersøkelsen baserer seg på
56 skoler som har gjort det offentlig
5296 at de kjører Skolelinux eller annen Linux-utgave. De kan også ha PC-er
5297 med Windows i skolenettet. Når en sammenligner PC-tetthetene på
5298 skolene i kommunene Flora, Harstad, Kongsvinger, Narvik, Nittedal,
5299 Nord-Odal og Randaberg, er det i snitt
2,
28 elev pr. PC på skolene med
5300 Linux. På landsbasis er det
3.11 elev per PC i grunnskolen, i følge
5301 side
95 i Monitor-rapporten for
2011. Målingen viser dermed
36% større
5302 PC-tetthet i skoler med Linux.

</strong

5306 <p
>Skolelinux har til hensikt å gi alle barn full tilgang til
5307 skoleaktuelle dataprogram på sitt eget morsmål. Derfor følger det med
5308 godt over
100 skoleaktuelle programmene laget for læring. De fleste
5309 programmene er oversatt til over
50 språk. Elevene skal også kunne
5310 studere alle sider av dataprogrammene. Derfor følger også kildekode
5311 med. Elever med interesse kan lære av eksperter som har laget
5312 systemet. Dette med enkelt programmering i læreprogram som KTurtle,
5313 til profesjonelle verktøy som Qt Creator eller Java.
</p
>
5315 <p
>Skolelinux er laget for sentralisert drift, der alt teknisk
5316 administrasjon av alle skolene kan gjøres sentralt fra kommunehuset
5317 eller sentralt i en region. F.eks. drifter to-tre personer
70.000
5318 skoledatamaskiner på
200 skoler i delstaten Extremadura i
5319 Spania. Etter velykket bruk av Debian Edu i skolen, legger delstaten
5320 over til Debian på
40.000 datamaskiner i administrasjonen. Det er idag
5321 mange selskap som tilbyr profesjonell støtte til innføring og drift i
5322 Norge og verden.

5359 <description><p
>I serien med intervjuer av folk i
5360 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet, får vi
5361 denne gangen høre fra en IKT-ansvarlig som har brukt Skolelinux i
5362 mange år, og vært storfornøyd med erfaringene så langt.
</p
>
5364 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
5366 <p
>Mitt navn er Roy-Arne Myhre og jeg er
42 år. Jeg er ansatt hos
5367 <a href=
"http://www.sandskole.no/
">Sand skole
</a
> (Balsfjord kommune)
5368 og har stort sett vært det siden
1990. Jeg er IKT ansvarlig ved
5369 skolen i
40% stilling –
10% undervisning – musikk.
</p
>
5371 <p
>Ved skolen er det ca
100 elever og ca
18 lærere +
4 assistenter i
5372 hele og delte stillinger. Alle lærerne har bærbar PC (dessverre med
5373 Win Vista) – assistenter har tilgang til egne. Vi benytter Fronter i
5374 det daglige arbeidet. Vi har ca
90 elevmaskiner som fungerer til
5375 daglig opp mot Linux server (XFCE) som driftes av
5376 <a href=
"http://www.bzz.no/
">BzzWare AS
</a
> via nett. Maskinparken
5377 består kun av brukt utstyr for elevene – og noe av dette begynner å
5378 bli vel gammelt selv som halvtykke klienter.
</p
>
5380 <p
><strong
>Hvordan kom du i kontakt med
5381 Skolelinux-prosjektet?
</strong
></p
>
5383 <p
>Vi kom første gang i kontakt med Skolelinux rundt
1997. Den gang
5384 var det oppstart-disketter i hver maskin, ikke mulighet for lyd og
5385 video, gamle nettverkskort og mye plundring. Vi hadde en ihuga
5386 forelder med som pådriver, forsker og inspirator for hele opplegget.
5387 Selv ante jeg knapt at Skolelinux fantes, men han var av den
5388 utforskende typen, og fikk både meg og skolelederen i trua på at dette
5389 var ting som kunne fungere. Etter dette har det gått gradvis
5390 framover; flere maskiner er hentet inn gjennom bl.a
5391 <a href=
"http://www.greentech.no/
">Greentech
</a
> og utrangert utstyr
5392 fra høgskole / Avinor og private givere. Når maskinene ble for trege
5393 for nye Windows-versjoner, sto vi klare til å putte dem i nettverket
5394 vårt. Dette betyr at vi i dag har
1:
1 dekning av maskiner på
5395 ungdomstrinnet og bedre enn
1:
2 på barnetrinnet. Dette er vi veldig
5396 fornøyd med, og vi kan ikke se for oss hverdagen som ville vært
5397 alternativet ved bruk av Windows med sine lisenser pr. Bruker/maskin.
5398 Da ville vi nok vært tilbake til
1-
2 maskiner pr klasserom med de
5399 negative konsekvenser det ville hatt for undervisningsformene våre. Vi
5400 kan ha en hel klasse i prosjektjobbing eller individuell jobbing
5401 samtidig – vi kan avholde tentamen og eksamen uten
5402 logistikkproblemer.
</p
>
5404 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
5406 Hvor skal jeg begynne... Stabiliteten er et nøkkelord - det bare
5407 virker. Har du først fått en server med Skolelinux opp og gå, så må
5408 det en maskinarefeil eller sabotasje til for å stoppe den. Det at man
5409 kan bruke eldre maskiner som normalt sett ville gått på dynga, er også
5410 glimrende - billig for skoler med dårlig økonomi og bra for miljøet
5411 siden vi gjenbruker utstyr i stedet for å skaffe nytt. Vi ville aldri
5412 hatt mulighet til å operere med det maskinantallet vi har pr i dag
5413 hvis det ikke var for Skolelinux - så tilgjengelighet er et annet
5414 nøkkelord. Et tredje moment er sikkerhet og brukertilgang. Alle
5415 brukerer opererer med egne brukernavn og passord, samt egne
5416 brukerområder som kan tilpasses for både enbrukertilgang og for
5417 samarbeid med andre.
5419 Elever har godt av å se at det finnes andre alternativer enn de som
5420 storindustrien selger på lisensbasis - på den måten trenes de opp til
5421 å se flere muligheter og å foreta valg ut fra flere opsjoner.
5423 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
5425 <p
>Ulempene med Skolelinux er nok utbredelsen og mangelen på kjennskap
5426 til dette i skolenorge. De som skal ta økonomiske avgjørelser rynker
5427 på nesen og vil gå for det kjente og «sikre» selv om det koster mye
5428 mer. Man får rett og slett litt hetta av å ikke kunne noe – og unngår
5429 dette for enhver pris.
</p
>
5431 <p
>I tillegg er mye av linux-systemet administrert av tekstkommandoer
5432 og er lite intuitiv/visuell for oss som ikke er «inne i»
5433 kildekodene». Så problemet er nok mye godt at de som
5434 utarbeider/drifter Skolelinux ikke helt klarer å sette seg ned på
5435 skoleadministratorens nivå når det gjelder problemer og
5436 utfordringer. Men dette er nok en utfordring alle administratorer
5437 sliter med uansett OS.
</p
>
5439 <p
>Derfor har vi valgt å støtte oss til BzzWare AS for assistanse i
5440 drifta slik at jeg har kunnet konsentrere meg mer om kabling, skifting
5441 av komponenter, veiledning av lærere og elever, vedlikehold av
5442 skrivere og annen daglig drift.
</p
>
5444 <p
>Elevene mestrer Skolelinux helt fint. Så lenge Internett
5445 (Iceweasel) og Libreoffice (Openoffice) fungerer er
90% av
5446 skolehverdagen velfungerende. I tillegg brukes jo en del av den
5447 pedagogiske programpakken bla. i forhold til matematikk og geografi,
5448 men det er såpass mye bra på nett om dagen, så disse programmene er
5449 mer som krydder å regne.
</p
>
5451 <p
>Jeg skulle ønske neste versjon av Skolelinux kunne komme litt
5452 mindre stappet med programmer, for halvparten blir aldri brukt, eller
5453 fungerer ikke uansett. Hva med et pedagogisk panel av lærere/IKT
5454 ansvarlige som kunne sagt: disse programmene skal være standard, så
5455 får resten være slike man kan legge til ved behov – det kan lett bli
5456 en jungel å bevege seg i.
</p
>
5458 <p
>Jeg ønsker meg også en mer grafisk versjon av
5459 <a href=
"http://bzz.no/lwat/trac/trac.cgi
">Lwat
</a
> hvor man kan krysse
5460 ut de som f.eks ikke skal ha internett-tilgang en dag pga
5461 eksamen/tentamen, samt en noe enklere brannmurløsning hvor man kan
5462 stenge for en del (få) sider på en enkel måte. Jeg liker godt
5463 Skolelinux sin ideologi om at filteret skal trenes i hodet på eleven –
5464 men av og til skulle jeg ønske at f.eks Facebook og Youtube kunne vært
5465 koblet vekk en periode for å få bedre utnyttelse av tid og
5466 ressurser. Disse to nettstedene er nok mye av årsaken til at mange
5467 lærere holder igjen databruken noe mer enn man kunne ønske.
</p
>
5469 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
5471 Jeg benytter nesten bare fri programvare til daglig. LibreOffice,
5472 Iceweasel (Firefox), Thunderbird til e-post og Gimp til
5473 bildebehandling. Vi har PHP-Nuke-oppsatt hjemmeside. Det eneste som
5474 jeg ikke har fått helt til enda er videoredigering - her må man vel
5475 innrømme at Mac er hakket over, men da er vi igjen over på å se hva
5476 som egner seg best, og ta valg ut fra det. Folk flest lever i
5477 villfarelsen om at regneark HETER Excel og tekstbehandling HETER
5478 Word. Dette er en misforståelse som jeg bruker mye energi på å
5479 diskutere og
"åpne sinn
" på Microsoft-slaver. Dessverre er det mange
5480 IKT-ansvarlige som også har låst seg på at det eneste saliggjørende er
5481 Bill G sine produkter.
5483 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
5484 skoler til å ta i bruk fri programvare?
</strong
></p
>
5486 <p
>For å komme lenger i utbredelsen av Skolelinux tror jeg det må mer
5487 fram i nasjonale medier, samt komme bedre fram hva økonomien i dette
5488 valget vil være – samt mulighetene. Fri programvare er en berikelse og
5489 gjør oss i stand til å utføre arbeidet i skolen uten å måtte legge
5490 igjen tusener på tusener i Bill Gates lomme.. Få ETT nettsted med
5491 forståelig veiledning av installasjon/oppgradering og ETT forum med
5492 konkrete feilrettinger og problemer, så tror jeg vi kunne kommet et
5493 par skritt framover. Ellers tror jeg bare at ildsjelene må fortsette å
5494 skinne – kanskje flere enn oss følger etter på veien.

>Den siste uka har det vært en del skriverier om hvor store
5529 forskjeller det er mellom skolene når det gjelder digital kompetanse.

"http://www.digi.no/

">oppslaget
5532 i Digi
</a
>. Diskusjonen fikk meg til å bli litt nysgjerrig på om
5533 Linux-skoler har større PC-tettet enn snittet i landet. Grunnlaget
5534 for diskusjonen har vært undersøkelsen
5535 <a href=
"https://iktsenteret.no/ressurser/monitor-
2011-skolens-digitale-tilstand
">Monitor
5536 2011</a
>, som bruker informasjon fra
5537 <a href=
"https://www.wis.no/gsi
">Grunnskolens Informasjonssystem
</a
>
5538 (GSI). GSI-data kan lastes ned fra web og jeg lastet ned en Excel-fil
5539 (intet åpen standard-valg tilgjengelig) med navn på alle skoler,
5540 hvilke kommune de befinner seg i og hvor mange elever pr. elev-PC de
5541 har rapportert inn. For å få en ide om svaret trenger jeg deretter å
5542 vite hvilke skoler i landet som bruker Linux, slik at jeg kan slå dem
5543 opp i GSI og finne ut hvor stor PC-tetthet de har.
</p
>
5545 <p
>Jeg vet om skoler i Balsfjord, Flora, Harstad, Kongsvinger, Narvik,
5546 Nittedal, Nord-Odal, Randaberg og Sunndal som bruker Skolelinux eller
5547 andre Linux-varianter. Jeg tror det er flere enn de
56 skolene jeg
5548 har klart å identifisere de siste dagene, men har ikke klart å få det
5549 bekreftet med offentlige kilder.
</p
>
5551 <p
>Monitor
2011-rapporteres side
95 forteller at det
"ifølge GSI
5552 (
20120-
2011) er det
3,
11 elever per datamaskin når vi tar med alle
5553 grunnskoler (
1.-
10.trinn)
". For de
56 Linux-skolene jeg har klart å
5554 koble mot informasjon i GSI er det
2,
28 elever per elevdatamaskin,
5555 hvilket betyr at det er
36% høyere PC-tetthet på Linux-skoler enn
5556 landsgjennomsnittet. Linux-skolen med høyest tettet blant de jeg har
5557 notert -skole er Flora ungdomsskule i Flora kommune med
0.82 elev
5558 pr. PC (
482 elever,
588 elevdatamaskiner).
</p

5560 <p
>Skolelinux gir datamaskiner lengre levetid, og en kan dermed få
5561 flere operative datamaskiner for samme budsjett, i tillegg til en
5562 rekke andre fordeler. Kan det være forklaringen på forskjellen?

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

5587 <p
>I teach ICT part time at the Rudolf Steiner School in Kings
5588 Langley, near London, UK. Previously I worked as a technical
5589 author/trainer while my children attended the school, and I also
5590 contributed to the Schoolforge UK community with the aim of
5591 encouraging UK schools to adopt free/open source software. Five or six
5592 years ago we had about
50 schools interested in some way, but we
5593 weren
't able to convert many of them into sustainable
5594 installations.
</p
>
5596 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5597 project?
</strong
></p
>
5599 <p
>Skolelinux had two representatives at an early Edubuntu meeting in
5600 London which I attended. However at that time our school network had
5601 just been installed using CentOS, LTSP
4 and GNOME. When LTSP
5 came
5602 along we switched to Edubuntu thin client servers so now we have a
5603 mixed environment which includes Windows PCs and student laptops, as
5604 well as their MacBooks and iPads. However, the proprietary systems
5605 have always been rather problematic, and we never built a GUI for the
5606 LDAP server, so when I discovered Skolelinux is configured for all
5607 these things we decided to try it.
</p
>
5609 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5610 Edu?
</strong
></p
>
5612 <p
>By far the biggest advantage is the Debian Edu community. Apart
5613 from that I have always believed in the same
"sustainable computing
"
5614 goals that Skolelinux is built on: installing Linux on computers which
5615 would otherwise be thrown away, to provide a reliable, secure and
5616 low-cost IT environment for schools. From my own experience I know
5617 that a part-time person can teach and manage a network of about
25
5618 Linux computers, but it would take much more of my time if we had
5619 proprietary software everywhere.

><strong
>What do you see as the disadvantages of Skolelinux/Debian
5622 Edu?
</strong

5624 <p
>As a newcomer I
'm just finding out who
's who in the community and
5625 how you
're organised, and what your procedures are for dealing with
5626 various things such as editing manual pages and so-on. The only
5627 English language mailing list seems to be for developers as well as
5628 users, so my inbox needs heavy pruning each day!
</p

5630 <p
><strong
>Which free software do you use daily?
</strong
></p
>
5632 <p
>Besides the software already mentioned at school we use Samba,
5633 OpenLDAP, CUPS, Nagios and Dansguardian for the network, and on the
5634 desktops we have LibreOffice, Firefox, GIMP and Inkscape. At home I
5635 use Ubuntu and an Android
4 eePad Transformer (but I
'm not sure if
5636 that counts...)
</p
>
5638 <p
><strong
>Which strategy do you believe is the right one to use to
5639 get schools to use free software?
</strong
></p
>
5641 <p
>That
's a tough question! For very many years UK schools installed
5642 and taught only proprietary software, so that at the highest levels
5643 the notion of
"computer
" means simply
"proprietary office
5644 applications
". However, schools today are experiencing budget
5645 constraints, and many are having to think hard about upgrading Windows
5646 XP. At the same time, we have students showing teachers how to use
5647 iPads, MacBooks and Android, so the choice of operating system is no
5648 longer quite so automatic. What is more, our government at last
5649 realised that we need people with programming skills, so they
're
5650 putting coding back in the curriculum! And it
's encouraging that the
5651 first
10,
000 Raspberry Pi units sold out in
2 hours.
</p
>
5653 <p
>I don
't really know what strategy is going to get UK schools to use
5654 free software, but building an active community of Skolelinux/Debian
5655 Edu users in this country has to be part of it.

>Documentation in Debian Edu is provided in several languages, and
5665 it is important to make it both easy to contribute and to keep the
5666 translated versions in sync. To do this we have come up with what we
5667 believe is a very efficient work flow.
</p
>
5671 <li
>The documentation is written in a
5672 <a href=
"http://moinmo.in
">moinmoin wiki
</a
> (see for example
5673 <a href=
"http://wiki.debian.org/DebianEdu/Documentation/Squeeze
">the
5674 Squeeze release manual
</a
>) with support for exporting the content as
5675 docbook XML.
</li
>
5677 <li
>This docbook document is given to po4a to extract a gettext style
5678 .pot file with the content, which in turn is used to create .po files
5679 with the translated text.
</li
>
5681 <li
>The .po files are given to translators, and they can always tell
5682 which part of the original wiki document is new or changed. They can
5683 use their normal translation tools like lokalize or poedit to write
5684 the translation. There is even a system in place to handle translated
5687 <li
>The translated .po files are combined with the original docbook
5688 XML document using po4a to create a translated docbook document.
</li
>
5690 <li
>The final step is to use all the generated docbook files and
5691 create PDF and HTML version of the original and translated documents.
</li
>
5695 <p
>This setup work very well, but have a few issues. The biggest
5696 issue is that
<a href=
"http://moinmo.in/DocBook
">the docbook support
5697 we use in moinmoin
</a
> is not actively maintained. The docbook
5698 support is also buggy, and our build system contain workarounds to
5699 make sure the generated docbook is usable despite these bugs.
</p

5758 <p
>Jeg hørte om det først når jeg jobbet i Redpill Linpro. Men jeg
5759 har også en datter som går på en friskole, som også bruker Skolelinux.
5760 Som kjent har ikke friskoler de samme økonomiske rammebetingelsene som
5761 offentlige skoler, så for dem var det det absolutt beste alternativet.
5762 De anser også Skolelinux som et stabilt system, som bare går og går (i
5763 motsetning til det lille Windows-baserte nettverket de har på
5764 admin-siden).

5768 <p
>Sentralisert drift av tynne og diskløse arbeidsstasjoner. Således
5769 lydløse og raskere arbeidsstasjoner som er bedre i klasserommet.
5770 Lengre levetid på PC
'er. Store besparelser på maskinvare og drift. Og
5771 så klart fjerning av alle lisenskostnader. Personlig synes jeg også at
5772 mange av programmene er bedre enn alternativene. Men dette er ofte en
5773 smakssak og avhengig om man må ha det man er vant til fra før.

5775 <p

>Hva er ulempene med Skolelinux slik du ser det?

5777 <p
>For lite kjentskap til løsningen. Noen ganger for dårlig
5778 kompatibilitet med arbeidsstasjoners/bærbare maskiner sine
5779 nettverksdrivere eller skjermkort. Men dette løser vi i skolene ved
5780 standardisering. Ellers er det få, om nesten ingen, av de kjente
5781 maskinvare / infrastruktur leverandørene til fylkes- / kommuner som
5782 tilbyr denne plattformen. Skal dette endre seg så må kommunene selv
5783 sette slike krav til leverandørene.
</p

5785 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
5787 <p
>Har brukt OpenOffice.org siden starten (
2001 ?), Kun Linux på
5788 desktop siden
2005. Bruker i dag Kubuntu, Libreoffice og ymse annet
5789 programvare til ulik kontorbruk som er lett å installere / teste via
5790 alle programarkivene som finnes.

5792 <p

>Hvilken strategi tror du er den rette å bruke for å få
5793 skoler til å ta i bruk fri programvare?
</strong
></p
>
5795 <p
>Fortsette å presentere flere av de gode eksemplene hvor Debian Edu
5796 / Skolelinux brukes i kommuner og enkeltskoler. Vi må få bedre frem
5797 at det er mulig tilknytte både Windows og Mac klienter på denne
5798 plattformen (selv om det vil øke driftskostnadene). Dette gjøres
5799 mange steder. Spesielt er det mange lærere som ønsker å bruke
5800 Windows/Mac-bærbare, gjerne som sin private PC også. Det er også mulig
5801 for kommunen å integrere med Active Directory i stedet for OpenLDAP
5802 som kommer med ut av boksen (selv om også dette øker kostnadene).
5803 Dette vil muligens bidra til å fjerne noe motstand hos noen
5804 potensielle brukere / driftpersonell for å ta i bruk noe
5805 nytt. Fremveksten av mobile brukere og nettbrett går i vår favør.
5806 Brukerne blir kjent og vant til flere nye operativsystemer /
5807 brukergrensesnitt. Så utviklerfellesskapet bør jobbe videre med å
5808 integrere flere nye klienttyper, som ultra lav-kostklienter og
5809 nettbrett (blant annet fri programvare-alternativet

>Inspired by
<a href=
"http://raphaelhertzog.com/tag/interview/
">the
5841 interview series
</a
> conducted by Raphael, I started a Norwegian
5842 interview series with people involved in the Debian Edu / Skolelinux
5843 community. This was so popular that I believe it is time to move to a
5844 more international audience.
</p
>
5846 <p
>While
<a href=
"http://www.skolelinux.org/
">Debian Edu and
5847 Skolelinux
</a
> originated in France and Norway, and have most users in
5848 Europe, there are users all around the globe. One of those far away
5849 from me is Nigel Barker, a long time Debian Edu system administrator
5850 and contributor. It is thanks to him that Debian Edu is adjusted to
5851 work out of the box in Japan. I got him to answer a few questions,
5852 and am happy to share the response with you. :)
5855 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
5857 <p
>My name is Nigel Barker, and I am British. I am married to Yumiko,
5858 and we have three lovely children, aged
15,
14 and
4(!) I am the IT
5859 Coordinator at Hiroshima International School, Japan. I am also a
5860 teacher, and in fact I spend most of my day teaching Mathematics,
5861 Science, IT, and Chemistry. I was originally a Chemistry teacher, but
5862 I have always had an interest in computers. Another teacher teaches
5863 primary school IT, but apart from that I am the only computer person,
5864 so that means I am the network manager, technician and webmaster,
5865 also, and I help people with their computer problems. I teach python
5866 to beginners in an after-school club. I am way too busy, so I really
5867 appreciate the simplicity of Skolelinux.
</p
>
5869 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5870 project?
</strong
></p
>
5872 <p
>In around
2004 or
5 I discovered the ltsp project, and set up a
5873 server in the IT lab. I wanted some way to connect it to our central
5874 samba server, which I was also quite poor at configuring. I discovered
5875 Edubuntu when it came out, but it didn
't really improve my setup. I
5876 did various desperate searches for things like
"school Linux server
"
5877 and ended up in a document called
"Drift
" something or other. Reading
5878 there it became clear that Skolelinux was going to solve all my
5879 problems in one go. I was very excited, but apprehensive, because my
5880 previous attempts to install Debian had ended in failure (I used
5881 Mandrake for everything - ltsp, samba, apache, mail, ns...). I
5882 downloaded a beta version, had some problems, so subscribed to the
5883 Debian Edu list for help. I have remained subscribed ever since, and
5884 my school has run a Skolelinux network since Sarge.

5887 Edu?
</strong

5889 <p
>For me the integrated setup. This is not just the server, or the
5890 workstation, or the ltsp. Its all of them, and its all configured
5891 ready to go. I read somewhere in the early documentation that it is
5892 designed to be setup and managed by the Maths or Science teacher, who
5893 doesn
't necessarily know much about computers, in a small Norwegian
5894 school. That describes me perfectly if you replace Norway with

5900 <p
>The desktop is fairly plain. If you compare it with Edubuntu, who
5901 have fun themes for children, or with distributions such as Mint, who
5902 make the desktop beautiful. They create a good impression on people
5903 who don
't need to understand how to use any of it, but who might be
5904 important to the school. School administrators or directors, for
5905 instance, or parents. Even kids. Debian itself usually has ugly
5906 default theme settings. It was my dream a few years back that some
5907 kind of integration would allow Edubuntu to do the desktop stuff and
5908 Debian Edu the servers, but now I realise how impossible that is. A
5909 second disadvantage is that if something goes wrong, or you need to
5910 customise something, then suddenly the level of expertise required
5911 multiplies. For example, backup wasn
't working properly in Lenny. It
5912 took me ages to learn how to set up my own server to do rsync backups.
5913 I am afraid of anything to do with ldap, but perhaps Gosa will

>Which free software do you use daily?
</strong
></p
>
5918 <p
>Nowadays I only use Debian on my personal computers. I have one for
5919 studio work (I play guitar and write songs), running AV Linux
5920 (customised Debian) a netbook running Squeeze, and a bigger laptop
5921 still running Skolelinux Lenny workstation. I have a Tjener in my
5922 house, that
's very useful for the family photos and music. At school
5923 the students only use Skolelinux. (Some teachers and the office still
5924 have windows). So that means we only use free software all day every
5925 day. Open office, The GIMP, Firefox/Iceweasel, VLC and Audacity are
5926 installed on every computer in school, irrespective of OS. We also
5927 have Koha on Debian for the library, and Apache, Moodle, b2evolution
5928 and Etomite on Debian for the www. The firewall is Untangle.

><strong
>Which strategy do you believe is the right one to use to
5931 get schools to use free software?
</strong
></p
>
5933 <p
>Current trends are in our favour. Open source is big in industry,
5934 and ordinary people have heard of it. The spread of Android and the
5935 popularity of Apple have helped to weaken the impression that you have
5936 to have Microsoft on everything. People complain to me much less about
5937 file formats and Word than they did
5 years ago. The Edu aspect is
5938 also a selling point. This is all customised for schools. Where is the
5939 Windows-edu, or the Mac-edu? But of course the main attraction is
5940 budget.The trick is to convince people that the quality is not
5941 compromised when you stop paying and use free software instead. That
5942 is one reason why I say the desktop experience is a weakness. People
5943 are not impressed when their USB drive doesn
't work, or their browser
5944 doesn
't play flash, for example.

>Many years ago, the
<a href=
"http://www.skolelinux.org/
">Skolelinux
5991 / Debian Edu project
</a
> initiated a student project to create a tool
5992 for making stop motion movies. The proposal came from a teacher
5993 needing such tool on Skolelinux. The project, called
"stopmotion
",
5994 was manned by two extraordinary students and won a school award and a
5995 national aware with this great project. The project was initiated and
5996 mentored by Herman Robak, and manned by the students Bjørn Erik Nilsen
5997 and Fredrik Berg Kjølstad. They got in touch with people at Aardman
5998 Animation studio and received feedback on how professionals would like
5999 such stopmotion tool to work, and the end result was and is used by
6000 animators around the globe. But as is usual after studying, both got
6001 jobs and went elsewhere, and did not have time to properly tend to the
6002 project, and it has been lingering for a few years now. Until last
6005 <p
>Last year some of the users got together with Herman, and moved the
6006 project to Sourceforge and in effect restarted the project under a new
6008 <a href=
"http://sourceforge.net/projects/linuxstopmotion/
">linuxstopmotion
</a
>.
6009 The name change was done to make it possible to find the project using
6010 Internet search engines (try to search for
'stopmotion
' to see what I
6011 mean). I
've been following
6012 <a href=
"https://lists.sourceforge.net/lists/listinfo/linuxstopmotion-community
">the
6013 mailing list
</a
> and the improvement already in place and planned for
6014 the future is encouraging. If you want to make stop motion movies.

6091 <p
>Knut Yrvin her. Jobber i Nokia med å fremme rammeverket Qt og QML
6092 med tilhørende utviklerverktøy. Rollen er som leder av
6093 friprog-samfunn. I fjor var jeg med å legge om utviklingen av Qt til
6094 åpen forvaltning. På den måten kan alle som bidrar til Qt gjøre det
6095 på like vilkår. Nå er det
6096 <a href=

">over
6097 1000 utviklere
</a
> som bidrar til Qt. Med overgangen til åpen
6098 forvaltning er utviklingen av Qt mer åpen enn Linux-kjernen.
</p
>
6100 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
6102 <p
>Jeg var en av initiativtagerne til Skolelinux i
2001. Skolene slet
6103 med både utstyr og Internett-tilgang. De klarte ikke å møte
6104 forventningene til data i skolen. Driften av PC-ene var uholdbar. Som
6105 regel hadde rektor pekt ut en ivrig lærer til å passe på PC-ene,
6106 gjerne naturfaglæreren. Mange lærere jobbet mye ubetalt overtid for å
6107 vedlikeholde
30-
40 datamaskiner på hver sin skole. Med
300 elever og
6108 lærere som brukere, blir det fort mye mer arbeid enn de
4-
8 timene de
6109 kunne bruke på PC-drift. Skolene hadde kun en femtedel av
6110 IT-budsjettet som ble brukt på PC-ene i rådhuset.
</p
>
6112 <p
>Vi erfarte at skolene hadde mye datautstyr som stod ubrukt. Skolene
6113 manglet penger til Microsoft-lisenser. Selv med solide skolerabatter,
6114 kostet Microsoft-lisensene gjerne like mye som PC-ene i seg selv over
6115 en periode på
5-
6 år.
</p
>
6117 <p
>Viktigheten av språklig mangfold og pedagogiske programmer var også
6118 viktig for oss. Vi oversatte mange skoleaktuelle programmer til
6119 nynorsk, nordsamisk og bokmål. Dette lenge før andre tok denne
6120 oppgaven seriøst. Allerede etter ett år hadde vi etablert et helt
6121 arsenal av skoleaktuelle programmer på nynorsk, bokmål og
6122 nordsamisk. Vi spredde vår ide om språklig mangfold til de andre frie
6123 prosjekter internasjonalt. Resultatene ser vi i mange land. Det er de
6124 frie programmene som kommer på brukernes morsmål. Det er en av flere
6125 gode grunner til at fri programvare som LibreOffice, VLC, KDE og
6126 Firefox konkurrerer ut godseid programvare mange steder i verden.
</p
>
6128 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6130 <p
>Fordelene er at Skolelinux tilbyr over
100 skoleaktuelle programmer
6131 på de norske språkene, uten ett øre i lisenskostnader. Systemet gir
6132 enormt lave driftskostnader med diskløse arbeidsstasjoner og bærbare
6133 med roaming. Skolelinux krever også mindre av maskinvaren.
</p
>
6135 <p
>Man kan fint kjøre systemet med
512 MB RAM på en bærbar PC sammen
6136 med en nettvideo i nettleseren og en presentasjon med
6137 LibreOffice. Konkurrerende system krever fort
2 GB RAM for å få til
6138 noe tilsvarende uten at det går ufattelig tregt. Skal man gjøre noe
6139 nyttig, krever konkurrentene til Linux mye større harddisk. Skoler har
6140 rapportert at de fort har fått
50% flere nye maskiner om de velger
6141 Linux. Dette i tillegg til de årlige besparelsene ved å unngå
6142 lisensbetaling til godseid programvare.
</p
>
6144 <p
>De lave driftskostnadene gjør at delstater i Europa har titusener
6145 av datamaskiner med Skolelinux i skolen. F.eks. er det under ti
6146 personer som drifter
70.000 PC-systemer i skolene i Extremadura i
6147 Spania. Det er slett ikke uvanlig at norske kommuner har
1500-
2000
6148 datamaskiner med Skolelinux. Driften tar ett årsverk. Slår flere
6149 kommuner seg sammen, kan de få samme sentraliserte stordriftsfordeler
6150 som delstater i Tyskland og Spania. Delstater som kjører Skolelinux
6151 på alle skolene. Bare noen få personer sentraldrifter titusenvis av
6154 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6156 <p
>Den største ulempen for Skolelinux er motstand mot Linux fra
6157 IT-sjefer i det offentlige. Dette er ledere som holder innlegg som
6158 snytt ut av evangelist-håndboka til Microsoft. Dette gjøres i ett
6159 arbeidsmarked med stor vekst i etterspørselen etter Linux-fagfolk i
6160 privat sektor. Etterspørselen har økt mer enn noe annet tekniske yrke
6161 siste tiåret. Åtte av ti ledere vil ansette Linux-fagfolk i
2012,
6162 rapporterer jobbnettstedet Dice.com på oppdrag av Linux
6163 Foundation.
</p
>
6165 <p
>Det mangler
16.000 ingeniører og IKT-fagfolk i Norge rapporterte
6166 arbeids- og velferdsetaten NAV. Linux-fagfolk kan velge svært
6167 interessante jobber med alt fra apps på ledende mobilsystem laget med
6168 Linux, sky- tjenester eller web-applikasjoner. De raskest voksende
6169 teknologiselskapene i verden er ute etter Linux-fagfolk. Det være seg
6170 Amazon, Google, Facebook og IBM for å nevne noen. Linux er kritisk
6171 for å sikre veksten i markedet. Det sier seg selv at lønningene og
6172 jobbmulighetene er bedre enn for andre tekniske yrker.
</p
>
6174 <p
>Skal man lage apps for mobilen, smart-TV-en eller
6175 underholdningssystemet i bilen eller på flyet, er det Linux som
6176 gjelder. Med en slik konkurranse om Linux-kompetansen, kombinert med
6177 motstanden mot Linux hos mange IT-sjefer i offentlig sektor, så
6178 hindrer kommunene rekruttering av flere Linux- fagfolk. Skolene blir
6179 tvunget til å velge dyrere og mindre komplette IT-system. De har
6180 blitt hengende igjen slik IT var på begynnelsen av
2000- tallet. Dette
6181 fordi IT-ledere ikke har tilpasset seg markedet det siste tiåret.
</p
>
6183 <p
>Når det er sagt, er Skolelinux svært enkelt å lære seg også for de
6184 som ikke kan. Det viser alle lærerne som drifter systemet for
6185 hundrevis og tusenvis av systemer. Det meste er på plass rett ut av
6186 boksen. I tillegg er det solid med dokumentasjon med god hjelp på
6187 nettet. Det er mange kommuner som har ansatt en lærer som først lærte
6188 Skolelinux på sin skole, for så å drifte alle PC-ene i kommunen med
6189 Skolelinux. Det kan fort være snakk om
1000-
3000 datamaskiner på
10-
15
6190 skoler som sentraldriftes med en stilling. Står man ordentlig fast,
6191 kan man også kjøpe profesjonell hjelp fra selskap som støtter
6192 Skolelinux. Det er flere slike selskap i Norge og i utlandet.

6196 <p
>Qt SDK, LibreOffice, Firefox, VLC og KDE-skrivebordet. Dette på et
6197 Debian-basert GNU/Linux-system. Jeg bruker også noen morsomme
6198 3D-spill. Idag kan jeg velge mellom over
30.000 Linux-programmer. Det
6199 finnes ikke tid i livet å undersøke alle valgmulighetene. Derfor er
6200 det bra med Skolelinux i skolen, da utvalget av programmer er
6201 begrenset til hva som er aktuelt i skolefagene.

><strong
>Hvilken strategi tror du er den rette å bruke for å få
6204 skoler til å ta i bruk fri programvare?
</strong
></p

6206 <p
>Vi må selge hele Skolelinux forhåndsinstallert på maskinvare i hele
6207 pakker med
50-
100-
1000 PC-klienter med servere. Dette kan selges til
6208 enkeltskoler eller hele kommuner. Pakken må inneholde tjenermaskiner,
6209 svært rimelige diskløse arbeidsstasjoner, nettbrett med Plasma Active,
6210 og bærbare med roaming. Alt er godt testet med Debian. I et slikt
6211 anbud er det mulig å legge til sentraliserte drifts- og
6212 støttetjenester.
</p
>
6214 <p
>Man bør også selge sky-tjenester som læreadministrative systemet
6215 Moodle og driftsovervåking. I tillegg så bør man slenge seg på med
6216 presentasjoner de gangene LibreOffice og andre friprog-produkter
6217 selges til kommuner.

6257 norske utgaven av OpenOffice.org. Arbeidet har hele tiden vært

>New in the Squeeze version of
6310 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> is the
6311 ability for clients to automatically configure their proxy settings
6312 based on their environment. We want all systems on the client to use
6313 the WPAD based proxy definition fetched from
<tt
>http://wpad/wpad.dat
</tt
>, to
6314 allow sites to control the proxy setting from a central place and make
6315 sure clients do not have hard coded proxy settings. The schools can
6316 change the global proxy setting by editing
6317 <tt
>tjener:/etc/debian-edu/www/wpad.dat
</tt
> and the change propagate
6318 to all Debian Edu clients in the network.
</p
>
6320 <p
>The problem is that some systems do not understand the WPAD system.
6321 In other words, how do one get from a WPAD file like this (this is a
6322 simple one, they can run arbitrary code):
</p
>
6324 <blockquote
><pre
>
6325 function FindProxyForURL(url, host)
6327 if (!isResolvable(host) ||
6328 isPlainHostName(host) ||
6329 dnsDomainIs(host,
".intern
"))
6330 return
"DIRECT
";
6332 return
"PROXY webcache:
3128; DIRECT
";
6334 </pre
></blockquote
>
6336 <p
>to a proxy setting in the process environment looking like this:
</p
>
6338 <blockquote
><pre
>
6339 http_proxy=http://webcache:
3128/
6340 ftp_proxy=http://webcache:
3128/
6341 </pre
></blockquote
>
6343 <p
>To do this conversion I developed a perl script that will execute
6344 the javascript fragment in the WPAD file and return the proxy that
6346 <tt
><a href=
"http://www.debian.org/
">http://www.debian.org/
</a
></tt
>,
6347 and insert this extracted proxy URL in
<tt
>/etc/environment
</tt
> and
6348 <tt
>/etc/apt/apt.conf
</tt
>. The perl script wpad-extract work just
6349 fine in Squeeze, but in Wheezy the library it need to run the
6350 javascript code is
<a href=
"http://bugs.debian.org/
631045">no longer
6351 able to build
</a
> because the C library it depended on is now a C++
6352 library. I hope someone find a solution to that problem before Wheezy
6353 is frozen. An alternative would be for us to rewrite wpad-extract to
6354 use some other javascript library currently working in Wheezy, but no
6355 known alternative is known at the moment.
</p
>
6357 <p
>This automatic proxy system allow the roaming workstation (aka
6358 laptop) setup in Debian Edu/Squeeze to use the proxy when the laptop
6359 is connected to the backbone network in a Debian Edu setup, and to
6360 automatically use any proxy present and announced using the WPAD
6361 feature when it is connected to other networks. And if no proxy is
6362 announced, direct connections will be used instead.
</p
>
6364 <p
>Silently using a proxy announced on the network might be a privacy
6365 or security problem. But those controlling DHCP and DNS on a network
6366 could just as easily set up a transparent proxy, and force all HTTP
6367 and FTP connections to use a proxy anyway, so I consider that
6368 distinction to be academic. If you are afraid of using the wrong
6369 proxy, you should avoid connecting to the network in question in the
6370 first place. In Debian Edu, the proxy setup is updated using dhcp and
6371 ifupdown hooks, to make sure the configuration is updated every time
6372 the network setup changes.
</p
>
6374 <p
>The WPAD system is documented in a
6375 <a href=

01">IETF

6398 <p
>Tror jeg så en annonsering på nettet i slutten av
2001 og ville
6399 være med som oversetter. Jeg kom med på en utviklersamling og
6400 prosjektet var da helt i starten. Det var spennende å være med mens
6401 prosjektet vokste til og utviklet seg.
</p
>
6403 <p
>Jeg har «alltid» vært språkinteressert og hadde nettopp startet med
6404 Linux og tror jeg tenkte det passet å bidra. Var også glad for å få
6405 en Debian-distribusjon, og ville gjerne bruke den selv. Til å begynne
6406 med brukte jeg først Mandrake og så Debian. Og siden jeg oppdaget at
6407 det ikke var noen mulighet for å bruke den som enkeltstående i lang
6408 tid, så gikk jeg etterhvert over til Kubuntu
</p

6410 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6412 <p
>Løsningen er forholdsvis lett å sette opp, gratis, fri programvare
6413 og gjør det mulig å gjenbruke eldre maskiner. Det fine med Debian er
6414 at det er stabilt og har en veldig stor mengde programmer. Jeg liker
6415 også apt. :-) Jeg liker også friheten ved Linux og muligheten til å
6416 delta og forme sin egen datahverdag.

6418 <p

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

6420 <p
>Skolelinux er for lite kjent og for sent ute med å gi ut nye
6421 versjoner.
</p
>
6423 <p
>Da jeg selv i hovedsak bruker Kubuntu, så kan jeg egentlig ikke
6424 svare så detaljert rundt ulempene med Skolelinux. Hovedårsaken til at
6425 jeg bruker Kubuntu er nok at da vi begynte med det mener jeg det ikke
6426 var noen annen løsning. «Vandrende arbeidsstasjon» mener jeg ikke
6427 fantes da. Dessuten ville jeg ha siste versjon, da den KDE-versjonen
6428 som var i Skolelinux den gangen var en god del enklere (tror det var
6429 KDE
2) var dårligere i mine øyne enn versjon
3.

6433 <p

>Hvilken strategi tror du er den rette å bruke for å få
6445 skoler til å ta i bruk fri programvare?
</strong

6447 <p
>Det viktigste er å forankre beslutningen i kollegiet og med de som
6448 er ansvarlige for å vedlikeholde og bruke datamaskinene. Flest mulig
6449 bør være med på å holde det (sosialt) vedlike, kjenne og støtte
6450 prinsippene. Som enkeltmannsprosjekt blir det lett veldig sårbart,
6451 særlig når (Skole)linux ennå i stor grad er en motkultur og ikke noe
6452 en stor nok andel av beslutningstakere, brukere osv kjenner til og
6455 <p
>Jeg tror det viktigste er å fortsette å holde fri programvare godt,
6456 oppdatert, minimere antall feil, ha en god kontakt med brukerne og
6457 attraktivt og spennende programmer. Beholde alt som er bra og ha det
6458 tilgjengelig samtidig som man tilbyr det nyeste og rareste for de som
6459 vil ha det.

>Since the Lenny version of
6469 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>, a
6470 feature to save power have been included. It is as simple as it is
6471 practical: Shut down unused clients at night, and turn them on again
6472 in the morning. This is done using the
6473 <a href=
"http://packages.qa.debian.org/s/shutdown-at-night.html
">shutdown-at-night
</a
> Debian package.
</p
>
6475 <p
>To enable this feature on a client, the machine need to be added to
6476 the netgroup shutdown-at-night-hosts. For Debian Edu, this is done in
6477 LDAP, and once this is in place, the machine in question will check
6478 every hour from
16:
00 until
06:
00 to see if the machine is unused, and
6479 shut it down if it is. If the hardware in question is supported by
6481 <a href=
"http://packages.qa.debian.org/n/nvram-wakeup.html
">nvram-wakeup
</a
>
6482 package, the BIOS is told to turn the machine back on around
07:
00 +-
6483 10 minutes. If this isn
't working, one can configure wake-on-lan to
6484 try to turn on the client. The wake-on-lan option is only documented
6485 and not enabled by default in Debian Edu.
</p
>
6487 <p
>It is important to not turn all machines on at once, as this can
6488 blow a fuse if several computers are connected to the same fuse like
6489 the common setup for a classroom. The nvram-wakeup method only work
6490 for machines with a functioning hardware/BIOS clock. I
've seen old
6491 machines where the BIOS battery were dead and the hardware clock were
6492 starting from
0 (or was it
1990?) every boot. If you have one of
6493 those, you have to turn on the computer manually.
</p
>
6495 <p
>The shutdown-at-night package is completely self contained, and can
6496 also be used outside the Debian Edu environment. For those without a
6497 central LDAP server with netgroups, one can instead touch the file
6498 <tt
>/etc/shutdown-at-night/shutdown-at-night
</tt
> to enable it.
6499 Perhaps you too can use it to save some power?

</p

6523 <li
>It is now possible to change the pre-configured IP subnet from
6524 10.0.0.0/
8 to something else by using the subnet-change tool after
6525 the installation.
</li

6527 <li
>Too full partitions are now automatically extended on the Main
6528 Server, based on the rules specified in /etc/fsautoresizetab.
</li
>
6530 <li
>The CUPS queues are now automatically flushed every night, and all
6531 disabled queues are restarted every hour. This should cut down on
6532 the amount of manual administration needed for printers.
</li
>
6534 <li
>The set of initial users have been changed. Now a personal user
6535 for the local system administrator is created during installation
6536 instead of the previously created localadmin and super-admin users,
6537 and this user is granted administrative privileges using group
6538 membership. This reduces the number of passwords one need to keep
6539 up to date on the system.
</li
>
6543 <p
>The new main server seem to work so well that I am testing it as my
6544 private DNS/LDAP/Kerberos/PXE/LTSP server at home. I will use it look
6545 for issues we could fix to polish Debian Edu even further before the
6546 final Squeeze release is published.

>With some computer hardware, one need non-free firmware blobs.
6562 This is the sad fact of todays computers. In the next version of
6563 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> based
6564 on Squeeze, we provide several scripts and modifications to make
6565 firmware blobs easier to handle. The common use case I run into is a
6566 laptop with a wireless network card requiring non-free firmware to
6567 work, but there are other use cases as well.
</p
>
6569 <p
>First and foremost, Debian Edu provide ISO images for DVD and CD
6570 with all firmware packages in the Debian sections main and non-free
6571 included, to ensure debian-installer find and can install all of them
6572 during installation. This take care firmware for network devices used
6573 by the installer when installing from from local media. But for
6574 example multimedia devices are not activated in the installer and are
6575 not taken care of by this.
</p
>
6577 <p
>For non-network devices, we provide the script
6578 <tt
>/usr/share/debian-edu-config/tools/auto-addfirmware
</tt
> which
6579 search through the
<tt
>dmesg
</tt
> output for drivers requesting extra
6580 firmware. The firmware file name is looked up in the Contents-ARCH.gz
6581 file available in the package repository, and the packages providing
6582 the requested firmware file(s) is installed. I have proposed to do
6583 something similar in debian-installer (BTS report
6584 <a href=
"http://bugs.debian.org/
655507">#
655507</a
>), to allow PXE
6585 installs of Debian to handle firmware installation better. Run the
6586 script as root from the command line to fetch and install the needed
6587 firmware packages.
</p
>
6589 <p
>Debian Edu provide PXE installation of Debian out of the box, and
6590 because some machines need firmware to get their network cards
6591 working, the installation initrd some times need extra firmware
6592 included to be able to install at all. To fill the PXE installation
6593 initrd with extra firmware, the
6594 <tt
>/usr/share/debian-edu-config/tools/pxe-addfirmware
</tt
> script is
6595 provided. Again, just run it as root on the command line to fill the
6596 PXE initrd with firmware packages.
</p
>
6598 <p
>Last, some LTSP clients might also need firmware to get their
6599 network cards working. For this,
6600 <tt
>/usr/share/debian-edu-config/tools/ltsp-addfirmware
</tt
> is
6601 provided to update the LTSP initrd with firmware blobs. It is used
6602 the same way as the other firmware related tools.
</p
>
6604 <p
>At the moment, we do not run any of these during installation. We
6605 do not know if this is acceptable for the local administrator to use
6606 non-free software, and it is their choice.

6664 <description><p
>The next version of
<a href=
"http://www.skolelinux.org/
">Debian Edu
6665 / Skolelinux
</a
> will include a new tool
6666 <tt
>sitesummary2ldapdhcp
</tt
>, which can be used to quickly set up all
6667 the computers in a school without much manual labour. Here is a short
6668 summary on how to use it to set up a new school.
</p
>
6670 <p
>First, install a combined Main Server and Thin Client Server as the
6671 central server in the network. Next, PXE boot all the client machines
6672 as thin clients and wait
5 minutes after the last client booted to
6673 allow the clients to report their existence to the central server. When
6674 this is done, log on to the central server and run
6675 <tt
>sitesummary2ldapdhcp -a
</tt
> in the
<tt
>konsole
</tt
> to use the
6676 collected information to generate system objects in LDAP. The output
6677 will look similar to this:
</p
>
6679 <p
><blockquote
><pre
>

6687 enter password: *******
6689 </pre
></blockquote
></p
>
6691 <p
>After providing the LDAP administrative password (the same as the
6692 root password set during installation), the LDAP database will be
6693 populated with system objects for each PXE booted machine with
6694 automatically generated names. The final step to set up the school is
6695 then to log into
<a href=
"https://oss.gonicus.de/labs/gosa/
">GOsa
</a
>,
6696 the web based user, group and system administration system to change
6697 system names, add systems to the correct host groups and finally
6698 enable DHCP and DNS for the systems. All clients that should be used
6699 as diskless workstations should be added to the workstation-hosts
6700 group. After this is done, all computers can be booted again via PXE
6701 and get their assigned names and group based configuration
6702 automatically.
</p
>
6704 <p
>We plan to release beta3 with the updated version of this feature
6705 enabled this weekend. You might want to give it a try.
</p
>
6707 <p
>Update
2012-
01-
28: When calling sitesummary2ldapdhcp to add new
6708 hosts, one need to add the option -a. I forgot to mention this in my
6709 original text, and have added it to the text now.

6718 <description><p
>I serien med intervjuer av folk i
6719 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet, har jeg nå
6720 lyktes med å få tak i en skolemann som ikke er aktiv med utviklingen,
6721 men likevel har vært med nesten siden starten av prosjektet. Jeg
6722 ønsker derfor velkommen til Paul Reidar Løsnesløkken, en mann med
6723 mange års erfaring i bruk av Skolelinux.
</p
>
6725 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
6727 <p
>Jeg driftet tidligere IKT løsningen for skolene i
6728 <a href=
"http://www.nord-odal.kommune.no/
">Nord-Odal
</a
>. I dag er jeg
6729 IKT-konsulent for hele kommunen og samarbeider med
6730 <a href=
"http://www.hedmarken-ikt.no/
">Hedmark-IKT
</a
> for best mulig
6731 tjenester til kommunen. Jeg har bakgrunn som elektronikkreparatør og
6732 grunnskolelærer og har tatt en del fag innen IKT, i hovedsak
6733 driftsfag. IKT i Nord-Odal kommune blir i dag driftet av Hedmark IKT
6734 som er et samarbeid mellom Løten, Stange, Grue, Hamar, Kongsvinger og
6735 Nord-Odal. Jeg er fortsatt
"IKT-personen
" på skolene i kommunen og
6736 følger opp og gjør enkelte mindre endringer der.
</p
>
6738 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
6740 <p
>Kommunen satset på Skolelinux i
2004. Jeg var ikke med i
6741 beslutningsprosessen den gang, men ble likevel med fra starten når
6742 dette ble levert.
</p
>
6744 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6746 <p
>Fordelene med Skolelinux er rask oppstart, sentral drift av
6747 klientene, klienter som jobber raskt og effektivt, bedre
6748 funksjonalitet på eldre utstyr og en ganske god programpakke med fri
6749 programvare som følger med. Løsningen med halvtykke klienter gjør at
6750 prosessering skjer lokalt med alltid ferske maskiner.
</p
>
6752 <p
>Skolelinux kan fungere godt på gammelt utstyr, men det er klart at
6753 utstyr også blir for gammelt selv for Skolelinux. I forbindelese med
6754 at vi nylig fikk nye servere og ny installasjon kastet jeg ut ca
60
6755 klienter som fortsatt var i drift etter at de var kjøpt godt brukt i
6756 2004. Noe var rundt
15 år gammelt, men var fortsatt i bruk. Noen
6757 klaget på at det nå gikk veldig tregt på en del pedagogiske nettsider
6758 med flash o.l. Det er fullt forståelig.
</p
>
6760 <p
>Jeg fikk nylig et spørsmål fra ungdomsskolens rektor om jeg kunne
6761 legge inn
<a href=
"http://freemind.sourceforge.net/
">FreeMind
</a
>, et
6762 tankekartprogram , på skolens elev-Windowsmaskiner. Lærerne hadde
6763 vært på kurs og ville ta dette i bruk. Skolen har ca halvparten av
6764 elevmaskinene på bærbare Windowsmaskiner. Da kunne jeg fortelle at
6765 dette programmet allerede lå inne på den nye Skolelinuxløsningen
6766 som nettopp var satt i drift, klart til bruk.
</p
>
6768 <p
>Vi har de bærbare maskinene på ungdomsskolen i domene med
6769 Skolelinux. Dette fungerer også meget bra nå. Elevene får opp en
6770 midlertidig windowsprofil når de logger på. Denne profilen slettes
6771 etter at de logger av, noe som medfører rene profiler hver gang de
6772 starter opp en maskin. De må lagre i sin Skolelinprofil, noe som
6773 medfører at de får tak i sine filer uavhengig av om de starter en
6774 Windowsmaskin eller en Skolelinuxklient. Det er mye mindre trafikk i
6775 det trådløse nettet etter at ikke hele profiler blir lastet opp til de
6776 enkelte Windowsmaskinene og tilbake når man avslutter. Jeg vet ikke om
6777 dette er standardoppsett i Skolelinux, men slik er vårt oppsett
6780 <p
>Vi har i flere år satt opp vår løsning slik at skriverkøer slettes
6781 og skrivere startes hver natt. Hyggelig å høre at dette nå skal bli
6782 en standard i Skolelinuxløsningen. Dette har vært en god hjelp for
6785 <p
>Elevene er lite opptatt av om de jobber på en Skolelinux eller en
6786 Windowsmaskin bare de har de programmene de trenger og at det virker
6787 når det skal brukes. Vi kjører mest mulig de samme programmene på
6788 Windows som i Skolelinux, som f.eks Audacity og LibreOffice.
</p
>
6790 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6792 <p
>Lærere bruker hos oss Windows. Dette fordi de da selv har mer
6793 kontroll over sin maskin, kan bruke den overalt, og kan legge inn
6794 programmer selv når de trenger noe i forhold til kurs o.l de er
6795 på. Jeg tror lærernes selvstendighet her gjør dem tryggere på IKT-bruk
6796 generelt. Det at de av og til får opp advarsler og lignende gjør også
6797 at de må tenke igjennom og spørre om ting rundt datasikkerhet.
</p
>
6799 <p
>Det er en del programmer vi bruker som ikke finnes for Linux. Mest
6800 brukt er nok Photostory3 som brukes i mange sammenhenger, særlig på
6801 ungdomsskolen, bl.a. til å lage herbarier (plantesamling) . Dette
6802 finnes gratis for Windows, men er ikke fri programvare. Vi er opptatt
6803 av at programmer elevene bruker på skolen også kan brukes gratis
6804 hjemme. Det er også en del programmer som brukes til spesielle elever
6805 som bare går i Windows. Det er viktig med fokus på funksjoner og ikke
6806 på hvilket OS man bruker.
</p
>
6808 <p
>For oss er det kombinasjonen mellom Skolelinux og Windows som gir
6809 oss en god og hel løsning. Skolelinux er best der de er gode.
</p
>
6811 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
6813 <p
>Selv er det LibreOffice jeg bruker til daglig. Jeg bruker selv en
6814 Windowsmaskin. Jeg har benyttet en del fri programvare i forbindelse
6815 med sjekking av trafikk i nettverk, slik som Wireshark, men dette er
6816 jo ikke aktuelt for skolene. Jeg er generelt glad i programmer som
6817 fungerer på både Linux og Windows og gjerne MAC.
</p
>
6819 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
6820 skoler til å ta i bruk fri programvare?
</strong
></p
>
6822 <p
>Det er viktig at det benyttes programmer som elevene også kan ta i
6823 bruk hjemme. Det skal da være enkelt, lovlig og gratis for
6824 elevene. Da er jeg ikke lenger veldig opptatt av om det kalles
"fri
6825 programvare
". For skolene tror jeg
"gratis
" og
"funksjonelt
" er bedre
6826 begreper enn
"fri
" i forhold til programmer. De fleste skiller nok
6827 ikke mellom
"fri
" og
"gratis
". Det er nå svært mange elever som
6828 benytter OpenOffice eller LibreOffice som sin primære kontorpakke

>During christmas, I have been working getting the next version of
6885 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> ready
6886 for release. The initial problem I looked at was particularly
6887 interesting.
</p
>
6889 <P
>The installer would hang at the end when it was doing it
6890 post-installation configuration, and whatevery I did to try to find
6891 the cause and fix it always worked while I tested it, but never when I
6892 integrated it into the installer and ran the installation from
6893 scratch. I would try to restart processes, close file descriptors,
6894 remove or create files, and the installer would always unblock and
6895 wrap up its tasks.
</p
>
6897 <p
>Eventually the cause was found. The kernel was simply running out
6898 of entropy, causing the Kerberos setup to hang waiting for more.
6899 Pressing keys was adding entropy to the kernel, and thus all my tries
6900 to fix the problem worked not because what I was typing to fix it, but
6901 because I was typing.
</P
>
6903 <p
>The fix I implemented was to add a background process looking at
6904 the level of entropy in the kernel (by checking
6905 /proc/sys/kernel/random/entropy_avail), and if it was too small, the
6906 installer will flush the kernel file buffers and do
'find /
' to
6907 generate some disk IO. Disk IO generate entropy in the kernel, and is
6908 one of the few things that can be initated from within the system to
6909 generate entropy.
</p
>
6911 <p
>The fix is in
6912 <a href=

">beta1
6913 of the Debian Edu/Squeeze

>Etter en lang pause er det klart for neste mann ut i min serie med
6926 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-relaterte personer.
6928 Denne gangen har jeg besøk av et avtroppende styremedlem i
6929 <a href=
"http://www.friprogramvareiskolen.no/
">FRISK
</a
>, og en mann
6930 som har vært aktiv i Linux-miljøet i Bergen siden
90-tallet.
</p

6932 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
6934 <p
>Jeg heter Peter Hansteen, og jobber til daglig som seniorkonsulent
6935 i EDB ErgoGroup i Bergen. I praksis betyr det systemadministrasjon på
6936 Unix (primært Solaris, men en viss komponent av Linux). Men Solaris
6937 er for meg et relativt nytt bekjentskap, hovedplattformen min har
6938 generelt vært OpenBSD og til dels FreeBSD.
</p

6940 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
6942 <p
>Jeg husker ikke helt alle detaljene mer ;) - men jeg tror det var
6943 gjennom news-gruppen no.it.os.unix.linux.diverse, efn-listen og
6944 etterhvert også BLUG-miljøet her i Bergen. Vi hadde et par
6945 Skolelinux-sentrerte BLUG-møter for noen år siden, og det har vært et
6946 par Skolelinux-utviklersamlinger her.
</p
>
6948 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6950 <p
>Jeg bruker dessverre ikke Skolelinux daglig. Men slik jeg kjenner
6951 prosjektet har det vært i stand til å ta opp i seg det beste av fri
6952 programvare i mange kategorier, så fra et sysadmin-perspektiv ser det
6953 ut som en svært behagelig sak. For brukerne er det vel både en fordel
6954 og en ulempe at det ikke er Windows. Men vi håper at fordelene med et
6955 fritt system etterhvert vil bli åpenbare for både elever, lærekrefter
6956 og foreldre.
</p
>
6958 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6960 <p
>Vel, ulempen er vel først og fremst at andre aktører med mer
6961 kapitalmuskel har klart å etablere seg som det både lærere og foreldre
6962 føler seg trygge på, selv om det etter mitt hode ikke er noen grunn
6963 til å være spesielt trygg på de kommersielle alternativene.
</p
>
6965 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
6967 <p
>Når jeg får bestemme helt selv, bruker jeg kun fri programvare. Da
6968 helst med vekt på ting som kjører greit på OpenBSD. Hjemme er det
6969 OpenBSD, Ubuntu eller FreeBSD vi bruker. På skrivebordet er det en
6970 avveining mellom Gnome, KDE eller hva-det-nå-heter som er
6971 standardvalget i Ubuntu, ellers er det de kjente tingene som
6972 LibreOffice, Emacs, mplayer. På server er det selvfølgelig Apache,
6973 for overvåking både OpenNMS og Nagios (det bare ble sånn, og
6974 forskjellige siter). Jeg skriver til tider om slikt jeg holder på med
6976 <a href=
"http://bsdly.blogspot.com
">http://bsdly.blogspot.com
</a
>.
</p
>
6978 <p
>Men vi må nevne at selv vi har en Microsoft-ting som vi slår på når
6979 vi av en eller annen grunn må. Det betyr igjen vanligvis når en
6980 mobiltelefon eller en annen lukket elektronisk dings krever kontakt
6981 via en slik for å få oppdateringene sine.
</p
>
6983 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
6984 skoler til å ta i bruk fri programvare?
</strong
></p
>
6986 <p
>Hadde vi hatt det rette svaret på det spørsmålet, så hadde vi
6987 gjerne hatt Skolelinux som førstevalg på alle skoler ;)
</p
>
6989 <p
>Men jeg tror vi må legge vekt på flere forskjellige ting. En helt
6990 sentral sak er å fokusere på fri programvare og åpne standarder som de
6991 demokratiske verdiene de faktisk er. Det har kanskje kommet litt for
6992 mye i bakgrunnen i forhold til strevet etter å lage det mest mulig
6993 'brukervennlige
' systemet. Det er en tung vei å gå, så det er
6994 forståelig at freenix-aktivister heller velger å skrive kode og annet
6995 som er mer lystbetont. Mer praktisk tror jeg vi må gjøre i alle fall
6996 to ting: For det første sørge for å fortsette med å levere det best
6997 mulige frie produktet, slik at det er lett å både komme i gang og
6998 holde systemene i daglig drift, og for det andre
2) spore opp mulige
6999 aktivister der de finnes, via lokale brukergrupper, sosiale medier
7000 eller annet og sørge for at de fortsetter å være aktive. Mer og
7001 mindre uformelle treff kan være nyttig i tillegg til de mer
7002 organiserte møtene med foredrag, konferanser og utviklersamlinger.

</p

7017 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
7019 <p
>Mitt navn er Frode Jemtland, og jeg jobber i Hedmark IKT, som er et
7020 driftsselskap for Grue, Hamar, Kongsvinger, Løten, Nord-Odal og Stange
7021 kommuner. Her er jeg leder for avdelingen Løsninger og Arkitektur. Vi
7022 har i hovedansvar for servere, infrastruktur og løsninger som
7025 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
7027 <p
>Jobbet i IBM fra
2000, og da spesielt med Linux. Dette var da et av
7028 de mest tydelige linux prosjektene i Norge, og her ønsket jeg å
7029 bidra. Var aktivt med i prosjektet i
4-
5 år.
</p
>
7031 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7033 <p
>Fordelene slik jeg ser det er den sentraliserte driftmodellen, og
7034 alle de vel gjennomtenkte løsningene som er inkludert i denne
7035 løsningen. Samtidig er det basert på en stabil, og godt kjent
7036 plattform. Dette vil si at man har en løsning som skal være mye
7037 tilgjengelig, og hvor det er relativt enkelt å få tak i personer som
7038 kan mye om den grunnleggende plattformen.
</p
>
7040 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7042 <p
>De største utfordringene med en løsningen er at den er intensiv på f.eks
7043 nettverk. I seg selv ikke et problem for en enkelt skole, men skal løsningen
7044 kjøres i større skala, med sentraliserte servere, så gir dette noen
7045 utfordringer.
</p
>
7047 <p
>Utifra hva jeg har sett på større installasjoner så er det ikke så
7048 enkelt å skjønne, hva som bør gjøres for at den skal skaleres opp, og
7049 da ta godt vare på alle sider av dette, ikke bare mer server å fordele
7050 last/trykk, men hvordan også beholde robustheten og fleksibiliteten i
7051 løsningen.
</p
>
7053 <p
>En annen utfordring er at stadig flere produkter som skal brukes i
7054 skoleløsningen ikke er laget til å kunne brukes i en
7055 skolelinuxløsning. Det blir derfor fort mye skreddersøm i de
7056 forskjellige installasjonene, for å få diverse pedagogiske programmer,
7057 webløsninger, smartboards, m.m. til å fungere. Man er også en for
7058 liten kundebase til at leverandørene ønsker å gjøre noe med
7059 utfordringen. Problemet overlates til oss.
</p
>
7061 <p
>Det er også en kontinuerlig utfordring rundt problemet med å holde
7062 programvare på stabile versjoner, kontra å få ny funksjonalitet. Dette
7063 er jo en konflikt mellom oss som ønsker å drifte en stabil, og
7064 kostnadseffektiv løsning, mot sluttbrukerne som ønsker seg funksjoner
7065 det er vant med fra andre løsninger, eller som de må ha for at et
7066 eller annet nytt produkt skal fungere i løsningen. Dette er en
7067 utfordring også for andre plattformer.
</p
>
7069 <p
>En siste utfordring som ikke har noe med løsningen å gjøre, men med
7070 det omkringliggende miljøet denne skal kjøre i, er at de enhetene som
7071 skal drifte dataløsninger for kommuner og fylkeskommuner begynner å
7072 profesjonaliseres, og er da avhengig av å ha standard løsninger for å
7073 drifte store brukermasser. MS er selvsagt klar over dette, og har jo
7074 nå flere områder de begynner å bli veldig dominerende på. Den største,
7075 og mest problematiske er katalogtjenesten. Man får snart ikke tak i
7076 større løsninger som ikke krever en AD. Når man da har store enheter
7077 som drifter både kommunalt ansatte og skoler, så vil det være et
7078 stordriftargument å standardisere på en katalog tjeneste, og da har
7079 man ikke noe valg. Her er alle slike driftsenheter for små til å få
7080 gjort om på dette. Her burde konkurransemyndighetene kommet på
7081 banen. Men konkurransetilsynet i USA griper sjeldent (og ikke før det
7082 har gått veldig lang tid) inn i monopolsituasjoner så lenge
7083 monopolisten er et amerikansk firma, så da har vel ikke andre
7084 myndigheter så mye de skulle ha sagt....
</p

7086 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
7088 <p
>Privat kjører jeg Debian på alle mine datamaskiner. Det gjør jeg
7089 også på min jobbmaskin. Vi har også
15-
20 linux servere av typene
7090 SuSE, Debian, Redhat, CentOS m.m. Jeg bruker derfor mye fri
7091 programvare. Av enkelt programmer kan sikkert masse nevnes. Hvis vi
7092 skal begrense oss til daglig, så må jeg si: OpenOffice, Firefox,
7093 Kontact, Kopete, Amarok,
7094 <a href=
"http://gramps-project.org/
">Gramps
</a
>, Kate, ssh, bash,
7095 rsync, backuppc m.m.
</p
>
7097 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
7098 skoler til å ta i bruk fri programvare?
</strong
></p
>
7100 <p
>Det er et godt spørsmål, som jeg har lurt på selv.
</p
>
7102 <p
>Argumentene som ofte har vært brukt om at ting koster mindre holder
7103 ikke mål når man ser på hva som faktisk koster penger. Det er de
7104 ansatte som er en kostnadsdriver. Det vil si at hvis man har et system
7105 som den ansatte kan, så vil en kostnad på dette systemet kunne
7106 forsvares ganske mye ved at den ansatte gjør dette raskere og
7107 effektivt. Også uten å måtte eventuelt leie inn folk.
</p
>
7109 <p
>Jeg syns det er viktigere å fokusere på prinsippet med å velge fri
7110 programvare, men det er også et felt hvor man fort møter lite
7111 forståelse blant de ansatte i skolen.
</p
>
7113 <p
>Her må nok strategien fortsette å være at de sentrale myndighetene
7114 må sende tydelige signaler for hva de ønsker at offentlige enheter
7115 skal gjøre. Det var mye positivt på gang ang. dette for et par år
7116 siden. Både med eNorge og eKommune planene, men dette syns jeg har
7117 stoppet opp. En del av dette kan jo kanskje være usikkerheten som
7118 etter hvert har blitt, når man har sett kompleksiteten i de
7119 prosjektene som har blitt igangsatt. Det har også blitt noe usikkerhet
7120 i markedet ref. Sun, Oracle, Novell, Microsoft m.m. Samtidig har jo
7121 også de proprietære programleverandørene sørget for å endre sine
7122 lisenser slik at man uansett ikke slipper unna kostnaden til deres
7123 produkter, selv om man skulle velge alternativer. Da er det økonomiske
7124 argumentet, som jeg nevnte tidligere, spilt ganske godt ut over
7125 sidelinjen.

7148 <p
>Hmm, det er lenge siden, så det er nesten så jeg ikke husker. Jeg
7149 hadde vel hørt om prosjektet i media før en gjeng i Trondheim startet
7150 opp SPIST, Skolelinux-prosjektet i Sør-Trøndelag, hvor vi hjalp noen
7151 skoler i nærområdet med å installere Skolelinux og finne brukt
7152 IT-utstyr til disse. Det var moro å gjøre noe praktisk for å spre
7153 Skolelinux, og å se hvor fort gjort det var å sette opp utrangerte
7154 klientmaskiner og få disse opp som tynnklienter på helt nye datasaler
7155 på skolene, kun med kostnaden til servere.

7157 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?

7159 <p
>Det er et system spesielt skreddersydd for drift av et stort antall
7160 klienter mot servere, og da spesielt i henhold til skolers behov. Det
7161 er enkelt og billig å installere og drifte, og det trenger ikke ny
7162 maskinvare for god ytelse.

7166 <p
>Hardwarestøtten kunne vært bedre og i enda større grad
7167 installerbart rett ut av boksen. Distribusjonen har til tider hatt
7168 litt gammel programvare pga. at den følger Debian sine utgivelser.
7169 Kanskje man skulle vurdert en versjon basert på Ubuntu eller andre
7170 distribusjoner i tillegg?

7176 Chromium, Pidgin, Digikam, OpenOffice, Wireshark, git og irssi.
7177 Telefonen min er en Android, og der bruker jeg programmene K-
9 Mail,
7178 OI Shopping list, Shuffle, ZXing, OI Notepad og ADW Desktop. På jobb
7179 bruker jeg JBoss, Eclipse, uCLinux for Blackfin, RCF-CPP, Qt, Maven,

7185 <p
>En bør fokusere på totalkostnader inkludert driftsbehov,
7186 fleksibilitet, åpenhet og ikke låsing til en leverandør framfor sparte
7187 lisenskostnader, samt programvarens kvalitet og fortrinn, og at den
7188 fritt kan brukes på et ubegrenset antall PC-er, også hjemme hos
7189 elevene. En bør også forbedre den fri programvaren ved testing,
7190 bugrapportering og kodebidrag om man kan, og ikke anbefale programvare
7191 uten at man har forsikret seg at den har tilstrekkelig kvalitet,
7192 ellers kan man lett oppnå det motsatte. Tror en bør selge inn
7193 konseptet til fylkes-/statsnivå, kanskje med bidrag til
7194 utviklingsarbeid fra disse som alle landets skoler kan få glede

>Mine bloggposter om Linux i skolene i Norge førte til at inspektør
7205 og ildsjel på Harestad skole tok kontakt og fortalte at de bruker
7206 Linux på sin skole, og lurte på om de kunne bidra til å gjøre
7207 fordelene kjent. Riktig nok bruker de ikke
7208 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
> på denne skolen,
7209 men jeg synes dette er en god anledning til å gjøre flere fasetter
7210 rundt Linux-økosystemet kjent, og tok et lite intervju.

7214 <p
>Mitt navn er Odin Hetland Nøsen og er en
70-modell. Jeg er bosatt i
7215 Stavanger og jobber nå på
9. året som undervisninginspektør på
7216 Harestad skole i Randaberg kommune (nabokommune til Stavanger).

7220 <p
>I
2002 begynte daværende IKT-ansvarlige og jeg et arbeid på skolen
7221 med å gå over fra Win98 til... noe annet. Vi testet en rekke
7222 forskjellige løsninger, deriblant Skolelinux, men endte opp med
7223 RedHat. Skolelinux var den gang ikke modent for det vi ville ha. Jeg
7224 har siden fulgt jevnlig med på hva skolelinux holder på med, men har
7225 hele tiden vært bedre fornøyd med vår egen
"standardiserte
" løsning på
7226 RedHat/CentOS og Fedora. Vi snuser for tiden på Ubuntu som løsning på
7227 klientsiden.
</p
>
7229 <p
>I dag har vi på skolen vår en større linux-løsning med
400 klienter
7230 som kjører en blanding av LTSP (tynnklient) og DRBL (tykk klient uten
7231 harddisk) med en masse tjenere på serverrommet. Vi drifter hele
7232 sulamitten selv med webtjener, eposttjener, webmail, filtjenere,
7233 virtuelle tjenere osv. Og IT-ansvarlig har en
80% stilling som
7234 IT-ansvarlig - og så er han KoH-lærer i de resterende
20% :-)

7236 <p
>Du kan få en ide om hva vi holder på med om du går inn på
7237 <a href=
"http://www.gnuskole.no/
">http://www.gnuskole.no/
</a
>.
</p
>
7239 <p
>For å ta brodden av frykten for at ildsjeler gjør skolen sårbar om
7240 ildsjelene falle fra, har jeg forsikret kommunen og skolesjefen i
7241 Randaberg om at det finnes godt kommersielle tjenester vi kan benytte
7242 oss av - om det skulle bli nødvendig. Vi er tre stykker i kommunen som
7243 nå har
<strong
>god
</strong
> linux-kompetanse ift. å drifte et større
7244 system. IT-avdelingen i kommunen vil ikke ta på oss med ildtang -
7245 selv om vi nok har større IT-kompetanse mot linux enn det de selv har
7246 mot windows (de kjøper en
<strong
>masse
</strong
> konsulenttjenester
7247 fra ErgoGroup).
</p
>
7249 <p
>I kvantitet er Harestad og Grødem skole tilsammen et større
7250 IT-system enn resten av Randaberg kommune + Kvitsøy og Rennesøy, som
7251 kommunen også har driftsansvar for. Vi har som sagt rundt
800
7252 maskiner, mens kommunen med sitt driftsansvar har ansvar for rundt
500
7253 maskiner. Det er selvfølgelig litt forskjell i hvor kritiske
7254 tjenestene våre er, men det gir allikevel et litt rart bilde når
7255 IT-avdelingen overhode ikke er interessert i å snakke med oss om
7256 hvordan vi gjør ting :-)
</p
>
7258 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7260 <p
>Fra linux-perspektivet (ikke bare Skolelinux) er det en fordel av
7261 systemet er basert på fri programvare - og dermed fritt i ordets mange
7262 betydninger. Det er alt vi trenger: stabilt, relativt enkelt å drifte
7263 (tross alt - et større windowssystem er ikke enkelt å holde live det
7264 heller), rimelig i innkjøp og drift, og sist, men ikke minst, det er
7265 moderne for sluttbruker! Linux, i sine mange varianter,
7266 <strong
>ser
</strong
> nytt ut, fordi det hele tiden blir
7267 oppdatert. Derfor lever systemet opp til hvordan elever forventer at
7268 et moderne GUI skal være (i motsetning til WinXP :-).
</p
>
7270 <p
>Vi var veldig pragmatiske da vi begynte med linux i skolen. Det var
7271 billig, det fungerte og kunne bruke alle de gamle windows-maskinene
7272 som
"nye
" tynne klienter. I dag er vi mer bevisste fri
7273 programvare-tilhengere. Vi har oppdaget hva det er - og vi liker
7276 <p
>En av de
<strong
>store
</strong
> fordelene med fri programvare er at
7277 vi kan installere tjenester vi ønsker å tilby brukerne våre - uten å
7278 måtte tenke på om vi har råd til lisensene (fordi det er ingen). Alt
7279 vi setter i produksjon er ut i fra brukernes behov og vår kapasitet
7280 til å drifte dem. Vi skreddersyr tjenestene etter behovet og dermed
7281 trenger vi ikke ende opp med å kjøpe en pakke der vi egentlig bare var
7282 interessert i en liten del av den.
</p
>
7284 <p
>Bruk av linux frigjør ikke økonomiske midler, fordi midlene til IKT
7285 i skole er for få i utgangspunktet - men vi får så
7286 <strong
>mye
</strong

7357 <p
>Jeg heter Astri Sletteng. Jeg er lærer og IKT veileder ved Håkvik
7358 skole i Narvik kommune. Min bakgrunn når det gjelder IKT: Av formell
7359 utdannelse har jeg lærerutdanning, Master i skoleledelse og IKT for
7360 lærere. Har jobba som IKT veileder siden
2002.
</p
>
7362 <p
>Det viktigste for meg som IKT veileder er å få fundamentert den
7363 5. basisferdigheten, digital kompetanse ved skolen min på en god måte
7364 slik at hele skolesamfunnet tar i bruk IKT i alle fag. Dette arbeidet
7365 gjøres i nært samarbeid med skolens ledelse.
</p
>
7367 <p
>Min viktigste jobb som IKT veileder er å være motivator og pådriver
7368 i IKT arbeidet ved skolen.
</p
>
7370 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
7372 <p
>Jobber i en kommune hvor vi satser på Fri programvare. I
2004 ble
7373 det gjort et politisk vedtak om at vi skulle innføre Skolelinux ved
7374 alle skolene i kommunen. Jeg har dermed en god del erfaring med
7375 Skolelinux, samt annen fri programvare som Open Office, Joomla, Moodle
7378 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p

7380 <p
>Siden vi jobber med åpen kildekode kan vi få programmene og
7381 produktene tilpasset vår bruk. Det er jo heller ikke en ulempe at
7382 skolen kommer bedre ut økonomisk, men først og fremst er det viktig
7383 for oss at vi har digitale systemer som gjør at vi kan følge
7384 læreplanen i alle fag. Det syns jeg at vi kan gjøre gjennom
7385 Skolelinux.
</p
>
7387 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7389 <p
>Skolen er avhengige av å ha folk på IT avdelinga i kommunen som kan
7390 drive support, og være tilgjengelige når vi trenger hjelp. Det er en
7391 ulempe at ikke alle på denne avdelingen nødvendigvis er god på
7394 <p
>Vi har også noen utfordringer når det kommer til spesielle
7395 programmer som enkelte elever er avhengige av ? og som ikke er
7396 plattform uavhengige. Her har vi i Friprog-verden, men også
7397 departement en jobb å gjøre.
</p

7399 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong

7401 <p
>Skolen vår bruker Skolelinux, Open Office, Iceweazel (Mozilla),
7402 VLC, Tux paint, Scribus, FreeMind, GIMP, digiKam, Ksnapshot, GeoGebra,
7403 Moodle (innført på alle klassetrinn + som et administrativt verktøy)
7404 og Joomla som hjemmeside.
<p
>
7406 <p
>Det er de jeg kommer på i farten. I tillegg har vi Smartboard
7407 installert på server, men det regnes vel ikke som fri programvare?

>Hvilken strategi tror du er den rette å bruke for å få
7410 skoler til å ta i bruk fri programvare?
</strong

7412 <p
>Først og fremst trenger skolen oppetider på sine datasystemer. Syns
7413 også at det at vi kan få tilpasset plattform og systemer til vår bruk
7414 er en god strategi å bruke.

7430 <p
>Rubén Romero y Cordero,
81-modell, deltidspappa (
50%) for en jente
7431 på
6 år. Jobber i Oslo som Global Sales Executive hos Varnish Software
7432 og til daglig har jeg kontakt med kunder fra hele verden. Min
7433 forkjærlighet for fri programvare har gjort at jeg har nå flere års
7434 erfaring med salg av slike løsninger (bl.a. fra Redpill Linpro og
7435 Freecode) og mye innsikt og kunnskap om det globale IT-markedet.
7436 Ellers er jeg involvert i flere prosjekter bl.a. er jeg Ubuntu
7437 Community medlem, kontaktpersonen for Ubuntu Norge og driveren av
7438 SpreadUbuntu marketing prosjektet og nå fersk styremedlem i FRISK. Jeg
7439 har brukt GNU/Linux siden
1997.

7441 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
7443 <p
>Som Debian bruker siden slutten av
90-tallet var det uunngåelig å
7444 ikke komme bort i Skolelinux. Dette var vel i slutten av
2001 når jeg
7445 var student ved UiO. Flere år senere fikk jeg lastet og testet Venus
7446 (Skolelinux
1.0) på release dagen.
</p
>
7448 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7450 <p
>Fri programvare bygges sten for sten i det åpne, slik at koden og
7451 prosessen den lages på kan gjennomskues av andre enn de som har laget
7452 det. Det er et vitenskapelig og gjennomsiktig måte å lage programvare
7455 <p
>Skoler i vårt samfunn skal være steder hvor vitenskapelig kunnskap
7456 deles til alle. I dag har vi ikke et vitenskapelig tilnærming til
7457 hvordan programvaren som brukes på skolen lages. Skolelinux bringer
7458 inn at slik tilnærming i skoleverkets klasserom, siden
7459 operativsystemet er en åpent platform som gir skolene muligheten til å
7460 dra nytte av programvare som er laget av tusenvis av mennesker verden
7461 rundt og som gir elevene så vel som lærerne muligheten til å bruke,
7462 dele, forandre og forbedre OSet sitt uten begrensninger. I den
7463 forbindelsen representerer Skolelinux også konkrete resultater utfra
7464 samhandling på tvers av grenser.
</p
>
7466 <p
>Når det gjelder de tekniske fordelene av Skolelinux er jeg sikker
7467 på at andre enn meg har allerede beskrevet disse bedre enn det jeg
7468 kan. Men jeg kan likevel tilføye noe: Skolelinux som sådan er en
7469 community-drevet operativsystemplatform. Som i ethvert
7470 community-prosjekt har alle Skolelinux brukere muligheten til å
7471 påvirke retning av prosjektet og resultatet som gjenspeiles i
7472 programvaren. Dette kommer sjeldent frem og jeg mener at det er noe
7473 som burde fokuseres mer på.
</p
>
7475 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7477 <p
>De største ulempene er:
</p
>
7480 <li
>Mangel på kompetanse
</li
>
7481 <li
>Mangel av administrative verktøy som kunne hjelpe lokale IT
7482 avdelinger å bruke Skolelinux til mer enn bare en tjener for
7483 terminalklienter. Et eksempel: Zentyal sin web-dashboard.
</li
>
7486 <p
>Bedre og mer intuitive administrative verktøy kunne løst deler av
7487 problemet, men det er unektelig at ved bruk av Skolelinux må
7488 IT-personalet vite hva de gjør for å få ting gjort riktig, eller i det
7489 hele tatt. Med andre platformer er kompetansen enklere tilgjengelig og
7490 løsningene kan fungere på en tilfredstillende, om ikke riktig
7493 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
7495 <p
>Har brukt GNU/Linux utelukkende sommitt skrivebord OS siden
2000. I
7496 dag bruker jeg Ubuntu og gjør det meste med friprogramvare verktøyene
7497 som er tilgjengelige der. Med over
20.000 programmer å velge mellom er
7498 dette mer enn nok for de fleste brukerne.

7500 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
7501 skoler til å ta i bruk fri programvare?
</strong

7503 <p
>Opplysning og pragmatikk. Vi prøver å løse problemer med bruk av
7504 programvare. De fleste utfordringene skolene har på IKT-siden kan
7505 løses ved hjelp av friprogramvareverktøy i dag. Det som trenges er
7506 opplysning, kunnskap og kompetanse.

7533 <p

7534 entusiastiske skolelinuxbrukere og skeptiske
"forståsegpåere

</p

7536 <p
>Jeg husker en leverandør av et stort OS for noen år siden mente at
7537 Skolelinux var kun for hackere og nerder og at ingen seriøse skoler
7538 kunne ta dette i bruk. Heldigvis er kunnskapen større nå og
7539 skikkelige
"IT-folk
" søker alltid å utvide sin kunnskap.
7541 <p
><strong

</strong

7543 <p
>Ja det er mange fordeler. Uavhengighet, stabilitet, åpenhet, standarder

7545 elevene skal jobbe.
</p

7547 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong

7549 <p
>Det største hinderet er det vi opplever på andre områder rundt
7550 fri programvare, nemlig kunnskap. For mange er det trygt å velge det vi
7551 alltid har valgt. Fordi leverandørene rundt oss sitter på den kunnskapen og
7552 de vi støtter oss på har den samme. Hvis vi klarer å riste løs litt og
7553 glemme gamle kriger mellom operativsystemer og leverandører, men sette ned
7554 hva som er viktig og velge ut fra det, så hadde man kanskje kommet ut med
7555 litt andre resultat. Jeg tror IT-folk er konservative og velger tradisjonelt
7556 og det er synd.
</p

7558 <p
><strong

7560 <p
>Jeg bruker Ubuntu, Android, Jolicloud, Open Office, Zimbra, Picasa
7561 og Firefox samt en bråte med tjenester som er webbasert. Det eneste
7562 som er betalingslisens for er OSX. Ser at jeg jobber mer og mer i
7563 skyen og setter pris på alt jeg slipper egen klient til. Derfor er
7564 jeg veldig sjarmert av små kjappe operativsystemer som krever minimalt
7565 av maskinvaren.

><strong
>Hvilken strategi tror du er den rette å bruke for å få
7568 skoler til å ta i bruk fri programvare?

7570 <p
>Tror en blanding av krav og informasjon er veien å gå. Krav om
7571 sikkerhet, oppetid og åpne standarder. Informasjon om muligheter og
7572 alternativer. Her har leverandører, IT-avdelinger og pedagoger en vei
7573 å gå sammen. Det er til slutt LÆRING det dreier seg om, og da må man
7574 få mest mulig læring for pengene man har.

>Sturle Sunde, ansvarleg for skulenettet i Flora kommune. Eg driv,
7592 vidareutviklar og er andrelinje brukarstøtte for datanettet ved
7593 skulane i Flora kommune.
10 skular og meir enn
700 maskiner med
7594 Linux, medrekna tynnklientar. Tidlegare jobba eg i mange år med
7595 unix-drift ved Universitetets senter for informasjonsteknologi ved
7596 Universitetet i Oslo.

7598 <p
><strong

7600 <p
>Det er vanskeleg å svare konkret på. Eg har drive med Unix og Linux i
7601 alle år, og Skulelinux er eit godt kjent prosjekt i miljøet. Det var
7602 først i
2008, då eg tok til i min noverande jobb, at eg fekk bruk for
7603 Skulelinux for alvor.
</p
>
7605 <p
>Jobben min skulle vere drift av eit nytt skulenett i Flora kommune,
7606 levert av eit firma eg ikkje vil reklamere for. Systemet skulle vere
7607 ferdig levert i september året før. Dette viste seg å ta mykje lenger
7608 tid, og i haustferien
2008 hadde dei endå ikkje klart å få opp ei
7609 fungerande løysing. Situasjonen var prekær for den største skulen i
7610 kommunen med meir enn
500 elevar på ungdomssteget. Skulen hadde brukt
7611 Skulelinux før, og var tilfredse med det. No hadde dei vore utan
7612 fungerande datasystem i nesten eit år. Difor fekk eg opp ein ny tenar
7613 utanfor prosjektet og installerte Skulelinux på den. Etter litt
7614 justering av konfigurasjonen med god hjelp av #skolelinux på IRC, var
7615 den nye tenaren oppe og gjekk med både tynne og halv-tjukke klientar.
7616 Autentisering gjekk mot det nye systemet, slik at elevar og lærarar
7617 framleis har same brukarnamn og passord over alt. Dette berre
7618 fungerte, og vi bestemte oss for å erstatte delar av løysinga vi
7619 skulle få levert med Skulelinux.
</p
>
7621 <p
>Det høyrer med til historia at det nye systemet eg skulle drive frå
7622 januar
2008 endå ikkje er ferdig levert. Dei jobbar med saka, seier
7623 dei, og har von om å fullføre leveransen i løpet av
2011.
</p
>
7625 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7627 <p
>Det er veldig mange. Eg skal ta nokre få.
</p
>
7629 <p
>Den viktigaste fordelen er at det igrunn berre er ei maskin å passe
7630 på, og det er tenaren. Med andre løysingar har ein gjerne programvare
7631 og anna som skal vedlikehaldast på kvar enkelt maskin. Med Skulelinux
7632 kan alle feil rettast og alle program oppgraderast på alle maskiner
7633 samstundes ved å gjere endringa som må til på tenaren. Eg kan sitje
7634 på kontoret og passe på alle tenarane i kommunen derifrå.
</p
>
7638 <li
>Tynne klientar gjer det mogleg å bruke eldre utstyr lenge, so lenge
7639 tenaren er sterk nok. Ein liten tenar med eit par halv-moderne CPUar
7640 og
2 GiB RAM held lenge for eit typisk klasserom med
30 tynnklientar,
7641 og det er lett å utvide med fleire.
7643 <li
>Halvtjukke klientar gjer det mogleg å utnytte kapasiteten i litt
7644 nyare maskiner betre, og avlaste tenaren. Ingenting vert installert
7645 lokalt på desse heller, og harddisken kan gjerne koblast frå. Gode
7646 halvtjukke klientar kan kjøpast brukt for under
1000-lappen, og det er
7647 heile kostnaden. Ingen lisensar eller anna på toppen, og det er ikkje
7648 krav til kraftigare tenar heller.
7650 <li
>Det er Linux. Vi har ikkje noko kluss med drivarar, dei berre er
7651 der. Heller ikkje med virus, dei finst i realiteten ikkje. Eller med
7652 elevar som klussar med installert programvare, for dei klarar ikkje å
7653 øydeleggje for nokon andre enn seg sjølve.
7657 <p
>Skulelinux er lagt opp til å vere veldig lett å installere rett ut
7658 av boksen på ein heil skule av ein interessert lærar. Det er ofte ei
7659 god løysing for skulen. Å ha nokon til stades som kjenner systemet og
7660 kan forklare enkle ting eller løyse problem der og då, er uvurderleg
7661 viktig for ein stressa lærar fem minutt før det ringer inn.
</p
>
7663 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7665 <p
>All den ferdige konfigurasjonen gjer det tungvint å tilpasse
7666 Skulelinux til eit system som skal fungere saman med mange andre
7667 installasjonar i eit felles datanett for skulane i ein kommune. Det
7668 heile er prekonfigurert for ein skule, og utviding til mange skular
7669 med eigne tenarar er ikkje berre enkelt.

7684 har råd til å kjøpe noko nytt og blankpussa opplegg. Der er det om å
7685 gjere å gjere det enkelt for skulane å finne Skulelinux, og gjere det
7686 enkelt for dei å få hjelp til installasjon på skulen. Gjerne med
7687 lokale kontaktpersonar. Her er det dugnadsinnsats som må til, for
7688 desse skulane har ikkje råd til å betale for dette.

7690 <p
>Den andre og kanskje viktigare målgruppa er dei meir eller mindre
7691 profesjonelle kundane. Alle store offentlege innkjøp, inkludert
7692 innkjøp av nytt datasystem for skular, må ut på offentleg anbod.
7693 Offentlege anbod er mykje meir lukka enn dei gjev inntrykk av, og både
7694 regelboka og boka med triks for å sminke tilbodet er tjukk. Det er
7695 vanskeleg å komme inn utan eit solid salsapparat i ryggen. Kanskje
7696 Skulelinux skulle prøve aktivt å få seg eit partnarskap med eit av dei
7697 store som gjerne vil sterkare inn på den offentlege IT-marknaden?
7698 Nokon som kjenner triksa og har krefter til å ta opp kampen mot både
7699 dårlege anbod og Rudolf Blostrupmoen IT AS. Leveranse til skulane i
7700 ein kommune er ein god måte å få ein fot inn døra som leverandør til
7701 ein lukrativ kommunemarknad som kjøper alle tenester. Ta kontakt med
7702 nokon som er passeleg store og ikkje er Microsoft-partnar, og fortell:
7703 «Vi har eit ferdig produkt som du kan selje. Nei vi skal ikkje ha for
7704 det. Du kan gjerne gjere kva du vil med det, berre vi får lov til å
7705 hjelpe deg. Målgruppa er alle kommunar, og det er noko dei vil ha.
7706 Det er eit godt produkt, brukt av mange og godt likt.»

>Embrik Kaslegard,
1964-modell, fire barn (
7-
20 år). Begynte som
7723 lærer i
1989 - har hatt IKT-ansvar siden første året i jobb. Har
7724 jobbet som lærer/IKT-ansvarlig uavbrutt siden
1989. Jobbet med
7725 Skolelinux fra
2004 til
2010. Nå har jeg fått ny arbeidsplass og er
7726 40% lærer og
60% IKT med Windows XP, Win2003 server og et regionalt
7727 IKT-regime som legger premissene og begrensingene for hva vi kan gjøre
7728 på skolen.

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

7732 <p
>Jeg leste en artikkel om en dugnadsinstallasjon av Skolelinux på en
7733 skole på Jæren et sted. Tanken om dugnad og frihet appellerte til
7734 meg. Da vi skulle bygge ny skole var det en del vi måtte spare på,
7735 fordi vi beveget oss mot en kostnadssprekk. Kabling og investering i
7736 PC-er var en av tingene vi sparte på. Derfor kjøpe vi
72 pc-er for
390
7737 pr stk. En filtjener og en applikasjonsserver.

7739 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7741 <p
>Fordelen er at så mye er satt opp fra starten. I tillegg er det
7742 tydelig at pakka er laga for skoleverket. Brukerne har egne
7743 skrivebord, tilgang på mange gode verktøyprogrammer. Vi slipper å
7744 tenke på virus. Brukerne har ikke mulighet til å ødelegge
7745 klientoppsett, men har gode muligheter til å endre eget oppsett. Dette
7746 tror jeg er inspirerende og kjekt for mange brukere. Mappestrukturen
7747 er ferdig og det er
"enkelt
" å designe lokale mappestrukturer via
7748 skeleton. Noen av oss i skoleverket mener skolen skal være en
7749 "mot-kultur
". Da er Skolelinux et av valgene man kan ta. Et annet er å
7750 spise på indisk restaurant i stedet for Mc Donald
's når vi er på bytur
7751 osv.. Ordene deling, frihet, dugnad osv er positive ord i
7752 skoleverket. Det er viktig at elevene blir bevisst dette.
</p

7754 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
7756 <p
>Kompabiliteten er selvsagt et problem, selv om det er mindre nå enn
7757 før. For IKT-personer på skolene som skal drifte dette er det
7758 problematisk med kommandoer i terminalen. I tillegg er det alt for
7759 mange programmer i Skolelinux som ikke blir brukt. Jeg tror
7760 Skolelinux er tjent med å tone ned begrepet pedagogisk programvare.
7761 Slik jeg ser det finnes ikke denne kategorien programmer lengre slik
7762 de gjorde før, som frittsående programmer som installeres på en
7763 datamaskin eller på serveren. Det finnes en del spesialpedagogiske
7764 programmer, som Textpilot, LingDys, LingRight, AskiRaski, Ny i Norge
7765 osv. Men dette er programmer for enkelt-elever eller små grupper av
7766 elever. Det som bør være fokus er at alle undervisningsressurser som
7767 lages for nettet skal være nettleseruavhengig.

7769 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
7771 <p
>OpenOffice bruker jeg til vanlig kontorarbeide. VLC bruker jeg som
7772 videoavspiller og av og til streaming av film. Gimp bruker jeg i
7773 undervisningen til bildemanipulering. Firefox og Chrome er mine
7774 favoritt-nettlesere. Firefox har lenge vært førstevalget mitt, nå
7775 bruker jeg mest Chrome. Opplever den som raskere og smidigere enn
7776 Firefox. Ubuntu bruker jeg som dualboot på jobb-maskinen min i
7777 tillegg til at alle PCer hjemme har en eller annen Ubuntu-distribusjon
7778 installert. Jeg bruker Clonezilla på Ubuntu
10.04 til kloning av
7779 datamaskiner på jobb. Det er selvsagt en haug andre frie programmer
7780 jeg bruker men jeg bruker dem ikke daglig. Jeg kan ramse opp:
7781 recordmydesktop, cinelerra, acidrip, soundjuicer, audacity, NX
7782 (no-machine), Kino, Rythmbox...

7784 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
7785 skoler til å ta i bruk fri programvare?
</strong
></p
>
7787 <p
>Jeg tror oppsøkende virksomhet er den rette strategien.
7788 Ressurspersoner gjør avtaler med rådmenn, skolesjefer, rektorer. Det
7789 er slik konkurrentene gjør det. Fokuset i slike samtaler bør være
7790 kost-nytte. Dersom personer med økonomisk ansvar ser at de kan få
7791 like godt tilbud til mindre utgifter, tror jeg det er mulighet til å
7792 få innpass. Dersom de også kan få konkrete tilbud på drift i slike
7793 samtaler, vil de kanskje bli litt mer interesserte i hvor mye penger
7794 som faktisk går til IKT i skolene. Det er også viktig at vi ikke
7795 firer for mye på krav til datamaskiner. Det er flott at Skolelinux
7796 går på
"utrangert
" utstyr, men dette bør bare presenteres som et
7797 alternativ. Skolelinux-installasjoner med utrangert utstyr er ikke å
7798 foretrekke dersom man kan unngå det. Det skaper ikke entusiasme hos
7799 brukerne (elever og lærere) når de bruker gamle datamaskiner som går
7800 tregt. Det er kjempefint med skoler som har kommet seg frem til
7801 Skolelinux og fri programvare av seg selv, men de lever på nåde.
7802 Slike valg må fundamenteres hos skoleeier.

17
7826 servere basert på Skolelinux og Debian. Jeg holder i tillegg noen kurs
7827 mellom all driftingen. For tiden arbeider jeg med en sentral

7833 <p
>Gjennom en eller annen nettavis i
2001 der var det skrevet om
7834 Skolelinux. Artikkelen ga meg lyst til å prøve ut systemet.
</p
>
7836 <p
>Det startet i
2002 ved at jeg installerte en av de første utgavene
7837 av Skolelinux på en standard pc på Solneset skole i Tromsø. Denne var
7838 oppe fram til desember
2003 da jeg sluttet på den skolen og begynte i
7839 ny jobb i Narvik kommune.
</p

7841 <p
> I Narvik kommune var det i
2004 kun
2 servere på da totalt
15
7842 skoler. Disse var Windows NT baserte. På disse to skolene var det lite
7843 med maskiner. Jobben med å få Narvik Kommune opp på akseptabelt nivå
7844 virket å være formidabel. Men med hjelp av gode kollegaer og leder
7845 skrev jeg en IKT plan for Narvik kommune som ble vedtatt av politikere
7846 i august
2004. I denne planen ble det bestemt at Narvik kommune skulle
7847 bruke Skolelinux. Her ble det også satt av midler til kabling av god
7848 infrastruktur på alle skoler samt innkjøp av nye datamaskiner. Så i
7849 dag har vi
17 servere hvorav
13 er på Skolelinux, med ca
1500 klienter
7850 basert på tynne,
"halvtykke
" og et stort antall bærbare pcer basert på

7867 <p

7868 nettbaserte programmer istedet for å installere lokalt. Dette med
7869 enkelte leverandører som ikke kan levere programmer til Linux er et
7870 lite problem og over tid tror jeg at denne barrieren er borte.

7933 men det virker ut som det ikke skjer noe mer på. I tillegg var vi med

7983 <br

7985 <p
>Kommunen min har to omtrent jevnstore tettsteder, og en
7986 ungdomsskole i hvert av tettstedene. Den minste av disse har ca
300
7987 elever og til denne sogner det
3 barneskoler. Den største har ca
350
7988 elever og til denne sogner det
4 barneskoler.
</p
>
7992 <li
>Kommunen har i veldig lang tid forsømt IKT i skolen, og det har
7993 bare blitt gitt smuler i ny og ne. Det er kun den største av
7994 ungdomsskolene som har hatt en skikkelig datapark, og dette takket
7995 være en naturfaglærer som ble lei av å vente på kommunen. Det gjorde
7996 at vi bestemte oss for å ta ting i egne hender, og da vha
7997 skolelinux. En testinstallasjon med
10 gamle PCer ble gjort, og vi så
7998 raskt at dette var veldig lovende. Neste etappe var å gi alle lærere
7999 egen PC på arbeidsplassene sine (
2004), og så sette opp
16 PCer på to
8000 datarom. Vi har kun basert oss på å kjøpe inn brukte maskiner, og
8001 aldri dyrere enn
1000 kr pr klient. For to år siden så hadde vi
8002 klienter i alle klasserom, og totalt hadde vi da rundt
250 stk. Rundt
8003 40 klienter brukes av lærerne og kjører på en egen server. Elvene har
8004 resten, og kjører også en egen server. Servere har vi også kjøpt
8005 brukt,
2 år gamle servere koster
6-
7000 kroner.
</li
>
8007 <li
>Skolen vår er et relativt gammelt bygg, men en meget dyktig
8008 vaktmester har sammen med IKT-ansvarlig/Naturfaglærer lagt kabler til alle
8009 rom. Gradvis har vi byttet ut billige svitsjer med mer solide saker
8010 som er mulig å fjernstyre.
</li
>
8012 <li
>Vi har i all hovedsak greid å få dette til over eget budsjett, men
8013 vi har også passet på å få penger når de andre skolene har fått
8014 bærbare PCer til lærere osv.
</li
>
8016 <li
>Vår IKT-ansvarlig har gjort (og gjør) en fenomenal jobb, og vi har
8017 en maskinpark som de andre av kommunens skoler bare kan drømme
8022 <p
>Så skjer det som ofte skjer. Det kommer en eller annen
8023 selger/blåruss og skal fikse ALT. I vårt tilfelle betyr dette også
8024 sentralisering av drift. Den ny-ansatte på kommunens IT-avdelingen
8025 skal også ha jobb, og ser for seg å ta over skoledriften. Kommunen
8026 kjøper inn eksterne driftstjenester, og nekter i samme slengen å ta
8027 hensyn til skolen vår. Dette til tross for at vi alene har like mange
8028 datamaskiner som de andre til sammen.
</p
>
8032 <li
>Det blir krevd at vi skal innlemmes i de kommunale systemet, og
8033 det er VI som får ansvar for at dette kommer på plass. Og det er her
8034 de horrible tingene begynner å skje.
</li

8037 hente epost for våre ansatte. Og det kreves at vi finner løsning på

8041 at vi må bruke en terminalløsning mot kommunal server. Ikke i seg selv
8042 et problem i følge IKT-ansvarlig hos oss. Men kommunens IT-avd nektet
8043 faktisk å åpne de porter OSV som vi måtte bruke.

8057 sitte ved hver sin PC. Og de har fått tilbakemelding (klager) fra VGS
8058 om manglende datakompetanse på elevene som kommer fra dem. Dette fører
8059 videre til at kommunen endelig innser at de må ta grep.

8064 og det skal satses på bærbare maskiner. Siden vi ikke har fått tatt
8065 del i prosessene som angår oss, så bruker vi fagforening. Vi har ikke
8066 blitt hørt i forbindelse med endringer som er betydelig for vår
8067 hverdag, og greier å stoppe omlegging. I tillegg så har vi et politisk
8068 vedtak i kommunen på at vi skal kjøre Linux på elevnett, og dette

8147 flere brudd på anbudsregler, og vi kjenner til at relativt store

8155 <p
>Jeg glemte å nevne at vi nå nesten ikke bruker tid på å drifte
8156 systemet vårt, noe som gjør at det aller meste av tid blir brukt til å
8157 støtte lærerne og elevene. F.eks så bruker vår IKT-ansvarlig den
8158 første timen på jobb,
0730-
0830 kun til å gå ute på arbeidsplassene
8159 til læreren. Dette for å kunne svare på små og store problem, gi tips
8160 og råd, eller bare for å plukke opp hva som er behovet ute i
8161 undervisningsarealene. Det er dessverre ikke slik at alle lærerne har
8162 nok digital kompetanse til å kunne formulere alle spørsmålene de har,
8163 men ved å kunne få vise eller lufte tanker med IKT-ansvarlig så er det
8164 utrolig hva som kommer fram.
</p
>
8168 <li
>Jeg ser at mange bruker økonomi som argument i forhold til å bruke
8169 SkoleLinux, og jeg skal ikke legge skjul på at det var dette som i
8170 utgangspunktet var årsaken til vårt valg. Men diskusjonene og kampen
8171 med kommunens IT-avdeling har gjort at vi har fått et noe annet
8172 fokus. Fordelene med drift og stabilitet, gjør at vi ville ha valgt
8173 samme løsning selv om den var dyrere. At vi slipper langt billigere
8174 unna, som følge av
0,- lisenskostnader og lave maskinvarekostnader, er
8175 bare en bonus.
</li
>
8177 <li
>Etter å ha kranglet oss til å få skikkelig oversikt over hva de
8178 andre skolene i kommunen bruker på IT, så har vi fått gehør for å få
8179 samme midler til innkjøp. Dette har gjort at vi nå kan kjøpe inn
8180 utstyr som de andre skolene bare kan se langt etter. Vi har nettopp
8181 kjøpt inn
3 videokamera i semiproff-klassen for å kunne lage film,
8182 samt sende live fra skoleteater/konserter. Vi har kjøpt inn digitale
8183 kompaktkamera til alle klassene. Vi har et team av lærere som skal i
8184 gang med å teste ut tablets på svake elever. Håpet et at teknologien
8185 kan være med på å gi noen av elevene litt mer motivasjon. Vi har kjøpt
8186 inn et halvt klassesett med pulsklokker, noe som har vist seg å være
8187 overraskende inspirerende for en del av elevene. Vi har også oss på
8188 fag på en høyskole litt lengre sør for oss, slik at
3 av oss nå skal
8189 ta faget
"Linux tjenestedrift
". Som inspektør og en del av skolens
8190 administrasjon er det veldig praktisk å kunne trå til hvis det
8191 kniper. Men IKT-ansvarlig har vært UTROLIG flink til å lage rene
8192 smørbrødlister for hvordan de mest vanlige driftsproblem løses, så det
8193 er lett for flere av oss å ta del i den daglige driften. Vi har svært
8194 stor nytte av lærling (som også hjelper to av naboskolene), men det er
8195 nesten blitt slik at det er om å gjøre å komme til først for å få løse
8196 problem. Det å få fingrene på problem og utfordringer er den aller
8197 beste læremester.

8210 håper at vi nå framover kan få tid til å bidra. Vi er i ferd med å
8211 bytte ut en av serverne våre, og da vil denne trolig bli satt opp som
8212 testserver for neste versjon av Skolelinux. På den måten vil vi i alle
8213 fall kunne gi tilbakemeldinger og rapportere feil. I tillegg så vil
8214 det kanskje gi oss noen nye utfordringer, for som lærlingen vår sier:

8347 <description><p
>In the latest issue of Linux Journal, the readers choices were
8348 presented, and the winner among the multimedia player were VLC.
8349 Personally, I like VLC, and it is my player of choice when I first try
8350 to play a video file or stream. Only if VLC fail will I drag out
8351 gmplayer to see if it can do better. The reason is mostly the failure
8352 model and trust. When VLC fail, it normally pop up a error message
8353 reporting the problem. When mplayer fail, it normally segfault or
8354 just hangs. The latter failure mode drain my trust in the program.
<p
>
8356 <p
>But even if VLC is my player of choice, we have choosen to use
8357 mplayer in
<a href=
"http://www.skolelinux.org/
">Debian
8358 Edu/Skolelinux
</a
>. The reason is simple. We need a good browser
8359 plugin to play web videos seamlessly, and the VLC browser plugin is
8360 not very good. For example, it lack in-line control buttons, so there
8361 is no way for the user to pause the video. Also, when I
8362 <a href=
"http://wiki.debian.org/DebianEdu/BrowserMultimedia
">last
8363 tested the browser plugins
</a
> available in Debian, the VLC plugin
8364 failed on several video pages where mplayer based plugins worked. If
8365 the browser plugin for VLC was as good as the gecko-mediaplayer
8366 package (which uses mplayer), we would switch.
</P
>
8368 <p
>While VLC is a good player, its user interface is slightly
8369 annoying. The most annoying feature is its inconsistent use of
8370 keyboard shortcuts. When the player is in full screen mode, its
8371 shortcuts are different from when it is playing the video in a window.
8372 For example, space only work as pause when in full screen mode. I
8373 wish it had consisten shortcuts and that space also would work when in
8374 window mode. Another nice shortcut in gmplayer is [enter] to restart
8375 the current video. It is very nice when playing short videos from the
8376 web and want to restart it when new people arrive to have a look at
8377 what is going on.

8833 are virtual machines. And they have been Xen machines running on a
8834 fairly old IBM eserver xseries
345 machine, and we wanted to migrate
8835 them to KVM on a newer Dell PowerEdge
2950 host machine. This was a
8836 bit harder that it could have been, because we set up the Xen virtual
8837 machines to get the virtual partitions from LVM, which as far as I
8838 know is not supported by KVM. So to migrate, we had to convert
8839 several LVM logical volumes to partitions on a virtual disk file.

8843 nice recipe
</a

8844 migration. It uses qemu-img from the qemu package to make the disk
8845 image, parted to partition it, losetup and kpartx to present the disk
8846 image partions as devices, and dd to copy the data. I NFS mounted the
8847 new servers storage area on the old server to do the migration.

9144 machine as well. I have also considered using the kfreebsd
9145 architecture in Debian as a file server in NUUG to get access to the
5
9146 TB zfs volume we currently use to store DV video. Because of this, I
9147 finally got around to do a test installation of Debian/Squeeze with
9148 kfreebsd. Installation went fairly smooth, thought I noticed some
9149 visual glitches in the cdebconf dialogs (black cursor left on the
9150 screen at random locations). Have not gotten very far with the
9151 testing. Noticed cfdisk did not work, but fdisk did so it was not a
9152 fatal problem. Have to spend some more time on it to see if it is
9153 useful as a file server for NUUG. Will try to find time to set up a
9154 gnash buildbot slave on the Debian Edu/Skolelinux this weekend.

9165 supposed provide a school with all the services and user applications
9166 needed on the pupils computer network has always been hard. Even
9167 schools without Internet connections should be able to get Debian Edu
9168 working using this DVD.
</p
>
9170 <p
>The job became a lot harder when apt and aptitude started
9171 installing recommended packages by default. We want the same set of
9172 packages to be installed when using the DVD and the netinst CD, and
9173 that means all recommended packages need to be on the DVD. I created
9174 a patch for debian-cd in
<a href=
"http://bugs.debian.org/
601203">BTS
9175 report #
601203</a
> to do this, and since this change was applied to
9176 the Debian Edu DVD build, we have been seriously short on space.
</p
>
9178 <p
>A few days ago we decided to drop blender, wxmaxima and kicad from
9179 the default installation to save space on the DVD, believing that
9180 those needing these applications are few and can get them from the
9181 Debian archive.
</p
>
9183 <p
>Yesterday, I had a look what source packages to see which packages
9184 were using most space. A few large packages are well know;
9185 openoffice.org, openclipart and fluid-soundfont. But I also
9186 discovered that lilypond used
106 MiB and fglrx-driver used
53 MiB.
9187 The lilypond package is pulled in as a dependency for rosegarden, and
9188 when looking a bit closer I discovered that
99 MiB of the
106 MiB were
9189 the documentation package, which is recommended by the binary package.
9190 I decided to drop this documentation package from our DVD, as most of
9191 our users will use the GUI front-ends and do not need the lilypond
9192 documentation. Similarly, I dropped the non-free fglrx-driver package
9193 which might be installed by d-i when its hardware is detected, as the
9194 free X driver should work.
</p
>
9196 <p
>With this change, we finally got space for the LXDE and Gnome
9197 desktop packages as well as the language specific packages making the
9198 DVD more useful again.

9212 More signers and more funding is most welcome, and I am really curious
9213 how far we can get before the time limit of December
24 is reached.
9216 <p

9217 about what appear to be a great code coverage tool capable of
9218 generating code coverage stats without any changes to the source code.

9222 It is missing in Debian, but the git source built just fine in Squeeze
9223 after I installed libelf-dev, libdwarf-dev, pkg-config and
9224 libglib2.0-dev. Failed to build in Lenny, but suspect that is
9225 solvable. I hope kcov make it into Debian soon.

9257 schools experienced with
<a href=
"http://www.skolelinux.org/
">Debian
9258 Edu/Skolelinux
</a
> was the lack of working Flash. A lot of educational
9259 web sites require Flash to work, and lacking working Flash support in
9260 the web browser and the problems with installing it was perceived as a
9261 good reason to stay with Windows.
</p

9263 <p
>I once saw a funny and sad comment in a web forum, where Linux was
9264 said to be the retarded cousin that did not really understand
9265 everything you told him but could work fairly well. This was a
9266 comment regarding the problems Linux have with proprietary formats and
9267 non-standard web pages, and is sad because it exposes a fairly common
9268 understanding of whose fault it is if web pages that only work in for
9269 example Internet Explorer
6 fail to work on Firefox, and funny because
9270 it explain very well how annoying it is for users when Linux
9271 distributions do not work with the documents they receive or the web
9272 pages they want to visit.
</p
>
9274 <p
>This is part of the reason why I believe it is important for Debian
9275 and Debian Edu to have a well working Flash implementation in the
9276 distribution, to get at least popular sites as Youtube and Google
9277 Video to working out of the box. For Squeeze, Debian have the chance
9278 to include the latest version of Gnash that will make this happen, as
9279 the new release
0.8.8 was published a few weeks ago and is resting in
9280 unstable. The new version work with more sites that version
0.8.7.
9281 The Gnash maintainers have asked for a freeze exception, but the
9282 release team have not had time to reply to it yet. I hope they agree
9283 with me that Flash is important for the Debian desktop users, and thus
9284 accept the new package into Squeeze.

>As reported earlier, the last few days I have looked at how Debian
9459 Edu clients are configured, and tried to get rid of all hardcoded
9460 configuration settings on the clients. I believe the work to be
9461 mostly done, and the clients seem to work just fine with dynamically
9462 generated configuration.
</p
>
9464 <p
>What is the point, you might ask? The point is to allow a Debian
9465 Edu desktop to integrate into an existing network infrastructure
9466 without any manual configuration.
</p
>
9468 <p
>This is what happens when installing a Debian Edu client here at
9469 the University of Oslo using PXE. With the PXE installation, I am
9470 asked for language (Norwegian Bokmål), locality (Norway) and keyboard
9471 layout (no-latin1), Debian Edu profile (Roaming Workstation), if I
9472 accept to reformat the hard drive (yes), if I want to submit info to
9473 popcon.debian.org (no) and root password (secret). After answering
9474 these questions, the installer goes ahead and does its thing, and
9475 after around
50 minutes it is done. I press enter to finish the
9476 installation, and the machine reboots into KDE. When the machine is
9477 ready and kdm asks for login information, I enter my university
9478 username and password, am told by kdm that a local home directory has
9479 been created and that I must log in again, and finally log in with the
9480 same username and password to the KDE
4.4 desktop. At no point during
9481 this process did it ask for university specific settings, and all the
9482 required configuration was dynamically detected using information
9483 fetched via DHCP and DNS. The roaming workstation is now ready for
9486 <p
>How was this done, you might wonder? First of all, here is the
9487 list of things that need to be configured on the client to get it
9488 working properly out of the box:
</p
>
9491 <li
>IP address/netmask and DNS server.
</li
>
9492 <li
>Web proxy URL.
</li
>
9493 <li
>LDAP server for NSS directory information (user, group, etc).
</li
>
9494 <li
>Kerberos server for PAM password checking.
</li
>
9495 <li
>SMB mount point to access the network home directory. (*)
</li
>
9496 <li
>Central syslog server to send syslog messages to. (*)
</li
>
9497 <li
>Sitesummary collector URL to submit info to central server. (*)
</li
>
9500 <p
>(Hm, did I forget anything? Let me knew if I did.)
</p
>
9502 <p
>The points marked (*) are not required to be able to use the
9503 machine, but needed to provide central storage and allowing system
9504 administrators to track their machines. Since yesterday, everything
9505 but the sitesummary collector URL is dynamically discovered at boot
9506 and installation time in the svn version of Debian Edu.
</p
>
9508 <p
>The IP and DNS setup is fetched during boot using DHCP as usual.
9509 When a DHCP update arrives, the proxy setup is updated by looking for
9510 http://wpat/wpad.dat and using the content of this WPAD file to
9511 configure the http and ftp proxy in /etc/environment and
9512 /etc/apt/apt.conf. I decided to update the proxy setup using a DHCP
9513 hook to ensure that the client stops using the Debian Edu proxy when
9514 it is moved outside the Debian Edu network, and instead uses any local
9515 proxy present on the new network when it moves around.
</p
>
9517 <p
>The DNS names of the LDAP, Kerberos and syslog server and related
9518 configuration are generated using DNS information at boot. First the
9519 installer looks for a host named ldap in the current DNS domain. If
9520 not found, it looks for _ldap._tcp SRV records in DNS instead. If an
9521 LDAP server is found, its root DSE entry is requested and the
9522 attributes namingContexts and defaultNamingContext are used to
9523 determine which LDAP base to use for NSS. If there are several
9524 namingContexts attibutes and the defaultNamingContext is present, that
9525 LDAP subtree is used as the base. If defaultNamingContext is missing,
9526 the subtrees listed as namingContexts are searched in sequence for any
9527 object with class posixAccount or posixGroup, and the first one with
9528 such an object is used as the LDAP base. For Kerberos, a similar
9529 search is done by first looking for a host named kerberos, and then
9530 for the _kerberos._tcp SRV record. I
've been unable to find a way to
9531 look up the Kerberos realm, so for this the upper case string of the
9532 current DNS domain is used.
</p
>
9534 <p
>For the syslog server, the hosts syslog and loghost are searched
9535 for, and the _syslog._udp SRV record is consulted if no such host is
9536 found. This algorithm works for both Debian Edu and the University of
9537 Oslo. A similar strategy would work for locating the sitesummary
9538 server, but have not been implemented yet. I decided to fetch and
9539 save these settings during installation, to make sure moving to a
9540 different network does not change the set of users being allowed to
9541 log in nor the passwords required to log in. Usernames and passwords
9542 will be cached by sssd when the user logs in on the Debian Edu
9543 network, and will not change as the laptop move around. For a
9544 non-roaming machine, there is no caching, but given that it is
9545 supposed to stay in place it should not matter much. Perhaps we
9546 should switch those to use sssd too?
</p
>
9548 <p
>The user
's SMB mount point for the network home directory is
9549 located when the user logs in for the first time. The LDAP server is
9550 consulted to look for the user
's LDAP object and the sambaHomePath
9551 attribute is used if found. If it isn
't found, the home directory
9552 path fetched from NSS is used instead. Assuming the path is of the
9553 form /site/server/directory/username, the second part is looked up in
9554 DNS and used to generate a SMB URL of the form
9555 smb://server.domain/username. This algorithm works for both Debian
9556 edu and the University of Oslo. Perhaps there are better attributes
9557 to use or a better algorithm that works for more sites, but this will
9558 do for now. :)

9560 <p
>This work should make it easier to integrate the Debian Edu clients
9561 into any LDAP/Kerberos infrastructure, and make the current setup even
9562 more flexible than before. I suspect it will also work for thin
9563 client servers, allowing one to easily set up LTSP and hook it into a
9564 existing network infrastructure, but I have not had time to test this

2010-

09: Simon Farnsworth gave me a heads-up on how to
9571 detect Kerberos realm from DNS, by looking for _kerberos TXT entries
9572 before falling back to the upper case DNS domain name. Will have to
9573 implement it for Debian Edu. :)

9582 <description><p
>A few years ago, I was involved in a project planning to use
9583 Windows file servers as home directory servers for Debian
9584 Edu/Skolelinux machines. This was thought to be no problem, as the
9585 access would be through the SMB network file system protocol, and we
9586 knew other sites used SMB with unix and samba as the file server to
9587 mount home directories without any problems. But, after months of
9588 struggling, we had to conclude that our goal was impossible.
</p
>
9590 <p
>The reason is simply that while SMB can be used for home
9591 directories when the file server is Samba running on Unix, this only
9592 work because of Samba have some extensions and the fact that the
9593 underlying file system is a unix file system. When using a Windows
9594 file server, the underlying file system do not have POSIX semantics,
9595 and several programs will fail if the users home directory where they
9596 want to store their configuration lack POSIX semantics.
</p
>
9598 <p
>As part of this work, I wrote a small C program I want to share
9599 with you all, to replicate a few of the problematic applications (like
9600 OpenOffice.org and GCompris) and see if the file system was working as
9601 it should. If you find yourself in spooky file system land, it might
9602 help you find your way out again. This is the fs-test.c source:

>A few days ago, I
9814 <a href=
"http://people.skolelinux.org/pere/blog/Debian_Edu_roaming_workstation___at_the_university_of_Oslo.html
">tried
9815 to install
</a
> a Roaming workation profile from Debian Edu/Squeeze
9816 while on the university network here at the University of Oslo, and
9817 noticed how much had to change to get it operational using the
9818 university infrastructure. It was fairly easy, but it occured to me
9819 that Debian Edu would improve a lot if I could get the client to
9820 connect without any changes at all, and thus let the client configure
9821 itself during installation and first boot to use the infrastructure
9822 around it. Now I am a huge step further along that road.
</p
>
9824 <p
>With our current squeeze-test packages, I can select the roaming
9825 workstation profile and get a working laptop connecting to the
9826 university LDAP server for user and group and our active directory
9827 servers for Kerberos authentication. All this without any
9828 configuration at all during installation. My users home directory got
9829 a bookmark in the KDE menu to mount it via SMB, with the correct URL.
9830 In short, openldap and sssd is correctly configured. In addition to
9831 this, the client look for http://wpad/wpad.dat to configure a web
9832 proxy, and when it fail to find it no proxy settings are stored in
9833 /etc/environment and /etc/apt/apt.conf. Iceweasel and KDE is
9834 configured to look for the same wpad configuration and also do not use
9835 a proxy when at the university network. If the machine is moved to a
9836 network with such wpad setup, it would automatically use it when DHCP
9837 gave it a IP address.
</p
>
9839 <p
>The LDAP server is located using DNS, by first looking for the DNS
9840 entry ldap.$domain. If this do not exist, it look for the
9841 _ldap._tcp.$domain SRV records and use the first one as the LDAP
9842 server. Next, it connects to the LDAP server and search all
9843 namingContexts entries for posixAccount or posixGroup objects, and
9844 pick the first one as the LDAP base. For Kerberos, a similar
9845 algorithm is used to locate the LDAP server, and the realm is the
9846 uppercase version of $domain.
</p
>
9848 <p
>So, what is not working, you might ask. SMB mounting my home
9849 directory do not work. No idea why, but suspected the incorrect
9850 Kerberos settings in /etc/krb5.conf and /etc/samba/smb.conf might be
9851 the cause. These are not properly configured during installation, and
9852 had to be hand-edited to get the correct Kerberos realm and server,
9853 but SMB mounting still do not work. :(
</p
>
9855 <p
>With this automatic configuration in place, I expect a Debian Edu
9856 roaming profile installation would be able to automatically detect and
9857 connect to any site using LDAP and Kerberos for NSS directory and PAM
9858 authentication. It should also work out of the box in a Active
9859 Directory environment providing posixAccount and posixGroup objects
9860 with UID and GID values.

>The new roaming workstation profile in Debian Edu/Squeeze is fairly
9873 similar to the laptop setup am I working on using Ubuntu for the
9874 University of Oslo, and just for the heck of it, I tested today how
9875 hard it would be to integrate that profile into the university
9876 infrastructure. In this case, it is the university LDAP server,
9877 Active Directory Kerberos server and SMB mounting from the Netapp file
9880 <p
>I was pleasantly surprised that the only three files needed to be
9881 changed (/etc/sssd/sssd.conf, /etc/ldap.conf and
9882 /etc/mklocaluser.d/
20-debian-edu-config) and one file had to be added
9883 (/usr/share/perl5/Debian/Edu_Local.pm), to get the client working.
9884 Most of the changes were to get the client to use the university LDAP
9885 for NSS and Kerberos server for PAM, but one was to change a hard
9886 coded DNS domain name in the mklocaluser hook from .intern to
9889 <p
>This testing was so encouraging, that I went ahead and adjusted the
9890 Debian Edu scripts and setup in subversion to centralise the roaming
9891 workstation setup a bit more and avoid the hardcoded DNS domain name,
9892 so that when I test this tomorrow, I expect to get away with modifying
9893 only /etc/sssd/sssd.conf and /etc/ldap.conf to get it to use the
9894 university servers.
</p

9896 <p
>My goal is to get the clients to have no hardcoded settings and
9897 fetch all their initial setup during installation and first boot, to
9898 allow them to be inserted also into environments where the default
9899 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
10030 been working hard to get the Debian/Squeeze based version of Debian
10031 Edu/Skolelinux into shape. This future version will use Kerberos for
10032 authentication, and services are slowly migrated to single signon,
10033 getting rid of password questions one at the time.
</p
>
10035 <p
>It will also feature a roaming workstation profile with local home
10036 directory, for laptops that are only some times on the Skolelinux
10037 network, and for this profile a shortcut is created in Gnome and KDE
10038 to gain access to the users home directory on the file server. This
10039 shortcut uses SMB at the moment, and yesterday I had time to test if
10040 SMB mounting had started working in KDE after we added the cifs-utils
10041 package. I was pleasantly surprised how well it worked.
</p
>
10043 <p
>Thanks to the recent changes to our samba configuration to get it
10044 to use Kerberos for authentication, there were no question about user
10045 password when mounting the SMB volume. A simple click on the shortcut
10046 in the KDE menu, and a window with the home directory popped
10049 <p
>One step closer to a single signon solution out of the box in
10050 Debian Edu. We already had PAM, LDAP, IMAP and SMTP in place, and now
10051 also Samba. Next step is Cups and hopefully also NFS.

10053 <p
>We had planned a alpha0 release of Debian Edu for today, but thanks
10054 to the autobuilder administrators for some architectures being slow to
10055 sign packages, we are still missing the fixed LTSP package we need for
10056 the release. It was uploaded three days ago with urgency=high, and if
10057 it had entered testing yesterday we would have been able to test it in
10058 time for a alpha0 release today. As the binaries for ia64 and powerpc
10059 still not uploaded to the Debian archive, we need to delay the alpha
10060 release another day.

10080 <p
>As a step to try to see if it possible to merge the DNS and DHCP
10081 LDAP objects, I have had a look at how the packages pdns-backend-ldap
10082 and dhcp3-server-ldap in Debian use the LDAP server. The two
10083 implementations are quite different in how they use LDAP.
</p

10085 To get this information, I started slapd with debugging enabled and
10086 dumped the debug output to a file to get the LDAP searches performed

>PowerDNS have two modes of operation using LDAP as its backend.
10096 One
"strict
" mode where the forward and reverse DNS lookups are done
10097 using the same LDAP objects, and a
"tree
" mode where the forward and
10098 reverse entries are in two different subtrees in LDAP with a structure
10099 based on the DNS names, as in tjener.intern and
10100 2.2.0.10.in-addr.arpa.
</p
>
10102 <p
>In tree mode, the server is set up to use a LDAP subtree as its
10103 base, and uses a
"base
" scoped search for the DNS name by adding
10104 "dc=tjener,dc=intern,

10,dc=in-addr,dc=arpa,
" with a filter for
10107 "(associateddomain=
2.2.0.10.in-addr.arpa)
" for the reverse entry. For
10108 forward entries, it is looking for attributes named dnsttl, arecord,

10110 txtrecord, rprecord, afsdbrecord, keyrecord, aaaarecord, locrecord,

10402 we switch powerdns to use its strict LDAP method (ldap-method=strict

>Vagrant mentioned on IRC today that ltsp_config now support
10457 sourcing files from /usr/share/ltsp/ltsp_config.d/ on the thin
10458 clients, and that this can be used to fetch configuration from LDAP if
10459 Debian Edu choose to store configuration there.
</p

10461 <p
>Armed with this information, I got inspired and wrote a test module
10462 to get configuration from LDAP. The idea is to look up the MAC
10463 address of the client in LDAP, and look for attributes on the form
10464 ltspconfigsetting=value, and use this to export SETTING=value to the
10465 LTSP clients.

10467 <p

10468 in a

10469 allowing us to store all information about a computer in one place.

10471 <p

10660 <description><p
>For a laptop, centralized user directories and password checking is
10661 a bit troubling. Laptops are typically used also when not connected
10662 to the network, and it is vital for a user to be able to log in or
10663 unlock the screen saver also when a central server is unavailable.
10664 This is possible by caching passwords and directory information (user
10665 and group attributes) locally, and the packages to do so are available
10666 in Debian. Here follow two recipes to set this up in Debian/Squeeze.
10667 It is also possible to set up in Debian/Lenny, but require more manual
10668 setup there because pam-auth-update is missing in Lenny.
</p
>
10670 <h2
>LDAP/Kerberos + nscd + libpam-ccreds + libpam-mklocaluser/pam_mkhomedir
</h2
>
10672 This is the traditional method with a twist. The password caching is
10673 provided by libpam-ccreds (version
10-
4 or later is needed on
10674 Squeeze), and the directory caching is done by nscd. The directory
10675 lookup and password checking is done using LDAP. If one want to use
10676 Kerberos for password checking the libpam-ldapd package can be
10677 replaced with libpam-krb5 or libpam-heimdal. If one is happy having a
10678 local home directory with the path listed in LDAP, one can use the
10679 pam_mkhomedir module from pam-modules to make this happen instead of
10680 using libpam-mklocaluser. A setup for pam-auth-update to enable
10681 pam_mkhomedir will have to be written until a fix for
10682 <a href=
"http://bugs.debian.org/
568577">bug #
568577</a
> is in the
10683 archive. Because I believe it is a bad idea to have local home
10684 directories using misleading paths like /site/server/partition/, I
10685 prefer to create a local user with the home directory in /home/. This
10686 is done using the libpam-mklocaluser package.

10790 LDAP database is available. I have not tested such setup, because I
10791 discovered sssd.

10798 It is part of the
<a href=

10799 to provide a Active Directory like directory service for Linux
10800 machines. The sssd system combines the caching of passwords and user
10801 information into one package, and remove the need for nscd and
10802 libpam-ccreds. It support LDAP and Kerberos, but not NIS. Version
10803 1.2 do not support netgroups, but it is said that it will support this
10804 in version

10866 <description><p
>The last few days I have been looking into the status of the LDAP
10867 directory in Debian Edu, and in the process I started to miss a GUI
10868 tool to browse the LDAP tree. The only one I was able to find in
10869 Debian/Squeeze and Lenny is
10870 <a href=
"http://luma.sourceforge.net/
">LUMA
</a
>, which has proved to
10871 be a great tool to get a overview of the current LDAP directory
10872 populated by default in Skolelinux. Thanks to it, I have been able to
10873 find empty and obsolete subtrees, misplaced objects and duplicate
10874 objects. It will be installed by default in Debian/Squeeze. If you
10875 are working with LDAP, give it a go. :)
</p
>
10877 <p
>I did notice one problem with it I have not had time to report to
10878 the BTS yet. There is no .desktop file in the package, so the tool do
10879 not show up in the Gnome and KDE menus, but only deep down in in the
10880 Debian submenu in KDE. I hope that can be fixed before Squeeze is
10881 released.
</p
>
10883 <p
>I have not yet been able to get it to modify the tree yet. I would
10884 like to move objects and remove subtrees directly in the GUI, but have
10885 not found a way to do that with LUMA yet. So in the mean time, I use
10886 <a href=
"http://www.lichteblau.com/ldapvi/
">ldapvi
</a
> for that.
</p
>
10888 <p
>If you have tips on other GUI tools for LDAP that might be useful
10889 in Debian Edu, please contact us on debian-edu@lists.debian.org.

29: Ross Reedstrom tipped us about the
10892 <a href=
"http://packages.qa.debian.org/g/gq.html
">gq
</a
> package as a
10893 useful GUI alternative. It seem like a good tool, but is unmaintained
10894 in Debian and got a RC bug keeping it out of Squeeze. Unless that
10895 changes, it will not be an option for Debian Edu based on Squeeze.

10905 <a href=
"http://people.skolelinux.org/pere/blog/Time_for_new__LDAP_schemas_replacing_RFC_2307_.html
">complained
10906 about the fact
</a

10907 for storing DNS and DHCP information in LDAP to combine the two sets
10908 of information into one LDAP object representing a computer.
</p
>
10910 <p
>In the mean time, I discovered that a simple fix would be to make
10911 the dhcpHost object class auxiliary, to allow it to be combined with
10912 the dNSDomain object class, and thus forming one object for one
10913 computer when storing both DHCP and DNS information in LDAP.
</p

10915 <p
>If I understand this correctly, it is not safe to do this change
10916 without also changing the assigned number for the object class, and I
10917 do not know enough about LDAP schema design to do that properly for
10918 Debian Edu.

">testing
10956 of Debian upgrades
</a

've
10957 finally made the upgrade logs available from
10958 <a href=
"http://people.skolelinux.org/pere/debian-upgrade-testing/
">http://people.skolelinux.org/pere/debian-upgrade-testing/
</a
>.
10959 I am now testing dist-upgrade of Gnome and KDE in a chroot using both
10960 apt and aptitude, and found their differences interesting. This time
10961 I will only focus on their removal plans.
</p
>
10963 <p
>After installing a Gnome desktop and the laptop task, apt-get wants
10964 to remove
72 packages when dist-upgrading from Lenny to Squeeze. The
10965 surprising part is that it want to remove xorg and all
10966 xserver-xorg-video* drivers. Clearly not a good choice, but I am not
10967 sure why. When asking aptitude to do the same, it want to remove
129
10968 packages, but most of them are library packages I suspect are no
10969 longer needed. Both of them want to remove bluetooth packages, which
10970 I do not know. Perhaps these bluetooth packages are obsolete?
</p
>
10972 <p
>For KDE, apt-get want to remove
82 packages, among them kdebase
10973 which seem like a bad idea and xorg the same way as with Gnome. Asking
10974 aptitude for the same, it wants to remove
192 packages, none which are
10975 too surprising.
</p
>
10977 <p
>I guess the removal of xorg during upgrades should be investigated
10978 and avoided, and perhaps others as well. Here are the complete list
10979 of planned removals. The complete logs is available from the URL
10980 above. Note if you want to repeat these tests, that the upgrade test
10981 for kde+apt-get hung in the tasksel setup because of dpkg asking
10982 conffile questions. No idea why. I worked around it by using
10983 '<tt
>echo
>> /proc/
<em
>pidofdpkg
</em
>/fd/
0</tt
>' to tell dpkg to
10984 continue.

>The last few days I have done some upgrade testing in Debian, to
11131 see if the upgrade from Lenny to Squeeze will go smoothly. A few bugs
11132 have been discovered and reported in the process
11133 (
<a href=
"http://bugs.debian.org/
585410">#
585410</a
> in nagios3-cgi,
11134 <a href=
"http://bugs.debian.org/

584879</a
> already fixed in
11135 enscript and
<a href=
"http://bugs.debian.org/
584861">#
584861</a
> in
11136 kdebase-workspace-data), and to get a more regular testing going on, I
11137 am working on a script to automate the test.
</p
>
11139 <p
>The idea is to create a Lenny chroot and use tasksel to install a
11140 Gnome or KDE desktop installation inside the chroot before upgrading
11141 it. To ensure no services are started in the chroot, a policy-rc.d
11142 script is inserted. To make sure tasksel believe it is to install a
11143 desktop on a laptop, the tasksel tests are replaced in the chroot
11144 (only acceptable because this is a throw-away chroot).
</p
>
11146 <p
>A naive upgrade from Lenny to Squeeze using aptitude dist-upgrade
11147 currently always fail because udev refuses to upgrade with the kernel
11148 in Lenny, so to avoid that problem the file /etc/udev/kernel-upgrade
11149 is created. The bug report
11150 <a href=
"http://bugs.debian.org/
566000">#
566000</a
> make me suspect
11151 this problem do not trigger in a chroot, but I touch the file anyway
11152 to make sure the upgrade go well. Testing on virtual and real
11153 hardware have failed me because of udev so far, and creating this file
11154 do the trick in such settings anyway. This is a
11155 <a href=
"http://www.linuxquestions.org/questions/debian-
26/failed-dist-upgrade-due-to-udev-config_sysfs_deprecated-nonsense-
804130/
">known
11156 issue
</a
> and the current udev behaviour is intended by the udev
11157 maintainer because he lack the resources to rewrite udev to keep
11158 working with old kernels or something like that. I really wish the
11159 udev upstream would keep udev backwards compatible, to avoid such
11160 upgrade problem, but given that they fail to do so, I guess
11161 documenting the way out of this mess is the best option we got for
11162 Debian Squeeze.

>Som systemarkitekten bak Skolelinux, kan jeg bare riste på hodet
11288 over påstanden om at Skolelinux krever desentraliserte tjenere.
11289 Skolelinux-arkitekturen er laget for sentralisert drift og plassering
11290 av tjenerne lokalt eller sentralt alt etter behov og nettkapasitet.
11291 Den er modellert på nettverks- og tjenerløsningen som brukes på
11292 Universitetet i Tromsø og Oslo, der jeg jobber med utvikling av
11293 driftstjenester. Dette er det heldigvis noen som har fått med seg, og
11294 jeg er glad for å kunne sitere fra en kommentar på den overnevnte
11295 artikkelen. Min venn og gamle kollega Sturle Sunde forteller der:
11298 <p
>I Flora kommune køyrer vi Skulelinux på skular med alt frå
15 til
11299 meir enn
500 elevar. Dei store skulane har eigen tenar, for det er
11300 mest praktisk. Eg, som er driftsansvarleg for heile nettet, ser
11301 sjeldan dei tenarane fysisk, men at dei står der gjer skulane mindre
11302 avhengige av eksterne linjer som er trege eller dyre. Dei minste
11303 skulane har ikkje eigen tenar. Å bruke sentral tenar er heller ikkje
11304 noko problem. Småskulane klarar seg fint med
1 mbit-linje til ein
11305 sentral tenar eller tenaren på ein større skule.
</p
>
11307 <p
>Det beste med Skulelinux er halvtjukke klientar. Dei treng ikkje
11308 harddisk og brukar minimalt med ressursar på tenaren fordi dei køyrer
11309 programma lokalt. Eit klasserom med
30 sju-åtte år gamle maskiner har
11310 mykje meir CPU og RAM totalt enn nokon moderne tenar til under
11311 millionen. Det trengst to kommandoar på den sentrale tenaren for å
11312 oppdatere alle klientane, både tynne og halvtjukke. Vi har ingen
11313 problem med diskar som ryk heller, som var eit problem før fordi
11314 elevane sat og sparka i maskinene. Og dei krev lite bandbreidde i
11315 nettet, so det er fullt mogleg å køyre slike på småskular med trege
11316 linjer mot tenaren på ein større skule.
</p
>
11318 <p
>Flora kommune har nesten
800 Linux-maskiner i sitt skulenett, og
11319 ein person som tek seg av drift av heile nettet, inkludert tenarar,
11320 klientar, operativsystem, programvare, heimekontorløysing og
11321 administrasjon av brukarar.

11323 <p
>No skal det seiast at vi ikkje køyrer rein Skulelinux ut av
11324 boksen. Vi har gjort ein del tilpassingar mot noko Novell-greier som
11325 var der frå før, og som har komplisert installasjonen vår. Etter at

>After a long break from debian-installer development, I finally
11475 found time today to return to the project. Having to spend less time
11476 working dependency based boot in debian, as it is almost complete now,
11477 definitely helped freeing some time.
</p
>
11479 <p
>A while back, I ran into a problem while working on Debian Edu. We
11480 include some firmware packages on the Debian Edu CDs, those needed to
11481 get disk and network controllers working. Without having these
11482 firmware packages available during installation, it is impossible to
11483 install Debian Edu on the given machine, and because our target group
11484 are non-technical people, asking them to provide firmware packages on
11485 an external medium is a support pain. Initially, I expected it to be
11486 enough to include the firmware packages on the CD to get
11487 debian-installer to find and use them. This proved to be wrong.
11488 Next, I hoped it was enough to symlink the relevant firmware packages
11489 to some useful location on the CD (tried /cdrom/ and
11490 /cdrom/firmware/). This also proved to not work, and at this point I
11491 found time to look at the debian-installer code to figure out what was
11492 going to work.
</p
>
11494 <p
>The firmware loading code is in the hw-detect package, and a closer
11495 look revealed that it would only look for firmware packages outside
11496 the installation media, so the CD was never checked for firmware
11497 packages. It would only check USB sticks, floppies and other
11498 "external
" media devices. Today I changed it to also look in the
11499 /cdrom/firmware/ directory on the mounted CD or DVD, which should
11500 solve the problem I ran into with Debian edu. I also changed it to
11501 look in /firmware/, to make sure the installer also find firmware
11502 provided in the initrd when booting the installer via PXE, to allow us
11503 to provide the same feature in the PXE setup included in Debian
11506 <p
>To make sure firmware deb packages with a license questions are not
11507 activated without asking if the license is accepted, I extended
11508 hw-detect to look for preinst scripts in the firmware packages, and
11509 run these before activating the firmware during installation. The
11510 license question is asked using debconf in the preinst, so this should
11511 solve the issue for the firmware packages I have looked at so far.

11536 <p
>This collection of packages allow for two different setups for
11537 roaming laptops. The traditional setup would be using libpam-ccreds,
11538 nscd and libpam-mklocaluser with LDAP or Kerberos authentication,
11539 which should work out of the box if the configuration changes proposed
11540 for nscd in
<a href=
"http://bugs.debian.org/
485282">BTS report
11541 #
485282</a
> is implemented. The alternative setup is to use sssd with
11542 libpam-mklocaluser to connect to LDAP or Kerberos and let sssd take
11543 care of the caching of passwords and group information.
</p
>
11545 <p
>I have so far been unable to get sssd to work with the LDAP server
11546 at the University, but suspect the issue is some SSL/GnuTLS related
11547 problem with the server certificate. I plan to update the Debian
11548 package to version
1.2, which is scheduled for next week, and hope to
11549 find time to make sure the next release will include both the
11550 Debian/Ubuntu specific patches. Upstream is friendly and responsive,
11551 and I am sure we will find a good solution.
</p
>
11553 <p
>The idea is to set up the roaming laptops to authenticate using
11554 LDAP or Kerberos and create a local user with home directory in /home/
11555 when a usre in LDAP logs in via KDM or GDM for the first time, and
11556 cache the password for offline checking, as well as caching group
11557 memberhips and other relevant LDAP information. The
11558 libpam-mklocaluser package was created to make sure the local home
11559 directory is in /home/, instead of /site/server/directory/ which would
11560 be the home directory if pam_mkhomedir was used. To avoid confusion
11561 with support requests and configuration, we do not want local laptops
11562 to have users in a path that is used for the same users home directory
11563 on the home directory servers.
</p
>
11565 <p
>One annoying problem with gdm is that it do not show the PAM
11566 message passed to the user from libpam-mklocaluser when the local user
11567 is created. Instead gdm simply reject the login with some generic
11568 message. The message is shown in kdm, ssh and login, so I guess it is
11569 a bug in gdm. Have not investigated if there is some other message
11570 type that can be used instead to get gdm to also show the message.

11727 <description><p
>For some years now, I have wondered how we should handle laptops in
11728 Debian Edu. The Debian Edu infrastructure is mostly designed to
11729 handle stationary computers, and less suited for computers that come
11732 <p
>Now I finally believe I have an sensible idea on how to adjust
11733 Debian Edu for laptops, by introducing a new profile for them, for
11734 example called Roaming Workstations. Here are my thought on this.
11735 The setup would consist of the following:
</p
>
11739 <li
>During installation, the user name of the owner / primary user of
11740 the laptop is requested and a local home directory is set up for
11741 the user, with uid and gid information fetched from the LDAP
11742 server. This allow the user to work also when offline. The
11743 central home directory can be available in a subdirectory on
11744 request, for example mounted via CIFS. It could be mounted
11745 automatically when a user log in while on the Debian Edu network,
11746 and unmounted when the machine is taken away (network down,
11747 hibernate, etc), it can be set up to do automatic mounting on
11748 request (using autofs), or perhaps some GUI button on the desktop
11749 can be used to access it when needed. Perhaps it is enough to use
11750 the fish protocol in KDE?
</li
>
11752 <li
>Password checking is set up to use LDAP or Kerberos
11753 authentication when the machine is on the Debian Edu network, and
11754 to cache the password for offline checking when the machine unable
11755 to reach the LDAP or Kerberos server. This can be done using
11756 <a href=
"http://www.padl.com/OSS/pam_ccreds.html
">libpam-ccreds
</a
>
11757 or the Fedora developed
11758 <a href=
"https://fedoraproject.org/wiki/Features/SSSD
">System
11759 Security Services Daemon
</a
> packages.
</li
>
11761 <li
>File synchronisation with the central home directory is set up
11762 using a shared directory in both the local and the central home
11763 directory, using unison.
</li
>
11765 <li
>Printing should be set up to print to all printers broadcasting
11766 their existence on the local network, and should then work out of
11767 the box with CUPS. For sites needing accurate printer quotas, some
11768 system with Kerberos authentication or printing via ssh could be
11769 implemented.
</li
>
11771 <li
>For users that should have local root access to their laptop,
11772 sudo should be used to allow this to the local user.
</li
>
11774 <li
>It would be nice if user and group information from LDAP is
11775 cached on the client, but given that there are entries for the
11776 local user and primary group in /etc/, it should not be needed.
</li
>
11780 <p
>I believe all the pieces to implement this are in Debian/testing at
11781 the moment. If we work quickly, we should be able to get this ready
11782 in time for the Squeeze release to freeze. Some of the pieces need
11783 tweaking, like libpam-ccreds should get support for pam-auth-update
11784 (
<a href=
"http://bugs.debian.org/
566718">#
566718</a
>) and nslcd (or
11785 perhaps debian-edu-config) should get some integration code to stop
11786 its daemon when the LDAP server is unavailable to avoid long timeouts
11787 when disconnected from the net. If we get Kerberos enabled, we need
11788 to make sure we avoid long timeouts there too.

11801 NUUG presentation
</a

11802 about the need to start using Kerberos in Skolelinux. Setting up a
11803 Kerberos server seem to be straight forward, and if we get this in
11804 place a long time before the Squeeze version of Debian freezes, we
11805 have a chance to migrate Skolelinux away from NFSv3 for the home
11806 directories, and over to an architecture where the infrastructure do
11807 not have to trust IP addresses and machines, and instead can trust
11808 users and cryptographic keys instead.
</p
>
11810 <p
>A challenge will be integration and administration. Is there a
11811 Kerberos implementation for Debian where one can control the
11812 administration access in Kerberos using LDAP groups? With it, the
11813 school administration will have to maintain access control using flat
11814 files on the main server, which give a huge potential for errors.
</p
>
11816 <p
>A related question I would like to know is how well Kerberos and
11817 pam-ccreds (offline password check) work together. Anyone know?
</p
>
11819 <p
>Next step will be to use Kerberos for access control in Lwat and
11820 Nagios. I have no idea how much work that will be to implement. We
11821 would also need to document how to integrate with Windows AD, as such
11822 shared network will require two Kerberos realms that need to cooperate
11823 to work properly.
</p
>
11825 <p
>I believe a good start would be to start using Kerberos on the
11826 skolelinux.no machines, and this way get ourselves experience with
11827 configuration and integration. A natural starting point would be
11828 setting up ldap.skolelinux.no as the Kerberos server, and migrate the
11829 rest of the machines from PAM via LDAP to PAM via Kerberos one at the
11832 <p
>If you would like to contribute to get this working in Skolelinux,
11833 I recommend you to see the video recording from yesterdays NUUG
11834 presentation, and start using Kerberos at home. The video show show
11835 up in a few days.

11856 <p

11858 after a user. With this framework in place, we finally can do that in
11859 a generic way that work with all display managers using this

11921 the nagios-nrpe-server package installed and configured the way
11922 sitesummary would configure it, are monitored for full disks, software
11923 raid status, swap free and other checks that need to run locally on

11932 is to set the password used to get access via HTTP. The system

11948 Lie, da varamedlem i styret, tok på seg oppdraget om å starte et
11949 initiativ kalt
"Teach the Teacher
", som skulle være et initiativ for
11950 å få fri programvare og unix-lignende operativsystemer inn i Skolen.
11951 Tanken var at en måtte starte med lærerne for at ungene skulle få
11952 mulighet til å møte en bedre IT-hverdag. Jeg var tilstede på
11953 møtet, og hadde sans for ideen, men intet skjedde. På vårparten
11954 2001 ble det arrangert en demonstrasjon i anledning at First Tuesday
11955 hadde invitert Microsoft til et møte for å fortelle om fremtidens
11956 Internet. Dette provoserte endel av oss, og EFN og NUUG tok initiativ

11960 demonstrasjonen var Vidar Bakke fra NUUG og Håkon W. Lie fra EFN.
11961 Etter demonstrasjonen arrangerte Håkon en fest hjemme hos seg der alle
11962 som hadde vært aktive i demonstrasjonsplanlegging og gjennomføringen
11963 deltok. Før festen var jeg blitt lei av å vente på at Håkon skulle ta
11964 initiativ til
"Teach the Teacher
", og for å forsøke å få litt fremgang
11965 besteme jeg meg for å benytte anledningen hos Håkon til å snakke om
11966 behovet for å hjelpe skolene i gang med bedre datasystemer bestående
11967 av fri programvare og unix-lignende operativsystemer. Flere var
11968 interessert, og Knut Yrvin tenkte på ideen. Han

'm sitting on the train going home from this weekends Debian
12006 Edu/Skolelinux development gathering. I got a bit done tuning the
12007 desktop, and looked into the dynamic service location protocol
12008 implementation avahi. It look like it could be useful for us. Almost
12009 30 people participated, and I believe it was a great environment to
12010 get to know the Skolelinux system. Walter Bender, involved in the
12011 development of the Sugar educational platform, presented his stuff and
12012 also helped me improve my OLPC installation. He also showed me that
12013 his Turtle Art application can be used in standalone mode, and we
12014 agreed that I would help getting it packaged for Debian. As a
12015 standalone application it would be great for Debian Edu. We also
12016 tried to get the video conferencing working with two OLPCs, but that
12017 proved to be too hard for us. The application seem to need more work
12018 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
12029 optimal. There is RFC
2307 documenting one way to store NIS maps in
12030 LDAP, and a modified version of this normally called RFC
2307bis, with
12031 some modifications to be compatible with Active Directory. The RFC
12032 specification handle the content of a lot of system databases, but do
12033 not handle DNS zones and DHCP configuration.

12036 we would like to store information about users, SMB clients/hosts,
12037 filegroups, netgroups (users and hosts), DHCP and DNS configuration,
12038 and LTSP configuration in LDAP. These objects have a lot in common,
12039 but with the current LDAP schemas it is not possible to have one
12040 object per entity. For example, one need to have at least three LDAP
12041 objects for a given computer, one with the SMB related stuff, one with
12042 DNS information and another with DHCP information. The schemas
12043 provided for DNS and DHCP are impossible to combine into one LDAP
12044 object. In addition, it is impossible to implement quick queries for
12045 netgroup membership, because of the way NIS triples are implemented.
12046 It just do not scale. I believe it is time for a few RFC
12047 specifications to cleam up this mess.

12092 gjort det umulig å få med ord med bindestrek i

12094 kunne godtas av stavekontrollen. Hadde litt tid til overs å bruke på
12095 stavekontrollen, og satte meg ned med to kopier av byggsystemet og en
12096 liten testdatafil, og byttet ut - med = på utvalgte steder i
12097 byggsystemet og datafilen helt til jeg fikk samme resultat med det
12098 gamle og det nye byggsystemet. Dette tror jeg var forsøk
4, der de
12099 foregående har feilet uten at jeg klarte å forstå hvorfor. Det sier
12100 kanskje litt om kompleksiteten i det originale byggsystemet som Rune

>Recently I have spent some time evaluating the multimedia browser
12142 plugins available in Debian Lenny, to see which one we should use by
12143 default in Debian Edu. We need an embedded video playing plugin with
12144 control buttons to pause or stop the video, and capable of streaming
12145 all the multimedia content available on the web. The test results and
12146 notes are available on
12147 <a href=
"http://wiki.debian.org/DebianEdu/BrowserMultimedia
">the
12148 Debian wiki
</a
>. I was surprised how few of the plugins are able to
12149 fill this need. My personal video player favorite, VLC, has a really
12150 bad plugin which fail on a lot of the test pages. A lot of the MIME
12151 types I would expect to work with any free software player (like
12152 video/ogg), just do not work. And simple formats like the
12153 audio/x-mplegurl format (m3u playlists), just isn
't supported by the
12154 totem and vlc plugins. I hope the situation will improve soon. No
12155 wonder sites use the proprietary Adobe flash to play video.
