>On larger sites, it is useful to use a dedicated storage server for
15 storing user home directories and data. The design for handling this
16 in
<a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>, is
17 to update the automount rules in LDAP and let the automount daemon on
18 the clients take care of the rest. I was reminded about the need to
19 document this better when one of the customers of
20 <a href=
"http://www.slxdrift.no/
">Skolelinux Drift AS
</a
>, where I am
21 on the board of directors, asked about how to do this. The steps to
22 get this working are the following:
</p
>
26 <li
>Add new storage server in DNS. I use nas-server.intern as the
27 example host here.
</li
>
29 <li
>Add automoun LDAP information about this server in LDAP, to allow
30 all clients to automatically mount it on reqeust.
</li
>
32 <li
>Add the relevant entries in tjener.intern:/etc/fstab, because
33 tjener.intern do not use automount to avoid mounting loops.
</li
>
37 <p
>DNS entries are added in GOsa², and not described here. Follow the
38 <a href=
"https://wiki.debian.org/DebianEdu/Documentation/Wheezy/GettingStarted
">instructions
39 in the manual
</a
> (Machine Management with GOsa² in section Getting
42 <p
>Ensure that the NFS export points on the server are exported to the
43 relevant subnets or machines:

>
46 root@tjener:~# showmount -e nas-server
47 Export list for nas-server:

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

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

87 <p
>The last step to remember is to mount the relevant mount points in
88 tjener.intern by adding them to /etc/fstab, creating the mount

91 <p
>When this is done, your users should be able to access the files on

<a href=

104 project
</a
> consist of both newcomers and old timers, and this time I
105 was able to get an interview with a newcomer in the project who showed
106 up on the IRC channel a few weeks ago to let us know about his
107 successful installation of Debian Edu Wheezy in his School. Say hello
108 to
<a href=

113 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
115 <p
>I am a
23 year-old student from Germany who has spent half of his
116 life with open source. In
"real life
", I am, as already mentioned, a
117 student in the fields of Computer Science, Electrical Engineering,
118 Information Technologies and Anglistics. Due to my (only partially
119 voluntary) huge engagement in the open source world, these things are
120 a bit vacant right now however.
</p
>
122 <p
>I also have been working as a project teacher at a Gymasnium
123 (public school) for various years now. I took up that work some time
124 around
2005 when still attending that school myself and have continued
125 it until today. I also had been running the (kind of very advanced)
126 network of that school together with a team of very interested and
127 talented students in the age of
11 to
15 years, who took the chance to
128 learn a lot about open source and networking before I left the school
129 to help building another school
's informational education concept from
132 <p
>That said, one might see me as a kind of
"glue
" between school kids
133 and the elderly of teachers as well as between the open source
134 ecosystem and the (even more complex) educational ecosystem.
</p
>
136 <p
>When I am not busy with open source or education, I like Geocaching
137 and cycling.
</p
>
139 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
140 project?
</strong
></p
>
142 <p
>I think that happened some time around
2009 when I first attended
143 <a href=
"http://www.froscon.org
">FrOSCon
</a
> and visited the project
144 booth. I think I wasn
't too interested back then because I used to
145 have an attitude of disliking software that does too much stuff on its
146 own. Maybe I was too inexperienced to realise the upsides of an
147 "out-of-the-box
" solution ;).
</p
>
149 <p
>The first time I actively talked to Skolelinux people was at
150 <a href=
"http://www.openrheinruhr.de
">OpenRheinRuhr
</a
> 2011 when the
151 BiscuIT project, a home-grewn software used by my school for various
152 really cool things from timetables and class contact lists to lunch
153 ordering, student ID card printing and project elections first got to
154 a stage where it could have been published. I asked the Skolelinux
155 guys running the booth if the project were interested in it and gave a
156 small demonstration, but there wasn
't any real feedback and the guys
157 seemed rather uninterested.
</p
>
159 <p
>After I left the school where I developed the software, it got
160 mostly lost, but I am now reimplementing it for my new school. I have
161 reusability and compatibility in mind, and I hop there will be a new
162 basis for contributing it to the Skolelinux project ;)!
</p
>
164 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
165 Edu?
</strong
></p
>
167 <p
>The most important advantage seems to be that it
"just
168 works
". After overcoming some minor (but still very annoying) glitches
169 in the installer, I got a fully functional, working school network,
170 without the month-long hassle I experienced when setting all that up
171 from scratch in earlier years. And above that, it rocked - I didn
't
172 have any real hardware at hand, because the school was just founded
173 and has no money whatsoever, so I installed a combined server (main
174 server, terminal services and workstation) in a VM on my personal
175 notebook, bridging the LTSP network interface to the ethernet port,
176 and then PXE-booted the Windows notebooks that were lying around from
177 it. I could use
8 clients without any performance issues, by using a
178 tiny little VM on a tiny little notebook. I think that
's enough to say
179 that it rocks!
</p
>
181 <p
>Secondly, there are marketing reasons. Life
's bad, and so no
182 politician will ever permit a setup described as
"Debian, an universal
183 operating system, with some really cool educational tools
" while they
184 will be jsut fine with
"Skolelinux, a single-purpose solution for your
185 school network
", even if both turn out to be the very same thing (yes,
186 this is unfair towards the Skolelinux project, and must not be taken
187 too seriously - you get the idea, anyway).
</p
>
189 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
190 Edu?
</strong
></p
>
192 <p
>I have not been involved with Skolelinux long enough to really
193 answer this question in a fair way. Thus, please allow me to put it in
194 other words:
"What do you expect from Skolelinux to keep liking it?
" I
195 can list a few points about that:
</p
>
199 <li
>always strive to get all things integrated into Debian upstream
200 <li
>be open to discussion about changes and the like, even with newcomers
201 <li
>be helpful at being helpful ;)
205 <p
>I
'm really sorry I cannot say much more about that :(!
</p
>
207 <p
><strong
>Which free software do you use daily?
</strong
></p
>
209 <p
>First of all, all software I use is free and open. I have abandoned
210 all non-free software (except for firmware on my darned phone) this
213 <p
>I run Debian GNU/Linux on all PC systems I use. On that, I mostly
214 run text tools. I use
215 <a href=
"https://www.mirbsd.org/mksh.htm
">mksh
</a
> as shell,
216 <a href=
"https://www.mirbsd.org/jupp.htm
">jupp
</a
> as very advanced
217 text editor (I even got the developer to help me write a script/macro
218 based full-featured student management software with the two),
219 <a href=
"http://mcabber.com/
">mcabber
</a
> for XMPP and
220 <a href=
"http://www.irssi.org/
">irssi
</a
> for IRC. For that overly
221 coloured world called the WWW, I use
222 <a href=
"https://www.mozilla.org/en-US/firefox/new/
">Iceweasel
223 (Firefox)
</a
>. Oh, and
<a href=
"http://www.mutt.org/
">mutt
</a
> for
226 <p
>However, while I am personally aware of the fact that text tools
227 are more efficient and powerful than anything else, I also use (or at
228 least operate) some tools that are suitable to bring open source to
229 kids. One of these things is
<a href=
"http://jappix.org/
">Jappix
</a
>,
230 which I already introduced to some kids even before they got aware of
231 Facebook, making them see for themselves that they do not need
232 Facebook now ;).
</p
>
234 <p
><strong
>Which strategy do you believe is the right one to use to
235 get schools to use free software?
</strong
></p
>
237 <p
>Well, that
's a two-sided thing. One side is what I believe, and one
238 side is what I have experienced.
</p
>
240 <p
>I believe that the right strategy is showing them the benefits. But
241 that won
't work out as long as the acceptance of free alternatives
242 grows globally. What I mean is that if all the kids are almost forced
243 to use Windows, Facebook, Skype, you name it at home, they will not
244 see why they would want to use alternatives at school. I have seen
245 students take seat in front of a fully-functional, modern Debian
246 desktop that could do anything their Windows at home could do, and
247 they jsut refused to use it because
"Linux sucks
". It is something
248 that makes the council of our city spend around
600000 € to buy
249 software - not including hardware, mind you - for operating school
250 networks, and for installing a system that, as has been proved, does
251 not work. For those of you readers who are good at maths, have you
252 already found out how many lives could have been saved with that money
253 if we had instead used it to bring education to parts of the world
254 that need it? I have, and found it to be nothing less dramatic than
255 plain criminal.
</p
>
257 <p
>That said, the only feasible way appears to be the bottom up
258 method. We have to bring free software to kids and parents. I have
259 founded an association named
260 <a href=
"https://www.teckids.org
">Teckids
</a
> here in Germany that does
261 just that. We organise several events for kids and adolescents in the
262 area of free and open source software, for example the
263 <a href=
"http://kids.froscon.org
">FrogLabs
</a
>, which share staff with
264 Teckids and are the youth programme of
265 <a href=
"http://www.froscon.org
">the Free and Open Source Software
266 Conference (FrOSCon)
</a
>. We do a lot more than most other conferences
267 - this year, we first offered the FrogLabs as a holiday camp for kids
268 aged
10 to
16. It was a huge success, with approx.
30 kids taking part
269 and learning with and about free software through a whole weekend. All
270 of us had a lot of fun, and the results were really exciting.
</p
>
272 <p
>Apart from that, we are preparing a campaign that is supposed to bring
273 the message of free alternatives to stuff kids use every day to them and
274 their parents, e.g. the use of Jabber / Jappix instead of Facebook and
275 Skype. To make that possible, we are planning to get together a team of
276 clever kids who understand very well what their peers need and can bring
277 it across to them. So we will have a peer-driven network of adolescents
278 who teach each other and collect feedback from the community of minors.
279 We then take that feedback and our own experience to work closely with
280 open source projects, such as Skolelinux or Jappix, at improving their
281 software in a way that makes it more and more attractive for the target
282 group. At least I hope that we will have good cooperation with
283 Skolelinux in the future ;)!
</p
>
285 <p
>So in conclusion, what I believe is that, if it weren
't for the world
286 being so bad, it should be very clear to the political decision makers
287 that the only way to go nowadays is free software for various reasons,
288 but I have learnt that the only way that seems to work is bottom up.
</p
>
292 > * Who should be interviewed with this questions in the future?
294 That
's probably the hardest question of them all, as I do not know the
295 community. However, I would be willing to do the following:
297 <li
>Run an interview with a German headteacher who is very open to
298 free software, and also prefers it, but cannot really use it because
299 of the decision makers above;
300 <li
>Run interviews with some kids, both with and without previous
301 knowledge about free software
303 If that is wanted, just let me know ;).

366 <li
>Skolelinux is - as we had to learn - not easily upgradable to
367 the next version. Opposed to its genuine Debian base, upgrading to
368 a new version means a full new installation from scratch to get it
369 working again reliably.
371 <li
>Skolelinux is based on Debian/stable, and therefore always a
372 little outdated in terms of program versions compared to Edubuntu or
373 similar educational Linux distros, which rather use Debian/testing
376 <li
>Skolelinux has some very self-opinionated and stubborn default
377 configuration which in my opinion adds unnecessary complexity and is
378 not always suitable for a schools needs, the preset network
379 configuration is actually a core definition feature of Skolelinux
380 and not easy to change, so schools sometimes have to change their
381 network configuration to make it
"Skolelinux-compatible
".
383 <li
>Some proposed extensions, which were made available as
384 contribution, like secure examination mode and lecture material
385 distribution and collection, were not accepted into the mainline
386 Skolelinux development and are now not easy to maintain in the
387 future because of Skolelinux somewhat undeterministic update
390 <li
>Skolelinux has only a very tiny number of base developers
391 compared to Debian.
</li

395 <p
>For these reasons and experience from our project, I would now
396 rather consider using plain Debian for schools next time, until

443 on laptops that should not be integrated into the provided network
444 services (no central home directory, no Kerberos / LDAP directory etc,

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

474 section

</p

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

559 <p
>Debian Edu, also known as Skolelinux, is a Linux distribution based
560 on Debian providing an out-of-the box environment of a completely
561 configured school network. Immediately after installation a school
562 server running all services needed for a school network is set up just
563 waiting for users and machines being added via GOsa², a comfortable
564 Web-UI. A netbooting environment is prepared using PXE, so after
565 initial installation of the main server from CD or USB stick all other
566 machines can be installed via the network. The provided school server
567 provides LDAP database and Kerberos authentication service,
568 centralized home directories, DHCP server, web proxy and many other
569 services. The desktop contains more than
60 educational software
570 packages and more are available from the Debian archive, and schools
571 can choose between KDE, Gnome, LXDE and Xfce desktop environment.

574 this is an updated and slightly improved version compared to the
575 Squeeze release.

577 <p
>Notes for upgrades from Alpha Prereleases
</p
>
579 <p
>Alpha based installations should reinstall or downgrade the
580 versions of gosa and libpam-mklocaluser to the ones used in this beta
581 release. Both alpha and beta0 based installations should reinstall or
582 deal with gosa.conf manually; there are two options: (
1) Keep
583 gosa.conf and edit this file as outlined on the mailing list. (
2)
584 Accept the new version of gosa.conf and replace both contained admin
585 password placeholders with the password hashes found in the old one
586 (backup copy!). In both cases all users need to change their password
587 to make sure a password is set for CIFS access to their home

">Debian Edu, also known as
900 Skolelinux
</a
>, is a Linux distribution based on Debian providing an
901 out-of-the box environment of a completely configured school
902 network. Immediately after installation a school server running all
903 services needed for a school network is set up just waiting for users
904 and machines being added via GOsa², a comfortable Web-UI. A netbooting
905 environment is prepared using PXE, so after initial installation of
906 the main server from CD, DVD or USB stick all other machines can be
907 installed via the network. The provided school server provides LDAP
908 database and Kerberos authentication service, centralized home
909 directories, DHCP server, web proxy and many other services. The
911 <a href=
"http://people.skolelinux.org/pere/blog/Educational_applications_included_in_Debian_Edu___Skolelinux__the_screenshot_collection____.html
">more
912 than
60 educational software packages
</a
> and more are available from
913 the Debian archive, and schools can choose between KDE, Gnome, LXDE
914 and Xfce desktop environment.
</p
>
916 <p
>This is the fourth test release based on Debian Wheezy. Basically
917 this is an updated and slightly improved version compared to the
918 Squeeze release.
</p
>
920 <p
><strong
>Software updates
</strong
></p
>
922 <li
>Dropped ispell dictionaries from our default installation.
</li
>
923 <li
>Dropped menu-xdg from the KDE desktop option, to drop the Debian
924 submenu. It was not included with Gnome, LXDE or Xfce, so this
925 brings KDE in line with the others.
</li
>
926 <li
>Dropped xdrawchem, xjig and xsok from our default installation as
927 they don
't have a desktop menu entry and thus won
't show up in the
928 menu now that menu-xdg was removed.
</li
>
929 <li
>Removed the killer system to kill left behind processes on
930 multi-user machines, as it was no longer able to understand when a
931 X display was in use and killed the processes of the active users
933 <li
>Dropped the golearn (from goplay) package as the debtags in wheezy
934 are too few to make the package useful.
</li
>
936 <p
><strong
>Other changes
</strong
></p
>
938 <li
>Updated artwork matching http://wiki.debian.org/DebianArt/Themes/Joy
939 <li
>Multi-arch i386/amd64 USB stick ISO available.
</li
>
940 <li
>Got rid of ispell/wordlist related debconf questions that showed
941 up for some language options.
</li
>
942 <li
>Switched to using http.debian.net as APT source by default.
</li
>
943 <li
>Fixed proxy configuration on Main Server installations.
</li
>
944 <li
>Changed LTSP setup to ask dpkg to use force-unsafe-io the same way
945 d-i is doing it.
</li
>
946 <li
>Made sure root and user passwords were not left behind in the
947 debconf database after installation on Main Server installations.
</li
>
948 <li
>Made Roaming Workstation dynamic setup more robust and added draft
949 script setup-ad-client to hook a Roaming Workstation up to a
950 Active Directory server instead of a Debian Edu Main Server.
</li
>
951 <li
>Update system to install needed firmware packages during
952 installation, to work properly in Wheezy.
</li
>
953 <li
>Update system to handle hardware quirks (debian-edu-hwsetup).
</li
>
954 <li
>Corrected PXE installation setup to properly pass selected desktop
955 and keymap settings to PXE installation clients.
</li
>
956 <li
>LTSP diskless workstations use sshfs by default, allowing them to
957 work without adding them to DNS and NIS netgroups for NFS access.

>In the
<a href=
"http://www.skolelinux.org/
">Debian Edu /
999 Skolelinux
</a
> project, we include a post-installation test suite,
1000 which check that services are running, working, and return the
1001 expected results. It runs automatically just after the first boot on
1002 test installations (using test ISOs), but not on production
1003 installations (using non-test ISOs). It test that the LDAP service is
1004 operating, Kerberos is responding, DNS is replying, file systems are
1005 online resizable, etc, etc. And it check that the PXE service is
1006 configured, which is the topic of this post.
</p
>
1008 <p
>The last week I
've fixed the DVD and USB stick ISOs for our Debian
1009 Edu Wheezy release. These ISOs are supposed to be able to install a
1010 complete system without any Internet connection, but for that to
1011 happen all the needed packages need to be on them. Thanks to our test
1012 suite, I discovered that we had forgotten to adjust our PXE setup to
1013 cope with the new names and paths used by the netboot d-i packages.
1014 When Internet connectivity was available, the installer fall back to
1015 using wget to fetch d-i boot images, but when offline it require
1016 working packages to get it working. And the packages changed name
1017 from debian-installer-
6.0-netboot-$arch to
1018 debian-installer-
7.0-netboot-$arch, we no longer pulled in the
1019 packages during installation. Without our test suite, I suspect we
1020 would never have discovered this before release. Now it is fixed
1021 right after we got the ISOs operational.
</p
>
1023 <p
>Another by-product of the test suite is that we can ask system
1024 administrators with problems getting Debian Edu to work, to run the
1025 test suite using
<tt
>/usr/sbin/debian-edu-test-install
</tt
> and see if
1026 any errors are detected. This usually pinpoint the subsystem causing
1027 the problem.

>The
<a href=
"http://www.skolelinux.org/

1045 globe. And a while back, an enterprising young man showed up on
1046 <a href=
"irc://irc.debian.org/%

">our IRC channel
1047 #debian-edu
</a

1048 worked. We answered as good as we could, and even convinced him to
1049 help us with translations. And today I managed to get an interview
1050 with him, to learn more about him.

</strong

1054 <p
>I
'm a
25 year old free software enthusiast, living in Romania,
1055 which is also my country of origin. Back in
2009, at a New Year
's Eve
1056 party, I had a very nice
<strike
>beer
</strike
> discussion with a
1057 friend, when we realized we have no organised Debian community in our
1058 country. A few days later, we put together the infrastructure for such
1059 community and even gathered a nice Debian-ish crowd. Since then, I
1060 began my quest as a free software hacker and activist and I am
1061 constantly trying to cover as much ground as possible on that
1064 <p
>A few years ago I founded a small web development company, which
1065 provided me the flexible schedule I needed so much for my
1066 activities. For the last
13 months, I have been the Technical Director
1067 of
<a href=
"http://ceata.org/
">Fundația Ceata
</a
>, which is a free
1068 software activist organisation endorsed by the FSF and the FSFE, and
1069 the only one we have in our country.
</p
>
1071 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
1072 project?
</strong
></p
>
1074 <p
>The idea of participating in the Debian Edu project was a surprise
1075 even to me, since I never used it before I began getting involved in
1076 it. This year I had a great opportunity to deliver a talk on
1077 educational software, and I knew immediately where to look. It was a
1078 love at first sight, since I was previously involved with some of the
1079 technologies the project incorporates, and I rapidly found a lot of
1080 ways to contribute.
</p
>
1082 <p
>My first contributions consisted in translating the installer and
1083 configuration dialogs, then I found some bugs to squash (I still
1084 haven
't fixed them yet though), and I even got my eyes on some other
1085 areas where I can prove myself helpful. Since the appetite for free
1086 software in my country is pretty low, I
'll be happy to be the first
1087 one around here advocating for the project
's adoption in educational
1088 environments, and maybe even get my hands dirty in creating a flavour
1089 for our own needs. I am not used to make very advanced plannings, so
1090 from now on, time will tell what I
'll be doing next, but I think I
1091 have a pretty consistent starting point.
</p

1093 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
1094 Edu?
</strong
></p
>
1096 <p
>Not a long time ago, I was in the position of configuring and
1097 maintaining a LDAP server on some Debian derivative, and I must say it
1098 took me a while. A long time ago, I was maintaining a bigger
1099 Samba-powered infrastructure, and I must say I spent quite a lot of
1100 time on it. I have similar stories about many of the services included
1101 with Skolelinux, and the main advantage I see about it is the
1102 out-of-the box availability of them, making it quite competitive when
1103 it comes to managing a school
's network, for example.
</p
>
1105 <p
>Of course, there is more to say about Skolelinux than the
1106 availability of the software included, its flexibility in various
1107 scenarios is something I can
't wait to experiment
"into the wild
" (I
1108 only played with virtual machines so far). And I am sure there is a
1109 lot more I haven
't discovered yet about it, being so new within the

><strong
>What do you see as the disadvantages of Skolelinux / Debian
1113 Edu?
</strong
></p
>
1115 <p
>As usual, when it comes to Debian Blends, I see as the biggest
1116 disadvantage the lack of a numerous team dedicated to the
1117 project. Every day I see the same names in the changelogs, and I have
1118 a constantly fear of the bus factor in this story. I
'd like to see
1119 Debian Edu advertised more as an entry point into the Debian
1120 ecosystem, especially amongst newcomers and students. IMHO there are a
1121 lot low-hanging fruits in terms of bug squashing, and enough
1122 opportunities to get the feeling of the Debian Project
's dynamics. Not
1123 to mention it
's a very fun blend to work on!
</p
>
1125 <p
>Derived from the previous statement, is the delay in catching up
1126 with the main Debian release and documentation. This is common though
1127 to all blends and derivatives, but it
's an issue we can all work
1130 <p
><strong
>Which free software do you use daily?
</strong
></p
>
1132 <p
>I can hardly imagine myself spending a day without Vim, since my
1133 daily routine covers writing code and hacking configuration files. I
1134 am a fan of the Awesome window manager (but I also like the
1135 Enlightenment project a lot!),
1136 <a href=
"http://www.claws-mail.org/

1137 use and very configurable behaviour. Recently I fell in love with
1138 <a href=
"https://launchpad.net/redshift

1139 get through the night without headaches. Of course, there is much more
1140 stuff in this bag, but I
'll need a blog on my own for doing this!

1143 get schools to use free software?
</strong

1145 <p
>Well, on this field, I cannot do much more than experiment right
1146 now. So, being far from having a recipe for success, I can only assume
1151 <li
>schools would like to get rid of proprietary software
</li
>
1153 <li
>students will love the openness of the system, and will want to
1154 experiment with it - maybe we need to harvest the native curiosity
1155 of teenagers more?
</li
>
1157 <li
>there is no
"right one
" when it comes to strategies, but it would
1158 be useful to have some success stories published somewhere, so
1159 other can get some inspiration from them (I know I
'd promote
1162 <li
>more active promotion - talks, conferences, even small school
1163 lectures can do magical things if they encounter at least one
1164 person interested. Who knows who that person might be? ;-)
</li
>
1168 <p
>I also see some problems in getting Skolelinux into schools; for
1169 example, in our country we have a great deal of corruption issues, so
1170 it might be hard(er) to fight against proprietary solutions. Also,
1171 people who relied on commercial software for all their lives, would be
1172 very hard to convert against their will.

've been somewhat familiar with the project before, but I think my

1203 [Reinholdtsen] and Knut [Yrvin] at the Edubuntu summit in
2005 in
1204 London. They provided great feedback that helped the bootstrapping of
1205 Edubuntu. Back then Edubuntu (and even Ubuntu) was still very new and
1206 it was great getting input from people who have been around longer. I
1207 was also still very excitable and said yes to everything and to this
1208 day I have a big todo list backlog that I
'm catching up with. I think
1209 over the years the relationship between Edubuntu and Debian-Edu has
1210 been gradually improving, although I think there

1222 <p

1235 <p
>The biggest disadvantage I can think of is lack of manpower. The
1236 project could do so much more if there were more good contributors. I
1237 think some of the problems are external too. Free software and free
1238 content in education is a no-brainer but it takes some time to catch
1239 on. When you
've been working with the same proprietary eco-system for
1240 years and have gotten used to it, it can be hard to adjust to some
1241 concepts in the free software world. It would be nice if there were
1242 more Debian Edu consultants across the world. I
'd love to be one
1243 myself but I
'm already so over-committed that it
's just not possible
1244 currently.
</p

1246 <p
>I think the best short-term solution to that large-scale problem is
1247 for schools to be pro-active and share their experiences and grow
1248 their skills in-house. I
'm often saddened to see how much money
1249 educational institutions spend on
3rd party solutions that they don
't
1250 have access to after the service has ended and they could
've gotten so
1251 much more value otherwise by being more self-sustainable and
1252 autonomous.

1257 Windows free for years but started dual-booting again last year for
1258 some games which help me focus and relax (Starcraft II in

'm taking some refuge in Xfce
1265 while I figure that out. I like tools that keep things simple. I enjoy

">Debian Edu, also known as
1319 Skolelinux
</a
>, is a Linux distribution based on Debian providing an
1320 out-of-the box environment of a completely configured school
1321 network. Immediately after installation a school server running all
1322 services needed for a school network is set up just waiting for users
1323 and machines being added via GOsa², a comfortable Web-UI. A netbooting
1324 environment is prepared using PXE, so after initial installation of
1325 the main server from CD, DVD or USB stick all other machines can be
1326 installed via the network. The provided school server provides LDAP
1327 database and Kerberos authentication service, centralized home
1328 directories, DHCP server, web proxy and many other services. The

1522 <p

1524 not have all the elements to evaluate properly free software
1525 solutions. The fact that support by a company may be difficult to find
1526 is probably a problem if the school does not have IT personnel.

1528 <p

1531 companies providing support for Debian Edu, like Germany or
1532 Norway. This list is easy to find readily from the manual. However,
1533 for other countries, like France, the list is empty. I guess that
1534 consultants proposing support for Debian would be able to provide some
1535 support for Debian Edu as well.

1750 <p
>Jeg heter Nirosan Thiyagalingam. Jeg er
24 år og studerer
1751 dataingeniør studiet ved Høgskolen i Sør Trøndelag. Interessen for
1752 data har siden ung alder vært tilstede og jeg har i tillegg alltid
1753 vært glad i å lære nye ting. Med teknologi som endres svært hurtig er
1754 det alltid noe nytt å lære. Noe som igjen har gjort det svært
1755 interessant å følge med på utviklingen. Jeg valgte dataingeniør
1756 studiet grunnet ønske om å lære enda mer om programmering og utvikling
1757 av store systemer.
</p
>
1759 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
1761 <p
>Skolelinux prosjektet hørte jeg først om i media. Men det var først
1762 når jeg skulle velge bacheloroppgave at jeg fattet mer interesse for
1763 prosjektet. Et enkelt søk på nettet førte meg til skolelinux sine
1764 hjemmesider. Informasjonen jeg fant der gjorde meg enda nysgjerrig og
1765 jeg valgte derfor en oppgave som gikk ut på å få en
1766 <a href=
"http://www.raspberrypi.org
">Raspberry PI
</a
>. Altså en
1767 ultra-billig datamaskin til å kjøre Debian Edu på lik linje med
1768 vanlige datamaskiner. I løpet av prosjektet ble det gjort mye
1769 forskning på nettet. Det var mye jeg måtte forstå rundt hvordan
1770 operativsystemet Linux fungerte før jeg kunne angripe
1771 problemet. Prøvde først å finne ut hvordan man kunne transformere en
1772 vanlig installasjon av Skolelinux til Raspberry PI, men dette var
1773 altfor vanskelig å jeg endte opp med mer spørsmål enn svar. Det ble
1774 videre opprettet kontakt med Skolelinux utviklere på IRC der jeg fikk
1775 diskutert hvilken retning jeg burde gå for å få til en fullverdig
1776 løsning. Det ble bestemt at jeg skulle gå for å først installere
1777 <a href=
"http://www.raspbian.org/
">Raspian
</a
>. Dette er et
1778 operativsystem basert på Debian spesiallaget for Raspberry Pi sin
1779 maskinvare. Nå som Debian var installert på datamaskinen gjenstod det
1780 å installere de nødvendige Skolelinux pakkene for å få til et
1781 fullverdig system. Disse pakkene ble installert manuelt i første
1782 omgang, men ble senere installert automatisk via et script som Petter
1783 Reinholdtsen laget. Dette scriptet er så enkel å bruke at man er i
1784 gang med installasjonen i løpet av bare
5 minutter. Ikke nok med det,
1785 alt skjer helt automatisk. Alt i alt er jeg veldig fornøyd med
1786 resultatet av installasjonsprosessen. Raspberry Pi er en veldig svak
1787 maskin og det merkes godt når man har installert Skolelinux på
1788 den. Video og
3D-rendering fungerer utrolig dårlig, men nettsurfing og
1789 kontorprogrammer fungerer godt. Det kan derfor konkluderes med at
1790 datamaskinen er egnet for enkle oppgaver.
1792 <p
>Jeg syns det er viktig påpeke at dette kun er startfasen av en slik
1793 løsning. På markedet finnes det nå maskiner som har bedre hardware enn
1794 Raspberry Pi. Det er store muligheter for at man kan klare å
1795 installere Skolelinux på disse også, og da forsvinner nok mest
1796 sannsynlig ytelsesproblemene med Video og
3D rendering også.
</p
>
1798 <p
>Det ble også prøvd med en løsning som gjorde at Raspberry Pi
1799 fungerte som en tynnklient. Denne løsningen hadde langt bedre ytelse
1800 med tanke på hastighet og brukeropplevelse. Men også her var video og
1801 3D rendering dårlig. Det ble brukt en liten Linux distribusjon kalt
1802 <a href=

">BerryTerminal
</a
> for å få til
1805 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
1807 <p
>Fordelen med Skolelinux er mange. At det er gratis er en stor
1808 fordel, men at det er så mange som er med på å utvikle det og
1809 vedlikeholde det er en enda større fordel. Allerede før jeg startet
1810 med prosjektet så jeg mange fordeler, og når jeg nærmet meg sluttfasen
1811 så jeg langt flere. At prosjektet skulle inneha en så høy kvalitet
1812 hadde jeg aldri trodd. En vanlig Skolelinux installasjon har de
1813 nødvendige programmene og funksjonen som både små og store skoler i
1814 tillegg til organisasjoner kan klare seg med. At prosjektet tilbyr en
1815 så komplett løsning er en kjempefordel. Installasjonen er knirkefri
1816 og det er svært enkelt å installere og komme i gang.
</p
>
1818 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
1820 <p
>Ulempene jeg ser med prosjektet er ryddigheten av websidene. Selv
1821 om websidene er enkle og konsise er det allikevel ikke appellerende i
1822 like stor grad som for eksempel
1823 <a href=
"http://www.ubuntu.com
">Ubuntu
</a
> sine sider. Deres side
1824 tilbyr, i tillegg til godt design og presentasjon, en nettbasert
1825 emulator av deres operativsystem. Dette er en stor fordel slik jeg ser
1826 det. Bortsett fra dette ser jeg absolutt ingen ulemper med
1827 Skolelinux-prosjektet.
</p

1829 <p
><strong
>Hvilken fri programvare bruker du til daglig?

1831 <p
>Til daglig er jeg en flittig bruker av det åpne media
1832 sentersystemet
<a href=
"http://xbmc.org/
">XBMC
</a
>. Det enorme
1833 samfunnet rundt dette prosjektet har gjort dette til et program som
1834 dekker alles behov. Man kan tilpasse det akkurat slik man vil både med
1835 tanke på utseende og funksjoner ved installere plug-ins eller
1838 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
1839 skoler til å ta i bruk fri programvare?
</strong
></p
>
1841 <p
>Strategien som burde brukes sett fra mine øyne er
1842 markedsføring. Jeg er sikker på at om flere skoler fikk et lite innsyn
1843 i hvor bra Skolelinux er så ville de ikke nølt med å gå over fra noe
1844 annet som koster de store summer. At skolelinux til de grader tilbyr
1845 en så komplett løsning bure komme frem. Enten via reklamekampanjer
1846 eller ved å sende ut folk til skoler for så å la skolenettverk
1847 ansvarlige få teste ut hvordan Skolelinux fungerer i praksis. Om det
1848 i tillegg ble utviklet gode websider og en emulator for å la brukere
1849 prøve operativsystemet ville nok dette ha styrket inntrykket
1850 betraktelig.

1944 <p
>Debian Edu, also known as Skolelinux, is a Linux distribution based
1945 on Debian providing an out-of-the box environment of a completely
1946 configured school network. Immediatly after installation a school
1947 server running all services needed for a school network is set up just
1948 waiting for users and machines being added via GOsa², a comfortable
1949 Web-UI. A netbooting environment is prepared using PXE, so after
1950 initial installation of the main server from CD, DVD or USB stick all
1951 other machines can be installed via the network.

2105 out-of-the box environment of a completely configured school
2106 network. Immediatly after installation a school server running all
2107 services needed for a school network is set up just waiting for users
2108 and machines being added via GOsa², a comfortable Web-UI. A netbooting
2109 environment is prepared using PXE, so after initial installation of
2110 the main server from CD, DVD or USB stick all other machines can be
2111 installed via the network.

6. He installed the standalone profile and
2237 the video show a walk-through of of the menu content, demonstration of
2238 a few programs and his view of our distribution.
</p
>
2240 <p
>There is also some really nice quotes (transcribed by me, might
2241 have heard wrong). While looking thought the Graphics menu:
</p
>
2244 "Basically everything you ever need in a school environment.
"
2247 <p
>And as a general evaluation of the entire distribution:
</p
>
2250 "So, yeah, a bit bloated. It kept all the Debian stuff in there, just
2251 to keep it nice and GNU. So, I do not want to go on about it, but
2252 lets give it
7 out of
10. I am not going to use it. That is because
2253 I am not deploying a school network. There may be some mythical
2254 feature to help you deploy Skolelinux on a school network.
"
2257 <p
>To bad he did not test the server profile, and discovered the PXE
2258 installation option. It make it possible to install only the main
2259 server from CD, and the rest of the machines via the net, and might be
2260 considered the mythical feature he talk about. :)
</p
>
2262 <p
>While looking through the menus, there is also this funny comment
2263 about the part of the K menu generated from the Debian menu subsystem:
2266 "[The K menu] have a special Debian section for software that no-one
2267 is going to look at, because it contain lots of junky stuff that you
2268 actually don
't need in the education distribution, but have just been
2269 included because it isn
't stripped out for some reason.
"
2272 <p
>I guess it is yet another argument for merging the Debian menu and
2273 Gnome/KDE desktop menu entries into
2274 <a href=
"http://wiki.debian.org/Proposals/DebianMenuUsingDesktopEntries
">one
2275 consistent menu system
</a
> instead of two incomplete and partly
2276 inconsistent menu systems.

2411 <p
>Eg kom i kontakt med Skolelinux-prosjektet via ein artikkel i eit
2412 fagblad, som eg ikkje lenger hugsar namnet på. I og med at eg allereie
2413 hadde pusla med nettverk for ein annan skule, fatta eg straks
2414 interesse for prosjektet.

2416 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
2418 <p
>Fordelane med Skolelinux er sentralisert administrasjon og svært
2419 mange gode verktøy «ut av boksen». Veldig kjekt å kunne drifte
60
2420 klientar med berre å «bry» seg med ein server. Levetid for systemets
2421 hardware er og ein veldig fin effekt. I tillegg kjem fordelar som økt
2422 sikkerhet og mindre lisenskostnader. Etter min erfaring er det og
2423 mykje mindre driftskostnader med eit slikt system enn konkurrerande
2424 system, pga enkelhet med sentralisert administrasjon. På grunn av at
2425 Skolelinux er basert på Debian er det òg svært stabilt.
</p
>
2427 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
2429 <p
>Ulemper er mangel på vilje til å følge standarer ute i markedet,
2430 som fører til mangel på støtte til nokre mykje brukte ting. Flash og
2431 Java er typiske eksempel. Sidan Debian satsar på stabilitet framfor å
2432 ha nyeste pakke av eit program, kan ein i nokre tilfeller kome borti
2433 at program vert «for gamle». Det er spesielt nettlesaren som er
2434 utsett. Mangel på vilje til å utvikle pedagogisk programvare, i Noreg,
2435 for «alle» platformer fører òg til noko hovudbry.
</p
>
2437 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
2439 <p
>Til dagleg bruker eg svært mange forskjellige «fri programvare»
2440 program. Firefox, Thunderbird, Freecommander, ImgBurn, Clonezilla,
2441 OCS inventory, Icinga, Skolelinux, SystemRescueCD og mykje meir.
</p
>
2443 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
2444 skoler til å ta i bruk fri programvare?
</strong
></p
>
2446 <p
>Strategisk må ein fokusere på at sluttbruker eigentleg ikkje er så
2447 fokusert på at det er fri programvare men at det skal «berre fungere».
2448 Gjer det enkelt å bruker og ikkje minst å administrere. For Skolelinux
2449 sin del må ein få eit betre fokus på overganger. Utbytting av servere
2450 må gå meir automatisk, import og eksport av brukerbase og maskinbase
2451 med meir må kunne gå enkelt og oppgradering til neste versjon må bli
2452 mykje meir automatisk og gjennomtesta. Ein må unngå at ein må sette
2453 opp frå start når ein byter ut ein server eller oppgraderer til neste
2454 versjon. For å få Skolelinux til å bli eit betre alternativ for skular
2455 må ein ha fokus på nettlesaren. Denne må bli «up to date» og støtte
2456 dei protokollar og tillegg som vert brukt av forlag med meir. Etter
2457 kvart som meir og meir blir flytta ut i «skya» vert dette viktigare og
2458 viktigare. Ein kunne ynskje og jobbe for at forlag med fleire tar i
2459 bruk opne standarer, men inntil det skjer, må systemet kunne brukast
2460 mot desse fagsystema.
</p
>
2462 <p
>For meg har prosjektet med Skolelinux vore ein svært artig og
2463 lærerik prosess. Miljøet rundt er ikkje enormt stort, dog stort nok,
2464 men det er svært hjelpevillig og engasjert.

2564 welcome to Angela Fuß. :)

2566 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
2568 <p
>I am a
39-year-old woman living in the very north of Germany near
2569 Denmark. I live in a patchwork family with
"my man
" Mike Gabriel, my
2570 two daughters, Mikes daughter and Mikes and my rather newborn son.
2572 <p
>At the moment - because of our little baby - I am spending most of
2573 the day by being a caring and organising mom for all the kids.
2574 Besides that I am really involved into and occupied with several inner
2575 growth processes: New born souls always bring the whole familiar
2576 system into movement and that needs time and focus ;-). We are also
2577 in the middle of buying a house and moving to it.
</p
>
2579 <p
>In
2013 I will work again in my job in a German foundation for
2580 nature conservation. I am doing public relation work there. Besides
2581 that - and that is the connection to Skolelinux / Debian Edu - I am
2582 working in our own school project
"IT-Zukunft Schule
" in North
2583 Germany. I am responsible for the quality assurance, the customer
2584 relationship management and the communication processes in the
2587 <p
>Since
2001 I constantly have been training myself in communication
2588 and leadership. Besides that I am a forester, a landscaping gardener
2589 and a yoga teacher.
</p
>
2591 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
2592 project?
</strong
></p
>
2594 <p
>I fell in love with Mike ;-).
</p
>
2596 <p
>Very soon after getting to know him I was completely enrolled into
2597 Free Software. At this time Mike did IT-services for one newly
2598 founded school in Kiel. Other schools in Kiel needed concepts for
2599 their IT environment. Often when Mike came home from working at the
2600 newly founded school I found myself listening to his complaints about
2601 several points where the communication with the schools head or the
2602 teachers did not work. So we were clear that he would not work for
2603 one more school if we did not set up a structure for communication
2604 between him, the schools head, the teachers, the students and the
2607 <p
>Together with our friend and hardware supplier Andreas Buchholz we
2608 started to get an overview of free software solutions suitable for
2609 schools. One day before Christmas
2010 Mike and I had a date with Kurt
2610 Gramlich in Gütersloh. As Kurt and I are really interested in building
2611 networks of people and in being in communication we dived into
2612 Skolelinux and brought it to the first grammar schools in Northern

2619 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
2620 Edu?
</strong
></p
>
2622 <p
>First I have to say: I cannot answer this question technically. My
2623 answer comes rather from a social point of view.
</p
>
2625 <p
>The biggest advantage of Skolelinux / Debian Edu I see is the large
2626 and strong international community of Debian Developers in the
2627 background which is very alive and connected over mailinglists, blogs
2628 and meetings. My constant feeling for the Debian Community is: If
2629 something does not work they will somehow fix it. All is well
2630 ;-). This is of course a user experience. What I also get as a big
2631 advantage of Skolelinux / Debian Edu is that everybody who uses it and
2632 works with it can also contribute to it - that includes students,
2633 teachers, parents...
</p
>
2635 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
2636 Edu?
</strong
></p
>
2638 <p
>I will answer this question relating to the internal structure of
2639 Skolelinux / Debian Edu.
</p
>
2641 <p
>What I see as a major disadvantage is that there is a gap between
2642 the group of developers for Debian Edu and the people who make the
2643 marketing, that means the people that bring Skolelinux to the
2644 schools. There is a lack of communication between these two groups and
2645 I think that does not really work for Skolelinux / Debian Edu.
</p
>
2647 <p
>Further I appreciate that Skolelinux / Debian Edu is known as a
2648 do-ocracy. Nevertheless I keep asking myself if at some points a
2649 democracy or some kind of hierarchical project structure would be good
2650 and helpful. I am also missing some kind of contact between the
2651 Skolelinux / Debian Edu communities in Europe or on an international
2652 level. I think it would be good if there was more sharing between the
2653 different countries using Skolelinux / Debian Edu.

2655 <p
><strong
>Which free software do you use daily?
</strong
></p
>
2657 <p
>On my laptop I am still using an Ubuntu
10.04 with a Gnome Desktop
2658 on. As applications I use Openoffice.org, Gedit, Firefox, Pidgin,
2659 LaTeX and GnuCash. For mails I am using Horde. And I am really fond of
2660 my N900 running with Maemo.
</p
>
2662 <p
><strong
>Which strategy do you believe is the right one to use to
2663 get schools to use free software?
</strong
></p
>
2665 <p
>I am really convinced that in our school project
"IT-Zukunft
2666 Schule
" we have developed (and keep developing) a great way to get
2667 schools to use Free Software. We have written a detailed concept for
2668 that so I cannot explain the whole thing here. But in a nutshell the
2669 strategy has three crucial pillars:
</p
>
2673 <li
>We really take time to get what sort of stories, questions and
2674 concerns the schools head and the teachers have about using different
2675 kinds of IT and we take time to enrol them into Free Software.
</li
>
2677 <li
>Our solution for schools is never just technical. In the centre
2678 are always the people who are going to use the software. From the very
2679 beginning of the planning for a school, we tell the schools head that
2680 they are paying us not only for a technical solution for their school,
2681 they also pay us for leading all the communication processes
2682 needed. If they do not want that, we are not working with them because
2683 we cannot give a guarantee for the quality of our work then.
</li
>
2685 <li
>Another focus lies in the training of teachers and students in
2686 co-administrating the IT-System at their school. They start getting in
2687 contact with the Skolelinux / Debian Edu community and they get the
2688 offer to become more and more independent from us.

</p

2711 <p
>I sommer (
2012-
07-
23) hadde Fremover et oppslag om at Narvik
2712 kommune hadde spart mellom
10 og
20 millioner kroner de siste årene på
2713 å bruke Skolelinux på sine skoler. Harstad har også tatt i bruk
2714 Skolelinux på alle sine skoler. Som tidligere Ballangsværing gledet
2715 det meg stort å se at skoleløsningen vi har utviklet siden
2001 tas i
2716 bruk i området der jeg vokste opp, og dermed bidrar til en bedre og
2717 billigere skolehverdag.
</p
>
2719 <p
>Skolelinux er en komplett IT-løsning for elevnettverket på en
2720 skole, med både nettverkstjenester og løsning for elevmaskiner med
2721 pedagogisk programvare, som tillater en å øke levetiden på en
2722 datamaskin i skolen med mange år. En undersøkelse publisert i mars
2723 2012 viste at de
56 norske skolene som har offentliggjort at de bruker
2724 Skolelinux eller annen Linuxutgave hadde
36% større PC-tetthet enn
2725 landsgjennomsnittet, når en ser på tall rapportert til Grunnskolens
2726 Informasjonssystem. I følge Paul Reidar Løsnesløkken, IKT-konsulent i
2727 Nord-Odal, fungerer datamaskiner godt til de er
8 til
10 år gamle.
</p
>
2729 <p
>I høst (
2012-
09-
29) fortalte Fremover hvordan Ballangen kommune har
2730 opparbeidet seg
20 millioner i underskudd og nok havner på Robek-lista
2731 fra nyttår. Kanskje Ballangen også burde ta i bruk Skolelinux for å
2732 spare penger? Hvis kommunen mangler kompetanse lokalt på Linux finnes
2733 det kommersielle selskaper som tilbyr driftstjenester rundt
2734 Skolelinux, og jeg bør vel avsløre at jeg selv er involvert i et av
2735 dem, Skolelinux Drift AS. Kommunen kan dermed få hjelp hvis de ikke
2736 ønsker å bygge opp egen kompetanse.

2809 <p

2810 skrevet om til å akseptere ord med bindestrek (f.eks. «e-post»). Litt
2811 over
10.000 slike ordformer er lagt til i orddatabasen. I tillegg er
2812 det kommet en del nye ord og rettelser rapportert inn av de frivillige
2813 som gjennomfører korrektur av orddatabasen i prosjektet. For å få

>After a long break in my row of interviews with people in the
2904 <a href=
"http://www.skolelinux.org/
">Debian Edu and Skolelinux
</a
>
2905 community, I finally found time to wrap up another. This time it is
2906 Giorgio Pioda, which showed up on the mailing list at the start of
2907 this year, asking questions and inspiring us to improve the first time
2908 administrators experience with Skolelinux. :) The interview was
2909 conduced in May, but I only found time to publish it now.
</p
>
2911 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
2913 <p
>I have a PhD in chemistry but since several years I work as teacher
2914 in secondary (
15-
18 year old students) and tertiary (a kind of
"light
"
2915 university) schools. Five years ago I started to manage a Learning
2916 Management Service server and slowly I got more and more involved with
2917 IT.
3 years ago the graduating schools moved completely to Linux and I
2918 got the head of the IT for this. The experience collected in chemistry
2919 labs computers (for example NMR analysis of protein folding) and in
2920 the IT-courses during university where sufficient to start. Self
2921 training is anyway very important
</p
>
2923 <p
>I live in the Italian speaking part of Switzerland, and the
2924 <a href=
"http://www.spse.ch/
">SPSE school
</a
> (secondary) is a very
2925 special sport school for young people who try to became sport pro (for
2926 all sports, we have dozens of disciplines represented) and we are
2927 recognised by the Olympic Swiss Organisation.
2929 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
2930 project?
</strong
></p
>
2932 <p
>Looking for Linux / Primary Domain Controller (PDC) I found it
2933 already several years ago. But since the system was still not
2934 Kerberized and since our schools relies strongly on laptops I didn
't
2935 use it. I plan to introduce it in the next future, probably for the
2936 next school year, since the squeeze release solved this security
2939 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
2940 Edu?
</strong
></p
>
2942 <p
>Many. First of all there is a strong and living community that is
2943 very generous for help and hints. Chat help is crucial, together with
2944 the mailing list. Second. With Skolelinux you get an already well
2945 engineered platform and you don
't have to start to build up your PDC
2946 and your clients from GNU/scratch; I
've already done this once and I
2947 can tell it, it is hard. Third, since Skolelinux is a standard
2948 platform, it is way easier to educate other IT people and even if the
2949 head IT is sick another one could pick up the task without too much
2952 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
2953 Edu?
</strong
></p
>
2955 <p
>The only real problem I see is that it is a little too less
2956 flexible at client level. Debian stable is rocky and desirable, but
2957 there are many reasons that force for another choice. For example the
2958 need of new drivers for new PC, or the need for a specific OS for some
2959 devices that have specific software packages for another specific
2960 distribution (I have such a case for whiteboards that have only
2961 Ubuntu packages). Thus, I prepared compatibility packages educlient
2962 and eduroaming, hoping not to use them ;-)
</p
>
2964 <p
><strong
>Which free software do you use daily?
</strong
></p
>
2966 <p
>I have a Debian Stable PDC at school (Kerberos, NIS, NFS) with
2967 mixed Debian and Ubuntu clients. If you think that this triad
2968 combination is exotic... well I discovered right yesterday that
2969 <a href=
"http://moo.nac.uci.edu/~hjm/Perceus-Report.html
">Perceus
</a
>
2970 has the same...
</p
>
2972 <p
>For myself I run Debian wheezy/sid, but this combination is good
2973 only I you have enough competence to fix stuff for yourself, if
2974 something breaks. Daily I use texmacs, gnumeric, a little bit of R
2975 statistics, kmplot, and less frequently OpenOffice.org.
</p
>
2977 <p
><strong
>Which strategy do you believe is the right one to use to
2978 get schools to use free software?
</strong
></p
>
2980 <P
>I think that the only real argument that school managers
"hear
" is
2981 cost reduction. They don
't give too much weight on quality, stability,
2982 just because they are normally not open to change.
</p
>
2984 <p
>Students adapts very quickly to GNU/Linux (and for them being able
2985 to switch between different OS is a plus value); teachers and managers
2986 don
't.
</p
>
2988 <p
>We decided to move to Linux because students at our school have own
2989 laptop and we have the responsibility to keep the laptop ready to use;
2990 we were really unsatisfied with Microsoft since every Monday we had
20
2991 machine to fix for viral infections... With Linux this has been
2992 reduced to zero, since people installs almost only from official
2993 repositories. I think that our special needs brought us to Linux.
2994 Those who don
't have such needs will hardly move to Linux.

4 og

3008 henvendelser til avisen for å få artikkelen på nett har så langt ikke
3009 vært vellykket.
</p

3011 <p
>Artikkelen med tittelen
"Narvik kommune bruker gratisprogram i
3012 skolen - Har spart millioner
", forteller om hvordan bruken av
3013 Skolelinux er en stor suksess i Narvik siden det ble tatt i bruk i
3014 2004. Her er noen fine sitater:
</p
>
3017 "- Skolelinux har spart kommunen for store pengesummer, millionbeløp,
3018 som de heller kan bruke på andre ting, sier IKT-konsulent Viggo
3022 <p
>Avisen forteller at de har fått tilgang til beregninger som viser
3023 at Narvik kommune har spart noe mellom
10 og
20 millioner kroner de
3024 siste
8 årene på å bruke Skolelinux, og fortsetter:
</p
>
3028 "Regnestykket tar høyde for sparte kostnader til lisenser som medfølger
3029 de alternative operativsystemene, lavere driftskostnader og lengre
3030 levetid på datautstyret. Totalt har Narvikskolen en maskinpark på
3031 1600 maskiner fordelt på de
11 skolene fra Skjomen i sør til Bjerkvik
3036 <p
>Viggo Fedreheim sier dette om hvor noe av gevinsten kommer fra:
</p
>
3039 "- Vi kan gjenbruke gamle maskiner i skolen som er for dårlig andre
3040 steder i kommunen der de ikke bruker Skolelinux. Levetiden på en
3041 datamaskin blir
3-
5 år lenger med Skolelinux. Vi kaller det for
3042 grønn IT, miljøvennlig IT.
"
3045 <p
>Her er det mulighet for flere kommuner å få et godt IT-system på
3046 skolene, hvis de er villige til å forsøke. De som ikke har kompetanse
3047 innomhus kan kjøpe det fra en av de kommersielle leverandørene av

'm a

12 years at
3123 the same school as
50% IT-manager and

3124 background is fil.kand in history and religious beliefs, an exam as a
3125 "folkhighschool

3126 Norwegian I believe it
's called
"Vuxenupplaring

3127 in

'm not really a tech guy, I
3128 just like to study how humans and technology interact and that is my
3129 perspective when working with IT.
</p
>
3131 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
3132 project?
</strong
></p
>
3134 I have followed the Skolelinux project for quite some time by
3135 now. Earlier I tested out the K12-LTSP project, which we used for some
3136 time, but I really like the idea of having a distribution aimed to be
3137 a complete solution for schools with necessary tools integrated. When
3138 K12-LTSP abandoned that idea some years ago, I started to look more
3139 seriously into Skolelinux instead.
3141 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
3142 Edu?
</strong
></p
>
3144 The big point of Skolelinux to me is that it is a complete
3145 distribution, ready to install. It has LDAP-support, MS Windows
3146 integration tools and so forth already configured, saving an
3147 administrator a lot of time and headache. We were using another Linux
3148 based thin-client system called Thinlinc, that has served us very
3149 well. But that Skolelinux is based on VNC and LTSP, to me, is better
3150 when it comes to the kind of multimedia used in schools. That is
3151 showing videos from Youtube or educational TV. It is also easier to
3152 mix thin clients with workstations, since the user settings will be the
3153 same. In our VNC-based solution you had to
"beat around the bush
" by
3154 setting up a second, hidden, home-directory for user settings for the
3155 workstations, because they will be different from the ones used on the
3156 thin clients. Skolelinux support for diskless workstations are very
3157 convenient since a school today often need to use a class room
3158 projector showing videos in full screen. That is easily done with a
3159 small integrated media computer running as a diskless workstation. You
3160 have only two installs to update and configure. One for the thin
3161 clients and one for the workstations. Also saving a lot of time. Our
3162 old system was also based on Redhat and CentOS. They are both very
3163 nice distributions, but they are sometimes painfully slow when it
3164 comes to updating multimedia support and multimedia programs (even
3165 such as Gimp), leaving us with a bit
"oldish
" applications. Debian is

>What do you see as the disadvantages of Skolelinux/Debian
3169 Edu?
</strong

3171 <p
>Debian is a bit too quick when it comes to updating. As an example
3172 we use old HP terminals as thinclients, and two times already this
3173 year (
2012) the updates you get from the repositories has stopped
3174 sound from working with them. It
's a kernel/ALSA issue. So you have
3175 to be more careful properly testing the updates before you run them in
3176 a production environment. This has never happened with CentOS.
</p
>
3178 <p
>I also would like to be able to set my own domain-settings at
3179 install time. In Skolelinux they are kind of hard coded into the
3180 distribution, when it comes to LDAP and at least samba integration.
3181 That is more a cosmetic/translation issue, and not a real problem.
3182 Running MS Windows applications within the Skolelinux environment needs
3183 to be better supported. That is, running them seamlessly via RDP, and
3184 support for single-sign on. That will make the transition to free
3185 software easier, because you can keep the applications you really
3186 need. No support will make it impossible if you work in a school where
3187 some applications can
't be open source. As for us we really need to
3188 run Adobe InDesign in our journalist classes. We run a journalist
3189 education, and is one of the very few non university ones that is ok:d
3190 by Svenska journalistförbundet (Swedish journalist association). Our
3191 education gives the pupils the right of membership there, once they
3192 are done. This is important if you want to get a job.
</p
>
3194 <p
>Adobe InDesign is the program most commonly used in newspapers and
3195 magazines. We used Quark Express before, but they seem to loose there
3196 market to Adobe. The only
"equivalent
" to InDesign in the opensource
3197 world is Scribus, and its not advanced enough. At least not according
3198 to the teacher. I think it would be possible to use it, because they
3199 are not supposed to learn a program, they are supposed to learn how to
3200 edit and compile a newspaper. But politically at our school we are not
3201 there yet. And Scribus lacks a lot of things you find i InDesign.
</p
>
3203 <p
>We used even a windows program for sound editing when it comes to
3204 the radio-journalist part. The year to come we are going to try
3205 Audacity. That software has the same kind of limitations compared to
3206 Adobe Audition, but that teacher is a bit more open minded. We have
3207 tried Ardour also, but that instead is more like a music studio
3208 program, not intended for the kind of editing taking place in a radio
3209 studio. Its way to complex and the GUI is to scattered when you only
3210 want to cut, make pass-overs, add extra channels and normalise. Those
3211 things you can do in Audacity, but its not as easy as in Audition. You
3212 have to do more things manually with envelopes, and that is a bit old
3213 fashion and timewasting. Its also harder to cut and move sound from
3214 one channel to another, which is a thing that you do frequently
3215 because you often find yourself needing to rearrange parts of the
3216 sound file.
</p
>
3218 <p
>So, I am not sure we will succeed in replacing even Audition, but we
3219 will try. The problem is the students have certain expectations when
3220 they start an education towards a profession. So the programs has to
3221 look and feel professional. Good thing with radio, there are many
3222 programs out there, that radio studios use, so its not as standardised
3223 as Newspaper editing. That means, it does not really matter what
3224 program they learn, because once they start working they still have to
3225 learn the program the studio uses, so instead focus has to be to learn
3226 the editing part without to much focus on a specific software.

><strong
>Which strategy do you believe is the right one to use to
3236 get schools to use free software?

3238 <p
>To get schools to use free software there has to be good open
3239 source software that are windows based, to ease the transition. But
3240 it
's also very important that the multimedia support is working
3241 flawlessly. The problems with Youtube, Twitter, Facebook and whatever
3242 will create problems when it comes to both teachers and
3243 students. Economy are also important for schools, so using thin
3244 clients, as long as they have good multimedia support, is a very good
3245 idea. It
's also important that the open source software works even for
3246 the administration. It
's hard to convince the teachers to stick with
3247 open source, if the principal has to run Windows. It also creates a
3248 problem if some classes has to use Windows for there tasks, since that
3249 will create a difference in
"status
" between classes, so a good
3250 support for running windows applications via the thin client (Linux)
3251 desktop is essential. At least at our school, where we have mixed
3252 level of educations, from high-school to journalist-school.

2000, der jeg måtte ha
"noe
3498 å gjøre
" under hjemturen over Atlanteren. Jeg kjøpte et par bøker om
3499 Linux i en bokhandel i New York og ble veldig fascinert. Etter
3500 hjemkomsten begynte jeg å jobbe på Ulsrud VGS, som naturfagslærer, men
3501 som IT-interessert ble jeg fort en del av den nye IT-satsningen som
3502 skulle løfte Ulsrud og gi skolen en bedre rykte. Vi hadde ganske
3503 mange maskiner, som gikk på Win98 og to servere som ble oppgradert til
3504 Win2000. Systemene var ustabil og dårlige. På leting etter noe
3505 bedre, uten å knekke ryggen økonomisk, kom jeg over
"Linux i Skolen
"
3506 og Skolelinux. Jeg tok kontakt med miljøet og en gjeng møtte opp på
3507 skolen, der vi gjorde en liten testinstallasjon. Etter et par år var
3508 ryggraden på skolen Linux (Skolelinux) og vi hadde flere hundre
3509 maskiner, både tynne klienter (gamle og nye), bærbare (Debian) og noen
3510 stasjonære (Win2000). På et tidspunkt var Ulsrud den råeste IT-skolen
3511 og det irriterte skolesjefen i Oslo, da de satset hardt på

3516 <p
>Det som gjorde at vi fikk inn Skolelinux var ene og alene
3517 økonomiske. Det faktum at vi slapp å kjøpe masse nye lisenser og at
3518 vi kunne bruke gammel hardware. Alt i alt gjorde dette at vi sparte
3519 mye, men i stede for å bruke mindre på IT brukte vi det vi sparte på å
3520 skaffe mer hardware og på den måten gi det beste tilbudet i landet til
3521 våre elever. For oss som driftet var det himmel å ha et system som
3522 gikk å administrere sentralt og effektivt. Det var heller ikke så
3523 dumt at vi kunne
"låse
" maskinene mer effektivt enn vi kunne med
3524 Microsoft Windows, slik at vi slapp mye feil og problemer som ble
3525 forårsaket av
"kreative
" elever.

3530 Husker ikke alle, men det var et knippe med pedagogiske programmer de
3531 ikke fikk. I dag tror jeg det problemet er langt mindre da det meste
3532 av disse kjøres gjennom nettleseren.

3538 Firefox brukes mest av disse. På Apple-serveren hjemme bruker jeg
3539 HandBrake mye, og jeg har installert OpenWRT på flere av
3540 basestasjonene både hjemme og på jobben. I tillegg til det har jeg i
3541 flere år finansiert et prosjekt som heter
3542 <a href=

3543 vi lager et rammeverk for søk, der alt vi bruker fri programvare. Det

3547 skoler til å ta i bruk fri programvare?

3549 <p
>Når det gjelder IT og skole er fortsatt økonomi veldig viktig. Så
3550 man må oppfylle minimumskravene (ikke være best, men bra nok) og selge
3551 seg inn på hvor mye man sparer. Det betyr selvsagt at man sparer på
3552 lisenser, men også på driftsinnsats. Men nå når jeg ikke er en aktiv
3553 del av miljøet lenger hører jeg nesten ingen ting om fri programvare.
3554 Jeg stiller meg da spørsmålet om det har blitt stille rundt miljøet,
3555 eller om jeg kun så det tydeligere før når jeg var aktiv? Uansett er
3556 det for stille rundt Skolelinux-prosjektet nå.

3566 another interview with the people behind
3567 <a href=

">Debian Edu and Skolelinux
</a
>.
3568 This time we get to know José Luis Redrejo Rodríguez, one of our great
3569 helpers from Spain. His effort was the reason we added support for
3570 several desktop types (KDE, Gnome and most recently LXDE) in Debian
3571 Edu, and have all of these available in the recently published

3577 <p
>I
'm a father, teacher and engineer who is working for the Education
3578 ministry of the Region of Extremadura (Spain) in the implementation of
3579 ICT in schools
</p

3581 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
3582 project?
</strong
></p
>
3584 <p
>At
2006, I verified that both, we in Extremadura and Skolelinux
3585 project, had been working in parallel for some years, doing very
3586 similar things, using very similar tools and with similar targets, so
3587 I decided it was time to join forces as much as possible.
</p

3589 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
3590 Edu?
</strong
></p
>
3592 <p
>A community of highly skilled experts working together, with a
3593 really open schema of collaboration and work. I really love the
3594 concepts of Do-ocracy and Merit-ocracy and the way these concepts are
3595 been used everyday inside Debian Edu.
</p
>
3597 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
3598 Edu?
</strong
></p
>
3600 <p
>Sometimes the differences in the implementations, laws or
3601 economical and technical resources in the different countries don
't
3602 allow us to agree in the same solution for all of us, and several
3603 approaches are needed, what is a waste of effort. Also, there is a
3604 lack of more man power to be able to follow the fast evolution of the
3605 technologies in school.
</p
>
3607 <p
><strong
>Which free software do you use daily?
</strong
></p

3609 <p
>Debian, of course, and due to my kind of job I am most of my time
3610 between Iceweasel,

</p
>
3613 <p
><strong
>Which strategy do you believe is the right one to use to
3614 get schools to use free software?
</strong
></p
>
3616 <p
>I think there is not a single strategy because there are very
3617 different scenarios: schools with mixed proprietary and free
3618 environments, schools using only workstations, other schools using
3619 laptops, netbooks, tablets, interactive white-boards, etc.
</p
>
3621 <p
>Also the range of ages of the students is very broad and you can
3622 not use the same solutions for primary schools and secondary or even
3623 universities. So different strategies are needed.
</p
>
3625 <p
>But, looking at these differences, and looking back to the things
3626 we
've done and implemented, and the places were we have spent most of
3627 our forces, I think we should focus as much as possible in free
3628 multi-platform environments, using only standards tools, and moving
3629 more and more to Internet or network solutions that could be deployed
3630 using wireless. I think we
'll see more and more personal devices in
3631 the schools, devices the students and teachers will take home with
3632 them, so the solutions must be able to be taken at home and continue
3633 working there.

20120311.nb.html
">Debian Edu
3644 based on Squeeze
</a
>, I came across some issues that should be
3645 addressed in the Wheezy release. I finally found time to wrap up my
3646 notes and provide quick summary of what I found, with a bit
3647 explanation.
</p
>
3651 <li
>We need to rewrite our package installation framework, as tasksel
3652 changed from using tasksel tasks to using meta packages (aka packages
3653 with dependencies like our education-* packages), and our installation
3654 system depend on tasksel tasks in
3655 /usr/share/tasksel/debian-edu-tasks.desc for package
3656 installation.
</li
>
3658 <li
>Enable Kerberos login for more services. Now with the Kerberos
3659 foundation in place, we should use it to get single sign on with more
3660 services, and avoiding unneeded password / login questions. We should
3661 at least try to enable it for these services:
3664 <li
>CUPS for admins to add/configure printers and users when using
3666 <li
>Nagios for admins checking the system status.
</li
>
3667 <li
>GOsa for admins updating LDAP and users changing their passwords.
</li
>
3668 <li
>LDAP for admins updating LDAP.
</li
>
3669 <li
>Squid for users when exam mode / filtering is active.
</li
>
3670 <li
>ssh for admins and users to save a password prompt.
</li
>
3672 </ul
></li
>
3674 <li
>When we move GOsa to use Kerberos instead of LDAP bind to
3675 authenticate users, we should try to block or at least limit access to
3676 use LDAP bind for authentication, to ensure Kerberos is used when it
3677 is intended, and nothing fall back to using the less safe LDAP bind
</li
>
3679 <li
>Merge debian-edu-config and debian-edu-install. The split made
3680 sense when d-e-install did a lot more, but these days it is just an
3681 inconvenience when we update the debconf preseeding values.
</li
>
3683 <li
>Fix partman-auto to allow us to abort the installation before
3684 touching the disk if the disk is too small. This is
3685 <a href=
"http://bugs.debian.org/
653305">BTS report #
653305</a
> and the
3686 d-i developers are fine with the patch and someone just need to apply
3687 it and upload. After this is done we need to adjust
3688 debian-edu-install to use this new hook.
</li
>
3690 <li
>Adjust to new LTSP framework (boot time config instead of install
3691 time config). LTSP changed its design, and our hooks to install
3692 packages and update the configuration is most likely not going to work
3695 <li
>Consider switching to NBD instead of NFS for LTSP root, to allow
3696 the Kernel to cache files in its normal file cache, possibly speeding
3697 up KDE login on slow networks.
</li
>
3699 <li
>Make it possible to create expired user passwords that need to
3700 change on first login. This is useful when handing out password on
3701 paper, to make sure only the user know the password. This require
3702 fixes to the PAM handling of kdm and gdm.
</li
>
3704 <li
>Make GUI for adding new machines automatically from sitesummary.
3705 The current command line script is not very friendly to people most
3706 familiar with GUIs. This should probably be integrated into GOsa to
3707 have it available where the admin will be looking for it..
</li
>
3709 <li
>We should find way for Nagios to check that the DHCP service
3710 actually is working (as in handling out IP addresses). None of the
3711 Nagios checks I have found so far have been working for me.
</li
>
3713 <li
>We should switch from libpam-nss-ldapd to sssd for all profiles
3714 using LDAP, and not only on for roaming workstations, to have less
3715 packages to configure and consistent setup across all profiles.
</li
>
3717 <li
>We should configure Kerberos to update LDAP and Samba password
3718 when changing password using the Kerberos protocol. The hook was
3719 requested in
<a href=
"http://bugs.debian.org/
588968">BTS report
3720 #
588968</a
> and is now available in Wheezy. We might need to write a
3721 MIT Kerberos plugin in C to get this.
</li
>
3723 <li
>We should clean up the set of applications installed by default.
3726 <li
>reduce the number of chemistry visualisers
</li
>
3727 <li
>consider dropping xpaint
</li
>
3728 <li
>and probably more?
</li
>
3729 </ul
></li
>
3731 <li
>Some hardware need external firmware to work properly. This is
3732 mostly the case for WiFi network cards, but there are some other
3733 examples too. For popular laptops to work out of the box, such
3734 firmware need to be installed from non-free, and we should provide
3735 some GUI to do this. Ubuntu already have this implemented, and we
3736 could consider using their packages. At the moment we have some
3737 command line script to do this (one for the running system, another
3738 for the LTSP chroot).
</li
>
3741 <li
>In Squeeze, we provide KDE, Gnome and LXDE as desktop options. We
3742 should extend the list to Xfce and Sugar, and preferably find a way to
3743 install several and allow the admin or the user to select which one to
3746 <li
>The golearn tool from the goplay package make it easy to check out
3747 interesting educational packages. We should work on the package
3748 tagging in Debian to ensure it represent all the useful educational
3749 packages, and extend the tool to allow it to use packagekit to install
3750 new applications with a simple mouse click.
</li
>
3752 <li
>The Squeeze version got half a exam solution already in place,
3753 with the introduction of iptable based network blocking, but for it to
3754 be a complete exam solution the Squid proxy need to enable
3755 filtering/blocking as well when the exam mode is enabled. We should
3756 implement a way to easily enable this for the schools that want it,
3757 instead of the
"it is documented
" method of today.
</li
>
3759 <li
>A feature used in several schools is the ability for a teacher to
3760 "take over
" the desktop of individual or all computers in the room.
3761 There are at least three implementations,
3762 <a href=
"italc.sourceforge.net/
">italc
</a
>,
3763 <a href=
"http://www.itais.net/help/en/
">controlaula
</a
> og
3764 <a href=
"http://www.epoptes.org/
">epoptes
</a
> and we should pick one of
3765 them and make it trivial to set it up in a school. The challenges is
3766 how to distribute crypto keys and how to group computers in one room
3767 and how to set up which machine/user can control the machines in a
3768 given room.
</li
>
3770 <li
>Tablets and surf boards are getting more and more popular, and we
3771 should look into providing a good solution for integrating these into
3772 the Debian Edu network. Not quite sure how. Perhaps we should
3773 provide a installation profile with better touch screen support for
3774 them, or add some sync services to allow them to exchange
3775 configuration and data with the central server. This should be
3776 investigated.

2010, Mike Gabriel showed up on the
3791 <a href=

3792 mailing list. He quickly proved to be a valuable developer, and

</p

3797 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
3799 <p
>My name is Mike Gabriel, I am
38 years old and live near Kiel,
3800 Schleswig-Holstein, Germany. I live together with a wonderful partner
3801 (Angela Fuß) and two own children and two bonus children (contributed
3802 by Angela).
</p
>
3804 <p
>During the day I am part-time employed as a system administrator
3805 and part-time working as an IT consultant. The consultancy work
3806 touches free software topics wherever and whenever possible. During
3807 the nights I am a free software developer. In the gaps I also train in
3808 becoming an osteopath.
</p
>
3810 <p
>Starting in
2010 we (Andreas Buchholz, Angela Fuß, Mike Gabriel)
3811 have set up a free software project in the area of Kiel that aims at
3812 introducing free software into schools. The project
's name is
3813 "IT-Zukunft Schule
" (IT future for schools). The project links IT
3814 skills with communication skills.
</p
>
3816 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
3817 project?
</strong
></p
>
3819 <p
>While preparing our own customised Linux distribution for
3820 "IT-Zukunft Schule
" we were repeatedly asked if we really wanted to
3821 reinvent the wheel. What schools really need is already available,
3822 people said. From this impulse we started evaluating other Linux
3823 distributions that target being used for school networks.
</p
>
3825 <p
>At the end we short-listed two approaches and compared them: a
3826 commercial Linux distribution developed by a company in Bremen,
3827 Germany, and Skolelinux / Debian Edu. Between
12/
2010 and
03/
2011 we
3828 went to several events and met people being responsible for marketing
3829 and development of either of the distributions. Skolelinux / Debian
3830 Edu was by far much more convincing compared to the other product that
3831 got short-listed beforehand--across the full spectrum. What was most
3832 attractive for me personally: the perspective of collaboration within
3833 the developmental branch of the Debian Edu project itself.
</p
>
3835 <p
>In parallel with this, we talked to many local and not-so-local
3836 people. People teaching at schools, headmasters, politicians, data
3837 protection experts, other IT professionals.
</p
>
3839 <p
>We came to two conclusions:
</p
>
3841 <p
>First, a technical conclusion: What schools need is available in
3842 bits and pieces here and there, and none of the solutions really fit
3843 by
100%. Any school we have seen has a very individual IT setup
3844 whereas most of each school
's requirements could mapped by a standard
3845 IT solution. The requirement to this IT solution is flexibility and
3846 customisability, so that individual adaptations here and there are
3847 possible. In terms of re-distributing and rolling out such a
3848 standardised IT system for schools (a system that is still to some
3849 degree customisable) there is still a lot of work to do here
3850 locally. Debian Edu / Skolelinux has been our choice as the starting
3853 <p
>Second, a holistic conclusion: What schools need does not exist at
3854 all (or we missed it so far). There are several technical solutions
3855 for handling IT at schools that tend to make a good impression. What
3856 has been missing completely here in Germany, though, is the enrolment
3857 of people into using IT and teaching with IT.
"IT-Zukunft Schule
"
3858 tries to provide an approach for this.
</p
>
3860 <p
>Only some schools have some sort of a media concept which explains,
3861 defines and gives guidance on how to use IT in class. Most schools in
3862 Northern Germany do not have an IT service provider, the school
's IT
3863 equipment is managed by one or (if the school is lucky) two (admin)
3864 teachers, most of the workload these admin teachers get done in there
3865 spare time.
</p
>
3867 <p
>We were surprised that only a very few admin teachers were
3868 networked with colleagues from other schools. Basically, every school
3869 here around has its individual approach of providing IT equipment to
3870 teachers and students and the exchange of ideas has been quasi
3871 non-existent until
2010/
2011.
</p
>
3873 <p
>Quite some (non-admin) teachers try to avoid using IT technology in
3874 class as a learning medium completely. Several reasons for this
3875 avoidance do exist.
</p
>
3877 <p
>We discovered that no-one has ever taken a closer look at this
3878 social part of IT management in schools, so far. On our quest journey
3879 for a technical IT solution for schools, we discussed this issue with
3880 several teachers, headmasters, politicians, other IT professionals and
3881 they all confirmed: a holistic approach of considering IT management
3882 at schools, an approach that includes the people in place, will be new
3883 and probably a gain for all.
</p
>
3885 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
3886 Edu?
</strong
></p
>
3888 <p
>There is a list of advantages: international context, openness to
3889 any kind of contributions, do-ocracy policy, the closeness to Debian,
3890 the different installation scenarios possible (from stand-alone
3891 workstation to complex multi-server sites), the transparency within
3892 project communication, honest communication within the group of
3893 developers, etc.

3896 Edu?
</strong

3898 <p
>Every coin has two sides:
</p
>
3900 <p
>Technically:
<a href=
"http://bugs.debian.org/
311188">BTS issue
3901 #
311188</a
>, tricky upgradability of a Debian Edu main server, network
3902 client installations on top of a plain vanilla Debian installation
3903 should become possible sometime in the near future, one could think
3904 about splitting the very complex package debian-edu-config into
3905 several portions (to make it easier for new developers to
3906 contribute).
</p
>
3908 <p
>Another issue I see is that we (as Debian Edu developers) should
3909 find out more about the network of people who do the marketing for
3910 Debian Edu / Skolelinux. There is a very active group in Germany
3911 promoting Skolelinux on the bigger Linux Days within Germany. Are
3912 there other groups like that in other countries? How can we bring
3913 these marketing people together (marketing group A with group B and
3914 all of them with the group of Debian Edu developers)? During the last
3915 meeting of the German Skolelinux group, I got the impression of people
3916 there being rather disconnected from the development department of
3917 Debian Edu / Skolelinux.

3921 <p

3923 <p

3924 serious text writing I prefer LaTeX. I use gimp, inkscape, scribus for
3925 more artistic tasks. I run virtual machines in KVM and Virtualbox.

3929 PyHoca-GUI has brought forth a Python X2Go Client API that currently
3930 is being integrated in Ubuntu
's software center.

3932 <p
>For communications I have my own Kolab server running using Horde
3933 as web-based groupware client. For IRC I love to use irssi, for Jabber

3978 <p
>We had tried different Linux based school servers, when members of
3979 my local Linux User Group (LUG OWL) detected Skolelinux. I remember
3980 very well, being part of a party celebrating the Linux New Media Award
3981 (
"Best Newcomer Distribution
", also nominated: Ubuntu) that was given
3982 to Skolelinux at Linux World Exposition in Frankfurt,
2005 (IIRC). Few
3983 months later, I had the chance to join a developer meeting in Ulsrud
3984 (Oslo) and to hand out the award to Knut Yrvin and others. For more
3985 than
7 years, Skolelinux is part of our schools infrastructure, namely
3986 our main server (tjener), one LTSP (today without thin clients), and
3987 approximately
50 work stations. Most of these have the option to boot a
3988 locally installed Skolelinux image. As a consequence, I joined quite
3989 a few events dealing with free software or Linux, and met many Debian
3990 (Edu) developers. All of them seemed quite nice and competent to me,
3991 one more reason to stick to Skolelinux.

3996 <p
>Debian driven, you are given all the advantages of a community
3997 project including well maintained updates. Once, you are familiar with
3998 the network layout, you can easily roll out an entire educational
3999 computer infrastructure, from just one installation media. As only
4000 free software (FOSS) is used, that supports even elderly hardware,
4001 up-sizing your IT equipment is only limited by space (i.e. available
4002 labs). Especially if you run a LTSP thin client server, your
4003 administration costs tend towards zero.

>What do you see as the disadvantages of Skolelinux/Debian
4006 Edu?
</strong

4008 <p
>While Debian
's stability has loads of advantages for servers, this
4009 might be different in some cases for clients: Schools with unlimited
4010 budget might buy new hardware with components that are not yet
4011 supported by Debian stable, or wish to use more recent versions of
4012 office packages or desktop environments. These schools have the
4013 option to run Debian testing or other distributions - if they have the
4014 capacity to do so. Another issue is that Debian release cycles
4015 include a wide range of changes; therefor a high percentage of human
4016 power seems to be absorbed by just keeping the features of Skolelinux
4017 within the new setting of the version to come. During this process,
4018 the cogs of Debian Edu are getting more and more professional,
4019 i.e. harder to understand for novices.

4023 <p

>Support computer science as regular subject in schools to make
4033 people really
"own
" their hardware, to make them understand the
4034 difference between proprietary software products, and free software
4035 developing.
</li
>
4037 <li
>Make budget baskets corresponding: In Germany
's public schools
4038 there are more or less fixed budgets for IT equipment (including
4039 licenses), so schools won
't benefit from any savings here. This
4040 privilege is left to private schools which have consequently a large
4041 share among German Skolelinux schools.
</li
>
4043 <li
>Get free software in the seminars where would-be teachers are
4044 trained. In many cases, teachers
' software customs are respected by
4045 decision makers rather than the expertise of any IT experts.
</li
>
4047 <li
>Don
't limit ourself to free software run natively. Everybody uses
4048 free software or free licenses (for instance Wikipedia), and this
4049 general concept should get expanded to free educational content to be
4050 shared world wide (school books e.g.).
</li
>
4052 <li
>Make clear where ever you can that the market share of free (libre)
4053 office suites is much above
20 p.c. today, and that you pupils don
't
4054 need to know the
"ribbon menu
" in order to get employed.
</li
>
4056 <li
>Talk about the difference between freeware and free software.
</li
>
4058 <li
>Spread free software, or even collections of portable free apps
4059 for USB pen drives. Endorse students to get a legal copy of
4060 Libreoffice rather than accepting them to use illegal serials. And
4061 keep sending documents in ODF formats.

4078 intervjurunde av folkene bak Skolelinux-løsningen. Jeg har kjent Alf

4080 gledelig overrasket da han dukket opp i Skolelinux-prosjektet etter å
4081 ikke ha sett noe til ham på mange år.

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

4085 <p
>Jeg er utdannet kokk av yrke, og har utøvet yrket i
12 år. Men
4086 etter at ryggen sa takk før seg, studerte jeg nettverksadministrasjon
4087 ved Næringsakademiet i Bergen årene
2008-
2009 slik at jeg kunne
4088 forfølge en av mine største interesser - data. Til daglig jobber jeg
4089 ved
<a href=

">Parken
4090 ungdomsskole
</a
> med å drifte skolens PC-er. Har også litt
4091 musikkundervisning.
</p
>
4093 <p
>Mitt mål er å bevisstgjøre musikklærene mulighetene med de frie
4094 programmene som finnes i Skolelinux, blant annet Rosegarden.
</p
>
4096 <p
>Har i mange år drevet med musikk og en av grunnen til at Rosegarden
4097 falt i smak for min del, var fordi denne fungere og ligner mest på
4098 Windows-programmet (cubase) jeg jobbet mye med da jeg i mine yngre
4099 dager var «Windows fanatiker». Ble introdusert til Linux av en kompis
4100 av meg for omtrent
14 år siden, og har bare blitt mer og mer glad i
4101 dette operativsystemet.

>
4103 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
4105 <p
>Da jeg ble sykemeldt fra min gamle jobb, og måtte omskoleres,
4106 havnet jeg i
2007 sammen med Viggo Fedreheim på IKT-avdelingen i
4107 Narvik kommune, der ble jeg for første gang introdusert til
4108 Skolelinuxprosjektet.
</p
>
4110 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
4112 <p
>Skolelinux er enkelt å holde i drift og masse flotte programmer som
4113 geogebra, ktouch og kgeografi følger med pakken. Man kan ta i bruk
4114 gamle PC-er igjen, slik at skoler med dårlig råd får opp en brukbar
4115 PC-park. PC-er som er ca
6-
9 år gamle fungere tilfredstillende, bare
4116 de har
512 MB RAM eller mer.
</p
>
4118 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
4120 <p
>Ulempene er at noen av de pedagogiske programmene som lærene ønsker
4121 å bruke fungere dårlig med Linux. Mye pga. av at disse programmene
4122 blir ikke laget til Linuxbaserte operativsystemer.
</p
>
4124 <p
>Video- og bilde-redigering har dessverre en del mangler, mange av
4125 programmene har en tendens til og krasje. Det gjelder blant annet
4126 <a href=
"http://www.kdenlive.org/
">kdenlive
</a
> og
4127 <a href=
"http://www.openshotvideo.com/
">openshot
</a
>, for å nevne
4128 noen. De er ikke stabile nok. Når elevene kommer med filmsnutter de
4129 ønsker og jobbe med, så godtar ikke programmene filene, og når elevene
4130 jobber med redigering bare krasjer programmene uten forvarsel. Det er
4131 for vanskelig å få noe som bare fungerer ut av boksen her. Når en elev
4132 plugger inn et videokamera eller fotoapparat så er det alltid noe som
4133 ikke vil fungere. Programmene godtar ikke format, godtar ikke
4134 kameraet, osv., osv. Det er dessverre med på og dra ned en positiv
4135 opplevelse av bruk av fri programvare.
</p
>
4137 <p
>Man må ofte bruke flere en et video redigerings program før og få
4138 fullført en ønsket oppgave.
</p
>
4140 <p
>Eksempel:
</p
>
4142 <p
>Hvis det ene programmet ikke vil ta i mot videofilen klarer et
4143 annet det, men det programmet som klarer det kan ikke gjøre de samme
4144 oppgavene som det programmet som ikke ville ta i mot filen,
4145 Tilsvarende er det med foto, man må bruke flere programmer for å få
4146 et ferdig resultat. Til dags dato har jeg enda ikke funnet et video-
4147 og fotoprogram som kan tilfredstillende fullføre en oppgave.
</p
>
4149 <p
>Så man kan klare og fullføre en oppgave, men i verste fall må man
4150 innom
3-
4 programmer for å få det til. Så jeg har enda ikke til dags
4151 dato sett at et program fungere
100% til alt.
</p
>
4153 <p
>Det programmet jeg har best erfaring til er
4154 <a href=
"http://cinelerra.org/
">cinelerra
</a
>, men dessverre har det
4155 også tendenser og krasje av og til uten grunn.
</p
>
4157 Lydsystemet kan også være et mareritt. Konkret snakker jeg om når du
4158 bruker for eksempel et smartboard, så følger det med USB-lydkort på
4159 disse. Problemet ligger her i at systemet ikke vil velge rett
4160 lydkort, så man må inn med padevchooser for å sette opp PulseAudio
4161 til og velge at USB-lydkortet skal brukes. Det blir for tungvindt for
4162 lærene, de ønsker at ting skal fungere med en gang. (min løsning på
4163 det problemet ble at jeg måtte deaktivere lydkortet som fantes på
4164 maskinen) men da må man bestandig slå på smartboard-tavla.
4166 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
4168 Programmene jeg bruker mest av er: Rosegarden, jack, qsynth, audacity,
4169 k3b, openttd og libreoffice.
4171 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
4172 skoler til å ta i bruk fri programvare?
</strong
></p
>
4174 Jeg tror det må bevisstgjøring av Skolene til, dvs. reklamere høylytt
4175 og fortelle og vise de andre skolene at frie programvarer faktisk
4176 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
4187 publish another interview with the people behind
4188 <a href=
"http://www.skolelinux.org/
">Debian Edu and Skolelinux
</a
>.
4189 This time it is one of our German developers, who have helped out over the
4190 years to make sure both a lot of major but also a lot of the minor
4191 details get right before release.
4193 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
4195 <p
>My name is Jürgen Leibner, I
'm
49 years old and living in
4196 Bielefeld, a town in northern Germany. I worked nearly
20 years as
4197 certified engineer in the department for plant design and layout of an
4198 international company for machinery and equipment. Since
2011 I
'm a
4199 certified technical writer (tekom e.V.) and doing technical
4200 documentations for a steam turbine manufacturer. From April this year
4201 I will manage the department of technical documentation at a
4202 manufacturer of automation and assembly line engineering.
</p
>
4204 <p
>My first contact with linux was around
1993. Since that time I used
4205 it at work and at home repeatedly but not exclusively as I do now at
4206 home since
2006.
</p
>
4208 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4209 project?
</strong
></p
>
4211 <p
>Once a day in the early year of
2001 when I wanted to fetch my
4212 daughter from primary school, there was a teacher sitting in the
4213 middle of
20 old computers trying to boot them and he failed. I helped
4214 him to get them booting. That was seen by the school director and she
4215 asked me if I would like to manage that the school gets all that old
4216 computers in use. I answered:
"Yes
".
</p
>
4218 <p
>Some weeks later every of the
10 classrooms had one computer
4219 running Windows98. I began to collect old computers and equipment as
4220 gifts and installed the first computer room with a peer-to-peer
4221 network. I did my work at school without being payed in my spare time
4222 and with a lot of fun. About one year later the school was connected
4223 to Internet and a local area network was installed in the school
4224 building. That was the time to have a server and I knew it must be a
4225 Linux server to be able to fulfil all the wishes of the teachers and
4226 being able to do this in a transparent and economic way, without extra
4227 costs for things like licence and software. So I searched for a
4228 school server system running under Linux and I found a couple of
4229 people nearby who founded
'skolelinux.de
'. It was the Skolelinux
4230 prerelease
32 I first tried out for being used at the school. I
4231 managed the IT of that school until the municipal authority took over
4232 the IT management and centralised the services for all schools in
4233 Bielefeld in December of
2006.

4235 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4236 Edu?
</strong

>
4238 <p
>When I
'm looking back to the beginning, there were other advantages
4239 for me as today.
</p
>
4241 <p
>In the past there were advantages like:
</p
>
4245 <li
>I don
't need to buy it so it generates no costs to the school as
4246 they had little money to spent for computers and software.
</li
>
4248 <li
>It has a licence which grands all rights to use it without
4251 <li
>It was more able to fit all requirements of a server system for
4252 schools than a Microsoft server system, even if there are only Windows
4253 clients because of it
's preconfigured overall concept of being a
4254 infrastructure solution and community for schools, not only a
4257 <li
>I was able to configure the server to the needs of the
4260 </ul
></p
>
4262 <p
>Today some of the advantages has been lost, changed or new ones
4263 came up in this way:
</p
>
4267 <li
>Most schools here do have money to buy hardware and software
4270 <li
>They are today mostly managed from central IT departments which
4271 have own concepts which often do not fit to Debian Edu concepts
4272 because they are to close to Microsoft ideology.
</li
>
4274 <li
>With the Squeeze version of Debian Edu which now uses GOsa² for
4275 management I feel more able to manage the daily tasks than with the
4276 interfaces used in the past.
</li
>
4278 <li
>It is more modular than in the past and fits even better to the
4279 different needs.
</li
>
4281 <li
>The documentation is usable and gets better every day.
</li
>
4283 <li
>More people than ever before are using Debian Edu all over the
4284 world and so the community, which is an very important part I think,
4285 is sharing knowledge and minds.
</li
>
4287 <li
>Most, maybe all, of the technical requirements for schools are
4288 solved today by Debian Edu.

4297 <li
>There are too few IT companies able to integrate Debian Edu into
4298 their product portfolio for serving schools with concepts or even
4299 whole municipality areas.

4301 <li
>Debian Edu has beside other free and open software projects not
4302 enough lobbyists which promote free and open software to

4311 <p

4312 computer. On my laptop I use Debian testing/sid. The applications I
4313 use on my laptop and my desktop are Open/Libre-office, Iceweasel,
4314 KMail, DigiKam, Amarok, Dolphin, okular and all the other programs I
4315 need from the KDE environment. On console I use newsbeuter, mutt,
4316 screen, irssi and all the other famous and useful tools.
</p

4318 <p
>My home server provides mail services with exim, dovecot, roundcube
4319 and mutt over ssh on the console, file services with samba, NFS,
4320 rsync, web services with apache, moinmoin-wiki, multimedia services
4321 with gallery2 and mediatomb and database services with MySQL for me

>Da jeg googlet etter noe annet kom jeg tilfeldigvis over
4339 <a href=
"http://www.duo.uio.no/sok/work.html?WORKID=
58309">en
4340 hovedfagsoppgave
</a
> ved Universitetet i Oslo som diskuterer verdien
4341 av GPLs fire friheter for brukerne av IT-systemer. Jeg ble fascinert
4342 over det som presenteres der. Her er sammendraget:
</p
>
4344 <p
><blockquote
>
4346 <p
>Motivasjonen til å skrive denne oppgaven er en personlig undring
4347 over hvorfor det primært, og ofte eksklusivt, fokuseres på det
4348 økonomiske aspektet ved utredninger om fri programvare er et godt valg
4349 for det offentlige. Fri og produsenteid programvare bygger på
4350 fundamentalt forskjellige ideologier som kan ha implikasjoner utover
4351 økonomiske kostnader. Kunnskapskulturen som er med på å definere fri
4352 programvare er basert på åpenhet, og er en verdi i seg selv.
</p
>
4354 <p
>Oppgavens tema er programvarelisensen GPL og frihet. GPL-lisensiert
4355 programvare gir visse friheter i forhold til produsenteid
4356 programvare. Mitt spørsmål er om, og eventuelt i hvilken utstrekning,
4357 disse frihetene blir benyttet av ulike brukere og hvordan de
4358 manifesterer seg for disse brukerne. Sentrale spørsmål i oppgaven
4362 <li
>Hvordan fordeles handlekraft gjennom lisensieringen av programvaren?
</li
>
4363 <li
>Hvilke konsekvenser har programvarelisensen for de ulike brukere?
</li
>
4366 <p
>Fri programvare gir blant annet brukeren mulighet til å studere og
4367 modifisere kildekoden. Denne formen for frihet erverves gjennom
4368 kunnskap og krever at brukeren også er en ekspert. Hva skjer med
4369 frihetene til GPL når sluttbrukeren er en annen? Dette diskuteres i
4370 dialog med informantene.
</p
>
4372 <p
>Jeg har i denne oppgaven samlet inn intervjudata fra IKT-ansvarlige
4373 ved grunnskolene i Nittedal kommune, driftsansvarlig og IKT-veilederen
4374 for skolene i kommunen, samt IKT-koordinator for utdanning i Akershus
4375 fylkeskommune og bokmåloversettere av OpenOffice.org. Den empiriske
4376 delen av oppgaven er delt inn i to seksjoner; den første omhandler
4377 operativsystemet Skolelinux, den andre kontorprogrampakken
4378 OpenOffice.org.
</p
>
4380 <p
>Som vi vil se gir GPL lokal frihet og kontroll gjennom omfordeling
4381 av makt fra produsent til bruker. Brukerens makt analyseres gjennom
4382 begrepene brukermedvirkning og handlingsfrihet. Det blir også lagt
4383 vekt på strukturelle forhold rundt bruken av teknologi, og spesielt de
4384 økonomiske begrepene nettverkseksternaliteter, innlåsing og
4385 stiavhengighet. Dette er begreper av spesiell nytte når objektet som
4386 omsettes eller distribueres er et kommunikasjonsprodukt, fordi verdien
4387 til et slikt gode for en potensiell bruker avhenger av antall
4388 eksisterende brukere av godet. I tilknytning til denne problematikken
4389 inneholder oppgaven også en diskusjon rundt åpne standarder og
4392 <p
>Oppgaven konkluderer med at de «fire frihetene» som GPL-lisensen er
4393 laget for å beskytte er av avgjørende betydning for bruken av
4394 OpenOffice.org og Skolelinux, i Akershus fylkeskommune såvel som i
4395 skolene i Nittedal. Distribusjonen av handlekraft er ikke helt
4396 symmetrisk. Det er først og fremst de profesjonelle utviklerne i
4397 Skolelinux som direkte kan nyttiggjøre seg friheten til å endre kode,
4398 mens en sluttbruker som Nittedal kommune nyttiggjør seg den økonomiske
4399 friheten til å kunne distribuere programmene. Det er imidlertid også
4400 slik at ingen aktør klarer seg uten alle disse «frihetene».

>Behind
<a href=
"http://www.skolelinux.org/
">Debian Edu and
4417 Skolelinux
</a
> there are a lot of people doing the hard work of
4418 setting together all the pieces. This time I present to you Andreas
4419 Mundt, who have been part of the technical development team several
4420 years. He was also a key contributor in getting GOsa and Kerberos set
4421 up in the recently released
4422 <a href=

4423 Edu Squeeze
</a
> version.

4425 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
4427 <p
>My name is Andreas Mundt, I grew up in south Germany. After
4428 studying Physics I spent several years at university doing research in
4429 Quantum Optics. After that I worked some years in an optics company.
4430 Finally I decided to turn over a new leaf in my life and started
4431 teaching
10 to
19 years old kids at school. I teach math, physics,
4432 information technology and science/technology.
</p
>
4434 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4435 project?
</strong
></p
>
4437 <p
>Already before I switched to teaching, I followed the Debian Edu
4438 project because of my interest in education and Debian. Within the
4439 qualification/training period for the teaching, I started
4440 contributing.
</p
>
4442 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4443 Edu?
</strong
></p
>
4445 <p
>The advantages of Debian Edu are the well known name, the
4446 out-of-the-box philosophy and of course the great free software of the
4447 Debian Project!
</p
>
4449 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
4450 Edu?
</strong
></p
>
4452 <p
>As every coin has two sides, the out-of-the-box philosophy has its
4453 downside, too. In my opinion, it is hard to modify and tweak the
4454 setup, if you need or want that. Further more, it is not easily
4455 possible to upgrade the system to a new release. It takes much too
4456 long after a Debian release to prepare the -Edu release, perhaps
4457 because the number of developers working on the core of the code is
4458 rather small and often busy elsewhere.
</p
>
4460 <p
>The
<a href=
"http://wiki.debian.org/DebianLAN
">Debian LAN
</a
>
4461 project might fill the use case of a more flexible system.
</p
>
4463 <p
><strong
>Which free software do you use daily?
</strong
></p
>
4465 <p
>I am only using non-free software if I am forced to and run Debian
4466 on all my machines. For documents I prefer LaTeX and PGF/TikZ, then
4467 mutt and iceweasel for email respectively web browsing. At school I
4468 have Arduino and Fritzing in use for a micro controller project.
</p
>
4470 <p
><strong
>Which strategy do you believe is the right one to use to
4471 get schools to use free software?
</strong
></p
>
4473 <p
>One of the major problems is the vendor lock-in from top to bottom:
4474 Especially in combination with ignorant government employees and
4475 politicians, this works out great for the
"market-leader
". The school
4476 administration here in Baden-Wuerttemberg is occupied by that vendor.
4477 Documents have to be prepared in non-free, proprietary formats. Even
4478 free browsers do not work for the school administration. Publishers
4479 of school books provide software only for proprietary platforms.
</p
>
4481 <p
>To change this, political work is very important. Parts of the
4482 political spectrum have become aware of the problem in the last years.
4483 However it takes quite some time and courageous politicians to
'free
'
4484 the system. There is currently some discussion about
"Open Data
" and
4485 "Free/Open Standards
". I am not sure if all the involved parties have
4486 a clue about the potential of these ideas, and probably only a
4487 fraction takes them seriously. However it might slowly make free
4488 software and the philosophy behind it more known and popular.

4554 <description><p
>Recently I have spent time with
4555 <a href=
"http://www.slxdrift.no/
">Skolelinux Drift AS
</a
> on speeding
4556 up a
<a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>
4557 Lenny installation using LTSP diskless workstations, and in the
4558 process I discovered something very surprising. The reason the KDE
4559 menu was responding slow when using it for the first time, was mostly
4560 due to the way KDE find application icons. I discovered that showing
4561 the Multimedia menu would cause more than
20 000 IP packages to be
4562 passed between the LTSP client and the NFS server. Most of these were
4564 NFS LOOKUP calls, resulting in a NFS3ERR_NOENT response. Because the
4565 ping times between the client and the server were in the range
2-
20
4566 ms, the menus would be very slow. Looking at the strace of kicker in
4567 Lenny (or plasma-desktop i Squeeze - same problem there), I see that
4568 the source of these NFS calls are access(
2) system calls for
4569 non-existing files. KDE can do hundreds of access(
2) calls to find
4570 one icon file. In my example, just finding the mplayer icon required
4571 around
230 access(
2) calls.
</p
>
4573 <p
>The KDE code seem to search for icons using a list of icon
4574 directories, and the list of possible directories is large. In
4575 (almost) each directory, it look for files ending in .png, .svgz, .svg
4576 and .xpm. The result is a very slow KDE menu when /usr/ is NFS
4577 mounted. Showing a single sub menu may result in thousands of NFS
4578 requests. I am not the first one to discover this. I found a
4579 <a href=
"https://bugs.kde.org/show_bug.cgi?id=
211416">KDE bug report
4580 from
2009</a
> about this problem, and it is still unsolved.
</p
>
4582 <p
>My solution to speed up the KDE menu was to create a package
4583 kde-icon-cache that upon installation will look at all .desktop files
4584 used to generate the KDE menu, find their icons, search the icon paths
4585 for the file that KDE will end up finding at run time, and copying the
4586 icon file to /var/lib/kde-icon-cache/. Finally, I add symlinks to
4587 these icon files in one of the first directories where KDE will look
4588 for them. This cut down the number of file accesses required to find
4589 one icon from several hundred to less than
5, and make the KDE menu
4590 almost instantaneous. I
'm not quite sure where to make the package
4591 publicly available, so for now it is only available on request.
</p
>
4593 <p
>The bug report mention that this do not only affect the KDE menu
4594 and icon handling, but also the login process. Not quite sure how to
4595 speed up that part without replacing NFS with for example NBD, and
4596 that is not really an option at the moment.

4626 Schweer, a valuable contributor to the project from Germany.
4628 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p

4630 <p
>I
've studied Mathematics at the university
'Ruhr-Universität
' in
4631 Bochum, Germany. Since
1981 I
'm working as a teacher at the school
4632 "<a href=
"http://www.westfalenkolleg-dortmund.de/
">Westfalen-Kolleg
4633 Dortmund
</a
>", a second chance school. Here, young adults is given
4634 the opportunity to get further education in order to do the school
4635 examination
'Abitur
', which will allow to study at a university. This
4636 second chance is of value for those who want a better job perspective
4637 or failed to get a higher school examination being teens.
</p
>
4639 <p
>Besides teaching I was involved in developing online courses for a
4640 blended learning project called
'abitur-online.nrw
' and in some other
4641 information technology related projects. For about ten years I
've been
4642 teacher and coordinator for the
'abitur-online
' project at my
4643 school. Being now in my early sixties, I
've decided to leave school at
4644 the end of April this year.
</p
>
4646 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4647 project?
</strong
></p
>
4649 <p
>The first information about Skolelinux must have come to my
4650 attention years ago and somehow related to LTSP (Linux Terminal Server
4651 Project). At school, we had set up a network at the beginning of
1997
4652 using Suse Linux on the desktop, replacing a Novell network. Since
4653 2002, we used old machines from the city council of Dortmund as thin
4654 clients (LTSP, later Ubuntu/Lessdisks) cause new hardware was out of
4655 reach. At home I
'm using Debian since years and - subscribed to the
4656 Debian news letter - heard from time to time about Skolelinux. About
4657 two years ago I proposed to replace the (somehow undocumented and only
4658 known to me) system at school by a well known Debian based system:
4659 Skolelinux.
</p
>
4661 <p
>Students and teachers appreciated the new system because of a
4662 better look and feel and an enhanced access to local media on thin
4663 clients. The possibility to alter and/or reset passwords using a GUI
4664 was welcomed, too. Being able to do administrative tasks using a GUI
4665 and to easily set up workstations using PXE was of very high value for
4666 the admin teachers.
</p
>
4668 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4669 Edu?
</strong
></p
>
4671 <p
>It
's open source, easy to set up, stable and flexible due to it
's
4672 Debian base. It integrates LTSP out-of-the-box. And it is documented!
4673 So it was a perfect choice.
</p
>
4675 <p
>Being open source, there are no license problems and so it
's
4676 possible to point teachers and students to programs like
4677 OpenOffice.org, ViewYourMind (mind mapping) and The Gimp. It
's of
4678 high value to be able to adapt parts of the system to special needs of
4679 a school and to choose where to get support for this.

4690 Annotator). At school (Skolelinux Lenny): Iceweasel, Gedit,
4691 LibreOffice.

4697 that doesn

4716 <p
>Det er store forskjeller på skolenes digitale tilstand, viser
4717 undersøkelsen Monitor
2011 som er laget på oppdrag fra
4718 Kunnskapsdepartementet. Dette har ført til debatt om PC-tilgangen i
4719 skolen, og om de med Linux i skolen gjør det bedre bedre eller
4720 dårligere enn snittet i landet.
</p
>
4722 <p
>Nå har vi tallene. Skoler med Linux har
36% større PC-tetthet en
4723 landsgjennomsnittet. På spørsmål hvorfor skoler med Linux har større
4724 PC-tetthet, observerer Paul Reidar Løsnesløkken som er IKT-konsulent i
4725 Nord-Odal:
</p

4727 <p
><blockquote
>"Vi erfarer at klienter med Skolelinux har god funksjon
4728 til de er
8 til
10 år gamle. Dette er omtrent dobbelt så lenge som
4729 andre løsninger, og skolene får mer datautstyr for
4730 pengene.
"</blockquote
></p
>
4732 <p
>Undersøkelsen baserer seg på
56 skoler som har gjort det offentlig
4733 at de kjører Skolelinux eller annen Linux-utgave. De kan også ha PC-er
4734 med Windows i skolenettet. Når en sammenligner PC-tetthetene på
4735 skolene i kommunene Flora, Harstad, Kongsvinger, Narvik, Nittedal,
4736 Nord-Odal og Randaberg, er det i snitt
2,
28 elev pr. PC på skolene med
4737 Linux. På landsbasis er det
3.11 elev per PC i grunnskolen, i følge
4738 side
95 i Monitor-rapporten for
2011. Målingen viser dermed
36% større
4739 PC-tetthet i skoler med Linux.

4743 <p
>Skolelinux har til hensikt å gi alle barn full tilgang til
4744 skoleaktuelle dataprogram på sitt eget morsmål. Derfor følger det med
4745 godt over
100 skoleaktuelle programmene laget for læring. De fleste
4746 programmene er oversatt til over
50 språk. Elevene skal også kunne
4747 studere alle sider av dataprogrammene. Derfor følger også kildekode
4748 med. Elever med interesse kan lære av eksperter som har laget
4749 systemet. Dette med enkelt programmering i læreprogram som KTurtle,
4750 til profesjonelle verktøy som Qt Creator eller Java.
</p

4752 <p
>Skolelinux er laget for sentralisert drift, der alt teknisk
4753 administrasjon av alle skolene kan gjøres sentralt fra kommunehuset
4754 eller sentralt i en region. F.eks. drifter to-tre personer
70.000
4755 skoledatamaskiner på
200 skoler i delstaten Extremadura i
4756 Spania. Etter velykket bruk av Debian Edu i skolen, legger delstaten
4757 over til Debian på
40.000 datamaskiner i administrasjonen. Det er idag
4758 mange selskap som tilbyr profesjonell støtte til innføring og drift i
4759 Norge og verden.

>I serien med intervjuer av folk i
4797 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet, får vi
4798 denne gangen høre fra en IKT-ansvarlig som har brukt Skolelinux i
4799 mange år, og vært storfornøyd med erfaringene så langt.
</p
>
4801 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
4803 <p
>Mitt navn er Roy-Arne Myhre og jeg er
42 år. Jeg er ansatt hos
4804 <a href=
"http://www.sandskole.no/
">Sand skole
</a
> (Balsfjord kommune)
4805 og har stort sett vært det siden
1990. Jeg er IKT ansvarlig ved
4806 skolen i
40% stilling –
10% undervisning – musikk.
</p
>
4808 <p
>Ved skolen er det ca
100 elever og ca
18 lærere +
4 assistenter i
4809 hele og delte stillinger. Alle lærerne har bærbar PC (dessverre med
4810 Win Vista) – assistenter har tilgang til egne. Vi benytter Fronter i
4811 det daglige arbeidet. Vi har ca
90 elevmaskiner som fungerer til
4812 daglig opp mot Linux server (XFCE) som driftes av
4813 <a href=
"http://www.bzz.no/
">BzzWare AS
</a
> via nett. Maskinparken
4814 består kun av brukt utstyr for elevene – og noe av dette begynner å
4815 bli vel gammelt selv som halvtykke klienter.
</p
>
4817 <p
><strong
>Hvordan kom du i kontakt med
4818 Skolelinux-prosjektet?
</strong
></p
>
4820 <p
>Vi kom første gang i kontakt med Skolelinux rundt
1997. Den gang
4821 var det oppstart-disketter i hver maskin, ikke mulighet for lyd og
4822 video, gamle nettverkskort og mye plundring. Vi hadde en ihuga
4823 forelder med som pådriver, forsker og inspirator for hele opplegget.
4824 Selv ante jeg knapt at Skolelinux fantes, men han var av den
4825 utforskende typen, og fikk både meg og skolelederen i trua på at dette
4826 var ting som kunne fungere. Etter dette har det gått gradvis
4827 framover; flere maskiner er hentet inn gjennom bl.a
4828 <a href=
"http://www.greentech.no/
">Greentech
</a
> og utrangert utstyr
4829 fra høgskole / Avinor og private givere. Når maskinene ble for trege
4830 for nye Windows-versjoner, sto vi klare til å putte dem i nettverket
4831 vårt. Dette betyr at vi i dag har
1:
1 dekning av maskiner på
4832 ungdomstrinnet og bedre enn
1:
2 på barnetrinnet. Dette er vi veldig
4833 fornøyd med, og vi kan ikke se for oss hverdagen som ville vært
4834 alternativet ved bruk av Windows med sine lisenser pr. Bruker/maskin.
4835 Da ville vi nok vært tilbake til
1-
2 maskiner pr klasserom med de
4836 negative konsekvenser det ville hatt for undervisningsformene våre. Vi
4837 kan ha en hel klasse i prosjektjobbing eller individuell jobbing
4838 samtidig – vi kan avholde tentamen og eksamen uten
4839 logistikkproblemer.
</p
>
4841 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
4843 Hvor skal jeg begynne... Stabiliteten er et nøkkelord - det bare
4844 virker. Har du først fått en server med Skolelinux opp og gå, så må
4845 det en maskinarefeil eller sabotasje til for å stoppe den. Det at man
4846 kan bruke eldre maskiner som normalt sett ville gått på dynga, er også
4847 glimrende - billig for skoler med dårlig økonomi og bra for miljøet
4848 siden vi gjenbruker utstyr i stedet for å skaffe nytt. Vi ville aldri
4849 hatt mulighet til å operere med det maskinantallet vi har pr i dag
4850 hvis det ikke var for Skolelinux - så tilgjengelighet er et annet
4851 nøkkelord. Et tredje moment er sikkerhet og brukertilgang. Alle
4852 brukerer opererer med egne brukernavn og passord, samt egne
4853 brukerområder som kan tilpasses for både enbrukertilgang og for
4854 samarbeid med andre.
4856 Elever har godt av å se at det finnes andre alternativer enn de som
4857 storindustrien selger på lisensbasis - på den måten trenes de opp til
4858 å se flere muligheter og å foreta valg ut fra flere opsjoner.
4860 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
4862 <p
>Ulempene med Skolelinux er nok utbredelsen og mangelen på kjennskap
4863 til dette i skolenorge. De som skal ta økonomiske avgjørelser rynker
4864 på nesen og vil gå for det kjente og «sikre» selv om det koster mye
4865 mer. Man får rett og slett litt hetta av å ikke kunne noe – og unngår
4866 dette for enhver pris.
</p
>
4868 <p
>I tillegg er mye av linux-systemet administrert av tekstkommandoer
4869 og er lite intuitiv/visuell for oss som ikke er «inne i»
4870 kildekodene». Så problemet er nok mye godt at de som
4871 utarbeider/drifter Skolelinux ikke helt klarer å sette seg ned på
4872 skoleadministratorens nivå når det gjelder problemer og
4873 utfordringer. Men dette er nok en utfordring alle administratorer
4874 sliter med uansett OS.
</p
>
4876 <p
>Derfor har vi valgt å støtte oss til BzzWare AS for assistanse i
4877 drifta slik at jeg har kunnet konsentrere meg mer om kabling, skifting
4878 av komponenter, veiledning av lærere og elever, vedlikehold av
4879 skrivere og annen daglig drift.
</p
>
4881 <p
>Elevene mestrer Skolelinux helt fint. Så lenge Internett
4882 (Iceweasel) og Libreoffice (Openoffice) fungerer er
90% av
4883 skolehverdagen velfungerende. I tillegg brukes jo en del av den
4884 pedagogiske programpakken bla. i forhold til matematikk og geografi,
4885 men det er såpass mye bra på nett om dagen, så disse programmene er
4886 mer som krydder å regne.
</p
>
4888 <p
>Jeg skulle ønske neste versjon av Skolelinux kunne komme litt
4889 mindre stappet med programmer, for halvparten blir aldri brukt, eller
4890 fungerer ikke uansett. Hva med et pedagogisk panel av lærere/IKT
4891 ansvarlige som kunne sagt: disse programmene skal være standard, så
4892 får resten være slike man kan legge til ved behov – det kan lett bli
4893 en jungel å bevege seg i.
</p
>
4895 <p
>Jeg ønsker meg også en mer grafisk versjon av
4896 <a href=
"http://bzz.no/lwat/trac/trac.cgi
">Lwat
</a
> hvor man kan krysse
4897 ut de som f.eks ikke skal ha internett-tilgang en dag pga
4898 eksamen/tentamen, samt en noe enklere brannmurløsning hvor man kan
4899 stenge for en del (få) sider på en enkel måte. Jeg liker godt
4900 Skolelinux sin ideologi om at filteret skal trenes i hodet på eleven –
4901 men av og til skulle jeg ønske at f.eks Facebook og Youtube kunne vært
4902 koblet vekk en periode for å få bedre utnyttelse av tid og
4903 ressurser. Disse to nettstedene er nok mye av årsaken til at mange
4904 lærere holder igjen databruken noe mer enn man kunne ønske.
</p
>
4906 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
4908 Jeg benytter nesten bare fri programvare til daglig. LibreOffice,
4909 Iceweasel (Firefox), Thunderbird til e-post og Gimp til
4910 bildebehandling. Vi har PHP-Nuke-oppsatt hjemmeside. Det eneste som
4911 jeg ikke har fått helt til enda er videoredigering - her må man vel
4912 innrømme at Mac er hakket over, men da er vi igjen over på å se hva
4913 som egner seg best, og ta valg ut fra det. Folk flest lever i
4914 villfarelsen om at regneark HETER Excel og tekstbehandling HETER
4915 Word. Dette er en misforståelse som jeg bruker mye energi på å
4916 diskutere og
"åpne sinn
" på Microsoft-slaver. Dessverre er det mange
4917 IKT-ansvarlige som også har låst seg på at det eneste saliggjørende er
4918 Bill G sine produkter.
4920 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
4921 skoler til å ta i bruk fri programvare?
</strong
></p
>
4923 <p
>For å komme lenger i utbredelsen av Skolelinux tror jeg det må mer
4924 fram i nasjonale medier, samt komme bedre fram hva økonomien i dette
4925 valget vil være – samt mulighetene. Fri programvare er en berikelse og
4926 gjør oss i stand til å utføre arbeidet i skolen uten å måtte legge
4927 igjen tusener på tusener i Bill Gates lomme.. Få ETT nettsted med
4928 forståelig veiledning av installasjon/oppgradering og ETT forum med
4929 konkrete feilrettinger og problemer, så tror jeg vi kunne kommet et
4930 par skritt framover. Ellers tror jeg bare at ildsjelene må fortsette å
4931 skinne – kanskje flere enn oss følger etter på veien.

>Den siste uka har det vært en del skriverier om hvor store
4966 forskjeller det er mellom skolene når det gjelder digital kompetanse.
4968 <a href=
"http://www.digi.no/
891660/bekymret-for-it-i-skolen
">oppslaget
4969 i Digi
</a
>. Diskusjonen fikk meg til å bli litt nysgjerrig på om
4970 Linux-skoler har større PC-tettet enn snittet i landet. Grunnlaget
4971 for diskusjonen har vært undersøkelsen
4972 <a href=
"https://iktsenteret.no/ressurser/monitor-
2011-skolens-digitale-tilstand
">Monitor
4973 2011</a
>, som bruker informasjon fra
4974 <a href=
"https://www.wis.no/gsi
">Grunnskolens Informasjonssystem
</a
>
4975 (GSI). GSI-data kan lastes ned fra web og jeg lastet ned en Excel-fil
4976 (intet åpen standard-valg tilgjengelig) med navn på alle skoler,
4977 hvilke kommune de befinner seg i og hvor mange elever pr. elev-PC de
4978 har rapportert inn. For å få en ide om svaret trenger jeg deretter å
4979 vite hvilke skoler i landet som bruker Linux, slik at jeg kan slå dem
4980 opp i GSI og finne ut hvor stor PC-tetthet de har.
</p
>
4982 <p
>Jeg vet om skoler i Balsfjord, Flora, Harstad, Kongsvinger, Narvik,
4983 Nittedal, Nord-Odal, Randaberg og Sunndal som bruker Skolelinux eller
4984 andre Linux-varianter. Jeg tror det er flere enn de
56 skolene jeg
4985 har klart å identifisere de siste dagene, men har ikke klart å få det
4986 bekreftet med offentlige kilder.
</p
>
4988 <p
>Monitor
2011-rapporteres side
95 forteller at det
"ifølge GSI
4989 (
20120-
2011) er det
3,
11 elever per datamaskin når vi tar med alle
4990 grunnskoler (
1.-
10.trinn)
". For de
56 Linux-skolene jeg har klart å
4991 koble mot informasjon i GSI er det
2,
28 elever per elevdatamaskin,
4992 hvilket betyr at det er
36% høyere PC-tetthet på Linux-skoler enn
4993 landsgjennomsnittet. Linux-skolen med høyest tettet blant de jeg har
4994 notert -skole er Flora ungdomsskule i Flora kommune med
0.82 elev
4995 pr. PC (
482 elever,
588 elevdatamaskiner).
</p
>
4997 <p
>Skolelinux gir datamaskiner lengre levetid, og en kan dermed få
4998 flere operative datamaskiner for samme budsjett, i tillegg til en
4999 rekke andre fordeler. Kan det være forklaringen på forskjellen?
</p
>
5001 <p
>Tallene må tas med en liten klype, da GSI ser ut til å ha endel
5002 feilføringer. Jeg synes i hvert fall en skole med
423 elever og
9
5003 elevmaskiner ser mistenkelig ut. Eller en skole med
346 elever,
0
5004 elevmaskiner, som er et annet ekstremt eksempel jeg fant.

</strong

5024 <p
>I teach ICT part time at the Rudolf Steiner School in Kings
5025 Langley, near London, UK. Previously I worked as a technical
5026 author/trainer while my children attended the school, and I also
5027 contributed to the Schoolforge UK community with the aim of
5028 encouraging UK schools to adopt free/open source software. Five or six
5029 years ago we had about
50 schools interested in some way, but we
5030 weren
't able to convert many of them into sustainable
5031 installations.
</p
>
5033 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5034 project?
</strong
></p
>
5036 <p
>Skolelinux had two representatives at an early Edubuntu meeting in
5037 London which I attended. However at that time our school network had
5038 just been installed using CentOS, LTSP
4 and GNOME. When LTSP
5 came
5039 along we switched to Edubuntu thin client servers so now we have a
5040 mixed environment which includes Windows PCs and student laptops, as
5041 well as their MacBooks and iPads. However, the proprietary systems
5042 have always been rather problematic, and we never built a GUI for the
5043 LDAP server, so when I discovered Skolelinux is configured for all
5044 these things we decided to try it.
</p
>
5046 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5047 Edu?
</strong
></p
>
5049 <p
>By far the biggest advantage is the Debian Edu community. Apart
5050 from that I have always believed in the same
"sustainable computing
"
5051 goals that Skolelinux is built on: installing Linux on computers which
5052 would otherwise be thrown away, to provide a reliable, secure and
5053 low-cost IT environment for schools. From my own experience I know
5054 that a part-time person can teach and manage a network of about
25
5055 Linux computers, but it would take much more of my time if we had
5056 proprietary software everywhere.

>
5058 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
5059 Edu?
</strong
></p
>
5061 <p
>As a newcomer I
'm just finding out who
's who in the community and
5062 how you
're organised, and what your procedures are for dealing with
5063 various things such as editing manual pages and so-on. The only
5064 English language mailing list seems to be for developers as well as
5065 users, so my inbox needs heavy pruning each day!
</p
>
5067 <p
><strong
>Which free software do you use daily?
</strong
></p
>
5069 <p
>Besides the software already mentioned at school we use Samba,
5070 OpenLDAP, CUPS, Nagios and Dansguardian for the network, and on the
5071 desktops we have LibreOffice, Firefox, GIMP and Inkscape. At home I
5072 use Ubuntu and an Android
4 eePad Transformer (but I
'm not sure if
5073 that counts...)
</p
>
5075 <p
><strong
>Which strategy do you believe is the right one to use to
5076 get schools to use free software?
</strong
></p
>
5078 <p
>That
's a tough question! For very many years UK schools installed
5079 and taught only proprietary software, so that at the highest levels
5080 the notion of
"computer
" means simply
"proprietary office
5081 applications
". However, schools today are experiencing budget
5082 constraints, and many are having to think hard about upgrading Windows
5083 XP. At the same time, we have students showing teachers how to use
5084 iPads, MacBooks and Android, so the choice of operating system is no
5085 longer quite so automatic. What is more, our government at last
5086 realised that we need people with programming skills, so they
're
5087 putting coding back in the curriculum! And it
's encouraging that the
5088 first
10,
000 Raspberry Pi units sold out in
2 hours.
</p
>
5090 <p
>I don
't really know what strategy is going to get UK schools to use
5091 free software, but building an active community of Skolelinux/Debian
5092 Edu users in this country has to be part of it.

>Documentation in Debian Edu is provided in several languages, and
5102 it is important to make it both easy to contribute and to keep the
5103 translated versions in sync. To do this we have come up with what we
5104 believe is a very efficient work flow.
</p
>
5108 <li
>The documentation is written in a
5109 <a href=
"http://moinmo.in
">moinmoin wiki
</a
> (see for example
5110 <a href=
"http://wiki.debian.org/DebianEdu/Documentation/Squeeze
">the
5111 Squeeze release manual
</a
>) with support for exporting the content as
5112 docbook XML.
</li
>
5114 <li
>This docbook document is given to po4a to extract a gettext style
5115 .pot file with the content, which in turn is used to create .po files
5116 with the translated text.
</li
>
5118 <li
>The .po files are given to translators, and they can always tell
5119 which part of the original wiki document is new or changed. They can
5120 use their normal translation tools like lokalize or poedit to write
5121 the translation. There is even a system in place to handle translated
5124 <li
>The translated .po files are combined with the original docbook
5125 XML document using po4a to create a translated docbook document.
</li
>
5127 <li
>The final step is to use all the generated docbook files and
5128 create PDF and HTML version of the original and translated documents.
</li
>
5132 <p
>This setup work very well, but have a few issues. The biggest
5133 issue is that
<a href=
"http://moinmo.in/DocBook
">the docbook support
5134 we use in moinmoin
</a
> is not actively maintained. The docbook
5135 support is also buggy, and our build system contain workarounds to
5136 make sure the generated docbook is usable despite these bugs.
</p
>
5138 <p
>If you want to have a look at our setup, it is all there in the

5195 <p
>Jeg hørte om det først når jeg jobbet i Redpill Linpro. Men jeg
5196 har også en datter som går på en friskole, som også bruker Skolelinux.
5197 Som kjent har ikke friskoler de samme økonomiske rammebetingelsene som
5198 offentlige skoler, så for dem var det det absolutt beste alternativet.
5199 De anser også Skolelinux som et stabilt system, som bare går og går (i
5200 motsetning til det lille Windows-baserte nettverket de har på
5201 admin-siden).

5206 lydløse og raskere arbeidsstasjoner som er bedre i klasserommet.
5207 Lengre levetid på PC

5208 så klart fjerning av alle lisenskostnader. Personlig synes jeg også at
5209 mange av programmene er bedre enn alternativene. Men dette er ofte en
5210 smakssak og avhengig om man må ha det man er vant til fra før.

5215 kompatibilitet med arbeidsstasjoners/bærbare maskiner sine
5216 nettverksdrivere eller skjermkort. Men dette løser vi i skolene ved
5217 standardisering. Ellers er det få, om nesten ingen, av de kjente
5218 maskinvare / infrastruktur leverandørene til fylkes- / kommuner som
5219 tilbyr denne plattformen. Skal dette endre seg så må kommunene selv
5220 sette slike krav til leverandørene.

5232 <p
>Fortsette å presentere flere av de gode eksemplene hvor Debian Edu
5233 / Skolelinux brukes i kommuner og enkeltskoler. Vi må få bedre frem
5234 at det er mulig tilknytte både Windows og Mac klienter på denne
5235 plattformen (selv om det vil øke driftskostnadene). Dette gjøres
5236 mange steder. Spesielt er det mange lærere som ønsker å bruke
5237 Windows/Mac-bærbare, gjerne som sin private PC også. Det er også mulig
5238 for kommunen å integrere med Active Directory i stedet for OpenLDAP
5239 som kommer med ut av boksen (selv om også dette øker kostnadene).
5240 Dette vil muligens bidra til å fjerne noe motstand hos noen
5241 potensielle brukere / driftpersonell for å ta i bruk noe
5242 nytt. Fremveksten av mobile brukere og nettbrett går i vår favør.
5243 Brukerne blir kjent og vant til flere nye operativsystemer /
5244 brukergrensesnitt. Så utviklerfellesskapet bør jobbe videre med å
5245 integrere flere nye klienttyper, som ultra lav-kostklienter og
5246 nettbrett (blant annet fri programvare-alternativet

>Inspired by
<a href=
"http://raphaelhertzog.com/tag/interview/
">the
5278 interview series
</a
> conducted by Raphael, I started a Norwegian
5279 interview series with people involved in the Debian Edu / Skolelinux
5280 community. This was so popular that I believe it is time to move to a
5281 more international audience.
</p
>
5283 <p
>While
<a href=
"http://www.skolelinux.org/
">Debian Edu and
5284 Skolelinux
</a
> originated in France and Norway, and have most users in
5285 Europe, there are users all around the globe. One of those far away
5286 from me is Nigel Barker, a long time Debian Edu system administrator
5287 and contributor. It is thanks to him that Debian Edu is adjusted to
5288 work out of the box in Japan. I got him to answer a few questions,
5289 and am happy to share the response with you. :)
5292 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
5294 <p
>My name is Nigel Barker, and I am British. I am married to Yumiko,
5295 and we have three lovely children, aged
15,
14 and
4(!) I am the IT
5296 Coordinator at Hiroshima International School, Japan. I am also a
5297 teacher, and in fact I spend most of my day teaching Mathematics,
5298 Science, IT, and Chemistry. I was originally a Chemistry teacher, but
5299 I have always had an interest in computers. Another teacher teaches
5300 primary school IT, but apart from that I am the only computer person,
5301 so that means I am the network manager, technician and webmaster,
5302 also, and I help people with their computer problems. I teach python
5303 to beginners in an after-school club. I am way too busy, so I really
5304 appreciate the simplicity of Skolelinux.
</p
>
5306 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5307 project?
</strong
></p
>
5309 <p
>In around
2004 or
5 I discovered the ltsp project, and set up a
5310 server in the IT lab. I wanted some way to connect it to our central
5311 samba server, which I was also quite poor at configuring. I discovered
5312 Edubuntu when it came out, but it didn
't really improve my setup. I
5313 did various desperate searches for things like
"school Linux server
"
5314 and ended up in a document called
"Drift
" something or other. Reading
5315 there it became clear that Skolelinux was going to solve all my
5316 problems in one go. I was very excited, but apprehensive, because my
5317 previous attempts to install Debian had ended in failure (I used
5318 Mandrake for everything - ltsp, samba, apache, mail, ns...). I
5319 downloaded a beta version, had some problems, so subscribed to the
5320 Debian Edu list for help. I have remained subscribed ever since, and
5321 my school has run a Skolelinux network since Sarge.
</p
>
5323 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5324 Edu?
</strong
></p
>
5326 <p
>For me the integrated setup. This is not just the server, or the
5327 workstation, or the ltsp. Its all of them, and its all configured
5328 ready to go. I read somewhere in the early documentation that it is
5329 designed to be setup and managed by the Maths or Science teacher, who
5330 doesn
't necessarily know much about computers, in a small Norwegian
5331 school. That describes me perfectly if you replace Norway with
5334 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
5335 Edu?
</strong
></p
>
5337 <p
>The desktop is fairly plain. If you compare it with Edubuntu, who
5338 have fun themes for children, or with distributions such as Mint, who
5339 make the desktop beautiful. They create a good impression on people
5340 who don
't need to understand how to use any of it, but who might be
5341 important to the school. School administrators or directors, for
5342 instance, or parents. Even kids. Debian itself usually has ugly
5343 default theme settings. It was my dream a few years back that some
5344 kind of integration would allow Edubuntu to do the desktop stuff and
5345 Debian Edu the servers, but now I realise how impossible that is. A
5346 second disadvantage is that if something goes wrong, or you need to
5347 customise something, then suddenly the level of expertise required
5348 multiplies. For example, backup wasn
't working properly in Lenny. It
5349 took me ages to learn how to set up my own server to do rsync backups.
5350 I am afraid of anything to do with ldap, but perhaps Gosa will
5353 <p
><strong
>Which free software do you use daily?
</strong
></p
>
5355 <p
>Nowadays I only use Debian on my personal computers. I have one for
5356 studio work (I play guitar and write songs), running AV Linux
5357 (customised Debian) a netbook running Squeeze, and a bigger laptop
5358 still running Skolelinux Lenny workstation. I have a Tjener in my
5359 house, that
's very useful for the family photos and music. At school
5360 the students only use Skolelinux. (Some teachers and the office still
5361 have windows). So that means we only use free software all day every
5362 day. Open office, The GIMP, Firefox/Iceweasel, VLC and Audacity are
5363 installed on every computer in school, irrespective of OS. We also
5364 have Koha on Debian for the library, and Apache, Moodle, b2evolution
5365 and Etomite on Debian for the www. The firewall is Untangle.
</p
>
5367 <p
><strong
>Which strategy do you believe is the right one to use to
5368 get schools to use free software?
</strong
></p
>
5370 <p
>Current trends are in our favour. Open source is big in industry,
5371 and ordinary people have heard of it. The spread of Android and the
5372 popularity of Apple have helped to weaken the impression that you have
5373 to have Microsoft on everything. People complain to me much less about
5374 file formats and Word than they did
5 years ago. The Edu aspect is
5375 also a selling point. This is all customised for schools. Where is the
5376 Windows-edu, or the Mac-edu? But of course the main attraction is
5377 budget.The trick is to convince people that the quality is not
5378 compromised when you stop paying and use free software instead. That
5379 is one reason why I say the desktop experience is a weakness. People
5380 are not impressed when their USB drive doesn
't work, or their browser
5381 doesn
't play flash, for example.

>Many years ago, the
<a href=
"http://www.skolelinux.org/
">Skolelinux
5428 / Debian Edu project
</a
> initiated a student project to create a tool
5429 for making stop motion movies. The proposal came from a teacher
5430 needing such tool on Skolelinux. The project, called
"stopmotion
",
5431 was manned by two extraordinary students and won a school award and a
5432 national aware with this great project. The project was initiated and
5433 mentored by Herman Robak, and manned by the students Bjørn Erik Nilsen
5434 and Fredrik Berg Kjølstad. They got in touch with people at Aardman
5435 Animation studio and received feedback on how professionals would like
5436 such stopmotion tool to work, and the end result was and is used by
5437 animators around the globe. But as is usual after studying, both got
5438 jobs and went elsewhere, and did not have time to properly tend to the
5439 project, and it has been lingering for a few years now. Until last
5442 <p
>Last year some of the users got together with Herman, and moved the
5443 project to Sourceforge and in effect restarted the project under a new
5445 <a href=
"http://sourceforge.net/projects/linuxstopmotion/
">linuxstopmotion
</a
>.
5446 The name change was done to make it possible to find the project using
5447 Internet search engines (try to search for
'stopmotion
' to see what I
5448 mean). I
've been following
5449 <a href=
"https://lists.sourceforge.net/lists/listinfo/linuxstopmotion-community

5528 <p
>Knut Yrvin her. Jobber i Nokia med å fremme rammeverket Qt og QML
5529 med tilhørende utviklerverktøy. Rollen er som leder av
5530 friprog-samfunn. I fjor var jeg med å legge om utviklingen av Qt til
5531 åpen forvaltning. På den måten kan alle som bidrar til Qt gjøre det
5532 på like vilkår. Nå er det

">over
5534 1000 utviklere
</a
> som bidrar til Qt. Med overgangen til åpen
5535 forvaltning er utviklingen av Qt mer åpen enn Linux-kjernen.
</p
>
5537 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
5539 <p
>Jeg var en av initiativtagerne til Skolelinux i
2001. Skolene slet
5540 med både utstyr og Internett-tilgang. De klarte ikke å møte
5541 forventningene til data i skolen. Driften av PC-ene var uholdbar. Som
5542 regel hadde rektor pekt ut en ivrig lærer til å passe på PC-ene,
5543 gjerne naturfaglæreren. Mange lærere jobbet mye ubetalt overtid for å
5544 vedlikeholde
30-
40 datamaskiner på hver sin skole. Med
300 elever og
5545 lærere som brukere, blir det fort mye mer arbeid enn de
4-
8 timene de
5546 kunne bruke på PC-drift. Skolene hadde kun en femtedel av
5547 IT-budsjettet som ble brukt på PC-ene i rådhuset.
</p
>
5549 <p
>Vi erfarte at skolene hadde mye datautstyr som stod ubrukt. Skolene
5550 manglet penger til Microsoft-lisenser. Selv med solide skolerabatter,
5551 kostet Microsoft-lisensene gjerne like mye som PC-ene i seg selv over
5552 en periode på
5-
6 år.
</p
>
5554 <p
>Viktigheten av språklig mangfold og pedagogiske programmer var også
5555 viktig for oss. Vi oversatte mange skoleaktuelle programmer til
5556 nynorsk, nordsamisk og bokmål. Dette lenge før andre tok denne
5557 oppgaven seriøst. Allerede etter ett år hadde vi etablert et helt
5558 arsenal av skoleaktuelle programmer på nynorsk, bokmål og
5559 nordsamisk. Vi spredde vår ide om språklig mangfold til de andre frie
5560 prosjekter internasjonalt. Resultatene ser vi i mange land. Det er de
5561 frie programmene som kommer på brukernes morsmål. Det er en av flere
5562 gode grunner til at fri programvare som LibreOffice, VLC, KDE og
5563 Firefox konkurrerer ut godseid programvare mange steder i verden.
</p
>
5565 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
5567 <p
>Fordelene er at Skolelinux tilbyr over
100 skoleaktuelle programmer
5568 på de norske språkene, uten ett øre i lisenskostnader. Systemet gir
5569 enormt lave driftskostnader med diskløse arbeidsstasjoner og bærbare
5570 med roaming. Skolelinux krever også mindre av maskinvaren.
</p
>
5572 <p
>Man kan fint kjøre systemet med
512 MB RAM på en bærbar PC sammen
5573 med en nettvideo i nettleseren og en presentasjon med
5574 LibreOffice. Konkurrerende system krever fort
2 GB RAM for å få til
5575 noe tilsvarende uten at det går ufattelig tregt. Skal man gjøre noe
5576 nyttig, krever konkurrentene til Linux mye større harddisk. Skoler har
5577 rapportert at de fort har fått
50% flere nye maskiner om de velger
5578 Linux. Dette i tillegg til de årlige besparelsene ved å unngå
5579 lisensbetaling til godseid programvare.
</p
>
5581 <p
>De lave driftskostnadene gjør at delstater i Europa har titusener
5582 av datamaskiner med Skolelinux i skolen. F.eks. er det under ti
5583 personer som drifter
70.000 PC-systemer i skolene i Extremadura i
5584 Spania. Det er slett ikke uvanlig at norske kommuner har
1500-
2000
5585 datamaskiner med Skolelinux. Driften tar ett årsverk. Slår flere
5586 kommuner seg sammen, kan de få samme sentraliserte stordriftsfordeler
5587 som delstater i Tyskland og Spania. Delstater som kjører Skolelinux
5588 på alle skolene. Bare noen få personer sentraldrifter titusenvis av
5591 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
5593 <p
>Den største ulempen for Skolelinux er motstand mot Linux fra
5594 IT-sjefer i det offentlige. Dette er ledere som holder innlegg som
5595 snytt ut av evangelist-håndboka til Microsoft. Dette gjøres i ett
5596 arbeidsmarked med stor vekst i etterspørselen etter Linux-fagfolk i
5597 privat sektor. Etterspørselen har økt mer enn noe annet tekniske yrke
5598 siste tiåret. Åtte av ti ledere vil ansette Linux-fagfolk i
2012,
5599 rapporterer jobbnettstedet Dice.com på oppdrag av Linux
5600 Foundation.
</p
>
5602 <p
>Det mangler
16.000 ingeniører og IKT-fagfolk i Norge rapporterte
5603 arbeids- og velferdsetaten NAV. Linux-fagfolk kan velge svært
5604 interessante jobber med alt fra apps på ledende mobilsystem laget med
5605 Linux, sky- tjenester eller web-applikasjoner. De raskest voksende
5606 teknologiselskapene i verden er ute etter Linux-fagfolk. Det være seg
5607 Amazon, Google, Facebook og IBM for å nevne noen. Linux er kritisk
5608 for å sikre veksten i markedet. Det sier seg selv at lønningene og
5609 jobbmulighetene er bedre enn for andre tekniske yrker.
</p
>
5611 <p
>Skal man lage apps for mobilen, smart-TV-en eller
5612 underholdningssystemet i bilen eller på flyet, er det Linux som
5613 gjelder. Med en slik konkurranse om Linux-kompetansen, kombinert med
5614 motstanden mot Linux hos mange IT-sjefer i offentlig sektor, så
5615 hindrer kommunene rekruttering av flere Linux- fagfolk. Skolene blir
5616 tvunget til å velge dyrere og mindre komplette IT-system. De har
5617 blitt hengende igjen slik IT var på begynnelsen av
2000- tallet. Dette
5618 fordi IT-ledere ikke har tilpasset seg markedet det siste tiåret.
</p
>
5620 <p
>Når det er sagt, er Skolelinux svært enkelt å lære seg også for de
5621 som ikke kan. Det viser alle lærerne som drifter systemet for
5622 hundrevis og tusenvis av systemer. Det meste er på plass rett ut av
5623 boksen. I tillegg er det solid med dokumentasjon med god hjelp på
5624 nettet. Det er mange kommuner som har ansatt en lærer som først lærte
5625 Skolelinux på sin skole, for så å drifte alle PC-ene i kommunen med
5626 Skolelinux. Det kan fort være snakk om
1000-
3000 datamaskiner på
10-
15
5627 skoler som sentraldriftes med en stilling. Står man ordentlig fast,
5628 kan man også kjøpe profesjonell hjelp fra selskap som støtter
5629 Skolelinux. Det er flere slike selskap i Norge og i utlandet.

5633 <p
>Qt SDK, LibreOffice, Firefox, VLC og KDE-skrivebordet. Dette på et
5634 Debian-basert GNU/Linux-system. Jeg bruker også noen morsomme
5635 3D-spill. Idag kan jeg velge mellom over
30.000 Linux-programmer. Det
5636 finnes ikke tid i livet å undersøke alle valgmulighetene. Derfor er
5637 det bra med Skolelinux i skolen, da utvalget av programmer er
5638 begrenset til hva som er aktuelt i skolefagene.
</p

5640 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
5641 skoler til å ta i bruk fri programvare?
</strong
></p

5643 <p
>Vi må selge hele Skolelinux forhåndsinstallert på maskinvare i hele
5644 pakker med
50-
100-
1000 PC-klienter med servere. Dette kan selges til
5645 enkeltskoler eller hele kommuner. Pakken må inneholde tjenermaskiner,
5646 svært rimelige diskløse arbeidsstasjoner, nettbrett med Plasma Active,
5647 og bærbare med roaming. Alt er godt testet med Debian. I et slikt
5648 anbud er det mulig å legge til sentraliserte drifts- og
5649 støttetjenester.
</p
>
5651 <p
>Man bør også selge sky-tjenester som læreadministrative systemet
5652 Moodle og driftsovervåking. I tillegg så bør man slenge seg på med
5653 presentasjoner de gangene LibreOffice og andre friprog-produkter
5654 selges til kommuner.

5693 stiftelsen Åpne kontorprogram på norsk for å oversette og teste den
5694 norske utgaven av OpenOffice.org. Arbeidet har hele tiden vært

5701 <p
>Skolelinux handler i likhet med utdanningssektoren om å dele
5702 kunnskap med andre, og det er dette som er hovedstyrken til
5703 prosjektet. Selv om Skolelinux hovedsaklig er involvert i utvikling
5704 av programvare, er det også et sted der man kan utfolde seg uavhengig
5705 av bakgrunn og ferdigheter.

5709 <p
>Liten utbredelse og manglende støtte fra leverandører som leverer

5711 verktøy som letter administrasjonen ytterligere, slik at også mindre

5719 hvis jeg skal dra fram noen flere eksempler så er nok Mozilla Firefox

5721 bruker av OpenSSH, Irssi, Midnight Commander, Git, Subversion,

>Vi må få leverandører av pedagogisk programvare med på laget, men
5729 også utvikle vår egen tilpasset det norske markedet. Det er også
5730 mulig å involvere utdanningssektoren direkte i arbeidet, for eksempel
5731 gjennom studentprosjekter der elevene selv er med å utforme
5732 programvare direkte eller indirekte gjennom aktive bidrag. Dette gjør
5733 ikke bare samarbeidet tettere, men fokuset på standarder og friheten
5734 til å velge sin egen løsning vil kanskje stimulere interessen for
5735 framtidig deltakelse i bransjen. Vi som driver med fri og åpen
5736 programvare ønsker oss ikke rene konsumenter, men tenkende og

">Debian Edu / Skolelinux
</a

5748 ability for clients to automatically configure their proxy settings
5749 based on their environment. We want all systems on the client to use
5750 the WPAD based proxy definition fetched from
<tt
>http://wpad/wpad.dat
</tt
>, to
5751 allow sites to control the proxy setting from a central place and make
5752 sure clients do not have hard coded proxy settings. The schools can
5753 change the global proxy setting by editing
5754 <tt
>tjener:/etc/debian-edu/www/wpad.dat
</tt
> and the change propagate
5755 to all Debian Edu clients in the network.
</p

5757 <p
>The problem is that some systems do not understand the WPAD system.
5758 In other words, how do one get from a WPAD file like this (this is a

5777 ftp_proxy=http://webcache:

5780 <p
>To do this conversion I developed a perl script that will execute
5781 the javascript fragment in the WPAD file and return the proxy that
5783 <tt
><a href=
"http://www.debian.org/

5784 and insert this extracted proxy URL in
<tt

5785 <tt

5786 fine in Squeeze, but in Wheezy the library it need to run the
5787 javascript code is
<a href=
"http://bugs.debian.org/
631045">no longer
5788 able to build
</a
> because the C library it depended on is now a C++
5789 library. I hope someone find a solution to that problem before Wheezy
5790 is frozen. An alternative would be for us to rewrite wpad-extract to
5791 use some other javascript library currently working in Wheezy, but no
5792 known alternative is known at the moment.
</p

5794 <p
>This automatic proxy system allow the roaming workstation (aka
5795 laptop) setup in Debian Edu/Squeeze to use the proxy when the laptop
5796 is connected to the backbone network in a Debian Edu setup, and to
5797 automatically use any proxy present and announced using the WPAD
5798 feature when it is connected to other networks. And if no proxy is
5799 announced, direct connections will be used instead.
</p
>
5801 <p
>Silently using a proxy announced on the network might be a privacy
5802 or security problem. But those controlling DHCP and DNS on a network
5803 could just as easily set up a transparent proxy, and force all HTTP
5804 and FTP connections to use a proxy anyway, so I consider that
5805 distinction to be academic. If you are afraid of using the wrong
5806 proxy, you should avoid connecting to the network in question in the
5807 first place. In Debian Edu, the proxy setup is updated using dhcp and
5808 ifupdown hooks, to make sure the configuration is updated every time
5809 the network setup changes.
</p

5863 var noen annen løsning. «Vandrende arbeidsstasjon» mener jeg ikke

5905 <description><p
>Since the Lenny version of
5906 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>, a
5907 feature to save power have been included. It is as simple as it is
5908 practical: Shut down unused clients at night, and turn them on again
5909 in the morning. This is done using the
5910 <a href=
"http://packages.qa.debian.org/s/shutdown-at-night.html
">shutdown-at-night
</a
> Debian package.
</p
>
5912 <p
>To enable this feature on a client, the machine need to be added to
5913 the netgroup shutdown-at-night-hosts. For Debian Edu, this is done in
5914 LDAP, and once this is in place, the machine in question will check
5915 every hour from
16:
00 until
06:
00 to see if the machine is unused, and
5916 shut it down if it is. If the hardware in question is supported by
5918 <a href=
"http://packages.qa.debian.org/n/nvram-wakeup.html
">nvram-wakeup
</a
>
5919 package, the BIOS is told to turn the machine back on around
07:
00 +-
5920 10 minutes. If this isn
't working, one can configure wake-on-lan to
5921 try to turn on the client. The wake-on-lan option is only documented
5922 and not enabled by default in Debian Edu.
</p
>
5924 <p
>It is important to not turn all machines on at once, as this can
5925 blow a fuse if several computers are connected to the same fuse like
5926 the common setup for a classroom. The nvram-wakeup method only work
5927 for machines with a functioning hardware/BIOS clock. I
've seen old
5928 machines where the BIOS battery were dead and the hardware clock were
5929 starting from
0 (or was it
1990?) every boot. If you have one of
5930 those, you have to turn on the computer manually.
</p
>
5932 <p
>The shutdown-at-night package is completely self contained, and can
5933 also be used outside the Debian Edu environment. For those without a
5934 central LDAP server with netgroups, one can instead touch the file
5935 <tt
>/etc/shutdown-at-night/shutdown-at-night
</tt
> to enable it.
5936 Perhaps you too can use it to save some power?

5946 publish the third beta version of
5947 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> based
5948 on Squeeze. If you want to test a LDAP backed Kerberos server with
5949 out of the box PXE configuration for running diskless machines and
5950 installing new machines, check it out. If you need a software
5951 solution for your school, check it out too. The full announcement is

"http://lists.debian.org/debian-edu-announce/

">available
</a
>
5953 on the project announcement list.
</p
>
5955 <p
>I am very happy to report these changes and improvements since
5956 beta2 (there are more, see announcement for full list):
</p
>
5960 <li
>It is now possible to change the pre-configured IP subnet from
5961 10.0.0.0/
8 to something else by using the subnet-change tool after
5962 the installation.
</li
>
5964 <li
>Too full partitions are now automatically extended on the Main
5965 Server, based on the rules specified in /etc/fsautoresizetab.
</li
>
5967 <li
>The CUPS queues are now automatically flushed every night, and all
5968 disabled queues are restarted every hour. This should cut down on
5969 the amount of manual administration needed for printers.
</li
>
5971 <li
>The set of initial users have been changed. Now a personal user
5972 for the local system administrator is created during installation
5973 instead of the previously created localadmin and super-admin users,
5974 and this user is granted administrative privileges using group
5975 membership. This reduces the number of passwords one need to keep
5976 up to date on the system.
</li
>
5980 <p
>The new main server seem to work so well that I am testing it as my
5981 private DNS/LDAP/Kerberos/PXE/LTSP server at home. I will use it look
5982 for issues we could fix to polish Debian Edu even further before the
5983 final Squeeze release is published.
</p
>
5985 <p
>Next weekend the project organise a
5986 <a href=

">developer
5987 gathering

5988 version, and start initial planning for the Wheezy version. Perhaps I

>With some computer hardware, one need non-free firmware blobs.
5999 This is the sad fact of todays computers. In the next version of
6000 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> based
6001 on Squeeze, we provide several scripts and modifications to make
6002 firmware blobs easier to handle. The common use case I run into is a
6003 laptop with a wireless network card requiring non-free firmware to
6004 work, but there are other use cases as well.
</p
>
6006 <p
>First and foremost, Debian Edu provide ISO images for DVD and CD
6007 with all firmware packages in the Debian sections main and non-free
6008 included, to ensure debian-installer find and can install all of them
6009 during installation. This take care firmware for network devices used
6010 by the installer when installing from from local media. But for
6011 example multimedia devices are not activated in the installer and are
6012 not taken care of by this.
</p
>
6014 <p
>For non-network devices, we provide the script
6015 <tt
>/usr/share/debian-edu-config/tools/auto-addfirmware
</tt
> which
6016 search through the
<tt
>dmesg
</tt
> output for drivers requesting extra
6017 firmware. The firmware file name is looked up in the Contents-ARCH.gz
6018 file available in the package repository, and the packages providing
6019 the requested firmware file(s) is installed. I have proposed to do
6020 something similar in debian-installer (BTS report
6021 <a href=
"http://bugs.debian.org/
655507">#
655507</a
>), to allow PXE
6022 installs of Debian to handle firmware installation better. Run the
6023 script as root from the command line to fetch and install the needed
6024 firmware packages.
</p
>
6026 <p
>Debian Edu provide PXE installation of Debian out of the box, and
6027 because some machines need firmware to get their network cards
6028 working, the installation initrd some times need extra firmware
6029 included to be able to install at all. To fill the PXE installation
6030 initrd with extra firmware, the
6031 <tt
>/usr/share/debian-edu-config/tools/pxe-addfirmware
</tt
> script is
6032 provided. Again, just run it as root on the command line to fill the
6033 PXE initrd with firmware packages.
</p
>
6035 <p
>Last, some LTSP clients might also need firmware to get their
6036 network cards working. For this,
6037 <tt
>/usr/share/debian-edu-config/tools/ltsp-addfirmware
</tt
> is
6038 provided to update the LTSP initrd with firmware blobs. It is used
6039 the same way as the other firmware related tools.
</p
>
6041 <p
>At the moment, we do not run any of these during installation. We
6042 do not know if this is acceptable for the local administrator to use
6043 non-free software, and it is their choice.
</p
>
6045 <p

>I serien med intervjuer av folk i
6156 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet, har jeg nå
6157 lyktes med å få tak i en skolemann som ikke er aktiv med utviklingen,
6158 men likevel har vært med nesten siden starten av prosjektet. Jeg
6159 ønsker derfor velkommen til Paul Reidar Løsnesløkken, en mann med
6160 mange års erfaring i bruk av Skolelinux.
</p
>
6162 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
6164 <p
>Jeg driftet tidligere IKT løsningen for skolene i
6165 <a href=
"http://www.nord-odal.kommune.no/
">Nord-Odal
</a
>. I dag er jeg
6166 IKT-konsulent for hele kommunen og samarbeider med
6167 <a href=
"http://www.hedmarken-ikt.no/
">Hedmark-IKT
</a
> for best mulig
6168 tjenester til kommunen. Jeg har bakgrunn som elektronikkreparatør og
6169 grunnskolelærer og har tatt en del fag innen IKT, i hovedsak
6170 driftsfag. IKT i Nord-Odal kommune blir i dag driftet av Hedmark IKT
6171 som er et samarbeid mellom Løten, Stange, Grue, Hamar, Kongsvinger og
6172 Nord-Odal. Jeg er fortsatt
"IKT-personen
" på skolene i kommunen og
6173 følger opp og gjør enkelte mindre endringer der.
</p
>
6175 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
6177 <p
>Kommunen satset på Skolelinux i
2004. Jeg var ikke med i
6178 beslutningsprosessen den gang, men ble likevel med fra starten når
6179 dette ble levert.
</p
>
6181 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6183 <p
>Fordelene med Skolelinux er rask oppstart, sentral drift av
6184 klientene, klienter som jobber raskt og effektivt, bedre
6185 funksjonalitet på eldre utstyr og en ganske god programpakke med fri
6186 programvare som følger med. Løsningen med halvtykke klienter gjør at
6187 prosessering skjer lokalt med alltid ferske maskiner.
</p
>
6189 <p
>Skolelinux kan fungere godt på gammelt utstyr, men det er klart at
6190 utstyr også blir for gammelt selv for Skolelinux. I forbindelese med
6191 at vi nylig fikk nye servere og ny installasjon kastet jeg ut ca
60
6192 klienter som fortsatt var i drift etter at de var kjøpt godt brukt i
6193 2004. Noe var rundt
15 år gammelt, men var fortsatt i bruk. Noen
6194 klaget på at det nå gikk veldig tregt på en del pedagogiske nettsider
6195 med flash o.l. Det er fullt forståelig.
</p
>
6197 <p
>Jeg fikk nylig et spørsmål fra ungdomsskolens rektor om jeg kunne
6198 legge inn
<a href=
"http://freemind.sourceforge.net/
">FreeMind
</a
>, et
6199 tankekartprogram , på skolens elev-Windowsmaskiner. Lærerne hadde
6200 vært på kurs og ville ta dette i bruk. Skolen har ca halvparten av
6201 elevmaskinene på bærbare Windowsmaskiner. Da kunne jeg fortelle at
6202 dette programmet allerede lå inne på den nye Skolelinuxløsningen
6203 som nettopp var satt i drift, klart til bruk.
</p
>
6205 <p
>Vi har de bærbare maskinene på ungdomsskolen i domene med
6206 Skolelinux. Dette fungerer også meget bra nå. Elevene får opp en
6207 midlertidig windowsprofil når de logger på. Denne profilen slettes
6208 etter at de logger av, noe som medfører rene profiler hver gang de
6209 starter opp en maskin. De må lagre i sin Skolelinprofil, noe som
6210 medfører at de får tak i sine filer uavhengig av om de starter en
6211 Windowsmaskin eller en Skolelinuxklient. Det er mye mindre trafikk i
6212 det trådløse nettet etter at ikke hele profiler blir lastet opp til de
6213 enkelte Windowsmaskinene og tilbake når man avslutter. Jeg vet ikke om
6214 dette er standardoppsett i Skolelinux, men slik er vårt oppsett
6217 <p
>Vi har i flere år satt opp vår løsning slik at skriverkøer slettes
6218 og skrivere startes hver natt. Hyggelig å høre at dette nå skal bli
6219 en standard i Skolelinuxløsningen. Dette har vært en god hjelp for
6222 <p
>Elevene er lite opptatt av om de jobber på en Skolelinux eller en
6223 Windowsmaskin bare de har de programmene de trenger og at det virker
6224 når det skal brukes. Vi kjører mest mulig de samme programmene på
6225 Windows som i Skolelinux, som f.eks Audacity og LibreOffice.
</p
>
6227 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6229 <p
>Lærere bruker hos oss Windows. Dette fordi de da selv har mer
6230 kontroll over sin maskin, kan bruke den overalt, og kan legge inn
6231 programmer selv når de trenger noe i forhold til kurs o.l de er
6232 på. Jeg tror lærernes selvstendighet her gjør dem tryggere på IKT-bruk
6233 generelt. Det at de av og til får opp advarsler og lignende gjør også
6234 at de må tenke igjennom og spørre om ting rundt datasikkerhet.
</p
>
6236 <p
>Det er en del programmer vi bruker som ikke finnes for Linux. Mest
6237 brukt er nok Photostory3 som brukes i mange sammenhenger, særlig på
6238 ungdomsskolen, bl.a. til å lage herbarier (plantesamling) . Dette
6239 finnes gratis for Windows, men er ikke fri programvare. Vi er opptatt
6240 av at programmer elevene bruker på skolen også kan brukes gratis
6241 hjemme. Det er også en del programmer som brukes til spesielle elever
6242 som bare går i Windows. Det er viktig med fokus på funksjoner og ikke
6243 på hvilket OS man bruker.
</p
>
6245 <p
>For oss er det kombinasjonen mellom Skolelinux og Windows som gir
6246 oss en god og hel løsning. Skolelinux er best der de er gode.
</p
>
6248 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
6250 <p
>Selv er det LibreOffice jeg bruker til daglig. Jeg bruker selv en
6251 Windowsmaskin. Jeg har benyttet en del fri programvare i forbindelse
6252 med sjekking av trafikk i nettverk, slik som Wireshark, men dette er
6253 jo ikke aktuelt for skolene. Jeg er generelt glad i programmer som
6254 fungerer på både Linux og Windows og gjerne MAC.
</p
>
6256 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
6257 skoler til å ta i bruk fri programvare?
</strong
></p
>
6259 <p
>Det er viktig at det benyttes programmer som elevene også kan ta i
6260 bruk hjemme. Det skal da være enkelt, lovlig og gratis for
6261 elevene. Da er jeg ikke lenger veldig opptatt av om det kalles
"fri
6262 programvare
". For skolene tror jeg
"gratis
" og
"funksjonelt
" er bedre
6263 begreper enn
"fri
" i forhold til programmer. De fleste skiller nok
6264 ikke mellom
"fri
" og
"gratis
". Det er nå svært mange elever som
6265 benytter OpenOffice eller LibreOffice som sin primære kontorpakke

>During christmas, I have been working getting the next version of
6322 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> ready
6323 for release. The initial problem I looked at was particularly
6324 interesting.
</p
>
6326 <P
>The installer would hang at the end when it was doing it
6327 post-installation configuration, and whatevery I did to try to find
6328 the cause and fix it always worked while I tested it, but never when I
6329 integrated it into the installer and ran the installation from
6330 scratch. I would try to restart processes, close file descriptors,
6331 remove or create files, and the installer would always unblock and
6332 wrap up its tasks.
</p
>
6334 <p
>Eventually the cause was found. The kernel was simply running out
6335 of entropy, causing the Kerberos setup to hang waiting for more.
6336 Pressing keys was adding entropy to the kernel, and thus all my tries
6337 to fix the problem worked not because what I was typing to fix it, but
6338 because I was typing.
</P
>
6340 <p
>The fix I implemented was to add a background process looking at
6341 the level of entropy in the kernel (by checking
6342 /proc/sys/kernel/random/entropy_avail), and if it was too small, the
6343 installer will flush the kernel file buffers and do
'find /
' to
6344 generate some disk IO. Disk IO generate entropy in the kernel, and is
6345 one of the few things that can be initated from within the system to
6346 generate entropy.

6365 Denne gangen har jeg besøk av et avtroppende styremedlem i
6366 <a href=

</strong

>
6371 <p
>Jeg heter Peter Hansteen, og jobber til daglig som seniorkonsulent
6372 i EDB ErgoGroup i Bergen. I praksis betyr det systemadministrasjon på
6373 Unix (primært Solaris, men en viss komponent av Linux). Men Solaris
6374 er for meg et relativt nytt bekjentskap, hovedplattformen min har
6375 generelt vært OpenBSD og til dels FreeBSD.

6377 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
6379 <p
>Jeg husker ikke helt alle detaljene mer ;) - men jeg tror det var
6380 gjennom news-gruppen no.it.os.unix.linux.diverse, efn-listen og
6381 etterhvert også BLUG-miljøet her i Bergen. Vi hadde et par
6382 Skolelinux-sentrerte BLUG-møter for noen år siden, og det har vært et
6383 par Skolelinux-utviklersamlinger her.
</p
>
6385 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6387 <p
>Jeg bruker dessverre ikke Skolelinux daglig. Men slik jeg kjenner
6388 prosjektet har det vært i stand til å ta opp i seg det beste av fri
6389 programvare i mange kategorier, så fra et sysadmin-perspektiv ser det
6390 ut som en svært behagelig sak. For brukerne er det vel både en fordel
6391 og en ulempe at det ikke er Windows. Men vi håper at fordelene med et
6392 fritt system etterhvert vil bli åpenbare for både elever, lærekrefter
6393 og foreldre.
</p
>
6395 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6397 <p
>Vel, ulempen er vel først og fremst at andre aktører med mer
6398 kapitalmuskel har klart å etablere seg som det både lærere og foreldre
6399 føler seg trygge på, selv om det etter mitt hode ikke er noen grunn
6400 til å være spesielt trygg på de kommersielle alternativene.
</p
>
6402 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
6404 <p
>Når jeg får bestemme helt selv, bruker jeg kun fri programvare. Da
6405 helst med vekt på ting som kjører greit på OpenBSD. Hjemme er det
6406 OpenBSD, Ubuntu eller FreeBSD vi bruker. På skrivebordet er det en
6407 avveining mellom Gnome, KDE eller hva-det-nå-heter som er
6408 standardvalget i Ubuntu, ellers er det de kjente tingene som
6409 LibreOffice, Emacs, mplayer. På server er det selvfølgelig Apache,
6410 for overvåking både OpenNMS og Nagios (det bare ble sånn, og
6411 forskjellige siter). Jeg skriver til tider om slikt jeg holder på med
6413 <a href=
"http://bsdly.blogspot.com
">http://bsdly.blogspot.com
</a
>.
</p
>
6415 <p
>Men vi må nevne at selv vi har en Microsoft-ting som vi slår på når
6416 vi av en eller annen grunn må. Det betyr igjen vanligvis når en
6417 mobiltelefon eller en annen lukket elektronisk dings krever kontakt
6418 via en slik for å få oppdateringene sine.
</p
>
6420 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
6421 skoler til å ta i bruk fri programvare?
</strong
></p
>
6423 <p
>Hadde vi hatt det rette svaret på det spørsmålet, så hadde vi
6424 gjerne hatt Skolelinux som førstevalg på alle skoler ;)
</p
>
6426 <p
>Men jeg tror vi må legge vekt på flere forskjellige ting. En helt
6427 sentral sak er å fokusere på fri programvare og åpne standarder som de
6428 demokratiske verdiene de faktisk er. Det har kanskje kommet litt for
6429 mye i bakgrunnen i forhold til strevet etter å lage det mest mulig
6430 'brukervennlige
' systemet. Det er en tung vei å gå, så det er
6431 forståelig at freenix-aktivister heller velger å skrive kode og annet
6432 som er mer lystbetont. Mer praktisk tror jeg vi må gjøre i alle fall
6433 to ting: For det første sørge for å fortsette med å levere det best
6434 mulige frie produktet, slik at det er lett å både komme i gang og
6435 holde systemene i daglig drift, og for det andre
2) spore opp mulige
6436 aktivister der de finnes, via lokale brukergrupper, sosiale medier
6437 eller annet og sørge for at de fortsetter å være aktive. Mer og
6438 mindre uformelle treff kan være nyttig i tillegg til de mer
6439 organiserte møtene med foredrag, konferanser og utviklersamlinger.

6468 <p
><strong

6470 <p
>Fordelene slik jeg ser det er den sentraliserte driftmodellen, og
6471 alle de vel gjennomtenkte løsningene som er inkludert i denne
6472 løsningen. Samtidig er det basert på en stabil, og godt kjent
6473 plattform. Dette vil si at man har en løsning som skal være mye
6474 tilgjengelig, og hvor det er relativt enkelt å få tak i personer som
6475 kan mye om den grunnleggende plattformen.

6477 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6479 <p
>De største utfordringene med en løsningen er at den er intensiv på f.eks
6480 nettverk. I seg selv ikke et problem for en enkelt skole, men skal løsningen
6481 kjøres i større skala, med sentraliserte servere, så gir dette noen
6482 utfordringer.
</p
>
6484 <p
>Utifra hva jeg har sett på større installasjoner så er det ikke så
6485 enkelt å skjønne, hva som bør gjøres for at den skal skaleres opp, og
6486 da ta godt vare på alle sider av dette, ikke bare mer server å fordele
6487 last/trykk, men hvordan også beholde robustheten og fleksibiliteten i
6488 løsningen.
</p
>
6490 <p
>En annen utfordring er at stadig flere produkter som skal brukes i
6491 skoleløsningen ikke er laget til å kunne brukes i en
6492 skolelinuxløsning. Det blir derfor fort mye skreddersøm i de
6493 forskjellige installasjonene, for å få diverse pedagogiske programmer,
6494 webløsninger, smartboards, m.m. til å fungere. Man er også en for
6495 liten kundebase til at leverandørene ønsker å gjøre noe med
6496 utfordringen. Problemet overlates til oss.
</p
>
6498 <p
>Det er også en kontinuerlig utfordring rundt problemet med å holde
6499 programvare på stabile versjoner, kontra å få ny funksjonalitet. Dette
6500 er jo en konflikt mellom oss som ønsker å drifte en stabil, og
6501 kostnadseffektiv løsning, mot sluttbrukerne som ønsker seg funksjoner
6502 det er vant med fra andre løsninger, eller som de må ha for at et
6503 eller annet nytt produkt skal fungere i løsningen. Dette er en
6504 utfordring også for andre plattformer.
</p
>
6506 <p
>En siste utfordring som ikke har noe med løsningen å gjøre, men med
6507 det omkringliggende miljøet denne skal kjøre i, er at de enhetene som
6508 skal drifte dataløsninger for kommuner og fylkeskommuner begynner å
6509 profesjonaliseres, og er da avhengig av å ha standard løsninger for å
6510 drifte store brukermasser. MS er selvsagt klar over dette, og har jo
6511 nå flere områder de begynner å bli veldig dominerende på. Den største,
6512 og mest problematiske er katalogtjenesten. Man får snart ikke tak i
6513 større løsninger som ikke krever en AD. Når man da har store enheter
6514 som drifter både kommunalt ansatte og skoler, så vil det være et
6515 stordriftargument å standardisere på en katalog tjeneste, og da har
6516 man ikke noe valg. Her er alle slike driftsenheter for små til å få
6517 gjort om på dette. Her burde konkurransemyndighetene kommet på
6518 banen. Men konkurransetilsynet i USA griper sjeldent (og ikke før det
6519 har gått veldig lang tid) inn i monopolsituasjoner så lenge
6520 monopolisten er et amerikansk firma, så da har vel ikke andre
6521 myndigheter så mye de skulle ha sagt....

</strong

6525 <p
>Privat kjører jeg Debian på alle mine datamaskiner. Det gjør jeg
6526 også på min jobbmaskin. Vi har også
15-
20 linux servere av typene
6527 SuSE, Debian, Redhat, CentOS m.m. Jeg bruker derfor mye fri
6528 programvare. Av enkelt programmer kan sikkert masse nevnes. Hvis vi
6529 skal begrense oss til daglig, så må jeg si: OpenOffice, Firefox,
6530 Kontact, Kopete, Amarok,
6531 <a href=
"http://gramps-project.org/
">Gramps
</a

6532 rsync, backuppc m.m.

6534 <p

>Hvilken strategi tror du er den rette å bruke for å få
6535 skoler til å ta i bruk fri programvare?
</strong
></p
>
6537 <p
>Det er et godt spørsmål, som jeg har lurt på selv.
</p
>
6539 <p
>Argumentene som ofte har vært brukt om at ting koster mindre holder
6540 ikke mål når man ser på hva som faktisk koster penger. Det er de
6541 ansatte som er en kostnadsdriver. Det vil si at hvis man har et system
6542 som den ansatte kan, så vil en kostnad på dette systemet kunne
6543 forsvares ganske mye ved at den ansatte gjør dette raskere og
6544 effektivt. Også uten å måtte eventuelt leie inn folk.
</p
>
6546 <p
>Jeg syns det er viktigere å fokusere på prinsippet med å velge fri
6547 programvare, men det er også et felt hvor man fort møter lite
6548 forståelse blant de ansatte i skolen.
</p
>
6550 <p
>Her må nok strategien fortsette å være at de sentrale myndighetene
6551 må sende tydelige signaler for hva de ønsker at offentlige enheter
6552 skal gjøre. Det var mye positivt på gang ang. dette for et par år
6553 siden. Både med eNorge og eKommune planene, men dette syns jeg har
6554 stoppet opp. En del av dette kan jo kanskje være usikkerheten som
6555 etter hvert har blitt, når man har sett kompleksiteten i de
6556 prosjektene som har blitt igangsatt. Det har også blitt noe usikkerhet
6557 i markedet ref. Sun, Oracle, Novell, Microsoft m.m. Samtidig har jo
6558 også de proprietære programleverandørene sørget for å endre sine
6559 lisenser slik at man uansett ikke slipper unna kostnaden til deres
6560 produkter, selv om man skulle velge alternativer. Da er det økonomiske
6561 argumentet, som jeg nevnte tidligere, spilt ganske godt ut over
6562 sidelinjen.

6586 hadde vel hørt om prosjektet i media før en gjeng i Trondheim startet
6587 opp SPIST, Skolelinux-prosjektet i Sør-Trøndelag, hvor vi hjalp noen
6588 skoler i nærområdet med å installere Skolelinux og finne brukt
6589 IT-utstyr til disse. Det var moro å gjøre noe praktisk for å spre
6590 Skolelinux, og å se hvor fort gjort det var å sette opp utrangerte
6591 klientmaskiner og få disse opp som tynnklienter på helt nye datasaler
6592 på skolene, kun med kostnaden til servere.

6596 <p
>Det er et system spesielt skreddersydd for drift av et stort antall

6598 er enkelt og billig å installere og drifte, og det trenger ikke ny
6599 maskinvare for god ytelse.

6603 <p
>Hardwarestøtten kunne vært bedre og i enda større grad
6604 installerbart rett ut av boksen. Distribusjonen har til tider hatt
6605 litt gammel programvare pga. at den følger Debian sine utgivelser.
6606 Kanskje man skulle vurdert en versjon basert på Ubuntu eller andre

6614 Telefonen min er en Android, og der bruker jeg programmene K-

6615 OI Shopping list, Shuffle, ZXing, OI Notepad og ADW Desktop. På jobb
6616 bruker jeg JBoss, Eclipse, uCLinux for Blackfin, RCF-CPP, Qt, Maven,

>En bør fokusere på totalkostnader inkludert driftsbehov,
6623 fleksibilitet, åpenhet og ikke låsing til en leverandør framfor sparte
6624 lisenskostnader, samt programvarens kvalitet og fortrinn, og at den
6625 fritt kan brukes på et ubegrenset antall PC-er, også hjemme hos
6626 elevene. En bør også forbedre den fri programvaren ved testing,
6627 bugrapportering og kodebidrag om man kan, og ikke anbefale programvare
6628 uten at man har forsikret seg at den har tilstrekkelig kvalitet,
6629 ellers kan man lett oppnå det motsatte. Tror en bør selge inn
6630 konseptet til fylkes-/statsnivå, kanskje med bidrag til
6631 utviklingsarbeid fra disse som alle landets skoler kan få glede

>Mine bloggposter om Linux i skolene i Norge førte til at inspektør
6642 og ildsjel på Harestad skole tok kontakt og fortalte at de bruker
6643 Linux på sin skole, og lurte på om de kunne bidra til å gjøre
6644 fordelene kjent. Riktig nok bruker de ikke
6645 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
> på denne skolen,
6646 men jeg synes dette er en god anledning til å gjøre flere fasetter
6647 rundt Linux-økosystemet kjent, og tok et lite intervju.
</p
>
6649 <p
><strong

6651 <p
>Mitt navn er Odin Hetland Nøsen og er en
70-modell. Jeg er bosatt i
6652 Stavanger og jobber nå på
9. året som undervisninginspektør på
6653 Harestad skole i Randaberg kommune (nabokommune til Stavanger).
</p
>
6655 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
6657 <p
>I
2002 begynte daværende IKT-ansvarlige og jeg et arbeid på skolen
6658 med å gå over fra Win98 til... noe annet. Vi testet en rekke
6659 forskjellige løsninger, deriblant Skolelinux, men endte opp med
6660 RedHat. Skolelinux var den gang ikke modent for det vi ville ha. Jeg
6661 har siden fulgt jevnlig med på hva skolelinux holder på med, men har
6662 hele tiden vært bedre fornøyd med vår egen
"standardiserte
" løsning på
6663 RedHat/CentOS og Fedora. Vi snuser for tiden på Ubuntu som løsning på
6664 klientsiden.
</p
>
6666 <p
>I dag har vi på skolen vår en større linux-løsning med
400 klienter
6667 som kjører en blanding av LTSP (tynnklient) og DRBL (tykk klient uten
6668 harddisk) med en masse tjenere på serverrommet. Vi drifter hele
6669 sulamitten selv med webtjener, eposttjener, webmail, filtjenere,
6670 virtuelle tjenere osv. Og IT-ansvarlig har en
80% stilling som
6671 IT-ansvarlig - og så er han KoH-lærer i de resterende
20% :-)
</p
>
6673 <p
>Du kan få en ide om hva vi holder på med om du går inn på
6674 <a href=
"http://www.gnuskole.no/
">http://www.gnuskole.no/
</a
>.
</p
>
6676 <p
>For å ta brodden av frykten for at ildsjeler gjør skolen sårbar om
6677 ildsjelene falle fra, har jeg forsikret kommunen og skolesjefen i
6678 Randaberg om at det finnes godt kommersielle tjenester vi kan benytte
6679 oss av - om det skulle bli nødvendig. Vi er tre stykker i kommunen som
6680 nå har
<strong
>god
</strong
> linux-kompetanse ift. å drifte et større
6681 system. IT-avdelingen i kommunen vil ikke ta på oss med ildtang -
6682 selv om vi nok har større IT-kompetanse mot linux enn det de selv har
6683 mot windows (de kjøper en
<strong
>masse
</strong
> konsulenttjenester
6684 fra ErgoGroup).
</p
>
6686 <p
>I kvantitet er Harestad og Grødem skole tilsammen et større
6687 IT-system enn resten av Randaberg kommune + Kvitsøy og Rennesøy, som
6688 kommunen også har driftsansvar for. Vi har som sagt rundt
800
6689 maskiner, mens kommunen med sitt driftsansvar har ansvar for rundt
500
6690 maskiner. Det er selvfølgelig litt forskjell i hvor kritiske
6691 tjenestene våre er, men det gir allikevel et litt rart bilde når
6692 IT-avdelingen overhode ikke er interessert i å snakke med oss om
6693 hvordan vi gjør ting :-)
</p
>
6695 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6697 <p
>Fra linux-perspektivet (ikke bare Skolelinux) er det en fordel av
6698 systemet er basert på fri programvare - og dermed fritt i ordets mange
6699 betydninger. Det er alt vi trenger: stabilt, relativt enkelt å drifte
6700 (tross alt - et større windowssystem er ikke enkelt å holde live det
6701 heller), rimelig i innkjøp og drift, og sist, men ikke minst, det er
6702 moderne for sluttbruker! Linux, i sine mange varianter,
6703 <strong
>ser
</strong
> nytt ut, fordi det hele tiden blir
6704 oppdatert. Derfor lever systemet opp til hvordan elever forventer at
6705 et moderne GUI skal være (i motsetning til WinXP :-).
</p
>
6707 <p
>Vi var veldig pragmatiske da vi begynte med linux i skolen. Det var
6708 billig, det fungerte og kunne bruke alle de gamle windows-maskinene
6709 som
"nye
" tynne klienter. I dag er vi mer bevisste fri
6710 programvare-tilhengere. Vi har oppdaget hva det er - og vi liker
6713 <p
>En av de
<strong
>store
</strong
> fordelene med fri programvare er at
6714 vi kan installere tjenester vi ønsker å tilby brukerne våre - uten å
6715 måtte tenke på om vi har råd til lisensene (fordi det er ingen). Alt
6716 vi setter i produksjon er ut i fra brukernes behov og vår kapasitet
6717 til å drifte dem. Vi skreddersyr tjenestene etter behovet og dermed
6718 trenger vi ikke ende opp med å kjøpe en pakke der vi egentlig bare var
6719 interessert i en liten del av den.
</p
>
6721 <p
>Bruk av linux frigjør ikke økonomiske midler, fordi midlene til IKT
6722 i skole er for få i utgangspunktet - men vi får så
6723 <strong
>mye
</strong
> mer igjen for dem når vi bruker en linux-løsning
6724 fremfor en windows-løsning. I praksis ser vi at vi måtte ut med det
6725 dobbelte på budsjettet vårt om vi skulle hatt en tilsvarende
6726 windows-løsning, som det vi i dag drifter med linux.
</p

6728 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6730 <p
>Ikke all pedagogisk programvare er tilgjengelig. Det er en del
6731 programvare i skolen som er laget med utviklerverktøy som bare virker
6732 i windows, f.eks. Drillpro, LingDys/LingWrite. Det er også
6733 "programmer
" som bare virker om du har tilgang til Microsoft Office,
6734 f.eks. AskiRaski.
</p
>
6736 <p
>Vi sliter også litt med at video-codecer ikke alltid er like lett å
6737 få opp å gå på klientene. Det er alltid en eller annen videosnutt fra
6738 nrk.no som ikke er så samarbeidsvillig, uansett mediaplayer.
</p
>
6740 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
6742 <p
>Alt :-) På skolen bruker vi det som finnes og som er nyttig. Det vi
6743 bruker mest er Firefox (jobber med Chrome, fordi det er
6744 <strong
>mye
</strong
> raskere med Flash enn Firefox), OpenOffice (skal
6745 over til LibreOffice), GIMP osv. Standardpakken av
6746 sluttbrukerprogrammer.
</p
>
6748 <p
>På tjenernivå bruker vi OpenWebMail (skal over til Zimbra), Exim
6751 <p
>Personlig bruker jeg de fleste programmer over flere plattformer,
6752 men jeg har lagt meg til en vane å prioritere bruken av fri
6753 programvare også i Windows
7 og OSX.

6755 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
6756 skoler til å ta i bruk fri programvare?
</strong
></p
>
6758 <p
>Jeg er langt i fra sikker. For det første handler det mye om at
6759 IKT-avdelingen i kommunen ofte er de som styrer hva som er IKT på
6760 skolene - og de liker å bruke avtalene med Microsoft, som de garantert
6761 har fra før. Dessuten - Select
6-avtalen til skolene gjør Microsoft
6762 skvettbillig.
</p
>
6764 <p
>Vi la vekt på effektiv drift av systemet - og at vi kunne øke
6765 antall maskiner uten å måtte øke budsjett for utstyr eller personell
6766 særlig mye, enn om vi hadde gått for en Microsoft-løsning. I praksis
6767 ser vi at en ren linux-installasjon driftes til halve prisen av en
6768 Microsoft-løsning.
</p
>
6770 <p
>Vi har i praksis også sett at det lærerne (og elevene) liker er at
6771 vi tilbyr
<strong
>veldig
</strong
> mange tjenester som ikke er så
6772 vanlige i en Microsoft-løsning. Det er ikke så vanlig at
6773 <strong
>elevene
</strong

6774 også brukt som et vellykket argument mot Microsoft.
</p
>
6776 <p
>Den beste måten er selvfølgelig at noen bare bestemmer
6777 det. Problemet er å få dem som har makt til å bestemme det til faktisk
6778 å gjøre det ;-)

6870 forkjærlighet for fri programvare har gjort at jeg har nå flere års
6871 erfaring med salg av slike løsninger (bl.a. fra Redpill Linpro og
6872 Freecode) og mye innsikt og kunnskap om det globale IT-markedet.
6873 Ellers er jeg involvert i flere prosjekter bl.a. er jeg Ubuntu
6874 Community medlem, kontaktpersonen for Ubuntu Norge og driveren av
6875 SpreadUbuntu marketing prosjektet og nå fersk styremedlem i FRISK. Jeg
6876 har brukt GNU/Linux siden
1997.

>Fri programvare bygges sten for sten i det åpne, slik at koden og
6888 prosessen den lages på kan gjennomskues av andre enn de som har laget
6889 det. Det er et vitenskapelig og gjennomsiktig måte å lage programvare
6892 <p
>Skoler i vårt samfunn skal være steder hvor vitenskapelig kunnskap
6893 deles til alle. I dag har vi ikke et vitenskapelig tilnærming til
6894 hvordan programvaren som brukes på skolen lages. Skolelinux bringer
6895 inn at slik tilnærming i skoleverkets klasserom, siden
6896 operativsystemet er en åpent platform som gir skolene muligheten til å
6897 dra nytte av programvare som er laget av tusenvis av mennesker verden
6898 rundt og som gir elevene så vel som lærerne muligheten til å bruke,
6899 dele, forandre og forbedre OSet sitt uten begrensninger. I den
6900 forbindelsen representerer Skolelinux også konkrete resultater utfra
6901 samhandling på tvers av grenser.
</p

6903 <p
>Når det gjelder de tekniske fordelene av Skolelinux er jeg sikker
6904 på at andre enn meg har allerede beskrevet disse bedre enn det jeg
6905 kan. Men jeg kan likevel tilføye noe: Skolelinux som sådan er en
6906 community-drevet operativsystemplatform. Som i ethvert
6907 community-prosjekt har alle Skolelinux brukere muligheten til å
6908 påvirke retning av prosjektet og resultatet som gjenspeiles i
6909 programvaren. Dette kommer sjeldent frem og jeg mener at det er noe
6910 som burde fokuseres mer på.

6923 <p

6973 <p
>Jeg husker en leverandør av et stort OS for noen år siden mente at

6975 kunne ta dette i bruk. Heldigvis er kunnskapen større nå og
6976 skikkelige

6986 <p
>Det største hinderet er det vi opplever på andre områder rundt
6987 fri programvare, nemlig kunnskap. For mange er det trygt å velge det vi
6988 alltid har valgt. Fordi leverandørene rundt oss sitter på den kunnskapen og
6989 de vi støtter oss på har den samme. Hvis vi klarer å riste løs litt og
6990 glemme gamle kriger mellom operativsystemer og leverandører, men sette ned
6991 hva som er viktig og velge ut fra det, så hadde man kanskje kommet ut med
6992 litt andre resultat. Jeg tror IT-folk er konservative og velger tradisjonelt
6993 og det er synd.

7000 skyen og setter pris på alt jeg slipper egen klient til. Derfor er
7001 jeg veldig sjarmert av små kjappe operativsystemer som krever minimalt
7002 av maskinvaren.

7008 sikkerhet, oppetid og åpne standarder. Informasjon om muligheter og

7010 å gå sammen. Det er til slutt LÆRING det dreier seg om, og da må man

>Sturle Sunde, ansvarleg for skulenettet i Flora kommune. Eg driv,
7029 vidareutviklar og er andrelinje brukarstøtte for datanettet ved
7030 skulane i Flora kommune.
10 skular og meir enn
700 maskiner med
7031 Linux, medrekna tynnklientar. Tidlegare jobba eg i mange år med
7032 unix-drift ved Universitetets senter for informasjonsteknologi ved
7033 Universitetet i Oslo.

7035 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p

7037 <p
>Det er vanskeleg å svare konkret på. Eg har drive med Unix og Linux i
7038 alle år, og Skulelinux er eit godt kjent prosjekt i miljøet. Det var
7039 først i
2008, då eg tok til i min noverande jobb, at eg fekk bruk for
7040 Skulelinux for alvor.
</p
>
7042 <p
>Jobben min skulle vere drift av eit nytt skulenett i Flora kommune,
7043 levert av eit firma eg ikkje vil reklamere for. Systemet skulle vere
7044 ferdig levert i september året før. Dette viste seg å ta mykje lenger
7045 tid, og i haustferien
2008 hadde dei endå ikkje klart å få opp ei
7046 fungerande løysing. Situasjonen var prekær for den største skulen i
7047 kommunen med meir enn
500 elevar på ungdomssteget. Skulen hadde brukt
7048 Skulelinux før, og var tilfredse med det. No hadde dei vore utan
7049 fungerande datasystem i nesten eit år. Difor fekk eg opp ein ny tenar
7050 utanfor prosjektet og installerte Skulelinux på den. Etter litt
7051 justering av konfigurasjonen med god hjelp av #skolelinux på IRC, var
7052 den nye tenaren oppe og gjekk med både tynne og halv-tjukke klientar.
7053 Autentisering gjekk mot det nye systemet, slik at elevar og lærarar
7054 framleis har same brukarnamn og passord over alt. Dette berre
7055 fungerte, og vi bestemte oss for å erstatte delar av løysinga vi
7056 skulle få levert med Skulelinux.
</p
>
7058 <p
>Det høyrer med til historia at det nye systemet eg skulle drive frå
7059 januar
2008 endå ikkje er ferdig levert. Dei jobbar med saka, seier
7060 dei, og har von om å fullføre leveransen i løpet av
2011.
</p
>
7062 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7064 <p
>Det er veldig mange. Eg skal ta nokre få.
</p
>
7066 <p
>Den viktigaste fordelen er at det igrunn berre er ei maskin å passe
7067 på, og det er tenaren. Med andre løysingar har ein gjerne programvare
7068 og anna som skal vedlikehaldast på kvar enkelt maskin. Med Skulelinux
7069 kan alle feil rettast og alle program oppgraderast på alle maskiner
7070 samstundes ved å gjere endringa som må til på tenaren. Eg kan sitje
7071 på kontoret og passe på alle tenarane i kommunen derifrå.
</p
>
7075 <li
>Tynne klientar gjer det mogleg å bruke eldre utstyr lenge, so lenge
7076 tenaren er sterk nok. Ein liten tenar med eit par halv-moderne CPUar
7077 og
2 GiB RAM held lenge for eit typisk klasserom med
30 tynnklientar,
7078 og det er lett å utvide med fleire.
7080 <li
>Halvtjukke klientar gjer det mogleg å utnytte kapasiteten i litt
7081 nyare maskiner betre, og avlaste tenaren. Ingenting vert installert
7082 lokalt på desse heller, og harddisken kan gjerne koblast frå. Gode
7083 halvtjukke klientar kan kjøpast brukt for under
1000-lappen, og det er
7084 heile kostnaden. Ingen lisensar eller anna på toppen, og det er ikkje
7085 krav til kraftigare tenar heller.
7087 <li
>Det er Linux. Vi har ikkje noko kluss med drivarar, dei berre er
7088 der. Heller ikkje med virus, dei finst i realiteten ikkje. Eller med
7089 elevar som klussar med installert programvare, for dei klarar ikkje å
7090 øydeleggje for nokon andre enn seg sjølve.
7094 <p
>Skulelinux er lagt opp til å vere veldig lett å installere rett ut
7095 av boksen på ein heil skule av ein interessert lærar. Det er ofte ei
7096 god løysing for skulen. Å ha nokon til stades som kjenner systemet og
7097 kan forklare enkle ting eller løyse problem der og då, er uvurderleg
7098 viktig for ein stressa lærar fem minutt før det ringer inn.

7102 <p
>All den ferdige konfigurasjonen gjer det tungvint å tilpasse
7103 Skulelinux til eit system som skal fungere saman med mange andre
7104 installasjonar i eit felles datanett for skulane i ein kommune. Det
7105 heile er prekonfigurert for ein skule, og utviding til mange skular
7106 med eigne tenarar er ikkje berre enkelt.

7110 <p
>Eg brukar mest alle små hjelpeprogram som føl med operativsystemet,
7111 samt scriptspråket perl. Elles er Firefox/Iceweasel, Gnome-terminal
7112 og ssh i kontinuerleg bruk. Av Linux-distribusjonar brukar eg både
7113 Debian, Ubuntu, SuSE og RedHat dagleg. Eg prøvar å finne det verktyet
7114 som passar best til kvar del av jobben.

7119 <p
>Det er to målgrupper ein må sikte mot. Det eine er alle skulane som
7120 manglar eller har eit lite tilfredsstillande opplegg i dag, og ikkje
7121 har råd til å kjøpe noko nytt og blankpussa opplegg. Der er det om å
7122 gjere å gjere det enkelt for skulane å finne Skulelinux, og gjere det
7123 enkelt for dei å få hjelp til installasjon på skulen. Gjerne med
7124 lokale kontaktpersonar. Her er det dugnadsinnsats som må til, for
7125 desse skulane har ikkje råd til å betale for dette.
</p
>
7127 <p
>Den andre og kanskje viktigare målgruppa er dei meir eller mindre
7128 profesjonelle kundane. Alle store offentlege innkjøp, inkludert
7129 innkjøp av nytt datasystem for skular, må ut på offentleg anbod.
7130 Offentlege anbod er mykje meir lukka enn dei gjev inntrykk av, og både
7131 regelboka og boka med triks for å sminke tilbodet er tjukk. Det er
7132 vanskeleg å komme inn utan eit solid salsapparat i ryggen. Kanskje
7133 Skulelinux skulle prøve aktivt å få seg eit partnarskap med eit av dei
7134 store som gjerne vil sterkare inn på den offentlege IT-marknaden?
7135 Nokon som kjenner triksa og har krefter til å ta opp kampen mot både
7136 dårlege anbod og Rudolf Blostrupmoen IT AS. Leveranse til skulane i
7137 ein kommune er ein god måte å få ein fot inn døra som leverandør til
7138 ein lukrativ kommunemarknad som kjøper alle tenester. Ta kontakt med
7139 nokon som er passeleg store og ikkje er Microsoft-partnar, og fortell:
7140 «Vi har eit ferdig produkt som du kan selje. Nei vi skal ikkje ha for
7141 det. Du kan gjerne gjere kva du vil med det, berre vi får lov til å
7142 hjelpe deg. Målgruppa er alle kommunar, og det er noko dei vil ha.
7143 Det er eit godt produkt, brukt av mange og godt likt.»

7169 <p
>Jeg leste en artikkel om en dugnadsinstallasjon av Skolelinux på en
7170 skole på Jæren et sted. Tanken om dugnad og frihet appellerte til
7171 meg. Da vi skulle bygge ny skole var det en del vi måtte spare på,
7172 fordi vi beveget oss mot en kostnadssprekk. Kabling og investering i
7173 PC-er var en av tingene vi sparte på. Derfor kjøpe vi
72 pc-er for
390
7174 pr stk. En filtjener og en applikasjonsserver.

7178 <p
>Fordelen er at så mye er satt opp fra starten. I tillegg er det
7179 tydelig at pakka er laga for skoleverket. Brukerne har egne
7180 skrivebord, tilgang på mange gode verktøyprogrammer. Vi slipper å
7181 tenke på virus. Brukerne har ikke mulighet til å ødelegge
7182 klientoppsett, men har gode muligheter til å endre eget oppsett. Dette
7183 tror jeg er inspirerende og kjekt for mange brukere. Mappestrukturen
7184 er ferdig og det er
"enkelt
" å designe lokale mappestrukturer via
7185 skeleton. Noen av oss i skoleverket mener skolen skal være en
7186 "mot-kultur
". Da er Skolelinux et av valgene man kan ta. Et annet er å
7187 spise på indisk restaurant i stedet for Mc Donald
's når vi er på bytur
7188 osv.. Ordene deling, frihet, dugnad osv er positive ord i
7189 skoleverket. Det er viktig at elevene blir bevisst dette.

</strong
></p

7193 <p
>Kompabiliteten er selvsagt et problem, selv om det er mindre nå enn
7194 før. For IKT-personer på skolene som skal drifte dette er det
7195 problematisk med kommandoer i terminalen. I tillegg er det alt for
7196 mange programmer i Skolelinux som ikke blir brukt. Jeg tror
7197 Skolelinux er tjent med å tone ned begrepet pedagogisk programvare.
7198 Slik jeg ser det finnes ikke denne kategorien programmer lengre slik
7199 de gjorde før, som frittsående programmer som installeres på en
7200 datamaskin eller på serveren. Det finnes en del spesialpedagogiske
7201 programmer, som Textpilot, LingDys, LingRight, AskiRaski, Ny i Norge
7202 osv. Men dette er programmer for enkelt-elever eller små grupper av
7203 elever. Det som bør være fokus er at alle undervisningsressurser som
7204 lages for nettet skal være nettleseruavhengig.

7208 <p
>OpenOffice bruker jeg til vanlig kontorarbeide. VLC bruker jeg som
7209 videoavspiller og av og til streaming av film. Gimp bruker jeg i
7210 undervisningen til bildemanipulering. Firefox og Chrome er mine
7211 favoritt-nettlesere. Firefox har lenge vært førstevalget mitt, nå
7212 bruker jeg mest Chrome. Opplever den som raskere og smidigere enn
7213 Firefox. Ubuntu bruker jeg som dualboot på jobb-maskinen min i
7214 tillegg til at alle PCer hjemme har en eller annen Ubuntu-distribusjon
7215 installert. Jeg bruker Clonezilla på Ubuntu
10.04 til kloning av
7216 datamaskiner på jobb. Det er selvsagt en haug andre frie programmer
7217 jeg bruker men jeg bruker dem ikke daglig. Jeg kan ramse opp:
7218 recordmydesktop, cinelerra, acidrip, soundjuicer, audacity, NX
7219 (no-machine), Kino, Rythmbox...

7221 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
7222 skoler til å ta i bruk fri programvare?
</strong
></p
>
7224 <p
>Jeg tror oppsøkende virksomhet er den rette strategien.
7225 Ressurspersoner gjør avtaler med rådmenn, skolesjefer, rektorer. Det
7226 er slik konkurrentene gjør det. Fokuset i slike samtaler bør være
7227 kost-nytte. Dersom personer med økonomisk ansvar ser at de kan få
7228 like godt tilbud til mindre utgifter, tror jeg det er mulighet til å
7229 få innpass. Dersom de også kan få konkrete tilbud på drift i slike
7230 samtaler, vil de kanskje bli litt mer interesserte i hvor mye penger
7231 som faktisk går til IKT i skolene. Det er også viktig at vi ikke
7232 firer for mye på krav til datamaskiner. Det er flott at Skolelinux
7233 går på
"utrangert
" utstyr, men dette bør bare presenteres som et
7234 alternativ. Skolelinux-installasjoner med utrangert utstyr er ikke å
7235 foretrekke dersom man kan unngå det. Det skaper ikke entusiasme hos
7236 brukerne (elever og lærere) når de bruker gamle datamaskiner som går
7237 tregt. Det er kjempefint med skoler som har kommet seg frem til
7238 Skolelinux og fri programvare av seg selv, men de lever på nåde.
7239 Slike valg må fundamenteres hos skoleeier.

17
7263 servere basert på Skolelinux og Debian. Jeg holder i tillegg noen kurs

>Gjennom en eller annen nettavis i
2001 der var det skrevet om
7271 Skolelinux. Artikkelen ga meg lyst til å prøve ut systemet.
</p

7273 <p
>Det startet i
2002 ved at jeg installerte en av de første utgavene
7274 av Skolelinux på en standard pc på Solneset skole i Tromsø. Denne var
7275 oppe fram til desember
2003 da jeg sluttet på den skolen og begynte i
7276 ny jobb i Narvik kommune.

7278 <p
> I Narvik kommune var det i
2004 kun
2 servere på da totalt
15
7279 skoler. Disse var Windows NT baserte. På disse to skolene var det lite
7280 med maskiner. Jobben med å få Narvik Kommune opp på akseptabelt nivå
7281 virket å være formidabel. Men med hjelp av gode kollegaer og leder
7282 skrev jeg en IKT plan for Narvik kommune som ble vedtatt av politikere
7283 i august
2004. I denne planen ble det bestemt at Narvik kommune skulle
7284 bruke Skolelinux. Her ble det også satt av midler til kabling av god
7285 infrastruktur på alle skoler samt innkjøp av nye datamaskiner. Så i
7286 dag har vi
17 servere hvorav
13 er på Skolelinux, med ca
1500 klienter
7287 basert på tynne,
"halvtykke
" og et stort antall bærbare pcer basert på

7368 bidra til at Trondheim kommune satte igang Selsbakk ungdomskole som et
7369 pilotprosjekt med Skolelinux, som egentlig var og er en stor suksess,
7370 men det virker ut som det ikke skjer noe mer på. I tillegg var vi med

7377 nytteverdien. Dette fordi det har forholdsvis lav inngangsum og bruker
7378 en arkitektur med sentral-drift som gir mange driftfordeler. I
7379 tillegg vil det kunne frigjøre kostnader for skolene slik at de kan
7380 bruke dem til å ansette f,eks flere lærere om det er ønskelig.

7422 <p
>Kommunen min har to omtrent jevnstore tettsteder, og en
7423 ungdomsskole i hvert av tettstedene. Den minste av disse har ca
300
7424 elever og til denne sogner det
3 barneskoler. Den største har ca
350
7425 elever og til denne sogner det
4 barneskoler.
</p
>
7429 <li
>Kommunen har i veldig lang tid forsømt IKT i skolen, og det har
7430 bare blitt gitt smuler i ny og ne. Det er kun den største av
7431 ungdomsskolene som har hatt en skikkelig datapark, og dette takket
7432 være en naturfaglærer som ble lei av å vente på kommunen. Det gjorde
7433 at vi bestemte oss for å ta ting i egne hender, og da vha
7434 skolelinux. En testinstallasjon med
10 gamle PCer ble gjort, og vi så
7435 raskt at dette var veldig lovende. Neste etappe var å gi alle lærere
7436 egen PC på arbeidsplassene sine (
2004), og så sette opp
16 PCer på to
7437 datarom. Vi har kun basert oss på å kjøpe inn brukte maskiner, og
7438 aldri dyrere enn
1000 kr pr klient. For to år siden så hadde vi
7439 klienter i alle klasserom, og totalt hadde vi da rundt
250 stk. Rundt
7440 40 klienter brukes av lærerne og kjører på en egen server. Elvene har
7441 resten, og kjører også en egen server. Servere har vi også kjøpt
7442 brukt,
2 år gamle servere koster
6-
7000 kroner.
</li
>
7444 <li
>Skolen vår er et relativt gammelt bygg, men en meget dyktig
7445 vaktmester har sammen med IKT-ansvarlig/Naturfaglærer lagt kabler til alle
7446 rom. Gradvis har vi byttet ut billige svitsjer med mer solide saker
7447 som er mulig å fjernstyre.
</li
>
7449 <li
>Vi har i all hovedsak greid å få dette til over eget budsjett, men
7450 vi har også passet på å få penger når de andre skolene har fått
7451 bærbare PCer til lærere osv.
</li
>
7453 <li
>Vår IKT-ansvarlig har gjort (og gjør) en fenomenal jobb, og vi har
7454 en maskinpark som de andre av kommunens skoler bare kan drømme
7459 <p
>Så skjer det som ofte skjer. Det kommer en eller annen
7460 selger/blåruss og skal fikse ALT. I vårt tilfelle betyr dette også
7461 sentralisering av drift. Den ny-ansatte på kommunens IT-avdelingen
7462 skal også ha jobb, og ser for seg å ta over skoledriften. Kommunen
7463 kjøper inn eksterne driftstjenester, og nekter i samme slengen å ta
7464 hensyn til skolen vår. Dette til tross for at vi alene har like mange
7465 datamaskiner som de andre til sammen.
</p
>
7469 <li
>Det blir krevd at vi skal innlemmes i de kommunale systemet, og
7470 det er VI som får ansvar for at dette kommer på plass. Og det er her
7471 de horrible tingene begynner å skje.
</li
>
7473 <li
>Det settes opp en lukket Exchange server som gjør av vi ikke kan
7474 hente epost for våre ansatte. Og det kreves at vi finner løsning på
7477 <li
>Det velges sak arkivsystem som vi pålegges å bruke, noe som gjør
7478 at vi må bruke en terminalløsning mot kommunal server. Ikke i seg selv
7479 et problem i følge IKT-ansvarlig hos oss. Men kommunens IT-avd nektet
7480 faktisk å åpne de porter OSV som vi måtte bruke.
</li
>
7482 <li
>Vi blir pålagt å flytte på innsiden av det kommunale
7483 nettverket. Dette gjorde at vi mistet hjemmekontor for lærere og
7484 elever. Å få åpnet porter i kommunal brannmur var ikke
7485 aktuelt. Mulighet for fjerndrift ble også vekk i samme slengen.
</li
>
7487 <li
>Vår LMS Moodle er ikke mulig å nå for elevene og lærerne.
7491 <p
>Den andre ungdomsskolen i kommunen begynner så å kreve at de skal
7492 få bedre datatetthet, og komme opp på et nivå som ligner det vi
7493 har. De ser at vi kan avholde eksamen hvor alle
10. klassingene får
7494 sitte ved hver sin PC. Og de har fått tilbakemelding (klager) fra VGS
7495 om manglende datakompetanse på elevene som kommer fra dem. Dette fører
7496 videre til at kommunen endelig innser at de må ta grep.
</p
>
7498 <p
>Grepet betyr sentralisering, og farvel til vår plattform får vi
7499 høre. Det blir gjort en rekke bestemmelser og vedtak som vi ikke får
7500 være en del av. Det blir helt klart at vi må redusere antall maskiner,
7501 og det skal satses på bærbare maskiner. Siden vi ikke har fått tatt
7502 del i prosessene som angår oss, så bruker vi fagforening. Vi har ikke
7503 blitt hørt i forbindelse med endringer som er betydelig for vår
7504 hverdag, og greier å stoppe omlegging. I tillegg så har vi et politisk
7505 vedtak i kommunen på at vi skal kjøre Linux på elevnett, og dette
7506 vedtaket kan ikke administrasjonen i kommunene helt uten videre
7507 tilsidesette.
</p
>
7509 <p
>I sum har dette gjort at vi har fått jobbe videre i fred. Og en del
7510 runder i kommunens kontrollutvalg har gjort det tydelig at vi har blitt
7511 systematisk motarbeidet.

7513 <p

7514 lærere, men etter
2 år med innkjøring er det fremdeles problemer

7535 men med omgivelsene rundt som vil oss til livs. Men det har vært verdt

7582 har også truet med å si opp jobben sin hvis det ikke ble tatt hensyn i
7583 større grad enn hva som har vært tilfelle. VI kan også dokumentere
7584 flere brudd på anbudsregler, og vi kjenner til at relativt store
7585 IT-leverandører som ikke har fått tatt del i disse anbudene, rett og
7586 slett ikke tør melde fra av redsel for å få et dårlig rykte.

7592 <p
>Jeg glemte å nevne at vi nå nesten ikke bruker tid på å drifte
7593 systemet vårt, noe som gjør at det aller meste av tid blir brukt til å
7594 støtte lærerne og elevene. F.eks så bruker vår IKT-ansvarlig den
7595 første timen på jobb,
0730-
0830 kun til å gå ute på arbeidsplassene
7596 til læreren. Dette for å kunne svare på små og store problem, gi tips
7597 og råd, eller bare for å plukke opp hva som er behovet ute i
7598 undervisningsarealene. Det er dessverre ikke slik at alle lærerne har
7599 nok digital kompetanse til å kunne formulere alle spørsmålene de har,
7600 men ved å kunne få vise eller lufte tanker med IKT-ansvarlig så er det
7601 utrolig hva som kommer fram.
</p
>
7605 <li
>Jeg ser at mange bruker økonomi som argument i forhold til å bruke
7606 SkoleLinux, og jeg skal ikke legge skjul på at det var dette som i
7607 utgangspunktet var årsaken til vårt valg. Men diskusjonene og kampen
7608 med kommunens IT-avdeling har gjort at vi har fått et noe annet
7609 fokus. Fordelene med drift og stabilitet, gjør at vi ville ha valgt
7610 samme løsning selv om den var dyrere. At vi slipper langt billigere
7611 unna, som følge av
0,- lisenskostnader og lave maskinvarekostnader, er
7612 bare en bonus.
</li
>
7614 <li
>Etter å ha kranglet oss til å få skikkelig oversikt over hva de
7615 andre skolene i kommunen bruker på IT, så har vi fått gehør for å få
7616 samme midler til innkjøp. Dette har gjort at vi nå kan kjøpe inn
7617 utstyr som de andre skolene bare kan se langt etter. Vi har nettopp
7618 kjøpt inn
3 videokamera i semiproff-klassen for å kunne lage film,
7619 samt sende live fra skoleteater/konserter. Vi har kjøpt inn digitale
7620 kompaktkamera til alle klassene. Vi har et team av lærere som skal i
7621 gang med å teste ut tablets på svake elever. Håpet et at teknologien
7622 kan være med på å gi noen av elevene litt mer motivasjon. Vi har kjøpt
7623 inn et halvt klassesett med pulsklokker, noe som har vist seg å være
7624 overraskende inspirerende for en del av elevene. Vi har også oss på
7625 fag på en høyskole litt lengre sør for oss, slik at
3 av oss nå skal
7626 ta faget
"Linux tjenestedrift
". Som inspektør og en del av skolens
7627 administrasjon er det veldig praktisk å kunne trå til hvis det

7633 problem. Det å få fingrene på problem og utfordringer er den aller

7671 years the university have organised shared bid of a few thousand
7672 computers, and this year HP won the bid. Two different desktops and
7673 five different laptops are on the list this year. We in the UNIX

7679 perhaps inspire others to test hardware as well. To test, I PXE
7680 install the OS version of choice, and log in as my normal user and run
7681 a few applications and plug in selected pieces of hardware. When
7682 something fail, I make a note about this in the test matrix and move
7683 on. If I have some spare time I try to report the bug to the OS
7684 vendor, but as I only have the machines for a short time, I rarely
7685 have the time to do this for all the problems I find.

7780 <title>Why isn

7784 <description><p
>In the latest issue of Linux Journal, the readers choices were
7785 presented, and the winner among the multimedia player were VLC.
7786 Personally, I like VLC, and it is my player of choice when I first try
7787 to play a video file or stream. Only if VLC fail will I drag out
7788 gmplayer to see if it can do better. The reason is mostly the failure
7789 model and trust. When VLC fail, it normally pop up a error message
7790 reporting the problem. When mplayer fail, it normally segfault or
7791 just hangs. The latter failure mode drain my trust in the program.
<p
>
7793 <p
>But even if VLC is my player of choice, we have choosen to use
7794 mplayer in
<a href=
"http://www.skolelinux.org/
">Debian
7795 Edu/Skolelinux
</a
>. The reason is simple. We need a good browser
7796 plugin to play web videos seamlessly, and the VLC browser plugin is
7797 not very good. For example, it lack in-line control buttons, so there
7798 is no way for the user to pause the video. Also, when I
7799 <a href=
"http://wiki.debian.org/DebianEdu/BrowserMultimedia
">last
7800 tested the browser plugins
</a
> available in Debian, the VLC plugin
7801 failed on several video pages where mplayer based plugins worked. If
7802 the browser plugin for VLC was as good as the gecko-mediaplayer
7803 package (which uses mplayer), we would switch.
</P
>
7805 <p
>While VLC is a good player, its user interface is slightly
7806 annoying. The most annoying feature is its inconsistent use of
7807 keyboard shortcuts. When the player is in full screen mode, its
7808 shortcuts are different from when it is playing the video in a window.
7809 For example, space only work as pause when in full screen mode. I
7810 wish it had consisten shortcuts and that space also would work when in
7811 window mode. Another nice shortcut in gmplayer is [enter] to restart
7812 the current video. It is very nice when playing short videos from the
7813 web and want to restart it when new people arrive to have a look at
7814 what is going on.

8582 architecture in Debian as a file server in NUUG to get access to the
5
8583 TB zfs volume we currently use to store DV video. Because of this, I
8584 finally got around to do a test installation of Debian/Squeeze with
8585 kfreebsd. Installation went fairly smooth, thought I noticed some
8586 visual glitches in the cdebconf dialogs (black cursor left on the
8587 screen at random locations). Have not gotten very far with the
8588 testing. Noticed cfdisk did not work, but fdisk did so it was not a
8589 fatal problem. Have to spend some more time on it to see if it is
8590 useful as a file server for NUUG. Will try to find time to set up a
8591 gnash buildbot slave on the Debian Edu/Skolelinux this weekend.

>Prioritising packages for the Debian Edu /
8601 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
> DVD, which is
8602 supposed provide a school with all the services and user applications
8603 needed on the pupils computer network has always been hard. Even
8604 schools without Internet connections should be able to get Debian Edu
8605 working using this DVD.
</p
>
8607 <p
>The job became a lot harder when apt and aptitude started
8608 installing recommended packages by default. We want the same set of
8609 packages to be installed when using the DVD and the netinst CD, and
8610 that means all recommended packages need to be on the DVD. I created
8611 a patch for debian-cd in
<a href=
"http://bugs.debian.org/
601203">BTS
8612 report #
601203</a
> to do this, and since this change was applied to
8613 the Debian Edu DVD build, we have been seriously short on space.
</p
>
8615 <p
>A few days ago we decided to drop blender, wxmaxima and kicad from
8616 the default installation to save space on the DVD, believing that
8617 those needing these applications are few and can get them from the
8618 Debian archive.
</p
>
8620 <p
>Yesterday, I had a look what source packages to see which packages
8621 were using most space. A few large packages are well know;
8622 openoffice.org, openclipart and fluid-soundfont. But I also
8623 discovered that lilypond used
106 MiB and fglrx-driver used
53 MiB.
8624 The lilypond package is pulled in as a dependency for rosegarden, and
8625 when looking a bit closer I discovered that
99 MiB of the
106 MiB were
8626 the documentation package, which is recommended by the binary package.
8627 I decided to drop this documentation package from our DVD, as most of
8628 our users will use the GUI front-ends and do not need the lilypond
8629 documentation. Similarly, I dropped the non-free fglrx-driver package
8630 which might be installed by d-i when its hardware is detected, as the
8631 free X driver should work.
</p
>
8633 <p
>With this change, we finally got space for the LXDE and Gnome
8634 desktop packages as well as the language specific packages making the
8635 DVD more useful again.

8646 <p
>My
<a href=
"http://pledgebank.com/gnash-avm2
">gnash pledge
</a
> to
8647 raise money for the project is going well. The lower limit of
10
8648 signers was reached in
24 hours, and so far
13 people have signed it.
8649 More signers and more funding is most welcome, and I am really curious
8650 how far we can get before the time limit of December
24 is reached.
8653 <p
>On the #gnash IRC channel on irc.freenode.net, I was just tipped
8654 about what appear to be a great code coverage tool capable of
8655 generating code coverage stats without any changes to the source code.
8657 <a href=
"http://simonkagstrom.github.com/kcov/index.html
">kcov
</a
>,
8658 and can be used using
<tt
>kcov
&lt;directory
&gt;
&lt;binary
&gt;
</tt
>.
8659 It is missing in Debian, but the git source built just fine in Squeeze
8660 after I installed libelf-dev, libdwarf-dev, pkg-config and
8661 libglib2.0-dev. Failed to build in Lenny, but suspect that is
8662 solvable. I hope kcov make it into Debian soon.
</p
>
8664 <p
>Finally found time to wrap up the release notes for
<a

">a

8667 alpha test release of the Squeeze based Debian Edu /
8668 <a href=

">Skolelinux
</a
>
8669 release. Give it a try if you need a complete linux solution for your
8670 school, including central infrastructure server, workstations, thin
8671 client servers and diskless workstations. A nice touch added
8672 yesterday is RDP support on the thin client servers, for windows
8673 clients to get a Linux desktop on request.

8684 second most popular used package that is missing in Debian. The sixth
8685 most popular is flashplayer-mozilla. This is a clear indication that

8694 schools experienced with
<a href=

8700 <p
>I once saw a funny and sad comment in a web forum, where Linux was
8701 said to be the retarded cousin that did not really understand
8702 everything you told him but could work fairly well. This was a
8703 comment regarding the problems Linux have with proprietary formats and
8704 non-standard web pages, and is sad because it exposes a fairly common
8705 understanding of whose fault it is if web pages that only work in for
8706 example Internet Explorer
6 fail to work on Firefox, and funny because
8707 it explain very well how annoying it is for users when Linux
8708 distributions do not work with the documents they receive or the web
8709 pages they want to visit.

8712 and Debian Edu to have a well working Flash implementation in the

8715 to include the latest version of Gnash that will make this happen, as
8716 the new release
0.8.8 was published a few weeks ago and is resting in

8718 The Gnash maintainers have asked for a freeze exception, but the
8719 release team have not had time to reply to it yet. I hope they agree
8720 with me that Flash is important for the Debian desktop users, and thus
8721 accept the new package into Squeeze.

8895 <description><p
>As reported earlier, the last few days I have looked at how Debian
8896 Edu clients are configured, and tried to get rid of all hardcoded
8897 configuration settings on the clients. I believe the work to be
8898 mostly done, and the clients seem to work just fine with dynamically
8899 generated configuration.
</p
>
8901 <p
>What is the point, you might ask? The point is to allow a Debian
8902 Edu desktop to integrate into an existing network infrastructure
8903 without any manual configuration.
</p
>
8905 <p
>This is what happens when installing a Debian Edu client here at
8906 the University of Oslo using PXE. With the PXE installation, I am
8907 asked for language (Norwegian Bokmål), locality (Norway) and keyboard
8908 layout (no-latin1), Debian Edu profile (Roaming Workstation), if I
8909 accept to reformat the hard drive (yes), if I want to submit info to
8910 popcon.debian.org (no) and root password (secret). After answering
8911 these questions, the installer goes ahead and does its thing, and
8912 after around
50 minutes it is done. I press enter to finish the
8913 installation, and the machine reboots into KDE. When the machine is
8914 ready and kdm asks for login information, I enter my university
8915 username and password, am told by kdm that a local home directory has
8916 been created and that I must log in again, and finally log in with the
8917 same username and password to the KDE
4.4 desktop. At no point during
8918 this process did it ask for university specific settings, and all the
8919 required configuration was dynamically detected using information
8920 fetched via DHCP and DNS. The roaming workstation is now ready for
8923 <p
>How was this done, you might wonder? First of all, here is the
8924 list of things that need to be configured on the client to get it
8925 working properly out of the box:
</p
>
8928 <li
>IP address/netmask and DNS server.
</li
>
8929 <li
>Web proxy URL.
</li
>
8930 <li
>LDAP server for NSS directory information (user, group, etc).
</li
>
8931 <li
>Kerberos server for PAM password checking.
</li
>
8932 <li
>SMB mount point to access the network home directory. (*)
</li
>
8933 <li
>Central syslog server to send syslog messages to. (*)
</li
>
8934 <li
>Sitesummary collector URL to submit info to central server. (*)
</li
>
8937 <p
>(Hm, did I forget anything? Let me knew if I did.)
</p
>
8939 <p
>The points marked (*) are not required to be able to use the
8940 machine, but needed to provide central storage and allowing system
8941 administrators to track their machines. Since yesterday, everything
8942 but the sitesummary collector URL is dynamically discovered at boot
8943 and installation time in the svn version of Debian Edu.
</p
>
8945 <p
>The IP and DNS setup is fetched during boot using DHCP as usual.
8946 When a DHCP update arrives, the proxy setup is updated by looking for
8947 http://wpat/wpad.dat and using the content of this WPAD file to
8948 configure the http and ftp proxy in /etc/environment and
8949 /etc/apt/apt.conf. I decided to update the proxy setup using a DHCP
8950 hook to ensure that the client stops using the Debian Edu proxy when
8951 it is moved outside the Debian Edu network, and instead uses any local
8952 proxy present on the new network when it moves around.
</p
>
8954 <p
>The DNS names of the LDAP, Kerberos and syslog server and related
8955 configuration are generated using DNS information at boot. First the
8956 installer looks for a host named ldap in the current DNS domain. If
8957 not found, it looks for _ldap._tcp SRV records in DNS instead. If an
8958 LDAP server is found, its root DSE entry is requested and the
8959 attributes namingContexts and defaultNamingContext are used to
8960 determine which LDAP base to use for NSS. If there are several
8961 namingContexts attibutes and the defaultNamingContext is present, that
8962 LDAP subtree is used as the base. If defaultNamingContext is missing,
8963 the subtrees listed as namingContexts are searched in sequence for any
8964 object with class posixAccount or posixGroup, and the first one with
8965 such an object is used as the LDAP base. For Kerberos, a similar
8966 search is done by first looking for a host named kerberos, and then
8967 for the _kerberos._tcp SRV record. I
've been unable to find a way to
8968 look up the Kerberos realm, so for this the upper case string of the
8969 current DNS domain is used.
</p
>
8971 <p
>For the syslog server, the hosts syslog and loghost are searched
8972 for, and the _syslog._udp SRV record is consulted if no such host is
8973 found. This algorithm works for both Debian Edu and the University of
8974 Oslo. A similar strategy would work for locating the sitesummary
8975 server, but have not been implemented yet. I decided to fetch and
8976 save these settings during installation, to make sure moving to a
8977 different network does not change the set of users being allowed to
8978 log in nor the passwords required to log in. Usernames and passwords
8979 will be cached by sssd when the user logs in on the Debian Edu
8980 network, and will not change as the laptop move around. For a
8981 non-roaming machine, there is no caching, but given that it is
8982 supposed to stay in place it should not matter much. Perhaps we
8983 should switch those to use sssd too?
</p
>
8985 <p
>The user
's SMB mount point for the network home directory is
8986 located when the user logs in for the first time. The LDAP server is
8987 consulted to look for the user
's LDAP object and the sambaHomePath
8988 attribute is used if found. If it isn
't found, the home directory
8989 path fetched from NSS is used instead. Assuming the path is of the
8990 form /site/server/directory/username, the second part is looked up in
8991 DNS and used to generate a SMB URL of the form
8992 smb://server.domain/username. This algorithm works for both Debian
8993 edu and the University of Oslo. Perhaps there are better attributes
8994 to use or a better algorithm that works for more sites, but this will
8995 do for now. :)
</p
>
8997 <p
>This work should make it easier to integrate the Debian Edu clients
8998 into any LDAP/Kerberos infrastructure, and make the current setup even
8999 more flexible than before. I suspect it will also work for thin
9000 client servers, allowing one to easily set up LTSP and hook it into a
9001 existing network infrastructure, but I have not had time to test this
9004 <p
>If you want to help out with implementing these things for Debian
9005 Edu, please contact us on debian-edu@lists.debian.org.
</p
>
9007 <p
>Update
2010-
08-
09: Simon Farnsworth gave me a heads-up on how to
9008 detect Kerberos realm from DNS, by looking for _kerberos TXT entries
9009 before falling back to the upper case DNS domain name. Will have to
9010 implement it for Debian Edu. :)

9019 <description><p
>A few years ago, I was involved in a project planning to use
9020 Windows file servers as home directory servers for Debian
9021 Edu/Skolelinux machines. This was thought to be no problem, as the
9022 access would be through the SMB network file system protocol, and we
9023 knew other sites used SMB with unix and samba as the file server to
9024 mount home directories without any problems. But, after months of
9025 struggling, we had to conclude that our goal was impossible.
</p
>
9027 <p
>The reason is simply that while SMB can be used for home
9028 directories when the file server is Samba running on Unix, this only
9029 work because of Samba have some extensions and the fact that the
9030 underlying file system is a unix file system. When using a Windows
9031 file server, the underlying file system do not have POSIX semantics,
9032 and several programs will fail if the users home directory where they
9033 want to store their configuration lack POSIX semantics.
</p
>
9035 <p
>As part of this work, I wrote a small C program I want to share
9036 with you all, to replicate a few of the problematic applications (like
9037 OpenOffice.org and GCompris) and see if the file system was working as
9038 it should. If you find yourself in spooky file system land, it might

>A few days ago, I
9251 <a href=
"http://people.skolelinux.org/pere/blog/Debian_Edu_roaming_workstation___at_the_university_of_Oslo.html
">tried
9252 to install
</a
> a Roaming workation profile from Debian Edu/Squeeze
9253 while on the university network here at the University of Oslo, and
9254 noticed how much had to change to get it operational using the
9255 university infrastructure. It was fairly easy, but it occured to me
9256 that Debian Edu would improve a lot if I could get the client to
9257 connect without any changes at all, and thus let the client configure
9258 itself during installation and first boot to use the infrastructure
9259 around it. Now I am a huge step further along that road.
</p
>
9261 <p
>With our current squeeze-test packages, I can select the roaming
9262 workstation profile and get a working laptop connecting to the
9263 university LDAP server for user and group and our active directory
9264 servers for Kerberos authentication. All this without any
9265 configuration at all during installation. My users home directory got
9266 a bookmark in the KDE menu to mount it via SMB, with the correct URL.
9267 In short, openldap and sssd is correctly configured. In addition to
9268 this, the client look for http://wpad/wpad.dat to configure a web
9269 proxy, and when it fail to find it no proxy settings are stored in
9270 /etc/environment and /etc/apt/apt.conf. Iceweasel and KDE is
9271 configured to look for the same wpad configuration and also do not use
9272 a proxy when at the university network. If the machine is moved to a
9273 network with such wpad setup, it would automatically use it when DHCP
9274 gave it a IP address.
</p
>
9276 <p
>The LDAP server is located using DNS, by first looking for the DNS
9277 entry ldap.$domain. If this do not exist, it look for the
9278 _ldap._tcp.$domain SRV records and use the first one as the LDAP
9279 server. Next, it connects to the LDAP server and search all
9280 namingContexts entries for posixAccount or posixGroup objects, and
9281 pick the first one as the LDAP base. For Kerberos, a similar
9282 algorithm is used to locate the LDAP server, and the realm is the
9283 uppercase version of $domain.
</p
>
9285 <p
>So, what is not working, you might ask. SMB mounting my home
9286 directory do not work. No idea why, but suspected the incorrect
9287 Kerberos settings in /etc/krb5.conf and /etc/samba/smb.conf might be
9288 the cause. These are not properly configured during installation, and
9289 had to be hand-edited to get the correct Kerberos realm and server,
9290 but SMB mounting still do not work. :(
</p
>
9292 <p
>With this automatic configuration in place, I expect a Debian Edu
9293 roaming profile installation would be able to automatically detect and
9294 connect to any site using LDAP and Kerberos for NSS directory and PAM
9295 authentication. It should also work out of the box in a Active
9296 Directory environment providing posixAccount and posixGroup objects
9297 with UID and GID values.

>The new roaming workstation profile in Debian Edu/Squeeze is fairly
9310 similar to the laptop setup am I working on using Ubuntu for the
9311 University of Oslo, and just for the heck of it, I tested today how
9312 hard it would be to integrate that profile into the university
9313 infrastructure. In this case, it is the university LDAP server,
9314 Active Directory Kerberos server and SMB mounting from the Netapp file
9317 <p
>I was pleasantly surprised that the only three files needed to be
9318 changed (/etc/sssd/sssd.conf, /etc/ldap.conf and
9319 /etc/mklocaluser.d/
20-debian-edu-config) and one file had to be added
9320 (/usr/share/perl5/Debian/Edu_Local.pm), to get the client working.
9321 Most of the changes were to get the client to use the university LDAP
9322 for NSS and Kerberos server for PAM, but one was to change a hard
9323 coded DNS domain name in the mklocaluser hook from .intern to
9326 <p
>This testing was so encouraging, that I went ahead and adjusted the
9327 Debian Edu scripts and setup in subversion to centralise the roaming
9328 workstation setup a bit more and avoid the hardcoded DNS domain name,
9329 so that when I test this tomorrow, I expect to get away with modifying
9330 only /etc/sssd/sssd.conf and /etc/ldap.conf to get it to use the
9331 university servers.
</p
>
9333 <p
>My goal is to get the clients to have no hardcoded settings and
9334 fetch all their initial setup during installation and first boot, to
9335 allow them to be inserted also into environments where the default
9336 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
9467 been working hard to get the Debian/Squeeze based version of Debian
9468 Edu/Skolelinux into shape. This future version will use Kerberos for
9469 authentication, and services are slowly migrated to single signon,
9470 getting rid of password questions one at the time.
</p
>
9472 <p
>It will also feature a roaming workstation profile with local home
9473 directory, for laptops that are only some times on the Skolelinux
9474 network, and for this profile a shortcut is created in Gnome and KDE
9475 to gain access to the users home directory on the file server. This
9476 shortcut uses SMB at the moment, and yesterday I had time to test if
9477 SMB mounting had started working in KDE after we added the cifs-utils
9478 package. I was pleasantly surprised how well it worked.
</p
>
9480 <p
>Thanks to the recent changes to our samba configuration to get it
9481 to use Kerberos for authentication, there were no question about user
9482 password when mounting the SMB volume. A simple click on the shortcut
9483 in the KDE menu, and a window with the home directory popped

9490 <p
>We had planned a alpha0 release of Debian Edu for today, but thanks
9491 to the autobuilder administrators for some architectures being slow to
9492 sign packages, we are still missing the fixed LTSP package we need for
9493 the release. It was uploaded three days ago with urgency=high, and if
9494 it had entered testing yesterday we would have been able to test it in
9495 time for a alpha0 release today. As the binaries for ia64 and powerpc
9496 still not uploaded to the Debian archive, we need to delay the alpha

9758 the DN pointed to by the dhcpServer entries. The latter should make

>For a while now, I have wanted to find a way to change the DNS and
9829 DHCP services in Debian Edu to use the same LDAP objects for a given
9830 computer, to avoid the possibility of having a inconsistent state for
9831 a computer in LDAP (as in DHCP but no DNS entry or the other way
9832 around) and make it easier to add computers to LDAP.

've looked at how powerdns and dhcpd is using LDAP, and using this
9835 information finally found a solution that seem to work.
</p

9837 <p
>The old setup required three LDAP objects for a given computer.
9838 One forward DNS entry, one reverse DNS entry and one DHCP entry. If
9839 we switch powerdns to use its strict LDAP method (ldap-method=strict
9840 in pdns-debian-edu.conf), the forward and reverse DNS entries are
9841 merged into one while making it impossible to transfer the reverse map
9842 to a slave DNS server.
</p
>
9844 <p
>If we also replace the object class used to get the DNS related
9845 attributes to one allowing these attributes to be combined with the
9846 dhcphost object class, we can merge the DNS and DHCP entries into one.
9847 I
've written such object class in the dnsdomainaux.schema file (need
9848 proper OIDs, but that is a minor issue), and tested the setup. It
9849 seem to work.
</p
>
9851 <p
>With this test setup in place, we can get away with one LDAP object
9852 for both DNS and DHCP, and even the LTSP configuration I suggested in
9853 an earlier email. The combined LDAP object will look something like

</p

9874 <p
>I am not yet sure if I can get the DHCP server to look for its
9875 dhcphost in a different location, to allow us to put the objects
9876 outside the
"DHCP Config

9877 that. If I can
't figure out a way to do that, we can still get rid of
9878 the hosts subtree and move all its content into the DHCP Config tree

10097 <description><p
>For a laptop, centralized user directories and password checking is
10098 a bit troubling. Laptops are typically used also when not connected
10099 to the network, and it is vital for a user to be able to log in or
10100 unlock the screen saver also when a central server is unavailable.
10101 This is possible by caching passwords and directory information (user
10102 and group attributes) locally, and the packages to do so are available
10103 in Debian. Here follow two recipes to set this up in Debian/Squeeze.
10104 It is also possible to set up in Debian/Lenny, but require more manual
10105 setup there because pam-auth-update is missing in Lenny.
</p
>
10107 <h2
>LDAP/Kerberos + nscd + libpam-ccreds + libpam-mklocaluser/pam_mkhomedir
</h2
>
10109 This is the traditional method with a twist. The password caching is
10110 provided by libpam-ccreds (version
10-
4 or later is needed on
10111 Squeeze), and the directory caching is done by nscd. The directory
10112 lookup and password checking is done using LDAP. If one want to use
10113 Kerberos for password checking the libpam-ldapd package can be
10114 replaced with libpam-krb5 or libpam-heimdal. If one is happy having a
10115 local home directory with the path listed in LDAP, one can use the
10116 pam_mkhomedir module from pam-modules to make this happen instead of
10117 using libpam-mklocaluser. A setup for pam-auth-update to enable
10118 pam_mkhomedir will have to be written until a fix for
10119 <a href=
"http://bugs.debian.org/
568577">bug #
568577</a
> is in the
10120 archive. Because I believe it is a bad idea to have local home
10121 directories using misleading paths like /site/server/partition/, I
10122 prefer to create a local user with the home directory in /home/. This
10123 is done using the libpam-mklocaluser package.

've been unable to get TLS

>The last few days I have been looking into the status of the LDAP
10304 directory in Debian Edu, and in the process I started to miss a GUI
10305 tool to browse the LDAP tree. The only one I was able to find in
10306 Debian/Squeeze and Lenny is
10307 <a href=
"http://luma.sourceforge.net/
">LUMA
</a
>, which has proved to
10308 be a great tool to get a overview of the current LDAP directory
10309 populated by default in Skolelinux. Thanks to it, I have been able to
10310 find empty and obsolete subtrees, misplaced objects and duplicate
10311 objects. It will be installed by default in Debian/Squeeze. If you
10312 are working with LDAP, give it a go. :)
</p
>
10314 <p
>I did notice one problem with it I have not had time to report to
10315 the BTS yet. There is no .desktop file in the package, so the tool do
10316 not show up in the Gnome and KDE menus, but only deep down in in the
10317 Debian submenu in KDE. I hope that can be fixed before Squeeze is
10318 released.
</p

10320 <p
>I have not yet been able to get it to modify the tree yet. I would
10321 like to move objects and remove subtrees directly in the GUI, but have
10322 not found a way to do that with LUMA yet. So in the mean time, I use
10323 <a href=

10329 <a href=

10330 useful GUI alternative. It seem like a good tool, but is unmaintained
10331 in Debian and got a RC bug keeping it out of Squeeze. Unless that
10332 changes, it will not be an option for Debian Edu based on Squeeze.

10347 <p

10398 I will only focus on their removal plans.
</p
>
10400 <p
>After installing a Gnome desktop and the laptop task, apt-get wants
10401 to remove
72 packages when dist-upgrading from Lenny to Squeeze. The
10402 surprising part is that it want to remove xorg and all
10403 xserver-xorg-video* drivers. Clearly not a good choice, but I am not
10404 sure why. When asking aptitude to do the same, it want to remove
129
10405 packages, but most of them are library packages I suspect are no
10406 longer needed. Both of them want to remove bluetooth packages, which
10407 I do not know. Perhaps these bluetooth packages are obsolete?
</p
>
10409 <p
>For KDE, apt-get want to remove
82 packages, among them kdebase
10410 which seem like a bad idea and xorg the same way as with Gnome. Asking
10411 aptitude for the same, it wants to remove
192 packages, none which are
10412 too surprising.
</p
>
10414 <p
>I guess the removal of xorg during upgrades should be investigated
10415 and avoided, and perhaps others as well. Here are the complete list
10416 of planned removals. The complete logs is available from the URL
10417 above. Note if you want to repeat these tests, that the upgrade test
10418 for kde+apt-get hung in the tasksel setup because of dpkg asking
10419 conffile questions. No idea why. I worked around it by using
10420 '<tt
>echo
>> /proc/
<em
>pidofdpkg
</em
>/fd/
0</tt
>' to tell dpkg to
10421 continue.

10567 <description><p
>The last few days I have done some upgrade testing in Debian, to
10568 see if the upgrade from Lenny to Squeeze will go smoothly. A few bugs
10569 have been discovered and reported in the process
10570 (
<a href=
"http://bugs.debian.org/
585410">#
585410</a
> in nagios3-cgi,
10571 <a href=
"http://bugs.debian.org/
584879">#
584879</a
> already fixed in
10572 enscript and
<a href=
"http://bugs.debian.org/
584861">#
584861</a
> in
10573 kdebase-workspace-data), and to get a more regular testing going on, I
10574 am working on a script to automate the test.
</p
>
10576 <p
>The idea is to create a Lenny chroot and use tasksel to install a
10577 Gnome or KDE desktop installation inside the chroot before upgrading
10578 it. To ensure no services are started in the chroot, a policy-rc.d
10579 script is inserted. To make sure tasksel believe it is to install a
10580 desktop on a laptop, the tasksel tests are replaced in the chroot
10581 (only acceptable because this is a throw-away chroot).
</p
>
10583 <p
>A naive upgrade from Lenny to Squeeze using aptitude dist-upgrade
10584 currently always fail because udev refuses to upgrade with the kernel
10585 in Lenny, so to avoid that problem the file /etc/udev/kernel-upgrade
10586 is created. The bug report
10587 <a href=
"http://bugs.debian.org/
566000">#
566000</a
> make me suspect
10588 this problem do not trigger in a chroot, but I touch the file anyway
10589 to make sure the upgrade go well. Testing on virtual and real
10590 hardware have failed me because of udev so far, and creating this file
10591 do the trick in such settings anyway. This is a
10592 <a href=
"http://www.linuxquestions.org/questions/debian-
26/failed-dist-upgrade-due-to-udev-config_sysfs_deprecated-nonsense-
804130/
">known
10593 issue
</a
> and the current udev behaviour is intended by the udev
10594 maintainer because he lack the resources to rewrite udev to keep
10595 working with old kernels or something like that. I really wish the
10596 udev upstream would keep udev backwards compatible, to avoid such
10597 upgrade problem, but given that they fail to do so, I guess
10598 documenting the way out of this mess is the best option we got for
10599 Debian Squeeze.

10726 Skolelinux-arkitekturen er laget for sentralisert drift og plassering

10728 Den er modellert på nettverks- og tjenerløsningen som brukes på

10730 driftstjenester. Dette er det heldigvis noen som har fått med seg, og
10731 jeg er glad for å kunne sitere fra en kommentar på den overnevnte

500 elevar. Dei store skulane har eigen tenar, for det er
10737 mest praktisk. Eg, som er driftsansvarleg for heile nettet, ser
10738 sjeldan dei tenarane fysisk, men at dei står der gjer skulane mindre
10739 avhengige av eksterne linjer som er trege eller dyre. Dei minste

>After a long break from debian-installer development, I finally
10912 found time today to return to the project. Having to spend less time
10913 working dependency based boot in debian, as it is almost complete now,
10914 definitely helped freeing some time.
</p
>
10916 <p
>A while back, I ran into a problem while working on Debian Edu. We
10917 include some firmware packages on the Debian Edu CDs, those needed to
10918 get disk and network controllers working. Without having these
10919 firmware packages available during installation, it is impossible to
10920 install Debian Edu on the given machine, and because our target group
10921 are non-technical people, asking them to provide firmware packages on
10922 an external medium is a support pain. Initially, I expected it to be
10923 enough to include the firmware packages on the CD to get
10924 debian-installer to find and use them. This proved to be wrong.
10925 Next, I hoped it was enough to symlink the relevant firmware packages
10926 to some useful location on the CD (tried /cdrom/ and
10927 /cdrom/firmware/). This also proved to not work, and at this point I
10928 found time to look at the debian-installer code to figure out what was
10929 going to work.
</p
>
10931 <p
>The firmware loading code is in the hw-detect package, and a closer
10932 look revealed that it would only look for firmware packages outside
10933 the installation media, so the CD was never checked for firmware
10934 packages. It would only check USB sticks, floppies and other
10935 "external
" media devices. Today I changed it to also look in the
10936 /cdrom/firmware/ directory on the mounted CD or DVD, which should
10937 solve the problem I ran into with Debian edu. I also changed it to
10938 look in /firmware/, to make sure the installer also find firmware
10939 provided in the initrd when booting the installer via PXE, to allow us
10940 to provide the same feature in the PXE setup included in Debian
10943 <p
>To make sure firmware deb packages with a license questions are not
10944 activated without asking if the license is accepted, I extended
10945 hw-detect to look for preinst scripts in the firmware packages, and
10946 run these before activating the firmware during installation. The
10947 license question is asked using debconf in the preinst, so this should
10948 solve the issue for the firmware packages I have looked at so far.

>Today, the last piece of the puzzle for roaming laptops in Debian
10961 Edu finally entered the Debian archive. Today, the new
10962 <a href=
"http://packages.qa.debian.org/libp/libpam-mklocaluser.html
">libpam-mklocaluser
</a

10963 package was accepted. Two days ago, two other pieces was accepted
10965 <a href=

10966 package needed by libpam-mklocaluser, and the
10967 <a href=

10968 passed NEW on Monday. In addition, the
10969 <a href=

">libpam-ccreds
</a
>
10970 package we need is in experimental (version
10-
4) since Saturday, and
10971 hopefully will be moved to unstable soon.
</p
>
10973 <p
>This collection of packages allow for two different setups for
10974 roaming laptops. The traditional setup would be using libpam-ccreds,
10975 nscd and libpam-mklocaluser with LDAP or Kerberos authentication,
10976 which should work out of the box if the configuration changes proposed
10977 for nscd in
<a href=
"http://bugs.debian.org/
485282">BTS report
10978 #
485282</a
> is implemented. The alternative setup is to use sssd with
10979 libpam-mklocaluser to connect to LDAP or Kerberos and let sssd take
10980 care of the caching of passwords and group information.
</p
>
10982 <p
>I have so far been unable to get sssd to work with the LDAP server
10983 at the University, but suspect the issue is some SSL/GnuTLS related
10984 problem with the server certificate. I plan to update the Debian
10985 package to version
1.2, which is scheduled for next week, and hope to
10986 find time to make sure the next release will include both the
10987 Debian/Ubuntu specific patches. Upstream is friendly and responsive,
10988 and I am sure we will find a good solution.
</p
>
10990 <p
>The idea is to set up the roaming laptops to authenticate using
10991 LDAP or Kerberos and create a local user with home directory in /home/
10992 when a usre in LDAP logs in via KDM or GDM for the first time, and
10993 cache the password for offline checking, as well as caching group
10994 memberhips and other relevant LDAP information. The
10995 libpam-mklocaluser package was created to make sure the local home
10996 directory is in /home/, instead of /site/server/directory/ which would
10997 be the home directory if pam_mkhomedir was used. To avoid confusion
10998 with support requests and configuration, we do not want local laptops
10999 to have users in a path that is used for the same users home directory
11000 on the home directory servers.
</p
>
11002 <p
>One annoying problem with gdm is that it do not show the PAM
11003 message passed to the user from libpam-mklocaluser when the local user
11004 is created. Instead gdm simply reject the login with some generic
11005 message. The message is shown in kdm, ssh and login, so I guess it is
11006 a bug in gdm. Have not investigated if there is some other message
11007 type that can be used instead to get gdm to also show the message.

11164 <description><p
>For some years now, I have wondered how we should handle laptops in
11165 Debian Edu. The Debian Edu infrastructure is mostly designed to
11166 handle stationary computers, and less suited for computers that come
11169 <p
>Now I finally believe I have an sensible idea on how to adjust
11170 Debian Edu for laptops, by introducing a new profile for them, for
11171 example called Roaming Workstations. Here are my thought on this.
11172 The setup would consist of the following:
</p
>
11176 <li
>During installation, the user name of the owner / primary user of
11177 the laptop is requested and a local home directory is set up for
11178 the user, with uid and gid information fetched from the LDAP
11179 server. This allow the user to work also when offline. The
11180 central home directory can be available in a subdirectory on
11181 request, for example mounted via CIFS. It could be mounted
11182 automatically when a user log in while on the Debian Edu network,
11183 and unmounted when the machine is taken away (network down,
11184 hibernate, etc), it can be set up to do automatic mounting on
11185 request (using autofs), or perhaps some GUI button on the desktop
11186 can be used to access it when needed. Perhaps it is enough to use
11187 the fish protocol in KDE?
</li
>
11189 <li
>Password checking is set up to use LDAP or Kerberos
11190 authentication when the machine is on the Debian Edu network, and
11191 to cache the password for offline checking when the machine unable
11192 to reach the LDAP or Kerberos server. This can be done using
11193 <a href=
"http://www.padl.com/OSS/pam_ccreds.html
">libpam-ccreds
</a
>
11194 or the Fedora developed
11195 <a href=
"https://fedoraproject.org/wiki/Features/SSSD
">System
11196 Security Services Daemon
</a
> packages.
</li
>
11198 <li
>File synchronisation with the central home directory is set up
11199 using a shared directory in both the local and the central home
11200 directory, using unison.
</li
>
11202 <li
>Printing should be set up to print to all printers broadcasting
11203 their existence on the local network, and should then work out of
11204 the box with CUPS. For sites needing accurate printer quotas, some
11205 system with Kerberos authentication or printing via ssh could be
11206 implemented.
</li
>
11208 <li
>For users that should have local root access to their laptop,
11209 sudo should be used to allow this to the local user.
</li
>
11211 <li
>It would be nice if user and group information from LDAP is
11212 cached on the client, but given that there are entries for the
11213 local user and primary group in /etc/, it should not be needed.
</li
>
11217 <p
>I believe all the pieces to implement this are in Debian/testing at
11218 the moment. If we work quickly, we should be able to get this ready
11219 in time for the Squeeze release to freeze. Some of the pieces need
11220 tweaking, like libpam-ccreds should get support for pam-auth-update
11221 (
<a href=
"http://bugs.debian.org/
566718">#
566718</a
>) and nslcd (or
11222 perhaps debian-edu-config) should get some integration code to stop
11223 its daemon when the LDAP server is unavailable to avoid long timeouts
11224 when disconnected from the net. If we get Kerberos enabled, we need
11225 to make sure we avoid long timeouts there too.

11238 NUUG presentation
</a
> about Kerberos was inspiring, and reminded me
11239 about the need to start using Kerberos in Skolelinux. Setting up a
11240 Kerberos server seem to be straight forward, and if we get this in
11241 place a long time before the Squeeze version of Debian freezes, we
11242 have a chance to migrate Skolelinux away from NFSv3 for the home
11243 directories, and over to an architecture where the infrastructure do
11244 not have to trust IP addresses and machines, and instead can trust
11245 users and cryptographic keys instead.
</p
>
11247 <p
>A challenge will be integration and administration. Is there a
11248 Kerberos implementation for Debian where one can control the
11249 administration access in Kerberos using LDAP groups? With it, the
11250 school administration will have to maintain access control using flat
11251 files on the main server, which give a huge potential for errors.
</p
>
11253 <p
>A related question I would like to know is how well Kerberos and
11254 pam-ccreds (offline password check) work together. Anyone know?
</p
>
11256 <p
>Next step will be to use Kerberos for access control in Lwat and
11257 Nagios. I have no idea how much work that will be to implement. We
11258 would also need to document how to integrate with Windows AD, as such
11259 shared network will require two Kerberos realms that need to cooperate
11260 to work properly.
</p
>
11262 <p
>I believe a good start would be to start using Kerberos on the
11263 skolelinux.no machines, and this way get ourselves experience with
11264 configuration and integration. A natural starting point would be
11265 setting up ldap.skolelinux.no as the Kerberos server, and migrate the
11266 rest of the machines from PAM via LDAP to PAM via Kerberos one at the
11269 <p
>If you would like to contribute to get this working in Skolelinux,
11270 I recommend you to see the video recording from yesterdays NUUG
11271 presentation, and start using Kerberos at home. The video show show
11272 up in a few days.

>6 years ago, as part of the Debian Edu development I am involved
11282 in, I asked for a hook in the kdm and gdm setup to run scripts as root
11283 when the user log out. A bug was submitted against the xfree86-common
11284 package in
2004 (
<a href=
"http://bugs.debian.org/
230422">#
230422</a

11285 and revisited every time Debian Edu was working on a new release.
11286 Today, this finally paid off.
</p
>
11288 <p
>The framework for this feature was today commited to the git
11289 repositry for the xorg package, and the git repository for xdm has
11290 been updated to use this framework. Next on my agenda is to make sure
11291 kdm and gdm also add code to use this framework.
</p
>
11293 <p
>In Debian Edu, we want to ability to run commands as root when the
11294 user log out, to get rid of runaway processes and do general cleanup
11295 after a user. With this framework in place, we finally can do that in
11296 a generic way that work with all display managers using this
11297 framework. My goal is to get all display managers in Debian use it,
11298 similar to how they use the Xsession.d framework today.

>One of the new features in the next Debian/Lenny based release of
11330 Debian Edu/Skolelinux, which is scheduled for release in the next few
11331 days, is automatic configuration of the service monitoring system
11332 Nagios. The previous release had automatic configuration of trend
11333 analysis using Munin, and this Lenny based release take that a step
11336 <p
>When installing a Debian Edu Main-server, it is automatically
11337 configured as a Munin and Nagios server. In addition, it is
11338 configured to be a server for the
11339 <a href=
"http://wiki.debian.org/DebianEdu/HowTo/SiteSummary
">SiteSummary
11340 system
</a
> I have written for use in Debian Edu. The SiteSummary
11341 system is inspired by a system used by the University of Oslo where I
11342 work. In short, the system provide a centralised collector of
11343 information about the computers on the network, and a client on each
11344 computer submitting information to this collector. This allow for
11345 automatic information on which packages are installed on each machine,
11346 which kernel the machines are using, what kind of configuration the
11347 packages got etc. This also allow us to automatically generate Munin
11348 and Nagios configuration.
</p
>
11350 <p
>All computers reporting to the sitesummary collector with the
11351 munin-node package installed is automatically enabled as a Munin
11352 client and graphs from the statistics collected from that machine show
11353 up automatically on http://www/munin/ on the Main-server.
</p
>
11355 <p
>All non-laptop computers reporting to the sitesummary collector are
11356 automatically monitored for network presence (ping and any network
11357 services detected). In addition, all computers (also laptops) with
11358 the nagios-nrpe-server package installed and configured the way
11359 sitesummary would configure it, are monitored for full disks, software
11360 raid status, swap free and other checks that need to run locally on
11361 the machine.
</p
>
11363 <p
>The result is that the administrator on a school using Debian Edu
11364 based on Lenny will be able to check the health of his installation
11365 with one look at the Nagios settings, without having to spend any time
11366 keeping the Nagios configuration up-to-date.
</p
>
11368 <p
>The only configuration one need to do to get Nagios up and running
11369 is to set the password used to get access via HTTP. The system
11370 administrator need to run
"<tt
>htpasswd /etc/nagios3/htpasswd.users
11371 nagiosadmin
</tt
>" to create a nagiosadmin user and set a password for
11372 it to be able to log into the Nagios web pages. After that,
11373 everything is taken care of.

11446 30 people participated, and I believe it was a great environment to
11447 get to know the Skolelinux system. Walter Bender, involved in the
11448 development of the Sugar educational platform, presented his stuff and
11449 also helped me improve my OLPC installation. He also showed me that
11450 his Turtle Art application can be used in standalone mode, and we
11451 agreed that I would help getting it packaged for Debian. As a
11452 standalone application it would be great for Debian Edu. We also
11453 tried to get the video conferencing working with two OLPCs, but that
11454 proved to be too hard for us. The application seem to need more work

11507 Et langt steg videre for Debian-prosjektet, og en rekke nye
11508 programpakker blir nå tilgjengelig for de av oss som bruker den
11509 stabile utgaven av Debian. Neste steg er nå å få

11513 slippes løs på skolene. Takk til alle debian-utviklerne som har
11514 gjort dette mulig. Endelig er f.eks. fungerende avhengighetsstyrt

>Etter flere års mislykkede forsøk på å skrive om byggesystemet for
11526 <a href=
"http://no.speling.org/
">den norske stavekontrollen for bokmål
11527 og nynorsk
</a
> til å ikke bruke bindestrek som ordskillemarkør, lyktes jeg
11528 endelig første juledag. Bruken av bindestrek som ordskillemarkør har
11529 gjort det umulig å få med ord med bindestrek i
11530 stavekontrolldatagrunnlaget, slik at ord som e-post og CD-spiller ikke
11531 kunne godtas av stavekontrollen. Hadde litt tid til overs å bruke på
11532 stavekontrollen, og satte meg ned med to kopier av byggsystemet og en
11533 liten testdatafil, og byttet ut - med = på utvalgte steder i
11534 byggsystemet og datafilen helt til jeg fikk samme resultat med det
11535 gamle og det nye byggsystemet. Dette tror jeg var forsøk
4, der de
11536 foregående har feilet uten at jeg klarte å forstå hvorfor. Det sier
11537 kanskje litt om kompleksiteten i det originale byggsystemet som Rune
11538 Kleveland laget i sin tid.
</p
>
11540 <p
>Etter å ha endret byggsystemet, var neste steg å importere ordene
11541 med bindestrek. Vi har en rekke slike i databasene for
11542 <a href=
"http://tyge.sslug.dk/~korsvoll/nb.speling.org/htdocs/
">bokmål
</a
>
11544 <a href=
"http://tyge.sslug.dk/~korsvoll/nn.speling.org/htdocs/
">nynorsk
</a
>
11545 for korrektur av datagrunnlaget for stavekontrollen, og etter importen
11546 skulle nå
10350 nye ord bli godkjent som korrekt stavede ord av
11547 stavekontrollen.

>This weekend we had a small developer gathering for Debian Edu in
11557 Oslo. Most of Saturday was used for the general assemly for the
11558 member organization, but the rest of the weekend I used to tune the
11559 LTSP installation. LTSP now work out of the box on the
10-network.
11560 Acer Aspire One proved to be a very nice thin client, with both
11561 screen, mouse and keybard in a small box. Was working on getting the
11562 diskless workstation setup configured out of the box, but did not
11563 finish it before the weekend was up.
</p

11565 <p
>Did not find time to look at the
4 VGA cards in one box we got from
11566 the Brazilian group, so that will have to wait for the next
11567 development gathering. Would love to have the Debian Edu installer
11568 automatically detect and configure a multiseat setup when it find one
11569 of these cards.

>Recently I have spent some time evaluating the multimedia browser
11579 plugins available in Debian Lenny, to see which one we should use by
11580 default in Debian Edu. We need an embedded video playing plugin with
11581 control buttons to pause or stop the video, and capable of streaming
11582 all the multimedia content available on the web. The test results and
11583 notes are available on
11584 <a href=
"http://wiki.debian.org/DebianEdu/BrowserMultimedia
">the
11585 Debian wiki
</a
>. I was surprised how few of the plugins are able to
11586 fill this need. My personal video player favorite, VLC, has a really
11587 bad plugin which fail on a lot of the test pages. A lot of the MIME
11588 types I would expect to work with any free software player (like
11589 video/ogg), just do not work. And simple formats like the
11590 audio/x-mplegurl format (m3u playlists), just isn
't supported by the
11591 totem and vlc plugins. I hope the situation will improve soon. No
11592 wonder sites use the proprietary Adobe flash to play video.
