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

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

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

>
61 ldapvi --ldap-conf -ZD

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

86 <p
>The last step to remember is to mount the relevant mount points in
87 tjener.intern by adding them to /etc/fstab, creating the mount
88 directories using mkdir and running
"mount -a

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

103 project
</a

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

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

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

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

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

>A few hours ago, the announcement for the first stable release of
470 Debian Edu Wheezy went out from the Debian publicity team. The
471 complete announcement text can be found at
472 <a href=
"http://www.debian.org/News/
2013/

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

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

578 <p
>Alpha based installations should reinstall or downgrade the
579 versions of gosa and libpam-mklocaluser to the ones used in this beta

1) Keep
582 gosa.conf and edit this file as outlined on the mailing list. (
2)
583 Accept the new version of gosa.conf and replace both contained admin
584 password placeholders with the password hashes found in the old one
585 (backup copy!). In both cases all users need to change their password

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

>In the
<a href=
"http://www.skolelinux.org/
">Debian Edu /
998 Skolelinux
</a
> project, we include a post-installation test suite,
999 which check that services are running, working, and return the
1000 expected results. It runs automatically just after the first boot on
1001 test installations (using test ISOs), but not on production
1002 installations (using non-test ISOs). It test that the LDAP service is
1003 operating, Kerberos is responding, DNS is replying, file systems are
1004 online resizable, etc, etc. And it check that the PXE service is
1005 configured, which is the topic of this post.
</p
>
1007 <p
>The last week I
've fixed the DVD and USB stick ISOs for our Debian
1008 Edu Wheezy release. These ISOs are supposed to be able to install a
1009 complete system without any Internet connection, but for that to
1010 happen all the needed packages need to be on them. Thanks to our test
1011 suite, I discovered that we had forgotten to adjust our PXE setup to
1012 cope with the new names and paths used by the netboot d-i packages.
1013 When Internet connectivity was available, the installer fall back to
1014 using wget to fetch d-i boot images, but when offline it require
1015 working packages to get it working. And the packages changed name
1016 from debian-installer-
6.0-netboot-$arch to
1017 debian-installer-
7.0-netboot-$arch, we no longer pulled in the
1018 packages during installation. Without our test suite, I suspect we
1019 would never have discovered this before release. Now it is fixed
1020 right after we got the ISOs operational.
</p
>
1022 <p
>Another by-product of the test suite is that we can ask system
1023 administrators with problems getting Debian Edu to work, to run the
1024 test suite using
<tt
>/usr/sbin/debian-edu-test-install
</tt
> and see if
1025 any errors are detected. This usually pinpoint the subsystem causing
1026 the problem.

1046 #debian-edu

1047 worked. We answered as good as we could, and even convinced him to
1048 help us with translations. And today I managed to get an interview
1049 with him, to learn more about him.

</strong

1053 <p
>I
'm a
25 year old free software enthusiast, living in Romania,
1054 which is also my country of origin. Back in
2009, at a New Year
's Eve
1055 party, I had a very nice
<strike
>beer
</strike
> discussion with a
1056 friend, when we realized we have no organised Debian community in our
1057 country. A few days later, we put together the infrastructure for such
1058 community and even gathered a nice Debian-ish crowd. Since then, I
1059 began my quest as a free software hacker and activist and I am
1060 constantly trying to cover as much ground as possible on that
1063 <p
>A few years ago I founded a small web development company, which
1064 provided me the flexible schedule I needed so much for my
1065 activities. For the last
13 months, I have been the Technical Director
1066 of
<a href=
"http://ceata.org/
">Fundația Ceata
</a
>, which is a free
1067 software activist organisation endorsed by the FSF and the FSFE, and
1068 the only one we have in our country.
</p
>
1070 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
1071 project?
</strong
></p
>
1073 <p
>The idea of participating in the Debian Edu project was a surprise
1074 even to me, since I never used it before I began getting involved in
1075 it. This year I had a great opportunity to deliver a talk on
1076 educational software, and I knew immediately where to look. It was a
1077 love at first sight, since I was previously involved with some of the
1078 technologies the project incorporates, and I rapidly found a lot of
1079 ways to contribute.
</p
>
1081 <p
>My first contributions consisted in translating the installer and
1082 configuration dialogs, then I found some bugs to squash (I still
1083 haven
't fixed them yet though), and I even got my eyes on some other
1084 areas where I can prove myself helpful. Since the appetite for free
1085 software in my country is pretty low, I
'll be happy to be the first
1086 one around here advocating for the project
's adoption in educational
1087 environments, and maybe even get my hands dirty in creating a flavour
1088 for our own needs. I am not used to make very advanced plannings, so
1089 from now on, time will tell what I
'll be doing next, but I think I
1090 have a pretty consistent starting point.
</p

1092 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
1093 Edu?
</strong
></p
>
1095 <p
>Not a long time ago, I was in the position of configuring and
1096 maintaining a LDAP server on some Debian derivative, and I must say it
1097 took me a while. A long time ago, I was maintaining a bigger
1098 Samba-powered infrastructure, and I must say I spent quite a lot of
1099 time on it. I have similar stories about many of the services included
1100 with Skolelinux, and the main advantage I see about it is the
1101 out-of-the box availability of them, making it quite competitive when
1102 it comes to managing a school
's network, for example.
</p
>
1104 <p
>Of course, there is more to say about Skolelinux than the
1105 availability of the software included, its flexibility in various
1106 scenarios is something I can
't wait to experiment
"into the wild
" (I
1107 only played with virtual machines so far). And I am sure there is a
1108 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
1112 Edu?
</strong
></p
>
1114 <p
>As usual, when it comes to Debian Blends, I see as the biggest
1115 disadvantage the lack of a numerous team dedicated to the
1116 project. Every day I see the same names in the changelogs, and I have
1117 a constantly fear of the bus factor in this story. I
'd like to see
1118 Debian Edu advertised more as an entry point into the Debian
1119 ecosystem, especially amongst newcomers and students. IMHO there are a
1120 lot low-hanging fruits in terms of bug squashing, and enough
1121 opportunities to get the feeling of the Debian Project
's dynamics. Not
1122 to mention it
's a very fun blend to work on!
</p
>
1124 <p
>Derived from the previous statement, is the delay in catching up
1125 with the main Debian release and documentation. This is common though
1126 to all blends and derivatives, but it
's an issue we can all work
1129 <p
><strong
>Which free software do you use daily?
</strong
></p
>
1131 <p
>I can hardly imagine myself spending a day without Vim, since my
1132 daily routine covers writing code and hacking configuration files. I
1133 am a fan of the Awesome window manager (but I also like the
1134 Enlightenment project a lot!),
1135 <a href=
"http://www.claws-mail.org/

1136 use and very configurable behaviour. Recently I fell in love with
1137 <a href=
"https://launchpad.net/redshift
">Redshift
</a
>, which helps me
1138 get through the night without headaches. Of course, there is much more
1139 stuff in this bag, but I
'll need a blog on my own for doing this!

1142 get schools to use free software?
</strong

1144 <p
>Well, on this field, I cannot do much more than experiment right
1145 now. So, being far from having a recipe for success, I can only assume
1150 <li
>schools would like to get rid of proprietary software
</li
>
1152 <li
>students will love the openness of the system, and will want to
1153 experiment with it - maybe we need to harvest the native curiosity
1154 of teenagers more?
</li
>
1156 <li
>there is no
"right one
" when it comes to strategies, but it would
1157 be useful to have some success stories published somewhere, so
1158 other can get some inspiration from them (I know I
'd promote
1161 <li
>more active promotion - talks, conferences, even small school
1162 lectures can do magical things if they encounter at least one
1163 person interested. Who knows who that person might be? ;-)
</li
>
1167 <p
>I also see some problems in getting Skolelinux into schools; for
1168 example, in our country we have a great deal of corruption issues, so
1169 it might be hard(er) to fight against proprietary solutions. Also,
1170 people who relied on commercial software for all their lives, would be
1171 very hard to convert against their will.

1200 <p

've been somewhat familiar with the project before, but I think my
1201 first direct exposure to the project was when I met Petter
1202 [Reinholdtsen] and Knut [Yrvin] at the Edubuntu summit in
2005 in
1203 London. They provided great feedback that helped the bootstrapping of
1204 Edubuntu. Back then Edubuntu (and even Ubuntu) was still very new and
1205 it was great getting input from people who have been around longer. I
1206 was also still very excitable and said yes to everything and to this
1207 day I have a big todo list backlog that I
'm catching up with. I think
1208 over the years the relationship between Edubuntu and Debian-Edu has
1209 been gradually improving, although I think there
's a lot that we could
1210 still improve on in terms of working together on packages. I
'm sure
1211 we
'll get there one day.

1216 <p
>Debian itself already has so many advantages. I could go on about
1217 it for pages, but in essence I love that it
's a very honest project
1218 that puts its users first with no hidden agendas and also produces
1219 very high quality work.
</p
>
1221 <p
>I think the advantage of Debian Edu is that it makes many common
1222 set-up tasks simpler so that administrators can get up and running
1223 with a lot less effort and frustration. At the same time I think it
1224 helps to standardise installations in schools so that it

1234 <p
>The biggest disadvantage I can think of is lack of manpower. The
1235 project could do so much more if there were more good contributors. I
1236 think some of the problems are external too. Free software and free
1237 content in education is a no-brainer but it takes some time to catch
1238 on. When you
've been working with the same proprietary eco-system for
1239 years and have gotten used to it, it can be hard to adjust to some
1240 concepts in the free software world. It would be nice if there were
1241 more Debian Edu consultants across the world. I
'd love to be one
1242 myself but I
'm already so over-committed that it
's just not possible
1243 currently.

1245 <p
>I think the best short-term solution to that large-scale problem is
1246 for schools to be pro-active and share their experiences and grow
1247 their skills in-house. I
'm often saddened to see how much money
1248 educational institutions spend on
3rd party solutions that they don
't
1249 have access to after the service has ended and they could
've gotten so
1250 much more value otherwise by being more self-sustainable and
1251 autonomous.

1255 <p

1256 Windows free for years but started dual-booting again last year for
1257 some games which help me focus and relax (Starcraft II in
1258 particular). Gaming support on Linux is improving in leaps and bounds

'm taking some refuge in Xfce
1264 while I figure that out. I like tools that keep things simple. I enjoy
1265 Python and shell scripting. I went to an Arduino workshop recently and

">Debian Edu, also known as
1318 Skolelinux
</a
>, is a Linux distribution based on Debian providing an
1319 out-of-the box environment of a completely configured school
1320 network. Immediately after installation a school server running all
1321 services needed for a school network is set up just waiting for users
1322 and machines being added via GOsa², a comfortable Web-UI. A netbooting
1323 environment is prepared using PXE, so after initial installation of
1324 the main server from CD, DVD or USB stick all other machines can be
1325 installed via the network. The provided school server provides LDAP
1326 database and Kerberos authentication service, centralized home
1327 directories, DHCP server, web proxy and many other services. The

1494 me also was the fact that among the software installed by default,
1495 there were many
"traditional

1496 to count, to program... but also software to develop creativity and

1521 <p
>Maybe the lack of manpower to do lobbying on the

1523 not have all the elements to evaluate properly free software
1524 solutions. The fact that support by a company may be difficult to find
1525 is probably a problem if the school does not have IT personnel.

1527 <p

1530 companies providing support for Debian Edu, like Germany or
1531 Norway. This list is easy to find readily from the manual. However,
1532 for other countries, like France, the list is empty. I guess that
1533 consultants proposing support for Debian would be able to provide some
1534 support for Debian Edu as well.

1749 <p
>Jeg heter Nirosan Thiyagalingam. Jeg er
24 år og studerer
1750 dataingeniør studiet ved Høgskolen i Sør Trøndelag. Interessen for
1751 data har siden ung alder vært tilstede og jeg har i tillegg alltid
1752 vært glad i å lære nye ting. Med teknologi som endres svært hurtig er
1753 det alltid noe nytt å lære. Noe som igjen har gjort det svært
1754 interessant å følge med på utviklingen. Jeg valgte dataingeniør
1755 studiet grunnet ønske om å lære enda mer om programmering og utvikling
1756 av store systemer.
</p
>
1758 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
1760 <p
>Skolelinux prosjektet hørte jeg først om i media. Men det var først
1761 når jeg skulle velge bacheloroppgave at jeg fattet mer interesse for
1762 prosjektet. Et enkelt søk på nettet førte meg til skolelinux sine
1763 hjemmesider. Informasjonen jeg fant der gjorde meg enda nysgjerrig og
1764 jeg valgte derfor en oppgave som gikk ut på å få en
1765 <a href=
"http://www.raspberrypi.org
">Raspberry PI
</a
>. Altså en
1766 ultra-billig datamaskin til å kjøre Debian Edu på lik linje med
1767 vanlige datamaskiner. I løpet av prosjektet ble det gjort mye
1768 forskning på nettet. Det var mye jeg måtte forstå rundt hvordan
1769 operativsystemet Linux fungerte før jeg kunne angripe
1770 problemet. Prøvde først å finne ut hvordan man kunne transformere en
1771 vanlig installasjon av Skolelinux til Raspberry PI, men dette var
1772 altfor vanskelig å jeg endte opp med mer spørsmål enn svar. Det ble
1773 videre opprettet kontakt med Skolelinux utviklere på IRC der jeg fikk
1774 diskutert hvilken retning jeg burde gå for å få til en fullverdig
1775 løsning. Det ble bestemt at jeg skulle gå for å først installere
1776 <a href=
"http://www.raspbian.org/
">Raspian
</a
>. Dette er et
1777 operativsystem basert på Debian spesiallaget for Raspberry Pi sin
1778 maskinvare. Nå som Debian var installert på datamaskinen gjenstod det
1779 å installere de nødvendige Skolelinux pakkene for å få til et
1780 fullverdig system. Disse pakkene ble installert manuelt i første
1781 omgang, men ble senere installert automatisk via et script som Petter
1782 Reinholdtsen laget. Dette scriptet er så enkel å bruke at man er i
1783 gang med installasjonen i løpet av bare
5 minutter. Ikke nok med det,
1784 alt skjer helt automatisk. Alt i alt er jeg veldig fornøyd med
1785 resultatet av installasjonsprosessen. Raspberry Pi er en veldig svak
1786 maskin og det merkes godt når man har installert Skolelinux på
1787 den. Video og
3D-rendering fungerer utrolig dårlig, men nettsurfing og
1788 kontorprogrammer fungerer godt. Det kan derfor konkluderes med at
1789 datamaskinen er egnet for enkle oppgaver.
1791 <p
>Jeg syns det er viktig påpeke at dette kun er startfasen av en slik
1792 løsning. På markedet finnes det nå maskiner som har bedre hardware enn
1793 Raspberry Pi. Det er store muligheter for at man kan klare å
1794 installere Skolelinux på disse også, og da forsvinner nok mest
1795 sannsynlig ytelsesproblemene med Video og
3D rendering også.
</p
>
1797 <p
>Det ble også prøvd med en løsning som gjorde at Raspberry Pi
1798 fungerte som en tynnklient. Denne løsningen hadde langt bedre ytelse
1799 med tanke på hastighet og brukeropplevelse. Men også her var video og
1800 3D rendering dårlig. Det ble brukt en liten Linux distribusjon kalt
1801 <a href=

">BerryTerminal
</a
> for å få til
1804 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
1806 <p
>Fordelen med Skolelinux er mange. At det er gratis er en stor
1807 fordel, men at det er så mange som er med på å utvikle det og
1808 vedlikeholde det er en enda større fordel. Allerede før jeg startet
1809 med prosjektet så jeg mange fordeler, og når jeg nærmet meg sluttfasen
1810 så jeg langt flere. At prosjektet skulle inneha en så høy kvalitet
1811 hadde jeg aldri trodd. En vanlig Skolelinux installasjon har de
1812 nødvendige programmene og funksjonen som både små og store skoler i
1813 tillegg til organisasjoner kan klare seg med. At prosjektet tilbyr en
1814 så komplett løsning er en kjempefordel. Installasjonen er knirkefri
1815 og det er svært enkelt å installere og komme i gang.
</p
>
1817 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
1819 <p
>Ulempene jeg ser med prosjektet er ryddigheten av websidene. Selv
1820 om websidene er enkle og konsise er det allikevel ikke appellerende i
1821 like stor grad som for eksempel
1822 <a href=
"http://www.ubuntu.com
">Ubuntu
</a
> sine sider. Deres side
1823 tilbyr, i tillegg til godt design og presentasjon, en nettbasert
1824 emulator av deres operativsystem. Dette er en stor fordel slik jeg ser
1825 det. Bortsett fra dette ser jeg absolutt ingen ulemper med
1826 Skolelinux-prosjektet.

1828 <p
><strong
>Hvilken fri programvare bruker du til daglig?

1830 <p
>Til daglig er jeg en flittig bruker av det åpne media
1831 sentersystemet
<a href=
"http://xbmc.org/
">XBMC
</a
>. Det enorme
1832 samfunnet rundt dette prosjektet har gjort dette til et program som
1833 dekker alles behov. Man kan tilpasse det akkurat slik man vil både med
1834 tanke på utseende og funksjoner ved installere plug-ins eller
1837 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
1838 skoler til å ta i bruk fri programvare?
</strong
></p
>
1840 <p
>Strategien som burde brukes sett fra mine øyne er
1841 markedsføring. Jeg er sikker på at om flere skoler fikk et lite innsyn
1842 i hvor bra Skolelinux er så ville de ikke nølt med å gå over fra noe
1843 annet som koster de store summer. At skolelinux til de grader tilbyr
1844 en så komplett løsning bure komme frem. Enten via reklamekampanjer
1845 eller ved å sende ut folk til skoler for så å la skolenettverk
1846 ansvarlige få teste ut hvordan Skolelinux fungerer i praksis. Om det
1847 i tillegg ble utviklet gode websider og en emulator for å la brukere
1848 prøve operativsystemet ville nok dette ha styrket inntrykket
1849 betraktelig.

1943 <p
>Debian Edu, also known as Skolelinux, is a Linux distribution based
1944 on Debian providing an out-of-the box environment of a completely
1945 configured school network. Immediatly after installation a school
1946 server running all services needed for a school network is set up just
1947 waiting for users and machines being added via GOsa², a comfortable
1948 Web-UI. A netbooting environment is prepared using PXE, so after
1949 initial installation of the main server from CD, DVD or USB stick all
1950 other machines can be installed via the network.

2104 out-of-the box environment of a completely configured school
2105 network. Immediatly after installation a school server running all
2106 services needed for a school network is set up just waiting for users
2107 and machines being added via GOsa², a comfortable Web-UI. A netbooting
2108 environment is prepared using PXE, so after initial installation of
2109 the main server from CD, DVD or USB stick all other machines can be
2110 installed via the network.

6. He installed the standalone profile and
2236 the video show a walk-through of of the menu content, demonstration of
2237 a few programs and his view of our distribution.
</p
>
2239 <p
>There is also some really nice quotes (transcribed by me, might
2240 have heard wrong). While looking thought the Graphics menu:
</p
>
2243 "Basically everything you ever need in a school environment.
"
2246 <p
>And as a general evaluation of the entire distribution:
</p
>
2249 "So, yeah, a bit bloated. It kept all the Debian stuff in there, just
2250 to keep it nice and GNU. So, I do not want to go on about it, but
2251 lets give it
7 out of
10. I am not going to use it. That is because
2252 I am not deploying a school network. There may be some mythical
2253 feature to help you deploy Skolelinux on a school network.
"
2256 <p
>To bad he did not test the server profile, and discovered the PXE
2257 installation option. It make it possible to install only the main
2258 server from CD, and the rest of the machines via the net, and might be
2259 considered the mythical feature he talk about. :)
</p
>
2261 <p
>While looking through the menus, there is also this funny comment
2262 about the part of the K menu generated from the Debian menu subsystem:
2265 "[The K menu] have a special Debian section for software that no-one
2266 is going to look at, because it contain lots of junky stuff that you
2267 actually don
't need in the education distribution, but have just been
2268 included because it isn
't stripped out for some reason.
"
2271 <p
>I guess it is yet another argument for merging the Debian menu and
2272 Gnome/KDE desktop menu entries into
2273 <a href=
"http://wiki.debian.org/Proposals/DebianMenuUsingDesktopEntries
">one
2274 consistent menu system
</a
> instead of two incomplete and partly
2275 inconsistent menu systems.

2398 er Fagbrev som it-teknikker, samt nokre fag innen nettverk- og
2399 server-drift frå HiST og NTNU. Dagleg arbeid består i oppsett av nye
2400 maskiner og hjelp til sluttbrukere, samt oppsett og vedlikehold av eit
2401 vidt spekter av fagsystemer ute hjå kunder. Erfaring med Skolelinux
2402 har eg hatt i forbindelse med drifting av

><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
2410 <p
>Eg kom i kontakt med Skolelinux-prosjektet via ein artikkel i eit
2411 fagblad, som eg ikkje lenger hugsar namnet på. I og med at eg allereie
2412 hadde pusla med nettverk for ein annan skule, fatta eg straks
2413 interesse for prosjektet.
</p
>
2415 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
2417 <p
>Fordelane med Skolelinux er sentralisert administrasjon og svært
2418 mange gode verktøy «ut av boksen». Veldig kjekt å kunne drifte
60
2419 klientar med berre å «bry» seg med ein server. Levetid for systemets
2420 hardware er og ein veldig fin effekt. I tillegg kjem fordelar som økt
2421 sikkerhet og mindre lisenskostnader. Etter min erfaring er det og
2422 mykje mindre driftskostnader med eit slikt system enn konkurrerande
2423 system, pga enkelhet med sentralisert administrasjon. På grunn av at
2424 Skolelinux er basert på Debian er det òg svært stabilt.
</p
>
2426 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
2428 <p
>Ulemper er mangel på vilje til å følge standarer ute i markedet,
2429 som fører til mangel på støtte til nokre mykje brukte ting. Flash og
2430 Java er typiske eksempel. Sidan Debian satsar på stabilitet framfor å
2431 ha nyeste pakke av eit program, kan ein i nokre tilfeller kome borti
2432 at program vert «for gamle». Det er spesielt nettlesaren som er
2433 utsett. Mangel på vilje til å utvikle pedagogisk programvare, i Noreg,
2434 for «alle» platformer fører òg til noko hovudbry.
</p
>
2436 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
2438 <p
>Til dagleg bruker eg svært mange forskjellige «fri programvare»
2439 program. Firefox, Thunderbird, Freecommander, ImgBurn, Clonezilla,
2440 OCS inventory, Icinga, Skolelinux, SystemRescueCD og mykje meir.
</p
>
2442 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
2443 skoler til å ta i bruk fri programvare?
</strong
></p
>
2445 <p
>Strategisk må ein fokusere på at sluttbruker eigentleg ikkje er så
2446 fokusert på at det er fri programvare men at det skal «berre fungere».
2447 Gjer det enkelt å bruker og ikkje minst å administrere. For Skolelinux
2448 sin del må ein få eit betre fokus på overganger. Utbytting av servere
2449 må gå meir automatisk, import og eksport av brukerbase og maskinbase
2450 med meir må kunne gå enkelt og oppgradering til neste versjon må bli
2451 mykje meir automatisk og gjennomtesta. Ein må unngå at ein må sette
2452 opp frå start når ein byter ut ein server eller oppgraderer til neste
2453 versjon. For å få Skolelinux til å bli eit betre alternativ for skular
2454 må ein ha fokus på nettlesaren. Denne må bli «up to date» og støtte
2455 dei protokollar og tillegg som vert brukt av forlag med meir. Etter
2456 kvart som meir og meir blir flytta ut i «skya» vert dette viktigare og
2457 viktigare. Ein kunne ynskje og jobbe for at forlag med fleire tar i
2458 bruk opne standarer, men inntil det skjer, må systemet kunne brukast
2459 mot desse fagsystema.
</p
>
2461 <p
>For meg har prosjektet med Skolelinux vore ein svært artig og
2462 lærerik prosess. Miljøet rundt er ikkje enormt stort, dog stort nok,
2463 men det er svært hjelpevillig og engasjert.

2563 welcome to Angela Fuß. :)
</p

2565 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
2567 <p
>I am a
39-year-old woman living in the very north of Germany near
2568 Denmark. I live in a patchwork family with
"my man
" Mike Gabriel, my
2569 two daughters, Mikes daughter and Mikes and my rather newborn son.
2571 <p
>At the moment - because of our little baby - I am spending most of
2572 the day by being a caring and organising mom for all the kids.
2573 Besides that I am really involved into and occupied with several inner
2574 growth processes: New born souls always bring the whole familiar
2575 system into movement and that needs time and focus ;-). We are also
2576 in the middle of buying a house and moving to it.
</p
>
2578 <p
>In
2013 I will work again in my job in a German foundation for
2579 nature conservation. I am doing public relation work there. Besides
2580 that - and that is the connection to Skolelinux / Debian Edu - I am
2581 working in our own school project
"IT-Zukunft Schule
" in North
2582 Germany. I am responsible for the quality assurance, the customer
2583 relationship management and the communication processes in the
2586 <p
>Since
2001 I constantly have been training myself in communication
2587 and leadership. Besides that I am a forester, a landscaping gardener
2588 and a yoga teacher.
</p
>
2590 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
2591 project?
</strong
></p
>
2593 <p
>I fell in love with Mike ;-).
</p
>
2595 <p
>Very soon after getting to know him I was completely enrolled into
2596 Free Software. At this time Mike did IT-services for one newly
2597 founded school in Kiel. Other schools in Kiel needed concepts for
2598 their IT environment. Often when Mike came home from working at the
2599 newly founded school I found myself listening to his complaints about
2600 several points where the communication with the schools head or the
2601 teachers did not work. So we were clear that he would not work for
2602 one more school if we did not set up a structure for communication
2603 between him, the schools head, the teachers, the students and the
2606 <p
>Together with our friend and hardware supplier Andreas Buchholz we
2607 started to get an overview of free software solutions suitable for
2608 schools. One day before Christmas
2010 Mike and I had a date with Kurt
2609 Gramlich in Gütersloh. As Kurt and I are really interested in building
2610 networks of people and in being in communication we dived into
2611 Skolelinux and brought it to the first grammar schools in Northern

</p

2618 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
2619 Edu?
</strong
></p
>
2621 <p
>First I have to say: I cannot answer this question technically. My
2622 answer comes rather from a social point of view.
</p
>
2624 <p
>The biggest advantage of Skolelinux / Debian Edu I see is the large
2625 and strong international community of Debian Developers in the
2626 background which is very alive and connected over mailinglists, blogs
2627 and meetings. My constant feeling for the Debian Community is: If
2628 something does not work they will somehow fix it. All is well
2629 ;-). This is of course a user experience. What I also get as a big
2630 advantage of Skolelinux / Debian Edu is that everybody who uses it and
2631 works with it can also contribute to it - that includes students,
2632 teachers, parents...
</p
>
2634 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
2635 Edu?
</strong
></p
>
2637 <p
>I will answer this question relating to the internal structure of
2638 Skolelinux / Debian Edu.
</p
>
2640 <p
>What I see as a major disadvantage is that there is a gap between
2641 the group of developers for Debian Edu and the people who make the
2642 marketing, that means the people that bring Skolelinux to the
2643 schools. There is a lack of communication between these two groups and
2644 I think that does not really work for Skolelinux / Debian Edu.
</p
>
2646 <p
>Further I appreciate that Skolelinux / Debian Edu is known as a
2647 do-ocracy. Nevertheless I keep asking myself if at some points a
2648 democracy or some kind of hierarchical project structure would be good
2649 and helpful. I am also missing some kind of contact between the
2650 Skolelinux / Debian Edu communities in Europe or on an international
2651 level. I think it would be good if there was more sharing between the
2652 different countries using Skolelinux / Debian Edu.

2654 <p
><strong
>Which free software do you use daily?
</strong
></p
>
2656 <p
>On my laptop I am still using an Ubuntu
10.04 with a Gnome Desktop
2657 on. As applications I use Openoffice.org, Gedit, Firefox, Pidgin,
2658 LaTeX and GnuCash. For mails I am using Horde. And I am really fond of
2659 my N900 running with Maemo.
</p
>
2661 <p
><strong
>Which strategy do you believe is the right one to use to
2662 get schools to use free software?
</strong
></p
>
2664 <p
>I am really convinced that in our school project
"IT-Zukunft
2665 Schule
" we have developed (and keep developing) a great way to get
2666 schools to use Free Software. We have written a detailed concept for
2667 that so I cannot explain the whole thing here. But in a nutshell the
2668 strategy has three crucial pillars:
</p
>
2672 <li
>We really take time to get what sort of stories, questions and
2673 concerns the schools head and the teachers have about using different
2674 kinds of IT and we take time to enrol them into Free Software.
</li
>
2676 <li
>Our solution for schools is never just technical. In the centre
2677 are always the people who are going to use the software. From the very
2678 beginning of the planning for a school, we tell the schools head that
2679 they are paying us not only for a technical solution for their school,
2680 they also pay us for leading all the communication processes
2681 needed. If they do not want that, we are not working with them because
2682 we cannot give a guarantee for the quality of our work then.
</li
>
2684 <li
>Another focus lies in the training of teachers and students in
2685 co-administrating the IT-System at their school. They start getting in
2686 contact with the Skolelinux / Debian Edu community and they get the
2687 offer to become more and more independent from us.

2710 <p
>I sommer (
2012-
07-
23) hadde Fremover et oppslag om at Narvik
2711 kommune hadde spart mellom
10 og
20 millioner kroner de siste årene på
2712 å bruke Skolelinux på sine skoler. Harstad har også tatt i bruk
2713 Skolelinux på alle sine skoler. Som tidligere Ballangsværing gledet
2714 det meg stort å se at skoleløsningen vi har utviklet siden
2001 tas i
2715 bruk i området der jeg vokste opp, og dermed bidrar til en bedre og
2716 billigere skolehverdag.
</p
>
2718 <p
>Skolelinux er en komplett IT-løsning for elevnettverket på en
2719 skole, med både nettverkstjenester og løsning for elevmaskiner med
2720 pedagogisk programvare, som tillater en å øke levetiden på en
2721 datamaskin i skolen med mange år. En undersøkelse publisert i mars
2722 2012 viste at de
56 norske skolene som har offentliggjort at de bruker
2723 Skolelinux eller annen Linuxutgave hadde
36% større PC-tetthet enn
2724 landsgjennomsnittet, når en ser på tall rapportert til Grunnskolens
2725 Informasjonssystem. I følge Paul Reidar Løsnesløkken, IKT-konsulent i
2726 Nord-Odal, fungerer datamaskiner godt til de er
8 til
10 år gamle.
</p
>
2728 <p
>I høst (
2012-
09-
29) fortalte Fremover hvordan Ballangen kommune har
2729 opparbeidet seg
20 millioner i underskudd og nok havner på Robek-lista
2730 fra nyttår. Kanskje Ballangen også burde ta i bruk Skolelinux for å
2731 spare penger? Hvis kommunen mangler kompetanse lokalt på Linux finnes
2732 det kommersielle selskaper som tilbyr driftstjenester rundt
2733 Skolelinux, og jeg bør vel avsløre at jeg selv er involvert i et av
2734 dem, Skolelinux Drift AS. Kommunen kan dermed få hjelp hvis de ikke
2735 ønsker å bygge opp egen kompetanse.

2808 <p

2809 skrevet om til å akseptere ord med bindestrek (f.eks. «e-post»). Litt
2810 over
10.000 slike ordformer er lagt til i orddatabasen. I tillegg er
2811 det kommet en del nye ord og rettelser rapportert inn av de frivillige
2812 som gjennomfører korrektur av orddatabasen i prosjektet. For å få

>After a long break in my row of interviews with people in the
2903 <a href=
"http://www.skolelinux.org/
">Debian Edu and Skolelinux
</a
>
2904 community, I finally found time to wrap up another. This time it is
2905 Giorgio Pioda, which showed up on the mailing list at the start of
2906 this year, asking questions and inspiring us to improve the first time
2907 administrators experience with Skolelinux. :) The interview was
2908 conduced in May, but I only found time to publish it now.
</p
>
2910 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
2912 <p
>I have a PhD in chemistry but since several years I work as teacher
2913 in secondary (
15-
18 year old students) and tertiary (a kind of
"light
"
2914 university) schools. Five years ago I started to manage a Learning
2915 Management Service server and slowly I got more and more involved with
2916 IT.
3 years ago the graduating schools moved completely to Linux and I
2917 got the head of the IT for this. The experience collected in chemistry
2918 labs computers (for example NMR analysis of protein folding) and in
2919 the IT-courses during university where sufficient to start. Self
2920 training is anyway very important
</p
>
2922 <p
>I live in the Italian speaking part of Switzerland, and the
2923 <a href=
"http://www.spse.ch/
">SPSE school
</a
> (secondary) is a very
2924 special sport school for young people who try to became sport pro (for
2925 all sports, we have dozens of disciplines represented) and we are
2926 recognised by the Olympic Swiss Organisation.
2928 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
2929 project?
</strong
></p
>
2931 <p
>Looking for Linux / Primary Domain Controller (PDC) I found it
2932 already several years ago. But since the system was still not
2933 Kerberized and since our schools relies strongly on laptops I didn
't
2934 use it. I plan to introduce it in the next future, probably for the
2935 next school year, since the squeeze release solved this security
2938 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
2939 Edu?
</strong
></p
>
2941 <p
>Many. First of all there is a strong and living community that is
2942 very generous for help and hints. Chat help is crucial, together with
2943 the mailing list. Second. With Skolelinux you get an already well
2944 engineered platform and you don
't have to start to build up your PDC
2945 and your clients from GNU/scratch; I
've already done this once and I
2946 can tell it, it is hard. Third, since Skolelinux is a standard
2947 platform, it is way easier to educate other IT people and even if the
2948 head IT is sick another one could pick up the task without too much
2951 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
2952 Edu?
</strong
></p
>
2954 <p
>The only real problem I see is that it is a little too less
2955 flexible at client level. Debian stable is rocky and desirable, but
2956 there are many reasons that force for another choice. For example the
2957 need of new drivers for new PC, or the need for a specific OS for some
2958 devices that have specific software packages for another specific
2959 distribution (I have such a case for whiteboards that have only
2960 Ubuntu packages). Thus, I prepared compatibility packages educlient
2961 and eduroaming, hoping not to use them ;-)
</p
>
2963 <p
><strong
>Which free software do you use daily?
</strong
></p
>
2965 <p
>I have a Debian Stable PDC at school (Kerberos, NIS, NFS) with
2966 mixed Debian and Ubuntu clients. If you think that this triad
2967 combination is exotic... well I discovered right yesterday that
2968 <a href=
"http://moo.nac.uci.edu/~hjm/Perceus-Report.html
">Perceus
</a
>
2969 has the same...
</p
>
2971 <p
>For myself I run Debian wheezy/sid, but this combination is good
2972 only I you have enough competence to fix stuff for yourself, if
2973 something breaks. Daily I use texmacs, gnumeric, a little bit of R
2974 statistics, kmplot, and less frequently OpenOffice.org.
</p
>
2976 <p
><strong
>Which strategy do you believe is the right one to use to
2977 get schools to use free software?
</strong
></p
>
2979 <P
>I think that the only real argument that school managers
"hear
" is
2980 cost reduction. They don
't give too much weight on quality, stability,
2981 just because they are normally not open to change.
</p
>
2983 <p
>Students adapts very quickly to GNU/Linux (and for them being able
2984 to switch between different OS is a plus value); teachers and managers
2985 don
't.
</p
>
2987 <p
>We decided to move to Linux because students at our school have own
2988 laptop and we have the responsibility to keep the laptop ready to use;
2989 we were really unsatisfied with Microsoft since every Monday we had
20
2990 machine to fix for viral infections... With Linux this has been
2991 reduced to zero, since people installs almost only from official
2992 repositories. I think that our special needs brought us to Linux.
2993 Those who don
't have such needs will hardly move to Linux.

3007 henvendelser til avisen for å få artikkelen på nett har så langt ikke
3008 vært vellykket.
</p

3010 <p
>Artikkelen med tittelen
"Narvik kommune bruker gratisprogram i
3011 skolen - Har spart millioner
", forteller om hvordan bruken av
3012 Skolelinux er en stor suksess i Narvik siden det ble tatt i bruk i
3013 2004. Her er noen fine sitater:
</p
>
3016 "- Skolelinux har spart kommunen for store pengesummer, millionbeløp,
3017 som de heller kan bruke på andre ting, sier IKT-konsulent Viggo
3021 <p
>Avisen forteller at de har fått tilgang til beregninger som viser
3022 at Narvik kommune har spart noe mellom
10 og
20 millioner kroner de
3023 siste
8 årene på å bruke Skolelinux, og fortsetter:
</p
>
3027 "Regnestykket tar høyde for sparte kostnader til lisenser som medfølger
3028 de alternative operativsystemene, lavere driftskostnader og lengre
3029 levetid på datautstyret. Totalt har Narvikskolen en maskinpark på
3030 1600 maskiner fordelt på de
11 skolene fra Skjomen i sør til Bjerkvik
3035 <p
>Viggo Fedreheim sier dette om hvor noe av gevinsten kommer fra:
</p
>
3038 "- Vi kan gjenbruke gamle maskiner i skolen som er for dårlig andre
3039 steder i kommunen der de ikke bruker Skolelinux. Levetiden på en
3040 datamaskin blir
3-
5 år lenger med Skolelinux. Vi kaller det for
3041 grønn IT, miljøvennlig IT.
"
3044 <p
>Her er det mulighet for flere kommuner å få et godt IT-system på
3045 skolene, hvis de er villige til å forsøke. De som ikke har kompetanse
3046 innomhus kan kjøpe det fra en av de kommersielle leverandørene av

3130 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
3131 project?
</strong
></p
>
3133 I have followed the Skolelinux project for quite some time by
3134 now. Earlier I tested out the K12-LTSP project, which we used for some
3135 time, but I really like the idea of having a distribution aimed to be
3136 a complete solution for schools with necessary tools integrated. When
3137 K12-LTSP abandoned that idea some years ago, I started to look more
3138 seriously into Skolelinux instead.
3140 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
3141 Edu?
</strong
></p
>
3143 The big point of Skolelinux to me is that it is a complete
3144 distribution, ready to install. It has LDAP-support, MS Windows
3145 integration tools and so forth already configured, saving an
3146 administrator a lot of time and headache. We were using another Linux
3147 based thin-client system called Thinlinc, that has served us very
3148 well. But that Skolelinux is based on VNC and LTSP, to me, is better
3149 when it comes to the kind of multimedia used in schools. That is
3150 showing videos from Youtube or educational TV. It is also easier to
3151 mix thin clients with workstations, since the user settings will be the
3152 same. In our VNC-based solution you had to
"beat around the bush
" by
3153 setting up a second, hidden, home-directory for user settings for the
3154 workstations, because they will be different from the ones used on the
3155 thin clients. Skolelinux support for diskless workstations are very
3156 convenient since a school today often need to use a class room
3157 projector showing videos in full screen. That is easily done with a
3158 small integrated media computer running as a diskless workstation. You
3159 have only two installs to update and configure. One for the thin
3160 clients and one for the workstations. Also saving a lot of time. Our
3161 old system was also based on Redhat and CentOS. They are both very
3162 nice distributions, but they are sometimes painfully slow when it
3163 comes to updating multimedia support and multimedia programs (even
3164 such as Gimp), leaving us with a bit
"oldish
" applications. Debian is

>What do you see as the disadvantages of Skolelinux/Debian
3168 Edu?
</strong

3170 <p
>Debian is a bit too quick when it comes to updating. As an example
3171 we use old HP terminals as thinclients, and two times already this
3172 year (
2012) the updates you get from the repositories has stopped
3173 sound from working with them. It
's a kernel/ALSA issue. So you have
3174 to be more careful properly testing the updates before you run them in
3175 a production environment. This has never happened with CentOS.
</p
>
3177 <p
>I also would like to be able to set my own domain-settings at
3178 install time. In Skolelinux they are kind of hard coded into the
3179 distribution, when it comes to LDAP and at least samba integration.
3180 That is more a cosmetic/translation issue, and not a real problem.
3181 Running MS Windows applications within the Skolelinux environment needs
3182 to be better supported. That is, running them seamlessly via RDP, and
3183 support for single-sign on. That will make the transition to free
3184 software easier, because you can keep the applications you really
3185 need. No support will make it impossible if you work in a school where
3186 some applications can
't be open source. As for us we really need to
3187 run Adobe InDesign in our journalist classes. We run a journalist
3188 education, and is one of the very few non university ones that is ok:d
3189 by Svenska journalistförbundet (Swedish journalist association). Our
3190 education gives the pupils the right of membership there, once they
3191 are done. This is important if you want to get a job.
</p
>
3193 <p
>Adobe InDesign is the program most commonly used in newspapers and
3194 magazines. We used Quark Express before, but they seem to loose there
3195 market to Adobe. The only
"equivalent
" to InDesign in the opensource
3196 world is Scribus, and its not advanced enough. At least not according
3197 to the teacher. I think it would be possible to use it, because they
3198 are not supposed to learn a program, they are supposed to learn how to
3199 edit and compile a newspaper. But politically at our school we are not
3200 there yet. And Scribus lacks a lot of things you find i InDesign.
</p
>
3202 <p
>We used even a windows program for sound editing when it comes to
3203 the radio-journalist part. The year to come we are going to try
3204 Audacity. That software has the same kind of limitations compared to
3205 Adobe Audition, but that teacher is a bit more open minded. We have
3206 tried Ardour also, but that instead is more like a music studio
3207 program, not intended for the kind of editing taking place in a radio
3208 studio. Its way to complex and the GUI is to scattered when you only
3209 want to cut, make pass-overs, add extra channels and normalise. Those
3210 things you can do in Audacity, but its not as easy as in Audition. You
3211 have to do more things manually with envelopes, and that is a bit old
3212 fashion and timewasting. Its also harder to cut and move sound from
3213 one channel to another, which is a thing that you do frequently
3214 because you often find yourself needing to rearrange parts of the
3215 sound file.
</p
>
3217 <p
>So, I am not sure we will succeed in replacing even Audition, but we
3218 will try. The problem is the students have certain expectations when
3219 they start an education towards a profession. So the programs has to
3220 look and feel professional. Good thing with radio, there are many
3221 programs out there, that radio studios use, so its not as standardised
3222 as Newspaper editing. That means, it does not really matter what
3223 program they learn, because once they start working they still have to
3224 learn the program the studio uses, so instead focus has to be to learn
3225 the editing part without to much focus on a specific software.

3229 <p

3230 only open source software, and preferably Linux based. When it comes
3231 to most used applications its OpenOffice, and Firefox (of course ;)

><strong
>Which strategy do you believe is the right one to use to
3235 get schools to use free software?
</strong

>
3237 <p
>To get schools to use free software there has to be good open
3238 source software that are windows based, to ease the transition. But
3239 it
's also very important that the multimedia support is working
3240 flawlessly. The problems with Youtube, Twitter, Facebook and whatever
3241 will create problems when it comes to both teachers and
3242 students. Economy are also important for schools, so using thin
3243 clients, as long as they have good multimedia support, is a very good
3244 idea. It
's also important that the open source software works even for
3245 the administration. It
's hard to convince the teachers to stick with
3246 open source, if the principal has to run Windows. It also creates a
3247 problem if some classes has to use Windows for there tasks, since that
3248 will create a difference in
"status
" between classes, so a good
3249 support for running windows applications via the thin client (Linux)
3250 desktop is essential. At least at our school, where we have mixed
3251 level of educations, from high-school to journalist-school.

2000, der jeg måtte ha
"noe
3497 å gjøre
" under hjemturen over Atlanteren. Jeg kjøpte et par bøker om
3498 Linux i en bokhandel i New York og ble veldig fascinert. Etter
3499 hjemkomsten begynte jeg å jobbe på Ulsrud VGS, som naturfagslærer, men
3500 som IT-interessert ble jeg fort en del av den nye IT-satsningen som
3501 skulle løfte Ulsrud og gi skolen en bedre rykte. Vi hadde ganske
3502 mange maskiner, som gikk på Win98 og to servere som ble oppgradert til
3503 Win2000. Systemene var ustabil og dårlige. På leting etter noe
3504 bedre, uten å knekke ryggen økonomisk, kom jeg over
"Linux i Skolen
"
3505 og Skolelinux. Jeg tok kontakt med miljøet og en gjeng møtte opp på
3506 skolen, der vi gjorde en liten testinstallasjon. Etter et par år var
3507 ryggraden på skolen Linux (Skolelinux) og vi hadde flere hundre
3508 maskiner, både tynne klienter (gamle og nye), bærbare (Debian) og noen
3509 stasjonære (Win2000). På et tidspunkt var Ulsrud den råeste IT-skolen
3510 og det irriterte skolesjefen i Oslo, da de satset hardt på

3515 <p
>Det som gjorde at vi fikk inn Skolelinux var ene og alene
3516 økonomiske. Det faktum at vi slapp å kjøpe masse nye lisenser og at
3517 vi kunne bruke gammel hardware. Alt i alt gjorde dette at vi sparte
3518 mye, men i stede for å bruke mindre på IT brukte vi det vi sparte på å
3519 skaffe mer hardware og på den måten gi det beste tilbudet i landet til
3520 våre elever. For oss som driftet var det himmel å ha et system som
3521 gikk å administrere sentralt og effektivt. Det var heller ikke så
3522 dumt at vi kunne
"låse
" maskinene mer effektivt enn vi kunne med
3523 Microsoft Windows, slik at vi slapp mye feil og problemer som ble
3524 forårsaket av
"kreative
" elever.

3529 Husker ikke alle, men det var et knippe med pedagogiske programmer de
3530 ikke fikk. I dag tror jeg det problemet er langt mindre da det meste
3531 av disse kjøres gjennom nettleseren.

3537 Firefox brukes mest av disse. På Apple-serveren hjemme bruker jeg
3538 HandBrake mye, og jeg har installert OpenWRT på flere av
3539 basestasjonene både hjemme og på jobben. I tillegg til det har jeg i
3540 flere år finansiert et prosjekt som heter
3541 <a href=

3542 vi lager et rammeverk for søk, der alt vi bruker fri programvare. Det

3546 skoler til å ta i bruk fri programvare?

3548 <p
>Når det gjelder IT og skole er fortsatt økonomi veldig viktig. Så
3549 man må oppfylle minimumskravene (ikke være best, men bra nok) og selge
3550 seg inn på hvor mye man sparer. Det betyr selvsagt at man sparer på
3551 lisenser, men også på driftsinnsats. Men nå når jeg ikke er en aktiv
3552 del av miljøet lenger hører jeg nesten ingen ting om fri programvare.
3553 Jeg stiller meg da spørsmålet om det har blitt stille rundt miljøet,
3554 eller om jeg kun så det tydeligere før når jeg var aktiv? Uansett er
3555 det for stille rundt Skolelinux-prosjektet nå.

3567 This time we get to know José Luis Redrejo Rodríguez, one of our great
3568 helpers from Spain. His effort was the reason we added support for
3569 several desktop types (KDE, Gnome and most recently LXDE) in Debian
3570 Edu, and have all of these available in the recently published

3615 <p

3618 laptops, netbooks, tablets, interactive white-boards, etc.
</p

3620 <p

3621 not use the same solutions for primary schools and secondary or even

3624 <p
>But, looking at these differences, and looking back to the things
3625 we
've done and implemented, and the places were we have spent most of
3626 our forces, I think we should focus as much as possible in free
3627 multi-platform environments, using only standards tools, and moving
3628 more and more to Internet or network solutions that could be deployed
3629 using wireless. I think we
'll see more and more personal devices in
3630 the schools, devices the students and teachers will take home with
3631 them, so the solutions must be able to be taken at home and continue
3632 working there.

"http://www.debian.org/News/

20120311.nb.html
">Debian Edu
3643 based on Squeeze
</a
>, I came across some issues that should be
3644 addressed in the Wheezy release. I finally found time to wrap up my
3645 notes and provide quick summary of what I found, with a bit
3646 explanation.
</p
>
3650 <li
>We need to rewrite our package installation framework, as tasksel
3651 changed from using tasksel tasks to using meta packages (aka packages
3652 with dependencies like our education-* packages), and our installation
3653 system depend on tasksel tasks in
3654 /usr/share/tasksel/debian-edu-tasks.desc for package
3655 installation.
</li
>
3657 <li
>Enable Kerberos login for more services. Now with the Kerberos
3658 foundation in place, we should use it to get single sign on with more
3659 services, and avoiding unneeded password / login questions. We should
3660 at least try to enable it for these services:
3663 <li
>CUPS for admins to add/configure printers and users when using
3665 <li
>Nagios for admins checking the system status.
</li
>
3666 <li
>GOsa for admins updating LDAP and users changing their passwords.
</li
>
3667 <li
>LDAP for admins updating LDAP.
</li
>
3668 <li
>Squid for users when exam mode / filtering is active.
</li
>
3669 <li
>ssh for admins and users to save a password prompt.
</li
>
3671 </ul
></li
>
3673 <li
>When we move GOsa to use Kerberos instead of LDAP bind to
3674 authenticate users, we should try to block or at least limit access to
3675 use LDAP bind for authentication, to ensure Kerberos is used when it
3676 is intended, and nothing fall back to using the less safe LDAP bind
</li
>
3678 <li
>Merge debian-edu-config and debian-edu-install. The split made
3679 sense when d-e-install did a lot more, but these days it is just an
3680 inconvenience when we update the debconf preseeding values.
</li
>
3682 <li
>Fix partman-auto to allow us to abort the installation before
3683 touching the disk if the disk is too small. This is
3684 <a href=
"http://bugs.debian.org/
653305">BTS report #
653305</a
> and the
3685 d-i developers are fine with the patch and someone just need to apply
3686 it and upload. After this is done we need to adjust
3687 debian-edu-install to use this new hook.
</li
>
3689 <li
>Adjust to new LTSP framework (boot time config instead of install
3690 time config). LTSP changed its design, and our hooks to install
3691 packages and update the configuration is most likely not going to work
3694 <li
>Consider switching to NBD instead of NFS for LTSP root, to allow
3695 the Kernel to cache files in its normal file cache, possibly speeding
3696 up KDE login on slow networks.
</li
>
3698 <li
>Make it possible to create expired user passwords that need to
3699 change on first login. This is useful when handing out password on
3700 paper, to make sure only the user know the password. This require
3701 fixes to the PAM handling of kdm and gdm.
</li
>
3703 <li
>Make GUI for adding new machines automatically from sitesummary.
3704 The current command line script is not very friendly to people most
3705 familiar with GUIs. This should probably be integrated into GOsa to
3706 have it available where the admin will be looking for it..
</li
>
3708 <li
>We should find way for Nagios to check that the DHCP service
3709 actually is working (as in handling out IP addresses). None of the
3710 Nagios checks I have found so far have been working for me.
</li
>
3712 <li
>We should switch from libpam-nss-ldapd to sssd for all profiles
3713 using LDAP, and not only on for roaming workstations, to have less
3714 packages to configure and consistent setup across all profiles.
</li
>
3716 <li
>We should configure Kerberos to update LDAP and Samba password
3717 when changing password using the Kerberos protocol. The hook was
3718 requested in
<a href=
"http://bugs.debian.org/
588968">BTS report
3719 #
588968</a
> and is now available in Wheezy. We might need to write a
3720 MIT Kerberos plugin in C to get this.
</li
>
3722 <li
>We should clean up the set of applications installed by default.
3725 <li
>reduce the number of chemistry visualisers
</li
>
3726 <li
>consider dropping xpaint
</li
>
3727 <li
>and probably more?
</li
>
3728 </ul
></li
>
3730 <li
>Some hardware need external firmware to work properly. This is
3731 mostly the case for WiFi network cards, but there are some other
3732 examples too. For popular laptops to work out of the box, such
3733 firmware need to be installed from non-free, and we should provide
3734 some GUI to do this. Ubuntu already have this implemented, and we
3735 could consider using their packages. At the moment we have some
3736 command line script to do this (one for the running system, another
3737 for the LTSP chroot).
</li
>
3740 <li
>In Squeeze, we provide KDE, Gnome and LXDE as desktop options. We
3741 should extend the list to Xfce and Sugar, and preferably find a way to
3742 install several and allow the admin or the user to select which one to
3745 <li
>The golearn tool from the goplay package make it easy to check out
3746 interesting educational packages. We should work on the package
3747 tagging in Debian to ensure it represent all the useful educational
3748 packages, and extend the tool to allow it to use packagekit to install
3749 new applications with a simple mouse click.
</li
>
3751 <li
>The Squeeze version got half a exam solution already in place,
3752 with the introduction of iptable based network blocking, but for it to
3753 be a complete exam solution the Squid proxy need to enable
3754 filtering/blocking as well when the exam mode is enabled. We should
3755 implement a way to easily enable this for the schools that want it,
3756 instead of the
"it is documented
" method of today.
</li
>
3758 <li
>A feature used in several schools is the ability for a teacher to
3759 "take over
" the desktop of individual or all computers in the room.
3760 There are at least three implementations,
3761 <a href=
"italc.sourceforge.net/
">italc
</a
>,
3762 <a href=
"http://www.itais.net/help/en/
">controlaula
</a
> og
3763 <a href=
"http://www.epoptes.org/
">epoptes
</a
> and we should pick one of
3764 them and make it trivial to set it up in a school. The challenges is
3765 how to distribute crypto keys and how to group computers in one room
3766 and how to set up which machine/user can control the machines in a
3767 given room.
</li
>
3769 <li
>Tablets and surf boards are getting more and more popular, and we
3770 should look into providing a good solution for integrating these into
3771 the Debian Edu network. Not quite sure how. Perhaps we should
3772 provide a installation profile with better touch screen support for
3773 them, or add some sync services to allow them to exchange
3774 configuration and data with the central server. This should be
3775 investigated.

2010, Mike Gabriel showed up on the

3796 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
3798 <p
>My name is Mike Gabriel, I am
38 years old and live near Kiel,
3799 Schleswig-Holstein, Germany. I live together with a wonderful partner
3800 (Angela Fuß) and two own children and two bonus children (contributed
3801 by Angela).
</p
>
3803 <p
>During the day I am part-time employed as a system administrator
3804 and part-time working as an IT consultant. The consultancy work
3805 touches free software topics wherever and whenever possible. During
3806 the nights I am a free software developer. In the gaps I also train in
3807 becoming an osteopath.
</p
>
3809 <p
>Starting in
2010 we (Andreas Buchholz, Angela Fuß, Mike Gabriel)
3810 have set up a free software project in the area of Kiel that aims at
3811 introducing free software into schools. The project
's name is
3812 "IT-Zukunft Schule
" (IT future for schools). The project links IT
3813 skills with communication skills.
</p
>
3815 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
3816 project?
</strong
></p
>
3818 <p
>While preparing our own customised Linux distribution for
3819 "IT-Zukunft Schule
" we were repeatedly asked if we really wanted to
3820 reinvent the wheel. What schools really need is already available,
3821 people said. From this impulse we started evaluating other Linux
3822 distributions that target being used for school networks.
</p
>
3824 <p
>At the end we short-listed two approaches and compared them: a
3825 commercial Linux distribution developed by a company in Bremen,
3826 Germany, and Skolelinux / Debian Edu. Between
12/
2010 and
03/
2011 we
3827 went to several events and met people being responsible for marketing
3828 and development of either of the distributions. Skolelinux / Debian
3829 Edu was by far much more convincing compared to the other product that
3830 got short-listed beforehand--across the full spectrum. What was most
3831 attractive for me personally: the perspective of collaboration within
3832 the developmental branch of the Debian Edu project itself.
</p
>
3834 <p
>In parallel with this, we talked to many local and not-so-local
3835 people. People teaching at schools, headmasters, politicians, data
3836 protection experts, other IT professionals.
</p
>
3838 <p
>We came to two conclusions:
</p
>
3840 <p
>First, a technical conclusion: What schools need is available in
3841 bits and pieces here and there, and none of the solutions really fit
3842 by
100%. Any school we have seen has a very individual IT setup
3843 whereas most of each school
's requirements could mapped by a standard
3844 IT solution. The requirement to this IT solution is flexibility and
3845 customisability, so that individual adaptations here and there are
3846 possible. In terms of re-distributing and rolling out such a
3847 standardised IT system for schools (a system that is still to some
3848 degree customisable) there is still a lot of work to do here
3849 locally. Debian Edu / Skolelinux has been our choice as the starting
3852 <p
>Second, a holistic conclusion: What schools need does not exist at
3853 all (or we missed it so far). There are several technical solutions
3854 for handling IT at schools that tend to make a good impression. What
3855 has been missing completely here in Germany, though, is the enrolment
3856 of people into using IT and teaching with IT.
"IT-Zukunft Schule
"
3857 tries to provide an approach for this.
</p
>
3859 <p
>Only some schools have some sort of a media concept which explains,
3860 defines and gives guidance on how to use IT in class. Most schools in
3861 Northern Germany do not have an IT service provider, the school
's IT
3862 equipment is managed by one or (if the school is lucky) two (admin)
3863 teachers, most of the workload these admin teachers get done in there
3864 spare time.
</p
>
3866 <p
>We were surprised that only a very few admin teachers were
3867 networked with colleagues from other schools. Basically, every school
3868 here around has its individual approach of providing IT equipment to
3869 teachers and students and the exchange of ideas has been quasi
3870 non-existent until
2010/
2011.
</p
>
3872 <p
>Quite some (non-admin) teachers try to avoid using IT technology in
3873 class as a learning medium completely. Several reasons for this
3874 avoidance do exist.
</p
>
3876 <p
>We discovered that no-one has ever taken a closer look at this
3877 social part of IT management in schools, so far. On our quest journey
3878 for a technical IT solution for schools, we discussed this issue with
3879 several teachers, headmasters, politicians, other IT professionals and
3880 they all confirmed: a holistic approach of considering IT management
3881 at schools, an approach that includes the people in place, will be new
3882 and probably a gain for all.
</p
>
3884 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
3885 Edu?
</strong
></p
>
3887 <p
>There is a list of advantages: international context, openness to
3888 any kind of contributions, do-ocracy policy, the closeness to Debian,
3889 the different installation scenarios possible (from stand-alone
3890 workstation to complex multi-server sites), the transparency within
3891 project communication, honest communication within the group of
3892 developers, etc.

3897 <p

</p
>
3899 <p
>Technically:
<a href=
"http://bugs.debian.org/
311188">BTS issue
3900 #
311188</a
>, tricky upgradability of a Debian Edu main server, network
3901 client installations on top of a plain vanilla Debian installation
3902 should become possible sometime in the near future, one could think
3903 about splitting the very complex package debian-edu-config into
3904 several portions (to make it easier for new developers to
3905 contribute).
</p
>
3907 <p
>Another issue I see is that we (as Debian Edu developers) should
3908 find out more about the network of people who do the marketing for
3909 Debian Edu / Skolelinux. There is a very active group in Germany
3910 promoting Skolelinux on the bigger Linux Days within Germany. Are
3911 there other groups like that in other countries? How can we bring
3912 these marketing people together (marketing group A with group B and
3913 all of them with the group of Debian Edu developers)? During the last
3914 meeting of the German Skolelinux group, I got the impression of people
3915 there being rather disconnected from the development department of
3916 Debian Edu / Skolelinux.

3929 is being integrated in Ubuntu

7 years, Skolelinux is part of our schools infrastructure, namely
3985 our main server (tjener), one LTSP (today without thin clients), and
3986 approximately
50 work stations. Most of these have the option to boot a
3987 locally installed Skolelinux image. As a consequence, I joined quite
3988 a few events dealing with free software or Linux, and met many Debian

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

4007 <p
>While Debian
's stability has loads of advantages for servers, this
4008 might be different in some cases for clients: Schools with unlimited
4009 budget might buy new hardware with components that are not yet
4010 supported by Debian stable, or wish to use more recent versions of
4011 office packages or desktop environments. These schools have the
4012 option to run Debian testing or other distributions - if they have the
4013 capacity to do so. Another issue is that Debian release cycles
4014 include a wide range of changes; therefor a high percentage of human
4015 power seems to be absorbed by just keeping the features of Skolelinux
4016 within the new setting of the version to come. During this process,
4017 the cogs of Debian Edu are getting more and more professional,
4018 i.e. harder to understand for novices.

4036 <li
>Make budget baskets corresponding: In Germany
's public schools
4037 there are more or less fixed budgets for IT equipment (including
4038 licenses), so schools won
't benefit from any savings here. This
4039 privilege is left to private schools which have consequently a large
4040 share among German Skolelinux schools.

4042 <li
>Get free software in the seminars where would-be teachers are
4043 trained. In many cases, teachers
' software customs are respected by
4044 decision makers rather than the expertise of any IT experts.
</li
>
4046 <li
>Don
't limit ourself to free software run natively. Everybody uses
4047 free software or free licenses (for instance Wikipedia), and this
4048 general concept should get expanded to free educational content to be
4049 shared world wide (school books e.g.).
</li

4051 <li
>Make clear where ever you can that the market share of free (libre)
4052 office suites is much above
20 p.c. today, and that you pupils don
't
4053 need to know the

4057 <li
>Spread free software, or even collections of portable free apps

4077 intervjurunde av folkene bak Skolelinux-løsningen. Jeg har kjent Alf
4078 Tonny siden vi møttes som barn på påskefjellet i Ofoten, og ble
4079 gledelig overrasket da han dukket opp i Skolelinux-prosjektet etter å
4080 ikke ha sett noe til ham på mange år.

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

4084 <p
>Jeg er utdannet kokk av yrke, og har utøvet yrket i
12 år. Men
4085 etter at ryggen sa takk før seg, studerte jeg nettverksadministrasjon
4086 ved Næringsakademiet i Bergen årene
2008-
2009 slik at jeg kunne
4087 forfølge en av mine største interesser - data. Til daglig jobber jeg
4088 ved
<a href=
"http://www.narvikskolen.no/parken/
">Parken
4089 ungdomsskole
</a
> med å drifte skolens PC-er. Har også litt
4090 musikkundervisning.
</p
>
4092 <p
>Mitt mål er å bevisstgjøre musikklærene mulighetene med de frie
4093 programmene som finnes i Skolelinux, blant annet Rosegarden.
</p
>
4095 <p
>Har i mange år drevet med musikk og en av grunnen til at Rosegarden
4096 falt i smak for min del, var fordi denne fungere og ligner mest på
4097 Windows-programmet (cubase) jeg jobbet mye med da jeg i mine yngre
4098 dager var «Windows fanatiker». Ble introdusert til Linux av en kompis
4099 av meg for omtrent
14 år siden, og har bare blitt mer og mer glad i
4100 dette operativsystemet.
</p
>
4102 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
4104 <p
>Da jeg ble sykemeldt fra min gamle jobb, og måtte omskoleres,
4105 havnet jeg i
2007 sammen med Viggo Fedreheim på IKT-avdelingen i
4106 Narvik kommune, der ble jeg for første gang introdusert til
4107 Skolelinuxprosjektet.
</p
>
4109 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
4111 <p
>Skolelinux er enkelt å holde i drift og masse flotte programmer som
4112 geogebra, ktouch og kgeografi følger med pakken. Man kan ta i bruk
4113 gamle PC-er igjen, slik at skoler med dårlig råd får opp en brukbar
4114 PC-park. PC-er som er ca
6-
9 år gamle fungere tilfredstillende, bare
4115 de har
512 MB RAM eller mer.
</p
>
4117 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
4119 <p
>Ulempene er at noen av de pedagogiske programmene som lærene ønsker
4120 å bruke fungere dårlig med Linux. Mye pga. av at disse programmene
4121 blir ikke laget til Linuxbaserte operativsystemer.
</p
>
4123 <p
>Video- og bilde-redigering har dessverre en del mangler, mange av
4124 programmene har en tendens til og krasje. Det gjelder blant annet
4125 <a href=
"http://www.kdenlive.org/
">kdenlive
</a
> og
4126 <a href=
"http://www.openshotvideo.com/
">openshot
</a
>, for å nevne
4127 noen. De er ikke stabile nok. Når elevene kommer med filmsnutter de
4128 ønsker og jobbe med, så godtar ikke programmene filene, og når elevene
4129 jobber med redigering bare krasjer programmene uten forvarsel. Det er
4130 for vanskelig å få noe som bare fungerer ut av boksen her. Når en elev
4131 plugger inn et videokamera eller fotoapparat så er det alltid noe som
4132 ikke vil fungere. Programmene godtar ikke format, godtar ikke
4133 kameraet, osv., osv. Det er dessverre med på og dra ned en positiv
4134 opplevelse av bruk av fri programvare.
</p
>
4136 <p
>Man må ofte bruke flere en et video redigerings program før og få
4137 fullført en ønsket oppgave.
</p
>
4139 <p
>Eksempel:
</p
>
4141 <p
>Hvis det ene programmet ikke vil ta i mot videofilen klarer et
4142 annet det, men det programmet som klarer det kan ikke gjøre de samme
4143 oppgavene som det programmet som ikke ville ta i mot filen,
4144 Tilsvarende er det med foto, man må bruke flere programmer for å få
4145 et ferdig resultat. Til dags dato har jeg enda ikke funnet et video-
4146 og fotoprogram som kan tilfredstillende fullføre en oppgave.
</p
>
4148 <p
>Så man kan klare og fullføre en oppgave, men i verste fall må man
4149 innom
3-
4 programmer for å få det til. Så jeg har enda ikke til dags
4150 dato sett at et program fungere
100% til alt.
</p
>
4152 <p
>Det programmet jeg har best erfaring til er
4153 <a href=
"http://cinelerra.org/
">cinelerra
</a
>, men dessverre har det
4154 også tendenser og krasje av og til uten grunn.
</p
>
4156 Lydsystemet kan også være et mareritt. Konkret snakker jeg om når du
4157 bruker for eksempel et smartboard, så følger det med USB-lydkort på
4158 disse. Problemet ligger her i at systemet ikke vil velge rett
4159 lydkort, så man må inn med padevchooser for å sette opp PulseAudio
4160 til og velge at USB-lydkortet skal brukes. Det blir for tungvindt for
4161 lærene, de ønsker at ting skal fungere med en gang. (min løsning på
4162 det problemet ble at jeg måtte deaktivere lydkortet som fantes på
4163 maskinen) men da må man bestandig slå på smartboard-tavla.
4165 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
4167 Programmene jeg bruker mest av er: Rosegarden, jack, qsynth, audacity,
4168 k3b, openttd og libreoffice.
4170 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
4171 skoler til å ta i bruk fri programvare?
</strong
></p
>
4173 Jeg tror det må bevisstgjøring av Skolene til, dvs. reklamere høylytt
4174 og fortelle og vise de andre skolene at frie programvarer faktisk
4175 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
4186 publish another interview with the people behind
4187 <a href=
"http://www.skolelinux.org/
">Debian Edu and Skolelinux
</a
>.
4188 This time it is one of our German developers, who have helped out over the
4189 years to make sure both a lot of major but also a lot of the minor
4190 details get right before release.
4192 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
4194 <p
>My name is Jürgen Leibner, I
'm
49 years old and living in
4195 Bielefeld, a town in northern Germany. I worked nearly
20 years as
4196 certified engineer in the department for plant design and layout of an
4197 international company for machinery and equipment. Since
2011 I
'm a
4198 certified technical writer (tekom e.V.) and doing technical
4199 documentations for a steam turbine manufacturer. From April this year
4200 I will manage the department of technical documentation at a
4201 manufacturer of automation and assembly line engineering.
</p
>
4203 <p
>My first contact with linux was around
1993. Since that time I used
4204 it at work and at home repeatedly but not exclusively as I do now at
4205 home since
2006.
</p
>
4207 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4208 project?
</strong
></p
>
4210 <p
>Once a day in the early year of
2001 when I wanted to fetch my
4211 daughter from primary school, there was a teacher sitting in the
4212 middle of
20 old computers trying to boot them and he failed. I helped
4213 him to get them booting. That was seen by the school director and she
4214 asked me if I would like to manage that the school gets all that old
4215 computers in use. I answered:
"Yes
".
</p
>
4217 <p
>Some weeks later every of the
10 classrooms had one computer
4218 running Windows98. I began to collect old computers and equipment as
4219 gifts and installed the first computer room with a peer-to-peer
4220 network. I did my work at school without being payed in my spare time
4221 and with a lot of fun. About one year later the school was connected
4222 to Internet and a local area network was installed in the school
4223 building. That was the time to have a server and I knew it must be a
4224 Linux server to be able to fulfil all the wishes of the teachers and
4225 being able to do this in a transparent and economic way, without extra
4226 costs for things like licence and software. So I searched for a
4227 school server system running under Linux and I found a couple of
4228 people nearby who founded
'skolelinux.de
'. It was the Skolelinux
4229 prerelease
32 I first tried out for being used at the school. I
4230 managed the IT of that school until the municipal authority took over
4231 the IT management and centralised the services for all schools in
4232 Bielefeld in December of
2006.

4234 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4235 Edu?
</strong
></p
>
4237 <p
>When I
'm looking back to the beginning, there were other advantages
4238 for me as today.
</p
>
4240 <p
>In the past there were advantages like:
</p
>
4244 <li
>I don
't need to buy it so it generates no costs to the school as
4245 they had little money to spent for computers and software.
</li
>
4247 <li
>It has a licence which grands all rights to use it without
4250 <li
>It was more able to fit all requirements of a server system for
4251 schools than a Microsoft server system, even if there are only Windows
4252 clients because of it
's preconfigured overall concept of being a
4253 infrastructure solution and community for schools, not only a
4256 <li
>I was able to configure the server to the needs of the
4259 </ul
></p
>
4261 <p
>Today some of the advantages has been lost, changed or new ones
4262 came up in this way:
</p
>
4266 <li
>Most schools here do have money to buy hardware and software
4269 <li
>They are today mostly managed from central IT departments which
4270 have own concepts which often do not fit to Debian Edu concepts
4271 because they are to close to Microsoft ideology.
</li
>
4273 <li
>With the Squeeze version of Debian Edu which now uses GOsa² for
4274 management I feel more able to manage the daily tasks than with the
4275 interfaces used in the past.
</li
>
4277 <li
>It is more modular than in the past and fits even better to the
4278 different needs.
</li
>
4280 <li
>The documentation is usable and gets better every day.
</li
>
4282 <li
>More people than ever before are using Debian Edu all over the
4283 world and so the community, which is an very important part I think,
4284 is sharing knowledge and minds.
</li
>
4286 <li
>Most, maybe all, of the technical requirements for schools are
4287 solved today by Debian Edu.

4291 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
4292 Edu?
</strong

>
4296 <li
>There are too few IT companies able to integrate Debian Edu into
4297 their product portfolio for serving schools with concepts or even
4298 whole municipality areas.
</li

4300 <li
>Debian Edu has beside other free and open software projects not
4301 enough lobbyists which promote free and open software to
4302 politicians.

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

>
4310 <p
>I use Debian stable on my home server and on my little desktop
4311 computer. On my laptop I use Debian testing/sid. The applications I
4312 use on my laptop and my desktop are Open/Libre-office, Iceweasel,
4313 KMail, DigiKam, Amarok, Dolphin, okular and all the other programs I
4314 need from the KDE environment. On console I use newsbeuter, mutt,
4315 screen, irssi and all the other famous and useful tools.
</p
>
4317 <p
>My home server provides mail services with exim, dovecot, roundcube
4318 and mutt over ssh on the console, file services with samba, NFS,
4319 rsync, web services with apache, moinmoin-wiki, multimedia services
4320 with gallery2 and mediatomb and database services with MySQL for me
4321 and the whole family. I probably forgot something.

>Da jeg googlet etter noe annet kom jeg tilfeldigvis over
4338 <a href=
"http://www.duo.uio.no/sok/work.html?WORKID=
58309">en
4339 hovedfagsoppgave
</a
> ved Universitetet i Oslo som diskuterer verdien
4340 av GPLs fire friheter for brukerne av IT-systemer. Jeg ble fascinert
4341 over det som presenteres der. Her er sammendraget:
</p
>
4343 <p
><blockquote
>
4345 <p
>Motivasjonen til å skrive denne oppgaven er en personlig undring
4346 over hvorfor det primært, og ofte eksklusivt, fokuseres på det
4347 økonomiske aspektet ved utredninger om fri programvare er et godt valg
4348 for det offentlige. Fri og produsenteid programvare bygger på
4349 fundamentalt forskjellige ideologier som kan ha implikasjoner utover
4350 økonomiske kostnader. Kunnskapskulturen som er med på å definere fri
4351 programvare er basert på åpenhet, og er en verdi i seg selv.
</p
>
4353 <p
>Oppgavens tema er programvarelisensen GPL og frihet. GPL-lisensiert
4354 programvare gir visse friheter i forhold til produsenteid
4355 programvare. Mitt spørsmål er om, og eventuelt i hvilken utstrekning,
4356 disse frihetene blir benyttet av ulike brukere og hvordan de
4357 manifesterer seg for disse brukerne. Sentrale spørsmål i oppgaven
4361 <li
>Hvordan fordeles handlekraft gjennom lisensieringen av programvaren?
</li
>
4362 <li
>Hvilke konsekvenser har programvarelisensen for de ulike brukere?
</li
>
4365 <p
>Fri programvare gir blant annet brukeren mulighet til å studere og
4366 modifisere kildekoden. Denne formen for frihet erverves gjennom
4367 kunnskap og krever at brukeren også er en ekspert. Hva skjer med
4368 frihetene til GPL når sluttbrukeren er en annen? Dette diskuteres i
4369 dialog med informantene.
</p
>
4371 <p
>Jeg har i denne oppgaven samlet inn intervjudata fra IKT-ansvarlige
4372 ved grunnskolene i Nittedal kommune, driftsansvarlig og IKT-veilederen
4373 for skolene i kommunen, samt IKT-koordinator for utdanning i Akershus
4374 fylkeskommune og bokmåloversettere av OpenOffice.org. Den empiriske
4375 delen av oppgaven er delt inn i to seksjoner; den første omhandler
4376 operativsystemet Skolelinux, den andre kontorprogrampakken
4377 OpenOffice.org.
</p
>
4379 <p
>Som vi vil se gir GPL lokal frihet og kontroll gjennom omfordeling
4380 av makt fra produsent til bruker. Brukerens makt analyseres gjennom
4381 begrepene brukermedvirkning og handlingsfrihet. Det blir også lagt
4382 vekt på strukturelle forhold rundt bruken av teknologi, og spesielt de
4383 økonomiske begrepene nettverkseksternaliteter, innlåsing og
4384 stiavhengighet. Dette er begreper av spesiell nytte når objektet som
4385 omsettes eller distribueres er et kommunikasjonsprodukt, fordi verdien
4386 til et slikt gode for en potensiell bruker avhenger av antall
4387 eksisterende brukere av godet. I tilknytning til denne problematikken
4388 inneholder oppgaven også en diskusjon rundt åpne standarder og
4391 <p
>Oppgaven konkluderer med at de «fire frihetene» som GPL-lisensen er
4392 laget for å beskytte er av avgjørende betydning for bruken av
4393 OpenOffice.org og Skolelinux, i Akershus fylkeskommune såvel som i
4394 skolene i Nittedal. Distribusjonen av handlekraft er ikke helt
4395 symmetrisk. Det er først og fremst de profesjonelle utviklerne i
4396 Skolelinux som direkte kan nyttiggjøre seg friheten til å endre kode,
4397 mens en sluttbruker som Nittedal kommune nyttiggjør seg den økonomiske
4398 friheten til å kunne distribuere programmene. Det er imidlertid også
4399 slik at ingen aktør klarer seg uten alle disse «frihetene».

4419 years. He was also a key contributor in getting GOsa and Kerberos set

4426 <p
>My name is Andreas Mundt, I grew up in south Germany. After
4427 studying Physics I spent several years at university doing research in
4428 Quantum Optics. After that I worked some years in an optics company.
4429 Finally I decided to turn over a new leaf in my life and started
4430 teaching
10 to
19 years old kids at school. I teach math, physics,
4431 information technology and science/technology.
</p

4433 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4434 project?
</strong
></p
>
4436 <p
>Already before I switched to teaching, I followed the Debian Edu
4437 project because of my interest in education and Debian. Within the
4438 qualification/training period for the teaching, I started
4439 contributing.
</p

4441 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4442 Edu?
</strong
></p
>
4444 <p
>The advantages of Debian Edu are the well known name, the
4445 out-of-the-box philosophy and of course the great free software of the
4446 Debian Project!
</p
>
4448 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
4449 Edu?
</strong
></p
>
4451 <p
>As every coin has two sides, the out-of-the-box philosophy has its
4452 downside, too. In my opinion, it is hard to modify and tweak the
4453 setup, if you need or want that. Further more, it is not easily
4454 possible to upgrade the system to a new release. It takes much too
4455 long after a Debian release to prepare the -Edu release, perhaps
4456 because the number of developers working on the core of the code is
4457 rather small and often busy elsewhere.

4459 <p

4462 <p
><strong
>Which free software do you use daily?
</strong
></p
>
4464 <p
>I am only using non-free software if I am forced to and run Debian
4465 on all my machines. For documents I prefer LaTeX and PGF/TikZ, then
4466 mutt and iceweasel for email respectively web browsing. At school I
4467 have Arduino and Fritzing in use for a micro controller project.

4469 <p
><strong
>Which strategy do you believe is the right one to use to
4470 get schools to use free software?
</strong
></p
>
4472 <p
>One of the major problems is the vendor lock-in from top to bottom:
4473 Especially in combination with ignorant government employees and
4474 politicians, this works out great for the
"market-leader
". The school
4475 administration here in Baden-Wuerttemberg is occupied by that vendor.
4476 Documents have to be prepared in non-free, proprietary formats. Even
4477 free browsers do not work for the school administration. Publishers
4478 of school books provide software only for proprietary platforms.
</p
>
4480 <p
>To change this, political work is very important. Parts of the
4481 political spectrum have become aware of the problem in the last years.
4482 However it takes quite some time and courageous politicians to
'free
'
4483 the system. There is currently some discussion about
"Open Data
" and
4484 "Free/Open Standards
". I am not sure if all the involved parties have
4485 a clue about the potential of these ideas, and probably only a
4486 fraction takes them seriously. However it might slowly make free
4487 software and the philosophy behind it more known and popular.

>Recently I have spent time with
4554 <a href=
"http://www.slxdrift.no/
">Skolelinux Drift AS
</a
> on speeding
4555 up a
<a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>
4556 Lenny installation using LTSP diskless workstations, and in the
4557 process I discovered something very surprising. The reason the KDE
4558 menu was responding slow when using it for the first time, was mostly
4559 due to the way KDE find application icons. I discovered that showing
4560 the Multimedia menu would cause more than
20 000 IP packages to be
4561 passed between the LTSP client and the NFS server. Most of these were
4563 NFS LOOKUP calls, resulting in a NFS3ERR_NOENT response. Because the
4564 ping times between the client and the server were in the range
2-
20
4565 ms, the menus would be very slow. Looking at the strace of kicker in
4566 Lenny (or plasma-desktop i Squeeze - same problem there), I see that
4567 the source of these NFS calls are access(
2) system calls for
4568 non-existing files. KDE can do hundreds of access(
2) calls to find
4569 one icon file. In my example, just finding the mplayer icon required
4570 around
230 access(
2) calls.
</p
>
4572 <p
>The KDE code seem to search for icons using a list of icon
4573 directories, and the list of possible directories is large. In
4574 (almost) each directory, it look for files ending in .png, .svgz, .svg
4575 and .xpm. The result is a very slow KDE menu when /usr/ is NFS
4576 mounted. Showing a single sub menu may result in thousands of NFS
4577 requests. I am not the first one to discover this. I found a
4578 <a href=
"https://bugs.kde.org/show_bug.cgi?id=
211416">KDE bug report
4579 from
2009</a
> about this problem, and it is still unsolved.
</p
>
4581 <p
>My solution to speed up the KDE menu was to create a package
4582 kde-icon-cache that upon installation will look at all .desktop files
4583 used to generate the KDE menu, find their icons, search the icon paths
4584 for the file that KDE will end up finding at run time, and copying the
4585 icon file to /var/lib/kde-icon-cache/. Finally, I add symlinks to
4586 these icon files in one of the first directories where KDE will look
4587 for them. This cut down the number of file accesses required to find
4588 one icon from several hundred to less than
5, and make the KDE menu
4589 almost instantaneous. I
'm not quite sure where to make the package
4590 publicly available, so for now it is only available on request.
</p
>
4592 <p
>The bug report mention that this do not only affect the KDE menu
4593 and icon handling, but also the login process. Not quite sure how to
4594 speed up that part without replacing NFS with for example NBD, and
4595 that is not really an option at the moment.

4625 Schweer, a valuable contributor to the project from Germany.
4627 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p

4629 <p
>I
've studied Mathematics at the university
'Ruhr-Universität
' in
4630 Bochum, Germany. Since
1981 I
'm working as a teacher at the school
4631 "<a href=
"http://www.westfalenkolleg-dortmund.de/
">Westfalen-Kolleg
4632 Dortmund
</a
>", a second chance school. Here, young adults is given
4633 the opportunity to get further education in order to do the school
4634 examination
'Abitur
', which will allow to study at a university. This
4635 second chance is of value for those who want a better job perspective
4636 or failed to get a higher school examination being teens.
</p
>
4638 <p
>Besides teaching I was involved in developing online courses for a
4639 blended learning project called
'abitur-online.nrw
' and in some other
4640 information technology related projects. For about ten years I
've been
4641 teacher and coordinator for the
'abitur-online
' project at my
4642 school. Being now in my early sixties, I
've decided to leave school at
4643 the end of April this year.
</p
>
4645 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4646 project?
</strong
></p
>
4648 <p
>The first information about Skolelinux must have come to my
4649 attention years ago and somehow related to LTSP (Linux Terminal Server
4650 Project). At school, we had set up a network at the beginning of
1997
4651 using Suse Linux on the desktop, replacing a Novell network. Since
4652 2002, we used old machines from the city council of Dortmund as thin
4653 clients (LTSP, later Ubuntu/Lessdisks) cause new hardware was out of
4654 reach. At home I
'm using Debian since years and - subscribed to the
4655 Debian news letter - heard from time to time about Skolelinux. About
4656 two years ago I proposed to replace the (somehow undocumented and only
4657 known to me) system at school by a well known Debian based system:
4658 Skolelinux.
</p
>
4660 <p
>Students and teachers appreciated the new system because of a
4661 better look and feel and an enhanced access to local media on thin
4662 clients. The possibility to alter and/or reset passwords using a GUI
4663 was welcomed, too. Being able to do administrative tasks using a GUI
4664 and to easily set up workstations using PXE was of very high value for
4665 the admin teachers.
</p
>
4667 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4668 Edu?
</strong
></p
>
4670 <p
>It
's open source, easy to set up, stable and flexible due to it
's
4671 Debian base. It integrates LTSP out-of-the-box. And it is documented!
4672 So it was a perfect choice.
</p
>
4674 <p
>Being open source, there are no license problems and so it
's
4675 possible to point teachers and students to programs like
4676 OpenOffice.org, ViewYourMind (mind mapping) and The Gimp. It
's of
4677 high value to be able to adapt parts of the system to special needs of
4678 a school and to choose where to get support for this.

4689 Annotator). At school (Skolelinux Lenny): Iceweasel, Gedit,
4690 LibreOffice.

4696 that doesn

4715 <p
>Det er store forskjeller på skolenes digitale tilstand, viser
4716 undersøkelsen Monitor
2011 som er laget på oppdrag fra
4717 Kunnskapsdepartementet. Dette har ført til debatt om PC-tilgangen i
4718 skolen, og om de med Linux i skolen gjør det bedre bedre eller
4719 dårligere enn snittet i landet.
</p

4721 <p
>Nå har vi tallene. Skoler med Linux har
36% større PC-tetthet en
4722 landsgjennomsnittet. På spørsmål hvorfor skoler med Linux har større
4723 PC-tetthet, observerer Paul Reidar Løsnesløkken som er IKT-konsulent i
4724 Nord-Odal:
</p

4726 <p

>"Vi erfarer at klienter med Skolelinux har god funksjon
4727 til de er
8 til
10 år gamle. Dette er omtrent dobbelt så lenge som
4728 andre løsninger, og skolene får mer datautstyr for
4729 pengene.
"</blockquote
></p
>
4731 <p
>Undersøkelsen baserer seg på
56 skoler som har gjort det offentlig
4732 at de kjører Skolelinux eller annen Linux-utgave. De kan også ha PC-er
4733 med Windows i skolenettet. Når en sammenligner PC-tetthetene på
4734 skolene i kommunene Flora, Harstad, Kongsvinger, Narvik, Nittedal,
4735 Nord-Odal og Randaberg, er det i snitt
2,
28 elev pr. PC på skolene med
4736 Linux. På landsbasis er det
3.11 elev per PC i grunnskolen, i følge
4737 side
95 i Monitor-rapporten for

36% større
4738 PC-tetthet i skoler med Linux.

4742 <p
>Skolelinux har til hensikt å gi alle barn full tilgang til
4743 skoleaktuelle dataprogram på sitt eget morsmål. Derfor følger det med
4744 godt over
100 skoleaktuelle programmene laget for læring. De fleste
4745 programmene er oversatt til over
50 språk. Elevene skal også kunne
4746 studere alle sider av dataprogrammene. Derfor følger også kildekode
4747 med. Elever med interesse kan lære av eksperter som har laget
4748 systemet. Dette med enkelt programmering i læreprogram som KTurtle,
4749 til profesjonelle verktøy som Qt Creator eller Java.

4751 <p
>Skolelinux er laget for sentralisert drift, der alt teknisk
4752 administrasjon av alle skolene kan gjøres sentralt fra kommunehuset
4753 eller sentralt i en region. F.eks. drifter to-tre personer
70.000
4754 skoledatamaskiner på
200 skoler i delstaten Extremadura i
4755 Spania. Etter velykket bruk av Debian Edu i skolen, legger delstaten
4756 over til Debian på
40.000 datamaskiner i administrasjonen. Det er idag

>I serien med intervjuer av folk i
4796 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet, får vi
4797 denne gangen høre fra en IKT-ansvarlig som har brukt Skolelinux i
4798 mange år, og vært storfornøyd med erfaringene så langt.
</p
>
4800 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
4802 <p
>Mitt navn er Roy-Arne Myhre og jeg er
42 år. Jeg er ansatt hos
4803 <a href=
"http://www.sandskole.no/
">Sand skole
</a
> (Balsfjord kommune)
4804 og har stort sett vært det siden
1990. Jeg er IKT ansvarlig ved
4805 skolen i
40% stilling –
10% undervisning – musikk.
</p
>
4807 <p
>Ved skolen er det ca
100 elever og ca
18 lærere +
4 assistenter i
4808 hele og delte stillinger. Alle lærerne har bærbar PC (dessverre med
4809 Win Vista) – assistenter har tilgang til egne. Vi benytter Fronter i
4810 det daglige arbeidet. Vi har ca
90 elevmaskiner som fungerer til
4811 daglig opp mot Linux server (XFCE) som driftes av
4812 <a href=
"http://www.bzz.no/
">BzzWare AS
</a
> via nett. Maskinparken
4813 består kun av brukt utstyr for elevene – og noe av dette begynner å
4814 bli vel gammelt selv som halvtykke klienter.
</p
>
4816 <p
><strong
>Hvordan kom du i kontakt med
4817 Skolelinux-prosjektet?
</strong
></p
>
4819 <p
>Vi kom første gang i kontakt med Skolelinux rundt
1997. Den gang
4820 var det oppstart-disketter i hver maskin, ikke mulighet for lyd og
4821 video, gamle nettverkskort og mye plundring. Vi hadde en ihuga
4822 forelder med som pådriver, forsker og inspirator for hele opplegget.
4823 Selv ante jeg knapt at Skolelinux fantes, men han var av den
4824 utforskende typen, og fikk både meg og skolelederen i trua på at dette
4825 var ting som kunne fungere. Etter dette har det gått gradvis
4826 framover; flere maskiner er hentet inn gjennom bl.a
4827 <a href=
"http://www.greentech.no/
">Greentech
</a
> og utrangert utstyr
4828 fra høgskole / Avinor og private givere. Når maskinene ble for trege
4829 for nye Windows-versjoner, sto vi klare til å putte dem i nettverket
4830 vårt. Dette betyr at vi i dag har
1:
1 dekning av maskiner på
4831 ungdomstrinnet og bedre enn
1:
2 på barnetrinnet. Dette er vi veldig
4832 fornøyd med, og vi kan ikke se for oss hverdagen som ville vært
4833 alternativet ved bruk av Windows med sine lisenser pr. Bruker/maskin.
4834 Da ville vi nok vært tilbake til
1-
2 maskiner pr klasserom med de
4835 negative konsekvenser det ville hatt for undervisningsformene våre. Vi
4836 kan ha en hel klasse i prosjektjobbing eller individuell jobbing
4837 samtidig – vi kan avholde tentamen og eksamen uten
4838 logistikkproblemer.
</p
>
4840 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
4842 Hvor skal jeg begynne... Stabiliteten er et nøkkelord - det bare
4843 virker. Har du først fått en server med Skolelinux opp og gå, så må
4844 det en maskinarefeil eller sabotasje til for å stoppe den. Det at man
4845 kan bruke eldre maskiner som normalt sett ville gått på dynga, er også
4846 glimrende - billig for skoler med dårlig økonomi og bra for miljøet
4847 siden vi gjenbruker utstyr i stedet for å skaffe nytt. Vi ville aldri
4848 hatt mulighet til å operere med det maskinantallet vi har pr i dag
4849 hvis det ikke var for Skolelinux - så tilgjengelighet er et annet
4850 nøkkelord. Et tredje moment er sikkerhet og brukertilgang. Alle
4851 brukerer opererer med egne brukernavn og passord, samt egne
4852 brukerområder som kan tilpasses for både enbrukertilgang og for
4853 samarbeid med andre.
4855 Elever har godt av å se at det finnes andre alternativer enn de som
4856 storindustrien selger på lisensbasis - på den måten trenes de opp til
4857 å se flere muligheter og å foreta valg ut fra flere opsjoner.
4859 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
4861 <p
>Ulempene med Skolelinux er nok utbredelsen og mangelen på kjennskap
4862 til dette i skolenorge. De som skal ta økonomiske avgjørelser rynker
4863 på nesen og vil gå for det kjente og «sikre» selv om det koster mye
4864 mer. Man får rett og slett litt hetta av å ikke kunne noe – og unngår
4865 dette for enhver pris.
</p
>
4867 <p
>I tillegg er mye av linux-systemet administrert av tekstkommandoer
4868 og er lite intuitiv/visuell for oss som ikke er «inne i»
4869 kildekodene». Så problemet er nok mye godt at de som
4870 utarbeider/drifter Skolelinux ikke helt klarer å sette seg ned på
4871 skoleadministratorens nivå når det gjelder problemer og
4872 utfordringer. Men dette er nok en utfordring alle administratorer
4873 sliter med uansett OS.
</p
>
4875 <p
>Derfor har vi valgt å støtte oss til BzzWare AS for assistanse i
4876 drifta slik at jeg har kunnet konsentrere meg mer om kabling, skifting
4877 av komponenter, veiledning av lærere og elever, vedlikehold av
4878 skrivere og annen daglig drift.
</p
>
4880 <p
>Elevene mestrer Skolelinux helt fint. Så lenge Internett
4881 (Iceweasel) og Libreoffice (Openoffice) fungerer er
90% av
4882 skolehverdagen velfungerende. I tillegg brukes jo en del av den
4883 pedagogiske programpakken bla. i forhold til matematikk og geografi,
4884 men det er såpass mye bra på nett om dagen, så disse programmene er
4885 mer som krydder å regne.
</p
>
4887 <p
>Jeg skulle ønske neste versjon av Skolelinux kunne komme litt
4888 mindre stappet med programmer, for halvparten blir aldri brukt, eller
4889 fungerer ikke uansett. Hva med et pedagogisk panel av lærere/IKT
4890 ansvarlige som kunne sagt: disse programmene skal være standard, så
4891 får resten være slike man kan legge til ved behov – det kan lett bli
4892 en jungel å bevege seg i.
</p
>
4894 <p
>Jeg ønsker meg også en mer grafisk versjon av
4895 <a href=
"http://bzz.no/lwat/trac/trac.cgi
">Lwat
</a
> hvor man kan krysse
4896 ut de som f.eks ikke skal ha internett-tilgang en dag pga
4897 eksamen/tentamen, samt en noe enklere brannmurløsning hvor man kan
4898 stenge for en del (få) sider på en enkel måte. Jeg liker godt
4899 Skolelinux sin ideologi om at filteret skal trenes i hodet på eleven –
4900 men av og til skulle jeg ønske at f.eks Facebook og Youtube kunne vært
4901 koblet vekk en periode for å få bedre utnyttelse av tid og
4902 ressurser. Disse to nettstedene er nok mye av årsaken til at mange
4903 lærere holder igjen databruken noe mer enn man kunne ønske.
</p
>
4905 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
4907 Jeg benytter nesten bare fri programvare til daglig. LibreOffice,
4908 Iceweasel (Firefox), Thunderbird til e-post og Gimp til
4909 bildebehandling. Vi har PHP-Nuke-oppsatt hjemmeside. Det eneste som
4910 jeg ikke har fått helt til enda er videoredigering - her må man vel
4911 innrømme at Mac er hakket over, men da er vi igjen over på å se hva
4912 som egner seg best, og ta valg ut fra det. Folk flest lever i
4913 villfarelsen om at regneark HETER Excel og tekstbehandling HETER
4914 Word. Dette er en misforståelse som jeg bruker mye energi på å
4915 diskutere og
"åpne sinn
" på Microsoft-slaver. Dessverre er det mange
4916 IKT-ansvarlige som også har låst seg på at det eneste saliggjørende er
4917 Bill G sine produkter.
4919 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
4920 skoler til å ta i bruk fri programvare?
</strong
></p
>
4922 <p
>For å komme lenger i utbredelsen av Skolelinux tror jeg det må mer
4923 fram i nasjonale medier, samt komme bedre fram hva økonomien i dette
4924 valget vil være – samt mulighetene. Fri programvare er en berikelse og
4925 gjør oss i stand til å utføre arbeidet i skolen uten å måtte legge
4926 igjen tusener på tusener i Bill Gates lomme.. Få ETT nettsted med
4927 forståelig veiledning av installasjon/oppgradering og ETT forum med
4928 konkrete feilrettinger og problemer, så tror jeg vi kunne kommet et
4929 par skritt framover. Ellers tror jeg bare at ildsjelene må fortsette å
4930 skinne – kanskje flere enn oss følger etter på veien.

>Den siste uka har det vært en del skriverier om hvor store
4965 forskjeller det er mellom skolene når det gjelder digital kompetanse.

"http://www.digi.no/
891660/bekymret-for-it-i-skolen
">oppslaget
4968 i Digi
</a
>. Diskusjonen fikk meg til å bli litt nysgjerrig på om
4969 Linux-skoler har større PC-tettet enn snittet i landet. Grunnlaget
4970 for diskusjonen har vært undersøkelsen
4971 <a href=
"https://iktsenteret.no/ressurser/monitor-
2011-skolens-digitale-tilstand
">Monitor
4972 2011</a
>, som bruker informasjon fra
4973 <a href=
"https://www.wis.no/gsi
">Grunnskolens Informasjonssystem
</a
>
4974 (GSI). GSI-data kan lastes ned fra web og jeg lastet ned en Excel-fil
4975 (intet åpen standard-valg tilgjengelig) med navn på alle skoler,
4976 hvilke kommune de befinner seg i og hvor mange elever pr. elev-PC de
4977 har rapportert inn. For å få en ide om svaret trenger jeg deretter å
4978 vite hvilke skoler i landet som bruker Linux, slik at jeg kan slå dem
4979 opp i GSI og finne ut hvor stor PC-tetthet de har.
</p
>
4981 <p
>Jeg vet om skoler i Balsfjord, Flora, Harstad, Kongsvinger, Narvik,
4982 Nittedal, Nord-Odal, Randaberg og Sunndal som bruker Skolelinux eller
4983 andre Linux-varianter. Jeg tror det er flere enn de
56 skolene jeg
4984 har klart å identifisere de siste dagene, men har ikke klart å få det
4985 bekreftet med offentlige kilder.
</p
>
4987 <p
>Monitor
2011-rapporteres side
95 forteller at det
"ifølge GSI
4988 (
20120-
2011) er det
3,
11 elever per datamaskin når vi tar med alle
4989 grunnskoler (
1.-
10.trinn)
". For de
56 Linux-skolene jeg har klart å
4990 koble mot informasjon i GSI er det
2,
28 elever per elevdatamaskin,
4991 hvilket betyr at det er
36% høyere PC-tetthet på Linux-skoler enn
4992 landsgjennomsnittet. Linux-skolen med høyest tettet blant de jeg har
4993 notert -skole er Flora ungdomsskule i Flora kommune med
0.82 elev
4994 pr. PC (
482 elever,
588 elevdatamaskiner).
</p
>
4996 <p
>Skolelinux gir datamaskiner lengre levetid, og en kan dermed få
4997 flere operative datamaskiner for samme budsjett, i tillegg til en
4998 rekke andre fordeler. Kan det være forklaringen på forskjellen?
</p
>
5000 <p
>Tallene må tas med en liten klype, da GSI ser ut til å ha endel
5001 feilføringer. Jeg synes i hvert fall en skole med
423 elever og
9
5002 elevmaskiner ser mistenkelig ut. Eller en skole med
346 elever,
0
5003 elevmaskiner, som er et annet ekstremt eksempel jeg fant.

5023 <p
>I teach ICT part time at the Rudolf Steiner School in Kings
5024 Langley, near London, UK. Previously I worked as a technical
5025 author/trainer while my children attended the school, and I also
5026 contributed to the Schoolforge UK community with the aim of
5027 encouraging UK schools to adopt free/open source software. Five or six
5028 years ago we had about
50 schools interested in some way, but we
5029 weren
't able to convert many of them into sustainable
5030 installations.
</p
>
5032 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5033 project?
</strong
></p
>
5035 <p
>Skolelinux had two representatives at an early Edubuntu meeting in
5036 London which I attended. However at that time our school network had
5037 just been installed using CentOS, LTSP
4 and GNOME. When LTSP
5 came
5038 along we switched to Edubuntu thin client servers so now we have a
5039 mixed environment which includes Windows PCs and student laptops, as
5040 well as their MacBooks and iPads. However, the proprietary systems
5041 have always been rather problematic, and we never built a GUI for the
5042 LDAP server, so when I discovered Skolelinux is configured for all
5043 these things we decided to try it.
</p
>
5045 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5046 Edu?
</strong
></p
>
5048 <p
>By far the biggest advantage is the Debian Edu community. Apart
5049 from that I have always believed in the same
"sustainable computing
"
5050 goals that Skolelinux is built on: installing Linux on computers which
5051 would otherwise be thrown away, to provide a reliable, secure and
5052 low-cost IT environment for schools. From my own experience I know
5053 that a part-time person can teach and manage a network of about
25
5054 Linux computers, but it would take much more of my time if we had
5055 proprietary software everywhere.

</strong

5060 <p
>As a newcomer I
'm just finding out who
's who in the community and
5061 how you
're organised, and what your procedures are for dealing with
5062 various things such as editing manual pages and so-on. The only
5063 English language mailing list seems to be for developers as well as
5064 users, so my inbox needs heavy pruning each day!
</p

5066 <p
><strong
>Which free software do you use daily?
</strong
></p
>
5068 <p
>Besides the software already mentioned at school we use Samba,
5069 OpenLDAP, CUPS, Nagios and Dansguardian for the network, and on the
5070 desktops we have LibreOffice, Firefox, GIMP and Inkscape. At home I
5071 use Ubuntu and an Android
4 eePad Transformer (but I
'm not sure if
5072 that counts...)
</p
>
5074 <p
><strong
>Which strategy do you believe is the right one to use to
5075 get schools to use free software?
</strong
></p
>
5077 <p
>That
's a tough question! For very many years UK schools installed
5078 and taught only proprietary software, so that at the highest levels
5079 the notion of
"computer
" means simply
"proprietary office
5080 applications
". However, schools today are experiencing budget
5081 constraints, and many are having to think hard about upgrading Windows
5082 XP. At the same time, we have students showing teachers how to use
5083 iPads, MacBooks and Android, so the choice of operating system is no
5084 longer quite so automatic. What is more, our government at last
5085 realised that we need people with programming skills, so they
're
5086 putting coding back in the curriculum! And it
's encouraging that the
5087 first
10,
000 Raspberry Pi units sold out in
2 hours.
</p
>
5089 <p
>I don
't really know what strategy is going to get UK schools to use
5090 free software, but building an active community of Skolelinux/Debian
5091 Edu users in this country has to be part of it.

>Documentation in Debian Edu is provided in several languages, and
5101 it is important to make it both easy to contribute and to keep the
5102 translated versions in sync. To do this we have come up with what we
5103 believe is a very efficient work flow.
</p
>
5107 <li
>The documentation is written in a
5108 <a href=
"http://moinmo.in
">moinmoin wiki
</a
> (see for example
5109 <a href=
"http://wiki.debian.org/DebianEdu/Documentation/Squeeze
">the
5110 Squeeze release manual
</a
>) with support for exporting the content as
5111 docbook XML.
</li
>
5113 <li
>This docbook document is given to po4a to extract a gettext style
5114 .pot file with the content, which in turn is used to create .po files
5115 with the translated text.
</li
>
5117 <li
>The .po files are given to translators, and they can always tell
5118 which part of the original wiki document is new or changed. They can
5119 use their normal translation tools like lokalize or poedit to write
5120 the translation. There is even a system in place to handle translated
5123 <li
>The translated .po files are combined with the original docbook
5124 XML document using po4a to create a translated docbook document.
</li
>
5126 <li
>The final step is to use all the generated docbook files and
5127 create PDF and HTML version of the original and translated documents.
</li
>
5131 <p
>This setup work very well, but have a few issues. The biggest
5132 issue is that
<a href=
"http://moinmo.in/DocBook
">the docbook support
5133 we use in moinmoin
</a
> is not actively maintained. The docbook
5134 support is also buggy, and our build system contain workarounds to
5135 make sure the generated docbook is usable despite these bugs.
</p
>
5137 <p
>If you want to have a look at our setup, it is all there in the

5154 hatt med, og har sikkert skrevet noe tull på lysarkene som jeg ennå
5155 ikke har oppdaget. Denne presentasjonen ble smurt ihop på veldig kort
5156 tid, og jeg rakk ikke finpusse den. Håper den kan være lærerik

5194 <p
>Jeg hørte om det først når jeg jobbet i Redpill Linpro. Men jeg
5195 har også en datter som går på en friskole, som også bruker Skolelinux.
5196 Som kjent har ikke friskoler de samme økonomiske rammebetingelsene som
5197 offentlige skoler, så for dem var det det absolutt beste alternativet.
5198 De anser også Skolelinux som et stabilt system, som bare går og går (i
5199 motsetning til det lille Windows-baserte nettverket de har på
5200 admin-siden).

5205 lydløse og raskere arbeidsstasjoner som er bedre i klasserommet.
5206 Lengre levetid på PC
'er. Store besparelser på maskinvare og drift. Og
5207 så klart fjerning av alle lisenskostnader. Personlig synes jeg også at
5208 mange av programmene er bedre enn alternativene. Men dette er ofte en
5209 smakssak og avhengig om man må ha det man er vant til fra før.

5214 kompatibilitet med arbeidsstasjoners/bærbare maskiner sine
5215 nettverksdrivere eller skjermkort. Men dette løser vi i skolene ved
5216 standardisering. Ellers er det få, om nesten ingen, av de kjente
5217 maskinvare / infrastruktur leverandørene til fylkes- / kommuner som
5218 tilbyr denne plattformen. Skal dette endre seg så må kommunene selv
5219 sette slike krav til leverandørene.

5231 <p
>Fortsette å presentere flere av de gode eksemplene hvor Debian Edu
5232 / Skolelinux brukes i kommuner og enkeltskoler. Vi må få bedre frem
5233 at det er mulig tilknytte både Windows og Mac klienter på denne
5234 plattformen (selv om det vil øke driftskostnadene). Dette gjøres
5235 mange steder. Spesielt er det mange lærere som ønsker å bruke
5236 Windows/Mac-bærbare, gjerne som sin private PC også. Det er også mulig
5237 for kommunen å integrere med Active Directory i stedet for OpenLDAP
5238 som kommer med ut av boksen (selv om også dette øker kostnadene).
5239 Dette vil muligens bidra til å fjerne noe motstand hos noen
5240 potensielle brukere / driftpersonell for å ta i bruk noe
5241 nytt. Fremveksten av mobile brukere og nettbrett går i vår favør.
5242 Brukerne blir kjent og vant til flere nye operativsystemer /
5243 brukergrensesnitt. Så utviklerfellesskapet bør jobbe videre med å
5244 integrere flere nye klienttyper, som ultra lav-kostklienter og
5245 nettbrett (blant annet fri programvare-alternativet

>Inspired by
<a href=
"http://raphaelhertzog.com/tag/interview/
">the
5277 interview series
</a
> conducted by Raphael, I started a Norwegian
5278 interview series with people involved in the Debian Edu / Skolelinux
5279 community. This was so popular that I believe it is time to move to a
5280 more international audience.
</p
>
5282 <p
>While
<a href=
"http://www.skolelinux.org/
">Debian Edu and
5283 Skolelinux
</a
> originated in France and Norway, and have most users in
5284 Europe, there are users all around the globe. One of those far away
5285 from me is Nigel Barker, a long time Debian Edu system administrator
5286 and contributor. It is thanks to him that Debian Edu is adjusted to
5287 work out of the box in Japan. I got him to answer a few questions,
5288 and am happy to share the response with you. :)
5291 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
5293 <p
>My name is Nigel Barker, and I am British. I am married to Yumiko,
5294 and we have three lovely children, aged
15,
14 and
4(!) I am the IT
5295 Coordinator at Hiroshima International School, Japan. I am also a
5296 teacher, and in fact I spend most of my day teaching Mathematics,
5297 Science, IT, and Chemistry. I was originally a Chemistry teacher, but
5298 I have always had an interest in computers. Another teacher teaches
5299 primary school IT, but apart from that I am the only computer person,
5300 so that means I am the network manager, technician and webmaster,
5301 also, and I help people with their computer problems. I teach python
5302 to beginners in an after-school club. I am way too busy, so I really
5303 appreciate the simplicity of Skolelinux.
</p
>
5305 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
5306 project?
</strong
></p
>
5308 <p
>In around
2004 or
5 I discovered the ltsp project, and set up a
5309 server in the IT lab. I wanted some way to connect it to our central
5310 samba server, which I was also quite poor at configuring. I discovered
5311 Edubuntu when it came out, but it didn
't really improve my setup. I
5312 did various desperate searches for things like
"school Linux server
"
5313 and ended up in a document called
"Drift
" something or other. Reading
5314 there it became clear that Skolelinux was going to solve all my
5315 problems in one go. I was very excited, but apprehensive, because my
5316 previous attempts to install Debian had ended in failure (I used
5317 Mandrake for everything - ltsp, samba, apache, mail, ns...). I
5318 downloaded a beta version, had some problems, so subscribed to the
5319 Debian Edu list for help. I have remained subscribed ever since, and
5320 my school has run a Skolelinux network since Sarge.
</p
>
5322 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
5323 Edu?
</strong
></p
>
5325 <p
>For me the integrated setup. This is not just the server, or the
5326 workstation, or the ltsp. Its all of them, and its all configured
5327 ready to go. I read somewhere in the early documentation that it is
5328 designed to be setup and managed by the Maths or Science teacher, who
5329 doesn
't necessarily know much about computers, in a small Norwegian
5330 school. That describes me perfectly if you replace Norway with
5333 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
5334 Edu?
</strong
></p
>
5336 <p
>The desktop is fairly plain. If you compare it with Edubuntu, who
5337 have fun themes for children, or with distributions such as Mint, who
5338 make the desktop beautiful. They create a good impression on people
5339 who don
't need to understand how to use any of it, but who might be
5340 important to the school. School administrators or directors, for
5341 instance, or parents. Even kids. Debian itself usually has ugly
5342 default theme settings. It was my dream a few years back that some
5343 kind of integration would allow Edubuntu to do the desktop stuff and
5344 Debian Edu the servers, but now I realise how impossible that is. A
5345 second disadvantage is that if something goes wrong, or you need to
5346 customise something, then suddenly the level of expertise required
5347 multiplies. For example, backup wasn
't working properly in Lenny. It
5348 took me ages to learn how to set up my own server to do rsync backups.
5349 I am afraid of anything to do with ldap, but perhaps Gosa will
5352 <p
><strong
>Which free software do you use daily?
</strong
></p
>
5354 <p
>Nowadays I only use Debian on my personal computers. I have one for
5355 studio work (I play guitar and write songs), running AV Linux
5356 (customised Debian) a netbook running Squeeze, and a bigger laptop
5357 still running Skolelinux Lenny workstation. I have a Tjener in my
5358 house, that
's very useful for the family photos and music. At school
5359 the students only use Skolelinux. (Some teachers and the office still
5360 have windows). So that means we only use free software all day every
5361 day. Open office, The GIMP, Firefox/Iceweasel, VLC and Audacity are
5362 installed on every computer in school, irrespective of OS. We also
5363 have Koha on Debian for the library, and Apache, Moodle, b2evolution
5364 and Etomite on Debian for the www. The firewall is Untangle.
</p
>
5366 <p
><strong
>Which strategy do you believe is the right one to use to
5367 get schools to use free software?
</strong
></p
>
5369 <p
>Current trends are in our favour. Open source is big in industry,
5370 and ordinary people have heard of it. The spread of Android and the
5371 popularity of Apple have helped to weaken the impression that you have
5372 to have Microsoft on everything. People complain to me much less about
5373 file formats and Word than they did
5 years ago. The Edu aspect is
5374 also a selling point. This is all customised for schools. Where is the
5375 Windows-edu, or the Mac-edu? But of course the main attraction is
5376 budget.The trick is to convince people that the quality is not
5377 compromised when you stop paying and use free software instead. That
5378 is one reason why I say the desktop experience is a weakness. People
5379 are not impressed when their USB drive doesn
't work, or their browser
5380 doesn
't play flash, for example.

>Many years ago, the
<a href=
"http://www.skolelinux.org/
">Skolelinux
5427 / Debian Edu project
</a
> initiated a student project to create a tool
5428 for making stop motion movies. The proposal came from a teacher
5429 needing such tool on Skolelinux. The project, called
"stopmotion
",
5430 was manned by two extraordinary students and won a school award and a
5431 national aware with this great project. The project was initiated and
5432 mentored by Herman Robak, and manned by the students Bjørn Erik Nilsen
5433 and Fredrik Berg Kjølstad. They got in touch with people at Aardman
5434 Animation studio and received feedback on how professionals would like
5435 such stopmotion tool to work, and the end result was and is used by
5436 animators around the globe. But as is usual after studying, both got
5437 jobs and went elsewhere, and did not have time to properly tend to the
5438 project, and it has been lingering for a few years now. Until last
5441 <p
>Last year some of the users got together with Herman, and moved the
5442 project to Sourceforge and in effect restarted the project under a new

"http://sourceforge.net/projects/linuxstopmotion/
">linuxstopmotion
</a
>.
5445 The name change was done to make it possible to find the project using
5446 Internet search engines (try to search for
'stopmotion
' to see what I
5447 mean). I
've been following
5448 <a href=
"https://lists.sourceforge.net/lists/listinfo/linuxstopmotion-community

5527 <p
>Knut Yrvin her. Jobber i Nokia med å fremme rammeverket Qt og QML
5528 med tilhørende utviklerverktøy. Rollen er som leder av
5529 friprog-samfunn. I fjor var jeg med å legge om utviklingen av Qt til
5530 åpen forvaltning. På den måten kan alle som bidrar til Qt gjøre det
5531 på like vilkår. Nå er det

">over
5533 1000 utviklere
</a
> som bidrar til Qt. Med overgangen til åpen
5534 forvaltning er utviklingen av Qt mer åpen enn Linux-kjernen.
</p
>
5536 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
5538 <p
>Jeg var en av initiativtagerne til Skolelinux i
2001. Skolene slet
5539 med både utstyr og Internett-tilgang. De klarte ikke å møte
5540 forventningene til data i skolen. Driften av PC-ene var uholdbar. Som
5541 regel hadde rektor pekt ut en ivrig lærer til å passe på PC-ene,
5542 gjerne naturfaglæreren. Mange lærere jobbet mye ubetalt overtid for å
5543 vedlikeholde
30-
40 datamaskiner på hver sin skole. Med
300 elever og
5544 lærere som brukere, blir det fort mye mer arbeid enn de
4-
8 timene de
5545 kunne bruke på PC-drift. Skolene hadde kun en femtedel av
5546 IT-budsjettet som ble brukt på PC-ene i rådhuset.
</p
>
5548 <p
>Vi erfarte at skolene hadde mye datautstyr som stod ubrukt. Skolene
5549 manglet penger til Microsoft-lisenser. Selv med solide skolerabatter,
5550 kostet Microsoft-lisensene gjerne like mye som PC-ene i seg selv over
5551 en periode på
5-
6 år.
</p
>
5553 <p
>Viktigheten av språklig mangfold og pedagogiske programmer var også
5554 viktig for oss. Vi oversatte mange skoleaktuelle programmer til
5555 nynorsk, nordsamisk og bokmål. Dette lenge før andre tok denne
5556 oppgaven seriøst. Allerede etter ett år hadde vi etablert et helt
5557 arsenal av skoleaktuelle programmer på nynorsk, bokmål og
5558 nordsamisk. Vi spredde vår ide om språklig mangfold til de andre frie
5559 prosjekter internasjonalt. Resultatene ser vi i mange land. Det er de
5560 frie programmene som kommer på brukernes morsmål. Det er en av flere
5561 gode grunner til at fri programvare som LibreOffice, VLC, KDE og
5562 Firefox konkurrerer ut godseid programvare mange steder i verden.
</p
>
5564 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
5566 <p
>Fordelene er at Skolelinux tilbyr over
100 skoleaktuelle programmer
5567 på de norske språkene, uten ett øre i lisenskostnader. Systemet gir
5568 enormt lave driftskostnader med diskløse arbeidsstasjoner og bærbare
5569 med roaming. Skolelinux krever også mindre av maskinvaren.
</p
>
5571 <p
>Man kan fint kjøre systemet med
512 MB RAM på en bærbar PC sammen
5572 med en nettvideo i nettleseren og en presentasjon med
5573 LibreOffice. Konkurrerende system krever fort
2 GB RAM for å få til
5574 noe tilsvarende uten at det går ufattelig tregt. Skal man gjøre noe
5575 nyttig, krever konkurrentene til Linux mye større harddisk. Skoler har
5576 rapportert at de fort har fått
50% flere nye maskiner om de velger
5577 Linux. Dette i tillegg til de årlige besparelsene ved å unngå
5578 lisensbetaling til godseid programvare.
</p
>
5580 <p
>De lave driftskostnadene gjør at delstater i Europa har titusener
5581 av datamaskiner med Skolelinux i skolen. F.eks. er det under ti
5582 personer som drifter
70.000 PC-systemer i skolene i Extremadura i
5583 Spania. Det er slett ikke uvanlig at norske kommuner har
1500-
2000
5584 datamaskiner med Skolelinux. Driften tar ett årsverk. Slår flere
5585 kommuner seg sammen, kan de få samme sentraliserte stordriftsfordeler
5586 som delstater i Tyskland og Spania. Delstater som kjører Skolelinux
5587 på alle skolene. Bare noen få personer sentraldrifter titusenvis av
5590 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
5592 <p
>Den største ulempen for Skolelinux er motstand mot Linux fra
5593 IT-sjefer i det offentlige. Dette er ledere som holder innlegg som
5594 snytt ut av evangelist-håndboka til Microsoft. Dette gjøres i ett
5595 arbeidsmarked med stor vekst i etterspørselen etter Linux-fagfolk i
5596 privat sektor. Etterspørselen har økt mer enn noe annet tekniske yrke
5597 siste tiåret. Åtte av ti ledere vil ansette Linux-fagfolk i
2012,
5598 rapporterer jobbnettstedet Dice.com på oppdrag av Linux
5599 Foundation.
</p
>
5601 <p
>Det mangler
16.000 ingeniører og IKT-fagfolk i Norge rapporterte
5602 arbeids- og velferdsetaten NAV. Linux-fagfolk kan velge svært
5603 interessante jobber med alt fra apps på ledende mobilsystem laget med
5604 Linux, sky- tjenester eller web-applikasjoner. De raskest voksende
5605 teknologiselskapene i verden er ute etter Linux-fagfolk. Det være seg
5606 Amazon, Google, Facebook og IBM for å nevne noen. Linux er kritisk
5607 for å sikre veksten i markedet. Det sier seg selv at lønningene og
5608 jobbmulighetene er bedre enn for andre tekniske yrker.
</p
>
5610 <p
>Skal man lage apps for mobilen, smart-TV-en eller
5611 underholdningssystemet i bilen eller på flyet, er det Linux som
5612 gjelder. Med en slik konkurranse om Linux-kompetansen, kombinert med
5613 motstanden mot Linux hos mange IT-sjefer i offentlig sektor, så
5614 hindrer kommunene rekruttering av flere Linux- fagfolk. Skolene blir
5615 tvunget til å velge dyrere og mindre komplette IT-system. De har
5616 blitt hengende igjen slik IT var på begynnelsen av
2000- tallet. Dette
5617 fordi IT-ledere ikke har tilpasset seg markedet det siste tiåret.
</p
>
5619 <p
>Når det er sagt, er Skolelinux svært enkelt å lære seg også for de
5620 som ikke kan. Det viser alle lærerne som drifter systemet for
5621 hundrevis og tusenvis av systemer. Det meste er på plass rett ut av
5622 boksen. I tillegg er det solid med dokumentasjon med god hjelp på
5623 nettet. Det er mange kommuner som har ansatt en lærer som først lærte
5624 Skolelinux på sin skole, for så å drifte alle PC-ene i kommunen med
5625 Skolelinux. Det kan fort være snakk om
1000-
3000 datamaskiner på
10-
15
5626 skoler som sentraldriftes med en stilling. Står man ordentlig fast,
5627 kan man også kjøpe profesjonell hjelp fra selskap som støtter
5628 Skolelinux. Det er flere slike selskap i Norge og i utlandet.
</p

5630 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
5632 <p
>Qt SDK, LibreOffice, Firefox, VLC og KDE-skrivebordet. Dette på et
5633 Debian-basert GNU/Linux-system. Jeg bruker også noen morsomme
5634 3D-spill. Idag kan jeg velge mellom over
30.000 Linux-programmer. Det
5635 finnes ikke tid i livet å undersøke alle valgmulighetene. Derfor er
5636 det bra med Skolelinux i skolen, da utvalget av programmer er
5637 begrenset til hva som er aktuelt i skolefagene.
</p
>
5639 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
5640 skoler til å ta i bruk fri programvare?
</strong
></p
>
5642 <p
>Vi må selge hele Skolelinux forhåndsinstallert på maskinvare i hele
5643 pakker med
50-
100-
1000 PC-klienter med servere. Dette kan selges til
5644 enkeltskoler eller hele kommuner. Pakken må inneholde tjenermaskiner,
5645 svært rimelige diskløse arbeidsstasjoner, nettbrett med Plasma Active,
5646 og bærbare med roaming. Alt er godt testet med Debian. I et slikt
5647 anbud er det mulig å legge til sentraliserte drifts- og
5648 støttetjenester.
</p
>
5650 <p
>Man bør også selge sky-tjenester som læreadministrative systemet
5651 Moodle og driftsovervåking. I tillegg så bør man slenge seg på med
5652 presentasjoner de gangene LibreOffice og andre friprog-produkter
5653 selges til kommuner.

5691 <p
>Jeg kom i kontakt med prosjektet i
2009, da jeg ble ansatt i
5692 stiftelsen Åpne kontorprogram på norsk for å oversette og teste den
5693 norske utgaven av OpenOffice.org. Arbeidet har hele tiden vært
5694 koordinert sammen med Skolelinux, og mange av de samme menneskene er
5695 involvert, så på den måten ble jeg en del av den utvidede

><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
5700 <p
>Skolelinux handler i likhet med utdanningssektoren om å dele
5701 kunnskap med andre, og det er dette som er hovedstyrken til
5702 prosjektet. Selv om Skolelinux hovedsaklig er involvert i utvikling
5703 av programvare, er det også et sted der man kan utfolde seg uavhengig
5704 av bakgrunn og ferdigheter.

5706 <p

5708 <p
>Liten utbredelse og manglende støtte fra leverandører som leverer
5709 pedagogisk programvare til skolebruk. Kunne kanskje hatt flere
5710 verktøy som letter administrasjonen ytterligere, slik at også mindre
5711 erfarne databrukere kan utføre lett vedlikehold og rutinejobber.

1 med KDE4. Men
5718 hvis jeg skal dra fram noen flere eksempler så er nok Mozilla Firefox
5719 og Thunderbird to av de jeg bruker mest. I tillegg er jeg en flittig
5720 bruker av OpenSSH, Irssi, Midnight Commander, Git, Subversion,
5721 Translation Toolkit og Super Maryo Chronicles (litt gøy skal man ha,

5727 <p
>Vi må få leverandører av pedagogisk programvare med på laget, men
5728 også utvikle vår egen tilpasset det norske markedet. Det er også
5729 mulig å involvere utdanningssektoren direkte i arbeidet, for eksempel
5730 gjennom studentprosjekter der elevene selv er med å utforme
5731 programvare direkte eller indirekte gjennom aktive bidrag. Dette gjør
5732 ikke bare samarbeidet tettere, men fokuset på standarder og friheten
5733 til å velge sin egen løsning vil kanskje stimulere interessen for
5734 framtidig deltakelse i bransjen. Vi som driver med fri og åpen
5735 programvare ønsker oss ikke rene konsumenter, men tenkende og
5736 selvstendige individer som kan være med å skape sin egen fremtid.

>New in the Squeeze version of
5746 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> is the
5747 ability for clients to automatically configure their proxy settings
5748 based on their environment. We want all systems on the client to use
5749 the WPAD based proxy definition fetched from
<tt
>http://wpad/wpad.dat
</tt
>, to
5750 allow sites to control the proxy setting from a central place and make
5751 sure clients do not have hard coded proxy settings. The schools can
5752 change the global proxy setting by editing
5753 <tt
>tjener:/etc/debian-edu/www/wpad.dat
</tt
> and the change propagate
5754 to all Debian Edu clients in the network.
</p
>
5756 <p
>The problem is that some systems do not understand the WPAD system.
5757 In other words, how do one get from a WPAD file like this (this is a
5758 simple one, they can run arbitrary code):

5775 http_proxy=http://webcache:
3128/
5776 ftp_proxy=http://webcache:
3128/
5777 </pre
></blockquote
>
5779 <p
>To do this conversion I developed a perl script that will execute
5780 the javascript fragment in the WPAD file and return the proxy that
5782 <tt
><a href=
"http://www.debian.org/
">http://www.debian.org/
</a
></tt
>,
5783 and insert this extracted proxy URL in
<tt
>/etc/environment
</tt
> and
5784 <tt
>/etc/apt/apt.conf
</tt
>. The perl script wpad-extract work just
5785 fine in Squeeze, but in Wheezy the library it need to run the
5786 javascript code is
<a href=
"http://bugs.debian.org/
631045">no longer
5787 able to build
</a
> because the C library it depended on is now a C++
5788 library. I hope someone find a solution to that problem before Wheezy
5789 is frozen. An alternative would be for us to rewrite wpad-extract to
5790 use some other javascript library currently working in Wheezy, but no
5791 known alternative is known at the moment.
</p
>
5793 <p
>This automatic proxy system allow the roaming workstation (aka
5794 laptop) setup in Debian Edu/Squeeze to use the proxy when the laptop
5795 is connected to the backbone network in a Debian Edu setup, and to
5796 automatically use any proxy present and announced using the WPAD
5797 feature when it is connected to other networks. And if no proxy is
5798 announced, direct connections will be used instead.
</p
>
5800 <p
>Silently using a proxy announced on the network might be a privacy
5801 or security problem. But those controlling DHCP and DNS on a network
5802 could just as easily set up a transparent proxy, and force all HTTP
5803 and FTP connections to use a proxy anyway, so I consider that
5804 distinction to be academic. If you are afraid of using the wrong
5805 proxy, you should avoid connecting to the network in question in the
5806 first place. In Debian Edu, the proxy setup is updated using dhcp and
5807 ifupdown hooks, to make sure the configuration is updated every time
5808 the network setup changes.
</p

5810 <p
>The WPAD system is documented in a

5842 med brukte jeg først Mandrake og så Debian. Og siden jeg oppdaget at

5862 var noen annen løsning. «Vandrende arbeidsstasjon» mener jeg ikke
5863 fantes da. Dessuten ville jeg ha siste versjon, da den KDE-versjonen

5904 <description><p
>Since the Lenny version of
5905 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>, a
5906 feature to save power have been included. It is as simple as it is
5907 practical: Shut down unused clients at night, and turn them on again
5908 in the morning. This is done using the
5909 <a href=
"http://packages.qa.debian.org/s/shutdown-at-night.html
">shutdown-at-night
</a
> Debian package.
</p
>
5911 <p
>To enable this feature on a client, the machine need to be added to
5912 the netgroup shutdown-at-night-hosts. For Debian Edu, this is done in
5913 LDAP, and once this is in place, the machine in question will check
5914 every hour from
16:
00 until
06:
00 to see if the machine is unused, and
5915 shut it down if it is. If the hardware in question is supported by
5917 <a href=
"http://packages.qa.debian.org/n/nvram-wakeup.html
">nvram-wakeup
</a
>
5918 package, the BIOS is told to turn the machine back on around
07:
00 +-
5919 10 minutes. If this isn
't working, one can configure wake-on-lan to
5920 try to turn on the client. The wake-on-lan option is only documented
5921 and not enabled by default in Debian Edu.
</p
>
5923 <p
>It is important to not turn all machines on at once, as this can
5924 blow a fuse if several computers are connected to the same fuse like
5925 the common setup for a classroom. The nvram-wakeup method only work
5926 for machines with a functioning hardware/BIOS clock. I
've seen old
5927 machines where the BIOS battery were dead and the hardware clock were
5928 starting from
0 (or was it
1990?) every boot. If you have one of
5929 those, you have to turn on the computer manually.
</p
>
5931 <p
>The shutdown-at-night package is completely self contained, and can
5932 also be used outside the Debian Edu environment. For those without a
5933 central LDAP server with netgroups, one can instead touch the file
5934 <tt
>/etc/shutdown-at-night/shutdown-at-night
</tt
> to enable it.
5935 Perhaps you too can use it to save some power?

>I am happy to announce that finally we managed today to wrap up and
5945 publish the third beta version of
5946 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> based
5947 on Squeeze. If you want to test a LDAP backed Kerberos server with
5948 out of the box PXE configuration for running diskless machines and
5949 installing new machines, check it out. If you need a software
5950 solution for your school, check it out too. The full announcement is
5951 <a href=
"http://lists.debian.org/debian-edu-announce/
2012/
02/msg00000.html
">available
</a
>
5952 on the project announcement list.
</p
>
5954 <p
>I am very happy to report these changes and improvements since
5955 beta2 (there are more, see announcement for full list):
</p
>
5959 <li
>It is now possible to change the pre-configured IP subnet from
5960 10.0.0.0/
8 to something else by using the subnet-change tool after
5961 the installation.
</li
>
5963 <li
>Too full partitions are now automatically extended on the Main
5964 Server, based on the rules specified in /etc/fsautoresizetab.
</li
>
5966 <li
>The CUPS queues are now automatically flushed every night, and all
5967 disabled queues are restarted every hour. This should cut down on
5968 the amount of manual administration needed for printers.
</li
>
5970 <li
>The set of initial users have been changed. Now a personal user
5971 for the local system administrator is created during installation
5972 instead of the previously created localadmin and super-admin users,
5973 and this user is granted administrative privileges using group
5974 membership. This reduces the number of passwords one need to keep
5975 up to date on the system.
</li
>
5979 <p
>The new main server seem to work so well that I am testing it as my
5980 private DNS/LDAP/Kerberos/PXE/LTSP server at home. I will use it look
5981 for issues we could fix to polish Debian Edu even further before the
5982 final Squeeze release is published.
</p
>
5984 <p
>Next weekend the project organise a
5985 <a href=
"http://lists.debian.org/debian-edu-announce/

01/msg00001.html
">developer
5986 gathering

5987 version, and start initial planning for the Wheezy version. Perhaps I
5988 will see you there?

>With some computer hardware, one need non-free firmware blobs.
5998 This is the sad fact of todays computers. In the next version of
5999 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> based
6000 on Squeeze, we provide several scripts and modifications to make
6001 firmware blobs easier to handle. The common use case I run into is a
6002 laptop with a wireless network card requiring non-free firmware to
6003 work, but there are other use cases as well.
</p
>
6005 <p
>First and foremost, Debian Edu provide ISO images for DVD and CD
6006 with all firmware packages in the Debian sections main and non-free
6007 included, to ensure debian-installer find and can install all of them
6008 during installation. This take care firmware for network devices used
6009 by the installer when installing from from local media. But for
6010 example multimedia devices are not activated in the installer and are
6011 not taken care of by this.
</p
>
6013 <p
>For non-network devices, we provide the script
6014 <tt
>/usr/share/debian-edu-config/tools/auto-addfirmware
</tt
> which
6015 search through the
<tt
>dmesg
</tt
> output for drivers requesting extra
6016 firmware. The firmware file name is looked up in the Contents-ARCH.gz
6017 file available in the package repository, and the packages providing
6018 the requested firmware file(s) is installed. I have proposed to do
6019 something similar in debian-installer (BTS report
6020 <a href=
"http://bugs.debian.org/
655507">#
655507</a
>), to allow PXE
6021 installs of Debian to handle firmware installation better. Run the
6022 script as root from the command line to fetch and install the needed
6023 firmware packages.
</p
>
6025 <p
>Debian Edu provide PXE installation of Debian out of the box, and
6026 because some machines need firmware to get their network cards
6027 working, the installation initrd some times need extra firmware
6028 included to be able to install at all. To fill the PXE installation
6029 initrd with extra firmware, the
6030 <tt
>/usr/share/debian-edu-config/tools/pxe-addfirmware
</tt
> script is
6031 provided. Again, just run it as root on the command line to fill the
6032 PXE initrd with firmware packages.
</p
>
6034 <p
>Last, some LTSP clients might also need firmware to get their
6035 network cards working. For this,
6036 <tt
>/usr/share/debian-edu-config/tools/ltsp-addfirmware
</tt
> is
6037 provided to update the LTSP initrd with firmware blobs. It is used
6038 the same way as the other firmware related tools.
</p
>
6040 <p
>At the moment, we do not run any of these during installation. We
6041 do not know if this is acceptable for the local administrator to use
6042 non-free software, and it is their choice.

6061 språket melde seg til dyst. Det er mangel på nordsamiske oversettere

>I serien med intervjuer av folk i
6155 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet, har jeg nå
6156 lyktes med å få tak i en skolemann som ikke er aktiv med utviklingen,
6157 men likevel har vært med nesten siden starten av prosjektet. Jeg
6158 ønsker derfor velkommen til Paul Reidar Løsnesløkken, en mann med
6159 mange års erfaring i bruk av Skolelinux.
</p
>
6161 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
6163 <p
>Jeg driftet tidligere IKT løsningen for skolene i
6164 <a href=
"http://www.nord-odal.kommune.no/
">Nord-Odal
</a
>. I dag er jeg
6165 IKT-konsulent for hele kommunen og samarbeider med
6166 <a href=
"http://www.hedmarken-ikt.no/
">Hedmark-IKT
</a
> for best mulig
6167 tjenester til kommunen. Jeg har bakgrunn som elektronikkreparatør og
6168 grunnskolelærer og har tatt en del fag innen IKT, i hovedsak
6169 driftsfag. IKT i Nord-Odal kommune blir i dag driftet av Hedmark IKT
6170 som er et samarbeid mellom Løten, Stange, Grue, Hamar, Kongsvinger og
6171 Nord-Odal. Jeg er fortsatt
"IKT-personen
" på skolene i kommunen og
6172 følger opp og gjør enkelte mindre endringer der.
</p
>
6174 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
6176 <p
>Kommunen satset på Skolelinux i
2004. Jeg var ikke med i
6177 beslutningsprosessen den gang, men ble likevel med fra starten når
6178 dette ble levert.
</p
>
6180 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6182 <p
>Fordelene med Skolelinux er rask oppstart, sentral drift av
6183 klientene, klienter som jobber raskt og effektivt, bedre
6184 funksjonalitet på eldre utstyr og en ganske god programpakke med fri
6185 programvare som følger med. Løsningen med halvtykke klienter gjør at
6186 prosessering skjer lokalt med alltid ferske maskiner.
</p
>
6188 <p
>Skolelinux kan fungere godt på gammelt utstyr, men det er klart at
6189 utstyr også blir for gammelt selv for Skolelinux. I forbindelese med
6190 at vi nylig fikk nye servere og ny installasjon kastet jeg ut ca
60
6191 klienter som fortsatt var i drift etter at de var kjøpt godt brukt i
6192 2004. Noe var rundt
15 år gammelt, men var fortsatt i bruk. Noen
6193 klaget på at det nå gikk veldig tregt på en del pedagogiske nettsider
6194 med flash o.l. Det er fullt forståelig.
</p
>
6196 <p
>Jeg fikk nylig et spørsmål fra ungdomsskolens rektor om jeg kunne
6197 legge inn
<a href=
"http://freemind.sourceforge.net/
">FreeMind
</a
>, et
6198 tankekartprogram , på skolens elev-Windowsmaskiner. Lærerne hadde
6199 vært på kurs og ville ta dette i bruk. Skolen har ca halvparten av
6200 elevmaskinene på bærbare Windowsmaskiner. Da kunne jeg fortelle at
6201 dette programmet allerede lå inne på den nye Skolelinuxløsningen
6202 som nettopp var satt i drift, klart til bruk.
</p
>
6204 <p
>Vi har de bærbare maskinene på ungdomsskolen i domene med
6205 Skolelinux. Dette fungerer også meget bra nå. Elevene får opp en
6206 midlertidig windowsprofil når de logger på. Denne profilen slettes
6207 etter at de logger av, noe som medfører rene profiler hver gang de
6208 starter opp en maskin. De må lagre i sin Skolelinprofil, noe som
6209 medfører at de får tak i sine filer uavhengig av om de starter en
6210 Windowsmaskin eller en Skolelinuxklient. Det er mye mindre trafikk i
6211 det trådløse nettet etter at ikke hele profiler blir lastet opp til de
6212 enkelte Windowsmaskinene og tilbake når man avslutter. Jeg vet ikke om
6213 dette er standardoppsett i Skolelinux, men slik er vårt oppsett
6216 <p
>Vi har i flere år satt opp vår løsning slik at skriverkøer slettes
6217 og skrivere startes hver natt. Hyggelig å høre at dette nå skal bli
6218 en standard i Skolelinuxløsningen. Dette har vært en god hjelp for
6221 <p
>Elevene er lite opptatt av om de jobber på en Skolelinux eller en
6222 Windowsmaskin bare de har de programmene de trenger og at det virker
6223 når det skal brukes. Vi kjører mest mulig de samme programmene på
6224 Windows som i Skolelinux, som f.eks Audacity og LibreOffice.
</p
>
6226 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6228 <p
>Lærere bruker hos oss Windows. Dette fordi de da selv har mer
6229 kontroll over sin maskin, kan bruke den overalt, og kan legge inn
6230 programmer selv når de trenger noe i forhold til kurs o.l de er
6231 på. Jeg tror lærernes selvstendighet her gjør dem tryggere på IKT-bruk
6232 generelt. Det at de av og til får opp advarsler og lignende gjør også
6233 at de må tenke igjennom og spørre om ting rundt datasikkerhet.
</p
>
6235 <p
>Det er en del programmer vi bruker som ikke finnes for Linux. Mest
6236 brukt er nok Photostory3 som brukes i mange sammenhenger, særlig på
6237 ungdomsskolen, bl.a. til å lage herbarier (plantesamling) . Dette
6238 finnes gratis for Windows, men er ikke fri programvare. Vi er opptatt
6239 av at programmer elevene bruker på skolen også kan brukes gratis
6240 hjemme. Det er også en del programmer som brukes til spesielle elever
6241 som bare går i Windows. Det er viktig med fokus på funksjoner og ikke
6242 på hvilket OS man bruker.
</p
>
6244 <p
>For oss er det kombinasjonen mellom Skolelinux og Windows som gir
6245 oss en god og hel løsning. Skolelinux er best der de er gode.
</p
>
6247 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
6249 <p
>Selv er det LibreOffice jeg bruker til daglig. Jeg bruker selv en
6250 Windowsmaskin. Jeg har benyttet en del fri programvare i forbindelse
6251 med sjekking av trafikk i nettverk, slik som Wireshark, men dette er
6252 jo ikke aktuelt for skolene. Jeg er generelt glad i programmer som
6253 fungerer på både Linux og Windows og gjerne MAC.
</p
>
6255 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
6256 skoler til å ta i bruk fri programvare?
</strong
></p
>
6258 <p
>Det er viktig at det benyttes programmer som elevene også kan ta i
6259 bruk hjemme. Det skal da være enkelt, lovlig og gratis for
6260 elevene. Da er jeg ikke lenger veldig opptatt av om det kalles
"fri
6261 programvare
". For skolene tror jeg
"gratis
" og
"funksjonelt
" er bedre
6262 begreper enn
"fri
" i forhold til programmer. De fleste skiller nok
6263 ikke mellom
"fri
" og
"gratis
". Det er nå svært mange elever som
6264 benytter OpenOffice eller LibreOffice som sin primære kontorpakke

>During christmas, I have been working getting the next version of
6321 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> ready
6322 for release. The initial problem I looked at was particularly
6323 interesting.
</p
>
6325 <P
>The installer would hang at the end when it was doing it
6326 post-installation configuration, and whatevery I did to try to find
6327 the cause and fix it always worked while I tested it, but never when I
6328 integrated it into the installer and ran the installation from
6329 scratch. I would try to restart processes, close file descriptors,
6330 remove or create files, and the installer would always unblock and
6331 wrap up its tasks.
</p
>
6333 <p
>Eventually the cause was found. The kernel was simply running out
6334 of entropy, causing the Kerberos setup to hang waiting for more.
6335 Pressing keys was adding entropy to the kernel, and thus all my tries
6336 to fix the problem worked not because what I was typing to fix it, but
6337 because I was typing.
</P
>
6339 <p
>The fix I implemented was to add a background process looking at
6340 the level of entropy in the kernel (by checking
6341 /proc/sys/kernel/random/entropy_avail), and if it was too small, the
6342 installer will flush the kernel file buffers and do
'find /
' to
6343 generate some disk IO. Disk IO generate entropy in the kernel, and is
6344 one of the few things that can be initated from within the system to
6345 generate entropy.

6364 Denne gangen har jeg besøk av et avtroppende styremedlem i
6365 <a href=

</strong

>
6370 <p
>Jeg heter Peter Hansteen, og jobber til daglig som seniorkonsulent
6371 i EDB ErgoGroup i Bergen. I praksis betyr det systemadministrasjon på
6372 Unix (primært Solaris, men en viss komponent av Linux). Men Solaris
6373 er for meg et relativt nytt bekjentskap, hovedplattformen min har
6374 generelt vært OpenBSD og til dels FreeBSD.
</p

6376 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
6378 <p
>Jeg husker ikke helt alle detaljene mer ;) - men jeg tror det var
6379 gjennom news-gruppen no.it.os.unix.linux.diverse, efn-listen og
6380 etterhvert også BLUG-miljøet her i Bergen. Vi hadde et par
6381 Skolelinux-sentrerte BLUG-møter for noen år siden, og det har vært et
6382 par Skolelinux-utviklersamlinger her.
</p
>
6384 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6386 <p
>Jeg bruker dessverre ikke Skolelinux daglig. Men slik jeg kjenner
6387 prosjektet har det vært i stand til å ta opp i seg det beste av fri
6388 programvare i mange kategorier, så fra et sysadmin-perspektiv ser det
6389 ut som en svært behagelig sak. For brukerne er det vel både en fordel
6390 og en ulempe at det ikke er Windows. Men vi håper at fordelene med et
6391 fritt system etterhvert vil bli åpenbare for både elever, lærekrefter
6392 og foreldre.
</p
>
6394 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6396 <p
>Vel, ulempen er vel først og fremst at andre aktører med mer
6397 kapitalmuskel har klart å etablere seg som det både lærere og foreldre
6398 føler seg trygge på, selv om det etter mitt hode ikke er noen grunn
6399 til å være spesielt trygg på de kommersielle alternativene.
</p
>
6401 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
6403 <p
>Når jeg får bestemme helt selv, bruker jeg kun fri programvare. Da
6404 helst med vekt på ting som kjører greit på OpenBSD. Hjemme er det
6405 OpenBSD, Ubuntu eller FreeBSD vi bruker. På skrivebordet er det en
6406 avveining mellom Gnome, KDE eller hva-det-nå-heter som er
6407 standardvalget i Ubuntu, ellers er det de kjente tingene som
6408 LibreOffice, Emacs, mplayer. På server er det selvfølgelig Apache,
6409 for overvåking både OpenNMS og Nagios (det bare ble sånn, og
6410 forskjellige siter). Jeg skriver til tider om slikt jeg holder på med
6412 <a href=
"http://bsdly.blogspot.com
">http://bsdly.blogspot.com
</a
>.
</p
>
6414 <p
>Men vi må nevne at selv vi har en Microsoft-ting som vi slår på når
6415 vi av en eller annen grunn må. Det betyr igjen vanligvis når en
6416 mobiltelefon eller en annen lukket elektronisk dings krever kontakt
6417 via en slik for å få oppdateringene sine.
</p
>
6419 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
6420 skoler til å ta i bruk fri programvare?
</strong
></p
>
6422 <p
>Hadde vi hatt det rette svaret på det spørsmålet, så hadde vi
6423 gjerne hatt Skolelinux som førstevalg på alle skoler ;)
</p
>
6425 <p
>Men jeg tror vi må legge vekt på flere forskjellige ting. En helt
6426 sentral sak er å fokusere på fri programvare og åpne standarder som de
6427 demokratiske verdiene de faktisk er. Det har kanskje kommet litt for
6428 mye i bakgrunnen i forhold til strevet etter å lage det mest mulig
6429 'brukervennlige
' systemet. Det er en tung vei å gå, så det er
6430 forståelig at freenix-aktivister heller velger å skrive kode og annet
6431 som er mer lystbetont. Mer praktisk tror jeg vi må gjøre i alle fall
6432 to ting: For det første sørge for å fortsette med å levere det best
6433 mulige frie produktet, slik at det er lett å både komme i gang og
6434 holde systemene i daglig drift, og for det andre
2) spore opp mulige
6435 aktivister der de finnes, via lokale brukergrupper, sosiale medier
6436 eller annet og sørge for at de fortsetter å være aktive. Mer og
6437 mindre uformelle treff kan være nyttig i tillegg til de mer
6438 organiserte møtene med foredrag, konferanser og utviklersamlinger.

6463 <p

2000, og da spesielt med Linux. Dette var da et av
6464 de mest tydelige linux prosjektene i Norge, og her ønsket jeg å
6465 bidra. Var aktivt med i prosjektet i
4-
5 år.

>
6467 <p
><strong

6469 <p
>Fordelene slik jeg ser det er den sentraliserte driftmodellen, og
6470 alle de vel gjennomtenkte løsningene som er inkludert i denne
6471 løsningen. Samtidig er det basert på en stabil, og godt kjent
6472 plattform. Dette vil si at man har en løsning som skal være mye
6473 tilgjengelig, og hvor det er relativt enkelt å få tak i personer som
6474 kan mye om den grunnleggende plattformen.
</p
>
6476 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6478 <p
>De største utfordringene med en løsningen er at den er intensiv på f.eks
6479 nettverk. I seg selv ikke et problem for en enkelt skole, men skal løsningen
6480 kjøres i større skala, med sentraliserte servere, så gir dette noen
6481 utfordringer.
</p
>
6483 <p
>Utifra hva jeg har sett på større installasjoner så er det ikke så
6484 enkelt å skjønne, hva som bør gjøres for at den skal skaleres opp, og
6485 da ta godt vare på alle sider av dette, ikke bare mer server å fordele
6486 last/trykk, men hvordan også beholde robustheten og fleksibiliteten i
6487 løsningen.
</p
>
6489 <p
>En annen utfordring er at stadig flere produkter som skal brukes i
6490 skoleløsningen ikke er laget til å kunne brukes i en
6491 skolelinuxløsning. Det blir derfor fort mye skreddersøm i de
6492 forskjellige installasjonene, for å få diverse pedagogiske programmer,
6493 webløsninger, smartboards, m.m. til å fungere. Man er også en for
6494 liten kundebase til at leverandørene ønsker å gjøre noe med
6495 utfordringen. Problemet overlates til oss.
</p
>
6497 <p
>Det er også en kontinuerlig utfordring rundt problemet med å holde
6498 programvare på stabile versjoner, kontra å få ny funksjonalitet. Dette
6499 er jo en konflikt mellom oss som ønsker å drifte en stabil, og
6500 kostnadseffektiv løsning, mot sluttbrukerne som ønsker seg funksjoner
6501 det er vant med fra andre løsninger, eller som de må ha for at et
6502 eller annet nytt produkt skal fungere i løsningen. Dette er en
6503 utfordring også for andre plattformer.
</p
>
6505 <p
>En siste utfordring som ikke har noe med løsningen å gjøre, men med
6506 det omkringliggende miljøet denne skal kjøre i, er at de enhetene som
6507 skal drifte dataløsninger for kommuner og fylkeskommuner begynner å
6508 profesjonaliseres, og er da avhengig av å ha standard løsninger for å
6509 drifte store brukermasser. MS er selvsagt klar over dette, og har jo
6510 nå flere områder de begynner å bli veldig dominerende på. Den største,
6511 og mest problematiske er katalogtjenesten. Man får snart ikke tak i
6512 større løsninger som ikke krever en AD. Når man da har store enheter
6513 som drifter både kommunalt ansatte og skoler, så vil det være et
6514 stordriftargument å standardisere på en katalog tjeneste, og da har
6515 man ikke noe valg. Her er alle slike driftsenheter for små til å få
6516 gjort om på dette. Her burde konkurransemyndighetene kommet på
6517 banen. Men konkurransetilsynet i USA griper sjeldent (og ikke før det
6518 har gått veldig lang tid) inn i monopolsituasjoner så lenge
6519 monopolisten er et amerikansk firma, så da har vel ikke andre
6520 myndigheter så mye de skulle ha sagt....

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

</strong

6536 <p
>Det er et godt spørsmål, som jeg har lurt på selv.
</p
>
6538 <p
>Argumentene som ofte har vært brukt om at ting koster mindre holder
6539 ikke mål når man ser på hva som faktisk koster penger. Det er de
6540 ansatte som er en kostnadsdriver. Det vil si at hvis man har et system
6541 som den ansatte kan, så vil en kostnad på dette systemet kunne
6542 forsvares ganske mye ved at den ansatte gjør dette raskere og
6543 effektivt. Også uten å måtte eventuelt leie inn folk.
</p
>
6545 <p
>Jeg syns det er viktigere å fokusere på prinsippet med å velge fri
6546 programvare, men det er også et felt hvor man fort møter lite
6547 forståelse blant de ansatte i skolen.
</p
>
6549 <p
>Her må nok strategien fortsette å være at de sentrale myndighetene
6550 må sende tydelige signaler for hva de ønsker at offentlige enheter
6551 skal gjøre. Det var mye positivt på gang ang. dette for et par år
6552 siden. Både med eNorge og eKommune planene, men dette syns jeg har
6553 stoppet opp. En del av dette kan jo kanskje være usikkerheten som
6554 etter hvert har blitt, når man har sett kompleksiteten i de
6555 prosjektene som har blitt igangsatt. Det har også blitt noe usikkerhet
6556 i markedet ref. Sun, Oracle, Novell, Microsoft m.m. Samtidig har jo
6557 også de proprietære programleverandørene sørget for å endre sine
6558 lisenser slik at man uansett ikke slipper unna kostnaden til deres
6559 produkter, selv om man skulle velge alternativer. Da er det økonomiske
6560 argumentet, som jeg nevnte tidligere, spilt ganske godt ut over
6561 sidelinjen.

6585 hadde vel hørt om prosjektet i media før en gjeng i Trondheim startet
6586 opp SPIST, Skolelinux-prosjektet i Sør-Trøndelag, hvor vi hjalp noen
6587 skoler i nærområdet med å installere Skolelinux og finne brukt
6588 IT-utstyr til disse. Det var moro å gjøre noe praktisk for å spre
6589 Skolelinux, og å se hvor fort gjort det var å sette opp utrangerte
6590 klientmaskiner og få disse opp som tynnklienter på helt nye datasaler
6591 på skolene, kun med kostnaden til servere.

6595 <p
>Det er et system spesielt skreddersydd for drift av et stort antall

6597 er enkelt og billig å installere og drifte, og det trenger ikke ny
6598 maskinvare for god ytelse.

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

6613 Telefonen min er en Android, og der bruker jeg programmene K-

6614 OI Shopping list, Shuffle, ZXing, OI Notepad og ADW Desktop. På jobb
6615 bruker jeg JBoss, Eclipse, uCLinux for Blackfin, RCF-CPP, Qt, Maven,

>En bør fokusere på totalkostnader inkludert driftsbehov,
6622 fleksibilitet, åpenhet og ikke låsing til en leverandør framfor sparte
6623 lisenskostnader, samt programvarens kvalitet og fortrinn, og at den
6624 fritt kan brukes på et ubegrenset antall PC-er, også hjemme hos
6625 elevene. En bør også forbedre den fri programvaren ved testing,
6626 bugrapportering og kodebidrag om man kan, og ikke anbefale programvare
6627 uten at man har forsikret seg at den har tilstrekkelig kvalitet,
6628 ellers kan man lett oppnå det motsatte. Tror en bør selge inn
6629 konseptet til fylkes-/statsnivå, kanskje med bidrag til
6630 utviklingsarbeid fra disse som alle landets skoler kan få glede

>Mine bloggposter om Linux i skolene i Norge førte til at inspektør
6641 og ildsjel på Harestad skole tok kontakt og fortalte at de bruker
6642 Linux på sin skole, og lurte på om de kunne bidra til å gjøre
6643 fordelene kjent. Riktig nok bruker de ikke
6644 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
> på denne skolen,
6645 men jeg synes dette er en god anledning til å gjøre flere fasetter
6646 rundt Linux-økosystemet kjent, og tok et lite intervju.
</p
>
6648 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p

6650 <p
>Mitt navn er Odin Hetland Nøsen og er en
70-modell. Jeg er bosatt i
6651 Stavanger og jobber nå på
9. året som undervisninginspektør på
6652 Harestad skole i Randaberg kommune (nabokommune til Stavanger).
</p
>
6654 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
6656 <p
>I
2002 begynte daværende IKT-ansvarlige og jeg et arbeid på skolen
6657 med å gå over fra Win98 til... noe annet. Vi testet en rekke
6658 forskjellige løsninger, deriblant Skolelinux, men endte opp med
6659 RedHat. Skolelinux var den gang ikke modent for det vi ville ha. Jeg
6660 har siden fulgt jevnlig med på hva skolelinux holder på med, men har
6661 hele tiden vært bedre fornøyd med vår egen
"standardiserte
" løsning på
6662 RedHat/CentOS og Fedora. Vi snuser for tiden på Ubuntu som løsning på
6663 klientsiden.
</p
>
6665 <p
>I dag har vi på skolen vår en større linux-løsning med
400 klienter
6666 som kjører en blanding av LTSP (tynnklient) og DRBL (tykk klient uten
6667 harddisk) med en masse tjenere på serverrommet. Vi drifter hele
6668 sulamitten selv med webtjener, eposttjener, webmail, filtjenere,
6669 virtuelle tjenere osv. Og IT-ansvarlig har en
80% stilling som
6670 IT-ansvarlig - og så er han KoH-lærer i de resterende
20% :-)
</p
>
6672 <p
>Du kan få en ide om hva vi holder på med om du går inn på
6673 <a href=
"http://www.gnuskole.no/
">http://www.gnuskole.no/
</a
>.
</p
>
6675 <p
>For å ta brodden av frykten for at ildsjeler gjør skolen sårbar om
6676 ildsjelene falle fra, har jeg forsikret kommunen og skolesjefen i
6677 Randaberg om at det finnes godt kommersielle tjenester vi kan benytte
6678 oss av - om det skulle bli nødvendig. Vi er tre stykker i kommunen som
6679 nå har
<strong
>god
</strong
> linux-kompetanse ift. å drifte et større
6680 system. IT-avdelingen i kommunen vil ikke ta på oss med ildtang -
6681 selv om vi nok har større IT-kompetanse mot linux enn det de selv har
6682 mot windows (de kjøper en
<strong
>masse
</strong
> konsulenttjenester
6683 fra ErgoGroup).
</p
>
6685 <p
>I kvantitet er Harestad og Grødem skole tilsammen et større
6686 IT-system enn resten av Randaberg kommune + Kvitsøy og Rennesøy, som
6687 kommunen også har driftsansvar for. Vi har som sagt rundt
800
6688 maskiner, mens kommunen med sitt driftsansvar har ansvar for rundt
500
6689 maskiner. Det er selvfølgelig litt forskjell i hvor kritiske
6690 tjenestene våre er, men det gir allikevel et litt rart bilde når
6691 IT-avdelingen overhode ikke er interessert i å snakke med oss om
6692 hvordan vi gjør ting :-)
</p
>
6694 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6696 <p
>Fra linux-perspektivet (ikke bare Skolelinux) er det en fordel av
6697 systemet er basert på fri programvare - og dermed fritt i ordets mange
6698 betydninger. Det er alt vi trenger: stabilt, relativt enkelt å drifte
6699 (tross alt - et større windowssystem er ikke enkelt å holde live det
6700 heller), rimelig i innkjøp og drift, og sist, men ikke minst, det er
6701 moderne for sluttbruker! Linux, i sine mange varianter,
6702 <strong
>ser
</strong
> nytt ut, fordi det hele tiden blir
6703 oppdatert. Derfor lever systemet opp til hvordan elever forventer at
6704 et moderne GUI skal være (i motsetning til WinXP :-).
</p
>
6706 <p
>Vi var veldig pragmatiske da vi begynte med linux i skolen. Det var
6707 billig, det fungerte og kunne bruke alle de gamle windows-maskinene
6708 som
"nye
" tynne klienter. I dag er vi mer bevisste fri
6709 programvare-tilhengere. Vi har oppdaget hva det er - og vi liker
6712 <p
>En av de
<strong
>store
</strong
> fordelene med fri programvare er at
6713 vi kan installere tjenester vi ønsker å tilby brukerne våre - uten å
6714 måtte tenke på om vi har råd til lisensene (fordi det er ingen). Alt
6715 vi setter i produksjon er ut i fra brukernes behov og vår kapasitet
6716 til å drifte dem. Vi skreddersyr tjenestene etter behovet og dermed
6717 trenger vi ikke ende opp med å kjøpe en pakke der vi egentlig bare var
6718 interessert i en liten del av den.
</p
>
6720 <p
>Bruk av linux frigjør ikke økonomiske midler, fordi midlene til IKT
6721 i skole er for få i utgangspunktet - men vi får så
6722 <strong
>mye
</strong
> mer igjen for dem når vi bruker en linux-løsning
6723 fremfor en windows-løsning. I praksis ser vi at vi måtte ut med det
6724 dobbelte på budsjettet vårt om vi skulle hatt en tilsvarende
6725 windows-løsning, som det vi i dag drifter med linux.
</p
>
6727 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6729 <p
>Ikke all pedagogisk programvare er tilgjengelig. Det er en del
6730 programvare i skolen som er laget med utviklerverktøy som bare virker
6731 i windows, f.eks. Drillpro, LingDys/LingWrite. Det er også
6732 "programmer
" som bare virker om du har tilgang til Microsoft Office,
6733 f.eks. AskiRaski.
</p
>
6735 <p
>Vi sliter også litt med at video-codecer ikke alltid er like lett å
6736 få opp å gå på klientene. Det er alltid en eller annen videosnutt fra
6737 nrk.no som ikke er så samarbeidsvillig, uansett mediaplayer.
</p
>
6739 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
6741 <p
>Alt :-) På skolen bruker vi det som finnes og som er nyttig. Det vi
6742 bruker mest er Firefox (jobber med Chrome, fordi det er
6743 <strong
>mye
</strong
> raskere med Flash enn Firefox), OpenOffice (skal
6744 over til LibreOffice), GIMP osv. Standardpakken av
6745 sluttbrukerprogrammer.
</p
>
6747 <p
>På tjenernivå bruker vi OpenWebMail (skal over til Zimbra), Exim
6750 <p
>Personlig bruker jeg de fleste programmer over flere plattformer,
6751 men jeg har lagt meg til en vane å prioritere bruken av fri
6752 programvare også i Windows
7 og OSX.

>
6754 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
6755 skoler til å ta i bruk fri programvare?
</strong
></p
>
6757 <p
>Jeg er langt i fra sikker. For det første handler det mye om at
6758 IKT-avdelingen i kommunen ofte er de som styrer hva som er IKT på
6759 skolene - og de liker å bruke avtalene med Microsoft, som de garantert
6760 har fra før. Dessuten - Select
6-avtalen til skolene gjør Microsoft
6761 skvettbillig.
</p
>
6763 <p
>Vi la vekt på effektiv drift av systemet - og at vi kunne øke
6764 antall maskiner uten å måtte øke budsjett for utstyr eller personell
6765 særlig mye, enn om vi hadde gått for en Microsoft-løsning. I praksis
6766 ser vi at en ren linux-installasjon driftes til halve prisen av en
6767 Microsoft-løsning.
</p
>
6769 <p
>Vi har i praksis også sett at det lærerne (og elevene) liker er at
6770 vi tilbyr
<strong
>veldig
</strong
> mange tjenester som ikke er så
6771 vanlige i en Microsoft-løsning. Det er ikke så vanlig at
6772 <strong
>elevene
</strong
> også har epost, hjemmekontor osv. Det har vi
6773 også brukt som et vellykket argument mot Microsoft.
</p
>
6775 <p
>Den beste måten er selvfølgelig at noen bare bestemmer
6776 det. Problemet er å få dem som har makt til å bestemme det til faktisk
6777 å gjøre det ;-)

>Fri programvare bygges sten for sten i det åpne, slik at koden og
6887 prosessen den lages på kan gjennomskues av andre enn de som har laget
6888 det. Det er et vitenskapelig og gjennomsiktig måte å lage programvare
6891 <p
>Skoler i vårt samfunn skal være steder hvor vitenskapelig kunnskap
6892 deles til alle. I dag har vi ikke et vitenskapelig tilnærming til
6893 hvordan programvaren som brukes på skolen lages. Skolelinux bringer
6894 inn at slik tilnærming i skoleverkets klasserom, siden
6895 operativsystemet er en åpent platform som gir skolene muligheten til å
6896 dra nytte av programvare som er laget av tusenvis av mennesker verden
6897 rundt og som gir elevene så vel som lærerne muligheten til å bruke,
6898 dele, forandre og forbedre OSet sitt uten begrensninger. I den
6899 forbindelsen representerer Skolelinux også konkrete resultater utfra
6900 samhandling på tvers av grenser.

6902 <p
>Når det gjelder de tekniske fordelene av Skolelinux er jeg sikker
6903 på at andre enn meg har allerede beskrevet disse bedre enn det jeg
6904 kan. Men jeg kan likevel tilføye noe: Skolelinux som sådan er en
6905 community-drevet operativsystemplatform. Som i ethvert
6906 community-prosjekt har alle Skolelinux brukere muligheten til å
6907 påvirke retning av prosjektet og resultatet som gjenspeiles i
6908 programvaren. Dette kommer sjeldent frem og jeg mener at det er noe
6909 som burde fokuseres mer på.

6972 <p
>Jeg husker en leverandør av et stort OS for noen år siden mente at

6974 kunne ta dette i bruk. Heldigvis er kunnskapen større nå og
6975 skikkelige

6985 <p
>Det største hinderet er det vi opplever på andre områder rundt
6986 fri programvare, nemlig kunnskap. For mange er det trygt å velge det vi
6987 alltid har valgt. Fordi leverandørene rundt oss sitter på den kunnskapen og
6988 de vi støtter oss på har den samme. Hvis vi klarer å riste løs litt og
6989 glemme gamle kriger mellom operativsystemer og leverandører, men sette ned
6990 hva som er viktig og velge ut fra det, så hadde man kanskje kommet ut med
6991 litt andre resultat. Jeg tror IT-folk er konservative og velger tradisjonelt
6992 og det er synd.

6999 skyen og setter pris på alt jeg slipper egen klient til. Derfor er
7000 jeg veldig sjarmert av små kjappe operativsystemer som krever minimalt
7001 av maskinvaren.

>Sturle Sunde, ansvarleg for skulenettet i Flora kommune. Eg driv,
7028 vidareutviklar og er andrelinje brukarstøtte for datanettet ved
7029 skulane i Flora kommune.
10 skular og meir enn
700 maskiner med
7030 Linux, medrekna tynnklientar. Tidlegare jobba eg i mange år med
7031 unix-drift ved Universitetets senter for informasjonsteknologi ved
7032 Universitetet i Oslo.

7034 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p

7036 <p
>Det er vanskeleg å svare konkret på. Eg har drive med Unix og Linux i
7037 alle år, og Skulelinux er eit godt kjent prosjekt i miljøet. Det var
7038 først i
2008, då eg tok til i min noverande jobb, at eg fekk bruk for
7039 Skulelinux for alvor.
</p
>
7041 <p
>Jobben min skulle vere drift av eit nytt skulenett i Flora kommune,
7042 levert av eit firma eg ikkje vil reklamere for. Systemet skulle vere
7043 ferdig levert i september året før. Dette viste seg å ta mykje lenger
7044 tid, og i haustferien
2008 hadde dei endå ikkje klart å få opp ei
7045 fungerande løysing. Situasjonen var prekær for den største skulen i
7046 kommunen med meir enn
500 elevar på ungdomssteget. Skulen hadde brukt
7047 Skulelinux før, og var tilfredse med det. No hadde dei vore utan
7048 fungerande datasystem i nesten eit år. Difor fekk eg opp ein ny tenar
7049 utanfor prosjektet og installerte Skulelinux på den. Etter litt
7050 justering av konfigurasjonen med god hjelp av #skolelinux på IRC, var
7051 den nye tenaren oppe og gjekk med både tynne og halv-tjukke klientar.
7052 Autentisering gjekk mot det nye systemet, slik at elevar og lærarar
7053 framleis har same brukarnamn og passord over alt. Dette berre
7054 fungerte, og vi bestemte oss for å erstatte delar av løysinga vi
7055 skulle få levert med Skulelinux.
</p
>
7057 <p
>Det høyrer med til historia at det nye systemet eg skulle drive frå
7058 januar
2008 endå ikkje er ferdig levert. Dei jobbar med saka, seier
7059 dei, og har von om å fullføre leveransen i løpet av
2011.
</p
>
7061 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
7063 <p
>Det er veldig mange. Eg skal ta nokre få.
</p
>
7065 <p
>Den viktigaste fordelen er at det igrunn berre er ei maskin å passe
7066 på, og det er tenaren. Med andre løysingar har ein gjerne programvare
7067 og anna som skal vedlikehaldast på kvar enkelt maskin. Med Skulelinux
7068 kan alle feil rettast og alle program oppgraderast på alle maskiner
7069 samstundes ved å gjere endringa som må til på tenaren. Eg kan sitje
7070 på kontoret og passe på alle tenarane i kommunen derifrå.
</p
>
7074 <li
>Tynne klientar gjer det mogleg å bruke eldre utstyr lenge, so lenge
7075 tenaren er sterk nok. Ein liten tenar med eit par halv-moderne CPUar
7076 og
2 GiB RAM held lenge for eit typisk klasserom med
30 tynnklientar,
7077 og det er lett å utvide med fleire.
7079 <li
>Halvtjukke klientar gjer det mogleg å utnytte kapasiteten i litt
7080 nyare maskiner betre, og avlaste tenaren. Ingenting vert installert
7081 lokalt på desse heller, og harddisken kan gjerne koblast frå. Gode
7082 halvtjukke klientar kan kjøpast brukt for under
1000-lappen, og det er
7083 heile kostnaden. Ingen lisensar eller anna på toppen, og det er ikkje
7084 krav til kraftigare tenar heller.
7086 <li
>Det er Linux. Vi har ikkje noko kluss med drivarar, dei berre er
7087 der. Heller ikkje med virus, dei finst i realiteten ikkje. Eller med
7088 elevar som klussar med installert programvare, for dei klarar ikkje å
7089 øydeleggje for nokon andre enn seg sjølve.
7093 <p
>Skulelinux er lagt opp til å vere veldig lett å installere rett ut
7094 av boksen på ein heil skule av ein interessert lærar. Det er ofte ei
7095 god løysing for skulen. Å ha nokon til stades som kjenner systemet og
7096 kan forklare enkle ting eller løyse problem der og då, er uvurderleg
7097 viktig for ein stressa lærar fem minutt før det ringer inn.

7099 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong

7101 <p
>All den ferdige konfigurasjonen gjer det tungvint å tilpasse
7102 Skulelinux til eit system som skal fungere saman med mange andre
7103 installasjonar i eit felles datanett for skulane i ein kommune. Det
7104 heile er prekonfigurert for ein skule, og utviding til mange skular
7105 med eigne tenarar er ikkje berre enkelt.

</strong

7109 <p
>Eg brukar mest alle små hjelpeprogram som føl med operativsystemet,
7110 samt scriptspråket perl. Elles er Firefox/Iceweasel, Gnome-terminal
7111 og ssh i kontinuerleg bruk. Av Linux-distribusjonar brukar eg både
7112 Debian, Ubuntu, SuSE og RedHat dagleg. Eg prøvar å finne det verktyet
7113 som passar best til kvar del av jobben.

7118 <p
>Det er to målgrupper ein må sikte mot. Det eine er alle skulane som
7119 manglar eller har eit lite tilfredsstillande opplegg i dag, og ikkje
7120 har råd til å kjøpe noko nytt og blankpussa opplegg. Der er det om å
7121 gjere å gjere det enkelt for skulane å finne Skulelinux, og gjere det
7122 enkelt for dei å få hjelp til installasjon på skulen. Gjerne med
7123 lokale kontaktpersonar. Her er det dugnadsinnsats som må til, for
7124 desse skulane har ikkje råd til å betale for dette.
</p
>
7126 <p
>Den andre og kanskje viktigare målgruppa er dei meir eller mindre
7127 profesjonelle kundane. Alle store offentlege innkjøp, inkludert
7128 innkjøp av nytt datasystem for skular, må ut på offentleg anbod.
7129 Offentlege anbod er mykje meir lukka enn dei gjev inntrykk av, og både
7130 regelboka og boka med triks for å sminke tilbodet er tjukk. Det er
7131 vanskeleg å komme inn utan eit solid salsapparat i ryggen. Kanskje
7132 Skulelinux skulle prøve aktivt å få seg eit partnarskap med eit av dei
7133 store som gjerne vil sterkare inn på den offentlege IT-marknaden?
7134 Nokon som kjenner triksa og har krefter til å ta opp kampen mot både
7135 dårlege anbod og Rudolf Blostrupmoen IT AS. Leveranse til skulane i
7136 ein kommune er ein god måte å få ein fot inn døra som leverandør til
7137 ein lukrativ kommunemarknad som kjøper alle tenester. Ta kontakt med
7138 nokon som er passeleg store og ikkje er Microsoft-partnar, og fortell:
7139 «Vi har eit ferdig produkt som du kan selje. Nei vi skal ikkje ha for
7140 det. Du kan gjerne gjere kva du vil med det, berre vi får lov til å
7141 hjelpe deg. Målgruppa er alle kommunar, og det er noko dei vil ha.
7142 Det er eit godt produkt, brukt av mange og godt likt.»

2010. Nå har jeg fått ny arbeidsplass og er
7162 40% lærer og
60% IKT med Windows XP, Win2003 server og et regionalt
7163 IKT-regime som legger premissene og begrensingene for hva vi kan gjøre
7164 på skolen.

7168 <p
>Jeg leste en artikkel om en dugnadsinstallasjon av Skolelinux på en
7169 skole på Jæren et sted. Tanken om dugnad og frihet appellerte til
7170 meg. Da vi skulle bygge ny skole var det en del vi måtte spare på,
7171 fordi vi beveget oss mot en kostnadssprekk. Kabling og investering i
7172 PC-er var en av tingene vi sparte på. Derfor kjøpe vi
72 pc-er for
390
7173 pr stk. En filtjener og en applikasjonsserver.

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

7177 <p
>Fordelen er at så mye er satt opp fra starten. I tillegg er det
7178 tydelig at pakka er laga for skoleverket. Brukerne har egne
7179 skrivebord, tilgang på mange gode verktøyprogrammer. Vi slipper å
7180 tenke på virus. Brukerne har ikke mulighet til å ødelegge
7181 klientoppsett, men har gode muligheter til å endre eget oppsett. Dette
7182 tror jeg er inspirerende og kjekt for mange brukere. Mappestrukturen
7183 er ferdig og det er
"enkelt
" å designe lokale mappestrukturer via
7184 skeleton. Noen av oss i skoleverket mener skolen skal være en
7185 "mot-kultur
". Da er Skolelinux et av valgene man kan ta. Et annet er å
7186 spise på indisk restaurant i stedet for Mc Donald
's når vi er på bytur
7187 osv.. Ordene deling, frihet, dugnad osv er positive ord i
7188 skoleverket. Det er viktig at elevene blir bevisst dette.

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

7192 <p
>Kompabiliteten er selvsagt et problem, selv om det er mindre nå enn
7193 før. For IKT-personer på skolene som skal drifte dette er det
7194 problematisk med kommandoer i terminalen. I tillegg er det alt for
7195 mange programmer i Skolelinux som ikke blir brukt. Jeg tror
7196 Skolelinux er tjent med å tone ned begrepet pedagogisk programvare.
7197 Slik jeg ser det finnes ikke denne kategorien programmer lengre slik
7198 de gjorde før, som frittsående programmer som installeres på en
7199 datamaskin eller på serveren. Det finnes en del spesialpedagogiske
7200 programmer, som Textpilot, LingDys, LingRight, AskiRaski, Ny i Norge
7201 osv. Men dette er programmer for enkelt-elever eller små grupper av
7202 elever. Det som bør være fokus er at alle undervisningsressurser som
7203 lages for nettet skal være nettleseruavhengig.

7207 <p
>OpenOffice bruker jeg til vanlig kontorarbeide. VLC bruker jeg som
7208 videoavspiller og av og til streaming av film. Gimp bruker jeg i
7209 undervisningen til bildemanipulering. Firefox og Chrome er mine
7210 favoritt-nettlesere. Firefox har lenge vært førstevalget mitt, nå
7211 bruker jeg mest Chrome. Opplever den som raskere og smidigere enn
7212 Firefox. Ubuntu bruker jeg som dualboot på jobb-maskinen min i
7213 tillegg til at alle PCer hjemme har en eller annen Ubuntu-distribusjon
7214 installert. Jeg bruker Clonezilla på Ubuntu
10.04 til kloning av
7215 datamaskiner på jobb. Det er selvsagt en haug andre frie programmer
7216 jeg bruker men jeg bruker dem ikke daglig. Jeg kan ramse opp:
7217 recordmydesktop, cinelerra, acidrip, soundjuicer, audacity, NX
7218 (no-machine), Kino, Rythmbox...

>Hvilken strategi tror du er den rette å bruke for å få
7221 skoler til å ta i bruk fri programvare?
</strong
></p
>
7223 <p
>Jeg tror oppsøkende virksomhet er den rette strategien.
7224 Ressurspersoner gjør avtaler med rådmenn, skolesjefer, rektorer. Det
7225 er slik konkurrentene gjør det. Fokuset i slike samtaler bør være
7226 kost-nytte. Dersom personer med økonomisk ansvar ser at de kan få
7227 like godt tilbud til mindre utgifter, tror jeg det er mulighet til å
7228 få innpass. Dersom de også kan få konkrete tilbud på drift i slike
7229 samtaler, vil de kanskje bli litt mer interesserte i hvor mye penger
7230 som faktisk går til IKT i skolene. Det er også viktig at vi ikke
7231 firer for mye på krav til datamaskiner. Det er flott at Skolelinux
7232 går på
"utrangert
" utstyr, men dette bør bare presenteres som et
7233 alternativ. Skolelinux-installasjoner med utrangert utstyr er ikke å
7234 foretrekke dersom man kan unngå det. Det skaper ikke entusiasme hos
7235 brukerne (elever og lærere) når de bruker gamle datamaskiner som går
7236 tregt. Det er kjempefint med skoler som har kommet seg frem til
7237 Skolelinux og fri programvare av seg selv, men de lever på nåde.
7238 Slike valg må fundamenteres hos skoleeier.

7252 gang er det en av folkene som har vært med lenge og som har tatt i
7253 bruk Skolelinux på alle skolene i Narvik kommune som skal i ilden.

7260 <p
>Mitt navn er Viggo Fedreheim, og jeg er pedagogisk og teknisk
7261 IKT-veileder for alle skoler i Narvik kommune. Jeg drifter totalt
17
7262 servere basert på Skolelinux og Debian. Jeg holder i tillegg noen kurs
7263 mellom all driftingen. For tiden arbeider jeg med en sentral
7264 LDAP-tjener for alle skoleservere samt våre Moodle- og
7265 Joomla-installasjoner.

7269 <p
>Gjennom en eller annen nettavis i
2001 der var det skrevet om
7270 Skolelinux. Artikkelen ga meg lyst til å prøve ut systemet.
</p
>
7272 <p
>Det startet i
2002 ved at jeg installerte en av de første utgavene
7273 av Skolelinux på en standard pc på Solneset skole i Tromsø. Denne var
7274 oppe fram til desember
2003 da jeg sluttet på den skolen og begynte i
7275 ny jobb i Narvik kommune.
</p

7277 <p
> I Narvik kommune var det i
2004 kun
2 servere på da totalt
15
7278 skoler. Disse var Windows NT baserte. På disse to skolene var det lite
7279 med maskiner. Jobben med å få Narvik Kommune opp på akseptabelt nivå
7280 virket å være formidabel. Men med hjelp av gode kollegaer og leder
7281 skrev jeg en IKT plan for Narvik kommune som ble vedtatt av politikere
7282 i august
2004. I denne planen ble det bestemt at Narvik kommune skulle
7283 bruke Skolelinux. Her ble det også satt av midler til kabling av god
7284 infrastruktur på alle skoler samt innkjøp av nye datamaskiner. Så i
7285 dag har vi
17 servere hvorav
13 er på Skolelinux, med ca
1500 klienter
7286 basert på tynne,
"halvtykke
" og et stort antall bærbare pcer basert på

7303 <p

7304 nettbaserte programmer istedet for å installere lokalt. Dette med
7305 enkelte leverandører som ikke kan levere programmer til Linux er et
7306 lite problem og over tid tror jeg at denne barrieren er borte.

7346 hvor jeg er på et Vegmeldings-prosjekt for Statens Vegvesen. På
7347 fritiden er jeg styreleder i FRISK (Fri programvare i skolen) og
7348 bidrar til bl.a. Skolelinux-prosjektet når jeg får tid til det. Det er

7356 <p
>Jeg var på en presentasjon av prosjektet i regi av Knut Yrvin på
7357 Gløshaugen i Trondheim, hvor jeg fattet stor interesse for prosjektet
7358 og ville hjelpe til så godt jeg kunne. Dette var vel i
2002 eller
7361 <p
>Jeg hadde fra før hørt om prosjektet fra før og syntes tanken bak var
7362 ganske fin, men hadde ikke noen interesse av bruke min egen fritid på
7365 <p
>I etterkant av presentasjonen startet jeg og noen andre fra
7366 Trondheim
"Skolelinux-prosjektet i Sør-Trøndelag
" . Hvor vi var med å
7367 bidra til at Trondheim kommune satte igang Selsbakk ungdomskole som et
7368 pilotprosjekt med Skolelinux, som egentlig var og er en stor suksess,
7369 men det virker ut som det ikke skjer noe mer på. I tillegg var vi med
7370 på dugnad på Brundalen videregående skole hvor vi installerte
7371 Skolelinux som såvidt jeg vet fortsatt kjører på Skolelinux.

7375 <p
>Det bygger på fri programvare og har lav kostnad i forhold til
7376 nytteverdien. Dette fordi det har forholdsvis lav inngangsum og bruker
7377 en arkitektur med sentral-drift som gir mange driftfordeler. I
7378 tillegg vil det kunne frigjøre kostnader for skolene slik at de kan
7379 bruke dem til å ansette f,eks flere lærere om det er ønskelig.

7388 <p
>Til utvikling av Java-applikasjoner og Android bruker jeg Eclipse og
7389 Quanta til web-utvikling via php. For all bildebehandling bruker jeg
7390 GIMP og Blender til
3d-modellering . Dessverre har Blender en bratt
7391 læringskurve i starten, men det er absolutt verdt det.
7393 <p
>Til musikk bruker jeg stort Rhytmbox. Firefox til surfing på nettet og
7394 Thunderbird og Evolution til e-post,
7396 <p
>På database-siden bruker jeg PostgreSQL, Postgis og av og til Mysql.
7398 <p
>Når jeg får tid til å spille bruker jeg som regel et strategi-spill
7399 som er basert på TA Spring-motoren (springrts.com), her er det et
7400 veldig bra utvalg av gratis spill som er av høy kvalitet. Veldig lett

7421 <p
>Kommunen min har to omtrent jevnstore tettsteder, og en
7422 ungdomsskole i hvert av tettstedene. Den minste av disse har ca
300
7423 elever og til denne sogner det
3 barneskoler. Den største har ca
350
7424 elever og til denne sogner det
4 barneskoler.
</p
>
7428 <li
>Kommunen har i veldig lang tid forsømt IKT i skolen, og det har
7429 bare blitt gitt smuler i ny og ne. Det er kun den største av
7430 ungdomsskolene som har hatt en skikkelig datapark, og dette takket
7431 være en naturfaglærer som ble lei av å vente på kommunen. Det gjorde
7432 at vi bestemte oss for å ta ting i egne hender, og da vha
7433 skolelinux. En testinstallasjon med
10 gamle PCer ble gjort, og vi så
7434 raskt at dette var veldig lovende. Neste etappe var å gi alle lærere
7435 egen PC på arbeidsplassene sine (
2004), og så sette opp
16 PCer på to
7436 datarom. Vi har kun basert oss på å kjøpe inn brukte maskiner, og
7437 aldri dyrere enn
1000 kr pr klient. For to år siden så hadde vi
7438 klienter i alle klasserom, og totalt hadde vi da rundt
250 stk. Rundt
7439 40 klienter brukes av lærerne og kjører på en egen server. Elvene har
7440 resten, og kjører også en egen server. Servere har vi også kjøpt
7441 brukt,
2 år gamle servere koster
6-
7000 kroner.
</li
>
7443 <li
>Skolen vår er et relativt gammelt bygg, men en meget dyktig
7444 vaktmester har sammen med IKT-ansvarlig/Naturfaglærer lagt kabler til alle
7445 rom. Gradvis har vi byttet ut billige svitsjer med mer solide saker
7446 som er mulig å fjernstyre.
</li
>
7448 <li
>Vi har i all hovedsak greid å få dette til over eget budsjett, men
7449 vi har også passet på å få penger når de andre skolene har fått
7450 bærbare PCer til lærere osv.
</li
>
7452 <li
>Vår IKT-ansvarlig har gjort (og gjør) en fenomenal jobb, og vi har
7453 en maskinpark som de andre av kommunens skoler bare kan drømme
7458 <p
>Så skjer det som ofte skjer. Det kommer en eller annen
7459 selger/blåruss og skal fikse ALT. I vårt tilfelle betyr dette også
7460 sentralisering av drift. Den ny-ansatte på kommunens IT-avdelingen
7461 skal også ha jobb, og ser for seg å ta over skoledriften. Kommunen
7462 kjøper inn eksterne driftstjenester, og nekter i samme slengen å ta
7463 hensyn til skolen vår. Dette til tross for at vi alene har like mange
7464 datamaskiner som de andre til sammen.
</p
>
7468 <li
>Det blir krevd at vi skal innlemmes i de kommunale systemet, og
7469 det er VI som får ansvar for at dette kommer på plass. Og det er her
7470 de horrible tingene begynner å skje.
</li
>
7472 <li
>Det settes opp en lukket Exchange server som gjør av vi ikke kan
7473 hente epost for våre ansatte. Og det kreves at vi finner løsning på
7476 <li
>Det velges sak arkivsystem som vi pålegges å bruke, noe som gjør
7477 at vi må bruke en terminalløsning mot kommunal server. Ikke i seg selv
7478 et problem i følge IKT-ansvarlig hos oss. Men kommunens IT-avd nektet
7479 faktisk å åpne de porter OSV som vi måtte bruke.
</li
>
7481 <li
>Vi blir pålagt å flytte på innsiden av det kommunale
7482 nettverket. Dette gjorde at vi mistet hjemmekontor for lærere og
7483 elever. Å få åpnet porter i kommunal brannmur var ikke
7484 aktuelt. Mulighet for fjerndrift ble også vekk i samme slengen.
</li
>
7486 <li
>Vår LMS Moodle er ikke mulig å nå for elevene og lærerne.
7490 <p
>Den andre ungdomsskolen i kommunen begynner så å kreve at de skal
7491 få bedre datatetthet, og komme opp på et nivå som ligner det vi
7492 har. De ser at vi kan avholde eksamen hvor alle
10. klassingene får
7493 sitte ved hver sin PC. Og de har fått tilbakemelding (klager) fra VGS
7494 om manglende datakompetanse på elevene som kommer fra dem. Dette fører
7495 videre til at kommunen endelig innser at de må ta grep.
</p
>
7497 <p
>Grepet betyr sentralisering, og farvel til vår plattform får vi
7498 høre. Det blir gjort en rekke bestemmelser og vedtak som vi ikke får
7499 være en del av. Det blir helt klart at vi må redusere antall maskiner,
7500 og det skal satses på bærbare maskiner. Siden vi ikke har fått tatt
7501 del i prosessene som angår oss, så bruker vi fagforening. Vi har ikke
7502 blitt hørt i forbindelse med endringer som er betydelig for vår
7503 hverdag, og greier å stoppe omlegging. I tillegg så har vi et politisk
7504 vedtak i kommunen på at vi skal kjøre Linux på elevnett, og dette
7505 vedtaket kan ikke administrasjonen i kommunene helt uten videre
7506 tilsidesette.
</p
>
7508 <p
>I sum har dette gjort at vi har fått jobbe videre i fred. Og en del
7509 runder i kommunens kontrollutvalg har gjort det tydelig at vi har blitt
7510 systematisk motarbeidet.
</p
>
7512 <p
>I dag har de andre skolene fått sine bærbare maskiner til elever og
7513 lærere, men etter
2 år med innkjøring er det fremdeles problemer
7518 <li
>Ungdomsskolen med windows kan ikke kjøre eksamen med sine bærbare,
7519 det er for mye arbeid å renske disse for innhold slik at juks ikke er

>Utskrift er et mareritt, etter sigende pga at utskrift først
7523 sendes til sentral server, og så sendes ut til rett skriver. I snitt
7524 så tar det
7-
8 minutter før utskrift starter på enkelte av
7527 <li
>Trådløst skaper store problemer, og det er i perioder helt umulig
7528 å komme seg på nett. Og lagring på felles server er bare å glemme i
7529 perioder.
</li
>
7533 <p
>Vi har slitt mye, kranglet og sloss. Ikke med tekniske problemer,
7534 men med omgivelsene rundt som vil oss til livs. Men det har vært verdt
7535 hver dråpe med svette, og timer med irritasjon. Men vi har begynt å få
7536 rutine her nå.

7579 leserinnlegg myntet på aviser. Disse er ikke sendt til aviser, men
7580 brukt internt i forbindelse med møter med kommune. Vår IKT-ansvarlig
7581 har også truet med å si opp jobben sin hvis det ikke ble tatt hensyn i
7582 større grad enn hva som har vært tilfelle. VI kan også dokumentere
7583 flere brudd på anbudsregler, og vi kjenner til at relativt store
7584 IT-leverandører som ikke har fått tatt del i disse anbudene, rett og
7585 slett ikke tør melde fra av redsel for å få et dårlig rykte.

7587 <p
>Alt ser ut til å roe seg ned, og vi har fått opp øynene på
7588 politikerne. I sum gjør dette at vi ikke ønsker for mye publisitet nå,
7589 det vil bare rote til igjen.
</p

7591 <p
>Jeg glemte å nevne at vi nå nesten ikke bruker tid på å drifte
7592 systemet vårt, noe som gjør at det aller meste av tid blir brukt til å
7593 støtte lærerne og elevene. F.eks så bruker vår IKT-ansvarlig den
7594 første timen på jobb,
0730-
0830 kun til å gå ute på arbeidsplassene
7595 til læreren. Dette for å kunne svare på små og store problem, gi tips
7596 og råd, eller bare for å plukke opp hva som er behovet ute i
7597 undervisningsarealene. Det er dessverre ikke slik at alle lærerne har
7598 nok digital kompetanse til å kunne formulere alle spørsmålene de har,
7599 men ved å kunne få vise eller lufte tanker med IKT-ansvarlig så er det
7600 utrolig hva som kommer fram.
</p
>
7604 <li
>Jeg ser at mange bruker økonomi som argument i forhold til å bruke
7605 SkoleLinux, og jeg skal ikke legge skjul på at det var dette som i
7606 utgangspunktet var årsaken til vårt valg. Men diskusjonene og kampen
7607 med kommunens IT-avdeling har gjort at vi har fått et noe annet
7608 fokus. Fordelene med drift og stabilitet, gjør at vi ville ha valgt
7609 samme løsning selv om den var dyrere. At vi slipper langt billigere
7610 unna, som følge av
0,- lisenskostnader og lave maskinvarekostnader, er
7611 bare en bonus.
</li
>
7613 <li
>Etter å ha kranglet oss til å få skikkelig oversikt over hva de
7614 andre skolene i kommunen bruker på IT, så har vi fått gehør for å få
7615 samme midler til innkjøp. Dette har gjort at vi nå kan kjøpe inn
7616 utstyr som de andre skolene bare kan se langt etter. Vi har nettopp
7617 kjøpt inn
3 videokamera i semiproff-klassen for å kunne lage film,
7618 samt sende live fra skoleteater/konserter. Vi har kjøpt inn digitale
7619 kompaktkamera til alle klassene. Vi har et team av lærere som skal i
7620 gang med å teste ut tablets på svake elever. Håpet et at teknologien
7621 kan være med på å gi noen av elevene litt mer motivasjon. Vi har kjøpt
7622 inn et halvt klassesett med pulsklokker, noe som har vist seg å være
7623 overraskende inspirerende for en del av elevene. Vi har også oss på
7624 fag på en høyskole litt lengre sør for oss, slik at
3 av oss nå skal
7625 ta faget
"Linux tjenestedrift
". Som inspektør og en del av skolens
7626 administrasjon er det veldig praktisk å kunne trå til hvis det
7627 kniper. Men IKT-ansvarlig har vært UTROLIG flink til å lage rene
7628 smørbrødlister for hvordan de mest vanlige driftsproblem løses, så det
7629 er lett for flere av oss å ta del i den daglige driften. Vi har svært
7630 stor nytte av lærling (som også hjelper to av naboskolene), men det er
7631 nesten blitt slik at det er om å gjøre å komme til først for å få løse
7632 problem. Det å få fingrene på problem og utfordringer er den aller
7633 beste læremester.

7670 years the university have organised shared bid of a few thousand
7671 computers, and this year HP won the bid. Two different desktops and
7672 five different laptops are on the list this year. We in the UNIX
7673 group want to know which one of these computers work well with RHEL
7674 and Ubuntu, the two Linux distributions we currently handle at the
7675 university.

7678 perhaps inspire others to test hardware as well. To test, I PXE
7679 install the OS version of choice, and log in as my normal user and run
7680 a few applications and plug in selected pieces of hardware. When
7681 something fail, I make a note about this in the test matrix and move
7682 on. If I have some spare time I try to report the bug to the OS
7683 vendor, but as I only have the machines for a short time, I rarely
7684 have the time to do this for all the problems I find.

7779 <title>Why isn

7783 <description><p
>In the latest issue of Linux Journal, the readers choices were
7784 presented, and the winner among the multimedia player were VLC.
7785 Personally, I like VLC, and it is my player of choice when I first try
7786 to play a video file or stream. Only if VLC fail will I drag out
7787 gmplayer to see if it can do better. The reason is mostly the failure
7788 model and trust. When VLC fail, it normally pop up a error message
7789 reporting the problem. When mplayer fail, it normally segfault or
7790 just hangs. The latter failure mode drain my trust in the program.
<p
>
7792 <p
>But even if VLC is my player of choice, we have choosen to use
7793 mplayer in
<a href=
"http://www.skolelinux.org/
">Debian
7794 Edu/Skolelinux
</a
>. The reason is simple. We need a good browser
7795 plugin to play web videos seamlessly, and the VLC browser plugin is
7796 not very good. For example, it lack in-line control buttons, so there
7797 is no way for the user to pause the video. Also, when I
7798 <a href=
"http://wiki.debian.org/DebianEdu/BrowserMultimedia
">last
7799 tested the browser plugins
</a
> available in Debian, the VLC plugin
7800 failed on several video pages where mplayer based plugins worked. If
7801 the browser plugin for VLC was as good as the gecko-mediaplayer
7802 package (which uses mplayer), we would switch.
</P
>
7804 <p
>While VLC is a good player, its user interface is slightly
7805 annoying. The most annoying feature is its inconsistent use of
7806 keyboard shortcuts. When the player is in full screen mode, its
7807 shortcuts are different from when it is playing the video in a window.
7808 For example, space only work as pause when in full screen mode. I
7809 wish it had consisten shortcuts and that space also would work when in
7810 window mode. Another nice shortcut in gmplayer is [enter] to restart
7811 the current video. It is very nice when playing short videos from the
7812 web and want to restart it when new people arrive to have a look at
7813 what is going on.

8581 architecture in Debian as a file server in NUUG to get access to the
5
8582 TB zfs volume we currently use to store DV video. Because of this, I
8583 finally got around to do a test installation of Debian/Squeeze with
8584 kfreebsd. Installation went fairly smooth, thought I noticed some
8585 visual glitches in the cdebconf dialogs (black cursor left on the
8586 screen at random locations). Have not gotten very far with the
8587 testing. Noticed cfdisk did not work, but fdisk did so it was not a
8588 fatal problem. Have to spend some more time on it to see if it is
8589 useful as a file server for NUUG. Will try to find time to set up a
8590 gnash buildbot slave on the Debian Edu/Skolelinux this weekend.

>Prioritising packages for the Debian Edu /
8600 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
> DVD, which is
8601 supposed provide a school with all the services and user applications
8602 needed on the pupils computer network has always been hard. Even
8603 schools without Internet connections should be able to get Debian Edu
8604 working using this DVD.
</p
>
8606 <p
>The job became a lot harder when apt and aptitude started
8607 installing recommended packages by default. We want the same set of
8608 packages to be installed when using the DVD and the netinst CD, and
8609 that means all recommended packages need to be on the DVD. I created
8610 a patch for debian-cd in
<a href=
"http://bugs.debian.org/
601203">BTS
8611 report #
601203</a
> to do this, and since this change was applied to
8612 the Debian Edu DVD build, we have been seriously short on space.
</p
>
8614 <p
>A few days ago we decided to drop blender, wxmaxima and kicad from
8615 the default installation to save space on the DVD, believing that
8616 those needing these applications are few and can get them from the
8617 Debian archive.
</p
>
8619 <p
>Yesterday, I had a look what source packages to see which packages
8620 were using most space. A few large packages are well know;
8621 openoffice.org, openclipart and fluid-soundfont. But I also
8622 discovered that lilypond used
106 MiB and fglrx-driver used
53 MiB.
8623 The lilypond package is pulled in as a dependency for rosegarden, and
8624 when looking a bit closer I discovered that
99 MiB of the
106 MiB were
8625 the documentation package, which is recommended by the binary package.
8626 I decided to drop this documentation package from our DVD, as most of
8627 our users will use the GUI front-ends and do not need the lilypond
8628 documentation. Similarly, I dropped the non-free fglrx-driver package
8629 which might be installed by d-i when its hardware is detected, as the
8630 free X driver should work.
</p
>
8632 <p
>With this change, we finally got space for the LXDE and Gnome
8633 desktop packages as well as the language specific packages making the
8634 DVD more useful again.

8645 <p
>My
<a href=
"http://pledgebank.com/gnash-avm2
">gnash pledge
</a
> to
8646 raise money for the project is going well. The lower limit of
10
8647 signers was reached in
24 hours, and so far
13 people have signed it.
8648 More signers and more funding is most welcome, and I am really curious
8649 how far we can get before the time limit of December
24 is reached.
8652 <p
>On the #gnash IRC channel on irc.freenode.net, I was just tipped
8653 about what appear to be a great code coverage tool capable of
8654 generating code coverage stats without any changes to the source code.
8656 <a href=

">kcov

>,
8657 and can be used using
<tt
>kcov
&lt;directory
&gt;
&lt;binary
&gt;
</tt
>.
8658 It is missing in Debian, but the git source built just fine in Squeeze
8659 after I installed libelf-dev, libdwarf-dev, pkg-config and
8660 libglib2.0-dev. Failed to build in Lenny, but suspect that is
8661 solvable. I hope kcov make it into Debian soon.
</p

8663 <p

8668 release. Give it a try if you need a complete linux solution for your
8669 school, including central infrastructure server, workstations, thin
8670 client servers and diskless workstations. A nice touch added
8671 yesterday is RDP support on the thin client servers, for windows
8672 clients to get a Linux desktop on request.

8682 popularity-contest numbers
</a
>, the adobe-flashplugin package the
8683 second most popular used package that is missing in Debian. The sixth
8684 most popular is flashplayer-mozilla. This is a clear indication that
8685 working flash is important for Debian users. Around
10 percent of the
8686 users submitting data to popcon.debian.org have this package
8687 installed.

8689 <p
>In the report written by Lars Risan in August
2008

&target=Skolelinux_i_bruk_rapport_1.0.pdf
">Skolelinux
8691 i bruk – Rapport for Hurum kommune, Universitetet i Agder og
8692 stiftelsen SLX Debian Labs
</a
>»), one of the most important problems
8693 schools experienced with
<a href=
"http://www.skolelinux.org/
">Debian
8694 Edu/Skolelinux
</a
> was the lack of working Flash. A lot of educational
8695 web sites require Flash to work, and lacking working Flash support in
8696 the web browser and the problems with installing it was perceived as a
8697 good reason to stay with Windows.
</p
>
8699 <p
>I once saw a funny and sad comment in a web forum, where Linux was
8700 said to be the retarded cousin that did not really understand
8701 everything you told him but could work fairly well. This was a
8702 comment regarding the problems Linux have with proprietary formats and
8703 non-standard web pages, and is sad because it exposes a fairly common
8704 understanding of whose fault it is if web pages that only work in for
8705 example Internet Explorer
6 fail to work on Firefox, and funny because
8706 it explain very well how annoying it is for users when Linux
8707 distributions do not work with the documents they receive or the web
8708 pages they want to visit.
</p
>
8710 <p
>This is part of the reason why I believe it is important for Debian
8711 and Debian Edu to have a well working Flash implementation in the
8712 distribution, to get at least popular sites as Youtube and Google
8713 Video to working out of the box. For Squeeze, Debian have the chance
8714 to include the latest version of Gnash that will make this happen, as
8715 the new release
0.8.8 was published a few weeks ago and is resting in
8716 unstable. The new version work with more sites that version

8717 The Gnash maintainers have asked for a freeze exception, but the
8718 release team have not had time to reply to it yet. I hope they agree
8719 with me that Flash is important for the Debian desktop users, and thus
8720 accept the new package into Squeeze.

8894 <description><p
>As reported earlier, the last few days I have looked at how Debian
8895 Edu clients are configured, and tried to get rid of all hardcoded
8896 configuration settings on the clients. I believe the work to be
8897 mostly done, and the clients seem to work just fine with dynamically
8898 generated configuration.
</p
>
8900 <p
>What is the point, you might ask? The point is to allow a Debian
8901 Edu desktop to integrate into an existing network infrastructure
8902 without any manual configuration.
</p
>
8904 <p
>This is what happens when installing a Debian Edu client here at
8905 the University of Oslo using PXE. With the PXE installation, I am
8906 asked for language (Norwegian Bokmål), locality (Norway) and keyboard
8907 layout (no-latin1), Debian Edu profile (Roaming Workstation), if I
8908 accept to reformat the hard drive (yes), if I want to submit info to
8909 popcon.debian.org (no) and root password (secret). After answering
8910 these questions, the installer goes ahead and does its thing, and
8911 after around
50 minutes it is done. I press enter to finish the
8912 installation, and the machine reboots into KDE. When the machine is
8913 ready and kdm asks for login information, I enter my university
8914 username and password, am told by kdm that a local home directory has
8915 been created and that I must log in again, and finally log in with the
8916 same username and password to the KDE
4.4 desktop. At no point during
8917 this process did it ask for university specific settings, and all the
8918 required configuration was dynamically detected using information
8919 fetched via DHCP and DNS. The roaming workstation is now ready for
8922 <p
>How was this done, you might wonder? First of all, here is the
8923 list of things that need to be configured on the client to get it
8924 working properly out of the box:
</p
>
8927 <li
>IP address/netmask and DNS server.
</li
>
8928 <li
>Web proxy URL.
</li
>
8929 <li
>LDAP server for NSS directory information (user, group, etc).
</li
>
8930 <li
>Kerberos server for PAM password checking.
</li
>
8931 <li
>SMB mount point to access the network home directory. (*)
</li
>
8932 <li
>Central syslog server to send syslog messages to. (*)
</li
>
8933 <li
>Sitesummary collector URL to submit info to central server. (*)
</li
>
8936 <p
>(Hm, did I forget anything? Let me knew if I did.)
</p
>
8938 <p
>The points marked (*) are not required to be able to use the
8939 machine, but needed to provide central storage and allowing system
8940 administrators to track their machines. Since yesterday, everything
8941 but the sitesummary collector URL is dynamically discovered at boot
8942 and installation time in the svn version of Debian Edu.
</p
>
8944 <p
>The IP and DNS setup is fetched during boot using DHCP as usual.
8945 When a DHCP update arrives, the proxy setup is updated by looking for
8946 http://wpat/wpad.dat and using the content of this WPAD file to
8947 configure the http and ftp proxy in /etc/environment and
8948 /etc/apt/apt.conf. I decided to update the proxy setup using a DHCP
8949 hook to ensure that the client stops using the Debian Edu proxy when
8950 it is moved outside the Debian Edu network, and instead uses any local
8951 proxy present on the new network when it moves around.
</p
>
8953 <p
>The DNS names of the LDAP, Kerberos and syslog server and related
8954 configuration are generated using DNS information at boot. First the
8955 installer looks for a host named ldap in the current DNS domain. If
8956 not found, it looks for _ldap._tcp SRV records in DNS instead. If an
8957 LDAP server is found, its root DSE entry is requested and the
8958 attributes namingContexts and defaultNamingContext are used to
8959 determine which LDAP base to use for NSS. If there are several
8960 namingContexts attibutes and the defaultNamingContext is present, that
8961 LDAP subtree is used as the base. If defaultNamingContext is missing,
8962 the subtrees listed as namingContexts are searched in sequence for any
8963 object with class posixAccount or posixGroup, and the first one with
8964 such an object is used as the LDAP base. For Kerberos, a similar
8965 search is done by first looking for a host named kerberos, and then
8966 for the _kerberos._tcp SRV record. I
've been unable to find a way to
8967 look up the Kerberos realm, so for this the upper case string of the
8968 current DNS domain is used.
</p
>
8970 <p
>For the syslog server, the hosts syslog and loghost are searched
8971 for, and the _syslog._udp SRV record is consulted if no such host is
8972 found. This algorithm works for both Debian Edu and the University of
8973 Oslo. A similar strategy would work for locating the sitesummary
8974 server, but have not been implemented yet. I decided to fetch and
8975 save these settings during installation, to make sure moving to a
8976 different network does not change the set of users being allowed to
8977 log in nor the passwords required to log in. Usernames and passwords
8978 will be cached by sssd when the user logs in on the Debian Edu
8979 network, and will not change as the laptop move around. For a
8980 non-roaming machine, there is no caching, but given that it is
8981 supposed to stay in place it should not matter much. Perhaps we
8982 should switch those to use sssd too?
</p
>
8984 <p
>The user
's SMB mount point for the network home directory is
8985 located when the user logs in for the first time. The LDAP server is
8986 consulted to look for the user
's LDAP object and the sambaHomePath
8987 attribute is used if found. If it isn
't found, the home directory
8988 path fetched from NSS is used instead. Assuming the path is of the
8989 form /site/server/directory/username, the second part is looked up in
8990 DNS and used to generate a SMB URL of the form
8991 smb://server.domain/username. This algorithm works for both Debian
8992 edu and the University of Oslo. Perhaps there are better attributes
8993 to use or a better algorithm that works for more sites, but this will
8994 do for now. :)
</p
>
8996 <p
>This work should make it easier to integrate the Debian Edu clients
8997 into any LDAP/Kerberos infrastructure, and make the current setup even
8998 more flexible than before. I suspect it will also work for thin
8999 client servers, allowing one to easily set up LTSP and hook it into a
9000 existing network infrastructure, but I have not had time to test this
9003 <p
>If you want to help out with implementing these things for Debian
9004 Edu, please contact us on debian-edu@lists.debian.org.
</p
>
9006 <p
>Update
2010-
08-
09: Simon Farnsworth gave me a heads-up on how to
9007 detect Kerberos realm from DNS, by looking for _kerberos TXT entries
9008 before falling back to the upper case DNS domain name. Will have to
9009 implement it for Debian Edu. :)

9018 <description><p
>A few years ago, I was involved in a project planning to use
9019 Windows file servers as home directory servers for Debian
9020 Edu/Skolelinux machines. This was thought to be no problem, as the
9021 access would be through the SMB network file system protocol, and we
9022 knew other sites used SMB with unix and samba as the file server to
9023 mount home directories without any problems. But, after months of
9024 struggling, we had to conclude that our goal was impossible.
</p
>
9026 <p
>The reason is simply that while SMB can be used for home
9027 directories when the file server is Samba running on Unix, this only
9028 work because of Samba have some extensions and the fact that the
9029 underlying file system is a unix file system. When using a Windows
9030 file server, the underlying file system do not have POSIX semantics,
9031 and several programs will fail if the users home directory where they
9032 want to store their configuration lack POSIX semantics.
</p
>
9034 <p
>As part of this work, I wrote a small C program I want to share
9035 with you all, to replicate a few of the problematic applications (like
9036 OpenOffice.org and GCompris) and see if the file system was working as
9037 it should. If you find yourself in spooky file system land, it might

>A few days ago, I
9250 <a href=
"http://people.skolelinux.org/pere/blog/Debian_Edu_roaming_workstation___at_the_university_of_Oslo.html
">tried
9251 to install
</a
> a Roaming workation profile from Debian Edu/Squeeze
9252 while on the university network here at the University of Oslo, and
9253 noticed how much had to change to get it operational using the
9254 university infrastructure. It was fairly easy, but it occured to me
9255 that Debian Edu would improve a lot if I could get the client to
9256 connect without any changes at all, and thus let the client configure
9257 itself during installation and first boot to use the infrastructure
9258 around it. Now I am a huge step further along that road.
</p
>
9260 <p
>With our current squeeze-test packages, I can select the roaming
9261 workstation profile and get a working laptop connecting to the
9262 university LDAP server for user and group and our active directory
9263 servers for Kerberos authentication. All this without any
9264 configuration at all during installation. My users home directory got
9265 a bookmark in the KDE menu to mount it via SMB, with the correct URL.
9266 In short, openldap and sssd is correctly configured. In addition to
9267 this, the client look for http://wpad/wpad.dat to configure a web
9268 proxy, and when it fail to find it no proxy settings are stored in
9269 /etc/environment and /etc/apt/apt.conf. Iceweasel and KDE is
9270 configured to look for the same wpad configuration and also do not use
9271 a proxy when at the university network. If the machine is moved to a
9272 network with such wpad setup, it would automatically use it when DHCP
9273 gave it a IP address.
</p
>
9275 <p
>The LDAP server is located using DNS, by first looking for the DNS
9276 entry ldap.$domain. If this do not exist, it look for the
9277 _ldap._tcp.$domain SRV records and use the first one as the LDAP
9278 server. Next, it connects to the LDAP server and search all
9279 namingContexts entries for posixAccount or posixGroup objects, and
9280 pick the first one as the LDAP base. For Kerberos, a similar
9281 algorithm is used to locate the LDAP server, and the realm is the
9282 uppercase version of $domain.
</p
>
9284 <p
>So, what is not working, you might ask. SMB mounting my home
9285 directory do not work. No idea why, but suspected the incorrect
9286 Kerberos settings in /etc/krb5.conf and /etc/samba/smb.conf might be
9287 the cause. These are not properly configured during installation, and
9288 had to be hand-edited to get the correct Kerberos realm and server,
9289 but SMB mounting still do not work. :(
</p
>
9291 <p
>With this automatic configuration in place, I expect a Debian Edu
9292 roaming profile installation would be able to automatically detect and
9293 connect to any site using LDAP and Kerberos for NSS directory and PAM
9294 authentication. It should also work out of the box in a Active
9295 Directory environment providing posixAccount and posixGroup objects
9296 with UID and GID values.

>The new roaming workstation profile in Debian Edu/Squeeze is fairly
9309 similar to the laptop setup am I working on using Ubuntu for the
9310 University of Oslo, and just for the heck of it, I tested today how
9311 hard it would be to integrate that profile into the university
9312 infrastructure. In this case, it is the university LDAP server,
9313 Active Directory Kerberos server and SMB mounting from the Netapp file
9316 <p
>I was pleasantly surprised that the only three files needed to be
9317 changed (/etc/sssd/sssd.conf, /etc/ldap.conf and
9318 /etc/mklocaluser.d/
20-debian-edu-config) and one file had to be added
9319 (/usr/share/perl5/Debian/Edu_Local.pm), to get the client working.
9320 Most of the changes were to get the client to use the university LDAP
9321 for NSS and Kerberos server for PAM, but one was to change a hard
9322 coded DNS domain name in the mklocaluser hook from .intern to
9325 <p
>This testing was so encouraging, that I went ahead and adjusted the
9326 Debian Edu scripts and setup in subversion to centralise the roaming
9327 workstation setup a bit more and avoid the hardcoded DNS domain name,
9328 so that when I test this tomorrow, I expect to get away with modifying
9329 only /etc/sssd/sssd.conf and /etc/ldap.conf to get it to use the
9330 university servers.
</p
>
9332 <p
>My goal is to get the clients to have no hardcoded settings and
9333 fetch all their initial setup during installation and first boot, to
9334 allow them to be inserted also into environments where the default
9335 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
9466 been working hard to get the Debian/Squeeze based version of Debian
9467 Edu/Skolelinux into shape. This future version will use Kerberos for
9468 authentication, and services are slowly migrated to single signon,
9469 getting rid of password questions one at the time.
</p
>
9471 <p
>It will also feature a roaming workstation profile with local home
9472 directory, for laptops that are only some times on the Skolelinux
9473 network, and for this profile a shortcut is created in Gnome and KDE
9474 to gain access to the users home directory on the file server. This
9475 shortcut uses SMB at the moment, and yesterday I had time to test if
9476 SMB mounting had started working in KDE after we added the cifs-utils
9477 package. I was pleasantly surprised how well it worked.
</p
>
9479 <p
>Thanks to the recent changes to our samba configuration to get it
9480 to use Kerberos for authentication, there were no question about user
9481 password when mounting the SMB volume. A simple click on the shortcut
9482 in the KDE menu, and a window with the home directory popped

9486 Debian Edu. We already had PAM, LDAP, IMAP and SMTP in place, and now
9487 also Samba. Next step is Cups and hopefully also NFS.

9489 <p
>We had planned a alpha0 release of Debian Edu for today, but thanks
9490 to the autobuilder administrators for some architectures being slow to
9491 sign packages, we are still missing the fixed LTSP package we need for
9492 the release. It was uploaded three days ago with urgency=high, and if
9493 it had entered testing yesterday we would have been able to test it in
9494 time for a alpha0 release today. As the binaries for ia64 and powerpc
9495 still not uploaded to the Debian archive, we need to delay the alpha

9827 <description><p
>For a while now, I have wanted to find a way to change the DNS and
9828 DHCP services in Debian Edu to use the same LDAP objects for a given
9829 computer, to avoid the possibility of having a inconsistent state for
9830 a computer in LDAP (as in DHCP but no DNS entry or the other way
9831 around) and make it easier to add computers to LDAP.
</p

9833 <p
>I
've looked at how powerdns and dhcpd is using LDAP, and using this
9834 information finally found a solution that seem to work.
</p
>
9836 <p
>The old setup required three LDAP objects for a given computer.
9837 One forward DNS entry, one reverse DNS entry and one DHCP entry. If
9838 we switch powerdns to use its strict LDAP method (ldap-method=strict
9839 in pdns-debian-edu.conf), the forward and reverse DNS entries are
9840 merged into one while making it impossible to transfer the reverse map
9841 to a slave DNS server.
</p
>
9843 <p
>If we also replace the object class used to get the DNS related
9844 attributes to one allowing these attributes to be combined with the
9845 dhcphost object class, we can merge the DNS and DHCP entries into one.
9846 I
've written such object class in the dnsdomainaux.schema file (need
9847 proper OIDs, but that is a minor issue), and tested the setup. It
9848 seem to work.
</p
>
9850 <p
>With this test setup in place, we can get away with one LDAP object
9851 for both DNS and DHCP, and even the LTSP configuration I suggested in
9852 an earlier email. The combined LDAP object will look something like

9870 before asking DNS to resolve the fixed-adddress. LTSP will use
9871 dhcphwaddress or associateddomain and the ldapconfig* attributes.
</p
>
9873 <p
>I am not yet sure if I can get the DHCP server to look for its
9874 dhcphost in a different location, to allow us to put the objects
9875 outside the
"DHCP Config

9876 that. If I can
't figure out a way to do that, we can still get rid of
9877 the hosts subtree and move all its content into the DHCP Config tree
9878 (which probably should be renamed to be more related to the new

9880 might be a good place to put it.

10096 <description><p
>For a laptop, centralized user directories and password checking is
10097 a bit troubling. Laptops are typically used also when not connected
10098 to the network, and it is vital for a user to be able to log in or
10099 unlock the screen saver also when a central server is unavailable.
10100 This is possible by caching passwords and directory information (user
10101 and group attributes) locally, and the packages to do so are available
10102 in Debian. Here follow two recipes to set this up in Debian/Squeeze.
10103 It is also possible to set up in Debian/Lenny, but require more manual
10104 setup there because pam-auth-update is missing in Lenny.
</p
>
10106 <h2
>LDAP/Kerberos + nscd + libpam-ccreds + libpam-mklocaluser/pam_mkhomedir
</h2
>
10108 This is the traditional method with a twist. The password caching is
10109 provided by libpam-ccreds (version
10-
4 or later is needed on
10110 Squeeze), and the directory caching is done by nscd. The directory
10111 lookup and password checking is done using LDAP. If one want to use
10112 Kerberos for password checking the libpam-ldapd package can be
10113 replaced with libpam-krb5 or libpam-heimdal. If one is happy having a
10114 local home directory with the path listed in LDAP, one can use the
10115 pam_mkhomedir module from pam-modules to make this happen instead of
10116 using libpam-mklocaluser. A setup for pam-auth-update to enable
10117 pam_mkhomedir will have to be written until a fix for
10118 <a href=
"http://bugs.debian.org/
568577">bug #
568577</a
> is in the
10119 archive. Because I believe it is a bad idea to have local home
10120 directories using misleading paths like /site/server/partition/, I
10121 prefer to create a local user with the home directory in /home/. This
10122 is done using the libpam-mklocaluser package.

>The last few days I have been looking into the status of the LDAP
10303 directory in Debian Edu, and in the process I started to miss a GUI
10304 tool to browse the LDAP tree. The only one I was able to find in
10305 Debian/Squeeze and Lenny is
10306 <a href=
"http://luma.sourceforge.net/
">LUMA
</a
>, which has proved to
10307 be a great tool to get a overview of the current LDAP directory
10308 populated by default in Skolelinux. Thanks to it, I have been able to
10309 find empty and obsolete subtrees, misplaced objects and duplicate
10310 objects. It will be installed by default in Debian/Squeeze. If you
10311 are working with LDAP, give it a go. :)
</p
>
10313 <p
>I did notice one problem with it I have not had time to report to
10314 the BTS yet. There is no .desktop file in the package, so the tool do
10315 not show up in the Gnome and KDE menus, but only deep down in in the
10316 Debian submenu in KDE. I hope that can be fixed before Squeeze is
10317 released.
</p
>
10319 <p
>I have not yet been able to get it to modify the tree yet. I would
10320 like to move objects and remove subtrees directly in the GUI, but have
10321 not found a way to do that with LUMA yet. So in the mean time, I use
10322 <a href=

10328 <a href=
"http://packages.qa.debian.org/g/gq.html
">gq
</a
> package as a
10329 useful GUI alternative. It seem like a good tool, but is unmaintained
10330 in Debian and got a RC bug keeping it out of Squeeze. Unless that
10331 changes, it will not be an option for Debian Edu based on Squeeze.

</p

10346 <p
>In the mean time, I discovered that a simple fix would be to make
10347 the dhcpHost object class auxiliary, to allow it to be combined with

10351 <p

>For KDE, apt-get want to remove
82 packages, among them kdebase
10409 which seem like a bad idea and xorg the same way as with Gnome. Asking
10410 aptitude for the same, it wants to remove
192 packages, none which are
10411 too surprising.

10414 and avoided, and perhaps others as well. Here are the complete list
10415 of planned removals. The complete logs is available from the URL
10416 above. Note if you want to repeat these tests, that the upgrade test
10417 for kde+apt-get hung in the tasksel setup because of dpkg asking
10418 conffile questions. No idea why. I worked around it by using
10419 '<tt

10566 <description><p
>The last few days I have done some upgrade testing in Debian, to
10567 see if the upgrade from Lenny to Squeeze will go smoothly. A few bugs
10568 have been discovered and reported in the process
10569 (
<a href=
"http://bugs.debian.org/
585410">#
585410</a
> in nagios3-cgi,
10570 <a href=
"http://bugs.debian.org/
584879">#
584879</a
> already fixed in
10571 enscript and
<a href=
"http://bugs.debian.org/
584861">#
584861</a
> in
10572 kdebase-workspace-data), and to get a more regular testing going on, I
10573 am working on a script to automate the test.
</p
>
10575 <p
>The idea is to create a Lenny chroot and use tasksel to install a
10576 Gnome or KDE desktop installation inside the chroot before upgrading
10577 it. To ensure no services are started in the chroot, a policy-rc.d
10578 script is inserted. To make sure tasksel believe it is to install a
10579 desktop on a laptop, the tasksel tests are replaced in the chroot
10580 (only acceptable because this is a throw-away chroot).
</p
>
10582 <p
>A naive upgrade from Lenny to Squeeze using aptitude dist-upgrade
10583 currently always fail because udev refuses to upgrade with the kernel
10584 in Lenny, so to avoid that problem the file /etc/udev/kernel-upgrade
10585 is created. The bug report
10586 <a href=
"http://bugs.debian.org/
566000">#
566000</a
> make me suspect
10587 this problem do not trigger in a chroot, but I touch the file anyway
10588 to make sure the upgrade go well. Testing on virtual and real
10589 hardware have failed me because of udev so far, and creating this file
10590 do the trick in such settings anyway. This is a
10591 <a href=
"http://www.linuxquestions.org/questions/debian-
26/failed-dist-upgrade-due-to-udev-config_sysfs_deprecated-nonsense-
804130/
">known
10592 issue
</a
> and the current udev behaviour is intended by the udev
10593 maintainer because he lack the resources to rewrite udev to keep
10594 working with old kernels or something like that. I really wish the
10595 udev upstream would keep udev backwards compatible, to avoid such
10596 upgrade problem, but given that they fail to do so, I guess
10597 documenting the way out of this mess is the best option we got for
10598 Debian Squeeze.

>Som systemarkitekten bak Skolelinux, kan jeg bare riste på hodet
10724 over påstanden om at Skolelinux krever desentraliserte tjenere.
10725 Skolelinux-arkitekturen er laget for sentralisert drift og plassering
10726 av tjenerne lokalt eller sentralt alt etter behov og nettkapasitet.
10727 Den er modellert på nettverks- og tjenerløsningen som brukes på
10728 Universitetet i Tromsø og Oslo, der jeg jobber med utvikling av
10729 driftstjenester. Dette er det heldigvis noen som har fått med seg, og
10730 jeg er glad for å kunne sitere fra en kommentar på den overnevnte
10731 artikkelen. Min venn og gamle kollega Sturle Sunde forteller der:
10734 <p
>I Flora kommune køyrer vi Skulelinux på skular med alt frå
15 til
10735 meir enn
500 elevar. Dei store skulane har eigen tenar, for det er
10736 mest praktisk. Eg, som er driftsansvarleg for heile nettet, ser
10737 sjeldan dei tenarane fysisk, men at dei står der gjer skulane mindre
10738 avhengige av eksterne linjer som er trege eller dyre. Dei minste
10739 skulane har ikkje eigen tenar. Å bruke sentral tenar er heller ikkje
10740 noko problem. Småskulane klarar seg fint med
1 mbit-linje til ein
10741 sentral tenar eller tenaren på ein større skule.
</p
>
10743 <p
>Det beste med Skulelinux er halvtjukke klientar. Dei treng ikkje
10744 harddisk og brukar minimalt med ressursar på tenaren fordi dei køyrer
10745 programma lokalt. Eit klasserom med
30 sju-åtte år gamle maskiner har
10746 mykje meir CPU og RAM totalt enn nokon moderne tenar til under
10747 millionen. Det trengst to kommandoar på den sentrale tenaren for å
10748 oppdatere alle klientane, både tynne og halvtjukke. Vi har ingen

>After a long break from debian-installer development, I finally
10911 found time today to return to the project. Having to spend less time
10912 working dependency based boot in debian, as it is almost complete now,
10913 definitely helped freeing some time.
</p
>
10915 <p
>A while back, I ran into a problem while working on Debian Edu. We
10916 include some firmware packages on the Debian Edu CDs, those needed to
10917 get disk and network controllers working. Without having these
10918 firmware packages available during installation, it is impossible to
10919 install Debian Edu on the given machine, and because our target group
10920 are non-technical people, asking them to provide firmware packages on
10921 an external medium is a support pain. Initially, I expected it to be
10922 enough to include the firmware packages on the CD to get
10923 debian-installer to find and use them. This proved to be wrong.
10924 Next, I hoped it was enough to symlink the relevant firmware packages
10925 to some useful location on the CD (tried /cdrom/ and
10926 /cdrom/firmware/). This also proved to not work, and at this point I
10927 found time to look at the debian-installer code to figure out what was
10928 going to work.
</p
>
10930 <p
>The firmware loading code is in the hw-detect package, and a closer
10931 look revealed that it would only look for firmware packages outside
10932 the installation media, so the CD was never checked for firmware
10933 packages. It would only check USB sticks, floppies and other
10934 "external
" media devices. Today I changed it to also look in the
10935 /cdrom/firmware/ directory on the mounted CD or DVD, which should
10936 solve the problem I ran into with Debian edu. I also changed it to
10937 look in /firmware/, to make sure the installer also find firmware
10938 provided in the initrd when booting the installer via PXE, to allow us
10939 to provide the same feature in the PXE setup included in Debian
10942 <p
>To make sure firmware deb packages with a license questions are not
10943 activated without asking if the license is accepted, I extended
10944 hw-detect to look for preinst scripts in the firmware packages, and
10945 run these before activating the firmware during installation. The
10946 license question is asked using debconf in the preinst, so this should
10947 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
10960 Edu finally entered the Debian archive. Today, the new
10961 <a href=
"http://packages.qa.debian.org/libp/libpam-mklocaluser.html
">libpam-mklocaluser
</a
>
10962 package was accepted. Two days ago, two other pieces was accepted
10964 <a href=
"http://packages.qa.debian.org/p/pam-python.html

10965 package needed by libpam-mklocaluser, and the
10966 <a href=
"http://packages.qa.debian.org/s/sssd.html
">sssd
</a

10967 passed NEW on Monday. In addition, the
10968 <a href=
"http://packages.qa.debian.org/libp/libpam-ccreds.html
">libpam-ccreds
</a
>
10969 package we need is in experimental (version
10-
4) since Saturday, and
10970 hopefully will be moved to unstable soon.
</p
>
10972 <p
>This collection of packages allow for two different setups for
10973 roaming laptops. The traditional setup would be using libpam-ccreds,
10974 nscd and libpam-mklocaluser with LDAP or Kerberos authentication,
10975 which should work out of the box if the configuration changes proposed
10976 for nscd in
<a href=
"http://bugs.debian.org/
485282">BTS report
10977 #
485282</a
> is implemented. The alternative setup is to use sssd with
10978 libpam-mklocaluser to connect to LDAP or Kerberos and let sssd take
10979 care of the caching of passwords and group information.
</p
>
10981 <p
>I have so far been unable to get sssd to work with the LDAP server
10982 at the University, but suspect the issue is some SSL/GnuTLS related
10983 problem with the server certificate. I plan to update the Debian
10984 package to version
1.2, which is scheduled for next week, and hope to
10985 find time to make sure the next release will include both the
10986 Debian/Ubuntu specific patches. Upstream is friendly and responsive,
10987 and I am sure we will find a good solution.
</p
>
10989 <p
>The idea is to set up the roaming laptops to authenticate using
10990 LDAP or Kerberos and create a local user with home directory in /home/
10991 when a usre in LDAP logs in via KDM or GDM for the first time, and
10992 cache the password for offline checking, as well as caching group
10993 memberhips and other relevant LDAP information. The
10994 libpam-mklocaluser package was created to make sure the local home
10995 directory is in /home/, instead of /site/server/directory/ which would
10996 be the home directory if pam_mkhomedir was used. To avoid confusion
10997 with support requests and configuration, we do not want local laptops
10998 to have users in a path that is used for the same users home directory
10999 on the home directory servers.
</p
>
11001 <p
>One annoying problem with gdm is that it do not show the PAM
11002 message passed to the user from libpam-mklocaluser when the local user
11003 is created. Instead gdm simply reject the login with some generic
11004 message. The message is shown in kdm, ssh and login, so I guess it is
11005 a bug in gdm. Have not investigated if there is some other message
11006 type that can be used instead to get gdm to also show the message.

11163 <description><p
>For some years now, I have wondered how we should handle laptops in
11164 Debian Edu. The Debian Edu infrastructure is mostly designed to
11165 handle stationary computers, and less suited for computers that come
11168 <p
>Now I finally believe I have an sensible idea on how to adjust
11169 Debian Edu for laptops, by introducing a new profile for them, for
11170 example called Roaming Workstations. Here are my thought on this.
11171 The setup would consist of the following:
</p
>
11175 <li
>During installation, the user name of the owner / primary user of
11176 the laptop is requested and a local home directory is set up for
11177 the user, with uid and gid information fetched from the LDAP
11178 server. This allow the user to work also when offline. The
11179 central home directory can be available in a subdirectory on
11180 request, for example mounted via CIFS. It could be mounted
11181 automatically when a user log in while on the Debian Edu network,
11182 and unmounted when the machine is taken away (network down,
11183 hibernate, etc), it can be set up to do automatic mounting on
11184 request (using autofs), or perhaps some GUI button on the desktop
11185 can be used to access it when needed. Perhaps it is enough to use
11186 the fish protocol in KDE?
</li
>
11188 <li
>Password checking is set up to use LDAP or Kerberos
11189 authentication when the machine is on the Debian Edu network, and
11190 to cache the password for offline checking when the machine unable
11191 to reach the LDAP or Kerberos server. This can be done using
11192 <a href=
"http://www.padl.com/OSS/pam_ccreds.html
">libpam-ccreds
</a
>
11193 or the Fedora developed
11194 <a href=
"https://fedoraproject.org/wiki/Features/SSSD
">System
11195 Security Services Daemon
</a
> packages.
</li
>
11197 <li
>File synchronisation with the central home directory is set up
11198 using a shared directory in both the local and the central home
11199 directory, using unison.
</li
>
11201 <li
>Printing should be set up to print to all printers broadcasting
11202 their existence on the local network, and should then work out of
11203 the box with CUPS. For sites needing accurate printer quotas, some
11204 system with Kerberos authentication or printing via ssh could be
11205 implemented.
</li
>
11207 <li
>For users that should have local root access to their laptop,
11208 sudo should be used to allow this to the local user.
</li
>
11210 <li
>It would be nice if user and group information from LDAP is
11211 cached on the client, but given that there are entries for the
11212 local user and primary group in /etc/, it should not be needed.
</li
>
11216 <p
>I believe all the pieces to implement this are in Debian/testing at
11217 the moment. If we work quickly, we should be able to get this ready
11218 in time for the Squeeze release to freeze. Some of the pieces need
11219 tweaking, like libpam-ccreds should get support for pam-auth-update
11220 (
<a href=
"http://bugs.debian.org/
566718">#
566718</a
>) and nslcd (or
11221 perhaps debian-edu-config) should get some integration code to stop
11222 its daemon when the LDAP server is unavailable to avoid long timeouts
11223 when disconnected from the net. If we get Kerberos enabled, we need
11224 to make sure we avoid long timeouts there too.

">Yesterdays
11237 NUUG presentation
</a
> about Kerberos was inspiring, and reminded me
11238 about the need to start using Kerberos in Skolelinux. Setting up a
11239 Kerberos server seem to be straight forward, and if we get this in
11240 place a long time before the Squeeze version of Debian freezes, we
11241 have a chance to migrate Skolelinux away from NFSv3 for the home
11242 directories, and over to an architecture where the infrastructure do
11243 not have to trust IP addresses and machines, and instead can trust
11244 users and cryptographic keys instead.
</p
>
11246 <p
>A challenge will be integration and administration. Is there a
11247 Kerberos implementation for Debian where one can control the
11248 administration access in Kerberos using LDAP groups? With it, the
11249 school administration will have to maintain access control using flat
11250 files on the main server, which give a huge potential for errors.
</p
>
11252 <p
>A related question I would like to know is how well Kerberos and
11253 pam-ccreds (offline password check) work together. Anyone know?
</p
>
11255 <p
>Next step will be to use Kerberos for access control in Lwat and
11256 Nagios. I have no idea how much work that will be to implement. We
11257 would also need to document how to integrate with Windows AD, as such
11258 shared network will require two Kerberos realms that need to cooperate
11259 to work properly.
</p
>
11261 <p
>I believe a good start would be to start using Kerberos on the
11262 skolelinux.no machines, and this way get ourselves experience with
11263 configuration and integration. A natural starting point would be
11264 setting up ldap.skolelinux.no as the Kerberos server, and migrate the
11265 rest of the machines from PAM via LDAP to PAM via Kerberos one at the
11268 <p
>If you would like to contribute to get this working in Skolelinux,
11269 I recommend you to see the video recording from yesterdays NUUG
11270 presentation, and start using Kerberos at home. The video show show
11271 up in a few days.

>6 years ago, as part of the Debian Edu development I am involved
11281 in, I asked for a hook in the kdm and gdm setup to run scripts as root
11282 when the user log out. A bug was submitted against the xfree86-common
11283 package in
2004 (
<a href=
"http://bugs.debian.org/
230422">#
230422</a

11284 and revisited every time Debian Edu was working on a new release.
11285 Today, this finally paid off.
</p
>
11287 <p
>The framework for this feature was today commited to the git
11288 repositry for the xorg package, and the git repository for xdm has
11289 been updated to use this framework. Next on my agenda is to make sure
11290 kdm and gdm also add code to use this framework.
</p
>
11292 <p
>In Debian Edu, we want to ability to run commands as root when the
11293 user log out, to get rid of runaway processes and do general cleanup
11294 after a user. With this framework in place, we finally can do that in
11295 a generic way that work with all display managers using this
11296 framework. My goal is to get all display managers in Debian use it,
11297 similar to how they use the Xsession.d framework today.

>One of the new features in the next Debian/Lenny based release of
11329 Debian Edu/Skolelinux, which is scheduled for release in the next few
11330 days, is automatic configuration of the service monitoring system
11331 Nagios. The previous release had automatic configuration of trend
11332 analysis using Munin, and this Lenny based release take that a step
11335 <p
>When installing a Debian Edu Main-server, it is automatically
11336 configured as a Munin and Nagios server. In addition, it is
11337 configured to be a server for the
11338 <a href=
"http://wiki.debian.org/DebianEdu/HowTo/SiteSummary
">SiteSummary
11339 system
</a
> I have written for use in Debian Edu. The SiteSummary
11340 system is inspired by a system used by the University of Oslo where I
11341 work. In short, the system provide a centralised collector of
11342 information about the computers on the network, and a client on each
11343 computer submitting information to this collector. This allow for
11344 automatic information on which packages are installed on each machine,
11345 which kernel the machines are using, what kind of configuration the
11346 packages got etc. This also allow us to automatically generate Munin
11347 and Nagios configuration.
</p
>
11349 <p
>All computers reporting to the sitesummary collector with the
11350 munin-node package installed is automatically enabled as a Munin
11351 client and graphs from the statistics collected from that machine show
11352 up automatically on http://www/munin/ on the Main-server.
</p
>
11354 <p
>All non-laptop computers reporting to the sitesummary collector are
11355 automatically monitored for network presence (ping and any network
11356 services detected). In addition, all computers (also laptops) with
11357 the nagios-nrpe-server package installed and configured the way
11358 sitesummary would configure it, are monitored for full disks, software
11359 raid status, swap free and other checks that need to run locally on
11360 the machine.
</p
>
11362 <p
>The result is that the administrator on a school using Debian Edu
11363 based on Lenny will be able to check the health of his installation
11364 with one look at the Nagios settings, without having to spend any time
11365 keeping the Nagios configuration up-to-date.
</p
>
11367 <p
>The only configuration one need to do to get Nagios up and running
11368 is to set the password used to get access via HTTP. The system
11369 administrator need to run
"<tt
>htpasswd /etc/nagios3/htpasswd.users
11370 nagiosadmin
</tt
>" to create a nagiosadmin user and set a password for
11371 it to be able to log into the Nagios web pages. After that,
11372 everything is taken care of.

11445 30 people participated, and I believe it was a great environment to
11446 get to know the Skolelinux system. Walter Bender, involved in the
11447 development of the Sugar educational platform, presented his stuff and
11448 also helped me improve my OLPC installation. He also showed me that
11449 his Turtle Art application can be used in standalone mode, and we
11450 agreed that I would help getting it packaged for Debian. As a
11451 standalone application it would be great for Debian Edu. We also
11452 tried to get the video conferencing working with two OLPCs, but that

11506 Et langt steg videre for Debian-prosjektet, og en rekke nye
11507 programpakker blir nå tilgjengelig for de av oss som bruker den

>Etter flere års mislykkede forsøk på å skrive om byggesystemet for
11525 <a href=
"http://no.speling.org/
">den norske stavekontrollen for bokmål
11526 og nynorsk
</a
> til å ikke bruke bindestrek som ordskillemarkør, lyktes jeg
11527 endelig første juledag. Bruken av bindestrek som ordskillemarkør har
11528 gjort det umulig å få med ord med bindestrek i
11529 stavekontrolldatagrunnlaget, slik at ord som e-post og CD-spiller ikke
11530 kunne godtas av stavekontrollen. Hadde litt tid til overs å bruke på
11531 stavekontrollen, og satte meg ned med to kopier av byggsystemet og en
11532 liten testdatafil, og byttet ut - med = på utvalgte steder i
11533 byggsystemet og datafilen helt til jeg fikk samme resultat med det
11534 gamle og det nye byggsystemet. Dette tror jeg var forsøk
4, der de
11535 foregående har feilet uten at jeg klarte å forstå hvorfor. Det sier
11536 kanskje litt om kompleksiteten i det originale byggsystemet som Rune
11537 Kleveland laget i sin tid.
</p
>
11539 <p
>Etter å ha endret byggsystemet, var neste steg å importere ordene
11540 med bindestrek. Vi har en rekke slike i databasene for
11541 <a href=
"http://tyge.sslug.dk/~korsvoll/nb.speling.org/htdocs/
">bokmål
</a
>
11543 <a href=
"http://tyge.sslug.dk/~korsvoll/nn.speling.org/htdocs/
">nynorsk
</a
>
11544 for korrektur av datagrunnlaget for stavekontrollen, og etter importen
11545 skulle nå
10350 nye ord bli godkjent som korrekt stavede ord av
11546 stavekontrollen.

>This weekend we had a small developer gathering for Debian Edu in
11556 Oslo. Most of Saturday was used for the general assemly for the
11557 member organization, but the rest of the weekend I used to tune the
11558 LTSP installation. LTSP now work out of the box on the
10-network.
11559 Acer Aspire One proved to be a very nice thin client, with both
11560 screen, mouse and keybard in a small box. Was working on getting the
11561 diskless workstation setup configured out of the box, but did not
11562 finish it before the weekend was up.

11564 <p
>Did not find time to look at the
4 VGA cards in one box we got from
11565 the Brazilian group, so that will have to wait for the next
11566 development gathering. Would love to have the Debian Edu installer
11567 automatically detect and configure a multiseat setup when it find one
11568 of these cards.

>Recently I have spent some time evaluating the multimedia browser
11578 plugins available in Debian Lenny, to see which one we should use by
11579 default in Debian Edu. We need an embedded video playing plugin with
11580 control buttons to pause or stop the video, and capable of streaming
11581 all the multimedia content available on the web. The test results and
11582 notes are available on
11583 <a href=
"http://wiki.debian.org/DebianEdu/BrowserMultimedia
">the
11584 Debian wiki
</a
>. I was surprised how few of the plugins are able to
11585 fill this need. My personal video player favorite, VLC, has a really
11586 bad plugin which fail on a lot of the test pages. A lot of the MIME
11587 types I would expect to work with any free software player (like
11588 video/ogg), just do not work. And simple formats like the
11589 audio/x-mplegurl format (m3u playlists), just isn
't supported by the
11590 totem and vlc plugins. I hope the situation will improve soon. No
11591 wonder sites use the proprietary Adobe flash to play video.
