-<p>One interesting feature in Active Directory, is the ability to
-create a new user with an expired password, and thus force the user to
-change the password on the first login attempt.</p>
-
-<p>I'm not quite sure how to do that with the LDAP setup in Debian
-Edu, but did some initial testing with a local account. The account
-and password aging information is available in /etc/shadow, but
-unfortunately, it is not possible to specify an expiration time for
-passwords, only a maximum age for passwords.</p>
-
-<p>A freshly created account (using adduser test) will have these
-settings in /etc/shadow:</p>
-
-<blockquote><pre>
-root@tjener:~# chage -l test
-Last password change : May 02, 2010
-Password expires : never
-Password inactive : never
-Account expires : never
-Minimum number of days between password change : 0
-Maximum number of days between password change : 99999
-Number of days of warning before password expires : 7
-root@tjener:~#
-</pre></blockquote>
-
-<p>The only way I could come up with to create a user with an expired
-account, is to change the date of the last password change to the
-lowest value possible (January 1th 1970), and the maximum password age
-to the difference in days between that date and today. To make it
-simple, I went for 30 years (30 * 365 = 10950) and January 2th (to
-avoid testing if 0 is a valid value).</p>
-
-<p>After using these commands to set it up, it seem to work as
-intended:</p>
-
-<blockquote><pre>
-root@tjener:~# chage -d 1 test; chage -M 10950 test
-root@tjener:~# chage -l test
-Last password change : Jan 02, 1970
-Password expires : never
-Password inactive : never
-Account expires : never
-Minimum number of days between password change : 0
-Maximum number of days between password change : 10950
-Number of days of warning before password expires : 7
-root@tjener:~#
-</pre></blockquote>
-
-<p>So far I have tested this with ssh and console, and kdm (in
-Squeeze) login, and all ask for a new password before login in the
-user (with ssh, I was thrown out and had to log in again).</p>
-
-<p>Perhaps we should set up something similar for Debian Edu, to make
-sure only the user itself have the account password?</p>
-
-<p>If you want to comment on or help out with implementing this for
-Debian Edu, please contact us on debian-edu@lists.debian.org.</p>
-
-<p>Update 2010-05-02 17:20: Paul Tötterman tells me on IRC that the
-shadow(8) page in Debian/testing now state that setting the date of
-last password change to zero (0) will force the password to be changed
-on the first login. This was not mentioned in the manual in Lenny, so
-I did not notice this in my initial testing. I have tested it on
-Squeeze, and '<tt>chage -d 0 username</tt>' do work there. I have not
-tested it on Lenny yet.</p>
-
-<p>Update 2010-05-02-19:05: Jim Paris tells me via email that an
-equivalent command to expire a password is '<tt>passwd -e
-username</tt>', which insert zero into the date of the last password
-change.</p>

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

-please contact us on debian-edu@lists.debian.org.</p>
+<p>Debatten rundt sporveiselskapet i Oslos (Ruter AS) ønske om
+<a href="http://www.aftenposten.no/nyheter/iriks/article3808135.ece">å

+<a href="http://www.aftenposten.no/nyheter/article3809746.ece">registerere
+hvor hver og en av oss beveger oss</a> pågår, og en ting som har
+kommet lite frem i debatten er at det faktisk er en menneskerett å
+kunne ferdes anonymt internt i ens eget land.</p>
+
+<p>Fant en grei kilde for dette i et
+<a href="http://www.datatilsynet.no/upload/Microsoft%20Word%20-%2009-01399-2%20H+%C2%A9ringsnotat%20-%20Samferdselsdepartementet%20-%20Utkas%C3%94%C3%87%C2%AA.pdf">skriv
+fra Datatilsynet</a> til Samferdselsdepartementet om tema:</p>
+
+<blockquote><p>Retten til å ferdes anonymt kan utledes av
+menneskerettskonvensjonen artikkel 8 og av EUs personverndirektiv.
+Her heter det at enkeltpersoners grunnleggende rettigheter og frihet
+må respekteres, særlig retten til privatlivets fred. I både
+personverndirektivet og i den norske personopplysningsloven er
+selvråderetten til hver enkelt et av grunnprinsippene, hovedsaklig
+uttrykt ved at en må gi et frivillig, informert og uttrykkelig
+samtykke til behandling av personopplysninger.</p></blockquote>
+
+<p>For meg er det viktig at jeg kan ferdes anonymt, og det er litt av
+bakgrunnen til at jeg handler med kontanter, ikke har mobiltelefon og
+forventer å kunne reise med bil og kollektivtrafikk uten at det blir
+registrert hvor jeg har vært. Ruter angriper min rett til å ferdes
+uten radiopeiler med sin innføring av RFID-kort, og dokumenterer sitt
+ønske om å registrere hvor kundene befant seg ved å ønske å gebyrlegge
+oss som ikke registrerer oss hver gang vi beveger oss med
+kollektivtrafikken i Oslo. Jeg synes det er hårreisende.</p>

<div class="body">
-<p>The last few weeks i have had the pleasure of reading a
-thought-provoking collection of essays by Cory Doctorow, on topics
-touching copyright, virtual worlds, the future of man when the
-conscience mind can be duplicated into a computer and many more. The
-book titled "Content: Selected Essays on Technology, Creativity,
-Copyright, and the Future of the Future" is available with few
-restrictions on the web, for example from
-<a href="http://craphound.com/content/">his own site</a>. I read the
-epub-version from
-<a href="http://www.feedbooks.com/book/2883">feedbooks</a> using
-<a href="http://www.fbreader.org/">fbreader</a> and my N810. I
-strongly recommend this book.</p>
+<p>A few days ago I had the mixed pleasure of bying a new digital
+camera, a Canon IXUS 130. It was instructive and very disturbing to
+be able to verify that also this camera producer have the nerve to
+specify how I can or can not use the videos produced with the camera.
+Even thought I was aware of the issue, the options with new cameras
+are limited and I ended up bying the camera anyway. What is the
+problem, you might ask? It is software patents, MPEG-4, H.264 and the
+MPEG-LA that is the problem, and our right to record our experiences
+without asking for permissions that is at risk.
+
+<p>On page 27 of the Danish instruction manual, this section is
+written:</p>
+
+<blockquote>
+<p>This product is licensed under AT&T patents for the MPEG-4 standard
+and may be used for encoding MPEG-4 compliant video and/or decoding
+MPEG-4 compliant video that was encoded only (1) for a personal and
+non-commercial purpose or (2) by a video provider licensed under the
+AT&T patents to provide MPEG-4 compliant video.</p>
+
+<p>No license is granted or implied for any other use for MPEG-4
+standard.</p>
+</blockquote>
+
+<p>In short, the camera producer have chosen to use technology
+(MPEG-4/H.264) that is only provided if I used it for personal and
+non-commercial purposes, or ask for permission from the organisations
+holding the knowledge monopoly (patent) for technology used.</p>
+
+<p>This issue has been brewing for a while, and I recommend you to
+read
+"<a href="http://www.osnews.com/story/23236/Why_Our_Civilization_s_Video_Art_and_Culture_is_Threatened_by_the_MPEG-LA">Why
+Our Civilization's Video Art and Culture is Threatened by the

+"<a href="http://webmink.com/2010/09/03/h-264-and-foss/">H.264 Is Not
+The Sort Of Free That Matters</a>" by Simon Phipps to learn more about
+the issue. The solution is to support the
+<a href="http://www.digistan.org/open-standard:definition">free and
+open standards</a> for video, like <a href="http://www.theora.org/">Ogg
+Theora</a>, and avoid MPEG-4 and H.264 if you can.</p>

-<p><a href="http://www.nuug.no/aktiviteter/20100413-kerberos/">Yesterdays
-NUUG presentation</a> about Kerberos was inspiring, and reminded me
-about the need to start using Kerberos in Skolelinux. Setting up a
-Kerberos server seem to be straight forward, and if we get this in
-place a long time before the Squeeze version of Debian freezes, we
-have a chance to migrate Skolelinux away from NFSv3 for the home
-directories, and over to an architecture where the infrastructure do
-not have to trust IP addresses and machines, and instead can trust
-users and cryptographic keys instead.</p>
-
-<p>A challenge will be integration and administration. Is there a
-Kerberos implementation for Debian where one can control the
-administration access in Kerberos using LDAP groups? With it, the
-school administration will have to maintain access control using flat
-files on the main server, which give a huge potential for errors.</p>
-
-<p>A related question I would like to know is how well Kerberos and
-pam-ccreds (offline password check) work together. Anyone know?</p>
-
-<p>Next step will be to use Kerberos for access control in Lwat and
-Nagios. I have no idea how much work that will be to implement. We
-would also need to document how to integrate with Windows AD, as such
-shared network will require two Kerberos realms that need to cooperate
-to work properly.</p>
-
-<p>I believe a good start would be to start using Kerberos on the
-skolelinux.no machines, and this way get ourselves experience with
-configuration and integration. A natural starting point would be
-setting up ldap.skolelinux.no as the Kerberos server, and migrate the
-rest of the machines from PAM via LDAP to PAM via Kerberos one at the
-time.</p>
-
-<p>If you would like to contribute to get this working in Skolelinux,
-I recommend you to see the video recording from yesterdays NUUG
-presentation, and start using Kerberos at home. The video show show
-up in a few days.</p>
+<p>Jeg ble riktig fascinert av
+<a href="http://www.aftenposten.no/nyheter/iriks/article3800967.ece">en
+artikkel i Aftenposten</a> om hvor hardt Navteq jobber for å oppdatere
+kartene som brukes i navigasjons-GPSer, der det blant annet heter at
+"på grunn av teknikken tar det alt fra tre til tolv måneder før
+kartene er oppdatert". Når en kjenner hva slags oppdateringshastighet
+som er tilgjengelig på
+<a href="http://www.openstreetmap.org/">OpenStreetmap</a> som
+oppdateres på dugnad, blir det litt trist å se hva noe av det beste en
+kan kjøpe for penger får til.</p>
+
+<p>Fra en endrer kartdataene i databasen til OpenStreetmap tar det
+ca. 15 minutter før endringen er synlig på kartet som alle kan se på
+web. Dernest overføres det daglig til en kartdump som lastes ned av
+personen som lager Garmin-kart for Norge ca. en gang i uken. Med
+OpenStreetmap.org og <a href="http://www.frikart.no/">Frikart.no</a>
+kan en altså ha korreksjonene på plass i sin Garmin-GPS i løpet av en
+uke. Det er også av tekniske årsaker at det tar så langt tid.
+Jobbene som tegner kartene, henter ut kartdumpene og konverterer til
+Garmin-format tar minutter og timer å gjennomføre, slik at de ikke
+gjøres kontinuerlig men kun regelmessing.</p>

-<p>Det hele bringer tankene tilbake til Sture Hansen i Hallo i Uken.</p>
+<p>In the <a href="http://popcon.debian.org/unknown/by_vote">Debian
+popularity-contest numbers</a>, the adobe-flashplugin package the
+second most popular used package that is missing in Debian. The sixth
+most popular is flashplayer-mozilla. This is a clear indication that
+working flash is important for Debian users. Around 10 percent of the
+users submitting data to popcon.debian.org have this package
+installed.</p>
+
+<p>In the report written by Lars Risan in August 2008
+(«<a href="http://wiki.skolelinux.no/Dokumentasjon/Rapporter?action=AttachFile&do=view&target=Skolelinux_i_bruk_rapport_1.0.pdf">Skolelinux
+i bruk – Rapport for Hurum kommune, Universitetet i Agder og
+stiftelsen SLX Debian Labs</a>»), one of the most important problems
+schools experienced with <a href="http://www.skolelinux.org/">Debian
+Edu/Skolelinux</a> was the lack of working Flash. A lot of educational
+web sites require Flash to work, and lacking working Flash support in
+the web browser and the problems with installing it was perceived as a
+good reason to stay with Windows.</p>
+
+<p>I once saw a funny and sad comment in a web forum, where Linux was
+said to be the retarded cousin that did not really understand
+everything you told him but could work fairly well. This was a
+comment regarding the problems Linux have with proprietary formats and
+non-standard web pages, and is sad because it exposes a fairly common
+understanding of whose fault it is if web pages that only work in for
+example Internet Explorer 6 fail to work on Firefox, and funny because
+it explain very well how annoying it is for users when Linux
+distributions do not work with the documents they receive or the web
+pages they want to visit.</p>
+
+<p>This is part of the reason why I believe it is important for Debian
+and Debian Edu to have a well working Flash implementation in the
+distribution, to get at least popular sites as Youtube and Google
+Video to working out of the box. For Squeeze, Debian have the chance
+to include the latest version of Gnash that will make this happen, as
+the new release 0.8.8 was published a few weeks ago and is resting in
+unstable. The new version work with more sites that version 0.8.7.
+The Gnash maintainers have asked for a freeze exception, but the
+release team have not had time to reply to it yet. I hope they agree
+with me that Flash is important for the Debian desktop users, and thus
+accept the new package into Squeeze.</p>

-<p>The framework for this feature was today commited to the git
-repositry for the xorg package, and the git repository for xdm has
-been updated to use this framework. Next on my agenda is to make sure
-kdm and gdm also add code to use this framework.</p>
-
-<p>In Debian Edu, we want to ability to run commands as root when the
-user log out, to get rid of runaway processes and do general cleanup
-after a user. With this framework in place, we finally can do that in
-a generic way that work with all display managers using this
-framework. My goal is to get all display managers in Debian use it,
-similar to how they use the Xsession.d framework today.<p>
+<p>This evening I made my first Perl GUI application. The last few
+days I have worked on a Perl module for controlling my recently
+aquired Spykee robots, and the module is now getting complete enought
+that it is possible to use it to control the robot driving at least.
+It was now time to figure out how to use it to create some GUI to
+allow me to drive the robot around. I picked PerlQt as I have had
+positive experiences with the Qt API before, and spent a few minutes
+browsing the web for examples. Using Qt Designer seemed like a short
+cut, so I ended up writing the perl GUI using Qt Designer and
+compiling it into a perl program using the puic program from
+libqt-perl. Nothing fancy yet, but it got buttons to connect and
+drive around.</p>
+
+<p>The perl module I have written provide a object oriented API for
+controlling the robot. Here is an small example on how to use it:</p>
+
+<p><pre>
+use Spykee;
+Spykee::discover(sub {$robot{$_[0]} = $_[1]});
+my $host = (keys %robot)[0];
+my $spykee = Spykee->new();
+$spykee->contact($host, "admin", "admin");
+$spykee->left();
+sleep 2;
+$spykee->right();
+sleep 2;
+$spykee->forward();
+sleep 2;
+$spykee->back();
+sleep 2;
+$spykee->stop();
+</pre></p>
+
+<p>Thanks to the release of the source of the robot firmware, I could
+peek into the implementation at the other end to figure out how to
+implement the protocol used by the robot. I've implemented several of
+the commands the robot understand, but is still missing the camera
+support to make it possible to control the robot from remote. First I
+want to implement support for uploading new firmware and configuring
+the wireless network, to make it possible to bootstrap a Spykee robot
+without the producers Windows and MacOSX software (I only have Linux,
+so I had to ask a friend to come over to get the robot testing
+going. :).</p>
+
+<p>Will release the source to the public soon, but need to figure out
+where to make it available first. I will add a link to
+<a href="http://wiki.nuug.no/grupper/robot/">the NUUG wiki</a> for
+those that want to check back later to find it.</p>

-<p>Den norske bokbransjen har
-<a href="http://www.digi.no/823912/nei-til-moms-paa-e-boker">bedt om at

-<a href="http://www.digi.no/836875/moms-paa-alt-digitalt-innhold">finansdepartementet
-har sagt nei</a>. Det er et interessant spørsmål om digitale bøker
-bør ha mva-fritak eller ikke, og svaret er ikke så enkelt som et ja
-eller nei.
-<a href="http://www.digi.no/836925/norske-e-boker-truet-av-moms">Enkelte
-medlemmer</a> av bokbransjen truer med å droppe den planlagte
-lanseringen av norske digitale bøker med digitale restriksjonsmekanismer
-(DRM) som de har snakket om å gjennomføre nå i vår, og det må de
-gjerne gjøre for min del.</p>
-
-<p>Papirbøker har mva-fritak pga. at de fremmer kultur- og
-kunnskapsspredning. Digitale bøker uten digitale
-restriksjonsmekanismer (DRM) fremmer kultur- og kunnskapsspredning,
-mens digitale bøker med DRM hindrer kultur og kunnskapsspredning.
-Digitale bøker uten DRM bør få mva-fritak da det er salg av bøker på
-lik linje med salg av papirbøker, mens digitale bøker med DRM ikke bør
-få det da det er utleie av bøker og ikke salg.</p>
-
-<p>Jeg foretrekker å kjøpe bøker, og velger dermed å la være å bruke
-DRM-belastede digitale bøker. Vet ikke helt hva jeg ville være villig
-til å betale for å leie en bok, men tror ikke det er mange kronene.
-Heldigvis er det mye bøker tilgjengelig uten slike restriksjoner, og
-de som vil ha tak i engelske bøker kan laste ned bøker som er
-tilgjengelig uten bruksbegresninger fra <a href="http://www.archive.org/">The
-Internet Archive</a>. Der er det pr. i dag 1 889 313 bøker
-tilgjengelig. De er tilgjengelig i flere formater. Besøk
-<a href="http://www.archive.org/details/texts">oversikten over tekster
-der</a> for å se hva de har.
+<p>Ble tipset i dag om at et forslag om å stoppe forsøkene med

+<a href="http://www.stortinget.no/no/Saker-og-publikasjoner/Saker/Sak/?p=46616">til

-<p>On Tuesday, the Debian/Lenny based version of
-<a href="http://www.skolelinux.org/">Skolelinux</a> was finally
-shipped. This was a major leap forward for the project, and I am very
-pleased that we finally got the release wrapped up. Work on the first
-point release starts imediately, as we plan to get that one out a
-month after the major release, to include all fixes for bugs we found
-and fixed too late in the release process to include last Tuesday.</p>
-
-<p>Perhaps it even is time for some partying?</p>
-
-<p>After this first point release, my plan is to focus again on the
-next major release, based on Squeeze. We will try to get as many of
-the fixes we need into the official Debian packages before the freeze,
-and have just a few weeks or months to make it happen.</p>
+<p>Just got an email from Tobias Gruetzmacher as a followup on my
+<a href="http://people.skolelinux.org/pere/blog/Broken_umask_handling_with_sshfs.html">previous
+post about sshfs</a>. He reported another problem with sshfs. It
+fail to handle hard links properly. A simple way to spot this is to
+look at the . and .. entries in the directory tree. These should have
+a link count >1, but on sshfs the count is 1. I just tested to see
+what happen when trying to hardlink, and this fail as well:</p>
+
+<pre>
+% ln foo bar
+ln: creating hard link `bar' => `foo': Function not implemented
+%
+</pre>
+
+<p>I have not yet found time to implement a test for this in my file
+system test code, but believe having working hard links is useful to
+avoid surprised unix programs. Not as useful as working file locking
+and symlinks, which are required to get a working desktop, but useful
+nevertheless. :)</p>
+
+<p>The latest version of the file system test code is available via
+git from

-
-<p>Noe slikt burde være et krav også i Norge.</p>
+<p>Jeg skrev for et halvt år siden hvordan
+<a href="http://people.skolelinux.org/pere/blog/Sikkerhet__teater__og_hvordan_gj__re_verden_sikrere.html">samfunnet
+kaster bort ressurser på sikkerhetstiltak som ikke fungerer</a>. Kom
+nettopp over en
+<a href="http://www.askthepilot.com/essays-and-stories/terrorism-tweezers-and-terminal-madness-an-essay-on-security/">historie
+fra en pilot fra USA</a> som kommenterer det samme. Jeg mistenker det
+kun er uvitenhet og autoritetstro som gjør at så få protesterer. Har
+veldig sans for piloten omtalt i <a
+href="http://www.aftenposten.no/nyheter/iriks/article2057501.ece">Aftenposten</a> 2007-10-23,
+og skulle ønske flere rettet oppmerksomhet mot problemet. Det gir
+ikke meg trygghetsfølelse på flyplassene når jeg ser at
+flyplassadministrasjonen kaster bort folk, penger og tid på tull i
+stedet for ting som bidrar til reell økning av sikkerheten. Det
+forteller meg jo at vurderingsevnen til de som burde bidra til økt
+sikkerhet er svært sviktende, noe som ikke taler godt for de andre
+tiltakene.</p>
+
+<p>Mon tro hva som skjer hvis det fantes en enkel brosjyre å skrive ut
+fra Internet som forklarte hva som er galt med sikkerhetsopplegget på
+flyplassene, og folk skrev ut og la en bunke på flyplassene når de
+passerte. Kanskje det ville fått flere til å få øynene opp for
+problemet.</p>
+
+<p>Personlig synes jeg flyopplevelsen er blitt så avskyelig at jeg
+forsøker å klare meg med tog, bil og båt for å slippe ubehaget. Det
+er dog noe vanskelig i det langstrakte Norge og for å kunne besøke de
+delene av verden jeg ønsker å nå. Mistenker at flere har det slik, og
+at dette går ut over inntjeningen til flyselskapene. Det er antagelig
+en god ting sett fra et miljøperspektiv, men det er en annen sak.</p>

-<p>One of the new features in the next Debian/Lenny based release of
-Debian Edu/Skolelinux, which is scheduled for release in the next few
-days, is automatic configuration of the service monitoring system
-Nagios. The previous release had automatic configuration of trend
-analysis using Munin, and this Lenny based release take that a step
-further.</p>
-
-<p>When installing a Debian Edu Main-server, it is automatically
-configured as a Munin and Nagios server. In addition, it is
-configured to be a server for the
-<a href="http://wiki.debian.org/DebianEdu/HowTo/SiteSummary">SiteSummary
-system</a> I have written for use in Debian Edu. The SiteSummary
-system is inspired by a system used by the University of Oslo where I
-work. In short, the system provide a centralised collector of
-information about the computers on the network, and a client on each
-computer submitting information to this collector. This allow for
-automatic information on which packages are installed on each machine,
-which kernel the machines are using, what kind of configuration the
-packages got etc. This also allow us to automatically generate Munin
-and Nagios configuration.</p>
-
-<p>All computers reporting to the sitesummary collector with the
-munin-node package installed is automatically enabled as a Munin
-client and graphs from the statistics collected from that machine show
-up automatically on http://www/munin/ on the Main-server.</p>
-
-<p>All non-laptop computers reporting to the sitesummary collector are
-automatically monitored for network presence (ping and any network
-services detected). In addition, all computers (also laptops) with
-the nagios-nrpe-server package installed and configured the way
-sitesummary would configure it, are monitored for full disks, software
-raid status, swap free and other checks that need to run locally on
-the machine.</p>
-
-<p>The result is that the administrator on a school using Debian Edu
-based on Lenny will be able to check the health of his installation
-with one look at the Nagios settings, without having to spend any time
-keeping the Nagios configuration up-to-date.</p>
-
-<p>The only configuration one need to do to get Nagios up and running
-is to set the password used to get access via HTTP. The system
-administrator need to run "<tt>htpasswd /etc/nagios3/htpasswd.users
-nagiosadmin</tt>" to create a nagiosadmin user and set a password for
-it to be able to log into the Nagios web pages. After that,
-everything is taken care of.</p>
+<p>Denne høsten skal endelig alle Osloskolene få mulighet til å bruke
+<a href="http://www.skolelinux.org/">Skolelinux</a>. Ny IT-løsning
+har vært rullet ut i noen måneder nå, og så vidt jeg fikk vite før
+sommeren skulle alle skoler ha nytt opplegg på plass før oppstart nå i
+høst. På alle skolene skal en kunne velge ved installasjon om en skal
+ha Windows eller Skolelinux på maskinene, og en kan i tillegg
+PXE-boote maskinene over nett som tynne klienter eller diskløse
+arbeidsstasjoner. Jeg er spent på hvor mange skoler som velger å ta i
+bruk Skolelinux, og gleder meg til å se hvordan dette utvikler seg.
+Løsningen leveres av
+<a href="http://www.logica.no/">Logica</a> med
+<a href="http://www.slxdrift.no/">Skolelinux Drift AS</a> som
+underleverandør, og jeg har vært involvert i utviklingen av løsningen
+via Skolelinux Drift AS siden prosjektet starter. Jeg synes det er
+fantastisk at Skolelinux er kommet så langt siden vi startet i 2001 at
+alle elevene i Osloskolene nå skal få mulighet til å bruke
+løsningen. Jeg håper de vil sette pris på alle de
+<a href="http://www.skolelinux.no/linux-signpost/">fantastiske
+brukerprogrammene</a> som er tilgjengelig i Skolelinux.</p>
