<div class="body">
-<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>
+<p>The last few days I have done some upgrade testing in Debian, to
+see if the upgrade from Lenny to Squeeze will go smoothly. A few bugs
+have been discovered and reported in the process
+(<a href="http://bugs.debian.org/585410">#585410</a> in nagios3-cgi,
+<a href="http://bugs.debian.org/584879">#584879</a> already fixed in
+enscript and <a href="http://bugs.debian.org/584861">#584861</a> in
+kdebase-workspace-data), and to get a more regular testing going on, I
+am working on a script to automate the test.</p>
+
+<p>The idea is to create a Lenny chroot and use tasksel to install a
+Gnome or KDE desktop installation inside the chroot before upgrading
+it. To ensure no services are started in the chroot, a policy-rc.d
+script is inserted. To make sure tasksel believe it is to install a
+desktop on a laptop, the tasksel tests are replaced in the chroot
+(only acceptable because this is a throw-away chroot).</p>
+
+<p>A naive upgrade from Lenny to Squeeze using aptitude dist-upgrade
+currently always fail because udev refuses to upgrade with the kernel
+in Lenny, so to avoid that problem the file /etc/udev/kernel-upgrade
+is created. The bug report
+<a href="http://bugs.debian.org/566000">#566000</a> make me suspect
+this problem do not trigger in a chroot, but I touch the file anyway
+to make sure the upgrade go well. Testing on virtual and real
+hardware have failed me because of udev so far, and creating this file
+do the trick in such settings anyway. This is a
+<a href="http://www.linuxquestions.org/questions/debian-26/failed-dist-upgrade-due-to-udev-config_sysfs_deprecated-nonsense-804130/">known
+issue</a> and the current udev behaviour is intended by the udev
+maintainer because he lack the resources to rewrite udev to keep
+working with old kernels or something like that. I really wish the
+udev upstream would keep udev backwards compatible, to avoid such
+upgrade problem, but given that they fail to do so, I guess
+documenting the way out of this mess is the best option we got for
+Debian Squeeze.</p>
+
+<p>Anyway, back to the task at hand, testing upgrades. This test
+script, which I call <tt>upgrade-test</tt> for now, is doing the
+trick:</p>
<blockquote><pre>

-<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>I suspect it would be useful to test upgrades with both apt-get and
+with aptitude, but I have not had time to look at how they behave
+differently so far. I hope to get a cron job running to do the test
+regularly and post the result on the web. The Gnome upgrade currently
+work, while the KDE upgrade fail because of the bug in
+kdebase-workspace-data</p>
+
+<p>I am not quite sure what kind of extract from the huge upgrade logs
+(KDE 167 KiB, Gnome 516 KiB) it make sense to include in this blog
+post, so I will refrain from trying. I can report that for Gnome,
+aptitude report 760 packages upgraded, 448 newly installed, 129 to
+remove and 1 not upgraded and 1024MB need to be downloaded while for
+KDE the same numbers are 702 packages upgraded, 507 newly installed,
+193 to remove and 0 not upgraded and 1117MB need to be downloaded</p>
+
+<p>I am very happy to notice that the Gnome desktop + laptop upgrade
+is able to migrate to dependency based boot sequencing and parallel
+booting without a hitch. Was unsure if there were still bugs with
+packages failing to clean up their obsolete init.d script during
+upgrades, and no such problem seem to affect the Gnome desktop+laptop
+packages.</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>Det er merkelig hvordan myter om Skolelinux overlever. En slik
+myte er at Skolelinux ikke kan sentraldriftes og ha sentralt plasserte
+tjenermaskiner. I siste Computerworld Norge er
+<a href="http://www.idg.no/computerworld/article169432.ece">IT-sjef
+Viggo Billdal i Steinkjer intervjuet</a>, og forteller uten
+blygsel:</p>
+
+<blockquote><p>Vi hadde Skolelinux, men det har vi sluttet med. Vi testet
+om det lønte seg med Microsoft eller en åpen plattform. Vi fant ut at
+Microsoft egentlig var totalt sett bedre egnet. Det var store
+driftskostnader med Skolelinux, blant annet på grunn av
+desentraliserte servere. Det var komplisert, så vi gikk vekk fra det
+og bruker nå bare Windows.</p></blockquote>
+
+<p>En <a
+href="https://init.linpro.no/pipermail/skolelinux.no/bruker/2010-June/009101.html">rask
+sjekk</a> mot den norske brukerlista i Skolelinuxprosjektet forteller
+at Steinkjers forsøk foregikk fram til 2004/2005, og at Røysing skole
+i Steinkjer skal ha vært svært fornøyd med Skolelinux men at kommunen
+overkjørte skolen og krevde at de gikk over til Windows. Et søk på
+nettet sendte meg til
+<a href="http://www.dn.no/multimedia/archive/00090/Dagens_it_nr__18_90826a.pdf">Dagens
+IT nr. 18 2005</a> hvor en kan lese på side 18:</p>
+
+<blockquote><p>Inge Tømmerås ved Røysing skole i Steinkjer kjører ennå
+Microsoft, men forteller at kompetanseutfordringen med Skolelinux ikke
+var så stor. Jeg syntes Skolelinux var utrolig lett å drifte uten
+forkunnskaper. Men man må jo selvsagt ha tilgang på ekstern kompetanse
+til installasjoner og maskinvarefeil, sier Tømmerås.</p></blockquote>
+
+<p>Som systemarkitekten bak Skolelinux, kan jeg bare riste på hodet
+over påstanden om at Skolelinux krever desentraliserte tjenere.
+Skolelinux-arkitekturen er laget for sentralisert drift og plassering
+av tjenerne lokalt eller sentralt alt etter behov og nettkapasitet.
+Den er modellert på nettverks- og tjenerløsningen som brukes på
+Universitetet i Tromsø og Oslo, der jeg jobber med utvikling av
+driftstjenester. Dette er det heldigvis noen som har fått med seg, og
+jeg er glad for å kunne sitere fra en kommentar på den overnevnte
+artikkelen. Min venn og gamle kollega Sturle Sunde forteller der:
+
+<blockquote>
+<p>I Flora kommune køyrer vi Skulelinux på skular med alt frå 15 til
+meir enn 500 elevar. Dei store skulane har eigen tenar, for det er
+mest praktisk. Eg, som er driftsansvarleg for heile nettet, ser
+sjeldan dei tenarane fysisk, men at dei står der gjer skulane mindre
+avhengige av eksterne linjer som er trege eller dyre. Dei minste
+skulane har ikkje eigen tenar. Å bruke sentral tenar er heller ikkje
+noko problem. Småskulane klarar seg fint med 1 mbit-linje til ein
+sentral tenar eller tenaren på ein større skule.</p>
+
+<p>Det beste med Skulelinux er halvtjukke klientar. Dei treng ikkje
+harddisk og brukar minimalt med ressursar på tenaren fordi dei køyrer
+programma lokalt. Eit klasserom med 30 sju-åtte år gamle maskiner har
+mykje meir CPU og RAM totalt enn nokon moderne tenar til under
+millionen. Det trengst to kommandoar på den sentrale tenaren for å
+oppdatere alle klientane, både tynne og halvtjukke. Vi har ingen
+problem med diskar som ryk heller, som var eit problem før fordi
+elevane sat og sparka i maskinene. Og dei krev lite bandbreidde i
+nettet, so det er fullt mogleg å køyre slike på småskular med trege
+linjer mot tenaren på ein større skule.</p>
+
+<p>Flora kommune har nesten 800 Linux-maskiner i sitt skulenett, og
+ein person som tek seg av drift av heile nettet, inkludert tenarar,
+klientar, operativsystem, programvare, heimekontorløysing og
+administrasjon av brukarar.</p>
+
+<p>No skal det seiast at vi ikkje køyrer rein Skulelinux ut av
+boksen. Vi har gjort ein del tilpassingar mot noko Novell-greier som
+var der frå før, og som har komplisert installasjonen vår. Etter at
+oppsettet var gjort har løysinga vore stabil og kravd minimalt med
+arbeid.</p>
+</blockquote>
+
+<p>Jeg vet at Narvik, Harstad og Oslo er kommuner der Skolelinux
+sentraldriftes med sentrale tjenere. Det forteller meg at Steinkjers
+IT-sjef neppe bør skylde på Skolelinux-løsningen for sine 5 år gamle
+minner.</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>If Debian is to migrate to upstart on Linux, I expect some init.d
+scripts to migrate (some of) their operations to upstart job while
+keeping the init.d for hurd and kfreebsd. The packages with such
+needs will need a way to get their init.d scripts to behave
+differently when used with sysvinit and with upstart. Because of
+this, I had a look at the environment variables set when a init.d
+script is running under upstart, and when it is not.</p>
+
+<p>With upstart, I notice these environment variables are set when a
+script is started from rcS.d/ (ignoring some irrelevant ones like
+COLUMNS):</p>
+
+<blockquote><pre>
+DEFAULT_RUNLEVEL=2
+previous=N
+PREVLEVEL=
+RUNLEVEL=
+runlevel=S
+UPSTART_EVENTS=startup
+UPSTART_INSTANCE=
+UPSTART_JOB=rc-sysinit
+</pre></blockquote>
+
+<p>With sysvinit, these environment variables are set for the same
+script.</p>
+
+<blockquote><pre>
+INIT_VERSION=sysvinit-2.88
+previous=N
+PREVLEVEL=N
+RUNLEVEL=S
+runlevel=S
+</pre></blockquote>
+
+<p>The RUNLEVEL and PREVLEVEL environment variables passed on from
+sysvinit are not set by upstart. Not sure if it is intentional or not
+to not be compatible with sysvinit in this regard.</p>
+
+<p>For scripts needing to behave differently when upstart is used,
+looking for the UPSTART_JOB environment variable seem to be a good
+choice.</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>Via the
+<a href="http://feedproxy.google.com/~r/robweir/antic-atom/~3/QzU4RgoAGMg/weekly-links-10.html">blog
+of Rob Weir</a> I came across the very interesting essay named
+<a href="http://faculty.haas.berkeley.edu/shapiro/wars.pdf">The Art of
+Standards Wars</a> (PDF 25 pages). I recommend it for everyone
+following the standards wars of today.</p>

+to get a list of the machine types in use thanks to the DMI
+information extracted from each machine. The script to do so is
+included in the sitesummary package, and here is example output from
+the Skolelinux build servers:</p>
+
+<blockquote><pre>
+maintainer:~# /usr/lib/sitesummary/hardware-model-summary
+ vendor count
+ Dell Computer Corporation 1
+ PowerEdge 1750 1
+ IBM 1
+ eserver xSeries 345 -[8670M1X]- 1
+ Intel 2
+ [no-dmi-info] 3
+maintainer:~#
+</pre></blockquote>
+
+<p>The quality of the report depend on the quality of the DMI tables
+provided in each machine. Here there are Intel machines without model
+information listed with Intel as vendor and mo model, and virtual Xen
+machines listed as [no-dmi-info]. One can add -l as a command line
+option to list the individual machines.</p>
+
+<p>A larger list is
+<a href="http://narvikskolen.no/sitesummary/">available from the the
+city of Narvik</a>, which uses Skolelinux on all their shools and also
+provide the basic sitesummary report publicly. In their report there
+are ~1400 machines. I know they use both Ubuntu and Skolelinux on
+their machines, and as sitesummary is available in both distributions,
+it is trivial to get all of them to report to the same central
+collector.</p>

-<p>6 years ago, as part of the Debian Edu development I am involved
-in, I asked for a hook in the kdm and gdm setup to run scripts as root
-when the user log out. A bug was submitted against the xfree86-common
-package in 2004 (<a href="http://bugs.debian.org/230422">#230422</a>),
-and revisited every time Debian Edu was working on a new release.
-Today, this finally paid off.</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>Det står dårlig til med toget når en finner på å la det
+<a href="http://www.aftenposten.no/nyheter/iriks/article3677060.ece">kappkjøre
+med sykkel</a>... Jeg tror det trengs strukturendringer for å få
+fikset på togproblemene i Norge.</p>
+
+<p>Mon tro hva toglinje mellom Narvik og Tromsø ville hatt slags
+effekt på området der?</p>

+<p>It is strange to watch how a bug in Debian causing KDM to fail to
+start at boot when an NVidia video card is used is handled. The
+problem seem to be that the nvidia X.org driver uses a long time to
+initialize, and this duration is longer than kdm is configured to
+wait.</p>
+
+<p>I came across two bugs related to this issue,
+<a href="http://bugs.debian.org/583312">#583312</a> initially filed
+against initscripts and passed on to nvidia-glx when it became obvious
+that the nvidia drivers were involved, and
+<a href="http://bugs.debian.org/524751">#524751</a> initially filed against
+kdm and passed on to src:nvidia-graphics-drivers for unknown reasons.</p>
+
+<p>To me, it seem that no-one is interested in actually solving the
+problem nvidia video card owners experience and make sure the Debian
+distribution work out of the box for these users. The nvidia driver
+maintainers expect kdm to be set up to wait longer, while kdm expect
+the nvidia driver maintainers to fix the driver to start faster, and
+while they wait for each other I guess the users end up switching to a
+distribution that work for them. I have no idea what the solution is,
+but I am pretty sure that waiting for each other is not it.</p>
+
+<p>I wonder why we end up handling bugs this way.</p>

<div class="body">
-<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>A few days ago, parallel booting was enabled in Debian/testing.
+The feature seem to hold up pretty well, but three fairly serious
+issues are known and should be solved:
+
+<p><ul>
+
+<li>The wicd package seen to
+<a href="http://bugs.debian.org/508289">break NFS mounting</a> and
+<a href="http://bugs.debian.org/581586">network setup</a> when
+parallel booting is enabled. No idea why, but the wicd maintainer
+seem to be on the case.</li>
+
+<li>The nvidia X driver seem to
+<a href="http://bugs.debian.org/583312">have a race condition</a>
+triggered more easily when parallel booting is in effect. The
+maintainer is on the case.</li>
+
+<li>The sysv-rc package fail to properly enable dependency based boot
+sequencing (the shutdown is broken) when old file-rc users
+<a href="http://bugs.debian.org/575080">try to switch back</a> to
+sysv-rc. One way to solve it would be for file-rc to create
+/etc/init.d/.legacy-bootordering, and another is to try to make
+sysv-rc more robust. Will investigate some more and probably upload a
+workaround in sysv-rc to help those trying to move from file-rc to
+sysv-rc get a working shutdown.</li>
+
+</ul></p>
+
+<p>All in all not many surprising issues, and all of them seem
+solvable before Squeeze is released. In addition to these there are
+some packages with bugs in their dependencies and run level settings,
+which I expect will be fixed in a reasonable time span.</p>
+
+<p>If you report any problems with dependencies in init.d scripts to
+the BTS, please usertag the report to get it to show up at
+<a href="http://bugs.debian.org/cgi-bin/pkgreport.cgi?users=initscripts-ng-devel@lists.alioth.debian.org">the
+list of usertagged bugs related to this</a>.</p>
+
+<p>Update: Correct bug number to file-rc issue.</p>

+<p>After a long break from debian-installer development, I finally
+found time today to return to the project. Having to spend less time
+working dependency based boot in debian, as it is almost complete now,
+definitely helped freeing some time.</p>
+
+<p>A while back, I ran into a problem while working on Debian Edu. We
+include some firmware packages on the Debian Edu CDs, those needed to
+get disk and network controllers working. Without having these
+firmware packages available during installation, it is impossible to
+install Debian Edu on the given machine, and because our target group
+are non-technical people, asking them to provide firmware packages on
+an external medium is a support pain. Initially, I expected it to be
+enough to include the firmware packages on the CD to get
+debian-installer to find and use them. This proved to be wrong.
+Next, I hoped it was enough to symlink the relevant firmware packages
+to some useful location on the CD (tried /cdrom/ and
+/cdrom/firmware/). This also proved to not work, and at this point I
+found time to look at the debian-installer code to figure out what was
+going to work.</p>
+
+<p>The firmware loading code is in the hw-detect package, and a closer
+look revealed that it would only look for firmware packages outside
+the installation media, so the CD was never checked for firmware
+packages. It would only check USB sticks, floppies and other
+"external" media devices. Today I changed it to also look in the
+/cdrom/firmware/ directory on the mounted CD or DVD, which should
+solve the problem I ran into with Debian edu. I also changed it to
+look in /firmware/, to make sure the installer also find firmware
+provided in the initrd when booting the installer via PXE, to allow us
+to provide the same feature in the PXE setup included in Debian
+Edu.</p>
+
+<p>To make sure firmware deb packages with a license questions are not
+activated without asking if the license is accepted, I extended
+hw-detect to look for preinst scripts in the firmware packages, and
+run these before activating the firmware during installation. The
+license question is asked using debconf in the preinst, so this should
+solve the issue for the firmware packages I have looked at so far.</p>
+
+<p>If you want to discuss the details of these features, please
+contact us on debian-boot@lists.debian.org.</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>For en stund tilbake kjøpte jeg en magnetkortleser for å kunne
+titte på hva som er skrevet inn på magnetstripene til ulike kort. Har
+ikke hatt tid til å analysere mange kort så langt, men tenkte jeg
+skulle dele innholdet på to kort med mine lesere.</p>
+
+<p>For noen dager siden tok jeg flyet til Harstad og Hurtigruten til
+Bergen. Flytoget fra Oslo S til flyplassen ga meg en billett med

+Aner ikke hva innholdet representerer, og det er lite overlapp mellom
+det jeg ser trykket på billetten og det jeg ser av tegn i
+magnetstripen. Håper det betyr at de bruker kryptografiske metoder
+for å gjøre det vanskelig å forfalske billetter.</p>
+
+<p>Den andre billetten er fra Hurtigruten, der jeg mistenker at
+strekkoden på fronten er mer brukt enn magnetstripen (det var i hvert
+fall den biten vi stakk inn i dørlåsen).</p>
