  15 &lt;p&gt;The last few weeks i have had the pleasure of reading a
  16 thought-provoking collection of essays by Cory Doctorow, on topics
  17 touching copyright, virtual worlds, the future of man when the
  18 conscience mind can be duplicated into a computer and many more. The
  19 book titled &quot;Content: Selected Essays on Technology, Creativity,
  20 Copyright, and the Future of the Future&quot; is available with few
  21 restrictions on the web, for example from
  22 &lt;a href=&quot;http://craphound.com/content/&quot;&gt;his own site&lt;/a&gt;. I read the
  23 epub-version from
  24 &lt;a href=&quot;http://www.feedbooks.com/book/2883&quot;&gt;feedbooks&lt;/a&gt; using
  25 &lt;a href=&quot;http://www.fbreader.org/&quot;&gt;fbreader&lt;/a&gt; and my N810. I
  26 strongly recommend this book.&lt;/p&gt;

  36 &lt;p&gt;&lt;a href=&quot;http://www.nuug.no/aktiviteter/20100413-kerberos/&quot;&gt;Yesterdays
  37 NUUG presentation&lt;/a&gt; about Kerberos was inspiring, and reminded me
  38 about the need to start using Kerberos in Skolelinux.  Setting up a
  39 Kerberos server seem to be straight forward, and if we get this in
  40 place a long time before the Squeeze version of Debian freezes, we
  41 have a chance to migrate Skolelinux away from NFSv3 for the home
  42 directories, and over to an architecture where the infrastructure do
  43 not have to trust IP addresses and machines, and instead can trust
  44 users and cryptographic keys instead.&lt;/p&gt;
  45
  46 &lt;p&gt;A challenge will be integration and administration.  Is there a
  47 Kerberos implementation for Debian where one can control the
  48 administration access in Kerberos using LDAP groups?  With it, the
  49 school administration will have to maintain access control using flat
  50 files on the main server, which give a huge potential for errors.&lt;/p&gt;
  51
  52 &lt;p&gt;A related question I would like to know is how well Kerberos and
  53 pam-ccreds (offline password check) work together.  Anyone know?&lt;/p&gt;
  54
  55 &lt;p&gt;Next step will be to use Kerberos for access control in Lwat and
  56 Nagios.  I have no idea how much work that will be to implement.  We
  57 would also need to document how to integrate with Windows AD, as such
  58 shared network will require two Kerberos realms that need to cooperate
  59 to work properly.&lt;/p&gt;
  60
  61 &lt;p&gt;I believe a good start would be to start using Kerberos on the
  62 skolelinux.no machines, and this way get ourselves experience with
  63 configuration and integration.  A natural starting point would be
  64 setting up ldap.skolelinux.no as the Kerberos server, and migrate the
  65 rest of the machines from PAM via LDAP to PAM via Kerberos one at the
  66 time.&lt;/p&gt;
  67
  68 &lt;p&gt;If you would like to contribute to get this working in Skolelinux,
  69 I recommend you to see the video recording from yesterdays NUUG
  70 presentation, and start using Kerberos at home.  The video show show
  71 up in a few days.&lt;/p&gt;

  81 &lt;p&gt;&lt;a href=&quot;http://fotball.aftenposten.no/incoming/article163000.ece&quot;&gt;Aftenposten
  82 melder&lt;/a&gt; på forsiden av webavisen sin at de tror Erling Fossen
  83 provoserer nordlendinger med sine uttalelser på
  84 fotballtinget.  Jeg er utflyttet nordlending, og må innrømme at jeg
  85 ikke kjennet så mye som et snev av provokasjon fra denne litt morsomme
  86 uttalelsen til Hr. Fossen.  Lurer på om Aftenposten har noen kilder
  87 utenom redaksjonen for sin påstand om at nordledinger er provosert av
  88 Hr. Fossen.  Må innrømme at jeg tviler på det.&lt;/p&gt;
  89
  90 &lt;p&gt;Det hele bringer tankene tilbake til Sture Hansen i Hallo i Uken.&lt;/p&gt;

 100 &lt;p&gt;6 years ago, as part of the Debian Edu development I am involved
 101 in, I asked for a hook in the kdm and gdm setup to run scripts as root
 102 when the user log out.  A bug was submitted against the xfree86-common
 103 package in 2004 (&lt;a href=&quot;http://bugs.debian.org/230422&quot;&gt;#230422&lt;/a&gt;),
 104 and revisited every time Debian Edu was working on a new release.
 105 Today, this finally paid off.&lt;/p&gt;
 106
 107 &lt;p&gt;The framework for this feature was today commited to the git
 108 repositry for the xorg package, and the git repository for xdm has
 109 been updated to use this framework.  Next on my agenda is to make sure
 110 kdm and gdm also add code to use this framework.&lt;/p&gt;
 111
 112 &lt;p&gt;In Debian Edu, we want to ability to run commands as root when the
 113 user log out, to get rid of runaway processes and do general cleanup
 114 after a user.  With this framework in place, we finally can do that in
 115 a generic way that work with all display managers using this
 116 framework.  My goal is to get all display managers in Debian use it,
 117 similar to how they use the Xsession.d framework today.&lt;p&gt;

 127 &lt;p&gt;Den norske bokbransjen har
 128 &lt;a href=&quot;http://www.digi.no/823912/nei-til-moms-paa-e-boker&quot;&gt;bedt om at
 129 digitale bøker må få mva-fritak&lt;/a&gt; slik papirbøker har det, og
 130 &lt;a href=&quot;http://www.digi.no/836875/moms-paa-alt-digitalt-innhold&quot;&gt;finansdepartementet
 131 har sagt nei&lt;/a&gt;.  Det er et interessant spørsmål om digitale bøker
 132 bør ha mva-fritak eller ikke, og svaret er ikke så enkelt som et ja
 133 eller nei.
 134 &lt;a href=&quot;http://www.digi.no/836925/norske-e-boker-truet-av-moms&quot;&gt;Enkelte
 135 medlemmer&lt;/a&gt; av bokbransjen truer med å droppe den planlagte
 136 lanseringen av norske digitale bøker med digitale restriksjonsmekanismer
 137 (DRM) som de har snakket om å gjennomføre nå i vår, og det må de
 138 gjerne gjøre for min del.&lt;/p&gt;
 139
 140 &lt;p&gt;Papirbøker har mva-fritak pga. at de fremmer kultur- og
 141 kunnskapsspredning.  Digitale bøker uten digitale
 142 restriksjonsmekanismer (DRM) fremmer kultur- og kunnskapsspredning,
 143 mens digitale bøker med DRM hindrer kultur og kunnskapsspredning.
 144 Digitale bøker uten DRM bør få mva-fritak da det er salg av bøker på
 145 lik linje med salg av papirbøker, mens digitale bøker med DRM ikke bør
 146 få det da det er utleie av bøker og ikke salg.&lt;/p&gt;
 147
 148 &lt;p&gt;Jeg foretrekker å kjøpe bøker, og velger dermed å la være å bruke
 149 DRM-belastede digitale bøker.  Vet ikke helt hva jeg ville være villig
 150 til å betale for å leie en bok, men tror ikke det er mange kronene.
 151 Heldigvis er det mye bøker tilgjengelig uten slike restriksjoner, og
 152 de som vil ha tak i engelske bøker kan laste ned bøker som er
 153 tilgjengelig uten bruksbegresninger fra &lt;a href=&quot;http://www.archive.org/&quot;&gt;The
 154 Internet Archive&lt;/a&gt;. Der er det pr. i dag 1 889 313 bøker
 155 tilgjengelig. De er tilgjengelig i flere formater. Besøk
 156 &lt;a href=&quot;http://www.archive.org/details/texts&quot;&gt;oversikten over tekster
 157 der&lt;/a&gt; for å se hva de har.

 167 &lt;p&gt;On Tuesday, the Debian/Lenny based version of
 168 &lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt; was finally
 169 shipped.  This was a major leap forward for the project, and I am very
 170 pleased that we finally got the release wrapped up.  Work on the first
 171 point release starts imediately, as we plan to get that one out a
 172 month after the major release, to include all fixes for bugs we found
 173 and fixed too late in the release process to include last Tuesday.&lt;/p&gt;
 174
 175 &lt;p&gt;Perhaps it even is time for some partying?&lt;/p&gt;
 176
 177 &lt;p&gt;After this first point release, my plan is to focus again on the
 178 next major release, based on Squeeze.  We will try to get as many of
 179 the fixes we need into the official Debian packages before the freeze,
 180 and have just a few weeks or months to make it happen.&lt;/p&gt;

 190 &lt;p&gt;Ble nettopp gjort oppmerksom på en
 191 &lt;a href=&quot;http://www.version2.dk/artikel/13690-breaking-odf-vinder-dokumentformat-krigen &quot;&gt;nyhet fra Version2&lt;/a&gt;
 192 fra Danmark, der det hevdes at Folketinget har vedtatt at ODF skal
 193 brukes som dokumentutvekslingsformat i Staten.&lt;/p&gt;
 194
 195 &lt;p&gt;Hyggelig lesning, spesielt hvis det viser seg at de av vedtatt
 196 kravlisten for hva som skal aksepteres som referert i kommentarfeltet
 197 til artikkelen og

 200
 201 &lt;p&gt;&lt;blockquote&gt; Det skal demonstreres, at standarden i sin helhed kan
 202 implementeres af alle direkte i sin helhed på flere
 203 platforme.&lt;/blockquote&gt;&lt;/p&gt;

 215 &lt;p&gt;One of the new features in the next Debian/Lenny based release of
 216 Debian Edu/Skolelinux, which is scheduled for release in the next few
 217 days, is automatic configuration of the service monitoring system
 218 Nagios.  The previous release had automatic configuration of trend
 219 analysis using Munin, and this Lenny based release take that a step
 220 further.&lt;/p&gt;
 221
 222 &lt;p&gt;When installing a Debian Edu Main-server, it is automatically
 223 configured as a Munin and Nagios server.  In addition, it is
 224 configured to be a server for the
 225 &lt;a href=&quot;http://wiki.debian.org/DebianEdu/HowTo/SiteSummary&quot;&gt;SiteSummary
 226 system&lt;/a&gt; I have written for use in Debian Edu.  The SiteSummary
 227 system is inspired by a system used by the University of Oslo where I
 228 work.  In short, the system provide a centralised collector of
 229 information about the computers on the network, and a client on each
 230 computer submitting information to this collector.  This allow for
 231 automatic information on which packages are installed on each machine,
 232 which kernel the machines are using, what kind of configuration the
 233 packages got etc.  This also allow us to automatically generate Munin
 234 and Nagios configuration.&lt;/p&gt;
 235
 236 &lt;p&gt;All computers reporting to the sitesummary collector with the
 237 munin-node package installed is automatically enabled as a Munin
 238 client and graphs from the statistics collected from that machine show
 239 up automatically on http://www/munin/ on the Main-server.&lt;/p&gt;
 240
 241 &lt;p&gt;All non-laptop computers reporting to the sitesummary collector are
 242 automatically monitored for network presence (ping and any network
 243 services detected).  In addition, all computers (also laptops) with
 244 the nagios-nrpe-server package installed and configured the way
 245 sitesummary would configure it, are monitored for full disks, software
 246 raid status, swap free and other checks that need to run locally on
 247 the machine.&lt;/p&gt;
 248
 249 &lt;p&gt;The result is that the administrator on a school using Debian Edu
 250 based on Lenny will be able to check the health of his installation
 251 with one look at the Nagios settings, without having to spend any time
 252 keeping the Nagios configuration up-to-date.&lt;/p&gt;
 253
 254 &lt;p&gt;The only configuration one need to do to get Nagios up and running
 255 is to set the password used to get access via HTTP.  The system
 256 administrator need to run &quot;&lt;tt&gt;htpasswd /etc/nagios3/htpasswd.users
 257 nagiosadmin&lt;/tt&gt;&quot; to create a nagiosadmin user and set a password for
 258 it to be able to log into the Nagios web pages.  After that,
 259 everything is taken care of.&lt;/p&gt;

 289 &lt;p&gt;De færreste er klar over at Skolelinux-prosjektet kom som et resultat
 290 av en avgjørelse på årsmøtet i
 291 &lt;a href=&quot;http://www.nuug.no/&quot;&gt;NUUG&lt;/a&gt; i 2000-06-29, der Håkon Wium
 292 Lie, da varamedlem i styret, tok på seg oppdraget om å starte et
 293 initiativ kalt &quot;Teach the Teacher&quot;, som skulle være et initiativ for
 294 å få fri programvare og unix-lignende operativsystemer inn i Skolen.
 295 Tanken var at en måtte starte med lærerne for at ungene skulle få
 296 mulighet til å møte en bedre IT-hverdag.  Jeg var tilstede på
 297 møtet, og hadde sans for ideen, men intet skjedde.  På vårparten
 298 2001 ble det arrangert en demonstrasjon i anledning at First Tuesday
 299 hadde invitert Microsoft til et møte for å fortelle om fremtidens
 300 Internet.  Dette provoserte endel av oss, og EFN og NUUG tok initiativ
 301 til å arrangere
 302 &lt;a href=&quot;http://www.digi.no/60982/first-tuesday-mote-med-microsoft-protest&quot;&gt;en
 303 demonstrasjon utenfor lokalene 2001-05-21&lt;/a&gt;.  Blant de som sto bak
 304 demonstrasjonen var Vidar Bakke fra NUUG og Håkon W. Lie fra EFN.
 305 Etter demonstrasjonen arrangerte Håkon en fest hjemme hos seg der alle
 306 som hadde vært aktive i demonstrasjonsplanlegging og gjennomføringen
 307 deltok.  Før festen var jeg blitt lei av å vente på at Håkon skulle ta
 308 initiativ til &quot;Teach the Teacher&quot;, og for å forsøke å få litt fremgang
 309 besteme jeg meg for å benytte anledningen hos Håkon til å snakke om
 310 behovet for å hjelpe skolene i gang med bedre datasystemer bestående
 311 av fri programvare og unix-lignende operativsystemer.  Flere var
 312 interessert, og Knut Yrvin tenkte på ideen.  Han
 313 &lt;a href=&quot;http://developer.skolelinux.no/brev/2001-06-28-invitasjon-skolelinux.txt&quot;&gt;ropte
 314 sammen&lt;/a&gt; til et stiftelsesmøte i prosjektet i sin arbeidsgivers
 315 Objectwares lokaler ved Ullevål stadion 2001-07-02, og jeg ble med.
 316 Resten er historie. :)&lt;/p&gt;
