  24   <div class="date">2010-04-28 20:40</div>
  25   <div class="body">
  26 <p>For some years now, I have wondered how we should handle laptops in
  27 Debian Edu.  The Debian Edu infrastructure is mostly designed to
  28 handle stationary computers, and less suited for computers that come
  29 and go.</p>
  30
  31 <p>Now I finally believe I have an sensible idea on how to adjust
  32 Debian Edu for laptops, by introducing a new profile for them, for
  33 example called Roaming Workstations.  Here are my thought on this.
  34 The setup would consist of the following:</p>
  35
  36 <ul>
  37
  38  <li>During installation, the user name of the owner / primary user of
  39    the laptop is requested and a local home directory is set up for
  40    the user, with uid and gid information fetched from the LDAP
  41    server.  This allow the user to work also when offline.  The
  42    central home directory can be available in a subdirectory on
  43    request, for example mounted via CIFS.  It could be mounted
  44    automatically when a user log in while on the Debian Edu network,
  45    and unmounted when the machine is taken away (network down,
  46    hibernate, etc), it can be set up to do automatic mounting on
  47    request (using autofs), or perhaps some GUI button on the desktop
  48    can be used to access it when needed.  Perhaps it is enough to use
  49    the fish protocol in KDE?</li>
  50
  51  <li>Password checking is set up to use LDAP or Kerberos
  52    authentication when the machine is on the Debian Edu network, and
  53    to cache the password for offline checking when the machine unable
  54    to reach the LDAP or Kerberos server.  This can be done using
  55    <a href="http://www.padl.com/OSS/pam_ccreds.html">libpam-ccreds</a>
  56    or the Fedora developed
  57    <a href="https://fedoraproject.org/wiki/Features/SSSD">System
  58    Security Services Daemon</a> packages.</li>
  59
  60  <li>File synchronisation with the central home directory is set up
  61    using a shared directory in both the local and the central home
  62    directory, using unison.</li>
  63
  64  <li>Printing should be set up to print to all printers broadcasting
  65    their existence on the local network, and should then work out of
  66    the box with CUPS.  For sites needing accurate printer quotas, some
  67    system with Kerberos authentication or printing via ssh could be
  68    implemented.</li>
  69
  70  <li>For users that should have local root access to their laptop,
  71    sudo should be used to allow this to the local user.</li>
  72
  73  <li>It would be nice if user and group information from LDAP is
  74    cached on the client, but given that there are entries for the
  75    local user and primary group in /etc/, it should not be needed.</li>
  76
  77 </ul>
  78
  79 <p>I believe all the pieces to implement this are in Debian/testing at
  80 the moment.  If we work quickly, we should be able to get this ready
  81 in time for the Squeeze release to freeze.  Some of the pieces need
  82 tweaking, like libpam-ccreds should get support for pam-auth-update
  83 (<a href="http://bugs.debian.org/566718">#566718</a>) and nslcd (or
  84 perhaps debian-edu-config) should get some integration code to stop
  85 its daemon when the LDAP server is unavailable to avoid long timeouts
  86 when disconnected from the net.  If we get Kerberos enabled, we need
  87 to make sure we avoid long timeouts there too.</p>
  88
  89 <p>If you want to help out with implementing this for Debian Edu,
  90 please contact us on debian-edu@lists.debian.org.</p>

 106 <p>The last few weeks i have had the pleasure of reading a
 107 thought-provoking collection of essays by Cory Doctorow, on topics
 108 touching copyright, virtual worlds, the future of man when the
 109 conscience mind can be duplicated into a computer and many more. The
 110 book titled "Content: Selected Essays on Technology, Creativity,
 111 Copyright, and the Future of the Future" is available with few
 112 restrictions on the web, for example from
 113 <a href="http://craphound.com/content/">his own site</a>. I read the
 114 epub-version from
 115 <a href="http://www.feedbooks.com/book/2883">feedbooks</a> using
 116 <a href="http://www.fbreader.org/">fbreader</a> and my N810. I

 133 <p><a href="http://www.nuug.no/aktiviteter/20100413-kerberos/">Yesterdays
 134 NUUG presentation</a> about Kerberos was inspiring, and reminded me
 135 about the need to start using Kerberos in Skolelinux.  Setting up a
 136 Kerberos server seem to be straight forward, and if we get this in
 137 place a long time before the Squeeze version of Debian freezes, we
 138 have a chance to migrate Skolelinux away from NFSv3 for the home
 139 directories, and over to an architecture where the infrastructure do
 140 not have to trust IP addresses and machines, and instead can trust
 141 users and cryptographic keys instead.</p>
 142
 143 <p>A challenge will be integration and administration.  Is there a
 144 Kerberos implementation for Debian where one can control the
 145 administration access in Kerberos using LDAP groups?  With it, the
 146 school administration will have to maintain access control using flat
 147 files on the main server, which give a huge potential for errors.</p>
 148
 149 <p>A related question I would like to know is how well Kerberos and
 150 pam-ccreds (offline password check) work together.  Anyone know?</p>
 151
 152 <p>Next step will be to use Kerberos for access control in Lwat and
 153 Nagios.  I have no idea how much work that will be to implement.  We
 154 would also need to document how to integrate with Windows AD, as such
 155 shared network will require two Kerberos realms that need to cooperate
 156 to work properly.</p>
 157
 158 <p>I believe a good start would be to start using Kerberos on the
 159 skolelinux.no machines, and this way get ourselves experience with
 160 configuration and integration.  A natural starting point would be
 161 setting up ldap.skolelinux.no as the Kerberos server, and migrate the
 162 rest of the machines from PAM via LDAP to PAM via Kerberos one at the
 163 time.</p>
 164
 165 <p>If you would like to contribute to get this working in Skolelinux,
 166 I recommend you to see the video recording from yesterdays NUUG
 167 presentation, and start using Kerberos at home.  The video show show
 168 up in a few days.</p>

 209 <p>6 years ago, as part of the Debian Edu development I am involved
 210 in, I asked for a hook in the kdm and gdm setup to run scripts as root
 211 when the user log out.  A bug was submitted against the xfree86-common
 212 package in 2004 (<a href="http://bugs.debian.org/230422">#230422</a>),
 213 and revisited every time Debian Edu was working on a new release.
 214 Today, this finally paid off.</p>
 215
 216 <p>The framework for this feature was today commited to the git
 217 repositry for the xorg package, and the git repository for xdm has
 218 been updated to use this framework.  Next on my agenda is to make sure
 219 kdm and gdm also add code to use this framework.</p>
 220
 221 <p>In Debian Edu, we want to ability to run commands as root when the
 222 user log out, to get rid of runaway processes and do general cleanup
 223 after a user.  With this framework in place, we finally can do that in
 224 a generic way that work with all display managers using this
 225 framework.  My goal is to get all display managers in Debian use it,
 226 similar to how they use the Xsession.d framework today.<p>

 242 <p>Den norske bokbransjen har
 243 <a href="http://www.digi.no/823912/nei-til-moms-paa-e-boker">bedt om at
 244 digitale bøker må få mva-fritak</a> slik papirbøker har det, og
 245 <a href="http://www.digi.no/836875/moms-paa-alt-digitalt-innhold">finansdepartementet
 246 har sagt nei</a>.  Det er et interessant spørsmål om digitale bøker
 247 bør ha mva-fritak eller ikke, og svaret er ikke så enkelt som et ja
 248 eller nei.
 249 <a href="http://www.digi.no/836925/norske-e-boker-truet-av-moms">Enkelte
 250 medlemmer</a> av bokbransjen truer med å droppe den planlagte
 251 lanseringen av norske digitale bøker med digitale restriksjonsmekanismer
 252 (DRM) som de har snakket om å gjennomføre nå i vår, og det må de
 253 gjerne gjøre for min del.</p>
 254
 255 <p>Papirbøker har mva-fritak pga. at de fremmer kultur- og
 256 kunnskapsspredning.  Digitale bøker uten digitale
 257 restriksjonsmekanismer (DRM) fremmer kultur- og kunnskapsspredning,
 258 mens digitale bøker med DRM hindrer kultur og kunnskapsspredning.
 259 Digitale bøker uten DRM bør få mva-fritak da det er salg av bøker på
 260 lik linje med salg av papirbøker, mens digitale bøker med DRM ikke bør
 261 få det da det er utleie av bøker og ikke salg.</p>
 262
 263 <p>Jeg foretrekker å kjøpe bøker, og velger dermed å la være å bruke
 264 DRM-belastede digitale bøker.  Vet ikke helt hva jeg ville være villig
 265 til å betale for å leie en bok, men tror ikke det er mange kronene.
 266 Heldigvis er det mye bøker tilgjengelig uten slike restriksjoner, og
 267 de som vil ha tak i engelske bøker kan laste ned bøker som er
 268 tilgjengelig uten bruksbegresninger fra <a href="http://www.archive.org/">The
 269 Internet Archive</a>. Der er det pr. i dag 1 889 313 bøker
 270 tilgjengelig. De er tilgjengelig i flere formater. Besøk

 296 <p>Perhaps it even is time for some partying?</p>
 297
 298 <p>After this first point release, my plan is to focus again on the

 347   <div class="body">
 348 <p>One of the new features in the next Debian/Lenny based release of
 349 Debian Edu/Skolelinux, which is scheduled for release in the next few
 350 days, is automatic configuration of the service monitoring system
 351 Nagios.  The previous release had automatic configuration of trend
 352 analysis using Munin, and this Lenny based release take that a step
 353 further.</p>
 354
 355 <p>When installing a Debian Edu Main-server, it is automatically
 356 configured as a Munin and Nagios server.  In addition, it is
 357 configured to be a server for the
 358 <a href="http://wiki.debian.org/DebianEdu/HowTo/SiteSummary">SiteSummary
 359 system</a> I have written for use in Debian Edu.  The SiteSummary
 360 system is inspired by a system used by the University of Oslo where I
 361 work.  In short, the system provide a centralised collector of
 362 information about the computers on the network, and a client on each
 363 computer submitting information to this collector.  This allow for
 364 automatic information on which packages are installed on each machine,
 365 which kernel the machines are using, what kind of configuration the
 366 packages got etc.  This also allow us to automatically generate Munin
 367 and Nagios configuration.</p>
 368
 369 <p>All computers reporting to the sitesummary collector with the
 370 munin-node package installed is automatically enabled as a Munin
 371 client and graphs from the statistics collected from that machine show
 372 up automatically on http://www/munin/ on the Main-server.</p>
 373
 374 <p>All non-laptop computers reporting to the sitesummary collector are
 375 automatically monitored for network presence (ping and any network
 376 services detected).  In addition, all computers (also laptops) with
 377 the nagios-nrpe-server package installed and configured the way
 378 sitesummary would configure it, are monitored for full disks, software
 379 raid status, swap free and other checks that need to run locally on
 380 the machine.</p>
 381
 382 <p>The result is that the administrator on a school using Debian Edu
 383 based on Lenny will be able to check the health of his installation
 384 with one look at the Nagios settings, without having to spend any time
 385 keeping the Nagios configuration up-to-date.</p>
 386
 387 <p>The only configuration one need to do to get Nagios up and running
 388 is to set the password used to get access via HTTP.  The system
 389 administrator need to run "<tt>htpasswd /etc/nagios3/htpasswd.users
 390 nagiosadmin</tt>" to create a nagiosadmin user and set a password for
 391 it to be able to log into the Nagios web pages.  After that,
 392 everything is taken care of.</p>
