  26 <p>These days, the init.d script dependencies in Squeeze are quite
  27 complete, so complete that it is actually possible to run all the
  28 init.d scripts in parallell based on these dependencies.  If you want
  29 to test your Squeeze system, make sure
  30 <a href="http://wiki.debian.org/LSBInitScripts/DependencyBasedBoot">dependency
  31 based boot sequencing</a> is enabled, and add this line to
  32 /etc/default/rcS:</p>
  33
  34 <blockquote><pre>
  35 CONCURRENCY=makefile
  36 </pre></blockquote>
  37
  38 <p>That is it.  It will cause sysv-rc to use the startpar tool to run
  39 scripts in parallel using the dependency information stored in
  40 /etc/init.d/.depend.boot, /etc/init.d/.depend.start and
  41 /etc/init.d/.depend.stop to order the scripts.  Startpar is configured
  42 to try to start the kdm and gdm scripts as early as possible, and will
  43 start the facilities required by kdm or gdm as early as possible to
  44 make this happen.</p>
  45
  46 <p>Give it a try, and see if you like the result.  If some services
  47 fail to start properly, it is most likely because they have incomplete
  48 init.d script dependencies in their startup script (or some of their
  49 dependent scripts have incomplete dependencies).  Report bugs and get
  50 the package maintainers to fix it. :)</p>
  51
  52 <p>Running scripts in parallel could be the default in Debian when we
  53 manage to get the init.d script dependencies complete and correct.  I
  54 expect we will get there in Squeeze+1, if we get manage to test and
  55 fix the remaining issues.</p>
  56
  57 <p>If you report any problems with dependencies in init.d scripts to
  58 the BTS, please usertag the report to get it to show up at
  59 <a href="http://bugs.debian.org/cgi-bin/pkgreport.cgi?users=initscripts-ng-devel@lists.alioth.debian.org">the

  75   <div class="body">
  76 <p>One interesting feature in Active Directory, is the ability to
  77 create a new user with an expired password, and thus force the user to
  78 change the password on the first login attempt.</p>
  79
  80 <p>I'm not quite sure how to do that with the LDAP setup in Debian
  81 Edu, but did some initial testing with a local account.  The account
  82 and password aging information is available in /etc/shadow, but
  83 unfortunately, it is not possible to specify an expiration time for
  84 passwords, only a maximum age for passwords.</p>
  85
  86 <p>A freshly created account (using adduser test) will have these
  87 settings in /etc/shadow:</p>
  88
  89 <blockquote><pre>
  90 root@tjener:~# chage -l test
  91 Last password change                                    : May 02, 2010
  92 Password expires                                        : never
  93 Password inactive                                       : never
  94 Account expires                                         : never
  95 Minimum number of days between password change          : 0
  96 Maximum number of days between password change          : 99999
  97 Number of days of warning before password expires       : 7
  98 root@tjener:~#
  99 </pre></blockquote>
 100
 101 <p>The only way I could come up with to create a user with an expired
 102 account, is to change the date of the last password change to the
 103 lowest value possible (January 1th 1970), and the maximum password age
 104 to the difference in days between that date and today.  To make it
 105 simple, I went for 30 years (30 * 365 = 10950) and January 2th (to
 106 avoid testing if 0 is a valid value).</p>
 107
 108 <p>After using these commands to set it up, it seem to work as
 109 intended:</p>
 110
 111 <blockquote><pre>
 112 root@tjener:~# chage -d 1 test; chage -M 10950 test
 113 root@tjener:~# chage -l test
 114 Last password change                                    : Jan 02, 1970
 115 Password expires                                        : never
 116 Password inactive                                       : never
 117 Account expires                                         : never
 118 Minimum number of days between password change          : 0
 119 Maximum number of days between password change          : 10950
 120 Number of days of warning before password expires       : 7
 121 root@tjener:~#
 122 </pre></blockquote>
 123
 124 <p>So far I have tested this with ssh and console, and kdm (in
 125 Squeeze) login, and all ask for a new password before login in the
 126 user (with ssh, I was thrown out and had to log in again).</p>
 127
 128 <p>Perhaps we should set up something similar for Debian Edu, to make
 129 sure only the user itself have the account password?</p>
 130
 131 <p>If you want to comment on or help out with implementing this for
 132 Debian Edu, please contact us on debian-edu@lists.debian.org.</p>
 133
 134 <p>Update 2010-05-02 17:20: Paul Tötterman tells me on IRC that the
 135 shadow(8) page in Debian/testing now state that setting the date of
 136 last password change to zero (0) will force the password to be changed
 137 on the first login.  This was not mentioned in the manual in Lenny, so
 138 I did not notice this in my initial testing.  I have tested it on
 139 Squeeze, and '<tt>chage -d 0 username</tt>' do work there.  I have not
 140 tested it on Lenny yet.</p>
 141
 142 <p>Update 2010-05-02-19:05: Jim Paris tells me via email that an
 143 equivalent command to expire a password is '<tt>passwd -e
 144 username</tt>', which insert zero into the date of the last password
 145 change.</p>

 159   <div class="date">2010-04-28 20:40</div>
 160   <div class="body">
 161 <p>For some years now, I have wondered how we should handle laptops in
 162 Debian Edu.  The Debian Edu infrastructure is mostly designed to
 163 handle stationary computers, and less suited for computers that come
 164 and go.</p>
 165
 166 <p>Now I finally believe I have an sensible idea on how to adjust
 167 Debian Edu for laptops, by introducing a new profile for them, for
 168 example called Roaming Workstations.  Here are my thought on this.
 169 The setup would consist of the following:</p>
 170
 171 <ul>
 172
 173  <li>During installation, the user name of the owner / primary user of
 174    the laptop is requested and a local home directory is set up for
 175    the user, with uid and gid information fetched from the LDAP
 176    server.  This allow the user to work also when offline.  The
 177    central home directory can be available in a subdirectory on
 178    request, for example mounted via CIFS.  It could be mounted
 179    automatically when a user log in while on the Debian Edu network,
 180    and unmounted when the machine is taken away (network down,
 181    hibernate, etc), it can be set up to do automatic mounting on
 182    request (using autofs), or perhaps some GUI button on the desktop
 183    can be used to access it when needed.  Perhaps it is enough to use
 184    the fish protocol in KDE?</li>
 185
 186  <li>Password checking is set up to use LDAP or Kerberos
 187    authentication when the machine is on the Debian Edu network, and
 188    to cache the password for offline checking when the machine unable
 189    to reach the LDAP or Kerberos server.  This can be done using
 190    <a href="http://www.padl.com/OSS/pam_ccreds.html">libpam-ccreds</a>
 191    or the Fedora developed
 192    <a href="https://fedoraproject.org/wiki/Features/SSSD">System
 193    Security Services Daemon</a> packages.</li>
 194
 195  <li>File synchronisation with the central home directory is set up
 196    using a shared directory in both the local and the central home
 197    directory, using unison.</li>
 198
 199  <li>Printing should be set up to print to all printers broadcasting
 200    their existence on the local network, and should then work out of
 201    the box with CUPS.  For sites needing accurate printer quotas, some
 202    system with Kerberos authentication or printing via ssh could be
 203    implemented.</li>
 204
 205  <li>For users that should have local root access to their laptop,
 206    sudo should be used to allow this to the local user.</li>
 207
 208  <li>It would be nice if user and group information from LDAP is
 209    cached on the client, but given that there are entries for the
 210    local user and primary group in /etc/, it should not be needed.</li>
 211
 212 </ul>
 213
 214 <p>I believe all the pieces to implement this are in Debian/testing at
 215 the moment.  If we work quickly, we should be able to get this ready
 216 in time for the Squeeze release to freeze.  Some of the pieces need
 217 tweaking, like libpam-ccreds should get support for pam-auth-update
 218 (<a href="http://bugs.debian.org/566718">#566718</a>) and nslcd (or
 219 perhaps debian-edu-config) should get some integration code to stop
 220 its daemon when the LDAP server is unavailable to avoid long timeouts
 221 when disconnected from the net.  If we get Kerberos enabled, we need
 222 to make sure we avoid long timeouts there too.</p>

 225 please contact us on debian-edu@lists.debian.org.</p>

 243 touching copyright, virtual worlds, the future of man when the

 245 book titled "Content: Selected Essays on Technology, Creativity,
 246 Copyright, and the Future of the Future" is available with few

 268 <p><a href="http://www.nuug.no/aktiviteter/20100413-kerberos/">Yesterdays
 269 NUUG presentation</a> about Kerberos was inspiring, and reminded me
 270 about the need to start using Kerberos in Skolelinux.  Setting up a
 271 Kerberos server seem to be straight forward, and if we get this in
 272 place a long time before the Squeeze version of Debian freezes, we
 273 have a chance to migrate Skolelinux away from NFSv3 for the home
 274 directories, and over to an architecture where the infrastructure do
 275 not have to trust IP addresses and machines, and instead can trust
 276 users and cryptographic keys instead.</p>
 277
 278 <p>A challenge will be integration and administration.  Is there a
 279 Kerberos implementation for Debian where one can control the
 280 administration access in Kerberos using LDAP groups?  With it, the
 281 school administration will have to maintain access control using flat
 282 files on the main server, which give a huge potential for errors.</p>
 283
 284 <p>A related question I would like to know is how well Kerberos and
 285 pam-ccreds (offline password check) work together.  Anyone know?</p>
 286
 287 <p>Next step will be to use Kerberos for access control in Lwat and
 288 Nagios.  I have no idea how much work that will be to implement.  We
 289 would also need to document how to integrate with Windows AD, as such
 290 shared network will require two Kerberos realms that need to cooperate
 291 to work properly.</p>
 292
 293 <p>I believe a good start would be to start using Kerberos on the
 294 skolelinux.no machines, and this way get ourselves experience with
 295 configuration and integration.  A natural starting point would be
 296 setting up ldap.skolelinux.no as the Kerberos server, and migrate the
 297 rest of the machines from PAM via LDAP to PAM via Kerberos one at the
 298 time.</p>
 299
 300 <p>If you would like to contribute to get this working in Skolelinux,
 301 I recommend you to see the video recording from yesterdays NUUG
 302 presentation, and start using Kerberos at home.  The video show show
 303 up in a few days.</p>

 344 <p>6 years ago, as part of the Debian Edu development I am involved
 345 in, I asked for a hook in the kdm and gdm setup to run scripts as root
 346 when the user log out.  A bug was submitted against the xfree86-common
 347 package in 2004 (<a href="http://bugs.debian.org/230422">#230422</a>),
 348 and revisited every time Debian Edu was working on a new release.
 349 Today, this finally paid off.</p>
 350
 351 <p>The framework for this feature was today commited to the git
 352 repositry for the xorg package, and the git repository for xdm has
 353 been updated to use this framework.  Next on my agenda is to make sure
 354 kdm and gdm also add code to use this framework.</p>
 355
 356 <p>In Debian Edu, we want to ability to run commands as root when the
 357 user log out, to get rid of runaway processes and do general cleanup
 358 after a user.  With this framework in place, we finally can do that in
 359 a generic way that work with all display managers using this
 360 framework.  My goal is to get all display managers in Debian use it,
 361 similar to how they use the Xsession.d framework today.<p>

 398 <p>Jeg foretrekker å kjøpe bøker, og velger dermed å la være å bruke
 399 DRM-belastede digitale bøker.  Vet ikke helt hva jeg ville være villig
 400 til å betale for å leie en bok, men tror ikke det er mange kronene.
 401 Heldigvis er det mye bøker tilgjengelig uten slike restriksjoner, og
 402 de som vil ha tak i engelske bøker kan laste ned bøker som er
 403 tilgjengelig uten bruksbegresninger fra <a href="http://www.archive.org/">The
 404 Internet Archive</a>. Der er det pr. i dag 1 889 313 bøker
 405 tilgjengelig. De er tilgjengelig i flere formater. Besøk
 406 <a href="http://www.archive.org/details/texts">oversikten over tekster
 407 der</a> for å se hva de har.

 423 <p>On Tuesday, the Debian/Lenny based version of
 424 <a href="http://www.skolelinux.org/">Skolelinux</a> was finally
 425 shipped.  This was a major leap forward for the project, and I am very
 426 pleased that we finally got the release wrapped up.  Work on the first
 427 point release starts imediately, as we plan to get that one out a
 428 month after the major release, to include all fixes for bugs we found
 429 and fixed too late in the release process to include last Tuesday.</p>
 430
 431 <p>Perhaps it even is time for some partying?</p>
 432
 433 <p>After this first point release, my plan is to focus again on the
 434 next major release, based on Squeeze.  We will try to get as many of
 435 the fixes we need into the official Debian packages before the freeze,
 436 and have just a few weeks or months to make it happen.</p>

 452 <p>Ble nettopp gjort oppmerksom på en

 454 fra Danmark, der det hevdes at Folketinget har vedtatt at ODF skal
 455 brukes som dokumentutvekslingsformat i Staten.</p>
 456
 457 <p>Hyggelig lesning, spesielt hvis det viser seg at de av vedtatt
 458 kravlisten for hva som skal aksepteres som referert i kommentarfeltet
 459 til artikkelen og
 460 <a href="http://www.version2.dk/artikel/13693-er-ooxml-doemt-ude-her-er-kravene-til-en-offentlig-dokumentstandard">en
 461 annen artikkel</a> i samme nett-avis.  Liker spesielt godt denne:</p>
 462
 463 <p><blockquote> Det skal demonstreres, at standarden i sin helhed kan

 466
 467 <p>Noe slikt burde være et krav også i Norge.</p>
