  14                 <description>&lt;p&gt;One of the new features in the next Debian/Lenny based release of
  15 Debian Edu/Skolelinux, which is scheduled for release in the next few
  16 days, is automatic configuration of the service monitoring system
  17 Nagios.  The previous release had automatic configuration of trend
  18 analysis using Munin, and this Lenny based release take that a step
  19 further.&lt;/p&gt;
  20
  21 &lt;p&gt;When installing a Debian Edu Main-server, it is automatically
  22 configured as a Munin and Nagios server.  In addition, it is
  23 configured to be a server for the
  24 &lt;a href=&quot;http://wiki.debian.org/DebianEdu/HowTo/SiteSummary&quot;&gt;SiteSummary
  25 system&lt;/a&gt; I have written for use in Debian Edu.  The SiteSummary
  26 system is inspired by a system used by the University of Oslo where I
  27 work.  In short, the system provide a centralised collector of
  28 information about the computers on the network, and a client on each
  29 computer submitting information to this collector.  This allow for
  30 automatic information on which packages are installed on each machine,
  31 which kernel the machines are using, what kind of configuration the
  32 packages got etc.  This also allow us to automatically generate Munin
  33 and Nagios configuration.&lt;/p&gt;
  34
  35 &lt;p&gt;All computers reporting to the sitesummary collector with the
  36 munin-node package installed is automatically enabled as a Munin
  37 client and graphs from the statistics collected from that machine show
  38 up automatically on http://www/munin/ on the Main-server.&lt;/p&gt;
  39
  40 &lt;p&gt;All non-laptop computers reporting to the sitesummary collector are
  41 automatically monitored for network presence (ping and any network
  42 services detected).  In addition, all computers (also laptops) with
  43 the nagios-nrpe-server package installed and configured the way
  44 sitesummary would configure it, are monitored for full disks, software
  45 raid status, swap free and other checks that need to run locally on
  46 the machine.&lt;/p&gt;
  47
  48 &lt;p&gt;The result is that the administrator on a school using Debian Edu
  49 based on Lenny will be able to check the health of his installation
  50 with one look at the Nagios settings, without having to spend any time
  51 keeping the Nagios configuration up-to-date.&lt;/p&gt;
  52
  53 &lt;p&gt;The only configuration one need to do to get Nagios up and running
  54 is to set the password used to get access via HTTP.  The system
  55 administrator need to run &quot;&lt;tt&gt;htpasswd /etc/nagios3/htpasswd.users
  56 nagiosadmin&lt;/tt&gt;&quot; to create a nagiosadmin user and set a password for
  57 it to be able to log into the Nagios web pages.  After that,
  58 everything is taken care of.&lt;/p&gt;

  64                 <link>http://people.skolelinux.org/pere/blog/Danmark_g_r_for_ODF_.html</link>

  67                 <description>&lt;p&gt;Ble nettopp gjort oppmerksom på en
  68 &lt;a href=&quot;http://www.version2.dk/artikel/13690-breaking-odf-vinder-dokumentformat-krigen &quot;&gt;nyhet fra Version2&lt;/a&gt;
  69 fra Danmark, der det hevdes at Folketinget har vedtatt at ODF skal
  70 brukes som dokumentutvekslingsformat i Staten.&lt;/p&gt;
  71
  72 &lt;p&gt;Hyggelig lesning, spesielt hvis det viser seg at de av vedtatt
  73 kravlisten for hva som skal aksepteres som referert i kommentarfeltet
  74 til artikkelen og
  75 &lt;a href=&quot;http://www.version2.dk/artikel/13693-er-ooxml-doemt-ude-her-er-kravene-til-en-offentlig-dokumentstandard&quot;&gt;en
  76 annen artikkel&lt;/a&gt; i samme nett-avis.  Liker spesielt godt denne:&lt;/p&gt;
  77
  78 &lt;p&gt;&lt;blockquote&gt; Det skal demonstreres, at standarden i sin helhed kan
  79 implementeres af alle direkte i sin helhed på flere
  80 platforme.&lt;/blockquote&gt;&lt;/p&gt;
  81
  82 &lt;p&gt;Noe slikt burde være et krav også i Norge.&lt;/p&gt;
