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

  69 &lt;p&gt;Ble nettopp gjort oppmerksom på en
  70 &lt;a href=&quot;http://www.version2.dk/artikel/13690-breaking-odf-vinder-dokumentformat-krigen &quot;&gt;nyhet fra Version2&lt;/a&gt;
  71 fra Danmark, der det hevdes at Folketinget har vedtatt at ODF skal
  72 brukes som dokumentutvekslingsformat i Staten.&lt;/p&gt;
  73
  74 &lt;p&gt;Hyggelig lesning, spesielt hvis det viser seg at de av vedtatt
  75 kravlisten for hva som skal aksepteres som referert i kommentarfeltet
  76 til artikkelen og
  77 &lt;a href=&quot;http://www.version2.dk/artikel/13693-er-ooxml-doemt-ude-her-er-kravene-til-en-offentlig-dokumentstandard&quot;&gt;en
  78 annen artikkel&lt;/a&gt; i samme nett-avis.  Liker spesielt godt denne:&lt;/p&gt;
  79
  80 &lt;p&gt;&lt;blockquote&gt; Det skal demonstreres, at standarden i sin helhed kan
  81 implementeres af alle direkte i sin helhed på flere
  82 platforme.&lt;/blockquote&gt;&lt;/p&gt;
  83
  84 &lt;p&gt;Noe slikt burde være et krav også i Norge.&lt;/p&gt;
