  31       <div class="body">
  32         <p>One of the new features in the next Debian/Lenny based release of
  33 Debian Edu/Skolelinux, which is scheduled for release in the next few
  34 days, is automatic configuration of the service monitoring system
  35 Nagios.  The previous release had automatic configuration of trend
  36 analysis using Munin, and this Lenny based release take that a step
  37 further.</p>
  38
  39 <p>When installing a Debian Edu Main-server, it is automatically
  40 configured as a Munin and Nagios server.  In addition, it is
  41 configured to be a server for the
  42 <a href="http://wiki.debian.org/DebianEdu/HowTo/SiteSummary">SiteSummary
  43 system</a> I have written for use in Debian Edu.  The SiteSummary
  44 system is inspired by a system used by the University of Oslo where I
  45 work.  In short, the system provide a centralised collector of
  46 information about the computers on the network, and a client on each
  47 computer submitting information to this collector.  This allow for
  48 automatic information on which packages are installed on each machine,
  49 which kernel the machines are using, what kind of configuration the
  50 packages got etc.  This also allow us to automatically generate Munin
  51 and Nagios configuration.</p>
  52
  53 <p>All computers reporting to the sitesummary collector with the
  54 munin-node package installed is automatically enabled as a Munin
  55 client and graphs from the statistics collected from that machine show
  56 up automatically on http://www/munin/ on the Main-server.</p>
  57
  58 <p>All non-laptop computers reporting to the sitesummary collector are
  59 automatically monitored for network presence (ping and any network
  60 services detected).  In addition, all computers (also laptops) with
  61 the nagios-nrpe-server package installed and configured the way
  62 sitesummary would configure it, are monitored for full disks, software
  63 raid status, swap free and other checks that need to run locally on
  64 the machine.</p>
  65
  66 <p>The result is that the administrator on a school using Debian Edu
  67 based on Lenny will be able to check the health of his installation
  68 with one look at the Nagios settings, without having to spend any time
  69 keeping the Nagios configuration up-to-date.</p>
  70
  71 <p>The only configuration one need to do to get Nagios up and running
  72 is to set the password used to get access via HTTP.  The system
  73 administrator need to run "<tt>htpasswd /etc/nagios3/htpasswd.users
  74 nagiosadmin</tt>" to create a nagiosadmin user and set a password for
  75 it to be able to log into the Nagios web pages.  After that,
  76 everything is taken care of.</p>

  97         <p>Ble nettopp gjort oppmerksom på en
  98 <a href="http://www.version2.dk/artikel/13690-breaking-odf-vinder-dokumentformat-krigen ">nyhet fra Version2</a>
  99 fra Danmark, der det hevdes at Folketinget har vedtatt at ODF skal
 100 brukes som dokumentutvekslingsformat i Staten.</p>
 101
 102 <p>Hyggelig lesning, spesielt hvis det viser seg at de av vedtatt
 103 kravlisten for hva som skal aksepteres som referert i kommentarfeltet
 104 til artikkelen og
 105 <a href="http://www.version2.dk/artikel/13693-er-ooxml-doemt-ude-her-er-kravene-til-en-offentlig-dokumentstandard">en
 106 annen artikkel</a> i samme nett-avis.  Liker spesielt godt denne:</p>
 107
 108 <p><blockquote> Det skal demonstreres, at standarden i sin helhed kan
 109 implementeres af alle direkte i sin helhed på flere
 110 platforme.</blockquote></p>
 111
 112 <p>Noe slikt burde være et krav også i Norge.</p>
