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

 100 <p>Ble nettopp gjort oppmerksom på en
 101 <a href="http://www.version2.dk/artikel/13690-breaking-odf-vinder-dokumentformat-krigen ">nyhet fra Version2</a>
 102 fra Danmark, der det hevdes at Folketinget har vedtatt at ODF skal
 103 brukes som dokumentutvekslingsformat i Staten.</p>
 104
 105 <p>Hyggelig lesning, spesielt hvis det viser seg at de av vedtatt
 106 kravlisten for hva som skal aksepteres som referert i kommentarfeltet
 107 til artikkelen og
 108 <a href="http://www.version2.dk/artikel/13693-er-ooxml-doemt-ude-her-er-kravene-til-en-offentlig-dokumentstandard">en
 109 annen artikkel</a> i samme nett-avis.  Liker spesielt godt denne:</p>
 110
 111 <p><blockquote> Det skal demonstreres, at standarden i sin helhed kan
 112 implementeres af alle direkte i sin helhed på flere
 113 platforme.</blockquote></p>
 114
 115 <p>Noe slikt burde være et krav også i Norge.</p>
