-Jeg synes ethvert møblert hjem bør ha sin egen replikator. Og for
-å få min replikator på plass, har jeg som del av
-
NUUGs
-3D-skriverprosjekt bestilt deler til en
-
reprap fra utlandet, som skal
-bygges sammen slik at den kan demonstreres på Go Open 2009 i april.
-Foreløbig plan er å bygge to i parallell, en basert på byggesett
-fra utlandet, og en basert på deler skrevet ut på 3D-skriveren til
-Institutt for Informatikk ved Universitetet i Oslo. Jeg har fokusert
-på byggesettet, og håper noen andre vil ta ansvar for den
-hjemmelagede utgaven. :)

Nå er det den lange ventetiden som rår, etter at begge
-byggesettene er bestilt og betalt. Dog har visst den første pakken
-gått tapt etter at postens fikk den utlevert i Norge. Den er ferdig
-fortollet, og pakkelapp kom i postkassen før pakken var klar til
-henting. Det var 2008-11-07. Postens sporingssystem forteller at
-pakken ikke har beveget seg siden 2008-11-05, da den var innom
-omlastingsterminalen i Oslo. Dette var elektronikkbyggesettet som kom
-fra USA. Mekanikkbyggesettet er ennå ikke sendt fra England, og jeg
-håper det ikke går tapt på samme vis.

One of the new features in the next Debian/Lenny based release of
+Debian Edu/Skolelinux, which is scheduled for release in the next few
+days, is automatic configuration of the service monitoring system
+Nagios. The previous release had automatic configuration of trend
+analysis using Munin, and this Lenny based release take that a step
+further.
+
+
When installing a Debian Edu Main-server, it is automatically
+configured as a Munin and Nagios server. In addition, it is
+configured to be a server for the
+SiteSummary
+system I have written for use in Debian Edu. The SiteSummary
+system is inspired by a system used by the University of Oslo where I
+work. In short, the system provide a centralised collector of
+information about the computers on the network, and a client on each
+computer submitting information to this collector. This allow for
+automatic information on which packages are installed on each machine,
+which kernel the machines are using, what kind of configuration the
+packages got etc. This also allow us to automatically generate Munin
+and Nagios configuration.
+
+
All computers reporting to the sitesummary collector with the
+munin-node package installed is automatically enabled as a Munin
+client and graphs from the statistics collected from that machine show
+up automatically on http://www/munin/ on the Main-server.
+
+
All non-laptop computers reporting to the sitesummary collector are
+automatically monitored for network presence (ping and any network
+services detected). In addition, all computers (also laptops) with
+the nagios-nrpe-server package installed and configured the way
+sitesummary would configure it, are monitored for full disks, software
+raid status, swap free and other checks that need to run locally on
+the machine.
+
+
The result is that the administrator on a school using Debian Edu
+based on Lenny will be able to check the health of his installation
+with one look at the Nagios settings, without having to spend any time
+keeping the Nagios configuration up-to-date.
+
+
The only configuration one need to do to get Nagios up and running
+is to set the password used to get access via HTTP. The system
+administrator need to run "htpasswd /etc/nagios3/htpasswd.users
+nagiosadmin" to create a nagiosadmin user and set a password for
+it to be able to log into the Nagios web pages. After that,
+everything is taken care of.
