- <p>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.</p>
-
-<p>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
-<a href="http://wiki.debian.org/DebianEdu/HowTo/SiteSummary">SiteSummary
-system</a> 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.</p>
-
-<p>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.</p>
-
-<p>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.</p>
+ <p>The next version of <a href="http://www.skolelinux.org/">Debian Edu
+/ Skolelinux</a> will include a new tool
+<tt>sitesummary2ldapdhcp</tt>, which can be used to quickly set up all
+the computers in a school without much manual labour. Here is a short
+summary on how to use it to set up a new school.</p>
-<p>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.</p>
+<p>First, install a combined Main Server and Thin Client Server as the
+central server in the network. Next, PXE boot all the client machines
+as thin clients and wait 5 minutes after the last client booted to
+allow the clients to report their existence to the central server. When
+this is done, log on to the central server and run
+<tt>sitesummary2ldapdhcp -a</tt> in the <tt>konsole</tt> to use the
+collected information to generate system objects in LDAP. The output
+will look similar to this:</p>
-<p>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 "<tt>htpasswd /etc/nagios3/htpasswd.users
-nagiosadmin</tt>" 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.</p>

- <p>In the recent Debian Edu versions, the
-<a href="http://wiki.debian.org/DebianEdu/HowTo/SiteSummary">sitesummary
-system</a> is used to keep track of the machines in the school
-network. Each machine will automatically report its status to the
-central server after boot and once per night. The network setup is
-also reported, and using this information it is possible to get the
-MAC address of all network interfaces in the machines. This is useful
-to update the DHCP configuration.</p>
+Enter password if you want to activate these changes, and ^c to abort.
-<p>To give some idea how to use sitesummary, here is a one-liner to
-ist all MAC addresses of all machines reporting to sitesummary. Run
-this on the collector host:</p>
+Connecting to LDAP as cn=admin,ou=ldap-access,dc=skole,dc=skolelinux,dc=no

-<blockquote><pre>

-</pre></blockquote>
+<p>After providing the LDAP administrative password (the same as the
+root password set during installation), the LDAP database will be
+populated with system objects for each PXE booted machine with
+automatically generated names. The final step to set up the school is
+then to log into <a href="https://oss.gonicus.de/labs/gosa/">GOsa</a>,
+the web based user, group and system administration system to change
+system names, add systems to the correct host groups and finally
+enable DHCP and DNS for the systems. All clients that should be used
+as diskless workstations should be added to the workstation-hosts
+group. After this is done, all computers can be booted again via PXE
+and get their assigned names and group based configuration
+automatically.</p>
-<p>This will list all MAC addresses assosiated with all machine, one
-line per machine and with space between the MAC addresses.</p>
+<p>We plan to release beta3 with the updated version of this feature
+enabled this weekend. You might want to give it a try.</p>
-<p>To allow system administrators easier job at adding static DHCP
-addresses for hosts, it would be possible to extend this to fetch
-machine information from sitesummary and update the DHCP and DNS
-tables in LDAP using this information. Such tool is unfortunately not
-written yet.</p>
+<p>Update 2012-01-28: When calling sitesummary2ldapdhcp to add new
+hosts, one need to add the option -a. I forgot to mention this in my
+original text, and have added it to the text now.</p>
