+&lt;p&gt;In the recent Debian Edu versions, the
+&lt;a href=&quot;http://wiki.debian.org/DebianEdu/HowTo/SiteSummary&quot;&gt;sitesummary
+system&lt;/a&gt; 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.&lt;/p&gt;
+
+&lt;p&gt;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:&lt;/p&gt;
+
+&lt;blockquote&gt;&lt;pre&gt;
+perl -MSiteSummary -e &#39;for_all_hosts(sub { print join(&quot; &quot;, get_macaddresses(shift)), &quot;\n&quot;; });&#39;
+&lt;/pre&gt;&lt;/blockquote&gt;
+
+&lt;p&gt;This will list all MAC addresses assosiated with all machine, one
+line per machine and with space between the MAC addresses.&lt;/p&gt;
+
+&lt;p&gt;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.&lt;/p&gt;

-&lt;p&gt;On Tuesday, the Debian/Lenny based version of
-&lt;a href=&quot;http://www.skolelinux.org/&quot;&gt;Skolelinux&lt;/a&gt; was finally
-shipped.  This was a major leap forward for the project, and I am very
-pleased that we finally got the release wrapped up.  Work on the first
-point release starts imediately, as we plan to get that one out a
-month after the major release, to include all fixes for bugs we found
-and fixed too late in the release process to include last Tuesday.&lt;/p&gt;
-
-&lt;p&gt;Perhaps it even is time for some partying?&lt;/p&gt;
-
-&lt;p&gt;After this first point release, my plan is to focus again on the
-next major release, based on Squeeze.  We will try to get as many of
-the fixes we need into the official Debian packages before the freeze,
-and have just a few weeks or months to make it happen.&lt;/p&gt;
