+ Sitesummary tip: Listing MAC address of all clients

+<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>
+
+<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>
+
+<blockquote><pre>
+perl -MSiteSummary -e 'for_all_hosts(sub { print join(" ", get_macaddresses(shift)), "\n"; });'
+</pre></blockquote>
+
+<p>This will list all MAC addresses assosiated with all machine, one
+line per machine and with space between the MAC addresses.</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>On Tuesday, the Debian/Lenny based version of
-<a href="http://www.skolelinux.org/">Skolelinux</a> 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.</p>
-
-<p>Perhaps it even is time for some partying?</p>
-
-<p>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.</p>
