In the recent Debian Edu versions, the +sitesummary +system 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.
+ +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:
+ ++ ++perl -MSiteSummary -e 'for_all_hosts(sub { print join(" ", get_macaddresses(shift)), "\n"; });' +
This will list all MAC addresses assosiated with all machine, one +line per machine and with space between the MAC addresses.
+ +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.
