I'm a real newbie at this so disregard as necessary. I just set this up on my small home lan (4 machines). The server is running Debian potato and the clients Debian woody. I had to add this to my /etc/dhclient.conf on the client machines for it to update: send host-name "a_hostname"; send dhcp-client-identifier 01:03:d0:05:b7:55:8d; The identifier is the mac address plus a 01 prepended. Once I did this the updates took. The man pages for dhclient suggest that the default values it asks for should be sufficient (for dhcp) but (for dyn-dns updating) I had to do these options explicitly. hth, Jesse
