By default the dhcp3 client doesn't send hostnames unless it is configured to do so. I would start there. http://www.debian.org/doc/manuals/reference/ch05.en.html#_the_network_interface_served_by_the_dhcp Add the hostname directive as described in that reference. Hopefully that will be the magic sauce to have your dhcp server respond to you. During the dhcp time your /var/log/syslog will be logging a trail of information about the network connection. What it says there would be useful information. $ grep dhclient /var/log/syslog Bob
