I use debian stable (sarge) and the dhcp3-client package. I register my hostname by adding
send hostname "foo"; in /etc/dhcp3/dhclient.conf. Everything works fine but for some reason the DHCP/DNS server (which I don't control) loses the hostname registration and the next day I need to connect to my machine using the IP. Once I logon, I do ifup --force eth0 and the hostname is registered again. This is obviously not nice, so is it possible to: 1. configure dhclient to send the hostname at a certain interval? 2. configure dhclient to send just the hostname? 3. control the interval at which dhclient renews the lease and set it to a few hours so that the hostname is sent more frequently? Do you have any other suggestion for approaching this? Again, I cannot touch the server. In the worst case I would probably set a cron job to do "ifup --force eth0" :-(
