Now I think I know what is going on. Please correct any mistakes. At some point, my dhclient told Cable One's dhcp server that I wanted the hostname "stmike". The name "stmike" is being stored by the server and sent to me whenever dhclient does its thing, e.g. at boot time. Here is what I think is supposed to be happening at reboot. dhclient acquires an IP address, but not a hostname. Someone does a DNS lookup on the IP address and uses the result for the hostname. Again, please correct any mistakes. What I think caused the difference: An accidentally deleted dhclient.conf file. According to its man page, host-name is among the default requests. My troubles began after rebooting to get rid of a hung process that I could not kill. The reboot sequence required that I run fsck. My suspicion is that dhclient.conf got deleted in the mess. Would someone tell me whether an FC3 installation running dhclient normally has a non-empty dhclient.conf? The cure would be to provide a useful dhclient.conf, remove dhclient-eth0.leases, and reboot. The result should be a new lease that does not include a hostname. Is there a way to tell the server to forget the name "stmike"? If for some reason dhclient asks for a hostname again, I'd like that name to be gone. -- Mike hennebry@xxxxxxxxxxxxxxxxxxxxx "I AM DEATH, NOT TAXES. *I* ONLY TURN UP ONCE." -- Death
