hehe, so … if you ever change the hostname of a Linux machine, you really really ought to double-check /etc/hosts to make the same hostname change there
it’s surprising just how much will break if a machine’s own hostname isn’t resolvable to a 127.x.x.x address :P
This reminds me… My server demands to be known as hostname.local on my network. The other machines just respond to just hostname. I really should figure out why that is.
