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
Interesting. I’ve changed my hostname on a few machines throughout the past and never ran into this. Good to know if I ever run into this in the future.
