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
You guys are having own hostname in hosts file?
Never, there’s no need for it. I can reach it with localhost or 127.0.0.1, so why would I even put it in?
seems like a pretty common practice across Linux distributions
/etc/hostname for the actual hostname, and a mapping in /etc/hosts pointing it at a 127.x.x.x address
