localhost in /etc/hosts

[Hans du Plooy <koffiejunkielistlurker@koffiejunkie.za.net>]

Hi guys,

Just wondering, which is correct:

127.0.0.1        localhost.localdomain        localhost

or

127.0.0.1        localhost

The linux networking howto
(http://www.tldp.org/HOWTO/NET3-4-HOWTO-5.html) muddies the water even
more:

127.0.0.1      localhost     loopback

I was always under the impression the first is the proper way.  I seem
to be having issues with resovling localhost for some web applications
on my Sarge server (127.0.0.1 localhost) but when I fix the hosts file,
it works, but breaks other things (like mysql usernames).

Thanks
Hans
