[ILUG] Who stole my localhost ?

[Gareth Eason]

	For what I'm guessing is this very reason - I have localhost A 
127.0.0.1 as a record in my caching DNS server. I don't recall setting 
it up so I'm guessing it's a default setting provided by RedHat. Perhaps 
that's what's missing - and the machine in question is configured to use 
DNS only? And not /etc/hosts?

	This is merely a speculative wild guess - I could be a million miles 
off :-)

	YMMV, usual disclaimers apply, etc.

	Best regards,
	-->Gar
