Description Lon Hohberger 2007-08-22 19:48:35 UTC 
Description of problem:

Sometimes, people do bad things in /etc/hosts, like:

127.0.0.1 my-test.redhat.com  my-test localhost.localdomain localhost


If you add 'my-test.redhat.com' to Luci, it will work fine, but there are some
side effects which will be hit later:

(a) If you fix /etc/hosts, the host must be deleted from Conga (Ryan noticed
this) and re-added in order to continue administration, despite the certificates
being available and "trusted".  (If part of a cluster, cluster.conf may need to
me manually updated as well.)

(b) If you don't fix /etc/hosts, CMAN will refuse to start, citing inability to
find broadcast (or multicast) matches.

The request is to minimally check /etc/hosts and make sure the hostname we're
talking to isn't listed on the same line as localhost and/or 127.x.x.x (or the
equivalent in ipv6 notation)
