FACT(s) (Environment):
UNIX
CAUSE:
The networking on the UNIX box is not configured properly.
CAUSE:
Bad network resolution of the hostname due to server machine having a fixed IP address and not using DNS.
FIX:
/etc/hosts file should look like this:
127.0.0.1 localhost
192.168.123.3 aurvandil.kevbarbs.servebeer.com aurvandil
<other possible entries>
/etc/sysconfig
etwork should contain entry
HOSTNAME=aurvandil
OS command "hostname" should return "aurvandil"
FIX:
Ensure to use DNS.
If using DNS isn't possible, a possible workaround is to specify in the hosts file the hostname in place of "localhost".
