Edit /etc/hosts and make sure your host name >is not in the 127.0.0.1 line (put it into separate line with your >host's IP address). Or even just remove your hostname from the 127.0.0.1 line and DON'T put it in anywhere else. This business of the installer tossing the host name on the 127.0.0.1 line of /etc/hosts is silly, and results in a known step in every installation of a server that says "go edit /etc/hosts, remove host name". I'm sure it helps something, somewhere, but it makes a mess in server environments. >_______________________________________________ >CentOS mailing list >CentOS at centos.org >http://lists.centos.org/mailman/listinfo/centos
