[Helge Blischke]

On your production server, access to CUPS is restricted to the local
host, and the

created by
some RH configuration tool. You should use *that* to grant access from
the boxes you 
need.

CUPS is running on both boxes (ran chkconfig --list cups) my config files are exactly the same, except for the server name. There are no obvious errors in the error log. The differences that are obvious to me are the lines at the bottom of the cupsd.conf that ask you not to edit whats beneath as its been generated by cups. service cups status reports that both are running,
