I just switched from RHEL3 to RHEL4 on one of my servers. The
configuration files were just moved from one system to the other.
Macs and other unix computers used to be able to connect through port
631 to cups to do their printing on the RHEL3 system. They no longer
can.
I have selinux disable because I don't understand it completely and
did not want it interfering with printing.
I have 631 tcp and udp enabled in iptables.
The Macs time out saying that port 631 is busy on the server.
What do I need to open up?
