I've been trying to get remote printing between two RH7.2 systems to work with /iptables/. I've tried various combinations allowing ports 515 and 721:731, but it still doesn't work.
If I open up *all* destination ports (boo!) coming from the remote printing machine with IP address "a.b.c.d", it works: iptables -t filter -A INPUT -p tcp -s a.b.c.d --dport 0: -j ACCEPT Also, if I request remote printing via /lpr/ to "a.b.c.d" from a non-Linux machine (DU/Tru64) is works fine. So, I don't feel the problem is in the remote machine. It's got to be an incorrect /iptables/ configuration! Maybe the easiest way for me to configure things is through an explanation from someone regarding just which ports (both in and out) are used for printing under RH. Of course, actual /iptables/ commands will be fine (preferred? ;-)) as well!
