[K12OSN] 2 Questions: X11VNC & Iptables

[Petre Scheie]

Try running redhat-config-securitylevel-tui.  This is the terminal-based 
version of the tool for configuring the firewall.  It's ugly but it does 
allow you to specify specific port numbers in addition to the standard 
services, and it doesn't depend on any X libraries.  RH apparently 
removed the 'Other ports' option in FC1 for reasons I can't fathom 
(bangs head against the wall).

After you've run the above tool, you should have a iptables files in 
/etc/sysconfig which you can look at to see what's going on.
