[K12OSN] 2 Questions: X11VNC & Iptables

[Petre Scheie]

I should add that one shortcoming of redhat-config-securitylevel-tui is 
that it does not read the existing /etc/sysconfig/iptables 
configuration.  That means every time you run it, you're starting over; 
it would probably be a good idea to have a separate window open with 
iptables loaded in it so you can be sure to get all the previous settings.
