Hi,
I'm working on several CentOS and one RHEL servers. I needed to open a port
the other day so I did a search and the info I found lead me to believe the
only way to open or close a port was via iptables. Is that the complete story?
For example, if I want to open port 3306 for MySql I nee
Yes however you can open the port from the GUI under
system-> administration -> security level and firewall
if you don't want to poke around on the command line.
Likely the reason you don't have to open the special service for ssh is that
sshd is a trusted service.

and scripts in /usr/share/system-config-securitylevel/ for the GUI to set
open ports.
The file that matters is /etc/sysconfig/iptables
it generally looks like this (I grabbed this from a centos5.5 box):

For example, if
/etc/services - is used to map ports and service-names to protocols, such as
- telnet 23/tcp
The name "telnet" is then referenced on /etc/inetd.conf which would then map
these "service-names" to corresponding server that would get spawned(binary
executable). If you are on a centos, check for xine
