chkconfig sshd off

port 22 is for ssh. Your ssh daemon is running

You should close this port in you firewall policy. I'm currently not in a fedora system, so excuse me if I don't have the exact location, but I beleive you can find it in System -> Administartion -> Security. Then disable ssh there.

and just a thought,

to stop the sshd server, which allows you to login to your box, from starting at boot, System -> Administration -> services...

the above one only sets the firewall
