SSH

[Jacques B.]

The thoughts that come to mind with me is your iptables.  Do you have
a rule entered to allow incoming port 22 connections?  Even more basic
than that are you certain the sshd is running?  You can test that as
suggested by Paul.  If you are coming through a router, is the
router's firewall settings configured to allow incoming port 22?  If
so, is it then configured to forward it to your FC PC?
