After running lsof -i, the result is
COMMAND    PID    USER   FD   TYPE DEVICE SIZE NODE NAME
portmap    685     rpc    3u  IPv4   1966       UDP *:sunrpc

sendmail  1092    root    4u  IPv4   2417       TCP

and running lsof -i tcp |grep 22 gives me nothing. I did not install 
FC2T2, I upgraded from FC2T1 to FC2T2
