sshd no longer accepting logins

[Mark Knecht]

Hi,
   After doing up2date today our new machine is no longer accepting
logins via ssh. Probably this is either a config issue or a firewall
issue. The sshd daemon is running:

[root at dragonfly etc]# ps aux | grep sshd
root      4641  0.0  0.3  5444 1576 ?        Ss   14:51   0:00 /usr/sbin/sshd
root      6217  0.0  0.1  4708  692 pts/1    S+   14:58   0:00 grep sshd
[root at dragonfly etc]#

   I'm looking at sshd_config file, but assuming it's not the culprit
how do I configure the firewall provide on FC3 to allow ssh logins?
This was an option during the install that I had to choose. I think
possibly the update unchose it for me?

Thanks,
Mark
