While I did change the config entry and it is logging IP addresses, apparently that's not my problem.  Even when using legit IP addresses my iptables rejects aren't working?  I guess that means its not a forward/reverse DNS problem causing my issue.  I have to use /etc/hosts.deny to stop some of the ssh attacks.  Very weird.

If you want some help to diagnose your iptables config, please give some details on what the config is (output of "iptables -nvL" is a good start) and which specific case makes you think it is not working.

If you want good tips on how to secure SSH, please do also check this wiki page: http://wiki.centos.org/HowTos/Network/SecuringSSH
