Since taking care of these things I've had no more trouble and since installing DenyHosts I haven't had to spend anywhere the amount of time making adjustments to my firewall either.
Thanks. I just cant figure out why denyhosts isnt working. I had also disabled remote root login, but denyhost isnt catching it.
Sorry for asking the obvious - what is the output from: - /sbin/service denyhosts status - /sbin/chkconfig --list denyhosts
You could also try to reset the configuration by copying /usr/share/doc/denyhosts-2.6/denyhosts.cfg-dist to /etc/denyhosts/denyhosts.cfg (don't forget to backup your configuration).
