[CentOS] Fail2Ban

Hi all,

I am trying to get fail2ban going on my server and its log message
reports the following error

2009-02-16 17:42:05,339 ERROR: 'iptables -L INPUT | grep -q
fail2ban-SSH' returned 256
2009-02-16 17:42:05,354 ERROR: 'iptables -D INPUT -p tcp --dport ssh
-j fail2ban-SSH

Is this because of the way the RedHat tool sets up the firewall?

Thanks for any responses.
