Fail2Ban Error – Iptables returned 200

This relates to seeing things like this in /var/log/fail2ban.log when restarting the fail2ban service:

2011-12-21 23:06:03,471 fail2ban.actions.action: ERROR  iptables -D INPUT -p tcp -m multiport --dports http,https -j fail2ban-apache-wordpress-login
iptables -F fail2ban-apache-wordpress-login
iptables -X fail2ban-apache-wordpress-login returned 200

The very simple cause is that iptables only allows rules of up to 30 characters. In the above case, changing the name of the filter to ‘apache-wp-login’ did the trick.
