I've attempted to set up fail2ban to ban attackers that trigger modsecurity rules.  But fail2ban is....failing to ban them.  I get plenty of bans based on apache-auth and fakegooglebot rules, but never on modsecurity.

My original filter in apache-modsecurity.conf looked like this (I believe this was the default)

failregex = ^%(_apache_error_client)s ModSecurity:  (\[.*?\] )*Access denied with code [45]\d\d.*$

After noticing that nothing got banned, based on a post in Server Fault I changed it to

failregex = ^%(_apache_error_client)s .*ModSecurity:  (\[.*?\] )*Access denied with code [45]\d\d.*$

But still nothing.

Has anyone tried this, and gotten it to work? (I am pretty ignorant of regex's and have just been looking for a canned solution).

Thanks in advance.

Bill
