I still can't seem to understand how to add other interfaces to fail2ban. Right now all I would like to add is samba and ISPConfig. I can't seem to get the procedure right, since when I try to add them nothing happens. What is failregex, do I need this to add something? I'm a bit new and this stuff right here doesn't make any sense to me. Also I noticed that fail2ban uses polling, now I see no effect on CPU usage, but what is gamin? Has anyone here used it? Just curious which one handles better. I would take interrupts over polling anytime.
