Also, also.. keep in mind that 'fail2ban' does some processing on the log
messages to which it MAY take action.
It's taking, essentially, untrusted external input and ... acting as 'root'.

that sounds like a recipe for a disaster, to me... is the code utf-8 safe?
are the actions it takes safe in the context of whatever PTR record content
may come down the pipe? or apache(equivalent) log message parsing?
