I'm running centos 6.7 64 bit and fail2ban-0.8.14-1.shmz65.1.128.noarch
which I got from 'yum install fail2ban'. The problem is I'm getting a lot
of strange entries in my logwatch file every day concerning fail2ban.
Here's an example of what I get every day in the logwatch: The first bit
about banned services is normal, it's the **Unmatched Entries** section I
don't understand.
