      Before using Fail2Ban for the first time you should edit jail
      configuration and enable the jails that you want to use, for instance
      ssh-ipfw. Also make sure that they point to the correct configuration
      path. I.e. on Mountain Lion the sshd logfile should point to
      /var/log/system.log.

      The Fail2Ban wiki has two pages with instructions for MacOS X Server that
      describes how to set up the Jails for the standard MacOS X Server
      services for the respective releases.
