Before using Fail2Ban for the first time you should edit the 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 Server that
|
|
describes how to set up the Jails for the standard macOS Server
|
|
services for the respective releases.
