It was all going great with my #Fail2Ban #SSH jails on two of my VPSs until I changed the port SSH listens on. F2B seems to only work when SSH port is 22. Anyone experienced this? I wasted enough hours debugging this that I've now removed F2B out of frustration.

@syntax I think you have to add a port config file somewhere for Fail2Ban I'd you want it on another port. Two questions, though. 1: why do you want to change your ssh port? 2: why use fail2ban? It is unnecessary unless you're authenticating through exclusively a password.

I started using it mostly for additional layer of security although I already have UFW active. I allow password auth for a non-root user just in case I don't have access to my keys.
