troed, 
Some poor person's SSH-bot is trying to log into one of my systems.
As root.
fail2ban jails their IPs (a bunch) over and over, and yet they've been at it for two days now.
Somehow I would like to communicate back to them that;
root cannot login remotely. I mean. Come on.
this system only accepts keybased authentication
I'm sure there are other less secure targets they could go spend their resources on. Please, let me help!
