SSH hank attempts… bad?

More pain for the user, but another layer of security can be added by using 
port knocking. 

With port knocking you could probably get away without any of the fancy ip 
blocking rules and log watchers, since your port is not even open until you 
give the magic knock, and then only to the originating ip address.
