This is a joke right?

If you have password authentication disabled then it shouldn't matter how many thousands of times a day people are scanning and probing sshd. Port knockers, fail2ban, and things of that nature are just security by obscurity that don't materially increase your security posture. If sshd is written correctly and securely it doesn't matter if people are trying to probe your system, if it's not written correctly and securely you're SOL no matter what.

But ssh is written correctly. Now that other thing isn't. :D

I fail to see a problem here.
