Offtopic but why are people using high port numbers? Additional security due to a nonstandard port? If so, does that go together with anything additional like port knocking? Or is it multiple hosts on the same IP, but different ports?
It's to keep my logs cleaner. It doesn't add any security value since the port is still open. I don't allow password auth. I was just always annoyed with how many times port 22 was getting hit everyday by attackers.
