I don't see what the net effect is. You'll still see unauthorized connection
attempts by ankle-biters on port 22. If your implementation is vulnerable,
running a service on a non-standard port offers little-to-no protection.
The number of TCP ports is very small, and the number of potential source
computers for a lazy and quiet scan to determine what service you're
running SSHD on is large. Are you going to change the service port on
a daily basis? Hourly?
