Hi Fred,

That is great. When I started on Linux that was one  of the very first
things I did. Every machine, including servers, has port 22 replaced by
a unique alternative port. Port 22 is also blocked in IPtables.

There is an army of dangerous nutters attempting to break-in to
everything. They often mask their attacks using compromised Windoze
computers all around the world.
