Moving sshd from port 22 to port 137, 138 or 139. Nasty eh?

don't do that! Lots of (access) isps around the world (esp here in
Europe) block those ports

If you're going to move sshd somewhere else, port 443 is a fine
choice. Rarely blocked, rarely probed by ssh kiddies. It's probed
all the time by malicious web spiders, but since you're not a web
server, you don't care.

Except if you're running a version of OpenSSL that has a vulnerability, you could be inviting trouble - particularly with kiddies scanning for Apache with vulnerable versions of OpenSSL attached by way of mod_ssl etc...
