Arguements aginst doing so are generally based on the "'security by
obscurity' is not security" concept.
That argument _is_ 'technically accurate'. <grin>
Moving sshd to a non-standard port does _not_ do anything to make the
system any more secure.
Of course, as long as one understands that that _is_ the case, and
is doing it for 'some other' defensible reason -- such as to eliminate
