Indeed, for a personal server that only I ever log in to, one of the
first things that I do is add "AllowUsers wollman" to
/usr/local/etc/ssh/sshd_config.  That's just a belt-and-suspenders
thing, though, to make sure that I don't fat-finger the password file
or something.  I generally ignore the ssh "invalid user" complaints --
I have a modified version of /etc/periodic/security/800.loginfail that
filters them out -- because they're totally irrelevant and have no
impact on security.  That allows me to pay attention to the (very
occasional) password failures on real user accounts.
