That would seem to reduce the difficulties associates with logging
random users' passwords. However, that makes me wonder what the point
is -- are you just curious as to how random crackers start their
dictionary attacks?
Besides, if you're only SSHing on the lan, you might be better off
from a security standpoint by just dropping foreign-IP packets to 22
and whatever SSH port you actually use. If there is no legitimate
traffic, why even give attackers a login prompt?
