Well, i've ruled out reverse DNS, as one of the machines didn't have a
reverse DNS entry, and the other did.  (and because of that, one of them
spouted an error about rDNS, and the other did not) But now they both
have proper rDNS entries, and that made no difference in time to get a
password prompt.

The /etc/sshd.conf is below.
