As in the ssh login failed after the ping failed or did the ping find the
host and you still had an ssh failure. The error I remember you receiving
(long trimmed out of this thread) had suggested to me that your machine
was not finding the other machine in DNS lookup (or maybe found an inaccurate
address) that cleared by the time of the next lookup. If the destination
machine's actual numeric address does not change I'm not sure how the DNS
lookup could be wrong unless it got stale with a timeout.

So much for that idea, eh?
