Can you go back through your logs to see if there were any incidents of
any note in the hour before the first fubar? Check messages, last and
secure.

This is a good question from you Tina. Perfectr for this list. If you
don't mind riding it out with us, we just might get you through it and
learn a thing or 2 ourselves in the meantime.
What concerns me here is that it was working and then suddenly went south.
You didn't do any changes to the systems at all, including running up2date
or adding/deleting users?

Thank you. Troubleshooting is much easier if you've done some homework.
You're problem isn't in rsync, it's in sshd and the auth keys, which
you've identified. What happens if you set the keys and auth to RSA? If
this works, we've narrowed it down to the ssh daemon.
I had a similar issue once, where I set a new set of keys and just cut
and pasted them into the server. The problem was that the newline breaks
on the console were also pasted, breaking the keys. The fix was to delete
the newline breaks, and !whammo! I was back in business.
