Keith,

   Further poking and proding tells me that the RSA/DSA keys got out of sync.
So I've taken down Mick Bauer's "Building Secure Servers with Linux" to
remind myself exactly how to run ssh-keygen. I'll regenerate the keys on all
three hosts, then copy them around on the USB thumb drive. That should fix
things up. If not, I'll go back to Google.

   Oh. OK.

   I used to go to the clinics. Perhaps I can make the time to do so again.

   One of the things I learned this weekend is when a full upgrade (including
''--install-new'') puts sendmail on a system running postfix as the MTA, the
mail system _really_ blows up until a couple of files are replaced from the
backup tape and the link from /usr/bin/sendmail to /usr/sbin/postfix is
recreated.

Thanks,

Rich
