Leave an ssh session open and su'ed to root then change the setting:

        PasswordAuthentication

to 'no' in /etc/ssh/sshd_config.  Then restart sshd (probably in that ssh
session I mentioned above).

Also, I've started doing some short talks (5-10 minutes) at each NewTLUG
meeting.  The next one is going to be an SSH primer.

HTH,
