ssh trouble checklist

Hi.

There should be a checklist of everything that can go wrong with 
making an ssh connection.

Here's one entry for the list, which I didn't know before, and
  * I couldn't see the problem from the -ddd and -vvv output, and
  * there were no /var/log/* file entries to give hints.

Here's what I did
   sudo kill <pid-of-sshd>
   /usr/sbin/sshd

No good.

Usually I did kill -HUP, but once I just killed sshd outright.

Gotta start sshd this way:
   /etc/init.d/sshd start

At least on Fedora 11.

Below are the observed symptoms.
