It is frequently more enlightening to turn on debugging on the server
side.  You can often spin up sshd on a high-numbered port for testing:

  /usr/bin/sshd -d -d -d -p 2222

This will not daemonize and will only handle one connection attempt.
Run that in one window, and then attempt to ssh into the host from another:

  ssh -p hostname
