This is charateristic of a connection being dropped by tcpwrappers.  Check
wherever ssh is logging to (possibly /var/log/authlog) and try adding
"sshd: 127.0.0.1" to /etc/hosts.allow (or wherever your tcpwrappers is
compiled to look).

Oh, and consider upgrading the the sshd, it's pretty old and possibly
vulnerable.

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
