[BlueOnyx:03606] ssh hangs after password

[Gerald Waugh]

Excuse the cross post, looking for an answer.
ssh into the server, enter password, and hangs.
Tried with putty and a Linux PC terminal session,

Can't even ^C out, have to close the terminal session.
here is a debug output of the connection.
