The message
ssh: handshake failed: ssh: unexpected message type 3 (expected one of
[6])
is from the spate of problems/fixes due to the recent rekeying rewrite.
For the original message, it looks like the server hasn't enabled
keyboard-interactive, but it's hard to tell. Easiest is to set
debugHandshake = true and see what the log messages say.
