We've received reports of the message "Server refused user authentication protocol" when attempting to connect to an ssh.com server (version string "SSH-2.0-3.2.0 SSH Secure Shell (non-commercial)") with compression enabled. Connection is fine when compression is disabled.

In the code, this message corresponds to not receiving the right response to a "ssh-userauth" service request in SSH-2.

We've also heard of problems with port-forwarding with compression enabled.

Update: We believe that the bug in talking to ssh.com 3.2 with compression enabled has been fixed as of 2002-08-09. We've had one confirmation.
