I'd just like to chime in here that I was experiencing the same problem as madhurikl. I unexplainedly could not establish a connection on my SLES11 SP1 remote hosts. The above code snippet is useful for debugging exactly what the problem is. In my case, SLES was rejecting the authentication.

error021code = -18
error022error_name = LIBSSH2_ERROR_PUBLICKEY_UNRECOGNIZED
error023error_string = Authentication failed (username/password)

For whatever reason, the Net::SSH2 methods auth and auth_password just don't work on SLES11. However, auth_keyboard works perfectly fine. Problem solved. However, I suspect this should really just be a lesson to both of us to start using keys for authentication in the future.
