If you enable batch mode (option batch ...) before opening connection, the password prompt is cancelled in 10 seconds.

Hi,

I need to connect to a server which is configured to prompt for password when public key authentication fails. However, I am not issued the password. At times, when the server is busy, it throws public key authentication failure even though the ppk provided is correct. Then it prompted me for password. As I am using scripts for connecting, the script will just hang there and wait for password input.

Is there anyway that I can force this connection to close?

Please advise.
