SSH password dialog could not grab the keyboard input.

睿智2012

SSH password dialog could not grab the keyboard input.
This might be caused by application such as screensaver, however it could also mean that someone may be eavesdropping on your session.
Either close the application which grabs the keyboard or log out and log in again to prevent this from happening.
