My SSH connections worked well, but from last week SSH from my laptop to my board refusing connection. I can make a SSH connection from the board to laptop, but not vice-versa. I tried that with my user and root user and had same issue.

My Laptop is an Ubuntu 12.10 and my board is a Debian 6.

Here is the verbose output of SSH:
