SSH Login Shell

[Rick Woodring]

I cross-compiled DropBear as a single library, installed it to my development system, generated RSA and DSS keys (to their default location/filename), and started the SSH server with the command shown below.  When I execute "ssh 10.0.1.34 -l root" on my RedHat 9 box to connect to the board, I am informed that the authenticity of my board cannot be verified as asked to continue connecting to the machine with RSA fingerprint ______________.  I tell it yes and I am prompted for the root password.  When I type it in, I see an error message "user 'root' has invalid shell, rejected" on the development machine.  Do I need to create a config file in /etc that tells dropbear what shell to run on login?
