Those are the server's own keys that it uses to identify
itself to the client.

I assume you've already got a ~/.ssh/id_rsa or ~/.ssh/id_dsa
on the desktop computer?  You have to put the .pub public
key portion of that key in /root/.ssh/authorized_keys on the
server, with correct permissions. (Paths may vary depending
on the user setup).  Dropbear exits straight away because it
won't allow a password with -s -g, and there's no public key
it can check.
