What you probably want is: PermitRootLogin without-password This lets you do key pair logins but not password logins as root. You should also check the permissions of the .ssh directory. Other things to check - is sshd running? Does your firewall allow incomming ssh connections? You should check your logs to see what kind of error message you get when you try to log in. It is more secure to sent PermitRootLogin to no, ssh as a normal user using a key pair, and su to root. But this is not always possible when automating some applications. If you are only doing console logins, please consider disabling root logins in ssh. Mikkel -- Do not meddle in the affairs of dragons, for thou art crunchy and taste good with Ketchup!
