I am wanting to be able to log-in and "su" when required from my normal account via ssh but I don't want to allow root to be logged in to directly. This means that at least two passwords are required to become root. I have been fiddling with the config file for a while but I have not suceeded, I can only block out root access completely both direct and through su.
Any help appriciated.
Have you Tried GOOGLE
the second link should give you this advice
Disabling root SSH logins. Edit the /etc/ssh/sshd_config file and set the PermitRootLogin parameter to no.
I had but their was nothing of help. I am still where I started, no root login and no su or root login and su. I shall have another look tomorrow, concentration is not at its best so I'm going to bed but thanks for the help.
