Configuring Root Logins

If you want to give someone permission to login directly to the root login account via Secure Shell, you can define three methods of control in the sshd2_config file:

PermitRootLogin     no

This will disable all logins with root privileges. To enable root logins with any authentication method, use the following setting:

PermitRootLogin     yes

You can limit the authentication methods by using the following setting:

PermitRootLogin     nopwd

This allows root logins only when an authentication method other than password is used.

It is also possible to create a separate subconfiguration file for root. See Defining Subconfigurations for more information.
