Why can’t I log in directly as the root user to VPS v2?
For security purposes, direct root logins using the username root and the root password are not permitted on your VPS v2. Many administrative tasks can be accomplished by logging into the VPS v2 account as the administrative user. Once you have logged in as the administrative user, you can then use the su command to become the root user. See the VPS v2 User’s Guide for more information on the different protocols as well as the appropriate user to connect with.
