I inherited a Redhat Linux system to administer. While I'm nobody's Sysadmin (network is my thing) - I do know that direct login using "root" is generally a no-no. Right? That's how the previous owner would SSH to the box - using "root" for user name. How do I prevent direct access with "root" and but make sure I don't log myself out of any essential access. My guess is first I can log in with my own UID and su to root and make sure that is all cool. (It is.) But then how do I prevent direct root login?
