===Configuring a Service===
*A common, (if somewhat blatant, way ) to try to hack into a machine is to try to ssh as '''root ''' and brute-force the root's password.
**The root user always exists, meaning the attacker doesn't need to try guessing what user names are on your system.
**And if they can get access to root, they can do anything.
