Assuming you know the username then maybe. It depends on the strength of the users password. If they are only using private keys with passphrases then you probably won't be getting access that way with any account. > > If they can hack the root they can defenatly hack a user account too. > So i dont see any meaning of disabeling it. If they can hack root they own the system and can do what they like. By disabling root you remove the option of this happening. Instead they have to try and compromise a user account. Once they compromise the user account, they then have to gain root access (assuming that is their goal). Why bother with the hassle. There are plenty of machines out there already with weak root passwords. If a hacker really wants into your system he will find a way. Chris
