    How do they crack your IRC client? You have to be using it.

    Also, the standard rule of thumb, is that if someone gets onto your system
    as a user, they can get on as root. A system is far far more vulnerable to
    insiders than outsiders.

    ]my distro is a "Linux Professional", I think means RedHat 8.0 more ore less;
    ]moreover:

    And you run at which runlevel--3 or 5?

    Why is nfslock running if nfs is not running (runlevel 3)
