search unix xhost
Just in brief, xhost controls which servers can access your X-terminal. Normally, only the localhost, the computer attached to the display can access the local X-terminal server. It may be useful in some circumstances to also allow other computers access to your display. An example is when you telnet or ssh to another computer and run a program there that needs to access your screen.

Some useful commands:
    xhost +                this command allows everyone access to your local screen
    xhost +name        allows computer with name 'name' access to your local screen
    xhost -name         revokes access to computer with name 'name' access to your local screen

BTW: you can also type man xhost and this wil give a you (on most Unix computers) a manual page for the xhost command.

Hope this helps.
