One problem with this is that then you can't run X on your system any 
more.  If you want to run X, but still close port 6000, there are two 
options, both of which work:

The wrong way: Use IP-Tables to turn off port 6000

The right way: Start X with the "-nolisten tcp" option.  

In either case, you will still be able to use X on the box, but outside 
systems will not be able to contact the X server.
