When you use ssh, you should use -X or ForwardX11.  Then it will set 
DISPLAY correctly and remote X clients will display locally.

If you set DISPLAY in the usual way the remote clients will try to 
contact your local server on port 6000-ish, which is the problem you're 
having.

0.0 is the display number.  Usually the first X server to run is display 
0.  .0 is the left screen and .1 is the right (if you have two).  If you 
run another server it will be display 1, and will use a different port 
than 6000.  But X will probably figure out the right port for you.  (And 
you don't need to worry about it at all if you're using X11 forwarding.)
