If you're running the app locally, rather than running it on some other 
machine with DISPLAY set to point to your desktop machine, if DISPLAY is 
set to ":0.0" that shouldn't matter, as it'll be connecting via a 
UNIX-domain socket rather than via a TCP connection to port 6000.

If you *are* running it on some other machine, of course, your machine's 
X server has to be listening on port 6000 - and you might have to use 
"xhost" locally to get it to accept connections from the remote machine 
in question.

If you're running Ethereal locally as root (to enable capturing on 
platforms where that's required), you might also have to use "xhost" to 
allow connections from root.
