x11 Apps crash connection refused by server

[Sini]

Hello,
I'm fairly new to Apple and trying to get some of the open source network management tools up and running within OS X. I have installed Open Darwin, X11, and the Apple Dev kit. When i try to launch an application such as ethereal for instance, it dumps and says the following:
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

(ethereal:1964): Gtk-WARNING **: cannot open display:

I've added export DISPLAY=0.0 to my .profile but that doesn't seem to help.

Please Help

Are you running X11 through 'sudo'? Anyhow, The usual fix is to delete the .Xauthority file in your home directory and re-create an empty file:

cd
rm .Xauthority
touch .Xauthority

Then:

1- Start X11.

2- Start ethereal from an xterm in X11 with:

sudo /sw/bin/ethereal (if installed with fink)

Or you could write:

if [[ -z $DISPLAY ]]; then
  export DISPLAY=:0.0
fi
