Gtk-WARNING **: cannot open display: -- help?

[Matt32]

Hi...

Running Ethereal (compiled from darwinports)... when I'm logged in as Admin, I can open up xterm in X11 and run it as 'sudo ethereal' and that's fine. However, I rarely use my Admin account, and it's a pain because I have no need to use Ethereal while I'm logged into my Admin account. Soo... in my normal account, in X11, I can't 'sudo' anything because I'm not in the sudoers file (which is as it should be). So I use 'login' to login as Admin, but when I then try to use 'sudo ethereal' it gives me this error:

Gtk-WARNING **: cannot open display:

I have found this thread http://forums.macosxhints.com/showth...9&page=3&pp=20 but it wasn't much help. The advice there was very confusing (I'm a Unix newbie.. ).

Any help would be really appreciated!

Many thanks,
Matt.

If you' want to run 'sudo ethereal' from Terminal.app and you're using bash, write in your ~/.bash_profile file:

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

Then, first make sure to start X11 before you run 'sudo ethereal'.
