Error with firestarter.
 

I opned a shell and logged in as root but when i type firestarter i get this.

root@User:/home/User# firestarter
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified


(firestarter:887): Gtk-WARNING **: cannot open display:

Any idea how to fix this ?

Fixed error.

If you post your solution, you might help out someone who has a similar problem in the future.

Although I am not positive and I would appreciate the original poster posting their answer... I have run into the problem myself in the past and found the following works:

xhost +127.0.0.1

You must run this from the local machine. Usually you see this only when trying to open a window on a remote box or with some programs that don't play nice. Sorry, I don't know exactly what these programs are doing but I suspect they are changing their effective user id too early. :D

Here is how you solve that problem

As user type: $xhost +
As root: #DISPLAY=localhost:0.0

To go back to user do it inverse.
