I'm having trouble using the display connection facility under X.

I have written a very simple X-windows application, most of which is out of a
book and which uses a "-d" option to select a display.

Attempting to use a display other than ":0.0" produces an error.
e.g. demo -d spike:0
	 Invalid Display: spike:0

Even though I'm on spikes xhost list and xclock -display spike:0 works fine.

My code is so simple I can't understand what is going on !!

The really odd thing is I got hold of the source to xclock and recompiled it
using cc xclock.c -lXaw -lXmu -lXt -lX11 -O -lm and now it doesn't work for
remote connections !! (it works fine without the -display option).

I hope someone can help.

Ian
