xhost run from within the Xnest server....
"access control enabled, only authorized clients can connect"


However, I ran the above on another system and that one won't let me
connect to the Xnest X server.   Digging....

Ok, the following script worked (taken from 
<http://dot.kde.org/988934998/988942946/988947089/> with a small fix.


==== begin ====
#!/bin/sh
MCOOKIE=$(mcookie)
xauth add $(hostname)/unix$1 . $MCOOKIE
xauth add localhost/unix$1 . $MCOOKIE
#startx /usr/bin/startkde -- /usr/X11R6/bin/Xnest $1
xinit /usr/X11R6/bin/xterm -- /usr/X11R6/bin/Xnest $1
xauth remove $(hostname)/unix$1 localhost/unix$1
exit 0
===== end =====

Make the script executable and run it with the display to use for
the Xnest server (e.g. :1) as its only argument.  So if you
call the above script "nest", then run

./nest :1
