Is there an X server running on this display?
The "localhost" in there means that a TCP/IP connection is established.
Normally your own X server runs on something like ":0" -- which means
"local" transport -- and TCP/IP connections are refused. 

For example on my Debian system, the file /etc/X11/xinit/xserverrc
(which is read by startx) contains the following:
exec /usr/bin/X11/X -dpi 100 -nolisten tcp

The last two words should be self-explanatory.

This could indicate that in fact no X server is listening on 
this DISPLAY.

I quickly tried the following:

$ xauth list
....
# export DISPLAY=:0
# xauth add ....
# xmonui -display :0 | xmond

There are no error messages, but unfortunately no other output either.
I've never used these tools, so I have no idea how to make them display
something.

hope this helps,
