I see now that I misunderstand what X11 and XDMCP are. I was wondering to
myself how I was going to setup putty to tunnel this and the answer is I
won't. I used the following command in the Cygwin bash shell to make the
connection described in my original post:
XWin.exe -query 192.168.0.9
Can I use Cygwin to make a XDMCP connection?
