[clug] What holes do I punch into Windows XP home firewall for aremote X session? [SEC=UNCLASSIFIED]

[Roppola, Antti - BRS]

As per the other email, you can use netstat to see what's listening. 

I have also used the XP firewall exceptions to allow specifc
executables.

Find out what .exe in CygWin accepts X connections and put the exe in as
an exception,
that way you don't need to keep track of what ports are being used.

I have configured a desktop Ubuntu Linux box for remote X with XDMCP,
and I can connect and login fine over the network when I boot my
notebook in Ubuntu, but not when I am trying to connect with Cygwin/X on
Windows XP.  On XP, I can get the welcome screen OK but after I login
the session freezes before I can get a desktop.  I have discovered that
disabling the Windows firewall allows me to login fine, so it's clearly
an issue with some port being blocked that Ubuntu/Gnome wants to talk to
before setting up the desktop.  I don't want to leave Windows Firewall
off all the time -- does anyone know the specific port that is the
hangup, and what service the Ubuntu box is trying to connect to?  If I
know I can add an exception.
