[GLLUG] TCP/IP protocol efficiency

[Mike Szumlinski]

I like the idea of this since I'm not concerned with security in the  
least.  The problem I ran into is that this process works backwards  
from what I need.  It allows the Windows box to push to the Linux  
box, but not reverse.  At least not with my only moderate knowledge  
of Windows.  Is there a way to open up a port like with a netcat-like  
command on Windows?  My cygwin install didn't seem to include  
netcat.  Maybe I just missed it?
