There are a number of possible problems, including:

* You might not be able to get a route, especially if a home router is 
doing NAT.  Try traceroute to see if you can get a route all the way to 
your destination IP address.

* Some ISP or firewall might be blocking the port number, or a home 
router might need to be configured to send that port to the desired 
machine.  Try "telnet" to see if you can connect to the port manually.

* If your second program exits, it might be exiting before it finishes 
the TCP protocol to send.
