I haven't read through the code, but something you might try if you
haven't already just to rule out other potential problems:

- Try to use the system command ping(8) from a command shell like bash
or tcsh, as the the same userID as your program will be running at:

   (tcsh shell prompt)>  ping -c 3 www.google.com

If that doesn't get a response, you likely have a firewall issue.

Just a thought.
