Wrt your netstat output, the listening is being done on ports 81 and 8080 respectively. the "newgort:0" stuff in the foreign address column means that the process is listening on the IP address which newgort resolves to (probably your network card). "0.0.0.0:0" is the common one there, which means the process is listening on all interfaces. "127.0.0.1:0" means the process is only listening for connections from your local machine. With a particular IP address or hostname in there, it means the process is only listening on that particular network interface.
