/**
* Very slightly more complex than example1, further modifying example2. The
* only thing this does differently is introduce a loop into the response, so
* you don't have to restart the program after one response. Also, it prints out
* the socket pair the server sees. Run the program via telnet several times and
* compare the socket pairs.
*
* telnet (nc) localhost 2317
*
* If you're sophisticated you can contact the instructor's computer while
* running this program.
*
* telnet (nc) [ipNumberOfServerLaptop] 2317
*
* and have the instructor display the socket pairs received.
