-/**
- * Very slightly more complex than example1. 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 localhost 2317
- * 
- * If you're sophisticated you can contact the instructor's computer
- * while running this program.
- * 
- * telnet <ipOfServersLaptop> 2317
- * 
- * And have him display the socket pairs he got.
