In ds10, you will write a networking program that will listen on a port number specified in the command line and prints out the message that is being sent to that port continuously.
To compile and run, use the following commands from a terminal on a Linux machine:
$ make
$ ./ds10 port_number
To send a command to your program, you could access the url 127.00.1:port_number/message from your web browser which will send an HTTP packet to your program.
