1) Write a server and a client Your server can do anything except echo and KnockKnock. Have your server open a file and write information about each client that attaches to it. Have the server append to the file, rather than make a new one every time. 2) Have your server open any available socket and then print out what socket you were assigned. 3) Have your client take input from the keyboard for the socket and for the data to send to the server, so you will be able to use the same client for all the servers.
