UDP Echo Server

This lab is intended to give an introduction to using UDP sockets.

Exercises

1. Make sure that you have completed the work specified for labs 04 and 05.
2. Download this IBM tutorial. Read through section 2. Then, work carefully through section 5, building both UDP echo server and UDP echo client programs. Note: You should look only at sections 2 and 5; the other sections are concerned with programming in Python and are not relevant to this module.
3. Write a simple Makefile to automate the building of the UDP Echo Server and UDP Echo Client programs. Build and run the programs. You should be able to execute the programs on the same machine, using the localhost address 127.0.0.1. You should also be able to execute the client and server programs on different machines, using the relevant IP address of the server's host.
