Distributed Systems: Introduction

A simple UDP client and server:

• client.c: example client code, sends a message to the server and waits for a reply
• server.c: example server code, waits for messages indefinitely and replies

Both use udp.c as a simple UDP communication library.

The Makefile builds client and server executables. Type make to do this.

To run: type server & to run the server in the background; then type client to
run the client. You will likely then want to kill the server if you are done.

If you want to run these on different machines, you'll have to change the client
to send messages to the machine the server is running upon, instead of localhost.
