Lab 2

Objective

• Introduction to Sockets and socket programming.
  

Lab Component

• Using FireFox go to http://beej.us/guide/bgipc/output/html/multipage/unixsock.html. Here you will find a simple local domain example of client and server. The example will put up a server which will echo back to the client any message sent to it.
• You will need to compile both files and execute them in separate windows.
• Modify the above example, to be network capable. This will require you to use AF_INIT domain.
• Try it on your local machine 127.0.0.1 which is the default local IP address of the host adapter. localhost should also work.
• Try connecting to another students machine.
  

Reward Requirements

• Annotate the code from the above 2 exercises. The annotations should accurately describe what each section of code does and why it does what it does.
• Print it and submit it.
