Using java

Create a chat client, and chat server. The chat client must be able to communicate with other chat clients on separate computers on your local network. Do not use 127.0.0.1 this will only respond to commands on one machine. The chat server must be able to communicate the client packets to the other chat clients connected. Essentially create a LAN chat room for all available computers that you have.

TLDR: When two people are in the same chat room, you can see all messages each client types on one chat client.

EXAMPLE

Computer1: Runs chat server

Runs chat client

*type something*

>Computer1:Client== Hi there

Computer2: Runs client

>Computer1:Client== Hi there
