Peer Chat

A Peer to Peer(P2P) Chat Application in C using TCP Protocols for connections within a defined closed set of users.

Adding Users

The USERS.txt file defines the closed set of users that you want to chat to. The first line should be the total number of users followed by data of users (IPv4 Address and Port).

Compilation of Source Code

Compile the source code using the following command:

gcc -o app app.c

Running the application

Run the application using the following format:

./app <YOUR PORT>

For testing on local machine

For testing on a single machine, run the executable in multiple instances of the terminal. It would act similar to multi-computer network.

For example (local machine):

Terminal 1

./app 3000

Terminal 2

./app 8000
