Internet Relay Chat

This project is about creating your own IRC server. You will use an actual IRC client to connect to your server and test it. Internet is ruled by solid standards protocols that allow connected computers to interact with each other. It’s always a good thing to know.

The function is written in C language and thus needs the c++ compiler and some standard C, C++ libraries to run.

First install a client, here we'll use irssi since it is the one we chose to do the project with :

# using apt to install
sudo apt install irssi

# using brew to install
brew install irssi

1. Compiling the program

To compile, go to the program path and run:

make

2. Executing the program

To launch the server, run:

./ircserv [port number] [password]

Connect to the server with a Netcat

nc localhost [port]

Connect to the server with a IRSSI
