This project is an implementation of an IRC server built in C++. It adheres to the basic principles of the IRC protocol, allowing multiple clients to connect, communicate in channels, and execute various commands such as joining channels, sending private messages, and setting topics. The project was created by idelibal and mortins-.

• User Authentication: Password-based authentication for clients.
• Channel Management: Create, join, and manage channels with features like invite-only, user limits, and channel keys.
• Messaging: Support for private messages and broadcast messages within channels.
• Server Administration: Operators can manage channels and users with commands like KICK and INVITE.
• Command Support: Implements key IRC commands such as PASS, NICK, USER, JOIN, PRIVMSG, MODE, TOPIC, QUIT, and more.
• Signal Handling: Gracefully handles server shutdown via signals like SIGINT and SIGQUIT.

• A C++ compiler supporting C++98.
• Basic understanding of networking and the IRC protocol.

1. Clone the repository:

   git clone https://github.com/dlbltv/ft_irc.git
   cd ft_irc

2. Compile the project:

   make

Run the server executable with the following syntax:

./ircserv <port> <password>

• <port>: The port number on which the server will listen.
• <password>: The password required for clients to authenticate.

Example:

./ircserv 6987 my_secure_password

Clients can connect to the server using any standard IRC client (e.g., HexChat, irssi). They must use the password specified during the server launch.

NetCat (nc) can also be used to test the server. Here is an example:

1. Start the server:

./ircserv 6987 my_secure_password

2. Open a terminal and connect using NetCat:

nc localhost 6667

3. Authenticate with the server by typing the following commands in the NetCat session:

PASS my_secure_password
NICK mynickname
USER myusername 0 * :My Real Name

4. Once authenticated, you can use other IRC commands like:

JOIN #mychannel
PRIVMSG #mychannel :Hello, World!
QUIT :Goodbye
