42's project to build a custom IRC server. IRC stands for Internet Relay Chat, and is one of the first chat protocol on the internet, made around 1988. Twitch still uses an IRC chat nowadays, and a network of servers still hosts thousands of channels.
- You have to develop an IRC server in C++ 98.
- You mustn’t develop a client.
- You mustn’t handle server-to-server communication.
- Your executable will be run as follows:
./ircserv <port> <password>- port: The port number on which your IRC server will be listening to for incoming IRC connections.
- password: The connection password. It will be needed by any IRC client that tries to connect to your server.
- The server must be capable of handling multiple clients at the same time and never hang.
- Forking is not allowed. All I/O operations must be non-blocking.
- Only 1 poll() (or equivalent) can be used for handling all these operations (read, write, but also listen, and so forth).
- Several IRC clients exist. You have to choose one of them as a reference. We chose irssi.
- Your reference client must be able to connect to your server without encountering any error.
- Communication between client and server has to be done via TCP/IP (v4 or v6).
- Using your reference client with your server must be similar to using it with any
official IRC server. However, you only have to implement the following features:
- You must be able to authenticate, set a nickname, a username, join a channel, send and receive private messages using your reference client.
- All the messages sent from one client to a channel have to be forwarded to every other client that joined the channel.
- You must have operators and regular users.
- Then, you have to implement the commands that are specific to operators.
Clone the repository in the location of your choice, go inside it, then compile using make command:
cd ft_irc
make
Then, launch the server. Usage:
./ircserv <port> <password>
Then, launch your irssi client, and connect to the server (locally if you want to test on the same machine).
