• 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. Your reference client will be used during the evaluation process.
• 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 channel operators:
    • KICK - Eject a client from the channel
    • INVITE - Invite a client to a channel
    • TOPIC - Change or view the channel topic
    • MODE - Change the channel’s mode:
      • i: Set/remove Invite-only channel
      • t: Set/remove the restrictions of the TOPIC command to channel operators
      • k: Set/remove the channel key (password)
      • o: Give/take channel operator privilege
      • l: Set/remove the user limit to channel
• Of course, you are expected to write a clean code.
