  • 8. Terminology● Network● Client● Channel● Operator● Channel Operator● Commands
  • 9. Network● Consists of at least one server, but can consist of many servers in a spanning tree.● What your client connects to so that you can chat with others.● Each server in the tree is running IRC daemon software.● In a multi-server network, two users dont have to be on the same server to chat with one another.
  • 10. Client● Anything that connects to an IRC network that isnt a server.● Includes your chat program and bots as well.● Each client must be uniquely identified.● Messages to clients are transmitted through the server (no need for direct connection).
  • 11. Channel● A "room" that users can join and chat as a group.● Messages sent to a channel are seen by all who have currently joined that channel.● Channel names are unique and usually prefixed with hash character (#).● Channels are created when the first user joins the channel and destroyed when the last user leaves.
  • 12. Operator● A client with special privileges on a network.● Help maintain the network by adding and removing servers; adding, removing and banning (if necessary) other clients, etc.
  • 13. Channel Operator● A client with special privileges on a channel.● Help maintain the channel by removing disruptive clients, setting the topic and changing channel settings (like keywords).● If you are the first to join a channel, you are often made its operator automatically.
  • 14. Commands● Commands are how clients interact with servers.● Prefixed with a forward-slash (/).● They often take one or more arguments.● On most networks you can issue the help command for more info about any command ○ /help ○ /help <command>● Can usually run commands for one channel while in another by specifying other channel.

  • 20. Register with ChanServ● Like NickServ, ChanServ is a service that helps maintain channels on IRC networks.● Registering your channels with ChanServ links you with the channel and provides a mechanism for recovering the channel should it be taken.● Usage: ○ /msg ChanServ register <channelname> <password> description_of_channel● Record that password in a safe place!
