Introduction - What is IRC?

In simple terms, IRC is a Chat program that allows users to communicate and exchange files. Users have to connect to an IRC Server and then join the Channel (similar to chat rooms) of their choice for discussion and group communication.

In this tutorial, we will cover how to connect to our IRC Channel (#HackIT-Lobby) which is available on Server. We will be using ChatZilla, which is a Firefox extension for IRC.

  • After connecting to a server, the next step is to connect to a channel.

  • In our example, we will be connecting to a Channel named "HackIT-Lobby".

/join #HackIT-Lobby

  • Note, in IRC, the channel names are preceded with a "#" (hash) symbol.

  • A new tab will be opened as shown below:



  • Congratulations, you have successfully connected to our IRC Server.

  • Free free to shoot and share your technical questions and ideas with the HackIT community.

In the next tutorial, we will see how we can register a nick name with the IRC server and authenticate to the server using a nick name and password.

Till then - Happy Hacking :)
