1 What is IRC :

Internet Relay Chat ( IRC ) was born in August 1988 to replace Bulletin board system(BBS). The protocol was created in Finland by Jarkko Oikarinen. IRC was once the most popular method of online communication and is now replaced by other more modern ones.

IRC is a chat protocol that is used to power various chat networks. Chat networks powered by IRC are known as IRC themselves. Unlike chat networks like Yahoo Messenger or Facebook, IRC is highly decentralized in nature, and not controlled by a single company. Anyone can setup a IRC server on decade old hardware. And there are literally hundreds of IRC clients available for every possible platform (Windows, Mac, Linux, Android, iOS, web based, and much more).

Even though popularity of IRC has been dwindling, but still IRC holds relevance because most of software, hardware communities, and some forums (especially open source and hacking communities) use it for providing a sort of informal support of their products, discussing amongst themselves, and in general helping out the users.

With this part we have ended “What is IRC?

2 Technical Information:

Now that we know What is IRC, let’s dive a little into technical aspects about it. I won’t be going in too much detail. But would like to give enough information so that you have a good understanding about its architecture and know enough commands so that you can even work on an application that does not have a GUI. Feel free to refill your coffee cup.

2.1 Client / Server Model:

IRC is a multichannel, multiuser, real time chatting system which uses a client – server architecture. It also offers the ability to transfer files from one user to the other. The chat rooms here are called Channels and one to one communication is called Private Messaging.

To use IRC services we require an IRC client software to connect to a IRC server. There are lots of graphical clients available for free but earlier you had a command line interface and used to manually type commands to perform any action. Anyway the commands still hold some use which I will explain in detail in a while.

There are thousands of servers which cater to different categories. The server part of the IRC is easy to implement and way easier to maintain. To find appropriate channel you can look through many different server-lists.

Best thing about Chatting on IRC is that you don’t have go through the process of registering etc., all you have to do is enter a channel and choose a nickname and you can start chatting.

2.2 IRC Commands:

These days all the IRC clients are GUI based and you can point and click your way through the interface. But there are some things which are done better and faster using commands. So here is quick guide to most of the basic commands that you might want to know as a client. However, it is possible to do everything without using any command. So, if you don’t want to bother yourself with technical jargon, feel free to jump this section.

The commands are to be entered in the text field where you would normally enter text to chat but with a forward slash prefixed for example ( /Command ). See screen shot below.

Connecting to a server:

Every server is known by a hostname. Lets take an example of DALnet its Hostname is irc.dal.net. Just type the /server followed by the Hostname.
Example:
/SERVER irc.dal.net
This would connect you to the Server.

Finding channels:

Now your connected to the sever which provides you with channels. To get the List of channels available on the server type /List. This will return you the list of all the channels available on the server with the details of each channel like Name, Users, Topic.
Example:
/LIST

Connecting to a channel:

Once you have the channel name, all you have to do to connect to it is type /join followed by the channel name. If the channel exists you will be connected to it otherwise a channel will be created with the same name.

Example:
/JOIN #MyIRC888
Because this channel does not exists it will be created and you will become its operator.

Getting list of names of people in a channel:

Once you are connected to a network it will show all the user names if you are using a GUI application. If you are using a command line application then just type /names followed by the channel name.
Example:
/NAME #MyIRC888

Other useful command is to use /whois followed by the name of the person who’s details you want to get.
Example:
/WHOIS fire88

If you want to change your nick name try the command below.

Example:
/Nick MyNewNickName

Now your nickname will be changed to “MyNewNickName”.
Setting your status to away and quitting:

Away:

Want you explain why you will be not available for a while type /away followed by your message .
Example:
/AWAY writing a long article on What is IRC, back in 15 days

When you get back just type /AWAY

Quitting:

There are two methods of quitting: quit and leave. Quitting will exit IRC, while leaving is meant for exiting for a channel.
To quit just type /quit followed by your message which is optional.
Example:
/QUIT Woo Hoo! Article done. Need to get drunk now!

To just leave a specific channel type /leave followed by the channel name .

Example:
/LEAVE #MyIRC888
Starting a private conversation:

To initiate a conversation with someone use /msg command .
Example:
let the persons nick name be Friend to whom you want to send a private message and interact with in this whole example.
/MSG Friend what’s sup ??
if you are using a GUI application (which most probably would be the case) then some of those would open a conversation window with other person, like most of the modern chat messengers do. These windows are known as a query window. Now to send a private message if query window did not open would become a cumbersome because you would have to type /msg again and again . Here is when /query command comes in. If you want to open up a separate query window then type /query followed by the persons nick name.
Example:
/QUERY friend hey, how is your day going .

Direct Client Communication(DDC):
If the server is having a problems and lagging etc., then you can bypass the IRC server and continue having a private chat with the person. For this you will need to use DDC command.
Example:
Start DDC:
/DDC CHAT friend
then you can send messages using the /msg command as shown above.
End DDC:
/DDC CLOSE CHAT friend

File Transfer on IRC:
To transfer a file we use the same DDC command but with different arguments.To start a transfer use /ddc send. Then the person will get a notification and if he accepts if then the transfer will occur.

Example:
/DDC SEND friend C:\Users\Icrus\Desktop\test.txt

Depending on the client he/she will get a notification. If it’s a GUI application then a dialog box will open up where he/she has to accept the file in order to get it. Else he will get a text saying that I have sent a file using DDC.

To accept is via command he/she has to type the following
/DDC GET yourNickname.

For Further Exploration :

Use help command for further exploration. Just type /help will bring up a list of all the commands that can used are displayed in an alphabetically arranged order.

Example:
/HELP

To get more specific information on a command that your are interested in type the command you are interested in front of /help .

Example:
/HELP SERVER
