Somoene mentioned to me that they don’t have a irc client today. This is no excuse, so of course I thought I will write a article on how to connect to a IRC channel through raw connection. For this example I am using netcat (nc) but you can also use telnet or similar.
First thing to do is to Connect. For example sake, I am using irc.freenode.org using port 6667.
nc irc.freenode.org 6667
If sucessful, it migth reply you with a while about how your not authenticated and such, or some servers might not do that. You now have a short amount of time before it times out, so hurry. Next you need to tell the server who you are.
Now set up the usermodes and your name
user janitha 8 * janitha
Now you should be greeted with the irc server’s welcome banner and information, or if there are non set it might just do nothing. Depends on the server.
Now to see what channels it has to offer. Of course if its a big server that you know have thousands of channels, might not be a good idea since it will take a while dumping all the channels and information.
Its time we join something now. I am gonna go sip some coffee at our coffeestation channel (you can find me there anyway)
To see who else is on the channel once you join, you can do the following
And the most important thing is to be able to talk in a channel
privmsg #coffeestation hello world!
Or you can private message a individual now that you know the names
privmsg someperson hello, whats up
Now to get out of the channel you can use part, just like in a normal irc client
And now to finally quit
You should also know of ping, which is to keep notified that your still there. Do this from time to time. It should return back with a pong.
The other useful thing that comes to mind is whois, again works just like a normal irc client
Thats about all I can remember now. You can always hit google and look for more information. Below is a example of a full conversation starting from connect to quit. The commands I sent to server are in bold.

Hope you find this informative, although its highly unlikely that a need arises to use a irc when you don’t have a irc client. Feel free to add anything in comments.
