1. What is IRC, and how does it work?

IRC (Internet Relay Chat) provides a way of communicating in real time with people from all over the world. It consists of various separate networks (or “nets”) of IRC servers, machines that allow users to connect to IRC. The largest nets are EFnet (the original IRC net, often having more than 32,000 people at once), Undernet, IRCnet, DALnet, and NewNet.

Generally, the user (such as you) runs a program (called a “client”) to connect to a server on one of the IRC nets. The server relays information to and from other servers on the same net. Recommended clients:


2. Some details

Channel names usually begin with a #, as in #irchelp . The same channels are shared among all IRC servers on the same net, so you do not have to be on the same IRC server as your friends. (There are also channels with names beginning with a & instead of a #. These channels are not shared by all servers on the net but exist locally on that server only.)

Each user is known on IRC by a “nick”, such as smartgal or FunGuy. To avoid conflicts with other users, it is best to use a nick that is not too common, e.g., “john” is a poor choice. On some nets, nicks do not belong to anyone, nor do channels. This can lead to conflict, so, if you feel strongly about ownership of such things, you may prefer networks with “services” like Undernet, DALnet, or other smaller networks.

Channels are run by channel operators, or just “ops” for short, who can control the channel by choosing who may join (by “banning” some users), who must leave (by “kicking” them out), and even who may speak (by making the channel “moderated”)! Channel ops have complete control over their channel, and their decisions are final. If you are banned from a channel, send a /msg to a channel op and ask nicely to be let in (see the /who command in the next section to learn how to find ops). If they ignore you or /who gives no response because the channel is in secret mode (+s), just go somewhere else where you are more welcome.

IRC servers are run by IRC admins and by IRC operators, or “IRC ops”. IRC ops manage the servers themselves and, on EFnet and many other networks, do not get involved in personal disputes, channel takeovers, restoring lost ops, etc. They are not “IRC cops.”


3. Talking, and entering commands

Commands and text are typed in the same place. By default, commands begin with the character / . If you have a graphical client such as mIRC for Windows, many commands can be executed by clicking on icons with the mouse pointer. It is, however, highly recommended that you learn to type in the basic IRC commands first. When entering commands, pay close attention to spacing and capitalization. The basic commands work on all the good clients.

Some examples are given below. In these, suppose your nick is “yournick”, and that you are on the channel #coolness.

Your friend “MaryN” is in #coolness with you, and your friend “Tomm” is on IRC but is not on a channel with you. You can apply these examples in general by substituting the relevant nick or channel names.

What you type

What happens

/join #coolness

You join the channel #coolness.

/who #coolness

Gives some info on users in the channel.

@ = channel op, while * means IRC op.

hello everyone

Everyone on #coolness sees hello everyone. (You need not type in your own nick.)

/me is a pink bunny

Everyone in #coolness sees * yournick is a pink bunny

/leave #coolness

You leave the channel.

/whois Tomm

You get some info about Tomm or whatever nickname you entered.

/whois yournick

This is some info others see about you.

/nick newnick

Changes your nick to “newnick”

/msg Tomm hi there.

Only Tomm sees your message (you don’t need to be on the same channel for this to work).

/ping #coolness

Gives information on the delay (round-trip) between you and everybody on

coolness.

/ping Tomm

Gives information on the delay (round-trip) between you and just Tomm.

/dcc chat MaryN

This sends MaryN a request for a dcc chat session. MaryN types /dcc chat yournick to complete the connection. DCC chat is faster (lag free) and more secure than /msg.

/msg =MaryN Hi there!

Once a DCC connection has been established, use the /msg =nick message format to exchange messages (note the = sign). DCC does not go through servers, so it are unaffected by server lag, net splits, etc.

/help

This works in many clients. Try it!

/quit good night!

You quit IRC completely, with the parting comment so that others see “*** Signoff: yournick (good night!)”.

NOTE: When you are not in a named channel, lines not beginning with a / have no effect, and many commands work differently or fail to work altogether.


4. Where to go

You can learn a lot by joining a channel and just listening and talking for a while. For starters, try these channels: #new2irc, #newuser, #newbies, or #chat.

For help with the mIRC client, try joining #new2mirc or #mirchelp. For help with general IRC questions, join #irchelp.

To form your own channel with the name #mychannel (if #mychannel does not already exist), type /join #mychannel. The channel is created and you are automatically made an op.


5. Some smileys and jargon

:-) is a smiley face, tilt your head to the left to see it. Likewise, :-( is a frown. ;-) is a wink. :~~( is crying, while :-P is someone sticking their tongue out. :-P ~~ is drooling. (-: a lefty’s smile, etc. There are hundreds of these faces.

Here are some common acronyms used in IRC:

 brb =  be right back                     bbiaf = be back in a flash

 bbl =  be back later                     ttfn = ta ta for now

 np  =  no problem                        imho = in my humble opinion

 lol =  laughing out loud                 j/k = just kidding

 re  =  hi again, as in 're hi'           wb = welcome back

 wtf =  what the f--k                     rtfm = read the f--king manual

 rotfl = rolling on the floor laughing

6. Some advice

Etiquette Typing in all caps, LIKE THIS, is considered “shouting” and should be avoided. Likewise, do not repeat yourself or otherwise “flood” the channel with many lines of text at once. Be sure to use correct terminology, e.g., “channel”, not “chat room”, and “nick”, not “handle”.

While in a channel, follow the lead of the channel ops there. If you antagonize them, you may be “kicked” off the channel forcibly and possibly “banned” from returning. On the other hand, some channel ops are power-hungry and may kick or ban for no good reason. If this happens, or if someone on a channel is bothering you, simply leave the channel — there are thousands of others.

Registration On many networks. services exist for the registration of nicknames and/or channels. These services vary greatly between networks, but are useually mentioned in the server’s message of the day (MOTD) which is shown when you first connect. You can show the MOTD again at any time by typing /motd in most clients.

THe network’s home page will also detail any services offered on that network.

Nickname registration allows you to “own” a nickname, and prevent others from using it on that network. Consequently, if you try to use a nickname that someone else already has reserved on such a network, you will recieve a warning message from the network, and after a few seconds, your nickname will be changed or your will be disconnected. In the event that this happens, simply change your nickname until you find one that’s not taken. Consult the MOTD or network homepage for details if you want to register your nickname.

Disconnected by /list? If you get disconnected when using the /list command, try switching servers, or else recent channel lists are available on the WWW at http://www.irchelp.org/irchelp/chanlist/.

Harrassment and attacks If someone starts harassing or flooding you, leave the channel or use the /ignore command. For more details, mIRC users see our flood protection page, ircII users type /help ignore. It is a good idea to set your user mode to +i (invisible) to avoid unsolicited messages and harrassment — if you are “invisible” generally only users on a channel with you can determine what nick you are using.

If somebody else is crashing or disconnecting you, see our Denial of Service or “Nuke” Attacks page. You can also log and report abuse when it violates server rules, which you can read by typing /motd.


7. IRC server problems, and choosing a server

At this point, you are ready to “chat” on IRC. For the most part, the commands above should suffice for beginners, but things can go wrong in IRC.

Net splits Networks can become divided (called a “net split”), thus separating you from users you had been speaking with. These splits are often relatively short, though common some days.

Lag A more frequent problem is “lag”, where there is a noticeable delay between the time you type something in and someone else reads it. Choosing a server near you is one way to try to lessen lag. Lag can be measured by using the /ping command (see the commands section above). Once you find a better server, the command for changing servers is /server server.name.here.

Server Lists On most clients, typing /links gives a list of servers on your current net. Use this command sparingly, no more than a couple times in a row, or you may be mistaken for a “link looking” troublemaker.

Ping? Pong! mIRC users: Ping? Pong! in the status window just means your server pinged you to make sure you were still connected, and your client automatically replied with a pong. Don’t worry about these.

Reminder about DCC chat The /dcc chat command can be used to establish a one-on-one connection that avoids lag and will not be broken by a net split! Check your docs for usage info. In most clients, you can set up a DCC chat connection by both typing /dcc chat nickofotherperson. To talk through that connection, type /msg =nick whatever (note the = sign). In mIRC, you can also start a DCC chat session by selecting _DCC and then Chat from the menu and then entering the nick of the user with whom you wish to chat. A window opens for that dcc chat session.

9. A word of warning

IRC scripts are sets of commands that your client will run. Many otherwise good scripts have been hacked so that if you load them, you can seriously compromise your security (someone can get into your account, delete all of your files, read your mail, etc.). There are also evildoers who try to send people viruses and other bad things. Just like in real life, don’t accept anything from a stranger. There have been many incidents of this type, not just a few. Do not ever run a script unless you know what each line does, not even if it is given to you by a friend, as your friend may not have the expertise to detect well-hidden “trojans”.

Automatic DCC get is a very bad idea! Once it is on, you are susceptible to dangers ranging from disconnection from your server to giving someone else control of your computer. Quite a few people have run into serious problems because of the DCC autoget setting.
