Third revision.
This document aims to describe the basics of IRC and respective applications for Linux.
Introduction
This document is still WIP, and should be treated as such. I'll do my best to keep it updated and accurate.
The following bibles shouldn't be ignored:
RFC1459 by Jarkko Oikarinen and Darren Reed was the first about the Internet Relay Chat Protocol. It can be found at
http://ftp.isi.edu/in-notes/rfc1459.txt.
RFC2811 by Christophe Kalt updates RFC1459 and describes the Channel Management of the Internet Relay Chat. It can be found at
http://ftp.isi.edu/in-notes/rfc2811.txt.
RFC2812 by Christophe Kalt updates RFC1459 and describes the Client Protocol of the Internet Relay Chat. It can be found at
http://ftp.isi.edu/in-notes/rfc2812.txt.
RFC2813 by Christophe Kalt updates RFC1459 and describes the Server Protocol of the Internet Relay Chat. It can be found at
http://ftp.isi.edu/in-notes/rfc2813.txt.

Objectives
Among others, the objectives of this mini-HOWTO are:
Link important resources about IRC;
Avoid common misuses of IRC by writing an IRC Etiquette;
List popular clients, servers, bots, and bouncers, along with their maintainers, #channel, small description, download
location, homepage, and hints;
List IRC tools available in the latest release of all major distributions.
Miscellaneous
The latest version of this document is available at
http://www.pervalidus.net/docs/IRC-mini-HOWTO/.
A WIP of the next draft may be available at
http://www.pervalidus.net/docs/IRC-mini-HOWTO/WIP/.
All drafts are archived at
http://www.pervalidus.net/docs/IRC-mini-HOWTO/old/.
You can e-mail me (in English, French, or Portuguese) with suggestions about the mini-HOWTO. I know this is far from
finished, but hope you find it useful. Just don't ask me to add your application or site. Most likely I won't. Also don't ask
for technical support. I have no time to help everyone.
BTW, someone to work on the protocol and server sides would be very welcome to join the project.

Proposed translations will be linked here. Although I can write in Brazilian Portuguese and French, I'm not going to
translate this document in the near future, so feel free to make them.
About IRC
Excerpt from RFC2810:
The IRC (Internet Relay Chat) protocol is for use with text based conferencing. It has been developed since 1989 when it
was originally implemented as a mean for users on a BBS to chat amongst themselves.
First formally documented in May 1993 by RFC 1459 [IRC], the protocol has kept evolving.
The IRC Protocol is based on the client-server model, and is well suited to running on many machines in a distributed
fashion. A typical setup involves a single process (the server) forming a central point for clients (or other servers) to
connect to, performing the required message delivery/multiplexing and other functions. This distributed model,
which requires each server to have a copy of the global state information, is still the most flagrant problem of the protocol
as it is a serious handicap, which limits the maximum size a network can reach. If the existing networks have been able keep
growing at an incredible pace, we must thank hardware manufacturers for giving us ever more powerful systems.
Beginner's guide on using IRC
The standard IRC client is the original ircII client. It's part of most Linux distributions.
Running the ircII program
It's easy to use ircII. Let's say you want to connect to irc.openprojects.net as mini-HOWTO.
At the command line, type:
$ irc mini-HOWTO irc.openprojects.net
You can also export variables, so you won't need to use them at the command line:
$ export IRCNICK=mini-HOWTO IRCSERVER=irc.openprojects.net
Add them to your shell profile (e.g. ~/.bash_profile or ~/.zprofile) when you're done.
Other common variables are IRCNAME and IRCUSER, to respectively set the ircname part of a /whois and username as seen at
the first line 'mini-HOWTO is ~username@hostname (ircname)'. Keep in mind that IRCUSER won't work if you run an ident daemon
(default on most distributions). If you still need to change your username (not recommended, and I hope you're not using IRC
logged as root !), install oidentd from http://ojnk.sourceforge.net/, create
/etc/identd.spoof with a list of users allowed to spoof their ident, and ~/.ispoof with their reply (e.g. reply). Finally run
'/usr/local/sbin/oidentd -g nobody -N -s -u nobody'. Add this to your startup scripts (e.g. /etc/rc.d/rc.local) when you're
done. If not set, IRCNICK, IRCUSER, and IRCNAME will be retrieved from /etc/passwd .
Commands
Use /help to get a list on all available commands (/help help is a good start). Replace nick by any
IRCNICK.
First, /set NOVICE off
/nick IRC-mini-HOWTO changes your IRCNICK to IRC-mini-HOWTO
/set realname The Linux IRC mini-HOWTO changes your IRCNAME to The Linux IRC mini-HOWTO (doesn't change
on the same connection)
/j #LinPeople joins channel #LinPeople
/j #Slackware joins channel #Slackware
/j #LinPeople changes the active current channel to #LinPeople
/msg nick Hi. sends a private message to nick containing Hi.
/notice nick (or #LinPeople) Hi. sends a notice to nick (or #LinPeople) containing Hi.
/query nick starts a private conversation with nick. /query ends the private conversation
/me loves Linux. sends an action to the current channel or query containing IRC-mini-HOWTO loves Linux.
/dcc chat nick starts a chat with nick. Use /msg =nick (notice the =) to send messages over the chat
/dcc send nick /etc/HOSTNAME sends the given file to nick
/dcc get nick receives the file offered by nick
/part leaves the active current channel
/part #Slackware leaves channel #Slackware
/discon disconnects from current IRCSERVER
/server irc.dal.net connects to IRCSERVER irc.dal.net
/quit Bye. quits your IRC session with a reason Bye.
IRC Etiquette
WARNING WARNING WARNING WARNING WARNING
Never use IRC logged as root or any user with excessive privileges. Bad things may happen sooner or later. You were warned.
It's safe if you create 2 users, one of them to only use IRC.
$ man adduser
On Linux channels you shouldn't:
Act as an idiot. If you want to be respected, then first respect each other.
Use colors (^C). Most Linux users don't tolerate such mIRC crazes, and ircII doesn't really support them. The same should
apply for ANSI.
Use full CAPS, bold (^B), reverse (^V), underline (^_), blink (^F), and bell (^G). The first 4 are here to emphasize words,
not the whole text. The last 2 are just very annoying.
Ask if you can ask a question. Just ask, but first read all documentation available on the subject. Start looking at /usr/doc/ , otherwise go to http://www.linuxdoc.org/ or http://www.ibiblio.org/pub/Linux/docs/. And don't repeat your question
immediately. Wait at least 10 minutes. If you don't get any answer it's because nobody knows or wants to help. Respect their
choice, they're not your personal assistant. Also never send mass private messages. It's like SPAM.
Console IRC Clients
ircII
Maintainer: ircII project (ircii @ eterna.com.au)
IRC Channel: #ircII (official channel ?) on EFNet
Originally written by Michael Sandrof, ircII comes with most Linux distributions. It uses termcap and shouldn't be a
choice for most users, but is a standard. Mathusalem and other gurus will use it. Less ventured will regret to have it
installed.
You can get the latest version of ircII from ftp://ircftp.au.eterna.com.au/pub/ircII/.
Homepage at http://www.eterna.com.au/ircii/.
EPIC
Maintainer: EPIC Software Labs (ircii-epic @ concentric.net)
IRC Channel: #EPIC on EFNet
Based on ircII, EPIC (Enhanced Programmable ircII Client) is meant for real scripters and users searching freedom. When
you start it for the first time you'll notice that you should really learn the basics of scripting.
You can get the latest version of EPIC from ftp://ftp.epicsol.org/pub/epic/.
Homepage at http://www.epicsol.org/.
BitchX
Maintainer: Colten Edwards (edwards @ bitchx.dimension6.com)
IRC Channel: #BitchX on EFNet
Based on ircII and EPIC, BitchX could be compared to the Pine MUA. Bloatware (doesn't mean you shouldn't use it) and
widely used. The choice for users that want a client with built-in facilities. It can be built with the GNOME libraries by
using the configure option --with-gtk. Don't be surprised if all you get is a XTerm-BitchX instead.
You can get the latest version of BitchX from ftp://ftp.bitchx.com/pub/BitchX/source/.

irssi
Maintainer: Timo Sirainen (tss @ iki.fi)
IRC Channel: #irssi on OPN and IRCnet
Timo released yagIRC ~3 years ago. It was a GUI client using the GTK+ toolkit. The army called on him, and the new
maintainers wouldn't do the job. yagIRC passed away and he started irssi as a replacement. It used GTK+. GNOME and curses
versions would appear later. As of 0.7.90 it's only a modular text mode client. Supports Perl scripting.

Installation
Clients
All popular clients use GNU autoconf and GNU automake, thus come with a
configure script. Read the installation instructions after you unpack the sources. Be sure you have the required libraries in
order to build. Doing cd sources;mkdir objdir;cd objdir; ../configure --help;../configure
your_options_here;make;make install (or make install_strip) > ~/sources_install.log is the right
procedure. Also note that for ircII, EPIC, and BitchX you should really edit include/config.h to suit your
needs.
Servers
Do you really need help to set up a server ?
~$ vim ircd.conf
But what's already included in my distribution ? (Linux on x86)

Khaled Mardam-Bey must be stopped :)
'If idiots could fly, IRC would be an airport'. I don't know who wrote that, but it makes sense. For those of you using IRC to
annoy and piss off I ordered a /kill for Christmas.
