| − | ==Introduction==
| + | #REDIRECT [[IRC]] |
| − | | |
| − | IRC stands for ''Internet Relay Chat'' and is one of the primary means of synchronous communication between people working on an open source project. It's a text-based chat system where clients connect to one or more servers, and the servers relay messages between themselves (hence the name). Communication is done in ''channels'' which individual users join, and users are identified by ''nicks'' (nicknames). In addition to human users, various ''services'' and ''bots'' (robots -- programs) are present in many channels.
| |
| − | | |
| − | There are two IRC networks used by the Open Source communities in which Seneca participates:
| |
| − | | |
| − | * The Freenode network is used by Fedora, X.org, OpenOffice.org, and many other open source projects. For information about the Freenode IRC network, see http://freenode.net/. Freenode's IRC servers are accessible at irc://irc.freenode.net
| |
| − | * Moznet is Mozilla's IRC network. For information about Moznet, see http://irc.mozilla.org. Mozilla's IRC server is irc://moznet (irc.mozilla.org).
| |
| − | | |
| − | ==Basic Usage==
| |
| − | | |
| − | ===IRC Client Software===
| |
| − | | |
| − | There are many IRC client programs available. Wikipedia maintains a [http://en.wikipedia.org/wiki/Comparison_of_Internet_Relay_Chat_clients comparison list of IRC clients]. Three good choices include:
| |
| − | | |
| − | * [https://addons.mozilla.org/en-US/firefox/addon/16 Chatzilla] - a Firefox extension
| |
| − | * [http://en.wikipedia.org/wiki/XChat XChat] - a cross-platform (Linux/Mac OSX/Windows) graphical client. XChat is available in Fedora.
| |
| − | * [http://irssi.org/ Irssi] - a text-mode client. When used with the ''screen'' program on a Linux or Mac OSX host, it can be left running constantly and you can disconnect/reconnect to it from multiple locations. Irssi is available in Fedora.
| |
| − | | |
| − | ===Menus vs. Commands===
| |
| − | | |
| − | Most IRC clients let you perform operations using menus/hotkeys or by typing commands. Commands start with a slash ("/") to distinguish them from text that you are typing into the chat session. Since the commands are the same in all IRC clients, it's worthwhile becoming familiar with them.
| |
| − | | |
| − | ===Choosing a nickname===
| |
| − | | |
| − | Probably you want to use something short and in lowercase. Most people use their name or some portion thereof, but you can choose anything. Most IRC clients will choose a default nickname for you, and you can change it using menu options or by entering the command:
| |
| − | | |
| − | /nick ''newname''
| |
| − | | |
| − | It's strongly recommended that you [http://freenode.net/faq.shtml#registering register] your nick so that you won't lose it to someone else and so that no one else can impersonate you (in fact, some channels may require that you register your nick).
| |
| − | | |
| − | === Connecting to an IRC Network ===
| |
| − | | |
| − | To use IRC, you must first connect to a network through one of its servers. Each graphical client has a way of selecting a network from a list, or you can type '''/server ''hostname'' ''' to connect to a specific IRC host (e.g., '''server irc.mozilla.org''' to connect to Moznet or '''server irc.freenode.net''' to connect to Freenode).
| |
| − | | |
| − | ===Channels, joining and leaving===
| |
| − | | |
| − | Channels (similar to the concept of a "chat room") usually start with the # symbol, for example '''#seneca'''. To join a channel select it from your client's channel menu or type:
| |
| − | | |
| − | /join ''#seneca''
| |
| − | | |
| − | Popular Mozilla channels include:
| |
| − | | |
| − | * [irc://irc.mozilla.org/seneca #seneca] - Seneca's home on moznet (best place to start)
| |
| − | * [irc://irc.mozilla.org/firefox #firefox] - For user and some developer help with Firefox or Thunderbird

| |
| − | | |
| − | You can also start your own channel by joining a new channel name. This can be useful for times when you want to chat with a few specific people at once. For example:
| |
| − | | |
| − | /join meeting123
| |
| − | | |
| − | Channels exist as long as there is someone in them. They disappear when everyone leaves (NOTE: there are ways to change this behaviour, but this is the default).
| |
| − | | |
| − | '''NOTE:''' Due to IRC spam and spambots, many channels require that you are a registered user (i.e., that your nick has been registered) before you can join and/or speak. You can find instructions for registering your nick [http://freenode.net/faq.shtml#registering here].
| |
| − | | |
| − | ===Entering text===
| |
| − | | |
| − | Anything that doesn't begin with a / is regular text that will be broadcast to everyone in the channel, including you.
| |
| − | | |
| − | The reverse is also true: anything beginning with a / is interpreted as an IRC command. You'll learn many of these as you go.
| |
| − | | |
| − | ==Channel Culture==
| |
| − | | |
| − | It is normal to join a channel and say nothing. In fact, it is expected. Don't join a channel and say "hi" or leave and say "bye" -- you may be interrupting a conversation already underway.
| |
| − | | |
| − | It is normal for someone new to join a public channel (i.e., one you can see via /list or IRC > Join Channel) uninvited. Feel free to join as many channels as you like, once you're comfortable with IRC.
| |
| − | | |
| − | It is normal to join a channel and sit there idle for a long time. You might never say anything. This is a good way for you to learn about who is in the channel, what they are talking about, etc. Listening is often more important than talking, because you learn more.
| |
| − | | |
| − | If you have a question you should just ask it rather than saying, "Can I ask a question about ..." or "Does anyone know about ..."
| |
| − | | |
| − | You don't need to direct general questions to a specific person. Rather, you should ask in the channel in general. Someone will usually answer you:
| |
| − | | |
| − | <don> How do I ask a question?
| |
| − | <funny_guy> don: you just did!
| |
| − | | |
| − | If there are several conversations taking place at the same time, it's customary to put the nick of the user you are directing your comment to at the start of the line (as shown in the second line above). Most IRC clients will auto-complete the nick when you press the <tab> key, so you could type "fun<tab>" to fill in the nick "funny_guy".
| |
| − | | |
| − | Channels generally have a purpose, and people are often joined to many different channels at once. You'll see many of the same people in different channels. However, what might be appropriate in one channel often isn't in another. When you enter a channel, take a look at its Topic (displayed at the top, or with the /topic command) for clues.
| |
| − | | |
| − | Generally you should avoid small-talk unless you are sure that it is appropriate. Even if you see others in the channel doing it, don't take that to mean that you should (i.e., channel veterans can get away with things newcomers can't!). At the same time, be ready for a playful and (at times) very sarcastic environment.
| |
| − | | |
| − | Also be aware that you never know who you are talking to based on their nicks (you will learn who people are later, as you get to know people's nicks). Don't make assumptions about people (for example, many of the people in #seneca are students, and an equal number are core Mozilla developers).
| |
| − | | |
| − | == The people in channels ==
| |
| − | | |
| − | Channels have operators, or ops. These are people who have special administrative powers to kick people out or otherwise run IRC server commands. You can often spot them in your client (for example, in ChatZilla and XChat they will appear with a Green Circle, and in irssi they will have an @ symbol before their nick).
| |
| − | | |
| − | You can find-out more about a particular person by using the /whois command, for example:
| |
| − | | |
| − | /whois don
| |
| − | | |
| − | In ChatZilla, try right-clicking a user, then User Commands > Who is; in XChat, right-click on a user and then hover over their nick.
| |
| − | | |
| − | Many people will appear to be in the channel, but not all of them will actually be watching IRC at that moment. It is normal for people to leave their IRC clients connected forever and never leave. This way they can catch-up on conversations they missed while they were away.
| |
| − | | |
| − | Because of this, people will often check to see if someone is really there before talking to them. By convention, people will use the person's nick and "ping" or "ping?" instead of saying, "are you there?":
| |
| − | | |
| − | <don> funny_guy: ping
| |
| − | <funny_guy> don: pong
| |
| − | ...
| |
| − | <don> rob: ping?
| |
| − | <rob> hey don
| |
| − | ...
| |
| − | <don> jim: ping
| |
| − | <jim> pong
| |
| − | | |
| − | The person will often respond with '''"pong."''' People preface text like ping/pong with a person's nick so that their client will alert them to it (often with a beep or pop-up message). This is helpful when there are a lot of people talking at once in a channel. (NOTE: ChatZilla automatically remembers all text that was directed to your nick so you can scan it later. You can see it in the '''moznet''' tab).
| |
| − | | |
| − | It is normal to join conversations in the middle without being invited (within reason and assuming you know the people talking ).
| |
| − | | |
| − | Often you'll want to say something to a particular person and not the whole channel. This is known alternatively as 'msg' (short for message or messaging), private message or private chat, query, etc. There are a number of ways to do this, the simplest being to use the /query or /msg command:
| |
| − | | |
| − | /query don
| |
| − | <opens a private chat/channel with user don>
| |
| − | | |
| − | Most graphical clients let you open a private chat by right-clicking on a user name.

| − | == Tools for collaboration ==
| |
| − | | |
| − | === Using a Pastebin ===
| |
| − | | |
| − | The best way to share long sections of text with other IRC users is '''not''' to paste it into the channel. For any text longer than a few lines (9 being the maximum), for example build output, source code, error messages, configuration text files, etc., you should avoid pasting it into an IRC channel directly. Instead, you should use an on-line "pastebin". These are websites that allow users to temporarily host large quantities of text, and assign them unique URLs. There are a number of pastebins available with similar features (they really differ only in syntax highlighting and retention time):
| |
| − | | |
| − | * The original pastebins: http://pastebin.org http://pastebin.com
| |
| − | * Canadian pastebin: http://pastebin.ca
| |
| − | * Mozilla pastebin: http://mozilla.pastebin.org
| |
| − | * Fedora pastebin: http://fpaste.com
| |
| − | | |
| − | You use simply paste your text into the textbox, and optionally select any syntax highlighting you desire. Finally, add your Name and click the Send button. You'll be taken to a new page. Copy the URL from the address bar, which will look something like this:
| |
| − | | |
| − | http://pastebin.mozilla.org/4248
| |
| − | | |
| − | Now, you can easily share this URL in IRC without actually copying your text directly into the channel. The length of time that the pastebin data will be stored varies between the pastebin sites. '''Note:''' pastebin data is not in any way secure or private! -- don't pastebin confidential information.
| |
| − | | |
| − | === Using private channels with small groups ===
| |
| − | | |
| − | To hold a private discussion with more than one person, you could ask two or three people to join you in a channel name of your choosing:
| |
| − | | |
| − | /join #temp1234
| |
| − | ...invite others to come and see by sending them a /msg or:
| |
| − | /invite ''nick''
| |
| − | ...have the private discussion...
| |
| − | /leave
| |
| − | | |
| − | === Sharing long complicated URLs ===
| |
| − | | |
| − | Many of the URLs that users share with one another on IRC are long or complicated. Because some users work with command-line clients, it can be difficult to copy-and-paste these URLs into the browser. A better solution is to use [http://tinyurl.com TinyURL.com]. TinyURL allows users to paste and submit long URLs in order to generate a much shorter URL. A typical TinyURL, for example the location of Seneca on Google Maps, looks like this:
| |
| − | | |
| − | http://maps.google.com/maps?f=q&hl=en&q=seneca+college&sll=37.0625,-95.677068&sspn=57.424512,108.28125&ie=UTF8&z=12&ll=43.814463,-79.381027&spn=0.103554,0.211487&om=1&iwloc=B
| |
| − | | |
| − | becomes...
| |
| − | | |
| − | http://tinyurl.com/32pcyt
| |
| − | | |
| − | TinyURL now includes the ability for you to specify the last part of the URL, so you can make easy-to-remember short URLs:
| |
| − | | |
| − | http://tinyurl.com/seneca-at-york
| |
| − | | |
| − | TinyURLs never expire, so passing them around in emails, newsgroup postings, etc. won't cause problems.
