Internet Relay Chat (IRC)

Overview

IRC (Internet Relay Chat) this is a form of real-time Internet text messaging or chat. The most abundant use of this is for communication among groups and group members in discussion forums (channels). Another feature that IRC has is one on one communication for private messages only viewable between the speakers. There is also Direct Client to Client speaking available for use. The final advantage of using IRC is availability it is virtually supported by every computer operating system that supports TCP/IP networking.

Technical Information

IRC is an open protocol that uses TCP. An IRC server is able to connect to other IRC servers to expand the IRC network. Users access IRC networks by connecting a client to a server. There are many clients such as mIRC and EFnet Some IRC servers do not require people to register an account but will ask you to set a nickname before connecting. Although our class IRC (lab46) requires a lab46 username. The standard structure of a network of IRC servers is a tree. Messages are sent along only necessary branches of the tree but network state is sent to every server.

IRC Clients

Some popular Internet Relay Chat clients for Unix and Linux include Irssi, XChat, Konversation, Pidgin, Kopete and the venerable ircII. In addition to stand-alone IRC clients, there are also browser-based IRC clients. The Opera browser has an IRC client built into it, and the ChatZilla IRC client is available as an add-on for Mozilla Firefox. It is also possible to use web-based clients like Mibbit and WebIRC.

Here are a few of the IRC clients for Unix and Linux:

To see a more comprehensive listing and comparison of IRC clients and their features, see Wikipedia's Comparison of Internet Relay Chat clients.

IRC BOTS

Since this page is not broken down properly to the appropriate discussion areas, I will use this space to give an overview of IRC Bots in general.

If you are interested in creating your own bot from a skeleton this link is helpful.

Perl IRC Bot Skeleton

This link will give you an overview of the available bots out there to mess with if you don't want to start from scratch.

IRC/Bots - Meta

One last link to get information on what a bot is, along with additional information on how to create bots can be found at this site.

IRC BOTS

More information can be found by searching various sites, and by checking IRC servers for other people interested in programming IRC bots.

IRC Bots

Automated clients are what as known as bots. Bots serve as protection agents and points of contacts for information for all the channels they are connected to. Because of bots superior speeds compared to humans they make the perfect candidate to do this. Bots can be written in a wide variety of languages and also a wide variety of implementations exist. Modern day IRC bots are able to communicate back forth between the user which prompted for their help and they are controlled by the users as well. Then comes to the part where bots can me used for malevolent uses. The bots can take over a channel or flood them, which would oust their owners. If a user can prevent it, try not to let two bots on the system start communicating back and forth between one another. Due to the fact that a bot can respond a lot quicker than a human, so the two bots will talk back and forth at an alarming rate; which is never good.

Phenny Bot

Phenny is the IRC robot used by the UNIC/Linux class to carry out case study #7, Scheduled Tasks. Phenny can be downloaded from http://inamidst.com/phenny/ .
Once Phenny has been downloaded, it can then be e-mailed to a student's lab46 e-mail account. Next, the student can save the attachment to their home directory, for example: /home/username .
Either that or the student can right click on the link they find on the internet and then paste it in their shell prompt after typing “wget”.
Next, the student can unarchive the phenny.tar.bz2 file using the command line:
lab46:~$ tar -xvjf phenny.tar.bz2.
Next, the student, can cat README.txt file (/home/username/phenny), and follow the listed directions the student should also run the phenny script by navigating to the phenny sub-directory “/home/username/phenny” (make sure you are not in the .phenny subdirectory) and runny phenny as follows: lab46:~/phenny$ ./phenny
Once the phenny script has been run, the student should navigate to the .phenny directory (/home/username/.phenny) and change the default.py file.
For example, I changed my default.py file as follows (note that the '#' character is a remark):
#nick = 'phenny'
nick = 'RineBot'
#host = 'irc.example.net'
host = 'irc.offbyone.lan'
#channels = ['#example', '#test']
channels = ['#botchan','#botchan'] (note, the second botchan is not neccesary)
#owner = 'yournickname'
owner = 'jr018429'
Simply change the nick and owner fields to reflect your bot's nickname and your username respectively. Next, change the host and channel fields per the instructions given by the instructor on the case study #7 web page http://lab46.corning-cc.edu/haas/fall2010/unix/cs/cs7 .

Bot Nicknames cannot be longer than 8 characters. Attempting to use longer nicknames will prevent the Bot from running properly. Be certain to replace all double quotes (“”) located in the default script with single quotes (). After editing the default.py file, navigate back to the phenny (and not.phenny-/home/username/phenny) and run the phenny script again. The student should then a screen full of script that ends with the word “connected”. Once the connection is established, the student can open another SSH session and get into the irssi environment. At the UNIX/Linux command line, the student should enter the following:
irssi
The irssi screen should now be displayed. At the [(status)] prompt, enter /server irc .
Next, enter /join botchan .
Begin entering commands…
To test your bot, at the irssi prompt, enter the following: .dict geek .
The student should see something like this:
<nick> .dict geek
<Bot> geek - 1. awkward person, 2. obsessive computer user
To test your bot further, refer to the list of commands below.
Once you verify that your Bot is functioning you can keep it running on the IRC server by opening and executing it in a shell which you can disconnect from. If you would rather keep your number of active shells down you can also use a no hangup command while forcing the Bot to run in the background. This is accomplished by using the command nohup phenny 2> ~/.phenny/log.txt &
Try “phenny: help?”, “phenny: help g”, and “/msg phenny .commands” for help.
==== Commands ==== Here are some commands for the Phenny Bot from [http://inamidst.com/phenny/|inamidst.com]: ^ Command ^ Description ^ |
.beats | Returns the current internet time | | .bytes <str> | Return the byte representation of <str>. | | .char <seq> | Get info about a sequence. | | .u <regexp> | Search for a particular Unicode codepoint. | | .ety <word> | Return a word's etymology. | | .g <query> | Google for <query> and return the top result. | | .calc <query> | Return the Frink calc for <query>. | | .gc <query> | Return the Googlecount for <query>. | | .head <URI> | Perform an HTTP HEAD on URI. | | phenny: “<phrase>”? | Translate <phrase> | | tell <nick> <blargh> | I'll remind nick about blargh. | | .seen <nick> | Reports when <nick> was last seen. | | .t [ <timezone> ] | Returns the current time | | .tock | Return the time from the USNO Master Clock. | | .val <URI> | Validate <URI> using validator.w3.org. | | .dict <word> | Returns the definition of <word>. | | .weather <ICAO> | Show the weather at airport with the code <ICAO>. | | .wik <term>'' | Except information about <term> from Wikipedia. |
Careful with the commands If you use the same one too much, too fast, then you'll get kicked from the channel. Which I thought was kind of funny.

You can make your own modules

Create a text file and give it the extension of .py and save it to the modules section of phenny
A few examples given at https://github.com/myano/jenni/wiki/How-to-create-a-phenny-module
def helloworld(phenny, input):

                  phenny.say("Hello world!")
          helloworld.commands = ['hello']
          helloworld.priority = 'medium'

Create a rule
def interjection(phenny, input):

                  phenny.say(input.nick + '!')
          interjection.rule = r'$nickname!'
          interjection.priority = 'high'
          interjection.thread = False

Or, Event
def message_join(phenny, input):

                  ...
          message_join.event = 'JOIN'
          message_join.rule = r'.*'

File Sharing

The Lab46 IRC server has basic file sharing support. Users are able to transfer files to other users. This can be accomplished by using the “dcc” command in irssi. One user must send a request to send a file and the other user must accept the file before a file transfer will begin. When a user sends a request to another user the recipient will be notified with a message in the chat window. Below are the commands used to send and recieve files.

To send a file in irssi use the following command,

/dcc send "recipient" "file to be sent"

Example, /dcc send wedge /home/user/folder/data.txt

To receive a file in irssi use the following command,

/dcc get

History

Internet Relay Chat (IRC) is a form of real-time Internet text messaging (chat) or synchronous conferencing. It is mainly for group communication in discussion forums, called channels, but also allows one-to-one communication via private message as well as chat transfers via Direct Client-to-Client.

IRC was created by Jarkko Oikarinen in August 1988 to replace a program called MUT (MultiUser Talk) on a BBS called OuluBox in Finland. Oikarinen found inspiration in a chat system known as Bitnet Relay, which operated on the BITNET.

IRC client software is available for nearly every computer operating system that supports TCP/IP networking.
