- Chapter 11: IRC, MUDs AND OTHER THINGS THAT ARE MORE FUN THAN THEY SOUND
-
-
-
-
- Many Net systems provide access to a series of interactive
- services that let you hold live "chats" or play online games with
- people around the world. To find out if your host system offers
- these, you can ask your system administrator or just try them -- if
- nothing happens, then your system does not provide them. In general,
- if you can use telnet and ftp, chances are good you can use these
- services as well.
-
-
- 11.1 TALK
-
-
- This is the Net equivalent of a telephone conversation and
- requires that both you and the person you want to talk to have access
- to this function and are online at the same time. To use it, type
-
- talk user@site.name
-
- where that is the e-mail address of the other person. She will see
- something like this on her screen:
-
- talk: connection requested by yourname@site.name
- talk: respond with: talk yourname@site.name
-
- To start the conversation, she should then type (at her host system's
- command line):
-
- talk yourname@site.name
-
- where that is your e-mail address. Both of you will then get a top
- and bottom window on your screen. She will see everything you type in
- one window; you'll see everything she types in the other. To
- disconnect, hit control-C.
- One note: Public-access sites that use Sun computers sometimes have
- trouble with the talk program. If talk does not work, try typing
-
- otalk
-
- or
-
- ntalk
-
- instead. However, the party at the other end will have to have the same
- program online for the connection to work.
-
-
- 11.2 INTERNET RELAY CHAT
-
-
- IRC is a program that lets you hold live keyboard conversations
- with people around the world. It's a lot like an international CB
- radio - it even uses "channels." Type something on your computer and
- it's instantly echoed around the world to whoever happens to be on the
- same channel with you. You can join in existing public group chats or
- set up your own. You can even create a private channel for yourself
- and as few as one or two other people. And just like on a CB radio,
- you can give yourself a unique "handle" or nickname.
- IRC currently links host systems in 20 different countries, from
- Australia to Hong Kong to Israel.
- Unfortunately, it's like telnet -- either your site has it or it
- doesn't. If your host system does have it, Just type
-
- irc
-
- and hit enter. You'll get something like this:
-
-
- *** Connecting to port 6667 of server world.std.com
- *** Welcome to the Internet Relay Network, adamg
- *** Your host is world.std.com, running version 2.7.1e+4
- *** You have new mail.
- *** If you have not already done so, please read the new user information with
- +/HELP NEWUSER
- *** This server was created Sat Apr 18 1992 at 16:27:02 EDT
- *** There are 364 users on 140 servers
- *** 45 users have connection to the twilight zone
- *** There are 124 channels.
- *** I have 1 clients and 3 servers
- MOTD - world.std.com Message of the Day -
- MOTD - Be careful out there...
- MOTD -
- MOTD - ->Spike
- * End of /MOTD command.
-
-
-
-
-
-
- 23:13 [1] adamg [Mail: 32] * type /help for help
-
- ----------------------------------------------------------------------
-
-
-
-
- You are now in channel 0, the "null" channel, in which you can look
- up various help files, but not much else. As you can see, IRC takes over
- your entire screen. The top of the screen is where messages will
- appear. The last line is where you type IRC commands and messages. All
- IRC commands begin with a /. The slash tells the computer you are about
- to enter a command, rather than a message. To see what channels are
- available, type
-
- /list
-
- and hit enter. You'll get something like this:
-
-
- *** Channel Users Topic
- *** #Money 1 School CA$H (/msg SOS_AID help)
- *** #Gone 1 ----->> Gone with the wind!!! ------>>>>>
- *** #mee 1
- *** #eclipse 1
- *** #hiya 2
- *** #saigon 4
- *** #screwed 3
- *** #z 2
- *** #comix 1 LET'S TALK 'BOUT COMIX!!!!!
- *** #Drama 1
- *** #RayTrace 1 Rendering to Reality and Back
- *** #NeXT 1
- *** #wicca 4 Mr. Potato Head, R. I. P.
- *** #dde^mhe` 1 no'ng chay? mo*? ...ba` con o*iiii
- *** #jgm 1
- *** #ucd 1
- *** #Maine 2
- *** #Snuffland 1
- *** #p/g! 4
- *** #DragonSrv 1
-
- Because IRC allows for a large number of channels, the list might
- scroll off your screen, so you might want to turn on your computer's
- screen capture to capture the entire list. Note that the channels
- always have names, instead of numbers. Each line in the listing tells
- you the channel name, the number of people currently in it, and whether
- there's a specific topic for it. To switch to a particular channel,
- type
-
- /join #channel
-
- where "#channel" is the channel name and hit enter. Some "public"
- channels actually require an invitation from somebody already on it. To
- request an invitation, type
-
- /who #channel-name
-
- where channel-name is the name of the channel, and hit enter. Then ask
- someone with an @ next to their name if you can join in. Note that
- whenever you enter a channel, you have to include the #. Choose one
- with a number of users, so you can see IRC in action.
- If it's a busy channel, as soon as you join it, the top of your
- screen will quickly be filled with messages. Each will start with a
- person's IRC nickname, followed by his message.
- It may seem awfully confusing at first. There could be two or
- three conversations going on at the same time and sometimes the
- messages will come in so fast you'll wonder how you can read them all.
- Eventually, though, you'll get into the rhythm of the channel and
- things will begin to make more sense. You might even want to add your
- two cents (in fact, don't be surprised if a message to you shows up on
- your screen right away; on some channels, newcomers are welcomed
- immediately). To enter a public message, simply type it on that bottom
- line (the computer knows it's a message because you haven't started the
- line with a slash) and hit enter.
- Public messages have a user's nickname in brackets, like this:
-
- <tomg>
-
- If you receive a private message from somebody, his name will be
- between asterisks, like this:
-
- *tomg*
-
-
- 11.3 IRC COMMANDS
-
-
- Note: Hit enter after each command.
-
-
- /away When you're called away to put out a grease fire
- in the kitchen, issue this command to let others know
- you're still connected but just away from your terminal
- or computer for awhile.
-
-
- /help Brings up a list of commands for which there is a help
- file. You will get a "topic:" prompt. Type in the
- subject for which you want information and hit enter.
- Hit enter by itself to exit help.
-
- /invite Asks another IRC to join you in a conversation.
-
- /invite fleepo #hottub
-
- would send a message to fleepo asking him to join you on
- the #hottub channel. The channel name is optional.
-
-
-
- /join Use this to switch to or create a particular channel,
- like this:
-
- /join #hottub
-
- If one of these channels exists and is not a private
- one, you will enter it. Otherwise, you have just
- created it. Note you have to use a # as the first
- character.
-
-
- /list This will give you a list of all available public
- channels, their topics (if any) and the number of users
- currently on them. Hidden and private channels are not
- shown.
-
- /m name Send a private message to that user.
-
- /mode This lets you determine who can join a channel you've
- created.
-
- /mode #channel +s
-
- creates a secret channel.
-
-
- /mode #channel +p
-
- makes the channel private
-
- /nick This lets you change the name by which others see you.
-
- /nick fleepo
-
- would change your name for the present session to
- fleepo. People can still use /whois to find your e-mail
- address. If you try to enter a channel where somebody
- else is already using that nickname, IRC will ask you to
- select another name.
-
- /query This sets up a private conversation between you and
- another IRC user. To do this, type
-
- /query nickname
-
- Every message you type after that will go only to that
- person. If she then types
-
- /query nickname
-
- where nickname is yours, then you have established a
- private conversation. To exit this mode, type
-
- /query
-
- by itself. While in query mode, you and the other
- person can continue to "listen" to the discussion on
- whatever public channels you were on, although neither
- of you will be able to respond to any of the messages
- there.
-
- /quit Exit IRC.
-
- /signoff Exit IRC.
-
- /summon Asks somebody connected to a host system with IRC to
- join you on IRC. You must use the person's entire e-mail
- address.
-
- /summon fleepo@foo.bar.com
-
- would send a message to fleepo asking him to start IRC.
- Usually not a good idea to just summon people unless you
- know they're already amenable to the idea; otherwise you
- may wind up annoying them no end. This command does not
- work on all sites.
-
- /topic When you've started a new channel, use this command to let
- others know what it's about.
-
- /topic #Amiga
-
- would tell people who use /list that your channel is meant
- for discussing Amiga computers.
-
- /who <chan> Shows you the e-mail address of people on a particular
- channel.
-
- /who #foo
-
- would show you the addresses of everybody on channel foo.
-
- /who
-
- by itself shows you every e-mail address for every person
- on IRC at the time, although be careful: on a busy night
- you might get a list of 500 names!
-
- /whois Use this to get some information about a specific IRC
- user or to see who is online.
-
- /whois nickname
-
- will give you the e-mail address for the person using
- that nickname.
-
- /whois *
-
- will list everybody on every channel.
-
- /whowas Similar to /whois; gives information for people who
- recently signed off IRC.
-
-
- 11.4 IRC IN TIME OF CRISIS
-
-
- IRC has become a new medium for staying on top of really big
- breaking news. In 1993, when Russian lawmakers barricaded themselves
- inside the parliament building, some enterprising Muscovites and a couple
- of Americans set up a "news channel" on IRC to relay first-person
- accounts direct from Moscow. The channel was set up to provide a
- continuous loop of information, much like all-news radio stations that
- cycle through the day's news every 20 minutes. In 1994, Los Angeles
- residents set up a similar channel to relay information related to the
- Northridge earthquake. In both cases, logs of the channels were archived
- somewhere on the Net, for those unable to "tune in" live.
- How would you find such channels in the future? Use the /list
- command to scroll through the available channels. If one has been set up
- to discuss a particular breaking event, chances are you'll see a brief
- description next to the channel name that will tell you that's the place
- to tune.
-
-
- 11.5 MUDs
-
-
- Multiple-User Dimensions or Dungeons (MUDs) take IRC into the
- realm of fantasy. MUDs are live, role-playing games in which you
- enter assume a new identity and enter an alternate reality through
- your keyboard. As you explore this other world, through a series of
- simple commands (such as "look," "go" and "take"), you'll run across
- other users, who may engage you in a friendly discussion, enlist your
- aid in some quest or try to kill you for no apparent reason.
- Each MUD has its own personality and creator (or God) who was
- willing to put in the long hours required to establish the particular
- MUD's rules, laws of nature and information databases. Some MUDs
- stress the social aspects of online communications -- users frequently
- gather online to chat and join together to build new structures or
- even entire realms. Others are closer to "Dungeons and Dragons" and
- are filled with sorcerers, dragons and evil people out to keep you
- from completing your quest -- through murder if necessary.
- Many MUDs (there are also related games known as MUCKs and MUSEs)
- require you to apply in advance, through e-mail, for a character name
- and password. One that lets you look around first, though, is
- HoloMuck at McGill University in Montreal. The premise of this game
- is that you arrive in the middle of Tanstaafl, a city on the planet
- Holo. You have to find a place to live (else you get thrown into the
- homeless shelter) and then you can begin exploring. Magic is allowed
- on this world, but only outside the city limits. Get bored with the
- city and you can roam the rest of the world or even take a trip into
- orbit (of course, all this takes money; you can either wait for your
- weekly salary or take a trip to the city casino). Once you become
- familiar with the city and get your own character, you can even begin
- erecting your own building (or subway line, or almost anything else).
- To connect, telnet to
-
- collatz.mcrcim.mcgill.edu 5757
-
- When you connect, type
-
- connect guest guest
-
- and hit enter. This connects you to the "guest" account, which
- has a password of "guest."
- You'll see this:
-
- The Homeless Shelter(#22Rna)
- You wake up in the town's Homeless Shelter, where vagrants are put for
- protective holding. Please don't sleep in public places-- there are plenty of
- open apartments available. Type 'apartments' to see how to get to an
- apartment building with open vacancies.
- There is a small sign on the wall here, with helpful information. Type 'look
- sign' to read it.
- The door is standing open for your return to respectable society. Simply walk
- 'out' to the center.
- Of course, you want to join respectable society, but first you
- want to see what that sign says. So you type
-
- look sign
-
- and hit enter, which brings up a list of some basic commands. Then
- you type
-
- out
-
- followed by enter, which brings up this:
-
- You slip out the door, and head southeast...
- Tanstaafl Center
- This is the center of the beautiful town of Tanstaafl. High Street runs north
- and south into residential areas, while Main Street runs east and west into
- business districts.
- SW: is Tanstaafl Towers. Please claim an apartment... no sleeping in public!
- SE: the Public Library offers both information and entertainment.
- NW: is the Homeless Shelter, formerly the Town Jail.
- NE: is Town Hall, site of several important services, including: Public
- Message Board, Bureau of Land Management (with maps and regulations), and
- other governmental/ bureaucratic help.
- Down: Below a sign marked with both red and blue large letter 'U's, a
- staircase leads into an underground subway passage.
- (Feel free to 'look' in any direction for more information.)
- [Obvious exits: launch, d, nw, se, w, e, n, s, ne, sw]
- Contents:
- Instructions for newcomers
- Directional signpost
- Founders' statue
-
- To see "Instructions for newcomers", type
-
- look Instructions for newcomers
-
- and hit enter. You could do the same for "Directional signpost" and
- "Founders' statue." Then type
-
- SW
-
- and enter to get to Tanstaafl Towers, the city housing complex, where
- you have to claim an apartment (you may have to look around; many will
- already) be occupied. And now it's off to explore Holo! One command
- you'll want to keep in mind is "take." Periodically, you'll come
- across items that, when you take them will confer certain abilities or
- powers on you. If you type
-
- help
-
- and enter, you'll get a list of files you can read to learn more about
- the MUD's commands.
- The "say" command lets you talk to other players publicly. For
- example,
-
- say Hey, I'm here!
-
- would be broadcast to everybody else in the room with you. If you
- want to talk to just one particular person, use "whisper" instead of
- "say."
-
- whisper agora=Hey, I'm here!
-
- would be heard only by agora. Another way to communicate with
- somebody regardless of where on the world they are is through your
- pager. If you suddenly see yours go off while visiting, chances are
- it's a wizard checking to see if you need any help. To read his
- message, type
-
- page
-
- To send him a message, type
-
- page name=message
-
- where name is the wizard's name (it'll be in the original message).
- Other MUDs and MUCKs may have different commands, but generally
- use the same basic idea of letting you navigate through relatively
- simple English commands.
- When you connect to a MUD, choose your password as carefully as
- you would one for your host system; alas, there are MUD crackers who
- enjoy trying to break into other people's MUD accounts. And never,
- never use the same password as the one you use on your host system!
- MUDs can prove highly addicting. "The jury is still out on
- whether MUDding is 'just a game' or 'an extension of real life with
- gamelike qualities'," says Jennifer Smith, an active MUD player who
- wrote an FAQ on the subject.
- She adds one caution: "You shouldn't do anything that you
- wouldn't do in real life, even if the world is a fantasy world. The
- important thing to remember is that it's the fantasy world of possibly
- hundreds of people, and not just yours in particular. There's a
- human being on the other side of each and every wire! Always remember
- that you may meet these other people some day, and they may break
- your nose. People who treat others badly gradually build up bad
- reputations and eventually receive the NO FUN Stamp of Disapproval."
-
-
-
- 11.6 GO, GO, GO (AND CHESS, TOO)!
-
- Fancy a good game of go or chess? You no longer have to head for
- the nearest park with a board in hand. The Internet has a couple of
- machines that let you engage people from around the world in your
- favorite board games. Or, if you prefer, you can watch matches in
- progress.
- To play go,
-
- telnet hellspark.wharton.upenn.edu 6969
- log on as: guest
-
- You'll find prompts to various online help files to get you started.
- For a chess match,
-
- telnet news.panix.com 5000
- log on as: guest
-
- You'll find prompts for online help files on the system, which lets you
- choose your skill level.
-
-
- 11.7 THE OTHER SIDE OF THE COIN
-
-
- All is not fun and games on the Net. Like any community, the Net
- has its share of obnoxious characters who seem to exist only to make
- your life miserable (you've already met some of them in the chapter on
- Usenet). There are people who seem to spend a bit more time on
- the Net than many would find healthy. It also has its criminals.
- Clifford Stoll writes in "The Cuckoo's Egg" how he tracked a team of
- German hackers who were breaking into U.S. computers and selling the
- information they found to the Soviets. Robert Morris, a Cornell
- University student, was convicted of unleashing a "worm" program that
- effectively disabled several thousand computers connected to the
- Internet.
- Of more immediate concern to the average Net user are crackers
- who seek to find other's passwords to break into Net systems and people
- who infect programs on ftp sites with viruses.
- There is a widely available program known as "Crack" that can
- decipher user passwords composed of words that might be found in a
- dictionary (this is why you shouldn't use such passwords). Short of
- that, there are the annoying types who, as mentioned above, take a
- special thrill in trying to make you miserable. The best advice in
- dealing with them is to count to 10 and then ignore them -- like
- juveniles everywhere, most of their fun comes in seeing how upset you
- can get.
- Meanwhile, two Cornell University students pled guilty in 1992 to
- uploading virus-infected Macintosh programs to ftp sites. If you plan
- to try out large amounts of software from ftp sites, it might be wise to
- download or buy a good anti-viral program.
- But can law enforcement go too far in seeking out the criminals?
- The Electronic Frontier Foundation was founded in large part in
- response to a series of government raids against an alleged gang of
- hackers. The raids resulted in the near bankruptcy of one game
- company never alleged to have had anything to do with the hackers,
- when the government seized its computers and refused to give them
- back. The case against another alleged participant collapsed in court
- when his attorney showed the "proprietary" and supposedly hacked
- information he printed in an electronic newsletter was actually
- available via an 800 number for about $13 -- from the phone company
- from which that data was taken.
-
-
- 11.8 FYI
-
- You can find discussions about IRC in the alt.irc newsgroup.
- "A Discussion on Computer Network Conferencing," by Darren Reed
- (May, 1992), provides a theoretical background on why conferencing
- systems such as IRC are a Good Thing. It's available through ftp at
- nic.ddn.mil in the rfc directory as rfc1324.txt.
- Every Friday, Scott Goehring posts a new list of MUDs and related
- games and their telnet addresses in the newsgroup rec.games.mud.announce.
- There are several other mud newsgroups related to specific types of MUDs,
- including rec.games.mud.social, rec.games.mud.adventure,
- rec.games.mud.tiny, rec.games.mud.diku and rec.games.mud.lp.
- For a good overview of the impact on the Internet of the Morris
- Worm, read "Virus Highlights Need for Improved Internet Management," by
- the U.S. General Accounting Office (June, 1989). You can get a copy via
- ftp from cert.sei.cmu.edu in the pub/virus-l/docs directory. It's
- listed as gao_rpt.
- Clifford Stoll describes how the Internet works and how he tracked
- a group of KGB-paid German hackers through it, in "The Cuckoo's Egg:
- Tracking a Spy through the Maze of Computer Espionage," Doubleday
- (1989).
