Big Dummy's Guide to the Internet

1.1 READY, SET ...

The world is just a phone call away. With a computer and modem, you'll be able to connect to the Internet, the world's largest computer network (and if you're lucky, you won't even need the modem; many colleges and companies now give their students or employees direct access to the Internet). The phone line can be your existing voice line - just remember that if you have any extensions, you (and everybody else in the house or office) won't be able to use them for voice calls while you are connected to the Net. A modem is a sort of translator between computers and the phone system. It's needed because computers and the phone system process and transmit data, or information, in two different, and incompatible ways. Computers "talk" digitally; that is, they store and process information as a series of discrete numbers. The phone network relies on analog signals, which on an oscilloscope would look like a series of waves. When your computer is ready to transmit data to another computer over a phone line, your modem converts the computer numbers into these waves (which sound like a lot of screeching) - it "modulates" them. In turn, when information waves come into your modem, it converts them into numbers your computer can process, by "demodulating" them. Increasingly, computers come with modems already installed. If yours didn't, you'll have to decide what speed modem to get. Modem speeds are judged in "bps rate" or bits per second. One bps means the modem can transfer roughly one bit per second; the greater the bps rate, the more quickly a modem can send and receive information. A letter or character is made up of eight bits. You can now buy a 2400-bps modem for well under $60 - and most now come with the ability to handle fax messages as well. At prices that now start around $150, you can buy a modem that can transfer data at 14,400 bps (and often even faster, using special compression techniques). If you think you might be using the Net to transfer large numbers of files, a faster modem is always worth the price. It will dramatically reduce the amount of time your modem or computer is tied up transferring files and, if you are paying for Net access by the hour, will save you quite a bit in online charges. Like the computer to which it attaches, a modem is useless without software to tell it how to work. Most modems today come with easy-to-install software. Try the program out. If you find it difficult to use or understand, consider a trip to the local software store to find a better program. You can spend several hundred dollars on a communications program, but unless you have very specialized needs, this will be a waste of money, as there are a host of excellent programs available for around $100 or less. Among the basic features you want to look for are a choice of different "protocols" (more on them in a bit) for transferring files to and from the Net and the ability to write "script" or "command" files that let you automate such steps as logging into a host system. When you buy a modem and the software, ask the dealer how to install and use them. Try out the software if you can. If the dealer can't help you, find another dealer. You'll not only save yourself a lot of frustration, you'll also have practiced the prime Internet directive: "Ask. People Know." To fully take advantage of the Net, you must spend a few minutes going over the manuals or documentation that comes with your software. There are a few things you should pay special attention to: uploading and downloading; screen capturing (sometimes called "screen dumping"); logging; how to change protocols; and terminal emulation. It is also essential to know how to convert a file created with your word processing program into "ASCII" or "text" format, which will let you share your thoughts with others across the Net. Uploading is the process of sending a file from your computer to a system on the Net. Downloading is retrieving a file from somewhere on the Net to your computer. In general, things in cyberspace go "up" to the Net and come "down" to you. Chances are your software will come with a choice of several "protocols" to use for these transfers. These protocols are systems designed to ensure that line noise or static does not cause errors that could ruin whatever information you are trying to transfer. Essentially, when using a protocol, you are transferring a file in a series of pieces. After each piece is sent or received, your computer and the Net system compare it. If the two pieces don't match exactly, they transfer it again, until they agree that the information they both have is identical. If, after several tries, the information just doesn't make it across, you'll either get an error message or your screen will freeze. In that case, try it again. If, after five tries, you are still stymied, something is wrong with a) the file; b) the telephone line; c) the system you're connected to; or d) your own computer. From time to time, you will likely see messages on the Net that you want to save for later viewing - a recipe, a particularly witty remark, something you want to write your congressman about, whatever. This is where screen capturing and logging come in. When you tell your communications software to capture a screen, it opens a file in your computer (usually in the same directory or folder used by the software) and "dumps" an image of whatever happens to be on your screen at the time. Logging works a bit differently. When you issue a logging command, you tell the software to open a file (again, usually in the same directory or folder as used by the software) and then give it a name. Then, until you turn off the logging command, everything that scrolls on your screen is copied into that file, sort of like recording on videotape. This is useful for capturing long documents that scroll for several pages - using screen capture, you would have to repeat the same command for each new screen. Terminal emulation is a way for your computer to mimic, or emulate, the way other computers put information on the screen and accept commands from a keyboard. In general, most systems on the Net use a system called VT100. Fortunately, almost all communications programs now on the market support this system as well - make sure yours does. You'll also have to know about protocols. There are several different ways for computers to transmit characters. Fortunately, there are only two protocols that you're likely to run across: 8-1-N (which stands for "8 bits, 1 stop bit, no parity" - yikes!) and 7-1-E (7 bits, 1 stop bit, even parity). In general, Unix-based systems use 7-1-E, while MS-DOS-based systems use 8-1-N. What if you don't know what kind of system you're connecting to? Try one of the settings. If you get what looks like gobbledygook when you connect, you may need the other setting. If so, you can either change the setting while connected, and then hit enter, or hang up and try again with the other setting. It's also possible your modem and the modem at the other end can't agree on the right bps rate. If changing the protocols doesn't work, try using another bps rate (but no faster than the one listed for your modem). Don't worry, remember, you can't break anything! If something looks wrong, it probably is wrong. Change your settings and try again. Nothing is learned without trial, error and effort. There are the basics. Now on to the Net!

1.2 GO!

Once, only people who studied or worked at an institution directly tied to the Net could connect to the world. Today, though, an ever-growing number of "public-access" systems provide access for everybody. These systems can now be found in several states, and there are a couple of sites that can provide access across the country. There are two basic kinds of these host systems. The more common one is known as a UUCP site (UUCP being a common way to transfer information among computers using the Unix operating system) and offers access to international electronic mail and conferences. However, recent years have seen the growth of more powerful sites that let you tap into the full power of the Net. These Internet sites not only give you access to electronic mail and conferences but to such services as databases, libraries and huge file and program collections around the world. They are also fast - as soon as you finish writing a message, it gets zapped out to its destination. Some sites are run by for-profit companies; others by non-profit organizations. Some of these public-access, or host, systems, are free of charge. Others charge a monthly or yearly fee for unlimited access. And a few charge by the hour. Systems that charge for access will usually let you sign up online with a credit card. Some also let you set up a billing system. But cost should be only one consideration in choosing a host system, especially if you live in an area with more than one provider. Most systems let you look around before you sign up. What is the range of each of their services? How easy is each to use? What kind of support or help can you get from the system administrators? The last two questions are particularly important because many systems provide no user interface at all; when you connect, you are dumped right into the Unix operating system. If you're already familiar with Unix, or you want to learn how to use it, these systems offer phenomenal power - in addition to Net access, most also let you tap into the power of Unix to do everything from compiling your own programs to playing online games. But if you don't want to have to learn Unix, there are other public-access systems that work through menus (just like the ones in restaurants; you are shown a list of choices and then you make your selection of what you want), or which provide a "user interface" that is easier to figure out than the ever cryptic Unix. If you don't want or need access to the full range of Internet services, a UUCP site makes good financial sense. They tend to charge less than commercial Internet providers, although their messages may not go out as quickly. Some systems also have their own unique local services, which can range from extensive conferences to large file libraries.

1.3 PUBLIC-ACCESS INTERNET PROVIDERS

When you have your communications program dial one of these host systems, one of two things will happen when you connect. You'll either see a lot of gibberish on your screen, or you'll be asked to log in. If you see gibberish, chances are you have to change your software's parameters (to 7-1-E or 8-1-N as the case may be). Hang up, make the change and then dial in again. When you've connected, chances are you'll see something like this:

Welcome to THE WORLD

Public Access UNIX for the '90s

Login as 'new' if you do not have an account

login:

That last line is a prompt asking you to do something. Since this is your first call, type

new

and hit enter. Often, when you're asked to type something by a host system, you'll be told what to type in quotation marks (for example, 'new'). Don't include the quotation marks. Repeat: Don't include the quotation marks. What you see next depends on the system, but will generally consist of information about its costs and services (you might want to turn on your communication software's logging function, to save this information). You'll likely be asked if you want to establish an account now or just look around the system. You'll also likely be asked for your "user name." This is not your full name, but a one-word name you want to use while online. It can be any combination of letters or numbers, all in lower case. Many people use their first initial and last name (for example, "jdoe"); their first name and the first letter of their last name (for example, "johnd"); or their initials ("jxd"). Others use a nickname. You might want to think about this for a second, because this user name will become part of your electronic-mail address (see chapter 2 for more on that). The one exception are the various Free-Net systems, all of which assign you a user name consisting of an arbitrary sequence of letters and numbers. You are now on the Net. Look around the system. See if there are any help files for you to read. If it's a menu-based host system, choose different options just to see what happens. Remember: You can't break anything. The more you play, the more comfortable you'll be. What follows is a list of public-access Internet sites, which are computer systems that offer access to the Net. All offer international e-mail and Usenet (international conferences). In addition, they offer:

FTP: File-transfer protocol - access to hundreds of file libraries (everything from computer software to historical documents to song lyrics). You'll be able to transfer these files from the Net to your own computer.

Telnet: Access to databases, computerized library card catalogs, weather reports and other information services, as well as live, online games that let you compete with players from around the world.

Additional services that may be offered include:

WAIS: Wide-area Information Server; a program that can search dozens of databases in one search.

Gopher: A program that gives you easy access to dozens of other online databases and services by making selections on a menu. You'll also be able to use these to copy text files and some programs to your mailbox.

IRC: Internet Relay Chat, a CB simulator that lets you have live keyboard chats with people around the world.

However, even on systems that do not provide these services directly, you will be able to use a number of them through telnet (see Chapter 6). In the list that follows, systems that let you access services through menus are noted; otherwise assume that when you connect, you'll be dumped right into Unix (a.k.a. MS-DOS with a college degree). Several of these sites are available nationwide through national data networks such as the CompuServe Packet Network and SprintNet. Please note that all listed charges are subject to change. Many sites require new or prospective users to log on a particular way on their first call; this list provides the name you'll use in such cases.

1.4 IF YOUR TOWN HAS NO DIRECT ACCESS

If you don't live in an area with a public-access site, you'll still be able to connect to the Net. Several services offer access through national data networks such as the CompuServe Packet Network and SprintNet, which have dozens, even hundreds of local dial-in numbers across the country. These include Holonet in Berkeley, Calf., Portal in Cupertino, Calf., the WELL in Sausalito, Calf., Dial 'N CERF in San Diego, Calf., the World in Brookline, Mass., and Michnet in Ann Arbor, Mich. Dial 'N CERF offers access through an 800 number. Expect to pay from $2 to $12 an hour to use these networks, above each provider's basic charges. The exact amount depends on the network, time of day and type of modem you use. For more information, contact the above services. Four other providers deliver Net access to users across the country: Delphi, based in Cambridge, Mass., is a consumer-oriented network much like CompuServe or America Online - only it now offers subscribers access to Internet services. Delphi charges: $3 a month for Internet access, in addition to standard charges. These are $10 a month for four hours of off-peak (non-working hours) access a month and $4 an hour for each additional hour or $20 for 20 hours of access a month and $1.80 an hour for each additional hour. For more information, call (800) 695-4005. BIX (the Byte Information Exchange) offers FTP, Telnet and e-mail access to the Internet as part of their basic service. Owned by the same company as Delphi, it also offers 20 hours of access a month for $20. For more information, call (800) 695-4775. PSI, based in Reston, Va., provides nationwide access to Internet services through scores of local dial-in numbers to owners of IBM and compatible computers. PSILink. which includes access to e-mail, Usenet and ftp, costs $29 a month, plus a one-time $19 registration fee. Special software is required, but is available free from PSI. PSI's Global Dialup Service provides access to telnet for $39 a month plus a one-time $39 set-up fee. For more information, call (800) 82PSI82 or (703) 620-6651. NovX Systems Integration, based in Seattle, Washington, offers full Internet access through an 800 number reachable across the United States. There is a $24.95 setup fee, in addition to a monthly fee of $19.95 and a $10.5 hourly charge. For more information, call (206) 447-0800.

1.5 NET ORIGINS

In the 1960s, researchers began experimenting with linking computers to each other and to people through telephone hook-ups, using funds from the U.S Defense Department's Advanced Research Projects Agency (ARPA). ARPA wanted to see if computers in different locations could be linked using a new technology known as packet switching. This technology, in which data meant for another location is broken up into little pieces, each with its own "forwarding address" had the promise of letting several users share just one communications line. Just as important, from ARPA's viewpoint, was that this allowed for creation of networks that could automatically route data around downed circuits or computers. ARPA's goal was not the creation of today's international computer-using community, but development of a data network that could survive a nuclear attack. Previous computer networking efforts had required a line between each computer on the network, sort of like a one-track train route. The packet system allowed for creation of a data highway, in which large numbers of vehicles could essentially share the same lane. Each packet was given the computer equivalent of a map and a time stamp, so that it could be sent to the right destination, where it would then be reassembled into a message the computer or a human could use. This system allowed computers to share data and the researchers to exchange electronic mail, or e-mail. In itself, e-mail was something of a revolution, offering the ability to send detailed letters at the speed of a phone call. As this system, known as ARPANet, grew, some enterprising college students (and one in high school) developed a way to use it to conduct online conferences. These started as science-oriented discussions, but they soon branched out into virtually every other field, as people recognized the power of being able to "talk" to hundreds, or even thousands, of people around the country. In the 1970s, ARPA helped support the development of rules, or protocols, for transferring data between different types of computer networks. These "internet" (from "internetworking") protocols made it possible to develop the worldwide Net we have today that links all sorts of computers across national boundaries. By the close of the 1970s, links developed between ARPANet and counterparts in other countries. The world was now tied together in a computer web. In the 1980s, this network of networks, which became known collectively as the Internet, expanded at a phenomenal rate. Hundreds, then thousands, of colleges, research companies and government agencies began to connect their computers to this worldwide Net. Some enterprising hobbyists and companies unwilling to pay the high costs of Internet access (or unable to meet stringent government regulations for access) learned how to link their own systems to the Internet, even if "only" for e-mail and conferences. Some of these systems began offering access to the public. Now anybody with a computer and modem - and persistence - could tap into the world. In the 1990s, the Net continues to grow at exponential rates. Some estimates are that the volume of messages transferred through the Net grows 20 percent a month. In response, government and other users have tried in recent years to expand the Net itself. Once, the main Net "backbone" in the U.S. moved data at 56,000 bits per second. That proved too slow for the ever increasing amounts of data being sent over it, and in recent years the maximum speed was increased to 1.5 million and then 45 million bits per second. Even before the Net was able to reach that latter speed, however, Net experts were already figuring out ways to pump data at speeds of up to 2 billion bits per second - fast enough to send the entire Encyclopedia Britannica across the country in just one or two seconds. Another major change has been the development of commercial services that provide internetworking services at speeds comparable to those of the government system. In fact, by mid-1994, the U.S. government will remove itself from any day-to-day control over the workings of the Net, as regional and national providers continue to expand.

1.6 HOW IT WORKS

The worldwide Net is actually a complex web of smaller regional networks. To understand it, picture a modern road network of trans- continental superhighways connecting large cities. From these large cities come smaller freeways and parkways to link together small towns, whose residents travel on slower, narrow residential ways. The Net superhighway is the high-speed Internet. Connected to this are computers that use a particular system of transferring data at high speeds. In the U.S., the major Internet "backbone" theoretically can move data at rates of 45 million bits per second (compare this to the average home modem, which has a top speed of roughly 9,600 to 14,400 bits per second). Connected to the backbone computers are smaller networks serving particular geographic regions, which generally move data at speeds around 1.5 million bits per second. Feeding off these in turn are even smaller networks or individual computers. Unlike with commercial networks such as CompuServe or Prodigy, there is no one central computer or computers running the Internet - its resources are to be found among thousands of individual computers. This is both its greatest strength and its greatest weakness. The approach means it is virtually impossible for the entire Net to crash at once - even if one computer shuts down, the rest of the network stays up. The design also reduces the costs for an individual or organization to get onto the network. But thousands of connected computers can also make it difficult to navigate the Net and find what you want - especially as different computers may have different commands for plumbing their resources. It is only recently that Net users have begun to develop the sorts of navigational tools and "maps" that will let neophytes get around without getting lost. Nobody really knows how many computers and networks actually make up this Net. Some estimates say there are now as many as 5,000 networks connecting nearly 2 million computers and more than 15 million people around the world. Whatever the actual numbers, however, it is clear they are only increasing. The Net is more than just a technological marvel. It is human communication at its most fundamental level. The pace may be a little quicker when the messages race around the world in a few seconds, but it's not much different from a large and interesting party. You'll see things in cyberspace that will make you laugh; you'll see things that will anger you. You'll read silly little snippets and new ideas that make you think. You'll make new friends and meet people you wish would just go away. Major network providers continue to work on ways to make it easier for users of one network to communicate with those of another. Work is underway on a system for providing a universal "white pages" in which you could look up somebody's electronic-mail address, for example. This connectivity trend will likely speed up in coming years as users begin to demand seamless network access, much as telephone users can now dial almost anywhere in the world without worrying about how many phone companies actually have to connect their calls. And today, the links grow ever closer between the Internet and such commercial networks as CompuServe and Prodigy, whose users can now exchange electronic mail with their Internet friends. Some commercial providers, such as Delphi and America Online, are working to bring their subscribers direct access to Internet services. And as it becomes easier to use, more and more people will join this worldwide community we call the Net. Being connected to the Net takes more than just reading conferences and logging messages to your computer; it takes asking and answering questions, exchanging opinions - getting involved. If you choose to go forward, to use and contribute, you will become a citizen of Cyberspace. If you're reading these words for the first time, this may seem like an amusing but unlikely notion - that one could "inhabit" a place without physical space. But put a mark beside these words. Join the Net and actively participate for a year. Then re-read this passage. It will no longer seem so strange to be a "citizen of Cyberspace." It will seem like the most natural thing in the world. And that leads to another fundamental thing to remember:

You can't break the Net!

As you travel the Net, your computer may freeze, your screen may erupt into a mass of gibberish. You may think you've just disabled a million-dollar computer somewhere - or even your own personal computer. Sooner or later, this feeling happens to everyone - and likely more than once. But the Net and your computer are hardier than you think, so relax. You can no more break the Net than you can the phone system. If something goes wrong, try again. If nothing at all happens, you can always disconnect. If worse comes to worse, you can turn off your computer. Then take a deep breath. And dial right back in. Leave a note for the person who runs the computer to which you've connected to ask for advice. Try it again. Persistence pays. Stay and contribute. The Net will be richer for it - and so will you.

1.7 WHEN THINGS GO WRONG

* Your computer connects with a public-access site and get gibberish on your screen. If you are using parameters of 8-1-N, try 7-1-e (or vice-versa). If that doesn't work, try another modem speed. * You have your computer dial a public-access site, but nothing happens. Check the phone number you typed in. If correct, turn on your modem's speaker (on Hayes-compatible modems, you can usually do this by typing ATM1 in your communications software's "terminal mode"). If the phone just rings and rings, the public-access site could be down for maintenance or due to a crash or some other problem. If you get a "connect" message, but nothing else, try hitting enter or escape a couple of times. * You try to log in, but after you type your password, nothing happens, or you get a "timed out" message followed by a disconnect. Re-dial the number and try it again. * Always remember, if you have a problem that just doesn't go away, ask! Ask your system administrator, ask a friend, but ask. Somebody will know what to do.

1.8 FYI

The Net grows so fast that even the best guide to its resources would be somewhat outdated the day it was printed. At the end of each chapter, however, you'll find FYI pointers to places on the Net where you can go for more information or to keep updated on new resources and services. Peter Kaminski maintains a list of systems that provide public access to Internet services. It's availble on the network itself, which obviously does you little good if you currently have no access, but which can prove invaluable should you move or want to find a new system. Look for his "PDIAL" file in the alt.bbs.lists or news.answers newsgroups in Usenet (for information on accessing Usenet, see Chapter 3). Steven Levy's book, "Hackers: Heroes of the Computer Revolution," (Anchor Press/Doubleday, 1984). describes the early culture and ethos that ultimately resulted in the Internet and Usenet. John Quarterman's "The Matrix: Computer Networks and Conferencing Systems Worldwide" (Digital Press, 1990) is an exhaustive look at computer networks and how they connect with each other. You'll find numerous documents about the Internet, its history and its resources in the pub/Net_info directory on the Electronic Frontier Foundation's FTP server (see chapter 7 to decipher this).

2.1 THE BASICS

Electronic mail, or e-mail, is your personal connection to the world of the Net. All of the millions of people around the world who use the Net have their own e-mail addresses. A growing number of "gateways" tie more and more people to the Net every day. When you logged onto the host system you are now using, it automatically generated an address for you, as well. The basic concepts behind e-mail parallel those of regular mail. You send mail to people at their particular addresses. In turn, they write to you at your e-mail address. You can subscribe to the electronic equivalent of magazines and newspapers. You might even get electronic junk mail. E-mail has two distinct advantages over regular mail. The most obvious is speed. Instead of several days, your message can reach the other side of the world in hours, minutes or even seconds (depending on where you drop off your mail and the state of the connections between there and your recipient). The other advantage is that once you master the basics, you'll be able to use e-mail to access databases and file libraries. You'll see how to do this later, along with learning how to transfer program and data files through e-mail. E-mail also has advantages over the telephone. You send your message when it's convenient for you. Your recipients respond at their convenience. No more telephone tag. And while a phone call across the country or around the world can quickly result in huge phone bills, e-mail lets you exchange vast amounts of mail for only a few pennies - even if the other person is in New Zealand. E-mail is your connection to help - your Net lifeline. The Net can sometimes seem a frustrating place! No matter how hard you try, no matter where you look, you just might not be able to find the answer to whatever is causing you problems. But when you know how to use e-mail, help is often just a few keystrokes away: you can ask your system administrator or a friend for help in an e-mail message. The quickest way to start learning e-mail is to send yourself a message. Most public-access sites actually have several different types of mail systems, all of which let you both send and receive mail. We'll start with the simplest one, known, appropriately enough, as "mail," and then look at a couple of other interfaces. At your host system's command prompt, type:

mail username

where username is the name you gave yourself when you first logged on. Hit enter. The computer might respond with

subject:

Type

test

or, actually, anything at all (but you'll have to hit enter before you get to the end of the screen). Hit enter. The cursor will drop down a line. You can now begin writing the actual message. Type a sentence, again, anything at all. And here's where you hit your first Unix frustration, one that will bug you repeatedly: you have to hit enter before you get to the very end of the line. Just like typewriters, many Unix programs have no word-wrapping (although there are ways to get some Unix text processors, such as emacs, to word-wrap). When done with your message, hit return. Now hit control-D (the control and the D keys at the same time). This is a Unix command that tells the computer you're done writing and that it should close your "envelope" and mail it off (you could also hit enter once and then, on a blank line, type a period at the beginning of the line and hit enter again). You've just sent your first e-mail message. And because you're sending mail to yourself, rather than to someone somewhere else on the Net, your message has already arrived, as we'll see in a moment. If you had wanted, you could have even written your message on your own computer and then uploaded it into this electronic "envelope." There are a couple of good reasons to do this with long or involved messages. One is that once you hit enter at the end of a line in "mail" you can't readily fix any mistakes on that line (unless you use some special commands to call up a Unix text processor). Also, if you are paying for access by the hour, uploading a prepared message can save you money. Remember to save the document in ASCII or text format. Uploading a document you've created in a word processor that uses special formatting commands (which these days means many programs) will cause strange effects. When you get that blank line after the subject line, upload the message using the ASCII protocol. Or you can copy and paste the text, if your software allows that. When done, hit control-D as above. Now you have mail waiting for you. Normally, when you log on, your public-access site will tell you whether you have new mail waiting. To open your mailbox and see your waiting mail, type

mail

and hit enter.

When the host system sees "mail" without a name after it, it

knows you want to look in your mailbox rather than send a message.

Your screen, on a plain-vanilla Unix system will display:

Mail version SMI 4.0 Mon Apr 24 18:34:15 PDT 1989 Type ? for help.

"/usr/spool/mail/adamg": 1 message 1 new 1 unread

>N 1 adamg Sat Jan 15 20:04 12/290 test

Ignore the first line; it's just computerese of value only to the people who run your system. You can type a question mark and hit return, but unless you're familiar with Unix, most of what you'll see won't make much sense at this point. The second line tells you the directory on the host system where your mail messages are put, which again, is not something you'll likely need to know. The second line also tells you how many messages are in your mailbox, how many have come in since the last time you looked and how many messages you haven't read yet. It's the third line that is of real interest - it tells you who the message is from, when it arrived, how many lines and characters it takes up, and what the subject is. The "N" means it is a new message - it arrived after the last time you looked in your mailbox. Hit enter. And there's your message - only now it's a lot longer than what you wrote!

Subject: test

Status: R

This is only a test!

Whoa! What is all that stuff? It's your message with a postmark gone mad. Just as the postal service puts its marks on every piece of mail it handles, so do Net postal systems. Only it's called a "header" instead of a postmark. Each system that handles or routes your mail puts its stamp on it. Since many messages go through a number of systems on their way to you, you will often get messages with headers that seem to go on forever. Among other things, a header will tell you exactly when a message was sent and received (even the difference between your local time and Greenwich Mean Time - as at the end of line 4 above). If this had been a long message, it would just keep scrolling across and down your screen - unless the people who run your public- access site have set it up to pause every 24 lines. One way to deal with a message that doesn't stop is to use your telecommunication software's logging or text-buffer function. Start it before you hit the number of the message you want to see. Your computer will ask you what you want to call the file you're about to create. After you name the file and hit enter, type the number of the message you want to see and hit enter. When the message finishes scrolling, turn off the text-buffer function. The message is now saved in your computer. This way, you can read the message while not connected to the Net (which can save you money if you're paying by the hour) and write a reply offline. But in the meantime, now what? You can respond to the message, delete it or save it. To respond, type a lowercase r and hit enter. You'll get something like this:

To: adamg

Subject: Re: test

Note that this time, you don't have to enter a user name. The computer takes it from the message you're replying to and automatically addresses your message to its sender. The computer also automatically inserts a subject line, by adding "Re:" to the original subject. From here, it's just like writing a new message. But say you change your mind and decide not to reply after all. How do you get out of the message? Hit control-C once. You'll get this:

(Interrupt - one more to kill letter)

If you hit control-C once more, the message will disappear and you'll get back to your mail's command line. Now, if you type a lowercase d and then hit enter, you'll delete the original message. Type a lowercase q to exit your mailbox. If you type a q without first hitting d, your message is transferred to a file called mbox. This file is where all read, but un-deleted messages go. If you want to leave it in your mailbox for now, type a lowercase x and hit enter. This gets you out of mail without making any changes. The mbox file works a lot like your mailbox. To access it, type

mail -f mbox

at your host system's command line and hit enter. You'll get a menu identical to the one in your mailbox from which you can read these old messages, delete them or respond to them. It's probably a good idea to clear out your mailbox and mbox file from time to time, if only to keep them uncluttered. Are there any drawbacks to e-mail? There are a few. One is that people seem more willing to fly off the handle electronically than in person, or over the phone. Maybe it's because it's so easy to hit r and reply to a message without pausing and reflecting a moment. That's why we have smileys (see section 2.4)! There's no online equivalent yet of a return receipt: chances are your message got to where it's going, but there's no absolute way for you to know for sure unless you get a reply from the other person. So now you're ready to send e-mail to other people on the Net. Of course, you need somebody's address to send them mail. How do you get it? Alas, the simplest answer is not what you'd call the most elegant: you call them up on the phone or write them a letter on paper and ask them. Residents of the electronic frontier are only beginning to develop the equivalent of phone books, and the ones that exist today are far from complete (still, later on, in Chapter 6, we'll show you how to use some of these directories). Eventually, you'll start corresponding with people, which means you'll want to know how to address mail to them. It's vital to know how to do this, because the smallest mistake - using a comma when you should have used a period, for instance, can bounce the message back to you, undelivered. In this sense, Net addresses are like phone numbers: one wrong digit and you get the wrong person. Fortunately, most net addresses now adhere to a relatively easy-to-understand system. Earlier, you sent yourself a mail message using just your user- name. This was sort of like making a local phone call - you didn't have to dial a 1 or an area code. This also works for mail to anybody else who has an account on the same system as you. Sending mail outside of your system, though, will require the use of the Net equivalent of area codes, called "domains." A basic Net address will look something like this:

tomg@world.std.com

Tomg is somebody's user ID, and he is at (hence the @ sign) a site (or in Internetese, a "domain") known as std.com. Large organizations often have more than one computer linked to the Internet; in this case, the name of the particular machine is world (you will quickly notice that, like boat owners, Internet computer owners always name their machines). Domains tell you the name of the organization that runs a given e-mail site and what kind of site it is or, if it's not in the U.S., what country it's located in. Large organizations may have more than one computer or gateway tied to the Internet, so you'll often see a two-part domain name; and sometimes even three- or four-part domain names. In general, American addresses end in an organizational suffix, such as ".edu," which means the site is at a college or university. Other American suffixes include:

.com for businesses .org for non-profit organizations .gov and .mil for government and military agencies .net for companies or organizations that run large networks.

Sites in the rest of the world tend to use a two-letter code that represents their country. Most make sense, such as .ca for Canadian sites, but there are a couple of seemingly odd ones. Swiss sites end in .ch, while South African ones end in .za. Some U.S. sites have followed this international convention (such as well.sf.ca.us). You'll notice that the above addresses are all in lower-case. Unlike almost everything else having anything at all to do with Unix, most Net mailing systems don't care about case, so you generally don't have to worry about capitalizing e-mail addresses. Alas, there are a few exceptions - some public-access sites do allow for capital letters in user names. When in doubt, ask the person you want to write to, or let her send you a message first (recall how a person's e-mail address is usually found on the top of her message). The domain name, the part of the address after the @ sign, never has to be capitalized. It's all a fairly simple system that works very well, except, again, it's vital to get the address exactly right - just as you have to dial a phone number exactly right. Send a message to tomg@unm.edu (which is the University of New Mexico) when you meant to send it to tomg@umn.edu (the University of Minnesota), and your letter will either bounce back to you undelivered, or go to the wrong person. If your message is bounced back to you as undeliverable, you'll get an ominous looking-message from MAILER-DAEMON (actually a rather benign Unix program that exists to handle mail), with an evil-looking header followed by the text of your message. Sometimes, you can tell what went wrong by looking at the first few lines of the bounced message. Besides an incorrect address, it's possible your host system does not have the other site in the "map" it maintains of other host systems. Or you could be trying to send mail to another network, such as Bitnet or CompuServe, that has special addressing requirements. Sometimes, figuring all this out can prove highly frustrating. But remember the prime Net commandment: Ask. Send a message to your system administrator. He or she might be able to help decipher the problem. There is one kind of address that may give your host system particular problems. There are two main ways that Unix systems exchange mail. One is known as UUCP and started out with a different addressing system than the rest of the Net. Most UUCP systems have since switched over to the standard Net addressing system, but a few traditional sites still cling to their original type, which tends to have lots of exclamation points in it, like this:

uunet!somesite!othersite!mybuddy

The problem for many host sites is that exclamation points (also known as "bangs") now mean something special in the more common systems or "shells" used to operate many Unix computers. This means that addressing mail to such a site (or even responding to a message you received from one) could confuse the poor computer to no end and your message never gets sent out. If that happens, try putting backslashes in front of each exclamation point, so that you get an address that looks like this:

uunet\!somesite\!othersite\!mybuddy

Note that this means you may not be able to respond to such a message by typing a lowercase r - you may get an error message and you'll have to create a brand-new message. If you want to get a taste of what's possible through e-mail, start an e-mail message to

almanac@oes.orst.edu

Leave the "subject:" line blank. As a message, write this:

send quote

Or, if you're feeling a little down, write this instead:

send moral-support

In either case, you will get back a message within a few seconds to a few hours (depending on the state of your host system's Internet connection). If you simply asked for a quote, you'll get back a fortune-cookie-like saying. If you asked for moral support, you'll also get back a fortune-cookie-like saying, only supposedly more uplifting. This particular "mail server" is run by Oregon State University. Its main purpose is actually to provide a way to distribute agricultural information via e-mail. If you'd like to find out how to use the server's full range of services, send a message to its address with this line in it:

send help

You'll quickly get back a lengthy document detailing just what's available and how to get it. Feeling opinionated? Want to give the President of the United States a piece of your mind? Send a message to president@whitehouse.gov. Or if the vice president will do, write vice-president@whitehouse.gov. The "mail" program is actually a very powerful one and a Netwide standard, at least on Unix computers. But it can be hard to figure out - you can type a question mark to get a list of commands, but these may be of limited use unless you're already familiar with Unix. Fortunately, there are a couple of other mail programs that are easier to use.

2.2 ELM - A BETTER WAY

Elm is a combination mailbox and letter-writing system that uses menus to help you navigate through mail. Most Unix-based host systems now have it online. To use it, type

elm

and hit enter. You'll get a menu of your waiting mail, along with a list of commands you can execute, that will look something like this:

Mailbox is '/usr/spool/mail/adamg' with 38 messages [ELM 2.3 PL11]

1 Sep 1 Christopher Davis (13) here's another message. 2 Sep 1 Christopher Davis (91) This is a message from Eudora 3 Aug 31 Rita Marie Rouvali (161) First Internet Hunt !!! (fwd) 4 Aug 31 Peter Scott/Manage (69) New File University of Londo 5 Aug 30 Peter Scott/Manage (64) New File X.500 service at A 6 Aug 30 Peter Scott/Manage (39) New File DATAPAC Informatio 7 Aug 28 Peter Scott/Manage (67) Proposed Usenet group for HYTELNET n 8 Aug 28 Peter Scott/Manage (56) New File JANET Public Acces 9 Aug 26 Helen Trillian Ros (15) Tuesday 10 Aug 26 Peter Scott/Manage (151) Update Oxford University OU

You can use any of the following commands by pressing the first character;

d)elete or u)ndelete mail, m)ail a message, r)eply or f)orward mail, q)uit

To read a message, press . j = move down, k = move up, ? = help

Each line shows the date you received the message, who sent it, how many lines long the message is, and the message's subject. If you are using VT100 emulation, you can move up and down the menu with your up and down arrow keys. Otherwise, type the line number of the message you want to read or delete and hit enter. When you read a message, it pauses every 24 lines, instead of scrolling until it's done. Hit the space bar to read the next page. You can type a lowercase r to reply or a lower-case q or i to get back to the menu (the I stands for "index"). At the main menu, hitting a lowercase m followed by enter will let you start a message. To delete a message, type a lower-case d. You can do this while reading the message. Or, if you are in the menu, move the cursor to the message's line and then hit d. When you're done with elm, type a lower-case q. The program will ask if you really want to delete the messages you marked. Then, it will ask you if you want to move any messages you've read but haven't marked for deletion to a "received" file. For now, hit your n key. Elm has a major disadvantage for the beginner. The default text editor it generally calls up when you hit your r or m key is often a program called emacs. Unixoids swear by emacs, but everybody else almost always finds it impossible. Unfortunately, you can't always get away from it (or vi, another text editor often found on Unix systems), so later on we'll talk about some basic commands that will keep you from going totally nuts. If you want to save a message to your own computer, hit s, either within the message or with your cursor on the message entry in the elm menu. A filename will pop up. If you do not like it, type a new name (you won't have to backspace). Hit enter, and the message will be saved with that file name in your "home directory" on your host system. After you exit elm, you can now download it (ask your system administrator for specifics on how to download - and upload - such files).

2.3 PINE - AN EVEN BETTER WAY

Pine is based on elm but includes a number of improvements that make it an ideal mail system for beginners. Like elm, pine starts you with a menu. It also has an "address book" feature that is handy for people with long or complex e-mail addresses. Hitting A at the main menu puts you in the address book, where you can type in the person's first name (or nickname) followed by her address. Then, when you want to send that person a message, you only have to type in her first name or nickname, and pine automatically inserts her actual address. The address book also lets you set up a mailing list. This feature allows you to send the same message to a number of people at once. What really sets pine apart is its built-in text editor, which looks and feels a lot more like word-processing programs available for MS-DOS and Macintosh users. Not only does it have word wrap (a revolutionary concept if ever there was one), it also has a spell-checker and a search command. Best of all, all of the commands you need are listed in a two-line mini-menu at the bottom of each screen. The commands look like this:

^W Where is

The little caret is a synonym for the key marked "control" on your keyboard. To find where a particular word is in your document, you'd hit your control key and your W key at the same time, which would bring up a prompt asking you for the word to look for. Some of pine's commands are a tad peculiar (control-V for "page down" for example), which comes from being based on a variant of emacs (which is utterly peculiar). But again, all of the commands you need are listed on that two-line mini-menu, so it shouldn't take you more than a couple of seconds to find the right one. To use pine, type

pine

at the command line and hit enter. It's a relatively new program, so some systems may not yet have it online. But it's so easy to use, you should probably send e-mail to your system administrator urging him to get it!

2.4 SMILEYS

When you're involved in an online discussion, you can't see the smiles or shrugs that the other person might make in a live conversation to show he's only kidding. But online, there's no body language. So what you might think is funny, somebody else might take as an insult. To try to keep such misunderstandings from erupting into bitter disputes, we have smileys. Tilt your head to the left and look at the following sideways. :-). Or simply :). This is your basic "smiley." Use it to indicate people should not take that comment you just made as seriously as they might otherwise. You make a smiley by typing a colon, a hyphen and a right parenthetical bracket. Some people prefer using the word "grin," usually in this form:

Sometimes, though, you'll see it as *grin* or even just for short.

Some other smileys include:

;-) Wink;

:-( Frown;

:-O Surprise;

8-) Wearing glasses;

=|:-)= Abe Lincoln.

OK, so maybe the last two are a little bogus :-).

2.5 SENDING E-MAIL TO OTHER NETWORKS

There are a number of computer networks that are not directly part of the Net, but which are now connected through "gateways" that allow the passing of e-mail. Here's a list of some of the larger networks, how to send mail to them and how their users can send mail to you:

America Online

Remove any spaces from a user's name and append "aol.com," to get

user@aol.com

America Online users who want to send mail to you need only put your Net address in the "to:" field before composing a message.

ATTMail

Address your message to user@attmail.com.

From ATTMail, a user would send mail to you in this form:

internet!domain!user

So if your address were nancyr@world.std.com, your correspondent would send a message to you at

internet!world.std.com!nancyr

Bitnet

Users of Bitnet (and NetNorth in Canada and EARN in Europe) often have addresses in this form: IZZY@INDVMS. If you're lucky, all you'll have to do to mail to that address is add "bitnet" at the end, to get izzy@indvms.bitnet. Sometimes, however, mail to such an address will bounce back to you, because Bitnet addresses do not always translate well into an Internet form. If this happens, you can send mail through one of two Internet/Bitnet gateways. First, change the @ in the address to a %, so that you get username%site.bitnet. Then add either @vm.marist.edu or @cunyvm.cuny.edu, so that, with the above example, you would get izzy%indyvms.bitnet@vm.marist.edu or izzy%indvyvms.bitnet@cunyvm.cuny.edu Bitnet users have it a little easier: They can usually send mail directly to your e-mail address without fooling around with it at all. So send them your address and they should be OK.

CompuServe

CompuServe users have numerical addresses in this form: 73727,545. To send mail to a CompuServe user, change the comma to a period and add "@compuserve.com"; for example: 73727.545@compuserve.com. Note that some CompuServe users must pay extra to receive mail from the Internet. If you know CompuServe users who want to send you mail, tell them to GO MAIL and create a mail message. In the address area, instead of typing in a CompuServe number, have them type your address in this form:

>INTERNET:YourID@YourAddress.

For example, >INTERNET:adamg@world.std.com. Note that both the ">" and the ":" are required.

Delphi

To send mail to a Delphi user, the form is username@delphi.com.

Fidonet

To send mail to people using a Fidonet BBS, you need the name they use to log onto that system and its "node number.'' Fidonet node numbers or addresses consist of three numbers, in this form: 1:322/190. The first number tells which of several broad geographic zones the BBS is in (1 represents the U.S. and Canada, 2 Europe and Israel, 3 Pacific Asia, 4 South America). The second number represents the BBS's network, while the final number is the BBS's "FidoNode'' number in that network. If your correspondent only gives you two numbers (for example, 322/190), it means the system is in zone 1. Now comes the tricky part. You have to reverse the numbers and add to them the letters f, n and z (which stand for "FidoNode,''"network,'' and "zone'). For example, the address above would become

f190.n322.z1.

Now add "fidonet.org'' at the end, to get

f190.n322.z1.fidonet.org. Then add "FirstName.LastName@', to get

FirstName.LastName@f190.n322.z1.fidonet.org

Note the period between the first and last names. Also, some countries now have their own Fidonet "backbone" systems, which might affect addressing. For example, were the above address in Germany, you would end it with "fido.de" instead of "fidonet.org." Whew! The reverse process is totally different. First, the person has to have access to his or her BBS's "net mail" area and know the Fidonet address of his or her local Fidonet/UUCP gateway (often their system operator will know it). Your Fidonet correspondent should address a net-mail message to UUCP (not your name) in the "to:" field. In the node-number field, they should type in the node number of the Fidonet/UUCP gateway (if the gateway system is in the same regional network as their system, they need only type the last number, for example, 390 instead of 322/390). Then, the first line of the message has to be your Internet address, followed by a blank line. After that, the person can write the message and send it. Because of the way Fidonet moves mail, it could take a day or two for a message to be delivered in either direction. Also, because many Fidonet systems are run as hobbies, it is considered good form to ask the gateway sysop's permission if you intend to pass large amounts of mail back and forth. Messages of a commercial nature are strictly forbidden (even if it's something the other person asked for). Also, consider it very likely that somebody other than the recipient will read your messages.

GEnie

To send mail to a GEnie user, add "@genie.com" to the end of the GEnie user name, for example: walt@genie.com.

MCIMail

To send mail to somebody with an MCIMail account, add "@mcimail.com to the end of their name or numerical address. For example:

555-1212@mcimail.com

or

jsmith@mcimail.com

Note that if there is more than one MCIMail subscriber with that name, you will get a mail message back from MCI giving you their names and numerical addresses. You'll then have to figure out which one you want and re-send the message.

From MCI, a user would type

Your Name (EMS)

at the "To:" prompt. At the EMS prompt, he or she would type

internet

followed by your Net address at the "Mbx:" prompt.

Peacenet

To send mail to a Peacenet user, use this form:

username@igc.org

Peacenet subscribers can use your regular address to send you mail.

Prodigy

UserID@prodigy.com. Note that Prodigy users must pay extra for

Internet e-mail.

2.6 SEVEN UNIX COMMANDS YOU CAN'T LIVE WITHOUT:

If you connect to the Net through a Unix system, eventually you'll have to come to terms with Unix. For better or worse, most Unix systems do NOT shield you from their inner workings - if you want to copy a Usenet posting to a file, for example, you'll have to use some Unix commands if you ever want to do anything with that file. Like MS-DOS, Unix is an operating system - it tells the computer how to do things. Now while Unix may have a reputation as being even more complex than MS-DOS, in most cases, a few basic, and simple, commands should be all you'll ever need. If your own computer uses MS-DOS or PC-DOS, the basic concepts will seem very familiar - but watch out for the cd command, which works differently enough from the similarly named DOS command that it will drive you crazy. Also, unlike MS-DOS, Unix is case sensitive - if you type commands or directory names in the wrong case, you'll get an error message. If you're used to working on a Mac, you'll have to remember that Unix stores files in "directories" rather than "folders." Unix directories are organized like branches on a tree. At the bottom is the "root" directory, with sub-directories branching off that (and sub-directories in turn can have sub-directories). The Mac equivalent of a Unix sub-directory is a folder within another folder.

cat Equivalent to the MS-DOS "type" command. To pause a file every screen, type

cat file |more

where "file" is the name of the file you want to see. Hitting control-C will stop the display. Alternately, you could type

more file

to achieve the same result. You can also use cat for writing or uploading text files to your name or home directory (similar to the MS-DOS "copy con" command). If you type

cat>test

you start a file called "test." You can either write something simple (no editing once you've finished a line and you have to hit return at the end of each line) or upload something into that file using your communications software's ASCII protocol). To close the file, hit control-D.

cd The "change directory" command. To change from your present directory to another, type

cd directory

and hit enter. Unlike MS-DOS, which uses a \ to denote sub- directories (for example: \stuff\text), Unix uses a / (for example: /stuff/text). So to change from your present directory to the stuff/text sub-directory, you would type

cd stuff/text

and then hit enter. As in MS-DOS, you do not need the first backslash if the subdirectory comes off the directory you're already in. To move back up a directory tree, you would type

cd ..

followed by enter. Note the space between the cd and the two periods - this is where MS-DOS users will really go nuts.

cp Copies a file. The syntax is

cp file1 file2

which would copy file1 to file2 (or overwrite file2 with file1).

ls This command, when followed by enter, tells you what's in the directory, similar to the DOS dir command, except in alphabetical order.

ls | more

will stop the listing every 24 lines - handy if there are a lot of things in the directory. The basic ls command does not list "hidden" files, such as the .login file that controls how your system interacts with Unix. To see these files, type

ls -a or ls -a | more

ls -l will tell you the size of each file in bytes and tell you when each was created or modified.

mv Similar to the MS-DOS rename command.

mv file1 file2

will rename file1 as file2, The command can also be used to move files between directories.

mv file1 News

would move file1 to your News directory.

rm Deletes a file. Type

rm filename

and hit enter (but beware: when you hit enter, it's gone for good).

WILDCARDS: When searching for, copying or deleting files, you can

use "wildcards" if you are not sure of the file's exact name.

ls man*

would find the following files:

manual, manual.txt, man-o-man.

Use a question mark when you're sure about all but one or two characters.

For example,

ls man?

would find a file called mane, but not one called manual.

2.7 WHEN THINGS GO WRONG

* You send a message but get back an ominous looking message from MAILER-DAEMON containing up to several dozen lines of computerese followed by your message. Somewhere in those lines you can often find a clue to what went wrong. You might have made a mistake in spelling the e-mail address. The site to which you're sending mail might have been down for maintenance or a problem. You may have used the wrong "translation" for mail to a non-Internet network. * You call up your host system's text editor to write a message or reply to one and can't seem to get out. If it's emacs, try control-X, control-C (in other words, hit your control key and your X key at the same time, followed by control and C). If worse comes to worse, you can hang up. * In elm, you accidentally hit the D key for a message you want to save. Type the number of the message, hit enter and then U, which will "un-delete" the message. This works only before you exit Elm; once you quit, the message is gone. * You try to upload an ASCII message you've written on your own computer into a message you're preparing in Elm or Pine and you get a lot of left brackets, capital Ms, Ks and Ls and some funny-looking characters. Believe it or not, your message will actually wind up looking fine; all that garbage is temporary and reflects the problems some Unix text processors have with ASCII uploads. But it will take much longer for your upload to finish. One way to deal with this is to call up the simple mail program, which will not produce any weird characters when you upload a text file into a message. Another way (which is better if your prepared message is a response to somebody's mail), is to create a text file on your host system with cat, for example,

cat>file

and then upload your text into that. Then, in elm or pine, you can insert the message with a simple command (control-R in pine, for example); only this time you won't see all that extraneous stuff. * You haven't cleared out your Elm mailbox in awhile, and you accidentally hit "y" when you meant to hit "n" (or vice-versa) when exiting and now all your messages have disappeared. Look in your News directory (at the command line, type: cd News) for a file called recieved. Those are all your messages. Unfortunately, there's no way to get them back into your Elm mailbox - you'll have to download the file or read it online.

3.1 THE GLOBAL WATERING HOLE

Imagine a conversation carried out over a period of hours and days, as if people were leaving messages and responses on a bulletin board. Or imagine the electronic equivalent of a radio talk show where everybody can put their two cents in and no one is ever on hold. Unlike e-mail, which is usually "one-to-one," Usenet is "many-to- many." Usenet is the international meeting place, where people gather to meet their friends, discuss the day's events, keep up with computer trends or talk about whatever's on their mind. Jumping into a Usenet discussion can be a liberating experience. Nobody knows what you look or sound like, how old you are, what your background is. You're judged solely on your words, your ability to make a point. To many people, Usenet IS the Net. In fact, it is often confused with Internet. But it is a totally separate system. All Internet sites CAN carry Usenet, but so do many non-Internet sites, from sophisticated Unix machines to old XT clones and Apple IIs. Technically, Usenet messages are shipped around the world, from host system to host system, using one of several specific Net protocols. Your host system stores all of its Usenet messages in one place, which everybody with an account on the system can access. That way, no matter how many people actually read a given message, each host system has to store only one copy of it. Many host systems "talk" with several others regularly in case one or another of their links goes down for some reason. When two host systems connect, they basically compare notes on which Usenet messages they already have. Any that one is missing the other then transmits, and vice-versa. Because they are computers, they don't mind running through thousands, even millions, of these comparisons every day. Yes, millions. For Usenet is huge. Every day, Usenet users pump upwards of 40 million characters a day into the system - roughly the equivalent of volumes A-G of the Encyclopedia Britannica. Obviously, nobody could possibly keep up with this immense flow of messages. Let's look at how to find conferences and discussions of interest to you. The basic building block of Usenet is the newsgroup, which is a collection of messages with a related theme (on other networks, these would be called conferences, forums, bboards or special-interest groups). There are now more than 5,000 of these newsgroups, in several diferent languages, covering everything from art to zoology, from science fiction to South Africa. Some public-access systems, typically the ones that work through menus, try to make it easier by dividing Usenet into several broad categories. Choose one of those and you're given a list of newsgroups in that category. Then select the newsgroup you're interested in and start reading. Other systems let you compile your own "reading list" so that you only see messages in conferences you want. In both cases, conferences are arranged in a particular hierarchy devised in the early 1980s. Newsgroup names start with one of a series of broad topic names. For example, newsgroups beginning with "comp." are about particular computer- related topics. These broad topics are followed by a series of more focused topics (so that "comp.unix" groups are limited to discussion about Unix). The main hierarchies are:

bionet Research biology bit.listserv Conferences originating as Bitnet mailing lists biz Business comp Computers and related subjects misc Discussions that don't fit anywhere else news News about Usenet itself rec Hobbies, games and recreation sci Science other than research biology soc "Social" groups, often ethnically related talk Politics and related topics alt Controversial or unusual topics; not carried by all sites

In addition, many host systems carry newsgroups for a particular city, state or region. For example, ne.housing is a newsgroup where New Englanders look for apartments. A growing number also carry K12 newsgroups, which are aimed at elementary and secondary teachers and students. And a number of sites carry clari newsgroups, which is actually a commercial service consisting of wire-service stories and a unique online computer news service (more on this in chapter 10).

3.2 NAVIGATING USENET WITH nn

How do you dive right in? As mentioned, on some systems, it's all done through menus - you just keep choosing from a list of choices until you get to the newsgroup you want and then hit the "read" command. On Unix systems, however, you will have to use a "newsreader" program. Two of the more common ones are known as rn (for "read news") and nn (for "no news" - because it's supposed to be simpler to use). For beginners, nn may be the better choice because it works with menus - you get a list of articles in a given newsgroup and then you choose which ones you want to see. To try it out, connect to your host system and, at the command line, type

nn news.announce.newusers

and hit enter. After a few seconds, you should see something like this:

Newsgroup: news.announce.newusers Articles: 22 of 22/1 NEW

- 15:52 - SELECT - help:? ---Top 85%--- Explanatory postings for new users. (Moderated)

Obviously, this is a good newsgroup to begin your exploration of Usenet! Here's what all this means: The first letter on each line is the letter you type to read that particular "article" (it makes sense that a "newsgroup" would have "articles"). Next comes the name of the person who wrote that article, followed by its length, in lines, and what the article is about. At the bottom, you see the local time at your access site, what you're doing right now (i.e., SELECTing articles), which key to hit for some help (the ? key) and how many of the articles in the newsgroup you can see on this screen. The "(moderated)" means the newsgroup has a "moderator" who is the only one who can directly post messages to it. This is generally limited to groups such as this, which contain articles of basic information, or for digests, which are basically online magazines (more on them in a bit). Say you're particularly interested in what "Emily Postnews" has to say about proper etiquette on Usenet. Hit your c key (lower case!), and the line will light up. If you want to read something else, hit the key that corresponds to it. And if you want to see what's on the next page of articles, hit return or your space bar. But you're impatient to get going, and you want to read that article now. The command for that in nn is a capital Z. Hit it and you'll see something like this:

"Dear Emily Postnews"

Emily Postnews, foremost authority on proper net behaviour, gives her advice on how to act on the net.

============================================================================

Dear Miss Postnews: How long should my signature be? - verbose@noisy

A: Dear Verbose: Please try and make your signature as long as you - 09:57 -.announce.newusers- LAST -help:?-Top 4%-

The first few lines are the message's header, similar to the header you get in e-mail messages. Then comes the beginning of the message. The last line tells you the time again, the newsgroup name (or part of it, anyway), the position in your message stack that this message occupies, how to get help, and how much of the message is on screen. If you want to keep reading this message, just hit your space bar (not your enter key!) for the next screen and so on until done. When done, you'll be returned to the newsgroup menu. For now hit Q (upper case this time), which quits you out of nn and returns you to your host system's command line. To get a look at another interesting newsgroup, type

nn comp.risks

and hit enter. This newsgroup is another moderated group, this time a digest of all the funny and frightening ways computers and the people who run and use them can go wrong. Again, you read articles by selecting their letters. If you're in the middle of an article and decide you want to go onto the next one, hit your n key. Now it's time to look for some newsgroups that might be of particular interest to you. Unix host systems that have nn use a program called nngrep (ever get the feeling Unix was not entirely written in English?) that lets you scan newsgroups. Exit nn and at your host system's command line, type

nngrep word

where word is the subject you're interested in. If you use a Macintosh computer, you might try

nngrep mac

You'll get something that looks like this:

alt.music.machines.of.loving.grace alt.religion.emacs comp.binaries.mac comp.emacs comp.lang.forth.mac comp.os.mach comp.sources.mac comp.sys.mac.announce comp.sys.mac.apps comp.sys.mac.comm comp.sys.mac.databases comp.sys.mac.digest comp.sys.mac.games comp.sys.mac.hardware comp.sys.mac.hypercard comp.sys.mac.misc comp.sys.mac.programmer comp.sys.mac.system comp.sys.mac.wanted gnu.emacs.announce gnu.emacs.bug gnu.emacs.gnews gnu.emacs.gnus gnu.emacs.help gnu.emacs.lisp.manual gnu.emacs.sources gnu.emacs.vm.bug gnu.emacs.vm.info gnu.emacs.vms

Note that some of these obviously have something to do with

Macintoshes while some obviously do not; nngrep is not a perfect system.

If you want to get a list of ALL the newsgroups available on your host

system, type

nngrep -a |more

or nngrep -a |pg

and hit enter (which one to use depends on the Unix used on your host system; if one doesn't do anything, try the other). You don't absolutely need the |more or |pg, but if you don't include it, the list will keep scrolling, rather than pausing every 24 lines. If you are in nn, hitting a capital Y will bring up a similar list. Typing "nn newsgroup" for every newsgroup can get awfully tiring after awhile. When you use nn, your host system looks in a file called .newsrc. This is basically a list of every newsgroup on the host system along with notations on which groups and articles you have read (all maintained by the computer). You can also use this file to create a "reading list" that brings up each newsgroup to which you want to "subscribe." To try it out, type

nn

without any newsgroup name, and hit enter. Unfortunately, you will start out with a .newsrc file that has you "subscribed" to every single newsgroup on your host system! To delete a newsgroup from your reading list, type a capital U while its menu is on the screen. The computer will ask you if you're sure you want to "unsubscribe." If you then hit a Y, you'll be unsubscribed and put in the next group. With many host systems carrying thousands of newsgroups, this will take you forever. Fortunately, there are a couple of easier ways to do this. Both involve calling up your .newsrc file in a word or text processor. In a .newsrc file, each newsgroup takes up one line, consisting of the group's name, an exclamation point or a colon and a range of numbers. Newsgroups with a colon are ones to which you are subscribed; those followed by an exclamation point are "un-subscribed." To start with a clean slate, then, you have to change all those colons to exclamation points. If you know how to use emacs or vi, call up the .newsrc file (you might want to make a copy of .newsrc first, just in case), and use the search-and-replace function to make the change. If you're not comfortable with these text processor, you can download the .newsrc file, make the changes on your own computer and then upload the revised file. Before you download the file, however, you should do a couple of things. One is to type

cp .newsrc temprc

and hit enter. You will actually download this temprc file (note the name does not start with a period - some computers, such as those using MS-DOS, do not allow file names starting with periods). After you download the file, open it in your favorite word processor and use its search-and-replace function to change the exclamation points to colons. Be careful not to change anything else! Save the document in ASCII or text format. Dial back into your host system. At the command line, type

cp temprc temprc1

and hit enter. This new file will serve as your backup .newsrc file just in case something goes wrong. Upload the temprc file from your computer. This will overwrite the Unix system's old temprc file. Now type

cp temprc .newsrc

and hit enter. You now have a clean slate to start creating a reading list.

3.3 nn COMMANDS

To mark a specific article for reading, type the letter next to it (in lower case). To mark a specific article and all of its responses, type the letter and an asterisk, for example:

a*

To un-select an article, type the letter next to it (again, in lower case).

C Cancels an article (around the world) that you wrote. Every article posted on Usenet has a unique ID number. Hitting a capital C sends out a new message that tells host systems that receive it to find earlier message and delete it.

F To post a public response, or follow-up. If selected while still on a newsgroup "page", asks you which article to follow up. If selected while in a specific article, will follow up that article. In either case, you'll be asked if you want to include the original article in yours. Caution: puts you in whatever text editor is your default.

N Goes to the next subscribed newsgroup with unread articles.

P Goes to the previous subscribed newsgroup with unread

articles.

G news.group Goes to a specific newsgroup. Can be used to subscribe to

new newsgroups. Hitting G brings up a sub-menu:

u Goes to the group and shows only un-read

articles.

a Goes to the group and shows all articles,

even ones you've already read.

s Will show you only articles with a specific

subject.

n Will show you only articles from a specific

person.

M Mails a copy of the current article to somebody. You'll be asked for the recipient's e-mail address and whether you want to add any comments to the article before sending it off. As with F, puts you in the default editor.

:post Post an article. You'll be asked for the name of the group.

Q Quit, or exit, nn.

U Un-subscribe from the current newsgroup.

R Responds to an article via e-mail.

space Hitting the space bar brings up the next page of articles.

X If you have selected articles, this will show them to you and then take you to the next subscribed newsgroup with unread articles. If you don't have any selected articles, it marks all articles as read and takes you to the next unread subscribed newsgroup.

=word Finds and marks all articles in the newsgroup with a specific word in the "subject:" line, for example:

=modem

Z Shows you selected articles immediately and then returns you to the current newsgroup.

? Brings up a help screen.

< Goes to the previous page in the newsgroup.

> Goes to the next page in the newsgroup.

$ Goes to the last page in an article.

^ Goes to the first page in an article.

3.4 USING rn

Some folks prefer this older newsreader.

If you type

rn news.announce.newusers

at your host system's command line, you'll see something like this:

******** 21 unread articles in news.announce.newusers-read now? [ynq]

If you hit your Y key, the first article will appear on your screen. If you want to see what articles are available first, though, hit your computer's = key and you'll get something like this:

The first thing to understand about Usenet is that it is widely misunderstood. Every day on Usenet, the "blind men and the elephant" phenomenon is evident, in spades. In my opinion, more flame wars arise because of a lack of understanding of the nature of Usenet than from any other source. And consider that such flame wars arise, of necessity, among people who are on Usenet. Imagine, then, how poorly understood Usenet must be by those outside!

-MORE-(7%)

This time, the header looks much more like the gobbledygook you get in e-mail messages. To keep reading, hit your space bar. If you hit your n key (lower case), you'll go to the next message in the numerical order. To escape rn, just keep hitting your q key (in lower case), until you get back to the command line. Now let's set up your reading list. Because rn uses the same .newsrc file as nn, you can use one of the search-and-replace methods described above. Or you can do this: Type

rn

and hit enter. When the first newsgroup comes up on your screen, hit your u key (in lower case). Hit it again, and again, and again. Or just keep it pressed down (if your computer starts beeping, let up for a couple of seconds). Eventually, you'll be told you're at the end of the newsgroups, and asked what you want to do next. Here's where you begin entering newsgroups. Type

g newsgroup

(for example, g comp.sys.mac.announce) and hit enter. You'll be asked if you want to "subscribe." Hit your y key. Then type

g next newsgroup

(for example, g comp.announce.newusers) and hit enter. Repeat until done. This process will also set up your reading list for nn, if you prefer that newsreader. But how do you know which newsgroups to subscribe? Typing a lowercase l and then hitting enter will show you a list of all available newsgroups. Again, since there could be more than 2,000 newsgroups on your system, this might not be something you want to do. Fortunately, you can search for groups with particular words in their names, using the l command. Typing

l mac

followed by enter, will bring up a list of newsgroups with those letters in them (and as in nn, you will also see groups dealing with emacs and the like, in addition to groups related to Macintosh computers). Because of the vast amount of messages transmitted over Usenet, most systems carry messages for only a few days or weeks. So if there's a message you want to keep, you should either turn on your computer's screen capture or save it to a file which you can later download). To save a message as a file in rn, type

s filename

where filename is what you want to call the file. Hit enter. You'll be asked if you want to save it in "mailbox format." In most cases, you can answer with an n (which will strip off the header). The message will now be saved to a file in your News directory (which you can access by typing cd News and then hitting enter). Also, some newsgroups fill up particularly quickly - go away for a couple of days and you'll come back to find hundreds of articles! One way to deal with that is to mark them as "read" so that they no longer appear on your screen. In nn, hit a capital J; in rn, a small c.

3.5 rn COMMANDS

Different commands are available to you in rn depending on whether you are already in a newsgroup or reading a specific article. At any point, typing a lowercase h will bring up a list of available commands and some terse instructions for using them. Here are some of them:

After you've just called up rn, or within a newsgroup:

c Marks every article in a newsgroup as read (or "caught up") so that you don't have to see them again. The system will ask you if you are sure. Can be done either when asked if you want to read a particular newsgroup or once in the newsgroup.

g Goes to a newsgroup, in this form:

g news.group

Use this both for going to groups to which you're already

subscribed and subscribing to new groups.

h Provides a list of available commands with terse instructions.

l Gives a list of all available newsgroups.

p Goes to the first previous subscribed newsgroup with un-read articles.

q Quits, or exits, rn if you have not yet gone into a newsgroup. If you are in a newsgroup, it quits that one and brings you to the next subscribed newsgroup.

Only within a newsgroup:

= Gives a list of all available articles in the newsgroup.

m Marks a specific article or series of articles as "un-read" again so that you can come back to them later. Typing

1700m

and hitting enter would mark just that article as un-read. Typing

1700-1800m

and hitting enter would mark all of those articles as un- read.

space Brings up the next page of article listings. If already on the last page, displays the first article in the newsgroup.

u Un-subscribe from the newsgroup.

/text/ Searches through the newsgroup for articles with a specific word or phrase in the "subject:" line, from the current article to the end of the newsgroup. For example,

/EFF/

would bring you to the first article with "EFF" in the "subject:" line.

?text? The same as /text/ except it searches in reverse order from the current article.

Only within a specific article:

e Some newsgroups consist of articles that are binary files, typically programs or graphics images. Hitting e will convert the ASCII characters within such an article into a file you can then download and use or view (assuming you have the proper computer and software). Many times, such files will be split into several articles; just keep calling up the articles and hitting e until done. You'll find the resulting file in your News subdirectory.

C If you post an article and then decide it was a mistake, call

it up on your host system and hit this. The message will soon

begin disappearing on systems around the world.

F Post a public response in the newsgroup to the current

article. Includes a copy of her posting, which you can then

edit down using your host system's text editor.

f The same as above except it does not include a copy of the original message in yours.

m Marks the current article as "un-read" so that you can come

back to it later. You do not have to type the article

number.

Control-N Brings up the first response to the article. If there is no

follow-up article, this returns you to the first unread article

in the newsgroup).

Control-P Goes to the message to which the current article is a reply.

n Goes to the next unread article in the newsgroup.

N Takes you to the next article in the newsgroup even if you've

already read it.

q Quits, or exits, the current article. Leaves you in the current

newsgroup.

R Reply, via e-mail only, to the author of the current article.

Includes a copy of his message in yours.

r The same as above, except it does not include a copy of his

article.

s file Copies the current article to a file in your News directory, where "file" is the name of the file you want to save it to. You'll be asked if you want to use "mailbox" format when saving. If you answer by hitting your N key, most of the header will not be saved.

s|mail user Mails a copy of the article to somebody. For "user" substitute an e-mail address. Does not let you add comments to the message first, however.

space Hitting the space bar shows the next page of the article, or, if at the end, goes to the next un-read article.

3.6 ESSENTIAL NEWSGROUPS

With so much to choose from, everybody will likely have their own unique Usenet reading list. But there are a few newsgroups that are particularly of interest to newcomers. Among them:

news.announce.newusers This group consists of a series of

articles that explain various facets of

Usenet.

news.newusers.questions This is where you can ask questions

(we'll see how in a bit) about how

Usenet works.

news.announce.newsgroups Look here for information about new or proposed newsgroups.

news.answers Contains lists of "Frequently Asked Questions" (FAQs) and their answers from many different newsgroups. Learn how to fight jet lag in the FAQ from rec.travel.air; look up answers to common questions about Microsoft Windows in an FAQ from comp.os.ms-windows; etc.

alt.internet.services Looking for something in particular on

the Internet? Ask here.

alt.infosystems.announce People adding new information services to

the Internet will post details here.

3.7 SPEAKING UP

"Threads" are an integral part of Usenet. When somebody posts a message, often somebody else will respond. Soon, a thread of conversation begins. Following these threads is relatively easy. In nn, related messages are grouped together. In rn, when you're done with a message, you can hit control-N to read the next related message, or followup. As you explore Usenet, it's probably a good idea to read discussions for awhile before you jump in. This way, you can get a feel for the particular newsgroup - each has its own rhythms. Eventually, though, you'll want to speak up. There are two main ways to do this. You join an existing conversation, or you can start a whole new thread. If you want to join a discussion, you have to decide if you want to include portions of the message you are responding to in your message. The reason to do this is so people can see what you're responding to, just in case the original message has disappeared from their system (remember that most Usenet messages have a short life span on the average host system) or they can't find it. If you're using a Unix host system, joining an existing conversation is similar in both nn and rn: hit your F key when done with a given article in the thread. In rn, type a small f if you don't want to include portions of the message you're responding to; an uppercase F if you do. In nn, type a capital F. You'll then be asked if you want to include portions of the original message. And here's where you hit another Unix wall. When you hit your F key, your host system calls up its basic Unix text editor. If you're lucky, that'll be pico, a very easy system. More likely, however, you'll get dumped into emacs (or possibly vi), which you've already met in the chapter on e-mail. The single most important emacs command is

control-x control-c

This means, depress your control key and hit x. Then depress the control key and hit c. Memorize this. In fact, it's so important, it bears repeating:

control-x control-c

These keystrokes are how you get out of emacs. If they work well, you'll be asked if you want to send, edit, abort or list the message you were working on. If they don't work well (say you accidentally hit some other weird key combination that means something special to emacs) and nothing seems to happen, or you just get more weird-looking emacs prompts on the bottom of your screen, try hitting control-g. This should stop whatever emacs was trying to do (you should see the word "quit" on the bottom of your screen), after which you can hit control-x control-c. But if this still doesn't work, remember that you can always disconnect and dial back in! If you have told your newsreader you do want to include portions of the original message in yours, it will automatically put the entire thing at the top of your message. Use the arrow keys to move down to the lines you want to delete and hit control-K, which will delete one line at a time. You can then write your message. Remember that you have to hit enter before your cursor gets to the end of the line, because emacs does not have word wrapping. When done, hit control-X control-C. You'll be asked the question about sending, editing, aborting, etc. Choose one. If you hit Y, your host system will start the process to sending your message across the Net. The nn and rn programs work differently when it comes to posting entirely new messages. In nn, type

:post

and hit enter in any newsgroup. You'll be asked which newsgroup to post a message to. Type in its name and hit enter. Then you'll be asked for "keywords." These are words you'd use to attract somebody scanning a newsgroup. Say you're selling your car. You might type the type of car here. Next comes a "summary" line, which is somewhat similar. Finally, you'll be asked for the message's "distribution." This is where you put how widely you want your message disseminated. Think about this one for a second. If you are selling your car, it makes little sense to send a message about it all over the world. But if you want to talk about the environment, it might make a lot of sense. Each host system has its own set of distribution classifications, but there's generally a local one (just for users of that system), one for the city, state or region it's in, another for the country (for example, usa), one for the continent (for Americans and Canadians, na) and finally, one for the entire world (usually: world). Which one to use? Generally, a couple of seconds' thought will help you decide. If you're selling your car, use your city or regional distribution - people in Australia won't much care and may even get annoyed. If you want to discuss presidential politics, using a USA distribution makes more sense. If you want to talk about events in the Middle East, sending your message to the entire world is perfectly acceptable. Then you can type your message. If you've composed your message offline (generally a good idea if you and emacs don't get along), you can upload it now. You may see a lot of weird looking characters as it uploads into emacs, but those will disappear when you hit control-X and then control-C. Alternately: "save" the message (for example, by hitting m in rn), log out, compose your message offline, log back on and upload your message into a file on your host system. Then call up Usenet, find the article you "saved." Start a reply, and you'll be asked if you want to include a prepared message. Type in the name of the file you just created and hit enter. In rn, you have to wait until you get to the end of a newsgroup to hit F, which will bring up a message-composing system. Alternately, at your host system's command line, you can type

Pnews

and hit enter. You'll be prompted somewhat similarly to the nn system, except that you'll be given a list of possible distributions. If you chose "world," you'll get this message:

This program posts news to thousands of machines throughout the entire civilized world. Your message will cost the net hundreds if not thousands of dollars to send everywhere. Please be sure you know what you are doing.

Are you absolutely sure that you want to do this? [ny]

Don't worry - your message won't really cost the Net untold amounts, although, again, it's a good idea to think for a second whether your message really should go everywhere. If you want to respond to a given post through e-mail, instead of publicly, hit R in nn or r or R in rn. In rn, as with follow-up articles, the upper-case key includes the original message in yours. Most newsgroups are unmoderated, which means that every message you post will eventually wind up on every host system within the geographic region you specified that carries that newsgroup. Some newsgroups, however, are moderated, as you saw earlier with comp.risks. In these groups, messages are shipped to a single location where a moderator, acting much like a magazine editor, decides what actually gets posted. In some cases, groups are moderated like scholarly journals. In other cases, it's to try to cut down on the massive number of messages that might otherwise be posted. You'll notice that many articles in Usenet end with a fancy "signature" that often contains some witty saying, a clever drawing and, almost incidentally, the poster's name and e-mail address. You too can have your own "signature" automatically appended to everything you post. On your own computer, create a signature file. Try to keep it to four lines or less, lest you annoy others on the Net. Then, while connected to your host system, type

cat>.signature

and hit enter (note the period before the s). Upload your signature file into this using your communications software's ASCII upload protocol. When done, hit control-D, the Unix command for closing a file. Now, every time you post a message, this will be appended to it. There are a few caveats to posting. Usenet is no different from a Town Meeting or publication: you're not supposed to break the law, whether that's posting copyrighted material or engaging in illegal activities. It is also not a place to try to sell products (except in certain biz. and for-sale newsgroups).

3.8 CROSS-POSTING

Sometimes, you'll have an issue you think should be discussed in more than one Usenet newsgroup. Rather than posting individual messages in each group, you can post the same message in several groups at once, through a process known as cross-posting. Say you want to start a discussion about the political ramifications of importing rare tropical fish from Brazil. People who read rec.aquaria might have something to say. So might people who read alt.politics.animals and talk.politics.misc. Cross-posting is easy. It also should mean that people on other systems who subscribe to several newsgroups will see your message only once, rather than several times - news-reading software can cancel out the other copies once a person has read the message. When you get ready to post a message (whether through Pnews for rn or the :post command in nn), you'll be asked in which newsgroups. Type the names of the various groups, separated by a comma, but no space, for example:

rec.aquaria,alt.politics.animals,talk.politics.misc

and hit enter. After answering the other questions (geographic distribution, etc.), the message will be posted in the various groups (unless one of the groups is moderated, in which case the message goes to the moderator, who decides whether to make it public). It's considered bad form to post to an excessive number of newsgroups, or inappropriate newsgroups. Probably, you don't really have to post something in 20 different places. And while you may think your particular political issue is vitally important to the fate of the world, chances are the readers of rec.arts.comics will not, or at least not important enough to impose on them. You'll get a lot of nasty e-mail messages demanding you restrict your messages to the "appropriate" newsgroups.
