If you find a list to which you want to subscribe, send an e-mail message to the listed address, which will often be of the form list-request@address.site or majordomo@address.site (majordomo is a common program used to manage mailing lists). If you're writing to a list-request address, chances are good your message will go to a live person. Ask to be put on the list and include your e-mail address, just in case something happens to your header. If it's a majordomo address, you'll typically be told to send a message in this form: subscribe listname where "listname" is the name of the list. As with Usenet, it's generally a good idea to "listen" to the messages for a few days before jumping in. once you want to send a message to everybody on the list, send it to listname@address.site If you want to get off a mailing list, write to the same address you used for subscribing in the first place, only this time, write unsubscribe listname substituting the actual name of the mailing list. 5.2 BITNET As if Usenet and mailing lists were not enough, there are Bitnet "discussion groups" or "lists." Bitnet is an international network linking colleges and universities, but it uses a different set of technical protocols for distributing information from the Internet or Usenet. It offers hundreds of discussion groups, comparable in scope to Usenet newsgroups. As with Internet mailing lists, Bitnet discussions take place in e-mail. However, where mailing lists are often maintained by a person, all Bitnet discussion groups are automated -- you subscribe to them through messages to a "listserver" computer. This is a kind of robot moderator that controls distribution of messages on the list. In many cases, it also maintains indexes and archives of past postings in a given discussion group, which can be handy if you want to get up to speed with a discussion or just search for some information related to it. Many Bitnet discussion groups are now "translated" into Usenet form and carried through Usenet in the bit.listserv hierarchy. In general, it's probably better to read messages through Usenet if you can. It saves some storage space on your host system's hard drives as well as reducing clutter in your mailbox. Think of opening your e-mailbox one day to find 200 messages in it -- 199 of them from a discussion group and one of them a "real" e-mail message that's important to you. Subscribing and canceling subscriptions is done through an e-mail message to the listserver computer. For addressing, all listservers are known as "listserv" (yep) at some Bitnet address. This means you will have to add ".bitnet" to the end of the address, if it's in a form like this: listserv@miamiu. For example, if you have an interest in environmental issues, you might want to subscribe to the Econet discussion group. To subscribe, send an e-mail message to listserv@miamiu.bitnet Some Bitnet listservers are also connected to the Internet, so if you see a listserver address ending in ".edu", you can e-mail the listserver without adding ".bitnet" to the end. Always leave the "subject:" line blank in a message to a listserver. Inside the message, you tell the listserver what you want, with a series of simple commands: subscribe group Your Name To subscribe to a list, where "group" is the list name and "Your Name" is your full name, for example: subscribe econet Henry Fielding unsubscribe group Your Name To discontinue a group, for example: unsubscribe econet Henry Fielding list global This sends you a list of all available Bitnet discussion groups. But be careful -- the list is VERY long! get refcard Sends you a list of other commands you can use with a listserver, such as commands for retrieving past postings from a discussion group. Each of these commands goes on a separate line in your message (and you can use one or all of them). If you want to get a list of all Bitnet discussion groups, send e-mail to listserv@bitnic.educom.edu Leave the "subject:" line blank and use the list global command. When you subscribe to a Bitnet group, there are two important differences from Usenet. First, when you want to post a message for others to read in the discussion group, you send a message to the group name at its Bitnet address. Using Econet as an example, you would mail the message to: econet@miamiu.bitnet Note that this is different from the listserv address you used to subscribe to the group to begin with. Use the listserv address ONLY to subscribe to or unsubscribe from a discussion group. If you use the discussion-group address to try to subscribe or unsubscribe, your message will go out to every other subscriber, many of whom will think unkind thoughts, which they may share with you in an e-mail message). The second difference relates to sending an e-mail message to the author of a particular posting. Usenet newsreaders such as rn and nn let you do this with one key. But if you hit your R key to respond to a discussion- group message, your message will go to the listserver, and from there to everybody else on the list! This can prove embarrassing to you and annoying to others. To make sure your message goes just to the person who wrote the posting, take down his e-mail address from the posting and then compose a brand-new message. Remember, also, that if you see an e-mail address like IZZY@INDYVMS, it's a Bitnet address. Two Bitnet lists will prove helpful for delving further into the network. NEW-LIST tells you the names of new discussion groups. To subscribe, send a message to listserv@ndsuvm1.bitnet: sub NEW-LIST Your Name INFONETS is the place to go when you have questions about Bitnet. It is also first rate for help on questions about all major computer networks and how to reach them. To subscribe, send e-mail to info-nets-request@think.com: sub INFONETS Your Name Both of these lists are also available on Usenet, the former as bit.listserv.new-list; the latter as bit.listserv.infonets (sometimes bit.listserv.info-nets). Chapter 6: TELNET 6.1 MINING THE NET Like any large community, cyberspace has its libraries, places you can go to look up information or take out a good book. Telnet is one of your keys to these libraries. Telnet is a program that lets you use the power of the Internet to connect you to databases, library catalogs, and other information resources around the world. Want to see what the weather's like in Vermont? Check on crop conditions in Azerbaijan? Get more information about somebody whose name you've seen online? Telnet lets you do this, and more. Increasingly, information once available only via telnet is being disseminated by the World-Wide Web (see Chapter 9) -- but it can still be useful to learn your way around telnet. Alas, there's a big "but!'' Unlike the phone system, Internet is not yet universal; not everybody can use all of its services. Almost all colleges and universities on the Internet provide telnet access. So do all of the for-fee public-access systems listed in Chapter 1. But the Free-Net systems do not give you access to every telnet system. And if you are using a public-access UUCP or Usenet site, you will not have access to telnet. The main reason for this is cost. Connecting to the Internet can easily cost $1,000 or more for a leased, high-speed phone line. Some databases and file libraries can be queried by e-mail, however; we'll show you how to do that later on. In the meantime, the rest of this chapter assumes you are connected to a site with at least partial Internet access. Most telnet sites are fairly easy to use and have online help systems. Most also work best (and in some cases, only) with VT100 emulation. Let's dive right in and try one. At your host system's command line, type telnet access.usask.ca and hit enter. That's all you have to do to connect to a telnet site! In this case, you'll be connecting to a service known as Hytelnet, which is a database of computerized library catalogs and other databases available through telnet. You should see something like this: Trying 128.233.3.1 ... Connected to access.usask.ca. Escape character is '^]'. Ultrix UNIX (access.usask.ca) login: Every telnet site has two addresses -- one composed of words that are easier for people to remember; the other a numerical address better suited for computers. The "escape character" is good to remember. When all else fails, depressing your hitting your control key and then the ] key at the same time will disconnect you and return you to your host system. At the login prompt for this particular site, type hytelnet and hit enter. You'll see something like this: Welcome to HYTELNET version 6.2 ................... What is HYTELNET? <WHATIS> . Up/Down arrows MOVE Library catalogs <SITES1> . Left/Right arrows SELECT Other resources <SITES2> . ? for HELP anytime Help files for catalogs <OP000> . Catalog interfaces <SYS000> . m returns here Internet Glossary <GLOSSARY> . q quits Telnet tips <TELNET> . Telnet/TN3270 escape keys <ESCAPE.KEY> . Key-stroke commands <HELP.TXT> . ........................ HYTELNET 6.2 was written by Peter Scott, U of Saskatchewan Libraries, Saskatoon, Sask, Canada. 1992 Unix and VMS software by Earl Fogel, Computing Services, U of S 1992 The first choice, "<WHATIS>" will be highlighted. Use your down and up arrows to move the cursor among the choices. Hit enter when you decide on one. You'll get another menu, which in turn will bring up text files telling you how to connect to sites and giving any special commands or instructions you might need. Hytelnet does have one quirk. To move back to where you started (for example, from a sub-menu to a main menu), hit the left-arrow key on your computer. Play with the system. You might want to turn on your computer's screen- capture, or at the very least, get out a pen and paper. You're bound to run across some interesting telnet services that you'll want to try -- and you'll need their telnet "addresses.'' As you move around Hytelnet, it may seem as if you haven't left your host system -- telnet can work that quickly. Occasionally, when network loads are heavy, however, you will notice a delay between the time you type a command or enter a request and the time the remote service responds. To disconnect from Hytelnet and return to your system, hit your q key and enter. Some telnet computers are set up so that you can only access them through a specific "port." In those cases, you'll always see a number after their name, for example: india.colorado.edu 13. It's important to include that number, because otherwise, you may not get in. In fact, try the above address. Type telnet india.colorado.edu 13 and hit enter. You should see something like this: Trying 128.138.140.44 ... Followed very quickly by this: telnet india.colorado.edu 13 Escape character is '^]'. Sun Jan 17 14:11:41 1994 Connection closed by foreign host. What we want is the middle line, which tells you the exact Mountain Standard Time, as determined by a government-run atomic clock in Boulder, Colo. 6.2 LIBRARY CATALOGS Several hundred libraries around the world, from the Snohomish Public Library in Washington State to the Library of Congress are now available to you through telnet. You can use Hytelnet to find their names, telnet addresses and use instructions. Why would you want to browse a library you can't physically get to? Many libraries share books, so if yours doesn't have what you're looking for, you can tell the librarian where he or she can get it. Or if you live in an area where the libraries are not yet online, you can use telnet to do some basic bibliographic research before you head down to the local branch. There are several different database programs in use by online libraries. Harvard's is one of the easier ones to use, so let's try it. Telnet to hollis.harvard.edu. When you connect, you'll see: ***************** H A R V A R D U N I V E R S I T Y ***************** OFFICE FOR INFORMATION TECHNOLOGY *** *** *** *** VE *** RI *** *** *** *** HOLLIS (Harvard OnLine LIbrary System) ***** ***** **** TAS **** HUBS (Harvard University Basic Services) *** *** ***** IU (Information Utility) *** CMS (VM/CMS Timesharing Service) ** HOLLIS IS AVAILABLE WITHOUT ACCESS RESTRICTIONS ** Access to other applications is limited to individuals who have been granted specific permission by an authorized person. To select one of the applications above, type its name on the command line followed by your user ID, and press RETURN. ** HOLLIS DOES NOT REQUIRE A USERID ** EXAMPLES: HOLLIS (press RETURN) or HUBS userid (press RETURN) ===> Type hollis and hit enter. You'll see several screens flash by quickly until finally the system stops and you'll get this: WELCOME TO HOLLIS (Harvard OnLine Library Information System) To begin, type one of the 2-character database codes listed below: HU Union Catalog of the Harvard libraries OW Catalog of Older Widener materials LG Guide to Harvard Libraries and Computing Resources AI Expanded Academic Index (selective 1987-1988, full 1989- ) LR Legal Resource Index (1980- ) PA PAIS International (1985- ) To change databases from any place in HOLLIS, type CHOOSE followed by a 2-character database code, as in: CHOOSE HU For general help in using HOLLIS, type HELP. For HOLLIS news, type HELP NEWS. For HOLLIS hours of operation, type HELP HOURS. ALWAYS PRESS THE ENTER OR RETURN KEY AFTER TYPING YOUR COMMAND The first thing to notice is the name of the system: Hollis. Librarians around the world seem to be inordinately found of cutesy, anthropomorphized acronyms for their machines (not far from Harvard, the librarians at Brandeis University came up with Library On-Line User Information Service, or Louis; MIT has Barton). If you want to do some general browsing, probably the best bet on the Harvard system is to chose HU, which gets you access to their main holdings, including those of its medical libraries. Chose that, and you'll see this: THE HARVARD UNIVERSITY LIBRARY UNION CATALOG To begin a search, select a search option from the list below and type its code on the command line.

Most library systems give you a way to log off and return to your host system. On Hollis, hit escape followed by xx One particularly interesting system is the one run by the Colorado Alliance of Research Libraries, which maintains databases for libraries throughout Colorado, the West and even in Boston. Telnet pac.carl.org. Follow the simple log-in instructions. When you get a menu, type 72 (even though that is not listed), which takes you to the Pikes Peak Library District, which serves the city of Colorado Springs. Several years ago, its librarians realized they could use their database program not just for books but for cataloging city records and community information, as well. Today, if you want to look up municipal ordinances or city records, you only have to type in the word you're looking for and you'll get back cites of the relevant laws or decisions. Carl will also connect you to the University of Hawaii library, which, like the one in Colorado Springs, has more than just bibliographic material online. One of its features is an online Hawaiian almanac that can tell you everything you ever wanted to know about Hawaiians, including the number injured in boogie-board accidents each year (seven). 6.3 SOME INTERESTING TELNET SITES AGRICULTURE PENPages, run by Pennsylvania State University's College of Agricultural Sciences, provides weekly world weather and crop reports from the U.S. Department of Agriculture. These reports detail everything from the effect of the weather on palm trees in Malaysia to the state of the Ukrainian wheat crop. Reports from Pennsylvania country extension officers offer tips for improving farm life. One database lists Pennsylvania hay distributors by county -- and rates the quality of their hay! The service lets you search for information two different ways. A menu system gives you quick access to reports that change frequently, such as the weekly crop/weather reports. An index system lets you search through several thousand online documents by keyword. At the main menu, you can either browse through an online manual or chose "PENPages,'' which puts you into the agriculture system. Telnet: psupen.psu.edu User name: Your 2-letter state code or WORLD California State University's Advanced Technology Information Network provides similar information as PENPages, only focusing on California crops. It also maintains lists of upcoming California trade shows and carries updates on biotechnology. Telnet: caticsuf.cati.csufresno.edu Log in: public You will then be asked to register and will be given a user name and password. Hit "a'' at the main menu for agricultural information. Hit "d'' to call up a menu that includes a biweekly biotechnology report. AIDS The University of Miami maintains a database of AIDS health providers in southern Florida. Telnet: callcat.med.miami.edu Log in: library At the main menu, select P (for "AIDS providers" and you'll be able to search for doctors, hospitals and other providers that care for patients with AIDS. You can also search by speciality. See also under Conversation and Health. AMATEUR RADIO The National Ham Radio Call-Sign Callbook lets you search for American amateur operators by callsign, city, last name or Zip code. A successful search will give you the ham's name, address, callsign, age, type of license and when he or she got it. Telnet: callsign.cs.buffalo.edu 2000 or ham.njit.edu 2000. When you connect, you tell the system how you want to search and what you're looking for. For example, if you want to search for hams by city, you would type city name of city and hit enter (for example: city Kankakee). Other search choices are "call" (after which you would type a ham's name), "name," and "zip" (which you would follow with a Zip code). Be careful when searching for hams in a large city; there doesn't seem to be anyway to shut off the list once it starts except by using control-]. Otherwise, when done, type quit and hit enter to disconnect. ANIMALS See under Health. CALCULATORS Hewlett-Packard maintains a free service on which you can seek advice about their line of calculators. Telnet: hpcvbbs.cv.hp.com No log-in is needed. CHEMISTRY The Electronic Periodic Table of the Elements draws the table on your screen and then lets you look up various properties of individual elements. Telnet: camms2.caos.kun.nl No password needed. CONVERSATION Communications Canada, a Canadian government agency is developing Conversational Hypertext Access Technology (CHAT) is a system being developed by Communications Canada to provide easy database access to people with little or no computer experience, using what are known as hypertext links. Instead of cryptic computer commands, users type questions in English. Telnet: debra.doc.ca Log in: chat You chose one of the three databases now online, one on AIDS, and then ask questions in English. Ask the AIDS database, "When was AIDS first discovered?'' and it answers: "The first case of AIDS in North America was diagnosed in 1979. Before that, it existed in Africa, probably beginning in the 1950's. AIDS was discovered in North America when a number of young men with a history of homosexuality developed a rare type of cancer called Kaposi's sarcoma.'' Sometimes, you do have to rephrase your question. For example, when asked "What is the link between AIDS and drug use?'' the computer responds: "I know two things about drugs: the drugs that are used to treat people with AIDS, and the risks that drug users have in getting AIDS. Please ask about treatments or drug users.'' COPYRIGHT LAW See under Congress. CURRENT EVENTS Every year, the CIA publishes a Fact Book that is essentially an almanac of all the world's countries and international organizations, including such information as major products, type of government and names of its leaders. It's available for searching through the University of Maryland Info Database. Telnet: info.umd.edu Chose a terminal type and hit enter (or just hit enter if you are using VT100). At the main menu, choose the number next to "Educational Resources." Then select the number next to "International," followed by "Factbook." You can then search by country or agency. This site also maintains copies of the U.S. budget, documents related to the North American Free Trade Agreement and other government initiatives. At the "Educational Resources" menu, select the number next to "United States" and then the one next to "Government." The Access Legislative Information Service lets you browse through and look up bills before the Hawaiian legislature. Telnet: access.uhcc.hawaii.edu ENVIRONMENT Envirolink is a large database and conference system about the environment, based in Pittsburgh. Telnet: envirolink.org Log on: gopher The U.S. Environmental Protection Agency maintains online databases of materials related to hazardous waste, the Clean Lakes program and cleanup efforts in New England. The agency plans to eventually include cleanup work in other regions, as well. The database is actually a computerized card catalog of EPA documents -- you can look the documents up, but you'll still have to visit your regional EPA office to see them. Telnet: epaibm.rtpnc.epa.gov No password or user name is needed. At the main menu, type public and hit enter (there are other listed choices, but they are only for use by EPA employees). You'll then see a one-line menu. Type ols and hit enter, and you'll see something like this: NET-106 Logon to TSO04 in progress. DATABASES: N NATIONAL CATALOG CH CHEMICAL COLL.

The University of Michigan maintains a database of newspaper and magazine articles related to the environment, with the emphasis on Michigan, dating back to 1980. Telnet: hermes.merit.edu Host: mirlyn Log in: meem GEOGRAPHY The University of Michigan Geographic Name Server can provide basic information, such as population, latitude and longitude of U.S. cities and many mountains, rivers and other geographic features. Telnet: martini.eecs.umich.edu 3000 No password or user name is needed. Type in the name of a city, a Zip code or a geographic feature and hit enter. The system doesn't like names with abbreviations in them (for example, Mt. McKinley), so spell them out (for example, Mount McKinley). By typing in a town's name or zip code, you can find out a community's county, Zip code and longitude and latitude. Not all geographic features are yet included in the database. GOVERNMENT The Library of Congress Information Service lets you search current and past legislation (dating to 1982). Telnet: locis.loc.gov Password: none needed. When you connect, you'll get a main menu that lets you select from several databases, including the Library of Congress card catalog (with book entries dating to 1978) and a database of information on copyright laws. For the congressional database, select the number next to its entry and hit enter. You'll then be asked to choose which legislative year to search. After that, a menu similar to this will come up: ***C103- THE LEGISLATIVE INFORMATION FILE FOR THE 103RD CONGRESS, which was updated on 05/10/93 and contains 4,044 records, is now available for your search. CURRENCY: All information is NOT current through the above date, which is machine generated when ANY information is added to the file.

Also see under Weather in the FTP list for information on downloading satellite and radar weather images. 6.4 TELNET BULLETIN-BOARD SYSTEMS You might think that Usenet, with its hundreds of newsgroups, would be enough to satisfy the most dedicated of online communicators. But there are a number of "bulletin-board" and other systems that provide even more conferences or other services, many not found directly on the Net. Some are free; others charge for access. They include: Cimarron. Run by the Instituto Technical in Monterey, Mexico, this system has Spanish conferences, but English commands, as you can see from this menu of available conferences: List of Boards Name Title General Board general Dudas Dudas de Cimarron Comentarios Comentarios al SYSOP Musica Para los afinados........ Libros El sano arte de leer..... Sistemas Sistemas Operativos en General. Virus Su peor enemigo...... Cultural Espacio Cultural de Cimarron NeXT El Mundo de NeXT Ciencias Solo apto para Nerds. Inspiracion Para los Romanticos e Inspirados. Deportes Discusiones Deportivas To be able to write messages and gain access to files, you have to leave a note to SYSOP with your name, address, occupation and phone number. To do this, at any prompt, hit your M key and then enter, which will bring up the mail system. Hitting H brings up a list of commands and how to use them. Telnet: bugs.mty.itesm.mx (8 p.m. to 10 a.m., Eastern time, only). At the "login:" prompt, type bbs and hit enter. Cleveland Free-Net. The first of a series of Free-Nets, this represents an ambitious attempt to bring the Net to the public. Originally an in- hospital help network, it is now sponsored by Case Western Reserve University, the city of Cleveland, the state of Ohio and IBM. It uses simple menus, similar to those found on CompuServe, but organized like a city: <<< CLEVELAND FREE-NET DIRECTORY >>> 1 The Administration Building 2 The Post Office 3 Public Square 4 The Courthouse & Government Center 5 The Arts Building 6 Science and Technology Center 7 The Medical Arts Building 8 The Schoolhouse (Academy One) 9 The Community Center & Recreation Area 10 The Business and Industrial Park 11 The Library 12 University Circle 13 The Teleport 14 The Communications Center 15 NPTN/USA TODAY HEADLINE NEWS ------------------------------------------------ h=Help, x=Exit Free-Net, "go help"=extended help Your Choice ==> The system has a vast and growing collection of public documents, from copies of U.S. and Ohio Supreme Court decisions to the Magna Carta and the U.S. Constitution. It links residents to various government agencies and has daily stories from USA Today. Beyond Usenet (found in the Teleport area), it has a large collection of local conferences on everything from pets to politics. And yes, it's free! Telnet: freenet-in-a.cwru.edu or freenet-in-b.cwru.edu or freenet-in-c.cwru.edu When you connect to Free-Net, you can look around the system. However, if you want to be able to post messages in its conferences or use e-mail, you will have to apply in writing for an account. Information on this is available when you connect. DUBBS. This is a bulletin-board system in Delft in the Netherlands. The conferences and files are mostly in Dutch, but the help files and the system commands themselves are in English. Telnet: tudrwa.tudelft.nl ISCA BBS. Run by the Iowa Student Computer Association, it has more than 100 conferences, including several in foreign languages. After you register, hit K for a list of available conferences and then J to join a particular conference (you have to type in the name of the conference, not the number next to it). Hitting H brings up information about commands. Telnet bbs.isca.uiowa.edu At the "login:" prompt, type bbs and hit enter. Youngstown Free-Net. The people who created Cleveland Free-Net sell their software for $1 to anybody willing to set up a similar system. A number of cities now have their own Free-Nets, including Youngstown, Ohio. Telnet: yfn.ysu.edu At the "login:" prompt, type visitor and hit enter. 6.5 PUTTING THE FINGER ON SOMEONE Finger is a handy little program which lets you find out more about people on the Net -- and lets you tell others on the Net more about yourself. Finger uses the same concept as telnet or ftp. But it works with only one file, called .plan (yes, with a period in front). This is a text file an Internet user creates with a text editor in his home directory. You can put your phone number in there, tell a little bit about yourself, or write almost anything at all. To finger somebody else's .plan file, type this at the command line: finger email-address where email-address is the person's e-mail address. If that person's site allows incoming finger requests (not all do), You'll get back a display that shows the last time the person was online, whether they've gotten any new mail since that time and what, if anything, is in their .plan file. Some people and institutions have come up with creative uses for these .plan files, letting you do everything from checking the weather in Massachusetts to getting the latest baseball standings. Try fingering these e-mail addresses: weather@cirrus.mit.edu Latest National Weather Service weather forecasts for regions in Massachusetts. quake@geophys.washington.edu Locations and magnitudes of recent earthquakes around the world. jtchern@ocf.berkeley.edu Current major-league baseball standings and results of the previous day's games. nasanews@space.mit.edu The day's events at NASA. coke@cs.cmu.edu See how many cans of each type of soda are left in a particular soda machine in the computer-science department of Carnegie-Mellon University. 6.6 FINDING SOMEONE ON THE NET So you have a friend and you want to find out if he has an Internet account to which you can write? The quickest way may be to just pick up the phone, call him and ask him. Although there are a variety of "white pages" services available on the Internet, they are far from complete -- college students, users of commercial services such as CompuServe and many Internet public-access sites, and many others simply won't be listed. Major e-mail providers are working on a universal directory system, but that could be some time away. In the meantime, a couple of "white pages" services might give you some leads, or even just entertain you as you look up famous people or long- lost acquaintances. The whois directory provides names, e-mail and postal mail address and often phone numbers for people listed in it. To use it, telnet to internic.net No log-on is needed. The quickest way to use it is to type whois name at the prompt, where "name" is the last name or organization name you're looking for. If there's a match, you'll get back an e-mail listing. Another service worth trying, especially since it seems to give beginners fewer problems, is the Knowbot Information Service reachable by telnet at info.cnri.reston.va.us 185 Again, no log-on is needed. This service actually searches through a variety of other "white pages" systems, including the user directory for MCIMail. To look for somebody, type query name where "name" is the last name of the person you're looking for. You can get details of other commands by hitting a question mark at the prompt. You can also use the knowbot system by e-mail. Start a message to netaddress@info.cnri.reston.va.us You can leave the "subject:" line blank. As your message, type query name for the simplest type of search. If you want details on more complex searches, add another line: man Another way to search is via the Usenet name server. This is a system at MIT that keeps track of the e-mail addresses of everybody who posts a Usenet message that appears at MIT. It works by e-mail. Send a message to mail-server@rtfm.mit.edu Leave the "subject:" line blank. As your message, write send usenet-addresses/lastname where "lastname" is the last name of the person you're looking for. The system will write back with any matches and the associated addresses. 6.7 WHEN THINGS GO WRONG * Nothing happens when you try to connect to a telnet site. The site could be down for maintenance or problems. * You get a "host unavailable" message. The telnet site is down for some reason. Try again later.
