There's Gold in them thar Networks! or Searching for Treasure in all the Wrong Places

Status of this Memo

This RFC provides information for the Internet community. It does not specify an Internet standard. Distribution of this memo is unlimited.

Abstract

A wealth of information exists on the network. In fact, there is so much information that you could spend your entire life browsing. This paper will present some of the "gold nuggets" of information and file repositories on the network that could be useful.

The ultimate goal is to make the route to these sources of information invisible to you. At present, this is not easy to do. I will explain some of the techniques that can be used to make these nuggets easier to pick up so that we all can be richer.

RFC 1402 Searching for Treasure January 1993

1.0 Introduction

This paper is a list of the essential things, in my view, that a people who are responsible for providing network information should have in their hands as reference material. One of the basic problems with information is making it easily available to those who need the data. Libraries have been performing a cataloging function for many centuries. Information flow is now being provided so fast that it is difficult to keep up with it, even partially. Computer networks have only added to the problem by opening up access to even more information.

Attempting to make this wealth of information available to those who would find it useful poses some problems.

First, we need to know of its existence. To that end, this paper provides an index to the vast realm of network information. Most of the documents listed here are POINTERS to the final information.

Second, even if you know of a document's existence, you may not know if it is important or relevant. Few of us are knowledgeable in more than a limited area. We need to rely on others to make us aware of the importance of databases in a specific discipline. Librarians can be of great assistance here. They are familiar with the research databases that individuals search in law, mathematics, and many other fields.

Finally, once existence and importance are known, the information needs to be indexed so that researchers can find it. This is the most difficult task to accomplish. Information available on the network is rarely static. It is always moving, growing, changing, and dying. Computers should be able to assist us in managing this ever-changing environment. Right now, we have to catalog the information as it passes through the network. In my case, I generally save it in a file somewhere and spend far too much time trying to retrieve it again when I need it.

1.5 Access to the Internet

A frequently asked question concerns how the average mortal gets access to the Internet. The most common way is via electronic mail. Using e-mail, it is possible to communicate with anyone on the Internet and on any other networks as well, and there are many "gateways" to the Internet from other networks and systems. For instance using CompuServe, a large commercial electronic information and communication service, you can send e-mail to and from individuals on the Internet.

Martin [Page 2]

RFC 1402 Searching for Treasure January 1993

A direct connection to the Internet provides some additional capabilities that e-mail cannot. One of these is the ability to establish a connection to a remote computer connected to the Internet from your own personal computer or from one connected to the Internet. The program that establishes this connection is called Telnet. Many universities and large research companies have Internet connections. They pay rather large fees to have these high speed (more than one million bits per second) connections. If you are associated with a large university or company you already may have access or can gain access to the Internet using one of their computers.

A direct connection to the Internet also allows you to transfer a file from a remote computer. This program is referred to as FTP (file transfer protocol). Section 4.0 covers the many places that have files and programs available using FTP.

The following information was taken from a Frequently Asked Question posting by Aydin Edguer to the alt.bbs newsgroup.

If you do not have access to a service connected to Internet, you can get access for a fee. The following companies provide Internet access to individuals or companies at various rates depending on the time of access, speed of access desired, and several other factors.

The first method to gain access to the Internet is by getting an account on a public access bulletin board system that is connected to the Internet. There are a growing number of such systems available. For information on some of these systems, send electronic mail to:

info@world.std.com info@netcom.com info@concert.net info@panix.com info@holonet.net info@msen.com info@csn.org sysadmin@ids.com

Any of these systems is open to the public for a monthly access fee.

A second method to gain access to the Internet is by getting an account with a network service provider who offers a dial-in service. See the "How do I get connected to the Internet?" section for more information.

Martin [Page 3]

RFC 1402 Searching for Treasure January 1993

How do I get connected to the Internet?

Traditionally, connections to the Internet were dedicated connections. This is still the most common type of connection. Monthly costs for the connection range anywhere from $250 per month [plus line charges] for a dialup 9600-bps connection to $4,000 [plus line charges] for a T1 [1.44-Mbps] connection. There is also an initial one-time startup fee of anywhere from $100 to $8,000 [plus equipment charges].

Some service providers also are offering part-time dialup connections. Customers share a set of phone lines and dialup when needed. This is usually less expensive than dedicated dialup connections for customers who need a connection less than 80 hours per month. Monthly costs range from $40-100 per month [plus line charges] plus an hourly charge of $2-4.

Some service providers have begun to offer a new dial-in service. The name for dial-in service varies from vendor to vendor. The dial-in service is usually provided as a way for Internet-connected users to connect back to their home sites from remote locations. But most service providers do not limit their service to this audience, it is open to people not already on the Internet. The dial-in service provides either a terminal server connection [with password] or an account on the service provider's equipment [with password] which permits you to use Telnet to connect to other sites on the Internet. This service differs from the normal dialup IP services because it does not require the user to run any IP software like PPP (Point-to-Point protocol) or SLIP (serial line IP). The cost for this service usually range from $35 to $250 per month [plus line charges]. There is also an initial $35 to $500 connection fee [plus equipment charges].

The following is a list of known Internet service providers, along with the services they offer, an e-mail address to contact for more information, a phone number to contact for more information, or an FTP archive for more information.

Please note, although this is a Frequently asked Question, this newsgroup, alt.bbs.internet, is NOT for the discussion of how to get connected to the Internet. This is the correct newsgroup to discuss your bulletin board system and what it offers once you are connected to the Internet.

The above excerpt is from a frequently asked questions Usenet posting to alt.bbs.internet and crossposted to news.answers. The news.answers newsgroup is a very good group to subscribe to read the frequently asked questions sent to many newsgroups. See 12.6 Usenet entry in the Glossary for more information on newsgroups.

Martin [Page 6]

RFC 1402 Searching for Treasure January 1993

Further investigation in the above groups yields a great deal of information about techniques and rates to access the Internet. Of course one common question is about getting free access. As mentioned before if you are associated with a university, a large company, or research group you may very well have access via one of their computers. If you are a student or faculty member and are away from your local campus, you may be able to get a guest account from the local university.

Some campuswide information systems may give limited access to the network in a read-only mode. Also some communities (such as Cleveland) operate a FREENET which enables you to read newsgroups and if you register send mail at no charge. See section 8.0 for more information.

For example, you can Telnet to Holonet below to get an idea of how it works. This is not an endorsement of this system but it does give you a good idea how this type of access to an Internet BBS works.

2.16 World Wide Webb

The WWW project merges the techniques of information retrieval and hypertext to make an easy but powerful global information system.

The project is based on the philosophy that academic information should be freely available to anyone. Its aim is to permit information sharing within internationally dispersed teams and dissemination of information by support groups. Originally aimed at the High Energy Physics community, it has spread to other areas and attracted much interest in user support, resource discovery, and collaborative work areas.

Reader View

The WWW world consists of documents and links. Indexes are special documents which, rather than being read, can be searched. The result of such a search is another ("virtual") document containing links to the documents found. A simple protocol ("HTTP") is used to allow a browser program to request a keyword search by a remote information server.

The web contains documents in many formats. Those hypertext documents (real or virtual) contain links to other documents or places within documents. All documents, whether real, virtual or indexes, look similar to the reader and are contained within the same addressing scheme.

To follow a link, you either click with a mouse or type in a number. To search an index, give keywords or other search criteria. These are the only operations necessary to access the entire world of data.

You can try the simple line mode browser by Telnetting to info.cern.ch (no user or password) From UK JANET, use the gateway. You also can find out more about WWW in this way. This is the least sophisticated browser; remember that the window-oriented ones are much smarter.

It is much more efficient to install a browser on your own machine. The line mode browser is currently available in source form by anonymous FTP from node: info.cern.ch [currently 128.141.201.74] as:

/pub/www/src/WWWLineMode_v.vv.tar.Z.

(v.vv is the version number - take the latest.)

4.0 The Mother Lode of Anonymous FTP Sites

Throughout this document, sites are listed for specific documents. Most are only indexes to more information. A big problem is

Martin [Page 14]

RFC 1402 Searching for Treasure January 1993

searching through all this information to find what you want. One of the best search methods is Archie, described below.

Several sites contain large repositories of files and other sites that are the source for specific programs such as Kermit, the public domain file transfer program.

4.05 archie

One of the best ways of searching for a program available via anonymous FTP is with archie (Archive Server Listing Service), several of these servers scattered throughout the world. The fastest one I have found is the Advanced Network & Services, Inc. located in the United States.

Archie goes to every site that offers anonymous FTP files, collects the file structure from that site, and places it in a database it can search.

A real-life example. I was reading an article about Windows in the July 1992 issue of PC World, and it mentioned a shareware program called ZiPaper on page 212. The name of the program is zipapr.zip. I can use Archie to locate this program.

Source:

telnet archie.ans.net

login as archie

At the archie prompt type

prog zipapr.zip

The response is

Host wuarchive.wustl.edu (128.252.135.2) Last updated 17:22 13 July 1992

Location: /mirrors3/archive.umich.edu/msdos/mswindows/desktop FILE rw-rw-r-- 41984 Jan 30 1991 zipapr.zip

This tells you the file is available via anonymous FTP to wuarchive.wustl.edu in the directory mirrors3/archive.umich.edu/msdos/mswindows/desktop and the file is zipapr.zip.

4.1 Washington University (anonymous FTP)

Washington University represents perhaps one of the most popular sites for software on the network. The Mirrors directory contains a copy of all of the wsmr-simtel20.army.mil files. Wsmr-simtel20- army.mil is the originator and keeper of major amounts of public domain software. Their site, however, is often overloaded and difficult to connect to.

You will find enough software in the Mirrors directory to keep you busy for the rest of your life. The MS-DOS and Macintosh subdirectories contain files for those specific machines.

7.0 Campuswide Information Systems - CWISes

The information in this section is intended primarily for those who are providing access methods from their own computing environments. Although standards have been proposed, there are no "packages" that give you access to all of the information presented here. What The Ohio State University and several other universities have done is provide a menu to the user that accesses these services and databases behind the scenes. In fact, I had to refer to the shell scripts to look up the network addresses of these machines, because I rely on the menu for access as well.

As the name implies, information systems provide access to information the user knowing exactly how to get to it. In this way, the network is invisible to end users. All they need to know is what they want, not the command structure needed to actually get the information.

At present, the menu system seems to be the easiest way in In the background is a knowbot, a program that knows how to go out and locate services on the network using a keyword search.

You can connect to the following sites for a demonstration of their capabilities.

Many CWIS systems are converting to Gopher (see section 8.96). Hytelnet (see section 2.15) also has complete listings of CWIS systems.

9.0 WHOIS - E-mail white pages

WHOIS is a program available on many workstation/mini/mainframe computers that can connect to another computer. By supplying a persons name, it will respond with information it has on the person. A similar program called finger does the same type of thing, except it only supplies information on individuals with an account on that specific computer. A WHOIS database generally is contains information on most of the individuals at a university, not just on the machine you connect to.

In a larger sense WHOIS is a technique for finding a person's e-mail address. There is no master list of e-mail addresses on the network. Standards have been established for supplying e-mail addresses, but it will take some time for it to be globally implemented. In the meantime, the easiest way to find out is to call and ask!

I can just hear the gasps of horror, using the phone for anything but talking to your mom, sacrilege. There are, of course, many ways of finding a person's e-mail address. But what you don't know is if the person even reads his/her e-mail, and in the case of multiple e-mail addresses, which one is correct. A simple phone call the first time will answer those unknowns quickly.

The following documents and resources will assist in finding a person's e-mail address.

9.03 College E-mail Address

9.07 Inter-Network Guide

When mailing from one network to another you need to know what address to use to access the gateway. For instance, if you want to send a message from the Internet to someone on CompuServe, you address it to 12345.1234@compuserve.com, where the 12345.1234 is the person's CompuServe ID in the form 12345,1234.

12.0 Glossary

I use some terms here that may not be familiar to all. The following is a brief explanation.

12.1 BITNET:

A network of mainframes or minicomputers. BITNET connects many universities and colleges. It provides e-mail and file transfer capabilities, but does not have the ability to do remote login (Telnet session capability).

12.2 Internet:

A very large network that connects just about any types of computers. It supports e-mail, file transfer (FTP), and remote login (Telnet).

12.3 Anonymous FTP:

The ability to transfer a file from a remote computer connected to the Internet without having an account on the remote computer. The program that performs the file transfer is normal FTP. To connect to a remote computer offering anonymous FTP, you can use the following commands from a computer connected to the Internet.

Martin [Page 37]

RFC 1402 Searching for Treasure January 1993

FTP Internet computer name When prompted for a userid, type anonymous When prompted for a password, type your e-mail address To get a listing of files type dir To change directory, type cd directory name To get a file, type get filename To get a binary file, type binary then get filename To end session, type quit

Example: FTP pilot.njin.net Username: anonymous Password: yourname@computer.edu cd pub/ftp-list get ftp.list quit

12.4 Telnet:

The ability to establish a connection to a remote computer connected to the Internet network. Two types of programs are used to do this. One, usually called Telnet, establishes a VT100-type terminal emulation to the remote computer. The second, TN3270, establishes a full-screen IBM 3270-type terminal connection.

12.5 Listserv:

A program available on many BITNET connected computers that can act as a mail forwarding system and as a file repository. BITNET is another network that links many colleges and universities It does not normally link to military or government institutions as does the Internet. To subscribe to a listserv, you usually send mail to the machine that has the mailing list with the command to subscribe. As an example, to subscribe to a list for discussion of topics pertinent to mechanical engineering, send e-mail to listserv@utarlvml with a message containing the one-line command to subscribe:

SUB MECH-1 John Doe (Where John Doe would be your full name)

12.6 Usenet/Read News

Newsgroups are like public bulletin boards that you can post and read messages from other individuals world wide. More than 1500 groups cover topics ranging from arts and recreation to more research oriented topics such as physics, philosohy, microbiology and many many others. Normally you gain access through a computer that has lots of disk space and is connected directly to the

Martin [Page 38]

RFC 1402 Searching for Treasure January 1993

Internet. You can read many of the newgroups from the Cleveland Freenet (section 8.1) or from commercial providors of Intenet access; for example, Holonet (section 1.7).

The information provided in the previous sections has been put together from multiple sources acquired from the network. Much of it came from reading newsgroups and trying things out to see how they worked. The information is as accurate as I have been able to determine, as of July 17, 1992.

I used a DEC5500 system running Ultrix to check most of these sources. Most of the information is oriented toward Internet, since it has remote login (Telnet) and file transfer (FTP).
