RFC 1739           Primer on Internet & TCP/IP Tools       December 1994


   Archie servers may be accessed using TELNET.  When TELNETing to an
   Archie site, login as "archie" (you MUST use lower case); just hit
   <ENTER> if a password is requested.

   Once connected, the "help" command assists users in obtaining more
   information about using Archie.  Two more useful Archie commands are
   "prog", used to search for files in the database, and "whatis", which
   searches for keywords in the program descriptions.

   In the accompanying dialogue, the "set maxhits" command is used to
   limit the number of responses to any following "prog" commands; if
   this is not done, the user may get an enormous amount of information!

   In this example, the user issues a request to find entries related to
   "mpeg", ISO's Moving Pictures Experts Group video compression
   standard.  Armed with this information, a user can use anonymous FTP
   to examine these directories and files.

   The next request is for files with "security" as a keyword
   descriptor.  These responses can be used for subsequent "prog"
   commands.

   Exit archie using the "exit" command.  At this point, TELNET closes
   the connection and control returns to the local host.

   Additional information about Archie can be obtained by sending e-mail
   to Bunyip Information Systems ([e-mail]).  Client
   software is not required to use Archie, but can make life a little
   easier; some such software can be downloaded using anonymous FTP from
   the "/pub/archie/" directory at host "ftp.cs.widener.edu" or in
   "/pub/archie/clients/" at "ftp.sura.net".  Most shareware and
   commercial Archie clients hide the complexity described in this
   section; users usually connect to a pre-configured Archie server
   merely by typing an "ARCHIE" command line.

2.8.2. GOPHER

   The Internet Gopher protocol was developed at the University of
   Minnesota's Microcomputer Center in 1991, as a distributed
   information search and retrieval tool for the Internet.  Gopher is
   described in RFC 1436 [1]; the name derives from the University's
   mascot.

   Gopher provides a tool so that publicly available information at a
   host can be organized in a hierarchical fashion, allowing it to be
   perused using a simple menu system.  Gopher allows a user to view a
   file on demand without requiring additional file transfer protocols.
   Gopher also has the capability to "link" gophers on the Internet, so
   that each Gopher site can be used as a stepping stone to access other
   sites and reducing the amount of duplicate information and effort on
   the network.

   In many cases, users can access Gopher by TELNETing to a valid Gopher
   location; if the site provides a remote Gopher client, the user will
   see a text-based, menu interface.  The number of Gopher sites is
   growing rapidly; as the dialogue below shows, most Gopher sites have
   a menu item that will allow you to identify other Gopher sites.  If
   using TELNET, login with the username "gopher" (this MUST be in
   lowercase); no password is required.  Note that not all Gopher sites
   provide a remote Gopher client; users may need local Gopher client
   software on their system.

   The Gopher server at "ds.internic.net" has a tremendous amount of
   information for the new user, including lists of frequently asked
   questions and pointers to various Internet discussion lists.  In the
   sample dialogue below, the remote Gopher client is accessed by
   TELNETing to the host.  With the menu interface shown here, the user
   merely follows the prompts.  Initially, the main menu will appear;
   selecting item 2 causes Gopher to seize and display the "InterNIC
   Information Services" menu.  Move to the desired menu item by typing

RFC 1739           Primer on Internet & TCP/IP Tools       December 1994


   the item number or by moving the "pointer" (-->) down to the desired
   entry using the <DOWN-ARROW> key on the keyboard, and then hitting
   <ENTER>.  To quit the program at any time, press "q" (quit); "?" and
   "u" will provide help or go back up to the previous menu,
   respectively.  Users may also search for strings within files using
   the "/" command or download the file being interrogated using the "D"
   command.

   Menu item 7 (selected in the dialogue shown here) is titled
   "Beginners: Start Here", an excellent place for new users to obtain
   information about the Internet, available tools, terms and concepts,
   and, perhaps most importantly, some of the cultural aspects of the
   Internet community.

   Further information about Gopher can be obtained by contacting the
   Internet Gopher Team at the University of Minnesota in Minneapolis
   ([e-mail]).  This is also the site of the first
   Gopher server (consultant.micro.umn.edu).  A Gopher-related
   discussion list is maintained at [e-mail]
   (see Section 3.1 for information on subscribing to Internet
   discussion lists).  More information on Gopher clients can be found
   in the Gopher Frequently Asked Questions (FAQ) file, which can be
   downloaded using anonymous FTP in file
   "/pub/usenet/news.answers/gopher-faq" at the host "rtfm.mit.edu";
   this FAQ also lists sources for a number of Gopher clients for a wide
   range of hardware/software platforms.

2.8.3. Other Information Servers

   There are a number of other information servers that are growing in
   popularity and use.  The problem with being blessed with so much
   information from Archie, Gopher, and other sources is exactly that -
   too much information.  To make it easier for users to locate the
   system on which their desired information resides, a number of other
   tools have been created.

   Veronica (Very Easy Rodent-Oriented Net-wide Index to Computerized
   Archives) was developed at the University of Nevada in Reno as an
   adjunct to Gopher.  As the number of Gopher sites continues to grow,
   it has become increasingly harder to find information in
   "Gopherspace" since Gopher is designed to search a single database at
   a time.  Veronica maintains an index of titles of Gopher items and
   performs a keyword search on all of the Gopher sites that it has
   knowledge of and access to, obviating the need for the user to
   perform a menu-by-menu, site-by-site search for information.  When a
   user selects an item from the menu of a Ve
