MAP17: ARCHIE


     "If the hill will not come to Mahomet, Mahomet will
      come to the hill." -- Francis Bacon, Of Boldness


Wouldn't it be great if there was some sort of "search" program
that would look through hundreds of different anonymous ftp
sites and tell us where all of the files that we want are
located?

Well, such a search program exists. It is called "Archie".

Archie is actually a collection of servers. Each of these
servers is responsible for keeping track of file locations
in several different anonymous ftp sites. All of the Archie
servers talk to each other, and they pool their information
into a huge, global database that is periodically updated.

"The Archie catalog subsystem maintains a list of about 1200
Internet anonymous ftp archive sites of approximately 2.5
million unique filenames themselves containing 200 Gigabytes
(that is, 200,000,000,000 bytes) of information. The current
catalog requires about 400 MB of disk storage." (1)

You can search this database for file locations simply by giving
an Archie client or server a keyword to search for.

A few minutes ago I did an Archie search using the keyword
"roadmap". Archie sent me back a whole bunch of information
in the following format:

     Host theory.lcs.mit.edu    (18.52.0.92)
     Last updated 06:21 10 Oct 1994

     Location: /pub/areaii
      FILE  -rw-r--r--  159326 bytes  14:52 13 Sep 1994  roadmap.ps

What does all of this tell me? Well, this tells me the address of
the anonymous ftp site is

     theory.lcs.mit.edu

the directory that the file is located in is

     /pub/areaii

and the name of the file is

     roadmap.ps

Archie doesn't retrieve the file for me, but it does tell
me exactly where the file that I am looking for is located.
Once I know the file's location (and its filename), retrieving
the file using ftp is easy!

There are three ways that you can access Archie:

     1. through an Archie client running on your local Internet
        service provider's system,
     2. through a telnet connection directly to an Archie server, or
     3. by sending an e-mail letter directly to an Archie server.

The load on all of the Archie servers is incredible. If your site
has its own Archie client, you should use that client instead of
telnetting or e-mailing to a distant Archie server.

To find out if your site is running its own Archie client, type
the word

          Archie

and see what happens. If you don't get an error message, you can
safely assume that your site has its own Archie client :)

To actually conduct an Archie search using your site's Archie
client, type

          archie <searchterm>

replacing <searchterm> with what you want the client to search
for. For example:

     What you want Archie          What you should
     to search for                 type
     --------------------          ---------------

     files and directories         archie squirrel
     that have the word
     "squirrel" in their
     titles

     files that have the           archie .win32
     extension .win32


ACCESSING ARCHIE BY TELNET

The following are a few of the Archie servers that you can access
using telnet. Please use the username

          archie

to login, and *please* use the server that is closest to you:

          telnet address                  location
          --------------------------      ---------

          archie.au                        Australia
          archie.edvz.uni-linz.ac.at       Austria
          archie.univie.ac.at              Austria
          archie.uqam.ca                   Canada
          archie.cs.mcgill.ca              Canada
          archie.funet.fi                  Finland
          archie.univ-rennes1.fr           France
          archie.th-darmstadt.de           Germany
          archie.ac.il                     Israel
          archie.unipi.it                  Italy
          archie.wide.ad.jp                Japan
          archie.hana.nm.kr                Korea
          archie.sogang.ac.kr              Korea
          archie.uninett.no                Norway
          archie.rediris.es                Spain
          archie.luth.se                   Sweden
          archie.switch.ch                 Switzerland
          archie.ncu.edu.tw                Taiwan
          archie.doc.ic.ac.uk              United Kingdom
          archie.hensa.ac.uk               United Kingdom
          archie.unl.edu                   USA (NE)
          archie.internic.net              USA (NJ)
          archie.rutgers.edu               USA (NJ)
          archie.ans.net                   USA (NY)
          archie.sura.net                  USA (MD)

To start an Archie search using an Archie server that you have
telnetted to, type

          find <searchterm>

replacing <searchterm> with what you want the server to search
for (see example above).

After Archie has finished its search and printed its results
on your screen, you can have Archie e-mail the results to you
by typing

          mail <your Internet address>

replacing <your Internet address> with your full e-mail address.

Finally, to quit your telnet session, type

          quit


ACCESSING ARCHIE BY E-MAIL

To conduct an Archie search via e-mail, send an e-mail letter
to the Archie server closest to you:

          Archie mail address                  location
          --------------------------           ---------

          archie@archie.au                      Australia
          archie@archie.edvz.uni-linz.ac.at     Austria
          archie@archie.univie.ac.at            Austria
          archie@archie.uqam.ca                 Canada
          archie@archie.cs.mcgill.ca            Canada
          archie@archie.funet.fi                Finland
          archie@archie.univ-rennes1.fr         France
          archie@archie.th-darmstadt.de         Germany
          archie@archie.ac.il                   Israel
          archie@archie.unipi.it                Italy
          archie@archie.wide.ad.jp              Japan
          archie@archie.hana.nm.kr              Korea
          archie@archie.sogang.ac.kr            Korea
          archie@archie.uninett.no              Norway
          archie@archie.rediris.es              Spain
          archie@archie.luth.se                 Sweden
          archie@archie.switch.ch               Switzerland
          archie@archie.ncu.edu.tw              Taiwan
          archie@archie.doc.ic.ac.uk            United Kingdom
          archie@archie.hensa.ac.uk             United Kingdom
          archie@archie.unl.edu                 USA (NE)
          archie@archie.internic.net            USA (NJ)
          archie@archie.rutgers.edu             USA (NJ)
          archie@archie.ans.net                 USA (NY)
          archie@archie.sura.net                USA (MD)

and in the body of your letter type

          find <searchterm>
          set mailto <your Internet address>
          quit

replacing <searchterm> with what you want the server to search for,
and replacing <your Internet address> with your e-mail address.

ADDITIONAL ARCHIE COMMANDS

The following Archie commands should work regardless of how you
access Archie:

     help                 Displays a general help screen

     manpage              Displays a *HUGE* manual that tells you
                          everything you could possibly want to know
                          about Archie (including how to limit or
                          expand searches)

     servers              Displays a list of all publicly accessible
                          Archie servers worldwide. The names of the
                          the hosts, their IP addresses and
                          geographical locations are listed.

     whatis <substring>   Searches the Software Description Catalog
                          for the given substring, ignoring case.
                          This catalog consists of names and short
                          descriptions of many software packages,
                          documents (like RFCs and educational
                          material), and data files stored on
                          the Internet.

                               Example:

                                    whatis uucp

                               in part gives as a result:

                               findpath.sh     UUCP Pathfinder
                               logfile-stats   UUCP LOGFILE analyzer
                               mapstats        UUCP map statistics
                                               program.

HOMEWORK:

     If you *REALLY* want to learn more about Archie (and I mean
     *REALLY* want to learn more), try using the "manpage" command
     in the Archie client or server that you are using.
