- 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

-
- 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.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.
-
- SOURCES:
-
- (1) from the Archie 3.2 manpage, available from any Archie mail or
- telnet site by typing "manpage"
