The archie Server (archie is always in lowercase) <PERMIT.ZEN>
A group of people at McGill University in Canada got together and created a
query system called archie. It was originally formed to be a
quick and easy way to scan the offerings of the many anonymous FTP
sites that are maintained around the world. As time progressed,
archie grew to include other valuable services as well.
The archie service is accessible through an interactive telnet
session, email queries, and command-line and X-window clients. The
email responses can be used along with FTPmail servers for those not
on the Internet. (FTP-by-Mail Servers, for info on using FTPmail
servers.)
Using archie Today
Currently, archie tracks the contents of over 800 anonymous FTP
archive sites containing over a million files stored across the
Internet. Collectively, these files represent well over 50 gigabytes
of information, with new entries being added daily.
The archie server automatically updates the listing information from
each site about once a month. This avoids constantly updating the
databases, which could waste network resources, yet ensures that the
information on each site's holdings is reasonably up to date.
To access archie interactively, telnet to one of the existing
servers. {See Telnet, for notes on using the telnet program.} They
include
archie.ans.net (New York, USA)
archie.rutgers.edu (New Jersey, USA)
archie.sura.net (Maryland, USA)
archie.unl.edu (Nebraska, USA)
archie.mcgill.ca (the first Archie server, in Canada)
archie.funet.fi (Finland)
archie.au (Australia)
archie.doc.ic.ac.uk (Great Britain)
At the login: prompt of one of the servers, enter archie to log in.
A greeting will be displayed, detailing information about ongoing
work in the archie project; the user will be left at a archie>
prompt, at which he may enter commands. Using help will yield
instructions on using the prog command to make queries, set to
control various aspects of the server's operation, et al. Type quit
at the prompt to leave archie. Typing the query prog vine.tar.Z will
yield a list of the systems that offer the source to the X-windows
program vine; a piece of the information returned looks like:
Host ftp.uu.net (137.39.1.9)

FILE rw-r--r-- 15548 Oct 8 20:29 vine.tar.Z

archie Clients
There are two main-stream archie clients, one called (naturally
enough) archie, the other xarchie (for X-Windows). They query the
archie databases and yield a list of systems that have the requested
file(s) available for anonymous FTP, without requiring an interactive
session to the server. For example, to find the same information you
tried with the server command prog, you could type
% archie vine.tar.Z
Host athene.uni-paderborn.de
Location: /local/X11/more_contrib
FILE -rw-r--r-- 18854 Nov 15 1990 vine.tar.Z
Host emx.utexas.edu
Location: /pub/mnt/source/games
FILE -rw-r--r-- 12019 May 7 1988 vine.tar.Z
Host export.lcs.mit.edu
Location: /contrib
FILE -rw-r--r-- 15548 Oct 9 00:29 vine.tar.Z
Note that your system administrator may not have installed the archie
clients yet; the source is available on each of the archie servers, in
the directory archie/clients.
Using the X-windows client is much more intuitive---if it's installed,
just read its man page and give it a whirl. It's essential for the
networked desktop.
Mailing archie
Users limited to email connectivity to the Internet should send a
message to the address archie@archie.mcgill.ca with the single word
help in the body of the message. An email message will be returned
explaining how to use the email archie server, along with the details
of using FTPmail. Most of the commands offered by the telnet
interface can be used with the mail server.
The whatis database
In addition to offering access to anonymous FTP listings, archie also
permits access to the whatis description database. It includes
the names and brief synopses for over 3,500 public domain software
packages, datasets and informational documents located on the
Internet.
Additional whatis databases are scheduled to be added in the
future. Planned offerings include listings for the names and locations
of online library catalog programs, the names of publicly accessible
electronic mailing lists, compilations of Frequently Asked Questions
lists, and archive sites for the most popular Usenet newsgroups.
Suggestions for additional descriptions or locations databases are
welcomed and should be sent to the archie developers at
archie-l@cs.mcgill.ca.
