- Given the number of hosts being used as archive sites nowadays, there
- can be great difficulty in finding needed software in a distributed
- environment. You may know that the software that you need is out there,
- but it can sometimes be difficult to find. The School of Computer
- Science at McGill University has one solution to the problem - "archie".
-
- Archie is a pair of software tools: the first maintains a list of about
- 600 Internet ftp archive sites. Each night software executes an
- anonymous ftp to a subset of these sites and fetches a recursive
- directory listing of each, which it stores in a database. We hit about
- 1/30th of the list each time, so each site gets updated about once a
- month, hopefully balancing timely updates against unnecessary network
- load. The "raw" listings are stored in compressed form on
- quiche.cs.mcgill.ca (132.206.2.3), where they are made available via
- anonymous ftp in the directory ~ftp/archie/listings.
-
- The second tool is the interesting one as far as the users are
- concerned. It consists of a program running on a dummy user code that
- allows outsiders to log onto the archive server host to query the
- database. This is in fact the program we call Archie.
-
- Users can ask archie to search for specific name strings. For example,
- "prog kcl" would find all occurences of the string "kcl" and tell you
- which hosts have entries with this string, the size of the program, its
- last modification date and where it can be found on the host along with
- some other useful information. In this example, you could thus find
- those archive sites that are storing Kyoto Common Lisp. With one central
- database for all the archive sites we know about, archie greatly speeds
- the task of finding a specific program on the net.
-
- Complete anonymous ftp listings of the various sites that we keep in the
- database may be obtained via the 'site' command and for a list of the
- sites which we keep track of, see the 'list' command.
-
- Archie also maintains a 'Software Description Database' which consists
- of the names and descriptions of various software packages, documents
- and datasets that are kept on anonymous ftp archive sites all around the
- Internet. The 'whatis' command allows you to search this database.

- If you have a favourite anonymous ftp site that archie doesn't seem to
- maintain, or if you have additions or corrections to the Software
- Description database, send mail to

- Archie was written and is maintained by Alan Emtage (bajan@cs.mcgill.ca)
- and Bill Heelan (wheelan@cs.mcgill.ca). Peter Deutsch
- (peterd@cc.mcgill.ca) provided (and continues to provide) ideas and
- inspiration.
