- Archie: The McGill School of Computer Science Archive Server
- Listing Service
-
- 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.
-
- Send comments, bug reports etc to
-
- archie-l@cs.mcgill.ca
-
- 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-admin@cs.mcgill.ca
-
- 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.
