Abstract
In a distributed computing environment, it is often necessary to
transfer files between machines for administrative or record keeping
purposes. Most methods of file transfer either require full-scale
trust by the recipient (e.g., rdist, rcp), the use of a secret
password (e.g., FTP), or some level of pre-arrangement (e.g., rdist,
track). This paper describes filetsf, a generic file transfer system
built on top of the standard lpr/lpd system. Filetsf's advantages
include minimal configuration, the need for minimal trust between
sender and recipient, ordering and spooling of file transfer requests,
and the elimination of the need for shared passwords.
