Simple File Transfer Protocol

Simple File Transfer Protocol, as defined by RFC 913, was proposed as an (unsecured) file transfer protocol with a level of complexity intermediate between TFTP and FTP.

It was never widely accepted on the Internet, and is now assigned Historic status by the IETF.

It is sometimes confused with SSH file transfer protocol, a secured file transfer protocol, also abbreviated as SFTP.

It runs through port 115, and often receives the initialism of SFTP. It has a command set of 11 commands and support three types of data transmission: ASCII, BINARY and CONTINUOUS. For systems which have "WORD SIZE" which are multiples of 8 bits, the implementation of BINARY and CONTINUOUS is the same.

The protocol supports the following:

  1. User id based login (User-id/Password combination)
  2. Hierarchical folders
  3. File Management (Rename, Delete, Upload, Download, Download with overwrite, Download with append)

Famous quotes containing the words simple, file and/or transfer:

    It is very difficult for people to believe the simple fact that every persecutor was once a victim. Yet it should be very obvious that someone who was allowed to feel free and strong from childhood does not have the need to humiliate another person.
    Alice Miller (20th century)

    I have been a soreheaded occupant of a file drawer labeled “Science Fiction” ... and I would like out, particularly since so many serious critics regularly mistake the drawer for a urinal.
    Kurt Vonnegut, Jr. (b. 1922)

    No sociologist ... should think himself too good, even in his old age, to make tens of thousands of quite trivial computations in his head and perhaps for months at a time. One cannot with impunity try to transfer this task entirely to mechanical assistants if one wishes to figure something, even though the final result is often small indeed.
    Max Weber (1864–1920)
