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:
- User id based login (User-id/Password combination)
- Hierarchical folders
- File Management (Rename, Delete, Upload, Download, Download with overwrite, Download with append)
Famous quotes containing the words simple, file and/or transfer:
“A more simple and natural man it would be hard to find. Vice and disease, which cast such a sombre moral hue over the world, seemed to have hardly any existence for him.”
—Henry David Thoreau (1817–1862)
“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)
“I have proceeded ... to prevent the lapse from ... the point of blending between wakefulness and sleep.... Not ... that I can render the point more than a point—but that I can startle myself ... into wakefulness—and thus transfer the point ... into the realm of Memory—convey its impressions,... to a situation where ... I can survey them with the eye of analysis.”
—Edgar Allan Poe (1809–1849)
