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:
“It is not the simple statement of facts that ushers in freedom; it is the constant repetition of them that has this liberating effect. Tolerance is the result not of enlightenment, but of boredom.”
—Quentin Crisp (b. 1908)
“While waiting to get married, several forms of employment were acceptable. Teaching kindergarten was for those girls who stayed in school four years. The rest were secretaries, typists, file clerks, or receptionists in insurance firms or banks, preferably those owned or run by the family, but respectable enough if the boss was an upstanding Christian member of the community.”
—Barbara Howar (b. 1934)
“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)
