Simple File Transfer Protocol

from Wikipedia, the free encyclopedia
SFTP in the TCP / IP protocol stack :

Network access Ethernet Token
bus 		Token
ring 		FDDI ...

The Simple File Transfer Protocol ( SFTP ) is a simpler version of the File Transfer Protocol (FTP). It has now been classified as historic by the IETF and is rarely used these days. The Simple File Transfer Protocol is easily confused with the SSH File Transfer Protocol (also: Secure File Transfer Protocol ), which is also abbreviated to "SFTP".

Simple File Transfer Protocol was designed for simpler machines, but offers more options than the Trivial File Transfer Protocol (TFTP). The functional scope of the SFTP includes access control, file transfer , listing of directory contents , changing the current directory as well as renaming and deleting files and directories.

In contrast to FTP, SFTP only uses a single TCP connection, which is normally established via port 115.
