In addition, it introduces the SIZE and MDTM commands. It also clarifies the use of REST and introduces a specified way to present the server's directory structure using TVFS (Trivial Virtual File Store). RFC 3659 This RFC introduces the MLS* family of commands for a machine parsable directory listing format.See TLS specifications for further information. It should be noted, that this RFC for the most part also applies to the deprecated FTP over SSL. This RFC describes how to secure the FTP with TLS by using the commands introduced in RFC 2228. Thus this extension seemingly creates incompatibilities where there in fact are none.
However, a few servers and clients are wrongly assuming the local encoding is used for the FTP protocol. Since the original FTP standard did only allow 7-bit US-ASCII as encoding, this extension is fully backwards compatible. RFC 2640 "Internationalization of the File Transfer Protocol"ĭescribes the use of UTF-8 encoding for filenames.This RFC makes the FTP protocol ready for IPv6 RFC 2428 "FTP Extensions for IPv6 and NATs".RFC 2389 "Feature negotiation mechanism for the File Transfer Protocol"ĭescribes the FEAT command to detect available protocol extensions and the OPTS command to change the behaviour of some features.This document describes the mechanism to use different authentication and encryption schemes using commands like AUTH, PROT and related new commands. This document describes the basic FTP protocol. More information about FTP can be found in the Wikipedia article about FTP or in the documents linked below. This allows any computer connected to a TCP/IP based network to manipulate files on another computer on that network regardless of which operating systems are involved (if the computers permit FTP access).
Virtually every computer platform supports the FTP protocol. Any software company or individual programmer is able to create FTP server or client software because the protocol is an open standard. Once connected, the client can do a number of file manipulation operations such as uploading files to the server, download files from the server, rename or delete files on the server and so on. The client computer, running FTP client software, initiates a connection to the server. The FTP server, running FTP server software, listens on the network for connection requests from other computers. There are two computers involved in an FTP transfer: a server and a client. FTP or file transfer protocol is a commonly used protocol for exchanging files over any network that supports the TCP/IP protocol (such as the Internet or an intranet).
