The numbers represent the code for the response and the optional text represents a human-readable explanation or request (e.g. For example, '200' (or '200 OK') means that the last command was successful. The server responds over the control connection with three-digit status codes in ASCII with an optional text message. Further changes were introduced to the passive mode at that time, updating it to extended passive mode. Д«oth modes were updated in September 1998 to support IPv6. In this mode, the client uses the control connection to send a PASV command to the server and then receives a server IP address and server port number from the server, which the client then uses to open a data connection from an arbitrary client port to the server IP address and server port number received. In situations where the client is behind a firewall and unable to accept incoming TCP connections, passive mode may be used.

The server then initiates a data channel to the client from its port 20, the FTP server data port. It sends the FTP command PORT M to inform the server on which port it is listening. In active mode, the client starts listening for incoming data connections from the server on port M.(This sense of 'mode' is different from that of the MODE command in the FTP protocol, and corresponds to the PORT/PASV/EPSV/etc commands instead.) In both cases, the client creates a TCP control connection from a random, usually an unprivileged, port N to the FTP server command port 21. Illustration of starting a passive connection using port 21ДЇTP may run in active or passive mode, which determines how the data connection is established. Protocol overview Communication and data transfer Several proposed standards amend RFC 959, for example RFC 1579 (February 1994) enables Firewall-Friendly FTP (passive mode), RFC 2228 (June 1997) proposes security extensions, RFC 2428 (September 1998) adds support for IPv6 and defines a new type of passive mode. The protocol was later replaced by a TCP/IP version, RFC 765 (June 1980) and RFC 959 (October 1985), the current specification. Until 1980, FTP ran on NCP, the predecessor of TCP/IP. The original specification for the File Transfer Protocol was written by Abhay Bhushan and published as RFC 114 on 16 April 1971. In July 2021, Firefox 90 dropped FTP entirely, and Google followed suit in October 2021, removing FTP entirely in Google Chrome 95. In January 2021, support for the FTP protocol was disabled in Google Chrome 88, and disabled in Firefox 88.0. Many FTP clients and automation utilities have since been developed for desktops, servers, mobile devices, and hardware, and FTP has been incorporated into productivity applications, such as HTML editors. The first FTP client applications were command-line programs developed before operating systems had graphical user interfaces, and are still shipped with most Windows, Unix, and Linux operating systems. For secure transmission that protects the username and password, and encrypts the content, FTP is often secured with SSL/TLS ( FTPS) or replaced with SSH File Transfer Protocol (SFTP). FTP users may authenticate themselves with a clear-text sign-in protocol, normally in the form of a username and password, but can connect anonymously if the server is configured to allow it. FTP is built on a clientвЂ“server model architecture using separate control and data connections between the client and the server. The File Transfer Protocol ( FTP) is a standard communication protocol used for the transfer of computer files from a server to a client on a computer network.
