Editing File Transfer Protocol (section)

==History of FTP servers==
The original specification for the File Transfer Protocol was written by [[Abhay Bhushan]] and published as {{IETF RFC|114}} on 16 April 1971. Until 1980, FTP ran on [[Network Control Protocol (ARPANET)|NCP]], the predecessor of [[Internet protocol suite|TCP/IP]].<ref name="tcpip" /> The protocol was later replaced by a TCP/IP version, {{IETF RFC|765}} (June 1980) and {{IETF RFC|959}} (October 1985), the current specification. Several proposed standards amend {{IETF RFC|959}}, for example {{IETF RFC|1579}} (February 1994) enables Firewall-Friendly FTP (passive mode), {{IETF RFC|2228}} (June 1997) proposes security extensions, {{IETF RFC|2428}} (September 1998) adds support for [[IPv6]] and defines a new type of passive mode.<ref name="clark">{{cite book |last=Clark |first=M.P. |year=2003 |title=Data Networks IP and the Internet |edition=1st |location=West Sussex, England |publisher=John Wiley & Sons Ltd.}}</ref>
