Abstract
This paper describes a convention for specifying longer addresses in
the PORT command.
Introduction
This RFC specifies a method for assigning long addresses in the
HOST-PORT specification for the data port to be used in establishing
a data connection for File Transfer Protocol, FTP (STD 9, RFC 959).
This is a general solution, applicable for all "next generation" IP
alternatives, and can also be extended to allow FTP operation over
transport interfaces other than TCP.
Acknowledgments
Many thanks to all the folks in the IETF who casually mentioned how
to do this, but who left it to me to write this RFC. Special thanks
to Rich Colella, Bob Ullmann, Shawn Ostermann, Steve Lunt, and Brian
Carpenter who had the time and decency to comment on the initial
draft. :-)
1. Background
The PORT command of File Transfer Protocol allows users to specify an
address other than the default data port for the transport connection
over which data are transferred. The PORT command syntax is:
PORT
The argument is the concatenation of a 32-bit internet
and a 16-bit TCP . This address
information is broken into 8-bit fields and the value of each field
is transmitted as a decimal number (in character string
