File eXchange Protocol : ウィキペディア英語版 | File eXchange Protocol
File eXchange Protocol (FXP) and (FXSP) is a method of data transfer which uses FTP to transfer data from one remote server to another (inter-server) without routing this data through the client's connection. Conventional FTP involves a single server and a single client; all data transmission is done between these two. In the FXP session, a client maintains a standard FTP connection to two servers, and can direct either server to connect to the other to initiate a data transfer. The advantage of using FXP over FTP is evident when a high-bandwidth server demands resources from another high-bandwidth server, but only a low-bandwidth client, such as a network administrator working away from location, has the authority to access the resources on both servers. ==Risk== Enabling FXP support can make a server vulnerable to an exploit known as FTP bounce. As a result of this, FTP server software often has FXP disabled by default. Some sites restricted IP addresses to trusted sites to limit this risk.
