Chapter 5 Using ConnectPlus with FTP

The RFC959 FTP command set and the commends implemented within a typical FTP client
are not the same. Most FTP client programs and/or libraries that implement FTP APIs
actually take a single client command and turn it into different (possibly multiple) RFC959
FTP commands. You should be aware of this when implementing and debugging software to
interface to the ConnectPlus gateway.
FTP provides for two basic models to transfer data:
• Server/client transfers
• Client (proxy) control of transfers between two servers
Server/Client Transfers
In the server-to-client model, the FTP client initiates the transfer and begins communication
through a protocol communication path with the server. This path is also known as a
control
connection . On both the server and the client, the protocol interface (PI) signals to open a
data connection . The sender (server or client) then gets the data from its file system and
sends it down the data connection to the receiving machine that places the file in its file
system.
