FTP Overview The file transfer protocol (FTP) is an application layer protocol for sharing files
between server and client over a TCP/IP network.
FTP adopts the server/client model. Your device can function either as client or as
server (as shown in
Figure 305). They work in the following way:
■ When the device serves as the FTP client, a PC user first telnets or connects to
the device through an emulation program, then executes the ftp command to
establish the connection to the remote FTP server, and gain access to the files
on the server. The device must obtain FTP username and password first to log
onto the remote FTP server.
■ When the device serves as the FTP server, it must be configured with an IP
address so that a user running FTP client program can access it. For the sake of
security, the device does not support anonymous FTP. Therefore, you must use
an authenticated username and password. By default, authenticated users can
access the root directory of the device.

CAUTION:
■ The FTP function is available when a route exists between the FTP server and
the FTP client.
■ When a device serving as the FTP server logs onto the device using IE, some IE
functions are not supported because multiple user connections are established,
and the device supports only one connection currently.
