Description

FTP Server is used for file transfer supporting sub-directories, log-in and a set of manipulation commands.

File Transfer Protocol (FTP) is a network protocol used to exchange and manipulate files over a TCP/IP-based network. FTP is built on a client-server architecture and utilizes separate control and data connections between the client and server applications. FTP is used either with user-based password authentication or with anonymous user access.

FTP file manipulation means that you can: create and delete files on FTP server, rename files, create folders and sub-folders, print the folder listings, etc.

FTP can be run in active or in passive mode, which control how the data connection is opened. The mode of operation is defined by the command, received from the client.

• In active mode the FTP Client sends the server the IP address and port number that the client will use for the data connection, and the server opens the connection.
• In passive mode the server sends the client an IP address and port number and the client opens the connection to the server. This mode is used, when the client is located behind a firewall and unable to accept incoming TCP connection.

The FTP Server can also be used to upload HTML pages onto the HTTP Server or to download log files to a remote PC. In this case, the component must be used, and the HTTP Server must be properly configured.

This documentation is separated as follows:

• Control Interface explains how to start/stop the FTP Server and to manage built-in user accounts.
• Access and Multi-User Interface shows how to filter out hosts, which are not allowed to connect to the FTP Server and how to add additional user accounts and to manage access rights for each user.
• A User Callback function sends notifications about events in FTP server to the user application.
• Supported FTP Commands lists the available standard FTP commands that the FTP server understands.
• File System Interface gives you details about the functions that are used to read/write data on the FTP server's storage device.
• Configuration explains the configuration options of the FTP server.
