FTP

The FTP connector is a channel for file transfer based on the FTP/SFTP protocol. Through the FTP connector, files can be exchanged with an external FTP server.

The File Transfer Protocol (FTP) is in the TCP/IP protocol group. It consists of two parts: FTP server and FTP client. The FTP server is used to store files. Users can use the FTP client to access resources on the FTP server.
The SSH File Transfer Protocol (SFTP) is a secure version of FTP and a part of the SSH protocol. SFTP enables easy data transmission and data access through the data flow shell. SFTP, also known as the SSH file transfer protocol, provides a secure connection to transfer files and traverses file systems on local and remote systems.

By default, FTP uses TCP ports 20 and 21. Port 20 is used to transmit data, and port 21 is used to transmit control information (commands). Whether to use port 20 as the port for data transmission depends on the FTP transmission mode. In the active mode, the data transmission port number is 20. In the passive mode, the port is determined after the negotiation between the server and the client.
