200 PORT command successful. Consider using PASV is a response message from an FTP (File Transfer Protocol) server. It indicates that the PORT command, which is used to establish a data connection for file transfers, was successful. However, it also suggests considering using the PASV (Passive) mode instead.
The PORT command is used by the FTP client to inform the server about the IP address and port number it will be listening on for the data connection. In active mode (PORT), the client initiates the connection to the server. On the other hand, in passive mode (PASV), the server opens a port and waits for the client to connect.
Using PASV mode can be beneficial in certain situations, such as when the client is behind a firewall or NAT (Network Address Translation) device that may block incoming connections. By using PASV mode, the client can establish a data connection by connecting to the server's specified IP address and port.
