Reasons and solutions for "227 Entering Passive Mode" in FTP connection

When you use the FTP client to connect to the FTP server, if you see a message similar to "227 Entering Passive Mode", it means that the FTP server has entered passive mode.

In FTP transmission, there are two main modes: Active Mode and Passive Mode. In active mode, the FTP client will send a data connection request to the server and transmit data on the connection. In passive mode, the server will open a data connection and notify the client to use the connection for data transmission.

"227 Entering Passive Mode" is a response message sent by the server to the client, indicating that the server has successfully entered passive mode and is waiting for the client to connect for data transmission. This message usually contains the IP address and port number of the server. The client needs to use this information to establish a data connection.

When you see this message, the FTP client will try to establish a new connection to transfer data, through which you can upload or download files. This is part of the FTP protocol for data transmission and indicates that you have successfully entered passive mode.

Please note that this is only a part of the FTP connection process, and it will not affect your normal FTP file transfer operation.
