Usage Guidelines

Usage Scenario

By default, the listening port number of the FTP server is 21. Attackers may frequently access the default listening port, which wastes bandwidth, deteriorates server performance, and prevents authorized users from accessing the FTP server through the listening port. You can run the ftp server port command to specify another listening port number to prevent attackers from accessing the listening port.

Prerequisites

Before running the ftp server port command to specify the listening port number, you must first run the undo ftp server command to disable FTP services.

Precautions

  • After the ftp server port command is executed, the FTP server disconnects all FTP connections and uses the new listening port.

  • If the current listening port number is 21, FTP client users do not need to specify the port number for logging in to the FTP server. If the current listening port number is not 21, FTP client users must use the FTP server's listening port number to log in to the FTP server.

  • After the listening port number is changed, you must run the ftp server enable command to enable FTP services to make the configuration take effect.

Example

# Change the port number of the FTP server to 1028.
<Huawei> system-view
[Huawei] undo ftp server
[Huawei] ftp server port 1028
