Because the user name and password are transmitted in clear text, the FTP protocol is not secure. In the same room, as long as one server is under the control of the attacker, it is possible to gain access to the FTP password on other servers to control other servers.Of course, many excellent FTP servers already support encryption. But if the SSH service is already open on the server, we can use SFTP to transfer the data, so why open a process and por
