Usage of SFTP

From Jasonzhiying

The concept of SFTP

sftp is the abbreviation of Secure File Transfer Protocol, secure file transfer protocol.An encryption method that can provide a secure network for transferring files.sftp has almost the same syntax and functionality as ftp.SFTP, part of SSH, is a secure way to transfer files to the Blogger server.In fact, the SSH software package already contains a secure file information transfer subsystem called SFTP (Secure File Transfer Protocol). SFTP itself does not have a separate daemon process, it must use the sshd daemon process (the default port number is 22) toComplete the corresponding connection and reply operations, so in a sense, SFTP is not like a server program, but more like a client program.SFTP also uses encryption to transmit authentication information and transmitted data, so using SFTP is very secure.However, because this transmission method uses encryption/decryption technology, the transmission efficiency is much lower than that of ordinary FTP. If you have higher requirements for network security, you can use SFTP instead of FTP.(from Baidu Encyclopedia)

Here we use sftp to upload and download files on remote servers and local computers.

Basic usage:

1. Connect to remote server:

sftp [email protected]

Enter the server password after pressing Enter to connect successfully.

2. Upload the file to the server:

put [address of local file] [Where files are stored on the server]

3. Download the file on the server to the local:

get [where the file is stored on the server] [Location to store locally]
