To determine the version of SFTP (SSH File Transfer Protocol) being used, you can use the following steps:
1. Connect to the SFTP server using an SFTP client, such as WinSCP, FileZilla, or PuTTY.
1. Once connected, check the server banner message that is displayed at the top of the client window. This message typically contains information about the server software, including the version number.
1. Alternatively, you can use the terminal or command line interface to connect to the SFTP server and execute the following command:
`sftp -v` This command will display the SFTP version, along with other information such as the server’s fingerprint and the encryption algorithms in use.1. If you do not have access to a client or terminal interface, you can also check the SFTP version by contacting the server administrator or reviewing the documentation for the SFTP server software being used.
