They use 'SFTP' to describe the service as being 'secure'. > The server truly is FTP over SSL service (the very first line in the SP's documentation).

SFTP uses port 22, but as you know SFTP is something very different from However some implications use the standard FTP port 21 for FTP and For FTPS the normal port numbers are 989 andĩ90. Servers to accept the draft mechanism AUTH TLS-C. In the later RFC 4217, FTPS compliance required that clients always Methods of invoking FTPS security included AUTH TLS and AUTH SSL. With the FEAT command, although servers are not necessarily required toīe honest in disclosing what levels of security they support. May determine which mechanisms are supported by querying the FTPS server Respond to the AUTH command with error code 504 (not supported). The FTPS server with an unknown security mechanism, the FTPS server will SSL or TLS, it does require the FTPS client to challenge the FTPS This RFC does not explicitly define any required security mechanisms,Į.g. The mechanism for negotiating authentication and security with FTP wasĪdded under RFC 2228, which included the new FTP command AUTH. If a client does not request security, theįTPS server can either allow the client to continue in unsecure mode or Request' security from an FTPS server and then step-up to a mutuallyĪgreed encryption method.
