I'm referring to <https://datatracker.ietf.org/doc/html/draft-ietf-secsh-filexfer-02> and more recent drafts.
"Even though this protocol is described in the context of the SSH2 protocol, this protocol is general and independent of the rest of the SSH2 protocol suite. It could be used in a number of different applications, such as secure file transfer over TLS RFC 2246 [1] and transfer of management information in VPN applications." -- Shmuel (Seymour J.)

External Message: Use Caution "SFTP is not layered on SSH, but it is secure only when running under SSH or an equivalent." By "SFTP" you are referring to something other than the SSH2 Filexfer protocol?
