I have read the RFC 4217, it does not say that. It contains this: The server SHOULD only check the status of the data protection level (for options 3 and 4 above) on the actual command that will initiate the data transfer (and not on the PORT or PASV). The following commands, defined in [RFC 959], cause data connections to be opened and thus may be rejected before any 1xx message due to an incorrect PROT setting ... Nothing indicates that ftp client cannot start writing data to data socket before 1xx reply (but after the connection is established, of course). -- Alexander.
