    RE: FCIP iFCP encapsulation proposal



    Sorry, I think we have a severe case of red herring here.  Any number of
    unlikely scenarios has been hypothesized, none of which (assuming
    there is any security in creating a TCP/IP connection at all) will
    cause any useful or dangerous behavior in either a SCSI target or
    a SCSI initiator.
    
    As an example, the information transmitted by FTP is first processed into 
    FTP messages, which are then inserted on IP transfer units, which are
    then placed into Ethernet or other transport frames.  Those frames
    have addressing which routes them to a destination.  The IP layer
    unpackages the IP units, which are in turn unpackaged into FTP units
    for treatment by an FTP protocol only.
    
    Even if you delivered an FTP string transferring a bit-level trace 
    to an FCIP device (not normally
    possible, because there would have had to be a TCP/IP connection formed
    between the FTP emitter and the FCIP receiver) the FTP encapsulation of
    the data could never be interpreted as legal SCSI commands by 
    a SCSI device.  The FTP string would not invoke the necessary 
    valid responses for the statefully responding SCSI device.
