FTAM — Active vs. passive connect for file transfer (Firewalls....)

  • Key: FTAM-37
  • Legacy Issue Number: 4229
  • Status: closed  
  • Source: DSTC ( Ted McFadden)
  • Summary:

    n Section 4.5.2, the specification provides a sample skeleton of the
    transfer operation where the protocol information available for the
    destination FileTransferSession is "TCP/IP" with a listening address
    of ""

    The specification is requiring that the receiver of a file must allow
    incoming connections.

    Forcing the sender to always connect() and the receiver to always
    listen() will cause unnecessary trouble with firewalls.

    Since any file transfer could also be accomplished by allowing the
    sender to listen and the receiver to make the active connection the
    protocol specification should allow for active, passive (or either)

    (A similar issue was raised against the A/V streams spec: issue #2053)
