    anyone know the name(s) and/or a url to find the tool?

    may be one tool or family of tools derived from the same base code (note the
    hand-crafted ID always = 39426 and the Advertised Window = 0x404)

    I'm trying to correlate what I'm seeing on snort with what my personal
    firwall is logging and I want to be able to generate the traffic myself
    (tired of having to wait hours or days between random tests to be farted out
    of the global sewer).

    TIA

    /r
