    The RSKill is TCP resets designed to sever a TCP session. If you put a
    sniffer on the wire, I'm sure you'll see the RST packets being sent, however
    the nimda worm is such a small session that it is over before the TCP RSTs
    can be sent.

    Hello,
    We have a network sensor with the RSKILL response set to
    HTTP_Windows_Executable and HTTP_IIS_Unicode_Translation, to aid in
    protecting from the new nimda worm. However, our web site admin notifies me
    that his logs show those connections actually getting through. The RS
    console logs these SPECIFIC events as being killed. Any help/ideas?
    Thanks.
