    Could this be backscatter from someone else's SYN floods?  That is,
    could these be packets being sent by a target machine in response to
    packets with a spoofed source address of your machine?  The recent
    paper on using backscatter measurements for some statistical analysis
    of DOS attacks on the internet as a whole may be useful:
