In some mail from Jeff Weisberg, sie said:
"Charles M. Hannum" <mycroft () mit edu> commented: | It also breaks TCP's algorithm for | recognizing stale data. how so? I admit that in writing the code, I was far more concerned with stopping the attack we were under, than I was in any theoretical reliability concerns, but the way we generate the iss (which I cannot take credit for), we will not get values that are slightly less than a previous one for a given set of {saddr,sport, daddr,dport} which should suffice for the above concern.
Hmmm, RFC1948 addresses the issue of generating a good ISS value. Did you implement this ? Darren
