My rationale was that such increase were going to amplify SYN attacks impact by 20% (if we count number of useless SYNACK sent) If the active side sends SYN packets for 180 seconds, do we really want to also send SYNACKS for additional 100 seconds ? Sure, RFC numbers are what they are, but in practice, I doubt someone will really miss the extra SYNACK sent after ~32 seconds, since it would matter only for the last SYN attempted. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
