Am I correct that if I have 10k clients doing their worst tricks, and 3 * (80k, my default according to the kernel) == 240k, then I have at most 2.4MB denial of service? Assuming 60k clients, that is only about 15MB of DoS? If true, that is a fairly small time DoS considering the RAM available on today's machines.
Add in the struct sk_buff for each packet as well, which is dependant upon MSS. Thus you could make the clients use a super-small MSS to get more per-packet struct sk_buff overhead. The list goes on and on. At least Linux, unlike BSD, makes an attempt to account for the sk_buff overhead in the limits :-) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
