I've got a (TCP) server that handles a big number of new connections per second (1000 - 5000). This causes syn cookies to be send:
kernel: possible SYN flooding on port 2710. Sending cookies.
Syn cookies aren't that bad (in this case), but how do I avoid this. What app or kernel knobs can I turn? Documentation on this appears to be very scarce. The kernel is Linux 2.6.32 x64.
