A SYN-flood attack has the ability to bring the network aspect of your linux box to a snail-like crawl. TCP_SYNCookies protection attempts to stop this from taking a heavy toll on the machine. To enable tcp_syncookies protection, use the following command:

echo 1 > /proc/sys/net/ipv4/tcp_syncookies
