A-ddos - Kernel solution to prevent ddos attack
a-ddos is a kernel patch in order to prevent DDos attack at the low-hardware-level. It works well on a netbridge.
DDos is short for distributed denial-of-service,it becomes a serious threat nowadays. There hasn't been a perfect solution yet. a-ddos uses 512M(128M in current version) memory to keep tracks of every ipv4 address and a kernel-level timmer to record connections pre-second. While under attack, only the available IPs are allowed to be connected to the server.
