A total of 125,008 times, fast 15 seconds 172 times, only catch 9,266 times.

This watch is bad enough. Our site has been attacked 120,000 times a day, if allowed to make a mess, the Web site will bring the impact of the network is obvious, the attack is characterized by the attack every time by 3-5 different IP at the same time 3-5 times per second attack over, Total up to 9-25 times per second, IP every 1-6 hours, and the IP and previous records are not duplicated. In this way, the Web site memory will suddenly be too large, light, and the other is to bring great instability to the network. Individual IP is sealed has been, I tried all the solution, a solution to a number of IP at the same time to attack, and even make the site seriously overloaded for several minutes.

Now, starting this issue, why can't you stop the new attack? After research, I found that 90% of IP using a new attack scheme: already intelligent can attack 2 minutes to stop 5 minutes of the rotation attack, because my last program parameters set to 600 seconds/period of conservative scheme, so I changed the parameter to 120 seconds 120 new scheme, the wrong kill rate of 0.5%, Through log contrast, I can analyze 120 seconds 120 times wrong kill is not tried, 120 seconds more than 1 times also just have a freight page due to network problems have a customer refresh more than 1 back, this is the reason for our trading background is not intelligent majority.

Finally, thank you for your message, I will think of your message. However, I this procedure is only a reference, local conditions, is not the best, can only say that it is human. Now I send the program again, only to change the time number of parameters, the new parameters have been able to 100% seize those hacker IP, I tried two days, grabbed 62 new IP, or Turkey majority.
