If an attacker sends a large number of SYN requests with fake source addresses, the server side will consume a lot of resources to handle this semi-connection, and saving traversal will consume a lot of CPU time and memory, not to mention retrying SYN + ACK on IP in this list. TCP is a reliable protocol, and messages will be retransmitted at this time. The default number of retries is 5. The interval time of retries is doubled from 1s to 1s + 2s + 4s + 8s + 16s = 31s respectively. After the fifth time is sent out, it will take 32s to know that the fifth time has timed out, so the total is 31 + 32=63s.

But we didn't realize it until the first big mouse emerged from the trench of the position. The big rats under the "earth beam" are only a few that dig shallow holes. Most of the deep digging is simply not visible from the surface, This is what I said just now. If you dig shallow, you can barely hit it. You can't see it deep, There is no way out, At last this thing was dug up and emerged directly from the trench wall. Then don't even shake the soil on your body, Bite at the sight of men, As the number of drillings grows, In the end, there were several times more rats than people in the position. Forming a situation of several besieging a soldier, Seeing the urgency of the situation, But 'the lame man caught up with the uneven road' (this is a folk proverb, meaning to make things worse, the house leaks when it rains at night), The big wasps that were repelled for the first time launched another attack, or from the left and right wings, in your words, this also formed the "open space" to cooperate in the battle. It is very strange that the big wasps did not attack the big rats on the ground at one time, but only stung people. They are obviously "a group" of dogs. Alas, then we will fight too badly. " Zhang Xiaobo said with a long sigh here, and I couldn't help but be surprised. This big mouse can dig out more than 100 meters of passages underground in more than half an hour. How fast is this? That's a speed of more than 30 centimeters per minute. Although it is said that the soil on the southern border is softer and no harder than that in the north, it can dig more than 30 centimeters per minute. This speed is really staggering.
