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.Explores the furthest reaches of the internet and the people who frequently use it, providing a revealing and cautionary look inside a vast cyber netherworld.第二季回归showtime，依旧8集。两年前，我国特种兵郭阳成功诱导T国毒王进入我国边境线进行抓捕，行动中郭阳因队长死亡患创伤后应激障碍退伍。在故事的世界里，彼此命中注定爱人的名字印刻在对方身上，以命运的对象的名字刻在身上的"NAME VERSE"世界为素材的魔幻罗曼史。/listen (listen)他也不爬起来，就伏在地上笑。Although the above code can meet the requirements, it is not easy to expand and difficult to read.
