It takes advantage of a defect in the implementation of TCP protocol. By sending a large number of attack messages with forged source addresses to the ports where the network service is located, it may cause the half-open connection queue in the target server to be full, thus preventing other legitimate users from accessing. This kind of attack was discovered as early as 1996, but it still shows great vitality. Many operating systems, even firewalls and routers, cannot effectively defend against this kind of attack, and it is very difficult to trace it because it can easily forge the source address. Its packet characteristics are usually that the source sends a large number of SYN packets and lacks the last handshake ACK reply of the three handshakes.一个男人的故事，他的妻子自杀了，在他看来像个鬼魂，到处跟着他，改变了他的个性。1967年未完成，2020年恢复首映。Abstract Factory: Creates a series of interdependent objects and can change the series at runtime.四个十几岁的朋友，在法国和瑞士边境，他们的生活被世界上最大的粒子对撞机LHC的实验搞得天翻地覆。等以后见了，我就知道他们是什么样的人，这药能不能服用了。
