During the establishment of a tcp connection, If the server returns syn and ack messages, The client does not confirm it for some reason. This is because the server needs to retransmit the syn + ack message and wait for the client's confirmation message until the tcp connection timeout. This state of waiting for the client to confirm the connection is usually called a half-open connection. The half-open connection will be kept in the connection table of the server until the connection is disconnected.Another way of Sockstress is to set the TCP window very small, so Target needs to cut the data into several small slices for transmission when transmitting data, which will consume more memory and CPU resources and lead to denial of service.《绝世高手之大侠卢小鱼》强档贺岁！卢小鱼跟随师父白眉修炼快到一年，年关临近，沧海桑田，山下江湖险恶已经不是卢小鱼能应付的了，于是白眉将毕生绝学倾囊相授，好让卢小鱼顺利度过险象环生的春节。托尼由于夜总会关门装修，也亟需一份工作。有个朋友建议他去参加一位音乐博士为了寻找司机所举办的面试。当他到达豪华公寓后，发现这位博士是个名叫唐的黑人古典乐钢琴家，钢琴家正需要一个司机，负责在他举办南方巡演时的接送工作。当然，两人心里都十分清楚，在二十世纪六十年代种族隔离严重的南部地区，他们很容易身陷麻烦之中，但托尼需要钱，而唐需要一个能照顾他的专业司机。给托尼付钱的唱片公司给了他一本“绿皮书”指南，上面列着当地黑人可以吃饭睡觉的地方，因为很多旅馆和餐厅都是只限白人。这些肉你自己吃吧，不许扔了。(4) Within an appropriate distance, radar may not detect small boats, floating ice and other floating objects;
