The sockstreet attack first completes the tcp three-way handshake the tcp connection is established, but in the last ack reply of the three-way handshake, the attacker sets its tcp window to 0 and then makes a data request. When the target discovers that the TCP window size at the receiving end is 0 when transmitting data, it will stop transmitting data and issue a TCP window probe packet to ask the attacker if its TCP window has been updated. Since the attacker does not change the size of the tcp window, the target will always maintain the tcp connection waiting for data to be sent and continuously carry out window update detection. If the attacker uses a large number of controlled hosts to carry out sockstreet attacks, the target will always maintain a large number of tcp connections and carry out a large number of window update detection, and its tcp connection table will gradually run out.　　安宇熙，一名爱好音乐的男生，生活在一个幸福的家庭，爸爸、妈妈，还有一个可爱的妹妹安子熙。安宇熙会经常捉弄妹妹，他把安子熙欺负的哭起来，或者假装生气迫使妹妹隐瞒秘密。突然有一天出现了一个男人自称是安宇熙的生父，安宇熙的身世之谜浮出了水面。 　　同一个城市兄妹二人擦肩而过，再次相见是偶然还是天意？一次选拔活动再次把安宇熙和安子熙的命运联系在一起，他们共同努力，共同进步，安宇熙最终脱颖而出，得到了去一线城市学习发展的机会，妹妹安子熙也希望通过自己的努力将来有一天可以和哥哥再次相聚。电影《飞火流星》是由霍尔果斯首映时代、欢喜传媒、华谊兄弟、和禾和文化传播、北京首映时代文化等公司联合出品，顾长卫执导，白客、蓝盈莹、张海宇、周楚濋、曹骏、王玉雯、李晨晖、蒋易、范明、蒋雯丽等出演的青春校园影片。该片讲述了在高四这个特殊背景下的数段青春爱情故事。电影聚焦于复读时光，当学生们再次面对高考压力时，却依旧无法抑制这青春集中营里的躁动。影片围绕着几个性格迥异的女生展开，组成了一个美好又耐人寻味的青春故事。英国ITV家庭惊悚剧《近亲》由Archie Panjabi和Jack Davenport主演。聪明的心理学家Mona Mirza（Archie Panjabi）在伦敦过着富足优越的生活，她是家庭的主心骨。她珍爱的兄弟在一个海外医疗慈善机构工作时惨遭谋杀，她陷入极度悲伤之中。这起悲剧令隐藏已久的家庭秘密曝光，Mona和家人卷入一张由背叛、阴谋和谋杀编织而成的大网。无论如何，她必须设法保护自己，保护家人，保护岌岌可危的事业。Jack Davenport扮演Mona的丈夫、政治说客Guy Harcourt。Originated in Norway, it is related to people's hunting activities in winter and is a skiing and shooting competition.
