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.　　丛昕施计逼令甘枫加入安妮医院，再找上昔日战友心胸肺外科医生章以芯（锺嘉欣饰）、外科主管麦海琪（周家怡饰）打造出一支完美团队，目的只为拼凑心中蓝图，为兴建香港第一所“儿科中心”铺路。 经历一个个病童的生死故事，令原本势成水火的丛昕与甘枫逐渐解开心结。这个五个来自不列颠的不同地方的人收到了一封同样的恐吓信，上面写着：“我知道你做过什么”。这几个人都有着不可告人的秘密，而未知的来信是否会将他们联系到一起，真相能否被揭开？真琴是个叛逆的高中女生，一次她便车时被车主非礼，经过的藤井清搭救了她。次日，在游行街道上，二人再次邂逅，阿清和真琴来到海边，阿清痛斥真琴对男人以及性的欲望对强暴了她。真琴并没有动怒，反倒是问询他为什么那么愤怒，阿清自己也说不清，只是觉得对一切都不满意。两人的叛逆以及莫名的同感相互吸引着对方。 　　阿清和一个中年有夫之妇有染，那个女人供养着阿清。当真琴等待阿清几日都不见其来电约自己，遂找上门去。阿清提出要和真琴分手，但酒吧里的流氓却要骚扰真琴，阿清为真琴大打出手，两人又再度和好。真琴不顾姐姐的反对，搬来青春就是在奔跑中受伤，又在颠沛流离中期待阳光。青梅竹马的李涛（任宥纶 饰）和张声（廖语辰 饰）因命运相知相识、因网球互助扶持：面对家人对选择网球之路的反对，张声毅然支持李涛；不慎受伤影响网球生涯，是李涛赋予张声前行的力量...两人在一次次挫折中渐明爱意，而张声永远的保护伞卫畅（卢东旭 饰）、心属卫畅的付萌萌（章乐韵 饰）也大胆追梦、勇敢逐爱，即使受伤依然无所畏惧，鲜衣怒马的少年们最终都以青春的意志和昂扬的姿态收获了自己的成长。It can be clearly seen that after the photo is reduced by reducing the exposure and noise, the photo is pure and undistorted.Of course, I will also be led astray by some butterflies.
