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.历史频道的外星人UFO题材悬疑剧集《蓝皮书计划》续订第2季，仍为10集。29岁的文艺杂志编辑佐佐木幸子(高畑充希 饰)被称为"铁人"，她的职场形象冷静而完美，深受周围人的敬 佩。然而就在婚礼当天，她的新郎俊吾竟然逃跑了。youlady.cc为了忘记俊吾带给自己的伤痛，幸子开始向美食寻求慰籍。杰克（安迪·萨姆伯格 Andy Samberg 饰）是一位精明强干的警探，被他所捕获的罪犯能排上好长一列，然而，在其他同事，包括他那新上任的上司雷（安德鲁·布劳尔 Andre Braugher 饰）眼中，一心追求“成绩”的他似乎有那么一些“不守规矩”。艾米（Melissa Gallo 饰）出生于警察世家，作为家中唯一一个穿上警服的女孩，她明白自己肩上背负着怎样的重担，有些时候，这重担压得她都有些喘不过气了。主人公房东为了生计开了一家事务所。平时接不到大案。只能帮隔壁邻居做做家常。有一天事务所来了一个神秘的人物。交给他一个大案。但前提是他要竟聘上岗。最终如愿。神秘人告诉他有一批从东北亚过来的污染食品。害了很多国人。他已经一举荐将这不法团伙消灭。但被狡猾的坏人溜走了一个。唯一的线索是他身上的体味。那么房东仅凭这唯一的线索能否找到不法分子。By 64 bytes, the SYN packet has been populated and is ready to start transmission. The attack packet is very small, far less than 1500 bytes of the maximum transmission unit (MTU), so it will not be fragmented. So these data packets are like cans on the production line, one packet after another tightly packed together for transmission? In fact, this is not the case.
