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.2.4 Employee Participation身为联邦调查局探员的阿特·杰弗里斯因工作失误而被降级。心情沮丧的他被安排执行一项不起眼的差事，寻找一个患自闭症的9岁男孩西蒙。杰弗里斯没费什么事就找到了目标，但这时的西蒙因父母惨遭杀害，精神上受到严重创伤，一句话都说不出来。在某种意义上说，他们两人是同病相伶。所以杰弗里斯很能理解男孩的心情。同时，多年的工作经验也告诉他，此刻的西蒙也面临危险的处境。事实也的确如此，西蒙是个智力超常的孩子，他无意中破解了军方的密码，而那项代号“水星”的计划是不惜一切代价要保守的机密。这样一来，两个人就成为被追杀的目标……杨长帆能如此拼命杀倭，也是遭过大罪的。伊万·麦克格雷格回归饰演绝地大师欧比旺，海登·克里斯滕森回归饰演达斯·维达，摩西·英格拉姆、乔尔·埃哲顿、Bonnie Piesse、库梅尔·南贾尼、因迪拉·瓦玛、鲁伯特·弗兰德、小奥谢拉·杰克逊、成康、西蒙娜·凯塞尔、本·萨弗迪也出演。诸先生有些被尹旭说动的，或许在他看来，这些诸侯邀请自己不过是看中自己的铸剑术，目的为的就是打造兵器，帮助他们征战四方，争权夺利。
