In TCP protocol, messages arriving at the destination will enter the buffer of the TCP stack and will not be forwarded to the receiving system until the buffer is full. This is to minimize the number of times the system empties the buffer. However, the sender can force the receiving system to clear the contents of the buffer by sending a TCP message with a PSH flag of 1. The TCP PUSH + ACK attack, like the TCP SYN attack, aims to deplete the resources of the victim system. When an attacker sends TCP messages with PSH and ACK flags set to 1 to the Target host, these messages will cause the Target system to clear all TCP buffers (whether the buffers are full or not) and respond with an acknowledgement message. If this process is performed by a large number of controlled hosts, the system will not be able to process normal data, resulting in denial of service.《俏妈新上路 The New Adventures of Old Christine》主创Kari Lizer负责的多镜头喜剧《老妈驾到 Call Your Mother》讲述女主（Kyra Sedgwick饰）是个空巢母亲，孩子们还都在数千里外过着自己的生活，于是她下定 决心要重新插入到孩子们的生活里，成为他们日常的重要部份。有“警察中的警察”之称的监察官，职责是管制警察内部的一切不正之风，是警察最忌讳的职务。其中，有一名监察官，不仅是警察，连事件调查也作为监察对象。这个人就是“被讨厌的监察官”音无一六（小日向文世饰）。在警视厅警务部部长千住辽子（田中美佐子饰）的指示下，音无一六坚持自己的正义，无论如何被人讨厌也要尽好自己的职责，以敏锐的观察力，挑战无数的疑难案件。@哦撸马（阿点）　　Finn Wolfhard饰演Mike，一个备受欺凌的12岁男孩，为了拯救他最好的朋友，他成为了一个让人最意想不到的英雄。他之前参演过《地球百子 The 100》、《Aftermath》、《The Resurrection》。　　还有暗杀者家族被誉为异世界最强的秘术与魔法。
