The attacker first completes the three-way handshake to establish the connection, but in the last ACK reply of the three-way handshake, the TCP window size is set to 0, and then a data request is made. When the attack target sends the request result to the attacker, it stops the data transmission when it finds that the TCP window size is 0, and sends out a TCP window detection packet to ask the attacker if the TCP window has been updated. Since the attacker will not update the window size, the attack target will always maintain the TCP connection and wait for the data to be sent, and continuously carry out TCP window size detection. When the number of controlled hosts in the botnet is large, Target's connection table will gradually be exhausted, resulting in denial of service.一个满口梦想的菜鸟老板，Opama，创办“CRAZYDREAM”公关公司，专门为客户实现各种千奇百怪的梦想。菜鸟老板Opama表面上是个有钱人，其实他手中的存款只够维持公司一个月的开销。他必须在一个月当中带领陆子夜、郑靠朴、LVV、欧阳静秋四个员工走出危机。为了生存，Opama扩大了公司的经营范畴，承接各种千奇百怪的业务：为客户寻找初恋；帮客户分手；帮客户成为明星；帮客户排队买房；帮客户完成临终遗愿……陆子夜、郑靠朴、LVV、欧阳静秋四个性格天马行空的年轻人在疯狂的Opama的领导下，完成了各种疯狂的任务。而这些疯狂的任务背后，展示给观众的却是温暖的人性。陆子夜、郑靠朴、LVV、欧阳静秋四个年轻人也从四个失去信仰和梦想的职场白领，重新开始追寻自己的梦想。而每一集中的客户，也在实现愿望的过程当中，重新找到了勇气。(seven) other materials stipulated by laws and administrative regulations.　　在这起案件中，虽然小女孩亲眼目睹了妈妈被强奸的过程，但由于对方辩护律师强大的能力，这起本来非常明了的官司却变得异常艰难。了解了这件事之后，这位警探主动担负起保护母女二人的责任。(2) Allowances under special working environments and conditions such as middle shift, night shift, high temperature, low temperature, underground, toxic and harmful, etc.;这几大门派开始威逼，不得到谢逊和屠龙刀的下落决不罢休。
