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.摇滚明星的私生子、曾在阿富汗失去了一条腿的退伍军人科莫兰·斯特莱克（Cormoran Strike），如今开了一家破破烂烂的侦探事务所。大学心理学肄业的罗宾·艾拉科特（Robin Ellacott）偶然来到这间事务所做临时雇员，一下子就喜欢上了这份工作。独腿侦探和能干的 助手配合默契，开始解决一桩桩疑点重重的案件……非洲大地丧尸肆虐，联合国军队也束手无策只能迅速撤离，此时美军中校墨菲因为飞机失事而流落此地，面对成群的饥饿丧尸墨菲只能在这广袤无垠的非洲大地中展开最后的求生逃亡……Attacking SSL Connections陈老太太又道：这次上京，我们带了五六万银子来，你只管用。何永强闻言，压着嗓子，以极低的音量问道：最近大批倭人在柘林……可是船主安排的？ show_style();。
