The Interface Segmentation Principle (ISP) means that it is better to use multiple specialized interfaces than to use a single total interface. That is to say, don't let a single interface take on too many responsibilities, but should separate each responsibility into multiple specialized interfaces for interface separation. Too bloated an interface is a kind of pollution to the interface.A TCP connection is a quad, and a connection is uniquely determined by the source IP, the source port, the destination IP and the destination port. Therefore, if C wants to forge the packet from A to B, it should fill in the above-mentioned IP header and TCP header with the source IP, source port, target IP and target port. Here B is the server, IP and port are open, A is the target we want to attack, IP certainly knows, but the source port of A is not clear, because it may be randomly generated by A. Of course, if we can find out the rule of generating source port for common OS such as Windows and Linux, we can still do it. In addition, we can step on the connection port of Car A through a large number of controlled hosts.整只未拆的猪头，上边穿着猪尾。1938年，正在日军铁蹄践踏下的北平，发生了一起震撼学界的大事件。日伪当局为镇压学生运动，逮捕了学生会宣传员苏贞(殷桃饰)。暗恋苏贞的北平日清商社董事彭祖康之子彭登科(邓超饰)，不惜冒着生命危险，利用世交的关系，救出了苏贞。自此开始，彭登科和苏贞跨越一生的爱情纠葛拉开帷幕。夜幕降临，一宗诡异的案件正在慢慢揭开序幕。锦阳市唐龙商贸公司总经理肖云庆像往常一样悄无声息的离开了情人韦彩华的家。就在他走进电梯的同时，一个与他穿戴完全一致的男人掏出了打开韦彩华家门的钥匙。一声凄惨的叫喊声撕裂了繁华小区寂静的夜。是自杀还是他杀？刑警队长鲁炼和梁志强意见相左。经过斟酌，局长决定让鲁炼挑头，组成了由即将退休的王维国、女实习警官徐羽，还有经常犯头疼病的秦淼配合侦破的专案组。你想问什么？牧童眼中的戒备神色并未完全褪去，尹旭暗叹：我长的那么像坏叔叔吗？尹旭微笑道：你们都是土生土长的本地人吗？村子里有没有外乡人？或者带我去你们村子，见见你们的父母好吗？牧童们有点发愣，尹旭暗自责备，看来说话太多，小家伙们消化不了啊。
