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.Another way of Sockstress is to set the TCP window very small, so Target needs to cut the data into several small slices for transmission when transmitting data, which will consume more memory and CPU resources and lead to denial of service.杨长帆说着便要起身拥过去。四十年前，银环、栓保的故事打动了亿万观众的心，今天，这些朝阳沟的人们又演绎出怎样的精彩故事呢？本剧描写了银环、栓保的儿女们在市场经济的大潮中摆脱父辈宿积的恩怨情恨，带领乡亲们发展经济、建设当代朝阳沟的故事。和舅舅栓保一直结怨的外甥杜志鹏作为朝阳沟村主任上任伊始,就受到作为村书记的姑舅兄弟赵贵山的抵制。为了生态经济的发展,志鹏主动要求封了自己的煤矿;志鹏掏钱给村里修路;开办耐火材料厂解决村子剩余劳动力。志鹏的一系列行为终于感化了贵山。在推广樱桃树的种植中,栓保、银环、巧真、玉蓉、宋鹃解开了家庭的恩怨情结，共同站到了志鹏和贵山带领乡亲们发展朝阳沟经济的事业中来。以福建东山岛的寡妇村为故事原型，讲述1949年仲夏发生在“离岛”上的故事：邱家丫鬟许淑萍被匆匆嫁往离岛不久，一场兵灾就将丈夫王金水和岛上的男人全部抓兵到了台湾，小岛一夜之间成为没有男人的“寡妇村”。淑萍和岛上的女人们一起立誓今世侍奉公婆，给丈夫留一个家。四十个酷暑寒冬，女人们向海神祈祷，日子在没有爱的无穷尽的等待与盼望、希望与失望、诱惑与坚守、奇迹与疯狂中划过。辗转在两岸之间的家书，成为牵系亲情的纽带，也演绎了一段段“家”和“爱”的传奇。1976年南州公安战线的侦察员周志明在“陵园事件”中以渎职罪被判15年徒刑。十年动乱后，他被平反回家，父亲早已离开人间。女友将他接到家中。他在侦破一起“窃密案”中，使女友的姐姐被捕，与女友产生矛盾。后来终于真相大白，与女友重归于好。
