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.真是太冤了。DNS NXDOMAIN Flood attacks are similar to DNS QUERY Flood except that they query real domain names.　　书、成两人父亲的犯罪行为最终败露，而萧清却阴错阳差的成了公诉方的关键证人。在爱情和正义之间，萧清艰难做出了正确的选择。在萧清的如山铁证下，书望和成伟终于为他们的违法犯罪行为付出了惨重的代价。经历洗礼的几个年轻人，都收获了成长，对人生、对价值的理解回归了正确的轨道。苏小鹏从台北来到上海准备接收祖产老房子，消息一出，一贯平静的老房子里顿时风声鹤唳谣言四起，住户都开始打起如意算盘。老房子里一户家中无男人的三口人家，女主人看重女儿学业，为其找来了四川妹子吉祥作补习老师。吉祥一直想摆脱自己身上的泥土味做个真正的上海人，然而无论她怎样努力，老房子里的住户仍当她是乡巴佬。但在苏小鹏眼中，吉祥和其它人一样也是上海人，这令吉祥十分开心，开始以上海人的身份带着苏小鹏深入上海的大街小巷，经过朝夕相处，两人生出真情，却遭遇苏小鹏远在台北的爷爷的阻拦。　　热情好交友的杰西很快与大方善谈的莱斯莉成了好朋友。之后的一天，莱斯莉告诉杰西，在森林深处有一个叫特雷比西亚的王国，那里没有任何坏人、也没有整日让你学习的老师、更没有令人讨厌的同学……一切都十分美好。甚至一切的一切都由自己来作主，想怎样就怎样。　　这是一部始于爱情纠结、友情离合、婚姻伦理的言情剧，是讲述特殊时代下普通人的故事，但远远没有结束……
