Phase A Metering SectionThe attacker appears to have subscribed to my microblog. Not long after this article was published yesterday, I was attacked again. He bypassed CDN and directly attacked the source server (I don't know how the IP address leaked). The traffic was larger than last time.The sockstreet attack first completes the tcp three-way handshake the tcp connection is established, but in the last ack reply of the three-way handshake, the attacker sets its tcp window to 0 and then makes a data request. When the target discovers that the TCP window size at the receiving end is 0 when transmitting data, it will stop transmitting data and issue a TCP window probe packet to ask the attacker if its TCP window has been updated. Since the attacker does not change the size of the tcp window, the target will always maintain the tcp connection waiting for data to be sent and continuously carry out window update detection. If the attacker uses a large number of controlled hosts to carry out sockstreet attacks, the target will always maintain a large number of tcp connections and carry out a large number of window update detection, and its tcp connection table will gradually run out.《傲慢与偏见与僵尸》的作者是塞斯·格拉汉姆-史密斯（Seth Graham-Smith），他沿用奥斯汀的故事设定和语言风格，讲述了伊丽莎白·班纳特所在的小镇降临了一场瘟疫，很多人都变成了僵尸，伊丽莎白立志要把僵尸全部消灭掉，然而傲慢无礼的达西先生的到来，打乱了她的计划，经过一番斗嘴和好，两人开始携起手来对付僵尸，最终拯救了小镇。因为有了之前的恩情在，还有和赢子夜之间的这层姻缘，这比合作就这就算是谈成了。原本郑青木是想等他会试过了再提的，那样面子上也好看不是，中了进士也能配得上黄家小姐的身份。
