Day, no zero display, 1-31Jilin ProvinceThe SYN-Flood attack is currently the most common DDoS attack on the network, It is also the most classic denial of service attack. It takes advantage of a defect in the implementation of TCP protocol. By sending a large number of attack messages with forged source addresses to the ports where the network service is located, it may cause the half-open connection queue in the target server to be full, thus preventing other legitimate users from accessing. This kind of attack was discovered as early as 1996, but it still shows great vitality. Many operating systems, even firewalls and routers, cannot effectively defend against this kind of attack, and it is very difficult to trace it because it can easily forge the source address. Its packet characteristics are usually that the source sends a large number of SYN packets and lacks the last handshake ACK reply of the three handshakes.文革中期，中学毕业的安大伟、罗兰、庄丽等北京知青们，来到了偏远山区成为插队青年。在这片贫瘠的土地上，他们经历着各种各样的人生考验，有人经历了一世无法割舍、深入骨髓的爱情，有人结下了一生难能可贵的友情，同时也有人埋下了后半生的愧疚和自我救赎的种子。返城高潮来临，这群青春热血的年轻人渐次回到了故乡北京，安大伟与罗兰因种种原因就此断了音信。当安大伟终于要与苦等了四年的庄丽登记结婚之日，罗兰重新出现了。与此同时，好友刘洁和于建国的婚姻生活也出现了波折，胖子则还在苦心经营着属于他自己的“返城工程”，每个人都在飞速发展的世界面前，重新经受着生活更严峻的挑战。情感的变异、事业的跌宕、价值观、道德观、爱情观都在拷问着每一个人的灵魂。[Public class ObserverTest {3.
