The 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.1600多年以前的东晋末年。是一个士族与平民对立，爱情自由与传统束缚不能并存的时代。摇滚明星的私生子、曾在阿富汗失去了一条腿的退伍军人科莫兰·斯特莱克（Cormoran Strike），如今开了一家破破烂烂的侦探事务所。大学心理学肄业的罗宾·艾拉科特（Robin Ellacott）偶然来到这间事务所做临时雇员，一下子就喜欢上了这份工作。独腿侦探和能干的助手配合默契，开始解决一桩桩疑点重重的案件……该剧改编自J·K·罗琳以“罗伯特·加尔布雷斯”为笔名创作的侦探小说系列，1-3集为《布谷鸟的呼唤》，4、5集为《蚕》，6、7集为《罪恶生涯》。该剧讲述的是金伟带着妻子珍妮琼斯和四岁的儿子查理金来到他阔别10年的故乡——北京，回到他的四合院。金德方为大儿子一家能回国工作高兴不已，逢人就说老大有本事，但他的高兴，无意间引起二儿子、三儿子、小女儿的隐隐醋意的故事。IT opportunities are worldwide.
