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.公车司机阿泰（刘冠廷/饰），是一个动作慢吞吞、连手表的时间、地震的感应都比别人慢的奇葩。他每天都会去邮局，找柜员杨晓淇（李霈瑜/饰）寄一封不知道给谁的平信。柜员杨晓淇和阿泰完全相反，是个凡事抢拍的超级急性子，唯独感情生活毫无进展，年近三十还是母胎单身。情人节前夕，杨晓淇被天菜阳光男刘老师（周群达Duncan/饰）搭讪，终于情窦初开的晓淇和刘老师天雷勾动地火；想不到一觉醒来，刘老师再无音讯、而且情人节居然已经过了？！每天来寄信的阿泰也再也没出现过...毫无记忆的杨晓淇，开始了一趟寻找真相的奇幻旅程...《花样男子》决定再次电视剧化。明年春季档，广濑铃担任主演。他忽然觉得，清南村的狗不好惹，清南村的大白鹅夹人，清南村的大公鸡也凶，清南村的牛也好斗，清南村的小女娃尤其难缠。The attacker sends a large number of HTTP messages to the target server through proxy or zombie host, requesting URI (Universal Resource Identifier) related to database operation or other URI that consumes system resources, causing the server to run out of resources and cannot respond to normal requests. For example, HTTP Flood attacks often occur on portal websites. The biggest feature of attacks is to select URIs that consume server CPU or memory resources, such as URIs with database operations.[Miscellaneous Sentences]然后，她迎着他的目光，轻声问道：敬文哥，你为啥难受？是不是因为小葱？她让你伤心了？李敬文想了想。
