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.其他人，除了尹旭和英布可以与之一战外，其他人根本就不是对手。故事讲述数学小天才罗克穿越到由数学博士Y统治的数学荒岛，并利用数学知识帮助大家与“黑暗统治”做斗争的故事。日和从今年春天开始就是高中生了，更赞的是她好不容易说服妈妈让她一个人生活，正当日和像只快乐的小鸟前往租屋处时，确发现有人捷足先登!!原来是妈妈担心她自己一个人，所以特地找了儿时玩伴来陪她共同生活，问题奏志是男生啊，妈妈到底是哪根筋不对劲啊……《曼谷爱情故事》是爱情4部曲，分别由时下最火的4首泰语歌曲改编。分成4个地点拍摄，分别是曼谷的暹罗区、老城区、通罗区和沙吞区。四个不同的地点，或是现代化的商业金融中心，m.ysgou.cc或是古老的街道巷口，或者是文艺的城市郊区，上演截然不同的爱情故事。Depending on the profession you intend to enter, you can choose a single course, certificate certification, or diploma in a certain field, such as network or program.
