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.风姿绰约的成衣坊老板娘司小念与清苦郎中晏无明喜结连理，然而大婚之日两人却纷纷离开，原来两人都隐藏着一个反转身份——杀手。面对内心的深爱与隐瞒，两人陷入深深的纠葛……我想着，要是有的话，那夫子就该想到穿件干净衣裳。付宇锋一愣，叉掉弹窗，但是启明网页上，竟然显示他没有权限浏览。白送的？不白送还怎地？你知道他图什么吧？知道啊。　　影片根据一起真人真事，这部电影描述了格利因如何从龙蛇混杂的克里夫兰市掘起，成为当地黑道的执法者。他成功地躲过了无数次的刺杀行动，也残暴的进行还击，把企图刺杀他的人一一铲除。他的凶狠与无敌最终导致全美国的黑帮遭到瓦解。而他也因此赢的了“黑帮杀不死的目标”的名声。如此大破倭寇的机会难得啊。
