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.最后，我张家那些对手就称心如意了。板栗心中惦记王家大少爷和周菡的事，不敢再耽搁，当下晓行夜宿，如急行军一般，于十月十一日来到京都附近。北京的深夜是灯火阑珊，热闹而繁忙的。近年兴起的专车更是在深夜成为城市人出行的主要工具。专车司机李南是一名午夜司机，只在午夜出车。他在专车内邂逅不同的人，见证不同的故事，人间百态，本剧将在一辆专车内还原生活的本来面貌。此事他们也只是道听途说，尚不知其中内情，故而十分兴奋。
