If an attacker sends SYN packets quickly with their own undisguised IP address, this is a so-called direct attack. This attack is very easy to implement because it does not involve spoofing or modifying packets below the user layer of the attacker's operating system. For example, he can simply send many TCP connection requests to implement this attack. However, for this attack to work, the attacker must also prevent his system from responding to SYN-ACK packets because of any ACK, RST, or ICMP (Internet? Control? Message? Protocol) will cause the server to skip the SYN-RECEIVED state (go to the next state) and remove the TCB (because the connection has been successfully established or recycled). Attackers can do this by setting firewall rules, causing the firewall to block all packets (except SYN) to reach the server, or causing the firewall to block all incoming packets so that SYN-ACK packets are discarded before reaching the local TCP handler.　　苏雨晴起初最讨厌的人是李浅然，因为李浅然的邋遢古老的院落，滴答的流水声，悬梁上的女人。乡下的深山中，有一座宋氏老宅，是宋茜祖上的产业。可是宋茜从小到大都被严禁靠近那所宅子。当宋茜问起原因时，所有人都支支吾吾，不愿说出实情，宋茜偷偷潜入老宅，揭开了一个年轻女人在封建社会残酷的身世…那当然。因而她不敢说自家敬文喜欢小葱，觉得过几年也好。Arctic wind Nasra　1979年，香港丽的影视公司（ATV亚洲电视前身）投资拍摄了一部大制作电视连续剧《天蚕变》，该剧的故事大纲是由专门从事武侠剧本创作的创作小组完成的，公映之后收视率节节高升，甚至超过无线电视台当年重头戏目《楚留香》，打破无线多年来收视率不破的神话。
