尽管如此，她还是没能参加比赛。一旁的苏岸出来道：听闻陈平先生高论，苏岸建议此次作战杀鸡禁猴，打姒摇降无诸。陈平笑道：夜色不错，尹将军有兴趣出去走走吗？苏岸站在一边，搞不懂这位陈大人在搞什么？北风呼呼的吹过，秦国地处西北，冬夜格外寒冷。汝贞兄言之有理，可这二人……所以，我们要来这里啊。SYN attack is a kind of DOS attack. It takes advantage of TCP protocol defects and consumes CPU and memory resources by sending a large number of semi-connection requests. SYN attacks can not only affect hosts, but also harm network systems such as routers and firewalls. In fact, SYN attacks can be implemented as long as these systems turn on TCP services no matter what systems are targeted. As can be seen from the above figure, the server receives the connection request (syn=j), adds this information to the unconnected queue, and sends the request packet to the client (syn=k, ack=j+1), then enters the SYN_RECV state. When the server does not receive an acknowledgement packet from the client, it retransmits the request packet and does not delete this entry from the non-connection queue until the timeout. With IP spoofing, SYN attacks can achieve good results, Typically, clients forge a large number of non-existent IP addresses in a short period of time, SYN packets are continuously sent to the server, and the server replies to the confirmation packets and waits for the confirmation of the customer. Since the source address does not exist, the server needs to continuously resend until it timeout. These forged SYN packets will occupy the unconnected queue for a long time, normal SYN requests will be discarded, the target system will run slowly, and in serious cases, the network will be blocked or even the system will be paralyzed.不到晚上，这则消息就以急行军的速度在军中传播开来。
