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.110报警中心接到了私营运输社老板宋伟君的举报，他的儿子被绑架，绑匪开价5万，逾期不付笃定撕票。邢警队长白铁军率领一班人马赶到动物园，轻易地擒获了犯罪嫌疑人谢春。这是一个美艳撩人的少妇，而让警察们难以相信的是，她竟是宋伟君的现任妻子……　　《铃铛记》：康熙厌倦了后宫争宠，太子争储等烦事，独自一人离宫出葫芦狠狠瞪了他一眼，道：别胡说。
