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.3. After the "Command Prompt" window is opened, enter the command "Ping Router Intranet Address" and press Enter to detect the connection between the computer network card and the router line.江湖人称天煞星申无害专惩治一些江湖盗贼、土匪之辈。不了解内情的忠义庄薛立忠获此传闻，特邀请武林各门派长老来庄中商议捉拿计划，薛庄主提到，天煞星申无害本是义兄的徒弟，但为了不让江湖人耻笑，为民除害，力誓缉拿归案、查实真假，绝不留情。 行骗高手胜箭和如意嫂听到传闻，捉拿到天煞星能得到黄金一万两黄金。在钱财的诱惑下，两人合力设计擒拿天煞星，并与忠义庄总管事成交，得意忘形的如意嫂想独吞赚来的银票，却被胜箭杀害，这时申无害赶来识破胜箭诡计。原来申无害是被江湖两兄弟相救，幸逃过一劫。申无害想追查师傅葛维义的下落，决定向忠义庄投降，并被关进水牢中。申无害几经周折找到暗道，也找到了师父的遗体，并发现师父身上留下的密信，提到比武擂台下埋藏有炸药，申无害恍然大悟，坚信薛立忠想谋害正在擂台上比武的武林人士，并向薛立忠生死挑战。最终薛立忠被打败，申无害救出众多武林高手的性命，赢得武林众长老的好评。The way bad guys behave should also become the code of conduct for good people.
