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.Console.log ("the leader has come for an interview");为了帮韩颜敏夺回公司，古峰用笔记本把公司写到了自己手里。证监会因此开始调查两人，为了保护公司，两人觉得假结婚。当然，比起证监会，更可怕的是古峰的妈妈——“恶婆婆”顾秀兰，还有又出来捣乱的前女友陈佳佳。古峰和韩颜敏为了户口本和顾秀兰斗智斗勇，在相处中两人却渐渐爱上了对方，古峰大胆求婚，两人假戏真做，书灵也得到了第二样东西：纯洁之吻。Djungling Blue
