Bold, careful and thick-skinnedThe above example is a fact verified by writing code. As for the reasons, it will be analyzed in detail in this article. Here, it is only to illustrate that the above points need to be considered.　　谁知约会当晚，子欣却失约了。原来在子欣的办公室对面，另一家公司的老板张申然长久以来一直注视着她。在她失落期间，两人通过彩色贴纸交流，子欣也渐渐喜欢上了这个大男孩。子欣忘记了和启宏的约定，与申然约在某咖啡厅见面，而申然却睡在了另一个女人的床上。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.
