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.全职主妇寻找（刘涛 饰）不堪忍受事业狂丈夫向前（杨烁 饰）常年的冷暴力，在对丧偶式婚姻极度失望后产生了抑郁情绪，最终决定重返职场寻找自我。向前经历了婚姻破裂和职场失利的双重考验后也开始反思自己，回归生活。寻找和向前二人经历了婚姻步调不一致的状态，在家庭和自我间进行了断舍离后，实现了治愈人心的二次成长。
