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.14岁的小女孩苏西不幸被一位邻居强奸杀害，升入天堂的苏西眷恋着生者的世界，只能像幽灵一样跟随着她的家人。可吃苦，终归男人的事。36岁的老卡仍然坚持着年少时就已经开始的说唱事业，可微薄的收入却让他的生活十分贫寒，为了孩子将来的生活能有所保障，妻子向老卡提出离婚。这时雪哥却来找老卡让他参加一个说唱比赛的节目，但被老卡拒绝了。雪哥苦口婆心地劝说，终于让老卡重拾信心，决定参加比赛，希望能赢得比赛，挽留妻子。小泽与反对自己玩说唱的父亲关系如同水火不容。直到身为出租车司机的赵父因为疲劳驾驶发生了车祸，才让小泽醒悟，彻底放弃说唱，和父亲一样成为了一名出租车司机。这时说唱比赛开始，小泽为了照顾父亲，选择放弃。却没想到，从父亲的盒子中得知父亲居然一直在为自己攒去音乐学院的学费。小泽十分感动，明白了父亲对他的希望，决定参加说唱比赛。At this point, the event binding is over.而且，每天晚上都睡不着觉。
