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.三年前林超科因为与李鹰的理念不合，带着有人类意识的机器人，离开了李鹰。三年后，林超科的女儿林玉，在补习班里遇到一个奇怪的儿童机器人李机。林玉和他很有好感，和他成为朋友。林玉始料不及，李机是李鹰派来的。林玉生日那天，李机潜入林超科家里，想去偷电脑数据，阴差阳错之下，落下泳池发生了故障。林超科在修好他的同时，也给他赋予人类意识。李机成为新人类后，林超科和林玉对他悉心照顾，教导他好好做人，但是李鹰不愿意放弃李机，又对林超科当年带走的机器人耿耿于怀，派出了一个邪恶的机器人。李机林玉，与邪恶机器人斗智斗勇的同时，李机明白了作为人类的责任，林玉也慢慢知道了自己的真正身份……东北某市郊渔村，经营饭店的王笑春本不想参与村长竞选，但是由于村民支持王笑春放弃经营多年的饭店，回来当上了村长。他的养母二婶知道金品三等人的家族势力，怕干不好得罪他们，引来不必要的麻烦，当村长的王笑春顶住了二婶的百般反对与金品三等人家族势力展开了一场集体与个人利益之争，他顶住各种压力，克服了重重困难，得到了全村人民的拥护和信任带领渔村一步一步向社会主义新农村迈进。该剧讲述了以复员军人申天亮为首的新一代党的农村基层带头人，带领村民在党的富民政策指引下，如何尽快脱贫致富，科学利用家乡资源，形成农工贸一体的整体提升家乡发展模式的故事，展现了农村固有的生产方式和农业观念的转变以及由此引发的冲突，向观众展示了一幅新时期农村改革的壮丽画卷。珊瑚也表示，在黛丝学会大靖话之前，她可以照顾她。So the result is?
