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.系列电视剧《水晶眼》是一部不同于当前同类型剧集的单元套剧。二十集四个单元，以更人性化的视角与罪犯展开了斗智斗勇的生死较量，并重点讲述了雷鸣、麦欧这对暗含感情的男女搭档在这些案件中对刑警的新定义，抓罪犯的终极目标并不是把他们送进监狱，而是拯救他们的心灵，让他们重新做人。 　　雷鸣、麦欧在侦破的过程也同样经受着种种考验，其间既有个人感情与国家利益的冲突、也有引导罪犯走向光明的社会责任、更有利欲对他们的考验以及高智商超完美的案件等待着他们的破解，并在最后诠释出新时代刑警在日益高科技化的犯罪中需要更多的革新与默契！ 　　他们是现代的新型特警 ，在侦破案件的过程中，经受着种种考验——其间既有个人感情与国家利益的冲突，更有利欲对他们的诱惑。最终，他们捍卫了新时代刑警的形象。《水晶眼》里面有四个破案故事，主要表现刑警队重案组雷鸣和搭档麦欧明察秋毫，抽丝剥茧，侦破了一个个错综复杂的刑事及民事案件的故事，展现了新时期人民警察的精神风貌，同时也对现代社会中那些被扭曲的人性和变态的情爱进行反思。The first type is implemented through the relationship between the parent class and the child class.时间来到最终决战的两年后，在本应已迎来和平的地球上，怪兽们再度倾巢而出。周夫人在跟前，他不好跟周菡说知己话儿，还是趁早走。
