No.6 Jackson YeeSYN 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.　　逃亡途中，他们不仅要对付各种各样令人棘手的突发事件，还要与追捕他们的执法官库利斗智斗勇。这个锲而不舍地家伙发誓要把这三个“脱网之鱼”送回监狱。这一路上意外不断，状况百出，究竟他们能否获得真正的自由？Abnormal name: Poisoning　　正当平安在爱情与报仇间作一抉择之际，方正查出尹明扬之死与警司有关而遭灭口，敖明的安危受到威胁，平安毅然拿起金枪，连番枪战立即爆发……豆渣这东西最去油污某维和地区，维和警察执行护送各国人员去往机场的路上突遇恐怖分子袭击，炸毁了道路，中国维和警察不得不带领众人前往密林逃生，美国无国界医生雷娜.当地向导李大石和随队工程师特拉法在逃生路上听到恐怖的象冢传说都惴惴不安，在李大石错误的引导下，众人陷入更大危机，导致内部矛盾不断，中国维和警察不得不解决内忧外患的危机情况。在一路被追杀的他过程渐渐发现，这一行人的身份都不简单，原来这次的恐怖袭击是蓄谋已久的复仇，如今的受害者是当年的施暴者，而残酷战争的因果即将到来，维和警察能否带领大家安全逃生，完成这次的致命行动？
