高易说道：能为大王分忧，是臣的荣幸。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.《铁齿铜牙纪晓岚3》由“好女争锋”、“假作真来真亦假”、“江湖江湖”、“辨奸计”和“胭脂红”五个单元故事组成。故事由神秘的江南女子陆琳琅（张庭饰）的出现而变得一波不平一波又起。陆姑娘深受乾隆（张铁林饰）宠爱，暂住纪晓岚（张国立饰）府上。然而和珅（王刚饰）早知陆姑娘身世， 为斩草除根，多番设计陷害陆姑娘。幸得纪晓岚解救，并一洗陆家冤情。然而这三个老男人却都陷入了儿女情长的重重矛盾中，本不平静的京城更是风波不断。　　钏记酒家有一位沉迷侦探漫画，梦想成为神探的懒散三厨杨得基(马国明饰)，自诩是「钏记林峰」只追求「女神」级高质女生，故至今仍是单身。那是很久以前的事了。那个时候，还没有冥界，天柱连接着天和大地，天空不像现在的天空，那时候的天，悬在云端里。在后世的记载中，它还有一个名字，叫做“昆仑”。人类，是神创造的，世间一切，都是神的子民。昆仑山的天女来到了人间。天女，是神的使者。然而在人类中，出现了一种疾病，那是一种令人丧失心智的疾病，那就是...赵盘成了我们历史上的那个威震千古的秦始皇。
