During this period, due to changes in nerve sensation and metabolism, some people may produce some "strange" sensations. For example, ketone bodies produced by fat decomposition may make people feel a mild sense of excitement. Even if you don't eat continuously, you won't feel hungry or thirsty. Therefore, you won't feel pain because you don't eat.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.薛俊风脸上歇斯底里。然而，中原的官民面对满清入关定鼎同仇敌忾，纷纷拥戴旧明皇室成员，抗清复明。老桂王之子朱田榔在文武百官和李自成李献忠旧部的推戴下，在广东肇庆行宫登基，史称“南明”；率先引动全国的抗清复明之势；南京福王被史可法等立为监国新君。福建唐王在郑成功父子的拥戴下，形成呼应之势，共襄北伐.所以没有注意到。一直在身边的，无可替代的东西。更有一桩：因两家合计，在田上酒家摆流水席，让全村人今儿都不用开伙，随便去哪家吃，或者去酒家吃。黄豆摇头，再次道：你不懂。
