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.
你是谁？你想要什么？你爱干什么？这些都不重要，重要的是你怎么把东西卖出去。《广告狂人》由《黑道家族》的制片人和编剧Matthew Weiner出品，背景设定在上世纪六十年代，聚焦于这个美国梦形成继而破碎的年代，大胆地描述了美国广告业黄金时代残酷的商业竞争。《广告狂人》第二季的故事结束于冷战的全面爆发，彻底击碎了中产阶级独自安于一隅的美梦。第三季的故事从预告片来看也应该走向更加绝望与悲观的阶段。我们不难看出剧集片头中一个男人坠落的画面，不知是隐喻本片的主人公的生活，还是指60年代美国梦的殒落。

Compared with the example of electric lights, file uploading differs in that it will now face more complicated conditional switching relationships. In the example of an electric lamp, the state of the electric lamp is always from off to on and then to off, or from off to low light, low light to strong light, strong light to off. ABCA always seems to follow the rules, so even if you don't use the state mode to write the light program, but use the original if, else to control the state switching, you won't lose yourself in logic writing, because the state switching always follows some simple rules.
