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.

The real name of this factory is: Hangzhou Green Energy Environmental Protection Power Generation Co., Ltd. Waste Incineration Power Plant (Zihongling, Shaner Village, Puyan Town), Wearing the cloak of environmental protection, it is harmful to one side. As we all know, garbage incineration will release highly toxic dioxin, heavy metal dust and PM2.5, which will directly enter the human body through our breathing, while the other part will fall to the soil, be absorbed by vegetables and other plants and finally enter our body. Dioxin is very toxic, 900 times as much as arsenic. It is called "the poison of the century" and also has reproductive toxicity and genotoxicity. The International Cancer Research Center has listed it as a first-class carcinogen for human beings.

Information Theory: I forget which publishing house it was. It is a very thin book and it is very good. There is a good talk about the measurement of information, the understanding of entropy and the Markov process (there is no such thing in the company now, I'll go back and find it and make it up). Mastering this knowledge, it is good for you to understand the cross entropy and relative entropy, which look similar but easy to confuse. At least you know why many machine learning algorithms like to use cross entropy as cost function ~
Another effective method is that after the car owner stops, he can adjust the car air conditioner to the highest temperature state of 32 ℃, allowing warm air to blow dry the moisture in the evaporator and air conditioning pipes of the air conditioner. This can not only blow dry the evaporation box and ventilation pipe quickly, but also kill some mold existing on the evaporation box and ventilation pipe of the automobile air conditioner, thus better preventing the peculiar smell of the automobile. However, this method is generally not easy to do and is more troublesome.
