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.
"I see, you said the most difficult moment should be the 20 minutes of gun group transfer fire? So in essence, the reason for the fire gap is not that the artillery group has no ammunition, but that the ammunition is used elsewhere, that is, in the task of annihilating the sudden appearance of the Vietnamese artillery group, so during this period of time, you can only rely on yourself to resist the Vietnamese attack, right? "I said.

The construction of intelligent factories is undoubtedly an important way for manufacturing enterprises to transform and upgrade. At the same time, the blueprint for the construction of intelligent factories should be reasonably planned around the medium and long-term development strategy of enterprises and according to the characteristics of their own products, processes, equipment and orders. On the basis of promoting standardization and standardization, starting with the most urgent problems to be solved, we will practically promote the construction of intelligent factories.

In the last article, we explained Redis' master-slave cluster mode in detail. In fact, the configuration of this cluster mode is very simple. It only needs to be configured on Slave's nodes. The configuration of Master's master node does not need to be changed. However, one thing is that the persistent configuration of Master and Slave nodes should be consistent as far as possible, otherwise there will be strange problems. Starting today, we will begin to talk about the second mode of Redis cluster mode. That is, the "Sentinel" mode, which was provided from version 2.6 of Redis, but the mode of this version was unstable at that time. The Sentinel mode did not stabilize until version 2.8 of Redis. In the production environment, if you want to use the Sentinel mode of Redis, you will try to use the version after version 2.8 of Redis. Whether it is master-slave mode or sentinel mode, both modes have a problem and cannot be expanded horizontally, and the high availability of these two modes will be limited by the memory of Master master node. Another point is that the configuration of Sentinel mode is not simple or even complicated, so neither mode is recommended in industrial scenes. If you want to use it, you must have solutions to related problems to avoid subsequent problems.
