The first packet discarding scheme will have a slight impact on the user experience, because discarding the first packet retransmission will increase the response time of the service. In view of this, a better TCP Proxy scheme has been developed. All SYN data messages are accepted by the cleaning equipment and processed according to the SYN Cookie scheme. The IP address that successfully established the TCP three-way handshake with the device is determined to be a legitimate user to join the white list. The device disguises the real client IP address, completes the three-way handshake with the real server, and then forwards the data. However, if there is no IP address that shakes hands with the device three times within the specified time, it is determined that the malicious IP address is blocked for a certain period of time. In addition to SYN Cookie combined with TCP Proxy, the cleaning equipment also has the ability to detect a variety of abnormal TCP flag bit packets, and identifies normal access and malicious behavior by returning unexpected responses to SYN messages to test client responses.

4. There are no new varieties of lobsters at present, but crayfish grow differently in different regions. Shrimps are generally imported from the local area. In this way, lobsters do not undergo long-distance transportation, but also adapt to the local geographical conditions and are easy to survive. Where did the seedlings come from? Many people asked for seedlings online. First of all, do you have crayfish in your area? I don't think anyone who wants to raise lobsters now will say that there is no local one, If so, there will be crayfish collectors in the area. From April to May, the number of wild crayfish is very large, Find a shrimp dealer in the street, Let them help you collect, you can choose small specifications, so the price is cheap, small specifications dealers generally can't sell a good price, generally can buy around 5 yuan, of course, this depends on the local actual situation, if there is no local crayfish, shrimp seedlings are not in demand and worthless, more breeding is a little more popular. It is also easy to collect tens of hundreds of catties every morning, Generally, a kilo of 50-200 tails is good, On the same day, it will be transported back to the pond after simple disinfection. It will put about 100kg per mu. After putting it in, it will usually die. Dead shrimps will often be salvaged. Remember to repair the seedlings if you die. No matter whether you bought it from other places or someone else's pond, you will always die if you put it back. If you buy it locally, the price will be low and the cost of dying will not increase much.

The firewall sets the SYN forwarding timeout parameter (the firewall for state detection can be set in the state table), which is much less than the timeout time of the server. When the client sends the SYN packet and the server sends the acknowledgement packet (SYN + ACK), if the firewall has not received the acknowledgement packet (ACK) from the client by the time the counter expires, it sends the RST packet to the server to cause the server to delete the half connection from the queue. It is worth noting that the setting of gateway timeout parameters should not be too small or too large. If the setting of timeout parameters is too small, it will affect normal communication. If the setting is too large, it will also affect the effect of preventing SYN attacks. This parameter must be set according to the network application environment.
