The principle is that syn messages are first responded to syn_ack by DDOS protection system. With a specific sequence number (recorded as a cookie). The real client returns an ack and the Acknowledge number is cookie+1. The fake client will not respond. In this way, we can know that the clients corresponding to those IP are real and add the real client IP to the white list. The next access passes directly, while other forged syn messages are intercepted. The following is a schematic diagram of protection:?

5. After setbacks, I didn't devote myself very much to the middle and late stages. I held the mentality of loving death and running. I stopped eating. Although I often encouraged myself, I was unable to recover from the situation in the later stages. I had to wait for 2014. It was no longer cost-effective to invest again in the later stages. When this place is not suitable, we must make a decisive decision, either continue to invest to improve the foundation, or change to a better ready-made site and don't invest blindly. Talk about why I gave up this place, want to continue to raise, want to solve the water source, drill a tractor well to 20,000, pond silt deepest place 80 centimeters, to clean up is too difficult, at least the foundation has to invest 40,000 yuan, a small area of about 15 mu, is not worth the big investment, have to give up.
