In TCP implementation, when receiving the SYN request from the client, the server needs to reply the SYN + ACK packet to the client, and the client also needs to send the confirmation packet to the server. Usually, the initial serial number of the server is calculated by the server according to certain rules or adopts random numbers. However, in SYN cookies, the initial serial number of the server is obtained by hash operation and encryption of the client IP address, client port, server IP address, server port and other security values, which is called cookie. When the server suffers from SYN attack and makes the backlog queue full, the server does not reject the new SYN request, but replies the cookie (SYN serial number of the reply packet) to the client. If it receives the ACK packet from the client, the server subtracts 1 from the ACK serial number of the client to obtain the cookie comparison value, and performs a hash operation on the above elements to see if it is equal to the cookie. If equal, complete the three-way handshake directly (Note: At this time, you don't need to check whether this connection belongs to the backlog queue).

I have also seen it spray on cars. The fuel burns to extinguish the flame for more than five minutes. When it finally went out, the whole car head was burned by more than half. Although I don't know the specific figure of the temperature, the comrades in the chemical defense class said it was at least 1300-1500 degrees Celsius, so I thought at that time, even the steel plate could melt into the flame of molten iron in a few minutes. It was not a piece of cake to burn this insect. Even if you are much bigger than the average wasp, may there be steel plates that are resistant to burning? After being ignited by the flame, it should be burned to ashes in an instant. But the result was not what I thought. After being ignited, the big wasp was quite resistant to burning. Actually flying around in the air for more than ten seconds before being burned, the air disintegrated and died. But this has become a good thing, It is precisely because it will burn to death for a while. So flying in the air with flames all over it must be either because of the sharp pain, Either they lost their direction because of something else, Anyway, it is flying around in the air, As a result, they hit many of their peers in the process of flying around. Then it ignited the same kind that was hit, If the ignited kind bumps into each other again, To ignite another kind, It just went through a couple of cycles, Most of the big wasps were set on fire, That will burn quickly. The sky is full of the sound of "crackling" burning meat, and there is a smell of barbecue burnt. The black corpses of wasps that have been burned apart and fallen and the corpses of wasps that have been smashed by bullets are piled up most. One foot is thick enough to reach the knee. That scene, I

Let's put it this way, In the next attack, For the first time, the Vietnamese army and this kind of thing mixed up to fight, This also confirms our previous guess: This is not a native animal, But some kind of "weapon" domesticated by the enemy, As for the course of the battle, Just the same as before, It's just that we have the upper hand, Because the support of the artillery group is coming, More than ten kilometers away, 152, 130 artillery shells into the base into the base to "throw" this way, In front of the position, the floating soil lifted by the shell explosion can reach less than half an arm when it is thickest. Therefore, although the number of Vietnamese troops who failed to sneak attack and changed to storm attack was much larger than ours, There is that kind of thing "help", but in the face of strong firepower, it is still difficult to move. Apart from the upset of the bombed people, there is basically no other end. Anyway, we are especially relieved. I also say that this is revenge for all the dead comrades and Zhou Xiaolin, whose leg has been abandoned. "
