1. First handshake: Establish connection. The client sends a connection request message segment, setting the SYN position as 1 and the Sequence Number as x; Then, the client enters the SYN_SEND state and waits for confirmation from the server.
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).
The reason why it is difficult for shareholders to make money is that there are too many opportunities to make money, not the opposite. The more you pay attention to how much money others make, the harder it will be for you to make money. The more you feel that your stock is difficult to make money, the less money your operation will really make. Just like there is a kind of pet called "other people's pet", there is always a kind of stock called "other people's stock". When you see it in your eyes, you lose it in your heart.
