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).Andre? Some of Oppermann's recent studies are to use TCP timestamp options combined with sequence number fields to encode more state information and save the application of those high-performance options, such as TCP window size and TCP selective confirmation option (TCP? Selective? Acknowledge? Options? ) and TCP? MD5 Digest to SYN? Cookies support. This makes SYN? Cookies took a step forward. He eliminated SYN? The cookes implementation does not support these features.I first carried the woman's body out of the door and went to the pumping station in the southwest. Zhao Mou and I walked to the top of the pumping station. The pumping station has a big slope, which is as high as two floors. There is also a small step under the slope. The cave is about 10 meters south after the small step. I dropped the woman's body on the slope and rolled it down, Roll to the position of the abandoned house at the pumping station, We walked down the steps, Continue to move bodies through abandoned houses, To the south steps of the house, Rolled the body down the steps, At this moment, Fu Gang called Zhao Mou and said that they could not move the man's body. Let's both go back and help, After we got back, Fu Gang and Wang Jiying moved the front arm. Zhao Mou and I moved his two legs.
