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).

Recently, I was practicing single pass. I met Tank who could not run directly in the picture with the time mechanism. It was very uncomfortable without fire on my hand. I once walked around it for ten minutes before I died (I was not hit by it). So I wanted to ask what was the specific condition for walking around Tank and how to walk around it as quickly as possible. I was really tired of walking around for ten minutes.

"That's what I thought at first, But the actual situation is not that simple, '74 spray' this kind of thing, Each person carries up to three fuel tanks at a time, A fuel tank can only be sprayed once, The advantage of this is that it is sprayed very hard at one time, The number of times that can be sprayed is too small, The four CWs at position 149 each had only two ammunition bases, Is that each person has six fuel tanks, That is, a total of 24 fuel tanks, Before encountering these big wasps, Because of the fierce fighting, The four of them have already consumed 19 fuel tanks, The remaining five fuel tanks were divided equally among the four people. Only the old squad leader of the chemical defense class with the best injection technology took one more. This was to make the limited fuel exert more power as much as possible. After the first battle with the big wasp, all five fuel tanks were sprayed out and the supply could not be available for a while, but the big wasp did not die at one time. "Zhang Xiaobo said.
Suppose the attacker is in an "interconnected" network (e.g. An Autonomous system? System), whose ISP restricts the input and output filtering of the attacker's network traffic, will be able to prevent this spoofing attack-if this method can be deployed to the correct location by the organization. This defense method of traffic input and output filtering will restrict some legitimate communications, such as the mobile IP triangular routing operation mode, so it cannot be widely deployed. IP Security Protocol (IPsec) also provides an excellent way to resist spoofing packets, but this protocol cannot be used due to deployment restrictions. Since it is usually impossible for the server side to require the ISP of the link initiator to implement address filtering or require it to use IP security protocols, more complex solutions are needed to resist this spoofing attack disguised as multiple addresses, which will be discussed later.
