A TCP connection is a quad, and a connection is uniquely determined by the source IP, the source port, the destination IP and the destination port. Therefore, if C wants to forge the packet from A to B, it should fill in the above-mentioned IP header and TCP header with the source IP, source port, target IP and target port. Here B is the server, IP and port are open, A is the target we want to attack, IP certainly knows, but the source port of A is not clear, because it may be randomly generated by A. Of course, if we can find out the rule of generating source port for common OS such as Windows and Linux, we can still do it.

Is this kind of big mouse not only large in size, but also able to withstand bullet attacks? Or are they too fast to be easily hit? " I am somewhat puzzled by what Zhang Xiaobo said. He said his point of view, See if he has any answers, With the experience of strange dogs in position 142 interviewed earlier, Plus he just said that the rat moves quite quickly, So I preconceived that he would say that the reason why these mice are difficult to deal with is similar to that kind of strange dog, because the speed is fast and the movement is flexible, which leads to low fire killing efficiency and short reaction time, which leads to great pressure on position defense.
