"Because the artillery suddenly 'dumb fire', Later, it was said that it was the same as position 169, because the ammunition consumption was too large and too many shots would be supplied for a while. It was not wrong to say so, because at the peak of the attack, the number of the two strange things released by the Vietnamese army below was too large to count. Have you ever seen ants crossing the river? That's what it feels like, If they are piled together, The density is almost a "ball", So in this case, The firepower of the artillery group is especially strong, Ammunition consumption far exceeded previous expectations, After all, no one expected to meet such a thing at that time, We didn't know how to describe it when we sent back messages on walkie-talkies at the front line. Anyway, it just said that the number of enemies was very large. Hit them hard, It was also the most intensive shelling I have ever seen. In the blink of an eye, It is normal to drop 4-6 shells on an area of about one square meter or even at the same time. The entire position 142 trembled under the shelling, At last, I felt that the ground under my feet would be overturned. Now think about it. If it weren't for the artillery comrades' hard support for us, the dozen or so people and the guys in our hands at that time could not withstand the attack of so many strange things. If they were called to rush up, they would have to tear us up and chew us up.

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. In addition, we can step on the connection port of Car A through a large number of controlled hosts.
