For spoofing attacks, the first thing to consider is to choose the address. For the attack to succeed, the host on the spoofed IP address must not respond to any SYN-ACK packets sent to them. A very simple method that an attacker can use is to disguise only one source IP address, and this IP address will not respond to SYN-ACK packets, perhaps because there is no host on this IP address at all, or because some configuration has been made to the address or network properties of the host. Another option is to disguise many source addresses, and attackers will assume that hosts on some of these disguised addresses will not respond to SYN-ACK packets. To implement this method, you need to recycle the addresses on the list of source IP addresses that the server wants to connect to, or make the same modifications to hosts in a subnet.Put the medicine part into cold water and boil.

This loud cry is called a big one. I can actually hear it very clearly through the interference of the "buzzing" sound. Afterwards, I am still thinking, if there is no "buzzing" sound of these big wasps, how loud is this person's voice? I'm afraid the loudspeakers can't compare with them.Dart VM native extension Dart Sync Socket但是我感觉到时肯定会有大热闹。
