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.　　在涡流岛上，神圣联军的先头部队遭到幽弥狂及其战友的强力扑杀。随后蛮小满、雪伦（敖磊 配音）、蛮吉随着镜心登岛，惨烈的战斗撼动元泱界的每一个角落……(12.27 update)Magnetic force of grade 10 and magnetic force of grade 8我想多活几年，还是不碰这个了。Well, now the first rule is to accept all messages from 192.168. 1.146, and the count is 0 at this time.
