僵尸扫描：
- 条件较为苛刻，首先要能够进行地址欺骗；
- 其次僵尸机没有什么网络流量产生；
- 最后僵尸机的ipid必须是递增的(win xp及以前windows机型)闲置系统；
1. 僵尸扫描的过程
Port is Open
Port is Closed
僵尸扫描的过程：
1. 扫描者向僵尸机发送SYN/ACK数据包，僵尸机会返回一个RST数据包，记录下ipid为x；
2. 扫描者向目标主机发送SYN数据包(将原地址伪造成僵尸机)；
3. 若目标主机端口开放，则目标主机向僵尸机发送SYN/ACK数据包；
3.1 僵尸机收到SYN/ACK数据包，则向目标主机发送RST数据包，此时僵尸机ipid为x+1；
3.2 扫描者向僵尸机再次发送SYN/ACK数据包，僵尸机返回一个RST数据包，此时ipid为x+2；
4. 若目标主机端口关闭，则目标主机向僵尸机发送RST数据包，此时僵尸机不会产生任何数据包；
4.1 扫描者向僵尸机再次发送SYN/ACK数据包时，僵尸机返回一个RST数据包，此时ipid为x+1；
5. 通过扫描者从僵尸机接收到的两个RST数据包的ipid可以判断目标主机的目标端口是否开放；
