命令：
nmap -p445 --script smb-vuln-ms17-010 192.168.119.1/24
# mac 报错可以加个sudo
ip对应的子网掩码简单理解：
ip/24
11111111 11111111 11111111 00000000
2^8=256-2=254（台）
ip/16
11111111 11111111 00000000 00000000
2^16=65536-2=65534（台）
ip/8
11111111 00000000 00000000 00000000
2^24=16777216-2=16777214（台）
打印结果：
x.x.x.x/24 = x.x.x.1~255
