我想查找所有使用我的 WiFi 连接的设备。
我用了：
nmap -vv -sP 192.168.1.1-100
我可以找到我的本地PC和路由器，但是我无法使用此命令检测到我的Android手机。
网络：
192.168.1.20 router
192.168.1.34 local pc
192.168.1.33 Android phone
nmap：

在 Nmap 上尝试其他修饰符来避免“ping 扫描”：
nmap -sS -sV -vv -n -Pn -T4 192.168.1.1-100
nmap -vv -A -n 192.168.1.1-100
您也可以sudo在之前添加nmap，以确保您拥有所有权限。
