如何使用终端ping LAN中的所有IP？

Question

我正在尝试使用终端命令 ping 局域网中可用的所有系统。

谁能告诉我如何做到这一点？

Answer 1

您可以安装一个名为nmap.

sudo apt-get install nmap

然后，您可以通过键入以下内容来检查整个网络中是否有所有连接的 IP 地址：

nmap -sP 192.168.1.1/24

上面的命令将扫描从192.168.1.1through开始的所有 IP 地址，192.168.1.254并向您显示所有响应的 IP。

您可以192.168.0.1 - 192.168.1.254通过键入以下内容来扫描其他 IP 地址范围：

nmap -sP 192.168.0.1/23

典型的扫描可能会返回如下内容：

terrance@terrance-ubuntu:~$ nmap -sP 10.0.0.1/24
