RaspBerry Pi 命令 Line/Application - 列出 IP 设备

Question

我正在尝试制作一个非常简单的 Raspberry Pi 应用程序，该应用程序将自动更新所有 IP 地址、Mac 地址以及它们各自位于同一网络上的设备名称.我完全不知道从哪里开始，关于如何完成这项工作有什么建议吗？

我尝试连接 LCD 并将其安装在路由器旁边，这样我就可以轻松访问连接到我网络的所有设备。

感谢您的帮助！

"arp-scan"命令怎么样？

$ sudo apt-get install arp-scan
$ sudo arp-scan -l --interface wlan0

您的接口可能是 eth0 而不是 wlan0。

（已添加）因为 arp-scan 包中包含一个旧的供应商列表文件，许多设备无法获取它们的名称（表示为“（未知）”）。要更正：

$ git clone https://github.com/royhills/arp-scan.git
$ sudo cp /usr/share/arp-scan/ieee-oui.txt{,.org}
$ sudo cp arp-scan/ieee-oui.txt /usr/share/arp-scan/

刷新文件后，我们可以得到如下输出：

$ sudo arp-scan -l --interface wlan0
Interface: wlan0, datalink type: EN10MB (Ethernet)

所有设备都正确获得了它们的（供应商）名称。
