RaspBerry Pi命令行/應用程序-列出IP設備

Question

我正在嘗試制作一個非常簡單的Raspberry Pi應用程序，該應用程序將使用所有IP地址，Mac地址以及它們各自位於同一網絡上的設備名稱進行自動更新。 我完全不知道從哪里開始，關於如何完成此工作的任何建議？

我玩游戲時要連接LCD並將其安裝在路由器旁邊，因此可以輕松訪問連接到網絡的所有設備。

謝謝您的幫助！

“ arp-scan”命令如何？

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

您的接口可能是eth0而不是wlan0。

（已添加）因為arp-scan軟件包中包含舊的供應商列表文件，所以許多設備都無法獲得其名稱（表示為“（未知）”）。 要糾正這一點：

$ 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，我們可以得到如下輸出：

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

所有設備均正確獲得其（供應商）名稱。
