  • cdpr - Cisco Discovery Protocol Reporter - (2009-05-07)
    • [參考] cdpr is a nifty little command which speaks the Cisco Discovery Protocol, allowing you to learn interesting things from your network.
    • [官網] http://sourceforge.net/projects/cdpr/
    • [套件] debian - cdpr, ubuntu - cdpr
    • 蠻有趣的套件,還可以查出接在哪一個 swicth 上的哪個 port。當然如果 switch 不是 Cisco 出的,大概就看不到資訊了吧。
      jazz@Wdebian:~$ sudo apt-get install cdpr
      jazz@Wdebian:~$ sudo cdpr
