- Xen Cloud Platform 預設的網路集線器(switch)
- Open vSwitch reaches 1.0 - (2010-05-19)
- [官網] http://openvswitch.org/
- [套件] 目前尚未看到有人打包套件,應該是因為 Open vSwitch 計畫到了 2010 八月才把原始碼公開吧!!
- 甚至可以取代原有的 Linux Bridge 工具 - Replacing a Linux Bridge with Open vSwitch,期待 Debian / Ubuntu 開始有人打包了....

- ethtool - display or change ethernet card settings
- [簡介] Give Me Liberty or Give Me Eth
- [官網] http://sourceforge.net/projects/gkernel/
- [套件] debian - ethtool, ubuntu - ethtool
- 指令一:取得網路卡的驅動程式版本資訊 - 參考來源: Jserv's blog: ethtool 使用實例
ethtool -i eth0
- 透過指令可以使特定網卡的燈號閃爍數秒 - 參考來源: 準確判斷 eth0 是那一張實體網卡

- 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。
