  • Alexa 是流量統計的網路服務,今天無意間玩了一下中心的流量統計,發現三個有趣的現象:
    • 其一:搜尋關鍵字 - Clonezilla, Clonezilla Live, 再生龍, drbl, co-life 進榜前十大
    • 其二:流量在12月、1月、4月出現高峰,都恰巧是 Clonezilla Live 釋出新版的時間點,關聯性頗高。
    • 其三:我架設的 sensor6.nchc.org.tw 佔中心 6% 的流量,應該是研考會"台灣看透透"的連結威力。

Networking

  • cdpr is a nifty little command which speaks the Cisco Discovery Protocol, allowing you to learn interesting things from your network.
    • 蠻有趣的套件,還可以查出接在哪一個 swicth 上的哪個 port。
      jazz@drbl:~$ sudo apt-get install cdpr
      jazz@drbl:~$ sudo cdpr
