一直從51CTO獲取各種能量，幾年前也暗暗下決心要寫些有用的出來分享給大家。後來一直各種原因未能如願，今天就先分享一個小case，只是記錄一下這個事情，如果這個小case可以幫助到一些人也是很好的 : )
首先說結論：
優酷客戶端，即使沒有人觀看，還是會和外界通信上傳分享帶寬。馬上改設置，改成只要點擊關閉優酷客戶端就馬上退出程序(默認是點擊關閉按鈕繼續保持在後臺運行)。
閒着無聊，配置了家裏的NETGEAR的log郵件自動發送。
一次中午休息時間翻看Email，突然發現一系列的不對勁log，因爲這個時間，家裏小孩應該和外婆都睡着了。不應該會有持續的流量訪問記錄。試着追溯了一下，不看不知道，一看嚇一跳，每天的情況都是這樣。log如下：

已知： 4466是優酷客戶端打通uPNP使用的本地端口。
那麼問題來了，開始提出假設：
1，每天外婆在家裏帶娃，一直都看着電視帶？？？
2，不是外婆看的，那是她們睡覺了以後，有人遠程這臺電腦看的？ 樓主這臺路由器配置了MAC准入，手裏也有家裏所有設備的MAC列表，所以可以確認這個MAC是家裏客廳的臺式機的。
開始求證結論：
抱着驗證的想法，回到家，試着故意開着電腦，開着優酷客戶端，但不進行播放視頻。鎖定以後觀察日誌，發現原來是優酷客戶端的原因，即使沒有人觀看，還是會和外界通信上傳分享帶寬。馬上改設置，改成只要點擊關閉優酷客戶端就馬上推出程序(默認是點擊關閉按鈕繼續保持在後臺運行)。問題解決。
Note：
而且優酷這個客戶端還有個噁心的地方，它會阻止這臺電腦進入休眠，樓主配置了10分鐘進入休眠，但是打開這個客戶端的時候，就久久無法進入休眠，當然這個也有可能是樓主的電腦其它的問題導致。但是關閉這個客戶端，休眠時間到了就正常進入休眠。
