一直从51CTO获取各种能量，几年前也暗暗下决心要写些有用的出来分享给大家。后来一直各种原因未能如愿，今天就先分享一个小case，只是记录一下这个事情，如果这个小case可以帮助到一些人也是很好的 : )

首先说结论：

优酷客户端，即使没有人观看，还是会和外界通信上传分享带宽。马上改设置，改成只要点击关闭优酷客户端就马上退出程序(默认是点击关闭按钮继续保持在后台运行)。

闲着无聊，配置了家里的NETGEAR的log邮件自动发送。

一次中午休息时间翻看Email，突然发现一系列的不对劲log，因为这个时间，家里小孩应该和外婆都睡着了。不应该会有持续的流量访问记录。试着追溯了一下，不看不知道，一看吓一跳，每天的情况都是这样。log如下：

已知： 4466是优酷客户端打通uPNP使用的本地端口。

那么问题来了，开始提出假设：

1，每天外婆在家里带娃，一直都看着电视带？？？

2，不是外婆看的，那是她们睡觉了以后，有人远程这台电脑看的？  楼主这台路由器配置了MAC准入，手里也有家里所有设备的MAC列表，所以可以确认这个MAC是家里客厅的台式机的。

开始求证结论：

抱着验证的想法，回到家，试着故意开着电脑，开着优酷客户端，但不进行播放视频。锁定以后观察日志，发现原来是优酷客户端的原因，即使没有人观看，还是会和外界通信上传分享带宽。马上改设置，改成只要点击关闭优酷客户端就马上推出程序(默认是点击关闭按钮继续保持在后台运行)。问题解决。

Note：

而且优酷这个客户端还有个恶心的地方，它会阻止这台电脑进入休眠，楼主配置了10分钟进入休眠，但是打开这个客户端的时候，就久久无法进入休眠，当然这个也有可能是楼主的电脑其它的问题导致。但是关闭这个客户端，休眠时间到了就正常进入休眠。
