chrome 有 linux 版，已经是很久以前的事了，我就 download 来玩玩，平时也很少用，恰好昨天有个东西要测试，要访问杭州的节点，于是我就拿它出来，并设了一下代理服务器，在杭州搭了个 squid ，就把代理服务器设到杭州了。

印象中，以前所谓的 linux 下的 chrome 是 chromium ，这个是无法配置代理服务器的，而 官方一点的 chrome ，已经具有这个功能了，options -> under the hood -> change proxy settings ，就可以设置代理服务器了。杯具就是这样产生的了！！

我用完代理后，就顺手把 chrome 给关了，proxy setting 当然是没有改回来。

然后，从昨天一直到现在，我使用起网络来，都是怪怪的！！如：

$ curl -I lady.163.com

oh!! no !!!!
我一直百思不得其解！！但又太忙，就不管它了，不能curl ，就ssh 上随便一台服务器 curl 呗。而且，只要我 su 到 root ，就可以正常使用了！！我曾经怀疑，是有人黑了我的 curl 。。。还重装了 curl 呢。。。但还是出错，真是神奇了。。。

直到刚才，实在忍无可忍了！我决定彻查原因！！终于被我通过下面这条命令知道原因了！！
