使用tor匿名上网

Wednesday, May 2, 2012 3:51:32 PM

首先安装tor
sudo apt-get install tor


然后向bridges@torproject.org发送一封，主题/内容均为"get bridges"的邮件。
稍等片刻后，torproject会回复一封邮件:
[This is an automated message; please do not reply.]

Here are your bridge relays:

 bridge 141.201.27.48:443
 bridge 62.75.185.238:9001
 bridge 83.163.124.123:9001


修改tor的配置文件/etc/tor/torrc, 在末尾添加:
Bridge 141.201.27.48:443
Bridge 62.75.185.238:9001
Bridge 83.163.124.123:9001

不愿透露姓名的群众

YouTube虽是Google旗下的网站，群众依然有权当着Google的面，对其批斗。
来自于YouTube的订阅邮件，光荣地进入了Gmail“垃圾邮件”箱。
这才是群众所需要的<审查>! 我是一位不愿透露姓名的群众!
