墙者，GWF是也。从技术上来讲，不得不承认他在网络审查领域获得的成功。但，作为一名普通的互联网消费者，实在无法忍受经常重置的链接。我想绝大多数的网民和我一样，只是需要一个信息完整的媒介，像那种关心敏感政治的人毕竟是少数，或许其中有一部分也仅仅只是出于好奇。

自古以来，人类的智慧不约而同的体现在了：兵来将挡，水来土掩。有了墙，自然便会有翻墙之术。可最近，很多翻墙术随着网络审查的紧张失效了。顶顶大名的proxy项目tor也遭遇不幸(如左图所示)：connecting to a relay directory failed(no route to host)[连接到一个中继目录失败（没有找到连通主机的路由器）]，接下来我恐慌的试用了很多其他代理途径，都没有成功。

结果很不巧的在tor的官方博客找到了答案：

As reported, Tor was partially blocked by China on September 25th or so in anticipation of the CCP October 1, 2009 60th anniversary.Here’s what one directory mirror recorded for September。

And here’s the growth of bridge users in response. Alas, like our graphs of bridge use in Iran in June 2009, we only have relative counts for bridge use, not absolute counts. But with a 70x increase in a week, we are talking about 10000+ bridge users:

也就是说，一个叫Bridge的设置可以帮助我们继续翻墙。那么什么是bridge呢？查找了一下官方文档：一些互联网服务供应商(ISP)通过阻断已知Tor的中继器试图防止用户访问Tor网络。Bridge relays(简称bridges)是帮助那些遭受到网络审查的用户连接到tor网络的可行途径。不像其他的relays,bridges没有放在一个公布的列表里。正是因为外界没有一个完整的bridges列表，即使你的ISP过滤掉了所有已知的relays，他们也无法封锁所有的bridges。

获取Bridges:

• You can find public bridge addresses by visiting https://bridges.torproject.org. The answers you get from that page will change every few days, so check back periodically if you need more bridge addresses.
• Another way to find public bridge addresses is to send mail to bridges@torproject.org with the line get bridges by itself in the body of the mail. However, so we can make it harder for an attacker to learn lots of bridge addresses, you must send this request from a Gmail account.

前一个方法，可能已经失效，除非有其他的proxy途径访问那个链接。后者是可行的，但需要用gmail才能获得回信。

获得bridges之后：

Here are your bridge relays:
bridge 84.220.254.169:443
bridge 125.33.17.109:9001
bridge 91.1.111.52:9001
setting ->network ->my ISP blocks connections to the tor network-> add ->ok.至此，你的tor又可以重新使用了。
