不翻墙正常使用Gmail和Google阅读器

2011年5月14日 | 分类: 乱七八糟 | 标签: ,

貌似GFW干扰Gmail很久了,据说Gmail SSL封锁规律是每小时的0-19分可访问,20-29分被墙,30-49分可访问,50-59分被墙。听说对Gmail的封锁是我党在出国路由上做的手脚。解决的办法就是把域名解析到不受GFW干扰的谷歌北京IP上。具体步骤如下:

用记事本打开C:\Windows\System32\drivers\etc目录下的hosts文件(如果没有此文件点击下载,修改hosts有些杀毒软件会报毒,允许即可)

添加以下内容到hosts文件,然后保存hosts文件,在开始菜单的附件里找到“命令提示符”打开,输入ipconfig /flushdns命令按回车键清除本地DNS缓存。然后就可以正常使用了,Google香港/Google搜索不会被敏感词重置,Google网页缓存也能正常显示,使用https://mail.google.com/访问Gmail也不会间歇性断开,使用https://www.google.com/reader/即可正常使用Google阅读器(欢迎订阅我的博客http://igfw.net/feed)。

203.208.39.22 webcache.googleusercontent.com
203.208.39.22 mail.google.com
203.208.39.22 www.google.com.hk
203.208.39.22 www.google.com

203.208.39.22是谷歌北京的IP(可以http://tools.whois.net/whoisbyip/查证),由于是国内IP不受GFW干扰(可能受电信运营商干扰)不过安全性未知(有关人士勿用)。

如果你电脑开启了IPv6支持,最好使用Google的IPv6地址,应该也能达到类似效果而且更安全。

    “On this page you find the software we created for the Small Sister Project.
    SmallMail
    We have build a system named SmallMail that contains the SmallMail GUI (or the mail package), the mail client, as well as the SmallMail Server. Of course you don’t need to run your own server and can use one of the available server. We will have a list of available servers present release soon. Further notes are in the software release package as well to be found in the documentation or the faq. Please remember that all software is experimental and used at your own risk. Currently we have the following software:
    The mail application (gui):
    For Windows:
    MicroSister Client 1.0 FINAL BETA – MicroSister_Setup.exe (MicroSister_Source.zip)
    MicroSister Client 1.0 BETA – MicroSister-Setup.exe (of course you can download the sourcecode in .zip-format)
    For Linux:
    SmallMail Client 0.2.1 BETA – tar or zip – SmallMail VCARD-support – README FIRST
    SmallMail Client 0.2.0 BETA – tar or zip – xx-mas release – README FIRST
    SmallMail Client 0.2.0 ALPHA – tar or zip
    The server:
    SmallMail Server version 0.1.1 BETA – tar or zip – xx mas release
    SmallMail Server version 0.1.0 BETA – tar or zip
    There is also a non graphical interface (not maintained):
    SmallMail Test Client 0.1.0 BLEEDING EDGE – tar or zip”
    SmallMail 是基于 Tor 网络的安全邮件传输解决方案,包含一个服务器端和客户端程序

    “FAQ
    Before you get started we can imagine that you have a lot of questions related to the tool. Of course we want to help you understand it. So we compiled an FAQ with general, application and technical details.

    General questions
    1.What is Small Sister? Small Sister is a project that takes on the issue of protecting personal or business information. We want to change the online environment in such a way that private data remains private. One thing is by creating useful, well thought tools and another way is by educating people on the threats at hand.
    2.What tools have you made for me? We have started with a tool that delivers a mail-like application. We have build this in such a way that we protect against data retention (see next question) and eavesdropping. It also enables anonymous communication. So we secure mails at this point. In a future version you may even expect things like instant messaging.
    3.What is data rentention? Data retention means that someone stores information on who is communicating with whom. This information may be harmful when such links between organizations or people are shared too early. Since several countries in Europe have laws that force Internet Providers to store this data certain jobs have become harder and also through wiretapping this kind of information may leak. You can think of journalists that need sources, companies that want to negotiate deals in maximum privacy, people that want to tip authorities anonymously and even intelligence organizations that need to protect our safety.
    4.What is eavesdropping? Eavesdropping means that someone listens in to all the traffic. That enables people to read messages and even when they mails are encrypted, it still shows who you are mailing or receiving mail from.
    5.So if you protect messages what does this do for me? Well you get a tool where you can reach other people as soon as you are in touch. You can freely communicate and exchange information without the burden that you have to consider all communication completely public.

    6.Who is behind this thing? Well the Small Sister Project consists of a group of concerned citizens and professionals with quite some security experience. To get the tool off the ground the Dutch Foundation has funded the project with 25,000 euro. This money has been used to design the tool, build the server software and the client-application.
    7.Are you some bunch of extremists that want to help out criminals? Not really. We are law abiding citizens that need secure communication to our job and want to regain privacy for what it should be: letting us decide who gets our personal information. Even more so: we encourage law enforcement to better secure themselves with this tools, while we hope that criminals don’t use this at all.
    8.Can’t terrorists use this? In theory they can and that is unfortunate. However there are known tools for terrorists to do similar things and we would like to stay away from those tools. However most technologies can be used for good and bad. Most of us use GPS every day without realizing that the attackers on September 11th. 2001 needed it to perform their attack. We focus on positive use and dislike them just as much as you do…………”

    我在WIN7上设置OK了。。蛮好的。。但是我在ANDROID手机不行。

    我有个自己的内部网站,必须改HOSTS才能访问,现在我的Android手机改了HOSTS,可以访问该论坛。

    但是我添加了这些HOSTS,却还是访问不了GOOGLERADER,难道手机浏览器还有什么区别么?

    求教!

      使用手机内置浏览器,清除浏览器缓存再试试,检查下是不是你手机网络限制不能访问HOSTS里的IP了呢?

    非常好用,平均50ms延时,比百度响应得还快。
    其实我们只是想要一个好用的搜索引擎而已,要求也不高,封来封去何必呢。

    直接登录203.208.39.22这个ip发现自己的Google账户是没有登录的,如果此时点击登录会跳到https://www.google.com/accounts/ServiceLogin?hl=zh-CN&continue=http://203.208.39.22/这个网址,下面的提示是:
    您所请求的网页无效。以上两点能说明什么呢?

    • iGFW
      2011年5月15日19:28

      第一个是Cookies的原因
      第二个是说明IP不等当网址那么用

      • 大海
        2011年5月16日22:56

        如果是google官方的网站的话,应该可以获得Cookies并正常登录吧?

        • iGFW
          2011年5月17日00:07

          你换一个美国Google的IP试试

          • 大海
            2011年5月18日22:45

            我使用了一个美国的IP: 74.125.71.104 但仍然是没有正常获取Cookies并登录.
            这下糊涂了,为什么网址就可以而IP就不行呢?

          • iGFW
            2011年5月19日08:59

            IP和网址不能等同的,一个IP上可以绑定多个网站…

    谷歌的gmail服务器是在美国的,即使修改了hosts文件依然还是要链接到美国的服务器,那么为什么修改后能够正常访问呢?你们所谓的转发是什么意思呢?另外GFW对gmail的封锁是这里面的哪种情况啊?http://www.williamlong.info/archives/2195.html

    问题有点多。。我是菜鸟,希望帮忙解答一下,谢谢!!

    • iGFW

      转发大概是指你的请求先发给谷歌北京(这个过程在国内进行不受GFW干扰,GFW干扰发生在出国路由上)然后谷歌北京把数据再发给美国谷歌(这个过程中谷歌应该使用了有关加密技术可以绕过GFW过滤)这样就绕过GFW不会受干扰了。
      应该是间歇性的干扰具体使用的什么技术我就不知道了,不过好像那九种都不像。

  7. 2011年5月14日23:21

    我仍然不建议使用国内的Google服务器。毕竟国内的Google服务器可能只是一个转发(Google也不敢存储用户数据在中国大陆)。
    实际上Google的IP非常多,通过监测软件,甚至是免费的在线监控服务,比如国产的“监控宝”,不断的检测整段的Google IP,可以获取未被GFW列入黑名单中的IP地址。

      我也不建议使用国内的Google服务器。
      “未被GFW列入黑名单中的IP地址”是指没有被墙的还是没有被GFW干扰的(比如Google搜索敏感词不会被重置)。
      “监测软件”这个我不懂有没有相关教程或者推荐一个软件我试试。

    其实目前GFW还勉强可以吧,主要是电信太可恶,目前是电信软件升级,封Google 了,所以这招对付不了电信啊,目前出不去的原因主要在电信了

    • iGFW

      你以为真的是电信想这么干吗,这只不过是gfw封锁了一种形式罢了。

    强就一个字,试试

    就是不知道能用多久。
