2.1 google search

If you only need Google search, then here I got a few mirrors for you:

//wen.lu http://gunduzi.duapp.com/

Aol uses Google search engine and it is not blocked.

//www.aol.com https://www.quora.com/How-can-I-bypass-the-Great-Firewall-of-China?share=1

The GFW basically uses three methods:

DNS pollution IP blocking TCP filtering

Actually Google was blocked by the third method only before this May, only when individuals were searching some certain words, they might be blocked from Google for some time.

However, due to some unknown reasons, GFW reinforced its interruption for Google since this May. Now GFW use first and second method to prevent mainlanders from using Google. Here comes the solutions:

People may know that there is not only one IP for http://www.google.com, there are plenty of them. Moreover, Google provides some ISPs and commercial companies a service called "Google Global Cache". So there are many copies of Google and thus thousands of hundreds of Google Global Cached IPs are available for us.

Dealing with "DNS pollution", we can easily change the local DNS to a unpolluted one (Unfortunately, good DNSs such as 8.8.8.8 are mostly blocked in China). Or we can setup a hosts file to redirect urls to right IPs. Hosts is actually a file in your computer or Mobile phone that owns a priority to redirect the url to the IP you assigned. For example: if you write "127.0.0.1 www.google.com" in your local hosts file, then whenever you type www.google.com in your browser and go, you will be led to 127.0.0.1.

There are several people who collect GGC IPs that are not blocked in China and write them in hosts files to avoid the DNS pollution. I can give you several of those. imouto.host （Latest one unblocked some youtube videos！） Smart Hosts huhamhire-hosts You can easily find your hosts file in Windows: C:\windows\system32\drivers\etc Mac: Shift + ⌘ + G and type in "/etc/hosts", then press Enter Linux: the same way as Mac For other system please search the internet What you need to do is copy the content in hosts file you download and paste into your local hosts file, or you can just replace the hosts file.

There are several software can deal with the DNS pollution with more intelligent methods such as holmium/dnsforwarder and ChinaDNS, you can read the setup instruction on their project pages.

There exist several different methods that allows you not only use Google but also use those IP-blocked websites like Facebook, Twitter and YouTube. HTTP/HTTPS proxy (such as GoAgent, a software based on Google App Engine and python's urlfetch method) Socks proxy (such as ***, you can easily setup one with a VPS or find some free account) SSH shell (often use with PuTTY, a high speed solution) VPN (famous ones like Astrill, VPNgate) APNP (easy to use proxy, especially on iOS)…

GoAgent is basically the best freeware I have ever used that allows you to browse most of the blocked websites. However, as GoAgent is a software based on Google App Engine, it can be really difficult to use since this May. You can read the establish instruction on the project page: InstallGuide - goagent - 图文教程, If you have trouble reading Chinese, just read this one instead: How To Install And Use Goagent. GoAgent works perfectly with Chrome extension "Switchysharp Proxy", you can easily setup your own rules to route the proxy.

VPNgate is a project based on Softether, it is a project funded by University of Tsukuba, Japan. VPNgate collects thousands of free VPNs that you can use. VPNgate is free of charge. No registration is required. You can read more on its introduction page: VPN Gate Overview

For Paid services, I would not like to recommend those in Public, I don't want to do advertising. If you need recommendations for paid VPN providers, do not comment below, send me messages.

2.2 修改 DNS 服务器

DNS
domain name system

OpenDNS IPv4 address： 208.67.222.222 208.67.220.220

OpenDNS IPv6 address： 2620:119:35::35 2620:119:53::53 台湾中华电讯的DNS： 168.95.192.1 168.95.192.2

香港宽频的DNS： 203.80.96.9 203.80.96.10

修改ip地址、修改网关、修改DNS服务器、重新启动网络配置 复制代码

2.2.1 修改ip地址

[root@L160 ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0　　//修改对应网卡的ip地址的配置文件。如果你有多个网卡那么ifcfg-eth就有多个，你可以连续按俩次Tab键查看

DEVICE=eth0 #描述网卡对应的设备别名，例如ifcfg-eth0的文件中它为eth0

BOOTPROTO=static #设置网卡获得ip地址的方式，可能的选项为static，dhcp或bootp，分别对应静态指定的 ip地址，通过dhcp协议获得的ip地址，通过bootp协议获得的ip地址

HWADDR=00:0C:29:0C:B1:00 #（物理地址）对应的网卡物理地址

IPADDR=192.168.2.160 #（IPv4地址）如果设置网卡获得 ip地址的方式为静态指定，此字段就指定了网卡对应的ip地址 NETMASK=255.255.255.0　　#（子网掩码）网卡对应的网络掩码

ONBOOT=yes #系统启动时是否设置此网络接口，设置为yes时，系统启动时激活此设备 （下面的是可以不填写的） BROADCAST=192.168.2.255 #对应的子网广播地址 NETWORK=192.168.2.0　　#（网关）网卡对应的网络地址 IPV6INIT=no

IPV6AUTOCONF=no

2.2.2 修改网关

[root@L160 ~]# vi /etc/sysconfig/network NETWORKING=yes #表示系统是否使用IPV4网络，一般设置为yes。如果设为no，则不能使用网络，而且很多系统服务程序将无法启动 NETWORKINGIPV6=no #不懂IPV4和IPV6的请百度科普 HOSTNAME=L160 #设置本机的主机名，这里设置的主机名要和/etc/hosts中设置的主机名对应 GATEWAY=192.168.2.1 #设置本机连接的网关的IP地址

2.2.3 修改DNS服务器

[root@L160 ~]# vi /etc/resolv.conf

#这个域名服务器可以换成你本地的，好处是网络访问要快上那么一点点 search localdomain nameserver 8.8.8.8 #（主）google域名服务器 nameserver 8.8.4.4 #（从）google域名服务器

2.2.4 重新启动网络配置

#俩个命令选择一个就行了 [root@L160 ~]# service network restart Shutting down interface eth0: [ OK ] Shutting down loopback interface: [ OK ] Bringing up loopback interface: [ OK ] Bringing up interface eth0: [ OK ] [root@L160 ~]# /etc/init.d/network restart Shutting down interface eth0: [ OK ] Shutting down loopback interface: [ OK ] Bringing up loopback interface: [ OK ] Bringing up interface eth0: [ OK ]

2.3 修改 hosts 文件”

　　刚才介绍了“修改 DNS 服务器”。但是刚才俺也说了，“修改 DNS 【无法】对付域名污染”。咋办捏？要对付域名污染，有一个比较简单的方法——修改 hosts 文件。下面来介绍一下。 　　大部分操作系统都支持 hosts 文件，它提供了 IP 的“别名机制”。这种基于 IP 的别名机制，既可以用来对抗前面提到的“域名污染”，也可以对付“域名劫持”。

◇如何设置

　　如果你使用 Windows 系统，可以使用如下命令打开 hosts 文件。 notepad %SystemRoot%\system32\drivers\etc\hosts

　　如果你使用 Linux 系统或苹果的 Mac 系统，可以用如下命令打开。 vi /etc/hosts

　　打开之后，把那些被封锁的网站的 IP 及域名加入 hosts 文件（每行一个）即可。比方说，上述提到的 Google Drive，它的 IP 是 74.125.227.198，那我们只要在 hosts 加入如下一行： 74.125.227.198 drive.google.com 　　然后就可以像往常一样使用基于 HTTPS 协议的 Google Drive 了。

◇优缺点分析

　　使用此招数的好处在于： (1) 非常傻瓜化——不需要安装软件； (2) 性能很好——当中无需经过代理的中转。 　　但是有好必有坏，此招数的坏处也很明显： (1) 如果你访问的是 HTTP 协议的网页，且内容包含敏感词，那么此招数照样没戏； (2) 如果 ＧＦW 不光封域名，还封 IP，那么此招数也还是没戏； (3) 如果某个网站的 IP 已经变化了，那你就要与时俱进地修改你的 hosts 文件，煞是麻烦。

　　综上所述，修改hosts文件的法子，只能用于诸如 Google Drive 之类影响力巨大的网站。因为 Google Drive 用的人已经比较多，ＧＦW 不好意思把整个域名及 IP 段都封杀。因此，只好选择性地封锁 HTTPS 协议，而对 HTTP 协议网开一面（HTTP 协议是明文的，便于 ＧＦW 进行关键词过滤）。这种情况下，“修改 hosts 文件”的招数就可以派上用场了。

2.4 加密 Web 代理

keywords: 加密 Web 代理;

Web 代理
proxy server

刚才提到了“修改 Hosts 的局限性”——无法对抗 IP 黑名单。如果某个网站的 IP 地址被列入 GFW 的黑名单，修改 Hosts 文件是没戏的。

主要好处是：无需安装其它软件，光靠浏览器就可以搞定。不过捏，HTTPS 代理一旦用的人多了，容易引起 ＧＦW 的注意，死期也就不远了（正所谓人怕出名猪怕壮）。如果你想用这招，就得经常去逛一些代理网站。 　　本来俺在这个FQ教程中，会附带放几个 HTTPS 的 web 代理，便于大伙儿直接使用。可惜自从2010年3季度，ＧＦW 开始盯上俺了（貌似 ＧＦW 的走狗，也在看俺的博客）。所以捏，俺就不把具体的加密 Web 代理放出来了，以免便宜了那些走狗。想要的同学，自己去 Google 一下。

2.5 代理工具

FQ软件的同步密钥 BTLZ4A4UD3PEWKPLLWEOKH3W7OQJKFPLG

注意事项:

由于使用加密的方式穿透 ＧＦW，所以性能上肯定会打折扣滴。 建议大伙儿同时用两个浏览器：一个浏览普通的网站，另一个配置好代理浏览被墙的网站。 对于使用 Firefox 或 Chrome 的同学，也可以安装一些第三方的代理插件（比如：AutoProxy、FoxyProxy），用来自动切换代理模式和非代理模式。 　　如今很多FQ工具的 exe 可执行文件都自带了“数字签名”。如果你不是从官方网站下载该文件，最好查看一下数字签名， 以确保该文件没有被篡改（比如感染病毒）。至于如何验证数字签名，请FQ看“这里”

2.5.1 赛风

　　赛风也是老牌的FQ软件。早期的“赛风2”仅提供网页代理。从“赛风3”开始，推出了客户端软件。这个客户端很牛B，同时支持基于 SSH 的代理模式和VPN模式（关于VPN模式，本文后续会介绍）。而且，它也是单个绿色软件，也很小巧（几兆），且带有数字签名。（如何验证数字签名，请FQ看“这里”） 　　如果赛风使用 VPN 模式FQ，你所有的网络软件无需任何设置，就能跟着FQ；如果赛风使用代理模式FQ，则开启两个端口：“8080”端口用于HTTP代理，“1080”端口用于 SOCKS 代理。 　　更多关于赛风的详细介绍，请看俺博客的帖子《双管齐下的赛风3》 　　官方站点在“这里”（已经被墙）。 　　【免FQ】获取的方法： 　　你只需往赛风官网提供的邮箱 get@psiphon3.com 发送任意邮件，立马就能收到自动回复。在回信中，直接就附上了赛风的可执行程序 （如果邮件里的附件名叫“psiphon3.asc”，改为“psiphon3.exe”即可直接运行）

2.5.2 蓝灯

　　蓝灯是2013年才诞生的后起之秀。刚开始的 1.x 版本，依赖于“邀请机制”，不适合大规模推广。 　　它在2015年8月发布 2.0 版本，开始提供傻瓜化的“一键式FQ”。俺尝试了之后，感觉不错，就在博客上推荐了——参见《Lantern（蓝灯）——开源且跨平台的FQ代理》。 　　蓝灯需要安装才能使用，不过安装包很小巧（几兆），而且自带数字签名。与其它FQ代理相比，蓝灯的特色是——开源且跨平台。这方面跟 TOR 有点像。 　　它使用 HTTP 代理的方式，端口是“8787”。 　　官方站点在“这里”（已经被墙）。 　　【免FQ】获取的方法： 　　https://github.com/getlantern/lantern-binaries 　　上述链接位于 Lantern 官方的 GitHub 帐号（到目前为止，GitHub 全站都可以【免FQ】访问），该页面同时提供三大桌面操作系统（Windows、Linux、Mac）的安装包。

2.5.3 TOR

  • Tor evades censorship using encrypion

　　TOR 也叫“洋葱网络”。网上常听人说的“带套（TOR 的谐音）穿墙”就是指它。这玩意儿是一个开源项目，用于保护个人上网的自由和隐私。它的工作原理可以参见“这里”。 　　由于 TOR 的名气太大，ＧＦW 特别关照它。很多 TOR 的网桥中继都被 ＧＦW 列入 IP 黑名单，导致 TOR 无法单独使用。不过从2014年10月份，TOR 开始内置了 meek 插件，该插件重新让 TOR 复活（又可以独立联网了）。具体教程参见《TOR 已复活——meek 流量混淆插件的安装、优化、原理》。 　　【免FQ】获取的方法： 　　大伙儿可以通过邮件方式获取 TOR。具体如下： 　　先发送主题为“help”的纯文本邮件到 gettor@torproject.org ，收到回信后根据邮件的提示再回复一次，即可在你的邮箱中收取 TOR 的软件包。强烈推荐使用 Gmail，以确保最佳效果。尽量别使用国内的邮箱，切记！

　　另外，还可以用 TOR 跟其它FQ工具搭配，构造双重代理。双重代理的隐匿性非常好，如果你经常在网上发表敏感言论，要记得使用双重代理。关于双重代理的扫盲教程，请看俺写的系列博文《如何隐藏你的踪迹，避免跨省追捕》。 https://www.torproject.org/download/download#warning

  1. Configuration

    ## Configuration file for a typical Tor user
    ## Last updated 22 September 2015 for Tor 0.2.7.3-alpha.
    ## (may or may not work for much older or much newer versions of Tor.)
    ##
    ## Lines that begin with "## " try to explain what's going on. Lines
    ## that begin with just "#" are disabled commands: you can enable them
    ## by removing the "#" symbol.
    ##
    ## See 'man tor', or https://www.torproject.org/docs/tor-manual.html,
    ## for more options you can use in this file.
    ##
    ## Tor will look for this file in various places based on your platform:
    ## https://www.torproject.org/docs/faq#torrc

    ## Tor opens a SOCKS proxy on port 9050 by default – even if you don't
    ## configure one below. Set "SOCKSPort 0" if you plan to run Tor only
    ## as a relay, and not make any local application connections yourself.
    #SOCKSPort 9050 # Default: Bind to localhost:9050 for local connections.
    #SOCKSPort 192.168.0.1:9100 # Bind to this address:port too.

    ## Entry policies to allow/deny SOCKS requests based on IP address.
    ## First entry that matches wins. If no SOCKSPolicy is set, we accept
    ## all (and only) requests that reach a SOCKSPort. Untrusted users who
    ## can access your SOCKSPort may be able to learn about the connections
    ## you make.
    #SOCKSPolicy accept 192.168.0.0/16
    #SOCKSPolicy accept6 FC00::/7
    #SOCKSPolicy reject *

    ## Logs go to stdout at level "notice" unless redirected by something
    ## else, like one of the below lines. You can have as many Log lines as
    ## you want.
    ##
    ## We advise using "notice" in most cases, since anything more verbose
    ## may provide sensitive information to an attacker who obtains the logs.
    ##
    ## Send all messages of level 'notice' or higher to /var/log/tor/notices.log
    #Log notice file /var/log/tor/notices.log
    ## Send every possible message to /var/log/tor/debug.log
    #Log debug file /var/log/tor/debug.log
    ## Use the system log instead of Tor's logfiles
    #Log notice syslog
    ## To send all messages to stderr:
    #Log debug stderr

    ## Uncomment this to start the process in the background… or use
    ## –runasdaemon 1 on the command line. This is ignored on Windows;
    ## see the FAQ entry if you want Tor to run as an NT service.
    #RunAsDaemon 1

    ## The directory for keeping all the keys/etc. By default, we store
    ## things in $HOME/.tor on Unix, and in Application Data\tor on Windows.
    #DataDirectory /var/lib/tor

    ## The port on which Tor will listen for local connections from Tor
    ## controller applications, as documented in control-spec.txt.
    #ControlPort 9051
    ## If you enable the controlport, be sure to enable one of these
    ## authentication methods, to prevent attackers from accessing it.
    #HashedControlPassword 16:872860B76453A77D60CA2BB8C1A7042072093276A3D701AD684053EC4C

    ## Once you have configured a hidden service, you can look at the
    ## contents of the file "…/hiddenservice/hostname" for the address
    ## to tell people.
    ##
    ## HiddenServicePort x y:z says to redirect requests on port x to the
    ## address y:z.

    ################ This section is just for relays #####################

    ## See https://www.torproject.org/docs/tor-doc-relay for details.

    ## Required: what port to advertise for incoming Tor connections.
    #ORPort 9001
    ## If you want to listen on a port other than the one advertised in
    ## ORPort (e.g. to advertise 443 but bind to 9090), you can do it as
    ## follows. You'll need to do ipchains or other port forwarding
    ## yourself to make this work.
    #ORPort 443 NoListen
    #ORPort 127.0.0.1:9090 NoAdvertise

    ## The IP address or full DNS name for incoming connections to your
    ## relay. Leave commented out and Tor will guess.
    #Address noname.example.com

    ## If you have multiple network interfaces, you can specify one for
    ## outgoing traffic to use.

    ## A handle for your relay, so people don't have to refer to it by key.
    ## Nicknames must be between 1 and 19 characters inclusive, and must
    ## contain only the characters [a-zA-Z0-9].
    #Nickname ididnteditheconfig

    ## Define these to limit how much relayed traffic you will allow. Your
    ## own traffic is still unthrottled. Note that RelayBandwidthRate must
    ## be at least 75 kilobytes per second.
    ## Note that units for these config options are bytes (per second), not
    ## bits (per second), and that prefixes are binary prefixes, i.e. 210,
    ## 220, etc.
    #RelayBandwidthRate 100 KBytes # Throttle traffic to 100KB/s (800Kbps)
    #RelayBandwidthBurst 200 KBytes # But allow bursts up to 200KB (1600Kb)

    ## Use these to restrict the maximum traffic per day, week, or month.
    ## Note that this threshold applies separately to sent and received bytes,
    ## not to their sum: setting "40 GB" may allow up to 80 GB total before
    ## hibernating.
    ##
    ## Set a maximum of 40 gigabytes each way per period.
    #AccountingMax 40 GBytes
    ## Each period starts daily at midnight (AccountingMax is per day)
    #AccountingStart day 00:00
    ## Each period starts on the 3rd of the month at 15:00 (AccountingMax
    ## is per month)
    #AccountingStart month 3 15:00

    ## Administrative contact information for this relay or bridge. This line
    ## can be used to contact you if your relay or bridge is misconfigured or
    ## something else goes wrong. Note that we archive and publish all
    ## descriptors containing these lines and that Google indexes them, so
    ## spammers might also collect them. You may want to obscure the fact that
    ## it's an email address and/or generate a new address for this purpose.
    #ContactInfo Random Person <nobody AT example dot com>
    ## You might also include your PGP or GPG fingerprint if you have one:
    #ContactInfo 0xFFFFFFFF Random Person <nobody AT example dot com>

    ## Uncomment this to mirror directory information for others. Please do
    ## if you have enough bandwidth.
    #DirPort 9030 # what port to advertise for directory connections
    ## If you want to listen on a port other than the one advertised in
    ## DirPort (e.g. to advertise 80 but bind to 9091), you can do it as

    ## forwarding yourself to make this work.
    #DirPort 80 NoListen
    #DirPort 127.0.0.1:9091 NoAdvertise
    ## Uncomment to return an arbitrary blob of html on your DirPort. Now you

    ## Uncomment this if you run more than one Tor relay, and add the identity
    ## key fingerprint of each Tor relay you control, even if they're on

2.5.4 代理工具的优点 & VPN 的缺点

　　大部分代理工具都是免费的，而 VPN 软件很多是商用软件，要花钞票滴。少数不花钱的VPN，也有使用期限或者流量限制。
　　另外，由于 VPN 需要在你的系统中安装虚拟网卡，因此VPN软件都不是绿色软件，且多半需要管理员权限才能安装。这对于俺这种偏好绿色软件的用户来说，也是一个明显的缺点。

◇VPN 的优点 & 代理工具的缺点

　　由于 VPN 虚拟出一个网卡，你使用的各种软件（浏览器/聊天工具/邮件客户端）无需任何设置，就可以直接通过这个虚拟网卡传输数据。这是VPN的一大优点。

2.7 手机FQ

 

2.7.1 代理软件

　　手机系统也可以运行FQ代理。比如无界、赛风、TOR 都有提供了手机版。

2.7.2 VPN

　　智能手机上，也可以跑 VPN 客户端。这样，就可以让手机通过 VPN FQ。以广受欢迎的 Android 为例，它支持 OpenVPN、PPTP、L2TP 等多种类型的 VPN。由于 VPN 前面刚介绍过，此处不再啰嗦。
　　说到手机上的 VPN FQ，建议大伙儿尝试一下 fqrouter。关于这款工具在天朝之内已经广为使用，很傻瓜而且稳定性也不错。它的扫盲教程请看《fqrouter——安卓系统FQ利器（免 ROOT）》。

◇手机浏览器

　　手机浏览器为啥能穿墙捏？大致原理是这样滴：由于手机对于网络流量比较敏感，为了尽量压缩网络流量，某些手机浏览器采用代理服务器的方式运作。比如当你企图访问某个网页时，浏览器并不是直接向该网站请求数据，而是通过手机浏览器对应的一个代理服务器去请求，然后由代理服务器拿到的数据进行压缩和优化，然后再回传给手机浏览器。
　　采用上述方式的手机浏览器，如果代理服务器设置在国外，是有希望突破 ＧＦW 滴。由于党国的封锁越发严厉，很多手机浏览器默认的代理服务器都被屏蔽了。因此，要通过手机浏览器FQ，需要通过修改浏览器软件，让它不使用默认的代理服务器，改用你指定的服务器。
　　不同的手机浏览器，改服的办法也不尽相同。限于篇幅，俺不再作详细介绍，仅给出几款手机浏览器改服的文章。

21.2 Windows Remote Desktop Connection

Remote Desktop can't connect to the remote computer for one of these reasons:

  1. remote access to the servier is not enabled

Windows Remote Desktop is the remote access software built into the Windows operating system.
No additional download is necessary to use the program.

Host Side

To enable connections to a computer with Windows Remote Desktop,
you must open the System Properties settings (accessible via Control Panel)
and allow remote connections via a particular Windows user through the Remote tab.

You do have to set up your router for port forwarding so another PC can connection to it from outside the network,
but this is usually not that big of a hassle to complete.

Client Side

The other computer that wishes to connect to the host machine must simply open the already
installed Remote Desktop Connection software and enter the IP address of the host.

Tip: You can open Remote Desktop through the Run dialog box (open it with the Windows Key + R shortcut); just enter the mstsc command to launch it.

Most of the other software in this list have features that Windows Remote Desktop doesn't, but this method of remote access seems to be the most natural and easiest way to control the mouse and keyboard of a remote Windows PC.

Once you have everything configured, you can transfer files, print to a local printer, listen to audio from the remote PC, and transfer clipboard content.

Remote Desktop Availability

Windows Remote Desktop can be used on Windows from XP up through Windows 10.

However, while all versions of Windows can connect to other computers that have incoming connections enabled, not all Windows versions can act as a host (i.e. accept incoming remote access requests).

If you're using a Home Premium version or below, your computer can only act as a client and therefore cannot be accessed remotely (but it can still access other computers remotely).

Incoming remote access is only allowed on Professional, Enterprise, and Ultimate versions of Windows. In those editions, others can remote into the computer as described above.

Something else to remember is that Remote Desktop will kick a user off if they're logged in when someone connects to that user's account remotely. This is vastly different from every other program in this list—all the others can remote in to a user account while the user is still actively using the computer.
