Dedication

This book is dedicated to my dear mother, who doesn’t care about internet
freedom, but only her children and grandchildren, so that I have time to
write.

This book is also dedicated to my dear motherland — China, where there is
GFW which blocks internet freedom, so that I have to write something about
how to unblock blocked sites.

Acknowledgements

Among all those free anti-censorship tools mentioned in this book, none is
created by myself, and I just test and share them and tell people how to use
them.

So, thanks to the authors who develop and share those free VPN, SSH, Proxy
and/or any other anti-censorship tools.

Preface
My Internet Freedom Declaration

Preface

While there is no definition, someone declares five basic principles of Internet Freedom, which are
Expression, Access, Openness, Innovation and Privacy.

As a man living in China, I totally agree with those 5 principles and know how import internet freedom will
be, since you might go to jail by a message you posted online, fail to visit Facebook, Twitter, YouTube and
many other websites, get your website shut down because of one criticized post, and even find out that your
private chat history were released to the police without any court document, so on and so forth.

Sounds horrible, right? But which were all happened in the Chinese internet world.

Since 2007, I have fought against the GFW (great firewall) — the biggest part of Internet Censorship in China,
by testing free anti-censorship tools as many as possible and sharing them on my blogs, both Free Nuts and
Jing Pin (in Chinese).

Up till now, I have tested and introduced over 100 free anti-censorship tools, including VPN, Proxy, SSH and
more, among which, some may be not available any more when you are reading this book, but luckily, there
will be always some new tools, and I will keep an eye on them.

Chapter Two
Free Proxy Softwares

Chapter Two
Free Proxy Softwares

Although both are proxies, desktop softwares are different from online websites.

While online proxies are full of ads, there are less or even no ads for proxy desktop softwares; while you can
use online proxies directly, you need to download and install their clients before you can use those proxy
softwares.

If the websites of those proxy softwares are blocked in your area (such as China), it is a good idea for you to
use free online proxies to visit them.

Among those free proxy softwares, the following 7 are the best:

1. Ultrasurf;

2. Freegate;

3. Tor;

4. GappProxy;

5. Goagent;

6. Hyk-proxy;

7. Snova.

9

Chapter Two
Part One: Ultrasurf

Part One: Ultrasurf

As one of the best proxy softwares, Ultrasurf is very easy to use without any installation.

The following will show you how to use it in 3 steps:

1. Download Ultrasurf

Open the Ultrasurf.us site, and click on the "FREE DOWNLOAD" button on the right top, then you can
download the Ultrasurf client as a ZIP file.

In case the Ultrasurf.us site is blocked in your area (such as China), you can use some other proxies, SSH
tunnels or VPN services to unblock it.

2. Run Ultrasurf

10

Chapter Two
Part One: Ultrasurf

After download, extract the ZIP file, then you can get an EXE file, open which, you can run Ultrasurf
directly.

In case you come across with a Windows Security Alert, such as what you can see from the following image:

11

Chapter Two
Part One: Ultrasurf

Just click on the "Allow access" button, then you can see an IE new tab of Wujie, which is the Chinese
version of Ultrasurf, and you can unblock any blocked sites right away.

3. Set browser network proxy

On IE, you can use the Ultrasurf proxy service directly after connection, but on Chrome, Firefox, Safari or
any other browser, you also need to set the network proxy to "127.0.0.1 : 9666".

Take Firefox for example, you can find the proxy settings page via the following path:

Preference –> Advanced –> Network –> Settings

Then select "Manual proxy configuration" to enter "127.0.0.1" & "9666" on the HTTP Proxy column, check
the "Use this proxy server for all protocols" box, and click the "OK" button to save the change, as what you
can see from the following image:

12

Chapter Two
Part One: Ultrasurf

Instead to set the network proxy settings manually as mentioned above, you can also check out SwitchySharp
and FoxyProxy to set them automatically.

After that, you can bypass internet censorship, encrypt online communications, and hide your IP on non-IE
browsers, too.

13

Chapter Two
Part Two: Freegate

Part Two: Freegate

Like Ultrasurf, Freegate is also a very popular and easy-to-use proxy service.

The following will show you how to use Freegate in 3 steps:

I. Download Freegate

Open the Dynaweb site and download the Freegate client software, whether in exe or zip format.

In case the Dynaweb site is blocked in your area (such as China), you can use some other proxies, SSH
tunnels or VPN services to unblock it first.

II. Run Freegate
If you downloaded the exe file, just open it, and if you downloaded the zip file, extract it and run the exe file.

When the connection is successful, you can use the Freegate proxy service right away, as what you can see
from the following image:

14

Chapter Two
Part Two: Freegate

But before you can see the control panel in the above image, you may come across the following 2 pop-up
windows:

1. Freegate Proxy Control

15

Chapter Two
Part Two: Freegate

As default, the domains of ".cn", ".baidu", ".qq" and some other suffixes will be connected directly, even
though you remove them or select "Choose All websites go through Freegate proxy", which means you can't
visit the sites of those domains with Freegate anyway.

So, you can neglect this window and just click the "OK" button to close it.

2. Windows Security Alert

In case you come across with a Windows Security Alert, such as what you can see from the following image:

16

Chapter Two
Part Two: Freegate

Just click on the "Allow access" button, then you can see the proxy's Chinese site Dongtaiwang on your IE
browser.

III. Set browser network proxy

17

Chapter Two
Part Two: Freegate

Same as Ultrasurf, On IE, you can use the Freegate proxy service directly after connection, but on Chrome,
Firefox, Safari or any other browser, you also need to set the network proxy to "127.0.0.1 : 8580".

The above instructions are for Windows only, in fact, Freegate is also available on Mac and Linux computer
operating systems, and you can refer to the FAQ page for the usages.

And besides computers, Freegate also supports Android, Java and WM mobile phones, but only in Chinese.

18

Chapter Two
Part Three: Tor

Part Three: Tor

As one of the most popular proxy softwares, Tor can be used on Windows, Mac, Linux/BSD/Unix, Android
and Nokia Maemo/N900 systems, with multiple languages supported.

The following will show you how to use its basic and most popular 2 versions — Tor Browser Bundle and
Vidalia Bundle on Windows and Mac.

1. Download Tor

On the Download page, you can choose to download the right version according to your computer systems.

For Tor Browser Bundle, you can and only can use its own browser (based on Firefox) to use its proxy
service; and for Vidalia Bundle, you can use your Firefox, Chrome, Safari or some other browsers by setting
their network proxies.

By the way, you can choose the Tor browser output language before downloading Tor Browser Bundle.

2. Run Tor

19

Chapter Two
Part Three: Tor

No matter which version you downloaded, you can extract or install the package and run the Tor service
directly.

For Tor Browser Bundle, you can run the "Start Tor Browser" (for Windows) or "TorBrowser" (for Mac)
file, and for Vidalia Bundle, you can run the "Vidalia" file.

If the onion icon turns green, then the Tor proxy is working.

3. Add bridges

20

Chapter Two
Part Three: Tor

If the onion icon doesn't turn green, then the current Tor network is blocked, and the easiest way to solve the
problem is to open the Vidalia's "Network" settings page, to select "My ISP blocks connections to the Tor
network", and to add some bridges.

So, how to get bridges for Tor? The following are 2 ways for your choice:

3.1 Via web

Visit the Bridges page, and enter the verification code, then you can get 2 bridges.

3.2 Via email

You can send an email with "get bridges" subject to "bridges@torproject.org" via your Gmail, soon you will
get three newest bridges.

21

Chapter Two
Part Three: Tor

By the way, there used to be a "Find Bridges Now" button for to you get bridges directly, as mentioned
before, but which is gone now.

4. Set browser network proxy

For Tor Browser Bundle, you can unblock the blocked site with its own browser directly, and for Vidalia
Bundle, you need to change the SOCKS proxy to "127.0.0.1 : 9050".

Take Firefox for example, you can find the proxy settings page via the following path:

Preference –> Advanced –> Network –> Settings

22

Chapter Two
Part Three: Tor

And select "Manual proxy configuration" to enter "127.0.0.1" & "9050" on the SOCKS column. By the way,
you'd better select SOCKS v4, since SOCKS v5 may be not workable.

Between Tor Browser Bundle and Vidalia Bundle, the first one is easier and more safe, but you can only use
its own browser.

23

Chapter Two
Part Four: GAppProxy


GAppProxy hasn't been updated since the 2.0.0 version in 2010, and doesn't support https well.

But as a GAE proxy, it is still available for you to surf anonymously and get access to the blocked sites.

For how to install and use GAppProxy, you can check out the following 7 steps:

1. To create a GAE application

Log in your Google App Engine account and create an available application ID, such as "freenutsdotorg"
used for this post.

2. Generate a new application-specific password

24

Chapter Two

On the "Security" page of your "Google Accounts", click the "Edit" button of "Authorizing applications and
sites", and generate a new application-specific password.

But you can skip this step if you do not use 2-step verification for your Gmail account.

3. Download GAppProxy

On the GAppProxy Downloads page, you can download the packages according to your operating systems.

3.1 Download the Windows packages

To run GAppProxy on Windows, you need to download the following 2 packages:

uploader-2.0.0-win.zip
localproxy-2.0.0-win.zip

25

Chapter Two

After download, you can extract them and get the following 2 folders:

uploader-2.0.0-win
localproxy-2.0.0-win

3.2 Download the Mac/Linux packages

And to run GAppProxy on Mac/Linux, you need to download the following 2 packages instead:

fetchserver-2.0.0.zip
localproxy-2.0.0.tar.gz

Extract the packages, then you can get the following 2 folders:

fetchserver-2.0.0
localproxy-2.0.0

4. Edit the app.yaml file

On Windows, you can find the app.yaml file in the "fetchserver" directory of the "uploader-2.0.0-win" folder;
and on Mac/Linux, you can find the app.yaml file in the "fetchserver-2.0.0" folder.

After that, open the app.yaml file, and change the "your_application_name" to your GAE app ID created in

26

Chapter Two

step 1.

5. Upload the GAppProxy server
5.1 How to upload the GAppProxy server on Windows

Open the "uploader-2.0.0-win" folder, double-click the "uploader.exe" file, and enter your App ID, Gmail
address and password, then you are done.

5.2 How to upload the GAppProxy server on Mac/Linux

27

Chapter Two

To upload the GAppProxy server on Mac/Linux, we need a third-party tool.

5.2.1 Download Google App Engine SDK for Python

Download Google App Engine SDK for Python of Mac or Linux version, and install it.

5.2.2 Add new application

Run GoogleAppEngineLauncher, click "New Application" in the "File" option on the top menu bar, enter
your GAE app ID as "Application Name", and assign a folder as "Application Directory", or just use the
default one it offers.

5.2.3 Move the server files

Copy "app.yaml" and "fetch.py" files in the "fetchserver" folder and paste them into the "Application
Diretory" folder.

5.2.4 Upload the server

Back to GoogleAppEngineLauncher, click on the "Deploy" button, enter your Gmail address and password,
then you can upload the GAppProxy server to GAE.

28

Chapter Two

5.3 Test the GAppProxy server

Open your browser, and enter the following URL:

http://APP_ID.appspot.com/fetch.py

Remember to replace "APP_ID" with your own GAE app ID, and if you can see the following result:

Then the GAppProxy server is uploaded successfully, if not, you can try to change "http" to "https", or to run
an anti-censorship tool (such as proxy, ssh or VPN), and try again, if still not, then you need to upload the
server again.

6. Run the GAppProxy client
When the server is uploaded successfully, you can run the GAppProxy on your computer.

6.1 How to run the GAppProxy client on Windows

For Windows, there is an executive application, clicking on which, you can run the GAppProxy, but you
need to edit the "proxy.conf" file first.

6.1.1 Edit the proxy.conf file

Open the "proxy.conf" file in the "localproxy-2.0.0-win" folder, edit the last line by changing
"your-fetch-server" to your GAE app ID, and deleting the "#" mark, as what you can see from the following
image:

29

Chapter Two

After that, save the file.

6.1.2 Run the GAppProxy client

You can double-click the "proxy.exe" file in the same folder to run the GAppProxy client.

6.2 How to run the GAppProxy client on Mac/Linux

On Mac/Linux, you can use the Terminal application to run the GAppProxy client, but you also need to edit
the "proxy.conf" file first.

6.2.1 Edit the proxy.conf file

Same as what you do on Windows, but the "proxy.conf" file is located in the "localproxy-2.0.0" folder.

6.2.2 Run the GAppProxy client

30

Chapter Two

Open the Terminal application, and enter the following command line:

python xxx/localproxy-2.0.0/proxy.py

Remember to replace "xxx" with the full path to the "localproxy-2.0.0" directory, or you can just drag the
"proxy.py" file and drop it behind "python".

7. Edit the browser proxies

31

Chapter Two

When the GAppProxy client is running, you can edit the browser network settings and change the proxy
address to "127.0.0.1: 8000", as what you need to do with any proxy service.

By the way, since GAppProxy only supports HTTP with 80 port and HTTPS with 443 port, you can leave the
SOCKS and FTP proxies empty.

Note:
Take the "freenutsdotorg" app ID for example, if you can't open the site of the following URL on your
browser:

http://freenutsdotorg.appspot.com/

32

Chapter Two

But you can do that after changing "http" to "https", then you need to make the same change for the
"fetch_server" link in the last line of the "proxy.conf" file, such as the following:

fetch-server = https://freenutsdotorg.appspot.com/fetch.py

And if you still fail to open the site after changing "http" to "https", then your app ID is blocked and you
won't be able to use the GAppProxy service, in that case, you can create a new GAE app and try again.

33

Chapter Two
Part Five: Goagent

Part Five: Goagent

Like GAppProxy, Goagent is also a GAE proxy.

And for how to use Goagent, you can refer to its official site in Chinese, or you can check out the following 7
steps for an easier reference in English:

1. Create GAE applications

Goagent supports multiple app IDs, so that you can creat one or more new GAE applications, or use the old
ones, but the "Storage Scheme" of each must be "High Replication".

2. Generate new application-specific password

34

Chapter Two
Part Five: Goagent

sites", and generate a new application-specific password, which will be used when uploading the Goagent
server to your GAE in step 4.


3. Download the Goagent packapge

Download the Goagent package (a zip file) via the link on the top of its homepage, as what you can see from
the above image.

After that, extract the zip file, and you will get a "local" folder as well as a "server" folder.

4. Upload the Goagent server
Open the "server" folder, and upload the Goagent server to your GAE in the following ways:

35

Chapter Two
Part Five: Goagent

4.1 How to upload the Goagent server on Windows

On Windows, open the "uploader.bat" file, enter your GAE app ID created in step 1, your Gmail address and
the application-specific password, then you can start to upload.

And to use more than one app ID, you can separate them with the "|" mark.

4.2 How to upload the Goagent server on Mac

36

Chapter Two
Part Five: Goagent

On mac, open the Terminal application, and enter the following command line:

cd the-path-to-the-server-folder

Such as the following:

cd /Users/air/Downloads/goagent-goagent-80e5f01 3/server

You can also just drag the "server" folder and drop it behind the "cd" command.

After that, enter the following command line:

python uploader.zip

Then, you can enter your App IDs, Gmail address and the application-specific password to upload the server.

By the way, do not bypass the first command line and use the "python the-path-to-uploader.zip" command
directly, which may be not workable.

5. Change the proxy.ini file

37

Chapter Two
Part Five: Goagent

When the upload is finished, open the "proxy.ini" file in the "local" folder, and change the "appid" value
from "goagent" to your real GAE application IDs.

By the way, you can also change the "profile" value from "google_cn" to "google_hk" for a better security
with https mode.

6. Run the Goagent client
After saving the "proxy.ini" file, you can start to run Goagent.

6.1 How to run the Goagent client on Windows

38

Chapter Two
Part Five: Goagent

On Windows, you can just double-click on the "Goagent.exe" file in the "local" folder and run the proxy
service.

6.2 How to run the Goagent client on Mac

On Mac, you can open the Terminal application and enter the following command line:

python the-parth-to-proxy.py

39

Chapter Two
Part Five: Goagent

This time, you can drag the "proxy.py" file from the "local" folder and drop it behind the "python" command.


When the Goagent client is running, you can edit the browser network settings and change the proxy address
to "127.0.0.1: 8087", as what you need to do with any proxy service.

After that, you can start to use Goagent to browse the internet anonymously and unblock the blocked sites in
your area.

But, same as GAppProxy and Hyk-proxy, the Goagent proxy doesn't support https well, even though that you
can double-click the "CA.crt" file in the "local" folder to install or import the certification, which will only

40

Chapter Two
Part Five: Goagent

work on Safari, but not Chrome or Firefox during my test for Twitter and Facebook.

By the way, besides Windows and Mac systems mentioned above, Goagent is also available for Linux, as
well as Android, iOS, webOS, OpenWRT and Maemo operating systems.

41

Chapter Two
Part Six: Hyk-proxy

Part Six: Hyk-proxy

Same as GAppProxy, the Hyk-proxy GAE service won't be updated any more, but it is still workable.

For how to install and use Hyk-proxy on Windows and Mac/Linux systems, you can check out the following
8 steps for complete instructions:

1. Create a GAE application

Sign in your GAE account and create an application ID which is available.


42

Chapter Two
Part Six: Hyk-proxy



3. Download Java and Google App Engine SDK for Java

If you haven't gotten these two softwares on hand as mentioned before, you can download Java on its official
website, and download Google App Engine SDK for Java from Google Code.

By the way, on Mac, you only need to download and extract the Google App Engine SDK for Java package,
since Java is pre-installed.

4. Download the Hyk-proxy packages

43

Chapter Two
Part Six: Hyk-proxy

Among the 4 packages on the Hyk-proxy Downloads webpage, you can just download
"hyk-proxy-0.9.4.1.zip" and "hyk-proxy-gae-server-0.9.4.1.zip".

By the way, on Windows, you can also download "hyk-proxy-install_0.9.4.1.exe" instead of
"hyk-proxy-0.9.4.1.zip"; and you need to download the "hyk-proxy-android-0.9.4beta.apk" package if you
want to use Hyk-proxy on your Android.

After that, extract the zip files you download.

5. Deploy task
To deploy task means to upload the Hyk-proxy server to your GAE application.

On Windows, you can run the "install.bat" file in the "hyk-proxy-gae-server-0.9.4.1" folder; and on
Mac/Linux, you can open the Terminal application and enter the following command line:

sh /the-path-to/install.sh

Or you can just drag the "install.sh" file from the "hyk-proxy-gae-server-0.9.4.1" folder and drop it behind
the "sh" command.

After that, you can see an "AppEngine AppCfg GUI Wrapper" window, such as the following:

44

Chapter Two
Part Six: Hyk-proxy

In the window, you can define the location of the "Google App Engine SDK for Java" folder, enter your
GAE app ID, select the "hyk-proxy-gae-server-0.9.4.1" folder as AppLocation, enter your Gmail address and
password, then you can click the "Deploy" button to upload the Hyk-proxy server to your GAE.

P.S.

By the way, if you fail to deploy the task for the following error:

Bad configuration: appengine-web.xml does not contain a <threadsafe> element.

45

Chapter Two
Part Six: Hyk-proxy

Then you need to enter the following line into the "appengine-web.xml" file:

<threadsafe>true</threadsafe>

Such as what you can see from the following image:

6. Add GAE application ID to Hyk-proxy client
On Windows, you can double-click the "startgui.bat" file in the "bin" folder, or run "Start hyk-proxy (GUI)"
if you have installed "hyk-proxy-install_0.9.4.1.exe"; and on Mac/Linux, you can open the Terminal
application and enter the following command line:

sh /the-path-to/startgui.sh

46

Chapter Two
Part Six: Hyk-proxy

Or you can just drag the "startgui.sh" file from the "hyk-proxy-0.9.4.1" folder and drop it behind the "sh"
command.

After that, you can open the Hyk-proxy client window, click on the "Config" button of "GAE 0.9.4.1" in the
"Plugins" tab, and click the "New" button to add your APP ID, such as what you can see from the following
image:

And you can add more than one App ID, after that, click the "Apply" button.

7. Start Hyk-proxy

47

Chapter Two
Part Six: Hyk-proxy

When the App IDs are added, you can click the "Start" button to connect to the Hyk-proxy service.

When the Hyk-proxy fetch service is working, configure your browsers http proxy to below address:

127.0.0.1: 48100


48

Chapter Two
Part Six: Hyk-proxy

The above screenshot is for Firefox, and for other browsers, the http proxy settings may be a little different.

That's all, and you can surf the internet anonymously and get access to the blocked sites.

Bonus:
Hyk-proxy will not work when your GAE application ID is blocked, in that case, you can connect Hyk-proxy
with XMPP.

49

Chapter Two
Part Six: Hyk-proxy

To do so, you can open the "Connection" tab of the GAE plugin "Config" window, select "XMPP" as the
connection mode and add your XMPP account (such as GTalk).

Besides, you can also connect Hyk-proxy with HTTPS mode or HTTP proxy, but XMPP is the fastest and
best.

50

Chapter Two
Part Seven: Snova

Part Seven: Snova

Among GAppProxy, Goagent, Hyk-proxy and Snova these 4 popular GAE proxies, Snova is the best, since it
supports HTTPS well.

Besides, it is also available for you to use in the following 6 different ways.

1. To use Snova directly

As default, Snova can automatically connect to some random GAE apps shared by others, so that you can
just download the Snova client and run it.

2. To use Snova on your own GAE app

51

Chapter Two
Part Seven: Snova

Instead to use others' apps, you can also create your own ones, and upload the Snova server to them to run
the proxy service.

Again, none of the above 2 ways are available for you to visit HTTPS links, and to do so, you need install the
C4 plugins on any of the following 4 PaaS platforms:

3. To use Snova on Cloud Foundry

52

Chapter Two
Part Seven: Snova

Cloud Foundry is available for you to run the Snova c4 plugin in an instance with 4-core CPU, 2 G disk, and
512M memory, no bandwidth limit.

4. To use Snova on Heroku

53

Chapter Two
Part Seven: Snova

The network bandwidth limit of Heroku is 2TB/month.

5. To use Snova on OpenShift

OpenShift is available for you to create up to 3 apps, and each of which will run in an instance of 1GB disk
and 512MB memory.

6. To use Snova on Jelastic

54

Chapter Two
Part Seven: Snova

With Jelastic, you can choose to build your C4 plugin on Servint, Dogado, Rusonyx or some other hosted
service provider, and deploy the c4 plugin on its website directly without entering any command lines.

For the C4 plugins, you need to use the "snova-c4-heroku-server-xxx.zip" file on Heroku, and use the
"snova-c4-server-xxx.zip" file on the other 3 PaaS platforms.

By the way, besides to use Snova on GAE, Cloud Foundry, Heroku, OpenShift or Jelastic separately, you can
also use on one, more or even all of them together, as well as to use multiple apps on each of them.

55

Chapter Two
Part Seven Section One: The Easiest Ways To Use Snova


Whether Hyk-proxy, Goagent, Snova or any other GAE proxy, you need to deploy their servers to your GAE
apps before you can use them as mentioned before.

But it may be even hard for someone to create an account on GAE, and which is not available in Iran at all.

In that case, you can use Hyk-proxy and Snova according to the following ways directly with the default
GAE apps shared by others:

1. The easiest ways to use Hyk-proxy

On the Hyk-proxy Downloads page, you can download "hyk-proxy-0.9.4.1.zip" or
"hyk-proxy-install_0.9.4.1.exe" (for Windows only), and extract or install to use the proxy service on
Windows and/or Mac.

1.1 On Windows

On Windows, you can double-click the "startgui.bat" file in the "bin" directory of the extracted folder
"hyk-proxy-0.9.4.1", or run "Start hyk-proxy (GUI)" if you have installed "hyk-proxy-install_0.9.4.1.exe".

1.2 On Mac


56

Chapter Two


Or you can just drag the "startgui.sh" file from the "hyk-proxy-0.9.4.1" and drop it behind the "sh" command.

Whichever way you are using, you can open the Hyk-proxy client, click on the "Start" button, and run the
proxy service.

2. The easiest ways to use Snova

Which will be nearly same as what you do with Hyk-proxy.

On the Snova Downloads webpage, you can just download and extract "snova-xxx.zip" to use the proxy
service on Windows and/or Mac.

2.1 On Windows

On Windows, you can double-click the "startgui.bat" file in the "bin" directory of the "snova-xxx" folder.

2.2 On Mac

57

Chapter Two



Or you can just drag the "startgui.sh" file from the "snova-xxx" folder and drop it behind the "sh" command.

Whichever way you are using, you can open the Snova client, click on the "Start" button, and run the proxy
service.

By the way, the above direct ways are not available for GAppProxy or Goagent, since the GAppProxy's
default GAE app "fetchserver1" is over its serving quota, and Goagent does not offer a default GAE app at
all.

58

Chapter Two
Part Seven Section Two: How To Use Snova On GAE


As mentioned before, the Hyk-proxy GAE service won't be updated any more, since the developer stops to
work on a new project — Snova.

Similar to Hyk-proxy, Snova is also a web proxy based on GAE, but it works for HTTPS very well, when
running on CloudFoundry, Heroku, OpenShift and some other PaaS (Platform as a service) platforms.

The following will show you how to install and use Snova on GAE, which are nearly same as what you do
with Hyk-proxy.

1. Create a GAE application

Sign in your GAE account and create an application ID which is available.


59

Chapter Two



3. Download Java and Google App Engine SDK for Java

If you haven't gotten these two softwares on hand as mentioned before, you can download Java on its official
website, and download Google App Engine SDK for Java from Google Code.

By the way, on Mac, you only need to download and extract the Google App Engine SDK for Java package,
since Java is pre-installed.

What is more, besides Java, Snova also supports the Go language, so that you can download Go and Google
App Engine SDK for Go instead.

60

Chapter Two

4. Download the Snova packages

Among the 7 packages on the Snova Downloads webpage, you can just download "snova-xxx.zip" and
"snova-gae-jserver-xx.zip" for Java.

After that, extract the zip files you download.

5. Deploy task
Like Hyk-proxy, on Windows, you can run the "install.bat" file in the "snova-gae-jserver-xx" folder; and on
Mac/Linux, you can open the Terminal application and enter the following command line:

sh /the-path-to/install.sh

Or you can just drag the "install.sh" file from the "snova-gae-jserver-xx" folder and drop it behind the "sh"
command.

After that, you can see an "AppEngine AppCfg GUI Wrapper" window, such as the following:

61

Chapter Two

In the window, you can define the location of the "Google App Engine SDK for Java" folder, enter your
GAE app ID, select the "snova-gae-jserver-xx" folder as AppLocation, enter your Gmail address and
password, then you can click the "Deploy" button to upload the Snova server to your GAE.

6. Add GAE application ID to the Snova client
On Windows, you can double-click the "startgui.bat" file in the "bin" folder; and on Mac/Linux, you can
open the Terminal application and enter the following command line:


62

Chapter Two

Or you can just drag the "startgui.sh" file from the "snova-xxx" folder and drop it behind the "sh" command.

After that, you can open the snova client window, click on the "Config" button of "GAE xxx" in the
"Plugins" tab, and click the "New" button to add your APP ID, such as what you can see from the following
image:

And you can add more than one App ID, after that, click the "Apply" button.

7. Start Snova

63

Chapter Two

When the App IDs are added, you can click the "Start" button to connect to the Snova server.

Like Hyk-proxy, when the Snova service is running, you also need to configure your browsers http proxy to
below address:

127.0.0.1: 48100


64

Chapter Two

The above screenshot is for Firefox, and for other browsers, the http proxy settings may be a little different.

That's all, and you can surf the internet anonymously and get access to the blocked sites.

But same as Hyk-proxy, Snova running on GAE still does NOT work for HTTPS links, until you run it on
CloudFoundry, Heroku, OpenShift and/or some other PaaS platforms, which will be introduced later, stay
tuned.

65

Chapter Two
Part Seven Section Three: How To Use Snova On Cloud Foundry


As mentioned before, Snova still does NOT work for HTTPS, until you run it on Cloud Foundry, Heroku,
OpenShift and/or some other PaaS platforms.

So, the following will show you how to install and use Snova on Cloud Foundry with 7 easy steps:

1. Create a Cloud Foundry account

On the Cloud Foundry signup page, enter your email address to request a invite, which will be sent to your
Inbox with login username and password soon.

cd /the-parth-to/snova-c4-server

You can also just drag the "snova-c4-server" folder and drop it behind the "cd" command.

After that, you can start to configure and deploy the Snova c4 server to Cloud Foundry by entering the
following command lines one by one:

vmc target api.cloudfoundry.com
vmc login (To enter your Cloud Foundry username and password)
vmc push free-nuts (To replace free-nuts with any name you like for the Cloud Foundry app)
Would you like to deploy from the current directory? [Yn]: (To enter y)

Then you have successfully deployed the Snova server to Cloud Foundry.

5. Configure the Snova c4 client

70

Chapter Two

Find and open the "c4-client.conf" file via the following path:

.../snova-xxx/plugins/c4/conf/c4-client.conf

And uncomment the "WorkerNode [1]" line by changing "xyz" to your Cloud Foundry app name.

6. Configure snova.conf

71

Chapter Two

Find and open the "snova.conf" file via the following path:

.../snova-xxx/conf/snova.conf

And change the "ProxyService" value from "GAE" to "C4".

7. Start Snova

72

Chapter Two

After that, you can start Snova, and if you can see the following message:

Start plugin:C4 … Success

Then you can visit the HTTPS links normally.

73

Chapter Two
Part Seven Section Four: How To Use Snova On Heroku


In the last post, we have learned how to install and use Snova on Cloud Foundry, this post will show you
how to do that on Heroku.

Since Heroku is also a PaaS platform, the steps will like what you do on Cloud Foundry, as what you can see
from the following:

1. Create a Heroku account

On this Heroku page, enter your email address and sign up an account.

2. Install Heroku Toolbelt

74

Chapter Two

After signup, you can receive an email, click the long confirmation link inside, download the Heroku
Toolbelt app and install it on your computer.

3. Download snova-c4-heroku-server-xxx.zip

On the Snova Downloads webpage, download the "snova-c4-heroku-server-xxx.zip" file and extract it.

4. Deploy Snova c4 server to Heroku

75

Chapter Two


cd /the-parth-to/snova-c4-heroku-server-xxx

You can also just drag the "snova-c4-heroku-server-xxx" folder and drop it behind the "cd" command.

After that, you can start to configure and deploy the Snova c4 server to Heroku by entering the following
command lines one by one:

heroku login (To enter your Heroku account email and password)
git init
git add .
git commit -m "init"
heroku create --stack cedar
git push heroku master

At the end of the results, you can find a random URL like the following:

http://obscure-tundra-1542.herokuapp.com/

76

Chapter Two

Visit the page of the URL, and if you can see something like the following:

Welcome to snova-c4 server xxx!

Then you have successfully deployed the Snova server to Heroku.


Find and open the "c4-client.conf" file via the following path:


And uncomment the first "WorkerNode [0]" line by changing "xyz" to what you get in Step 4 (such as
"obscure-tundra-1542").

77

Chapter Two





7. Start Snova

78

Chapter Two



Then you can visit the HTTPS links normally.

79

Chapter Two
Part Seven Section Five: How To Use Snova On OpenShift


To install and use Snova, you can check out this post for GAE, this one for Cloud Foundry and this one for
Heroku.

The following will show you how to install and use Snova on OpenShift, another PaaS platform like the
above 3 mentioned.

1. Create an OpenShift account

On the signup page of OpenShift, you can enter your email address, password and the CAPTCHA code to
create an account.


80

Chapter Two

On the Snova Downloads webpage, download the "snova-c4-server-xxx.war" file and put it into a new empty
folder, such as "openshift" used for the following steps.

3. Install rhc

On Mac, you can install rhc with the following command line:

sudo gem install rhc

On Windows and Linux, you can check out the official page for the instructions.

81

Chapter Two

4. Deploy Snova c4 server to OpenShift

On the Terminal application, you can enter the openshift folder with the command line:

cd /the-parth-to/openshift

Or you can just drag the "openshift" folder and drop it behind the "cd" command.

After that, you can start to configure and deploy the Snova c4 server to OpenShift by entering the following
command lines one by one:

Command line 1:

rhc domain create -n freenutsdot -l xxx@gmail.com -p 123456

(To create a sub domain "freenutsdot.rhcloud.com" for your OpenShift account. Remember to change
"freenutsdot" to any name you like, to change "xxx@gmail.com" to your registered email address and to
change "123456" to your OpenShift password. )

Command line 2:

82

Chapter Two

rhc app create -a fn -t jbossas-7 -p 123456

(To create an app, which name will be used before the domain created above. Remember to change "fn" to
any name you like, and to change "123456" to your OpenShift password, then you can get a folder with the
same name of the app (such as "fn") in your current directory (such as "openshift").

Command line 3:

cd fn

(To conduct commands in the app folder created above.)

Command line 4:

mv ../snova-c4-server-xxx.war deployments/ROOT.war

(To move the "snova-c4-server-xxx.war" file into the "deployments" directory of the "fn" folder and rename
it to "ROOT.war".)

Command line 5:

git rm -r src pom.xml

(To delete the src folder and the pom.xml file.)

Command line 6:

git init

83

Chapter Two

(To reinitialize the app.)

Command line 7:

git add .

(To add the ROOT.war mode.)

Command line 8:

git commit -a -m "haha"

(To confirm and see the changes, you can replace "haha" with any message you like.)

Command line 9:

git push

(To upload the ROOT.war file to your OpenShift app.)

If no error appears, you can visit the page of the following URL:

http://fn-freenutsdot.rhcloud.com/

Remember to replace "fn-freenutsdot" with your app name and sub domain.

And if you can see something like the following:

Welcom to snova-c4 server xxx!

84

Chapter Two

(Welcom is a typo, which should be Welcome.)

Then you have successfully deployed the Snova server to OpenShift.


Supposing that you have installed Snova on GAE as mentioned before, then you can find and open the
"c4-client.conf" file via the following path:


85

Chapter Two

And enter your OpenShift app domain (such as "fn-freenutsdot.rhcloud.com") at the end line of
"WorkerNode [0]".

By the way, Snova supports multiple c4 plugins together, so that you can also add the domains of your Cloud
Foundry and/or Heroku apps in the same "c4-client.conf" file, just make sure the numbers behind
"WorkerNode" are different from each other.





By the way, you can skip this step if you have ever done this before.

7. Start Snova

86

Chapter Two



Then you can visit the HTTPS links normally, as what you can do with the Cloud Foundry or Heroku
plugins.

87

Chapter Two
Part Seven Section Six: How To Use Snova On Jelastic


As mentioned before, you can run the Snova proxy on Cloud Foundry, Heroku, OpenShift and Jelastic PaaS
platforms, with the C4 plugins.

Among these 4 PaaS platforms, Jelastic is the easiest way to install the C4 plugin, since you do NOT need to
use any command lines, as what you can see from the following detailed steps:


On the Snova Downloads webpage, download the "snova-c4-server-xxx.war" file, and you can skip this step
if which you have done before.

2. Create a Jelastic account

88

Chapter Two

On the Jelastic homepage, enter your email address to sign up an account, which login username and
password will be emailed to you soon.

3. Create your Jelastic app domain

89

Chapter Two

After login, you can see an "Environment topology" window, on which, you can enter an "Environment
name" (such as "freenuts"), which will generate you one Jelastic app domain (such as
"freenuts.jelastic.servint.net"), and then click the "Create" button.

4. Upload snova-c4-server-xxx.war

Click the "Upload" button, and browse to upload the "snova-c4-server-xxx.war" file you downloaded.

By the way, you can enter anything into the "Comment" box if you like.

5. Deploy Snova c4 server to Jelastic

90

Chapter Two

Moving the cursor over the name of the uploaded "snova-c4-server-xxx.war" file, you can see a yellow icon,
clicking on which, you can see the Environment name, clicking on which, you can see a pop-up window, and
clicking on its "Deploy" button directly without changing anything, then you can deploy the C4 plugin to
Jelastic.


91

Chapter Two

Supposing that you have installed Snova on GAE as mentioned before, then you can find and open the
"c4-client.conf" file via the following path:


And enter your Jelastic app domain (such as "freenuts.jelastic.servint.net") at the end line of "WorkerNode
[0]".

By the way, Snova supports multiple c4 plugins together, so that you can also add the domains of your Cloud
Foundry, Heroku, and/or OpenShift apps in the same "c4-client.conf" file, just make sure the numbers behind
"WorkerNode" are different from each other.

92

Chapter Two





By the way, you can skip this step if you have ever done this before.

8. Start Snova

93

Chapter Two



Then you can visit the HTTPS links normally, as what you can do with the Cloud Foundry, Heroku and/or
OpenShift plugins.

94

Chapter Two
Part Eight: Best 2 Extensions For You To Manage Network Proxy Settings


Whether Freegate, Tor, Snova or any other proxy clients or SSH tunnels, you need to change the network
proxy settings before you can use them to unblock those blocked sites.

Although their proxy addresses are same (127.0.0.1), their ports are usually different, for example, Freegate
is 8580, Tor is 9050, Snova is 48100, etc., instead to change the port value manually every time when
transferring one proxy to another, you can use the following 2 free extensions to do that automatically.

1. SwitchySharp

SwitchySharp (or Proxy SwitchySharp) is a Chrome extension.

After installation, you can see a new tab of SwitchySharp Options, on which, you can enter a proxy's name as
the Profile Name, and set the Manual Configuration.

For FreeGate, GappProxy, Goagent, Hyk-proxy, Snova or UltraSurf, you can enter 127.0.0.1 together with its
port in the HTTP Proxy column and check the "Use the same proxy server for all protocols" box; for Tor or
SSH, you can just enter 127.0.0.1 together with port 9050 or 7070 in the SOCKS Hosts (SOCKS v4) column.

95

Chapter Two

After that, click the "Save" button, then, you can click on the SwitchySharp icon in the Toolbar, and select
the Profile Name to use the proxy service.

Bonus:

To find an alternative Chrome extension, you can check out Proxy Switchy, which is nearly same as
SwitchySharp, but not so popular.

2. FoxyProxy Standard

FoxyProxy Standard is a Firefox extension.

After installation, you can see the extension icon in both Navigation Toolbar and Add-on Bar, click on
which, you can start to add proxy configuration by clicking on the "Add New Proxy" button in the settings
window.

For FreeGate, GappProxy, Goagent, Hyk-proxy, Snova or UltraSurf, you can enter 127.0.0.1 together with its
port in the Host or IP Address column of the Proxy Details tab.

And for Tor or SSH tunnel, you also need to check the "SOCKS proxy?" box as well as the "SOCKS v4/4a"
box.

For better experience, you can enter the proxy service's name as Proxy Name in the General tab if you like.

After that, click the "OK" button, then you will see a new pop-up with the following message:

96

Chapter Two

You didn't enter and enable any whitelisted (inclusive) URL patterns. This means the proxy won't be
used unless FoxyProxy is set to "Use Proxy tor for all URLs". Continue anyway?

Just click on the "OK" button, then you can select the proxy name from the "Select Mode" column in the top
of the settings window and use its proxy service.

Bonus:

AutoProxy is also a free Firefox add-on like FoxyProxy Standard.

By the way, whichever extension you are using, you can add some rules to or not to visit some sites via proxy
if you like, and then FoxyProxy Standard won't ask you if to "Continue anyway?" any more.

Free VPN Services

Chapter Three
Free VPN Services

While proxy can be taken as a carrier, who helps delivery your message to another person, VPN (Virtual
Private Network) will be like the person's office staff, who also helps you delivery your message to that
person.

While proxy only works for the application you assign to, and basically the browsers only, VPN will works
for your entire device, whether browsers, email clients, app stores or any other application that connects to
the internet.

While you need to set the browser HTTP proxy addresses to use a proxy service, you don't need to do that
with VPN services.

So, generally speaking, VPN is safer than Proxy.

Chapter Three
Part One: Free PPTP VPN Services


As one of the methods to implement VPN, PPTP (Point-to-Point Tunneling Protocol) is very easy to build
and use.

But hosting is expensive, so that there are not so many free PPTP VPN services, among which, the following
10 are the best up till now:

1. SecurityKISS

On any download page of the SecurityKISS website, you can enter your email address and get 2 PPTP/L2TP
VPN accounts in your Inbox, one is from USA, the other is from UK.

Besides, you can also sign in your SecurityKISS account with the username and password received to get

99

Chapter Three

more VPN servers from USA, UK, France and/or some other countries.

And besides PPTP/L2TP, SecurityKISS also offers free OpenVPN services for Windows, Mac/Linux
systems.

By the way, no matter which or how many VPN services you are using, the free traffic data is up to 300 MB
per day.

2. Super Free VPN

Open the Super Free VPN website, you can see the account, which server and username are fixed, while
password will be changed in up to 8 hours.

By the way, in case the "superfreevpn.com" domain is blocked in your area (such as China), you can change
it to the following IP address:

69.60.121.29

3. JustFreeVPN

100

Chapter Three

Open the JustFreeVPN website, you can see 3 free PPTP VPN accounts, one is from USA, one is from UK,
and one is from CA.

For different accounts, their servers are different, usernames are all "justfreevpn", and passwords will be

Part Three: How To Build A VPN


Want to build your own VPN instead to use others', whether free or not?

If you've already had a VPS, cloud computing or dedicated server, and the Terminal application of Mac, or
the Putty tool for Windows, you can start to build VPN services, whether PPTP, L2TP or OpenVPN types.

The following will show you how to build a PPTP, L2TP and OpenVPN on a VPS based on the Mac
Terminal application in 3 separate posts.

First of all, run your Terminal, and enter the following command:

ssh root@xxx.xxx.xxx.xxx
Just replace "xxx.xxx.xxx.xxx" with your VPS' IP, such as "178.18.17.212".

Then you will see the following message:

Are you sure you want to continue connecting (yes/no)?

Enter "yes" and press the "Return" key, then, enter your password and press the "Return" key.

P.S.:

If you've rebuilt your VPS, you may meet the following error:

Host key verification failed.

In that case, enter the following command at first:

113

Chapter Three

ssh-keygen -R xxx.xxx.xxx.xxx

Remember to replace "xxx.xxx.xxx.xxx" with your VPS' IP address.

After that, you can start to build your own VPN.

114

2. Edit the VPN interface IP addresses

Open the pptpd.conf file with the following code:

nano /etc/pptpd.conf

Press the Enter key, find and uncomment the following 2 lines:

115

Chapter Three

#localip 192.168.0.1
#remoteip 192.168.0.234-238,192.168.0.245

3. Edit DNS addresses

Enter the following command:

nano /etc/ppp/pptpd-options

Find the following codes:

#ms-dns 10.0.0.1
#ms-dns 10.0.0.2

And change them to the following ones:

#net.ipv4.ip_forward=1

6. Apply the forward

Your forward change won't be active immediately, and you need to apply it with the following commend:

sysctl -p

If everything is correct, then you can see the following result:

net.ipv4.ip_forward = 1

117

proxyarp
lcp-echo-interval 30
lcp-echo-failure 4

123

Chapter Three

After that, open the chap-secrets file:

vi /etc/ppp/chap-secrets

And insert the following content:

username l2tpd password *

For example:

freenuts l2tpd 123456 *

Then, restart L2TP:

service xl2tpd restart

5. IP forward


vi /etc/sysctl.conf

Press the "Return" key, find the line of "#net.ipv4.ip_forward=1" and uncomment it.

After that, enter the following command:

124

After that, enter the following command:


6. For reboot

Now, you can connect your L2TP/IPSec VPN, but if you reboot your VPS, your forwarding settings will be
gone, to avoid this, you can enter the following command:

vi /etc/rc.local

Press the "Return" key and paste the following contents before the "exit 0" line:

for each in /proc/sys/net/ipv4/conf/*
do
echo 0 > $each/accept_redirects
echo 0 > $each/send_redirects
done
/etc/init.d/ipsec restart

Save it, then you are done.
