Question 1: What is Tor?
Tor is a connection-based low-latency anonymous communication system which
addresses many flaws in the original onion routing design. In brief, Onion Routing is a connection-oriented anonymizing communication service.
The latest information can be found at http://tor.eff.org/, or on the mailing lists, archived at http://archives.seul.org/or/talk/ or http://archives.seul.org/or/announce/.
Question 2: What is Privoxy?
Privoxy is a web proxy with advanced filtering capabilities for protecting privacy, filtering web page content, managing cookies, controlling access, and removing ads, banners, pop-ups and other obnoxious Internet junk. Privoxy has a very flexible configuration and can be customized to suit individual needs and tastes.
Question 3: Can Tor and Privoxy help those people in Communism countries?
Yes.
Question 4: How to install Tor and Privoxy?
Linux Users:
-
I can here only provide the solution to install them on Debian or Debian-based Linux distributions, such as Ubuntu, Xandros, MEPIS. I will use Ubuntu as the example.
-
For Fedora/Red Hat Linux users, maybe you can find the RPM package on their supporting websites or using YUM to install.
-
For SuSE Linux users, please use YaST2 to install them.
-
Other Linux distribution users, please search on the Internet or consulting BBS, Mail list, etc.
FreeBSD Users:
Tor and Privoxy can work on FreeBSD, you can use port to install or you can download the source to compile by yourself.
Mac OS X Users:
I know Tor and Privoxy can work on Mac OS X. But I haven’t tried.
Windows Users:
Please ask your locate help.
To install Tor and Privoxy on Ubuntu Linux, just run following command
sudo apt-get install tor privoxy
Question 5: What to do after the installation?
- Install the Firefox TorButton plug-in.
Go to this URL:
https://addons.mozilla.org/firefox/2275/
Click the “Install Now” button to install it. A windows for installation will popup. After the installation, restart Firefox. You will see a button at the right bottom of Firefox.
- Configure the Privoxy.
Open Privoxy’s “config” file (look in /etc/privoxy/ or /usr/local/etc/) and add the line
forward-socks4a / localhost:9050 .
to the top of the config file. Don’t forget to add the dot at the end.
Privoxy keeps a log file of everything passed through it. In order to stop this you will need to comment out three lines by inserting a # before the line. The three lines are:
logfile logfile
and the line
jarfile jarfile
and (on some systems) the line
debug 1 # show each GET/POST/CONNECT request
You’ll need to restart Privoxy(if you are a newbie of Linux, just reboot the computer) for the changes to take effect.
