Want a complete anonymous Internet access? For free? Then TOR is the answer! TOR is the open source leader in anonymity on the Internet, and it can anonymize your online presence from instant messengers such as AIM, ICQ, MSN, Jabber, IRC, WWW and even FTP. You can also torify your shell commands such as wget, ssh, lynx, perl, apt-get and a lot more. In technical terms, TOR encrypts your data and connection through linked proxies all over the world – thereby making you secure and resistant to IP tracing.
“TOR is free software and an open network that helps you defend against a form of network surveillance that threatens personal freedom and privacy, confidential business activities and relationships, and state security known as traffic analysis” – TOR Team
TOR (The Onion Router) is an open-sourced software enabling users from Internet censored countries like China, to access the outside world without revealing their location and sensitive information. Most site plug-ins are blocked, such as flash content and cookies (the goal of this software is your privacy in the first place), but you can find a tutorial on the TOR website on how to customize the application to enable such content.
Vidalia is a graphical user interface for TOR, that runs on almost all computer platforms. Using the Vidalia interface, you can start or stop TOR, and check the bandwidth usage. It can also be used to help to the TOR network by setting up your own TOR server, making the network stable for other nearby users. The default role of the software is “act as client”. There is also a selection enabling other TOR users to browse the web in case they are blocked.
You can also use Vidalia to run a caching server such as Polipo that is best to use in combination with TOR.
And to better serve its purpose of making your browsing secure and anonymous, TOR urge its users to help each other, run relay on countries with low usage to effectively divert all possible attacks and tracing done by hackers and authorities.
