Surfing with anonymity

Tor and JanusVM

The Tor project is devoted to provide a free censorship-less data channel in the Internet. It is composed of a growing number of transit servers. When a user wishes to initiate an anonymous connection to a server, the Tor network creates a connection highway from the client to the server using a randomly, dynamically changed group of servers that setup the connection channel.

This allows the client to surf the Internet with anonymity: The server logs will never have your actual IP on their log files, and your ISP will never know your final destination. Each connected channel is re-established every few minutes using a different route. Tor does not provide for anonymity if you login or provide personal identification to the target system, of course.

You can picture it clearly in this diagram. Using the network as a client is free. If you want to extend the network you can also offer some of your bandwidth to the network and be part of the server farm.

JanusVM is a virtual machine based on VMWare which eases the setup and installation of the software. It is also freely available through the use of VMWare's free Server Edition product.
