Anonymous browsing with Tor part 1

This video is courtesy emiemi2.

Tor is a software project that helps you defend against traffic analysis, a form of network surveillance that threatens personal freedom and privacy, confidential business activities and relationships, and state security. Tor protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, and it prevents the sites you visit from learning your physical location. Tor works with many of your existing applications, including web browsers, instant messaging clients, remote login, and other applications based on the TCP protocol.

Tor works by routing a user's Internet connection through a long and wholly undocumented and unlogged list of participating hosts. Theoretically, it is impossible to trace a connection back to its origin through this system. With the lack of logging, the only practical way is to monitor participating hosts and try and figure out who is doing what. The result is that anyone who uses Tor is anonymous to anyone whose services he is using. This provides the Tor user the freedom to privacy, and complete freedom from being identified.

The first part is simply about what Tor is and how it works. The second part contains step-by-step instructions for installing Tor and Privoxy on your GNU/Linux box.
