Tails

Tails displays a greeter when you fire up the distro. You can choose to use Tails without making any changes. But if you do, the greeter enables you to specify a password for the root user and disable MAC address spoofing which on some computers causes trouble connecting to the internet. As soon as you’re online, Tails automatically connects to the Tor network. You can click on the Tor icon in the status bar to view the circuits and streams. Once connected you can use the Torbrowser. Another anonymising network that’s occasionally pitted against Tor is I2P (Invisible Internet Project). You can access I2P from Tails by passing the i2p boot parameter on bootup. The distro will connect to the I2P network in the background. When it’s done, fire up the bundled I2P Browser, which will take you to I2P’s browser-based control panel.
