How to install and use Tor for anonymous browsing or to access country-restricted content from another country

Some people want to browse the Web in complete anonymity. One tool for doing that is Tor. However, there are other reasons for using Tor. For example, when I am travelling in a country where the government blocks certain Web sites (or blocks accessing content on certain Web sites), or when I am travelling overseas and certain Web sites back home will not let me view content (e.g. TV shows), I use Tor. Note that some Web sites are now clever enough to detect that you are accessing them via a proxy and could be overseas, so even Tor will not gain you access to media on some Web sites back home. Anyway, it’s still worth trying Tor to see if it works in your case.

For an overview of the installation and configuration procedure, see Running the Tor client on Linux/BSD/Unix. Below I will explain how to install and use Tor in Gentoo Linux.

Before you use Tor, it is useful to check your current IP address. Several Web sites will tell you your current IP address; here is the site I usually use:

1. Install Tor:

# USE="tordns" emerge -1v tor

(Actually, the more-recent versions of the tor package don’t require that USE flag but I’ve left it in as it does no harm.)

2. Install Vidalia:

# cd /usr/portage/distfiles/
# wget --no-check-certificate
# USE="tor" emerge -1v vidalia

Use the current version x.y.z of the vidalia package in the package manager and

3. Install Polipo:

# emerge -1v polipo

4. Download polipo.conf

# cd /etc/polipo
# wget --no-check-certificate

Edit April 21, 2013: The above URL is now:

5. Edit it and change proxyPort = 8118 to proxyPort = 8123

6. Copy it to /etc/polipo/:

# cd /etc/polipo
# cp /etc/polipo/config /etc/polipo/config.bak
# cp polipo.conf config

7. Configure Firefox:

Edit > Preferences > Network > Settings

Manual proxy configuration:

HTTP Proxy: Port: 8123
SSL Proxy: Port 8123

SOCKS Host: Port 9051
No Proxy for:

8. Run Vidalia and then configure it:

$ vidalia &

a) Settings > Sharing

Select ‘Run as a client only’

b) Settings > Advanced

Select ‘Use TCP connection (ControlPort)’
Address: 9051

Tor Configuration File:

Data Directory:

c) Click on ‘Edit current torrc’ and make it:

# This file was generated by Tor; if you edit it, comments will not be preserved
# The old torrc file was renamed to torrc.orig.1 or similar, and Tor will ignore it
ControlPort 9051
ExitNodes {gb}
Log notice stdout
StrictNodes 1

Note that I have specified “{gb}” above so that I am perceived by Web sites to be browsing in the UK even if I am in another country. But you can use a different country code if you want Web sites to perceive you are in another country. For example, “{us}” would make it look as if you are browsing in the USA.

9. Run Polipo:

$ sudo polipo

10. Surf to to check that you are now using a Tor exit node.

11. Surf to to check that your IP address has changed.
