HOWTO : The Onion Router (Tor) on Ubuntu 9.04

The Onion Router (Tor) allows you to surf the internet anonymously. The connection between relays and bridges are encrypted. However, you and the bridges or relays are not. The disadvantage of using Tor is the connection speed will drop a lot. You will feeling that you are using a 56K modem in the modern days.



Step 0 :



Add Tor repositories.

sudo nano /etc/apt/sources.list.d/tor.list



Copy and paste the following lines to the file.



deb http://mirror.noreply.org/pub/tor jaunty main

deb-src http://mirror.noreply.org/pub/tor jaunty main



Step 1 :



Get and install the Tor GPG key.



gpg --keyserver subkeys.pgp.net --recv 94C09C7F

gpg --fingerprint 94C09C7F

gpg --export 94C09C7F | sudo apt-key add -

sudo apt-get update

sudo apt-get upgrade



Install tor.

sudo apt-get install tor



Step 2 :



Install Privoxy.

sudo apt-get install privoxy



Edit the configure file of privoxy.

sudo nano /etc/privoxy/config



Uncomment the following line.



forward-socks4a / localhost:9050 .



Step 2a (Optional) :



If you are behind firewall or NAT as well as router, you should uncomment the following line at the configure file.



forward 192.168.*.*/ .



Step 3 :



Made sure Tor is working.



sudo /etc/init.d/privoxy start

sudo /etc/init.d/tor start



netstat -a | grep 9050



If the output is similar to the following line, your Tor is working.



tcp 0 0 localhost:9050 *:* LISTEN
