Ubuntu Linux 12.04 LTS – World Wide VPN’s

In Windows you can get free VPN software like Anchor Free, SoftFlux and Expat Shield.
But what about Linux?

US – http://www.anchorfree.com/
US – http://www.spotflux.com/
UK – http://www.expatshield.com/

So how can we create a VPN that gives us the country IP we want?

So things we will install

  • Vidalia – Vidalia offers a graphical user interface to start and stop Tor, view its status at a glance, and monitor its bandwidth usage.
  • Tor – Tor is a connection-based low-latency anonymous communication system which addresses many flaws in the original onion routing design.
  • Privoxy – Privoxy is a non-caching web proxy with advanced filtering capabilities for enhancing privacy, modifying web page data and HTTP headers, controlling access, and removing ads and other obnoxious Internet junk.

Let’s install them on terminal (Ctrl + Alt + t)

sudo apt-add-repository ppa:ubun-tor/ppa
sudo apt-get update
sudo apt-get install tor privoxy vidalia

If you want a UK ip everytime you start Tor open Vidalia and go to “View the network”. Here you will see a bunch of relays, sort them by country and copy the nicknames of wich you want to look like the ones below.

ExitNodes TorLand2, TorLand1, TorLand5, st0nerhenge, c00psTOR, EnfluraneNode, microlah, YoureOnCCTV, hamtor
StrictExitNodes 1

Go to terminal

sudo gedit /etc/tor/torrc

Insert the lines you created save and exit.

Start tor

tor &

Go to Network GUI -> Proxy

Socks Server: 127.0.0.1
Port: 9050

If you want to logoff the VPN set proxy to none and stop tor

sudo killall tor
