Install and test proxychains-ng (or proxychains4) in Ubuntu 14.04

To download, compile and set-up do the following:

To test the proxychain
For example using iftop. Run iftop in a second terminal window: sudo iftop Now run elinks https://ipleak.net/ and check what you see in both the elinks and iftop. You should see your real IP in the ipleak test, and iftop should show that you are directly connecting to ipleak.net as shown below:

Now do the same through proxychain:proxychains4 elinks https://ipleak.net/

And we should see that iftop shows we are connection to an entry tor node, and elinks should show are tor ID, instead of real one.
