Tunnelling Your Way Through the Government’s Metadata Retention Laws

If you happen to be fortunate enough to have access to a Unix based web server (such as an EC2 or Linode) machine) you will surprised how easy it is to safely browse the web – circumventing the Australian government’s 2 year mandatory metadata retention laws.

t_29_0You can use an SSH tunnel to use your off-site server as SOCKS Host. A SOCKS Host (or Server) is a general purpose proxy server that establishes a TCP connection to another server on behalf of a client, then routes all the traffic back and forth between the client and the server. It works for any kind of network protocol on any port. Because the connection is secure, only the client and the host can access the the data.

This is how is circumvents Government spying. The only connection your ISP can see is the initial tunnel made to the server. All the delivery of websites etc through that connection are invisible to them (and the government).

It’s tragically easy to setup, simple initiate a SSH connection with dynamic application-level port forwarding, like this:

ssh -D 12345 user@your.server.com

And then, tell your browser that you want to use a HTTP SOCKS 5 Host for proxying (Options > Advanced > Connection Settings for Firefox):

Be warned however, while your Internet traffic will be encrypted and invisible, your DNS lookups will still be public. Firefox has a setting called ‘network.proxy.socks_remote_dns’ which you can enable by browsing to the address ‘about:config’ and searching for the string above.

Lastly, be warned that browsing this way will slightly decrease speed of your browsing – but this may be a small price to pay, and may not even be noticeable.

While this is all trivial for Linux and OSX users; Windows users will need to jump through a few more hoops. This blog post inspired and references an excellent Linode Guide which covers things in more detail, and includes instructions for Windows users using Putty.
