Previously, I wrote an article on how to secure your web surfing using some simple Unix tools. Now, we will extend that article to include securing your instant messenging using the same setup. You can pretty much secure any internet application as long as it allows you to specify a HTTP Proxy as the means to connect to the web. The theory is simple. Make a secure tunnel via your SSH client to a trusted computer running SSH server and Squid proxy server. The parameters you specify in the SSH command will create a local loopback listening service that will automatically forward your requests over to the SSH server and Squid proxy server over a secure tunnel. The information you receive back from the Squid proxy server will travel back over that same secure tunnel over to your local loopback connection and over to your internet application. More.
