How to Set up SSH SOCKS Tunnel for Private Browsing in Windows

There are many times you want to secretly search the internet, access geo-restricted information, or circumvent any interim firewalls that your network may implement.

One choice is to use a Proxy server, but this includes downloading client software on your computer and establishing the own private VPN (Virtual Private Server) or subscribing to a VPN program.

The other safer option is to redirect the local network traffic into an encrypted SOCKS proxy gateway. By using this approach, all the proxy programs will link to the SSH (Secure shell) API, and the API (Application Programming Interface) will forward all traffic towards its final destination. Your Internet Service Provider (ISP) and other third parties will not be able to examine your traffic and restrict your links to websites.

In this tutorial, we will initiate the process of building an encrypted SSH tunnel and configuring Google Chrome and Firefox web browsers to use SOCKS proxy.

What is SSH SOCKS Tunnel

SSH SOCKS Proxy functions have the same working functionality as a VPN that you might use to anonymously tunnel network traffic from your local computer to the remote SSH server. SSH tunneling is a way of transmitting arbitrary networking information over to an encrypted SSH link. It can be used to apply protection to legacy software. It can also be used to introduce VPNs (Virtual Private Networks) and to navigate intranet resources through firewalls.

SSH is a norm for safe remote login and file transfer over untrusted networks. It also offers a way to control the data traffic of any given program using port forwarding, practically tunneling any TCP/IP connexion over SSH. This ensures that the data traffic of the application is directed to flow within the secured SSH link such that it cannot be eavesdropped or intercepted while in transit. SSH tunneling helps you to apply network protections to outdated programs that are not native.

The figure gives a simplified description of SSH tunneling. Safe connexions over an untrusted network are formed between the SSH client and the SSH server. This SSH link is secured, maintains secrecy and honesty and authenticates the correspondence of the parties.

Use of SSH SOCKS Tunneling

The SSH connexion is used by the program to connect to the server of the program. With tunneling allowed, the program contacts the local host port that the SSH client listens to. The SSH client then forwards the application to the server via its encrypted tunnel. The server then connects to the main application server-usually on the same computer or at the same data center as the SSH node.

Advantages of SSH SOCKS Tunneling

The benefits of SSH SOCKS tunneling are listed below:

  1. SSH tunnels are extensively used in several enterprise settings that use the mainframe structures as their program backends. In such contexts, the programs themselves can have very little native security protection.
  2. By using SSH tunneling, compatibility with SOX, HIPAA, PCI-DSS, and other requirements can be accomplished without the need to change programs.
  3. The SSH tunnel helps you to scrutinize the resources that are trailing after the firewall.
  4. It also discloses the local server to the internet.
  5. It also helps the IT professionals and network administrators to use it for backdoor opening within the internal networks by their systems.
  6. It facilitates you with some free alternatives. They are-
    • Serveo
    • Ngrok

Now your entire setup is installed. You can create the SSH tunnel for private browsing.

Configuration of Putty

Let's take a look at Putty configuration with the help of the following steps.

Step 1: First, you are required to launch the .exe file, and you get following screen.

Step 9: A window appears asking for the username and password. You will be signed in to your account until you enter the username, and password and the SSH tunnel will be enabled.

Creating public key authentication helps you to connect your network without inserting a password.

Browser Configuration to use a proxy server

The proxy settings enable an indirect agent to be placed between your web browser and the server call another device. A proxy is a software-based computer device that functions as something like a middle-man. On your device, you require the proxy setting to connect with the proxy server.

Since you've unlocked the SSH SOCKS tunnel, configuring your favorite browser to use it, is the last phase.

Here, we have explained the proxy server configuration for different browsers.

SSH SOCKS Configuration for Firefox browser

Some steps of SSH SOCKS configuration are given below. These steps are similarly used for Linux, MacOS, and Windows.

Step 1: First, you need to open the Firefox browser and then click on the ☰ (hamburger icon) at the upper-right hand corner. It helps you to expand the browser's menu, as shown in the below screen.

If you want to go back to the previous settings, then go to the Network settings, select the radio button of System proxy settings, and click on OK to save the settings.

There are also many extensions that can allow you to customize proxy settings for Firefox, such as FoxyProxy.

SSH SOCKS Configuration for Google Chrome browser

The default device proxy settings are used by Google Chrome. You can use a plugin like SwitchyOmega or launch a Chrome internet browser from the command prompt instead of modifying your operating system proxy settings.

You can also use the SSH tunnel with the help of the Command prompt in Google Chrome with the below-given commands.

If it doesn't exist, the profile will be automatically generated. This helps you to concurrently run several iterations of Chrome. "Launch google.com and search" "what is my IP" to verify the SSH tunnel is functioning perfectly. The IP address displayed in your browser should be your server's IP address.
