SSH Tunneling with puTTy and your browser

Posted by Shipcode at 6.2.12 Labels: , , , , , , , , ,
 

In this article we will discuss on how to tunnel using SSH / Secure Shell which can be used to hide your IP address or bypass firewalls at your school or office. SSH can also be used for forwarding TCP ports and x11 connections.

We will be using puTTy as our SSH client and it can be downloaded here. Follow this simple steps in order to cloak your IP address while you are surfing the net:

1. Run puTTy

2. Put the IP address of the SSH server that you want to use under Host name or IP Address Tab

3. Go to SSH tab >> Tunnels then put your desired port on the source port (In this example I will be using 9191 which we will soon put in the socks host port of the browser) then check Dynamic and click ADD.


4. Click Open then login with your username and password.


6. Configure your browser's network settings. Below are instructions for specific browsers that you have installed in your computer:

Mozilla Firefox: Tools > Options > Advanced > Settings > Manual proxy configuration.

Google Chrome: Options > Under the hood > Network > Change proxy settings > LAN settings > Use a proxy server > Advanced > HTTP.

Internet Explorer: Tools > Internet options > Connections > LAN settings > Use a proxy server > Advanced > HTTP.

Opera: Tools > Preferences > Advanced > Network.

7.  Insert this in your socks:

Socks Host 127.0.0.1 port 9191(your desired port)

8. Click OK after you are done configuring your network settings.


Alright now we're all set! To check if you have successfully tunneled your IP address, click this. If you see the IP address of the SSH server that you put on your host then you have successfully configured your browser with your SSH server. Congratulations!
