SSH tunneling is simple all you do is create an SSH connection to another machine. Configure the local computer to forward all communications through that tunnel to the other machine. The other machine connects to the internet and send data. Since the other computer is connected to the internet, we can tunnel through that machine and connect to the internet without a router. This assumes that you have a shell access on the computer that you are connecting into.

To create a tunnel you need to check that ssh service is running on the computer that you want to connect.
For Ubuntu or Debian based distribution:
sudo /etc/init.d/sshd start

For fedora or other RedHat based distribution:
/etc/init.d/ssh start

On the machine or the computer that you will use to browse the internet. Open a terminal window and type the following:
ssh -fND 2020 username@192.168.xxx.xxx

To start the proxy, SSH will ask you for the authenticity of your host, just type “yes” and enter your password. It will look as nothing has happened but SSH tunneling is already working.

Now setup your Firefox browser to use your proxy.

Click Edit - Preferences - Advanced and Network Tab

Under network click settings and Manual proxy configuration and enter “localhost” for SOCKS Host and enter “2020″ for the SOCKS Host port. leave everything else blank or at its default settings and click OK.

You should now be able to browse the web. Happy Browsing
