Use SSH Tunneling to surf net invisibly

Unable to surf net over work/college ? Want to surf net invisibly ? Well,we have a solution for that,SSH Tunneling.An SSH tunnel is an encrypted tunnel created through an SSH protocol connection. SSH tunnels may be used to tunnel unencrypted traffic over a network through an encrypted channel.In easy language,you can surf net without being monitored and even surf blocked sites too.SSH Is pretty awesome.
Without leaving your seat,you have a way to control a computer which ay be located anywhere on this planet.




And if you have access to a PC with an SSHd installed, you can channelize your traffic through that computer,which is particularly is useful in situations when -

1. The site is normally inaccessible from your current location (School/Work)
2. You do not want your connection monitored (You’re using a WiFi hotspot/You’re in a country that monitors/censors your internet usage)

In this tutorial,I will be using Firefox on Gentoo Linux , but it its applicable to all distributions of linux.
Step One: Setting Up the Tunnel
All common Linux distributions come with openssh packages. To check whether you have ssh installed already type the command "which ssh". Gentoo has opensh package preinstalled,so no tension :)
First we need to SSH to the server that we want to tunnel through, open up terminal and type the following command

ssh -ND @

Replace with a port number of your choice; This will be the LOCAL port whichFirefox will use to tunnel the traffic later on…Try to choose a high and random port number so as nobody scans or sneaks them in (system admin and firewalls)
Practical Example:

ssh -ND 2945 rishabh.cs07@sviet.ac.in

Now enter your password as usual, and it will hang after authentication, which is perfectly normal as it isn’t an interactive session- Now minimize the terminal and open Firefox.
Step Two: Configuring Firefox
In Firefox, Go to (Depending upon which version you are using)

preferences -> advanced -> Network -> connection settings
or
Tools –> options –> Advanced –> Network –> settings

A new window should appear,select the “Manual Proxy Configuration” option, you’ll need to type some information in the ‘SOCKS Host’ section.

Host: localhost 
Port: Port you used in the SSH command earlier.

Save your changes..Just to make sure it worked, check your IP with an online IP checker :)
