Access Blocked sites using SSH Tunneling

In many school and college networks, there are many websites blocked having facebook as a common one....
In this post, I m telling how you can access that blocked sites using PuTTY as an SSH client.

PuTTY is an SSH client. You can use it to access a remote CLI, or you can use it to set up a tunnel — and that’s what we’re going to do now...

First, download PuTTY (putty.exe). It’s a free, standalone program that doesn’t require installation — so just make a shortcut on your desktop.

Next, you need a Linux or Unix server to be as your host server, throught which you will access net. You can use a free one (which might involve you jumping through a few hoops to get an account activated), or you can rent a cheap Linux Server for some rupees. Either way, you need an SSH account on a remote server, and the IP address and port that you need to connect to.

Now open putty and enter the server name or ip address and the port on which the server will listen on the specified fields. Make sure SSH is selected on the connection type. It should look something like this:


In the left-hand panel, navigate through Connection > SSH > Tunnels (see below). Enter any port(more than 1003, here 8080 is used) in the Source Port box and select the Dynamic radio button. Click Add and “D8080 (or your entered port)″ will appear in the Forwarded Ports list.

Now move back to session in the navigation panel, type any name in the sessions box and click save to save your setting. Now, click Open at the bottom of the PuTTY and a new window will pop up asking for your login name; type it in and press Enter. Type your password in and press Enter.


Yeeeeeaaaaaaaaaaaahhhhhhhh!!!!!! Now you have created an SSH Tunnel....
