How to access blocked websites using TOR browser

TOR stands for The Onion Router. According to me it is the best tool available for anonymity, privacy and unblocking on the internet. It keeps all your communication on the internet completely secure. It can be download free of cost.

All the data you are transmitting over the internet are in the form of data packets. Each and every data packets have two parts:

Data-

this is the actual data being transmitted over the internet.

Header-

This contains important information about the source and destination computers that is used to route the data through the internet.

         Now if your college administrator, company or even a government is running a data sniffer on the network, they can easily find out what websites and servers you are accessing. They can block you to access those websites.

          for your anonymity you can encrypt your data, but you can't simply hide the header of a data packet. So the administrator can simply apply a sniffing tool and read all the important information. This information can be about your online transactions or online data, which you never want to show to others.

           This is where onion router comes into picture to save you. In onion routing, the entire data is repeatedly encrypted with multiple layers (just the way an onion has multiple layers of skin) and these encryption layers are slowly peeled until the data reaches the destination. The working of TOR is shown below-

working Principle-

Step 1-

Assume that you want to connect to www.netpnb.com through an encrypted and secured channel. You have to connect to Tor network and open the TOR browser which comes in the vidalia bundle, you have already downloaded. Once TOR receives your request to connect to website, it will first connect to the directory server and download a list of all available onion routers that it can potentially connect to.

Step 2-

TOR will rendomly select three onion routers and create a secure encrypted connection between you and www.netpnb.com. The path created by the TOR is known as a TOR circuit.

Step 3-

once a TOR circuit is created, it will continue for the next 10 minutes, after which all new 

connections will give completely new TOR circuits.

Practicles-

Step 1-

After downloading the TOR Browser Bundle, you have to extract it. You can use it from a USB 

stick also. After extracting it will look like this...

Step 2-

Double click on the Start Tor browser. this will open the vidalia control panel as shown in figure

below...

Step 3-

Not more than 2 0r 3 seconds it will connect to the Tor network. as soon as the connection 

establishes, a new Mozilla Firefox window will automatically open looking like this...

Only this automatically open browser is configured to work with Tor Browser Bundle. all other 

application have to be configured manually.

If the administrator has also blocked the website of Tor and blocking you to download this

bundle then you have to just send an email to gettor@torproject.org. Make sure you type

help in the body of the email. They will reply with the instructions to download it.
