How to unblock Tor if it is blocked ?

                                               Tor blocked 
In the previous post we have seen about Tor and how we can stay anonymous on the Internet. But in case it is blocked by your network administrator then how to unblock it ? Don't worry here is the solution for that problem.

Reason to block Tor

*. Due to the rising popularity of the Tor application, lot of colleges, companies and organization started to block even Tor.

*. They mostly block access to all the publicly known relay servers. If network administrator blocked access to these relay servers then Tor would stopped working and you would not be able to connect to any blocked website on the Internet.

*. You can see complete list of Tor relay servers on the Vidalia Control Panel by clicking on View the Network button.

How to unblock Tor

If Tor relay servers blocked, then there are Bridge Relays come to the rescue. Bridge Relays are Tor Relay servers (Onion routers) that are normally not published in the public network list. They are hidden servers which are unknown to anyone of us and even the network administrator and so that they would not necessarily blocked.

bridge relay servers

To find Tor bridge Relay servers or Tor Bridges there are two ways as follows:

*. Visit to the webpage and click on get bridges you will able to get information about some new Tor bridges.

*. If the above webpage is blocked then you may request for Tor bridges by email. For this send an email to with the line get bridges in the body of email and make sure to send this email by your Gmail or Yahoo account because any other email account will not be accepted.

 Within few minutes for should receive a reply containing some bridges that you can use. But sometimes this method doesn't work, you can use other devices like mobiles phone to access the webpage and get the bridges if Tor webpage is blocked in your organization.

Once you have received Tor Bridges information you need to configure the Tor application to use these new bridges.

To do this open Vidalia Control Panel > Settings > Network and select the option My ISP Blocks connection to the Tor network. Now you will be presented by a box below, where you can add IP addresses of the new Tor bridges. It is a recommendation for you that add as many bridge as you can to make it harder for your college, company or organization to block you.

Some network administrators also block the various ports that Tor uses for communication.

In such case, it is possible to force Tor to use Port 80 and Port 443 for all its communication. Port 80 and 443 are normally not blocked because these ports are the default ports that are needed for Internet communication. To configure this option go to Vidalia Control Panel > Settings > Network and select the option My Firewall only lets me connect to certain Ports.
Mostly this will resolve the issue of blocking.

Protect your privacy with TOR

Everyone in the world wants to browse the Internet anonymously. You have different ways to stay anonymous on the web like proxy servers, VPN servers, etc. but sometimes most of the proxy servers are blocked in public place where you want to access the Internet.
For this you have one option other that proxy sites i.e TOR.

What is TOR ?

TOR which stands for The Onion Router is a free software that is the best software for anonymity, privacy and unblocking websites.

TOR has thousands of servers in different parts of the world through which user's data routed and tunneled in encrypted format with the intention of keeping it completely anonymous.

It not only protect your privacy by keeping you anonymous, it keeps your communication on the Internet completely secure. It can be downloaded free of cost from

How TOR works ?

When you want to connect to the secure and anonymous network you first need to install TOR on your computer. When you have configured your browser to connect to the Internet through TOR and once TOR receives your request to connect to the domain name (For ex. that you want to connect, it will first connect to the TOR directory server and download a list of available TOR relay nodes (i.e. onion routers) that it potentially connect to.

TOR will now create a secure and encrypted network between you and the domain you want to connect to and route the connection by randomly selecting onion routers one after the other.

TOR always connect to three randomly selected onion routers in any part of the world before connecting the user to the destination system, hence it ensures the anonymity of the user. TOR always an advantage over the poxy servers by ensuring that it always connect to three different onion routers and on the other hand proxy routed through only a single system.

Once TOR circuit has been created, it will continue to be used for all the connection for 10 minutes or so, after which all new connections will be given completely new TOR circuits. It is also possible to change TOR's circuit sooner than 10 minutes if needed and in this case your identity also changes on the Internet.

How to use TOR ?

*. Download TOR Browser Bundle from here.

*. After downloading it can be extract anywhere on your computer or you can use it by extracting it on your USB pen drive. To launch TOR double click on start TOR Browser icon.

TOR browser files

*. After you launch TOR you will be presented the Vidalia control panel and TOR will connect to its directory server and download a list of TOR onion routers. and then try to establish a secure and encrypted connection. As soon as secure Tor connection established the Mozilla Firefox browser window will automatically open. 

vidalia control panel

*. The Firefox window that opens will also say Congratulations. Your Browser is configured to use Tor.

tor browser started

*. You can check your connection for anonymity by visiting

*. Note that only the Mozilla Firefox Browser which automatically opens will work with TOR and all the other installed applications and browsers will not automatically connect to TOR.

If your college or organization block access to the Tor project website then you can download it by email also. To download it from email send an email to and make sure you typed help in body of email and they will reply you with the instructions to download Tor and if you are using Windows then you have to reply them with keyword windows in the body of email.

Enjoy safe, anonymous and secure browsing on the Internet.

Working of Internet

All of us using internet everyday and we can say that now we are unable to live using internet today. But can we imagine how it works ? Don't worry we will see now how the internet actually works.

Working of the Internet

*. The data you access on your PC is stored on the main computer that we call as Server and the data sent from the server to the client. The client is a computer from which request sent to the server for accessing data on it. Client can be laptop, PC or smartphone. These both are the end points that make a chain of the internet.

*. Every client/server use a network card to access the internet and a unique address called the IP address.

*. All the data sent to the internet is in the form of packets. When you click on any image on the webpage, the data that makes up that image is divided into smaller parts i.e. packets and then these packets sent over the internet and when every packet reach to its destination then they combine to form an image that you clicked.

*. Remembering IP address is a very worse thing to do, isn't it ? But to solve this problem domain name system included. It is basically a contact book that keep track of the IP addresses and their associated names. DNS is a domain name server that hosts a database of domain names that can be referred to.

For example: can be written on the address bar as

What happen when you type a website address ?

*. If you type '' in the address bar.

*. Your computer translates that data into the request that is sent via your local Internet Service Provider (ISP), which will then connect to the DNS server for knowing the IP address of ''

*. The local ISP will have regional ISP above it. The regional ISP will in turn contact a Network Service Provider (NSP) that will contact a Network Access Point (NAP). All these are routers. Once the DNS tells the system the IP address that you are looking for, all these routers will try to find that IP address.

*. Once the addresses are resolved and the server located, your request is finally submitted and the server responds with data. The data is sent in the form of packets.

*. So then finally the packets arrive to the client. They are already with the information needed and you browser then automatically collects and combines the data and interpret it. These all things happens in a matter of millisecond.
