Category: Wi-Fi (Wireless Fidelity)


This question has not yet appeared in my inbox, although since I have already written an explanation on the meaning of the term “Sniffer” it makes sense to write one about a tool commonly used in conjunction with a “Sniffer”. So here is an explanation on what a “Scanner” is and what it may be used for. Note I am referring to a “Network Scanner” not an optical scanner.

A “Scanner” is a shortened term for “Network Scanner”. The “Network Scanner” is a software program that can be used to passively scan for network broadcasting devices, such as a wireless access point (AP) that could potentially be exploited in order to gain unauthorized access into a system belonging to the network connected to this wireless access point, or perhaps authorized access assuming you have permission from the owner of the network or computer to perform a security audit.

 

By using the term “Passive Scan” I am referring to a scan in what is commonly known to security enthusiasts as a scan in “Monitor Mode”. This means that the wireless device will only capture data packets and broadcast beacons without sending and data packets. Thus making you much less likely to be discovered by the owner of the device or devices that you are collecting data packets from. I would also like to note that in most circumstances collecting wireless packets should be no more illegal than say peering into your neighbour’s lounge room through the front door that he left open. It is in principle no different. Just be sure that if you do choose to pursue the data packets of your surrounding access points that the owner of them is not a security freak or a person with a great lawyer, as this could result in them turning the tables on you and getting you in trouble.

 

Due to the haze between the terms “Sniffer” and “Scanner” personal opinions on each may vary. My preference in network sniffers would be Wireshark and my preference in “Scanner” would be Airodump-ng.

I hope that this has helped you understand the meaning of the term “Scanner” when referring to network security. Have fun testing your network from the outside, perhaps it is not as secure as you may have once thought.

This tutorial is designed to teach all computer users, of which are new to their Linux distribution. Read below to find out what the most commonly compatible wireless devices are and how you are to install them on your Linux-based computer with the aid of open-source driver projects.

The initial step you must take, just as you must in any other hardware installation on any type of computer system, is of course to physically connect the wireless device to your computer system, either via a PCI slot,assuming you are using a desktop or tower type computer system or a free add-on slot, assuming you are using a laptop type computer system. Also after connecting the hardware be sure to check that the system voltage has not dropped overall using your voltmeter, as strenuous load on the power supply may not be all that bad, overloading the power supply will cause hassle when trying to run your computer, most commonly random reboots and hardware failure will result under these circumstances.

 

The next step you must take is to determine the make and model of your wireless device, which can be done by reading the box that contained your wireless device at the time of purchase or you may consult a computer store or a computer savvy friend to determine the make and model of your wireless device. As it is not installed yet, thus checking for the make and model in the device list is futile.

 

Please note that this tutorial is referring to the “Chipset” in use on the wireless device, so not only the make and model of the card are being referred to here, but also more specifically the “Chipset”on board that device.

 

Below is a table of the commonly compatible wireless devices and where you are to find online hardware lists and driver installation packages for them. You may also note that below I have only listed the makes of the commonly compatible wireless devices, as listing all compatible models would take vast amounts of time, although don’t fret as the driver installation packages available online are usually compatible across most models of the same make:

Zydas (USB) http://zydas.rapla.net http://zd1211.ath.cx
Intel I have not found a hardware list for this specific make yet. http://ipw2200.sourceforge.net/downloads.php

http://prism54.org/newdrivers.html (SoftMAC)
http://prism54.org/fullmac.html (FullMAC)

 

Once you have determined the make, model and chipset aboard your wireless device, you must then visit the “Hardware List (Compatibility List) link beside the make of your wireless device, once you have navigated to the webpage, you must then search the page for your specific model, which can be done by using the “Filter”/”Find” tool, which is activated by using the key combination highlighted below:

Ctrl + F            Press and hold “Ctrl” and then tap “F” now release both keys.

 

Once you have used the above key combination correctly you will be presented with a narrow, empty text box, of which you must type the model of your card into (or at least the first few characters) and then hit the “Enter”/”Return” key to search the page for the entered text.

 

If the box suddenly highlights itself “Red” then your model is most likely not on the page, if this happened check that you entered the model name correctly and try again, if the box remains “Red” then try removing one character from the end of the text at a time until the box is no longer “Red”. If your box remains the default colour then you will notice that the text you entered into the box will now be highlighted (more than likely in a pale yellow) and if the highlighted text on the webpage matches the model of your wireless device then you can be sure that your wireless device should be compatible with Linux, thus allowing your wireless device to function natively under the Linux platform.

 

Now that you have determined that your wireless device is compatible with Linux, you must then return to the top of this page and click the link beside the make of your wireless device in the “Driver Package” column. Once you have clicked the link in the column that is most appropriate to you, you must then select the driver package that is most suited to your system. In most cases, you will select the driver marked with your Linux Kernel version number of the type of processor and operating system you are running (i.e. 32-bit, 64-bit, x86, etc).

 

Once you have downloaded the driver package (which will be a file format specific to your distribution i.e. Debian = .deb or .tar or .tar.gz, etc) most appropriate to your system and wireless device, you must then install it. Depending on your distribution and wireless device this procedure will vary and I strongly recommend that you consult a computer savvy friend, a computer expert or good old http://www.google.com for any information that you may need.

 

Once you have installed the driver package, you must then reboot your system and if you have an external wireless device switch (common on factory installed wireless devices) then switch it on. Now if you have configured it correctly by using my instructions above, then you may sit back and watch the glory reveal itself in the form of blinking data transfer lights and the swift readiness to occupy our air with its wealth of bits and bytes and make all of the fidelity of the wireless variety come to life invisibly. Fascinating isn’t it? If you do not experience such pleasure and your wireless device is in fact inactive or only partially active then I would personally recommend that you continue to search this website of mine for the answer that suits you, otherwise you may consult a computer expert.

Congratulations! You have just installed your wireless device on your Linux-based computer system. Enjoy your newfound Linux hardware configuration knowledge.

This guide is written keeping in mind the Xbox players out there who find that paying copious amount of money on top of buying your console just to connect wirelessly to your network. Microsoft does like their price overkills though, such is displayed in the price of their console of which seems amplified by the fact that they charge you extra just to play online! Read below to find out how you can get online wirelessly on your Xbox 360 without letting Microsoft con you out of your hard earned money.

Before I commence my guide I would like to suggest a guide of mine that shows you how to play on Xbox live without paying a cent. This will surely prove to Microsoft that they can only charge us once for the use of their console. The link to the guide is below:

Also, you may be interested in a guide on how to backup your Xbox 360 games using Windows. If you would like to learn how to do so then visit the link below:

https://chafflube.wordpress.com/2010/10/10/how-to-back-up-an-xbox-360-game-using-windows/

 

The first thing you will need to do is gather the items from the list below:

    • A Windows laptop with Wi-Fi capabilities
    • An Ethernet cable
    • An internet connection
    • A router (or modem router, or another LAN connection point)
    • An Xbox 360

Once you have collected all of the ingredients from the list above you can then proceed to the next step. The next step is to go to your Wi-Fi capable laptop running windows XP or later and head to the control panel (Start – Control Panel).

 

When the control panel opens you need to go to “Network Connections” (in Windows XP) or go to “Network & Sharing Centre” (in Windows Vista). Highlight both the “Local Area Connection” and the “Wireless Connection” simultaneously and then right-click one of the highlighted connections and select “Bridge Connections”. Doing this will create a link between your wireless and wired connections, allowing your Xbox 360 to connect through your PC via an Ethernet cable and use your laptop as a Wi-Fi adapter.

 

Once you have bridged your network connections on your computer, you then need to connect one end of a standard Ethernet cable to the Ethernet port on your Xbox 360 and then connect the other end of the Ethernet cable to the Ethernet port of your laptop.

 

Once you have done this you need to power off your Xbox 360 and the LAN device (router or hub/switch) for 20 seconds. Once 20 seconds have passed you need to turn on the Xbox 360 and the LAN device (router or hub/switch) being sure to keep your laptop powered on with an active wireless connection to the LAN.

 

You now have a laptop posing as an Xbox 360 Wi-Fi adapter, not only are you now able to play online without the need of lengthy cables commandeering your house’s floor as well as use the laptop for any daily purposes that you normally would, as this type of connection to your Xbox 360 will in no way impact the ability to use your laptop offline and online. This is especially good if you have a few laptops in your house and you have a few of your mates over and decide you all would like to play online sharing an internet connection, although other members of the household do not enjoy tripping over unsightly Ethernet cable laying throughout the house.

 

Now that you have your new free Wi-Fi connection for your Xbox 360, why not find out how to get a premium Xbox live account for free? To find out how visit the link to my guide below:

For all of you out there who have found an external Wi-Fi (Wireless Fidelity) Antenna hard to come buy or simply have not had the motivation or money to go out there and buy one. Read below to find out how easy it is to make your own fully functional Wi-Fi antennas.

You will need a couple things before you can begin building your antenna. The items you will need are as follows:

  • Wire or solder (as thick as possible without being too difficult to bend)
  • 1 thumb tack
  • A clean open workspace, a desk is ideal.

Now that you have gathered the materials you can begin the assembly process.

 

Firstly you will need to get our thumb tack and begin to wrap the wire/solder around the point of the thumb tack. Doing this will turn the wire or solder in to a spring-like shape with the thumb tack sticking out of the end, ready to connect directly into the external Wi-Fi antenna port. Be sure that the end of the coiled wire is firmly wrapped around the metal surface of the thumb tack to ensure full contact as to prevent dropouts and signal loss.

 

Once you have coiled your wire and it has been securely attached to the thumb tack via tight loops then you may push the thumb tack into the centre of the antenna output. Also, you can add to your connection strength by making sure that any stray wires are wrapped around the metallic externals of the external antenna plug.

 

Always be sure that your antenna is as high as possible and preferably attached to another small metallic object, such as a metallic salad bowl or a wire frame or something or something similar. Also, it will help a lot with signal strength if you place a straw or some kind of electricity resistant tubing over the coil.

 

Now make sure your rig is completely connected and that no stray wires have protruded into your PC case, as that could create possibility of system damage or failure.

Now you are finished, you have your very own wireless antenna that you can use for whichever purpose you find most applicable. Enjoy your newfound antenna building knowledge.
