WPA_Supplicant config for WPA encryption Backtrack 5

Why use WPA_Supplicant Daemon?

Wpa_supplicant config

So after finding an old Backtrack 5 R3 persistent USB drive I had created years ago, I booted it up to browse the content I had on it. Last time I used it, I was connected to a WEP encrypted network, but as we all know those offer weak protection and are slightly outdated for today. The tools and techniques to break WEP encryption have been around for a while and therefore WEP is rarely used these days. That being said, WPA encryption isn’t flawless, but a better alternative. I’m not going to discuss how to crack those here. Anyway, I figured I would share with you how to connect to a WPA encrypted network in Linux using the terminal and WPA_Supplicant daemon.

If you’re still using Backtrack 5 R3, I recommend upgrading to Kali Linux by creating a persistent USB.

Normally, we use iwconfig to configure wireless networks. However, iwconfig does not support WPA/WPA2 encryption. We have to use the “WPA_Supplicant Daemon” to connect to a WPA encrypted network.

Wpa_supplicant comes pre-installed in most Linux distros (including Backtrack 5 R3, Kali Linux and Ubuntu). Since Backtrack 5 R3 is outdated, it is configured to make connecting to WEP encrypted networks easily,

Arduino Kits – Which one should you buy?

There are so many Arduino kits in the market which you can purchase. If you are new to Arduino, the choices can be overwhelming. They have kits on Amazon and kits on Ebay, but where do you get started?

I recently read a great article over at pretzellogix.net before making any recommendations. There are 4 kits the site compares:


  • The Official Arduino Starter Kit
  • The Sunfounder Super Kit
  • Sparkfun Inventors Kit
  • The ARDX Starter Kit

TechSide - Robocopy Command Line

Robocopy Command Line Tutorial

For: Windows

In an earlier blog entry, I showed you how to use Xcopy. This time I will show you an even more powerful Command(CMD) line utility called Robocopy, which is short for “Robust File Copy”. The Robocopy command line utility has even more advanced options (or switches), and was apparently released to replace Xcopy in newer Windows versions. I’m running Windows 10 and I have Xcopy commmand line and Robocopy commmand line, pre-installed on both of my Windows machines.

…[Robocopy Command Line] strengths include the ability to copy all NTFS file attributes and to mirror the contents of an entire folder hierarchy across local volumes or over a network.

Robocopy Command Line Syntax

robocopy Source Destination [File[ ...]] [Options]

To see the full list of options, type robocopy /? in the command prompt. The syntax of robocopy command line is different from other copy commands in that it accepts folder names as its source and destination — meaning you cannot use *.* or ?. However, certain files can be selected. If we want to copy a file named myinfo.txt from C:\draft” to “C:\published” then we can run the following command:

robocopy c:\draft c:\published myinfo.txt

Love the Start button? Now added to RT devices.

I have had the Microsoft Surface RT since it first released, back in 2012, as it was given to me as a Christmas present.  I was very disappointed when I found out that it utilizes an ARM processor and cannot run all the usual Windows applications.  Only apps that will work on the RT are from the Windows Store (unless it’s jailbroken, but I didn’t want to do that — not worth it for a few extra applications).  Even still, I have used the Surface more then I initially expected — It comes pre-installed with the basic MS Office applications (Excel, Word, OneNote, etc.) right out of the box — so it was good for note-taking.  If I needed to use any actual Windows Software to perform a task (Photoshop, etc.), I can just Remote desktop into my PC using the RDP app for the Surface RT.  I used my Surface more in college than my laptop because of the size–it was easier to carry around.

One major issue I had with the Surface RT was the Windows 8 start button behavior.  Push the Start button and you get the following screen:

Microsoft’s new “Start Screen” for Windows 8

I hated clicking the Start button and getting the above screen.  “What happened to the original Start button Windows is so well known for?”  This is one of the reasons I never upgraded any Windows 7 desktop/laptop to Windows 8.

XCOPY usage - quickly copy files in Windows

“XCOPY” stands for Extended Copy, and was created to add more functions then the standard copy command. If you are using Windows, it should be installed already.

XCOPY is a command used on PC DOS, MS-DOS, OS/2, Microsoft Windows, and related operating systems for copying multiple files or entire directory trees from one directory to another and for copying files across a network. — Wikipedia

Xcopy copies multiple files and folders and can create the same structure to the copied location. (Something the copy command cannot do.)


xcopy Source [Destination] [/w] [/p] [/c] [/v] [/q] [/f] [/l] [/g] [/d[:mm-dd-yyyy]] [/u] [/i] [/s [/e]] [/t] [/k] [/r] [/h] [{/a|/m}] [/n] [/o] [/x] [/exclude:file1[+[file2]][+[file3]] [{/y|/-y}] [/z]

DashCamPro – As Seen on TV. Worth it?

I actually wasn’t interested at all in purchasing a car dash cam. I was in the market for a Go-Pro to take some action shots. I ended up seeing the commercial for the “DashCamPro” and I figured it was pretty neat, especially for the price. But I have had experience with similar “As Seen on TV” products, and they do not generally work as advertised and/or die quick because of poor/cheap-quality materials when manufacturing. Generally the commercials market these items and make them look better then they actually are. The video quality was amazing in the commercial, but I’m sure I missed the small font, “screen images simulated” somewhere during the commercial. It seemed too good to be true:

This is the ad from their website. $39.99!

Fix a broken remote control - Tutorial

Replace remote control infrared LED

I purchased a Dynex 32″ TV for my apartment during college. It was a really good TV, however the remote control wasn’t that responsive. The remote got worse over time, and practically became useless within a year. So instead of purchasing a new remote, I decided to open my current one up to see what was wrong with it. I figured it was either the IR receiver on the TV or the IR Transmitter on the remote control. You can also use this tutorial if your remote is very weak. If you have to be very close to the TV to change channels even with new batteries, means infrared LED is weak.

Note: This tutorials assumes that you have soldering experience.   Please make sure you take caution when working with a soldering iron.

Add apps to right-click menu - Windows

Tutorial should apply to Windows Vista/7/10

Please be careful when editing the registry.  Create a backup in case you accidentally delete/modify the wrong value — it can damage your Windows OS.

When you right-click an file, such as a .txt file, Windows will give you a few options you can perform with the file – this is called the Context Menu.  I currently have Notepad++ as my default text file editor so all my text files open with Notepad++.  However, sometimes I prefer to open them with my new, favorite editor “Sublime Text.” It is an awesome text editor, especially for coding.  Currently, right-clicking a .txt file does not give me the option to open it with Sublime Text.  (of course I could always make Sublime Text my default text editor, however this tutorial is about showing you how to add any application to the right-click context menu).

Currently if I right-click my .txt file I get the following menu:
