Hello everybody and welcome to this tutorial. Today, I will show you how you can install aircrack and Reaver.

The aircrack setup is pretty simple. Just type in yum install aircrack-ng, and it’s going to pick up the right version by default. Go ahead and press Enter. In Fedora it runs through checks every time you call yum, you can pass the -c argument in order for the system not to do that. It says package aircrack-ng is already installed and is the latest version. You might be prompted for a question along the way. If you wish to skip that type in -y, that’s it. With this command that I am selecting you won’t be prompted for any questions, and you will have aircrack-ng installed on your system without any problems.

However, Reaver is quite a different story. Reaver cannot be found in Fedora’s repositories, and therefore it has to be downloaded from the internet. There are many places to download it, I have chosen to download it from Google code. Google code is one of the safest sources on the internet. Let’s go ahead and open up my favorite browser, which is Firefox, you can open whatever you wish. Type in “reaver google code.” Now we are on the Google code website where we have reaver-wps, you have a description here, and you have a pro version here. The difference between the pro version and the free one that we will be using is this graphical user interface. I mean, let’s face it, if you’re a pen-tester, or a white hat hacker, you’re not going to be using that many GUIs. Optimized PIN sequencing, this means that it’s going to try pins in a certain order, which is more likely to succeed than the default one, according to some but not necessarily true, and integrated WEP cracking. As I said, you don’t really need WEP support. You’re not going to be able to find this protocol these days pretty much anywhere. If you do, as I said before, those people don’t deserve to use WiFi. It’s basically and open WiFi network, regardless of how complex your password is. Make sure you are not one of the people using the WEP protocol. It’s a good idea to switch to WPA or WPA2.

Anyway, I’m going to go ahead and click on downloads in the upper left corner, and there are different versions here that can be downloaded. There are no fundamental differences in the way that Reaver works in between these versions, but there are bug fixes, definitely, and that is very nice. Reaver is maintained, there’s support for it, and so on. So, go ahead and click on Reaver 1.4.tar.gz, and it says reaver.tar.gz here, file description, etc. This is a checksum, you can use this in order to verify that your file is intact, but I’m not going to do that now. I’m going to go ahead and download it. Once it is downloaded, you can go ahead and open up the folder in which it actually exists. Go ahead and double click on this file, you can extract it through the GUI method, it’s far simpler. You can also extract it through the terminal, but I’m going to go ahead and use the GUI on this occasion. This is one of the advantages of Linux over Windows. By default, it will be able to unpack pretty much anything zip, tar, winrar, whatever, it’s going to be able to unpack it without any problems, which is fantastic! No extra installation is needed, this is all installed by default. Let’s go ahead and click on extract. Where would I like to extract the file to? Let’s say to desktop because I’m going delete it anyway, as I already have it installed. So, just go ahead and press OK, and give me desktop. Let’s go back to our terminal, navigate over to desktop, and I imagine I have a lot of things there. OK, so, cd /home/Chronic/Desktop, Enter, ls, and do I have it here? Yep, there we go. So, clear, let me just show you that I do in fact have it, ll. It’s much neater if I do it like this, and there we go, reaver-1.4. Let’s navigate over to that folder, reaver-1.4, clear the screen, list the contents of the directory. Go to docs first and let’s see what is in there.

You might think that I am some sort of an expert, and that I just do these things off of the top of my head, but no. People create readme files for a reason. They are there to be read because the developer has left specific instructions on how to do something within the software. So, let’s go ahead and cat it. Excellent! The following are Reaver source files. It has the description of what is located in each one of these files. You have 802.11.c functions for reading, sending, and parsing 802.11 management frames. 802.11 is a standard, as I said before, but look at this. The developer has actually left the entire installation process here. You have every single command that you need to run, explained in detail what it does, and how you can type it in and execute it. This is wonderful! That’s why when you download a new piece of software, check out the readme file. People do tend to leave instructions there on how to do essential tasks within the software. They’ve most likely encountered the same problems that you might have encountered so you can even see possible solutions. Reaver is only supported on Linux platforms. It requires libpcap, this libsqlite3, and one more, I can’t really pronounce this, and it can be built and installed by running the following command. So, execute the configuration script, and that’s it. It even tells you how to uninstall it.

Anyway, ls, of course you cannot run the configuration file from here. We need to reverse course, and go to source from, yep, src. Let’s see what is in there, there we go. We have configure, and you can see by default here it’s executable. If I give you a longer listing, configure, there you go. It has an x permission here, here, and here. So the user has it, and the group has it as well. Anyway, type in ./configure. So, now it’s checking for stuff, it has its dependencies, without which it cannot function. Type in make, there we go, it’s running through. I want to reiterate that I didn’t do any of this from memory. I just went on the internet, I found the safest place to download the code from, and I’m compiling it here as the developer of the code instructed me to do it. The instructions aren’t complicated, just three commands, and the final command is make install. It’s going to give me several errors here, well not errors but warnings, because I already have it installed. Here it says rm, I need to clear this out, and then I will be able to install Reaver. I will now abort the installation because Reaver is already installed on my machine. If you have any problems feel free to post it in the discussion section.

Lastly, let’s check to see if Reaver is functioning properly. So, type in reaver –help, excellent! It is installed, it is functional, it is responsive to our commands, and here is the syntax for reaver. This is the basic syntax. Of course, you can pass all of these arguments to it, and there are quite a lot of them. Basically, you can say -i for the network interface, and -b for BSSID, or for the MAC address, and of course we even have reaver -vv for double verbose output, which is fantastic! I’ll go ahead and clear the screen. That is how you install aircrack and Reaver on Linux. We will cover the Windows procedure in the next tutorial. Until then, I bid you farewell!
