I've seen a lot of tutorials on how to crack a WPA/WPA2 Network using Reaver or Aircrack-Ng on Kali Linux. However, neither of these tools work for me.

With Reaver, after it switches to the correct channel (after a decent amount of time switching between channels), it just freezes and doesn't output anything, even with -vv as an option. With the Aircrack-Ng method, I never see a WPA handshake after sending a deauth package.

If this isn't the right place to ask about this, where should I ask for help on this? If this is the right place, what can I do about this?

Here is a picture from my iPhone that shows what pops up in my virtual console 1 after booting up. Everything above the part for entering the login shows up during boot, everything after that shows up after boot.

Picture of Virtual Console 1 After Booting

I don't know if this has anything to do with it, but it may. Regardless, does this pose any problem for my Kali Linux? I am running Kali Linux 2.0 on an ext4 partition.

If the installation process of Kali Linux makes a difference, it is contained in my post here: Warning while Booting into Ubuntu. This post of mine contains the warnings I get while booting into Ubuntu, which are similar to that of booting into Kali Linux.

So I guess I have two questions:

  1. Where can I get help using tools like Reaver or Aircrack-ng?
  2. Are the warnings in the image anything I need to worry about?


Here is information requested about the errors:

For the ext4 one, my installation completed successfully. It ended saying that I could reboot into Kali now. However, if you look in the link I provided, it shows about my installation procedure, and there were some parts that I believe were not that significant that I could not see any options for, as part of the installer was cut off on my display, but I'm not sure if that was the problem.

My Wifi connection works fine, as I am posting from Kali Linux. However, I can just try sudo apt-get <app> if I must. I don't know what the name is for the iwlwifi firmware.

I just tried running the command regarding the openvas-scanner, and then with the -l option, which it said to show extra information, and this is the output:

sudo systemctl status openvas-scanner.service -l
● openvas-scanner.service - Open Vulnerability Assessment System Scanner Daemon

If it makes a difference, my Kali Linux is on a logical ext4 partition. I also installed Kali grub the second time going through, which is what is run now instead of my Ubuntu grub.

This is the output from lsusb:

There are some pretty serious issues highlighted in that screenshot.

  1. mmc0: Unknown controller - this one is probably nothing to worry about
  2. fsck: error 2 (No such file or directory) ... fsck.ext4 - you're missing at least some of the system utilities for managing ext4 filesystems. Did the installation complete successfully?
  3. iwlwifi ... firmware: failed to load iwlwifi-7260-12.uc - your WiFi firmware isn't installed so the card will neither be initialised nor available for use. You need to install the missing firmware from the repository.
  4. failed to start Open Vulnerability Assessment System Scanner Daemon. See 'systemctl status openvas-scanner.service' for details - have you run the command it tells you to run, to review the problem?

You really need to address these issues before trying to move on further.

When you don't know the name of a package there is a very useful command called apt-cache that can help you find it. From there it can be installed in the usual manner.

apt-cache search iwlwifi
firmware-iwlwifi - Binary firmware for Intel Wireless cards

apt-get install firmware-iwlwifi

Personally, for my Debian systems I prefer the interactive mode of aptitude. (Run the program, then / is the search key, so /iwlwifi, and then + to mark for install and g to go and apply the changes.)

It seems that Kali uses an older version of the iwlwifi package that doesn't support your 7260 WiFi card. If you follow through the answer from smoortema for No wireless for Intel Corporation 7260 version 63 over on Ask Ubuntu you should find it works for you too.

  • Anything about the last part (The CPU pipe A FIFO underrun)? I added information about the others to my question.

  • It says firmware-iwlwifi is the newest version. I tried apt-get install firmware-iwlwifi. No good. Then I tried apt-get --reinstall install firmware-iwlwifi. Boot errors still persist. I also tried apt-get --reinstall install openvas-scanner (which is probably causing the reaver issues). The errors still didn't go away during boot. I don't exactly know what to do. i am also getting errors when booting up into my other OS, Ubuntu. Would the best option be to erase both OS's and start fresh? I don't have much, it won't be too difficult a change. However, if I can fix it, I would like to try.

  • @Rohan are you really running an IWL wifi card? Output of lsusb or lspci will have a line for the WiFi device. please can you add that info to your question. Better, also check that the card has the right driver :) Oct 20, 2015 at 18:04
  • I'm sorry but I am really not that tech savvy. How do I check the card has the right driver? I would really appreciate it if you could give me instructions/commands for all of these things. I'm still learning computers :) I will check what WiFi device I have.

  • @Rohan run the two commands I gave you in the above comment. Paste (please don't screen shot if you can avoid it) the output into your question Oct 20, 2015 at 21:21
