I read that I need to download cackey from but the download isn't there any more. How can I get my CAC reader working now? Is there a sudo apt-get command for it? Does someone have a copy of the file? Is it located else where because I can't find it.

If you cannot access DISA's website, (Because it requires CAC access)

You can Download the 32bit Deb file here.

you are the man – dustin Apr 26 '13 at 16:26
I'll take that to mean it worked. :) Also, for what it's worth, 12.04 & 12.10 gave me issues accessing Enterprise E-mail OWA, but 13.04 works like a charm. I think it's an issue with the way the 12's select the cert. – Argusvision Apr 26 '13 at 17:55
@Arguvision what did you do to access the EE? I go the site, hit ok, enter my pin, and then get an error screen. I am using 13.04 as well. – dustin May 20 '13 at 19:33
I haven't done anything special. From a fresh install, I followed the steps I laid out at… . Take a look at it and see if you're missing a step. Also, once you receive an error message you need to close firefox before you try again, or you'll just keep getting an error. If it will allow you to chose a cert, make sure you select the "e-mail" cert or it will fail. – Argusvision May 21 '13 at 1:07

This is what I have done and I successfully accessed AKO, enterprise email, and even the disa site for cackey.

  1. sudo apt-get update
  2. sudo apt-get dist-upgrade
  3. Open a terminal and type the following: sudo apt-get install libpcsclite-dev pcscd pcsc-tools libccid build-essential autoconf
  4. Restart your computer
  5. Open a terminal and type: pcsc_scan [check to make sure you have an output and it does not get stuck on Scanning present readers....]
  6. Go to Ubuntu Software Center and search for coolkey and install
  7. Download the DoD Configuration Extension for Firefox @ (Let it install the plugin and restart; don't worry about all of the errors just click through them and restart your browser).
  8. Go to Edit > Preferences > Advanced > Encryption > Security (You should see your CAC id visible)
  9. Go to AKO ect...

I get an error when I go to login to AKO. SSL peer can't verify your certificate. – dustin Mar 30 '13 at 21:08
@Cameron - FYI, Coolkey only works with older cards. For the newer (144k) cards you need cackey. – Argusvision Apr 26 '13 at 18:00
And, you don't need step 7 – Argusvision Apr 26 '13 at 18:02

For what I read, what you need is some authorization to be able to download. See How can I get access to (CAC users)?

It says you need your CAC to register. That puts me in a conundrum since my system is Linux only. – dustin Mar 19 '13 at 1:06

If you don't want to trust the download links in @Argsvision's answer, or just need to use a CAC only briefly. You can use the USAF's Lightweight Portable Security (LPS) ISO to access and other CAC-only sites. Get it from After using LPS to download the CAC files from you can then follow the steps in @Argsvision's answer.

You can thus use the LPS ISO to "bootstrap" a computer without any other computer that can use a CAC or trusting anyone except the site.
