Who tried to unlock my PC

What is it about?

• It clicks the intruders photos who tried to access your system without your permission.
• On invalid login(wrong password), it clicks camera shots using webcam.
• It works only on Linux based systems.

Dependency:

• avconv

Setup

• Install the required dependencies.
• Go to /etc/pam.d/ location.
• Edit the 'common-auth' file.

cd /etc/pam.d/
sudo gedit common-auth

• Locate the line written below. It contains 'pam_unix.so' string.

    auth	[success=1 default=ignore]	pam_unix.so nullok_secure

• In this line, replace the 'success=1' with 'success=2' string.

    auth	[success=2 default=ignore]	pam_unix.so nullok_secure

• Now add a line below it:

    auth    optional                  pam_exec.so     (path to your script)

eg:

    auth    optional              pam_exec.so 		/home/nike/projects/wrongPasswordPic/wrongPasswordPicScript.sh

• Now on every invalid login, a web cam shot will be clicked. The shot will be stored at /var/tmp directory.

Feel free to suggest any change or contributing to it!!!
