How to check your password's strength
Filed in archive Utilities by Rom Feria on November 03, 2007

To find out how easy passwords are cracked, try John the Ripper, an open source password cracker. This will allow you to detect if your users are using strong passwords or not. There is no point in having a secure server if one of your users is the weakest link, so to speak.
To install John the Ripper on Ubuntu, just run "sudo apt-get install john", and that should take care of it. Run it, "sudo john /etc/shadow" to start the process.
So, how many user passwords have you cracked?
