Thanks in advance for taking the time to answer my question.

>I am in an Applied Cyber Security class.

>I am using VMWare to run Mint Linus 64 bit.

>I am using John the Ripper to run a password edit on the file. I can run John in all its modes as long as i manually add the users into my console. ( ie- >sudo adduser SpongeBob . The system then adds the user then prompts for room number, phone,and so on.)

>My question is how can i get John to read and crack passwords with the text files that have been provided (as opposed to just local users that ive added) ? I have downloaded both the password and shadow file. I have tried a few diffrent ways but continue to get 'file not found' The file is located in my downloads. It was a zip file i have unzipped and extracted to the download folder. the folder holds two files one is password one is shadow.

Explanation / Answer

you need to copy the password file. If system uses shadows pwds..then you can
use John "unshadow" utility.
use this commands:   
unmask 077
unshadow /etc/passwd /etc/shadow > mypasswd

the password file which you are trying to access might be accessed.
so you have to get /etc/passwd and shadow file, and then combine them into one file using unshadow
