I am a linux noob trying to use john the ripper for a security class. I have John installed to usr/share/john and i have (I think) successfully used the unshadow command to unshadow the pw file and then move a copy of the unshadowed file to usr/share/john
sudo /usr/sbin/unshadow /etc/passwd /etc/shadow > /tmp/crack.password.db sudo cp tmp/crack.password.db usr/share/john/crack.password.db
But when I try to run john crack.password.db, I get the following error message:
myName@ubuntu: usr/share/john$ sudo john crack.password.db No "single crack" mode rules found in john.ini
- When I open "John.ini" in a text editor, it is blank.
What does this message mean and how can I fix it?
