What kind of passwords can John the Ripper crack?

How to check if root password got cracked?
To check if the root password got cracked, filter by UID: Just as you can filter by user, you can also filter by group, by using the –groups flag, and that filtering is available also when cracking. Going further to wordlist mode, here’s how you can use it with the built-in mangling rules enabled:
Which is the best way to crack a password?

What’s the best way to crack John the Ripper passwords?
John the Ripper’s primary modes to crack passwords are single crack mode, wordlist mode, and incremental. The single crack mode is the fastest and best mode if you have a full password file to crack. Wordlist mode compares the hash to a known list of potential password matches. Incremental mode is the most powerful and possibly won’t complete.
Do you need to run John the Ripper as root?
No further commands will need to be run as root. If your system is ancient enough that it keeps passwords right in the world-readable /etc/passwd, simply make a copy of that file. If you’re going to be cracking Kerberos AFS passwords, use John’s “unafs” utility to obtain a passwd-like file.
