I first tried to install this from the tarball available on the openwall site. There are several dependencies that you need before attempting to build: sudo dnf install openssl openssl-devel gcc You may not have access to the Internet because your network firewall / proxy is trying to mitm – in my case I fixed this by shouting over to the firewall guy in the office.Īs I need support for a large variety of hash formats the version of John in the Fedora repositories is useless to me, instead I am using the community enhanced edition. On a side note, if when running dnf commands you encounter an error like: Error: Failed to synchronize cache for repo 'updates' from '': Cannot prepare internal mirrorlist: Curl error (60): Peer certificate cannot be authenticated with given CA certificates for I’m using Fedora 23 Server on each of the hosts, have configured a static IP address using the Cockpit interface on port 9090 (i.e and created a user which will be used to authenticate between the hosts. I hope this (rambling) guide is useful to others as well as my future self.

There are several guides online dictating how to achieve this kind of setup using Kali or Ubuntu, but I prefer Fedora so had to alter a lot of the commands to suit and I encountered some odd errors along the way. This is a first for me so I thought I had better document how I did it for when it all burns to the ground and I have to start again. I therefore decided my best bet for maximum hash cracking goodness would be to use John in parallel across all these machines. I didn’t have any money to invest in this project, so I am using whatever servers and workstations are lying around unused in the back of the server room. I recently started building a new dedicated rig with the sole purpose of cracking passwords. John the Ripper is an excellent password cracking tool that I regularly use during penetration tests to recover plaintext passwords from multiple hash formats.
