In this PDF file:[ENGLISH] [ICELANDIC] i show step-by-step how you can setup your own “Super computer cluster” using Ubuntu MPI Cluster from multiple machines with the goal of bruteforcing strong encrypted passwords with John the Ripper for academic purposes.
Owners of quad core machines will also benefit from my paper as the “john” binaries found in the Ubuntu Repositories are compiled to run on only one core.
I managed to decrease the time required to crack password hashes at home to a fraction (9% of the original time) using my 3 computers with this setup.
The paper is meant to be plain and simple aimed towards the average user, thus i choose not to implement NIS, NFS, BIND, and other more complex technologies.
A student should be able to setup and play with a computer cluster system at home without spend days reading through Linux systems-administrators books and manuals.
I make use of Ubuntu 10.04 as it is the most commonly used available Linux distribution today.
I suggest “MPI Programming” as the google keyword for those interested in learning how-to write programs for such systems.
