Ubuntu, Kubuntu, Xubuntu "In this post 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 this setup 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 using this setup."

It's only real difference...
Is the Setup and kernel it uses.
Otherwise it uses same same everything.

There's quite a bit difference. For one, Ubuntu Server doesn't come with Xorg and thus no XWindows apps. Ubuntu, on the other hand, doesn't even come with OpenSSH-server pre-installed.

I mean realistically, half the time the only thing that separates one distro from another is what comes pre-installed. Particularly when tutorials like these are easily transferable from one Linux to another.
