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."

Trying != run in production for a long time. As someone who has actually run ubuntu Server in production for years without any problems I seriously contend that "it's not stable enough".

Happy with the distro upgrades?
(It's a honest question)

Since it's production I use LTS so distro upgrades aren't that common. Havent had any problems with them though.

There are some issues with using ubuntu as server distro, including hardware certification and tech support. Enterprise distros may seem boring but they go through hell lot more QAs and certifications and take bugs found on supported hardware pretty seriously.

I've seen quite some headaches people were having with ubuntu with completely generic dell servers certified for RHEL and SLES. Their solution? Just try installing different versions of ubuntu and use whatever which doesn't crash. It almost felt surreal. :-(
