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."

The nice thing about CentOS (and OpenSUSE IIRC) was how easy it was to just do a minimal server install.


Well, my point was that it's even easier with Ubuntu Server. It's entirely barebones *by default* and you don't get any additional stuff unless you chose to install it. Other than Slackware it's probably the most BSD-ish of Linux distros.
You should give it a try.

I hear people moan about Yast constantly but I can't say I ever had a problem with it.


I'm just a sucker for simplicity and vi, I guess. Plus Yast becomes obsolete as soon as you start doing serious configuration management.

But IIRC all I did in CentOS was select the 'minimal install' radio option. It was hardly a difficult process and I certainly wasn't there unticking all the programs and daemons I didn't want.
In fact one could even argue that CentOS had a few "default installs" and you just select which default profile you wanted.

In fact I seem to recall Ubuntu Server wasn't as "one click install" as you make out. I found there was still a lot of stuff pushed during the default install that I had to deselect (their cloud tools, auto-updates, etc).

However who even cares how few clicks a server install takes? You should only need to install the damn thing once. I don't even want to see the units reboot more than once a quarter - and even then only for critical kernel updates. So spending a little longer during the install is neither here nor there.

Other than Slackware it's probably the most BSD-ish of Linux distros.

You mean other than Slackware, Gentoo, ArchLinux.... :p

Seriously though I had installed Ubuntu Server last year and I really don't see what was BSD-ish about it. For one thing, it's the same SysV inits as Ubuntu desktop. One of the things that attracted me to ArchLinux was the elegance of it's BSD-like design - more so even then Slackware (not that I'm in anyway criticising the excellent work Patrick has done with Slackware). Ironically it's also more barebones than Ubuntu Server.


I don't mean this to slag off Ubuntu Server. It did surpass my preconceptions. But for me it just didn't bring enough to the table to make me want to switch my servers over.

Hmmm...can't recall seeing that option when installing CentOS 5.x but maybe it's just something I missed. I quickly learned NOT to select the "Server" install though.

Welk. I mean in terms of minimalism. Naturally it still have the SysV stuff. Also I am comparing it to monstroisities like RHEL, Centos and SUSe ;)
It is of course not as simple and elegant as OpenBSD.

found there was still a lot of stuff pushed during the default install that I had to deselect (their cloud tools, auto-updates, etc).


Nope, they're all deselected during the install and you have to manually select them.

However who even cares how few clicks a server install takes? You should only need to install the damn thing once.


Those of us who install a lot of servers care ;) . Well, not that much really I just like the fact that I dont have to deselect anything during the install.


excellent work Patrick has done with Slackware


Yep, Slackware is awesome although I do find the lack of proper package management more of a con than a pro.
