An excellent Linux dedicated server that won't burn a hole in your pocket

[img_assist|nid=1286|title=|desc=|link=none|align=left|width=234|height=252]This site certainly has seen it's share of hosting environments. It started on a shared hosting, without even a proper domain name, then later moved among many of the popular virtualization techniques, first VMware server, then KVM and finally Xen (VPS). But, most of that time, it somehow wanted to end on a real hardware, to have a room to breathe, so to say.

How S.M.A.R.T. are your disks?

GSmartControl is a graphical user interface for smartctl (from Smartmontools package), which is a tool for querying and controlling S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) data on modern hard disk drives. It allows you to inspect the drive's S.M.A.R.T. data to determine its health, as well as run various tests on it.

Building Debian FreeRadius package with EAP/TLS/TTLS/PEAP support

Debian's FreeRadius package is built without support for EAP/TLS/TTLS/PEAP because of the licensing problems of the OpenSSL library. But, if you want to implement 802.1x network authentication with strong security, you'll need it. This is a short tutorial that explains how to build Debian (sid aka unstable) package linked to libssl and with EAP/TLS/TTLS/PEAP support compiled in.

Finally user-friendly virtualization for Linux

The upcoming 2.6.20 Linux kernel is bringing a nice virtualization framework for all virtualization fans out there. It's called KVM, short for Kernel-based Virtual Machine. Not only is it user-friendly, but also of high performance and very stable, even though it's not yet officialy released. This article tries to explain how it all works, in theory and practice, together with some simple benchmarks.

A little bit of theory

The difference between Xen & VMware

Virtualization is a hot topic these days. With hardware getting more and more capable, by means of cheap multi-core processors and gobs of memory, we can expect virtualization to become only more important in the coming years. Virtualization promises reduced costs for IT organizations, both hard (machines, power, cooling) and soft (admin and operations personnel).
