Systems Management
Monitoring, recovery, and precise logs can often do more to reduce your number of outages and limit the scope of system failures than the typical panacea more hardware, more software, and more hot spares.
Need a system or two to validate a new architecture? When combined with Linux, VMware Server provides a sophisticated and highly adaptable infrastructure that allows you to test complex customer client-server software configurations on a single machine.
A number of old-fashioned tools can prevent very
modern problems
What if you have only one computer, and you want to be able to run Linux as well
as Windows? Well, you can -- through something called dual booting. Dual booting is an either/or
proposition. You can't really run Windows and Linux at the same time. This month's column will be of most
use to Windows 3.x/95/98 users. If you're running NT, you should purchase the commercial product,
Security
Intrusion detection is critical for network security. Use Bro to catch miscreants red-handed.
SNORT looks for intrusions, while ACID can help you make sense of what’s happened after an intrusion.
Document and image scanners have become an integral part of many offices. With a scanner, you can quickly digitize photos, diagrams, and even textual documents for electronic alteration and distribution.
As several recent high profile compromises have reminded us, Linux isn't immune to security vulnerabilities. While you should always do everything you can to secure your Linux systems, you can also put measures in place to quickly detect a break-in. One useful "alarm" system is Tripwire.

Being technical, you're probably eager to jump into the "how" of virt. But let's take a step back for a minute and look at just "what" this technology is.
The rise of non-Windows operating systems in the enterprise and the easy availability of powerful hardware is killing the "one OS for one box" model. This is a good thing because it allows users to easily work with, test on, and develop for multiple operating systems. And the best way to accomplish this is with virtualization.
If you already have a Windows PC, you can install Linux and run your existing Windows configuration as a virtual machine. Jason Perlow explains how to do it.
How would you like to run several operating systems at once on the same physical hardware with virtually no performance overhead - and for free? That's the promise and the purpose of Xen, a relatively new open source project that turns one piece of hardware into many, virtually. If you're looking to cut costs or maximize usage or both, follow the path to Xen.
A Linux Virtual Server cluster is a highly-scalable and highly-available network service cluster built on a set of real servers. Here's how they work, and how you can set one up yourself.
Xen 3.0 provides vastly improved stability and a wealth of new features. Xen 3.0 also supports unmodified operating systems and enterprise hardware. Here’s a look at the latest version-- one that’s ready for production environments.
Remember when the hot machine for running Linux was an Intel 486? Or a Pentium III? For most of us, single-chip Intel PCs are still the computers of choice. It's what we play on, what we work on, and what we develop on.
Why can't the virtualization vendors just get along?
