Ethernet Masked Ball

I would like to be able to modify the MAC ID of my Ethernet card in much the same way I can with my Linksys router. Is there an easy way to do this?

—Mike O'Doherty, mgi1356@motorola.com

You didn't specify which Ethernet card you have; some allow this, while others do not. If your card does allow this, you can use ifconfig as follows:

ifconfig eth0 hw ether 001122334455

For those using cable or DSL modems, note that this is a useful trick if you have set up your service using a Windows box and want to install a Linux firewall/gateway. Most providers track the MAC address of the workstation's Ethernet card and can be hard to deal with if this changes. With the above command, you can force your Linux gateway to have the same MAC address as your original client system.

Touch Me, It's So Easy to Leave Me...

What is the required XF86Config-4 setup to use a Dynapro (3M) touchscreen? Do I need to enable it with something similar to xsetpointer NFI3 after X starts?

—Shane Kennedy, skenn@indigo.ie

You can find updated drivers for 3M (formerly Dynapro) touchscreens at www.cdp1802.org/mmmtouch.

Fabric-Based Computing Enables Optimized Hyperscale Data Centers

Today’s modular x86 servers are compute-centric, designed as a least common denominator to support a wide range of IT workloads. Those generic, virtualized IT workloads have much different resource optimization requirements than hyperscale and cloud applications. They have resulted in a “one size fits all” enterprise IT architecture that is not optimized for a specific set of IT workloads, and especially not emerging hyperscale workloads, such as web applications, big data, and object storage. In this report, you will learn how shifting the focus from traditional compute-centric IT architectures to an innovative disaggregated fabric-based architecture can optimize and scale your data center.

Red Hat White Paper: Using an Open Source Framework to Catch the Bad Guy

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6

Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.
