Linux Journal Issue #189/January 2010
You say potato, I say potahto, you say ham, I say amateur... you see where I'm going with this? Ok, maybe not, Amateur Radio, that's where and that's what this month's issue focus is. What you might ask is the connection between Amateur Radio and Linux? Well Linux may be the only O/S out there with an AX.25 packet radio protocol driver, and it's had it since forever. So blow the dust off your license and start reading. If Ham's not your favorite food, don't despair there are plenty of other articles in this month's issue including, but not limited to, Firewall Builder, Cucumber, Vimperator, port knocking with knockd, building appliances with Linux and Xen, and using Twitter from the command line.

Now Data Gets Personal
In Every Issue
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.

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.

Free Webinar: Linux Backup and Recovery
Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.
In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
