Tracking Server Uptimes

By Gene Liverman 

Unlike some other OS's, Linux almost never has to reboot… or so I was told when I first started learning about it. To illustrate the point, my mentor introduced me to an app that he ran on all of his servers called uptimed. more>>

Lock Firefox Prefs

Lock Firefox 6 Prefs (Also versions 3, 4, & 5)

By Shawn Powers 

In a corporate environment, it's often important to enforce Internet proxy settings for all users. Setting those options automatically is often difficult. Making them locked and immutable is even more difficult and poorly documented. Today we'll learn the basics, and from there you can customize Firefox as much or as little as you like. more>>

Creating a Centralized Syslog Server

By Jayson Broughton 

A centralized syslog server was one of the first true SysAdmin tasks that I was given as a Linux Administrator way back in 1997. My boss at the time wanted to pull in log files from various appliances and have me use regexp to search them for certain key words. At the time Linux was still in its infancy, and I had just been dabbling with it in my free time. more>>

iSCSI Lab

Creating Software-backed iSCSI Targets in Red Hat Enterprise Linux 6

By Pete Vargas Mas 

Studying for certification exams can be an adventure. Even more so when the certification exam is a hands-on, performance-based exam. The quandry most people I know fall into, is that to effectively study for such an exam, you need access to a lab environment with elements that may be beyond the scope of the average Linux enthusiast. One such element is iSCSI.  more>>

Archiving CDs to ISO from the Command Line

By Jayson Broughton 

A few weeks ago I was working on a PC when I needed to grab the motherboard driver CD.  In a perfect world, the CD would be located in a nice protective sleeve, safely kept away from the nasty elements that encompass the IT tech area (read: coffee, scratches, and the occasional jelly doughnut).  But in this case, it appeared someone had taken this CD and wiped it a more>>

Fun with ethtool

By Jayson Broughton 

Time to be honest here for a minute. The open source community really has outdone themselves coming up with some very obscure names for packages. Let's take this list of packages for instance: emacs, gimp, gcc, mutt, grub, kyle rankin, parted, tar, mutt, vim. Nine times out of ten, a common person is going to look at that list and become utterly confused over what package does what. more>>

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.
