Readers' Choice Awards 2011

The votes are in, the tallies are counted, the hanging chads have been evaluated, and we have our winners. This year holds a few surprises, a couple dominant players and as much open source as you can handle. We don't encourage gambling here at Linux Journal, but if you had an office pool going for pizza money, it's officially too late to make your wager.

The Lustre Distributed Filesystem

There comes a time in a network or storage administrator's career when a large collection of storage volumes needs to be pooled together and distributed within a clustered or multiple client network, while maintaining high performance with little to no bottlenecks when accessing the same files. That is where Lustre comes into the picture. The Lustre more>>

Getting Help From Linux - Part 2 Info

Well here we are again, at part two of the 'Getting Help from Linux' series.  In this blog post I'll be talking about using Info to get help from Linux.  In my previous post I spoke about how Info came about, but just in case you missed it I'll give you another quick lesson.  Gnu more>>

Tracking Server Uptimes

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)

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

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>>

Oooh, I just know I'm going to hear it in the comments for that one. But you know what? Just how many of you have tried something similar with other words? You know you have at least once or twice. Go ahead, try one or two..you might be surprised.

iSCSI Lab

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

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

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

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>>

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

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.
