Fight the Good Fight with SmokePing

My Internet connection is unstable. I do realize ISPs generally claim some downtime is expected, and service is not guaranteed, and countless other excuses are common for intermittent service. I currently pay $120/month for business-class service, however, and I expect to get reliable Internet access on a regular basis. more>>

November 2013 Issue of Linux Journal: System Administration

Here at Linux Journal, we love system administrators. Partially, that's because many of us are system administrators, but more than that, we all realize just how important sys more>>

September 2013 Issue of Linux Journal: HOW-TOs

How'd Ya Do That?

I tend to read science fiction or fantasy for entertainment and/or escape from reality. more>>

Raspberry Strudel: My Raspberry Pi in Austria

I remember my first colocated server rather fondly. It was a 1U Supermicro that had been decommissioned from my employer after a few years' service. Although it was too old and slow for my company, the 800MHz CPU, 1GB RAM and 36GB SCSI storage was perfect for my needs back in 2005. A friend was kind enough to allow me to colocate the server at his facility for free. more>>

Raspberry Pi: the Perfect Home Server

Ever since the announcement of the Raspberry Pi, sites all across the Internet have offered lots of interesting and challenging uses for this exciting device.

More PXE Magic

In this article, I've decided to follow up on a topic I wrote about not in my column directly, but as a feature article called "PXE Magic" in the April 2008 issue. more>>

Dynamic DNS—an Object Lesson in Problem Solving

The other day in the Linux Journal IRC room (#linuxjournal on Freenode), I was whining to the channel about no-ip.com deleting my account without warning. My home IP address hadn't changed in a couple months, and because there was no update, it appeared abandoned. more>>

Home, My Backup Data Center

New Linux users often ask me "what is the best way to learn about Linux?" My advice always comes down to this: install and use Linux (any distribution will do but something stable works better), and more>>

Fabric: a System Administrator's Best Friend

Do you routinely make changes to more than a dozen machines at a time? Read this article to find out about a tool to make that task much easier. more>>

How to Deploy A Server

When I write my column, I try to stick to specific hacks or tips you can use to make life with Linux a little easier. Usually, I describe with pretty specific detail how to accomplish a particular task including command-line and configuration file examples. This time, however, I take a step off this tried-and-true path of tech tips and instead talk about more-general, high-level concepts, strategies and, frankly, personal opinions about systems administration. more>>

Troubleshooting with Telnet

Poor telnet, it used to be the cool kid on the block. It was the program all sysadmins turned to when they needed to connect to a remote server. Telnet just wasn't that good at keeping a secret—all communication went over plain text—so administrators started switching to SSH for encrypted remote shell sessions. more>>

Android System Administration Utilities

“Change is inevitable in a progressive society. Change is constant” Benjamin Disraeli 1867. Quite a fitting quote if I say so myself. When I started in systems administration back in the mid 90’s everything was done either remoted in from your desktop, a server, or you plugged a terminal into the back of the server. more>>

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.

Webinar
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.
