Create a Mini PC or Server with Olimex's Olinuxino A13/A13Micro

Olimex is a Bulgarian company known for its innovative hobbyist products. It has a wide array of microcontroller-based products, ranging from the small Arduino clones to the very able system that has the Allwinner A13 microcontroller as its brain. In this article, I describe how you can create a working Linux system for the Olinuxino A13 and Olinuxino A13Micro from scratch. more>>

Protect Your Ports with a Reverse Proxy

In a previous article, I discussed Apache Tomcat, which is the ideal way to run Java applications from your server. I explained that you can run those apps from Tomcat's default 8080 port, or you can configure Tomcat to use port 80. But, what if you want to run a traditional Web server and host Java apps on port 80? The answer is to run a reverse proxy. more>>

Advanced Hard Drive Caching Techniques

With the introduction of the solid-state Flash drive, performance came to the forefront for data storage technologies. Prior to that, software developers and server administrators needed to devise methods for which they could increase I/O throughput to storage, most of which resulted in low capacity caching to random access memory (RAM) or a RAM drive. more>>

Unboxing Day

As much as I love working with Linux and configuring software, one major part of being a sysadmin that always has appealed to me is working with actual hardware. There's something about working with tangible, physical servers that gives my job an extra dimension and grounds it from what might otherwise be a completely abstract job even further disconnected from reality. more>>

Remotely Wipe a Server

In many ways, I feel sorry for people stuck with proprietary operating systems. When something goes wrong or if they have a problem to solve, the solution either is obvious, requires buying special software or is impossible. With Linux, I've always felt that I was limited only by my own programming and problem-solving abilities, no matter what problem presented itself. more>>

It's Always DNS's Fault!

It's always better to learn from someone else's mistakes than from your own. In this column, Kyle Rankin or Bill Childers tells a story from his years as a systems administrator, and the other chimes in from time to time. It's a win-win: you get to learn from their experiences, and they get to make snide comments to each other. Today's episode is narrated by Bill. more>>

Nagging Notifications

In the February 2011 issue, I wrote about screen, the console window manager, and how I configure its hardstatus line to show notifications along the bottom of my terminal window. more>>

Consolidate: Put Your Servers into a VirtualBox VM

Rather than installing a server, such as a web server, directly onto your main computer, why not install it in a VM? This sort of setup has a few advantages of security and convenience. These days, spreading resources out into the cloud is the in-thing, but consolidation is often underexploited. Hosting a server in a virtualizer such as VirtualBox is often a good approach for casual or occasional server needs on a home network. more>>

Using an SMS Server to Provide a Robust Alerting Service for Nagios

I’m a big fan of the Nagios network monitoring system and rely on it to tell me if something goes wrong with the systems for which I am responsible. I have made a large investment in time configuring Nagios to monitor exactly what I am interested in, and this effort would be wasted if Nagios detected a problem, but failed to communicate that problem to me. more>>
