Secure Server Deployments in Hostile Territory

Would you change what you said on the phone, if you knew someone malicious was listening? Whether or not you view the NSA as malicious, I imagine that after reading the NSA coverage on Linux Journal, some of you found yourselves modifying your behavior. The same thing happened to me when I started deploying servers into a public cloud (EC2 in my case). more>>

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>>

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>>
