HOW-TOs

September 2014 Issue of Linux Journal: HOW-TOs

How'd You Do That?

Open-source advocates tend to make for rotten magicians. more>>

Considering Legacy UNIX/Linux Issues

Gah, so frustrating! Ten years ago I wrote a rather popular book called Wicked Cool Shell Scripts, and I'm working on a new edition—a Tenth Anniversary release. There are lots of new scripts, entirely new chapters and updates to the older stuff. more>>

Security Hardening with Ansible

Ansible is an open-source automation tool developed and released by Michael DeHaan and others in 2012. DeHaan calls it a "general-purpose automation pipeline" (see Resources for a link to the article "Ansible's Architecture: Beyond Configuration Management"). more>>

Monitoring Android Traffic with Wireshark

The ubiquity and convenience of smartphones has been a real boon for getting information on the go. more>>

Tails above the Rest, Part III

In my first two columns in this series, I gave an overview of Tails, including how to get the distribution securely, and once you have it, how to use some of the basic tools. more>>

rc.local, Cron Style

Occasionally as seasoned Linux users, we run across simple things we never knew existed—and are amazed. Whether it's tab autocompletion, sudo !! for when you forgot to type sudo or even recursive file listing with ls, the smallest tricks can be so incredibly useful. Not long ago, I had one of those moments. more>>

Resizing Images with ImageMagick

Sure, you can open up a graphics program like GIMP and resize an image, but what if you want to resize 10, 50 or 200 images? ImageMagick's convert program is just what you need. more>>

A Little GUI for Your CLI

I've tried pretty much every IRC client available for both Linux and OS X. (I use both platforms during my day job.) No matter how many times I try to find a GUI application that meets my needs, I always turn back to Irssi. more>>

TogetherJS

Want to add real-time collaboration to your Web application? Mozilla's TogetherJS is worth a look. more>>

Command-Line Cloud: rss2email

In my last article, I started a series called Command-Line Cloud. The intent of the series is to discuss how to use the cloud services we are faced with these days without resorting to a Web browser. I spend most of my time on the command line, so that's where I'd most like to interface with cloud services. more>>

Two-Factor Authentication System for Apache and SSH

If you run a publicly accessible Web server for your own use (and let's face it, if you're reading Linux Journal, there's a very good chance you do), how do you go about limiting the risk of someone accessing your site and doing bad things? How about SSH, an even bigger concern? 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>>

Be a Mechanic...with Android and Linux!

"Check Engine Soon"—that little orange light on your car's instrument panel is possibly one of the more annoying things about modern automobiles. Ever had it pop on during a trip and wonder whether it was just something mundane, like your gas cap being loose, or whether it's something deathly serious and a piston could come shooting out the side of your engine block at any time? more>>

Compojure

In my last article, I started discussing Compojure, a Web framework written in the Clojure language. Clojure already has generated a great deal of excitement among software developers, in that it combines the beauty and expressive elegance of Lisp with the efficiency and ubiquity of the Java Virtual Machine (JVM). more>>

Two Pi R

Although many people are excited about the hardware-hacking possibilities with the Raspberry Pi, one of the things that interests me most is the fact that it is essentially a small low-power Linux server I can use to replace other Linux servers I already have around the house. 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.
