SSH is a Swiss Army knife and Hogwart's magic wand all rolled into one simple command-line tool. As often as we use it, we sometimes forget that even our encrypted friend can be secured more than it...
Most of us longtime system administrators get a little nervous when people start talking about DevOps. It's an IT topic surrounded by a lot of mystery and confusion, much like the term "Cloud...

Sharing Admin Privileges for Many Hosts Securely

The problem: you have a large team of admins, with a substantial turnover rate. Maybe contractors come and go. Maybe you have tiers of access, due to restrictions based on geography, admin level or even citizenship (as with some US government contracts). more>>

Designing with Linux

3-D printers are becoming popular tools, dropping in price and becoming available to almost everyone. They can be used to build parts that you can use around the house, but more and more, they also are being used to create instruments for scientific work. more>>

Wondershaper—QOS in a Pinch

In past articles, I've discussed my BirdCam setup and how it automatically archives video footage from my bird feeders to YouTube every night. That's a really cool process, but unfortunately, it saturates my upstream bandwidth in the evening. more>>

Ideal Backups with zbackup

Data is growing both in volume and importance. As time goes on, the amount of data that we need to store is growing, and the data itself is becoming more and more critical for organizations. It is becoming increasingly important to be able to back up and restore this information quickly and reliably. Using cloud-based systems spreads out the data over many servers and locations. more>>

Non-Linux FOSS: Animation Made Easy

If you've ever wanted to make an animated film, the learning curve for such software often is really steep. Thankfully, the Pencil program was released and although basic, it provided a fairly simple way to create animations on your computer (Windows, Mac or Linux) with open-source tools. Unfortunately, the Pencil program was abandoned. more>>

diff -u: What's New in Kernel Development

David Drysdale wanted to add Capsicum security features to Linux after he noticed that FreeBSD already had Capsicum support. Capsicum defines fine-grained security privileges, not unlike filesystem capabilities. But as David discovered, Capsicum also has some controversy surrounding it. more>>

Android Candy: Disney Everywhere, Even Android!

As a father of three girls, I have piles and piles of Disney DVDs and Blu-rays. I occasionally look at the "Digital Copy" information and roll my eyes, because it requires some odd Windows DRM software or some other convoluted watching method that usually isn't possible or even interesting for me. more>>

Hats Off to Mozilla

Firefox turned ten years old last November and celebrated the occasion with a new version (33.1) that featured a much-welcomed developer edition. more>>

January 2015 Issue of Linux Journal: Security

Security: a Method, Not a Goal

The Security issue of Linux Journal always makes me feel a little guilty. It turns out that although I have a fairly wide set of technology skills, I'm not the person you want in charge of securing your network or your systems. By default, Linux is designed with a moderate amount of security in mind. For that, I am incredibly grateful. more>>

Purism Librem 15

I've been a fan of Free Software for quite some time, but for the most part I've found my opinions lean in the more pragmatic Bruce Perens Open Source camp.

As I write these words, the end of the year is approaching, and with it, so is the time for my annual book roundup.
