system administration encompasses managing the software and hardware of Linux systems, which can be complex, especially for those new to Linux or managing multiple systems. Fortunately, Webmin, a web-based interface, simplifies many of the routine tasks involved in maintaining a healthy Linux system.

Linux Journal Deputy Editor and longtime software developer, Bryan Lunduke isn't entirely sure, so he asks some experts to help him better understand the DevOps phenomenon. The word DevOps confuses me. I'm not even sure confuses me quite does justice to the pain I experience—right in the center of my brain—every time the word is uttered. </div> </div> </article> </div> <div class="views-row"><article data-history-node-id="1340729" role="article" about="/content/my-favorite-infrastructure" class="story is-promoted teaser clearfix"> <div class="teaser-image"> </div> <div class="teaser-text"> <h2> <a href="/content/my-favorite-infrastructure" rel="bookmark"> <span>My Favorite Infrastructure</span> </a> </h2> <footer> <div class="author"> <span><a title="View user profile." href="/users/kyle-rankin" lang="" about="/users/kyle-rankin" typeof="schema:Person" property="schema:name" datatype="">Kyle Rankin</a></span> - August 7, 2019 </div> </footer> <div class="content-body"> Take a tour through the best infrastructure I ever built with stops in architecture, disaster recovery, configuration management, orchestration and security. </div> </div> </article> </div> <div class="views-row"><article data-history-node-id="1340199" role="article" about="/content/bare-bones-monitoring-monit-and-rrdtool" class="story is-promoted teaser clearfix"> <div class="teaser-image"> </div> <div class="teaser-text"> <h2> <a href="/content/bare-bones-monitoring-monit-and-rrdtool" rel="bookmark"> <span>Bare-Bones Monitoring with Monit and RRDtool</span> </a> </h2> <footer> <div class="author"> <span><a title="View user profile." href="/users/andy-carlson" lang="" about="/users/andy-carlson" typeof="schema:Person" property="schema:name" datatype="">Andy Carlson</a></span> - March 21, 2019 </div> </footer> <div class="content-body"> How to provide robust monitoring to low-end systems. </div> </div> </article> </div> <div class="views-row"><article data-history-node-id="1340436" role="article" about="/content/redefining-landscape-system-monitoring-interview-pulseways-founder" class="story is-promoted teaser clearfix"> <div class="teaser-image"> </div> <div class="teaser-text"> <h2> <a href="/content/redefining-landscape-system-monitoring-interview-pulseways-founder" rel="bookmark"> <span>Redefining the Landscape of System Monitoring: an Interview with Pulseway's Founder</span> </a> </h2> <footer> <div class="author"> <span><a title="View user profile." href="/users/petros-koutoupis" lang="" about="/users/petros-koutoupis" typeof="schema:Person" property="schema:name" datatype="">Petros Koutoupis</a></span> - January 25, 2019 </div> </footer> <div class="content-body"> Pulseway provides a product of the same name that's built to enable IT personnel and give them the ability to monitor, manage and automate their systems and the tasks or applications that they host.

At lot has changed since then, and nowadays, you can use a standard Linux desktop without ever having to open a terminal or use old UNIX services.

Early in my career, I was responsible for managing a large fleet of printers across a large campus. We're talking several hundred networked printers. It often required a 10- or 15-minute walk to get to some of those printers physically, and many were used only sporadically. I didn't always know what was happening until I arrived, so it was anyone's guess as to the problem. Simple paper jam? Driver issue? Printer currently on fire? I found out only after the long walk. Making this even more frustrating for everyone was that, thanks to the infrequent use of some of them, a printer with a problem might go unnoticed for weeks, making itself known only when someone tried to print with it. </div> </div> </article> </div> <div class="views-row"><article data-history-node-id="1340145" role="article" about="/content/have-plan-netplan" class="story is-promoted teaser clearfix"> <div class="teaser-image"> </div> <div class="teaser-text"> <h2> <a href="/content/have-plan-netplan" rel="bookmark"> <span>Have a Plan for Netplan</span> </a> </h2> <footer> <div class="author"> <span><a title="View user profile." href="/users/shawn-powers" lang="" about="/users/shawn-powers" typeof="schema:Person" property="schema:name" datatype="">Shawn Powers</a></span> - October 16, 2018 </div> </footer> <div class="content-body"> Ubuntu changed networking.
