The Simple Network Management Protocol (SNMP) has been an integral part of monitoring network environments since its introduction in 1988. It has established itself as the de facto standard in network monitoring. Many manufacturers support the protocol and have implemented an SNMP agent on their network devices. These agents allow monitoring solutions to query various data, such as bandwidth, CPU load, network interfaces, etc., without installing an additional agent on network equipment. 

By: Pedro A. Aranda Gutiérrez This article shows how to configure and use the org-mode provided by Emacs to produce pretty documents. org is a multi-purpose structured text file format and Emacs can translate it to LaTeX files which, in turn, can be translated into pretty PDF documents, taking advantage of all the typesetting facilities provided by LaTeX. This is a compendium of tricks evolved out of the experience of working with Emacs, org-mode and LaTeX.

The ability to write code is a huge differentiator for every job role in an enterprise Linux environment. As an Operations and DevOps manager, I was constantly challenged to improve my team’s programming skills, and the team genuinely wanted to be more proficient. But how? Structured training is a standard answer: take a course! Our company, like many, invested enormously in learning resources. I’d sit with an engineer one-on-one and we’d ponder the online portal together, puzzling out the most appropriate Python learning path.

Modern solutions must be designed resiliently to enable service provisioning during incidents. There are multiple solutions to develop high-available and reliable services that can be applied to various levels in a system’s architecture and design. Some programming languages are specifically designed to meet these challenges. The functional programming language Erlang provides inherent functionality to develop these resilient services. Therefore, this article presents the exemplary design and development of a communication service based on the Internet Relay Chat (IRC) protocol in Erlang to investigate its availability features.

TACACS+ server implementation for Linux operating system, although neat, lacks a graphical user interface which makes daemon configuration a smooth and intuitive process. In the next few paragraphs, we will discuss how to configure the TACACS+ daemon on Linux operating system and demonstrate how to deploy a simple, yet intuitive, GUI used for the configuration of the TACACS+ instance.

Google Chrome is a widely used web browser in the world. Google Chrome is fast and secure as well. However, it is not an open-source web browser. Hence, Debian comes with a pre-loaded Chromium browser, and not a Chrome. Chromium is an open-source browser. If you still want to install the Google Chrome browser on Linux, this article is for you. Installing Chrome on Linux has a little twist as it’s not an open-source browser. So let’s check out how you can easily install Chrome browser from a Linux terminal.

Linux might sound scary for first-time Linux users, but actually, it isn’t. Linux is a bunch of open-source Unix operating systems based on Linux Kernel. These operating systems are called Linux distributions, such as Fedora, Debian, Ubuntu, and Mint. This article presents a guide to 7 important Linux commands for every Linux user to know. So, let’s begin.

PuTTY is one of the oldest and most popular SSH clients, originally for Windows, but now available on several platforms. It has won corporate support and endorsement, and is prepared and bundled within several third-party repositories.

I have suffered from distrohopping. Now that I have settled for the last two years, here are some tips to save your time. All distros run the same operating system at their core, Linux. They are more similar than different. Hence, the marginal cost (time) of looking for a better distro is much more than the marginal benefit of it.

Not only the Linux distros are open-source but the apps for Linux are also free. Though some business apps come with a cost, most of the apps created for individuals don’t have any charges. Want to know about some of the cool apps to download on your Linux machine? This article walks you through 7 apps to download on Linux to make your life easier. Head over to the next section!  

Checking the battery status through GUI is easy. Hovering the mouse cursor over the battery indicator given in the Laptop task bar simply shows the battery level. But, did you know you can find the battery status through the Linux command line as well? Yes, there are some utilities in Linux that can be of help in this regard. This article explains 4 different methods of checking laptop battery status using the Linux command line.

Decreasing video sizes becomes necessary when space is limited in cloud services, disks, or personal storage drives. You can easily hold onto larger files by chopping them down to a lower size. The world of open-source video editing tools is huge. So, choosing one can be tricky. This article explains how you can efficiently decrease video sizes using FFmpeg in Linux.

This article will give you an overview of replacing a variable value in a file using SED. Before replacing a variable in a file using SED, you need to understand what SED is, the syntax of SED, and how SED works.

Do you want to create a Shell script in your Linux system?

But before heading over to creating a shell script, let’s understand what Shell scripting in Linux is. What is Shell Scripting in Linux? So, what’s Shell scripting?

Detecting vulnerabilities and managing the associated patching is challenging even in a small-scale Linux environment. Scale things up and the challenge becomes almost unsurmountable. There are approaches that help, but these approaches are unevenly applied. In our survey, State of Enterprise Vulnerability Detection and Patch Management, we set out to investigate how large organizations handle the dual, linked security concerns of vulnerability detection and patch management.

Reproducible builds are one of the tools that can help developers to implement live patching consistently and safely. In this article, I explain why reproducible builds matter for live patching, what exactly reproducible builds are, and how containers are coming to the rescue.
