Back a few months ago, we did a feature poll on our MAAS forum, and the most-requested new feature turned out to be “Recommission/rescan a machine after it has been deployed“. With the release of MAAS 3.1, we’ve added that feature, making MAAS an even better choice for linux deployment tools. Here’s a sample of how it works.

AlmaLinux is tagged as a forever-free Linux Operating System Distribution because of the numerous benefits it has to offer to its user community. If you were too attached to CentOS before it got discontinued, think of AlmaLinux as its renamed and continued OS version.

How do I create an HTTPS server for Node Js? This is the most frequent question asked by node js developers. For various security reasons, many popular modules ask to enable HTTPS protocol.

What is HTTPS protocol? If you remove S from HTTPS, we get HTTP, which is a standard protocol for accessing web applications. It’s not secure; anyone can intercept your data packets connected to the same network.

While HTTPS is a secure protocol for web applications, here, all the communication between your browser and server is encrypted and decrypted by only using a private key. This makes communication more secure and private.

In a previous article we talked about listening and extracting the content of an initramfs image using standard, simple tools like gzip, dd and cpio or with dedicated scripts like lsinitramfs, lsinitrd and unmkinitramfs. In this tutorial we learn how to (re)build an initramfs on Linux using dracut.

Sharing files is an essential part of server administration. It allows sharing of resources across the network which are needed by users to carry out their tasks. One of the widely used file-sharing software is Samba.

Samba, a re-implementation of the popular SMB (server message block) protocol, is a stable and free application that allows sharing of files and print services across a network. The software is installed on a central Linux server from which shared files can be accessed from both Linux and Windows systems.

In this guide, we will walk you through the installation of the Samba Server on RHEL-based distributions such as CentOS Stream, Rocky Linux, and AlmaLinux.

In this guide we are going to explore how to install Java Runtime Environment (JRE) and the Java Developer Kit (JDK) in OpenSUSE Leap 15.3 system.

Java and the JVM (Java’s virtual machine) are required for many kinds of software, including Tomcat, Jetty, Glassfish, Cassandra and Jenkins.

Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. Java was developed by Sun Microsystems (which is now the subsidiary of Oracle) in the year 1995. James Gosling is known as the father of Java.

In this guide we are going to explore how to install Java Runtime Environment (JRE) and the Java Developer Kit (JDK) in FreeBSD 13 system.

In this tutorial, I will show you how to install the Envoy proxy server on Ubuntu 20.04.

Envoy is an L7 proxy and communication bus designed for large modern service-oriented architecture. The project was born out of the belief that the network should be transparent to applications. When network and applications problems occur, it should be easy to determine the source of the problem.

Envoy is an open-source edge and service proxy, designed for cloud-native applications.

In this guide we are going to Install and set up Apache virtual host to serve PHP content on a Debian 11 system.

Nextcloud 23 brings a major overhaul to the platform and introduces Nextcloud Office and plenty of other features and fixes to make it an outstanding choice for anyone looking to host a full-fledged cloud service in-house (in your data center, your cloud-hosted provider or even on a server in your home).

In this video, I am going to show how to install Kali Linux 2021.4.

Suppose we have our Linux system setup with an almost-full disk encryption, with only the /boot partition unencrypted. Assuming we achieved encryption by using a LUKS container, we need the appropriate software to unlock it at boot. This software, however, is part of the encrypted system. Since the Linux 2.6 series, the solution to this, and other similar problems, is called initramfs (Initial ramfs). In this article we see how an initramfs is composed and how to extract or list its content.

In this tutorial, we are going to learn how to upgrade Linux Kernel to 5.16 on Ubuntu 20.04.

Linux Kernel is a free and open-source, monolithic, modular, multitasking Unix-like operating system. It is the main component of a Linux operating system and is the core interface between the computer’s hardware and its processes. It makes communication possible between computer hardware and processes running on it and it manages resources effectively.

Linux 5.15 mainline was released recently by Linux Torvalds with better new features to try out. The mainline tree is maintained by Linus Torvalds and It is where all new features are added and releases always come from.

As your business grows, you'll probably find yourself needing to manage customer relations. With such a platform available to your business, your staff can better manage their clients, customers, opportunities, leads and much more.

I'll walk you through the process of installing the open-source SuiteCRM platform, one that focuses on sales, marketing and services administration.

The only things you need to make this work are a running instance of Ubuntu Server and a user with sudo privileges. With those things at the ready, let's get to work.

This vulnerability has the highest CVSS score of 10.0, so you need to pay attention. One of the big problems is knowing if you're vulnerable. This is complicated by the many ways Log4j can be deployed. Are you using it as part of a Java project, is it rolled into a container, did you install it with your distribution package manager, and (if so) which log4j packages did you install? Or did you install it from source? Because of this, you might not even know if your server is vulnerable.

Fortunately, for Linux servers, GitHub user, Rubo77 created a script that will check for for packages that include vulnerable Log4j instances. It's in beta, and it's not one 100%, but it's a great place to start. Understand, this script doesn't test for jar files that were packaged with applications, so do not consider it anything more than a launching point to start your forensics.

I tested this script against a server that I knew had a vulnerable Log4j package installed, and it correctly tagged it. Here's how you can run that same script on your Linux servers to find out if you might be vulnerable.

Has a backlit keyboard in your PC? This extension makes possible to control the backlight brightness by adding a slider bar into upper right corner system tray menu in GNOME desktop.

Under system volume and screen brightness sliders, it adds a third slider bar allows to easily control the keyboard backlight.

In this article, we will see how to create your first deployment on a Kubernetes Cluster. As an example, we will create a deployment for NginX.

Once we have a running Kubernetes cluster, we can deploy our containerized applications on top of it. We can create a Kubernetes Deployment configuration to achieve this.

A Deployment provides declarative updates for Pods and ReplicaSets. We describe a desired state in the Deployment and the Deployment Controller changes the actual state to the desired state at a controlled rate.

The Web Terminal Operator in Red Hat OpenShift provides a web terminal with common cluster tooling pre-installed. The operator gives you the power and flexibility to work with your product directly through the OpenShift web console, eliminating the need to have all your tooling installed locally.

This article is an overview of the new features introduced in Web Terminal Operator 1.4. One of the most important improvements is that you can now install the Web Terminal Operator in any namespace. In addition, our tooling has been updated to be compatible with OpenShift 4.9.

We will edit CentOS 8 the GRUB2 configuration parameter and change it using grubby to boot with old kernel or to change the default boot entry for kernel in the system.

Grubby is a command line tool for updating and displaying information about the configuration files for various architecture specific bootloaders. It primarily designed to be_used from scripts which install new kernels and need to find information about the current boot environment.

Grubby will use these default settings to search for an existing configuration. If no bootloader configuration file found, grubby will use the default value for that architecture.
