To interact with the system, whether remote or on-premises, we need some interface. There are two different types of interfaces to interact with the system, command-line interface (CLI) and graphical user interface (GUI). For beginners, a graphical user interface is much easier to use. The graphical user interface comes with different types of desktop environments like GNOME, KDE Plasma, MATE, Budgie, Xfce, Cinnamon, etc.

A Desktop Environment is the collection of components like icons, files, folders, etc. Different desktop environments provide different types of components like icons, files, and folders, etc. These environments determine what your operating system looks like and how you can interact with your operating system. Without a desktop environment, your operating system is just a terminal, and you can interact with your system using only commands.

MATE Desktop Environment is free and open-source software specially built for Linux and UNIX-like operating systems. The MATE project was forked and continued from GNOME2. In this article, we will set up the MATE Desktop Environment on our EC2 instance.

When Linux was first released, it lacked much of Microsoft Windows’s programs had successfully implemented, so the users were facing many complications. As a result, Wine was created by Linux, a compatibility layer that enables Windows programs to run on Linux. Wine could originally run only a few Windows programs, but now it can run hundreds of them, making it a versatile Linux system. You would assume that Wine might be difficult to install and use due to the difficulty of getting such a tool to life, but this is mistaken. Wine’s creators have gone to great lengths to make the accessibility layer as user-friendly as possible. Let’s look at installing and confining Wine on Ubuntu to use it to run Windows applications.

Discord is a text, image, video, and audio communication application designed for video gaming communities. This service is also becoming increasingly popular among non-gamers. In Discord, servers are a series of permanent chat rooms and voice chat platforms. Discord runs on different Linux distributions.

In this guide, we will see that how to install the Discord chat platform on Ubuntu 20.04.

Apache Tomcat is an open-source web application server optimized for serving Java-based content. Tomcat is used to run Java Servlets and serve web pages that contain JavaServer Pages (JSP) code.

This guide covers the installation of Apache Tomcat 9 server on Ubuntu 20.04.

In this article, we will take a look at how to use a break and continue in bash scripts. In bash, we have three main loop constructs (for, while, until). Break and continue statements are bash builtin and used to alter the flow of your loops. This concept of break and continue are available in popular programming languages like Python.

VMware Remote Console or VMRC is used to access VMware ESXi or VMware vSphere virtual machines remotely. You can manage your VMware ESXi or VMware vSphere virtual machines with VMRC as well.

IPS or Intrusion Prevention System is a technology used in network security to examine network traffic and prevent different attacks by detecting malicious inputs. Apart from just detecting malicious inputs as Intrusion Detection System does, it also prevents the network from malicious attacks. It can prevent the network from brute-force, DoS (Denial of Service), DDoS (Distributed Denial of Service), Exploits, worms, viruses, and other common attacks. IPS are placed just behind the firewall, and they can send alarms, drop malicious packets and block offending IP addresses. In this tutorial, we will use Fail2ban, which is an Intrusion Prevention Software package, to add a security layer against different brute force attacks.

The kill is a very useful command in Linux that is used to terminate the process manually. It sends a signal which ultimately terminates or kills a particular process or group of processes. If the user does not specify a signal to send with the kill command, the process is terminated using the default TERM signal.

Uname is a short form of Unix name. This is a very useful command in Linux, which provides hardware and software information in the current running system.

This short manual will show you how to get all system information through the Uname command.

Netstat is a command-line tool used by system administrators to evaluate network configuration and activity. The term Netstat is results from network and statistics. It shows open ports on the host device and their corresponding addresses, the routing table, and masquerade connections.

The purpose of this post is to show you how to install and configure different Netstat commands in Linux.

You can use the official Synology Virtual Machine Manager app to create a virtual machine, install any Linux distribution, and work on your development projects on the virtual machine. You can do the same in a Docker container using the official Synology Docker app. Although developing on a virtual machine is much more flexible than developing on a container (as a virtual machine is like a full-fledged computer), a virtual machine requires a lot of memory and system resources than a Docker container.

If your Synology NAS does not have enough memory or you don’t want to upgrade the memory of your Synology NAS, then you can use Docker to create a Linux development environment on your Synology NAS.

In this article, I am going to show you how to create a custom Ubuntu 20.04 LTS Docker image, create a container from it to set up a Linux development environment using Docker on your Synology NAS, and do remote development there with Visual Studio Code. So, let’s get started.

On Ubuntu 18.04 and later versions, there is a new way to set an IP address i.e., Netplan. This tutorial describes how to set an IP address from the command line on Ubuntu Linux by using the Netplan utility.

In this tutorial, we will show you how to install Chef Workstation on Ubuntu 20.04 LTS. For those of you who didn’t know, A Chef is a configuration management tool that simplifies the manual and repetitive tasks for infrastructure management. With the Chef users can easily manage, configure and deploy the resources across the network from the centralized location irrespective of the environment (cloud, on-premises, or hybrid). Chef Workstation comes with all the necessary packages and tools such as Chef-CLI, Knife, Chef Infra Client, and more.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by-step installation of the Chef Workstation on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.

Security first should be the thumb rule for any organization to secure your hard working code from hackers. It becomes more important while travelling application data over public network. For this situation, we need to implement end-to-end encryption using TLS.

Let’s Encrypt is an certificate authority provides valid SSL certificates to be used for web application. It provides certificate freely for everyone with some restrictions.

This tutorial describe you to how to setup Let’s Encrypt SSL with Tomcat web server.
