  • How to Install Mate Desktop Environment on EC2

    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.

  • How to Install and Use Wine on Linux

    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.

  • How to Setup an IPS (Fail2ban) to Protect from Different Attacks – Linux Hint

    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.

  • How to Use Docker to Create a Linux Developer Environment on Synology NAS? – Linux Hint

    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.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
