  • How to install Linux on your Windows PC | ZDNet

    First, download the newest version of Linux Mint. As I write this, that's Mint 20.2, but Linux Mint 20.3 will be out in early 2022. At about 1.5GB, depending on your internet speed, this may take a while.

    Mint comes with three different desktop interfaces. These are MATE, Xfce, and its default desktop, Cinnamon. I recommend you go with Cinnamon, for starters. If it turns out you really want to get deep into Linux, you'll have plenty of opportunities to explore the various Linux interfaces.

    Once you've downloaded Mint, you should try the Linux distro before installing it. Fortunately, unlike other operating systems, Linux distros like Mint make it easy to give them a test run before committing to it.

    If you don't have an ISO burner program, download one. I recommend freeware programs ImgBurn for optical drives and Yumi for Windows for USB sticks. Other good choices are LinuxLive USB Creator and UNetbootin. These are all free programs.

    Unless you're using an older PC that won't boot from a USB stick, I strongly recommend using a USB flash drive for your test drive. You can run Linux from a DVD, but it's very slow. But, I might add, Linux Mint will run on pretty much any PC that hasn't turned 10 yet. So, if you have a computer collecting dust in the closet that you want to get some use from, go for it.

  • How to create an SNS Topic and a Subscriber on AWS

    Amazon Simple Notification Service (SNS) is a web service that coordinates and manages the delivery of messages. It is a highly available, durable, secure, fully managed pub/sub messaging service. It uses cross availability zone message storage to provide high message durability. Amazon SNS also ensures that data is encrypted in transit. It is used to broadcast the messages of a message-producer system.

    To receive messages published to an SNS topic, we must subscribe to an endpoint. We can have endpoints such as AWS Lambda, Amazon SQS, HTTP/S, or an email address to the topic we create. When we subscribe to an endpoint to a topic and confirm the subscription, the endpoint begins to receive messages published to the associated topic.

  • How to configure a Nessus Vulnerability Scan Policy

    Vulnerabilities arise every day with the security specialist engaged in fixing it and the hackers working to exploit it.

There are many tools available in the market for vulnerability scanning. Nessus is one such powerful scanning tool for discovering vulnerabilities. It is developed and maintained by Tenable Network Security Inc. It was once ranked first in the security tools checklist of Nmap Software LLC. Although it is now dropped to the third position in the list, it is still a powerful remote security scanning tool.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. 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 the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • 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.
