  • How to Use Two-Factor Authentication with Ubuntu

    Over time, the traditional username and password authentication has proven inadequate in providing robust security to applications and systems. Usernames and passwords can easily be cracked using a plethora of hacking tools, leaving your system vulnerable to breaches. For this reason, any company or entity that takes security seriously needs to implement 2-Factor authentication.

    Colloquially known as MFA (Multi-Factor Authentication), 2-Factor authentication provides an extra layer of security that requires users to provides certain details such as codes, or OTP (One Time Password) before or after authenticating with the usual username and password.

    Nowadays multiple companies such as Google, Facebook, Twitter, and AWS, to mention a few provide users the choice of setting up MFA to further protect their accounts.

  • How to Run the Same Command Multiple Times in Linux – Linux Hint

    When programming, you may encounter a situation in which you need to perform the same task multiple times. A simple solution is to manually repeat the process as many times as it is needed; however, it is not productive to do so. That is why the concept of loops was introduced to programming. The basic goal of a loop is to repeat a task several times, depending upon the value provided for the iterator and the termination condition of the loop. Loops allow programmers to avoid the hassle of repeating processes manually.
    Suppose that there is a command that you wish to run multiple times. There are several important reasons that you might need to run a command repeatedly, so you want to be sure that a certain command produces the correct output every time it is executed. The more you run a command manually, the more certainty you will gain each time you run the command.

    But how do you do this programmatically? Well, there are several methods that can be used to run the same command multiple times, as well as for verifying the output of the repeated command. This article shows you how to create a repeatable command using Linux Mint 20 as the host operating system.

  • 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.
