  • Internet routing can now vary based on things you wouldn't expect

    For myself, my lesson learned from this is that if I'm trying to check out the network path to some outside place, I should use 'traceroute -T -p 443' (or the applicable port, but HTTPS is the most likely). Once HTTP/3 becomes common, I'll potentially also want to check with UDP port 443 (although that gets complicated fast). Plain ping and traceroute are not as trustworthy as they used to be any more.

  • How To Install GNS3 on Ubuntu 20.04 LTS - idroot

    In this tutorial, we will show you how to install GNS3 on Ubuntu 20.04 LTS. For those of you who didn’t know, GNS3 (Graphical Network Simulator-3) is an open-source, free Network software emulator that is used by thousands of network professionals to emulate, design, build, configure, test, and troubleshoot the virtual and real complex networks.

    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 GNS3 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.

  • How to use range and sequence expression in bash

    When you are writing a bash script, there are situations where you need to generate a sequence of numbers or strings. One common use of such sequence data is for loop iteration. When you iterate over a range of numbers, the range may be defined in many different ways (e.g., [0, 1, 2,..., 99, 100], [50, 55, 60,..., 75, 80], [10, 9, 8,..., 1, 0], etc). Loop iteration may not be just over a range of numbers. You may need to iterate over a sequence of strings with particular patterns (e.g., incrementing filenames; img001.jpg, img002.jpg, img003.jpg). For this type of loop control, you need to be able to generate a sequence of numbers and/or strings flexibly.

    While you can use a dedicated tool like seq to generate a range of numbers, it is really not necessary to add such external dependency in your bash script when bash itself provides a powerful built-in range function called brace expansion. In this tutorial, let's find out how to generate a sequence of data in bash using brace exapansion and what are useful brace expansion examples.

  • How to Verify a Server for TLS Support on Linux

    TLS is an acronym for Transport Layer Security. TLS facilitates secure communication between computers on the Internet. As of this writing, TLS 1.3 is the latest version. This tutorial explains how you can check which versions of TLS your server or website supports from a Linux system, as well as the encryption algorithm (Cipher) that is being used.

  • How to Play DVDs on Fedora Linux [Quick Tip] - It's FOSS

    Why do you see this error? Because the manufacturers of DVDs encrypt their disks using a Digital Rights Management system named Content Scramble System.

    You can get around it by installing the required software library. Videolan, creators of the VLC player, introduced a project named libdvdcss to get around this issue. According to its page, libdvdcss is a “simple library designed for accessing DVDs like a block device without having to bother about the decryption”.

    As an individual, you may use this software library and no company or FBI should be coming after you as an individual but Fedora or other distribution would avoid including it by default to avoid possible legal troubles at an organization level.

    Due to this legal reason, this library is not available in the Fedora repos. However, it is available on RPMFusion. You can only install it via the command line, but the instructions are simple.

  • 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.
