  • How to generate and backup a gpg keypair on Linux

    Gnu Privacy Guard (gpg) is the Gnu project free and open source implementation of the OpenGPG standard. The gpg encryption system is called “asymmetric” and it is based on public key encryption: we encrypt a document with the public key of a recipient which will be the only one able to decrypt it, since it owns the private key associated with it. Gpg allows us also to sign documents using our private key and let others verify such signature with our public key. In this tutorial we will see how to generate and create a backup of a gpg keypair.

  • How to run a NYM mixnode · Pablo Iranzo Gómez's blog

    Some time ago I’ve started running a NYM mixnode. NYM is a project that targets improving privacy by decomposing network packages from different hosts, so that origin and target cannot be traced.

  • How to run a NYM Validator · Pablo Iranzo Gómez's blog

    As said in the article about mixnodes, NYM is a technology aiming for providing privacy for the communications.

    Apart of the mixnodes, other key piece in the infrastructure are the validators.

    As said, the project uses Open Source technology to run, and they have a nice docs with details on how to run a node at https://nymtech.net/docs/, and the one relevant for mixnodes at https://nymtech.net/docs/run-nym-nodes/validators/.

    In this case, we can follow the instructions for compiling, but I faced some issues (compiling went fine, but initial sync failed), so in this case, we will use the pre-compiled version provided with the 0.10.0 release.

  • How to cast video from Android to Linux | FOSS Linux

    There are many apps and tools out there that will help you cast your Android screen to your Linux PC. However, the main problem is that it only mirrors what’s on the screen and not the audio. This can be an issue if you are trying to cast video from Android, which requires you to forward both video and audio.

    Also, the tools that do let you effectively cast video (including its audio) from your Android device to your Linux PC either require a rooted Android phone or suffers from latency issues. And if not that, then it’s a premium tool and requires you to pay money.

    But it’s Linux we are talking about! Ain’t there a free and open-source tool that will help us cast video and forward audio from Android to Linux?

  • 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.
