  • Set Up DNS over HTTPS (DoH) Resolver on Debian with DNSdist

    DNS (Domain Name System) is responsible for translating domain names to IP addresses. It’s designed in 1987 with no security or privacy in mind. By default, DNS queries are not encrypted. They are sent in plain text on the wire and can be exploited by middle entities. For example, the Great Firewall (GFW) of China uses a technique called DNS cache poison to censor the Chinese Internet. (They also use other methods, which are beyond the scope of this article.)

  • Geo replication with syncthing

    Some years ago I started using geo replication to keep a copy of all the pictures, docs, etc

    After being using BitTorrent sync and later resilio sync (even if I didn’t fully liked the idea of it being not open source), I gave up. My NAS with 16 GB of ram, even if a bit older (HP N54L), seemed not to have enough memory to run it, and was constantly swapping.

    Checking the list of processes pointed to the rslsync process as the culprit, and apparently the cause is the way it handles the files it controls.

    The problem is that even one file is deleted long ago, rslsync does keep it in the database… and in memory. After checking with their support (as I had a family license), the workaround was to remove the folder and create a new one, which in parallel meant having to configure it again on all the systems that used for keeping a copy.

  • 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.
