  • Managing deb Content in Foreman

    Foreman is a data center automation tool to deploy, configure, and patch hosts. It relies on Katello for content management, which in turn relies on Pulp to manage repositories. See Manage content using Pulp Debian for more information.

    Pulp offers many plugins for different content types, including RPM packages, Ansible roles and collections, PyPI packages, and deb content. The latter is called the pulp_deb plugin.

  • Setting the wireless regulatory domain

    Different regions around the world use slightly different frequencies for the various wireless interfaces available on your average Linux portable device such as WiFi, Bluetooth and other such interfaces. Overall they fit into larger categories such as 2.4Ghz, 5Ghz etc, but within each of these larger buckets countries have a subset of the frequencies, generally referred to as channels available. For example the 2.4Ghz range used by most WiFi and Bluetooth interfaces has potentially up to 14 channels available, the default is a generic “world” region which uses 11 channels that are available in all regions, but a lot of regions have 13 available for use, and some even have 14. The situation is similar on the 5Ghz range, and no doubt on the higher frequencies now becoming available too.

  • Securing my IRC (irssi, screen) session with dtach and systemd - anarcat

    A recent vulnerability in GNU screen caused some people to reconsider their commitment to the venerable terminal multiplexing program. GNU screen is probably used by thousands of old sysadmins around the world to run long-standing processes and, particularly, IRC sessions, which are especially vulnerable to arbitrary garbage coming on ... screen, so to speak.

    So this vulnerability matters, and you should definitely pay attention to it. If you haven't switched to tmux yet, now might be a good time to get your fingers trained. But don't switch to it just yet for your IRC session, and read on for a better, more secure solution.

    After all, it's not because we found this flaw in screen that it doesn't exist in tmux (or your favorite terminal emulator, for that matter, a much scarier thought).

  • Tips on managing IoT devices at the edge with Red Hat Ansible Automation

    Internet of Things (IoT) devices are great. They can be deployed out in the field attached to a building or a truck and send back all this amazing data. If things go really well you might have hundreds no thousands of devices deployed.

    Great, we have thousands of devices deployed but how do we manage them? How do we configure and update them without having to send someone out and touch the device? Using Red Hat Ansible Automation Platform and Red Hat Ansible Tower we can centrally manage these remotely deployed devices.

  • 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.

  • 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.
