  • Wi-Fi not working? It's time to consult the lovely people on those fine Linux forums

    Welcome to another edition of Who, Me? in which a Register reader makes the impossible possible and actually gets Wi-Fi working on Linux.

    To be fair to the Penguinistas choking on their mince pies, our tale is set more than 10 years ago, when making Wi-Fi work under Windows could be challenging, let alone on everyone's favourite open-source OS.

    Our story comes from a reader we'll call "Erik" (for that was not his name) who was trying to pop a new version of Linux on his laptop. He was a big SUSE fan but distro-curious, also tinkering with Ubuntu at the time. Alas, exactly which distribution and version is lost to time, so for the purposes of this story we'll go with "Linux."

    The install went well, but all the bells and whistles of Erik's laptop did not seem to be supported. Most importantly, the Wi-Fi. Naturally, he hit the forums in search of help.

  • Fresh liveslak ISO images, setup2hd can now install a basic firewall

    New ISO’s for Slackware Live Edition (based on liveslak-1.5.1) are available for download. You’ll find SLACKWARE (32bit/64bit), XFCE (32bit/64bit), DAW, LEAN, CINNAMON and MATE updated images (see below for download locations). I also refreshed the ‘bonus’ section with nvidia and broadcom-sta drivers matching the installed kernel, and other useful stuff.
    All 32bit ISOs will boot a SMP kernel from now on, since the non-SMP kernels still refuse to execute the init script in the initramfs.

  • 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.
