  • Russell Coker: Dell BIOS Updates

    I have just updated the BIOS on a Dell PowerEdge T110 II. The process isn’t too difficult, Google for the machine name and BIOS, download a shell script encoded firmware image and GPG signature, then run the script on the system in question.

    One problem is that the Dell GPG key isn’t signed by anyone. How hard would it be to get a few well connected people in the Linux community to sign the key used for signing Linux scripts for updating the BIOS? I would be surprised if Dell doesn’t employ a few people who are well connected in the Linux community, they should just ask all employees to sign such GPG keys! Failing that there are plenty of other options. I’d be happy to sign the Dell key if contacted by someone who can prove that they are a responsible person in Dell. If I could phone Dell corporate and ask for the engineering department and then have someone tell me the GPG fingerprint I’ll sign the key and that problem will be partially solved (my key is well connected but you need more than one signature).

  • An inside look at CVE-2020-10713, a.k.a. the GRUB2 "BootHole"

    As GRUB2 upstream maintainers, Oracle developers took the lead on both the disclosure coordination and the technical solutions. In their role as community maintainers for GRUB2, Daniel and Alexsandr were notified of the security vulnerability and immediately began analyzing the impact of these vulnerabilities, coordinating the cross-vendor industry response, and ensuring that this vulnerability would be fixed swiftly. In the end, this coordination effort would entail around 100 individuals from 18 companies.

  • 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.
