  • Certificate Auto Enrollment from Samba – David Mulder

    Certificate Auto Enrollment allows devices to enroll for certificates from Active Directory Certificate Services. As of Samba 4.16, Linux clients can now auto enroll for certificates just like a Windows client.

    Samba’s Certificate Auto Enrollment uses the certmonger service to keep track of certificates. It also uses the cepces plugin to certmonger. The sscep command is also used to download the trust chain.

  • 5 Crontab Examples to Help You Automate Linux Tasks

    The cron program automates the execution of other programs on Linux. Cron is a daemon that runs continuously and starts other programs according to a given schedule. Several different files define this schedule. They are individually known as crontabs.

    Cron can schedule any Unix command or task. Sometimes, you’ll want to work with a simple command. Other times, you’ll need to write a script to carry out the full task. Cron works fine with either approach. It also supports complicated scheduling rules and flexible ways of dealing with the script output.

    Whether you’re carrying out simple user tasks or full-blown system administration, understanding how cron works using practical examples is a must.

  • TLS Email Encryption Explained - How To Encrypt Email with TLS.

    It is no secret that email is the preferred method of communication for businesses - a trend that has only been magnified with the increase in remote workers brought on by the pandemic. That being said, email is effectively a plaintext communication sent from email clients to receiving email servers or from one server to another, leaving the content of messages in transit vulnerable to compromise without additional protection via encryption technology such as the Transport Layer Security (TLS) standard.

    Learn how TLS works to help secure email communications, and how to securely implement TLS in the Postfix mail transfer agent (MTA), Microsoft 365 Exchange Online and Google Workspace to help fortify email against spoofing and data theft.

  • 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.
