  • The OpenSSH server has limits on what user authentication you can use

    We've recently deployed multi-factor authentication for SSH access to some especially sensitive machines, which has caused me to become much more familiar with how OpenSSH's sshd and MFA interact with each other and the limits on that. Unfortunately these limits mean that some combinations of authentication methods are not really available (or not available at all). For example, in many situations you can't require people to use their Unix password and then either a public key or MFA authentication.

  • Things Learned Blogging

    It might seem like an obvious point but if you want to blog, blog. Don’t work on the technology that powers your blog. Work on the content of your blog. A blog is content first, technology only incidentally.

  • Forget Windows, Linux or MacOS: Our choice of the best alternative operating systems

    Built from the ground up but designed to be backward-compatible with its classic quarry, Haiku follows BeOS' lead in its entirely modular design, allowing different components of the OS to be developed concurrently. It’s been a while since the OS had a stable release. In fact, even the second beta release of its under-development branch was released almost two years after the previous one.

  • Filecoin Foundation Ensuring That SecureDrop Can Continue To Help Whistleblowers And Journalists

    Earlier this year we were excited to see the Filecoin Foundation give the Internet Archive its largest donation ever, to help make sure that the Internet Archive is both more sustainable as an organization, and that the works it makes available will be more permanently available on a more distributed, decentralized system. The Internet Archive is a perfect example of the type of organization that can benefit from a more distributed internet.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • 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.
