  • A major vulnerability in Sudo

    A longstanding hole in the Sudo privilege-delegation tool that was discovered in late January is a potent local vulnerability. Exploiting it allows local users to run code of their choosing as root by way of a bog-standard heap-buffer overflow. It seems like the kind of bug that might have been found earlier via code inspection or fuzzing, but it has remained in this security-sensitive utility since it was introduced in 2011.

    Qualys reported the bug on January 26; it has been in Sudo from version 1.8.2, released in August 2011, up through 1.9.5p1, which was released on January 11. At the same time as the announcement, Sudo released version 1.9.5p2 to fix the problems. The bug has been assigned CVE-2021-3156, which Qualys has dubbed "Baron Samedit". That name combines Baron Samedi, the name of the vodou loa of the dead, with sudoedit, which is integral to the exploit.

  • [Older] Best Linux distro for developers

    Linux inherently works well for coding and testing software. For developers and programmers, almost any Linux distro will be a good fit. When it comes to picking a distro for developing, the biggest factor is just going to be personal preference. Even so, some distros offer certain features that developers may find particularly helpful for their work.

    With so many choices available, the task of choosing a distribution can be overwhelming. At the same time, jumping ship to "distro hop" is very easy to do, and shouldn't be discouraged, as it gives you an idea of what else is available. We aim to make your choice a little easier with this guide, where we list our top picks of Linux distros for developers.

    Join us as we go over our top eight picks of Linux distros, presented in no particular order. Outside of this list, there are still many other good distros that you can try. And it's important to remember that there is no wrong choice. Let the countdown begin.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • 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.
