  • Firewalld: The Future is nftables

    Firewalld, the default firewall management tool in Red Hat Enterprise Linux and Fedora, has gained long sought support for nftables. This was announced in detail on firewalld’s project blog. The feature landed in the firewalld 0.6.0 release as the new default firewall backend.

  • How SELinux helps mitigate risk while facilitating compliance

    Many of our customers are required to meet a variety of regulatory requirements. Red Hat Enterprise Linux includes security technologies that help meet these requirements. Improving Linux security also benefits our layered products, such as Red Hat OpenShift Container Platform and Red Hat OpenStack Platform.

  • WPA3: How and why the Wi-Fi standard matters

    WPA2 has given us 14 years of secure wireless networking. WPA3 will fix a number of big problems in WPA2 and make strong security the default condition.

  • How one man could have hacked every Mac developer (73% of them, anyway)

    OK, in some ways that’s only very loosely true, when you think of all the non-Unixy stuff on top of the Darwin base layer, and we welcome your comments below to explain just how carelessly loose we have been…

    [...]

    The potential impact of a well-thought-out hack into one of the many package management ecosystems out there is a pet concern of security researcher Eric Holmes.

    Hacks against the very repositories that many of us rely upon for software updates are known in the jargon as supply-chain attacks – after all, the modern supply chain often doesn’t involve any factories, ships, trains, inventories, trucks, pallets or forklifts.

    So, Holmes decided to take a look at the supply chain for Homebrew, or Brew for short – we’re guessing he picked Brew not only because he knew it was the most popular amongst the Mac community, but also because he uses it himself.

    The results were, in a word, salutary.

  • SD Times Open-Source Project of the Week: Fizz

    In order to implement the new generation of Transport Layer Security, TLS 1.3, at Facebook, the company built a TLS library in C++ 14 called Fizz. Earlier this week, Facebook announced it was open sourcing that library.

    TLS 1.3 added several new features to make Internet traffic more secure, such as encrypting handshake methods, redesigning how secret keys are derived, and a zero round-trip connection setup.

    “We are excited to be open-sourcing Fizz to help speed up deployment of TLS 1.3 across the internet and help others make their apps and services faster and more secure,” Facebook wrote in a post.

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.
