  • Too big to care: About the deteriorated abuse handling at some western IT giants

    Imagine you are in need of an ISP to host your 100,000 malware distribution sites. Which one would be your first choice? You operate a website for exchanging stolen credit card data, and need a reliable place for web and DNS services. Where do you go? A botnet operation of yours relies on reachable C&C servers, but even the dirtiest ISPs shut them down quickly. What to do?

    Among the western cloud providers that fit the bill are Google, Microsoft and Cloudflare. Choose three.

    [...]

    Firewall rules tend to fail when it comes to malicious activity originating from big cloud providers or other heavily centralised IT players, such as major ESPs (email service providers). While processing Autonomous Systems makes it easier to permit access to one distinct cloud provider, but drop traffic to others located in the same area, they cannot protect against abuse within the AS or IP networks allowed.

    This is precisely why the author is so disappointed about Google, Microsoft and Cloudflare: Blocking them is impossible in almost any circumstances - even dropping traffic to single IP addresses of them already causes huge collateral damage. Worse, they know they can get away with this attitude. Among the motivations behind this post is to raise pressure on such ISPs, striving for a internet being less dirty than the one we have to make do with today.

    Using IPFire's web proxy in combination with some good and reliable domain-based blocklists2 is not a silver bullet either: While it helps to deny access to knowingly malicious domains hosted on legitimate infrastructure, it is of no use if the offending domain is something like firebasestorage.googleapis[.]com, being abused for hosting phishing sites for years.

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.
