  • Intel CET Support Still Getting Squared Away For Linux In 2020

    Various open-source patches have gone back to at least 2017 for enabling Intel's Control-Flow Enforcement Technology (CET) for the Linux kernel and related components. This is the Intel feature for helping prevent ROP and COP/JOP style attacks via indirect branch tracking and a shadow stack. Recently there has been a fair amount of CET improvements to the various open-source components.

    [...]

    That though could hopefully change soon as a few weeks ago the v10 patches for control-flow enforcement with enabling the shadow stack was sent out. Those kernel patches though are still in flux so might not be mainlined even for the upcoming Linux 5.8 kernel.

    Outside of the kernel though, over in GCC space for GCC 11 is now defaulting the CET run-time support to auto for the compiler-side bits. So that's important for seeing CET support available by default on more systems.

  • The 15 Best Hacking Apps for Android Device in 2020

    Sometimes, we are out of an internet connection or our cellular data and need to have a connection badly. Getting connected to others’ connections is the only way to handle such a situation.

There are some apps in Playstore that can help you by providing that info, and we call them the hacking apps for Android.

  • 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.
