    AsusWrt-Merlin has made available its new 384.14 Beta 3 firmware version compatible with some of ASUS’ routers which merges with GPL 384_81351 and adds “split” busybox applet and IPv6 support to Network Analysis WebUI.

  • What You Probably Didn’t Know About Sudo

    I hope this article proved to you that sudo is a lot more than just a simple prefix. There are tons of possibilities to fine-tune permissions on your system. You cannot just fine-tune permissions, but also improve security by checking digests. Session recordings enable you to check what is happening on your systems. You can also extend the functionality of sudo using plugins, either using something already available or writing your own. Finally, given the list of upcoming features you can see that even if sudo is decades old, it is a living project that is constantly evolving.

  • pf-badhost

    It's been just over a year since version 0.1 of pf-badhost was released. pf-badhost has been downloaded thousands of times. The BSD Now guys even did a spot on pf-badhost. Considering the attention pf-badhost has received, I figured it deserved some love.

    Version 0.2 is a complete rewrite of the script. I've written a basic address parser to allow for proper address verification and error checking. As an added benefit of the new address parsing function, IPv6 lists are now supported as well as mixed lists containting any combination of IPv4, IPv6 and/or CIDR notation.

    The parser also supports arbitrary input formatting for address lists. This means it can be fed addresses in HTML, XML, JSON, CSV etc and be able to parse it into a format suitable for feeding into pf.

  • 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.
