Forwarding, firewall rules and at least 2 network interface cards is the minimal requiremnt for setting up router. Our router setup will be on Rhel 8.

• find mostly doesn't need xargs today on modern Unixes

  For usage with find, all of this is unnecessary on a modern Unix and has been for some time, because find folded this into itself. Modern versions of find don't have just the traditional '-exec', which runs one command per file, but also an augmented version of it which aggregates the arguments together like xargs does. This augmented version is used by ending the '-exec' with '+' instead of ';', like so: [...]

• Linux fmt Command – Formatting Text on the Command Line

  The fmt command is a text utility included in the GNU Core Utilities. It was originally created to format email messages at the command line. However, it can be very useful for reading any text files in the terminal. Sure, modern terminals will wrap text to fit in the window. But they don’t wrap at a word, it could split a word right down the middle. This makes it hard to read and even harder to keep your place.

• How To Install Observium on Ubuntu 20.04 LTS - idroot

  In this tutorial, we will show you how to install Observium on Ubuntu 20.04 LTS. For those of you who didn’t know, Observium is a Network Management and Monitoring System that collects data from multiple devices using SNMP and allows you to monitor all of the network’s devices via an easy-to-use interface. It is PHP-based and uses a MySQL database to store data. 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 through the step by step installation of Observium on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian based distribution like Linux Mint.

Contributing to KDE is easier than you think – Bug triaging

Today, 2021-01-28, is the Plasma Beta Review Day for Plasma 5.21, that is to say, Plasma 5.20.90. Right now it’s a bit after 2 a.m., so after this I’m going to bed so I can be present later. This month I’ve mostly been enjoying my post-job vacation as last year I was bordering burnout. As such I didn’t help much. Before bed I’ll be providing a few things I’ve learned about triaging, though. While this blog post isn’t specifically about the Beta Review Day, this should make the general bug triaging process clearer for you, making it quite timely.

• FLOSS Weekly 614: Ethics and Open Source - Openbase, Elastic vs AWS

  Matt Asay believes we need a new way to think about open source. This comes on the heels of the Elastic vs AWS controversy. Shawn Powers and new co-host Katherine Druckman join Doc Searls in a lively discussion of ethics and open source on FLOSS Weekly. The panel takes a look at three efforts currently making news: the Ethical Source Movement; Matt Asay's Infoworld post titled A New Way To Think About Open Source; and Openbase, which Venturebeat says "wants to be the Yelp for open source software packages."

Quick Look at Redcore Linux 2101 Beta

Every once in a while I try Gentoo Linux or something based on it. Redcore Linux is one of those few distributions that made it their mission to "bring the power of Gentoo Linux to the masses". To achieve this it provides a repository of pre-built binary packages on a system that updates on a rolling basis. "Redcore Linux is built from Gentoo Linux stage3. We then add a kernel, a bootloader and a few other things like dbus and initramfs generator (Dracut), we configure the init system (OpenRC) and so we have the core of Redcore Linux, a Gentoo Linux stage4 if you will." A beta build of Redcore 2101 was released only a few days ago that the team apparently feel so confident about that they even think it may be better than some of their earlier stable releases. Given the nature of this distribution one can be sure this is fairly up to date. Redcore beta is using Linux 5.10.5, GCC 10.2.0, Glibc 2.32, binutils 2.35, LLVM 11.0.1, mesa 20.3.2, libdrm 2.4.103, xorg-server 1.20.10, qt 5.15.2, kde-frameworks 5.77, kde-apps 20.12.1, kde-plasma 5.20.5 and flatpak support. The init in use is OpenRC. Redcore provides what's called a hardened Linux system to reduce the available attack surface of the OS. The file Redcore.Linux.Hardened.2101.KDE.amd64.BETA.iso is 3.7 GB in size to download. Despite being hardened the system is supposed to work and targets "casual Laptop/Desktop users and, to some extent, Workstation power users".
