Red Hat and CentOS Fix Kernel Bug in Latest OS Versions, Urge Users to Update

Filed under

Red Hat
Security

It would appear the there was a bug in the previous Linux kernel update for the Red Hat Enterprise Linux 7.5 and CentOS Linux 7.5 releases, which was released to address the Spectre V4 security vulnerability, making connection tracking information to not function correctly, which could lead to connectivity loss and leaking of configuration properties related to the respective connection tracking into other namespaces.

"Previously, the connection tracking information was not cleared properly for packets forwarded to another network namespace," said Red Hat in an advisory. "Packets that were marked with the "NOTRACK" target in one namespace were excluded from connection tracking even in the new namespace. Consequently, a loss of connectivity occasionally occurred, depending on the packet filtering ruleset of the other network namespaces."

How to enable developer mode on a Chrome OS tablet (and install Linux using Crouton)

HowTos

Google’s Chrome OS is designed to be a relatively secure, simple operating system that’s easy to use and hard to mess up. But you can run stable channel, beta channel, or dev channel software on any Chromebook depending on whether you want the safest experience or buggy, bleeding-edge features.

There’s also an option called Developer Mode, which is different from the dev channel. It allows you to access files and settings that are normally protected and use a command shell to explore the system. It’s designed for developers and advanced users only, since it increases the chances that you’ll break your Chromebook. But enabling Developer Mode is also a prerequisite for using one my favorite Chrome OS hacks: a tool called Crouton that allows you to install Ubuntu or another GNU/Linux distribution and run it alongside Chrome OS.

Developers from the SmartOS project announced the release of build #20180705, which promises to help spread Solaris-based software on the headless server market. Most of the media attention regarding free and open-source operating systems these days focuses primarily on implementations of GNU/Linux and *BSD.

illumos, a fork of OpenSolaris, is set to take the world by storm however. It’s perhaps best known for the unusual lack of capitalization in its name, but developers are now really promoting it as a stable Unix system for extremely secure environments.

Test 100+ Linux And Unix Operating Systems Online For Free

Filed under
OS

A while ago, we have covered about OSBoxes, a website that offers a collection of free, ready-to-use Linux and Unix VMs. You can download and try them on your Linux system using VirtualBox or VMWare workstation. Today, I stumbled upon a similar service named “DistroTest”. Unlike OSBoxes, DistroTest allows you to try the live Linux and Unix operating systems for free. You can test 100+ Linux and Unix operating systems online without having to install them locally. Just visit the website, choose the Linux/Unix distro of your choice and fire it up!

Two good Samaritans named Andy Klemann and Tobias Forster have hosted this web service using Debian using Qemu. There is no restrictions to use the public distros listed here. You can use all functions of the system as the way you do in your local system. You can install and uninstall software. You can test installed programs and
even delete or format the hard disk or system files. In a nutshell, DistoTest lets the distro hoppers to decide,

First impressions of PureOS

GNOME

Because it's GNOME, the desktop was immediately familiar to me. I've been a GNOME user for a long time, and I work with GNOME in testing usability of new features. So the GNOME desktop was a definite plus for me.

It's not a stock GNOME, however. PureOS uses a custom theme that doesn't use the same colors as a stock GNOME. GNOME doesn't use color very often, but I noticed this right away in the file manager. Clicking on a navigation item highlights it in a sort of rust color, instead of the usual blue.

Plasma 5.14 Wallpaper “Cluster”

The time for a new Plasma wallpaper is here, so for 5.14 I’m excited to offer up “Cluster”. But first, please allow me to gush for a moment. In tandem with Inkscape, this is the first wallpaper for KDE produced using the ever excellent Krita. For graphic design my computer has a bit of beef to it, but when I work with Inkscape or GIMP things always chug just a bit more than I feel they should. Whenever I’ve had the distinct pleasure of opening Krita, even on my lesser powered laptop, it’s always been productive, rewarding, and performant. I’m looking forward to using Krita more in future wallpapers. *claps for Krita* Read more
