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.

Really good to see this. SteamOS had a small update recently, which is testing the waters towards a bigger update.

If you've been wondering why SteamOS updates had been so quiet, it seems Valve has been working on updating their build infrastructure. They have another updating coming, to finally update the graphics drivers and kernel versions which will also be great to have.

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.

Public money, public code? FSFE spearheads open-source initiative

Last September, the non-profit Free Software Foundation Europe (FSFE) launched a new campaign that calls for EU-wide legislation that requires publicly financed software developed for the public sector to be made publicly available under a free and open-source software license. According to the ‘Public Money, Public Code’ open letter, free and open-source software in the public sector would enable anyone to “use, study, share, and improve applications used on a daily basis”. The initiative, says the non-profit, would provide safeguards against public sector organizations being locked into services from specific companies that use “restrictive licenses” to hinder competition. The FSFE also says the open-source model would help improve security in the public sector, as it would allow backdoors and other vulnerabilities to fixed quickly, without depending on one single service provider. Since its launch, the Public Money, Public Code initiative has gained the support of 150 organizations, including WordPress Foundation, Wikimedia Foundation, and Tor, along with nearly 18,000 individuals. With the initiative now approaching its first anniversary, The Daily Swig caught up with FSFE spokesperson Paul Brown, who discussed the campaign’s progress. Read more

Ubuntu: Server Installer, IoT Security, Snaps, Xubuntu

  • The improved 18.04.1 LTS Server Installer - Call for testing!
    With the release of 18.04 LTS Bionic Beaver the new server installer was introduced. At the time, it still lacked certain critical features which have now been implemented.
  • Ubuntu 18.04.1 LTS Introducing Revised Server Installer, Adds Missing Features
    With the April release of Ubuntu 18.04 LTS on the server front was a brand new, in-house developed server installer created by Canonical to differentiate it from Debian's long-used text installer for the Ubuntu Server images. While it offered a fresh look and some new features, it shipped without many features common to Linux server installers. Fortunately, that is changing with the upcoming Ubuntu Server 18.04.1 release. As expected, Canonical is filling in the gaps with their new server installer dubbed Subiquity. With the upcoming Ubuntu 18.04.1 LTS release they will be shipping a new version of this installer. This updated installer now supports LVM, RAID, VLAN, and bonds -- important features missing originally from Ubuntu Server 18.04.0. The functionality is now in place with the latest daily images although the text-based user-interface is still being refined.
  • IoT Security at Scale: Managing end-to-end security
  • Perfectly Formed Snaps Challenge
    Snaps are perfect for the smaller things in life too. Looking away from the graphical flagship apps, the snap store hosts lightweight server daemons, command line utilities, developer tools and even tiny games. Recently, a couple of petite snaps were published in the store. Sparky is a simple game played in a terminal, and a modest 32KB on disk. Bash-Shell-RPG is similarly diminutive at only 8KB. Neither contain an excess of additional libraries, just the absolute minimum needed to function everywhere.
  • What’s New in Xubuntu 18.04 LTS
    Xubuntu 18.04 LTS is the latest release of Xubuntu, it now available to download and install on your laptop and PC. This release features latest version of Xfce 4.12 as default desktop, include latest Xfce components. Xubuntu 18.04 LTS also comes with an updated Greybird GTK+ theme that includes a new dark style, better HiDPI support, greater consistency between GTK+ 2 and GTK+ 3 apps, GTK+ 3 styles for Google Chrome and Chromium web browsers, smaller switches, and improved scales. However, the GTK Theme Configuration tool was removed and it’s no longer possible to override colors in themes.

  • 3 Emacs modes for taking notes
    No matter what line of work you're in, it's inevitable you have to take a few notes. Often, more than a few. If you're like many people in this day and age, you take your notes digitally. Open source enthusiasts have a variety of options for jotting down their ideas, thoughts, and research in electronic format. You might use a web-based tool. You might go for a desktop application. Or, you might turn to the command line. If you use Emacs, that wonderful operating system disguised as a text editor, there are modes that can help you take notes more efficiently. Let's look at three of them.
