5 Best Free and Open Source Linux MAC/RBAC Tools

Software
OSS

One of the most difficult problems in managing a large network is the complexity of security administration. The deployment of individual security products such as firewalls, intrusion detection systems, network traffic analysis, log file analysis, or antivirus software is never going to provide adequate protection for computers that are connected to the internet. For example, a good network intrusion prevention and detection system (such as Snort) does an exemplary job at detecting attacks within traffic. However, this type of detection does not offer any sort of damage containment. Equally, a firewall offers an outstanding method at defining what type of traffic is allowed in a network, but does not offer any deep protocol analysis.

10 Best Free and Open Source Linux Educational Games

Filed under
OSS
Gaming

Educational games are games designed to teach people, typically children, about a certain subject or help them learn a skill as they play. Sometimes this type of software is known as games edutainment because they combine education and entertainment.

This type of software aids the ‘normal’ learning process, either by helping the individual to absorb new information, or as a support for recalling information already learned. Educational programs, especially those for the youngest students, are often designed with the idea of ‘learn through play’. Many children are easily bored, and they are much more likely to be attentive if they find the activity or task to be enjoyable.

Best Free and Open Source Alternatives to Adobe XD

Filed under
Software
OSS

We are long-standing admirers of Adobe’s products. They develop many high quality proprietary programs. It’s true there are security and privacy concerns in relation to some of their products. And there’s considerable criticism attached to their pricing practices. But the real issue is Adobe Creative Cloud does not support Linux. And there’s no prospect of support forthcoming.

What if you are looking to move away from Adobe and embark on a new world of online freedom, where you are not tracked, monetised and attached to Adobe’s ecosystem. We only recommend free and open source alternatives. Our recommended software don’t necessarily replicate every feature of their Adobe counterparts but they offer sufficient functionality for many tasks.

5 open source alternatives to Microsoft Exchange

Filed under
OSS

For decades, Microsoft Exchange has ruled the market for email and groupware services. This top dog dominates the corporate world, and the omnipresent Outlook mail client has become the de facto standard for groupware. Since Exchange is closely integrated with Microsoft's Office products, users have access to a wide variety of productivity software and features, whether they're using a desktop or a mobile client.

However, many companies have concerns about storing their data in the Microsoft cloud. In this article, I look at some open source alternatives and their advantages. It's not just about becoming vendor-independent and reducing costs; it's about using software with open standards and a different level of security—for the groupware server itself and the operating system behind it.

  • Two days at the Open Source Experience - Le blog d'Emmanuel

    I was at the Open Source Experience event in Paris, France last week.

    While it was nice to see friends from the FLOSS community, it did feel that the general public decided to stay away, probably because Covid cases are on the rise in France again. I was manning a Perl booth but used the fact that we were 4 people to wander again and ask vendors if they would be willing to support their applications in Fedora. As you can probably guess, results were mixed...

  • Data centre networking: what is OVS? | Ubuntu

    In one of our preceding blogs, we spoke about Software-Defined Networking (SDN) and the key drivers behind it. Virtualisation is one of the fundamental aspects that characterises SDN, and has influenced the architecture of network switching in the data centre. OVS (Open vSwitch) is a fundamental component of modern and open data centre SDNs, where it aggregates all the virtual machines at the server hypervisor layer. It represents the ingress point for all the traffic exiting VMs, and can be used to forward traffic between multiple virtual network functions in the form of service chains. Let’s take a closer look in order to understand what OVS is.

  1. Collaborate on a file using Linux diff and patch

    I edit a lot of text files. Sometimes it's code. Other times it's the written word for role-playing games (RPGs), programming books, or general correspondence. Sometimes it's nice to make a change, but for my collaborator to compare my change with what they originally had written. Many people default to office suites, like LibreOffice, using comments or change tracking features. Sometimes a simpler tool makes more sense, though, and for that, you can look at programming history for tools like diff and patch, which provide standardized formatting for tracking and applying changes to shared files.

  3. Quickemu- Run Windows 11 on Ubuntu 20.04 LTS Linux in few clicks

    o you want to install Windows 10 or 11 on your Ubuntu 20.04 or 22.04 LTS Linux using QEMU-KVM virtual machine? Then here is a tutorial to do that using the command terminal and Quickemu + Quickgui. Although we all have a simple solution that is a virtual box to run Windows 11 virtual machine, what about KVM? Some will say it is not easy to operate because of the command line but no there are few open-source GUI programs to give KVM an easy interface. However, another thing is downloading ISO images of various operating systems including Windows 10 or 11 to use with Virtualbox can be a headache. Hence, to solve all of this, there is a project called QuickEMU with a GUI interface known as QuickGUI. QickEMU uses QEMU_KVM on Linux operating system to run a virtual machine and can easily download all popular operating system Images to install including macOS. Whereas it can be operated via CLI but for ease of usage users can install QuickGUI to download, create, and manage operating systems virtual machines.

  4. Steinar H. Gunderson: Commitcoin

    How do you get a git commit with an interesting commit ID (or “SHA”)? Of course, interesting is in the eye of the beholder, but let's define it as having many repeated hex nibbles, e.g. “000” in the commit would be somewhat interesting and “8888888888888888888888888” would be very interesting. This is pretty similar to the dreaded cryptocoin mining; we have no simple way of forcing a given SHA-1 hash unless someone manages a complete second-preimage break, so we must brute-force. (And hopefully without boiling the planet in the process; we'd have to settle for a bit shorter runs than in the example above.) Git commit IDs are SHA-1 checksums of what they contain; the tree object (“what does the commit contain”), the parents, the commit message and some dates. Of those, let's use the author date as the nonce (I chose to keep the committer date truthful, so as to not be accused of forging history too much). We can set up a shell script to commit with --amend, sweeping GIT_AUTHOR_DATE over the course of a day or so and having EDITOR=true in order not to have to close the editor all the time.

  8. How to check if packages in RHEL-based Linux distributions have been patched for specific CVEs - TechRepublic

    CVEs (Common Vulnerabilities and Exposures) are constantly being discovered and patched. When discovered, it means a new security flaw exists in either an operating system or a piece of software and should be patched as soon as possible. Fixing the vulnerabilities, of course, is up to the developers. Patching those vulnerabilities, however, is up to the admin (or user). Thing is, you might not know if you're using a piece of software that includes one or more CVEs. How do you uncover this information? Do you have to spend hours researching? Not really. In fact, all you need to know is the CVE you're looking for and the piece of software it affects. With those two bits of information in hand, you can quickly discover if what's installed on your Red Hat Enterprise Linux-based distribution contains that vulnerability. I'm going to show you how to do just that.
