  • 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.

  7. How to Install Rudder System Configuration and Auditing Tool on Ubuntu 20.04 – VITUX

    Rudder is an open-source and user-friendly web-based system configuration and audit tool. It helps you to manage your IT infrastructure by automating system configurations while ensuring visibility and control of your infrastructure. Two main components of Rudder are: Root server and node. Root server defines the configurations for the systems it manages. The systems managed by Rudder are known as nodes. Rudder manages the nodes using the Rudder agent which is installed on these systems. In today’s post, we will install the Rudder root server and agent on Ubuntu 20.04 LTS. We will use two Ubuntu machines: one as the Rudder root server and the other one as the Rudder node. Note: You must be a root user or have sudo privileges on both machines in order to install the Rudder server and agent.

  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.

LXer: Laptop Dual Boot Project Part 2

I know some of you are wondering why go through all of this when I could just install a Linux distro along side of windows and be done with it? One reason was I had to pay it off. A financed $550 laptop takes a little while to pay off. I didn't want to change the machine any while I owed money on it. And the idea of messing with a bone stock laptop using Linux sounded fun. The good thing now is that I have paid it off so it's all mine to do whatever I want with. So, for me it came down to PCLOS, Mint, SUSE or Ubuntu to install to my laptop. I tried them all 'live' from USB drives and a couple of them using VirtualBox. They are all good distros and there are many articles on why one or the other is good or better for you but for me, it came down to PCLinuxOS or Mint. Having come from Windows originally I am most comfortable with a "Windows like" environment. I think both PCLOS and Mint are two versions of that I like best. I like Mint mire but what has drawn me to PCLOS is that it is the only Linux I have tried in that the backlight on my keyboard works. It may sound dumb but it makes it easier for me being able to see the keys no matter the lighting situation I'm in. I tried to install PCLinuxOS onto my laptop and I got a "can't call method on first_usable_sector unblessed reference" error at the very beginning of the install process. I couldn't get around it and aborted the install. Time to do some research. Come to find out I have a AHCI-RAID problem. I got into the BIOS and changed the SATA configuration from RAID to AHCI but in rebooting, it wouldn't boot. So I went back into my BIOS and wrote down the configuration in the SATA settings. It says I am running the "Intel RST Premium with Intel Optane System Acceleration". I have been looking that up but haven't found much...much I understand that is. More Googling is required. I got back into the boot menu and changed the SATA config back to Intel's RAID setting and it re-booted just fine. It seems that for the moment I am able to run Linux from USB 'live' and under VirtualBox but I am unable to install it to the HD. For those who don't know the big difference AHCI and Raid , it is how they store the data to the hard drive. I'll use a sink with water filling it for the metaphor. RAID 1 offers redundancy through mirroring, i.e., data is written identically to two drives. Think of two sinks with the same water in them. RAID 0 offers no redundancy and instead uses striping, i.e., data is split across all the drives. think of two sinks with the water split between them. Half of the data goes into one drive and the other half into another drive. This means RAID 0 offers no fault tolerance; if the drives fails, the RAID unit fails. Read more
