    How to test Windows 11 without an upgrade http://linuxbyexample.org/how-to-test-windows-11-without-an-upgrade/ Tue, 23 Nov 2021 20:00:00 +0000 http://linuxbyexample.org/how-to-test-windows-11-without-an-upgrade/

    Microsoft once said that Windows 10 will be the last platform in its line. However, this has not been the case since the Redmond-based company recently released Windows 11. This marked the beginning of a new era for Microsoft’s flagship operating system franchise.

    So now you can install Windows 11 if your PC meets the system requirements. However, some users may not be sure whether or not to upgrade to the latest desktop platform. Prefer to try Windows 11 without upgrading to it? If so, you can do just that as described below.

    Microsoft’s Windows 11 rollout

    Microsoft unleashed Windows 11 on October 5, 2021. The new operating system is now being distributed to compatible Windows 10 devices in a step-by-step rollout process. The software giant is rolling out its latest desktop platform as a free upgrade for customers in 2021 and 2022.

    If your Windows 10 PC meets all the system requirements for the new platform, you will receive a free upgrade offer. This offer appears within the Windows Update Tab in settings. If you accept this offer, you can click on it Download and install click there to update

    MAKEUSEO VIDEO OF THE DAY

    The download and installation option for Windows 11

    So it’s easy enough to upgrade from Windows 10 to Windows 11. However, do you want to upgrade? Sure, you can read reviews for the latest operating system; But the best way to see what the new platform looks like without upgrading is to try it out with virtualization software.

    What is virtualization software?

    Virtualization software packages are those that divide the system resources of PCs into virtual computers. They allow you to use Windows, Mac, Linux and other operating systems within a window without installing them over your PC’s existing platform. An operating system executed within the virtualization software is referred to as a virtual machine.

    Therefore, virtualization software packages provide a way to try out many different platforms on your PC. To give Windows 11 a test run before upgrading, you can install a desktop VM application.

    There are numerous virtualization software packages for Windows 10. Some of them are freely available, such as VMware Workstation 16 player and VirtualBox. So you can try Windows 11 with the VMware Workstation 16 hypervisor at no additional cost.

    Related: How to Use VirtualBox: User Guide

    1. Download VMware Workstation 16 Player and a Windows 11 ISO

    First, you need to download and install VMware Workstation 16 Player. To do this, click on the Download now Link (for the Windows version) on the VMware Workstation 16 Player website. If you haven’t changed your browser’s default settings, it will automatically be downloaded to your Downloads folder.

    The Download Now link

    After downloading the VMware Workstation setup wizard, install the software. Press File Manager window + Button E. Hotkey. Open the folder that contains the VMware Workstation installer. Then double-click the VMware Player EXE file to open the setup wizard and install the application.

    You will also need to download a Windows 11 ISO file. You can download this file from the Windows 11 Download page. Choose first Windows 11 in the Edition dropdown menu there and click on that Download Button. Next, select a product language from the drop-down menu and select the Confirm Opportunity. Then press the 64-bit download Button.

    The download button

    2. Set up a Windows 11 virtual machine with VMware Workstation 16 Player

    After choosing your language settings, you will be taken to a step on how to activate Windows. You do not need to enter a product key for installation. So you can click I don’t have a product key Option to skip it. However, Windows 11 runs with some restrictions while an “Activate Windows” message appears in the lower right corner of the screen. The Settings app will also prompt you to purchase a Windows 11 product key.

    The I don't have a product key option

    Alternatively, you can enter a generic Windows 11 product key there. These are temporary keys that you can enter to install and try out Windows platforms. However, generic keys expire in 30-90 days unless you are in an organization with a key management service.

    These are four generic keys for Windows 11 alternate editions:

    • Windows 11 start page: YTMG3-N6DKC-DKB77-7M9GH-8HVX7
    • Windows 11 Pro: VK7JG-NPHTM-C97JM-9MPGT-3V66T

    Indian bank denies disclosing data on 180 million customers • The Register http://linuxbyexample.org/indian-bank-denies-disclosing-data-on-180-million-customers-the-register/ Tue, 23 Nov 2021 01:58:00 +0000 http://linuxbyexample.org/indian-bank-denies-disclosing-data-on-180-million-customers-the-register/

    India’s Punjab National Bank has denied a security firm’s allegation that it disclosed the personal and financial information of its 180 million customers – but appears to have admitted that their Exchange Server implementation was not in tip-top shape.

    The allegation was made by Indian security consultancy CyberX9, who blogged on Sunday that they had discovered an unpatched vulnerability in the bank’s systems that allows it to access an internal server at the administrator level.

    According to the CyberX9 article, active exploits already in circulation that target the vulnerability could mean that an attacker “had the potential to remotely execute any code, steal data, conduct transactions and have complete control over such connected computer systems to get”.

    Note that “potentially” – because CyberX9’s post does not reveal which system was affected. But in the Indian outlet Money control the company should be able to secure access to an Exchange server. In the same report, the bank admitted to using Exchange, but the allegedly unpatched servers were only used to route emails to Office365 and do not contain any sensitive data.

    In a message pinned to the homepage and the Money control The bank’s report also stated that its core banking systems and customer data are isolated from the infrastructure exposed by the vulnerability.

    “We have thoroughly checked our ICT systems, which are connected to the Internet and run in the background at PNB,” the statement reads, adding: “There was no system breach and no personal data theft of our customers and account holders at PNB . “

    The notice also states that the bank is using data loss prevention tools that “prevent unauthorized data from being sent via email”.

    CyberX9 claims the bank has been exposed for seven months – a timeframe that seems plausible in April 2021. Microsoft has disclosed four serious bugs in Exchange Server. These shortcomings were serious enough that the United States National Security Agency urged them to be resolved quickly, as they could allow “permanent access and control over corporate networks.”

    If the Punjab National Bank does not apply these patches, it has fallen far short of best practice despite its isolation measures.

    CyberX9 has requested a public audit of the bank to put customers at ease.

    The registry has contacted CyberX9 and the bank for a comment and will update this story when we receive meaningful responses. ®

    Microsoft Unveils App Service Auto-Scaling Preview • The Register http://linuxbyexample.org/microsoft-unveils-app-service-auto-scaling-preview-the-register/ Mon, 22 Nov 2021 19:01:00 +0000 http://linuxbyexample.org/microsoft-unveils-app-service-auto-scaling-preview-the-register/

    Microsoft has provided an early preview of Azure App Service Automatic Scaling – a handy tool provided Azure hasn’t reached capacity again.

    The auto-scaling feature is designed to remove all the annoying rules and schedules of the existing Azure versions Auto scaling in favor of something managed by the platform itself.

    When activated via the Azure CLI or ARM template, the feature automatically scales the number of running app instances when the number of requests increases and scales things back down when the demand decreases. Developers can set limits and minimums for the service; The latter is useful for dealing with bottlenecks while the former is essential to avoid a heartbreaking bill.

    Once configured, auto-scaling takes precedence over existing auto-scaling rules and schedules. Microsoft also recommends turning off health checks for web apps that have the feature enabled.

    “The health check requests can cause unnecessary fluctuations in HTTP traffic,” said the company. What a shame Health control is a useful way to see if your app is off schedule.

    One cynic might suggest that Microsoft could use such a tool for its own notoriously shaky endeavors in the cloud.

    The costs are billed to the second and the preview works with existing Premium Pv2 and Pv3 SKUs. It’s also only for the Azure App Service for Windows and Linux, and amazingly, Microsoft has so far resisted the urge to tinker with the Azure Portal user interface; The preview must be configured using the Azure CLI or the ARM template.

    While Autoscale has been around for a long time in the Azure world, defining the metrics and load plans can be tedious, although complete control over how and when to scale will no doubt remain a preference of cautious administrators.

    Microsoft’s cloud rival AWS also offers a variety of scaling options, including the vaguely scary sounding one Predictive scaling, which uses machine learning models to predict a customer’s traffic and resource needs. ®

    Svix, provider of no-code webhooks, snaps $ 2.6 million to simplify software management http://linuxbyexample.org/svix-provider-of-no-code-webhooks-snaps-2-6-million-to-simplify-software-management/ Sun, 21 Nov 2021 17:20:45 +0000 http://linuxbyexample.org/svix-provider-of-no-code-webhooks-snaps-2-6-million-to-simplify-software-management/

    Hear from CIOs, CTOs, and other C-level and senior executives about data and AI strategies at the Future of Work Summit on January 12, 2022. Learn more


    Today, Webhooks as a Service Provider (WaaS) Svix announced a $ 2.6 million pre-seed funding round with Y Combinator and Aleph. The organization claims it will use the funds to expand the development, trade and operations teams.

    The WaaS platform was designed to provide developers with a solution for triggering API notifications instead of having to create their own webhook system.

    “Webhooks are increasingly driving no-code and low-code activity across the web, but sending them still requires a lot of development time, development resources, and ongoing maintenance. Svix is ​​the first platform that solves this problem, ”said Tom Hacohen, CEO of Svix.

    The release of no-code webhooks solutions like Svix enables developers to connect webhooks to applications without having to build the underlying infrastructure. At the same time, this means that decision-makers spend less time and money on setting up and maintaining webhook systems.

    Connect different apps with webhooks

    Research shows that employees switch over 13 apps an average of 30 times a day. Many companies want to consolidate these solutions and make it easier for employees to understand the information they contain.

    The company hopes to meet this challenge by enabling apps to exchange data via an API. “Webhooks have the potential to be the nervous system of every SaaS product and to pass data to every other application in a one-sided and controlled manner,” said Aaron Rosenson, general partner at Aleph.

    “They are some of the most powerful, underrated tools for modern software development, and Svix created the first enterprise-class product to holistically manage them,” he added.

    While webhooks offer a solution to this challenge, traditionally they have had to develop an infrastructure to configure the webhooks. This complexity has led to a move towards low-code or no-code webhooks solutions.

    The low-code / no-code webhooks movement

    A number of solution providers have emerged in recent years to make webhooks more accessible to developers. Other competitors include smaller SaaS providers like HostedHooks and established automation platforms like Zapier, the latter of which reached a valuation of $ 5 billion and sales of $ 140 million last year.

    Zapier is one of Svix’s main competitors and offers a no-code solution for automating and connecting webhooks to applications like Slack, Twitter, Gmail, HubSpot and Salesforce.

    “A great developer experience is the cornerstone of our product; That’s why we have SDKS [software development kits] for many of the most popular programming languages ​​and offer a pre-built app portal that allows your users to manage, test, debug and monitor their webhooks without having to create them, ”said Hacohen.

    Simplify webhooks

    Essentially, Svix provides an application portal for users to add webhook endpoints and manage them from a central location. The portal is intended to make it unnecessary for developers to set up their own infrastructure for configuring webhooks.

    Since its inception, Svix has positioned itself in the market as an easy-to-use WaaS solution and has sought to establish itself by gradually adding new features to improve the user experience.

    Svix recently released a feature to automatically generate documentation for customer webhooks, which Hacohen intends to build on by enabling customers to generate libraries and automatically offer them to their users.

    Distrowatch Top 5 Distributions Review: Pop! _OS http://linuxbyexample.org/distrowatch-top-5-distributions-review-pop-_os/ Sun, 21 Nov 2021 05:15:00 +0000 http://linuxbyexample.org/distrowatch-top-5-distributions-review-pop-_os/

    Pop! _OS ranks fifth fromn the popular ranking site Distrowatch, based on the number of hits on the Distrowatch page for the operating system, not based on actual downloads / user base. You can read my reviews of the other four top spots by following these links: Linux Mint, Manjaro, EndeavorOS, and MX Linux.

    There aren’t many Linux distros that I haven’t tried … but pop! _OS is one of them, and so it’s literally the first time I’ve touched the operating system doing this review … and I liked it and had serious problems with it.

    For those unfamiliar with Pop! _OS, it’s an Ubuntu-based distribution from System76, a popular maker of Linux-centric pre-built computers. The distribution is widely considered to be stable, modern, feature-filled, and beginner-friendly, as well as fairly minimalist in terms of gas.

    There is only one variant of Pop! _OS, GNOME, and the operating system is therefore specially designed for it.

    My specs:

    • Ryzen 5 3500X
    • NVIDIA GTX 1660 Super
    • 16GB DDR4 3000Mhz
    • System installed on a SATA SSD

    installation

    I wish I could say I didn’t have any problems installing it as Pop! _OS would sound so much less daunting at the beginning of this article … however, it didn’t. First, I decided to install Pop! _OS 20.04 LTS, using their special version for NVIDIA GPUs so I wouldn’t have to mess with Nouveau; However, an installation error occurred while trying to install no matter what I did. Googling the problem did not produce any meaningful or helpful results either. I created the Live USB with dd from another Linux system so I knew it wasn’t the tool / utility that was causing the USB error. So I decided to try 04/21 (NVIDIA) instead, even though it’s not the LTS and therefore has less long-term support … And voila! It worked.

    I’ve never seen the installer utility before so I’m assuming that it was specifically designed for Pop! _OS and I have to say that it is very well designed. It was attractive, organized, easy to understand, and offered many opportunities. The installation itself, once I got it going, was painless and very, very quick.

    Included software and features

    Here PopOS is both minimal and fully functional. As for the software that comes with it, there really isn’t much … LibreOffice has been installed, as has Firefox and the Geary email client … but that was pretty much all aside from basic utilities, a dock, and the Pop! _Shop (software installer). Even proprietary multimedia formats such as MP3 and DVD decoders are not included as standard.

    That makes Pop! _OS attractive to those looking for a super minimal system that can be built almost from scratch … but don’t confuse this with a lack of functionality. Pop! _OS comes with full-disk encryption enabled by default which is very rare (their website claims that they are the only Linux distro that does this, but I can’t confirm this), the ability to do an OS update that will quickly and easily reinstall the OS while keeping your home Folder, and that’s pretty much clarifying on their website about their stance on privacy,

    Pop! _OS does not collect or store any information from user installations. Minimal operating system and hardware information is used – not stored – to provide updates and connectivity checks. Apps packaged via Flatpak require permissions to access more than what is required to function. “

    It was also interesting that I didn’t have to enter my root password when installing software like GIMP from the POP! _Shop; something I think I’ve never seen before. I’m not 100% sure what to think of this, but it’s totally worth mentioning.

    Overall, I was impressed by this side of Pop! _OS. I really don’t like GNOME, but this was probably the most organized and designed GNOME system I’ve used.

    power

    Pop! _OS was a little heavier than I expected. With LibreOffice Writer open and Firefox with four tabs open, my CPU had an average utilization of 16% with 2.9 GB of RAM used. I attribute this to the fact that GNOME is not very lightweight; but overall, I have never faced slowdowns, hiccups, slow launching applications, or hanging applications. As long as you are using a semi-modern PC, everything is fine.

    Final thoughts

    Personally, I’m not going to be using Pop! _OS because I loathe GNOME, but I have to admit it’s a really attractive operating system, with some good features under the hood, a minimalist approach in terms of gas, and based on Ubuntu, you can expect lots easy to find support. If all of this sounds good, I highly recommend checking out this distro, you may love it!

    Now you:

    How to install Docker CE on Ubuntu 22.04 LTS Jammy Jellyfish http://linuxbyexample.org/how-to-install-docker-ce-on-ubuntu-22-04-lts-jammy-jellyfish/ Sat, 20 Nov 2021 13:51:15 +0000 http://linuxbyexample.org/how-to-install-docker-ce-on-ubuntu-22-04-lts-jammy-jellyfish/

    Docker is an open source project that gives us the ability to easily run applications in isolated containers. Those who use Ubuntu 22.04 LTS and want to install Docker CE to run containers of various Linux apps can follow this tutorial.

    Another advantage of Docker containers is that they can build on one another and communicate with one another. Examples of these applications are an Apache server or a MySQL database.

    Unlike normal virtual machines, we don’t need every container to run a complete operating system. I mean, if we want to operate a web server that is separate from the database server, we would have to start two complete virtual machines including the operating system. This is not the case with Docker, the underlying kernel will be the same and two independent containers can be started for the respective servers without installing the full-blown operating system; instead, a light Docker image does the work.

    In addition, Docker is a cross-platform project, so the command is executed the same for everyone regardless of the operating system (Windows, Linux or macOS) and there are no compatibility issues between the containers.

    Steps to install Docker CE on Ubuntu 22.04 LTS Jammy Jellyfish

    1. System update and installation of some tools

    sudo apt update
    sudo apt install ca-certificates curl apt-transport-https

    2. Add GPG key

    To download the packages from Docker on Ubuntu we need to add the GPG key that is used to sign the Docker packages by its developer, otherwise the system will return an error and will not be able to use the repository.

    curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

    3. Add the Docker repository on Ubuntu 22.04

    We can install the Docker using the standard Ubuntu Jammy system repository, but the version available won’t be the latest. So, manually add Docker’s official repository using the command block given below.

    Copy the quite Command block in your terminal:

    echo "deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable" 
    | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

    4. Install the Docker engine on Ubuntu 22.04

    Finally, we configured all the necessary things that we needed. Now just run the System Update command to update the repository cache and update packages that have already been installed. After that, use the APT packages to get all the Docker tools we need to create containers.

    sudo apt update
    sudo apt-get install docker-ce docker-ce-cli containerd.io

    Install Docker Engine Ubuntu 22.04 Jammy

    To check if the Docker service is running:

    systemctl status docker

    In case it doesn’t work, use:

    sudo systemctl start docker

    5. Use Docker without sudo

    Once the installation is complete, we need to add our current system user to the Docker group, otherwise every time we ‘sudo‘with every command of the Docker.

    sudo usermod -aG docker $USER
    newgrp docker

    To check the version:

    docker version

    Running the Docker command without sudo

    6. Create container

    Now we can start creating our first container. For example, let’s say you want to create a Debian bullseye container. To do this, we draw its Docker image.

    docker pull debian

    Create container:

    docker create -it --name test debian

    Start container

    docker start test

    Get the command line of the installed container:

    docker attach test

    Create Docker container on Ubuntu 22.04 LTS

    Open source executives are trying to bridge the loopholes in software supply chain security http://linuxbyexample.org/open-source-executives-are-trying-to-bridge-the-loopholes-in-software-supply-chain-security/ Fri, 19 Nov 2021 23:30:38 +0000 http://linuxbyexample.org/open-source-executives-are-trying-to-bridge-the-loopholes-in-software-supply-chain-security/

    The security of the software supply chain has become increasingly important in the past year. Two major cybersecurity attacks – SolarWinds and Kaseya – have emerged as urgent reminders to scrutinize every component of software development and deployment, including where they come from and where they come from.

    The first signs of a major security gap in the supply chain appeared over four years ago when the malware wiper NotPetya was launched against Ukraine in 2017, a Ukrainian company. The result was an estimated $ 10 billion damage affecting businesses in Asia, Europe, and the Americas.

    From a cost perspective, NotPetya was just a drop in the ocean. The cost of responding to incidents to repair damage from the SolarWinds attack is estimated at over $ 100 billion, while additional costs for recovery from the Kaseya attack are still being calculated earlier this year. Bottom line: The cost of security breaches in the software supply chain has grown exponentially, and open source is proving to be the primary target.

    “We’re seeing an increase in attacks,” said Luke Hinds, Head of Security Technology, Office of the CTO, Red Hat Inc., in a recent interview with theCUBE, SiliconANGLE Media’s live streaming studio. “There’s a recent statistic that has come out … a 620% increase since last year in supply chain attacks involving the open source ecosystem. So things are definitely looking up. “

    A complex problem

    The recent incidents prompted the White House to issue an executive order in June aimed at protecting government systems from attacks on the software supply chain. More importantly, concerns about software security have led some of the largest computer companies in the world to find technology solutions that reduce the potential for future exploits.

    Part of the problem is that not all of the software in the world is behind closed gates. According to Red Hat’s The State of Enterprise Open Source report, 90% of IT executives say they will use open source tools for businesses and 79% expect to use open source software in the next two years will increase.

    The challenge of protecting open source software, developed by many contributors, is akin to securing a bank vault where anyone can come and go as they please. What’s inside is extremely valuable, but there are no guards or locks on the vault door.

    “This is a complex problem,” said Sandy Carielli, principal analyst at Forrester Research, in an interview with SiliconANGLE for the story. “Companies want to perform additional controls and analysis on the security of the software supply chain in order to reduce risk. One of the problems is that open source is so ubiquitous. “

    Open source initiatives

    Red Hat Inc. has come up with some ideas to address this challenge and is starting a project called Sigstore, which will automate the digital signature and verification of software elements. The aim is to provide a free tool that verifies the origin of software and enables developers to use open source solutions safely. The bank vault is still wide open, but only verified, trustworthy sources are allowed to touch the inside.

    Sigstore is a project originally prototyped at Red Hat, and the company positioned it as an “open response” to the trust and security of the software supply chain. Red Hat has actively sought support for the industry around the digital signature solution.

    “We have big plans with Sigstore, and that’s where the partnership comes in,” said Chris Wright, senior vice president and chief technology officer at Red Hat, in a speech at the Linux Foundation’s Open Source Summit this fall. “So far, the community has more than 675 commits, more than 465 members and 20 organizations. In order to offer all of these features and become a widely available free service, we need to build trust. “

    This pursuit of partnership and trust has led Red Hat and IBM to partner with a variety of other large companies to support the Open Source Security Foundation. The Linux Foundation-led collaboration has already raised $ 10 million from the two companies and other celebrities including Amazon, Cisco Systems, Dell Technologies, Microsoft, Google, Oracle, and VMware.

    The initiative unites several projects under a single roof with the charter to find and fix security gaps in open source software. Open source visionary Brian Behlendorf, who was a co-creator of the Apache web server, is the general manager of OpenSSF.

    “These groups know that their stacks are largely made up of open source software, so they try to pass on these indirect dependencies,” Behlendorf said in a recent interview. “By improving the basis of open source, you end up getting higher quality code.”

    Cloud tools and ClusterFuzz

    Container security is also part of the software supply chain discussion. In addition to supporting OpenSSF, IBM announced in July that it would expand Sigstore to include the ability to verify the origin and integrity of a Kubernetes manifest with a cryptographic signature. This is to ensure that a resource has not been maliciously modified before it is applied to a Kubernetes cluster.

    IBM has also automated the query of Common Vulnerabilities and Exposures databases to reduce the risk of compromised packages and binaries being used in applications. The company’s Anaconda repository for IBM Cloud Pak automates this work for IT administrators.

    Amazon Web Services Inc. offers two separate tools that can help monitor supply chain security. One of them is AWS CloudTrail, which provides a log of all actions that have occurred in a user’s AWS environment. The other is Amazon CloudWatch, a monitoring and observability service for developers and IT managers. Logs, metrics, and events are collected to provide a unified view of AWS resource usage.

    Google recently upgraded its open source tool, ClusterFuzz, with an emphasis on improving the security of the software supply chain. In early November, the search giant announced the release of ClusterFuzzLite, which throws random data at computer programs to identify bugs that could be exploited by threat actors.

    The latest improvement is a result of Google’s OSS Fuzz project, which started five years ago to incorporate quality assurance into open source initiatives. An interesting sidebar from Google’s recent announcement was about the published data. The company found that OSS-Fuzz has identified 6,500 open source vulnerabilities and fixed 21,000 functional bugs to date.

    BOM solution

    Establishing a verified signature system and implementing tools to detect dangerous behavior or remediate vulnerabilities are steps in the right direction, but there are indications from US government officials that more transparency is needed. The Executive Order issued by the White House earlier that year called for a software bill of materials, or SBOM.

    This approach is similar to the one commonly used in the manufacture of goods. Just as manufacturers keep an inventory of all of the items in a given product, a software bill of materials would contain a list of all of the open source and third-party items contained in a code base.

    Basic information for an SBOM was developed by the National Telecommunications and Information Administration. The government is at least trying to make SBOM a requirement for software to be made available to federal agencies. It remains to be seen whether it will be accepted as a universal standard in the tech industry.

    “I’m a huge fan of the ongoing software BOM initiatives,” said Carielli of Forrester. “We need controls to track and manage software. Making new versions of open source software less vulnerable is an important initiative, but we cannot mistake this for some kind of magic bullet for the security of the entire software supply chain. “

    How the tech industry will ultimately respond to vulnerabilities in the software security supply chain is still a work in progress. Initiatives like Sigstore to address open source security concerns were a good place to start, but trust can be a difficult endeavor in a software ecosystem based on the sharing and global use of common tools. However, it will likely take trust as part of the open source ethos to provide an answer to today’s security problem.

    “We’re constantly pulling each other’s code, which demonstrates this high level of implicit trust,” Red Hat’s Wright said in a recent blog post. “Transparency, partnership, trust. That’s how we’ve done it in the past and that’s how we will do it in the future. “
