With all the changes in VMware’s offerings, sysadmins and businesses are looking for alternatives to reduce expenditure or have more control over their infrastructure. Proxmox is a free enterprise-ready alternative to VMware ESXi with optional commercial hypervisor and backup support.

The instructions in this post outline how to execute arbitrary code with administrator privileges on the Windows logon screen before the user signs in.

In a previous post, I covered Podman Desktop, an alternative to Docker Desktop. Today, I will look into Podman 5.0, the latest iteration of Red Hat's free open-source container engine. The new release brings significant enhancements, including revamped container engine code for Windows and macOS, native Apple Hypervisor support, and streamlined image building for Podman farms. Let's explore the new Podman 5.0 features and improvements.

The remediation of CVE-2023-24932, discovered in May 2023, is taking longer than Microsoft's initial timeline. This flaw allows attackers to bypass Secure Boot and disable security features like BitLocker. The April 2024 update introduces a new fix that admins should thoroughly test because it has significant ramifications and will be automatically activated in October.

Azure App Service Automatic Scaling is a new feature that intelligently manages the number of instances of a web application. It analyzes real-time HTTP traffic and scales out (adds instances) or scales in (removes instances) to match demand. The most significant advantage of Automatic Scaling is that it simplifies web application management, offering a less complex approach than services like Azure Virtual Machine Scale Sets (VMSS) or Azure Kubernetes Service (AKS), which often require detailed rule definitions.

Active Directory and Entra ID (formerly known as Azure AD) have their own password policies to prevent users from using weak and insecure passwords. While these policies can be combined, the level of protection achieved through this approach is still limited.

Microsoft 365 has deprecated the search-mailbox cmdlet, a decision that has faced considerable resistance from numerous Exchange Online administrators. In this post, I aim to examine the consequences of this cmdlet's removal and discuss viable alternatives and potential solutions.

GitHub Actions workflows for GitHub Pages just became generally available. GitHub Pages is a service that lets you host static websites on GitHub directly from your repositories. GitHub Actions is a continuous integration and continuous delivery (CI/CD) platform provided by GitHub that allows users to automate their build, test, and deployment pipelines. This article takes you through using custom workflows to deploy static websites to GitHub Pages with GitHub Actions workflows.

HashiCorp changed Terraform's license from open source to Business-Source License (BSL). Soon after, the open-source fork OpenTofu became available. OpenTofu is an infrastructure-as-code (IaC) tool that allows you to define and manage your infrastructure in configuration files. In this post, I demonstrate with a practical example how to create an EC2 instance in AWS with OpenTofu.

PowerApps is a low-code platform from Microsoft that enables businesses and individuals to quickly build custom applications for web and mobile, connecting to various data sources without extensive coding experience. I'm new to PowerApps and initially relied on guides on the internet to build my first app. The app was simple: collect user input and send it to Power Automate for processing. However, online guides can sometimes be outdated, and I ran into trouble with a deprecated Power Automate trigger called 'Ask in PowerApps.' The recommended solution is to use the newer PowerApps V2 trigger; this guide will show you how.

Windows Passkeys, introduced with Windows 11 23H2, is a passwordless sign-in solution that uses your Windows Hello credentials (face, PIN, or linked device) for secure and convenient authentication to websites and apps. This guide will teach you how to create, use, and manage a passkey using Windows Hello.

The Windows setup goes through several phases, with the last one being the Out-of-Box Experience (OOBE). It presents users with multiple dialogs for system configuration. Some settings are security-related, while others may be unclear to many users. Using an answer file, they can be automatically customized.

Ansible Vault allows you to encrypt sensitive data such as passwords, keys, and other secrets rather than storing them as plaintext in your playbooks or roles. In this tutorial, I will explain how to use Ansible Vault to encrypt and decrypt data during playbook runtime.

Microsoft Outlook has long allowed you to process incoming and outgoing emails using rules. You will no doubt be familiar with them. They allow you to move emails to different subfolders, set categories, auto-cc additional people, or automatically delete emails. I have recently stopped using Outlook rules and have started using Power Automate instead. Although working with emails directly is limited in Power Automate, the platform allows for expansion beyond traditional rule sets by integrating with other Office applications and third-party services.

I wanted to let you know that we have added a new model to 4sysops AI called Perplexity PPLX 70B Online. What sets this model apart is that it conducts an online search for every query and summarizes the content from the first few result pages. This approach has the advantage of providing access to timely information.

iVentory allows for easy Windows 11 deployment using a PXE server. The solution includes a DHCP server, provides image management, including automation through answer files, and can be managed via a web console. It's free for private and 49 USD per server for commercial use.

A severe vulnerability (CVE-2024-3094) has been discovered in XZ Utils (5.6.0 or 5.6.1), a commonly used compression format. The vulnerability allows attackers to gain root access through SSH. XZ Utils is used in many Linux distributions; it is also available for Windows and has been incorporated into many other programs. Attackers can install programs, manipulate data, or create new accounts with full root privileges. While there are no reports of exploits in the wild, the potential impact is profound, and most Linux distributions have issued warnings. In this post, you will learn how to determine if your systems are affected and what to do if they are.
