The way to your solution
Introduction When you’re running a virtualized environment, keeping the network smooth and steady is key—especially for apps that use UDP. Unlike TCP, UDP doesn’t bother with resending lost packets, so when something goes missing or arrives late, things can go sideways pretty fast. That’s a big deal for real-time stuff like VoIP, video calls… and yes, even faxing. In one of the previous projects I worked on, we used fax
Let’s be honest — keeping a fleet of Ubuntu servers updated isn’t the most glamorous job, especially when they’re tucked away behind firewalls with no internet access. But what if we could turn this dusty chore into a clean, elegant, and even satisfying little automation adventure? That’s exactly what we did. This was actually my first real project using Ansible, and it turned out to be a fantastic way to
Dell’s Integrated Dell Remote Access Controller (iDRAC) is an essential tool for managing Dell PowerEdge servers remotely. However, losing access due to a forgotten password can be a challenge. If you have ESXi installed on your server, you can reset the iDRAC password directly from the ESXi shell using the RACADM tool. This guide walks you through the process step by step. Prerequisites Before proceeding, ensure that: Using the RACADM
Recently, I encountered an issue where I was unable to access the vCenter web interface in my Test-Lab, after restoring to a pretty old Snapshot. Upon attempting to log in, I was met with the errors “No healthy upstream” and “503 – Service Not Available” on the management interface. This blog post outlines how I debugged and resolved this issue, which turned out to be caused by an expired certificate.
Managing a vCenter environment with multiple Datacenters and Clusters can quickly become a complex and time-consuming task, especially when dealing with repetitive operations like adding or renaming Datastores. Inconsistent naming conventions, manual errors, and scalability challenges often complicate matters further. Automation offers a powerful solution. By leveraging PowerShell scripts tailored for vCenter, you can simplify routine tasks, enforce consistency, and significantly reduce the risk of human error. In this post,
Accidentally deleting a datastore in a VMware ESXi environment can feel like a catastrophic event, especially when the datastore is shared across multiple hosts. In this article, we’ll discuss the step-by-step process of recovering a deleted datastore, specifically when it was removed from one ESXi host and subsequently disappeared from all associated hosts. The goal is to help you understand the available recovery options and ensure data is restored with
Monitoring the health of a virtualized environment is very important to maintaining uptime and detecting potential issues early. VMware vCenter 8 provides robust alarm and notification features that allow system administrators to be promptly alerted via email when specific conditions occur. In this guide, we’ll walk you through the process of configuring email notifications and setting up alarms in VMware vCenter 8. This post contains affiliate links. If you buy
Managing server hardware remotely is essential in modern IT environments. HPE’s Integrated Lights-Out (iLO) provides remote management capabilities for HPE ProLiant servers. One of the tools to configure and manage iLO is HPONCFG. This utility allows administrators to configure iLO settings without having to reboot the server or restart services, making it a powerful tool for system management. In this post, we will cover how to use HPONCFG on both
When it comes to managing IT infrastructure, the Hewlett Packard Enterprise (HPE) Integrated Lights-Out (iLO) interface is a game-changer for making server administration easier and more efficient. HPE iLO allows administrators to manage servers remotely, providing capabilities such as system health monitoring, power management, and configuration without the need for physical access. One of the key features of iLO is its support for Secure Shell (SSH) commands, which enable secure
In the world of virtualization, managing resources efficiently is super important. If you’re an administrator dealing with virtual environments, using the right tools is a must. That’s where PowerShell comes in—a really helpful tool that can make managing VMware snapshots easier, so things run smoothly and problems get solved fast. Simplifying Virtual Management with PowerShell Imagine a world where things happen quickly and accurately. That’s exactly what PowerShell does. With
