I installed the Azure CLI in the Termux app on my Android phone. This post describes all the steps required to successfully run Azure CLI on most Android phones. Installing Azure CLI on Termux on your Android phone is an alternative to using Azure Cloud Shell on Chrome or Firefox, or to using the Cloud […]
I want to show you how to configure a host server so, when it is shut down, it executes a script that runs commands on any running virtual machines before the host tries to stop them. I will configure the host server to wait until the script completes configuring the virtual machines before continuing with
Yesterday, I participated in a screen-cast with Derick Winkworth, aka @CloudToad, to discuss my blog posts about installing NRE Labs Antidote network emulator on your PC and creating lessons for NRE Labs. We also covered some general points like contributing to communities, how to get started blogging about technical topics, and more. Check it out,
The Antidote network emulator, part of the Network Reliability Engineering project, offers a web interface that presents network emulation scenarios to users as documented lessons. Each lesson is presented in a window running Jupyter Notebooks and contains commands that the user can click on to run them on the virtual nodes in the network emulation
Antidote is a network emulator combined with a presentation framework. It was designed to create and deliver networking technology training. Its user interface operates in a web browser, including the terminals that students use to run commands on emulated network devices and servers. Antidote is the engine that runs the Network Reliability Labs web site.
Wistar is an open-source network emulator originally developed by Juniper Networks and released under the Apache license. It simplifies the presentation of Juniper products on its graphical user interface by making the multiple VMs that make up each JunOS virtual router appear as one node in the network topology. Wistar also supports Linux virtual machines
Vrnetlab, or VR Network Lab, is an open-source network emulator that runs virtual routers using KVM and Docker. Software developers and network engineers use vrnetlab, along with continuous-integration processes, for testing network provisioning changes in a virtual network. Researchers and engineers may also use the vrnetlab command line interface to create and modify network emulation
In this post, I demonstrate how to create a network emulation scenario using Libvirt, the Qemu/KVM hypervisor, and Linux bridges to create and manage interconnected virtual machines on a host system. As I do so, I will share what I have learned about network virtualization on a Linux system. Libvirt provides a command-line interface that
Are you like me? Are you a network engineer, or other professional, transitioning their skill set to include programming and automation? Does your programming experience experience come from a few programming courses you attended in college a long time ago? Then please read on because I created this Python guide for people like you and
