Nornir is a Python-based framework that automates fussy, backend details to let you focus on business logic. On today's Heavy Networking, we explore this project, how it works, and what it can do in your network, with three of Nornir's contributors.
The post Heavy Networking 445: An Introduction To The Nornir Automation Framework appeared first on Packet Pushers.

Do you like this sort of Stuff? I'd greatly appreciate your support on Patreon. I wrote Explain the Cloud Like I'm 10 for people who need to understand the cloud. And who doesn't these days? On Amazon it has 45 mostly 5 star reviews (103 on Goodreads). They'll learn a lot and hold you in even greater awe.
Young people everywhere are building technology, mobilizing communities, and raising their voices to shape policies that create an Internet that’s truly for everyone.
That’s why we’re partnering with the not-for-profit and non-governmental organization AIESEC on a pilot project to train 500 young people on Internet-related skills in Bolivia, Nepal, Namibia, and Kenya.
It’s our hope that this project will be the start a journey that will result in even more young voices joining a community of thousands of people around the world who believe in the open Internet.
Young people like Pamela Gonzales.
At only 24 years old, Gonzales is the co-founder of Bolivia Tech Hub, an early stage incubator that serves as one of La Paz’s only support systems for the city’s tech community, helping entrepreneurs to learn, develop, and collaborate on new projects.
She’s impacting hundreds of lives, but she says it didn’t come easily.
In her first year of university, she partnered with a friend of hers, a local web developer, and together they secured funding and built something new.
“My mission was to find a place to learn the things I couldn’t learn in the university,” Gonzales said. “I found there were a lot of students Continue reading

Have you ever thought about the increasing disorder in your life? Sure, it may seem like things are constantly getting crazier every time you turn around, but did you know that entropy is always increasing in the universe? It’s a Law of Thermodynamics!
The idea that organized systems want to fall into disorder isn’t too strange when you think about it. Maintaining order takes a lot of effort and disorder is pretty easy to accomplish by just giving up. Anyone with a teenager knows that the amount of disorder that can be accomplished in a bedroom is pretty impressive.
One place where we don’t actually see a lot of disorder is in the computing realm. Computers are based on the idea that there is order and rationality in everything that we do. This is so prevalent that finding a way to be random is actually pretty hard. Computer programmers have tried a number of ways to come up with random number generators that take a variety of inputs into the formula and come up with something that looks sufficiently random. For most people just wanting the system to guess a number between 1 and 100 it’s not too bad. But Continue reading
Each day, more and more of us buy products that connect to the Internet, such as personal assistants, fitness monitors, appliances, and home security systems. Odds are you have one, two, or even more. There are more than 23 billion of these Internet of Things (IoT) products installed around the globe – roughly triple the world’s population – and that number is growing.
The Internet of Things offers the promise of convenience, efficiency, and more personalized services. However, many of these products are designed with little consideration for basic security and privacy protections.
The Internet Society and Consumers International formed a working partnership last year to address these challenges and to make sure consumers have access to trusted Internet-connected devices. We are proud to be lead partner at the Consumers International Summit, 30 April – 1 May, focused on putting consumers at the heart of digital innovation.
Consumers care deeply about their privacy, security, and how their personal information is collected and handled. On May 1 at the Summit, our President and CEO Andrew Sullivan will unveil new research from Consumers International and the Internet Society exploring what matters most to consumers when buying connected devices. He will also Continue reading

My first Cisco router was a blade for a Cabletron modular hub (anyone remembers what hubs were or a company named Cabletron?). We plugged it in, I read the documentation, figured out I had to type conf t and was faced with a blinking cursor staring back at me from an empty line.
A few years later I was invited to beta test Cisco software release 9.21 (it wasn’t called IOS yet). The best feature it had was the awesome configuration CLI with context-sensitive prompts and on-demand help.
Read more ...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 and, interestingly, uses cloud-init to configure Linux routers from the Wistar user interface. Wistar also supports generic virtual appliances, in a basic way. In this post, I will install Wistar and use it to work through two examples using open source routers.
The Wistar installation procedure is documented in the Wistar GitHib page. The Wistar user guide is available at the Read the Docs website and some unpublished chapters are available on GitHub. Juniper published a presentation about using Wistar. In addition, there are a few other other blog posts available about using Wistar and comparing Wistar to other network emulators.
Wistar documentation is good enough to get started, but seems to be incomplete.
I installed Wistar on my laptop computer running Ubuntu 18.04 LTS. I modified the Wistar Continue reading
