Upgrading Firmware on Northbound Networks Zodiac FX

Recent versions of firmware (after v0.80) running on the Northbound Networks Zodiac FX can be updated directly from the web interface, or using XMODEM via the serial console. But what if, say, you had sat one your Zodiac FX for a while and are running firmware earlier than v0.81 and have a sudden, unexpected desire to upgrade the firmware? Say you are, for example, me?

The process turned out to be less straightforward than I had hoped, so I am documenting the successful steps I followed in case it’s of use to somebody else.

My (Brief) Zodiac FX Background

Back in 2015 I backed a Kickstarter project for this awesome-sounding four-port FastEthernet SDN switch with OpenFlow support. It sounded so cool that I even ordered a two-pack as I thought it would be more fun to have two OpenFlow switches to mess around with). The project was funded successfully, but embarrassingly when the beautifully-made boards arrived in early 2016, for some reason I never quite got around to playing with them. I think it was in part because it was just a printed circuit board without a case and without easy access to 3D printing I was turned Continue reading

SEC 3. Building your own containerised PKI (root CA) with Linux and Docker to simplify and secure network automation

Hello my friend,

You know our passion to network automation. We truly believe, that this is the only sustainable way for the network development and operation. In the same time, one the key goals of the automation is to make your network secure and safe. Therefore, the security of the automation and communication channels used by automation is very important. So today we’ll take a look how to build

Can automation make your network better?

Automation is the key component of the perpetual engine of your network development and operation. It allows you to run the network quick, stable, and safe. And we are willing you to benefit as much as you can from that.

We have created a new training, which is focused only on the Nornir and you can use it for the network (and not only) automation. It is an organic extension of our network automation training, which assumes you are already Continue reading

Smart ways to compare files on Linux

Commands for comparing files have proliferated since the early days of Linux. In this post, we'll look at a suite of commands available for comparing files and highlight the advantages that some of the newer ones provide.diff One of the oldest and still popular commands for detecting and reporting on file differences is the diff command. Comparing two lists of meeting attendees, the diff command will simply and clearly show you the differences.$ diff attendance-2020 attendance-2021 10,12c10 < Monroe Landry < Jonathon Moody < Donnell Moore --- > Sandra Henry-Stocker Only the lines that are different are displayed.

On the ‘net: The Art of Conviction

I was recently a guest on The Art of Conviction podcast, where we covered a bit of my background, some of the challenges I’ve faced in getting where I am, and then we moved into a discussion around my recently finished dissertation. I’m working to find places to publish more in the area of worldview and culture; I’ll point to those here as I can find a “home” for that side of my life.

You can find the recording here.

Beyond my episode, The Art of Conviction is a fascinating podcast; you should really subscribe and listen in.

Industry-First Pay-as-you-go SaaS Platform for Kubernetes Security and Observability

We are excited to introduce Calico Cloud, a pay-as-you-go SaaS platform for Kubernetes security and observability. With Calico Cloud, users only pay for services consumed and are billed monthly, getting immediate value without upfront investment.

Introduction

Calico Cloud gives DevOps, DevSecOps, and Site Reliability Engineering (SRE) teams a single pane of glass across multi-cluster and multi-cloud Kubernetes environments to deploy a standard set of egress access controls, enforce security policies, ensure compliance, get end-to-end visibility, and troubleshoot applications. Calico Cloud is Kubernetes-native and provides native extensions to enable security and observability as code for easy and consistent enforcement across Kubernetes distributions, multi-cloud and hybrid environments. It scales automatically with the managed clusters according to the user requirements to ensure uninterrupted real-time visibility at any scale.

Security and Observability Challenges

  • North-South Controls: Often microservices need to communicate with services or API endpoints running outside the Kubernetes cluster. Implementing access control from Kubernetes pods to external endpoints is hard. Most traditional or cloud provider’s firewalls do not understand the Kubernetes context which forces the ops team to allow traffic from the entire cluster or a set of worker nodes.
  • East-West Controls: Even after effective perimeter-based north-south controls, the organizations face challenges to Continue reading

How to Deploy GPU-Accelerated Applications on Amazon ECS with Docker Compose

Many applications can take advantage of GPU acceleration, in particular resource-intensive Machine Learning (ML) applications. The development time of such applications may vary based on the hardware of the machine we use for development. Containerization will facilitate development due to reproducibility and will make the setup easily transferable to other machines. Most importantly, a containerized application is easily deployable to platforms such as Amazon ECS, where it can take advantage of different hardware configurations.

In this tutorial, we discuss how to develop GPU-accelerated applications in containers locally and how to use Docker Compose to easily deploy them to the cloud (the Amazon ECS platform). We make the transition from the local environment to a cloud effortless, the GPU-accelerated application being packaged with all its dependencies in a Docker image, and deployed in the same way regardless of the target environment.

Requirements

In order to follow this tutorial, we need the following tools installed locally:

For deploying to a cloud platform, we rely on the new Docker Compose implementation embedded into the Docker CLI binary. Therefore, when targeting a cloud Continue reading
