PP006: Effective Security for Small IT Shops
This episode is for IT professionals who work in small- to medium-sized businesses and are expected to handle cybersecurity on top of issues like “my camera isn’t working on Zoom.” Guest Joe Stern has been filling this role for an 80-person company for almost 30 years. We talk about how he prioritizes risks, security tools... Read more »3GPP Standards for Satellite IoT – Catalyst for Progression?
With low earth orbit (LEO) satellites fast becoming the norm and 3GPP unifying telecom standards around the globe, the satellite IoT and machine-to-machine (M2M) sector ought to be looking at a bright horizon. But is this the case?Interface EBGP Sessions on Arista EOS
Arista EOS and Cisco Nexus OS got interface EBGP sessions years after Cumulus Linux. While they’re trivially easy to configure on FRRouting (the routing daemon used by Cumulus Linux), getting them to work on Arista EOS is a bit tricky.
To make matters worse, my Google-Fu failed me when I tried to find a decent step-by-step configuration guide; all I got was a 12-minute video full of YouTube ads. Let’s fix that.

Tech Bytes: Protecting Connected Medical Devices With Palo Alto Networks IoT Security (Sponsored)
Medical devices are an essential element of patient care. They’re also network-connected devices that need resilient connectivity and security. On today’s Tech Bytes we examine the challenges of supporting and securing connected medical devices, including threats, vulnerabilities, and regulatory frameworks. We’ll also discuss strategies and best practices to manage medical device risks and ensure the... Read more »NB470: NetBox Labs Adds On-Prem Support; ASML Vs. The Netherlands
This week on Network Break we discuss a new on-prem version of NetBox Labs’ source-of-truth software with enterprise support, why Selector AI is adding an LLM to its operations and observability product, and whether a new Web application firewall from Cloudflare can protect LLMs against malicious prompts. Viavi Solutions consolidates the network testing space with... Read more »AI Assistants
I have written elsewhere about the danger of AI assistants leading to mediocrity. Humans tend to rely on authority figures rather strongly (see Obedience to Authority by Stanley Milgram as one example), and we often treat “the computer” as an authority figure.
The problem is, of course, Large Language Models—and AI of all kinds—are mostly pattern-matching machines or Chinese Rooms. A pattern-matching machine can be pretty effective at many interesting things, but it will always be, in essence, a summary of “what a lot of people think.” If you choose the right people to summarize, you might get close to the truth. Finding the right people to summarize, however, is beyond the powers of a pattern-matching machine.
Just because many “experts” say the same thing does not mean the thing is true, valid, or useful.
AI assistants can make people more productive, at least in terms of sheer output. Someone using an AI assistant will write more words per minute than someone who is not. Someone using an AI assistant will write more code daily than someone who is not.
But is it just more, or is it better?
Measuring the mediocratic effect of using AI systems, even as Continue reading
Running netlab and BGP Labs on Apple Silicon
I usually say that you cannot run netlab on Apple silicon because the vendors don’t provide ARM images. However, when I saw an ARM version of the FRRouting container, I started wondering whether I could run the BGP labs (admittedly only on FRR containers) on my M2 MacBook Pro.
TL&DR: Yes, you can do that.
Now for the recipe:

Worth Reading: History of Ethernet
The March 2024 Internet Protocol Journal has a lengthy article on the history and “future” of Ethernet that might be worth reading (although it’s short on details) if you weren’t around when it all started.

Containerlab – Creating Network Labs Can’t Be Any Easier
What if I tell you that all you need is just a YAML file with just a bunch of lines to create a Network Lab that can run easily on your laptop? You'd call me crazy, right?
Well, in this blog post, I'll walk you through what Containerlab is and how it can simplify creating and managing your labs with ease. Let's dive in.
What we will cover?
- What is containerlab?
- Comparing EVE-NG/GNS3 to Containerlab
- Installation and initial setup
- Lab images (Arista cEOS)
- Containerlab terminology
- Lab example
- Cleaning up
- Closing thoughts
Cisco Restconf - Get Operational Data
In this blog post, we’ll use Restconf to pull operational data from a Cisco switch. So far in our previous posts, we’ve looked at getting and changing configuration data.

What is Containerlab?
The official definition is "Containerlab provides a CLI for orchestrating and managing container-based networking labs. It starts the containers, builds a virtual wiring between them to create lab topologies of users choice and manages labs lifecycle."
Simply put, containerlab is a Lab-as-a-code tool that helps you set up and manage your network labs easily. Instead of dealing with complex setups and configurations, containerlab simplifies everything for you. Continue reading
HN725: Standing up a DC Network Using Terraform
Matt Horn built a data center network through automation, remotely. This is the future of network engineering. Matt shares how his team did it technically: Terraform, a little Ansible, leveraging pipelines, etc. But he also shares the processes and culture that made it happen: Management and peer buy-in, tight enforcement based on user access, and...

Urs Baumann invited me to have a guest lecture in his network automation course, and so I had the privilege of being in lovely Rapperswil last week, talking about the basics of real-life network automation.
Urs published the video recording of the presentation on YouTube; hope you’ll like it, and if you don’t get too annoyed by the overly pushy ads, watch the other videos from his infrastructure-as-code course.
