The next New Hampshire Networking User Group (NH)NUG is happening on April 16, 2025 in Manchester. Venue TBD, but probably Stark Brewing.

CFP! We want to mix up format with lightning talks. You got ~15 minutes to share something? LMK!

HN763: You Too Can Say ‘Yes’ to Packet Analysis Packet capture and packet analysis is incredibly useful for problem-solving and troubleshooting. Analyzing packets is also a difficult skill to master. With the incredible array of network troubleshooting tools at our disposal, including emerging netwo...

With the advent of AI doing ever-deeper analysis of network traffic and providing actionable insights, do network engineers need to do packet analysis anymore? This & more are discussed by me and Chris Greer in this episode of Heavy Networking.

N4N008: What Is a Default Gateway? Today’s topic is the default gateway, essential for routing traffic between networks. We explain its purpose, configuration, and the consequences of incorrect settings. Using home networks as an example, Ethan and Holly illustrate how default gateways ...

In this week's N Is For Networking (a podcast for new networkers), we discuss the default gateway. How does a host know when a destination is local & when it needs a gateway to forward traffic on instead? We keep the answer simple without dumbing it down.

Thanks for saying so, Laura. 😀

Netlab can also orchestrate physical gear and integrate it with virtual. Thus, the 2 extra routers and switches give me some topology options for larger labs if my main server runs out of RAM or cores while still integrating with the netlab ethos.

The magic of netlab is defining the lab via YAML, and then up it comes with all the crap work of assigning IP addresses and building routing adjacencies handled automatically.

Spent my afternoon working on a lab environment that will be a foundation for YouTube content. It's a mix of an Ubuntu server I'm running Ivan Pepelnjak's netlab on, plus a couple of older physical switches and routers I picked up cheap on eBay. 3560X-24 + 4948 switches, 2951 + ISR4321 routers.

A friend of mine at a company I think highly of is hiring for a developer evangelist role. The right person (you?) is excellent in a public-facing role and deeply knowledgable about network automation. If you’d like to know more, DM me. The role is not being publicly advertised.

VMware Fusion and Workstation are Now Free for All Users These powerful desktop hypervisor products are free to all users - commercial, educational, & personal users alike!

Hey, VMware Fusion & Workstation users. So, it's free now. Are you still using it, or have you moved on, because Broadcom?

If you've moved on, what are you using instead, and what's your use case?

You had me at shoegaze.

The Problem With Network Automation Certifications As I’ve reviewed network automation certs, I find that they are teaching products and techniques specific to a vendor ecosystem or tool environment. There's nothing wrong with those certs. You'll lear...

I wrote a thing. For saying so little, I'm not sure why it took several hours of fussy editing before I finally hit publish and sent it into the void.

Jupiter now scales to 13 Petabits per second | Google Cloud Blog Google networking leaders reflect on the milestones that led to Jupiter supporting 13 petabits per second bandwidth, and what comes next.

Huh. That doc is going in my reminders app to read. Deep buffered leafs are counterintuitive considering the use case.

Well...Apple made up my mind for me. The price of a Max is stupid high when I'm not daily driving an app that needs it. After trying different builds, I ordered an M4 Pro with 48GB RAM for less than the cost of an M4 Max with 32GB.

When Uncle Tim releases the M4 MBPs today, I'm thinking of a 16" M4 Max. I'm currently rocking an M1 Pro. I don't *need* a Max. I rarely do video rendering. Not much of a gamer these days. But from what I'm reading, the battery hit isn't that bad.

Anyone with a 16" Max got a comment on battery?
