Proof of concept lab complete (RFC 1925 Truth 1 has been satisfied) and my MikroTik Professionals Conference presentation request has been submitted. Now to start working on the actual presentation in case they actually say yes. #MTPC #MikroTik #NetEng

The problem with labbing cool networking ideas? Rabbit holes. Every step along the way, there’s another “Oh! Wouldn’t it be better if I integrated •this• idea?” Taking the red pill leads to a fun day of network geekery, but doesn’t get me any closer to the original goal. The “Simplicity where possible. Complexity where necessary.” mantra applies long before we get to the design stage. #NetEng #Labbing #RabbitHole #KISS

Reading articles like https://www.proxylity.com/articles/udp-is-a-convertible.html frustrate me as you are assuming you have a reliable connection. I do not. My ISP drops/reorders packets all the time, WiFi makes it even worse. "Just build a TCP light on top of UDP" isn't an answer. Yes the answer is to make the infra better, but until you can convince the cable and telcos to go all FTTP we need good software to cover up the failing infra the bulk of your users are stuck with. #neteng

UDP Isn't Unreliable, It's a Convertible - Proxylity Blog

Explore why UDP isn't truly unreliable and how you can build custom reliability layers that give you the best of both UDP and TCP worlds.

Just took an exam given by Pearson Vue. The last time I took one (outside of Cisco Live), I had to drive 2+ hours to get to the closest exam center. Today, it took 4 minutes and only because I took the long way.

Discovering that something is a DNS problem rather than a network problem feels good… until we learn to accept the fact that DNS is a fundamental network service. If it’s DNS, it’s the network. The real joy comes from it not being •my• network’s DNS that’s at fault. #NetEng #DNS

After two weeks of off-and-on banging my head against this multicast routing lab, I finally found the problem. The default TTL for •all• multicast packets on Linux is… 1. Of course, I overlooked all of the simple stuff in my troubleshooting, as one does. #NetEng #Multicast #Troubleshooting #LessonLearned #ThereAreDays #Sigh

I found an old Azure deployment that makes my eye twitch. The resource group, vnet, virtual machine, K8S service, security group, and route tables all have the same name.

Don't do that.

Just ran across a normal Azure VM with "bastion" in the name. Don't do that.

I haven’t played extensively with multicast routing for a little over a decade, but here I am grinding the rust off of the metal. Gotta stay fresh if I want to engage in silly proof-of-concept labs. #NetEng #Multicast #Labbing #WorthIt
