The “Simplicity where possible. Complexity where necessary.” mantra applies long before we get to the design stage. 2/2 #NetEng #Labbing #RabbitHole #KISS

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. 1/2

I’m surprised I don’t misplace my military driver’s license (DND 404) constantly. #GeekJoke

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 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 the simple stuff in my troubleshooting, as one does. #NetEng #Multicast #Troubleshooting #LessonLearned #ThereAreDays

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 #Milticast #Labbing #WorthIt

“Something went wrong. Please try again later.” as an error message is about as helpful as “It’s broken.” is. Not only is the first part so vague that it’s useless to anyone who might be able to help, but we •know• that trying again later is unlikely to work either. #Grr

Red and white Corgi, flat on his back and with his paws in the air.

Apparently it’s one of •those• days again. #CorgiLife

An IPv6 address is composed of 8 16-bit quybbles (quad-nybbles) and this shall be the standard term used in all of my documentation going forward. #NetEng #Quybble #BecauseItMakesMeSmile #IHaveSpoken

“The standard that you walk past is the standard that you accept.” - LGen David Morrison. Simple phrase, but infinitely powerful. #Leadership #ThingsToLearn

Today I learned that my approach to leadership is actually an established method. Need to read some of Robert K. Greenleaf’s stuff sooner than later. #Leadership

Favourite use of ANI so far? Auto-generated transcripts for videos and podcasts. #NoTime #LetMeSkimThat #MyPace #AI

Some days I wonder if the companies that are so keen on using ANI to streamline their processes and eliminate jobs are considering that their customers are simultaneously using ANI to kill the need for their products and services. #AI

#NetEng #AI #Forums

To those who keep asking, no. I’m not worried about ANI taking my job. Well, no more so than I am about my screwdrivers taking my job. The practitioner is always more than the sum of their tools. #AI

I would place businesses above 1,000 employees in the ultra-large category. That’s 500 above large, which is already the top 0.3% of businesses. Networking practitioners would be anyone specialized in networking. I agree that there’s a critical mass needed for those, but how much?

If (approximately) one in four people are employed by ultra-large businesses, do networking practitioners have a similar distribution? My experience in discussions with my peers indicates that we’re skewed heavily toward that market, perhaps four in five or even nine in ten. #NetEng

why does enterprise software UI absolutely suck?
you get engineers with a sense of superiority because they “got gud“

bro, you have stockholm syndrome from an aruba controller, and you’re telling me to git gud? get outta here.

The products of #AI aren’t subject to copyright. Does this mean organizations who are vibe coding have no intellectual rights to the results? I’m thinking the answer is yes. If I’m right, I now wonder if these organizations have considered this… or have they been too caught up in the hype?

If we outsource our customer service, it can be fairly said that we’re not serving our customers at all. Now let that sink in.

It absolutely does. Then again, the bulk of HTTPS/QUIC requests go to servers that host multiple sites, so IP literals are becoming less and less useful.

DNS Bypass Mitigation with RouterOS Can we block unauthorized use of DoH and DoQ from clients on our network without breaking HTTP and QUIC? Let's find out...

I came across the phrase "all hat and no cattle" today. I haven't heard that one in •years• and now need to re-add it to my lexicon.

#Cisco #IOS #NetEng

A first principle in network security is to minimize or eliminate the attack surface. I refer to this as the Miyagi Rule, quoting the iconic sensei from “The Karate Kid” in the 1980s: “Best way to avoid punch... no be there!” #InfoSec #NetEng

Okay, •now• you can tune in to the livestream. Technical issues. Sigh. #NFD38

What?! AI for the sake of AI isn't a thing anymore? There needs to be a business case? Say it ain't so! 😉 cPacket seems to get it here. #NFD38
