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

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

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

Jody Lemoine 🇨🇦 @ghostinthenet.bsky.social · Aug 28

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

Is it just me, or have technical forums devolved to the point where every question about if there’s a way to do something produces responses asking the OP to justify their reasons for wanting to do it...

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?

Jody Lemoine 🇨🇦 @ghostinthenet.bsky.social · Aug 10

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.

More than once, I’ve seen folks narrowing the concept of “enterprise” organizations to include only largest fraction of a percent of businesses lately. Admittedly, large organizations (above 500 emplo...

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.

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
