There’s always another 🕳️ to go down. Now it’s a packet-level analysis of raw L2TPv3 pseudowires vs UDP encapsulated ones to find out •why• the raw ones come in with a lower automatic MTU than the UDP ones do. On the surface, this makes no sense. #NetEng #Labbing #L2TP #MTU #TunnelsAllTheWayDown

Companies hiring for junior positions that need years of experience should raise an eyebrow. Organizations that aren’t hiring for junior positions at all should raise both.

Companies have been making excuses about developing their people for years with that tired “But what if we train them and they leave?” mantra. At the very same time, they’re only looking to hire folks with existing experience from organizations that •did• develop their people. There’s a disconnect.

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

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

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

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

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.
