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

as a neteng, there is nothing more infuriating and harder to debug network issues than double NAT.

Several decades of NetEng and SysAdmin/cloud experience say check DNS and firewalls a week before doing anything. Old habits die hard

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

i've made millions of cat5/6 cables (im a neteng). nah they don't wear out and short runs of cat5e do 10gig speeds just fine.
it's the RJ45 head that crimps onto the end of the cable (and wires inside) that will sometimes eventually come loose.
the more you know! 🌈

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 worked in neteng specifically but in systems/software, and I doubt it’s very different.)

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

If there's one thing I can count on it's work putting me in a situation where I have to quote RFCs at people. This time being RFC4364 which is a nice change of pace to break off the neteng rust

I’ll be speaking at Cloudflare Connect in Las Vegas on Oct 16 about resilience in distributed systems. Not just redundancy, but how clients, protocols, applications, and infrastructure each need to handle failure without assuming the others will work.

Did you use SecureCRT in NetEng?A CIA analyst sent to confirm the election wasn't rigged.
He found they used a terminal emulator to access voting machines via RS232 & code adds to flip votes Harris to Trump. They Discovered they had root access without login or change logs.

Man. On Tuesday I was bait and switched with a poisoned chalice move that my company's trying to rush me into accepting. And today it feels like I was handed the jade seal after a friend said a dozen people independently name dropped me to replace a core neteng at other company

Last position, hired to implement FW's. My 1st day I walked in to find no desk and two of the team in NetEng told me "Don't think you are going to install FW's here-it's not going to happen. This was a prestigious University with almost 70,000 students-Dah! I stayed for 8 years in that shit hole.
