Me: I see that our BGP peering with you is up. We’re receiving prefixes from you and are advertising ours. Can you verify that you’re receiving them?
ISP: Yes, the session is up and we’re receiving them.
Me: Please verify that you’re advertising them upstream. They’re not reachable from the Internet.
ISP: Please conduct a pile of basic connectivity tests to the demarcation point with a laptop to verify basic connectivity.
Me: Wait. What? Are you new? #NetEng
Folks can say what they want about the relevance of certifications, but I’ll throw this out there: Even if we never write the tests, following the certification blueprint is a good approach to learning a technology without a lot of gaps in our understanding. #Certification#NetEng
If a vendor uses “our customers haven’t been asking for that” when pressed for #IPv6 support, it’s a big red flag that their product roadmap is tactical/reactive and not strategic/visionary. Expect the overall feature set to share this shortsightedness. #NetEng
Want your geoblocking to actually be semi-useful? Make sure your application prefers #IPv6. I’ve got four services that I regularly use but are geoblocked from my current location. One (IPv4-only) VPN connection later and I’m in. #NetEng#InfoSec
Signs you're a network engineer, first thought was not at all a car trunk, second thought was how a tagged person would show up on packet capture, then would the size of the shirt matter...
@renice#Discovery is red team. #DS9 is the beleaguered #neteng that keeps getting told there's no funding for a dedicated blue team. Except sometimes #section31 comes along claiming to be blue team, but they're really a bunch of self-motivated charcoal-hat cowboy coders on shadow projects. You're pretty sure most of them couldn't pass the company code of conduct policy tests. There's a persistent rumor they're going to get formally recognized as a skill team any quarter now.
#Voyager is that startup that never quite lands their IPO, and keeps having to seek new sources of VC funding along the way. They keep picking up new people, and the old hands can barely remember what it was like before seven years of 24/7 crunch time.
#Prodigy is that code #bootcamp that gets away with not charging for their services because the parent company accidentally bundled them with a datacenter's electric bill, where they're just noise in the budget.
#Picard is the local #Solaris users group that's all gung-ho about #Illumos. They've got some good points and originated some iconic features, but they're principally about nostalgia these days.
#tos is the retrocomputing club. Spectrum Sinclairs and Altairs line the walls, but are mostly for show. Someone converted an old IBM POWER workstation into a #Hackintosh so they could show Kid Pix to the kids. Everybody else spends their time showing off their DOS savegame files on the club's file server. One guy is playing DOOM in the corner with the music coming from an external Roland MIDI keyboard. Another guy figured out how to launch old DOS door games under containerized #dosemu instances via inetd, but people stopped talking to him once he solved the sandbox escape problem by having systemd launch the containers on-demand in a deprivileged chroot.
#StrangeNewWorlds is the club founded by that guy from the retrocomputing club that got DOS door games running via systemd; Now he's porting his door game collection to run in #webassembly, and has managed to reach a new generation of people respinning the classics.
#Enterprise is the #beos users group. Really a subgroup of the local retrocomputing club. They hate it, because people keep confusing their interests with Mac OS Classic and Linux.
