It was a fun session again, interesting traces to chew on :-).
The packet doctors are in session analyzing trace files live that they’re seeing for the first time! . #Wireshark #sf24eu #packetdoctors

UPDATE: Turns out when the T0 and the HCX-NE are on the same host, there is an ARP entry in the logical-switch, but no MAC entry in it (as no VTEP is involved in forwarding). But a neighbor (L2) entry is listed in the logical-router pointing to the portgroup of the HCX_NE.

When using HCX Network Extensions, how does the NSX-T0 gateway send traffic for a brdiged VM to the local NE VM?.In NSXCLI, I do see an ARP enry, but no entry in the MAC (VTEP) table. I can't seem to find relevant documentation online. #HCX #NSX @VMware @vmwarensx @vmware_nl.

Great class to join if you’re relatively new to #Wireshark. And if you want to beef up your filtering if in Wireshark too, join my class too, straight after their class! Hope to see you at #sf24us.

Looking forward to touch this masterclass @ Sharkfest US in June!. #wireshark #displayfilter #bpf #sf24us.
Don't miss @SYNbit's pre-conference class @#sf24us!. Take your filtering skills to the next level. Go through basic operators/advanced filtering (display filter macros/dynamic filters/regex, etc.). Also learn to use BPF filters while capturing #pcap files.

Wellicht goed om de "Aflevering wijzigen" die 2x in de mail staat eruit te verwijderen als dat toch niet kan.

Hallo @UPS_Netherlands / @UPS, fijn dat jullie morgen langskomen voor de (1e) bezorging, maar ik ben er niet, en blijkbaar (na error op website en call naar de klantenservice) kan ik de aflevering alleen wijzigen nadat jullie voor een dichte deur hebben gestaan. Niet zo handig

I love my work :-). (translation in short: I pinpointed an issue in 10 minutes, where 5 others could not find the issue in 4 weeks)

So thrilled that Radia Perlman will be presenting at Sharkfest'23 US (#sf23us). And definitely looking forward to meeting her in San Diego!.
Radia Perlman will be at #sf23us to present a keynote!. She was 1 of very few women involved in building the networks & technology that became the internet. She invented the Spanning Tree Protocol algorithm & is often called the “Mother of the Internet.".

Yay, after 3 years we finally have the second Wireshark Users NL meetup. ~40 #wireshark enthousiasts showed up to listen to my update on the Wireshark foundation and new features. And to Stans talk on how to use Wireshark in red teaming.
