My introduction to protocol analysis was lugging a Network General Sniffer™️ around a university. The Sniffer defined an entire industry, and a lack of one at a later job inspired me to create Wireshark. Its source code is now available at dpiconsortium.org/sniffer-prot....

In current versions of #Wireshark, if you want to save an external capture utility configuration you have to use a profile. I'm working on an interface bookmark feature which will decouple that and make it easier to save a bunch of extcap configurations.

I'm at #SharkFest this week and someone brought in a vintage protocol analyzer. As you can see, looking at network traffic used to require gear that was a) specialized and b) heavy.

Looking back I suspect that I got my start in networking because my manager didn't want to lug a heavyass Sniffer around our university campus so he handed the job off to the nearest twentysomething with a strong back.

I think we need an inverse thread where we talk about things that normal intelligent people universally agree upon that are for some reason hot takes within your profession

Periodic reminder that if even a little bit of your job involves looking at packets, you should show up at SharkFest.

I keep having to justify why I want to go to conferences outside the USA and the simple answer is "Many of the people it would be helpful to talk to are no longer able to enter the USA"

The changed code is a small fraction of an open source contribution. Your commitment to understand the issue, how your proposed solution fits with the project, and be ready to own and push the review process forward is the biggest chunk of the work. Your effort is the contribution, not the code.

Just want to take a moment and give the @wiresharkfoundation.org a shout-out for having AWESOME documentation. I absolutely love it when official docs include clear and concise explanations, including "hey here's this common issue, why it happens, and a few ways to work around it."

I don’t know if anyone else notices or cares, but when I see a presentation in which the speaker uses obviously generated-AI images to illustrate their slides, it makes me immediately less confident in whatever other content they’re presenting.
