Then, run a packet trace on that interface. This will list all your network interfaces. Step one is figure out what network interface you want to dump. Tcpdump comes on OSX (or if it doesn’t, something installed it without me knowing!).

So I’m having trouble with connection times spiking to an Amazon Web Services ELB, so it’s time to break out the tcpdump to take packet traces and the wireshark (was ethereal long ago) to analyze it. Join Gerald Combs, Hansang Bae, Kary Rogers, Sake Blok, Jasper Bongertz, Christian Landström, Phill Shade, and many other packet analysis experts at SharkFest, an immersive Wireshark training experience.I’m going to start sharing little techie tidbits that require me to go scour the Internet for exactly how to do them, in hopes of making you able to do it in a lot less time than it took me!
