I’ve used Ethereal for years on hundreds of PCs. Never had a problem, aside from a little BPF parsing weirdness in the early days of WinPcap.

 

But now I’ve got a machine that won’t see promisc traffic on one of its 2 interfaces. It has an Intel Pro/100+ Server Adapter and a cheapo RealTek 10/100. The Intel only sees its own traffic, even though it is plugged into a mirrored switch port. A notebook computer plugged into the same port sees it all.

 

I assume this means WinPcap is having trouble setting the NIC register to put the card in promisc mode, or some such? I dunno, I’ve tried removing all vestiges of WinPcap and Ethereal, rebooting and reinstalling. I’ve tried uninstalling the NIC driver and letting Win2000 re-detect it. No joy.

 

What am I missing?
