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?
Does that card support promiscuous mode? Is there any setting
preventing it from working in promiscuous mode
