[Winpcap-users] Windump problem - I don't see ANYTHING

[Gianluca Varenni]

Just a quick addendum to the wireless problem: it's not only a matter of 
(un)supported network cards (being them wireless or wired). It's also a 
matter of network card drivers. Some cards are supported (and by supported I 
mean that they work in promiscuous mode) with any version of their drivers, 
some others work only with some particular versions of their drivers (and 
maybe on some Windows flavors, only).

Back to your problem, I would try to capture in non-promiscuous mode 
("windump -p") and see what happens. If you capture packets, your wireless 
network card probably does not work in promiscuous mode...

Have a nice day

I thought I had looked and determined that my card was one of the supported
ones, but now I'm not so certain.  I guess there's lots of Orinoco cards out
there (?)

In response to your question, here is the output of windump -D on a 
Windows2K
box with my Orinoco plugged in.
(The Win2K is a very old box, I am using this now but usually don't use it 
when
I try to packet sniff; if the windump -D output would be different if I did 
it
under XP with the same card plugged in?)

c:> WinDump -D
1.\Device\NPF_GenericDialupAdapter (Generic dialup adapter)
2.\Device\NPF_{57B30D02-EED3-49AD-A49F-7C443C3B6661} (ORiNOCO 802.11bg
ComboCard Gold)
3.\Device\NPF_{282E40F1-2EBB-4A62-BA38-2A3CDCEB7ACA} (Intel(R) PRO Adapter)

I have another card that is usable, when I plug that one in also, the 
windump
-D output is (also on the Win2K box...)
c:\> windump -D
1.\Device\NPF_GenericDialupAdapter (Generic dialup adapter)
2.\Device\NPF_{26E4D579-E36A-49C1-903C-BABB091585CC} (IEEE 802.11 Wireless
LAN/PC Card(5V))
3.\Device\NPF_{57B30D02-EED3-49AD-A49F-7C443C3B6661} (ORiNOCO 802.11bg
ComboCard Gold)
4.\Device\NPF_{282E40F1-2EBB-4A62-BA38-2A3CDCEB7ACA} (Intel(R) PRO Adapter)

Can you tell the make/model/specifics of the card from this?
I was given the card as an add-on to another purchase, it doesn't have the
external antenna connector that the orinoco does, but if it's usable, by all
means I'll use it instead.

I hope you're right and I was just using an unsupported card. (?)
