Promicuous Mode for 3COM Ethernet or NIC and Linksys Wireless NIC

NTDEV

Hi,

I used passthru sample to intercept the set OID of
OID_GEN_CURRENT_PACKET_FILTER and use “*(ULONG *)info
|= NDIS_PACKET_TYPE_PROMISCUOUS;” to set the NICs to
promiscuous mode. The set returns success. However, I
could not see all packets. But my sniffer
program “ethereal” shows all packets that come into the
3COM NIC. I couldn’t see “other” direct packets from the
Linksys NIC. My driver is running in Windows 2000
Professional.

My questions are: can I set promiscuous mode in filter
driver? And does Linksys NIC support promicuous mode?

Thanks,
Minfeng Li

Hi,

I got the answer for the first question. I didn’t check
the ReceivePacketHandler where most packets coming from
the 3COM NIC.

I’m still try to find the answer for Linksys Wireless
NIC. Its W2k driver is a NDIS3 driver that only
indicates packet through ReceiveHandler.

Thanks,
Minfeng Li

For wireless, try NDIS packet filter of NDIS_PACKET_TYPE_ALL_LOCAL for
wireless...

Good luck,
