Hi,<div><br></div><div>After tracing the source code, I found that in PacketSetHwFilter, you set the packet filter NDIS_PACKET_TYPE_PROMISCUOUS is true. Otherwise the packet filter is set to NDIS_PACKET_TYPE_ALL_LOCAL.</div>
<div><br></div><div>In the WDK documentation, it says:</div><div>It is only valid for the miniport driver to enable the
NDIS_PACKET_TYPE_PROMISCUOUS, NDIS_PACKET_TYPE_802_11_PROMISCUOUS_MGMT, or
NDIS_PACKET_TYPE_802_11_PROMISCUOUS_CTRL packet filters if the driver is
operating in Network Monitor (NetMon) mode.<br><br></div><div>But in the source code, I can't find any request to the driver that sets its operation mode to NetMon mode.</div><div><br></div><div>So I think setting promiscuous mode in WireShard will have to effect on the NIC if the NIC driver follows the WDK documentation.</div>
<div><br></div><div>Is that right?</div><div><br></div><div>Best regards, </div><div>Haich</div><div><br><div class="gmail_quote">On Tue, Sep 1, 2009 at 10:49 AM, yu-ruei woo <span dir="ltr"><<a href="mailto:haich.woo@gmail.com">haich.woo@gmail.com</a>></span> wrote:<br>
