I'm using linux-wireless snapshot from December, 2010 with the following driver: rt2800usb The linux-wireless snapshot for ath9k is from last summer ( July) As an example I'm building a program based on: http://wireless.kernel.org/en/users/Documentation/packetspammer Steps to test: ( Sender Host A rt2800usb: usbid: Bus 001 Device 002: ID 148f:3070 Ralink Technology, Corp. ) 1.) sudo iw phy phy0 interface add moni0 type monitor 2.) sudo iw dev moni0 set channel 11 3.) run packet injector via: pcap_inject() 4.) run tcpdump on moni0 and observe injected packet ( Receiver Host B: 04:02.0 Network controller: Atheros Communications Inc. AR5008 Wireless Network Adapter (rev 01)) 1.) sudo iw phy phy0 interface add moni0 type monitor 2.) sudo iw dev moni0 set channel 11 4.) run tcpdump on moni0 injected packet NOT received. Sanity test1: When I send a packet from A to B, packet is observed on moni0 Sanity test2: ran standalone packetspammer with no modifications with the same result. Question: Is this operation supported on these two devices? If not, what device can you recommend a device where this does work? regards, Andy -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
