    Promiscuous mode / TCP dump

    b_jackson

      My question is, does Galileo support promiscuous mode on wlan0?

       

      I am trying to use TCP dump to look at all packets on a wireless network, including traffic between other devices.   However, I am only able to see packets to or from my device, and broadcast packets. 

       

      I have put wlan0 in promiscuous mode on the Galileo I am running TCP dump on.  Here is the the ifconfig output:

       

      wlan0      Link encap:Ethernet  HWaddr: 0C:D2:92:D2:DC:48

                     inet addr:192.168.2.1  Bcast:0.0.0.0  Mask:255.255.0.0

                     inet6 addr: fe80::ed2:92ff:fed2:dc46/64 Scope:Link

                     UP BROADCAST RUNNING PROMISC MULTICAST  MTU:1500  Metric:1

                     RX packets:0 errors:0 dropped:0 overruns:0 frame:0

                     TX packets:26 errors:0 dropped:0 overruns:0 carrier:0

                     collisions:0 txqueuelen:1000

                     RX bytes:0 (0.0 B)  TX bytes:4862 (4.7 KiB)

       

      The only reason I can think of for why I am not seeing any packets between other devices is because Galileo doesn't support promiscuous mode. However, "UP BROADCAST RUNNING PROMISC MULTICAST" suggests that it does.  Any help would be appreciated.
