DCE-ns3 : ioctl operation for wifiNetdevice

[Mohammad Abu Shattal]

Hi all,

I'm trying to sniff packets over Wifi DCE-ns3 nodes online "while packets are transmitted".I did that since I need to investigate traffic before it written to .pcap files.  I compiled sniffer.c and tested it for my Linux machine. it works fine when I tried to run it over DCE it compiles well but I received the following error messages in the code below and appended to it: File exists

I obtained the name of the wifinet device in ns3:
ns3::WifiNetDevice

if (ioctl (raw_socket, SIOCGIFFLAGS, &ifr) == -1)
{
    perror ("Error: Could not retrieve the flags from the device.\n");
    exit (1);
}

ifr.ifr_flags |= IFF_PROMISC;
if (ioctl (raw_socket, SIOCSIFFLAGS, &ifr) == -1)
{
    perror ("Error: Could not set flag IFF_PROMISC");
    exit (1);
}

This happens due to the ioctl operation I run on devices in order to put it in promisc mode. Does DCE support ioctl operations in ns3 wifi net devices?
Can I set WifiNet devices in promisc mode using C program run on top of DCE.
I'm scripting ns3 in Python. Is it Ok to run python script to set promisc mode on top of DCE?
I investigated node.RegisterProtocolhandler to set ns3 node to promisc mode but couldn't find a way to call it correctly in python.

If this operations are not supported is there any alternative to access packets in promisc mode online for wifi nodes.


thanks ......
