Hi,
In the BPF - Berkeley Packet Filter, when a file descriptor is associated to an interface to send and receive packets, there is an ioctl parameter "BIOCSSEESENT", which is by default set to 1. Hence the packets both from "remote systems" and "locally generated" are received.
If "locally generated" packets needs to be filtered, we can use the option "BIOCSSEESENT" and set the value to 0.
But even after setting this value to 0 (using the ioctl call), the "locally generated" packets are received.
Am I missing something ? Plese throw light on this issue.
TIA
Raj
