Hi folks.

I need to write a user program that  reads all ip packets on the 
local LAN.  I think I can do this using NIT (network Interface Tap)
but since this code is ultimately going to run on a MVME-147 board
running VxWorks, I'd like to do this with raw sockets since I know
they support sockets.

My question is, can raw sockets be used to read all packets ?
Will the IP layer pass things to the socket even though the packet
might not be addressed to the socket, or to the machine itself ( I 
intend to use the "promisc mode").

    I'd appreciate any help with this.

       thanks
