Enrico,
You could use a bpf socket in order to send packets, as well as to
receive packets. However, I don't have a sample of the use of a bpf
sample for sending packets. The only sample which I have demonstrates
how to receive packets.

I see what you are taking about, but i understand (by my search on
google) that there is a method to build and send an arp packet + eth
header with bpf is it possible ?
thx

I must send a packet ( eth header, and arp packet ) over the en0.
In linux i use the sockaddr_ll struct and a PF_Packet. Now in bsd
i don't know how do it ,
can someone help me ?
thx,bye
Enrico,
For this, you want to open a PF_NDRV socket to send out a raw
ethernet packet. Take a look at the sample code BSDLLCTest
<http://developer.apple.com/samplecode/BSDLLCTest/BSDLLCTest.html>
This sample demonstrates the technique to open a PF_NDRV socket,
which requires root access, then demonstrates both the send and
receive of packets using this socket.
Sending raw packets is straightforward, but the sample is designed
to receive LLC Ethernet frames. You'll need to tweak the sample to
receive a phase I Ethernet frame for a tcp packet, if this is
within the scope of your project.
