Hi everybody,
I've recently been looking into raw socket programming. However there's still a question that remains. Maybe it's just a case of RTFM, if so point me to a good manual on the topic.
The man pages indicate that you can do read and write operations with rawsock aswell as bpf. However, in all of the source codes I found, a raw socket was used to write to, and bpf was used to read from the interface.

Search for "raw_tcp.tgz" in that page.
What's the advantage in using the rawsock bpf combination instead of
bpf (or raw socket) only?
Depends on what best fits your development circumstances.
The paper I co-authored uses bpf for reading, and socket for writing.
Thx in advance,
dave

Never ask a man what OS he uses. If it's FreeBSD, he'll tell you.
If it's not, why embarrass him? ..I'm sorry..
