Hi !
I saw PF_PACKET parameter for system call "socket" in linux. In FreeBSD
thare is PF_LINK (see <sys/sockst.h>).
I tried to execute this program:
#include <sys/types.h>
#include <sys/socket.h>
#include <iostream.h>
#include <errno.h>
main(){
cout << socket(AF_LINK, SOCK_RAW, 0)<<endl;
cout<<errno<<endl;
}
As a result errno == 43. I use 2.2.5 and hope that in latest versions of
FreeBSD I'll find direct access to Ethernet packets via
socket & recvfrom & sendto system calls.
