I'm at a complete road block here and I appreciate any help!
I'm trying to write a packet generator that generates a packet down to the destination/src mac address of an eth frame. However, nothing I find seems to explain how to do this let alone if it is possible. As example (for familiarity), implementing a RARP client (and server). I first create a socket:
socket(PF_INET, SOCK_PACKET, ETH_P_RARP)
After generating an entire packet (eth frame + RARP request) and sending it via sendto, tcpdump shows that my packet was encapsulated as the data for an IP packet. Definitely not what I want and I suspect it is because I'm passing the PF_INET domain (it assuming IP?).
So how would I go about implement sending a RARP request (obviously I'm doing something wrong or assuming something wrong)? Or more generally, how do I get pure raw socket access? --
