I'm trying to create a small PPPoE Access Concentrator to learn the inner workings of PPPoE. This requires me to send non-IP packets, I need to be able to set the ETHER_TYPE and eventualy the destination mac fields in the ethernet frame header, but as far as I can tell, raw WinSock sockets give me the ability to supply my own IP header, but not the ethernet header.

Is this true? And if so, is th开发者_Python百科ere any way of circumventing this?

I am well aware of WinPcap, and will use it ONLY as a last resort.

I believe that you are correct. Winsock will allow a raw IP socket but does not allow you to get beneath layer 3 and send non-IP packets. For this I believe you would need to pursue the WinPcap / TDI option . More information.
