Webs = socket.socket (socket.AF_INET, socket.SOCK_RAW, socket.IPPROTO_RAW) socket.IPPROTO_RAW gives you access to Level 3 protocol (IP), whereas ethernet is on Level 1 and 2. At level 3 an ethernet frame is already analyzed and its headers discarded. You need to get to Level 2 and ETH_P_ALL protocol seems to be a nice place to start.
