I am starting to work on a lightweight OSPFv2 protocol implementation and thought that twisted looked like a good tool to use for a lot of the state machine and timing parts. I need to create a SOCK_RAW socket for protocol 89. Can someone point me in the right direction to get twisted to use this? Here's a minimal example of what I need to do to receive the packets import socket import struct sock = socket.socket(socket.AF_INET, socket.SOCK_RAW, 89) sock.bind(('', 0)) multicast_group = '224.0.0.5' group = socket.inet_aton(multicast_group) mreq = struct.pack('4s4s', group, socket.inet_aton('192.168.88.253')) sock.setsockopt(socket.IPPROTO_IP, socket.IP_ADD_MEMBERSHIP, mreq) while True: data, address = sock.recvfrom(1024) print(data.hex())
