Hi all,
This a follow-up to an old thread, in case anyone runs into a similar
problem.
I can see the data coming in from the roach via the 10gbe using Tcpdump
and Wireshark with the correct IP address and port, but I never was able
to get data using this Python socket. Still puzzled. However, I returned
to this problem recently, and managed to get data using a raw socket with
the following Python code:
from socket import *
s = socket(AF_PACKET, SOCK_RAW, htons(3))
s.setsockopt(SOL_SOCKET, SO_RCVBUF, 2**30)
s.bind(('eth1', 3)
# my packet is 4096 B
data = s.recv(4138)
This gives you the data packet as well as the 42 byte packet header.
