Hello,
I trying to use packet lib to extract the ipv4 source address from arp and
ip4 packets, but I get the following error: AttributeError: 'NoneType'
object has no attribute 'src'. Any advice?
pkt = packet.Packet(array.array('B', msg.data))
eth_pkt = pkt.get_protocol(ethernet.ethernet)
arp_pkt = pkt.get_protocol(arp.arp)
ip4_pkt = pkt.get_protocol(ipv4.ipv4)
if arp_pkt:
pak = arp_pkt
elif ip4_pkt:
pak = ip4_pkt
else:
pak = eth_pkt
mac_src = eth_pkt.src
mac_dst = eth_pkt.dst
#arp_src = arp_pkt.src_ip
ip4_src = ip4_pkt.src
thank you.
