No route detected for IPv6 packets in conjunction with scapy. #29

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Hello. 

I am currently using scapy with libdnet in order to send an IPv6 Packet to a  
random location. Problem is the packets are supposed to leave the machine but 
wireshark captures no packets leaving the pc. 

On closer inspection i realised that conf.route6 from scapy is empty. Then i 
tried to get all the interfaces from my device. Here is what i got back: 

{'flags': 33, 'link_addr': b0:90:20:52:41:53, 'type': 6, 'name': 'eth0', 'mtu': 
1500L}

As you can see, nowhere in there there is an ipv6 address. How am i supposed to 
send ipv6 packets if no ipv6 address is listed? in extend, here is the ipconfig 
from cmd:

Ethernet adapter Local Area Connection 4:

This is run on a VM but i dont think it matters. 
PLEASE someone help me this is very important! how can i configure scapy in 
order to understand how to send ipv6 packets. and why do i see no ipv6 
addresses in the list above?
