I am doing some academic work investigating IPv6 and was using Debian to craft packets with Scapy and send them, I had gotten as far as sending basic packets when the partition failed and I decided to move to Kali now rather than after my thesis.
Whether I run a Python script with the code or directly input it while using Scapy I get the same errors to which I can't find a documented solution anywhere and I've been searching for two days.
The code which won't execute is basic and as follows:
import logging
import sys
from scapy.all import *
conf.iface='eth0'
conf.route6.add(dst="fe80::60c:ceff:fee2:d4fe", gw="fe80::21f:c6ff:fe5d:8a38")
print conf.route6
i=IPv6()
i.dst="fe80::60c:ceff:fee2:d4fe"
i.src="fe80::21f:c6ff:fe5d:8a38"
i.display()
q=ICMPv6EchoRequest(data = "lol")
q.display()
p=(i/q)
reply=sr1(p)
reply.show()
The output and errors I'm receiving are as follows:

I am running rather late on the thesis the Scapy code implementation will be for (I have a week to implement, document, evaluate and conclude) so if ANYONE has suggestions as to how to remedy this I will be eternally grateful.
If anymore information is needed I'll be happy to provide.
Thanks,
Lux
