Had trouble with my Debian partition so thought it would be best to make the inevitable change to Kali (I know, no one will think this is a good idea but I mainly use Linux for pen testing anyway)

Anyway, I am attempting IPv6 packets on Scapy with a very basic script so far it gives the same error if I run through the commands in the Scapy interface as if I run the Python code.

The code I get is as follows:

Code:
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 errors I get are as follows:

Code:

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

These errors have been fixed.

However, the code now fails often with a time out which I'm guessing is ICMPv6 rate limiting.

If anyone could hazard a better guess as to the problem or knows how to disable rate limiting on any OS it would be helpful!

If you are on Linux you might want to take a look at /proc/sys/net/ipv6/ .

One target OS and the source is Linux, will have a little look at that, thanks!

I'm sorry in my haste to push forward I hadn't mentioned here that the issue was using WLAN and through using ethernet I've managed to fixed the issue of not getting responses.
