Diagnose my Python/Scapy errors anyone? - Derby - 28-08-2013
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:

AttributeError: 'str' object has no attribute 'sort'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.
