QUESTION
We are trying to communicate with Renault Zoe according to DIN SPEC 70121.
We are successfully communciating with the Hyundai Kona and BMW i3 but fail to receive the SPD Request with Renault Zoe. We are passing the SLAC process with Renault Zoe but we don't recieve any UDP messages afterwards. We are sending the CM_SLAC_MATCH_CNF message as an ethernet unicast message according to DIN SPEC 70121:2014-12, 8.3.3.3.2, Table 2 (noted in Design Guide Combined Charging System V5 - Failures during SLAC - Interruption at SLAC match sequence).
Why can it be that we receive the SDP Request with Kona and i3 but fail to do so with Zoe? Has anyone experienced this behaviour before?
Sniffed SLAC messages with scapy:
(= '' means the field is filled with zeroes)
Received from Zoe:
...ANSWER
Answered 2022-Feb-25 at 12:01The solution was to send the 2 byte field MatchVariableFieldLen in the CM_SLAC_MATCH_CNF message in little-endian byte order.
From the message that was send by the Renault Zoe, we can see that Zoe sends the CM_SLAC_MATCH_REQ with the MatchVariableFieldLen as 0x3e 0x00 (15872 == 0x3e00). Since this field should be 0x3e according to DIN SPEC 2014-12, we can see the byte order of this field is little-endian. So a reasonable guess was that it expects this field in little-endian in the response message.
Result: We received the SDP request and the messages after that.
The HomePlug GP Specification does not specify the endianness of this field in clause 11.5.58. But looking at the example in Table 11-316, one would say its big-endian.
It's clear that Zoe interpret this field as little-endian and doesn't accept 0x00 0x56 but accepts 0x56 0x00.
Kona and i3 either don't complain about this field and accept the message or Zoe's intepreting is false. Either way the cause of the problem has been identified.
QUESTION
So I've made a python program that creates a fake access point by sending lots of beacon frames using Scapy. The program works fine, but i wanted to expand it. I want the program to be able to make multiple fake access points. I tried simple threading but that didn't work out. I tried running the program on 3 different terminals and give each terminal another SSID. That worked fine, but i want my code to do that.
Here's my code:

How would I get the IP addresses of all ips connected to wifi (that I am on). I tried doing it by using sniff() and getting all src IP of those packets using the following lines:
...ANSWER
Answered 2022-Jan-05 at 03:18Forgive me if I'm misunderstanding your question.. what you're trying to do is map all live hosts on your LAN?
A simpler approach is to use the builtin ipaddress and socket libraries. For each IP in your LAN subnet, try connecting a socket to various ports (TCP/UDP). If a connection is established, a host exists at that IP.
Here's some code I can think of that might solve your problem (I have not tested this myself)

QUESTION
Currently trying to make handshake process on python using raw sockets but for some reason I can't send any packet with TCP protocol receiving OSError: [WinError 10022] An invalid argument was supplied. Here is my code:
...ANSWER
Answered 2021-Dec-10 at 16:53I found out what is wrong. Windows doesn't allow to send TCP packets with raw sockets so this code will never work. Probably it is possible to write the same with scapy or using other libraries but that's not what I need so the only way to make it work is to run on linux. Still not sure if the packet creation is correct but TCP protocol with raw sockets sure works fine on linux.

Answered 2021-Nov-11 at 07:31To access the port values in TCP layer you can use sport and dport.
So you can adjust your code like this:

I have a project in which I am building a DNS Forwarder.
I am using a UDP Server socket to listen to the DNS requests on port 53 (client is using the dig command) and I have to forward the received raw DNS request to scapy for dissecting it. I know that scapy is used to forge/send/manipulate packets.
The raw request looks something like this -

Vulnerabilities
Install scapy
You can use scapy like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
