kandi X-RAY | scapy Summary

scapy is a Python library typically used in Tutorial, Learning applications. scapy has no bugs, it has no vulnerabilities, it has build file available, it has a Strong Copyleft License and it has high support. You can install using 'pip install scapy' or download it from GitHub, PyPI.
Scapy is a powerful Python-based interactive packet manipulation program and library. It is able to forge or decode packets of a wide number of protocols, send them on the wire, capture them, store or read them using pcap files, match requests and replies, and much more. It is designed to allow fast packet prototyping by using default values that work. It can easily handle most classical tasks like scanning, tracerouting, probing, unit tests, attacks or network discovery (it can replace hping, 85% of nmap, arpspoof, arp-sk, arping, tcpdump, wireshark, p0f, etc.). It also performs very well at a lot of other specific tasks that most other tools can't handle, like sending invalid frames, injecting your own 802.11 frames, combining techniques (VLAN hopping+ARP cache poisoning, VoIP decoding on WEP protected channel, ...), etc. Scapy supports Python 2.7 and Python 3 (3.4 to 3.9). It's intended to be cross platform, and runs on many different platforms (Linux, OSX, *BSD, and Windows).

                      QUESTION

                      Renault Zoe doesn't send SDP Request After SLAC Matching Process

                      Asked 2022-Feb-25 at 12:01

                      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:

                      ###[ CM_SLAC_MATCH_REQ ]###
                        ApplicationType= 0

                         |  RSVD      = ''
                      

                      Send to Zoe:

                      ###[ CM_SLAC_MATCH_CNF ]###
                        ApplicationType= 0

                      The 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.
