Can-Utils veya SocketCAN
The most common protocol now used in cars, controller Area Network or CAN basics, we can now proceed to setup can-utils. Can-Utils A set of Linux-specific utilities that allow Linux to communicate with the CAN network in the vehicle. In this way, the car can spoof and sniff attacks and our own CAN packages.
What is Can-Utils?
CAN is a message-based network protocol designed for vehicles.
Step 1: installing can- utils.
Kali or other Debian based repositories,
apt-get install can-utils
You can download and install it.
Basics of Can-Utils
CAN utilities are tools for working with in-vehicle CAN communications from the Linux operating system . These tools can be divided into several functional groups;
- Essential tools for viewing, recording, generating and replaying CAN traffic
candump: Displays, filters and saves CAN data to files.
canplayer: Replay CAN log files.
cansend: send a single frame.
cangen: (random) Generate CAN traffic.
cansniffer: Displays CAN data content differences (11-bit CAN IDs only).
- Access via IP sockets with Can
canlogserver: log CAN frames from a remote/local host.
bcmserver: interactive BCM configuration (remote/local).
socketcand: Use RAW/BCM/ISO-TP sockets via TCP/IP sockets.
- CAN in-core gateway configuration
cangw: CAN gateway userspace tool for
netlink configuration.
- CAN bus measurement and testing
canbusload: Calculates and displays the CAN bus load.
can-calc-bit-timing: userspace version of in-core bitrate calculation.
canfdtest: Full duplex test program (DUT and host part).
- ISO-TP tools for Linux ISO15765-2:2016
İsotpsend: send a single ISO-TP PDU.
isotprecv: Get ISO-TP PDUs.
isotpsniffer: ‘listen’ ISO-TP PDU( s ).
isotpdump: ‘listening’ and interpreting CAN messages (CAN_RAW).
isotpserver: IP server for simple TCP/IP ISO 15765-2 bridging (ASCII HEX).
isotpperf: ISO15765-2 protocol performance visualization.
isotptun: Create a bidirectional IP tunnel over CAN via ISO-TP.
- Log file converters
asc2log: Convert ASC log file to compact CAN frame log file.
log2asc: convert compact CAN frame log file to ASC log file.
log2long: convert compact CAN frame representation to user readable.
- Serial Line Discipline configuration ( for slcan driver)
slcan_attach: user area tool for serial line CAN interface configuration.
slcand: daemon for serial line CAN interface configuration.
slcanpty: slcan creates a pty for applications using the ASCII protocol.
Various hardware devices can be connected to the CAN network. If you cannot or will not purchase one of these hardware devices, you can always set up a virtual CAN network.
Setting up a Virtual CAN Network
vcan first (virtual CAN) install the module;
kali> modprobe vcan
Then set up your virtual interface;
kali> ip link add dev can0 type vcan
kali > ip link set up vcan0
We are now ready to start working with CAN communication. Now we just need to connect our Linux operating system to the vehicle. There are numerous devices, tools, and connection types to do this.
