SocketCAN is a collection of CAN drivers and networking tools for Linux. It allows interfacing with CAN bus devices in a similar fashion as other network devices. This allows for developers to write code that can support a variety of CAN bus interfaces, including CANtact. Unfortunately, SocketCAN only works on Linux.
Since Linux and Kernels ans such are still a bit advanced for me, i cant really find any decent / proper setup for can-utils and all these drivers that need to be setup. And with desperation ive tried to run pretty much all terminal commands ive come across in hope to get something to work (stupid i know, but desperation is overwhelming).

I've gotten quite far trying to compile can-utils on Mac OSX. I had to redefine typedefs and the location of socket.h for Mac OSX. I finally got stuck with the following error: bcmserver.c:234:8: error: no member named 'ifrifindex' in '. Besides brew install coreutils, you may also need to install some other packages, such as gnu-sed, grep: brew install findutils brew install gnu-indent brew install gnu-sed brew install gnutls brew install grep brew install gnu-tar brew install gawk.

The specifics of installing SocketCAN depend on which Linux distribution you are using.
Ubuntu & Debian
On Ubuntu, the required kernel modules are included, however you will need to install can-utils.
You may need to enable the relevant kernel modules. To do so, run:
To use CANtact with SocketCAN, you will need to run slcand. For example:
![Can utils for mac shortcut Can utils for mac shortcut](/uploads/1/3/4/7/134765371/210026106.png)
This command creates a new device called
can0
that is connected to the CANtact at /dev/ttyACM0
. It will open the device when starting (-o
), close the device when finished (-c
), and set the speed mode to 6 (-s6
).After running this command, you will need to enable the interface:
Virtual CAN devices, or vcan devices, can be used to simulate a CAN bus without any hardware. This is useful for simulation, testing, and bridging. It also lets you try out can-utils without having an actual CAN device.
To create a vcan device run:
NOTE: If you get the error RTNETLINK answers: Operation not supported, load the module with sudo modprobe vcan and try again.
Once the device is created, you can use it like any other CAN device. Just replace
can0
in the examples with vcan0
.Once a device is enabled, there are a number of utilities that can be used.
candump
candump displays messages on the bus in realtime. To show all traffic in real time on device can0, run:
The displayed messages can be filtered using a mask and identifier. Two filter types are available:
- [can_id]:[can_mask] matches when [received_can_id] & [can_mask] [can_id] & [mask]
- [can_id]~[can_mask] matches when [received_can_id] & [can_mask] != [can_id] & [mask]
Examples
Only show messages with ID 0x123 on vcan0:
Only show messages with ID 0x123 or ID 0x456 on vcan0:
cansend
cansend sends a single CAN frame onto the bus. You will have to specify a device, an identifier and data bytes to send. For example:
will send a message on interface
can0
with identifier 0x123
and data bytes [0x11, 0x22, 0x33, 0x44, 0x55, 0x66, 0x77, 0x88]
. Note that this tool always assumes values are given in hexadecimal.cangen
cangen can generate random CAN data, which can be useful for testing. For more information, run
cangen
for detailed usage information.cansniffer
cansniffer displays frames that are currently on the bus, but filters out frames with data that is not changing. This is very useful for reverse engineering CAN bus systems. For more information, run
cansniffer
for detailed usage information.The can-utils package contains tools for working with ISOTP. However, these tools require a kernel module which is not available in Ubuntu's repositories. Fortunately, it is easy to compile and install.
Get the kernel module and install it using the instructions in the can-isotp README. This will add ISOTP support to the kernel.
With the module installed, you can use the various utilities. You will need two CAN devices (or virtual CAN devices) to send and receive data. For example, in one terminal, run:
isotprecv -s456 -d123 can1
in another terminal, run:
echo 'de ad be ef de ad be ef aa bb cc dd' | isotpsend -s123 -d456 can0
This will transmit the bytes between the two devices. Note that isotp tools expect data as hexadecimal values in ASCII, separated by spaces.
Wireshark includes support for SocketCAN. If you have a SocketCAN device active (real or virtual), you can select it in Wireshark and view the frames being received in real time.
Wireshark has the following filters for CAN messages:
- can.id (frame arbitration identifier)
- can.len (frame data length)
- can.flags.err (frame error flag)
- can.flags.rtr (frame remote flag)
- can.flags.xtd (frame extended identifier flag)
Wireshark also has filters for the canopen protocol.
SocketCAN makes it simple to interface with a variety of CAN bus hardware. It leverages standard network sockets, which means it can be accessed from many different languages.
Python
SocketCAN is supported in Python versions 3.3+. The pyvit library provides access to SocketCAN. You can use pyvit for this purpose, or reuse the SocketCAN implementation implementation.
C
A C source code example is available on the SocketCAN Wikipedia page.
