socketcand

Socketcand is a daemon that provides access to CAN interfaces on a machine via a network interface. The communication protocol uses a TCP/IP connection and a specific protocol to transfer CAN frames and control commands. The protocol specification can be found in ./doc/protocol.md.

Installation

To build and run socketcand make sure you have the following tools installed:

First run

$ ./autogen.sh

to create the 'configure' script.

Then run the created script with

$ ./configure

to check your system and create the Makefile. If you want to install scripts for a init system other than SysVinit check the available settings with './configure -h'. To compile and install the socketcand run

$ make
$ make install

Service discovery

The daemon uses a simple UDP beacon mechanism for service discovery. A beacon containing the service name, type and address is sent to the broadcast address (port 42000) at minimum every 3 seconds. A client only has to listen for messages of this type to detect all SocketCAN daemons in the local network.

Usage

 socketcand [-v | --verbose] [-i interfaces | --interfaces interfaces]
	[-p port | --port port] [-l interface | --listen interface]
	[-u name | --afuxname name] [-n | --no-beacon] [-d | --daemon]
	[-h | --help]
