SocketCAN userspace utilities and tools

This repository contains some userspace utilities for Linux CAN subsystem (aka SocketCAN):

Basic tools to display, record, generate and replay CAN traffic

• candump : display, filter and log CAN data to files
• canplayer : replay CAN logfiles
• cansend : send a single frame
• cangen : generate (random) CAN traffic
• cansniffer : display CAN data content differences

CAN access via IP sockets

• 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-kernel gateway configuration

• cangw : CAN gateway userpace tool for netlink configuration

CAN bus measurement and testing

• canbusload : calculate and display the CAN busload
• can-calc-bit-timing : userspace version of in-kernel bitrate calculation
• canfdtest : Full-duplex test program (DUT and host part)

ISO-TP tools ISO15765-2:2016 for Linux

• isotpsend : send a single ISO-TP PDU
• isotprecv : receive ISO-TP PDU(s)
• isotpsniffer : 'wiretap' ISO-TP PDU(s)
• isotpdump : 'wiretap' and interpret CAN messages (CAN_RAW)
• isotpserver : IP server for simple TCP/IP <-> ISO 15765-2 bridging (ASCII HEX)
• isotpperf : ISO15765-2 protocol performance visualisation
• isotptun : create a bi-directional IP tunnel on CAN via ISO-TP

Log file converters

• asc2log : convert ASC logfile to compact CAN frame logfile
• log2asc : convert compact CAN frame logfile to ASC logfile
• log2long : convert compact CAN frame representation into user readable

Serial Line Discipline configuration (for slcan driver)

• slcan_attach : userspace tool for serial line CAN interface configuration
• slcand : daemon for serial line CAN interface configuration
• slcanpty : creates a pty for applications using the slcan ASCII protocol
