Depends on used interpreter and system, see examples below. Any python-can interface can be provided. Please see: https://python-can.readthedocs.io for further interface examples. optional arguments: -a, --python-can_args Additional arguments for a python-can Bus object. -h, --help show this help message and exit -n NOISE_LISTEN_TIME, --noise_listen_time NOISE_LISTEN_TIME Seconds listening for noise before scan. -t SNIFF_TIME, --sniff_time SNIFF_TIME Duration in milliseconds a sniff is waiting for a flow-control response. -x, --extended Scan with ISOTP extended addressing. This has nothing to do with extended CAN identifiers -C, --piso Print 'Copy&Paste'-ready ISOTPSockets. -v, --verbose Display information during scan. --extended_can_id Use extended CAN identifiers Example of use: Python2 or Windows: python2 -m scapy.tools.automotive.isotpscanner --interface=pcan --channel=PCAN_USBBUS1 --start 0 --end 100 python2 -m scapy.tools.automotive.isotpscanner --interface=pcan --channel=PCAN_USBBUS1 -a 'bitrate=500000 fd=True' --start 0 --end 100 python2 -m scapy.tools.automotive.isotpscanner --interface vector --channel 0 --start 0 --end 100 python2 -m scapy.tools.automotive.isotpscanner --interface vector --channel 0 --python-can_args 'bitrate=500000, poll_interval=1' --start 0 --end 100 python2 -m scapy.tools.automotive.isotpscanner --interface socketcan --channel=can0 --start 0 --end 100 Python3 on Linux: python3 -m scapy.tools.automotive.isotpscanner --channel can0 --start 0 --end 100 file)printsysstderrstdout)Zis_errorrZ/var/www/html/gsl.tools/lib/python3.9/site-packages/scapy/tools/automotive/isotpscanner.pyusages&rcCstrj|rPd|||f}tddddtd|DD}tf||d|}q|d||f}t||d}nt|d}d |}||fS) Nz)CANSocket(bustype='%s', channel='%s', %s)css|]\}}|t|fVqdS)Nr).0kvrrr Pz create_socket..css|]}|dVqdS)=N)split)rpairrrrrQrz, | |,)Zbustypechannelz%CANSocket(bustype='%s', channel='%s'))rz"%s")r dictrerr )python_can_args interfacerinterface_stringZarg_dictsockrrr create_socketHs(   r%c sd}d}d}d}d}d}d}d}d}d} d} dt_ttjdddgd} z| dD]\} } | d vrnd }qX| d vr|d }qX| d vrd }qX| d vrtdtdqX| dvrt| }qX| dvrt| }qX| dvr| } qX| dvr| }qX| dvr| } qX| dvr t| d}qX| dvr t| d}qX| dvrXd }qXWnDtjyt}z(td t d|tj dt WYd}~n d}~00|dus|dus|dust r| durtd t dtj dtd|dks|dkrt dt dtj dtd|s*|dks|dkr*t dtj dtd||krLt dtj dtdzzt| | |\}}|rt dt |t |ftfd d!}ttj|ttj|t|t||d||t|d"|rd#nd$|||d% }t d&|WnTtyJ}z:td t d'tj dt |tj dtdWYd}~n d}~00W|dur|js|n|dur|js|0dS)(NFdzvxCt:n:i:c:a:s:e:h:w) verboseznoise_listen_time=z sniff_time=z interface=pisozchannel=zpython-can_args=zstart=zend=helpextendedextended_can_idr)z-vz --verboseT)z-xz --extended)z-Cz--piso)z-hz--help)z-tz --sniff_time)z-nz--noise_listen_time)z-iz --interface)z-cz --channel)z-az--python-can_args)z-sz--start)z-ez--endz--extended_can_idzERROR:r z( Please provide all required arguments. i z%Argument 'start' and 'end' must be < izmStandard can identifiers must be < 0x800.
