Supported interfaces:

Options

--help

Print program arguments.

--version

Print program version.

--extcap-interfaces

List available interfaces.

--extcap-interface=<interface>

Use specified interfaces.

--extcap-dlts

List DLTs of specified interface.

--extcap-config

List configuration options of specified interface.

--capture

Start capturing from specified interface and save it in place specified by --fifo.

--fifo=<path to file or pipe>

--interface_idt=<interface id>

Examples

To see program arguments:

dpauxmon --help

To see program version:

dpauxmon --version

To see interfaces:

dpauxmon --extcap-interfaces

Only one interface (dpauxmon) is supported.

Example output

interface {value=dpauxmon}{display=DisplayPort AUX channel capture}

To see interface DLTs:

dpauxmon --extcap-interface=dpauxmon --extcap-dlts

Example output

dlt {number=275}{name=dpauxmon}{display=DisplayPort AUX channel monitor DLT}

To see interface configuration options:

dpauxmon --extcap-interface=dpauxmon --extcap-config

Example output

dpauxmon --extcap-interface=dpauxmon --extcap-config
arg {number=0}{call=--interface_id}{display=Interface Id}
    {type=unsigned}{tooltip=The Interface Id}
    {required=true}

To capture:

dpauxmon --extcap-interface=dpauxmon --fifo=/tmp/dpauxmon.pcap --capture --interface_id 0
