NAME¶

dpauxmon - Provide interfaces to capture DisplayPort AUX channel data.

SYNOPSIS¶

dpauxmon [ --help ] [ --version ] [ --extcap-interfaces ] [ --extcap-dlts ] [ --extcap-interface=<interface> ] [ --extcap-config ] [ --extcap-capture-filter=<capture filter> ] [ --capture ] [ --fifo=<path to file or pipe> ] [ --interface_id=<Interface ID to capture> ]

dpauxmon --extcap-interfaces

dpauxmon --extcap-interface=<interface> --extcap-dlts

dpauxmon --extcap-interface=<interface> --extcap-config

dpauxmon --extcap-interface=<interface> --fifo=<path to file or pipe> --capture --interface_id=interface_id

DESCRIPTION¶

dpauxmon is an extcap tool that can capture DisplayPort AUX channel data from linux kernel drivers using the generic netlink interface.

Supported interfaces:

1. dpauxmon

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>

Save captured packet to file or send it through pipe.

--interface_idt=<interface id>

The interface for capture.

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.

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

To see interface DLTs:

    dpauxmon --extcap-interface=dpauxmon --extcap-dlts
  Output:
    dlt {number=275}{name=dpauxmon}{display=DisplayPort AUX channel monitor DLT}

To see interface configuration options:

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