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.

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
