NAME

randpktdump - Provide an interface to generate random captures using randpkt

SYNOPSIS

randpktdump [ --help ] [ --version ] [ --extcap-interfaces ] [ --extcap-dlts ] [ --extcap-interface=<interface> ] [ --extcap-config ] [ --capture ] [ --fifo=<path to file or pipe> ] [ --maxbytes=<bytes> ] [ --random-type=<true|false> ] [ --all-random=<true|false> ] [ --type=<packet type> ]

DESCRIPTION

randpktdump is a extcap tool that provides access to the random packet generator (randpkt). It is mainly used for testing and educational purpose.

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 save saved it in place specified by --fifo.

--fifo=<path to file or pipe>

Save captured packet to file or send it through pipe.

--maxbytes=<bytes>

Set the max number of bytes per packet.

--random-type

Choose a random packet type for all packets if set to true.

--all-random

Choose a different random packet type for each packet if set to true.

--type=<packet type>

Use the selected packet type. To list all the available packet type, run randpktdump --help.

EXAMPLES

To see program arguments:

    randpktdump --help

To see program version:

    randpktdump --version

To see interfaces:

    randpktdump --extcap-interfaces

  Example output:
    interface {value=randpkt}{display=Random packet generator}

To see interface DLTs:

    randpktdump --extcap-interface=randpkt --extcap-dlts

  Example output:
    dlt {number=1}{name=randpkt}{display=Ethernet}

To see interface configuration options:

    randpktdump --extcap-interface=randpkt --extcap-config

  Example output:
    arg {number=0}{call=--maxbytes}{display=Max bytes in a packet}{type=unsigned}{range=1,5000}{default=5000}{tooltip=The max number of bytes in a packet}
    arg {number=1}{call=--count}{display=Number of packets}{type=long}{default=1000}{tooltip=Number of packets to generate (-1 for infinite)}
    arg {number=2}{call=--random-type}{display=Random type}{type=boolean}{default=false}{tooltip=The packets type is randomly choosen}
    arg {number=3}{call=--all-random}{display=All random packets}{type=boolean}{default=false}{tooltip=Packet type for each packet is randomly choosen}
    arg {number=4}{call=--type}{display=Type of packet}{type=selector}{tooltip=Type of packet to generate}
    value {arg=4}{value=arp}{display=Address Resolution Protocol}
    [...]
    value {arg=4}{value=usb-linux}{display=Universal Serial Bus with Linux specific header}

To capture:

    randpktdump --extcap-interface=randpkt --fifo=/tmp/randpkt.pcapng --capture

To stop capturing CTRL+C/kill/terminate application.
