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> ] [ --count=<num> ] [ --delay=<ms> ]
       [ --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.

       --count=<num>
           Number of packets to generate (-1 for infinite).

       --delay=<ms>
           Wait a number of milliseconds after writing each 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=--delay}{display=Packet delay (ms)}{type=long}{default=0}{tooltip=Milliseconds to wait after writing each packet}
           arg {number=3}{call=--random-type}{display=Random type}{type=boolflag}{default=false}{tooltip=The packets type is randomly chosen}
           arg {number=4}{call=--all-random}{display=All random packets}{type=boolflag}{default=false}{tooltip=Packet type for each packet is randomly chosen}
           arg {number=5}{call=--type}{display=Type of packet}{type=selector}{tooltip=Type of packet to generate}
           value {arg=5}{value=arp}{display=Address Resolution Protocol}
           [...]
           value {arg=5}{value=usb-linux}{display=Universal Serial Bus with Linux specific header}

       To capture:

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

           Note

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