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 application.
