=head1 DESCRIPTION

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

=head1 OPTIONS

=over 4

=item --help

Print program arguments.

=item --version

Print program version.

=item --extcap-interfaces

List available interfaces.

=item --extcap-interface=E<lt>interfaceE<gt>

Use specified interfaces.

=item --extcap-dlts

List DLTs of specified interface.

=item --extcap-config

List configuration options of specified interface.

=item --capture

Start capturing from specified interface save saved it in place specified by --fifo.

=item --fifo=E<lt>path to file or pipeE<gt>

Save captured packet to file or send it through pipe.

=item --maxbytes=E<lt>bytesE<gt>

Set the max number of bytes per packet.

=item --count=E<lt>numE<gt>

Number of packets to generate (-1 for infinite).

=item --delay=E<lt>msE<gt>

Wait a number of milliseconds after writing each packet.

=item --random-type

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

=item --all-random

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

=item --type=E<lt>packet typeE<gt>

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

  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}

To capture:

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

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