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.
