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.
