NAME

6       randpktdump - Provide an interface to generate random captures using
7       randpkt
8

SYNOPSIS

10       randpktdump [ --help ] [ --version ] [ --extcap-interfaces ]
11       [ --extcap-dlts ] [ --extcap-interface=<interface> ]
12       [ --extcap-config ] [ --capture ] [ --fifo=<path to file or pipe> ]
13       [ --maxbytes=<bytes> ] [ --count=<num> ] [ --delay=<ms> ]
14       [ --random-type=<true|false> ] [ --all-random=<true|false> ]
15       [ --type=<packet type> ]
16

DESCRIPTION

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