genmac-random

QNX SDP8.0Utilities ReferenceUtilities

Generate a random MAC address

Syntax:

genmac-random [-m][-p]

Runs on:

QNX OS

Options:

-m: Print the MAC address.
-p: Toggle the lower bit of the generated MAC address. This permits the genmac-random utility to be on two interfaces on the same target.

Description:

The genmac-random generates a random MAC each time it's run to stdout using the random service and reading from /dev/random. If no options are provided, the MAC address is provided as an ID Number.

Note:

This utility uses the random service and must be able to read from /dev/random, otherwise it fails.
