genmac-random

Generate a random MAC address

Syntax:

genmac-random [-m][-p]

Runs on:

QNX Neutrino

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.

Examples:

Generate and assign a random address to the mac option of the io-pkt-v6-hc:
sh -c "io-pkt-v6-hc -drgbe mac=`genmac-random -m`,
   -ptcpip pkt_typed_mem=below4G"
Generate MAC addresses for more than two interfaces on the same target, where the first time genmac-random is run, it's for the first interface and the second time it's run, a MAC address is generated for the second interface:
mac=`genmac-random -m` mac2=`genmac-random -m -p`
