Found an easier way to spoof the mac addresses which requires no changes to the firmware and is a simple script.
I call the scripts /etc/init.d/spoof0, spoof1 and spoof2
1 - nano /etc/init.d/spoof0
2 - script for LAN
#!/bin/sh /etc/rc.common
START=17
uci set network.lan.macaddr=aa:bb:cchexdump -n3 -e'3/1 ":%02x"' /dev/urandom
uci commit network
3 - change it to be executible
Here I tinker with much hardware at home. (close to 100 devices today).
I manage or look at the hardware via IP, names and custom mac addresses.
My touchscreen consoles are in the same set of IPs with matching numbered mac addresses arranged in groups of hardware / OS types. Guessing that is a bit OCD.
In the mix today there are a few SOHO routers of all types. I utilize PFSense today with multiple internet connections, multiple NICs/VLANs for internal connections some for day to day use and other networks just to play with.
Well too to become more familiar with OpenWRT. That is me though.
Is the mac address stored in other than the art partition? Did I edit the wrong file?
Is there a copy of the mtd3 partition being cached?
Yes edited the beginning of the art image with the Linux Bless Hex editor where I saw the mac address and wrote it back to the AR 300M.
Relating to the AR300M’s use as a travel router I have recommended it’s use to a peer who is purchasing it for himself / his parents.
Here also went to installing a competitor’s micro router inside of my Leviton OmniPro 2 alarm panel media cabinet. I chose this one based on it’s size as I have the security panel fully optioned out. The board is about 1/2 the size of the AR300M. It fits on one side between a stacked set of daughter boards and the side of the cabinet.
I use it to massage the network connectivity to the panel. It is powered by the panel such that in an event of a power outage it continues to work. Also talks serially to the panel. It can also serve as an out of band management device using a 3-4G cellular device. I happen to have a few of the automotive style 12VDC to 5VDC transformers around but switching over to a bucky style power supply for two 5VDC device use. (also using a GPS / PPS board for time sync off net). BTW and it’s been about a year ago had a mfg company over there design a board (on paper) a micro router as wide as a NIC with two NIC ports on it / USB / Serial and an RTC. It was the size of my index finger (with no antennas). Looked more like a dongle.
