How to find the MAC address of the Omega Onion

Jeremy Jones

Is there a way to find the MAC address during initial setup?

If you run ifconfig, you should see the following:

root@Omega-172C:/# ifconfig
lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:65536  Metric:1
          RX packets:92 errors:0 dropped:0 overruns:0 frame:0
          TX packets:92 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:7869 (7.6 KiB)  TX bytes:7869 (7.6 KiB)

wlan0     Link encap:Ethernet  HWaddr AA:BB:CC:DD:EE:FF
          inet addr:192.168.1.101  Bcast:192.168.1.255  Mask:255.255.255.0
          inet6 addr: fe80::42a3:6bff:fec1:172d/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:40040 errors:0 dropped:0 overruns:0 frame:0
          TX packets:29579 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:6274033 (5.9 MiB)  TX bytes:29299497 (27.9 MiB)

MAC Address is HWaddr that you see there

Just out of interest did you get a block of OUI's for use with the Omega? If so then tell the guys over at nmap cause atm not showing up as known

We have an MA-M assignment form IEEE starting with 40-A3-6B.
You can look it up at https://regauth.standards.ieee.org/standards-ra-web/pub/view.html#registries and search for "Onion".

I think that it is weird that in the web console under "status" the MAC address of the router is shown. I would expect there the MAC address of the Omega Onion.

@Rinus-van-Weert Good point. We can show both.

The MAC on my Onion2+ begins with 42:a3:6b:00 instead of 40:a3:6b:c0 as on both the box and device stickers.
