I would like to figure out the MAC Address of the Ethernet and the Wireless Interfaces on my laptop. I have used the below commands with the following outputs.

$ ifconfig -a | grep HWaddr
eth0      Link encap:Ethernet  HWaddr 38:59:f9:10:12:13
$ ifconfig -a
eth0      Link encap:Ethernet  HWaddr 38:59:f9:10:12:13  
          inet addr:  Bcast:  Mask:
          inet6 addr: fe80::3a59:f9ff:fe10:1213/64 Scope:Link

          RX bytes:30782 (30.7 KB)  TX bytes:20338 (20.3 KB)

lo        Link encap:Local Loopback  
          inet addr:  Mask:
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1

          TX packets:29 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:2226 (2.2 KB)  TX bytes:2226 (2.2 KB)

I am currently connected using my wireless connection and I also have an ethernet port that I don't use. The above commands only provide me the MAC Address of the wireless connection. Is there a way to get the MAC Address of the ethernet connection without actually being connected through the ethernet LAN port?

Any pointers will be much appreciated.

Thanks in advance,
