How to find my MAC address on Linux?

The first way

For Linux, you can always use the universal way: the command line!

1. 1

   You can do so by executing one of these commands.

   $ ifconfig
   enp2s0f0  Link encap:Ethernet  HWaddr b8:88:e3:b0:f3:f0
             UP BROADCAST MULTICAST  MTU:1500  Metric:1
             RX packets:0 errors:0 dropped:0 overruns:0 frame:0
             TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
             collisions:0 txqueuelen:1000
             RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
             Interrupt:16
   
   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:1969 errors:0 dropped:0 overruns:0 frame:0
             TX packets:1969 errors:0 dropped:0 overruns:0 carrier:0
             collisions:0 txqueuelen:1000
             RX bytes:198134 (198.1 KB)  TX bytes:198134 (198.1 KB)
   
   wlp3s0    Link encap:Ethernet  HWaddr a4:17:31:79:1e:01
             inet addr:192.168.1.43  Bcast:192.168.1.255  Mask:255.255.255.0
             inet6 addr: fe80::4828:6227:27b9:2670/64 Scope:Link
             UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
             RX packets:111214 errors:0 dropped:0 overruns:0 frame:0
             TX packets:76742 errors:0 dropped:0 overruns:0 carrier:0
             collisions:0 txqueuelen:1000
             RX bytes:87608671 (87.6 MB)  TX bytes:13789254 (13.7 MB)
   
   $ ip address show
   1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
       link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
       inet 127.0.0.1/8 scope host lo
          valid_lft forever preferred_lft forever
       inet6 ::1/128 scope host
          valid_lft forever preferred_lft forever
   2: enp2s0f0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000
       link/ether b8:88:e3:b0:f3:f0 brd ff:ff:ff:ff:ff:ff
   3: wlp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
       link/ether a4:17:31:79:1e:01 brd ff:ff:ff:ff:ff:ff
       inet 192.168.1.43/24 brd 192.168.1.255 scope global dynamic wlp3s0
          valid_lft 21562sec preferred_lft 21562sec
       inet6 fe80::4828:6227:27b9:2670/64 scope link
          valid_lft forever preferred_lft forever

2. 2

   As you can see, there is a lot of output, but we are only interested in MAC addresses (They are underlined in red).

   

   These screenshots show that my computer has three network interfaces: lo - Local loopback, enp2s0f0 - my ehternet adapter and wlp3s0 - my Wi-Fi adapter.

The second way

If you are using Ubuntu 16.04, you can find your MAC addresses via GUI.

1. 1

   Open All Settings application and click on Network.

   
2. 2

   Select Wireless and choose the connection you have plugged in and click on the blue arrow.

   
3. 3

   Now you can see your MAC address.

   
4. 4

   You may not have an active connection, so you can try to connect to any available one. Then you can click on the blue arrow, which opens the connection info. Since you aren't connected yet, you need to click on the Settings button.

   

   If you want to know the MAC address of your wired connection, click on Wired in step 2.
