For example, here's how you can see if enp0s25 is up: $ cat /sys/class/net/enp0s25/operstate
You can check if an interface is up looking at operstate in the device directory. On a modern GNU/Linux system you can see the available network interfaces listing the content of /sys/class/net/, for example: $ ls /sys/class/net/ How do I find it ? Also it should work on all the Linux flavours. So in this case I want the HWaddr for eth1 and not eth0. NOTE : I have changed the values of the output. UP BROADCAST RUNNING MULTICAST MTU:123 Metric:123 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:123 it has an inet address, I even don't want one having inet6). So is there a way I could get the MAC address for the first available interface that is Active.(i.e. Also on OS X the interface names are different.Īlso the interface eth0 may be present but is unused.
TX packets:48515 errors:0 dropped:0 overruns:0 carrier:0 RX packets:54071 errors:1 dropped:0 overruns:0 frame:0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 In the output below, the MAC address is the hardware address (HWaddr), as highlighted below. After running "ifconfig" from the command line, you get output similar to the example below. If you are running Linux and Unix or a variant, you can determine the MAC address or hardware address using the ifconfig command.
