If you want to check the MAC address of all the network interfaces then you need to simply use ip addr sh command and check the MAC address from ether field as shown below.
LINUX FIND MAC ADDRESS OF ETH0 HOW TO
Method 3: How to find MAC Address in Linux Using ip addr sh command Hence Please use the network interface name with all the mentioned commands as per your system interface name or else none of the command will work. Please note that you might find eth0 network interface in your system instead of enp0s3. TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 If you want to check MAC Address of all the network interfaces in Linux using our traditional ifconfig command then you need to use ifconfig -a command as shown below. It will always show in this form 00:07:Y7:1C:6L:03.Īlso Read: 25 Useful Linux SS Command Examples to Monitor Network Connections Method 1: How to find MAC Address in Linux Using ifconfig command It is almost used in all the Network Devices which has network controller in it. It is a unique 48 bit(6-byte) address assigned to a Network Interface. MAC is abbreviated as Media Access Control. This is typically in-line with IEEE 802 Network technologies. You can find the usage of MAC address in wide range of Network Devices currently in use. You might be aware of Ethernet Card/Network Card/NIC Controller which works at Network level and is responsible for communicating with other network devices in a Network Topology. Mode:Managed Frequency:2.In this article, I will take you through different ways to List/Get/Display/Find MAC Address in Linux. To pick out your wireless MAC address type: iwconfig Make sure you register the right MAC address for the type of network connection wherever it is you’re going.
If you have a wireless card you will see more than one MAC Address, beginning wlan0 for the first card. The loopback adapter, lo, can be ignored because it is not a physical network device. You will find the hardware address listed after HWaddr. Most Linux distributions call the first Ethernet network adapter eth0, and subsequent adapters eth1, eth2, etc. TX packets:1364 errors:0 dropped:0 overruns:0 carrier:0 RX packets:1765 errors:0 dropped:0 overruns:0 frame:0 TX packets:1040 errors:0 dropped:0 overruns:0 carrier:0 RX packets:1040 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 The MAC address is referred to here as the HWaddr eth0 Link encap:Ethernet HWaddr 00:19:b9:5f:01:36 This will show you a list of the network adapters installed. To get the MAC address across all your network cards, the better solution is a terminal command: ifconfig You MAC Address is the hardware address at the top – but only for the active connection, be it wired or wireless. From the menu, select connection information to open the information pane, similar to that shown. If you have an active connection, you can click on the Network Manager icon in the notifications (panel) area of your desktop – see image top right, click to enlarge. It’s a base-16 value (hence called hexadecimal), so the letters A through F are treated as numeric values. The MAC Address is 12 digits long, broken up into pairs: 12:34:56:78:9A:BC. MAC Address numbers should be unique thanks to it’s length in hexadecimal notation and the MAC Address is difficult to fake. You’ll need to give your MAC Address to the network manager to add your device to the list of registered devices so that you can use the network. The MAC address is one way for wireless networks to restrict access to only those devices they can identify. If you travel around a lot, as I do, then you’ll often find the more secure locations with computer networks want to know the MAC address of any mobile devices you want to attach to their networks.
