Как узнать mac в линуксе

How can I see my mac address on Ubuntu?

As described in the newer answer below, the modern solution is to run:

The MAC address is shown in the link/ether field.

Original Answer

Open a terminal and run ifconfig:

This answer needs to be deprecated given that the system doesn’t even come with ifconfig anymore. Someone like me looking for how to find the ip address without internet working can’t just intstall the obsolete utllity.

Use ip command instead of the outdated ifconfig

link/ether field of the output is the MAC address (Both for Wi-fi and ethernet connections, MAC address is represented by link/ether ). Mostly this will be present in the second line.

$ ip addr show 1: enp2s0: mtu 1500 qdisc mq state UP group default qlen 1000 link/ether a0:54:9f:53:b2:6e brd ff:ff:ff:ff:ff:ff 

In my case a0:54:9f:53:b2:6e is the MAC address.

On Ubuntu 20.04.02 LTS, there is no HWaddr in the output from ifconfig . Instead, look at ether :

Try ifconfig, and look at the «HWaddr».

okay, this is a very easy solution. 1/ Open a terminal 2/ ifconfig A list of network capable devices will be displayed. If you are using wireless, it usually is called wlan0, but can also be named pan0 wifi0 etc. A physical conection is most likely eth0. on the first line you will see your mac address. here is a sample of what you might see eth0 Link encap:Ethernet HWaddr 00:00:00:00:00:00

You can spoof your mac address too with macchanger (sudo aptitude install macchanger) just type man macchanger to learn more

You can also right-click on the GNOME Network Manager. There you choose connection information and the following window shows you the hardware address. See also NetworkManager at Ubuntus Wiki.

Как узнать mac адрес компьютера в Linux

Для каждой сетевой карты дистрибутива Linux существует свой аппаратный адрес. Однако мало кто из новичков знает, где добыть эту информацию на своём ПК. Труднее всего это дается пользователям, которые привыкли работать с Windows. Но трудности в этом вопросе не так велики, как кажутся на первый взгляд. Чтобы узнать Mac-адрес, можно воспользоваться специальными утилитами, о которых вы узнаете прямо сейчас.

Утилита IP

IP не нужно устанавливать вручную – она наличествует в Линукс по умолчанию. Пользователю лишь остается её вызвать: $ ip a В открывшемся окне указаны те же самые интерфейсы, только в иной поочередности. Далее нужно повторить конструкцию предыдущей команды с небольшими коррективами: $ ip a | grep ether | gawk ‘’ Более подробно о команде IP написано в другой статье как пользоваться ip в линукс

Сетевая программа ifconfig

Консольная утилита ifconfig считается слегка устарелой на сегодняшний день. Ей можно подобрать замену в виде утилиты ip. Примечательно, что она функционирует примерно так же, как и её предшественница. ifconfig позволяет быстро получить нужную информацию, как только пользователь установит её на свой ПК. Чтобы становить нужный пакет с программами, необходимо ввести в окне терминала специальную команду: $ sudo pacman -S net-tools Если есть необходимость установить утилиту в Debian или Ubuntu, попробуйте следующий способ: $ sudo apt install net-tools Теперь попробуйте найти Mac-адрес Linux в перечне интерфейсов. Введите в терминале: $ ifconfig -a В открывшемся окне вы увидите 2 различных интерфейса. Они подписаны следующим образом: «enp0s7» и «lo». Вам потребуется первый блок с данными. Mac-адрес карты будет прописан напротив слова «ether». Для полного отображения адреса задайте следующее: $ ifconfig -a | grep ether | gawk ’’ Более подробно о команде ifconfig написано в другой статье: www.vseprolinux.ru/ifconfig

Заключение

Поиск информации относительно Mac-адреса в операционной системе Линукс осуществляется посредством двух альтернативных и очень похожих между собой программ. Их отличия между собой действительно незначительны. Тем не менее, владельцы дистрибутива Linux получили от разработчиков выбор. Новые версии системы по умолчанию оснащены утилитой ip. Старые версии имеют в своем арсенале утилиту ifconfig, отошедшую на второй план в обновленных версиях операционной системы. Если таковой не имеется изначально, но очень хочется заполучить её для нового компьютера, пользователь должен установить данную утилиту самостоятельно. О том, как инсталлировать программу, говорилось выше.

How to Find Network MAC Address in Linux System

The term MAC Address is a derived abbreviation for Media Access Control Address. The network interface controller (NIC) uses the MAC address as its assigned unique identifier within an existing network segment.

To practically relate to or understand what a MAC address is, think of it as the postal or physical address to a house. The house in this case is the network interface controller (NIC).

There is a key difference between MAC address and IP address and therefore we should not confuse the two. MAC address identifies the device you are using since it is imprinted on the device hardware whereas IP address identifies the connection status among devices seeking to communicate on an existing/configured network.

The MAC address of any device is represented by a 12-digit hexadecimal number. Its display includes a colon or hyphen after every two MAC address digits for easy readability.

For instance, a MAC address can be represented in the following manner.

aa:bb:cc:dd:ee:ff or gg-hh-ii-jj-kk-ll

Approaches to Finding MAC Address in Linux

Depending on the number of network interfaces on your Linux machine like Wi-Fi built-in and Ethernet port, your computer can be associated with more than one MAC Address.

1. Find Linux System Mac Address Using IP Command

The ip command is part of the iproute2 package and can be used to display both the MAC address and IP address of your Linux-powered machine using either of the following commands.

$ ip addr or $ ip address or $ ip address show

Depending on the network adapter or interface present, we can see the availed MAC addresses. In the above screen capture, three distinct MAC addresses can be identified from the ip address command.

Another useful command is the ip link which only focuses on the MAC address and does not display the IP addresses.

2. Find Linux System Mac Address Using Ifconfig Command

The ifconfig command is another effective approach to identifying the MAC address of your Linux machine. We however need to install it first since it is a member of the net-tools package and not installed on Linux by default.

$ sudo apt install net-tools [On Debian, Ubuntu and Mint] $ sudo yum install net-tools [On RHEL/CentOS/Fedora and Rocky Linux/AlmaLinux] $ sudo emerge -a sys-apps/net-tools [On Gentoo Linux] $ sudo pacman -S net-tools [On Arch Linux] $ sudo zypper install net-tools [On OpenSUSE]

Once installed, run the ifconfig command to find the IP address and MAC address of your Linux system.

Different network interfaces or adapters showcase different MAC addresses as highlighted in the above screen capture.

We have successfully defined and understood how to get the MAC address(es) on our Linux machines.

How to Find Your MAC address in Ubuntu and Other Linux Distros

When you are learning networking or troubleshooting it, you would need to know the MAC address.

A computer can have more than one MAC address. It is because the MAC address is a core part of networking, and each networking peripheral device has its own MAC address.

So, your WiFi card has a MAC address, and so does the Ethernet (LAN) port. Even the Bluetooth has one.

The MAC address, also known as the physical address, is a 12-digit hexadecimal code (48-bits) and is represented as MM:MM:MM:SS:SS:SS

In this tutorial, I’ll share the steps for finding the MAC address of your desired networking interface in Linux. I’ll show both command line and GUI methods.

Method 1: Find MAC address using command line

There are serveral Linux networking commands that can be used to get the MAC address of the WiFi or LAN cards.

Open up your terminal and use the following command, and it will bring the address of the present network cards in your system:

And you’ll be met with the following output:

Generally, the wireless device names will be wlan0, wlan1, wlan2, wlo0, wlo1, and wlo2, whereas the Ethernet (wired device) will probably have eth0, eth1, eno0, eno1,enpls0, or enpls1.

You can find the MAC address of each device at the last line of the device description, followed by link/ether and it’s 52:54:00:5c:92:bf in my case.

Get the MAC address of Bluetooth

As I mentioned earlier, all networking devices have a physical address. If you want to see the MAC address of your Bluetooth adapter, you can use this command:

You can see it beside the BD Address field.

[email protected]:~$ hciconfig hci0: Type: Primary Bus: USB BD Address: DC:41:A9:FB:7A:C4 ACL MTU: 1021:4 SCO MTU: 96:6 UP RUNNING RX bytes:17895787 acl:275 sco:250783 events:298882 errors:0 TX bytes:303664302 acl:295384 sco:249895 commands:3380 errors:0

You can also use the bluetoothctl command here.

Method 2: Get MAC address using GUI

If you’re afraid of using the terminal you can use the network settings to get the MAC address details.

I am using Ubuntu with the GNOME desktop environment. If you use some other desktop environments, the screenshots may not look the same.

First, search for settings in the system menu and open the first result.

Now, for the left menu bar, select Network and click on the little gear icon located near to wired network toggle. Even if you’re not connected to a wired network, you can still follow the same approach.

If you’re on Wi-Fi, there will be an option for Wi-Fi in the left menu bar. From there, you have to follow the same approach (clicking on the gear icon) to get your MAC address.

Once you click on the gear icon, you’ll be met with details of the selected network interface. Here, the MAC address is given as the Hardware address.

Here you have it in the easiest way possible!

Final Words

Did you know that the first half of hexadecimal code (24 bits) is used to represent the manufacturer of your network adapter?

Finding a MAC address in Linux is quite easy as you have seen it here. On the same note, you may like to learn about changing the MAC address in Linux.

Let me know if you have any questions or suggestions.
