In order to find your MAC address on Linux, navigate to the "/sys/class/net" and identify the interface card you are interested in. Luckily for you, the MAC address can be accessed that way.
Find MAC Address by navigating the filesystemĪs you probably already know, on Linux, everything is a file.Īs a consequence, a lot of information is stored directly in plain files accessible by users on the filesystem. Using OUILookup, you are now able to search for your OUI vendor and have some more information about their location. Using this command, you will be listed with all the network interfaces available on your current server.Īs you can see, the result is pretty much the same than the one from the previous section (3a:2c:fb:46:63:be). In order to get your current MAC address, execute the “ip addr” command with the “show” option. In most cases, it is used in order to determine your current IP address, but it can also be used in order to get your MAC address. If you are a veteran system administrator, you are probably already very familiar with the “ip” command. However, using the “ifconfig” command is not the only way for you to get your MAC address. You successfully found your MAC address on Linux. Note : if you are dealing with a virtual machine, or if you are currently renting a VPS, you may be assigned a virtual MAC address that is not linked to a specific vendor.Īlso, if you have multiple network interfaces, they will all display their own individual addresses. The first three triplets are reserved for the OUI vendor (02:42:35 being the OUI vendor, and 54:98:2a the specific MAC address). In this case, you are interested in the layer 2 information, more precisely the ether MAC address.Īs you can see, when running the “ ifconfig” command, my current MAC address is 02:42:35:54:98:2a. RX and TX packets : linked to the actual cable used, RX and TX entries represent the packets you are able to receive versus the packets you are able to transmit.You are also given your default gateway IP address and netmask address. As a consequence, the layer 3 summarizes the information about your IP address (IPv4 and IPv6 addresses). Layer 3 information : most of the time, you will be dealing with TCP/IP networks.Layer 2 information : the information you are interested in : the MAC addresses as well as the layer 2 protocol used by the network card (in this case Ethernet).Network card general information : if the card is up or down, if it is running on unicast or multicast and its MTU.
For this network interface, you are presented with multiple different information :
