Final answer:
To find the MAC address of a Linux-based machine, use the 'ifconfig' command or 'ip link' on newer systems in the terminal, which will display network configuration details including the MAC address.
Step-by-step explanation:
If you need to find out the MAC address of a Linux-based machine, you can use the command-line utility called ifconfig. After opening a terminal on the Linux machine, you can run the command 'ifconfig' or in newer systems, you might need to use 'ip link'. The ifconfig command or 'ip link' will display network configuration details including the MAC address. The MAC address is usually listed as HWaddr or ether for respective interfaces.The command-line utility that can be used to ascertain the MAC address of a Linux-based machine is the ifconfig command.
To use the ifconfig command, open the terminal and type ifconfig. This command will display the network interfaces and their respective MAC addressesFor example, the output might look like this:eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.1.10 netmask 255.255.255.0 broadcast 192.168.1.255 inet6 fe80::250:56ff:feab:cdef prefixlen 64 scopeid 0x20<link> ether 00:50:56:ab:cd:ef txqueuelen 1000 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
