![]() ![]() Every PC’s network device should have a unique MAC address. MAC address is another critical parameter of a network device, including your PC’s hardware or a server. Typically, eth0 is for Ethernet connection, and wlp2s0 for Wireless connection.įor example, use eth0 : ip addr show eth0 Finding the MAC Address of the Linux System Inet6 1:2:00:33:333/64 scope global mngtmpaddr noprefixroute dynamic Valid_lft 548176sec preferred_lft 61403sec Inet6 AB:AD:AK:AI/64 scope global temporary dynamic Valid_lft 61791sec preferred_lft 61791sec Linux Host File: How to Edit and Use it?ġ: lo: mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000.In the output, you will receive the ARP reply from the destination system containing its MAC address. If your system has multiple NICs, you can specify from which interface a request should be sent using the -I flag (capital "i") followed by the interface name: sudo arping -c 1 -I interface_name įor instance, the following command will send one ARP request from its ens33 interface to the remote system's IP address 192.168.42.133. Once installed, find the MAC address of another system on a network by specifying its IP address as an argument using the following command: sudo arping -c 1 On RHEL-based distributions: sudo yum install arping ![]() On Debian-based distributions: sudo apt install arping You can install arping using the following commands: It is different from the ping utility which functions at the third layer. ![]() It functions at the second layer in the OSI model and sends the ARP request to the system to determine whether it is alive and responding. The arping utility helps you discover and probe local systems on a network. ![]()
