If it is not applicable, like for the loopback interface, 00:00:00:00:00:00 is shown instead. is it the link/ether field under eth0 Yes, that is the MAC address. Strcpy(mac, ether_ntoa((ether_addr *) ifr.ifr_hwaddr. The command ip link shows the MAC address on all interfaces. Int fd = socket(PF_INET, SOCK_DGRAM, IPPROTO_IP) Finally, we print MAC address to the console.
Note that we create a character array with a size of 18 (17 characters for the MAC address string, plus a null terminator). Using the ether_ntoa function, we convert the binary MAC address to a human-readable string. The MAC address is returned to the ifr_hwaddr member of the ifreq structure. In the following code, we create a socket, initialize an ifreq structure with the name of the interface ( wlo1 in this case), and call the ioctl function. We can use the ioctl function with the SIOCGIFHWADDR request to retrieve the MAC address for a specified network interface on Linux. This tutorial explains how to get the MAC address on Linux using C++. Getting the MAC address of a network interface is useful in many situations, especially in network administration, security, diagnostics and device identification. The getmac (short for get MAC address) is a simple Windows network command-line utility used to find the physical address of the network adapters (NIC) in a. A MAC (Media Access Control) address is a unique value assigned to a network interface card (NIC, also called network adapter) by the manufacturer to uniquely identify it.
