Strcpy(mac, ether_ntoa((ether_addr *) ifr.ifr_hwaddr. 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). This will show all the network interfaces and the corresponding MAC address for each one. (either due to missing driver support or bad/mis-identified hardware) check dmesg to confirm that 'eth0' is detected by the system at all. that means the device is not detected in the machine. Using the ether_ntoa function, we convert the binary MAC address to a human-readable string. The easiest way to find the MAC address on any Linux computer is to use the command ip link. 4 Answers Sorted by: 14 if there is no entry in ifconfig -a. 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. 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.
