![]() ![]() ifconfig -a | grep -ioE '(.)/ & print $1'Ĭoreutils. ![]() The same regex also works with PCREs ( -P). The -i makes the match case insensitive and the -o makes grep print only the matched portion. Hi, If you have root privileges, you can use ifconfig -a, which will display the MAC address along with the IPs. Here, I am looking for 5 repetitions of 2 letters or numbers followed by a colon, then any two characters. There are various regular expressions that will pick these up. Which is the most complete coverage I could find.Grep. (x86), IDE/ATA/ATAPI, PCMCIA (only tested on x86), SCSI and USB. currently supports DMI (x86 and IA-64 only), OpenFirmware device tree (PowerPC only), PCI/AGP, CPUID You can assign an IP address to the MAC and then access the IP that way: Microsoft Windows Windows systems require the dash '-' character between each digit of the MAC Address (Ethernet Address). Also, there is no mention of interfaces built on this piece of hardware. IF you can connect to the device you know the MAC of on the same network (ideally a cross-over cable). Notice that, even if you change the apparent MC address of the wifi card with macchanger, lshw will still display the true MAC address, contrary to ifconfig, which displays the changed one. Find Linux System Mac Address Using IP Command The ip command is part of the iproute2 package and can be used to. Then get the data from socket and using sprintf save mac address into buffer. Approaches to Finding MAC Address in Linux 1. First we open file descriptor and select network family ( AFNET) in case of IPv6 we use AFNET6. ![]() The MAC address is, of course, the serial number. To get MAC address we need to use some socket related stuffs, also need to use ioctl commands. Thanks Dwight You mentioned ifcfg-eth0 value being incorrect-I also had that problem because I replaced the motherboard. iproute2 First, you can check your current MAC address with the command: ip link show interface where interface is the name of your network interface. you swap the NIC-Dwight's answer is the key. Manually There are two methods for spoofing a MAC address: installing and configuring either iproute2 or macchanger. ![]() Lshw will do this for you: sudo lshw -C networkįor instance, my wifi card is displayed as follows: *-networkĬapabilities: pm msi pciexpress bus_master cap_list ethernet physical wirelessĬonfiguration: broadcast=yes driver=iwlwifi driverversion=3.11.0-15-generic firmware=18.168.6.1 latency=0 link=no multicast=yes wireless=IEEE 802.11abgn The other answers above are good for a working interface, but if you're trying to find the MAC to configure a new interface-e.g. ![]()
