Wake-on-LAN (WOL) is an Ethernet networking standard that allows a server to be turned on by a network message. You need to send ‘magic packets’ to wake-on-lan enabled ethernet adapters and motherboards, in order to switch on the called systems. Make sure you connect the NIC (eth0 or eth1) with the motherboard, and enable the WOL function in the BIOS. This is a quick guide to enable WOL under RHEL / Fedora / CentOS / Debian / Ubuntu Linux.
Media Access Control (MAC) address is a unique identifier attached to most networking devices (such as router, Ethernet cards, servers, nas devices, switches and so on).
This blog posts demonstrates how to get the Media Access Control (MAC) address for an ethernet adapter under Linux, Unix, Apple OS X, and *BSD operating systems using command line options.
