Wake On Lan - Novell LINUX ENTERPRISE SERVER 10 - INSTALLATION AND ADMINISTRATION 04-08-2006 Installation Manual

4.3.6 Preparing the Target System for Wake
Wake on LAN (WOL) requires the appropriate BIOS option to be enabled prior to the
installation. Also, note down the MAC address of the target system. This data is needed
to initiate Wake on LAN.

4.3.7 Wake on LAN

Wake on LAN allows a machine to be turned on by a special network packet containing
the machine's MAC address. Because every machine in the world has a unique MAC
identifier, you do not need to worry about accidentally turning on the wrong machine.
IMPORTANT: Wake on LAN across Different Network Segments
If the controlling machine is not located in the same network segment as the
installation target that should be awakened, either configure the WOL requests
to be sent as multicasts or remotely control a machine on that network segment
to act as the sender of these requests.
Users of SUSE Linux Enterprise Server 9 and higher can use a YaST module called
WOL to easily configure Wake on LAN. Users of other versions of SUSE Linux-based
operating systems can use a command line tool.
