NAME
       ether-wake - A tool to send a Wake-On-LAN "Magic Packet"

SYNOPSIS
       ether-wake [options] Host-ID

DESCRIPTION
       This manual page documents the usage of the ether-wake command.

       ether-wake  is a program that generates and transmits a Wake-On-LAN (WOL) "Magic Packet", used for restarting machines that have been soft-
       powered-down (ACPI D3-warm state). It generates the standard AMD Magic Packet format, optionally with  a  password  included.   The  single
       required  parameter  is	a station (MAC) address or a host ID that can be translated to a MAC address by an ethers(5) database specified in
       nsswitch.conf(5)

OPTIONS
       ether-wake needs a single dash ('-') in front of options.  A summary of options is included below.

       -b     Send the wake-up packet to the broadcast address.

       -D     Increase the Debug Level.

       -i ifname
	      Use interface ifname instead of sending a wake packet to all interfaces.

       -p passwd
	      Append a four or six byte password to the packet. Only a few adapters need or support this. A six byte password may be specified	in
	      Ethernet	hex format (00:22:44:66:88:aa) or four byte dotted decimal (192.168.1.1) format.  A four byte password must use the dotted
	      decimal format.

       -V     Show the program version information.

EXIT STATUS
       This program returns 0 on success.  A permission failures (e.g. run as a non-root user) results in an exit status of  2.   Unrecognized	or
       invalid	parameters  result  in	an exit status of 3.  Failure to retrieve network interface information or send a packet will result in an
       exit status of 1.

SEE ALSO
       arp(8).

SECURITY
       On some non-Linux systems dropping root capability allows the process to be dumped, traced or debugged.	If someone  traces  this  program,
       they get control of a raw socket.  Linux handles this safely, but beware when porting this program.

       The ether-wake program was written by Donald Becker at Scyld Computing Corporation for use with the Scyld(tm) Beowulf System.
