ETHER-WAKE(8)                                                    ETHER-WAKE(8)



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 for-
       mat,  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.

       -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 sta-
       tus  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.

AUTHOR
       The etherwake program was written by Donald Becker at Scyld Computing Corporation for  use  with  the  Scyld((TM))
       Beowulf System.
