etherwake - A tool to send a Wake-On-LAN "Magic Packet"
etherwake [options] Host-ID
DESCRIPTION
This manual page documents the usage of the ether-wake command.
etherwake 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
etherwake 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 the default "eth0".
-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.

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