.SH NAME

etherwake \- A tool to send a Wake-On-LAN "Magic Packet"
|
||
.SH SYNOPSIS
|
||
.B etherwake
|
||
.RI [ options ] " Host-ID"
|
||
.SH DESCRIPTION
|
||
This manual page documents the usage of the
|
||
.B ether-wake
|
||
command.
|
||
.PP
|
||
.\" TeX users may be more comfortable with the \fB<whatever>\fP and
|
||
.\" \fI<whatever>\fP escape sequences to invode bold face and italics,
|
||
.\" respectively.
|
||
\fBetherwake\fP 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
|
||
.BR ethers (5)
|
||
database specified in
|
||
.BR nsswitch.conf (5)
|
||
.
|
||
.SH OPTIONS
|
||
\fBetherwake\fP needs a single dash (´-´) in front of options.
|
||
A summary of options is included below.
|
||

|
||
.B \-b

.TP
|
||
.B \-i ifname
|
||
Use interface ifname instead of the default "eth0".
|
||
.TP
|
||
.B \-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.
|
||
|
||
.TP
|
||
.B \-V
|
||
Show the program version information.
|
||
|
||
.SH 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.
|
||
|
||
.SH SEE ALSO
|
||
.BR arp (8).
|
||
.br
|
||
.SH 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.
