NAME
powerwake - smart utilty for remotely waking sleeping systems
SYNOPSIS
powerwake [-b|--broadcast BROADCAST_IP] [-m|--method METHOD]
TARGET_MAC|TARGET_IP|TARGET_HOST
OPTIONS
-b|--broadcast BROADCAST_IP
Optional parameter specifying the broadcast ip. If unspecified,
the default is 255.255.255.255.
-m|--method METHOD
Currently, ’wol’ is the only supported method.
TARGET_MAC|TARGET_IP|TARGET_HOST
The target system to powerwake may be identified by MAC address,
or by an IP/hostname cached in (the current arp(8) table,
/etc/ethers, /var/cache/powerwake/ethers).
DESCRIPTION
The powerwake utility compliments the powernap(8) daemon.
Administrators can run the powernap utility on remote hosts, allowing
them to sleep when un-utilitized. To awake the remote system, use
powerwake.
Powerwake is designed to be "smart", and support multiple methods of
waking remote hosts, such as wakeonlan, ipmi, and others. Currently,
wakeonlan is the only implemented mechanism, though others are
intended.
Powerwake is also "smart" in that it can take MAC address, hostnames,
or ip addresses. In the case of a hostname or ip address, powerwake
will first load a dynamically maintained cache file
/var/cache/powerwake/ethers, then a statically administered
configuration file /etc/ethers, and finally use the arp table to
determine the target MAC address. The cache will be updated
accordingly.
