condor_power send - packet intended to wake a machine from a low power state
condor_power[-d] [-i] [-m MACaddress] [-s subnet] [ClassAdFile]
condor_powersends one UDP Wake on LAN (WOL) packet to a machine specified either
by command line arguments or by the contents of a machine ClassAd. The machine
ClassAd may be in a file, where the file name specified by the optional
argument ClassAdFileis given on the command line. With no command line
arguments to specify the machine, and no file specified, condor_powerquietly
presumes that standard input is the file source which will specify the machine
ClassAd that includes the public IP address and subnet of the machine.
condor_powerneeds a complete specification of the machine to be successful. If a
MAC address is provided on the command line, but no subnet is given, then the
default value for the subnet is used. If a subnet is provided on the command
line, but no MAC address is given, then condor_powerfalls back to taking its
information in the form of the machine ClassAd as provided in a file or on
standard input. Note that this case implies that the command line
specification of the subnet is ignored.
condor_powerrelies on the router receiving the WOL packet to correctly broadcast
the request. Since routers are often configured to ignore requests to
broadcast messages on a different subnet than the sender, the send of a WOL
packet to a machine on a different subnet may fail.
- Print usage information and exit.
- Enable debugging messages.
- Read a ClassAd that is piped in through standard
- Specify the MAC address in the standard format of six
groups of two hexadecimal digits separated by colons.
- Specify the subnet in the standard form of a mask for an
IPv4 address. Without this option, a global broadcast will be sent.
condor_powerwill exit with a status value of 0 (zero) upon success, and it will
exit with the value 1 (one) upon failure.
