condor_power

send packet intended to wake a machine from a low power state

Synopsis

condor_power [-h]

condor_power [-d] [-m MACaddress] [-s subnet] [ClassAdFile]

Description

condor_power sends 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 ClassAdFile is given on the command line. With no command line arguments to specify the machine, and no file specified, condor_power quietly 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_power needs 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_power falls 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.

Options

-h

Print usage information and exit.

-d

Enable debugging messages.

-m MACaddress

Specify the MAC address in the standard format of six groups of two hexadecimal digits separated by colons.

-s subnet

Specify the subnet in the standard form of an IP address. Without this option, the default subnet used will be 255.255.255.255, causing a broadcast.

Exit Status

condor_power will exit with a status value of 0 (zero) upon success, and it will exit with the value 1 (one) upon failure.
