# condor\_power(1)

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

## NAME

condor\_power - HTCondor Manual

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

## SYNOPSIS

**condor\_power** \[**-h** \]

**condor\_power** \[**-d** \] \[**-i** \] \[**-m** *MACaddress*\] \[**-s** *subnet*\] \[*ClassAdFile* \]

## 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.

*condor\_power* relies 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.

## OPTIONS

- **-h**

  Print usage information and exit.

- **-d**

  Enable debugging messages.

- **-i**

  Read a ClassAd that is piped in through standard input.

- **-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 a mask for an IPv4 address. Without this option, a global broadcast will be sent.

## 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.
