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.
