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.
