Name

       condor_power 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_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.

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