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.
