SYNOPSIS

12       condor_power [-h ]
13
14       condor_power [-d ] [-i ] [-m MACaddress] [-s subnet] [ClassAdFile ]

DESCRIPTION

17       condor_power sends one UDP Wake on LAN (WOL) packet to a machine speci‐
18       fied either by command line arguments or by the contents of  a  machine
19       ClassAd.  The  machine  ClassAd  may  be in a file, where the file name
20       specified by the optional argument ClassAdFile is given on the  command
21       line.  With  no  command  line arguments to specify the machine, and no
22       file specified, condor_power quietly presumes that  standard  input  is
23       the  file  source  which will specify the machine ClassAd that includes
24       the public IP address and subnet of the machine.
25
26       condor_power needs a complete specification of the machine to  be  suc‐
27       cessful.  If a MAC address is provided on the command line, but no sub‐
28       net is given, then the default value for the subnet is used. If a  sub‐
29       net  is provided on the command line, but no MAC address is given, then
30       condor_power falls back to taking its information in the  form  of  the
31       machine  ClassAd  as provided in a file or on standard input. Note that
32       this case implies that the command line specification of the subnet  is
33       ignored.
34
35       condor_power relies on the router receiving the WOL packet to correctly
36       broadcast the request. Since routers are often configured to ignore re‐
37       quests to broadcast messages on a different subnet than the sender, the
38       send of a WOL packet to a machine on a different subnet may fail.

OPTIONS

41          -h     Print usage information and exit.
42
43          -d     Enable debugging messages.
44
45          -i     Read a ClassAd that is piped in through standard input.
46
47          -m MACaddress
48                 Specify the MAC address in the standard format of six  groups
49                 of two hexadecimal digits separated by colons.
50
51          -s subnet
52                 Specify the subnet in the standard form of a mask for an IPv4
53                 address. Without this option,  a  global  broadcast  will  be
54                 sent.
55

EXIT STATUS

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