DESCRIPTION

       Integrates the remote execution of FPing via ssh/rsh into smokeping.  The variable binary
       must point to your copy of the ssh/rsh program.  The variable rbinary must point to your
       copy of the fping program at the remote end.

VARIABLES

       Supported probe-specific variables:

       binary
           This variable specifies the path of the remote shell program (usually ssh, rsh or
           remsh). Any other script or binary that can be called as

           binary [ -l ruser ] rhost rbinary

           may be used.

           Example value: /usr/bin/ssh

           This setting is mandatory.

       blazemode
           Send an extra ping and then discarge the first answer since the first is bound to be
           an outliner.

           Example value: true

       hostinterval
           The fping "-p" parameter, but in (possibly fractional) seconds rather than
           milliseconds, for consistency with other Smokeping probes. From fping(1):

           This parameter sets the time that fping  waits between successive packets to an
           individual target.

           Example value: 1.5

       mininterval
           The fping "-i" parameter, but in (probably fractional) seconds rather than
           milliseconds, for consistency with other Smokeping probes. From fping(1):

           The minimum amount of time between sending a ping packet to any target.

           Example value: 0.001

           Default value: 0.01

       offset
           If you run many probes concurrently you may want to prevent them from hitting your
           network all at the same time. Using the probe-specific offset parameter you can change
           the point in time when each probe will be run. Offset is specified in % of total
           interval, or alternatively as 'random', and the offset from the 'General' section is
           used if nothing is specified here. Note that this does NOT influence the rrds itself,
           it is just a matter of when data acqusition is initiated.  (This variable is only
           applicable if the variable 'concurrentprobes' is set in the 'General' section.)

           Example value: 50%

       packetsize
           The ping packet size (in the range of 12-64000 bytes).

           Example value: 5000

       pings
           How many pings should be sent to each target, if different from the global value
           specified in the Database section. Note that the number of pings in the RRD files is
           fixed when they are originally generated, and if you change this parameter afterwards,
           you'll have to delete the old RRD files or somehow convert them.

           Example value: 20

       rbinary
           The location of your fping binary.

           Example value: /usr/bin/fping

           This setting is mandatory.

       rhost
           The rhost option specifies the remote device from where fping will be launched.

           Example value: my.pinger.host

           This setting is mandatory.

       ruser
           The (optional) ruser option allows you to specify the remote user, if different from
           the one running the smokeping daemon.

           Example value: foo

       sourceaddress
           The fping "-S" parameter . From fping(1):

           Set source address.

           Example value: 192.168.0.1

       step
           Duration of the base interval that this probe should use, if different from the one
           specified in the 'Database' section. Note that the step in the RRD files is fixed when
           they are originally generated, and if you change the step parameter afterwards, you'll
           have to delete the old RRD files or somehow convert them. (This variable is only
           applicable if the variable 'concurrentprobes' is set in the 'General' section.)

           Example value: 300

       timeout
           The fping "-t" parameter, but in (possibly fractional) seconds rather than
           milliseconds, for consistency with other Smokeping probes. Note that as Smokeping uses
           the fping 'counting' mode (-C), this apparently only affects the last ping.

           Example value: 1.5

       tos Set the type of service (TOS) of outgoing ICMP packets.  You need at laeast
           fping-2.4b2_to3-ipv6 for this to work. Find a copy on www.smokeping.org/pub.

           Example value: 0x20

NOTES

       It is important to make sure that you can access the remote machine without a password
       prompt, otherwise this probe will not work properly.  To test just try something like
       this:

           $ ssh foo@HostA.foobar.com fping HostB.barfoo.com

       The next thing you see must be fping's output.

       The rhost, ruser and rbinary variables used to be configured in the Targets section of the
       first target or its parents They were moved to the Probes section, because the variables
       aren't really target-specific (all the targets are measured with the same parameters). The
       Targets sections aren't recognized anymore.

BUGS

       This functionality should be in a generic 'remote execution' module so that it could be
       used for the other probes too.
