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

VVAARRIIAABBLLEESS
       Supported probe-specific variables:

       binary
           This variable specifies the path of the remote shell program (usu-
           ally 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.

       hostinterval
           The fping "-p" parameter, but in (possibly fractional) seconds
           rather than milliseconds, for consistency with other Smokeping
           probes. From _f_p_i_n_g(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 _f_p_i_n_g(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 num-
           ber 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 rrhhoosstt option specifies the remote device from where fping will
           be launched.

           Example value: my.pinger.host

           This setting is mandatory.

       ruser
           The (optional) rruusseerr 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 _f_p_i_n_g(1):

           Set source address.

           Example value: 192.168.0.1

       step
           Duration of the base interval that this probe should use, if dif-
           ferent from the one specified in the 'Database' section. Note that
           the step in the RRD files is fixed when they are originally gener-
           ated, 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

NNOOTTEESS
       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 rrhhoosstt, rruusseerr and rrbbiinnaarryy 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.

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