DESCRIPTION

       Integrates ssh-keyscan as a probe into smokeping. The variable binary must point to your
       copy of the ssh-keyscan program. If it is not installed on your system yet, you should
       install openssh >= 3.8p1

       The Probe asks the given host n-times for it's public key, where n is the amount specified
       in the config File.

       As part of the initialization, the probe asks 127.0.0.1 for it's public key and tries to
       parse the output. Make sure you have SSH running on the localhost as well.

VARIABLES

       Supported probe-specific variables:

       binary
           The location of your ssh-keyscan binary.

           Example value: /usr/bin/ssh-keyscan

           This setting is mandatory.

       forks
           Run this many concurrent processes at maximum

           Example value: 5

           Default value: 5

       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%

       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
           How long a single 'ping' takes at maximum

           Example value: 15

           Default value: 5

       Supported target-specific variables:

       keytype
           Type of key, used in ssh-keyscan -t keytype

           Example value: dsa

           Default value: rsa

       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: 5

       port
           Port to use when testing the ssh connection -p port

           Example value: 5000

           Default value: 22
