NAME

       Smokeping::probes::SSH - Secure Shell Probe for SmokePing

SYNOPSIS

	*** Probes ***

	+SSH

	binary = /usr/bin/ssh-keyscan # mandatory
	forks = 5
	offset = 50%
	step = 300
	timeout = 15

	# The following variables can be overridden in each target section
	keytype = dsa
	pings = 5
	port = 5000

	# [...]

	*** Targets ***

	probe = SSH # if this should be the default probe

	# [...]

	+ mytarget
	# probe = SSH # if the default probe is something else
	host = my.host
	keytype = dsa
	pings = 5
	port = 5000

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
