[ossec-list] ssh agentless monitoring (ssh_generic_diff)

[Matt]

Hello All,

I am starting to work with the agentless monitoring, and the first
host I'm working with is a non-Cisco switch.  I've modifed ossec.conf
like so:

    <agentless>
        <type>ssh_generic_diff</type>
        <frequency>120</frequency>  <!-- set to 120, just for testing
-->
        <host>sshu...@myhost.company.com</host>
        <state>periodic_diff</state>
        <arguments>show config</arguments>
    </agentless>

Restarting ossec, and the following relevant log entries appear:

2009/03/04 08:29:27 ossec-agentlessd: INFO: Started (pid: 7151).
... snip ...
2009/03/04 08:29:29 ossec-agentlessd: ERROR: Test failed for
'ssh_generic_diff' (126). Ignoring.

Any way to debug this further, or make the logging more verbose?  TIA
