This is an old plugin for which I am looking for a replacement. Looks like it might have went away with netsaint. Following is the output from -h. Does anyone know if there is a newer version of this or if there is a replacement plugin? I couldn't find anything like it in the new nagios-plugins-1.4.3 distribution.
