Normally plugins are coded as if they are going to be used as active 

For a passive plugin, you need at least 3 arguments in addition to those 
required for the plugin to work:
1. hostname (as in Nagios config)
2. servicename (as in Nagios config)
3. /path/filename of the command file (usually /usr/local/nagios/var/rw/command)

The plugin must also output the return code on the status line.

Also the plugin must be running on the same system as Nagios and as a user 
who has permission to write to the Nagios command file.

It may just be easier to write a standard plugin and use nsca to send a 
passive response...
