check_rpc returns Unknown "Program -H is notdefined"

[John Daily]

If you look at the Perl code (at least for the latest version of the plugin), that error message can only result when the code thinks that -H is being passed as an argument (not a switch), or as the argument to -C.

I tried various broken invocations to reproduce your problem, but I couldn't.  Are you using the latest version of the plugin?

My version:   check_rpc (nagios-plugins 1.4.2) 1.8

It's extremely frustrating that there's no simple way to view the exact command being invoked by nagios.  It would seem likely that there's a spurious character or something else weird about the way it's being invoked.

I am running the command line test as the user nagios just like all of 
the other check command tests.

The working directory for "check_rpc" is the same as all of the other 
check commands. The error would indicate that the command is actually 
executing, yet it somehow does not know what to do with the -H switch 
when run by nagios per the services.cfg configuration.

Thanks,

Scott.
