I shouldn't be getting connection refused errors in the nagios interface, and cannot complete SSL errors in the windows server log, if check_nrpe - H host.com doesn't return an error? Shouldn't I be getting SSL errors, when I run check_nrpe against the host in question? To me this doesn't make sense, and I am at a loss as to the best place to look when attempting to fix this. Any suggestions and comments are appreciated. </blockquote> Are you sure you and Nagios are using the same check_nrpe? And are your commands that use it configured to use it the same way you're running it manually? I suspect not. Theoretically, yes... if you can run it at the command line successfully, Nagios should be able to run it successfully, too. That assumes, though, that you and Nagios are both running it the same way. If your check commands are configured in such a way that you're using different addresses for the -H parameter, there are permission problems with check_nrpe, you're passing different parameters to nsca, or any number of other possible differences, you may not get the same results in both cases. A little more detail on your specific problem, like how your checks are defined and the exact command line you're using to test, would make it a lot easier to give a more detailed answer. </body> </html>
