I have NSCP 0.5.2.39 (latest stable) version working with signed SSL certs (and even peer-cert verify mode), but it only works from the command “./nscp test”.
When I run it as a service, “check_nrpe” times out (as the NRPEServer of nscp.exe is not even listening on port 5666).
The nsclient.log reads:
error:B:\master\x64\dist\modules\NRPEServer\module.cpp:37: Exception in Failed to load NRPEServer: : Failed to open file: security/ca.pem
error:c:\source\master\service\plugin_manager.cpp:230: Plugin refused to load: NRPEServer
