Here is what I have done so far: On client: I’ve downloaded the nsca add-on and try to run the following command: send_nsca –H 10.0.10.124 –c send_nsca.cfg, but I get the error: Error: Server closed connection before init packet was received Error: Could not read init packet from server On server: I downloaded the nsca daemon and ran ./nsca –c nsca.cfg. I changed the nsca.cfg file’s allowed hosts to the host’s ip address. I also created a service to listen for passive checks and with no check command. How can I get the client to send the passive checks to the daemon running on the server? Thanks for any help. David </div> </body> </html>
