I'm interested in using the nsca addon - but only the daemon. I thought I could just open an tcp connection to the daemon and send my update manually: echo "3\t1\tmt-ubuntu\tSMTP Availability\tFAIL\n" | netcat nocnag02 5667 I set the value decryption_method=0 in the server config file (because I'm not doing any encryption on the client end). Is this possible? I looked through the source and tried to create the necessary string - but I'm thinking I'm missing something. Any ideas? Feel free to tell me I'm way off here. Matt
