I was unable to locate anything strange when I did a tail -f /var/log/messages on either machine. Thanks for the heads up on the command_check_interval setting. That was there for testing and I forgot to change it back. I'm not sure why the oscp_command is not executing on the distributed server when the configuration tells it to execute?? One strange thing to note though... If I run the script manually from the distributed server it connects for 10secs and then times out. This is the output of /var/log/messages on the central server... Dec 17 13:20:44 nsca[6650]: Handling the connection... Dec 17 13:20:54 nsca[6650]: End of connection... Thanks again!

I was hoping that someone might be able to help? Here is the configuration (sorry about the length)... <MARC> - Is there any error message in /var/log/messages on either machine? You might try enabling the debug option in nsca.cfg to get more detailed information. You should also try submitting a check result by calling send_nsca manually. That might spit out some errors. I'd also verify that nsca is listening on the IP/Port you expect it to be via netstat -aelp. Central Server (10.1.1.4) NSCA running in daemon mode with the following config... server_port=5667 [snip] <MARC> NSCA config looks fine at first glance. nagios.cfg has the following.. [snip] command_check_interval=30s <MARC> - This isn't valid for a 1.1 or below config AFAIK (it may be for a 2.0 config though). This should be an integer value specifying a multiple of the interval_length. For example, if you have your interval length set at 60 (seconds), then a 1 here would cause nagios to check for external commands every 60 seconds. 2 would mean every 120 seconds. The only odd value you could have here would be -1 which would cause nagios to check for external commands as often as possible. This could very well be your problem. A simple test would be to do an ls -l on rw/nagios.cmd and see if it's anything other than 0 length. If it's not then NSCA is successfully appending new results to the file but nagios may not be reading them. Distributed Server (10.1.1.3) [snip] <MARC> Distributed server information looked fine. It is interesting to note that your had the command_check_interval set to -1 here where I would expect the least number of external commands (if any) to be received. That's more of a work-flow thing anyway I would suspect. -- Marc </BODY> </HTML>
