Configuration Help

[Jason126]

Currently I am having problems with nagios gaining access to be able to retrieve service updates from workstations. Currently I have a workstation setup so that it will send CPU Usage, Disk Usage, Memory Usage, ect. The problem is is that nagios says "Connection Refused", When I attempt to reconfigure a particular workstation I receive the message "Configuration Verification failed". For some reason nagios cannot connect to any workstations. This is all in an internal network so no ports needs to be opened, NSClient++ is installed and windows firewall is turned off. I'm not sure what I might be missing.

Any help would be appreciated.

Thanks!

Lets start by checking the ports from the XI server. On the XI server:

Code: Select all

nmap <ip of remote windows host> -p 12489

If it is closed, check to make sure that the service is running on the windows box.
If it is filtered, a network device is firewalling access to port 12489.
If it is open, move on to checking your password. On the XI server:

Code: Select all

/usr/local/nagios/libexec/check_nt -H <ip of windows server> -s "<password>" -p 12489 -v CLIENTVERSION

If you get the version back, then everything is working and the problem lies in your NSClient configuration file or the check configuration on the XI server.

I've attempted opening ports on both the windows machine and the nagios server, but It keeps saying that port 12489 is closed, I also did it on my sonicwall/firewall just incase and no go.

/usr/local/nagios/libexec/check_nt -H <ip of windows server> -s "<password>" -p 12489 -v CLIENTVERSION #This command returns back "Could not fetch information from server"

Is there something else I should be doing? NSClient++ is a running service.

Make sure that the NSClient++ service is running first. Next, run the following command on your nagios server and show the output (hide sensitive info):

Code: Select all

nmap <ip of remote windows host> -p 12489
