Nagios Support Forum

HI Everyone,

I'm currently setting up services on our servers, so far I've installed NSCP++ on two of our production servers, TS1 and TS2. I have TS1/2 setup the same way the nsclient.ini states;

[/settings/default]
allowed hosts = 192.168.1.11
password = N0rth3dgE

[/modules]
NSClientServer = 1
CheckSystem = 1
CheckDisk = 1
NRPEServer = 1

[/settings/NRPE/server]
use ssl = 1
payload length = 1024
allow nasty characters = false
allowed ciphers = ADH
ssl = 1
allow arguments = 1
insecure = 1

However on TS1 its showing as Connection Refused, but TS2 it works. I have nmap -p 12489 192.168.87.41

Starting Nmap 6.00 ( http://nmap.org ) at 2015-06-03 13:12 BST
Nmap scan report for 192.168.87.41
Host is up (0.028s latency).
PORT STATE SERVICE
12489/tcp open unknown

Any ideas on how I can resolve this?

Did you restart your service after you wrote out/updated your nsclient.ini?

I did, there's no firewall on this server and nmap can see it. Is there a log anywhere I can look for?

Its' also happening on one of the other servers, basically I added in 10 servers and 2 of them show refused connection but I can see them in Hosts and ping fine and nmap is showing its open.

If it's actually getting ahold of the nscp daemon there should be some log information at

The 1.11 is the nagios server but not sure what the .12 is, however its being blocked.

Something is haywire with the config I'd say - I'm fairly certain that's the line you'd get if allowed_hosts isn't proper.


Maybe some funky newline character or weird spaces or quoting making the allowed_hosts unreadable? Maybe just a fat-finger somewhere? Maybe net stop nscp, net start nscp isn't working properly?

I've had a look at the command, i've added into it -s THEPASSWORD and -p but this still doesn't seemed have worked.
#CPU Load over 10 Min, 60 Min, 24 hrs

define command{
command_name check_nt_cpu_avg
command_line $USER1$/check_nt -H $HOSTADDRESS$ -s THEPASSWORD -p 12489 -v CPULOAD -l 10,60,95,60,60,95,1440,60,95
}

Did i miss something on the command?

Actually by adding the -p part it has worked. So thanks for listening.

Actually before closing this, one of the servers is getting this;
