If it's not working, then allow arguments = 1 is in the wrong place. The document outlines specifically where it needs to be under which pertains directly to NRPE.

I would make sure it's there, and then restart the NSClient++ service. After doing so, attempt to run the check, and if it fails again please post your nsclient configuration file.

hello, finally works, thank you very much
at the end the problem is what we were saying, the nsclient.ini file must be very well ordered

so it did not work

Code: Select all

[/ Settings / NRPE / server]
NRPEServer = 1
allow arguments = 1
nasty_meta allow chars = 1
use SSL = 1
and so all ok

Code: Select all

NRPEServer = 1
[/ Settings / NRPE / server]
allow arguments = 1
nasty_meta allow chars = 1
use SSL = 1
thank you very much for the help, you can close the thread

Fixed external plugin check_tcp

But now I work the basic plugins check_nt
I get the following error
nSorolla address and connect to port 12489: Connection refused


For example: Server Uptime

CRITICAL 09-30-2016 9:13:26 0d 0h 8m 43s 3/3 nSorolla address and connect to port 12489: Connection refused

This is my configuration file nsclient.ini

Code: Select all

# If you want to fill this file avalible With all options run the following command:
# Nscp settings --add-defaults --generate --load-all
# If you want to activate a module and bring all its options in use:
# Nscp settings --activate-module <module name> --add-defaults
# For details run: nscp settings --help

I would suggest including the following settings above your [settings / NRPE / server section]:

Code: Select all

; Section for NSClient (NSClientServer.dll) (check_nt) protocol options.
[/settings/NSClient/server]

; ENABLE SSL ENCRYPTION - This option controls if SSL should be enabled.
use ssl = 0

; PERFORMANCE DATA - Send performance data back to Nagios (set this to 0 to remove all performance data).
performance data = 1

; PORT NUMBER - Port to use for check_nt.
port = 12489
I would also verify that Windows Firewall (or other firewalls) are not blocking traffic on port 12489

Hello
The port 12489 is open.
If I have this configuration, the standard plugins check_nt work and check_tcp external plugin does not work, it gives this error when I run

Code: Select all

check_tcp = scripts \ check_tcp.exe -H $ ARG1 $ -p $ ARG2 $ -w $ ARG3 $ -c $ ARG4 $
If I make changes in the nsclient tell me file, I check_tcp external plugin works but let me run the standard plugins check_nt

Run the external plugin

Code: Select all

 / Usr / local / nagios / libexec / H check_nrpe check_tcp -a-c server1 server1 80100200
TCP OK - 0.000 second response time on port 80 | 'time' = 0.00039s
but the basic plugins do not work

Code: Select all

check_test = check_test.ps1



[/ Settings / external scripts / scripts]

check_tcp = scripts \ check_tcp.exe -H $ ARG1 $ -p $ ARG2 $ -w $ ARG3 $ -c $ ARG4 $


I've added

; Section for NSClient (NSClientServer.dll) (check_nt) protocol options.
[/ Settings / NSClient / server]

; ENABLE SSL encryption - SSL This option controls if Should be enabled.
use ssl = 0

; PERFORMANCE DATA - Send performance data back to Nagios (set to 0 to remove esta all performance data).
performance data = 1

; PORT NUMBER - Port to use for check_nt.
port = 12489
But I still fail the standard plugins, external plug-in this case works for me.

Sorry for the inconvenience and thank you very much for the help, see if you can continue helping me thanks

In your second configuration file, move this part -

Code: Select all

; undocumented key
NSClientServer = 1
To be under this part -

Code: Select all

; undocumented section
[/ Modules]
NSClientServer = 1 is what controls if check_nt is on or not. Once you make this change, and restart the service, both check_nrpe with exernal arguments and check_nt should work. If not, please post your current configuration file once again.

Yes now
NSClient Server = 1

It works !!!
Thank you very much, and you can close the thread
