Hello,

I would like to open a new ticket concerning problems I am having with Centreon NSClient on Windows Server 2016.

Old topic : 

 

I think that the resolution of the problem last time was a stroke of luck … Always the same mistake: “CHECK_NRPE STATE CRITICAL: Socket timeout after 10 seconds.”

Has anyone had this problem recently?

 

Here are the logs:

Can you share your nsclient.ini and the command line you’re executing?

Yes of course :

#   nscp settings --generate --add-defaults --load-all

#   nscp settings --activate-module <MODULE NAME> --add-defaults
# For details run: nscp settings --help

I use check_nrpe -H 127.0.0.1, locally on the machine, in the agent's directory.

I just tested on another server completely independent of my company's, and the result is the same. I still have an error.

Even disabling the windows firewall does not work.

I recompiled the installer with an old version of NSCP (0.5.2.35), I also have an error.

Hello
 

I invite you to test it from your poller.

But if you really want to test it from your Windows server, you can use this command:

check_nrpe.exe host=127.0.0.1 port=5666 payload-length=8192 insecure

It’s the same result :(

I had the same error message but the “insecure” option solved it:

Here it’s not the same message as previously.

What are the last entries in nsclient.log?

By adding ssl=0 in the command, I have a result. However, by adding "use ssl=false" in the nsclient.ini, it does not work. I added "ssl=0" in nsclient.ini, it doesn't work either.

HI, it appears that you need it on both ends:

  • ssl If this is true we will use SSL encryption on the transport. Notice this flag has to be the same on both ends or you will end up with strange errors. The flag is set on check_nrpe with the -n option (if you use -n no SSL will be used).

Great news ! 

 

I modified the nsclient.ini with insecure=false, and it’s work !

 

Thank you for your help!
