Hi @BrunoLosse1,

We reviewed your files, and I have a few suggestions along a few questions.

1. Looks like your getting connection attempts from 10.63.24.130. What's running at this address?

2. You've got schedule jobs enabled. Is this intended? You can set Scheduler = 0 or I have attached another nsclient.ini file with the minimal settings that you can use.

3. Your file age checks such as ( check_nt! FILEAGE -l "d:\\Interfaces\SANTANDER\OUTBOX\GE200492\*.rem"! -w 600 -c 1800) are not working correctly. We tested the command here and it does work, so check your file path or permissions settings on the Window hosts. Also, this command does not support * in the file paths.

Let me know if you get it resolved.

Where did you get that? There's nothing with this IP.

I'm not sure I know what that means.

The path is correct, but there are no files there. Maybe that's the problem.
Is there a way to specify that I need any file with .rem extension? Can I do it using NRPE?

I've created a .txt file to test the command and it works fine with *
I still have two problems, the one I posted here https://support.nagios.com/forum/viewto ... =7&t=50931 and the fact that the command returns error if the folder is empty.

Hello,

As far the IP address, my apologies, as I entered the wrong address. I was looking at your log file and noticed this entry?: Rejected connection from: 10.63.225.130.

Another option is to use check_nrpe which will support more options. Please refer to the "NSClient++ via check_nrpe" section of the following document for example checks:

This is The IP of the old Nagios Server I was testing.

As far as the Nrpe, I can't get it to work for some reason...

Ok. That make sense.

When you run check_nrpe, what kind of error are you getting?

Code: Select all

cd /usr/local/nagios/libexec
./check_nrpe -H <host ip adddress>

I get the following error: CHECK_NRPE: (ssl_err != 5) Error - Could not complete SSL handshake with

@BrunoLosse1, Please replace your nsclient.ini file with the one I attached to this post. Then restart the nsclient service on your windows server. And execute this command from the nagios server:

cd /usr/local/nagios/libexec
./check_nrpe -H <host ip adddress>

Where <host ip adddress> is the windows server IP address.

Same error.
This is what I could see at the log that may help:
