NSClient++

[tgriep]

In one of your earlier posts, you said that you were getting the following error
NSClient - ERROR: Invalid password.
Where are you seeing that error and can you provide a screen capture of the error?

Have you created and service check commands on the Nagios server to check that windows host?
If so, you would edit those configs and change the password there.

Here is the output of /usr/local/nagios/etc/objects/windows.cfg

The windows.cfg file only has the host checks and not the service checks.
That is not the file you will have to edit, but it should be in the /usr/local/nagios/etc/objects/ folder.
One way to find the correct file is to grep for one of the service descriptions that are having the error. Use this example below.

Code: Select all

grep -R "CPU Load" /usr/local/nagios/etc/

The output of the grep should show you the file you will have update the NSClient password.

One thing you should do is keep track of the files you are editing so if you have to change something, you know what was done, and when it was done.

Open those files, find the password and change it to the same password that you set in the nsclient.ini file.

[donnyforbes]

I checked both of these files.
/usr/local/nagios/etc/objects/commands.cfg
/usr/local/nagios/etc/objects/windows.cfg

I don't see anywhere in these files for NSClient password. Am I missing something here?

[donnyforbes]

Do I need to add something to both those files? I checked both locations for those files and did not see anything to do with password in them.
This is really strange...

[tgriep]

Take a look at this link.
https://assets.nagios.com/downloads/nag ... ndows.html
Especially the section called "Password Protection". It explains where to put the password in the nagios config files that is used in the nsclient.ini file.

[dwhitfield]

You need to give us the full config. It looks like you are just giving us what is showing on the screen at a particular time.

The following should aid you in your search:

Code: Select all

grep -n check_nt /usr/local/nagios/etc/objects/commands.cfg
grep -n check_nt /usr/local/nagios/etc/objects/windows.cfg

[donnyforbes]

found it. See below.

# 'check_nt' command definition
define command{
command_name check_nt
command_line $USER1$/check_nt -H $HOSTADDRESS$ -p 12489 -s AtL@NT15 -v $ARG1$ $ARG2$

That is the old password I will add the new one there then restart the nagios server. I will let you know. I remember doing this before just couldn't remember where it was done at.

Thanks
