I have tried different settings no luck

As we suggested in the last tech post, did you try a different version of NSClient? .4.1 is old. .4.3 is the latest version in the .4 series, but they have moved on to .5.

If you continue to have trouble with NSClient, you might try NCPA, which we did actually write: https://exchange.nagios.org//directory/ ... PA/details

I will try on 4.3.77


NCPA never used before would need some instructions on that setup or examples of that

[dwhitfield]

Let us know how .4.3 goes.

As far as NCPA is concerned, https://assets.nagios.com/downloads/ncp ... g_NCPA.pdf should get you started, but if you have trouble with NCPA, you should open a new thread.

I put 4.3.77 on and now all the NRPE services I had working are not

They are all getting this

CHECK_NRPE: Error - Could not complete SSL handshake

NSCLIENT.INI not configured correctly my thoughts

[dwhitfield]

.4.3.77 is a nightly build, per https://www.nsclient.org/download/0.4.3/ but probably you ran into the following

In 0.4.3 we will no longer support the rather insecure regular NRPE!
You can still enable support but you have to do so (in the installer or using the command line mode).
So keep a heads up when you run the installer so you wont miss it.

from https://docs.nsclient.org/0.4.3/whatsnew/0.4.3.html

That said, please post your new nsclient.ini file.

[me@work55]

I am attaching the nsclient file that was created during the install

Also the one from 4.1.3

Please try changing the allowed hosts directive to an IP address instead of a DNS address:

Code: Select all

allowed hosts = X.X.X.X

Then restart the NSClient++ service and see if that works.

What does your nsclient.log show?

Are you just running this for testing?

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H X.X.X.X

I imported your config to mine, changed the DNS to my IP address and it worked properly so there may be something else going on.

[me@work55]

changed to ip address no change


from command

[root@anakin ~]# /usr/local/nagios/libexec/check_nrpe -H 132.238.5.25
CHECK_NRPE: Error - Could not complete SSL handshake.
[root@anakin ~]#

same error

[ssax]

What version of check_nrpe are you running:

Code: Select all

/usr/local/nagios/libexec/check_nrpe -V
