Looks like the version of OpenSSL you have has dropped support for NRPE's DH key exchange.
https://github.com/NagiosEnterprises/nrpe/issues/93

You can bypass the issue by adding --with-need-dh=no to your configure command.

Or if you are not yet settled on NRPE, you could take a look at our newer agent, the Nagios Cross-Platform Agent.

Hello,

I have tried this and nrpe agent installed but the nrpe is unable to connect ssl error. So I have followed the below doc and installed the agent and is now connected.

But I am able to run arguments from the nagiosxi, with out arguments its working. I have set dont_blame=1, but the issue still exist.

Hi,

Glad your were able to get installed, have you setup the commands in nrpe.cfg with the argument option added, see:

NRPE - Configuring NRPE Commands To Accept Arguments

If so, can run one of the checks from the command line and post the output see we can review the error message? Thanks, Benjamin
