Nagios Support Forum

I have created a new Nagios Core server on Almalinux 9.
I have downloaded and installed 4.5.9 with the latest 2.4.11 plugins.
All work fine except for the CHECK_DNS plugin which returns

check_dns: error while loading shared libraries: libssl.so.1.1: cannot open shared object file:

Almalinux has OpenSSL 3.2.2 4 Jun 2024 installed so a much later version.

What is the solution please?
It seems the plugin is out of date? Am I able to obtain a newer version?

Any help much appreciated.

Thanks

Colin

Update openssl.

I'm running 3.2.2.4 and it is looking for 1.1 ... how will updating openssl help?
It's running the latest version.

Sorry, my bad reading comprehension is showing.

Hi,

You can execute for having more details about that shared library.

Which output are you getting?

Best regards

Getting this OpenSSL 3.2.2 4 Jun 2024 but gave up and have now reloaded with Almalinux 8 and all up and running.
