Support forum for Nagios Core, Nagios Plugins, NCPA, NRPE, NSCA, NDOUtils and more. Engage with the community of users including those using the open source solutions.
You would actually need to install the openssl-devel package, or at least thats how it's named in cent land. The plugins need the openssl sources to compile against them, not the binary. Then you actually should not need to specify the configure switch for where openssl is.
Nagios-Plugins maintainer exclusively, unless you have other C language bugs with open-source nagios projects, then I am happy to help! Please pm or use other communication to alert me to issues as I no longer track the forum.
