I have received the bellow error from my client system when I try to configure Nagios for client system

# ./configure
...
checking for SSL headers... configure: error: Cannot find ssl headers
...

#  yum provides */ssl.h


If you could not find the openssl-devel package, execute the below command to be installed
 
#  yum install openssl-devel

After that, i was able to configure and install the nrpe plugin on the client system.
