These should work, provided your server has the necessary SSL libraries.
There are two possibilities --
1. You compiled the nrpe agent without SSL support (I have had to do this
under AIX)
2. It is compiled with SSL support, but it doesn't have the libraries
available (I occasionally have this under Solaris)

In both cases, you can work without ssl by using -n as an option to BOTH
nrpe and check_nrpe.  Why this is not documented, I don't know.

If it is (2), then install the SSL libraries and it should work.

Try running nrpe -I -c ... from the command line, and see if it produces any
helpful error messages like 'libraries not found', or if nrpe -v tells you
'SSL available' or not.
