check_nrpe SSL error

[Andrade, Leonardo F. Buonsanti de (BR - Sao Paulo)]

Hi all,

I'm getting SSL errors all the time i try to make check_nrpe 2.0..
first, in a redhat box with ssl 0.9.6 it did'nt work, maybe because of the
openssl version.
now in a redhat 9 box with ssl 0.9.7a i got errors again..
if i compile check_nrpe without ssl and try to use it with nrpe_nt i get
"could not complete ssl handshake" error
here's the redhat 9 error:

*** Compile finished ***

If the NRPE daemon and client compiled without any errors, you
can continue with installation.  The NRPE daemon and client
binaries are located in the src/ subdirectory.

 ** If this is your monitoring host **

     - Copy the check_nrpe client to the directory that
       contains your Nagios plugins.
     - Create a command definition in your Nagios config
       file for the NRPE client.  See the README file for
       more info on doing this.

 ** If this host will be running the NRPE daemon **

     - Copy the nrpe daemon to /usr/sbin, /usr/local/nagios
       or wherever you feel it fits best.
     - Copy the sample nrpe.cfg config file to /etc,
       /usr/local/nagios or wherever you feel it fits best.
     - Modify the /etc/services file and configure NRPE to
       run under inetd, xinetd, or as a standalone daemon.
       See the README file for more info on doing this.

at redhat 7.3 i got this:
