Is openssl installed? (you may have just grabbed the devel headers for compiling with ssl enabled, but you may not have actually installed openssl)

Package openssl-0.9.8e-26.el5_9.1.i686 already installed and latest version

should we be seeing that w/in the running services?

[root@XenHost8 init.d]# which openssl
/usr/bin/openssl
[root@XenHost8 init.d]#

Well ssl is there. It does not need to run as a daemon as it is a shared lib. Lets check what libs you have:

Also run these following commands and post the output:

find / -name libssl*

Well, looks like the check_nrpe binary I had you grab from the XI server will not work with the libraries on this system. Looks like you may have to build and install the nagios-plugins on this xen box.

do you have any recomendations/simple methods of how this is completed?


Thanks

Unpack the tarball from sourceforge and do what you normally would to build a package: But as this server's repos have been a bit wonky, expect issues and be surprised if all goes well.
