You are either missing the perl package Crypt::SSLeay package on your new server or you have a different incompatible version of it: http://search.cpan.org/~nanis/Crypt-SSL ... /SSLeay.pm

As long as it has internet access you can run the following to download and install it if it is missing: cpan Crypt::SSLeay

You can use the following one-liner to determine what version of the package you have on each: It's also possible you are messing an OS dependency package... I can't remember what it's called exactly, something like libcrypt-devel.

ok, you nailed it, thank you so much....... fyi, after i got passed that, i got another error (below), but found a blog about inserting a line in the perl script, which fixed it.....so all is well, thanks again.

NEW LINE ADDED IN PERL SCRIPT
use Nagios::Plugin;
use File::Basename;
$ENV{PERL_LWP_SSL_VERIFY_HOSTNAME} = 0; <<<-------------- MUST BE AFTER "use File::Basename;"

Glad you found the solution ... I ran into the exact same error (having to set that environment variable) with the VMware plugin.
