[Nagiosplug-help] NRPE, check_smtp, and Solaris = mysterious failure

[Florin Andrei]

I wrote a fake plugin, a shell wrapper that calls check_smtp then dumps 
its stdin and stderr to a debug file, then outputs some fake status to 
please nrpe. Looks like I nailed it:

# cat /tmp/debug
ld.so.1: check_smtp: fatal: libssl.so.0.9.8: open failed: No such file 
or directory

This also happens if I run check_smtp manually as the "nagios" user, via 
sudo. Apparently, it only sees that library if it's running as root, 
which is why check_smtp works fine manually as root, but fails when run 
via nrpe (or manually as non-root).
