FYI: /var/log/system.log on the client shows:
Mar 18 16:08:07 shu xinetd[29066]: START: nrpe pid=557 from=10.1.1.170
Mar 18 16:08:07 shu nrpe[557]: Error: NRPE daemon cannot be run as
user/group root!
whether I do the default test (with SSL) or use the -n flag to test w/o
SSL. The odd thing is that the nrpe config in /etc/xinetd.d is set to
run as nobody:nobody and /etc/nagios/nrpe.cfg is owned by nobody:nobody.
Only /usr/local/sbin/nrpe is owned by root (as it should be), but is
also set to 755 perms. I've compared to a Linux box I have with NRPE and
xinetd working properly and the permissions are identical.
I'm stumped...

I have two Mac OS X servers, one running 10.3, the other running 10.4.
Neither can be upgraded to 10.5 due to third party s/w constraints.
Both are PPC based XServe's.
Trying to compile nrpe with:
./configure --sysconfdir=/etc/nagios --enable-ssl
Initially, I got the "cannot find ssl libraries" error:
~
checking for SSL headers... SSL headers found in /usr/local/ssl
checking for SSL libraries... configure: error: Cannot find ssl
libraries
I downloaded the latest openssl and built it with:
./config --prefix=/usr/local shared --openssldir=/usr/local/openssl
make
make test
make install
I then had to edit ~/src/nrpe/configure and change the reference from
libssl.so to libssl.dylib
After that, nrpe compiled cleanly and I was able to move
~src/nrpe/src/nrpe to /usr/local/sbin and start xinetd up. I've
confirmed that port 5666 is open and xinetd is running:
/usr/local/src/nrpe-2.12/src root# ps waux|grep xinet|grep -v
greproot 29066 0.0 -0.0 27484 308 ?? Ss 3:53PM
0:00.02 /usr/sbin/xinetd -pidfile /var/run/xinetd.pid -stayalive
/usr/local/src/nrpe-2.12/src root# netstat -an|grep 5666tcp4
0 0 *.5666 *.* LISTEN
However, when connecting from the remote server, I get:
/usr/local/nagios/libexec/check_nrpe -H host.mydomain.org
CHECK_NRPE: Error - Could not complete SSL handshake.
The same test but w/o SSL gives yields:
[nag...@nephilim src]$ /usr/local/nagios/libexec/check_nrpe -n -H
host.mydomain.org
CHECK_NRPE: Received 0 bytes from daemon. Check the remote server
logs for error messages.
So two questions:
1) I'm a UNIX guy, but obviously Mac's are A) different and B) a tad
different being BSD-based. So what's the proper way to stop/restart
the xinetd daemon?
2) Any thoughts on SSL handshake error? I've googled it, but I'm not
getting very far.
Anyone have a step-by-step for compiling nagios plugins and NRPE from
source on OS X 10.x (specifically 10.3 and 10.4)? I'm using NRPE for
all other internal hosts, so I prefer to use it for the Mac's too. I
know I could do it via check_by_ssh and get around this, but I prefer
to use NRPE if I can.
