We'll also forward this to the list. Sorry for top posting, Blackberry and all.
And what do you get for check_nrpe --version?
I'm not positive right now, but I believe if you use an older check_nrpe with a newer nrpe (or vice versa) it won't work, something about the ssl-enabled nrpe and the older check not expecting it.
Also try turning on debug in your nrpe.cfg and running a few checks, then looking at the output in the log. Also, I'm not absolutely positive, but I believe there's a check_nrpe --verbose, which may show more of what is returned.
Oh, and search the docs for that error, should be more info there.
Usually with (No Output) errors it tends to be permissions, paths, or commands.

Subject: [Nagios-users] ===NRPE: Unable to read output
Hi Folks,
I am setting up Nagios with my first client. This is the output
I get when I execute the
command from the command line from the Nagios host is
"NRPE: Unable to read output "
It also shows up in the nagios.log.
The command line exec is:
./check_nrpe -H 83556-dev.slc.com -c check_total_procs
I have nrpe running on the client:
nagios 25998 1 0 Apr10 ? 00:00:05
/usr/local/nagios/libexec/nrpe -c /usr/local/nagios/nrpe.cfg -d
I am running xinetd and the service definitions on the client
are in /usr/local/nagios/etc/nrpe.cfg:
command[check_users]=/usr/local/nagios/libexec/check_users -w 5
-c 10
command[check_load]=/usr/local/nagios/libexec/check_load -w
15,10,5 -c 30,25,20
command[check_disk1]=/usr/local/nagios/libexec/check_disk -w 20
-c 10 -p /dev/hda3
command[check_disk2]=/usr/local/nagios/libexec/check_disk -w 20
-c 10 -p /dev/hda2
command[check_zombie_procs]=/usr/local/nagios/libexec/check_procs -w 5
-c 10 -s Z
command[check_total_procs]=/usr/local/nagios/libexec/check_procs
-w 150 -c 200
Why am I getting this error?
Thanks, --Joe McCaughan
Joe,
This might be a dumb question, but does the directory
/usr/local/nagios/libexec/ exist on the client (83556-dev.slc.com)?
Can you run /usr/local/nagios/libexec/check_procs -w 150 -c 200 as the
NAGIOS user and see a return?
What version nrpe & check_nrpe?
