Ok, what's the /etc/xinetd.d/nrpe file look like?

I am running nrpe under xinetd.

I did a netstat -a | grep 5666 and there was no output. I was returned to a
shell prompt.

Nrpe.cfg is located at /usr/local/nagios

Anything else?

Ok, take one giant step backwards.

How are you running nrpe?  As a daemon or xinetd/inetd?

Now do a netstat -a | grep 5666

What's the output?

Now, where is nrpe.cfg?

The messages log file had the following entries:

Server /usr/local/nagios/nrpe is not executable [line=10]

nrpe[26725]: Unable to open config file '//nrpe.cfg' for reading
Config file '//nrpe.cfg' contained errors, bailing out...

What gives?

check_disk? Or check)disk.  Not sure if you just made a typo on the command
back into the email.

Check the log on oneofxeon, probably in /var/log/messages to see what's
going
on.  That usually means that you don't have permission to connect (ala,
/etc/hosts.allow if you run under (x)inetd or the nrpe.cfg file if you
don't.

I entered in the following: 

./check_nrpe -H oneofxeon -p 5666 -c check)disk

and got the following:

CHECK_NRPE: Error receiving data from host.

Perhaps I gave you the wrong command..  lowercase c, instead of capital:

$ ./check_nrpe -H db1 -p 5666 -c check_disk_var

Here's what I entered:

./check_nrpe -H oneofxeon -p 5666 -C check_disk -w 80 -c 95

I got the same error message.....

I also tried 

./check_nrpe -H oneofxeon -p 5666 -C check_disk

and got the same result....

You have to specify -C check_disk

It's the same command in the square brackets:
command[check_users]=....

The command that I entered at the monitoring host was

./check_nrpe -H oneofxeon -p 5666 -C /usr/local/nagios/libexec/check_disk -w
80 -c 95

The result was INCORRECT COMMAND LINE ARGUMENTS SUPPLIED

What gives?

Try running the check_nrpe command from the monitoring host.

check_nrpe -H <host> -p <port> -C check_userrs

see if that gets you any further.

I noticed that -H and -p were added in the change from nrpe 1.5 to 1.6

Things got a little better since I sent out my e-mail. I am getting a
connection
to
to the remote client. Now I am getting an INCORRECT COMMAND LINE ARGUMENTS
SUPPLIED
error.

When I run the check from the command line, it comes out fine.

Here is the syntax of the nrpe.cfg file on the client:

command[check_users]=/usr/local/nagios/libexec/check_users 50 80
command[check_disk1]=/usr/local/nagios/libexec/check_disk 80 95 /dev/sda8
command[check_load]=/usr/local/nagios/libexec/check_load 15,10,5 30,25,20
command[check_procs]=/usr/local/nagios/libexec/check_procs 150 200

What is going on?

And running check_nrpe from the command line...?  Pass or fail...?
