Nrpe Error Message

[Kaplan, Andrew H.]

I ran the ps auxww | grep npre command and nrpe did not appear.

If nrpe is not starting up, what is going on and what do I need to
do to get it up and running? I have followed the instructions to the
letter and there should be no reason for this to be happening.

When you ran:
/usr/local/nagios/nrpe -c /usr/local/nagios/nrpe.cfg --daemon

It should have returned you to a prompt.

Check ps auxww | grep nrpe and it should be running.  Then check netstat.  The
problem it appears is that nrpe isn't starting.

Once you get nrpe started, it should show up in netstat, then you can try
sending commands to it.

I ran netstat and I simply returned to the command prompt without any output
appearing on the screen.

I restarted xinetd via /etc/rc.d/init.d/xinetd restart and there were no
messages from nrpe in the log.

Finally, I ran the command line you suggested, but did not get any different
reaction. 

What now?

Sorry, I was at lunch. :)

Ok, check netstat again and see if it's bound.  You should have something
like
this:

$ netstat -a | grep 5666
tcp        0      0 *:5666                  *:*                     LISTEN

If you don't, then nrpe isn't running.

Restart xinetd.  If you get no messages from nrpe in the log and it still
isn't running, you need to try running it manually.

/usr/local/nagios/nrpe -c /usr/local/nagios/nrpe.cfg --daemon

Let me know what that does.

What does /var/log/messages show now?

And what's the ls -al output of /usr/local/nagios ?

Ok, go into /etc/xinetd.d/nrpe and modify it thus (only the server_args
changed), then make sure that /usr/local/nagios/nrpe is chmod 755
(-rwxr-xr-x):

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:

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.

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

Here's what I entered:

I also tried 

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

You have to specify -C check_disk

It's the same command in the square brackets:

The command that I entered at the monitoring host was

80 -c 95

The result was INCORRECT COMMAND LINE ARGUMENTS SUPPLIED

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_procs]=/usr/local/nagios/libexec/check_procs 150 200

What is going on?
