Trying to install the Linux agent on a box. I downloaded the agent from the gui and copied it over to the machine. It looks like it fails at the end with "can't read /etc/xinetd.d/nrpe: No such file or directory
Subcomponents installation failed - exiting" I checked and I do not have nrpe in in the xinetd.d directory. I tried searching on the forums but, did not see any thing like this one.

as the error mentions, check your system logs on the client machine and see what error is being reported.
to see if it's actually running on the client end use
netstat -an | grep 5666 - it's hard to say if the install finished properly. this documentation is really done well

Also, take a look at
https://assets.nagios.com/downloads/nag ... utions.pdf
Specifically, "VI. CHECK_NRPE: Received 0 Bytes From Daemon" on page 14.

I see in messages that the host is not allowed to talk to us!

Did you look at the document I sent? The first thing Section VI tells you to do is look at Section V. Did you do that? I'm not saying you didn't, you just didn't really give us any info. What exactly does the error message in the log say?
From the XI server, please run the following:
/usr/local/nagios/libexec/check_nrpe -H REMOTEIP -t 30 -c check_users -a '-w 5 -c 10'

This is what I get when I run this command below. I have read the document and I went in and added the host ip in the correct spot.
/usr/local/nagios/libexec/check_nrpe -H REMOTEIP -t 30 -c check_users -a '-w 5 -c 10'
CHECK_NRPE: Error - Could not complete SSL handshake.

when I run it locally I get:
CHECK_NRPE: Received 0 bytes from daemon. Check the remote server logs for error messages.

From Nagios, what's the output of
/usr/local/nagios/libexec/check_nrpe -H <remote host ip> -n?
On the remote server, what's the output of the following
Code: Select all
ls -la /usr/local/nagios/libexec/
ls -la /etc/xinetd.d/nrpe
netstat -an | grep 5666
ps -A | grep nrpe
ps -A | grep xinetd
If it exists, please post your /etc/xinetd.d/nrpe. If it does not exist, please let us know.
