Nagios-Nrpe-Server Won't Start

I'm trying to setup a new Nagios server and point the various remote servers to it. I'm having issues with the nagios-nrpe-server not starting/restarting on a particular server running Ubuntu 11.04 I've tried uninstalling/reinstalling nagios/nrpe numerous times without success. The confusing part is the old Nagios monitoring server shows this server/services as being up, regardless of what I do to the nagios-nrpe-server service. Only when I remove the nagios-plugins do I see a change on the old monitoring server.
I found two bugs relating to this issue, but both solutions don't appear to resolve the problem.

Any insight would be much appreciated. Thanks!

cs_nagcc,
Did you install NRPE from source or using APT?

Yancy,
I've actually tried both ways in trying to resolve the issue. Is there a more preferred/updated way?

cs_nagcc,
installing from your distributions repository is usually preferred (unless the repo version is buggy).
can you check if the service is currently running
Code: Select all
sudo service --status-all | grep nrpe
If the service is currently running, is it listening on a port?
if these two items work, are you able to run this from Nagios
Code: Select all
/usr/local/nagios/libexec/nrpe -h "ip address of client"
regards,
-Yancy

The result of the first command shows that the nagios-nrpe-server is not running:
[ ? ] irqbalance
[ ? ] killprocs
[ ? ] module-init-tools
[ - ] nagios-nrpe-server
[ ? ] network-interface
[ ? ] network-interface-security
[ ? ] networking
[ ? ] ondemand
If I try to start it, I receive a message stating it is started, but the results above are still the same.
When I try to run the check_nrpe command from the new Nagios server to the remote host, I get "Could not complete SSL handshake". I am assuming this is related to the nagios-nrpe-server not running.
If I run the same check from the old Nagios server, I receive the expected NRPE version.
Thank you for your help Yancy!

Do you have your new server's IP in the allowed_hosts section of NRPE.cfg? On the server you are attempting to contact?

Yes, the new Nagios server's IP address was added to the NRPE.cfg file. I switched about 25-30 other servers over to our new Nagios monitoring system with no issues whatsoever, but this one just will not cooperate.

Can you post a copy of the NRPE.cfg file on the remote host? If you are initializing using xinetd, also post the /etc/xinet.d./nrpe file. Thanks!

You have multiple uncommented include statements at the bottom of the file, any chance that there are some other setting in those files?
Code: Select all
# local configuration:
# if you'd prefer, you can instead place directives here
include=/etc/nagios/nrpe_local.cfg
#
# you can place your config snipplets into nrpe.d/
include_dir=/etc/nagios/nrpe.d/
