Nagios-Nrpe-Server Won't Start

[cs_nagcc]

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?

[yancy]

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?

Code: Select all

 sudo netstat -atnp 

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"

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?

[cs_nagcc]

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.

[slansing]

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!

[cs_nagcc]

I am not using xinetd. Attached is the file.

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/
