CHECK_NRPE: Error - Could not complete SSL handshake.

[John12]

hi..

I m running nagiosxi Virtual machine with static IP via proxypass in my host. currently i am in trial mode but will purchase the licence once my problem get solve. :-/. I can access Nagiosxi from any external IP. I need to monitor my host from nagiosxi VM running in vmware. I unable to install nagiosxi in my server directly because nagiosxi not accepting Mysql root password .. even though i given correct one. it ask password again and again.. first the password given are visible.. if i press spacebar and proceed it again ask password. this time password are nonvisible.. but both way it not accepting. So i decided to go with VMware nagiosxi VM to monitor my centos 5.7 server.

I ran setup to add host in nagiosxi VM and added my host. IP: 1.1.1.1 . downloaded agent and installed in server. but i am getting CHECK_NRPE: Error - Could not complete SSL handshake. for all services expect "ping" ..

This is my /etc/xinetd.d/nrpe in host.

# default: on
# description: NRPE (Nagios Remote Plugin Executor)
service nrpe
{
flags = REUSE
socket_type = stream
port = 5666
wait = no
user = nagios
group = nagios
server = /usr/local/nagios/bin/nrpe
server_args = -c /usr/local/nagios/etc/nrpe.cfg --inetd
log_on_failure += USERID
disable = no
only_from = 1.1.1.2 #This is my Nagios XI VM Static IP
}

Code: Select all

[root@u15830099 xinetd.d]# chkconfig --list nrpe
nrpe            on

Code: Select all

[root@u15830099 xinetd.d]# netstat -lpn |grep 5666

Code: Select all

[root@u15830099 xinetd.d]# /usr/local/nagios/libexec/check_nrpe -H 1.1.1.2
Connection refused or timed out

I don know whether The connection refused is because i m using proxypass to direct a subdomain to nagiosxi VM in my vhost.conf? If this is cause then wt i have to do...
Proxypass / http://1.1.1.2/
ProxypassReverse / http://1.1.1.2/

On my Nagios XI Virtual Machine /etc/xinetd.d/nrpe

# default: on
# description: NRPE (Nagios Remote Plugin Executor)
service nrpe
{
flags = REUSE
socket_type = stream
port = 5666

log_on_failure += USERID
disable = no
only_from = 1.1.1.2 #This is my Nagios XI VM Static IP
}

Code: Select all

[root@nagiosxi ~]# /usr/local/nagios/libexec/check_nrpe -H 1.1.1.1
CHECK_NRPE: Error -could not complete SSL handshake

pls assist me how to correct it. i am completely lost. I am always ready to provide any other info for your kind consideration.

Awaiting response patiently.
Jack.

Cal you run

Code: Select all

tail -f /var/log/messages

on the client machine to see what nrpe errors might be reporting.

Thanks

Any help. awainting ..

[scottwilkerson]

It looks like your server is making the connection from the IP 1.1.1.1

If this is a valid IP for the server, you will want to add 1.1.1.1 to the only_from address in /etc/xinetd.d/nrpe

[John12]

Thanks alot.. that really worked. my /etc/xinetd.d/nrpe in host is as allowed from = 127.0.0.1 <host ip> <nagios server ip>
Nrpe 2.12 return in my host and as well as in nagiosxi VM when i do check_nrpe.

I have added my host in NagiosXI server via "Run Monitoring wizard" . ALL configuration passes successfully but i m not able to see any service detail in service status window..

"No matching services found".

What i am doing wrong.. please assist.

Thanks,
John.
