When you use the Linux Server Wizard, it assumes that the Linux NRPE agent that is provided by a link on the Wizard's page is installed in the remote server.
The Nagios provided agent is setup to install the NRPE agent on the remote system and configures it to use arguments but most 3rd party installers do not use arguments and that causes the errors you are receiving.
The simplest way it to use the NRPE Agent provided in the link below and install that on the remote system.
https://assets.nagios.com/downloads/nag ... ent.tar.gz
Here are the instructions for installing the agent.
https://assets.nagios.com/downloads/nag ... _Agent.pdf

Then, that will setup the remote agent to match the Linux Wizards Settings and the checks should work for you when you run the wizard.

Hi Team,

Thanks

You have mentioned in the OP that port 5666 was listening, but being this is in AWS, can you confirm that it is open in the EC2 security group your Ubuntu server is running?

This certainly will also be required as the security group act as another off-server firewall.

[ivp2015]

Yes it's open from our network, also i am able to telnet,

Port 5666

Thanks

I just looked over your /etc/xinetd.d/nrpe config previously posted and realized your only_from line has comma's in it, which is not correct, change this:

Code: Select all

only_from       = 127.0.0.1, 115.114.12.4, 182.74.168.35

to this

Code: Select all

only_from       = 127.0.0.1 115.114.12.4 182.74.168.35

Hi Team,

I have followed the instruction to install NRPE agent from Nagios document,

When we going to add new host in Nagios document and setup show in our portal,

And the ubuntu machine is on cloud also we have monitor other windows host they are working fine but on ubuntu we got error,

Please find bellow the out of given commands

_____________________________________________________________________

Code: Select all

cat /etc/xinetd.d/nrpe


root@ip-172-31-28-18:~# cat /etc/xinetd.d/nrpe
# 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       = 127.0.0.1, 115.114.12.4, 182.74.168.35

Hi Team,

I have done changes to

root@ip-172-31-28-18:~# cat /etc/xinetd.d/nrpe
# 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 = 127.0.0.1 115.114.12.4 182.74.168.35
}

and its still not working

[scottwilkerson]

for clarity, did you restart the xinetd service after making the changes?

[ivp2015]

Yes we have done the restart the nrpe xinetd services,

Thanks
