nrpe error

[netaccs]

Hello.

Sorry if this is not the right place for that kind of question.

I have installed Freebsd9 with nrpe 2.15.
In messages I have that kind of errors:

34 is Nagios Server. 77 and 79 are Kaspersky AV server working under Windows OS.

In nrpe.cfg I have:
allowed_hosts=192.168.1.34,127.0.0.1,192.168.77,192.168.1.79

When remove 77 and 79, messages are changed to:
allowed_hosts=192.168.1.34,127.0.0.1

What could be the problem ?

Hello, @netaccs.

allowed_hosts=192.168.1.34,127.0.0.1,192.168.77,192.168.1.79

You missed 1 in 192.168.1.77.

Are you running NRPE as a standalone daemon or under xinetd? You may need to add the allowed ip's to /etc/xinetd.d/nrpe.cfg
In that config file separate IP addresses with spaces, not with commas.

Make sure to restart nrpe with:

Code: Select all

service nagios restart
or 
service xinetd restart

I am Sorry for delay.
I am using nrpe daemon on computers.

It is somehow connected with kaspersky antivirus server. I have two server with KAV installed on it.
And I have many
nrpe[85804]: Host 192.168.1.79 is not allowed to talk to us!
nrpe[85985]: Host 192.168.1.77 is not allowed to talk to us!

What could be the conflict?

Welcome back, @netaccs. Here's what you need to do:

You need to add the allowed ip's to /etc/xinetd.d/nrpe.cfg
In that config file separate IP addresses with spaces, no commas.

Then:

Code: Select all

service xinetd restart
