Network Monitoring - Communication between Nagios & NRPE
Hello,
The communication between nagios and nrpe agent in the monitored host, can be without SSL? The problem is that I have 2 different versions of debian running on the machines and there are problems related to the libssl-dev package! Thanks
I already forgot the idea to use SSL. Now i have installed both nagios and nrpe plugin with the --disable-ssl option. I am following the NRPE official documentation but in this step:
ii. Test communication with the NRPE daemon
Make sure the check_nrpe plugin can talk to the NRPE daemon on the remote host. Replace "192.168.0.1" in the
command below with the IP address of the remote host that has NRPE installed.
/usr/local/nagios/libexec/check_nrpe -H 192.168.0.1
You should get a string back that tells you what version of NRPE is installed on the remote host, like this:
NRPE v2.8
I get an error: CHECK_NRPE: Received 0 bytes from daemon. Check the remote server logs for error messages.
I think the problem is in the connection between the server and the remote machine.. But i don't know how to solve this!
If i try 'telnet 192.168.100.1 5666' in the Monitoring machine:
Trying 192.168.100.1...
Connected to 192.168.100.1.
Escape character is '^]'.
Connection closed by foreign host.
