We are unable to telnet the client machine on port 5666 from Nagios production server.
[Nagios Production server ~]$ telnet aeafnxweb01 5666
Trying 10.210.1.5...
telnet: connect to address 10.210.1.5: Connection refused
[[Nagios Production server ~]$
Services are in critical state with the following status information.
(No output on stdout) stderr: connect to address 10.110.2.5 port 5666: Connection refused
However, the server is up.
Is this because of we are uanble to telnet on 5666 that nrpe is not starting?
