Hello Nagios Users, I'm attempting to setup a second nagios server up to do failover monitoring in case my primary nagios server goes down. Running into a odd problem in talking to the nrpe daemon on the master server..... When I run the following cmd prompt, nrpe does not allow me to connect from the new host even though it is specified in the master nagios server nrpe.cfg file. SLAVE$ /usr/lib/nagios/plugins/check_nrpe -H 10.10.10.41 -c check_load Connection refused by host However, when i run the same cmd for another host, it returns successfully. SLAVE:~$ /usr/lib/nagios/plugins/check_nrpe -H 10.10.10.43 -c check_load OK - load average: 0.00, 0.00, 0.00|load1=0.000;15.000;30.000;0; load5=0.000;10.000;25.000;0; load15=0.000;5.000;20.000;0; **Note thta the IP for the nagios failover server IS listed in the nrpe.cfg allowed_hosts directive and the nrpe daemon has been restarted. Any insight on this issue? I am running Nagios 2.11. Thanks, JJ
