Hi all, I am very new to Nagios, but figure I know my way around it as it has taken me nearly a week to get it working (of sorts). I have a problem with the fact that all my hosts say that they are down and the service for the host (ping) says status unknown. In the status information column it says '/bin/ping -n -U -c 1 10.234.4.21' for the host and '/bin/ping -n -U -c 5 10.234.4.21' for the service. This I am guessing is correct as the host check does a 1 count ping and the service takes 5 and determins if the thing is up or not?!?! The host is deinately there and if I run the said commands in the command line it returns OK. Running Nagios 1.1 on Mandrake 9.1, The host is on the same network vlan as the server as I thought it would be better to begin at the beginning. Can anyone help please.
