Hi Folks, I am having trouble with my Nagios server talking to the client through NRPE. The error is ... user is root: [root@XXXXXXXXXXXXX libexec]# ./check_nrpe -H dev -c check_disk1 Connection refused by host user is nagios: [root@XXXXXXXXXXXXX libexec]# su nagios [nagios@XXXXXXXXXXXXX libexec]$ ./check_nrpe -H dev -c check_disk1 Connection refused by host Also, I *cannot telnet* into the client as root or nagios. It just bumps me out with "Connection refused" We are using ssh for logins. I believe I have the nrpe.cfg on the client configged OK and the nagios.cfg on the server too. The command definitions look OK in client's nrpe.cfg (standard install) The services.cfg on the server (for check_users) looks like this: ############################################################################# define service{ use generic-service host_name Nagios.servername.com service_description USERS is_volatile 0 check_period 24x7 max_check_attempts 3 normal_check_interval 5 retry_check_interval 1 contact_groups slc-admins notification_interval 120 notifications_enabled 1 notification_period 24x7 notification_options w,c check_command check_nrpe!5666!check_users } ########################################## 1) What kind of network connectivity is required between the Nagios client and server? 2) In the Nagios client nrpe.cfg file: Should the server_address= be the IP address of the Nagios server? Not sure if the process needs to bind to it's own IP or the Nagios host. 3) Does the hosts.equiv need to be set up on the server/client? What about ~nagios/.rhosts? I have been searching over the docs to find answers to this stuff. Thanks, Joe McCaughan <hr size=1>Want to be your own boss?
