I wrote the following script and placed it into libexec. #!/bin/bash PREFIX=/usr/bin set `$PREFIX/radpwtst -trace 4 $USER1$/check_radius -s $1 -secret $2 -noacct -auth_port $3 -user $4 -password $5 -called_station_id $6 | tail -1` if [ $1 = OK ] ; then echo "OK" else echo "CRITICAL - No reply" fi Basically it sends a RADIUS authentication request to a radius server and will either come back with OK or No reply... I have tested the script and it works perfectly, but when I Integrate it with nagios, like this: define service{ use generic-service ; Name of service template to use host_name x.x.x.x service_description RADIUS is_volatile 0 check_period 24x7 max_check_attempts 3 normal_check_interval 3 retry_check_interval 1 contact_groups admins notification_interval 120 notification_period 24x7 notification_options u,c,r check_command check_radius!mysecret!1645!username!password!0198xxxxxx } My web interface in nagios shows a green light and says that everything is ok... even when the response is CRITICAL... How do I make nagios alarm when the script returns a CRITICAL error? Thanks in advance for any help you may offer.
