I am trying to configure snmptt to translate the snmp traps received and handle them as passive checks in icinga monitoring server as described here . after doing the changes to the snmptrapd.conf . I am trying to restart the service and I see authcommunity : command not found, traphandle : command not found . my understanding is the authcommunity and traphandle are just configuration directives which will tell snmptrapd about the community string to use and the traphandle script to be called. It would be helpful if someone can help me understand better. Thanks, sabs
