Hi, More on the inform issue in v3. I decided to use "snmptrap" and "snmptrapd" both running 5.5 and here are the details. I am not sure whether this is a config issue or there is some issue with inform in v3.
I have snmptrad running on the local host. I sent an inform message to the trap-server with the following command: $ sudo snmptrap -Ci -v 3 -e 0x80001f888085b94c4882d8bc4b -l noauth -u inter localhost 0 linkUp.0 t->local = t->remote = sock = 3 flags = 0x0 local_addr: 0.0.0.0 0.0.0.0 162 snmpinform: Timeout (Sub-id not found: (top) -> linkUp) Since snmptrap did not complain, it did send the message out and did not get response from snmptrapd. At the snmptrapd, with some debugs enabled, I am getting the following errors: snmp_parse: Parsed SNMPv3 message (secName:inter, secLevel:noAuthNoPriv): USM unknown engineID snmp_parse: Parsed SNMPv3 message (secName:inter, secLevel:noAuthNoPriv): USM unknown engineID snmp_parse: Parsed SNMPv3 message (secName:inter, secLevel:noAuthNoPriv): USM unknown security name (no such user exists) Following is my snmptrapd.conf file: " # snmptrapd.conf doNotRetainNotificationLogs yes #authCommunity log,execute,net public authCommunity log,execute public authUser log,execute inter createUser -e 0x80001f888085b94c4882d8bc4b inter traphandle .1.3.6.1.6.3.1.1.5.3 log " Is there anything missing in the config file? I am looking forward to any help on this issue.
