Hello, I am running snmpd on a Windows PC and am trying to get SNMP V3 traps/informs to work. No issues with V2c Traps/Informs. net-snmp-5.8
I created the V3 users and it is retrievable from the usmUserTable. Name/OID: usmUserSecurityName.7.128.0.41.136.120.120.136.10.76.72.97.121.101.115.84.101.115.116; Value (OctetString): LHayesTest Name/OID: usmUserCloneFrom.7.128.0.41.136.120.120.136.10.76.72.97.121.101.115.84.101.115.116; Value (OID): .0.0 Name/OID: usmUserAuthProtocol.7.128.0.41.136.120.120.136.10.76.72.97.121.101.115.84.101.115.116; Value (OID): usmHMACMD5AuthProtocol Name/OID: usmUserAuthKeyChange.7.128.0.41.136.120.120.136.10.76.72.97.121.101.115.84.101.115.116; Value (OctetString): Name/OID: usmUserOwnAuthKeyChange.7.128.0.41.136.120.120.136.10.76.72.97.121.101.115.84.101.115.116; Value (OctetString): Name/OID: usmUserPrivProtocol.7.128.0.41.136.120.120.136.10.76.72.97.121.101.115.84.101.115.116; Value (OID): usmDESPrivProtocol Name/OID: usmUserPrivKeyChange.7.128.0.41.136.120.120.136.10.76.72.97.121.101.115.84.101.115.116; Value (OctetString): Name/OID: usmUserOwnPrivKeyChange.7.128.0.41.136.120.120.136.10.76.72.97.121.101.115.84.101.115.116; Value (OctetString): Name/OID: usmUserPublic.7.128.0.41.136.120.120.136.10.76.72.97.121.101.115.84.101.115.116; Value (OctetString): Name/OID: usmUserStorageType.7.128.0.41.136.120.120.136.10.76.72.97.121.101.115.84.101.115.116; Value (Integer): readOnly (5) Name/OID: usmUserStatus.7.128.0.41.136.120.120.136.10.76.72.97.121.101.115.84.101.115.116; Value (Integer): active (1) When I generate a condition that should trigger an Inform I see the following in the log of snmpd. usm: USM processing has begun (offset 113) usm: getting user LHayesTest usm: match on user LHayesTest usm: Failed to find engine data. usm: Signing failed. snmpd: send_trap: USM authentication failure (incorrect password or key) My engineBoots always has a value of 1 in the persist file snmpd.conf. Not sure if this is somehow causing an issue, but worth noting as I have read engineBoots of 1 might affect V3. The process I use to manage the daemon: 1) write trap/inform directives in a snmpd.local.conf 2) kill snmpd, remove all usmUser directives 3) add createUser directives 4) start snmpd again. So can anyone help with why I am seeing the 'Failed to find engine data' which I think is the cause of the inform not being sent out? Or other suggestions. Thanks in advance Larry Hayes
