Hi Frank,I recently upgraded to snmp4j 2.5.0 and snmp4j agent v2.5.0. There’s a bugfix in SNMP4J v2.5.0 which causes a Null Pointer Exception when we use the MOSubtreeProxy in SNMP4J-Agent v2.5.0
http://www.snmp4j.org/CHANGES.txt * Fixed [SFJ-121]: DefaultPDUFactory.createPDU does not set contextName and contextEngineID on ScopedPDU instances. The MOSubtreeProxy class needs to set (or initialize) the contextEngineID & contextEngineName in the DefaultPDUFactory inside its constructor. Currently when the DefaultPDUFactory.applyContextInfoToScopedPDU() is called via DefaultPDUFactory.createPDU(), both fields are NULL. 22767 [DefaultUDPTransportMapping_192.168.1.90/161] DEBUG org.snmp4j.agent.mo.snmp.VacmMIB - Access allowed for view 'fullReadView2' by subtree 1.3 for OID 1.3.6.1.2.1.1.1.0 java.lang.NullPointerException: Context engine ID must not be null at org.snmp4j.ScopedPDU.setContextEngineID(ScopedPDU.java:69) at org.snmp4j.util.DefaultPDUFactory.applyContextInfoToScopedPDU(DefaultPDUFactory.java:114) at org.snmp4j.util.DefaultPDUFactory.createPDU(DefaultPDUFactory.java:99) at org.snmp4j.agent.mo.snmp4j.MOSubtreeProxy.get(MOSubtreeProxy.java:139) at org.snmp4j.agent.CommandProcessor$GetHandler.processPdu(CommandProcessor.java:1074) at org.snmp4j.agent.CommandProcessor$GetHandler.processPdu(CommandProcessor.java:1041) at org.snmp4j.agent.CommandProcessor.processRequest(CommandProcessor.java:422) at org.snmp4j.agent.CommandProcessor.processRequest(CommandProcessor.java:384) at org.snmp4j.agent.CommandProcessor.dispatchCommand(CommandProcessor.java:340) at org.snmp4j.agent.CommandProcessor$Command.run(CommandProcessor.java:560) at org.snmp4j.agent.CommandProcessor.processPdu(CommandProcessor.java:163) at com.mibadapter.snmpagent.Processor.processPdu(Processor.java:73) at org.snmp4j.MessageDispatcherImpl.fireProcessPdu(MessageDispatcherImpl.java:689) at org.snmp4j.MessageDispatcherImpl.dispatchMessage(MessageDispatcherImpl.java:308) at org.snmp4j.MessageDispatcherImpl.processMessage(MessageDispatcherImpl.java:385) at org.snmp4j.MessageDispatcherImpl.processMessage(MessageDispatcherImpl.java:345) at org.snmp4j.transport.AbstractTransportMapping.fireProcessMessage(AbstractTransportMapping.java:76) at org.snmp4j.transport.DefaultUdpTransportMapping$ListenThread.run(DefaultUdpTransportMapping.java:423) at java.lang.Thread.run(Thread.java:745) 22773 [DefaultUDPTransportMapping_192.168.1.90/161] WARN org.snmp4j.agent.CommandProcessor - java.lang.NullPointerException: Context engine ID must not be null java.lang.Exception: Error 'General variable binding error' generated at: 1.3.6.1.2.1.1.1.0 = Null at org.snmp4j.agent.request.SnmpRequest$SnmpSubRequest.requestStatusChanged(SnmpRequest.java:621) at org.snmp4j.agent.request.RequestStatus.fireRequestStatusChanged(RequestStatus.java:89) at org.snmp4j.agent.request.RequestStatus.setErrorStatus(RequestStatus.java:52) at org.snmp4j.agent.CommandProcessor$GetHandler.processPdu(CommandProcessor.java:1087) at org.snmp4j.agent.CommandProcessor$GetHandler.processPdu(CommandProcessor.java:1041) at org.snmp4j.agent.CommandProcessor.processRequest(CommandProcessor.java:422) at org.snmp4j.agent.CommandProcessor.processRequest(CommandProcessor.java:384) at org.snmp4j.agent.CommandProcessor.dispatchCommand(CommandProcessor.java:340) at org.snmp4j.agent.CommandProcessor$Command.run(CommandProcessor.java:560) at org.snmp4j.agent.CommandProcessor.processPdu(CommandProcessor.java:163) at com.mibadapter.snmpagent.Processor.processPdu(Processor.java:73) at org.snmp4j.MessageDispatcherImpl.fireProcessPdu(MessageDispatcherImpl.java:689) at org.snmp4j.MessageDispatcherImpl.dispatchMessage(MessageDispatcherImpl.java:308) at org.snmp4j.MessageDispatcherImpl.processMessage(MessageDispatcherImpl.java:385) at org.snmp4j.MessageDispatcherImpl.processMessage(MessageDispatcherImpl.java:345) at org.snmp4j.transport.AbstractTransportMapping.fireProcessMessage(AbstractTransportMapping.java:76) at org.snmp4j.transport.DefaultUdpTransportMapping$ListenThread.run(DefaultUdpTransportMapping.java:423) at java.lang.Thread.run(Thread.java:745) ThanksRushik _______________________________________________ SNMP4J mailing list SNMP4J@agentpp.org https://oosnmp.net/mailman/listinfo/snmp4j
