Hi all. I am trying to send v2 informs and successfully retrieve the acknowledgements. I am using the following code for the receiver and the sender respectively.
Receiver: threadPool = ThreadPool.create("Trap", 2); dispatcher = new MultiThreadedMessageDispatcher(threadPool, new MessageDispatcherImpl()); listenAddress = GenericAddress.parse(System.getProperty("snmp4j.listenAddress", TRAP_LISTENER_UDP_ADDRESS)); snmp = new Snmp(dispatcher, new DefaultUdpTransportMapping()); snmp.addNotificationListener(listenAddress, this); snmp.getMessageDispatcher().addMessageProcessingModel(new MPv1()); snmp.getMessageDispatcher().addMessageProcessingModel(new MPv2c()); snmp.listen(); Sender: TransportMapping transport = new DefaultUdpTransportMapping(); Snmp snmp = new Snmp(transport); CommunityTarget target = new CommunityTarget(); target.setCommunity(this.communityString); target.setAddress(TRAP_LISTENER_UDP_ADDRESS); target.setRetries(1); target.setTimeout(1500); target.setMaxSizeRequestPDU(65535); target.setVersion(SnmpConstants.version2c); PDU pdu = new PDU(); pdu.setType(PDU.INFORM); List<VariableBinding> bindings = trap.getBindings(); sysUpTime = (System.currentTimeMillis() - this.startTime) / 10; pdu.add(new VariableBinding(SnmpConstants.sysUpTime, new TimeTicks(sysUpTime))); pdu.add(new VariableBinding(SnmpConstants.snmpTrapOID, trapOid)); for(VariableBinding binding : bindings) { pdu.add(binding); } ResponseEvent evt = snmp.inform(pdu, target); if(evt == null || evt.getResponse() == null) { System.err.println("Notification lost"); } else { System.out.println("Response: " + evt.getResponse()); } snmp.close(); The informs are successfully received on the receiver but no acknowledgment is sent back to the sender (or at least none is successfully retrieved by the sender). What am I doing wrong? Frankly, I am desperate and any help would be greatly appreciated. Thanks in advance.
