[SNMP4J] Asynchronous Messages

[Marcel Bassuener]

Please,
can anyone help me.

I tried this method:
http://lists.agentpp.org/pipermail/snmp4j/2006-January/001002.html

Also I tried the Solution from the SNMP4J Wiki

But I alway receive only one Response.

This is the current Code:

DefaultUdpTransportMapping defaultTransport = new 
DefaultUdpTransportMapping();
         defaultTransport.setReceiveBufferSize(65535);
         TransportMapping transport = defaultTransport;


         Snmp snmp =  new Snmp(transport);

         OctetString localEngineID = new OctetString("Kaffee22");

         ((MPv3)snmp.getMessageProcessingModel(MPv3.ID)).
             setLocalEngineID(localEngineID.getValue());

         USM usm = new USM(SecurityProtocols.getInstance(),
                             localEngineID,
                             0);
         SecurityModels.getInstance().addSecurityModel(usm);

         UserTarget target = new UserTarget();
         target.setSecurityLevel(SecurityLevel.NOAUTH_NOPRIV);
         target.setSecurityName(new OctetString("Detect"));
         target.setVersion(SnmpConstants.version3);
         target.setAddress(new UdpAddress("192.168.11.255/161"));
         target.setRetries(1);
         target.setTimeout(3000);



         MessageDispatcher md = snmp.getMessageDispatcher();
         MultiThreadedMessageDispatcher test = new 
MultiThreadedMessageDispatcher(ThreadPool.create("Requester", 4),md);

         test.removeCommandResponder(snmp);
         test.addCommandResponder(this);
         test.addCommandResponder(snmp);

         snmp.listen();

         ScopedPDU request = new ScopedPDU();

         request.setType(PDU.GET);//createPDU(target);
         if (request.getType() == PDU.GETBULK) {
           request.setMaxRepetitions(50);
           request.setNonRepeaters(1);
         }
         request.add(new VariableBinding(new OID("1.3.6.1.2.1.1.1.0")));



         PduHandle reqHandle = test.sendPdu(transport, 
target.getAddress(), target.getVersion(),
                      SecurityModel.SECURITY_MODEL_USM, 
target.getSecurityName().getValue(),
                      SecurityLevel.NOAUTH_NOPRIV, request, true);

Thanks and Best regards
Marshall
