[SNMP4J] Asynchronous Request Not Working with SNMP v3

[lalit patel]

Hi
I wonder why the following code is not working?
........
.......
try{
        TransportMapping transport = new DefaultUdpTransportMapping();
        Snmp snmp= new Snmp(transport);
        USM usm = new USM(SecurityProtocols.getInstance(),
                     new OctetString(MPv3.createLocalEngineID()), 0);
        SecurityModels.getInstance().addSecurityModel(usm);
        //transport.listen();
        // add user to the USM
       snmp.getUSM().addUser(new OctetString(AdminName),
                         new UsmUser(new OctetString(AdminName),
                                     AuthMD5.ID,
                                     new OctetString(Password),
                                     PrivDES.ID,
                                     new OctetString(Password)));
            // create the target
                  UserTarget target[] = new UserTarget[NoOfSite];
                  for(int i=0;i<NoOfSite;i++)
                  {

                     target[i] = new UserTarget();

                     }
           for(int i=0;i<NoOfSite;i++)
                {
                   target[i].setAddress(targetAddress[i]);
                   target[i].setRetries(2);
                   target[i].setTimeout(5000);
                   target[i].setVersion(SnmpConstants.version3);
                   target[i].setSecurityLevel(SecurityLevel.AUTH_PRIV);
                   target[i].setSecurityName(new OctetString(AdminName));
                 }
             ScopedPDU pdu = new ScopedPDU();

             pdu.add(new VariableBinding(new OID("1.3.6.1.2.1.1.3")));//
sysuptime
              pdu.setType(PDU.GET);
             //transport.listen();
              snmp.listen();

             ResponseListener listener = new ResponseListener() {
        public void onResponse(ResponseEvent event) {

        //((Snmp)event.getSource()).cancel(event.getRequest(), this);
        if (event.getResponse() == null) {

            //System.out.println("Request "+request+" timed out");
            System.out.println("Sorry Request Time out");

        }
        else {
            System.out.println("Hello lalit you got response!");
            //System.out.println("Received response "+response+"\n on
request "+request);
            System.out.println(event.getResponse().toString());
              }
          }
 };

     for(int i=0;i<NoOfSite;i++)
     {
         snmp.send(pdu, target[i], null, listener); //send  all request
     }
        }
          catch (IOException e) {
           System.err.println("Caught IOException: "+ e.getMessage());
        }
    }
  }


Any suggestion ??


thanks
