[SNMP4J] SNMPv3 problem

[kenping liu]

Here is my codes:
   
  Address targetAddress = GenericAddress.parse("udp:10.23.6.128/161");
  TransportMapping transport = new DefaultUdpTransportMapping();
Snmp snmp = new Snmp(transport);
MPv3 mpv3 = (MPv3) snmp
    .getMessageProcessingModel(MessageProcessingModel.MPv3);
USM usm = new USM(SecurityProtocols.getInstance(), new OctetString(
    mpv3.createLocalEngineID()), 0);
SecurityModels.getInstance().addSecurityModel(usm);
transport.listen();
  // create the target
UserTarget target = new UserTarget();
target.setAddress(targetAddress);
target.setRetries(1);
target.setTimeout(5000);
target.setVersion(SnmpConstants.version3);
target.setSecurityLevel(SecurityLevel.AUTH_PRIV);
target.setSecurityName(new OctetString("myname"));
  // create the PDU
PDU pdu = new ScopedPDU();
pdu.add(new VariableBinding(new OID("1.3.6")));
pdu.setType(PDU.GETNEXT);
  // add the correct USM
snmp.getUSM().addUser(
    new OctetString("myname"),
    new UsmUser(new OctetString("myname"),
        AuthMD5.ID, new OctetString("aaaaaaaa"),
        PrivDES.ID, new OctetString("pppppppp")));
System.out.println(snmp.send(pdu, target).getResponse());
  // add the wrong USM
snmp.getUSM().updateUser(new UsmUserEntry(new OctetString("myname"),
    new UsmUser(new OctetString("myname"),
        AuthMD5.ID, new OctetString("xxxxxxxxxxx"),
        PrivDES.ID, new OctetString("pppppppp"))));
System.out.println(snmp.send(pdu, target).getResponse());
