user to the USM snmp.getUSM().addUser(new OctetString("MD5DES"), new UsmUser(new OctetString("MD5DES"), AuthMD5.ID, new OctetString("MD5DESUserAuthPassword"), PrivDES.ID, new OctetString("MD5DESUserPrivPassword"))); // 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("MD5DES")); // create the PDU PDU pdu = new ScopedPDU(); pdu.add(new VariableBinding(new OID("1.3.6"))); pdu.setType(PDU.GETNEXT); // send the PDU ResponseEvent response = snmp.send(pdu, target); // extract the response PDU (could be null if timed out) PDU responsePDU = response.getResponse(); // extract the address used by the agent to send the response: Address peerAddress = response.getPeerAddress();

An asynchronous SNMPv1 request is sent by the following code:

 // setting up target CommunityTarget target = new CommunityTarget(); target.setCommunity(new OctetString("public")); target.setAddress(targetAddress); target.setRetries(2); target.setTimeout(1500); target.setVersion(SnmpConstants.version1); // creating PDU PDU pdu = new PDU(); pdu.add(new VariableBinding(new OID(new int[] {1,3,6,1,2,1,1,1}))); pdu.add(new VariableBinding(new OID(new int[] {1,3,6,1,2,1,1,2}))); pdu.setType(PDU.GETNEXT); // sending request ResponseListener listener = new ResponseListener() { public void onResponse(ResponseEvent event) { // Always cancel async request when response has been received // otherwise a memory leak is created! Not canceling a request // immediately can be useful when sending a request to a broadcast // address. ((Snmp)event.getSource()).cancel(event.getRequest(), this); System.out.println("Received response PDU is: "+event.getResponse()); } }; snmp.sendPDU(pdu, target, null, listener);

Traps (notifications) and other SNMP PDUs can be received by adding the folling code to the first code snippet above:

 CommandResponder trapPrinter = new CommandResponder() { public synchronized void processPdu(CommandResponderEvent e) { PDU command = e.getPDU(); if (command != null) { System.out.println(command.toString()); } } }; snmp.addCommandResponder(trapPrinter);
