But I have following queries, I will be thankful if somebody can clarify them. 1) Since the SNMP4J-AgentX is licensed under GPL as well as commercial license. What is the difference between them? 2) Just to confirm that the SNMP4J-AgentX provide all the API provided by the SNMP4J-Agent. 3) Final query not exactly related to SNMP4J, is it possible to create an agent which will act as SNMP V2/V3 agent if there is no existing Master Agent and else act as the Subagent.

What is the difference between them? When using SNMP4J-AgentX licensed under the GPL, then you will have to make all your code that is directly related (i.e., using the API) also available under the GPL. With the commercial license you do not need to make your own code open source. For more details you should compare the both license agreements. > 2) Just to confirm that the SNMP4J-AgentX provide all the API provided > by the SNMP4J-Agent. Yes, SNMP4J-AgentX is build on top of SNMP4J-Agent and thus includes all its features. > 3) Final query not exactly related to SNMP4J, is it possible to create > an agent which will act as SNMP V2/V3 agent if there is no existing > Master Agent and else act as the Subagent. Yes, of course.

If I use snmpv3 without encryption all works fine. Also if I use the get command with encryption it works fine. But if I try to set a snmp variable to something else, there is no result. Here's my source: public String setV3(OID oid,Variable variable) throws IOException, NoResponseException { TransportMapping transport = new DefaultUdpTransportMapping(); Snmp snmp = new Snmp(transport); USM usm = new USM( SecurityProtocols.getInstance(), new OctetString(MPv3.createLocalEngineID()), 0 ); SecurityModels.getInstance().addSecurityModel(usm); snmp.getUSM().addUser(new OctetString(snmpV3User), new UsmUser(new OctetString(snmpV3User), AuthMD5.ID, new OctetString(snmpAuthPassphrase), PrivDES.ID, new OctetString(snmpPrivPassphrase))); transport.listen(); CommandResponder trapPrinter = new CommandResponder() { public synchronized void processPdu(CommandResponderEvent e) { PDU command = e.getPDU(); if (command != null) { } } }; snmp.addCommandResponder(trapPrinter); // setting up target target.setRetries(retries); target.setTimeout(timeout); target.setVersion(version); ((UserTarget)target).setSecurityLevel(SecurityLevel.AUTH_PRIV); ((UserTarget)target).setSecurityName(new OctetString(getSnmpV3User())); //Create var Binding VariableBinding vb = new VariableBinding(oid); vb.setVariable(variable); // creating PDU PDU pdu = new ScopedPDU(); pdu.add(vb); pdu.setType(PDU.SET); System.out.println(pdu); ResponseEvent response = snmp.set(pdu,target); System.out.println(response.getUserObject()); if(response == null){ throw new NoResponseException(); } return response.getRequest().toString(); } NOTE: If I don't use encryption I set the SecurityLevel to NOAUTH_NOPRIV I have checked the encryption pass phrases and searched for a possibility to solve the problem. But I couldn't find anything. I hope you can help me.
