Hi,
I tried creating an SNMP agent
The following is the listener code
Snmp snmp = new Snmp( new MessageDispatcherImpl() );
// Add message processing models to be supported
snmp.getMessageDispatcher().addMessageProcessingModel( new
MPv1() );
snmp.getMessageDispatcher().addMessageProcessingModel( new
MPv2c() );
snmp.getMessageDispatcher().addMessageProcessingModel( new
MPv3() );
engineId = new
OctetString(((MPv3)snmp.getMessageProcessingModel(MessageProcessingModel.MPv3)
).getLocalEngineID());
USM usm = new USM(SecurityProtocols.getInstance(), engineId ,
0);
SecurityModels.getInstance().addSecurityModel(usm);
SecurityProtocols.getInstance().addDefaultProtocols();
snmp.addTransportMapping( transport );
snmp.addCommandResponder( subAgent );
UsmUser user = new UsmUser(new OctetString("MD5DES"),AuthMD5.ID,
new
OctetString("MD5DESUserAuthPassword"),
PrivDES.ID,
new
OctetString("MD5DESUserPrivPassword"));
snmp.getUSM().addUser(new OctetString("MD5DES"), user);
subAgent.setSnmp( snmp );
if( ! transport.isListening() )
transport.listen();
Send code
ScopedPDU pdu3 = new ScopedPDU();
pdu3.setType(PDU.GET);
pdu3.setMaxRepetitions(50);
// Get ifNumber only once
pdu3.setNonRepeaters(1);
// set context non-default context (default context does not need
to be set)
pdu3.setContextName(new OctetString("contextA"));
pdu3.setContextEngineID(new
OctetString(((MPv3)snmp.getMessageProcessingModel(MessageProcessingModel.MPv3)).getLocalEngineID()));
// Added a few varbinds
UserTarget target = new UserTarget();
target.setAddress(targetq.getAddress());
target.setRetries(1);
target.setTimeout(5000);
target.setVersion(SnmpConstants.version3);
target.setSecurityLevel(SecurityLevel.AUTH_PRIV);
target.setSecurityName(new OctetString("MD5DES"));
snmp.send(pdu3, target );
When i enabled trace on snmp4j i got the following information
