[SNMP4J] Problem:Unable to receive a response

[Mark Chan]

Hi, 

Below is the test script that i used to try and run snmp. However it
seems i am unable to get a response form the specified machine. Any
help to my problem is greatly appreciated.


public class testingSNMP{
	
	public static void main(String[] args) throws IOException,
InterruptedException{
		
		
		Address targetAddress = GenericAddress.parse("udp:192.168.0.126/161");
	
		CommunityTarget target = new CommunityTarget();
		target.setCommunity(new OctetString("public"));
		target.setAddress(targetAddress);
		target.setVersion(SnmpConstants.version1);
		target.setRetries(1);
//		 set timeout to 500 milliseconds -> 2*500ms = 1s total timeout
		target.setTimeout(20000);

		target.setVersion(SnmpConstants.version1);
		Snmp snmp = new Snmp(new DefaultUdpTransportMapping());
		PDU request = new PDU();
		request.add(new VariableBinding(new OID(".1.3.6.1.2.1.1.3")));
		request.setType(PDU.GETNEXT);
		
		ResponseListener listener = new ResponseListener() {
				public void onResponse(ResponseEvent event) {
						PDU response = event.getResponse();
						PDU request = event.getRequest();
							if (response == null) {
								System.out.println("Request "+request+" timed out");
							}else{
								System.out.println("Received response "+response+" on request "+
													request);
							}
				}
		};
	
		
		snmp.send(request, target);
		Thread.sleep(500);
	
	}
	
}
