SNMP4J Satz Fehler

Question

Ich Executing diesen Befehl DOS SNMP-Set von snmp4J:

snmpset -c privaten -v 2c 192.168.1.26 .1.3.6.1.4.1.991.100.5.19.3.0 u 1

Dies ist der Code:

public class SnmpSetExample { 

private static String ipAddress = "192.168.1.26"; 
private static String port = "161"; 
private static String sysContactOid = ".1.3.6.1.4.1.991.100.5.19.3.0"; 
private static int sysContactValue = 1; 
private static int snmpVersion = SnmpConstants.version2c; 
private static String community = "private"; 

public static void main(String[] args) throws Exception { 
    System.out.println("SNMP SET Demo"); 

    TransportMapping transport = new DefaultUdpTransportMapping(); 
    transport.listen(); 

    CommunityTarget comtarget = new CommunityTarget(); 
    comtarget.setCommunity(new OctetString(community)); 
    comtarget.setVersion(snmpVersion); 
    comtarget.setAddress(new UdpAddress(ipAddress + "/" + port)); 
    comtarget.setRetries(2); 
    comtarget.setTimeout(1000); 

    PDU pdu = new PDU(); 

    // Setting the Oid and Value for sysContact variable 
    OID oid = new OID(sysContactOid); 

    Variable var = new Integer32(sysContactValue); 
    VariableBinding varBind = new VariableBinding(oid, var); 
    pdu.add(varBind); 

    pdu.setType(PDU.SET); 
    pdu.setRequestID(new Integer32(1)); 

    // Create Snmp object for sending data to Agent 
    Snmp snmp = new Snmp(transport); 

    ResponseEvent response = snmp.set(pdu, comtarget); 

    if (response != null) { 
     System.out.println("\nResponse:\nGot Snmp Set Response from Agent"); 
     PDU responsePDU = response.getResponse(); 

     if (responsePDU != null) { 
      int errorStatus = responsePDU.getErrorStatus(); 
      int errorIndex = responsePDU.getErrorIndex(); 
      String errorStatusText = responsePDU.getErrorStatusText(); 

      if (errorStatus == PDU.noError) { 
       System.out.println("Snmp Set Response = " + responsePDU.getVariableBindings()); 
      } else { 
       System.out.println("Error: Request Failed"); 
       System.out.println("Error Status = " + errorStatus); 
       System.out.println("Error Index = " + errorIndex); 
       System.out.println("Error Status Text = " + errorStatusText); 
      } 
     } else { 
      System.out.println("Error: Response PDU is null"); 
     } 
    } else { 
     System.out.println("Error: Agent Timeout... "); 
    } 
    snmp.close(); 
} 

}

Aber mein Fehler Ergebnis ist:

... 
Response: 
Got Snmp Set Response from Agent 
Error: Response PDU is null 

Die PDU ist bereit für .SET. Jemand weiß, was in den Parametern oder im Code fehlt ?. Danke im Voraus.

Answer 1

in: Variable var = new Integer32 (sysContactValue);

Ändern Sie Gauge32 oder UnsignedInterger32 anstelle des Typs Integer32. Es ist notwendig, immer den Datentyp des zu sendenden Wertes zu überprüfen.
