Dear Friends,
currently I can send traps, but the source IP Address is always my
computer's IP Address, I wonder if it is possible to send a trap
from my computer with a different IP Address.
I have tried setAgentAddress(IpAddress) method but no luck.
below is my method
public void sendSnmpV1Trap()
{
try
{
//Create Transport Mapping
TransportMapping transport = new DefaultUdpTransportMapping();
transport.listen();
//Create Target
CommunityTarget comtarget = new CommunityTarget();
comtarget.setCommunity(new OctetString(community));
comtarget.setVersion(SnmpConstants.version1);
comtarget.setAddress(new UdpAddress("192.168.50.100"+ "/" + "162"));
comtarget.setRetries(2);
comtarget.setTimeout(5000);
//Create PDU for V1
PDUv1 pdu = new PDUv1();
pdu.setType(PDU.V1TRAP);
pdu.setEnterprise(new OID(trapOid));
pdu.setGenericTrap(PDUv1.ENTERPRISE_SPECIFIC);
pdu.setSpecificTrap(1);
pdu.setAgentAddress(new IpAddress("192.168.50.123"));
//Send the PDU
Snmp snmp = new Snmp(transport);
System.out.println("Sending V1 Trap to " + ipAddress + " on Port " +
port);
snmp.send(pdu, comtarget);
snmp.close();
}
catch (Exception e)
{
System.err.println("Error in Sending V1 Trap to " + ipAddress + " on
Port " + port);
System.err.println("Exception Message = " + e.getMessage());
}
}
Thanks & Regards,
keepFaith
