[SNMP4J]About NotificatorOriginatorImpl and field agent-addr from Trapv1

[Frank Fock]

Hi Nídia,

you can fix this by changing NotificationOriginatorImpl's
sendNotification method at:

...
         else {
           trap.setGenericTrap(genericID);
           trap.setEnterprise(new OID(new int[] { 0,0 }));
         }
//----> begin change
         TransportMapping tm =
             session.getMessageDispatcher().getTransport(address);
         if ((tm != null) && (tm.getListenAddress() instanceof IpAddress)) {
           InetAddress localAddress =
               ((IpAddress)tm.getListenAddress()).getInetAddress();
           trap.setAgentAddress(new IpAddress(localAddress));
         }
//----< end change
         break;
       }
       case MessageProcessingModel.MPv2c: {
         t = new CommunityTarget(address, community);
         pdu = new PDU();
         break;
       }
...

However, this fix will not work when you setup your transport
mapping with 0.0.0.0 as local address. If you get a V1 trap
with 0.0.0.0 agent-addr field, then you should use the IP
address of the packet anyway.

Best regards,
Frank
