When snmptrapd receives a snmptrap it is _not_ supposed to use the IP-source address of the packet as the sender of the trap, but look inside the snmp-packet (agent-addr in SNMPv1) to see who the trap really comes from.

There are several RFCs and papers about this (and we have mentioned it earlier).

Please?

All snmptrapd does is collect the values from a trap and store that as an object that traphandlers may use. That object contains both source and agent, where source is the ip-source address and agent is the agent-address. However, if you are referring to the linkupdown-traphandler, I agree that the use of trap source to locate the device that triggered the event is wrong. This will be fixed in an upcoming patch. -- John-Magne Bredal NTNUninett
