Oops.
I've just spotted that you're talking about SNMP
*trap* packets, rather than more general requests.
In this particular case, there _is_ a field for this
value in the PDU structure - 'agent_addr'.
The following code from 'apps/snmptrap.c' shows how
it's set up in that tool:
// line 259
pdu_in_addr_t = (in_addr_t *) pdu->agent_addr;
// lines 290-295
agent = argv[arg];
if (agent != NULL && strlen(agent) != 0) {
*pdu_in_addr_t = parse_address(agent);
} else {
*pdu_in_addr_t = get_myaddr();
}
Note that this *only* works with IPv4 requests.
If you're using anything else (IPv6, or non-IP
transports), then this field should be left empty.
Sorry for the confusion.
