On an ethereal trace after doing what is described
below, I had to also add this code because I noticed
that snmp_pdu_build does not add the agent_addr for
v2c traps
cp = asn_build_string(cp, pkt_len,
(u_char) (ASN_IPADDRESS |
ASN_PRIMITIVE),
(u_char *) pdu->agent_addr,
4);
My ethereal trace shows:
"40 04 0a 56 f0 1d" as the last few bytes and the
address matches what I set: 10.86.240.29
How do I make the receiving end recognize this as the
agent_address?
Thanks.
