[AGENT++] few questions about UTargets and SNMPv3 trap sending

[Jochen Katz]

Hi,

UTarget can also be used for v1/v2c.

> 2.	When trying to use UTarget and setting security name and specifying

If you get success, the trap has been sent. You can verify this through
a packet sniffer.

It is the OK return code of v3MP (see snmperrs.h)

> But trap still isn't received by manager.

The manager drops the trap for a unknown reason. Can you get some Log
info from the manager.

>    v3mp->add_to_engine_id_table(this->engineID,"127.0.0.1",162);

This line is wrong: you tell the v3MP that the manager on port 162 has
the same engine id as the agent --> This will not work! If you don't
turn engine id discovery off, you don't have to add any engine ids to
the v3MP table.
