FW: How can I bypass USM+VACM?

 
Hey,
 
I got a master agent running on my system.
I got also an SNMP client running on the same system (different
process),
and I'd like the client to be able to query the master agent without USM
authentication or VACM authorization limitations.
The reason is, that the client performance should be independent of the
USM and VACM tables which may be changed.
 
What would be the easiest way to hack this?
 
I guess I just need to find the function that calls the USM
authentication and the VACM authorization, and make it return possitive
permission when the PDU's IP is a local one (127.0.0.1).
Which are these functions?
 
P.S:
I recall that net-snmp 5.3 has some kind of local security module,
what's that all aobut?
 
Thanks,
Erez.

 
(BTW: I tried sending this to the coders mailling list, but it did not
arrive)
