Re: Sending Information through snmpget

Thanks again Dave.

I'm working with a existing MIB(and I wouldnt like to edit it), and the use
of the context(v3) or community string(v1 v2c) is not a good solution to me,
because the management aplication will not be implemented by me, I'll just
provide the agent.

Could you(or other) tell me if there's a way to extend the agent by
implementing a single module to extend the whole MIB, instead of one for
which entry in the MIB??

I want to do something like that: snmpget sends my agent a request like this
- snmpget ... MYMIB::MIBDATA.1.0.22.1 .  When it gets to the agent, it would
repass it to my extending module(MIBDATA). Inside the handler then I can get
the rest of the requisition( 1.0.22.1) and choose wich data is being
requested.  Is it possible??

Thanks and sorry about the bad english(again)
