Hi everybody,
First of all thanks on your reply Dave,

Hummm i see,

Then how can it be accomplished if you want to get SNMP data from several
machines behind the SNMP Proxy?

Imagine that you have 1..N servers in a private network and you want to
extract with SNMP queries the InOctets From more than one machine.

You must get them through the SNMP proxy which is the machine you can query,

.... or am I thinking in a wrong way ?

I accomplished the scenario where I proxy to two host machines with
different OIDs.

But I want to get DATA from more machines and the OID is the same.
I was wondering if I can make a snmpbulkwalk request to the NET-SNMP server
that proxies the request to the several machines behind it but with the same
OID.

How can we accomplish a setup like this?
I wonder if I am not the only one that wants a similar setup.
I googled but I didn't find any
 
Best regards
Nuno

That much will work.
But adding:

> proxy -v 2c -c <community> <host ip5> <oid1>

won't.
If the agent receives a request for "oid1", then what
should it do?
Iit's been told to send such requests to ip3.
But it's also been told to send them to ip5.
Which should it do?   It can't do both!

Instructions to a computer should be clear and
unambiguous.  This situation is not, and the agent
can't cope with it.

Stick to one destination for a given OID (or OID subtree)
and things should work.

Dave
