Hi Dave,

 

I was using library without SSL support so it was giving the error below

> > Encryption support not enabled.

> > snmpset: USM encryption error

 

But when I replaced this library with the one that supports SSL, following 
error came:

> snmpwalk: Authentication failure (incorrect password, community or key)

 

I tried a simple query as u suggested. Please checkout if the query is correct. 
And why it is giving "snmpset: Unknown Report message" error.

That's not the error you were reporting yesterday.

Then you said that it was complaining about

 

> > Encryption support not enabled.

> > snmpset: USM encryption error

 

Now it seems that the request is being sent successfully.

 

 

 

I don't know how the remote box is configured, but the error message

     Authentication failure (incorrect password, community or key)

would tend to indicate that it doesn't like one (or more) of the SNMPv3

username, authentication/encryption protocol or key, or the context

string that you are using.

 

I'd suggest that you try with a simpler query, perhaps a noAuth

or authNoPriv request using the default context - and work up to

the full settings that you need to use.

 

But look closely at how the access control is configured on the remote agent.

 

Dave
