Sending real data [was Re: [SNMP4J] Newbie Agent help please]

Thanks, Gene.

I created my own version of TestAgent, and used AgenGen to create the Java 
stubs for our MIB.  My agent will now respond to SNMP requests, which is 
great.

I'm stuck at the next stage, however.  I need for the agent to behave like 
a particular printer, and respond accordingly.  So, for example, when I 
send .1.3.6.1.4.1.641.2.1.2.1.2.1 it currently returns prtgenFamilyId.0 - 
however, I need it to respond with a String containing the model name of 
the specific printer I'm simulating.

How did I accomplish this?  Is there an interface I can implement to do 
this?

Also, what is an ifTable?!

cheers,

David

I started off using the TestAgent and IfMIB code in snmp4j-agent.test.
This will give you a fully functional agent and ifTable. That worked
extremely well for me, although I did have issues related to v2c that I
don't fully understand.
