[SNMP4J] SNMPv3 discovery process questions

[Tony Willett]

Hello all,

I am still trying to figure out an issue I am having with engine boot time
synchronization.

I have written an agent application that has an agent object that is loosely
based on org.snmp4j.agent.BaseAgent. I also have a manager application that
very closely resembles the example code in the javadocs for org.snmp4j.Snmp.
I had previously been able to get v3 working between the agent and manager
for get and set requests. However, if I start the manager more than 150
seconds after the agent then the agents complains about the engine boot time
window and responds to the manager with the 1.3.6.1.6.3.15.1.1.2.0 response.
Frank pointed out that I was probably using the same engine id for manager
and agent. This was indeed true. I changed the manager engine id to be
unique. 

I am currently adding a UsmUser to the agent associated with the agent's
engine id (authoritative engine id). Likewise I am adding a UsmUser with the
discovered authoritative engine id. The problem still exists that I can
connect and get responses to the manager set/get requests, but if I try
running the manager more than 150 seconds after the agent I get the
1.3.6.1.6.3.15.1.1.2.0 response. 

It appears to me that the auto discovery is not requesting the authoritative
engine boot time, so it starts at 0 and is out of window. Am I wrong in
assuming that the auto discovery is supposed to sync the time in the
manager?

Thanks for any help,
