The log levels I asked you to utilize shows all socket creation activity and all agentx protocol processing. When trying to debug agentx issues that is a lot mure helpful than the logs you showed which includes some parts of connectionless communications (yes, agentx is a connected protocol). Could you, pretty please, rerun with ther debug flags I indicated so I get a hunch about what is happening after the agent have recieved the request. /MF > > How can I know if the sub agent had registred correctly the OIDs? > > Moreover, I read that as a good advice you can generate C code and test it > > on the master agent and after that move it to the sub agent.
