[SNMP4J] if I can distinguish the response between wrong community and no snmp service

[pengli li]

Hi frank:

       I have a question about snmp4j, think about two scene.

          1. I fetch message form a host which has no SNMP service, then I
get a response TIME OUT

          2. I fetch message from a host which has SNMP service ,But I used
a wrong community, then I get a same response TIME OUT

       My question is, how to distinguish them with snmp4j?



Regards
