Hi Jeff, You need a MIB compiler or at least a name to OID mapping to do this at runtime. The latter can be generated at compile time with AgenPro or MIB Explorer (http://www.agentpp.com). To use MIB information, you can use JASMI (see http://www.mibdesigner.com) or any other Java MIB compiler.

Re: [SNMP4J] DefaultMOTable into DefaultMOtable.

Jean, SMI (SNMP) does not support table-within-a-table. You need to model your MIB in a relation database table fashion. Tables in SMI can have relations which are based on the index definitions of the tables. See the tables.pdf paper from David Perkins (snmpinfo.com if I remember it correctly)

Re: [SNMP4J] Sending Traps using snmp4j-agent library

Hi Pidarp, The TestAgent is capable of sending out traps (it actually does with its default config). If you cannot see the trap with your sniffer then (a) you are sniffing on the wrong interface (b) your OS does not support sniffing on the interface the agent uses (c) your agent configuration has

Re: [SNMP4J] SNMP GET, SET, INFORM problem

Aidan, If you do not specify a contextengineID, SNMP4J will set it to the authoritative engine ID. The usmNotInTimeWindow error can have many causes. First, I would check if your engine ID differs from that of the agent. Best regards, Frank Aidan Diffey wrote: All. I am writting an SNMP

Re: [SNMP4J] Multiple UDP transport mappings

Hi Ellis, When using several UDP (or TCP) transport mappings you should make sure, that you use only the Snmp methods that take the transport mapping as parameter. Then you can choose the mapping you want to use. The default NotificationOriginator however, will not distinguish between those

Re: [SNMP4J] Thread poll organizer question.

Hi Lukasz, First of all, I assume that you meant pool when you wrote poll, right? SNMP4J does not use ThreadPool except in the MulitThreadedMessageDispatcher. If you use it, the a thread is taken from the pool to run the onResponse(..) callback. That's all. Best regards, Frank Łukasz
