Re: Description of issues fixed in SNMP4J?

Hi Kristoffer,

The JIRA system is not public. It is accessible for
all users which have a valid support contract.

The issue description was:
The Windows Vista JDK (versions unknown) throws a SocketClosed exception 
on a "Time-to-live exceeded" error although the socket can still be used.
Attached is a patch by XXXXXX which has been reported to solve this issue.

The solution description was:
Socket exceptions thrown in ListenThread no longer stops the thread if 
forwarding runtime exceptions is disabled in SNMP4JSettings.

Best regards,
Frank

Re: thread lock in org.snmp4j.mp.MPv3.prepareResponseMessage

Hi Shangtang,

No, I do not understand it. The stack traces do not indicate
an dead lock. Thus, some code in a notification handling
routine has not returned in a timely fassion.
But this code is not part of SNMP4J. So you will
have to debug that yourself.

Best regards,
Frank

Re: usmStatsNotInTimeWindows and then usmStatsWrongDigests

Hi Adi,

The problem seems to be that the manager (SNMP4J) resets
its MPv3 cache, because enigne boots and engine time are
reset (0 and 7 instead 1 and 2861+7+x).

At time x after the first successful request was sent, someone
deleted the Snmp instance and/or the contained MPv3
object or used a second Snmp instance with a new MPv3
instance which did not had any cache entry for the specific
SNMPv3 target engine ID.

Best regards,
Frank

Re: Please remove me from this list

Hi Fridtjof,

You can remove yourself through the same way you
subscribed at:
http://lists.agentpp.org/mailman/listinfo/snmp4j

Sending unsubscribe requests to the mailing list
is not polite, because several hundred people need
to read it.

Best regards,
Frank

Issues with SET on a read-write column

Resending the mail.

Subject: RE: [SNMP4J] Issues with SET on a read-write column

Hi Frank,

Thank you for a quick response. 
Here are my index definitions for the table mentioned earlier.

oidTestConfigEntry = new OID(new int[]{1, 3, 6, 1, 4, 1, 2197, 10, 1, 3, 12, 1});

OID oidIDXTestConfigHost = new OID(new int[]{1, 3, 6, 1, 4, 1, 2197, 10, 1, 3, 12, 1, 1});
OID oidIDXTestConfigParamName = new OID(new int[]{1, 3, 6, 1, 4, 1, 2197, 10, 1, 3, 12, 1, 2});

MOTableSubIndex[] testConfigEntryIndexes = new MOTableSubIndex[]{
    	moFactory.createSubIndex(oidIDXDispatcherRuntimeConfigHost, SMIConstants.SYNTAX_OCTET_STRING),
    	moFactory.createSubIndex(oidIDXDispatcherRuntimeConfigParamName, SMIConstants.SYNTAX_OCTET_STRING)
    };

MOTableIndex testConfigEntryIndex = moFactory.createIndex(testConfigEntryIndexes, false);

MOColumn[] testConfigEntryColumns =  new MOColumn[3];
testConfigEntryColumns[0]=
	    	 moFactory.createColumn(1,
	    				SMIConstants.SYNTAX_OCTET_STRING,
	    				moFactory.createAccess(MOAccessImpl.ACCESSIBLE_FOR_READ_ONLY)); // testConfigHost

snmp4j v3 configuration

hi ,

 Regarding this I guess this is my 3rd mail.

      I am an SNMP application developer. I am using your snmp4j-2.0.2.
I am trying snmpv3 get request.If am setting all the security related
parameters
I am getting the correct values. But if am giving anything wrong
(authUsername,passwd ,protocol etc) It's not returning the error. Some time
i
am getting some garbage values and some time I am getting error response as
null.

I am using Webnms SNMP agent simulator.

Earlier everything was perfectly fine with Netsnmp5.6.1 Manager  and same
agent

I am eagerly waiting for ur reply . Because then only I can proceed whether
to use snmp4j or not.

Expecting some reply

Regards,
Nadeesh TV

Re: SnmpV3 Encryption Provider as Configurable parameter

Hi Frank,

To elaborate on this (because the context wasn't really explained in the 
original mail of Jones):

We found that in performance tests on our product (with a big number of 
agents) that there was a high thread contention for SNMPv3 managed 
agents.   A jstack showed that a lot of our threads were running in the 
following stack frame at the moment of the jstack, which indicates that 
this functionality generates a relatively big load:

"JM-282" prio=3 tid=0x000000013f032800 nid=0x391 runnable

SampleAgent/AgentConfigManager with persistent data ?

Greetings,

I tried to run the SampleAgent by both indicating "-c
persistentConfig" file and runtime  and hardcoded a value for
configFile in SampleAgent.java, but whatever configuration I applied
to the agent during its life were not stored and I didn't see that
persistent file created after hitting Ctrl-C to terminate the agent.
Can someone help to tell what I am missing?

Thanks,
Binh.

Re: SampleAgent/AgentConfigManager with persistent data ?

Found that I missed the shutdown hook :).
