Hi Ron, What you observe is correct and matches the SNMP standard requirements. In SNMP, the trap receiver is authoritative. That is, the sender must use the SNMP(v3) user name and password the receiver knows and accepts. Hope this helps anyway ;-) Best regards, Frank > On 2 Feb 2017, at 22:0

Re: [SNMP4J] Set USM security parameters per request

Hi Ron, You can remove the time information for a specific target by calling UsmTimeTable.remove(engineID). You can get the engineID by calling MPv3.getEngineID(Address). Best regards, Frank > On 2 Feb 2017, at 00:01, Ronald Braswell wrote: > > I have code which calls USM.removeEngineTime(eng

Hi Philippe, Cross posting messages is not good style and does not help. If a question is not answered, it might be helpful to rephrase it and add more details to enable readers to understand it. BTW, I already answered your posting an Dec 29th, 2016. Best regards, Frank > On 27 Jan 2017, at

Re: [SNMP4J] Snmp4j-Agent SNMP-MPD-MIB missing for reading snmpInvalidMsgs ?

Hi Ullrich This seems to be an error (that the SNMP-MPD-MIB counters are not implemented by the AgentConfigManager. I ill add the missing code for the next release. Meanwhile you can, of course, implement your own CounterListener for those three counters in your own MIB. Best regards, Frank

Re: [SNMP4J] Force snmp to use a private key

Hi, You can use the following constructor of UsmUserEntry, if you only have the keys: http://www.snmp4j.org/doc/org/snmp4j/security/UsmUserEntry.html#UsmUserEntry(byte[],%20org.snmp4j.smi.OctetString,%20org.snmp4j.smi.OID,%20byte[],%20org.snmp4j.smi.OID,%20byte[]) If you know the passphrase an

Re: [SNMP4J] Single snmpset setting a RowStatus first to createAndWait and then to active not working on snmp4j-2.x

Hi Iker, There was a bug/non-optimal code in SNMP4J-Agent 1.x which has now been fixed/improved. SNMP4J-Agent 2.x enforces now standard conformity which means you have to use RowStatus createAndGo to set a new row active with a single SET PDU. Hope this helps anyway. Best regards Frank > Am

Re: [SNMP4J] FW: suddent error coming out of nowhere

Hi Philippe, It is a simple NullPointerException and you have the stacktrace and the code. It should be easy to identify. From the stacktrace, it seems that you are using an old version of SNMP4J. It would be always helpful to note that (and the exact version number) in your request for help.

Re: [SNMP4J] thread safety on SNMP

Hi Mert, Yes, Snmp is thread safe as it could be. I will take care about the Closable interface at least for the 3.0 release (based on Java 9 for DTLS support). Best regards, Frank > On 8 Dec 2016, at 11:55, Mert Çalışkan wrote: > > Hi, > > I’m in the process of integrating SNMP4J into Pa

Re: [SNMP4J] snmp4j-smi-pro issue

Hi Ronald, Most likely, you get the IMPORTS from a different MIB module, or the MIB module could not be parsed correctly (this could happen if you use the lenient mode with a broken MIB module). Hope this helps. Best regards, Frank Am 03.11.2016 um 17:27 schrieb Ronald Braswell: I am trying

Hi Steffen, I cannot imagine a standard conforming agent that will cause the situation you described, but anyway you are right, that there is a "hole" in the algorithm of TableUtils. To fix it, you can replace the "relevant part in TableRequest.onResponse" with boolean sentChunk; if (!(sen

Re: [SNMP4J] Using localized keys

Hi Ron, There are two cases you have to differentiate: 1. You have already localized passphrases for your target: Then use USM.addLocalizedUser(...) 2. You have plain text passphrases for your target: Then use USM.addUser with a UsmUser that had been created with a localizationEngineID.
