Do you have any examples on using this for snmpv3? A simple snmpv3 get perhaps?
I thought it would be similar to using snmpv2c but I'm getting an Unsupported security model Exception.

Is there any support for SNMP v1 Get Requests in the SNMP4J Provider?

Hi

I have created an SNMP listener and it works for most of the received traps. However when the listener receives traps from a "table" something odd occurs.

The extractIndexes method in MibbleIndexExtractor.java causes an exception.

The oid String and instanceOid String are for some reason identical so it causes an out of bound exception when it tries to create the suboid and does not print out the trap.

I am listening to traps from an Ericsson object and all the other traps that are not inside a table works fine. I am using the ERICSSON-ALARM-MIB and all the required imports for that MIB. The overview of this MIB can be seen at https://mibs.observium.org/mib/ERICSSON-ALARM-MIB/

Any suggestions on how to fix this issue?

I have also asked the question on https://stackoverflow.com/questions/55240710/snmp-listener-can-not-read-trap-from-oids-that-are-entries-in-a-table

Best regards
Michael

It looks like this was originally under Apache License. I'd use this project if it would be available under Apache License. Could you make it dual licensed?

Carl,

I spoke with Per Cederberg the creator of Mibble and asked if they would consider putting Mibble on Maven. Per set up a Maven repo for Mibble on mibble.org which I believe should have a newer version of the library than tnm4j currently. I also did a fork of tnm4j and experimented with updating both Mibble and SNMP4J. Most everything looked to update without issue.

Would you consider updating dependencies? I can submit a PR from my fork if you like but you might wanna double check and test anything I submit.

Hi,

It looks like support for SNMP SET operations is not implemented, but the README mentions

In addition to the get method, the context provides methods to support all of the fundamental SNMP operations: GET, GETNEXT, GETBULK, and SET.

Am I missing something? Thanks!

See https://mvnrepository.com/artifact/org.soulwing.snmp/tnm4j/1.1.1

After much debugging, I have found that SNMP4j has deprecated AuthSHA and AuthMD5. If you still need these, then you can re-enable them with this one-liner:

SecurityProtocols.getInstance().addAuthenticationProtocol(new AuthSHA());

This is not a tnm4j bug, but I wanted to put this here for others struggling with the same problem.

Hello,
I am trying to authenticate against device using SNMPv3 with auth but no encryption (authNoPriv mode).

However, if I create a SimpleSNMPv3Target with setPrivType set to null, I got a NullPointerException.

I went through the source code and I have come to a conclusion, that it cannot be done. If I look at this line

However, if I do that, the code fails because of this line

As a consequence, the desired security level is never reached.

Additional notes: NullPointerException is obviously fired by the switch-case statement in privType function here

When calling SNMPContext#close() the function will never exit.
I am using Java 8 and JavaFX.

When performing an asyncwalk and the host does not respond and the response.get() throws a timeoutexception, the host is retried indefinitely even if the TimeoutException is handled.

I got this error when I try to build project with Maven:

Failed to execute goal on project Test: Could not resolve dependencies for project com.Test:jar:0.2: Failed to collect dependencies at org.soulwing.snmp:tnm4j:jar:1.0.9 -> org.snmp4j:snmp4j:jar:2.3.3: Failed to read artifact descriptor for org.snmp4j:snmp4j:jar:2.3.3: Could not transfer artifact org.snmp4j:snmp4j:pom:2.3.3 from/to oosnmp (https://oosnmp.net/dist/release): Transfer failed for https://oosnmp.net/dist/release/org/snmp4j/snmp4j/2.3.3/snmp4j-2.3.3.pom: Certificate for <oosnmp.net> doesn't match any of the subject alternative names: [morewap.com, www.morewap.com].

Can you help with this?

We're back leveled on some dependencies.

Latest snmp4j series 2.5.x made some changes in the (horribly broken) mechanism they were using in 2.3.3 to deal with socket timeout. Those changes break our workaround for their crummy timeout mechanism. Need to investigate.

I opened an issue to get Mibble artifacts into Maven Central, but it's been stalled.

Hello,
is it possible to add SHA-256 AuthType for SnmpV3 ?
I tried to override SnmpV3Target class in my project but this lead to copy-paste 30% of the lib because a lot of classes in lib are not public.
It seems that small changes in lib are a better solution. Maybe someone else will also need SHA-256 AuthType support.
Am I correct, that changes are needed only in these 2 places?

org.soulwing.snmp.SnmpV3Target.AuthType
org.soulwing.snmp.provider.snmp4j.UserTargetStrategy#authType

I am unable to build.

Any ideas?

Hai, I just want to know whether this project is still under development.

I am using this library in my Apache NiFi project, to perform a walk operation but it shows the following error
java.lang.NoSuchMethodError: 'void net.percederberg.mibble.asn1.Asn1Parser.reset(java.io.Reader, net.percederberg.grammatica.parser.Analyzer)' at net.percederberg.mibble.MibLoader$MibSource.parseMib(MibLoader.java:970) at net.percederberg.mibble.MibLoader.loadQueue(MibLoader.java:724) at net.percederberg.mibble.MibLoader.load(MibLoader.java:550) at net.percederberg.mibble.MibLoader.load(MibLoader.java:451) at org.soulwing.snmp.provider.mibble.CachingMibRepository.load(CachingMibRepository.java:79) at org.soulwing.snmp.provider.mibble.MibbleMib.load(MibbleMib.java:226)
can you help me to resolves it.
Thanks in Advance.

Hello, Carl Harris
I did not found any other way to reach you, so I will ask my question here.
Is there is any possibility of licensing this lib for commercial use?
GNU GPL does not fit with my company's third-Party software usage policy.

Hello,

Can I use this Code base as dependency in my Organization project. My requirement is to load custom MIB File and Add the MIB to SNMPAgent from snmp4j. @ceharris Please let me know if i can do this action. Do i need any license to use this repo.

Thanks

When resolving a numeric OID to a name, a search of loaded MIBs is performed, in the reverse order in which MIBs have been loaded. This works, but requires the load order to be carefully considered by the tnm4j user.

A nice improvement would be to search all loaded MIBs and return the object name that matches with the smallest suffix of remaining unresolved OID string. If all needed MIBs are loaded, the unresolved part will always be the instance sub-identifier (assuming the OID is an object instance identifier).

For example, if SNMPv2-MIB is loaded and RFC1155-SMI is loaded, in the current implementation an OID-to-name lookup for 1.3.6.1.6.3.1.1.4.1.0 could return two possible values, depending on the order in which the Mib instance is loaded:

1. snmpTrapOID.0
2. internet.6.3.1.1.4.1.0

In this case result 1 is better, because the suffix remaining after the name is shorter than in result 2; it is a better match, and less likely to surprise tnm4j users.
