SnmpV3 about tnm4j HOT 13 CLOSED

I thought I had an example around for it, but I don't see it. I'll try to address that soon.

Here's something that should be pretty close. I don't have an SNMPv3 capable agent handy at the moment to try it myself.

  public static void main(String[] args) throws Exception {
    SimpleSnmpV3Target target = new SimpleSnmpV3Target();
    target.setAddress(System.getProperty("tnm4j.agent.address", "10.0.0.1"));
    target.setSecurityName(System.getProperty("tnm4j.agent.username", "manager"));
    target.setAuthType(SnmpV3Target.AuthType.SHA);
    target.setPrivType(SnmpV3Target.PrivType.AES128);
    target.setAuthPassphrase(System.getProperty("tnm4j.agent.auth.password", "authpasswd"));
    target.setPrivPassphrase(System.getProperty("tnm4j.agent.priv.password", "privpasswd"));
    SnmpContext context = SnmpFactory.getInstance().newContext(target);
    try {
      VarbindCollection result = context.get("1.3.6.1.2.1.1.3.0").get();
      System.out.println(result.get(0));
    }
    finally {
      context.close();
    }

  }

I have tried to use your rough draft and different iterations. I keep getting this;

Does it give you any ideas?

from tnm4j.

I seemed to of gotten around the issue by modifying provider.snmp4j.UserTargetStrategy.
To get an idea of what I think the issue is, changes can be seen here:

Looks reasonable. Make sure your changes use the same style (indents, etc) as the source you're changing, and submit a pull request. I'll merge it.

Looks like the transport model configuration was discarded when UserTargetStrategy was created and separated from another class, a long time back.

Will maven central be updated with this patch?

from tnm4j.

Yes, but I need to update dependencies in the pom before I cut a new release, and didn't have time for that this morning.

from tnm4j.

I'll update this issue when I do...

from tnm4j.

Perfect! Thanks for your help.

Could you deploy a .7 and then update dependencies in a .8 patch?

from tnm4j.

Sorry for the delay in getting back to this. Had a death in our family. It wasn't unexpected, but more sudden than expected.

So I did a 1.0.7 release today. Should hit Maven Central in the next few hours.

from tnm4j.

I'm going to open a separate issue for updating dependencies.

from tnm4j.

My condolences.

I ended up deploying a fork. There's another patch I made that seems possibly toxic but it solved an issue I was having. I'll make a separate issue for that this week hopefully with a pull request.
