[SNMP4J] About SNMP4J

[Mauricio Reyes]

Hello,

I modifyed the code to this:
if (version == SnmpConstants.version3)
{
      byte[] tt={01,02,03,04,05,06};
      System.out.println("engineID: "+new 
OctetString(/*MPv3.createLocalEngineID()*/tt));
      USM usm = new USM(SecurityProtocols.getInstance(),new 
OctetString(/*MPv3.createLocalEngineID()*/tt), 0);
      SecurityModels.getInstance().addSecurityModel(usm);
      addUsmUser(snmp);
}

It prints out engineID: 01:02:03:04:05:06

And on the snmptrapd.conf I have this:

createUser -e 010203040506 mtest MD5 mmprueba DES mmprueba

Bu I still receive the same error on the snmptrapd demon.

Any idea what can be the problem?

Thanks for your help. Sorry to bother you so much.

Mauricio.
