[SNMP4J] TestAgent and SNMPv3

[Ricardo Nabinger Sanchez]

Hello,

I'm trying to run the TestAgent with SNMPv3, but am not succeeding at it.

The users were not changed, but here they are:

  protected void addUsmUser(USM usm) {
    UsmUser user = new UsmUser(new OctetString("SHADES"),
                               AuthSHA.ID,
                               new OctetString("SHADESAuthPassword"),
                               PrivDES.ID,
                               new OctetString("SHADESPrivPassword"));
    usm.addUser(user.getSecurityName(), usm.getLocalEngineID(), user);
    System.err.println(user);
    user = new UsmUser(new OctetString("TEST"),
                               AuthSHA.ID,
                               new OctetString("maplesyrup"),
                               PrivDES.ID,
                               new OctetString("maplesyrup"));
    usm.addUser(user.getSecurityName(), usm.getLocalEngineID(), user);
    System.err.println(user);
    user = new UsmUser(new OctetString("SHA"),
                               AuthSHA.ID,
                               new OctetString("SHAAuthPassword"),
                               null,
                               null);
    usm.addUser(user.getSecurityName(), usm.getLocalEngineID(), user);
    System.err.println(user);
  }


I've added the subtrees I want to access, just in case this was needed:

  protected void addViews(VacmMIB vacm) {
    ...
    vacm.addViewTreeFamily(new OctetString("testReadView"),
                           new OID("1.3.6.1.2.1.4"),
                           new OctetString(), VacmMIB.vacmViewExcluded,
                           StorageType.nonVolatile);
    vacm.addViewTreeFamily(new OctetString("testReadView"),
                           new OID("1.3.6.1.2.1.4.24"),
                           new OctetString(), VacmMIB.vacmViewExcluded,
                           StorageType.nonVolatile);
    ...
  }


But when I try to query the agent, all I get is:
% java -jar SNMP4J.jar -a SHA -A maplesyrup -u TEST -p GETNEXT -Ow 127.0.0.1/12345 .1.3.6.1.2.1.4.24

And in the agent's log:

May this be related to an issue with timeouts, discussed here:
    http://lists.agentpp.org/pipermail/snmp4j/2004-December/000231.html


If I go with SNMPv2 or SNMPv1, everything is perfect:
% java -jar SNMP4J.jar -v 2c -c public -p GETNEXT -Ow 127.0.0.1/12345 .1.3.6.1.2.1.4.24

I'm sure I'm missing something pretty obvious here, but reading the docs and googling are not helping anymore.

Thanks in advance.
Regards.
