Re: sysORTable call from subagent

Hi,

I'm having the same problem when registring to the sysORTable from the
example demon from the subagent tutorial.
http://www.net-snmp.org/tutorial/tutorial-5/toolkit/demon/index.html

Should I use register_sysORTable() in the subagent to register to the
masters sysORTable or should I use some other function to trigger the
callback functionality?

This is what i've added to the init_nstAgentSubagentObject() function:

void
init_nstAgentSubagentObject(void)
{
    static oid      nstAgentSubagentObject_oid[] =
        { 1, 3, 6, 1, 4, 1, 8072, 2, 4, 1, 1, 2, 0 };

    /*
     * a debugging statement.  Run the agent with -DnstAgentSubagentObject
to see
     * the output of this debugging statement.
     */
    DEBUGMSGTL(("nstAgentSubagentObject",
                "Initializing the nstAgentSubagentObject module\n"));

    /*
     * the line below registers our variables defined above as
     * accessible and makes it writable.  A read only version of any
     * of these registration would merely call
     * register_read_only_int_instance() instead.  The functions
     * called below should be consistent with your MIB, however.
     *
     * If we wanted a callback when the value was retrieved or set
     * (even though the details of doing this are handled for you),
     * you could change the NULL pointer below to a valid handler
     * function.
     */
    DEBUGMSGTL(("nstAgentSubagentObject",
                "Initalizing nstAgentSubagentObject scalar integer.  Default
value = %d\n",
                nstAgentSubagentObject));

    netsnmp_register_int_instance("nstAgentSubagentObject",
                                  nstAgentSubagentObject_oid,
                                  OID_LENGTH(nstAgentSubagentObject_oid),
                                  &nstAgentSubagentObject, NULL);

    DEBUGMSGTL(("nstAgentSubagentObject",
                "Done initalizing nstAgentSubagentObject module\n"));

  /* register compliance in sysORTable */
  {
    register_sysORTable(nstAgentSubagentObject_oid,
            OID_LENGTH(nstAgentSubagentObject_oid),
            "nstAgentSubagentObject");
  }
}
