agentxPingInterval Handler and init_agentx_config() function

[Kurapati M-G19456]

Title: Message

Hi,

 

Following code is the snippet of our SNMP SubAgent.  I am facing two problems with this finction.

 

1.  init_agentx_config() is deifined in agentx_config.c and the declaration is available in agentx_config.h file.  agentx_config.h is not getting copied into the installed area when NET-SNMP is installed.  So the include path needs to be mentioned in the make of the subagent.  Is there any reason, for not copying this file into intall (/usr/include) area?  Is there any other alternative for this?

 

2.  init_agentx_config() registers the handlers for agentxSocket, agentxTimeout and agentxRetryCount, but not for the agentxPingInterval.  So, I registered the tag and handler for the agentxPingInterval in the following function.  But this ping interval is getting overwritten to default value of 15 seconds.  I observed this only with the NET-SNMP-5.1.1 realease only.  Is there any alternative for this? 

 

3.  Is the order of the calls that I am making in the init routine are correct?  Am I making necessary and sufficient calls to initialize the subagent?

 

init_subagent()

{

    /* make us a agentx client. */
   netsnmp_ds_set_boolean(NETSNMP_DS_APPLICATION_ID,
                            NETSNMP_DS_AGENT_ROLE, 1);

 

    /* set the type of the application */
    netsnmp_ds_set_string(NETSNMP_DS_LIBRARY_ID,
                         NETSNMP_DS_LIB_APPTYPE,
                         "SnmpSubagt");

 

    /* initiliaze the function pointers to parse the agentx
     * configuration paramters
     */
    init_agentx_config();
   
    /* initialize the agentxPingInterval handler */
    snmpd_register_config_handler("agentxPingInterval",
                                   snmpsubagt_netsnmp_agentx_pingInterval,

                                   NULL, "Agentx Ping Interval (seconds)");

 

    init_snmp("SnmpSubagt");
   
    m_SNMPSUBAGT_HEADLINE_LOG(INIT_SNMP_DONE);

 

    /* initialize the agent library */
    /* This function initializes the session with the Agent */
    init_agent("SnmpSubagt");

}

 

static void
snmpsubagt_netsnmp_agentx_pingInterval(const char *token, char *cptr)
{  
    int x = atoi(cptr);
           
    /* log the function entry */  
     m_SNMPSUBAGT_FUNC_ENTRY_LOG(SNMPSUBAGT_FUNC_ENTRY_PING_INT_CONF);
   
    DEBUGMSGTL(("agentx/config/PingInterval", "%s\n", cptr));
                netsnmp_ds_set_int(NETSNMP_DS_APPLICATION_ID,
                NETSNMP_DS_AGENT_AGENTX_PING_INTERVAL, x);
    return;           
}  

Please help me.

 

Thanks
