RE: Fails:: SNMPGetNext and GetBulk has the IP Address Index reversed in the request.

Hi,

After a bit of investigaton, the Getnext and bulkget calls go to the next table, by adding a dummy colum entry with the below function call.

/*****************************************************************************************************************/
            case COLUMN_TABLENOOP:
                {
                    u_char x = '1';

                    netsnmp_table_build_result(reginfo, requests,
                        table_info, SNMP_NOSUCHOBJECT,
                        (u_char*) &x,
                        sizeof(x)); 
                    break;
                }
/*****************************************************************************************************************/


However the Snmpwalk does not retrive the next table column values, the call reaches the column handler with the call as below, but the snmpwalk stops here, and does not go further.


/*****************************************************************************************************************/
                snmp_set_var_typed_value( request->requestvb, ASN_OCTET_STR,
                    (u_char*)table_entry->rName,
                    table_entry->Name_len);
/*****************************************************************************************************************/


Any ideas further??

Hi Dave,

I made the host to network order suggestion, and now it works for Get, GetNext and BulkGet calls.

However iam facing a issues with Getnext/Bulk/Snmpwalk get calls going to the next table, the bulk/walk requests are NOT going to next table, it traverses to the beginning of the same table row.

Attached is the file. I really appreciate any help in this regard as this is a blocking issue.

Thanks,
Anup

If you want a quick-n-dirty hack to get things working,
you could always tweak the vplexDirectorFETable_entry
(and similar) structure to include *two* fields for the
IP address - one held in host order and one in network
order.
   Then use one for the index processing (in the get_first
and get_next routines), and the other in the handler
itself (for the column object).
