Is the host or the agent running on a little endian machine? You may have to byte swap at the appropriate location to get network order.

For my MIB I created a C code using mib2c, I added a few lines to add a row to my table to see if everything is OK. And there is my problem, when i do snmpwalk: $snmpwalk localhost .1.3.6.1.4.1.7777 I get: SNMPv2-SMI::enterprises.7777.1.2.1.1.1.25.10.168.192 = IpAddress: 192.168.10.25 SNMPv2-SMI::enterprises.7777.1.2.1.1.2.25.10.168.192 = INTEGER: 12345 SNMPv2-SMI::enterprises.7777.1.2.1.1.3.25.10.168.192 = STRING: "test" As you can see IpAddress and OID are in different order. Maybe there is something wrong with my code from witch the row is added. Please look at my code and table definition: mgTestTable OBJECT-TYPE SYNTAX SEQUENCE OF MgTableEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "This example table is implemented in the agent/mibgroup/examples/data_set.c file." ::= { mgTestTables 1 } mgTableEntry OBJECT-TYPE SYNTAX MgTableEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "A row describing a given working group" INDEX { rowIp } ::= {mgTestTable 1 } MgTableEntry ::= SEQUENCE { rowIp IpAddress, rowInteger INTEGER, rowString OCTET STRING, rowRowStatus RowStatus } rowIp OBJECT-TYPE SYNTAX IpAddress MAX-ACCESS read-create STATUS current DESCRIPTION "" ::= { mgTableEntry 1 } rowInteger OBJECT-TYPE SYNTAX INTEGER MAX-ACCESS read-create STATUS current DESCRIPTION "" ::= { mgTableEntry 2 } rowString OBJECT-TYPE SYNTAX OCTET STRING MAX-ACCESS read-create STATUS current DESCRIPTION "" ::= { mgTableEntry 3 } rowRowStatus OBJECT-TYPE SYNTAX RowStatus MAX-ACCESS read-create STATUS current DESCRIPTION "The status of this conceptual row." ::= { mgTableEntry 4 } And my code: /* * Note: this file originally auto-generated by mib2c using * : mib2c.create-dataset.conf,v 5.4 2004/02/02 19:06:53 rstory Exp $ */ #include <net-snmp/net-snmp-config.h> #include <net-snmp/net-snmp-includes.h> #include <net-snmp/agent/net-snmp-agent-includes.h> #include "mgTestTable.h" void init_mgTestTable(void) { static oid mgTestTable_oid[] = {1,3,6,1,4,1,7777,1,2,1}; size_t mgTestTable_oid_len = OID_LENGTH(mgTestTable_oid); netsnmp_table_data_set *table_set; table_set = netsnmp_create_table_data_set("mgTestTable"); table_set->allow_creation = 1; netsnmp_table_set_add_indexes(table_set, ASN_IPADDRESS, 0); netsnmp_table_set_multi_add_default_row(table_set, COLUMN_ROWIP, ASN_IPADDRESS, 1, NULL, 0, COLUMN_ROWINTEGER, ASN_INTEGER, 1, NULL, 0, COLUMN_ROWSTRING, ASN_OCTET_STR, 1, NULL, 0, COLUMN_ROWROWSTATUS, ASN_INTEGER, 1, NULL, 0, 0); netsnmp_register_table_data_set(netsnmp_create_handler_registration("mgTestT able", NULL, mgTestTable_oid, mgTestTable_oid_len, HANDLER_CAN_RWRITE), table_set, NULL); char ip_val[4] = { 192, 168, 10, 25 }; int int_val = 12345; netsnmp_table_row *row = netsnmp_create_table_data_row(); netsnmp_table_row_add_index(row, ASN_IPADDRESS, (char *) ip_val, 4); netsnmp_set_row_column(row, COLUMN_ROWIP, ASN_IPADDRESS, (char *) ip_val, 4); netsnmp_set_row_column(row, COLUMN_ROWINTEGER, ASN_INTEGER, (char *) &int_val, sizeof(int)); netsnmp_set_row_column(row, COLUMN_ROWSTRING, ASN_OCTET_STR, "test", strlen("test")); netsnmp_table_dataset_add_row(table_set, row); } Could you help me with my problem. By the way: could you please tell me how to add a row to my table using snmpset command? ------------------------------------------------------------------------- Take Surveys. Earn Cash.
