Me again...
To see if I reproduce the same problem with the latest version of net-snmp,
I try my sample with net-snmp v5.3.1 (instead of v.5.0.11).
The problems I'm facing now are:
- the index retrieved with register_int_index is always -1
- I get a long list of error messages 'registering pdu failed: 263!'
The sample I test is identical to the sample which was running correctly
with net-snmp v5.0.11.
Here is the code of my sample:
void init_GenServerTable()
{
oid genServerTableOid[] =
{ 1, 3, 6, 1, 4, 1, 99999, 10000, 1, 1 };
size_t genServerTableOidLen = OID_LENGTH(genServerTableOid);
u_long allocatedIndex = register_int_index(genServerTableOid,
genServerTableOidLen, ANY_INTEGER_INDEX);
oid genServerAllocatedOid[] =
{ 1, 3, 6, 1, 4, 1, 99999, 10000, 1, 1, 1, 1 };
size_t genServerAllocatedOidLen = OID_LENGTH(genServerAllocatedOid);
genServerAllocatedOid[genServerAllocatedOidLen - 1] = allocatedIndex;
netsnmp_table_data_set *genServerTable =
netsnmp_create_table_data_set("genServerTable");
netsnmp_table_dataset_add_index(genServerTable, ASN_UNSIGNED);
netsnmp_table_set_multi_add_default_row(genServerTable,
2,
ASN_OCTET_STR, 0, NULL, 0,
3,
ASN_OCTET_STR, 0, NULL, 0,
4,
ASN_OCTET_STR, 0, NULL, 0,
5,
ASN_UNSIGNED, 0, NULL, 0,
0);
netsnmp_handler_registration * handlerServerTable =
netsnmp_create_handler_registration
("genServerTable",
NULL,
genServerAllocatedOid, //genServerAllocatedOid,
genServerAllocatedOidLen - 2, //genServerAllocatedOidLen,
HANDLER_CAN_RONLY);
handlerServerTable->range_subid = genServerAllocatedOidLen - 1;
handlerServerTable->range_ubound = 5;
int res = netsnmp_register_table_data_set(handlerServerTable,
genServerTable, NULL);
if ( res != MIB_REGISTERED_OK )
{
snmp_log(LOG_ERR,"Unable to register the Server Row: res = %d.\n", res);
}
// Add a Row
netsnmp_table_row *row = netsnmp_create_table_data_row();
snmp_log(LOG_INFO,"Index found=%d.\n", allocatedIndex);
netsnmp_table_row_add_index(row, ASN_UNSIGNED, &allocatedIndex,
sizeof(allocatedIndex));
netsnmp_set_row_column(row, 2, ASN_OCTET_STR,
"Test1", strlen("Test1"));
netsnmp_set_row_column(row, 3, ASN_OCTET_STR, "Test2",
strlen("Test2"));
netsnmp_set_row_column(row, 4, ASN_OCTET_STR,
"Test3", strlen("Test3"));
u_long pid = 1500;
netsnmp_set_row_column(row, 5, ASN_UNSIGNED, (const char *)&pid,
sizeof(pid));
netsnmp_table_dataset_add_row(genServerTable, row);
}
RETSIGTYPE
stop_server(int a) {
keep_running = 0;
}
int
main (int argc, char **argv)
{
// print log errors to syslog or stderr
snmp_enable_stderrlog();
// Sub-agentX
netsnmp_ds_set_boolean(NETSNMP_DS_APPLICATION_ID,
NETSNMP_DS_AGENT_ROLE, 1);
// Read configuration file
netsnmp_ds_set_string(NETSNMP_DS_LIBRARY_ID, NETSNMP_DS_LIB_OPTIONALCONFIG,
"App1.conf");
netsnmp_ds_toggle_boolean(NETSNMP_DS_APPLICATION_ID,
NETSNMP_DS_AGENT_NO_ROOT_ACCESS);
netsnmp_ds_set_string(NETSNMP_DS_APPLICATION_ID, NETSNMP_DS_AGENT_X_SOCKET,
"/home/arnboden/snmp/master");
// Set the communication Port with the master agent
netsnmp_ds_set_string(NETSNMP_DS_APPLICATION_ID, NETSNMP_DS_AGENT_PORTS,
"1400");
SOCK_STARTUP;
// initialize the agent library
init_agent("App1");
init_mib_modules();
// Load the table
init_GenServerTable();
init_snmp("App1");
keep_running = 1;
signal(SIGTERM, stop_server);
signal(SIGINT, stop_server);
snmp_log(LOG_INFO,"App1 is up and running.\n");
sendSpecificTrap();
while(keep_running)
{
agent_check_and_process(1);
}
snmp_shutdown("App1");
SOCK_CLEANUP;
return 0;
}
Any suggestions?
Thanks in advance.
