Re: Question on pass_persist feature of net-snmp
Hi Dave, Thanks a lot for your response. After reading your post, I used the snmpconf tool to configure the access control on the agent, following the tutorial on this page http://net-snmp.sourceforge.net/tutorial/tutorial-5/demon/snmpd.html#location Currently I have the following line in the snmpd.conf file to allow access for the OID * rocommunity public default .1.3.6.1.3.1.1 * However, when I execute the snmpget command, my Java program is still not being called and I get an error, although a different error to the one I got previously. *EMNETS-MIB::emnetsMIB = No Such Instance currently exists at this OID* Could you tell me if the line "*rocommunity public default .1.3.6.1.3.1.1*" is sufficient for allowing access to the OID?

One aspect of Net-SNMP that should be documented with regard to embedded systems is whether or not Net-SNMP assumes that the system it is running on has a hostname. On some embedded systems the hostname (the string returned by gethostname()) has been left empty. Additionally, on many embedded systems DNS has not been set up (empty /etc/resolv.conf). People deploying Net-SNMP on such an embedded system need to know which components of Net-SNMP rely on access to a DNS server, if there are any such components.

Regarding runtime size: many embedded systems use SDRAM memory. The smallest SDRAM modules being sold today that I know of are 64 MB in size. And I know of embedded systems with 32 MB RAM in which UCD-SNMP has been deployed successfully. Regarding static buffers: the space occupied in an executable by a static buffer that has been stored by the compiler in a BSS section is independent of the buffer size. Regarding executable size: a filesystem like cramfs, cromfs or squashfs can be a great help to reduce the amount of non-volatile storage occupied by an executable.

[SPAM] about 5.4.2.1. insert time very long
Dear all :
I have a question about CONTAINER_INSERT function , .
I use CONTAINER_INSERT to insert multi index data which is 18 X 512 volumn in net-snmp 5.1.3 . It works.
But when I upgrade to net-snmp 5.4.2.1 . CONTAINER_INSERT take more time after insert more and more entry .
Shall I change my code architecture?
Here is code
void
init_quanta_s31elLogTable(void)
{
s31elLogTable_context *context;
netsnmp_index index;
oid index_oid, sub_index_oid, temp_index_oid[2];
int time1,time2 ;
time1 = clock();
#ifdef s31elLogTable_MULTI_INDEX
DEBUGMSGTL(("mySnmp",
"Initial 's31elLogTable' table (multi-index)...\n"));
#else
DEBUGMSGTL(("mySnmp", "Initial 's31elLogTable' table...\n"));
#endif
initialize_table_s31elLogTable();
for (index_oid = 1; index_oid <= s31elLogTable_ROW_MAX; index_oid++) {
for (sub_index_oid = 1; sub_index_oid <= s31elLogTable_SUB_ROW_MAX;
sub_index_oid++) {
temp_index_oid[0] = index_oid;
temp_index_oid[1] = sub_index_oid;
index.oids = temp_index_oid;
index.len = 2;
context = SNMP_MALLOC_TYPEDEF(s31elLogTable_context);
s31elLogTable_extract_index(context, &index);
time1 = clock();
CONTAINER_INSERT(cb.container, context);
time2 = clock();
system_printf("extract_index take %d\n",time2-time1);
}
}
}

Can you expand a bit on exactly what you are trying to model here. If this is effectively an array of integer values, then SNMP would normally structure this as a table, containing an integer-based column. That may or may not be suitable for your requirements, but we'd need to know a bit more detail of what you are trying to do, before we could offer sensible suggestions.

Remember that a single SNMP request may contain several different MIB objects - possibly from different areas of the overall MIB tree. If the agent attempted to re-use a single shared buffer for implementing multiple objects, then there is a very real danger that the processing for one object could over-write the processing for another. And introducing multiple such buffers would then need some mechanism for indicating which buffers were available. Extra complexity, additional overheads, and more to go wrong.

The question is more - what object files would need to be linked. It's conceivable that an intellegent linker might be able to omit unnecessary modules, but I'm not entirely convinced.

(And dynamic loading of modules muddies the water further, since such a module might require one of the hitherto unused helpers).
