Verification of VACM parameter in case of SNMPv2 request
Hi All , I have one question regarding the checking of SNMPV3 related parameters. Is it not mandatory that only in case of SNMPv3 request the VACM related parameters will be verified . For example in case of getbulk (SNMPv3) request agent has to verify if the next OID is in the correct view. But my question is in case of SNMPv2 getbulk request do agent may verify if the next OID is in correct view ? Assuming there are some default view available with agent .

Now in response PDU error index will be set to 2. No. With SNMPv2, the error index (and error status) will be set to 0. The request has succeeded, and will report the two real values together with the two noSuchInstance pseudo-values. So how manager will come to know that v2 and v3 has error in response? Because it's not an error - the agent returns values (or exception values) for all four varbinds. This is one of the most significant improvements on SNMPv1, which would have had to report a 'noSuchName' error for the second variable. The manager would not know that there was a problem with V3 as well, without trying another request (V1, V3, V4).

RE: Question regarding SNMP GET response PDU
Hi Dave, Many thanks for the response. I would like to verify my understanding. So noSuchInstance is a ASN1 type .So while encoding the PDU it will be different than other type such as INTEGER, GAUGE32 etc. So manger while decoding will come to knows that it is noSuchInstance. Please let me know if my understanding is correct? I would like to know more about how the coding is being done. Could you please suggest me which RFC I can follow? Or how it is done in NetSnmp . Regards, Somenath suppose noSuchInstance pseudo-values is 10 No. It doesn't work that way, The exception pseudo-value *is* noSuchInstance This is essentially a type in its own right - distinct from integer, octet string, OID, etc Then how manager will differentiate whether it is exception or value ? The response varbind list will look something like: v1 = integer 17 v2 = noSuchInstance v3 = noSuchInstance v4 = string hello - SF.Net email is sponsored by: The Future of Linux Business White Paper from Novell.

RE: Question regarding SNMP GET response PDU
Hi Dave, Many thanks for your response and suggestion. I would like to inform that I am trying to learn SNMP form William Stallings SNMP,SNMPV2,Snmpv3,and RMON 1 and 2. In this book it is mentioned that noSuchInstance will be put in the value field .But it was not clear for me that it is a different type it self. I would earnestly request you to suggest how SNMP can be learned in better manner. Regards, Somenath I would like to verify my understanding. So noSuchInstance is a ASN1 type. Sort of. See RFC 1905, section 3 for the definition of the VarBind structure. I would like to know more about how the coding is being done. Could you please suggest me which RFC I can follow? RFC 1905 is the document that describes SNMPv2 (though the lowest level of encoding a request into the packet that's actually sent over the network follows the Basic Encoding Rules, which is an ISO standard). Or how it is done in NetSnmp . See snmplib - especially snmp_api.c and asn1.c But I would suggest that this probably isn't the best way to learn about SNMP. You would be much better off buying a good book and studying that. Dave - SF.Net email is sponsored by: The Future of Linux Business White Paper from Novell.

RE: Multiple row creation
Hi Dev, Many thanks for your answer. Suppose I want to create two rows for two different tables in a single SNMPSET request. But the handler (CREAT AND GO) for two different rows will be different.

Yes - assuming this is a single SNMP SET request. That's exactly right. If the SET request fails, then neither row should be created. Of course, if the two rows are created using two separate SET requests, then it's perfectly valid for one creation to succeed, and the other to fail. But if you're putting both creation assignments into the same SET request, then they must stand or fall together. Dave - Take Surveys. Earn Cash.

RE: Multiple row creation
Hi Dev , Many thanks for your response. I am using mib2c.iterate.conf . I have one question is it possible for scalar attribute . For example in a single SNMPSET request if manager is trying to set three attribute (say ipaddress, netmask, and gateway). Suppose setting of gateway fails then is it possible to set the old value of IP address and netmask ? In case of scalar also we will have different handler.

Now how we can delete the first row? As execution of first handler is finished. Is there any way to return back to the first handler? That's why the Net-SNMP agent uses a multi-pass approach to SET requests. Please read the section on SET handling in the file AGENT.txt. This refers to the old v4 MIB module API, but the basic model applies to the v5 handler-based API as well. Bottom line, the agent won't move from one pass to the next until *ALL* the varbinds have been processed. So the agent will do something like: handle_table1( RESERVE1 ); handle_table2( RESERVE1 ); handle_table1( RESERVE2 ); handle_table2( RESERVE2 ); handle_table1( ACTION ); handle_table2( ACTION ); handle_table1( COMMIT ); handle_table2( COMMIT ); If any of these fail (say handle_table2(ACTION)), then the agent will call *both* handlers with the appropriate failure mode: handle_table1( UNDO ); handle_table2( UNDO ); That's where you'd need to take care of deleting the newly-created row again. Which helper(s) are you using? Most of the automatically-generated code ought to include the basic framework to do this. Dave - Take Surveys. Earn Cash.

Defination of lexicographic ordering
Hi ALL,
I have a doubt about lexicographic ordering. Suppose we have table as
defined bellow
UserEntry OBJECT-TYPE
SYNTAX FmxUserEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
The entry contains data for a user.
INDEX { UserName }
::= { UserTable 1 }
UserEntry ::= SEQUENCE {
UserName
DisplayString,
UserPassword
DisplayString,
UserAccessRights
DisplayString,
UserLanguage
DisplayString,
UserWebCtPoolIntervel
Integer32,
UserStatus
RowStatus
}
Now suppose user has created three rows with the following index
somenath,raghu,arun. Suppose the OID of username is 1.2.3.4.5.6 . So the
OID of the index willbe 1.2.3.4.5.6.somenath,
1.2.3.4.5.6.raghu,1.2.3.4.5.6.arun .But how are we going to decide the
Lexicographic order of these entries ?
Please help,

RE: Getnext Implementation
Hi Dev,
Many thanks for your response. But my
problem is little different. Suppose we have one table having indexs data
type as integer.
Suppose it has three rows with index 1, 2,
3. But the info about the rows are not stored in the index .It is stored in the
data base. Now if some query comes with only column name of that particular
table how agent is going to decide that the next index is 1?
For example suppose we have the following
table
NetworkDhcpPoolSubnetEntry ::= SEQUENCE {
NetworkDhcpPoolSubnetIndex INTEGER,
NetworkDhcpPoolSubnet IpAddress,
NetworkDhcpPoolNetmask IpAddress,
NetworkDhcpPoolSubnetMask IpAddress,
NetworkDhcpPoolSubnetStatus RowStatus
}
Suppose the query is like getnext NetworkDhcpPoolSubnet
. Then how agent will come to know that it has to return the value of NetworkDhcpPoolSubnet.1
. Please let me know if it is possible.
Thanks in advance.

Somenath

The agent is reporting on the information that it knows about - that
currently exists.
If it received a GETNEXT request that affects a table, it should
return the next index for the contents of the table at that particular
point in time. Yes - other rows might be created in the future,
and
that would mean different results for the same request.
But the agent can't predict the future - all it can do is
report on
what it knows about at the time. So whether rows can be
created./deleted or not is irrelevant - take the current contents of
the table, and report one the next existing row.

Then the agent needs to know this.
Not just what the syntax of the indexing is, but what the currently
valid indexes actually are.
Or at the very least, it needs some way to find out about the next
index.
Will the rows of this table always be consecutive starting from 1?
Not necessarily. It was one simple example.
The index may be IPADDRESS also
Or will there sometimes be gaps? If so, then small gaps or
large gaps?
For this particular table there can be
large gap
But the info about the rows are not stored in the index .It is
stored in the data base.
That's not a problem.
Now if some query comes with only column name of that
particular table how agent is
going to decide that the next index is 1?
If the table indexes are consecutive (or nearly so), then the first
index will *always* be 1.
It may not always starts with 1.
The MIB module can just take the index from the incoming request, add
1 (or use 1 in the case above), and request that row from the
database.
If the rows are strictly consecutive, then the first row that doesn't
exist will mark the end of the table, and the MIB module can return
failure.
If there are occasional gaps, then if a row doesn't exist, the MIB
module will need to try again with the next index. This also implies
some other mechanism for detecting the last row of the table.
If there are large gaps (e.g. using processIDs, or semi-random index
values), then this approach probably isn't appropriate.
There needs
to be some way to calculate or ask for the next valid
index.
For example suppose we have the following table
NetworkDhcpPoolSubnetEntry ::= SEQUENCE {
[snip]
}
The structure of a table row is irrelevant. The first task
is always
to determine which row of the table is required (ignoring the column
information).
How is the table populated initially, how is it updated, and how
rapidly will it change?
The table does not have any row initially
.The user need to create the row .Then the column can be modified. This table
is not rapidly changed.

Somenath

How is the table populated initially, how is it updated The table does not have any row initially .The user need to create the row . How? Via an SNMP SET command? Or via some other control mechanism? The table may be created by another agent (for example http agent) If the table is purely controlled via SNMP, then there's no problem whatsoever. The agent is the only thing that creates rows, so it knows exactly what rows exist, and can keep a track of the indexes. Determining the next index is simply a matter of searching this internal list. The Net-SNMP agent has several helpers that can take care of this automatically. If rows can be created behind the back of the agent, then things are slightly harder. The most straighforward approach would be for the agent to hold a cache of the table (or at least of the row indexes), Does it mean if the table is created by http agent, SNMP agent should know about the index which is created by http agent? How it is possible? and use that. Occasionally, when the cache is regarded as too old to be useful, it can be refreshed from the underlying system. The mib2c tool can generate code for either of these approaches. Dave Regards, Somenath - Take Surveys. Earn Cash.

In terms of behaviour of the SET request - no. The protocol used by SNMPv2c and SNMPv3 is identical. (Strictly speaking, both SNMPv2c and SNMPv3 actually use SNMPv2 protocol requests. But that's not important right now). The difference lies in the administrative information, used to decide whether or not to accept a particular request. SNMPv2c has the very simple community-based admin mechanism. SNMPv3 has a much more powerful (secure, complex) administrative framework - supporting proper authentication, encryption, etc. But the basic protocol operations are the same. Dave - Take Surveys.

I have generated the .c and .h using mib2c and then generated libmhso.so .I kept the .so in /tmp/MH directory and all the other netsnmp libraries in /tmp/rh/lib.

But while trying snmpget on that particular private mib attribute whose implementation is part of .so I am getting the error snmpget -c public -v2c localhost mclbVcbMhHeartBeatTimeout.0 MCLB-VCB-MIB::mclbVcbMhHeartBeatTimeout.0 = No Such Object available on this agent at this OID My question is 1) Is it possible to keep the mib2c generated .c .h files in some other directory (other than agent/mibgroup) and force the configure scripts to include those files while making snmpd ? 2) Is there any way to force --with-mib-modules to look for .c and .h other than agent/mibgrop directory 3) Is it possible to implement the mibs and generate .so and while configuring snmpd include that .so instead of --with-mib-modules option and still the private mibs which implementation is part of .so gets loaded.

I mean user should create row first then only he can change the values of column of partiuclar row.
That is, he should not be able to set any thing before creating that row.In current implementation
he is able to set values of particular row with out setting the rowstatus = 4 .

But how are you maintaining the table?
The code snippet you included said
*NOTHING* about what
approach you are taking! Which
helper(s) you might be
using,
Example of create
Hi ALL, I am new to this SNMP world. I need to develop agent which implements some private MIBS. Can any one help me by providing an example code for creating and removing table entry using NET-SNMP API. Thanks, Somenath
RE: Example of create
Hi Dave,
Thanks for replying .I have written the code
for create. I am able to create and get. But I am not able to delete the row .I
am using netsnmp stack for storage. In create I am dong nothing.
switch
(*request-requestvb-val.integer) {
case RS_CREATEANDGO:
snmp_log (LOG_DEBUG,INSIDE RS_CREATEANDGO\n);
break;
case
RS_DESTROY:
snmp_log
(LOG_DEBUG,INSIDE RS_DESTROY \n);
break;
With this code I am able to create but not delete.
I am attaching the result. Please help.
Thanks,
Somenath

Have you looked at the code under 'agent/mibgroup' ?
There are *plenty* of examples there, using a wide variety of
approaches.
