Hi
i am facing trobles in using snmpget for more than oneweek.
Also i am not knowing  whether i am doing mistakes in configuring agent(snmpd.


I am extending agent using microsoft visual c++.


what i have done is below.

1. i put NET-SNMP-TUTORIAL-MIB  in the folder c:\usr\share\snmp\mibs

2. i copied nstAgentModuleObject.h  nstAgentModuleObject.h  into C:\net-snmp-5.5\agent\mibgroup\ folder

3.  i added
         #include "mibgroup/nstAgentModuleObject.h"
      to the file  c:\net-snmp-5.5\win32\mib_module_includes.h

       and

    i added
             if (should_init("nstAgentModuleObject")) init_nstAgentModuleObject();

    to the file  c:\net-snmp-5.5\win32\mib_module_inits.h

4. i compile nstAgentmoduleobject.c into agent.( netsnmpmibssdk project)

   The object file  nstAgentModuleObject.obj is located inthe folder C:\net-snmp-5.5\win32\netsnmpmibssdk\debug\

5. i built snmpdsdk project(net snmp agent).

Next i configured the agent .
snmpd.conf contains the following:

###########################################################################

# SECTION: Access Control Setup

# This section defines who is allowed to talk to your running

# snmp agent.

# SECTION: System Information Setup

# This section defines some of the information reported in

# the "system" mib group in the mibII tree.

# syslocation: The [typically physical] location of the system.

# Note that setting this value here means that when trying to

# perform an snmp SET operation to the sysLocation.0 variable will make

# the agent return the "notWritable" error code. IE, including

# this token in the snmpd.conf file will disable write access to

# the variable.

# arguments: location_string

syslocation COMMUNICATIONS-CRL

# syscontact: The contact information for the administrator

# Note that setting this value here means that when trying to

# perform an snmp SET operation to the sysContact.0 variable will make

# the agent return the "notWritable" error code. IE, including

# this token in the snmpd.conf file will disable write access to

# the variable.

# arguments: contact_string

syscontact "GANESH YELLAPU"





I restarted the agent.

c:\usr\bin\snmptranslate -On -IR nstAgentModuleObject.0

.1.3.6.1.4.1.8072.2.4.1.1.1

C:\usr\bin\snmpget  -c public -v 2c localhost nstAgentModuleObject.0

C:\usr\bin\snmpset  -c private -v 2c localhost nstAgentModuleObject.0  i  999

Error in packet.

Reason:not writable <that object doesnot support modification>

Failed object: NET-SNMP-TUTORIAL-MIB::nstAgentModuleObject.0

I tried the below command also.

C:\usr\bin>snmpget -c public -v 1 localhost nstAgentModuleObject.0

    this command showed

What is the mistake?

whether snmpd.conf contains correct configur inforamtion?

i have been sending the same mail for one week.

Please find attachmetns (snmpd.conf, snmp.conf)

kinldy help and suggest me inthis regard.

Looking forward to the response.


Thank you  very much

withregards
