I have been trying to understand how to create a MIB : here what I did so far :
I created a MIB, and tried to allocate values to new OID => fail
Here is the MIB :
TEST-MIB DEFINITIONS ::= BEGIN
IMPORTS
MODULE-COMPLIANCE, OBJECT-GROUP FROM SNMPv2-CONF
OBJECT-TYPE, Integer32,MODULE-IDENTITY FROM SNMPv2-SMI;
test MODULE-IDENTITY
LAST-UPDATED "201112190200Z"
ORGANIZATION "blah"
CONTACT-INFO
"please"
DESCRIPTION
"I am stuck"
REVISION "201112190200Z"
DESCRIPTION
"initial Draft"
::= { iso org(3) dod(6) internet(1) private(4) enterprises(1) 39106 }
testResearch OBJECT IDENTIFIER ::= { test 2 }
testVar OBJECT-TYPE
SYNTAX Integer32
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"just for testing"
::= { testResearch 1}
-- conformance information
testMIBConformance OBJECT IDENTIFIER ::= { test 999 }
testMIBCompliances OBJECT IDENTIFIER ::= { testMIBConformance 1 }
testMIBGroups OBJECT IDENTIFIER ::= { testMIBConformance 2 }
-- compliance statements
testMIBCompliance MODULE-COMPLIANCE
STATUS current
DESCRIPTION
"blah."
MODULE -- this module
MANDATORY-GROUPS { testGroup }
::= { testMIBCompliances 1 }
-- units of conformance
testGroup OBJECT-GROUP
OBJECTS { testVar }
STATUS current
DESCRIPTION
"The draft"
::= { testMIBGroups 1 }
END
I then
So far, all good.
I then tried to see if the daemon knows about this new enterprise, and I did :
snmpwalk -v2c -m +ALL localhost .1.3.6.1.4.1.39106
which outputs : TEST-MIB::test= No Such Object available on this agent at this OID
So I guess That snmpd is telling me he can't find anything under this tree, because nothing has been set yet.
So I try to set this test variable with snmpset on a shell :
snmpset -v2c -m +ALL localhost .1.3.6.1.4.1.39106.2.1 i 111
outputs :
Error in packet.
Reason: notWritable (That object does not support modification)
Failed object: TEST-MIB::testVar
I tried as well with : snmpset -v2c -m +ALL localhost .1.3.6.1.4.1.39106.2.1.0 i 111
and as root, but with no success
But when I do a snmptranslate, I can see that the MIB is parsed correctly :
snmptranslate -Td 1.3.6.1.4.1.39106.2.1
TEST-MIB::testVar
testVar OBJECT-TYPE
-- FROM TEST-MIB
SYNTAX Integer32
MAX-ACCESS read-write
STATUS current
DESCRIPTION "just for testing"
::= { iso(1) org(3) dod(6) internet(1) private(4) enterprises(1) test(39106) testResearch(2) 1 }
is it a bug? A known issue?
It sounds like you're trying to build your own SNMP Agent.
By the looks of things you've created your own MIB OID's correctly but nothing is responding to the new OID when you query the SNMP host.
Have a read of this: http://docs.oracle.com/cd/E13192_01/manager/mgr20/pguide/buildag.htm and see if it addresses your problem q:)
