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

validated this MIB against smilint ,
put it in ~/.snmp/mibs/
have the rwcommunity string for all host, with no OID restriction
restarted the snmpd daemon (On Debian)

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?
