问题
I am trying to make an SNMP agent following this tutorial: http://www.nealc.com/blog/blog/2013/02/23/writing-an-snmp-agent-with-a-custom-mib-using-pysnmp/
I am using the exact code in the tutorial, but when I run the code it ends in this:
DBG: [19:13:54.964]: file SNMPv2-SMI.pyc mtime 1379957443

The MY-MIB.py that gets generated by build-pysnmp-mib looks like this:
# PySNMP SMI module. Autogenerated from smidump -f python MY-MIB

( Integer, ObjectIdentifier, OctetString, ) = mibBuilder.importSymbols("ASN1", "Integer", "ObjectIdentifier", "OctetString")
( NamedValues, ) = mibBuilder.importSymbols("ASN1-ENUMERATION", "NamedValues")
( ConstraintsIntersection, ConstraintsUnion, SingleValueConstraint, ValueRangeConstraint, ValueSizeConstraint, ) = mibBuilder.importSymbols("ASN1-REFINEMENT", "ConstraintsIntersection", "ConstraintsUnion", "SingleValueConstraint", "ValueRangeConstraint", "ValueSizeConstraint")
( Bits, Integer32, Integer32, MibIdentifier, NotificationType, MibScalar, MibTable, MibTableRow, MibTableColumn, TimeTicks, enterprises, ) = mibBuilder.importSymbols("SNMPv2-SMI", "Bits", "Integer32", "Integer32", "MibIdentifier", "NotificationType", "MibScalar", "MibTable", "MibTableRow", "MibTableColumn", "TimeTicks", "enterprises")
# Objects
myCompany = MibIdentifier((1, 3, 6, 1, 4, 1, 42))
testCount = MibScalar((1, 3, 6, 1, 4, 1, 42, 1), Integer32()).setMaxAccess("readonly")
if mibBuilder.loadTexts: testCount.setDescription("A sample count of something.")
testDescription = MibScalar((1, 3, 6, 1, 4, 1, 42, 2), OctetString()).setMaxAccess("readonly")
if mibBuilder.loadTexts: testDescription.setDescription("A description of something")
# Augmentions
# Notifications
testTrap = NotificationType((1, 3, 6, 1, 4, 1, 42, 3)).setObjects(*() )
if mibBuilder.loadTexts: testTrap.setDescription("Test notification")
# Exports
# Objects
mibBuilder.exportSymbols("MY-MIB", myCompany=myCompany, testCount=testCount, testDescription=testDescription)
# Notifications
mibBuilder.exportSymbols("MY-MIB", testTrap=testTrap)
Does anyone have an idea what could have caused that exception? I've been on Google for the last few hours searching but didn't find anything valuable.
Edit: Also when using the code from http://pysnmp.sourceforge.net/examples/current/v3arch/agent/cmdrsp/v2c-custom-scalar-mib-objects.html I get a similar error:
