Perhaps this is another small bug in the snmpwalk.py example.

I try to walk this OID: 1.3.6.1.2.1.1.3

And the error raised is:

Traceback (most recent call last):
  File "snmpwalk.py", line 132, in ?
      raise str(rsp['pdu'].values()[0]['error_status']) + ' at '\
IndexError: list index out of range

Here's my v2c.Response() object printed:

Response(version=Version(1), community=Community('xxxxxxxxxx'),
pdu=Pdus(response=ResponsePdu(request_id=RequestId(1026),
error_status=ErrorStatus(5), error_index=ErrorIndex(0),
variable_bindings=VarBindList())))

I see the problem is that this line of code:

    raise str(rsp['pdu'].values()[0]['error_status']) + ' at '\
          + str(vars[rsp.apiGenGetPdu().apiGenGetErrorIndex()-1][0])

In this case, the problem lies with the fact that vars is an empty list:

>>> vars = rsp.apiGenGetPdu().apiGenGetVarBind()
>>> vars
[]

I think the device which generated the response isn't doing something
right either, but that's another problem.

Take care.
