Hi again!

I've tried the modified snmpwalk.py, but it still fails.  I don't think the 
problem is snmpwalk.py anymore, but rather (I guess) role.py.  The error is 
the same.

Traceback (most recent call last):
  File "D:\pysnmp\examples\snmpwalk.py", line 135, in ?
    client.send_and_receive(req.encode(), (None, 0), cb_fun)
  File "d:\pysnmp\pysnmp\mapping\udp\role.py", line 180, in send_and_receive
    raise error.NoResponseError('No response arrived in %d secs * %d retries' %
(self.timeout, self.retries))
pysnmp.mapping.udp.error.NoResponseError: No response arrived in 1 secs * 5 
retries

But when I do a trace, I can see that the response contains the data I'm 
looking for:
