sniffer in python

[billiejoex]

Thank you for your fast reply. You're right. I'll be more specific, sorry.
The example source is the one you can find on the 'Impacket' page on the 
same site of pcapy:
http://oss.coresecurity.com/impacket/sniff.py
I use a Win XP prof sp2 system, python ver. 2.4.1.
Here's the output:

C:\Python24>1.py
Traceback (most recent call last):
File "C:\Python24\1.py", line 107, in ?
