Hi folks! In a previous post I talked about using Impacket and Pcapy on Python 2.6. Since those installers are now out of date, here are fresh ones for various versions of Pcapy and Python, built against WinPcap 4.1.2. There’s also a new Impacket MSI installer that works against all Python versions.
Enjoy! 
Edited 6-May-2013: updated Impacket to version 0.9.10

Trying to install pcapy on Windows7. The Impacket-0.9.8.0.win32.msi installer seems to have worked, i.e. I now have a impacket dir in my Python27/../site-packages. However,
pcapy-0.10.5.win32-py2.7-winpcap4.1.2.exe is not working. The installer finds Python27 on my machine, but the install seems to complete instantaneously; no error messages, and does not create a pcapy directory in site-packages.

Have you tried running the exe with elevated privileges? If that doesn’t work let me know if you’re using 32 or 64 bit versions of Windows and Python and I’ll try to reproduce the problem…

it doesn’t work for me either even if I run the exe with administrator privileges. same procedure occurs.

Tried the pcapy installer for python 2.6 (from above). This seems to fail in the same way as the installer for 2.7, i.e. all seems to go well, finds the 2.6 installation, but then runs to completion without installing pcapy and without indicating any errors.

Tried to enter this information here before, but for some reason the comment would not post; trying again:
Windows 7 64-bit, python 32 bit, WinPcap 4.1.2. Again, Imapacket 0.9.8 installer above works for both 2.6 and 2.7, pcapy does not work for either.

Downloadlinks for impacket are not working.

Well, this is ackward. I’ll fix it tonight when I get back home then. Thanks!

Fixed! Turned out there was a capital “I” when it should have been in lowercase.
