The Windows part slipped under my radar. =) Unfortunately the Windows binaries still refer to the current version which doesn't include open files and open connections functionalities. To have those he'll have to get the latest code from svn and compile it with mingw32.

Of course it would be nice to get access to FD stack so that a full filename can also be retrieved in this case. On Linux, this can be easily achieved by using /proc. You can take a look at how this is done in the current development version of psutil: http://code.google.com/p/psutil/source/browse/trunk/psutil/pslinux.py?spec=svn633&r=630#266 Usage:

import psutil, os thisprocess = psutil.Process(os.getpid()) f = open('file.ext', 'w') thisprocess.getopenfiles() ['/home/giampaolo/svn/psutil/file.ext'] Same for sockets, a bunch of lines later: http://code.google.com/p/psutil/source/browse/trunk/psutil/pslinux.py?spec=svn633&r=630#284 import socket s = socket.createconnection(('google.com', 80)) thisprocess.getconnections() [connection(family=2, type=1, localaddress=('192.168.1.43', 38067), remoteaddress=('72.14.234.104', 80), status='ESTABLISHED')] If you can use psutil itself, it has compiled Windows versions for 2.7 and 3.1 https://code.google.com/p/psutil/ -- Terry Jan Reedy
