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, local_address=('192.168.1.43', 38067), remote_address=('72.14.234.104', 80), status='ESTABLISHED')]
Hope this helps
