Problem w/networking code...

[Micheal Kelly]

Hi all,

I'm trying to obtain some network configuration information using
ioctl() and Python under Linux.  From what I've been told, I can
bind a socket, then use ioctl to query various stats, such as 
IP address, broadcast, netmask, etc...

The example below should (from what I understand) return the IP
address the socket is bound to (which I already know, since I bound
it there in the first place - this is just a test, not very useful.  :)

I end up with the following error:

Traceback (innermost last):
  File "./test.py", line 11, in ?
    fcntl.ioctl(s.fileno(), IOCTL.SIOCGIFADDR)
IOError: [Errno 14] Bad address

Any thoughts?

------------

#!/usr/bin/python
from socket import *
import fcntl, FCNTL, IOCTL

HOST = '192.168.3.52'
PORT = 50007

s = socket(AF_INET, SOCK_STREAM)
s.bind(HOST, PORT)

test = fcntl.ioctl(s.fileno(), IOCTL.SIOCGIFADDR)

print test
