Determine the IP address of an eth interface

[billie]

Hi all. I'm searching for a module that permits me to low-level interact
with ethernet interfaces of my system.
I would like to determine at least the first of the followings values:

1 - IP address assigned to the interface
2 - subnet mask
3 - default gateway
4 - primary and secondary dns
5 - default wins server
6 - mac address
7 - broadcast address

On python cookbook I found this usefuls script that returns the IP address
of a specified interface but it only works on unix platforms. I was
wondering if exist a specific module that could solve this kind of
problems.
Best regards.

import socket
import fcntl
import struct

def get_ip_address(ifname):
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
return socket.inet_ntoa(fcntl.ioctl(
s.fileno(),
0x8915, # SIOCGIFADDR
struct.pack('256s', ifname[:15])
)[20:24])

'127.0.0.1'

'38.113.228.130'

This may depend on your OS. How about:

On win... you may call ipconfig: os.popen('ipconfig /all','r')
- if ipconfig on your default path, otherwise specify full path -
and retrieve the information you want from the output.

Have fun

Not a cross-platform solution (I doubt if there is one, strictly)
but you can use WMI on win32 to get most of what you want. I'm
not sure about the broadcast address, but some Googling around
might help to solve that:

(wmi module from http://timgolden.me.uk/python/wmi.html)

<code>
import wmi
c = wmi.WMI ()
for eth in c.Win32_NetworkAdapterConfiguration (IPEnabled=True):
print eth

</code>
