Hi all,
I'd like to get, in a portable way, a list of all
network adapters on a local machine running some
python code.
socket.gethostname() does not seem enough, as it
only returns one name ; I'd like to get all
available IPs.
I could process ipconfig or ifconfig outputs, but
this is OS-dependant and not very future-proof...
Best regards,
Olivier Parisy.

This has been discussed quite a few times on this NG, search google groups.
However IMHO there is no general system built-in way (AFAIK not even posix)
for doing this, you'll end up parsing tool output anyway...

I should have done this first, my mistake...
But actually, a previously posted message suggests a portable way to get
the platform IPs. Citing John Abel :
socket.gethostbyaddr( socket.gethostname() ) will return all the
details that you need to know. For example, the output of that
command on my machine is :
('hallows', [], ['101.101.101.102', '10.253.1.118'])
Are there some pitfalls I'm not aware of ?
Thanks,
Olivier Parisy.

Doesn't seem to work right on Windows, for me at least: socket.gethostbyaddr(socket.gethostname())
('<my machine name>', [], ['169.254.0.100'])
It returned the least useful of my 3 IP addresses - my loopback adapter
- but didn't return my LAN and wireless IPs.

If anyone really needs it, I can post code for windows using ctypes to
collect ip-addresses and netmasks together with the name and description
of all network adapters.

Interesting! I have Python installed on 10 W2K servers and I'm using
the same construct to get addresses. Works fine for me.

WinXP Pro here - I wonder if that's the difference.

Interestingly, I have the same problem with XP Pro.
But socket.gethostbyname_ex seems to do the trick for me !
