thanks for you suggestions!

apparenlty, it doesn't. :-(
I changes the except block into
except Exception, e:
print e
and added
if __name__ == '__main__':
print ifconfig('ng0')
print ifconfig('vr0')
print ifconfig('vr2')
print ifconfig('xl0')
ng0 exists and has an IP (virtual interface created by mpd)
vr0 exists but does not have an IP (phisical interface for mpd)
vr2 exists and has an IP configured
xl0 does not exist
output:
[Errno 25] Inappropriate ioctl for device
{'ifname': 'ng0'}
[Errno 25] Inappropriate ioctl for device
{'ifname': 'vr0'}
[Errno 25] Inappropriate ioctl for device
{'ifname': 'vr2'}
[Errno 25] Inappropriate ioctl for device
{'ifname': 'xl0'}
however, in Linux I get the following results:
[Errno 99] Cannot assign requested address
{'ifname': 'eth0'}
{'hwaddr': '0:17:f2:4c:a5:c', 'ifname': 'ath0', 'netmask': '255.255.255.0',
'addr': '192.168.50.104', 'brdaddr': '192.168.50.255'}
{'hwaddr': '0:0:0:0:0:0', 'ifname': 'tun0', 'netmask': '255.255.255.255',
'addr': '192.168.3.6', 'brdaddr': '0.0.0.0'}
[Errno 19] No such device
{'ifname': 'wielewoele'}
which seems 100% correct.

Calvin: So?
Susie: It's wrong to get rewards you haven't earned.
Calvin: I've never heard of anyone who couldn't live with that.
