This line seems suspect.  The resulting string passed to popen will be
along the lines of
    LANG=""/sbin/ifconfigippp0
try running this at the prompt and you'll get nothing. (Well, actually,
the value of LANG will be set to a new value:
    $ echo $LANG
    /sbin/ifconfigippp0

When I write Python code that assembles strings, I'm much more likely to
use %-formatting than use + for concatenation:
    cmd = os.popen('LANG="" /sbin/ifconfig %s' % (interface,))
etc

best of luck,
