I really appreciate your reply.  Your suggestion fixed that
problem, however, a new error appeared.  I am doing some
research to try to figure it out but no luck so far.

Traceback (most recent call last):
  File "./ifaces.py", line 33, in <module>
    ifs = all_interfaces()
  File "./ifaces.py", line 21, in all_interfaces
    name = namestr[i:i+16].split('\0', 1)[0]
TypeError: Type str doesn't support the buffer API
