Summary: socket.inet_aton() succeeds on invalid input
Initial Comment:
Given a string such as "5.6.7", inet_aton() returns
'\x05\x06\x00\x07'. In C (using libraries installed
with RedHat 7.2), the equivalent call returns 0,
indicating that the address is invalid.

I can't see the problem. First, 5.6.7 is really a valid
denotation of an IP number, and denotes the IP address
5.6.0.7, just like 10.13 denotes 10.0.0.13.
Furthermore, Python uses inet_addr on the C level, which
does not return a status; for the address given, it returns
exactly the same result that you see in Python.
Finally, I cannot reproduce inet_aton(3) returning an error:
on my installation (SuSE 8.1), it returns 1, indicating success.
