On mine it is exactly:

http               80/tcp    www www-http           #World Wide Web

Well, to judge from the failing assert in isolation, getservbyport() is
returning "http", but the test expects "www" ... yup:

Python 2.4a0 (#46, Jul  5 2004, 18:32:20) [MSC v.1310 32 bit (Intel)] on
>>> import socket
>>> socket.getservbyname('www', 'tcp')
>>> socket.getservbyport(_)

The other name are accepted too:

>>> socket.getservbyname('http', 'tcp')
>>> socket.getservbyname('www-http', 'tcp')
