Summary: getaddrinfo and numeric ports

Initial Comment:
Python 2.2.1 here.

Documentación for "socket.getaddrinfo()" says that
"port" can be "a string service name (like ``http''), a
numeric port number or None.".

String service name and "None" work fine. But numeric
ports are not soported under LINUX RedHat:

>>> socket.getaddrinfo("localhost",80)
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
socket.gaierror: (-8, 'Servname not supported for
ai_socktype')

It works fine under Solaris 2.5.1 and Win98.

You have to provide a socket type if you want to specify a
port number; without a socket type (SOCK_STREAM or
SOCK_DGRAM), the port number is meaningless.

So the proper call is

socket.getaddrinfo("localhost",80,0,socket.SOCK_STREAM)
