# python
>>> import socket
>>> s = socket.socket(socket.AF_INET6, socket.SOCK_DGRAM)
>>> sa = ( 2000::1 ,2000,0,0)
>>> s.connect(sa)
>>> sa = ( fe80::21b:78ff:fe30:7c6 , 2000, 0, 0)
>>> s.connect(sa)
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "<string>", line 1, in connect
socket.error: (22, Invalid argument )
