ValueError: unknown address family 10 | sockaddr = (inet_ntop(AF_INET6, res), port, 0, 0)

[Todd Wilson]

On certain URLs, I get this error that I've been unable to solve:

1. File "/usr/local/python27/lib/python2.7/site-packages/gevent/socket.py", line 637, in create_connection
2.     for res in getaddrinfo(host, port, 0, SOCK_STREAM):
3.   File "/usr/local/python27/lib/python2.7/site-packages/gevent/socket.py", line 777, in getaddrinfo
4.     sockaddr = (inet_ntop(AF_INET6, res), port, 0, 0)
5. ValueError: unknown address family 10
6. <Greenlet at 0x2f37190: <bound method Request.send of <Request [GET]>>(prefetch=True)> failed with ValueError

Also:

>>> from gevent import socket

>>> socket.AF_INET6

10

>>> print socket.inet_ntop(socket.AF_INET6, '\0' * 16)

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

ValueError: unknown address family 10

 

This only occurs for me on CentOS 6.2. Any ideas what I'm missing?

What does the same code do if you import socket from standard python
socket module ?

Ah, oops. Does the same thing. Sorry for posting it here!

Any ideas?

Python not compiled with ipv6 support ?
