what's the problem of " [Errno 97] Address family not supported by protocol"

[jacky]

I installed tornado 1.2.1 with python2.6. I run my app, but get this traceback message. what's the problem ？

Traceback (most recent call last):

  File "bookkeeper_http.py", line 445, in <module>

    main()

  File "bookkeeper_http.py", line 440, in main

    http_server.listen(options.port)

  File "/usr/lib/python2.6/site-packages/tornado-1.2.1-py2.6.egg/tornado/httpserver.py", line 160, in listen

    self.bind(port, address)

  File "/usr/lib/python2.6/site-packages/tornado-1.2.1-py2.6.egg/tornado/httpserver.py", line 186, in bind

    sock = socket.socket(af, socktype, proto)

  File "/usr/lib64/python2.6/socket.py", line 182, in __init__

    _sock = _realsocket(family, type, proto)

socket.error: [Errno 97] Address family not supported by protocol

Dude, 

I guess that error is not relate with the Tornado,  It is probably your system configuration problem.

Did u configure with the SDP. sometimes the /usr/lib/libsdp.so will disables stream sockets in CentoOS  RHEL4.

This looks related to the new IPv6 support.  What does the socket.getaddrinfo call return for you?  Does it work if you pass family=socket.AF_INET to bind()?
