Hi,
I'm trying to get some IPV6 python code running under
Windows. I have installed Python 2.5.1 for Windows
using the binaries from python.org. I'm a newbie to
Python programming as well.
The code works fine under Debian and MacOSX (both
using Python 2.5)
I have rebuilt the python binaries from source and set
ENABLE_IPV6. This didn't help. I have also read about
not being able to bind to a IPV4 and IPV6 socket. I
tried setting the setsockopt() call using IPV6_V6ONLY,
but this is not recognized by the python interpreter.
Thanks for any help I can get. I'm stuck on this and
searching the NET for help.
I get the following error:
C:\test_py>python ipv6.py
Traceback (most recent call last):
File "ipv6.py", line 119, in <module>

Thanks.
