Hello,

Yes, that is pretty much the error I get.    I don't even have the latest 1.6 JDK, just the JRE, so the ' import java' route was useful.

Jython 2.5.2rc4 (Release_2_5_2rc4:7200, Feb 14 2011, 23:43:30)
[Java HotSpot(TM) 64-Bit Server VM (Sun Microsystems Inc.)] on java1.6.0_24

>>> import java
>>> ipv6_addr=java.net.InetSocketAddress("::1",9999)
>>> s=java.nio.channels.SocketChannel.open()
>>> s.socket().connect(ipv6_addr)

java.net.SocketException: java.net.SocketException: Address family not supported

I conclude that JRE6 64bit has some IPv6 problems still. Do you think I should try to report that to Oracle/Sun/Java folks?

The Windows 7 install should be pretty clean, I did it from a MS disk since I am basically the IT department :-).   I guess I could also try this with the 32 bit JRE and see if it works (not sure the 32 bit JRE will even run under 64 bit Windows).

Thanks for the fast feedback and diagnosis,

Peter

Here is the same code in jython, but using the Java APIs directly, with no involvement from the jython socket module.

>>> import java
>>> ipv6_addr = java.net.InetSocketAddress("::1", 9999)
>>> s = java.nio.channels.SocketChannel.open()
>>> s.socket().connect(ipv6_addr)

Which I think will result in something like this on your system
