ApacheDS and ipv6 support on windows
Hi All,
I was recently flabbergasted to find out that no Sun JDK 1.5+ supports NIO
sever support over ipv6 on any version of Windows (due to lack of support
for dual-mode sockets in the underlying Windows stack implementation), and
that the situation is only likely to be resolved in the future in JDK 7 on
top of Vista (refer
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6230761 ).
Hence my current understanding is that clients who want ApacheDS to listen
on an ipv6 socket at start-up will have to use a Unix variant on which the
JDK doesn't suffer this problem. Have I missed / misunderstsood anything
here, or is there perhaps another JDK implementation with an enhanced NIO
implementation (or some other cunning technique) that may represent a "get
out of jail" card for me and my clients as far as pre-Vista Windows is
concerned?
Many thanks.

Cool I did not know the API transport bought us all that.
Excellent! Thanks for the hint.

Thanks for the feedback. Further research has convinced me that the NIO
library implementation in the JRockit VM suffers the same problem,. I didn't
find anything explicitly referring to the IBM VM implementation in regards
to this issue, but I have very little hope in that direction now either.
Hence I think the only solution to ipv6 support is to recommend deployment
on Unix, until a) jdk 1.7 is patched and b) there is a server variant of
Windows that has the IPV6 stack support released in Vista.

Hi,
I don't see simple answer to this question, except waiting jdk7.
But with MINA2.0, and the APR based Acceptor/Connector you have
everything for bind an IPv6 port on Windows if APR support it.
I'm not sure to help a lot there ;)

Re: ApacheDS and ipv6 support on windows
Posted by Norval Hope <nr...@gmail.com>.
I'm cross posting this query to the MINA dev list about support for ApacheDS
listening on an ipv6 socket on Windows.
My first posting was:
-----------------
I was recently flabbergasted to find out that no Sun JDK 1.5+ supports NIO
sever support over ipv6 on any version of Windows (due to lack of support
for dual-mode sockets in the underlying Windows stack implementation), and
that the situation is only likely to be resolved in the future in JDK 7 on
top of Vista (refer
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6230761 ).
Hence my current understanding is that clients who want ApacheDS to listen
on an ipv6 socket at start-up will have to use a Unix variant on which the
JDK doesn't suffer this problem. Have I missed / misunderstsood anything
here, or is there perhaps another JDK implementation with an enhanced NIO
implementation (or some other cunning technique) that may represent a "get
out of jail" card for me and my clients as far as pre-Vista Windows is
concerned?
Many thanks.
--------------------
As MINA (very sensibly) uses NIO server socket channels, it unfortunately
seems there will be a problem until an extension is made to JDK 7 running on
top of Vista. Note the bug link above provides a test program which can be
used to verify whether a particular configuration displays the problem or
not.
I'm not sure if running a different JDK implementation may help due to
different bundled NIO implementations, but this is most probably not really
an option for my customers.
Any help / comments greatly appreciated.
Thanks

The problem is that IPV6 is the default stack on Windows... Unless we
see an urge of Linux and MacOSX stations, we may have some kind of
problem... (btw, I think that linux will see a huge increase as Asus eee
and similar computers will be sold by millions soon ...)
But I thought that if your desktop is IPV6 based, it should still be
able to communicate with a IPV4 stack, otherwise, I can't see how those
millions computers installed with many flavors of
W$+Virii+spywares+rootkits will be able to connect to all those retarded
web sites which still use Linux + Apache HTTPd server on a IPV4 stack ...
Don't know exactly... I'm not really a specialist. May be posting this
question to MINA will be the best move !

I don't know about this but MINA may be a consideration here. Does MINA
allow for IPv6? Does it care?
I've not even considered IPv6. I'm not really interested in it at this
point but if we have to move to JDK 1.7 to support it people are going to be
really pissed off. Yet another ugly balancing act.

Have you tried with JRockit or IBM JVM?

Thanks for the feedback.
However, my problem is the other way around - i.e. the client wants ApacheDS
to listen on an ipv6 socket only.

You should be able to make it work using this flag to the JVM CL :
/-Djava.net.preferIPv4Stack=true/
The server will now listen on an IPV4 socket at startup.
Hope it helps.
