How to restrict jgroups from binding to IPv6 address in the case when IPv6 is enabled and configured

[sakthiprabhu]

Hi,

IPv6 is enabled and configured in my server. I have declared a IPv4 address as Multicast address and have removed the property '-Djava.net.preferIPv4Stack=true' from the configuration file. Now jgroups binds to both IPv4 and IPv6 addresses. How to restrict jgroups from binding to IPv6 address in the case when IPv6 is enabled and configured?..

-Djava.net.preferIPv4Stack=true

Thanks Bela,

But this will disable IPv6, right?..

[belaban]

no, it will choose PIv4 addresses

[sakthiprabhu]

I have tried this. By providing -Djava.net.preferIPv4Stack=true I am unable to communicate with IPv6 devices..

[belaban]

Yes, of course, you're forcing IPv4 to be used !

What do you want to achieve: use IPv4 or IPv6 ?

[andreadawson]

thanks it works for me

[sakthiprabhu]

The case is to use Dual stack, but jgroups want to binded with IPv4 alone. Is this case is possible?..

[belaban]

Very unclear what you want to do: if you want to use IPv4, use preferIPv4Stack=true, else preferIPv6Addresses=true.

This is what we are expecting,

Ours is such an application which can comminicate with devices. We dont want Jboss AS to support IPv6. But we should be able to talk to IPv6 devices. You can view both a two different plances, where one plane has jboss bind IP and web IP. The other plane has device management IP. Only device management IP should support v6.

point is, we could have the same interface being both Joss Bind IP and Dev Managmenet IP. But logically, they are seperate.
