Re: [jgroups-users] Auto Discovery Question

Yes, I have tried bind_addr, didn't help. And I think the infrastructure
supports IPv6, but I'll try your suggestion anyway.
Also, I've switched to TCP from UDP, and it works on the Data Center just
fine. I had to add the hosts into the configuration though. So, the cluster
is not totally dynamic, but as long as I have some seeds, it looks like it
sniffs out all other nodes. I think I can live with that.

But the strange thing, that locally it stopped working, when I run 2
processes on the same machine but different ports. Somehow the nodes don't
see each other. But I'll dig more, maybe there is something wrong in my set
up.

Thank you,
Eugene
