A quick question: Does the Windows Server stop multicast packets? I was exploring clustering today on Fedora 13, and I had to modify my firewall rules to allow multicast.
Here's a nice tool from an earlier thread about clustering. If you run this on your local machine you should see messages. See the thread: http://marc.info/?t=108318895700001&r=1&w=4 And for the tool, see this particular mail message: http://marc.info/?l=tomcat-user&m=108319193624084&w=4 Another thing to look out for is broadcasting to 127.0.0.1. From the document at http://tomcat.apache.org/tomcat-6.0-doc/cluster-howto.html 3. The IP broadcasted is java.net.InetAddress.getLocalHost().getHostAddress() (make sure you don't broadcast 127.0.0.1, this is a common error) Hope this helps. . . . . just my two cents /mde/ ----- Original Message ---- From: Andrew Bruno <andrew.br...@gmail.com> To: Tomcat Users List <users@tomcat.apache.org> Sent: Thu, July 15, 2010 5:39:28 PM Subject: Re: No members active in cluster group >Are both instances running on the same host Yes, both running on same host.
